Each of the tangs and the body have an interior axially extending triangular stiffening rib. An insert with a head and a bifurcated shank is attached to the flange opposite the body and may be sheared from the flange for insertion into the body core. The shank forms a locking opening which captures a web in the body core for securing the insert locked to the body. The insert prevents the tangs from compressing inwardly to open the seal. The flange has a living hinge so it can be folded over to permit reading ID data from the flange in stacked bins.

  • Patent number: 6398273
    Abstract: The invention relates to a tag (1) comprising a shackle (4) mounted directly adjoining a sliding part (3), whereby said shackle in its locked position forms a closed circle together with the face of the wall of the tag housing (2). A locking element (5) positioned inside the housing in its locked position preferably clicks into both the sliding part (3) and the end of the shackle (4), thereby locking same in said position. In the locked position, the locking element (5) is pushed against a retaining cam (11) arranged inside the housing. If during an attempt to open the tag the sliding part (3) or shackle (4) is pulled and a certain pull force is exceeded, the built-in breakage area (12; 15) in the housing tears, thus providing clear, unambiguously and irreversible evidence of the attempted manipulation. This type of tag is especially suited as safety lock or safety seal.

  • Patent number: 6293599
    Abstract: A non-reusable locking device for sealing containers. The locking device employs an insertion bolt which is insertable into a receptacle having locking flanges to prevent removal of the insertion bolt once inserted into the receptacle. A rigid housing surrounds and protects the receptacle, preventing access to the insertion bolt once inserted into the receptacle. A multi-part locking collar secures one end of a flexible cable permanently and rotatably within the housing. The second end of the cable is crimp-secured into a bore at one end of the insertion bolt. The flexible cable permits attachment to any type of container. The device forms a contiguous loop which can not be severed without destruction of the device. Once the loop is severed, it cannot be rejoined and provides instant indication that the container has been tampered with.

    Abstract: A steel bolt has weakening grooves at one end to which a head is swaged, the head having two frusto-conical portions at opposite ends. One end has a frusto-conical step for receiving a pair of jaws of a bolt breaking tool. A resilient spacer is attached to the bolt next to the head for limiting the depth of entry of the bolt head into a hasp hole, to provide access clearance for the tool and to permit the bolt to tilt to assist in breaking the bolt. The spacer is received in one hasp hole smaller in diameter than a second hasp hole to limit the depth of insertion of the spacer and the bolt head tapered end portion into the hasp. A seal with a conventional locking mechanism has a frusto-conical end region which partially engages the other hasp hole. The bolt and seal cooperate to lock the seal axially at different positions so the seal is engaged with one hasp hole and the bolt head engaged with the other hasp hole.

The inserting part, which can be inserted into the socket from either of two insertion directions of the aperture, has at least one tongue, which has a suitable elasticity and can expand in radial directions relative to the axis of the inserting part under its condition free of any force application. The aperture of the socket has a face to engage and stop the socket, which is vertically provided relative to the axis of the aperture. In inserting the inserting part into the socket, the tongue undergoes contraction to facilitate its passage through the aperture, and when it has been completely passed through the aperture, the tongue restores its original condition and radially expands to abut against the engaging face of the aperture, preventing the inserting portion from being pulled out of the socket.

  • Patent number: 3994521
    Abstract: A locking means for providing a seal comprising a locking shell formed with a central passageway which is internally tapered with an opening that changes from conical to triangular in shape and which carries spring loaded ball bearings and a retainer such that a cable can be inserted through the central opening in a first direction, thus, depressing the spring and allowing the balls to relieve pressure on the cable in said first direction but which provides substantial and locking pressure on the cable when the cable is placed under tension in the opposite direction. The cable may also be attached to a second fixed member such that a seal may be made by placing the locking case and the fixed member on the same cable.

  • Patent number: 3980337
    Abstract: A locking seal for use on doors of freight cars, trailer trucks and other large doors to prevent casual pilferage by non-professional thieves. In a first embodiment a length of steel cable is provided with means on each end for locking engagement with each other. In a second embodiment of the invention, a length of steel cable is provided with a stop on one end and the other end is provided with an assembly comprising a locking cap and means secured to the cable for receiving the locking cap in non-removable engagement. The locking means of either embodiment is adapted for rapid assembly without the use of special tools, yet the design of the two locking portions thereof gives the assembly a strength of engagement which is greater than the strength of the steel cable connecting the portions. The male portion of the locking means, when assembled, is completely enclosed within the female portion to protect the attachment of the cable to the male portion from physical damage.

  • Patent number: 3954295
    Abstract: Tamperproof shackle seals formed as one-piece plastics mouldings and including, inter alia, the following features: a plug portion of non-circular outline for co-operation with a mating countersunk portion of the socket mouth to prevent effective insertion of a blade; a stop formed on the strap near the plug to limit the effective length of the strap when used with a padlock hasp; respective webs extending along the lengths of resilient fingers in the socket and connecting them either to the adjacent socket wall, or to those fingers disposed adjacently thereto on either side; to prevent free movement of the resilient fingers; and a filler for the plastics material which presents a barrier to heat re-sealing after tampering.

  • Patent number: 3937507
    Abstract: A disposable padlock which cannot be opened by a key but whose locking effect can only be nullified by the use of sufficient force to deform the padlock. A shackle is automatically engaged when inserted into a body portion of the padlock. Engagement members mounted in the body portion are biassed to engage recesses in limbs of the shackle in such a way that the padlock will deform before the shackle will be removed by the application of force. Means may be provided for preventing rotation of the limbs of a sheared shackle engaged by the body portion.
