Method of manufacturing retractable product stick dispenser
A recently granted patent (Publication Number: US12011896B2) discloses a method for manufacturing a dispenser for stick-form products. The dispenser includes an inner tube and a retractable product concealing tube with a guide element for exposing and covering the product stick. The method involves wrapping a first blank around a mandrel to form the inner tube, applying a bonding agent to a second blank with a slot and guide element, wrapping the second blank around the inner tube to create the product concealing tube, and ensuring the guide element cooperates with the recess in the tube for smooth movement.
Furthermore, the patent details various aspects of the manufacturing method, such as the configuration of the slot in the second blank, the positioning of the product concealing tube relative to the inner tube, and the use of single-piece blanks for construction. The method also includes fixing an outer tube relative to the inner tube to encase the product concealing tube. The dispenser design allows for the product concealing tube to be slidably and rotatably movable along a helical path, providing ease of use and efficient product dispensing. The patent emphasizes the unique features of the dispenser, including the guide element's role in defining fully retracted and extended positions of the product concealing tube, ensuring precise and controlled movement for optimal functionality.
