Definitions

  • This invention pertains generally to devices and methods for sealing and opening bottles or similar containers and, more particularly, to extracting a stopper from a bottle by rotating a sleeve that is threaded onto the bottle.
  • a completely adequate means for quick and easy removal of corks or other stoppers from wine bottles, for example, should meet four basic requirements. The first is that the stopper should provide an adequate seal against the inside walls of the neck of the bottle. The second is that a permanently installed pulling device should not protrude through the bottom or sides of the stopper and should not split or tear the stopper because of the likelihood of resultant wine leakage and/or wine oxygenation or other contamination. The third is that installation of the stopper and stopper-puller mechanism into the wine bottle should not unduly complicate the present bottle-corking technology used throughout the industry.
  • the fourth is that the stopper should be easily extractable by the consumer without the use of a cumbersome auxiliary device.
  • the foregoing requirements are also applicable to other bottled beverages as well as to some liquid foods.
  • bottlers continually seek advanced closure designs to improve the aesthetics and usage factors for non-cork closures, such as currently served by the metal screw-cap market, or similar non-corked bottle segments of the market. [0011] Therefore, a need exists for an apparatus that allows for "easy extraction" of the stopper while still providing an adequate stopper/glass seal that meets the four basic requirements outlined above.
  • “easy extraction” means that no cumbersome, awkward, or clumsy auxiliary equipment, such as cork screws that must be screwed into the stopper by the consumer, blade style removers that require inserting a pair of blades between the stopper and bottle, or air-pump removers that require a needle to be forced through the stopper and air pumped into the bottle to increase pressure, and so on, is required of the consumer, and that adequate pulling forces are as easily applied as with conventional cork screws.
  • a further need exists for advanced closures, with or without corks, that provide adequate sealing, may be opened without resorting to the use of external equipment, and which satisfy seal integrity, taste, and aesthetic criteria for a variety of bottled fluid products.
  • the present invention satisfies these needs, as well as others, and overcomes the deficiencies of previously developed bottle closures.
  • the present invention pertains to various embodiments of sleeved closure capsules, and associated adaptations of stoppers and bottles, that can provide the desirable appearance and use factors of traditional corked bottles while simplifying opening the bottle and serving the beverage. In many cases, bottling costs can also be reduced by employing the systems, devices, and methods of the present invention.
  • the invention is particularly well suited for use with beverages such as still wines and sparkling wines (champagnes), although it may be used in connection with bottles that contain other types of liquid food products.
  • several aspects of the invention are to provide for (1 ) extracting the stopper (e.g., cork) in response to torque that is easily applied by the user without a separate tool, (2) storing a reseal cap as part of the traditional-looking package, (3) resealing the bottle without reusing the stopper, (4) providing a drip resistant pour spout, (5) masking the threads of the bottle neck to simulate a foil-finished bottle, and (6) preventing inadvertent seal loss and providing tamper indications.
  • a bottle sealed with a stopper is opened by rotating a sleeve that is annularly disposed about the neck of the bottle.
  • the seal or stopper is removed from the bottle by rotating a closure capsule that is disposed about the bottle neck.
  • the closure capsule comprises at least a threaded sleeve, and may include other elements adapted for removing the stopper and/or resealing the bottle.
  • the closure capsule forms a part of an overall closure system, also referred to as a closure, that can include a seal or stopper assembly.
  • a closure that can include a seal or stopper assembly.
  • One of the objectives for many of the embodiments of the present invention is that of simulating the appearance of traditional foil-wrapped bottles. It will be appreciated, for example, that the appearance of threads on a wine bottle have often been perceived as a sign of low quality wine due to their association with the use of metal screw caps used to seal bottles containing lower quality still and sparkling wines. Although the present invention relies on threads on a bottle for functionality, an aspect of the invention is to hide the threads and provide the appearance of a conventional foil wrapped bottle.
