Benefits of technology

This patent describes a wiper for a cosmetic applicator that has a holding section for fastening to a cosmetic reservoir. The wiper has multiple wiper blades, each consisting of a blade shaft and a wiper fin. The wiper blades are positioned at different distances from the holding section. The invention eliminates the need for a constriction or constrictions through which the applicator must be "squeezed" under a full load. Instead, the set of applicator bristles must first pass through a set of wiper segments that interact only locally with the bristles and are situated at different heights. This results in a more effective wiping action and a better wiping result.

Problems solved by technology

If the inner diameter of the wiper lip of such a wiper is comparatively large, then the wiper does not present an excessive resistance to the removal of the applicator, but leaves a very large amount of cosmetic compound in the set of bristles.
At the same time, however, this significantly increases the resistance that must be overcome when the applicator is pulled out through the wiper.
In many cases, this trade-off results in the fact that in the design of the applicator, a particular diameter ratio must be maintained between the applicator shaft and the core of the applicator supporting the bristles, which limits the design possibilities.

Embodiment Construction

[0042]Before a description of the exemplary embodiments is given here, it should be noted that when the terms “distal” and “proximal” are used in the following, the distal end generally refers to the end oriented toward the interior of the reservoir while the proximal end refers to the end oriented toward the withdrawal opening of the reservoir.

[0043]FIGS. 1 through 6 show a first exemplary embodiment of the invention.

[0044]As is quite clear from FIG. 1, the component—referred to as a whole as the wiper 1—of the first exemplary embodiment is composed of a holding section 2 and a number of wiper blades 3, which are attached to the distal end of the holding section, i.e. the end oriented toward the inside of the reservoir, and together, constitute the actual wiping element of this wiper. When the wiper is used for mascara applicators, the outer diameter of this holding section is usually less than 10 mm. It follows from this that when used for mascara applicators, the wiper as a whole...

Abstract

The invention relates to a wiper for wiping a cosmetic applicator. The wiper has a holding section for fastening the wiper to a cosmetic reservoir. The wiper also has a number of wiper blades, which are each composed of a blade shaft that transitions distally into a wiper fin and the wiper has wiper fins that are situated different distances from the holding section.

Description

FIELD OF THE INVENTION[0001]The invention relates to a wiper. Such a wiper is used to wipe excess cosmetic compound from an applicator that is dipped into the cosmetic compound and then pulled out of the cosmetic reservoir through the wiper in order to apply a particular quantity of the cosmetic, preferably without clumping. In particular, the invention relates to a wiper for applicators of mascara compound.BACKGROUND OF THE INVENTION[0002]Numerous designs of applicators have been disclosed in the prior art. Mostly, these wipers are embodied in the form of sleeves or tubular elements that taper at one end, like a truncated cone in the broadest sense. The truncated cone-shaped section constitutes a wiper lip extending in the circumference direction, usually in a completely closed fashion or divided into closely spaced segments of a circle, for example as shown in FIG. 13.[0003]In dimensioning such a wiper lip, a considerable amount of allowances must be made for the diameter of the s...
