Package

Abstract

Package comprising a substantially cylindrical part ( 5 ), which has a bottom ( 3 ) at one end and at the other end is formed in one part with an essentially truncated cone-shaped, tapering part ( 6 ), which in the narrowest end has a closable spout ( 4 ), said cylindrical and tapering part ( 5,6 ) are formed by folding a mainly rectangular, sheet-shaped body ( 7 ) made of laminate with a plastic coating and welded together by overlapping end parts, whereby the tapering part ( 6 ) is achieved by forming and folding a number of overlapping folds, where each fold in circumferential direction has an area expanding in direction of the narrowest end. The rectangular, sheet-shaped body includes inclined cut corners ( 15, 16 ) at the end, which forms the narrowest end after folding, said corners being cut so that the tapering part ( 6 ) includes three folded layers as a maximum.

1 . Package comprising a substantially cylindrical part ( 5 ), which has a bottom ( 3 ) at one end and at the other end is formed in one part with an essentially truncated cone-shaped, tapering part ( 6 ), which in the narrowest end has a closable spout ( 4 ), said cylindrical and tapering part ( 5 ,  6 ) are formed by folding a mainly rectangular, sheet-shaped body ( 7 ) made of a laminate with a plastic coating and welded together by overlapping end parts, whereby the tapering part ( 6 ) is achieved by forming and folding a number of overlapping folds ( 8 ,  9 ,  10 ), where each fold in circumferential direction has an extent increasing in direction of the narrowest end, characterised in that the rectangular, sheet-shaped body includes inclined cut corners ( 15 ,  16 ) at the end, which forms the narrowest end after folding, said corners being cut so that the tapering part ( 6 ) includes three folded layers as a maximum. 
   
   
       2 . Package according to  claim 1 , characterised in that the spout ( 4 ) is welded or glued to the narrowest end of the tapering part ( 6 ). 
   
   
       3 . Package according to  claim 1 , characterised in that the bottom  3  is made of a separate, sheet-shaped body with a circumferential skirt ( 17 ), by which it is welded to the cylindrical part ( 5 ) of the package. 
   
   
       4 . Sheet-shaped body for making bottle-shaped packages, said body having folding lines ( 8  , 9 ,  10 ) along one of the sides for use in connection with the folding of the truncated cone-shaped part ( 6 ), characterised in that it includes inclined cut corners ( 15 ,  16 ) at both ends of the said side ( 14 ).
