[0008] [Figure 1] 1 is a perspective view showing a beverage container according to an embodiment. [Figure 2] 1 is a side cross-sectional view of a beverage container according to an embodiment. [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. [Figure 5] FIG. 4 is a cross-sectional view showing a beverage container according to a second embodiment. 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] The resin member 331a has an end 331a1 adhered to the rear surface 332 of the top lid 33, an adhesive portion 331a2 to which the elastic member 331b is adhered, and a water blocking surface 331a3 that, together with the elastic member 331b, blocks the flow of beverages. The adhesive portion 331a2 has a stepped shape. The elastic member 331b closes the end (inner circumferential surface) 323a of the narrowed portion 323 at the first position.

[0020] Elastic member 331b is a cylindrical member and has a shape corresponding to adhesive portion 331a2. 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 therefore greater.

[0021] Water stopping surface 331a3 is flat and closes the center of narrowed portion 323. This resin member 331a (at least water stopping surface 331a3) has better water repellency (higher water repellency) than elastic member 331b, and water droplets adhering to water stopping surface 331a3 are repelled (quickly detached even if they do adhere). The material of the resin member 331a is not particularly limited, but may be, for example, polypropylene.

[0022] 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.

[0023] 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.

[0024] 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.

[0025] 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.

[0026] 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.

[0027] By releasing this lock, the lid-opening spring (not shown) attached to the shaft 312 rotates the top lid 33 counterclockwise around the shaft pin 312a as shown in FIG. 4, to the open state. The user can then drink the beverage in the container body 2. At this time, no water droplets adhere to the water-stopping surface 331a3, which prevents water droplets from splashing when the top lid 33 rotates.

[0028] 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 forming a flow path through which the beverage stored in the container body 2 flows out, an upper lid 33 rotatably attached to the lid body 31 and capable of taking a first position in which the flow path section 32 is watertight and a second position in which the flow path section 32 is opened by rotation, and a lid section 3 having a fixing section 34 which 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 comprises an elastic member 331b which blocks the end 323a of the narrowed section 323 in the first position, and a resin member 331a which is adhered to the elastic member 331b and blocks the central part of the narrowed section 323 with a water-stopping surface 331a3 and has better water repellency than the elastic member 331b. Therefore, water droplets adhering to the water-stopping surface 331a3 are repelled, making it less likely that water droplets will adhere to the water-stopping surface 331a3, and preventing water droplets from splashing even when the top cover 33 is rotated forcefully. In addition, the flat surface of the water-stopping surface 331a3 also contributes to improving water repellency.

[0029] In the present embodiment, elastic member 331b closes end 323a of narrowed portion 323, and water blocking surface 331a3 closes the center of narrowed portion 323. However, the position where elastic member 331b and resin member 331a close may be other positions in flow path portion 32. <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. FIG. 5 is a cross-sectional view showing a beverage container according to the second embodiment. A beverage container 1a according to the second embodiment shown in FIG. 5 differs from that of the first embodiment in the configuration of the water blocking surface. The shape of the water blocking surface 331a4 of the beverage container 1a is a curved surface, which further reduces adhesion of water droplets to the water blocking surface 331a4.

[0030] 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]
