Definitions

  • the present invention relates to a distribution unit comprising a plurality of liquid packages for pressurized contents.
  • Glass has good properties permitting a gas-tight package which withstands the inner pressure the contents exercise on the package and which does not affect the taste of the liquid contents.
  • Glass bottles can be cleaned and refilled or crushed when the raw material is to be used anew for bottle manufacture. To wash and refill may be considered advantageous but the washing process entails undesirable expense and an appreciable consumption of energy.
  • Conventional glass bottles moreover, are heavy and require a large volume in transport. The weight makes them also less attractive for the consumer.
  • aluminium cans discussed in recent times, are also eminently suitable for recycling.
  • the main disadvantage of aluminium as packing material is the expensive and energy-demanding manufacture of aluminium, which also tends to become more expensive still with rising energy prices.
  • a further disadvantage of this type of packages is that their inside is varnished and that this varnish contains solvents which negatively affect the taste of the liquid.
  • empty packages which are transported to the brewery cannot be stacked into one another, so that the transport becomes inefficient and expensive.
  • Plastic bottles which are also encountered on the market for carbonated beverages are expensive.
  • the plastic raw material may be reused, however, for another manufacture, such as e.g. insulating padding in clothing.
  • the packaging should be inexpensive and the manufacture should not be too energy-demanding or require an expensive raw material.
  • the package should be recoverable. Moreover, it should be light from a point of view of the consumer and of transport and, in particular, it should be stackable for a more efficient transport in empty state.
  • the packing material should protect the product and it should not affect its taste and quality. The material also should be gas-tight and withstand the internal pressure which the liquid exercises on the package.
  • US-A-4 049 122 describes a distribution unit in accordance with the preamble of claim 1 whereby each package is provided at its top surface having the larger radius with a fully removable tear-off closure which is received and sealably held by an upper beaded rim.
  • Each package is further provided with a ledge means that extends from its side wall in a predetermined spaced relation with one of the top and bottom ends of the package to thereby allow a handling of a plurality of used, empty packages in the form of palletizing columns of stacked, nested packages in a non-locking relationship as secured by such ledge means serving accordingly to space apart the side walls of the packages as successively arranged in such palletizing columns.
  • An object of the present invention is to provide an improved distribution unit for liquid packages of the kind referred which contributes to a better utilization of volume primarily of the filled packages.
  • a further object of this invention is to provide a distribution unit using liquid packages possessing the properties mentioned above and made of a material which contributes to the retention of the quality and the taste of the liquid contents.
  • the package 1 is in the shape of a truncated cone, with a shell surface 2 manufactured from a thin metal foil,e.g. thin sheet steel, laminated at least on one side with a thermoplastic material.
  • the metal foil has good gas-tightness properties.
  • the thermoplastic material is chosen so that it has good welding characteristics. Moreover, it should have good adhesion capacity to metal and it should be ecologically beneficial. If a choice is made to manufacture the shell surface 2 of thin sheet steel, it is possible already from the start to make use in the manufacture of recycled scrap and thus make the manufacture less expensive. The sheet steel too may possibly be recovered.
  • the stamped out sheet is rolled round to a cone and the thermoplastic material on its surface is welded with overlap to a longitudinal joint 3.
  • the joint 3 coincides with a generatrix on the truncated cone.
  • the package 1 is provided with bottom 4 and top 5.
  • the bottom 4 should be designed so that it can withstand the pressure from the enclosed liquid. If it is chosen to make the bottom 4 of sheet metal it should be covered at least on one side by means of lamination with, or application of, a thermoplastic material and be welded together with the thermoplastic layer of the shell surface 2 by heating.
  • an opening device 6 is fitted in a tight manner which on opening of the package 1 is intended to be torn off so that the enclosed liquid becomes accessible for consumption.
  • the bottom radius is chosen so that it fits the module used in the handling of distribution and transport.
  • the height of the package, and with it also the cone angle, is determined by the volume, bearing in mind the product volume, head space, that is to say splash space, and bottom and top design. The height, and the cone angle connected therewith, are limited by practical considerations in respect of the ease of handling and the desire that the packages should make the best possible use of the distribution units.
  • the enclosed volume is calculated by the formula ⁇ H 3 R2 (3 - ⁇ 2) where H represents the height and R the radius of the bottom area 8.
  • Fig.3 shows a distribution unit 9 comprising 13 off packages 1,10. With different package dimensions, of course, a great number of other packing patterns may exist taking into consideration the transport and distribution modules.
  • Fig.3 demonstrates also that if a package 10 with an aforementioned relationship between the radii of top and bottom surfaces is positioned upside down, that is to say reversed between 4 adjoining packages 1 positioned the right way up, the reversed package 10 will rest on its top surface 7, that is to say wholly on a level with the bottom surfaces 8 of the four packages 1 which are positioned the right way up. At the same time a tangential touch is obtained along four whole generatrices on the shell surface 2 of the reversed package 10 and one whole generatrix on each shell surface 2 of the four packages 1 which are positioned the right way up. Thus a good utilization is obtained of the space which the packages 1 occupy in their distribution unit 9.
  • the packing pattern is held together e.g.
  • the units 9 can also be stacked in vertical direction, since their surfaces are wholly plane and the internal pressure of the packages 1 imparts to them great strength and endurance against the effect of external pressure.
  • a distribution unit comprising liquid packages which complies with the demands regarding gas tightness and strength for carbonated beverages which is space serving and which is cheaper than those for pressurized contents on the market at present.
  • the used liquid packages are ecologically more beneficial, since they can be manufactured mainly from recycled material which can be recovered again.
  • the manufacture moreover, is not as energy-demanding as e.g. that of aluminium cans.
  • distribution unit is obtained which in an improved manner preserves the quality and taste of the enclosed beverage, as the enclosed beverage is in contact with a thermoplastic material and as it is protected against light by the metal foil.
