Definitions

  • the invention relates to a cup, in particular yogurt cup, with a container element, a separate lower part, which is formed as a stand element or panel member; and a shrink film extending at least a portion of the container member and at least a portion of the base and connecting the container member to the base.
  • yogurt cup in addition to the so-called standard cups, which are simple cup without foot, and cup with foot to use, especially the so-called cup, which have in their lower part a, usually cylindrical, preparatausformung without undercut, and the so-called cup cup, which has a conical supportiveausformung in its lower part, which tapers upwards to the bottom of the container element, so have a foot shape with undercut.
  • thermoplastics such as PE (polyethylene), PP (polypropylene) or PS (polystyrene)
  • thermoforming is cheaper and faster than injection molding, it is not used for the cup and cup cups. This is due to the shape of the foot cups and cup cups, which is more complicated than the shape of the standard footless cup due to the foot and can not be realized by thermoforming or only with excessive effort.
  • the cups and cups are only much more expensive, more elaborate and slower to produce than the standard cups, which are produced by the fast and inexpensive thermoforming, they are still produced, because the foot they have in contrast to the standard cups, increases the outer volume of the packaging, which has a positive effect on the packaging
  • Purchase decision affects can form a sidecut, which makes the feel more pleasant and makes the mug look more attractive; can increase the cup height, which has a positive effect on the purchase decision; can make sure that the cup is stable in a cup with spoon-friendly round bottom; causes no bottom depressions in the bottom of the cup are needed to gain in height; causes soil stability to increase without the need for material beads that make it difficult to remove contents such as yogurt with a spoon.

  • This panel element can increase the outer volume of the cup and form an advantageous waist of the cup.
  • This stand element thus forms the base of the cup or at least expands it. In addition, it can then increase the cup height, and it can also be a round bottom of the container element allows.
  • the container element and the lower part are separate components, they can be made with the cheapest for them each method and from the most favorable for each material.
  • the container element which has a simpler shape than the cup, preferably a non-undercut form, for example by thermoforming
  • the lower part which also has a simpler shape than the cup, for example by thermoforming, which, for example, cup-shaped Stand elements is preferred, or for example, by injection molding, which is preferred, for example, for annular lower parts are produced.
  • thermoforming which, for example, cup-shaped Stand elements is preferred, or for example, by injection molding, which is preferred, for example, for annular lower parts are produced.
  • a largely or completely undercut-free form and thus the favorable thermoforming can be used as a manufacturing method for the container element.
  • the shrink film is the connecting means for the container element and the lower part and connects them so firmly or permanently so that they are not separated from each other with proper use of the cup.
  • the cost of attaching the shrink film for connecting the container element and lower part is very low, and in sum, the proposed cup can be made cheaper and faster than a known cup or cup cup with the same shape.
  • By a preferred shrink label connection is no additional Work step required because labeling and bonding are performed in one step.
  • the proposed cup may also have at least one further container element and / or at least one further lower part and / or at least one further shrink film.
  • the materials for the container element and the lower part can be arbitrarily selected as needed and, for example, the same, but also different.

  • the container element has a round bottom.
  • a round bottom is here understood a floor whose inner surface is concave, that is bent downwards or outwards.
  • Such a round bottom is known in the food packaging industry as particularly spoon-friendly, as it allows the removal of a food, such as ice cream, yogurt, rice pudding, quark, pudding and the like, relieved with a spoon.
  • the floor can also be shaped differently as required and designed, for example, as a flat floor or as a dome floor.
  • a flat bottom is here understood a floor, the inner surface is straight or flat, and the cupola floor is understood here as a floor, the inner surface is convex, that is bent upwards or inwards and thus represents an inverted round bottom.
  • the standing element is annular or cup-shaped and / or the diaphragm element is annular.
  • annular stand element or aperture element can be produced, for example, from plastic, preferably by injection molding, whereas such a dish-shaped stand element, for example made of plastic or metal, can preferably be produced by thermoforming or deep drawing.

But it can also have another, for example, cylindrical surface if necessary.
  • the opening of the bowl-shaped stand element is preferably above, so close to the container element, but can also be down as needed. It can be located at the narrow or wide end of the conical lateral surface. Ring-shaped stand elements or aperture elements with a conical lateral surface as well as shell-shaped stand elements with a conical lateral surface whose opening lies at the far end can be stacked with minimal stacking height.

  • the shrink film protrudes radially inwardly at the lower edge of the lower part.
  • a risk of injury by the possibly sharp-edged lower edge of the lower part can be prevented or at least reduced, and on the other hand can be prevented that the shrink film unintentionally slips up and releases the lower part, so that it could come loose from the container element.
  • a, for example, annular, separate lower part gains in stability by a tight-fitting shrunk film, so that the lower part may consist of relatively thin-walled material, which advantageously reduces material and weight.
  • the proposed cup has a closure which closes the container element and contains a filling in the container element, in particular a food such as ice cream, yoghurt, rice pudding, quark, pudding and the like.

  • the molded part can, for example, completely or partially consist of a moldable hollow body, which can be changed in size by pumping up and down, in particular pneumatically or hydraulically.
  • This hollow body may consist entirely or partially of an elastic material.
  • the molding may also be variable in size by a pressing operation by compressing an elastic material wholly or in places, the size of the molding changing as a result of protrusion and retraction of the material.
  • the molded part can be changed by a variety of mechanical processes.
  • the molded part may consist, in whole or in part, of separate parts, for example, of segments or sectors and may, for example, be disassembled and assembled by sliding operations and thus be variable in size.
  • the molded part can be variable in size by rolling up and down, For example, a cuff or donut-shaped ring can be rolled into each other / bent.
  • the molding can be completely or partially covered with elastic material to obtain a desired shape.
  • the molded part does not have to describe the exact shape of the lower part / base / foot, it is sufficient, depending on the shrinkage behavior of the sleeve / shrink film, that the molded part only describes, for example, a donut-shaped ring or a relatively thin disc.
  • the shrink film conforms in such a way that a voluminous and stable foot shape is achieved.
  • a machine which carries out this method, and has corresponding features, namely: the former, which is variable in size, and a device which allows the shrinking of the sleeve, preferably through a heat tunnel.
  • the two parts are fastened to each other only slightly and are attached in particular, and the substantial support is provided by the shrinking film, shrinking tube or sleeve.
