Description

The present invention relates to a multi-part label for attaching information on blister packs with respect to the packaging surfaces enlarged labeling surface, consisting of a sheet-like base member which, without significantly hindering the removal of the packaged objects, for fixing the label on the label to be labeled packaging, and a plurality of sheet-like information carriers, which are hingedly attached to the base member.

For the distribution of smaller quantities of small parts, these have been packed in small packages for a long time and to an increasing extent. The advantage of this measure is to provide the consumer with a manageable stock of material, and at the same time facilitate the sales process itself, for example by self-service option. Thus, e.g. Screws or nails, sorted by size and embodiment, sold in small packages. Small technical assemblies, such as Small transformers, operational amplifiers, printer cartridges or small internal combustion engines for aircraft models, are also offered for safe transport and distribution in small packagings sold commercially. In general, it can be said that all articles and materials that should be safely protected in a relatively small amount to a user or consumer, are conveniently packed in small containers.

This applies in particular to materials intended for the medical treatment of humans and animals, or to be used for scientific purposes and / or with special care. It is therefore imperative that medicines and, for example, clinical investigational medicinal products reach the user or consumer in safe packaging adapted to the nature of the packaged product.

A problem now arises when the consumer or user should or must be given information about the contents of the package. Especially with drugs and investigational drugs, there is a need to provide the user or consumer with extensive, detailed information on properties, handling and any precautions to take when using the package contents. In many cases, in particular for medicinal products and investigational medicinal products, there are legal requirements on the amount of information to be transmitted, some of which vary from country to country, so that in the case of global business there is a need to pass on country-specific information in the national languages to consumers and users ,

For example, the labeling of clinical trials with study-relevant data is becoming more and more differentiated due to EC GMP recommendations and directives, as well as national requirements, and yet aims to provide the highest level of flexibility in the use of medication in as many countries as possible.

So far, especially small primary and secondary packaging could only be marked on the packaging surfaces themselves, which of course were limited by the size of the packaging. The application of information, in particular the various legally binding instructions and safety and handling information by means of labeling, printing, embossing, punching, stoving or other methods was therefore very impaired or became impossible to the extent required. Although the amount of information that can be applied can be increased to a certain extent by reducing the font size, this is at the cost of readability and clarity.

There are already known approaches to make packaging so that they can carry more content-related information than find space on their surface.

From the EP-A-833 295 a label for containers is known in which a plurality of folded information sheets are enclosed between a base sheet glued to the container and a cover sheet attached thereto. The cover sheet is attached at its two ends on the container by adhesive surfaces so that one of the adhesive surfaces is a pressure-sensitive surface, which can be opened and closed again. After opening the adhesive surface, the information sheets can be taken. After inspecting the information, the information sheets can be reinserted between the bottom sheet and the cover sheet and the cover sheet at the pressure-sensitive adhesive surface closed. A major disadvantage of this label is that the information sheets can be separated from the container, lost and exchanged.

From the CA-A-2216094 For example, a device is known which makes it possible to provide information about medicaments to specific persons and for specific purposes. The device, which can be attached to the drug package, consists of several information sheets, which are separably connected at their edges via pressure-sensitive adhesive surfaces in a strip and then folded in a zigzag to form a stack. The individual information sheets are separated from the stack and distributed as intended. Thus, this device does not provide a label for safe, permanent labeling of the package contents.

The problems are greatly increased when it is necessary to attach information to blister packs. As is known, these packages generally consist of a regular arrangement of a large number of trough-shaped depressions which have been produced in an otherwise flat plastic film-as a rule by deep drawing-and a cover which is fixed on the flat residual surface of the film. The trough-shaped depressions serve to receive the packaged objects, e.g. Tablets or capsules, and the cover protects the objects from falling out and from harmful environmental influences.

To remove the objects, the tray bottoms are pushed toward the cover, thereby pressing the packaged objects onto the cover. The Cover tears under the pressure of the packaged object locally, ie over the opening of the tray to be emptied and releases the object.

Because of the unevenness of the tub side of such a package, more extensive content related information can only be found on the cover side, i. on the cover itself, be applied. Here, however, there is not only the disadvantage of very limited space but it is added that the information-bearing cover is destroyed when removing the goods, so that it is very difficult or impossible to decipher the information printed there.

US 3207301 A discloses a package having an information carrier (12) attached to the package by means of a thermoplastic or heat sealable coating. The packaging is a sandwich packaging of 2 layers, of which at least one is provided with the Heißverklebbaren coating. In between are the tablets packaged in a blister pack. By way of example, the thermal attachment of the information carrier is shown via a position of the packaging on the side of the tub of the blister pack.

By doing U.S. Patent 4,955,481 is a folding box with 3 flaps, which includes a blister pack described. The carton is in one piece and has next to a cover flap, a base flap and a protective flap, each with corresponding openings for the blisters, between which the blister pack is fixed. The flaps completely enclose the blisters. On the carton information can be printed, which are printed or glued on the inside of the cover.

Of course, the user or consumer could be provided with the required information through leaflets, but this type of information transfer does not meet the requirements of the AMG, according to which, in particular, for clinical A permanent application of the information and markings on the packaging itself is prescribed. There is always the risk of losing them with loose leaflets.

There has therefore long been an urgent need for a way to provide packaging with a relation to the entire packaging area considerably enlarged information surface.

Moreover, especially in the medical field there is a need to transfer information about the content or the coding of the contents of containers to other objects, to specific groups of persons or to have available for documentation purposes. When possible, sources of error should be switched off.

In the EP-B-0 463 193 In order to solve this problem, it is proposed to use a strip-shaped adhesive-backed self-adhesive label having a length greater than the circumference of the bottle to identify a package such as a cylindrical bottle, the overlapping portion of the strip being formed as a separable portion. On the front is the label strip provided in the overlap area with an adhesive-repellent smooth layer. If the label is glued around the bottle, the separable portion comes to lie on the smooth layer. It can therefore be withdrawn together with its back pressure-sensitive adhesive layer from the bottle, and on another object, such as a syringe, which has been raised from the bottle, are glued.

The multi-part label according to the invention described in the following sections meets these requirements. It is technically simple and inexpensive to produce, provides an integral with the packaging or firmly connected information surface, which is a multiple of the area, which is available on the blister itself, and it thus carries both EC directives and national Specifications invoice. It thus provides a secure solution to the problem of providing legible information in a clear layout, with clear language, country-specific and classifying structure to the user, consumer or user.
The ability to expand the space of the multi-part label according to the invention as needed, a flexible label concept is provided, which takes into account all customer-specific requirements and therefore can be used in a variety of sectors in trade, commerce and industry with advantage.

For example, the multi-part labels of the invention may be used in the pharmaceutical and chemical industries for the packaging of medical products such as pellets, tablets, capsules, ampoules, vials and pre-filled syringes, or crop protection agents such as insect killing capsules, pellet or tablet form fertilizers safe dosage, or in the cosmetics sector eg for Gebißreinigertabletten, in the food industry eg for food supplements such as vitamin preparations and drinking ampoules, in the metal industry, in tool and machine construction and the automotive industry for small and spare parts, in the household industry eg detergent and Spülmaschinentabs , as well as in all other areas, where by means of the multi-part label according to the invention a comprehensive, clear, non-loseable information document to be applied to a primary or secondary packaging, are used with particular advantage.

