Blister packaging and method for the temporary storage of products

Abstract

Embodiments of the invention are directed toward blister packaging for the temporary storage of products, specifically medicaments, as well as methods for temporarily storing medicaments in blister packaging. The blister packaging includes a number of receiving compartments that are covered by a two-layer film for at least one product unit in each case. Perforated sections in one of the film layers include a tear-open line when a mechanical force is applied to the film, via the product unit. One of the film layers provides an impermeable layer while the second layer prevents unintended opening.

1 . Blister packaging for the temporary storage of products, in particular medicaments, which has a number of receiving compartments, which are occluded by a film in each case, for at least one product unit in each case, which film is formed by a first and a second layer of film, wherein perforated sections constructed in the second layer of film, which form a defined tear-open line in the film when a mechanical force is exerted on said film via the product unit, are associated with the receiving compartments in each case, and wherein the first and second layers of film are bonded to one another,
 wherein the perforated sections form non-closed tear-open lines which are adapted to the shape and/or size of the product unit received in a receiving compartment.   
   
   
       2 . Blister packaging according to  claim 1 , wherein the perforated sections form a U-shaped tear-open line. 
   
   
       3 . Blister packaging according to  claim 1 , wherein the perforated sections are formed by two separate, mutually complementary sections. 
   
   
       4 . Blister packaging according to  claim 1 , wherein the first layer of film occludes the receiving compartments and the second layer of film is constructed on the first layer of film. 
   
   
       5 . Blister packaging according to  claim 1 , wherein the first layer of film is constructed from a material which is impermeable to air and water vapour. 
   
   
       6 . Blister packaging according to  claim 1 , wherein the first layer of film is constructed from aluminum or plastic film. 
   
   
       7 . Blister packaging according to  claim 1 , wherein the first layer of film has a thickness of 0.002 mm to 0.05 mm. 
   
   
       8 . Blister packaging according to  claim 1 , wherein the second layer of film is constructed from a mechanically stiff material. 
   
   
       9 . Blister packaging according to  claim 1 , wherein the second layer of film is constructed from paper material, cardboard material or plastic material. 
   
   
       10 . Blister packaging according to  claim 1 , wherein the second layer of film has a thickness of 0.005 mm to 0.5 mm. 
   
   
       11 . Blister packaging according to  claim 1 , wherein a depth of the perforated sections corresponds to a depth of the second layer of film. 
   
   
       12 . Blister packaging according to  claim 1 , wherein the second layer of film has a machine-readable identifier on its outer side for product identification. 
   
   
       13 . Blister packaging according to  claim 1 , wherein the second layer of film has a dark surface. 
   
   
       14 . Blister packaging according to  claim 1 , which blister packaging is constructed as an endless strip-type blister pack. 
   
   
       15 . Method for the temporary storage of products, in particular medicaments, in a number of receiving compartments in a blister packaging which are occluded by a film in each case, which film is formed by first and second layers of film which are bonded to one another, said method comprising the following:
 mechanically filling the receiving compartments with at least one product unit in each case;   occluding the receiving compartments by the film;   providing the second layer of film with perforated sections in the region of the receiving compartments, which perforated sections form a defined tearing-open line in the film when a mechanical force is exerted upon said film via the product unit, and said perforated sections form non-closed tearing-open lines which are adapted to the shape and/or size of the product unit received in a receiving compartment; and   mechanically removing the products from the receiving compartments as a result of the exerting of a mechanical force on the film via the product unit, the film tearing open along the perforated sections.   
   
   
       16 . Method according to  claim 15 , wherein the perforated sections form a U-shaped tearing-open line. 
   
   
       17 . Method according to  claim 15 , wherein the perforated sections are formed by two separate, mutually complementary sections. 
   
   
       18 . Method according to  claim 15 , wherein providing the second layer of film with perforated sections is performed by a laser beam. 
   
   
       19 . Method according to  claim 15 , wherein the blister packaging is constructed as an endless strip-type blister pack. 
   
   
       20 . Method according to  claim 15 , wherein mechanically removing the products from the receiving compartments is performed by cyclically controlled plungers associated with each of the receiving compartments. 
   
   
       21 . Method according to  claim 15 , wherein providing the second layer of film with perforated sections is carried out prior to mechanically filling the receiving compartments with at least one product unit. 
   
   
       22 . Method according to  claim 15 , wherein a number of different medicaments can be packed away, one after another, in respective endless strip-type blister packs for temporary storage.
