Description

Field of the Invention

[0001] The present invention relates to a cap unit and a container with a cap.

Description of the Prior Art

[0002] Conventionally, there is a container with a cap that includes a cap unit, the cap unit being detachably attached to a container main body whose upper portion is open (see, for example, Patent document 1 below).

[0003] The cap unit includes: a cap main body, which blocks an upper opening of the container main body and in which a liquid passage port and a gas passage port communicated with the inner side of the container main body are arranged in the upper portion; a lid body, which is pivotably attached to the cap main body via a hinge part; and a lid packing, which is detachably attached to the inner side of the lid body and in which a liquid passage plug part that blocks the liquid passage port and a gas passage plug part that blocks the gas passage port are arranged.

[0004] In addition, the cap unit includes a lid locking mechanism that fixes the lid body, which is urged in a direction of opening the liquid passage port and the gas passage port by an urging member arranged in the hinge part, to the cap main body in a position where the liquid passage plug part and the gas passage plug part block the liquid passage port and the gas passage port.

[0005] In the container with a cap that includes this kind of cap unit, by releasing the fixation of the lid body performed by the lid locking mechanism, the lid body pivots due to the urging of the urging member, and the liquid passage port and the gas passage port come into an open state. Accordingly, it becomes possible to drink or pour the beverage in the container main body.

[0006] Japanese Patent Publication No. 2023-22743 discloses a cap unit that is rotatably connected to a cap body via a hinge, and has a liquid passage port that closes the upper opening of the container body and communicates between the inside and the outside of the container body, and the liquid passage port. Locking means for fixing (locking) the lid in the closed position with respect to the cap body are provided. The hinge connects the rear end of the cap body and the rear end of the lid, and the lock means fixes the front end of the cap body and the front end of the lid.

Summary of the Invention

[0007] In the container with a cap that includes the conventional cap unit described above, when the beverage in the container main body is drunk, the pressure in the container main body temporarily becomes negative as the volume of the beverage in the container main body decreases. At this time, external air is introduced into the interior of the container main body through the gas passage port arranged in the upper portion of the cap main body. Accordingly, the pressure in the container main body returns to atmospheric pressure, and thus it is possible for the beverage to flow out stably from the liquid passage port.

[0008] On the other hand, in order to prevent the beverage in the container main body described above from leaking to the outside from the liquid passage port and the gas passage port, when the lid body blocks the upper portion of the cap main body, the liquid passage port and the gas passage port are blocked by the liquid passage plug part and the gas passage plug part of the lid packing.

[0009] In addition, since the gas passage port has a smaller opening area than the liquid passage port, a sealing part is arranged on the upper surface of the cap main body, and the gas passage port in the center of the sealing part is blocked by the gas passage plug part which is in close contact with the sealing part.

[0010] However, in the conventional cap unit, the distance between the liquid passage port and the gas passage port on the upper surface of the cap main body is different depending on the size of the container main body. For this reason, the current situation is that in order to block the liquid passage port and the gas passage port under optimal conditions for each size of the container main body, it is necessary to prepare lid packings with different distances between the liquid passage plug part and the gas passage plug part, and component sharing is not made.

[0011] In addition, in the conventional cap unit, the sealing part with the gas passage port arranged in the center is arranged in a manner of protruding upward, and the plate thickness thereof is thinner than the surrounding region. For this reason, during the molding of the cap unit made of resin, the fluidity of the resin may become poor, and it may not be possible to mold the sealing part to the intended shape.

[0012] The present invention is proposed in view of these conventional circumstances, and aims to provide a cap unit that makes it possible to stabilize the dimensions or moldability of a sealing part and appropriately block a liquid passage port and a gas passage port by a lid packing while striving for the sharing of the lid packing, and a container with a cap that makes it possible to further improve the usability by including that kind of cap unit.

[0013] In order to achieve the above aim, the present invention provides the following means.

[1] A cap unit, which is detachably attached to a container main body whose upper portion is open, the cap unit including:

a cap main body, which blocks an upper opening of the container main body and in which a liquid passage port and a gas passage port communicated with the inner side of the container main body are arranged;

Description of the embodiments

[0016] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
First, as a first embodiment of the present invention, for example, a container with a cap 100A that includes a cap unit 1A shown in FIG. 1 and FIG. 2 will be described.

