Description

Technical Field

[0001] The utility model relates to the technical field of bottle caps, in particular to a split double-piece crystal bottle cap. Background Art

[0002] There are two types of 38mm and 3025 bottle caps currently available for food and beverages on the market. One is a standard one-piece cap, with the inner plug and screw thread integrated. It can only be produced in one color and made of PE. The original color lacks high transparency, resulting in poor display quality. The other is a 38mm two-piece cap, a secondary molded cap made of PP. After compression molding, it is glued onto the inside of the cap to form a sealant. This cap lacks an inner plug. Because it is made of PP and has a high transparency in its original color, it is more stylish and has a more upscale appearance than standard one-piece caps. However, it has the following drawbacks:

[0003] 1. Domestic beverage filling equipment is uneven, and it is very easy for the cap to be loose during filling. Because the top seal is made by a rubber gasket, if the cap is not tight, it will cause a loose seal and cause the beverage and food to deteriorate.

[0004] 2. In order to tighten the cap, the torque of the capping equipment will be increased, but it will also cause excessive torque, which can easily cause the cap and the PET bottle screw threads to lock, making it difficult or impossible for consumers to open the bottle.

[0005] 3. Because this type of lid is sealed with a rubber gasket on the top and has no inner plug, some consumers may accidentally loosen the lid when the beverage is displayed on supermarket shelves. Although the lid is intact and appears to be unopened, the bottle has leaked and air has entered. After a period of time, it will deteriorate and pose a food safety hazard. Utility Model Content
