Dispensing device

Abstract

A device for dispensing fluid for use as an eyewash station comprising a flexible container for containing said fluid, a reservoir attached externally to said container, a conduit housed within said container in fluid communication with said reservoir, and a sealing means to prevent passage of said fluid from said container through said reservoir prior to initial use of said device. The device is adapted such that, upon breakage of said sealing means, said fluid can pass through said conduit to said reservoir when said flexible container is flexed inwards by a user of said device.

1 . A device for dispensing fluid, said fluid of use as an eyewash, said device including: 
 a flexible container for containing said fluid;    a reservoir attached externally to said container;    a conduit housed within said container in fluid communication with said reservoir; and    a sealing means to prevent passage of said fluid from said container through said conduit to said reservoir prior to initial use of said device;    said device adapted such that, upon breakage of said sealing means, said fluid can pass through said conduit to said reservoir when said flexible container is flexed inwards by a user of said device.    
     
     
         2 . A device as defined in  claim 1 , wherein said container and said reservoir are adapted so that said reservoir can be moved from a first non-use position to a second in-use position.  
     
     
         3 . A device as defined in  claim 2 , wherein, said reservoir includes a piercing means adapted to pierce said sealing means when said reservoir moves to said second position.  
     
     
         4 . A device as defined in  claim 3 , wherein said piercing means is an extension from the base of said reservoir, said extension being sufficiently tapered to pierce said sealing means as said reservoir is moved to said second in-use position.  
     
     
         5 . A device as defined in  claim 1 , wherein said reservoir includes at least one first aperture, each said first aperture being adapted to prevent said fluid from returning from said reservoir to said container.  
     
     
         6 . A device as defined in  claim 1 , wherein said reservoir includes a plurality of second aperatures, said second aperatures adapted to provide a spray effect for said formulation as said formulation passes from said container to said reservoir.  
     
     
         7 . A device as defined in  claim 1 , wherein an inner cap is removably affixed to the neck of said container, said inner cap incorporating said conduit and wherein said reservoir is removable affixed to said inner cap.  
     
     
         8 . A device as defined in  claim 7 , wherein said inner cap and said reservoir are further adapted to provide a stop means to initially securely position said reservoir in said first non-use position and then to securely maintain said reservoir in said second in-use position when said device is in use.  
     
     
         9 . A device as defined in  claim 8 , wherein said stop means includes: 
 an external ridge positioned at or near the lower portion of said reservoir;    a first recess around the exterior surface of said inner cap at or near its lower end; and    a second recess around said exterior of said inner cap at approximately its mid-length;    wherein said external ridge is of a complementary shape to each of said first recess and said second recess.    
     
     
         10 . A device as defined in  claim 1 , wherein said device further includes a cap adapted to be detachably affixed to, and cover, said reservoir.
