FIG. 9 is a cross-sectional perspective view showing a state in which the lid body 8 is in an open position in a cross section of the cap unit 1 taken along a line CC shown in FIG. 4.

[0013] 1 to 4, a capped container 100 of this embodiment includes a cap unit 1 of this embodiment and a container body 2 to which the cap unit 1 is detachably attached. The capped container 100 is a tumbler (beverage container) that can keep a beverage (contents) contained in the container body 2 hot or cold by the container body 2 having a vacuum insulation structure.

[0014] Specifically, the container body 2 has a bottomed cylindrical outer container 3 and inner container 4 made of, for example, stainless steel, and is configured as a double-structure container in which the mouths of the outer container 3 and inner container 4 are joined together while the inner container 4 is housed inside the outer container 3. A vacuum insulation layer 5 is provided between the outer container 3 and the inner container 4. The vacuum insulation layer 5 can be formed, for example, by blocking a degassing hole provided in the center of the bottom surface of the outer container 3 in a chamber that has been reduced to a high vacuum (evacuated).

[0015] The container body 2 has a substantially circular bottom portion 2a, a substantially cylindrical body portion 2b that stands up from the outer periphery of the bottom portion 2a, and the upper end portion of the body portion 2b opens in a circular shape as an upper opening 2c of the container body 2.

[0016] Although the capped container 100 of this embodiment has a generally cylindrical external shape as a whole, the external shape of the capped container 100 is not particularly limited and can be modified as appropriate according to the size, design, etc. In addition, the outer circumferential surface of the container body 2 may be painted, printed, or the like.

[0017] The configuration of the cap unit 1 of this embodiment will be described with reference to FIGS. In the following explanation, the side of the cap unit 1 on which the liquid passage port 6 described later is provided will be referred to as the "front side" of the cap unit 1, and the side opposite the side on which the liquid passage port 6 is provided will be referred to as the "rear side" of the cap unit 1.

[0018] 3 to 6, the cap unit 1 of this embodiment constitutes a plug that closes the upper opening 2c of the container body 2. Specifically, the cap unit 1 includes a cap body 7 that closes the upper opening 2c of the container body 2 and has a liquid passage port 6 provided at the front upper part, a lid body 8 that opens and closes the liquid passage port 6 while being attached to the cap body 7 so as to be slidable in the front-rear direction, and a lid opening / closing mechanism 9 that holds the lid body 8, which slides between a closed position where the lid body 8 closes the liquid passage port 6 and an open position where the lid body 8 opens the liquid passage port 6, in the closed position and the open position.

[0019] The cap body 7 is made of a heat-resistant resin such as polypropylene (PP) or polymethylpentene (PMP). The cap body 7 has a substantially cylindrical peripheral wall portion 7a, a substantially disk-shaped upper wall portion 7b covering the upper portion of the peripheral wall portion 7a, an upper edge portion 7c protruding upward from the periphery of the upper wall portion 7b, an upper flange portion 7d protruding outward from the periphery of the upper edge portion 7c, and a lower flange portion 7e protruding outward from the periphery of the lower end side of the peripheral wall portion 7a.

[0020] The cap body 7 is configured to close the upper opening 2c of the container body 2 by abutting the lower surface of the upper flange portion 7d against the upper end of the container body 2 with the peripheral wall portion 7a fitted into the inside of the container body 2 from the upper opening 2c of the container body 2.

[0021] A waterproof gasket 10 is detachably attached to the peripheral wall portion 7a of the cap body 7. The waterproof gasket 10 is a ring-shaped sealing member for sealing the gap between the cap body 7 and the container body 2. The waterproof gasket 10 is made of an elastic material such as heat-resistant rubber, elastomer, etc., such as silicone rubber.

[0022] Correspondingly, a fitting recess 7f into which the waterproof gasket 10 is fitted is provided on the outer periphery of the peripheral wall portion 7a. The fitting recess 7f is provided in a ring shape extending between the upper flange portion 7d and the lower flange portion 7e.

[0023] Meanwhile, the inner periphery of the watertight gasket 10 is provided with a gripping piece 10a that protrudes in the direction of reducing the diameter. Correspondingly, the cap body 7 is provided with a cutout portion 7g that cuts out a part of the rear end side of the lower flange portion 7e. The watertight gasket 10 is fitted into the fitting recess 7f so that the gripping piece 10a is located inside the cutout portion 7g.

