  • Patent number: 4207988
    Abstract: Improvements in inner and outer closures for containers are disclosed. The outer closure is characterized by a cap member having a top wall, a side wall and a base adapted for sealing to the neck of a container. Two score lines extend across the top wall with finger gripping means attached at the apex where the two score lines meet. One score line extends down the side wall to connect with a third score line near the base which extends completely around the cap. The other score line extends down the side wall to an intermediate position and diverges away and terminates a short distance from the one score line. By pulling on the finger gripping means, the entire cap member above the third score line is removed in one piece. The inner closure comprises a plastic member sealed at its periphery to the mouth of the neck and includes a vertically aligned spike-entry port and an additive port which is oriented at an angle away from the entry port.

  • Patent number: 4204604
    Abstract: An improvement in a closure system for containers in which a cap member sealed at its base to an annular flange about the neck of the container is removeable by a cutting ring. The cap includes an upwardly projecting brim at the base separated from the side wall of the cap to provide an annular groove. The groove has at least one tapered recess. The cutting ring which can be positioned around the side wall of the cap has at least one depending tab with an inwardly directed sharpened projection. Normally, the tab rests in the recess of the groove. Upon rotation of the cutting ring, the tab is forced inwardly causing the sharpened projection to sever the side wall of the closure.

  • Patent number: 3952902
    Abstract: Method and apparatus is disclosed relating to the use of a plasma receiving assembly including a container and closure cap adapted to permit aseptic handling, storage and shipment of blood plasma. One aspect of the method is to form the plasma receiving assembly by placing a plasma receiving container within an overwrap having a gas permeable bacterial filter such that the container and overwrap may be gas sterilized followed by mechanical sealing of the container while still in the overwrap. The method further provides for use of the overwrap to lessen the chances of contamination during handling and transfer of the blood plasma including the steps of forming the container in a rigid standardized cylindrical form and limiting the volume of plasma placed in each container so that the plasma may be frozen and removed automatically.
