Definitions

  • the invention relates to a cup-shaped packaging container made of at least one plastic material, a closure lid for a cup-shaped packaging container, a packaging unit and a method for closing a packaging unit, according to the features in the preambles of claims 1, 2, 3 and 30.
  • the invention further relates to a closure device made of plastic for a container formed with an edge bead and a container formed therewith, corresponding to the features in the preambles of claims 33 and 49.
  • a closure device in the form of a lid which extends over the edge of the container.
  • a closure device in the form of a lid which extends over the edge of the container.
  • the lid By one in the frame or Formed edge of the lid locking edge, it is possible to connect the lid by snapping to an edge bead of the container and to close it in this way.
  • the lid can also serve to close the container again if the sealing film or the sealing film has first been removed and a remainder of the contents remaining in the container protected or kept for later consumption.
  • beverage cans In the case of the use of beverage cans, there is also a need on the part of the consumers, provided that after opening a portion of the beverage that remains in the can, the cans can be reclosed, and in particular in situations where the can cannot be parked, for example to be able to hold comfortably at events of the modern leisure society, such as open-air concerts. It is also common for beverage cans to drink directly from them after the closure has been removed. Since the outside of a beverage can is exposed to external environmental influences, it can also be the case that the area around the opening or the closure of the can, which comes into direct contact with the mouth when drinking, is contaminated, which means that the behavior of drinking straight from the can also involves a hygienic problem. Even if there is no visually recognizable contamination in the opening area, it may be the case that there is microbial contamination.
  • the invention also relates to a packaging container for foodstuffs and the use of the packaging container for holding pasty or free-flowing or falling foodstuffs, in accordance with the features in the preambles of claims 51 and 68.
  • Packaging containers made of plastic are used in a large number, in particular in the field of packaging foods, such as, for example, dairy products or ready-made dishes, for example soups or puddings, or else pourable goods, for example muesli.
  • Such cups made of plastic are usually thermoformed with a more or less tapered base body made of a plastic film or manufactured by similar processes.
  • these packaging containers must have a disproportionately high amount of material in order to achieve sufficient strength for normal use, which increases the production costs.
  • a metal foil applied by means of an adhesive is usually used to close this packaging container used for sealing. When this seal is applied, the packaging container is exposed to high mechanical loads, also due to the heat that occurs.
  • the invention has for its object to provide a packaging container, a closure lid, a closure device, a method and a packaging unit, which are sealable and allow a tight and safe reclosure in a simple and safe manner and which achieve high mechanical strength even with economical use of materials.
  • the object of the invention is each independently by a packaging container according to the features of claim 1, by a closure lid according to the features of claim 2, by a packaging unit according to the features of claim 3 and by a method for closing a packaging unit according to the features of Claim 30 solved. It is advantageous that the configuration of the packaging container or the closure lid according to the invention enables the seal to be opened for the first time without deformation, for example the closure lid, and that after the partial removal of the contents it is possible to reclose it securely and tightly by means of the form-fitting coupling device. This is achieved above all by the special arrangement of the two coupling elements, that is to say the positive and non-positive coupling element.
  • Leaktightness of the packaging container leads, as is the case, for example, with coupling elements mounted on the inside between the closure lid and packaging container. It is also advantageous that the formation of one of the sail surface in a radial In the direction of the distant locking element, there is no permanent deformation of the coupling elements due to excessive deformation when the packaging container is opened for the first time while the seal is released. In the case of packaging containers known from the prior art, with form-fitting coupling elements also engaging on the outer circumference, this is not possible due to the direct action of the opening force applied by the user and a resulting bending stress or deformation. In the embodiment of the coupling device according to the invention there is no deformation of the closure cover and the tightness is therefore not impaired.
  • a further advantage is due to the geometrical arrangement of the coupling elements according to the invention that, when opening for the first time, the sealing seam is only opened in time after the form-fitting coupling element and thus an inadvertent opening of the tamper-evident closure is effectively counteracted.
  • the fact that the lid encompasses the packaging container on the outside by means of coupling elements has the additional advantage of catching drops, as a result of which the drops remaining in the edge region after drinking remain inside the packaging container after being closed and thus there is no contamination of the outside of the cup.
  • the advantage is achieved that an additional mechanical stiffening can be achieved by the edges formed in the polygon.
  • the embodiment according to claim 9 achieves the advantage that the width of the sealing surface and thus the directly related adhesive force of the seal are optimal can be adapted to the respective application.
  • the embodiment according to claim 12 has the advantage that this shape is adapted to the commercially available drinking or yoghurt containers and thus good handling is ensured.
  • the advantage is achieved that a high stack density is achieved, and thus transport costs and storage costs can be kept low.
  • the embodiment according to claim 28 is advantageous, since on the one hand this ensures food safety, and on the other hand with good mechanical properties such as strength, resistance to stress cracking or flexural fatigue, the manufacturing or raw material costs can be kept low.
  • the lid is given a high mechanical stability and the tightness is increased by the edges formed in the polygon.
  • An embodiment according to claim 22 has the advantage that placing the closure cover on the packaging container is made considerably easier and tilting of the coupling elements is effectively avoided.
  • the height of the guide area can be individually adapted to the respective cup size.
  • An embodiment according to claim 27 is advantageous, since on the one hand this ensures food-fastness and on the other hand the manufacturing or raw material costs can be kept low with good mechanical properties.
  • the sealing can be carried out inexpensively and in a food-safe manner.
