Description

Technical Field

[0001] This utility model relates to the field of cosmetic packaging, specifically to a screw-top pearl cream bottle. Background Technology

[0002] In the cosmetics packaging industry, cream jars are important containers for storing and displaying various creams and lotions. Their design not only affects the product's aesthetics and practicality but also directly impacts the consumer's user experience. Traditional cream jars often take the form of press-type, squeeze-type, or wide-mouthed bottles. Each of these designs has its advantages and disadvantages, but there is still room for improvement in meeting the preservation needs of specific cosmetics (such as high-end skincare products like pearl creams) and enhancing user convenience.

[0003] The existing pearl cream jars still have some problems when used:

[0004] (1) In many existing pearl cream bottle designs, the inner liner is usually fixed inside the bottle body, making it difficult for users to easily remove the inner liner after the cream is used up. This not only limits the reuse of the inner liner, but also leads to the direct disposal of the entire bottle after the cream is used up, resulting in a great waste of resources.

[0005] (2) Traditional pearl cream bottles often have insufficient sealing, especially at the connection between the bottle mouth and the inner liner. If the seal is not tight, oxygen and moisture in the air may enter the bottle, causing the cream to oxidize and deteriorate, and bacteria to grow, thus affecting the quality and shelf life of the product.

[0006] Therefore, we made improvements and proposed a screw-top pearl cream bottle. Utility Model Content

[0035] To address the technical problems in the background section, the following screw-cap pearl cream jar is provided:

[0036] Combination Figure 1 - Figure 5 As shown, the screw-cap pearl cream bottle provided by this utility model includes a bottle body 1, an inner liner 2 that is snapped into the inside of the bottle body 1, and a sealing cap 3 provided on the upper side of the inner liner 2. The sealing cap 3 is connected to the inner liner 2 by a snap-fit ​​connection, and a bottle cap 4 is provided on the upper side of the sealing cap 3. A connecting mechanism 5 is provided between the bottle cap 4 and the bottle body 1, a sealing mechanism 6 is provided between the sealing cap 3 and the inner liner 2, and a fixing mechanism 7 is provided between the bottle body 1 and the inner liner 2. The connecting mechanism 5 includes a slide groove 501, and the slide groove 501 is formed on the outer surface of the top of the bottle body 1. Four slide grooves 501 are formed on the surface of the bottle body 1, and the slide grooves 501 are arranged in an L shape. Four locking blocks 503 are fixedly installed at the bottom of the inner wall of the bottle cap 4, and the locking blocks 503 are connected to the slide grooves 501 by a sliding connection. A slot 502 is formed on one side surface of the slide groove 501, and the locking blocks 503 are connected to the slot 502 by a snap-fit ​​connection.

[0037] In this embodiment, four L-shaped grooves 501 on the top outer surface of the bottle body 1 form a sliding connection with four locking blocks 503 fixed to the bottom of the inner wall of the bottle cap 4. When installing the bottle cap 4, the locking blocks 503 are slid into the grooves 501 from the top. Then, the bottle cap 4 is rotated in one direction, and the locking blocks 503 can move smoothly within the grooves 501 until they are locked into the preset slots 502, achieving a stable locking connection. This design simplifies the opening and closing operation and ensures a tight fit between the bottle cap 4 and the bottle body 1, effectively preventing accidental leakage of the cream. At the same time, the combined effect of the sealing mechanism 6 and the fixing mechanism 7 further improves the sealing performance of the product and the reusability of the inner liner 2.
