Abstract: A pressure-type containment device with an improved lid sealing feature is disclosed. A lid disk seats on a shoulder along the interior wall of a container mouth and is held in place by a fastening ring adapted to fit into the container mouth. A resilient gasket, such as an O-ring, is wedged between the fastening ring and the lid disk along the interior wall of the mouth. The margin of the fastening ring confronting the gasket is tapered to urge the gasket against the interior wall. A pressure increase within the container expanding the lid disk causes compression of the gasket, enhancing the seal.

The self-centering closure retainer can be readily rotated about and removed from the primary cap without disturbing the cap.

Abstract: A luggage case, especially one of the type having the body and covering lid portions of similar frames of open rectangular shape on which the covering material is applied, wherein the peripheral welting at the bottom corner of the body portion and at the top corner of the covering lid are structurally adjusted with respect to the frames so as to more effectively protect the covering material at the peripheral corners of the luggage case against wear and abrasion under use conditions.

Abstract: A port structure for passing sterile fluids or other biological material, and a method for making the same is disclosed. The port structure includes a flexible sleeve having a rigid thermoplastic tube secured therein. The outer surface of the sleeve has greater thermoplastic properties than the inner surface, enabling the sleeve to be heat sealed to the fluid passage means without sealing off the inner surface. The rigid tube has a free end extending outside the sleeve, having a thermoplastic diaphragm which seals off the free end. When a sterile connection between two fluid passage means incorporating the port structure is desired, the free ends of each rigid tube are aligned and softened, and each thermoplastic diaphragm is opened. The free ends of the rigid tubes are then brought into contact and held in position under a slight pressure while the thermoplastic tubes cool and solidify, thereby creating a permanent connection.

Abstract: A reclosable container assembly is disclosed comprising a container body having an open end and a cover for closing the open end. The cover has a wall portion extending into the open end of the container body and interengaging therewith to provide a snap-fit therebetween. The cover has a peripheral flange including a portion extending radially outwardly across the open end of the container body and terminating in a peripheral skirt. The underside of the radially extending flange portion is provided with a peripherally continuous V-shaped recess providing a line of weakness along which the material of the cover fractures and tears in response to an attempt to displace the cover flange in the direction to separate the cover from the container body. The material along the line of weakness fractures in response to a displacement force less than that required to disengage the snap-fit between the container body and cover, and provides a visual indication that the container assembly has been tampered with.

Abstract: A relay assembly has a flexible contact blade mounted on a contact carrier through the use of non-conductive support blocks which permit flexing of the blade as it moves with the carrier, thereby causing a wiping action between the movable and stationary contacts within the relay.

The zip tag includes a part for manual engagement to facilitate closing of the sealing device.

Abstract: A thermoplastic pharmaceutical solution container includes a neck portion having at least one port through the neck portion. A thermoplastic port protector or closure covers the port and defines a frangible section. The closure has a length to diameter ratio providing good mechanical advantage leverage to rupture the frangible section when the closure is pushed sideways.

Abstract: A method of sealing containers is disclosed in which a glass jar having a small upwardly convex bead on its rim is filled and sealed using a metal foil membrane with a heat seal resin on its undersurface and a plastic snap cap having a material thickness over the bead on the jar of at least twice the height of the bead. The foil membrane is induction heated while high unit pressure is applied against the top of the snap cap to impress the bead on the jar and foil membrane into the plastic of the cap to form the foil membrane over the convex surface on the bead and seal the membrane to the jar.

Abstract: A container closure with a screw cap that after the opening of the container remains attached to the same, by means of a hinge. A sealing ring is joined to the lower end of the cap and rotatably connected to the container, but impossible to remove, as the inner diameter of the ring is smaller than the outer diameter of a bulge on the container. Between the cap and the sealing ring is a breakable connection and an unbreakable part serving as the hinge. When the cap is unscrewed the sealing ring is after a while obstructed by the bulge, which causes the breakable connection to break, whereafter the unscrewed cap can be swung aside around the hinge so that the contents of the container can be freely poured out.

Abstract: The invention relates to the combination of a container and a cap for closing that container, the container having a mouth, the upper surface of which defining a practically flat plane, and being provided with an upstanding rim extending along the entire perifery, the cap having an upper panel and a sealing channel filled with sealant surrounding this panel, the inner diameter of said channel being smaller than the inner diameter of the rim and larger than the inner diameter of the upper surface of the mouth of the container, while the depth of the sealing channel is in excess of the height of the rim over said upper surface of the mouth.

Abstract: A closure with a self-closing top which may be substantially removed from contact with its associated base to provide a substantially unobstructed filling opening.

Abstract: An improved seal between a flexible plastic container and its closure cap, wherein the cap is provided with an internal annular shoulder engaging the tapered side surface of an annular lip provided by the neck of the container. The shoulder bears inwardly against the lip with a force sufficient to flex that lip inwardly and maintain the same in a condition of stress. Ideally, the cap is formed of a plastic of limited heat shrinkability at autoclaving temperatures; therefore, heat sterilization of the sealed container and its contents results in slight contraction of the cap and further increases the integrity of the seal. Where the container is formed of plastic material capable of softening slightly at autoclaving temperatures, the shoulder tends to penetrate the lip to a limited extent during such autoclaving to create an undercut in the lip.

Abstract: A composite stopper comprises a body of resilient plastics material and a head surmounting the body. The head has a skirt extending around the body and a sleeve which is force fitted into a blind recess in the body. The fit of the sleeve causes the adjacent body portion to expand into engagement with the inner surface of the skirt.

Abstract: A sheet metal container wall or end closure is provided which includes a weakening line in the sheet metal and a rib formed across the weakening line to facilitate rupture of the residual metal in the weakening line. Such container wall may also have a hollow button formed in it with the weakening line and rib formed in the button whereby flexing of the button stresses the rib and weakening line to initiate rupture of the residual metal in the weakening line.