  • Another object of the invention is to minimize potential undesirable consumer perception associated with the present invention. Accordingly, another aspect of the invention is to provide a closure capsule that can be reinstalled on the bottle after removal. After removing the stopper from the bottle by rotating the sleeve of the closure capsule, a wine steward, waitperson, or consumer can generally spin the capsule back onto the bottle to retain the desired bottle aesthetics.
  • the closure embodiments described herein may be generally divided into four functional types; namely, natural cork-based closures for non- pressurized and pressurized fluids (including traditional corks, agglomerated corks, and technical corks made of a mixture of finely ground cork and a bonding agent), and synthetic cork-based closures for non-pressurized and pressurized fluids.
  • Non-pressurized closures are directed toward applications such as still wine and olive oil
  • pressurized closures are directed toward applications such as champagne, sparkling wine, beer, and sparkling juices.
  • Table 1 summarizes general closure types according to the present invention.
  • the described bottle closures span a number of variations and improvements suitable to a wide variety of applications, cost factors, and aesthetic criteria.
  • the sleeve portion of the capsule is generally configured as a structural element, typically fabricated from a polymeric material, that surrounds a substantial lengthwise portion of the neck of the bottle.
  • the length of the sleeve generally exceeds its diameter or the bottle diameter, and is more preferably about one and one half times (1.5X) to about four times (4X) the sleeve or bottle diameter, depending in part on the length of the stopper to be removed.
  • Plug sealing comprises the use of anchored or anchorless stoppers, formed into appropriate shapes, for retention within the neck of the bottle to plug the pouring spout and thereby stop fluid flow within the bottle neck.
  • a specially designed anchor may be installed within the compliant material of the stopper, which typically comprises either natural cork stoppers, or synthetic cork stoppers, as employed within the wine industry, whereby cork removal is performed by rotating an associated closure capsule which engages the anchor to open the bottle.
  • the closure capsule of the present invention preferably replaces the traditional metal foil capsule.
  • a beneficial aspect of the cork pulling designs is that the cork is not fastened to the closure capsule and, therefore, is not subjected to rotation in response to the rotation of the closure capsule unless friction is overcome. It will be appreciated that the total work required of the user for rotating a cork of conventional size and shape within a bottle while performing axial cork extraction would increase, relative to that required to extract the cork without rotating it.
  • the engagement between the closure capsule and anchor head (attached to the stopper) is preferably configured to be dispersed over a wide area to allow for cost effective implementation of the closure elements, such as being molded from polymeric materials (i.e. thermoplastics).
  • the closure capsules are configured to engage the exterior of an anchor head having a diameter equal to or preferably greater than approximately one-half the inside bottle neck diameter, although it is more preferably approximately equal to one and one-third the inside bottle neck diameter.
  • an anchor head having a diameter equal to or preferably greater than approximately one-half the inside bottle neck diameter, although it is more preferably approximately equal to one and one-third the inside bottle neck diameter.
  • One embodiment uses a multipart anchor, and more preferably a two-part anchor which allows bottling to be performed without the need for additional bottling steps and/or new machinery.
  • the use of two-part anchors can shift the risk of application failures from winery bottling lines to a smaller set of cork preprocessors and perhaps distributors, because the anchor is joined to the compliant stopper portion before delivery to the bottling line where the stopper with anchor is inserted into the bottle.
  • the two-part anchor comprises a shank member for retaining a compliant layer about the exterior of the shank.
  • the shank is configured for attachment to a head member capable of receiving an axial stopper extraction force in response to unthreading of a sleeve threadably engaged on the bottle neck.
  • the two-part anchor incorporates a radially symmetric or annular latch mechanism whereby the anchor head can be latched to the shank, after the shank is coupled to the compliant layer and inserted into the bottle.
  • the shank may be coupled to the compliant layer by threading it into a cork or other compliant material, molding the shank within a compliant material, or by additional means without departing from the teachings of the present invention.
  • the shank is configured for installation within a stopper, such as comprising a cork.
  • the shank is an elongated frame structure upon which an elastic material is joined (i.e. molded), wherein the combination forms an anchored stopper.
