Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a new cooler box that is useful mainly when being carried and used during leisure activities.

[Conventional technology]

BACKGROUND ART Conventionally, this type of cooler box is known, in which the wall surface is constructed by adhering a thermoplastic synthetic resin sheet to hard styrofoam.

[The problem that the idea attempts to solve]

The cooler box described in the prior art is inconvenient because it cannot be folded, and the lid is opened and closed by opening and closing a slide fastener, so there are concerns about the insulation of the slide fastener attachment point. There were defects such as difficulty in manufacturing as it was necessary to sew the thermoplastic synthetic resin sheets to each other in a state in which they were attached to rigid styrofoam.

The object of the present invention is to provide a new cooler box that eliminates the above-mentioned defects.

By pushing the bottom sheet 19 with the corner portions 9 fitted into the valleys formed between the columnar sealed hollow chambers 8, the entire peripheral edge surface of the bottom sheet 19 is placed on the bottom sheet 7. is placed in close contact with the inner peripheral surface of the box body 10 and in a removable state, and the lid 18 is placed in the opening of the box body 10.
By pushing the lid body 18 into a state in which the corners of the lid body 8 are fitted into the upper end portions of the valleys formed between the columnar hermetic hollow chambers 8 and can be pulled out, the entire peripheral edge surface of the lid body 18 is pushed into the box body 10. It is placed in close contact with the inner peripheral surface of the opening.

〔Example〕

In the embodiment shown in the figure, a cylindrical inner periphery sheet 2 made of soft thermoplastic synthetic resin is placed inside a cylindrical outer periphery sheet 1 made of soft thermoplastic synthetic resin, and the outer periphery sheet 1 and the inner periphery sheet 2 are spaced equally apart. Twelve belt-shaped hanging sheets 3 made of thermoplastic synthetic resin are arranged on the upper and lower sides thereof, and a donut-shaped upper sheet 4 made of soft thermoplastic synthetic resin and a donut-shaped lower sheet 5 made of soft thermoplastic synthetic resin are arranged on the inner periphery. A circular bottom sheet 7 made of soft thermoplastic synthetic resin is arranged on the lower surface of the inner space 6 of the sheet 2, and the outer edge of the hanging sheet 3 and the outer edge of the upper and lower double-sided sheets 4 and 5 are attached to the outer circumferential sheet 1 and the outer circumferential edges of the upper and lower double-sided sheets 4 and 5 are connected to the inner circumferential sheet 2. The inner edge of the hanging sheet 3 and the upper and lower double-sided sheets 4 and 5
By welding the peripheral edges of the and bottom sheets 7 with welders, communication is established between the upper and lower side edges of the hanging sheet 3 and the upper and lower double-sided sheets 4 and 5.
A right-bottom cylindrical box body 10 with a circumferential wall formed by a series of book-shaped sealed hollow chambers 8 and an expandable/expandable supply/exhaust plug 9 is constructed, and both left and right outer surfaces of the box body 10 are made of soft thermoplastic composite. Resin handle 11,
11' and separately, under the dodecagonal upper sheet 13 made of soft thermoplastic synthetic resin with concave curved sides on each side, there is attached a dodecagonal dodecagonal sheet 13 made of soft thermoplastic synthetic resin with concave curved sides on each side. The square lower sheet 14,
A cylindrical hanging member 15 made of a soft thermoplastic synthetic resin sheet is arranged between the upper sheet 13 and the lower sheet 14, so that the outer periphery of the lower sheet is connected to the outer periphery of the upper sheet 13, and the upper and lower sheets 13, A lid body 18 with an inflatable supply/exhaust plug 17 in which the inside and outside of the hanging member 15 are communicated through a through hole 16 by welding the upper and lower side edges of the hanging member 15 to 14 using welders, respectively.
In addition, the bottom pad 19 is constructed in the same manner as the lid 18, and the handle 20 is attached to the top surface of the lid 18, and the corner portion of the bottom pad 19 is inserted into the box body 10. By pushing the bottom pad 19 into the troughs formed between the columnar sealed hollow chambers 8, the entire peripheral edge surface of the bottom pad 19 is placed on the bottom sheet 7. The lid 18 is placed in close contact with the inner peripheral surface and in a removable state, and the corner of the lid 18 is placed in the opening of the box body 10 at the upper end of the valley formed between the columnar sealed hollow chambers 8. The entire circumferential edge surface of the lid body 18 is brought into close contact with the inner circumferential surface of the opening of the box body 10 by pushing the lid body 18 into a state where it is fitted into a position and into a state where it can be removed.

[Effect]

Box main body 10 via supply/exhaust plugs 9, 17
The box can be folded and carried by exhausting air from inside the box body 10, the lid body 18, and the sole body 19 through the supply/exhaust plugs 9, 17. After inflating the box body 10, lid 18, and bottom sheet 19 by supplying air with air, the bottom sheet 19 is pushed onto the bottom sheet 7 of the box body 10, and the box body 10
The stored items are stored by putting ice and stored items into the box, and then fitting the lid 18 into the opening of the box body 10, and opening and closing the lid 18 as necessary to remove the stored items. It is used for purposes such as entering and exiting.

[Effect of idea]

Since the present invention has the above-mentioned configuration, it can be used for the above-mentioned purposes.
In other words, it can be folded up into a small size when not needed, making it convenient to carry.Also, when the lid is closed, the storage space's top, bottom, left, right, front, and back walls are completely surrounded by hollow walls, making it highly insulative. There is no need to worry about heat insulation properties as in the conventional example, and there is no need to sew the sheets together when the thermoplastic synthetic resin sheet is attached to the rigid styrofoam as in the conventional example. It has excellent effects such as the fact that it can be manufactured simply by welding soft thermoplastic synthetic resin sheets together.
