Description

Inflatable heat preservation/cold pack

Technical Field

The utility model belongs to the technical field of heat preservation/cold package technique and specifically relates to an aerify heat preservation/cold package.

Background

The heat-insulating bag is used for containing various foods and keeping the temperature and freshness of the foods, and can also be used for cold storage, such as putting in ice cubes, cold drinks and other low-temperature articles, so that the heat and cold insulation is the most basic function of the portable inflatable heat-insulating bag.

The common thermal insulation bag has two structures: one is that the material used is cloth composite aluminum foil, and the function of the aluminum foil reflecting heat is utilized to carry out heat preservation; the other is a self-inflating heat-preservation bag. The heat preservation bag using the cloth composite aluminum foil has poor heat preservation effect due to the limitation of thickness.

Detailed Description

In order to make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the drawings in the embodiments, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all the embodiments. All other embodiments obtained by a person skilled in the art without making any inventive step, based on the given embodiments, fall within the scope of protection of the present application.

In the description of the present application, it is to be understood that the terms "upper", "lower", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are only for convenience in describing the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present application.

Example one

This embodiment will be described in detail with reference to fig. 1 and 2. The inflatable heat preservation/cold bag related to the embodiment comprises a bag cover 1, a bag body 2 and a bag bottom 3. One end of the bag body 2 is connected with the bag cover 1, and the other end is connected with the bag bottom 3 to form a space for accommodating articles.

The bag body 2 comprises an inner wall layer 21 and an outer wall layer 22 with two closed ends, and the upper end and the lower end of the inner wall layer 21 and the upper end and the lower end of the outer wall layer 22 are respectively connected and closed to form a gas chamber. The bag body 2 also comprises a plurality of drawstrings 23 connected with the inner wall layer 21 and the outer wall layer 22, and the drawstrings 23 are provided with set intervals, preferably, the intervals are fixed, namely, the drawstrings are uniformly arranged.

Specifically, in the present embodiment, the inner wall layer 21, the outer wall layer 22 and the pull tape 23 are made of flexible materials. And the length of the pull tape 23 on each side wall of the bag body 2 is preferably the same between the inner wall layer 21 and the outer wall layer 22. In the height direction of the inflatable heat preservation/cold bag, the height of the drawstring 3 is preferably slightly smaller than that of the bag body 2, so that gas can easily circulate for inflation and deflation. The shape of the heat-insulating layer after inflation can be limited by the arrangement of the pull straps 3 so as to avoid irregular expansion, and the space surrounded by the outer wall layer 22 and the inner wall layer 21 after inflation can form a cylindrical heat-insulating layer with an annular section, so that the bag body 2 is surrounded to form a stable accommodating space. An inflating nozzle 24 is arranged on the bag body 2, particularly, the inflating nozzle 24 is arranged on the outer wall layer 22, so that inflation and deflation of the heat insulation layer between the inner wall layer 21 and the outer wall layer 22 can be realized.

Because the heat preservation/cold package has the inflatable heat preservation, can have better isolation with the external world, have the effect of good keep temperature, can keep having lower temperature in the heat preservation/cold package for a long time.

Specifically, in the present embodiment, the material of the inner wall layer 21, the outer wall layer 22 and the pull tape 23 is any one of TPU, PVC, EVA, TPU composite material, PVC composite material and EVA composite material.

And the draw tape 23 is bonded to the inner and

outer wall layers

21, 22 by adhesive, heat fusion, high frequency welding or ultrasonic welding.

Specifically, the ladle cover 1 and the ladle bottom 3 are preferably formed by attaching an EVA (ethylene vinyl acetate) plate, TPU (thermoplastic polyurethane), PVC (polyvinyl chloride) composite or PVC composite or cloth. The bag cover 1 and the bag body 2 are detachably connected. Specifically, the bag cover 1 and the bag body 2 are partially or completely connected through a zipper 4.

Example two

The difference between the inflatable insulation/cold pack related to the present embodiment and the first embodiment is that in the present embodiment, a filler is disposed in a space enclosed by the drawstring 23, the inner wall layer 21 and the outer wall layer 22, the filler is preferably an insulation material to improve an insulation effect, the filler is further preferably a flexible material to facilitate compression and storage, specifically, the filler is preferably insulation cotton, and the insulation cotton is preferably fixedly connected to the inner wall layer and the outer wall layer. The heat preservation cotton can make the inflatable heat preservation/cold bag related to this embodiment, have better heat preservation effect.

The foregoing has described in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations can be devised by those skilled in the art in light of the present teachings without departing from the inventive concepts. Therefore, the technical solutions that can be obtained by a person skilled in the art through logic analysis, reasoning or limited experiments based on the prior art according to the concepts of the present invention should be within the scope of protection defined by the claims.
