Abstract

An apparatus for transferring a viscous material comprising: a) a first container capable of containing a viscous material; b) a transfer piston insertable in the first container so that the piston forms a circumferential seal with respect to the container, the transfer piston including a hole; and c) a mechanism for attaching an aperture of a second container to the hole in the transfer piston wherein insertion of the transfer piston into the first container causes the viscous material to pass through the aperture into the second container.

Claims

1. An apparatus for transferring a viscous material, the apparatus comprising:

a) a first container capable of containing a viscous material;

b) a transfer piston insertable into the first container so that the piston forms a circumferential seal with respect to the container, the transfer piston including an aperture; and

c) a second container connected to the aperture in the transfer piston;

wherein insertion of the transfer piston into the first container causes the viscous material to pass through the aperture and into the second container;

the apparatus further comprising a mechanism between the first container and the transfer piston for applying a force to the insertion of the transfer piston into the first container.

2. Apparatus according to claim 1, adapted to provide sufficient force to cause a viscous material characterized by a viscosity of at least 500 Pascal/second to flow through the aperture of the transfer piston.

3. Apparatus according to claim 2, configured so that manual manipulation of the first container and the transfer piston produces the sufficient force.

4. Apparatus according to claim 1, wherein the transfer piston is adapted to remove at least a portion of the viscous material from a mixing element as the mixing element is removed from the first container.
