DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a case for accommodating a plurality of cold storage agents and freezing the cold storage agents.

(Prior art and its problems) In recent years, in the case of fresh foods, etc. shipped directly from the production area, a frozen regenerator is enclosed in a transportation case, and the fresh air is kept cool by the cold air emitted from the regenerator during transportation. While the method of transporting is often used, the cold storage agent used in such a transport method is one that is frozen and stored in advance in a freezer before transportation, and the cold storage agent is formed in a bag shape, In the prior art, a gel-like cold storage agent is enclosed. Conventionally, a large number of cold storage agents 52 are stored in an outer box 51 formed of cardboard as shown in FIG. A method of stacking 51 in a freezer to freeze a large amount of regenerator is used, and the outer box 51 is an outer box 51 located in a lower part when many are stacked in the freezer.
There is a case that the cold storage agent bag inside is damaged before it freezes, and the gel-like cold storage agent flows out.
There was a problem in strength. Further, in the exterior box 51 having the conventional structure, the circulation of cold air in the freezer is poor, and the cold storage agent 52 stored in the central portion of the exterior box 51 is difficult to freeze.

(Means for Solving the Problem) The present invention has been devised in view of the above-mentioned conventional problems, and provides a regenerator case having high strength and capable of favorably freezing the regenerator inside. For the purpose of
The gist thereof is a case for freezing a plurality of cool storage agents stored inside in a freezer, the case including an outer box formed in a box shape so as to be stackable in large numbers, and a corner portion in the outer box. And a hollow paper tube that is erected in a vertical direction, and is horizontally arranged in the outer box along the paper tube, and is composed of a plurality of pads each capable of mounting a regenerator on the upper surface side, A plurality of hook holes that can be opened by pressing with a finger are formed on the upper and lower edges of the outer box,
The paper tube and the pad are formed with cold air holes or the like for vertically circulating the cold air introduced into the outer box from the hook holes.

(Operation) The regenerator case is composed of an outer box, a paper tube arranged in a corner or the like in the outer box, and a plurality of pads horizontally arranged in the outer box. After the paper tube is erected at the corners of the box, etc., a pad is arranged along this paper tube, a plurality of cool storage agents are placed on the pad, and a pad is laid on the upper surface side of the cool storage agent. However, it is possible to place more than one cool storage agent on the upper surface side and store the cool storage agent in the outer box via the pads in multiple layers, and carry the outer box into the freezer in this state. At that time, the hook holes at the upper and lower edges of the outer box can be opened by pressing with fingers, and even when a plurality of outer boxes are stacked in the freezer, they are placed in the corners, etc. The core of the paper is used as a pillar to support the weight, and the strength of the outer box is secured. Since the cold storage agent stored inside is in a state of being partitioned by a plurality of pads, a good space is formed between the cold storage agents, and the cold air in the freezer is satisfactorily inside the outer box from the hook hole. Introduced into the cold storage, the cool air touches each regenerator, and the regenerator can be frozen well. Moreover, since the paper tube and the pad are formed with the cold air holes for circulating the cool air in the vertical direction, the introduced cool air can circulate well in the outer box to satisfactorily freeze the regenerator inside.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is an exploded perspective view of a cool storage agent case, and the cool storage agent case is an outer box 1 formed in a box shape by cardboard or the like.
And four paper tubes 2, 2, 2, 2 which are erected at the corners inside the outer box 1, and a plurality of paper tubes 2, 2, 2, 2 are horizontally arranged vertically along the paper tubes 2, 2, 2, 2. Put pads 3, 3,
3 and 3, and each of the pads 3 can have, for example, about five bag-shaped cool storage agents 4, 4, 4, 4 mounted on the upper surface side thereof. Therefore, a plurality of cool storage agents 4, 4, 4, 4 can be placed on the upper surface side of each pad 3, and the cool storage agents can be stacked inside in a plurality of layers in a stack.

The outer box 1 has a structure as shown in FIG. 2, for example, and a plurality of cold air holes 1b, 1b, 1b are provided on the peripheral surface side thereof.
The cold air in the freezer can be introduced into the interior through the cold air holes 1b. Further, perforations M are formed in a hook shape at the upper edge and the lower edge of the outer box 1. Along the perforations M, as shown in an enlarged view in FIG. The structure is such that the hook hole portion 1a opened in a notch shape can be easily formed by pressing the eye M to press it. When the hook hole portion 1a is opened with a finger, cool air is introduced into the inside well also from the hook hole portion 1a.

