DESCRIPTION

Cleaning unit, comprising a cleaning mop and at least one packaging.

The present invention relates to a cleaning unit, in particular for cleaning clean rooms, which contains a cleaning mop and a packaging.

Cleaning companies use, in particular, multiple cleaning mops in particular for floor cleaning. These cleaning mops are provided, as a rule, for repeated use, that is, after each cleaning cycle, the cleaning mops must be washed. Especially for cleaning mops, which are used for cleanroom cleaning, not only precautions and special precautions should be taken during manufacturing, transport and storage, but also during cleaning of used cleaning mops . The effort to be made in relation to cleaning mops of this type is then increased again for those mops that are used for cleaning sterile spaces, in particular sterile clean rooms.

In EP 382 691 A1 a package for a cleaning mop or the like is disclosed which contains, in addition to this cleaning mop, also a container with a liquid composed of a cleaner and / or disinfectant. This cleaning liquid is present in the packaging, therefore, separately from the cleaning mop. The liquid container can be opened without tearing the packaging. In other words, a soaking of the cleaning mop takes place within this package. This provides a cleaning mop that can be stored for a very long period of time and that can be impregnated with the cleaning liquid just a little before use.

Document DE 200 05 016 U1 refers to a cleaning cloth for business use purposes, consisting of a ready-made carrier material and a cleaning medium applied thereon, the carrier material being soaked with a predetermined amount of cleaning medium. In addition, a package for the mentioned cleaning cloths is described in document 200 05 016 U1. This packaging can be a heat-welded sheet, which surrounds the cleaning cloths, which is in a dimensionally stable housing with a socket opening. In this way it is intended to avoid touching the cleaning medium and wetting a cleaning cloth or spraying a cleaning medium.

Therefore it would be desirable to be able to resort to cleaning mops that do not suffer from the disadvantages of the prior art.

The invention therefore posed the problem of providing cleaning systems that enable reliable, at the same time economic, cleanliness of cleanrooms and / or sterile spaces.

Accordingly, a cleaning unit was found according to the characteristics of the patent 1.

Thanks to the fact that the cleaning mop is already completely soaked in the packaging, in particular a plastic sheet packaging, it can be used, after removal of the packaging, directly for cleaning, without the need for another wet or other soaked with additional cleaning liquid. Therefore, during cleaning of the cleaning unit according to the invention, regular cleaning carts can be dispensed with which, as a rule, also contain at least one container with cleaning liquid. It is also possible, without more, to have an influence, for example, through the volume of the packaging, on the quantity of liquid systems packaged therein. At the same time, the packaging is, in general, sized in such a way that the entire volume of the packaging is not filled with liquid and cleaning mop (s), but also inside it there is also air (cleaned) or an inert gas. This allows the cleaning unit according to the invention also, without having to provide cleaning liquid by means of separate containers or buckets, being able to provide enough liquid for cleaning also of large surfaces of a space to be cleaned, in particular of a White room. In particular, the amount of cleaning fluid optimally adjusted for a cleaning task can always be used. The cleaning liquid is thereby dosed correctly.

In a structuring of the cleaning unit according to the invention there is not only a soaked individual mop therein, in particular a flat mop, but there are, within it, two or more mops, in particular flat mops one on top of the other. . Depending on the use and / or size of the cleaning mop, for example, 3, 4, 5, 6, 7 or also 8 up to 20 mops, in particular flat mops, may be provided in the first packaging of the cleaning unit. cleaning according to the invention.

In a particularly suitable structure, the cleaning mop of the cleaning unit according to the invention is a flat mop. The flat mops generally have a rectangular base surface and are equipped with a cleaning or front side and a cover or back side. These cleaning mops have, advantageously, on the cover or back side, of at least one lace bag, preferably two lace bags, for a cleaning mop holder. These cleaning mop bras are

connected, most of the time, through a joint with a stick or a handle, so that larger surfaces can also be cleaned without further use by using the cleaning unit according to the invention.