The multi-part label according to the invention, its features and functions are described below primarily in connection with a blister pack, which is produced by a deformation process from a thermoforming sheet and sealed after filling by a cover film. Of course, the labels according to the invention are also suitable for labeling blister packs which have been produced in any other ways, as well as for all types of packagings which have the functional features of the blister pack concept.

1. A) einem mit Durchlässen 3 versehenen, flächenförmigen Basiselement 4, das sich zur sicheren Fixierung des Etiketts auf der zu etikettierenden Verpackung eignet, dessen Durchlässe jeweils einer (Figur 1a) oder mehreren (Figur 1b) der zur Aufnahme des Packungsinhalts vorgesehenen Wannen der Verpackung zugeordnet sind,
   wobei die Mindestgröße der Durchlassöffnung so gewählt ist, daß der Durchtritt eines Einzelobjekts des Packungsinhalts möglich ist und
   die Maximalgröße der freien Öffnung der Durchlässe so gewählt ist, daß zwischen ihnen zumindest noch Stege stehen bleiben, die die sichere Fixierung des Basiselements auf der Abdeckungsfolie 6 (der "Abdeckungsseite") der Tiefziehfolie 7 gestatten, und
2. B) mehreren flächenförmigen Informationsträgern 5, die klappbar an dem Basiselement 4 befestigt sind, und wobei zur Befestigung des Basiselements (4) auf der Durchdrückpackung (2) das Basiselement (4) auf der Haftseite mit einem Haftmittel versehen ist.

An object of the invention is illustrative in the FIGS. 1a and 1b schematically and without scale illustrated multi-part label 1 for attaching information, in particular content-related information on blister packs 2 with respect to the packaging surfaces enlarged labeling surface, consisting of

1. A) provided with passages 3, sheet-like base element 4, which is suitable for secure fixation of the label on the package to be labeled, whose passages each one ( FIG. 1a ) or several ( FIG. 1b ) of the pans provided for receiving the contents of the package are associated with the packaging,
   wherein the minimum size of the passage opening is selected so that the passage of a single object of the contents of the package is possible and
   the maximum size of the free opening of the passages is chosen so that between them at least still remain webs that allow the secure fixing of the base member on the cover sheet 6 (the "cover side") of thermoforming film 7, and
2. B) a plurality of sheet-like information carriers 5, which are hingedly attached to the base member 4, and wherein the base member (4) is provided on the adhesive side with an adhesive for fixing the base member (4) on the blister pack (2).

The in the FIGS. 1a and 1b Rectangles shown in dashed lines on the push-through packs 2 mark the trough openings located below the covering film 6. In the FIGS. 1a and 1b one also recognizes the fields 20, if desired, which are present in preferred embodiments of the label according to the invention, on which label numbers and / or other indispensable information, eg about the package contents or via an encoding of the contents of the package. The FIG. 1b moreover shows an adhesive coating 8 with which the base element can be fixed on the cover side of the blister pack. The FIGS. 1a and 1b also illustrate the placement and fastening of the label 1 on the blister pack 2 by the downward arrows.

There are various design options for the passages in the base element. It is possible to form the passages as open apertures, which, as in FIG. 1a represented, single or, as in FIG. 1b represented, several troughs of blister pack are assigned. Here, when removing the product from the tub, only the thin cover sheet to break. The removal can therefore be done with a minimum of effort and the load of the product is identical to that when removed from an unlabeled blister pack. This form is therefore usually for pressure-sensitive goods, such as. relatively soft capsules, preferred.

The passages may also be designed as cross-shaped, meandering or star-shaped slits, as shown schematically and without scale in the FIGS. 2a to 2c are illustrated or they may be another appropriate, eg. have zigzag-shaped lines.

The FIG. 2a shows in oblique view a portion of a base member 4 with a trough of rectangular cross-section associated cross-shaped slot passage in the closed state 9a and in the open form 10a, as it exists after the removal of the tub contents. The cross-shaped solid lines in FIG. 9a show the course of the slots delimiting the small area elements 11; the dashed lines mark the crease lines along which the area elements 11 are bent when opening the passage.

The FIG. 2b shows in oblique view a portion of a base member 4 with a plurality of tubs associated meandering Schlitzdurchlaß in the closed state 9b and 10b in open form, as it exists after the removal of the tub contents. As in Fig. 2a marks the solid meandering line the Slot profile of the passage 9b, the dashed line marks the crease line along which the surface elements 11 are bent when opening the passage.

The Figure 2c shows in vertical plan view a fragment of a base element 4 with a circular cross section associated with a circular slot passage 9c. Of course, star-shaped slot openings can also be assigned to tanks which do not have a round cross-section.
The slots of the slot passages are preferably completely passed through the base material and define small surface elements 11 of the base material, which are still connected on one side with the main surface. As in the FIGS. 2a and 2b shown, the small surface elements 11 are bent when tearing the cover sheet in the removal of goods and thus give the required passage free. Similarly, notches that do not completely penetrate the base material, perforations, or other measures that weaken the material of the base element locally only to the extent that it can be torn open. These embodiments should also be understood by the term slot passage.

The advantage of slot apertures over open apertures is the increase in the area available for connecting the base material to the surface of the blister pack.

For attachment of a base element, which is not part of the package itself, on the blister pack is a fastener, hereinafter also referred to as an adhesive, which is symbolized in the figures by an adhesive layer 8. As adhesives, however, in principle all suitable for such a purpose means come into consideration. The choice of this adhesive is made according to the requirements of the practice, ie the durability requirements, the required strength of the adhesive bond, the long-term stability, the tolerable production cost of the label and the handling options for the user and the packaging designs.

The adhesive can be attached to the adhesive side of the base member, or the fixation can be done with separate commercially available fasteners or integrated with the packaging fasteners.

Separate, commercially available fastening means with which the base element can be fixed in a manner known per se on the packaging, for example, staples, rivets or adhesive. Adhesives that are part of the package may have the form of grooves into which a rigid base member may be inserted, may be elastic anchors that engage and snap into openings in the base member, or an adhesive layer applied to a package surface, e.g. be a contact adhesive layer. As adhesives that are part of the label according to the invention, for example, also elastic, hook-shaped anchors that snap into openings or edges of the packaging, or an adhesive layer into consideration.

Preferably, the base element is provided on the adhesion side or over the whole area with an adhesive layer, which is suitable for secure fixation of the label on the package to be labeled. Adhesives are those which can only be used after pretreatment, e.g. after moistening with a liquid, water or a solvent, unfold their adhesive power, or even those that adhere readily on a possibly pretreated surface of the packaging.

Adhesive layers which adhere directly, hereinafter referred to as a contact adhesive layer, are expediently covered with a peelable protective film in order to avoid unintentional adhesion of the label to devices and other objects.

Another way to fix the base member on a surface of the package results when this surface and the base member made of a thermoplastic material. In this case, the base element with the said surface of the package can be welded over the entire surface or punctiform.

The surface size and shape of the base element are based on the dimensions of the surfaces available on the packaging and suitable for affixing the label. Unless it is desired, for particular reasons to be described below, that the base member has an overhang at one or two edges of the package (cf. Figures 3 . 4b . 5a, 5b . 6 , No. 12), it is preferably dimensioned so that it does not protrude at the intended area for attachment, but flush with the edges of the package or covers only a portion of the surface. Although a maximum of the adhesive force can be obtained when the label covers an entire area of the package, especially the largest area, special conditions may exist under which partial coverage is sufficient or preferred.

