[0008] Beverage containers according to embodiments will be described in detail below with reference to the drawings.

[0009] In order to facilitate understanding of the invention, the position, size, shape, range, etc. of each component shown in the following drawings may not represent the actual position, size, shape, range, etc. Therefore, the present invention is not necessarily limited to the position, size, shape, range, etc. disclosed in the drawings, etc. In the embodiments, elements expressed in the singular include the plural unless otherwise clearly indicated in the context. First Embodiment

[0010] Fig. 1 is a perspective view showing a beverage container according to a first embodiment, Fig. 2 is a side cross-sectional view of the beverage container according to the first embodiment, and Fig. 3 is a side cross-sectional view illustrating a lid of the beverage container according to the first embodiment. The beverage container 1 of the embodiment has a container body 2 and a lid portion 3.

[0011] The container body 2 has, for example, a vacuum double-wall structure, and as shown in Figure 2, has a first cylindrical portion 21 for storing the beverage and a second cylindrical portion 22 with a smaller diameter than the first cylindrical portion 21. An opening 22a is provided at the end of the second cylindrical portion 22, which serves as an inlet / outlet for the beverage when the lid portion 3 is not attached. In addition, a narrowed portion 23 with a smaller diameter than the second cylindrical portion 22 is provided between the first cylindrical portion 21 and the second cylindrical portion 22. The second cylindrical portion 22 has an inner periphery provided with a threaded portion 24 that is threadably engaged with the lid portion 3 . Fig. 4 is an exploded view illustrating the lid of the beverage container according to the first embodiment, and Fig. 5 is an exploded cross-sectional view illustrating the lid of the beverage container according to the first embodiment. The lid portion 3 has a plug body 31, a flow path portion 32, an upper lid 33, and a fixing portion . The plug 31 is attached to the container body 2 . As shown in FIG. 3, the plug 31 has a shaft portion 311 that supports the top cover 33 .

[0012] The stem 311 is disposed at the end on the back side (opposite the drinking spout, which will be described later) of the stopper 31. The stem 311 has a stem 311a and a stem hole 311b through which the stem 311a passes. The flow path portion 32 has a flow path 321 , a hollow portion 322 , a heat insulating portion 323 , a water blocking packing 324 , a plug packing support portion 325 , and a plug packing 326 .

[0013] In this embodiment, the flow path 321 is formed integrally with the stopper 31. The flow path 321 in this embodiment is cylindrical, with most of it located within the second cylindrical portion 22, and serves as a flow path through which the beverage stored in the first cylindrical portion 21 flows out. That is, the beverage stored inside the first cylindrical portion 21 passes through the flow path 321 and flows out to the outside. The flow path 321 is provided with a drinking spout 321a through which the user drinks the beverage. The flow path 321 also has a circular opening 321b in which a waterproof gasket, which will be described later, is placed.

[0014] The hollow portion 322 is disposed outside the flow path 321 and has an annular cavity with an open bottom. A threaded portion 322a that detachably threads onto the threaded portion 24 is provided on the outer wall of the hollow portion 322.

[0015] Heat insulating portion 323 is disposed inside hollow portion 322. Examples of materials constituting heat insulating portion 323 include a material that is less heat-transmitting than the material forming hollow portion 322, such as polyurethane resin.

[0016] By placing the insulating portion 323 inside the hollow portion 322, a higher insulating effect can be obtained than when the hollow portion 322 is filled with the same material as the hollow portion 322, and temperature changes of the beverage stored in the container body 2 can be suppressed.

[0017] The waterproof gasket 324 is elastic and is disposed at the contact portion between the flow path 321 and the stopper gasket support portion 325, and prevents the beverage from flowing into the cavity portion 322.

[0018] Stopper packing support part 325 is disposed below flow path 321 and hollow part 322. Stopper packing support part 325 is bonded to opening end 322b of hollow part 322 at bonding part 325a. Stopper packing support part 325 covers lower end 321c of flow path 321 and the bottom of hollow part 322.

[0019] Stopper gasket 326 is supported by stopper gasket support portion 325. Stopper gasket 326 is disposed at a position corresponding to narrowed portion 23 when stopper 31 is attached to container body 2. Stopper gasket 326 prevents beverage from leaking out from the side of narrowed portion 23.

[0020] As described above, the top lid 33 is supported by the shaft portion 311. The top lid 33 rotates around the shaft pin 311a in the clockwise and counterclockwise directions in Fig. 3. The top lid 33 is biased in a direction (clockwise direction in Fig. 3) that separates the top lid 33 from the flow path portion 32 by a lid-opening spring (not shown) attached to the shaft portion 311.

[0021] The upper lid 33 can be placed in a first position where it stops water from entering the flow path portion 32, and in a second position where it rotates around the pivot pin 311a to open the flow path portion 32. In Figures 2 and 3, the upper lid 33 is placed in the first position. The top cover 33 has a resilient gasket 331 for the drinking spout. In the first position, the drinking spout gasket 331 closes the end of the opening 321b.

