  • Patent number: 4391273
    Abstract: The present invention refers to improvements in disposable items, particularly self-destructing or otherwise automatically non-reusable hypodermic syringes having a self-destructing element which is actuated during the injection stroke of the piston. The invention provides an upper stop member, generally provided by a plate with a circular hole having a diameter permitting withdrawal of the plunger but not the piston and also a cylindrical protuberance adjacent the injection end of the cylinder and extending beyond the cylindrical wall so as to shield the fingers of the user from a self-destructing pin forced through the bottom wall of the cylinder under completion of the injection stroke. A cover plate for said cylindrical protuberance having an interior hole for the injection needle is also shown.

  • Patent number: 4358028
    Abstract: An improved unit-dose disposable container of molded plastic preferably manufactured by injection molding in which the flexible body, rigid nozzle and breakable tip of the container are of successively narrower widths so as to maximize the number of mold cavities, which reduces manufacturing cost. The tip is designed so that it can be rotated between the thumb and forefinger by a relative movement between same transverse to the longitudinal axis of the container so as to minimize upsetting the contents of the container when the tip is broken off.

  • Patent number: 3998224
    Abstract: This invention refers to disposable syringe containers used for injection which destroy themselves and render themselves unreusable, characterized principally in that they are made of a material which can be cut or perforated with the normal injecting movement of the piston in the syringe, thus destroying them and which have parts which engage the piston to the cylinder or to the injection needle after the first use and prevent any further use of the syringe.
