CN201691752U - Safe thermos bottle - Google Patents

Abstract

The utility model relates to a safe thermos bottle comprising a shell (1), a bottom cover (2) and a bottle plug (5), wherein the bottom cover (2) is arranged at the bottom of the shell (1); and the shell (1) is internally provided with a bottle liner. The safe thermos bottle is characterized in that the bottle liner (3) arranged inside the shell (1) is a single-layer plastic liner; and thermal insulation material is filled in a clearance between the shell (1) and the bottle liner (3) to form a thermal insulation layer (4). The safe thermos bottle has simple and the practical structure, not only ensures thermal insulation effect, but also eliminates the potential safety hazard caused by glass fragments after the current bottle liner is broken; and the safe thermos bottle can not be broken easily and has long service life.

Description

Safe thermos flask

Technical field

The utility model relates to a kind of thermos flask structure, belongs to technical field of living goods.

Background technology

More present specific safety departments; the specific group of putting in prison as punishment office of government; in this special environment; personal safety is first important elements; in order to ensure putting in prison being perfectly safe of colony; all there is not potential safety hazard in all article that they are contacted, simultaneously can't be with their inconvenience in life.

Thermos bottle inner bag in the market all is double-layer heat insulation courages that glass is made, and its glass fragment of smashing back formation has potential safety hazard, not only is not suitable for specific safety department and uses, and average family also the thing that thermos flask is toppled over the inner bag fragmentation occurs through regular meeting when using.

Summary of the invention

The purpose of this utility model is exactly at above-mentioned the deficiencies in the prior art, provide a kind of simple and practical, do not influence heat insulation effect, be difficult for broken, the safe thermos flask of long service life.

The technical solution adopted in the utility model is as follows:

A kind of safe thermos flask comprises shell, bottom and bottle stopper, and bottom is installed in outer casing bottom, glass liner is housed in the shell, it is characterized in that the described glass liner that is installed in the shell is the monolayer plastic courage, the interlayer space between shell and glass liner is filled with insulation material, forms heat-insulation layer.

The insulation material of described heat-insulation layer is cotton-wool or foamed plastics.

Described glass liner upper port is threaded with the shell upper end.

The beneficial effects of the utility model have:

Simple and practical, both guaranteed heat insulation effect, also eliminated the potential safety hazard of glass fragment after the present glass liner fragmentation, be difficult for broken, long service life.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

The specific embodiment

The utility model is further described below in conjunction with accompanying drawing:

As shown in Figure 1, the utility model is made up of shell 1, bottom 2, glass liner 3, heat-insulation layer 4 and bottle stopper more than 5 parts, and bottom 2 is installed in shell 1 bottom, and glass liner 3 is installed in the shell 1.For guaranteeing safety, glass liner 3 is the monolayer plastic courage, and its material is that nontoxic, tasteless, resistant to elevated temperatures high-quality plastics is made.2 of shell 1 and bottoms can use common plastics to make.Because what glass liner 3 adopted is the monolayer plastic courage, for guaranteeing the heat insulation effect of thermos flask, insulation material is filled up in the interlayer space between shell 1 and glass liner 3, forms heat-insulation layer 4.The insulation material of heat-insulation layer 4 is heat insulating material formed making of high-quality such as good cotton-wool of thermal property or foamed plastics.

Screw thread on the utility model shell 1 and glass liner 3 two-port connects, and tightens the back mutually and fills up with insulation material in the space of centre, bottom 2 is installed on the screw thread on shell 1 base again, at last bottle stopper 5 is contained in the effect that can play insulation in glass liner 3 ports.Bottle stopper 5 of the present utility model adopts at present existing ordinary bottle plug to get final product.

Other undeclared part that the utility model relates to is same as the prior art.

Claims (3)

1. safe thermos flask, comprise shell (1), bottom (2) and bottle stopper (5), bottom (2) is installed in shell (1) bottom, shell is equipped with glass liner in (1), it is characterized in that the described glass liner (3) that is installed in the shell (1) is the monolayer plastic courage, interlayer space between shell (1) and glass liner (3) is filled with insulation material, forms heat-insulation layer (4).

2. safe thermos flask according to claim 1, the insulation material that it is characterized in that described heat-insulation layer (4) is cotton-wool or foamed plastics.

3. safe thermos flask according to claim 1 and 2 is characterized in that described glass liner (3) upper port is threaded with shell (1) upper end.
