ABSTRACT:
A continuous thread closure assembly is described which achieves a required degree of full thread engagement between cap and container with a lessened amount of turning of the cap needed to achieve such engagement. The assembly comprises a container having a sloping, continuous thread finish thereon having a progressively increasing thread diameter in a direction away from the outlet of the container at a conical angle of at least about 40.degree.. A screw cap is provided having a compressible liner, if desired, on the inside of its top and a counterpart thread configuration to that of the container on the inside skirt portion thereof. The thread configuration on the cap is directly engageable with the container in such a manner that the lowest thread portion of the cap passes over the uppermost thread portion on the container without engagement thereof but is engageable with the next lower thread portion to allow for less than one turn of the cap to give greater than one full course or turn of thread engagement between the container and the cap.
