- Another important purpose may also be to add form stability to the flexible can.
- Evidently, several other barrier arrangements may be made within the scope and the spirit of the invention.
- It is moreover noted that the
can 50 has some further modifications when compared to thecan 20 with respect to the pull tab design and the design of adrinking edge 52. - Starting with the drinking edge design, a
reinforcement 590, e.g. in the form of a relativelyrigid string 590, has been inserted into a folded side wall 530 forming thedrinking edge 52 and part of apull tab 51. Thereinforcement 590 may be made of any suitable material, preferably a polymer, and be both welded or glued within the compartment forming the inside of the drinking edge or even just be positioned by means of the compartment-defining sealing. The function of the appliedreinforcement 590 is to keep thedrinking edge 52 form stable and comfortable to drink of during discharge. Finally, thereinforcement 590 may simply be fixated at the two ends within the fold byside weldings - Turning now to the modified
pull tab 51, this tab is formed by peel-lines overlay sheet 5001 which covers atop surface 56 of thecan 50 at least partly and at least enough to cover acut 581 in thetop surface 56 forming a horse shoe formed opening 580 in thetop surface 56. The peel-lines overlay sheet 5001. It is noted that the perforated line or cut form a flap-like arrangement pointing towards the circumference of the top surface, thereby providing a self-opening arrangement, which when inclined slightly, will facility relatively unrestricted output of liquid. Moreover, it is noted that the opposite end of the flap pointing towards the circumference should be as close to the circumference as possible in order to facilitate complete emptying of the internal volume. Again, theoverlay sheet 5001 may form a single sheet welded to a side wall 530 or simply be formed by a folded prolonged side wall 530 as illustrated. - The
overlay sheet 5001 is welded to thetop surface 56 by a peelable sealing over the entire area of the overlay sheet, although it is preferred that the end of theoverlay sheet 5001 or at least the part of the overlay sheet forming thepull tab 51 defined by the peel-lines top surface 56 thereby enabling a user to grip thepull tab 51. - It is noted that the
opening 580 is now defined by a flap which is still fastened to thetop surface 51 although discharge is now made possible. -

FIGS. 7A and 7B illustrate a further embodiment of a flexible can 70 supported by anouter support 701 according to the invention. The can 70 corresponds largely to thecan 20 illustrated inFIG. 2A but now without a prolonged drinking edge. - The can 70 may be positioned within the cylindrically shaped
outer support 701, supported at the bottom by abottom support 703 and protected at the top by atop support 702. The bottom support is moreover formed in asuitable form 753 to mechanically fixate theouter support 701. - All
support components - The can may moreover be fastened, e.g. by gluing or welding to the outer support or simply just be mechanically fixated by the
outer support arrangement - When applying the flexible can for carbonated drinks, all surfaces of the can should be supported by the outer support, i.e.
outer support 701,bottom support 703 as well as thetop support 702 in order to compensate the significant pressure in the can. -
FIGS. 8A and 8B illustrate a further embodiment of the invention where acan 80 is positioned in anouter cardboard support 801. Thecan 80 corresponds largely to thecan 10 illustrated inFIG. 1A but now without a prolonged drinking edge. - The
outer support 801 comprises a peel-off strip 808 integrated into the outer support and with ahandle 807. -
FIG. 8B illustrates when the peel-off strip has been removed and the outer support has been split into twoseparate parts can 80. - In the illustrated embodiment, a further embodiment will now be described. This embodiment involves that the
can 80 is brought to the consumer within theouter support - The user breaks the sealing 808 as explained above and removes the
can 80 from theouter support 801. Then, the user opens the discharge arrangement and pours liquid contained within thecan 80 into the belowouter support 801 and finally drinks the liquid from the belowouter support 801 as a cup. -
FIG. 9A toFIG. 9H illustrates a number of alternative embodiments of the application of outer support arrangements for use with a can, e.g. thecan 10. - The outer support arrangements comprises an
outer support top support bottom support - When applying the can and the outer support arrangement for carbonated liquid the outer support has a very important function of counteracting the pressure within the can, i.e. ensuring the film structure does not break due to the relatively high pressure invoked by the carbonated liquid. Thus, the use of a combined flexible can and an outer support solves a problem in relation to keeping carbonated liquid in flexible container which has never been solved before.
- The outer support may advantageously be formed in relatively rigid and form-stable polymer of cardboard-based structure.
- The can may fit loosely into the outer support or be fastened to the outer support.
