Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a simple cup made of synthetic resin for storing hot beverages and the like.

“Prior Art” In order to give a heat insulating effect to a resin cup, it has been common to have a double wall structure in the past.

"Problems to be solved by the invention" However, conventionally, there was a problem that the cost was increased due to an increase in material cost because the entire peripheral wall was a double wall. In addition, since the outer peripheral wall is conventionally formed by a simple flat surface, the rigidity of the outer peripheral wall is low, so that the outer wall is dented when held by hand and the heat insulating effect is reduced and the user feels uneasy. There was a point.

Therefore, an object of the present invention is to provide a simple cup having a high reliability by externally fitting a cover cylinder having a corrugated cross section on the upper half of the peripheral wall of the cup body.

[Means for Solving Problems] In order to solve the above-mentioned problems, the simple cup of the present invention raises the peripheral wall 4 from the peripheral edge of the bottom wall 3 and surrounds the peripheral groove 4 with the engaging groove 5 in the vertical center. And a cup body 1 made of synthetic resin, in which the locking projections 8 and 9 are provided around the upper end of the peripheral wall.
And the lower edge is fitted and locked in the engaging groove 5,
The cover body 2 is made of a synthetic resin and has a corrugated cross section in which the upper end edge is abutted and locked to the lower surface of the locking projection to be externally fitted.

[Operation] For example, as shown in FIG. 1, the cup body 1 can be held by hand through the cover tube 2.

Since the cover cylinder is formed in a corrugated cross section, an air layer B is formed between the cup body peripheral wall 4 and the cup main body peripheral wall 4, and the rigidity of the cover cylinder itself is increased.

[Embodiment] An embodiment of the cup of the present invention will be described below with reference to the accompanying drawings.

In FIG. 1, 1 is a cup body and 2 is a cover cylinder, both of which are molded and manufactured in a cylindrical shape using a synthetic resin material.

The cup body 1 has a peripheral wall 4 rising from the peripheral edge of the bottom wall 3 in the shape of a taper cylinder having a large diameter upward. An engaging groove 5 is circumferentially provided on the outer surface of the intermediate portion of the peripheral wall 4, and the upper end of the peripheral wall 4 is curled.

The cover cylinder 2 has a cylindrical wall 6 formed in a corrugated cross section, and an inward flange 7 is attached to the lower end of the cylindrical wall 6, and the upper end of the cylinder wall 6 is provided in the curling portion 8 as a locking ridge. Moreover, the inner peripheral end portions of the inward flanges 7 are fitted into the engaging grooves 5, respectively, and are fitted onto the upper half portion of the cup body peripheral wall 4.

2 and 3 show another embodiment of the cup of the present invention.

FIG. 2 shows that the cup body 1 is provided with an outward flange 9 as a locking projection on the upper end of the peripheral wall 4 and an outward flange 10 is attached to the upper end of the cover tube 2 cylinder wall 6 to cover them. This is an example in which the cylinders are simply butted in a fitted state.

FIG. 3 shows the cup body 1 and the cover tube 2 in FIG.
This is an example in which is formed into a rectangular tube shape.

[Advantages of the Invention] As described above, the simple cup of the present invention has the lower end edge fitted and locked in the engaging groove formed in the central portion in the vertical direction of the cup main body peripheral wall, and the upper end edge is surrounded by the upper end edge of the cup main body peripheral wall. Since the cover cylinder is fitted over the cup body by abutting the bottom surface of the locking ridge provided, liquid does not enter the gap between the cover cylinder and the cup body, resulting in better heat insulation. It can be done. In addition, the size of the cover cylinder can be suppressed to a necessary minimum, and the cost can be reduced by reducing the material cost.

Furthermore, because the cover cylinder is formed in a corrugated cross-section to increase rigidity, the cover cylinder does not dent when held by hand unlike the conventional example, and from this point also the good heat insulation effect is maintained. In addition to being able to do so, there is an advantage that it gives the user a sense of security.
