SAFETY CONTAINER AND CLOSURE CAP UNIT THEREFOR

摘要

A safety container and closure cap unit therefor includes means for detachably latching or attaching the safety closure cap unit to the neck portion of the container body by manually inserting the safety closure cap unit on the neck portion of the container body and imparting rotational movement to the closure cap unit in the form of a partial turn or revolution without manipulation of any parts or instrumentalities in the closure cap unit or in the closure cap housing or on the container body other than the rotational movement of the closure cap unit itself. The closure cap unit may be removed from the neck portion of the container body by the simultaneous application of manual pressure on a plurality of manually operable means located at a plurality of pressure points spaced from each other on the periphery of the closure cap housing unit and simultaneously therewith imparting rotational movement in the form of a partial turn or revolution to the closure cap unit in a direction opposite to the direction of movement imparted to the closure cap unit by the said first partial turn or revolution, and then manually withdrawing the closure cap unit from the neck portion of the container body. A fluidtight seal is effected between the closure cap unit and the neck portion of the container body as the closure cap unit is thus installed upon the neck portion of the container body.
