FIG. 9 is a plan view of the lid body 8 of the cap unit 1 seen from below.

[0014] 1 and 2, the 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 attached. The capped container 100 of this embodiment is a tabletop pot (beverage container) that can keep a beverage (liquid) contained in the container body 2 hot or cold by the container body 2 having a vacuum insulation structure.

[0015] In addition, in the capped container 100 of this embodiment, the side on which the spout 10 described below is provided will be treated as the "front side," and the side on which the handle portion 11 located opposite the spout 10 is provided will be treated as the "rear side."

[0016] 1, 2, and 3, the container body 2 is configured as a double-structure container having a bottomed cylindrical outer container 3 and inner container 4 made of, for example, stainless steel, with the inner container 4 housed inside the outer container 3 and the periphery of their openings joined together. 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 vent hole provided in the bottom of the outer container 3 in a chamber that has been reduced to a high vacuum (evacuated).

[0017] The container body 2 has a substantially circular bottom 2a, a body 2b that stands up in a substantially cylindrical shape from the outer periphery of the bottom 2a, a substantially cylindrical mouth / neck 2c that is tapered in diameter at the upper side of the body 2b, and a shoulder 2d that gradually tapers in diameter from the body 2b toward the mouth / neck 2c. The upper end of the mouth / neck 2c opens in a circular shape as an upper opening 2e of the container body 2. The inner circumferential surface of the mouth / neck 2c is tapered in diameter more than the inner circumferential surface of the body 2b. A ring-shaped protrusion 6 is provided on the inner circumferential surface of the mouth / neck 2c so as to protrude around the entire circumference.

[0018] The container body 2 of this embodiment has an overall cylindrical shape with a bottom, and a tapered diameter from the lower side to the upper side of the barrel portion 2b, but the external shape of the container body 2 is not particularly limited and can be modified as appropriate to suit the size, design, etc. The outer peripheral surface of the container body 2 may be painted, printed, or the like.

[0019] As shown in Figures 3 to 9, the cap unit 1 of this embodiment comprises a cap body 7 that is attached to the neck portion 2c and shoulder portion 2d of the container body 2, and a lid body 8 that is fitted into the inside of the cap body 7 through a liquid passage 7a provided in the cap body 7.

[0020] As shown in Figures 1, 2 and 3, the cap body 7 is a shoulder member made of, for example, a heat-resistant resin, and is attached to the mouth neck portion 2c of the container body 2 via a mouth gasket 9A and a shoulder gasket 9B, while forming a circular liquid passage port 7a that communicates with the inside of the container body 2.

[0021] The mouth gasket 9A and shoulder gasket 9B are ring-shaped sealing members that seal the gap between the neck portion 2c and shoulder portion 2d of the container body 2 and the cap body 7, and are made of an elastic material such as heat-resistant rubber or elastomer, for example, silicone rubber.

[0022] The cap body 7 is fitted onto the mouth and neck portion 2c of the container body 2 so as to be flush with the outer surface of the body portion 2b of the container body 2, covering the mouth and neck portion 2c, shoulder portion 2d and upper opening 2e of the container body 2 via the mouth gasket 9A and shoulder gasket 9B.

[0023] The neck gasket 9A is placed over the upper end of the neck portion 2c to seal the gap between the neck portion 2c of the container body 2 and the cap body 7. The inner periphery of the neck gasket 9A extends to the vicinity of the lower end of the inner periphery of the cap body 7. This prevents the beverage in the container body 2 from entering the gap between the neck portion 2c of the container body 2 and the cap body 7 and from leaking out.

[0024] Meanwhile, shoulder packing 9B seals the gap between shoulder 2d of container body 2 and cap body 7 while being positioned at least between shoulder 2d of container body 2 and the surface (underside) of cap body 7 facing shoulder 2d. This prevents water and the like from entering the gap between shoulder 2d of container body 2 and cap body 7 from the outside during cleaning, etc.

[0025] The cap body 7 has a spout 10 for pouring the beverage in the container body 2 to the outside, and a handle 11 for the user to grip.

[0026] Spout 10 is located on the front side surface of cap body 7 and protrudes in the radial direction from one end of the upper part of liquid passage port 7a. Specifically, spout 10 is configured as a groove that protrudes forward while slanting diagonally upward from the front side surface of cap body 7.

