Abstract: A two-piece end closure for a container includes a stationary base and a recloseable cap. The base includes a through opening for dispensing the contents of the container and an annular trough extending substantially 360.degree. around the opening. The cap includes a cover portion extending over the opening, an elongated attachment leg frictionally received in the trough, and a flexible connecting wall extending between the cover portion and the lug.

Abstract: A vented top for a bacteria culture medium tube having a body with through openings to hold one or more tubes simultaneously. A cap closes off all openings or opens them together. Vent means enable automatic venting of gases generated by the bacteria.

Abstract: This invention is concerned with a closure for a bottle or jar wherein the neck of the bottle or jar is provided with an annular bead spacer from the mouth, and the closure includes a clip removably embraceable about the neck for retention by the bead, a strap extending from the clip along the neck, and a cap on the strap remote from the clip for closing engagement over the mouth.

Abstract: A dust cover for selective use in sockets of different cross sectional configurations. The couplings are provided in hydraulic lines between a tractor and an implement where coupling and decoupling of the interconnected line is needed. The cover is used in the socket end of the coupling for cleanliness of fluid handling in the hydraulic system and to assure that the impurities are not allowed to contaminate the system by entrance into an open socket when the coupling is decoupled.

Abstract: An easy opening closure comprising an end wall, a peripheral wall joined to the end wall, and a tear strip on the peripheral wall. The tear strip extends generally circumferentially of the peripheral wall and divides the closure into a closure section and a retainer section. The tear strip is completely removable from one of the sections without removing the tear strip from the other of the sections so that the sections can be separated with the tear strip remaining attached to such other section.

Abstract: This invention relates to a closure which serves hermetically to close -- though being easily reopened -- a bottle or similar container, which possesses a neck having a dispensing orifice, a neck frontal face surrounding said orifice and an orifice bead located below the latter and having a constriction on its underside, and which closure comprises a cap serving as the head of the closure, with an upper cap wall ( or roof wall of the cap ) and a cap side wall circumferential about the latter and possessing slot means, extending from its lower rim and transversely to the latter, to permit it to splay ( or spread ) on being mounted on the mouth of the bottle, and with an inner annular bead, projecting inwards from the inner face of the cap side wall and intended, in the closing position, to engage with the underside of the orifice bead of the bottle, a sealing element, provided on the inner face of the upper cap wall and serving, in the closing position, to seal the dispensing orifice of the bottle, a lifting e

Abstract: A seal in or for a blood bag has a first tamperproof seal consisting of a tube with an end wall separated by a line of weakening from an access passage. The line of weakening is torn open to gain access to the passage. The end wall is attached also by a flexible strap, and the action of tearing the line of weakening open renders available a plug also borne by the strap. Resealing by this plug is also tamper-proof in the sense that the plug cannot be removed without evidence that removal has been done or attempted.

Abstract: Disclosure is made of a novel apparatus for the collection, separation and isolation of serum or plasma from blood obtained from mammalian capillary sources. The apparatus comprises a tubular blood collection component and an airtight closure therefor. The closure member includes a reservior and means of dispensing a thixotrope into the blood collection chamber, under centrifugal force, to effect a physical separation and isolation of the desired serum or plasma. The apparatus is advantageously employed to minimize loss of blood gases during separation and holding.

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.
