1 Claim. (Cl. 15-140.4)

This invention relates to a novel container for a liquid having volatile constituents, such as nail polish, paint, rubber cement, adhesives, corn remover, ink eradicator and the like and has for a primary object to provide a novel storage container for a reserve supply of the volatile ingredient or ingredients and which may be utilized for replenishing such ingredients which have evaporated from the container for restoring the contents of the container to its original condition and for thus rendering the container contents usable.

Still another object of the invention is to provide a novel container structure whereby the principal cause of loss of volatile ingredients of a liquid through evaporation is eliminated.

Still another object of the invention is to provide a container having a novel applicator supporting handleclosure wherein a portion of the handle-closure'is detachable and constitutes the storage chamber of the reserve supply of a diluting liquid.

Still another object of the invention is to provide the closure-handle structure wherein the handle portion forming the reserve supply is capable of being deformed for ex- .truding the contents therefrom by a compressing action,

which will resume its normal shape when a compressing force is released therefrom and which is so shaped that said handle portion may be gripped tightly without yielding when employed as a supporting handle.

A further object of the invention is to provide a container having a novel construction whereby substantially all of the contents in the container may be utilized and removed therefrom with the closure-handle supported applicator.

Various other objects and advantages of the invention will hereinafter become more fully apparent from the following description of the drawing, illustrating presently preferred embodiments thereof, and wherein;

Figure 1 is a side elevational view of the container completely assembled;

Figure 2 is an enlarged longitudinal sectional view thereof taken substantially along a plane as indicated by the line 22 of Figure 1;

Figure 3 is a cross sectional view of the hollow handle member taken substantially along a plane as indicated by the line 33 of Figure 2;

Figure 4 is an enlarged fragmentary central sectional view of a modified form of the handle member;

Figure 5 is an enlarged fragmentary longitudinal sectional view illustrating another modification of the handle member, and

Figure 6 is a view similar to Figure 4 illustrating another modification of the handle member.

Referring more specifically to the drawing, and first with reference to Figures 1 to 3, the reference numeral 8 designates a container which may be formed of any suitable material such as glass and which is provided with a restricted externally threaded neck 9. The container 8 may be of any desired external shape and size and may 2,736,050 Patented Feb. 28, 1956,

be assumed to constitute a container for nail polish, not shown.

The container neck 9 is normally closed by a cap 10 which may be formed of plastic, hard rubber or any other suitable material. One end of the cap 10 is provided with an outwardly opening internally threaded recess 11 which threadedly receives the externally threaded neck 9 for closing the bore 12 of said neck. Said cap 10 is provided with a boss extending into the inner closed end of the recess 11 and which boss 13 fits into the outer end of the neck bore 12 when the cap 10 is in a fully applied position, as illustrated in Figure 2. The opposite end of the cap 10 is provided with an internally threaded recess or well 14 which opens outwardly of the upper end thereof and in the bottom portion of which is seated a sealing disk 15 of a suitable compressible material.

An elongated plume-like hollow handle member 16 is provided with a restricted externally threaded neck 17 at one end thereof which threadedly engages in the well 14 for detachably connecting said handle to the upper end of the cap 10, and the extremity of which neck 17 bears against the sealing disk 15. A bore 18 extends longitudinally through the neck 17 and has one end opening outwardly of the terminal thereof and its opposite end opening into a storage chamber 19 defined by the hollow interior of said handle 16. The handle 16 is preferably formed of plastic and has a relative thin wall 20 surrounding the chamber 19. Said handle 16 is preferably of oval shaped cross section as illustrated in Figure 3 and the wall 20 thereof is capable of being deformed or collapsed inwardly to reduce the size of the chamber 19 for ejecting the contents thereof outwardly through the dispensing neck bore 18. Said wall 20 resumes its normal shape as illustrated in Figures 1, 2 and 3 when a compressing force is released therefrom. It will be understood that any other suitable material may be employed in forming the handle 16 which is resilient or yieldable and capable of being deformed by a compressing force and of resuming its normal shape when the force is released therefrom. Due to the oval cross sectional shape of the handle 16, the opposite longer sides thereof may be more readily compressed or displaced toward one another for restricting the chamber 19 than the more remote rounded longitudinal edges, for a purpose that will hereinafter be described. The handle 16 is preferably tapered toward each end thereof and has an upper closed end 21 of solid construction which is tapered to substantially a rounded point. A small sealing element or plug 29 is preferably disposed in the outer end of the bore 18 after the chamber 19 has been initially filled through said bore with a liquid for diluting the contents of the container 8 after volatile ingredients of the contents of the container 8 have evaporated and for replacing said evaporated ingredients. However, it will be readily understood that the storage chamber 19 may contain any suitable liquid not necessarily for the purpose of diluting the contents of the container 8.

