Abstract

Systems for material deposition. One such system includes a number of containers arranged relative to one another in a conical or other shape, pointing toward a common deposition point. When not actively depositing material, the containers are held at a distance from the deposition point. Another system has a rod disposed within a container and a flexible tip on the rod seals a material exit of the container when biased closed. Pressurized gas introduced into the container forces the rod away from the material exit and material from the container. In yet another system, a container includes a barrel adapter having a one-way air valve that seals the container and creates a vacuum, preventing material from leaking from the container. Upon application of a pressurized gas, the one-way valve is forced open and material is deposited from the container. The valve closes automatically in the absence of the gas.

First claim

What is claimed is:

1. A system, comprising a plurality of containers for dispensing one or more materials, said plurality of containers each having a respective material dispensing end and a respective dispensing mechanism, and being arranged with respect to one another about a common point of deposition with their respective material dispensing ends oriented towards said common point of deposition, each of said plurality of containers included within a respective mount and being translatable between an original position at which a respective container does not dispense material and a deposition position at which the respective container dispenses material when actuated by its respective dispensing mechanism.

2. The system of claim 1 , wherein each of the plurality of containers is mounted on a common stage translatable along an axis.

3. The system of claim 1 , wherein the plurality of containers are arranged in a cone shape, with their respective material dispensing ends each oriented towards the common point of deposition.

4. The system of claim 1 , wherein the plurality of containers comprise syringes.

5. The system of claim 4 , wherein the syringes are arranged in a cone shape, with their respective material dispensing ends each oriented towards the common point of deposition.

6. The system of claim 5 , wherein each of the plurality of containers is received in a respective one of a plurality of holders, said holders being of different sizes.
