SIDNEY W. PHELPS, OF SOUTHBBIDGE, MASSACHUSETTS.

' NON-REFILLABLE BOTTLE.

To all whom it may concern:

Be it known that I, SIDNEY W. PHELPS, a citizen of the United States, residing at Southbridge, in the county of lVorcester and State of Massachusetts, have invented a new and useful Non-Refillable Bottle, of which the following is a specification.

This invention relates to a non-refillable bottle.

The principal objects thereof are to provide a simple and effective construction whereby the bottle can be prevented absolutely from being refilled; and to provide a permanent seal for the bottom of the bottle adapted to be sealed after the bottle is once filled through the bottom.

Several bottles have been devised in which a valve in the neck is controlled by a weight hanging down into the bottle. So far as I am aware. however, these depend entirely upon the efiiciency of the mere weight of the counterweight below.

One of the important objects of this .invention is to provide means whereby the weight in itself will be able to exert a W8C ging action on the adjacent portions of the bottle so as to hold the valve firmly on its seat whenever the bottle is in inclined position.

Further objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawings, in which Figure 1 is an elevation of a bottle partly in section showing one form of the invention applied thereto; Fig. 2 is a sectional view showing the upper part of the bottle only and illustrating the parts when in inclined position; and Fig. 3 is a similar view showing the parts of the bottle in inverted posit-ion.

The bottle 10 is shown as provided with a neck having at some convenient point, preferably near the bottom thereof, a circular inwardly extending flange 12. This flange is provided with a central passage 13 therethrough, and on the top of the flange is a valve seat 14 which is shown as of hemispherical form. The lower side of the passage is provided with a surface 15 which gradually slants oil into the inner surface of the bottle. Above the valve seat 14 is an integral. inwardly extending ring or projection 16 having grooves 17 on its underside. Below this ring is a hemispherical valve 20 adapted to fit the valve seat 14.

Specification of Letters Patent.

Application filed October 23, 1909.

Patented Feb. 21, 1911.

Serial No. 524,163.

This valve is provided with a central, integral stem 21 which extends through the passage 13 and has rigidly mounted upon it below a counterweight 22. This weight is shown as of spherical form, and has passages or grooves 23 on its upper surface.

The operation of the device is as follows :-Vl1en the bottle is in upright position as shown in Fig. 1, the valve 20 is held on its seat by the combined weight of the valve and the counterweight 22, so that no liquid can be introduced without raising the valve. Then the bottle is inclined as shown in Fig. 2 the weight 22 moves down along the surface 15 and on account of the wedgeshaped cross section of the flange 12 and the gradual sloping shape of the surface 15 the valve 20 will be held to its seat as indicated in Fig. 2. not only by the weight of the counterweight 22 but also by the wedging action thus secured. It will be seen that the counterweight and valve are wedged on the opposite sides of the flange 12 so that in order to remove the valve from its seat it will be necessary to turn it so as to get'the weight 22 out of contact with the surface 15. This obviously is much more diflicult than merely to draw the valve forward in the neck as would be the case with those constructions in which the weight alone is depended upon to hold the valve on its seat in all positions of the bottle. It will be understood of course that on account of the shape of the valve and its seat a complete closure of the passage for the liquid will be obtained in all angular positions of the I valve. It will also be understood that although both the valve and its seat are shown as constituting complete hemispheres, most of the objects of this invention can be secured if either one of them is of this form, the other being of annular form, but its surface constituting a part of a sphere of equal diameter to that of the other part. In order to remove the contents from the bottle it must be completely inverted in which case the weight 22 rests on the surface 15 and covers the passage 13. The slots or passages 23 are provided for the purpose of permitting the liquidto pass out at this time. At the same time it will be understood that the top of the valve 20 will be close to the ring 16 so that the desirability of the passages 17 will be seen. It willbe understood of course that any of the ordinary well-known means may be employed in the neck in addition to the ring 16 for the purpose of preventing tampering with the valve if that should be thought necessary or desirable.

