2 Claims.

The present invention relates to new and useful improvements in bottles in general and has for its primary object to provide, in a manner as hereinafter set forth, .a bottle which may be readily emptied but which, after being emptied, can- Anotherimportant object of the invention is to provide a non-refilling closure for bottles of the type including a reciprocating check valve, together with novel means forpreventing tampering with said valve, as by the insertion of an instrument. e I

Other objects of the invention are to provide a bottle of the aforementioned character which will be comparatively simple in construction, strong, durable, highly efiicient and reliable in use and which may be manufactured at low cost; g All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawing wherein like characters of reference designate corresponding parts throughout the several views, and wherein:

Fig; 1 is a view in vertical section through the neck portion of a non-refillable bottle constructed in accordance with the present invention.

Fig. 2 is a view in top plan thereof. Fig. 3 is a view in horizontal section, taken substantially on the line 3 -3 of Fig. 1. V

Fig. 4 is a vertical sectional view through the stopper, taken substantially on the line 4-4 of Fig. 1. Referring now to the drawing in detail, .it will be seen that the embodiment of the inventionwhich has been illustrated, comprises a stopper 5 which is mounted in the neck 6 of a bottle below the upper end of said neck, as seen in Fig. I of the drawing. The neck 6 and thestopper 5 have formed therein opposed grooves 1 and 8, respectively, for the reception of a split, resilient ring '9 which constitutes means for securing said stopper 5 inthe neck. In assembling, the ring Sis placed' in the groove 8 and contracted for insertion in the bottle neck, said ring snapping into the groove I when the stopper reaches this'lpoint. Formed in the lower portion of the neck 6 is a flange I0 which provides a port I l and a valve seat 12.

Depending from the stopper 5 is a stem 13 having spaced flanges l4 and ISthereoriproviding annular channels I6; Extendinginto thestopper' 5 from the top thereof is a socket I 1 which communicateswith-the upper channel [6 through downwardly diverging ports I8. The flanges l4 and I5, have formed therein spaced peripheral fluidpassages I9, thepassages I! in the flange 14 being out of align'mentwith the ports l8 and the passages in the lower flange I5 for preventing the insertion of an instrument should it be: attempted to tamper with the valve to be presently 'de-; 'scribed. The stem I 3is provided with a reducedlower end portion 20 which extends into the port ll r and terminates in a head 2 l,.said reduced portion 20 providing a shoulder 22. Slidably and rotatably mounted onv the reduced portion or shank. 20 is a valve 23 of suitable material which is en-' gageable on the seatl2 for closing the should it be attempted to refill .thebottle. V It is' believed thatrthe operation ofthe invenis being emptied, the liquid therein flows through the port I through vthe'passages I9 and thechannels [6, through the ports! and then through the socket or pocket I! of the stopper 5. The,

valve 23 is readily disengaged from itsseat l2 to permit the discharge of the liquid in, this manner, However, should it be attempted to refill the -bottle, the'inflowing' fluid seats the valve 23for closing the port ll. Further; when'the bottle.

is in an upright or a substantially upright'position, the valve 23 engages by gravity on the seat I2. The shoulder 22limits movement ofthe valve 23 toward open position." Ashereinbefore stated, by reason of the fact that the passages IS in the flange 14 are out of alignment with the ports l8 and the passages in the lower flange lithe insertion of an instrument for the purpose of tampering with the valve 23 will ,bepreventedL I The top of the head-2| is flush with the seat l2 andthe valve 23; also seats on said head'2l in a manner to prevent leakage between said valve and-the stem 20. The'valve 23 is of buoyant material, preferably cork, and said valve possesses sufficient resiliency-orv elasticity to permitthe, same to be passed over the head 2]., As illustrated to advantage-in Figures! ofth'e drawing, the retaining ring 9 is of polygonal cross section to conform to the grooves l and} and prevent longitudinal movement of the stopper 5 the bottle neck; When expanded, the resilient ring 9 seats inthe groove 1 but isalso partiallyengaged in the groove 8. 7

with the present invention will be readily under- "construction and in the combination and arrange- It is believed that the many advantages of a non-refillable bottle, constructed injaccordance stood, and although a preferred embodiment of f 3 the invention is as illustrated and described, it is to beundersto'od thatchanges in thedetails of tion will be readily apparent, When the bottle l ment of parts may be resorted to which will fall within the scope of the invention as claimed."

What is claimed is: g p l 1. A non-refillable bottle comprising a neck, a valve seat in said neck, a stopper mounted in the neck having fluid passages therein, a stem depending from said stopper, a head on the lower end of said stem' flush with the valve seat, and a valve slidable on the stem and engageable with the seat for preventing the flow of fluid into the bottle, said valve further being engageable with the head for preventing leakage between the stem and the valve.

2. A non-refillable bottle comprising a neck, a valve seat in said neck, a stopper'mounted in the neck, a stem depending from said stopper, spaced flanges on said stem having staggered fluid passages therein and defining annular channels, the

stopper having a chamber extending downwward- 1y thereinto and further having downwardly d1- verging parts establishing communication between said chamber and the uppermost channel, the stem including a reduced lower end portion providing a shoulder, 'a head on the lower end of said reduced portion flush with the seat, and a valve slidable on said reduced portion between the shoulder and the head and engageable with and the reduced portion of the stem.
