[Figure 3] 1 is a side cross-sectional view illustrating a lid portion of a beverage container according to an embodiment. [Figure 4] FIG. 10 is a diagram illustrating a second position. DETAILED DESCRIPTION OF THE INVENTION

[0009] Beverage containers according to embodiments will be described in detail below with reference to the drawings.

[0010] 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. <Embodiment>

[0011] Fig. 1 is a perspective view showing a beverage container according to an embodiment, Fig. 2 is a side cross-sectional view of the beverage container according to an embodiment, and Fig. 3 is a side cross-sectional view illustrating a lid of the beverage container according to an embodiment. The beverage container 1 of the embodiment has a container body 2 and a lid portion 3.

[0012] The container body 2 has, for example, a vacuum double-wall structure, and includes an opening 21 (see FIG. 2) that serves as an inlet / outlet for the beverage inside when the lid 3 is not attached, and a narrowed portion 22 with a smaller radius than the opening 21. A threaded portion 23 that threadably engages with the lid 3 is provided on the outer periphery of the opening 21. The lid portion 3 has a lid main body 31, a flow path portion 32, an upper lid 33, and a fixing portion . 3, the lid main body 31 has a threaded portion 311, a shaft portion 312, and an engaged portion 313. The threaded portion 311 is detachably threadedly engaged with the threaded portion 23.

[0013] The shaft 312 is disposed at the end on the rear side (opposite the drinking spout) of the lid body 31. The shaft 312 has a shaft pin 312a and a shaft hole 312b through which the shaft pin 312a passes. The engaged portion 313 engages with an engaging portion of the flow path portion 32, which will be described later.

[0014] The flow path section 32 is provided with a drinking spout through which a user drinks a beverage. The flow path section 32 is detachably attached to the lid body 31. By attaching the flow path section 32 to the lid body 31, the beverage stored inside the container body 2 passes through the flow path section 32 and flows out. The flow path section 32 has an engagement section 321, a packing 322, and a narrowed section 323. The engaging portion 321 is supported by the lid body 31 by engaging with the engaged portion 313 .

[0015] The packing 322 is disposed at a location corresponding to the narrowed portion 22 when the engaging portion 321 engages with the engaged portion 313. The packing 322 prevents the beverage from flowing out from the side of the narrowed portion 22.

[0016] A water stopping portion (described later) that stops the flow of the beverage at a first position (described later) is disposed in narrowed portion 323. By providing narrowed portion 323, the area that is stopped is reduced.

[0017] The top lid 33 is pivotally supported by a shaft 312. The top lid 33 rotates around a shaft pin 312a. A lid-opening spring (not shown) attached to the shaft 312 biases the top lid 33 in a direction that separates the top lid 33 from the flow path section 32 (counterclockwise in FIG. 3).

[0018] 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 312a 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 waterproof portion 331 . The waterproof portion 331 has a resin member 331a and an elastic member 331b.

[0019] Resin member 331a is a cylindrical member having a hollow portion 331a0, and has end portion 331a1 adhered to rear surface 332 of top cover 33 and adhesive portion 331a2 to which elastic member 331b is adhered. The adhesive portion 331a2 has a stepped shape.

[0020] The elastic member 331b blocks the end (inner circumferential surface) 323a of the narrowed portion 323 at the first position, thereby preventing the beverage stored inside the container body 2 from flowing out.

[0021] Elastic member 331b is a cylindrical member with hollow portion 331b1 and has a shape corresponding to adhesive portion 331a2. Hollow portion 331b1 is connected to hollow portion 331a0. Elastic member 331b is bonded to adhesive portion 331a2 so as to surround the periphery of adhesive portion 331a2, thereby being molded integrally with resin member 331a. Because adhesive portion 331a2 has a stepped shape, the adhesive area is larger than, for example, a tapered adhesive portion, and the adhesive strength is increased.

[0022] The material of the resin member 331a is not particularly limited, but may be, for example, polypropylene, etc. The elastic member 331b is not particularly limited, but may be, for example, silicone rubber, etc.

[0023] By providing elastic member 331b with hollow portion 331b1, when elastic member 331b closes end 323a of narrowed portion 323 in the first position, hollow portion 331b1 is slightly deformed when the surface of elastic member 331b is pressed by end 323a, weakening the repulsive force of the surface of elastic member 331b against end 323a. Therefore, even when elastic member 331b molded integrally with resin member 331a is used, the force applied when closing the lid can be reduced.

