GEORGrE A. PORTER, OF BOSTON, MASSACHUSETTS, ASSIGNOR TO INVINCIBLE STOPPER COMPANY, OF BOSTON, MASSACHUSETTS, A CORPORATION OF MASSACHUSETTS.

NON-REFILLABLE BOTTLE.

To all whom t may concern.'

Be it known that I, GEORGE A. PORTER, a citizen of the United States, and a resident of Boston, in the county of Suffolk and Commonwealth of lVIassachusetts, have invented certain new and useful Improvements inNon-Refillable Bottles, of which the following is a full,`clear, and exact specification.

The object of this invention is the construction of an improved device disposed for being secured within the neck of a bottle to prevent the latters being refilled, the objects sought being bothsimplicity of parts, economy in manufacture and certainty in operation.

Referring to the drawings forming part of this specification, Figure 1 is a vertical central section of the upper part of a bottle containing my improved device. Fig. 2 is a side elevation of said device, but with the members composing it slightly separated. Fig. 3 is a longitudinal section of the device and bottle showing how the device automatically closes when in a substantially horizontal position. Fig. el is a plan view of one of the members composing the device. Fig. 5 isl a longitudinal section of the device and bottle neck showing the same inverted.

The reference numeral 1 designates the neck of a bottle of substantially usual form, practically the only difference over bottles now in use consisting of a shoulder, or projections, 2 within the neck near its juncture with the body of the bottle.

The bottle stopping device comprises five parts, three of which compose the case or stationary parts, and the other two being the movable members. The latter members consist of the valve and the valve-closer.

Said stationary parts consist of three cylindrical members or sections, the lowermost one of which is numbered 3 and carries the valve opening and seat 4. The intermediate member or section 5 is an inverted cup having its walls internally oblique, at an angle of preferably about thirty degrees, with several vertical holes or channels 6 opening through the walls to the upper' surface 7.

The uppermost member or section 9 is formed with a mouth 10 for receiving a cork or like means of closure, the bottom 11 thereof having a centrally located pouring hole 12 through it. This hole is made slnall Specification of Letters Patent.

enough in diameter to cause the bottom 1l to act as a shield for preventing the introduction of a wire or like instrumentality through the hole 12 and one of the channels 6, and thence down into engagement with the valve.

Said three sections are formed with mutually engaging seats and flanges 13 which are preferably cemented together before the same are put into place, and a supply of cement is also applied between the same and the interior of the bottle neck, particularly between the two ribs 11 on the section 9. This not only fastens the device in place, but prevents leakage between the same and the interior of the neck.

Through the hole or valve opening l projects the stem 1G of a loose valve 15, the latter being designed to rest upon the valve seat et and close the opening against the admission of any liquid to the bottle. The stem is a truncated cone in general shape, but with its lateral surface concaved, its largest diameter loosely fitting the opening a. Above the valve and resting thereon when the bottle is not in an inverted position, is a ball 17 of some comparatively heavy material, as metal, glass or the like, and serving to insure the liquid-tightness of the valves seating.

lVhen the bottle is turned upon its side, the ball rests upon the inclined surface S and rolls against the valve 15 with sufficient pressure to hold the latter tightagainst the seat l. In practice, it is found that the body of the bottle can be elevated until its lowermost point is at the level of the valve opening, and the ball will still act against the valve hard enough to keep it closed.

lVhen the bottle has been tipped until the ball 17 leaves the valve, even until the bottle is entirely upside down, the ball cannot close the channels G and in any perceptible Inanner interfere with the out-flow of the bottles contents. This is clearly evident in Fig. 5.

As shown in the drawings, the upper surface of the section 5 close beside its flange 13 and comprising the areal penetrated by the channels 6, is outwardly depressed or made flatly conical. The object of this is to further prevent the introduction of a Wire through the hole 12 and one of the conduits or channels 6, and thence down to a point `where it might engage and hold the valve in an open position. With a suitably flexible Wire, the outermost surface of one of the channels might be met by the end of' the wireintroduced'atan angle through the hole l2, and by pressure the Wire be pushed` down through such channel; but, by charnfering said area as described, the Wire-end cannot engage the outermost surface of a channel, butl will meet the flange 13v and the slight shoulder or ledge between it and aI channel. This renders it practically impossibleA to, Work a Wire down into engagement with the, valve.

The valve itself is composed of a comparatively light material, in order that, in CaSe the vacuum method of filling is attempted, the inrush of the liquid will loat the valve up into contact with the valve-seat and thereby eectually prevent further reception of the fluid.

What I claim is:

A device for rendering bottles non-refilla'ble, comprising a chambered member secured in the neck of the bottle for which it is designed and having a central opening communicating with the bottle, a gravity valve forA closingy said opening, a member spaced from.. said ichamfloered member nearer the mouth of the bottle and having a central opening, the roof of said chambered member being centrally flat and transverse to the axis of' the bottle neck, an annular space about said. flat. spacel 'approximating a frustum of a cone, anda plurality of holes passing through saidannular spaceparallelwith axis.V of7 the bottle neck intov the space Within thechambered membensaid annular space beingy slightly prolongedbeyond the circle of saidv holes, Wherebyfa Wire is hindered from entering said holes fromA the central opening above.

In testimony that .I claim the foregoing inventiom Il have hereunto set my hand this 7th. day, of October, 1915,
