FRESH-KEEPING VACUUM BOTTLE WITH TWO COMPARTMENTS

Abstract

A fresh-keeping vacuum bottle with two compartments for preserving freshness, specifically designed to tackle the technical challenges faced by existing similar products in packaging powder products like freeze-dried powder, for example, prone to moisture, and challenged to reuse and assemble as replacement bottles. The bottle mouth of the vacuum bottle body and the large circle are connected through snap fitting to create a lower liquid storage compartment. The large circle includes a fixed large circle, a rotating large circle, and an inner sleeve large circle, with the fixed large circle being connected through snap fitting to the mouth fixed on the bottle body. The rotating large circle rotates the sealing plug until the upper thru-hole of the rotating large circle, the middle thru-hole of the sealing plug, and the lower thru-hole of the fixed large circle are aligned sequentially to achieve dual-compartment mixing.

[0031] In summary, the vacuum bottle is a form of packaging for cosmetic products, which is mainly used to hold the ingredients of cosmetic products unaffected by the external environment, in order to prolong their freshness and maintain the quality and effectiveness of the products, so as to maintain the stability of the ingredients, provide better sealing performance, and enhance the user experience. The vacuum bottle comprises of two parts: an inner bottle, which is a small airtight container that holds the cosmetic ingredients, and an outer bottle, which is an outer container that protects the inner flask and provides additional sealing and stability. During the manufacturing process, the inner bottle is placed inside the outer bottle and the air between the two is extracted through a special process and sealing technology, creating a vacuum environment; this vacuum prevents air, moisture and other harmful substances, thereby minimizing oxidation, bacterial growth, and other factors that could compromise the cosmetic ingredients.
