Patented Mar. 2, 1943 UNITED STATES FATE OFFICE DISPENSING CAP AND CLOSURE FOR CONTAINERS 11 Claims.

This invention relates to dispensing caps and closures for containers of honey, syrup, catsup, and other viscous liquids that are inherently difficult to dispense in the usual manner. This invention is an improvement on my co-pending application Serial No. 170,781 filed October 25, 1937, which became Patent No. 2,229,303 January 21, 1941.

One of the objects of this invention is to provide means for holding and guiding th slide Plate from the lower or inner side thus removing the necessity for external lugs or guides which rub on the upper surface of the slide plate and detracts from the appearance of the dispenser by Wearing ofl the plating or polish.

Another object is to provide the quality appeal of a cast thumb-piece and yet retain the advantage of a closure assembly that is readily removable from the cap for cleaning purposes and quickly attached thereto, thus reducing the assembly cost.

This invention also provides a seat for the spring portion of the closure assembly which combines the advantages of ready accessibility for cleaning with a spaciousness which precludes the danger of the spring becoming rusted or corroded therein as may occur in a more restricted seat.

A still further object is to provide a closure assembly with the slide plate of a non-corrosive material and a spring to actuate the slide plate of a more resilient material and yet retain the advantage of removability.

The above mentioned advantages and many others can be readily comprehended from the description and aided by the accompanying drawing, wherein Figure 1 is a side View, in vertical cross section, of the invention attached to the container, part of which is shown;

Figure 2 is a cross section on the line A-A of Figure 1;

Figure 3 is a plan view of Figure 1;

Figure 4 is a side view, partly in cross section, of a modified form;

Figure 5 is another modified form. showing .a side view with the cap and handle cast integral with the container;

Figure 6 is a view of Figure 5 looking in line with the handle and spout.

The dispensing cap, shown in Figure 1 as a die casting, has a top 1 having an annular dependent skirt 8. This skirt has provisions, such as threads therein, for attaching the cap to a container 9. The top 1 is continued on another plane forming the top plate II].

This raised portion of the top has a vent hole II, a pouring spout l2 covered with a side plate or slidable closure I3, and a slot l5 wherein slides a clip M. This clip is attached to the lower or inner sid of the slide plate I3 and guides the slide plate in its sliding movement, it also prevents lateral movement of the slide plate. The slide plate is preferably made of a non-corrosive material, such as stainless steel, or a molded plastic, of which the cap and closure may also be cast. Acid containing materials can then be dispensed without harm to the dispensing device. This clip has a pair of wings l6 pressing against the top plate I0 on both sides of the slot I5 thus pulling the slide plate firmly against the upper surface of top plate I0 and closing the pouring spout. The slide plate has a continuation forming a thumb-piece H with flanges Hi to give it a more substantial appearance. Extending downwardly from the slide plate is a spring I9 the lower end of which rests on the bottom of a V-shaped groove 20. One side of this groove is formed by the dependent skirt 8, the other side 2| by a raised portion of the bottom plate 22 having flanges 23, 23 which with the bottom plate terminate in a handle 24. These flanges close the ends of the V-shaped groove thus retaining the lower end of the spring [9 therein. The sides of the V-shaped groove are preferably spaced at an angle approximately equal to the angle generated by the movement of the spring 19 when the slide plate is retracted. The sides of the V shaped groove then act as stops preventing excessive movement of the slide plate l3. The above reference characters refer to similar parts in all fi ures.

I find that by using a V-shaped groove instead of a slot, that the spring [9 can be thicker and less resilient, and thus react with greater force. The distortion of the spring when the slide plate is retracted is distributed along its entire length and part of the slide plate. In the two modifications I show other means for guiding the slide plate as I do not wish to be limited in the manner in which my novel closure assembly is used in dispensing devices of this type. The closure assembly consists of the slide plate, the thumb-piece, and the actuating spring or the lower'end of the thumb-piece I1 and in Figure 1, the clip 14.

In Figure 4 I have shown one of a pair of lugs 25 which guide the slide plate in the usual manner. The rivet 26 which connects the spring 19 and. the thumb-piece I1, is extended and. normally closes the vent hole I l.

The modification shown in Figures 5 and 6 has the dispensing cap and the handle cast integrally with the container. The guiding means, bail 21, is a wire bent into a C shape, having its ends inserted in the depressions 28. There are two projections 29, 29 on each side of the container between which the ends of the bail lie thus preventing movement thereof, when the slide plate is retracted. The ends of the V shaped groove are open and the bottom is curved to facilitate molding. To prevent sideward movement of the lower end of the thumb-piece IT, or the spring I9 if the closure assembly shown in Figures 1 or 4 is used, the end is curved as shown at 30 to conform with the curve at the bottom of the V shaped groove. The spring l9 passes through a slot in the thumb-piece IT.

The closure assembly shown in Figures 1, 4, or 5 is interchangeable with either of the other two dispensing caps by: removing or adding the clip I4, adding a curve at the end of the spring I9, changing the location of the vent hole 1 i, and /or other minor alterations apparent to anyone skilled in the art.

All of the dispensers shown in the drawing are operated by grasping the handle 24, tipping into a pouring position anddepressing the thumbpiece ll, this in turn retracts the slide plate i3 uncovering the pouring spout i2. In Figures 1 and 5 the slide plate, when open, arches over the vent hole thus allowing the admittance of air. When the thumb-piece i released the spring rapidly propels the slide plate forward into a closed position cutting oil the flow from the pouringspout.

Any of the closure assemblies shown can be readily removed from or attached to the dispensing caps.