While it is thus often convenient that the size and shape of the base member correspond to the size and shape of the packaging surface to be labeled, it is sometimes more advantageous to deviate therefrom. Thus, it may be advantageous if the base element, the packaging surface to be fixed to it, forming an overhang surface 12, surmounted. Such an overhang can, as explained below and in the Figures 3 . 5a . 5b . 6a, 6b and 7 illustrated, be advantageous for a particular design of the label according to the invention or for the attachment of the information carrier to the base member.

The base element, which mediates the connection of the label according to the invention to the blister pack, can - as in FIG. 1 shown - are fixed on the cover sheet 6 of the blister pack, but it can also be on the deep-drawn side, the "tub side" 7, fixed. In the latter case, the passages are arranged and dimensioned so that the trays can be passed through them. The webs between the passages are then fixed to the existing between the troughs substantially flat surface areas of the thermoforming sheet. Such an arrangement, in which the base element 4, for example by means of an adhesive layer 8, is fixed on the deep-drawn side 7a of the blister pack 2, show the FIG. 3 and the FIG. 3a which is an enlargement of the circled part (K) of FIG. 3 represents ,. In this exemplary illustration, the information carriers 5 are fastened (hinged) to an overhang 12 of the base element 4 via a spiral 13 to be seen as a circle and can be deposited on the cover film 6 as a stack. The in the FIG. 3a shown magnification clearly shows that in this Construction present layer sequence (from bottom to top): Base element 4, adhesive layer 8, thermoforming film 7 and cover 6.

With such a construction, the removal of the contents of the package is naturally hindered by the base element in any way when folded up information carrier stack.

But even if the base member is fixed on the cover side of the blister pack, the removal of the packaged objects must be possible. The passages must therefore open at least to the size that the objects can pass them. For spherical objects, this means that the passage can be opened at least to the size of the object diameter. For non-spherical objects, the required passage opening depends on the position of the objects to the cover. The optimal position of the objects would be that in which their projection on the cover forms the smallest possible area. Passages in the base element, which have this free opening or can be opened on this free opening, then in principle sufficient to remove the objects from the tubs.

However, this presupposes that a non-spherical object - and these are the majority of the packaged objects - is first rotated in the tub in the optimal removal position. This means a more difficult removal and in some cases is not possible.

If it is desired to allow a substantially unobstructed passage of an individual object of the contents of the package, the cross section to which the passages can be opened expediently corresponds essentially to the largest cross section of the goods to be removed.

Even with this dimensioning, it may occasionally come to a snagging or tilting of the objects at the edges of the passages. This can be avoided if the cross section of the free opening of the passages corresponds to the largest internal cross section of the trays of the package.

On the cover side, a base member is mounted so that cover its passages with one or more covered with push-through film vents so far that a removal of the packaged goods is possible.

The hinged on the base element (hinged) information carrier are sheet-like blanks whose intended for receiving the information surface in shape and size appropriately corresponds to the dimensions of the packaging to be labeled packaging surface, and thus usually those of the base element. Unless the information carriers 5 are to be fastened to an edge of the base element 4, they point beyond the information area into which FIGS. 4a, 4b . 5a, and 5b denoted by the numeral 14, a designated with the numeral 15b mounting area, between which, if necessary, symbolized by small circles flexible connection 16 is.

The information surfaces of the information carrier can, if desired, be prepared for example by generating writable, printable, reflective or magnetizable or otherwise suitable for storage and / or visualization of data surfaces for recording corresponding, and optoelectronic, information, or they can attach a the Information-containing label to be prepared. Finally, they may themselves be provided with an optionally film-protected adhesive layer, which allows any information-bearing labels that have no gum and no contact adhesive to attach to the information surfaces of the information carrier.

In the same way, the remaining between the passages webs of the base elements can be prepared for information recording.

An edge of the base element or a partial surface of the base element which does not lie over trough openings and therefore does not have to have openings to be opened or open openings, hereinafter referred to as attachment surface, can serve for fastening the information carriers.

The mounting surface of the base member usually occupies only a small portion of the base member surface, which is suitably parallel to an edge, preferably a short edge, of the base member.

In a blister pack in which the thermoforming sheet has been deformed into trough-shaped depressions only on a part of its surface, the fastening area of the base element can lie above the non-deep-drawn surface of the thermoforming sheet. Blister packs of this type are used for special cases where, for example, despite the use of a standard thermoforming tool only a small number of wells is desired, so that an undeformed surface area of the film remains. The FIG. 4a illustrates schematically in the manner of an exploded view in side elevation schematically and without scale a blister pack 2 consisting of thermoforming film 7 in which only a partial area was deformed into trays, and the covering film 6 attached over it, covering the entire surface of thermoforming film in this example, but the Of course, just above the tub area could be appropriate. On the cover film 6, the base element 4 of the label according to the invention is fixed by means of the adhesive layer 8, which likewise covers the entire surface of the deep-drawing film in this exemplary illustration. The attachment surface 15a of the base element lies above the undeformed part of the thermoforming sheet 7. The size of the base element shown here is not mandatory. It could also be smaller than the surface of the thermoforming foil, as long as its surface is sufficient to provide the necessary information and to give the label on the package a secure fit.

The information carrier 5 shown above the base member are positioned so that they meet when lowering in the direction of arrow with their mounting surfaces 15b on the mounting surface 15a and there by means of a fastener, in the FIG. 5 symbolized by the bracket 17 can be mounted on the base element.

In a blister pack, in which the entire surface of the thermoforming sheet has trough-shaped deformations, an overhang of the base element, the over the packaging surface to which the label is to be attached extends, be used as a mounting surface. The overhang may conveniently be a continuation of a base member which has been cut so that only a portion of its surface is for attachment to the blister pack and provided with apertures. The FIG. 5a illustrates, also in the manner of an exploded view, in schematic plan view and without scale a blister pack 2 consisting of thermoforming film 7 in which the entire, available area was deformed into trays, and the cover film attached over 6. On the cover film 6 is by means of the adhesive layer 8 fixes the base element 4 of the label according to the invention, which has the overhang 12 extending beyond the surface of the deep-drawing film. The attachment surface 15a of the base member is here on the overhang 12. Also in this embodiment, the illustrated size of the base member is not mandatory. It could also be smaller than the surface of the thermoforming sheet, as long as its area is sufficient to provide the necessary information and to give the label on the package a secure fit.

The information carrier 5 shown above the base member are positioned so that they meet when lowering in the direction of arrow with their mounting surfaces 15b on the mounting surface 15a and there by means of a fastener, in the FIG. 5 symbolized by the bracket 17 can be mounted on the base element.
In the FIGS. 4a, 4b . 5a and 5b are also the information areas 14 of the information carrier shown. Between these and the attachment surfaces 15b are linear flexibilized zones, symbolized by the small circles 16, which allow the unfolding of the information carrier.

The FIGS. 4b and 5b illustrate by joining and joining in the FIGS. 4a and 5a shown information carrier 5 with the base elements 4 resulting labels 1 according to the invention.

