Definitions

  • the present invention relates to a container with a heat-welded peel-off lid having an improved anchorage region.
  • EP-A-0 299 571 is a container for milk, cream and the like, with a filling cavity joined with a flat circumferential stiff rim and a cover sheet which is connected by means of a sealing connecting seam to the flat rim.
  • the rim and cover have a portion extended beyond the connecting seam, a channel communication with the filling cavity being formed in the extended rim portion, the channel being surrounded, beyond the connecting seam, by an additional sealing seam which is weaker than a connecting seam portion extending transversally to said channel.
  • the cover portion extended beyond the connecting seam can be pulled away up to such transversal connecting seal portion.
  • DE-U-9 114 409 discloses a container with a lid wherein the main part of the circumference of the lid is connected to the container by a permanent adhesive and a smaller part, which is shaped as a circle sector, connected to the container by a fixing adhesive.
  • the aim of the present invention is to eliminate or substantially reduce the problems described above by providing a container which allows to keep the lid associated with the container.
  • an object of the present invention is to provide a container which improves the use of the container itself.
  • the present invention comprises a container 1 with a heat-welded peel-off lid 2.
  • the heat-weld of the lid 2 on the container 1 has at least one preset portion or anchorage region, designated by the reference numeral 3 in the above described figures, which provides a high degree of resistance to mutual separation.
  • the preset portion 3 comprises an arcuate portion 4 and at least two spot-welds 5 and 6 produced at the ends of the arcuate portion 4; said spot-welds cooperate, whereby to resist separation of the lid 2 from the container 1, obtaining at the same time, as shown in figures 1 and 3, the possibility of easily extracting any product contained therein.
  • a heat-welding head designated by the reference numeral 7, comprises at least one raised portion, designated by the reference numeral 8, which allows to heat-weld the lid 2 onto the container 1, which features the portion 3 with high resistance to mutual separation.
  • the raised portion 8 comprises an arcuate portion 9 at the end of which protrusions 10 and 11 are formed, in order to define the complementarily shaped arcuate portion 4 of high-resistance weld and the spot-welds 5 and 6, as previously described.
  • the container according to the invention can be recycled together with its respective lid.
  • the container can accommodate any product, replacing packages which are more expensive or more difficult to recycle.
  • the materials employed, as well as the dimensions, may be any according to the requirements.
