CONTENT CONTAINER

Abstract

 Provided is a content container according to an embodiment of the present invention. The content container comprises: a container body which has an accommodation space for storing contents formed therein and which is pressed by an external force; a discharge portion of which the upper end is open so as to discharge the contents according to pressure applied to the container body; and a shoulder portion which extends from the circumference of the lower end of the discharge portion and connects the discharge portion and the container body, wherein a deformation suppression groove which suppresses deformation of the discharge portion when the container body is pressed may be recessed in at least one area of the shoulder portion.

Description

Technical Field

[0001] The present invention relates to a container, more specifically to a container that is capable of effectively suppressing a discharge part from being deformed in shape.

Background Art

[0002] As shown in FIG. 1, a conventional tube consists of a soft tube body 11 for storing a content therein, a discharge part 12 open on top thereof to discharge the content stored in the tube body 11 therethrough, and a shoulder part 13 extending from the lower end periphery of the discharge part 12 to connect the tube body 11 and the discharge part 12. Even if not shown in FIG. 1, a cap or nozzle having a discharge hole is coupled to the discharge part 12.

[0003] If the outer periphery of the tube body 11 of the tube is pressed by a user, an internal pressure of the tube body 11 increases to allow the content stored in the tube body 11 to be discharged through the discharge part 12 or the cap connected to the discharge part 12 to the outside.

[0004] However, as shown in FIG. 2, as the tube body 11 of the tube is pressed, the force generated from the pressing is transferred to the discharge part 12 through the shoulder part 13 so that the discharge part 12 becomes deformed to an oval shape from a circular shape, thereby causing the content to leak between the discharge part 12 and the cap coupled to the discharge part 12.

[0005] Therefore, there is a need to develop a new container capable of effectively suppressing a discharge part from being deformed in shape.

[0024] FIG. 3 is a sectional view showing a container according to an embodiment of the present invention, FIG. 4 is an enlarged view showing a portion 'A' of FIG. 3, and FIG. 5 is a perspective view showing the container according to the embodiment of the present invention.

[0025] Referring to FIGs. 3 to 5, a container 1000 according to an embodiment of the present invention largely includes a container body 100, a discharge part 200, and a shoulder part 300.

[0026] The container body 100 has an accommodation space formed at the inside thereof to store a given content. The container body 100 has the shape of a tube open on top thereof and sealed on bottom thereof, but without being limited thereto, the container body 100 may have various shapes reduced in volume when pressed, such as soft bottles, tottles, and the like.

[0027] According to the embodiment of the present invention, the container body 100 has at least a portion made of a soft material. If the outer periphery of the container body 100 is pressed by an external force applied by a user, the container body 100 is deformed (that is, compressed) in shape to allow the content stored therein to be discharged to the outside through the discharge part 200.

[0028] In this case, the content is, for example, a liquid or gel cosmetic content, a drug, a quasi-drug, etc. For example, the content may be lotion, milk lotion, moisture lotion, nutrition lotion, skin lotion, skin softer, skin toner, astringent, massage cream, nutrition cream, whitening essence, tone-up cream, sunblock, sun cream, sun milk, BB cream, base, foundation, CC cream, concealer, blusher, shade, eyeshadow, eyebrow, eye cream, primer, etc. However, the content may not be limited thereto, and therefore, the content may include various types of materials that are stored in the container body 100 and thus discharged to the outside when the container body 100 is pressed.

[0029] The discharge part 200 is disposed on top of the container body 100 in such a way as to communicate with the container body 100 and serves to discharge the content to the outside through an open top thereof.

[0030] According to the embodiment of the present invention, the discharge part 200 is coupled to a cap or nozzle having a discharge hole, a pump, or the like. To do this, the discharge part 200 has at least one coupling portion formed on the outer peripheral surface thereof. For example, the coupling portion is a screw thread, a coupling protrusion, a coupling groove, or the like, but without being limited thereto, a variety of coupling portions may be formed on the discharge part 200.

[0031] The shoulder part 300 extends downward from the outer periphery of the lower end portion of the discharge part 200 at a given inclination in an outward direction in such a way as to connect the container body 100 and the discharge part 200. At least a portion of the upper end portion of the container body 100 is sealed with the should part 300.

[0032] The shoulder part 300 has a given thickness and is made of a synthetic resin harder than the container body 100.

[0033] According to the embodiment of the present invention, the lower end portion of the shoulder part 300 is coupled to the upper end portion of the container body 100 by means of various methods such as thermal adhesion, ultrasonic adhesion, adhesion using an adhesive, double injection molding, and the like.

[0034] According to the embodiment of the present invention, some of the container body 100, the discharge part 200, and the shoulder part 300 may be formed unitarily with each other by means of injection molding. For example, the discharge part 200 and the shoulder part 300 may be formed unitarily with each other by means of injection molding, and next, they are coupled to the upper end portion of the container body 100 by means of adhesion.