Of course, the different ways of attaching the information carrier on the base element - completely independent of the manufacturing process of the package - always selected appropriately with respect to their design.

For the attachment of the information carrier to the overhang surface of the base element, there are further different possibilities. The FIG. 6a shows in side elevation schematically an embodiment of the label according to the invention, in which the information carrier 5 are fixed in the manner of a book binding to the overhang 12 of the base member 4 and the base member is provided with an adhesive layer 8. The information carrier stack then results from the superimposed, centrally folded information carrier strips. It is particularly advantageous in this type of attachment when the overhang has a particularly high flexibility, because then the information carrier can be particularly easy to open (see FIG. 6b ).

Occasionally it may be beneficial if, as it is in FIG. 7 is shown schematically in lateral view, the information carrier 5 are placed on the side of the tub of blister pack 2, which is the opposite of the base member 4 side. This structure can be made possible if the length of the overhang surface 12 corresponds to the sum of the height of the packaging and the width of the attachment surface 15. The attachment surface of the base element then expediently lies at the end of the overhang surface projecting beyond the packaging surface.

The connection between the base element and the information carriers can take place in various ways. Thus, it is possible, the mounting surfaces of the information carrier with the mounting surface of the base member by any known, effective between them fasteners - in the FIGS. 4a, 4b . 5a and 5b symbolized by the bracket 17 - rigidly connect and articulate the information surfaces of the information carrier at their attachment surfaces hinged.

This means that in this type of attachment of the information carrier to the base member between the mounting surfaces 15b of the information carrier and their information surfaces 14, the flexible connection 16 must exist.

If there is little need for information, only one information carrier can be fastened on the base element. Such a single information carrier can very easily also be formed from an extension of the base element folded back on a flexible bend line.

In general, however, the considerable advantages of the label according to the invention only come into full effect when a great deal of information must be given which has no place on a single information carrier.

As a rule, therefore, a multiplicity N of information carriers are connected to the base element. As a rule, 5 to 30 information carriers are mounted on a base element (N = 5 to 30). Depending on the current space requirement, N can also be smaller or larger. The N information carriers are then fixed as a stack with superimposed attachment surfaces on the attachment region of the base element.

The feature statement that the information carrier are attached to the base member, of course, includes such stacked information carrier in which only the lowest information carrier bound directly to the base member, all overlying are indirectly attached via the intermediate information carrier layers to the base member. It also includes the in FIG. 6a illustrated embodiment of the label according to the invention, are attached to the centrally folded information carrier strips in the manner of a book binding to an overhang of the base member. The information carrier stack then results from the superimposed, centrally folded information carrier strips.

The attachment between the mounting surfaces of the information carrier and the mounting surface of the base member can be done with all known fasteners. As preferred, known mechanical fastening means may serve one or more brackets or rivets, with which the mounting surfaces of the stacked information carrier are attached to each other and to the base member. Another preferred type of mechanical attachment can be done by sewing, where monofilament or multifilament threads or metal wires can serve as a suture. However, it is also possible as an attachment means an adhesive, preferably to use a contact adhesive, with which the mounting surfaces of the stacked information carrier are glued to each other and to the base member. For example, information carriers which are provided on the mounting surface with a, possibly foil-protected, adhesive coating are particularly advantageous. Depending on the machine manufacturer of the label maker, such a material may offer advantages in the production of an information carrier stack on the mounting area of the base member.

The free edges of the attachment surfaces may be adhesively bonded together to provide additional, e.g. for stapling, to provide a higher strength and to minimize the peeling of the attachment area.

The information carrier stack may also be formed by a zigzag folded strip of information carrier material secured to an edge or to the mounting area of the base member. Particular, described below advantages arise when the zigzag folded strip is a folded back, strip-shaped extension of the base member.

Particularly useful, uncomplicated and advantageous is the hinged attachment of the information carrier to an edge of the base member or an edge of an overhang of the base member. Choosing the width of the overhang as large as the thickness of the package, so there is the above-mentioned advantage that the information carrier stack can be stored on the side of the blister pack. The attachment to the edge is advantageously carried out in the form that the first, lowermost information carrier directly to the base member 4 or an overhang of the base member, each further, overlying information carrier 5 then attached to the previous (hinged) is. The FIGS. 8 and 9 illustrate in a lateral view that this can be achieved in two different ways: The higher-lying information carriers can each be attached to the edge of the underlying information carrier with this attached to its predecessor or to the base member ( FIG. 8 ) or the higher lying information carriers can each be articulated on the free edge of the predecessor ( FIG. 9 ). The flexible attachment (linkage) is also in the FIGS. 8 and 9 symbolized by the circles 16. This type of attachment is most easily realized by cutting out the base member and the information carriers from a continuous strip of suitable sheet material of sufficient strength. The width of the strip corresponds to the width of the package, the length is expediently a whole multiple of the package length and, if desired, a length addition in size of the package thickness. The FIG. 10a Figure 4 illustrates in vertical plan view a portion of such a strip and the treatment of the strip described below. A portion of this strip, usually the first, is provided with the passages 3 required for the base element, for example by punching or notching. At the end of the base element, the strip is aligned on a line transverse to the longitudinal direction - in the FIG. 10a represented by the dashed line 18a - flexibilized by suitable measures, so that it can be folded in this line against the base member. Subsequently, a flexible transverse line (dashed lines 18b) is generated at intervals of the package length, so that a multiplicity of information carrier surfaces are formed. If one wishes a distance 19 in the size of the packing thickness between the base member and the information carrier stack is, as in FIG. 10b 12, the strip additionally flexes at this distance 19 from the line 18a at 18c across its length, and thereafter, as described above, the flexible transverse lines 18b follow.

Subsequently, the information carrier surfaces can be folded in a zigzag folding to an information carrier stack, wherein the embodiment of the FIG. 9 receives, or it can be glued two consecutive information carrier sections with the facing surfaces, wherein the embodiment of the FIG. 8 is obtained. The embodiment of the FIG. 8 is particularly handy and also particularly robust due to the laminating of two material layers. If a section in the length of the packaging thickness has been switched on between the base element and the first information carrier surface, then the information carrier stack can be deposited on the side of the tub ( FIG. 7 Otherwise, deposit it on the cover side. The inscription must be adapted accordingly.

Alternatively, but technically considerably more expensive, can as fastening means one or more, fixed in the base member or integrated and in edge holes in the Attachment surfaces of the information carrier engaging eyelets, in which the information carrier can be turned in the manner of ring binder pages. Similarly, as a fastener mounted in the base member and engaging in edge holes in the mounting surfaces of the information carrier spiral can be used in which the information carrier can be turned in the manner of spiral pages pages.

In this type of attachment no flexible connection between the mounting surfaces and the information surfaces of the information carrier is required.

The base member may also be part of the blister pack 2 itself. In principle, both the thermoforming film, in which the trough-shaped depressions are formed, as well as the cover film take over the function of the base element. For the attachment of the information carrier, an extension of the film material corresponding to the overhang of a base element can be provided both on the thermoforming film and on the cover film, on which the information carriers are fixed with their attachment surfaces in one of the manners described above. The FIG. 11 schematically illustrates a formed from the thermoforming sheet 7 of the blister pack 2 base member 4, on the overhang 12, the information carrier 5 are fixed by means of adhesive layers 8. The trough openings are closed by the cover 6.

