Abstract
The feed duct of a tablet dispenser is formed with a movable wall portion which engages a tablet next adjacent the tablet being dispensed to prevent more than a single tablet from being dispensed at a time. A dispenser slide which opens and closes the discharge opening of the feed duct actuates displacement of the movable wall portion through an interposed spring member. Another movable wall portion of the feed duct located further upstream may operate in tandem with the first wall portion to block the feed duct and thereby prevent backward movement of tablets within the feed duct while the discharge opening is closed.
Claims7
A tablet dispenser comprising:
- wall means defining a feed duct dimensioned to permit passage therethrough in a given direction of tablets to be dispensed by said tablet dispenser, said feed duct being defined with a discharge opening at one end thereof;
- slide means movable to open and close said discharge opening to enable selective dispensing of tablets therefrom;
- clamping means operable to prevent movement within said duct means in said given direction of tablets located beyond a predetermined distance upstream of said discharge opening, said clamping means comprising a portion of said wall means adapted to be displaced inwardly of said duct means;
- spring means operably engaged between said slide means and said portion of said wall means to effect displacement of said portion inwardly of said duct means when said slide means is moved to open said discharge opening;
- and holding means located along said duct means further upstream than said clamping means operable when said discharge opening is closed by said slide means to prevent within said duct means reverse movement of said tablets in a direction upstream of said given direction, said holding means being operably connected with said slide means for movement out of its effective position when said discharged opening is opened.
A tablet dispenser comprising:
- wall means defining a feed duct dimensioned to permit passage therethrough in a given direction of tablets to be dispensed by said tablet dispenser, said feed duct being defined with a discharge opening at one end thereof;
- slide means movable relative to said wall means to open and close said discharge opening of said feed duct defined by said wall means to enable selective dispensing of tablets therefrom;
- clamping means operable to prevent movement within said duct means in said given direction of tablets located beyond a predetermined distance upstream of said discharge opening, said clamping means being comprised of a portion of said wall means adapted to be displaced inwardly of said duct means;
- and spring means operably engaged between said slide means and said portion of said wall means comprising said clamping means to effect displacement of said portion inwardly of said duct means to actuate said clamping means to prevent movement of said tablets through said duct means past said clamping means toward said discharge opening when said slide means is moved to open said discharge openings;
- said wall means being structured separately from said slide means and being arranged to define said duct means at least between said opening and said clamping means with a fixed width dimension sized approximately equivalent to the width of a single tablet to be dispensed to pass said tablets between said clamping means and said opening in a single tablet row one behind the other.
