Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container structure for accommodating a regenerator which has been improved so as to have an increased surface area in order to improve the cooling and heat radiation efficiency of fresh food such as vegetables and fish.

[0002]

2. Description of the Related Art As a container structure for accommodating such a cool storage agent, there is a cool storage container with a cool storage body described in JP-A-11-257815. In this cold storage container, when a plurality of regenerators are stacked one on top of the other, the concave-convex joint for positioning is performed by fitting a cylindrical small-diameter cylinder and a large-diameter cylinder. .

[0003]

The small-diameter cylinder and the large-diameter cylinder are specially formed as joints in the regenerator, and there is no regenerator at the joints. It does not contribute to heat dissipation. For this reason, there is a drawback that the joined portion is hardly directly linked to an increase in the cold storage capacity.

The present invention has been made in view of the above circumstances, and an object thereof is to form a concave portion and a convex portion on the lower surface of a container so as to increase the surface area and improve the cooling and heat radiation efficiency. An object of the present invention is to provide a container structure for accommodating a cold storage agent, which can contribute to long-term cooling by combining two containers by fitting with a convex portion.

[0005]

According to a first aspect of the present invention, there is provided a flat plastic material in which a regenerator is accommodated inside, and a large number of concave portions and convex portions are formed on a lower surface of the plastic material at predetermined intervals so as to protrude in the vertical and horizontal directions. It is characterized by comprising a container.

(Regarding the second aspect) The container is characterized in that two of the containers are vertically overlapped and the concave portion and the convex portion are fitted together.

[0007] (Claim 3) The container is characterized in that a plurality of reinforcing studs connecting the upper surface and the lower surface are provided in a zigzag shape.

(Claim 4) The cold storage agent inlet of one of the two stacked containers and the cold storage agent inlet of the other container are located opposite to each other. Features.

[0009]

According to the first aspect of the present invention, since a large number of concave portions and convex portions are formed on the lower surface of the container, the surface area of the entire container is increased, and the cooling and heat radiation efficiency is improved. Therefore, the cold storage material itself can be frozen in a relatively short time, and the object to be cooled can be kept in a cold state in a relatively short time. Also, when freezing the regenerator in the freezer, the container comes into contact with the inner wall of the freezer via a projection,
The flow path of the cool air by the concave portion can be secured between the container and the inner wall portion. Also, since the protrusion itself also stores the regenerator,
It can contribute to cooling and heat radiation. This projection is
Since the contact area with the object to be cooled is small, freezing and the like of the object to be cooled can be prevented as much as possible.

[0010] (Claim 2) By combining two containers vertically one on top of the other and by fitting the concave and convex portions, the containers are integrated in a state where the movement in the vertical and horizontal directions is restricted, and the heat is kept for a long time. Can be performed.

(Regarding Claim 3) Since the container is provided with a reinforcing stud for connecting the upper surface and the lower surface, the container is not crushed by an external force during handling.

(Claim 4) The cold storage agent inlet of one of the two stacked containers and the cold storage agent inlet of the other container are located opposite to each other, so that the design balance is achieved. Has taken.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to the drawings. In FIG. 1, reference numeral 1 denotes a flat rectangular container which stores a regenerator to keep a cold object cold. The container 1 is made of a plastic material such as polypropylene or polyethylene, and has a width of 28 mm.
It is formed to have a length of about 0 mm, a length of 135 mm, and a thickness of about 25 mm.

On the upper surface 2 of the container 1, there is formed a mold addressing portion 3 at the time of blow molding. On the lower surface 1a of the container 1, a large number of convex portions 4 corresponding to the mold destination portions 3 are formed so as to protrude in the vertical and horizontal directions at predetermined intervals as shown in FIGS. The projection 4 is, for example, about 20 mm long and about 25 mm wide.
mm and a height of about 25 mm. And
The depression formed between the projections 4 is referred to as a depression 5.

Numeral 6 denotes five reinforcing studs arranged in a zigzag shape, which connect the upper surface 2 and the lower surface 1a of the container 1 as shown in FIG. 4 so that the container 1 is not crushed by an external force during handling. ing. The number of these studs 6
It can be set arbitrarily as needed, in addition to five. Reference numeral 7 denotes a regenerator injection port, which is formed on a lateral side portion of the container 1 and is used for filling the regenerator therein. Reference numeral 8 denotes a main convex portion formed in the container 1 directly below the cold storage agent inlet 7, and 9 denotes a main concave portion formed on the side opposite to the cold storage agent inlet 7 so as to correspond to the main convex portion 8.

FIGS. 6 and 7 show (a) and (b) of FIG.
The two containers 1 are combined by overlapping the lower surfaces 1a of the same container 1 from the state of FIG.
Are automatically fitted to each other, and the movement in the vertical and horizontal directions is restricted to stop the movement. Therefore, the cooling capacity is increased, which is convenient for a large amount of cold-reserved materials or long-time cooling.

[Effects of the Embodiment] As described above, since the concave portion 5 and the convex portion 4 are formed in the container 1, the entire surface area of the container 1 is increased, and the cooling and heat radiation efficiency is improved. Further, when the refrigerating agent is frozen in the freezer, the container 1 comes into contact with the inner wall of the freezer via the convex portion 4, so that a flow path of cool air by the concave portion 5 is secured between the container 1 and the inner wall. Can be. In addition, since the protrusion 4 itself stores the regenerator, it can contribute to cooling and heat radiation. Since the convex portion 4 has a small contact area with the object to be cooled, freezing and the like of the object to be cooled can be prevented as much as possible.

Combining the two containers 1 vertically one above the other and fitting the concave portions 5 and the convex portions 4 to integrate them in a state where the movement in the vertical and horizontal directions is restricted, and to keep the cold for a long time. Becomes possible.

Since the container 1 is provided with the reinforcing stud 6 for connecting the upper surface 2 and the lower surface 1a, the container 1 is not crushed by an external force during handling.

The cold storage agent inlet 7 of one container 1 and the cold storage agent inlet 7 of the other container 1 of the two stacked containers 1 are located opposite to each other so as to balance the design. I am taking.

In addition, bread, cake,
Various fresh ingredients such as vegetables, fresh fish, eggs, meat, etc. may be used for transportation or storage by producers and distributors, or for personal or home use. You may. In addition, the material to be cooled is not limited to fresh ingredients,
It may be a sample or material for various medical treatments or experiments. In addition, in specific implementation, various changes can be made without departing from the gist of the present invention.
