Abstract
A closure for dispensing one or more active agents into a container comprises a sealed or sealable chamber having a breakable wall and a hollow piston slidably mounted in a piston guide. Said hollow piston comprises an outer wall having an end in the chamber and at least one ventilation aperture. Said end has a cutting formation. Said hollow piston is slidable in the piston guide between a ventilation position in which the at least one ventilation aperture allows ventilation of the chamber and a sealed position in which the at least one ventilation aperture is sealed to prevent ventilation of the chamber and a deployed position in which the cutting formation has broken through at least a portion of the breakable wall. The outer wall has a retaining formation which engages with the piston guide to releasably resist sliding of the hollow piston between the ventilation position and the sealed position and the deployed position. The hollow piston may have an outer wall, and said outer wall has an end within the chamber, facing the breakable wall, wherein the cutting end has a first edge having a cutting formation and a gap in said cutting formation.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
