[Figure 9] FIG. 1 is a perspective view showing a drinking cup according to another embodiment of the present invention; DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0019] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. The beverage cup 1 of the first embodiment consists of a mug that can hold beverages such as coffee or soup and can be consumed by a consumer, and as shown in Figures 1 to 5, is configured to have a bottomed, cylindrical shape with an open top and a metal container portion 2 that can hold a predetermined volume of beverage, a separate portion 3 that is separate from the container portion 2 and can be attached and detached to the container portion 2, a locking member 4 as a retaining means, and a sealing member 5.

[0020] The container 2 according to this embodiment is formed by deep drawing a metal material such as stainless steel, has an opening edge 2a and a bottom surface 2b, and defines an internal storage space S, which can store a desired beverage such as coffee in the storage space S. When used in outdoor activities, the container 2 is configured so that the beverage in the storage space S can be heated by placing the bottom of the container 2 against a campfire or charcoal fire.

[0021] The separate part 3 is made of a material with a lower thermal conductivity than the container part 2, and is integrally formed with a mouth part 3a that covers the opening edge 2a of the container part 2 and a handle part 3b that the drinker can hold with his / her hand. Here, the separate part 3 according to this embodiment is made of wood, for example, obtained by cutting hardwood, and the mouth part 3a and the handle part 3b are continuously and integrally formed.

[0022] 5, the mouth 3a has an annular peripheral portion 3aa that follows the opening edge 2a of the container part 2, and by fitting the annular peripheral portion 3aa to the opening edge 2a of the container part 2 and locking it with a locking member 4, the mouth 3a of the separate part 3 and the opening edge 2a of the container part 2 become continuous. The handle part 3b is bent as desired so that it is easy for a drinker to grip with his or her hand, and is made up of a part that extends integrally from the mouth 3a toward the side.

[0023] The separate part 3 is not limited to wood cut from hardwood, but may be wood cut from softwood, for example, but hardwood has a higher cell density and fewer air holes than softwood, making it a harder material and more durable for long-term use. However, the separate part 3 is not limited to wood, and may be made of other materials such as hard resin, as long as the material has a lower thermal conductivity than the container part 2.

[0024] The locking member 4 as the retaining means in this embodiment engages and locks the separate part 3 and the container part 2, and is configured with a plurality of engaging fittings 4a attached to the outer circumferential surface of the drinking spout part 3a of the separate part 3, and a plurality of engaging fittings 4b and a locking fitting 4c attached to the outer circumferential surface of the container part 2. The locking fitting 4c is rotatable about the shaft part L, and can maintain the engaged state by rotating with the engaging fitting 4b engaged with the engaging fitting 4a.

[0025] When attaching the separate part 3 to the container part 2, the spout part 3a is placed on the opening edge 2a of the container part 2 so that the positions of the locking metal fittings 4a and the locking metal fittings 4b match, and after each locking metal fitting 4b is locked to the locking metal fittings 4a, the locking metal fitting 4c is rotated around the axis part L to lock it. This makes it possible to lock the attachment state of the separate part 3 to the container part 2, and when a drinker grasps the handle part 3b and lifts it up, the container part 2 follows the separate part 3 and can be lifted up, and the drinker can place their mouth on the spout part 3a to drink a beverage.

[0026] On the other hand, when removing the separate part 3 from the container part 2, each locking metal fitting 4c is rotated in the opposite direction to when it was locked to release the lock, and then the locking metal fitting 4b is released from the locked metal fitting 4a. This allows the attachment state of the separate part 3 to the container part 2 to be unlocked, so that when the separate part 3 is lifted up, it can be separated from the container part 2, and each can be washed and stored.

[0027] The sealing member 5 is made of a sealing material attached between the separate part 3 and the container part 2, and as shown in Fig. 5, is assembled between the annular peripheral edge 3aa of the drinking spout part 3a and the opening edge 2a of the container part 2, thereby enabling a seal between the container part 2 and the separate part 3. When the sealing member 5 is assembled to the container part 2 together with the separate part 3 and locked by the locking member 4, the locking force acts to firmly attach the sealing member 5 between the separate part 3 and the container part 2.

[0028] Next, a second embodiment of the present invention will be described. The beverage cup 1 according to the second embodiment, like the first embodiment, is a mug that can hold beverages such as coffee or soup and can be consumed by a drinker, and as shown in Figures 6 to 8, is configured with a metallic container part 2 that is tubular with a bottom and an open top and can hold a predetermined volume of beverage, a separate part 3 that is separate from the container part 2 and can be attached to and detached from the container part 2, and a screw part 6 as a holding means. Note that the same parts as those in the first embodiment are given the same reference numerals, and detailed explanations thereof will be omitted.

