1966 J. M. AMBURGEY DISPENSING CLOSURE WITH SLIDE Filed Dec. 8, 1964 NIH,

JAMES MILTON AMBURGEY INVENTOR.

ATTORNEY United States Patent 3,294,294 DISPENSING CLGSURE WITH SLIDE James Milton Amburgey, Kendall Park, NJ., assignor to Colgate-Palmolive Company, New York, N.Y., a corporation of Delaware Filed Dec. 8, 1964, Ser. No. 416,689 7 Claims. (Cl. 222-525) This invention relates to a cap capable of being attached to a container for dispensing liquid. More particularly, this invention relates to a push-pull cap which does not impede the flow of liquid from a container.

Broadly, this invention contemplates a dispensing closure for a container capable of holding a liquid and comprising an elastomeric plastic top wall having an upwardly extending projection defining a passage extending through said extension and top wall, a stirrup having two diametrically positioned narrow arms connected at one end to the top wall adjacent the inner end of said passage and at the other end to a cross piece, a plug on said cross piece axially aligned with and extending toward said passage, an elastomeric plastic slider slidably mounted in said passage in fluid-tight relation thereto, said slider haying therethrough a discharge channel adapted to mate with and be closed by said plug when said slider is positioned thereon, an enlargement on said slider at the outer end thereof to facilitate moving it outwardly off said plug and cooperative means in said passage and on the slider to limit normal outward movement of the slider after the inner end thereof is slid clear of said plug.

In the drawing, FIGURE 1 is a plan view of a cap embodying an invention:

FIGURE 2 is a vertical cross-sectional view along the line 22 of FIGURE 1;

FIGURE 3 is a plan-sectional view taken along the line 3--3 of FIGURE 2; and

FIGURE 4 is a cross-sectional View taken along the line 44 of FIGURE 2.

The cap comprises a side wall 4 and a top Wall 6. Depending from the top wall is a stirrup, generally indicated as 8. This stirrup 8 has two diametrically positioned narrow arms 10 and 12, which are attached to the top wall 6. A cross piece 20 is connected to the end of each arm remote from the top wall 6. A plug 22 is intermediate to, and attached to, the cross piece 20 and extends upward toward the top wall 6.

The top wall 6 includes an upwardly extending projection or sleeve 24 which defines a passage through the top wall 6 and sleeve 24. The passage is axially aligned with the plug 22. An elastomeric plastic slider 26 havinig a discharge channel 28 therethrough is slidably disposed within the passage of the sleeve 24 in a fluid-tight manner. The discharge channel 28 of the slider '26 is axially aligned with and is capable of receiving in a fluid-tight manner the plug 22, so that when the slider is pushed down, the plug 22 will project, in a fluid-tight manner, into the discharge channel 28 of the slider 26 and will thus seal off said channel 28 from a container.

The slider 26 includes a rim 30 which cooperates with the shoulder 32 of the sleeve 24 to serve as a cooperative stoppiing means to limit the normal outward movement of the slider 26 after the slider 26 is clear of the plug 22.

The end of the slider 26 opposite the plug has a concave enlargement 40 which serves to limit the amount of drippage from the container after product has been discharged therefrom and after the container is returned to an upright position.

In order to assure a fluid-tight fit between the slider 26 and the plug 22, as well as the slider 26 and the sleeve 24, the clearance between said slider 26 and said sleeve 24, as well as said slider 26 and said plug 22, at the point-of contact of each with the slider is from about 0.003 to about 0.006 inch.

The cap includes a ring 42 which depends from the top -wall 6 and surrounds the stirrup 8. This ring 42 is flexible and is capable of being deformed to eflect a seal between the cap and a container when the cap is attached thereto.

The clearance between the ring 42 and any part of the stirrup 8 is at least 0.002 inch so that when the cap is attached to the container the ring 42 will deform to provide said seal without contacting the stirrup 8. In this manner, there is .no possibility that the ring 42 will put pressure on the stirrup 8 and deform it thereby disturbing the alignment of the plug 22 with the discharge channel 28.

In order to provide the stirrup 8 with the desired strength and flexibility, the narrow arms 10 and 12 have a wall thickness of at least 0.09 inch and the cross piece 20 has a wall thickness of at least 0.14 inch.

The cap 2 may be attached to a container in any suitable manner and preferably by providing threads 44 on the inside surface of the side wall to mate with external threads on the bottleneck (not shown) of a container.

The cap may be molded in any suitable manner, such as by injection molding. It is preferable that the cap be manufactured from polyethylene having a density of from about 0.920 to about 0.940 because it has been found that polyethylene havinig a density within such a range provides a cap with the necessary flexibility and allows for the necessary slidability. However, the cap may also be molded from other materials which have a suitable flexibility and allow the necessary slidability.

When it is desired to dispense product from the container to which the cap is attached, the concave enlargement 40 is grasped and pulled up until the rim 30 of the slider 26 contacts the shoulder 32 of the sleeve 24. In this manner, the slider 26 is disengaged from the plug 22, as shown in FIGURE 2, without removing the slider 26 from the cap '27. The bottle is then tilted so that liquid may freely flow through the discharge channel 28 and be dispensed at the outer,vconcave-shaped enlargement 40 of the slider 26. After the desired amount of liquid has been dispensed, the container is returned to an upright position and the slider 26 is pushed down, thereby causing the plug 22 to enter the discharge channel 28 of the slider 26 (FIGURE 4) in a fluid-tight manner and prevent undesired discharge of contents of the container regardless of the angle at which the bottle is held.

It has been found that the aforedescribed cap is particularly advantageous in that the structure of the stirrup and surrounding area does not impede the flow of liquid from a container. This is particularly advantageous when such a cap is used in conjunction with a container which holds a fairly viscous liquid which is to be dispensed.

While this invention has been described in terms of a preferred embodiment, the invention is not to be construed as limited except as set forth in the following claims.

I claim:
