CLOSURE SYSTEM
BAC,KGROUNQ OF THE IN1tENTION
(1) Field of the Invention 10001] The present invention relates generally to closure systems for containers.
BAC,KGROUNQ OF THE IN1tENTION
(1) Field of the Invention 10001] The present invention relates generally to closure systems for containers.
(2) Descri tign of the Related Art [0002] Container clbsures are devices that seal the contents of a container, thereby protecting the container contents from contamination, oxygen, moisture, spillage and evaporation. Many types of closure systems have emerged tp serve these functions. For example, two-piece closure systems have frequently been employed in canning and other food product applications. A two-piece closure system, also known as a composite closure, is typically made up of a screw band and a disk. The disk fits inside the band, between the band and the container. The disk often has a peripheral rtaised bead with an underside adapted to contact the land of the container. The disk may also have an annular ring of heat-sensitive adhesive or sealant disposed on the underside of the peripheral raised bead. This $ealdnt provides a sealing contact between the disk and the land of the container and can prevent lateral movement of the disk.
[0003] The container is typically filled with a food or beverage product before sealing the closLire system. The food or beverage product may be commercially sterile. The closure system can then be applied to the container. To close a container using a two-piece closure system, the disk is typically placed upon the container to be sealed and a screw band is loosely screwed over th~ disk onto the finish of the container. The screw band often remains loose enough so that as the container is heated and sterilized, venting of gases may take place under the dfsk. After heat-processing, the screw band is tightened and the sealed container is cooled. By virtue of the slow cooling of the container and its contents, the SUBSTITUTE SHEET (RULE 26) pressure within the container is reduced. This produces a partial vacuum within the container, causing the disk to be firmly retained against the land of the container and a hermetic seal to be formed. This type of closure is beneficial because it can maintain product seal integrity during sterilization and allows the container to be resealable by the consumer without the need for a secondary inner seal.
SUMMARY OF THE INVENTION
SUMMARY OF THE INVENTION
[0004] Briefly, the present invention is directed to a novel closure system comprising a container having a finish and a land located at the top of the finish. The outer wall of the finish, just below the land, is vertical and the land slopes downwardly, toward the outside of the container, at an angle of between about 1 and 10 .
[0005] Also present is a band adapted to be received onto the finish of the container. The band has a top portion and an annular lip extending inwardly from the top portion. Additionally present is a disk adapted to be received between the band and the container land. The disk has a raised peripheral bead, the underside of the raised peripheral bead presenting a downwardly facing channel which contains a gasket material. The ratio of the width of the channel to the width of the container land is in the range of about 2:1 to 1:1. When the disk is inserted into the band, the annular lip of the band extends inwardly beyond the raised peripheral bead of the disk and has a hook portion that engages the top and inside edge of the raised peripheral bead.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[00011] Reference now will be made in detail to the embodiments of the invention, one or more examples of which are set forth below. Each example is provided by way of explanation of the invention, not a limitation of the invention. In fact, it will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the scope or spirit of the invention. For instance, features illustrated or described as part of one embodiment, can be used on another embodiment to yield a still further embodiment.
[00012] Thus, it is intended that the present invention covers such modifications and variations as come within the scope of the appended claims and their equivalents. Other objects, features and aspects of the present invention are disclosed in or are obvious from the following detailed description. It is to be understood by one of ordinary skill in the art that the present discussion is a description of exemplary embodiments only, and is not intended as limiting the broader aspects of the present invention.
[00013] As used herein, the term "finish" means the top portion of a container which surrounds the opening of the container and is configured to accommodate a closure. For example, a finish is shown as 22 in the Figures.
[00014] As used herein, the term "land" means the lip portion of the finish which makes contact with the gasket material of the disk and forms a seal. For example, a land is shown as 21 in the Figures.
[00015] The term "skirt" refers to the vertical wall of the band, extending downwardly from the top portion of the band. For example, a skirt is shown as 14 in the Figures.
[00016] The terms "raised peripheral bead" refer to a raised ring around the circumference of the disk. For example, a raised peripheral bead is shown as 32 in the Figures.
[00017] The term "gasket material" means any type of sealing material that can be placed between the disk and container land in order to prevent the escape of substances such as gas or fluid. For example, a gasket material is shown as 34 in the Figures.
[00018] As shown generally in the figures, the present invention is directed to a novel closure system 10 comprising a container 20 and a closure engageable with that container 20. The closure of the invention can comprise a two-piece composite closure. Generally speaking, a disk 30 fits inside a band 11, between the band 11 and the container 20. The band 11 has a top portion 12, an annular lip 13 extending inwardly from the top portion 12, and a skirt 14 extending downwardly from the top portion 12. The disk 30 has a center portion 31 and a raised peripheral bead 32 circumnavigating the center portion 31. The underside of the bead 32 can present a downwardly facing channel 33 which can contain a gasket material 34. Under pressure, the gasket material 34 is designed to seal the disk 30 to the container land 21.
