Abstract

A system for dispensing presaturated wiper sheets for use in various industrial and manufacturing situations includes a reusable dispenser canister and at least one refill package of wiper sheets. The dispensing canister may include a receptacle base, and a lid threaded onto the base. A gasket, such as an annular disc of compressible foam material, may be interposed between the base and lid. The lid includes an integral cap unit which defines a storage well and a cap element. An aperture, through which a portion of the leading sheet extends, is defined in a bottom portion of the storage well. The well is preferably deep enough so that the wiper portion can be relatively long, without interfering with closing of the cap element. The cap unit is designed to provide a relatively tight seal when the cap element is closed. A lip protrudes up at an acute angle from a main cap portion of the cap element to facilitate opening of the cap element, even by a gloved worker.

Claims

1. A presaturated wiper assembly comprising:

a plurality of wiper sheets connected together in a continuous length such that individual sheets thereof can be pulled apart from said continuous length by a user, said wiper sheets being presaturated with a predetermined solvent;

a container having a base and a lid attached to said base;

said base defining a receptacle containing said plurality of wiper sheets;

said lid defining an aperture having a portion of a leading wiper sheet in said continuous length extending therethrough, said lid further including a cap element having a main cap portion closeable to cover said aperture and openable to expose said portion of said leading wiper sheet; and

an annular gasket interposed between said base and said lid, wherein said aperture is defined in a bottom portion of a lid well, said cap element and said lid well being constructed as an integral unit fixedly attached to said lid, wherein said main cap portion of said cap element has a hinge and a protruding lip located on opposite sides thereof, and wherein said main cap portion carries a depending seal ring, said seal ring engaging an annular protrusion defining a pair of sloped surfaces converging to an apex on said inner surface of said lid well to provide a seal when said main cap portion is closed.

2. A presaturated wiper assembly comprising:

a plurality of wiper sheets connected together in a continuous length such that individual sheets thereof can be pulled apart from said continuous length by a user, said wiper sheets being presaturated with a predetermined solvent;

a container having a base and a lid attached to said base;

said base defining a receptacle containing said plurality of wiper sheets;

said lid having a lid well defining an aperture having a portion of a leading wiper sheet in said continuous length extending therethrough;

said lid further including a cap element having a main cap portion closeable to cover said aperture and openable to expose said portion of said leading wiper sheet; and

said main cap portion of said cap element carrying a depending seal ring, said seal ring engaging an annular protrusion defining a pair of sloped surfaces converging to an apex on said inner surface of said lid well to provide a seal when said main cap portion is closed.

3. A presaturated wiper assembly as set forth in claim 2, wherein said main cap portion has a hinge and a protruding lip located on opposite sides thereof.

4. A presaturated wiper assembly as set forth in claim 3, wherein said protruding lip extends up from said cap element at an acute angle.

5. A presaturated wiper assembly as set forth in claim 2, wherein said cap element and said lid well are constructed as an integral unit fixedly attached to said lid.

6. A presaturated wiper assembly as set forth in claim 5, wherein said lid well has a depth of at least approximately 0.3 inch.

7. A presaturated wiper assembly as set forth in claim 2, further comprising a gasket interposed between said base and said lid.
