Definitions

  • the invention relates to a package for flowable fillings with a tube formed by at least one longitudinal sealing seam, at the ends of which the bottom and lid are attached, of which the lid consists of thermoplastic material without carrier material, is molded onto the tube and has a pouring device, the tube from at least one side with a thermoplastic coated substrate, e.g. Cardboard exists, the bottom is square and is formed from the folded tube of the pack as a folding closure and a handle connected to the lid is attached to the side of the tube and below the lid.
  • a thermoplastic coated substrate e.g. Cardboard exists
  • liquid packs Of the large number of liquid packs, those are known which are formed from a flat, coated cardboard web into a tube, filled and provided with a bottom and a lid.
  • larger packages for example for the transport of drinking water.
  • the pack manufacturers have made various considerations as to how the cheapest and cheapest way to attach a handle to a plastic packaging of the type described above.
  • One of the considerations is that a part of the tube wall adjoining the circumference of the lid is folded onto itself to form the handle and connected to form a double-walled surface in which the gripping opening is provided.
  • the manufacturer could create such a pack from a flat sheet, while the other advantages of known packs could also be retained, for example good opening of an otherwise tight pouring device, reclosing of the same, etc.
  • the double-walled surface with the gripping opening could, according to the above-mentioned packing, be configured triangularly in such a way that its upper edge forms a short catheter, its outer folding edge running approximately in the longitudinal direction of the tube forms a long cathete and the two inner folding edges lying one on top of the other form the hypotenuse.
  • This area could best be made triangular, with each half of this double-walled area also being triangular. This results in a good grip with a tough grip.
  • Such a pack would have the disadvantage, however, that apart from a special, unavoidable cut of the shape at the bottom and lid of the pack, there would be a fold for the triangular surface mentioned, which would offer a relatively large dead space for the overall pack.
  • Such a package could only be stacked, stored and transported with a large amount of dead space when relatively large volumes were used.
  • the pack manufacturer is aware, however, that the costs of transporting and storing liquid packs play such a significant role that further considerations have been made with the aim of further improving the pack described above.
  • the outer dimension of the base to form a cuboid outer contour of the pack is equal to the square cross-sectional dimension of the pack from the bottom to the lid and that the handle is molded together with the lid within the cuboid outer contour of the pack.
  • a suitable pouring device which is also known per se, can be attached by injecting the lid. This provides the end user with a liquid pack that has largely achieved all of the desirable properties.
  • such a double-walled triangular field of this kind is cut off from the coated cardboard web in the pack according to the invention, for example where the gripping opening of the handle begins at the pack discussed at the beginning.
  • the folding can be done differently in such a way that in the lower area up to the middle area the package remains cuboid and only in the upper area is a tetrahedral or pyramid-shaped space cut or removed, in which the molded handle is accommodated .
  • the package according to the invention can be packed face to face without the expensive dead space.
  • the handle is located in a tetrahedral space, one edge of which is formed by the diagonal of the cover.
  • the tetrahedron is a triangular pyramid. It therefore has triangular tetrahedral surfaces, and the one edge of the one surface lies in the preferred embodiment just described in the diagonal of the cover.
  • This diagonal is expediently between those two corners of the rectangular or square cover at which the pouring device is not provided.
  • a straight line runs from the center of this diagonal to the pouring device or pouring tip of the lid perpendicular to the diagonal mentioned.
  • the handle When viewed from above on the lid, the handle then also runs perpendicular to this diagonal, but away from the pouring device to the other side of the diagonal.
  • the pack can be produced particularly easily in this way because the diagonal also results in favorable folds.
  • the tetrahedron surface passing through the diagonal of the cover intersects the rear longitudinal edge of the tube in a lower corner point, which is 1/3 to at a distance from the cover 1/2 the height of the pack.
  • the inclination of the molded handle to the cover or to the longitudinal axis of the tube can be selected and adjusted in this way. It is useful if the handle is as close as possible to the center of gravity of the pack. This is achieved if the handle can be positioned more towards the center of the pack. This has practical reasons for use by the end user. If the latter has opened the package, the package should be as vertical as possible when the package is lifted using the handle according to the invention, so that good is not undesirably poured out too early at the start of pouring.
