  • Patent number: 6513842
    Abstract: A tamper indicating seal for doors or panels such as used on airborne shipping containers. The seal includes a housing mounted over an edge of a container door and having an opening for receiving a strap of an elongated shackle having a base portion engageable with a frame or other portion of the container. A locking cage is disposed within the opening and interlocks with the strap as the strap is pulled outwardly of the opening to thereby secure the housing to the container such that any attempt to open the door will cause a visual failure of the housing.

  • Patent number: 5849142
    Abstract: An applicator for applying surface relief three-dimensional seals or medallions to containers which includes a rotatable transfer ring having a plurality of seal retaining receivers therein formed therein in which plungers are reciprocally mounted. A vaccuum header is associated with the ring so as to create reduced pressure in the receivers for removing seals from a carrier tape and retaining the seals within the receivers as the transfer ring is indexed to align the seals with containers being conveyed relative to the applicator. An activator is provided for urging the plungers from the receivers to thereby apply the seals retained therein against aligned containers.

  • Patent number: 5762386
    Abstract: A tamper resistant seal and a method of sealing an object using the tamper resistant seal are disclosed. The seal includes a receptacle and an insert adapted to be received in the receptacle. A tamper indicating wire is partially embedded in the insert and protrudes from an end of the insert. When the seal is assembled the insert is received in the receptacle and the wire extends along channels formed in opposite faces of the insert. If the wire is severed or removed from the channels by a tamperer attempting to break the seal, the structure of the channels prevents the wire from being repositioned therein to give a false indication of non-tampering. In addition, the receptacle is transparent to enable the wire to be visually examined to determine whether tampering has occurred.

  • Patent number: 5573043
    Abstract: A closure cup for interfused connection with a pressure dispenser. The pressure dispenser is of the type having an essentially rigid and pressure-resistant outer container made of a fusible and preferably thermoplastic synthetic organic polymer composition, such as a polyester or polycarbonate. The closure cup is made of a synthetic organic polymer composition capable of interfusion with the polymer composition of the outer container and is adapted for receiving and holding a valve assembly made up of a valve housing and a displaceable valve outlet. The closure cup is closed after pressurization of the complete dispenser structure. Such closure is capable of interfusion with the material of the closure cup so as to form a sealing closure by interfusion having substantially the same physical and chemical characteristics, notably resistance against aging and migration of the pressurizing medium, as the closure cup.

  • Patent number: 4946210
    Abstract: A shackle seal housing has a separate plug that is snugly received in its entirety within one end of the housing, the housing having an inwardly extending circumferential ridge and the plug having a groove in its outer wall which receives the ridge when the plug is seated. The inner end of the plug has a cavity which snugly receives the shackle end thereby preventing inward compression of the plug when it is seated within the housing. The housing may have a non-circular configuration, to prevent twisting of the shackle within the housing. The shackle strap may have a variable width border provided by an opening to permit selection of its breaking strength.

  • Patent number: 4433498
    Abstract: A key link is developed as an elastic loop (1) that can be turned upward or bent open and is carried by a slide part (3) that can be pushed on the front side into a flat housing (2) until it reaches an arrestable locking position. In the locking position, the free end (4) of the loop (1) that can be bent open is enclosed by the housing (2). For this purpose, the slider (10) that consists of the loop (1) and the slide part (3) has at least one locking latch (6) that can spring out and is intended to reach behind or engaged at least one shoulder (5) provided on the housing (2).These measures permit a simple and problem-free manufacture of said hangtag, the assembly of which only requires a pushing-together of the parts, where in the pushed-together condition an absolute secure locking of the link is achieved.
