  • Patent number: 6367639
    Abstract: A safety container incorporates a slidable locking pin with an integral but separately lockable locking tab. The locking pin is internally biased by an integral S-spring which, in cooperation with the lid on the container, urges the pin to slide in a slideway in the lid of the container. The locking pin may be locked into a closed position, however, by rotation of the locking tab into a flexed position. In this position, the locking tab cannot slide within a mating slot in the hinge lid and thus the locking pin cannot slide in the slideway in the lid. Alternatively, the locking tab may be rotated into a non-flexed position in which the locking tab can be urged to penetrate the mating slot in the lid and allow the locking pin to slide in the slideway in the lid. By use of the locking pin, the safety container can be set to require the user to engage in at least distinct hand motions in order to open the container.

  • Patent number: 5325980
    Abstract: An improved vial assembly is provided for storing a quantity of material for cryogenic freezing, such as a sample of semen for use in artificial insemination. The vial assembly includes a locking mechanism to prevent the vial from being opened and then reclosed prior to final use. The locking mechanism includes a pair of apertured locking members, one on the vial, and one on the cap of the vial. The locking members are positioned for mutual alignment only when the cap is securely tightened onto the vial. A locking pin is provided for one-way insertion through the apertures of the locking members to prevent the cap from being removed without severing or destroying the locking pin. With this locking mechanism, the integrity of the contents of the vial is substantially ensured until the vial is selected for use and the locking pin is severed in the presence of a patient recipient. A secondary vial is also provided which mounts to the main vial.

  • Patent number: 4609121
    Abstract: A child resistant container construction. The dispensing opening of the container is normally closed by a plug having a pull tab thereon. The plug is removable and reinsertable in the dispensing opening. The plug is formed so that it is distortable. A rigid, rotary locking member is carried by the plug. In one angular position on the plug, the locking member prevents distortion of the plug and thereby prevents plug removal. In a second angular position on the plug, the locking member permits distortion of the plug upon pulling the pull tab, thereby permitting its removal from the dispensing opening. In other embodiments, the locking member can be completely removed from the plug to permit plug distortion and removal.

  • Patent number: 4150760
    Abstract: The enclosure comprises a base having perimetric side walls and a cap having coaxial perimetric side walls. The cap and the base have a major axis and a minor axis. A longitudinally extending locking bar is rotatably mounted in the center of the cap and has a length slightly greater than the minor axis of the base. The cap and base have coextensive slots formed in opposing walls which slots start at points on opposite ends of the minor axis and extend in the same direction peripherally about the cap and base for approximately 45.degree.. The portions of the slots on the opposite ends of the minor axis have a thickness which is approximately twice the thickness of the locking bar. The remainder of the slot has a thickness which is approximately equal to the thickness of the locking bar. In this manner, when the locking bar is rotated into the slot, it will proceed through the single thickness area and be biased into the double thickness area where it will be held against further rotation.
