FLUID DISPENSING BALL APPLICATOR Filed may 23, 1956 INVENTOR United States Patent FLUID DISPENSING BALL APPLICATOR Edward J. Holler, Jr., Toledo, Ohio, assignor to Owens- ]Jlinois Glass Company, a corporation of Ohio Application May 23, 1956, Serial No. 586,770 Claims. (Cl. --132.7)

This invention relates generally to an improved liquid dispensing package, and more particularly to an improved ball-type applicator and closure assembly for a liquid dispensing container.

An object of the present invention is the provision of a liquid dispensing package characterized by a ball-type applicator assembly, which permits the liquid contents of said package to be applied upon a selected surface in a smooth and uniform manner by the simple expedient of rolling the applicator lightly in contact with said surface.

Another object of the present invention is the provisionof a supporting fitment of unit construction for a ball applicator, simple in design, and capable of maintaining said ball applicator in secure assembled and spaced rela-' tionship relative to a liquid dispensing container.

Another object of the present invention is the provision of a ball applicator assembly characterized in part by a ball having a resiliently deformable construction.

A particular object of the present invention is the provision of a ball-type applicator assembly comprising; a resiliently deformable ball applicator, a supporting fitment for said applicator, and a threaded closure for a dispensing container which is superimposable over said applicator and fitment, wherein said closure will cause said applicator to deform and mutually seal with said fitment as said closure is threadably secured to said container, and wherein upon removal of said closure from said container said seal will be broken, and said ball will resiliently resume its normal configuration and applicating position.

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 sheet of drawings on which, by way of preferred example only, are illustrated the various embodiments of this invention.

On the drawings:

Fig. 1 is a sectional elevational view in central section of the neck portion of a container, together with an improved ball-type applicator assembly and closure therefore; showing the functional aspect of the assembly and closure in its relative closed and assembled relationship.

Fig. 2 is a view similar to Fig. l, but showing the functional aspect of the applicator assembly after the closure has been partially removed.

Fig. 3 is a sectional view taken substantially along the line 3-3 in Fig. 2, the applicator ball being omitted for clarity of illustration.

Fig. 4 is a view similar to Fig. 3, but showing a modified form of the invention embodied in Figs. 1-3.

With reference to Fig. 2, there is illustrated the neck portion 10 of a conventional container suitable for retaining a liquid therein. The neck 10 has a generally cylindrical configuration, and define a dispensing opening 10a, illustrated in Fig. 1, extending axially therethrough and communicating with the hollow interior of the container. Integrally formed on the dispensing end of the neck 10, there is an outwardly protruding retaining lip 10b. Axially inward of the retaining lip. 10b an enlarged outer diameter portion 10c defines conventional external threads 10d.

A spherical ball 11, which may be constructed from plastic, rubber, or other suitable resiliently deformable material, is also provided for rolling liquid which may be dispensed from the neck 10 onto a selected surface, such as the skin of the human body. Preferably, the exterior surface of the ball 11 should have a relatively smooth and uniform outer surface substantially free from any sharp parting line or mold seam. To reduce material cost, this ball 11 preferably has a hollow construction, and may be fabricated from conventional blow molding. methods Well known to those skilled in the art. The use of a resilient plastic or rubber material will provide the ball 11, under proper fabricating procedures, with an applicating surface which may be rolled over the skin of the human body without discomfort and without the necessity of providing the surface of the ball 11 with an expensive ground and polished finish.

To maintain the ball 11 in an assembled and elevated dispensing relationship relative to the dispensing opening 10a, there is provided an annular ball fitment 12 which may be molded from plastic, rubber, metal, or other suit able material having similar properties. Formed on one end of the fitment 12, there is a hollow neck engageable end 12a which is suitably shaped to slip snugly over the neck 10, and be retained thereon by an interior recess 12d defined within said neck engageable end 12a, which is engageable wtih the retaining lip 10!) in a snap-fit relationship. The opposite end of the fitment 12, or outer end 12b, terminates in an inwardly projecting annular retaining lip 12e which defines a central orifice 12g communicating with the interior of the fitment 12. Interspaced between the ends 12a and 1212, there is an annular perforate partition 12] which projects into the interior of the fitment 12, and cooperates with the retaining lip 12e to define a ball socket 12c therebetween. As illlustrated in Fig. 3, the partition 121 has a centrally defined opening 12 and a group of spaced marginal ducts 12k extending obliquely therethrough. Although, four such ducts 12k are illustrated in Fig. 3, it is quite obvious that one such duct 12]: may be sufficient depending, in some measure, upon the viscosity of the liquid to be applied.

