Abstract
The process for manufacturing a multi-element sponge consists of mixing together a polymer and a reagent to form a mixture to be expanded to produce a spongy mass, casting the mixture in a mould, depositing an insert onto said mixture and allowing the mixture to expand while maintaining the insert pressed against it, so that on termination of expansion the insert is directly connected to the spongy mass.
Claims28
A process for manufacturing a multi-element sponge consisting of mixing together a polymer and a reagent to form a mixture to be expanded to produce a spongy mass, casting the mixture in a mould, depositing an insert unto said mixture and allowing the mixture to expand while maintaining the insert in contact with it at least for a part of the expansion, so that on termination of expansion the insert is directly connected to the spongy mass.
A process for manufacturing a multi-element cleaning implement consisting of mixing together a polymer and a reagent to form a mixture to be cured, casting the mixture in a mould, depositing an insert unto said mixture and allowing the mixture to cure while maintaining the insert in contact with it at least for a part of the curing, so that on termination of curing the insert is directly connected to the cured mixture.
A cleaning implement comprising a cleaning mesh to which a support element is connected, said cleaning implement comprising a disc connected to a free edge of said support element and arranged to protect the user's hand.
A cleaning implement comprising abrasive or non-abrasive fibres, said fibres consisting of a flat element provided with partial cuts and folded about itself, said flat element being connected in that region without cuts to a support element.
