Description

[Detailed Description of the Invention] <Industrial Field of Application> This invention relates to a cooling device for storing, for example, a large number of relatively small capacity containers and keeping them cool.

<Conventional technology> As is well known, when lactic acid bacteria drinks, milk, soft drinks, etc. are sold at workplaces or delivered, they are stored in a box-shaped cooler and kept at a low temperature using the cold insulation material inside the cooler. I am selling it while doing so.

The conventional cold storage device described above is a box frame made of a heat insulating material, and ice, other cold storage materials, and a beverage container are stored therein to cool the beverage container.

<Problem that the invention aims to solve> Therefore, in conventional cold storage devices, as the ice melts over time, the container becomes submerged in water, and water gets inside the container and dilutes the beverage inside. In some cases, water may be mixed into beverages and the commercial value may be lost.

Further, the temperature distribution inside the box frame is uneven, and among the many containers stored inside the device, there are cases where the containers are not cooled depending on their position in the device. In particular, when using a cold insulating material such as dry ice or cold storage material, the container may be cooled too much, or only the container that is in contact with the cold insulating material will be cooled and other containers will not be cooled.

Furthermore, because it is made of synthetic resin, when ice packs are added, the temperature change causes the ice pack to deform significantly, particularly near the opening at the top, and the airtightness is lost.

Furthermore, since the upper lid is made of thin synthetic resin, it sag and deform due to its own weight, which also causes gaps to occur.

<Means for Solving the Problems> The present invention was devised to solve the above-mentioned problems, and consists of storing a cold insulating material inside the entire circumference of the upper end of an insulating box frame whose top surface is open. This cold storage device is constructed by assembling a holder having fin members on its lower surface, and further providing an insulating lid frame that can be opened and closed from the upper end of the box frame to the upper surface of the holder.

<Example> The present invention will be explained below based on the drawings of the example.

In general, the cold storage device 1 of the present invention includes a box frame body 2 made of a heat insulating material, whose top surface is open, and a
This is a configuration in which a holder 3 is assembled.

The above-mentioned box frame 2 is, for example, as shown in FIG. 4, a box frame 4 with an open top whose four sides and bottom are integrally molded from a heat insulating board made of polystyrene foam or other material, and whose inner and outer surfaces are made of synthetic resin. A sheet material 5 made of

On the other hand, in the first embodiment shown in FIGS. 1 to 4, the holder 3 is made by cutting a groove-shaped long material made of extruded aluminum into appropriate dimensions, and attaching the box frame 2 to the holder 3.
It has a square ring shape so as to fit inside the upper end of the ring.

The holder 3 has an inner wall 7 erected on the inner edge of the bottom wall 6, and an outer wall 8 erected on the outer edge of the bottom wall 6. A large number of fin members 9 are provided along the outer wall 8, and a collar piece 10 is provided at the upper end of the outer wall 8, which is bent outward at a right angle.

Therefore, this collar piece 10 is mounted on the upper ends of the four sides of the box frame body 2, and the holder 3 is fitted into the upper end of the box frame body 2, and the bottom wall 6, inner wall 7, and outer wall 8 are connected to each other. A cold insulating material A such as dry ice or cold storage material is stored in the space formed by.

Next, from the upper end of the box frame 2 to the upper surface of the holder 3, a lid frame 11 made of a quadrilateral plate-shaped heat insulating material is attached so as to be openable and closable, and from the upper surface to the outer surface, a sheet made of synthetic resin is attached. With the material 12 pasted and the opening 13 formed in the center of the top surface opened and closed,
A thin synthetic resin lid piece 14 is attached using, for example, a hook-and-loop fastener.

In the above structure, the inside of the box frame 2 is almost airtightly closed by the lid frame 11 and the lid piece 14, and the holder 3 is fitted into the upper end of the box frame 2. Therefore, the deformation of the box frame body 2 is prevented, and even though the lid piece 14 is made of thin synthetic resin, it is supported by the lid frame body 11, so that it does not sag and deform under its own weight and form a gap. Moreover, since the upper surface of the holder 3 is covered by the lid frame 11 made of a heat insulating material, the cold air of the cold insulating material A inside the holder 3 is not released to the outside.

In the airtightly closed box frame 2 described above, the cold air of the cold insulation material A is transferred to a large number of fin members 9.
A large number of containers can be effectively and uniformly cooled and kept cool.

The embodiments shown in FIGS. 5 to 8 show a second embodiment of the present invention.

The holder 3 in this embodiment is constructed by combining four cartridge bodies 15 into a rectangular shape. This cartridge body 15 has a trapezoidal planar shape, the oblique sides of the left and right edges are inclined at an angle of approximately 45 degrees, and side walls 17 are erected on both sides and both ends of a flat bottom wall 16. A lid plate 18 is disposed on the top surface of the bottom wall 16 so as to be slidable and openable, and a large number of fin members 9 described above are provided along the length direction on the bottom surface of the bottom wall 16, and a large number of partition plates 19 are provided on the top surface of the bottom wall 16. is provided along the length direction, and inside,
It stores cold insulation material A.

Further, these cartridge bodies 15 are assembled into the upper end portion of the box frame body 2 via four sets of support frames 20 attached to the four corners of the upper end of the box frame body 2.

The support frame 20 has an inner plate 22 on the inside of a bottom plate 21 and an outer plate 23 on the outer side.The inner plate 22 and the outer plate 23 are curved in an L shape along the vertical direction. Further, the upper end of the outer plate 23 is bent outward to form a flange 24. Therefore, this collar part 24
The support frame 20 can be assembled to the box frame body 2 by placing the support frame 20 on the top corner of the box frame body 2, and the ends of the adjacent cartridge bodies 15 can be mounted on the bottom plate 21.
By placing the cartridge body 15 on the cartridge body 15, the end portion of the cartridge body 15 is held by the inner plate 22 and the outer plate 23. By fitting the four cartridge bodies 15 into the support body 20 in this way and combining them into a square ring shape, the holding body 3 can be constructed and can be fitted into the upper end of the box frame body 2. .

Incidentally, in the above-mentioned second embodiment, the symbols not explained have the same structure as the symbols in the above-mentioned first embodiment, so the explanation will be omitted.

Although the present invention has been described above with reference to the embodiments shown in the drawings, the present invention is not limited to the above-described embodiments, and may be implemented in any manner as long as the configuration described in the claims for utility model registration is not changed. can.

<Effects of the invention> In short, according to the invention, since the inside of the box frame is airtightly closed by the lid frame and the lid piece, there is no risk of the cold air inside escaping to the outside. Therefore, it is possible to reliably achieve the cold insulation effect, and since the holder is fitted into the upper end of the box frame, deformation of the box frame 2 is prevented, and the lid piece is not attached to the lid frame. Since it is supported vertically, it will not sag and deform due to its own weight, and therefore no gaps will be formed, so the above-mentioned airtight state is further ensured.

Further, since the upper surface of the holder is covered with the lid frame made of a heat insulating material, the release of cold air to the outside is further prevented.

Inside the airtight box frame,
The cold air from the cold insulation material is supplied downward by a large number of fin members, and a large number of containers can be effectively cooled and kept cool for a long period of time without any corners while maintaining a constant temperature. The product value of the storage container will not be reduced by melted ice water, and the internal temperature can be adjusted depending on the amount and type of cold storage material, making it especially useful for selling lactic acid bacteria drinks, milk, soft drinks, etc. at workplaces. It is possible to provide products with high practical value when selling or delivering products.