[0024] The fixing part 34 is disposed on the front side (drinking spout side) of the lid body 31. The fixing part 34 fixes the top lid 33 to the lid body 31. When the top lid 33 is fixed to the lid body 31 by the fixing part 34, the water stop part 331 provided on the top lid 33 keeps the inside of the container body 2 watertight, and the beverage inside the container body 2 does not spill out. The fixed portion 34 has a wall portion 34a and an operating member 34b (see FIG. 1). The wall portion 34a protrudes outward from the side surface of the lid body 31 and has a U-shape in plan view. The user can rotate the upper cover 33 by operating the operating member 34b.

[0025] The top cover 33 has a hook receiving portion (engaged portion) 333 onto which a hook portion (engaging portion) 34b1 (see FIG. 3) provided on the upper end portion of the operating member 34b is hooked. The top cover 33 also has a wall portion 334 (see FIG. 1) that surrounds the hook receiving portion 333. The wall portion 34a and the wall portion 334 surround the periphery of the operating member 34b. A shaft portion 35 is formed inside the wall portion 34a. The shaft portion 35 has a shaft pin 35a and a shaft hole portion 35b through which the shaft pin 35a is inserted.

[0026] The operating member 34b is pivotally supported by a shaft 35. The operating member 34b rotates around a shaft pin 35a. The operating member 34b is biased in the counterclockwise direction in FIGS. 2 and 3 by a cover-opening spring (not shown) attached to the shaft 35.

[0027] To put a beverage into this container body 2, grasp the container body 2 and rotate the lid part 3 counterclockwise to loosen and remove the screw, and then pour the beverage into the container body 2. Then, grasp the container body 2 and rotate the lid part 3 clockwise to attach it.

[0028] When a user wants to drink a beverage, the user presses the lower half of the surface of the operating member 34b with a finger, which releases the lock formed by the hook portion 34b1 and the hook receiving portion 333. This moves the top lid 33 to the second position. FIG. 4 is a diagram illustrating the second position.

[0029] By releasing the lock, the top lid 33 rotates counterclockwise around the pivot pin 312a as shown in Figure 4 by the lid-opening spring (not shown) attached to the pivot part 312, and enters the open state. The user can then drink the beverage in the container body 2.

[0030] As described above, the beverage container 1 of the embodiment comprises a container body 2, a lid body 31 attached to the container body 2, a flow path section 32 that forms a flow path through which the beverage stored in the container body 2 flows out, an upper lid 33 that is rotatably attached to the lid body 31 and can take a first position that stops water from entering the flow path section 32 and a second position that can be rotated to open the flow path section 32, and a lid section 3 that has a fixing section 34 that supports a part of the upper lid 33 to fix the upper lid 33 and releases the fixation of the upper lid 33 by releasing the support, and the upper lid 33 has an elastic member 331b that has a hollow hollow section 331b1 and that elastically deforms when the hollow section 331b1 is in the first position to block the flow path section 32, and a resin member 331a that is adhered to the elastic member 331b and supports the elastic member 331b.

[0031] As described above, by providing elastic member 331b with hollow portion 331b1, when elastic member 331b closes end 323a of narrowed portion 323 in the first position, hollow portion 331b1 is slightly deformed when the surface of elastic member 331b is pressed by end 323a, weakening the repulsive force of the surface of elastic member 331b against end 323a. Therefore, even when elastic member 331b molded integrally with resin member 331a is used, the force applied when closing the lid can be reduced.

[0032] In this embodiment, elastic member 331b closes end 323a of narrowed portion 323. However, elastic member 331b may close other portions of flow path portion 32.

[0033] In addition, in this embodiment, the elastic member 331b and the resin member 331a are integrally molded by adhering the elastic member 331b to the resin member 331a, but this is not limitative, and for example, the elastic member 331b may be welded to the resin member 331a.

[0034] While the beverage container of the present invention has been described above based on the illustrated embodiment, the present invention is not limited to this, and the configuration of each part can be replaced with any configuration having a similar function. Furthermore, any other components or steps may be added to the present invention. Furthermore, the present invention may be a combination of any two or more configurations (features) of the above-described embodiments. [Explanation of symbols]
