Definitions

• Another object of my invention is to provide a device of this Character whereby a positive seal may be eifected.
• Another object is to provide a device of this character wherein the seal maybe readily broken when it is desired to open the container to which the sealing means is' attached.
• Another object is to provide a device of this character having means for looking the seal.
• a still further object is to provide a device of this Character of simple and durable construction and of lowmanufacturing cost.
• Figure 1 is a Vertical sectional view through the sealing means attached to the top of a glass jar with the valve-like stopper loosely received in the opening of the cover so that air may be exhausted from the jar.
• Figure 3 is a plan view 'of the device.
• Figure 4 is a side elevational view of the stopper. i
• Figure 5 is an end elevational view of the same.
• Figure 6 is an under plan view of the stopper.
• reference numeral l indicates a jar, the top portion onlyof which is shown.
• the upper end of the jar is threaded and a metal cover is screwed thereon.
• the cover is screwed lightly onto the top of the jar.
• Two annular seals of rubber or other suitable material are provided, numbered
• the cover I i is shown screwed tightly onto the jar in Figure 2 wherein the seals
• the cover ll is provided with a central opening having a downwardly and inwardly inclined fiange 14. Within the opening there is a stopper IS of rubber or other suitable material, the sides of said stopper tapering downwardly and inwardly at substantially the same angle as the fiange H of the cover. The lower end of the stopper is provided with outwardly or laterally extending arms IB to limit the outward or upward movement thereof and spaced upwardly of said arms there is an annular shoulder ll on the stopper.
• Any suitable vacuum pump means may be em- I -I4 so that the stopper may freely rise and fall to act as a valve, the shoulder seating on the inner surface of the flange to prevent air returning into the jar. After the air is exhausted from the jar the stopper is pressed inwardly or downwardly until the shoulder l'l thereof is below the lower end of the flange which it engages to form a secure seal as shown in Figure 2.
• a oontainer a cover secured thereon and having an opening therein, a downwardly and inwardly inclined flange about the opening, a tapered stopper adapted to be operativeiy received in the flanged opening, outwardly extending arms on said stopper adiacent the inner end thereof, and a shoulder about the stopper in upwardly spaced relation to said arms, said shoulder being above the lower edge of the fiange during exhaustion of air from the container and adapted to be forced below said lower edge in seaiing and looking association therewith after the air has been exhausted from said container.
• a device of the class described the combination of a container having a cover secured thereon, said cover having a flanged opening therein, the flange extending in a downwardiy and inward taper, a tapered stopper adapted to be operably received in the flanged opening, means for normally limiting the upward movement of the stopper, and means for seallngly engaging the inner edge of the fiange of the cover opening when the stopper is pressed inwardly in said opening, said means being normaliy above the inner edge of the fiange during evacuation of air from the container.
• a vacuum container having an opening therein tapering inwardiy from the outer side of said container, a tapered stopper operably received in said opening, laterally extending means on the inner end of the stopper adapted to limit the outward movement of said stopper, and means on said stopper adapted for sealing engagement with the inner edge of the opening when said stopper is fully pressed into said opening, said last mentloned means being normally outside said inner edge of said opening.
