NON-REFILLABLE BOTTLE.

Specification of Letters Patent.

Patented July 14, 1908.

Application filed January 9, 1908. Serial No. 409,925.

T 0 all whom it may concern:

Be it known that I, VALENTINE SAND- BERG, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Non-Refillable Bottle, of which the following is a full, clear, and exact description.

This invention relates to that class of bottles in which certain obstructions are located in the neck to prevent the same from being refilled, but permitting the contents thereof flow of the liquid will not be impeded.

to freely flow out when the bottle is uncorked and inverted.

The invention has in view a bottle of this nature of comparatively simple construc tion, which may not be refilled by any of the methods ordinarily resorted to, such for example as by infiltration, suction, etc. To this end 1 preferably construct the neck of the bottle with a shoulder and an annular groove, the groove being located above the shoulder and connecting with passages arranged at substantially diametrical points and extending in the direction of the'mouth of the bottle. On the shoulder of the neck is seated a tubular body having a spring pressed valve, and provided thereabove with openings at the sides discharging through said groove and passages, the latter extending slightly above the body, whereby the The spring which forces the valve to its seat is of such stiffness as to readily open under the weight of a small quantity of liquid when the bottle is inverted, but will immediately close when the bottle is exhausted.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a central vertical section through the neck of a bottle embodying my invention; Fig. 2 is a like sectional view showing the flow of the liquid when the bot tle is inverted; Fig. 3 is a cross-section sub stantially on the line 3-3 of Fig. 1 and Fig. 4 is a perspective view of the tubular body which is located in the neck of the bottle.

The body of the bottle may be of any desired form of construction the neck, however, is expanded at its lower portion to provide a shoulder 5, an annular groove 6, ar-

ranged above the shoulder, and at diametrically opposite points in a longitudinal direction, as best shown in Fig. 3, to provide passages 7, connecting with the groove 6 and discharging a substantial distance thereabove.

Located in the neck of the bottle is a tubular body 8, which is made in two sections fitted together, with one or more tongues 9 formed on one section and projecting into the other, holding them against relative rotation. The upper section of the tubular body is closed at its upper end and provided with openings 10, for the discharge of such liquid as passes above the valve, and the lower sec tion is constructed with a valve seat 11, and has openings 12 arranged at opposite sides above said seat and communicating with the annular groove 6. The lower section of the tubular body is also provided with an external flange 14 which provides an abutment for a suitable cork or gasket 15, forming a liquid-tight connection with the lower portion of the tubular body and. the bottles neck. The valve seat in the tubular body, as best observed in Fig. 1, has an upwardlyprojecting annular lip 16, which closely fits within a hollow valve 17, when the latter is seated, the valve being normally forced to its seat by a spring 18, which is interposed therebetween and the top of the tubular body; the said spring being held against displacement by reducing the top of the valve sulficiently that the same may project therein. The diameter of the enlarged portion of the valve 17 is such that it neatly fits the bore of the tubular body, and in order that the liquid. may fiow past the same to the openings 10, the said bore is constructed with a number of longitudinal grooves 19. 18, which in practice is a hair spring, is of such stiffness as to hold the valve normally to its seat, but will admit of its opening under the weight of a small quantity of liquid in the bottle when the latter is inverted, and accordingly does not substantially impede the flow of the liquid but prevents the bottle being refilled by infiltration.

The tubular body when placed within the neck of the bottle has the top thereof arranged slightly below the top of the passages 7, and is secured within the neck in any suitable manner. I have shown for this purpose a split-ring 20 which is arranged in a circum- The spring ferential groove of the body and projects in a corresponding groove formed in the neck. The top of the tubular body is provided with a fiange 21, which neatly fits within the neck of the bottle and prevents the insertion of wires or other devices between them, and as the openings 12 are arranged at substantially right-angles to the passages 9, it will be impossible to reach the valve 17 by passing such a device down through the passages 7.

It is, however, not essential that the openings 12 be arranged at right-angles to the passages 7, it is only necessary that they be out of vertical alinement. The neck of the bot tle extends a suitable distance above the tubular body for the reception of a cork or other form of stopper.

While I have shown and described the preferred construction of my invention, I nevertheless regard the precise embodiment as not material, and consider that I am entitled to such changes as fall within the scope of the claims annexed.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1. The combination of a bottle having a neck provided with a circumferential groove, a tubular body located in the neck and having an opening communicating with the groove, said neck also having a connecting passage discharging above the body, and a valve in the body controlling the communication between the interior of thebottle and the opening in the side of the body.

2. The combination of a bottle having a shoulder in the neck thereof and a circumferential groove in said neck above the shoulder, a tubular body having a liquid-tight joint with said shoulder and provided with openings in the side thereof registering with said groove, said neck also having longitudinal passages connecting with said groove, out of alinement with said openings and discharging abovethe body, and a valve within the body for controlling the passage of the liquid from the bottle through said openings.

3. The combination of a bottle, a body located in the neck of the bottle having a liquid-tight joint therewith at its lower end and provided with an approximately central bore, said body being further provided with a discharge opening in the side connecting with the bore, the said neck having a discharge passage leading from the opening to a point above the tubular body, and a valve in the body controlling the communication between the interior of the bottle and the open- 1n 2 a. The combination of a bottle having a shoulder in the neck thereof, a body having a liquid-tight joint around said shoulder and provided with an approximately central bore, said body being further provided with a discharge opening in the side connecting with the bore, the neck of the bottle being exp anded to provide a' passage leading from the opening to a point above the body, and a valve for controlling the communication between the interior of the bottle and said opening.

5. The combination of a bottle, a tubular body located within and substantially fitting the neck of the bottle and having an opening in its side, the neck of the bottle being expanded to provide a passage leading from said opening above the body, a valve within the body controlling the communication between the interior of the bottle and the opening, and a spring arranged above said opening and interposed between the top of the body and the valve, normally forcing the valve to its seat.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

VALENTINE SANDBERG.
