Abstract

A plastic ampule dispenser for dispensing plastic ampules supplied in the form of strips of ampules connected together. The plastic ampule dispenser has an inclined guide plate for sliding a plurality of strips of plastic ampules, each strip being formed with cutlines between the adjacent plastic ampules, a plastic ampule stopper for stopping the plastic ampule at one end of the strip when the strip slides on and along the guide plate, and a separating device for separating the plastic ampule stopped at the head of the strip from the adjacent plastic ampule along the cutline therebetween.

a second stopper movable into and out of said ampule housing, wherein said second stopper supports the second lowermost one of said plurality of strips of plastic ampules when said second stopper is moved into said ampule housing,

wherein said first stopper and said second stopper move into and out of said ampule housing alternately so that one of said first and second stoppers is moved out of said ampule housing after the other of said first and second stoppers has been moved into said ampule housing and stopped.

8. The plastic ampule dispenser as claimed in claim 3, further comprising:

an ampule housing provided over said guide plate and being capable of storing a plurality of strips of plastic ampules; and

a discharge means for discharging the strips of plastic ampules, one by one, from the bottom of said ampule housing onto said guide plate.

9. The plastic ampule dispenser as claimed in claim 8, wherein said discharge means comprises:

a first stopper movable into and out of said ampule housing, wherein said first stopper supports the lowermost one of the plurality of strips of plastic ampules stored in said ampule housing when said first stopper is moved into said ampule housing;

a second stopper movable into and out of said ampule housing, wherein said second stopper supports the second lowermost one of said plurality of strips of plastic ampules when said second stopper is moved into said ampule housing,

wherein said first stopper and said second stopper move into and out of said ampule housing alternately so that one of said first and second stoppers is moved out of said ampule housing after the other of said first and second stoppers has been moved into said ampule housing and stopped.

10. The plastic ampule dispenser as claimed in claim 1, further comprising:

an ampule housing provided over said guide plate and being capable of storing a plurality of strips of plastic ampules, said ampule housing having a discharge passage on one side thereof; and

a pushing means for pushing the lowermost one of the plurality of strips of plastic ampules, stored in said ampule housing, into said discharge passage.

11. The plastic ampule dispenser as claimed in claim 10, wherein said pushing means comprises an arm provided under said ampule housing, said arm having a tip portion for engaging and pushing one side of the lowermost one of said strips of plastic ampules stored in said ampule housing upon rotation of said arm in one direction.
