Description

Disinfection device and protective cover with a disinfection device

Technical area

The present invention relates to a disinfection device and a protective cover for a communication device with such a disinfection device according to the respective independent claim.

Background disinfection devices are known.

Usually these are conventional spray cans that are filled with a disinfectant that is released when the spray head is pressed. Furthermore, dispensers are also known which, for example, are set up stationary in hospitals, etc. and which contain a relatively large amount of disinfectant so that they last for a longer period of time during intensive use in frequented environments. These solutions have the disadvantage that they are not suitable as a portable solution because of their size. In addition, dosing can be difficult and in many cases too much of the agent is dispensed with one actuation.

Presentation of the invention

The object is therefore to provide an improved disinfection device. In particular, the object is to provide a disinfection device that is easy to use in the handling, effective, selectively applicable and reusable.

This object is achieved in a first aspect of the invention with a disinfection device according to claim 1. The disinfection device for applying a disinfectant to at least one fingertip of a user accordingly comprises a housing with a recess accessible from the outside through an opening, in which recess the fingertip can be inserted, inside the housing a spray unit and a container for disinfectant fluidly connected to the spray unit. The spray unit comprises a spray head which protrudes into the recess and a valve device fluidly connected to the spray head. The valve device is designed in such a way that when the spray head is actuated by means of the fingertip it releases disinfectant from the container as an aerosol into the recess, so that the aerosol can wet the fingertip. The housing comprises a first section holding the container and a second section for holding the spray unit, the first and second sections being detachably attachable to one another by means of cooperating connecting elements so that the container can be exchanged by releasing the connection between the two sections.

In a preferred embodiment, the recess is filled with a sponge element in which the spray head is completely embedded. In a preferred embodiment, the second section forming the recess is immovable and the spray head can be moved relative to the second section when actuated to release disinfectant. In a second aspect of the invention, the object is achieved with a protective cover for a mobile communication device, in particular for a mobile phone or a tablet. In an area facing a rear side of the communication device, the protective cover comprises an integrated disinfection device for applying a disinfectant to at least one fingertip of a user. The disinfection device comprises a container for a disinfectant integrated in the protective cover, a spray unit fluidly connected to the container, the spray unit including a spray head and a valve device fluidly connected to the spray head. The protective cover has a recess which is accessible from the outside through an opening, in which the spray head protrudes and in which a fingertip of the user can be received. The valve device is designed in such a way that when the spray head is actuated by means of the fingertip it releases disinfectant from the container as an aerosol into the recess, so that the aerosol can wet the fingertip.

The present invention in both aspects has the advantage that a user can use the disinfection device if necessary in any situation in which there is a risk of contamination and possible infection with pathogens in daily life due to the frequent inevitable contact with objects, and this quickly and can be done selectively, in that it can be used simply for disinfecting a single finger and in that undesirable large-area disinfection is avoided. The design of the disinfection device as a two-part device also ensures that the container with the disinfectant is easily exchangeable.

Both aspects of the invention cover the disinfection of the user himself, for example before and / or after pressing a button, e.g. when operating an ATM or buttons in elevators, where there is a high risk of

Pathogen contamination exists as it can be used by many people, disinfect the finger that came into contact with the button. So if a button of such a device is pressed, the user can then use the disinfection device to

Disinfect the fingertip used to operate the button. All he has to do is press the spray head briefly with the fingertip in question so that disinfectant can wet the fingertip and thus disinfect it. In addition to the obviously simple use, the disinfection device has the further important advantage that it only has to be used selectively for the affected fingertip. As described above, conventional devices often dispense too much disinfectant to be caught in the hand, and it can also drip onto the floor, which is a waste of disinfectant. It is also disadvantageous that with the liquid agent in hand, the whole hand or both hands must be disinfected by rubbing in. The present disinfection device avoids these disadvantages, which saves a large amount of disinfectant, since precisely for the scenario described only a small portion of a hand (the fingertip) actually comes into contact with the potentially contaminated button and has to be disinfected. Last but not least, it is also of great advantage that, especially with frequent disinfection, the drying of the hands, the As is known, frequent disinfection of the hands with agents typically containing alcohol is largely avoided.

