Definitions

  • One aspect of the present invention is concerned with an arrangement for controlling the axial displacement of a passage-producing means in a drinks container assembly of the first type.
  • the passage-producing means comprises a punch located in the gas reservoir and which is arranged to be urged towards the partition wall on the application of an external force to the central region of the first end wall, the first end wall being shaped and arranged such that once the first end wall has been pressed inwardly of the container assembly to a deflected position in which the punch has formed or opened the passage means, the central region of the first end wall is held in the deflected position by the rigidity of the material of the first end wall .
  • the popping action can help to displace the punch in a relatively controlled manner which is repeatable from one container assembly to another identical container assembly.
  • a second aspect of the present invention is concerned with a novel form of piercing plunger to constitute the passage-producing means.
  • the passage-producing means comprises a piercing plunger, the plunger being formed with a bore which extends from a piercing tip of the plunger to a communication port displaced from the piercing tip, the arrangement being such that when the plunger is urged against the partition wall the piercing tip pierces the partition wall, and the bore in the plunger provides the passage means which then provides communication between opposite sides of the partition wall.
  • the plunger is therefore akin to a hypodermic needle.
  • the plunger is preferably of tapered external shape such that it jams in the hole which it creates in the partition wall.
  • the passage-producing means comprises a plunger having a substantially parallel-sided first plunger portion which normally extends through an opening in the partition wall so as to seal the opening, and a second plunger portion so shaped that when the plunger is displaced inwardly of the container assembly from the normal position, to bring the second plunger portion into the partition opening, the second plunger portion defines with the partition wall said passage means extending through the partition wal1.
  • the second plunger portion is tapered and provided with a series of longitudinally-extending flutes, the taper providing an increased diameter of the second plunger portion in the direction away from the first portion.
  • the fluted and tapered second portion is urged partially through the partition opening, thereby enlarging the partition opening and defining a series of passages of predetermined dimension through the partition wall provided by the spaces between the flutes.
  • the plunger of the assembly in accordance with the third aspect may e secured at its outer end to the first end wall but preferably the plunger is not secured to the first end wall, the plunger being located in its normal position by an interference fit between the first portion of the plunger and the partition wall.
  • This arrangement has the advantage that the manufacturing step of securing the plunger to the first end wall is avoided.
  • the closure means may be a plug or plunger which is an interference fit in the partition opening.
  • the margin of the partition around the partition opening may be formed with a lip, and the closure means can then be a cap which is secured on the lip.
  • the method in accordance with the fourth aspect is applicable both to pressurised beer containers and to containers for mixed drinks.
  • the partition wall could be shaped and arranged to pop, as discussed hereinbefore in relation to the popping of the first end wall in accordance with the first aspect.
  • a drinks container assembly comprises a partition wall dividing the interior of a drinks container into first and second chambers of smaller and larger volume respectively, the partition wall being formed with an opening which is normally closed by a closure member, the co-operation between the closure member and the partition wall, and the pressure of the contents in the first chamber, being such that when a pouring opening is made in the container to vent the second chamber, the pressure in the first chamber is sufficient to unseat the closure member to permit fluid (gas and/or liquid) from the first chamber to enter the second chamber.
  • closure member becomes completely detached from the partition wall. This would generally be acceptable when the closure member is large enough, such as a ⁇ " diameter disc, not to pass through the pouring opening.
  • the closure means can therefore be arranged to unseal itself when the container is opened for pouring, without the need for the user to apply a force to open the closure means.
  • the container may have more than two chambers, adjacent chambers being sealed by a respective pressure-displaceable closure means.
  • Figure 1 is a vertical cross-section of a beer can having a poppable base, the initial position of the base being shown in full outline, and the popped position being shown by discontinuous lines,
  • Figure 2 is a cross-section of a similar can but showing a different configuration of base
  • Figure 3 is a vertical sectional partial view of a modification of the can of Figure 2
  • Figure 1 shows a drinks can which is particularly, but not exclusively, suitable for containing stout.
  • the can 1 has a substantially conventional external appearance, comprising a deep-drawn aluminium alloy side wall 2, a conventional top 3 provided with a ring-pull member 4 attached to an openable portion of the top 3, to enable a pouring opening to be provided on operation of the ring-pull 4 in the conventional way.
  • Base 7 has its margin 10 swaged to the lower margin of the side wall 2 which, in this example, is conveniently integral with a skirt 11 on partition wall 5.
  • chamber 6 contains pressurised gas, such as nitrogen, for initiating bubble development in the stout 13, which contains dissolved carbon dioxide.
  • pressurised gas such as nitrogen
  • ring-pull 4 is operated to open the pouring opening, and base 7 is popped by the user to initiate bubble formation in the stout.
  • the initial curvature of base 7, and its initial thickness and resilience, are chosen such that, once popped, the base 7 remains in the displaced position.
  • the tapered shape of the plunger 8 provides for firm jamming of the plunger 8 in the partition wall. Also, the tapered shape helps to avoid the production of an elongated hole in the partition wall 5 in the event that the plunger 8 is not positioned precisely centrally of the base 7 and, consequently, does not move precisely axially during popping.
  • Figure 4 shows a further container of similar construction to that of Figure 1 , and corresponding parts have been given corresponding reference numbers.
  • the upper end of the plunger 8 is an interference fit in a central hole in the partition 5 to seal said hole.
  • An intermediate portion 18 of the plunger is formed with a series of circumferentially-spaced longitudinal flutes 18 such that, when the base 7 is popped, the fluted portion bridges the partition 5, whereby the spaces between the flutes provide restricted communication between chambers 6 and 13.
  • Figure 5 shows a yet further plunger 8, which is suitable for a mixed drink container, in which chamber 6 contains spirits and main chamber 13 contains a mixer drink.
  • the plunger 8 has an enlarged head 19 and a reduced diameter lower end 20, the head 19 being an interference fit in a central hole in diaphragm 19 to seal the hole, and to hold the plunger 8 in position, in readiness for operation.

Abstract

On décrit diverses constructions de boîtes métalliques pour boissons, dotées d'une cloison (5) à travers laquelle est réalisé ou défini un moyen de passage par un poussoir axialement déplaçable (8). Les figures 1 et 2 montrent des boîtes dans lesquelles le poussoir (8) comporte une partie cannelée conique (12) qui se coince dans la paroi pour définir une série de passages entre les cannelures lorsque la base (7), initialement convexe vers l'extérieur, est mise dans la position concave vers l'extérieur (7'). La figure 2 montre une forme modifiable d'une base pouvant être actionnée ainsi (7). La figure (3) montre un poussoir de percement doté d'un passage axial (16) et d'un orifice transversal (17) pour fournir un passage entre les deux chambres (6, 13) de la boîte lorsque le poussoir a été enfoncé à travers la cloison (5). Les figures 4 et 5 montrent des poussoirs qui traversent en permanence ladite paroi et sont rétrécis (18, 20) pour définir un passage qui relie les chambres de la boîte lorsque le poussoir est déplacé axialement depuis une position d'étanchéité.
