ABSTRACT OF THE DISCLOSURE The present invention relates to a unique method for packaging a product in individual packets constructed of a sheet of flexible material. In the method of the present invention, a sheet of flexible packaging material is formed into a generally U-shaped channel having spaced apart vertical sidewalls. The facing surfaces of the sidewalls are sealed at vertically spaced apart locations to define a plurality of open top packets. A predetermined amount of a flowable product is introduced into each of the open top packets. Next, the upper corner portions of each individual packet are sealed and a predetermined portion is cut from each upper corner. The upper corner portions of each packet then are pulled away from one another in a generally horizontal direction to urge the spaced apart upper marginal edges of the sidewalls of the packet toward one another. After the upper corner portions have been pulled away from one another, the upper marginal edges of the packets are sealed together to close the packet. The present invention also concerns an apparatus for packaging a product in individual packets, and a novel packet construction.
