Abstract
The utility model provides a vacuum flask, which mainly aims to solve the problem that a refill is easy to be broken when the prior vacuum flask withstands impact. The utility model comprises an outer shell, a refill arranged in the outer shell, a support base and a handle fixed on the outer shell. The utility model is characterized in that the outside of the refill is provided with a hard foam layer; the hard foam layer closely matches with the outer shell and the refill; the upper end is covered on the inner side of the outer shell; the bottom is provided with a circular opening which is smaller than the inner diameter of the support base; the support base is arranged below the hard foam layer; the hard foam layer has a certain damping function when withstanding impact. Therefore, the refill is not easy to be broken. And the plastic is not easy to disperse heat; the insulation effects of the vacuum flask are better.
Description
Affiliated technical field
The utility model relates to a kind of container of daily insulation usefulness, particularly a kind of vacuum flask of containing hot water.
Technical background
The thermos bottle that occurs in the prior art, owing to only be provided with a rigid plastics supporting seat in the bottom between its shell and the glass liner, when vacuum flask withstood shocks, glass refills wherein was broken easily, makes bad and also can damage the person.
Summary of the invention
For overcoming the shortcoming that above-mentioned prior art exists, the purpose of this utility model provides the vacuum flask that a kind of glass liner is difficult for fragmentation and high insulating effect.
The main technical schemes that the utility model solves its technical problem is this kind vacuum flask, comprise shell, place glass liner, the supporting seat within the shell and be fixed on handle on the shell, it is characterized in that: the outside at glass liner is provided with layer hard foam, this layer hard foam and shell and glass liner closely cooperate, its upper end is wrapped in the inboard of case body, the bottom is provided with a circular open less than the supporting seat internal diameter, and supporting seat is positioned at the below of layer hard foam.
The beneficial effects of the utility model are: owing to be provided with one deck rigid foam between shell and glass liner, when vacuum flask bears certain impact, lining layer hard foam betwixt has cushioning effect, and glass liner can be not broken easily, uses safer.And the difficult heat radiation of foamed plastics, the heat insulation effect of vacuum flask will be better.
Description of drawings
Be elaborated below in conjunction with accompanying drawing.
Accompanying drawing is a main cutaway view of the present utility model.
Among the figure, 1-shell, 2-glass liner, 3-rigid foam, 4-handle, 5-supporting seat.
Specific embodiment
In the accompanying drawings; this kind vacuum flask; comprise shell (1), place the glass liner (2) within the shell; the outside of glass liner (2) is provided with layer hard foam (3); the upper end of this layer hard foam is wrapped in the inboard of shell (1); its bottom be provided with one less than the circular open of supporting seat (5) internal diameter with protection glass liner vacuum port, glass liner (2) is seated on the supporting seat (5) together with the rigid foam of its underpart, handle (4) is fixed in a side of shell.Layer hard foam and shell and glass liner closely cooperate.This layer hard foam can adopt polyurethane foam plastics.Rigid foam has cushioning effect when withstanding shocks, make fragmentation easily of glass liner; And the difficult heat radiation of rigid foam, the heat insulation effect of vacuum flask will be better.
