Description

[0040] FIG. 1 shows an example of an individual blister 1 in plan view and from two sides. The individual blister 1 comprises a planar main body 2, in which a bubble 3 is formed. In the bubble 3 there is situated a single medicinal product portion (not illustrated in FIG. 1). The bubble is closed by a cover film 4. The bubble 3 is formed centrally in the planar main body 2. The basic shape of the main body is rectangularthe corners being rounded.

[0041] The cover film extends usually, but not necessarily, over the entire rear side of the main body and terminates flush with the edges of the main body. The cover film thus preferably likewise has the basic shape of the main body and in the ideal case is flat (without curvature).

[0042] In the stack according to the invention, the cover films preferably lie in planes extending parallel to one another.

[0043] There are various possibilities for stacking which, in the case of cover films extending in parallel, are provided by the orientation of the cover films with respect to the direction of the force of gravity. In the simplest case the cover films extend horizontally to the force of gravity and the individual blister packs are stacked on top of one another. In another case the cover films extend vertically to the force of gravity and the individual blister packs are stacked adjacently. In addition, the cover films can be brought into any other orientation between vertical and horizontal by rotation of the stack. The present invention is not limited to any orientation of the stack with respect to the force of gravity. The term stack in the present description is interpreted more broadly than in colloquial language, in which case it is usually understood to mean only an arrangement on top of one another. The term height h.sub.S of the stack-like arrangement also is not to be understood to mean that only individual blisters stacked on top of one another are the subject of the present invention. The term height is thus interpreted here more broadly than is usually understood thereby. These considerations, which are assumed of cover films extending in parallel, also are not intended such that they apply only to stacks with cover films extending in parallel. By way of example, the present invention also includes stacks in which the cover films of the individual blisters do not lie in planes extending parallel to one another.

[0044] For the following consideration, a stack is assumed in which the cover films of the individual blisters are arranged horizontally to the force of gravity, and the individual blisters are therefore arranged on top of one another. This therefore results in an individual blister disposed at the very bottom in the stack and an individual blister disposed at the very top in the stack. Further individual blisters can be situated therebetween. In a stack of this type an adjacent individual blister is to be understood to mean the individual blister that is in contact with the individual blister in question. Here, the adjacent individual blister can be situated above or below the individual blister in question. The individual blister at the very bottom has only a single adjacent individual blister; this lies above the individual blister situated at the very bottom. Similarly, the individual blister at the very top also has just one adjacent individual blister; this lies below the individual blister situated at the very top. Should further individual blisters be provided between the individual blisters at the very bottom and at the very top, these each have two adjacent individual blisters, one of the adjacent individual blisters being situated above the individual blister in question, and the other of the adjacent individual blisters being situated below the individual blister in question. Similar considerations apply to a stack in which the individual blisters are arranged adjacently.

[0045] Typical numbers N of individual blisters in a stack-like arrangement are 2, 3, 4, 5, 6, 7, 8, 9, 10, 12, 14, 16, 18, 20, 21, 28, 30 and 31. However, other quantities are also conceivable.

[0046] In a preferred embodiment, N is an integer in the range from 2 to 31.

[0047] In a further preferred embodiment, N is 7.

[0048] In a further preferred embodiment, N is 28.

[0049] In the stack according to the invention the bubbles preferably point in the same direction. However, it is also conceivable for the individual blisters to be arranged rear side to rear side and belly side to belly side in alternation. Mixed forms of the specified stack forms are also conceivable.

[0050] In a conventional blister stack, in which N blisters are stacked rear side to belly side, the height h.sub.S of the stack-like arrangement is N times the sum of the height h.sub.B of a bubble, the thickness d.sub.G of a flat main body and the thickness d.sub.D of a cover film:

Conventional blister stack: h.sub.S=N.Math.(h.sub.B+d.sub.G+d.sub.D)

[0051] This is illustrated in FIG. 2, where, for schematic reasons, the thickness D of the film composite consisting of the flat main body and the cover film is specified. The following is true: D=d.sub.G+d.sub.B.