[0027] Handle 11 is provided on the side opposite spout 10, i.e., the rear side of cap body 7, protruding rearward and extending downward. Note that handle 11 is not necessarily limited to this shape, and its shape can be modified as appropriate.

[0028] As shown in FIGS. 1 to 9, the lid 8 is a plug having a heat insulating structure, and is detachably attached to the cap body 7 so as to be able to open and close the opening 7b.

[0029] Specifically, as shown in Figures 2 and 3, the lid body 8 has an upper lid 12 and an inside plug 13 made of, for example, heat-resistant resin. The upper lid 12 covers the upper part of the cap body 7 and is formed in a flat, circular plate shape corresponding to the liquid passage hole 7a of the cap body 7. The inside plug 13 is fitted inside the cap body 7 and has a generally cylindrical shape with a bottom. It is integrally attached to the center of the underside of the upper lid 12 by welding or the like. A heat insulating material S made of, for example, urethane foam resin is disposed inside the inside of the inside plug 13 as a heat insulating layer. Instead of the heat insulating material S, air (voids) may be used as the heat insulating layer.

[0030] 3 to 9, the lid body 8 is provided with a step portion 14 along the entire periphery between the liquid passage port 7a and the inside plug 13 fitted inside the cap body 7. Meanwhile, the inside of the cap body 7 is provided with an abutment surface portion 7c that abuts against the step portion 14.

[0031] In the cap unit 1 of this embodiment, as shown in Figures 1 and 3, when the inner plug 13 is inserted into the inside of the cap body 7 through the liquid passage 7a, the step portion 14 abuts against the abutment surface portion 7c of the cap body 7, and the opening 7b can be covered by the lid body 8.

[0032] As shown in Figures 1 to 3 and 6 to 9, the lid 8 has a fitting protrusion 15 that protrudes rearward from the rear side surface of the inside plug 13. The fitting protrusion 15 is provided in the shape of a flat plate and protrudes so as to face the upper surface of the handle 11. Meanwhile, the upper surface of the handle 11 is provided with a fitting recess 16 into which the fitting protrusion 15 is fitted. When fitted into the fitting recess 16, the fitting protrusion 15 is substantially flush with the upper surface of the handle 11.

[0033] In the cap unit 1 of this embodiment, when fitting the lid body 8 inside the cap body 7, the fitting convex portion 15 is fitted into the fitting concave portion 16, making alignment easy. Furthermore, when a user grips the handle portion 11, the user can press the fitting convex portion 15 fitted into the fitting concave portion 16 with their fingers, thereby preventing the lid body 8 fitted inside the cap body 7 from coming off the cap body 7 through the liquid passage port 7a.

[0034] As shown in Figures 3 to 9, the lid body 8 has a liquid passage groove 17 that, together with the spout 10, forms a flow path R for allowing the beverage in the container body 2 to flow out, and an air passage groove 18 that introduces outside air into the inside of the container body 2.

[0035] Liquid passage groove 17 is located on the front side surface of inside plug 13, and is cut out in the vertical direction from the side surface opposite spout 10 to the bottom surface. Liquid passage groove 17 has a groove shape in which width W2 of the lower end facing the bottom surface is larger than width W1 of the upper end facing the side surface of inside plug 13, and depth D2 of the lower end facing the bottom surface is larger than depth D1 of the upper end facing the side surface of inside plug 13.

[0036] Width W1 is the width of overhang portion 19 (described later) extending in the circumferential direction. Width W2 is the width of liquid passage groove 17 extending in the circumferential direction at the bottom surface of inside plug 13. Depth D1 is the distance between bottom upper portion 17a of liquid passage groove 17 and the inner surface of spout 10. Depth D2 is the distance between bottom side portion 17b of liquid passage groove 17 and liquid passage opening 7a.

[0037] In the cap unit 1 of this embodiment, as shown in Figure 3, when the inner stopper 13 is fitted into the inside of the cap body 7 from the liquid passage port 7a, a flow path R is formed from the spout 10 to the liquid passage groove 17.

[0038] 4 and 5, a generally U-shaped eaves portion 19 is provided on the side of inside plug 13 facing spout 10, and protrudes slightly forward to surround the upper end of fluid passage groove 17. Eaves portion 19 also extends downward to the position where step portion 14 is formed.

