The resilient portion of the rib may be curved inwardly along its top edge.

Abstract: A vial or other container includes a hinged closure member having a latch for securing the closure member in a closed position. The latch includes a "child resistant" configuration wherein it is very difficult for adolescents to open the container and an "easy open" configuration wherein it is relatively simple for persons with limited manual dexterity to open the closure member. The latch includes a bipositional tongue hingedly attached to either the container or closure member. The tongue is hinged to allow for the various configurations and, when in the child proof configuration, substantially requires use of both hands and a substantial amount of dexterity in order to open the closure member. Various devices are further provided to protect the tongue from manipulation by adolescents and for indicating previous tampering with the container. The closure member is connected by a hinge to the container.

Abstract: A slit valve for sealing an access opening in a vacuum chamber. The slit valve body or door is pivotally mounted adjacent the opening and has a pair of cam blocks mounted at its opposite ends. Cam follower rollers are mounted on a swing arm for reversible pivotal door opening and closing movement effected by a pneumatic cylinder. During closing movement of the swing arm, the cam followers engage the cam block and resiliently pivot the slit valve against the opening. Upon reversed, pivotal opening movement, the cam followers release from the cam block, allowing a spring to return the door to a normally opened position. The slit valve mounting is adapted to provide equal compressive sealing, both top-to-bottom and side-to-side.

Abstract: A container defined by a base and cover, with the cover being formed to fit upon the base. The base and lid are formed so that when fitted together at least one wall of each overlaps a wall of the other. The overlapping walls are formed with an aperture which become aligned when the cover and base are fitted together. The container further includes a fastening hasp attached to either the cover or the base. One end of the hasp end is formed to pass through the aligned apertures in only one direction. Once the hasp end is positioned through the aligned aperture any attempt to remove the hasp therefrom brings a portion of the hasp into contact with the wall defining the aperture. This prevents the removal of the hasp from the aligned apertures. The hasp is further formed with a tab which can be grasped and pulled causing the hasp to tear along a pre-scored line.

Abstract: A child-resistant container and closure cap combination is provided by using cooperating members on the internal cylindrical sidewalls of the cap and the cylindrical walls of the container neck. The cooperating members are a pair of studs aligned with the axis on one of the cylindrical walls projecting toward the other and three collars supported on the other of said cylindrical walls. The collars have channels through which the studs must pass in placing the cap on the container or removing it and except through those channels the collars block the studs. Two of the three collars are rotatable and the third fixed. Rotation of the cap and container will cause the stud which is positioned between the relatively rotatable collars to contact and drive a stop means on one rotatable collar. By continued rotation the stop, in turn, contacts and drives a drive post on the other rotatable collar.

Abstract: The closure assembly comprises a first cap portion hingedly connected to a second cap portion adapted to be positioned over the mouth of an associated container and including an aperture to permit dispensing from the container. The first cap portion is arranged so that in one position it overlies the aperture to close the container, and in another position is lifted clear of the aperture to open the container. The cap portions together include means so that they can be snapped together and their separation from a closed to an open position requires the exertion of a positive force by the user and the first cap portion includes at its periphery opposite its hinged connection with the second cap portion a lip which co-operates with an inwardly displaceable section of the second cap portion.

Abstract: An easy-opening container of the type commonly used to contain beverages has an end wall that includes a score line and a hinge line with the score and hinge lines together defining a partially separable panel section of the end wall.

Abstract: A fuel cap is provided with a vent system for lowering the actuation pressure of its internal pressure-relief valve in response to rotation of the fuel cap relative to the filler neck in a cap-removal direction. The vent system provides an operative connection between the cap handle and a pressure-relief valve in the cap. The vent system includes a spring for applying a closure-inducing force urging the pressure-relief valve against its valve seat to close a vent aperture in the cap, and a control system for regulating the magnitude of the closure-inducing force in response to rotation of the handle in a cap-removal direction. Use of the control system to lower the magnitude of the closure-inducing force permits the pressure-relief valve to move away from the valve seat to a venting position upon exposure to excessive fuel vapor pressure in the filler neck so that a fuel vapor-venting outlet through the cap is established during a removal of the fuel cap from the filler neck.
