[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. <Embodiment> FIG. 1 is a diagram showing a beverage container according to an embodiment.

[0010] Figures 1 and 2 are perspective views showing a beverage container according to an embodiment. Figure 3 is a side cross-sectional view of a lid of the beverage container according to an embodiment. Parts of the beverage container are not shown in Figure 3. In Figure 3, the left side of the page is referred to as the "near side" and the right side is referred to as the "rear side." The beverage container 10 of the embodiment has a container body 1 and a lid portion 2.

[0011] As shown in Figure 3, the container body 1 has, for example, a cylindrical, bottomed, vacuum double-wall structure and includes a storage section 11 for storing a beverage (not shown) and an opening 12 that allows the beverage to flow into or out of the storage section 11. A threaded section 13 that threadably engages with the lid section 2 is provided on the outer side of the opening 12, slightly below the plane of the drawing. In addition, a constricted section 14 is provided between the storage section 11 and the opening 12, the constricted section having a narrower flow path than the storage section 11 and the opening 12. The container body 1 may be made of, for example, stainless steel. The lid portion 2 has a lid body 21, an upper lid 22, a drinking spout part 23, and a fixing portion 24. FIG. 4 is an exploded perspective view of the lid portion. As shown in FIGS. 3 and 4, the lid body 21 has an opening 210, a screw-fitting portion 211, and a shaft portion 212.

[0012] The shaft portion 212 is disposed at the end portion on the rear side (opposite the side where the fixing portion 24 is provided) of the lid main body 21. The shaft portion 212 has a shaft pin 212a and a shaft hole portion 212b into which the shaft pin 212a is inserted.

[0013] The drinking spout part 23 is located inside the opening 210. Support parts 210a and 210b that support the drinking spout part 23 are provided on the front and back sides of the opening 210, respectively. The support portion 210a is a portion where the opening end on the front side of the opening portion 210 is cut out, and is a portion that supports the contact portion (described later) of the drinking spout part 23. An engaged portion 213 is provided near the support portion 210a. The engaged portion 213 is provided at a distance from the support portion 210a, separated by a step. The support portion 210b is disposed in a portion of the opening 210 where a part of the inner side is cut away. The threaded portion 211 is detachably threaded onto the threaded portion 13 . The top cover 22 has an axial hole portion 221 and a waterproof packing 222 .

[0014] The shaft hole portion 221 communicates with the shaft hole portion 212b, and the top cover 22 is pivotally supported by the shaft pin 212a when the shaft pin 212a is inserted into the shaft hole portion 221. The top cover 22 rotates around the shaft pin 212a as a central axis.

[0015] The top lid 22 can be in a first position (see FIG. 1) where a portion of it is fixed to the fixing portion 24, and in a second position (see FIG. 2) where it rotates around the pivot pin 212a as the central axis to open the portion through which the beverage flows out. The position of the top lid 22 in FIG. 1 is the first position. The position of the top lid 22 in FIG. 2 is the second position. In the first position, the area from which the beverage flows (in this embodiment, the drinking spout, which will be described later) is covered, preventing the user from drinking the beverage, whereas in the second position, the user can drink the beverage. When in the first position, the water blocking packing 222 blocks the end (inner peripheral surface) of a narrowed portion (described later) to block the beverage and stop the flow of water.

[0016] 3, the upper cover 22 has a hook receiving portion (engaged portion) 223 onto which a hook portion (engaging portion: described later) provided at the upper end of the fixing portion 24 is hooked. Also, as shown in FIG. 1, the upper cover 22 has an arc-shaped wall portion 224 formed so as to surround the hook receiving portion 223. Note that the shape of the wall portion 224 is not limited to an arc shape.

[0017] The spout part 23 is detachably attached to the support parts 210a and 210b. When the lid body 21 with the spout part 23 attached thereto is attached to the container body 1, the beverage inside the container body 1 flows out from the spout part 23.

