FIG. 2 is a perspective view showing a capped container 100 equipped with a cap unit 1 in an open state. FIG. 3 is a cross-sectional view showing a capped container 100 equipped with a cap unit 1 in a closed state. FIG. 4 is a cross-sectional view showing a capped container 100 equipped with a cap unit 1 in an open state. FIG. 5 is a perspective view showing the configuration of the cap unit 1. FIG. 6 is an exploded perspective view showing the configuration of the cap unit 1. FIG. 7 is a perspective view showing the inside of the cap unit 1.

[0015] As shown in Figures 1 to 4, the capped container 100 of this embodiment comprises a cap unit 1 of this embodiment and a container body 2 to which the cap unit 1 can be attached and detached, and the container body 2 is a container with a tea strainer that is equipped with a tea strainer for placing tea leaves or the like therein to extract tea.

[0016] The container body 2 has a bottomed cylindrical outer container 3 and an 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 the 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).

[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 peripheral surface of the mouth / neck portion 2c is smaller in diameter than the inner peripheral surface of the body portion 2b. A first female screw portion 6 is provided on the inner peripheral surface of the mouth / neck portion 2c. The first female screw portion 6 is composed of a screw thread that protrudes downward in a spiral shape from the upper end side of the mouth / neck portion 2c. Furthermore, below the first female screw portion 6, a ring-shaped protruding portion 7 is provided protruding from the inner peripheral surface of the container body 2 all around.

[0019] 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 appropriately changed according to the size, design, etc. In addition, the outer peripheral surface of the container body 2 may be painted, printed, or the like.

[0020] As shown in Figures 3 to 7, the cap unit 1 of this embodiment constitutes a stopper body that closes the upper opening 2d of the container body 2, and comprises a cap body 8, a lid body 9 that is removably attached to the cap body 8, and a tea strainer member 10 that is removably attached to the cap body 8.

[0021] The cap body 8 is made of a heat-resistant resin such as polypropylene (PP). The cap body 8 has a liquid passage hole 11 that communicates with the inside of the container body 2, a bottom wall portion 12 in which the liquid passage hole 11 is formed, a peripheral wall portion 13 formed by rising upward from the periphery of the bottom wall portion 12, an expansion wall portion 14 formed by rising upward from the peripheral wall portion 13 while gradually expanding in diameter, a pair of pouring spout portions 15 that are parts of the expansion wall portions 14 protruding in the direction of expansion in diameter, and a pair of groove portions 16 formed continuous with the pouring spout portions 15 and cutting out parts of the inner circumferential surface of the peripheral wall portion 13 toward the bottom wall portion 12.

[0022] The liquid passage hole 11 opens in a circular shape at the center of the bottom surface of the bottom wall portion 12. The bottom wall portion 12 is inclined (reduced in diameter) downward from the peripheral wall portion 13 toward the liquid passage hole 11. The peripheral wall portion 13 has the same diameter (cylindrical shape) between the bottom wall portion 12 and the expanding wall portion 14. The expanding wall portion 14 is inclined (expanded in diameter) upward from the peripheral wall portion 13 toward the upper end portion of the cap body 8.

[0023] The pair of pouring spouts 15 are disposed symmetrically at positions facing each other on the expanded wall portion 14. Each pouring spout 15 is inclined (expanded in diameter) more than the expanded wall portion 14 from the peripheral wall portion 13 toward the upper end portion of the cap body 8 by causing a part of the expanded wall portion 14 to protrude in the diameter expanding direction. As a result, the upper end portion of the cap body 8 opens in a substantially elliptical shape as the upper opening portion 8a of the cap body 8.

[0024] The pair of grooves 16 are disposed symmetrically to each other at opposing positions on peripheral wall 13. Each groove 16 is cut out in the vertical direction with a constant width corresponding to spout 15.

