Application December 11, 1953, Serial No. 397,547

2 Claims. (Cl. ZZZ-457.5)

This invention relates to dispensers for granulated substances, and more particularly to salt shakers adapted to minimize the efiect of atmospheric moisture on the salt.

Prior to the present invention,- many attempts to provide moisture-proof salt shakers employed structures de signed to seal the contents in the salt shaker from the atmosphere. In an articlesuch as a salt shaker it is practically impossible to provide an air-tight seal which will seal the contents tightly when the shaker .is not in use and yet be opened when it is desired to use the shaker. Other forms of moisture-resistant salt dispensers in which some form of a dead-air space is used to protect the salt from the moisture in the atmosphere have the disadvantage of having a narrow opening through which the salt must pass and wherein it may become, clogged.

With the foregoing in mind the principal object of the present invention is to provide a novel salt dispenser wherein the salt is effectively isolated from contact with moisture in. the atmosphere,

Another object of the present invention is to provide a novel salt dispenser in which there are no small openings which may become clogged by the salt.

Another object of the present invention is to provide a novel salt dispenser of the above-mentioned type wherein there are no projections or edges onwhich the salt may collect.

A still further object of the present invention is to provide a novel salt shaker having the advantages and characteristics setv forth which may be manufactured easily and cheaply and which is entirely efiicient and effective in operation and use.

These and other objects of the present invention and the various features and details of the operation and construction thereof are hereinafter more fully set forth and described with reference to the accompanying drawing, in which:

Fig. 1 is a view in perspective of a salt dispenser made in accordance with the present invention;

Fig. 2 is a sectional view diametrically through the dispenser shown in Fig. 1;

Fig. 3 is a perspective view partially in section of the salt container and base member of the dispenser shown in Fig. 1; and n Fig. 4 is a bottom plan view of the salt dispenser shown in Fig. 1.

The present invention comprises, essentially, a salt dispenser having a unitary container and base member in which the container is supported on the latter, open-end up, in such a manner that a large unobstructed discharge opening is provided between the bottom of the container and the base. A cover is adapted to fit over the container and be secured to the base with clearance between the top and sides of the container and the inner surface of the cover so that the salt may flow unimpeded out of the top of the container and downwardly between the container and cover, thence out through the opening in the base.

Referring more specifically to the drawing, reference numeral 10 designates, generally, a salt dispenser comprising an annular base 11 on which a salt container 12 is supported. The container 12 is supported in spaced relationship vcoaxially of the base by a diametrically arranged fin or web 13. In the present instance the container 12 has a slight taper toward its closed rounded bottom and is open at the top, and may be molded, as a unitary structure, integral with the base 11 and web 13, of a clear or colored plastic, metal, or any other suitable material.

The annular base 11 has a cylindrical upper portion 15, which is externally threaded as at 16 to receive the cover, and a relatively enlarged flange portion 17 at the bottom thereof which provides a seat for the bottom edge of the cover, hereinafter described, and also as a stand for the salt dispenser 10; The inner surface of the portion 15 of the base is cylindrical and provides a smooth surface devoid of projections or edges onwhichsalt might collect.

Asshown, the diameter of the opening 11a provided by the annular base 11 is substantially greater than the diameter of the container bottom end which it surrounds so that a large discharge or outlet for the salt is provided. in addition, the web or fin 13 has the minimum thickness required to provide the necessary support for the container 12 and may have its upper edges beveled or rounded to provide a sharp edge so that no obstruction lies in the path of discharge of the salt from the dispenser 10.

A cover 19 is provided to fit over and enclose the container 12. The lower edge portion of the cover 19 is internally threaded as at 20 for screw engagement with the threads 16 on the base 11 so that the dispenser 10 may be grasped and shaken to discharge the salt therefrom without the various parts thereof becoming detached. The inner surface of the cover 19 above the screw threads is provided with an undercut shoulder 21 which overlies the upper end edge of the cylindricalbase portion 15 so that the inner surfaces of the cover 19 and base portion 11 are flush, thus presenting a continuous smooth surface having no projections on which the salt may collect. v

Clearances 22 and 23 are provided between the sides and upper end respectively of the salt container 12 and the inner surface of the cover 19 so that the salt may escape from the container 12, flow downward between the cover 19 and the outside of the container 12 and through the opening 11a. In this connection it is to be noted that in the illustratedembodiment of the invention the cover member19 is tapered toward its closed upper end and cooperates with the oppositelytapered configuration of the container 12 to provide between said container and cover an annular discharge passage for the salt which decreases in area progressively from the outlet opening Ila in the base 11 of the dispenser inwardly or upwardly to the top of the container. By providing this discharge flow passage of decreasing area to the top of the container 12, the moisture in the atmosphere outside of the dispenser is prevented from reaching the salt in the container 12. This is so because any moisture-laden air which tends to enter the dispenser through the base opening 11a is prevented from reaching the salt in the container by the air already in the dispenser which cannot be displaced or compressed sufiiciently by the atmospheric air to permit the latter to reach the interior of the container 12. a

It 'Will be apparent that this construction provides a dead-air space which effectively isolates the salt from moisture in the atmosphere and thus maintains the salt dry at all times so that salt is readily discharged from the dispenser at all times and under all climatic condilatedtrom contact with the atmosphere.

present invention provides a novel salt shaker in 1! so that it is'possible to distinguish between salt and pepper shakers. Preferably, the button 24 is secured in a recess or cavity 25 in the closed top end of cover 19. This cavity 25 which is sealed by the mouse serves" to provide a dead-air chamber in the top of'the cover in confronting relation to the container open mlto heat transfer to andfrom the innew mrfwe of the cover top portion which overlies the end of the container.

' he an dispenser 10 is filled by unscrewing the cover I" and pouring the salt into the container 12. In cedar to dispense the salt therefrom when the cover I! isin' place, all that is necessary to do is to hold the container upright and shake 'it up. and down slightly. The be forced over the top edge of the container 12, WHY pass downward between the outer edge thereof and theeover 19 and be discharged through the opening lh'ill'ihfi base 11.

From the foregoing it will be seen that the present [provides a novel salt shaker or like dispenser there are no small openings which may become Med with salt and in which the salt is effectively iso- Furthermore,

w ltichnormal shaking of the dispenser is suflicient to bunk any, caked or large lumps of salt and allow the sell tobe removed therefrom.

lt'will be apparent, of course, that use of the shaker on dispenser is not limited to salt but may be used genorally as a dispensary for condiments and other maserials in finely divided form, and while certain embodi- W10 the present invention have been illustrated and herein, it is not intended to limit the present to such disclosures, and changes and modificaflom may be incorporated and embodied therein within the scope of the following claims.
