| (57) A dispenser for a packaging bag, which includes a box body accommodating therein
multiple sheets of the packaging bags and a weight means for pressing the packaging
bag accommodated in the box body. An opening portion having sufficient size for taking
out the packaging bag is formed on the upper area of the box body. |
[0001] This invention relates to a dispenser for a packaging bag to take out each unique-shaped packaging bag and a method for producing the same.
[0002] As a packaging bag in order to carry away merchandise such as "a take-away", groceries, confectionery, a souvenir and so on, conventionally, a packaging bag made of synthetic resins has been used. The packaging bag is accommodated in a dispenser for a packaging bag of which there are many, and it has been required to securely take out each bag separately.
[0003] As the packaging bag, a grocery-bag of a T-shaped type has been generally used, in which various devices for taking out each grocery-bag separately have been proposed. For example, a device in which the packaging bag is fixed by a support arm (see Japanese Patent Application Publication No. Hei. 6-31082) is actually used.
[0004] Apropos, the conventional packaging bag is handled to be opened by one hand so that the merchandise can be put into the packaging bag by the other hand, and further, the shape of the merchandise changes with its posture in the packaging bag, therefore, much expense in time and effort is needed, especially, for the operation of a shop assistant during a crowded time period when there are many customers, it is unsuitable.
[0005] In order to resolve the aforementioned disadvantages, Japanese Patent Application Laid-open No. Hei. 6-298261 and Japanese Patent Application Laid-open No. Hei. 8-58808 propose a unique-shaped packaging bag for a customer to take away the merchandise. Fig. 39A and Fig. 39B each show a packaging bag having the same structure as the aforementioned proposed packaging bag.
[0006] As shown in Figs. 39A and 39B, the packaging bag 100 has; a bottom portion 101 having two mutually opposed sides 101A and 101B; a first side portion 102 extending from the two mutually opposed sides 101A and 101B to the vicinity of the middle area of the bottom portion 101; and a second side portion 103 extending from the end of the vicinity of the middle area of each first side portion 102 to the outer area of two mutually opposed sides on the other side of the first side portion 102 from the bottom portion 101, in which a hand-slot portion 104 is formed on each second side portion 103, and the vicinity of both end sides of the first side portion 102 is joined to the bottom portion 101.
[0007] The merchandise is put on the packaging bag 100 to spread over both second side portions 103, and further the hand-slot portions 104 are held to pull the second side portions 103 to the right and the left in the direction which the second side portions 103 are mutually maintained with an interval, and each of the second side portions 103 is pulled out from immediately beneath the merchandise, resulting in automatic packaging of the merchandise.
[0008] The aforementioned packaging bag 100 is, however, a unique shape, so that a device described in Japanese Patent Application Publication No. Hei.6-31082 cannot be used in order to take out every packaging bag. Therefore, a dispenser for a packaging bag, which is capable of taking out each unique-shaped packaging bag, has been required conventionally.
[0009] A shop, such as a supermarket, a grocer shop, a bakery shop and so on, has a service whereby any merchandise purchased by a customer is packed into a synthetic resin made bag.
[0010] As with the synthetic resin made packaging bag, bags having various configurations, such as the aforementioned grocery-bag of a T-shirt type, are used, but, when they are used in the piled state on top of one another, a place for putting the synthetic resin made bag is needed and there is difficulty in separating each bag, resulting in the disadvantage that the merchandise is inefficiently delivered to the customer.
[0011] From the view of the aforementioned disadvantages, various dispensers for the synthetic resin made packaging bag have been conventionally proposed.
[0012] The conventional dispenser is composed of a bag support body for supporting multiple folded synthetic resin made bags and a box body accommodating therein the bag support body, in which a take-out port is formed on the upper wall of the box body in order to take out the aforementioned bag.
[0013] In the dispenser as described thus far, fingers are put into the take-out port formed on the upper wall of the aforementioned box body to pick up the bag by pinching around the top portion of the aforementioned folded packaging bag, thereafter each packaging bag is taken out from the inside of the case body.
[0014] Almost the same structure to the dispenser, Japanese Utility Model Application Laid-open No. Sho. 53-5246, Japanese Utility Model Application Laid-open No. Sho. 52-5831, Japanese Utility Model Application Laid-open No. Sho. 52-87431, and Japanese Patent Application Laid-open No. Sho. 52-132978 is proposed.
[0015] By accommodating the packaging bag which is folded, the dispenser, having the aforementioned structure, is purposed that an area for placing the box body be smaller and the synthetic resin made bag should be easily picked up with fingers by forming the top portion.
[0016] However, the synthetic resin made bag is formed to be extremely thin by materials having a slippery face, such as polyethylene, polypropylene and so on, is accommodated into the case body in a piled state with a multiple number of bags, whereby it remains difficult to certainly take out each synthetic resin made bag.
[0017] It is an object of the present invention to provide a dispenser for a packaging bag which is capable of smoothly taking out each unique shaped packaging bag separately and a method for producing the dispenser for the package.
[0018] In consequence, a first dispenser for a packaging bag according to the present invention is characterized by including a box body accommodating therein multiple packaging bags and having an opening portion having sufficient size to take out the packaging bag at its upper area; and a weight means for pressing the packaging bag placed in the box body.
[0019] In the aforementioned dispenser, the box body is previously accommodated with a packaging bag having a special configuration, for example, the packaging bag having a bottom portion having two mutually opposed sides, a first side portion extending from the two mutually opposed sides to the vicinity of the middle area of the bottom portion, and a second side portion extending from the end in the vicinity of the middle area of the bottom portion extending the first side portion to the vicinity or the outer area of the two mutually opposed sides in the opposite direction from the bottom portion on which the first side portion is placed, in which the vicinity of both sides of each first side portion is connected to the bottom portion and the outer area of the two mutually opposed sides of the second side portions is provided with hand-slot portions. A piece of merchandise is put on the top packaging bag of the multiple packaging bags accommodated in the box body, and in this condition, the packaging bag is pulled out from the opening portion. Even if the multiple packaging bags are accidentally pinched together, only one packaging bag is taken out by the weight means.
