Improved fluid bottle cap

Abstract

An improved fluid bottle cap comprises an upper cap body and a lower cap body. The inner side of the side wall of the upper cap body is provided with an internal thread, the inner side of the side wall of the lower cap body is provided with an internal thread as well, the upper cap body is arranged over the lower cap body, the upper cap body and the lower cap body are connected through a pull ring, an airtight storage container is arranged inside the upper cap body, the upper end of the storage container is fixedly connected with the upper cap body, the lower end of the storage container is provided with a layer of sealing film, a feed opening is arranged in the lower cap body and enables the upper side and the lower side of the lower cap body to be communicated, an upward-protruding sharp item is arranged in the lower cap body, and the sharp item is located in the feeding opening and under the storage container and is connected with the lower cap body through a support. Solid powder or concentrated fluid is added into the storage container which is then sealed, the upper cap body and the lower cap body are connected through the pull ring, and packaging is carried out to form a finished product. During use, the lower cap body is connected with a drinking water bottle body, the pull ring is removed, the upper cap body is rotated, the sealing film is pierced by the sharp item, and the solid powder or concentrated fluid flows into the drinking water bottle body for mixing.

Description

Technical field: [0001] The invention relates to the packaging field, in particular to food and medicine containers, in particular to an improved liquid bottle cap. Background technique: [0002] Bottled liquid beverages in the prior art all directly mix the liquids, add preservatives, bottling them after high-temperature sterilization and putting them on the market for people to drink. The bottled beverages will precipitate after being stored for a long time, and the shelf life is relatively short. Long-term consumption of additives will have an impact on human health. In addition, beverage manufacturers need to produce a large amount of mixed liquid, and the production cost is relatively high. Invention content: [0003] The purpose of the present invention is to provide an improved liquid bottle cap, which solves the technical problems in the prior art that bottled beverages have sedimentation, short shelf life and high production cost. [0004] An improved li...
