Nov. 22, 1960 R. NYDEN VALVE!) CLOSURES FOR coummnas Filed Sept. 9, 1958 FIGJ INVENTOR ROBE R T N YDE N ATTORNEY United States Patent VALVED CLOSURES FOR CONTAINERS Robert Nyden, 109 Castle Ridge Road, Manhasset, N.Y.

Filed Sept. 9, 1958, Ser. No. 759,985

10 Claims. (Cl. 239-327) This invention relates to a valved closure for containers of resilient material, such as polyethylene for containing liquids, wherein the closure is adjustably mounted in the container whereby in one position of the closure the =liquid is sealed in the container and in the other position of the closure the liquid is discharged in a spray from the container by external pressure on the container, such as squeezing the container in the hand of the user.

It is an object of the invention to provide a one-piece valved closure which is inexpensive to manufacture and easy to assemble in the container.

Another object of the invention is to provide a onepiece valved closure which is mountable in an integral part of a container or in a closure cap removably mounted on the container.

It is another object of the invention to provide the valved closure and the container of a material which will form a liquid tight sealing fit between the valved closure and the container.

Another object of the invention is to arrange the container and a discharge orifice of the valved closure so that the spray will be discharged at a right angle to the vertical axis of the container.

A further object of the invention is to arrange the valved closure with an air passage from the container to the liquid receiving portion of said closure to assure the formation of a fine spray.

Other objects and advantages of the invention will be set forth in the detailed description of the invention.

In the drawing accompanying and forming a part of this application:

Figure l is a top view of the valved closure;

Figure 2 is an elevational view of the valved closure showing a slot therein;

Figure 3 is an elevational view in section of the upper portion of a container closed by a closure cap and the valved closure mounted in said closure cap and actuated to open position;

Figure 4 is a sectional view taken on the line 4-4 of Figure 3 looking in the direction of the arrows;

Figure 5 is a view similar to Figure 3 showing the valved closure in closed position;

Figure 5 is a sectional view, on an enlarged scale, of the upper portion of a container arranged with an integral discharge member and showing the valved closure in open position; and

Figure 7 is an elevational view of the structure shown in Figure 6 and looking at the right hand side of Figure 6.

In Figures 3, 4 and 5, the invention is shown in combination with a container 8 of resilient material, such as polyethylene, having an annular neck 9 extending from the exterior of the top wall of the container. The neck 9 of the container is closed by a closure cap of resilient material, such as polyethylene, comprising a skirt portion 11 having a liquid-tight sliding fit in the neck 9 and a top wall arranged with an annular flange to abut the top edge of the neck 9, as shown at 11. The closure cap is arranged with a tubular discharge member in the top wall thereof comprising a first portion 12 extending from the exterior of said top wall and arranged with an inturned lip 13 having a beveled outer face forming a sharp edge with the opening in the lip, as shown at 14. A second portion 15 of the discharge member is extended from the interior of the top wall of the closure cap into the closure cap in spaced relation to the skirt portion 10. The second portion 15 is shown as terminating within the skirt portion 10 but it may extend beyond said skirt portion. The under face of the inturned lip 13 extends in a substantially horizontal plane, as indicated at 16 in Figure 5.

The opening in the inturned lip 13 is closed by a valved closure of resilient material, such as polyethylene, comprising a stern portion 17 of uniform diameter throughout its length having a liquid-tight sliding fit in the inturned lip 13 and a knob 18 integral with one end of the stem portion to abut the inturned lip and limit the downward sliding movement of the stern portion in the tubular discharge member 12-16. The under face of the knob 18 is beveled corresponding to the beveled outer face of the inturned lip 13, as shown at 19, to seal the lip when the stem 17 is in its innermost position in the discharge member 124.6. The periphery of the knob 18 is serrated, as at 20, to facilitate gripping the knob and actuating the valved closure. The opposite end of the stem 17 is arranged with a horizontal shoulder 21 formed by an integral inverted truncated conical portion 22 having a sliding fit in the discharge member 12-16 at the base of said truncated portion.

