Abstract

Abstract A liquid applicator for applying a desired liquid to a surface includes a closed ampule formed of a fracturable material containing the desired liquid, a body having a pocket with an open side and a shape adapted to receive the ampule, and a porous element sealed to the body and closing off the open side of the pocket so that liquid flows through the element when the ampule is fractured. The body includes a pair of side walls that are spaced from one another in a first direction to define the pocket, and a pair of gripping members, are provided, which can be pivoted to fracture the ampule during use. The porous element is laminated with a material that does not stretch in the first direction, and the laminate material is secured between the side walls of the body to define a structural insert that prevents the side walls from pulling apart from one another when the gripping members are pivoted.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 148 words
A liquid applicator comprising: a body including a pair of side walls that are spaced from one another in a first direction to define a pocket; a closed ampule received in the pocket, the ampule being formed of a fracturable material and containing a liquid to be dispensed; a lever presenting a first end secured to one of the side walls, a second free end, and an intermediate tappet that bears against the body and fractures the ampule when the lever is pivoted; and a porous element covering the pocket so that liquid flows through the porous element when the ampule is fractured, the porous element being laminated with a material that does not stretch in the first direction, the laminate material being secured directly to the side walls of the body to prevent the side walls from pulling apart from one another when the lever is pivoted.
Claim 2
Dependent Claim 148 words
A liquid applicator comprising: a body including a pair of side walls that are spaced from one another in a first direction to define a pocket; a closed ampule received in the pocket, the ampule being formed of a fracturable material and containing a liquid to be dispensed; a lever presenting a first end secured to one of the side walls, a second free end, and an intermediate tappet that bears against the body and fractures the ampule when the lever is pivoted; and a porous element covering the pocket so that liquid flows through the porous element when the ampule is fractured, the porous element being laminated with a material that does not stretch in the first direction, the laminate material being secured directly to the side walls of the body to prevent the side walls from pulling apart from one another when the lever is pivoted.
Claim 3
Dependent Claim 36 words
A liquid applicator as recited in claim 1, wherein the body is elongated, defining a longitudinal axis extending transverse to the first direction, the laminate material of the porous element being stretchable along the longitudinal axis.
Claim 4
Dependent Claim 15 words
A liquid applicator as recited in claim 2, wherein the laminate material is a fabric.
Claim 5
Dependent Claim 16 words
A liquid applicator as recited in claim 2, wherein the laminate material is a polyester fabric.
Claim 6
Dependent Claim 34 words
A liquid applicator as recited in claim 1, wherein the ampule is formed of glass and the laminate material of the porous element resists puncture by fragments of the glass from the fractured ampule.
Claim 7
Dependent Claim 51 words
A liquid applicator as recited in claim 1, wherein levers are secured to both side walls, each lever including a first end secured to one of the side walls, a second free end, and an intermediate tappet that bears against the body and fractures the ampule when the lever is pivoted.
Claim 8
Dependent Claim 29 words
A liquid applicator as recited in claim 1, wherein the laminate material and the material of the body are melted together to secure the porous element to the body.
