Definitions

  • the invention relates to a film bag, in particular for beverages, consisting of at least one film section, which with at least one Longitudinal sealing seam, at least one transverse sealing seam and one head sealing seam encloses an interior space limited on all sides, with at least one in the a film section a substantially parallel to the head seal seam Line of weakness is provided.
  • Bags made from film webs come in many different designs known. Liquids, especially drinks, can also be in them granular or powdery materials packed and kept ready for consumption become. Either one is used to produce such foil bags single foil web folded over and by means of a longitudinal sealing seam into one Hose connected, or two layers of foil placed on top of each other two longitudinal sealing seams connected to a tube. With cross seal seams, One of which is usually only attached after filling, is formed the individual bags, simultaneously with the attachment of the last cross seal the bag can also be disconnected from the hose. At the bottom The end of the bag can be a bottom formed by an inserted piece of film be present, which enables the bag to be placed on a horizontal surface to stand upright.
  • the invention lies Based on the task of proposing a foil bag in which the risk of Leaks due to weakening of the longitudinal sealing seam due to a tear notch does not exist and which is still very easy to tear open.
  • this bag When this bag is torn, it runs from the tear notch outgoing crack at an angle towards the line of weakness until it hits this then hits and sits along the line of weakness to the longitudinal edge of the Bag so that a corner of the bag is removed cleanly.
  • the Angle between the top edge of the bag and the center line of the tear notch in a range between 45 ° and 90 °, the separation of a corner of the Bag favors.
  • tearing open according to another embodiment the invention can be facilitated by adding another line of weakness is provided, from the tip of the tear notch to at least approximately runs to the line of weakness.
  • said recess is close to one of the longitudinal edges of the Bag, which means that when torn only a small piece of the bag with one short tear line must be torn off and also the opening that arises is located close to the side edge and is therefore easily accessible.
  • foil bags In the above-mentioned foil bags according to the It is also known in the art to enclose a drinking straw in a foil bag, the end of which protrudes into the recess. After opening the bag protrudes the drinking straw comes out of the opening and is ready for use.
  • opening such bags especially when the straw is about is arranged diagonally in the bag, causes the stuck in the recess Drinking straw has a certain resistance, which often leads to annoying splashes.
  • This hindrance to tearing can also mean that the Drinking straw is kinked.
  • This disadvantage is due to a preferred embodiment solved the invention, in which a drinking straw with the according to claim 1 tear-open notch provided at the top of the bag is combined, see above that the tearing cannot be hindered by the drinking straw.
  • FIG. 1 shows a schematic, perspective view known beverage bag with a straw included therein 6.
  • the Bag consists of two superimposed film webs 1 and 10, which are passed through two longitudinal sealing seams 3 and 4 are connected to one another.
  • a floor 2 is formed by an inserted piece of film, which is also by sealing seams 13th is connected to the two film webs 1 and 10 and that enables the bag to stand freely on a horizontal surface.
  • Pointing at the top the bag has a head seal seam 5.
  • a recess 9 is provided, into which the drinking straw 6 projects.
  • the length of the Drinking straws 6 are dimensioned so that their lower end abuts the bottom 2, while its upper end protrudes into the recess 9.
  • the recess 9 is arranged near the longitudinal sealing seam 3 in the example shown. It But such bags are also known in which the recess approximately in the center of the head seal seam is provided.
  • a line of weakness 7, for example can be produced by means of a laser beam runs parallel to the top of the bag across its entire width. The distance of the Line of weakness 7 from the upper edge is chosen so that it over the Recess 9 and next to the recess in the area of the head seal seam 5 runs.
  • a tear originating from the tear notch 8 continues along the weakening line 7 and gives in the area of the recess 9 a small opening from which the drinking straw 6 protrudes.
  • the tip of the tear notch is sufficient 8 close to the interior of the bag in the area of the recess 9. It it is obvious that deviations in the width of the relatively narrow Longitudinal seal 3 and at the depth of the tear notch 8 easily to leaks can lead if the tip of the tear notch is too close to the interior of the bag comes.
  • Foil bags with weakening lines are also known, which are not run parallel to the head seal seam, but for example diagonally across a corner of the foil pouch.
  • Such lines of weakness do not have to either run rectilinearly, but can be curved, for example, such that the corner of the foil pouch that has to be torn away has the shape of a circular sector Has.
  • the effort to create such lines of weakness is considerable larger than that for producing substantially parallel to the head seal seam running lines of weakness.
  • Figures 2 and 3 show an embodiment of an inventive Foil bag in a side view, being the same Parts of the same reference numerals were used as in Figure 1.
  • Figure 2 shows the bag before opening and Figure 3 shows the bag after opening.
  • the bag is not mandatory two film webs 1, 10 are required. Rather, a single sheet of film be folded over on one long side of the bag, so that, for example the longitudinal sealing seam 4 shown in the figures is eliminated.
  • the Bags also do not necessarily have an inserted bottom.
  • Figure 2 shows a tear notch 11 at the top of the bag. The top seal seam 5 is on this point wide around the recess 9 receiving the drinking straw 6 form.
  • the tip of the tear notch 11 also comes in case of inaccuracies when sealing or when making the tear notch 11 in no case in the Close to the inside of the bag, causing leakage can be excluded.
  • the center line more precisely the bisector of the V-shaped Tear notch 11 is not parallel to the sides of the bag, but is inclined downwards to the side on which the drinking straw 6 is in the recess 9 is included. Consequently, when the bag is opened, the Crack starting from the tear notch 11 in the direction of the upper part of the Drinking straws 6 extend, as illustrated by the tear edge 12 in FIG. 3 is.
  • a further line of weakness can 14 are provided, which tear the films starting from the tear-open notch relieved to the line of weakness 7.
  • This further line of weakness can be parallel to the longitudinal seal 4 or preferably as above for the tear notch 11 described inclined to this. Since this is another Line of weakness 14 completely within the area of the head seal seam located, it can also be designed as a perforation line, for example.
  • the line of weakness 7 does not appear as shown must extend over the entire width of the bag, but in principle a line of weakness that extends from the longitudinal seal would suffice 3 extends into a region approximately vertically below the tear notch 11. It may also be sufficient to use the weakening line 7 only on one of the two Foil webs 1, 10 to be attached, but is preferably on both foil webs such a line of weakness exists. Otherwise, the Line of weakness 7 of course also by other methods than by means a laser beam can be produced, for example by cutting or Cracks.
  • the films used to make the bag are preferred multilayer films, for example the following material combinations exhibit. PETP / PE, OPP / PE, PETP / AI / PE, OPP / AI / PE, PETP / AI / OPA / CPP or PETP / AI / CPP.
