Packaging for pharmaceutical products and method and device for its production

Abstract

The device for the production of a packaging for pharmaceutical products includes a forming station for forming troughs in a nonstretchable cover sheet in a stepwise, individual, successive manner, and further includes a transport device for laying the formed cover sheet onto a bottom sheet. This bottom sheet has pockets, which serve to hold the pharmaceutical products, and webs arranged between the pockets, and at least portions of some of the webs have ridges corresponding to the shape of the troughs in the cover sheet. The device further includes a sealing station for sealing the cover sheet to the bottom sheet. This sealing station has two sealing plates shaped in correspondence with the troughs in the cover sheet, thus resulting in the sealing of the cover sheet to the bottom sheet also in the area of the ridges of the bottom sheet.

1 . A device for the production of a packaging for pharmaceutical products, comprising:
 a forming station for forming troughs in a nonstretchable cover sheet in a stepwise, individual, successive manner;   a transport device for laying the formed cover sheet onto a bottom sheet, the bottom sheet comprising pockets, which serve to hold the pharmaceutical products, and webs arranged between the pockets, wherein at least portions of some of the webs comprise ridges corresponding to the shape of the troughs in the cover sheet; and   a sealing station for sealing the cover sheet to the bottom sheet, the sealing station comprising two sealing plates shaped in correspondence with the troughs in the cover sheet, thus resulting in the sealing of the cover sheet to the bottom sheet also in the area of the ridges of the bottom sheet.   
     
     
         2 . The device according to  claim 1 , further comprising:
 an unwinding device for partially unwinding a roll of a cover sheet material,   a cutting device for cutting off a cover sheet from the roll, and   a feed mechanism for gripping and transporting the cut cover sheet to the forming station.   
     
     
         3 . The device according to  claim 1 , wherein the forming station for the cover sheet comprises first and second forming tools, which are movable toward and away from each other, wherein the second forming tool comprises stamping dies, which act successively on the cover sheet, and the first forming tool comprises recesses corresponding to the shape of the stamping dies. 
     
     
         4 . The device according to  claim 3 , wherein the stamping dies are arranged in a row of graduated height and are pneumatically pretensioned. 
     
     
         5 . The device according to  claim 1 , wherein the first forming tool comprises a suction device for the cover sheet. 
     
     
         6 . The device according to  claim 5 , wherein the first forming tool is part of the transport device and is rotatable around a vertical axis located outside the first forming tool. 
     
     
         7 . The device according to  claim 1 , further comprising a spot-fastening device for temporarily fastening the cover sheet to the bottom sheet, the spot-fastening device being arranged upstream of the sealing station and comprising several heating pins.
