Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to leisure activities such as fishing.
And a manufacturing method thereof.

[0002]

2. Description of the Related Art Heretofore, cold storage containers used for fishing and other types of leisure have mainly been formed of a hard plastic outer surface. However, in addition to being heavy and bulky, these cold containers had the same appearance in almost any cold box. For this reason, recently, a cool box using a woven cloth or a decorative sheet such as a leather sheet on the outer surface has been used.

[0003] These cold insulation boxes are mainly provided with a cold insulation lid body having skirts formed on the periphery thereof, and the lid body is formed into a bag shape with the front and back of the makeup sheet, and the inside thereof. A heat insulating material having flexibility is put in. Therefore, when a skirt is formed on the lid for cold insulation, the corners of the makeup sheet are pinched and closed, so that a crease or a sewn trace of the makeup sheet is formed at the corners. It is not very desirable in appearance. Moreover, the sewing work for forming these skirts is troublesome. Further, the flexible heat insulating material put in the bag-shaped lid body is made into a skirt by continuously entering the bag in the skirt portion.
Since the skirt portion cannot be maintained in the shape of the skirt due to the elasticity of the heat insulating material placed in the seat portion, the heat insulating material separate from the top plate portion is placed in the skirt portion. However, if a heat insulating material separate from the top plate is inserted in the skirt, there is a drawback that the heat insulating effect is lost at the boundary between the skirt and the top.

[0004]

The problems to be solved are that the folds and stitch marks of the cosmetic sheet formed at the corners of the lid are not preferable in appearance, and the skirt of the lid is not preferable. -It takes a lot of time to sew the work to form the skirt, and if a heat insulator that is separate from the top plate is put in the skirt of the lid, the skirt is insulated at the boundary between the skirt and the top plate. The effect will disappear.

In view of the above-mentioned drawbacks, an object of the present invention is to form a lid body having a skirt having a heat insulating plate on its periphery by using a synthetic resin heat insulating plate which can be deformed by heat and pressure to deform it. It is an object of the present invention to propose a cool container that is good, is easy to manufacture, and is hard to leak cold air from a lid, and a manufacturing method thereof.

[0006]

SUMMARY OF THE INVENTION The present invention is a peripheral skirt.
In manufacturing a cold insulation container having a lid body having a cover formed thereon, a skirt is formed on the lid body by stacking a heat-deformable synthetic resin heat insulating plate with a flexible makeup sheet and subjecting it to heat-pressure deformation. The idea is to have formed it.

[0007]

As shown in FIGS. 1 and 2, the lid 6 has a curved top plate portion 6a and a skirt 6b integrally formed on the periphery thereof.
An edge tape 11 is sewn on the edge of 6b. This lid 6
The synthetic resin heat insulating plate 8 of is deformed by heat and pressure and integrally formed with the top plate portion 6a
And the skirt 6b are formed, and the skirt 6b is maintained without being opened outward. Flexible synthetic sheets 9 and 10 which are stacked on the upper and lower sides of the synthetic resin heat insulating plate 8 are also provided so as to match the shape of the synthetic resin heat insulating plate 8.
The surface of the lid 6 having a top plate portion and skirts formed by heat and pressure deformation is covered with a decorative sheet 9 without wrinkles so as to match the top plate portion and skirts, and the back surface is also the same. Covered with makeup sheet 10 without wrinkles. Therefore, makeup sheets 9 and 10
Since there are no folds or overlapping portions at the corners or the like of the lid, it is preferable in terms of appearance. When the container body 1 is covered with the lid body 6, the upper periphery of the container body 1 is covered with the skirts 6b of the lid body 6 so that cold air does not easily leak from the peripheral edge.
