Description

Technical Field

[0001] The utility model relates to the technical field of plastic bottle processing, in particular to a double-layer and double-color plastic bottle. Background Art

[0002] Plastic bottles are a common plastic container, mainly used for packaging beverages, food, cosmetics, medicines and other consumer goods. They are mainly made of plastic materials such as polyester (PET), high-density polyethylene (HDPE), low-density polyethylene (LDPE), polypropylene (PP), polyvinyl chloride (PVC), etc., and are processed by blow molding, extrusion blow molding or injection molding. Plastic bottles are light, not easy to break, low cost, high transparency, easy to carry and store, and their materials are mostly food grade, ensuring the safety of the contents of the package.

[0003] The potential of the double-layer structure of existing plastic bottles, including double-layer plastic bottles, has not been fully explored. The outer layer is often used only for decorative purposes and lacks independent functionality, resulting in inefficient use of materials and resources. On the other hand, its double-layer integrated structure hinders the effective filling and maintenance of the inner layer. The existing double-layer two-color plastic bottles only play the role of aesthetics and heat insulation, and do not maximize their functions, which has caused limitations in practical applications.

[0004] Therefore, the problem with the above-mentioned existing double-layer plastic bottles is that the functional potential of the double-layer structure has not been fully utilized, the outer layer is mostly limited to decoration, lacks independent practical functions, resulting in waste of resources, and at the same time, its integrated design is not conducive to convenient filling and maintenance of the inner layer, and its functions mainly remain in aesthetics and basic heat insulation, and it has failed to achieve wider and more effective applications, resulting in limitations in practical applications, which urgently need to be solved to improve the use scenarios of double-layer and two-color plastic bottles. Utility Model Content

[0005] In order to overcome the common double-layer two-color plastic bottles, the double-layer design is mostly used for decoration only, and is not fully utilized to increase functionality, resulting in waste of resources; and the integrated structure hinders the convenient maintenance and filling of the inner layer, and the function is limited to beautification and simple insulation, limiting the scope of application.

[0006] The technical solution of the utility model is: a double-layer and double-color plastic bottle, including a main body, the lower end of the main body is connected to a base, a double-layer mechanism is arranged inside the main body, and the double-layer mechanism includes an inner wall, a connecting plate, and a threaded groove; the left and right sides inside the main body are connected to connecting plates, two connecting plates are arranged, the inner side of the connecting plate is connected to the inner wall, the outer side of the upper end of the inner wall is provided with a threaded groove, and an assembly mechanism is arranged at the upper end of the main body.

[0007] Preferably, after the inner wall is manufactured, the main body and the inner wall can be connected by a connecting plate, eliminating the traditional one-piece double-layer plastic bottle. This double-layer design can realize other functions, such as pouring water into the gap and freezing it, thereby chilling the water or beverage in the inner wall.

[0008] Preferably, the assembly mechanism includes a threaded ring and an adapter plate; a threaded ring is provided at the upper end of the inner wall, and the upper end of the threaded ring is connected to the adapter plate, and the adapter plate is used to block the gap to prevent the liquid inside the inner wall from penetrating into the gap between the inner wall and the main body.

[0009] Preferably, the assembly mechanism includes an anti-slip groove and an adaptor groove; an anti-slip groove is provided at the outer end of the threaded ring, and an adaptor groove is provided at the lower end of the threaded ring, and the adaptor groove is used to match the inner wall and the main body to facilitate combined installation.

[0010] Preferably, a plurality of anti-skid grooves are provided, and the adapting grooves match the main body, and the anti-skid grooves prevent slipping during disassembly or installation.

[0011] Preferably, the threaded ring is threadedly connected to the threaded groove, the adapter plate and the inner wall match each other, and the adapter plate prevents beverage or liquid on the inner wall from penetrating into the gap.

[0012] Preferably, the main body is made of polypropylene material and the connecting plate is made of polypropylene material. Polypropylene is the most high-temperature resistant of all food-grade plastics and can withstand temperatures up to 140 degrees Celsius. It is suitable for microwave heating, which means that it can still maintain good physical and chemical stability in high temperature environments.

[0013] Preferably, the inner wall is made of polypropylene material and the base is made of copolyester. Compared with traditional PET, PETG has enhanced impact strength and thermoforming ability while maintaining good transparency and food safety. It is suitable for food packaging that requires higher strength, such as salad boxes, jam jars, etc.

[0014] Beneficial effects of the utility model:

[0015] 1. By setting up a double-layer mechanism, the innovative double-layer design improves the overall practicality. For example, by injecting water between the two layers and freezing it, it can provide an instant and continuous cooling effect for the beverage contained therein, without the need to use additional ice cubes. It can quickly achieve the purpose of chilling the beverage and avoid diluting the original flavor of the beverage. The double-layer design unlocks multiple practical potentials, covering a wide range of application scenarios from efficient heat preservation to creative cooling. In conjunction with the assembly mechanism, the main body and the inner wall are tightly connected through a threaded ring, an adapter plate and an adapter groove, so that the inner wall can be used as a container. The modular assembly design is not only convenient for personalized internal filling and realizes diversified solutions, but also can easily achieve a variety of practical or aesthetic effects, while ensuring the convenience of assembly and improving user experience;

[0016] 2. By setting up a double-layer structure, the inner wall and the main body are connected through a connecting plate. The main body and the inner wall can be made separately and then welded through the connecting plate. The threaded ring can be turned to connect with the threaded groove. The adapter groove and the adapter plate are matched with the main body and the inner wall, so that the two are assembled and connected, which increases the strength while improving the overall practicality. It is made of polypropylene and copolyester materials, which improves the heat resistance and overall strength. The double-layer fillable design unlocks multiple practical potentials, covering a wide range of application scenarios from efficient thermal insulation to creative cooling. The modular assembly design greatly enriches the user experience. This design allows users to fill different materials in the gap of the double-layer structure according to their personal preferences, which not only improves the aesthetics of the product, but also further enhances its practicality, truly realizing the perfect fusion of function and aesthetics.
