5 Claims. 1

This invention relates to improvements in shakers for deliquescent materials, such as salt.

The primary object of this invention is the provision of .an improved salt shaker which embodies .a shaker top enclosed within a container having 'a. closure for normally excluding air and moisture except when the shaker is to be used, and embodying improved means for containing a desiccant for the purpose of maintaining low humidity within the shaker and the container.

Other objects and advantages of the invention will appear in the following detailed description.

In the accompanying drawing, forming a part of this specification, and wherein similar reference characters designate corresponding parts thruout the several views,

Figure 1 is a perspective view showing the shaker in use.

. Figure 2 is a rear elevation of the shaker.

.Figure '3 is a vertical cross sectional view taken thru the shaker on the line 33 of Fig. 2, showing theassociated features thereof.

Figure 4 is a transverse cross sectionalview taken substantially on the line 44 of Figure 2.

In the drawing, wherein for the purpose of illustration is shown but a preferred embodiment of the invention, the letter A may generally desigrlate the shaker for deliquescent materials, such as salt, which includes a main container B embodying shaker features for the deliquescent material, and means for detachably mounting therein an improved desiccant containing cartridge C.

The container B preferably includes front and rear walls It! and II, side walls I2 and I3; a bottom wall ll; closure [5 and a partition wall H. The shape of the container is not very material. In the present instance it is rectangular. The partition ll divides the interior of the container into compartments 20 and 2 l The compartment 20 is adapted to receive some deliquescent material such as salt 23. A slanting top wall 24 is provided between the front wall l and the partition wall 11, preferably integrally connected to said walls and the side walls l2 and I3, as shown. It slopes downwardly and forwardly towards the wall In and is provided with an externally screw threaded neck 21 adapted to detachably receive a shaker cap 28, as shown in Figure 3. This cap has its perforated top wall located at the same angle as the wall 24 for convenience in shaking the salt or other deliquescent material from the compartment 2|], as will be quite obvious.

The closure I is pivotally connected at 30 upon the rear wall H' of the container. It includes a top wall 35; side walls 36;' front wall 3ll'a'nd rear wall 38. The walls 36, '31 and 38 are in the same plane respectively as the side,.front and end walls of the container portion above described, and they define a space or chamber 40 adapted to receive the filler cap 28 and the upper end of the desiccant cartridge .C." The pivot connection 3D is located at the juncture of the walls I Land 38 and provided with a spring 50tonormally shut the closure, for the purpose of exeluding air and moisture. 1

A top wall 55 integrally connected with'the walls H, H, I2 and I3 is provided with an opening 56 for detachably and snugly receiving the casing 51 of the cartridge C. The latter is Preferably circularin cross section.

The cartridge casing 51 is preferably of metal and has a tapered bottom 60 which fits in a tapered socket in the bottom ofthe compartment 2|. The casing 51 is longer than the compartment 2| and includes an upper portion normally projecting above the wall 55. It iszlaterally apertured'at l0 and includes an imperforatetop wall 1|. The cartridgecasing 51 is filled with some desiccant l5, suchas silica gel to a level below the apertures 10 and the cartridge in the zone of the apertures 10 is filled with some'material "i such as glass wool, which will admitof airand moisture enteringthe cartridge casing from the compartment 40 but will prevent any possibility of the desiccant being shaken into the .compart ment lfl thru the'openings l0. I i 7 The'container B can be made of any approved material, altho plastics are presently preferred. The cartridge casing 51 is of metal so that it may be removed and the moisture dissipated from the desiccant thru evaporation. It is noted that the cartridge casing is an integral structure, since it is preferably sealed during manufacture after insertion of the desiccant and the glass wool.

It is to be noted that the space within the easing structure of the shaker, and which casing structure includes the main container and the closure is subdivided into three compartments, one of which lies above the other two.

It is within contemplation of the invention to also provide a desiccant such as silica gel in granule form of particles sufficiently large in diameter to prevent passage thru the openings of the receiver.

Various changes in the shape, size and arrangement of parts may be made to the form of invention herein shown and described without departing from the spirit of the invention or the scope of the following claims.

We claim:

1. In a shaker for deliquescent materials such as salt, the combination of a casing structure including a compartment having a, slanting top wall provided with an apertured shaker top, said casing having a second compartment, a removable cartridge in said second compartment having a desiccant therein and provided with an apertured top portion projecting from the second compartment, and a closure for the casing structure having walls for sealing off external air and moisture from the deliquescent and desiccant materials when in shut position and permittingcommunication of the enclosed atmosphere between said materials.

2. In a salt shaker the combination of a casing structure including a body portion providing a pair of compartments, one of said compartments being adapted to receive salt, said body portion having an apertured top wall for said salt com- 'partment,"a cartridge detachably mounted in the second compartment having an apertured end extending above the body portion, a desiccant in said cartridge below the apertured end, material in the upper endof'the'cartridge in the apertured zone to admit of air and'moisture passing therethru to the desiccant and excluding the desiccant from 'contact-with-the apertures of said upper end, and a self -closing 'cover having walls for shutting oi? the apertured end ofthe cartridge and the apertured wall ofthe salt compartment from external atmosphere.

3. In a'shaker for deliquescent material'such as salt and the like, a casing structure comprising a body and self-closing imperforate cover, means sub-dividing the casing-into three'compartments, one-of which lies substantially above the other two, an apertured wall construction for one "of the'said other two compartments-the compartment with the apertured wall construction being'adaptedto receive a; deliquescent comminuted materialya' removable cartridge in the second of said other two compartmentshaving a desiccant therein, said cartridge having an opening'therein communicating 'withthe top compartment whereby to maintain low-humidity in the top compartment and in the deliquescent material compartment.

4. In a shaken for deliquescent "material such as salt and the like,- a casing structure comprising a main container and acover, the main container being subdivided into two'compartments, a removable desiccant receiving cartridge mounted in one compartment having apertures therein, the other compartment being adapted to receive a deliquescent material and having a top wall structure provided with apertures therein, said cover having a chamber therein above the container and defining a free space exposed to the apertures of the cartridge and the said apertured wall of the deliquescent receiving compartment when the cover is closed, said cover being imperforate so as to seal ofi the casing when it is shut.

'5. In .a shaker for deliquescent material such as'salt and the like, a casing structure comprising a main container and a cover, the main container being subdivided into two compartments, 9. desiccant disposed in one compartment, the other compartment having a top wall structure provided with apertures therein, and said other compartment being adapted to receive a deliquescent material, said cover having a chamber therein above the container and defining a free spaceexposed to the apertures of said wall and to the desiccant when the coveris closed, said cover beingimperforate so as to seal off the casing when it is-shut.
