BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a device made of a plastic material for pushing tablets out of a blister pack.
2. Description of Prior Art
Blister packs are often used for dispensing tablets, since they are easily visible and allow controlled dispensation. Such blister packs consist of a deep-drawn plastic foil with respectively one raised portion, in which respectively one tablet can be positioned, which is covered by a welded-on continuous metal foil. To remove the tablets, the package must be held in a hand and the tablet must be pushed through the metal foil by pressing on the raised portion in the plastic foil, with a thumb.
The metal foil often is a printed aluminum foil, but coated aluminum foils, plasticized aluminum foils and plastic foils vapor-plated with a metal coating are also used. The force needed for removing a tablet is a function of the flexural strength of the deep-drawn, mostly transparent plastic foil and also of the toughness of the cover foil.
Because of their illness, some patients have difficulties pushing the tablets out of the blister pack. This applies in particular to patients with Parkinson's disease and those with rheumatic afflictions of the hands. Often such patients are already overtaxed by simple manipulations and have to rely on the help of third parties.
A device for the rapid removal of all tablets from a blister pack is known from U.S. Pat. No. 4,384,649. A base plate has depressions, onto which the blister pack can be placed with the raised portions down, wherein a pivotal stamping plate perforates the cover plate above all raised portions.
Both European Patent Reference 0,547,426 and U.S. Pat. No. 3,630,171 show devices suitable for the individual removal of tablets from blister packs, which have a lower base plate with ribs oriented toward a bearing surface and defining a level of placement with a height greater than a thickness of the tablets to be discharged, wherein the base plate has openings corresponding to a grid of raised portions in the blister pack.
While with European Patent Reference 0,547,426 the cover plate remains closed during the removal of tablets, the same as with the invention, it is necessary with U.S. Pat. No. 3,630,171 to open it. The first-mentioned solution has a connecting link guide in the cover, in which a tappet is slidingly guided.
SUMMARY OF THE INVENTION
It is one object of this invention to provide a device of the type mentioned above, so that handicapped patients can remove a tablet from the blister pack without the assistance of others.
This object is attained by a device with the characteristics mentioned in this specification which includes a description of advantageous embodiments of this invention.
BRIEF DESCRIPTION OF THE DRAWINGS
A preferred embodiment of the subject of the invention is represented in detail in the attached drawings and will be explained by means of the following description wherein:
FIG. 1 is a top view of an opened device with a blister pack inserted;
FIG. 2 is a vertical sectional view taken through a closed device with a blister pack inserted;
FIG. 3 is a side view of the closed device with a view on a catch;
FIG. 4 is a vertical sectional view taken perpendicular to a longitudinal edge of the device;
FIG. 5 is a top view of a blister pack inserted, in a closed state; and
FIG. 6 is a schematic drawing showing use of a device to push a tablet out of the blister pack.
DESCRIPTION OF PREFERRED EMBODIMENTS
The device in accordance with this invention essentially comprises a base plate 10 and a cover plate 20, pivotally connected therewith. Preferably the cover plate 20 is integrally connected with the base plate 10, and both plates 10, 20 are pivotal with respect to each other about a pivot axis 21. In the present example the pivot axis 21 is constituted by two hinges 22. The hinges 22 are designed as film hinges. A blister pack 2 is shown resting on the base plate 10. The blister pack 2 comprises a deep-drawn plastic foil 3, in which raised portions
