Abstract
A dispenser and applicator for liquid cosmetic material, such as liquid, semiliquid or pasty lip or eye cosmetic products, or for microencapsulated liquid products, including a rigid, axially elongated reservoir tube for holding the cosmetic material, a manually operable driver assembly for exerting pressure on the material within the tube, and an applicator tip having a planar woven mesh screen extending across an outlet end opening and molded in the applicator tip. The driver assembly forces the contained material forwardly through the screen, which the user applies to the lip or eye region of the face, or other selected skin area. In the case of a microencapsulated product, the microcapsules rupture when they are pressed against the mesh, releasing their contents.
Claims29
An applicator for liquid material, including:
- (a) a reservoir comprising a rigid, hollow, axially rectilinear reservoir tube for containing liquid material to be dispensed and having a rearward end and an open forward end constituting an opening through which liquid material is discharged from the reservoir, said reservoir tube being substantially uniform in cross-section from end to end;
- (b) manually-operable pressure-applying structure acting on liquid material within the reservoir to force liquid material from the reservoir forwardly through the opening;
- and
- (c) an applicator tip comprising rigid hollow tubular structure having an axis and an open forward end defined by a continuous peripheral edge of the tubular structure lying in a plane oblique to said axis, and, fixedly secured to said edge and located entirely interiorly thereof, a porous planar mesh membrane extending entirely across said open forward end and lying substantially in said oblique plane, said tip being disposed at said opening such that liquid material discharged from said reservoir passes through said membrane, said tubular structure being axially rectilinear, having an open rearward end of substantially the same cross-section as the reservoir tube, and being disposed at said open forward end of said reservoir tube in coaxial relation thereto with said rearward end of said tubular structure opening into said reservoir tube, and said membrane remaining substantially planar during use to apply liquid material.

A dispenser for liquid cosmetic material, including:
- (a) a body of liquid cosmetic material to be dispensed;
- (b) a reservoir comprising a rigid, hollow, axially rectilinear reservoir tube containing said body of liquid cosmetic material and having a rearward end and an open forward end constituting an opening through which liquid material is discharged from the reservoir, said reservoir tube being substantially uniform in cross-section from end to end;
- (c) manually-operable pressure-applying structure acting on liquid cosmetic material within the reservoir to force liquid cosmetic material from the reservoir forwardly through the opening;
- and
- (d) an applicator tip comprising rigid hollow tubular structure having an axis and an open forward end defined by a continuous peripheral edge of the tubular structure, and, fixedly secured to said edge and located entirely interiorly thereof, a porous planar mesh membrane extending entirely across said open forward end, said tip being disposed at said opening such that liquid cosmetic material discharged from said reservoir passes through said membrane, said tubular structure being axially rectilinear, having an open rearward end of substantially the same cross-section as the reservoir tube, and being disposed at said open forward end of said reservoir tube in coaxial relation thereto with said rearward end of said tubular structure opening into said reservoir tube, and said membrane being a woven synthetic fiber mesh that remains substantially planar during use to apply liquid material.

A dispenser for microencapsulated liquid material, including:
- (a) a quantity of microcapsules of a liquid material to be dispensed;
- (b) a reservoir containing said quantity of microcapsules and having an opening for discharge of material from the reservoir, and
- (b) manually-operable pressure-applying structure acting on the quantity of microcapsules within the reservoir to advance microcapsules of said quantity forwardly to the opening,
- wherein the improvement comprises:
- (c) an applicator tip comprising rigid hollow tubular structure having an axis and an open forward end defined by a continuous peripheral edge of said tubular structure, and, fixedly secured to said edge and located entirely interiorly thereof, a porous planar mesh membrane extending entirely across said open forward end, said tip being disposed at said opening such that microcapsules advanced forwardly through said reservoir to the opening are forced against and ruptured by said membrane.