The second aspect of the invention has the additional advantage that it offers a portable disinfectant solution which is already integrated in an object that is used daily. Since a mobile phone is a constant companion nowadays, the integration of the disinfection device in the protective cover of the mobile phone leads to an effective disinfection solution without the need to carry an additional device.

Disinfection device from FIG. 7. Ways of carrying out the invention

Fig. La and lb are explained together below. They show a disinfection device la with a housing 6, a spray unit 8 and a container 7 for disinfectant, which with the

Spray unit is fluidly connected.

For all embodiments and aspects of the invention, the housing 6 has a first, the

Container 7 holding section 6a and a second section 6b holding the spray unit 8, wherein the first and the second section can be fastened to one another in a separable manner by means of cooperating connecting elements 9. By releasing the connection between the two sections, the container becomes accessible and can be exchanged. It is preferred if the cooperating

Connecting elements form a screw cap. But you can also create a snap-in connection. However, it is also possible that the first section 6a of the housing itself is the container, which has connecting means (e.g. threads) for connection to the second section 6b of the housing, which results in a saving of material for the housing material.

To operate the spray head to dispense disinfectant, the spray head is by means of Finger tip in the direction of the valve device from a basic position in which the valve device is closed into a spray position in which the valve device is open and releases disinfectant from the container. The spray head automatically returns to its home position without external actuation.

The container for disinfectant is preferably refillable. It is fluidly connected to the spray unit 8. Fluid-connected means in the entire present context that liquid can penetrate from the container into the spray unit. The container may be a pressurized container and used with propellant, or it may be a conventional container such as a perfume bottle in which the spray is achieved by pumping air into the interior of the container. For this purpose, the spray unit can be designed in such a way that it continuously releases disinfectant or only releases one dose of disinfectant during a single actuation for the duration of the actuation. The advantage of the first variant is explained in connection with a preferred feature of the second section 6b of the housing in the context of FIGS. 3a, 3b. The second variant is advantageous because a short spraying process is sufficient for one or more fingertips. It is further preferred if the spray unit can release disinfectant upwards or downwards or to the side, which also applies to the disinfection device according to the first aspect of the invention, but in connection with the second aspect of the invention in the context of FIGS. 4a, b in detail is explained.

As can be seen from the synopsis of Fig. La and lb, the user guides the fingertip F in the direction of arrow D through an opening 3 into a Recess 4 of the housing 6 or of the second section 6b of the housing and presses a spray head 2 of the spray unit 8 in the direction of the container 7, which causes the disinfectant to be released as an aerosol 10. This will disinfect his fingertip. Of course, the disinfection device or the recess can be dimensioned in such a way that several fingertips can be inserted into the recess 4 at the same time. The second section forming the recess is preferably immovable and the spray head can be moved relative to the second section when actuated to release disinfectant, which can be seen from the synopsis of FIGS. 1 a and 1 b.

In embodiments, the central axes of the housing 6 and the spray unit 8 and the container 7 can coincide. This simplifies the construction of the disinfection device and saves space. However, it is also conceivable to provide the first section 6a of the housing with the container, e.g. at a 90 ° angle to the second section 6b of the housing.

FIG. 2 shows a detailed sectional view of the disinfection device from FIG. 1 a with the two housing sections 6a and 6b, which are connected by means of connecting elements 9b designed as a screw connection. As mentioned, the first section 6a of the housing here carries the container and the spray unit. The spray head 2 is preferably spherical or elliptical and is fluidly connected to the valve device of the spray unit by means of a tube 2b. The spray head comprises a plurality of nozzles 2a, through which disinfectant can be sprayed into the recess 4. This configuration of the spray head is suitable for all aspects of disinfection Device preferred. It has the advantage that the aerosol is sprayed in many directions and thus a comprehensive disinfection is ensured, which would not be possible to the same extent with a conventional unidirectional spray head due to the limited clearance for the fingertip in the recess 4. However, it should be mentioned in this context that especially in this embodiment the first section 6a of the housing together with the container and spray unit can be unscrewed and provided with a conventional unidirectional spray head instead of the spherical spray head, so that the disinfection device can also be used as a conventional spray can . As mentioned, the spray unit comprises a valve device 9a which, when the spray head is actuated in the direction of the container, enables disinfectant to be dispensed from the latter through the tube 2b into the spray head 2 and through the nozzles 2a as an aerosol into the recess. In particular, it can be

