Description

The present invention relates to a blister pack containing a bottom part with or a plurality of depressions surrounded by a shoulder, the shoulders overall form a coherent, flat shoulder surface, and at least one Covering film covering recesses or recess openings, being in the recesses there is a removable ingredient. The invention further relates to the use the blister pack and a method for manufacturing the same.

It is known base parts, also called product carriers, of blister packs, also push-through packs called, with push-through cover films, for example made of metal, like aluminum. The cover film can be coated with an aluminum film with a sealing layer, like a sealing wax. The aluminum foil is over the sealing layer sealed on the bottom part. The ingredients are removed by Deforming the depression pressed against the cover film, wherein the cover film tears or bursts and releases the ingredient or product. This means that the cover film must be inelastic and easily tearable. For example, with a Sealing layer refined aluminum foils particularly well for this purpose. The described Blister packs contain medicines such as pills, tablets, coated tablets, Ampoules and the like

The ingredients, especially medicines, in their mostly colorful and candy-like Dosage forms arouse children's curiosity. To access special To prevent medication, it is very often advisable to close the opening handles complicate. The aforementioned cover films have the disadvantage that the intended Purpose of easy penetration, a removal of the ingredients from the packaging not an insurmountable obstacle for children either.

DE-A-29 19 713 describes a child-resistant pharmaceutical packaging made from a base film, a push-through film and a security film known. The ingredient can only after complete removal of the security film, for example by peeling off the security film, can be removed from the pack by pushing through, but this is also the case adults, especially older people, can cause trouble.

The object of the present invention is to create a blister pack for children cannot be opened and yet for adults and especially for the elderly is easy to use and open.

According to the invention, this object is achieved in that the shoulder surface in the base part at least one opening aid with at least one opening-effective edge or tip contains with which the cover sheet lying above the recess opening is weakened in this way can be that the ingredient can be pushed out of the recess.

The opening aid is preferably at least partially out of the shoulder surface removable, the opening aid advantageously consisting of one or more by one or more Weakening lines are limited parts of the surface, which extend along the weakening lines remove from the shoulder surface by hand or with aids.

The blister pack according to the invention expediently contains a base part with at least one or a plurality of angular, round or oval depressions, also subjects or Called well. The bottom part can, for example, be rectangular in plan view, the depressions preferably being distributed uniformly and in columns and rows or arranged in opposite directions.

Weakening lines are target dividing lines or target dividing areas along which the Material preferably separated by hand. The lines of weakness are, for example mechanically, such as cutting, punching or scoring with knives, physically Way through e.g. Heat treatment, laser beams, electron beams, spark erosion, Dissolving or swelling by means of solvents or by chemical reaction, e.g. made by etching. The lines of weakness can be completely or partially severed or by changing the material properties as well as by material removal weakened areas in a film.

The base parts of the present blister pack can be embossed, cast, deep-drawn or stretch-drawn or vacuum-formed base parts made of metal, such as aluminum, made of plastic, plastic composites, such as plastic-paper composites or plastic-metal composites. The plastics can also be plastics coated with inorganic layers, in particular coated with SiO _x .

Suitable plastics for floor parts include, for example, films and film composites Olefin-based thermoplastics, such as polyethylenes, polypropylenes or copolymers thereof, ester-based polymers such as polyethylene terephthalates, polyamides or halogen-containing Plastics, such as polyvinyl chlorides or polyvinylidene chlorides or mixtures thereof. The bottom parts can also have a barrier layer against gases and vapors. A such a barrier layer can be, for example, a metal foil embedded in a plastic composite, like an aluminum foil, or one arranged between two plastic layers ceramic or metallic layer. Ceramic and metallic layers can for example by evaporating metals, oxides or nitrides of aluminum, Silicon and other metals and semi-metals in a vacuum and deposit of the substances be generated on a plastic carrier.

The bottom part can also be made of or with cellulose-containing materials, such as paper, cardboard, Cardboard, paper-containing molding compounds, etc. to be made or with the help of such materials be reinforced.

The bottom part consists of or in a preferred embodiment contains polyvinyl chloride (PVC), PVC coated with polyvinylidene chloride (PVdC), cyclo-olefin copolymer (COC) or polychlorotrifluoroethylene (PCTFE). Composite films are also preferred with PCTFE, especially with PCTFE and PVC. The total thickness of the bottom part is for example 100 - 500 µm, especially 200 - 360 µm.

Other preferred film composites for floor elements contain or consist of a outer film made of PVC with a thickness of 60-100 µm, made of another outer film oriented polyamide (oPA) with a thickness of 25-30 µm and an intermediate one Aluminum foil with a thickness of 45-60 µm. You can also use film composites one outer polypropylene film and one aluminum film in between be used.

