Abstract
An applicator may include a stem, a closure element configured to close a receptacle, and a bundle of bristles including a cross-section of elongate shape along a major axis thereof. The closure element may be at a first end of the stem. The bundle of bristles may be at a second end of the stem, remote from the first end of the stem. The bundle of bristles may include, as observed perpendicularly to the major axis, a beveled end. An angle at a tip of the bevel may lie in a range of about 10° to about 35°.
Claims27
An applicator comprising:
- a stem having at least one groove and presenting a longitudinal axis;
- a closure element configured to close a receptacle, said closure element being at a first end of the stem;
- and
- a bundle of bristles presenting a cross-section, taken perpendicular to the longitudinal axis of the stem, of generally flat shape and elongate along a major axis of the cross-section, said bundle of bristles being at a second end of the stem, remote from the first end of the stem, and comprising, when observed perpendicularly to the major axis, a beveled end with an angle at a tip of the bevel lying in a range of about 10° to about 35°,
- wherein the at least one groove on the stem opens substantially mid-way across the bundle of bristles.
