Definitions

  • the present invention is directed to plastic closures for beverage, food, juice, pharmaceutical and like applications, and more particularly to a closure, a package and a method of manufacture that are particularly well suited for high-temperature (e.g., pasteurization, hot fill, asceptic fill and retort) applications.
  • high-temperature e.g., pasteurization, hot fill, asceptic fill and retort
  • U.S. Patent 4,984,703 discloses a plastic closure that comprises a shell having a base wall with a peripheral skirt and an internal thread for securing the closure to a container finish, and a sealing liner compression molded in situ on the interior of the shell base wall.
  • U.S. Patent 5,451,360 discloses a method and apparatus for compression molding the liner in situ within the closure shell. It has also been proposed to provide plastic resin barrier materials within the sealing liner for resisting transmission of gases (e.g., carbon dioxide and oxygen), water vapor and/or flavorants through the liner.
  • gases e.g., carbon dioxide and oxygen
  • U.S. Patent 6,371,318 discloses a plastic closure and method of manufacture in which the liner is compression molded in situ on the interior surface of the closure base wall, and includes a multiplicity of alternating layers of matrix polymer such as EVA and barrier polymer such as EVOH.
  • U.S. Patent 6,399,170 discloses a plastic closure and method of manufacture in which the liner is compression molded in situ on the interior surface of the closure base wall, and includes a dispersion of barrier polymer platelets, such as EVOH, dispersed within matrix polymer such as EVA.
  • high-temperature applications include, for example, applications in which the container is filled with product while the product is hot, such as so-called hot fill and asceptic fill applications.
  • high-temperature applications also include applications in which the filled package is subjected to pasteurization or retort after filling. During retort applications, for example, the filled package may be subjected to a temperature of 130°C (265 °F) for fifteen minutes.
  • High-temperature situations can also occur when a package is filled with a carbonated beverage and subjected to storage under high-temperature conditions, in which the internal pressure within the container can increase dramatically.
  • the container closure is subjected to elevated internal pressure, which tends to distort or dome the closure base wall and lift the sealing liner away from sealing engagement with the container finish.
  • the closure includes a shell having a base wall and a skirt with one or more internal threads for securing the closure to a container finish.
  • a plastic disk is loosely captured within the closure shell.
  • An annular ring extends axially from the disk adjacent to but spaced from the periphery of the disk.
  • a resilient liner is molded onto the disk over at least the central portion of the disk and over the ring on the disk.
  • the disk urges the liner into sealing engagement with the radially inner edge and the axial end of the container finish when the closure is secured to the container finish.
  • the disk includes an annular rib around the periphery of the disk, with the liner extending around the inner periphery of the rib. The disk thus urges the liner into sealing engagement with the inner and outer edges of the container finish as well as the axial end of the container finish.
  • closure, package and method of manufacture disclosed in the noted copending application address and overcome problems theretofore existant in the art, further improvements remain desirable.
  • the liner is disposed on a separate disk retained within the closure shell
  • a plastic closure in accordance with claim 1 which corresponds to a first aspect of the present invention includes a plastic closure shell having a base wall with a central opening and a skirt with at least one internal thread or bead for securing the closure to a container finish.
  • a plastic disk is retained within the shell parallel to but spaced from the base wall.
  • the disk includes a plurality of axially extending spacer elements around the disk to engage an underside of said base wall and space the disk from the base wall of the shell, and may comprise angularly spaced fingers that extend from the disk through the central opening of the base wall to retain the disk within the shell.
  • a resilient liner is disposed on an underside of the disk for sealing engagement with the container finish.
  • a, plastic disk is provided.
  • the disk includes an axially extending bead composed of a plurality of angularly spaced bead segments around a peripheral portion of the disk to space the disk from the base wall of the shell.
  • a plurality of angularly spaced fingers extend from the disk through the central opening of the base wall concentrically with the bead and retain the disk within the shell.
  • a closure and container package in accordance with a further aspect of the present invention includes a glass or plastic container having a finish with at least one external thread.
  • a plastic closure includes a closure shell having a base wall with a central opening and a skirt with at least one internal thread engaged with the external thread on the container finish.
  • a disk is disposed within the shell. The disk includes a plurality of angularly spaced axially extending spacer elements around the disk in abutting engagement with the base wall and spacing the disk from the base wall. Angularly spaced fingers extend through the opening in the base wall to retain the disk within the shell when the closure is removed from the container finish.
  • a resilient liner is disposed on an underside of the disk in sealing engagement with the container finish around the periphery of the disk.
  • a method of making a closure and container package in accordance with claim 14, which relates to yet another aspect of the present invention includes providing a glass or plastic container having a finish with at least one external thread, and a closure that includes a shell with a skirt having at least one internal thread.
  • the closure shell has a base wall with a central opening, and a plastic disk is retained within the shell parallel to but separate from the base wall.
