INVENTOR w se i f ATTORNEYS Patented` June .6,- 1939 UNITED STATES PATENT; OFFICE- zusam CONTAINER. cmsm curas o. Nelson, Bellevue. in. Application .fury za, 193s, semi No. 222,024 3 cams. (Cl. zis-m) Thisinvention relates to closures for containers, and its general object is to provide a closure in the forms of a cap forv use with all types of open top c ntainers, such as milk bottles, jars,

drinking c ps and glasses, etc., the cap being formed from elastic material to be' stretched about the open top of the container to provide a. leakproof connection therewith, and the cap has a normally closed valved controlled opening therein 'for dispensing the contents ofthe container therefrom, the valve being moved to open f position manually or by the contents, when the `aontainer is tilted for pouring the contents there- 'rom. A further object is to provide a container closure or cap of the character set forth, that includes. apouring spout integral therewith, and the cap is simple in construction, inexpensive to manufacture and extremely emcient in operation, m use and service.

IThis invention also consists in certain other.

featuresfof construction and in the combination and arrangement ofthe several parts, to be hereinafter fully described, illustrated in the accom.- u panymg drawing and specifically pointed out in the appended claims.

lIn describing the invention in detail, reference will be had to the accompanying drawing wheref in like characters denote like 'or corresponding I0 parts vthroughout the several views, and in' which: Figure 1 is a fragmentary vertical sectional- 4 l,Referring to the drawing m detain-lt wm be noted that I have illustrated my closure or` capv vas being applied to a milk bottle, but as-previouslyindicated, it is to be made-in all sizes for use a with all types of open top containers, including jars, drinking cups and glasses, etc, f

The cap is molded or otherwise formed from elastic material such as rubber, to provide a Arela-V tively thick'disklike wall 4i having an annular 50 flange formed on and depending from-the pe- 'riphery thereof to provide askirt 2 which is shownas being directed .inwardly from its juncture with thewau ljto its lower-edge, mais r4beveled accordingly,` soas` to. set up a grippingl leng agement with the'llp of milk bottle or edge portion of other containers, as wil1-be ai parent.

The top wall I is 'provided with a V-shaped slit 3 having itsapex terminating adjacent the edge of the wall, and the slit 3 .not pnly provides a pouring opening but a lip or flap valvel 4 for closing the opening. It will be noted that the walls Aof Vthe slit are arranged at an inward angle of approximately sixty degrees which tends to form a seal between the valve 4 and its opening.

as well as to prevent the valvefron'i dropping be- .low its seat into the container, as will be apparent upon inspection of Figure 3.

Formed on and rising from the top wall i is a pouring spout 5 of substantially V-shaped. formation to follow the shape of the opening in the wall I, and is inade up of converging walls for that purpose which increase in height from their rear ends to their forward or apex ends, so that their upper edges are arranged at an upward inclination toward their apex ends., and with their rear ends merging into the top wall, while the forward ends are joined, with the vresult it will be seen that the outlet of the spout .is .pointed and that feature coupled with the .converging walls will cause the contents of the container to be poured in'a thin stream, when the container is tilted for that purpose.

lrising therefrom a knob 6 providing a handle therefor, so that the valve can be manuallyv opened if desired or found necessary to do so. However, when the container is tilted, for pouring thev contents therefrom, in most instances the action oi' gravity combined with the weight of the contents will cause the valve 4 to automatically open, and due to the elastic nature of the valve, it will be automatically closed when the knobis `released or when the container is restored to its uprightposition. a

lIt is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent. It is'to be understood that changes may be inaden the construction and in the combination and arrangement of .the several parts, provided that such changes fa1l.within the scope of the appended claims. f

What I claim is:

1. A closure for av container and being formed from elastic "material lto `provide a disklike top wall, a flange forined on and depending from the periphery of the top wall and providing av skirt for securing the closure to the container, said top .wall being split in V-shaped formation mally closing the opening and held accordingly lbythe inherent nature of the elastic material,

said valve being movable to open position by the contents .of the container when the latter is tilted for pouring the contents therefrom and a pouringspout formed on'and rising from the top wall and following the shape of the opening.

2. A' closure for a container and vbeing formed from elastic material vto provlde'a disklike `top wall, a flange formed on and depending from the periphery of the top wall and providing a skirt for securing the closure to the container, said skirt being tapered toward its lower end and beveled accordingly to set up a gripping engagement with the container, said top wall being split to provide a pouring opening and a valve vnormally closing the opening and held accordingly bythe inherent nature of the elastic material, the walls of the split being disposed at an inward angle to set up a sealing action between the valve and its opening and to prevent the valve from dropping into the container, said valve being movableto open position by the contents of the cn- 25 tainer'when' the latter is tilted for pouring the contents therefrom, a pouring spout formed on and rising from the top wall and following the shape of the opening, and said pouring spout being made up of converging walls having inclined upper edges to'provide a .pointed outer end for the spout. v v v 3. A closure for a container'and being formed -from elastic materialto provide a'top wall, a

iiange formed on and depending from the 'outer edges of the top 'wall and 'providing a skirt for securing the closure to the container, said top Wall being split in V-shaped 'formation to `provide a' pouring opening and avalve normally closingthe opening and held accordingly by the inherent nature of the elastic'material, the walls of the slit being disposed-at an inward angle to its opening and to prevent thevvalve from dropping into the container, said valve being movable vto open position by the contentso! the container f when the latter is tilted for pouring the contents 'set up a.sealing action between thevalve and f
