Abstract
A dispenser system having a substantially large pouch (20) for holding a substantially large amount of viscous food product for dispensing from a dispenser (122). The pouch is formed so as to include a tear strip (38) to open a funnel-shaped, centrally disposed outlet spout (24) and to be sealingly held in the dispenser. The pouch may include a pair of alignment/holding openings (32, 34) formed on either side of the outlet spout for aligning the pouch in a preferred position in the dispenser, so that a piston-type extruding member (136) may pressurize and dispense predetermined size shots of viscous food product therefrom.
Claims13
A dispenser system for dispensing viscous material from a collapsible pouch fabricated of flexible film material whereby said collapsible pouch is collapsible in an accordion fashion, comprising:
- a dispenser including a cylinder-type housing means for holding said collapsible pouch, said cylinder-type housing means having an opening at one end and being substantially elliptical in cross-section;
- a substantially elliptically shaped piston-type extruding member movable in said cylinder-type housing means;
- and
- means for moving said substantially elliptically shaped piston-type extruding member relative to said cylinder-type housing means for advancing said substantially elliptically shaped piston-type extruding member toward said opening to extrude the viscous material from said collapsible pouch;
- and
- said collapsible pouch being formed from a pair of films sealed together to define a hollow internal chamber for holding the viscous material;
- said collapsible pouch including a cross seal having an outlet spout formed therein that is registrable with said opening in said cylinder-type housing means;
- and
- said collapsible pouch being adapted to assume the substantially elliptical shape of said cylinder-type housing means when held therewithin and engageable by said substantially elliptically shaped piston-type extruding member.
A dispenser system including a collapsible, sanitary dispenser pouch formed from thin films of sheet material for holding a substantially large amount of viscous food product for dispensing from a dispenser, comprising in combination:
- said dispenser pouch being formed from a pair of substantially rectangular heat sealable films having two ends and two sides and being 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;
- 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 substantially large amount of viscous food product therein;
- said specifically formed sealed outlet spout portion including sloped internal walls and an outlet tip and being centrally disposed between said substantially straight side seals;
- said sloped internal walls of said specifically formed sealed outlet spout portion forming a single interior surface which slopes toward said outlet tip to form a funnel-shaped interior area to control the flow of viscous product held in the said hollow internal chamber through said specifically formed sealed outlet spout portion;
- said top cross seal including sealed portions formed between said pair of substantially rectangular heat sealable films adjacent to and angularly disposed between said sloped internal wall portions of said specifically formed sealed outlet spout portion and said substantially straight side seals to form angled internal walls in said hollow internal chamber;
- and
- a tear-off strip formed in said other of said two ends, away from said hollow internal chamber, 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, whereby, when said tear-off strip is removed by a user, said outlet tip will be removed to form an outlet opening through which controlled dispensing by an hand-held dispenser of said viscous food product from said hollow internal chamber via said angled internal walls will occur, so as to enable said viscous food product held in said hollow internal chamber to be substantially completely dispensed through said outlet opening formed by the removed outlet tip.
