Abstract
An injector pack has a box which houses in separate positions a firing mechanism and a syringe housing. The firing mechanism has safe and cocked conditions and as it is located in the box it is constrained to adopt the safe condition by a sleeve grip being held against rotation while a protruding barrel co-operates with cams to rotate it. The firing mechanism when removed can be screwed by its barrel to the rear end of the syringe housing while that is held by the box, and then the whole injector can be withdrawn for use. The syringe is made operable by rotating the barrel to the cocked condition. Pressing the grip forwards then releases a plunger to act on the syringe. The previous retraction of the plunger can be done using a pillar formation upstanding within the box and over which the barrel can be sleeved.
