Definitions

  • the invention relates to a package with a roll-up re-sealing system and a process for the production of such a package, especially flexible bags for the repeated sealing, storage and the repeated removal of liquid, dry, powdery, granular or pelletised contents.
  • seals consisting of two extruded plastic sections, one of which is formed as a groove and the one opposite as a tongue, so that they interlock with one another and can be separated again when necessary. They make it possible repeatedly to seal or open packages in the form of flexible bags. When this kind of seal is used, the problem is that the user may not notice the zipper strip when he opens the package for the first time and might perhaps damage it with a pair of scissors or even cut it off completely.
  • the patent specification U.S. Pat. No. 3,201,030 also discloses a package with a roll-up re-sealing system.
  • the proposed solution provides for the insertion of pre-stressed, resilient aids, such as wires, in the packaging material. The production and disposal of such packages has proven complicated and expensive.
  • a second variant of the solution proposed in that patent specification provides for the use of a composite material with two layers of film with different pre-tensioning, which are laminated on top of one another and are thus intended to create a roll-up effect for a package.
  • This variant of the solution involves the disadvantage that the creation of the roll-up effect takes place in an uncontrolled way and is lost again during the process of shaping, filling and sealing the package, because of the seal.
  • this kind of composite material can only be processed on a highly modified shaping, filling and sealing machine, which results in high investment costs.
  • the solution according to the invention in accordance with claim 1, therefore proposes a package characterised in that it consists completely or partially of a conditioned multilayer composite material, or that the package consists of any unspecified multi-layer composite material and that there is disposed on one package wall, beginning in the region of the opening, an adhesive label made from the conditioned multi-layer composite material.
  • the advantages of these packages consist in the fact that they can be manufactured from multi-layer composite materials of the kind conventionally used in packaging, such as standard polymers, whose composite layers are arranged by laminating or pasting one on top of the other.
  • the characteristics of the conditioned multi-layer composition cause the package to be rolled up automatically and in a controlled manner from the package opening in the direction of the bottom of the package.
  • the process of rolling up and sealing can be repeated as often as desired. It continues until it reaches the level of the contents and securely seals the package when it is not yet completely empty. In this way, the ease of handling and the service life of the package are increased, the contents can be removed in any quantities desired and at any times desired, and the quality characteristics of the contents, such as their aroma or pourability, are preserved for considerably longer than in conventional packages, since the tightness of the package is ensured. As the package always rolls up as far as the level of the contents, the amount of contents remaining is always visible at the same time.
  • An alternative version of the solution consists in the fact that the process of rolling up and sealing is transferred from an adhesive label made from conditioned multi-layer composite material to the multi-layer composite material of the package, which material may be of any other kind.
  • the conditioning process may also be carried out outside the shaping, filling and sealing machine, and the adhesive label can be applied to the package, beginning in the region of the opening, after it has been manufactured and filled.
  • the adhesive label can vary in length and width if need be, beginning at the edge of the opening.
  • the process of rolling up and sealing can of course also be transferred to the unspecified multi-layer composite material by tapes or strips of rubber or flat elastomer disposed on at least one wall of the package and applied under a tensioning force.
  • the package combined with any kind of reinforcement, such as a conventional snap closure, for catching the upper edges of the package opening, simplifies the handling of the package of the invention still further. It should also be emphasised that the package rolls up completely once it has been finally emptied, which means that it can be disposed of in a space-saving manner.
  • Another particular advantage is that the process for producing the packages according to claim 5 can be carried out on conventional shaping, filling and sealing machines. Expensive capital expenditure is not necessary.
  • the process permits the use of standard films.
  • the conditioning of the material is likewise possible with these machines.
  • the conditioning of the entire surface, or at least part of it, by means of heat-treating the packaging material can be carried out during or after the process of shaping, filling and sealing the package. This permits great technological variety in the manufacturing process.
  • the process and the package of the invention considerably increases the variety of uses to which the multi-layer film compositions can be put.
  • the roll-up and sealing process of the invention guarantees clean handling of the packages for the consumer. Ineffective makeshift solutions, such as rolling up and holding the package shut with rubber bands or the like, are no longer needed.
  • the package protects the contents for a longer time and increases the storage life of foodstuffs or luxury goods even after the package has been opened.
  • FIG. 1 shows a perspective front view of a filled package with a conditioned multi-layer composite material as a roll-up re-sealing system
  • FIG. 2 shows a perspective front view of a half-empty package made from a conditioned multi-layer composite material as a roll-up re-sealing system
  • FIG. 3 shows a perspective front view of a package made from any unspecified multilayer composite material with a shortened adhesive label made from a conditioned multi-layer composite material as a roll-up re-sealing system
  • FIG. 4 shows a perspective front view of a package made from any unspecified multilayer composite material with a longer adhesive label made from a conditioned multilayer composite material as a roll-up re-sealing system
  • FIG. 5 shows a front view of an opened package made from a conditioned multi-layer composite material as a roll-up re-sealing system combined with any reinforcement to catch the opening region
  • FIG. 6 shows a perspective front view of a package made from any unspecified multilayer composite material with tapes or strips applied under a tensioning force as a rollup re-sealing system
  • FIG. 7 shows a section through a piece cut from any unspecified multi-layer composite material
  • FIG. 8 shows a section through a piece cut from a conditioned multi-layer composite material
  • the first embodiment is shown in more detail in FIG. 1.
