Definitions

  • the invention relates to a scouring pad consisting of a grip part made of soft foam and a scouring part made of coarse nonwoven material which may contain abrasives and which is provided with a cleaning agent, in particular soap.
  • Scouring pads of this type are known. They consist of a scouring part made of coarse nonwoven fabric made of synthetic fibers, which may contain abrasives, and a sponge layer made of polyurethane foam, viscose or sponge-like nonwoven fabric. Scouring pads made of polyurethane and viscose are particularly popular and are mainly used as pot cleaners or bathroom cleaners.
  • the sponge part and the scouring part are usually produced by gluing the pre-formed layers. Flame-laminated composites are also common.
  • the foam part made of polyurethane is usually passed over open gas flames in a web shape, whereby the surface melts and becomes sticky.
  • the nonwoven web which may or may not contain abrasive material, is then placed on the surface which has become tacky, and is connected to the sponge part by pressing and cooling. The sheet or sheet-like laminate is then cut to the desired formats.
  • the nonwoven layer usually contains abrasives and serves as a scouring medium for cleaning pots, pans and other dishes. Similar scouring pads are used to clean bathtubs and sanitary facilities, but their scrubbing power is generally lower. For cleaning teflonized or other sensitive surfaces, there are also scouring pads without additional abrasives.
  • the handle of the scouring pads serves for wiping and vacuuming, but essentially also as a handle for the scouring fleece attached to it.
  • Scouring sponges loosen the incrustations that are stuck in pans, pots, etc. due to the rough surface of the scouring nonwoven, supported by the abrasive grains contained in the scouring fleece in a purely mechanical way.
  • additional chemical cleaning agents to facilitate the detachment process and, for example, to emulsify fats and oils that are on the dishes.
  • liquid cleaning agents must also be applied to the items to be cleaned or to the scouring pad, so that the user still needs an additional cleaning agent in addition to the scouring pad.
  • Scouring sponges have also become known which contain soap in the scouring part and / or in the handle part. When water enters, a portion of the soap is dissolved, which then supports and reinforces the cleaning effect of the scouring nonwoven fabric while foaming.
  • the soap solution formed by water and soap also penetrates into the pores of the foam plastic handle part and there leads to particularly intensive foam formation in the wrong place.
  • the sponge part is mostly only used as a handle and the presence of foamy, mostly greasy soap is unpleasant and useless at this point.
  • a saponified scouring pad in which the soap is accommodated in a cavity of a foam rubber part provided with production skin.
  • This part serves as a handle and is glued to a production skin-free foam rubber layer as a scouring layer.
  • the production skin thickens and prevents the soap foam from penetrating into the handle.
  • the production skin-free scouring layer is said to be penetrated by the soap foam. Due to the material properties of the foam rubber, only incomplete saponification of the scouring part occurs.
  • the invention is based on the object of developing a "saponified" scouring pad which can be handled cleanly by the grip part remaining free of soap foam when exposed to water.
  • the scouring pad should in particular be designed in such a way that the scouring part does not saponify properly and the detergent supply is not used up prematurely after use due to the unwanted action of retained water.
  • the interface between soap and sponge is largely or even completely sealed, but not the interface between soap and scouring nonwoven.
  • a plastic film is preferred which is cut according to the inserted soap, cleaning paste or the like and which seals this against the handle part.
  • a suitably tailored plastic container is also useful, which also has the task of keeping the handle part free of soap.
  • a waterproof coating of the cavity between the handle part and the scouring part is sufficient.
  • the waterproof coating is based on synthetic resin.
  • the interface is sealed in such a way that foam formation only occurs at the desired location, namely in the abrasive layer made of nonwoven.
  • the scouring part and the grip part are connected to one another by flame lamination or gluing.
  • the sealing film can be attached in a particularly simple manner by inserting one or more film strips, the width of which is narrower than that of the finished scouring pads, between the sponge sheet and the scouring nonwoven sheet during the bonding process, so that bonding - be it by adhesive or by flame lamination - does not occur in the area of the film between the nonwoven fabric and the sponge.
  • 1 shows such a shaped body. Fig. Shows the same molded body with inserted soap.
  • the scouring part 1 is glued to the sponge part 2.
  • the soap 4 is separated from the sponge part by the film 3.
  • the soap in some cases it is desirable for the soap to have a larger hollow volume.
  • the cavity can be milled, melted or burned into the sponge part locally or as a continuous channel.
  • Fig.3 3 shows a sponge part with a groove which is sealed by the film 3.
  • Fig. 4 shows a comparable scouring pad. A groove is incorporated in the sponge part 2 and is sealed off from the scouring part 1 by the film 3.
  • the soap 4 is embedded in the cavity.
  • the coarse abrasive nonwoven fabric which may contain abrasives, is integrated into the handle part by foaming in all over. At least on the support side, the pores of the scouring nonwoven are penetrated with foam, which results in a seal. It is also possible to insert the film provided to seal the soap.
  • At least one channel-shaped cavity is provided for receiving the soap, cleaning paste or the like.
  • the channel is accessible from both sides from the outside, so that soap can be refilled when the first filling is used up. Different types of soap can also be poured in or worked without soap.
  • a cavity or a groove can be milled, melted or burned into the handle part, which is used to hold an additional sealing element, e.g. a plastic container 5 is suitable.
  • an additional sealing element e.g. a plastic container 5 is suitable.
  • a plastic container 5 Such an embodiment is shown in FIG.
  • the container must be designed so that it is open to the nonwoven side so that water can enter and the soap can gradually dissolve.
  • the cavity provided for the soap is always open on the scrubbing fleece side.
  • it can be of any design and can be dimensioned to suit the particular intended use.
  • the handle part is completely or largely sealed off from the soap solution, it generally being sufficient if only the part of the nonwoven / sponge interface located in the area of the soap is sealed off.