The cleaning unit according to the present invention is particularly suitable for use in the cleaning of clean rooms. Accordingly, the cleaning mop, in particular the flat mop, of the cleaning unit according to the invention is also a cleanroom mop. With the cleaning unit according to the unit it is possible not only to immediately provide a cleaning mop, which can be used during the cleaning of clean rooms, but at the same time the liquid system necessary for it, for example in the form of a cleaning liquid or a disinfection liquid. In this way, the effort to provide a suitable cleaning liquid as well as the suitable containers for housing this cleaning liquid for cleaning of cleanrooms can be significantly reduced. Fundamentally, the external supply of a cleaning liquid can be dispensed with the use of the cleaning unit according to the invention.

The cleaning mop that is used with the cleaning unit according to the invention is suitably a single-use cleaning mop, in particular for cleaning cleanrooms. Thanks to the fact that the cleaning mop is made as a single-use cleaning mop, that is to say that the cleaning mop does not have to be manufactured and provided so that it has to endure without variation the 50 to 60 washing cycles usually required, the costs that occur with the manufacture of the cleaning unit according to the invention can be kept in a frame.

It has been shown as particularly suitable to resort to cleaning units according to the invention of this type, in particular also for cleaning cleanrooms, which have at least one more plastic foil packaging, in particular liquid-tight, in the one that is packaged in the first plastic foil packaging, in particular liquid-tight, preferably by welding.

On the one hand it is possible by means of this variant embodiment, in the case of leaks of the first packaging, in particular a plastic foil packaging, to prevent an exit or contamination of the environment with the liquid system. Since this can be retained in the second plastic sheet packaging, which surrounds the first plastic sheet packaging. It is also provided by using another package, which surrounds the first package, in which the liquid system is, a cleaning unit, which can be used in a particularly efficient and practicable way for cleaning cleanrooms. The outer packaging can be removed, for example, in a sluice zone in the transition to the cleanroom, so that it is ensured that only one packing arrives inside the cleanroom, along with the cleaning liquid and mop cleaning, that satisfies the conditions of the space. In particular when the cleaning unit comprises a first packaging and another second packaging, a very effective cleaning of sterile spaces as well as clean rooms can be guaranteed. At the same time, the second outer packing is usually removed in a first sluice. In this context it is advantageous that the first inner packaging, which is in the other or second outer packaging, containing the cleaning mop and the liquid system, is in cleaned or sterilized air. In other words, the inner packaging has already been introduced and closed, under clean room conditions or low sterile conditions, in the outer packaging. Only in a second sluice, the inner packaging is immediately removed, so that only the cleaning mop impregnated with the liquid system reaches the sterile space or the white room. Alternatively, it is also possible to disinfect or re-sterilize the inner packaging in the second lock, to take it inside the space to be cleaned.

At the same time it can be provided in a suitable embodiment that the first and / or the other, second, plastic foil packagings, are formed as a hose and because the welds are preferably in each case on the narrow sides opposite each other from the plastic sheet hose.

In the case of the liquid system of the cleaning unit according to the invention it may be, for example, an aqueous system, which in particular contains at least one disinfection medium, in particular i-propanol and / or ethanol, and / or at least one means of cleaning, in particular biocide. Accordingly, in the case of the liquid system it may be a cleaning liquid or a disinfection liquid. Obviously it is also possible that the liquid system is, at the same time, a cleaning and disinfection liquid. Suitable cleaning liquids may be alkaline or acidic adjusted. Alkaline-adjusted cleaning fluids are frequently used when grease dissolution properties are required. Acid adjusted cleaning liquids are generally used to remove traces of lime and / or oxide. Cleaning liquids within the meaning of the present invention characterize, as a rule, that they contain, in an aqueous system, a surface active agent. Suitable surface active agents for cleaning cleanrooms or cleaning sterile spaces are known to the person skilled in the art. Suitable disinfection liquids are, as a rule, liquid systems which are equipped, for example, with a biocidal, bactericidal, sporocidal and / or fungicidal action. For use in clean rooms as well as for cleaning uses, as a general rule, cleaning liquids or disinfection liquids are used in the case of which, in the case of used water, deionized water or quality water WFI For cleaning

Sterile spaces have been subjected to water from suitable cleaning and disinfection liquids, preferably to a filtration process (0.2 | jm).

