Abstract
A syringe includes a barrel having a nozzle and an open end, and a plunger movably located within the barrel for dispensing a flowable material through the nozzle. A cover with a guide opening for the plunger can enclose the open end of the barrel. The plunger includes at least one and preferably a pair of tabs at a distal end of the plunger opposite the nozzle, with each tab having a catch on a side of the tab. A handle is attached to a distal end of the plunger, and has a cavity with a pair of shoulders positioned for engagement by the catches for retaining the handle on the plunger. A cap is inserted into an outer opening to the cavity, and includes a pair of projections for engaging a side of the tabs opposite the catches to prevent the catches from being removed from the shoulders.
Claims18
A syringe, comprising:
- a barrel having a nozzle and an open end;
- a plunger movably located within the barrel for dispensing a flowable material through the nozzle, the plunger having at least one flexible plunger latching device at a distal end of the plunger opposite from the nozzle, the at least one flexible plunger latching device having a catch projecting from a side of the at least one flexible plunger latching device;
- and
- a handle attached to the distal end of the plunger, the handle having at least one handle latching device, the catch of the at least one flexible plunger latching device engaging the at least one handle latching device for retaining the handle to the plunger, the handle further including a cap, the cap including a projection located adjacent the at least one flexible plunger latching device on another side of the at least one flexible plunger latching device opposite from the catch for preventing the catch from disengaging from the at least one handle latching device.
A syringe, comprising:
- a barrel having a nozzle and an open end;
- a plunger movably located within the barrel for dispensing a flowable material through the nozzle, the plunger having a latching device at a distal end of the plunger opposite from the nozzle;
- and
- a handle attached to the distal end of the plunger, the handle also having a latching device, in engagement with the latching device of the plunger for retaining the handle to the plunger against separation, one of the latching devices of the plunger and of the handle being flexible, and the handle further including a cap, the cap including a projection located adjacent the one flexible latching device, on a side of the one flexible latching device opposite from the other of the latching devices.
A syringe, comprising:
- a barrel having a nozzle and an open end;
- a plunger movably located within the barrel for dispensing a flowable material through the nozzle, the plunger having a shaft with one or more elongated openings along a length of the shaft, at least one elongated opening of the one or more elongated openings sized to closely receive the nozzle of the barrel and having an enlarged central circular or keyhole aperture;
- and
- a handle attached to a distal end of the plunger.
A method for storing the plunger on the barrel of a syringe, the syringe including a barrel having a nozzle and an open end;
- a plunger movably located within the barrel for dispensing a flowable material through the nozzle, the plunger having a shaft with one of more openings along the length of the shaft, at least one opening of the one or more openings sized to closely receive the nozzle of the barrel;
- and a handle attached to a distal end of the plunger, the method comprising the steps of:
- i. removing the plunger from the barrel;
- ii. supporting the barrel in an upright, vertical manner;
- and
- iii. inserting the nozzle of the barrel into the at least one opening to rest the plunger horizontally on the barrel.
