ABSTRACT:
Containers, in particular plastic bags, for limited doses of liquid, oil, cream doses, and the like, that can be easily opened and reclosed, and that are well sealed and resistant to from tearing and leakage. The container body (envelope) is formed of a thermosealable, substantially flexible composite film (laminated or coextruded). A substantially rigid insert is welded to the inside top portion of the envelope. The insert has a base, a neck with a central hole, a groove fracture part, and a knurled cap from the center of which a pin protrudes. After the insert is fractured and removed, it can be easily flipped over and reinserted in the base to reseal the envelope.
