JOHN KEER, OF TORONTO, ONTARIO, CANADA.

NON-REFILLABLE BOTTLE.

Application filed October 12, 1917.

To all whom t may concern.'

Be it known that I, JOHN Kenn, a subject of the King of England, residing at 'loronto7 Province of Ontario, and Dominion of Canada, have invented new and useful Improvements in Non-Reiillable Bottles, of which the following is a speciiication.

The invention relates to improvements in non-relillable bottles as described in the present specification and shown in the accompanying drawings that form part of the saine.

The invention consists essentially ofthe novel construction of the neck of the bottle whereby a ball valve is movably secured therein adjacent to the lower end and whereby a plurality of overlapping baille walls projecting inwardly from opposite sides of the wall of the neck form a protection for said valve from above.

The objects of the invention are to provide a non-reliliable bottle from which the contents can be poured quite freely but into which it will be impossible to force any liquid thus preventing the refilling of bottles from which the original contents have been withdrawn, and generally to produce a non-reiillable bottle which will be inex pensive to manufacture and secure.

1n the drawings Figure 1 is a vertical sectional view through the neck of the bottle.

F ig. 2 is a vertical sectional view through the neck of the bottle taken on the line A-A of Fig. 1.

Fig. 3 is a cross sectional view on the line B-B of Fig. 1.

Fig. fl is a cross sectional view on the line C-C of Fig. 1.

Like numerals of reference indicate corresponding parts in each ligure.

Referring to the drawings, 1 is the upper portion of the body of a bottle converging to the narrow central opening 2 and having the neck 3 extending upwardly therefrom in an elongated outward flare and merging into an intermediate globe portion Ll terminating in the cylindrical upper end 5, said neck adjacent to its lower end having the slightly curved portion 6 forming a seat for the ball valve 7 8 and 9 are baille walls extending inwardly from opposite sides of the globe portion f1, said baille walls being arranged one above the other and extending ahnost entirely across the opening through the neck of the bottle and overlapping each other.

Specification of Letters Patent.'

Patented June 3, 1919?.

Serial No. 196,286.

10 and 11 are bosses projecting inwardly from opposite sides of the neck S a short distance below the globe portion el and forining a stop for the ball valve 7 when the bottle is inverted.

12 is an annular ring around the neck 3 above the globe portion i to which may be secured any suitable seal.

13 is a tine wire secured to the ball valve 7 and extending upwardly through the neck 3 to facilitate the raising of said valve from its seat prior to pouring the original contents into the bottle, said wire being suiliciently fine adjacent to its eiigagement with the valve 7 to be easily broken after the bottle is filled.

It will be seen that the bottle can be easily filled so long as the wire 13 is secured to the valve 7 and said valve can be held midway between the bosses 10 and 11 and the valve seat 6 but as soon as the wire is broken the valve drops into its seat and chokes the entrance to the bottle. Owing to the overlapping arrangement of the baille walls it will be impossible to gain access to the valve 7 to hold it from its seat while the bottle is in its upright position and of course when the bottle is inverted it will be impossible to force any liquid thereinto past the said walls but if by any chance any liquid should pass said walls it will strike the valve and force it to its seat again and close the entrance to the bottle.

B y simply tipping the bottle suiliciently to allow the liquid to flow through the opening 2 the said liquid will pour freely from the bottle.

lt will be observed that the baille wall 8 curves slightly toward the open mouth of the neck while the bailie wall 9 is so positioned below the former wall that the facing surfaces of the two are substantially parallel throughout their length. Since the baihe wall S is inclined slightly upward, the path of flow of a liquid leaving the bottle is thus always from a higher to a ,lower point. This arrangement provides for emptying the bottle of all its contents and avoids danger of trapping any of the contents behind the baille walls.

Again, the neck is enlarged in the vicinity of the baiile walls and the free ends of these walls terminate in this enlargement beyond iniaginary lines drooped from the inside walls of the cylindrical. upper end 5 directly above these free ends. Thus, an instrument lll) to be inserted around the free end of the baiiie wall 8 must be inclined away from the side wall of the upper portion 5 standing' directly above this free end of the bailie plate. Therefore, such an instrument or wire would be inclined at an angle such as would make it impossible to direct the end of the wire around in the space between the two baffle walls.

What I claim is:

In a non-rellable bottle, a neck having a cylindrical upper end open at the top, this cylindrical end merging into an intermediate globular portion, the neck thereafter tapering in shape and terminating in a restricted portion forming a ball valve seat, said globular portion having opposed overlapping baiile walls the free ends of which terminate beyond imaginary lines dropped from those inside walls of the cylindrical portion directly above the said free ends, the upper baille wall inclining slightly upward and being uniformly spaced throughout its length from the lower battle wall, whereby a liquid in passing through the neck moves always from a higher to a lower level to prevent trapping of the liquid behind the bafe walls, the cylindrical end being unobstructed between said imaginary lines above said baiile walls, the tapering portion of the neck having diametrically opposed inwardly projecting tongues, and a ball valve engageable upon the said ball valve seat to close communication between the bottle and the neck, the said valve being also engagei able upon the tongues when the bottle is in inverted position at which time a liquid may pass freely around the ball in flowing through the neck,

Signed at Toronto, Ont., this ninth day of 40 October, 1917. Y

JOHN KEER.
