Problems solved by technology

[0004] Most of the existing plastic bottles have a single-opening structure, which can only hold one kind of liquid. The function is extremely single, which greatly limits the application of plastic bottles, resulting in most plastic bottles being disposable products.

Abstract

The invention discloses a double-opening type interlayer plastic bottle, and belongs to the technical field of plastic bottles. A traditional single-opening structure is changed into a double-opening structure, then an outer bottle body is divided into an inner cavity and an outer cavity through an inner isolation sleeve and a heat preservation bottom plate, different liquids can be contained through an upper opening and a lower opening, meanwhile, the liquid with different temperatures can be contained in the two cavities through a temperature changing piece preset in the inner isolation sleeve, the heat conductivity of the inner isolation sleeve is changed through an electromagnet when needed, the inner isolation sleeve can conduct heat preservation on the liquid and meanwhile can conduct heat so that heat of the two kinds of liquid can be neutralized, the applicability of a plastic bottle is greatly improved, compared with an existing plastic bottle, the plastic bottle can contain two different kinds of liquid, and heat convection can be controlled.

Description

technical field [0001] The invention relates to the technical field of plastic bottles, in particular to a double-opening sandwich plastic bottle. Background technique [0002] Plastic bottles are mainly made of materials such as polyethylene or polypropylene with the addition of various organic solvents. Polyester (PET), polyethylene (PE) and polypropylene (PP) are widely used as raw materials for plastic bottles. After adding corresponding organic solvents, after high temperature heating, they are blown, extruded, or injection molded through plastic molds. plastic container. [0003] It is mainly used for liquid or solid disposable plastic packaging containers for beverages, food, pickles, honey, dried fruits, edible oil, agricultural and veterinary drugs, etc. Plastic bottles have the characteristics of unbreakable, low cost, high transparency, and food-grade raw materials. [0004] Most of the existing plastic bottles have a single-opening structure, which can only co...
