JAR-CLOSURE.

T all whom it may concern:

Be it known that I, THOMAS LUCIEN TALIAFERRO, a citizen of the United States, residing at Chicago, in the county of Cook, State of Illinois, have invented certain new and useful Improvements in J ar-Qlosures, of which the following is a description, reference being had to the accompanying drawing, and to the figures of reference marked thereon.

. The invention relates to new and useful improvements in jar closures, and more particularly to the construction of the closure whereby it is firmly held on the jar.

An object of the invention is to provide a jar closure having means, forming part of the closure, which frictionally grips the side wall of a glass jar, or the like, for holding the closure on the jar.

A further object of the invention is to provide a jar closure of the above type, wherein the frictional gripping means is formed at the lower edge of a vertical skirt and resides in an inturned flange set at an angle to the skirt so as to spring and yieldingly grip the side wall of the jar.

In the drawings which show by way of illustration one embodiment of the inventioni 'Figure l is a sectional view through a jar closure embodying my improvements;

Fig. 2 is a similar view showing the closure as applied to a ar;

Fig. 3 is a diagrammatic view showing in dotted lines the jar and the new position of the spring flange.

The invention is particularly directed to a jar closure which may be used for closin jars, such as jelly glasses-orthe like, whic jars are provided with a vertical smooth outer wall. Said closure is preferably formed with a top portion and a vertical depending skirt formed integral therewith. At the lower edge said skirt is turned inwardly and upwardly at an acute an le to the skirt, thus forming a yielding ange. The closure is so proportioned relative to the jar that the inner diameter at the extreme upper edge of the flange is less than the outer diameter of the jar, so that when said closure is crowded on to the jar, this flange will yield, together possibly with some yield ing in the skirt, so as to permit the skirt to slide down along the outer side wall of the jar and the inturned flange will impinge Specification of Letters Patent.

Application filed June 27, 1919. Serial No. 307,056.

against the wall of the ing the closure on the jar.

Referring more in detail to the drawings, I have shown my improved closure as applied to a jar, indicated at 1, which is jar, thus firmly holdformed with an outer straight or vertical wall 2, or a wall which is substantially straight. This is the usual construction of a jelly glass. It is understood, of course, that from certain aspects of the invention, the jar may be of any shape, so long as the jar, at the mouth thereof, has a straight outer vertical wall. The closure consists of a top having a substantially vertical epending skirt 4, extending entirely around the top portion 3 and preferably formed inte ral therewith. At the lower edge said s 'rt portion is provided with an inwardly turned flange 5. This flange is formed by bending the metal of the skirt inwardly and up wardly. This inturned flange serves as a ortion 3, i

reinforcement for the lower edge of the skirt. It serves, also, as the yielding means for holding the closure on the jar. The extreme inner diameter of the flange 5 at the upper part thereof, is slightly less than the exterior diameter of the jar, but the parts are so proportioned that the closure may be crowded down on to the jar. In the crowding of the closure on to the jar, the outer skirt may yield slightly, butthe inturned flange more particularly yields, taking a different angle to the skirt. The extreme inner edge of the flange impinges against the outer wall ofthe jar. The' 1nherent spring of the skirt and the flange firmly presses'this edge against the side wall of the jar and thus frictionally grips the side wall and holds the closure on the jar.

I have illustrated the closure merely as a cover for the jar without securing any sealing effect. It will be understood, of course,

that sealing material may be used with the closure, if desired. The essential feature of the invention consists in this inturned flange set at an angle to the skirt, which is completely housed within the limits of the closure and which firmly grips the outer wall of the jar so as to hold the closure on the jar. It will be noted that the inturned flange is continuous and, therefore, the jar will be gripped by the flange throughout its entire circumferential extent.

It will be obvious that minor changes in the details of construction and the arrangement of parts may be made without departing from the spirit of the invention as set forth in the appended claim.

Having thus described my invention, What I claim as new and desire to secure by Letters Patent, is:

The combination with a glass jar having an outer smooth substantially vertical wall,

0 of a metal closure therefor comprising a top portion,and a substantially Vertical depending skirt connected to said top portion the inner wall of said skirt being spaced irom the outer wall of said glass jar, said skirt 15 flange being slightly less than the exterior diameter of the glass jar, whereby said flange will yieldingly grip the vertical side wall of said glass jar and hold said closure on the jar.

In testimony whereof, I aflix my signature.
