Definitions

  • the invention relates first of all to a bottle-shaped box, e.g. made of plastic with partitions.
  • Known bottle crates of this type are used for setting and transporting bottles, in particular beverage bottles.
  • efforts are underway to no longer sell drinks in bottles or cans, but in plastic bags.
  • Milk for example, has been offered in such plastic bags for some time. These bags filled with milk are offered to the customers for sale more or less lying on top of each other on the shelves of the sales outlets. This presentation is not appealing.
  • the transport of filled bags of this type is also not optimal.
  • the foil of the bags should not be too thick because of the disposal, but it cannot be too thin because of the stability.
  • the known milk bags are also difficult to present standing when they can be supported on a wall, the outer skin of the bag is wrinkled and the inscription on the bag is difficult to read, if at all.
  • the object of the invention is first of all to be able to present and transport such bags filled with liquid better.
  • the liquid-filled bags are placed in a plastic bottle-shaped box with compartment walls, this box at the bottom of the compartment having a protruding projection into the compartment, which on the shell of a attacking part of the liquid in the bag displaced into the compartment and filled with liquid.
  • the protrusion presses in a little bit.
  • This slightly increases the pressure in the bag the liquid displacement is reduced by reducing the gas bubble in the bag, e.g. Air bubble balanced.
  • This reduction in the volume of the bag through this projection and the resulting increase in pressure within the bag causes the bag to look like a bulging bag and that the bag becomes stiff in itself and therefore also has a smooth surface, which is when Placing the bag on its base does not fold.
  • the geometry (length, width, height, radii) of the displacement projection can be adapted to the respective bag and in particular to the size of the gas bubble present in the bag.
  • the protrusion can be like a small quill (round or square spigot) or e.g. be formed like the raise in an egg carton. Even small protrusions of this type make the bag appear full and the bag is stiffened in such a way that it can be held securely even by a low compartment.
  • the displacement projection can also be designed such that there is still a space below its highest point, into which the lower tips of a bag filled with liquid can enter.
  • the foil bags consist of a tube section made of plastic foil, which is closed at one end by a straight seam.
  • the empty foil pouch when placed on a flat surface, has an approximately rectangular shape. If the foil pouch is filled, the bottom end of the foil pouch does not have a round cross-section because of this straight seam, but rather extends at an acute angle seen transversely to the longitudinal direction of the pouch, the apex of the angle being formed by the seam and the lower corners of the filled one Bag taper a little, for example, if you look at the bag hanging at its upper end.
  • this part of the bag bulges around the highest point of the displacement projection and the adjacent parts of the bag bottom, in particular the two outer tips move in Towards each other.
  • This movement should be possible in the aforementioned embodiments of the invention, possibly even favored.
  • the optimal shape of the displacement projection can also depend on the content of the film bag, for example, a different shape of the displacement projection can be preferred in the case of cored filling material than in the case of a film bag filled with a liquid.
  • the protrusion may be provided anywhere in the compartment in the box. It is expedient to attach it to the shelf, for example on the edge of the shelf, for example by means of a ring, or in the middle of the shelf, where it is frustoconical in embodiments of the invention.
  • such truncated cones can have a base area that is about 1/16 of the shelf and the upper diameter of the displacement projection corresponds to about half the radius of the base.
  • the height of the projection can be about 70 to 80% of the average height of the compartment wall. With this geometry of the projection, tubular bags for 1 liter of milk can be presented quite well.
  • the box has quills which are connected to one another in the longitudinal direction of the box by compartment walls. Also, in embodiments of the invention, the quills can be about twice as high as the compartment walls that delimit the bag placed in the compartment.
  • the individual compartments that are adjacent to one another can remain open parallel to the narrow side of the box.
  • the box walls can be so high that the filled bags placed in the compartments do not protrude above the upper edge of the box walls. Then the individual boxes can be stacked on top of each other just like bottle boxes.
