Description

Liquid container made of natural plant material

The model relates to the structure of a beverage container, in particular to a liquid container made of natural plant material.

At present, most of the most widely used beverage containers on the market are plastic bottles (or PET bottles). The raw materials for traditional plastic bottles are mainly polyethylene terephthalate (PET). Due to large-scale manufacturing worldwide And the use of PET bottles, but PET bottles cannot be degraded naturally, so the problem of how to dispose of PET bottle garbage has become a major environmental protection issue facing all countries.

In order to solve the environmental problems caused by plastic bottles, containers made of environmentally friendly materials that can be naturally degraded have been proposed and put into mass production applications. For example, in the United States, the United Kingdom, the Netherlands, Denmark and other countries, manufacturers have proposed all paper PET bottles made by integral molding technology. This kind of bottle made entirely of paper materials and made by integral molding technology has the advantages of convenient and fast manufacturing. , But the structural strength and compressive strength are insufficient, and it is easy to break from the fragile part of the structure, so it cannot be used as a soda bottle or contain other pressured beverages or liquids (such as soda water).

The purpose of this new model is to solve the insufficient structural strength and compressive strength of the conventional paper PET bottles made by integral molding technology, as well as the environmental protection problems caused by traditional plastic bottles and paper containers.

An embodiment structure of the new all-natural plant material liquid container includes: a bottle cap, an upper bottle body, a bottle body and a bottle bottom; the top of the upper bottle body has a mouth that can be connected with the bottle cap, and the upper bottle body faces the bottom The direction of the end extends with a connecting section that can be inserted into the top of the bottle body. The cap and the upper bottle body are made of a mixture of plant fibers as the material, and are made by injection molding technology; the bottle body is made of spiral paper with a multi-layer structure. The top of the bottle body and the connecting section of the upper bottle body are glued and connected; the bottom of the bottle is a cup-shaped structure with an opening facing down. The bottom of the bottle includes a bottom surface and a side wall surrounding the bottom surface. The bottom of the bottle is stuffed into the bottle with the opening facing down. The bottom end of the bottle body and the side wall of the bottle bottom are glued together. The bottom of the bottle is made by molding with three-layer composite paper. The different layers of the three-layer composite paper The fibers are arranged in different directions.

The top end of the upper bottle body and the connection part of the bottle body have a fastening structure, and the fastening structure includes: an inner flange protruding from the top end of the bottle body toward the inner side of the bottle body, and the outer side of the connecting section of the upper bottle body corresponds to The position of the inner protruding edge is provided with a groove, and the groove surrounds the connecting section, and the inner protruding edge can be buckled with the groove.

Wherein, the bottom end of the bottle body and the side wall of the bottle bottom are glued with a fitting groove formed by rolling, and the fitting groove is recessed toward the center of the bottle body and surrounds the bottle body.

Among them, the plant fiber-based mixture contains: natural plant fiber powder and plant-based binders.

The natural plant fiber powder is a plant fiber powder made of bamboo skin, and the plant binder includes any one of natural resin and pine juice.

The advantage and effect of the new all-natural plant material liquid container is that it is completely made of natural plant material, with a specially designed structure, has excellent structural strength, and can It can better withstand radial/lateral pressure, and can be used to contain pressured beverages or liquids such as soda.

The plant-based binder contains any of natural resin and pine juice. It uses all-natural plant materials with the characteristics of natural decomposition or biological decomposition, which can solve the environmental protection problems caused by traditional plastic bottles. The bottle body 30 is made of a spiral paper tube 60 with a multilayer structure (see Figure 4). The top end of the bottle body 30 and the connecting section 22 of the upper bottle body 20 are glued and connected, for example, using biodegradable polylactic acid (Polylactide, PLA) as glue.

The shape of the upper bottle body 20 is not limited to a specific shape. The suitable shape is usually determined according to the purpose and type of the liquid container. The upper bottle body 20 is basically a tubular element connected at both ends; An embodiment of the upper bottle body is a tapered tubular element, but it is not limited to this. The connection method and structure of the bottle cap 10 and the bottle mouth 21 are usually determined according to the purpose and type of the liquid container. Figure 1 shows one of the embodiments. The upper bottle body 20 has an external thread 23 near the bottle mouth 21, and The inner side of the bottle cap 10 also has an internal thread 11 that can be matched with the external thread 23 (see FIG. 3). Therefore, the bottle cap 10 can be connected together by the internal thread 11 and the external thread 23 of the upper bottle body 20.

The bottle bottom 40 is a cup-shaped structure with an opening facing downward. The bottle bottom 40 includes a bottom surface 41 and a side wall 42 surrounding the bottom surface 41. As shown in Figure 7, the bottle bottom 40 is inserted into the bottom of the bottle body 30 with the opening facing downward. Then the side wall 42 of the bottle body 30 and the bottle bottom 40 are combined together in a gluing manner. The bottle bottom 40 is made by molding with a three-layer composite paper P3; please refer to Figure 5, a better In the embodiment, the fiber arrangement direction D of the different layers of the composite paper P3 with a three-layer structure is different (the direction indicated by the arrow in the figure). Using this composite paper P3 to make the bottle bottom 40 can enhance the structural strength of the bottle bottom 40 And compressive strength.

In a preferred embodiment of the present invention, where the bottom end of the bottle body 30 and the side wall 42 of the bottle bottom 40 are glued, there is a rolling groove 43 (see Figure 3), and the groove 43 faces The central direction of the bottle body 30 is recessed and surrounds the bottle body 30, and the fitting groove 43 can improve the reliability and structural strength of the connection between the bottle body 30 and the bottle bottom 40.

In a preferred embodiment of the present invention, the connection between the top end of the upper bottle body 20 and the bottle body 30 has a buckle structure to improve the reliability and structural strength of the connection between the upper bottle body 20 and the bottle body 30. The buckle structure includes: an inner flange 31 protruding toward the inner side of the bottle body 30 at the top end of the bottle body 30, and the inner flange 31 can be formed by curling the paper material at the top end of the bottle body 30 inward. The flange 31 (see Figure 7); the outer side of the connecting section 22 of the upper bottle body 20 corresponds to the position of the inner flange 31 with a groove 24, the groove 24 surrounds the connecting section 22, and the inner flange 31 can be buckled in the groove 24 (see Figure 3). Since the bottle body 30 is made of a spiral paper tube with a multi-layer structure, and the spiral paper tube has excellent structural strength, it can better withstand radial or lateral pressure and tension.