[0029] The thread shape 6 as a retaining means maintains the attachment state of the separate part 3 to the container part 2, and as shown in Fig. 7, is composed of a male thread shape 6a formed on the outer peripheral surface of the opening edge 2a of the container part 2, and a female thread shape 6b formed on the inner peripheral surface of the drinking spout part 3a of the separate part 3. That is, by matching the male thread shape 6a and the female thread shape 6b and rotating the container part 2 and the separate part 3 relative to each other, the male thread shape 6a can be screwed into the female thread shape 6b and locked.

[0030] Specifically, when attaching the separate part 3 to the container part 2, the male thread shape 6a of the container part 2 is matched with the female thread shape 6b of the separate part 3, and then the container part 2 and the separate part 3 are rotated relative to each other about their respective axes, whereby the male thread shape 6a and the female thread shape 6b screw together, thereby maintaining the attachment state of the separate part 3 to the container part 2. As a result, when a drinker grasps the handle part 3b and lifts it up, the container part 2 can be lifted following the separate part 3, and the drinker can drink a beverage by placing his / her mouth on the drinking spout part 3a.

[0031] On the other hand, when removing the separate part 3 from the container part 2, the container part 2 and the separate part 3 are rotated about their respective axes in the opposite direction to that at the time of attachment, thereby releasing the screw engagement between the male thread shape 6a and the female thread shape 6b. This allows the attachment state of the separate part 3 to the container part 2 to be released, and therefore, by lifting up the separate part 3, the separate part 3 can be separated from the container part 2, and each can be washed and stored.

[0032] When the separate part 3 is attached to the container part 2, a seal member 5 (see FIG. 7) similar to that of the first embodiment is interposed between the container part 2 and the separate part 3, making it possible to seal between the container part 2 and the separate part 3. When removing the separate part 3 from the container part 2, the seal member 5 can be separated in addition to the separate part 3 and the container part 2, so that each can be thoroughly washed and stored.

[0033] According to the first and second embodiments described above, the device comprises a metallic container portion 2 having a bottomed cylindrical shape with an open top and capable of holding a predetermined volume of beverage, and a separate portion 3 made of a material having a lower thermal conductivity than the container portion 2 and integrally formed with a drinking spout portion 3a that covers the opening edge 2a of the container portion 2 and a handle portion 3b that can be held by the drinker's hand. Therefore, burns to the drinker's mouth and hands can be avoided when drinking the beverage contained in the metallic container portion 2.

[0034] In particular, since the separate part 3 according to the first and second embodiments is made of wood, a beverage cup with low thermal conductivity and high designability can be provided. That is, by making the separate part 3 out of wood, it is possible to reliably suppress the thermal conduction from the container part 2, and to improve the designability by utilizing the annual rings and patterns inherent to wood. Furthermore, by using wood made of hardwood, it is possible to make the cup hard and durable for long-term use.

[0035] Furthermore, the separate part 3 in the first and second embodiments is detachable from the container part 2 and is provided with holding means (4, 6) for maintaining the attachment state of the separate part 3 to the container part 2. Therefore, the separate part 3 can be removed from the container part 2 and thoroughly and effectively washed, thereby improving hygiene.

[0036] Of these, the holding means according to the first embodiment is composed of a locking member 4 that engages and locks the separate part 3 and the container part 2, so that the separate part 3 can be stably and reliably attached to the container part 2 and the attached state can be maintained. Also, the holding means 6 according to the second embodiment is composed of a screw shape (male screw shape 6a and female screw shape 6b) that screws together the separate part 3 and the container part 2, so that the separate part can be attached to the container part with a simple screw shape.

[0037] Furthermore, according to the first and second embodiments, since there is a sealing member 5 that seals between the separate part 3 and the container part 2, it is possible to reliably seal between the opening edge 2a of the container part 2 and the separate part 3, and when removing the separate part 3 from the container part 2, the sealing member 5 can be removed, allowing the container part 2, separate part 3 and sealing member 5 to be thoroughly washed.

[0038] Although this embodiment has been described above, the present invention is not limited to this, and for example, as shown in Fig. 9, the separate part 3 may be fixed to the container part 2 with an adhesive or the like in a state where it is attached thereto, and the handle part 3b may have various different shapes in consideration of design. Furthermore, the container part 2 may be made of various other metals in addition to being made of stainless steel as in this embodiment. [Industrial Applicability]

[0039] The present invention can also be applied to devices with different external shapes or devices with added functions, etc., so long as they have the same gist as the present invention. [Explanation of symbols]