[0039] In the cap unit 1 of this embodiment, when the step portion 14 is in contact with the contact surface 7c of the cap body 7 described above, both ends of the eaves portion 19 are in contact with the inner surface of the spout 10. As a result, when the beverage in the container body 2 is poured out through the spout 10, the contact surface 7c and the step portion 14 simply stop the water flow, preventing the beverage from flowing toward the opening 7b, and also preventing the beverage that has flowed from the liquid passage port 7a along the contact surface 7c to the spout 10 from disrupting the flow of the beverage being poured from the liquid passage groove 17.

[0040] As shown in Figures 3 and 6 to 9, the ventilation groove 18 is located on the opposite side to the liquid passage groove 17, i.e., on the rear side surface of the inside plug 13, and is provided so as to cut out the lower part of the fitting protrusion 15 in the vertical direction between it and the step portion 14.

[0041] In the cap unit 1 of this embodiment, when the beverage in the container body 2 is poured out through the spout 10, external air is introduced into the inside of the container body 2 through the ventilation groove 18. This prevents pulsation caused by air flowing in from the liquid passage groove 17 side, allowing the beverage in the container body 2 to be poured out smoothly through the spout 10, and when the lid body 8 is fitted inside the cap body 7, the ventilation groove 18 is covered by the fitting protrusion 15 and is not exposed to the outside, allowing the aesthetic appearance of the cap unit 1 to be improved.

[0042] In the capped container 100 having the cap unit 1 of this embodiment configured as described above, it is possible to make it easier to pour the beverage flowing out of the container body 2 through the flow path R from the spout 10.

[0043] Specifically, in this cap unit 1, the above-mentioned liquid passage groove 17 is provided so as to cut out from the side surface of inside plug 13 that faces spout 10 and liquid passage port 7a to the bottom surface. Furthermore, this liquid passage groove 17 has a groove shape in which the width W2 of the lower end facing the bottom surface is larger than the width W1 of the upper end facing the side surface of inside plug 13, and the depth D2 of the lower end facing the bottom surface is larger than the depth D1 of the upper end facing the side surface of inside plug 13, and the cross-sectional area of ​​liquid passage groove 17 gradually decreases toward spout 10.

[0044] This increases the speed at which the beverage flows through the liquid passage groove 17, reducing the frictional energy between the beverage and the liquid passage groove 17, which can cause turbulence in the discharge, and enabling the beverage in the container body 2 to be poured smoothly from the spout 10. It also prevents the beverage from pulsating and splashing around.

[0045] Furthermore, in the cap unit 1 of this embodiment, a visor portion 19 is provided that surrounds the periphery of the upper end side of the above-mentioned liquid passage groove 17, and this visor portion 19 can regulate the flow of beverage that flows out from the upper end side of the liquid passage groove 17 to the spout 10. Furthermore, visor portion 19 can prevent the beverage that flows out from the upper end side of the liquid passage groove 17 facing the above-mentioned spout 10 from flowing toward the top lid 12, or the beverage that flows from the liquid passage port 7a along the contact surface portion 7c to the spout 10 from disrupting the flow of beverage poured from the liquid passage groove 17.

[0046] Furthermore, in the cap unit 1 of this embodiment, the step portion 14 abuts against the abutment surface portion 7c, thereby simply stopping water flow and preventing the beverage from flowing toward the opening portion 7b.

[0047] In addition, in the cap unit 1 of this embodiment, when the lid body 8 is fitted inside the cap body 7, the fitting convex portion 15 is fitted into the fitting concave portion 16, making it easy to align the flow path R formed by the spout 10 and the liquid passage groove 17.

[0048] As described above, the cap unit 1 of this embodiment can prevent the beverage from splashing due to the pulsation of the beverage flowing out of the spout 10, and can keep the surrounding area and the cap unit 1 hygienic.

[0049] Furthermore, the cap unit 1 of this embodiment can be easily cleaned due to the simple structure of the cap body 7 and the lid body 8. Therefore, by providing the capped container 100 of this embodiment with such a cap unit 1, it is possible to further improve usability.

[0050] 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.

[0051] For example, the above embodiment illustrates a capped container 100 applied to the above-mentioned tabletop pot, but the present invention can be widely applied to capped containers equipped with a cap unit that is attached to a container body with an open top.

[0052] Furthermore, in the above embodiment, a capped container 100 having heat and cold insulation functions is exemplified by a container body 2 having the above-mentioned vacuum insulation structure, but the present invention can also be applied to a capped container having a container body that does not have a vacuum insulation structure.
