Problems solved by technology

However, this setup is labor-intensive and not without dangers
[0007] One of the main disadvantages of known sponges is the uniform porous or pore structure along the entire volume of the sponge

Embodiment Construction

[0063] figure 1 A mold for producing a sponge according to the method of the invention is shown schematically. The mold comprises two mold halves 11 and 12 defining a cavity 15 between them. Foamed plastic material, in particular soft polyurethane foam, can be introduced via a delivery channel 16 into the mold cavity 15 and foamed therein, as indicated by the arrow M. FIG. The size and shape of the mold cavity 15 correspond substantially to the final shape or configuration of the sponge. After opening the mold, a reinforced shell 13 with an internal uniform closed-cell structure and continuous closure is obtained, which is relatively stable and can be formed on the outside of the sponge body 10 by selectively adjusting the method parameters in the foaming process, as shown in the figure shown in 2. The shell 13 can be partly excised in order to obtain the spongy body 10 shown in FIG. The remaining solid housing 13 can be used as a stable handle part for the user or for mou...

Abstract

The invention relates to a method for producing a cleaning or application sponge which is characterized by foaming a sponge body in a molding tool to the substantially final shape of the sponge. The outer surface of the sponge body has in at least some areas a solidified skin that can be at least partially removed in a subsequent process step. Moreover, the sponge body may also have a closed-cell structure that is partially revealed in a subsequent process step.

Description

technical field [0001] The invention relates to a method for producing a cleaning or application sponge and a cleaning or application device equipped with a corresponding sponge or sponge body. Background technique [0002] In order to produce cleaning and coating sponges, such as are now used in particular for housework, it is known to first produce a relatively large block of polyurethane foam with a cuboid or cubic shape. A sponge is then produced from this block of foam by cutting and / or impacting. If handle grooves are additionally produced in the sponge or its edges are chamfered, the sponge has to be subjected to a subsequent milling process. This known production method is disadvantageous in many respects. [0003] On the one hand, the method is complex and expensive due to the multiple method steps to be carried out in succession. Furthermore, the foam blocks are usually not produced by the sponge manufacturer themselves, but purchased from third parties, so that...
