Abstract

A syringe dispenser may include a plunger having an outer threading, a barrel adapted to contain liquid or semisolid fluid or any other material to be dispensed and to receive the plunger, the plunger being movably attached to the barrel, and a nut having an inner threading. The nut may at least partly enclose the plunger and the barrel, such that the inner threading of the nut engages with the outer threading of the plunger. A stand, an application plate, and a method of dispensing a controlled and measurable amount of liquid or semisolid fluid from a syringe dispenser are also disclosed.

Claims

1. A syringe dispenser, comprising

a plunger having an outer threading;

a barrel adapted to contain a material to be dispensed and to receive the plunger, the plunger being movably attached to the barrel; and

a nut having an inner threading;

wherein the nut at least partly encloses the plunger and the barrel, such that the inner threading of the nut engages with the outer threading of the plunger; and

wherein the nut is a snap-on nut being releasably attached to the plunger and the barrel.

2. The syringe dispenser according to claim 1, wherein the barrel has a flange extending in a perpendicular direction to a longitudinal direction of the barrel.

3. The syringe dispenser according to claim 2, wherein the nut has a recess adapted to receive the flange of the barrel.

4. The syringe dispenser according to claim 1, wherein the outer threading extends in a longitudinal direction of the plunger.

5. The syringe dispenser according to claim 1, wherein the plunger has a plurality of side walls extending in a perpendicular direction to a longitudinal direction of the plunger.

6. The syringe dispenser according to claim 5, wherein the cross section of the plunger is cruciform.

7. The syringe dispenser according to claim 6, wherein the outer threading is arranged on an outer surface of each of the side walls of the plunger.

8. The syringe dispenser according to claim 1, wherein the inner threading extends in a longitudinal direction of the nut.

9. The syringe dispenser according to claim 1, wherein the plunger has a top having a marking corresponding to a marking of the nut.

10. The syringe dispenser according to claim 1, wherein a seal is attached to a bottom of the plunger for sealing the plunger against an inner wall surface of the barrel.

11. The syringe dispenser according to claim 1, further comprising a cap releasably attached to a tip of the syringe dispenser.

12. A stand for supporting syringe dispensers, comprising:

an upper section having a plurality of through holes, each of the through holes being adapted to receive a syringe dispenser according to claim 1; and

a lower section having a plurality of through holes, each of the through holes being adapted to receive a tip of the syringe dispenser.

13. An application plate, comprising:

a plurality of compartments, each of the compartments being adapted to receive a material receiving unit; and

means for releasably attaching a stand according to claim 12 above each compartment, such that the material receiving unit may be filled by material contained in the syringe dispensers supported by the stand.

14. A method of dispensing a controlled and measurable amount of material from a syringe dispenser, the method comprising:

providing a plunger having an outer threading;

providing a barrel containing material;

movably attaching the plunger to the barrel;

releasably arranging a snap-on nut having an inner threading around the plunger and the barrel;

engaging the inner threading of the nut with the outer threading of the plunger; and

rotating the plunger relative to the nut and the barrel a distance, such that a controlled and measurable amount of material corresponding to the distance is dispensed from the syringe dispenser.

15. A syringe dispenser, comprising

a plunger having an outer threading;

a barrel receiving the plunger, such that the plunger is movable relative to the barrel; and

a nut having an inner threading;

wherein the nut at least partly encloses the plunger and the barrel, such that the inner threading of the nut engages with the outer threading of the plunger; and

wherein the nut is releasably attached to the plunger and the barrel.
