against rotation while the outer or metal.
cover is being screwed down upon the rub ber washer used between the top edge of the bottle neck and the under side of the porcelain lid. A further means is provided for enabling the metal cover to exert a direct and localized pressure on the rim portion of the porcelain lid, thereby exerting a direct contact pressure on the rubber washer and forming a much better rubber closed joint than is usual in the case of the commonlyV used jars.
Another feature of the device is the provision of a combination pressure, and molten fluid seal, in other words a double seal jar closure having the means above described for obtaining a perfect pressure tight seal between the porcelain lid used and the top edge of the bottle neck. The above features will be more fully explained as the description proceeds herein. o
In the accompanying drawings forming art of this specification, I have shown o ne orm of the physical embodiment of my in.- vention constructed according to the best mode I have lso far devised for the practical application of the principles of my invention.
Figure l is a vvertical section taken A through a jar showing my type of closure in position thereon. Q
Figure 2 is a top plan view of same having g non-frictional washer such as paraiiined a portion cut away for purposes of illustra' paper of substantial thickness and of shape shown in Figure 4.
Numeral 5 indicates a bottle or jar having a raised annular shoulder 6 forming a groove 7 around the top Iof the jar. The metal vcover 1 is provided with a thread 8 in the ordinary .way and adapted to be screwed on the complementary threads on the neck of the bottle or jar 5 in the usual fashion. 9, 9 indicate a plurality of bosses,
preferably only two being required, formed in the bottle neck 10, and complementary recesses 11, 11, are made in the porcelain lid 2 for a purpose next described. It is seen that by having the porcelain lid 2 held stationary on the top of the bottle neck 10, by means of the inwardly standing bosses and recesses, 9, 9 and 11, 11, respectively, and also having a paratline or frictionless washer 4 on the top of the porcelain lid 2, that when the metal cover 1 is screwed down on thc bottle neck threads 15, that the metal cover readily slides in a rotary direction over the top of the lid 2and in this way a much greater grip can be obtained by the cover threads 8 on the bottle neck 10. The reason being that when the cover l is screwed around on top of the rubber washer 3 in the case of an ordinary lid the rubber washer exerts an adhering resistance to the advancement of the cover while with my invention the rubber washer does not advance ifi a rotary direction at all, only the cover 'i being advanced and only against a frictionless paratiine washer 4 as is readily appreciated. In this way an exceedingly tight grip is obtained by the cover 1 against the rubber washer 3 makin a practically yair and fluid-tight seal against the passage of fiuids from within the jar. It is also observed in this connection that as the porcelain lidl is unattached to the metal lid 1 in any way that the former can be readily removed and cleaned, thus being much more sanitary than when the porcelain is attached to the metal lid in the customary way, many lids being now thrown away on account ot' ,the fluid contents of the jars getting iii between the porcelain and the surface of the metal lid, and having no means of being cleaned such lids are not used again.
It is noted that in some cases the arrangement of parts may be used without the bosses 9, and recesses 11, but the use of these parts are considered almost essential to the perfect working of the device. The lid 2 is lightened somewhat by the cut-away portion 14 being removed as shown. The use of the paraffine washer 4 enables the pressure exerted by the cover 1 to be directly transferred to the rim 16 of lid 2 thus directing `the pressure directly where it is needed to depress the rubber washer 3 against the top edge 12 of the bottle neck 10 and thus obtain a good effective joint between the under side of thelid rim 16 and the said edge 12 of the jar neck just mentioned.
As a second seal after the cover 1 has been screwed down with a good tight joint just described, a further air-tight seal is provided by means of pouring molten paraine, or similar viscid fluid in the groove 7 so as to completely submerge the lower edge of the cover 1, and for this purpose it is evident that the top ofthe shoulder or rim 6 must be of sufficient height to be above thebottom edge 17 of the cover l, so that when the fluid parafine is poured into the groove 7 the bottom of the cover will be submerged by said Huid. From which description it is seen that when both the pressure seal by means of the frictionless cover 1 and rubber washer 3, and the molten-fluid seal at 18 is used that the jar is perfectly air and iuid tight, and same lhas proven in actual use to bevery efficient from a practical standpoint, as can be readily proven by inverting the jar full of preserves into water, when if there is any leakage a sizzling sound, with escape of air 'P shows instantly in the waterjin which the end of the jar is submerged. With my type of jar it has been shown in test of this kind to be perfectly air and fluid tight.
Another feature of interest with reference to the contact of the preserve content ofthe jar and metal is that when the ordinary Mason jar is inverted that the preserves follow along the thread grooves of the cover Islient washer on the top edge of the jar neck, a jar lid having a number of complementary recesses adapted to engage the said jar neck bosses, superimposed on said washer, an annular non-friction washer on top of said jar lid rim, and a cover having a single downwardly projecting rim engaging.
the threaded jar neck and compressing the rubber washer between the jar lid rim and the top edge of the jar.
2. In a jar closure, a jar having an annu- .lar groove formed around the neck of the jar, a plurality of inwardly projecting bosses formed on the jar neck, a resilient washer positioned on the top edge of the ^neck of the jar, a lid on top of the resilient washer, having complementary recesses engaging the jar bosses, a non-frictional washer on the top of the lid, a cover on the latter washer having a single downwardly projecting rim with means of attachment to the jar neck, and viscous means in the annular jar groove submerging the bottom edge of the cover and providing a second seal for the contents of the jar.
In testimony whereof I aiix my signature. y
