Abstract

Device for disinfecting contact surfaces, characterized in that the device contains a functional unit (10) comprising a refillable reservoir (1) and a reusable disinfection tip (2).

Description

The invention relates to a device for disinfecting contact surfaces.

The disinfection of contaminated surfaces is an essential protective measure against pathogens that are transmitted via jointly used contact surfaces. Indirect contact infection, also known as smear infection, affects mankind worldwide, currently particularly in the Covid-19 pandemic, through the transmission of the SarsCov2 virus via shared contact surfaces.

The currently most common solution is disinfection with spray disinfectant and a wipe or with a disinfectant wipe, for example to disinfect handles on shopping trolleys. Both solutions have the disadvantage that they generate a very large amount of waste, which can also be infectious. Some shopping trolleys have a disinfection ring attached to the handle, which the user slides over the handle for disinfection. The disinfection ring, however, is touched by hundreds of customers every day and is itself a source of infection. Grab bars in public transport are touched by thousands of people every day even during the Covid-19 pandemic, without disinfection taking place. The same applies to treadmills on escalators, keyboards in elevators or ATMs, fittings in rental cars, to name just a few examples.

US 2008006309 A1 describes a stationary washing line for shopping trolleys. However, the shopping trolleys have to drive through the car wash after each use, which would consume large amounts of water and generate equally large amounts of waste water.

CN 102241357 A describes a stationary device for the continuous disinfection of escalator handrails.

In CN 111473258 A describes a mobile, pen-type and UV-based sterilization device. The efficiency is questionable, however, since the elimination of different pathogens requires different UV wavelengths. In addition, the range of applications is limited due to the small size of the device and there is a potential risk if UV sterilizers are used on a large scale in public.

CN 111281997 A describes a mobile disinfection pen. The head of the pen is used to touch buttons and keys. When the cap is on, the head is disinfected using a cotton ball soaked in disinfectant and located in the cap. An integrated spray element allows the spray disinfection of small areas, eg door handles.

This device is less used for surface disinfection, which here also requires the use of wipes.

There is a lack of technical solutions for a mobile and flexible disinfection device for the end user for the universal, careful, sustainable and risk-free disinfection of contact surfaces that are used in public by a large number of people and are sources of transmission of viral and bacterial germs and associated diseases.

The invention is based on the object of creating a disinfection device which, while avoiding contact chains, is used exclusively by the user.

Another object of the invention is to provide a mobile and reusable disinfection device with a small size and a low weight.

The invention is also based on the object of creating a disinfection device which does not produce any waste in the disinfection process and is therefore sustainable.

The invention is based on the additional object of creating a disinfection device which can be adapted to the size and shape of the surfaces to be disinfected.

The invention achieves these objects in that the device contains a functional unit comprising a refillable reservoir and a reusable disinfection tip.

The reservoir of the functional unit can supply the disinfection tip with disinfectant. The user can disinfect the contact surface by wiping it over with the disinfectant-soaked disinfectant tip. The disinfected contact surface can be used after a short drying time. The reservoir and the disinfection tip work together as a functional unit of the device for disinfecting a contact surface. Wiping or wiping can be dispensed with, which means that wiping cloths can be saved in a sustainable manner. If a disinfectant level is low, the user can refill disinfectant. After refilling, the device can be used again with the reusable disinfection tip. In this way, a mobile and reusable device can be provided that does not produce any waste in the disinfection process and is therefore sustainable.

The subclaims provide advantageous design options for the disinfection device.

The device, in particular the outer surface of the reservoir, is preferably accessible from the outside by the user during the disinfection process; contact of the user's hands with a disinfectant which tends to have a drying effect can be avoided.

The disinfection tip is advantageously designed to be variable. The variably designed disinfection tip of the functional unit makes it possible to use differently designed disinfection tips 2 together with the reservoir. In this way, the functional unit can be individually adaptable to the shape, the contour of a contact surface to be disinfected and / or an application task.

In a further development of the invention, the reservoir and the disinfection tip are not permanently connected to one another. The reservoir and the disinfection tip can in particular be connected to one another in a detachable manner. When a disinfectant level is low, the user can separate the disinfection tip, which is detachably arranged on the reservoir, from the reservoir. The reservoir can easily be refilled with disinfectant. After refilling, the reservoir and the disinfection tip can be connected to one another again and can be used again for disinfection.

