Abstract
Provided herein is a drug delivery device including: a reservoir for a product, said reservoir having a distally projecting end-piece defining an axial passageway for the transfer of the product, said end-piece having a distal portion, an adaptor having a collar engageable around said end-piece, and a securing structure for locking the axial movement of said collar with respect to said end-piece. The adaptor further comprises a foldable element capable of going from a folded configuration in which said foldable element substantially surrounds said distal portion of said end-piece, to an unfolded configuration, in which said foldable element leaves said distal portion uncovered. An adaptor for forming a drug delivery device is also provided.

A drug delivery device comprising:
- a reservoir for containing a product, said reservoir having a distally projecting end-piece having a longitudinal axis A and defining an axial passageway for the transfer of the product from the reservoir, said end-piece having a distal portion,
- an adaptor having a collar engageable around said end-piece, and
- a securing structure for locking axial movement of said collar with respect to said end-piece once said collar is engaged around said end-piece, wherein
- said adaptor further comprises a foldable element capable of transitioning from a folded configuration in which said foldable element substantially surrounds said distal portion of said end-piece, to an unfolded configuration, in which said foldable element leaves said distal portion at least partially uncovered, the foldable element provided with threaded portions forming a continuous thread when the foldable element is in the folded configuration.
An adaptor arranged for cooperating with a reservoir having a distally projecting end-piece having a longitudinal axis A and defining an axial passageway for the transfer of the product from the reservoir, for forming a drug delivery device, said adaptor comprising a collar engageable around said end-piece, and a foldable element capable of going from a folded configuration in which said foldable element substantially surrounds a distal portion of said end-piece, and an unfolded configuration, in which said foldable element leaves said distal portion at least partially uncovered, the foldable element provided with threaded portions forming a continuous thread when the foldable element is in its folded configuration.