In an analogous manner, the cover 6 - if necessary, after reinforcement of the mounting surface or the overhang - can be used as a base element. It goes without saying that in this case the base element must not have any passages

The information carrier need not be mounted on an overhang of the thermoforming sheet or the cover sheet, but may also be attached (hinged) to one edge of the sheets. The hinging on one edge can be performed in the same way as described above for separate base elements. It is also particularly advantageous here if the information carriers are formed from a continuation of the thermoforming or covering film folded in zigzag fashion. The information area of the information carriers can, as described above for separate basic elements, if desired be prepared for the reception of corresponding information, or it may be provided with a glue-friendly surface for applying a self-adhesive label containing the information.

The part of the packaging material intended as a fastening surface may be prepared, as described above, by an adhesive coating for the gluing of one or a stack of information carriers. Also, the other types of mounting the information carrier stack described above, such as riveting clips or stitching, are practicable. If necessary, in particular if the covering film is to perform the function of the base element, the tear resistance, in particular the tearing, tear and tear propagation resistance, can be determined, for example. by applying resin or backing with nonwovens, foils or paperboard to increase the strength of the connection of the attachment area to the information carrier package.

As with the base element, it is generally expedient if the size of the information surfaces of the information carrier corresponds to the size of the packaging surface on which the label according to the invention is fixed. The mounting surface is tuned in the individual case on the type of attachment and on the size of the present on the base element mounting surface. The choice between the various design and construction options is made according to appropriateness criteria in each case.

The base element and the information carrier can in principle consist of the same or different known, sheet-like materials. The choice of material depends on the functions that are attributable to the components of the label and the required mechanical strength, for example, the required tear resistance and aging resistance. A special requirement of the material of the base member is that it is suitable for the production of solid and permanent adhesive bonds with packaging materials, but that it also between the passages for labeling or other information storage, eg by printing, embossing, punching, baking, preferably for printing or sticking with labeled labels is suitable. The same applies to the material of the information carrier. This one must on the one hand a allow proper attachment to the base member, on the other hand to a simple permanent information storage on both sides of the information surface are suitable.

Last but not least, the materials should allow for easy manufacture and the material price should not be prohibitive.
Materials from which the base elements and the information carriers may consist are, for example, paper, cardboard, in particular those with synthetic resin or long fiber reinforcement, nonwoven material, in particular resin-bonded or autogenously bonded spunbonded nonwovens, plastic film, metal foil or composites of two or more of these materials.

If the base element and / or the information carriers consist of a single-layer material, occasionally not all requirements, e.g. in terms of stability and information storage capacity are met to the maximum extent but a compromise between the individual requirements is required. Nevertheless, it is usually possible to meet the requirements that can reasonably be imposed on a label according to the invention even with a single-layered material.

For higher demands or for special embodiments of the label according to the invention, it is advantageous if the base element and / or the information carrier consist of a multilayer material. Thus, for example, by combining various materials for a base layer, a storage layer, an adhesive layer and / or a protective layer particular advantages for the production and application of the labels can be achieved.
As an example, an information carrier may be mentioned, consisting of a one-sided or double-sided self-adhesive material coated with a peelable protective film.

On such an information carrier labels can be pasted after removal of the protective film of the information surfaces, which themselves must have no adhesive surface. Subsequently, the protective films can be removed in the attachment area prior to collation, and the information carrier can be glued to the stack. Such a material therefore leads to a rationalization of the production of the multi-part labels according to the invention. Another example is a base element that has an overhang has, on, as in FIG. 5a shown, a variety of information carriers are attached, and stiffened in the adhesion and information area, for example, resin-reinforced, and is highly flexible in the overhang area. By such a combination of materials is the paging of the information carrier, as in FIG. 5b presented, greatly relieved.

A material that is particularly good for making the in FIG. 8 illustrated, preferred embodiment of the label according to the invention, is a sheet, for example of paper, foil or nonwoven fabric that at least one side coated with an adhesive - and if it is a contact adhesive, covered with a peelable protective film - is. A strip of such a material can be provided with kinks in the area provided as a base member with passages on the remaining length at a distance from the information carrier length. The protective films are then removed from the adhesive for the strip length provided for information carriers, and in each case two successive glued together with the adhesive surfaces. This gives an extremely rational way according to the invention a label according to FIG. 8 ,

The information can be applied later or before removing the adhesive protective film. Alternatively, a material can be used which is adhesive coated on both sides. With one side one moves, as described above, from the other side of the protective films are only removed when labels are to be glued with the information on the information carrier. You can use in this case labels that have no adhesive application.

An essential feature of the labels according to the invention is that the information carrier attached to the base element hinged (hinged). Unless the attachment, as described above inter alia, via a flexible connection of an edge of the information carrier with an edge of the base member or an edge of the preceding information carrier takes place, or by eyelets or spirals, which engage in a corresponding hole of the mounting portion of the information carrier is accomplished , is between the mounting surface and the information surface of the information carrier a connection is required, which allows the paging of the information carrier, ie, which allows to set an arbitrarily small angle between the two surfaces. This change in angle should be able to take place within as short a distance as possible, so that the entire information surface of the information carrier can be viewed when it is opened, so that the information can be read without difficulty. In the simplest, the preferred case, the information carrier is made of such a flexible material, such as paper or nonwoven fabric, that the paging of the information carrier stack can be done without difficulty, as in a book. In a narrow area between the mounting surface and the information surface of the information carrier then forms a more or less sharp bend or crease line when flipping easily, which allows to overlook the entire information surface. Special measures that allow the setting of a required for unhindered flipping angle between the mounting and the information surface, are not required in this case.

On the other hand, if the information carriers of an information carrier stack consist of materials that are inherently less flexible, e.g. Cardboard or resin-reinforced papers, such a simple construction is no longer possible because when trying to open the information carrier stack, too large a radius of curvature forms in the information surfaces, which makes reading the information very difficult or impossible, or cracks or Fractures in the information carriers, which can also lead to a loss of important information. Therefore, in this case constructive measures are to be taken, by which it is possible, despite the stiffness of the material required for the paging angle between the mounting and information surfaces of the information carrier set, the curvature of the material on a short, strip-like section between Fixing and information surface to be made.

The requirement is in principle to be met by any known, working in a jam-like construction. An expedient practicable and cost-acceptable solution is that a narrow area of particularly high flexibility is provided on the straight boundary line between surfaces which have to be inclined against each other, which the required flexible connection between the surfaces guaranteed. A prerequisite for this is that the flexible connection is made by a link of a fatigue-resistant flexible material.

For example, the flexible connection between the surfaces can be made by fibers extending between them and firmly bound into them. These may be fibers of the fiber material from which the information carrier and the base element are made, or they may be reinforcing fibers which are inextricably worked into the sheet material at least in the region of the bending line.

If the mutually inclined surfaces consist of a coherent piece of a suitable material, the flexible connection can be formed by a fatigue bendable line between the sub-areas of the material. Such a pre-planned bending line can be achieved by a targeted change in the material structure, which leads to an increase in flexibility and is limited to the narrow bend region. For example, the bending line can be preformed by repeatedly bending the material on the planned line.

However, the targeted increase in flexibility can also be achieved by a linear reduction in the thickness of the material created by scratching, for example, or by reducing the mass of material lying on the crease line by linear perforation.