  • a standing bag was chosen in preference, of the kind that is used today in many fields for a variety of contents 6 , such as for foodstuffs and for animal feed.
  • the standing bag was manufactured from a conventional multi-layer composite material 3 , preferably consisting of three layers 3 ′, 3 ′′ and 3 ′′′.
  • One of the three layers, the outer layer 3 ′, for example, was placed in a state of stress during the manufacture of the multi-layer composite material 3 , which at first produces no effects in the composition.
  • a conventional shaping, filling and sealing machine was used to make the standing bag from this multi-layer composite material 3 , which had been subjected to this standard pre-treatment.
  • the standing bag is filled with the contents 6 , which could be dry feed for dogs, for example, and sealed. After sealing, the standing bag is subjected to conditioning by means of heat treatment, produced by UV radiation for instance, over its entire surface for example. It would also be possible to partially condition only one package wall 1 ′, namely the one with the outer activated layer 3 ′. Now the outer layer 3 ′, which has been activated by a state of stress, expands, and the package 1 , in this embodiment the standing bag, rolls up monoaxially from the package opening towards the bottom of the package, until it reaches a level 5 , which is the upper level of the contents 6 . The consumer opens the package 1 and removes the desired amount of contents 6 each time.
  • the package 1 preferably consists of any, preferably three-layered, multi-layer composite material 3 , the layers 3 ′, 3 ′′ or 3 ′′′ of which do not have any stress frozen in.
  • a short adhesive label 4 is applied to one of the two package walls 1 ′, beginning in the region of the opening of the package 1 .
  • the adhesive label 4 consists, for example, of a three-layer multi-layer composite material 3 , the layer 3 ′′′ has been pre-stressed during manufacture.
  • partial conditioning of the adhesive label 4 now takes place, in the form of heat treatment, so that its layer 3 ′′′, which has been activated by tension, now contracts, and the adhesive label 4 is caused to roll up monoaxially.
  • the roll-up effect is transferred by the adhesive label 4 to the package 1 .
  • the package 1 rolls up as needed only as far as the end of the adhesive label 4 .
  • FIG. 4 shows the second embodiment, with an adhesive label 4 attached over the entire package wall 1 ′, as a result of which this, too, rolls up monoaxially as far as the bottom of the package 1 , until it has been emptied completely.
  • the roll-up effect is transferred to the package by the adhesive label 4 in this example.
  • a third embodiment provides for a combination of the package 1 according to the first two embodiment versions.
  • the package 1 is provided with a reinforcement 7 at the edges of the opening region, such as in the form of a conventional snap closure or the like, for catching the upper edges of the package opening.
  • a fourth embodiment version as shown in FIG. 6, provides for the rollup re-sealing system to be transferred to the package 1 made of any multi-layer composite material 3 preferably by tapes or strips 8 of rubber or flat elastomer applied under a tensioning force at least to one package wall 1 ′ of the package 1 .
  • FIG. 7 shows a conventional multi-layer material composition 3 , which is preferably formed from three layers 3 ′, 3 ′′ and 3 ′′′ laminated or pasted on top of one another in a conventional manner.
  • the layers 3 ′ or 3 ′′ or 3 ′′′ it is sufficient for at least one of the layers 3 ′ or 3 ′′ or 3 ′′′ to consist of a polymer, varnish or foam which is provided with an internal frozen-in stress during the lamination process and which expands or contracts during a conditioning process as a result of heat treatment and thus forms a conditioned multi-layer composite material ( 2 ).
  • a multi-layer composite material 3 whose outer layer 3 ′ and inner layer 3 ′′′ have a frozen-in state of stress and whose middle layer 3 ′′ is dimensionally stable.
  • the inner layer 3 ′′′ for example, contracts
  • the outer layer 3 ′ expands
  • the middle layer 3 ′′ is rolled up monoaxially by the other two layers 3 ′ and 3 ′′′ at the same time.
  • the result is, for example, a conditioned multi-layer composite material 2 , such as is shown in more detail in FIG. 8.
  • the roll-up behaviour of the material for the packages 1 can be controlled such that different roll-up diameters and roll-up thicknesses can be achieved.
  • additional layers of conditionable material can be integrated into the multi-layer composite material 3 , which assist in regulating the build-up of tension within the composition.
