<p>SAFETY CLOSURE DEVICE A safety closure device for use in dispensing flowable material from containers. A base member is attachable to the container, and has an upstanding neck through which extends a dispensing bore. A closure cap is mounted on the neck and is rotatably and axially movable thereon. Movement is accomplished by means of a pair of tabs which are shielded by the base member except when rotated into alignment with a pair of recessed portions in the base member. Only when the tabs are rotatably aligned with the recessed portions can the closure cap be axially moved to uncover a dispensing opening, In a more complex embodiment of the invention, a second rotation of the closure cap is necessary after the axial movement is accomplished in order to uncover the dispensing opening.</p> |
