NON-REFILLABLE 'no'rTLE.

T 0 all whom it may concern:

Be it known that 1, JOHN J. ROBINSON,

a citizen of the United States, residing in the city of New York, borough and county of Bronx, in the State of New York, have invented a certain new and useful I1nprovement-in Non-Refillable Bottles, of which the following is a specification.

V The invention relates to that class of closures in which a spring actuated disk-valve is employed, and the object of the invention is to provide a simple and efficient device which may be economically manufactured and easily assembled, and w-hichwill permit the contained liquid to flow freely from the bottle, and effectually prevent refilling.

The invention consists in certain novel features and details of construction and arrangement by which the above objects are attained, to be hereinafter described and claimed.

The accompanying drawings form a part of this specification and show an approved ll respectively. Fig. 5 is a plan view of Fig. 6 is a corresponding the bafiie-disk. side elevation. Fig. 7 is a View of the under face of the same.

Similar letters of referenceindicate the same parts in all the figures. I

A is the upper portion of a bottle, constructed with a short neck A on which the closure is mounted and shaped to form a continuation thereof. prises two main portions one above the other; on the neck A is cemented the lower portion consisting of an annular shell B having a central opening I; surrounded by a lip B serving as a valve-seat for the diskvalve D, and having an annular channel exterior to the lip and below the latter. Above the shell B is the second portion or cap C having an annular skirt 0 the lower face of which is applied upon and cemented to the shell B.

The cap has a pouring orifice, 0 closed by a cork G, connected by a contracted passage 0 with a circular recess 0 in the lower face having an annular shoulder or offset C receiving the arms E projecting from the v and adjacent thereto.

The valveD' has ;a -stem D extending downwardly through .a guide or spider The closure comperiphery of a baffle-d-isk E of larger diameter than the passage partially closing the recess '0 and held central-1y thereof by its arms which are cemented to the shoulder, C Onthe lower face of the baffle-disk is a depending annular flange or"inv"erted cup E terminating above the valve-seat B Specification of'L'etteislPatent.

frame B in the opening I), and asimilar stem D extending upwardly and axially 1 of the cup. E is received in an axial hole in a boss E within the cup. A light delicate helical spring F encircles the portion D of the valve-stem and is partially inclosed in the cup E it abuts within the latter at its upper end, and at the lower end 'upon the upper face of the valve D, tending by itsslight expansive force to urge the valve to itsseat.

Whenithe corkGris removed and the bottle tilted the pressure of the valve D upon its seat, due to gravity, is lessened and the force of the liquid overcomes the resistance offered by the spring F, permitting the liquid to flow through the opening I) to the annular space 0* exterior to the cup E whence it passes through one or more of the passages 0 between the'arms E of the bafiie-disk E to the recess 0 and through the passage 0 to the pouring orifice c. The movement of the liquid past the valve causes the latter to apply upon the edge of the cup E as upon a valve-seat, and thus form a closed spring-chamber in. which the spring is inclosed and contact of the liquid 'with the spring is prevented. To facilitate such sealing of the spring-chamber or cup, the valve D is provided on its upper face with an annular groove (Z matching the skirt or lip of the cup; and within the groove is an annular ridge D forming a circular cavity of the same, or slightly smaller, diameter than the spring F and serving to engage the lower endof the latter. In attempting to refill the bottle the inflow of liquid, aided by the spring F forces the valve to its seat and closes the opening 6 as will be understood, and the arrangement of the passages 0 with the baflledisk E, relatively tothe pouring orifice 0- and valve D, prevents tampering with the latter by the introduction of wires or other instruments through the pouring orifice. The annular channel 72 serves as a receptacle for the small quantity of liquid which flows back through the pouring passages when the bottle is restored to its upright positioinand holds such liquid out of contact with the spring.

The parts B and C may be slightly conical or tapered externally, as shown, to simulate the usual form of bottle neck, and are joined to each other and to the neck A of the bottle by a suitable cement, and these portions are preferably inclosed in a slightly tapered-sleeve H of thin metal or heavy foil matching to and cemented thereon for purposes of reinforcement and ornamentation.

Importance is attached to the inverted cup E and its coaction with the valve D in forming a closed chamber for the spring F during the pouring operation and thus avoiding contact of the liquid with such spring.

The shell B, cap C and valve D are preferably of porcelain or'analogous material, and the spring F is of metal preferably non-corrosive in respect to the liquid contained in the bottle.

I claim The improved nonrefillable bottle herein described, comprising a shell having an with a contractedpassage and an annular l recess forming an annular shoulder, a battle disk having armsv engaging said shoulder,

said bafile disk having a depending inverted cup terminating above said valve seat, a

valve movable between the valve seat and the lower end of said cup and having upwardly and downwardly extended guiding stems, a guide within said shell for the lower stem and a guide within said cup for the upper stem, and a spring interposed betweenthe cup and valve, said valve being adapted to be seated against said seat when in one position and to seat against the adjacent end of the cup when the resistance of the spring-is overcome by the force of the liquid when the bottle is tilted.

In testimony that I claim the invention above set forth I affix my signature, in presence of two witnesses.

JOHN J. ROBINSON.
