Definitions

  • the invention is based upon the idea that the type of package which has already been developed and won acknowledgement when used for powderformed products which should be packed airtightly and in many a case even vacuumtightly, could be especially suitable for satisfying the said demand.
  • the difficulty thereby, rather has been in the provision of an opening arrangement for the package, which is easy to manipulate, which will not splash, which will not be damaged during transport, and which makes it possible to pour off the liquid stored in the package to its full extent.
  • the present invention is based upon a package of the type rectangular in cross section, which is provided with a stiffening part of cardboard orsimilar material and a tightening part in the form of a liner of plastic, eventually metallized plastic, whereby said liner is tubeformed and extends so much above the sides of the outer package, that it may be closed by even closing in a satisfactory way, and the outer package is provided at each end with closing flaps, which are bent down along so situated lines that they form together a flat closed surface, extending practically completely perpendicularly to the side surfaces of the package.
  • the present invention refers to an arrangement in packages for liquids of the kind, containing an outer package of cardboard or similar material, and an inner layer laminated thereto, or a free liner of an airtight material such as plastic or the like, said package being provided with four sides separated from each other by creasing lines, and at each end of each side a closing flap, arranged to be folded down onto the package after closing the liner.
  • a pour off arrangement is provided in one of the closing flaps, which, when closing the package, is situated most inwardly, and this pour off opening is so arranged, that it may be torn up by a light grip.
  • a hole for forming the tap off opening is cut through the closing flap of the outer package as well as through the plastic laminate layer of plastic liner belonging thereto, and this hole is inwardly as well as outwardly covered by a plastics layer, the inner plastic layer being attached by plastic welding or in similar way to the innerside of the package and within a limited part of the hole welded to the outer plastic layer, and the outer plastic layer being formed to agrip tongue for tearing up the welded together part of the two :plastic layers.
  • the hole is drop shaped with the pointed end turned onto the upper edge of the closing flap, and with the rounded end of a lapping creasing line, by means of which the closing flap is connected to the side pertaining thereto.
  • FIG. 1 shows the blank for a package of the kind here concerned, developed in the level
  • F lGS. 2 and 3 show on an enlarged scale a section through the opening, first in FIG. 2 before it has been torn through, and secondly in H6. 3 after it has been torn through.
  • FIG. 4 shows a modification of the blank of FIG. 1.
  • the package thus, in first place comprises a stiffening part which may be made from cardboard, and :a tightening part, which is preferably made from plastic.
  • the stiffening part is cut in the form, shown by lines drawn in full in FIG. 1, and is provided with creasing lines .according to the dotted lines in FIG. 1.
  • the side 13, situated in the drawing most at right is provided with a pasting flap22 intended to be fasted to the inner side of the side piece 10 when the-package is made up in a tube form squared in cross section.
  • the liner 23, which is already tube formed in advance, is attached to the package, so that it will cover the inner sides-of the four side pieces, when the package has been made up into tube form, squared in cross section.
  • the four closing flaps in the bottom are closed in the traditional way, which means that one will first turn the flaps 14 and 16 inwardly, so that their edges meet each other, and thereafter the two remaining flaps l5 and 1'7, one before the other one, whereby the different flapsareattachedtoeach other by pasting.
  • the extending part of the liner Beforefoldingin the flaps,of.course, the extending part of the liner has in the traditional way been plained into a so-called plain, closing, which has .been'welded together.
  • the triangular ears thereby created are automatically folded in at the closing of .the outer package. This closing procedure, of course,is known per se.
  • a hole has been cut, going through the cardboard material as well as through the liner, and this was made already at the production of the package blank and the liner or at their combination with each other.
  • This hole has been shown in the drawing to be drop formed, which is very advantageous form of the hole, but one may, of course, also use other forms; for instance the hole may be made rhombic with the greater diagonal turned in the vertical direction or the like.
  • the edges of the hole are shown in FIGS. 1, 2 and 3 at 24.
  • a piece of plastic 25 is welded along the edges of the hole 24, and on the outer side of the package a second piece of plastic 26 is welded to the edges of the hole.
  • the two pieces of the plastic further are pressed onto each other and welded to each other within a surface, which has been marked in FIG. I by the line 27.
  • This kind of a sealing which may be opened, is previously known although it has not earlier been used in connection with the kind of package here concerned, nor has it been placed in a place of the package where it should be placed according to the present invention.
  • the intention with the earlier known closings of this kind, as a matter of fact, has been that one should stitch them through by some pointed object.
