C. HAMMER.

BOTTLE OR JAR CLOSURE.

APPLICATION FILED AUG.8. 1912.

Patented Nov. 16, 1915.

Inventor Attorney CHARLES HAMMER, OF BROOKLYN, YORK.

BOTTLE OR JAR CLOSURE.

Application filed August 8, 1912.

To all whom it may concern:

Be it known that I, CHARLES HAMMER, a citizen of the United States, residlng at Brooklyn, in the county of Kings and State of New York, have invented a new and useful Bottle or Jar Closure, of which the following is a specification.

This invention relates generally to bottle or jar closures, and particularly to a closure for use with a jar or bottle having separated, inclined threads in place of a single continuous thread.

The principal object of the invention 1s to provide an improved form of 1n:pre ssed rib or projection to engage the lnclined threads of the jar or bottle.

With the foregoing and other ob ects in view which will appear as the descrlption proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of 1 nvention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawing forming part of this specification, Figure 1 1s a side elevation of a jar or bottle havlng a cap provlded with the improvements of the present invention; Fig. 2 is a side elevatiorrof the upper end of the jar or bottle showing the inclined threads; Fig. 3 is a vertical section through the upper end of the bottle neck and cap; Fig. 4 is a section through the cap on the line of Fig. 3 showing the shape of the iii-pressed projection; Fig. '5 1s an enlarged view showing in perspective one of the in-pressed ribs or notches.

Like reference numerals indicate corresponding parts in the different figures of the drawing. 1

The reference numeral 1 indicates the neck of a jar or bottle and 2 an annular rib thereon. Extending upward from the rib 2 1s a plurality of inclined separated threads3. The bottle cap 4 is formed wlth a top 5 and a depending annular flange (5. The flange 6 is formed preferably with series of out-- punched corrugations 7 and a plurality of Specification of Letters Batent.

in-pressed ribs or projections 8. I also provide the top 5 with a stiffening rib, shown clearly in Fig. 3, in the top of the same, this rib being punched so as to extend downward from the inner face of the top.

As shown clearly in Fig. 4, each of the projections 8 has a shallow end 9 and a deep end 10, and, as indicated in Figs. 1 and 5,

a each rib is narrow at the end 9 and widens or flares outwardly toward the end 10. The lower edge of each notch 8 is parallel with the rolled or beaded edge 12 of the fiapge 6,

and the upper edge 14 of each rib 1s up-- usual manner, so that the ribs 8 extend in between the groups of threads 3, after which it is only necessary toturn the cap to cause the ribs of the cap to engage the ribs or threads of the jar or bottle.

As illustrated particularly in Fig. 2, the threads 3 are arranged in pairs, and the members of each pairare placed one above the other and are of substantially the same length or coextensive with each other. When the cap is screwed on, each one of the projections 8 will be engaged by one pair of threads 3, and will pass between the members of the pair; but will bind principally against the lower portion of the uppermost to hold the cap tight on the jar or bottle. This is because the upper portion 1+l of each projection is inclined to correspond to the pitch of the threads; while the lower portions of the projections are preferably formed so as to lie quite close to the rolled edge 12 over the greater part of their lengths from the ends 9 to the ends 10, the latter ends being made wider than the former mainly for the purpose of glvlng the necessaryslope to the 100 projections without unduly spacing or separating the ends 10 from the rolled-edge 12. The utility of this construction resides in the fact that a set of projections having the shape and position just described are capable of enabling the rolled edge 12 to resistv buckling of the flange and other deformatlons of the cap to best advantage. For example, when the cap is made to engage the threads 3 securely, the downward pressure of the upper threads 3 on the upper portions 1.4? is transmitted to the lower portions of the projections and by such lower portions is given more of an outward direction. If the lower portions were not arranged close to the edge 12 over nearly the whole length of the projections, this outward component of the pressure in question might take effect all at one point and produce a sharp bend or shoulder in the rolled edge. But by the arrangement above set forth, such a concentration of the deforming stress is prevented, and the pressure is exerted across nearly the whole length of the lower portion of each projection 8' upon a considerable section of the length of the rolled edge, and the lia bility of buckling or the like is consequently obviated. The same desirable effect might be obtained, though in smaller degree, by making the lower portions of the projections parallel with the upper portions 1-1, and

causing the ends 9 to indent the rolled edge slightly; whereby the greater part of the lengths of the lower portions would still be close enough to the rolled edge to insure a good reinforcing action by the edge 12. It is only necessary that the slope of the projections be not too great; so as not to space the ends 10 too far from the edge 12.

While Iprefer to use the cap shown and described herein along with the type of threads. shown particularly in Fig. 2, 1 wish to state that my cap may be employed with other designs of threads as well; particularly when such other designs of threads involve a plurality of pairs of threads so arrangedas to receive the projections 8 between the-members of the pairs.

What is claimed is:

1. A cap comprising a top and a flange, theflange having inwardly extending ribs or projections, each of which is deep at one end and shallow at the other end, the upper edge of each rib being downwardly inclined with relation to the topof the cap.

A cap having inwardly extending ribs,

' each of which is narrow and shallow at one threads, of a bottle cap comprising a top and flange, said flange having therein a pluing narrow and shallow at one end and wide and deep at the other end, the lower edge of each rib being parallel with the lower edge of the flange and the upper edge ot' each rib being parallel with the pitch of the separated threads and downwardly inclined with relation to the top of the cap, substantially as described.

4. A cap having a flange provided with a strengthened edge,said flange having corrugations terminating short of the edge and one or more inwardly extending projections located between the edge and the corrugations, said projections being relatively'narrow and shallow at one end and relatively wide and deep at the other end, the lower edge of the projections being substantially parallel with the strengthened edge and the upper edge being inclined thereto, the relatively wide ends of the projections extending entirely across the space between the corrugations and said strengthened edge.

5. The combination with a storage vessel having a mouth and a plurality of pairs of inclined, separated overlapping threads adjac'ent said mouth, of a closure comprising a top and a flange, and having a plurality of inwardly extending-projections on said flange, said projections having inclined upper portions, and being located at the same distance from the top, said projections alsobeing adapted to be received between the threads of each pair to'secure the'closure to the vessel;

6. A storage vessel having a mouth and a plurality of pairs of inclined, separated threads arranged atintervals around said mouth, the threads of each pair being placedv side by side and being substantially coextcnsive with each other.

7. A closure for a storage vessel compris ing a top and a flange, the latter having a strengthened edge and one or more projections on its inner face, said projections extending circumferentially of the flange, and having their sides toward the top inclined with respect to the top, and'their opposite sides placed relatively close to the strengthened edge over nearly the whole length of said opposite sides. a

8. A closure for a storage vessel comprising a top and a flange, the latter-having a strengthened edge and one or more projections on its inner face, said projections extending circumferentially of the flange, and having their sides toward the top inclined with respect to the top, and their oppositessides arranged relatively close to and parallel with the strengthened edge over nearly the whole length of said projections.

9. A closure for astorage vessel, comprising a top and a flange, the latterhaving its edge turnedover in order to strengthen the same, and having one or more projections In testimony that I claim the foregoing on its inner face, said projections each beas my own, I have hereto afiixedmy signaginning at said turned edge and extending ture in the presence of tWo Witnesses.