The reservoir and the disinfection tip are preferably connected to one another by means of a plug connection, screw connection or other mechanical connection. The reservoir and the disinfection tip can be reliably connected to one another via a plug connection, a screw connection, a slide-in connection, a tongue and groove connection or some other detachable mechanical connection. A detachment of the disinfection tip during disinfection from the reservoir can be counteracted. In particular, a leak-proof storage of a liquid disinfectant can be made possible by a liquid-tight connection between the reservoir and the disinfection tip.

For connection to the disinfection tip, the reservoir can have a, in particular funnel-like, cover for receiving the disinfection tip. By means of an adapter-like cover, the reservoir can have a disinfection tip with a smaller diameter and / or a different cross-sectional geometry. The reservoir with the cap can be designed in at least two parts. In this way, the disinfection tip can be connected to the cap before or after it is arranged on the rest of the reservoir.

In a further development of the invention, the disinfection tip has a disinfection sponge and an outer connecting element, which is formed in particular in the area of the base of the disinfection sponge. The disinfectant sponge can absorb disinfectant from the reservoir. In this way, the disinfectant sponge can be soaked with disinfectant without this having to be applied to the disinfectant sponge or the contact surface to be disinfected from the outside of the device. The upper side of the disinfectant sponge soaked with disinfectant can be brought into contact with a contact surface for disinfection. During disinfection, the disinfectant sponge can easily apply disinfectant to the contact surface. The disinfection tip can be connected to the reservoir in a simple manner via the outer connection element. The outer connection element can be directed towards the outside of the disinfection tip in order to enable a connection to be established via the outside of the disinfection tip. For example, the outer connecting element can be designed as an outer plug connection, in particular in the manner of a bulge, a pin or a groove.

According to one embodiment, the functional unit has one or two disinfection tips. Two disinfection tips enable the user to choose which of the two disinfection tips he will use for disinfection. The disinfection tips can form diametrical ends of the functional unit. For this purpose, the disinfection tips can be arranged on diametrical sides, in particular front sides, of the reservoir. The two disinfection tips can differ in their shape, their material and / or the disinfectant.

The functional unit preferably has disinfection tips with differently shaped top of the disinfection sponges. The shape of the upper sides of the disinfection sponges can each be designed for the disinfection of a specifically shaped contact surface. The device can be used for disinfecting differently shaped contact surfaces by means of several disinfection tips with differently shaped upper sides of the disinfection sponges. For disinfection, that disinfection tip can be selected whose disinfection sponge has a surface shaped to disinfect the respective contact surface.

The variably designed disinfection tip advantageously cleans small or large ones Contact surfaces. The device can be used variably with the disinfection tip in different applications.

In one embodiment of the invention, the disinfection tip is in one piece. A one-piece disinfection tip can easily be made from one material.

According to a structural embodiment, it is proposed that the one-piece disinfection tip consists of a disinfection sponge and an outer connecting element formed on its base. The outer connection element is directed towards the outside of the disinfection tip so that it can be accessed from the outside when a connection is established. The outer connecting element formed on the base of the disinfecting sponge consists as a component of the one-piece disinfecting sponge from the material of the disinfecting sponge. The outer connecting element formed on the base of the disinfecting sponge enables a large part of the disinfecting sponge to protrude from the reservoir in order to be able to be brought into contact with the contact surface for disinfection.

In a further embodiment of the invention, the disinfection tip is in several parts. A multi-part disinfection tip can be manufactured in a simple manner in terms of manufacturing technology, in particular from different materials. A component of the disinfection tip can be used for mechanical connection and / or mechanically stabilize the disinfection tip. Another component of the disinfection tip can take up the disinfectant for application to a contact surface, in particular absorb it.

According to a further structural embodiment, it is proposed that the multi-part, in particular two-part, disinfection tip consists of a disinfection sponge and a separate external connecting element fastened to its base. The disinfecting sponge and the separate outer connecting element can be easily joined together to form the disinfecting tip. The outer connecting element fastened to the base of the disinfecting sponge can make it possible for a large part of the disinfecting sponge to protrude from the reservoir in order to be able to be brought into contact with the contact surface for disinfection. The disinfectant sponge and the outer connecting element can be made of different materials.

The outer connecting element is advantageously molded on, molded in or glued on. A molded-on, molded-in or glued-on connecting element can be attached to the disinfection sponge in a simple manner.

