BOTTLE-CAP. I

Specification of Letters Patent.

Patented Aug. 17, 1909.

Application filed June 17, 1908. Serial No. 438,960.

To all whom it may concern:

.Be it known that I, ADRIAN M. MILLER, a citizen of the United States, residing at Augusta, in the county of Richmond and State of Georgia, have invented new and use ful Improvements in Bottle-Caps, of which the following is a specification.

This invention relates to im')roven1ei1ts in metallic caps or seals for bottles, the object of the invention being to provide a cap of that type having a rim shouldered to interlock with a shoulder on the bottle with means for conveniently extracting or re- 1novin it from the bottle neck, the construction of the cap bein such as to maintain while applied a tight sealing connection, while ermitting of a ready removal when a portion thereof is Withdrawn from engagement with the bottle shoulder.

The invention consists of the features of construction hereinafter full described and claimed, reference bein ha to the accompanying drawing, in wfiich Fi ure 1 is a erspective view of the neck of a ottle closed by my improved cap. Fig. 21is a side elevation of the same. Fig. 3 is a side elevation looking at the diametrically opposite side of the cap from that shown in Fig. 2 and showing the bottle in dotted lines. Fi 4 is a bottom plan View of the cap.

fteferring to the drawing, the numeral 1 designates the neck of a. bottle of that type provided with a loekin shoulder 2 arranged externally below t e rim edge of the neck, and 3 designates a bottle cap of that type comprising a crown portion 4 having a depending uncorrugated rim 5 to surround the neck above the shoulder, said rim bein provided at its lower edge with a corrugated flange or extension provided with indented portions or shoulders to interlock with the shoulder 2 and thus secure the cap to the neck.

In accordance with my invention, the rim 5 is provided with a flange or extension 6 extending about half way' around the circumference thereof, said ange or extension being corrugated or otherwise formed to provide a series of spaced shoulders or indented portions 7 to enga e the shoulder 2, said shoulders 7 being preferably formed in practice by crimpingthe flange through the action of a suitable machine into engagement with the shoulder on the bottle neck. At the diametrically opposite side of the cap the rim 5 isprovided with a similar flange around the surface of the rim, the transverse width .of the flange 8 being preferably equal to one-eighth, more or less, of the circumference of the rim. These proportions of the engaging flanges or extensions may vary, but the locking portion 6 should be in practice of a width to extend nearly, if not quite, around one-half of the circumference of the rim, while the portion 8, may vary in size as circumstances under different conditions may require. The portion 8 is formed with a series of locking shoulders or indentations 9 corres onding to the shoulders 7 and is provide with a depending extension 10 serving as a fin or tab or lever by which the portion 8 may e withdrawn from locking engagement with the shoulder 2 and the cap pried off the bottle.

It will be observed that by the construction and arrangement of the locking portions 6 and 8 above described, cut-away portions or recesses 11 are provided between the extreme adjacent ends of the locking port ions, or that the rim is free from looking flanges or extensions between such locking portions, so that thecap is confined on one side of its center by the locking flange 6 and on the opposite side of its center b the locking portlon 8, which grip the bott e s'e curely enough to maintain the cap firmly in position to secure a. seal against any ordinary internal pressure; When the finger tab or lever 10 is pulled outward and upward, and the locking portion 8 is thereby disengaged from the shoulder 2, it is obvious that the cap being free from other engaging projections on the same side as the portion 8 may be tilted upward and forced forward to move the lOCklIlg portion 6 out of engagement with the shoulder, whereupon the cap will be disconnected. The absence of locking portions along the surfaces 11 facilitates the removal of the cap, in that the cap is weakened on a line transversely between the same to permit the side of the body of a refractory cap on which the shorter flange is formed to bend on the line mw, Fig. 4, upward to the required degree to facilitate its extraction. This oper' ation is facilitated by leaving the rim uncorrugated-or unstiffened so that it will not oppose -an inhibitory resistance. As shown, the tab 10, however, is provided with longitudinal corrugations forming continuations of the locking corrugations of the flange 8.

' or extension 8, extending to a lesser degree caps of this character maybe removed with: out the use of auxiliary extracting devices.

Havin thus fully described the invention, what is c aimed as new is a A bottle cap comprising a. top provided with a dependln uncorrugated circular rim anges at diametrically 0p-- having locking posits sides thereof, said flanges bein c0rru ated to provide instruck shoulders or inter ocking engagement with a shoulder on the bottle neck, one of said flanges extending practically around one half the surface of the rim and the other a materially less distance around the diametrically opposite surface of the rim, leaving comparatlvely wide s aces between the opposing ends of said an es, whereby the cap and flange are wea (ened transversely between said spaces, and a finger tab or lever projecting from the shorter flange, said tab having longitudinal stifl'ening corrugations formin continuations of the corrugations of said s orter flange. In testimony. whereof I affix my signature m presence of two witnesses.
