  • Patent number: 5979691
    Abstract: A two-piece, connectable article comprises a first piece and a second piece which fit together in a connected position. One of the first and second pieces has a plurality of integral, extending members having free ends that each define a latch member. The other of the first and second pieces has a facing wall that defines a plurality of apertures positioned to receive the free ends of the extending members in the connected position. The apertures are sized to cause flexing of the latch members as the latch members are placed through the apertures to assume the connected position. The extending members and facing wall are proportioned to permit the latch members to spring back to an original position in the connected position, to effectively prevent separation of the first and second pieces until at least some of the extending members are broken away.

  • Patent number: 5579932
    Abstract: A tamper-indicating, child resistant closure for a threaded bottle includes an inner cap and an outer driver telescoped over the inner cap. The inner cap includes a top wall having spaced apart upstanding ribs. The outer driver includes a top wall having a pair of top wall segments hinged for pivotal movement to, and being spaced apart from each other by a spacing rib also forming part of the top wall of the driver. Each of the top wall segments initially is secured to contiguous sections of the outer driver by frangible, tamper-indicating tabs, and the top wall segments are moved from a generally horizontal position to a generally vertical position after the tamper-indicating tabs have been broken to form a driving section in the top wall of the driver. This driving section then is directed into the space between the upstanding ribs associated with the top wall of the inner cap by moving the inner cap and outer driver axially toward each other.

  • 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: 5444183
    Abstract: A polymeric electrical enclosure has an electrical access knockout having a plurality of concentric grooves integrally molded into a wall section of reduced thickness. A plurality of angularly spaced, frangible flow leaders all bridge the outermost groove, with a lesser number bridging the remaining concentric grooves to facilitate the flow of material during molding to the knockout segments defined by the grooves. The concentric grooves are progressively deeper from the outermost to the innermost to aid in selective removal of inner segments without fracture of the outer segments. A flow leader which bridges all the grooves becomes narrower at the inner grooves, as less material need flow through that section of the flow leader, and the narrower section fractures sooner, thus aiding in selective removal of the inner segments of the knockout.

  • Patent number: 5439124
    Abstract: A closure unit for a container for storing and handling flowable products is made from at least two different thermoplastic materials, the different materials fulfilling different functions. A basic thermoplastic material (A.2) is used for sealing against the container (G.2), and an area made of another different thermoplastic material (B.2,C) is provided to fulfill additional sealing functions, to increase mechanical stability, to have a reduced permeability, and to provide increased elasticity for additional opening and closing and/or absorption characteristics. The closure unit is produced by a multimaterial injection molding process, so that contact surfaces between the different thermoplastic materials can be interconnected by reversible or irreversible positive engagement and/or by more or less pronounced melting into one another. The closure unit is in two parts and comprises a pouring part (1.2) and a closure part (2.2), or is in one part.

  • Patent number: 5386918
    Abstract: Disclosed is a closure for a container, the closure having a lid hinged to a base. The base of the closure has structure for locking the closure on a dispensing nozzle of the container. The closure has tamper evidence structure, to indicate whether the lid and base have been separated (that is, whether the closure has previously been opened). The tamper evidence structure includes a tear band; the closure cannot be opened without removal of the tear band. The closure is configured, and positioned relative to the dispensing nozzle, such that relatively little area of the closure contacts the material dispensed from the container as the material is dispensed, thereby reducing absorption of material components (e.g., flavors and/or oils of the material dispensed) by the closure. The top surface of the closure lid is configured such that the container and closure can be stably stood on end on the closure lid when the lid is in the closed position.
