JAR-CLOSURE Specification Letters Patent.

Patented Dec. 22, 1908.

To all whom it may concern:

Be it known that I, ALFRED (J. .MoCLos- KEY, a citizen of the United States, residin at Philadelphia, county of Philadelphia, an State of Pennsylvania, have invented a new and useful Improvement in J ar-Closures, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which form a part of this specification.

The object of my invention is to provide a closure for a jar adapted for the reception of preserves, condiments, canned goods and the ike, which will absolutely exclude the ingress of air so as to preserve the contents indefinitely, and which may be readily removed and replaced.

It is also my object to provide a closure having the foregoing characteristics which will be simple in construction and inexpensive to manufacture.

These objects are attained in the closure illustrated in the accompanying drawings, in which Figure 1 is a perspective view of the jar sealed and covered and with fastener a plied to the lid. F i 2 is a vertical sectiona view of the same, Fig 3 is a perspective view of the ,closing cap. Fig. 4 is a perspective view of the asket. Fig. 5 is a perspective view of the astener for the lid.

The inner wall of the jar or is cut away circumferentiall at its to to form an annular ledge or shou der 1). T 1e jar is swelled outwardly near its top to form a projection 0 having a flat upper surface or ledge (1 whose width is increased by reducing the thickness of that part of the jar above the projection.

The cap comprises the base e from the periphery of which projects upwardly the rim f. From the up er edge of the rim projects outwardly the ange 9, having an annular shoulder or led e 7' near its perlpheryf The base 6 is of a s 'ghtly curved form so as to form a concavity in its lower face.

\ center ofthe base is a small orifice h prefercork or rubber.

ably surrounded by a flange on the upper face so as to extend the length of the orifice and ada tit to receive a cork or stopper i preferab y of com ressible material such as is a asket of cork, rubber, or other compressil ale material adapted to surround the rim f and underlie the flange g.

The cap is applied in the following man- In the.

nera The jar is substantially filled with the preserves, which should be highly heated.

Thecap is..

when-introduced into the jar.

then a plied to the jar, the rim f and gasket k exten ing within the jar, and the ca is, pressed down into position. The part 0 the,

gasket below the shoulder b is thus compressed between the 'ar and cap, while theupper-part of the gas et is forced or bulged outwardly by the shoulder 7' so as to partly overlie the shoulder 1'), thus forming a tight joint between the cap and jar. The application of the cap will displace the excess of preserves upwardly and cause it to exude from the orifice h. The stopper '8 is then insertedthe cap, all that is necessary is to insert the blade of a knife or other convenient edged tool between the flange g and the up er edge of the jar. Owing to the bevel of th e rim when once one edge of the cap is slight y raised, the joint is broken and the vacuum relieved, and vei little additional force is required to entire y remove the cap.

After the cap is applied as described, the flanged lid Z is placed on the jar so that the lower edge of its flange rests above the ledge d. To hold the lid in position, there is provided the fastener shown in Figs. 1 and 5, which is com osed of a single plece of wire. This-wire is ent to form a central curved oke m, from each end of which the wire is ent u wardly, as at n, thence horizontally forwar l as at o, and thence downwardly, as at p, t e last named downward bends having their extreme ends bent somewhat backwardl The wire is made of sprin metal, and t e horizontal bends conver c 50111 the yoke toward their free ends. he edge of the lid Z is cut away at r, Fig. 1, so that, when the jar is in use, the lid may be applied to the jar, while the bowl end of a spoon remains therein, the shank or handle of the s oon projectin through the recess 1' in the li To app y the fastener, the free ends of the fastener are forcibly separated and the fastener ap lied to the jar, as shown in Fig. 1, so that the yoke m underlies the projection c,

the bends 0 overlie the lid, the bends n and 7), e'xtend alongside the projection c and the flange of the lid while the extreme ends of the bends extend under the projection 0.

Owing to the elasticity of the wire and the I tendeney of the free ends of the fastener t0 spring together, the lid will be held on the jar by both a dmx'mx'ard pressure and a lateral Y pressure. ends thereof are merely sprung further apart and the fastener slipped otl.

Having now fully described my invention, what I claim and desire to protect by Let-- P teis Patent is:

1. "the combination with a jar whose Wall is narrowed near its upper edge to form an 1 To remove the fastener, the free 1 compressible gasket adapted to surronnd the rim and be confined by the rim and flange against the inner wall of the jar so as to partly overlie said ledge.

2. The combination with a j ar Whose outer wall is out awe y to form an external annular ledge, of a compressible gasket adapted to be confined against the inner wall of the jar, a cztp comprising an oritieed base and an lipwardly and outwardly extending riin adapted to so eontlnesaid gasket, a stopper adapted to close the oriiice in the cap, and a lid adapted to overlie the cap and having a depending annular flange extending outside the cap rim and adapted to overlie the said ledge.

In testimony of which invention I have hereunto set my hand, at Philadelphia, on

this 23rd day 0 December, 1907.
