Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a cooling container for making ice sweets such as sherbet, frozen pudding, and frozen jelly, and for keeping drinking water such as beer cold.

[Technical background of the invention and its problems]

Recently, cooling containers have been developed and put into practical use that can be used to easily make iced confections such as sherbet, frozen pudding, and frozen jelly at home, and to keep drinking water such as beer cold.

This type of cooling container has a double-walled container body filled with a cold pack, and FIG. 3 shows a conventional general configuration thereof. That is, a is the outer wall,
b is an inner wall body, each of which is integrally molded from synthetic resin. On the inner periphery of the upper edge of the outer wall body a, a convex strip c having a continuous arc-shaped cross section is formed along the circumferential direction. In addition, an inverted U is attached to the upper edge of the inner wall b.
A folded part d which is folded back in a character shape is formed, and a concave groove e corresponding to the above-mentioned convex strip c is formed on the outer periphery of the periphery of this folded part d.
is formed. Then, a fluid refrigerant f is accommodated inside the outer wall body a, and in this state, the outer wall body a
Insert the inner wall b into the inner wall, push the periphery of the inner wall b elastically into the inner periphery of the upper end of the outer wall a, and fit the groove e into the protrusion c to connect the outer wall a and the inner wall b. It is integrated. Then, this cooling container is placed in the freezer compartment of the refrigerator for a predetermined period of time, and after freezing the ice pack f, it is taken out, and syrup is poured into the cooling container and stirred to make a sherbet, or beer or the like is placed in the cooling container. Put it in and keep it cold.

However, in the past, since the folded portion d has an inverted U-shaped cross section, the periphery of the opening of the cooling container becomes thick, which makes it particularly difficult to store drinking water such as beer in the cooling container. The problem was that it became difficult to drink.

[Purpose of invention]

The present invention was developed with attention to these points, and its purpose is to provide a cooling container that makes drinking water such as beer easier to drink when it is stored therein. be.

[Summary of the idea]

That is, the present invention has a hollow container body with a double wall structure, and the hollow space is filled with a refrigerant, and the cross section of the upper end of the container body is formed into an inverted V-shape. The opening is widened into a flap shape, and reinforcing ribs are provided inside the inverted V-shaped cross section.

[Example of idea]

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. In the figure, 1 is the outer wall body, 2
is an inner wall body, each of which is integrally molded from a synthetic resin with excellent low temperature resistance. Outer wall 1
A convex strip 3 having a continuous arcuate cross section along the circumferential direction is formed on the inner periphery of the upper end edge. In addition, a folded part 4 which is folded in an inverted V shape is provided at the upper edge of the inner wall body 2.
is formed. Since the folded portion 4 has an inverted V-shape, the opening 5 of the inner wall 2 widens in a tapered shape, and its peripheral edge is thin and sharp. Reinforcing ribs 6 are integrally formed inside the folded portion 4 at regular intervals along its circumferential direction. Moreover, a groove 7 corresponding to the above-mentioned protrusion 3 is formed on the outer periphery of the periphery of the folded portion 4. Furthermore, a ventilation hole 8 is formed in the upper edge of the outer wall 1 at a certain distance from the edge, that is, located below the protrusion 3.

Thus, the cold pack 9 is accommodated inside the outer wall 1, and in this state, the inner wall 2 is inserted inside the outer wall 1, and the inner periphery of the folded part 4 of the inner wall 2 is placed on the outer periphery of the upper end of the outer wall 1. is pushed in elastically, the concave groove 7 fits into the convex strip 3, and just before this fitting, the ventilation hole 8 is sealed by the tip of the folded part 4, and thereby the outer wall body 1 and the inner wall body 2 are combined, and a hollow part 1 between them
An integral container body 11 in which a cold pack 9 is filled
is configured. Note that 12 is a handle that is integrally provided on the side surface of the container body 11. Also,
As the cold pack 9, for example, water is added to an organic thickener such as wheat starch to prepare a paste, and 5 to 16% by weight of salt mainly composed of sodium chloride is added to the paste.
The viscosity is adjusted to 2 to 3000 poise by adding it. Such a cold pack 9 maintains a paste state even when cooled to about -20°C, and expands little as the temperature drops, so that the outer wall 1 and inner wall 2 may be inadvertently deformed or damaged. It is advantageous in that there is nothing to do.

According to such a cooling container, when drinking water such as beer stored in the container main body 11, the opening 5 expands in a shape of a tsuppa and its peripheral edge becomes thin. , the drinking water becomes easier to drink. Furthermore, if the cross-section of the peripheral edge of the opening 5 becomes an inverted V-shape, the V-shape is likely to be deformed, but reinforcing ribs 6 are provided inside the cross-section; It is possible to reliably prevent deformation and improve durability.

Note that this invention is not limited to the structure of the above embodiment; for example, the folded portion of the above embodiment may be extended to the bottom of the inner wall, and a lid-shaped wall may be fitted into the opening. There is no problem even if it is structured as follows.

[Effect of idea]

As explained above, according to the present invention, the cross section of the upper end of the container main body is formed into an inverted V shape, the opening at the upper end is widened in a flat shape, and reinforcing ribs are provided inside the cross section. As a result, the peripheral edge of the opening becomes thinner, making it easier to drink drinking water such as beer stored in the container body, and the strength of the peripheral edge of the opening is increased to prevent deformation. This has the effect of improving durability.
