Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 This invention relates to the structure of a ceramic cup with excellent cushioning and stability and design.

[0002]

[Prior art]

 Traditionally, ceramic cups have been favored and used because they are heavier, have better texture and touch, and have a higher texture and decoration than glass or plastic cups, for example. I have.

[0003] However, since this kind of pottery cup is made by sintering the soil, a feeling of unevenness or roughness remains on the bottom surface. In such a ceramic cup, there is a problem that the bottom portion is slippery, and a sense of stability when placed is poor, and furthermore, the table or tray on which the ceramic cup is placed may be damaged. There is a risk that it will.

In order to solve this problem, it has recently been proposed to attach a cushioning material having a non-slip effect to the bottom of the ceramic cup, but this increases the cost of the manufacturing process, which is complicated. There were disadvantages.

[0005]

[Problems to be solved by the invention]

 This invention has been proposed in the above situation, and aims to provide a novel ceramic cup structure having excellent cushioning, stability and design with a very simple structure and process. .

[0006]

[Means for Solving the Problems]

 That is, in the present invention, a circular bottom peripheral surface is formed on the outer peripheral portion near the bottom of the ceramic cup body via a step portion lower than the outer peripheral surface of the cup body, and the circular bottom peripheral surface is formed on the circular bottom peripheral portion. And a ring packing made of an elastic body having a thickness protruding from the bottom of the cup body and having a diameter smaller than the diameter of the cup body.

The invention of claim 2 relates to the ceramic cup according to claim 1, wherein the ring packing is fitted almost flush with the outer peripheral surface of the ring packing and the outer peripheral surface of the cup body.

The invention of claim 3 relates to the ceramic cup according to claim 1 or 2, wherein the ring packing has a color.

The invention according to claim 4 relates to the ceramic cup according to claim 3, wherein the cup constitutes a plurality of types of cup groups having different colors of ring packing.

[0010]

[Embodiment of the invention]

 Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is an exploded perspective view of a ceramic cup body and a ring packing showing one embodiment of the present invention, FIG. 2 is an overall perspective view of the same assembled state, FIG. 3 is a central longitudinal sectional view of FIG. It is a perspective view showing the glass group of a ceramics glass.

The ceramic cup of the present invention is used as a so-called mug or coffee cup or a free cup or a cup, and is not particularly limited to those having the shape as in the embodiment and those having the handle portion 18. Absent.

As shown in FIGS. 1, 2 and 3, the ceramic cup 10 of the present invention comprises a cup body 11 and a ring packing 20 press-fitted in the vicinity of the bottom 12 thereof. The circular bottom peripheral surface portion 15 of the cup body 11 is formed on an outer peripheral portion near the bottom portion 12 of the cup body 11 via a step 16 lower than the outer peripheral surface of the cup body 11. Accordingly, as shown in FIG. 3, the circular bottom peripheral surface portion 15 is a circular groove having an inverted L-shaped cross section with a lower open section.

The ring packing 20 has an inner peripheral surface 21 having a diameter x smaller than the diameter a of the circular bottom peripheral surface portion 15, and a cross-sectional rectangular elastic body having a thickness y protruding from the bottom portion 12 of the cup body 11. Consisting of In the embodiment, the diameter a of the circular bottom peripheral surface portion 15 is 72 mm, the diameter of the inner peripheral surface 21 of the ring packing 20 is x70 mm, and the height b of the step portion 16 from the floor surface 12 of the circular bottom peripheral surface portion 15. Is 7 mm, whereas the thickness y of the ring packing is 7.5 to 8 mm.

Since the ring packing 20 has the inner peripheral surface 21 having a diameter smaller than the diameter of the circular bottom peripheral surface portion 15 as described above, when the ring packing 20 is attached to the step portion 16 of the circular bottom peripheral surface portion 15, When the ring packing 20 is stretched and fitted, the inner peripheral surface 21 is pressed against the circular bottom peripheral surface 15 due to the elasticity generated in the radially expanding direction of the ring packing 20 so as to come into close contact therewith. In addition, even if there is some molding error in the circular bottom peripheral surface portion 15, it can be easily attached. Incidentally, the difference between the inner periphery of the ring packing 20 and the outer periphery of the circular bottom peripheral surface portion 15 can be attached without any problem up to a diameter of about 5 mm. That is, the cup main body 11 and the ring packing 20 are joined together only by the elastic force of the ring packing 20 without using any adhesive or the like.

Further, since the ring packing 20 has a thickness y protruding from the bottom 12 of the cup body 11 as described above, the ring packing 20 is pressed onto the table in a state where the ring packing 20 is pressed onto the cup body 11. When placed, the bottom portion 23 of the ring packing 20 reduces contact with the table.

The ring packing 20 is preferably made of silicone rubber. This silicone rubber has moderate elasticity and flexibility, heat resistance of 200 to 250 ° C and cold resistance of -50 to -70 ° C, excellent corrosion resistance and little deterioration over long-term use. Has the advantage of

It is preferable that the outer peripheral surface 22 of the ring packing 20 and the outer peripheral surface of the cup body 11 are mounted almost flush with each other, as defined in claim 2. By attaching the ring packing 20 in this way, the feeling of discomfort caused by attaching the ring packing 20 to the outer periphery of the cup body 11 is eliminated, and the unit has a sense of unity.

In addition, by providing the ring packing 20 with a color as defined in claim 3, the mounted ring packing 20 has a decorative effect of the cup 10 and improves appearance.

Further, in the case where the ring packing 20 is given a color as described above, as shown in FIG. 4, a plurality of types of cup groups 10A, 10B, 10C, 10D, in which the color of the ring packing 20 is different, are provided. In addition, the ceramic cup 10 can have variations. Moreover, the above-mentioned cup groups 10A, 10B, 10C, 10D, etc. can be diversified by attaching ring packings 20A, 20B, 20C, 20D, which are different in color, to the same kind of ceramic cup body 11. Series products can be configured easily and easily.

[0020]

[Effect of the invention]

 As shown and described above, according to the present invention, it is possible to obtain a new ceramic cup excellent in cushioning property, stability, and design with an extremely simple configuration and process.

Further, according to the invention of claim 2, since the ring packing is fitted flush with the outer peripheral surface of the cup body, there is no sense of incongruity in appearance, and the sense of unity as a ceramic cup is maintained. is there.

According to the third aspect of the present invention, since the ring packing has a color, a decorative effect is given to the ceramic cup, and the design is more improved.

Further, according to the invention of claim 4, since the cups constitute a plurality of types of cup groups having different colors of the ring packing, different types of ring packings are fitted to the same type of cup body. Just by wearing, you can easily form a cup group with a wide variety of colors.
