Abstract
An improved packaging and assembly is provided for a multiple-point sacrifying device for vaccinating or skin testing. In order to insure economic wage of immunological or allergenic liquid pre-assembled on the scarifying device, each cluster of multiple points is assembled with a removable surrounding envelope that achieves a hermetic seal with its mounting and which presents a transverse annual attachment wall to which an envelope-closing lid is hermetically secured after a limited quantity of liquid is deposited into the limited volume chamber surrounded by the envelope.
