ABSTRACT:
A venting and flow control closure device includes a disc having a peripheral sealing area attachable to a rim which encircles a dispensing opening of a liquid container and a repeating vented fracture pattern formed on the disc and extending from one edge to an opposite edge of the sealing area of the disc. The disc is made substantially of a metal foil material. The repeating fracture pattern is formed of a plurality of alternating vents and rupturable bridges. Each vent has a length substantially greater than the length of each bridge. The repeating fracture pattern has a central portion zig-zag in shape with peaks and valleys terminating in a plurality of round holes, and a pair of opposite side portions extending outwardly from the round holes of the central portion in substantially perpendicular relation to an imaginary line dividing the zig-zag pattern of the central portion into halves with all of the peaks in one half and all of the valleys in the other half. These outwardly extending portions of the repeating fracture pattern terminate in the peripheral sealing area of the disc. The alternating vents and rupturable bridges and the repeating fracture pattern formed therewith enable the disc to be attached to the rim of the dispensing opening of the container without the need for centering or indexing the design in the installation process.
