(1) Cold storage agent-filled container with handle The cold storage agent-filled container with handle includes a container 1, a handle 2, and a cold storage agent 3.
(FIG. 1). The container 1 is a resin molded product made by blow molding, and is a hollow disk-shaped body provided with a hollow portion O. By placing this container 1 on the step surface 42 of the cool box 4 as a substantially rectangular plate as shown in FIG. 1, a lid can be perfectly fitted to the opening surface of the cool box 4 without forming a gap ε as shown in FIG. The size of the container 1 is adapted to the size of the opening of the cool box 4 on the user side.
It becomes a square board of about mm x height 22mm. A depression 11 is formed on the upper surface of the container 1. The depression 11 here is a rectangular depression 11 substantially at the center of the container 1. In this embodiment, the size of the depression 11 is about 60 mm long × 100 mm wide × 15 mm high. Then, a pair of small holes 12 that are recessed toward the hollow portion O are formed on the facing upright wall surface (here, the wall surface facing in the longitudinal direction) that forms the depression 11. The small hole 12 is a horizontal hole provided near the opening edge of the depression 11, and is a square depression as shown in FIG. Reference numeral 13 denotes a nozzle for injecting a cold storage agent provided on one side of the container 1, and reference numeral 14 denotes a flange for fixing and holding the nozzle 13 to the container body. As the material of the container 1, HDPE (high-density polyethylene) or the like adopted in the present embodiment is suitable. HDPE has cold resistance of about −20 ° C. necessary for cold storage and delivery, has excellent moldability, and is inexpensive.

The handle 2 is a rod-shaped body and has a square pillar-shaped handle body 21.
And small projections 22 provided on both end surfaces thereof. The handle body 21 has a length equal to the horizontal length (100
mm), the width W is set to about 20 mm to make it easy to grasp by hand. The small projection 22 is a square pillar projection that fits into the small hole 12, and is, for example, a square having a length of A5 mm and a width of B5 mm and having a protrusion C of about 2 mm (FIG. 5). The small projections 22 are fitted into the small holes 12, and the container 1 and the handle 2 are integrated and integrated. Specifically, the small projections 22 of the handle 2 are inserted into the small holes 12 immediately after the container 1 is made by blow molding, and the container 1 and the handle 2 are connected and integrated by shrinkage of the container 1 after blow molding. . The material of the handle 2 is not particularly limited, but is preferably of the same quality as the handle 2 so as to be integrated with the container 1.

[0010] The regenerator 3 is used for water having a large latent heat of fusion and a large specific heat.
It is a known cold storage agent blended with a thickener, a preservative and the like that can withstand long-term repeated use. After injecting the cold storage agent 3 from the nozzle 13 into the hollow portion O of the container 1, the nozzle 13
And the regenerator 3 is sealed in the hollow portion O of the container.

(2) Manufacturing method of a container with a handle for charging a regenerator A handle 2 is first prepared for a container with a handle for charging a regenerator.
The handle 2 has a rod shape as described above, and has small protrusions 22 formed on both end surfaces. Handle 2 has the same HDP as container 1
It is made of a material such as E in advance by blow molding. Then, the aforementioned container 1, that is, the hollow portion O for charging the regenerator
The container 1 is formed by blow molding in the shape of a hollow disk provided with a recess 11 having a recess 11 formed on the upper surface thereof and a small hole 12 formed in an opposed upright wall surface for forming the recess 11. The container 1 is blow-molded with a split mold because the recess 11 has a small hole 12.

Next, immediately after the container 1 is manufactured by blow molding, before the container 1 is cooled, the handle 2 prepared in advance is incorporated. The small projection 22 of the handle 2 is fitted into the small hole 12 of the container 1 within 30 seconds to 1 minute after the molding of the container 1 (FIGS. 3 and 4).

Subsequently, the container 1 and the handle 2 are connected and integrated by shrinkage of the container 1 by cooling and solidification. In blow molding, a parison in a molten state expands by air pressure, and then is cooled to form a molded product. However, the specific volume after cooling and solidification is smaller than the specific volume in the molten state of the resin. That is, the molten resin contracts at the stage of cooling and solidification. In the present invention, the container 1 and the handle 2 are connected and integrated by utilizing this shrinkage caused by cooling and solidification of the container. In the case of the HDPE material of the present embodiment, the molding shrinkage (ASTM D-955) is 2 to 5%. Now, assuming that the molding shrinkage of HDPE is 3%,
Since the lateral length of the depression 11 is 100 mm, it is reduced by about 3 mm. The small projections 22 provided at both ends of the handle body 21 having a length of 100 mm have their protrusions C due to molding shrinkage.
About 2 mm fits into the small hole 12 and cannot be removed anymore after the container 1 has cooled to room temperature. Thus, a desired container with a handle for charging a regenerator is completed. After that, the cold storage agent 3 is injected from the nozzle 13 and the nozzle 1
When the container 3 is sealed, a cold storage agent-filled container with a handle is completed (FIG. 1).

(3) Effect According to the method for producing the cold storage agent-filled container with a handle and the cold storage agent-filled container with a handle configured as described above, the container 1 filled with the cold storage agent 3 and the gap ε as shown in FIG. , The entire surface of the opening of the cool box 4 can be covered. Since there is handle 2,
Even if the entire opening is covered and covered, the handle 2 can be easily removed by grasping the handle 2. This refrigerating container filled with a handle could also be easily removed with one hand. Of course, since the handle 2 is provided, attachment to the cool box 4 becomes easy. Furthermore, handle 2
Are fitted and integrated during the shrinkage of the container 1 so that they do not come off once fitted. And
When the opening of the cool box 4 is entirely covered with the cold storage container with a handle, the food in the cool box 4 can be uniformly kept cool and the escape of cold air from inside the cool box 4 to the outside of the cool box opening can be prevented. Improve performance. Actually, the cold storage container filled with the handle is provided in the cool box 4 as shown in FIG. 6 and covers the entire opening thereof, so that the product temperature in the cool box 43 is maintained at a predetermined temperature or lower for a predetermined time. Was completed.

The present invention is not limited to the embodiment described above, but can be variously modified within the scope of the present invention depending on the purpose and application. The shape, size, material, number, and the like of the container 1, the handle 2, the regenerator 3, and the like can be appropriately selected according to the application.
