BOTTLE-SEAL:

SPECIFICATION forming part of Letters Patent No. 664,636. dated Dembe' 25, 190e'.

v Application filed `Tannary 20, 1900. Serial No. 2,12ii.' No modal.) i

To all whom it may concern,.-

Be it known that I, WILLIAM E. HEATH, a citizen of the United States,1-esiding at the city of Baltimore,in the State of Maryland,have invented certain new and useful Improvements in Bottle-Seals; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable'others skilled in the art to which it appertains to 1o make and use the same.

This invention relates to certain improvements in bottle-seals; and the objects and nature of the invention will be clear to those skilled in the art in View of the following de- I5 scription and the accompanying drawings, which, however, show merely one example of a construction within the spirit and scope of my invention.

The invention consists in certain novel feazo tures of construction and in combinations and arrangements of part-s and details, as more fully and particularly pointed out and described hereinafter.

Referring to the accompanying drawings,v

Figure l is adetail perspective ofthe neck of a bottle sealed in accordance with my invention. Fig. 2 is a longitudinal section through the bottle-neck, showing the sealing disk or cork and the locking-plug therefor iu the po- 3o sitionA they assume before being compressed and locked. Fig. 3 is a view similar to Fig. l2, showing the parts com pressed and locked and the seal effected. Fig. 4 is a detail perspective, enlarged, of the cup-shaped metal plug, a portion of the plug being broken away to show that the portion thereof diametrically opposite the extractor-arm is free to collapse during the extracting operation. Fig. 5 is a detail perspective,enlarged,of the plug,show

4o ing a portion thereof bent or collapsed as a a result of the extracting operation. Fig. 6 is a bottom plan, enlarged, of the plug. Fig. 7 is a detail cross-section of the plug. Fig. 8 is a plan View of the sealing cork or disk.

43 Fig. 9 is a det-ached perspective of the lever extractor-arm and its attaching means. Fig. l0 is a perspective view of the upper part of a bottle-neck, showing the plug in the act of removal and illustrating how the plug can o bend or collapse at its edge or portion diametrically opposite the extractor-arm.

In the drawings, d is the, neck ofA a bottle, having the liquid-passage 0'.' and formed withl the annular seat or recess a" in its upper en around the mouth or open end of said liquidi passage. This recess has the depressed usu'; ally flat iioor, as seen clearly in Figs. 2 and 3. The surrounding wall of the liquid-passage is annularly (or otherwise, if need be) undercut immediately below the said oor of the top 6o recess to form the enlarged portion a3 of the' liquid-passage immediately below said door and above the annular stop shoulder or ledge d4, a short distance below said iioorof the said recess. This annular shoulder is preferably formed with a flat top face, and the diameter of the liquid-passage at the inner edge of said shoulder is less than the diameter of the passage at the inner edge of the floor of said top recess, so that the sealing element, such as 7o the cork or disk and the plug, can freely move past said top floor and yet willengage and be limited against farther downward movement by said shoulder, against which the seal is eected. The diameter of the liquid-passage is contracted from said shoulder downward a suitable distance. Usually, although not necessarily, the wall of the liquid-passage tapers upwardly and inwardly from the outer edgeof said shoulder to the inner edge of said top 8o floor, and hence the inner face of said liquidpassage is formed with an abrupt edge (approximately annular sharp edge) at the inner surrounding edge of said top Hoor, for reasons which will appear hereinafter.

