Abstract
A wiper assembly for use in cleansing a controlled environment. The assembly comprises a generally flat container having therein a plurality of wiper cloths presaturated with a selected cleaning or disinfectant solvent. A top portion of the container defines an opening for wiper cloth removal which may be selectively opened and closed using a flexible adhesive panel. The bottom portion of the container is characterized by a greater rigidity than the rigidity of the top portion. This enhanced rigidity is sufficient to substantially prevent bending of the container during removal of the wiper cloths and closure of the container opening.

A presaturated wiper assembly for use in cleansing a controlled environment, said assembly comprising:
- a generally flat container having a top portion and a bottom portion each comprising a polymeric sheet, said top portion disposed on an opposite side from said bottom portion of a plane substantially including a circumference of said container at which said top portion meets said bottom portion to define an interior cavity between said top portion and said bottom portion;
- said top portion further defining a container opening for access to said interior cavity;
- a panel having a pivot portion secured to said top portion and a foldable closure portion extending therefrom, said closure portion removably engaging said top portion to permit selective closure of said container opening;
- a plurality of wiper cloths located in said interior cavity and forming a stack, said stack deforming said top portion and said bottom portion respectively away from said plane;
- cleaning solution located in said interior cavity to substantially saturate said plurality of wiper cloths;
- and
- one of said bottom portion and said top portion having a first rigidity greater than a second rigidity of the other of said top portion and said bottom portion, said first rigidity being sufficient to substantially prevent bending of said container during removal of said wiper cloths and closure of said container opening.
A presaturated wiper assembly for use in cleansing a controlled environment, said assembly comprising:
- a generally flat container having a top portion and a bottom portion each comprising a polymeric sheet, said top portion disposed on an opposite side from said bottom portion of a plane substantially including a circumference of said container at which said top portion meets said bottom portion to form an interior cavity between said top portion and said bottom portion;
- said top portion including a foldable flap to define a container opening for access to said interior cavity;
- a panel having a pivot portion secured to said top portion and a foldable closure portion overlying said flap, said closure portion having an adhesive area for removably engaging said top portion;
- a wiper cloth stack located in said interior cavity and deforming said top portion and said bottom portion respectively away from said plane;
- cleaning solution located in said interior cavity to substantially saturate wiper cloths in said wiper cloth stack;
- and
- said container also including a rigidity mechanism associated with at least one of said top portion and said bottom portion, said rigidity mechanism configured to substantially prevent bending of said container during removal of said wiper cloths and closure of said container opening, even if said wiper cloth stack is substantially depleted.
