Definitions

  • the invention relates to a flexible container according to the preamble of patent claim 1 and to a method for producing such a container according to the preamble of patent claim 14.
  • Flexible containers have been known for some time and exist in various embodiments. Worth mentioning at this point, for example, refill packs for liquid products, such as liquid soaps or detergents, but also packaging for gel-like substances, such as toothpaste or solids, such as detergent or cat litter, to name just a few examples.
  • Such flexible containers are usually made of a film or laminate material that is inherently flexible and that allows for a variety of configurations of such flexible containers. These containers may for example have a bag or tubular bag form or else be designed can-shaped.
  • packaging all these flexible forms of packaging have in common that the flexible packaging per se does not have a stable outer shape, but that the outer shape of the packaging on the one hand by the packaging construction and geometry and on the other hand by the nature and quantity of the respective in-package contents results.
  • the outer shape of the packaging thus adapts, as far as the packaging construction permits, to the respective contents and degree of filling and, depending on the type of contents, "slims" if necessary with increasing emptying of the packaging.
  • An important advantage of such more flexible consists in that such a flexible package does not rigidly retain its original packaging shape after complete emptying, but can be folded or rolled or crumpled, and thus easily disposable due to its reduced volume due to folding, coiling or crumpling.
  • a disadvantage resulting from the flexible structure of such flexible packaging forms is that the handling of such packages, especially when they are opened, is difficult to control, since the packaging, for example, depending on the point of application depresses, resulting in a open packaging in the worst case may cause contents to be pushed uncontrollably out of the opening.
  • Another way to make flexible packaging more manageable was to provide the flexible package with a controlled opening area, which, for example, was that the package could only be partially opened. Such a procedure, however, meant a complicated packaging construction, because a part of the packaging had to be specially prepared, so that only this part can be opened. In addition, by providing a special opening area for a user, the handling was made Opening the packaging complicated because the user first had to realize how to open the packaging and also had to follow certain measures to open the packaging in most cases.
  • a controlled opening area was, for example, the provision of a spout or opening tab which covered a correspondingly small opening of the flexible package.
  • the object of the invention while avoiding the above-mentioned problems, is to provide flexible packaging with improved handleability, which offers a consumer the solution that is familiar to him for opening the packaging and from the liquid, gelatinous, viscous, powdery and / or particulate filling material Exercise of manual pressure on the flexible packaging container targeted and well-dosed emptied, for example, in a kitchen container, such as a pot, plate or the like can be filled, the flexible packaging also offers the advantage of complete emptying by squeezing even with large bag diameters. Furthermore, the object of the invention is to provide a method for producing such a flexible packaging.
  • the object is achieved by a flexible container having a receiving space for liquid, gelatinous, pasty, lumpy and / or powdery product, which is bounded by the receiving space surrounding side walls and optionally a bottom, and a receiving space to its side, preferably in Use position up, final tear strip, which is substantially completely removable to open the container, the side walls inside the container along a portion of the longitudinal extension of the tear strip to form an opening limit permanently connected, so that the container even after a substantially complete removal of the tear strip only partially open.
  • the flexible container according to the invention can be opened in a manner, respectively, can be opened without destroying the container only in such a way that the container is opened only partially when opening in each case.
  • This is inventively ensured by the fact that the side walls of the container, which limit the receiving space side, container inside are connected to each other so that after opening the container by removing, ie tearing off the tear strip a defined by the connection of the side walls of the container barrier remains, which acts as leakage protection.
  • This barrier limits the opening of the container according to the invention in such a way that contents can be purposefully removed only at this barrier over from the container.
  • the barrier, or the connection of the side walls of the container, thus acts as an opening limit.
  • novel flexible packaging container according to the invention can be opened in an advantageous manner by tearing off the tear strip, but the packaging container according to the invention is not opened, as previous packaging containers over the entire length of the tear strip, but only a small opening whose size their associated opening limit is defined.
  • the opening limitation is arranged according to the invention adjacent to the tear strip and can be designed according to the invention as long as desired.
  • the size of the pouring opening of the novel flexible packaging according to the invention can be specifically adapted to the respective contents, it being possible, for example, for liquid products a very small pouring opening, i. a very elongated opening restriction, and for highly viscous or particulate contents a larger or larger pouring or discharging opening, i. a very short opening limit to produce.
