Abstract: A plastic container defines a sidewall closed at one end and open at the other end. A container lip is defined at the other end which comprises a pair of spaced walls surrounding the longitudinal axis of the container, to define a recess between the walls for receiving and locking a peripheral container lid portion on the container. The outer of the pair of walls defines at least one pair of spaced points of tearing weakness to permit breaking of the outer wall and outward folding of that part of the outer wall positioned between the points of tearing weakness, to provide access to the peripheral lid portion for lid removal. The container may be designed so that the lid cannot be removed without the breaking of the points of tearing weakness, to provide tamper indication to the container and lid.

Abstract: A container for transporting and storing vessels containing hazardous liquids and a method for making such a container. The container has a cylindrical housing and a cap that screws into the mouth of the housing and is locked by a latch. When the cap is screwed into place, an elastomeric sealing ring on the cap is compressed against the housing to provide a liquid-tight seal between the housing and cap. Interlocking hook-shaped members that project from the housing and from a central location of the latch act as a fulcrum on which the latch can be pivoted. Under the bias of a serpentine tongue, a locking member that projects from an end of the latch protrudes through a bore in the housing and is adapted to be received by a hole in the cap, thus locking the cap until the other end of the lever is depressed to disengage the locking member from the hole of the cap.

Abstract: A device to indicate the application of a non-rotative force, having particular utility in recording the dispensing of a push-down activated aerosol medication dispenser. A non-rotative force on an outer cover is translated into a rotation of an indicator wheel relative to the outer cover by a set of flexible pawls engaged with a set of teeth. The pawls depress and thereby extend circumferentially when the applied force flexes them to effect a rotation of the teeth. Suitable means indicate the relative rotation of the teeth such as a window in the outer cover through which is visible indicia on the indicator wheel. The device may also include means to resist its operation by a child.
