NON-REFILLABLE BOTTLE.

SPECIFICATION forming part of Letters Patent No. 748,885, dated. January 5, 1904.

Application filed October 17, 1963.

To all whom it may concern:v

Be it known that I, MAYER REINFELD, a citizen of the UnitedStates, residing at St. Louis, State of Missouri, have invented certain new and useful Improvements in Non-Refillable Bottles, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention has relation to improvements in non-refillable bottles; and it consists in the novel construction of bottle more fully set forth in the specification, and pointed out in the claim.

In the drawings, Figure 1 is a middle vertical section of the bottle, partly in elevation, showing the parts in their normal position. Fig. 2 is an inverted view of the bot tle, showing the valve open for the free ef- Fig. 3 is a horizontal section on line 3 3 of Fig. 1, and Fig. 4 is a sectional detail of the plug closing the hole in the bottom of the bottle.

The object of my invention is to construct a bottle which it will be practically impossible to refill without detection after being once drained of its contents, the bottle in the first instance being filled through an opening in the bottom, which is subsequently closed by a plug incapable under ordinary circumstances of removal by parties handling the bottle.

In detail the invention may be described as follows:

Referring to the drawings, B is the body of the bottle, and N the neck thereof, the mouth M of the latter being closed by a cork G in the usual way. Below the mouth M is formed an enlarged chamber 1 for the free play of a (preferably) conical valve 2, which when in its closed position rests against an annular ledge or seat 3, formed in the neck, the valve being provided with a depending stem 4, which is secured to the middle portion of a limiting head or bar 5. The latter is of a length as to engage the wall of the base of the neck when the. bottle is inverted, the points of engagement determining the distance to which the valve 2 may drop from its seat for the pouring position of the bottle. For the inverted position of the bottle Serial No. 177,461. on, model.)

the liquid contents flows around the head 5, through the neck, past the valve, and out .through the mouth of the bottle, as indicated out sleeve 8, terminating in a conical head 9.

The end of the stem 7 is subsequently expanded or burred over the head 9, when the plug is completed. In insertingthe plug into the opening of the bottom the head 9 becomes compressed sufficiently to pass therethrough and when forced fully through the base of the head laps over the walls of the opening, as best seen in Fig. l. The sleeve 8 fills the opening, and the disk 6 is received by a depression formed in the bottom of the bottle and of sufficient depth to bring the outer face of the disk flush with the surface of the bottom, whereby the plug will be permanently safe against any possibility of being gripped and withdrawn after once inserted. Of course the filling of the bottle is accomplished after the insertion of the outer cork C.

In practice the shank 8 of the rubber head 9 may beiprovided with a layer of suitable cement-or adhesive 10, which will set and harden and insure a perfectly liquid-tight joint at that point.

I do not wish to be limited to the precise details of construction for the several parts, as these may be varied without departing either from the spirit or nature of my invention.

Having described my invention, what I claim is In a non-refillable bottle having a body portion and a neck, a valve permitting the discharge of its contents through the neck for an inverted position of the bottle, the mouth of the bottle being adapted to be closed for such inverted position for filling purposes, the bottom being provided with a suitable opening, a depression surrounding said opening, and a plug having a terminaldisk adapted to be received by said depression and a resilient head adapted to be forced through 5 the opening, the base of the head subsequently lapping over said opening and efiecting a tight joint, substantially as set forth.

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

MAYER REINFELD.
