SHKE AND POUR DEVICE Fiied oct. 2s, 195e United States Patent Oiiice SHAKE ANDY POUR DEVICE Application October 26, 1956, Serial No. 618,534 z claims.V `(cl. 222-555) This invention relates generally to shaker and pouring spout tops for merchandising and dispensing containers for granular material like salt. y

, More particularly this application is a continuation-inpart of my copending applications S.N. 558,515 led January 1l, 1956, Shaker Top With Pouring Spout, now Patent No. 2,777,615, and S.N. 501,952 tiled April 18, 1955, Shaker Top, now Patent No. 2,777,616, of which application S.N. 558,515 is a contiuuation-inpart.

It is a primary object of this invention to provide an improved combined shaker and pouring top means for a container for granular material.

It is a second object to provide a two part molded plastic dispensing means for a container for granular material in which one part of said twopart means is a wall element of said container. i

It is a third object to provide av twopart molded plastic dispensing means for a container for granular `material in which part of one part of said two part means is adapted to be inserted into a hole formed in a wall element of said container and in which said one part is secured in said hole by thermal deformation of said part of said one part which is inserted through said hole.

It is a fourth object to provide a two part molded plastic dispensing means for a container for granular material in which part of one part of said` two` part'means is adapted to be inserted into a hole formed in a wall element of said container and in which said one part is secured in said hole by mechanical deformation of said part of said one part which is inserted through said hole.

It is a fifth object to provide a two part molded plastic dispensing means for a container for granular material in which part of one part of said two part means is adapted to be inserted into a hole formed in a wall element of said container and in which said one part is secured in said hole by an elastic ring resiliently girdling the outer surface of said one part.

It is a sixth object to provide a salt dispensing container for general use having a two part top structure consisting of a stator vand a rotor rotationally secured in the stator and with a single relatively large hole through the stator, a similar relatively large hole through the rotor and a group of relatively smaller holes through the rotor angularly spaced from the larger hole through the rotor so that the rotor can be rotated in the stator to a desired one of three positions in which no salt can be dispensed from the container or the container can be iilled or emptied through the registered large holes in the stator and rotor, or salt can be shaken from the container through the large hole in the stator and the group of smaller holes in the rotor registered therewith.

How these and other objects are attained is explained in the following description referring to the attached drawing in which Fig. l is a view in a side elevation and partial section of a table salt dispenser of this invention.

Fig. 7 is a fragmental view in partial section of a salt container in which the top insert of Fig. 2 is mechanically secured by an elastic clamping ring.

Like numerals of reference refer to like several figures of the drawing.

Referring now `to the drawing, Fig. 2 showsbasically a two part molded plastic dispensing means for a container of granular material, the dispensing means being essentially similar to that disclosed and claimed in `my above noted Patent No. 2,777,616 except that the present device provides a group of` shaker holes and ajlarger parts in the pouring hole while the prior device provided two sets of shaker holes and no pouring hole. The present device is an improvement for the reason that one set of shaker holes is all that can be Yused and a pouring hole provides an opening either for filling or empting the container.

As shown in Figs. 2, 3, 4, and 5 the dispensing means 11 consists of a molded .plastic stator 12 and a molded plastic rotor 13, the stator comprising a generally cylindrical side band 14 topped by an annular top flange, 15,`

overhanging band 14 both inwardly and outwardly thereof and a flat bottom 16 through which are formed theA two holes 17 and 18 separated by an arcuateweb`19 formed with a detent recess 29 on the `side ofhole 18.`

.Therotor 13 comprises a generally disk like `piece of molded plastic formed on one side with a groupof salt` shaker holes 21 therethrough and on the other side with a filling or pouring hole 22. `On its underside rotor 13 is formed with dependent detent `23 positioned inhole 18 to rub on the semi-circular edge thereof and land in recess 20 when holes 21 and 22 are farthest `from their positions of registry with hole 17 of stator 12. When detent 23 is at either of its limit positions along the edge of hole 1S either shaker holes 21 or pouring holes 22 will be in registry with hole 17 of stator 12. Depressions 24 are sunk into the top of rotor 13 to form linger recesses` to receive the fingers to press either way on upstanding rib 25 to turn rotor 13 to its closed center position or either of its end positions of shake or pour respectively.

