Abstract: A safety seal for a pressurized system, such as a pressurized oil sprayer used in lubricating engines, or a pressurized paint sprayer, wherein the closure, for an inlet member, for addition of material such as oil or paint, is prevented from being removed, when the system is in the pressurized state. A resilient band, inaccessible from the exterior of the system, is tightly compressed by internal pressurization against an interface between the closure and inlet member thereby locking the closure into a non-removable position. Reduction of internal pressure permits the resilient band to contract away from the interface, thereby unlocking the closure from its non-removable position, with the closure being removable thereafter for addition of material into the inlet.

Abstract: In this assembly the spout attachment has at the top of its vertical wall a flat annular wiper flange having an upstanding sealing bead. The flange is clamped between the top of the mouth of the bottle and the undersurface of the closure so that the bead seals against the closure and no liner is necessary in the closure. To keep the attachment from uncontrolled rotation as the closure is screwed on and off, the vertical wall of the attachment is provided with a pair of horizontally aligned closely spaced lugs which straddle an inward protrusion in the mouth of the bottle.

Abstract: A tamper-proof bottle for assuring a legal "chain of custody" of its contents. The bottle has adjacent its open end a circumferential series of abutment bodies, each of which co-operates with one of a series of abutment bodies carried on the inner wall of the cap's rim wall, forming a series of retainer sets. When rotated to its closed position, the cap and bottle cannot be separated without breakage; and in moving into that position, the resilient nature of the sets is sufficient to let the set bodies pass one another but after such passing to cause the deformable body portion to move so that at least a part of one will be within the axial extent of the abutment wall of the mating body portion, thus blocking against cap-removal except with breakage. The cap is also provided with one or more outlet ferrules, they being closed-ended cylinders; and a plug is provided for resealing the bottle once the closed end is cut off, the plug being self-locking once inserted.

Abstract: Improved flexible ratchet teeth are provided for allowing relative rotational movement of one peripheral surface relative to an encompassing peripheral surface. Such teeth allow relative rotational movement in one direction of rotation only during which the ratchet teeth of one peripheral surface slide over the ratchet teeth of the other. The flexible teeth which may be disposed on either or both peripheral surfaces prevent distortion of the encompassing peripheral surface obtained in the prior art when ratchet teeth of solid construction are employed.

Abstract: This relates to an improved container tamper evident bead and neck finish arrangement which provides improved tamper evident band breakage upon removal of an associated closure. Most specifically, beneath the customary retaining bead, a container neck finish is of corrugated or scalloped configuration and is of a size whereby the tamper evident band or a retaining bead thereof is stretched across the space defined by a groove between two adjacent ribs so as to provide for a degree of interlock between the stretched tamper band and the container neck finish such that the tamper evident band is restrained against rotation with the remainder of the closure when the closure is rotated to effect removal thereof. This provides for a much quicker and more reliable breaking of the webs joining the tamper evident band to the closure skirt.

Abstract: A specimen collection apparatus particularly useful for urine samples is disclosed the apparatus includes a container or beaker and a screw on self-locking top that cannot be removed without damage either to the top or the beaker.

Abstract: A thermoplastic closure comprises an annular tamper band connected to the skirt of a cap by frangible bridges. In one embodiment of the closure, axially extending ratchet teeth on the bottom of the tamper band cooperate with axially extending lugs on a container shoulder or transfer bead. As the cap is screwed onto the container, the teeth ratchet over the lugs. When an attempt is made to unscrew the cap, the ratchet teeth engage the lugs to prevent rotation of the tamper band so that continued application of an unscrewing force to the cap results in fracturing of the bridges along the intersection of reduced cross-section between the bridges and the skirt. The axial length of the engaging surfaces of the ratchet teeth and lugs is sufficient that they remain axially aligned through any initial axial separation of the cap and transfer bead until the ratchet teeth and lugs engage.

Abstract: A back-off resistant closure for resealable engagement upon a container having a neck with a ring of outwardly projecting ratchet formations includes a generally planar top portion with a depending peripheral annular skirt, the skirt having a plurality of recess formations for matingly engaging the ratchet formations on the container neck, thus preventing unwanted backing-off of the closure from the container, as well as facilitating the removal of the finished closure from conventional injection molding machinery.

Abstract: A lock arrangement for closures and containers in which the container has a radially extending flange below the threads on the neck of the container and the closure extends below the flange in the closed position of the closure and container. The flange is larger than the inside of the closure which is made of a material which is deformable and has a good memory so that the portion of the closure below the radially extending flange is deformed radially outwardly and returns to its original molded position after the closure has been applied to the container to form an undercut skirt portion affording axial closing pressure between the closure and container and resists unthreading of the closure from the container.

Abstract: This bottle has a projection or "latch" from its neck, just below the thread, and along and near the lower end of that thread. There is a gap in the cap thread, that lines up with the "latch" when the cap is fully screwed on. The cap deforms when screwed on, passing the "latch" over the end of the cap thread and into the gap. The "latch" then resists cap removal. Only torque beyond the ability of a small child (or even requiring use of a tool) frees the cap. A second projection from the neck, a "flag", is breakable. It is below the bottom end of the neck thread, just above (measured along the thread) the "latch". The "flag" can fold against the neck, but springs out if released. It catches in the cap-thread gap when the cap is unscrewed, and is torn off or broken by forcible removal of the cap. Its removal or breakage evidences that the bottle has been opened.
