  • Publication number: 20170087307
    Abstract: A medicament dispensing mechanism is disclosed that is configured to eject successive doses of the medicament from a medicament chamber. An embodiment of the dispensing mechanism includes a housing and a plunger rod configured for ejecting the doses of medicament from the chamber. The dispensing mechanism further includes an actuation mechanism that comprises a trigger associated with the housing and having a ready and a fired position with respect thereto. The trigger is configured for manipulation by a user for successive movement in a generally axial dosing motion from the ready position to the fired position in which the trigger is associated with the plunger rod to cause the plunger rod to eject one of the doses of a predetermined volume and a resetting motion from the fired position to the ready position that comprises axial rotation, wherein the trigger is uncoupled from the plunger rod during the resetting motion.

  • Publication number: 20160346487
    Abstract: An exemplary embodiment of the present disclosure can provide an injector including a trigger mechanism, an energy source, and a user-operable firing-initiation member. The trigger member can include a trigger member having a retainer portion, and a ram assembly having a ram configured to pressurize a medicament container for expelling a medicament therefrom and a trigger engagement member configured to engage the retainer portion of the trigger member in a pre-firing condition. The energy source can be associated with the ram for powering the ram to expel the medicament, and the user-operable firing-initiation member can be operable for causing an axial rotation between the trigger engagement member and the retainer portion from the pre-firing condition to a firing condition in which the trigger engagement member is released from the retainer portion to allow the energy source to fire the ram.

  • Publication number: 20080223872
    Abstract: A dispenser for dispensing small items such as pieces of candy is disclosed herein. The dispenser includes an outer housing and an inner housing slidably coupled to the outer housing, the outer housing and the inner housing defining a main cavity thereinbetween. The dispenser includes a pocket within the inner housing that can be separated from the main cavity by slidable movement of the inner housing with respect to the outer housing. The outer housing includes a divider for at least substantially blocking off the pocket from the main cavity when the inner housing moves from a closed position to an open position such that small items cannot enter the pocket. When the inner housing is in the closed position, a small item can enter the pocket but cannot be accessed from outside the small item dispenser, and, when the inner housing is in the open position, the pocket can be accessed from outside the small item dispenser without small items being able to enter the pocket from the main cavity.
