Definitions

  • the present invention relates to carbonated beverage containers, and particularly relates to containers for supplying beverages to consumers.
  • the invention has particular utility for the storage and supply of carbonated and other sparkling drinks, but may also be used with other types of drinks.
  • a first aspect of the present invention provides a beverage container comprising a container body including an opening and removable closure means for closing said opening, the closure means comprising a cap for covering the opening, the cap having an over-centre mechanism moveable between an unsecured position and a secured position.
  • the over centre mechanism preferably comprises an annular skirt portion depending from the cap, the skirt being moveable between a first position which enables the cap to be fitted onto the container body and a second position which secures the cap to the container body.
  • the skirt portion may be flipped from an upper, stable position to a lower, stable position.
  • one area of the skirt portion may be pressed down by a force applied thereto to the lower position and then the remainder moved down as said force is moved around the circumference of the skirt portion.
  • the annular skirt portion is located beneath an external lip or projection on the container body when in the second position.
  • the lid is pulled down tightly against the container body by such action.
  • the annular skirt portion is attached to the cap by a living hinge.
  • the annular skirt portion may comprise a plurality of relatively stiff portions arranged to locate beneath a rim of the container, the stiff portions being connected by relatively flexible portions.
  • a tab and/or weakened portion is preferably provided in the annular skirt portion to enable the annular skirt portion to be broken to release the cap from the secured position.
  • the closure means includes a foil for sealing the opening, the cap being fitted to the container body over the foil.
  • the foil is attached to the cap so the cap and foil can be removed from the container body together.
  • the foil may be attached to the cap by heating the foil, e.g. by induction heating, to melt a plastics layer on the foil whilst it is held in contact with at least part of the cap.
  • Such methods for attaching a foil are well-known in other applications.
  • the foil may be attached to the container around a perimeter of the opening, e.g. by induction heating.
  • the attachment to the container whilst being strong enough to withstand the desired level of pressure within the container, is weaker than the attachment to the cap so that upon removal of the cap, the foil is separated from the container but remains attached to and is removed with the cap.
  • the foil may not be attached to the container but seals the opening thereof by simply being held in contact with or pressed onto the container by the cap.
  • references to foil herein are to be understood to refer to a thin membrane and includes impervious laminates comprising one or more layers which give the foil strength and one or more layers for attaching the upper and/or lower surface of the foil to another article.
  • Such foils are widely used in other fields.
  • an electrically conductive layer is required. This is usually a metallic layer and most commonly a layer of aluminium.
  • the electrically conductive layer is typically provided with one or more plastic coatings, e.g. of polyethylene, which melt when the electrically conductive layer is heated to bond the foil to an article held in contact therewith.
  • plastic coatings e.g. of polyethylene
  • the container is typically formed of a plastics material, e.g. polyethylene terephthalate (PET), or of glass.
  • PET polyethylene terephthalate
  • the container is preferably shaped to resemble a conventional drinking vessel, e.g. a beer glass.
  • the cap preferably provides physical support for the foil, e.g. by limiting the extent to which it can be distorted by pressure increases within the container and/or by reinforcing the connection between the foil and the container.
  • the cap may be generally circular so it lies over the perimeter of the foil around the periphery of the opening and thus assists in holding the foil in contact with the container. In some cases this may also provide sufficient obstruction to limit bowing out of the foil due to internal pressure but, preferably, the cap extends across the entire foil both to provide further obstruction to deflection of the foil, particularly at the centre thereof, but also to protect the foil against damage from physical contact with external objects which might puncture the foil and/or reduce its integrity.
  • the cap thus strengthens and/or protects the connection of the foil with the container and provides puncture protection for the foil.
  • the cap may be made from a range of materials but is preferably formed from a plastics material such as polypropylene (PP) or polyethylene (PE) and may be formed by injection moulding.
  • PP polypropylene
  • PE polyethylene
  • Venting means are also preferably provided to allow pressure within the container to be vented prior to complete removal of the cap and/or the foil. If the foil is attached to the container controlled venting may be provided as the foil is peeled off the container.
  • the foil is preferably secured to the container in a manner capable of withstanding internal pressures of 1 - 2 bar or greater (as might arise if a carbonated drinks container is subject to high temperatures), e.g. up to about 6 bar. As well as preventing the egress of gas, the foil also protects the container from ingress of gas, so helps prevent contamination of the beverage and prevent it becoming stale. With such a foil, the beverage container can have a shelf-life of at least 9 months (as typically required for beers and other carbonated drinks sold in containers).
