Description

Technical Field

[0001] The utility model relates to a packaging bottle cap, in particular to a bottle cap for storing additives. Background Art

[0002] Bottle caps are important structures for sealing the liquid in the bottle and are widely used in bottled products of different liquids. However, most bottle caps are ordinary bottle caps with snap-on or threaded structures, which only play the role of sealing and preventing the external environment from polluting the contents of the packaging bottle. Most mixed liquids such as liquid beverages, liquid medicines, and liquid reagents are prepared by adding ingredients to water before leaving the factory, and then directly poured into the bottle, sealed with bottle caps, and then shipped to the market for sale. Mixed liquids are prone to various changes. In order to ensure that the mixed liquid does not deteriorate and extend the shelf life, manufacturers have to add preservatives, stabilizers and other artificial chemical synthetic substances. These preservatives not only affect the flavor of beverages, the efficacy of medicines, and the purity of reagents, but are also not good for human health.

[0003] To solve the above problems, a few bottle caps that can separate ingredients and water have appeared on the market. The principle is: the ingredients are sealed in the bottle cap with a sealing film such as aluminum foil, and a piercing component is provided. When in use, the sealing film is pierced by pressing or rotating the piercing component, so that the stored ingredients fall into the bottle and mix with the water in the bottle. After fully shaking, the bottle cap is opened by twisting to drink or use. This kind of bottle cap does not require additional preservatives and is more beneficial to health. However, this kind of bottle cap has some shortcomings:

[0004] The main problems are that the water does not flow smoothly, the loading process is complicated, and the operation is inconvenient when drinking. This type of bottle cap generally uses aluminum foil as a sealing film, and the falling of the ingredients is affected by the cracks in the aluminum foil. Due to the limitations of its material properties, the size of the cracks is usually different. Usually, the crack area is small, which makes it difficult for the ingredients to fall and dissolve incompletely. Especially for some thick or large-particle ingredients, they are easy to remain and agglomerate, and adhere to the aluminum foil to hinder the water flow, resulting in unsmooth water flow, affecting the drinking experience. The assembly process is complicated because this type of bottle cap requires the puncture component to be installed into the bottle cap first, and then the bottle cap is inverted to add the ingredients, and then sealed with aluminum foil. Not only is the entire assembly process cumbersome, but the ingredients are easy to spill during this process. At the same time, the aluminum foil also requires high-temperature welding, which may cause the added ingredients to deteriorate during the high-temperature welding process. The operation is not convenient because each time you drink or use it, you need to repeatedly twist and disassemble and reinstall the bottle cap with both hands, which does not meet the one-handed operation scenarios such as driving and sports, and the bottle cap is easy to lose or fall and contaminate after it is removed.

[0005] Secondly, its disadvantages are that the puncture parts are not sealed enough, the moisture-proof effect is poor, and the sealing is reduced after operation, and there are gaps that allow liquid to leak out. In addition, aluminum foil is not acid- and alkali-resistant, which limits the type of ingredients, is not easy to recycle, cannot be degraded, and is not environmentally friendly.
