Center-Pull Dispenser for Web Material

Abstract

According to one exemplary embodiment of the present invention, a center-pull bottom feed dispenser includes a housing defining a compartment and including a center-pull bottom feed arrangement for dispensing a sheet material that is in the form of a roll of the sheet material. The sheet material can be a pre-moistened airlaid web. The dispenser also includes a tray that supports the airlaid web roll and includes an outlet opening through which the airlaid web is fed to be accessible to a user. The tray includes a moisture retaining feature that directs fluid from the pre-moistened air-laid web away from the outlet opening and toward an outer peripheral edge of the roll.

1 . A center-pull bottom feed dispenser comprising:
 a housing defining a compartment and including a center-pull bottom feed arrangement for dispensing a sheet material, the compartment capable of enclosing a roll of the sheet material which comprises a pre-moistened web material; and   a tray disposed in a lower portion of the compartment, the tray capable of supporting the roll, the tray including an outlet opening through which a lead sheet of the web material is fed to be accessible to a user, wherein a support surface on which the roll is supported has a negative slope as measured from a center portion to an outer peripheral edge of the tray, the roll being orientated on the support surface so that any fluid within the pre-moistened web that is pulled downward toward the support surface due to gravitational forces flows radially outward from the center portion toward the outer peripheral edge to prevent the fluid from dripping out of the outlet opening and to make the fluid available for reabsorption into the roll of web material.   
     
     
         2 . The dispenser of  claim 1 , wherein the pre-moistened web contains an antiseptic agent. 
     
     
         3 . The dispenser of  claim 2 , wherein the antiseptic agent is an alcohol. 
     
     
         4 . The dispenser of  claim 1 , wherein the pre-moistened web contains a disinfectant. 
     
     
         5 . The dispenser of  claim 4 , wherein the disinfectant comprises a quaternary compound selected from the group consisting of (1) benzalkonium chlorides; (2) substituted benzalkonium chlorides; (3) di(C6-C14)alkyl di short chain (C1-4 alkyl and/or hydroxyalkl) quaternary; (4) N-(3-chloroallyl) hexaminium chlorides; (5) benzethonium chloride; (6) methylbenzethonium chloride; (7) cetylpyridinium chloride; (8) di(C6-C14)dialkyl dimethyl ammonium chloride; (9) dialkyldimethylammonium chlorides, (10) alkyldimethylbenzylammonium chlorides; (11) dialkylmethylbenzylammonium chlorides; (12) diisobutylphenoxyethoxyethyl dimethylbenzylammonium chloride; and (13) (methyl)diisobutylphenoxyethoxyethyl dimethylbenzylammonium chloride (i.e. methylbenzethonium chloride). 
     
     
         6 . A center-pull top feed dispenser comprising:
 a housing defining a compartment and including a center-pull top feed arrangement for dispensing a sheet material;   a roll of the sheet material which comprises a pre-moistened web that contains an antiseptic agent or a disinfectant; and   a container for holding the roll of sheet material such that the container forms a fluid barrier and contains the antiseptic agent or the disinfectant.   
     
     
         7 . The dispenser of  claim 6 , wherein the disinfectant comprises a quaternary compound selected from the group consisting of (1) benzalkonium chlorides; (2) substituted benzalkonium chlorides; (3) di(C6-C14)alkyl di short chain (C1-4 alkyl and/or hydroxyalkl) quaternary; (4) N-(3-chloroallyl) hexaminium 30 chlorides; (5) benzethonium chloride; (6) methylbenzethonium chloride; (7) cetylpyridinium chloride; (8) di(C6-C14)dialkyl dimethyl ammonium chloride; (9) dialkyldimethylammonium chlorides, (10) alkyldimethylbenzylammonium chlorides; (11) dialkylmethylbenzylammonium chlorides; (12) diisobutylphenoxyethoxyethyl dimethylbenzylammonium chloride; and (13) (methyl)diisobutylphenoxyethoxyethyl dimethylbenzylammonium chloride (i.e. methylbenzethonium chloride). 
     
     
         8 . The dispenser of  claim 6 , wherein the antiseptic agent is alcohol. 
     
     
         9 . The dispenser of  claim 6 , wherein the pre-moistened web is an airlaid material comprising cellulosic fibers and a binder. 
     
     
         10 . The dispenser of  claim 9 , wherein the binder comprises a latex, bicomponent fiber, or latex and bicomponent fiber. 
     
     
         11 . The dispenser of  claim 6 , wherein the container includes a sealable opening that permits the sheet of material to be fed there through in an unsealed condition. 
     
     
         12 . The dispenser of  claim 6 , wherein the container is formed of a substantially flexible material to permit the shape of the container to be conformed to a shape of the compartment. 
     
     
         13 . The dispenser of  claim 12 , wherein the container comprises a plastic bag. 
     
     
         14 . The dispenser of  claim 6 , wherein the container comprises a cartridge that is insertable into the compartment of the housing.