There are embodiments in which the orientation does not matter, that is to say that it is also possible to spray upside down with the disinfection device. The valve device is preferably fluidly connected to a flexible hose 17 which is arranged in the interior of the container and through which disinfectant reaches the spray head when the spray head is actuated. At its free end, the hose has a weight element 18 which is designed such that, as a result of its weight, it is submerged in the disinfectant up to the wall of the container which is closest to the earth, regardless of the orientation of the disinfection device. The weight element is preferably formed by a ball 18, in particular a metal ball, with others Shapes are also conceivable. The ball is preferably enclosed with play in a ball housing provided with holes (not shown), so that when the spray head is actuated, disinfectant flows from the container through the holes in the ball housing between the ball and the ball housing into the flexible hose. This means that the disinfection device can be used in any position and regardless of the filling level.

Fig. 3a and 3b show a side view and a perspective view of a disinfection device according to the first aspect of the invention with additional preferred features.

In this embodiment, the recess is filled with a sponge element 11 in which the spray head is completely embedded. It is preferred if the sponge element is exchangeable. Due to its soft texture, the sponge element contributes to the comfort during disinfection and enables even wetting of the skin area to be disinfected.

Furthermore, in embodiments, the second section 6b of the housing can be designed in such a way that the edge defining the recess is not straight in at least one area 12 but rounded downwards in the direction of the first section 6a. Preferably, two opposite such areas 12 are provided. As a result, the disinfection device can also be used for the disinfection of handles, for example, since the edge of the recess can adapt to the rounded shape of a handle. This is particularly effective in combination with the sponge element 11, since better wetting of the handle can be achieved by means of the sponge element. In this context, there is also an advantage of using one as a pressure vessel Clearly designed container, in which disinfectant is continuously released during a single actuation for the duration of the actuation. In this scenario, the goal is to disinfect surfaces in which the disinfection device is guided on the one to be disinfected, so that several pumping processes during the simultaneous operation would be more cumbersome. This scenario covers an a priori disinfection of an object before it is touched. The disinfection device can thus be used for an a priori disinfection and also for an a posteriori disinfection in which a fingertip is only disinfected after an object has been touched.

In embodiments, the container comprises on its outside an elastic clamp 13, in particular an outwardly curved clamp 13 designed as a leaf spring, for clamping in a cleaning cloth, which clamp is fastened to the housing by means of a fastening element 14. The fastening element divides the clamp, viewed in its longitudinal extension, into an actuating section 13b with a first free end and a holding section 13a with a second free end. The cleaning cloth (not shown) can be clamped in a rest position of the clamp between the second free end and the container wall. The actuating section is longer than the holding section, such that when the clamp in the actuating section is pressed in the direction of the housing, the second end moves away from the housing due to the elasticity of the fastening element, so that the cleaning cloth can be released without being touched by the user and disposed of in this way can be . It is preferred if the holding section faces the recess, while the actuation section faces away from the recess. The reason for this is that the cleaning cloth can be pinched in such a way that it can be without Contact can be placed over the recess or over the Schwammelernent by suitable rotation of the disinfection device. A flat surface can then also be effectively disinfected and finally dropped into a garbage can by pressing on the actuating section. This has the advantage that the cleaning cloth does not have to be touched at any time during disinfection or afterwards. In addition, the clip 13 can also be used as a holding element for the disinfection device and, for example, be clamped onto the belt. It is noted that an alternative clamp is shown in FIG. 2, which can also be used, but is not suitable for disinfection by means of a cleaning cloth.