The seal is effected bya cork or disk b, preferably im perforate and of such diameter as to pass freely into the liquid-passage to the annular ledge or shoulder d4, against the upper face of which said disk is adaptedto rest com- 9o pletely around the liquid-.passage and so as to form a liquid-tight joint or seal therewith when compressed and locked. 'lhis disk can be formed of any suitable and desirable material,l although as at present advised I usually employ suitably-prepared cork; but my invention is not so limited.

o is a locking plug or disk formed of thin sheet metal sufficiently ductile or pliable to permit the expansion hereinafter set forth Ioo and so that the cap after being expanded will remain in that condition to maintain the liquid-tight joint. The metal of the plug possesses such characteristics as to maintain the seal after being locked in the bottle-neck by expansion, yet is capable of easy extraction when the necessary pressure is applied in the proper direction, as hereinafter set forth. The plug is hollow and cup-shaped by a shallow central depression having a circular flat door or bottom of such external diameter'as to pass snugly through the liquid-passage at the abrupt inner edge of the said top floor. Said diameter of the central depression or lower end of the plug is greater than .the diam eter of the Vliquid-passage at the stop ledge or shoulder and is usually, although not necessarily, approximately the same as the diameter of the sealing cork or disk, on which it flatly rests in maintaining the seal and liquid-tight joint. The upper edge or end of the plug is formed with the outer surround ing flat flange c' of such external size or dianieter as to permit the same to enter the annular toprecess of'the bottle-neck. Before the plug has been applied to the bottle it is preferably cylindrical and of the same diameter from its lower end to the ange, as shown in Fig. .2, although the lower end of the same can be rounded, if desired, about as shown in Fig. 7.

It has been found exceedingly difficult and inconvenient to extract or remove the ductilemetal bottle-seals heretofore produced from the bottle. It has been necessary to have at hand peculiar tools in order to remove the metal disk or seal. It is an exceedingly difficult and inconvenientoperation for an in experienced person to remove such seals even with the peculiar tool provided for each particular device, in View of the rocking or lever movement necessary to tilt or twist the disk, plug, or cap in releasingit from the bottle. It is practically impossible to pull such plug stoppers directly outv from the end of the bottle; but in order to effect release it is necessary to tilt or rock the plug or disk upwardly or back from one edge or side with a twisting or lever action. I avoid these objections and generally follow the above-noted opening movement by employing a sealing plug, disk, or cup of any shape or form provided with a projecting lever-arm or extractor thumb-piece or projection suitably attached to or formed with the seal. The extractorlever or thumb-piece can be of any suitable form or construction and applied to any sealing disk or plug in any suitable manner or by any suitable means. A bottle-seal constructed with such an extractor can be easily removed by placing the thumb against the outer face of the lever or extractor arm and bracing the hand by placing several fingers on top of the seal and then pressing inwardly or inwardly and upwardly on the said arm, whereupon the seal will be broken. and the disk, cup, or plug tilted or rocked from the bottle-mouth by a lever action, the arm and plug usually moving together approximately as one lever. proximately rigid lever extractor-arm, projection, or th um b-piece d,approximately rigid with the plug and moving from the bottle with the plug in the extracting operation. This arm projects from the top edge of the plug to a point at the exterior of the bottleneck, where free access vcan be had thereto for the application of the necessary pressure to effect the extraction. In the specific example shown the arm-piece projects upwardly through a suitable opening formed'in the flange c' and is deflected laterally. Suitable means can be provided to rmlyax the arm to the plug in an approximately permanent or rigid manner. anism for this purpose I show the arm formed by a lateral central loop or deflection ina length of wire or rod of metal possessing the desired qualities. The two projecting ends c c are bent to form a ring-like portion which partially embraces the cylindrical plug Y just beneath the top ange thereof. These projecting portions or ends of the extractorarm can be secured in any manner to the plug, but usually are compressed thereon, so as to firmly grip the same, and are held in place against pulling therefrom during the extracting operation by the said top flange. For reasons which will be set forth hereinafter these wire ends or arms need not completely embrace the plug, but can leave a blank space between their ends and diametrically opposite the extractor-arm. However, I do not wish to limit the broad features of my invention to'such specific construction.

