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.

A reclosable envelope container, comprising: (a) a body formed of two thermosealable, substantially flexible composite films, said films having edges heat sealed together, said body having a bottom, two sides and a top; and (b) a substantially rigid insert heat sealed between said two films along the top of said body at a location substantially central to and spaced from the two sides of said body, said insert comprising: (i) a base having a longitudinal axis parallel to the top of said body, a central bulge extending laterally with respect to said longitudinal axis of the base and an aperture extending centrally through said central bulge in a direction perpendicular to said longitudinal axis of the base and parallel to said two sides of said body; (ii) a neck extending upward from said base in said perpendicular direction, said neck having a central aperture aligned with the aperture of said base; (iii) a portion of reduced diameter above said neck adapted to fracture upon the application of torsional force; and (iv) a hollow cap having a knurled outer surface and a pin which extends centrally upward within the hollow of said cap, said pin having a length substantially equal to a height of said neck and being of a diameter so as to snugly fit within the aperture of said base and seal said envelope after said portion of reduced diameter has been fractured and said cap has been removed, flipped over 180°, and placed back over said neck.
