March 12, 1935. F. A. BUONO NONREFILLABLE BOTTLE Filed Dec. 11, 1955 INVENTOR {gal/7% .1 .fim/m [W ATTORNE i l f if d Patented Mar. 12, 1935 UNITED STATES:

JATENT orriee 2 Claims.

This invention relates to bottle closures and particularly toan improved closure of the nonreiillable type, the object being to provide an improved construction which is simple and yet efiective.

Another object-oi the pr'esent invention is to provide a closure which is strong and which readily functions to permit liquid to flowfrom a container but acts to prevent the entrance of a liquid.

An additional object is to provide in a closure of the non-refillable type, means which will automatically close by gravity, with one portion positioned interiorly of the other and substantially independent thereof so as to prevent any unauthorized adjustment at any time.

In the accompanying drawing-- Figure l is a longitudinal vertical sectional view through the container formed with a discharge neck and a closure structure embodying the present invention;

Figure 2 is a view similar to the upper part of Figure 1, but showing the parts in substantially inverted position whereby the liquid in the container will readily flow therefrom;

Figure 3 is a view similar to Figure l but showing a slightly modified construction;

Figure 4 is a view similar to Figure l but showing another form of the invention.

Figure 5 is a view similar to Figure 4 but showing a further modified form of the invention.

Referring to the drawing by numerals, 1 indicates a container of any desired kind. As shown in the accompanying drawing the container 1 is a glass bottle and is formed with a neck 2 of a desired size. The neck 2 is of the usual structure now in common use on the market and is adapted at the upper end to receive a stopper 8 in the usual manner.

This stopper 3 is desirable so that none of the liquid contents of the bottle can pass out when being shipped or handled. However", when the contents are to be used the stopper 3 is removed and, if desired, may be thrown away or reinserted after first use. The neck 2, in addition to being of the usual form exterior, is provided interiorly with a special division or partition 5-. The division or partition plate 4 is provided with an aperture 6 which is appreciably larger than the tubular member or shank 7 of the cap 8, which cap is much larger than the aperture 6 but smaller than the bore of the neck 2 whereby it loosely fits in this bore and rests tightly against the upper surface of the partition 4. The tubular member '7 acts as a guiding member for the cap 8, and also as a weight for holding the same normally in the position shown in- Figure 1. whereby the container 1 is maintained closed at that point. A plurality of springs 9 are carried by the lower end of the tubular member 7 and flare therefrom, the outer ends of these springs being adapted to strike the under surface of the division plate 4 when the bottle is inverted or substantially inverted as shown in Figure 2. Preferably the springs 9 are really resilient spurs extending from a central plate 10 and secured in any desired manner to the tubular member '1. It will be'understood that the tubular member (and the cap 8 may be made from metal, glass, porcelain or other material without departing from the spirit of the invention. The plate 19 is, however, preferably made from rust-proof steel orother desiraable material which will best serve the purpose.

The division member 5 does not extend straight across the interior of the neck 2 as is the case with the plate 7, but extends upwardly and forms a cam which merges into a tubularextension 11 preferably smaller in diameterthan-the aperture 6. This tubular extensionis provided with a beveled upper end forming a seat 12 against which the washer l3 presses wlienthe parts are in closed position. The washer 13 is arranged in a recess 14 in the cap 15, which cap is provided with inclined walls substantially parallel to the seat 12 but overlapping this seat for some appreciable distance, and then merging into a depending apron 16 whereby there is provided a spacebetween the apron l6 and the tubular extension 11. This provides a loose fit and one whereby the cap may be properly centered sothat the-washer 13 may fit properly against the seal 12. To assist in properly seating thevalve, to guide the same, and also to holdit always in position for proper actuation, there is provided a pin or rod 17 which is shown as being formed integrally with the cap 15, though it could be-inade separately and rigidly secured thereto. This pin or rod 17 is appreciably smaller than the bore of the tubular extension 11. It will thus beseen that the cap and all parts associated therewith are made of the proper size to loosely fit the tubular extension 11, except those parts which fit tigntly against the seat 12.

