Abstract
A device for packaging and applying a product includes a container to hold the product, with this container having an opening at its upper end, a wiper element engaged at least partially in the opening, an applicator including an applicator element carried by a rod of axis X, and a closure element for the container. The wiper element includes a sealing zone against which part of the rod is capable of coming into leaktight contact when the closure element is in the closed position, and a zone of greater deformability, located above the sealing zone, and which is capable of stretching axially when the rod is bearing against the sealing zone of the wiper element.
Claims39
A device for packaging and applying a product including:
- a container which can hold the product, the container including an opening at its upper end;
- a wiper element at least partially engaged in the opening;
- an applicator including an applicator element carried by a rod;
- and
- a closure element for the container;
- wherein the wiper element includes:
- a sealing zone against which part of the rod comes into leaktight contact when the closure element is in a closed position;
- and
- a zone of greater deformability, located above the sealing zone, which is capable of stretching axially when the rod bears against the sealing zone of the wiper element;
- wherein the sealing zone of the wiper element is delineated by a shoulder;
- and
- wherein the shoulder delineates a conical surface converging towards the opening of the container.

- and
- a zone of greater deformability, located above the sealing zone, which is capable of stretching axially when the rod bears against the sealing zone of the wiper element;
- wherein said sealing zone includes a shoulder which protrudes radially inwardly from an inside of said wiper element and said part of said rod includes a shoulder which protrudes radially outwardly from said rod;
- wherein said shoulder of said rod also includes a portion which protrudes in an axial direction;
- wherein said shoulder of said sealing zone of said wiper element also protrudes in an axial direction opposite to the axial direction which the shoulder of said rod protrudes;
- and
- wherein the shoulder of the rod forms a section of a cone and the shoulder of the sealing zone forms a section of a cone.
