Definitions

  • the invention relates to a lid made of aluminum or a composite material with a reclosable opening according to the preamble of patent claim 1.
  • the invention further relates to a method for producing a cover with a reclosable opening according to the preamble of patent claim 9.
  • Lids made of a composite material for example of several layers of thermoplastics, in which an aluminum foil is embedded as gas and light protection and which have a drinking or pouring opening are known.
  • the aluminum of the aluminum foil is exposed along the punched edge and can be used with the Fill material come into contact.
  • the aluminum can corrode and lead to contamination of the contents.
  • the invention seeks to remedy this.
  • the invention has for its object to provide a pouring and drinking opening, the edges of which are protected against corrosion, and in which the part of the lid which closes the drinking opening can be reused as a closure pin after being torn open.
  • the invention solves these problems with a cover according to the characterizing features of patent claim 1 and by a method for its production according to the characterizing features of patent claim 9.
  • the advantages achieved by the invention are essentially Chen can be seen in the fact that the lids can be produced in a continuous production process from band-shaped material, wherein the lid blanks or the blanks provided with drinking or pouring openings and reclosure can be stored rolled up until they are applied to the container.
  • the drinking opening can be closed again and again with the integrated closing pin because the sealing edge remaining on the inside of the lid and reinforcing the edge of the opening gives it a stiffening.
  • the cut edge along the opening can be safely covered against the filling material by the edge overlapping the opening.
  • the central part that forms the closure is lifted up and detached from the edge along the predetermined breaking point.
  • the area of the lid surrounding the opening is protected from below by the sealing edge which remains on the lid and surrounds the opening.
  • the collar-shaped extension of the closure and the edge on the closure enable the closure to be held securely inside half of the opening if it is put back on the lid after the first opening.
  • the edge set back or offset from the surface of the closure by the thickness of the cover enables the tear-open tab to be sealed to the cover and the surface of the closure at the same time.
  • the lid 1 shown in Figure 1 on a container 29 (shown in broken lines) with a reclosable opening 3 consists of aluminum or a composite material which, for example as gas and light protection, an aluminum foil 5, as a sealing layer 7 a heat-sealable plastic, such as Surlyn by Dupont de Nemour, and have a tear-resistant plastic as cover layer 9.
  • a plastic insert 13 is inserted which, after being torn open, forms both the reclosure 15, short closure 15, and the reinforcing edge 17, short edge 17, in the the closure 15 can be inserted.
  • the edge 17 is firmly sealed from below with the lid.
  • a thin tear-open tab 19 is inextricably connected to both the cover 1 and the closure 15 above the opening 3. So that a flat sealing surface is created, the edge 17 is set back by the thickness e of the cover 1 relative to the surface of the closure 15.
  • the three parts can be connected by mutual sealing.
  • the closure 15 and the edge 17 are connected by a web 21, which serves as a predetermined breaking point and breaks when the closure 15 is lifted with the tear-open tab 19, which preferably has a tab 23 that can be easily lifted off the lid 1 at one point.
  • the thickness of the web 21 is dimensioned; it is therefore in the range of hundredths of a millimeter to a few tenths of a millimeter.
  • FIG. 2 shows an enlarged representation of a plastic insert 13 with a solid edge 17 and a closure 15 with a collar 25 directed towards the interior of the container.
  • the diameter D of the collar 25 on the free edge 27 is larger than the diameter d of the opening 3 or the diameter of the plastic insert 13 at the predetermined breaking point.
  • the diameter D of the collar 25 preferably increases toward the free edge 27.
  • a bead 31 is attached to the collar 25 according to FIG. 3, the diameter E of which is larger than that Diameter d of the opening 3.
  • the bead 31 can run completely; it can also be attached only in sections, for example on the “narrow sides” of the closure 15 (cf. FIG. 6).
  • the web 21 serving as a predetermined breaking point and the edge 17 are designed to be significantly finer in this example than the closure 15.
  • the plastic inserts 13 described above with integrated reclosure 15 and reinforcing edge 17 for latching are very simple and inexpensive in injection molding drive to manufacture.
  • the subsequent assembly can be carried out in a continuous process with the material for the cover 1 and the tear-open tabs 19, which is supplied in the form of a tape, using conventional machines.
  • the strip-shaped material 2 for the cover 1 which is brought to a punching and punching machine 35, is unwound from a coil 33 and the opening 3 is punched out. Then, again from coil 37, the tear-open tab 19 is punched out and brought from below to the perforated cover 1 and positioned thereon and initially stapled by means of sealing points.
  • the plastic inserts 13 are individually removed from a stack 41 and inserted into the opening 3 and stapled.
  • the plastic insert 13 is sealed along the edge 17 with the sealing layer 7 of the material 2 for the lid 1 and the reclosure 15 with the tear-open tab 19.
  • the tape 2 provided with the ready-to-use closures 13 and the tear-open tabs 19 can now be wound up and delivered to the consumer in tape form or can be fed directly to a punching machine for punching out the cover 1.
  • plastic insert 13 could also be applied first and the tear-open tab 19 sealed with the closure 15 and the cover 1 only afterwards.
  • the pull tab 19 is pulled up on the loose tab 23 and peeled off from the lid 1.
  • the seal or adhesive bond between the tear tab 19 and the closure 15 is not detachable. For this reason, the closure 15 is also raised when the tab 23 is pulled up further.
  • the web 21 breaks, i.e. the predetermined breaking point, and the closure 15 remains on the tear tab 19.
  • the edge 17 remains on the inside of the lid 1 and forms a circumferential reinforcement of the opening 3 and at the same time serves as a catch when the closure 15 is pushed back into the opening 3 in order to close the container 29 again.
  • the bead 31 (cf. FIG. 3) can, for example, only be attached along the arcuate sections so that the closure 15 snaps into place and is held in place.
