Applicator for an adhesive lavatory treatment composition

摘要

Disclosed is an applicator for an adhesive lavatory treatment composition. The applicator comprises a quantity of an adhesive lavatory composition, a piston part moveably engageable with a base part, wherein the piston part includes a piston plate and a grip element, the base part includes an upper cavity, and a lower cavity, wherein the piston plate is fitted within the upper cavity of the base part and is moveable within the upper cavity of the base part. The applicator may be a single use applicator adapted to dispense only a single dose of an adhesive lavatory treatment composition, or may be a multi-use applicator which may be refilled and reused to deliver plural doses of an adhesive lavatory treatment composition.

1. A single use applicator for an adhesive lavatory composition which comprises:
a single dose of an adhesive lavatory composition, a piston part moveably engageable within a base part,wherein:
the piston part includes a piston plate, a grip element and stop means, and, the base part includes an upper cavity containing the single dose of the adhesive lavatory composition, and a lower cavity, and, wherein the piston plate is fitted within the upper cavity of the base part and is moveable within the upper cavity of the base part only between a first position and a second position and wherein the stop means is engaged when the piston plate is in the second position thus denying further movement of the piston plate relative to the base part, wherein in the said first position, the piston part is positioned within the base part such that the single dose of adhesive lavatory composition is present only in the upper cavity; and, in the said second position, the piston part is positioned within the base part such that substantially all of the dose of the adhesive lavatory treatment composition is expelled from the upper cavity and into the lower cavity; and, wherein the cross-sectional area of the transverse of the upper cavity is less than the cross-sectional area of the transverse of the lower cavity.