  • the box side walls are not as high as the bags placed in the box; for the entire container in which these filled tubular bags are transported but also presented, the tubular bags set in this box are higher than the edges of the box.
  • a box similar to the lower box can be placed with its opening facing down over the lower box.
  • the end faces of two opposing box walls of the upper and lower boxes can rest on one another, so that the upper box is thereby supported on the lower box. Also, at least sections of the upper end faces of the sleeves of the lower and the upper box can lie one on top of the other, so that the upper box is also supported on the lower box.
  • the upper box is releasably attachable to the lower box, so that the upper box can be removed after the filled bags have been transported. The customer can then take the filled bag out of the lower box from above in the sales outlet.
  • the edge of at least one side wall of at least one of the two boxes runs unevenly and, when the upper box is attached, this edge delimits a viewing window through which the contents of this box can be identified.
  • the lowest edge portion of the side walls is higher than its compartment walls.
  • the lowest edge section can also be higher than the projection.
  • the height of a compartment can be approximately 1/4 to 1/2 the height of the set bags.
  • the box bottom of the upper box has no protrusions.
  • the container (box) can also consist of cardboard or paper mache.
  • the invention also relates to a bag made of plastic film for holding liquid, which is suitable for insertion into the aforementioned box. Efforts are no longer being made to sell drinks in bottles or cans or cardboard packaging, but rather in plastic bags. Milk, for example, has been offered in such plastic bags for some time. These bags filled with milk are more or less lying on top of each other on the shelves of the sales outlets and offered to customers for sale. This presentation is not appealing.
  • the known plastic bags used for this purpose consist of a tubular section made of plastic film, which has at its lower edge a seam that runs straight in the flat empty bag, for example adhesive seam or weld seam.
  • a hose section can also be produced in that a film section is folded once and welded or glued on its long sides. In this case, there is no seam at the lower end of the bag, but only an edge on which the plastic film is folded over by 180.
  • foil bags filled with liquid, for example milk which are placed in such a bottle-like container with a displacement body on the bottom of the box, the lower end of the bag winds around the displacement body. The distance of the corners of the The lower seam of such a bag decreases to the extent that the displacer bulges the seam upwards.
  • the corners are lower than the bottom section, which sits on top of the sinker. In the space above the box bottom next to the displacement body, the corners or tips at the lower end of the bag therefore move towards one another after it has been seated on the displacement body. This occurs regardless of the height of the sinker. If the displacement body is too high, there is too much weight of the bag on the bottom portion of the bag which sits on top of the displacement body. If it is too low, a large section of the bag bottom rests on the bottom of the container and the movement of the corners towards one another counteracts the friction on the bottom of the container, so that the tendency of the film to expand in the area of the displacement bodies increases.
  • the further invention is based on the object to get a better grip on these problems.
  • This object is achieved according to the further invention in that when using a bag made of plastic film in an upright position in a container similar to a bottle crate with displacers on the bottom of the container, the corners of the lower edge, seen on a flat empty bag, are arranged higher than the center of the edge are.
  • the lower corners of the bag and their adjacent parts can sink less far downward than the bearing surface of the bag on the upper surface of the displacement body, and the aforementioned problems can be solved more easily. If the course of the upper edge of the bag is influenced by the lowering of the lower corners of the bag, the lower region of the bag and / or a horizontal inscription on the bag is distorted less or not at all when the lowering is less.
  • the rounded bottom makes it easier to insert the bags because the corners do not interfere with this movement.
  • the emphasized corners in the upper area form a better starting point for holding and for cutting open the bags.
  • the emphasized upper corners make it easier to clamp the bags in a suitable container so that a partially emptied bag cannot collapse.
  • the lower edge of the bag can be concave in the form of a circular arc segment.
  • the lower edge of the bag deviates from an arcuate line. It is only important that the center of the lower edge of the bag is located lower than its corners, e.g. a bulge projecting downwards can be provided in the middle of the lower edge of the bag.