  • the measures according to the invention also have the further advantage that an inexpensive folding can be provided and thus less paper or cardboard is used.
  • a double-walled base strip made of coated cardboard is provided, starting from the lower corner point and running in the direction of the longitudinal axis of the tube to the cover.
  • the handle can be firmly anchored to the cardboard material in the area of this tetrahedral surface over the entire height of the tetrahedral surface on the diagonal. Even with larger liquid packs, the handle can no longer be removed from the pack during normal use. All forces introduced into the handle by the weight of the filled package are evenly distributed.
  • the. double-walled base strips are shorter than the height of the triangular tetrahedral surface on the diagonal and only part of the tetrahedral surface consists of coated cardboard. From the upper, cover-side end of the double-walled base strip up to the diagonal and to the side of this line up to the ends of the diagonal, this results in a triangular surface which, according to the inventors' ideas, should consist of plastic and preferably two se with particular advantage should be molded onto the cardboard material together with the handle and the lid.
  • One advantage achieved in this way is the avoidance of the cut of the shape already described above.
  • a lifting handle is attached in the area of the lower corner point. Its attachment allows a position for the main handle in such a way that the pack is predominantly vertical before the first pouring of the filling material, so that sponging is avoided. Nevertheless, the end user can use only one hand to tip this pack out of the vertical with the least effort, for example because a single finger of the hand is placed in the lifting handle and is sufficient to produce the horizontal component.
  • This lifting handle makes pouring particularly pleasant and simplified.
  • the upper edge of the handle fastened to the lid is rounded from the rear longitudinal edge of the tube upwards to the lid and forwardly to the pouring device and merges into at least one partial surface of the lid.
  • the finished pack for liquids shown in FIGS. 1 to 4 consists of the tube, designated overall by 1, which forms the four side walls, which are designated in particular by la, lb, lc and ld in FIG. It can be seen that only the two side walls la and ld are rectangular, while the side walls lb and lc are trapezoidal.
  • the four side walls la - ld are formed over the longitudinal sealing seam 2 to the tube 1.
  • the floor is formed in a manner known per se by those wall panels which are shown in the blank in FIG. 8 below.
  • the area of the lid 4 is important and interesting for the explanation of the invention.
  • the lid 4 is provided with the pouring device 5, which is shown somewhat more precisely with reference to FIGS. 5 and 6, and in the rear area with the handle 6. It can be seen how the handle 6 is completely arranged within the cuboid outer contour of the pack. It is located practically in a tetrahedral space between the diagonal D of the cover 4 and the upper cut-off area of the rear longitudinal edge 7 above the lower corner point P. Seen from above in a top view of the cover 4 (FIG. 4), the outer dimension a can be seen. a (FIG. 1) of the bottom 3.
  • this square is the square cross-sectional dimension of the pack. This extends from the bottom 3 of the pack to the lid 4 over the entire height H of the pack.
  • the outer contour of the pack is also determined by the height dimension H ( Figure 2). Since the handle 6 is located entirely within the outer contour of the pack, the upper part of the handle 6 does not protrude above the pack in the illustration in FIG. 2 (size H).
  • the outer contour of the pack is practically formed by the cuboid, which results from the product of the two side lengths, a and the height H, the volume of which is equal to a-a-H.
  • the handle is shown as being arranged in a tetrahedral space as described above.
  • the lower corner point P can be arranged at a distance d (FIG. 2) from the cover 4, which is equal to 1/3 to 1/2 the height H of the pack.
  • the handle 6 does not have to start from a diagonal D as shown in FIG. 1, but can also be further forward or further back.
  • the space in which the handle 6 is located within the outer contour of the package can also start from a line in the lid 4 which lies in front of the diagonal D, i.e. within the triangle, which is formed by the two side edges a next to the pouring tip and the diagonal D.
  • Another other embodiment could also have the handle in a space that is smaller than the space from the lower corner point P to the diagonal D.