  • the flexible packaging according to the invention is thus very versatile and adaptable to virtually any packaged goods.
  • the container according to the invention is designed as a flexible bag packaging, in particular as flat bag, bag (SUP) and / or tubular bag packaging, with a front and a rear wall.
  • SUP flat bag, bag
  • tubular bag packaging with a front and a rear wall.
  • the closed state of the bag packaging has these longitudinal and transverse edges, which are interconnected and define the receiving space.
  • at least one of the longitudinal or transverse edges is designed as a tear strip.
  • a pouch packaging according to the invention may in principle also have a round, oval or other geometry, wherein the longitudinal and transverse edges may be formed in such a case as a single circumferential edge.
  • a portion of this peripheral edge may be formed as a tear strip, wherein adjacent to this tear strip is formed by a connection of adjacent to this tear strip container inside side walls an opening boundary.
  • the respective container-side side walls of the flexible container according to the invention respectively the flexible, for example, cuboid or spherical bag packaging according to the invention, either directly connected to each other or, alternatively, by means of the respective side walls connecting film or membrane can be interconnected ,
  • the latter variant is particularly advantageous in can, cuboid or spherical containers.
  • the opening limitation is formed as a seal connecting the front and the rear wall of the container, in particular the bag packaging, or, as mentioned above as a membrane.
  • An embodiment of the opening limitation as a seal or gluing is particularly advantageous, since a seal or gluing in the form of a sealed seam or adhesive seam can be realized in a very practical manner after a filling of the product into the container according to the invention by a simple compression of the respective mutually associated side walls. In this way, it is possible to fill a product at maximum opening of the container according to the invention in these and the opening restriction only then, ie only after filling, to attach to the container according to the invention.
  • the mutually associated side inner walls may be coated with an adhesive that allows for a compression of the side walls connecting the side inner walls.
  • the respective side inner walls may be provided with a sealable material, such as polyethylene or polypropylene, or may be made of such a material so that the respective side inner walls, for example, with thermal sealing jaws or can be connected by ultrasonic sealing when the respective side inner walls are brought into contact with each other.
  • the respective seal or adhesive line or pattern in particular in the form of a network, diamond or comb pattern, preferably with in the direction of the tear strip (30) facing peaks or spikes, formed.
  • the seal pattern is serrated or comb-shaped and the pointed ends, respectively spikes, are directed towards the tear strip or a seal seal, so that penetration of filling material in an optionally present, in the Usually very small, space between the seal seal and opening limit is inventively avoided and such a potential gap is thus sealed.
  • filling material penetrates into the intermediate space between the tear-off strip and the opening limitation and deposits there.
  • the opening limitation according to the invention is arranged immediately adjacent to the tear strip.
  • the opening limit may also be arranged at a certain distance from the tear strips.
  • two spaced apart and oppositely extending opening boundaries may be provided such that the liquid product initially with emptying the packaging along the further inside in the receiving space arranged opening boundary along and out the opening adjacent to this opening boundary and then running out along the opening boundary located farther out in the receiving space and out of the packaging adjacent to that outer opening boundary.
  • Such an embodiment prevents a very spill over very liquid products in a very effective manner, since the further outwardly and adjacent to the tear strip arranged opening limit serves as another barrier. To emptying the liquid filling material, this must thus pass between the oppositely disposed opening boundaries and can only then emerge from the container.
  • the tear strip comprises a seal seal which extends substantially over the entire length of the respective tear strip, in particular the respective longitudinal or transverse edge.
  • the seal seal ensures that the container according to the invention is tightly sealed before being opened.
  • the respective other longitudinal and transverse edges can likewise have sealing seals or can be designed per se as a sealing seal.
  • the sealing seal is covered and / or supplemented with a visual seal which may have a design-related, visually appealing feature.
  • an opening aid in the form of a weakening line in particular an embossing line or a laser-weakened line, and / or in the form of a tear strip and / or in the form of a region in which the laminate has a predefined preferred shape can be formed between the opening delimiter and the tear-off strip Tear direction has, for example, monoaxially stretched. In this way, the opening of the container according to the invention can be facilitated. Furthermore, such an opening aid allows a straight elevation, which is helpful in particular with regard to reliable operation of the opening mechanism according to the invention.
