Description

a bottle cap

【Technical field】

The utility model relates to a bottle cap, in particular to a bottle cap capable of containing solid powder or concentrated liquid.

【Background technique】

In the prior art, some combination beverages made by mixing solid powder or concentrated liquid with water are difficult to preserve or unstable due to their inherent characteristics. In order to improve the shelf life, people put the solid powder or concentrated solution in the bottle cap in a utility model, so that the solid powder or concentrated solution is separated from the water in the bottle, and the solid powder or concentrated solution is mixed with the water in the bottle before drinking. This scheme is easier to preserve and stable.

The Chinese patent titled "storage bottle cap" with the application number "200610200754.7" discloses a storage bottle cap, which mainly includes parts such as a top cover, a tube holder, and a storage tube. Through the linkage between the top cover and the storage tube, To make the tube holder puncture the film seal at the opening of the storage tube, so that the solid powder in the storage tube is mixed with the water in the bottle; but this solution has the following disadvantages:

First: In order to conform to ergonomics, the diameter of the mouth of the beverage bottle is generally designed to be 25mm to 38mm. Based on this condition, with this solution, the volume of the storage cylinder is too small to accommodate more solid powder or concentrated liquid;

Second: After the top cover is opened, the storage tube will stay in the tube holder, blocking the mouth of the bottle and affecting the speed at which the liquid in the bottle is poured out;

Third: the scheme is complex in structure and high in cost.

Fourth: The puncture circle of the sealing film is not easy to control, and the puncturing effect on the sealing film often exceeds 360°, causing the sealing film to fall into the beverage in the bottle, which is unhygienic, and even the sealing film will be drunk with the drink Gastrointestinal, risk of personal injury.

The utility model researches and proposes aiming at the deficiencies in the prior art.
