A. scHAlcH BALL-TYPE FLUID APPLICATOR PACKAGE 2 Sheets-Sheet 2 Filed Aug. 6, 1958 INVENTOR. filzaazlafi dy/ax/ Unite- This invention relates to an improved fluid applicator package and, more particularly, to that type of applicator package characterized by the provision of a rotatable applicating member or device which functions as a fluid applicator by transferring a film of fluid from the applicator package onto a selected surface, against which the applicating member is brought into rolling contact.

A principal object of this invention is to provide an improved fluid applicator package in which there is embodied an improved applicator assembly possessing a novel structure which facilitates the mounting of a rotatable applicating member on the dispensing end of a container, and which operates to promote a smooth and uniform application of fluid substances packaged within the container.

Another object of this invention is to provide an applicator assembly having the above-described characteristics, in which the applicating member is positioned at least in part within the confines of the dispensing end of the container and retained in such position by a resilient retaining fitment which permits the applicating member to be rotated during the application of such fluid substances without becoming dislodged from assembly with the container.

A further object of this invention is the provision of a cap or closure which is threadably engageable with the neck of a container on which an applicator assembly of the above-described characteristics has been attached, and which functions in such manner that when it is threaded onto the container neck it urges the retaining fitment into sealing engagement with the surface of the applicating member to thereby isolate the fluid contents within the container and prevent leakage of such contents when the applicator is not in use.

A still further object of this invention is to provide a container having a neck portion provided with a ball seat formed in such manner as to accommodate a portion of the applicating member in a loosely retained applicating position within the neck portion of the container.

A still further object of this invention is to provide a fluid applicator package in which there is embodied an improved combination of a fluid dispensing container, an applicating member, a resilient retaining fitment for the applicating member, and a cap or closure for capping the container, wherein the container has a neck portion in which a portion of the applicating member may be seated for rotatable movement, and wherein the retaining fitment retains the applicating member in such position, while permitting a minor portion or minor diameter chordal portion of the applicating member to protrude through the retaining fitment for applicating purposes, and wherein the closure, when tightly attached to the container, will enclose the applicating member and retaining fitment and will urge the retaining fitment into sealing engagement with the surface of the applicating member.

A particular object of the present invention is the provision of a liquid applicator package having the combined provision of an applicating member, a container having a neck portion within which the applicating member may be seated, a retaining fitment for the loose retention of the applicating member on said neck portion, and a closure for capping the neck portion when the applicating member is not being utilized, wherein said closure, when tightly capping said neck portion, will cause a portion of said retaining fitment to be resiliently displaced froma normal applicating position located exteriorly of said neck portion to a position located within the confines of said neck portion and sealingly engaging the surface of said applicating member, and to this end providing the container neck portion with a tapered rim portion, and the closure with a projection cooperating with said rim, to facilitate the displacement of the retaining fitment.

Another particular object of this invention is the provision of an improved liquid applicator package having the last-mentioned characteristics, wherein the retaining fitment is of resilient construction and will return to its normal position proximately spaced from the surface of the ball applicator when the closure is unloosened from the container, such position corresponding to the position which it occupies when the package is being utilized for applicating purposes.

The specific nature of this invention, as well as other objects and advantages thereof, will become apparent to those skilled in the art from the following detailed description, taken in conjunction with the annexed sheets of drawings on which, by way of preferred example only, are illustrated the preferred embodiments of this invention.

On the drawings:

FIG. 7 is a sectional view taken along the plane 77 in FIG. 6.

