Child-resistant packaging for tablets

Abstract
A child-resistant yet senior-friendly packaging for tablets, capsules or similar pharmaceutical products. The packaging is a blister pack (12) with at least one cup (24) that receives tablets in an external package (10), arranged between a base part (14) and an intermediate part (16), and that is closed by a cover film (26) that can be pressed through. The intermediate part (16) is covered by a cover part (18). A first adhesive (30) is arranged between the base part (14) or the blister pack (12) and the intermediate part (16). A second adhesive (32) is arranged between the intermediate part (16) and the cover part (18). The second adhesive (32), in the closed state of the external package (10), has a lower adhesiveness vis-à-vis the first adhesive (30) and, once the cover part (18) is released from the intermediate part (16), a higher adhesiveness vis-à-vis the first adhesive (30).
Description




The invention concerns a child-safe packing for tablets, capsules and similar pharmaceutical products with a blister pack with at least one cup to hold the tablets or capsules sealed by a push-through cover film, where over the blister pack fitted with an outer pack is arranged an intermediate part and the intermediate part is covered by a cover part, where the cover from of the blister pack faces towards the intermediate part, where between the blister pack and the intermediate part is arranged a first adhesive and between tithe intermediate part and the cover part is arranged a second adhesive, and where when the outer pack is closed, the second adhesive has a power adhesive force than the first adhesive.




The invention also concerns a child-safe packing for tablets, capsules and similar pharmaceutical products, with a blister pack with at least one cup to hold the tablets sealed by a push-through cover film, where over the blister pack fitted with an outer pack is arranged an intermediate part, where the cover film of the blister pack faces towards the intermediate part, and where between the blister pack and the intermediate part is arranged a first adhesive.




The invention also concerns a child-safe packing for tablets, capsules and similar pharmaceutical products with a blister pack with at least one cup to hold the tablets sealed by means of a push-through cover film, where the blister pack in an outer pack is arranged between a base part and a cover part, where the cover part is covered by a sealing part, where the cover film of the blister pack faces towards the cover part, and where, with the outer pack closed, between the base part or the blister pack and the cover part is arranged a first adhesive.




The invention further concerns a child-safe packing for tablets, capsules and similar pharmaceutical products with a blister pack with at least one cup to hold the tablets closed by a push-through cover film, where over the blister pack fitted with an outer pack is arranged a first cover part and the first cover part is overlaid by a second cover part, and where the cover film of the blister pack faces towards the first cover part.




The invention also concerns a child-safe packing for tablets, capsules and similar pharmaceutical products with a blister pack with at least one cup to hold the tablets closed by a push-through cover film, where the blister pack is arranged in an outer pack between a base part and a first cover part, where the first cover part is overlaid by a second cover part, and where the cover film of the blister pack faces towards the first cover part.




The danger of unsupervised consumption of drugs is undisputed, where in particular small children are greatly exposed to this potential risk especially when drugs are left lying around.




Blister packs have become the predominant form of packaging for tablets and capsules. Push-through packs, in which the tablets are pushed through a cover film from a cup in the base of the packing, have become very common. In other known blister packs a cover film is removed by peeling. Other blister packs have a notch as a tear aid.




The possibilities exploited today for increasing the child-safety of the said blister packs for tablets and capsules consist of rendering opening more difficult by measures which require increased force, e.g. thicker push-through films, stronger adhesion of peel films or high tear resistance at tear notches.




Packs which can only be opened with increased use of force are indeed child-safe but can constitute a problem for the elderly.




A child-safe packing of the type described initially is known from U.S. Pat. No. 3,912,082.




The invention is therefore based on the task of creating a child-safe packing of the type described initially which can easily be opened by the elderly. Essentially, the packing is structured such that its opening requires a combination skill, or simultaneous movements must be performed, or procedures which require coordination or combination of individual steps.




A first solution to the task according to the invention is a child-safe packing for tablets, capsules and similar pharmaceutical products with a blister pack with at least one cup to hold the tablets sealed by a push-through cover film, where over the blister pack fitted with an outer pack is arranged an intermediate part and the intermediate part is covered by a cover part, where the cover film of the blister pack faces towards the intermediate part, where between the blister pack and the intermediate part is arranged a first adhesive and between the intermediate part and the cover part is arranged a second adhesive, and where when the outer pack is closed, the second adhesive has a lower adhesive force than the first adhesive, after separating the cover part from the intermediate part, the second adhesive has a higher adhesive force than the first adhesive.