[00019] The band 11 can be screwed onto the container via annular threads 16 and 23, located on the outer surface of the container finish 22 and the inner surface of the band skirt 14, respectively. The annular threads 16 and 23 are adapted to receive one another and provide a tight fit between the band 11 and the container 20, thereby sealing the gasket material 34 of the disk 30 against the land 21 of the container 20. In some embodiments of the invention the annular threads 16 and 23 are continuous annular threads. A continuous annular thread may be comprised of an uninterrupted protruding helix. In certain other embodiments the annular threads 16 and 23 are interrupted threads or lugs. A lug thread may be designed so the thread segments are disposed equidistantly around the container finish. The closure has matching portions that engage each of the thread segments.
[00020] In an embodiment of the invention, at least one annular bead 40 is present on the upper surface of the top portion 12 of the band 11. In some embodiments, two or three annular beads 40 may be located on the upper surface of the top portion 12 of the band 11. The annular bead(s) 40 can be rounded, squared, or any other shape. The annular beads provide the band 11 with additional structure and stability during the tightening of the band onto the container. When the band of a typical two-piece closure is screwed onto a container, uneven force may cause the band to flex. The annular beads 40 located on the upper surface of the top portion 12 of the band 11 provide the band with stability and reduce unwanted flexing of the band.
[00021] In certain embodiments, the container land 21 slopes downwardly, toward the outside of the container, at an angle A of between about 1 and 10 (shown in Figure 3). In certain embodiments, the container land 21 slopes downwardly, toward the outside of the container, at an angle A of between about 3 and 7 . In still other embodiments, the container land 21 slopes downwardly, toward the outside of the container, at an angle A of about 5 so that the inside edge of the container land is about 5 higher than the outside edge of the container land.
[00022] The underside 19 of the top portion 12 of the band 11 and the channel 33 can also slope downwardly, toward the outside of the closure system, at angles B and C, respectively, which can correspond generally to the angle A of the container land. In an embodiment of the invention, the container land 21, disk channel 33 and top portion 12 each slope downwardly, toward the outside of the container, at an angle of about 5 .
[00023] In some commercially available containers, the land area has a downwardly sloping angle of about 15 . In contrast, a nearly flat land area, between about 1 and 10 , allows thorough coverage of the gasket material 34 over the container land 21 as the disk 30 is tightened onto the container 20. Additionally, if the angle of the disk and band corresponds with the angle of the container land, the seal area is further maximized.
[00024] In order to create the particular angle on the container land, the container 20 can be extrusion molded and removed from the rotation wheel, with excess plastic remaining on the finish as a moil. This material can then be removed using a rotating knife blade. The knife blade can be set at any angle, for example at 5 below flat surface. The knife blade then separates the container from the moil at a 5 angle. This creates an angle where the inside edge of the container land is slightly higher than the outside edge of the container land. The nearly flat land area places a more even distribution of the gasket material 34 onto the container land 21. The disk and band can be manufactured to provide corresponding angles.
[00025] In certain embodiments of the invention, the band 11 has a top-centered opening 18. In this embodiment, the annular lip 13 defines a peripheral edge 17 of a top opening 18. The disk 30 of the closure system is inserted between the band 11 and the container land 21. It can be 5 received into the band 11 just below the inwardly extending annular lip 13 of the band 11. The disk 30 can be rotatably movable within the band 11.
Similarly, the band 11 can be rotatable while the disk 30 can be frictionally held in place by the gasket material 34 and container land 21. When the band 11 is tightened onto the container 20, the disk 30 provides a seal for 10 the container 20 (shown in Figure 4).
Similarly, the band 11 can be rotatable while the disk 30 can be frictionally held in place by the gasket material 34 and container land 21. When the band 11 is tightened onto the container 20, the disk 30 provides a seal for 10 the container 20 (shown in Figure 4).
[00026] The gasket material-containing channel 33 is designed to form a seal with the land 21 of the container 20. In an embodiment, the gasket material 34 can be plastisol. Plastisol is a liquid mixture of resins and plasticizers that is solidified with the application of heat. In an embodiment of the present invention, a plastisol-lined disk forms an airtight seal against the container land to prevent the ingress of oxygen or other contaminants.
[00027] In some embodiments of the invention, when the disk 30 is inserted into the band 11, the annular lip 13 of the band 11 extends inwardly beyond the raised bead 32 of the disk 30 and has a hook portion 15 that engages the top and inside edge of the bead 32. In typical closure systems, as the band is tightened onto the container land, the down force caused by the application torque pulls to the outside of the disk insert. In the present invention, however, as the band 11 is tightened onto the container land 21, the hook portion 15 of the lip 13 applies force downwardly on the top and inner edge of the bead 32, thereby creating an equal downward force on the top, outer and inner surface of the land 21 of the container. The container land can then create a channel in the gasket material, forcing the gasket material to be distributed evenly across the inside, top and outside of the container land. This provides a better seal for the gasket material on the container land and prevents the ingress or egress of gaseous or liquid substances.