[0035] The shoulder part 300 has a deformation suppression groove 310 as an inward concave formed on at least a given area thereof. The deformation suppression groove 310 serves to suppress the discharge part 200 from being deformed in shape when the container body 100 is pressed to discharge the content therefrom. When the container body 100 is pressed, in detail, at least a given area of the deformation suppression groove 310 is contracted or expanded to allow the width of the deformation suppression groove 310 to be changed in size, so that the deformation force caused by the pressing of the container body 100 is prevented from being transferred to the discharge part 200 through the shoulder part 300, thereby suppressing the discharge part 200 from being deformed in shape. According to the embodiment of the present invention, a maximum depth of the deformation suppression groove 310 is in the range between 0.8 and 2 mm, and a portion of the shoulder part 300, on which the deformation suppression groove 310 is formed, has a thickness in the range between 0.5 and 1.0 mm.

[0036] The deformation suppression groove 310 is formed spaced apart from a connection portion between the discharge part 200 and/or the shoulder part 300 and the container body 100 by a given distance. For example, the deformation suppression groove 310 has the shape of a circle and is spaced apart from the lower end portion of the discharge part 200 in such a way as to surround the outer periphery of the lower end portion of the discharge part 200. According to the embodiment of the present invention, the deformation suppression groove 310 is formed at a position distant inward by 3 to 10 mm from the connection portion between the shoulder part 300 and the container body 100.

[0037] To form the deformation suppression groove 310, the shoulder part 300 includes a first bent portion 320, a second bent portion 330, and a third bent portion 330. The first bent portion 320, the second bent portion 330, and the third bent portion 330 of the shoulder part 300 are formed sequentially from the outer periphery of the lower end portion of the discharge part 200, and as the shoulder part 300 is bent around the first to third bent portions 320 to 340 at given curvatures, the deformation suppression groove 310 is formed. For example, the deformation suppression groove 310 is formed by locating the second bent portion 330 between the first bent portion 320 and the third bent portion 340 so that the second bent portion 330 forms a valley (that is, a point with a maximum depth).

[0038] According to the embodiment of the present invention, a first slant surface 311 and a second slant surface 312 are formed on the inside of the deformation suppression groove 310. For example, the first slant surface 311 and the second slant surface 312 are located on both sides of the second bent portion 330 in such a way as to extend to the first bent portion 320 and the third bent portion 340. As a result, the deformation suppression groove 310 has the sectional shape of "V". In a state where the container body 100 is not pressed, an angle between the first slant surface 311 and the second slant surface 312 is in the range between 60 and 120°.

[0039] The container 1000 as shown in FIGs. 3 to 5 is just exemplary in shape, and therefore, the container 1000 may have various shapes according to embodiments of the present invention. According to the embodiments of the present invention, further, the container 100 may have additional parts such as a cap, a nozzle, and the like as well as the container body 100, the discharge part 200, and the shoulder part 300 as mentioned above.

Experimental example - Deformation experiments through pressing of the container body

[0040] As shown in FIG. 6, the shoulder part having the deformation suppression groove and the discharge part according to the present invention were made (See FIG. 6a), and a shoulder part having a plurality of reinforcing ribs and a discharge part were made (See FIG. 6b). In this case, the reinforcing ribs served to support the outer periphery of the discharge part and suppress the discharge part from being deformed in shape.

[0041] Next, the container with the shoulder part and the discharge part according to the present invention was made (in a first embodiment of the present invention), and a container with the shoulder part having the plurality of reinforcing ribs and the discharge part was made (in a first comparison example). After that, deformation experiments for both containers were carried out.

[0042] Referring first to FIG. 7, caps were coupled to the discharge parts of the containers in the first embodiment of the present invention and the first comparison example, and if the container bodies of the containers were pressed, the width of the deformation suppression groove corresponding to the pressed position of the container body of the container in the first embodiment of the present invention was varied to allow the shoulder part to be substantially spaced apart from the cap (See FIG. 7a). However, a gap between the shoulder part and the cap of the container in the first comparison example was small (See FIG. 7b).

[0043] Referring next to FIG. 8 and Table 1, if the container bodies of the containers in the first embodiment of the present invention and the first comparison example were pressed, the discharge part of the container in the first embodiment of the present invention was kept in the shape of a circle (See FIG. 8a), but the discharge part of the container in the first comparison example was deformed to the shape of an oval (See FIG. 8b).

Table 1

	Maximum width of discharge part prior to pressing the container body	Maximum width of discharge part after the container body is pressed	Degree of deformation
First embodiment of the present invention	15.78 mm	15.99 mm	0.21 mm
First comparison example	15.75 mm	16.40 mm	0.65 mm

[0044] It can be appreciated from Table 1 that in the case of the embodiment where the deformation suppression groove is formed on the shoulder part, the force (deformation force) generated when the container body is pressed changes the width of the deformation suppression groove, without being transferred to the discharge part, so that the discharge part is effectively prevented from being deformed in shape.

[0045] As mentioned above, the preferred embodiment of the present invention has been disclosed in the specification and drawings. Therefore, persons skilled in the relevant art can appreciate that many modifications and variations are possible in light of the above teachings. It is therefore intended that the scope of the invention be limited not by this detailed description, but rather by the claims appended hereto.
