Abstract
A device for closing a container having a neck, in particular a bottle or pot for a cosmetic product, of the type having structure for axial tightening by screwing of a cap onto the neck of the container and for the angular positioning of the cap with respect to the container. The angular positioning structure comprises at least one lug of the container extending substantially axially upwards from a shoulder surface of the container substantially perpendicular to the tightening axis and at least one tongue member of the cap which is elastically deformable in the axial direction co-operating with such lug in order to vary the axial tightening force at the time of the opening and closing operations.
Claims7
A device for closing a container having a neck, in particular a bottle or pot for a cosmetic product, comprising a container, a cap therefor, tightening means for axially tightening a cap on the neck of the container by screwing the cap and positioning means for angularly positioning the cap with respect to the container, the positioning means comprising a lug on the container and an elastic tongue on the cap, the lug on the container extending substantially axially upwards from a shoulder surface of the container in a direction substantially perpendicular to a central longitudinal axis passing through the container neck;
- the tongue on the cap being depressible axially in an upward direction toward the cap under the action of said lug on the container and having a free edge opposite a free end of said lug, said free edge forming an angular end-of-travel stop cooperating with said lug at the end of screw travel in order to lock the cap in an angular manner with respect to the container when the cap and container arrive at an aligned closure position.