[0018] As shown in FIGS. 3 and 4, the drinking spout part 23 has a drinking spout 23a, an engaging portion (protrusion) 23bb, a contact portion 23c, a rear supported portion 23d, a narrowed portion 23e, and a packing 23f. FIG. 5 is a diagram illustrating the positional relationship between the engaging portion and the engaged portion. When the drinking spout part 23 is attached to the lid body 21, the engaging part 23b abuts against the engaged part 213. In side view, a gap P is formed between the inclined surface of the engaging portion 23b and the upper surface of the support portion 210a. The engaged portion 213 has a portion 213a that engages with the top of the engaging portion 23b, and a portion 213b that is provided contiguous to the portion 213a and is located on the opposite side of the engaging portion 23b.

[0019] The contact portion 23c comes into contact with the support portion 210a when the drinking spout part 23 is attached to the lid body 21. In the first position, the contact portion 23c may be spaced apart from the support portion 210a. As shown in FIG. 3, when the drinking spout part 23 is attached to the lid body 21, the rear supported part 23d is supported by the supporting part 210b. The narrowed portion 23e has a waterproof packing 222 disposed at the first position. The provision of the narrowed portion 23e reduces the blocking area.

[0020] Gasket 23f is disposed on the side of narrowed portion 14. When lid 2 is attached to container body 1, gasket 23f is located on the side of narrowed portion 14, stopping the flow of beverage in reservoir 11 so that the beverage does not enter above gasket 23f.

[0021] The material of the packing 23f is not particularly limited, but examples thereof include silicone rubber and thermoplastic elastomer. The fixing part 24 fixes the top lid 22 to the lid body 21. The fixing part 24 is provided on the front side (the drinking spout side) of the lid body 21. As shown in FIG. 1, the fixing portion 24 has a wall portion 24a, an operating member 24b, and a locking member 24c.

[0022] Wall portion 24a is molded integrally with lid main body 21. Wall portion 24a protrudes outward from the side surface of lid main body 21 and is U-shaped in plan view. Wall portion 24a forms a wall portion that is continuous with wall portion 224 at the first position. When the operating member 24b is in an unlocked position (described later), it can be operated to release the fixation of the top cover 22 and move the top cover 22 from the first position to the second position.

[0023] As shown in FIG. 2, the side surface of the wall portion 24a is provided with a circular hole portion 24a1, a shaft pin 24a2 to be inserted into the hole portion 24a1, and a hole portion 24a3 to house the shaft portion of the locking member 24c. The operating member 24b is partially disposed within the wall portion 24a. As shown in FIG. 3, the operating member 24b has a hook portion 24b1, a shaft hole portion 24b2, and a pressing portion 24b3. The hook portion 24b1 abuts against the hook receiving portion 223 at the first position.

[0024] A pivot pin 24a2 is inserted into the shaft hole portion 24b2. The operation member 24b is pivotally supported by the pivot pin 24a2 when the pivot pin 24a2 is inserted into the shaft hole portion 24b2. This allows the operation member 24b to rotate (swing) around the pivot pin 24a2 as a central axis. The pressing portion 24b3 has a step, and is pressed by the user with the thumb or the like when moving the top cover 22 from the first position to the second position.

[0025] A coil spring (not shown) is provided between the rear surface of the pressing portion 24b3 and the bottom surface of the groove of the wall portion 24a, for biasing the operating member 24b in a direction rotating clockwise in FIG.

[0026] The locking member 24c can take a locked position in which the top cover 22 will not move from the first position to the second position even when the operating member 24b is operated, and an unlocked position in which the top cover 22 can move from the first position to the second position when the operating member 24b is operated. The locking member 24c has an engaging portion 24c1 and shaft portions 24c2, 24c2.

[0027] The inside of the engaging portion 24c1 has a shape (substantially U-shaped in this embodiment) that corresponds to the wall portion 224. The engaging portion 24c1 surrounds the wall portion 224 in the locked position.

[0028] The shafts 24c2, 24c2 are inserted into the hole 24a3, and are thereby journaled by the hole 24a3, thereby allowing the engaging portion 24c1 to rotate (swing) around the shafts 24c2, 24c2 as a central axis.

