Definitions

  • the invention relates to a cover made of cardboard.
  • closure covers have become known on the one hand as so-called overlapping covers, on the other hand as so-called insert covers, and the invention is directed to both types of covers.
  • Cans for holding foods or the like which are made from cardboard are known to a large extent today. Although these containers are covered with a wafer-thin layer of plastic, they decompose in the garbage and therefore do not represent a long-term pollution of the environment. H. are trained to be environmentally friendly.
  • lids of such containers are still completely made of plastic to this day, since it was not possible to produce dimensionally stable lids from cardboard. It must be noted here that the lids are placed on the can only after a long time after their manufacture, namely after the can in a filling plant or the like Good to be picked up is filled. In the meantime, deformations cannot be excluded. In addition, environmental influences such as temperature and moisture act on the lid and contribute to the deformation of the lid.
  • lids are therefore without question a burden on the environment and are a disposal problem, while a closure lid made of cardboard - that is, the same material as the can body - would not have to be disposed of separately from the can.
  • the invention has for its object to provide a lid for cans or can-like containers, which can be made of cardboard and still has the required strength, in particular the necessary stability.
  • the circumferential, upward or downward flange of a lid - depending on whether it is an overlapping lid or an insert lid - is provided with a stabilizing ring which is firmly attached to the outside or inside of the flange. Since the lids as well as the cans are provided with a wafer-thin plastic covering, it is now possible to fuse the thin plastic layers that come into contact with each other by applying heat to the area of the circumferential stabilizing edge or flange and by applying appropriate pressure, so that the stabilizing edge is firmly attached to the normal circumferential flange. Surprisingly, it was found that this simple measure enables the lid to have a high level of stability.
  • a box 1 is drawn, which has an overlap 2, the overlap 2 is equipped in a manner known per se with a downward rotating flange 3.
  • the overlap 2 engages with its downward flange 3 over the outside of the upper edge of the box 1.
  • the downward flange 3 carries a tear tab 22, so that in certain embodiments of the overlap 2 a loosening of the overlap by actuating the tear tab and thus Separation of the flange 3 in two parts is possible.
  • a cardboard blank 20 is assumed (FIG. 2), which is equipped, at least in its edge region, with grooves 21 which prevent the flange to be bent later from being reset.
  • the circumferential flange 3a of a cover 2a is bent inwards and forms a stabilizing ring 4a in this way.
  • This stabilizing ring 4a is pressed under the influence of heat on the inside of the downward flange 3a and by fusing the thin plastic layer fixed so that the lid shown in Fig. 4 is achieved.
  • an adhesive bond can also be used so that the adhesive layer acts instead of the plastic layer.
  • FIGS. 5 and 6 makes it clear that it is possible to extend the flange 4a to a greater or lesser extent, ie. H. high enough to weld on the inside of the flange 3a, so that the upper part of the stabilizing ring 4a or 4b protrudes more or less inwards. From the illustration in Fig. 13 it can be seen that a securing of the lid 2a is achieved, which makes it possible either to clamp the lid 2a particularly tightly on the can 1a or to form it as a security lid, so that it even provides security against unwanted opening there.
  • the downward circumferential flange 3c is bent inwards as before.
  • a reinforcing ring 5 is inserted into the U-shaped space thus created.
  • This reinforcing ring 5 is then firmly connected to the circumferential flange 3c by the action of heat, specifically also to the inside of the bent edge of this flange 3c.
  • an additional stabilizing ring 4b is provided, which is J-shaped in the illustrated embodiment.
  • the small leg lies on the inside of the circumferential flange 3b of an overlapping cover 2b directed downward and the large flange of the stabilizing ring 4b lies on the outside of the flange 3b.
  • B. by the heat of the flange 3b firmly connected to the stabilizing ring 4b.
  • 11 denotes a closure cover, which essentially consists of a bottom 12 and an upright edge 3.
  • Fig. 11 shows that the free edge of the edge 13 are bent outwards, i. H.
  • a U-shaped flange 15 is created in the upper region of the edge 13. If this U-shaped flange 15 is now exposed to pressure from the outside inwards, the U-shaped flange 15 bears against the outside of the edge 13 and - since the starting material has been provided with a fine plastic coating - the heat can now be applied Flange 15 are glued to the outside of the edge and then forms a stabilization ring 14 which can be seen in FIG. 12.
  • This stabilization ring 14 has the effect that the bent edge 13 can no longer be reset, i. H. a closure cap 11 is created which is dimensionally stable and which can also be placed on the filled can for a long time after its manufacture in the filling factory.
  • a can 1a with a cover 2a is shown to clarify the application, this cover 2a being formed by the protruding stabilizing flange 4a as a safety cover, which is provided with a tear-open tab 22.
