Abstract

A device for dispensing a controlled quantity of a product comprising a housing having a dispensing member movable therein, a dispensing cavity being extendable exteriorly of the housing to permit dispensing of a single unit, a single locking device to lock the dispensing member within the housing, and a second locking arrangement to prevent the dispensing member from being pushed rewardly from the housing, the second locking arrangement comprising first and second locking members which extend outwardly form the dispensing member to engage the housing, the first and second locking members being arrangement such that pressure on one of the locking members to release the same result in a tighter engagement of the other of the locking members with housing.

1 . A device for dispensing a controlled quantity of a product comprising:
 a housing;   a dispensing member having a dispensing cavity formed therein, said dispensing member being movable from a first position wherein said dispensing cavity is rendered inaccessible within said housing and a second dispensing position wherein said dispensing cavity is exterior of said housing to permit dispensing of a product therefrom;   a single locking means to lock said dispensing member within said housing; and   second locking means to prevent said dispensing member from being pushed rearwardly from said housing, said second locking means comprising first and second locking members extending outwardly from said dispensing member to engage said housing, said first and second locking members being arranged such that pressure on one of said locking members to release the same results in a tighter engagement of the other of said locking members with said housing.   
   
   
       2 . The device of  claim 1  wherein said housing is in the form of a sleeve and said moveable member has first and second opposed ends, said first end extending exteriorly of said sleeve when in said first position, said second end having said dispensing cavity located therein, the arrangement being such that finger pressure may be applied to said first end to slidably move said dispensing member to said second position. 
   
   
       3 . The device of  claim 2  wherein said dispensing cavity is sized to receive a single unit of said product therein. 
   
   
       4 . The device of  claim 3  wherein said dispensing member has a product storage cavity located proximate said first end, a channel extending between said product storage cavity and said dispensing cavity, said channel being sized to permit the passage of a signal unit of said product. 
   
   
       5 . The device of  claim 2  wherein said housing and said dispensing member are formed of an injection molded plastic. 
   
   
       6 . The device of  claim 1  further including biasing means biasing said dispensing member towards said first position. 
   
   
       7 . The device of  claim 1  wherein said single locking means to lock said dispensing member within said housing comprises a flexible locking tab mounted on said dispensing member, an aperture formed in said sleeve, said flexible tab member having a raised portion thereto engage said aperture when in said first locked position, said tab member, when depressed, permitting movement of said dispensing member to said second dispensing position.
