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.

<Prior art> As is well known, when lactic acid bacteria drinks, milk, soft drinks, etc. are sold at workplaces or delivered, the containers are stored in a box-shaped cold storage device, and the cold storage material inside the cold storage device is stored. It is sold while being kept at a low temperature.

The above-described conventional cold storage device is a box frame made of a heat insulating material, and cools the beverage container by storing ice, other cold insulation material, and a beverage container inside.

Therefore, with conventional cold storage devices, as the ice melts over time, the container becomes submerged in water, which can cause water to enter the container and dilute the beverage inside, or water to mix with the beverage and cause the product to deteriorate. It may lose its value.

In addition, because the temperature distribution inside the box frame is uniform, some of the containers stored inside the device may
Some items may not be cooled depending on their location within the device. In particular, when using a cold insulating material such as dry ice or cold storage material, the container may cool 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. There have also been accidents where cap seals have been destroyed by the cold insulation material due to vibrations during transportation, collisions during removal, etc.

In view of these inconveniences, it has been considered to assemble a metal holder provided with a cooling fan around the upper inner periphery of the box frame.

This is a structure in which a cold insulating material is housed in a holding body, and the cold air from the cold insulating material is supplied into the box frame body through a cooling fan to cool the inside.It solves the above-mentioned disadvantages. It is extremely effective.

<Problems to be solved by the invention> However, since the above-mentioned holder is in the shape of a square ring that is assembled around the upper inner periphery of the box frame,
It is difficult to join the bent parts, and it is necessary to separately install a mechanism to support the holder in the upper part of the box frame. In some cases, a dead space is formed, and furthermore, it is difficult to handle.

<Means for Solving the Problems> The present invention was devised to solve the above-mentioned problems, and includes a thin case inside the entire circumference of the upper end of the insulating box frame whose top surface is open. A cold storage device configured by assembling a plurality of holders into a framework, each of which houses a cold insulation material, has a fin member on its lower surface, and has a protruding locking piece on its side edge that locks onto the upper end of the box frame. It is.

<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 around the entire circumference within the upper end portion of the box frame body 2.
This is a configuration in which a holder 3 is assembled.

The above-mentioned box frame 2 is, for example, as shown in FIG. 3, a box frame 4 whose top is open and whose four sides and bottom are integrally molded with a heat insulating board made of polystyrene foam or other material, and whose inner and outer surfaces are made of hard synthetic material. A sheet material 5 made of resin is attached.

On the other hand, in the embodiment shown in FIG. 1, the holder 3 is a long material in the shape of a narrow casing made of extruded aluminum, for example, and has side walls 7 erected on both side edges of the bottom wall 6, and side walls 7 on both sides. A top wall 8 is provided at the upper end of 7.

A large number of fin members 9 are provided along the length direction on the lower surface of the bottom wall 6, and one end of the top wall 8 is extended outward and bent downward at a right angle to form a locking piece 10. Further, a large number of partition walls 11 are provided along the length direction on the upper surface of the bottom wall 6, which is the inside, and a cold insulating material A such as dry ice or cold storage material is stored between the partition walls 11.

Note that the openings at both ends of the holder 3 are closed by caps 12.

On the other hand, a locking groove 13 is formed along the length direction on the upper end surface of the peripheral wall 2a of the box frame 2.
By fitting and locking the above-mentioned locking piece 10 into the box frame 3 from above, the holding plate 3 is held along one side of the inside of the upper end of the box frame body 2.
Four of these holders 3 are arranged in combination within the upper end of the rectangular box frame 2 to form a rectangular ring shape.

In the embodiment shown in FIG. 3, a hard synthetic resin sheet material 5 on the inner surface side of the peripheral wall 2a of the box frame body 2 is made to protrude upward, and a locking groove 13 is formed on the outside of this protruding portion. In the embodiment shown in FIG. 4, a locking groove 13 is formed approximately in the center of the upper end surface of the peripheral wall 2a of the box frame body 2. Therefore, the protruding width of the locking pieces 10 that fit and lock into these locking grooves 13 is set in accordance with the position of the locking grooves 13.

Furthermore, in the embodiments shown in FIGS. 5 and 6, the locking piece 10 covers the entire upper end surface of the peripheral wall 2a of the box frame 2 and engages with the outside of the peripheral wall 2a, without particularly forming the locking groove 13. Furthermore, in the embodiment of FIG.
The top wall 8 is detachable via a locking member 14, making it easy to take in and take out the cold insulating material A.

Next, a lid frame 15 made of a heat insulating material is attached to the upper end of the box frame 2.
is attached so that it can be opened and closed via a hinge etc., and
A lid piece 17 is attached so that the opening 16 formed in the center can be opened and closed.

In the above structure, the inside of the box frame 2 is almost airtightly closed by the lid frame 15 and the lid piece 17, and the holder 3 is fitted into the upper end of the box frame 2. Therefore, the deformation of the box frame 2 is prevented, and the holder 3 has a locking piece 1 on the inner surface of the upper end of the box frame 2.
0, and furthermore, the holding body 3
Since the upper surface of the holder 3 is covered with a lid frame member 15 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.

Further, the holder 3 is a narrow cartridge type that is small and easy to handle, and can be attached and detached from the box frame 2 by simply locking or removing the locking piece 10.

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 a cold insulation effect, and since the holder is fitted into the upper end of the box frame, deformation of the box frame is prevented. Since the inner surface is tightly contacted, the above-mentioned airtight condition 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 and uniformly cooled and kept cold for a long period of time 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.

Furthermore, the holder that stores the cold insulation material is a narrow cartridge type, which is extremely easy to attach and detach from the box frame, and is small and easy to handle, creating a dead space even when cooling it in a freezer. It has many excellent functions and effects, such as never being damaged.
