Abstract

An ampule dispenser is capable of discharging ampules stored in a random manner one by one after arranging them in an orderly manner. A hole is formed in the bottom plate of an ampule housing. The bottom plate has a top surface sloping downward toward this hole. A push-up member adapted to be moved up and down through the hole has an ampule supporting portion on which a single ampule is placed at a time in a laid-down position. By moving the push-up member upward, the ampule supported on its supporting portion is raised to the highest position, where it slides down the sloping supporting portion and is discharged through a discharge port formed in the peripheral wall of the ampule housing.

Claims

1. An ampule dispenser comprising:

an ampule housing for housing a plurality of ampules in a disorganized manner, said ampule housing comprising a bottom plate having an edge and a hole in said bottom plate near said edge, said bottom plate sloping downward toward said hole, and a peripheral wall having a take-out port therein located above said hole in said bottom plate;

a push-up member received in said hole of said bottom plate such that said push-up member can move up and down through said hole, said push-up member having an ampule supporting portion on a top surface thereof capable of supporting only one ampule at a time in a laid-down position and sloping downward toward said take-out port when said push-up member is in an upper position, whereby ampules can be lifted one by one from said housing and discharged through said take-out port;

a container smaller than said housing connected to said take-out port, said container having a bottom plate sloping downward in an ampule discharge direction, said bottom plate having a lowest end and a hole at said lowest end, and a peripheral wall having a discharge port and a sloping chute connected with said discharge port; and

a second push-up member received in said hole of said container such that said second push-up member can move up and down in said hole of said container, said second push-up member having an ampule supporting portion capable of supporting only one ampule at a time in a laid-down position, said ampule supporting portion of said second push-up member sloping in the same direction as said bottom plate of said container, and said ampule supporting portion of said second push-up member having a highest position in which said ampule supporting portion of said second push-up member is located opposite to said discharge port.

2. The dispenser of claim 1, and further comprising a plurality of sensors for detecting ampules on said bottom plate of said container and a control means for stopping said push-up member of said ampule housing if at least two of said plurality of sensors separately detect ampules on said bottom plate of said container.

3. The dispenser of claim 2, and further comprising a stirrer in said ampule housing for stirring ampules near said push-up member.

4. The dispenser of claim 3, wherein said stirrer comprises a stirring member extending through said bottom plate of said ampule housing near said push-up member and capable of moving up and down through said bottom plate.

5. The dispenser of claim 2, wherein said ampule housing comprises a pair of guide surfaces on side walls on opposite sides of said push-up member for guiding ampules toward said hole formed in said bottom plate of said ampule housing.

6. The dispenser of claim 5, wherein said guide surfaces are displaced relative to each other in the direction in which said bottom plate of said ampule housing slopes.

7. The dispenser of claim 1, and further comprising a stopper movable between one position in which said stopper protrudes into said sloping chute for stopping an ampule in said chute and another position in which said sloping chute is unblocked.

8. The dispenser of claim 1, and further comprising a stirrer in said ampule housing for stirring ampules near said push-up member.

9. The dispenser of claim 8, wherein said stirrer comprises a stirring member extending through said bottom plate of said ampule housing near said push-up member and capable of moving up and down through said bottom plate.

10. The dispenser of claim 1, wherein said ampule housing comprises a pair of guide surfaces on side walls on opposite sides of said push-up member for guiding ampules toward said hole formed in said bottom plate of said ampule housing.

11. The dispenser of claim 10, wherein said guide surfaces are displaced relative to each other in the direction in which said bottom plate of said ampule housing slopes.

12. An ampule dispenser comprising:

an ampule housing for housing a plurality of ampules in a disorganized manner, said ampule housing comprising a bottom plate having an edge and a hole in said bottom plate near said edge, said bottom plate sloping downward toward said hole, and a peripheral wall having a take-out port therein located above said hole in said bottom plate;

a push-up member received in said hole of said bottom plate such that said push-up member can move up and down through said hole, said push-up member having an ampule supporting portion on a top surface thereof capable of supporting only one ampule at a time in a laid-down position and sloping downward toward said take-out port when said push-up member is in an upper position, whereby ampules can be lifted one by one from said housing and discharged through said take-out port; and

a stirrer in said ampule housing for stirring ampules near said push-up member.

13. The dispenser of claim 12, wherein said stirrer comprises a stirring member extending through said bottom plate of said ampule housing near said push-up member and capable of moving up and down through said bottom plate.

14. The dispenser of claim 13, said ampule housing comprises a pair of guide surfaces on side walls on opposite sides of said push-up member for guiding ampules toward said hole formed in said bottom plate of said ampule housing.

15. The dispenser of claim 14, wherein said guide surfaces are displaced relative to each other in the direction in which said bottom plate of said ampule housing slopes.

16. The dispenser of claim 12, said ampule housing comprises a pair of guide surfaces on side walls on opposite sides of said push-up member for guiding ampules toward said hole formed in said bottom plate of said ampule housing.

17. The dispenser of claim 16, wherein said guide surfaces are displaced relative to each other in the direction in which said bottom plate of said ampule housing slopes.

18. An ampule dispenser comprising:

an ampule housing for housing a plurality of ampules in a disorganized manner, said ampule housing comprising a bottom plate having an edge and a hole in said bottom plate near said edge, said bottom plate sloping downward toward said hole, and a peripheral wall having a take-out port therein located above said hole in said bottom plate;

a push-up member received in said hole of said bottom plate such that said push-up member can move up and down through said hole, said push-up member having an ampule supporting portion on a top surface thereof capable of supporting only one ampule at a time in a laid-down position and sloping downward toward said take-out port when said push-up member is in an upper position, whereby ampules can be lifted one by one from said housing and discharged through said take-out port; and

a pair of guide surfaces on side walls on opposite sides of said push-up member for guiding ampules toward said hole formed in said bottom plate of said ampule housing.

19. The dispenser of claim 18, wherein said guide surfaces are displaced relative to each other in the direction in which said bottom plate of said ampule housing slopes.