  • the head member preferably comprises an annular member disposed above the sleeve for engagement by a portion of the closure capsule when rotated to effect stopper extraction.
  • An annular rib or lip, or other portion of the closure capsule is configured to engage the head member and apply an extraction force to the stopper.
  • the sleeve is preferably configured with internal threads which mate with external threads on the outer surface of the neck of the bottle, or another mating sleeve attached to the outer surface of the bottle.
  • means is provided for mechanically coupling the anchor shank and anchor head. Preferably this is performed in response to threading the closure capsule and its optional top cover, such as a reseal cap, onto the bottle after installing a stopper having an embedded anchor shank into the bottle. Pushing axially on the optional top cover or the anchor head while, rotating the capsule in relation to the bottle, causes axial pressure to be exerted on the annular head and the attached anchor shank and stopper.
  • the anchor head is thereby pushed onto the anchor shank where it is latched into place.
  • right-hand or left-hand threads on the bottle are substantially equivalent, although right-hand threads are preferred as they are more common which may reduce confusion when users attempt to open the bottle. It is preferred that, if right hand threads are used on the bottle and a threaded anchor shank is used, the shank threads be configured as left handed threads to prevent possible unscrewing of the shank due to friction between the sleeve and the anchor head when the sleeve is unscrewed.
  • This configuration of closure enables the consumer to easily apply a low-level torque that produces a well controlled pulling forces equivalent to those currently generated by auxiliary cork screws within a self- contained assembly that is readily and inexpensively manufactured and utilized by wineries and other bottlers, such as of wine or other fluids.
  • This closure method allows wine or other producers to utilize conventional natural or synthetic cork materials to assure proper sealing of the wine or other fluid being retained.
  • the present invention may be utilized with high-speed mechanized corking equipment typical to the industry, without introducing a new source of contamination.
  • anchorless natural or synthetic corks is also an aspect of the invention, wherein the cork is shaped so as to be engaged by the closure capsule. Methods are described for inserting anchorless corks into the bottle either before or after coupling of the closure capsule to the bottle.
  • corks similar in shape to traditional sparkling wine corks after deformation during bottle corking, may be engaged directly by the cork- removal sleeve, while substantially cylindrical corks may be adapted, such as with exterior recesses, for being engaged by the closure capsule.
  • Other embodiments of the invention use cork-free forms of closures, wherein a bottle with a threaded top is sealed with an elongated closure capsule in which a fixed or removable seal portion is retained.
  • the closure capsule provides the same appearance as a foil-wrapped bottle neck, but this form of closure provides an economic sealing alternative while overcoming the aesthetic shortcomings, and concomitant consumer resistance, of "screw-cap" bottles.
  • bottles utilized with the closure capsules of the invention are adapted with exterior threads to engage the interior of the sleeve of the capsule.
  • Preferred bottle adaptations include a recess below the threads, referred to herein as a "choke ring" to allow the bottle to be grasped by machine tools, such as during bottle manufacture.
  • the circumferential depression in the bottle neck forming the choke ring is utilized in place of the usual protruding ring that is needed to grasp the bottle during the molding process.
  • the upper portion of the bottle neck such as the corkage area, is preferably narrowed to accommodate the thickness of the sleeve portion of the capsule so that the exterior of the threaded-on capsule conforms to the contours of the bottle making it appear as a generally conventional bottle wrapped with a foil wrapper. It will be appreciated that traditional bottle necks have an outside diameter generally exceeding one inch
  • the interior at the base of the capsule is preferably tapered to conform to the transition in bottle diameter leading into the narrowed portion of the neck.
  • the closure capsules provide mechanical leverage that allow removing bottle corks, or other stoppers, easily and controllably. Threads on the sleeve portion of the closure capsules enable the conversion of a manual torque (e.g., approximately 20 pound-inches or less) applied to the capsule to deliver an axial force (e.g., up to approximately 100 pounds of force) for extracting a cork, while minimizing the number of turns of the capsule required to fully extract the cork.
