Abstract

1. Sponge applicator head (1) for placing on a bottle for a surface treatment medium, such as shoe dye, particularly shoe whitener, wherein the open-pored sponge (2) is partially enclosed as well as compressed by an insert (3) to be plugged into the bottle neck and protrudes from the insert (3) on the outside in the shape of a mushroom or calotte, characterised thereby, that the insert (3) - underneath the uncompressed as well as radially projecting sponge rim (8) - possesses an about axially extending annular groove (10) with holes (11) passing through the insert (3) to the interior of the bottle.

Description

DK 153664 B

The invention relates to a sponge application head of the type specified in the preamble of claim 1. By the term "bottle" is meant here any arbitrary ash-like container of plastic, glass or metal.

There are two application systems with sponges for applying shoe-white and other color, namely partly containers with an applicator, e.g. a sponge, and a central opening and partly applicators with valve. The first system is only suitable for very viscous products and cannot be used for thin colors, especially self-gloss emulsions. The second system presupposes a relatively expensive mechanics, which even allows only discontinuous pumping movements.

From Fr. U.S. Pat. No. 1,229,213 discloses a container for liquid bucket care agents with a stopper of porous material which serves as an applicator. This device is designed such that a neck ring is connected to the central opening of the container bottom, which is designed as a consideration for securing the plug of the plug part serving in the support body behind the free end of the neck ring.

Furthermore, DE-B-1,255,543 discloses an application device in connection with a liquid container, in which a closing body in the form of a disc with an adjoining lower part with a smaller diameter and a cavity 25 is inserted in an opening in the container. a control head with pin is inserted in the closing body.

Here it is indicated that the closing body consists of an elastic stretchable material, that the application head with a rigid pin sits on the bottom of the cavity, and that the closing body has a number of bores which on one side usually end at the side wall of the opening, but 30 the applicator head and the corresponding stretch of the closure body come into contact with the interior of the container and allow the liquid to flow out.

In relation to this prior art, the object of the present invention is to improve the known application systems in such a way that with the application head one can apply own gloss emulsions for the care of shoes and similar means, and that the application head is relatively cheap to manufacture and mu - 2

lies a continuous supply of product. In particular, a valve effect must be obtained in such a way that an overdose of the applicator is practically ruled out.

This object is achieved in that the initially applied fungal application head according to the invention is characterized by what is stated in the characterizing part of claim 1. Hereby it is achieved that the liquid product can flow out via the holes in the ring groove, without the product on the way to the surface to be treated also having to pass through the application sponge. When the product flow is to be interrupted - e.g. in case of overdose - close the outflow opening by pressing the edge of the mushroom-shaped application sponge against the openings of the groove. It is sufficient to press the sponge against the treated surface, e.g. school law. Upon relieving the pressure, additional product flows out onto the outer surface of the applicator sponge. In addition to preventing the filtration effect, it is also advantageous that the application head according to the invention easily enables adaptation to other product viscosities. This is done by appropriately dimensioning the holes leading to the inner holes of the 2Q bottle.

Although it is possible to use a sponge which has been given the mushroom shape during manufacture, a round cylindrical sponge, preferably arranged in the cup-shaped space of the insert 25, which is to be used in use, is preferably used in accordance with the characterizing part of claim 2. record the fungus partially compressed with the mushroom-shaped top protruding from the inner space. This makes the sponge application head cheap to manufacture. The fungus can e.g. maintained by gluing. In order to hold the sponge against axial displacement in the insert in an even more economical way, it is indicated that there is an inner star-shaped clamping ring in the bottom of the insert. In addition to holding the sponge against axial displacement, this star-shaped clamping ring squeezes the sponge together so much that in practice no product outflow occurs through the sponge.

In order in the simplest and cheapest way to give the fungus projecting from the outside of the insert the desired mushroom or cap shape, it is instructed in accordance with the method 35

The drawing part of claim 4 further stated that the sponge in the area of the clamping ring is compressed approximately in the ratio 4: 1, which helps to avoid producing a complicated shaped sponge.

When the bottom of the ring groove has three leading bores towards the inner of the bottle with preferably an equal distance between them, a radial product influx is obtained to the three sponge sides corresponding to the bores, and thus an optimal product distribution on the sponge. In this way, a closed product membrane can be quickly applied.

Accordingly, the advantages of known sponge applicators are combined with vent in applicator means in the design of the sponge applicator head according to the invention, without taking over the disadvantages mentioned in the introduction, in particular obtaining a vent in 1 function in on 15 without additional valve element.

The sponge application head according to the invention can, of course, be screwed airtight and product tight for storage, so that an unintentional product outflow is also excluded when the bottle is stored upside down.

On the basis of the schematic representation of an exemplary embodiment, further details are explained below. In the drawing, fig. 1 is a side view of a sponge application head and partly in section, and FIG. 2 the same along the section II-II in fig. 1.

The sponge application head according to the invention, designated in its entirety by the reference numeral 1, contains a sponge 2 which is partially enclosed by an insert 3 to be placed in a bottleneck (not shown). When the sponge is pressed into the insert, the lower third is compressed in the ratio approx. 4: 1.

For compression, a star-shaped clamping ring 5 formed on its inner periphery is preferably used, which is formed integrally with the bottom 4 of the insert facing the inner part of the bottle.
