DISPENSING PACKAGE |
摘要 |
A package for carrying and dispensing contents through at least one metered opening includes a plastic backing having a first elastic limit and a shear modulus sufficient to maintain the package in a substantially flat configuration; a first score extending at least partially into the first side of the plastic backing; a coating formed on a second side of the plastic backing having a second elastic limit that is greater than the first elastic limit; a pouch formed on the second side of the plastic backing that is adapted to carry the contents of the package. Flexure of the plastic backing by a first amount is sufficient to cause the plastic backing to exceed the first elastic limit and break along the first score while flexure to a folded position is insufficient to cause the coating to exceed the second elastic limit.
