Definitions

  • ABSTRACT A closure and finish ring assembly for a container in which both the closure proper and the finish ring which is received over the container and at the same time in turn receives the closure, may be formed as a unit and installed on the container by a press-on action without intentional rotation. After the ring and closure are in place on the container, the closure is removed by rotation thereof after releasing a lock provided to provide the container with a so-called tamper proof feature.
  • the closure is cammed axially upwardly at the same time the closure skirt is deflected slightly outwardly for release from the finish ring.
  • complete or partial threads are formed on the ring associated with the container for separating the closure from the ring as the closure is moved axially.
  • the closure and ring may be formed as a single unit by double injection molding, with the interface between the ring and closure forming, in effect, part of the mold for formation of the associated part. Molding materials and processing steps are selected so that the ring and closure do not bond to each other during formation.
  • the present invention relates to closure, systems or assemblies for jars, bottles, cans and the like, and more particularly, to closures of the so-called press-on, twist-off type wherein the closure is placed on or over an axial end of an associated container such as a jar or can without intentional rotation, and is locked in place with such container, from which it may be removed without damage only by intentional rotation of the closure.
  • Closure systems of this type have proved very successful in 'the container industry, since they possess a number of inhereint advantages. For example, in the case of baby food products or the like, which are sold commonly in small, single serving containers, the cost of the closure system must be very low in order for the entire product to be of reasonable cost. In such cases, it is desired to provide a tight seal, easy removability, and ease of manufacture and assembly.
  • a press-on, twist-off cap is very advantageous in these respects because in sealing the caps to the jars it is not necessary to index the jars to a particular position in relation to the closure, it is not necessary to provide means to tighten the cap to a predetennined torque, and yet the degree of force or torque necessary to effect removal of the cap can be carefully regulated in a simple but economical manner. Accordingly, it is known that there are a number of advantages in the presson, twist-off system.
  • closure system which has been considered desirable from the standpoint of convenience in manufacture and economy is the closure system wherein the container finish, that is, the part of the container which engages the cap or like closure upon sealing, is a separately formed or removable part of the container rather than being an integrally formed part thereof.
  • the container finish that is, the part of the container which engages the cap or like closure upon sealing
  • the container finish is a separately formed or removable part of the container rather than being an integrally formed part thereof.
  • the cap or closure itself has customarily been a relatively conventional cap, such as a metal cap having a top panel and a skirt portion and including a gasket of one sort or another on an inner surface thereof.
  • the cap has been more or less conventional with the finish ring being a separately formed element which is otherwise similar to the top and/or side finish portions of the container itself.
  • the present invention relates to closure systems having certain of the advantages of these various prior art constructions, but differing therefrom by reason of having difierent features of construction and possessing certain other and further advantages and features not found in known prior art constructions.
  • Another object is to provide a closure system in which the closure and the finish ring may be formed by a multi-step operation wherein one part of the composite assembly is formed, by injection molding for example, in one step of the operation, and the remainder of the forming operation includes the use of portions of the previously formed components as amold for the remaining parts of the assembly.
  • Another object is to provide a composite finish ring and closure which may be formed as a unit, but in which the parts thereof are readily separable for the purpose of removing the closure from a container having the ring associated therewith.
  • Another object is the provision of a composite ring and closure which may be formed separately and in which the closure is, in use, locked to the ring by means which provide an increased radial clearance between the ring and closure upon closure rotation for removal thereof, to provide reduced friction when the closure is removed.
  • Another object is the provision of a double injection molded, composite finish ring and closure assembly which may be pressed into a container as a unit without intentional rotation, and which may then be separated into two elements by removal of the closure from the ring.
  • a further object of the invention is the provision of a finish ring and closure assembly in which a tamper proof seal or lock may be provided to prevent undesired rotation of the closure or to indicate that such removal has previously been accomplished or attempted.
  • a still further object is the provision of a method of making a composite closure and finish ring assembly for press-on association with a jar or other container and the removal therefrom by rotation of the closure serving to separate the closure from the ring.
  • a still further object is to provide a ring and closure assembly for use with the associated container in which said assembly may readily be manufactured by so called double injection molding.
  • FIG. 3 is a top plan view of the container and closure of FIGS. 1 and 2;
  • FIG. 6 is an exploded vertical sectional view showing portions of the container, ring, and closure with the closure spaced axially apart from the ring;
  • FIG. 7 is an enlarged perspective view showing the tamper proof feature of one form of the closure and ring assembly of the invention.
  • FIG. 11 is a top plan view of the finish ring element of the form of invention shown in FIGS. 8 and 9;
  • the tongue and groove 56, 58 are made from a deformable material and are sized and shaped so as to be sufficiently flexible in relation to the force able to be generated by rotating the closure 24 relative to the ring 26 that the tongue 56 will ride out of the groove 58 upon such rotation and release the closure for free axial removal from the ring 26.
  • the configuration of the tongue and groove 56, 58 serves to determine, at least in part, the sealing characteristics of the closure, as well as the torque required to effect removal of the closure 24 from the ring 26. This relation is shown in FIG. 6, where the closure 24 is shown to be removed, and it will be seen in this view that the closure 24 has resumed its prior shape by reason of its own innate resiliency.
