Specification of Letters Patent.

Patented Jan. it?. 19M.

Application led March 31, 1910. Serial No. 552,595.

To all whom it may concern:

Be it known that I, CHARLES W. Mor.- rnn'risn, a citizen of the United States, residing at l Audubon avenue, borough of Manhattan, city, county, and State of N ew Yorka have invented certain new and useful Improvements in Caps for Milk-Bottles, of which the following is a specification.

The object of the invention is to provide a very simple device which may be readily attached to and detached from bottles, or similar receptacles to normally close and seal the bottle, but being provided with a valve device which may be opened to permit the contents of the bottle to be readily poured therefrom.

Another object of the invention is to provide a bottle cap which may be clipped over the top of a. milk bottle and to provide said cap with a pouring opening, and a venting opening, a double armed valve being centrally pivoted to the cap and adapted to cover both of said openings.

Another object of the invention is to provide the cap with a pouring lip or spout by means of which the contents ofthe bottle may be properly and easily directed into areceiving receptacle.

In the drawings; Figure l is a plan view of the cap; Fig. 2 a vertical sectional view thereof on the line II-II of Fig. l; and Fig. 3 a similar view on the line IIIIII of Fig. l.

Referring to the various parts by nu- .merals, l designates the main body of the cap, the central portion 2 thereof being depressed to form an annular shoulder 3 adapted to seat against the inner edge of the bottle opening the main bod of the cap resting on the upper edge of the ottle. The depressed portion of the cap is provided at diametiically opposite points with openings 4 and 5', opening 4 being'the larger and serving as an exit for the contents of the bottle and consequently the pouring opening. vThe aperture 5 serves as a ventlng opening to the pourin permit the air to flow into the bottle during operation.'l Formed integral with the bo y lof the cap aretwo spring cliparms'G Whiclrdepend from thev cap and are ada ted to be sprungove'r an upper flange 7 of t e bottle. These clips serve to hold the cap tightly againstthe upper edgeofl the bottle, and to maintain the shoulder 3 seated on the inner edge of the bottle so vas to form D. liquid-tight jointat that point. The cap Letters Patent is:

. at a point radially in line with the pouring opening isvformed with an upwar ly and outwardly extending spout or lip 8 adapted t0 receive the liquid from the aperture 4.

Pivoted at the center of the cap 011 the upper surface thereof is a double armed valve 9 said valve being pivoted at its center and extending radially therefrom in opposite directionsone of its ends adapted to close the pouring opening L tand the other to close the vent 5. It will thus be seen that by swinging the valve away from the pouring opening the milk or other contents of the bottle may be poured from the opening 4 -by means of the spout 8 directed into a receiving-vessel. lVhen the bottle is in an upright position `the valve may be closed to prevent the entrance of air into the bottle the bottle either for the purpose of refilling the bottle or for cleaning the device. It is also clear that when one z bottle is empty the cap may be readily detached therefrom and attached to a full bottle.

This device was designed to take the placev of the ordinary temporary bottle caps which are now so largely used.

. I-Iavin thus fully described my invention what I c aim as new and desire to secure b 1. A bottle cap comprising a body portion sov serving as a closure for a bottle, 'means for detachably connecting said cap to the upper end of a bottle, said body portion being formed with an upwardly and outwardly extending spout and a depressed central portion to form a shoulder adapted to engage the inner edge of the bottle opening, said depressed portion being formed with a pouring opening radially in line Withsaid spout and a venting opening at a 'point diametri. callyl opposite said pouring opening, and

means for closing said venting opening and y pouring opening, substantially as and for the purpose described.

2. A bottle cap comprising a body portion serving as a closure for a bottle, spring clips carried thereby and adapted to secure the ing opening,`a. Valve pivoted at the center body portion to the top of the bottle, said of the depressed portion and adapted to Ioody portion being formed with an upclose both the venting opening and the pour- Wardly and outwardly extending spout and ing opening.
