Abstract: A syringe (18) has a longitudinal body (28) with an interior (228) in which a pharmaceutical substance is arranged, a needle connected to one longitudinal end of the body (228) and a rigid needle shield (38) encasing the needle. The rigid needle shield (38) is essentially water vapour tight. The syringe (18) according to the invention allows for preventing needle clogging and, thus, proper provision of pharmaceuticals, particularly by subcutaneous, intramuscular or ocular injection.

Abstract: A double-sealant tube structure for a caulking gun includes a container (10), a first feeder (20), a second feeder (30), and a pushing member (40). The container has an interior provided with a separation plate (12). The pushing member is provided with two first thrust portions (42) corresponding to the first feeder and a second thrust portion (41) corresponding to the second feeder. The pushing member is further provided with two cutting blades (43) each intersecting the separation plate of the container. Thus, when the pushing member pushes the first feeder and the second feeder, the separation plate is cut by the cutting blades to allow the pushing member to move forward.

Abstract: The syringe contains an outer barrel, a compressible inner barrel threading through a support ring inside the outer barrel, and a plunger sealing the back of the outer barrel. The outer barrel has a hollow cylindrical body with an outer orifice at a front end. Inside the outer orifice, a positioning ring is provided whose circumference is configured with parallel ribs so that a number of channels are formed. The inner barrel has a bellows structure capable of being compressed and stretched along the axial direction. A tubular inner orifice is configured at a front end of the bellows structure. The plunger has a cylindrical shape. On a front side of the plunger, there is an axial chamber in the center surrounded by a push surface. Along the circumference of the plunger, there is at least a circling rib. The syringe could be applied to an ordinary adhesive gun.
