  • Patent number: 4953728
    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.

  • Patent number: 4825801
    Abstract: An improved tamper indicating seal is disclosed, characterized by the generation of a unique signature pattern which, if altered, is indicative of tampering. The seal includes a layer of transparent material which is applied to at least a portion of a secure object or container. A plurality of particles of refective material are randomly arranged within the layer in a unique orientation. When the seal is exposed to light, the particles reflect a portion of the light to produce a unique reflective pattern which corresponds with the orientation of the particles. Alteration of the particle orientation as a result of tampering alters the reflective pattern. Thus when the reflected pattern of a seal does not correspond with its original signature pattern, tampering is indicated.

  • Patent number: 4813564
    Abstract: The package includes a body and a closure. A readily breakable electrical oscillatory network sans power supply is physically connected between the body and the closure. The network is tuned to resonate at a predetermined frequency. The package is monitored by a transmitter-receiver when it is distributed to a customer. The transmitter produces pulse signals in a carrier frequency band which overlaps the resonant frequency of the network. During monitoring the package is placed in the field of the transmitter and the oscillatory network is excited to produce a decaying pulse for each transmitter pulse. The receiver is gated during the interval when each transmitter pulse is generated but is receptive of the corresponding decaying pulse from the network. If the package is sealed, the oscillatory network is intact and the receiver receives decaying pulses which produce visual or audible signals. If the package has been opened, the network is broken and no signals are produced.

A supplemental opening with removable closure is provided at a lowermost point in the container, for also extracting contents under gravity feed. The supplemental opening is preferably located at the end of a slope, causing material in the container to accumulate over the supplemental opening. Particular removable closures include plugs, tethered plugs and frangible panels.

  • Patent number: 4754889
    Abstract: A cap adapted to cooperate with a container to seal and unseal the container. The cap comprises a circle-shaped knife carried by an inner surface of the cap and a lid adhesively secured to a portion of the inner surface of the cap. The container is sealed by positioning the cap over an opening of the container, which opening is defined by a container edge, and then securing the lid of the cap to the container edge by induction or conduction. The container is unsealed by exerting pressure on the cap whereby the knife cuts through the lid thereby cutting a circular portion out of the lid and unsealing the container. The circular portion cut out the lid remains adhesively secured to the cap.

  • Patent number: 4747500
    Abstract: A tamper indicating closure for use with a container having a neck with an opening in which at least a portion of the closure is transparent. A destructible seal is bonded to the container neck providing a hermetic seal which is visible through the closure to indicate package integrity or tampering. In some embodiments, a transparent insert member is provided through which the seal element is visible, and after removal of the seal element, the insert member serves to reseal the closure to the container neck. In some embodiments, access is obtained to the container by unthreading and removing the closure from the container neck and puncturing the destructible seal element. In other embodiments, the seal element is bonded to the flat closure top or the insert so that the seal element is fractured upon initial opening movement of the closure to remove it from the container neck.

  • Patent number: 4723672
    Abstract: A tamper-proof container for medicaments or the like includes a receptacle and a cap, each featuring self-locking means so that when mutually engaged the container can only be accessed by changing its profile. Two external components, a guard and a shield, respectively, must be broken at their line of integration, and disengaged to provide access to a slot for parting the container at its neck. Such parting, provides access to a barrier which must be cut along a pre-scored line. The arrangement is such that the cap can be threadedly engaged with the receptacle to store a medicament dosage cup and includes a sanitation cover.

  • Patent number: 4722449
    Abstract: A container closure attachable directly or indirectly to a container neck sealed by means of a pierceable film seal. The provision of a film seal covering the container neck guarantees the user that the contents of the container are authentic and original as supplied by the manufacturer. The film seal is pierced as the closure is adjusted from an intact to an access position on the container neck. In the upper intact position, a safety band remains intact. The closure can be adjusted to the lower access position only after the safety band has been removed, and the film seal is pierced as the closure is adjusted to the lower access position. Ratchet-like serrations may be provided on the inner side of the safety band engaging the container, thus making it impossible to unscrew a screw-type closure without removing the safety band. The safety band may be provided on a separate intermediate piece which may be snap-fitted or screwed onto the container neck.

  • Patent number: 4666063
    Abstract: An integral seal member is formed across the outlet in the neck of a tamper evident, thermoplastic container by adding to the thermoplastic material such as polyethylene, 3% to 16%, and preferably about 8% by weight, of an anhydrous solid inorganic particulate additive such as an anhydrous siliceous material or calcium carbonate so that the material becomes brittle enough that the seal member tears cleanly from the neck within the confines of an undercut at the interface between the seal member and neck. Torque is applied to the seal member by providing in the top of a conventional screw cap which forms a resealing closure for the container once opened, a recess with serrations which, when the cap is removed and turned upside down, engage serrations on the peripheral edge of the seal.