The disinfection tip, in particular the disinfection sponge, is advantageously made of an absorbent and mechanically resilient material. An absorbent material can allow easy and long-lasting soaking with disinfectant. With a mechanically resilient material, a mechanically stable disinfection tip can be achieved which essentially does not deform during disinfection. With a mechanically stable disinfection tip, contact surfaces can be disinfected precisely. Even when disinfecting round objects, precise disinfection can be achieved with a mechanically stable disinfection tip, since this essentially does not deform during disinfection.

Preferably the material is porous, washable and reusable. With a material with a porous structure, an absorbent disinfection tip, in particular an absorbent disinfection sponge, can be achieved in a simple manner. A washable material that is not destroyed during or after a washing process can be freed of impurities by washing and reused after washing. In this way, the service life can be extended in an environmentally friendly manner.

It is also advantageous if the material consists of natural fibers or chemical fibers, in particular fiber sponge based on polyester, sponge rubber based on natural rubber or pore foam. With a fiber sponge based on polyester, a sponge rubber based on natural rubber or a pore foam, capillary forces for absorbing the disinfectant into the disinfecting sponge and for its permanent wetting can be achieved in a simple manner. By using a pore foam, a mechanically stable disinfection sponge and, in particular, a mechanically stable disinfection tip can be achieved.

The disinfecting sponge particularly preferably varies in width and shape. By varying its width and shape, the disinfection sponge can be adapted to the reservoir for connection to it and / or to the width and shape of the contact surface to be disinfected.

According to one embodiment, the top of the disinfection sponge is smooth, concave or asymmetrically curved. Thanks to the smooth, concave or asymmetrically curved upper side, the disinfectant sponge can easily be used to disinfect a specific, be designed in particular complementary, shaped contact surface. A disinfecting sponge with a smooth top can be used to disinfect a flat or smooth contact surface, for example to disinfect an ATM keypad, escalator straps or armrests. A disinfecting sponge with a concave top can be used to disinfect a contact surface of a round object with a small diameter, for example to disinfect a handle in local public transport or a handle on a shopping cart. A disinfecting sponge with an asymmetrically curved top can be used to disinfect a contact surface of a round object with a larger diameter.

It is also advantageous if the disinfection tip, in particular the disinfection sponge, is washable and reusable. The entire disinfection tip can be washed for cleaning. There is no need for the disinfection tip to be broken down into its individual components beforehand. Washing can remove impurities from the disinfection tip, such as dirt particles picked up during disinfection. The disinfection tip can be reused after washing. In this way, the service life of the disinfection tip can be extended in an environmentally friendly manner.

The disinfection tip, in particular the disinfection sponge, can consist of a temperature-resistant material, in particular a hard foam. In particular, a hard foam, such as a pore foam, can have a higher temperature resistance than a soft foam. The disinfection tip made of temperature-resistant material can be cleaned at higher temperatures, for example washed in a dishwasher. Before the disinfection tip is reused, in particular after the device has been refilled with disinfectant, the disinfection tip can be cleaned in this way to dissolve dirt and destroy germs.

In one embodiment of the invention, the interior of the reservoir stores a disinfectant which is in direct contact with the underside of the disinfection tip. The disinfection tip can take up the disinfectant directly from the reservoir via its underside. For this purpose, the underside can be diametrically opposite the upper side of the disinfection tip, in particular of the disinfection sponge, which can be brought into contact with the contact surface. Due to the direct contact of the underside with the disinfectant, the disinfection tip can automatically soak itself with disinfectant. In this way, the disinfectant can be directed out of the reservoir via the disinfection tip. The interior of the reservoir can store the disinfectant in a freely flowing manner in the manner of a tank, the fill level in the reservoir decreasing during the disinfection. If the reservoir is not completely filled with disinfectant, the direct contact can only be present in that position of the device in which the disinfection tip for disinfecting a contact surface in the gravitational field is located below the reservoir. In this position, gravity allows the disinfectant to flow in the direction of the disinfection tip, which creates direct contact. In this way, the supply of the disinfection tip is ensured during the disinfection process as long as the reservoir still contains disinfectant.

Furthermore, it can be advantageous if the device carries a disinfection tip and the disinfection tip is connected in a liquid-tight manner via an external plug connection at its base to a terminal, complementary plug connection of the reservoir, in such a way that a functional unit consists of reservoir and disinfection tip, the interior of the Reservoir stores a disinfectant which is in direct contact with the underside of the disinfection tip and wets it into the outer surfaces of the disinfection sponge, and the outer sides of the reservoir serve as a grip surface in the disinfection process, and the wetted outer surfaces of the disinfection sponge form contact with the contact surface to be disinfected .

