SEALING RING Filed Nov. 19, 1946 Inventor fi efly 1'); y La eryre Patented July 27, 1948 UNITED STATES PATENT OFFICE SEALING RING Henm'ng Lagergren, Montgomery, N. Y. Application November 19, 1946, Serial No. 710,846

This invention relates to new and useful improvements and structural refinements in sealing rings, more specifically, rings such as are commonly employed in association with so called Mason jars, and the principal object of the invention is to provide a ring of the character here in described which may be easily and conveniently removed from its position under the sealing cap, after the jar has been sealed.

A further object of the invention is to provide a sealing ring which is simple in construction and which will readily lend itself to economical manufacture.

Another object of the invention is to provide a sealing ring which is otherwise well adapted for the purpose for which it is intended.

With the above more important objects in view, and such other objects as may become apparent as this specification proceeds, the invention consists essentially of the arrangement and construction of parts as illustrated in the ac companylng drawings, in which:

Figure 1 is a plan view of the invention.

Figure 2 is an edge view thereof.

Figure 3 is a perspective view showing the manner in which the ring is removed from the jar, and

Figure 4 is a cross sectional view, taken substantially in the plane of the line 4-4 in Figure 3.

Like characters of reference are used to designate like parts in the specification and throughout the several views,

Referring now to the accompanying drawings in detail, the invention consists of a sealing ring designated generally by the reference character ID, the same consisting of an annular gasket H, preferably formed of rubber, and provided with an integral, outwardly projecting tongue l2.

The lateral edges of the tongue l2 are arcuated in a mutual, outwardly divergent relation, and are notched to provide a series of teeth l3.

When the invention is placed in use, the gasket is, of course, positioned upon the Mason jar 1 Claim. (Cl. 288-20) l4 under the conventional sealing cap I5, in the well known manner.

When it is subsequently desired to open the jar, the tongue I2 is gripped between the thumb and the forefinger, so that the tongue is doubled upon itself, as is best shown in Figure 4. At the same time, the fingers will engage the teeth l3 and it will be found that in this manner, the tongue will be firmly and securely gripped by the fingers and that the gasket ll may be easily removed from the jar.

It is believed that the advantages and use of the invention will be clearly understood from the foregoing disclosure and accordingly, further description thereof at this point is considered unnecessary. 1 1

While in the foregoing there has been shown and described the preferred embodiment of this invention it is to be understood that minor changes in the details of construction, combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as claimed.

What I claim as my invention is:

A sealing ring for jars, comprising an annular gasket formed from resilient material, and an outwardly projecting tongue formed integrally at the outer edge of said gasket, said tongue having outwardly divergent lateral edges formed with sets of teeth, and being bendable to a longitudinally doubled position wherein the sets of teeth on said edges are disposed in adjacent arouate rows.

HENNING LAGERGREN.
