ABSTRACT:
A package for shipping, storing and controlled dispensing of a unit or single use quantity of liquid comprises a pair of flexible, liquid-impermeable sheets superposed one over the other. Each of the sheets comprises a first substantially rectangular section and a second substantially rectangular section, having different widths, and a transition section interconnecting the other two sections. One of the sheets has a recess formed therein which defines a pocket receivable of a unit or single use quantity of liquid. The other sheet defines a cover extending across and covering the recess. The recess also includes a portion defining an elongated and narrow spout extending outwardly of the pocket. The sheets are hermetically sealed to one another about their periphery completely about the recess. The "seal" may be manually peeled back in the region of the spout to open the package. The portions which peel back and the portions of the package proximate the opening are shaped so as to arcuately taper back from the opening, thereby eliminating any sharp edges in the vicinity of the opening. The package is particularly suitable for use with "eye drops".
