Abstract:
1. A device for distributing substances, comprising: a delivery container holding a pertinent medium, a closing unit on said delivery container and having a hypodermic needle for delivering said medium, said hypodermic needle having an outer end projecting out of said closing unit a safety device having an annular body and being movably guided a section of said hypodermic needle projecting from said closing unit between an active protective state covering said outer end of said needle and an inactive state exposing said outer end for delivery of said medium from said hypodermic needle, said annular body being movable on said needle from said outer end of said needle in said active protective state to a position axially spaced from said outer end for delivery of said medium and vice versa, said annular body being connected to said closing unit and elastically biased toward said active protective state by elastic support elements divided by bending joints and articulated to said annular body and to said closing unit, said support elements being substantially parallel to said hypodermic needle in said active protective position and being spread out from said hypodermic needle in said inactive state, said support elements extending in one piece from said closing unit to said annular body and being divided at approximate half lengths thereof by said bending joints; a snap ring removably mounted on said closing unit and movable along said support elements to said bending joints to lock said support elements in said active protective state; and a protective cover removably coupled to said delivery container by a predetermined breakage point and enclosing said outer end of said hypodermic needle; whereby said hypodermic needle can penetrate a perforable closure of a receiving container to deliver said medium into the receiving container, and whereby said annular body is pushed back from said active protective state to said inactive state by contact with the perforable closure.
