CN2164244Y - Thermal insulating container with plastic inner liner - Google Patents

Abstract

The utility model relates to a thermal insulating container with a plastic inner liner and the film coating. The transparent inner liner is made of plastic. The outer wall of inner liner is coated with metal film. The exterior of the inner liner is provided with a shell body. The inner liner and the shell body are provided with a plastic foaming layer. The utility model is made into various products of cups, kettles, boxes, bottles, etc., as required. The metal film of the exterior of the inner liner, such as aluminum or mercury, etc., generates the heat radiation. The foaming layer further strengthens the thermal insulation effect. The heat dissipation of the related substance of the inner liner is reduced.

Description

Thermal insulating container with plastic inner liner

The utility model belongs to cool-bag, relates generally to daily living articles such as cup, kettle, bottle, box.

The existing cool-bag of filming, as thermos bottle etc., its inner bag adopts glassware, the glass courage external packing housing of filming.The cool-bag that has occurred various plastics inner bags at present, it is mainly constructed is to inject foaming layer between inner bag and housing, is incubated by foaming layer, and the defective of its existence is that thermal loss is fast, and heat insulation effect is poor.

The purpose of this utility model provide a kind of outside the plastics inner bag cool-bag of coated with metal film.

The film design of cool-bag of the utility model plastics inner bag is: formed by injecting foaming layer between inner bag, housing and the inner bag, scribble metal film at the outer wall of plastics inner bag.

The plastics inner bag of the present utility model cool-bag of filming, so-called plastics inner bag is to make transparent inner bag by makrolon material, coats aluminium alloy film at transparent Merlon inner bladder outer wall.

The utility model discloses and a kind ofly make transparent inner bag with Merlon, coated with metal film outside the tank, compared with the prior art, metal film produces radiation to heat, and the material heat is lost in the inner bag that slows down, and has high insulating effect, as make various cups or lunch box etc., practicality is wide.

Fig. 1 be the utility model plastics inner bag film make the cup the special case schematic diagram.

Below in conjunction with Fig. 1 embodiment of the present utility model is elaborated.

The utility model selects for use heatproof and the good plastic raw materials of intensity to make inner bag 3, inner bag requires transparent, as adopt makrolon material, use heat resisting temperature can reach 120 ℃, at transparent inner bladder outer wall coated with metal film 4, vacuum available is filmed, and metal film can have good heat radiation effect with aluminium or mercury, make the material in the courage reach the insulation purpose, inner bag overcoat upper shell 5, housing also can be made of metal generally by injection-moulding plastic, in housing and inner bag, inject foaming layer 6, foaming layer plays further insulation, therefore by the inner bag that scribbles metal film, foaming layer, three layers of composition of housing are made cup as required, kettle, box, various products such as bottle.Cup covers 1 and interior pad 2 among Fig. 1, can be held by bottom 7 in the bottom.

Claims (2)

1, the plastics inner bag cool-bag of filming is formed by injecting foaming layer between inner bag, housing and inner bag and the housing, it is characterized in that the outer wall of plastics inner bag scribbles metal film.

2, cool-bag as claimed in claim 1 is characterized in that plastics are that makrolon material is made transparent inner bag, coat aluminium alloy film at transparent Merlon inner bladder outer wall.
