Abstract

The utility model relates to a thermos bottle (cup), which is composed of an inner liner and a housing. The utility model is characterized in that the inner liner has a single layer structure, and the external wall of the inner liner is tightly sheathed with an outer liner. The inner liner is connected with the outer liner to form an integrative structure in the housing. The utility model has the advantages of simplified production process and reduced cost, and the anticrash and non-broken performances can be improved by using the utility model.

Description

Thermos bottle (cup)

The utility model relates to a kind of vacuum flask and thermos cup.

Existing vacuum flask (cup) all adopts double-layer vacuum insulation glass refills structure, and the anti-heat-conduction principle of confined space vacuum carries out the insulation of water in bottle (cup) courage in the anti-heat of the inside and outside courage minute surface of its utilization, radiation theory and the interior wall of outer container.The said structure production technology is complicated, and cost is higher, and it be glassware, and is easily broken, and its bottom is gone up and given prominence to sharp mouth and also damage easily and make insulation failure.

The purpose of this utility model is exactly in order to address the above problem, and provides a kind of simple in structure, the vacuum flask that intensity is high (cup).

Technical solution of the present utility model:

A kind of vacuum flask (cup), it is made up of inner bag 1 and shell 2, it is characterized in that inner bag 1 is the individual layer inner-tube structure, and the outer wall of inner bag 1 closely is set with the outer courage 3 of the insulation of being made by insulation material, and they connect as one and place in the shell 2.

The utility model is changed the double-deck bladder structure of traditional vacuum insulation; and adopt inner bag to add the structure of heat-insulation layer; production technology is simplified greatly; manufacturing cost reduces, and because heat-insulation layer adopts insulation material to make, it had both had heat insulation function; the function that has simultaneously the protection inner bag again; crashworthiness, crash resistance improve greatly, and have saved the outstanding sharp mouth in bottle (cup) courage bottom, and heat-insulating property is more reliable.

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

As Fig. 1, individual layer inner bag 1 useable glass of the present utility model, reflectorized materials such as stainless steel are made, the characteristic that keeps traditional glass liner inwall minute surface anti-heat radiation, also can adopt pottery or hard nonpoisonous plastic material to make, being incubated outer courage 3 should adopt thermal conductivity factor to be not more than the insulation material making of 0.05W/M.K, as polystyrene foam, polyvinyl chloride foam, glass fibre etc., preferably adopt hard polyurethane foam material to make, because of it is a kind of very desirable insulation material, alternative vacuum heat-insulating layer, it is also very convenient to make the outer courage 3 of insulation with it, both can be in mould form and inner bag 1 be solidified as a whole, also can first moulding make, following two sections outer courage covers, the outer wall that is set in inner bag 1 then fuses.The outer courage 3 of insulation of the present utility model still is suitable for for existing double-layer vacuum heat-insulating internal container, and it shields to double-layer inner containers, and in the time of can not being incubated after the sharp-tongued evil idea of outstanding point as if double-layer vacuum inner bag bottom, the outer courage 3 of suit insulation of the present utility model still can normally use.

Claims

1, a kind of vacuum flask (cup), it is made up of inner bag 1 and shell 2, it is characterized in that inner bag 1 is the individual layer inner-tube structure, and the outer wall of inner bag 1 closely is set with the outer courage 3 of the insulation of being made by insulation material, and they connect as one and place in the shell 2.

2,, it is characterized in that individual layer inner bag 1 useable glass, stainless steel reflectorized material make by the described vacuum flask of claim 1 (cup).

3,, it is characterized in that individual layer inner bag 1 is gone back useful ceramics or the hard nonpoisonous plastic material is made by the described vacuum flask of claim 1 (cup).

4,, it is characterized in that being incubated outer courage 3 and should adopt thermal conductivity factor to be not more than the insulation material making of 0.05W/M.K by the described vacuum flask of claim 1 (cup).
