NON-REFILLABLE BOTTLE.

Specification of Letters Patent.

Patented Jan. 29, 1918.

Application led December 26`I 1913. Serial No. 808,846.

To all whom it may concern.'

Be it known that I, LOUIS LANDOLFI, a subject of the King of Italy, and residing in borough of Manhattan, city, county, and State ot New York, have invented certain new and useful Improvements in Non- Refillable Bottles, of which the following 1s a specilication.

This invention relates to non-reillable bottles, and aims to provide certain improvements therein.

The object or' the invention is to provide a bottle which cannot be refilled either inverted or on its side, or by means of suction or pressure, or a combination of these.

In carrying out the invention I provide a bottle having a diaphragm or plug provided with opposing valve seats, which coact with two valves which are mounted upon a common shank extending through the plug or diaphragm. These valves are normally loaded by a. light spring which tends to preserve the uppermost valve in its closed position.

y Preferably the lowermost valve is provided with a plate which is designed to be moved by the outgoing liquid, thus unseating the top valve. This plate is of particular advantage in connection with what are known as shaker bottles designed to receive a great variety of liquids, and to be capable of delivering drops or small portions of liquid when the bottle is Shaken.

Referring to the drawings illustrating the present invention, let A indicate the bottle, having a cap 'B which in the presentinstance includes the various parts of the mechanism provided by the invention. Obviously these parts can be depressed within the neck ot the bottle if desired. The cap B is provided with a plug or diaphragm C which in the present instance is shown as screw-threaded into the cap. The plug C is formed with a central bore D which extends centrally through it and terminates at its upper end in a valve seat E. At its lower end the plug is provided with a valveI seat F.

Extending through the bore D is a stem G which carries at its upper end a valve II and at its lower end a similar valve I. The valves II and I are shown as spherical valves and when these are used the seats E and l are correspondingly shaped.

At the bottom ot the valve I is arranged a light weight plate .I which may be made of aluminum which serves as a convenient bottles the impact of the liquid against the plate J forces the valve from its seat, thuspermitting a slight amount of liquid to pass through the bore D. If desired the spring K may be so proportioned as to yield sulficiently to permit the valve I to reach its seat during the operation'ot shaking, thus closing the outlet until the bottle is again shook.

Preferably the plug C is formed with a nozzle M which is closed at its outer endby a cap N and provided with lateral apertures O, the purpose of this being to prevent insertion of an instrument through the nozzle P of the cap B to dislodge the valve.V

In operat-ion the liquid within the bottle is easily discharged while at the same time it is impossible to reiill the bottle. If the bottle upright the valve I-I prevents the ingress of liquid supplied through the nozzle P. The same is true when the bottle is inverted or on its side. If suction is applied to the bottle, the tension of the light spring K Vis overcome and the valve I seats, thus preventing the ingress of liquid. In the con- .struction shown wherein a plug having two oppositely arranged valve seats is employed together with two valves having a connecting shank, the upper valve is directly in line with the flow of liquid in case'of an attempt to till under pressure, and the valve is hence sensitive and accurate in its movements. On the other hand, the inner valve is directly in line with the How of air if suction is applied and receives vthe full effect of the air current. Furthermore, the whole device is compact, and takes up little room in the neck of the bottle.

It is apparent that many changes can be made in detail without departing from the invention.

What I claim isz- Y l. A non-refillable bottle having a diaphragm provided with valve seatspn its opposite sides, an outwardly opening valve contacting with the outer seat and an inwardly opening valve contacting with the IVhen the bottle contains liquid,v

inner vseat7 said Valves being connected to 1no'.'e together, a ,spring normally tending to hohl the outer valve on its Seat, and a plate connected with the lower valve' and arranged below the diaphragm, and exposed io the impact or the liquid.

2. A shaker bottle having a diaphragm provided with a valve seat on its outer side, a valve opening` outwardly from said seat, a member extending through said seat to the inner side of said diaphragm, a plate iixed to said member and adapted to be moved by the impact of the liquid, a Spring adapted to normally eloSe said valve, a second' valve Seat on the under side of said daphragm and a second valve opening` inwardly and connected to said member.

In Witness whereof, I have hereunto Signed my name in the presence of two subscribing Witnesses.
