NONREFILLABLE BOTTLE Louis Schaffert, Highland, N. Y., assignor of twothirds to Evelyn A. Schaffert, Highland, N. Y.

Application January 26, 1934, Serial No. 708,453

1 Claim. (Cl. 215421) v This invention relates to non-rellable bottles and has for an object to provide an improved construction which is simple and yet effective,l

the structure being such that the fluid in the bottle may freely flow therefrom when the bottle is inverted or partly inverted.

Another object of the present invention is to provide a construction whereby bottles of well known make may be converted into non-refillable bottles by the addition of a non-reflllable stopper structure.

A further object, more specically, is to provide in a non-reiillable bottle a stopper structure which includes means to be secured to the neck of the bottle and a loosely mounted valve adapted to be unseated by gravity and the downward iiow of the liquid, and to be reseated by gravity or the inflowing of liquid, whereby inflowing liquid cannot enter the bottle.

In the accompanying drawing- Figure 1 is a view partly in elevation and. partly in section of a bottle and closure disclosing an embodiment of the invention;

Figure 2 is a transverse sectional view through Figure lon the line 2 2;

Figure 3 is a transverse sectional view through Figure 1 on the line 3 3;

Figure 4 is a view similar to Figure 1, but showing the bottle inverted to a large extent.

Referring to the accompanying drawing by numerals, 1 indicates an ordinary bottle body having a neck 2 which is the ordinary straight neck. The bore of this neck may be smooth interiorly but, as shown, there is provided an annular ange 3, which flange may or may not be used as desired. Arranged within the neck 2 is a non-rellab-le stopper structure 4 which rests on the ange 3, though if this flange is eliminated, the stopper structure will depend solely on the cement 5 to be held in place.

The cement 5 is ordinarily ample to hold the stopper 4 in place. It will be understood that when the device is to be used the bottle is flrst filled with the desired liquid and then the stopper or closure 4 inserted with the desired amount of cement 5. After this has been done an auxiliary stopper 6 is inserted, said auxiliary stopper being of any desired kind as, for instance, an ordinary cork stopper. This is necessary in order that when the bottle is inverted none of the contents will be discharged therefrom. However, when the contents of the bottle are to be discharged, the auxiliary stopper 6 is removed and the bottle inverted or partly inverted, as shown iro-Figure 4. The liquid will then readily ow from the bottle.

The stopper 4 presents a structure whereby the bottle cannot be relled. This structure may be made in several parts but, as shown, it is provided with an upper section '7 and a lower section 8, the respective sections being preferably made from glass or suitable vitreous material. When the iiange 3 is used section 8 rests thereon, said section having a suitable aperture 9 merging into adcurved valve seat 10 adapted to receive the valve member 1l which is cup-shaped except for the flange l2 which radiates from the upper edge, said flange having a number of notches 13. As illustrated in Figure 1 it will be clearly evident that the valve member ll'will rest upon the seat 10 by the action of gravity and also by the action of any liquid .which may attempt to force its way into the bottle. The upper section 7 is provided with a passageway 14 leading into a transverse passageway 15, which in turn has a passageway 16 merging therein at a point offset from the passageway 14, whereby a wire or other instrument cannot be inserted so as to engage or in any way manipulate the valve l1. If anything should be inserted to manipulate valve 11 the only result would be that the valve would be pressed more firmly against its seat.

It will be noted from Fig. 1 that there is provided an annular depending flange 17 at the lower part of section '7 which coacts with section 8 to produce a chamber 18 in which the flange 12 moves up and down, and also in which part of the valve member 11 moves up and down. Section 7 is also provided with a rounded central projection 19, the curve being substantially the same as the inner curve of the valve 11. A number of protuberances 20 extend from the projection 19, said protuberances spacing the valve 11 from the projection 19 when the parts are inverted, as shown Ain Fig. 4. This will permit the liquid to iiow around the bottom surface of the valve member and then between the valve member and the section 7 to the' passageway 16, from which it readily passes out of the bottle. It will be evident that the chamber 18 can be of any desired size and also the protuberances 20 can be of any length so as to provide the desired flow of liquid from the bottle. This tortuous passageway will permit the iiud to freely ow but acts to prevent any fluid from flowing back into the bottle, as the valve member'll is suiiiciently small to be floated back in place in case it was attempted to insert liquid while the bottle was upside down. The valve 11 may be made from thin glass or other material without departing from the spirit of the invention.

I claim:-

A non-rellable bottle, comprising a bottle member having a neck with a straight bore and an inwardly extending flange at the inner end of the bore, a closure structure tted into said bore and resting on said ange, and a cement layer for permanently securing said closure structure to said neck, said closure structure including a top section, a bottom section, and a movable valve member arranged between the top and bottom sections, said top section having a tortuous passageway therein terminating centrally at theV bottom of the top section, a ange at the periphery extending downwardly from; the bottom of the top section and resting on said bottom section, and a centrally rounded portion projecting downwardly when the device is inupright position, said bottom section being provided with a central aperture, said bottom section extending inwardly beyond said iiange of the top section so that there is provided a chamber between the top and bottom sections with said central rounded portion projecting into the chamber, a movable cup-shaped valve loosely positioned in said chamber and resting on said bottom section and positioned to normally close the aperture therein, said cup-shaped valve having a concave part facing upwardly and said central rounded portion of the top section projecting therein, but Anormally out of contact therewith, said cup- Vshaped valve having notched radiating iianges for holding said Valve member substantially central of said top section, and means carried by said Vcentral rounded projecting portion of the top section for preventing said valve from closing said tortuous passageway when the bottle is inverted.
