Wiper Device for an Applicator for a Cosmetic Product

Abstract

A one-piece wiper device for an applicator assembly for paste-like cosmetic product that includes an applicator provided with a gripping rod and a means for applying said cosmetic product; a container having a neck in which said applicator slides along a longitudinal axis XX. The wiper device has a cylindrical shape adjustable inside the neck and is provided with a first flange for attachment thereof on the edge of the neck and a second flange for attachment thereof on an inner shoulder of the neck and a lip protruding inside said container. The device according to the invention also includes an outer external protrusion externally supporting at least one additional element suitable for coming into contact with the inner surface of the shoulder of the neck when the device is engaged on said neck.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a wiper device for an applicator assembly for applying a liquid, paste-like or powdered cosmetic product such as mascara or eyeliner.PRIOR ART[0002]An applicator assembly of this type conventionally comprises a bottle intended to contain the cosmetic product and provided with a threaded neck onto which a cap may be screwed. This cap bears a rod, the end of which is provided with an applicator for the product to be applied. Thus, the applicator is immersed in the product contained in the bottle and preferably, an applicator assembly of this type further comprises a wiper component for wiping (or wringing out) the rod and / or the applicator when it is taken out of the bottle.[0003]In general, the efficiency and the main function of a wiper are linked to the geometry of the wiper. The external geometry of the wiper must allow it to be easily fitted in the neck of the holder or container, while keeping it firmly in position dur...

AI Technical Summary

Benefits of technology

The invention is a one-piece wiper device for a container with an applicator. It aims to strengthen the attachment of the wiper to the container by using a flange and lip to compensate for dimensional irregularities in the container neck. The wiper may also have studs or protrusions to improve grip on the container shoulder. This design allows for easier attachment and better grip when using the container and applicator.

Problems solved by technology

The problem consists in holding the wiper in place as the rod, and in particular the applicator device, passes through, the latter passing through the narrowed opening of the wiping lip, causing it to deform considerably, subjecting it to a tensile stress.

Another problem encountered relates to the disparities in the shape of the containers, in particular at the neck, regardless of the material from which the container is made.

These irregularities essentially result from manufacturing, and the dimensional differences can be significant.

These anomalies can contribute to the wiper being held less securely in the neck.

Furthermore, the fillet radius between the neck opening and the shoulders is very approximate and the dimension thereof is not guaranteed in this type of process.

Plastic containers, especially when made by blow molding, do not make it possible to ensure a regular position of the shoulders inside the neck regardless of the quality of production.

Furthermore, the fillet radius between the neck opening and the shoulders is very approximate and the dimension thereof is never guaranteed.
