BALL APFLICATOR HAVING SHIF TABLE BALL SUPPORT Filed July 19, 1956 INVENTOR /laawiaw/ex/ ATTOR Y5 United States Patent BALL APPLICATOR HAVING SHIFTABLE BALL SUPPORT Wilbur A. Schaich, Maumee, Ohio, assignor to Owens- Illinois Glass Company, a corporation of Ohio Application July 19, 1956, Serial No. 598,828

is Claims. c1. 15-1325 This invention relates to a ball-type applicator particularly adaptable to the application of deodorants, perfumes and similar cosmetics to the skin or clothing.

The employment of ball applicators 'in the cosmetic field is not new. Previous applicators have generally embodied a plastic retaining fitment for mounting the ball in dispensing relationship to the opening of a container, and a cooperating closure or cap which, when applied, effects a seal between the retaining fitment and the ball to prevent leakage of the cosmetic from the container. Some prior constructions have generally relied upon a lateral compression of the retaining fitment into sealing engagement with the ball to elfect the seal. Such seal is difficult to produce and maintain. In other constructions, the applicating pressure exerted upon the ball during use would tend to force the ball into sealing contact with the Wall of the fitment and thereby limit the flow of cosmetic material.

Accordingly, it is an object of this invention to provide an improved ball-type cosmetic applicator.

A particular object of this invention is to provide an improved retaining fitment for a ball applicator which is susceptible to limited axial movement with respect to the container to shift between a dispensing position and sealing position relative to the ball.

' A further object of the invention is to provide a ballapplicator construction wherein the pressure imposed upon the ball in the course of applying cosmetics has no effect upon the fiow of cosmetic from the container.

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, two embodiments of this invention are illustrated.

On the sheet of drawings:

Fig. 1 is a fragmentary vertical sectional view through a ball-type dispensing package embodying this invention, with the closure or cap of the package shown in its closed position.

Fig. 2 is a view similar to Fig. 1, but illustrating the closure or cap in a partially opened position.

Fig. 3 is a vertical sectional view of a modified form of retaining fitment embodying this invention.

Numeral represents a container, for deodorants, perfumes or similar cosmetics, having a discharge opening 10a. Around the rim of such discharge opening, there are provided a series of grooves or recesses 10b for a purpose to be hereinafter described. immediately surrounding the opening 10a, the container 10 is provided with a radial retaining lip 10c and then with an outwardly tapering section 10d which communicates with a larger diameter threaded portion 10a. A shoulder 10g is formed at the juncture of tapered portion 10d and threaded portion 10e.

A substantially rigid dispensing ball 11 is provided having a diameter in excess of the container opening 10a and adapted to seat upon the rim of container open- Patented Nov. 24, 1959 ing 10a. A retaining fitment 12 of a resilient plastic material, such as polyethylene, is provided having top ball pocket portion 12a which terminates in a sealing rim 12b of lesser diameter than ball 11 and adapted to engage the ball 11 in sealing relationship.

The other end 120 of fitment 12 is shaped to cooperate with the exterior of container 10 to permit a limited degree of axial movement of fitment 12 relative. to such container. Thus the fitment 12 includes an internal annular groove 12g adapted to be snapped into assembled relationship with container lip 10c and, groove 12g is of slightly greater axial length than the lip as to permit limited axial movement of the fitment 12 relative to container 10. In effect, the radial under surface 10 of lip 10c cooperates with radial bottom surface 12 of fitment groove 12g to secure fitment 12 to container 10. Additionally, the lower end portion 12c of fitment 12 has an internal tapered surface 12d shaped to snugly conform to the external tapered surface 14d of the container 10. Finally, fitment 12 is provided with an outwardly projecting shoulder or ledge 12e which is engaged by an internal shoulder 13b of a closure 13.

Closure 13 is of conventional inverted cup-shape configuration and is provided with a bottom recess 13a constructed to freely surround the fitment 12 and with an internally threaded portion 13c adapted to engage the threaded portion 102 of the container 10. The fitment engaging shoulder 13b of closure 13 is positioned intermediate the recess 13a and the threaded portion 130.

When, as shown in Fig. l, closure 13 is tightened on the container threads 10e, the shoulder 13b will engage the fitment shoulder 12:: and axially shift the fitment downwardly with respect to container 10, thus stressing tapered portion 12d of fitment 12 which surrounds the tapered surface 10d of the container 10, both by radial expansion and by contact with shoulder 10g. At the same time, the sealing rim 12b of fitment 12 will-be axially shifted into contact with the ball 11 to produce a seal Which prevents the loss of contents of the container 10. Obviously, rim 12b is tensionally extended when forced against the ball 11.

When the closure 13 is entirely or partially removed from container 10, as illustrated in Fig. 2, the fitment 12 shifts axially outwardly under the bias of the stressed tapered portion 12d and rim 12b. Hence an opening 15 is provided between the ball 11 and the sealing rim 12b of the fitment 12 and, when the container 10 is inverted and the ball 11 is rolled along the skin or other surface, the contents of container 10 will be transferred by ball 11 to the area which is contacted. In this convention the grooves 10b formed around the container opening 10a permit the free flow of fluid of the container 10 onto the surface of ball 11, irrespective of the amount of applicating pressure.

In the modification of this invention, illustrated in'Fig. 3, the fitment 14 is identical to the fitment 12 heretofore described with the exception that the lower portion of the fitment 14 is defined by a plurality of legs or tabs 14a which respectively engage the external tapered surface 10d of the container 10. The legs 14a are stressed by being compressed against shoulder 10g by the closure 13 when the latter is tightly attached to the container and by virtue of their resiliency function to shift the fitment 14 axially outwardly when the closure 13 is removed.

From the foregoing description, it will be apparent that the ball applicator construction of this invention provides an effective seal preventing leakage of the contents of the container when the closure is applied and yet permits unimpaired application of the fluid contents of the container by the applicator ball when the closure is removed.
