The present invention relates to an encapsulated blister package, which is used as consumer package for medicines especially in the form of tablets, pills and capsules.
A blister package typically comprises a cover part of viscous, flexible, transparent plastics, which is laminated to a base of brittle, film-type material, such as foil paper. The plastic cover has blister-like protrusions, forming cavities between the cover and the base, each of them containing one packed article, such as a tablet or similar. The plastic material of the cover is sufficiently rigid so that the blisters would maintain their shape in the normal state, but yield when pressing the blister with a finger so that the tablet or other similar article can be pressed out of the package through the breaking base.
The present blister packages used as medicine packages are typically rectangular, comprising tablets, pills or similar arranged in vertical and horizontal lines. The consumer package consists of one or several such blister packages packed, for example, into a casing of cardboard.
Extracting a tablet or similar from the medicine package described above requires that the casing be opened, the blister package be pulled out of the casing, the tablet be removed from the blister package, and finally, the blister package be fitted back into the casing.
The object of the invention is the achieve an encapsulated blister package, from which a tablet or similar can be extracted more simply and effortessly than at present. It is characteristic of the package of the invention that it has a flat, outer casing open at least from one side, and at least partly extractable inner part, which comprises a disc formed as a blister package fitted rotatably onto a base, which is partly open below the disc so that the product to be released from the disc by pressing the blister can be removed from the package.
The structural basis for the encapsulated package of the invention has been a CD package disclosed in the patent specification U.S. Pat. No. 6,032,795, which consists of an outer casing and a partly extractable inner part supporting the CD. Instead of a CD, the package of the invention comprises a discoidal blister package, which contains tablets or other similar articles individually packed into blister-like cavities. In distinction from the CD package of the said specification, the disc is not intended to be removed from the base, but it is essential that the disc rotates in relation to the base so that it is possible to bring the tablet to be released at any given time into a position, in which it can be released from the disc by pressing.
The disc containing the tablets or other similar articles can be formed as such in a conventional way from a blister sheet of flexible plastic and a base of bristle material, such as foil paper, which breaks when the tablet is removed by pressing.
The base belonging to the extractable part of the package can consist of a sheet, which most suitably is closed, exclusive of an outlet opening formed into it, at which the tablet to be extracted from the package can be placed by rotating the disc and through which the tablet pressed out from the disc can be removed from the package. If the tablets are arranged in the disc as a circular line or ring, the outlet opening can be relatively small, covering only the area of the tablet to be released and the area immediately surrounding it. In this case, the tablets can be brought to the outlet opening by rotating the disc, and they can be pressed out of the disc one at a time. However, it is also possible to place the tablets to the disc in another way, for example, as several concentric arcs or rings, or possibly as a spiral surrounding the centre of the disc, in which case the area of the disc will be more efficiently used in the package. In these cases the base can be provided with a longitudinal outlet opening in the direction of the disc radius, to which each tablet can be brought for release irrespective of the location of the tablets on the disc.
With the exception of the defined outlet opening, the closed, unrotatable base onto which the disc is articulated, forms a solid structure, from which it is easy to release the tablets or other similar packed articles. Nevertheless, also other kinds of structures are possible within the scope of the invention. It is essential that the base, onto which the disc is supported, is open in such a way that it does not prevent the release of the tablet brought to this open area from the disc. According to one embodiment of the invention, the extractable base comprises an unrotatable frame, which supports two superimposed discs rotating in relation to the frame and to each other, the upper one forming the blister package containing the tablets or other similar articles, and the lower one being provided with an outlet opening making it possible to press off the tablet. In this case, releasing the tablets requires the matching of the tablet and the outlet opening by rotating the superimposed discs in relation to each other.
According to a further embodiment of the invention the tablets or other similar articles are arranged on the disc forming the blister package so that a sector totally free of tablets remains in the disc. The idea here is that, when manufacturing the packages, the said sector is placed at the outlet opening in the otherwise closed base so that it is not enough to extract the base and disc out from the casing to release the tablet, but the disc has to be additionally rotated in relation to the base before the tablet can leave the package. This, as also the said solution consisting of two superimposed discs, are suitable for medicine packages, especially from the point of view of child safety.
The disc can be rotatably connected to the base by articulating the disc to the base from its middle section. The base can comprise a joint pin, around which the disc rotates by pressing by a finger.
Alternatively, the extractable inner part can be provided with a retainer, which extends onto the disc from the side of the base and keeps the disc in place on the base. Such a retainer can be made, for example, as a ring-shaped rim encircling the circumference of the disc so that the edge of the disc is left between the sheet-shaped base and the rim. The said joint between the disc and the base will not be needed in this embodiment, but the disc can freely rest on the base and be rotated by pressing by fingers.
The invention can also be advantageously applied so that a projection or some other hindrance is placed to the disc and/or base, allowing the disc to rotate to one direction only. One implementation is to provide the said rim surrounding the disc with a tongue extending towards the centre of the disc, the tongue having at least one fin extending down towards the disc and turning to only one direction, which the blister in the disc can pass in the said turning direction, but not in the opposite direction of rotation of the disc. This solution helps the consumer to release the tablets or similar from the package in the order, in which they are located on the disc.
As the CD casing according to the said specification U.S. Pat. No. 6,032,795, also the encapsulated package of the invention, the disc excluded, can be manufactured of package cardboard, which is an inexpensive recyclable material for disposable consumer packages to be disposed of after the use.
The invention shall next be explained in more detail by means of examples, referring to the enclosed drawings, in which

The encapsulated medicine package of the invention illustrated in
From one side, the sheet-shaped base 5 has been folded so that, in a closed package, in which the inner part 2 is pressed into the casing 1, the fold 10 forms the lateral edge closing the open edge 4 of the casing. From the sectional view 3 it can be seen that the opposite edge of the base 5 is provided with the similar fold 11, which in cooperation with the inner fold 12 on the open edge 4 of the casing 1 prevents the inner part 2 from loosening from the casing in connection with the extraction. This ensures that the package stays in one piece when used, which is the central precondition for its effortless use. The base 5 can be manufactured of a sheet of package cardboard by folding the sides 10, 11 and by die cutting the outlet opening 9 for the tablets.

It is obvious for those skilled in the art that the embodiments of the invention are not limited to those disclosed as examples above, but they may vary within the scope of the following patent claims. For example, it is possible to restrict the output of the inner part 2 from the casing 1 so that the disc 7 will come into view only in part. A disc, which has been extracted out from the casing approximately halfway, is still easily rotatable with fingers, while keeping the package more compact and thus easier to handle.