  • the handle 6 should be located substantially near and above the center of gravity of the filled package.
  • This dashed line is the upper edge of this double-walled base strip 9, which lies completely in the handle 6 and does not protrude into the gripping opening 10.
  • the lower web of the handle 6 between the gripping opening 10 and the tetrahedral surface F can be attached to this double-walled base strip 9 in a particularly favorable manner.
  • Cover 4 with handle 6 can be welded or injection-molded onto base strip 9, for example, in the manufacture of the pack, when the top end of tube 1 is closed.
  • the double-walled base strip 9 is formed from the coated cardboard material, it extends from the lower corner point P inwards and upwards to the cover 4, but does not reach the cover 4 but ends beforehand at the intersection of the two lines 11 and 12, so that it shorter than the height h (only shown in the other embodiment of FIG. 7) of the tetrahedral surface F on the diagonal D. Consequently, only part of the tetrahedral surface F consists of coated cardboard, namely that part which is formed by the side edges S1, S2, 11 and 12. The other surface f, which is even outside the plane of the tetrahedral surface F, consists only of plastic without a box.
  • FIG. 7 shows another embodiment of the invention, in which a lifting handle is arranged in the area of the lower corner point P, namely in the case of a 2 l liquid pack, at a small distance of 2 to 4 cm, preferably with the handle 6 in one piece on the rear Longitudinal edge 7 is molded.
  • the end user can, for example, insert one to three fingers into the gripping opening 10 of the handle 6 in order to lift the package for dispensing, and engage with the finger 13 in the lifting handle 13 in order to control the tilting movement more precisely.
  • the pouring device shown in more detail in FIGS. 5 and 6 and generally designated 5 consists of a lid 14 of elongated shape, on the top of which a handle 15 is molded.
  • a handle 15 On the lower side opposite the handle 15, an all-round flange 16 is formed on the lid 14 towards the inside of the pack, which has an undercut 17 over a wedge-shaped collar 18.
  • the lower edge 19 of this collar 18 protrudes into the interior of the package, and the entire pouring device (except for the handle 15, which is folded over in the transport configuration) is located in a depression designated by 19, which is characterized by ramp-shaped inclined surfaces 20 and 21 (everything Plastic) is formed. These ramp-shaped inclined surfaces then merge into the general upper wall of the cover 4, designated 22 in FIG.
  • a line of weakness is provided around the collar 16, along which at first opening of the lid 14 can be torn out of the lid surface 21.
  • the cover 14 is articulated via a band 24 as a hinge. This runs above the wall 25 (FIG. 5), whereby a space 26 is formed which is open under the band 24 on both sides.
  • a first plane E 1 is defined by the weakening line 23 approximately halfway up the collar 16, which lies at a distance a '(FIG. 6) from the main plane E 2, which passes through the surface of the cover 4 or its surface Wall 22 is formed.
  • the surface 27 of the tearable closure cap 14 of the pouring device 15 lies in a third plane E3, which lies between the lower plane E1 and the upper plane E2. If, after the cover is molded onto the tube 1, the handle 15 is folded horizontally, the space between the third surface E3 and the upper level E2 is sufficient to accommodate the entire wall thickness of the handle 15. In this folded shape ( Transport shape), in which, for example, the cover 4 can be formed, all parts that are formed together with the cover are located in one piece within the outer contour of the overall package.
  • a double-walled base strip 9 is arranged in the handle area, the upper edge of which is shown by the dashed line in FIG. 2 and the lower edge of which is in the projection of line S1, the handle 6 can also be in the lower quarter, in lower third or in the lower half of the coated cardboard alone, while the rest of the handle 6 is made of plastic without a carrier material.
  • the middle part can also consist of a combination of plastic and coated cardboard, and the lower part can only be constructed from the normally coated cardboard.
  • a plastic strip should also be formed not only on the outside but also inside the pack from top to bottom approximately up to the region of the lifting handle 13.
  • the plastic strip can also over the area or the height of the H ebegriffes addition to 13 after extending molded to the floor below are.
