Definitions

  • the present invention relates to a beverage dispenser capable of releasing gas in solution at atmospheric pressure, comprising a container of which at least a portion of the wall is deformable as and when dispensing said beverage, this container being disposed in an enclosure the wall of which is dimensioned to resist the pressure prevailing in this container following the release of said gas and comprising means for preventing an increase in the volume of said container following the distribution of said drink, under the effect of the pressure increase.
  • these packages can only be used if the flexible container is housed in a rigid enclosure and means allow the wall of the flexible container to be retained at a volume corresponding constantly to that of the liquid. to prevent degassing of the drink.
  • an elastic element is not appropriate since the force to be exerted on the walls of the flexible container varies considerably depending on whether or not the carbonated drink which it contains is withdrawn.
  • the pres Zion gradually decreases, so that the force to be exerted on the walls of the flexible container to reduce the volume left free by the volume of beverage withdrawn is low and decreases to become zero or negative depending on the volume withdrawn.
  • the container is hermetically closed, the liquid degassed until the pressure reaches about 1.1 ⁇ 105 to 3.105 Pa. If an elastic element is used, this will flex until an equilibrium s establish so that some increase in the volume of the container occurs with a corresponding loss of the volume of gas.
  • the spring pressure decreases. With a spring element, the pressure of the spring is added to that of the liquid, so that when the container is full, this pressure can be excessively high.
  • the object of the present invention is a solution which has the advantages associated with filling the volume released during drawing off with an incompressible fluid, but without having the disadvantages.
  • the present invention relates to a beverage dispensing container according to claim 1.
  • the advantage of the proposed solution lies in the fact that it is simple and that the container according to the invention is entirely autonomous, that is to say that it can be used anywhere, which allows its use in all circumstances.
  • the container according to the invention makes it possible to reduce the weight of the packaging, its volume as well as its price, while retaining the carbonated properties of the drink.
  • this solution therefore has exactly the same advantages as that using an incompressible fluid to fill the space between the flexible container and the rigid enclosure.
  • Fig. 1 is a cutaway perspective view of this embodiment.
  • Fig. 2 is an elevational view in section of the variant of FIG. 1.
  • Fig. 3 is a sectional view along line III-III of FIG. 2.
  • the container itself is constituted by a flexible bag 1 formed of two polyethylene sheets covered with aluminum to make them gas tight, welded to each other at their periphery and dimensioned to provide a given volume between them after deformation. .
  • This flexible bag 1 has an opening (not shown) for receiving a dispensing valve 2.
  • An enclosure 3, in this example of cylindrical shape, with a relatively rigid wall, serves to protect the flexible bag 1 from external aggressions and to allow the carbonated drink to be kept under a sufficient pressure to prevent its degassing.
  • the wall of this enclosure can be made of cardboard, the parts, forming its bottom and its cover, being able to be reinforced or made of metal and crimped onto the side wall of cardboard.
  • the enclosure-3 contains a latching mechanism which comprises a tubular element 4 of injected plastic, the wall of which surrounds the flexible bag provides three longitudinal grooves 5, the bottom of which has a ratchet toothing 6.
  • This tubular element 4 fits into the enclosure 3 and its base rests on a disc 7 whose diameter is equal to the inside diameter of the enclosure 3, so that this disc 7 overflows with the element tu bulaire 4.
  • the edge of this disc has four notches 8 spaced at 90 ° from each other and whose respective bottoms are on a circle whose diameter is smaller than that of the tubular element 4.
  • Another disc 9 of smaller diameter than the inside diameter of the tubular element 4 is disposed on the flexible bag 1 and closes the upper end of the tubular element 4. It serves to limit the volume of the flexible bag 1. A this effect, this disc 9 has three elastic tabs 10 at its periphery each provided with a ratchet tooth 11. When the disc is placed at the upper end of the tubular element 4 with the pawls facing the longitudinal grooves 5, these pawls 11 engage in the respective ratchet teeth 6.
  • Two elastic elements 12, in the form of rubber bands, intersect under the lower disc 7, are positioned in the notches 8, rise between the flexible bag 1 and the inner wall of the tubular element 4 and come to hang at tenons 13 molded to the upper surface of the disc 9, thus exerting a tensile force which tends to cause the disc to descend along the internal wall of the tubular element 4, the latter being prevented from going up thanks to the pawls 11 in engagement with ratchet teeth 6.
