Ready-to-use hose end sprayer

Abstract

A ready-to-use sprayer comprises a container defining an interior compartment for containing a liquid product and having a pin receiver located near the rear portion and an opening located near the front portion, a housing having a main chamber and a grip portion, a nozzle in selective fluid communication with the outlet of the fluid chamber, a pivot switch on the exterior of the housing for selecting a fluid flow condition for the main chamber, and the housing being coupled to the container at the container opening and the pin receiver.

1 . A sprayer comprising:
 a container defining an interior compartment for containing a substance liquid and comprising a pin receiver, the container comprising a front portion and a rear portion;   the pin receiver located proximate the rear portion;   a container opening located proximate the front portion;   a housing comprising a grip portion and a main chamber; and   the housing being coupled to the container at two separate points comprising: the container opening and the pin receiver.   
     
     
         2 . The sprayer of  claim 1 , wherein the front portion is elevated with respect to rear portion. 
     
     
         3 . The sprayer of  claim 1 , wherein the coupling at the pin receiver is effected using a pin inserted through the pin receiver. 
     
     
         4 . The sprayer of  claim 3 , wherein the pin is formed as part of the housing. 
     
     
         5 . The sprayer of  claim 3 , wherein the pin includes an outside portion that is perforated. 
     
     
         6 . The sprayer of  claim 3 , wherein the pin receiver receives the outside portion of the pin. 
     
     
         7 . The sprayer of  claim 1 , wherein the housing and the container are removably coupled through the pin and the pin receiver. 
     
     
         8 . The sprayer of  claim 1 , wherein the grip portion is curved and the main chamber comprises a substance liquid inlet, a carrier liquid inlet, and an outlet; and
 the housing further comprises: a carrier liquid receiving port and a nozzle in selective fluid communication with the outlet of the main chamber and the housing is coupled to the container opening at the substance liquid inlet.   
     
     
         9 . The sprayer of  claim 1 , wherein the housing further comprises:
 a pivot switch on the exterior of the housing for selecting a fluid flow condition for the main chamber, wherein the pivot switch is operatively coupled to a pivot arm to translate movement of the pivot switch, through an arcuate path, to the main chamber and the pivot arm is pivotally connected to a pivot axis, the pivot axis being located below the main chamber within the housing.   
     
     
         10 . The sprayer of  claim 9 , wherein the grip portion and the pivot switch are positioned so that a user can hold the sprayer and affect movement of the pivot switch with one hand. 
     
     
         11 . The sprayer of  claim 8 , further comprising:
 a carrier liquid conduit in selective fluid communication with the main chamber at the carrier liquid inlet;   a substance liquid conduit in selective fluid communication with the main chamber and the container at the substance liquid inlet.   
     
     
         12 . The sprayer of  claim 9 , wherein the pivot switch controls the flow of a carrier liquid and a substance liquid into the main chamber. 
     
     
         13 . The sprayer of  claim 11 , wherein the substance liquid conduit is positioned substantially perpendicular to the main chamber. 
     
     
         14 . The sprayer of  claim 11 , wherein the main chamber is configured to generate a vacuum to enable mixing of a carrier liquid and a substance liquid. 
     
     
         15 . The sprayer of  claim 1 , wherein the main chamber comprises:
 a rear chamber;   a middle chamber; and   a front chamber.   
     
     
         16 . The sprayer of  claim 15 , wherein the rear chamber, the middle chamber, and the front chamber have different dimensions. 
     
     
         17 . The sprayer of  claim 15 , wherein the main chamber is configured so that the mixing of a carrier liquid and a substance liquid occurs within the front chamber. 
     
     
         18 . The sprayer of  claim 15 , wherein the main chamber comprises three operating positions, the three operating positions comprising:
 a first operating position, wherein the main chamber is not in fluid communication with either a carrier liquid conduit or a substance liquid conduit;   a second operating position, wherein the main chamber is in fluid communication with both the carrier liquid conduit and the substance liquid conduit; and   a third operating position wherein the main chamber is fluid communication with the carrier liquid conduit but not with the substance liquid conduit.   
     
     
         19 . A sprayer comprising:
 a container defining an interior compartment for containing a substance liquid; the container comprising a front portion, a rear portion, and a pin receiver;   the pin receiver located proximate the rear portion;   a container opening located proximate the front portion;   a housing comprising:
 a curved grip portion, 
 a main chamber comprising a substance liquid inlet, a carrier liquid inlet, and an outlet, 
 a carrier liquid receiving port, and 
 a nozzle in selective fluid communication with the outlet of the main chamber; 
   a pivot switch having three operating positions, the pivot switch being located on the exterior of the housing for selecting a fluid flow condition for the main chamber, wherein the pivot switch is operatively coupled to a pivot arm to translate movement of the pivot switch, through an arcuate path, to the main chamber and the pivot arm is pivotally connected to a pivot axis, the pivot axis being located below the main chamber within the housing; and   the housing being coupled to the container at the container opening through the substance liquid inlet and at the pin receiver through a pin inserted through the housing and the pin receiver.
