Flat container

Abstract

A flat container ( 1 ) with a container bottom ( 3 ) is provided having a peripheral edge ( 3′ ) in which a step ( 13 ) is formed. A film ( 19 ) with a peel-away tab ( 21 )is sealed or bonded to the step. Under the film ( 19 ) that advantageously has an air-tight and water vapor-tight construction, an optimum product space ( 23 ) for the product can be obtained.

1 . A flat container ( 1 ) comprising a container top ( 3 ) and a container bottom ( 5 ) that are connected to each other in an articulated way by at least one hinge ( 7 ), on the container bottom ( 3 ) a peripheral step ( 13 ) is constructed at the top of the container bottom as a sealing surface ( 15 ) for a sealing a film ( 19 ) to form an air-tight seal of a filling space ( 23 ) in the container bottom ( 3 ). 
   
   
       2 . The flat container according to  claim 1 , wherein the peripheral step ( 13 ) is formed by a peripheral bead directed inwardly on the container bottom ( 3 ). 
   
   
       3 . The flat container according to  claim 1 , wherein a sealing surface ( 15 ) of the step ( 13 ) is arranged at a distance to a peak S on a top edge of the container bottom. 
   
   
       4 . The flat container according to  claim 3 , wherein an adhesive is applied on the sealing surface ( 15 ) of the step ( 13 ) or that an inside of the lower container part ( 3 ) and the bottom side of the film ( 19 ) are coated with a sealable coating. 
   
   
       5 . The flat container according to  claim 3 , wherein the step ( 13 ) that forms the sealing surface ( 15 ) lies essentially completely within a side wall ( 3 ″) of the container ( 1 ). 
   
   
       6 . The flat container according to  claim 5 , wherein outside of the sealing surface ( 15 ), a peripheral edge ( 31 ) is attached and is adapted to contact the cover part ( 5 ) and to center the film ( 19 ). 
   
   
       7 . The flat container according to  claim 1 , wherein a central part ( 25 ) of the upper container part ( 5 ) is lowered. 
   
   
       8 . The flat container according to  claim 7 , wherein, for a closed container ( 1 ), the central part ( 25 ) of the upper container ( 5 ) lies at a small distance from the film or contacts the film.
