Abstract
The present invention generally relates to a wiper which can be easily inserted into neck of a cosmetic container. The wiper is fabricated from elastomeric material and comprises a plurality of collapsible members configured to collapse horizontally on an exterior surface of the wiper when under stress. The plurality of collapsible members also serves as locking features by which it can be retained in the container neck. The wiper of the present invention can be particularly advantageous for use in the field of cosmetics, especially fluid cosmetic products.
Claims17
A wiper configured to be mounted on a cosmetic container, the wiper comprising:
- a tubular body having an exterior surface and an interior surface;
- the tubular body having an upper section and a lower section;
- at least two collapsible members protruding from the exterior surface of the tubular body;
- wherein each of the at least two collapsible members has a joining side surface;
- wherein each of the at least two collapsible members is attached to the exterior surface of the tubular body through the joining side surface;
- wherein the joining side surface is connected along its length to the exterior surface of the tubular body in a direction parallel to a longitudinal axis of the wiper;
- wherein when the wiper is inserted into the cosmetic container, a free end of each of the at least two collapsible members moves in a circumferential direction to the tubular body and in a plane normal to the longitudinal axis of the wiper, from a non-collapsed position to a collapsed position;
- and
- wherein in the collapsed position the at least two collapsible members are closer to the tubular body than in the non-collapsed position.
A wiper, configured to be mounted on a cosmetic container, the wiper comprising:
- a tubular body having an exterior surface and an interior surface;
- the tubular body having an upper section and a lower section;
- at least two collapsible members protruding from the exterior surface of the tubular body;
- wherein each of the at least two collapsible members has a joining side surface which is elongated along a longitudinal axis of the wiper;
- wherein each of the at least two collapsible members is attached to the exterior surface of the tubular body via its joining side surface;
- wherein the joining side surface is connected along at least a length of the lower section of the tubular body;
- wherein when the wiper is inserted into the cosmetic container, each of the at least two collapsible members flexes in a plane normal to the longitudinal axis of the wiper, from a non-collapsed position to a collapsed position;
- wherein in the collapsed position the at least two collapsible members are closer to the tubular body than in the non-collapsed position;
- and
- wherein each of the at least two collapsible members further has an upper surface, a concave side surface and a convex side surface, and wherein the concave side surface faces the exterior surface of the tubular body and the convex site surface faces away from the exterior surface of the tubular body.
A wiper according to calm 11, wherein an outer dimension of the lower section of the tubular body is greater than an internal diameter of the neck of the cosmetic container and wherein deformation of the lower section and collapsing of the at least two collapsible members reduce the outer dimension of the lower section of the tubular body when the wiper is inserted into the neck of the cosmetic container.
A wiper configured to be mounted on a cosmetic container, the wiper comprising:
- a tubular body having an exterior surface and an interior surface;
- the tubular body having an upper section and a lower section;
- at least two collapsible members protruding from the exterior surface of the tubular body;
- wherein each of the at least two collapsible members has a joining side surface;
- wherein each of the at least two collapsible members is attached to the exterior surface of the tubular body through the joining side surface;
- wherein a free end of each of the at least two collapsible members is capable of moving a circumferential direction to the tubular body and in a plane substantially normal to the longitudinal axis of the wiper, from a non-collapsed position to a collapsed position;
- and
- wherein in the collapsed position the at least two collapsible members are closer to the tubular body than in the non-collapsed position.
