BECEPTACLE CLOSURE.

Application filed December 27, 1922. Serial No. ,%0.

To all whom it may concern:

Be it known that IGNATIUS J. CELoNA, a at Brooklyn, in the county of Kings and tate of New York, has invented certain new and useful Improvements in Receptacle Closures, of which the following is a specification.

Ihe present invention relates to improvements in receptacle closures and more particularly resides in a novel construction and formation of the lower free edge of the flange of a metallic cap or closure, whereby a double bead is provided producing rigidity in this edge of the flange, preventing rust which is unsightly and insanitary and giving the article a neat and attractive appearance by concealing the raw edge of the metal between the two beads. E

Another object of the invention is to provide an improved receptacle closure or jar cap in WhlCll the objectionable squareness will not be apparent from the exterior; In receptacle closures of this class, either interrupted threads or inner projections are provided upon the flange of the cap for the purpose of cooperating withcomplementar construction of the bottle neck to the .en that the cap may be efiectually held in place. These projections and threads are usually four in number and are spaced approximately degrees-about the circumference of the cap so that the'stresses set up in the material when these threads or projections are engaged with the bottle neckcause the cap to assume a square formation and this, according to the present construction which involves the use of only a single bead, is objectionable not only from the standpoint of appearance but it creates gaps and crevices in the bead into which fluid gets causing corrosion. In the present constructions which employ only a single head, and which constructions are extensively used in practice today, the raw edge of the material is rolled into the head or against the flange of the cap but it is always exposed and because it is unlacquered it rusts readily. The present invention proposes to remedy these defects by concea ing the raw edge from fluid and by imparting an added rigidity to the lower edge of the cap flange.

Other objects of the invention are to strengthen the construction without materially adding to the weight or expense; and in general to provide an attractive cap using a minimum of material andfashioning this material in an improved way to afford aresultant construction in which the lower part of the depending flange will present substantial perfection in its roundness when actually upon the receptacle and which will retain this roundness and as a consequence remain substantially efiective against any leakage ,or rusting or deterioration of the With the foregoing and other objects in view, the invention will be more fully described hereinafter, and will be more par ticularly pointed out in the claims appended hereto.

In the drawings, wherein like symbols refer to like or corresponding parts throughout the several views,

Figure 1 is a fragmentary side view of a bottle or jar showing the improved cap in place thereon.

Figure 2 is a central section view taken through the improved cap.

Figure 3 is a bottom or inside plan view of the cap showing the double bead, and

Figure 4: is an enlarged fragmentary sectional view showing the formation of the double bead.

Referring more particularly to the draw- "ings 5 designates generally a bottle, jar or other receptacle having a usual form of neck to cooperate with the divided threads 6 shown upon the depending flange 7 of the cap or closure. This cap or closure is made with a top portion or disc 8 extending across the mouth or the opening of the receptacle and being usually formed of tin or other sheet metal from which the flange 7 is turned downwardly at substantially right angles forming a relatively shallowcylinder. This cylinder or flange 7 envelopesa portion of the receptacle neck or mouth and it wild be clear to those skilled in this art that the method of applying this cap is by interfitting the divided threads and partially rotating the closure, the method of removal being just the reverse. For this purpose the upper portion of the marginal flange is corrugated as indicated at 9 to enable a firm grasp to be had-a'nd for ease in applying and removing.

' In accordance with the. invention the flange 7 of the cap is made unusually deep in order to provide sufficient metal for the purpose of providing the double bead. The

additional or excess metal provided for this purpose is initially turned outwardly and returned upwardly in a substantially vertical direction and: in approximate parallelism with the lower portion of the flange 7 so that an inner bead 10 is provided which is substantially concentric with the flange-7 and which overlaps and is in direct-and firm contact'with. an appreciable exterior area of the lower portion of said flange 7 This inner bead-materially reinforces the lower edge of the flange and, dueto its contact with the outer flange-wall, strengthens the flange at this point and resists any tendency to squareness in the flange not only at this lower edge but also throughout its entire depth. 'The excess or additional material from the upper edge of this inner bead is carried outwardly and downwardly in a comparatively wide sweeping curve and an outer bead ll is formed thereby spaced from the inner head 10 a considerable distance and being entirely closed at its top portion to avoid the entranceofmoisture or fluids.

The bulge given the material in'the formation of this bead will also add considerably to the strength and resistance at this point and-it will be noted that the outer bead 11 1 is substantially concentric with the inner head 10. The relative formation of these adjoining the raw edge 12 lying against the parts provides an internal space between the inner and the outer beads which as has been stated, is entirely closed at the top andv lower portion of the inner bead 10. Due to the fact that a close state of contact exlsts between the inner bead '10 and the adjacent portions of the flange 7 no liquid .or foreign matter is able to find its way between these parts, but it will be remembered that these surfaces are lacquered and consequently corrosion will be prevented. The unlacquered surface of the raw edge 12 however is protected against corrosive action. Added strength is secured by the use of the four thicknesses obtained from the formation just described.

Oftentimes in prior constructions, due to the nature of the construction itself and im perfect manufacture, the threadsupon the cap will not catch upon those of the bottle but the threads will slide off. This is quite frequent because the flange is allowed to spread or stretch diametrically. However the outer coiled bead or wall 11 in the present construction will be effective to cure this defect and avoid any likelihood of the threads slippin or sliding over one another.

Attention is invited to Figure 3 in which the neatness and'compactness of the flange or bead construction is shown from beneath. The construction presents practically a double flange or bead in which a tight joint is made between the two not accessible to water and moisture and in the cross section in Figure 4, the construction is shown to be made up of practically four thicknesses of material with the added strength given by curving or coiling the outer wall or flange 11.

It is obvious that various changes and modifications may be made in the details of construction and design of the above s ecificallyv described embodiment of this invention without departing from the spirit thereof, such changes and modifications being restricted only by .the scope of the following claims.

What is claimed is:

1. A jar closure of the lacquered type having a flange with means to secure the closure upon the jar, said flange having an inner bead bent outwardly and upwardly from the lower edge of the-flange and being substantially concentric with the lower portion of the flange, an outer bead in one piece with the inner bead and spaced from the inner bead, said outer bead being formed by bending the material from the upper edge of the inner bead outwardly and downwardly to provide a space between the beads and to enclose this space from above, the raw edge of the material being turned inwardly into the space between the two beads.

2. A receptacle closure of the lacquered type having a flange provided with threads whereby to secure the same to the receptacle, said flange having-a pair of concentric beads located exteriorly and concentrically of the flange, said beads being in one piece and having a connecting portion between the upper edges of the-beads, said beads being separated and the inner bead being pressed closely against the exterior wall of the flange, the raw edge of the material being rolled in a substantially closed loop inwardly between the two beads.

3. A receptacle closure comprising a to portion, a depending flange having indente threads, said flange having its lower edge returned upon itself to provide an inner wall, and being coiled from the upper edge of said wall outwardly and downwardly, with its extremity turned inwardly against said inner wall and forming a seal therewith.

In testimony whereof I affix'my signature.

IGNATIUS J. OELONA.
