Reconstitution device

A reconstitution device comprising:

• a receptacle having an opening surrounded by a neck;
• a cap including a first end, a second end, and an inner bore having an aperture, the first end being secured to the receptacle;
• a stopper located within the opening of the neck, the stopper including a portion capable of being perforated;
• a plunger secured to the second end of the cap and being adapted to slide along the inner bore of the cap, the plunger having a shaft;
• a locking mechanism located between the cap and the stopper for engagement with the shaft of the plunger;
• and
• an actuating mechanism located on the plunger and the cap;
• wherein when the actuating mechanism is activated, the plunger travels downwardly through the locking mechanism to perforate the stopper.

A reconstitution device comprising;

• a receptacle;
• a cap including a first end, a second end, and an inner bore having a central aperture, the first end being secured to the receptacle;
• a stopper located between the receptacle and the cap, the stopper including a portion capable of being perforated;
• a plunger secured to the second end of the cap, the plunger including a shaft for perforating the stopper;
• a locking mechanism located on the plunger comprising a thin material including a tongue capable of flexing in a vertical direction and an aperture that is coaxially aligned with the shaft of the plunger;
• and
• a feedback mechanism for indicating to a user when the plunger has perforated the stopper.

A method of assembling a reconstitution device comprising:

• providing a receptacle having a lip surrounding an opening;
• inserting a stopper into the opening of the receptacle;
• providing a cap having a first end and including flexible legs, and a second end opposite the first end;
• inserting a C-clip into an indentation at the first end of the cap;
• sliding the first end of the cap over the stopper and the lip of the receptacle, wherein the C-clip allows the flexible legs to expand as the flexible legs pass over the lip, and allows the flexible legs to contract after passing over the lip to secure the cap to the receptacle.