[0022] A fixing part 34 for fixing the top lid 33 to the stopper 31 is provided on the front side (the drinking spout 321a side) of the stopper 31. When the top lid 33 is fixed to the stopper 31 by the fixing part 34, the inside of the container body 2 is kept watertight by the drinking spout gasket 331 provided on the top lid 33, and the beverage inside the container body 2 does not spill out. The fixing portion 34 has a wall portion 34a, a button 34b, and a locking member 34c. The wall portion 34a protrudes outward from the side surface of the plug 31, and in this embodiment has a U-shape when viewed from the front. With the locking member 34c separated from the top cover 33, the user can rotate the top cover 33 by operating the button 34b.

[0023] The top cover 33 has a hook receiving portion (engaged portion) 332 that hooks onto a hook portion (engaging portion) 34b1 (see FIG. 3) provided on the upper end of the button 34b. The top cover 33 also has an arc-shaped wall portion 333 formed to surround the hook receiving portion 332. The shape of the wall portion 333 is not limited to an arc shape. The wall portion 34a is provided with circular holes 34a1, 34a1 facing each other and holes 34a2, 34a2 facing each other.

[0024] The button 34b is supported by a bearing portion formed by the hole portion 34a1 and the pivot pin 34a3, so that the button 34b can swing around the bearing portion.

[0025] The shape of the button 34b from the center to the bottom is a shape that corresponds to the wall portion 34a. The button 34b from the center to the bottom is disposed within the internal space formed by the wall portion 34a.

[0026] When the user presses the slightly curved portion near the center of the button 34b, the hook receiving portion 332 is disengaged from the hook portion 34b1 of the button 34b, thereby releasing the lock of the top cover 33. The locking member 34c has an engaging portion 34c1 and a shaft portion 34c2.

[0027] The inside of the engaging portion 34c1 has a shape (substantially U-shaped in this embodiment) that corresponds to the wall portion 333. The engaging portion 34c1 surrounds the arc-shaped wall portion 333 when positioned upward. The shaft portions 34c2, 34c2 extend inward from both ends of the engaging portion 34c1 and face each other.

[0028] The shafts 34c2 are inserted into the holes 34a2, respectively. The locking member 34c rotates around the shafts 34c2. The shafts 34c2 can also be removed from the holes 34a2. Next, the operation of moving the beverage container 1 from the first position to the second position will be described.

[0029] The user rotates top cover 33 counterclockwise around shaft 311 to move it in a direction that covers opening 321b. This causes hook receiving portion 332 to push the sloped upper surface of hook portion 34b1 outward. Hook portion 34b1 moves over hook receiving portion 332 and engages with hook receiving portion 332, locking top cover 33 so that it does not open (first lock).

[0030] Next, the user grasps engaging portion 34c1 with his / her fingers and turns it upward, and locks it by hooking engaging portion 34c1 onto the upper edge of wall portion 333 of top cover 33. This prevents top cover 33 from opening even if the user operates button 34b (second lock).

[0031] To put a beverage into the container body 2, the lid 3 is unscrewed and removed from the container body 2, and the beverage is poured into the container body 2. Thereafter, the lid 3 is attached to the container body 2, and the first lock and second lock are performed to double lock the top lid 33. To open the top cover 33, the user performs the reverse of the above-described operations. That is, the user flips the engaging portion 34c1 downward to release the second lock.

[0032] Next, the user presses the lower half of the surface of button 34b with a finger. This releases the first lock formed by hook portion 34b1 and hook receiving portion 332. When the first lock is released, a lid-opening spring (not shown) attached to shaft portion 311 causes top lid 33 to spring upward and open as shown in FIG. 1. The user can then drink the beverage in container body 2.

[0033] As described above, the beverage container 1 of the embodiment includes a container body 2 having a cylindrical first cylindrical portion 21 with an opening 22a for storing a beverage, a flow path portion 32 including a flow path 321 disposed inside the opening 22a and through which the beverage stored in the first cylindrical portion 21 flows out, a hollow portion 322 surrounding the flow path 321 and having a cavity, and an insulating portion 323 disposed within the hollow portion 322 and having a lower thermal conductivity than the material forming the hollow portion 322, a stopper 31 attached to the container body 2 and supporting the flow path portion 32, and a lid 3 having an upper lid 33 rotatably attached to the stopper 31 and capable of assuming a first position that seals the flow path 321 and a second position that opens the flow path 321 when rotated. By disposing the insulating portion 323 within the hollow portion 322, temperature changes of the beverage stored in the container body 2 can be suppressed. <Second embodiment> Next, a beverage container according to a second embodiment will be described. The beverage container of the second embodiment will be described below, focusing on the differences from the first embodiment, and a description of the same points will be omitted.
