STOPPER FOR NONREFILLABLE BOTTLES im W muli.

ATTORNEYS Patented Apr. 20, 1937 UNITED STATES PATENT `OFFICE Claims.

'Ihis invention relates to non-rellable bottles and has for an object, the provision of a stop` per which can be made entirely from metallic stampings and which is provided with a tor- 5 tuous path that prevents the insertion of a tool or other foreign object into the neck of the bottle for the purpose of unseating the valve to refill the bottle.

Referring now to the drawings, Fig. 1 is a side elevation of a portion of a bottle embodying my invention; Fig. 2 is a section on an enlarged scale taken on the lines 2-2 in Fig. 1; Figs. 3, 4 and 5 are sections taken on the correspondingly numbered lines in Fig. 2; Fig. 6 is a sectional view of a portion of a bottle made in accordance with the construction shown in Fig. 2,

and illustrating the poiu'ing position; Fig. 7

is a side elevation of a portion of a bottle showing a modification of my invention; Fig. 8 is a sectional View on an enlarged scale taken on the line 8-8 in Fig. '7; Fig. 9 is a side elevation of a portion of a bottle embodying another modiiication; Fig. 10 is another section taken on an enlarged scale on the lines III-I0 in Fig. 9, and

Figs. 11, 12 and 13, are sections taken on the correspondingly numbered lines in Fig. 10.

Referring now to the illustration in Figs. 1 to 6 inclusive, Il) designates a bottle, the neck of which has a flanged portion II adjacent the top thereof and a threaded portion I2 which is disposed beneath the flanged portion. The stopper construction comprises a seat I5, which is disposed on the bottom of a cup-shaped casing I6 that fits snugly against the inner wall of the bottle. Within the casing there is positioned a valve I'I that is shown as an inverted cup-shaped member that has three arms I8, which bear lightly against the inner wall of the casing and provide a guide for the valve. Normally, the valve is held against its seat by gravity, but is moved away from the seat when the bottle is tipped for pouring, as is illustrated in Fig. 6. To provide a tortuous passageway between the valve casing I6 and the top of the bottle, I have shown a plurality of interconnected members and 2| which connect the casing to a top piece 22. The member 2l! is annular in shape and is provided with spaced arms 25, which extend from the inner periphery of the annulus. These arms are attached, such as by a swaging operation, to the member 2I which in turn is cupshaped and which has spaced arms that are attached to the member 22; the attachment being made preferably by swaglng the ends of 55 arms 26 onto the member 22. The top piece 22 is lprovided with a skirt 3i] which extends downwardly into the member 2| but which is spaced from the walls thereof and terminates short of the bottom thereof. 'Ihe top piece is also provided with a laterally extending flange 3l which is spun or otherwise forced downwardly at its outer periphery and crimped, as at 32, behind the flange II. A washer 33 is interposed between the bottle and top piece to make a fluid tight joint therebetween, while a cap 34 is threaded onto the bottle for sealing it.

When the bottle is open and tipped to a pouring position, liquid fiows in the paths indicated by the arrows in Fig. 6. In such illustration, liquid ows through anI opening 35 past the valve I'I, into the casing I6 and thence through the opening 36 in the annular member 20, and between the arms 25 into the space that is exterior of the member 2|. From such space, part of the liquid flows between the arms 26 into the cup shaped member 2| and thence through the skirt 30 and out of the bottle. Another part flows through openings 31 which are formed in the bottom of the top piece 22, although the latter openings are relatively small and are intended primarily for drainingv any residue that normally would be entrapped by the skirt 3B. They are formed by striking upwardly a small portion of the part 22 from the bottom wall thereof, as is shown particularly in Figs. 2 and 6.

The tortuous passageway which is formed by the members 2U and 2I eliminates the possibility of unseating the valve, by means of a wire, or other tool, that may be inserted through the open end of the bottle. Furthermore, the shape of the valve I'I prevents refilling, for the weight of the liquid in the casing I6 would hold the valve onto its seat.

A modication of the invention is shown in Figs. 7 and 8, wherein the bottle is provided with a flange 40, but is not provided with any threaded portion to which the cap may be attached. Accordingly, in such case, instead of ilanging the top piece laterally and downwardly, as is shown in Fig. 2, I extend it upwardly in the form of a cylinder, and provide an inturned flange 4I adjacent the top thereof. The part 22 is then anchored to the bottle by a separate piece 42, which is crimped behind the ange 40 and which is provided with a threaded part 43 that closely engages the projecting portion of the piece 22. The upper end of the part 42 may then be flanged inwardly around and crimped as at 44 behind the iiange 4I for locking the two parts together. A cap 45 can be threaded 40"prising two sections, an inturned iiange on the the bottle and provides a casing in which the;

valve 53 is movable. It also provides a valve seat 54. The tortuous passageway for theliquid is obtained in this modification by a plurality of. interconnected members 55 and 56. rPhe member 55 is cup-shaped and has a closed 4bottom tofgether with arms 51 that are attached to the part 56; the part 56, in turn, has a skirt 58 which extends into the cup-shaped member 55'and:has arms59 which .are bent outwardly and downwardly-into slots 6U that are-formed at spaced intervals in the wall of the toppiece 52. The slots may be formed by bending portions of the wall of the port 52 inwardly, as is shown at 6I, in Figpll. This modified construction is lsimilar in operation to that heretofore described and may be desired by some manufacturers in preference to-the other.

An important advantage of the present invention is the fact that the stopper parts .may vbe madeof sheet metal,.and therefore, theentire h assembly may be economically manufactured. Furthermore, the interconnectedparts maybe firmly attachedto each other and to thebottle so as to prevent unauthorized removal thereof without breaking the glass.
