Abstract
Abstract A sheet assembly for polishing work is provided. A non-woven fabric sheet and a non-permeable thick sheet are bonded together to define a first chamber. Further, a second chamber to contain a shoe polish therein is defined within said first chamber by a non-permeable but easily rupturable film such as a polyethylene sheet. The non-woven fabric sheet or the non-permeable thick sheet is formed with apertures therein. The shoe polish contained in the second chamber is discharged therefrom and further through the apertures to the outside of the sheet assembly when manually pressed from outside such that the shoe polish is ready for application onto shoes such that the shoes are shined by use of the non-woven fabric portion.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
151 words
A sheet assembly for polishing work comprising: first sheet means having a generally planar structure and defining a first chamber therein; second sheet means provided in said first chamber for defining a second chamber therein in an air-tightly sealed condition, said first sheet means and said second sheet means being bonded together to define a dispersion chamber therebetween; and a polishing composition filled in said second chamber, said second sheet means being formed of a plastic material rupturable when said seond chamber is manually applied with force from outside the dispersion chamber to discharge said polishing composition into the dispersion chamber in a dispersed manner, said first sheet means having at least one aperture comprising an outlet from said dispersion chamber and located at a position remote from the second chamber for further discharging said polishing composition out of the dispersion chamber when further pressed from outside the dispersion chamber manually.
Claim 2
Dependent Claim
