JAR-CLOSURE.
Speccaton of Letters Patent.
Patented Dec. 20, 1910.
Application led February l, 1910. Serial No. 541,230.
To all whom it may concern:
Be. it known that l, FRANCIS J. ltlAoruN, a citizen ct the United States, residing at the city and county ot' San Francisco and State ot lCalifornia, have invented new and useful improvements in Jar-Closures, of which the following is a specification.
lily intention relates to jars or containers which are designed to contain hermetically sealed goods.
lt consists in a combination of parts and details ot' construction which will be more tally explained by reference to the accompanying drawings, in which- Figure l is a view of a container and a cap. Fig. 2 is an enlarged sectional view, showing the formation of the jar top and joint. Fig. is a moditication of the same.
ln the manufacture of what are known as vacuum l or containers for the purpose ot' containing hermetically sealed goods, an ii'isurmountable ditliculty in making tight joints has been the fact that when the glass cools the outside edge or periphery will, by reason or' the shrinkage, become full of little cracks. or what are technically known as crizzles and these arc sufcient to allow air to enter, and to break the vacuum produced by means or a hermetically sealed cover secured upon such a container. he very large percentage of containers that are thus affected, has made it almost impossible to practically employ this class of closures.
ln my invention l form the container1 A with an outer lip 2, and an inner lip 3, with a groove. or depression 4 between the two. The outer lip may be subject to the cracks or crizzlcs before described, by reason ot' thc shrinkage oi the glass, when that material is used, and the tension thereon; but the inner lip 3, by reason orn the compression ot' the glass.r will not be thus cracked or broken. and it is this inner lip that l depend upon, in conjunction with my cap, to torni a joint. The cap consists ot a central body portion 5, and may either have a plane surface G adapted to rest upon the upper edges of the lips 2 and 3, or it may form an annular channel made in it by means ot a down-turned outer rim or flange 7. The proportions oic this cap to the jar may be such that the surface 6 lits over the inner lip f3 ont the jar, and the flanged portion 7 registers with the groove or channel 4L between the inn xi' and outer lips 2 and 3.
yIn order to form a joint l may fit a sealk ing band 8 into the groove or channel L in the rim. This band is made of any suitable material which will form a joint with the lip 3, and being compressed or tted into the groove 4L, it is readily maintained in position7 and the caps thus prepared are in readiness for use. vWhen the cap is placed upon the container7 this gasket S will rest upon the inner lip 3 of the container, the rim or flange 7 registering with the groove or channel at, and lying within the outer lip 2. The important point in this construction is that the inner lip 3, by reason of the compression of the material of which the container is formed, by contraction on cooling, is never aected by cracks or crizzles, and upon this lip the sealing is effected. The outer lip, which is here shown projecting slightly above the inner lip is, on the contrary, subject to these cracks by reason of the tension caused by contraction and cooling, but in my sealing there in no occasion to use this outer lip. I am consequently enabled to make a very high percentage of jars that can be used for my purposes, and can disregard any cracks or openings which naturally form in the outer lip of all glass containers, since my joint and sealing are made upon the inner and perfect lip.
Instead of forming the cover with a downturned flange as shown at 7, I may continue the surface 6 outwardly at such a bevel and with such increased diameter that it will extend substantially over the outer as well as the inner lip of the jar. lVith this construction, the sealing band 8 is of such width and flexibility that it extends over both jar lips so that when a vacuum is produced within the jar, it is also formed in the channel between the lips 2 and 3; and the band 8 will be forced into the channel, and thus form a much larger sealing surface of contact.
Having thus described my invention, what I claim and desire to secure by Letters Patent isl. A container having concentric inner and outer lips spaced from each other to form an intermediate groove or channel,
said inner lin being of less height than the outer lip; a cap or cover, and a gasket resting upon the inner lip and'in the groove or channel between the saine and the outer lip and having its edges lying within the outer and receive the outer lip of the cover; :ind u gasket extending over the inner lip of the container and into the groove of Said oontainer and having its outer edge lying Withiip, said inner` lip und the portion of the i gasket thereover forming the heiinetic joint between the container and cap or Cover. i A glass container having concentric in- 1 ner and outer lips spaced from each other to in the outer lip of the container. forni :in intermediate groove, said inner lip 1n testimony whereof have hereunto being or' less height than the outer lip; a set iny hand in the presence of tivo subcap or cover having concentric downwardly i soribing Witnessee. projecting concentric ribs and an inter1neg FRANCIS J. MCKIN. diete groove, said groove adapted to receive the inner lip of the container and the groove 1 in the container adapted to register With Witnesses GEO. H. STRONG, JAS. W. Dor-remy.