[0052] The stack height is reduced in accordance with the invention:

blister stack according to the invention: h.sub.S<N.Math.(h.sub.B+d.sub.G+d.sub.B)

[0053] In a preferred embodiment the height of the stack-like arrangement is:

h.sub.S=N.Math.(d.sub.G+d.sub.D)+h.sub.B

[0054] In a particularly preferred embodiment, the following is true for the stack height:

N.Math.(d.sub.G+d.sub.D)+h.sub.Bh.sub.S<N.Math.(h.sub.B+d.sub.G+d.sub.D)

in a further preferred embodiment the height of the stack-like arrangement is:

h.sub.S=(N1).Math.(d.sub.G+d.sub.D+h.sub.N)+(h.sub.B+d.sub.G+d.sub.D), where h.sub.N<h.sub.B

h.sub.N denotes the height of the supporting structures, which will be described in greater detail further below.

[0055] In a further preferred embodiment the height of the stack-like arrangement is:

h.sub.S=.Math.(N+1).Math.(h.sub.B+d.sub.G+d.sub.D)

[0056] In one embodiment of the present invention the individual blisters are stacked such that the cover film of an individual blister rests on the main body of an adjacent individual blister in a region that lies beside the bubble. FIG. 3 illustrates this embodiment.

[0057] FIG. 3 shows an example of an arrangement according to the invention in plan view (bottom) and from a side (top). Seven examples (1-1, 1-2, 1-3, 1-4, 1-5, 1-6, 1-7) of the individual blister 1 from FIG. 1 are arranged on top of one another in a stack-like manner. All bubbles point in the same direction. The individual blister 1-1 is arranged at the very bottom in the stack. The individual blister 1-2 rests on the individual blister 1-1. Here, the cover film of the individual bubble 1-2 rests on the main body of the adjacent individual bubble 1-1, more specifically in a region beside the bubble. For the individual blister 1-7, it is specified which side is the belly side B and which side is the rear side R. The belly side B is therefore the side on which the bubble 3 protrudes from the main body 2. The rear side R is the side on which the cover film 4 is applied that closes the bubble 3.

[0058] The height of the stack-like arrangement shown in FIG. 3 is:

h.sub.S=N.Math.(d.sub.G+d.sub.D)+h.sub.B=7.Math.(d.sub.G+d.sub.D)+h.sub.B

[0059] If the stack from FIG. 3 is projected onto the plane extending parallel to the basic shapes (rectangle with rounded corners) of the flat main body (xy plane), the following area requirement F.sub.S results:

F.sub.S=7.Math.F.sub.E6.Math.F.sub.O

[0060] F.sub.E is, here, the area content of a single individual blister in the projection onto the plane disposed parallel to the basic shape of the planar main body (xy plane), and F.sub.O is the overlap region of two adjacent individual blisters in the same projection plane.

[0061] If N individual blisters are disposed adjacently in alignment on a table, their area requirement is N times the area requirement F.sub.E of an individual blister:

F.sub.S=N.Math.F.sub.E

[0062] The following is generally true for a stack-like arrangement according to the invention:

F.sub.S<N.Math.F.sub.E

[0063] The area requirement of a stack-like arrangement according to the invention is smaller than the area requirement of adjacently arranged individual blisters, since the individual blisters of the stack-like arrangement overlap in the xy projection plane.

[0064] For example, the following is true for a stack as shown in FIG. 3:

F.sub.S=N.Math.F.sub.E(N1).Math.F.sub.O

[0065] Preferred embodiments of stacks according to the invention or those that have a greater relative overlap region F.sub.O.sup.rel:

F.sub.O.sup.rel=F.sub.O/F.sub.E1

[0066] Preferably, F.sub.O.sup.rel is from 0.3 to 1, particularly preferably from 0.5 to 1.

[0067] The size of the relative overlap region can be maximized in different ways, for example by a decentralized arrangement of the bubbles and/or by recesses in the main body, as will be explained in greater detail hereinafter.

[0068] In a further embodiment of the present invention the bubbles of the individual blisters are arranged in a decentralized manner with respect to the basic shape of the planar main body.

[0069] The centre of the basic shape of the planar main body is determined either by its centre of symmetry or, if the basic shape has no centre of symmetry, by the centre of gravity of the basic shape. The bubble also has a centre, which is determined either by the centre of symmetry or, if the bubble has no centre of symmetry, by the centre of gravity of the bubble.

[0070] A decentralized arrangement of the bubble is to be understood to mean an arrangement in which the centre of the bubble does not coincide with the centre of the basic shape of the planar main body.

[0071] Due to the decentralized arrangement, there is a greater bubble-free area on the main body beside the bubble, on which area an adjacent individual blister can rest via its cover film. The adjacent individual blisters can thus move closer to one another in the xy plane, such that not only a denser packing of the individual blisters in the stack direction, but also perpendicularly thereto, results. FIGS. 4 and 5 illustrate this embodiment.

