Abstract
An applicator for applying a substance includes an applicator element (e.g., bristles). In some examples, the applicator may include a bundle of bristles having at least one of bristles of at least two kinds, bristles of non-circular cross-section, and bristles that are not rectilinear. The applicator may also include a stem supporting the bundle of bristles, and a sheath cooperating with the stem over at least a fraction of a length of the stem to form a space configured to contain a portion of a substance to be applied.

An applicator for applying a substance, comprising:
- a bundle of bristles comprising at least one of bristles of at least two kinds, bristles of non-circular cross-section, and bristles that are not rectilinear;
- a stem supporting the bundle of bristles;
- and
- a sheath cooperating with the stem over at least a fraction of a length of the stem to form a space configured to contain a portion of a substance to be applied;
- wherein the stem is fixed axially with respect to the sheath.
An applicator comprising:
- an applicator element;
- a stem supporting the applicator element;
- and
- a sheath cooperating with the stem over at least a fraction of a length of the stem to form a space configured to contain at least a portion of a substance to be applied, the sheath and the stem comprising cross-sections arranged such that the space defines a width that varies around the stem over at least a fraction of the length of the stem,
- wherein the sheath includes at least one lateral opening enabling a fluid communication between the space and an outside of the sheath.
An applicator for applying a substance, comprising:
- a bundle of bristles comprising at least one of bristles of at least two kinds, bristles of non-circular cross-section, and bristles that are not rectilinear;
- a stem supporting the bundle of bristles;
- and
- a sheath cooperating with the stem over at least a fraction of a length of the stem to form a space configured to contain a portion of a substance to be applied;
- wherein the sheath has a free end portion having an opening;
- and
- wherein an interior of the free end portion does not taper toward the opening.
An applicator for applying a substance, comprising:
- a bundle of bristles comprising at least one of bristles of at least two kinds, bristles of non-circular cross-section, and bristles that are not rectilinear;
- a stem supporting the bundle of bristles;
- and
- a sheath cooperating with the stem over at least a fraction of a length of the stem to form a space configured to contain a portion of a substance to be applied;
- wherein the bundle of bristles comprises at least one straight bristle and at least one undulating bristle;
- and
- wherein a percentage of straight bristles in the bundle ranges from about 60% to about 80%, and a percentage of undulating bristles in the bundle ranges from about 20% to about 40%.
