The invention relates to a plastic package for a pharmaceutical product, particularly a blister package to dispense liquids or strings, and a method of manufacturing and sterilizing said package. The blister package (1) consists of a lower base portion (2) and a cover member (3). The lower portion includes a cavity indicated generally as (4) which is advantageously formed by inclined sidewalls (5) and upstanding side walls (6) and a bottom (7) which has a circular, flat and smooth surface. The cavity (4) is surrounded by outward extending flange (8). Cover member (3) is welded completely to flange (8) around the opening of cavity (4). Cavity (4) is sized to receive a pharmaceutical product, preferably an ophthalmologic product. The inclined side walls (5) preferably have a rounded geometry to avoid sharp edges for safety reasons. The upstanding side walls (6) have preferably no rounded portions in order to stabilize the cavity ( 4) as in the contact area of the side walls (5, 6) and the cavity (4) is quite rigid.

The invention claimed is: 1. A method of manufacturing and sterilizing a pharmaceutical package wherein the package comprises a lower base portion having a cavity for containing the pharmaceutical product and a flange extending outwardly about the periphery of the cavity, the cavity being defined by a bottom surface and side wall surfaces, extending between the bottom surface and the flange, and a flexible cover sheet welded to the flange, a calibrated orifice in the bottom surface which is covered by a second cover member releasably sealed to the bottom surface around the perimeter of the orifice, the method comprising the steps: a) preparing a plastic lower film material for the lower base portion and a plastic film material for the upper film material for the cover member by locating an intermediate film between the two layers formed by the lower and upper film material for the following steam sterilization in an autoclaving chamber; b) sterilizing the packaged film material in the autoclaving chamber by a temperature of 121째 C. during 20 minutes; c) preheating the lower film material by progressively heating in three steps from 20째 C. to about 150째 C. between two hot-plates at each preheating station; d) thermoforming the lower base portion by using dies and molds with a specific temperature for the dies and molds and by regulating the temperature, the pressure and the time by computer-control; e) piercing a calibrated orifice through the bottom surface for delivering the product at the moment of use by a customer; f) closing the orifice by the second cover member which is sterilized by gamma-radiation or steam; g) filling the cavity of the lower base portion from the top with the pharmaceutical product; and h) welding the upper film onto the flange. 2. A method according to claim 1, wherein transversal holes are pressed into the intermediate film between the two layers formed by the lower and the upper film materials for the transfer of steam flow. 3. A method according to claim 1, wherein the plastic lower film material for the lower base portion is made of polypropylene and has a thickness of about 300 micrometer to about 700 micrometer. 4. A method according to claim 1, wherein the plastic upper film material for the cover member is made of a polypropylene foil material and has a thickness of about 50 micrometer to about 100 micrometer. 5. A method according to claim 1, wherein the second cover member is a Tiroff-film of a polypropylene foil with a thickness of about 50 micrometer to 100 micrometer, which is sealed onto the bottom surface. 6. A method according to claim 1, wherein temperature, pressure and surface contact for the sealing processes are regulated by computer-control. 7. A method according to claim 1, wherein steps (c) to (h) are performed under aseptic conditions. 8. A method according to claim 1, wherein the dies, the molds, piercing means, filling means and sealing means are sterilized in an autoclaving chamber or in a place with steam before being used in the thermoforming, piercing, filling and sealing steps. 9. A method according to claim 1, wherein the sealed package filled with the pharmaceutical product is transferred out of an aseptic area. 10. A method according to claim 1, wherein the method further includes a step of testing if the lower base portion is free from leakage after sealing the orifice and before filling the cavity of the lower base portion. 11. A method according to claim 1, wherein the method further includes a step of leaking testing of the package after sealing the upper film material onto the flange. 12. A method according to claim 1, further including printing product parameters onto the upper film of the package. 13. A method according to claim 12, wherein the printing is performed by using ink jet printing and/or laser printing technologies. 14. A method according to claim 1, further including cutting package-containing film material into strips of several single dose units and packing the strips of several single dose units into a secondary packaging. 15. A method according to claim 14, further including sterilizing the secondary packaging by steam or gamma-radiation before packing the strips of several single dose units into the secondary packaging.
