Definitions

  • the invention relates to a blister pack with a Blisterteilteil and sealed against the Blisterteil transparent or translucent metal foil-free push-through cover sheet and a method for producing the blister.
  • Known push-through or blister packs consist of a blister base part and a cover foil which is sealed against the blister bottom part and closes the pack.
  • a blister pack known for metered packaging of pharmaceutical products, such as tablets usually has a multiplicity of individual small containers in the form of cup-shaped depressions formed in the bottom blister in the blister bottom part for receiving the tablets. To remove a single tablet from a blister pack the corresponding recess is pressed in the bottom part and in this case the tablet pushed through the lid material.
  • the cover sheet is an aluminum foil or a composite foil of an aluminum foil with further layers of plastic or paper.
  • the aluminum foil is a preferred lidding material for blister packs, since at the selected thicknesses of the lid materials relatively low breaking forces are necessary, the required piercing energy is thus low and the aluminum has a low elongation.
  • the bottom part of the blister pack consists of plastic, such as, for example, PVC, polyamide, polyolefin, polyethylene terephthalate and composite films constructed of at least one of these materials and optionally also containing an aluminum foil.
  • plastic pervious films whereby the puncture property of the plastic film is achieved by embedding fillers in the matrix.
  • the fillers are considered in terms of their composition and their partly chosen so that a weakening of the surrounding plastic matrix occurs, whereby the puncture resistance of the film is lowered so that the packaged goods can push through tearing or breaking the film through them. Due to the requirement that the selection of the fillers and in particular their proportions in the plastic matrix, the puncture property of the film should be ensured, resulting always opaque press-through films.
  • EP-A-0 613 832 discloses a metal foil-free cover sheet comprising at least one polyolefin or polyester-based thermoplastic film having a filler content of 5 to 50% by weight.
  • Preferred plastic is polyethylene
  • fillers are, for example, chalk and talc.
  • a transparent push-through foil with a polyolefin-containing polymer phase is known.
  • the polymer phase contains a hydrocarbon resin component in dissolved form with pendant cyclic groups on the polymer chain.
  • Preferred polyolefins are polyethylene, polypropylene or a co- or terpolymer of ethylene and / or propylene.
  • filler such as chalk or talc, may be embedded in the polymer composition.
  • the invention has for its object to provide a suitable for sealing against all common floor materials cover sheet, which is transparent or translucent and free of metal foil and at the same time has a brittleness, which has comparable through-pressure characteristics with a conventional, containing an aluminum foil push-through.
  • a further object of the invention is to provide a metal foil-free, push-through cover sheet suitable for applications with RFID tags, on which RFID antennas of RFID tags for the HF (13.56 MHz) range can be printed without attenuation of the electromagnetic radiation.
  • the cover film contains at least one layer of cycloolefin copolymer (COC) or cycloolefin polymer (COP).
  • Cycloolefin copolymer (COC) and cycloolefin polymer (COP) are highly transparent materials with excellent barrier to water vapor transmission, can be coextruded with other materials such as polyethylene or polypropylene, and are also very brittle. These properties provide ideal conditions for the use of cycloolefin copolymer (COC) and cycloolefin polymer (COP) for the production of push-through films. It is possible with this material fürdschreibfolien achieve with fürdschreibfolien similar to the fürdschreibfolien produced in large quantities mainly from aluminum foil of a thickness of 20 microns.
  • the transparent materials may e.g. dyed with titanium dioxide or printed white. Although these materials are no longer transparent, they are still translucent.
  • the cover film is preferably provided in layers on the side facing against the blister side with a hot-sealing lacquer layer or a coextruded heat seal, the seal to blister base made of PVC, ACLAR ®, PP, PE, PS, Formpack ® or PA.
  • the cover sheet with a thermally stable at sealing temperature lacquer layer or with a coextruded, at sealing temperature thermally stable plastic layer preferably from COC, COP, PP, PA or PET, be provided.
  • the cover film has a preferred thickness of 5 to 60 .mu.m, in particular 10 to 30 .mu.m.
  • the blister base part is sealed on the bottom part of the sealed cover sheet of a material whose chemical structure is compatible with that of the plastic film sealed against the blister base part.
  • the cover film according to the invention is also suitable for applications with RFID tags.
  • Examples of materials used to make blister sheet parts are films of PVC, PVDC, PP, PET, PE, PS; PA and composite films such as PVC / ACLAR® (PCTFE), PVC / PVDC, COC and COP or FORMPACK® (AI-AI blister).
  • both the cover foil and the bottom foil can be printed.
  • FIG. 1 is a plan view of the Blisterteilteil a blister pack.
  • FIG. 2 shows a cross section through the blister pack of FIG. 1 along the line I-I;
  • FIG. 3 is a plan view of the cover sheet of the blister pack of FIG. 1;
  • FIG. 4 shows a cross section through a first cover sheet
  • FIG. - Fig. 5 shows a cross section through a second cover sheet.
  • a blister pack 10 shown in Figs. 1 to 3 consists of a Blisterteil 12 formed out of a bottom foil, cup-shaped containers 14.
  • the containers 14 are tablets 16.
  • As a closure for the containers 14 is a the openings of the containers 14 spanning cover sheet 18 sealed against the blister base 12.
  • a first cover film 18 shown by way of example in FIG. 4 consists of a core film 20 of mLLDPE (metallocene-based linear low-density polyethylene) of a thickness of 10 .mu.m with co-extruded COC films 22, 24 of 5 .mu.m thickness.
  • mLLDPE metalocene-based linear low-density polyethylene
  • the later to be sealed against a Blister foundedteil 12 side of the cover sheet 18 is coated with a Heissgueellack harsh 26 has a thickness of 2 microns, optionally provided with a printed outside with a transparent protective lacquer layer 28 of a thickness of 2 microns.
  • a second embodiment of a cover film 18, shown by way of example in FIG. 5, consists of a core film 30 made of COC with a thickness of 10 .mu.m and films of 5 .mu.m thickness coextruded on both sides.