[0020] Here, the packaging bag is accommodated in the box body to orientate the second side portion face up and the bottom portion face down; and the weight means is a plate-shaped member formed on the opening portion, and further, the box body may be provided with an expanded portion formed to be expanded in the vicinity for placing the hand-slot portion of the packaging bag from the box body so that the hand-slot portion is deployed.
[0021] In the aforementioned structure, the merchandise is put on the top packaging bag of the multiple packaging bags accommodated in the box body, and in this condition, both hand-slots of the packaging bag are pulled up until above the expended portion by spreading in the right and left directions. Even if the band-slots of multiple packaging bags are accidentally pinched together, by pulling the top-positioned hand-slot placed on the expanded portion out until above the expanded portion, only one packaging bag can be taken out by disjoining from the weight means. Furthermore, as it is, by pulling both hand-slots upward, the merchandise is packaged.
[0022] Further, the dispenser of the aforementioned structure may be structured to have a sending roller sending the band-slot or the vicinity of the hand-slot of the packaging bag accommodated in the box body to the expanded portion.
[0023] In the aforementioned structure, provided that the sending roller is operated by hand, a machine such as a motor or the like, the hand-slot, placed on the top of the packaging bags accommodated in the box body, is sent out to the expanded portion, with the result that only one packaging bag can be smoothly taken out.
[0024] The aforementioned dispenser may have a structure in which the box body is formed on the side face of the box body with a recess portion in order to pull out the hand-slot portion of the packaging bag accommodated in the box body.
[0025] In the aforementioned structure, the merchandise is put on the top packaging bag of the multiple packaging bags accommodated in the box body, in this condition, both hand-slots of the packaging bag are spread toward the right and left directions. Here, the end of the second side portion is slightly exposed from the recess portion, so that only one of the multiple packaging bags can be separated. Further, by pulling up the hand-slot, only one packaging bag is taken out by disjoining from the weight means. And, as it is, by pulling both hand-slots upward, the merchandise can be packaged.
[0026] In the aforementioned dispenser, the weight means is structured to press a specified pressing force on the other hand-slot portion or in the vicinity of the other hand-slot portion of the packaging bag; and the box body may be structured to be formed on the side face of the box body with a recess portion in order to pull out the other hand-slot portion of the packaging body accommodated in the box body.
[0027] In the aforementioned structure, the merchandise is put on the top packaging bag of the multiple packaging bags accommodated in the box body, in this condition, one of the hand-slots of the packaging bag is pulled out in the horizontal direction. Whereupon, half of the merchandise gets packaged with the packaging bag, and further, the other hand-slot is continued to be pulled out in the horizontal direction, whereupon the vicinity of the first hand-slot of the packaging bag is removed against the pressing force of the weight means, with the result that the merchandise is packaged.
[0028] Furthermore, in the dispenser having the aforementioned structure, the box body may have a slope portion causing the other hand-slot portion to slope in the side provided with the recess portion. In this structure, not only the top packaging bag is easily taken out, but also the other packaging bags stored under the top packaging bag are not shifted when the top packaging bag is being pulled out in the horizontal direction.
[0029] In the dispenser, the opening portion is an opening groove forrned on the upper area of the box body to have sufficient size for passing one of the packaging bags; and the weight means is a first roller pressing and delivering the top packaging bag of the multiple packaging bags accommodated in the box body in the horizontal direction, and it may be structured to have a second roller delivering the packaging bag, delivered by the first roller, in the upward direction, and a guide means for guiding the packaging bag, delivered by the second roller, to the opening groove.
[0030] In the aforementioned structure, the first and second rollers are operated by hand or a machine such as a motor or the like to send the top packaging bag accommodated in the box body through the guide means to the opening groove. The merchandise is put on the one packaging bag sent from the opening groove taken out, in this condition, both hand-slots of the packaging bag are spread in the horizontal direction to package the merchandise.
[0031] In the dispenser as described thus far, the box body may be structured to have therein a support plate for supporting the packaging bag and momenturn means for forcibly moving the packaging bag upwards to be connectively provided between the support plate and the bottom portion of the box body.
[0032] In this structure, by the momentum means, the packaging bag supported by the support plate is forcibly pressed onto the opening portion or the first roller, so that the packaging bag can be smoothly taken out even when the number of packaging bags accommodated in the box body is fewer.
[0033] A method for producing the dispenser for the packaging bag according to the present invention is a method for producing the dispenser having the aforementioned structure. More specifically, the method for producing the dispenser for the packaging bag which has a box body accommodating therein multiple packaging bags and having an opening portion having sufficient size to take out the packaging bag at its upper area, a weight means composed of a plate member and formed at the opening portion of the box body, and an expanded portion provided in the box body to be formed to be expanded in the vicinity placing the hand-slot portion of the packaging bag from the box body so that the hand-slot portion is deployed, is characterized by having the steps of: forming a perforated line for bordering the outer area of the box body and the weight means on the box body accommodated for the packaging bag; forming an opening portion to remove a lid portion from the box body by cutting the perforated line; and projecting the extended portion from the box body by bending the extended portion towards the outside.
[0034] The other method for producing the dispenser for the packaging bag according to the present invention is characterized in which the perforated line, bordering the range of the box body, the weight means and the lid portion, is formed to a box accommodating multiple packaging bags, so that the perforated line is cut to remove the lid portion from the box to form the opening portion and a recess portion.
[0035] In the present invention of the aforementioned producing method, the dispenser can be easily produced by only cutting the perforated line composed of a tear-off strip or the like.
[0036] Next, a second dispenser for the packaging bag according to the present invention is characterized by having a bag support body supporting multiple synthetic resin made packaging bags in the folded state; and a box body accommodating therein the hag support body, in which the box body is formed on its wall face with an opening portion shaped to expose an edge of at least one side of the packaging bag.
[0037] In the dispenser of the aforementioned structure, the outer edge of one side of the synthetic resin made packaging bag can be easily pinched to separate each bag with fingers, therefore, the packaging bag, even the synthetic resin made packaging bag having a slippery surface, can have every bag securely and smoothly taken out from the box body.
[0038] In the second dispenser for the packaging bag according to the present invention, the opening portion is shaped to expose an edge area of two intersecting sides of the packaging bag.
