10 Claims. (Cl. 222-498) This invention relates to a combination dispensing device and closure for fluid containers of various kinds, and is particularly useful in connection with containers from which fluids are to be intermittently discharged or poured, the device being effective selectively to direct the discharge of the fluid in a desired direction and therafter to reseal or close the container after a desired amount of the fluid has been poured or discharged from the container through the device.

One of the objects of the present invention is to provide an inexpensive and easily mass-produced dispensing and closure device of the character just stated which may be quickly applied to fluid containers, reagent bottles, cigarette lighter fluid cans, and many other kinds of containers of the type having relatively narrow discharge mouths. Another object of the invention is to provide a combination closure and dispensing device that may be interchangeably applied to fluid containers, the device being easily removed from an empty container and installed on a full container. Still another object of the invention is to provide a dispensing and closure device of this kind that may be easily molded in twopiece form of resiliently flexible organic plastic or resin such as polyethylene or the like, the device being fluid-tight in its closed condition and without exteriorly exposed joints or relatively movable mating surfaces likely to permit leakage of the fluid.

These and other objects and advantages of the present invention will be apparent from the following description of a preferred embodiment of a combination dispensing device and closure embodying the features of the present invention, taken with the accompanying drawings wherein:

Fig. 1 is a fragmentary side elevational view of a bottle, can or other container, having an upwardly extending neck on which a combination dispensing device and closure of the present invention is mounted;

Fig. 2 is a vertical cross-section, on an enlarged scale, taken through the dispensing device and through the uppermost extremity of the neck of the container, the dispensing device being shown in its closed condition;

Fig. 3 is a View similar to Fig. 2 but showing the container tilted to a dispensing position, with the dispensing spout of the present device being flexed laterally to an open or pouring condition by the finger shown in broken lines, the contents of the container being free to flow outwardly through the spout when the spout is in the relative position illustrated;

Fig. 4 is a top plan view of a seat member seen in Figs. 2 and 3, the lower or inner end of the spout being shown in a seated position on this member'in Fig. 2, and in a displaced position with respect thereto in Fig. 3, thereby permitting flow of the fluid from the container outwardly through the spout; and

ice

The present dispenser and closure is shown in the drawings mounted upon a hollow can, bottle or other container 10 having an upwardly or outwardly extending neck 11 terminating in a mouth 12. A plug 13 covers this mouth, the plug being of collar-like construction having a downwardly extending annular collar 14 fitted in fluid-tight engagement with the inner walls of the mouth 12 and having an integral circular disk-like portion 15 extending across the exterior of the mouth with a radially extending. circular shoulder 16 provided thereon and seated on the outer lip 17 of the neck. The disk-like portion of the plug has an axially disposed saucer-shaped seat 18 formed integrally therewith on its upper or outer surface, the perimeter 19 of the seat being raised with respect to the adjacent upper or outer surface of the disk.

A generally cylindrical, cup-shaped cap 20 is fitted over the plug 13 and has a downwardly extending skirt 21 provided with a circular inner groove 22 which is received upon the outer periphery of the shoulder 16 of the plug in fluid-tight engagement, the lower portion of the skirt 21 being received upon and closely fitted about the exterior of the neck 11 below the shoulder 16 of the plug. The upper or outermost portion of the skirt 21 with respect to the neck 11 is of reduced thickness and is turned radially inwardly where it merges integrally with a resiliently flexible outer end wall 23 of the cap, the end wall curving downwardly and then upwardly to provide a circular corrugation 24 therein that increases the flexibility of the wall. This outer end wall of the cap is spaced outwardly with respect to the outer surface of the disk-like portion 15 of the plug 13 and with respect to the seat 18 thereon, to provide a cavity 25 therebetween, the disk being provided with a plurality of openings 26 located about the saucer-shaped seat 18 through which fluid from the interior of the container 10 may flow freely into the cavity at any time the container is tilted, as shown in Fig. 3.

Integrally with the flexible outer end wall 23, at its axial center, there is provided a substantially rigid spout 27 having an outer portion 28 extending exteriorly of the end wall and having a shorter inner portion 29 extending interiorly of the wall, the inner extremity 30 of the inner portion 29 of the spout being rounded, as at 30, so as to cooperate with and to be seated upon the seat 18 to close an axial passage 31 that extends through the spout 27 from end to end.

The cap 20, including its outer end wall and the spout 27, is preferably molded as a single, integral piece, and may be of any suitable synthetic organic resin that is both resilient and flexible by nature, polyethylene being an example. The natural resilience of the outer wall 23 and its tendency to remain in the shape shown in Fig. 2, tends to retain the spout 27 in its axial position with the rounded inner extremity 30 of the spout seated on the seat 18. The inner end portion 2% of the spout is slightly longer than the normal free distance between the inner surface of the center of the outer wall 23 and the seat 18, so that when the inner extremity of the spout is seated upon the seat 18, the outer wall is flexed slightly outwardly in an axial direction, and its resilience therefore causes the inner extremity of the spout to bear against the seat and thereby insure elfective sealing of the inner end of the passage 31. It will be seen, particularly in Fig. 2, that the contents of the container are eifective- 1y sealed when the spout is in its axial position, discharge of the contents from the cavity 25 being prevented by the closing of the passage 31.