  • the invention can be implemented in foil bags which are tied at the top, but it can also be implemented in other embodiments which, when filled, have a glued or welded seam at their upper end which runs in a straight line.
  • the upper edge of the bag does not run straight, but the upper corners of the bag edge are arranged higher than its center. If, therefore, the lower corners of the edge of the bag sink down into the space next to the displacer, the upper corners of the edge of the bag also move somewhat downwards.
  • the inscription on the bag can be arranged so that it takes into account the lowering movement of the lower corners and the following movement of the upper corners in a certain shape of the displacer in the container and therefore in the presentation of the filled film bags in the container mentioned approximately horizontally Direction runs.
  • the upper edge of the film bag has the same shape as its lower edge. Then the tube sections, the lower end of which is then welded shut, can be cut off from a longer film tube without waste.
  • the course of the upper edge of the foil bag can be provided differently from the course of the lower edge in embodiments of the invention.
  • the bag bottom can have a reinforcement in the area of the support surface on the displacement body, so that the displacement body does not damage the film and the liquid runs out of the bag even when subjected to strong vibrations when a container with filled plastic bags is transported.
  • a box which can be made of plastic, but also of cardboard, has outer longitudinal side walls 1 and 2 and narrow side walls 3 and 4, which, in the embodiment shown, have the undulated profiles shown in FIG. 1 and have inwardly directed shafts 5 on the long side walls and shafts 6 on the narrow side walls.
  • the side walls can have a flange 27 with reinforcements 28 directed downwards, which form a handle with the flange 27.
  • the box-like container shown in FIGS. 1 and 2 has twelve compartments 8, which are divided into three rows arranged next to each other, each with four compartments. At the intersection of four compartments there are quills 10, which are firmly connected to a container bottom 9 and protrude the upper edges 11 of the longitudinal side walls 1 and 2 by approximately 1/3 of their height.
  • each compartment 8 a frustoconical projection 12 is arranged on the box bottom 9, which in the illustrated embodiment of the invention does not quite reach the height of low sections of compartment walls 13 with which adjacent quills 10 are connected to one another in the longitudinal direction of the container.
  • These compartment walls 13 separate two compartments 8 arranged parallel to container walls 3 and 4, whereas compartments 8 adjacent to one another in the longitudinal direction have no dividing walls.
  • the projection 12 If a tubular bag with a liquid is placed in a compartment 8, the projection 12 is enclosed by the lower end of a tubular bag 14 due to the gravity of the liquid, the projection 12 presses in the envelope of the tubular bag 14 and thereby displaces liquid, so that the pressure in the tubular pouch increases by reducing the volume of the air bubble.
  • the sleeves 10 also have an approximately frustoconical shape. This design of the sleeves 10 and the projections 12 means that the cross section of a compartment 8 on the container bottom 9 is somewhat smaller than this cross section at a distance from the bottom 9.
  • feet 15 On the underside of the container bottom 9 there are also feet 15 which are helpful when stacking on top of one another.
  • a container 16 corresponding to the container 7 explained above can, in one embodiment of the invention, be placed with its opening down over the lower container 7. End faces of two opposite container walls 3 and 4 of the upper and lower containers and the flanges are supported on one another. Further supports can be formed in embodiments of the invention by the end faces of the sleeves 10 of the lower and the upper box lying on one another, as is shown in FIG. 2. It is not necessary that the upper surfaces of the quills 10 are flat, they can be curved as well and still provide support for the upper container.
  • the upper container 16 has no projections 12. Its edge is curved in a manner similar to the edge 11 of the longitudinal side walls of the lower container 7.
  • the upper container 16 is releasably attached to the lower container 7 by a device 18.
  • a device 19 can also be provided on the side opposite the device 18, which also connects the two containers 7 and 16 to one another.
