Abstract

The utility model discloses a safe thermos flask, include: the inner container and the shell are sleeved at intervals, the opening of the inner container and the shell is overlapped, connected and sealed, and the opening is plugged by a rubber plug; the plastic sealing bag is sleeved outside the inner container, and the opening of the plastic sealing bag is hermetically connected with the opening of the inner container; the sponge damping ring is arranged between the inner container and the shell, and the sponge damping ring is fixed on the inner wall of the shell and compresses the plastic sealing bag on the outer wall of the inner container. This device can effectively slow down vibrations, reduces the broken probability of kettle, and when the inner bag broke, the plastic sealing bag can effectively prevent hot water spill to alleviate broken inner bag through the layer that absorbs water and to the impact of plastic sealing bag, cause the damage to it.

Description

Safety thermos bottle

Technical Field

The utility model relates to a daily article, in particular to a safe thermos bottle.

Background

The thermos bottle in the prior art is fragile and easy to cause scald after being broken, and the stainless steel thermos bottle has poor heat insulation performance, high manufacturing cost and good quality, and the stainless steel thermos bottle without harmful substances is too expensive.

SUMMERY OF THE UTILITY MODEL

Utility model purpose: in order to overcome the defects of the background art, the utility model discloses a safe thermos bottle.

The technical scheme is as follows: the utility model discloses a safe thermos flask, include:

the inner container and the shell are sleeved at intervals, the opening of the inner container and the shell is overlapped, connected and sealed, and the opening is plugged by a rubber plug;

the plastic sealing bag is sleeved outside the inner container, and the opening of the plastic sealing bag is hermetically connected with the opening of the inner container;

the sponge damping ring is arranged between the inner container and the shell, and the sponge damping ring is fixed on the inner wall of the shell and compresses the plastic sealing bag on the outer wall of the inner container.

Furthermore, the sponge damping ring is arranged on the inner wall of the shell at intervals.

Further, the outer wall of the inner container is coated with a water absorbing layer.

Further, the water absorption layer is made of high water absorption resin material.

Further, the water absorption layer is spirally coated on the outer wall of the inner container for multiple circles.

Has the advantages that: compared with the prior art, the utility model has the advantages that: this device can effectively slow down vibrations, reduces the broken probability of kettle, and when the inner bag broke, the plastic sealing bag can effectively prevent hot water spill to alleviate broken inner bag through the layer that absorbs water and to the impact of plastic sealing bag, cause the damage to it.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Detailed Description

The technical solution of the present invention will be further explained with reference to the accompanying drawings and examples.

The safety thermos bottle as shown in fig. 1 includes:

the inner container 1 and the shell 2 are sleeved at intervals, the opening of the inner container 1 and the shell 2 is overlapped, connected and sealed, and the opening is plugged by the rubber plug 3;

the plastic sealing bag 4 is sleeved outside the inner container 1, and the opening of the plastic sealing bag 4 is hermetically connected with the opening of the inner container 1 and can be directly adhered by glue;

the sponge damping ring 5 is arranged between the inner container 1 and the shell 2, the sponge damping ring 5 is fixed on the inner wall of the shell 2, and the plastic sealing bag 4 is tightly pressed on the outer wall of the inner container 1. The middle part and the lower part of the inner wall of the shell 2 are respectively provided with one sponge damping ring 5.

In order to relieve the impact on the plastic sealing bag 4 when the inner container 1 is broken and absorb water properly, the outer wall of the inner container 1 is coated with a water absorbing layer 6. The water absorbing layer 6 is made of high water absorbing resin material, and the outer wall of the inner container 1 is coated with a plurality of circles in a spiral mode.

According to the first defense line of the safety thermos bottle, the sponge damping ring 5 plays a damping role, so that the probability of breakage of the bottle is reduced; the plastic sealing bag 4 can receive impact when the inner container is broken to hold water and prevent scalding; and the third line of defense, the water absorption layer 6 can buffer the broken impact of the liner, reduce the impact born by the bag, absorb moisture after the bag is broken and prevent scalding caused by the splashing of the scalding water.