[0039] In the aforementioned structure, the vicinity of the two intersecting sides of the synthetic resin made packaging bag can be easily pinched by separating each bag with fingers, whereby each individual synthetic resin made packaging bag can be further securely and smoothly taken out from the box body.
[0040] The packaging bag has a folded portion for being pinched with fingers; and the opening portion may be formed to expose the folded portion of the packaging bag.
[0041] In the aforementioned structure, the folded portion can be easily pinched by hanging the folded portion of the synthetic resin made packaging bag with fingers, whereby each individual synthetic resin made packaging bag can be further securely and smoothly taken out from the box body.
[0042] The opening portion may be structured to be formed on a wall face of the vertical side of the box body.
[0043] According to the aforementioned structure, dust or the like enters the opening portion creating difficulties, therefore, a hygienic condition of the synthetic resin made packaging bag accommodated in the box body can remain sufficiently.
[0044] The box body may be structured to have a wall face, structuring at least a part of the case body, to be opened in order to change another bag support body without separating from the box body.
[0045] In the aforementioned structure, while the bag support body is changed, a part of the box body is retained to attach to the box body, resulting in a smaller space for setting the box body. Further, the synthetic resin made packaging bag can be restocked in the box body with both hands, whereby the synthetic resin made packaging bag can be smoothly restocked.
[0046] The box body may be placed in the upright slate in which the opening portion is opened to orientate in the horizontal direction.
[0047] According to the aforementioned structure, the space for setting the dispenser is smaller, so that a working area for carrying out packing at a checkout counter, kitchen or the like is used widely.

[0049] The preferred embodiments according to the present invention will be explained below with reference to the attached drawings. Incidentally, in the description of the following embodiments, the same reference numerals will be used to designate the same or similar components as those in the first embodiment, so that the description will be omitted or simplified.
[0050] A first embodiment of the present invention will be explained with reference to Fig. 1 to Fig.9. Fig. 1 shows a perspective view of a dispenser for a packaging bag according to the first embodiment, and Fig. 2 shows a plan view of Fig. 1, and further, Fig. 3 is a sectional view of Fig. 1.
[0051] In the aforementioned drawings, the dispenser 1 for the packaging bag of the first embodiment, which allows each packaging bag 100 shown in Fig. 39 to be taken out separately, includes a box body 2 which accommodates therein multiple packaging bags 100 to orientate a second side portion 103 face up in the box and a bottom portion 101 face down in the box, a weight means 3 for restraining a square part of the packaging bag 100 accommodated in the box body 2, and an extended portion 4 formed to be projected from the box body 2 in the vicinity for placing a hand-slot portion 104 of the packaging bag 100 accommodated in the box body 2, in which the aforementioned members are made from various materials such as synthetic resin, paper and metal.
[0052] The box body 2 has a rectangular shaped opening portion 2A, having sufficient size for taking out the packaging bag 100, on the upper side of the box body 2, more definitely, the rectangular shaped opening portion 2A having a larger size than in the horizontal plain configuration of the packaging bag 100, in which the weight means 3 is equally provided at four corners of the opening portion 2A.
[0053] Each weight means 3 is formed to be a plate shape of a fan-shaped plane in Fig. 1 to Fig. 3, but, the shape is not intended to be limited to be the fan-shaped plane, and it can be shaped to be an alternative shape, for example, as shown in Figs. 4.
[0054] That is, the weight means 3 can be formed to be a curved shape oriented toward the center of the opening portion 2A as shown in Fig. 4A, to be a triangle as shown in Fig. 4B, to be a quadrilateral as shown in Fig. 4C, to be a L-shape as shown in Fig. 4D, to be a triangle formed with a window 3A inside the triangle, and to be rod-like as shown in Fig. 4F.
[0055] As shown in Fig. 3, the box body 2 has a support plate 5 for supporting the packaging bag 100 in the box body 2, in which multiple coil springs 6, as momentum means for building momenturn to cause the support plate 5 to move towards the upper side of the box body 2 (towards the opening portion 2A), are connectively provided between the support plate 5 and a bottom portion 2B of the box body 2. In the first embodiment, a spring such as a plate spring, a disk spring and so on or an elastic member such as rubber and the like can be used as the momentum means instead of the coil spring.
[0056] Incidentally, the support plate 5 and the momentum means (the coil spring 6) are not always needed to be provided in the first embodiment.
[0057] As shown in Fig. 1 to Fig. 3, the extended portion 4 is for placing the hand-slot portion 104 of the packaging bag 100, therefore, is formed to be a plate shape of a half-round plain on the same plain as the weight means 3.
[0058] The shape of the extended portion 4 can be formed as shown in Figs. 5 in the first embodiment. More specifically, the extended portion 4 can be formed to a shape which the end of the extended portion 4 slopes upward as shown in Fig.5A, to be a shape which the end of the extended portion 4 curves upward as shown in Fig. 5B, and to be a shape which a hole 4A is formed at the central portion of the extended portion 4 as shown in Fig. 5C.
[0059] Next, a method for taking out the packaging bag 100 by using the dispenser 1 for the packaging bag according to the first embodiment will be explained with reference to Fig. 6.
[0060] As shown in Fig. 6A, after the merchandise 105 is put on the top packaging bag 100 of the multiple packaging bags 100 accommodated in the box body 2, during this condition, both hand-slot portions 104 of the packaging bag 100 are opened to the right and left and lifted up until above the surface of the extended portions 4.
[0061] Even when the hand-slot portions 104 of the multiple packaging bags 100 are accidentally grasped, by lifting the top hand-slot portions 104 located on the extended portion 4 up until above the surface of the extended portions 4, only one packaging bag 100 can be drawn out to be pulled out from the weight means 3. Further, as shown in Fig. 6B, in the aforementioned condition, the merchandise 105 is packaged by lifting the hand-slot portions 104 upward
[0062] In consequence, in the first embodiment, ① the dispenser 1 for the packaging bag is structured by including the box body 2 which has thereon the opening portion 2A having sufficient size for taking out the packaging bag 100, and which accommodates therein the multiple packaging bags 100 to orientate the second side portion 103 face up in the box and the bottom portion 101 face down in the box, the weight means 3 which is provided to the opening portion 2 to press upon the packaging bag 100 accommodated in the box body 2, and the extended portion 4 which is formed adjacent to the position of the hand-slot portion 104 of the packaging bag 100 accommodated in the box body 2 to extend from the box body 2 to be capable of placing the hand-slot portion 104, therefore, by using the dispenser 1, each unique-shaped packaging bag 100 can be easily taken out separately, and simultaneously, the merchandise 105 can be packed in the bag in the state when each packaging bag 100 is taken out.