It can also be advantageous if the device carries two disinfection tips and the disinfection tips are each connected in a liquid-tight manner via an external plug connection at their base to a terminal, complementary plug connection of the reservoir, such that a functional unit consists of a reservoir and two disinfection tips, the The interior of the reservoir stores a disinfectant which is in direct contact with the undersides of both disinfection tips and wets them into the outer surfaces of the disinfection sponges, and the outer sides of the reservoir serve as a grip surface in the disinfection process, and the wetted outer surfaces of one of the disinfection sponges make contact during the disinfection process to form the contact surface to be disinfected.

In a preferred embodiment, the interior of the reservoir has an absorbent storage medium for storing the disinfectant. Direct contact of the disinfectant with the underside of the disinfection tip can also be achieved without the effect of gravity. The Storage medium can hold the disinfectant like a tampon. The disinfection tip can be supplied with disinfectant from the storage medium via its underside by the acting capillary forces. Disinfection in an overhead position of the device, in which the disinfection tip for disinfecting a contact surface in the gravitational field is located above the reservoir, can be made possible. An external force acting on the reservoir, such as compression to convey the disinfectant in the direction of the disinfection tip and in particular into the disinfection tip, can be dispensed with by using the storage medium.

The storage medium can consist of a washable, reusable and / or porous material. The storage medium can be made of polyethylene terephthalate (PET) or polyethylene (PE). Alternatively, the storage medium can be made of the same material as the disinfection sponge and / or in one piece with the disinfection tip, in particular the disinfection sponge. For stabilization, the storage medium can have a cover made of a different material, in particular made of polypropylene (PP).

In a further embodiment, the reservoir, in particular the interior of the reservoir, has a spring mechanism for pretensioning the storage medium in the direction of the disinfection tip. The spring mechanism can exert a pretensioning force on the storage medium in the direction of the disinfection tip in order to ensure permanent contact between the storage medium and the disinfection tip. The spring mechanism can be designed in such a way that the prestressing force exerted on the storage medium does not compress the storage medium. The spring mechanism can have a spring acting on the storage medium, in particular a leaf spring or a spiral spring. The spring can be made of a plastic so that it is not attacked by the disinfectant.

In an advantageous embodiment, the disinfection sponge has a contact surface that is beveled with respect to the top side. Due to the beveled contact surface, a large-area contact can be achieved between the contact surface to be disinfected and the disinfection sponge when the disinfection tip is placed on the contact surfaces at an angle. The top side can be an end face of the disinfecting sponge, in particular of the entire functional unit. The contact surface can be an inclined surface on the side of the disinfection sponge. The contact surface can extend in the transition between a side surface and an end surface of the disinfection sponge in the manner of a bevel. The contact surface can run transversely to a disinfection direction, in particular along the width of the disinfection tip. The disinfection direction is the direction along which the disinfection sponge is moved over the contact surface during the disinfection process.

It is also advantageous if the width of the upper side of the disinfecting sponge, transverse to its disinfection direction, is greater than the overall height of the functional unit. The disinfection direction is the direction along which the functional unit is moved over the contact surface during the disinfection process. The overall height of the functional unit corresponds to its extension along the connecting axis between the reservoir and the disinfection tip. In comparison to the overall height of the functional unit, a wide upper side used for disinfection can be provided in this way. With this surface, the contact area can be disinfected over a wide area. Even larger contact areas can be completely disinfected with just a few pulls.

In this context, it is particularly advantageous if the width of the top of the disinfecting sponge is greater than or equal to 2 cm, preferably greater than or equal to 5 cm, particularly preferably greater than or equal to 10 cm.

It is possible for the reservoir to have a grip piece for providing a grip surface for a user during the disinfection process and a receiving piece that can be connected to the grip piece for receiving the disinfection tip. In this way, the reservoir can be configured in several parts. By exchanging the handle, the handle surface of the functional unit can be adapted. To refill the reservoir, the handle piece and the receiving piece can be separated from one another. Refilling by separating the handle piece from the receiving piece can be provided as an alternative or in addition to refilling by separating the disinfection tip from the reservoir. The interior of the reservoir can be accessed in a simple manner by means of a receiving piece which is detachably connected to the handle.

The storage medium of the reservoir can be exchangeable. An exchangeable storage medium can enable the reservoir to be refilled quickly by replacing an old storage medium with a new storage medium soaked with disinfectant. For example, the storage medium can be accessible from the outside for exchange by detaching the handle from the receiving piece.

