Food preservative container

A food preservative container (1) comprising a container body (2), and a closure member (3) fitted over the container body (2) so as to close an opening (2a) of the container body (2), the closure member (3) having an upper portion fitted with a finger grip portion (16), and a peripheral edge (3a) capable of being hermetically and removably fitted to the container body (2), wherein:

• the finger grip portion (16) fitted to the closure member (3) comprises a finger grip main body (33) attached to the closure member (3), a grip outer cover portion (38) circumscribing the finger grip main body (33) and having an upper part joined with the finger grip main body (33) and a lower part annularly extending so as to hermetically contact the closure member (3), and a vent hole (26) defined in an inside region of the closure member (3) circumscribed by the grip outer cover portion (38) for allowing communication between the inside and outside of the closure member (3);
• and the grip outer cover portion (38) of the finger grip portion (16) is formed from a flexible and elastic material such that when the grip outer cover portion (38) is gripped with fingers in order to lift up the closure member (3), the lower part (40) of the grip outer cover portion (38) is partially moved toward a center of the finger grip portion (16) and detaches from the closure member (3) to release a hermetic state of the closure member (3) against outside air thereby allowing an internal space (11) of the container to communicate with the outside through the vent hole (26).
