Definitions

  • the invention relates to a standing plastic packaging made of flexible, sealable material, with a bottom, with side walls, with a sealing seam connecting the side walls and with a pouring device attached in the upper region of a sealing seam and having a base body, the axis of which is perpendicular to the base body.
  • Known filler packs of this type are currently sold commercially as refill packs for cleaning agents or bathing agents.
  • the material of the pack is sealable plastic in several layers in order to obtain a tight and so rigid pack that it is stable even when filled.
  • the side walls are flattened at the top and connected to a longitudinal sealing seam that extends to the bottom, while the bottom is sealed in, thereby spreading the lower edges of the side walls so that the known wider and narrower pack at the bottom can stand on the bottom of the side walls.
  • a closure of various designs is provided in the upper region of a side wall, with the aid of which the end user can pour out the liquid and, if necessary, reseal the package.
  • the known construction of a pull tab or another known construction with a screw cap or the like can be used here as a pouring device.
  • a basic body made of a stiffer material than the rest of the packaging material, in order to either glue or seal a covering and peeling strip or to seal or to attach a hollow nipple on which a screw cap , Clamping cap or the like can be applied.
  • an imaginary plane is laid through the edge of the pouring opening, the axis of the pouring device which extends through the center of the pouring opening extends perpendicular to this imaginary plane. This condition applies to base bodies of flat shape as well as those of curved shape.
  • the base body of a pouring device with a screw cap is usually flat and is formed by a flange which surrounds the pouring opening.
  • the annular base body of the pouring device is mounted in the upper region of a side wall at too great a distance from the side sealing seams, so that the base body when unscrewing or unscrewing the screw cap without support in the soft, flexible material that surrounds it , rotated and folded.
  • a torque arm is missing.
  • Another disadvantage is that when applying a torque and the force of the end user to actuate the pouring device exerts a pressure on the filling material, so that the filling material swells past the half-unscrewed cap and drips down before the first desired pouring.
  • the pouring device has been integrated into a sealing seam connecting the two opposite side walls at the top by welding.
  • the base body of the pouring device has been given a specific configuration which could be roughly compared with a ship's body in plan view.
  • a nipple with an external thread is formed on this base body.
  • the first-mentioned known and many other superplasticizer packs in common is the disadvantage that the axis of the pouring device, which is perpendicular to the base body, is aligned without special attention once in this position and once in that position in space, with the result that in all cases in which the axis protruding downward outside the pack, ie in the angular range between horizontal and vertical, liquid inevitably collects next to the closure body (e.g. screw cap). When the closure body is removed for the first time, unwanted liquid can leak out immediately.
  • the closure body e.g. screw cap
  • an imaginary flat base area which lies horizontally and on which the bottom of the pack stands.
  • the explanations here do not relate to packaging lying on its side or upside down due to the corresponding repackaging, but it is assumed that the bottom is on the horizontal basic level.
  • the bottom of the packing can be designed in any way, either even Form plane or be extra sealed between two side walls, so that the package stands on the lower edges of the side walls, as explained in connection with the known package described above. It is therefore logical that the side walls of each pack rise from the floor and are connected in some way at the upper end, for example by folding and or sealing.
  • the object of the invention is to improve the pouring process of known stand-up pouch packs and to make it easier for the end user, without the manufacturer having to use complicated tools in the creation of the standable flow agent pack of the type mentioned at the outset.
  • this object is achieved in that the upper region of the side wall, where the pouring device is attached, is folded in to form two outer edges and one inner edge, the inner edge of the fold is connected to a sealing seam connecting the side walls, and the base body of the pouring device in Area of the lower end of the fold is attached.
  • the features according to the invention provide a holder and support for the pouring device, although the material of the plastic packaging surrounding the pouring device is flexible and sealable, e.g. a plastic film.
  • the spout may be attached to a side wall in various ways, e.g.
  • the pouring device is nevertheless given a certain fixation in space, so that the opening, pouring and resealing is easier for the end user.
  • the package manufacturer can attach the pouring device to the side wall with simple means, e.g. weld on. The folding ensures that the opposite side wall does not fall from the inside and back against the pouring opening and closes it unintentionally while preventing pouring.
  • the fold-in also advantageously enables the pack manufacturer to fasten the base body in a spatially defined position on the side wall in such a way that there is no longer any product in the pouring opening which would drip in an undesired manner when the pack was opened.
  • the straight axis which is directed outside the pack and which is perpendicular to the base body of the pouring device also has the level base surface on which the bottom of the package is located encloses an angle 0 0 °.
  • the package manufacturer can bring the pouring device into the defined position desired by observing the alignment of the straight axis. It can be achieved in this way that the axis which is perpendicular to the base body of the pouring device and points outside the pack (think a straight arrow) is at most approximately horizontal, preferably with a more or less large vertical component at an angle or points all the way up so that there is practically no horizontal component left. Then it is ensured that the filling material cannot collect under the screw cap and that no filling material drips out undesirably even when it is opened for the first time.
  • one end of the sealing seam namely the front end, which faces the pouring device, is located in the upper region of the upper end of the fold-in.
  • the sealing seam considered here connects two mutually opposite side walls, and this at the top of the pack.
  • a stand-up pouch pack or a stand-up superplasticizer pack which in a particularly advantageous manner has a square, preferably a trapezoidal bottom.
