대표청구항 ▼

A sealed vacuum container system comprising; a) a cylindrically shaded can body; b) a cap unit on said can body, and comprising; i) a sealing cap body having a central upper recess, a central through hole in said upper recess, a plurality of air holes spaced around said central through hole, a first downwardly projecting annular wall engaging a bottom cap, a projecting outer circumferential curved edge, a second annular downwardly projecting wall extending from said curved edge, a third annular downwardly projecting wall, an annular groove formed between said second and third annular walls to accommodate an annular gasket therein; ii) a bottom cap engaged with said first downwardly projecting annular wall, and having therein a plurality of air holes; iii) an annular gasket located in said annular groove of said sealing cap body; iv) an air valve provided in the recess of said sealing cap body, normally closing said plurality of air holes, and having a mushroom-shaped projection extending therefrom to pass through said central hole of said recess of said sealing cap body to thereby keep said air valve in place, and two sloping-up projections for opening said air valve; and, v) a small upper cap covering said air valve, having a circumferential sloping-down surface and two opposite slots to allow said two sloping-up projections to protrude therethrough; and, c) a vacuum pump for pumping air out of said can body, and comprising; i) a stationary cylinder having a central passageway, a stop annular edge and a flange around a bottom having an annular groove inside the flange to engage an annular projection of a pull cylinder; ii) a pull cylinder slidably fitting in said central passageway of said stationary cylinder, and having an annular projection on an upper portion, an air exit below said annular projection, an annular groove in a lower end portion, two opposite air holes in said annular groove, and an annular gasket engaging said annular groove; and, iii) a handle having a cylindrical portion with two lateral curved portions fixed firmly on a top of said pull cylinder above the stationary cylinder to pull said pull cylinder for pumping out the air in said can body; wherein said vacuum pump is placed on said cap unit and said pull cylinder is pulled up and down in said stationary cylinder to draw out the air from said can body, forming a vacuum so that internal and atmospheric pressure difference causes said air valve of the cap unit to tightly close said air holes such that food therein can be preserved for a long period of time.
