Container for filling material and method for the production thereof

Abstract

A container ( 1 ) for filling material and a method for processing gusseted tubular films ( 4 ), wherein the container ( 1 ) has a container body ( 2 ) made of a tubular film ( 4 ) provided with gussets ( 3 ) which comprises an inner volume for receiving a filling material. There is an end seam ( 5 ) on a first end ( 12 ) of the container body ( 2 ), and in the area of the gussets ( 3 ) on the container corners ( 8 ), corner seams ( 7 ) are provided which respectively extend through two layers ( 13 a, 13 b ) of the gussets ( 3 a, 3 b ) in order to separate the container corner area ( 8 ) from the inner volume. On at least one container corner ( 8 ), at least one opening ( 9 ) is provided which extends through the layers ( 13 a, 13 b ) of the gusset ( 3 a, 3 b ) and which is separated from the inner volume of the container body ( 2 ) such that, thanks to the corner seams ( 7 ) and the end seam ( 5 ) and the opening ( 9 ), a carry device ( 11 ) is formed which allows a finger hold on the carry device ( 11 ) for a person carrying the container.

       2 . The container according to  claim 1 , wherein the container body ( 2 ) substantially consists of a thermoplastic material. 
   
   
       3 . The container according to  claim 1 , wherein a head seam ( 5 ) is provided at the second end ( 6 ) of the container body ( 2 ). 
   
   
       4 . The container according to  claim 1 , wherein in the region of the end seam the corner seam extends at a right angle to the end seam to enlarge the area welded off. 
   
   
       5 . The container according to  claim 1 , wherein each container corner ( 8 ) is provided with openings ( 9 ). 
   
   
       6 . The container according to  claim 1 , wherein the opening ( 9 ) in at least one container corner ( 8 ) is configured as at least one cut or perforation and/or wherein at least one opening ( 9 ) is configured polygonal, rounded, round, oval, or crescent- or banana-shaped. 
   
   
       7 . The container according to  claim 1 , wherein at least one end seam ( 5 ,  10 ) extends continuously over the entire width of the container body. 
   
   
       8 . The container according to  claim 1 , wherein a carrying device ( 11 ) comprises at least two openings ( 9 ). 
   
   
       9 . A filling system for filling containers ( 1 ), in particular for filling bags,
 comprising a package manufacturing device at which the packages ( 1 ) to be filled are manufactured from a gusseted tubular film ( 4 ), which are provided with an end seam ( 5 ,  10 ) and corner seams ( 7 ) extending through two layers each in the area of the gussets ( 3 ) at the container corners ( 8 ) to obtain roughly rectangular packages ( 1 ) after filling, and to separate the area of the respective container corner ( 8 ) from the inner volume, and comprising a filling system at which the containers ( 1 ) are filled with a filling material,   and comprising a package closing device at which the filled packages ( 1 ) are closed, characterized by a device which manufactures at least one opening ( 9 ) in the area of at least one container corner ( 8 ) of the container ( 1 ) extending through the layers ( 13   a ,  13   b ) of the gusset ( 3 ) of the container ( 4 ) and being separated from the inner volume, such that a carrying device ( 11 ) is formed on the package ( 1 ) by means of the corner seams ( 7 ) and the end seam ( 5 ,  10 ) and the opening ( 9 ), so as to allow a person carrying the filled package ( 1 ) to obtain a finger hold on the carrying device ( 11 ).   
   
   
       10 . The filling system according to  claim 9 , wherein the device comprises a cutting or punching tool. 
   
   
       11 . A method for processing tubular film ( 4 ) provided with gussets ( 3 ) wherein at least the following steps are carried out:
 A tube section is separated off the gusseted tubular film ( 4 ) which is suitable to manufacture a container ( 1 );   The tube section is provided with an end seam ( 10 ) at a first end ( 12 );   In the areas of the gussets ( 3 ) corner seams ( 7 ) are manufactured at the container corners ( 8 ) at least at the first end ( 12 ) for the filled package ( 1 ) to assume a rectangular structure wherein the corner seams ( 7 ) partition the container corners ( 8 ) off the inner volume provided for the filling material;   At least at one container corner ( 8 ) at least one opening ( 9 ) is manufactured through the layers ( 13   a ,  13   b ) of the gussets ( 3 ) of the gusseted tubular film ( 4 ) such that a carrying device ( 11 ) is formed by way of the corner seams ( 7 ) and the end seam ( 5 ,  10 ) and the opening ( 9 ), allowing a person carrying the filled package ( 1 ) a finger hold on the carrying device ( 11 ).