  • the upper container 16 also has compartment walls 20 at those locations where compartment walls 13 are provided in the lower container 7 and it is otherwise essentially the same as the lower container 7, but, as mentioned, without the projections 12.
  • the container 16 has at its bottom in FIG. 2 upward facing 22 the feet 15 corresponding recesses 21, so that on the bottom 22 of the container 16 placed over the container 7 another container consisting of two stacked containers 7 and 16 can be stacked.
  • the individual compartments 8 can be designed differently, in particular a completely different cross section, for example a rectangular cross section sen. It is only essential that there is a projection 12 which presses in the envelope of the set bags and thus tightens this envelope.
  • the bags placed in these containers can be transported safely since, with the exception of the recess 23 delimited by the edges 11 and 17, they are completely enclosed.
  • This recess 23 can also be designed as desired.
  • the bottom 22 of the upper container 16 can have openings 25 in the area of the compartments 8 and the upper end of the projections 12 have an opening 26 so that undesired liquid cannot accumulate in the containers 7 and 16 when these containers are compared to FIG Stand upside down, that is, swapped up and down.
  • the displacement projection shown in FIG. 2 is, for example, conical. However, as FIG. 3 shows, it can also be cylindrical. 3 shows such a displacement projection 30, which has a flat surface 31 at the top.
  • the displacement projection 32 shown in FIG. 4 is closed at the top with a hemispherical wall.
  • These displacement projections can also have an opening 26 shown at the top in FIG. 2.
  • the projections are wedge-shaped.
  • the projection 34 in FIG. 5 can extend over the entire width of the compartment or can also be arranged only in the middle of the compartment bottom.

  • the displacement projection 36 in FIG. 7 differs from the displacement projection 34 in FIG. 5 only in that the upper end of the wedge is not straight, but curved.
  • the displacement projection 37 according to FIG. 8 differs from the displacement projection 35 in FIG. 6. If the displacement projection 34 is only in the middle of the shelf 9 of a compartment and this projection does not extend from one compartment wall to the other, then in the Cavity 38 below the wedge the tips of the filled foil bag enter when the foil bag is placed on the displacement body so that its lower closure seam runs parallel to the upper curve of the displacement projection 34. The same applies to a greater extent to the embodiments according to FIGS. 6 and 8.
  • the displacement projection In the embodiments of the displacement projection shown in FIGS. 12 to 15, these have two plates which are arranged at a distance from one another and in the center of the compartment and are of identical design.
  • the displacement projection has two rectangular walls 44 and 45 arranged at a distance from one another. The lower end of the plastic bag is immersed in the space 46.
  • the walls 44 and 45 can extend over the entire width of the compartment, that is to say from compartment wall to compartment wall, or can only be provided in the middle of the compartment floor 9.
  • the displacement projection 47 according to FIG. 13 differs from the displacement projection according to FIG. 12 only in that the plates 48 and 49 are rounded at their upper end.
  • the displacement projection 50 according to FIG. 14 differs from the displacement projection 47 only in that the lateral edges 64 of the plates 50, 51 run obliquely upwards, ie conically.
  • the displacement projection 52 has the same conical shape, but the upper edges 55 of the plates 53 and 54 are straight. 12 to 15 show the displacement projections in the diagram.
  • FIG. 16 shows an embodiment of a displacement body 56, which is open at the top and tapers downwards to a cone shape and has a passage 57 at its lower end.
  • the tips of a filled plastic bag, which is placed on this displacement projection, can move towards each other and thereby enter the space 58, which is formed in that the radius of the conical wall of the projection 56 below is smaller than the radius at the upper end of the displacement projection 56.
  • a displacement projection 59 which has a pin 60 fastened on the shelf 9, which carries a ball 61 at its upper end, acts in a similar manner.
  • the lower tips of the filled foil bag can move downwards and to each other depending on the contents so that their distance is smaller than the diameter of the ball 61, so the tips come into contact with the pin 60.
