. when the cover or lid is opened.

Still another veryimportant object of the -inlventon is to provide a closure of the character described which is adapted to seal the container and which, further, includes means for retainingl the cover or lid in either open or closed position.

Other objects of the invention are to provide a container closure of the character set forth which will be comparatively simple in construction, strong, durable, highly eiiicient and reliable in use. compact, attractive in appearance and which may be manufactured at low cost.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawings wherein like characters of reference `3`0 designate corresponding parts throughout the several views, and whereinz. Figure 1 is a view inside elevation of a closure constructed in accordance with the present intainer.

Figure 2 is a top plan view thereof. Figure 3 is a view principally in vertical section through the closure and the container, showing the pivotcd cover open with the pouring spout 40 in operative position. v

Figure 4 is a fragmentary view in horizontal section, taken substantially on the line 4--5 of Figure 3.

Referring now to the drawings in detail, it will 45 be seen that the embodiment of the invention which has been illustrated comprises a ring I of suitable material which is adapted to be threaded on: the neck 2 oi a conventional container 3. On theupperendoithering I isaninternaltianse l. Mounted in the upper portion of the ring I is a rubber gasket or annulus l which is secured 'in position on -the top o f the container neck 2 by the flange 4.

Formed integrally with the vention, showing the ldevice moimted on a coning outwardly and downwardly therefrom is a handle 6. Projecting from the upper portion of the handle 6 is a grooved lug 1. Below the lug 1 the handle 6 has formed therein agroove or channel 8 the purpose of which will be presently set forth. l

Pivotally mounted at 3 -on the upper portion of the handle 6. is an arm III of substantially channel shaped cross section. Formed. integrally with the pivoted end of the arm I0 is a cover II in the'form of a disk. The lower side of the cover Il is provided with an annular bead or rib yI2 which is adapted to seat on the gasket 5 for sealing'the container 3 when said cover II\ is in closed position. It will be observed that the rubber gasket 5 extends inwardly from the flange t in a manner to receive the bead I2. c

Mounted longitudinally in the arm IU is a coil spring I3. One end of the coil spring I3 is engaged in the groove of the lug -'I for retention thereby. The other end of the coil spring I3 is engaged with and retained by a suitable lug It on the free or outer end of the arm I0.

Mounted on the lower side of the cover II is a pouring spout I5 of arcuate cross section. The pouring spout I5 includes a pair of integral arms I6 which are rigidly secured at I1 to the lower side of the cover II. 'I'he lower end of the pouring spout I5 is formed to provide a lip or shoulder I8 which is engageable beneath the gasket 5 when said spout is in pouring position.

It is thought that the operation of the device will be readily apparent from a consideration of the foregoing. With the cover II in closed po sition the pouring spout I5 depends from said cover into the container 3. The coil spring I3 presses the cover II downwardly thereby engaging the bead I2 with the rubber gasket 5 in a manner to seal the container 3. When it is desired to dispense the contents of the container 3 the cover II is swung upwardly to open position through the medium of the arm II).` This may be conveniently accomplished with the thumb of the hand which grips the handle 6. When the cover II is in open position the lip or shoulder I8 of the spout- I5 is engaged beneath the sealing gasket 5 in a manner to prevent the tlow of the container contents therebetween. The contents of the container may now be dispensed in an obvious manner. The groove or channel I in the upper portion of the handle I accommodates the coil spring I3 when the cover II is in open position. The spring I3 also urges the cover II upwardly when in open position in ring I and extenda manner to press the lower portion of the spout I5, with the lip or flange I8,l against the gasket S. The construction and arrangement is such that the coil spring I3 swings past dead v.center when the cover H is opened or closed. Thus, the spring I3 constitutes means for securing the cov- -er in either open or closed position.

parts may be resorted to which will fall within the scope of the invention as claimed.

What is claimed is:

A container closure o1' the class described comprising a ring for mounting on a container, a sealing gasket mounted in said ring, a cover pivotally mounted on the ring, a bead on said cover engageable with the sealing gasket, a pouring spout on the cover movable thereby to operative position and engageable with the sealing gasket when in operative position, and means for releasably securingthe cover in open or closed position.