For disinfection liquids within the meaning of the present invention used in sterile spaces, aqueous systems are preferably used which contain alcohols such as i-propanol and / or ethanol, peroxides, peracids such as acetic acid, ammonium compounds such as benzalkonium, guanine derivatives or chlorine-based compounds such as chlorine dioxide, sodium hypochlorite, chlorhexidine, chloramine T

As a means of disinfection particularly suitable for cleaning clean rooms as well as for cleaning sterile spaces, an aqueous system, containing 70% vol. of i-propanol and 30% in vol. of water.

The particularly suitable cleaning units according to the invention are also those that can be used for cleaning sterile spaces, in particular sterile clean rooms. With the cleaning units according to the invention it is possible, in a particularly simple and reliable way, to move into the sterile space cleaning mops together with cleaning liquid in a previously sterilized manner. This is true, in particular, for the cleaning units in which the soaked cleaning mop that is in a first package, in particular a plastic sheet package, is enclosed in at least one other package, in particular a packaging of plastic sheet.

The methods for sterilizing the cleaning unit according to the invention, together with the cleaning mop and the liquid system inside, are known to the person skilled in the art. For this, one can resort, for example, to sterilization by beta radiation, gamma radiation and / or electron radiation.

With the cleaning units according to the invention, cleaning mops can be used reliably in sterile environments, without thereby having to accept losses in terms of sterility. With the cleaning units according to the invention a sterility safety level (SAL value) can be maintained which is not above 10-6 That is to say that between 1,000,000 cleaning units according to the invention are contaminated, on average, only one with a viable germ. For example, it must be, according to the European Pharmacopoeia, the SAL value for Parenteralia of at most 10-6

For the cleaning units according to the invention, it may be provided in a preferred embodiment that the flat mop has at least one front or cleaning side layer and at least one rear side layer or on the side of the cover, as well as, where appropriate, of at least one central intermediate layer, disposed between the front side and the rear side layer, at least one or more being provided on the rear side preferably several lace bag (s), for a flat mop bra.

At the same time, cleaning units are particularly preferred, in which the flat mop has a front or cleaning side with an open loop or loop structure (from the German, "Besatz-oder Schlingenstruktur") and a back side or covering, comprising the front side and the back side, at least, a woven, knitted or knitted layer formed of microfiber material or comprising the front side, at least, a woven front side layer, of gender of knitted or knitted formed by microfiber material and comprising the back side, at least, a back side layer made from a nonwoven material, in particular solidified, comprising or consisting, in particular, of polyolefin fibers, in particularly, in polypropylene fibers.

It can also be provided at the same time that said at least one intermediate layer, disposed between the front side layer and the rear side layer, comprises or consists of a non-woven material, in particular non-solidified, or a foam material .

Also particularly suitable are those cleaning units in which cleaning mops are used in which the front side and / or rear side layer of microfiber material has a weight per square meter of at least 150 g / m2 or in the range from 150 a / m2 to 400 g / m2, preferably at least 200 g / m2 or in the range from 200 g / m2 to 350 g / m, and particularly preferably at least 225 g / m2 or in the range from 225 g / m2 to 300 g / m2, and / or in which said at least one intermediate layer has a weight per square meter in the range between 50 g / m2 and 150 g / m2 , preferably in the range between 75 g / m2 and 125 g / m2 and, particularly preferably, in the range between 90 g / m2 and 110 g / m2.

