摘要

A rotatable action container for the selective advancement and retraction of a lipstick or a similar product by means of an open delivery end of the container, comprising relatively rotating inner and outer tubular members having cam profiles for advancing and a carrying member guided inside the inner tubular member and having cam follower means following the cam profiles of both tubular members, the outer tubular member being an open ended bushing with its cam profile substantially along its entire length and within its bore, the inner tubular member having a slotted cam profile and extending along the bore of the outer tubular member and including a drive handle projecting axially beyond said outer tubular member at the other end, the material of said inner tubular member elastically deformable and with a tension-free contour generally conical on a fraction as a minimum of the axial extension of the cam profile practiced therein, whose conical contour extends from a minimum diameter near the end of the handle to a maximum diameter closer to the delivery end, saving said diameter minimum and exceeding said maximum diameter the effective diameter of the bore of the outer tubular member, and axial locating means cooperating between said tubular members to retain the assembly of said members, with said conical contour deformed elastically and radially inwardly to elastically loaded contact and continuous friction with the bore of said outer tubular member.