If the material consists of two or more layers of different flexibility, the layers of lesser flexibility may be slit or perforated at the intended crease line.

Information can, as in FIG. 12 represented on the label according to the invention both on a sufficiently wide web 20 between the passages 3 of the base member 4 and on both sides of the information area 14 of the information carrier 5 are attached.

Preferably, a field 20 for a label identification mark is reserved both on the base element and on the top of the uppermost information carrier. It is also possible to reserve a label tag field on each information carrier page. Such a mark enables error-free, even automatic labeling of packages which have the same identification mark. The identification sign may e.g. a letter and / or number combination or even a unique, possibly even of machines, be identifiable icon.

If possible, indispensable basic and security information, in particular identification information, is placed on the webs of the base element in addition to the label identification in an easily readable world language.

Preferably, this indispensable basic information is also still attached to the top of the top, mounted on the base element (articulated) information carrier.

In view of the prevalence of the English language and its easy readability, it is preferable to provide the basic and identifying information in that language.

All desired information may be printed on the information surfaces of the multi-part label according to the invention by writing, printing, embossing, punching, or plain-writing or in the form of digital-optical information, e.g. Barcode to be applied, or base element and information carrier can be pasted on the information surfaces with labels 21 on which the information mentioned are listed. If the information carriers have film-protected adhesive-coated information surfaces, adhesive-free labels can be used, otherwise adhesive labels are used.

On surfaces that are prepared for magnetic information storage, the information can also be stored magnetically. With a suitable choice of Carrier material can also be done simultaneously a magnetic and printed reprinting of the information on the information carrier.

The large amount of space on the label according to the invention makes it possible to store all the required and / or desired information sorted in the desired manner. It is thus possible to provide the individual information carriers with country-specific information. The finding of such sorted information is particularly facilitated if a register 22 is cut on at least one edge of the information carrier stack. The other edges, in particular the second longitudinal edge of the information carrier stack may also have a register. This is particularly advantageous if, for example, carry the front pages of the information carrier country-specific ordered information, the backs, however, have a factual sorting of this information. You can then search in one tab country-related, in the other search subject-specific. Another way to search specifically for different criteria is to provide a tab bar, which is printed differently on the front and the back according to the different sorts.

A register may also be obtained by having information carriers having different order characteristics having a different length or width, while all information carriers having the same ordering characteristics have substantially the same dimensions. The differences in dimensions are chosen so that the resulting levels for recording the keywords or content specifications are sufficient.

If the size of the information carrier allows it, the order to a regulatory feature, for. B. a specific language belonging information carrier also be graded again in length, or even on another page carry a register, so that within a stack of information carriers that are assigned to a particular order feature, again a fine division takes place. In principle, this subdivision procedure should continue until the resulting stages are no longer sufficient to record index information in a recognizable form.

However, indexing by no means necessarily takes place in plain text, but other indexing options can also be used, such as e.g. the application of a color code or the use of information carriers of different colors.

Other known search aids can be applied to the information carrier stack, such as e.g. colored edge markers together with a mounted on the cover sheet or the base element index or groove-shaped edge cutouts, in the stack, coming from above on a belonging to a certain keyword information carrier and there reveal the keyword in question.

The FIG. 12 further shows a combination of adhesive layers 8 and brackets 17, through which the information carriers are fixed on the base element in the attachment region 15. Of course, all known fasteners, including those in the FIG. 12 8 and 17, individually or, if advantageous, in any combination with each other.

The FIG. 13 exemplified in an exploded view in side elevation schematically another particularly expedient embodiment of the label according to the invention. It has certain important variable data, such as patient numbers, batch designations, usability date and the like, on a partial surface 24 of the base element 4 which is free of cross-slit passages 3.

Above the base element shows the FIG. 13 three information carrier stack 5a, 5b, 5c, which result in a stack with a register strip due to different length when lowering in the arrow direction on the base element. Each of the three stacks contains information in a language assigned to it. All information carriers have a window-shaped opening 23 which, when stacked, results in a viewing window extending through to the base element, through which the data field 24 of the base element is visible. At least the uppermost sheet of each of the three stacks has near the window opening 23 a reserved field 25 on which the meaning of the data indicated on the field 24 in the language associated with this stack is indicated. To form the label according to the invention, the parts 5a, 5b and 5c on the base member 4th lowered and the ensemble in the region of the mounting surfaces 15a and 15b firmly connected.

This embodiment has the advantage that in the fields 25 of all information carrier fixed standard information can be, and the variable information (patient or batch numbers and the like) must be noted only once on the field 24 of the base element. This construction not only facilitates the production of the labels but also avoids sources of error and errors. It thus makes a further significant contribution to the safety of medicaments, e.g. in clinical trials.

In the in FIG. 13 As shown, the field 24 is in a surface region of the base member 4, in which there are no passages. This representation is particularly well suited to clarifying the principle of this construction. Such an embodiment is realized when no troughs or filled troughs are provided in the blister pack to be labeled under the non-apertured surface of the base member. If the base element is completely filled with passages, then the information field 24 will, if desired, be located on a surface lying between or next to the passages, for example in the region of the in FIG. 12 shown information field 20, attached. The window openings in the information carrier stack are positioned accordingly.

In a further preferred embodiment, at least one of the information carrier is designed so that it can be removed in whole or in part, if necessary, in several sections from the information carrier stack. Preferably, the uppermost information carrier of the stack is selected for this embodiment. Here, the design of this information carrier is done so that the complete or partial removal from the stack can not be done unintentionally, but only by purposeful, planned action. Embodiments which fulfill this purpose are known per se. For example, the information carrier can be perforated or scored on certain lines, which can also be wavy, or it can be otherwise prepared in the lines provided for the separation, for example by deliberately reducing the tear strength of the material for the removal of the sections. If the information carrier is to be removed altogether from the stack, perforation or scribe lines can be placed, for example, around a clip that is seated in the fastening surface. Thereby, the information carrier can be removed together with the non-clamped part of the mounting surface of the stack, while the part held by the clip of the mounting surface remains on the stack. Similarly, in a stack adhered to each other, the information carrier may be divided into attachment surface and information surface by perforated or scored dividing lines. Of course, the measures that allow partial or complete targeted separation of an information carrier from the stack can also be used in combination.

In a further embodiment of this embodiment, the separable information carrier or parts thereof are such that they can be fixed on other surfaces. For example, these information carriers can have a self-adhesive layer protected by a release film on the side opposite the information, or they can be provided with a water-activatable rubber coating.

In yet a further embodiment of the label according to the invention, one or more information carriers of the stack, preferably the uppermost one, are designed so that one or more partial surfaces thereof can be separated from the composite, which are located at arbitrary locations of the information carrier and can have any desired shapes. The separable faces are by boundary lines or curves on which the material of the information carrier is weakened by known measures so that the faces along these boundary lines can be separated from each other and / or from the remainder of the information carrier remaining in the label composite or they are by the edges limited to the information carrier. The known measures, which serve to weaken the material along the boundary lines, are chosen according to the nature of the boundary and the shape of the portion to be separated appropriately. Known suitable measures are, for example, the scoring (notches) or perforation, the perforation holes can also be slots (slots), between which only selective connections between the separable and remaining in the label composite part of the information carrier remain. If the shape and position of the surface elements to be separated permit, material fatigue can also be provoked, for example, by buckling along a boundary line, which enables separation of the section along this line. Furthermore, it is possible to slit the carrier material over a partial length of the boundary line continuously through the entire material thickness and only the non-slotted part of the boundary, by which the separable portion is still connected to the part remaining in the composite information carrier, in the manner described for the To prepare the demolition.

