  • US patent 5,833,368 discloses a beverage container which is made by film material.
  • the container comprises a discharge system which involves a pull tab system covering a straw input area.
  • the invention relates to a disposable can formed at least partly by a flexible film material wherein
  • said can comprises a top surface and wherein said can has at least one discharge arrangement comprising at least one re-closure foundation and wherein said discharge arrangement is attached to the can.
  • a drinking can may advantageously be formed by film material.
  • the can may advantageously be suitable for use in the same way as conventional cans made of solid walls and at the same time be manufactured in a very cost-efficient way.
  • the can may be disposed in a very environmentally friendly way.
  • the can according to the invention may be easily collapsed and handled after use during disposal.
  • the can should facilitate transportation, storage of carbonated or non-carbonated beverages and facilitate drinking by means of a discharge arrangement of the can.
  • the drinking should be facilitated directly without a requirement for additional accessories such as straws and mouthpieces.
  • the invention addresses basic application of cans from a user perspective, as conventional advantages and comfort are obtained by the flexible can together with further advantages such as comfortable and easy collapsing of the can after use which may easily be obtained just by squeezing the can by means of the hands instead of relying on compression tools.
  • the flexible can provides further significant advantages with respect to the possibility of incorporating e.g. filter or further internal barriers within the can in a cost-effective way as many such measures may be obtained by altering the sealing pattern or procedure and/or simply applying a relatively cheep further film.
  • the flexible can according to the invention offers several various wall materials which may be adapted to the specific application, i.e. with or without UV barrier, with or without heat insolating properties, with or without transparency, etc.
  • a disposable can formed at least partly by a flexible film material comprises a discharge arrangement which may be resealed one or several times by means of a re-closure foundation.

  • the further sealing functions as an initial sealing of the re-closure foundation, thereby facilitating that the can may be initially provided completely sealed to a user even without necessarily mounting the re-closure initially. If, on the other, the re-closure has been mounted initially, the further sealing ensures that the risk of re-closure leaking is minimized.
  • the can has a main volume 331.

  • the barrier arrangement 410 comprising a sheet 450 perforated by perforations 420 is fastened to the can and divides the internal volume 431 in two volumes, the main volume 431 and an outlet volume 425.
  • the barrier 410 may serve several different purposes.
  • One purpose is to restrict or counteract sudden flow from the internal volume 431 to the exterior via an opening 480 in the re-closure foundation 44.
  • Another purpose may also be to act as a filter to residues which should not be outlet during emptying of the can.
  • residues may e.g. comprise food-fibers, small fruit parts, etc.
  • the above-illustrated embodiment basically is most suitable for liquid unless the barrier arrangement is carefully designed to allow passage of the content of the main volume 431 from the interior through the barrier and an opening in the re-closure foundation.
  • Another important purpose of the barrier may also be to add form stability to the flexible can.

  • Such top surface may thus e.g. be top surface 26 of the can 20, or top surface 46 of the can 40.
  • such underlying flexible film may comprise part of another wall of a film based can as illustrated in the can 30 of fig. 3a-c and thereby form a further sealing 5801.

  • the re-closure foundation may be cast or molded in a suitable material according to any suitable shaping technique and any suitable material. It is however noted that both the re-closure 505 and the re-closure foundation 54 may preferably be made in a material which is compatible with the can or at least most of the can. Such considerations may both relate to environmental issues such as disposal and incineration and moreover with respect to mutual attachment. Thus, when applying compatible materials at least in the border zone between the illustrated underlying surface and the contact part of the re-closure foundation 54, the two portions may be mutually heat-welded or glued.
  • the top surface should be at least partly covered by a further sealing in order to protect the part of the can applied during drinking hygienically prior to the initial opening of the can.
  • the further sealing may e.g. comprise a sheet covering the opening and e.g. a part of the edge of the can.
  • the further sealing should form a sealing, which per se, provide a proper and sufficient sealing of the can.
  • perforations facilitating removal of the further sealing 5801 should preferably be avoided to ensure that the can is completely sealed prior to user. Further this could have the benefit of contributing to the keeping of the quality of the content of the can.
  • the further sealing may however be associated with weakening lines or other suitable "break-helping" measures.
  • the lid 505 has been rotated about 10-40 degrees and the further sealing 5801 has been broken as this sealing is completely attached, e.g. by heat-welding or gluing, to the bottom of the lid 505.
  • the lid 505 has now been rotated and a part of the lid is not longer mechanically engagement with the flange 541.
  • the lid 505 has been turned about 90 degrees and is now free of engagement with the re-closure foundation and the lid may be removed. It is noted that the further sealing 5801 is attached to the bottom of the lid and is removed together with the lid 505 thereby establishing a discharge arrangement formed at least partly by an opening 580 formed in the ring-formed re-closure foundation 54. This opening may be re-closed by means of the lid 505 by means of rotation.
  • the locking of the lid may be obtained in several different ways.
  • a click lock may be applied or a slight inclination may be established between the flange 541 and the corresponding flange of the lid in order to establish a squeeze or pinch- lock.
