Liquid applicator

Abstract

Disclosed are liquid applicators for dispensing liquid to a surface such as a bathroom wall, and working the liquid against the surface. The applicators may have a compressible reservoir for the cleaning liquid. Upon compressing the reservoir the liquid is driven to a scrubbing pad in a controlled fashion. A check valve prevents back flow to the reservoir from the pad. A blister pack can house the scrubbing pad even when the pad is attached to the reservoir. In another form the applicator can be tipped and rested on its side between uses.

1 . A liquid applicator, comprising:
 a reservoir configured to hold a liquid to be applied to a surface, the reservoir having an adapter at one end;   the adapter comprising an opening extending axially there through and in communication with the reservoir, and a connection structure adjacent an outward end of the adapter; and   a pad removably engaged to the adapter;   wherein the pad comprises a layer attached to a mounting plate;   wherein the mounting plate has a connection structure suitable to engage the connection structure of the adapter; and   wherein the connection structures engage each other by a bayonet connection.   
   
   
       2 . The liquid applicator of  claim 1 , wherein the adapter connection structure is a leg, and the mounting plate connection structure is a groove. 
   
   
       3 . The liquid applicator of  claim 1 , wherein the adapter connection structure comprises two legs arrayed on opposing sides of the adapter opening at an outward end of the adapter, and the mounting plate connection structure comprises two arc form grooves, each with a widened portion and a narrowed portion. 
   
   
       4 . The liquid applicator of  claim 1 , wherein there is a one-way check valve in the adapter opening for permitting transfer of liquid from the reservoir past the adapter, but resisting return flow of liquid past the check valve to the reservoir. 
   
   
       5 . The liquid applicator of  claim 4 , further comprising a removable plug positionable downstream of the one-way check valve in the adapter opening. 
   
   
       6 . The liquid applicator of  claim 1 , wherein the liquid is a cleaning liquid. 
   
   
       7 . A liquid applicator, comprising:
 a reservoir configured to hold a liquid to be applied to a surface, the reservoir having an adapter at one end;   the adapter comprising an opening extending axially there through and in communication with the reservoir, and a connection structure adjacent an outward end of the adapter;   a pad removably engaged to the adapter; and   a well form pack suitable to receive the pad and house it prior to use;   wherein the pad comprises a layer attached to a mounting plate;   wherein the mounting plate has a connection structure suitable to engage the connection structure of the adapter; and   wherein the pad is configured so as to be suitable to be linked to the adapter while housed in the pack through a hole in a rearward wall of the pack, or alternatively be linked to the adapter when not housed in the pack.   
   
   
       8 . The liquid applicator of  claim 7 , further comprising a peel-off lid attached to the well form pack. 
   
   
       9 . The liquid applicator of  claim 8 , wherein the pad comprises a rearward sponge layer and a forward abrasive layer. 
   
   
       10 . The liquid applicator of  claim 8 , wherein the liquid is a cleaning liquid and the pad is a scrubbing pad. 
   
   
       11 . A liquid applicator, comprising:
 a reservoir configured to hold a liquid to be applied to a surface, the reservoir having an elongated upper handle and a side surface;   a scrubbing pad linked to a lower surface of the reservoir and configured to receive liquid there from; and   means associated with the reservoir to drive liquid out from the reservoir to the scrubbing pad;   wherein the applicator is suitable to be tipped so that its side surface is downwardly positioned, followed by the applicator being able to stably rest on the side surface when the side surface is placed on a horizontal support.   
   
   
       12 . The liquid applicator of  claim 11 , wherein the liquid is a cleaning liquid.
