[0037] figure 1 A first embodiment of a heat-insulating synthetic resin container (hereinafter referred to as a heat-insulating container) and a heat-insulating synthetic resin cover (hereinafter, a heat-insulating cover) according to the present invention, which is a partition The hot tableware includes a heat-insulating container 1 and a heat-insulating cover 21 covering the upper opening of the heat-insulating container 1 .

[0038] The insulated container 1 is formed as a double-walled bowl, which includes an outer container 2 and an inner container 3 . The diameter of the inner surface of the outer container 2 is larger than the diameter of the outer surface of the inner container 3 , and a heat insulating material 5 is filled in the space between the outer container 2 and the inner container 3 to form a heat insulating layer 4 . The outer container 2 and the inner container 3 are made of a synthetic resin having chemical resistance and gas barrier properties by injectio...

example 1

[0087] manufacture figure 1 Insulated container 1 shown. The outer container 2 and the inner container 3 having a thickness of 2 mm were injection-molded with polyethylene terephthalate (manufactured by Sanleng Chemical Co., Ltd.). At this time, the width of the space between the outer and inner containers 2 and 3 was 5 mm. Further, on the outer surface of the inner container 3 and the inner surface of the outer container 2, such as Figure 5 The radially shallow grooves 11 are shown, thereby minimizing flow resistance when evacuated and filled with a low thermal conductivity gas.

[0088] Polyethylene is used as insulating material 5 . It was moulded to a thickness of 5mm and had a connected lattice structure.

[0089] The heat insulating material 5 is provided between the outer container 2 and the inner container 3, and the outer container edge portion 6 and the inner container edge portion 7 are connected integrally by a vibration welding machine.

example 2

[0094] as figure 1 In another aspect of the illustrated insulated container 1, an outer container 2 and an inner container 3 are molded using multi-colored plastics to make an insulated container in which the inner and outer layers are made of different types of synthetic resins.

[0095] The outer container 2 and the inner container 3 were made by integral two-color molding, and the atmospheric side of the outer container 2 was a 1.5 mm thick cyclopolyolefin (trade name: APEL, manufactured by Mitsui Chemical Co., Ltd.), and the heat insulating layer side was 1.5mm thick polyketone (manufactured by Shell Japan Ltd.). At this time, the thickness of the space between the outer container 2 and the inner container 3 was 5 mm. Also, on the outer surface of the inner container 3 and the inner surface of the outer container 2, such as Figure 5 The radially shallow grooves 11 are shown to minimize flow resistance when evacuating and filling with a low thermal conductivity gas.

Abstract

The invention relates to a thermally insulated synthetic resin container (1, 31, 61, 81), a thermally insulated synthetic resin lid (21, 51) , and a manufacturing method therefor. The thermally insulated synthetic resin container comprises a thermoinsulating layer (4, 43, 65, 92) comprising a thermoinsulation material (5, 34, 64, 84) in which is retained at least one low thermoconductive gas, disposed in a space between a synthetic resin inner container (3, 33, 63, 83) and outer container (2, 32, 62, 82). The thermally insulated synthetic resin lid similarly comprises a thermoinsulating layer comprising the thermoinsulation material (24, 54), disposed between a synthetic resin lower lid (22, 52) and upper lid (23, 53). The synthetic resin thermally insulated container and lid can be manufactured more easily than conventional thermally insulated metal containers, at lower manufacturing cost.

Description

technical field [0001] The invention relates to a heat insulating container and a heat insulating cover, such as a vacuum bottle, a freezer box, an ice box, and a heat insulating cup heat insulating lunch box. The present invention particularly relates to a heat-insulating synthetic resin container and a heat-insulating synthetic resin cover. A double-wall container or a four-wall container is provided with a heat insulating layer, and a heat insulating material in the layer is filled with a heat insulating layer. Gas with low thermal conductivity. [0002] This application is based on Japanese Patent Application No. Hei 10-53978, the contents of which are incorporated herein by reference. Background technique [0003] Heretofore, as a high-insulation-capacity heat-insulating container, a vacuum heat-insulating metal container is known, which has an inner container and an outer container made of metal (usually stainless steel), and a space between the inner container and th...