  • the first consists in introducing the upper disc 9 into the tubular element 4 before filling the flexible bag 1.
  • This mounting method requires releasing the pawls 11 from the ratchet teeth 6 while the drink is introduced into the container.
  • a pin with three branches which would allow the three pawls 11 to be released simultaneously.
  • Another solution would be to introduce the flexible bag 1 filled with drink into the tubular element 4 or to fill it in place before putting the disc 9.
  • the disc 9 is then introduced and it is lowered into the tubular element 4 until '' it comes into abutment against the flexible bag 1 filled with li which has taken substantially the shape of a cylinder.
  • the ends of the two elastic elements 12 are then passed through the slots 14 to which they were temporarily attached to the studs 13 of the disc 9.
  • the enclosure 3 is closed at its upper end, for example by a crimped cover 15.
  • the gas dissolved in the drink is released until the pressure in the bag 1 equilibrates with the partial pressure of C0 2 in the liquid.
  • This pressure is dependent on the CO 2 concentration and the temperature of the drink. It is generally between 1.105 and 3.105 Pa for carbonated drinks.
  • the reduction in volume causes a reduction in pressure, since the dissolved gas does not release instantly, so that very little force is enough to lower the disc 9.
  • C is the reason why simple rubber bands are sufficient.
  • the pressure gradually rises in the bag 1, but at this time, only the disc 9 and the ratchet teeth 6 oppose the swelling of the bag, the elastic elements 12 then playing no role.
  • Figures 2 and 3 illustrate a variant which has certain advantages compared to the embodiment of Figure 1.
  • the other branch of this blocking member 20 passes through an opening 21b of the cylindrical rim 2la and has an opening 20b in which the rod 16 passes freely when the branch in which this opening 20b is formed is oriented perpendicular to the longitudinal axis of the rod 16, but which hangs on this rod when this branch is inclined relative to this axis.
  • a spring 22 is compressed between a bottom 23 secured to the tubular element 18 and the piston 21.
  • the spring 22 pushes the piston 21 which slides along the internal wall of the tubular element 18 and drives the locking members 20 by the upper edge of its opening 21b.
  • the pressure inside the flexible bag 19 increases under the effect of degassing.
  • the bag then pushes against the piston 21 to make it go up.
  • the blocking members 20 which press on the piston 21 tilt since the pressure is exerted on one of their ends opposite to that which is crossed by the opening 20b.
  • the edges of this opening are then blocked on the rod 16 and these blocking members 20 then prevent the piston 21 from continuing to rise.
  • the cylindrical rim 2la for guiding the piston 21 also serves as a stop against the bottom 23, so that when the flexible bag is filled, the pressure is not supported by the locking members 20 but by the bottom 23 against which the cylindrical rim 21a abuts.
  • the rods 16 may preferably have a rectangular section with rounded corners, the long axis of this rectangular section being arranged radially in relation port to the axis of the tubular element 18, to increase the resistance of the rods vis-à-vis the pressure exerted by the flexible bag 19.
  • the opposite faces of the rod 16 forming the short sides of the rectangle can be roughened by transverse knurled streaks.
  • FIGS. 1 to 3 show elastic elements 12 or a spring 22 for lowering the disc 9 respectively the piston 21, these elements only constitute means which make it possible to make this disc 9 or this piston 21 integral with the flexible bag 1 respectively 19. It is possible to envisage making these elements 9 and 21 integral with these flexible bags 1, 19 by means other than elastic elements. This is how we can consider gluing or welding this disc 9 or this piston 21 to the flexible bag 1 respectively 19. Since the bag is only filled with an incompressible fluid (liquid without gas volume) when the liquid is drawn off, the pressure inside the bag drops rapidly to atmospheric pressure and because the volume of liquid dispensed is not replaced by gas, the volume of the bag undergoes a reduction in volume corresponding to that of liquid racked. Therefore, if the disc 9 or the piston 21 is integral with the wall of this bag, it is driven by it following the decrease in the volume of liquid inside this bag.
  • incompressible fluid liquid without gas volume
