I v Inventor Attorney Patented Jan. 5, 1943 UNITED STATES PATENT 2,307,325 NONBEFILLABLE BOTTLE Oliver H. Lee, Port Clinton, Pa. Application April 19, 1941, Serial No. 389,446

1 Claim.

This invention relates to a non-refillable bottle, the general object of the invention being to provide simple means whereby the non-refillable means can be placed in the neck of the bottle below the mouth thereof so that a cork or other sealing medium can be used, the invention permitting liquid to be poured from the bottle but preventing liquid being poured in the bottle and such means also preventing the device being rendered inoperative through means of a wire or the like.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts to be hereinafter fully described, illustrated in the accompanying drawing and specifically pointed out in the appended claim.

In describing the invention in detail, reference will be had to the accompanying drawing wherein like characters denote like or corresponding parts throughout theseveral views, and in which:

Figure 1 is a vertical sectional view through the neck of a bottle provided with the invention.

Figure 2 is a top plan view of Figure 1, and

Figure 3 is an exploded view of the various parts of the non-refillable means.

Referring to the drawing, the letter A indicates the neck of a bottle and in carrying out the invention a groove I is formed in the neck an appreciable distance from the top thereof so that a cork or other sealing means can be used for closing the mouth of the bottle. An annular bead 2 is also formed in the neck below the groove. A cylinder 3 having a reduced cylindrical end 4 is placed in the bottle and a ring-shaped seal 5 of rubber, cork or the like is placed over the part 4 and fits snugly the internal wall of the bottle neck below the groove with the end of the part 4 and part 5 resting against the bead. The upper end of the part 3 is formed with notches 6. The upper end of the part 4 where it joins the bottom of the part 3 is formed with an upstanding bead 'l which forms a seat for a valve disk 8 which is located in the par-t 3. A shell 9 has its top closed and its bottom open and the sides of the shell are formed with the" tongues it which are provided by making substantially inverted U-shaped cuts in certain parts of the device and these tongues are bent outwardly, as the parts are pressed in place, as shown in Figure 1, so that these tongues will have their upper ends engaging the top wall of the groove i so that the parts are locked in the mouth of the bottle. Vertical grooves or recesses H are formed in the sides of the shell between the parts having the tongues formed thereon and each part II will space portions of the shell from the internal walls of the bottle neck but they will not expose the parts having the tongues Ill therein so that these tongues cannot be reached by a wire or the like in an attempt to remove the device from the bottle neck. A slight depression i2 is formed in the central part of the top of the shell to form a seat for the valve 8 when the bottle is inverted so as to prevent the valve from sticking or being held to the top of the shell so that the valve will dropback upon the bead i when the bottle is placed in upright position again.

From the foregoing it will be seen that after the parts are put in place as shown in Figure 1 they are firmly held in place and cannot be re moved and after the cork or sealing member has been removed and the bottle inverted liquid will flow therefrom past the valve 8 which is unseated, due to the partial inverting of the bottle and then this liquid will pass through the notches 6 into the shell 9 and then through the openings formed by the tongues H] into the groove l and then the liquid will pass through the recesses H into the bottle mouth and thus be poured from the bottle. As soon as the bottle is put in upright position again the valve 8 will drop upon its seat I and thus prevent any liquid from being poured into the bottle. If an attempt is made to have liquid enter the bottle by placing the same in a supply of liquid with the bottle inverted the pressure of the liquid will move the part 8 upon the seat l.

Thus it will be seen that I have provided a simple device for rendering a bottle non-refillable.

As will be seen the bottom of the groove slopes downwardly and inwardly and when the shell 9 is pressed into place the lower ends of the tongue carrying parts will be forced inwardly and downwardly by this angular lower part of the groove so that the tongues Ill will be automatically moved into the groove as shown in Figure 1. This device could be put in place with a bottle filling machine.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts provided that such changes fall within the scope of the appended claim.

Having described the invention, what is claimed as new is:

In a bottle having an neck, the groove having a annular groove in its downwardly and inwardly sloping bottom wall, a valve seat forming ing adapted to fit over the valve carrying pa: member of tubular construction looated in the and the ends of the tongue carrying parts bein neck and a valve for engaging the seat and movpressed downwardly and inwardly when the shel able oif the seat when the bottle is tilted into is pressed into place. by the angular bottom 0 pouring position, a shell having its bottom open 5 the groove, to move the tongues into the groov and the sides having grooves therein and tongue for locking the shell in place.

carrying parts between the grooves, said shell be- OLIVER. H. LEE.
