NO-N-REFILLABLE BOTTLE.

Specification of Letters Patent.

Patented Apr. 7, 1914.

Application filed April 9, 1913. Serial 310 759349.

To all whom it may concern:

Be it known that I, FRED H. CHAPMAN, a citizen of the United States, and a resident of Winchester, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Non-Refillable Bottles, of which the following is a specification.

This invention has for its object to provide a non-refillable bottle having a substantially cylindrical. neck of simple and common form, and simple accessories adapted to permit free pouring from the bottle when the latter is inverted, and to prevent liquid from being forced into the bottle by fraudulent methods commonly employed when the bottle is held horizontally or approximately so, the nature of said accessories being such that all the parts exposed to liquid may be made of glass or like non-corrosive material.

The invention consists in the improvements which I will now proceed to describe and claim.

Of the accompanying drawingr-Figture,

1 represents a sectional view of the neck portion of a non-refillable bottle embodying my invention, the bottle being upright. Fig. 2 represents a similar view, the bottle being held horizontally. Fig. 3 represents a similar view showing the bottle inverted. Fig. 1 represents a view of the outer end of the baffle plug. Fig. 5 represents a side view of the battle plug. Fig. 6 represents a view of the inner end of the baffle plug. Fig. 7 represents a plan view of the locking ring shown by Figs. 1, 2 and 3.

The same reference characters indicate the same parts in all the figures.

In the drawings :12 represents a cylindrical bottle neck of ordinary form, provided at its inner end portion with a valve seat 13 which is preferably tapered, the angle of the seat relatively to the longitudinal axis of the neck being preferably as shown by Figs. 1, 2 and 3, the seat being adapted to be closed by a semispherical valve face occupying different positions, as shown by Figs. 1 and 2, and to permit a free outward flow of liquid when the bottle is inverted, as shown by Fig. 3. The valve seat may be integral with the neck or may be made as a separate piece secured to the neck as shown by Fig. 3.

1 1 representsa baffle plug firmly secured in the neck above the valve seat and spaced therefrom, the plug being adapted to form, with the neck, a tortuous passage for the outflow of liquid, and to prevent a flexible wire or other tapering device from entering the space bet-ween the plug and valve seat.

In the embodiment of the invention here shown, the baiiie plug has an enlarged outer end portion secured to the neck by a looking ring 15 or otherwise, a reduced inner end portion separated from the interior of the neck by an annular passage 16, a central passage 17 extending through the enlarged portion into but not through the inner portion and ports 18 connecting the passages 16 and 17. The reduced portion is prefer ably provided with lugs 19 which bear 011 the interior of the neck, and steady the inner end of the plug.

An important structural feature of the baflie plug 14: is an inwardly facing annular stop shoulder 20 which is concentric with the inner surface of the neck and is the wall of a circular recess 21 formed in the inner end of the plug, said shoulder being of con siderably smaller diameter than the neck, so that liquid is free to flow outwardly between it and the neck.

22 represents a valve having a semispherical acting face, adapted to bear closely on the seat 13 when the valve is in different positions as shown by Figs. 1 and 2. The valve is provided with an outwardly pro-- jecting weighted stem 23 which is rigidly attached to the valve or formed integral therewith, said stem having an enlarged outerend which is heavier than the valve, and is provided with a crowning end face 24. preferably of the conical form shown by Figs. 1, 2 and 3. The apex or highest part of said face projects into the recess 21 and coincides with the longitudinal center of the stem 23, the distance between said apex and the acting face of the valve being such that the apex is prevented by the valve seat from leaving the recess 21. The crowning face 2 1 is, however, movable in different directions in said recess, so that the valve and stem are adapted to be moved by gravitation from the position shown by Fig. 1 to that shown by Fig. 3, to open the valve, and from the position shown by Fig. 1 to that shown by Fig. 2, to permit the crowning face 24 to bear at one side of its apex against the annular stop shoulder 20 when the bottle is held horizontally. The inclination of the face 24L is such that whenever it bears on the stop shoulder it is caused by the weight of the outer end of the stem to act as a wedge, holding the valve tightly closed. Said wedge cannot be displaced sufficiently to permit the opening of the valve by any of the usual manipulations employed to beat a supposedly non-refillable bottle.

The locking ring 15 may be made of wood, metal or other suitable material and is cut at one side as shown by Fig. 7. It is sufliciently resilient to normally expand or spring outwardly. When the baffle plug is first inserted in the neck, the ring 15 is contracted by the neck into a groove 25 in the plug, until it reaches and springs into a groove 26 in the neck, thus locking the plug to the neck at a predetermined distance from the valve seat.

The parts may be assembled by holding the bottle horizontally, placing the valve 22 on its'seat with the margin of the crowning face 24 resting on the lower side of the neck, and then pressing the plug inwardly until it is locked by the ring 15. The inward movement of the plug to its predetermined position causes the annular shoulder 20 to bear on the crowning end face 24; at a point at one side of and below its apex, and raise the stem out of contact with the neck as shown'by Fig. 2, the apex of the end face being confined by the annular stop 20 and the valve seat 13 against removal from the recess 21.

What I claim and desire to secure by Letters Patent is A non-refillable bottle having a substantially cylindrical neck, a valve seat and a baflie outlet plug spaced apart from each other in said neck, the inner. end of the plug being provided with an annular in wardly facing stop shoulder concentric with and separated from the wall of the neck and surrounding a recess in the plug, and a valve having a semispherical acting face and an integral weighted stem projecting outwardly from said face, and provided at its outer end with an enlarged integral crowning face which projects into said recess and having its end surface inclined with respect to said stop shoulder, said crowning face havin a wedging action with the annular stop shoulder to prevent endwise movement of the valve and stem with respect to the seat until the bottle is tilted beyond a horizontal position. 7

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