Method for filling bottles and filler cap

Abstract

There is provided a method of filling a bottle, in particular a PET bottle. A filler cap having a first and a second end ( 11, 12 ) is fitted on to the bottle head. In that case the second end ( 12 ) of the filler cap is arranged on the bottle head. A filler head is fitted on to or into a first end ( 11 ) of the filler cap. The bottle is sterilised by the filler head which is introduced into the first end ( 11 ) of the filler cap. The bottle is then filled by the filler head introduced into the first end ( 11 ). The first end ( 11 ) of the filler cap is welded to close the bottle while the filler head is in the first end ( 11 ) of the filler cap.

1 . A method of filling a bottle, in particular a PET bottle, comprising the steps:
 applying a filler cap having a first end and a second end ( 11 ,  12 ) to the bottle head,   introducing a filler head into the first end ( 11 ) of the filler cap, the second end ( 12 ) of the filler cap being arranged on the bottle head,   sterilising the bottle by the filler head introduced into the first end of the filler cap,   filling the bottle through the filler head which is introduced into the first end ( 11 ), and   welding the first end ( 11 ) of the filler cap to close the bottle while the filler head is in the first end of the filler cap.   
     
     
         2 . A filler cap for filling and closing bottles
 comprising a first end ( 11 ) for receiving a filler head and a second end ( 12 ) for fixing on a bottle head of a bottle to be filled;   wherein the first end ( 11 ) is of such a configuration that a filler head can be introduced into the first end ( 11 ) of the filler cap to sterilise and fill the bottle and it is weldable to close the bottle.   
     
     
         3 . A filler cap as set forth in  claim 2  wherein the second end is of a circular configuration and has a groove ( 13 ) for receiving a bottle head. 
     
     
         4 . A filler cap as set forth in  claim 2  or  claim 3  wherein the first end ( 11 ) is of a slot-shaped configuration in cross-section and projects beyond the second end by a predetermined amount.
