Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a regenerator, and more particularly, to a regenerator that can be used by connecting a plurality of regenerators.

[0002]

[Prior art]

 For example, when fresh food or the like is transported or stored in a cooled state, a regenerator body containing a regenerator in a plastic container may be used. As this regenerator, it is known that a regenerator is filled in a hollow container made of a synthetic resin such as polyethylene formed into a plate or block having an appropriate size. As the cold storage agent, an aqueous solution of an inorganic salt such as sodium chloride, an alcohol aqueous solution such as methanol, or a gel-like material prepared by adding a known gelling agent to a water-soluble polymer is used. . The regenerator is frozen in advance to solidify the regenerator therein, and an appropriate number of the regenerator is placed in a container or the like in which the fresh food is stored to keep it cool.

By the way, depending on the type of object to be cooled, the transportation distance, etc., it may be necessary to keep cold for a long time. Therefore, it is conceivable to make one regenerator large-sized, but if it does so, it will take a long time to solidify the regenerator inside, which is uneconomical. In addition, a plurality of regenerators are sometimes tied with a string or the like, but in that case, it takes time to assemble and disassemble.

On the other hand, a protrusion and a recess that can be engaged with another cool storage body are formed in the hollow container of the cool storage body, and a plurality of cool storage bodies are connected by the engagement of the protrusion and the recess. The one to be used is also proposed. In this cool storage body, since the coolant is also stored in the engaging projections and recesses, the projections and recesses are also in a low temperature state, and the strength is reduced. In addition, since a force is concentrated on the protrusion and the recess when the regenerator is connected, there is a problem that the protrusion and the recess are easily broken or cracked. In addition, the cold storage agent in the engaging projection and the recess may expand due to freezing, which may cause the damage, and the cold storage agent may leak from the damaged portion.

[Problems to be solved by the device]

 The present invention has been proposed in view of the above problems, and provides a regenerator with no risk of damage to the regenerator and capable of easily and reliably coupling and disassembling a plurality of regenerators. Is what you are trying to do.

[0006]

[Means for Solving the Problems]

 There are two cold storage bodies proposed here. That is, the first regenerator is a regenerator in which a regenerator is contained in a plastic hollow container, and the reversible container wall surfaces of the retentate are closely integrated so that the regenerator does not exist inside. A hollow part is partially formed, and a connecting locking piece insertion hole is formed penetrating the non-hollow part, and a connecting locking piece projecting on the outer surface of the wall surface of the container and having no cold storage agent inside. However, it is characterized in that it is connected to another regenerator by the connection locking piece insertion hole and the connection locking piece.

The cool storage body of the second invention is a cool storage body in which a cool storage agent is contained in a hollow container made of plastic, and the container has two surface wall surfaces facing each other and a wall surface for the surface. The non-hollow part is formed of a flat hollow body composed of a side wall that is connected to the peripheral edge, and the facing wall is intimately integrated to partially form a non-hollow part where the regenerator does not exist inside. A connecting locking piece insertion hole penetratingly formed in the side wall, and a connecting locking piece protrudingly formed on the outer surface of the side wall surface and having no regenerator inside, and connected to the connecting locking piece insertion hole. It is characterized in that it is connected to another regenerator by a locking piece.

【Example】

 Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. In the second invention, the container wall surface in the first invention is composed of two facing wall surfaces and a side wall surface that is connected to the peripheral edge of the surface wall surface. Since only a part of the configuration is limited, such as a container made of a flat hollow body with and, only the first device is described in the following description.

FIG. 1 is a perspective view showing an example of use of the regenerator of the first and second inventions, FIG. 2 is a perspective view of the regenerator, FIG. 3 is a sectional view taken along line 3-3, and FIG. 4 is a cross-sectional view taken along line 4-4, and FIG. 5 is a cross-sectional view showing a main part when locking the regenerators.

As shown in FIG. 1 to FIG. 3, the regenerator 10 of the present invention contains a regenerator 12 in a hollow container 11 and freezes and solidifies the regenerator 12, As shown in the figure, a suitable number of blocks are connected and used in a container or cooler box containing the object to be cooled.

