Definitions

  • the present invention relates to closures for sealing an opening.
  • the present invention relates to a sealing member for a closure used in the sealing of wine bottles and other bottled beverages.
  • Screw caps are a common form of closure employed to seal a large range of containers such as plastic and glass bottles for liquids including beverages ranging from soft drinks to wine.
  • screw caps are generally made of aluminium and have now become increasingly popular as a replacement for the traditional cylindrical cork due to concerns about cork taint and variability of quality of cork material which can lead to a poor seal and the associated premature oxidation of wine. While initially screw caps were associated with budget wines they are now commonly used for the packaging of premiums wine due to their inherent reliability.
  • Screw cap 100 consists of an outer sleeve 1 10 formed of a malleable aluminium alloy which is rolled on to the opening 250 of bottle 200. Screw cap 100 further incorporates a wad or liner 120 which seats within the roof of the screw cap 100 and which forms a seal against the rim 220 of the bottle or container 200.
  • Wad 120 may be formed of any number of materials ranging from plastic such as polyvinylidene chloride (PVDC), cork, rubber or multilayer combinations of these materials.
  • PVDC polyvinylidene chloride
  • the sealing layer 130 of wad 120 is formed from PVDC.
  • Screw caps of the type illustrated in Figure 1 and more generally have the significant disadvantage that they are not suitable to seal a container containing a liquid that is at a high internal pressure.
  • many sparkling varieties of wine are sealed at high pressure and the screw cap is simply not able to withstand the internal pressure exerted by the contents of the bottle. Accordingly, it is then necessary to use traditional cylindrical corks with all of their associated disadvantages.
  • the present invention accordingly provides a sealing member for a closure, the closure for applying to an opening, the sealing member including: a cap portion for seating the sealing member in a roof portion of the closure; and a flexible skirt portion extending from the cap portion and operable to contact an inner wall region of the opening on application of the closure to the opening.
  • the opening is for a container of fluid.
  • the container for fluid is a bottle.
  • the container contains a pressurised fluid, and wherein the flexible skirt portion under the action of the internal pressure of the pressurised fluid is forced against the inner wall region to seal the opening.
  • the closure is a screw cap.
  • the sealing member further includes a peripheral skirt portion extending from the cap portion, the peripheral skirt portion operable to locate against the wall of the closure.
  • a receiving portion is formed between the peripheral skirt portion and the flexible skirt portion to receive a rim of the opening.
  • the peripheral skirt portion forms a secondary seal against the rim of the opening.
  • the sealing member is formed as a unitary body.
  • the present invention accordingly provides a closure incorporating the sealing member of the first aspect of the present invention.
  • the present invention accordingly provides a method for sealing an opening including applying a closure to the opening, the closure including a sealing member having a cap portion for locating the sealing member within the closure, the sealing member further having a flexible skirt portion extending from the cap portion arranged to contact an inner wall region of the opening on application of the closure to the opening.
  • the opening is of a container for a liquid.
  • the closure is a screw cap.
  • the closure is roll formed onto the opening of the container.
  • the sealing member further includes a peripheral skirt portion extending from the cap portion, the peripheral skirt portion operable to locate against the wall of the closure when the closure is applied to the opening.
  • a receiving portion is formed between the peripheral skirt portion and the flexible skirt portion to receive a rim of the opening.
  • the peripheral skirt portion forms a secondary seal against the rim of the opening.
  • FIGURE 1 is a cutaway side view of a prior art closure in the form of a screw cap
  • FIGURE 2 is a sectional view of a sealing member for a closure according to a first illustrative embodiment of the present invention
  • FIGURE 3 is an underside view of the sealing member illustrated in Figure 2;
  • FIGURE 4 is a cutaway side view of the sealing member illustrated in Figure 2 in combination with the screw cap type closure illustrated in Figure 1 ;
  • FIGURE 5 is a sectional view of a sealing member for a closure according to a second illustrative embodiment of the present invention.
  • FIGURE 6 is an underside view of the sealing member illustrated in Figure 5;
  • FIGURE 7 is a cut away side view of the sealing member illustrated in Figure 5 in combination with the screw cap type closure illustrated in Figure 1 ;
  • FIGS 2 to 4 there are shown various views of a sealing member 300 for a closure 100 in accordance with a first illustrative embodiment of the present invention.
  • the closure 100 is a standard ROTE screw cap 100 as typically employed for wine bottles.
  • the present invention is applicable to the sealing of any general opening having a rim that a respective closure may be applied to.
