Device for transfer of product from refill container to applicator container without exposure to atmosphere
First Claim
1. An open ended cylindrical connector to affect the transfer of material between two containers comprising:
- a) container docking ports at both ends of the cylindrical connector; and
b) a unidirectional substantially open ended hole-cutter located between and aligned co-axially with said container docking ports with the cutting-edge facing a first container docking port, said docking parts being respectively adapted to receive a neck of a donating container, at the first docking port, and a neck of a receptor container, at a second docking port, thus incorporating both containers into a single closed system;
wherein the unidirectional substantially open hole-cutter includes a plurality of half-arches, the outer surfaces of which are formed as a cutting edge, radiating out from the central axis of the cylinder with rotational symmetry to form a skeletal dome; and
a pointed membrane piercing spike mounted centrally on top of the conjunction of the half-arches.

Abstract
An open ended cylindrical connector device includes a) an internally smooth-bored first docking port at one end; b) an internally screw threaded second docking port at the other end; and c) a unidirectional hole-cutter/membrane-piercing arrangement deployed across the diameter of the cylindrical device with its cutting/piercing edges occupying the first docking port. The product is transferred from a sealed donating container to a receiving container by screwing the receiving container into the second docking port and subsequently pressing a sealed donating container into the first docking port. The seal on the donating container is punctured by the hole-cutter and releases the product for transfer through the cylindrical connector to the receiving container. The donating container docking port may be closed with a removable cap and the cylindrical connector used as a donating container screw cap.
