<p>The body of an injection device is formed by two generally semi-cylindrical halves 6 and 7 brought together and secured by adhesive, welding or snap-fitting lugs and sockets, to make a barrel with tapers at each end. A trigger 18 is part of the moulded half 6. The halves 6 and 7 are moulded in one piece in an opened-out condition, being joined by a single long web, or several shorter webs. These extend along one pair of adjacent longitudinal edges of the halves 6 and 7 between the tapering ends, and serve as hinges when the halves are closed together to enclose a syringe capsule 1 and coil springs 12 and 13. <IMAGE></p> |
