(clizia-12p) Theinvefntion relates to non-reilllable bottles and more-particularly .toJa simply constructed tamper proof valve unit readilyyinserted and sealed within a conventional bottle neck. An object vof the invention is .to providea nonrellable bottle having a valver unit `therein of a character which is inexpensive to manufacture and may be Vvmanufactured, distributed or sold apart from thebottle and readily sealed therein.

Another object is to provide a `bottle with a gravity actuated valve unit embodying 4a minimum number of `movablepartscofrelated to prevent reillling.. of the bottle, .without materially restricting the rate ofrdischarge therefrom.y The foregoing and such other objects of the invention as may appear hereinafter as the de,-

scription proceeds will be more readily under` stood from a perusal of the following specification in which reference is had to the accompanying drawing, wherein:

Fig. 1 is a longitudinal sectional view, with parts in elevation, through a bottle neck having the improved valve unit therein.

Fig. 2 is a view similar to Fig. 1 showing the bottle substantially inverted, and the valve open.

Fig. 3 is a view similar to Fig. 2 showing the bottle fully inverted.

Fig. l is another sectional view similar to Fig. 2 showing the bottle tilted substantially beyond horizontal and the valve closed.

Fig. 5 is a horizontal sectional view taken on line 5-5 of Fig. 1.

Fig. 6 is a horizontal sectional view taken substantially on line 6 6 of Fig. 1.

I'he present invention is s own embodied in a self-contained unit readily inserted within the neck of a conventional type of bottle and embodying means to facilitate its being sealed-or otherwise securelyl attached thereto to prevent its unwarranted removal. The unit preferably consists of a substantially cylindrical shell II made of any suitable material, such as for example, glass or plastics, enlarged at its upper' end to provide an annular external shoulder I2 arranged to seat tightly against the top edge of the bottle neck I3. The upper and lower ends of the cylindrical shell integral end walls I4 and I5 respectively.

The wall I4 may have a suitable pouring spout I6 thereon suitably constructed to receive a cap I1 for normally closing the container. Although the cap II is shownin the form of a plug or cork, it is obvious that any suitable screw or flanged cap may be utilized upon providing the required threads or flange on/the spout I6. The lower preferably are closed by ,In this manner, the

wall I5 `is providedfwith an axial concave valvel "seatISon its inside surface milled on a radius equalto'the radius of aclosure or valve .body I9 which, as shown, preferably is in the form of a *sphericalv body. The closure vI9 be of i any 'suitable-material having'a non-porous surface;

consequently*itl'is very 'preferable that it be made of glass. For purposes to be made evident hereinafter, it is advisable to-keep the weight of theclosure I9 at a minimum hence, when glass is used the closure preferably is hollow as shown. f

A partition 2| is formed integral with the cylindrical shell II, preferablyparallel to and spaced but-a short distance from the wallfI4. 1 This' partition has a pluralityv of perforations' or otherfsuitable openings' `22 circumferentially spaced'about its outer margin-providingcomrnunicati'onA kpassageways 'between upper 'and lower chambers 23 and 24 respectively, provided thereby in the shell. A circular flange 25 extends downwardly from the bottom face of the partition 2l, said flange preferably being in axial alignment with the valve seat I8.

A weight 26, preferably made carried within the shell Il, above the closure I9 in the lower chamber. As best shown in Fig. 1, the weight 25, which also is spherical, may have a heavy core and is of such span the distance between the bottom edge of the flange 25 and the upper peripheral surface of the closure I9 when in the position illustrated.

closure I9 against the Valve seat I8 while the bottle is moved through the various angular positions a`s. sumed when being inverted to discharge its cons tents. The weight 26 will remain in 'a position shown in Figs. 1 and` 4 until such time as its center of gravity (broken line G) passes inwardly vbeyond the line of contact between said weight and the flange 25 whereupon said weight rolls into a recess 2'I defined by said flange. In this manner the distance between the circumferential surface of said weight andthe valve seat I8 is increased and the closure member I9 is free to fall away fromsaid seat thus permitting the contents of the lbottle to flow into the lower chamber 24 of the cylindrical shell, through the passageways 22 and out of the pouring spout I6. Displacement of the closure I9 is providing spaced guides 28. Whe'n the bottle is being returned to its upright position, the closure I9 is urged against the valve seat I8 as soon as the center of gravity ofthe weight 26 moves past the circular flange, consequently the bottle of glass,l also is? a diameterv as to is held tightly prevented by is sealed prior to its reaching a substantially two longitudinal halves subsequently joined;`

after placing the parts I9 and 26 therein.

The size of the weight 26 also is importar-it lief with respect to the inside diameter of .theshell l which necessarily determines the rest or closure position of said weight, and consequently Sits position with respect to the closure I9 and :Harige 25. It will be observed upon reference 4tolig. 4,

that: although the bottle is illustrated .ina posiftionttilted.- substantially below fthe horizcntalthe -valve is closed. Consequently, Aflu-idx cannotfiorcibly :be #admitted into :the bott-le while held -in substantially -lth'at :posit/ion. .'Also, due to l:the comparative -light weight of the-'closure izany attempt to evacuate the: partially inverted nbottle of` atmosphere `to 'effect azfiowof liquid ,.therein will be. defeated because'fsuch attemptedr evacuation will Acause `said closure to move tightly ragainstts Ivalve seat.

To 'prevent 4unwarranted moving-A of the parts when not' in use, fa sstem 129 is provided 'on 'the bottom face ofthe-cap Y'I'l to extend .through-a minute apertureiSl :in thepartitionJZl and-aen- -gage against the surface of the weight 26. :Ac- .cordngly, 'Whenfthecap -H ,is :in thelposition rshownin-Fig. 1, thet members le and 126 rcamiot become displaced or be rattled. The entire unit may be sealed in the bottle neck by providing a conventional internally anged metallic retaining ring 32 or by any other approved means. Upon destruction of the bottle when emptied, the valve unit may be readily removed after breaking .said ring.

Although an exemplary form of the invention has been illustrated and described in detail it is toebemnderstood that the --disclosure is not re- `:s'tr-ictive but thatthe invention islto embody such modifications as will appear within the spirit of fthe invention and the scope of the appended claim.
