Apparatus and related methods for dispensation of a liquid

A dispenser, comprising:

• a container that defines a distal end located most distally with respect to said dispenser and a proximal end located most proximally with respect to said dispenser, the container contains a liquid;
• a proximal surface that encloses fixedly the proximal end of the container;
• a cover of rigid construction sealingly engaged with the distal end of the container;
• a piston slidably sealingly engagable within the container to position a piston face of the piston from the distal end of the container into contact with the proximal surface of the container;
• a cutting edge disposed about the piston face of the piston to open the cover;
• a sleeve defining a chamber configured to receive the container, the piston disposed within the chamber;
• a stalk connected to the sleeve;
• a nozzle disposed at a distal end of the stalk;
• and, a passage formed between the piston face of the piston and a nozzle outlet of the nozzle to communicate liquid from the container through the nozzle outlet by sliding of the piston within the container from the distal end into contact with the proximal surface.

A method, comprising the steps of:

• inserting a container into a sleeve having a piston disposed therein;
• advancing the piston toward the container thereby opening a covering using a cutting edge configured about a piston face of the piston, the covering hermetically sealing liquid within the container, the covering disposed about a distal end of the container;
• aligning the piston with the container following the opening of the covering;
• and
• delivering a dose of liquid as spray by advancing the piston within the container from the distal end into contact with a proximal surface enclosed fixedly at a proximal end of the container, the piston having been aligned with the container to be slidably sealingly engaged therewith.
