Specification of Letters Patent.

Application filed. December 11, 1912.

To all whom it may concern Be it known that I, MAX I. Sonnet, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented new and useful Improvements in Non-Refillable Bottles, of which the following is a specification The object of the present invention is to provide a cheap, easily constructed, and effective non-refillable bottle.

In the accompanying drawing, Figure 1 is a vertical section of the upper portion of a bottle equipped with my invention; Fig. 2 is a horizontal section on the line 2--2 of Fig. 1; Fig. 3 is a side view of the retainer removed; Fig. 1 is a side view of the valve removed.

Referring to the drawing, 1 indicates the neck of a bottle, the inner surface of which has a downwardly tapering conical seat 2. In said seat can fit snugly a conical annular buoyant valve 3 comprising a thin shell closed at, the bottom, and a cork float t secured therein. A retainer 6 of tubular form is secured within said neck by pressing a bead 7 therefrom and into a groove 8 in the inner surface of the neck of the bottle. The upper or outer end 9 of said retainer is also swaged to fit snugly around the top of the neck of the bottle.

The inner surface of the neck of the bottle, between said valve seat 2 and groove 8, is preferably cylindrical, and the retainer 6, below said groove, is conical, so that an an- .nular space is left between the retainer and the inner surface of the neck, in which the shell of the valve is received when the bottle is inverted. The lower end of said retainer is closed, as shown at 11., and in the conical wall of the retainer, immediately above said closed end, there are formed rectangular apertures 12, four being here shown. Centrally riveted to the closed end of the retainer, as shown at 13, is a circular base 141, from which extend obliquely upward, to the conical wall of the retainer, wings 16, corresponding in number to that of the apertures 12. Upon the upper edges of said wings, resting against said conical wall of the retainer, is placed a circular perforated disk 17, and the conical wall of the retainer is then swaged inwardly over the edge of the disk, to retain said disk in place.

Patented Sept. 23, 1913.

Serial No. 736,136.

The wings are so arranged that they cover and protect the holes in the retainer, even if a wire or other device should be introduced through the perforated disk.

One of the conditions most di'llicult to be fulfilled in providing a non-refillable bottle is the provision of a suliiciently large conduit for the flow of the liquid when dispensing from the bottle to prevent the backward suction caused by the inability of the air to enter the bottle to replace the liquid dispensed therefrom. To avoid this dilliculty I provide the conical wall of the valve 3 with large openings 5, said openings occupying, in fact, the greater part of the circumference of the valve at their zone, said openings being so located in said wall, that when, by inverting the bottle, the upper surface of the float i in the valve impinges upon the end 11 of the retainer, the open ings 5 are substantially on the same level as the apertures '12 in the retainer. Therefore, in pouring from the bottle, the liquid can flow very freely and rapidly through said openings 5 and apertures 12.

T am aware that it has been proposed to provide a frusto-(umical valve to prevent refilling, but all such valves, so far as I am aware, have been formed without apertures for the liquid in their conical walls. Consequently, when pouring, it is necessary for the liquid to flow past the larger end of said valve. It is then invariably found that the suction, produced by the withdrawal of the liquid without its place being refilled by air, causes the valve to be sucked back to its seat, from which it is then practically impossible to dislodge it. This action is assisted by the inward llow of the liquid past the lower or larger end of the conical valve, the pressure attendant on which flow tends to raise the valve, and thus to contract the passage for the air into the interior of the bottle to supply the place of the liquid which has passed out, and thus to cause. the valve to seat itself firmly on its seat. This I avoid by providing the openings 5 in the conical wall of the valve, through which the liquid can llow to the apertures 12, and, in so flowing through said apertures, has no tendency, as above explained, to raise the valve to its seat, but tends to move the valve away from its seat.

toward, said valve, and spaced from eel; to pernnt sa d valve to passbetween the retainer and the neck, said retainer having apertures in the sides, a protector within; the retainer having wings covering said apertures, the valve :being formed with apertures arranged to be on the same level,

wl'i'e 'the bottle is inverted, as the apertures in the retainer, and substantially coextensive therewith, and a perforated disk secured 15 within the retainer and preventing aoess to said wings.
