Barrier bottle and manufacturing method thereof

Abstract

The invention relates to a barrier bottle and a manufacturing method thereof. The barrier bottle comprises a bottle body, a bottle opening and a bottle bottom, an accommodating cavity for accommodating contents is formed in the bottle body, the bottle opening is formed in the top of the bottle body and communicates with the accommodating cavity, the bottle bottom is arranged at the bottom of the bottle body, a blocking interlayer capable of blocking light, gas and water is arranged in the bottle bottom in the extending direction of the bottle bottom. According to the barrier bottle, the technical problem that the contents cannot be fully protected due to the fact that a blocking hole is formed in the bottom of the PET bottle body is solved.

Description

technical field [0001] The present invention relates to a bottle type, further, to a barrier bottle and a manufacturing method thereof, in particular to a barrier bottle with a barrier layer arranged at the bottom of the bottle body and a manufacturing method thereof. Background technique [0002] In recent years, with the continuous improvement of residents' living conditions and consumption levels, beverage products such as dairy products, dairy beverages, compound fruit juices, and fruit and vegetable juices have developed rapidly. Susceptible to spoilage, resulting in loss of taste or efficacy. At present, the packaging used for this type of beverage products mostly uses composite film paper cans with barrier properties, PET (polyethylene terephthalate) bottles, PE (polyethylene) bottles, glass bottles or metal cans, etc., among which PET bottles In terms of plastic packaging, most of the methods of adding barriers to PET raw materials, such as adding light barriers and...

Problems solved by technology

[0003] However, with the implementation and promotion of the European plastic restriction order, my country's PET industry has also introduced requirements for sustainable development, that is, to realize the recycling and reuse of PET raw materials, and the current PET bottle type is made by adding a barrier agent , leading to the inability to recycle the materials produced by PET bottles, resulting in the waste of PET materials after drinking, and hindering the further development of PET bottles

[0004] In the prior art, although some companies take barrier measures for PET bottles, they are limited to the barrier of the bottle body, and the bottom of the bottle is often ignored as a part of the PET bottle body. Therefore, the existing PET bottle body has a great barrier Vulnerabilities lead to deterioration of the content due to inability to be completely protected, and the purpose of extending the shelf life of the product cannot really be achieved

[0005] In view of the barrier loopholes in the bottom of the PET bottle in the related art, which cannot fully protect the contents, no effective solution has been proposed yet
