Specification of Letters Patent.
Patented July 1, 1919.
Continuation of application Serial No. 841,808, filed May 27, 1914. This application filed April 27, 1917. Serial N o. 164,832.
.. cured on Ibottles 'and jars having screwthreads or lugson the neck, and which closuresv are providedl with projections extending inward and arranged in the form of partial screw-threads, to engage the lugs and cause the closure to bescrewed securely down on the top of the bottle.
One object of the present invention is to provide a kind of lug that is formed by bending upwardly projections lon the cap flange, in such a manner .that each 1u will present a raw edge in-position to direct y engage the lug or thread on the 'bottle neck, and each lug will also present a bent portion of the projection to engage the thread on the bottle.
A further object of the invention is to provide a form of the thread engaging projection thatis so disposed relative to the .screw-thread on the bottleneck that the pitch of the threads in the two cooperating members are slightly different, whereby the projection will first engagewith the thread' Ion the bottle at the portion provided with the raw edge, and upon further application A of the closure by screwing it down, the projection will slightly yield at the engaging portion to cause-engagement throughout the extent of the projection with the bottle thread.
A further object is to provide in connection with the described form of cap, strengthening means extending around the flange adjacent the said projections, in the nature of a rib or corrugation. A
In the accompanying drawings showing embodiments of my invention, Flgure 1 is a vertical central section through the closure before the flanges are bent up to their final form. Fig. 2 is a similar view of the finished closure, with the jar threads indicated. Figi 3 is a fragmentary bottom plan View of the closure. Fig. 4 is a fragmentary section enlarged on the line 4--4 of Fig. 3. Fig. 5
is a fragmentary section enlarged on the line 5 5 of Fig. 3. Fig. 6 is a fragmentary section enlarged on the line 6-6 of Fig. 3. Fig. 7 shows a section of a modification, with the projections before bending, and Fig. 8 shows the same in the bent form. Fig. 9 is a fragmentary bottom plan of the elosure shown in Fig. 8. Fig. 10 is an enlarged section on the line 10-10 of Fig. 8. Fig.
11 is an enlarged section on the line 11-11.
of Fig, 8. Fig. 12 is an enlarged section on the line 12-12 of Fig. 8.
In the arrangement shown in Figs. 1-6, I provide a cap comprising atop 18 and a flange 19 of cylindrical form, on the bottom of which are series of projections 20, four being shown. Each of these projections is so formed that when it is bent over inwardly at an angle to the top plane of the cap it will be inclined thereto, and will also be curved corresponding to the cylindrical curve of the flange; and further the edge of the margin is given a kind of roll or bend whereby one portion,l as at 21, will present a raw edge of the projection to the thread y22 of the jar, as indicated in Figs. 2 and extending farther toward the flange portion 19. At the other end of the projection the bend extends still farther in the form of a roll or bead, as indicated in Fig. 6.' It will be further observed from these three sectional views, that as the bend approaches the projection, it is located a greater distance from the top. By reason of this construction of the projection or lug, the portion 21 will present a raw'edge 'to engage the thread on the jar, while the other Vtwo portions will present practically a bent edge or portion.
It will be further seen from Fig. 2 that the angle which the portion of the lug that engages with the thread 22, makes with the thread, is of a slightly different pitch or inclination, whereby the portion 21 of the projection which has the raw edge formation, will first engage the thread. 22. Upon further application of the cap this part of the projection will yield slightly suficient to cause engagement with the bottle thread throughout the length of the projection.
In Figs. L12 is shown a' modification in which a cap having the ange-26 is provided with projections'27 that have one side edge abruptly inclined at 28, and the opposite side at 29 having a very gradual incline or slope, and the projection is further provided with an abrupt shoulder at 30, where by one portion 'of the projection extends for a greater depth from the top of the cap than the other portion, when the projections are Vfirst formed, as indicated in Fig. 7. Vhen thesev projections are -rolled inwardly at an incline to the top of the closure, a raw edge will be provided at 3l adjacent the inclined side edge 29 of the projection, as indicated in Figs. 9 and 10. The portion beyond the shoulder 30 willbe bent inwardly as indicated at 32 in Figs. 9 and 12. The intermediate portion 33 is indicated in Fig. 11.
This projection in its final form may also be given a pitch slightly different from the pitch of the thread 34C on the bottle neck, as indicated in Fig. 8.,
When either of these forms of closures are applied to a threaded bottle neck, the raw edge will cause the projection or lug to engage with a Very strong friction that will assist" in securely retaining the closure on the jar. The projections will also yield and cause engagement throughout the eX- tent of the projections, with the threads or lugs on thebottle neck.
Having thus described my invention, what l claim is 1. A.. closure for a storage vessel coinprising a flanged cap having a plurality of' pro-n jections each bent over inwardly to orin lugs on the inside oil the flange adapted to engage the screw tl'iread on a jar, each lug presenting to the thread an initially en gaged raw edge of the projection and also a bent portion of the projection adapted to be pulled inwardly' toward the by said raw 1 edge.
