Abstract
This invention relates to disposable swab articles and other like packages comprising an applicator package having distal ends and having a foam applicator pad and a backing member adjacent thereto. The backing member has at least one reservoir and being formed of a relatively rigid, flat sheet material and a formed material for containing the contents of the reservoir therebetween. The flat sheet material has a slit or weakened portion in the surface of the material and the slit or weakened portion is transversely disposed of the flat sheet material, so that the slit or weakened portion is ruptured upon forcing the distal ends toward each other about the slit or weakened portion. The contents of the reservoir are thereby released into the foam applicator pad upon pressure deforming the formed material containing the reservoir.
Claims8
An applicator package having distal ends comprising a foam applicator pad and having a backing member adjacent thereto:
- said backing member being formed of a relatively rigid, flat and stiff plastic sheet material having a vapor and gas barrier coating and a laminated deformable plastic coated foil material having at least one reservoir containing a flowable product, such as a liquid being sealed to said flat and stiff sheet material for containing the contents of said reservoir therebetween;
- said flat and stiff sheet material having a centrally disposed linear weakened portion in the surface of said flat and stiff sheet material and said weakened portion being transversely disposed of said flat and stiff sheet material with said foam applicator pad secured to the outer surface of said flat and stiff sheet material and centrally disposed over said weakened portion;
- said weakened portion rupturing upon forcing said distal ends of said applicator package towards each other and about said weakened portion, so as to compress the reservoir of said deformable plastic coated foil material by crushing opposite sides of said reservoir against each other such that substantially all of said flowable product in the reservoir can be controllably released into said applicator pad for wiping applications upon pressure completely deforming and collapsing said plastic coated foil material;
- and said foam applicator pad is a foam block having opposite slits partially through said foam block so that when said distal ends are squeezed together, the foam block assumes an inverted T-shape with a large wiping contact surface area.