  • a manual torque e.g., approximately 20 pound-inches or less
  • an axial force e.g., up to approximately 100 pounds of force
  • Another aspect of the invention relates to features that prevent inadvertent loss of seal integrity on closures and/or indications that the seal has been compromised, such as in the case of bottle tampering.
  • closure capsule rotation can be limited, such as by utilizing unidirectional protrusions, while retainers such as snap-rings or other mechanisms may be employed to serve as a latch.
  • tamper indications are preferably provided on all embodiments, such as through the use of a segmented capsule that separates when the capsule is unthreaded, engagements between the bottle and capsule that break or are overcome when the capsule is unthreaded, or frangible neck bands that break in response to twisting of the closure capsule.
  • Means for resealing the bottle after opening may be incorporated as an aspect of the present invention as well.
  • the resealing means may be implemented so as not to depart from the traditional appearance of the bottle, while providing a self-contained mechanism for resealing the contents, for example to prevent oxidation during storage.
  • a threaded nipple portion can be preferably provided for certain embodiments within which a threaded cap is received. It should be appreciated that the cap may be configured to snap or thread onto the bottle for sealing and may be attached to the sleeve when not in use by threading, snapping, or other removable retention means such as frangible bonds, material links or the like.
  • a secondary seal means is also described as an aspect of the present invention, wherein oxygen is prevented from reaching the retained fluid, such as wine, even if the stopper seal integrity were compromised.
  • Pressurized bottle sealing is also described in which the stopper cork is prevented from uncontrolled, and possibly explosive, egress from the bottle.
  • a two-piece cork anchoring apparatus and method is characterized by (a) a sleeve configured for threadable engagement about the neck of a bottle having exterior threads, (b) an anchor head adapted for being engaged by a portion of the sleeve, (c) an anchor shank configured for attachment to a bottle stopper, and (d) means for mechanical coupling of the anchor head to the anchor shank.
  • the stopper may comprise a natural or synthetic cork configured for being attached to an anchor shank, or an elastic material attached to an anchor shank configured as a frame for retaining the elastic material as a stopper.
  • the closure capsule is retained in contact with or proximal to the anchor head member. Rotation of the sleeve on the exterior bottle threads provides for engaging the anchor head member to apply force required in removing the stopper in response to the sleeve being unscrewed from the bottle.
  • the shank and head portions of the anchor may be joined in various ways such as utilizing mating connectors, (i.e. press-fit connectors), which preferably engage in response to the application of a sufficient engagement force (i.e.
  • this second level of force required to disengage the shank and head should be at least approximately fifty pounds, even for small corks. More preferably this second level of force should be within the range approximately fifty pounds to approximately three hundred pounds of axial force for bottles with inserted sealing plugs.
  • At least one protrusion on one member is received into at least one mating aperture in the other member.
  • the members may include circumferential adaptations, such as slots, grooves, or the like, as a means of moderating engagement forces when attaching the shank to head.
  • One or more ribs are preferably included on these members to accommodate a range of cork insertion depths into the bottle, typically approximately two tenths of an inch (0.2 inch).
  • Anchor shanks configured for insertion into natural or synthetic corks are preferably configured with means for automated engagement of the anchor shank by an automated insertion machine which allows the anchor shank to be automatically inserted into a stopper.
  • Such means may be implemented using a mechanical engagement structure, such as a recess or protrusion (i.e. polygonal) on the upper portion of the shank member which is configured for urging the anchor shank into a stopper by automated mechanisms.
  • a flange may be incorporated extending from the upper periphery of the anchor shank to control the depth of insertion of the anchor shank within a stopper.
  • the two piece, or multielement, anchor assembly makes possible a method of sealing a bottle with a removable stopper, which comprises: (a) inserting an anchor shank within a stopper configured for being inserted within the neck of a bottle for sealing the contents of the bottle, (b) inserting the stopper and retained anchor shank (with or without compression) into the neck of the bottle, (c) threading a capsule assembly onto the neck of the bottle, wherein the capsule has a threaded sleeve and a retained anchor head configured for engagement of the anchor shank, and (d) joining the anchor head of the capsule to the anchor shank by threading down the capsule onto the neck of the bottle whereby the bottle may be subsequently opened by threading the capsule assembly up off of the bottle neck to supply
  • the anchor head is joined to the anchor shank by mechanically engaging at least one protrusion with at least one mating receptacle, for example protrusions which extend down from the head engage receptacles in the shank, or the converse receptacle-protrusion arrangement, or the use of similar coupling mechanisms.