When it is desired to pour from the container, the container is tipped to a position corresponding to that shown in Fig. 3, whereby the contents of the container will flow through the openings 26 in the plug 13 and into the cavity 25. At the same time, the exterior end portion 28 of the spout 27 'is moved laterally of the cap by the finger, as shown in Fig. 3. This lateral movement of the spout may be made in any radial direction with respect to the cap, and it causes the resiliently flexible outer end wall 23 to be flexed as shown inFig. 3, thereby causing the inner extremity 30 of the spout to be displaced laterally in a radial direction off of the seat 18 and to .be snapped across the upwardly extendingperimeter 19 thereof, whereupon the perimeter of the seat will retain the spout in its displaced position. In this displaced position the inner end of the passage 31 is open ,for free discharge of the fluid contents from the cavity 25 and thus from the container itself. When a .desired amount of the contents have been discharged, the spout is returned to its original axial position by the finger, the inner end of ,the spout again snapping across the upstanding lip or perimeter 19 .of the seat and returning to its original seated position, thereby sealing the passage 31 against further discharge ,of fluid from the cavity 25 and from the interior of the container.

- From the foregoing description, it will be understood that the exteriorportionZS of the spout 27 serves not only ,as a lever for operating the valving arrangement for opening and closing the passage 31 of the spout, but also serves as a means for directing the discharge of the contents in a desired direction, this being particularly desirable, for example, when the combination dispensing device and closure is employed upon ,containers for such fluids as inflammable cigarette lighter fluids and the like.

A modified form of the invention is shown in Fig; 5, wherein the assembly is identical to that shown inFigs. l to 4, inclusive, except for the fact that the central portion of the disk-like element ,15 of the plug 13' is thinner than the disk-like portion 15 of the plug 13 shown in Figs. land 3. The plug, in each instance, maybe molded of the same material as the cap, that is, of a resiliently flexible synthetic organic resin such as polyethylene or the like. In such materials the flexibility of the item molded will depend, in part, upon the thickness of its walls. The provision ofadisk-like portion 15',for the plug 13 of less thickness than that of the plug 13 shown inFig. 2,.renders the diskelike portionlSflexible, thereby causing the seat 18 formed on the outer surface thereof to be moved or depressed in an axialdirection when the inner extremityfii) of the 'innerportion 29. of the spout 27 is moved across the upstanding rimor perimeter 19 of the seat, as indicated bythe solid and broken lines in'Fig. '5. In the embodiment of the invention vshown in Fig. '5, the pressure of the innerextremityof the spout upon the seat, when that end'is seated upon the seat in sealing position, is preferably produced bothby the resilience of the outer end Wall 23 of the cap and by the resilience of the disk like portion '15 of the plug $13, thereby producing efiective and efficient sealingof the inner end of the passage '31. The provision of'res ilience in the disk-like portionlS of thepluglii' in the embodiment of the invention shown in Fig.5 also tends to reduce the amount of wear on the upstanding lipor'perirneter 19 of 'the'seat, and upon-the inner extremity 30 of the spout, caused 'by sliding movement of the latter over the former. This tends to increase'the effectivelife of the assembly.

It-will be notedgthat the presentdispenser and closure presents a pleasingsymmetrical appearance when it is in its normal or closed condition, the spout 27 "being axially disposed at this timeand the resiliency of the outer end wall, as well as the coactionbetween the s eat '18 a d the innermost end of the spout, tending'to re'tain the spout in its closed position, thereby making accidental opening of the closure most unlikely. At the same-hm? however, m VmQ 0 th $P to 9 posltl-on is easily accomplish d by the fing i1 ,sPout acfirlg as a leverin .the. displacement ofits low r; endi r l Furthermore, when the .spout has been moved to it open position, the upstanding periphery of the seat acts against the inner'end of the spout (Figs. 3 and 5) 'to retain the spout in its open position so that constant pressure of the finger on the spout during pouring is not required. Returning movement of the spout to its closed position is accomplished .merely by flipping the spout from its open position toward its closed position, the resilience of the outer .end wall 23 of the cap 20 and the curvature of the seat causing the spout automatically to be carried into its .fully closed position once the inner end of the spouthas been moved across the upstanding lip or perimeter .19 .of the seat.

It will also be noted that in mounting the dispenser upon acontainer,--the plug 13 or 13' may first be mounted on the mouth of-the container and the cap 20 thereafter slipped over the plug and the container neck in the position shown in the drawing, the resilience of the walls of the cap .beingsuch as to permit receipt of the shoulder 16 of the .plug into the circular groove 22 in the walls. Alternately, ,the plug may first be inserted into the cap and then the entire assembly maybe slipped onto the container neck as seen in the drawing. In any event, it will be appreciated that the assembly may be pulled oil the neck of an empty container and placed upon a fullcontainer whenever desired.

Theforegoing description has ,been given for clearness of understanding only, and no unnecessary limitations should be impliedtherefrom, for it will be apparent to those skilled in .the art that various changes may be made in theform andconstruction of the present dispens ing and closure device without ,departingvfrom the spirit and scope of the appended claims.
