a w. Asa-am CH A-fr'cavlavs United States Patent 3,259,935 CLOSURE RETAINER Ira H. Miller, Lambertville, Mich., assiguor to Owens- Illinois, Inc., a corporation of Ohio Filed Mar. 16, 1962, Ser. No. 180,092 13 Claims. (Cl. 15571) This invention relates generally to a closure retainer and more specifically to a retainer for rotatably securing an elliptical closure to an article having an elliptical openmg.

It is well known to provide screw closures for articles having circular openings with the attendant ease of re-. moval and replacement of the same. It is also desirable to provide an article with a non-circular opening with a rotatable closure. To my knowledge, the prior art does not provide such a closure.

With the advent of liquid dispensers and applicators, utilizing a ball as the applicator, there has arisen a need to apply a larger amount of liquid that is possible with a ball. It has been suggested that a roller and more specifically a-n ellipsoidal roller be used as the applicator. Because of the many times that such applicators are used before the contents are exhausted, it is desirable to provide an efiective closure but one which is easily removable.

It is therefore an object of this invention to provide means for rotatably securing a closure to an article.

-It is a further object of my invention to provide means for rotatably securing a closure to a non-circular opening.

Another object of my invention is to provide means for rotatably securing an elliptical closure to an elliptical opening.

A further object of my invention is to provide a screw closure for a liquid dispenser and applicator assembly having an elliptical finish.

These and other objects of this invention will be apparent from a reading of the following detailed description taken in conjunction with the drawing wherein:

FIGURE 1 is a prospective view partially broken away of a liquid dispenser and applicator assembly embodying this invention;

FIGURE 2 is a bottom plan view of the closure cap of FIGURE 1;

FIGURE 3 is a bottom plan view of the unattached retainer ring of this invention;

FIGURE 4 is a perspective view of the assembled closure cap and retainer ring according to this invention; and

FIGURE 5 is a bottom plan view of the closure cap and retainer ring of FIGURE 4.

In brief, this invention contemplates a flexible and deformable ring of thermoplastic material which encircles the lower end of a closure for the article to be sealed. Means are provided on the interior of the closure for rotatably securing the ring to the article. The ring is provided with means for holding the closure in closing relationship to the article.

This invention will be illustrated and described with reference to its application to a liquid dispenser and applicator assembly. It should therefore be understood that this invention is also applicable to the closing or sealing of other articles which require a rotatable closure.

Referring now to the drawing wherein one embodiment of this invention is ilustrated, reference numeral denotes a container for deodorants, lotions, perfumes or similar cosmetic compositions that are commonly applied directly to the body, or for any liquid that requires application to another surface as a film, such as glue, shoe polish, etc.

Container 10 may be formed of glass, thenmoplastics, or other similar materials. In the particular example of Patented July 12, 1966 the invention herein described, the container 10 has an elliptical wall 11 which at its free or upper end 12 defines a mouth opening of elliptical configuration. Exteriorly of'this wall 11 and adjacent its free end is an annular upwardly facing shoulder or abutment 13. Screw threads 14 which may be continuous or discontinuous are provided on the exterior of the neck 11 below the shoulder 13. An applicator retaining fitment 15 is provided for mounting on the open end of container 10, as, for example, by insertion into the mouth opening of the container 10.

This fitment 15 which may be formed of polyethylene or other similar elastomeric materials is elliptical in configuration. The specific details of the construction of this fitment are shown and described in my copending application Serial No. 98,360, filed March 27, 4961, and entitled Liquid Dispenser and Applicator, and owned by the common assignee herewith.

The upper portion of fitment 15 is formed by an upstanding peripheral wall 16 which defines an applicator accommodating socket of elliptical configuration. This socket is so constructed so as to readily accommodate an ellipsoidal roller or applicator 17. The major axes of the elliptical shaped parts of the fitment 15 are parallel to each other, thereby affording a compact liquid dispensing and applicator assembly. The roller 17 may be formed of glass, polystyrene, or other similar rigid or semi-rigid materials. The roller 17 is freely rotatable in the socket of the fitment 15 in order that the same may function readily as a liquid applicator and dispenser.

A closure cap 20 which may be formed of polyethylene or other elastomeric materials having similar characterist-ics comprises an elliptical top panel portion 21 and an elliptical depending attaching skirt 22. An annular, radially and outwardly extending flange 23 is provided at or near the lower end of the skirt 22. The function of flange 23 will explained hereinafter.

Interiorly of the closure cap 26 are provided two de pending flexible ribs 24, whose function and design are more specifically described in .the above identified copending application. The ribs 24 are resiliently deformed when the closure cap 20 is secured to the container 10 by means to be discussed, thus forcing and maintaining the roller 17 in sealing contact with the fitment 16 and thereby preventing leakage of the contents of the container when the closure cap 20 is secured thereto. Other means for sealing the package may be resorted to without departing'from the spirit and scope of this application.

The closure cap 20 is secured to the container 10 by rotatable, flexible and deformable ring 25. The ring 25 is formed of flexible thermoplastic materials such as low-density polyethylene. Other thermoplastic materials which are resiliently deformable may be used. The ring 25 in its unattached state is circular in configuration as is shown in FIGURE 3. After it has been pressed over the closure cap 20 it assumes a configuration corresponding to the configuration of the lower portion of the skirt 22 of the closure cap.

Interiorly of the ring 25 are threads 26 which mate with the threads 14 on the container 10 to secure the ring and closure to the container. The upper portion of the ring is provided with a radially and inwardly extending rib or shoulder 27 which mates with the rib 23* on the closure cap 20 to prevent dislodgement of the closure cap and also to hold the same in sealing position to the applicator assembly.

The exterior of the ring 25 is provided with a plurality of parallel grooves 28 which extend from the upper extremity of the ring to substantially the lower extremity of the ring. The grooves 28 extend in a direction parallel to'the axis of rotation of the ring 25 and improve the flexibility of the ring.

In operation the circular ring 25 is telescoped over the non-circular or elliptical closure cap 2t) and pushed downwardly until shoulder 27 on the ring 25 comes to rest against the rib 23 on the closure cap 20. In this position the ring 25 is freely rotatable with respect to the stationary cap 20. t

The closure20 and ring 25 are then telescoped over the threaded end of container or any other article which is to be closed by this assembly. The threads 26 on the ring 25 are brought into registry with the container threads 14. Thereafter the ring 25 is rotated while the cap 20 does not rotate. Their rotation pulls the ring and cap downwardly with respect to the fitment 16 and container 10 until the rib 23 comes to rest against the shoulder 13 on the container 10. This flexes the ribs 24 thereby forcing roller 17 into sealing engagement with the fitment 16.

If this closure assembly is used with articles other than the liquid dispensers and applicator assembly shown in the drawing, means other than ribs 24 will be used to seal the. article. For example, a gasket may be provided in the closure which upon rotation of the ring and subsequent downward movement of the closure and ring will come into sealing contact with the open end of the article.

Heretofore,it was not thought possible to utilize a screw closure for an article. such as a container which was provided with a non-circular opening. This invention makes it possible to seal such an opening with a closure cap which corresponds to the configuration of the opening, but one which is provided with a screw-threaded flexible and rotatable ring which forces and maintains the closure in sealing contact with the article.

It should, therefore, be understood that various details of construction may be modified without departing from the spirit and scope of this invention which is to be limited only by the following claims.
