SP~NGE APPLIC~TOR HEAD -- This invention is di~ected to a sponge ~pplica~or he~d~
More particularly, this invention is direc~ed ~o a sponge app.~ic~a:-tor head to be attache~ to the top of a bottle ~or ~reatment of ~J

Z7Si It is an object of ~he invention to provide a novel sponge applicator system.

; It is also an object of the invention to provide an applicator system for applying self-polishing emulsions for shoe care.

It is a further object of the invention to provide an applicator system that is relatively simple to produce and that pern~its continuous supply of product.

.
It is a yet further object of the invention to provide a sponge applicator head attachable to a bottle for dispensing a liquid for treatment of a surface, which head comprises a casing to be inserted into the neck of the bottle, said casing having top and bottom surfaces, and an open-pore sponge partially enclosed and compressed by the casing to form a projecting, substantially mushroom-shaped or semi-spherical aap of uncompressed sponge just above the top surface of the casing, the top surface of the casing having beneath the cap of uncompressed sponge a substantially axially extending circular groove with from 3 to 5 openings passing axially through the casing to the bottom surface thereof, said openings being spaced approximately equidistantly from each other within said circular groove, and the surface of the uncornpressed sponge adjacent to the surface of the casing projecting radially beyond said circular groove, the circular groove and the surface of the uncompressed sponge being positioned so that (1) when said bottle is inverted, said liquid passes through said openings to the surface of the uncompressed sponge adjacent to the top surface of the casing and (2) when the head is pressed on a surface, the surface of the uncompressed sponge adjacent to the top surface of the casing presses against and closes said circular groove to stop the flow of said liquid.

, These and other objects of the invention will become more apparent in the discusFion below.

Fig. 1 represènts a partial cross~sect.ional view ~.f an embodiment of the invention; and Fig. 2 represents a sectional view through line II~II of the embodiment of the invention shown in Fig. 1, with the sponge re ved.

Applicants have surpxisingly de~eloped a relat:ively simple sponge applicator system which is suitable for continuously applying self-polishing emulsionsO According to thelr inventionp a bottle has a sponge appl.icator head whiçh comprises a casing to be inserted into the neck of the bo-ttle and an open-pore sponge partially enclosed and compressed by ~he casing ~o form a projecting, substantially mushroom-shaped or sem~. spherical cap .of uncompressed sponge just above the outer surface of the casingO
The outer surface of the casing has a substantially axially ex-~ending circular groove with one or more, preferably from 3 to 5, openings or perforations.passing axially thxough the casing to its inner surface. This groove is positionea below the radially projecting edge of the cap of uncompressed sponge~

The sponge itself, in its wholly uncompressed state, such as it would be pr:ior to insertion in the casing, is prefexably cylindrical. Sim:ilarly, the inter.ior of the casing is substan-tially cylindrica:L, with the exception of a member~ such as a ring clamp, at the.bottom surface of the casing which has an 1;~2;~7S

opening slgnificantl~- smaller.in dîa~le~er thall the in~er:ior of the casingc The portion of the sponge wi~hirl the cas;i.rl~ ~s a whole is compressed from a~out 20 ~o 70%, ~hal- is, the cr~ss~se~-~tional area of the compressed sponge co~p~lse~ abo~.t 30 ~o 8 n~
o~ the cross-section~l aréa of thè uncompressed sp~n~eF while ~:h.~
sponge }5 compressed in the rins clamp from abou~c 70 ~o ~S%y that is, the cross-sec'ciGnal area o the co~pressed~sponge ~ompr:ises ~rom about 5 to 3G% of the cross~sectj.onal area of ~he uncompres~
sed spongeO

The applicator head of~-the invention carl ~e attached to an~
suitable bottleO The term "bottle" as used he.rein i~cludes any single~necked container of rigid or suh~tan~ially r.igid materi7.1 such as glass r ~.etal, or plas~ic.

