Y., a corporation of New York Application May `17, 1932, vserial No. 611,784 8 Claims. (Cl. 91-67.2)

The present invention pertains to closure caps Yand packages, and more particularly to an improved applicator cap.

Various products, such as glue, cement, nail I been chosen for purposes of illustration and def- 5 polishes and the like, require applicators for their proper use. It has not been found practical to supply such applicators independently of thepackage because the purchaser buys the package and fails to buy or obtain the applicator. Various attempts have been made to combine van applicator Witha closure cap or stopper. For `certain products, such as nail enamel, it has -been founddesirable to use a quill having a brush at one end for applying the enamel to the nails. The quill has very distinct advantages by' reason of the fact that it, isin'expensive, light in weight, and highly resistant lto the chemicals v `in the enamel. Attempts to attach the quill to `a closure cap have not been successful. The adhesives, in many cases, dry out and the quill becomes loose and, in other cases, the quillgsplits, rendering the brushuseless. It is' quite an an- 1 4noyance for the quill or applicator tofbreak be- .fore the'nail enamel has been used up. Numerous complaints `have been-,made because of this defect, but the other advantagesof the quill have caused manufacturers to continue` to sell Apackages provided with quillV applicators.

The present invention aims to provide an improved applicator' cap, particularly applicable to quill applicators, although certain of its features may be utilized `with other constructions, which .will eliminate or minimize the above objectionable features. g An object of the invention is to provide an improved inexpensive applicator cap.

Another object is to provide an` applicator cap with a quill applicator which is rugged in construction and fully capable of withstanding th usage to which it may be subjected. j

Another object of the invention is to prevent the splitting of the quill of the applicator during use thereof. 1 l

Another object of the invention-is to permit greater variations in the size of quills, without decreasing the elliciency and effectiveness of applikGators formed therefrom. A

Another object of theginvention is to provide a secure attachment between a closure cap and an applicator, particularly a quill type applicator. Y 1 I VOther and further objects ofthe invention Awill be obvious upon an understanding of` the illustrative embodiment to be described, or .will be indicated in the appended claims, and various Cil advantages not referred to herein will occur to one skilled inthe art upon employment of the invention in practice. Y

A preferred embodiment of the invention has scriptionand is shown in the accompanying drawing, forming a part of the specication, wherein Fig. l is a sectional view, with parts in elevation, of an applicator cap embodying the present invention; Y

Fig. 2 is an exploded view, partly in section, illustrating theparts before they are assembled;

Fig. 3 is an enlarged fragmentary, sectional view illustrating details of the quill attachment with the end of the quill extending into the well of thecap; A

Fig. 4 is an enlarged view, similar to Fig..3, of another construction embodying the invention;

Fig. 5 is an enlarged view, similar to Fig. 3,.of a slightly different construction; and 20 Fig. Y6 is a further modified embodiment illustrating the invention.

Referring again to the drawing, there is shown, in Fig. 1, a closure cap I having a cover portion 2 and a depending skirt 4, with screw threads'S on the interior thereof adapted to engage and cooperate with similar threads on a container to seal the cap thereon. A suitable gasket 6, made of cork, rubber, or other sealing material, may be utilized to secure a hermetic or liquid-tight seal u between the mouth of the container and the cover .portion of `a closure cap. Preferably, the closure cap Vis made from a moldable plastic material, such as phenolic condensation products,cellulose acetate molding compounds, and the like. At the central part of the cover cap, there is provided a depending extension I having a well, or aperture, 8 therein for the reception of the parts of the applicator.'

