DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. As one embodiment of the present invention, a capped container 100 including a cap unit 1 shown in, for example, FIGS. 1 to 9 will be described.

[0013] FIG. 1 is a perspective view showing the appearance of the capped container 100. FIG. 2 is a cross-sectional view showing the configuration of the capped container 100. FIG. 3 is a cross-sectional view showing the capped container 100 in a closed state. FIG. 4 is a cross-sectional view showing the capped container 100 in an open state. FIG. 5 is an exploded perspective view of one side of the capped container 100 as viewed from above. FIG. 6 is an exploded perspective view of the other side of the capped container 100 as viewed from above. FIG. 7 is an exploded perspective view of the other side of the capped container 100 as viewed from below. FIG. 8 is a cross-sectional view of the horizontal section of the cap unit 1 as viewed from below. FIG. 9 is a top view showing the configuration of the cap unit 1.

[0014] As shown in Figures 1 and 2, the capped container 100 of this embodiment comprises a cap unit 1 of this embodiment, a container body 2 to which the cap unit 1 is removably attached, and a cup 3 that is removably attached to the container body 2 while covering the cap unit 1.

[0015] The capped container 100 is a beverage container capable of keeping a beverage (contents) contained in the container body 2 hot or cold by the container body 2 having a vacuum insulation structure.

[0016] Specifically, the container body 2 has a bottomed cylindrical outer container 4 and inner container 5 made of, for example, stainless steel, and is configured as a double-structure container in which the mouths of the outer container 4 and inner container 5 are joined together while the inner container 5 is housed inside the outer container 4. In addition, a vacuum insulation layer 6 is provided between the outer container 4 and the inner container 5. The vacuum insulation layer 6 can be formed, for example, by blocking a degassing hole provided in the center of the bottom surface of the outer container 4 in a chamber that has been reduced to a high vacuum (evacuated).

[0017] The container body 2 has a substantially circular bottom surface 2a, a body portion 2b that stands in a substantially cylindrical shape from the outer periphery of the bottom surface 2a, and a substantially cylindrical mouth-neck portion 2c that is tapered at the upper side of the body portion 2b. The upper end of the mouth-neck portion 2c opens in a circular shape as an upper opening portion 2d of the container body 2.

[0018] The inner circumference of the mouth-neck portion 2c is smaller in diameter than the inner circumference of the body portion 2b. A male thread portion 7 is provided on the outer circumference of the mouth-neck portion 2c. Meanwhile, a female thread portion 8 is provided on the inner circumference of the mouth-neck portion 2c. Furthermore, below the female thread portion 8, a protruding portion 9 is provided so as to protrude from the inner circumference of the container body 2 all around.

[0019] The cup 3 is made of a heat-resistant resin such as polypropylene, and has a substantially circular bottom wall portion 3a and a cylindrical peripheral wall portion 3b that rises upward (downward in Figures 1 and 2) from the periphery of the bottom wall portion 3a, and is formed as a bottomed cylinder overall.

[0020] The cup 3, with the bottom wall portion 3a facing upward, is detachably attached by screwing to the outside of the mouth and neck portion 2c of the container body 2. For this reason, a female screw portion 10 that screws into the male screw portion 7 is provided on the inner peripheral portion of the peripheral wall portion 3b.

[0021] 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 surfaces of the container body 2 and the cup 3 may be painted, printed, or the like.

[0022] 2 to 7, the cap unit 1 of this embodiment includes a lid 11 that closes the upper opening 2d of the container body 2. The lid 11 is made of a heat-resistant resin such as polypropylene, and includes an inner plug 12 that is fitted into the inside of the container body 2 through the upper opening 2d of the container body 2, and a top cover 13 that protrudes from the outer periphery of the upper end side of the inner plug 12 over the entire circumference.

[0023] The lid body 11 has a bottomed, generally cylindrical lower lid member 14a constituting the inner plug 12 and the lid 13, and a generally circular upper lid member 14b constituting the lid 13, with the lower lid member 14a being attached integrally to the lower surface of the upper lid member 14b by ultrasonic welding, high-frequency welding, etc. The inside of the lid body 11 is configured to have a thermal insulating material S arranged therein, but may be air as a thermal insulating layer.

[0024] The inner stopper 12 has an outer periphery provided with a male thread portion 15 that screws into the female thread portion 8 of the container body 2. As a result, the lid body 11 is detachably attached to the container body 2 by screwing the female thread portion 8 and the male thread portion 15 together. Therefore, the cap unit 1 of this embodiment has a structure in which the lid body 11 attached by screwing the female thread portion 8 and the male thread portion 15 together closes the upper opening 2d of the container body 2.

[0025] A watertight gasket 16 is detachably attached to the lower end of the inside plug 12. The watertight gasket 16 is a ring-shaped seal member made of an elastic material such as heat-resistant rubber, elastomer, etc., such as silicone rubber. Meanwhile, a flange portion 12a is provided on the lower end of the inside plug 12, protruding in the radially expanding direction around the entire circumference. The watertight gasket 16 is fitted around the entire circumference of this flange portion 12a.