Fig. 4a and 4b show a rear view and a side view, respectively, of a protective cover 15 according to the second aspect of the invention with a disinfection device. The dashed lines in the figures indicate that the element in question is located inside the protective cover. As mentioned at the beginning, the protective cover is intended for a mobile communication device, in particular for a mobile phone or a tablet. In an area facing a rear side of the communication device, it comprises an integrated disinfection device for applying a disinfectant to at least one fingertip of a user. The disinfection device comprises a container 16a for a disinfectant integrated in the protective cover and a spray unit 16b fluidly connected to this container. The spray unit comprises a spray head 16c and a valve device 16d which is fluidly connected to the spray head. The protective cover has an opening from the outside accessible recess in which the spray head protrudes and in which a fingertip of the user can be received, which is indicated by the arrow x. The valve device is designed in such a way that when the spray head is actuated by means of the fingertip it releases disinfectant from the container as an aerosol into the recess so that the aerosol can wet the fingertip, which is illustrated in FIG. 4b.

In a preferred embodiment, the container of the disinfection device of the protective cover further comprises a container that is fluidly connected to the container

Refill valve 20 for refilling disinfectant into the integrated container, the refill valve being connected to a flexible hose 20a which protrudes into the integrated container. The refill valve is designed in such a way that it can be opened by a suitable attachment of a refill container to fill the integrated container and closes again automatically as soon as the refill container is removed. In this way, the disinfection device of the protective cover can advantageously be refilled.

As an alternative or in addition, the container of the disinfection device of the protective cover comprises a refill closure 21 which, for refilling the disinfectant into the container, releases a filling opening of the container without valves. This variant advantageously enables the container to be refilled from any refill container without a special valve-opening attachment.

The container of the disinfection device of the protective cover preferably further comprises a vent valve which connects the integrated container to the environment for venting (not shown). In this aspect of the invention, too, the recess is preferably filled with a sponge element (not shown) in which the spray head is completely embedded. The sponge element is also preferably exchangeable.

The protective cover further preferably comprises a cover cap (not shown) for the recess, so that the spray head is protected and is not accidentally actuated. The cover cap can also be provided for the disinfection device according to the first aspect of the invention.

In embodiments, the protective cover is double-walled at least in the area of the integrated container for receiving the integrated container. This is advantageous as additional security against leakage of the disinfectant. In this embodiment, the integrated container can preferably be exchangeable. Alternatively, the protective cover is at least partially double-walled and a corresponding space itself forms the integrated container. With this alternative, no additional container is advantageously necessary, the protective cover in this case of course being made of a material that is impermeable to the disinfectant.

Furthermore, the protective cover preferably comprises a chamber for storing keys 22 or drinks opener 23 or the like, which can be folded out for use (indicated by the arrow y). It can also comprise a ring 23, which is explained in more detail in connection with FIG. 6.

Fig. 5 shows an application example of the disinfection device according to the first aspect of the invention. This is a mascot for Children and can serve as an educational measure to introduce children to the concept of disinfection. In this application, the housing is formed by the mascot. The first portion 6a holding the container is formed by the head of the mascot. The second portion 6b for holding the spray unit is formed through the body of the mascot. The first and the second section can be detachably fastened to one another by means of cooperating connecting elements 9, so that the container can be exchanged by releasing the connection between the two sections.

