Definitions

  • the invention relates to a flat mop cover according to the preamble of patent claim 1.
  • a flat mop cover for mounting on a mop cover holder which has an elongated base body, wherein the base body has a first elongated surface and a second elongated surface, which are opposite to each other.
  • the two elongated surfaces are each designed as cleaning surfaces. These surfaces are a surface to be cleaned, such as a floor, alternately assignable.
  • the two cleaning surfaces are arranged such that between them, a plate-shaped support member of a mop cover holder is sandwiched.
  • the plate-shaped support members are resiliently reversibly changeable, for example, in length and can be inserted into a pocket of a flat mop cover of the type described above and fixed non-positively and positively.
  • fixation of support element and flat mop cover can also be done only positively, for example via friction. However, this offers less security against loosening of the flat mop cover from the support element in comparison to the above-mentioned non-positive and positive fixation.
  • a clean room is understood as meaning a room in which the particles in air are controlled in terms of size and number.
  • the DE 44 27 672 C2 a flat mop cover made of two layers of a nonwoven fabric, between which a layer of a particularly absorbent material, such as viscose or foam of any fiber composition is added.
  • the layers of nonwoven fabric are sewn to the absorbent material with the absorbent material received in sewn-away pockets.
  • longitudinal seams are provided, which extend along the cleaning surfaces.
  • the flat mop covers In clean rooms, it is necessary that the used flat mop covers do not tend to form particles. Furthermore, the flat mop covers must show the most uniform possible release of liquid, for example, to ensure the so-called contact time of the disinfectant in the disinfection of floor or wall surfaces. Contact time is the time that elapses between application of a liquid film to its partial or complete evaporation. Only in this time, the disinfectant solution can work.
  • the invention is therefore the object of a flat mop cover of the type mentioned in such a design and further, that can be easily cleaned with this in a clean room surfaces to be cleaned.
  • the main body must serve as a liquid reservoir in order to store a relatively large amount of liquid. It has been recognized that the body must deliver the stored liquid as evenly as possible and metered to a surface to be cleaned.
  • the main body contains a liquid, in particular a liquid provided with a disinfectant Save large dimensions and this must be able to deliver evenly and continuously to a surface to be cleaned over a longer lasting wiping process.
  • the flat mop cover can be used in two ways. On the one hand, it can be in dry form and can be subjected to a certain amount of cleaning liquid on site and shortly before the cleaning process, for example in a dosing tank. After cleaning, the flat mop cover is discarded in a separate container, after which either cleaned, in particular washed, or disposed of.
  • flat mop covers can be pre-soaked in a box by, for example, simultaneously dousing them with a defined amount of cleaning liquid. Thereafter, the pre-moistened mop covers are transported on a trolley to the place of cleaning and mounted there each for cleaning on the mop cover holder. After cleaning is done with the flat mop covers as mentioned above. These can be washed or disposed of.
  • a foam is used which has no fibers. As a result, contamination of an atmosphere of a clean room is effectively avoided.
  • the foam layer could be flat continuous. For cost reasons, it is advantageous not to interrupt the foam layer. Furthermore, it is conceivable that drainage holes are provided in the region of a lower, closed surface of the flat mop cover. Against this background, the foam layer on the two cleaning sides of the flat mop cover is designed to be continuous over at least 90% of its height. The remaining 10% of the height can be used for drainage holes.
  • a foam layer has proven to be particularly absorbent. Moreover, a foam layer that does not have fibers is prone to particle or fiber release. Foams are inexpensive to produce in almost any shape and are characterized by a high fluid absorption capacity. In addition, foams are soft, elastic and readily adjustable in terms of their liquid uptake or release capacity. This can be done by suitable adjustment of the porosity. Specifically, an open-cell foam could be used which does not consist of fibers or has such.
  • the base body could have at least one inner foam layer, the outside of which is connected to at least one cover layer by knitting.
  • the cladding layer can take on abrasive properties, wherein in the inner foam layer, a liquid reservoir is provided.
