"Sponge order"

The invention relates to a sponge application head for placing on a bottle for a surface treatment agent, such as shoe paint, in particular shoe white. The term {J) 5 “bottle” is understood to mean any bottle-like container made of plastic, glass or metal.

There are two application systems with sponge applicators for ^ Shoe white and other color, namely containers with an applicator, e.g. a sponge, and a central opening on the one hand and applicators with a valve on the other. The former system is Only suitable for highly viscous products and cannot be used with thin paints, especially self-gloss emulsions will. The other system requires a relatively complex mechanism, which also only has discontinuous pumping movements allows.

The invention is based on the object of creating an application system with which self-gloss emulsions can also be used Shoe care and the like are to be applied, which is relatively inexpensive to manufacture and a continuous Product feed allowed. The solution for the sponge application head to be placed on a bottle is that the open-pored sponge is partially enclosed and compressed by an insert to be inserted into the bottle neck and Pils-like or spherical cap-like on the outside from the insert protrudes and that the insert below the uncompressed and radially protruding sponge edge a

An annular groove running approximately axially (in relation to the bottle opening) with an annular groove extending through the insert towards the interior of the bottle Has holes. A round cylindrical sponge is preferably provided and a cylindrical interior space for this assigned to the insert, which is intended to receive the sponge partially compressed when used.

The sponge application head according to the invention can of course be screwed airtight and product-tight for storage, so that unwanted product leakage is excluded even when the bottle is stored upside down. With unscrewed and the bottle held in the application position, on the other hand, is continuous via the holes provided in the application head To achieve product leakage. This is because the product is sent to the uncompressed via the ring groove - i.e. without filtration Edge area of the sponge body brought up. When the bottom of the ring groove has three receipts leading to the inside of the bottle Ments with preferably approximately the same mutual distance, results in a radial product flow to the three sides of the sponge corresponding to the holes and thus an optimal product distribution in the sponge. In this way a closed product film can be applied quickly.

An unexpected advantage of the sponge application head according to the invention also consists in the fact that the pils-shaped sponge upper part or the sponge cap is the one provided on the circumference The ring groove closes when it is pressed onto the object surface in the application position, so that unwanted, direct wetting the surface to be processed, e.g. leather, is avoided. For the same reason there is also an unwanted overdose practically impossible.

Accordingly, when the sponge application head is designed according to the invention, the advantages of known sponge applicators are achieved combined with valve applicators without taking over the above-mentioned Nao-hteile, in particular is A valve function is achieved without an additional valve element.

Further details are explained on the basis of the schematic representation of an exemplary embodiment. Show it:

The designated overall by 1 Schwammauf- invention \ _> support head comprises a sponge 2 which is partly enclosed by a (not shown) in a bottle neck to be plugged insert 3 and is compressed within the insert in the lower third in the ratio of about 4 s 1 . ^"S is used to compress preferably at the made facing the bottle interior bottom 4 of the insert provided, star-shaped on the inner Periferie clamping ring 5 of the insert 3 and the clamping ring are reached 5 3oll By dimensioning the inner space 9, that the sponge 2 is about a quarter or one third protrudes beyond the upper edge 6 of the insert 3 in the form of a mushroom or a spherical cap 7. It is important that the sponge 2 protrudes over the upper edge 6 of the insert 3, directed all around to the outside.

Below the uncompressed, radially protruding sponge edge 8 should be approximately axially in relation to the bottle opening extending and the inner space 9 of the insert 3 at a distance surrounding the annular groove 10 are provided. These Annular groove 10 should have through bores or holes 11 leading through the insert 3 to the inside of the bottle. Of the

The diameter of the holes 11 is adapted to the viscosity of the product to be applied. In the case of a thin self-

gloss emulsion with a viscosity of 100 cP and pigment size in the micrometer range, the bore diameter can be around 0.6 mm.

Obviously, in the case of the sponge application head according to the invention, the product is essentially not filtered through the sponge 2 but is fed directly to the spherical cap head 7 via the bores 11. The product passes through the axial borings ^ ^/ gene into the surrounding sponge annular groove 10 and from this in application attitude - toppled bottle - preferably to the bottom of the portion of sponge edge, which rests on the to bear yield surface and thereby the lowest position Arguably. Since the lower area of the annular groove 10 is covered by the sponge rim 8 because of the pressure on the surface to be treated, the bottle contents cannot directly wet the surface to be treated.

"Sponge application head"

Summary::

The sponge application head (1) is to be placed on a bottle and intended for applying shoe paint and the like. C '5 The application head should be designed so that it can be used without complex mechanical valves are also suitable for the continuous application of self-shine emulsions. According to the invention becomes a spherical cap protruding from an insert (3) Sponge (2) provided under the edge (8) of the insert (3) one via holes (11) with the inside of the plate connected annular groove (10) has (Pig. 1).