According to a structural embodiment, the reservoir, in particular the handle, an essentially constant width over its length. The handle with a substantially constant width can be held more easily and stably during the disinfection process. To accommodate the closure cap during the disinfection process, in which the closure cap does not cover the disinfection tip, the grip piece can have a step with a substantially constant width at the end area opposite the disinfection tip.

According to a further structural embodiment, the reservoir has a depth that varies in the longitudinal course. In the depth, the reservoir and in particular the handle can be tailored in this way. A tapered grip allows a more secure gripping and prevents the grip from slipping out of the user's hand.

The term “contact areas” used above and below describes areas that are touched by a large number of people in public and thus sources of transmission viral and bacterial germs and related diseases, especially Covid-19. The contact surfaces include, for example, keyboards and buttons, in particular on ATMs, elevators and computer keyboards; Handles, in particular door handles, grab handles in public transport, handles on shopping trolleys, device handles in sports studios; other contact surfaces in public facilities such as restaurants, in particular tables, seats and armrests; Fittings and controls in motor vehicles, in particular rental cars.

In 1 to 3 the essential structural features of the disinfection device according to the innovation are shown in simplified form. The device consists of the three components reservoir 1 , Disinfection tip 2 and cap 3 as in the 1a and 2a shown. In the embodiment shown here, the three components are oval-shaped, see 3a and 3b . The reservoir 1 and the disinfection tip 2 are connected to one another in a liquid-tight manner and form a functional unit 10 for storing a suitable liquid disinfectant, see hatching in 1c . The reservoir is stored here 1 most of the liquid disinfectant, while the absorbent disinfectant tip 2 is soaked in disinfectant. In an embodiment not shown, the reservoir is 1 additionally procure with an absorbent storage medium to store disinfectant.

A cap 3 closes the disinfection tip 2 outwards, see in 1a and 1c , and prevents both unintentional contact of the user with the disinfectant and the disinfection tip from drying out 2 . The cap 3 carries a bracket on its back 7th with terminal formation 8th after the cap is completely on 3 on the disinfection tip 2 a complementary notch 9 in the reservoir 1 and a falling off of the cap 3 from the disinfection tip 2 prevented like that 1a and 2a clarify. 1a shows the additional breakpoints 4th the bottom of the cap, which is in complementary receptacles on the reservoir 1 grab, cf. 1c .

A disinfectant tip 2 can be made up of one or two parts. In the one-piece embodiment, cf. 2c , the upper part is a disinfectant sponge 5 and the subcomponent located on the base is an external connector 6-1 procured from the same material in one form. In the two-part embodiment, not shown, there is the outer plug connection 6-1 made of a different material than the disinfection sponge and is molded, molded or glued to the base to provide a complete disinfection tip 2 to train.

The outer connector 6-1 serves as an external connecting element 6-1 while the reservoir 1 an inner connector 6-2 like an inner plug connection 6-2 has, which with the outer connecting element 6-1 for connecting the disinfection tip 2 with the reservoir 1 cooperates.

1c shows that the disinfection tip 2 with the reservoir 1 is connected, shown in hatching. This is done in the reservoir by capillary forces 1 stored liquid disinfectant in the disinfectant sponge 5 sucked and wets it permanently. The disinfectant sponge 5 is passed over the surface to be disinfected during the disinfection process. It consists of an absorbent, elastic material with sufficient stability. Thus the disinfectant sponge wets 5 a contact surface evenly and withstands the mechanical forces that occur during wetting. It is a washable and reusable, porous material, for example made of natural fiber or chemical fiber, including a fiber sponge based on polyester, or a sponge rubber based on natural rubber, or a pore foam.

The material nature of the disinfectant sponge 5 is not restricted to the aforementioned materials; rather, all materials known to the person skilled in the art can be used.

The functional unit 10 from reservoir 1 and disinfection tip 2 is easy to separate and depending on the application, one of the variably designed disinfection tips is used 2 with a specific shape of the disinfectant sponge 5 used. Some embodiments of variably designed disinfection tips are shown in FIG 4th shown. Disinfectant sponges 5 with a concave top 5-1 , see. 4a , are suitable for disinfecting round objects with a small diameter, for example handles in local public transport or handles on shopping trolleys. Disinfectant sponges 5 with a smooth top 5-1 , see. 4b , are used to disinfect smooth surfaces, for example on an ATM keypad, on escalator straps, or on armrests. In a preferred embodiment not shown, the disinfecting sponge is 5 widened, for disinfecting larger surfaces, e.g. table surfaces. Disinfectant sponges 5 with asymmetrically curved top 5-1 , see. 4c , are used to disinfect round objects with a larger diameter.