[0024] The water stop gasket 10 can be removed from the fitting recess 7f (cap body 7) by elastically deforming (pulling and stretching) the water stop gasket 10 itself while pinching the gripping piece 10a. This allows the water stop gasket 10 and the cap body 7 to be washed separately, and the space between the water stop gasket 10 and the fitting recess 7f (cap body 7) can be kept hygienic.

[0025] In addition, an elastic flange portion 10b is provided on the outer peripheral surface of the watertight gasket 10, which protrudes all around in the radially expanding direction. When the peripheral wall portion 7a of the watertight gasket 10 is fitted inside the container body 2, the elastic flange portion 10b elastically deforms and comes into close contact with the inner peripheral surface of the inner container 4 (container body 2) all around. This makes it possible to liquid-tightly seal (watertightly seal) the gap between the cap body 7 and the container body 2.

[0026] The lid 8 is made of a heat-resistant resin such as polypropylene (PP) or polymethylpentene (PMP). The lid 8 has a generally flat plate shape extending in the front-rear direction. The lid 8 is symmetrical in the front-rear direction and the left-right (width) direction.

[0027] Correspondingly, the cap body 7 is provided with a guide recess 11 that is formed by cutting out the upper wall portion 7b including the liquid passage port 6 in the front-rear direction with a width corresponding to the lid body 8. The guide recess 11 has a symmetrical shape in the front-rear direction.

[0028] The liquid passage port 6 is located at the front side of the guide recess 11 and is provided penetrating the bottom surface of the guide recess 11 in the thickness direction. The liquid passage port 6 opens from a position along the inner peripheral surface of the front side of the upper edge portion 7c toward the rear with a width corresponding to the bottom surface of the guide recess 11, and has a shape that opens narrower than the bottom surface of the guide recess 11 in the middle. The length A of the narrow opening portion is longer than the length B of the width portion corresponding to the bottom surface of the guide recess 11 (A>B). The narrow opening portion abuts against the bottom surface of the lid body 8, so that the sliding operation of the lid body 8 becomes smooth and it is possible to prevent the lid body 8 from falling off inside the liquid passage port 6.

[0029] The lid body 8 is disposed inside the guide recess 11, and is attached so as to be freely slidable in the front-rear direction of the cap body 7 along the guide recess 11. In addition, the lid body 8 has a symmetrical shape in the front-rear direction, and is therefore attached to the guide recess 11 in a manner that allows the lid body 8 to be freely switched from front to rear.

[0030] Furthermore, the lid body 8 has a shape that is flush with the cap body 7 when it is disposed inside the guide recess 11. Specifically, the upper surface of the upper wall portion 7b is curved concavely from the center toward the outer periphery. In accordance with this, the bottom surface of the guide recess 11 is also curved concavely in the front-rear direction. On the other hand, the lid body 8 has a shape that is curved upward in the front-rear direction in accordance with the shapes of the upper surface of the upper wall portion 7b and the bottom surface of the guide recess 11.

[0031] The lid body 8 closes the liquid passage port 6 in the closed position, and opens the liquid passage port 6 while partially overlapping the liquid passage port 6 in the open position. This makes it possible in the cap unit 1 of this embodiment to easily remove the lid body 8 from inside the guide recess 11 via the front end portion of the lid body 8 that partially overlaps the liquid passage port 6 in the open position.

[0032] An operating protrusion 12 for opening and closing the lid body 8 is provided on the top of the lid body 8. The operating protrusion 12 is provided to extend in the width direction in the center of the lid body 8 and protrude upward. In the cap unit 1 of this embodiment, the operating protrusion 12 makes it easy to slide the lid body 8 in the front-rear direction.

[0033] The lid opening / closing mechanism 9 has a pair of plungers 13 protruding from both sides of the lid body 8 in the width direction, and a pair of guide grooves 14 located on both sides of the lid body 8 of the cap body 7 in the width direction, and guides the pair of plungers 13 slidably in the front-to-rear direction of the cap body 7 while they are removably engaged with each other.

[0034] The pair of plungers 13 has a structure in which a ball (or pin) provided at the tip thereof is biased by a spring provided inside the plunger, and the ball (or pin) can be pushed inward against the bias of the spring. The pair of plungers 13 are located in the center of the lid body 8, and are attached with the ball (or pin) protruding from both side surfaces of the lid body 8 in the width direction.

[0035] The pair of guide grooves 14 are located in the center of the guide recess 11 and are formed by cutting out in the front-rear direction along both side surfaces of the guide recess 11 in the width direction.