A second solution to the task according to the invention is a child-safe packing for tablets, capsules and similar pharmaceutical products with a blister pack with at least one cup to hold the tablets sealed by a push-through cover film, where over the blister pack fitted with an outer pack is arranged an intermediate part, where the cover film of the blister pack faces towards the intermediate part, and where between the blister pack and the intermediate part is arranged a first adhesive, the intermediate part is partly covered by a removable separating part and a cover part lies on the separating part, in that between the intermediate part and the separating part is arranged a second adhesive, and between the intermediate part not covered by the separating part and the separating part and the cover part is arranged a third adhesive, where the third adhesive has a lower adhesive force than the first adhesive and the second adhesive has a higher adhesive force than the first adhesive.




To achieve greater stability of the packing, the blister pack can be arranged in an outer pack between a base part and the intermediate part and the first adhesive can be arranged between the base part or blister pack and the intermediate part.




A third solution to the task according to the invention is a child-safe packing for tablets, capsules and similar pharmaceutical products with a blister pack with at least one cup to hold the tablets sealed by means of a push-through cover film, where the blister pack in an outer pack is arranged between a base part and a cover part, where the cover part is covered by a sealing part, where the cover film of the blister pack faces towards the cover part, and where, with the outer pack closed, between the base part or the blister pack and the cover part is arranged a first adhesive, the sealing part is covered by a tear-off part, in that between the base part and the sealing part is arranged a second adhesive, where the second adhesive has a higher adhesive force than the first adhesive, and the sealing part, with the outer pack closed is folded about a first fold line (k) and on opening the outer pack, about a second fold line (l), and where after folding the sealing part about the second fold line (l), the second adhesive is arranged between the sealing part and the cover part.




A fourth solution to the task according to the invention is a child-safe packing for tablets, capsules and similar pharmaceutical products with a blister pack with at least one cup to hold the tablets closed by a push-through cover film, where over the blister pack fitted with an outer pack is arranged a first cover part and the first cover part is overlaid by a second cover part, and where the cover film of the blister pack faces towards the first cover part, the second cover part is overlaid by a sealing part lying on this, in that the sealing part has a removal opening opposite the cup of the blister pack and sealed by the second cover part when the outer pack is closed, and optionally covered by a push-through opening seal, in that the two cover parts are connected together at one end and at the other end each is connected to one end of the blister pack or the sealing part, and the blister pack is connected to the sealing part at their other ends to form grip tabs, in that the grip tabs of the two cover parts lie within a loop formed by the blister pack and sealing part, and in that with the outer pack closed, between the first cover part and the blister pack and between the second cover part and the sealing part there is a releasable connection which is separated after opening the outer pack after pulling on the grip tabs, where in this open position of the outer pack, the cover film over the cup of the blister pack lies opposite the removal opening.




A variant of the invention with greater stability is a child-safe packing for tablets, capsules and similar pharmaceutical products with a blister pack with at least one cup to hold the tablets closed by a push-through cover film, where the blister pack is arranged in an outer pack between a base part and a first cover part, where the first cover part is overlaid by a second cover part, and where the cover film of the blister pack faces towards the first cover part, the second cover part is overlaid by a sealing part lying on this, in that the first sealing part has a removal opening opposite the cup of the base part and sealed by the second cover part when the outer pack is closed, and optionally covered by a push-through opening seal, in that the two cover parts are connected together at one end and at the other end each is connected to one end of the base part or sealing part, and the base part is connected to the sealing part at their other ends to form grip tabs, in that the grip tabs of the two cover parts lie within a loop formed by the base part and the sealing part and in that with the outer pack closed, between the first cover part and the base part and between the second cover part and the sealing part there is a releasable connection which is separated after opening the outer pack after pulling on the grip tabs, where in this open position of the outer pack the cover film over the cup of the base part lies opposite the removal opening.




In a first preferred embodiment of: the fourth solution to the task according to the invention, the connection between the first cover part and the blister pack or the base part and between the second cover part and the sealing part is glued or sealed separably.




In a second preferred embodiment of the fourth solution to the task according to the invention, when the outer pack is closed an adhesive is arranged between the first cover part and the blister pack or the base part and between the second cover part and the sealing part, and after the outer pack has been opened after pulling on the grip tabs, between the two cover parts or between the base part and sealing part, where in this open position of the outer pack the cover film over the cup of the blister pack lies opposite the removal opening.