[0017] Note that FIG. 1 is a cross-sectional view showing a state where a lid body 9 is blocked in the container with a cap 100A that includes the cap unit 1A. FIG. 2 is a perspective view showing a state where a liquid passage port 10 and a gas passage port 11 of the cap unit 1A are open.

[0018] As shown in FIG. 1 and FIG. 2, the container with a cap 100A of the embodiment includes the cap unit 1A of the embodiment and a container main body 2A to which the cap unit 1A is detachably attached.

[0019] The container with a cap 100A is a container for beverages that can keep the beverage (liquid) accommodated in the container main body 2A hot or cold by the container main body 2A having a vacuum heat insulation structure.

[0020] Specifically, the container main body 2A is configured by a container having a double structure, which has a bottomed tubular outer container 3 and an inner container 4 made of, for example, stainless steel or the like, and in which mouth portions of the outer container 3 and the inner container 4 are joined in a state where the inner container 4 is accommodated on the inner side of the outer container 3.

[0021] In addition, a vacuum heat insulation layer 5 is arranged between the outer container 3 and the inner container 4. The vacuum heat insulation layer 5 can be formed by, for example, blocking a degassing hole arranged on the bottom surface of the outer container 3 in a chamber decompressed (evacuated) to a high vacuum.

[0022] The container main body 2A has a substantially circular bottom portion 2a, a body portion 2b that rises into a substantially cylindrical shape from the outer periphery of the bottom portion 2a, and a substantially cylindrical mouth-neck portion 2c whose diameter is reduced on the upper side of the body portion 2b.

[0023] The upper end portion of the mouth-neck portion 2c is open in a circular shape as an upper opening 2d of the container main body 2A. In addition, the inner peripheral surface of the mouth-neck portion 2c has a smaller diameter than the inner peripheral surface of the body portion 2b. In addition, a male screw part 6 is arranged on the outer peripheral surface of the mouth-neck portion 2c.

[0024] Note that although the container with a cap 100A of the embodiment has a substantially cylindrical appearance shape as a whole, the appearance shape of the container with a cap 100A is not particularly limited, and it is possible to make appropriate changes according to the size, design, or the like. In addition, painting, printing, or the like may be performed on the outer peripheral surface of the container main body 2A.

[0025] The cap unit 1A of the embodiment includes: a cap main body 7, which blocks the upper opening 2d of the container main body 2A described above; and the lid body 9, which is pivotably attached to the cap main body 7 via a first hinge part 8.

[0026] Note that in the following description, the side on which the lid body 9 is attached to the cap main body 7 via the first hinge part 8 is described as the "rear side (back surface side)" of the cap unit 1A (the container with a cap 100A), and the side opposite to the above-described side is described as the "front side (front surface side)" of the cap unit 1A (the container with a cap 100A).

[0027] The cap main body 7 is made of, for example, a heat-resistant resin, and has: a peripheral wall portion 7a, which is formed in a substantially cylindrical shape in a manner of being continuous with the body portion 2b of the container main body 2A and covers the outer periphery side over the entire circumference; an upper wall portion 7b, which covers the upper portion of the peripheral wall portion 7a and in which the liquid passage port 10 and the gas passage port 11 communicated with the inner side of the container main body 2A are arranged; and an inner wall portion 7c, which protrudes in a substantially cylindrical shape from the lower surface of the upper wall portion 7b in a manner of being fitted into the inner side of the container main body 2A from the upper opening 2d.

[0028] A female screw part 12, which is screwed to the male screw part 6 on the container main body 2A side, is arranged on the inner peripheral surface of the peripheral wall portion 7a. Accordingly, the cap main body 7 is detachably attached to the outer side of the mouth-neck portion 2c by screwing in a state of covering the upper opening 2d of the container main body 2A.

[0029] The liquid passage port 10 is configured by a nozzle part, which is located in a position in the upper wall portion 7b closer to the front side than the first hinge part 8 and protrudes upward in a substantially cylindrical shape in a state of penetrating the upper wall portion 7b in a vertical direction.

[0030] The gas passage port 11 is configured by a circular hole portion, which is located between the liquid passage port 10 of the upper wall portion 7b and the first hinge part 8 and penetrates the upper wall portion 7b in the vertical direction. The gas passage port 11 has a smaller opening area than the liquid passage port 10.