[0026] Furthermore, the outer peripheral surface of the water stop packing 16 is provided with a plurality of elastic flange portions 16a (two in this embodiment) arranged in the vertical direction and protruding in the radial direction. When the lid 11 is attached to the container body 2, the water stop packing 16 is in a state of being in close contact with the overhanging portion 9 of the container body 2 over the entire circumference while the elastic flange portions 16a are elastically deformed. This makes it possible to seal the gap between the overhanging portion 9 (container body 2) and the inner plug 12. Note that the shape of the water stop packing 16 for being in close contact with the overhanging portion 9 is not necessarily limited to the shape of the elastic flange portions 16a described above, and the shape, number, etc. can be appropriately changed.

[0027] On the other hand, the water stop gasket 16 can be removed from the flange portion 12a by elastically deforming (pulling and stretching) the water stop gasket 16. This allows the water stop gasket 16 and the inner plug 12 to be washed separately, and the space between the water stop gasket 16 and the inner plug 12 can be kept hygienic.

[0028] The watertight gasket 16 is not limited to being detachably attached to the inner plug 12 as described above, but may be attached integrally to the inner plug 12 by being integrally molded with the inner plug 12 or by being bonded thereto.

[0029] As shown in Figures 3 to 9, the cover 11 has a first liquid passage groove 17 and a second liquid passage groove 18 at opposing positions on the outer periphery of the inside plug 12. The first liquid passage groove 17 and the second liquid passage groove 18 have a pair of side surfaces 17b, 18b that rise parallel to each other from both sides of the bottom surfaces 17a, 18a, respectively, and are provided so as to cut out the male screw portion 15 in the vertical direction on the outer periphery of the inside plug 12. The first liquid passage groove 17 and the second liquid passage groove 18 are also provided so as to cut out a part of the lower surface side of the lid 13.

[0030] The first liquid passage groove 17 and the second liquid passage groove 18 are different in size from each other. That is, the first liquid passage groove 17 and the second liquid passage groove 18 have different widths W1 and W2 from each other, and the width W1 of the first liquid passage groove 17 is smaller than the width W2 of the second liquid passage groove 18.

[0031] Moreover, the width W1 of the first liquid passage groove 17 is preferably 1 / 2 or less of the width W2 of the second liquid passage groove 18. Moreover, the cross-sectional area of ​​the first liquid passage groove 17 is preferably 10 to 70% of the cross-sectional area of ​​the second liquid passage groove 18, and more preferably 15 to 40%.

[0032] The canopy 13 is provided with a first recess 19a indicating the position of the first liquid passage groove 17 and a second recess 19b indicating the position of the second liquid passage groove 18, in accordance with the first liquid passage groove 17 and the second liquid passage groove 18 having different widths W1, W2.

[0033] The first recess 19a has a shape in which a position on the upper surface and side surface of the lid 13 corresponding to the first liquid passage groove 17 is recessed by one step wider than the first liquid passage groove 17. Similarly, the second recess 19b has a shape in which a position on the upper surface and side surface of the lid 13 corresponding to the second liquid passage groove 18 is recessed by one step wider than the second liquid passage groove 18.

[0034] The first recess 19a and the second recess 19b have different widths corresponding to the widths of the first liquid passage groove 17 and the second liquid passage groove 18. This is very convenient because it makes it possible to distinguish the difference in position and width between the first liquid passage groove 17 and the second liquid passage groove 18 even when the lid body 11 is viewed from above.

[0035] The configuration for indicating the positions of the first fluid passage groove 17 and the second fluid passage groove 18 on the canopy 13 is not limited to the configuration having the first recess 19a and the second recess 19b, but can be modified as appropriate.

[0036] Additionally, a plurality of anti-slip protrusions 20 are provided on the outer periphery of the canopy 13. The anti-slip protrusions 20 are arranged at equal intervals in the circumferential direction between the first recess 19a and the second recess 19b. Note that the anti-slip feature is not limited to the provision of a plurality of anti-slip protrusions 20 as described above, and can be modified as appropriate.

[0037] In the capped container 100 including the cap unit 1 of this embodiment having the above-mentioned configuration, after removing the above-mentioned cup 3, the lid 11 is turned to partially release the screw engagement between the female screw portion 8 and the male screw portion 15. By tilting the container body 2 from this state, it is possible to pour the beverage (liquid) in the container body 2 into the cup 3 through the first liquid passage groove 17 or the second liquid passage groove 18 without removing the lid 11 from the container body 2.

[0038] In the cap unit 1 of this embodiment, since the above-mentioned first liquid passage groove 17 and second liquid passage groove 18 have different sizes, it is possible to make the amount of liquid flowing out through the first liquid passage groove 17 different from the amount of liquid flowing out through the second liquid passage groove 18.

[0039] Specifically, when liquid in the container body 2 is made to flow out from the narrow first liquid passage groove 17 side, it is possible to reduce the amount of liquid flowing out from this first liquid passage groove 17. In this case, it is suitable for pouring hot water into a dripper, for example. (Note that in this case, the width W1 of the first liquid passage groove 17 is preferably 7 mm or less.) Also, it is possible to increase the amount of air flowing in by taking in outside air into the container body 2 from the wider second liquid passage groove 18 side. This makes it possible to improve the drainage of the liquid flowing out from the first liquid passage groove 17 and prevent liquid leakage from the second liquid passage groove 18 side.

