Definitions

  • the present invention refers to an opening device for a package of the kind whichconsists of a tube which is closed at its ends by transverse seals and has had imparted to it a preferably parallelepipedic f-orm with doublewalled, triangular flaps projecting from the ends of the package, said aps being folded in against the end and/or side walls of the package andone of them being intended to be folded out and to form part of the opening device.
  • Square packages of the abovementioned kind are used both for pulverized and granular products and for liquids, eg. milk.
  • the invention is intended to provide an opening device which may easily be opened by the consumer, this new opening devi-ce being principally characterized by the fact that the triangular flap which is to
  • FIGS. 1 and 2 show two side views of la rst embodiment at right angles to each other
  • FIG. 3 shows part of FIG. 2 at an enlarged scale
  • FIG. 4 shows a View corresponding t-o that in FIG. 2 but with the package partly opened
  • FIG. 5 also shows a view corresponding to FIG. 2 but with the package completely opened
  • FIG. 6 and 7 show two side views of a second embodiment of the invention at right angles to each other
  • FIG. 8 shows part of FIG. 7 at an enlarged scale
  • FIG. 9 shows the package according to FIGS. 6-8 as seen from the top
  • FIG. 10 shows a view corresponding to FIG. 7 but with the package partly opened
  • FIG. 11 also shows a view corresponding to FIG. 7 but with the package completely opened
  • FIG. 12 shows a perspective view of a third embodiment of the invention.
  • FIG. 13 finally shows a perspective view of a fourth embodiment of the invention.
  • the package 1 shown in FIGS. 1-5 may for example be manufactured by forming -a web-shaped starting material into a tube and transversely sealing it within narrow, parallel zones, the filling of a package taking place between two successive transverse sealing operations.
  • the parallelepipedic form may be given to the individual packages before or after they have been detached by cuts in the sealing zones, this forming operation preferably taking place in a parallelepipedic form under a certain longitudinal upsetting action.
  • the package 1 gets side walls 2 and 3 and end walls 4.
  • the end walls 4 are traversed by fins 5 which have been formed at the transverse sealing and which, as will appear from the figures, have been folded down -against the end Walls 4.
  • the fins 5 further continue out on four triangular, doublewalled flaps 6 which have been produced at the forming operation and only one of which is shown in FIG. 1.
  • the flap 6 shown is attached to the side wall 3 to be relatively easily releasable therefrom, as Will be described more closely below.
  • This flap 6 is further provided with a weakening line 7, which extends transversely across the two layers of the double-walled flap and makes it possible to tear off the outermost part ⁇ thereof to open the package and at the same time produce la pouring spout.
  • the weakening line 7 consists prefera'bly of a perforation partly penetrating the packaging material.
  • a strip 8 for example Wear-resistant paper i.e. to the bottom side and at least partly to the top side of the flap.
  • the strip 8 is doubled and extends downwards so far that it projects below the flap 6.
  • the flap 6 is held in a folded-down position by the part of the strip 8 provided on its bottom side being glued on or attached in any other suitable way to the extension of it which is situated on the package side 3 and which in turn is attached to the package wall itself.
  • a second strip 9 serving as a gripping flap is provided at .
  • the package shown in FIGS. 6-11 differs from that shown differs from that shown in FIGS. 1-5 only by the tear-open indication 7 being replaced by an emptying hole 10 on the inside of the flap 6 and a vent hole 11 on the t-op side 4 of the package, the strips 8 and 9 'being at the same time modified for adaptation to these holes and therefore given new reference numerals, namely 12 and 13, respectively.
  • the strip 12 is arranged to extend across the end wall 4 so as to cover the hole 11 therein. At the same time this strip naturally covers the hole 10 in the same way as the strip 8 in the embodiment according to FIGS. 1-5 covered the tear-open indication 7. Moreover, the same reference numerals have been used in FIGS. 1-5.
  • the embodiment according to FIG. 12 differs from that shown in FIGS. 6-11 only by the strips 12 and 13 being replaced by a single strip 14, the loose end 15 of which has the same function as the strip or gripping flap 13.
  • the left hand part of the strip 14, as seen in the figure, is fixed in the same way as for example a double-sided tape both to the side wall 3 and to the inner side of the fla-p 6, Where it simultaneously closes the emptying hole 10.
  • it closes the vent hole 11 by being fixed at its right hand part, as seen in the figure, to the end wall 4.
  • the strip 14 is free from the package so that its end part 15 may be easily seized, when the package is to be opened.
  • the embodiment according to FIG. 13 differs from that shown in FIG. 12 only by the shape of the opening provided in the flap 6, and here designated by 10a.
  • the opening has been given the form of a V-shaped slot in the web form of the material, the apex of which is situated on the inside of the foldeddown flap 6.
  • the strip 14 is intended to have substantially the same extension as in the embodiment according to FIG. 12, apart from the fact that its left hand end has to be folded up on to the outside of the flap'6 so as completely to cover the slot 10a.
  • the tip of the flap 6 shown in FIG. 13 is not intended to be completely removed.
  • FIGS. 3 and 8 the flap 6 is shown, for the sake of distinctness, at a certain distance from the package itself. In practice, however, as above mentioned, it is xed in close engagement with the package side.
  • An opening device for a package of the kind which consists of a tube which has been closed at its ends by transverse seals and given a parallelepipedic form, a double walled triangular Hap extending from the edge of said package formed by the juncture of a side wall with an end wall thereof and communicating with the interior thereof, an opening in the inner wall of said ap which is ⁇ adjacent to said side wall when said flap is folded downwardly and a strip xed to said inner wall of said ap and covering said opening, said strip extending from the free corner of the flap inwardly to said edge and downwardly along said side wall beyond said free corner of said flap.