The principle common to all four solutions according to the invention lies in the use of adhesives of different adhesion force or separable glued or sealed laminates. The opening of the packs according to the invention requires a combination ability in the sense that before pressing through the tablets, various parts of the packing must be separated from each other and pressed back together.




In the packings with a base part, the cup of the blister pack preferably protrudes outwards from the plane formed by the base part, where in the simplest case the cup of the blister pack penetrates an opening in the base part. If the base part consists of a deformable material, a cup can also be formed from this and the cup of the blister pack arranged in the cup of the base part.




The outer packs can be produced particularly economically from a single cut-out.




At least two packings can be combined into multi-portion packs, where the individual packings are arranged next to each other in a strip pack and preferably can be separated from the strip pack along a weakening line, preferably a perforation line.




For production of the packing according to the invention, rigid, semi-rigid and flexible materials known today for the production of packaging, in the form of sheets, films, laminates or other layer materials in a thickness from a few mm to a few mm, preferably from 8 mm to 3 mm, can be used. Examples of film-like materials are metal foils such as aluminum foil. Other examples of film-like materials are paper, semi-cardboard and cardboard. Particularly important are plastic containing films, e.g., those based on polyolefins such as polyethylenes or polypropylenes, polyamides, polyvinyl chloride, polyesters such as polyalkylene terephthalates and, in particular, polyethylene terephthalate. The plastic-containing films can be monofilms of plastics, laminates of two or more plastic films, laminates of metal and plastic films. The individual layers of the film-like A materials can be attached to each other by means of adhesives, pastes, adhesive promotion agents and/or by extrusion coating, coextrusion or laminating, etc. Suitable plastic films are, for example, non-oriented or axially or biaxially oriented monofilms or laminates of two or more non-oriented or axially or biaxially oriented films of plastics based on polyolefins such as polyethylenes or polypropylenes, polyamides, polyvinyl chloride, polyesters such as polyalkylene terephthalates and, in particular, polyethylene terephthalate, cyclo-olefin-copolymers (CO) and polychlorotrifluoroethylene (PCTFE, trademark ACLAR).




Particularly suitable for the base parts of blister packs are transparent plastics with good molding properties such as polyethylene, polypropylene, cyclo-olefin-copolymers (COC), polyvinyl chloride, polyethylene terephthalate, polyainide and laminates made from said materials, e.g., PVC and polychlorotrifluoroethylene (PCTFE) or PVC and PVDC (polyvinyldichloride). For non-transparent blister packs, for example, laminates are used of an aluminum film coated on both sides with a plastic film with, for example, the structure polyamidelaluminum/PVC or pigmerited plastic films. The cover film is usually an aluminum of a thickness of, e.g., 20 μm which can be painted and/or coated with a hot seal lacquer.




All of the above film-like materials such as paper, semi-cardboard, cardboard and plastic films in the form of monofilms, laminates, etc., can have at least one further continuous layer of ceramic materials, sputtered or deposited from a vacuum in a thickness of approximately 5 to 500 nm (nanometers), for example, Al


2


O


3


or SiO


x


, where x is a figure between 1.5 and 2. These layers of ceramic materials have barrier properties and prevent the diffusion of gases and water vapors through the packing.

A first embodiment of an outer pack


10


for a blister pack


12


shown in

FIGS. 1

to


5


of essentially strip-like shape has a base part


14


of, for example, cardboard, a film-like intermediate part


16


and an also film-like cover part


18


—both films made, for example, made from polyethylene terephthalate (PET). The blister pack


12


—in the example shown, a single-portion pack for a tablet


20


—has a base part


22


of, for example, polyvinyl chloride (PVC) with a cup


24


molded from this to hold a tablet


20


, and a cover film


26


of, for example, aluminum sealed or glued to the base part


22


. The cup


24


of the blister pack


12


penetrates a base opening


28


adapted to the periphery of the cup


24


in the base part


14


of the outer pack


10


and protrudes outward from the base part


14


. The base part


22


of the blister pack


12


lies on the inside of the base part


14


of the outer pack


10


and is at least partly glued to this by way of a permanent adhesive based, for example, on polyurethane. Instead of the base opening


28


, where the material allows, a cup can also be formed from the base part


14


, i.e., the cup


24


of the blister pack


12


would in this case be held by the cup in the base part


14


.




The intermediate part


16


is glued to the base part


14


or the blister pack


12


by way of a first adhesive


30


. The cover part


18


lying on the intermediate part


16


is glued by way of a second adhesive


32


to the intermediate part


16


and projects over the base part


16


to form an adhesive-free tear tab


34


. At the end of the outer pack


10


remote from the tear tab


34


, the base part


14


, blister pack


12


, intermediate part


16


and cover part


18


are permanently glued to each other.




