Abstract: The invention relates to a drop cap for dosing the amount of liquid in the form of drops in a container, whereby the contents thereof which are to be dosed can be put under pressure. A throttling device is arranged in the direction of flow upstream from the input opening of the output channel arranged in the body of the cap in order to ensure that a predetermined drop volume is maintained in a reliable manner particularly when large drops are present, whereby said volume should be independent from the pressure applied from the liquid. Said throttling device can be embodied as a permeable opening in an additional separating wall. The invention also relates to a container comprising a drop cap.

Abstract: A container closure having an originality ring which can be attached to a container with little force and easily removed, while making certain that the originality ring either detaches completely from the closure cap or is at least damaged visibly. The retaining elements comprise a rocker having first and second legs connected to the originality ring via an elastic web. The first leg points obliquely inward and the second leg points outward.

Abstract: An improved container closure and dosing pump or syringe has a piston formed with a truncated cone-shaped face. A spring-biased operator yieldably holds the piston sealed deeply in a dosing chamber from which it can be shifted to project essentially by the height of the truncated piston face to completely scavenge the chamber. The device is formed of only three injection molded plastic parts and a return spring, to effect inexpensive production.

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.

Abstract: A non-refillable, tamper-evident container for dispensable products, including a hollow container body having an axis and a discharge portion centered on the axis, the discharge portion having an end wall and an axially extending projection thereon, as well as a frangible link connecting the projection to the end wall. Rupture of the link creates an outlet for the contents of the container body. A protective cap is removably carried by the container body and encloses the discharge portion, end wall and solid projection thereof. The cap has a transparent, smooth and even surface constituting an inspection window to permit the condition and position of the solid projection of the container body to be viewed from the exterior of the container body and cap carried thereby.