  • Sealing member 300 includes a cap portion 310 which in this illustrative embodiment is a circular disc which seats in the roof of closure 100 (as best seen in Figure 4). Sealing member 300 further includes a flexible skirt portion 320 extending from cap portion 310. Skirt portion 320 is circular in shape to match the shape of the opening 250 of bottle 200 and suitably sized to contact the inner wall region 230 of the rim 200 of the opening of the bottle 200.
  • sealing member 300 is formed of PEARLTHANE ® 15N80 material which may be injection moulded as a unitary body. In another illustrative embodiment directed to higher pressure environments, sealing member is formed of PEARLTHANE ® 16N92.
  • sealing member 300 may form one layer of a composite liner or wad used in screw cap 100.
  • Closure 100 incorporating sealing member 300 is applied to the opening 250 of bottle 200 in the standard manner by pushing closure 100 onto the neck 280 of bottle 200 and then roll forming closure 100 onto the neck 280 using a standard roll forming process as is known in the art.
  • Flexible skirt portion 320 locates against the inner wall region 230 of the rim 220 of the bottle 200.
  • the internal pressure of the bottle or container forces the flexible skirt portion 320 against the inner wall region 230, thereby forming a seal between the sealing member 300 and the opening of the bottle 200.
  • screw cap closures incorporating a sealing member 300 in accordance with the present invention will seal bottle pressures up to 7.5 bar (750 kPa) which exceeds the degree of sealing required to seal sparkling wines such as champagne.
  • the applicant has also found that the degree of matching between the shape of the opening 250 of the bottle 200 and that of flexible skirt portion 320 need not be high as long as the skirt portion 320 initially contacts the inner wall region 230 of opening 250 upon application of the closure 100 to opening 250. This is due to the flexible skirt portion being forced against the inner wall region 230 of the opening 250 by the internal pressure of the contents of the bottle, thereby accounting for potential mismatches in the shape of the flexible skirt portion 320 and the opening 250.
  • Sealing member 300 also forms a more effective seal at low pressures where the sealing member acts as a static seal. This can be contrasted with the sealing effect at higher pressures where sealing member 300 functions to form a dynamic seal. Unlike the wad of prior art closures where the seal is broken if there is any upward movement of the wad, sealing member 300 is able to move upwards as a result of the pressure within bottle 200 and provided that flexible skirt portion 320 contacts the inner wall region 230 the seal will be maintained. Furthermore, the end of flexible skirt portion 320 which is being forced against the inner wall region 230 of opening 250 due to pressure within the bottle will also frictionally resist this upward movement, thereby further improving the reliability of the seal.
  • sealing member 400 is designed to be used in combination with a standard screw cap closure 100 of the type that is typically applied to a wine bottle or the like.
  • Sealing member 400 includes a cap portion 410, a flexible skirt portion 420 and a peripheral skirt portion 430 forming a receiving region 440 to receive the rim 220 of bottle 100.
  • the flexible skirt portion 420 flexes outwardly and sealingly engages with the inner wall portion 230 of rim 220 of bottle 200 due to the internal pressure of the contents of bottle 200.
  • Peripheral skirt portion 430 functions to further locate sealing member 400 by engaging with the top side wall portion of closure 100 and in addition, act as a secondary or backup outer seal by sealing against rim 220 of bottle 200.
  • the top of cap portion 410 includes a raised portion so that as the closure 100 is applied to the bottle, the cap portion 410 flexes in a concave manner pushing outwardly the flexible skirt portion 420 to engage with the inner wall region 230 of the rim 220 of bottle 200.
  • the sealing member of the present invention allows standard closures which otherwise would be unsuitable to seal containers containing liquid under pressure to be used in these circumstances. Furthermore, a closure incorporating a sealing member in accordance with the present invention is reusable in that the closure may be reapplied to the opening and the seal reestablished. While the present invention is described in relation to screw cap closures for wine bottles and the like it will be appreciated that the invention will have other applications consistent with the principles described in the specification such as plastic closures having a preformed internal screw thread as often employed with carbonated beverages.
  • a sealing member in accordance with the present invention may be used in combination with a NOVATWISTTM or similar type plastic cap where the conventional tin liner may be substituted with the sealing member described herein.
  • a plastic cap of this type may be used for containers containing a pressurised fluid having a standard screw thread arrangement such as the Bague Vin Canal (BVS) bottle finish that is typically employed for wine bottles.