[0031] A water-stopping packing 13 is detachably attached to the lower surface on the inner side of the cap main body 7. The water-stopping packing 13 is a sealing member for making a seal (stopping water) between the container main body 2A and the cap main body 7, and consists of an elastic member such as heat-resistant rubber (such as silicone rubber) or elastomer, for example.

[0032] The water-stopping packing 13 has a stepped shape along the lower surface of the upper wall portion 7b, the outer peripheral surface and the lower end surface of the inner wall portion 7c, and is formed in a circular ring shape as a whole. The water-stopping packing 13 is fitted to the lower surface on the inner side of the cap main body 7 in a state of covering the cap main body 7 from below, while the water-stopping packing 13 is in contact with the lower surface of the upper wall portion 7b and the outer peripheral surface of the inner wall portion 7c and is slightly spaced from the lower end surface of the inner wall portion 7c.

[0033] On the other hand, the water-stopping packing 13 can be removed from the lower surface on the inner side of the cap main body 7 by elastically deforming (stretching) itself. Accordingly, the water-stopping packing 13 and the cap main body 7 can be washed separately, and it is possible to keep the space between the water-stopping packing 13 and the cap main body 7 sanitary.

[0034] In addition, an elastic flange portion 13a protruding over the entire circumference in a diameter-increasing direction is arranged at the upper end portion of the water-stopping packing 13. When the cap main body 7 is attached to the container main body 2A, the water stopping packing 13 comes into a state where the upper surface side is in close contact with the lower surface of the upper wall portion 7b over the entire circumference and the lower surface side is in close contact with the upper end portion of the mouth-neck portion 2c over the entire circumference, while the elastic flange portion 13a elastically deforms. Accordingly, it is possible to make a seal (stop water) between the cap main body 7 and the container main body 2A in a liquid-tight manner.

[0035] The lid body 9 is made of, for example, a heat-resistant resin, and has: a peripheral wall portion 9a, which is formed in a substantially cylindrical shape in a manner of being continuous with the peripheral wall portion 7a of the cap main body 7 (the outer peripheral surface of the cap main body 7); and a top wall portion 9b, which covers the top surface of the peripheral wall portion 9a.

[0036] The first hinge part 8 is located at the rear end portion between the peripheral wall portion 7a and the upper wall portion 7b of the cap main body 7. The lid body 9 is attached via the first hinge part 8 in a manner of pivoting freely between a position of blocking the liquid passage port 10 and the gas passage port 11 (hereinafter referred to as "blocking position") and a position of opening the liquid passage port 10 and the gas passage port 11 (hereinafter referred to as "opening position").

[0037] A lid packing 14 is located at and detachably attached to the lower surface on the inner side of the lid body 9. The lid packing 14 is a sealing member for making a seal between the cap main body 7 and the lid body 9, and consists of an elastic member made of the same material as the water-stopping packing 13 described above.

[0038] The lid packing 14 has a liquid passage plug part 14a that blocks the liquid passage port 10, and a gas passage plug part 14b that blocks the gas passage port 11.

[0039] The liquid passage plug part 14a is arranged in a manner of protruding downward from the lower surface on the front side of the lid packing 14 in a dome shape. The gas passage plug part 14b is arranged in a manner of protruding downward from the lower surface on the rear side of the lid packing 14 in a bottomed long cylindrical shape.

[0040] In addition, the lid packing 14 has a fitting protrusion 14c which is fitted into a hole portion 9c arranged in the lid body 9, and a gas passage fitting part 14d into which a tubular wall portion 9d arranged in the lid body 9 is fitted.

[0041] The hole portion 9c is arranged in a manner of penetrating the front side of the top wall portion 9b in the vertical direction in a substantially cylindrical shape. The fitting protrusion 14c is arranged in a manner of protruding upward from the upper surface on the side opposite to the liquid passage plug part 14a on the front side of the lid packing 14 in a substantially cylindrical shape. The tubular wall portion 9d is arranged in a manner of protruding downward from the lower surface on the rear side of the top wall portion 9b in a long cylindrical shape. The gas passage fitting part 14d is arranged in a manner of protruding upward from the upper surface on the side opposite to the gas passage plug part 14b on the rear side of the lid packing 14 so as to recess the inner side of the gas passage plug part 14b.