[0063] And, in the first embodiment, ② the box body 2 has therein the support plate 5 for supporting the packaging bag 100, in which the momentum means (the coil spring 6), for building momentum to cause the support plate 5 to move towards the upper side of the box body 2, is connectively provided between the support plate 5 and the bottom portion 2B of the box body 2, therefore, the packaging bag 100 supported with the support plate 5 by the coil spring 6 is forcibly moved towards the opening portion 2A, so that, even when the number of packaging bags 100 accommodated in the box body 2 becomes fewer, the top packaging bag 100 is positioned at the closest point to the opening portion 2A, therefore the packaging bag 100 can be smoothly taken out.
[0064] Further, ③ by providing the weight means 3 at the four corners of the rectangular shaped opening portion 2A, the packaging bag 100 is forced down with reliability, so that the packaging bag 100 does not accidentally fall away from the opening portion 2A during the conveyance of the dispenser 1.
[0065] In the first embodiment, as shown in Fig. 7 and Fig. 8, the dispenser for the packaging bag can be structured to include a sending roller 7. The sending roller 7 is rotatably provided at the end of a supporting arm 7A, fixed to the extended portion 4 at the basic end of the supporting arm 7A, in which the circumferential face of the sending roller 7 can be abutted to the hand-slot portion 104 of the packaging bag 100 accommodated in the box body 2 or adjacent to the hand-slot portion 104. The sending roller 7 rolls up the second side portion 103 provided with the hand-slot portion 104 by being rotated in the direction of an arrow P by a motor, hand or the like, and sends the hand-slot portion 104 or the vicinity of the hand-slot portion 104 out towards the extended portion 4.
[0066] Therefore, the first embodiment is structured to include the sending roller 7 which sends the hand-slot portion 104 of the packaging bag 100 in the box body 2 or the vicinity of the hand-slot portion 104 out towards the extended portion 4, so that the top packaging bag 100 of the packaging bags 100 accommodated in the box body 2 is securely sent out over the extended portion, with the result that only one packaging bag 100 can be taken out easily.
[0067] Further, in the first embodiment, the dispenser 1 for a packaging bag can be produced in a sequence shown in Figs. 9.
[0068] More specifically, as shown in Fig. 9A, a box 8 accommodating therein the multiple packaging bags 100 (omitted to illustrate in Fig. 9A) is formed with a perforated line 8A for bordering each outer area of a cover body 9, the box body 2, the weight means 3 and the extended portion 4. The box 8 is made from paper, and the perforated line 8A is a tear-off strip, V-notch or the like. As shown in Fig. 9B, the aforementioned perforated line 8A is cut and the opening portion 2A is formed to remove the lid portion 9 from the box 8, and further, as shown in Fig. 9C, the extended portion 4 located in the opening portion 2A is bent to project from the box body 2.
[0069] In the method for producing the dispenser 1 for a packaging bag in accordance to the aforementioned structure, ④ the dispenser 1 can be easily produced by only cutting the perforated line 8A structured with the tear-off strip or the like.
[0070] Next, a second embodiment according to the present invention will be explained with reference to Fig. 10 to Fig. 14.
[0071] Fig. 10 shows a perspective view of a dispenser for the packaging bag according to the second embodiment, and Fig. 11 shows a sectional view of the dispenser.
[0072] In the aforementioned drawings, the dispenser 11 for the packaging bag of the second embodiment, for which each packaging bag 100 shown in Fig. 39 is taken out separately, includes the box body 2, the weight means 3, and a recess portion 14 formed on the mutually faced sides of the box body 2, in which the box body 2 and the weight means 3 are made from various materials such as synthetic resin, paper and metal.
[0073] The box body 2, as well as in the first embodiment, includes therein the support plate 5 for supporting the packaging bag 100, in which multiple coil springs 6, causing the support plate 5 to move towards the upper side of the box body 2 (towards the opening portion 2A), are connectively provided between the support plate 5 and a bottom portion 2B of the box body 2 (see Fig. 11), but the support plate 5 and the coil spring 6 can be omitted.
[0074] The weight means 3 has, as shown in Fig. 10, not only a fan-shaped plate in the horizontal plain, but also other shapes as illustrated in Figs. 4.
[0075] The recess portion 14 has sufficient size for drawing out the hand-slot portion 104 of the packaging bag 100 accommodated in the box body 2 from the horizontal direction, in which is formed to be a rectangular shape in Fig. 10. The concrete shape of the recess portion 14, as a matter of course, has not only a rectangular shape but also, for example, a half-round shape as shown in Fig. 12A, and an oval shape as shown in Fig. 12B.
[0076] A method for taking out the packaging bag 100 by using the dispenser 1 for the packaging bag according to the second embodiment will be explained with reference to Figs. 13.
[0077] As shown in Fig. 13A, after the merchandise 105 is put on the top packaging bag 100 of multiple packaging bags 100 accommodated in the box body 2, during this condition, both hand-slot portions 104 of the packaging bag 100 are spread to the right and left toward the recess portion 14. In this condition, the end of the second side portion 103 is slightly exposed from the recess portion 14, so that only one packaging bag 100 can be separated from multiple packaging bags 100. Further, by drawing the hand-slot portion 104 upwards, one packaging bag 100 can be taken out to dislodge from the weight means 3, with the result that, as shown in Fig. 13B, during this condition, the merchandise 105 is packaged by drawing both hand-slot portions 104 upward.
