Abstract

In an embodiment, an apparatus includes a body comprising an inner body wall and an outer body wall centered about a longitudinal axis. The inner body wall and the outer body wall form a ridge at a first end of the body, and the ridge is configured to receive a force applied to the apparatus. The apparatus includes a base at a second end of the body. The base includes a flange configured to form a seal against a container wall and an aperture centered about the longitudinal axis. The base is centered about the longitudinal axis. The apparatus includes an inlet protruding from the base in a direction towards the first end of the body, and the inlet is configured to secure the apparatus to a nozzle of a cartridge. The apparatus is configured to force a material into the cartridge in response to the force applied to the apparatus.

First claim

What is claimed is:

1. A system, comprising:
a press tool comprising:
a press base;
a guide rail attached to the press base and protruding upward from the press base;
a press slidably attached to the guide rail; and
a lever coupled to the press, the lever configured to slide the press along the guide rail in response to a force applied to the lever;

a container configured to be positioned on the press base of the press tool, the container comprising an inner container wall and an outer container wall, the container configured to hold a material; and
a piston configured to be positioned within the container, the piston comprising:
a body comprising an inner body wall and an outer body wall centered about a longitudinal axis, the inner body wall and the outer body wall forming a ridge at a first end of the body, the ridge configured to receive a force from the press;
a piston base at a second end of the body, the piston base comprising a flange configured to form a seal against the inner container wall, the piston base having an aperture centered about the longitudinal axis, the base centered about the longitudinal axis; and
an inlet protruding from the piston base in a direction towards the first end of the body, the inlet configured to secure the piston to a nozzle of a cartridge.

2. The system of claim 1 , wherein the press has a diameter that is greater than a second diameter of the cartridge such that the press is configured to apply a force to the ridge of the piston without applying the force to the cartridge.

3. The system of claim 1 , wherein the flange is configured to form the seal against the inner container wall by having a shape matching at least a portion of a second shape of the inner container wall.

4. The system of claim 1 , wherein the flange is configured to form the seal against the container wall by having a radius greater than or equal to a second radius of the inner container wall.

5. The system of claim 1 , wherein the inlet comprises an inner inlet wall proximate to the longitudinal axis and an outer inlet wall distal to the longitudinal axis, at least a portion of the outer inlet wall comprising a plurality of threads.

6. The system of claim 1 , wherein the piston base has a diameter greater than a second diameter of the body.

7. The system of claim 1 , wherein the piston is made of a plastic.