Particularly advantageous is a sheet-like information carrier from which one or more information-bearing partial surfaces are separable, which are located at arbitrary locations of the information carrier and may have any shapes and which can be adhered after separation on other surfaces, consisting of a sheet-like, at least three-layer material, wherein the lower layer is an adhesive-repellent layer. Adhesive-repellent or adhesive-repellent material is here referred to, on which an adhesive layer indeed adheres, but the adhesive bond can be separated again without significant damage to the layers, with a lying within a predetermined range of separation force is spent. Adhesive repellents are so-called smooth layers such as e.g. a silicone paper layer. Adjacent to the adhesive-repellent layer is an adhesive layer and overlying at least one information-carrying adhesive-friendly layer. In such an information carrier can then be separated a section to be prepared by an appropriate double notch along at least one boundary so that when it is separated from the information carrier along this boundary line a free adhesive strip remains on the severed portion.

To carry out such a double notch, the information carrier is notched from both sides by spaced notches such that the one notch 28a extends directly on the intended boundary line from the top through the information-carrying layer (s) and the adhesive layer to the adhesive-repellent layer is guided, the second notch 28b, preferably substantially parallel to the first, from the bottom only cuts the adhesive repellent layer, and that the two, Notches have a predetermined distance A from each other. In this case, the guided from above notch on the intended boundary line, which is guided from below, however, is displaced by the distance A to the center of the surface element to be separated. The Figure 14a illustrates, for example, without scale a cross section through a portion of a three-layer information carrier 30, which is provided with such a double notch. It can be seen in this figure, the information-carrying layer 26 which is connected via the adhesive layer 8 with the adhesive-repellent layer 27, the two spaced notches 28a and 28b and the bracket 17, with which the information carrier is attached to the labeled package.

If such a prepared section of an information carrier is charged, it will, as in the FIG. 14b is shown separated at the notches in the two parts 30a and 30b so that the separated portion 30b is provided at the double notched separating edge with a free adhesive strip 29 of the width A, with which one can stick it on another surface if desired ,

For example, such a measure may increase the safety of clinical trials, facilitate documentation for the treating physician, or provide reliable information about the drug to the patient.

The in the Figures 14a and 14b Of course, shown bracket can also be replaced by another fastener. Such an information carrier provided with the described double notch can also be attached to containers to be labeled independently of the multi-part label according to the invention described above in any manner known per se. Therefore, it is also an inventive element of the present invention.

Furthermore, it is possible to provide one or more information carriers of the stack, preferably the uppermost one, with one or more information-bearing labels which can be completely or partially removed from the information carrier. This can be made possible, for example, in a manner known per se, by providing at least the part of the label intended for removal - optionally perforated or pre-scored Dividing lines can be separated from the rest of the label - rests on a surface of the information carrier, which is provided with a dehäsiven coating. The label then sticks in these places so that it is not separated unintentionally, but targeted and effort a not too small force can be deducted from the information carrier. You can facilitate peeling, if you provide on one side or corner of the label or label part to be removed an adhesive-free handle bar or tab. Furthermore, it is possible, for example, to glue the labels on only part of the area on the information carrier and between the glued and the non-glued part one, or if necessary, provide multiple tear lines that allow it to tear off the non-glued label part. Of course, other known measures that meet the desired purpose can be used. Combinations of these measures can also be used for the purposeful design of the label according to the invention. There is also the possibility of applying the information present on the tear-off label on the surface which is covered by the tear-off label before being torn off.

In a further preferred embodiment, the label according to the invention has a tumbler which prevents the hingedly mounted information carriers from unfolding, i. which can hold the label in a closed state. Such tumbler can be realized in various ways.

In the simplest case, the uppermost information carrier can have an appendage projecting beyond the label size, which is completely or partially coated on its underside with an adhesive adhesive and optionally has a gripping bottle which is not coated with adhesive. This extension can be pressed in the closed state of the label on the surface of the package and then results in a detachable connection between the uppermost information carrier and the packaging, by which the unintentional opening of the label is prevented. Conveniently, the affinity of the adhesive is matched to the material of the package so that the required adhesion force is given, but when separating the bond, the surface of the package is not damaged. In this way it can be achieved that the adhesive surface can be opened and closed several times.

The force required to release the closure can be adjusted by the size of the adhesive surface. For example, the width of the extension may be smaller than the width of the uppermost information carrier or the extension may have a hole punching, by which the adhesive area is reduced.

A further possibility for realizing a tumbler may consist, for example, of a reversibly stretchable thread or band (for example rubber band) attached to two points spaced from the fastening area of two different edges of the base element, which can be pulled over the information carrier stack.

In another embodiment, either from the base element or from one of the lowermost, preferably the lowermost, information carriers of the stack, at least one edge spaced from the attachment region, preferably at the edge opposite the attachment region, assumes a flexible extension which, by bending with the uppermost one Information carrier or with a suitably positioned extension of the same can be overlapped. In the overlap region, the overlapping parts are designed so that they form a tumbler in cooperation.

Such a tumbler can be designed purely mechanical. For example, one of the tumblers may be formed as a tab, button, or otherwise as a male part of a plug-in connection which may be inserted into an opening, e.g. a slot or otherwise formed as a female part of a connector part of the other tumbler element can be introduced, wherein during insertion the elements of the connector, a more or less strong elastic reversible deformation are subjected, which is reset after the complete union of the elements and thus establishes a firm but detachable connection.

The tumbler elements can also carry adhesive surfaces, at least in the overlapping area, which cooperatively effect a fixed but detachable connection and which are positioned so that they come to lie against one another when the flexible extension starting from the base element or one of the lower information carriers is connected to the uppermost one Information carrier or its extension is brought into contact.

Suitable adhesive pairings are for example a contact adhesive surface combined with an adhesive-repellent smooth-layer surface or the elements of a hook-and-loop fastener, namely a hooked and looped surface.

If the closure is effected by a contact adhesive surface in cooperation with an adhesive-repellent surface, it is expedient to provide an extension on the base element or one of the lower, preferably the lowermost, information carrier and possibly also on one of the uppermost, preferably the uppermost, information carrier. The outgoing from the base member or one of the lower information carrier extension is so long that it, upwardly bent with one of the upper, preferably the uppermost, information carrier or with a downwardly bent extension thereof overlaps. In the overlapping area, one of the overlapping elements is provided with an adhesive layer on the surface coming into contact with the other element, and the other element is provided with an adhesive-repellent smooth surface at the corresponding point. For reversible sealing, the closure elements are bent together, brought into contact with the functional surfaces and compressed.

This embodiment allows two possibilities of label closure: If the extension of the base element, so when closing the entire information carrier stack is firmly fixed on the package. If, on the other hand, the extension leaves from one of the lower, preferably the lowermost, information carrier, the information carrier stack can be opened up as a package after the closure of the closure, so that the base element becomes accessible. This has the advantage, for example, that it is possible to remove goods from the blister pack, e.g. Tablets, capsules or the like, without having to open the label.