It is wlthin the ~cope of the inven~i.on tha~ the applicator head may have a substantially rigid covering or cap that can be.
- snapped or screwed onto the applicator head, or even the bottle~
for air-tight and product-ti~ht storage, especially so that unde~
sirable product leakage is prevented. if ~he ~ottle is stored on its head.. The covexing or cap should be configured to cau~e the mushroom-shaped or spherical cap.to press against and close off the circular groove in the outer surface of the casing~

In another embodi.ment of the inven~ion, the latcral sur~ace of the casiny is designed so that in one po.sition in the neck of a bottle the product can pass through -the openings and through the circular groove to the uncompressed sponge cap. ~owever~ when the applicator head is pushed or screwed fur-ther into the bottle neck, the sides o~ the casing act to close the circular groove and thus preven~ the flow o~ product.

~L2~'75 ConLinuous product flo~-through thè operlincJs lo~a~ed :in the applicator head 1~ possi~le when the bott~e i~ unsc:rewed and he:ld in application posi~ion~ This i~ the result-. of channelin~ th~
product through t'ne circular ~roove ~- thus witllout fil-tratior to the uncompressed edge zone Q~ the sponge bod~0 When ~e bott~o~
of the circula.r groove has three openinss leading to the bott:le interior, prefera~ly at mu~uall~ equid;stant posi-~3.0nsg a radial flow of product to the three sides of ~he sponge corresponding t~
the openings is obtained, and therefore there is an op~imal pr~
duct distribution in the sponge. ~ coverîng produc~ film can ~e applied quickly b~- this method~

, An unexpected additional ad~an~age of the sponge appli.cator head accurdin~ the inventlon is the closin~ of the peripherally provided circular ~roove by the mu~hroom-shaped or spherical upper:
sponge part in application position, as it is pressed on the .sur-face of theobjectt which prevents the involuntary direct wetting OI the surface to be treat~d, for exampleS lea~her. Unwanted excessive product application is prac-~ically impossible for the same reason.

- Thus, when the sponge applicator head is constructed accord-ing to the invention, the advantages of known sponge applicator heads are combined with the advantages of known valve applicators without introduction o~ the disadvan-tages mentioned above~ More succinctly, a valve action is ohtained withou~ an added valve element.

Applicants' invention can perhaps be better appreciated by making reference to the drawinys. The sponge applicator head de-.

s signated as l in i-ts entirety contai.ns a spon~Je 2, which i5 par tially enclosed by a casing 3 tha~ is to be insertec1 into a bo~:~le neck ~no~ shown). The lower ~hird of ~he sponye 2 is compress~
at a ratio of approximately'4:1, in terms of cross~sectional are~ r-within the casing. A rin~ clamp 5, which can he star~shap,ed at, its inner periphery and is located at the bottom 4 o~' the casi~g facing the ~ottle interior is preferably used fox t.he compre~.si~r The interior space 9 of ~asing 3 and ring clamp 5 have the proper dimensions to allow approximately one-quarter or one~third of sponge 2 to extend in the form of a mushrovm or a semi-sphericaL
ball 7 over the upper e'dge 6 of casing 3O It is important that sponge 2 project radially outward over the upper edge 6 of casillg
3 to form a closed collar.

Below the uncompressed, radially proiecting sponge edge 8 F
a circular groove 10 ringing the interior space 9 of casing 3 ori~
ented approximately axially with regard to the bottle opening is provided, there being a wall 12, between circular groove 10 and interior space 9. This circular groove 10 shall have through prefo~ations or openings 11 leading through casing 3 into the bottle interior. The dia~eter of the openings 11 is adjusted according to the viscosity of the product to be applied. For exam-ple, the diameter of éach opening may ~e approximately 0.6 mm for a thin liquid such as a self-polishing emulsion with a viscosity o 100 cP and a pigment s,ize of the ~icrometer range.

Obviously, the product is essentially not filtered over the length of sponge 2 in the sponge applicator head according to the invention but is channeled directly through openings ll to semi-spherical cap head 7. When the applicator is in an application , : ...... . , .... , .. ~ , . . ~

ably to -the underside of the area of sponqe edge 8~ During ~uch use sponge edge 8 touches the surface to ~e trea~ed and thus occupies the lowest position. ~ direct wetting of -the surface to be treated with the bottle contents, that is, ~he product, cannot occur since the lower area of circular yroove 10 is covered hy sponge edge 8 due to pressing against ~he surface to be treate~

Various modifications of the process and products of the invention may be made without departing from the spirit or scope thereof and it should be understood that t~he invention is intended to be limited o~l.y as defined in the appended claims.