6 shows a further embodiment of the disinfection device according to the first aspect of the invention. For the protective cover according to the second aspect of the invention, this concept has already been indicated in connection with FIG. 4a, the use of the ring of the protective cover being the same, as described below. Here a ring 23 is attached to the housing 6, the ring having a diameter such that it can be pulled over a handle 25, in particular a door handle, in order to operate the handle without direct contact by the user. The ring is also designed in such a way that it does not leave any scratches on the operated handle. For this purpose, it can be coated with a rubber layer, for example. The use of such a ring is advantageous for the scenario of disinfecting door handles, since these can have very different shapes and, for example, can be comparatively strongly curved and can have widely varying diameters. The diameter of the ring is therefore chosen to be very generous, as can be seen in the figure, so that as far as possible every type of grip can be grasped by the ring. It is also very easy to pull the ring over the handle in this way. Fig. 7 shows a disinfection device 1b in an embodiment in which an adapter element is provided which can be fastened to the housing of the disinfection device and FIG. 8 an application example of the disinfection device from FIG. 7. The scenario already described in the context of the explanation of the downwardly rounded edge of the recess from FIGS. 3a, b dealt with round surfaces to be disinfected, for example handles in a public transport system. In this embodiment, flat surfaces are taken into account, for example in the

Disinfection of a toilet seat surface 26 of a toilet 27. The following explanations can of course be applied to other flat surfaces such as tables or chairs.

The adapter element comprises a rigid extension element 30 protruding into the recess for actuating the spray head and at least one passage opening towards the object. When the spray head is actuated by means of the extension element by pressing the housing in the direction of the surface to be disinfected, disinfectant arrives from the recess through the passage opening onto the surface. As an alternative to the extension element, the disinfection device comprises an alternative spray head which can be plugged onto the spray head or which can be connected to the valve device instead of the spray head. The alternative spray head protrudes out of the opening when it is attached or when it is connected to the valve device, so that it can be used by pressing outside the recess. This embodiment is basically applicable to all embodiments of the disinfection device, including the protective cover. The adapter element from FIG. 7 further comprises a plate-shaped support element 28, by means of which the disinfection device can be displaced back and forth on a flat surface of the object to be disinfected (arrow x in FIG. 8) in order to disinfect the surface. The support element 28 can also be curved in order to be used on a surface that is also curved. On a surface facing the object, the adapter element has a layer 29 made of a foamed or sponge-like or rubber-based material or of fleece material for distributing and / or absorbing disinfectant from the surface of the object, preferably with the layer being replaceable by a new layer. This measure further improves the most comprehensive possible distribution of the disinfectant on the surface to be disinfected. In addition, such a layer protects the surface from scratches that could occur due to the back and forth displacement of the disinfection device. In this embodiment of the adapter element 28, the layer 29, for example a rubber layer, is designed as a sector of a circle. In this special embodiment of the layer, it is advantageous that with a suitable direction of displacement of the disinfection device on the surface, ie in a direction in which there is no layer, the layer has the disinfectant already on the surface that was previously sprayed onto it through the passage openings , so that no wet or damp seat is left behind the disinfection device. In addition, in this example the layer also acts as a spacer to the seat surface 26. In this embodiment, the adapter element is preferably designed as a disposable element, since in this scenario there is a very germ-contaminated area. The use as a disposable element is in the In view of the simplicity of the construction of the adapter element as a simple disk, it is nevertheless inexpensive, since this adapter can be cast from plastic in one step and does not have to meet any special requirements in terms of elasticity, etc. on the material side. Alternatively or additionally, only the rubber layer can serve as a disposable element and be replaced. In this context it is noted that the clip described in connection with FIGS. 3 a, b in connection with the cleaning cloth is also viewed as an alternative to the embodiment according to FIGS. 7 and 8, with the advantage that no support element is necessary.

The present invention has a number of advantages over previously known solutions. It offers a high flexibility of use in a wide variety of disinfection _S scenarios were, depending on what a particular situation makes the most sense, which also saves the user time; Disinfection on the user himself or on an object that is to be touched by the user. The disinfection of the fingertips is an a posteriori disinfection that takes place after the touch, while the disinfection of objects to be touched is mainly an a priori disinfection that takes place before the touch. In addition, disinfectant can be saved with the invention and the disinfection on the user himself can be carried out more gently on the hands by only punctually disinfecting the fingertips in question, which actually had contact with a foreign object, so that the skin of the rest of the hand is not attacked will. While preferred embodiments of the invention are described in the present application, it should be clearly pointed out that the invention is not restricted to these and can also be carried out in other ways within the scope of the following claims.
