Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to the structure of a cold storage container, and specifically relates to the lid structure of a synthetic resin container.

[Conventional technology]

Conventionally, many structures have been developed for cold storage containers made of synthetic resin foam that have unique features on the inside of the lid in order to attach a cooling medium. There is a cold storage container like No. 55-347.

A detailed description will be given below with reference to the drawings.

This cold storage container B is made up of a container body 1 and a lid 4 as shown in FIG. It is characterized by a structure in which a plurality of cooling containers 10 are formed to provide ventilation with the container body 1 side and cool the inside of the cold storage container B.

[Problem that the invention attempts to solve]

However, since the structure described above is such that the bottom 9 of the recess 8 provided in the lid 4 must support the entire weight of the cooling medium 6, the bottom 9 of the recess 8 provided in the lid body 4 is A large thickness is required, and it is impossible to provide a wide and large through hole 10 in terms of strength. Therefore, the bottom 9
The excessive thickness of the container B greatly narrows the storage space of the container B itself, and the small area of the through hole 10 has serious drawbacks such as poor air flow and poor efficiency due to the cooling medium 6 blocking the hole.

The present invention eliminates many of these drawbacks, and provides a cold storage container that has an extremely simple structure that is easy to mold, saves materials, takes up a large space, and has a large cooling effect.

[Means for solving problems]

As shown in FIG. 2, the present invention consists of a container body 1 and a lid body which is removably fitted onto the mouth part 2 above the container body 1 and has an opening 3 of an appropriate size in the upper part. 4, and a lid plate 5 that covers the opening 3 of the lid 4; A cooling container A made of foamed synthetic resin, which includes a cooling rod-shaped cooling container on a pair of opposite sides of the opening 3 of the lid 4; It is characterized by a protruding corrugated portion 7 having a plurality of recesses that serve as engaging portions for the medium 6'.

[Effect]

Due to the above-described configuration, the present invention has become suitable as a container for items that need to be kept cold.

The foamed synthetic resin cold storage container A of the present invention is designed to efficiently store and install a cooling medium 6' formed in a rod shape as shown in FIG. The lid body 4 is directly engaged with the end thereof to provide powerful cooling.

That is, when the cover plate 5 of the opening 3 provided in the cover body 4 is removed and the rod-shaped cooling medium 6' is inserted into the cold storage container A, a pair of opposing side surfaces of the opening 3 are inserted as shown in FIG. Both ends thereof are hooked on the corrugated portion 7 which is protruded from the wafer, and are respectively engaged with the recesses provided in the corrugated portion 7. Rod-shaped cooling medium 6' in this state
Since it maintains its shape due to its own rigidity, its both ends are firmly engaged and fixed, and it does not allow it to fall out of the recess. At this time, it is important that the pair of corrugated portions 7 are positioned such that the protruding facing dimension is shorter than the longitudinal dimension of the rod-shaped cooling medium 6'. The facing dimension of the side surface of the opening 3 is a rod-shaped cooling medium 6'.
Even if the width is wider than the longitudinal dimension, the protruding dimension of the corrugated portion 7 is equal to 1 in the longitudinal dimension of the rod-shaped cooling medium 6'.
Of course, the width must be within the added width dimension.

After arranging the required number of rod-shaped cooling media 6', the opening 3 is covered with the cover plate 5, and the installation is completed securely, resulting in a fixing structure that is extremely strong against vibrations, shocks, etc. during transportation.

In this way, the foamed synthetic resin cold storage container A equipped with the rod-shaped cooling medium 6'
Since the structure supports the entire weight only by the corrugated portion 7 of the opening 3 and does not place any burden on other members, it is easier to mold than the conventional method and is economical as it saves a large amount of material. In addition, since there is nothing blocking the cold air inside the cold storage container A, the cold air drops directly almost immediately after the rod-shaped cooling medium 6' is installed, so the temperature inside the cold storage container A is lowered within a short period of time, and the stored items are lowered within a short time. It becomes possible to cool down the water without any loss time. Further, since the cooling power directly acts on the stored items as described above, it is strong, and a strong cooling effect is exerted on every corner of the cold storage container A.

[Effect of idea]

As explained above, the present invention is ideal because it can accurately and firmly fix and store the cooling medium by providing a simple engagement part, and also has a high cooling capacity due to excellent internal ventilation. It is a cold storage container made of foamed synthetic resin.
