JAR, CLOSURE Filed Mafch 24, 1930 M n M Patented Sept. 15, 1931 UNITED STATES PATENT OFFICE LINDSAY THORNE ORABBE, OF CHICAGO, ILLINOIS, ASSIGNOR TO PHOENIX-HERMETIC COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF NEW YORK JAR CLOSURE Application filed March 24, 1930. Serial No. 438,540.
The invention relates to new and useful improvements in jar closures, and more particularly to a jar closure which includes a cap secured to the jar by a sealing band which 5 overlies the cap and is adapted to be turned underneath the ledge on a jar.
An object of the invention is to provide a closure structure whereby a uniform pressure may be applied both to the cap and the verlying portion of the sealing band in the region directly above the lip of the ar for holding said cap in sealing engagement with the jar while the band is being crimped underneath the holding lip on the ar.
A further object of the invention is to provide the cap with a recess formed in the outer surface thereof adjacent the periphery whereby the overlying portion of the band will be housed therein with the outer face of the 0 overlying portion substantially flush with the outer face of the cap.
A still further object of the invention is to provide a closure for jars wherein the cap is formed with an inwardly projecting annular bead disposed adjacent the inner wall of the jar on which the cap is to be used whereby a channel is formed in the cap for confining the sealing material to the region directly above the lip of the jar with which sealing contact is made. at
These and other objects will in part be obvious and will in part be hereinafter more fully disclosed.
In the drawings Figure 1 is a view showing partly in side elevation and partly in section a ar closure embodying the improvements applied to a 3 Fig. 2 is a view in section showing a cap or cover for a jar having the improvements applied thereto.
Fig. 3 is a sectional view through a closure showing the same applied to a jar and with the chuck brought into engagement therewith for seating the cover preparatory to the securing of the same to the jar.
Fig. 4 is a view similar to Fig. 2, but showing the closure fully seated, sealed and joined to the jar.
The invention is directed to a closure for jars, bottles or the like, and more particularly to a jar closure which includes a cap or cover portion secured to the jar by a sealing band. The sealing band is provided with a laterally projecting flange adapted to overlie the cap and the lower edge of the band is turned underneath a holding ledge on the jar. Thus it is that the cap is secured to the ar and the jar closed. This is an ordinary form of jar closure.
The invention is directed particularly to the construction of the cap. The cap is provided with a recess in its outer face at the periphery of the cap which is so proportioned as to provide a housing for the overlying flange portion of the sealing band so that the outer face of the flange portion is substantially flush with the outer face of the cap. The cap is also provided with an annular bead disposed adjacent the inner edge of the lip of the ordinary jar so as to produce in the cap a channel for the confining of the sealing material so that the sealing material willbe disposed substantially above the lipof the jar with which sealing engagement is to be made.
Referring more in detail to the drawings, the invention is shown as applied to a jar which is indicated at 1 in the drawings. The jar has a sealing lip against which the sealing materialis pressed and a holding ledge 2 underneath which the band is turned for securing the cap or cover to the ar. The cap is indicated at 4 in the drawings. The cap is made of thin sheet metal. The cap has the usual depending flange 5 at its periphery. The cap also is formed with an annular depression 6 in its outer face which is of a depth substantially equal to the thickness of the metal constituting the holding band. The holding band is indicated at 7 in the drawings. Said band has the usual overlying flange 8 which engages the cap for drawing the cap into sealing contact with the jar. This overlying flange 8 is housed in the recess 6 and the inner edge of the overlying flange is in a measure concealed by the shoulder 9 of the cap. This forming the overlying flange the :chuckwhioh is illustrated at 9 in the drawingswill make contact with the outer face of the overlying-- portion: of theband and. also with the outer face of the cap, asclearly shown in Figs-3 and 4.
The cap 4 is also provided With an annular r bead 10. This annular bead is disposed back a slight distance from the-periphery of: the
cap so that the outer curved ,Wall 11 of the bead forms with the depending flange 5 of the cap a channel 12 for-the sealingmaterial which is indicated-at13 in the drawings.
The sealingmaterial is applied to the cap in-a fluid or plastic form While the capis inverted with the channel facing upward. These inner and outer-Walls of the channel confine the sealing-material so thatit forms a relatively thick sealing gasket which is dis posed so as to make contact with, the outer sealing-surface of the lip of'the jar. The outer face ofthe central portion of the cap 4 is substantially flush with the outer face of:
the portionof the cap directlyover the channel so that when the chuck moves down against the-cap-, it engages the cap firmly not" only in the central portion but directly above the sea-ling material, and it alsoengages the overlying flange of the sealingband and thus it "is that the entire closure 'may be pressed against thelip and the-lip firmly embedded in the sealing material and a-tight' seal held wl1ilethe lo'weredgeof the closure band is spununderneath the holding li'p2 as indicated at 14 in the drawings. 7
In Fig. 8 the cap is shown as loosely ap plied? to the and the chuck asmoved down into engagement with the cap :ready to. force-it into-sealingcontact Withi the jar." In=Fig4 the cap has been-forced down into sealing contact With the jar and the lip of the ar embedded in the sealing gasket and the lower edge of the band has. been spun underneath the-holding; ledge on the ar, and thus the closure secured 'to the 'jar; The band used for securing, the cap to the jar is preferably of the breakable type and is provided 'With a lifting tongue 15 and a holding lug 16. This means for joining the ends? of theband may beof any desired con.- struction.
WVhile' the cap-with the improved features thereof 'i's shownas used in conjunction with a sealingband, it will becunderstood that othertypesofholding means may be provided.
Having fully described my' invention, what I claim as new and desire to secure by Letters Patent,&is:-
1. A closure for jars or the like comprising a yieldable disc-likecap having a depending flange and a channel for retaining a plastic sealing gasket therein, said cap having a recess for receiving and housing an overlying flange of a sealing band for binding thecap to the ar and 'sealing the same.
2. A closure for jars or'the like comprising-a-yieldable disc-like cap having a depending flange. and aMdependi-ng annular bead spaced from-the ,fla'nge and forming a channel for retaining a plastic sealing gasket-therein, said cap having a recess for receiving and housing an overlying flange of a. scalingsband for: binding the cap to the jar and sealing the same.
3. A'- closure for-jars or-the like comprising a 'yielda-ble disc-like cap, having ;a depending flange .anda chanel. for retaining a" plastic sealing gasket therein, a sealing band for binding the 'cappto the jar, said band havinga flange overlying the cap-and said cap having a recess'for'rece-iving and housing the overlying-flange ofqthe band with the outer, face of'the flange substantially flush with the. outer --face ;of 'the' cap;
4h A closure'for jars or thelike comprise 7 ing a yieldable disc-like --ca*p: having :a depending flange anda depending annular bead spaced from the flange and'forminga channel forretainingga plastic sealing gas kct therein, a sealing band' for binding the cap to the jar, said band having a flange overlying the cap and 'saidcap having-a re cess for receiving and housing said overlying flange with the outer' face of the flange substantially flush with the outer face of the cap.
In testimony whereof, Iafli'X'my signa-' ture.
