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 collapsible, sanitary dispenser pouch formed from thin films of sheet material for holding between 24 and 30 liquid ounces of viscous product, comprising in combination: a pair of substantially rectangular heat sealable films having two ends and two sides, heat sealed together along said two sides by substantially straight side seals; a first of said two ends being heat sealed together so as to form a bottom, substantially straight cross seal; a portion of the other of said two ends being heat sealed together so as to form a top cross seal having a specifically formed sealed outlet spout portion therein centrally disposed between said substantially straight side seals; a hollow internal chamber formed between said substantially straight side seals, said bottom substantially straight cross seal and said top cross seal to hold said between 24 and 30 liquid ounces of viscous product therein; said top cross seal including sealed portions formed between said pair of substantially rectangular heat sealable films adjacent to and angularly disposed between said specifically formed sealed outlet spout portion and said substantially straight side seals to form angled internal walls in said hollow internal chamber extending at angles of approximately 15 degrees with respect to said substantially straight side seals; said specifically formed sealed outlet spout portion including an outlet tip and sloped internal wall portions which are sloped at an angle of approximately 30 degrees with respect to a centerline of said dispenser pouch, which centerline is disposed parallel to said substantially straight side seals and passes centrally through said dispenser pouch, to form a funnel-shaped interior area in said specifically formed sealed outlet spout portion; a substantially smooth, rounded edge formed between said angled internal walls and said funnel-shaped interior area; a pair of openings formed in and passing through said pair of substantially rectangular heat sealable films in a flattened area of said dispenser pouch formed above said sloped internal wall portions and between said specifically formed sealed outlet spout portion and perforations of a tear-off strip, away from said hollow internal chamber, toward said other of said two ends; and said tear-off strip being formed in said other of said two ends, away from said hollow internal chamber, above said pair of openings, by a plurality of perforations formed therein and extending across said other of said two ends, up to but not across said outlet tip of said specifically formed sealed outlet spout portion, which tear-off strip, when removed will also remove said outlet tip to unseal said specifically formed sealed outlet spout portion and allow controlled dispensing therethrough of said between 24 and 30 liquid ounces of viscous product from said hollow internal chamber, around said substantially smooth, rounded edge and out through said funnel-shaped interior area.