  • a tear-in aid is provided according to the invention on one side of the weakening line or on both sides of the weakening line.
  • Such is inventively attached, for example, in the form of a respective visible notch and / or a respective cut in the laminate of the respective side seam or in the two respective side seams at the intended locations.
  • Such an entry aid according to the invention usually also in the printed image of the respective pouch packaging according to the invention and indicates the consumer or user where he has to tear to open the pouch packaging.
  • the respective tearing aid is mounted according to the invention in each case at a level between the seal seal and the opening limit.
  • the opening limitation extends from a first side of the respective longitudinal or transverse edge, in particular substantially parallel to the tear strip, in the direction of the other ie second side of the respective longitudinal or transverse edge.
  • This embodiment allows a squeezing of the container according to the invention, since it has only a single opening, namely on one side of the respective longitudinal or transverse edge.
  • the opening boundary extends with a spacing from a first side of the respective longitudinal or transverse edge, in particular substantially parallel to the tear strip, in the direction of the other, i. second side of the respective longitudinal or transverse edge.
  • the opening boundary namely in the direction of the second side of the respective longitudinal or transverse edge of a pouring opening may be arranged, while on the other side of the opening boundary, i.
  • An air hole may be provided in the direction of the first side of the respective longitudinal or transverse edge, so that, in particular, liquid contents can flow out without clucking and without any significant deformation of the container.
  • a distance of the opening delimitation from the first side of the longitudinal or transverse edge is according to the invention in the range of 0.5% to 8%, preferably in the range of 0.8% to 5% and particularly preferably in the range of 1% to 3.5%. , in each case with respect to the clear width of the receiving space receiving space side of the opening limit.
  • the partial opening of the container is according to the invention in the range of 5% to 80%, preferably in the range of 8% to 50% and particularly preferably in the range of 10% to 30% with respect to a complete opening of a container without opening limit.
  • the container is made of a film material, in particular a laminate, preferably a barrier layered laminate, for example aluminum laminate or a metallized laminate.
  • the decisive idea of the invention is to provide, after filling and closing a flexible container, in particular a bag-like container, or a bag-like packaging, an additional sealing seam below the sealing seam and below an opening line designed as a tear line, which does not extend over the entire head width runs, but leaves a part of the bag head after tearing open.
  • This sealing seam can be combined with existing thermal sealing jaws e.g. On Toyo filling machines for prefabricated bags are attached, but also with an additional station or by means of ultrasonic sealing.
  • a straight elevation between the sealing seam and the reduction seam formed as an opening boundary is advantageous.
  • a monoaxially stretched film or a monoaxially stretched laminate such as terols can be used as a material for producing the package.
  • the front and back of the package may be made from two separate blanks or alternatively folded over from a piece of laminate.
  • a remaining flag namely in the form of an offset can be adjusted, which comes at the opposite Beutellssensnaht, ie at the end of the elevation can lead to the stop of the elevation and secure a retention of the tab on the bag can.
  • the remaining tab may remain over the non-open end, ie, above the reduction seal. without this interfering with the emptying of the product.
  • the production of the packaging according to the invention is significantly simplified if the tear strip is separated uniformly over the full length and possibly gets stuck only at the seal at the end of the tear-off strip.
  • Such an embodiment is preferred in view of a user-friendly operation.
  • the reduction seal offers sufficient security on the part of the manufacturer and the consumer can always open the entire bag head. Depending on the contents to be filled, the reduction seal can also already be applied to prefabricated bags.
  • the package according to the invention provides a simple but effective and versatile solution to the problem of uncontrolled emptying of a flexible container and ensures a targeted metered and controlled emptying of such inventive flexible container.
  • a further significant advantage of the invention further consists in that, on the one hand, it enables a simple filling of contents into the container according to the invention and does not impair the filling process.
  • the use of existing technology, such as heat or ultrasonic sealing easily possible.
  • the desired opening width can be flexibly adapted by the respective filler to the respective filling material and adjusted accordingly.
  • Fig. 1 shows a container 10 according to the invention, which is designed as a bag package.
  • the bag packaging consists of a front and a rear wall, the are sealed together along their longitudinal edges 50 and their transverse edges 60 defining a receiving space 20.
