1. Field of the Invention

The invention relates to the technical field of thermal insulation package, and in particular, to an airtight thermal insulation package with a large opening therein.

2. Description of the Related Art

The traditional food storage packages do not have the heating function. The thermal insulation package on the market is a package that can hold drinks or food and keep the temperature and freshness thereof, which adopts the hot-melt seamless bonding technology and has a long thermal insulation time. It is a special package with temporary thermal insulation effect, which can keep cold or warm. The package that can keep cold is generally called cold insulation package, which can be used as the mobile refrigerator to keep the freshness of iced drinks, fruits, breast milk, tea, seafood and other foods, and can also be used for the refrigerated transportation of medicines, vaccines and other products; thermal insulation is generally used for food and lunch heat preservation, and for the delivery of food of restaurant, etc. For example, it can be used for children to bring lunch to school, which not only makes them enjoy fresh or warm food at any time, but also ensures the food sanitary and healthy. At present, the common insulation package material on the market is the non-woven fabric plus aluminum film pearl cotton, which can provide good thermal insulation effect; the product can be folded for convenient carrying and the design is portable, light and fashionable. The food can be kept warm and fresh for a long time. It is easy to use and suitable for outdoor picnics and daily life, and is therefore largely used.

However, the function of traditional thermal insulation packages is single, and the opening therein is small, which is inconvenient for accessing the food container; therefore, it is easy to cause the dumping of food container during the process of accessing it, which causes the soup to leak inside the thermal insulation package body, and it is difficult to clean. In addition, for the prior thermal insulation package, the food container and tableware are placed inside the package body, which is not only inconvenient to access, but also causes bad eating sanitary habits. Therefore, there is a need for an airtight thermal insulation package with a large opening therein to improve the above problems.

Preferably, the tableware box is provided with two groups in total, both of which are movably arranged at the two inner sides of the base, and the base surface center of the tableware box is provided with a handle.

Preferably, the top of the outer pocket is provided with a zipper.

Preferably, the left iron wire frame and the right iron wire frame are symmetrically arranged inside the zipper enclosure.

Preferably, the inner wall of the thermal insulation package body is provided with a bonding belt stuck with the velcro.

Preferably, the thermal insulation package body is a seamless airtight thermal insulation package made by hot pressing method with TPU material.

Compared with the prior technology, the invention has the advantageous effects that:

1. When the zipper of the zipper enclosure with the iron wire frame is opened, the left iron wire frame and the right iron wire frame in the package opening can be oppositely unfolded to the body of the thermal insulation package, and the effect of a large opening is achieved.

2. Through the manufacturing process of adopting zipper enclosure and side tab, two sides of the zipper edge of zipper enclosure extend out of the package body and fit on two sides of the side patch top, which achieves the purpose that the zipper is extended out of the package body to a large opening.

3. Through the process that the zipper patch of the inner lining extends out and fits on two sides of the zipper edge of zipper enclosure to be aligned with the side patch top, and two sides of the zipper tail are closed by hot pressing method to achieve the effect of sealing the zipper edge.

4. The provided tableware box offers the convenience that the food container and the tableware are placed respectively. At the same time, when two sets of tableware are needed, they can be placed respectively through two groups of tableware box, so that each of them has independent storage space, thereby to achieve the purpose of paying attention to the eating sanitary habits.

5. The overall structure of the device is simple and the sealing effect is good; the effect of a large opening is achieved and it has certain promotion value.

PREFERRED EMBODIMENTS OF THE INVENTION

The technical solutions in the embodiments of the invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the invention. It is obvious that the described embodiments are only parts of the embodiments of the invention, not all of the embodiments. All other embodiments based on the embodiments of the invention made by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the invention.

With reference toFIG. 1-4, the invention provides a technical solution:

An airtight thermal insulation package with a large opening therein, comprising a base1, a tableware2, a thermal insulation package body3, a zipper enclosure8, an iron wire frame10and a strap16, wherein the side of the base1is provided with the tableware box2and the tableware box2is provided with two groups in total, both of which are movably arranged at the two inner sides of the base1, and the base surface center of the tableware box2is provided with a handle.
