Filed:

Dec 23, 1991

Appl. No.:

7/813115

Inventors:

International Classification:

A61M 500

US Classification:

604110

Abstract:

A hypodermic syringe is provided having a barrel with a movable plunger therein to inject a fluid through a hollow needle thereof which is housed within a passageway of a needle assembly that is attached to the barrel by ultrasonic welding means or other permanent attaching means. Positioned between sacrificial supports in the needle assembly and the barrel is a deformable base. The deformable base houses an enlarged head of the needle which is in contact with energy storage means within the passageway of the needle assembly. The plunger has a rupturable boot thereon which, upon completion of an injection, contacts a deformable base forcing it downward and severing a sacrificial support means within the needle assembly thereby permitting the base to move the enlarged head of the needle downward, until it is blocked by the passageway. Further movement of the base forces the enlarged needle head from the base and into contact with the rupturable boot. Movement of the base continues until the rupturable boot is ruptured by the enlarged head of the needle and the enlarged head of the needle is released from the base thereby triggering a projection of the needle into a hollow portion of the plunger by transfer of energy from energy storage means.

Abstract:

A machine for forming a carton from a carton blank using a forming cavity uses at least one gripper for gripping and transporting the carton blank toward the forming cavity along a path of travel (such as from the hopper to a transporter in a linear fashion). A plurality of grippers may be provided for gripping and transporting the carton blank toward the forming cavity along the path of travel. The or each gripper may be adapted for gripping a lateral side of the carton blank, and the gripper(s) may be connected to a transporter adapted for moving in a reciprocal fashion along a linear path of travel. The machine may also include a forming cavity adapted for being raised and lowered, as well as a low level hopper for holding the carton blanks such that each is raised to associate with the gripper(s). Related methods are also disclosed.
