Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a ceramic cup excellent in cushioning property, stability and design.

[0002]

2. Description of the Related Art Conventionally, ceramic cups have been compared with glass or plastic cups, for example, because they are heavier, have better texture and feel, and have higher texture and decorativeness. Rarely used.

[0003] However, since this kind of pottery cup is made by sintering the earth, 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 the stability when placed is poor, and furthermore, the table or tray on which the ceramic cup is placed is damaged. There is fear.

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. There were disadvantages.

[0005]

DISCLOSURE OF THE INVENTION The present invention has been proposed in the above situation, and has been proposed to provide a novel ceramic cup having an extremely simple structure and process, and having excellent cushioning, stability and design. It seeks to provide structure.

[0006]

That is, the present invention provides:
Forming a circular bottom peripheral surface portion on the outer peripheral portion near the bottom of the ceramic cup body through a step lower than the outer peripheral surface of the cup body,
A ceramic cup wherein a ring packing made of an elastic body having a thickness protruding from the bottom of the cup body and an inner peripheral surface having a diameter smaller than the diameter of the circular bottom periphery is press-fitted to the circular bottom peripheral surface. According to.

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

[0008] 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.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below 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. 2, and FIG. It is a perspective view showing the glass group of a glass cup.

The pottery cup 10 of the present invention is used as a so-called mug cup or coffee cup, or as a free cup or cup, and is not particularly limited to the shape and the handle having the handle 18 as in the embodiment.

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 which is press-fitted near 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. Therefore, as shown in FIG.
The lower side is an open L-shaped circular groove having an inverted cross section.

The ring packing 20 comprises an inner peripheral surface 21 having a diameter x smaller than the diameter a of the circular bottom peripheral surface portion 15 and an elastic body having a rectangular section having a thickness y projecting from the bottom portion 12 of the cup body 11. Become. In the embodiment, the diameter b of the inner peripheral surface 21 of the ring packing 20 is 70 mm with respect to the diameter a of the circular bottom peripheral surface portion 15, and the height b of the step portion 16 from the floor surface 12 of the circular bottom peripheral surface portion 15. 7 mm, the thickness y of the ring packing is 7.5 to 8 m
m.

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 of the ring packing 20 generated in the radially expanding direction. Moreover, even if the circular bottom peripheral surface portion 15 has some molding errors, it can be easily attached.
Incidentally, the inner periphery of the ring packing 20 and the circular bottom peripheral surface 1
The difference from the outer circumference of 5 can be attached without a problem up to about 5 mm in diameter. That is, the cup body 11
The ring packing 20 is bonded to the ring packing 20 only by the elastic force of the ring packing 20 without using any adhesive or the like.

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 placed on a table or the like in a state where the ring packing 20 is pressed into the cup body 11. When it is 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 is
It has appropriate elasticity and flexibility, has heat resistance of 200 to 250 ° C. and cold resistance of −50 to −70 ° C., and has many advantages such as excellent corrosion resistance and little deterioration even in long-term use.

Further, 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. 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.

Further, by providing the ring packing 20 with a color, the mounted ring packing 20 has a decorative effect of the cup 10 and improves the appearance.

Further, as described above, the ring packing 20 is used.
In the case where the color is given, as shown in FIG.
The ceramic cup 10 can have variations as a plurality of types of cup groups 10A, 10B, 10C, 10D, in which the color of the ring packing 20 is different. Moreover, the cup groups 10A, 10B, 10
C, 10D, are ring packings 20A, 20B, 2 having different colors with respect to the same kind of ceramic cup body 11.
By mounting 0C, 20D, etc., various types of series products can be easily and easily constructed.

[0020]

As shown and described above, according to the present invention, a novel ceramic cup having excellent cushioning, stability and design can be obtained with a very simple structure and process.

Further, according to the second aspect of the present invention, 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 a sense of unity as a ceramic cup. 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 further 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. Only with this, it is possible to easily form a cup group with a variety of color variations.
