NON-REFILLABLE BOTTLE.

SPECIFICATION forming part of Letters Patent No. 709,031, dated September 16, 190B. Application filed January 2,1902. Serial No. 88.168. (No model.)

.To all whom t 712.61.34 concern:

Be it known that I, RALPH MCCORD, a citizen of the United States, residing at St. Louis, inthe State of Missouri, have invented certain new and useful Improvements in Non- Rellable Bottles; andl 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 make and use the same.

My invention relates to non-refillable bottles; and its object is to provide one which is simple, inexpensive, and efficient in its operation, wherein the parts comprising the stopper or guard are separate and independent of the bottle, but which may be inserted into the neck of the latter and permanently held therein to prevent liquid being introduced into the bottle after the original contents have.

been dispensed.

The invention consists in providing a stopper with a longitudinal eccentric truncated cylindrical chamber in which a ball-valve operates and which communicates with transverse apertures leading to the annular space between its periphery and the inner wall of the bottle-neck and means to lock the stopper in the said neck.

It further consists in the construction, come bination, and aggroupment of parts, as will be more fully described hereinafter and finally pointed outin the appended claims.

For a full understanding of the merits and advantages of my invention reference is to be had to the accompanying drawings, in which- Figure l is a side elevation of the stopper applied to a bottle, the bottle-neck being broken away and shown in vertical section. Fig. 2 is a Vertical section of the stopper detached. Fig. 3 is a bottom plan view of the same. Fig. 4 shows top and end views of the expansible lockingband. Fig. 5 is a side elevation of the stopper with the locking-band detached. Fig. 6 shows top, plan, and side elevational views of the valve-scat detached; and Fig. 7 isa top view of stopper.

Referring to the drawings, A designates the bottle-neck, having an internal annular groove B, which receives the expansible locking-band carried by the stopper C, aswill be more fully described hereinafter. The stopper C is provided with a longitudinal truncated cylinL drical. chamber D, (see Fig. 2,) formed ec centrically therein, and this chamber communicates along one of its sides with a segmental chamber E, the arched Wall of which is concentric with the periphery of the stopper. The cylindrical chamber C is intersected at its upper end by a transverse aperture F, and the segmental chamber is likewise intersected by a transverse aperture G opposite the aperture I-I. The chamber E and the apertures H and G serve as discharge-passages when the bottle is being emptied. The stopper is provided with an annular rib I and a flanged top J, beneath which there is formed on one side of the stopper a recess K. Prior to inserting the stopper into the bottle-neck an expansible locking-band L is inserted thereon beneath the annular flange J. This locking-band consists of a spring-band bent in substantially semicircular form, with its ends overlapping at the center of its straight side, as shown at L' in Fig. 4. 'The straight overlapping ends fit within the recess K when the locking-band is on the stopper, and its projecting portions may be collapsed to permit it4 to be inserted in the bottleneck; but it immediately expandswhen these projecting portions engage the annular groove B in the neck and lockrthe stopper in position, the annular flange J preventing the insertion of instruments to release the band,

` and therefore preventing thestopper from beingremovedafteritisonceinserted. Through the lower wall of the stopper an opening M is made, which extends a short distance above the bottom of the rib L, the purpose for which will presently be described. The bottom of the stopper is provided with a valve-seat N, which is made in the form of a cap and incloses the lower sides and bottom of the stopper. This valve-seat is provided with an eccentric opening O, the edges of which form a seat for the ball-valve P, playing in the chamber D. The sides of the cap N engage the sides of the stopper and cover a portion of the opening M, where it is indented, as at Q in Fig. 2, to hold the cap in place, and upon this cap a band of soft packing material R is placed to form a liquid-tight joint when the stopper is inserted in the bottle-neck, the rib I serving to hold the packing 'material in IOO place. The portion of the openingM which extends above the lower edge of the rib I is not covered by the packing and communicates with the chamber E to form an air-vent When the liquid is being poured from the bottle. This vent is shown at S in Fig. 2.

The Wall of the chamber D is provided with an obstruction T about midway of its ends to stop the ball-valve P in its upward course and prevent it from closing either of the apertures G or I-I. The uppermost position of the ball-valve is shown in dotted lines in Fig. 2.

When the parts of the stopper are assembled together, as shown in Fig. 2, it is ready to be inserted in the bottle-neck, and when the expansible band L coincides With the annular groove B the stopper is held in place. Upon tilting the bottle to pour the contents the ball-valve P will be unseated from the opening O and Will stop at the obstruction 'F in the Wall of the chamber D. The liquid can now flow through the opening O into the chamber E and discharge through the apertures G and H into the annular space U around the stopper and out through the passage between the flattened face of the annular ange and the bottle-neck. The annular flange does not fit snug against the wall of the bottle at any point, so that air is permitted to enterinto the space U and through the vent S. After the contents have been poured from the bottle the ball will again assumeits position to close the opening O, and as no liquid can pass through this opening when the ball is l`seated therein and nothing can pass between the packing R the bottle is rendered non-rellable.

Having thus described my invention, what I claim is- 1. In a non-refillable bottle, the combination with the bottle-neck having an internal annular groove formed therein, of a stopper having longitudinal communicating chan1- bers, transverse apertures leading from said chambers, a detachable valve-seat, a valve mounted in one of the chambers, and an eX- pansible locking-band to hold the stopper in the bottle, substantially as specied.

2. In a non-reiillable bottle, the combination with a bottle-neck having an annular groove, of a stopper carrying an expansible locking-band to engage the annular groove, said stopper having longitudinal communieating chambers and transverse discharge-apertures, a valve playing in one of the chambers, means to limit the movement of the valve, a detachable valve-seat, and means to permit a free circulation of air around and into the stopper When the contents are being pouredfrom the bottle.

3. In a non-refillable bottle, the combination with the bottle-neck having an annular groove formed therein, of a stopper provided With a longitudinal eccentric, truncated, cylindrical chamber, and a ball-valve operating in the said chamber, a longitudinal segmental chamber communicating with the cylindrical chamber, and having an air-vent leading thereto, transverse discharge-apertures leading from each of the chambers, a detachable valve-seat, and means to engage the annular groove to hold the stopper in a bottle-neck.

4. As an article of manufacture, the combination with the bottle-neck having an aunular groove, of a stopper having an annular flange at its top provided With a flattened face, a recess beneath the annular iiange, longitudinal chambers formed in the stopper and communicating with transverse dischargaapertures, a valve in one of the chambers, a valve-seat fitted on the lower end of the stopper, and a packing encircling the side of said valve-seat, means to prevent displacement of the valve-seat and the packing, and an eX- pansible locking-band bent in semicircular form having overlapping ends which lit within the recess beneath the annular Hanger, said locking-band adapted to expand and engage the annular groove in the bottle-neck, substantially as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.

RALPH MCCORD.
