CATSUP-CAP.

Specification of Letters Patent.

Patented Feb. 1, 1921.

Application filed. December 22, 1919. Serial No. 346,579.

To all whom'z't may concern.-

Be it known that I, CHARLES HAMMER, a citizen of the Unitedstates,- residin at Queens, in the county of Queens and tate of New York, have invented certain new and useful Improvements in Catsup-Caps, of which the following is a specification.

This invention relates to closures for containers of various styles, particularly the form of caps employed with bottles having narrow necks.

"One of the objects of this invention is to provide a form of bottle closure made from a blank bent to a cylindrical shape to form a body with one end closed by a disk; in which the body at its lapping end is provided with holding means at the top and bottom only of the cylinder, with the lapping margins merely in contact without any means of interlock or interfold, the raw edges of'the blankends being merely doubled back on themselves on the inside of the meeting ends, and out of engagement, and which holding means for top and bottom portions of the lapping ends, will prevent relative sliding movement of one body end portion on the face of the other body end portion, in a direction parallel with the ends of the blank, especially during manufacture.

A further object of this invention is to arrange the lapping ends so that their edges are merely doubled back inwardly between the lapping portions without engagement, to cause but three thicknesses of metal at these lapping portions between the top and bottom; whereby the corrugation of the body to produce screw threads will not resultin an ugly bulge at such portion, as would result where an interfold or interlock between doubled margins is employed.

In the accompanying drawings representing embodiments of my invention, Figure 1 shows the blank for the body member.

Fig. 2 shows the blank with end portions slightly bent over.

Fig. 3 is an edge view of the blank.

Fig. 4 shows the blank for a modification.

Fig. 5 shows the latter with the ends bent.

Fig. 6 is a vertical section through the closure.

Fig. '7 is a partial vertical section enlarged on the line 77 of Fig. 6.

Fig. 8 is an inside view enlarged of the top and bottom of the body blank before the end disk is applied.

Fig. 9 is a cross section on the line 9-9 of Fig. 8.

Fig. 10 is a cross section on the line 10-10 of Fig. 8.

Fig. 11 shows the finished closure in perspective.

In Fig. 1, I show a blank in the form of a strip 1 having one end bent over to form a channel 2, the end portions 3 and 4 of the bend being inclined as shown. At the other end of the blank one corner portion 8 is removed, and the two square corners 10 and 11 are bent down on-obhque lines on the outer face of the blank to form hooks 12 and 13, see Figs. 2 and 3. It will be noticed that these hooks are in proximity to the longitudinal edges of the blank, and extend in 0pposite directions. The blank is then bent into the form of a cylinder with the face 14 outward, and the hooks 12 and 13 are caused to engage the inclined end portions 3 and 4 of the channel 2 at the other end, as indicated in Fig. 9. The joint is now pressed strongly together, as indicated in Figs. 9 and 10, and the portion of the channel 2 between the hook portions 12 and 13 will be bent tight against the face of the blank.

The end of the body thus formed into a cylinder, is closed by a disk 15, that is caused to interlock with the edge of the body by an interfolded joint of the well known form, such as set forth in U. S. patent to Kind, No. 321,822, of 1885. This is indicated in Figs. 6 and 11, and the hook portion 12, with the engaging portion of the channel 2, is located so that it will be included in this interlock with the top 15.

At the lower margin of the closure the edge is bent outwardly to form a bead or wired edge 16, and the hook 13, with the engaging portion of the channel 2 is included in thiswired edge, as shown in Figs. 6 and 7.

The lower portion of the closuremay be provided with corrugations extending around in the form of a screw thread 17, as shown. But this threaded portion terminates just above a short cylindrical portion 18 adjacent the bead 16, and which is made of sufficlent in ternal diameter to pass over the screw threads on the bottle neck.

It will be understood that the placing of the hook portions that engage the ends of the channel portion in the upper and lower bent edges of the body, cause a secure fastening, and also serve to obscure the slight extra thickness caused thereby, also are free from the screw threaded portion.

In the process of manufacturing a cap of this character, the strip of sheet metal, previously bent at one end to form a channel with oblique ends, and having at the other end a pair of hooks that extend oblique to the transverse end of the blank in opposite directions, is first bent around to a cylindrical form to bring the hook and tongue portions slightly past each other as lapped. whereby the hooks are caused to enter into the bent-channel portion, and the cylindrical body is then enlarged in diameter to tightly engage the hooks and channel. and finally bumped by a plunger on the engaging portions, and the hooks and bent tongue portion are pressed fiat.

If the end portions were merely interlocked by a bent channel on each body end, they would have a sliding movement of one end portion on the other, and one edge might be advanced beyond the other, and

, when the end disk is inserted and interfolded, an irregular cap would result. This difiiculty is overcome by means of my ohlique hook portions, that engage the oblique ends of the bent tongue, so that as soon as the hooks engage the tongue, this edgewise movement is absolutely prevented.

These hook portions being at the top and bottom edges, will be included in the bead at the open end, and also in the interfolding with the edge of the top disk. By. this arrangement substantially the entire lapping end portions of the body member, between the top disk and the wired lower edge, are free of all forms of interlocking or interfolding means, and the lapping end portions have merely the raw edges doubled over without engagement. Therefore, at no place, exceptthe two bent hooks, is there four thicknesses of'metal, as would result from an interlocking or interfolded joint, but only three thicknesses, between the top and bottom hook portions;

In Figs. 4 and 5, I show a slight modification in which the blank 20 has in addition to the removed corner portion 21 an extension 22in the form of a tongue with notches 23 and 24 at the ends. This tongue 22 is bent back to form a double portion 24. see Fig. 5, extending between the bent hook portions 26 and 27, that correspond to the hook portions 12 and 13. At the other end this blank has the bent tongue portion 28 corresponding to the bend 2. The construction of this cap is the same as the form described, except that between the engaging hook portions the two raw edges of the blank are doubled inwardly, and would appear substantially as shown in the section of Fig. 9.

This application is a continuation in part of an application filed by me April 23, 1919,

Serial Number 292,193.