In a special, production-friendly embodiment, a closure extension originating from the base element can be realized as follows:

From a laminated on one side with silicone paper or an analog adhesive-repellent material, a blank is made in the size of the adhesive portion of the base member having the required closure extension. Then, the interior of this blank is punched so that the apertured surface of the base member is exposed, so that a frame 31 is formed, on which the closure extension 32 is seated. This frame is placed with the adhesive-friendly surface on the base element and fixed so. The glued frame leaves most of the adhesive surface of the base element free, so that it can still be fixed reliably on the package.

The FIG. 15a Illustrates in a plan view obliquely from below schematically without scale such an embodiment of the multi-part label according to the invention. It shows the fixed to a base member 4 by the adhesive layer 8 frame 31 and the adjoining extension 32, which has on the visible surface in the drawing, the silicone paper layer, and the extension 33, which placed with its adhesive layer 34 on the extension 32 is, wherein the adhesive layer 34 of the silicone side of the extension 32 comes to rest. The lying below the adhesive layer 8 Kreuzschlitzdurchlässe 3 are shown dotted in the figure.

The FIG. 15b shows in a plan view obliquely from below schematically without scale a closable embodiment of the label according to the invention, in which the closure extension 32 does not start from the base element but from the bottom information carrier 5.

Multi-part labels according to the invention which have a plurality of the above-mentioned preferred features are particularly preferred.

An object of the invention is also a method for producing the multi-part label according to the invention. In a preferred manufacturing method, the base member and the information carriers are cut from a continuous strip of suitable sheet material of sufficient strength. The width of the strip corresponds to the width of the package, the length is expediently a whole multiple of the package length and, if desired, a length addition in size of the package thickness. The FIG. 10a illustrates such a strip and the treatment of the strip described below. A portion of this strip, usually the first, is provided, for example by punching, with the passages required for the base element. At the end of the base element, the strip is positioned on a line transverse to the longitudinal direction - in the Figures 10a and 10b represented by the dashed line 18a - flexibilized by suitable measures, so that it can be folded in this line against the base member. Subsequently, a flexible transverse line (dashed lines 18b) is generated at intervals of the package length, so that a multiplicity of information carrier surfaces are formed. If one wishes a distance 19 in the size of the packing thickness between the base member and the information carrier stack, as in FIG. 10b 1, the strip first flexibilizes at this distance from the line 18a at 18c across its length, and then, as described above, the flexible transverse lines 18b are created.

After mounting the base member on the package, the information carrier surfaces can be folded in a zigzag fold to form an information carrier stack, wherein the embodiment of the FIG. 9 receives, or it can be glued two consecutive information carrier sections with the facing surfaces, wherein the embodiment of the FIG. 8 is obtained.

In an alternative manufacturing method, a base member and information carrier are cut from one of the above-mentioned materials, and the base member and information carrier materials may be the same or different. From the blank for the base element Schlitzdurchlässe or open apertures are punched, which can be assigned by their shape and location depending on one or more trays of the blister pack to be labeled and their size allows the passage of the packaged objects. On the blanks for the information carrier larger areas for receiving the information (information surfaces), and if necessary smaller for the attachment of the individual elements to each other (mounting surfaces) provided and, where appropriate, for example, by applying adhesives to the mounting surfaces and / or the generation of the information suitable, printable and / or pasted surfaces in the information surfaces prepared for these functions. Between information and mounting surfaces of the information carrier flexible hinging kinks are inserted and then the information carrier and base elements are attached to the mounting surfaces by the above-mentioned known mechanical or adhesive fastening means to each other.

A variant of this manufacturing method is that the cover sheet or the thermoforming foil having thermoforming foil of the blister pack is used as a base element and prepared for this function.

In order to produce preferred embodiments, the production methods described can be modified and / or supplemented, as can be seen in an illustrative manner from the description of these embodiments and, where appropriate, the figures.

Free adhesive layers are expediently covered with release liners and protected. The information can be applied to the information surfaces in a production stage that best suits the operational circumstances. If desired, the labels can also be delivered without information to consumers who want to provide the information themselves. The order of these manufacturing measures can be adapted as much as possible to operational requirements.

Another object is the use of the multi-part label according to the invention for the identification of primary and secondary packaging, in particular blister packs.

The following exemplary embodiments illustrate the production of multi-part labels according to the invention. However, the object of the invention is not limited to the illustrated embodiments.

example 1

• Aus einem wärmegebondeten Polyesterfaser-Vliesstoff mit einem Flächengewicht von 100 g/m² wird ein rechteckiger Streifen in der Größe 72,6x5,5 cm ausgeschnitten. Auf seiner Oberseite wird der Streifen mit einem Titandioxid enthaltenden Papierstrich versehen. Nach dem Trocknen wird auf der Unterseite eine Kontaktkleberbeschichtung aufgetragen und nach den Abdunsten mit einer passenden PTFE-imprägnierten abziehfähigen Schutzfolie abgedeckt.

For a blister pack with a cover area of 6.5x5.5 cm and 10 trough-shaped wells with an upper opening of 0.75x1.75 cm and a depth of 1.0 cm, which are arranged evenly in two rows, so that between the two Rows of trays having a central web of 1 cm width and between the trays of a row and to the edges of the covering surface frame webs of 0.5 cm width, a suitable multi-part label according to the invention is produced as follows:

• From a heat-bonded polyester fiber nonwoven fabric having a basis weight of 100 g / m ² , a rectangular strip in the size 72.6x5.5 cm is cut out. On its upper side, the strip is provided with a titanium dioxide-containing paper coating. After drying, a contact adhesive coating is applied to the bottom and covered after evaporation with a suitable PTFE-impregnated peelable protective film.

From the lying at the beginning of the thus prepared strip surface of 6.5 x 5.5 cm 10 openings are punched out, according to the size and arrangement of the troughs of blister pack.

Subsequently, the protective film covering the contact adhesive is slit at a distance of 6.5 cm, 7.6 cm and then after a further 6.5 cm in each case. Beginning from the end of the strip of each of the 6.5 cm long sections are now deducted the protective films, and the sections are bent together so that the adhesive fields come to lie in register with each other, and then united by a short pressure. This procedure is continued until 10 of the surfaces have been combined into 5 double surfaces. There then remains a 1.1 cm long field of the strip and the punched-out initial field of the strip.

The stamped field serves as a base element for securing the label to the cover surface of the blister pack, the 1.1 cm length field serves to deposit the information carriers on the tub side of the pack.

Information can either be applied to the free sides of the information carriers after the described production of the label, e.g. by sticking labeled self-adhesive labels, or they can be printed at any time after the paper has dried.

The information bearing surface may also be wholly or partially stored on the receptacle of another kind, e.g. magnetic or opto-electronic data. The application of the paper coating is then replaced in whole or in part by the attachment of a corresponding other storage medium.

Analogously, smaller multi-part labels according to the invention, e.g. those in which the center bar between the tubs only about 0.5 cm and the frame bars are only about 0.3 cm wide produce

Example 2

Example 1 is repeated with the difference that the nonwoven strip is provided only in its initial section of 6.5 cm in length with an adhesive layer and covered with protective film. On the remaining length it is coated on both sides with the paper line. After punching the passages, the strip is folded into a zigzag stack.