  • a surface inside of the line 27 but preferably also the surface inside of the line 24 and most preferably all of the surface about the outer plastics piece 26 should be available from outside. For this reason steps have been formed in the two closing flaps 19 and 21. The steps are so placed, that they leave the surface of the plastic piece 26 uncovered at the closing of the package, whereas the extending tongue 28 and 29 give completely sufficient attachment for pasting the package tight.
  • the part of the plastic layers representing the welding range shall be torn away by means of the outer plastic layer.
  • the inner plastic layer certainly is well attached to the liner, but if the outer plastic layer is rather loosely attached to the side of the cardboard, for instance by means of some weak gluing or the like. It is even possible, considering the greater thickness of the outer plastic layer, as compared with the thickness of the inner plastic layer, to leave the outer plastic layer completely without any connection with the outer side of the cardboard.
  • the tearing tongue 30 is compulsorily turned down along the side 12 and attached thereto by means of glue, paste, a lacquer or some other only weakly attaching medium within a point 31. It has now proved, that depending on how quickly one releases the tearing off tongue 30 from the side 12, it may certainly happen, that the release take place not only at the point 31, but rather often, instead, the cardboard material splits itself up, and its surface layer will follow with the tearing offtongue. In order that such a splitting phenomenon shall not take place at an early state, so that the splitting shall not extend to the opening 24 or 27, a cutting through 32 is arranged in the cardboard material. This may go completely through the cardboard, but it is more suitable, that it only runs for instance half way through the material of the cardboard.
  • the placing of the opening 24 is that it should be situated in a place of the package, where the liner is single, that means not double folded or plurality folded.
  • the plain closing ridge should run from the middle of the side 11 to the middle of the side 13 and be folded down in a direction onto the closing flap 18. If the package is square formed in cross section as shown in the form of execution, thereby, after the two plain closing ears have been folded inwardly, two diagonal limination lines are formed, limiting four fields, each of which being situated opposite to one of the closing flaps.
  • the liner is threefold and within the field, opposite to the closing flap 18, the liner is certainly single, but it is in part covered by the plain closing ridge. Only within the field opposite to the closing flap 20, the liner is single, and therefore the opening 24 has also been provided within this field.
  • FIG. 4 shows the same blank for a package, as also shown in FIG. 1, modified in accordance with the above.
  • the two closing flaps l9 and 21 are principally square-formed, and that the step is replaced by a perforation line 35 or 36, respectively, so that the pieces 33 and 34, respectively, of these two closing flaps can easily be torn away along the perforation lines. They will therefore, as long as the package is tight and nontouched, cover the opening inside of the two lines 24 and 27 and protect the plastic from damage, but they can easily be torn away, and thereafter the package will have identically the form, which will be the consequence of the use of a blank according to FIG. 1.
  • the remaining parts of the two closing flaps 19 and 21 should be pasted to the flaps below them, but the parts 33 and 34 of these two closing flaps should be without any glue or paste.
  • the closing flaps 19 and 21 are so high, that they practically completely extend to the creasing line of the other one of said flaps. In such a case, of course, one should only provide perforations and a possibility of tearing away a part for providing a step in the one closing flap, but the other closing flap should already from the beginning have part of it cut away for providing the step.
  • the drop form of the opening inside of the line 24 is very advantageous. It makes it possible to get a strong, wellrounded pouring squirt from the lower, broader part of the opening, whereas air may without any difficulty enter through the upper, pointed part of the opening.
  • the upper end of the opening further should also be pointed for the reason, that thereby a natural end for the tearing off is obtained so that there will be no tendency for the tearing to continue outside of the line 27.
  • An arrangement in packages for liquid of the type containing an outer package of cardboard and an inner airtight plastic liner said package being provided with four sides separated from each other by creasing lines, and at each end of each side a closing flap arranged to be folded down flat onto the package after the closing of the liner to form two flat ends of the package a pour opening in one of said flat closing flaps which, when the package ends are closed, is situated innermost, the closing flaps situated outside of the said one flap being of such a form that the pour opening will be accessible, said pour opening comprising a hole cut through the said one closing flap as well as through the plastic liner adjacent thereto, said hole on its inside as well as on its outside being covered by a layer of plastic, the inner plastic layer being attached to the inner side of the package and also within a limited part of the hole being attached to the outer plastic layer, and the outer plastic layer being formed to include a gripping tongue for tearing away the parts of the two plastic layers which are attached to each other within the said openmg.