  • the base body could have at least one inner foam layer, wherein on the surfaces to be cleaned zuwendbaren outside a further textile outer layer is applied.
  • the foam core has no separate outer layer and only the foam core comes into direct contact with the ground.
  • this outer layer can have special properties for cleaning or abrasive dirt removal.
  • An envelope layer in the sense of this document is therefore not necessarily a textile structure which exists separately without the main body.
  • knitting does not create a separate textile structure, but only a textile surface, namely an associated with the foam layer envelope layer.
  • a textile outer layer may consist in particular of microfibre threads or yarns, preference being given to using so-called filament yarns of endless filaments in order to prevent particle release in the event of fiber breakage.
  • the outer cleaning surfaces could not be connected to the extent by stitching with the foam layer. It is concretely conceivable that the surfaces by stitching (English term: "stitch bonding") with the foam layer are connected. Sewing on a genuine, separate cover layer or detergent is associated with extra expense and expense. Furthermore, the cladding layer or the cleaning agent can slip against the foam layer rather. Although the slippage can be prevented by multiple, for example, longitudinally extending fixation seams are used. Moreover, there is a risk of damaging a usually very thin cleaning agent. This damage can be caused by protrusions and bumps in the ground.
  • the main body could have at least one inner foam layer, on the outside of which at least one covering layer is laminated over its entire area or over a large area.
  • a lamination process is inexpensive to carry out.
  • Lamination is usually over the entire surface, but can also be done over a grid or stripes only part of the area. It is also conceivable to use a bonding method, e.g. by applying so-called hot melts. As a result, two nonwoven fabric layers can be connected without affecting the water balance. A so-called hot-melt is applied, for example, in thin spiral lines.
  • a lamination produces a chemical bond between a foam and a coating layer or a foam and a foam without further adhesives.
  • Lamination with the aid of an adhesive or sticking would create a barrier between the outer skin and the foam. This would prevent liquid from flowing in or out. In that regard, this barrier would create a kind of check valve, which prevents fluid flow.
  • a flame lamination technique uses an extremely large amount of heat to chemically alter or bind materials to bond.
  • the base body is sealed. By sealing edges and corners of the body can be generated, which release only a small amount of particles.
  • the main body could have at least one inner foam layer, on the outside of which at least one cladding layer is mounted.
  • a coating layer can be provided with an elastic band and pulled like a stocking over the core of the body.
  • the foam layer could have a thickness of 5 to 15 mm. Such a thickness has been found to be advantageous in absorbing and defining liquid in a defined manner.
  • Each elongated surface could each face or be associated with a foam layer or part of the foam layer. This ensures that a foam layer of 5 to 15 mm in thickness can be applied to a surface to be cleaned.
  • the main body can be turned attached to the mop cover, so that only one elongated surface facing a floor and then the other elongated surface.
  • the floor facing a foam layer with a thickness of 5 to 15 mm, wherein between the foam layer and the floor, the cladding layer is arranged.
  • the two elongated surfaces could accommodate a pocket for receiving a support member between them.
  • a variable in length wiper plate as for example from the DE 10 2005 012 491 A1 is known to be easily introduced into the flat mop cover.
  • a mop cover holder could include a flat mop cover of the type described herein.
  • Such a mop cover holder comprises a mop plate, to which a preferably gimbal-hinged handle or a handle is attached. With such a mop cover, a surface, in particular a floor, can be cleaned.
  • Such a mop cover is preferably used in a clean room use.
  • a clean room is understood as meaning a room in which the particles in air are controlled in terms of size and number.
  • the body Due to its high absorption capacity, the body can absorb a very large amount of liquid and these defined, even and metered deliver to a surface to be cleaned.
  • the entire flat mop cover can be used as a disposable product, which is suitable only for single use, or as a half-disposable product, which is suitable for use only a few times.
  • the entire flat mop cover can be produced, washed, sterilized and sterile packed to meet the high requirements in clean rooms for sterility and the lowest possible particle release. Before use, the entire flat mop cover is soaked in a liquid.