The valved closure is arranged to discharge the contents of the container 8 in a fine spray at a right angle to the inturned lip 13 by providing an axial recess 23 in the stem portion 17 and in the truncated conical portion 22 opening at the truncated end of said portion 22 and terminating in an intermediate section of the stem portion 17. The terminating end of the recess 23 is of conical shape, as shown at 24, and a section of the recess below said conical end 24 is of less diameter than the major portion of said recess, as shown at 25. One end portion of a discharge tube 27 is inserted into the major portion of the recess 23 with said end abutting the shoulder formed between the major portion of the recess 23 and the reduced section 25 so that the tube is spaced from the conical end 24 of the recess and forms a mixing chamber. As usual in this type of container, the opposite end of the tube 27 is extended to the bottom of the container. A slot 28 is provided in the stem portion 17 and in the truncated conical portion 22 to extend longitudinally of and to the recess 23 and the reduced section 25. The end wall of the slot 28 terminating in the stem portion 17 extends in line with the angle of inclination of the conical end 24, as shown at 29, and forms with the exterior of the stem portion a sharp edge 26. The recess 23 including the reduced section 25 and the conical end 24 and the slot 28 extend above the shoulder 21 a distance greater than the thickness of the inturned lip 13, so that in the outermost position of the valved closure, the end wall 29 and the sharp edge 26 of the slot 28 will be positioned above the sharp edge 14 and provide a discharge orifice, as shown at 30 in Figure 3. The conical end 24 and the end wall 29 of the slot 28 are spaced from the knob 18 so that said conical end and the end wall of the slot are below the lip 13 in the innermost position of the valved closure and the discharge member is sealed by the lip 13 and the stem portion, as shown in Figure 5.

In operation, the valved closure 17-29 is pulled upwardly from the discharge member 12-16 until said movement is stopped by the shoulder 21 abutting the inner face 16 of the lip 13. Then the contents of the container 8 is placed under pressure by squeezing the container, as

indicated by a thumb in Figure 3. The pressure will force the contents up the tube 2-7 and force the air in the container above the contents up through the slot 28 to intermingle or mix with the contents of the container in the mixing chamber formed by the inner end-of the tube 27, the reduced section 25, the conical end 24 and the slot end 29 and form a fine spray which is discharged in a horizontal plane or at a right angle to the vertical axis of the container, as indicated at 31in Figure 3, due to the sharpedges 14 and 26. The sharp edge 14 wilf also prevent an accumulation of the contents on the exterior of the discharge member. To facilitate discharging the spray in the desired direction, the top of the. knob 18 is arranged with an index, such as an' arrow, as indicated at 32 in Figures 1 and 2. I The point of the arrow is in vertical alignment with the slot 28, as shown in Figure 2. The knob 18 is turned in the. desired direction of discharge of the spray.

To close the discharge orifice 30 and seal the container 8, the valved closure is pushed down until said movement is arrested by the beveled under face 19 of the knob 18 abutting the beveled outer face of the lip 13.

In Figures 6 and 7, there is shown another method of applying the valved closure to a dilferent type of container wherein the usual closure cap is omitted. .Said container comprises a body 33 of resilient material, such as polyethylene, having the tubular discharge member embodied in the top wall of the container and consisting of a first portion 34 integral with and extending from the exterior of the container top wall and arranged with an inturned lip 35 at the outer end of said first portion provided with a beveled outer face arranged with a sharp edge 36 and a horizontal inner face 37. A second portion 38 of the discharge member is extended from the interior of the container top wall into the container. The tubular discharge member 33 38 is of the same structure as the tubular discharge member 12-16 shown in Figures 3 to 5, inclusive, except that in Figures 3 to 5, inclusive, said discharge member is integral with a container closure cap, and inFigur es 6 and 7, the discharge member is integral with the container top wall.

In Figures 6 and 7, the valved closure is'the same as the valved closure shown in Figures 1 to 5, inclusive, and cooperates with the tubular discharge member 3438 in the same manner as it does with the tubular discharge member 1216. Like reference numerals denote like parts of the valved closure mail of the figures.

The valved closure 17-29 is readily assembled in the discharge member 1216 or 34-38 by firstinserting the tube 27 in the recess 23 and then passing the tube 27 through the opening in the inturned lip 13 or 35; The shape of the truncated portion 22 and resiliency of said truncated portion and the inturned lip 13 or 35 facilitate the forcing of the shoulder 21 past the inturned lip. 13 or 35. The truncatedportion 22 will also prevent damaging the sharp edge 14 or 36 Having thus describedmy invention, I claim:
