ABSTRACT:
An ampul comprising a container having a reduced neck which supports an integral closure part that is removable by tearing away frangible portions. The neck can be sealingly applied over the seating cone of a hypodermic syringe whereby the syringe and ampul are firmly joined as one unit. The ampul is preferably produced as a single piece of a thermoplastic synthetic such as polypropylene whereby the ampul neck has sufficient elastic ductility to be elastically expanded by applying it to the seating cone of the syringe, thereby to assure a firm coherence. To permit air to enter to container when suctioning off the ampul contents, the ampul neck has on its inside an axial ventilating means.
