Dispenser for moist wipe material, a web of material for use therein and fluted roller

摘要

A dispenser for moist wipe material comprises a support member carrying a holder for a supply of material, a reservoir for a moistening fluid, a tank for dispensing moistening fluid into the fluid reservoir to maintain a desired level of fluid therein, a first roller disposed in the reservoir and having a first surface region dipping into the reservoir to a depth below said level, a means for driving the first roller to transport moistening fluid from the reservoir to material contacting a second surface region of the first roller spaced from said first region and a second roller for pressing the web of material onto the first roller. In this design a section of said material overlies an opening in a wall of said reservoir and contacts said second surface region and said second roller is disposed in a housing adapted to seal against said wall of said reservoir around said opening with said second roller pressing said section of material into contact with said second surface region and said material being engaged by said housing and said wall upstream and downstream of said opening with a force permitting the transport of said material between said housing and said wall on driving of said first roller. A web of material having cut-outs and a special design of fluted roller are also claimed.

1. A dispenser for dispensing moistened material, the dispenser comprising a support member carrying a holder for a supply of the material, a reservoir for a moistening fluid, a tank for dispensing moistening fluid into the fluid reservoir to maintain a desired level of fluid therein, a first roller disposed in the reservoir and having a first surface region dipping into the reservoir to a depth below said level, a means for driving the first roller to transport moistening fluid from the reservoir to material contacting a second surface region of the first roller spaced from said first region and a second roller for pressing some of the material onto the first roller,
wherein, in use of the dispenser, a section of said material overlies an opening in a wall of said reservoir and contacts said second surface region and said second roller is disposed in a housing adapted to seal against said wall of said reservoir around said opening with said second roller pressing said section of material into contact with said second surface region and said material being engaged by said housing and said wall upstream and downstream of said opening with a force permitting the transport of said material between said housing and said wall on driving of said first roller, further wherein said first roller is a fluted roller having longitudinal grooves or flutes arranged at regular angular intervals around the roller and the longitudinal grooves or flutes extend generally in parallel to an axis of the fluted roller with adjacent grooves or flutes merging into one another at longitudinal peaks of the fluted roller, with each groove or flute being of generally arcuate shape at its base between each adjacent pair of peaks, wherein the second roller has a shape substantially complementary to that of the first roller and wherein the first roller and the second roller is arranged such that the longitudinal peaks of the flutes of the first roller and bases of the corresponding flutes of the second roller are aligned when the first roller and the second roller are rotating to prevent wicking of the fluid.