Because the plastic material of which both the rotor 13 and stator 12 are molded has the characteristic of returning to its previous shape after cold deformation, rotor 13 is chamfered at its bottom outer edge 26 to lead rotor 13 into the top opening of stator 12 as the two parts are press assembled with the outer circumference of rotor 13 underhanging the inner circumference of flange 15 of stator 12. Thus it is seen that rotor 13 is rotatably secured in stator 12 by the upper surface of bottom 16 of stator 12, the inner surface of band 14 of stator 12 and the inner and lower surfaces of flange 15 of stator 12.

As seen in Figs. 5, 6 and 7 the general type of dispensing means 11 shown in detail in Figs. 2, 3 and 4 is designed to be inserted into a hole formed for the purpose in the pressed paper top 27 glued to a pressed paper open ended paper container 28 and secured in top 27 by any desirable means. A most satisfactory way for securing insert 11 into top 27 is to press a plurality of heated rods upwardly around insert 11 to contact insert 11 along ledge 29 while means are provided to prevent the upward movement of insert 11. In this manner a number of Patented `June 2, 1959.,

3 spaced permanently deformed upset spots 30 are formed in insert 11 to clamp around the edge of top 27 and tix insert 11 permanently in top 27.

Another Way I have used and found satisfactory to hold the insert in the container ltop is illustrated in Fig. 6in,

which is shown insert 111 having the outer cylindrical surface of band 114 provided with longitudinally extending spaced barbs 115 formed thereon. When the insert 111 is pressed through the hole of top 27 in container 28 it is seen that barbs 115 will engage top 27 to prevent rotation of insert 111 in top 27. Then a ring of approximately the same inside diameter as barbs 115 is pressed upwardly on the end of barbs 115 while insert 111 is held against upward movement. In this way barbs 115 are mechanically deformed somewhat as shown at 130 and insert 111 is secured permanently in position without use of heat.

Still another way I have found satisfactory and sometimes desirable to hold insert 11 in to 27 is shown in Fig. 7 where a tight but slightly resilient flat ring or washer 40 is pressed upwardly over the outer surface of band 14 of insert 11 and top 27 is rmly clamped as shown.

Since the designV of shaking and pouring top insert for a salt dispensing container is provided with pouring hole 22 which can also be used for a filling hole, this type of insert is desirable for use with smaller containers which can be refilled and used on the table or on picnics. And since the container in this case will be of smaller diameter the top 27 of the container may be dispensed with and the insert 211 adapted to close the open end of container 228 as shown in Fig, l with the outer edge of annular top ange 215 of stator 212 formed downwardly to receive the top edge of container 228 between cylindrical side band 214 and the cylindrical dependingl outer rim of annular top flange 215 of stator 212. Then a heated roller is rolled around the outer edge of rim of annular top ange 215 and insert 211 is permanently fixed to container 228.

It is thus seen that I have invented as here disclosed a new'and simple form of two piece plastic top insert for a salt dispensing container which without the addition of any parts provides an additional filling or emptying spout for the container and is an improvement over my previous inventions in this eld.

Also it is see-n that in addition to the two methods previously'disclosed and used by me I have invented and ticing the invention and explained the operation thereof,

I claim:

1. A dispensing and closing insert for a hole in a wall of a merchandising and dispensing container for granular material, said insert comprisingl a one piece molded plastic stator and a one piece molded plastic rotor, said stator comprising a cylindrical side band, a planar annular top flange formed on one end of said side band to overhang said side band radially inwardly and outwardly thereof, the outwardly extending portion of said topy flange being adapted to be bent into engagement with the rim of said` container, a at bottom member and means securing said at bottom member at its periphery to said side band at the other end thereof, said at bottom member being formed with a dispensing hole therethrough and said rotor being rotatably secured to said stator with the outer edge of said rotor conned between the inner surface of said cylindrical side band, the inner surface of the inwardly overhan'ging part of said top flange and the inner surface of said bottom member, said rotor being formed with a dispensing hole therethrough, and both said stator and said rotor being formed with rotation limit means operable to lirnitthe rotation of said rotor'- within said stator in one direction to a position of registration of said holes in said stator and said rotor.

2. The insert of claim 1 characterized by having the top surfaces of said stator and said rotor substantially coplanar. l