[0078] In consequence, in the second embodiment, ① from the view of the structure of the dispenser 11 for the packaging bag, in which has the box body 2 having thereon the opening portion 2A opened to be of sufficient size for taking out the packaging bag 100 and accommodates therein multiple packaging bags 100 to orientate the second side portion 103 face up in the box and the bottom portion 101 face down in the box, the weight means 3 provided to the opening portion 2 to weigh upon the packaging bag 100 accommodated in the box body 2, and the recess portion 14 formed on the side face of the box body 2 in order to draw out the packaging bag 100 accommodated in the box body 2, by using the dispenser 11, the uniquely shaped packaging bag 100 can be easily taken out separately, and simultaneously, the merchandise 105 can be packed in the bag in the state when the packaging bag 100 is taken out.
[0080] Further, in the second embodiment, the dispenser 11 for a packaging bag can be produced in sequence as shown in Figs. 14.
[0081] More specifically, as shown in Fig. 14A, the box 8 accommodated therein multiple packaging bags 100 (omitted to illustrate in Fig. 14A) is formed with the perforated line 8A for bordering each range of a cover body 9, the box body 2, and the weight portion 3. The box 8 is made from paper, and the perforated line 8A is a tear-off strip. V-notch or the like. As shown in Fig. 14B, the aforementioned perforated line 8A is cut and the opening portion 2A and the recess portion 14 are formed to remove the lid portion 9 from the box 8.
[0082] In the method for producing the dispenser 11 for a packaging bag in accordance to the aforementioned structure as well as the first embodiment, ④ the dispenser 11 can be easily produced by only cutting the perforated line 8A structured with the tear-off strip or the like.
[0083] Next, a third embodiment according to the present invention will be explained with reference to Fig. 15 to Fig. 23.
[0084] Fig. 15 shows a perspective view of a dispenser for the packaging bag according to the second embodiment, and Fig. 16 shows a sectional view of the dispenser.
[0085] In the aforementioned drawings, the dispenser 21 for the paskaging bag of the third embodiment, which takes out each of the packaging bags 100 shown in Fig. 28 separately, includes the box body 2, a weight means 23 pressing in the vicinity of one of the hand-slot portions 104 of the packaging bag 100 accommodated in the box body 2 with a specified pressing force, and a recess portion 24 formed on the side face of the box body 2 in order to draw the other hand-slot portion 104 of the packaging bag 100 accommodated in the box body 2 out from the side face, in which the box body 2 is made from various materials such as synthetic resin, paper and metal.
[0086] The recess portion 24 is shaped to be a rectangle by cutting one side face of the box body 2 off to be continuously formed with the opening portion 2A.
[0087] The weight means 23 is composed of a coil spring 25, as a momentum means, fastened on the ceiling plate 2C of the box body 2 at the upper end of the coil spring 25, and a top member 26 provided at the lower end of the coil spring 25 to press in the vicinity of the hand-slot portion 104.
[0088] A method for taking out the packaging bag 100 by using the dispenser 21 for the packaging bag of the third embodiment will be interpreted based on Fig. 17.
[0089] The merchandise 105 is put on the upper-most packaging bag 100 of multiple packaging bags 100 accommodated in the box body 2, during this condition, the other hand-slot portion 104 of the packaging bag 100 is drawn out in the horizontal direction (the direction of an arrow Q). Half of the merchandise 105 becomes packaged with the packaging bag 100, and further, the other hand-slot portion 104 is continued to be drawn out in the horizontal direction, whereupon the vicinity of one of the hand-slot portions 103 of the packaging bag 100 is dislodged by opposing the pressing force of the coil spring 25 of the weight means 23, resulting in the packaging of the merchandise 105.
[0090] In consequence, according to the third embodiment, the dispenser 21 for the packaging bag is structured by including the box body 2 which has thereon the opening portion 2A opened to be of sufficient size for being capable of taking out the bag for the package 100, and which accommodates therein multiple packaging bags 100 to orientate the second side portion 103 face up in the box and the bottom portion 101 face down in the box, the weight means 23 which presses upon the vicinity of one of the hand-slot portions 104 of the packaging bag 100 accommodated in the box body 2 with the specified pressing force, and the recess portion 24 which is formed at the side face of the box body 2 in order to draw out the other hand-slot portion 104 of the packaging bag 100 accommodated in the box body 2, therefore, by using the dispenser 21, each uniquely shaped packaging bag 100 can be easily taken out separately, and simultaneously, the merchandise 105 can be packed in the bag in the same state the packaging bag 100 is taken out.
[0091] Further, in the third embodiment, the weight means 23 is structured to include the coil spring 25 fastened on the ceiling plate 2C of the box body 2 at the upper end of the coil spring 25, and the approximately conical-shaped top member 26 attached at the lower end of the coil spring 25 to weigh in the vicinity of the hand-slot portion 104, resulting in a simple structure for the weight means 23.
[0092] Incidentally, in the third embodiment, the weight means 23 is not intended to limit the component shown in Fig. 15 and Fig. 16. For example, the weight means 23 may be, as shown in Fig. 18, an elastic cylindrical member 27 provided to be upright on a bottom portion 2B of the box body 2 and pass through the hand-slot portion 104. The cylindrical member 27 retains one of the hand-slot portions 104 of the packaging bag 100 with a specified pressing force, therefore, as shown in Fig. 19, when the other hand-slot portion 104 is drawn out in the horizontal direction, the cylindrical member 27 is flexed (see an imaginary line),and then the vicinity of one of the hand-slot portions 103 of the packaging bag 100 is dislodged, resulting in the packaging of the merchandise 105.
[0093] In the third embodiment, as shown in Fig. 20, the box body 2 can have the same structure as the first embodiment to include therein the support plate 5 supporting the packaging bag 100, in which a multiple of coil springs 6, as momentum means for building momentum to cause the support plate 5 to move towards the upper side of the box body 2 (towards the opening portion 2A), are connectively provided between the support plate 5 and a bottom portion 2B of the box body 2. In this embodiment, the weight means 23 is composed of the support plate 5, the coil spring 6 and a weight member 26 fastened on the ceiling portion 2C of the box body 2.
