Abstract
The present invention is directed to a foam soap delivery system. In accordance with the present invention, the system includes a paperboard core with a plurality of sheets of paper or tissue wound around the paperboard core. A dispenser is removably disposed within the paperboard core, and a water-soluble sheet soap is disposed within the dispenser.
Claims68
A foam soap delivery system comprising:
- a) a paperboard core comprising a first distal end and a second distal end;
- b) a plurality of sheets of a paper or a tissue wound around the paperboard core;
- c) a dispenser removably disposed within the paperboard core;
- d) a water-soluble sheet soap disposed within the dispenser, the sheet soap being dissolvable in water to form a foamable solution, the sheet soap having a bending resistance in a range between about 1 milligram-force (mgf) and about 50 mgf as measured by Technical Association of the Pulp and Paper Industry (TAPPI) test method T 543 om-11;
- e) the sheet soap comprising a contact product of polyvinyl alcohol, at least one film-forming material, an ionic cross-linker composition, and a surfactant composition, the polyvinyl alcohol, the at least one film-forming material, and the ionic cross-linker composition defining a film-forming composition, the film-forming composition being present in a range between about 20% and about 50% by weight of the total weight of the sheet soap, the polyvinyl alcohol being present in the film-forming composition in a range between about 5% and about 60% by weight of the total weight of the sheet soap, and the ionic cross-linker composition being present in the film-forming composition in a range between about 1% to about 10% by weight of the total weight of the sheet soap;
- and
- f) the dispenser discharging a foam upon stimulation by a user when water is present within the dispenser.
