SHAKER FOR SALT, ETC

Application filed January 5, 1928. Serial Ito. 330,561.

Objects of this invention are to provide a shaker for salt and the like which is substantially free from the usual ditliculties re i'ulting from humidity, which permits caked alt to be loose ed and broken up without penin the shaker, which permits quick and acile cleansing of the interior, which may be made in contrasting colors with economy,

which substantially restricts the area of con- 0 tact between salt and shaker to a body portion which, while frangible, is unaffected by the salt and does not discolor or otherwise affect the salt. which has cap and base members of non-frangible material shaped to protect the intermediate frangible body from breakage, and which is generally more attracand more satisfactory in use than shakers as heretofore constructed.

For the purpose of illustration one concrete embodiment of the invention is shown in accompanying drawing, in which Fig. 1 is an elevation;

Fig. 2 is a central longitudinal section;

Fig. 3 is a similar section of the body part; and

Fig. a is a top plan View of said part.

The particular embodiment of the invention chosen for the purpose of illustration comprises a base 1, a perforated cap 2 and an intermediate body 3. vVhile the three parts may be detachably telescoped together 1 suitable way to permit separation, the f rably fits over the upper end of the nd the base into the lower end thereof, e par's preferably have threaded engagement to prevent accidental separation. As shown in the figures the threaded upper end of the base substantially iills the opening 5 in the bottom of ti e body so that the upper face of this end is substantially flush ru the lower edge of the downwardly tasmooth surface of the body and the or other contents of the body can not t not with the threads. the bottom of ti *hreaded end at the base 1 is provided with older 7 extending outwardly a distance approximately equal to the thickness of the body 3 whereby the exterior contour of the parts when threaded toget ier is substantially continuous. Likewise at the junction be- Elle tween the cap and body the two parts have substantially the same thickness and the threads are located intermediate the inner and outer peripheries with right-angle shoul ders 8 and 9 abutting the ends of the body and cap respectively so that both the inner and outer contours are substantially contin- 111,01? across the junction between the cap and or y.

The cap andbase may have any suitable design but are preferably formed in whole or in part of silver or other material which is nonfrangible. The body 3 is formed of a phenol condensation product such as bakelite or karolith or other light moulded material presenting a hard smooth surface which is not corroded by contact with salt and which will therefore not tend to freeze to the cap and base react with the salt. Thus the only part which normally contacts with the salt is unaffected by the salt and does not contaminate the salt; whereas the only portions which are normally subject to breakage are nonfrangible. Indeed, by extending the peripheries of the cap and base to maximum diameters such as shown in the drawing, the body can not contact with a flat surface such as a table or floor, when the shaker is dropped.

Another feature of the invention consists in the shape of the body whereby the interior periphery flares upwardly throughout substantially its entire length, from a minimum diameter at the bottom opening 5 to a maximum diameter at the top opening. This shape affords the following advantages: The salt, after using the shaker, falls obliquely againstthe entire inner surface of the body, thereby tending to dislodge particles adhering to the surfaces. If, after a long period of non use, the salt cakes in the body, it may be readily dislodged by an impact upon the bottom of the shaker since the flaring contour functions as it would in a mould for sand or other mass of particles. After the cake is loosened it may be easily broken up by shaking the device back and forth to cause the cake to impinge alternately against the oppositely flared body and cap. The interior of the body may be cleaned with facility by holding the body under a tap so that the water not only flows through the body, but by virtue of the aforesaid flare or taper, impinges obliquely against the entire inner surface of the body, thereby to dislodge particles adhering thereto.

From the foregoing it will be evident that notwithstanding the openings at both ends for cleaning purposes, the area of contact between salt and shaker is normally confined substantially to the body 3 of material which between the shaker and its contents being substantially confined to the non-metallic, non-corrodible molded material, while the parts subjected to impacts are relatively nonfrangible.

2. A shaker comprising a hollow body portion formed of a smooth non-corrodible nonmetallic moulded material and tapering downwardly from a large opening at the top to a small opening at the bottom, a tapered perforated metallic dispensing cap having a portion extending to a larger diameter than the said body portion, the interior contour of the shaker extending substantially continuously across the junction between the cap and body, and a metallic flaring base having a reduced end extending into and completely closing the small bottom opening of the body, whereby the area of normal contact between the shaker and its contacts is substantially confined to the non-corrodible molded material while the parts subject to impact are relatively non-frangible.

3. A shaker adapted to dispense salt or the like, comprising a hollow body formed of hard non-metallic non-corrodible molded material and having an internal smooth surface, the hollow body tapering inwardly from substantially its top to substantially its bottom, and having a recess at its bottom for the reception of a part of a base, a perforated metallic dispensing cap detachably mounted on the body at the top thereof, and a base having a reduced end extending into and completely closing the bottom recess of the hollow body, the area of normal contact
