Description

[Detailed description of the invention] [Field of industrial application] The present invention allows the volumetric capacity of the enclosed cooling medium liquid to change on the concave spherical surface provided on the circumferential surface of the enclosed container, thereby reducing the volume of the enclosed cooling medium due to repeated use as a cooling device. The present invention relates to the disclosure of a cooling device structure that suppresses fatigue and wear and tear of the cooling device as much as possible, and effectively corrects inconveniences in use and loss of commercial value in terms of appearance.

[Conventional technology]

Previously, this type of cold storage device, cold preservation device, or cooling device had a container with a flat or spherical peripheral surface filled with a coolant liquid; However, in both cases, the container peripheral surface is constructed as a flat surface or a swollen spherical surface.

Therefore, when using a conventional cooling device for condensation, it was planned to leave a gap in the container corresponding to the condensation expansion of the sealed liquid and fill it with a cooling medium and seal it.

[The problem that the idea aims to solve]

However, in such a method, when the container is transparent or translucent, air bubbles inside the container can be seen from the outside, and especially when used as a substitute for ice, it can be easily identified as pseudo-ice. , which has seriously spoiled the appeal of its use.

In addition, in such a method, since the container is generally provided by blow molding a synthetic resin material, the air contained in the filled liquid may permeate and be forced out from the peripheral wall of the container during solidification. When the sealed liquid melts, a suction pressure corresponding to the internal pressure at the time of condensation is not generated, resulting in the circumferential surface of the container being depressed by an amount corresponding to the sealed air.

Therefore, upon subsequent use, depressions were formed at unspecified positions on the circumference of the container, severely damaging its appearance and making it obvious that it was actually plastic pseudo-ice. Moreover, when handling containers such as recondensation and washing, the contact resistance between the containers becomes large, which hinders smooth handling.

In addition, conventional cooling devices are constructed as a single piece,
It lacks its own engagement function and its appearance is particularly poor in decorative function.

[Purpose of the invention and means for solving the problem]

The re-cooling cooling device according to the present invention has been specially devised in view of the inconveniences in the conventional precedent. A recess corresponding to the amount of liquid is provided, and this recess is made to be able to expand outward to the position of the container peripheral wall surface, so that it can be used not only during condensation but also when the coolant liquid melts at room temperature. The main purpose is to prevent changes in the original appearance, and furthermore, the cooling device itself is provided with a diameter-reduced communication part to enable hanging use of the cooling device, and to prevent the diameter reduction from occurring. The purpose is to give the cooling device a unique external shape by having a communicating portion.

In order to achieve the above object, the present invention has a structure in which a container made of synthetic resin is constructed in which an enlarged container portion in the form of a spherical body with an enlarged diameter is connected to both sides via a diameter-reducing communication portion. A cooling medium liquid is sealed and sealed, and a concave spherical surface having a depth corresponding to the expansion capacity due to condensation of the cooling medium liquid is formed on the circumferential surface of the container at one or more locations. , which is placed at a point where the circumferential side surface is curved inward in an arc shape.

〔Example〕

A typical embodiment of the re-cool storage/cooling device according to the present invention will be described below with reference to the attached drawings. This is a synthetic resin material that has fewer problems, has less fatigue characteristics at low temperatures, and is less susceptible to aging phenomena due to repeated use, and is mass-produced by blow molding or rotary molding. .

Such a container a has enlarged container portions 2 and 3 in the form of a spherical or deformed spherical body integrally arranged on both sides of a diameter-reduced communication portion 1, and either or both of the connected container portions 2 and 3. A concave spherical surface 4 is recessed on one peripheral surface.

Although various shapes, especially diameter dimensions, of the container portions 2 and 3 are planned, one container portion is designed to have a larger diameter than the other, so-called a gourd shape. This is advantageous in terms of appearance, handling, and especially in suspension operations using the reduced diameter communicating portion 1.

When such concave spherical surfaces 4 are provided in a plurality of locations, the concave spherical surfaces 4 are provided with a slight gap between them so that the surfaces do not come into contact with each other.
The area between .

A suitable cooling medium liquid 5 is sealed in the container a having such a structure so as to prevent air from intervening as much as possible, and usually natural water is used as the cooling medium liquid 5. In particular, in cases where the objective is to increase the cooling function or cooling capacity, it is planned to use a cooling medium liquid with a low solidification temperature range below water and a large cold storage capacity.

[Results of the idea]

The cooling device according to the present invention has a characteristic structure as described above, in particular, concave spherical surfaces 4 to 4 corresponding to the increase in the condensation and expansion capacity of the cooling medium liquid 5 are recessed and arranged on the circumferential surface of the cooling device, and moreover, inside the container a. The specific effects of the above-mentioned characteristics are intended to be achieved by suppressing the generation of residual air as much as possible.

That is, even when the capacity of the container a increases or decreases due to a change in the form of the coolant liquid 5 sealed therein, the concave spherical surfaces 4 to 4 protrude and retract without any damage to the specific external shape of the container a, and the cooling medium can be increased or decreased. The volume expansion caused by the solidification of the liquid 5 is allowed.

Therefore, in the container a, concavity or bulge of the peripheral surface other than the concave spherical surface 4 is suppressed, and the concave spherical surfaces 4 to 4 are concave or bulge while the external appearance always maintains its initial shape. As a result, the appearance characteristics are particularly good, and the inconvenience of being able to identify at a glance that it is so-called pseudo ice made of plastic material is eliminated.

Moreover, due to this structure, mutual sliding of the containers a is made good, and cleaning, collection, coagulation, etc. by bulk handling can be performed with extremely low frictional resistance due to the so-called contact surface on the rounded surface. This is something that can be done in the future.

In particular, the cooling device according to the present invention avoids the expansion and contraction of the composition of the peripheral wall surface of the container a due to the expansion and contraction of the cooling medium liquid 5 due to the above-mentioned characteristic configuration, and prevents the composition from expanding and contracting due to repeated expansion and contraction of the composition. This is designed to suppress fatigue of the cooling device as much as possible, which increases the durability of the cooling device and also prevents staining due to minute cracks on the surface.

Therefore, these cooling devices are used not only as general cooling means such as cold storage, but also as various cooling means in distribution channels such as cooling means when selling and shipping fresh foods, etc., as well as as primary cooling means for fishing boats and other In addition to being used as a cooling means in various industries, it has a higher cooling capacity than general ice and does not generate melt water, so it is used in various service industries and even in daily life at home. It is planned that it will be used for a long time.

These cooling devices have a unique structure and shape that prevents them from rolling, and they can be suspended above the space above the cooling surface, so they are easier to handle than regular cooling devices. Improve the characteristics and cooling efficiency, and
Such shape characteristics also have the function of a general decoration, so when used as a cooling device when serving food that requires cooling, it can also have a decorative effect in addition to its cooling function. It is something that