[0036] In the lid opening / closing mechanism 9, when the lid body 8 is fitted inside the guide recess 11 from the top of the cap body 7, the pair of plungers 13 are engaged with the pair of guide grooves 14. In this state, the lid body 8 arranged inside the guide recess 11 can be held slidably in the front-rear direction.

[0037] Furthermore, when the pair of plungers 13 are engaged with the pair of guide grooves 14, the engagement width between the pair of plungers 13 and the pair of guide grooves 14 is wider than the width of the gap between the cover body 8 and the side surface of the guide recess 11, thereby enabling secure engagement.

[0038] On the other hand, in the lid opening / closing mechanism 9, by disengaging the pair of plungers 13 from the pair of guide grooves 14, it is possible to remove the lid body 8 from inside the guide recess 11 regardless of the position of the lid body 8 inside the guide recess 11.

[0039] In addition, the lid opening / closing mechanism 9 has a pair of front locking portions 15a located at the front end sides of the pair of guide grooves 14 and locking the pair of plungers 13, and a pair of rear locking portions 15b located at the rear end sides of the pair of guide grooves 14 and locking the pair of plungers 13.

[0040] The front and rear locking portions 15a, 15b are formed by protrusions protruding from the inside of the guide groove 14, dividing a portion of the front and rear ends of the guide groove 14, thereby forming recesses in which the plunger 13 is locked.

[0041] In the lid opening / closing mechanism 9, as shown in FIG. 7, after a pair of plungers 13 guided by a pair of guide grooves 14 overcome the protrusion, the pair of plungers 13 are engaged with a pair of front engagement portions 15a, thereby making it possible to hold the lid body 8 in the closed position shown in FIG. 8.

[0042] On the other hand, in the lid opening / closing mechanism 9, as shown in FIG. 7, after a pair of plungers 13 guided by a pair of guide grooves 14 overcome the protrusion, the pair of plungers 13 are engaged with a pair of rear engagement portions 15b, thereby making it possible to hold the lid body 8 in the open position shown in FIG. 9.

[0043] In the capped container 100 of this embodiment having the above-mentioned configuration, when the container body 2 is tilted forward, the front side of the above-mentioned upper edge portion 7c serves as a drinking spout, and it is possible to drink the beverage (contents) flowing out of the container body 2 through the liquid passage 6.

[0044] As described above, the cap unit 1 of the present embodiment includes the above-mentioned lid opening and closing mechanism 9, and thus the lid body 8 can be easily attached to and detached from the cap body 7 while having a simple structure.

[0045] Specifically, in the cap unit 1, the lid opening / closing mechanism 9 described above has the pair of plungers 13 engaged with the pair of guide grooves 14, thereby making it possible to hold the lid body 8 arranged inside the guide recess 11 slidably in the front-rear direction. On the other hand, by releasing the engagement between the pair of plungers 13 and the pair of guide grooves 14, the lid body 8 can be easily removed from any position inside the guide recess 11.

[0046] Furthermore, in the cap unit 1 of the present embodiment, the cap body 7 and the lid body 8 can be washed separately, and the space between the cap body 7 and the lid body 8 can be kept hygienic.

[0047] Furthermore, in the capped container 100 of this embodiment, by being equipped with such a cap unit 1, the lid body 8 can be easily opened and closed with one hand while holding the container body 2, thereby further improving usability.

[0048] The present invention is not necessarily limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention. For example, in the above-mentioned lid opening / closing mechanism 9, a pair of plungers 13 located in the center of the above-mentioned lid body 8 are configured to protrude from both sides of the lid body 8 in the width direction, but this pair of plungers 13 may also be configured to be provided on both sides of the lid body 8 in the front-to-rear direction.

[0049] In such a configuration, a guide groove 14, a front locking portion 15a, and a rear locking portion 15b may be provided to match the front plunger 13, and a guide groove 14, a front locking portion 15a, and a rear locking portion 15b may be provided to match the rear plunger 13.

[0050] In the above embodiment, the upper surface of the upper wall portion 7b and the lid body 8 have a concave curved shape extending from the center toward the outer periphery, but it is also possible for the upper surface of the upper wall portion 7b and the lid body 8 to have a flat shape or a shape that is inclined toward the front or rear.

[0051] In the above embodiment, an example is shown of the application of the present invention to a tumbler (beverage container) that has a heat / cold insulation function provided by the container body 2 having the vacuum insulation structure described above, but the lid opening and closing mechanism 9 of the present invention can be widely applied to a capped container that includes a container body and a cap unit that can be freely attached and detached to the container body.
