  • Patent number: 5474194
    Abstract: This relates to a color change system to be incorporated in a flexing area of an end panel of a closure. The color change system includes a dark background coating on a flexing portion of the closure end panel to which there is bonded by way of an adhesive such as a varnish, ink or coating a brittle layer which due to the flipping action of the flexing portion of the end panel will fracture. The brittle layer is preferably of a light color and is colored utilizing a fluorescent dye. The combination of the background color and the fluorescent color of the brittle layer produces a first color in the original closure and when the end panel flexes and the brittle layer fractures to not only crack but also tear apart or delaminate from itself, to reflect its own light color much more brilliantly, the color of the color change system drastically changes to indicate tampering. This color change is irreversible. The color change system may also include a message indicia.

  • Patent number: 5467880
    Abstract: A safety screw cap indicates prior opening of a container to protect consumers from prior contamination. The screw cap has an annular band encircling its lower end which is separated from the screw cap by a perforated line. The band is affixed to a fixing clement and the fixing element attached to the container when the screw cap is screwed in place. An unattached leader portion of the band can be lifted easily to peel the band from the container. As the band is peeled from the container, it is simultaneously tom from the screw cap at the perforations. Once the band is removed, the screw cap can be unscrewed and the container unsealed. Before peeling the band away, the screw cap cannot be unscrewed without causing obvious damage to the screw cap or band. In addition, the torque required to shear-separate the band from the fixing element, the fixing element from the container or the screw cap from the band is greater than that which can be applied easily by a normal adult.

  • Patent number: 5148931
    Abstract: This invention provides a new and simple tamper-resistant, safety closure for a container having threaded neck. It requires the user to align the two arrows, then give it an upward lift while turning in the counter-clockwise direction to unscrew it from the container.Features of the invention useful in accomplishing the above objects include an outer cap and an inner cap. The interior surface of the outer cap has a plurality of identical protrusions, called the type A protrusions, and one type B protrusion. The exterior surface of the inner cap has a plurality of identical grooves, called the type A grooves, and one type B groove. If the type B protrusion is lifted into the type B groove, then the two caps inter-lock and turning the outer cap in the counter-clockwise direction would also turn the inner cap in the same direction, resulting in the unscrewing of the closure from the container.

  • Patent number: 5133470
    Abstract: A tamper-proof plastic vial is rendered tamper-proof during transport to and from a specimen-receiving site. The vial comprises a container and cap molded together in one piece. The cap is inserted onto the container during the manufacturing phase and is secured thereto by a first destructible connector in the form of an arrow-like projection so that the integrity of the container is ensured until a specimen is received. Thereafter, a second destructible member in the form of a flexible one-way strip is attached to form a second destructible connection. The container carries an outer channel which receives a peripheral edge of the cap to establish a tortuous bacterial path and to resist accidental opening of the cap. The first destructible connection is created in response to a controlled shrinkage of the assembly during the cooling phase of manufacturing.

  • Patent number: 5123555
    Abstract: A plastic cap is used on containers, particularly of the type used commercially for five-gallon bottles containing liquids such as drinking water. A bead is formed on the exterior, preferably above the elevation of the horizontal tear line conventionally used in such caps. The bead is preferably flat on the outside surface and wide in a vertical sense. The bead functions to cause the cap to engage the neck of the container more securely. It also functions to retain in place a dust cap which fits over the top of the cap. It further functions as a seal for the type of cap used in certain water dispensers. Such dispensers are used without removing the cap from the container in that the top disk is opened after the container has been installed in the dispenser. The bead seals against the inside of a sleeve incorporated in such a dispenser.

  • Patent number: 5085333
    Abstract: A tamper evident overcap has a tear band which is offset radially from both a ring member sonically welded to a container shoulder and a cap, by generally radially extending frangible bridges. The bridges are severed by applying force to a pull tab extending radially and axially from the tear band in alignment with a gap in the ring member so that there are no undercut faces on the overcap which can consequently be molded in a straight draw mold without cams or slides.

  • Patent number: 5074424
    Abstract: This relates to the provision of a closure having a mechanically actuated button with a tamper indicating arrangement. A transparent panel overlies the end panel of the closure and there is provided a message indicia either on the upper surface of the button or the under surface of the transparent panel with their being carried by the transparent panel a pleated screen which shields the message indicia either by overlying the same or by blending with the message indicia in color. One end of the pleated screen is fixedly attached to the transparent panel while the opposite end has a releasable bond. When the closure is applied and the mechanical button moves towards the transparent panel, the pleated screen is clamped between the two with the result that the pleated screen is flattened and elongated rupturing the releasable bond so that once the closure is removed from the container and the button moves down away from the transparent panel, the pleated screen can collapse exposing the message indicia.

  • Patent number: 5018632
    Abstract: This relates to a tamper indicating closure which includes a closure cap having a button which is movable between an elevated position and a downwardly recessed position in accordance with the state of closure of an associated container. In particular, the button is provided with a tamper indicating arrangement which will include a first layer directly attached to the button and an overlying second layer which is connected to the button generally at the periphery thereof. The first layer is in the form of a photoactive layer and the second layer is in the form of a friable filter material. Normally the second layer protects the first layer, but when the button changes its shape, the friable filter layer will crack and expose the underlying photoactive layer to cause a change in the photoactive layer. This change could be in the form of the disappearance of a message, including a UPC code or the developing of a previously formed message on the photoactive layer so as to make that message appear.

  • Patent number: 5004111
    Abstract: An improved innerseal for sealing containers includes a body portion having an upper surface and structure connected to the upper surface for grasping by a user, whereby the body portion may be removed from a container quickly and efficiently. The body portion includes structure for preventing passage of fluid therethrough, and structure adapted for bonding the body portion against the upper rim of the container with a first bonding force. The bonding structure has a first bonding portion for sealing against the container rim and a second bonding portion which is adhered to the first bonding portion with a second bonding force which is less than the first bonding force. Consequently, a first part of the first bonding portion will delaminate from the second bonding portion over the container rim and remain adhered to the rim, while a second part of the first bonding portion will remain adhered to the second bonding portion, thereby exposing the opening in the container when the grasping structure is pulled.
