Definitions

  • the present invention relates to a means for closing and sealing a bottle for containing a liquid, which container comprises a neck, a rim of the neck and a lid.
  • Closing means for bottles are known from the prior art. Glass bottles are generally sealed with a cork, a plastic cap or a screw cap. Glass bottles containing beer or other carbonated beverages are generally sealed with a metal closure that is crimped around a groove that is a feature of the outer neck of the bottle.
  • the commonplace form of this closure device is the crown cork, which is a pressed steel disk formed with a skirt of 21 tines.
  • Carbonated beverages may also be contained in plastic bottles, generally made from polypropylene (PP), polyethylene terapthalate (PET) or polyethylene naphtalate (PEN).
  • the closure devices of these plastic bottles are usually screw caps, which are screwed on a threaded neck of the bottle.
  • the glass container according to the present invention comprises a neck, an opening and a cover member closing off the opening, characterised in that the cover member comprises a contacting surface, comprising a rigid material, that is adhesively attached to the neck.
  • the rigid material, such as ceramic, plastic or metal, of the cover member is compatible with the glass of the container, and can be subjected to the same conditions of temperature and pressure, for instance during pasteurisation, without adverse effects.
  • the combination of the rigid material cover in combination with the adhesive attached was found to form a very good barrier, in particular against carbon dioxide diffusion out of the container, containing a carbon dioxide containing beverage, in particular beer.
  • the material of the cover member is glass.
  • the rigid cover member is compatible with an adhesive material that seals the area between the cover member and the neck, prevents oxygen from diffusing into the bottle and prevents liquid and/or gaseous contents, such as for instance carbon dioxide from escaping from the container.
  • the tensile strength between the cover member and the neck increases with the bond surface, but the shear strength remains largely unaffected, allowing the cover member to be slid off easily. In that way an easy opening of the rigid cover member by sideways force is combined with a large closing force perpendicular to the contacting surface of the neck.
  • the adhesive can take up a shear force substantially parallel to the contacting surface which is lower than the force perpendicular to the contacting surface that can be taken up by the adhesive.
  • the perpendicular force is between 2 and 10 times larger than the shear force, the perpendicular force being between 1 and 10 kg/cm 2 , preferably between 5 and 10 kg/m 2 .
  • This is especially suitable for carbonated beverages such as beer.
  • the pressure at normal serving temperature of 6 to 8°C is approximately 1 - 1.2 atmospheres, while during the pasteurisation process, at a temperature of approximately 60°C, the pressure is approximately 6 - 7 atmospheres.
  • the adhesive used in the present invention has a strong holding power during storage and pasteurisation and while the bottle is easy to open by the consumer by applying a sideways shear force.
  • the glass bottle has preferably a cover member which has as its sealing side a substantially flat disk-like surface, substantially in line with the neck.
  • the sealing side according to the present invention fits over the bottle neck of standard bottles. It is easy to remove by the consumer, because of the light shear force that has to be applied to move the glass disk. The disk is not projecting beyond the perimeter of the neck, to prevent the disk from being removed accidentally.
  • the cover member comprises a lever element which extends laterally beyond the contacting surface of the neck. It provides leverage to the tensile force that is needed to remove the cover member from the bottle. By use of the lever element the momentum created by the applied force is increased, so that the tensile force in the contacting surface can be overcome easily.
  • the bonding strength of the adhesive is higher at a temperature above
  • the adhesive has a transition temperature that is above the normal serving temperature of the carbonated beverage.
  • the transition temperature of the adhesive is in between the normal serving temperature of the beverage and the normal pasteurisation temperature, such as between 5°C and 100°C, preferable between
  • the closure device is easily to be opened at serving temperature and hard to be opened during the pasteurisation process.
  • the bond strength of the adhesive varies between a low bond strength, such as 3 kg/cm 2 or lower at serving temperature and a high bond strength at higher temperatures, for example the pasteurisation temperature, which usually takes place at 60°C to 65 °C, such as 80 kg/cm 2 or higher.
  • the cover member has undergone a surface treatment, for example such as with a chemical adhesive promotor, to increase the bond strength of the adhesive to the cover member.
  • a surface treatment for example such as with a chemical adhesive promotor, to increase the bond strength of the adhesive to the cover member.
  • the glass contacting surface of the cover member can be rougher than the glass contacting surface of the neck. This can for instance be achieved by etching, sanding or applying chemicals to one or both contacting surfaces.
  • the glass bottle comprises a hot-melt or UV-cured adhesive on the cover member, which adhesive is being cured to a larger degree than the adhesive on the bottleneck.
  • a hot melt adhesive that can be used is for example an atactic polypropylene hot melt obtained from Norcross Adhesives Limited, Longton Road, Trentham, Stoke-on-Trent ST4 8JB, England.
  • UV-cured adhesives such as for example Loctite 358, can be obtained from Loctite UK Limited, Watchmead, Welwyn Garden City, AL7 1JB, England.
  • the same effect can also be achieved by the use of two different adhesives, which consist of a first type covering the contacting surface of the cover member and a second type covering the neck.
  • the bonding strength of the first adhesive is larger than the bonding strength of the second adhesive, so that the adhesive will stick to the cover member after opening of the bottle.
  • the used adhesives can be a hot melt, a UV-cured , or a combination of both types.
  • Fig. 1 shows a perspective view of the closure device according to the present invention
  • Fig. 2 shows a underside of the detached glass disk, containing the remaining adhesive material
  • Fig. 3 shows the underside of a second embodiment of the glass disk according to the present invention.
  • Figure 1 shows a perspective view of the closure device 1 according to the present invention. It shows a bottle 2, comprising a neck of the bottle 3, and a rim 4 around the opening of the neck.
  • the closure device 1 is in the form of a glass disk 1.
  • the side 6 of the glass disk 1 is connected to the rim 4 by use of an adhesive (5, shown in fig. 2 and fig. 3).
  • the glass disk can be removed from the neck of the bottle by applying a force on the side 8 of the glass disk 1.
  • the adhesive between the rim 4 of the neck and the side 6 of the glass disk 1 will fail due to the applied shear force.
  • Figure 2 shows an underside of the detached glass disk 1, containing the remaining adhesive material 5 after removing the glass disk 1 from the bottle 3.
  • the adhesive material 5 stays attached to the glass disk 1.
  • Figure 3 shows the underside of a second embodiment of the glass disk according to the present invention.
  • the glass disk 1 contains a lever element 10 to ease the opening of the bottle 3, attached to the side 8 of the glass disk 1.
  • the glass disk 1 shows a protruding part 9, which protrudes from the underside of the side 6 of the glass disk 1 and fits into the opening 11 (figure 1) of the bottle. This protruding part prevents the glass disk from being moved freely in de plane of the adhesive material 5

Abstract

L'invention porte sur un réceptacle (2) en verre comprenant un goulot (3), un orifice (11) et un bouchon (1) fermant l'orifice. Ce réceptacle se caractérise en ce que le bouchon comprend une surface de contact rigide, fixée de manière adhésive au goulot. Le réceptacle en verre peut s'ouvrir facilement en surmontant la contrainte de cisaillement dans le plan du matériau adhésif, et cela en retirant le disque de verre par coulissement. Ceci peut être effectué au moyen d'un adhésif thermofusible ou d'un adhésif séché par rayonnement ultraviolet.
