L. A. IHLEIN NONREFILLABLE BOTTLE Filed Sept. 26, 1935 2 Sheets-Sheefc 2 INVENTOR` l ATTORNEY Patented .Fume 16, 1936 UNITED vslaras PATENT orale-a 'zclaima construction and arrangement of a nonrellable bottle wherein when the nonrellable feature is locked it cannot be reopened without breaking the bottle.

With the above and other objects in viewas will hereinafter clearly appear, my invention oomprehends a novel nonrellable bottle.

It further comprehends a novel nonrellable bottle having avent passage and a movable closure and novel means' for positively closing the vent passage and at the sam'e time retaining the closure in its closed position.

Other novel features of construction and advantage wlll hereinafter more clearly appear in the detailed description and the appended claims.

For the purposeof illustrating the invention, I` have shown in the accompanying drawings typical embodiments of it, which in practice, will' give satisfactory and reliable results. It is, however to be understood that the variousinstrumentalities of which my invention consists can be variously arranged and organized, and my invention is not limited to the exact arrangement and organization of these instrumentalities as herein set forth.

Figure 20 is a view similar to Figure 19 but showing the parts in different relation from that seen in Figure 19.

Referring first to the embodiment seen in Figures 1 to 7, inclusive, 1 designates a bottle having any desired contour to receive the nonrellable mechanism. The body portion of the nonrefillable mechanism is in the form of a casting 3 closed at its top and bottom except for an inlet opening 4 in the bottom and a discharge opening 5 in the top. 'I'he casmeans4 employed for closure in more than any desired or conventional manner. By way of illustration, I have shown an outer sleeve 6 cemented or otherwise secured in the neck and an inner sleeve 1, the sleeves having interlocking membersformed by tapered projecting portions 8 on one member in correspondingly shaped recesses 9 on the other member.

The casing 3 may be cemented, soldered or inner sleeve 1.

The inlet 6 has its marginal wall upwardly deected to receive the lower end of a flexible tubular valve I0 cemented or otherwise secured there-4 to. This valve -I is preferably of rubber, has its discharge end flattened and has its inlet end adapted to receive a ball valve II to seal it. 'I'he ball valve I I is in a skeleton cage I2 carried by the Vbottom of the casing 3, and the ball cage is of less diameter intermediate its ends so that the ball valve will be normally retained in the lower portion of the cage, so that the liquid can pass freely to and through the valve II.

I3 is a vvent passage, open at its upper end, and

and provided with a neckv 2 i f ing 3 may be xed in the neck of the bottle in 20 having a ilexible tube I4 connected lwith its lower v end and passing through the cage above the ball valve. The closure I5 has limited relative movement with -the top of the'casing 3 due to the prongs I6' which extend beneath .the top. A sleeve I 'I is secured to the closure I5 to1 receive a cord I8 fastened at one end to the closure. This cord I8 passes through Vthe valve I0 and has its lower 4end xed to the ball valve II. y.

Any desired 4bailling'arrangement may be used to prevent insertion of a wire or other tool to unseat the ball valve when the latter is seated in the`valve I0. A lower baille I9 has a general 56 conical contour with side discharge openings 20 and members 2 i. 22 is an intermediate baille 'with side discharge openings 23. 24 is an upper annular baie with'a central discharge o ning 25.

In the operation of this embodiment f my invention, when the parts are in the position seen in Figures 1 and 7, the liquid will pour from the bottle when the latter is inverted as seen in Figure'?. v

'I'he vent passage i3 at its upper end is provided with a check valve 26 of any conventional construction which is closed when the bottle is in upright position and which is open when the bottle is inverted for pouring.

When the bottle is empty, the operator turns the closure I5, thereby twisting the cord i8, and

raising the ball valve by the restricted intermediate portion which normally prevents the ball valve passing, outwardly.

The force of thejpull on the cord draws the bali valve by the restricted portion of the cage into thev valve Ii sealing its discharge opening as seen in Figure 3. At the same time it closes the exible tube le, thereby closing and sealing the vent passage and preventing the refilling of the bottle by suction and pressure. At the same time the closure i5 is drawn tightlyagainst the top of the casing 3.

As the ball valve ii cannot now be unseated due to its frictional grip on the `exible walls of the recess of the valve il, the bottle cannot be refilled unless the neck of the bottle is broken oi,4 thereby destroying the bottle for further use.

The conventional cap sleeve for sealing the closure i5 and the discharge opening 5 is employed when the bottle is shipped from the place where it has been filled, and removed when the bottle is to be used.

The embodiment seen in the other figures of the drawing is a preferred form as it is simpler and cheaper to manufacture.

Referring now to the embodiment seen in Figures 8 to 20 inclusive, I have shown in these iigures a preferred and simplified embodiment of my invention, wherein novel means are employed to positively seal the vent passage.

The casing 21 is similar to that in Figure 1, having a bottom with an inlet opening .28 and a j top with a discharge opening 29. The inlet opening leads to a tubular flexible valve 30, preferably of rubber. In order to :form a circuituous pas-- sage from the valve to the discharge opening 29, baies are employed. The lower conical baille 3l surrounds the valve and has its discharge opening directed laterally. The intermediate baffles 32 are in different planes forming a discharge opening 33, beneath the upper baille 34 which has openings 35 near its periphery. 1

An abutment 36 is spaced from the top face of the baille 34 which is fiat and has at its bottom an inclined face 31 which merges into a at bottom face 38. A vent pipe 39 extends from the upper baiile a desired distance below the casing and has at its upper end a check valve 40 similar to that shown in Figure 1. 4i is a closure for the discharge port 29 and has a raised rib 42 for grasping it. The closure 4l has L-shaped pins 43 which provide for relative movement between the closure and the top of the casing. The closure 4I has a right angle arm 44 depending from it and the free end forms a valve 45 having its top leading face tapered or inclined as at 49.

ures 8 to 20 inclusive is as follows. tie is inverted as in Figure 9 the liquid will cause the valve 30 to open and the valve of check valve .40 will drop downwardly opening thevent passage 39. The closure 4| will move downwardly and the liquid will pour freely from the bottle in the direction of the arrows seen in Figure 9.

When the bottle is empty and it is desired to seal it, the closure 4I is turned, the springs dii preventing any accidental rotation of the closure.`

As soon as the springs pass by the stationary stops 48 the closure can be given a one half turn. The springs 41 prevent the rearward rotation of the closure. The turning of the closure wedges the valve 45 beneath the abutment' 3G and closes the vent passage 39. At the same time, it draws' the closure 4I into rm engagement with the top of the casing to close the discharge port 29. As

When the botthe closure cannot now be turned in a rearward direction, there is no way of lling the bottle without breaking it.

In both forms of my invention as herein shown the vent is positively closed so that the bottle cannot be refined by a suction and pressure method.

The casing can be cemented to the bottle or to so a locking sleeve as in Figure 1.

Having thus described my invention, what I claim as new and desire to secure by Ttters Patent 1S:
