This invention relates to a container with a self-contained evacuation lid. The container is provided for preserving food and is closed on the top by the evacuation lid. The lid includes a piston rod to be reciprorated up and down such that air inside the container is pumped out. An elastic element is fitted under the piston rod to bias a depressed part of the lid upward for an upward stroke when the depressed part is released after the downward movement. A valve rod is pulled to release the vacuum of the container for removal of the lid.

A container with a self-contained evacuation lid, comprising a container body for containing food therein having an annular round top lip, and said evacuation lid; said evacuation lid including a cover bottom, a piston rod, a mediate cover section, a cover top section, an annular connector, and a valve rod; said cover bottom comprising an annular protrusion, an annular vertical section, an annular wall, an operational chamber, and a ventilating channel; said annular connector including an annular retaining groove, and an annular supporting section; said annular retaining groove retaining said annular protrusion of the cover bottom to connect the cover bottom with the annular connector, said annular supporting section resting against said annular round top lip of the container body to form a closure over the container body; said operational chamber being defined by said annular wall; said ventilating channel being arranged next to said annular wall and connected with a socket with a plurality of L-shaped pads disposed in between to form apertures, and having a coned hole formed between the annular wall and the ventilating channel, and a through hole formed on the ventilating channel opposing the coned hole; said mediate cover section being connected with both said cover bottom and said cover top section and having a hollow cylinder in a center thereof; said cover top section including a flexible portion with a truncated top to connect with a depress part having a plurality of holes; said piston rod including a rod portion and a piston head section; said rod portion being passed through said hollow cylinder of the mediate cover section, and connected to said depressed part with apertures formed in between; said piston head section being housed within said operational chamber, connected to an elastic element disposed inside said chamber, and having an annular trench; said annular trench having a plurality of air through holes and being encircled by an airtight ring; said airtight ring tightly blocking up said air through holes of said annular trench in downward movement of said piston rod, and releasing the blockage on said air through holes in upward movement of the piston rod; said valve rod being passed through said coned hole, said through hole of said ventilating channel, and a hole of said mediate cover section, and capable of blocking and ventilating said coned hole and said through hole of said ventilating channel by means of a coned protrusion and a mediate protrusion thereof respectively; said elastic element biasing said piston rod upward after said depresed part is depressed and released; in said depressing motion, said coned protrusion releasing the blockage on said coned hole, and air contained inside said container body flowing to said operational chamber through a path formed by said apertures between said ventilating channel and said socket, said ventilating channel, and said coned hole; in said releasing motion, air within said chamber being forced to flow out through a path formed by said holes of said annular trench of said piston head section, said operational chamber ,said rod portion of said piston rod, said apertures between said rod portion and said depressed part, and said holes of said depressed part.