[0072] FIG. 4 shows an example of an individual blister 1 in plan view and from two sides. The individual blister 1 comprises a planar main body 2, in which a bubble 3 is formed. In the bubble 3 there is situated an individual medicinal product portion (not illustrated in FIG. 4). The bubble is closed by a cover film 4. The bubble 3 is formed in the planar main body 2 in a decentralized manner. The basic shape of the main body is rectangularthe corners being rounded.

[0073] FIG. 5 shows an example of an arrangement according to the invention in a plan view (bottom) and from a side (top). Seven examples (1-1, 1-2, 1-3, 1-4, 1-5, 1-6, 1-7) of the individual blister 1 from FIG. 4 are arranged on top of one another in a stack-like manner. All bubbles point in the same direction.

[0074] The height of this stack-like arrangement is:

h.sub.S=N.Math.(d.sub.G+d.sub.p)+h.sub.B=7.Math.(d.sub.G+d.sub.D)+h.sub.B

[0075] In a further embodiment the base area of each individual blister has a recess, within which the bubble of an adjacent individual blister can be placed. This also results in a denser packing both in the stack direction and perpendicularly thereto. FIGS. 6 and 7 illustrate this embodiment.

[0076] The height of this stack-like arrangement is:

h.sub.S=N.Math.(d.sub.G+d.sub.D)+h.sub.B

[0077] The term recess is to have a broad meaning here. Under consideration of the main body of conventional blister packs (for example see FIG. 1a of the laid-open application GB2184086A), the edges of the basic shape have a convex contour. By way of example, a circular, a square, and a rectangular basic shape always have a convex contour (see FIG. 6, for example). If, by contrast, a semi-circular recess is punched out in the edge region of a square basic shape, the contour of the basic shape is no longer convex at all points, but is concave in the region of the recess.

[0078] Accordingly, the expression basic areas with recess is to be understood to mean all basic areas where the contour, besides convex regions, also comprises at least one concave region.

[0079] The recess is preferably round, semi-circular, ellipsoidal, semi-ellipsoidal, or rectangular.

[0080] In a preferred embodiment two different individual blisters, which behave like an image and mirror image relative to one another, are stacked in alternation. FIG. 6 shows an example. The two individual blisters 1 and 1 behave like an image and mirror image relative to one another. Both have a planar main body 2, in which a bubble 3 for receiving a medicinal product portion is formed. The bubble is arranged in a decentralized manner with respect to the main body. Both main bodies have a semi-circular recess 5. FIG. 7 shows how two of the individual blisters 1 and 1 are arranged on top of one another in alternation in a stack-like manner. The stack height is:

h.sub.S=4.Math.(d.sub.G+d.sub.D)+h.sub.B

[0081] In a further embodiment the main body of each individual blister has supporting structures. The supporting structures can be formed in the main body, similarly to the bubble. It is also conceivable for the supporting structures to be applied to the main body. In accordance with the invention, the supporting structures have a lower height than the bubble: h.sub.N<h.sub.B.

[0082] In a stack of individual blisters with supporting structures, the cover film of an individual blister rests against the supporting structures of the adjacent individual blister. Such supporting structures lead to a stabilization of the stack, but possibly at the cost of the packing density in the stack direction.

[0083] The height of the stack-like arrangement is:

h.sub.S=(N1).Math.(d.sub.G+d.sub.B+h.sub.N)+(h.sub.B+d.sub.G+d.sub.D)=N.Math.(d.sub.G+d.sub.D)+(N1).Math.h.sub.N+h.sub.B

[0084] FIG. 8 shows an example. A bubble 3 is arranged in a decentralized manner in the main body 2 of the individual blister 1. A circular recess 5 is formed in the main body 2, in which recess a bubble of a further individual blister in a stack-like arrangement can be placed. The main body also has supporting structures in the form of two supporting nubs 7, of which the height h.sub.N is less than the height of the bubble h.sub.B.