In the closed outer pack


10


, the second adhesive


32


between the cover part


18


and intermediate part


16


has a lower adhesion force than the first adhesive


30


between the intermediate part


16


and base part


14


or blister pack


12


. The first adhesive


30


is for example an adhesive based on polyacrylate, other adhesive resins or an adhesive with a micro-encapsulation system. The second adhesive


32


is a reactive adhesive, the adhesion force of which for example rises in an oxygen atmosphere. The increase in adhesion force can be also caused however by other factors such as pressure, relative humidity etc.




To remove the tablet


20


first the cover part


18


is held at its tear tab


34


and through an opening movement performed in arrow direction A separated from the intermediate part


16


below. In this position the second adhesive


32


is freely exposed to the ambient atmosphere, whereby its adhesion force increases due to a reaction with oxygen such that it exceeds the adhesion force of the first adhesive


30


. In a next step the cover part


18


with the reacted second adhesive


32


is re-placed on the intermediate part


16


in arrow direction B and connected with the intermediate part by way of the reacted second adhesive


32


. In a variant with micro-encapsulation system, the tear tab


34


must be pressed firmly onto the intermediate part for example by pushing or rubbing between fingers. In a subsequent step the tear tab


34


of the cover part


18


is held again and pulled away from the base in an opening movement performed in arrow direction C. As the adhesion force of the second reacted adhesive


32


is now greater than the adhesion force of the first adhesive


30


, in the opening movement in arrow direction C a separation occurs between the intermediate part


16


and the base part


14


or blister pack


12


. In this process the cover film


26


of the blister pack


12


is exposed. In this open position the tablet


20


can be pushed through the cover film


26


by finger pressure on the cup


24


in arrow direction D and ejected. In a variant the cover film


26


is separated from the blister pack


12


in the opening movement in arrow direction C so that the tablet


20


can be removed without pushing through the cover film


26


.




The base part


14


which serves for stability of the outer pack


10


can be omitted in another embodiment not shown in the drawing. Here, the cover part


18


can be connected as one piece with the blister pack


12


or its base part


22


and form a loop i.e. the outer pack consists of one and the same material e.g. the blister pack or its base part.





FIG. 6

shows a strip-like pack


40


with six individual packings according to

FIG. 1

arranged next to each other. These can be separated from each other by linear perforations


42


. The individual outer packs


10


can however also be opened without needing to be separated from the packing strip


40


.




A second embodiment shown in

FIGS. 7

to


11


of an outer pack


50


for a blister pack


52


of essentially strip-like structure is fitted with base part


54


, an intermediate part


56


, a separate part


57


and a cover part


58


. The blister pack


52


—in the example shown, a single-portion pack for a tablet


60


—has a base part


62


of, for example, polyvinyl chloride (PVC) with a cup


64


formed from this to hold the tablet


60


and a cover film


66


of, for example, aluminum sealed or glued to the base part


62


. The cup


64


of the blister pack


52


penetrates a base opening


68


adapted to the periphery of the cup in the base part


54


of the outer pack


50


and protrudes outward from the base part


54


. The base part


62


of the blister pack


60


lies on the inside of the base part


54


of the outer pack


50


and is at lest partly glued to this by way of a permanent adhesive based, for example, on polyurethane. Instead of the base opening


68


, where the material allows, a cup can also be formed from the base part


54


, i.e., the cup


64


of the blister pack


52


would in this base be held by the cup in base part


54


.




The intermediate part


56


is glued to the base part


54


or the blister pack


52


by way of a first adhesive


70


. The separating part


57


lying on the intermediate part


56


covers a zone


76


separated from an edge area


72


and with a second adhesive


74


. The cover part


58


lying on the intermediate part


56


and separating part


57


is glued by way of a third adhesive


78


to the edge area


72


of the intermediate part


56


and projects over the intermediate part


56


to form an adhesive-free tear tab


80


. At the end of the outer pack


50


remote from the tear tab


80


, the base part


54


, intermediate part


56


and cover part


58


are permanently glued together. The separating part


57


covering the second adhesive


74


projects over the intermediate part


56


to form an adhesive-free grip tab


82


.