The effortless exchange of a disinfection tip 2 takes place by loosening the plug, screw or other mechanical connections between the reservoir 1 and disinfection tip 2 . In the embodiment in 2c carries a one-piece disinfectant tip 2 an external connector at its base 6-1 . This is in the upwardly open side of the reservoir 1 into a complementary inner plug connection 6-2 firmly plugged in, as from the 3a and b can be seen.

The outer connector 6-1 is like a circumferential bulge of the disinfection tip 2 designed. For connecting the disinfection tip 2 with the reservoirs 1 engages the outer connector 6-1 an inner plug connection designed to be complementary to it 6-2 of the reservoir 1 on.

In an embodiment not shown, the disinfection sponge 5 an additional round-shaped perforation. The surface of a ballpoint pen is disinfected by passing through this perforation. The ballpoint pen can pass through the holes in the disinfection sponge 5 be passed through so that its peripheral surface through the disinfectant sponge 5 is wetted with disinfectant for disinfection.

In a further preferred embodiment, not shown, there is a spring-mounted disinfection tip 2 the reservoir 1 put on. When putting on the cap 3 becomes the disinfection tip 2 into the reservoir 1 countersunk and when removing the cap 3 extended again.

The reservoir 1 serves on the one hand to store disinfectants, on the other hand, with its outer surface, forms the grip surface of the user during the disinfection process. The disinfection device on the reservoir is used for surface disinfection 1 held in hand and the disinfectant sponge 5 placed on a surface to be disinfected and guided over it under slight pressure. Just the disinfectant sponge 5 forms contact with the surface to be disinfected, wets it, captures germs and disinfects the contact surface. At the same time, the user avoids direct contact with the surface to be disinfected and with the disinfection sponge 5 . After the disinfection process, the disinfection tip 2 with the cap 3 locked. The user can use the disinfected contact surface after a short drying time; no wiping is required. On the disinfectant sponge 5 adhering germs are still exposed to the action of the disinfectant and are eliminated.

The disinfection device can be reused as often as required. When there is a low level of disinfectant in the reservoir 1 the user separates the disinfection tip 2 from the reservoir 1 and refills disinfectant. After reclosing, the device can be used again immediately.

The disinfection tip 2 is washable. There is no germ load, since adhering germs permanently impair the effect of the disinfectant in the disinfectant sponge 5 are exposed. The cleaning of a disinfectant tip 2 preferably takes place after several disinfection processes or when the reservoir is refilled 1 : the user disconnects the disinfection tip 2 and reservoir 1 and cleans the disinfection tip 2 , for example in a dishwasher or a separate cleaning bath.

The 5 and 6th show a further preferred embodiment of the disinfection device according to the invention with a second disinfection tip 2 . This is the first disinfection tip 2 identical in structure and of the same type in the opposite free end of the reservoir 1 integrated, as in the 5a , 5b and 6a made clear. In 5d this embodiment carries disinfection tips 2 with differently shaped top 5-1 the disinfectant sponges 5 : concave and smooth. An exchange for disinfection tips 2 with a different shape or size of the disinfectant sponge 5 takes place depending on the nature and size of the surfaces to be disinfected.

In 7a to 7c an embodiment is shown in which the reservoir 1 in addition, an absorbent storage medium 1-1 for storing disinfectants. Even if it is only a functional unit 10 with a disinfectant tip 2 shown can be absorbent storage media 1-1 also in an embodiment with two disinfection tips 2 be used. Each disinfection tip can 2 its own absorbent storage medium 1-1 be assigned so that the disinfection tips 2 be able to use a different disinfectant for disinfection.

As in 7a can be seen, the storage medium is standing 1-1 with the bottom 2-1 the disinfection tip 2 in direct contact. That in the storage medium 1-1 stored disinfectant can therefore be sent directly to the bottom 2-1 the disinfection tip 2 be handed in. The bottom 2-1 the disinfection tip 2 can also use the underside of the disinfectant sponge 5 be. Unlike in 1c , in which the interior of the reservoir 1 is designed as a tank with disinfectant flowing freely in it, the disinfectant is in the reservoir 1 of the 7th in the storage medium 1-1 bound recorded.