[0042] The lid packing 14 is attached to the lower surface on the inner side of the lid body 9 in a state where the fitting protrusion 14c is fitted into the hole portion 9c and the tubular wall portion 9d is fitted into the gas passage fitting part 14d. Note that although the above-described configuration in which the tubular wall portion 9d is fitted into the inner side of the gas passage fitting part 14d is used in the embodiment, a configuration in which the gas passage fitting part 14d is fitted into the inner side of the tubular wall portion 9d may alternatively be used. That is, it is sufficient if the lid body 9 and the lid packing 14 are integrated by fitting.

[0043] Here, the fitting protrusion 14c can be visually observed from the upper surface side of the lid body 9 even when the lid body 9 is in the blocking position. Accordingly, it is possible to visually confirm that the lid packing 14 is attached to the lid body 9, not only when the lid body 9 is in the opening position, so that the lid packing 14 will not be forgotten to be attached.

[0044] On the other hand, by removing the lid packing 14 from the lower surface on the inner side of the lid body 9, the lid packing 14 and the lid body 9 can be washed separately, and it is possible to keep the space between the lid packing 14 and the lid body 9 sanitary.

[0045] Note that although the above-described configuration in which the lid packing 14 is detachably attached to the lid body 9 is used, it is not limited to this configuration, and a configuration in which the lid packing 14 is integrally attached to the lid body 9 may alternatively be used, for example. In this case, by integrating the lid body 9 and the lid packing 14 with no gap therebetween, no water or the like will enter the space between the lid packing 14 and the lid body 9, and it is possible to keep the space sanitary.

[0046] In the cap unit 1A of the embodiment, when the lid body 9 blocks the upper portion of the cap main body 7, the liquid passage plug part 14a blocks the liquid passage port 10 in a state of being in close contact with the surrounding region on the upper side of the liquid passage port 10 while elastically deforming, and the gas passage plug part 14b blocks the gas passage port 11 in a state of being in close contact with the surrounding region of the gas passage port 11 (sealing part) while elastically deforming. Accordingly, it is possible to make a seal between the cap main body 7 and the lid body 9 via the lid packing 14.

[0047] As shown in FIG. 1 and FIG. 2, the cap main body 7 has: a sealing surface 7d, which is a sealing part being in close contact with the lower surface of the gas passage plug part 14b in a state where the gas passage plug part 14b blocks the gas passage port 11; and a gas passage protrusion 7e, which protrudes upward from the upper surface of the upper wall portion 7b (the cap main body 7) with the diameter being reduced. The gas passage protrusion 7e has an oval shape that extends in a front-rear direction in a planar view. The sealing surface 7d is configured as a flat surface having an oval shape that extends in the front-rear direction in a planar view on the upper surface of the gas passage protrusion 7e.

[0048] The sealing surface 7d and the gas passage protrusion 7e are arranged in manner of protruding above the upper wall portion 7b so that the plate thickness of a part of the cap main body 7 increases. For this reason, the fluidity of the resin during the molding of the cap main body 7 made of a heat-resistant resin is good, and the dimensions of the sealing surface 7d and the gas passage protrusion 7e are stable. Thus, it is possible to stably block the gas passage port 11.

[0049] The gas passage port 11 is arranged biased to the side of the sealing surface 7d and the gas passage protrusion 7e opposite to the first hinge part 8 (the front side). In addition, the area of the lower surface of the gas passage plug part 14b is larger than the sealing surface 7d in the entire circumferential direction in a planar view, and the gas passage plug part 14b abuts against and comes into close contact with the sealing surface 7d in a manner of covering the entire sealing surface 7d while elastically deforming.

[0050] Accordingly, the lower surface of the gas passage plug part 14b and the sealing surface 7d abut against each other in a surface contact manner, and thus the gas passage port 11 can be stably blocked regardless of the position thereof on the sealing surface 7d and the gas passage protrusion 7e, also including the case where the gas passage port 11 is arranged biased to the front side of the sealing surface 7d. In addition, blocking becomes less susceptible to the error of each mold cavity, and it is possible to stably block the gas passage port 11 no matter which mold is used for manufacturing.