  • the base body has a core of at least one foam layer whose outer sides have a textile cleaning surface.
  • the outside is covered by a cover layer of nonwoven fabric.
  • the cladding layer can be connected to the core by lamination, knitting or by frictional engagement.
  • Fig. 1 shows a flat mop cover 1 for placement on a mop cover holder 1a, comprising an elongate base body 2, wherein the base body 2 has a first elongated surface 3 and a second elongate surface 4, which face each other, wherein between the elongated surfaces 3, 4 at least one foam layer. 6 is arranged, and wherein the two elongated surfaces 3, 4 are each formed as cleaning surfaces and arranged such that between them, a plate-shaped support member 5 of a mop cover holder 1a is sandwiched.
  • the base body 2 at least four times and at most twenty times its dry weight of liquid is reversibly absorbable, the foam layer 6 having no fibers.
  • the base body 2 has at least one foam layer 6.
  • the foam layer 6 is flat connected.
  • the main body 2 has only an inner foam layer 6, the outside of which is provided with at least one envelope layer 7.
  • the shell layer 7 can be sewn, laminated on the foam layer 6 or mounted on the foam layer 6.
  • the foam layer 6 has a thickness of 5 to 15 mm.
  • Each elongated surface 3, 4 is each an area of the folded foam layer 6 facing or assigned.
  • the two elongated surfaces 3, 4 receive a pocket 8 between them for receiving a support element 5.
  • Fig. 1 shows a mop cover holder 2, wherein the mop cover holder 1 a as a support member 5 has a mop plate on which a not shown stem is gimbals arranged via a hinge 9.
  • Fig. 2 and 3 show that the single, integrally formed foam layer 6 is folded over so that it extends over both elongated surfaces 3, 4.
  • a recess 10 is introduced, in which the joint 9 can be inserted together with the support member 5.
  • the main body 2 is due to the elongated slot-like recess 10 pivotable about the hinge 9 so that either the elongated surface 3 or the elongated surface 4 is alternately assigned to a not shown floor or a surface to be cleaned.
  • the concrete embodiment shows a so-called double-sided flat mop cover 1 with a core of a foam layer 6, wherein the foam layer 6 has no cleaning side, but only serves as a water reservoir.
  • the actual cleaning surfaces are the surfaces 3, 4, which are formed by the cladding layer 7.
  • a thin coating layer 7 of a cleaning fabric preferably made of nonwoven fabric or microfibers, laminated or applied by knitting.
  • the English term for knitting is stitch-bonding.
  • Either a thin PES (polyester) nonwoven layer is applied to the foam layer 6 by flame lamination, or a microfiber layer producing two and a half dimensions is stitched by knitting.
  • a thin PES (polyester) nonwoven layer is applied to the foam layer 6 by flame lamination, or a microfiber layer producing two and a half dimensions is stitched by knitting.
  • By knitting does not create a smooth, closed surface, such as in a woven textile, but it can also small loops are formed, which protrude from the substrate. This can be done very inexpensively.
  • the foam layer 6 is formed continuously and not in longitudinal pockets, as in Fig. 1 or 2 of the DE 44 27 672 C2 shown, recorded.
  • the two elongated surfaces 3, 4 of the flat mop cover 1 are not at its two short end faces by a seam as in the DE 44 27 672 C2 connected, but the foam is welded or glued or otherwise connected cohesively.
  • the welding can be done by ultrasound. This is cost effective and ensures lower particle release for cleanroom applications.
  • the upwardly facing edges of the two elongated surfaces 3, 4 are not specially sewn or sealed, but are open.
  • the laminated or effectively sewn enveloping layer 7 extends around these edges except for the insides of the Bag 8 still around to allow even at these points still cleaning a skirting board.
  • Fig. 4 shows a sectional view of the flat mop cover 1, wherein within a core of a single contiguous foam layer 6 sandwiched a support member 5 is added. To the support member 5 is connected via a gimbal joint 9, a stem 11. The foam layer 6 has on its outer sides an enveloping layer 7.