From the cap 3 the disinfection tip is covered 2 to recognize. While the height of the entire device from the reservoir 1 and the attached cap 3 is specified, corresponds to the overall height H the functional unit 10 the expansion along the connecting axis between the reservoir 1 and the disinfection tip 2 . As in 7a shown, the height falls H the functional unit 10 therefore less.

In 7b and 7c is the storage medium 1-1 partly from the rest of the reservoir 1 shown pulled out. To get disinfectant in the reservoir 1 refill, this can either be on the storage medium 1-1 be poured or a new storage medium pressed with disinfectant 1-1 be inserted.

In the 7th shown disinfection tip 2 has no external connecting element 6-1 on. Around the disinfection tip 2 with the reservoir 1 to connect, these are designed to fit. The disinfection tip 2 is therefore due to clamping forces on the reservoir 1 held. Nevertheless, the disinfection tip 2 also with an external connecting element 6-1 be provided.

As in the other embodiments, the reservoir 1 over its length L. an essentially constant width B1 on. This way the reservoir can 1 can be manufactured comparatively easily, for example from plastic in an injection molding process.

As the cap 3 the disinfection tip during the disinfection process 2 does not cover, the flap could 3 laid during the disinfection process. To avoid this, the reservoir points 1 at that of the disinfection tip 2 opposite end area a step with reduced width B1 and depth T for holding the cap 3 on. The closure cap can be used at this stage 3 be plugged in during the disinfection process so as not to be misplaced. This level represents the only minimal variation in width B1 of the reservoir 1 represents, which essentially continues to have a constant width B1 having.

Unlike the disinfectant sponges described above 5 assign the in 7th disinfectant sponges shown 5 an additional one, across from the top 5-1 sloping contact surface 5-2 on. Even if the disinfection tip 2 is placed at an angle during the disinfection process, so that the reservoir 1 is guided not essentially at right angles, but at an acute angle to the contact surface, is due to the beveled contact surface 5-2 is a large area of contact between the contact surface to be disinfected and the disinfection sponge 5 . The contact area 5-2 represents a transition between the side face along the width B5 the disinfection sponge 5 and the top 5-1 as the face of the disinfection sponge 5 is therefore the contact surface 5-2 in the manner of a bevel on the disinfectant sponge 5 designed.

The contact area 5-2 runs transversely to the disinfection direction D. and along the width B5 the disinfection tip. The direction of disinfection D. is the direction along which the disinfection sponge 5 is moved over the contact surface during the disinfection process.

As in 7d and 7e can be seen, any disinfectant sponge can 5 regardless of the shape of its top 5-1 an additional support area 5-2 exhibit. Even if only embodiments with a single contact surface 5-2 are shown, the disinfectant sponge 5 also two parking spaces 5-2 exhibit. These can be in the transition between two opposite side surfaces and the top 5-1 lie. A disinfectant sponge 5 with two contact surfaces 5-2 can also be designed chisel-shaped in this way and two opposing disinfection directions D. exhibit.

In 8th an embodiment of the device is shown, which is particularly suitable for disinfecting larger surfaces. The direction of disinfection D. along which the functional unit 10 is moved over the contact surface during the disinfection process, runs transversely to the long side of the device according to FIG 8th .

The width B5 the top 5-1 the disinfection sponge 5 across the direction of disinfection D. is greater than the overall height H the functional unit 10 . Compared to the overall height H the functional unit 10 In this way, a wide top can be used for disinfection 5-1 to be provided. With this surface 5-1 the contact surface can be disinfected over a wide area. With just a few pulls along the disinfection direction D. , between which the functional unit 10 across the disinfection direction D. is offset on the contact surface, larger contact surfaces can also be disinfected over the entire surface.

The reservoir 1 is in 8th designed in three parts. In addition to the storage medium 1-1 it has a handle 1-2 to provide a grip surface for the user during the disinfection process and one with the handle 1-2 connectable receiving piece 1-3 to accommodate the disinfection tip.

The handle 1-2 can be interchangeable, so the grip surface of the functional unit 10 adapt.

