AI Technical Summary
Technical Problem
The existing lipstick tubes are prone to contamination when the cosmetics are twisted back after use.
Method used
A unidirectional rotating center core was designed. By setting a toothed ring and positioning teeth in the guide element and collar, the cosmetic can be rotated out in only one direction, preventing it from rotating back. The engagement of the toothed ring and positioning teeth produces a sound to control the amount of rotation.
Benefits of technology
It enables unidirectional dispensing of cosmetics by twisting them back, avoiding contamination caused by twisting them back, and provides audible prompts for users to control the amount dispensed, ensuring hygienic use.

Abstract
This application discloses a unidirectional rotating core and packaging tube. The core includes a driving element, a guiding element, a storage element, and a decorative element with spiral grooves on its inner wall. A portion of the storage element extends into the driving element and engages with the spiral grooves. When the driving element and the guiding element rotate relative to each other, the storage element can be driven to move axially. A collar is included, which is fitted onto the driving element and circumferentially fixed relative to it. One of the guiding element and the collar is provided with a toothed ring, and the other with positioning teeth. The toothed ring has multiple circumferentially arranged locking teeth, which engage with the locking teeth, allowing the positioning teeth to rotate relative to the toothed ring in a first direction while preventing them from rotating relative to the toothed ring in the opposite second direction. In this application, the cosmetic contents of the core can only be rotated out and will not retract, causing contamination. Furthermore, because the positioning teeth and the toothed ring engage with a sound, the user can judge the rotation angle by the number of sounds, thus effectively controlling the amount of contents squeezed out.
