Abstract
An applicator is provided for distributing a substance onto a target surface. The applicator includes a first side, a second side, and an internal cavity between said first and second sides. The applicator also comprises at least one opening and at least one substantially fluid-impervious barrier layer within the internal cavity adjacent at least one of the sides. The applicator also comprises a first rupturable, product-containing, flexible film reservoir comprising at least one co-extruded film. A product is released to the target surface upon application of pressure to said reservoir.
Claims19
An applicator for distributing a product onto a target surface, said applicator having a first side, a second side, and an internal cavity disposed between said first and second sides, said applicator further comprising:
- (a) at least one substantially fluid-impervious barrier layer disposed within said internal cavity adjacent at least one of said sides;
- and
- (b) a first rupturable, product-containing, non-laminated flexible film reservoir comprising at least one co-extruded film disposed adjacent to said barrier layer;
- and,
- wherein said product is released from said reservoir through said applicator to said target surface in response to an application of pressure to said reservoir.
A method for forming an applicator for distributing a substance onto a target surface, wherein said applicator has a first side, a second side, an internal cavity disposed between said first and second sides, at least one substantially fluid-impervious barrier layer disposed within said internal cavity adjacent at least one of said sides, a first product-containing flexible film reservoir comprising at least one non-laminated co-extruded film disposed adjacent said barrier layer, and a dispensing aperture associated with said reservoir through which said product is selectively distributed to one of said first and second sides, said method comprising the steps of:
- (a) providing a first web corresponding to one of said first and second sides;
- (b) providing a second web corresponding to the other of said first and second sides;
- (c) providing first product-containing reservoir in a predetermined location in relation to said first and second webs;
- (d) securing said reservoir relative to said first and second webs and attaching said first and second webs to one another in such a way as to form an internal cavity therebetween;
- and,
- (e) cutting said applicator in a desired outline shape from said attached first and second webs to define said applicator.
An applicator for distributing a product onto a target surface, said applicator comprising:
- (a) a first layer having a first face;
- (b) a second permeable layer having a first face;
- wherein said first face of said first layer and said first face of said second permeable layer are in a face-to-face relationship;
- and,
- (c) a product-containing non-laminated co-extruded film reservoir disposed adjacent either of said first layer or said second permeable layer;
- and,
- wherein said product is released to said target surface upon application of pressure to said reservoir.