[0040] On the other hand, when the liquid in the container body 2 is made to flow out from the wider second liquid passage groove 18 side, it is possible to increase the amount of liquid flowing out from this second liquid passage groove 18. In this case, it is suitable for pouring a beverage into a cup 3, for example. Also, by taking in outside air into the container body 2 from the narrower first liquid passage groove 17 side, it is possible to limit the amount of air that flows in. This makes it possible to stabilize the flow of the liquid flowing out from the second liquid passage groove 18, and to prevent pulsation from occurring in the liquid flowing out from this second liquid passage groove 18.

[0041] In addition, in the cap unit 1 of this embodiment, by having a pair of side surfaces 17b, 18b that rise parallel to each other from both sides of the bottom surfaces 17a, 18a of the above-mentioned first liquid passage groove 17 and second liquid passage groove 18, it is possible to make the widths W1, W2 of these first liquid passage groove 17 and second liquid passage groove 18 constant, stabilize the direction and flow of the liquid flowing out from the first liquid passage groove 17 and second liquid passage groove 18, and suppress the splashing of the liquid.

[0042] Furthermore, the first liquid passage groove 17 and the second liquid passage groove 18 are not limited to a configuration in which a pair of side surfaces 17b, 18b rise up parallel to bottom surfaces 17a, 18a curved in an arc shape in the circumferential direction of the inside plug 12 as shown in Fig. 8 described above, but may have a shape in which the pair of side surfaces 17b, 18b spread out in a fan shape in a direction away from each other. In this case, the pair of side surfaces 17b, 18b are preferably formed to rise up at an angle range of 90° to 100° with respect to the tangent direction of the bottom surfaces 17a, 18a.

[0043] In particular, when the pair of side surfaces 17b, 18b are formed to rise at 90° (vertically), it is possible to stabilize the flow of liquid and suppress the scattering of liquid. Furthermore, such an effect is more remarkable in the first liquid passage groove 17, which is narrower than the second liquid passage groove 18, which is wider.

[0044] In the cap unit 1 of this embodiment, the above-mentioned first liquid passage groove 17 and second liquid passage groove 18 are provided by cutting out a part of the lower surface side of the canopy 13. In this case, it is possible to make the positions of the first liquid passage groove 17 and second liquid passage groove 18 easier to visually confirm.

[0045] Furthermore, when the container body 2 is tilted significantly with the first liquid passage groove 17 or the second liquid passage groove 18 serving as the liquid passage port facing downward, liquid may leak from the upper end side of the second liquid passage groove 18 or the first liquid passage groove 17 serving as the air vent. In this case, the liquid leaking from the upper end side of the second liquid passage groove 18 or the first liquid passage groove 17 serving as the air vent can be blocked by the upper end of the first liquid passage groove 17 and the second liquid passage groove 18, which are cut out from a part of the lower surface side of the lid 13, from flowing around the lid body 11 into the first liquid passage groove 17 or the second liquid passage groove 18 serving as the liquid passage port.

[0046] As described above, the cap unit 1 of this embodiment makes it possible to easily adjust the amount of beverage flowing out through the first liquid passage groove 17 and the second liquid passage groove 18. Therefore, by providing the capped container 100 of this embodiment with such a cap unit 1, it is possible to further improve usability.

[0047] 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.

[0048] For example, in the cap unit 1 of this embodiment, the widths W1, W2 of the first liquid passage groove 17 and the second liquid passage groove 18 described above are different, but by making the depths or cross-sectional areas of the flow paths of the first liquid passage groove 17 and the second liquid passage groove 18 different, it is also possible to make the amount of liquid flowing out through the first liquid passage groove 17 and the amount of liquid flowing out through the second liquid passage groove 18 different.

[0049] In addition, the cap unit to which the present invention is applied is not necessarily limited to the configuration of the cap unit 1 described above. For example, the present invention can be applied to a cap unit having a structure in which a cap body is attached to the mouth neck part of a container body with an open top and has a liquid passage hole communicating with the inside of the container body, and a lid body provided with an inner plug that closes the liquid passage hole when fitted inside the cap body, and the lid body is attached by screwing a female screw part provided on the inner periphery of the container body or the cap body and a male screw part provided on the outer periphery of the inner plug, and closes the liquid passage hole. That is, this cap unit can also be configured to have a first liquid passage groove and a second liquid passage groove of different sizes provided at opposing positions on the outer periphery of the inner plug.

[0050] In the above embodiment, the present invention is applied to a capped container 100 having a heat insulation / cold insulation function provided by the container body 2 having the above-mentioned vacuum insulation structure, but the present invention is not necessarily limited to a container having a container body 2 having such a vacuum insulation structure. In other words, the present invention can be widely applied to a capped container in which a cap unit is detachably attached to the mouth and neck portion of the container body.