  • the foil is removed with the cap and remains bonded thereto as the cap is removed.
  • the cap may be re-used after removal to cover the opening, e.g. by snap-fitting onto the container, to prevent spillage and preserve the freshness of the beverage.
  • the foil may provide tamper evidence in that if the foil is intact it provides the consumer with reassurance that the product has not been tampered with or previously opened. This function is further enhanced if the cap is formed of a transparent material.
  • tamper evident means are provided on the closure means to provide visual indication as to whether the closure means has been opened or tampered with.
  • the tamper evident means preferably comprises a frangible portion of the cap, e.g. of the annular portion, which is ruptured when the cap is loosened or removed.
  • the closure means may be arranged to provide venting of the container as it is removed from the container. Venting preferably occurs in a controlled manner upon initial movement of the cap and before the cap is free to be removed (so as to avoid missiling of the cap). Controlled venting may be provided by piercing the foil prior to it being removed and/or as the foil starts to be peeled off the container.
  • the foil may need to be strengthened to increase its puncture resistance and/or a protective component, e.g. a cardboard disk, which extends over the upper surface of the foil may be trapped between the foil and the cap.
  • a protective component e.g. a cardboard disk
  • the cap preferably covers the upper periphery of the foil as well as extending around the external surface of the container.
  • the foil also preferably has a skirt portion which extends over the external surface of the container adjacent its opening and is preferably crimped in place, e.g. under a lip of the container. The annular portion of the cap may assist with the crimping and/or assist in holding the skirt of the foil in place.
  • the opening of the container body preferably is a wide-mouth opening.
  • a wide-mouth opening is meant (at least in its broadest sense) an opening of a size suitable for a person to drink from the container in the same manner as from a drinks glass or similar drinking vessel. That is, in its broadest sense, the wide-mouth opening of the container (for embodiments of the invention having a wide-mouth opening) generally renders the container suitable as a drinking vessel from which a beverage supplied in the container may be conveniently drunk (in contrast to conventional narrow-necked bottles and ring-pull cans which generally are not regarded as comfortable drinking vessels).
  • the diameter of the wide-mouth opening of the container will normally need to be at least 40mm, preferably at least 45mm, and more preferably at least 50mm. Additionally, an excessively wide opening is generally difficult for the consumer to drink from, and thus the wide-mouth opening preferably has a diameter no greater than 150mm, more preferably no greater than 100mm, and especially no greater than 80mm. A particularly preferred diameter range for the wide-mouth opening is 50 to 80mm, and examples of particular preferred diameters included 53mm and 63mm.
  • the invention is, however, also applicable to containers having a narrower mouth, e.g. in the form of a bottle.
  • the container body preferably has no projecting thread or thread segments on its exterior. Consequently, the container body preferably is comfortable for a consumer to drink directly from the container body.
  • the containers described herein may be used for other types of beverages
  • the invention relates to the storage and supply of carbonated and other sparkling drinks, for example beers, ciders, sparkling wines (including champagne), other fizzy alcoholic beverages, and non-alcoholic fizzy and sparkling beverages, including sparkling water and carbonated soft drinks.
  • closure means for a beverage container as described herein.
  • the invention relates to the use of a beverage container of the type described for containing a carbonated beverage and to a method of sealing such a container.
  • Figure 1 is a partial, perspective view of a first embodiment of a beverage container according to the invention
  • Figure 2 is a partial, vertical section through the container of Figure 1;
  • Figure 3 is a vertical section through a second embodiment of a beverage container according to the invention.
  • Figure 4 is a perspective view thereof showing the closure means prior to attachment to the container body
  • Figure 5 is a partial, perspective view thereof showing the closure means when secured to the container body.
  • Figure 6 is a partial, vertical section of the container shown in Figure 5.
  • Figures 1 and 2 show a container body 10 with a cap 11 shown in the closed position, and a foil 12 across the mouth of the container body.
  • the cap 11 comprises a generally circular top portion HA and an annular skirt portion 13 depending from the perimeter of the top portion HA.
  • the annular skirt portion 13 has an upper annular portion 13A connected to the top portion HA and a lower annular portion 13B connected to the upper portion 13A by means of a hinge 14.
