Definitions

  • the invention relates to a canister according to the preambles of claim 1 and claim 8 and a method for producing the canister according to the preamble of claim 10.
  • a canister according to the type mentioned in the preamble of claim 1 is already known, in which the fold lines are formed by bead-like ribs which run on the one hand along the main median plane of the canister and on the other hand in one half transversely to the main median plane about a quarter or three fourths of the height of the canister.
  • the bead-like, rib-shaped fold lines are difficult to achieve in terms of production technology and impair the appearance of the canister because they protrude beyond the surfaces and make labeling and decorating difficult on the broad side.
  • the canister is difficult to fold, since the bead-like, rib-shaped folding lines only make the folding process to a limited extent, at best in the initial phase and more difficult in the final phase.
  • a canister of the type mentioned in the preamble of claim 8 is known from EP-PS 0 274 742. It is disadvantageous that residues of the contents remain in the blown-out hollow handle part, which is undesirable. In order to avoid these disadvantages, it is known from DE-OS 37 22 691 to no longer design the handle part as hollow, but with a full, double-T-shaped cross section. Such a grip part has a relatively sharp-edged profile, which complicates the handling of the canister.
  • the object of the invention is to form a canister of the type mentioned so that the disadvantages mentioned are avoided.
  • the fold lines of the foldable canister are designed as beads not only results in an appealing exterior of the canister, but above all it also makes folding easier, since the beads do not hinder the folding, but instead support this process.
  • the folding is further facilitated by the middle fold line, which is located approximately halfway up the canister.
  • the canister prefferably has an oval or polygonal cross section.
  • An embodiment according to claim 4 is particularly advantageous Corners also give the container a particularly good stability, which is further supported by a concave curvature of the flattened corners, so that the canister can be made with a very small wall thickness despite the foldability, which in turn leads to material savings.
  • the stability and in particular the labeling and decorability of the canister can be improved according to claim 5.
  • the canister When the canister is designed according to claim 8, squeezing the ends of the hollow handle part together ensures that the contents of the canister cannot get into the handle part and thus no residues form when emptied. Nevertheless, the grip part is hollow in the area between the bruises and therefore has a rounded cross section, which makes handling easier. It is particularly useful if the canister is designed according to claim 9, whereby the stackability of such canisters is known to be easier.
  • the manufacture of the canister is preferably carried out according to claim 10, in that a vacuum is applied to the blow mold for the handle part in the usual blowing process for the manufacture of the canister, whereby the hollow handle part is formed.
  • the canister according to the invention is characterized by an optimal shape, which enables sufficient strength properties of the canister despite the reduction in the use of raw materials in the manufacture.
  • the canister can be used as a single-use or reusable container and, if necessary, can be disposed of inexpensively by folding and the associated volume reduction.
  • the figures show a canister with a foot part 2, a head part 4 and an intermediate wall part 6.
  • the canister has a rectangular cross section with flattened corners 8, which is shown in FIG Way are concave.
  • the wall part 6 is at least slightly set back relative to the foot part 2 and head part 4.
  • the walls 10 contain bead-shaped folding lines 12, 14, 16 which extend in one half of the canister from the main median plane 18 over the corners 8 to the wall 20 of the broad side of the canister.
  • the middle bead-shaped fold line 12 is arranged approximately halfway up the canister.
  • the lower fold line 14 and the upper fold line 16 are each at a distance from the top and the bottom of the canister which corresponds to approximately half the width of the canister.
  • On the side of the canister opposite the middle folding line 12 there is a further analog folding line 17, indicated by dash-dotted lines, which enables the canister to be folded in a Z-shape (see FIG. 6).
  • the canister contains on its head part a recessed grip 22 with a hollow grip part 24.
  • the filler neck 26 is arranged in the recessed grip 22.
  • the foot part 22 contains a recess 32 into which the parts of the handle part 24 and the filler neck 26 projecting beyond the stacking surface 28 can engage.
  • Figures 4 to 6 show different stages of folding the canister.
  • the canister By pressing in the canister on the wide side at the level of the middle folding lines 12, the canister is bent, as can be seen from FIG. Then the foot part 2 and the head part 4 can be folded against one another, so that the folding configuration shown in FIG. 5 results. This reduces the original volume of the canister by up to 85%.
  • FIG. 5 The folding configuration of Figure 5 is relatively large. Should it be desirable to obtain a small-area folding body, the folding body of FIG. 5 can be folded back again, as can be seen from FIG. 6, whereupon the foot part and the head part are practically parallel one above the other and the middle wall part is folded in a Z-shape.
  • the grip part 24 is hollow and squeezed together at its two ends facing the canister, so that at these pinch points 34, 36 there is a medium-tight seal with respect to the interior of the canister.
  • Suitable for producing the handle part 24 is the blow tool 38 shown in dash-dot lines in FIG on the wall of the mold recess 42.
  • the canister can be made from the usual materials such as polyethylene, polypropylene and so on, which are either recyclable and / or environmentally friendly.
  • the can shape can be made particularly light by the present design, so that considerable material savings result.