  • the closure capsule generally surrounds a portion of the bottle neck to provide a foil- wrapped appearance, or may be alternatively styled according to other desired aesthetics.
  • the lower portion of the closure capsule is configured for being threaded down into a recess in the neck of a bottle onto which it is received, wherein a desired shape transition can be obtained between the bottle and the closure capsule, such as that of providing a foil-wrapped appearance.
  • An upper portion of the closure capsule includes an engagement structure positioned for engaging the anchor head, preferably from underneath, although it may less preferably engage the head member from the sides or the top.

  • this aspect of multipart anchoring provides important benefits over the insertion of one-piece anchors into stoppers during bottling, such as at a winery.
  • multipart anchoring removes a higher risk operation out of the bottling line and puts it where tighter controls and better quality can be maintained, and in which much higher failure rates can be tolerated.
  • the use of multipart anchors substantially reduces requirements for modifying bottling lines and purchasing additional equipment at the bottling facilities.
  • a stopper with pre-inserted anchor shank is compressed and installed to seal the bottle.
  • An anchor head (of one or more elements) is afterward secured onto the anchor shank, such as part of a closure capsule.
  • Another advantage of this multipart approach is that the anchor head, with optional reseal cap, can be preassembled into a closure capsule that can be applied to the corked bottle on the bottling line in a single operation where the closure capsule assembly is simply twisted down onto the bottle neck upon which the anchor head latches onto the anchor shank.

  • Type B anchors are to be generally applied as follows. An anchor- shank 22 is driven into a prepared stopper, typically a cork stopper, (such as having an appropriately sized aperture created for receiving the anchor shank and optionally inserting a sealing liquid or gel) to create a stopper that is ready for use during bottling.
  • Anchor-shank 22 may be driven into the stopper utilizing drive coupling 42 or other drive coupling means. It is preferred that preparation of the stopper with the anchor-shanks is a side operation, not to be performed on the bottling line.

  • Type B anchors A number of benefits can be derived from the use of Type B anchors, including the following, which are provided by way of example: the reduction of components to be installed on the bottling line from three separate items for a Type A anchor, to just one assembly of components for a Type B anchor, and the reduction in the necessary application equipment required at the bottling facility (i.e. winery) from three new machines for installing Type A anchors to just one new machine needed to install Type B anchors on the bottling line. It is contemplated that the use of Type B anchors prepared outside of the bottling line, such as by third-party stopper suppliers, can raise the overall confidence level with utilizing this form of bottle closures and shift the risk of application failures from winery bottling lines to stopper suppliers.

  • Cap 190 is shown formed from plastic, although it may be alternatively formed as a wire cage, netting, or any other convenient form capable of retaining the stopper from uncontrolled egress. As the closure is rotated and the stopper is pulled out of the bottle, the capsule remains engaged with the bottle. Permanent retention of cap 190 onto capsule 180 results in holding the stopper in place on the bottle during storage and prevents accidental removal of the cap, which would otherwise allow uncontrolled explosive stopper egress from the bottle. [00200] It should be appreciated that cap 190 may alternatively be removably retained on capsule 180, such as for use as a reseal cap. To assure controlled stopper egress it may be beneficial to prevent the user from removing cap 190 from capsule 180 prior to removal of capsule 180 from bottle 172.
  • Capsule 180 may be configured with a means to lock cap 190 in place until the stopper is removed, such as utilizing a compression mode which applies an outward radial pressure when capsule 180 is threadably engaged on bottle 172 to engage vertical ridges peripheral to cap 190 with vertical ridges within the recess 192 of the capsule.