For refilling the reservoir 1 can use the handle 1-2 and the recording piece 1-3 separated from each other and so the storage medium 1-1 uncover. The storage medium 1-1 can then continue to hold in the handle 1-2 or recording piece 1-3 arranged to be soaked with disinfectant. The storage medium can also 1-1 and outside the handle 1-2 or recording piece 1-3 soaked with disinfectant or through an already soaked storage medium 1-1 be replaced. These refill options by separating the handle 1-2 from the recording piece 1-3 can alternatively or additionally to refilling by disconnecting the disinfection tip 2 from the reservoir 1 be provided.

To the handle 1-2 with the receiving piece 1-3 to be able to connect, has the handle 1-1 two locking tongues 1-4 on. With these locking tongues 1-4 can the handle 1-3 in corresponding locking recesses 1-5 of the recording piece 1-3 intervention.

Also in 8th shown reservoir 1 and in particular its handle 1-2 points along its length L. an essentially constant width B1 on. The handle 1-2 with essentially constant width B1 can be kept stable during the disinfection process. Unlike the reservoir 1 according to 7th shows that in 8th shown reservoir 1 no step on which the cap 3 could be plugged in during the disinfection process.

The handle 1-2 of the reservoir 1 also has a depth that varies along its length T on. This is how the handle is 1-2 in the deep T waisted. With this tailored grip 1-2 a more secure gripping can be made possible and a slipping out of the handle piece from the hand of the user can be counteracted.

The disinfection tip 2 points in 8th a bar-like shape along its width B5 on. In addition, the disinfection tip 2 formed in one piece. The outer connecting element 6-1 is as a circumferential groove of the disinfection sponge 5 shaped in the area of its base.

The disinfection tip can be used to connect and disconnect 2 about one in depth T running opening in the inner connecting element 6-2 of the recording piece 1-3 pushed in and out of the inner connecting element for replacement 6-2 be pulled out. The inner connecting element 6-2 is equipped in two parts with two guide rails facing each other. The guide rails of the inner connecting element 6-2 run across the entire width B1 of the reservoir 1 . Each of the two guide rails engages the groove-like connecting element from one side like a spring 6-1 on. The connecting element 6-2 in this way holds the disinfection tip 2 on two opposite sides in a form-fitting manner along the longitudinal axis of the reservoir 1 .

The ones in the 1-8 The embodiments shown of the disinfection device according to the invention are oval-shaped. In further embodiments, not shown, the disinfection device consists of each round or corner-shaped component reservoir 1 , Disinfection tip 2 and cap 3 . reservoir 1 and disinfection tip 2 are, depending on the embodiment, connected to one another by a suitable connection.

The oval shape of the in the 1-8 The embodiments of the disinfection device according to the invention shown here are in an oval cross-section transversely to the longitudinal axis of the disinfection device, along which the reservoir 1 and the disinfection tip 2 be in contact with each other.

In 9 is a storage medium 1-1 towards the disinfection tip 2 pre-tensioning spring mechanism 11 shown. Inside the reservoir 1 exercises a feather 11-1 a biasing force on the storage medium 1-1 out. The feather 11-1 initially acts on a pressure plate 11-2 which then applies the pretensioning force to the entire surface of the storage medium 1-1 transmits. This means that there is relatively little pressure on the storage medium 1-1 exercised which the storage medium 1-1 not compressed. In this way, there is no unwanted leakage of disinfectant from the storage medium 1-1 . At the same time, there is permanent contact between the storage medium 1-1 with the disinfection tip 2 ensured.

The disinfection tip 2 has an outer connecting element 6-1 on, which is designed in the manner of two plug-in pins. Here is the outer connecting element 6-1 at the front on the underside 2-1 the disinfection tip 2 arranged. The reservoir 1 however, has an inner connecting element 6-2 on what as in the manner of two blind holes of the storage medium 1-1 is trained. Here is the inner connecting element 6-2 in the direction of the disinfection tip 2 turned face of the reservoir 1 arranged.

The outer connecting element 6-1 works with the inner connector 6-2 in the manner of a positive and a negative of a plug connection, the outer connecting element 6-1 for connecting the disinfection tip 2 with the reservoir 1 into the inner connector 6-2 intervenes. This also creates the interface between the storage medium 1-1 and the disinfectant sponge 5 elevated. The efficiency of the transfer of disinfectant from the storage medium 1-1 over the contact surface onto the disinfection sponge 5 is increased.

The advantages of the disinfection device according to the invention are the exclusive use by the individual user to avoid contact chains; Sustainability by avoiding waste in the disinfection process; small size and weight for mobile use; Targeted use on contact surfaces of various shapes and sizes through the selection of suitable, exchangeable disinfection tips 2 .
