Description
- The present invention relates to the distribution of cleanroom wipes and, more particularly, to a dispenser that prevents wasteful usage and eliminates cross contamination of cleanroom wipes.
- Within particular industries, such as pharmaceuticals, biomedical, micro-electronics and the like, it is imperative that exposure to microbial contaminants, electrostatic discharge (ESD) and the like are minimized at every turn of the manufacturing process and in and around the workspace, such as a cleanroom, where they are manufactured and handled. As a result, the use of cleanroom wipes within such workspaces and associated cleanrooms is vital in implementing this imperative.
- However, it is human nature for people to use more wipes than necessary, especially when they are not paying for them. This is especially a problem in cleanrooms where cleanroom wipes are extremely expensive and typically stacked in a pile. All too frequently, cleanroom workers will take many more wipes than the one wipe that is needed. And they usually “fan” through the top twenty or more sheets then take two or more. This typical behavior not only wastes wipes, but cross contaminates the “fanned” wipes, which is hazardous to good manufacturing practices, particularly when the cleanroom is manufacturing pharmaceuticals, biomedical or organ transplantation tissues and materials. Another problem is that cleanroom wipes are typically sitting on a bench, or cart exposed to the environment, susceptible to environmental contamination. Furthermore, they are sitting in plain non ESD bags that contain static electricity, which is harmful to a cleanroom that produces microelectronics.
- As can be seen, there is a need for a dispenser that prevents wasteful usage and eliminates cross contamination of cleanroom wipes.
- In one aspect of the present invention, a cleanroom wipe dispenser comprises: a housing having a plurality of walls that form a compartment; a generally elongated elliptical shaped dispensing opening defined by at least one of the plurality of walls; and a plurality of cleanroom wipes stored within the compartment, each comprising a sheet uniquely folded in an “C” shape defining an upper leg and a lower leg, and wherein the lower leg of each cleanroom wipe abuts the upper leg of an adjacent cleanroom wipe, so that each cleanroom wipe abrades the adjacent cleanroom wipe when dispensed through the dispensing opening.
- In another aspect of the present invention, method of preventing cross contamination of cleanroom wipes comprises: providing a housing having a plurality of walls that form a compartment; and a generally elongated elliptical shaped dispensing opening defined by at least one of the plurality of walls; folding a plurality of cleanroom wipes, wherein each cleanroom wipe is a sheet uniquely folded in a “C” shape defining an upper leg and a lower leg, and wherein the lower leg of each cleanroom wipe abuts the upper leg of an adjacent cleanroom wipe so that each cleanroom wipe abrades the adjacent cleanroom wipe when dispensed through the dispensing opening; and storing the plurality of cleanroom wipes within the compartment.
- These and other features, aspects and advantages of the present invention will become better understood with reference to the following drawings, description and claims.
