Patent ID: 8007191

Claim:
A packaging and/or applicator device comprising: a first element including an axis and at least one slot extending not entirely perpendicularly to the axis over an angle smaller than 180 degrees; and a second element that is engaged, at least in part, inside the first element, and that is rotatable relative to the first element about the axis, and that is axially movable in the first element, the second element including at least one lug that is engaged in the slot and that is visible from an outside of the device, the at least one lug having a length that is less than a thickness of a wall of the first element in which the at least one slot is formed; the slot and the lug being configured in such a manner that displacement of the lug in the slot while the first and second elements are turning relative to each other causes the first and second elements to be displaced axially relative to each other, the first and second elements being configured to enable the lug to be inserted into the slot by elastically deforming at least one of the first and second elements, while the second element is being displaced inside the first element.