An applicator, designated generally 22, includes an elongated brush head 23 composed of a mass of bristles, one end of which mass is anchored in a conventional manner to one end of an elongated handle or stem 24. The opposite end of the handle or stem is embedded in the intermediate portion of the cap or closure 10 and extends from the boss 13 thereof centrally through and outwardly of the recess 11. As seen in Figure 2, the bottom of the container 8 is provided with a concave or dished inner side 25, the lowermost central portion of which is disposed centrally beneath the neck 9. The applicator 22 is of such a length that When the cap 10 is in a fully applied position on the container neck 9,

. the free end of the brush head 23 will be disposed directly over and substantially contacting the central portion of the concave bottom surface 25. A sleeve 26 is suitably secured in the neck bore 12 below the boss 13 and has a restricted lower end 27 terminating in a restricted opening or throat 28 which is only slightly larger in diameter than the stem 24. It will thus be seen that the applicator head 23 will be compressed or drawn together as it is withdrawn through the throat 28 for extracting any excess liquid therefrom and which liquid will drain back into the container 8, leaving only the proper amount of liquid on the applicator head 23 to be applied thereby to a surface without dripping therefrom and to additionally prevent liquid from the applicator head dripping onto the neck 9. The throat 28 additionally eliminates the need of wiping excess liquid from the applicator head on the rim of the neck 9 and thus maintains the neck in a clean condition so that it may fully seat in and be closed by the cap to prevent or minimize evaporation of the volatile ingredients of the contents of the container 8. The concavely rounded inner side of the restricted portion 27 will compress the applicator head 23 as it is applied to the container 3 to allow it to pass readily through the throat 28. When the contents of the container 8 is substantially exhausted the remainder of the contents will readily drain into the central portion of the dished bottom 25 with which the brush head 23 substantially contacts so that substantially all of the contents of the container 8 may be withdrawn therefrom by the applicator head 23.

The chamber 19 of the handle 16 is filled, for example, with a liquid, not shown, to dilute the contents, not shown, of the container 8 after said contents have been rendered unusable by evaporation of volatile ingredients thereof to cause the container contents to resume a con sistency of a character enabling the contents to be used for its intended purpose. After the chamber 19 has been filled through the bore 13 with the diluent or the like, the outer end of said bore is preferably sealed with a plug 29 and the end portion 17 is then threaded into the well 14. As the contents of the container 3 is normally used by the purchaser in small amounts at a time and as air reaches the contents while the closure- handle 10, 16 is removed with the applicator 22 for applying the container contents to a surface, ordinarily before the contents is used up, said contents becomes too thick to be efficiently used. When this occurs, the handle 16 is unscrewed from the cap 10 and a pin or similar pointed instrument may be used for disengaging the plug 29 and forcing it through the bore 18 into the storage chamber 19. The dispensing neck 17 may then be inserted into or positioned over the neck bore 12 and by gripping the wide portions of the wall 20 between the thumb and finger, said wide wall portions can be displaced toward one another for partially collapsing the handle 16 for e ecting a part of the contents of the chamber 19 through the bore 18 into the container 8 to dilute the contentts of the container by thus replacing the evaporated ingredientsthereof. When pressure is released from the wide opposite portions of the wall 20, the handle 16 will resume its normal shape as illustrated in Figures 1, 2 and 3. After a sufiicient amount of the contents of the storage chamber 19 has thus been ejected therefrom into the container 8, the neck 17 is screwed back into the well 14 and its outer end seats against the sealing disk 15 for sealing the outer end of the bore 18. The reservo1r handle 16 may be gripped relatively tight between the thumb and fingers by exerting pressure on the rounded remotely disposed edge portions thereof without causing any collapsing of the handle so that the handle can thus be gripped together with the closure 10 while the applicator 22 is being utilized.

