A container for compounding expanded particles between inner and outer layers of film

Abstract

The invention discloses a container with foamed particles arranged between inner layer films and outer layer films. The container at least includes a bottom surface and a wall surface, wherein the lower end of the wall surface is connected to the bottom surface; each of the bottom surface and the wall surface at least include two films and a few of foamed particles; and between the two films is provided a sealed heat insulation space, and the foamed particles are connected to the heat insulation space between the two films in a loose manner. According to the invention, the weight of the container can be reduced, the two films can be supported by utilizing the foamed particles, the structural strength of the container can be improved, and meanwhile the two films can prevent gaps and water leakage. The wall surface is provided with a plurality of foldable organ structures, and the organ structures can be compressed into a smaller size in a storage and transportation process, so that the storage and the transportation cost can be greatly decreased, and the storage is convenient; and when the container is used, the organ structures can be stretched into a larger size.

Description

technical field [0001] The invention relates to the field of packaging containers, in particular to a packaging container for washing dishes or instant noodles, in particular to a packaging container that reduces weight, prevents leakage, has low cost, more stable structural strength and good thermal insulation function. A container for composite expanded particles between films. Background technique [0002] With the transformation of social patterns, more and more people are eating out. At the same time, in the case of fast, convenient and hygienic and safe dining habits, most of them will use free food stalls, night markets and other dining places in order to cope with the continuous flow of people. Wash dishes to reduce cleaning time and save labor. [0003] Generally, the commonly used disposable dishes are divided into two materials: styrofoam and paper. Among them, styrofoam is relatively cheap, but the value of recycling and reuse is not high, and it is not easy to ...

AI Technical Summary

Problems solved by technology

[0003] Generally, the commonly used disposable dishes are divided into two materials: Styrofoam and paper. Among them, Styrofoam is relatively cheap, but the value of recycling is not high, and it is not easy to decompose. Whether it is burned or buried, it will pollute the environment. ;Although paper-made disposable dishes have less pollution after use and are more convenient to handle, however, because paper-made disposable dishes need to be covered with a layer of waterproof wax or a layer of plastic film, and waterproof wax or plastic film encounters 100 ℃ High-temperature hot water will release toxic substances, coupled with the strong awareness of environmental protection in today's society, on the premise of reducing tree felling, how to effectively avoid the use of a large number of paper-made disposable dishes has become a major problem today

[0004] Most of the currently commonly used disposable bowls or instant noodles packaging bowls are made of PS (polystyrene) material through foaming technology, which is commonly known as Styrofoam, although it has low cost and high usability. The advantage of convenience, but PS is not an environmentally friendly material. PS will decompose toxic substances at high temperatures (above 80°C). Even if it can be recycled and reused, the value is not high

Although some people have used EPP (expanded polypropylene) environmental protection materials to make food containers, the cost is too high due to the low foaming ratio of the materials during production, and the market acceptance is very low, and the non-cleaning produced The bowl or the packaging bowl of instant noodles is too heavy, so it has not yet been seen on the market

[0005] In addition, PS Styrofoam bowls with insufficient thickness in the process of extrusion and foaming generally have the problems of poor heat insulation and heat preservation effects, insufficient strength, and easy cracking, which has become the primary defect that needs to be solved urgently in the prior art

[0006] Furthermore, the traditionally used packaging bowls for instant noodles generally include the volume to be poured into boiling water, and the packaging bowls are made about two to three times larger than the instant noodles inside. The packaging bowl of instant noodles cannot be folded or compressed, the packaging bowl takes up a lot of space, and the relative storage and transportation costs are also significantly increased, especially for the current instant noodles in bowls. Before the packaging bowl of instant noodles is delivered to consumers, most of the space in the packaging bowl of instant instant noodles is idle, and the space utilization rate in the packaging bowl is less than 50%. The packaging bowl occupies a large space, resulting in The packaging bowl of instant noodles is inconvenient to store, and the storage cost and transportation cost of the packaging bowl of instant noodles are also high, which has become the second defect problem to be solved urgently in the prior art
