Packaging - Glass Cleaner - The idea here is the union between the glass cleaner (while liquid) and the cloth or some absorbing surface needed during the wipe. Thus, this package consists of two elements:the container of the glass cleaner liquid - who suffers from an opening to the liquid outlet and two holes to engage the second element, termed the plastic holder for the sponge. Fitting these two parts, the liquid passes into the sponge, moistened it. Now it just passes through the area to be cleaned.
