Definitions

  • the present invention relates to a cover for closing a container having a peripheral rim at its entry, a cover formed by at least one sheet element carrying at least one layer of plastic material intended to be fixed to the rim of the container, and whose sheet element and plastic layer have deformations preventing it from bending.
  • the lids which are used to close the yoghurt pots and many other containers are generally cut from a strip made up of at least two superimposed materials having different physical properties.
  • the present invention proposes to provide a solution to these problems and, to do this, it relates to a cover which is characterized in that the deformations are delimited by closed lines having no point of intersection.
  • the lids with such deformations no longer tend to bend and can therefore be handled and stored without special precautions. They are also easily unstackable, which eliminates the risk that certain containers are badly or not closed at the outlet of the packaging machines. They also have the advantage of not having areas of least resistance and of retaining an attractive appearance.
  • the part of the lid which is intended to be fixed on the edge the container is preferably free of deformations, which allows it to be fixed on the container more securely and perfectly sealed.
  • the cover may also be provided with an internal deformation, the center of which substantially coincides with its own, the external and internal deformations can also be connected by intermediate deformations distributed in a distribution that is substantially symmetrical with respect to in the center of the cover.
  • Figures 1 to 3 show a generally circular lid intended to close a yogurt pot 1 having a peripheral rim 2 at its entry.
  • This cover consists of a sheet of paper or aluminum 3 whose thickness can be between 10 and 150 g / m2 and a layer of plastic material 4 whose thickness can be of the order of 1 at 150 g / m2.
  • Layer 4 is intended to be fixed in a manner known per se to the rim 2 of the yogurt pot. Thus it could for example be by heat sealing, insofar as the rim 2 would be made of plastic or coated with a layer of plastic. It can be applied in a conventional manner to the paper or aluminum sheet, both by coating and by gluing.
  • the cover has an annular border 5 intended to cooperate with the rim 2 of the container and extending outwardly with a protrusion forming a tearing tab 6.
  • the deformations 7 and 8 are annular and have the same width.
  • the deformations 9 are radial and as wide as the deformations 7 and 8.
  • deformations 7, 8 and 9 are delimited by closed lines having no point of intersection, these lines comprising rectilinear sections connected to circular sections by rounded sections.
  • the resistance tests carried out during the development of the invention have in fact shown that it is desirable to avoid the rectilinear and / or circular sections of the closed lines forming sharp angles between them.
  • the deformations can have a depth of the order of 20 to 150 ⁇ m, preferably close to the thickness of the complex. They are produced for example during the cutting of the cover, by pushing back by stamping preferably the most resistant material. Thus, in the embodiment shown in FIGS. 1 to 3, the stamping is carried out by pressing the sheet of paper or aluminum 3 in the direction of the plastic layer 4.
  • Figure 4 shows a cover for closing a yogurt pot (not shown) having a square entrance.
  • This cover comprises a peripheral border 5a intended to cooperate with the rim of the pot and the width of which corresponds substantially to that of said rim, an external deformation 7a internally running along its border 5a, a circular internal deformation 8a whose center coincides with that of the deformation external 7a and rectilinear intermediate deformations 9a connecting the deformations 7a and 8a, the longitudinal axis of the deformations 9a coinciding with the diagonals of the cover.
  • the deformations 7a, 8a and 9a have substantially the same width and, like those of the cover described with reference to FIGS. 1 to 3, they are delimited by closed lines having no point of intersection, these lines comprising straight sections connected by rounded sections to other straight sections or to circular sections.
  • FIG. 5 represents a cover which differs from that shown in FIG. 4 only by the fact that the axes of its deformations inter 9b coincide with its perpendicular bisectors and not with its diagonals.
  • its peripheral border 5b and its external deformations 7b and internal 8b correspond respectively to the peripheral border 5a and to the deformations 7a and 8a visible in FIG. 4.
  • the cover consists only of two superimposed elements. It goes without saying, however, that it could be produced from a complex formed from more than two materials. This is how it could for example understand, from the outside to the inside when it rests on the rim of the container to be closed: . a sheet of paper having a thickness of 10 to 150 g / m2; . a layer of aqueous adhesive having a thickness of 1 to 10 g / m2; . a polyester layer (metallized or not) having a thickness of 5 to 100 g / m2; and . a layer of thermobonding plastic (for example polyethylene) from 1 to 150 g / m2.
