Definitions

  • the present invention relates to a beverage bottle having a re-sealable closure and a method of applying and interlocking a re-sealable closure for a beverage bottle.
  • crown corks Metallic caps, generally known as crown corks, have been frequently used for sealing glass beverage bottles ever since their introduction in the late 19 th century.
  • Crown corks comprise a metallic cap having parts arranged for engagement with the external periphery of a neck or wall of the beverage bottle.
  • crown corks are applied onto standard glass bottles having an outwardly oriented bulge near the mouth of the bottle. The crown cork is clamped securely onto the bulge in order to withstand and seal the pressure within the bottle.
  • the generally known crown corks are made of thin metal sheet and have the advantage of being easy to manufacture, require a very small amount of material and they are easy to apply onto the mouth of the beverage bottle. Crown corks are also tamper evident, since once the crown cork is removed, it cannot easily be re-applied onto the bottle.
  • the original crown corks are described in US 468,226 and US 468,258 .
  • a common approach is to use a closure comprising a cap of flexible material which is held tightly in place on the mouth of the beverage bottle by a collar surrounding the cap. To open the closure, the collar is pulled off the bottle by hand, where after the cap is released.
  • the above idea is known as the pull collar concept.
  • the prior art includes numerous publications from several decades.
  • the pull collar concept may be defined as a closure comprising a cap encircled by a collar.
  • the cap has a skirt for encircling and engaging a flange on the neck of a bottle for retaining the closure to the bottle, and the collar is slidable along the axis of the cap from a first position, in which it allows the cap to be mounted on the bottle, to a second position in which the collar forces the skirt to engage the flange.
  • the skirt may engage an upper or a lower flange on the bottle neck.
  • the skirt it is understood that it may be constituted by a single piece or may comprise multiple axially directed tabs.
  • a more cap-like closure is known from US 1,758,696, published in 1930 , in which a collar is axially moveable from a first "open” position, to a second "locked” position.
  • a simple implementation is shown in GB 44 66 12, published in 1936 , in which a collar is mountable on the cap to force the sides of the skirt to engage the flange on the bottle neck.
  • Similar closures are also known from US 2,659,511, published in 1953 , and US 2,814,405, published in 1954 .
  • a closure comprising several components is disclosed in US 2,576,580, published in 1951 , wherein a collar is axially moveable in relation to a cap structure for selectively causing the legs to engage the flange of a bottle neck.
  • further variants include features related to the collar or outer cap being initially attached to the cap in an "open” position, allowing the closure to be easily applied to the container before the attachment is broken, when the collar is forced into the "locked position", see for the closure disclosed by US 5,085,332, published in 1992 .
  • EP 1 121 300 discloses a bottle security device comprising an outer cap and an inner cap and a mechanism for preventing the inner cap from being removed from the outer cap.
  • EP 747 293 discloses a vial and a crimp top seal. A collar may be mounted on the crimp top seal to further increase the contact between the crimp top seal and the neck of the vial along contact lines.
  • EP 655 042 discloses a two-piece all plastic seal having an inner cap and an outer cap, the inner cap having a slit skirt.
  • EP 2 051 912 discloses a bottle closure for high pressure liquids, the closure comprising a first part for engaging the neck of the bottles, and a second part moveable from a locked to an open position for selectively influencing the first part.
  • the second part further includes a lower section 48 for further engaging the bottle neck.
  • EP 1 186 546 discloses a device for closing bottles, in which device a sleeve is axially moveable to force tabs into engagement with the flange of a bottle neck.
  • EP 696 994 discloses a bottle cap in which a collar is moved axially upwards as the cap is pressed down, the collar thus causing the tabs to engage the flange of the bottle neck.
  • WO 2011/022756 discloses a closure which comprises an outer cap and an inner cap having tabs, the outer tab having cams allowing the outer cap to be moved axially in relation to the inner cap by application of an axial force, or by turning the outer cap.
  • the outer cap further includes a frangible component for further engaging the bottle neck.
  • EP 2 344 397 discloses a closure for a bottle, the closure having an inner part having tabs for engaging the bottle neck and an outer part axially moveable with respect to the inner part for selectively forcing the tabs of the inner part to engage a flange on the bottle neck.
  • the parts further include raised portions for preventing rotating of the parts in relation to each other.
  • EP 1 632 439 discloses a cap having an outer cap comprising a sleeve and tabs for engaging a flange on a bottle neck to retain a stopper in the opening of the bottle.
  • caps with slit skirts are known from US 5,960,972, published in 1999 .
  • An outer part having a bottom edge for engaging a lower edge of an inner cap is found in US 2003/0168456, published in 2003 , wherein a partly tapered outer cap has a bottom edge for engaging the lower edge of an inner cap having tabs.
