It* is, vh''Cvev,"'t'"*beu understood the invention is not limited--tolthe specific tails: of construction ar-i'd-v'A arrangement shown', 'but may embody various changes and modifica- '.tions within the scope of the invention.

In this drawing:

Fig. 1 is a section through the device showing :it in the normal closed or sealed position;

Fig. 2 is a partial side elevation and partial section of the device and also showing `the method of 1115;

Fig. 3 is a top plan view;

Fig. 4 is a section substantially :of Fig. 2, and

Fig.v 5 is a side or elevational view of the closure device.

The device comprises the usual glass body or bottle I forming a container for the granular material, such as salt H, and of course this may be of any desired shape. At its upper end itis on line 4 4 provided with a reduced neck portion I2 which is threaded as indicated at I3 to receive a similarly threaded cap I4 with a bre or rubber washer, I between the upper end of the neck and a shoulder I6 to seal the container when the cap is in place. The cap may also be of any suitable shape, but is preferably tapered at its upper portion as indicated at I'I, and it may be made of any suitable material, such, for example, as This cap is open at its ing 20. It also has any desired number of open-` ings 2I around this opening 20 for passage of the salt. v

The closure comprises a rubber or similar mem--` ber 22 preferably in the form of a disc provided on its under side with a resilient shank 23 pro- K vided with an enlarged head 24. When in position on the cap the shank passes through the opening with the retaining head 24 at the under side of the partition I9. This head 24 is eref l I,rel 1n as"tnjs1k-is trtenedl'hasterrds to shorten due to its resiliency, it Will automatii cally hold the disc 22 of the closure on thetop of the cap to seal the outlet opening IB, and thus y maintain the device moisture proof and prevent the salt from absorbing moisture from the air. The disc is `larger than the top of the cap-so as to overhang it.-

In use, the operator merely places a thumb or finger on, the top of the closure at one side edge,

as indicated for example in Fig. 2, and presses y downwardly on this edge. This tips the disc or closure as indicated and removes it from one side of the opening I8, so that the operator by then tipping or turning the container to an upsidedown position, can shake the salt from thecontainer, it passing through the ,openings 2I and the top opening I8. As soon as the closure 22 is released, the stretched resilient neck 23,auto matically swings it back into closed position to seal the opening I8 in the cap. Should it be found that the best rubber composition for the closure 22 is not stiff or rigid enough to maintain its shape, a thin disc 26 of metal, plastic, liber or other suitable more rigid material than the rubber may be molded within this closure to give it greater stiffness or rigidity.

Itwill be evident from the above that thisis cluding a container with a relatively small discharge opening at the top surrounded by a relatively narrow rim, a support inwardly of the discharge opening permitting passage of the material to the discharge opening, a closure for the discharge opening on the outer side thereof and including a resilient rubber under side resting on the rim, a resilient elastic shank connected to and ,extendingv from the under side of?` the closure through the discharge opening and connecting the closure with the support, said shank being under stress so that it automatically retains the under side of the closure against the rim over the discharge opening, and said closure including a portion extending outwardly lbeyond the rim of the discharge opening so as to over hang this rim and which overhang is free to move downwardly by pressure on its top surface sof that it forms a finger grip which on downward pressure rocks the shank and closure toward one side rof the rim of the discharge opening as a r pivot to shift the opposite side of 'the closure away from said rim to permit passage ofy the" material from the container. 1

2. A shaker' for salt and similar material including a container witha discharge opening` at the top surroundedby a narrow rim, a support inwardly of the discharge opening, a closure and attached shank for the discharge opening includ? ing a resilient yieldable under side resting on'said rim on Vthe outer side of the discharge opening,

vby pressure on its top surface to tip the closure abouty the rim on one side of the discharge opening .as a pivot and shift the opposite portion of the closure outwardly away from the rim and the discharge opening to permit passage of the material from the container, a resilient elastic shank passing through the discharge opening connected at its opposite ends to the closure and the support, and said shank being under stress so that it automatically returnsy the closure to the closed position and retains ita-againstY the rim to ,close thedischarge opening when pressure on the nger grip is released.