[0085] In FIG. 9, two of the individual blisters from FIG. 8 are stacked on top of one another. Here, the lower individual blister is rotated through 180 relative to the upper individual blister, such that the bubble of the lower individual blister falls precisely into the recess in the upper individual blister. The main body of the upper individual blister rests on the supporting nubs of the lower individual blister. The height of the stack-like arrangement is:

h.sub.S=(N1).Math.(d.sub.G+d.sub.B+h.sub.N)+(h.sub.B+d.sub.G+d.sub.B)=2.Math.(d.sub.G+d.sub.D)+h.sub.B+h.sub.N

[0086] The size of the relative overlap region is F.sub.O.sup.rel=1

[0087] A special form of a base area with recess is the angular base area, which constitutes a particularly preferred embodiment. Here, the recess is rectangular. An example of an angular base area is shown in FIG. 10. An angular base area is understood to mean an area in which two area elements extend in different directions starting from a common area and delimit a free region between the area elements. In the preferred embodiment discussed here of a stack-like arrangement according to the invention, the bubble of an individual blister falls into the free region between the area elements of the main body of an adjacent individual blister. The area elements extending in different directions enclose an angle of less than 180. The angle preferably lies in a range from 120 to 60, particularly preferably in a range from 100 to 80; and the angle is most preferably 90. The area elements extending in different directions are preferably of the same shape; they are preferably rectangular. They can be the same size or different sizes. In a preferred embodiment they are the same size; in another preferred embodiment they are different sizes.

[0088] In FIG. 10 an individual blister having an angular main body is illustrated. The main body 2 comprises two rectangular area elements 6 and 6, which are arranged at an angle of 90 to one another and delimit a free region, in which the bubble of a further individual blister in a stack-like arrangement can be placed. The main body 2 has supporting structures in the form of supporting nubs 7, of which the height h.sub.N is less than the height h.sub.B of the bubble 3. FIG. 11 shows, in a plan view (bottom) and in a side view (top), how two of the individual blisters from FIG. 10 are stacked on top of one another.

[0089] The stack height is:

h.sub.S=(N1).Math.(d.sub.G+d.sub.D+h.sub.N)+(h.sub.B+d.sub.G+d.sub.D)=2.Math.(d.sub.G+d.sub.D)+(h.sub.N+h.sub.B)

[0090] The size of the relative overlap region is F.sub.O.sup.rel=2/3.

[0091] In a further embodiment, the bubble of each individual blister of a stack according to the invention is arranged in a decentralized manner with respect to the basic shape of the main body, and the main body additionally has a recess, in which the bubble of an adjacent individual blister can be placed. FIGS. 12 and 13 illustrate this embodiment. In FIG. 12, an individual blister 1 is illustrated, of which the main body 2 has two rectangular area elements 6 and 6, which are arranged at an angle of 90 to one another and delimit a free region, in which the bubble of a further individual blister can be placed in a stack-like arrangement. The main body 2 also has supporting structures in the form of a supporting rib 8. Twice the height h.sub.N of the supporting rib added to the thickness d.sub.G of the main body and the thickness d.sub.D of the cover film corresponds in the present example to exactly the height h.sub.B of the bubble: 2.Math.h.sub.N+d.sub.G+d.sub.D=h.sub.B

[0092] FIG. 13 shows how three of the individual blisters from FIG. 12 are stacked on top of one another in a spiraled manner.

[0093] The stack height is:

h.sub.S=(N1).Math.(d.sub.G+d.sub.D+h.sub.N)+(h.sub.B+d.sub.G+d.sub.D)=.Math.(N+1).Math.(h.sub.B+d.sub.G+d.sub.D)=2.Math.(h.sub.B+d.sub.G+d.sub.D)

[0094] The size of the relative overlap region is F.sub.O.sup.rel=1

[0095] FIGS. 14, 15, 16 and 17 show further embodiments of the present invention, in which the medicinal product portion and accordingly also the bubble have an elongate form.

[0096] In FIG. 14 an individual blister 1 is illustrated, of which the main body 2 has two rectangular area elements 6 and 6, which are arranged at an angle of 90 to one another and delimit a free region, in which the bubble of a further individual blister in a stack-like arrangement can be placed. The area elements 6 and 6 are of different sizes.

[0097] In FIG. 15 three of the individual blisters from FIG. 15 are stacked on top of one another.

[0098] FIG. 16 shows an individual blister 1, in the main body 2 of which a bubble 3 is arranged in a decentralized manner. A recess 5 is introduced into the main body 2, into which recess a bubble of a further individual blister in a stack-like arrangement can be placed. The main body also has supporting structures in the form of four supporting nubs 7, of which the height h.sub.N is less than the height of the bubble h.sub.B.