Ann applicator 9 is provided having a brush I0, of 40 `camels hair or the like, secured to one end thereof, the other ,end being tubular. Preferably, this applicator is made from a quill, or the like. A

-member II is provided having an enlarged end l2 adapted to t snugly into the well 8 of the Aclosure cap and a reduced end I4 adapted to fit into thefopen tubular end of the applicator member 9. The size of the reduced end I4 is suiii- 4ciently small to permit it to fit relatively loosely intheplarge size quills so that it will pass into 4the smaller sizes without splitting the quills. VThe additional space in the larger size quills may be `filled with cement I3, or other adhesive, to secure the member" I I to the quill. The end of the quill `preferably abuts against the shoulder I5,

intermediate the small and large ends of the member II.

The applicator S and member I i secured thereto are adaptedto t into the well 8 of the closure cap and to be secured therein by a suitable adhesive. If desired-the relative sizes of the enlarged end I 2 and the well 8 may be such that the parts are held in position by friction, but preferably a good cement is used to hold. the parts rigidly together.

While the shoulder l5 may be beyond the open end of the well 8, so that the applicator i) is held in position entirely by the member I I, preferably, as shown in Fig. 3, the shoulder I5 is within the well so that the open end of the tubular applicator member 9 extends into the well and-is held between the inner cylindrical surface of the well and the outer cylindrical surface of the reduced portion lli of the member I I. By supporting the quill on both sides, any tendency for Vthe quill to split at the Vopen end is eliminated; The friction between thewell and the quill, as well as the friction between the quill and the member I I, assists materially in holding the quill in position so that if the contents of the package attack the adhesives chemically, or if the adhesives dry out, the parts will tend to remain assembled.

As shown more particularly in Fig. 4, the inner surface of the open end yof the well may be flared outwardly, if desired, as shown at I 5, to facilitate the application of the parts. Y This is particularly advantageous where the quill is inserted into the well. In 'such instances, greater variations in size of the quill may be accommodated because the dared portion tends lto guide the quill and reduce its diameter slightly when it is forced into the well.

A slightly different construction is shown in Fig. 5, wherein the member `I YI may be cylindrical and of substantially the same diameter through- Good results may be obtained with this construction, although the assembling operation is not as convenient as with the constructions Vshown in Figs. l, 2, 3 and 4. It will be understood that the member II, in Fig. 5, should preferably fit loosely within the applicator quill to permit substantial variations in the size of the quills without splitting the quills during the assembling operation.

InV Fig. 6, a substantially cylindrical extension l1, depending from the cover portion of the cap, is provided, having the-.applicator quill Y9 telescoped thereabout. A sleeve Iii extends about the 'quill so that the quill is interposed between yshown herein, the closure cap may be formed by the usual molding operations and the gasket Ii, of cork or other material, may be inserted therein. The applicator 9 may be assembled with the reinforcing or holding peg I I and is then inserted into the well or aperture 8 of the. closure cap. Adhesive is applied to the-member Il, preferably beforeit is inserted'into the quill 9, and adhesive is likewise applied to the enlarged end I2 Vof Athe member II, or to the inner surface of the well 8 prior to the insertion of the member I I. The applicator is then an integral part of the cap, the cap forming a very convenient holder for the applicator. The assembled applicator cap is merely screwed on a suitable container to form a completed package. The parts of the applicator cap may be assembled by the cap manufacturer, or delivered to the packer in unassembled state, as desired.

It will be seen that the above invention provides a very effective sealing cap, with an applicator rigidly secured thereto, which is unlikely to become dislodged during the use thereof. The peg H may be rigidly secured within the well 8 of the closure cap without danger of dislodgment and may likewise be secured to the open tubular end of the applicator Si. The long extension Iii reinforces substantially the applicator quill and prevents breakage thereof. The member II may be made of wood, bakelite, or similar materials, and is inexpensive. The assembling operation is simplified rather than complicated by the additional element. The invention provides a very rigid construction which is fully capable of withstanding the rough usage to which it may be subjected.

As various changes may be made in the form, construction and arrangement of the parts herein without departing from the spirit and scope of the invention and without sacrificing any of its advantages, it is to be 'understood that all matter herein is to be interpreted as illustrative and not in a limiting sense.