Figure 4 illustrates a slightly modified form of the discharge end of the handle, designated 16a, and wherein the stem portion 17a is provided with a relatively large bore 18a through which the storage chamber 19a may be filled. Thereafter, an elongated plug is inserted into the bore 18:: and is suitably sealed therein to provide a liquid tight seal. The plug 30 extends from endto-end of the bore 18a and has a flanged outer end 31 which bears against the outer end of the stem 17a. The plug 3% has a dispensing bore 32 extending from end-toend therethrough which opens into the chamber 19:: and outwardly through the flanged end 31. Said bore 32 is preferably closed and sealed adjacent its outer end by a plug 2% corresponding to the plug 29 and which functions in the same manner and for the same purpose. The outer end of the flanged head 31 seats against a sealing gasket 15a of the closure 10a for sealing the outer end of the bore 32 after the plug 2% has been removed. It will be readily apparent that the storage chamber 1% may be much more readily filled through the bore 18a than the storage chamber 19.

Figure 5 illustrates another modification of the handle to facilitate the initial filling thereof and wherein the closed upper end 21b may be formed separately from the remainder of the handle 16b so that the storage chamher 1% may be filled initially from the upper end thereof through the opening 33 after which the plug portion 34 is secured in said opening 33 to provide a liquid tight seal and to permanently secure the handle end 2117 in place.- Said handle end 21b conforms externally to the contour of the handle end 21 and provides a smooth extension of the external surface of said handle 16b.

Figure 6 illustrates another modification of the handle and wherein said handle 160 is provided with a large opening 35 at its lower end through which the storage chamber 19c can be readily filled. The opening 35 is then closed by a plug portion 36 of a dispensing neck 37 which is secured in a liquid tight engagement in the opening 35. The stem 37 has an annularly enlarged portion 38 adjacent the plug 36, one end of which bears against the lower end of the handle 16c, and a threaded portion 39 extends from the opposite end of the enlargement 38 and threadedly engages the well of the closure 100. A dispensing bore 40 extends from end-to-end through the stem 37 and communicates with the chamber 190. Said bore is preferably tapered from its inner end to adjacent its outer end and is sealed adjacent its restricted outer end by a sealing plug 290. After the seal 290 has been broken, the flared discharge end 41 of the bore 40 is sealed by the sealing disk when the stern portion 39 is fully applied to the well 140.

Various other modifications and changes are contemplated and may obviously be resorted to, without departing from the spirit or scope of the invention as hereinafter defined by the appended claim.

I claim as my invention:

A container structure of the character described corn prising a liquid container having an externally threaded neck, a throat member mounted in said neck and provided at its lower end with a restricted throat opening, a cap having a threaded socket in one end thereof threadedly receiving and closing said threaded neck, an applicator including a stem having one end anchored in said cap and extending therefrom outwardly through the neck receiving socket and supported by the cap within said container, said applicator including a brush head depending from the opposite end of said stem and supported thereby within the container, said throat opening being sized to compress the brush head when the applicator is withdrawn from the container whereby excess liquid is squeezed from the brush head, an elongated handle detachably connected to and projecting from the opposite end of said cap and provided with a hollow interior constituting a liquid storage chamber for a liquid to be supplied to said container, said cap having an upwardly opening threaded well in its upper end, a sealing means in the bottom of said well, and said handle having a threaded disnharge stem at its lower end threadedly engaging said well and having a bore extending longitudinally therethrough through which the contents of said chamber is adapted to be discharged, the outer end of said bore being closed by said sealing means when said handle is engaged with the cap, and said handle having a relatively thin yieldable wall surrounding the storage chamber thereof capable of being partially collapsed by a compressing pressure thereon for restricting the storage chamber to eject the contents thereof through the dispenser bore when the handle is disconnected from the closure and which wall will return to its normal shape when the compressing force is released therefrom to provide a relatively stiff, non-limber handle.