  • FIG. 7 which is on an enlarged scale, also shows that, in the preferred form of the invention, a plurality of anti-slip areas such as grooved or serrated gripping portions 76 are formed on the skirt 32 of the closure 24. This affords added convenience where the material from which the assembly is formed is naturally lubricous, for example, or is of otherwise smooth contour.
  • the finish ring 26 be formed in one stage of a two stage forming operation such as double injection molding, whereby the closure 24 is formed in another step, using the just-formed ring 26 as a part of the mold for the being-fonned closure 24, so that the resulting product is a composite assembly.
  • a bead 72 of adhesive material can be used to lock the ring 26 in place and, if of continuous extent around the groove 66, will also serve to seal the contents of the container from leakage in the region of the groove 66. Therefore, in such an embodiment, the adhesive may supplement the action of the serration 70 in locking the ring against rotation.
  • FIG. 2 clearly shows that serrations 70 may be provided in the groove 66 also for the purpose of preventing rotation of the ring, and these serrations may be present for co-operation with such an adhesive material, if desired, or may serve as a substitute therefor. Furthermore, the serrations 70 may cooperate with counterparts thereof (not shown) on the inner surface of the ring 26 in a known manner, or the gripping action provided thereby may be accomplished only by reason of the serrations 70 digging into the surface 84. Once the ring 26 is thus held in the position shown, it cannot rotate relative to the container 22 unless relatively very great torque is applied thereto.
  • the container 22 may be rescaled by the reverse process, namely, forcing the cover 24 axially over the ring 26, rotating it somewhat if necessary to bring about alignment of surfaces 38, 40 with surfaces 42, 44, respectively.
  • the container 22a includes associated therewith a composite finish ring and closure assembly 20a, with this asembly 20a in turn comprising a closure 24a and a closure-receiving finish ring 26a received in groove 66a held in place over the upper portion 300 of the container 22a by the upper rib 68a and the larger diameter, lower rib 280, both ribs 68a, 28a extending circumferentially around the upper portion 30a of the container 22a.
  • Serrations 70a or the like are shown to be provided to prevent rotation of the ring 26a in respect to the container 22a, while the ribs 68a, 28a prevent axial movement of the ring 26a in either direction.
  • threads 100 are formed in this manner so that, upon rotation of the cap 24a with respect to the ring 26a, the skirt portion 360 of the closure 24a which, in the closed position of the cap 240, snugly engages the threads 100, upon rotation of the closure 24a, gradually draws away from the threads 100 so that a clearance is formed between the threads 100 and the skirt 36a. As a result, frictional contact between these parts is gradually reduced, and radial clearance is provided to facilitate axial removal of the closure.
  • an opposite action takes place, namely, the closure 24a is located in place over the ring 25a and is progressively more firmly fastened in place upon rotation thereof in the clockwise direction.
  • locking tab 48a is the same as that of its counterpart, and in other principal respects, the form of composite closure assembly shown in FIGS. 8-14 is similar to the form thereof shown on FIGS. 1-7.
  • container 22, 22a is a glass jar or bottle. It will be understood, however, that the invention is also equally applicable to other forms of containers to be used in association with the ring and closure systems of the invention.
  • containers include plastic jars or bottles, metal cans, and the like.
  • closures and rings will be formed from plastic materials, such as thermoplastic materials which may be easily injection molded.
  • plastic materials such as thermoplastic materials which may be easily injection molded.
  • other materials including thermosetting plastics and other materials may be equally suitable for practice of the invention.
  • Ring and closure systems made according to the invention are useful with any number of products, or in fact any type of product compatible with the material comprising the ring, closure, and adhesive, if any.
  • a particular advantage of the invention resides in the fact that the threads need not be formed on the container, and therefore no orientation thereof in the packaging or filling machine or the like is necessary since the ring is of the press-on type, and the closure is a tum-off type closure.
  • the primary seal may be a plastic-toplastic seal and the thread, ramp or other configuration providing means for causing axial movement of the cap upon rotation may be varied without making changes in the plastic jar or bottle.
  • a standard jar may be made having a groove or like means for receiving a ring, and any number of different forms of rings and closures will be useful therewith, provided only that the portion thereof received by the container is standard.
  • a single style, size, and shape of jar would be equally useful with the form of the invention shown in FIGS. 1-7, the forms shown in FIGS. 8-14 and other forms not specifically illustrated.
  • the angle of inclination of the ramps 38 should not be excessive. Although the exact angle used does not form a critical part of the invention, at present, angles of the order shown in these drawings, or lesser angles, are preferred. In this connection, it will also be appreciated that the overall height of the ramps 38 should equal or exceed the axial spacing between groove 58 and the top finish portion 62 of the ring 26, so that tongue 56 will be free from engagement with the ring 26 when the closure 24 is rotated to its full extent for removal.
  • the present invention provides a novel ring and closure assembly and method for containers and the like having a number of advantages and characteristics, including those pointed out herein and others which are inherent in the invention.
  • a closure system for a container comprising, in combination, a ring for reception over an end portion of an associated container, portions of the surface of said ring forming a seal finish for receiving an axially inwardly directed closure in a sealing relation, a closure associated with said finish ring and having thereon a closure skirt with portions thereof engaged with said finish in complementary relation thereto, said ring being adaptcd to be received over a portion of an associated container without intentional rotation thereof and means associated with said closure system for providing removal of said closure from said ring upon relative rotation between said closure and said ring.
