Description

Technical Field

[0001] This utility model relates to a beverage bottle structure, particularly for situations where two ingredients need to be stored separately before consumption. Background Technology

[0002] Some beverages require the raw materials and solutions to be stored separately before consumption. The raw materials can be solid or liquid. In order to facilitate sales and use, a beverage bottle with a split structure needs to be designed to achieve the effect of separate storage and convenient mixing before consumption.

[0003] In existing technologies, a diaphragm is typically placed on the beverage bottle to divide the bottle into upper and lower cavities. The diaphragm is punctured before drinking. For example, CN219970548U discloses a screw-on beverage bottle cap, including a cylinder, a cap, and a rotating cylinder. Utilizing the rotation of the cap, it employs a ratchet-like structure where a limiting block on the rotating cylinder and a groove on the inner wall of the solvent cavity of the cylinder allow only unidirectional rotation. Furthermore, the pitch of the rotating cylinder thread on the outer wall of the upper end of the rotating cylinder and the inner cap thread on the inner cap wall is greater than the pitch of the thread on the outer edge of the upper end of the cylinder and the inner thread on the inner cap wall. This screw-on beverage bottle cap allows for the automatic preparation of two different solute beverages by simply unscrewing the cap. The drawback of this structure is its excessive complexity. When rotating the cap, a specific pattern must be followed to lock the ratchet, requiring general consumers to learn how to use it. Utility Model Content