[0051] The gas passage port 11 is arranged in a position that overlaps with the front side of the front end portion of the tubular wall portion 9d in a planar view (in FIG. 1, a position that overlaps with the front side of the front end portion of the tubular wall portion 9d in the vertical direction) in a state where the gas passage plug part 14b abuts against and is in close contact with the sealing surface 7d. In addition, in a state where the gas passage plug part 14b is in close contact with the sealing surface 7d, the inner peripheral side of the front end portion of the tubular wall portion 9d is located on the inner side of the sealing surface 7d in the front-rear direction in a planar view.

[0052] Accordingly, it comes into a state where the gas passage plug part 14b is strongly pressed downward against the gas passage port 11 by the front side of the front end portion of the tubular wall portion 9d, and it is possible to more reliably block the gas passage port 11.

[0053] In addition, the sealing surface 7d and the gas passage protrusion 7e have a length that is three times or more than three times the front-rear width of the gas passage port 11 in the front-rear direction. For example, in the prototype stage, it is possible to manufacture prototypes that respectively adopt positions where the gas passage port 11 is biased to the front side, located in the center, and biased to the rear side relative to the sealing surface 7d and the gas passage protrusion 7e without the repetition of the position of the gas passage port 11.

[0054] Accordingly, it is possible to manufacture prototypes in which only the position of the gas passage port 11 is changed and the state where the gas passage plug part 14b is in close contact with the entire sealing surface 7d is not changed, and confirm the blocking state of the gas passage port 11. In addition, it is easy to perform adjustment when a failure occurs in the blocking state of the gas passage port 11, and it is possible to suppress the development cost.

[0055] In the first hinge part 8, a first urging member (not shown) that urging the lid body 9 toward one side of a pivoting direction (hereinafter referred to as "opening direction") is arranged.

[0056] The first urging member consists of a spring member such as a torsion spring, and is attached to the inner side of the first hinge part 8.

[0057] Note that the first urging member is not limited to the one consisting of a spring member described above, but may alternatively be configured to urge the lid body 9 in the opening direction by retaining a ring-shaped elastic member including rubber, elastomer, or the like between the cap main body 7 and the lid body 9.

[0058] The cap unit 1A of the embodiment includes a lid locking mechanism 15 that fixes, to the cap main body 7, the lid body 9 which has been pivoted toward the other side of the pivoting direction (hereinafter referred to as "blocking direction") against the urging of the first urging member.

[0059] The lid locking mechanism 15 has a locking member 17 and a ring stopper 18 pivotably attached to the cap main body 7 via a second hinge part 16.

[0060] The locking member 17 is pivotably supported by the second hinge part 16 arranged on the front side of the cap main body 7 (the peripheral wall portion 7a). The locking member 17 has a first arm portion 17a extending upward from the second hinge part 16 and a second arm portion 17b extending downward from the second hinge part 16.

[0061] A hook part 19 is arranged at the front end of the first arm portion 17a (the upper end of the locking member 17) in a manner of protruding toward the rear.

[0062] A second urging member 20 consisting of a spring member such as a coil spring or the like is disposed between the second arm portion 17b and the peripheral wall portion 7a. Note that for the second urging member 20, an elastic member such as rubber, elastomer, or the like may alternatively be used instead of the spring member described above.

[0063] The ring stopper 18 consists of a ring-like member which is partially open, and two ends thereof are pivotably supported on the outer side of the second hinge part 16. Accordingly, the ring stopper 18 can pivot in the vertical direction.

[0064] On the other hand, the lid locking mechanism 15 has a locking receiving part 21 with which the hook part 19 of the locking member 17 is engaged, and a stopper receiving part 22 on which the ring stopper 18 is retained.

[0065] The locking receiving part 21 consists of a claw part protruding forward from the lower end portion on the front side of the lid body 9 (the peripheral wall 9a). The stopper receiving part 22 is shaped corresponding to the inner side of the ring stopper 18, and consists of a wall portion protruding forward from a position surrounding the periphery of the locking receiving part (claw part) 21.

[0066] In the lid locking mechanism 15, the hook part 19 of the locking member 17 is engaged with the locking receiving part 21 when the lid body 9 blocks the upper portion of the cap main body 7, and thereby the state where the lid body 9 blocks the upper portion of the cap main body 7 (the blocking position) is maintained.

[0067] By pressing the second arm portion 17b side of the locking member 17 against the urging of the second urging member 20 from this state, the engaged state of the hook part 19 with the locking receiving part 21 is released. Accordingly, the lid body 9 urged by the first urging member can be pivoted in the opening direction, thereby reaching the opening position.

