Definitions

  • the invention relates to a tubular bag according to the preamble of patent claim 1.
  • Tubular bags of the type in question are well known and are generally used for storing, storing and transporting as well as in marketing of liquid, pasty and solid content substances, including u.a. the light weight and the ease of design and printability of these tubular bags and packages produced therefrom has proven to be extremely advantageous.
  • Tubular bags that have a standing or standing floor have proven to be particularly popular. Such tubular bags are usually provided with a bottom having a V or W-fold. These give the tubular bag its stability.
  • Such tubular bags have not only a bottom-side termination but also a head-side conclusion.
  • This head-end conclusion can be designed, for example, as a spout, which is sealed between the tubular bag forming film or laminate layers.
  • This attachment of a spout is quite expensive and it can In addition, leakage problems occur.
  • a spout as a rule not the entire possible cross-sectional volume of the tubular bag is accessible, but it is only possible to pour out liquid or powdered tubular bag contents or to squeeze pasty bag contents from the tubular bag.
  • Another way to close a tubular bag head side is simply to seal the side layers forming the tubular bag together and attach a lateral notch to the package for opening the package, by means of which a tearing of the packaging is possible.
  • Another opening variant is finally in the use of a pair of scissors, by means of which an upper portion of the closed tubular bag is separated and removed, so that the inner volume of the tubular bag is then freely accessible.
  • this variant allows a clean separation of the tubular bag closing tubular bag section, but requires that always a pair of scissors must be at hand.
  • an unclean scissors there is a risk of contamination of the cut edges and also of the tubular bag contents, which may thereby become unusable.
  • the object of the invention is to provide a tubular bag of the type mentioned, which is inexpensive to manufacture, can be easily filled and can be opened in a hygienic way easily and without tools so that the inner tube bag is easily accessible.
  • This object is achieved by a tubular bag according to claim 1.
  • this object is achieved by a tubular bag with a tubular pouch body and bottom, in particular standing and standing floor and lid, wherein the lid and / or the bottom has at least one about diagonal over the lid and / or bottom extending peel seam.
  • An essential point of the invention is that it can be completely dispensed with a head-side opening possibility to attach the tubular bag, since the lid and / or bottom of the tubular bag by tearing or mounting the
  • Peelnaht can be opened.
  • the tubular bag can be opened only to a small extent, so that a simple pouring of liquid from the tubular bag is possible.
  • the peel seam is formed according to the invention either as a lap seal or as a fin seal. Furthermore, the peel seam has at least one unsealed grip area.
  • the lid and / or bottom of the tubular bag are each formed flat. Alternatively, the lid and / or bottom may comprise a V or W fold, with the peel seam extending approximately perpendicular to the V or W fold. It should be emphasized that it is within the scope of the invention to make the lid of the tubular bag flat, with a V or W fold and the bottom of the tubular bag also flat, with a V or W fold, regardless of the lid design.
  • the peel seam is designed as a fin seal
  • gripping areas assigned to the respective film ends are detected with one hand each to open the same.
  • the film ends are then pulled apart in the direction of the edge of the bag, in particular substantially parallel to the folding of the V or W fold, so that the peel seam opens with release of the tubular bag interior.
  • the peel seam may also be designed as a lap seal.
  • This opening variant is particularly advantageous, since it is possible to open the floor with only one hand, while the other hand holds the tubular pouch body. It should be emphasized that this opening variant is particularly suitable for solid and pasty Schlauch zucchini- ingredients.
  • the lid, the bottom and the tubular pouch body are each separate components which are glued together and / or sealed to produce the tubular pouch.
  • the tubular bag may also be folded and sealed from a single sheet of foil, the lid, bottom and tubular bag body consisting of a single foil blank.
  • a seal strip is wider than the other seal strip, the wider seal strip before use of the tubular bag, ie before the opening thereof, on the narrower seal strip, in particular on the lid and / or bottom surface, is folded. In this way it is possible to cover the opening area of the fin seal by means of the wider seal strip and to protect it from contamination. This is particularly advantageous if the tubular bag is used as packaging for food.
  • At least one sealing tip directed into the tubular bag interior is provided in the region of the peel seam.
  • a sealing tip it is possible to prevent a tubular bag from being cambered, for example, during heating, since the inwardly directed sealing tip peels off when a predefinable internal pressure is exceeded and allows venting of the tubular bag.