  • two side walls protrude from the lateral bottom edges in such a way that they meet in a top line overall or at least in the front region (in the front is the side with the pouring device). Accordingly, there is a front bottom edge from which a front wall runs to the common upper line of the two side walls.
  • This common upper line can also be called the front longitudinal edge.
  • a rear wall extends over the rear bottom edge, which ends in a rear upper edge running perpendicular to the longitudinal edge.
  • An approximately triangular top wall can also be provided between this and the front longitudinal edge. If you look at such a package from from in a direction parallel to the flat base on which the floor stands, you will see a front height projection, ie a height from the front floor edge up to the front longitudinal edge. Likewise, if you look in the opposite direction from the rear onto the back wall of the pack, you can see a rear height projection. This extends from the bottom edge at the bottom to the top edge at the rear.
  • the side walls are flat, but in fact they will bulge due to the flowable filling material.
  • the front wall can nevertheless be triangular, the rear wall trapezoidal or, preferably, triangular.
  • the flat floor lies on the imaginary horizontal base plane, and the triangular front wall stands approximately vertically high, while the side walls are inclined and in accordance with the legs of the triangle of the front wall Meet vertically above the floor along the longitudinal edge.
  • Another preferred embodiment is based on the model described above and only changes the feature that from the front upper tip, i.e. above the front wall at the top of the triangle, sealing up to the rear upper edge.
  • a bottom fold is known from the general production of liquid packs from paper coated with plastic, in which a transverse sealing seam is provided from a tube in the bottom region, the ends of which each represent the tips of triangular flaps opposite one another with respect to the bottom. These triangular flaps are folded over in the known liquid packs and attached to the floor in order to provide a flat, square base for the known liquid pack. Also with the package described here made of flexible, sealable material, e.g. a plastic film, triangular flaps can be provided next to the front and / or rear bottom edge, which can be folded over and sealed in a manner similar to the known liquid packs. Along these fold edges, i.e. of the front and / or rear edge of the floor, it is also possible to provide a sealing seam and to design this as a dividing line by which the triangular tab is separated from the floor.
  • a transverse sealing seam is provided from a tube in the bottom region, the ends of which each represent the tips of triangular flaps opposite one another with respect to the bottom
  • a transverse sealing seam running from the front to the rear bottom edge can also be made in the floor. Additionally or alternatively, an upper transverse sealing seam can also be attached to the upper ends of the side walls. These transverse sealing seams can be curved, but preferably straight.
  • the pack according to the invention can also be designed such that the upper transverse sealing seam consists of at least two straight and / or curved sections. Then the upper transverse sealing seam does not run in a straight line over the entire upper area of the package but is divided into different sections. This allows you to reduce the head volume of the pack, shift the center of gravity down and improve the pouring.
  • both the inner edge and the upper edge of the fold extending transversely thereto are straight and if the upper edge encloses an angle between approximately 0 ° and 90 ° with the flat base surface.
  • the folding begins again in its lower region at or near the pouring device, the upper edge being turned more or less downward from the uppermost boundary line of the pack at an angle. If you lay a straight line through the upper edge, this leaves the above-mentioned upper limit line of the package, which is to be thought of as horizontal, although it can also be set at certain angles to the horizontal.
  • the folding creates an angle which can be driven from an initial 0 ° in one limit position for other embodiments to another limit position in which the angle is approximately 90 °.
  • the line in the upper edge can even be turned a little over 90 °, so that this angle could be designated as approximately 100 ° .
  • the axis of the pouring device can be adjusted differently by appropriate configuration of the folding. In this way, the manufacturer can prefer one or the other angle setting depending on his objective and the economic calculation.
  • the inner edge of the fold is bent or bent such that the upper end section of the inner edge lies essentially parallel to the upper end section of the outer edge of the fold.
  • the outer edge also changes accordingly, so that it has different sections, the upper end section being steeper than the lower section.
  • the upper portion of the outer edge is substantially vertical or at least below about 90 ° to the outer upper limit line of the package.
  • the upper end section of the inner edge should run parallel to this upper section of the outer edge.
  • the folding can lead to different positioning of the axis of the pouring device.
  • the outermost upper limit line of the pack which runs approximately horizontally, can be attached as a straight cross-seal seam, and then the top edge of the fold runs in this cross-seal seam Seal the horizontal transverse sealing seam better and more conveniently by sealing.
  • the fold-in defines a fixed point for the pouring device, so that the latter is better held during opening movements and the user does not have to support the filling material when actuating the pouring opening.
  • the pouring device is arranged according to the invention in an unfilled part of the package, so to speak in the area of the head space, so that there is no pressure increase in the filling material, even if the end user presses something against the pouring device.
  • FIG. 1 schematically shows the side view of a pack according to the invention, provided with the folding, of a first embodiment
  • FIG. 2 shows a view similar to FIG. 1, but of a second embodiment in which the inner edge is bent
  • FIG. 3 is a view similar to that of FIGS. 1 and 2, but of a third embodiment, which in principle has the same requirements as that of FIG. 1, namely a straight inner edge,
  • FIG. 4 shows, in perspective, a preferred fourth embodiment of the superplasticizer pack in a geometric representation
  • Figure 5 is a plan view of the filled package of Figure 4.
  • FIG. 6 shows a broken and schematic cross-sectional view along the line VI-VI of FIG. 2.