[0094] In the dispenser 21 for the packaging bag of the aforementioned structure, as shown in Fig. 21, during the condition the merchandise 105 is put on the upper-most packaging bag 100, the other hand-slot portion 104 of the packaging bag 100 is drawn out in the horizontal direction, whereupon half of the merchandise 105 is packaged with the packaging bag 100 (see an imaginary line).
[0095] Therefore, in the embodiment shown in Fig. 20 and Fig. 21, the effect ② described in the first embodiment, and furthermore, the coil spring 25 as the weight means 25 can be omitted.
[0096] Further, in the third embodiment, as shown in Fig. 22, the box body 2 can be structured to include a slope member 28, sloping the other hand-slot portion 104 of the packaging bag 100, in the side provided with the recess portion 24.
[0097] In the dispenser 21 for the packaging bag of the aforementioned structure, as shown in Fig. 23, upon drawing the other hand-slot portion 104 of the packaging bag 100 out in the horizontal direction during the condition the merchandise 105 is put on the upper-most bag of the packaging bags 100, half of the merchandise 105 is to be packaged with the packaging bag 100 (see an imaginary line). Here, with drawing out the aforementioned packaging bag 100, another packaging bag 100 placed under the aforementioned packaging bag 100 is being drawn out together, but is stopped by the slope member 28.
[0098] Therefore, in the embodiment shown in Fig. 22 and Fig. 23, not only the slope member 28 allows the top packaging bag 100 to be smoothly drawn out, but also, when the packaging bag 100 is drawn out in the horizontal direction, another packaging bag 100 placed just under the packaging bag 100 does not move off.
[0099] And then, a fourth embodiment of the present invention will be interpreted with reference to Fig. 24 to Fig. 27.
[0100] Fig. 24 shows a perspective view when the dispenser for the packaging bag of the fourth embodiment is partially cut away.
[0101] In Fig. 24, the dispenser 31 for the packaging bag of the fourth embodiment is for taking out each of the packaging bags 100 shown in Fig. 28 separately, thereby it is composed of a box body 32 accommodating therein multiple packaging bags 100 to orientate the second side portion 103 face down in the box and the bottom portion 101 face up in the box, a first roller 33 delivering the upper-most packaging bag 100 of multiple packaging bags 100 accommodated in the box body 32 in the horizontal direction, a second roller 34 delivering the packaging bag 100 delivered by the first roller 33 in the upward direction, and a guide means 35 guiding the packaging bag 100 delivered by the second roller 34 to an opening groove 32A.
[0102] The box body 32 includes a rectangular bottom portion 32B, a first side portion 32C standing upright on the three edges of the bottom portion 32B, a second side portion 32D standing upright on another edge of the bottom portion 32B to have a higher height than the first side portion 32C, a first upper-most plate 32E fixed on the upper ends of the first side portion 32C, and a second upper-most plate 32F fixed on the upper end of the second side portion 32D, and is made of various materials such as synthetic resin, paper, metal or the like.
[0103] Between the first upper-most plate 32E and the second upper-most plate 32F, the opening groove 32A, having sufficient clearance for being able to pass one packaging bag 100, is formed to orientate in the horizontal direction.
[0104] The first roller 33 has a roller body 36 located along the direction of the shorter side of the box body 32 and a support arm 37 supporting both ends of the roller body 36, in which the roller body 36 can be rotated by hand, a motor or the like. The support arm 37 is provided with a coil spring 38 forcibly moving the roller body 36 toward the packaging bag 100, thereby the first roller 33 functions as the weight means for pressing the packaging bag 100. The upper end of the support arm 37 is fixed on the inner face of the first upper-most plate 32E.
[0105] The second roller 34 has a roller body 39 located in parallel with the first roller 33 and a support arm 40 supporting both ends of the roller body 39, in which the roller body 39 can be rotated by hand, a motor or the like. The end of the support arm 40 is fixed on the inner face of the second side portion 32D.
[0106] In the fourth embodiment, the number of rollers for delivering the packaging bag 100 is two, a first roller 33 and a second roller 34, but the number of rollers is not limited. The accuracy of delivering the packaging bag 100 is developed in proportion to the number of rollers, but, generally, in the case the dispenser 31 for the packaging bag is offered for a cheaper price, two or three rollers are sufficient.
[0107] The guide means 35 is an arcing curved surface 35A provided at the corner formed by the second side portion 32D and the second upper-most plate 32F. The structure of the guide means 35 is not limited to a structure shown in Fig. 24, for example, the guide means 35 can be formed as an oval curved surface 35B as shown in Fig. 25A, and can be formed as first and second guide rollers 35C and 36D which are respectively fixed on the inner surface of the first and second upper-most plates 32E and 32F.
[0108] The guide rollers 35C and 35D shown in Fig. 25B can be rotated by hand, a motor or the like. The first guide roller 35C and the second guide roller 35D are located to catch the packaging bag 100 between the first and second guide rollers, and the first guide roller 35C and the second roller 34 are located to catch the packaging bag 100 between the first guide roller and the second roller.
[0109] A method for taking out the packaging bag 100 by using the dispenser 31 for the packaging bag of the fourth embodiment will be explained below.
[0110] In the condition multiple packaging bags 100 are accommodated in the box body 32 to orientate the second side portion 103 face down in the box and the bottom portion 101 face up in the box, the first and second rollers 33 and 34 are operated to send the top packaging bag 100 in the box body 32 through the guide means 35 (35A, 35B, 35C, and 35D) to the opening groove 32A.
[0111] Each packaging bag 100 is separately sent from the opening groove 32A, and is sent out on the surface of the first upper-most plate 32E to be reversed between its front and back faces, namely, to orientate the second side portion 103 face up and the bottom portion 101 face down. The merchandise 105 is put on the packaging bag 100 in the state the packaging bag 100 is placed on the surface of the first upper-most plate 32E, in this state, both hand-slot portions 104 of the packaging bag 100 are extended to the right and left, resulting in the packageing of the merchandise.
