A package comprising a cylindrical plastic tube closed at each end by an ultrasonic band seal. The seal at one end has a sealed region which is narrower than any portion of the other seal whereby squeezing of the package produces an immediate one-shot dispensing of liquid contained therein by causing rupture of the narrow region of the seal. Various package forms include perpendicularly arranged bands to provide a tetrahedral shape, a tab extending beyond one seal to provide identification of the contents of the package, notched seals providing a tear open package, and a multiple package construction in which one fluid containing tube is contained within another.

This application is a divisional of our pending patent application Ser. No. 720,084, filed Sept. 2, 1976, now abandoned.
A multiple-compartment container is formed from an elongated sleeve of flexible material. Opposing end portions of the sleeve are respectively sealed together. A third seal of the walls of the sleeve, at a location spaced between those end portions, defines first and second hollow compartments respectively on each side of that third seal. The third seal is effected by a twisting of the sleeve about its longitudinal axis. There is illustrated a still further and preferred fourth seal at a location spaced between the third seal and one of the end portions so as to define a still further hollow compartment, and that additional seal also is effected by a twisting of the sleeve.
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.
A detergent-containing water-insoluble closed bag is so constructed as to open and discharge its contents under mechanical action in a washing machine in use. The seams of the bag may be heat-sealed or cold pressure sealed such that at least one seam will burst open in use. The bag material may be porous with a pore size selected to minimize dusting of the detergent. The bag material may include a thermoplastic component to enable heat-sealing. The bag may contain conventional detergent compositions and/or other fabric treatment materials. These products give consumer benefits both by way of improved efficiency in the use of the detergent compositions and in greater convenience in use.
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.
An easy-open beverage container which can be selectably reclosed and reopened, after the container initially is opened. The reclosure structure may be contained on an opening tab, or alternatively may be separate from the tab.
