The present invention relates to a beverage container.
BACKGROUND ARTBeverage containers such as teacups and cups may be stacked and stored after being washed by a high temperature dishwasher after use, for example (e.g., Patent Literature 1).
CITATION LIST Patent Literature
- Patent Literature 1: Japanese Utility Model Registration No. 3114290
However, when a plurality of beverage containers are stacked, upper openings of the containers are closed, which brings inner spaces of the containers into a sealed state. For this reason, the smell of detergent may remain, and moisture vapor remaining in the inner spaces may appear as waterdrops once the moisture vapor has cooled. The present invention was made to solve the above problems, and an object of the present invention is to provide a beverage container capable of suppressing cases in which a smell remains or waterdrops attach to the containers even when stacked after being washed, for example.
Solution to ProblemA beverage container according to the present invention includes a bottom wall portion, and a side wall portion extending upward from a circumferential edge of the bottom wall portion, wherein, due to an outer diameter of the bottom wall portion being formed smaller than an outer diameter of the side wall portion, an annular stepped portion is formed at a lower end of the side wall portion, the step portion is provided with a plurality of recessed portions and a plurality of protruding portions that are alternately arranged in a circumferential direction, and a width of the stepped portion is larger than a width of an upper end of the side wall portion at at least portions where the recessed portions are formed.
In the above beverage container, the width of the stepped portion may be substantially the same as the width of the upper end of the side wall portion at portions where the protruding portions are formed.
In the above beverage container, a depression may be formed in a lower surface of the bottom wall portion, and grooves that bring an outer circumferential surface of the bottom wall portion into communication with the depression may be respectively formed at portions where the recessed portions are formed.
In the above beverage container, a configuration is also possible in which an annular elevation that downwardly extends from the lower surface of the bottom wall portion and has an outer diameter that is smaller than the outer diameter of the bottom wall portion.
In the above beverage container, a configuration is possible in which an annular elevation that downwardly extends from the lower surface of the bottom wall portion and has the outer diameter that is smaller than the diameter of the bottom wall portion, and gaps that are continuous with the grooves are formed at respective portions corresponding to the grooves.
In the above beverage container, the recessed portions and the protruding portions may be formed into a continuous wave shape in a side view.
Advantageous Effects of InventionAccording to the present invention, even when the beverage containers are stacked after being washed, cases in which a smell remains or waterdrops are attached can be suppressed.
Hereinafter, an embodiment in which a beverage container according to the present invention is applied to a beverage container will be described with reference to the drawings.
1. Structure of Teacup
As shown in
As shown in
Also, in the bottom wall portion 1, a groove 12 extending in the radial direction is formed at each portion corresponding to the recessed portions 211, and the depression 11 and an outer circumferential surface of the bottom wall portion 1 are in communication with each other via the grooves 12. The grooves 12 each have an arc-like shape in a side view, and as shown in
As shown in
2. Usage of Teacup
The teacups as described above are returned after use and washed by being sprayed with high-temperature wash water by a washing machine, or the like. Thereafter, a plurality of teacups are stacked and stored.
In order to stack the two teacups 10A and 10B, the upper end of the side wall portion of the first teacup 10A is brought into contact with the stepped portion 21 of the second teacup 10B.
Also, as shown in
Accordingly, as shown in
3. Features
As described above, according to the teacup according to the present embodiment, the following effects can be achieved.
(1) As shown in
(2) Since the recessed portions 211 and the protruding portions 212 of the stepped portion 21 are formed in a continuous wave shape in a side view, the design is improved. Also, as shown in
4. Variations
Although an embodiment of the present invention has been described above, the present invention is not limited to this, and various changes can be made without departing from the gist of the invention. Note that the following variations can be combined as appropriate.
(1) Although the elevation 3 is provided at the lower surface of the bottom wall portion 1 in the above embodiment, the elevation 3 is not necessarily needed, and the elevation can be omitted as shown in
(2) As shown in
(3) The number, depth, and width of the grooves 12 of the bottom wall portion 1 are not particularly limited, and it is sufficient that the outer circumferential surface of the bottom wall portion 1 is in communication with the depression 11.
(4) The recessed portions 211 and the protruding portions 212 of the stepped portion 21 need not have a wave shape in a side view, and the shape is not particularly limited. For example, as shown in
(5) In the above embodiment, an example is shown in which the beverage container of the present invention is applied to a teacup, but the beverage container may be used as a beverage glass, and the material of the container, the outer diameter, height, thickness of the side wall portion 2, the outer diameter, thickness of the bottom wall portion 1 and the like may be changed as appropriate. Also, the bottom wall portion 1 and the side wall portion 2 may have a shape other than a cylindrical shape, such as a polygonal shape.