  • the sealing tip in the open state with the environment via a labyrinth, a sponge, a V bland or the like acting as a throttle device in fluid communication is prevented by the spray that liquid or pasty ingredients from the tubular bag.
  • tubular pouch body itself and its bottom and the lid of the tubular pouch is relatively stiff. This is particularly advantageous if the tubular bag contains liquid or pasty ingredients. In the case of solid ingredients, these can give the tubular pouch body itself a certain strength.
  • the tubular pouch body is produced from a square or rectangular foil blank, wherein the overlapping edge regions are joined together by a fin-seal and / or lap-seal seal to form a tubular body.
  • the hose bag can be made as part of an extruded film tube, which is preferably seamless.
  • the tubular pouch body is preferably made of a laminate, in particular an aluminum laminate, with at least one sealing layer and optionally at least one barrier layer.
  • the barrier layer is preferably made of SiO 2 , ethylvinyl alcohol (EVOH), an oriented polyolefin, in particular polypropylene (OPP) or a metal foil, such as an aluminum foil.
  • the bottom of the tubular bag and its lid are made substantially from the same materials as the tubular bag body. As a result, a very cost-effective production of the tubular bag is possible, since both the lid and the bottom of the same film or the same laminate are produced, as the tubular bag body itself.
  • the later tubular bag body forming film before a formation of the tubular pouch body or a portion of an extruded tube, which are each separated to form the lid.
  • the bottom and / or the lid of the tubular bag according to the invention is preferably produced by first forming the lap or fin-seal peel seam from two film or laminate flat bodies. Subsequently, the bottom and / or the lid is folded V- or W-shaped and sealed in the tubular pouch body, so that the sealed handle portion of the peel seam is accessible from the outside.
  • Both the lid and the bottom and / or the tubular pouch body have a thickness of the film or of the laminate in the range from 50 ⁇ m to 1000 ⁇ m, preferably 100 ⁇ m to 500 ⁇ m and particularly preferably 150 ⁇ m to 350 ⁇ m.
  • a thickness of the film or of the laminate in the range from 50 ⁇ m to 1000 ⁇ m, preferably 100 ⁇ m to 500 ⁇ m and particularly preferably 150 ⁇ m to 350 ⁇ m.
  • the lid, the bottom and the tubular bag body itself sterilizable, so that food and stimulants can be filled into the tubular bag and hygienically packaged therein.
  • FIG. 1 is a schematic representation of a tubular bag according to the invention from below.
  • FIG. 2 shows a schematic illustration of a further tubular bag embodiment according to the invention from above;
  • Fig. 3 is a further schematic representation of an alternative inventive embodiment of a tubular bag from above.
  • An inventive tubular bag 10 is made of two films forming the tubular bag body, which are sealed together along their respective side boundaries and on the head side.
  • the tubular bag 10 On the bottom side, the tubular bag 10 is closed with a base 20 having a W-fold.
  • the bottom has a fin-seal seam 40 serving as peel seam 40.
  • the peel seam 40 is disposed on the bottom 30 such that unsealed handle portions 50 of the fin seal seam are conveniently accessible. Further, the peel seam 40 is not centered but arranged eccentrically along the W-fold, so that the tubular bag 10 is evident when the peel seam 40 tears in one direction by about 40% and in the opposite direction by about 60%.
  • FIG. 2 Another embodiment of the invention from a tubular bag is shown in Fig. 2.
  • This view shows the lid 60 of a tubular bag 10, with which the tubular bag body 20 is closed at the top.
  • the lid 60 is closed by means of fin-seal 70, wherein the two seal strips of the fin seal 70 each have an unsealed handle region 50 which can be gripped.
  • the tubular bag 10 can be partially or completely opened so that the tubular bag interior of the tubular bag 10 is accessible over the full circumference of the lid opening.
  • FIG. 3 shows an alternative embodiment of a lid 60 designed to close a tubular bag 10.
  • the lid 60 is in turn closed by means of a fin seal 70 which forms a peel seam 40.
  • a seal strip with an unsealed handle region 50 is wider than the other seal strip, the wider seal strip being folded over the narrower seal strip in that the unsealed handle region 50 of the wider seal strip comes to lie on the cover foil of the tubular bag 10.