With reference to FIG. 1, there is illustrated a liquid applicator package comprising, generally: a fluid dispensing container 10 having a neck portion 10a; a spherically shaped ball applicator 11 of suitable diameter to permit it to seat loosely Within the neck portion; a resilient annular retaining fitment 12 which snaps over the end of the neck portion to maintain the ball applicator in assembled position; and a closure 13 which threadably attaches to the exterior surface of the neck portion and cooperates with the neck portion in such manner as to cause the retaining fitment 12 to sealingly engage the surface of the ball applicator when the applicator is not in use. However, as illustrated in FIG. 3, when the closure 13 is detached from the neck portion ltla, such as for the purpose of utilizing the applicator package, the resilient nature of the retaining fitment 12 causes it to disengage from the surface of the ball applicator '11 and resume a normal position proximately spaced therefrom, in order to permit the ball applicator to be universally rowhich is externally threaded, as at b, for attachment of the closure 13. At the dispensing end or mouth 10c of the container, the neck portion defines an inwardly tapered rim 10d, which slopes downward into the interior of the neck portion to form a frusto-conical configura- .tion. At its outer edge, the rim, 10d merges into an annular retaining bead 10a encircling the rim, and at its inner edge the rim merges with the interior surface 10 of theneck portion. Spaced axially inwardly from the tapered rim ltld, the interior surface lilf'converges to form at least one integral internal projection ltig, restricting the opening in the neck portion to a diameter somewhat less than that of the ball applicator 1 1 and thereby restricting the latter against inwarddi'splacement from the opening in the neckportion.

103 are shown, and these projections provide a seat upon which the ball applicator may be retained and universally rotated. The spacing of these projections relative to the tapered rim 10d is such that the ball applicator 11, when seated thereon, will occupy 'a position in which a major portion of the ball applicator will rest within the confinesof the neck portion ltlrcand a minor portion or segment thereof will protrude outwardly from the rim in order to enable the ball applicator to be In FIG. 2, four such projections brought into direct rolling contact. with and furnish V fluid to the surface to which application is desired;

The ball applicator 11, with which the fluid contents 7 from the container are applied, defines a generally spherical configuration and is provided with a relatively smooth surface finish capable of permitting the ball applicator to be rolled in contact with a surface such as the sensitive human skin-without causing undue irritation. Ma-

terials such as glass, plastic, or metal appear to be the most favorable materials from which to fabricate such an applicator.

tainer neck portion :100 or otherwise removably attached as by providing it and the neck portion with snap-on means. integrally formed in the interior closed end surface of thefclosure 13, there is an annular deflection rib 13:; which is shaped to coincide with the upper surface 12 of the retaining fitment at a location proximately overlying the inner .edge of the tapered rim 10d of the container neck portion. The presence of the deflection rib 13b permits the closure, when threadably engaged with the neck portion 10a of the container, to engage the Web portion 120 of the retaining fitment and flex it downward over the tapered rim 10d so that the circular sealing surface 12e is pressed into sealing engagement with the surface of the ball applicator 11 to form a seal located within or interiorly of the neck portion 114M, substantially as shown in FIG. 1, to prevent leakage and inhibit evaporation of the fluid substance within the container during periods when the applicator is not being used.

As illustrated inFlG. 3, the resilient and flexible nature of the retaining, fitment 12 causes the annular web portion 121; and sealing surface 12a to return to their normal proximately spaced relationship relative to the surface of the ball applicator 1 1 when the closure is removedpreparatory to application of the fluid contents by the ball applicator.

An applicator assembly such as that just described affords a novel construction inwhich the retaining fitment is characterized by a highly simplified and eco- Furthermore, the overall length of the applicator package is materially shortened by'placi'ng the ball applicator Within the neck portion of the container, rather than over the top of'the neck portion as in most of the more conventional types of ballapplicator assemblies. Nevertheless, a fluid applicator package having the aforementioned'construction may 'be manipulated with exceptional ease and permits the fluid contents of the containerrto be rolled onto the desiredsurface in the form of a smooth and uniform film of liquid. 1 7

It will, of course, be understood that various details of construction may be modified throughout a wide range Without departing from the principles of this invention, and it is,'the'refore, not the purpose'to limit the patent granted hereon otherwise than necessitated by the scope of the appended claims.

V embodiments illustrated'respectively in FIGS, 5, 6 and portion and surrounds-the ball-applicator 11 at the mouth e 1 00 of the container. Extending throughthe center of 1 the web portion 120, there is' a central opening-12d which is defined by a circular sealing surface 12e, which is taported to generally conform to'thesurface configuration V I of the ball applicator '11 -As illustrated, the central vopening 1201 is of such size as to permit the ininor diameter' chordal portion l ra of the ball applicator to protrude "7 havebeen added herein.