  • the disk includes a plurality of angularly axially extending spacer elements, preferably in the form of an axially extending bead composed of a plurality of spaced bead segments around a peripheral portion of the disk, to space the disk from the base wall of the shell.
  • a plurality of angularly spaced fingers extending from the disk through the central opening of the base wall and retain the disk within the shell.
  • a resilient liner is disposed on an underside of the disk.
  • the container is filled with a fluid product, and the closure is secured to the container with the liner in sealing engagement with the container finish. Fluid is then directed into the central opening of the base wall between the fingers, between the base wall and the disk, through the gaps between the spacer elements on the disk, and then between the closure skirt and the container finish to flush any debris or liquid product that may have entered this area during handling of the closure or filling of the container.
  • FIGS. 1-2 illustrate a closure and container package 20 in accordance with one presently preferred but exemplary embodiment of the invention as comprising a container 22 having a cylindrical finish 24.
  • a closure 26 is externally secured to container finish 24.
  • Closure 26 is an assembly that includes a closure shell 28, a liner disk 30 and a sealing liner 32.
  • Closure shell 28 includes a base wall 34 and a peripheral skirt 36 having one or more internal threads 38 for engagement with one or more external threads 40 on container finish 24.
  • Closure skirt 36 and container finish 24 alternatively may include one or more beads for securement of the closure to the container, although engaging threads are currently preferred.
  • closure shell 28 may comprise a dual-wall shell that has an inner wall or skirt with internal threads 38 and an outer wall or skirt to coordinate with the sidewall of the container.
  • Closure shell 28 also may include a tamper-indicating band connected by frangible bridges or a frangible web to the lower edge of the skirt.
  • a tamper-indicating band connected by frangible bridges or a frangible web to the lower edge of the skirt.
  • Closure base wall 34 has a central through-opening 42 (FIGS. 1-3) that is coaxial with skirt 36. Opening 42 is surrounded by an axially outwardly or upwardly facing ledge 44 that is recessed from the upper surface of base wall 34.
  • Disk 30 is disposed within closure shell 28.
  • Disk 30 includes a generally flat disk body 46 having a circular periphery with an axially upwardly extending peripheral bead, which is formed in this embodiment by a plurality of angularly spaced circumferentially aligned bead segments 48, 49, as best seen in FIG. 4.
  • Bead segments 48, 49 are disposed axially to engage the undersurface of closure base wall 34 to space disk body 46 from the base wall.
  • a plurality of angularly spaced flexible resilient spring fingers 50 extend upwardly from the upper surface of disk body 46. As best seen in FIG.
  • each finger 50 is radially aligned with an associated bead segment 49, which in turn is spaced from the opposed ends of adjacent bead segments 48 by a pair of gaps 51.
  • Bead segments 49 preferably are of shorter circumferential dimension than are fingers 50, so that each finger 50 is also radially aligned with an associated pair of gaps 51.
  • Each spring finger 50 extends upwardly from the upper surface of disk body 46, and then radially outwardly in the form of a rounded bead 52.
  • beads 52 of fingers 50 are received by snap fit over shoulder 44 on shell base wall 34 to retain the disk in assembly with the shell. This retention of the disk preferably is a loose retention (before assembly to a container), allowing disk 30 to rotate with respect to the surrounding shell.
  • the ends of the fingers and the beads preferably are flush with or beneath the upper surface of base wall 34 when the closure is secured to the container finish, as best seen in FIGS. 1 and 2.
  • Sealing liner 32 preferably is flexible and resilient, and is disposed on the underside or undersurface of disk body 46.
  • Liner 32 preferably is compression molded in situ onto disk 30 while disk 30 is captured within the closure shell. That is, disk 30 is first placed within the closure shell and captured by snap fit of fingers 50 over base wall shoulder 44, and liner 32 is then compression molded in situ onto the disk.
  • the liner may be compression molded onto the disk employing an assembly fixture 60 such as that illustrated in FIG. 11, and the disk/liner subassembly then assembled to the closure shell.
  • the liner may be formed separately, such as by stamping from a sheet of liner material, and then secured to the undersurface of the disk by adhesive or other suitable means.
  • Liner 32 may be of any suitable material construction.
  • liner 32 is of resin construction, and most preferably includes a barrier material to resist permeation of gases, water vapor and/or flavorants through the liner.
  • the liner most preferably is provided in accordance with the disclosure of one of the U. S. Patents 6,371,318 and 6,399,170 noted above.
  • Other suitable barrier liners or non-barrier liners alternatively may be employed.
  • Closure shell 28 and disk 30 preferably are of molded plastic construction, such as polypropylene.
  • Container 22 may be of glass or plastic construction.