The cover film is expediently not or only difficult to push through by hand. she can for example from an aluminum foil, in particular from one with a sealing layer refined aluminum foil or a composite containing aluminum foil. The cover film can also be plastics and / or cellulosic materials, such as cardboard or paper contain. In particular, those described above for the base part can be used as plastics, be used. For cover foils made of a plastic-metal composite the metal layer can be in the form of a foil or be vapor-deposited.

Furthermore, especially for single-variety packs, plastic cover films, especially made of polypropylene, without metal foils or layers, which are pierced with the corresponding opening aids described below, can be cut or weakened. The plastics can for example Reduced tear strength and fillers to facilitate opening. The cover sheet can also, e.g. weakened in the area of the recess or Have lines of weakness, which, for example, the opening process using the opening aids are facilitated. However, the lines of weakness are appropriate designed so that the ingredients are beneficial without using the opening aids do not let it push through by hand.

The cover film can, for example, be made of an aluminum film coated with heat seal lacquer a thickness of 8 - 50 µm, in particular 20 - 45 µm, preferably 37 - 43 µm consist.

Furthermore, the cover film can also be a heat seal lacquer coated aluminum film Contain thickness of 20-50 microns, in particular 20-30 microns, preferably 20-25 microns which is an external PET (polyethylene terephthalate) film with a thickness of 10 - 30 µm, in particular of 12 - 20 µm, laminated. In a further variant, the aforementioned Cover film on the plastic film contain a further lamination with paper.

The cover film covers the bottom part, for example, over part or all of the area and closes at least the recess openings. It is useful by gluing or Sealing connected to the bottom part. The sealing layers can, for example, polyolefins, such as polyethylene, polypropylene or polyester, such as polyethylene terephthalate or Contain or consist of polyethylene-2, 6-naphthalate and in foil or lacquer form are present and can for example have a thickness in the range of 1 to 50 microns. Correspondingly, heat seal lacquers can also be used. As adhesives, for example Phenolic resins, epoxy resins, cyanoacrylates, acrylates, modified acrylates and in particular, adhesives based on polyurethane are used.

The cover film expediently withstands the usual push-through forces that are required for removal of the ingredients from the specialization must be used, especially those Push-through powers that children are able to exercise. The resistance of the top layer can result from their tensile strength and / or elasticity.

The opening aids are or advantageously contain surface parts that are expediently from the Protrude shoulder area of the blister pack or along lines of weakness from the Shoulder area can be solved. Furthermore, folding lines can be provided on which the surface part can be bent. The opening aids and the associated surface parts advantageously have opening-effective edges and / or tips which on the can be brought to the opening surface area in the cover film.

Fold lines are appropriately designed in such a way that they can be bent over on these parts without being completely separated. They are not dividing lines, so parts are along a fold line is difficult or impossible to remove by hand.

For example, an elongated tip can be provided which extends along Press lines of weakness, for example perforated lines, out of the base part or can be released and bent so far that its tip on the surface area to be opened of the cover film.

It can also be provided that the opening aid extends completely along lines of weakness can be loosened or separated from the bottom part.

In a further and preferred embodiment variant, each can have a recess in the shoulder surface of the blister pack, a surface piece, expediently without a depression, be provided. The area piece is not with the aforementioned area part as an opening aid to be confused. The patch is bordered by one or more lines of weakness and at least by a fold line from the rest of the bottom part such that the patch along the lines of weakness separated from the bottom part and by Fold down along the fold line over the adjacent recess opening can. The fold line is preferably arranged between the surface piece and the depression.

The pivotable surface piece expediently contains an opening aid, for example how previously described, which when swiveling the patch directly over the Covering film covering the recess opening can be brought, so that the opening aid can be attached directly to the cover film.

The patches can be bent along the fold line. The fold line is intended in particular after repeated folding, there is still a sufficient connection between the surface piece and the rest of the blister pack. The fold line is expediently designed in this way be that the patch is in both directions, for example clockwise and swings counterclockwise.

The depressions of a blister pack can, for example, preferably be in columns and rows be arranged in two columns. Each column of wells is for example another column of sheets, each containing an opening aid, assigned. The column of sheets is advantageous over a fold line with the column of the wells connected. The individual patches are otherwise through Lines of weakness against each other or against the adjacent shoulder areas of the depressions delimited.

In a further embodiment, the depressions of a blister pack can be mutual be staggered, the patches with opening aids, also mutually offset, are each arranged between at least two depressions. Thereby can make better use of the existing area of the base part and save packaging material because the area pieces with the opening aids, for example, take up less space claim as the recesses surrounded by shoulders.

