Definitions

  • the invention relates to a package for flowable filling material with a tube-forming side walls, bottom and top wall and with a closable pouring device, all parts of the package being made of plastic and each of two shell-shaped parts each having a whole side wall, two respectively opposing adjacent fractional side wall parts forms a fragmentary bottom part and a fragmentary upper wall part and is provided with a flange-like edge on the outer circumference of the shell-shaped part and wherein both shell-shaped parts are connected to one another.
  • Packings for liquids are commercially available.
  • the consumption of plastic is often considerable, so that such packages are reluctant to use as disposable items or single-use packaging.
  • simpler pouring devices and closures can be used to reduce manufacturing costs and material consumption.
  • liquids cannot be filled and packaged, so that the scope of such packs is too limited.
  • Still other packs have lids specially designed by injection molding, deep-drawing or other known manufacturing processes for the processing of plastics, which are production-related and exclude a good possibility of stacking.
  • each shell-shaped part on the fractional top wall part has a fraction, an approximately cylindrical pouring device, and is sealed on the edge with a plastic film resting on the edge in the form of a web, projecting over parts of the container forest the approximately cylindrical-shaped closing edge of the pouring device extends to both bowl-shaped parts, that the web does not extend into the bottom, and that the thickness of the plastic film is 0.01 to 0.5 times, preferably about 0.1 times the thickness of is bowl-shaped parts.
  • the correspondingly designed pouring device can thereby be manufactured more simply and more cheaply in such a way that the stackability is improved and reliably sealed closing devices can be provided which are easy to open.
  • the material thickness of the packing walls can be kept low, because the protruding edge in connection with the plastic film placed through it runs through the center of the packing like a stiffening frame.
  • Each shell-shaped part thus forms an entire side wall, adjoining two opposite side wall parts, a bottom part and an upper wall part, only part of the pouring device being formed on the respective upper wall part, for example by deep drawing or injection molding and for example half a pouring device on a half upper wall part.
  • the bottom of this shell forms the entire side wall, while the four edges of this shell are formed by the bottom part and the opposite upper wall part on the one hand and by a fractional (e.g. half) adjacent side wall part and the opposite fractional side wall part.
  • the shell-shaped parts are sealed together before they are connected to one another, preferably in a liquid-tight manner, for example by welding.
  • the respective shell-shaped part is surprisingly closed individually in the manner described above by a plastic film, which is welded onto the edges of the bowl-shaped part, for example.
  • the thickness of the plastic film can be considerably smaller than that of the bowl-shaped part, so that the passage of heat onto the edge of the bowl-shaped part is possible with little effort and, consequently, the production is considerably cheaper.
  • liquid packs are filled as much as possible during manufacture, and so far it has seemed impossible to a person skilled in the art to seal shell-shaped parts first with a plastic film, because he believed that afterwards the pack had to be opened again with particular effort and then closed again.
  • the cylinder edge of the pouring device is arranged in such a way that it extends over the web of the plastic film onto both shell-shaped parts, then simple and quick opening and subsequent reclosure is possible.
  • the finished pouring device consists in any case of, for example, an externally threaded cylinder rim, which is formed on the top wall or connected to it in such a way that the inner volume of the shell-shaped part - on each side of the plastic film - is filled by this cylinder rim, which is open to the outside, and can be emptied.
  • the cylinder edge thus has a pouring opening towards the outside and is connected towards the inside with the respective volume of the shell-shaped part without the plastic film running between them having a functional breakdown.
  • For closing the pouring opening can be used in a conventional manner, a screw cap or the like.
  • the web of the plastic film projecting beyond the edge of the shell-shaped part is cut off together with the said edge in the region of the pouring device and is otherwise laid twice and folded over onto the surface of the package. Since each bowl-shaped part is sealed liquid-tight by a plastic film and thus the plastic film protrudes over at least some edges of the bowl-shaped part, the result is a double-layered edge plus film web when connecting both bowl-shaped parts, but this can be folded over onto the surface of the package without difficulty . This not only makes the pack more stackable and more practical to use, it also gives it a more appealing look.
  • the edge and the applied web of the plastic film are cut off, e.g. such that the entire outer surface of the cylinder rim is free without a web, e.g. to apply a cap or other sealing part in a sealing manner.
  • the manufacture is further simplified by the fact that the edge of the shell-shaped part and the web of the plastic film projecting thereon move the surface of the pack in a U-shape from one side wall over the top wall to the opposite side wall in the middle and in each case at the edge between the side wall and Bottom folded over on itself. It is useful, for example, the floor without one to leave such plastic film web flat, because then the production of both shell-shaped parts in one piece is possible in such a way that the two parts are and remain hinged together via the respective base part.
  • the web of the plastic film and the thicker edge do not run around the package completely, for example over 360 ° or over all four sides of the package, if this is intended to be cut in the plane of the plastic film, but rather in a U-shape only on three sides, where the web forms a U and is arranged protruding over the edge of each shell-shaped part.
  • the long legs of the U can then be compared to the opposite side walls and the short web of the U connecting these long legs to the top wall.
  • the pouring device is arranged deep in a recess opposite the top wall.
  • the plastic material which without e.g. Cardboard or paper forms the actual wall of the entire package, is deep-drawn or injection-molded, in any case, the pouring device can be accommodated in the recess in the area of the top wall in such a way that even the most outstanding cap, a handle, a hinge or the like does not have the overall outer contour of the pack and in particular does not protrude beyond the outermost surface of the top wall. This makes the pack stackable and easy to handle when repackaging.
  • both shell-shaped parts are covered, closed by a single plastic film, and are connected in an articulated manner via an edge, which acts as a hinge, between the fractional base parts of the base.