The hollow container 11 is formed by blow molding an appropriate plastic such as polyethylene into a substantially rectangular flat hollow body having a hollow portion for containing the regenerator 12 therein. In this hollow container 11, a container wall surface 11A is constituted by two facing surface wall surfaces 11a, 11a and a side wall surface 11b connected to the peripheral edge of the surface wall surface 11a. The hollow container 11 is formed into a flat hollow body having an appropriate size by the wall surfaces 11a and 11b, and the non-hollow portion 14 in which the surface wall surfaces 11a and 11a are closely adhered to each other is formed. Partially formed. In the first invention, the shape of the hollow container 11 is not limited to the flat shape, and the position of the non-hollow portion 14 is not limited to the surface wall surfaces 11a, 11a.

The non-hollow portion 14 is a concave portion in which the thickness of the bottom surface is increased by partially adhering the opposing surface wall surfaces 11 a, 11 a integrally, and the cold storage agent 12 does not exist inside. Since the inner wall of the non-hollow portion 14 is formed in a rib shape on the hollow container 11 and the regenerator 12 does not exist as described above, the strength of the hollow container 11 is increased, and the container due to contact or friction is increased. Can be prevented from being damaged. The non-hollow portions 14 are provided in three rows in the vicinity of both ends of the facing wall surfaces 11a, 11a along the longitudinal direction. The non-hollow portion 14 is formed of an oval concave portion on the inner circumference thereof, and has a connecting and locking piece insertion hole 15 provided near one end thereof. The connection locking piece insertion hole 15 is for inserting and connecting the connection locking piece 16 of the other regenerator 10, and as shown in FIGS. 2 and 3, penetrates the non-hollow portion 14. Has been formed. In this example, as shown in the figure, one is provided for each non-hollow portion 14.

On the other hand, on the outer surface of the side wall surface 11b of the hollow container 11, a coupling locking piece 16 is formed to project. The connection locking piece 16 is inserted into the connection locking piece insertion hole 15 to connect a plurality of regenerators 10, and is composed of a non-hollow portion in which the regenerator 12 does not exist. In this embodiment, three side wall surfaces facing each other in the longitudinal direction of the regenerator 10 are provided, and the positions thereof are preferably aligned with the positions of the connecting locking piece insertion holes 15. Thereby, it is convenient for connection with other regenerators. This connecting locking piece 16 may be provided on the wall surface 11 a for the surface of the hollow container 11. Further, in the first invention, the position of the connecting locking piece 16 is not limited, but is set to a position corresponding to the connecting locking piece insertion hole 15. The non-hollow portion 14 and the connecting locking piece 16 are easily formed when the hollow container 11 is formed by forming a predetermined position of a molding die of the container into an appropriate cavity shape. be able to.

A substantially U-shaped locking claw 17 is provided at the tip of the connecting locking piece 16. When the connecting locking piece 16 is inserted into the connecting locking piece insertion hole 15, this locking claw 17 locks on the locking surface 18 of the non-hollow portion 14 described below, and the locking claws 17 of the cold storage bodies 10 are connected to each other. It is for ensuring the engagement.

The locking surface 18 is formed between the coupling locking piece insertion hole 15 and the other end of the non-hollow portion 14 in which the coupling locking piece insertion hole 15 is provided, and the wall surfaces 11 a, 11 a. Due to the close adherence, the cold storage agent 12 does not exist and is thick. The locking surface 18 is for engaging the locking claw 17 of the connecting locking piece 16 and constitutes a bottom surface portion of the concave non-hollow portion 14.

The size of the connection locking piece insertion hole 15 and the size of the connection locking piece 16 can be appropriately set depending on the shape of the regenerator, etc., but can be reliably and easily connected to another regenerator 10. In order to achieve this, as shown in FIGS. 4 and 5, the length a of the connecting locking piece insertion hole 15 is made longer than the length b of the connecting locking piece 16 and the connecting locking piece insertion hole 15 is formed. If the thickness d of the connecting and locking piece 16 is made thinner than the width c, the insertion is easy. Further, if the length f of the locking surface 18 is made longer than the length e of the locking claw 17, the locking claw 17 is reliably locked to the locking surface 18, so that the regenerator 10 is reliably connected. be able to. Furthermore, if the width g of the locking claw 17 and the depth h from the wall surface 11a to the locking surface 18 are made substantially equal, the coupling locking piece 16 is inserted into the coupling locking piece insertion hole 15 and the regenerator 10 is cooled. Since the connecting engagement piece 16 does not project from the connecting engagement piece insertion hole 15 when connecting, it is stable and suitable when the connected regenerators are stacked.
