   (c) at least one fluid dispensing conduit in fluid communication with said collapsible bag, extending through said base.   
     
     
         2 ) The device of  claim 1 , wherein said brush head further comprises: a plurality of bristles, said plurality of bristles having a distal end and a proximal end, wherein said distal end is attached to the base and said proximal end forms a skin contacting region. 
     
     
         3 ) The device of  claim 2 , wherein said plurality of bristles forms at least one flow path from said distal end towards said proximal end. 
     
     
         4 ) The device of  claim 3 , wherein said fluid dispensing conduit extends at least partway into said at least one flow path formed in said plurality of bristles. 
     
     
         5 ) The device of  claim 1 , further comprising a personal care composition contained within said collapsible bag. 
     
     
         6 ) The device of  claim 5 , wherein said personal care composition comprises at least one of a shaving preparation, a skin care composition, an antifungal composition, an antimicrobial composition, a wound healing composition, and an enzyme inhibiting composition. 
     
     
         7 ) The device of  claim 6 , wherein the personal care composition has a product form selected from the group consisting of gels, post foaming gels, creams, foaming and non-foaming liquids, mechanically pumpable liquids, non-aerosol gels, aerosol gels, aerosol foams, pastes, serums, and sprays 
     
     
         8 ) The device of  claim 6 , wherein said shaving preparation comprises a post foaming gel. 
     
     
         9 ) The device of  claim 1 , wherein the collapsible bag comprises at least one section having a wall thickness of less than about 100 micrometers. 
     
     
         10 ) The device of  claim 1 , wherein the collapsible bag has an open end and a closed end opposite said open end, and the elastically extensible band comprises a first end proximate the bag open end and a second end that is joined to the bag proximate the bag closed end. 
     
     
         11 ) The device of  claim 1 , wherein the elastic member is joined to the collapsible bag by at least one of an adhesive, a mechanical fastener, or a combination thereof. 
     
     
         12 ) The device of  claim 1 , wherein the elastic member exerts a hydrostatic pressure of between 135 and 480 kilopascals on the collapsible bag. 
     
     
         13 ) The device of  claim 1 , wherein at least 95% of the personal care composition disposed in the collapsible bag is dispensed when the product is operatively exhausted. 
     
     
         14 ) The device of  claim 1 , wherein the elastic member has a stretched length and an unstretched length, and the stretched length is at least 50% greater than the unstretched length. 
     
     
         15 ) The device of  claim 1 , wherein the collapsible bag includes a bag open end and a bag closed end, the article further comprising a valve member disposed in the bag open end, the valve member providing a flow path for the flowable composition to flow out of the collapsible bag. 
     
     
         16 ) The device of  claim 15 , wherein the valve member includes a rigid insert and a flexible body member operatively configured to provide an openable/closable flowpath through the valve member. 
     
     
         17 ) The device of  claim 16 , wherein the valve member includes a blind hole and at least one through hole passing through the side wall. 
     
     
         18 ) The device of  claim 17 , wherein the valve member forms two through holes diametrically opposed to one another forming a diametric orifice. 
     
     
         19 ) The device of  claim 1 , further comprising a depressible button 
     
     
         20 ) A device for dispensing a personal care product onto skin comprising:
 (a) a brush head comprising a base, and   (b) a device body operatively connected to said brush head about said base, said device body comprising:
 (i) an outer container; 
 (ii) an at least partially expanded collapsible bag disposed in the outer container, an elastic member surrounding at least a portion of the collapsible bag such that the elastic member is stretched axially and radially, the elastic member being constructed of rubber; 
   (c) at least one fluid dispensing conduit in fluid communication with said collapsible bag, extending through said base,   (d) wherein the collapsible bag has an open end and a closed end opposite said open end, and the elastically extensible band comprises a first end proximate the bag open end and a second end that is joined to the bag proximate the bag closed end   (e) wherein the personal care composition is a shave preparation in the form of a non-aerosol gel.