As a bottle constructed in this way must be complete in all its parts when it leaves the factory means outside the neck must be provided through which it- :an be tilled. For this purpose the bottom 30 is shown as of the reentrant style having a cylindrical projection 31 at the center thereof through which is a passage 32 comn'uinicating with the interior. 'l lnrough this passage the bottle is tilled preferably while in inclined position, so that the valve 20 shall be on its seat. litter the bottle is filled a cap 33 is placed over the projection 31. The edge 34 ot the cap extends inside a circular tiange 3.5 which projects in 'ardly and downwardly from the bottom (it the bottle. lie- .lore the cap is placed in position. the space between the flange an and the projection 31 is tilled with a glass ,'ement in a plastic form. Then the cap is placed in position and forced to its seat and the cement al lowed to harden. This permanently seals the bottle at the bottom. The cap preterably is provided with a groove 36 for admitting the cement, and forming a lock. it being observed that the lock on the outside is formed by the reentrant angle 37 at the bottom of the flange Preferably screwthreads 38 are employed between the projection and the cap for turther assisting in holding it while the same is hardening.

While I have illustrated and described a n'eferred embodiment of the invention, 1 am aware that many modifications can be made therein by any person skilled in the art without departing from the scope of the invention as expressed in the claims. ThOl'QlfOl'O I do not wish to be limited to all the details oi construction shown and described, but

What I do claim isz- 1. As an article of nianutactmre. a non refillable bottle having a neck provided with an opening theretlurmigh and at the. bottom thereol? an inwardly extending flange provided with an opening therethrough at the center. the top of said flange having a hemispherical valve-s all, and the bottom of said flange having a surface gradually sloping downwardly toward the sides ot' the bottle, a valve in the neck of the bottle above said flange of spherical shape on the bottom adapted to tit said valve seat in all positions thereof and provided with a central radia short stem projecting downwardly through said opening a weight heavier than said valve rigidly mounted on said sten'i below said flange and of such shape as to engage said sloping surface on the underside of the tlange when the bottle is tilted so as to cause the valve and weigl'it to be wedged on opposite sides of the flange, whereby the valve will be held lirmly against its seat whenever the bottle is tilted the said weight and valve being supported by the flange when the bottle is in inverted position, said weight having means whereby liquid can 'llow into the neck ot the bottle when it is inverted, and in ains in the neck for preventing the insertion of an instrument to hold up the valve.

As an article of manuizu'ture a non-refillable bottle having a body and a neck and provided at a point between the body and neck with an inwardly extending integral flange having a central opening. the

top of said .tlange having a hemispheritail valve-seat. and the bottom having a curved surface gradually sloping downwardly toward the sides ot' the body. the neck being provided with an integral inwardly-exteuding ring above said valve-seat having grooves tor the lower side tlnfircol a valve lilting said hemisphe-rical valve seat and having a short stem titted, through said opening and provided on the bottom thereoi with a counter weight l lavier than said valve in position to engage the curved surtace on the bottom of said liange when the bottle is inclined or inverted said weight having means whereby liquid can tlow into the neck oi: the bottle when it inverted, and means in the neck for preventiing the insertion of an instrument to hold up the valve.

As an article of manufacture. a bottle having an open neck provided at the bottom thereof with a flange extending inwardly and having a central passage therethrough the upper surface ot' said :tlange being provided with a valve. seat. and the lower surface thereof sloping gradually dowmvard toward the sides of the bottle. a valve adapted to tit on said seat in various angular positions and havinga stem extending through the passage, and a spherical weight mounted rigidly on said stem at a point immediately below the valve and adapted to engage said lower surface to hold said valve firmly on its seat when the bottle is tilted and ot sullicient size to fill said passage when the bottle. is inverted, said weight having passages along its upper surface adapted topermit the flow of liquid when the bottle is inverted said neck having means above said alve tor preventing the insertion of an instrument to hold up the valve In testimony whereof I have hereunto set", my hand, in the presence 0t two subscribing witnesses.