Further, the paper tube 2 has a structure as shown in FIG. 3, and is made of a hard paper material that can stand upright in a hollow shape, and its thickness can withstand a weight of about 1 t, for example. It is formed to a thickness that allows it. The paper tubes 2 are erected at the corners inside the outer box 1, and may have a cylindrical shape or a quadrangular prism shape. In addition, the upper and lower end portions of each paper tube 2 are recessed into the peripheral edge portions.
a, 2a, 2a are formed, and cool air can flow from the recess 2a into the paper tube 2. Also, paper tube 2
A plurality of cold air holes 2b, 2b through which cold air can flow are also formed in the peripheral edge portion of the.

Further, the pad 3 has a shape as shown in a plan view in FIG. 5, and the corner portions of the pad 3 are formed with recessed corner recesses 3a, 3a, 3a, 3a,
Each of the corner recesses 3a can come into contact with the peripheral edge of the paper tube 2. Further, a plurality of cold air concave portions 3b, 3b, 3b are formed in the peripheral edge portion of the pad 3 to form a cold air flow passage. Further, cold air holes 3c, 3c through which cold air can flow are also formed in the central portion. Therefore, the pad 3 can be horizontally arranged in the outer box 1 along the paper tubes 2 provided upright at the corners of the outer box 1, and at this time, the inner wall surface of the outer box 1 and the outer periphery of the pad 3 can be arranged. Even if the surfaces come into contact with each other, the cold air concave portions 3b, 3b, 3b are formed, so that a cool air flow passage is favorably formed with the outer box 1. Therefore, a plurality of bag-shaped cool storage agents 4 are placed on the upper surface of the pad 3, another pad 3 is laid on the upper surface, and a plurality of cool storage agents 4 are placed on the upper surface side. Further, another pad is laid on the upper surface side, and a plurality of cool storage agents 4 are placed on the upper surface side so that the cool storage agents 4 can be stacked in the outer box 1. ，
3, the space is formed well in the vertical direction. Pat 3
A protrusion or the like may be formed on the upper surface side of the container to prevent the cold storage agent 4 from moving, so that the cold storage agent 4 placed on the pad 3 when the outer case 1 is transported can be properly displaced. Can be prevented.

In this way, the outer box 1 is carried into the freezer in a state where the cold storage agents 4 are stacked in a plurality of layers inside, and at that time, as shown in FIG. 4, it is pressed along the perforation M with the thumb or the like. By opening the hook holes 1a, 1a, 1a, a plurality of outer boxes 1 can be stacked, and a large number of outer boxes 1 can be arranged in a stacked shape by effectively utilizing the space in the freezer. At that time, the outer box 1 is formed by the paper tubes 2, 2, 2, 2.
Since the strength of the cold storage agent is reinforced, the outer case 1 at the lower portion is not crushed, and the conventional accident of damaging the cold storage agent is prevented. Further, the cool air in the freezer is introduced into the inside better than the hook holes 1a and the cold air holes 1b of the outer box, and the introduced cold air is the cold air concave portion 3b and the cold air hole 3 of the pad 3.
The cold storage agent 4 can be satisfactorily frozen by cold air by passing through c in the vertical direction, and cold air can be satisfactorily circulated through the recesses 2a and the cold air holes 2b of the paper tube 2 even at the corners. As a result, the cool air is circulated well in the outer box 1, and the problem that the cool air does not reach the cool storage agent arranged in the central portion and the freezing of the cool storage agent in the central portion is delayed as in the conventional case is well solved.

As shown in FIG. 6, a square hole 3H may be formed in the center of the pad 3, and the cylindrical paper tube 2 may be arranged in the square hole 3H. As shown in FIG. 7 in an enlarged manner, the gap S formed between the rectangular hole 3H and the outer periphery of the cylindrical paper tube 2 can be used as a flow passage for cold air.

(Effect of the Invention) The cold storage agent case of the present invention is a case for freezing a plurality of cold storage agents stored inside in a freezer, and the case is an outer box formed in a box shape so as to be stackable in large numbers. When,
Hollow paper tubes standing upright at respective corners and the like in the outer box, and a plurality of paper tubes arranged horizontally along the paper tube in the outer box and capable of mounting the cool storage agent on the upper surface side thereof. A plurality of hooks are formed at the upper edge and the lower edge of the outer box by pressing with a finger, and the paper tube and the pad have the above-mentioned structure. By forming cold air holes and the like for circulating the cool air introduced into the outer box from the hook holes in the vertical direction, the outer box is reinforced by the paper tube and the strength when stacked is increased,
Crushing does not occur. Further, since the cool air is satisfactorily introduced and circulated inside through the hook holes formed in the outer box and the cold air holes formed in the paper tube and the pad, the regenerator stored inside is uniformly cooled. The problems such as the delay of freezing of the cool storage agent in the central portion as in the conventional case are well solved. Further, since the hook hole can be easily opened with a finger just before using it in the freezer, it prevents dust and dirt from flowing into the inside during transportation and makes it easy to use before use. The cold regenerator can be quickly opened in a good state by allowing the cold regenerator to act as a cold air introduction hole.
