Definitions

  • the invention relates to a stackable, thin-walled container, in particular plastic drinking cups which can be used in automatic beverage dispensers, the peripheral wall of which widens upwards at least in a range at an angle ⁇ in a plurality of successive steps, each step having a circumferential counter-conical wall section, the lower one Edge merges into a transition section forming a support shoulder in the interior of the container.
  • the invention also relates to a method for producing such containers and to a molding tool.
  • Such containers are known from DE 36 29 655 AI.
  • these cups When these cups are inserted into each other, not all of the levels of the inner cup lie on the stacking shoulders of the outer cup. Only when an axial pressure is exerted do all of the steps rest on the stack shoulders, the lower edge area of the steps that previously rested being elastically deformed. This results in axial suspension and in some cases in deformation of the cup walls, which can impair stacking safety.
  • stackable cups which have a stacking step with a counter-conical wall part in their upper part.
  • the stacking step has an annular shoulder projecting towards the inside of the container, on which the inner cup with its stacking step rests.
  • a holding part with support rings is provided below the stacking step, which are of no importance for the stacking because of their large distances from one another.
  • the transition section preferably has a flat plateau section, which preferably has an angle ⁇ 0 0 °, preferably 0-3 °, and thus runs horizontally or is inclined with respect to the horizontal. At an angle of ß> 0, the plateau section rises inwards.
  • the steps are thus in the form of an undercut, which has the advantage that the axial forces acting on the stack of containers, the Due to the inclination of the plateau sections, the plateau sections of the inner cup do not slide inwards but outwards. The individual stages can therefore not slide against each other in the axial direction, which can lead to jamming of the individual containers.
  • the larger the angle ß is chosen the easier the plateau abschmtte to move under axial load, whereby the counter-conical wall sections move towards each other, so that the support area A increases.
  • the contact area A of the plateau sections is at least one third of the width B of the plateau sections. With a large axial load and a large angle ⁇ , the plateau sections can shift so far that the entire width B of the plateau section is used as a support area.
  • the individual steps with their conical wall sections and the plateau sections are preferably designed such that when containers are inserted one into the other, all plateau sections except the upper plateau section of the inner cup rest on the plateau sections of the outer cup. With axial load, the force is immediately absorbed by all stages.
  • the advantage of the container is that due to the design of the individual stages, a high degree of stability is achieved, which also allows large axial forces to be absorbed. It is therefore possible to make the wall thickness of the containers correspondingly thin without impairing stack security. While conventional cups with a filling volume of 0.2 liters have a weight of 3.2 to 3.5 g, a cup according to the invention with the same filling volume has a weight of less than 3 g, preferably of 2.7 g. A reduction in weight is correspondingly also for smaller and larger containers with, for example, 150cc or 250cc Content possible. This results in a significant saving in material and weight.

  • the molding tool has corresponding counter-conical wall sections, which likewise have a counter-conicity angle ⁇ of more than 3 °, preferably of 3 to 6 °.
  • the horizontal wall sections of the mold are also inclined by an angle e of> 0 °, preferably 0 to 3 °.
  • air suction holes are provided in the area of the steps in the prior art, circumferential slots are made in the mold according to the invention, to which the additional vacuum is applied. In the deep-drawing process, the film to be drawn is pressed more or less into the slots in accordance with the pressures applied, so that sharp edges can form at the lower end of the steps.
  • the horizontal wall section preferably continues outwards in the lower boundary wall of the slot. There are therefore no shoulders within the mold that could hinder the formation of sharp edges at the bottom of the steps.
  • the width of the slots is preferably 2 to 5 times the wall thickness of the deep-drawn container.

If - as shown in FIG. 3b - only a floor ejector 31 is provided, this leads to damage to the lower conical wall section 6 and some steps 8d to 8f, because the upper steps 8a, 8b are still held in the tool due to the strong undercut.

Abstract

Un récipient empilable (1) à parois minces comprend plusieurs épaulements (8a à 8f). Chaque épaulement (8a à 8f) comprend une section de paroi (10) présentant un angle de conicité inversée η supérieur à 3°. Les sections de paroi (10) à conicité inversée se terminent à leur bord inférieur par une section de transition (12) et forment des rebords de support à l'intérieur du récipient. Les sections de transition (12) sont reliées aux sections de paroi à conicité inversée par des arêtes vives orientées vers l'extérieur. Les sections de transition comprennent une section plate en plateau (16) inclinée d'un angle β égal ou supérieur à zéro par rapport à l'horizontale, de sorte que la section en plateau remonte vers l'intérieur du conteneur.