[0112] In consequence, in the fourth embodiment, the dispenser 31 for the packaging bag is structured to include the box body 32 accommodating therein multiple packaging bags 100, the first roller 33 delivering the top packaging bag 100 of multiple packaging bags 100 accommodated in the box body 32 in the horizontal direction, the second roller 34 delivering the packaging bag 100 delivered from the first roller 33 in the upper vertical direction, and the guide means 35 for guiding the packaging bag 100 delivered from the second roller 34 to the opening groove 32A, therefore, by using this dispenser, each unique-shaped packaging bag 100 can be smoothly taken out separately.
[0113] Furthermore, the packaging bag 100 is accommodated in the box body 32 to orientate the second side portion 103 face down and the bottom portion 101 face up, so that the packaging bag 100, delivered from the first and second rollers 33 and 34 through the guide means 35, is reversed to the front and back, with the result that the merchandise can be packaged on the surface of the first upper-most plate 32E of the box body 32 in the condition when the packaging bag 100 is taken out.
[0114] Incidentally, in the fourth embodiment, as shown in Fig. 26, the box body 32 can be structured, as well as the first embodiment, to have the support plate 5 supporting the packaging bag 100 in the box, in which multiple coil springs 6, as momentum means for building momentum to cause the support plate 5 to move towards the upper side of the box 32 (towards the first roller 33), are connectively provided between the support plate 5 and a bottom portion 32B of the box body 32. In this structure, not only the effect ② described in the first embodiment can be obtained, but also the coil spring 6 can be omitted from the first roller 33.
[0115] As shown in Fig. 27, in the fourth embodiment, a sending roller 41 operated by hand, a motor or the like can be provided at a position adjacent to the opening groove 32A of the second upper-most plate 32F. In the aforementioned structure, the packaging bag 100 delivered to the guide means 35 can be accurately sent onto the surface of the first upper-most plate 32E.
[0116] And also, in the fourth embodiment, the packaging bag 100 may be accommodated in the box body 32 to orientate the second side portion 103 face up and the bottom portion 101 face down.
[0117] Next, a fifth embodiment according to the present invention will be explained below with reference to Fig. 28 to Fig. 33.
[0118] Fig. 28 is a perspective view showing a dispenser for a packaging bag of the fifth embodiment, Fig 29 is an expanded view showing a box body of the aforementioned dispenser for the packaging bag, Fig. 30 is a perspective view showing the aforementioned dispenser for the packaging bag in the process of being assembled, Fig. 31 is a perspective view showing a bag support body, which is prior to being assembled, accommodated in the aforementioned dispenser for the packaging bag, and Fig. 32 is a perspective view showing the used state of the aforementioned bag support body.
[0119] In these drawings, the dispenser 41 for the packaging hag of the fifth embodiment, which is for taking out each packaging bag 100 separately having the configuration as shown in Fig.39, is composed of the box body 42 and the bag support body 43 accommodated in the box body 42. The box body 42 and the bag support body 43 are made of, for example, hard paper materials, such as corrugate cardboard or the like, plastic having flexibility, or the like. The packaging bag 100 is made of a synthetic resin.
[0120] As shown in Fig. 29, the box body 42 before assembly is still like a one piece plate which is composed of an upper wall 44, a side wall 45, a bottom wall 46, and a back wall 47, in which tuck lines are formed on the lines that divide the aforementioned walls from one another.
[0121] Further, in the piled parts formed when the upper wall 44, the side wall 45, the bottom wall 46 and the back wall 47 are bent respectively, engagement portions 44A, 45A, 45B and 46A are respectively formed.
[0122] The above box body 42, as shown in Fig. 30, is assembled by bending the upper wall 44, the side walls 45, the bottom wall 46 and the back wall 47 along the tuck lines, and further, engaging the engagement portion 44A with the engagement 45A and the engagement portion 45B with the engagement portion 46A.
[0123] With assembling the box body 42, as shown in Fig. 28, a rectangular opening portion 48 is formed on the front side, that is one wall face of the vertical side, of the box body 42. The opening portion 48 has greater width than the packaging bag 100, in which, at least, the edge of one side of the packaging bag 100 accommodated in the box body 42 is exposed from the opening portion 48.
[0124] The box body 42 is placed in the state in which the opening portion 48 is oriented in the horizontal direction, therefore, the box body 42 can be placed on a workbench or the like independently.
[0125] The aforementioned "independence" means both states in which the box body 42 stands on the workbench or the like by itself and the box body 42 stands by hanging on hooks provided on the wall or the like. In order to stand the box body 42 by itself on the workbench or the like, the bottom face of the box body 42 is wider, and in order to hang the box body 42 on the hooks provided on the wall or the like, attachment holes 47C are formed on the upper side of the back wall 47.
[0126] In Fig. 31, the bag support body 43 as well as the aforementioned box body 42 is plate-like formed with tuck lines on the lines that divide each portion from one another before being assembled. Two engagement tabs 49 are formed on the part going to be the bottom face of the bag support body 43, and further, on the side wall opposite from the side formed with the engagement tabs 49, first engagement portions 43A and second engagement portions 43B are forrned to be inserted therein with the engagement tabs 49 when the bag support body 43 is assembled.
[0127] The aforementioned bag support body 43 is assembled by folding down each plate-like portion, folding back the engagement tag 49 after the engagement tag 49 is inserted into the first engagement portion 43A, and inserting the end of the engagement tag 49 into the second engagement portion 43B, by forming a pedestal having an approximate isosceles triangle pillar (see Fig. 32).
[0128] Incidentally, it is desirable for the bottom face of the bag support body 43 to be formed to the same shape as the bottom face of the box body 42 (see Fig. 33B). In the aforementioned structure, the bag support body 43 is prevented from moving in the box body 42 and rattling.
[0129] The following will describe as to the accommodating movement in which the packaging bag 100 on the bag support body 43 is accommodated into the box body 42 with reference to Figs. 33A and 33B.
[0130] Figs. 33A and 33B are explanatory views showing a sequence of the accommodating movements of the bag support body.
[0131] As shown in Fig. 33A, when the bag support body 43 is accommodated into the box body 42, the engagement between the engagement portion 44A and 45A of the box body 42 is released to open the upper wall 44. The bag support body 43 set with the packaging bag 100 is put into the box body 42 from the upper side of the opening portion 48.
