Description

Paper-base composite structure of beverage bottle

Technical Field

The utility model relates to a structure of a beverage container, in particular to a paper-based composite structure of a beverage bottle.

Background

Most of the most widely used beverage containers in the market at present are plastic bottles (or PET bottles), the raw material for producing the traditional plastic bottles is mainly Polyethylene terephthalate (PET), and since PET bottles are produced and used in large quantities worldwide, but PET bottles cannot be naturally degraded, the problem of how to treat the garbage in PET bottles becomes a large environmental protection subject in all countries at present.

In order to solve the environmental problem caused by plastic bottles, containers made of naturally degradable environmental friendly materials are proposed and put into mass production. For example, the known tetra pak (also called "tetra pak") basically uses a sealed box-shaped container made of materials including paper, adhesive (PE) and aluminum foil, and the tetra pak is manufactured by printing and hot-pressing trees into thin paper rolls; the common tetra Pak has seven layers of structures, and is manufactured by using a full-line mechanical automatic production process, wherein the seven layers of structures and the production process thereof comprise: the aluminum foil layer (innermost layer) - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -. The conventional tetra Pak manufacturing process requires many steps including hot pressing and cutting, and is complicated and causes leakage if the hot pressed product is not good.

The applicant proposes a stone paper container structure in taiwan patent No. TW M565711 granted by the present applicant, which is basically made of a material having at least two layers of stone paper layers, and because the stone paper is basically made of a material in which an inorganic filler (e.g., calcium carbonate CaCO3) and a plastic are mixed, the conventional wood pulp paper is not used at all, so that the consumption of tree resources in the conventional paper industry can be reduced, and the plastic contained in the stone paper can be a biodegradable organic plastic (e.g., aliphatic or semi-aromatic polyester such as PLA, PBS, PBAT, etc.), and has a natural degradation effect, and can be recycled and reproduced, thereby completely conforming to the concept of environmental protection. Although the stone paper container structure is made of wood pulp paper which accords with the concept of environmental protection, the stone paper container still mainly uses the stone paper container to replace the traditional paper cup based on the technical problem that the structural strength of pure stone paper cannot directly replace plastics to manufacture a beverage bottle.

Based on the characteristic that wood pulp paper accords with the environmental protection concept, the applicant provides a paper-based composite structure of a beverage bottle through years of practical experience and technology, the technical problem that wood pulp paper can not directly replace plastics to manufacture the beverage bottle is solved through the special paper-based composite structure created by the paper-based composite structure, and meanwhile, the environmental protection problem caused by the traditional plastic bottle and the paper container is solved.
