Heat-insulating container

Technical Field

The utility model relates to a container technical field especially relates to a heat preservation container.

Background

The double-layer inner container of the existing heat-insulating container can generate a corrosion phenomenon on the cup mouth when a salt spray test is carried out, and the cup mouth can not reach the national standard of a vacuum cup. The invention discloses a vacuum cup with a titanium composite inner container and a manufacturing process thereof, as the Chinese invention patent application (patent number: 202010068652.4) discloses a vacuum cup with a titanium composite inner container and a manufacturing process thereof, wherein the vacuum cup comprises an inner container body, the inner container body comprises a first inner container layer and a second inner container layer, the first inner container layer and the second inner container layer are concentrically arranged, the first inner container layer is made of stainless steel materials or copper materials or iron materials or aluminum materials, the second inner container layer is made of titanium materials, the lower end of the inner container body is provided with a first bottom layer and a second bottom layer, the first bottom layer is made of stainless steel materials, the second bottom layer is made of titanium materials, the first bottom layer is fixedly connected with the lower end part of the first inner container layer, and the second bottom layer is fixedly connected with the lower end part of the second inner container layer. The inner container body opening part in the patent adopts mechanical spinning for the double-layer material of the inner titanium and the outer steel to realize mechanical bonding of two layers of metal, and the structure has certain practicability but certain defects, and after all, the tight sealing of the two metal materials of the cup mouth is not realized. Because the outer liner of the stainless steel can generate oxides due to high temperature generated when the shell is welded with the liner steel layer, the oxides can emerge from a gap at the opening of the liner during a subsequent salt spray test, and the phenomenon of corrosion can occur. Such staining is unacceptable for products intended for consumer use.

The utility model discloses owing to adopted above technical scheme, have apparent technological effect:

1. the upper end of the inner liner is turned outwards to form a turned edge, so that a gap between the outer liner and the inner liner on the upper end surface of the inner liner is eliminated, and the phenomenon that the oxide between the outer liner and the inner liner corrodes the mouth of the inner liner is effectively avoided.

2. The lower end face of the flanging and the upper end face of the outer liner are inclined to form inclined planes, when the flanging is tightly pressed with the outer liner, the flanging and the outer liner are guaranteed to be in a rigid sealing state, and the sealing performance between the flanging and the outer liner is improved.

3. Because the upper end of the inner liner forms an arc-shaped opening through the flanging, the inner liner made of titanium material is directly contacted with a user during use, the use sanitation is improved, and meanwhile, the phenomenon that the mouth part of the inner liner cuts a nozzle during use is also avoided.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples.

Example 1

A heat preservation container, as shown in fig. 1 to 4, comprises a shell 1 and an inner container 2 arranged in the shell 1, wherein the inner container 2 comprises an outer inner container 3 and an inner container 4, the upper end of the inner container 4 is provided with a flanging 5 which turns outwards, the flanging 5 extends from top to bottom, and the lower end of the flanging 5 is connected with the upper end of the outer inner container 3 in a sealing manner. The upper end oral area of inlayer inner bag 4 outwards overturns and forms turn-ups 5, eliminates the clearance between outer inner bag 3 and the inlayer inner bag 4 on the inner bag 2 up end, avoids the upper end oral area of inner bag 2 to take place the corrosion when doing the salt spray realization, influences the use of inner bag 2. The upper end of the inner container 2 is an arc-shaped opening 8, the arc-shaped opening 8 is formed by outwards turning the inner container 2, and the inner container 4, the arc-shaped opening 8 and the turned edge 5 are of an integrated structure. The arc-shaped opening 8 is a transition arc, and two ends of the arc-shaped opening 8 are respectively connected with the upper end of the inner liner 4 and the upper end of the turned-over edge 5. The upper end of the inner liner 4 is overturned to form an arc-shaped opening 8 at the upper end opening part of the inner liner 4, so that the phenomenon of cutting torch generation during use is avoided, and the use experience of the heat preservation container is improved.

The lower end surface 6 of the flanging 5 and the upper end surface 7 of the outer-layer inner container 3 are both inclined surfaces. The lower end surface 6 of the flanging 5 and the upper end surface 7 of the outer-layer liner 3 are both gradually inclined downwards from outside to inside. The lower end face of the flanging 5 is attached to the upper end face of the outer-layer inner container 3, so that when the flanging 5 is tightly pressed against the upper end of the outer-layer inner container 3, the sealing performance of connection between the flanging 5 and the outer-layer inner container 3 is improved.

The flange 5 is attached to the outer side wall of the upper end of the inner liner 4. No gap is left between the flange 5 and the inner liner 4, so that the phenomenon that air or impurities enter between the flange 5 and the inner liner 4 to cause oxidation and rust on the opening part of the inner liner 2 is avoided. The upper end of the outer shell 1 is welded with the outer side wall of the outer layer inner container 3.

The inner liner 4 is made of titanium material, and the outer liner 3 is made of metal material except titanium material. The outer liner 3 is made of copper material, stainless steel material or aluminum material. The outer shell 1 and the outer liner 3 are made of the same material.
