NoN-nnr LLABLE BOTTLE.

Patented Feb. 22, 1916.

To all whom it may concern:

Be it known that I, ELI E. GREGORY, a citizen of the United States, residing at Central City, in the county of Muhlenberg and State of Kentucky, have invented certain new and useful Improvements in Non-Refillable Bottles, of which the following is a specification,reference being had to the accompanying drawings.

This invention relates to non-refillable bottles and similar receptacles and has for its primary object to provide a bottle which i the contents of the bottle may provided with a cannot be fraudulently refilled without detection by the purchaser.

The invention has for an additional object to provide improved means for tightly sealing or closing the bottle, tion of the bottle having an section so that the same may the neck porbe readily broken ofi by the application of heat and access had to the seal or stopper whereby be decanted.

It is an additional object of my invention to produce a device of the above character which is simple and inexpensive in its construction and highly serviceable and reliable in practical use.

With the above and as will become apparent as the description proceeds, the invention consists in certain constructions, combinations and arrangements of the parts that I shall hereinafter fully describe and claim.

For a full understanding of the inven tion, reference isto be had to the following description and accompanying drawings, in

which- Figure 1 is a side elevation of the upper portion of a bottle which is provided with my invention; Fig. 2 is a vertical section; Fig. 3 is a detail perspective view showing the upper end of the bottle neck broken ofi and the stopper exposed; Fig. 4 is a section taken on the line 1-4 of Fig. 2; and Fig. 5 is a vertical section'similar to Fig. 2, illustrating a slightly modified form of the invention.-

Referring in detail to the drawing 5 designates the body of the bottle or other container and '6 the neck thereof. This bottle neck at a point intermediate of its ends is deep exterior annular is provided easily frangible other objects in view groove 7 and also with a relatively shallow i the wall of the neck 6 is formed with an inwardly projecting annular enlargement 10 for a purpose to be later explained.

At the mouth of the bottle neck the same with an inwardly inclined or sloping end face 11 at the base of which the annular groove or seat 12 is formed. 13 designates the stopper which is formed of cork or other compressible material and is of approximately the same diameter as the interior diameter of the bottle neck. This stopper is adapted to be forced into the neck of the bottle and beyond the inwardly pro- ]ecting annular portion 10 of the wall thereof whereby the cork will be tightly compressed and extraction of the cork efl'ectively prevented. The cork stopper 13 is provided with a central longitudinal opening or bore to receive the stem 14 of a glass plug. Upon one end of the stem the circular head 15 is formed having the concave outer face 16. It will be understood that the stopper and glass plug are first assembled and then inserted together into the neck of the bottle. The compressing action of the inward projection 10 on the bottle neck against the cork stopper also creates a binding or tight frictional pressure of the cork body upon the glass stem 14 so as to securely hold the plug in place within said stopper. As an additional means of security I provide a sheet metal disk 17 which is of slightly greater diameter than the interior diameter of the bottle neck and is adapted to be forced into the mouth of the bottle upon the beveled or inclined wall 11 thereof. As said sheet metal disk is forced inwardly, it is gradually bent or curved until the edge of the disk is disposed opposite the annular seat or groove 12. Owing to the inherent resiliency of the sheet metal, the disk will attempt to assume its normal shape and the edge portions thereof will spring outwardly into the groove or seat 12. The disk 17 will, however, still be slightly curved and will engage upon the concave face 16 of the head 15 on the glass plug. It willbe observed that this head 15 on the plug is approximately equivalent in diameter to the interior diameter'of the bottle neck and entirely covers the end of the cork stopper so that the stopper cannot be mutilated and particles thereof withdrawn by drilling through the sheet metal disk 17.

For the purpose of readily breaking the bottle neck at the reduced wall section 9 thereof, I preferably arrange in the exterior groove 7, a waxed taper indicated at 18. Assuming that the parts have been arranged in the manner shown in Fig. 2 of the drawing and the bottle tightly sealed after being filled, when the purchaser desires to decant the contents thereof, it is only necessary to ignite this waxed tapen The reduced section 9 of the bottle neck being thus highly heated, finally breaks. This break in the bottle neck will leave an even sharp edge on the lower section of the neck, and as the cork stopper 13 projects outwardly .from the which part will of course be removed with .and approximately in juncture of the upper end of the tapering the broken off end section of the bottle neck. The glass plug may be readily removed fromthe cork stopper by simply inserting a knife or other instrument between the head thereof and the end of the cork and then forcing or pulling out upon the plug. The cork stopper at all times remains in place and the bottle may be very securely sealed after use by reinserting the stem of the glass plug into the bore of the cork stopper.

In Fig. 5 of the drawing I have shown a slightly modified form of the device where in the bottle neck 6 is provided at some distance from its upper end or mouth with the downwardly tapering bore section 19 whereby an annular shoulder 20 is produced in the bottle neck. This shoulder may either be square or at right angles to theaxis of the bottle neck or disposed at an inclination with respect thereto. In the periphery of the bottle neck and upon the exterior thereof line with the pointof section 19 of the bore with the wall of the bottle neck, the annular groove21 is formed therein to reduce or weaken said bottle neck. While in this form of the device I have illustrated only an exterior groove on the bottle neck, it will be understood that the same may be provided with an interior groove as well, as in the construction previously referred to. In this modified construction the mouth ofthe bottle neck is not manufacturer may if This cut connection with the refil ab e bot le w formed with the tapering or flared end; wall 11, as the use of'the metal sealing disk is eliminated and the compressing action upon that when the cork and the stopper are inserted into the bottle neck, the contracted bore section .19 compresses the corkqtightly upon the. glass stem as .the cork is pressed inwardly, said cork shoulder 20as clearly shown inthe drawing. Thus. thev removal of th'eccork is effectively prevented, and said cork stopper in turn operates by its gripping action upon the glass expanding under, the;

From the foregoing description taken in accompanying drawing, the construction, manner of operation and certain advantages be fully and clearly understood.

The several parts of the device being of exceedingly simple form, it is manifest that of my improved nonthe invention asa whole can beproduced 3131;,

The nvention provides a very effective means for preventing the unauthorized ,re-

filling of bottlesor other receptacles wherebypurchasers might bedeceived into the be-.;;

It is obvious that the invention maybe manufactured in various sizes in' accordance with the size cork of the bottle or receptacle: 1.

to which it is applied.

The several parts may also be variously modified in form and proportion andI therefore reserve the privilege of resorting to all such legitimate changes which may be,

fairly embodied withinthe spirit and scope of the invention as claimed.
