Description

Technical Field

[0001] The utility model relates to the technical field of packaging insulation boxes, and particularly relates to an insulation box. Background Art

[0002] With the increase of people's economic income and the improvement of people's living standards, more and more people can buy the items they need, and food is a common one among them.

[0003] Food refers to various finished products and raw materials for human consumption or drinking, as well as items or foods that are both food and medicine according to tradition, but does not include items for therapeutic purposes. The types of food are rich and diverse. People can buy food ingredients to make food by themselves, and people will also order food from other places.

[0004] Many foods have certain requirements for eating temperature. People will use insulation boxes to hold and transport these foods. However, the existing insulation boxes have poor heat preservation effects and still cannot meet people's expectations.

[0005] In view of the above problems, people invented the patent number: 201920354425.0, which discloses an insulation box with good heat preservation and freshness preservation effects, including a box body and a box cover. The box body is located at the bottom, and the box cover is buckled on the upper end of the box body. The box body includes multiple insulation boards, and the end of each insulation board is a bevel structure. The ends of adjacent insulation boards are attached and locked with connectors. The box cover includes multiple box cover boards, and the end of each box cover board is a bevel structure. The ends of adjacent box cover boards are attached and locked with connectors. This design of the box body and the box cover draws on the mortise joint in woodworking structure, with good connection firmness and tightness. In this product, the bevel structures of adjacent insulation boards are attached to form the box body, and the bevel structures of adjacent box cover boards are attached to form the box cover, with good connection firmness and tightness. This product is not only applicable to baking, but also applicable to other items such as fresh food that require cold storage and freshness preservation. However, this insulation box still has the following problems: 1. In order to ensure the stability of food placement, the existing insulation boxes usually need to be protected by trays.