[0025] An inclined surface 17 inclined from the upper end of the peripheral wall portion 13 toward the expanded wall portion 14 is provided around the entire periphery on the inside of the cap body 8. On the other hand, an upper flange portion 18 protruding in the radially expanding direction from between the peripheral wall portion 13 and the expanded wall portion 14 is provided around the entire periphery on the outside of the cap body 8.

[0026] A first male screw portion 19 is provided on the outer peripheral surface of the peripheral wall portion 13 (cap body 8). The first male screw portion 19 is composed of a screw thread that spirally protrudes upward from the lower end side of the peripheral wall portion 13. As a result, the cap body 8 is detachably attached to the container body 2 by screwing together the screw threads that constitute the first female screw portion 6 and the first male screw portion 19 when the cap body 8 is fitted into the inside of the container body 2 from the upper opening 2d of the container body 2.

[0027] In addition, when the cap body 8 is attached to the mouth-neck portion 2c of the container body 2, the upper flange portion 18 abuts against the upper end portion of the mouth-neck portion 2c, thereby covering the upper opening 2d of the container body 2.

[0028] A waterproof gasket 20 is detachably attached to the outer periphery of the lower end side of the peripheral wall portion 13 (cap body 8). The waterproof gasket 20 is a ring-shaped sealing member that seals the gap between the inside of the container body 2 and the cap body 8, and is made of an elastic material such as heat-resistant rubber, elastomer, etc., such as silicone rubber.

[0029] A lower flange portion 21 is provided on the outer periphery of the lower end side of the cap body 8 so as to protrude in the radially expanding direction. Meanwhile, a ring-shaped fitting recess 20a is provided around the entire periphery on the inner periphery surface of the watertight gasket 20. The watertight gasket 20 is fitted around the outer periphery of the lower end side of the cap body 8 with the lower flange portion 21 fitted into the fitting recess 20a.

[0030] Further, an elastic flange portion 20b is provided on the outer periphery of the watertight gasket 20. The elastic flange portion 20b has a shape that protrudes downward from the upper end of the outer periphery of the watertight gasket 20 while curving.

[0031] When the cap body 8 is attached to the container body 2, the waterproof gasket 20 is in close contact with the entire periphery of the protruding portion 7 while the elastic flange portion 20b is elastically deformed. This makes it possible to seal the gap between the protruding portion 7 and the cap body 8.

[0032] On the other hand, the watertight gasket 20 can be removed from the outer periphery on the lower end side of the cap body 8 by elastically deforming (pulling and stretching) the watertight gasket 20 itself. This allows the watertight gasket 20 and the cap body 8 to be washed separately, and the space between the watertight gasket 20 and the cap body 8 can be kept hygienic.

[0033] The inner peripheral surface of the peripheral wall portion 13 (cap body 8) is provided with a second female screw portion 22. The second female screw portion 22 is composed of a screw thread that protrudes downward from the upper end side of the peripheral wall portion 13 in a spiral shape.

[0034] The lid body 9 opens and closes the liquid passage hole 11, and has an upper lid 23 and an inner plug 24 made of a heat-resistant resin such as PP.

[0035] The top lid 23 is a portion that covers the top of the cap body 8, and is formed in a flat plate shape having a generally elliptical shape corresponding to the top opening 8a of the cap body 8. A grip portion 25 is provided on the top of the top lid 23. The grip portion 25 is a portion that is gripped by the user, and is provided so as to protrude in a fin-like shape from the center of the top surface of the top lid 23.

[0036] The inner plug 24 is a part that is fitted inside the cap body 8, has a generally cylindrical shape with a bottom, and is attached integrally to the center of the lower surface of the upper lid 23 by welding or the like. A heat insulating material S made of, for example, urethane foam resin or the like is disposed inside the inner plug 24 as a heat insulating layer. Also, the heat insulating layer may be air (void) instead of the heat insulating material S described above.