The upper surface 121 of the partition 12 is inclined radially toward the central axis of the fitment 12 and serves as a seat for the ball 11. It is also obvious that the configuration of the partition 12 may be altered considerably without departing materially from the intendment of this invention, and one such modification is represented in Fig. 4, wherein the annular unit construction shown in Fig. 3, is replaced by a group of spaced lugs 12h projecting radially into the interior of the fitment 12.

The ball 11, which functions as the applicator, is diametrically larger than the orifice 12g and may be deformed sufficiently by merely compressing the ball 11 to permit insertion thereof through the orifice 12g and into the ball socket 120. After the ball 11 has been thus introduced into the ball socket 12c the compressive force may be released; whereupon, the ball 11 will resiliently return to its normal spherical shape and be retained in socketed relationship with the ball socket 120. The ball socket 12c is so located with respect to the outer end 12b of the fitment 12 that a minor portion 11a of the ball 11 will protrude therefrom and define an applicator surface. However, the remainder of the ball 11, or the major portion 11b, will be nestably retained within the ball socket for free rotatable movement.

In this assembled position, the ball 11 is ready for applying the liquid contents of the container by merely inverting the container and rolling the minor portion 11a of the ball 11 in contact with the surface to be coated. When the. container is thus inverted the ball 11 wil1 aeeaeeo gravitationally shift into contact with the retaining lip He and prevent passage of the liquid through the orifice 12g until the minor portion 11a is brought into contact with the surface to be coated. After such contact however, a slight pressure exerted upon the minor portion 11a as its being rolled will be sufficient to lift the ball 11 out of contact with the retaining lip 12a, and permit the liquid flowing through the ducts 12k to be transferred from the surface of the ball 11 onto the surface to be coated in a smooth and uniform manner. Although, the ball 11 has a deformable construction, the slight pressure necessary to shift the ball 11 away from the orifice during the application of the liquid contents will not be sufiicient to deform the ball 11, to such an extent, as to interfere wtih the free and even application of the liquid. However, a substantially increased pressure upon the ball 11 will cause it to distort and restrict the amount of liquid transferred. Thus, even if excessive pressure should be applied to the ball 11, no objectionable excessive quantities of liquid will be dispensed. This feature is quite advantageous when and if the applicator falls into the hands of children unfamiliar with its usage.

A closure 13 having a generally conventional configuration is also provided for isolating the assembled ball 11 and fitment 12, as well as the liquid contents of the container, from the atmosphere during periods of nonuse. This closure 13 may be molded from glass, plastic, or other suitable material, and is internally threaded with conventional "threads 13a which are threadably engageable with the threads d externally formed on the container neck 10. As illustrated in Fig. 1, the closed end portion 13b, of the closure 13, is spaced the requisite distance from the threads 13a to permit the closed end 13b to depress the ball 11 as the closure 13 is threadably engaged with the neck 10. When the applicator surface, or minor portion 11a, is depressed in this manner the ball 11 will be compressed between the closure 13 and the partition 12 and distend laterally into peripheral sealing contact with an annular sealing area 12m of the fitment 12. As illustrated in Fig. 2, the resilient nature of the ball 11 will cause it to rapidly resume its normal spherical shape as the closure 13 is removed from the container, and thereby permit immediate use of the applicator upon complete removal of the closure 13.

It is to be noted, when the closure 13 deforms the ball 11 into sealing contact with the fitment 12 a double seal is provided, namely; an inner peripheral seal between the ball 11 and the fitment 12, and an outer seal between the threadably engaged portions of the closure 13 and the container neck 10. This double seal is particularly advantageous when the applicator is used for dispensing such liquids as perfumes and colognes, which in addition to having properties which cause them to evaporate readily, in many instances, are quite expensive. However, the aforedescribed applicator is not limited to use with such materials and is readily adaptable to the more viscid type of liquids and emulsions such as hand 10- tions, deodorant creams, cosmetic creams, and other similar preparations. In fact, the wide variety of liquids with which this improved applicator assembly may be utilized constitutes one of its distinct advantages.

A particular advantage of the present invention resides in the character of the novel ball applicator, which may be formed from resilient materials, such as rubber or plastic, having properties rendering the surface of the ball applicator non-abrasive to the skin of the human body without the necessity of finishing the applicator surface with an expensive ground and polished finish.

Another object of the present invention resides in the deformable character of the ball 11 which renders it readily adaptable to a ball structure having a hollow interior, thereby presenting a light weight ball applicator accompanied by a considerable saving in material cost.

Another advantage of this invention resides in the simple design of the ball 11, fitment 12 and the closure 13, which permits these parts to be rapidly molded by conventional methods well known to those skilled in the art.

Another distinct advantage of the present invention resides in the overall structure of this invention which permits the component parts to be fabricated from materials such as plastic, or rubber which are generally more resistant to chemical attack than most metals of comparable cost, while still providing a substantially rigid and durable assemblage of the component parts.

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