In the closed outer pack


50


the third adhesive between the cover part


58


and the intermediate part


56


has a lower adhesion force than the first adhesive


70


between the intermediate part


56


and the base part


54


or blister pack


52


. The second adhesive


74


of the zone of the intermediate part


56


covered by a separating part


57


has a greater adhesion force than the first adhesive


70


, where the material for the separating part


57


is selected so that compared with the second adhesive


74


only a very low adhesion force is generated, and compared with the third adhesive


78


practically no adhesion force. The adhesives


70


,


74


,


78


are for example adhesives based on polyacrylate or other adhesive resins.




To remove the tablet


60


first the cover part


58


is held at its tear tab


80


and by an opening movement performed in arrow direction E separated from the intermediate part


56


below and the separating part


57


lying on this. In the next step the separating part


57


is held at its grip tab


84


and pulled in arrow direction F away from the intermediate part


56


to expose zone


76


with the second adhesive


74


of the intermediate part


56


. In a variant with micro-encapsulation system, the tear lab


80


must be pressed on firmly. In a subsequent step the cover part


58


is replaced in arrow direction G on the intermediate part


56


with the now exposed zone


76


with the second adhesive,


74


, and connected to the intermediate part


56


by way of the exposed second adhesive


74


. In a subsequent step the tear tab


80


of the cover part


58


is held again and pulled away from the base in an opening movement performed in arrow direction H. As the adhesion force of the second adhesive


74


is greater than the adhesion force of the first adhesive


70


, in the opening movement in arrow direction H a separation occurs between the intermediate part


56


and the base part


54


or blister pack


52


. In this process the cover film


66


of the blister pack


52


is exposed. In this open position the tablets


60


can be pushed by finger pressure on cup


64


in arrow direction I through the cover film


66


and ejected. In a variant the cover film


66


is already separated from the blister pack


52


in the opening movement in arrow direction I so that the tablet


60


can be removed without pushing through the cover film


66


.




The base part


54


which serves for stability of the outer pack


50


can be omitted in another embodiment not shown in, the drawing. Here, the cover part


58


can be connected as one piece with the blister pack


52


or its base part


62


and form a loop i.e. the outer pack consists of one and the same material e.g. the blister pack or its base part.





FIG. 12

shows a pack


90


with four square individual packings according to FIG.


7


. These can be separated from each other by linear perforations


92


. The individual outer packs


10


can however also be opened without needing to be separated from the pack of four


90


. The tear tab


80


of the cover part


58


and grip tab


82


of the separating part


57


are here facing towards the centre of the pack


90


whereby the pack is easy to produce.




A third embodiment shown in

FIGS. 13

to


17


of an outer pack


100


for blister pack


102


of essentially strip-like shape is fitted with a base part


104


, a cover part


106


, a sealing part


108


and a tear-off part


120


. The blister pack


102


—in the example shown, a single-portion pack for a tablet


110


—has a base part


112


of, for example, polyvinyl chloride (PVC) with a cup


114


molded from this to hold the tablets


110


, and a cover film


116


, for example, of aluminum sealed or glued to the base part


112


. The cup


114


of the blister pack


102


penetrates a base opening


118


adapted to the periphery of the cup


114


in the base part


104


of the outer pack


100


and protrudes outwards from the base part


104


. The base part


112


of the blister pack


102


lies on the inside of the base part


104


of the outer pack


100


and is at least partly glued to this. Instead of the base opening


118


, where the material allows, a cup can also be formed from the base part


104


, i.e., the cup


114


of the blister pack


102


would in this case be held by the cup in the base part


104


.




The base part


104


, sealing part


108


and tear-off part


120


are connected together as one piece as strips of for example cardboard and when the outer pack


100


is closed are laid over each other in three layers to form a double loop, where the fold is such that the free ends of the base part


104


and tear-off part


120


project at the sides in the strip longitudinal direction as grip tabs


122


,


124


. The film-like cover part


106


of for example polyethylene terephthalate (PET) extends, covering the blister pack


102


, over part of the base part


104


and is glued by way of a first adhesive


126


with the base part


104


or blister pack


102


and the cover part


106


. With the outer pack


100


closed, the sealing part


108


is folded about a first fold line k and by way of a second adhesive


128


glued to the base part


104


below. This second adhesive


128


is arranged in the form a transverse strip on the sealing part


108


at the transition to the tear-off part


120


. The tear-off part


120


lying on the sealing part


108


is glued to this by way of an adhesive point


130


lying in the area of the transition to the base part


104


. The adhesive point


130


can for example take the form of a seal. The second adhesive


128


has a higher adhesion force than the first adhesive


126


between the cover part


106


and base part


104


.