[0037] A second male screw portion 26 is provided on the outer circumferential surface of the inside plug 24. The second male screw portion 26 is composed of a screw thread that spirally protrudes upward from the lower end side of the outer circumferential surface of the inside plug 24. As a result, the lid body 9 is detachably attached to the cap body 8 by screwing together the screw threads that constitute the second female screw portion 22 and the second male screw portion 26, while being fitted into the inside of the cap body 8 through the upper opening 8a of the cap body 8.

[0038] In addition, the second female screw portion 22 and the second male screw portion 26 are double-threaded threads that are complementary to each other. When a double-threaded thread is used, the lid body 9 can be attached to and detached from the cap body 8 with a small rotation operation (about 450° in this embodiment).

[0039] A lid gasket 27 is detachably attached to the outer periphery of the lower end side of the inner plug 24. The lid gasket 27 is a ring-shaped sealing member that seals the space between the periphery of the liquid passage hole 11 in the bottom wall portion 12 (the inside of the cap body 8) and the inner plug 24, and similar to the watertight gasket 20, is made of an elastic material such as a heat-resistant rubber such as silicone rubber or an elastomer.

[0040] A ring-shaped fitting groove 24a is provided around the entire periphery on the outer periphery of the lower end side of the inside plug 24. The lid packing 27 is fitted into this fitting groove 24a around the entire periphery.

[0041] When the lid body 9 is attached to the cap body 8, the lid gasket 27 elastically deforms and comes into close contact with the entire periphery of the liquid passage hole 11. This makes it possible to seal the gap between the liquid passage hole 11 (inside of the cap body 8) and the inner plug 24 (lid body 9).

[0042] On the other hand, the lid gasket 27 can be removed from the outer periphery on the lower end side of the inner plug 24 by elastically deforming (pulling and stretching) the lid gasket 27 itself. This allows the lid gasket 27 and the lid body 9 to be washed separately, and the space between the lid gasket 27 and the lid body 9 can be kept hygienic.

[0043] A pair of symmetrical rib walls 28 are provided at opposing positions on the inside plug 24. Each rib wall 28 is located above the second male thread portion 26, and is provided to extend circumferentially from the outer circumferential surface of the inside plug 24 and protrude in the radially expanding direction. Moreover, the rib wall 28 is provided to protrude in the radially expanding direction beyond the threads that form the second male thread portion 26. Furthermore, the rib wall 28 is provided to extend circumferentially wider than the width of the groove portion 16.

[0044] Strainer member 10 constitutes a tea strainer, and has strainer body 29 that is substantially cylindrical and has a bottom, and is made of heat-resistant resin such as PP. The inner diameter of strainer body 29 (strainer member 10) is the same as the inner diameter of liquid passage hole 11.

[0045] A plurality of slits 29a extending in the vertical direction are arranged in the vertical and circumferential directions around the periphery of strainer body 29. In addition, a plurality of slits 29a extending in the circumferential direction are arranged concentrically in the bottom of strainer body 29.

[0046] The upper end of strainer body 29 is opened in a circular shape as upper opening 29b of strainer body 29. Furthermore, flange portion 29c is provided at the upper end of strainer body 29 so as to protrude in the radially expanding direction. Furthermore, inclined surface 29d is provided at the upper end of strainer body 29, inclined downward toward the tip of flange portion 29c.

[0047] On the other hand, a contact surface 8b that comes into contact with the inclined surface 29d is provided at the lower end of the cap body 8. The contact surface 8b is provided at an incline all around the inside of the lower tube portion 8c that protrudes downward from the periphery of the liquid passage hole 11 of the bottom wall portion 12.

[0048] The tea strainer member 10 is attached to the cap body 8 so as to be freely rotatable, with the flange portion 29c being sandwiched between the lower end portion (lower cylinder portion 8c) of the cap body 8 and the water stop gasket 20.

[0049] In the cap unit 1 of this embodiment having the above-mentioned configuration, when the strainer member 10 is attached to the above-mentioned cap body 8, the strainer member 10 is rotated and pressed against the bottom of the cap body 8, whereby the water-stopping gasket 20 is elastically deformed, and the flange portion 29c can be easily sandwiched between the lower end portion (lower tube portion 8c) of the cap body 8 and the water-stopping gasket 20. This makes it possible to attach the strainer member 10 to the cap body 8 easily and stably.