  • WO 2011/039400A1 published in 2011 , discloses a cap having a skirt with an inner projection, the outer surface of the skirt having a corresponding external depression. The reasoning behind this feature, according to the patent publication, is that the amount of material needed for the manufacture of the cap is reduced.
  • US 5,615,788, published in 1997 discloses a pull collar styled closure having a paper seal provided on the top, i.e. connected to both the collar and the cap, see the figure below. The paper seal is perforated.
  • the closure may be applied by a simple downwardly oriented pressure force, i.e. no clamping action is required.
  • the opening may consequently be performed by a simple upwardly oriented force without the use of a bottle opener.
  • a beverage bottle having a re-sealable closure comprising a body, a cylindrical neck connected to the body and a mouth connected to the neck opposite the body and defining an opening, the mouth comprising an outwardly oriented bulge at a fist axial distance from the opening, the bulge defining a first outer periphery at the first axial distance, the closure comprising:
  • the beverage bottle is a standard bottle having a body intended to accommodate the beverage, typically in an amount of between 25cl and 1 litre, and a neck leading to the mouth and the opening of the bottle.
  • the outwardly oriented bulge is typically rounded and defines a circumference larger than the neck and defines a "saddle" between the bulge and the neck.
  • the first outer periphery is understood to be the largest periphery of the bulge and is located at an axial distance from the opening.
  • the neck may optionally define further bulges below the bulge closest to the opening, which bulges may be used for other purposes such as fastening a tamper evident ring.
  • the cap covers the opening and seals the opening in relation to the outside environment.
  • the circumferential skirt extends the second axial distance from the opening to a location below the first periphery such that the skirt may interlock with the outwardly oriented bulge at the "saddle" between the outwardly oriented bulge and the neck.
  • the corrugation of the skirt typically extends in an axial direction and the third periphery corresponds to the innermost periphery, i.e. the innermost extreme points of the corrugation, and the fourth periphery corresponds to the outermost periphery, i.e. the outermost extreme points of the corrugation.
  • the number of corrugations is typically between 10 and 40, such as 20.
  • the number of axial slots typically coincides with the number of corrugations.
  • the width of each slot should be sufficient for allowing the skirt to be bent between the uncompressed state and the compressed state without plastically or permanently deforming the skirt.
  • the skirt In the uncompressed state the skirt is capable of being pressed over the bulge.
  • the skirt thereby flexes in an outwardly direction, i.e. the uncompressed state may imply some outwardly oriented flexing of the skirt.
  • the "neutral" state of the skirt is having a larger inner periphery than the outwardly oriented bulge.
  • the cap is accommodated in the inner space of the collar.
  • the disc of the cap When the collar is applied onto the mouth of the beverage bottle, the disc of the cap will cover the opening of the mouth and the skirt of the cap will enclose the third periphery of the outwardly oriented bulge of the mouth in the uncompressed state.
  • the collar may thereafter be pushed downwardly towards the bottle.
  • the inner surface of the upper section is defining a circumference which is smaller than the disc such that when pressure is applied onto the upper section, thereby limiting the distance which the collar may travel in the downwardly direction, thereby preventing the collar from slipping off the cap.
  • the inwardly oriented protrusion compresses the skirt to the compressed state in which the skirt interlocks with the bulge.
  • the inwardly oriented protrusion should define a periphery being larger than the second periphery of the disc in order to be able to encircle the cap, but smaller than the fourth periphery of the skirt in order to be able to compress the skirt such that the skirt interlocks with the bulge.
  • the groove and protrusion are corresponding which is understood to mean that they are of substantially identical geometrical configuration.
  • such identical geometrical configuration has the advantage of being very simple to manufacture, e.g. by using a material sheet of uniform thickness and establishing a dent in the material.
  • the user may grip around the circumferential groove and lift the collar upwards, i.e. away from the bottle.
  • the protrusion will then move upwardly and rest around the disc and the skirt will reassume its uncompressed state.
  • the user may then remove the closure from the mouth of the bottle.
  • the closure is in the open state, i.e. when the skirt is in the uncompressed state, the lower section of the collar bears against the skirt from below in order to list the cap off the mouth of the beverage container. In this way the cap is contained within the inner space.
  • the lower section may thus define a periphery being larger than the second periphery of the disc, but smaller than the fourth periphery in the uncompressed state such that the collar fits over the mouth of the beverage bottle.
  • the groove constitutes a circumferential groove and the protrusion constitutes a circumferential protrusion corresponding to the circumferential groove.
  • the circumferential groove constitutes a rolled groove.
  • a circumferential groove may advantageously be made by rolling.
  • the groove constitutes one or more detents.
