A pouch for holding viscous food product for dispensing from a specific hand held or similar type dispenser, is formed so as to include a tear strip to open a funnel-shaped, centrally disposed outlet spout formed to be sealingly held in the specific dispenser. The pouch includes a pair of alignment/holding openings formed on either side of the outlet spout for securing the pouch in a fixed position in the dispenser. The invention also includes head seal tooling having a pair of heated jaws which are brought together to simultaneously form the bottom seal of a top unfilled, pouch and the outlet spout and angularly disposed top seals of a filled lower pouch, while at the same time forming perforations for the tear strip, the pair of openings in the lower pouch and cutting-off the formed, filled and sealed lower pouch from the upper pouch.

A head seal means for forming a collapsible dispenser pouch from streams of thin heat sealable film sheet material passing through a form, fill and seal packaging machine and between said head seal means; said head seal means comprising a first opposed elongated jaw and a second opposed elongated jaw; each of said first and second opposed elongated jaws having a front surface and a rear surface; each front surface of said first and second opposed elongated jaws including heating means and means for first forming a bottom cross seal on said collapsible dispenser pouch and then forming a bottom cross seal on a further pouch attached to said collapsible dispenser pouch and a top cross seal on said collapsible dispenser pouch; said front surface of said first opposed elongated jaw including an elongated cross seal portion and an elongated cut-off receiving recess extending along the entire length thereof; said cross seal portion coacting with said streams of thin heat sealable film material and a corresponding elongated cross seal portion extending along the entire length of said front surface of said second opposed elongated jaw to form said bottom cross seal on said further pouch and said top cross seal on said collapsible dispenser pouch, when said front surfaces of said first and second opposed elongated jaws are brought together; said front surface of said first opposed elongated jaw, including a pair of openings having a punch reciprocally mounted therein for forming a pair of alignment openings in said collapsible dispenser pouch and a slotted opening through which a multi-bladed perforator slides to form a plurality of perforations on said collapsible dispenser pouch; said front surface of said second opposed elongated jaw, including a pair of recessed holes to receive the ends of said punches when they are reciprocated and a slotted recess to receive the ends of said multi-bladed perforator; said front surface of said second opposed elongated jaw including an elongated opening formed therein across from and cooperating with said elongated recess formed in said front surface of said first opposed elongated jaw; and a cut-off blade, reciprocally mounted in said elongated opening in said second opposed elongated jaw to cut-off said collapsible dispenser pouch from said further pouch when said cut-off blade passes through said heat sealed films into said elongated recess in said first surface of said first opposed elongated jaw; whereby, said head seal means simultaneously forms said top and bottom cross seals on said collapsible dispenser pouch and said further pouch attached to said collapsible dispenser pouch, cuts-off said collapsible dispenser pouch from said further pouch, and forms an outlet spout, a pair of alignment openings and a tear-off strip on said collapsible dispenser pouch.
