Embodiments of the present invention will be described below in detail with reference to the drawings. 1 is a perspective view of the cooling storage 1 of the present invention, FIG. 2 is a front view of the cooling storage 1, and FIG. 3 is a cooling storage 1
FIG. 4 is a vertical cross-sectional view of one side of the heat insulation box 2 of the cooling storage 1.

The cold storage 1 of the present invention is used, for example, for keeping fresh food (goods) in the cold while mailing it, and when the goods are stored in the delivery base, the cold storage 1 and a truck or the like can be used. It is loaded on the bed of a delivery vehicle and transported. Then, after arriving at the delivery destination, the goods are taken out from the cooling storage 1 and delivered.

The cooling storage 1 has a main body composed of a heat insulating box 2 having an upper opening and a lower structure 3 attached to the lower surface of the heat insulating box 2. Insulated box 2
Is a steel plate (stainless steel) with an opening on the top surface as shown in FIG.
Box 4 and inner box 6 made of metal, a connection breaker 7 made of hard resin for connecting between upper ends of both boxes 4 and 6, and a space surrounded by these two boxes 4, 6 and breaker 7. And a polyurethane foam insulation material 8 filled by an in-situ foaming method.

In this case, an inward flange 4A is formed at the upper end of the outer box 4 after being bent inward at a right angle and then at a right angle downward. After being bent at a right angle to one side, an outward flange 6A is bent downward at a right angle. The breaker 7 has a substantially L-shaped cross section having an upper surface 7A and an inner surface 7B.
An engagement groove 7C that opens upward is formed inside the lower end of B.

First, with the upper surface 7A and the upper portion of the inner surface 7B of the breaker 7 in contact with the rear surface of the inward flange 4A of the outer box 4, the upper surface 7A is screwed onto the upper surface of the inward flange 4A from above. In this state, the inner box 6 is dropped into the outer box 4 from above and inserted, and the tip of the outward flange 6A is inserted into and engaged with the engaging groove 7C of the breaker 7 from above. As a result, the outer box 4 and the inner box 6 are connected with an interval therebetween.

An evaporation pipe 9 constituting a cooler of the cooling device R is attached to the side surface of the inner box 6 on the side of the outer box 4 (outer side) in a meandering manner with a fixture 11 made of a metal plate or aluminum tape. And has a heat conduction relationship with the inner box 6. In this state, the heat insulating material 8 is foam-filled between the two boxes 4 and 6, and the respective members are integrated to complete the heat insulating box 2.

The inside of the inner box 6 of the heat insulating box 2 serves as a storage chamber 12 as a storage room, and a hard synthetic resin breaker 13 for decoration is attached to the opening edge of the upper surface. The breaker 13 has a crank-shaped cross section including an upper side 13A, a vertical side 13B, and a lower side 13C, and the upper side 13A conceals a screw-fastened portion of the breaker 7.

The vertical side 13B and the lower side 1 of the breaker 13
3C is in intimate contact with the inward flange 4A of the outer box 4 and the surface of the breaker 7 and the outward flange 6A of the inner box 6, respectively. 14 are configured. Further, the vertical side 13B and the lower side 1B of the breaker 13 constituting this paragraph section 14
3C has a curved shape with a relatively large curvature, and a soft fin 16 projecting obliquely inward and upward at the tip of the lower side 13C by double extrusion molding.
3 and integrally formed.

The upper opening of the storage chamber 12 is openably and closably closed by the two heat insulating lid members 17 and 18. Each of the heat insulating lid members 17 and 18 has the same shape, and the periphery of the rectangular outer surface material 21 and the inner surface material 22 made of a steel plate (stainless steel) is connected by a hard synthetic resin frame member 23 to be inside. The heat insulating material 24 is filled.

A grip portion 26 is formed in a concave shape at the center of the outer surface member 21 of the heat insulating lid members 17 and 18, and
As shown in FIG. 5, seal portions 27, 27 made of a soft synthetic resin are integrally formed on the periphery of the frame member 23 by double extrusion molding at upper and lower portions, respectively.

At the same time, the case 29 and the cover 33 are fixed to the side of the inner box 6 by screwing the engagement flange 33A to the inner box 6.

As described above, since the case 29 for accommodating the cold storage agent 28 is composed of a member having a smooth inner surface with curved corners, even if the above-described vibration during transportation is applied to the cold storage agent 28, the bag will be The inconvenience of bursting can be avoided in advance.

Further, since the projections 29A, 29A having a curved sectional shape and projecting inward are bent and formed on the widest surface of the case 29, when the cold storage agent 28 freezes and solidifies as described later, The cool storage agent 28 and the protrusions 29A, 29A are in a form of engagement. Therefore, even if vibration is applied during the transportation as described above, the regenerator 28 does not shift, and can be stably and safely held.

Further, since the temperature sensor 32 is arranged between the protrusions 29A, 29A, the temperature sensor 32 is not
A and 29A are sandwiched between the regenerator 28 and the case 29, so that the temperature sensor 32 can be prevented from being displaced or falling off.

An inner surface plate 36 is attached to the inside of the case 29 accommodating the cold storage agent 28 at a distance from the case 29.
