An easy open container end closure utilizes a pair of angled force directing score lines to direct an upward closure opening force which is applied to a pull ring or pull tab to an initial break line of finite length. The force directing score lines allow the container lid to pucker and to direct the applied opening force to the initial break line. Once this line has severed, continued lid separation acts in shear at two points of separation. The result is a container end closure which requires substantially less opening force than do prior art devices.

A two part closure for a container is comprised of a flexible foil sealing disk together with a flanged linerless screw threaded closure cap. The cap's sealing flanges contact the flexible foil sealing disk on opposite edges of the container's mouth rim and, as the cap is screwed down, these flanges bring the flexible foil sealing disk into continuous, intimate sealing contact with the container rim. Additionally, the inner closure flange draws the portion of the flexible foil sealing disk situated within the container mouth tight to eliminate creases and wrinkles in the foil sealing disk. Once the closure has been opened and the foil sealing disk removed, the container can be resealed by using the flanged linerless closure cap.

A tamper evident closure has frangible bridges detachably connecting a tamper indicating band to the skirt of a cap, and hook-like locking tabs for securing the tamper indicating band to a transfer bead on a container, circumferentially displaced from one another and all aligned with a radially extending annular gap between the tamper indicating band and the cap, such that the closure can be integrally molded from thermoplastic material in a straight draw mold without slides, inserts or post molding operations. The frangible bridges extend along, as well as across, the annular gap and are flexible so that the tamper indicating band can be extended axially relative to the cap to accommodate for variations in dimensions and tolerances in containers to which the closure is applied.

A tamper proof closure cap for a container, a tool for manufacturing the cap and a method for removing the cap from the tool are defined. The cap is designed with the tamper proof skirt as a unitary structure with the main body of the cap. The skirt has unique structural aspects which allow for less complexity in the tool and ease of removal of the cap from the tool. The tool includes a stripper ring which laterally support the skirt and permits a shift of the pivot plane for the skirt relative to the main body portion during removal of the cap from the mold.

A tamper evident closure is integrally molded in a straight draw mold with a tear out tab extending laterally outward adjacent a slot in the free edge of the closure skirt and connected to the skirt by flexible, frangible bridges. After the closure is removed from the straight draw mold, the tear out tab is rotated about the flexible, frangible bridges into the slot and is retained therein by bevelled engagement ribs along the side edges of the tear out tab which snap over and engage the side edges of the slot. A radially inwardly directed projection on the tear out tab engages the conventional transfer bead on a container, and remains engaged thereby as the closure is unthreaded, thus, producing an axial force which fractures the bridges. The tear out tab then slides free of engagement with the edges of the slot and separates leaving a visual indication of prior removal of or tampering with the closure. If an attempt is made to reinsert the tear out tab in the slot, the torn ends of the fractured bridges extend laterally outward to provide an indication of the tampering.

A resealable container enclosure includes a fitment with an annular body which snap fits over the mouth of a container, a resilient frusto-conical wall integrally molded with the annular body in a convex configuration to extend outward from the container, and a spout extending outward from frusto-conical wall. The enclosure includes a cap which, as it is screwed onto the container, engages the spout and deforms the resilient frusto-conical wall into the concave configuration producing bending moments which cause the spout to pop-up as the resilient frusto-conical spout returns to the convex configuration upon removal of the cap. A plurality of circumferentially spaced ribs extending axially and radially along the inner surface of the resilient frusto-conical stiffen the frusto-conical wall in the preferred embodiment of the invention.

A two part closure for a container is comprised of a flexible foil sealing disk together with a flanged linerless screw threaded closure cap. During the process of applying the closure to a container, the flexible foil sealing disk is formed, heated, and is tack adhered to the rim of the container. A closure cap having downwardly extending spaced sealing flanges is then screwed onto the container. The cap's sealing flanges contact the flexible foil sealing disk on opposite edges of the container's mouth rim and, as the cap is screwed down, these flanges bring the flexible foil sealing disk into continuous, intimate sealing contact with the container rim. Additionally, the inner closure flange draws the portion of the flexible foil sealing disk situated within the container mouth tight to eliminate creases and wrinkles in the foil sealing disk. Once the closure cap has been applied and tightened down, the two part closure is subjected to a second heating step to fully activate the heat sensitive adhesive carried on the under surface of the flexible foil sealing disk thus securely adhering the flexible foil sealing disk to the container. Once the closure has been opened and the foil sealing disk removed, the container can be released by using the flanged linerless closure cap.

A closure for a resealable container comprising an annular container engaging member fixedly attached to the edge of the container and a lid having an end wall and an annular skirt, the lid being attached to and separable from the container engaging member at a failure zone. In one embodiment the lid is adapted to reseal the container after it is separated from the container engaging member by turning the lid upside down and positioning it such that the annular skirt engages the container engaging member and the end wall covers at least a portion of the opening of the container. In another embodiment, the lid is also adapted to reseal the container after it is separated from the container engaging member by positioning the lid such that the annular skirt engages the container engaging member and the end wall covers at least a portion of the opening of the container. The invention also includes a stackable container having the closure described above.