[0029] 3 around the shafts 24c2, 24c2 as the central axis, the user presses the pressing portion 24b3 with his / her finger, thereby disengaging the hook portion 24b1 from the hook receiving portion 223. This releases the lock of the top cover 22. Based on the above, an example of how to use the beverage container 10 will be described. A user pours a beverage into the container body 1. Thereafter, the drinking spout part 23 is attached to the lid body 21. FIG. 6 is a diagram illustrating the operation of attaching the drinking spout part to the lid body.

[0030] When attaching the spout part 23, the user grasps the spout part 23 and brings the abutting portion 23c into contact with the support portion 210a. The user then rotates the spout part 23 counterclockwise, using the abutting portion between the abutting portion 23c and the support portion 210a as a fulcrum. This causes the rear supported portion 23d to come into contact with the underside of the support portion 210b. If the user continues to apply force, the rear supported portion 23d will climb over the support portion 210b and be positioned above the support portion 210b. This means that the rear supported portion 23d is supported by the support portion 210b. Furthermore, as shown in FIG. 5, the engaging portion 23b comes into contact with the engaged portion 213. Thus, when attaching the spout part 23 to the lid body 21, the engaging portion 23b does not serve as a fulcrum for rotation.

[0031] Then, the user rotates the top cover 22 in the axial direction of the shaft 212 to move the hook receiving portion 223 in a direction approaching the hook portion 24b1. This causes the hook receiving portion 223 to push the sloped upper surface of the hook portion 24b1 outward. After climbing over the hook receiving portion 223, the hook portion 24b1 moves inward due to the bias of the coil spring and engages with the hook receiving portion 223, locking the top cover 22 so that it cannot be opened (first lock). Then, the user rotates the engaging portion 24c1 clockwise to move it to the locked position (second lock). This prevents the top cover 22 from opening even if the user operates the pressing portion 24b3. Then, the user attaches the cover 2 to the container body 1. To open the top cover 22, the user performs the reverse of the above-described operations. That is, the user flips the engaging portion 24c1 downward to release the second lock.

[0032] Next, the user presses pressing portion 24b3, thereby disengaging hook portion 24b1 from hook receiving portion 223. This releases the lock (first lock) of top lid 22. By releasing this first lock, top lid 22 can be placed in an open state as shown in Figure 2. The user can drink the beverage in container body 1 by placing their mouth on drinking spout 23a and tilting beverage container 1.

[0033] As described above, the beverage container 10 of the embodiment includes a container body 1, a lid body 21 having an opening 210 and attached to the container body 1, a drinking spout part 23 that is detachably attached to the lid body 21 and positioned within the opening 210 when attached, and a lid part 2 having a top cover 22 that is rotatably attached to the lid body 21 and can be positioned between a first position that covers the drinking spout part 23 and a second position that can be rotated to allow beverage to flow through the drinking spout part 23. The drinking spout part 23 has an engaging part 23b that can engage with the lid body 21 when the drinking spout part 23 is attached to the lid body 21, and the lid body 21 has an engaged part 213 that is located away from the opening edge of the opening 210 and separated by a step, with which the top of the engaging part 23b engages. By providing the engaged part 213 separated by a step, the area over which the engaging part 23b engages with the engaged part 213 is smaller than when no step is provided. This allows the drinking spout part 23 to be attached and detached with less force. In addition, the engaging portion (the contact portion between the contact portion 23c and the support portion 210a) is less likely to break. Furthermore, even if the portion 213a of the engaging portion 23b that is connected to the engaged portion 213 is small, the strength of the engaged portion 213 as a component can be ensured by providing a large portion 213b.

[0034] Furthermore, in the first position, the peripheral surface of the drinking spout part 23 (the surface between the engagement part 23b and the abutment part 23c) does not abut the inner surface of the support part 210a, and there is space near the rotation axis, so when attaching or removing the lid, the parts do not interfere with each other and can be rotated with little force.

[0035] 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. [Explanation of symbols]
