Specification of Letters Patent.

Patented June 22, 1915.

Application filed August 15, 1914. Serial No. 856,937.

To all whom it may concern:

Be it known that I, OTTO SPAHR, a citizen of the United States, residing at. Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented a new and useful Improvement in Bottle-Closures, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which form a part of this specification.

The object of my invention is to provide a cap or closure for bottles and more especially for. application to bottles of milk after the same have been delivered by the dealer to the housekeeper.

More specifically, the object is to provide a closure which when not in use will seal the bottle but which will allow the milk to be readily poured from the bottle without removal of the closure.

Bottle caps of this kind are known in the art, but the same are open to Various objections, such as inadequate closure, difficulty of application and removal, imperfect provision for proper outlet of the milk in pouring, expense of manufacture, etc. In my invention these defects are overcome.

The invention will best be understood by reference to the accompanying drawings, in whioh- Figure 1 is a perspective'view showing the cap applied to a bottle held in position for pouring. Fig. 2 is a plan View of the cap with the gate turned in position to open the pouring orifice. Fig. 3 is a section on the line 3-3 of Fig. 2. Fig. 4 is a plan view of a modification with the gate in position to close the pouring orifice. Fig. 5 is a section on the line 5-5 of Fig. 4.

From a flat piece of metal, by cutting or bending, is formed a flat disk a provided at one side with the upwardly deflected pouring spout b and throughout the remainder of the edge of the disk with downwardly extending spring flanges 0. The flanges are adapted to engage the outside flange or rim at the upper end of the neck of the bottle. By making these flanges substantially contiguous one to another, I have found that when the cap is applied to the bottle 00, it will be held tightly thereon without the provision of washers between the disk and hottle and without the necessity of dishing in the central portion of the disk to provide a shoulder engagement of the cap with the inner edge of the top of the bottle neck.

he metal of the disk is also cut away on one side of its center and back of the spout b to provide an orifice d for the escape of the milk. The metal is also cut at the two opposite front corners of the orifice d to form forwardly extending notches e, e. The metal between the notches e and e is bent down to form a lip 7, which is shaped to fit the inside wall of the bottle neck immediately below the latters upper edge. This lip, which is preferably of less length than the width of the spout 1), assists in tightly holding the cap on the bottle, but it also performs the function of directing the flow of the milk toward the spout. The spout, whose width, measuring circumferentially, is preferably considerably greater than its length, measuring radially, is bent up at its opposite corners on lines extending obliquely toward the central front portion of the spout from points at the junction of its extreme ends with the disk a.

Applied to the top of the disk is a gate for closing the orifice d, this gate comprising preferably a half disk g, superposed upon and contacting with half of the disk a, and a flange it extending upward from the straight edge of the half disk at right angles thereto. The half disk, at the center of its straight edge, has a semi-circular extension y', and a rivet 2' extends through the center of this extension (which is in alinement with the straight edge of the disk) and through the disk, thereby affording means whereby the gate may be turned on the rivet as an axis either to close or open the orifice d. The flange it affords a convenient handhold for turning the gate.

lVith the construction above described, the cap or closure may be readily applied or removed, the closure is secure when the gate is moved into closing position, the use of a washer is unnecessary, and there is no danger of any of the milk that is poured from the interior of the bottle flowing upon the top of the disk either in the act of pouring or in the return of the bottle to a vertical position after pouring is completed. The shape of the spout and the provision of the lip beneath the spout insures that all the milk will be directed to the mouth of the spout in the pouring operation, and the construction permits the pouring orifice to be made of suflicient size to avoid the necessity of providing a special air inlet. It is obvi ous that the whole device may be readily cut and stamped from sheet metal and may therefore be cheaply manufactured.

The construction shown in Figs. 4 and 5 is the same as that hereinbefore described so far as concerns the body of the closure, but the gate is arranged to open and close automatically. In the disk a is formed a slot m which extends at right angles to that diameter of the disk which intersects the center line of the spout. A semicircular gate a is provided with an integral arm 0 extending from the center of the straight edge of the gate, said arm, just beyond its point of connection with the gate, being bent at an angle to the gate n. This arm may be bent upon itself to increase its Weight. This construction affords a hinged or pivoted connection between the gate and the disk, and the arm also acts as a counterweight to assist in swinging the gate open when the bottle is tilted into pouring position and in closing the gate when the bottle isreturned to a vertical position. This construction has the advantage over the one just described of affording an automatically operating gate, although the gate does not close with the same degree of tightness as the gate of the first described construction.

Having now fully described my invention, what I claim and desire to protect by Letters Patent is 1. A bottle cap or closure comprising a disk provided with a pouring orifice, a laterally extending upwardly inclined spout at one edge ofthe disk in front of said orifice,

a downwardlybent lip back of the inner edge of the spout and forming an inner extension of the spout and a front wall for said orifice and extending below the level of the main body of the disk, and a movable gate to open and close the orifice.

A bottle cap or closure comprising a disk having a pouring orifice located near one edge thereof, a laterally extending u wardly inclined spout projecting from tie disk in front of the orifice, the metal of the disk at opposite front corners of the orifice being notched and the metal of the disk between said notches being bent down to form a lip acting as an inner extension of the spout and adapted to engage the inner wall of the bottle neck adjacent to the latters upper edge, and a movable gate to open and close the orifice.

3. A bottle cap or closure comprising a substantially fiat disk, a spout projecting therefrom, flanges along that part of the circumference of the disk between opposite ends of the spout and adapted for engagement with the outer wall of the bottle neck, a lip back of the inner edge of the spout extending below the level of the body of the disk and adapted for engagement with the inner wall of the bottle neck, there being a. pouring orifice in the disk the front wall of which is formed by the lip, and a movable gate to open and close the orifice.

In testimony of which invent-ion, I have hereunto set my hand, at Philadelphia, on this 14th day of August, 1914.
