Description

[Detailed description of the invention] The present invention is designed so that the inside of the bag can be seen through from the outside, and the bag is filled with transparent or colored transparent water, a liquid such as antifreeze, or a high viscosity fluid, and the liquid or fluid is passed through the bag. This invention relates to a cold bag that allows the background, pattern, color, etc. of the inner wall to be seen through.

In general, this type of cold bag is one in which a cold storage material gel made by adding Poval, CMC, etc. to water is sealed in an opaque soft vinyl chloride bag or a translucent bag or container made of synthetic resin such as polyethylene or polypropylene. Various proposals have been made.

Colors, patterns, etc. are applied to the surfaces of the bags and containers as necessary.

The present invention was developed by focusing on the above-mentioned points, and is made by making a part of the bag made of synthetic resin, rubber, etc. transparent.
This bag is filled with a transparent or colored transparent liquid or a highly viscous fluid and sealed, and the inner wall of the bag is provided with a background, pattern, color, etc., so that the transparent or colored transparent liquid is filled through the transparent part of the bag. Or, it is possible to see through the high viscosity fluid and the background, pattern, color, etc. of the inner wall of the bag through this liquid or the high viscosity fluid, and therefore it is possible to see the background, pattern, etc. inside the bag three-dimensionally,
To provide a cooling bag that is aesthetically pleasing and can strongly arouse the interest of users, especially infants and children.

Another object of the present invention is to suspend a desired object in the transparent or colored transparent liquid or high viscosity fluid,
By matching this floating object to the background of the inner wall of the bag, for example, if the background is outer space, it can be used for artificial hygiene, a space station, etc.
By molding rockets, UFOs, etc., or tropical fish if they are underwater, the background inside the bag can be expressed more realistically and three-dimensionally, and floating objects can move due to external factors and appear as if flying in outer space. To provide a cold bag that looks like it is floating or swimming in seawater, further arousing the interest of infants and children.

Next, one embodiment of the present invention will be described based on the drawings.

FIG. 1 shows a cross-sectional view of a cold bag according to an embodiment of the present invention.
A perspective view is shown in FIG.

The packaging bag 1 uses a transparent synthetic resin sheet 2 having flexibility and watertightness on one side, for example, on the upper side, and an opaque sheet 3 of synthetic resin, rubber, etc., also having flexibility and watertightness on the lower side. It is sealed and molded.

A desired background, pattern, color, etc. 4 are applied to the inner wall of the opaque sheet 3.

The above background may be, for example, outer space, underwater, or a story (
This is a background picture for a fairy tale (fairy tale).

The packaging bag 1 is filled with a transparent or colored transparent cold storage material gel 5.

In this cold storage material gel 5, an arbitrary number of floating objects 6... corresponding to the background, pattern, color, etc. of the inner wall of the opaque sheet 3 are floated, and the floating objects 6...・・・
When the cool storage material gel 5 flows due to an external factor, it moves accordingly.

For example, if the background is outer space, the floating object 6 may be an artificial satellite,
For space stations, rockets, UFOs, etc., if they are underwater, they are molded into the shape of a tropical fish, and the necessary coloring is applied.

The floating matter 6 is formed of a material that can float in the cool storage gel 5.

The cold bag having the above structure is used after being cooled in a refrigerator-freezer or the like.

This cold bag has a transparent or colored transparent cold storage material gel 5 and floating matter 6 passed through the transparent sheet 2 on the top surface.
...and the background, pattern, color, etc. of the interior wall can be viewed and expressed three-dimensionally and realistically.

Further, the cool storage gel 5 flows due to external factors such as pushing the packaging bag 1, and therefore the floating objects 6 move together with the cool storage gel 5 and within the cool storage gel 5.

Therefore, for example, if the background is outer space and the floating objects 6 are artificial satellites, UFOs, etc., it will appear as if an artificial satellite, UFO, etc. are flying in outer space, and if the background is underwater and the floating objects 6 are If it is a tropical fish, it looks like the tropical fish is swimming in the sea.

In addition, in the cold storage bag of the present invention, antifreeze or the like is mixed as necessary in order to impart more fluidity to the cold storage material gel to be filled.

Furthermore, in the present invention, the transparent portion of the packaging bag 1 may be on one side, for example, not the entire top surface as in the above embodiment, but may be a part of the top surface.

FIG. 3 shows a sectional view of a cold bag according to a second embodiment of the present invention.

In this embodiment, the heat capacity of the cold bag is increased, and the bag is constructed so that the liquid or fluid containing the suspended matter does not lose its fluidity even when cooled.

The packaging bag 1 of this cold bag is formed into two layers with a partition wall 7 inside, and one side, for example, a transparent synthetic resin sheet 2 on the top side, and an opaque sheet of synthetic resin, rubber, etc. on the partition wall 7 and the bottom side. 3 is used.

A desired background, pattern, color, etc. are applied to the partition wall 7 facing the transparent synthetic resin sheet 2.

The layer A on the side of the transparent sheet 2 in the packaging bag 1 is filled with a liquid or fluid 5a that has a small heat capacity, such as a large amount of antifreeze mixed with the cold storage gel, or just antifreeze, and freezes even when cooled. It is designed to maintain liquidity without any problems.

This liquid or fluid 5a has a composition that is transparent or colored and transparent.

Further, a desired number of floating substances 6 are suspended in this liquid or fluid 5a.

On the other hand, the layer B on the side of the opaque sheet 3 is filled with a high viscosity fluid 5b such as only a cold storage gel having a large heat capacity or a cold storage gel mixed with a small amount of antifreeze.

FIG. 4 shows a sectional view of a cold bag according to a third embodiment of the present invention.

In this embodiment, the packaging bag is formed into two layers as in the second embodiment, and layer A on the side of the transparent sheet 2 is filled with a transparent or colored transparent liquid or fluid 5a having a small heat capacity to prevent suspended matter. is suspended, and the layer B on the side of the opaque sheet 3 is filled with a foamed elastic body 5C impregnated with a cold storage gel or the like having a large heat capacity.

In the present invention, the type and composition of the high viscosity fluid, such as a liquid or fluid with a small heat capacity, and a regenerator gel with a large heat capacity, is not limited at all.

As described above, the present invention includes forming a part of the bag transparent, filling the bag with transparent or colored transparent liquid, or high viscosity liquid, and providing a background, pattern, color, etc. on the inner wall of the bag. Therefore, the background, pattern, color, etc. of the inner wall of the bag can be seen through the transparent part of the bag, and the background, pattern, color, etc. of the inner wall of the bag can be seen through the transparent or colored transparent liquid or high viscosity fluid and this liquid or high viscosity fluid.
It has the advantage of being able to realistically represent patterns, etc. in three dimensions, having excellent aesthetics, and strongly arousing the interest of users, especially infants and children.
