may be made in any manner and take any form and may indeed severe the material along the longitudinal centerline fig1 illustrates first embodiment 10 of the invention casing 11 is generally cylindrical or tubular in shape after filling with food product see e g food product 26 shown in fig8 fig1 shows the end result of the method of the invention wherein end 12 of casing 11 has been formed into rigid loop 13 loop 13 may be secured about a hook or other fastening device to hang the food filled casing the first step in the method is to form one end of the tubular casing into a flattened portion fig2 illustrates one way of doing this wherein end 12 is formed into four longitudinal folds 18 19 20 and 21 respectively each fold comprises two layers of casing 11 for example fold 18 comprises layers 15 and 16 the folds extend radially outward from imaginary longitudinal centerline 14 of casing 11 fig3 is a cross sectional view of the casing taken along plane 3 3 of fig2 obviously merely folding the casing may be insufficient to seal the food product inside and prevent its escape through the seams of the folds for this reason it is preferable to heat seal the folds such that the individual layers of the folds melt into an integral piece fig4 is a view similar to that of fig3 after heat sealing which shows that.