To remove the tablet


110


, first the grip tabs


122


and


124


are held and pulled apart on both sides in arrow direction K. In this process the tear-off part


120


becomes detached at adhesive point


130


from the sealing part


108


and the sealing part


108


detached from the base part


104


at the strip of the second adhesive


128


. The outer pack


100


extended into a strip of maximum length is now folded back in arrow direction L about a second fold line I. The position of fold line I is arranged so that after folding, the strip-like second adhesive


128


applied to the closing strip now lies on the cover part


106


and is glued to this after a slight pressure between two fingers.




In a further opening step the tear-off part


120


is held and pulled away from the base in an opening movement performed in arrow direction M. As the adhesion force of the second adhesive


128


is greater than the force of the first adhesive


126


, the opening movement in arrow direction M leads to a separation between the cover part


106


and the base part


104


or blister pack


102


. In this process the cover film


116


of the blister pack


102


is exposed. In this open position the tablet


110


can be pushed through the cover film


116


by finger pressure on cup


114


in arrow direction N and ejected.




A fourth embodiment shown in

FIGS. 18

to


22


of an outer pack


140


of, for example, cardboard for a blister pack of


142


essentially strip-like shape has a base part


144


and a sealing part


146


. The blister pack


142


—in the example shown, a single portion pack for a tablet


148


—has a base part


150


of, for example, polyvinyl chloride (PVC) with a cup


152


formed from this to hold the tablet


148


, and a cover film


154


of, for example, aluminum sealed or glued to the base part


150


. The cup


152


of the blister pack


142


penetrates a base opening


156


adapted to the periphery of the cup


152


in the base part


144


of the outer pack


140


and protrudes outwards from the base part


144


. The base part


150


of the blister pack


142


lies on the inside of the base part


144


of the outer pack


140


and is at least partly glued to this. Instead of the base opening


156


, where the material allows, a cup can also be formed from the base part


144


, i.e., the cup


152


of the blister pack


142


would in this case be held by the cup in the base part


144


.




The sealing part


146


is brought together with the base part


144


in a first grip tab


158


and fixed here. Two film-like cover parts


160


,


162


are connected by way of an adhesive


164


with the base part


144


or blister pack


142


and sealing part


146


and brought together and fixed in a second grip tab


166


opposite the first grip tab


158


. At their ends remote from the first and second grip tabs


158


,


166


, the cover parts


160


,


162


and the base part


144


or sealing part


146


connected to these by way of the adhesive


164


are brought together and fixed in a third and fourth grip tab


168


,


170


.




The base part


144


of the outer pack


140


with the sealing part


146


forms a loop where the base part


144


and sealing part


146


are approximately parallel to each other. The sealing part


146


has a removal opening


172


opposite the base opening


156


or cup


152


. This removal opening is closed by the cover part


162


. The sealing part


146


is fixed to the base part


144


in the area of the third and fourth grip tabs


168


,


170


, opposite each other in the closed outer pack


140


, by way of an adhesive point


174


to enclose the second grip tab


166


. The adhesive point


174


can for example also take the form of a seal.




To remove the tablet


148


the third and fourth grip tabs


168


,


170


are held and pulled apart in arrow direction O, exposing the second grip tab


166


. In a second step the first and second grip tabs


156


,


166


are held and pulled apart in arrow direction P. In this process the cover parts


160


,


162


are detached from the base part


144


and sealing part


146


so that on complete extension in arrow direction P the base part


144


lies opposite the sealing part


146


and is glued to this by way of the adhesive


164


. In the same way at the end of the stretch process the two cover lo parts


160


,


162


lie on each other and are glued together by way of the adhesive


164


. In this process the removal opening


172


is opened and now—separated only by the cover film


154


—exposes the tablet


148


in cup


152


opposite. In this open position the tablet


148


can be pushed by finger pressure on cup


152


in arrow direction Q through the cover film


154


and ejected through the removal opening


172


. The removal opening


172


can also be covered by a push-through opening seal. This additional seal is for example limited by a weakening line, e.g. a perforation line, and is separated at the same time as the cover film


154


is pushed through.




In a variant of the latter embodiment of an outer pack


140


the base part


144


is omitted i.e. the blister pack


142


or its base part


150


extends between the grip tabs


158


,


168


.




Instead of the adhesive


164


, the base part


144


or blister pack


142


can be releasably connected with the first cover part


160


and second cover part


162


with the sealing part


146


, where this connection is for example glued or sealed. In the case of a seal, a laminate is formed which is separable at the sealing layer or seam.