[00028] In certain other embodiments of the invention, the ratio of the width of the channel 33 to the width of the container land 21 is in the range of about 2:1 to 1:1. In particular embodiments the ratio of the width of the channel 33 to the width of the container land 21 is in the range of about 1.75:1 to 1:1. In further embodiments the ratio of the width of the channel 33 to the width of the container land 21 is in the range of about 1.5:1 to 1:1. In yet another embodiment the ratio of the width of the channel 33 to the width of the container land 21 is about 1.48:1. In these embodiments, the width of the channel 33 is slightly larger than the width of the land 21 of the container with which it engages. A relatively narrow channel 33 is beneficial because as the disk 30 is pushed downwardly onto the container land 21, the coverage area of the gasket material 34 in the channel 33 is thoroughly distributed on the top, inside, and outside of the container land 21.
[00029] In a particular embodiment of the invention, the outer wall 24 of the container finish 22, above annular threads 16 and just below the land 21, is vertical. Oftentimes, the outer wall of the container finish on containers will angle slightly inwardly. This does not provide as a large a contact area for the gasket material seal. Molding the outer wall 24 of the finish 22 as a completely straight vertical wall increases the area of the container land 21 in contact with and covered by the gasket material 34 in the disk 30. This maximizes the seal contact area and creates a center clamping force by the closure band 11 of equal amount over the top, inside edge and outside edge of the container land 21.
[00030] In processing and sterilization, the container 20 of the present invention can be filled with a food or beverage product before sealing the closure system 10. The closure system 10 can then be applied to the container 20. The disk 30 can be placed upon the container 20 and the band 11 screwed tightly onto the container 20. The container 20 can then be heated and sterilized. The closure system 10 of the invention beneficially maintains product seal integrity during sterilization and allows the container 20 to be resealable by the consumer without the need for a secondary inner seal.
[00031] The various components of the closure system of the present invention can be produced from a variety of materials, including metals, plastics or glass. In some embodiment of the invention each of the container, disk and band may each be made of the same material, such as plastic. In certain other embodiments, the container, disk and band may all be made of different materials, such as a glass container, metal disk and plastic band. In a particular embodiment, the container and band may be plastic and the disk may be metal.
[00032] In one embodiment of the present invention the band is plastic.
In this embodiment, the band can be prepared from any plastic material, including one or more selected from the group consisting of polyethylene, polypropylene, polystyrene, cycloolefin copolymer, polyethylene terephthalate, polyethylene naphthalate, ethylene-(vinyl alcohol) copolymer, poly-4-methylpentene-1, poly(methyl methacrylate), acrylonitrile, polyvinyl chloride, polyvinylidene chloride, styrene-acrylonitrile, acrylonitrile-butadiene-styrene, polyamide, polyacetal, polycarbonate, polybutylene terephthalate, ionomer, polysulfone, polytetra-fluoroethylene, polyester, vinyl ester, polyurethane and polyurea. In a particular embodiment, the band is prepared from polypropylene.

[00034] In an embodiment of the invention, the disk is metal. In a particular embodiment, the disk is made from stainless steel. Optionally, the disk can be semi-rigid. In this embodiment, the disk can have a central portion sufficiently flexible to be drawn partially inward into the open mouth of the container when the pressure within the container is less than the pressure outside the container. The deflection of the central portion of the disk provides a visual indication of the existence of a hermetic seal.
[00035] In certain embodiments, the container of the present invention can be extrusion blow molded and can comprise any suitable plastic material known in the art. The container can be of any size and should be adapted to receive the corresponding two-piece closure system. In an embodiment, the container may comprise a jar. In some embodiments, the container may comprise a bottle, such as an infant or baby bottle. The bottle may be filled with cow's milk, human breast milk or infant formula.
Once the closure of the present invention is applied to the bottle, the system may be sterilized or otherwise processed.

[00036] If the bottle is used for cow's milk, human breast milk or infant formula, the bottle may be filled and the disk of the system replaced with a nipple. The band can then be tightened onto the nipple and container, securing the nipple in place. The container and closure system can then be used to feed an infant.
[00037] The closure system of the present invention is suitable for multiple filling processes, including hot fill, cold fill, dry seal, pasteurization and retort. The closure can be produced in a variety of sizes for a wide range of food and beverage applications, such as pickled products, sauces, jams, jellies, nuts, juices, milk-based beverages, and infant formulas.
[00038] In certain embodiments, the disk and band may be made of different colors improving the esthetics of the product package.
Additionally, the disk and/or band may be produced in a manner so that they can be labeled for commercial purposes.
