  • Patent number: 7052055
    Abstract: A fastening-type security seal comprises a sealing body for sealably receiving the free end of an elongated fastening portion and an identification tag, all integrated, one with the other. The identification tag is formed with a weakening line extending from a first side edge to a second side edge of the tag, dividing it into a first region on one side and a second region on the other side of the line. The identification tag is positioned between the sealing body and the fastening part so that, in use, the tag effectively forms part of fastening portion. A pulling tab is situated on the identification tag adjacent one of the ends of the weakening line, which enables one to tear the tag, thus separating the first region from the second region.

  • Patent number: 6435089
    Abstract: A manual imprinter for transferring the image of a relief formation to a writing surface, preferably to imprint a document with the number of a security seal personalized by a relief numbering. The manual imprinter, in the presently preferred embodiment, comprises a support art adapted to support the numbered portion of the security seal, and an arm carrying a graphite block, hinged to the arm. The arm has a guide for a manual actuator, to which the graphite block is fixed. When the arm is closed against the arm, the block is pressed against the numbered portion of the security seal, the document to be imprinted being interposed therebetween. The operation of the actuator forces the graphite block across the region of the relief number of the seal, resulting in the transfer of the image of the number to the document.

  • Patent number: 6231579
    Abstract: A padlock type marking seal having a receiving body (2) with internal locking teeth (4) to receive the tip (9) of a loop of the seal that is integral with the body, and there being a marking tab (6) also integral with the body (1). In order to improve seal application, to ensure autopenetration into the material to be marked (e.g. meat), the tip is sharpened and there is a stop (11) on the loop, adjacent to and behind the tip so as to allow an applicator device to force the sharpened point to penetrate the material to be marked. The loop of the seal has a reduced thickness region defining a pivot point (8) with respect to the body, and the part (7) of the loop between the first end and the sharpened tip is substantially in the form of the arc of a circle. A reception cavity (3) in the body of the seal has an axis substantially tangential to the arc when the loop is pivoted about the pivot point, until its tip begins to enter said cavity.

  • Patent number: 5118148
    Abstract: Label holders used for closing and sealing bags have the disadvantage of having to be individualized (numbered) since one type of violation would be destroying the label holder to withdraw the security seal intact and then substituting it with a new label holder and re-using the seal.The label holder of this invention has two protuberances formed with rectangular openings on one portion thereof, which pass through two corresponding openings in the other portion when the label holder is closed. Two stops, one on each side of the strip of the outer surface between the two corresponding openings are provided. The security seal has a capsule and a lock interconnected by a thread, which in the sealed configuration are separated by the first protuberance, a part of the lock passing through the opening in such protuberance and a head of the lock being locked within the capsule. The part of the lock is connected to the head by weakenings.

  • Patent number: 4818002
    Abstract: A high security sealing system is described wherein a single-piece security seal has a lock introduced in a cavity through two openings formed respectively in two elements to be sealed. In order to prevent that a predeformation allows an apparent closing of the system, whereby a violation could take place, the invention proposes the formation of a deflecting member (18, 18') inside the cavity (9), so that, when the lock (26) of the seal (13) is introduced, the lock is inclined with respect to the axis of the openings (12, 21), whereby its locking arms become fastened not only laterally with respect to the inner opening (21) of the two openings, but also above or below them.

  • Patent number: 4197982
    Abstract: A device for closing and sealing bags which eliminates the tightening of the mouth, and makes the operation simple, rapid and safe. The device, according to the invention, comprises a flat housing with an open bottom which receives the folded mouth (preferably two series of folds reminiscent of an accordion) of a bag. An element is extended between the two larger sides of the housing, passing through aligned orifices in the folded mouth of the bag. This effects immobilization between the element and the two larger sides. In the preferred embodiment, the element is, in reality, two lengths of cord fixed to one of the larger sides and freely passing across the other. In this case, the larger sides form part of two halves of the housing, which are separable for opening the bag. In the closed position, the two halves can be locked and sealed.
