Description

Technical Field

[0001] The utility model relates to the technical field of bottle cap production, in particular to an aluminum foil sealing tool for the production of press-type bottle caps. Background Art

[0002] Premixed liquids, such as beverages and oral liquids, are frequently used in the food and health product sectors. However, a major challenge with premixed liquids is their susceptibility to degradation and loss of activity due to external factors, such as light, heat, oxygen, and ultraviolet light. Consequently, preservatives, stabilizers, and other additives are often added. However, even with these additives, the shelf life of premixed liquids remains shorter than that of solids. Furthermore, the flavor of liquid formulations changes over time and due to environmental factors during storage, hindering the development of various food products. For example, anthocyanin-containing, vitamin-containing, and probiotic-containing beverages significantly shorten their activity after mixing with water. With rising living standards, people are increasingly seeking healthier bottled beverages. If a beverage bottle cap could be designed that could store solid ingredients and allow for on-demand dispensing, the nutritional ingredients would be isolated from water before use, preserving the active ingredients and ensuring ready-to-use dispensing. This would allow manufacturers to avoid the use of preservatives and stabilizers, while providing consumers with a reliable product. This design concept has been widely recognized.

[0003] To this end, our company has designed an aluminum foil sealing tool for the production of push-type bottle caps. The bottle cap includes a lower cover, an upper cover, a powder storage inner cover, an inner plug and an aluminum foil sheet. During the production process, the aluminum foil sealing tool is required to install the aluminum foil sheet at the bottom end of the lower cover.

[0004] Traditional aluminum foil sealing tooling has shortcomings. Because the tube at the bottom of the lower cap, where the aluminum foil is installed, is thin, poor sealing can occur after the foil is installed. This can cause the liquid in the bottle to mix with the powder prematurely, affecting product quality. Therefore, it is necessary to optimize and improve the traditional aluminum foil sealing tooling to better meet the production needs of push-type bottle caps. Utility Model Content