[0050] On the other hand, in the cap unit 1 of this embodiment, when the cap body 8 is removed from the container body 2, the tea strainer member 10 can be easily attached and detached to the cap body 8, and it is also possible to attach the cap unit 1 to the container body 2 and use it with the tea strainer member 10 removed. Furthermore, by making the inner diameter of the tea strainer member 10 the same as the inner diameter of the liquid passage hole 11, it is easy to put tea leaves in and take them out of the tea strainer member 10. This makes it possible to improve the washability of the tea strainer member 10.

[0051] In the capped container 100 including the cap unit 1 of this embodiment, from a state in which the lid body 9 closes the liquid passage hole 11 as shown in Figures 1 and 3, by rotating the lid body 9 in the opening direction through a predetermined angle range (about 90°), the pair of pouring spouts 15 and the liquid passage hole 11 are opened as shown in Figures 2 and 4. By tilting the container body 2 from this state, it is possible to pour the beverage (liquid) in the container body 2 from the liquid passage hole 11 through the groove portion 16 and the pouring spout portion 15 into a cup or the like without removing the lid body 9 from the cap body 8.

[0052] In cap unit 1 of the present embodiment, when the pair of pouring portions 15 and liquid passage holes 11 described above are open, the pair of rib walls 28 face the pair of pouring portions 15. In addition, when the pair of rib walls 28 face the pair of pouring portions 15, both sides of rib wall 28 sandwiching pouring portion 15 therebetween are at a height position facing inclined surface 17.

[0053] As a result, in the cap unit 1 of this embodiment, when the beverage (liquid) in the container body 2 is poured out through the groove portion 16 and the spout portion 15, the beverage hits the rib wall 28, thereby restricting and stabilizing the flow rate of the beverage flowing out through the groove portion 16 and the spout portion 15. As a result, in the cap unit 1 of this embodiment, it is possible to prevent pulsation from occurring in the beverage, causing the beverage to splash around, or to prevent the beverage from draining properly.

[0054] As described above, the capped container 100 including the cap unit 1 of the present embodiment described above can further improve usability.

[0055] 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 addition to the above-mentioned configuration, the cap unit 1 may be configured to have an inner lid 30 attached thereto as shown in Fig. 8 and Fig. 9. Fig. 8 is a perspective view showing a state in which the inner lid 30 is attached to the cap unit 1. Fig. 9 is a perspective view showing the configuration of the inner lid 30.

[0056] The inner lid 30 is made of a heat-resistant resin such as polypropylene (PP) and has a disk shape corresponding to the liquid passage hole 11. The inner lid 30 is provided with a plurality of slits 30a extending in one direction in a plane and arranged in a direction perpendicular to the one direction. Furthermore, a pair of legs 30b are provided on the outer periphery of the lower surface side of the inner lid 30. The pair of legs 30b are provided at mutually opposing positions around the periphery of the inner lid 30, extending in the circumferential direction of the inner lid 30 and protruding downward.

[0057] The inner lid 30 is detachably attached to the cap body 8 by fitting a pair of legs 30b into an upper opening 29b of the tea strainer body 29.

[0058] In a cap unit 1 equipped with such an inner lid 30, the inner lid 30 can prevent the tea leaves contained in the tea strainer member 10 from flowing out through the liquid passage hole 11 together with the beverage (liquid) in the container body 2.

[0059] In addition, the above-mentioned cap unit 1 is not necessarily limited to the configuration of the tea strainer member 10 in which the above-mentioned tea strainer body 29 has a plurality of slits 29a, and it is also possible to use, for example, a tea strainer member 10 in which the tea strainer body 29 has a plurality of holes formed in a mesh pattern.

[0060] In the above embodiment, a capped container 100 having heat and cold insulation functions is exemplified by the 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.
