Method for filling a blister packaging with liquid, and blister packaging with a cavity for filling with liquid

Abstract

A method for filling a cavity, of a packaging, particularly a blister packaging, with a liquid and a packaging suitable for this purpose are proposed. The cavity is completely filled with the liquid by an acceleration force or by continuous throughflow.

1 . A method for filling a cavity ( 2 ) in a packaging ( 1 ), with a liquid ( 3 ), wherein the cavity ( 2 ) is formed between a support ( 4 ) and a cover ( 5 ), 
       characterised in that
 between the support ( 4 ) and cover ( 5 ) a supply region connected to the cavity ( 2 ) is formed and in that after being covered by the cover ( 5 ) the cavity ( 2 ) is filled with the liquid ( 3 ) through the supply region at least substantially completely and with no gas bubbles by an acceleration force (B) or by continuous throughflow (D). 
 
     
     
         2 . The method according to  claim 1 , characterised in that the supply region and, if present, a discharge region adjoining the cavity ( 2 ), formed between the support ( 4 ) and cover ( 5 ), for gas ( 8 ) escaping or displaced from the cavity ( 2 ) and/or for the liquid ( 3 ) that has flowed through the cavity ( 2 ) are closed off after the filling of the cavity ( 2 ). 
     
     
         3 . The method according to  claim 1 , characterised in that between the support ( 4 ) and cover ( 5 ) is formed an additional cavity ( 2 A) and in that the liquid ( 3 ) is supplied from the additional cavity ( 2 A) to the cavity ( 2 ) that is to be filled and gas ( 8 ) is displaced or is able to escape from the cavity ( 2 ) that is to be filled into the additional cavity ( 2 A), particularly through a discharge region formed between the support ( 4 ) and cover ( 5 ). 
     
     
         4 . The method according to  claim 3 , characterised in that the packaging ( 1 ) is sealed in fluidtight manner after partial filling of the additional cavity ( 2 A) and in particular of the cavity ( 2 ) that is to be filled with liquid ( 3 ) and then the cavity ( 2 ) that is to be filled is filled with the liquid ( 3 ) at least substantially completely and with no gas bubbles. 
     
     
         5 . The method according to  claim 1 , characterised in that gravitational force is used as the acceleration force (B). 
     
     
         6 . The method according to  claim 1 , characterised in that a centrifugal force acting on the liquid ( 3 ) is used as the acceleration force (B). 
     
     
         7 . The method according to  claim 1 , characterised in that the liquid ( 3 ) is circulated in order to flow through (D) the cavity ( 2 ) that is to be filled. 
     
     
         8 . The method according to  claim 1 , characterised in that the liquid ( 3 ) is passed in series through a plurality of cavities ( 2 ) to be filled. 
     
     
         9 . The method according to  claim 1 , characterised in that a plurality of cavities ( 2 ) to be filled are connected in parallel to the supply region and the liquid ( 3 ) is passed through them in parallel. 
     
     
         10 . Packaging ( 1 ), having at least one cavity ( 2 ) to be filled with a liquid ( 3 ),
 the packaging ( 1 ) comprising a support ( 4 ) and a cover ( 5 ), between which the cavity ( 2 ) is formed,   
       characterised in that
 the packaging ( 1 ) comprises a supply region and discharge region attached to the cavity ( 2 ), the two regions being formed between the support ( 4 ) and cover ( 5 ), so that after being covered by the cover ( 5 ) the cavity ( 2 ) can be filled with the liquid at least substantially completely and with no gas bubbles by an acceleration force (B) or by continuous throughflow (D), wherein 
 the packaging ( 1 ) comprises an additional cavity ( 2 A) and liquid ( 3 ) can be supplied from the additional cavity ( 2 A) to the cavity ( 2 ) that is to be filled, while gas ( 8 ) can be displaced or can escape from the cavity ( 2 ) that is to be filled through the discharge region into the additional cavity ( 2 A), or 
 a plurality of cavities ( 2 ) that are to be filled are formed between the support ( 4 ) and cover ( 5 ) and these are jointly connected to the supply region in parallel and/or in series. 
 
     
     
         11 . The packaging according to  claim 10 , characterised in that the supply region and the discharge region are formed by a common channel ( 7 ). 
     
     
         12 . The packaging according to  claim 10 , characterised in that the supply region and the discharge region are formed by separate channels ( 7 ,  10 ). 
     
     
         13 . The packaging according to  claim 10 , characterised in that the supply region and the discharge region is formed by the additional cavity ( 2 A), which immediately adjoins the cavity ( 2 ) that is to be filled or surrounds the latter. 
     
     
         14 . The packaging according to  claim 10 , characterised in that the supply region and the discharge region are outwardly open when the cavity ( 2 ) is covered, for filling the cavity ( 2 ). 
     
     
         15 . The packaging according to  claim 10 , characterised in that the packaging ( 1 ) is at least substantially flat in configuration, while in particular the cavity (cavities) ( 2 ,  2 A), the supply region and the discharge region are arranged at least substantially on a flat side of the packaging ( 1 ) or in a plane (E).
