Definitions

• Our invention relates to improvements in blottles and particularly to the necks of bott es.
• the object of our invention is to produce a bottle neck with a valve therein, the neck and valve being arranged in such a manner that liquid may be poured' freelyl from the bottle, but also in such manner that no liquid can be forced into the bottle; in this Way the fraudulent refilling of labeled bottles is prevented.
• our invention consists of a bottle neck, the construction of which will be hereinafter described and claimed.
• Figure 1 is a longitudinal section,-on the line 1-1 of Fig. 2, of the bottle neck embodying our invention.
• Fig. 2 is a sectional plan' on the line 2-2 of Fig. 1 and
• Fig. 3 is a broken perspective view of the bottle neck with parts in section.
• the bottle neck 10 may be of any usual exterior shape, and may beformed on any kind of bottle body.
• the neck has inserted in it a shell or bushing 11, which preferably abuts at its inner2end with a shoulder l0 in thev neck, and the shell is left open in the middle to form a valve chamber 12 and has, at its lower end, a collar 13 in which is a bushing 14, this being placed centrallyandforming a bore through which the liquid may be poured. If desired the bushing and collar may be made in a single piece.
• the bushing 14 is inserted in it a shell or bushing 11, which preferably abuts at its inner2end with a shoulder l0 in thev neck, and the shell is left open in the middle to form a valve chamber 12 and has, at its lower end, a collar 13 in which is a bushing 14, this being placed centrallyandforming a bore through which the liquid may be poured. If desired the bushing and collar may be made in a single piece.
• the bushing 14
• valve swings outward before the outflow ing liquid, Ypermitting the liquid to pass, but if the bottle is empty, or substantially so, the valve will close, even though the bottle be held with its neck lower than its body.
• the valve 15 has projecting from its free edge a guide'inger or stem 20, which swings in the slotted curved guide 21 projecting upward from one edge of the washer 17. It will be understood, however, thatV the guide and the clip 16 may be formed integral with the collar 13, if desired.
• the upper end of the shell 11 is closed by a plug 22, which is provided with a central bore 23 through which the liquid may be y 24 may be inserted to close the bottle.
• plug 22 has a reduced lower end 25 in which.
• valve attachment is inserted after the bottle is filled, and is placed in position so that it cannotbe removed without breaking the bottle.
• a collar inthe neck having a raised valve seat on its outerside, a flat spring-pressed valve held against the seat, a guide for the valve, and a plug held in the outer end ofthe having a spring connection with the clip and a guide stem to run in the curved guide, and 15 a plug in the outer end of the shell, the plug having at its outer end a stopper bore, its inner end reduced and side ports entering 'olie reduced end and connecting with the bore, substantially as described.
