Definitions

  • the invention relates to a package for flowable filling goods with a tube formed by at least one longitudinal sealing seam, made of carrier material coated on at least one side with thermoplastic, e.g. Cardboard, at the ends of which the bottom and lid are attached, of which the lid is made of thermoplastic material without carrier material, is placed as a prefabricated, separate part by means of a flange encompassing the upper edge of the tube and is welded to the edge and has a pouring device, and the Lid has a lower surface than the outer contour, which is partially brought up to the tube edge in such a way that the lid surrounds the tube edge in the region of the partial surface in a U-shape, and the plane surrounding the pouring opening lies approximately at the height of the top edge of the tube.
  • thermoplastic e.g. Cardboard
  • the lid is formed from a separate, flat part made of thermoplastic material and welded to the edge of the tube, the edges of the lid overlapping the upper tube edge in a U-shape.
  • the cover can only be attached if the pouring device is arranged at a considerable distance from the edge of the cover.
  • the pouring device is opened and its contents are emptied, because the contents have to run onto a lower cover wall after leaving the cover and have to flow over the raised edge again at the edge.
  • Pouring of this type is unfavorable and undesirable.
  • the condition described above that the pouring device must be kept at a considerable distance from the edge of the lid, because otherwise the lid will not be properly attached to the end of the tube
  • it can be welded on because in the area of the pouring device a U-shaped gripping of the edge of the lid over the edge of the tube is impossible.
  • the object of the invention is therefore to improve a package of the type mentioned in such a way that better casting properties are made possible for lids with pouring devices with lower partial areas.
  • the pouring device is arranged on the edge of the lid without a gap.
  • the pouring device in the lid according to the invention is no longer approximately in the center, but is integrated in the lid edge at the end of the tube. Good casting properties are surprisingly achieved in this way.
  • the new cover has a flange protruding on one side on the outside, which flange can overlap the outside of the tube.
  • this is the case in addition to the partial surface section that is recessed or deep-drawn on the inside of the package, in other words where the partial surface is brought up to the edge of the tube.
  • the area of the pouring device is spared from this U-shaped gripping according to the invention, so that a direct transition from the decorative edge into the plane around the pouring device is provided. This results in the better casting properties.
  • the liquid After the liquid has left the pouring opening during pouring, it only needs to continue to flow through the plane surrounding this opening in order to reach a pouring edge lying at the outermost edge, from which the stream breaks off and form a liquid jet in the desired, ideal manner can. Otherwise, the favorable shape of the lid edge is used to apply pressure and counterpressure when welding the lid onto the tube edge.
  • the teaching according to the invention suggests how good welding and sealing between the lid and the tube at the edge of the tube is still possible: one also uses when welding the lid the tension in the paper tube.
  • This exploitation is particularly advantageous for the counter forces of the welding jaw if, in a further embodiment of the invention, the cover has at least three corners and the pouring device lies in one of these corners, where the edge has a high curvature.
  • the top view is preferably configured to be quadrangular, and the pouring device lies in a corner of a quadrangle. The angle here is about 90 ° and thus creates a not inconsiderable tensile stress in the paper. This is sufficient to support a strong counterforce when welding jaws are pressed onto the lid from the outside in the direction of the outer tube surface.
  • the tube of the pack forms the side faces and consists of paper coated on both sides with thermoplastic.
  • a bottom (not shown) is attached, which can be, for example, square and is formed from the folded tube of the pack as a folding closure and has a transverse sealing seam with triangular flaps folded over onto an adjacent wall.
  • the cover 2 is triangular in plan view, with two edges running along the upper edges of the two flat side surfaces and the third line of the triangle connecting these two sides running across the diagonal, if one looks at the package, which is square in cross-section below and above, from above .
  • the package which is square in cross-section below and above, from above .
  • there is a recess in area 3 of the pack (FIGS. 1 and 4) such that the volume of the pack tapers upwards.
  • a handle 4 is attached in the cut-off volume area.
  • the lid 2 is of particular importance for the invention. It is a prefabricated, separate part made of thermoplastic material without carrier material. On the outer circumference, the cover 2 has a flange 5 which projects on one side and engages around the upper edge or the upper edge 6 of the tube 1.
  • the lid 2 also has a lower-lying partial surface 21, which is drawn or countersunk in relation to that plane 22 in the direction of the interior of the package, which surrounds the pouring opening 7 of the pouring device, generally designated 8.
  • the lower-lying partial surface 21 is designed to be as large as possible and surrounds the pouring device 8 on all sides as far as possible except for the front pouring tip 9, so that the U-shaped encompassing of the thermoplastic lid material around the tube edge 6 largely even around the pouring device 8 has moved around.
  • the other embodiment according to FIG. 4 is also conceivable, in which the lower-lying partial surface 21 has an approximately trapezoidal shape without reaching closer to the pouring opening 7 or even encompassing it on three sides. It has been shown in tests that the tensile stress in the paper material of the tube 1 is sufficient to provide good support for the pressure of the welding jaw from outside to inside in the region of the pouring device.
