BOTTLECAP.

SPECIFICATION forming part 0f Letters Patet NO. 614,942, dated November 29, 1898. Application led August 27, 1898. Serial No. 689,667. (N0 mOdel.)

To @ZZ whom it may concern:

Be it known that I, LoUIsA GREBE FLANI- GAN, of Baltimore city, in the State of Maryland, have invented a new and useful Improvement in Bottle-Caps, of which the following is a specification.

My invention relates to that class of bottle-stoppers which close the mouth of the bottle by means of an external metal cap provided with an interior elastic washer, which cap is forced down to compress and tighten the washer over the mouth of the bottle, and the lower edges of which metallcap are then spun or compressed around an external flan ge or enlargement near the mouth of the bottle to retain the cap in place and hermetically seal the bottle.

My invention consists in a cap formed with .a circumferential inturned flange around its upper and outer edge, which is adapted to receive the end of a tool to pry off the cap and which also makes a strong reinforced edge or crown for the bottle-mouth which protects it from breakage.

It also consists in the combinatiomwith said cap, of a disk or plate secured beneath the inturned flange and having a proj ectingthumbpiece or lug to avoid the use of a separate tool on removing the cap, as will be herein,

after fully described;

Figure l represents three stages in the formation of the bottle-cap. Fig. 2 is a side view of the cap applied to a bottle-neck. Fig. 3 is a vertical section through the cap and bottle-neck. Fig.4 is a plan view of the cap. Figs. 5 and G are views similar to Fig. 3, but showing modifications of my invention.

A is the bottlecap,which is preferably made of sheet metal. 1t is formed around its upper circumferential edges with a standing flange or crown c2, which is turned inwardly toward the center of the bottle. This leaves the central top portion of the cap slightly depressed, and the space within the depression is of greater diameter at the bottom than it is at the top. The sides of the cap extend downward in the form of a pendent skirt, forming a hollow cupped bottom that incloses the bottle-neck. Inside the cap there is the usual elastic washer B, which may be made of cork, rubber, leather, wood, Celluloid, or any other desired material.

The cap is applied to the bottle in the usual way of caps-i. e., it is forced down over the mouth of the bottle to compress the elastic washer against the mouth of the bottle to tightly close it-and the lower edge of the cap is then spun, compressed, or otherwise clenched around the external bulge or swell e, formed in the glass.

My invention has no reference to the manner of closing the bottle, but only to the manner of removing the cap and forming a better protection to the mouth of the bottle, and for this purpose the inturned circumferential flange or crown d2 plays an important part, for its inturned edge affords a purchase for a tool having a round chisel-shaped edge fitting beneath said flange, as shown at if in dotted lines in Figs. 3 and 4. When such a tool is thus applied, its end catches under the flange at one side of the cap, and the side of the tool fulcrums on the flange at the other side of the cap, and when strained in the direction of the arrow in Fig. 3 it dislodges the cap from the projection e on the mouth of the bottle in a simple and practical way. Not only is this result obtained, but this standing flange forms a reinforced crown extending all around the edges of the mouth of the bottle and protects it against being chipped by accidental abrasions or blows.

To form my bottle-cap, it is struck up from sheet metal rst in a plain cup shape, as at a, Fig. l, and then in a second stamping operation the standing peripheral flange of double thickness is raised, as at d', and then in a final operation this standing flange is swaged inwardly by a concave or hollow cone die, as seen in dotted lines at d.

When it is desired that the bottle shall be provided with its own opening devices, I simply place a plate or disk C or C', Figs. 5 and 6, on the top of the partially-formed cap a', and then when the swaging-die d turns the lian ge inward it securely locks this disk to the top of the cap. This disk or plate is formed with a laterally-projecting thumb-piece c, as in Fig. 5, or with a vertically-'extending and perforated tang or lug c', as in Fig. 6, either IOO "gof which forms afford aconvenient hold for ils ` pulling olf the cap.

In making use of my invention I would have it understood that I do not confine it to bottles alone, as it is equally applicable to jars, cans, or any other form of vessel capable of being closed by such cap, and I intend to so apply it.

In defining my invention With greater clearness I would state that I am aware that a sheet-metal pail has been constructed with an inturned upper edge inclosing a Wire and a cover Which has an annular depression which is adapted to be forced under the marginal inturned edge of the pail by a special inachine. This construction is essentially different from mine, as is also its mode of action. In my invention the cap With the inturned flange along its circumferential edge is formed complete before it is applied to a bottle, whereas in the construction referred to the cover is expanded beneath the overhanging edge of the pail after said cover is applied. Furthermore, in my construction the inturned flange surrounding the cap is of two thicknesses of metal that lie flat against each other, forming a stiff reinforcing crest or crown Which is stout enough to form a firm dislodging hold for the tool, While in the pailcover the bends are not in contact, and one of them incloses the inturned head or Wire at the edge of the pail, so that it could not be dislodged by a tool, as in my case, for the reason that the tool end Would underlie the wire head at the margin of the pail.

Having thus described my invention,what I claim as new, and desire to secure'by Letters Patent, is-

l. A bottle-cap having on its upper edge a circumferential inturned flange formed of Walls of double thickness lying flat against each other and an open space Within the flange of greater diameter at the bottom than it is at the top, and aV pendent skirt adapted to inclose the neck of the bottle substantially as and for the purpose described.

2. A bottle-cap having on its upper edge a circumferential inturned flange formed of walls of double thickness lying flat against each other, a central depression on top of greater diameter at the bottom of the flange than it is at the top, and a cup-shaped bottom substantially as and for the purpose described.

3. A bottle-cap having on its upper edge a circumferential inturned flange of double thickness forming an inner space of greater diameter at the bottom than it is at the top, substantially as and for the purpose de scribed.

4. The combination of a bottle-cap formed with a circumferential inturned flange around its upper edges, and an attached dislodgingplate retained beneath the inturned flange substantially as and for the purpose described.
