Abstract

A tetrahedral-shaped pouch can be opened by tearing from a cut in a first lateral sealing edge and along a longitudinal sealing substantially perpendicular to the first lateral sealing edge to conveniently access non-liquid food contents, such as seeds or nuts. A short longitudinal cut can be made into but not all the way through the first lateral sealing edge, adjacent where the longitudinal sealing is positioned on the first lateral sealing edge. When opening the pouch, by initiating a tear starting at the cut, the packaging material will tear along, but not cross the longitudinal sealing, since the longitudinal sealing is formed from an overlapped and doubly thick section of packaging material. The pouch will therefore open, on at least one side of the tetrahedron, along a predictable tear line following the longitudinal sealing, to form a bowl-shaped receptacle from which the contained food product can be conveniently accessed.

Claims20

Dependent claims

A pouch for a food product comprising:

a side wall comprising a tubular section of material that has been formed by bringing together, overlapping and sealing together longitudinal edge sections of a sheet of packaging material to form a longitudinal sealing;
a first sealing edge extending laterally across a first flattened and cut end section of the tubular section of material and arranged substantially orthogonally to the longitudinal sealing;
a second sealing edge extending laterally across a second flattened and cut end section of the tubular section of material opposite the first flattened and cut end section of the tubular section of material, the second sealing edge arranged substantially orthogonally to the first sealing edge and to the longitudinal sealing;
a notch in the first sealing edge adjacent the longitudinal sealing;
and
a tear area for generating an opening starting from the notch in the first sealing edge and having one border extending substantially along the longitudinal sealing.
