Abstract: A container closure system includes a plurality of equally circumferentially distributed pins extending outwardly from the tubular neck of the container near the opening. A detachable cap consists of nested inner and outer cap members. The inner cap member is dimensioned to receive the container neck and includes a plurality of sidewall openings for receiving the pins. The outer cap member has a plurality of locking wedges disposed on its inner surface. The inner and outer cap members are assembled so as to permit mutual rotation. Thus, when the cap is emplaced over the open end of the container, the pins are received in the openings to thereby inhibit mutual rotation between the inner cap member and the container. Then, a twist of the outer cap member in a clockwise direction brings the ramp portion of each locking wedge into engagement with one of the pins, thereby drawing the cap and the tubular member together to effect a secure closure.

Abstract: A method and apparatus are disclosed for detachably joining two members at a plurality of points along their corresponding edges and without longitudinal displacement of these edges during and after closure of the joint. A movable wedge means is advanced between pairs of force receiving points connected to each of the two members. As the wedge means is advanced in the apex direction, the pairs of points are forced apart and, in direct response, the corresponding edges are drawn together. Variations on two fundamental embodiments are disclosed, one is linear and the other is circular. In the linear embodiments, two doors, panels or bars are joined. In the circular embodiments, round tubes or rods are joined or a circular cap is secured to a container or enclosure. The invention may also be embodied in kits for joining linear or circular members. In other embodiments, a gasket material and/or other component is retained between the corresponding edges.

Abstract: A second cylindrical element with a side wall oriented generally parallel to the first plane is telescopically interconnected with a first cylindrical element and includes an upper surface. The second cylindrical element is rotationally displaceable between, first, second and third angular positions within a second plane orthogonal to the first plane and is telescopically displaceable between compressed and expanded positions. A biasing device biases the first and second cylindrical elements into the expanded position. A locking device maintains the first and second cylindrical elements in the first angular position when the first and second cylindrical elements are placed in the expanded position. The locking device enables the biasing device to displace the first and second cylindrical elements into the second angular position when the first and second cylindrical elements are displaced from the expanded position into the compressed position.

Abstract: A tamper resistant container includes a container having a hollow body and a removable cap. In a normal position, the mouth of the container body is threadably secured to a mated threaded section of the cap and the entire assembly is maintained in an upright position by an underlying load support surface. In an inverted position, the container body is detached from the container cap and inverted such that the opposite end of the container body is placed within an unobstructed interior cavity formed in the cap. In this configuration, the cap supports the container body with the open mouth of the container body exposed to permit access to the interior of the container.

Abstract: A tamper indicator includes a first indicator element coupled to a first cylindrical element, a second indicator element positioned within a second cylindrical element and displaceable between a first position spaced apart from the first indicator element and a second position contacting the first indicator element. The first indicator element changes visual states when it contacts the second indicator element. A biasing device biases the first indicator element toward the second indicator element. A locking system maintains the first and second indicator elements in a locked, spaced apart configuration while the first and second cylindrical elements remain in a first location. The locking device enables relative movement to occur between the first and second indicator elements after the first and second cylindrical elements have been displaced from the first position into a second position.