In a particularly preferred embodiment variant, the opening aid is in the form of individual ones or a plurality of teeth, preferably in the form of points or zakken, educated. The tips or spikes or the lines of weakness in the blister pack outlined triangular shapes are advantageously circular and with their end points the tips or spikes are preferably arranged around a common point in the base part, so that when the tips or spikes are pushed out of the base part, a circular or polygon-shaped spike or lace crown. The lines of weakness in the bottom part are arranged, for example, in a star shape crossing each other, whereby two adjacent end points of weakening lines are connected by a folding line can be so that the spikes or tips along this fold line are better off the Level can be opened.

The opening aid in the form of a crown is preferably in one piece of the above described type provided. The distance from the center of the recess opening to Fold line between the patch and the shoulder adjacent to the depression corresponds preferably the distance described by the circular or polygonal crown Center point to the fold line, so that when the flat piece is folded over, the crown is more concentric Position to the recess or the recess opening comes to rest. The diameter the circle enclosed by the teeth or tips is suitably smaller or preferably equal to the diameter of the recess opening.

By folding the surface piece onto the convex side of the recess (side on which the recess protrudes) by pushing the recess through the Opening aid, the prongs or tips are folded out of the plane of the patch and in an opening effective position perpendicular or almost vertical to the area piece to be brought. The teeth or teeth can also be used with a finger or with other aids are brought from the level to the opening position.

To expose the ingredient, the patch with the protruding teeth or Point first on the concave side of the recess (side on which the recess deepens is), i.e. placed on the recess opening. Drill and cut the prongs or tips circular in the cover over the recess opening and injure or weaken this to the extent that the ingredient is subsequently pressed out of the recess by hand can be.

Further design variants can be analogous to that described above, for example as an opening aid instead of a serrated crown area parts with effective opening Edges or one or more serrations or tips can be provided.

Furthermore, it can be provided that the surface parts of the opening aid release out the bottom part by folding against itself into a stable opening tool, preferably into a spitz that can be shaped. Furthermore, one of the Form of a semicircle weakening line released opening aid as semicircular cutting tool can be used.

A variant of the special type shows a blister pack with an opening aid, which is arranged in the shoulder area of the blister pack or on the edge thereof and is appropriately outlined by lines of weakness and is advantageous from the shoulder area can be at least partially detached, the detached part of the opening aid has at least one opening-effective edge, such as cutting edge, tip or prong. The opening or tip is preferably from the four-well opening directed away. On the edge of the blister pack facing the opening aid advantageously arranged a curling element and with the edge portion, e.g. by sealing or gluing. To open the recess opening, the shoulder area with With the help of the rolling element rolled up from the edge, the cover film when rolling expediently lies on the inside. As soon as the roll-up element covers the area the opening aid starts to roll up, this is due to the resulting bending stresses detached from the shoulder area along the lines of weakness and is preferably tangential from the rolled-up shoulder area. As the shoulder area rolls up the protruding opening aid with the shoulder area around the roll-up element wrapped and hits with its opening-effective edge or tip, preferably vertically, on the cover film, the distances between the opening aid and the recess and between the opening aid and the edge or roll-up element are selected such that the opening-effective edge or tip of the cover film preferably in the edge region of the Penetration opening penetrates at least in sections or weakens it, so that the ingredient can be pushed out of the recess. The weakening of the cover film has the function of a tear notch along which the cover film begins to tear when pressure is applied vertically to the cover film and releases the ingredient. The lines of weakness can be as described above be executed.

The blister pack advantageously has appropriate locations on its outside Inscriptions and graphic elements, which among other things the individual Suggest opening steps.

A blister pack according to the invention can be produced from a flat composite film Wells are formed and an ingredient is filled into the wells is and a cover film on the composite film over the recess openings of the recesses is sealed and fold lines and / or in the composite film with cover film Lines of weakness of the opening aids are attached and blister packs with a or more wells.

Furthermore, blister packs with several wells can also be cut before the fold lines and / or lines of weakness of the patches are attached.

If the blister pack contains rolling elements, these can be used in the sealing device the cover film on the blister pack to be produced, preferably on the provided edge area of the blister pack, sealed or glued.

The contents of a pack according to the present invention can only be carried out after execution taken from a regulated sequence of opening handles, i.e. through the cover film be pressed out of the recess. This is an almost impossible task for children they can hardly make several simultaneous movements in succession. In particular pushing the opening aids out of the bottom part and using the Children do not intuitively perform opening aids to damage the cover film, but requires certain prior knowledge or the ability to read package instructions ahead. For older people, on the other hand, opening such a package is quite easy.
