DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The invention relates to packaging for pellet-shaped products, consisting of a deep-drawn element for receiving the products and a cover foil.
A deep-drawn push-through package for tablets for the purposeful removal of individual products is commercially widely distributed, wherein the deep-drawn element has a number of individual wells for receiving the tablets corresponding to the number of tablets. The push-through foil is provided with a metal foil as the cover element or a composite aluminum-metal foil and its strength is of such a size that the tablet is pushed out by pressure from the bottom toward the top on the deep-drawn well. Because of the employment of different materials for the deep-drawn foil or the cover foil, recycling of the package is possible only if the separation of the materials is performed more or less laboriously by the end user which, as experience has shown, is not the case at least right now. In addition, the arrangement of individual wells is very expensive from a material point of view if the ratio of the number of products to the packaging material is taken into consideration.
A further disadvantage of this packaging lies in that the often printed cover foil is inevitably further destroyed every time tablets are removed and the information thereon is no longer legible and therefore is useless for passing on further information regarding the respective pharmaceutical product.
PRIOR ART
U.S. Pat. No. 4,721,204 shows a packaging in accordance with the species. It is used for a magazine-like receptacle of ampuls; the cardboard cover element at one package end is embodied flap-like for opening and closing the deep-drawn element. By flipping the protruding edge of the cover element over (identified as support element), the removal opening can at least be closed again to such an extent that the remaining ampuls are secure against falling out. This "mechanical" reclosing is sufficient here, because the required sealing measures regarding the pharmaceutical active ingredient are provided by the ampuls. This packaging cannot be used for other, solid presentations of pharmaceutical articles, such as tablets, since the packaging, once opened, no longer assures a sufficient seal against dust and moisture and since the pharmaceutical effect and/or the stability of the preparation can be impaired.
This, too, is a multi-material package with the disposal problems already indicated above.
Packaging with a flap for removing the products through a removal opening and with an adhesive foil extending over the flap and at least a portion of the adjoining surface of the packaging in such a way that the removal opening can be reclosed by means of the flap, is known from DE-U-88 10 948. The packaging shown there consists of a deep-drawn element and a sealed-on cover foil, wherein the said removal opening is provided in the deep-drawn element. Since several of the pellet-shaped products, for example candy or tablets, are present without any order in the deep-drawn element, the controlled removal of the products from such packaging is not possible. With the technology used, these packagings are also made of different materials, in particular a plastic deep-drawn element and a mostly metallic cover foil and first require the separation of these materials before recycling is possible.
DE-U-88 11 951.3 shows a blister pack for small objects, for example tablets, wherein the cover foil extends strip-like over the individual wells and also consists of a metal foil, something which does not remove the problem of disposal. To be able to achieve reclosing of individual wells, places free of adhesive are provided in this area, and the adhesive for connecting the deep-drawn element with the cover foil is intended to reusable.
This solution does not materially reduce the material outlay, but increases the production outlay, since it is necessary to produce the adhesive-free portion of the strips of the cover foil in a precise manner and to glue them in the exact positions on the deep-drawn e
