Pop-up wipes dispensing system for substantially dry wipes

Abstract

Pop-up dispensing systems for dispensing substantially dry wipes while minimizing “clumping” and “fallbacks”, or sticking of tacky, adhesive binder loaded wipes within the interior of the container body. The dispensing system includes a container having a container body forming an interior region, and a plurality of stacked substantially dry wipes or other substrates. The wipes may be loaded with an adhesive binder or other material. By selecting and providing particular characteristics relative to the cross-sectional area of the dispensing orifice (e.g., 22 cm 2 to 75 cm 2 ) and the separation force profile (e.g., 1 gf/cm 2 to 6 gf/cm 2 ), wipes which are loaded with an adhesive, tacky binder material can be dispensed one at a time, while minimizing clumping and fallbacks, and any tendency of the wipes to becoming stuck within the container body.

         16 . The pop-up dispensing system of  claim 11 , wherein the container is rectangular and includes a folding cover panel different from the upper panel, the cover panel folding over the dispensing orifice of the upper panel, acting as a lid so as to protect the wipes during storage.
