AT NEY Patented Aug. 22, 1940 e UNITED STATES VACUUM JAR CAP SEAL' Royal W. Wynings, Youngstown, Ohio; Etta Wynings, guardian of,4 said Royal W. Wynin competent, assignor, by direct and mesne assignments, to Elsie Keefer, Youngstown, Ohio y Application September 15, 1938, Serial No. 230,124
- 9 Claims. (01.-215-37) This invention relates to a vacuum jar-cap seal and it consists in the constructions, arrangements and combinations herein described and claimed.
It is an object of the invention to provide a jar cap in which a vacuous channel is formed cooperative with the mouth of. a jar for effecting a hermetic seal.
It is also an object of the invention to provide a closure which may be quickly applied to a jar without employment of special tools for manipulating the closure proper, as has been required heretofore, and similarly the closure may be readily removed upon breaking of the suction seal, and this without damage to the closure so that it may be used repeatedly.
It is also an object of the invention to provide means for effectively centering the closure upon a jar.
Additional objects, advantages and features of invention will be apparent from the following description considered in conjunction with the accompanying drawing, wherein Figure 1 is a fragmentary sectional view of a jar having a closure applied.
Figure 2 is a similar v iew 'of a modified form of jar. p
Figure 3 is a plan view of the closure.
Figures 4 to 6 illustrate cross-sectional views of modified forms of suction channels.
There is illustrated a jar I0 having a mouth II, the rim I2 of which is quite wide and has a smooth upper formation for a purpose presently to be explained.
The closure for the jar is indicated at I3, which as shown, is formed from rubber as an annular disk and comprises a top portion I4, a circumscribing edge I5, the lower edge of which is molded or otherwise shaped into a continuous circumscribing channel I6.
An annular iiexible metal disk I1 is freely mounted in an annular kerf iI' formed inthe cap, immediately below the top portion I4, the `disk being of a diameter terminating on a line approximately through the vertical center of the channel I6.
It should be understood that the channel I6 l is of lesserwidth than the rim I2 so that the channel I6 may spread laterally on the rim for effecting a vacuous state between the channel and the rim, and this without permitting the outer edges of the channel from projecting beyond the peripheral edge of the rim. Obviously, if the edge of the channel were permitted to overlap the rim only slightly, an effective seal could not tbe obtained.
While I have shown the circumscribing edge I5 of substantial height, this is not essential, for it has been found in actual practice that the edge I 5 may be of slight height, as shown in Figure 2, the suction action created by the channel upon compression thereof against the rim being ample to seal the cap to' the jar. Also, in Figure 2 the neck I8 of the jar is shown as having an outwardly projecting flat flange I9, the outer edge of which is provided with an upstanding rim 20 of slight-height. Thus, the flange I9 affords an ample surface for reception of the channel I6, and the rim serves to center or guide placement of the' closure cap thereupon, assuring proper sealing of the cap.
Obviously, the channel I6 may have various cross sectional contours, and in vFigure 4, the
-channel I 6a is illustrated of angular formation.
In Figure 5, the channel |61) is shown as semicircular, while in Figure 6, 'the channel Isc is of V-shape.
In use, after the jar has been filled with the contents, the closure cap I3 is presented to the rim I2 or flange I9, as the case may be, with the channel I6 centered thereon, and downward pressure exerted to the cap so as to compress the channel I6 toY displace air therefrom. When pressure is released, the channel I6 ter'ids to assume normal position, the edges of which firmly grip the rim or ange, effecting a hermetic seal between the rim or flange and the channel.
It has been found in actual practice that a downward slap directly upon the cap effects securement of the cap, and such a blow also causes a flexing of the disk Il as indicated by dotted lines in Figure 1, thereby exerting an vtration only, and I consider as my own all such modifications as fairly fall within the,scope of the appended claims.
I claim:
1. In combination, a. receptacle having a fiat rim mouth, a cap, said cap having a suction channel upon the underside complemental to the rim, and said channel being compressible to effeet hermetic seal with the rim of the mouth.
2. In combination, a receptacle having a fiat rim mouth, a rubber cap therefor, said cap hav-v ing a circumscribing suction channel complemental to the rim, and a metallic disk carried by the cap, one face thereof being exposed to the interior of the receptacle when secured thereupon, the peripheral edges of the disk terminating on a line approximately medially of the channel.
3. In combination, a receptacle having a fiat rim mouth, an upstanding rim circumscribing the mouth, a rubber cap therefor, said cap having a circumscribing suction channel complemental to the rim, and a metallic flexible disk carried by the cap, one face thereof being exposed to the interior of the receptacle, when secured thereupon, the peripheral edges of the disk terminating on a line approximately medially of the channel.
4. A suction closure cap comprising a disklike body of rubber having a circumscribing suction channel, an annular kerf formed in the body, said kerf terminating on a line approximately medially of the suction channel, and a exible disk seated within the kerf.
5. In combination, a receptacle having a flat rim mouth, a cap therefor, and said cap having a suction channel complemental to the rim, the
channel normally having a, width less than the width of the ilat rim mouth.
6. In combination, a receptacle having a fiat rim mouth, a flexible cap, said cap having a suction channel complemental to the rim, said suction channel normally having a width less than the width of the at rim mouth, and a metallic disk carried within the cap, said disk being of a size extending over the major medial portion of the cap. 2
7. A suction closure cap comprising a body of rubber or the like having a circumscribing suction channel upon the underside thereof and a disk Within the body, the peripheral edges of the disk terminating on a line approximately medially of the channel.
8. A suction closure cap comprising a body member of rubber having a circumscribing suction channel upon its under side, a kerf formed .in the body over the suction channel, and a disk seated within the kerf.
9. In combination, a, receptacle having a rim mouth, a cap therefor, said cap having a circumscribing suction channel complemental to the rim, and said channel being compressible to effect a hermetic seal with the rim.
