\JAR OR BOTTLE CLOSURE.

Specification of Letters Patent.

Patented June 4, 1907.

To all whom it may concern."

Be it known that I, ALVIN M. CRAIG, of the city of New Haven, in the county of New Haven, State of Connecticut, have invented a new and Improved Jar or Bottle Closure, of which the following is a full, clear, and exact description.

My invention relates to improvements in the construction of glass jars, bottles and similar receptacles, and particularly to the closure for such a receptacle.

My invention is an improvement on that shown in the patent to Lazareff, No. 751,083, dated February 2, 1904. In the former patent referred to a fastening plate with projecting lugs is held in the bottle neck, being fastened by compressing the glass while still soft upon the plate or ring. In practice it has been found difiicult to do this and my invention is intended to produce a closure somewhat analogous to that shown in the Lazareff patent, but cheaper and more easily applied. I find that by providing a spring wire ring with lugs thereon and snapping this into a groove in the bottle which groove has a stop or abutment to prevent the movement of the wire, that the structure is very much cheaper, the jar or bottle is more easily made and the lugs by engaging corresponding lugs on the cap effect a satisfactory closure.

To these ends my invention consists of certain features of construction and combinations of parts which willbe hereinafter described and claimed.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar figures of reference indicate corresponding parts in all the views.

Figure 1 is a broken side elevation partly in cross section of a jar showing my improve ments. Fig. 2 is a detail plan of the fastening ring. Fig. 3 is an inverted plan of the cap and Fig. 4 is a cross section on the line 44 of Fig. 3.

The jar can be of any usual construction of jar or bottle except that in its neck near the top is a groove 11 which extends nearly around the neck, the ends of the groove being separated by a stop or abutment 12.

material and it can be made of a round wire or a flat strip, but it has at necessary intervals lugs 14 which are produced by flattening and thinning the ring and the lugs pro ject beyond the side surface of the bottle neck 11. The wire should, however, be smooth and plain on its inner edge, so that it will fit snugly against the bottle neck and will not wabble, as a corrugated wire, hearing only in spots, is inclined to tilt and permit air to enter.

The cap 16 is usually of lass but can be of any suitable material, and on its inner side are lugs which are inclined slightly as shown best in Fig. 4, and by placing the cap upon the bottle neck so that the lugs 15 are out of registry with the lugs 14, the lugs 15 will drop beneath the ring 13 and then by turning the cap laterally the lugs 15 engage the under sides of the lugs 14 and the cap is locked securely in place.

In order that the closure may be sure to be air tight it is well toput a gasket between the top of the bottle and the under side of the cap, as shown clearly in Fig. 1.

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

1. The combination with the jar or bottle neck having a groove in its outer side; of the spring wire having a plain inner surface to fit continuously against the bottle neck, and projecting lugs on its outer edge.

2. In a structure such as described, the

combination with the bottle neck having a groove therein, of a spring wire having its inner surface plain and continuous, to fit snug against the bottle neck and having at intervals projecting lugs which are thinned.

ALVIN M. CRAIG.