  • the packaging is easier to fill, the filling process being carried out before the plastic film is finally sealed onto the edge of the shell-shaped parts, preferably in a considerably shorter time than if the filling were to be carried out through a small filling opening.
  • the fastening of the plastic film on the edge of the two shell-shaped parts stiffens the subsequent pack because both filled and sealed shell-shaped parts that are sealed to the outside are folded together along the edge acting as a hinge and combined to form the pack.
  • the plastic film reinforces the supporting effect of the edge, which moves the pack in a U-shape like a stiffening frame. This U is open in the area of the edge acting as a hinge.
  • the invention is expediently further designed in that the bottom of the bottom toward the edge increasingly deeper recesses having.
  • the outer contour of the base is nevertheless flat, in order to give the pack a good footprint.
  • This level is interrupted by the recesses mentioned, which can be notch-like depressions, for example.
  • the tool can be made more stable, particularly in the preferred embodiment in which the pack is formed from two approximately equally sized shell-shaped parts which are connected in the area of the base in a hinge-like manner described above - are coupled with each other and are therefore processed at the same time in the production essentially and with the same measures.
  • At least two opposite side walls each have a gripping recess. This creates a practical handle that is comfortable for the hand in the form of a recess, without the handle exceeding the outer contour of the package and therefore interfering with repackaging.
  • the plastic material of the pack is thermoformable, preferably a thermoplastic, especially polypropene.
  • PVC can serve as a thermoplastic, for example, and polypropene is also widely known in the art as polypropylene.
  • plastic materials When using such plastic materials, at least one and preferably both shell-shaped parts can be deep-drawn.
  • plastic materials are processed in the form of foils, sheets or sheets.
  • the new package then consists of perfectly reusable parts (in contrast to composite materials).
  • the polypropene can also be filled, with chalk, mica, talc, gypsum or the like being intended as fillers here.
  • filling levels of around 60% have proven to be favorable.
  • it has been shown that such filled plastic materials are deep-drawable and also sealable.
  • the in the individual figures in different embodiments and partially still unfinished pack has four tubular side walls, namely the below and next to the pouring device arranged front narrow side wall 1, which is composed of the two front half side wall parts 1 '; the rear narrow side wall 2, which is composed of the rear half side wall parts 2 '; a large side wall 3 and opposite a large side wall 4; the bottom 5, which is composed of two half floor parts 5 '; and the top wall 6 with the pouring device generally designated 7, the top wall also being composed of two halves of the top wall 6 '.
  • the pouring device 7 essentially consists of a cylinder rim 8, which is freely connected to the inside of the package as shown in FIG. 8 and has a pouring opening 9 to the outside as shown in FIG. 7, which has a cap after filling and complete or partial emptying 10 is closed, which can be closed, for example, via a thread 11.
  • part of the thread 11 can be seen inside the cap 10 and at the top an annular seal 12, with the aid of which the closure cap 10 is able to close the pouring opening 9 in a liquid-tight manner.
  • the viewer When studying the figures, the viewer recognizes that the entire package is composed of two shell-shaped parts I and II, which have approximately the same volume, so that in the case of a liquid package with the volume of one liter, half a liter of liquid can be accommodated in each bowl-shaped part.
  • the unfilled and open bowl-shaped part I or II is not shown here, but the viewer and reader can well imagine how each part is provided with an edge 13 on the upper outer circumference, which in the illustration in FIG. 8 is shown as a circumferential, flange-like one Edge of the same material thickness or thickness is shown as the shell-shaped part I or II is made.
  • a plastic film 14 is welded onto this flange-like and circumferentially U-shaped edge 13 of the shell-shaped part I or II in such a way that it lies flat on the edge 13 of the respective shell-shaped part I or II in the form of a web 15.
  • the entire shell-shaped part I or II is liquid-tightly closed, namely welded, because the plastic film 14, for example, which is thinner by an order of magnitude, can be very easily sealed onto the thicker flange-like edge 13 of the shell-shaped part I or II.
  • FIGS. 7 to 9 a special consideration of FIGS. 7 to 9 is recommended. although this one Abstracted embodiment other than that of Figure 1, the viewer recognizes the cut strip 15 in the region of the pouring device 7, which ends in particular in front of and behind the cylinder edge 8.
  • the cylinder edge 8 itself has a weld seam 18 in line with the web 15 of the plastic film 14 because it is composed of two half-ring parts.
  • FIG. 8 such a half ring for forming the cylinder edge 8 is shown in dashed lines behind the plastic film 14 and is shown closed with a semicircular plate 19.
  • FIG. 8 thus clearly shows the edge 20 of the shell-shaped part II, represented by a double dashed line, which merges into the U-shaped attachment edge 21 in the region of the later pouring opening 7.
  • the entire space, including the semi-cylindrical projection 22 in FIG. 8, which later results in the pouring device 7 or the cylinder rim 8, can be filled with filling material and closed by the plastic film 14.
  • both shell-shaped parts I and II are covered by a single plastic film 4, so that when folded over the state of FIG. 4 according to FIG. 3 according to FIG. 2 and ultimately for the finished pack of FIG. 1, both parts like a hinge along the edge 23 of the bottom 5 between the bottom parts 5 'are articulated.
  • the floor 5 receives the flat overall shape only after the two shell-shaped parts I and II have been connected to one another, so that the pack has a flat standing surface.
  • the base 5 does not actually have to be flat, without exception, but in a preferred embodiment it can have notch-like depressions or recesses 25 from the central edge 23 of the base 5 outwards to its respective end edge 24.
  • the two shell-shaped parts I and II are connected to one another along the edges 13 and 15 via holes or notches because, in addition to the adhesive effect, they also provide a positive connection between the two shell-shaped parts I, II.