[0068] On the other hand, in the lid locking mechanism 15, the ring stopper 18 is retained on the stopper receiving part 22 when the lid body 9 blocks the upper portion of the cap main body 7, and thereby the pivoting of the lid body 9 toward the opening direction is prevented. Accordingly, by the lid locking mechanism 15, the lid body 9 can be prevented from being opened due to an unnecessary (unintended) operation on the locking member 17.

[0069] In the container with a cap 100A that includes the cap unit 1A of the embodiment having the above-described configuration, by the above-described lid packing 14 in which the liquid passage plug part 14a that blocks the liquid passage port 10 and the gas passage plug part 14b that blocks the gas passage port 11 are arranged, it is possible to prevent the beverage in the container main body 2A from leaking to the outside from the liquid passage port 10 and the gas passage port 11.

[0070] Next, as a second embodiment of the present invention, for example, a container with a cap 100B that includes a cap unit 1B shown in FIG. 3 and FIG. 4 will be described.

[0071] Note that FIG. 3 is a cross-sectional view showing a state where a lid body 9 is blocked in the container with a cap 100B that includes the cap unit 1B. FIG. 4 is a perspective view showing a state where a liquid passage port 10 and a gas passage port 11 of the cap unit 1B are open. In addition, in the following description, parts equivalent to those of the cap unit 1A described above will not be described and will be given the same reference signs in the drawings.

[0072] As shown in FIG. 3 and FIG. 4, the container with a cap 100B of the embodiment includes the cap unit 1B of the embodiment and a container main body 2B to which the cap unit 1B is detachably attached.

[0073] The cap unit 1B of the embodiment has basically the same configuration as the cap unit 1A described above except that the gas passage port 11 of a cap main body 7 is arranged biased to the side of a first hinge part 8 (the rear side) of a sealing surface 7d and a gas passage protrusion 7e.

[0074] On the other hand, the container main body 2B has a larger capacity (size) than the container main body 2A described above, and the diameter of an upper opening 2d of the container main body 2B is greater than the diameter of the upper opening 2d of the container main body 2A described above.

[0075] In the cap unit 1B of the embodiment, the overall dimensions are larger than those of the cap unit 1A in accordance with the difference in the size between the container main body 2B and the container main body 2A. However, although the position of the gas passage port 11 on the cap main body 7 is different, the dimensions of the sealing surface 7d and the gas passage protrusion 7e are the same in the cap units 1A and 1B, and the same lid packing 14 is used. Thus, in the cap unit 1B, as in the cap unit 1A, a gas passage plug part 14b abuts against and comes into close contact with the sealing surface 7d in a manner of covering the entire sealing surface 7d while elastically deforming.

[0076] In addition, in the cap unit 1B of the embodiment, the lower surface of the gas passage plug part 14b and the sealing surface 7d abut against each other in a surface contact manner, and thus the gas passage port 11 can be stably blocked regardless of the position thereof on the sealing surface 7d and the gas passage protrusion 7e, also including the case where the gas passage port 11 is arranged biased to the rear side of the sealing surface 7d.

[0077] The gas passage port 11 is arranged in a position that overlaps with the rear side of the front end portion of a tubular wall portion 9d in a planar view (in FIG. 3, a position that overlaps with the rear side of the front end portion of the tubular wall portion 9d in a vertical direction) in a state where the gas passage plug part 14b is in close contact with the sealing surface 7d. In addition, in a state where the gas passage plug part 14b is in close contact with the sealing surface 7d, the inner peripheral side of the front end portion of the tubular wall portion 9d is located on the inner side of the sealing surface 7d in a front-rear direction in a planar view.

[0078] Accordingly, it comes into a state where the gas passage plug part 14b is strongly pressed downward against the gas passage port 11 by the rear side of the front end portion of the tubular wall portion 9d, and it is possible to more reliably block the gas passage port 11.

[0079] In the container with a cap 100B that includes the cap unit 1B of the embodiment having the above-described configuration, by the above-described lid packing 14, in which a liquid passage plug part 14a that blocks the liquid passage port 10 and the gas passage plug part 14b that blocks the gas passage port 11 are arranged, it is possible to prevent the beverage in the container main body 2B from leaking to the outside from the liquid passage port 10 and the gas passage port 11.