Referring to FlG, 5, it will e observed that a fluid dispensing container 20, similar'in external appearance tothe dispensing container 10, previouslydescribed, is

form' ed with the'interior surface 265 of the'reduced diameter neck pdrtionZiia defining a smooth bore communicating with the interior of the container. 7 The necessity 10f providing a restricted area within the interior of the neck portion 201:; such as the projections 10g in the neck portionof container 10, shown in FIGS. l-4, is obviated .in'the present embodiment by virtue of the'particularishape andconstruction of the applicah ing device 21 with which the containers contents are applied, and which is to be next described.

The applicating device 21 is preferably fabricated from the same type of materials as applicating ball 11 and has a spherically shaped body portion 21a seated Within the mouth of the bore defined in the dispensing end 200 of the container neck portion 29a, and is supported for rotational movement in such position by laterally extending supporting members such as cylindrical pins 21b, which gravitationally rest upon the rim 20d of the dispensing end 20c and are free to shift on the surface of said rim in response to movement of the applicating device 21 in contact with the surface to which the containers contents are to be applied. The pins 21b are preferably formed as an integral part of the applicating ball 21 and extend outwardly from diametrically opposite sides thereof. When the applicating device 21 is supported in the foregoing manner, a segment of the body portion 21a of the applicating device protrudes axially outward from the dispensing end 200 of the container 2!), as at 2.10, for convenient unrestricted contact with the surface to which the contents of the container are intended to be applied.

Considerable variability in the movement of the ap. plicating device 21 i provided, since the applicating device 21 is free to rotate simultaneously or separately about either of two different axes disposed in perpendicular relation to each other and corresponding respectively to the longitudinal axis A of the pins or rollers 21b and axis B, which is situated in substantially coaxial alignment with the longitudinal axis of the container neck portion 20a. As a result, a biaxial rotational movement of the applicating device 21 is afforded, which promotes relatively unrestricted manipulation thereof during application and which facilitates a smooth and uniform transferal of the containers contents.

As illustrated, the applicating device 21 is retained in assembled position by a resilient retaining fitment 22, which is substantially the same in structure and function as the retaining fitment 12 described previously with respect to the embodiment shown in FIGS. 1 and 3. However, in the present embodiment the annular web portion 220 of the fitment 22 overlies the rim 20d of the container 20 in spaced relationship to define an annular internal pocket, as at 2211, within which the pins or alternatively rollers 21b of the applicating device are free to slide, if in the form of pins, or roll or rotate, if in the form of rollers on the rim 20d of the container without substantial obstruction.

As illustrated in another embodiment shown in FIGS. 6 and 7, the interior surface of the container neck portion 30a is modified somewhat and defines a radial upwardly facing shoulder 39b having a smooth continuous surface surrounding the bore of the neck portion and on which the pins or rollers 21b of the applicating device 21 are gravitationally supported for biaxial rotation in substantially the same manner as previously described with respect to the embodiment shown in FIG. 5. The shoulder Silb may be provided by forming a recess in the interior surface of the neck portion 30a, as shown, or may be otherwise provided, such as for example, by forming an inwardly projecting continuous ledge thereon (not shown). Also, as illustrated, the fitment may be identical in shape with the fitment 12 shown in FIGS. 1-4.

In other respects the structure and function of the embodiments shown in FIGS. 5-7 are substantially identical with the embodiment shown in FIGS. l-4, and as illustrated in FIG. 6, the closure 13 when threadably attached to the neck portion of the container resiliently depresses the inner periphery of the fitment into sealing contact with the spherically shaped body portion of the applicating device 21.

Among other advantages, the embodiments shown in FIGS. 5-7, afford a reduction in the preciseness ordi narily required in the fabrication of an applicating ball, such as shown in FIGS. 1-4. Additionally, since the rotation of the applicating device is restricted to a biaxial rotational motion rather than universal rotational motion, the applicating device is readily suited to more economical fabricating techniques involving the use of split molds, and the like, for the molding of the applicating device, where as such techniques have been ordinarily unfavorable for molding the conventional ballshaped applicating members, such as shown in FIGS. 14.

By showing and describing several specific constructions embodying the present invention, it is not intended to limit the invention, except as required by the scope of the following claims, since it will be apparent to those skilled in the art that various changes and modifications may be made in the particular form, construction and arrangement of parts without departing from the scope and intendment of the invention and without sacrificing the advantages thereof.
