Abstract

The utility model discloses a thermos bottle, which is characterized in that the liner of the thermos bottle is formed by that assemblies formed by that sheet metal are punched are welded; an interlayer is vacuum; enamel glaze protective layers are coated on the external and internal surfaces of the liner of the thermos bottle, and thus the liner of the thermos bottle becomes a bottle body which can be directly used. The utility model which uneasy to be damaged has the advantages of simple and handy structure, beauty, etc., and is suitable for being served as the thermos bottle or a container storing hot and cold beverages in families.

Description

Thermos with metal enamel liner

The utility model relates to a kind of vacuum flask, particularly a kind of metallic enamel glass liner vacuum flask.

The vacuum flask of people's use now mainly is made up of glass liner, bottle shell, bottle stopper, bottle cap and handle.Because the glass liner of this vacuum flask is to make with glass always; broken easily in manufacturing, accumulating, sale and use; and in glass liner outside a shell with metal or plastics manufacturing must be set also and be protected and to use; seem complicated on the structure; adding the glass refills internal layer also must be silver-plated; therefore, resulting cost is also than higher, but also expends many precious metals.

The purpose of this utility model is to overcome the deficiency of existing vacuum flask, provides a kind of not fragile, and vacuum flask simple in structure newly designs.

Introduce structure of the present utility model below in conjunction with accompanying drawing:

Fig. 1 is the front view of the utility model concrete structure.

Among the figure, (1) is that bottle cap, (2) are glass liner for bottle stopper, (3).The body of glass liner of the present utility model (3) is to be welded by the shell body (3a) of metal, inner housing (3b) and bottom (3c); On bottom (3c), be provided with the mouth of bleeding (3d); Surfaces externally and internally at glass liner (3) body is covered with one deck vitreous enamel (3e).

Realization of the present utility model is to adopt industrial mature punching press, and welding and enamel technology are processed and made.The processing of shell body (3a) and inner housing (3b) can divide 2-4 section punch forming part to weld together and constitute.In order to extract the air in glass liner (3) interlayer out, and seal simultaneously, make and form vacuum in the glass liner interlayer, the mouth of bleeding (3d) of tubulose can be connected the vavuum pump flexible pipe, flatten with the punch press mouth (3d) of will bleeding immediately after deflating, then be welded together with seam welder mouth (3d) flat part of will bleeding, take off the vavuum pump flexible pipe then, just can in finishing mouth (3d) end of bleeding again.Shell body (3a), inner housing (3b) and bottom (3c) sheet metal of the most handy 0.2-0.5 are made.After the processing of whole glass liner (3) body, enamel technology routinely applies one deck vitreous enamel on glass liner (3) surface, inside and outside.The utility model can be provided with the handle and the bottle end as required.In addition, glass liner of the present utility model (3) also can be done general glass liner use.

Because glass liner of the present utility model (3) is made with sheet metal, can cancel bottle shell and directly use. And the vitreous enamel of external application both can prevent from the oxidation of metal glass liner and the heat transfer loss of minimizing metal glass liner from meeting again hygienic requirements. In addition, can also draw different patterns and color, increase the aesthetic feeling of product. Therefore, the utlity model has simple in structure lightly, fragile and not attractive and durable advantage, be suitable for the container that general family makes vacuum flask or deposit cold and hot beverage and use.

Claims