Said at least one intermediate layer may also be, e.g. ex. a punched nonwoven fabric. In addition, the fibers of said at least one intermediate layer may be cut fibers, in particular with an average length in the range between 20 mm and 80 mm, preferably in the range between 30 mm and 70 mm and, particularly preferred, in the range between 40 mm and 60 mm.

With the use of a flat multilayer mop as a cleaning mop for the cleaning unit according to the invention said at least one back layer is a spinning veil material. This backside layer is also formed, particularly preferably, with a single layer.

In the suitable flat mop the front side layer and the back side layer or the front side layer, the intermediate layer and the back side layer are connected to each other along the perimeter edges by an overlock sewing process. It can also be provided, at the same time, that the lace bag or the lace bags have been obtained by folding one or more edge sections of the flat mop, so that in the area of the lace bag or the Lace bags the material of the back side layer rests on each other. Alternatively, the edge sections can be folded over each other connected to each other, along their perimeter edges, with the formation of the lace bag by overlock sewing processes.

The front side layer suitably has an average thickness of at least 0.5 mm or in the range of 0.5 mm to 0.5 mm, preferably at least 1.0 mm, or the range from 1.0 mm to 4.5 mm, and particularly preferably, of at least 1.5 mm or in the range between 0.5 mm and 5.0 mm. The intermediate layer preferably has a thickness in the range between 0.5 mm and 10 mm, preferably from 1.0 mm to 8 mm and, particularly preferably, in the range between 2.0 and 5 mm .

The invention was based on the surprising knowledge that cleaning mops, in particular for commercial cleaning in a practical and economical way, can also be provided in particular for commercial cleaning. With the cleaning units according to the invention it is possible to completely dispense with an additional impregnation, wetting or soaking of the cleaning mops. Rather, the optimum amount necessary for the corresponding cleaning process of the liquid system, such as cleaning and disinfection liquid, can be provided immediately. It is also advantageous that any effort for conditioning a cleaning mop that should be used for cleaning is suppressed with the cleaning unit according to the invention. This has a very advantageous effect, in particular during cleanroom cleaning as well as cleaning sterile spaces. In this way, no cleaning mops, disinfection or cleaning means or containers for disinfection or cleaning means or transport vehicles must be provided in a manner suitable for sterile spaces or clean rooms. Rather, care must be taken only that the cleaning units according to the invention, whether they contain a single package or a system, in which the cleaning mop is, together with the liquid, in another packaging, the second, are manufactured and They are packed under clean or sterile room conditions. The risk of contamination is thereby significantly reduced or even eliminated completely.

As a further advantage, it has been found that with the cleaning units according to the invention, in particular those containing single-use cleaning mops, e.g. ex. single-use flat mops, clean, very reliable and pollution-free cleanliness of clean rooms is achieved. In particular for the cleaning of sterile spaces, including sterile clean rooms, very high standards can be guaranteed with the cleaning unit according to the invention. In this way it is possible to avoid contamination or loss of sterility already during the manufacture and packaging of cleaning mops both during the manufacture of the packaging as well as the liquid system. For example, it can be ensured, during commercial cleaning, that the standards for clean room and / or sterility are not breached. This eliminates the need to provide external cleaning liquid and have to fill or transfer them in containers. The procedures mentioned last often lead to pollution problems, particularly when they are not breached, even slightly, with the required care.

It has been proven on many occasions how to structure the cleaning mop as a single-use cleaning mop, for example when it is made in the form of a flat mop. Cleaning mops that are used for cleaning units according to the invention, in particular flat mops, can be used again

for cleaning, obviously, after removal of the packaging and use for cleaning, after going through a cycle of washing or decontamination. It is also possible to use cleaning mops of this type, which are intended as single-use mops for cleaning clean rooms or cleaning sterile spaces, after a cycle of washing or decontamination, at least again for cleaning of spaces, which are not 5 white rooms or that should not be kept sterile.

The features of the invention that have been disclosed in the above description and in the claims may be essential, both individually and in any arbitrary combination, for the realization of the invention in its different embodiments.
