Abstract

The utility model discloses a shockproof thermos, which comprises a casing, a handle arranged on the casing, an inner liner and a bottle cover, wherein, a shockproof insulating layer which is matched with the inner liner is arranged between the casing and the inner liner and tightly matched with the inner cavity wall of the casing. The utility model combines three functions of anti-shock, anti-scald and good heat insulation, and has the advantages of simple manufacture technology, simple and reliable use.

Description

A kind of explosion-proof vacuum flask

Technical field

The utility model relates to a kind of explosion-proof vacuum flask.

Background technology

At present, the vacuum flask of selling on the market is more, generally comprise shell, inner bag, bottle cover etc., because shell and inner bag only contact with each other at vacuum flask bottleneck position and bottom, cause heat insulation effect relatively poor, if because of in a single day reasons such as hand-held shakiness cause vacuum flask to be fallen down, very easily broken so that scald the user, bring great inconvenience to daily life.

Summary of the invention

For solving the problems of the technologies described above, the utility model provides a kind of and has anti-ly fallen, impact resistance, the explosion-proof vacuum flask of good heat insulation effect.

The technical scheme that its technical problem that solves the utility model adopts is: it comprises shell, be located at handle, inner bag and bottle cover on the shell, be provided with between described shell and the inner bag one and inner bag is suitable and with the close-fitting anti-shock, thermal insulating layer of shell inner cavity wall.

Described handle is provided with boss, and the boss below is close to the boss place and is provided with anti-skidding stupefied.

Institute's anti-shock, thermal insulating layer is that polyurethane foam plastics constitutes.

Institute's anti-shock, thermal insulating layer is that polystyrene foam plastics constitutes.

Adopt above technical scheme, heat-insulation layer is connected together shell and inner bag well, has explosion-proof, the anti-scald heat insulation function that injures; The handle place is provided with boss, and it is anti-skidding stupefied that boss below is provided with, and makes hand-held more stablely, and the utility model technology is simple, and cost of manufacture is low, and inner bag is difficult for broken and carries easily, is suitable for very extensive.