When the bottle or container 1 is in an upright position as shown in Figure 1, the cap 15 will be closed and also cap 8, thus preventing entrance of any liquid or other matter. However, when it is desired to remove any of the liquid from the container 1, the same is inverted or almost inverted as shown in Figure 2., whereupon the cap 8 will move down by gravity until the springs 9 stop such movement. This will leave a passageway around springs 9 and through aperture 6. The cap 15 will also fall down by gravity and by the force of the outpouring liquid, until it moves to the position shown in Figure 2 against the disc 10. It will remain centered as shown in Figure 2, or it may drop to one side, but the pin 17 cannot move away from the tubular extension 11. When the parts are in the position shown in Figure 2 liquid may freely fiow out of the container. If desired a small quantity may be discharged or the entire contents of the container. After a desired amount has been discharged it is only necessary to move the container to an upright position and the parts will again quickly assume the position shown in Figure 1. When in this position the two aligned openings are closed and substantially sealed, thus protecting the liquid in the container and preventing the entrance of any diluting liquid.

Figure 3 shows a slightly modified structure. In this form of the invention the same reference numerals will be used as in the preferred form, except that which refer to the modified parts. In this form there is provided an interior annular thickness 18 instead of a cone-shaped division plate such as member 5. This annular thickness or interior ring is provided with tapering'valve seat 19 adapted to receive a valve member 20 which is cone-shaped. This valve member is preferably covered with rubber or other material 21 which is slightly resilient whereby when. the cone is seated a tight connection is produced. Aside from these details the structure is identical with that shown in Figure 1 and functions in the same manner.

In Figure 4 a further form of the invention is presented, the structure being similar to that shown in Figure 1 except for the upper part. Instead of having a cap 8 there is provided a cap 8 having a tubular member '7' which is provided with a bore 22 extending entirely therethrough. This bore carries pistons 23 and 24 having piston rods 25 and 26. When the tubular member 7 is placed in position the piston rods are forced within the passageway 22 against the action of spring 27 and is held in this position by either the fingers or any other suitable instrument until the rods 25 and 26 have passed through the opening 6 which is larger in comparison than this opening 6. As soon as the piston rods are passed through this opening they are released and are immediately forced outwardly radially by the spring 27 until they slightly contact with or almost contact with the interior walls of the neck 2. Little or no friction is provided between the piston rods 25 and 26 and therneck 2. This is necessary in order to permit the cap 8' to readily move back and forth. However, these rods prevent the cap from being removed. Aside from these structures the device is identical with that shown in Figure 1 and the same reference numerals will be used except in the modified parts.

In Figure 5 a further modified form of the invention is disclosed wherein the head or cap 8" rests on the washer 28 so as to provide a tight fit when the device is closed. The tubular porindicated by the dotted lines. The piece 32 is provided with a single pin 33 extending therethrough,

though if desired this pin could be made integral with the piece 32.50 asto present integral trunnions extending therefrom. This vpin is fitted into a slot 34, it being understood that there will be two slots 34, because the structure shown in Figure 5 is in section. A spring 35 is wound around the pin 33 and has one end restingat 37, against the bar 32. This gives the bar a continuous tendency to press against the shoulder 38 at the end of slot 31. The parts are normally in position as shown in position, andthen the bar, tubular member 29 and associated parts are inserted through the open-. ing 6. As soon as the bar 32 passes through the opening, it will immediately and quickly move to the position shown in Figure 5. When in this Figure 5 when the device is r in operative position. Before the stopper has been inserted the bar :32 is turned to the dottedposition the stopper cannot be removed. Alongwith this stopper, a cap similar to cap15, shown in Figure 1, is used as an inner stopper, the same as is true of the structure shownin Figure 4..