I provide the plug with an ap- As a suitable mech-Y reo Y Fig. 2 shows the sealingfdisk in positionon 1 the sealing-shoulder in the bottle-neck, with I the plug resting thereon and the flange of the Y Y plug above the top recess of the bottle-neck and the wire arms in said recess and a distance above the floor thereof. Through the medium of the proper tool the plug is then il forced downwardly until the said wirearins engage the door of said top recess, and the top flange of the plug is about flush with the up-V per edge of the bottle-neck. By this operation the sealing-disk is tightly coni pressed be;

tween the dat lower end of the plug and the saidsealing shoulder or ledge of the bottleneck,and the lower end of the plug is forced Y below the plane of said abrupt edge of the top floor, and while the pressure on the plug is Y tightly compressed against the sealing-shoulder of the bottle-neck. Advantages are also In this construction advan-V attained by having the expanded portion of the plug immediately below and in the direct line of the strain of the extractor lever-arm on the plug-as, for instance, in the specific example illustrated the shallow cylindrical portion of the plug to which the lever-arm is secured is also the portion of the plug which is expanded to lock the plug, and the distance between the attaching-wire ends of said arm and the expanded portion of the plug is very slight-viz., only the thickness of the abrupt edge of the tloor ofthe top recess around the bottle-mouth. By reason of this arrangement the plug is easily and quicklyextracted bythe necessary lateral and slightly-upward pressure on the extractor lever-arm, as the pull from the lever-arm is directly on the expanded portion of the plug, immediately under the junction between the'said arm and plug, and hence the initial tearing away or release of the expanded portion of the plug takes place under said arm, and as the side of the plug provided with the arm moves up the diametrically opposite side ot the plug is forced downwardly, and hence the expanded portion of the plug opposite the arm is withdrawn laterally from the undercut portion of the bottle-neck, and the plug is tilted or rocked from the bottle. In effect, the lock is broken as soon as the initial release of t-he expanded portion of the plug takes place under the extractor-arm, and the re mainder of the extracting operation is comparatively simple. I have found that material advantages are attained by so forming the portion of the plug diametrically opposite the extract-orarm as to permit downward movement thereof, whereby the plug during the extracting operation might be said to rock on an axis at a line intermediately between the lever extractor-arm and the diametrically opposite edge of the plug-say about on the ends of the wire projections from the said arm embracing the plug. By permitting this peculiar function it is only necessary to forcibly tear or pull the expanded portion of the plug immediately under the lever-arm from the undercut part of the bottle-neck, while the diametrically opposite expanded 'portion of Ythe plug can move inwardly or radially of the liquid-passage from the undercut portion, as partially illustrated in Fig. 10. To permit this downward movement of the portion of the plug opposite the arm, I have left a clear space between the top flange of the plug at such point by not extending the encircling wire completely around the plug, so that said portion of the plug can move downward and can collapse or double up, if necessary, although possibly this collapse or doubling of the plug will not always take place, as shown in Figs. 5 and l0. So far as I am now advised by experiments, it would seem that the peculiar advantages are attained by so constructing the plug as to cause the same to rock or tilt during the extracting operation on an axis at right angles to and intermediate the length of the diameter or plane including the extractorle ver-arm. It should be understood, however, that myinvention in this particular is not limited to the peculiar plug and impertorate sealing-disk herein shown, as the disk might be otherwise formed than imperforate and the plug might be otherwise formed. In the specific construction illustrated I attain advantages by employing the im perforate disk, as the liquid contents of the bottle are thereby kept from contact with the plug, and

a cheaper metal can be employed for the plug` than is necessary where a su rrounding washer only is employed and the liquid has free engagement with the plug. It is also obvious that my invention is not limited to the peculiar construction of bottle-neck shown nor to the peculiar construction of lever extractorarm and its attaching means.

I do not wish to limit my invention in all respects to the employment of a sealing medium, nor, if such be employed, to a sealing medium of any particular material.

It is evident that various changes and moditications might be resorted to in the forms, constructions, and arrangements described and shown without departing from thespirit and scope of my invention. Hence I do not wish to limit myself to the construction illus- Y trated.