  • closure 26 is secured over the finish of the container. Rotation of closure shell 28 to engage threads 38, 40 pushes disk 30 and liner 32 over the axial end of the container finish. If disk 30 is loosely retained within the shell, as is preferred, disk 30 and liner 32 do not rotate with respect to the container finish after engagement with the finish, but merely are axially pressed onto the container finish as shell 28 is threaded onto the finish. Liner 32 is pressed into sealing engagement against the axial end of the container finish, against the radially inside edge of the container finish by a bead 54 on disk body 46, and against the radially outer edge of the container finish by a ring 56 that extends around the outer periphery of disk body 46.
  • Ring 56 has a wiper bead 58 (FIGS. 6 and 7) that slidably engages the outside edge container finish to align disk 30 and liner 32 with the edge of the container finish.
  • Disposition of disk bead 48 around the periphery of the disk places the bead in approximate axial alignment with the end of the container finish, so that compression of the liner and the disk as the closure is secured to the container does not tend to bend or distort the body of the disk.
  • flushing fluid such as air or water, may be directed into opening 42 of closure base wall 34 and between disk fingers 50 into the area between the upper surface of disk body 46 and the lower surface of closure base wall 34.
  • This flushing fluid travels radially outwardly through this area between the disk and the closure base wall, through gaps 51 between disk peripheral bead segments 48, 49, and then downwardly between the inside surface of skirt 36 and the outside surface of finish 24. Disposition of fingers 50 in alignment with gaps 51 between bead segments 48, 49 (FIG. 4) ensures that the flushing fluid traverses the entire area between the disk and the closure base wall.
  • FIG. 8 illustrates a modified liner disk 30a in which, as compared with disk 30 in FIG. 4, bead segments 49 are eliminated, and gaps 51 a between opposed ends of bead segments 48 are correspondingly enlarged.
  • Liner disk 30 of FIG. 4 is preferred because bead segments 49 provide support between the disk periphery and the underside of the closure shell base wall against forces applied to the disk by tightening of the closure onto a container finish.
  • FIG. 9 illustrates another modified liner disk 30b, in which bead segments 48, 49 of FIG. 4, or bead segments 48 of FIG. 8, are replaced by a circumferential array of angularly spaced nubs or lugs 48b.
  • FIG. 10 illustrates a modified closure assembly in which liner disk 30c terminates at bead segments 48 - i.e., does not include ring 46 and wiper bead 48 of the embodiment in FIGS. 2 and 5-6.
  • Liner 32c terminates at the periphery of disk 30c, and does not extend around the radially outer edge of the container finish.
  • FIG. 12 illustrates a modification to the embodiment of FIG. 10 in which disk 30d and liner 32d are flat in the sealing area - i.e., the disk bead 54 (FIG. 2) has been deleted.
  • FIG. 13 illustrates a modification to the embodiment of FIG. 2, in which a tamper indicating band 62 is frangibly secured to the lower edge of closure skirt 36.
  • a circumferentially continuous or segmented stop flange 64 extends from band 62 to engage a stop bead 66 on container finish 24.
  • the dimensional relationships preferably are such that, when the closure is unthreaded from the container, the tamper indicating band is severed from the closure skirt before the seal is broken at the upper end of the container finish.
  • FIG. 14 illustrates a closure and container package 70 in accordance with another embodiment of the invention.
  • a molded plastic container 72 has a finish 74 that terminates in a flange 76, which is a vestige of a trimming operation after molding.
  • a closure 78 has a skirt 80 with a tamper indicating band 82 connected thereto by frangible bridges.
  • a disk 84 is secured to the base wall 86 of closure 78 as previously described, and a liner 88 is mounted on the underside of disk 84. Liner 88 engages finish flange 76 to seal the package.
  • the dimensional relationships of the closure and container, and the flexibility of flange 76 preferably are such that tamper indicating band 82 is ruptured from skirt 80 before the seal is broken at liner 88.
  • Container 22 may be of glass or plastic construction.
  • Container 72 (FIG. 14) preferably is of blow molded plastic construction.
  • Closure shells 28 and 78, disks 30, 30a, 30b, 30c, 30d, and 84 may be of any suitable plastic construction, such as polypropylene.
  • the closure and package possess superior sealing capabilities, particularly in high-temperature applications such as hot-fill, asceptic-fill, pasteurization and retort applications.
  • the closure and package are also adapted to be flushed with fluid after filling and application of the closure to remove debris and any excess liquid that may have resulted from the filling operation.
  • Disk 30 preferably is loosely retained within the closure so that the disk and sealing liner will remain stationary with respect to the container finish while the closure shell is turned onto and off of the finish. This helps prevent damage to the liner.
  • disk 30 could be non-movably secured to the closure shell in accordance with the broadest aspects of the invention as long as a path is provided for flushing fluid between the disk and the shell. The invention is intended to embrace these and all other modifications and variations as fall within the scope of the appended claims.