[0080] In addition, the cap unit 1A of the first embodiment described above and the cap unit 1B of the second embodiment described above use the same lid packing 14, although the position of the gas passage port 11 on the cap main body 7 is different in accordance with the difference in the size between the container main bodies 2A and 2B, as shown in FIG. 5.

[0081] In this case, in the cap unit 1A of the first embodiment described above, in a state where the gas passage plug part 14b abuts against and is in close contact with the sealing surface 7d, it comes into a state where, with respect to the gas passage port 11 arranged biased to the side of the sealing surface 7d opposite to the first hinge part 8 (the front side), the gas passage plug part 14b is strongly pressed downward against the gas passage port 11 by the front side of the front end portion of the tubular wall portion 9d.

[0082] On the other hand, in the cap unit 1B of the second embodiment described above, in a state where the gas passage plug part 14b abuts against and is in close contact with the sealing surface 7d, it comes into a state where, with respect to the gas passage port 11 arranged biased to the first hinge part 8 side (the rear side) of the sealing surface 7d, the gas passage plug part 14b is strongly pressed downward against the gas passage port 11 by the rear side of the front end portion of the tubular wall portion 9d.

[0083] The dimensions of the sealing surface 7d and the gas passage protrusion 7e are the same in the cap unit 1A and the cap unit 1B. That is, as shown in FIG. 5, the dimensions and positions of the sealing surface 7d, the gas passage protrusion 7e, and the gas passage plug part 14b (the lid packing 14) are completely consistent in the cap unit 1A and the cap unit 1B. In either the cap unit 1A or the cap unit 1B, the gas passage plug part 14b abuts against and comes into close contact with the sealing surface 7d in a manner of covering the entire sealing surface 7d while elastically deforming.

[0084] Accordingly, the lower surface of the gas passage plug part 14b and the sealing surface 7d abut against each other in a surface contact manner, and thus it is possible to appropriately block the gas passage port 11 using the same lid packing 14 without changing the dimensions or relative position of the gas passage plug part 14b relative to the sealing surface 7d and the gas passage protrusion 7e, even when the position of the gas passage port 11 on the cap main body 7 is different. Therefore, it is not necessary to prepare two types of lid packing 14 with different sizes, and it is possible to reduce the manufacturing cost.

[0085] In addition, in the cap unit 1A of the first embodiment described above and the cap unit 1B of the second embodiment described above, when the lid body 9 blocks the upper portion of the cap main body 7, the liquid passage plug part 14a blocks the liquid passage port 10 in a state of being in close contact with the surrounding region of the upper portion of the liquid passage port 10 while elastically deforming.

[0086] Here, in the cap unit 1A and the cap unit 1B, the dimensions or relative positions of the hole portion 9c, the liquid passage port 10, the liquid passage plug part 14a and the fitting protrusion 14c (the lid packing 14) are the same and completely consistent, as shown in FIG. 5. That is, similarly to the blocking of the gas passage port 11, it is possible to appropriately block the liquid passage port 10 without changing the dimensions or relative positions of the hole portion 9c, the liquid passage port 10, the liquid passage plug part 14a and the fitting protrusion 14c (the lid packing 14).

[0087] Note that these advantages are the same even in the case of the above-mentioned configuration in which the lid packing 14 is integrally attached to the lid body 9. That is, the same lid packing 14 can be used in the cap unit 1A and the cap unit 1B, and therefore, for example, in the case of insert molding, the lid packing 14 can be shared and used for molding respectively. In addition, in the cap unit 1A and the cap unit 1B, the gas passage port 11 and the liquid passage port 10 can be appropriately blocked equally.

[0088] As described above, the containers with a cap 100A and 100B of the embodiments make it possible to further improve the usability by including the cap units 1A and 1B that make it possible to stabilize the dimensions or moldability of the sealing part and appropriately block the liquid passage port 10 and the gas passage port 11 by the lid packing 14 while striving for the sharing of the lid packing 14.

[0089] Note that the present invention is not necessarily limited to the above-described embodiments, and various changes can be made without departing from the gist of the present invention.

[0090] For example, the above-described embodiments have illustrated the case where the present invention is applied to the above-described container for beverages having a hot/cold keeping function provided by the container main bodies 2A and 2B having a vacuum heat insulation structure, but the present invention can be widely applied to containers with a cap that include a container main body and a cap unit detachably attached to the container main body.
