A unit dose storage and dispenser cartridge for a unit dose of an ingredient includes a storage and dispense container dispensably containing a unit dose of the ingredient. The container includes a cylindrical interior wall defining a cartridge passageway having an ingredient-containing ingredient storage cavity portion. The container further defines a dispense opening communicating with the ingredient storage cavity portion and includes a first scaling member removably sealing the dispense opening. A dispense piston is movable by a dasher rod through the ingredient storage cavity portion so as to dispense the unit dose of the ingredient through the dispense opening. An openable vent is positioned in registry with the cartridge passageway.

Unit dose dispense package

A composition and method for providing temporary masking of electrical and electronic components compatible with a high speed production operation. The composition is a radiation curable viscous liquid composition which provides minimal adhesion properties and substantial cohesive properties so that when cured, it can be readily removed in the manner of an adhesive tape. In particular, the radiation curable composition is characterized by cured properties a) of positive adhesion to the substrate to which the composition is applied, but insufficient adhesion to resist peeling forces applied by hand; and b) of sufficient cohesive strength to allow substantially all of the cured composition to be stripped mechanically or by hand in a single piece. Suitably the adhesion of the cured composition (22) to the substrate (16) as measured in the tensile shear mode, is between about 5 and 55 psi. This level of adhesion is sufficient to prevent ingress of solvent solder, plating or coating materials but low enough to allow easy dry stripping mechanically or by hand.