[0099] In FIG. 17 two of the individual blisters from FIG. 16 are stacked on top of one another. Here, the lower individual blister is rotated through 180 relative to the upper individual blister, such that the bubble of the lower individual blister falls precisely into the recess in the upper individual blister. The main body of the upper individual blister rests on the supporting nubs of the lower individual blister.

[0100] A further subject of the present invention is a box containing a stack-like arrangement according to the invention of individual blisters. The box serves as secondary packaging. It usually also contains a package leaflet containing information regarding taking the medicinal product portions. The box serves to stabilize the stack-like arrangement according to the invention. It consists for example of card, plastic, metal or also a composite material. In a preferred embodiment the box is a folding box made of card, as is also used for conventional blister strips.

[0101] In a preferred embodiment the box contains a viewing window, via which the remaining amount of individual blisters provided in the box can be determined.

[0102] In a further preferred embodiment the box has a lateral opening in the lower region of the box, via which a single individual blister can be removed from the box. On account of the force of gravity, the individual blisters remaining in the box move down when the lower individual blister is removed and can be individually removed in succession until the box is empty.

[0103] In FIG. 18 three boxes according to the invention are illustrated. The right-hand box contains seven individual blisters, the middle box contains fourteen individual blisters, and the left-hand box contains 28 individual blisters. The left-hand box has a viewing window on its side, via which viewing window the remaining number of individual blisters can be determined. The left-hand box also has an opening in the lower region, via which the individual blisters can be removed laterally.

[0104] A further subject of the present invention is constituted by individual blisters embodied in a particular manner in order to enable a stacking according to the invention.

[0105] In a preferred embodiment the individual blisters are characterized in that the bubble is arranged in a decentralized manner with respect to the main body. Particularly preferred embodiments are illustrated in FIGS. 4, 6, 8, 12, 14 and 16.

[0106] In a further preferred embodiment the individual blisters have a recess, in which the bubble of an adjacent individual blister in a stack-like arrangement according to the invention can be placed. Particularly preferred embodiments are illustrated in FIGS. 6, 8, 10, 12, 14 and 16.

[0107] In a further preferred embodiment the individual blisters have supporting structures, of which the height h.sub.N is less than the height of the bubble h.sub.B. In a further preferred embodiment, the height h.sub.B of the bubble corresponds to the sum of twice the height h.sub.N of the supporting structures, the thickness d.sub.G of the main body and the thickness d.sub.D of the cover film: h.sub.B=2.Math.h.sub.N+d.sub.G+d.sub.D. Particularly preferred embodiments are illustrated in FIGS. 8, 10, 12, 14 and 16.

[0108] In a further preferred embodiment, the main body of the individual blister according to the invention has a rectangular or square basic shape, in which the corners are optionally rounded. Particularly preferred embodiments are illustrated in FIGS. 4, 6, 8 and 16.

[0109] In a further preferred embodiment the main body of the individual blister according to the invention has an angular basic shape, in which the corners are optionally rounded. Particularly preferred embodiments are illustrated in FIGS. 10, 12 and 14.

[0110] In a further preferred embodiment the individual blister exists in two different copies, which behave like an image and mirror image relative to one another. A particularly preferred embodiment is illustrated in FIG. 6.

[0111] In a further preferred embodiment, the planar main bodies have one or more basic shapes which, apart from optionally rounded corners, allows/allow a tesselation of a rectangular area.

[0112] Tesselation (also referred to as tiling, paving or scrap-free blanking) is understood to mean the covering of an area by smaller areas of identical shape, with no gaps and no overlaps. The basic shapes of the planar main bodies form the sub-areas here. The advantage of tesselation lies in the fact that the main body can be obtained by dividing a larger blister sheet, wherein division leftovers (cutting leftovers, waste) are reduced to a minimum.

[0113] By way of example, the individual blisters shown in FIGS. 1, 4, 8, 10, 12, 14 and 16 allow a tesselation.

[0114] A further subject of the present invention is a method for producing individual blisters according to the invention.

[0115] The method according to the invention is characterized in that the individual blisters are separated off from a sheet or a web comprising a multiplicity of individual blisters. The separation can be implemented by conventional methods, such as laser cutting, mechanical cutting, punching, etching, electron beam machining, ultrasound and water jet. These and further methods are described, for example, in DIN standards 8588, 8589 and 8590.

[0116] In a particularly preferred embodiment, the individual blisters are produced from a macro blister pack, which is described in greater detail in EP15182316.8.