  • Detents may be used as an alternative to the circumferential groove.
  • the detents may be flexible in order to adjust the level of compression.
  • the detents are preferably punched out of the intermediate section and form a taper away from the upper section.
  • the one or more detents define a fifth periphery being smaller than the second periphery of the disk, the collar being capable of assuming an initial state, in which the fifth periphery is bearing against the disc.
  • the detents may have a lower end which is slightly tapered towards the upper section in order to be able to pass the disc.
  • the cap is made of metal.
  • Metal is preferred in order to achieve a sufficiently strong corrugation which is not deformed or at least not critically deformed during closing of the seal.
  • the collar is made of metal. Metal is preferred in order to obtain a minimum of creeping.
  • the inwardly oriented surface and the outwardly oriented surface are tapered in a direction towards the disc. A taper towards the disc or upper section will make the closure easier to apply and will allow for an even larger tolerance of the first periphery of the bulge.
  • the taper is between 1 and 10 degrees, preferably between 2 and 7 degrees, more preferably between 3 and 5 degrees, such as 4 degrees. 4 degrees will allow a difference in the first periphery of 1.75 mm.
  • the cap is exhibiting the mouth to a pressure of about 0.1-1 bar, such as 0.5 bar, and, with the collar, the cap is exhibiting the mouth to a pressure of between 5 and 10 bar, such as 8 bar.
  • the pressure of the skirt against the mouth in the closed position is sufficient to keep the closure sealed to the pressurised beverage bottle.
  • the pressure within the bottle will typically escape.
  • the bottle is made of glass.
  • Glass is a rigid material which is recyclable and thereby environmentally friendly. Glass is alos very rigid and capable of holding pressurized beverages.
  • the friction force between the cap and said collar amounts to between 5 and 50N, preferably 10-40N, more preferably between 20 and 30N, such as 25N.
  • the friction force between the collar and the cap should be sufficient to avoid the collar from being lifted accidentally when the bottle is handled, and sufficiently small for allowing elderly people to open the closure without too much effort.
  • the upper section comprises an annular ring or a disc.
  • the upper section may preferably be constituted by an annular ring or disc in order to establish the inner surface which is able to contact the disc and an outer surface which is capable of showing a commercial message such as a brand name.
  • a re-sealable closure for a beverage bottle comprising a body, a cylindrical neck connected to the body and a mouth connected to the neck opposite the body and defining an opening, the mouth comprising an outwardly oriented bulge at a fist axial distance from the opening, the bulge defining a first outer periphery at the first axial distance, the closure comprising:
  • the above method according to the second aspect may be used to manufacture the beverage bottle according to the first aspect.
  • a re-sealable closure for a beverage bottle comprising a body, a cylindrical neck connected to the body and a mouth connected to the neck opposite the body and defining an opening, the mouth comprising an outwardly oriented bulge at a fist axial distance from the opening, the bulge defining a first outer periphery at the first axial distance, the closure comprising:
  • the above method according to the third aspect may be used as an alternative mode to manufacture the beverage bottle according to the first aspect.
  • the collar is rolled after the closure has been applied.
  • the inwardly oriented protrusion may be formed to optimally fit each bottle thereby overcoming any differences between the first peripheries of the outwardly oriented bulges of different bottles.

  • the slots 20 are located at the outer periphery of the skirt 18.
  • the corrugations of the skirt define an inner periphery and an outer periphery.
  • the present skirt is divided into an upper skirt part 22 adjacent the disc 16 and a lower skirt part 24 and only the lower skirt part 24 is corrugated.
  • the skirt is resilient between a compressed state and an uncompressed state.
  • the collar 12 defines an upper section 26, an intermediate section 28 and a lower section 30, which together are adapted to form an inner space to enclose the cap 14 while still allowing the cap 14 to move axially within the collar 12.
  • the upper section 26 defines a periphery which is smaller than the periphery of the disc 16 such that the disc 16 cannot pass through the upper section 26.
  • the intermediate section 28 is generally cylindrical and has an inner periphery larger than the outer periphery of the skirt when in uncompressed state, but comprises a rolled groove 32 which defines a periphery which is smaller than the outer periphery of the skirt 18 when in uncompressed state, but larger than the outer periphery of the disc 16 such that the rolled groove 32 may compress and uncompress the skirt 28 when the collar is moved axially towards and away, respectively, in relation to the skirt 16.
  • the collar further comprise a lower section 30 which defines a periphery which is smaller than the outer periphery of the skirt 18 when in uncompressed state but larger than the bulge of the beverage bottle (not shown) such that the collar 12 fits outside the mouth of the beverage bottle (not shown), but the cap 14 may be removed together with the collar 12.
