a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to certain improvements in receptacle closures, and more particularly to closing caps of the type commonly known as bottle stoppers which embody means whereby the cap can be released and removed from the receptacle by the fingers without requiring the employment of an opener or other tool; and the objects and nature of the invention will be readily understood by those skilled in'the art in the light of the. following explanation of the accompanying drawings illustrating what I now consider to be my preferred embodiment from among other formations and arrangements within the spirit and scope of my invention.
I-Ieretofore bottle stoppers, or receptacle closing caps have been constructed with a depending flange adapted to be compressed or spun under. the exterior shoulder of the bottle mouth to contract said flange or place the same under a tension in locking the cap to the bottle month, said flange being partially severed but held in contracted locked condition by the neck of a handle or finger piece cut from the cap top and normally arranged in the plane thereof, the arrangement being such that to release the cap it was necessary to bend the finger piece up and detach the same from the cap by severing or breaking said neck, thereby breaking the continuity of said flange and permitting the same to expand for removal from the bottle month. However, the handle or finger piece having been completely detached from the cap, it was often exceedingly awkward and difiicult to remove the cap from the bottle mouth even after the same was thus broken and loosened by expansion.
' It is an object of this invention to provide such caps with means and arrangements whereby the continuity of the flange or ring of the cap can be readily broken by the handle or finger piece without detaching through which the expanded or loosened cap can be readil and convenientl stri ed from the bottlz. y pp A further object of the invention is to provide a cap having a finger piece integral WllZh' its top, and with said top so formed that the connecting ligament holding the cap aga nst spreading, is arranged directly in the line of the cut forming said finger piece, wh le the finger piece is otherwise secured and connected in the top, and serves as a lever for readily severing or breaking said llgament and without tearing or breaklng themetal otherwise connecting the finger piece in the cap.
A further object of the invention is to produce a cap whose construction not only permits of its quick and rapid removal from the bottle mouth, but whose finger piece remaining integral with the top of the cap, serves both as a lever to break the connecting portion which holds the cap against spreading, as well as a handle, by which the cap may be lifted from the bottle after the connecting portion has been severed.
The invention consists in certain novel featuresin construction and in combinations and arrangements as more fully and particularly set forth hereinafter.
Referring to the accompanying drawings :--Figure 1, is a perspective view of the neck portion of a bottle closed by a cap. em-
bodying my present invention. Fig. 2, is a perspective View showing the finger piece swung up preparatory to twisting or exerting the lever action thereof to sever or break the cap connecting ligament. Fig. 3, is a perspective view showing said ligament broken and the cap expanded or loosened for removal. Fig. 4., is a top plan view of the cap as it appears in Fig. 1. Fig. 5, is a top plan of the cap as it appears in Fig. 3. Fig. 6, is a sectional view of the cap of Fig. 1.
In the example illustrated by the drawings, the cap of my invention is struck up, pressed, or otherwise formed, of suitable sheet metal with a depending annular flange 1, and a horizontal top flange 2, formed b encircling cut 3, in the cap top that orms the handle or finger piece 4, the horizontal flange being divided by the neck or connecting portion 40, integral with the flange 2, and the finger piece 4, and arranged about radially o the ca top. This neck or connecting portion is o substantial width. 0
The depending flange of the cap is completely severed at one point by the cut 10, extending transversely thereacross and continued transversely of the cap top flange 2 in that portion thereof opposite the neck 40, so that the upper inner end of sald cut 10, is located closely adjacent to one end of the cut 3, leaving the narrow ligament 30, between said upper end-of the cut 10, and sald adjacent end of cut 3. The narroyx ligament forms the connection complet ng the circle or ring of the cap and holdlng the same and the flange 1, against expansion. The opposite end 31, of the cut 3, may be rounded and enlarged about as shown, and
the upper inner end 11 of the cut 10, may
also be enlarged and rounded about as shown. It will be observed that the cut 10, extends to a point immediately between the ends of the cut 3, and in the line or circle of said out, so that the connecting ligament 30, is in the line of said out 3, or in the line of a continuation of said out; or in other words in the plane of said out. p
In practical use, the cap so far described, usually contains an inner imperforate sealing cap or disk a, containing or provided with a suitable sealing means as disk b, to compress on the bottle mouth as shown in Fig. 6. The cap of Fig. 1, is then usually applied to the bottle mouth under heavy pressure, or otherwise, and the lower edge of its flange 1, is then pressed,'bent, or spun under the exterior shoulder of the bottle mouth to lock thecap in position and to contract or place the same under tension.
To release the cap, the finger piece, is bent up to about the position shown by Fig. 2, and is then slightly twisted or rocked to exert a lever action on the ligament 30, for breaking the same. The ligament is readily severed or broken by this twisting or lever movement of the finger piece, so that the parts will assume about the position shown by Fig. 3,-with the finger piece remaining firmly attached to the cap through the medium of the connecting portion 40. As soon as the ligament 30, is broken or severed, the cap as a whole loosens or expands on the bottle month by reason of the slots 9, in the top horizontal flange 2, so that the same can be readily stripped or removed therefrom, through the medium of said finger piece. It will be noted that this finger piece remains positively attached to one end of the broken or severed cap and that the cap can be thereby readily released from the bottle mouth by a stripping action beginning at said end to which the finger piece is attached.
The twist or movement of the finger piece necessary to break or sever the connecting ligament, is so slight that no substantial breaking or severing stress or strain is applied to the ortion of the metal connecting the finger piece to the cap, and the avoidance of any tearing or severing strain on said portion 40, may be absolutely prevented by rounding or enlarging the ends 31 and 11, of the cuts 3 and 10, that form'the boundaries of the connecting portion 40, although in commercial practice it may be found advantageous to eliminate these rounded portions to simplify the mechanical construction of the tools that produce the cap without sacrificing any of the advantages which the said rounded portions may possess; hence I do not care to limit myself to any particular mechanical construction of the cap in this particular.
In order to permit the finger piece 4:, to move freely through the encircling cut 3, in,the to horizontal flange, I preferably form sai finger piece with a head 8 located in close proximity to the edge of the finger piece, so that when the bead is stamped up into the finger piece it will draw the metal of the finger piece away from the edge of the cut 3, in the cap top, and thus allow the finger piece free movement through said out; otherwise, the finger piece would bur and stick somewhat in its movement, and would not lie flush with the top of the horizontal flange, which would be ob'ectionable when fastened .on the bottle. urthermore, by beading the top of the finger piece as outlined, the fingers are prevented from slipping in the act of mampulating the finger piece in the removal operatlon. Therefore, the heading of the finger piece performs a twofold result.
What lclaim is 1. A stifl metal closurering-br .cap composed of a vertical flange, a horizontal flange, and a finger piece partially severed from the horizontal flange by a circum ferential cut,-the horizontal flange having radial slits therein one of which is extended through the vertical flange, said last mentioned slit being separated from the circumferential cut forming the finger piece by a narrow strip of metal on one side and by a wide strip on the other side, whereby the twisting of the finger piece breaks the continuity of the horizontal flange and allows the cap to expand without separating the finger piece from the cap.
2. A stiff metal closure ring or cap composed of a finger piece partially severed therefrom,and integrally connected thereto by a wide strip of metal on one side and by a narrow strip of metal on the other side, a vertical flange, and a horizontal flange, said horizontal flange having cuts therein to enable the cap to expand, said flanges having a cut extending completely therethrough except for said narrow strip of metal which maintains the continuity of the cap, whereby the bending of the finger piece severs said narrow strip of metal and breaks the continuity of the cap and allows the cap to expand without separating the finger piece from the cap.
