Definitions

  • the invention relates to a plastic container according to the preamble of independent claim 1.
  • Plastic containers of this type such as those used in the household for periodically metered dispensing of liquid or powder detergents, must be disposed of after they have been completely emptied.
  • the disposal which generally takes place in the household waste container, waste collecting bucket and garbage truck, requires very large volumes with regard to the plastic mass to be disposed of effectively, since most of these plastic containers are dimensionally stable for practical dosing and thus also their original volume when empty maintained.
  • European patent application No. 0 408 929 describes a foldable plastic bottle, the bottom part of which has an inwardly directed V-shaped indentation with a bottom folding edge. This arrangement makes it easier the foldability of the empty bottle is at the expense of stability, which is of crucial importance for pourable contents.
  • the container shown in FIGS. 1 to 3 which can be produced, for example, by blowing from a thermoplastic, has a hollow cylindrical middle part 1, to which a pouring section 2 is connected at the top and a bottom section 3 is connected at the bottom. Both the pouring section 2 and the bottom section 3 are from cylindrical middle part 1 is offset by a circular fold line 4 or 5.
  • the two fold lines 4 and 5 are connected to one another by longitudinal fold lines 6 and 7. The latter extend from the lower fold line 5 beyond the upper fold line 4 to the upper edge of the pouring section 2, the extensions thereof in the pouring section 2 being designated 6a and 7a in the drawing.
  • two additional folding lines 8 and 9 are provided on the pouring section, each of which runs above the circular folding line 4 from one of the longitudinal folding lines 6 to the other 7 and preferably has an elliptical shape. Due to the mutual offset of the two longitudinal folding lines 6 and 7, the two additional folding lines 8 and 9 have different lengths.
  • a further auxiliary folding line 10 extends from the central region of the shorter additional folding line 8 up to the edge of the pouring section.
  • the pouring section 2 can be pressed and folded by light finger pressure on the two locations designated B - or also on the location C below, as indicated by the arrow P1 in FIG. 4.
  • a lid 12 also located on the upper opening 11 of the container is repelled by the deformation of the opening 11.
  • the empty container is disposed of as follows:
  • the pouring section 2 is brought to collapse by pressure on the points B or C (FIG. 2) and folded in the direction of the arrow P1 (FIG. 4), whereupon the central part 1 is flattened by lateral pressure in the region of the longitudinal fold lines 6 and 7 becomes. Thanks to the described configuration of the fold lines, the pouring section 2 will then bear against the flattened central part 1 under the influence of an elastic prestress. Now the bottom part 3 is folded over and pressed against the flat middle part 1 according to arrow P2. The entire container is thus reduced to a minimum volume and maintains this volume during its disposal.
  • All fold lines can be groove-like depressions projecting inwards from the peripheral surface of the container, the container wall thickness in the groove region being unchanged. According to a preferred embodiment, however, the container wall thickness is reduced at the bottom of the groove in order to facilitate the collapse of the container. 5 shows the reduction in wall thickness at the point N using the example of the fold line 7. It can also be seen from this figure that the grooves forming the fold lines are preferably sharp-edged, that is to say not rounded, at the base of the groove.
  • the idea of the invention can be realized both on circular cylindrical and on differently shaped, for example cuboid, containers.
  • the circumferential folding lines (4, 5) are then not circular, but form a closed rectangle or square.
