キヤビテイ面１６の形状に合せて成形するブロー
成形法が一般に採用されている。(Problems to be Solved by the Invention) When the cold storage plate as described above is made of synthetic resin, it is extruded into a cylindrical shape into two or more split molds 15, 15a as shown in FIG. After charging the parison (material) 17 into the mold and closing the mold, a medium such as compressed air is blown into the parison to form the parison 17 in the molds 15 and 15a.The shape of the cavity surface 16 is A blow molding method is generally adopted.

ばならない。 Therefore, when forming a container with a closed structure like the cool storage plate 11, the bottom 17a and the mouth 17b of the cylindrical parison 17 are welded to form a bag-like shape before being inserted into the molds 15, 15a or into the mold. It must be closed and shaped.

れたりするといつた不具合があつた。 However, since the cold storage plate 11 undergoes a volume change due to repeated heat storage (cooling) and heat radiation of the cold storage agent,
The sides of the cold storage plate 11, especially the mating surface 14 between the bottom part 17a and the mouth part 17b, which are welded during blow molding and have weak adhesive strength, have problems such as being deformed or cracked by the expansion force from inside.

冷板の外側面を中心に生じてしまう。 Furthermore, even if the cold storage plate is made of metal and formed using a different method, if the same shape is used, deformation (permanent deformation) due to the expansion force from inside will still occur mainly on the outer surface of the cold storage plate. It ends up.

形、割れを防止したものである。(Means for Solving the Problem) Therefore, this invention forms concave curved grooves that curve toward the inside of the cold storage plate on the outer surface of the cold storage plate, especially on the mating surface of the cold storage plate, in the cold storage agent that fills the cold storage plate. Then, by making the length of the side surface of the cold storage plate longer than the thickness of the cold storage plate, the expansion of the cold storage agent is absorbed by the shape change of the concave curved groove, and the expansion of the cold storage agent is applied from the inside of the cold storage plate to the side surface of the cold storage plate, especially the mating surface part. This reduces the expansion force to prevent deformation and cracking of the cold storage plate.

A concave curved groove 4 is formed in the inside of the groove.
したがつて、蓄冷板１の側面３の長さｌは蓄冷
板１の厚さＬよりも長くなつている。 Therefore, the length l of the side surface 3 of the cool storage plate 1 is longer than the thickness L of the cool storage plate 1.

る。(Effects of the invention) According to this invention, a concave curved groove is formed on the outer surface of a synthetic resin or metal regenerator plate, particularly on the mating surface of the regenerator plate, and is curved toward the inside of the regenerator plate. Since the length of the regenerator is longer than the thickness of the regenerator plate, the regenerator deforms three-dimensionally as the regenerator expands during cold storage (cooling). It can be absorbed by changing the shape of the groove, so it can be absorbed from the inside of the regenerator plate to the outer surface of the regenerator plate,
In particular, by reducing the expansion force applied to the mating surfaces of the cold storage plates, it is possible to prevent the cold storage plates from deforming or cracking.
また、蓄冷板の合せ面部に凹曲面溝を設けた場
合、合せ面部にバリが出てもあまり目立たないか
ら蓄冷板の外観も美麗となる。 Further, when a concave curved groove is provided on the mating surface portion of the cold storage plate, even if burrs appear on the mating surface portion, they are not so noticeable, so that the appearance of the cold storage plate becomes beautiful.