  • the upper and lower annular portions 13A and 13B may be integrally formed with each other and the hinge formed by a relatively thin, flexible connection therebetween, e.g. in the form of a so-called Miving hinge'. This forms an over-centre mechanism which can be flipped from an upper stable position to a lower stable position as will be described further below.
  • the lower portion 13B comprises a projection 13C which is located under a lip 1OA of the container body to secure the cap 11 thereto.
  • the projection 13C may extend around the annular portion 13B or may comprise a plurality of projections spaced around the inner circumference of the lower annular portion 13B.
  • the lower portion 13B is stable in the position shown in Figures 1 and 2 as it extends around the perimeter of the container and any attempt to lift this portion requires its diameter to be increased and so is resisted by tension (hoop stress) arising in the annular portion 13B.
  • Figure 1 shows a tab 15 provided in the lower annular portion to enable a user to break the lower annular portion 13B in order to remove the cap 11 from the container body 10.
  • the tab 15 projects slightly to enable a user obtain a purchase thereon and is formed between two lines of weakness 16A, 16B such that a lifting force applied to the tab causes the annular portion 13B to tear along these lines.
  • Figures 3-6 show a second embodiment of a container according to the present invention comprising a container body 20 and cap 21.
  • Figures 3 and 4 showing the cap 21 prior to being secured to the container body 20 and
  • Figures 5 and 6 show the cap 21 in the secured position on the container body.
  • the cap comprises an annular skirt 23 with an upper and lower portions 23A, 23B connected by a hinge 24 but has a plurality of projections 23C on the inner surface of the lower portion 23B spaced therearound for locating in a series of corresponding recesses 2OA in the external surface of the container body 20.
  • the container body 20 does not have a projecting lip like that shown in Figure 2 but, instead has this series of recesses each of which includes a substantially horizontal surface under which the projections 23C are secured to hold the cap 21 on the container body.
  • a longer form of tab 25 is also shown in this embodiment.
  • the projections 23 may comprise thickened, relatively stiff areas of the lower portion 23B. These areas may be interconnected by relatively thin and hence more flexible areas of the lower portion 23B.
  • the lower annular portion 23B Prior to being secured to the container body 20, the lower annular portion 23B is in a "raised” position. In this position, the lower annular portion 23B projects upwardly from its connection with the upper annular portion 23A and is held in this position by tension therein which resists enlargement of the circumference of the end thereof remote from the hinge 24. In this position, the projections 23C are pivoted outwards about the hinge 24 so that the cap can be placed onto a container body (either by being a close fit thereabout or by means of a relatively loose snap fit onto the body 20).
  • the lower annular portion 23B can then be flipped down to its lower position as shown in Figures 5 and 6 (which also correspond to the position shown in Figures 1 and 2).
  • the projections 23C are then located within the recesses 2OA to secure the cap 21 to the container body.
  • the projections 13C, 23C are preferably designed so that as they rotate to engage with the container body when the lower annular portion 13B, 23B is rotated about the hinge connection to the upper annular portion 13A, 23A to the lower position, they act to pull the cap 11, 21 down tightly against the mouth of the container 10, 20.
  • annular sealing member 22 may be provided therebetween (this may, for example, be an annular piece of foil or a conventional O-ring).
  • a foil (12) may be provided across the mouth of the container (as in Figure 2). It a sealing member or foil is used, the cap helps maintain the seal this makes with the container.
  • annular portion 13, 23 has two stable positions, an upper position (as shown in Figures 3 and 4) and a lower position (as shown in Figures 1, 2, 5 and 6).
  • References to an over-centre mechanism herein are intended to refer to such a mechanism which can be moved between two stable positions.
  • the lower member portion is broken, e.g. by a tab 15, 25, so circumferential tension can no longer resist movement of the lower annular portion to the upper position.
  • part of the lower annular portion may be adapted to enable it to be lifted in one area by an upward force and then this upward force moved around the circumference thereof until the entire lower annular portion has been lifted to the raised position (this being the reverse of the action described above for securing the cap to the container).
  • One way of arranging this is to provide a drawstring which is pulled upwards at one point and then pulled around the cap so as to progressively lift the lower portion to the raised position.
  • the over-centre mechanism secures the closure to the container body and provides a force urging the closure into contact with the mouth of the container. This force may be used to help hold a sealing member or foil in sealing contact with the container mouth.
