Definitions

  • the present invention relates to an opening device for a container, in particular for a sealed container for packaging pourable food products, and to a method for producing an opening device.
  • the packaging material also comprises a layer of gas-barrier material, e.g. aluminium foil or ethyl vinyl alcohol (EVOH) film, which is superimposed on a layer of heat-sealable plastic material, and is in turn covered with another layer of heat-sealable plastic material forming the inner face of the container eventually contacting the food product.
  • gas-barrier material e.g. aluminium foil or ethyl vinyl alcohol (EVOH) film
  • Containers of this sort are normally produced on fully automatic packaging machines, on which a continuous tube is formed from the web-fed packaging material.
  • the web of packaging material is sterilized in the packaging machine.
  • the web of packaging material so sterilized is then maintained in a closed, sterile environment, and is folded and sealed longitudinally to form a vertical tube.
  • the packaging material may be cut into blanks, which are formed into containers on forming spindles, and the containers are filled with the food product and sealed.
  • a container known by the trade name Tetra Rex (registered trademark).
  • a drawback of the above-disclosed opening device is that the pull-ring may protrude outside of the pouring spout. This is due to the shrinkage of the plastic material after molding.
  • the portion of the pull-ring that extends from the pouring spout may interact with parts of the packaging machine when the packaging material - onto which the opening device has been molded - is advanced through the packaging machine. Such an interaction may cause damages to the portion of the pull-ring that extends from the pouring spout and/or to the parts of the packaging machine, which may be worn due to the friction.
  • Another object of the present invention is to provide an opening device that is not damaged by the interaction with parts of a packaging machine, when the opening device is attached to a packaging material and is advanced through the packaging machine together with the packaging material.
  • an opening device as claimed in claim 1.
  • first covering layer 5a, the second covering layer 5b, the barrier layer 6 and the third covering layer 5c define lamination layers applied to the base layer 4 when producing the packaging material 3 in the form of a continuous sheet.
  • the receiving portion 2 is defined by a so-called pre-laminated hole, i.e. a hole 9 formed through the base layer 4 and covered by the above-mentioned lamination layers so that the hole 9 is sealed by a sheet cover portion 10.
  • the opening device 1 further comprises a closing element 15 closing or sealing the pouring opening 14 and integrally connected to the pouring spout 12 by a smaller-section, annular membrane 16.
  • the pouring spout 12 further comprises an annular flange 20 fixed to the packaging material 3 at the edge of the hole 9.
  • the neck 13 projects axially and integrally from an annular region of flange 20 radially interposed between an outer edge 21 of the flange 20 and the annular membrane 16.
  • the closing element 15 defines a prolongation of the flange 20 inside the pouring spout 12 and closes or seals one axial end 22 of the pouring spout 12.
