Abstract (en)
[origin: EP0078761A2] The invention concerns a sealed container comprising two layers of thermoplastic film heat sealed together, a vee-shaped area being formed as part of the heatseal pattern, with the apex of the vee (15) directed toward the interior of the container. When pressure is applied to the container, such as by squeezing it, the heatseal ruptures, beginning at the apex of the vee (15), and continuing through the heatseal in a well defined path. As a result, the contents of the container, such as an individual serving of ketchup, can be dispensed from the container in a controlled manner.