[0132] As shown in Fig. 33B, the bottom face of the bag support body 43 is set on the bottom face of the box body 42, the engagement portions 44A and 45A of the box body 42 are engaged, and further, the upper wall 44 is closed.
[0133] Incidentally, it is considered, as other accommodating method of the bag support body 43, to put the bag support body 43 into the box body 42 from the lower side of the opening portion 48 after the bottom wall 46 is opened or to put the bag support body 43 into the box body 42 by opening the side wall 45.
[0134] According to the dispenser 41 for the packaging bag of the fifth embodiment having the structure as described thus far, as shown in Fig. 28, the edge of one side of each synthetic resin made packaging bag 100 exposed from the opening portion 48 can be easily picked up with fingers by separating separately, with the result that each slippery synthetic resin made packaging bag 100 can be certainly and smoothly taken out from the box body 42 separately.
[0135] The opening portion 48 for taking out the packaging bag 100 is formed on the front side, that is one wall surface of the vertical side, of the box body 42, thereby dust and the like has difficulty entering the inside of the box body 42, resulting in the maintenance of the hygienic condition of the packaging bag 100 accommodated in the box body 42.
[0136] Furthermore, for the difficult entry of dust and the like into the opening portion 48, the opening portion 48 can be formed with a larger size, resulting in the packaging bag 100 being taken out with ease.
[0137] While the bag support bodies 43 are exchanged, a part of the box body 42 can be retained to attach to the box body 42, therefore, the box body 42 does not need to have a space for placing, and further, the packaging bag 100 can be refilled into the box body 42 with both hands, with the result that the packaging bag 100 can be smoothly refilled.
[0138] The box body 42 is structured to be the independent type, that is, the box body 42 is placed in the upright state in which the opening portion 48 is oriented in the horizontal direction, whereby the space for putting the dispenser 41 can be narrower, with the result that the work area for packing in a kitchen or at a checkout counter can be widely occupied for working.
[0139] Incidentally, the opening portion 48 formed on the box body 42 is not intended to be limited as shown in Fig. 28, therefore, by changing the configurations, sizes and positions, the acting effect differing from the fifth embodiment can be obtained. In the following sixth to eighth embodiments, the changed instances of the opening portion will be explained.
[0140] The sixth embodiment according to the present invention will be explained below with reference to Fig. 34.
[0141] Fig. 34 is a perspective view showing the dispenser 51 for the packaging bag according to the second embodiment.
[0142] In the drawing, the dispenser 51 of the fifth embodiment is almost the same structure as the dispenser 41 of the fifth embodiment, but the different point from the dispenser 41 of the fifth embodiment is that an opening portion 58, having a configuration to expose the edge area of the lower side of the synthetic resin made packaging bag 100, is formed on the front wall of a box body 52.
[0143] The opening portion 58 is formed to be as small as possible within the range the packaging bag 100 can be smoothly taken out.
[0144] According to the aforementioned structure, the edge of the lower side of each synthetic resin made packaging bag 100 exposed from the opening portion 58 can be easily picked up by separating individually with fingers, naturally, the synthetic resin made packaging bag 100 can be certainly and smoothly taken out from the box body 52. Furthermore, the opening portion 58 is formed to be smaller, whereby it can prevent the entry of dust with reliability.
[0145] Incidentally, the opening portion 58 is not intended to be limited to the forming of the exposed edge of the lower side of the synthetic resin made packaging bag 100, and, as illustrated with an imaginary line in the drawing, the edge of one lateral side or the edges of both lateral sides of the synthetic resin made packaging bag 100 may be exposed. Otherwise it can be structured to open two or all three of the aforementioned opening portions.
[0146] The seventh embodiment according to the present invention will be explained below with reference to Fig. 35.
[0147] Fig. 35 is a perspective view showing the dispenser 61 for the packaging bag according to the seventh embodiment.
[0148] In the drawing, the dispenser 61 for the packaging bag is almost the same structure as the dispenser 41 of the fifth embodiment, but the only difference from the dispenser 41 of the fifth embodiment is that an opening portion 68 of a hook type, having a configuration to expose the edges of the two intersecting sides of the synthetic resin made packaging bag 100, on the front side of a case body 62.
[0149] According to the aforementioned structure, the edges of the two intersecting sides of each synthetic resin made packaging bag 100 can be easily picked up by separating separately with fingers, with the result that each synthetic resin made packaging bag 100 can be certainly and smoothly taken out from the case body 62 separately.
[0150] The eighth embodiment according to the present invention will be explained below with reference to Fig. 36.
[0151] Fig. 36 is a perspective view showing the dispenser 71 for the packaging bag according to the eighth embodiment.
[0152] In the drawing, the dispenser 71 for the packaging bag is almost the same structure as the dispenser 41 of the fifth embodiment, but the only difference from the dispenser 41 of the fifth embodiment is that an opening portion 78 is formed on the central part of the front wall of a box body 72.
[0153] The opening portion 78 is formed to expose the folded portion of the first side portion 102 and the second side portion 103 of the synthetic resin made packaging bag 100, in which is formed to be as small as possible within the range the packaging bag 100 can be smoothly taken out.
[0154] According to the structure as described thus far, by hooking the folded part of the synthetic resin made packaging bag 100 with fingers, the folded part can be easily pinched, with the result that the synthetic resin made packaging bag 100 can be easily and securely taken out from the box body 72.
[0155] For the capability of easily taking out the synthetic resin made packaging bag 100, the opening portion 78 is formed as small as possible, therefore, dust or the like is hindered from entering the inside of the box body 72.
[0156] Incidentally, the fifth embodiment to the seventh embodiment are not limited to the structures as described above.
[0157] For example, as shown in Fig. 37, in the dispenser 51 of the fifth embodiment, having the opening portion 48 on the central front face of the box body 42, the synthetic resin made packaging bag 100 can be easily taken out by pinching the folded portion of the synthetic resin made packaging bag 100 with fingers.
[0158] The configurations of the opening portions 48, 58, 68 and 78 of the box bodies 42, 52, 62 and 72 are not limited to each aforementioned embodiment, and it can be changed to another configuration if any one of the edge portions, around the two intersecting sides, or the folded portion of the synthetic resin made packaging bag 100 is exposed.
