Autoinflation packing box

Abstract

The invention relates to the technical field of a package box for instant noodles, in particular to an automatic inflation package box for the instant noodles, which comprises a box body composed of at least two film layers and food level vesicant. A hermetic inflation space is arranged between the two film layers of the box body, and the food level vesicant is placed in the inflation space and has a decomposition point between 50 and 100 DEG C. During the storage, the transportation and the preservation, the food level vesicant is not decomposed, the inflation space in the box body is deflated, and the package box for the instant noodles can be arbitrarily folded, so that the package box for the instant noodles can greatly improve the space use ratio. Compared with the prior package boxes of boxed instant noodles, the package box for the instant noodles of the invention reduces over 50 percent of space occupancy, greatly reduces the storage and the transportation costs and is convenient for the storage; during the eating of the instant noodles, the box body is filled with boiled water, the food level vesicant is automatically decomposed, and carbon dioxide is released, so that the box wall slowly erects and then the package box for the instant noodles finally becomes a hard box body with convenient use.

Description

technical field [0001] The invention relates to the technical field of instant noodle packaging boxes, in particular to an automatic inflatable instant noodle packaging box. Background technique: [0002] Packaging boxes produced by foaming materials such as PS (polystyrene) can be used in various fields. Since the packaging box cannot be folded or compressed, the packaging box takes up a lot of space, and the storage and transportation costs are high. Especially for boxed instant noodles, in order to pursue lower cost and easy to use, at present, the packaging box of boxed instant noodles is made of PS material through foaming process. Although it has the advantages of low cost and easy to use, PS It is not an environmentally friendly material. PS will decompose toxic substances at high temperatures, and PS cannot be recycled. In addition, before the boxed instant noodles are delivered to consumers, most of the space in the box is idle. The space utilization rate in the bo...
