Description

The invention relates to a liquid dispenser, an injection device for injecting a liquid, in particular into a liquid dispenser according to the invention, and a system for moistening, disinfecting and / or cleaning surfaces.

Various means are known from the prior art, such as how you can moisten your skin yourself or how you can provide it with a disinfectant. Small liquid reservoirs containing the respective liquid agent are usually carried for this purpose. These reservoirs, often designed in the form of bottles, must first be opened manually and then the liquid must be applied to the skin. Both hands are often used to rub the liquid agent on the skin, so that the liquid reservoir must first be put away. The liquid reservoir must then be closed. Such devices have the disadvantage that their handling requires a relatively large amount of time and effort and, moreover, simple and uncomplicated availability is not always guaranteed.

For disinfection, it should be noted that the first contact with the liquid reservoir or the corresponding container cannot rule out the possibility of bacteria or viruses being transferred to this container, so that if the liquid reservoir is used by another user, this cannot be prevented comes into contact with the bacteria or viruses. Furthermore, when transporting such liquid reservoirs, it should be noted that they usually have to be held upright in pockets, whereby it is important here that the liquid reservoir does not open accidentally through unintentional application of pressure.

Proceeding from this, the present invention is based on the object of providing a liquid dispenser, an injection device and a system for humidifying, disinfecting and / or cleaning surfaces, with which a corresponding liquid is made available and guaranteed in a simple and inexpensive manner that the liquid can be applied to a surface to be treated.

This object is achieved by the liquid dispenser according to the invention according to claim 1, by the injection device according to the invention according to claim 7 and by the system according to the invention for moistening, disinfecting and / or cleaning surfaces according to claim 10. Advantageous embodiments of the liquid dispenser are specified in the subclaims 2-6. Advantageous embodiments of the injection device are specified in dependent claims 8 and 9.

The features of the claims can be combined in any technically meaningful manner, in which case the explanations from the following description and features from the figures can also be used, which include additional embodiments of the invention.

The invention relates to a liquid dispenser for receiving and dispensing a liquid for moistening, disinfecting and / or cleaning surfaces, in particular hands, the liquid dispenser having a receiving body which forms a substantially closed cavity.

A liquid for moistening, disinfecting and / or cleaning can be received in the receiving body or its cavity. The liquid dispenser has at least one valve element formed by a region of the wall of the receiving body. This valve element is set up in such a way that it forms an opening in the event of a deformation of the receiving body and / or in the event of a deformation-related increase in pressure in the cavity and thus enables a volume flow of the liquid out of the cavity.

The valve element can only be formed by a region of the wall of the receiving body, that is to say that there are no further components for forming the valve element than the material of the wall which forms the valve element.

In an alternative embodiment, an extra valve element is arranged in the wall.

The valve element is a device with which the flow of the liquid through the wall of the receiving body can be controlled.

The deformation of the receiving body takes place by manual squeezing, for example, from a first shape into a second shape, with the volume of the cavity possibly being reduced at the same time.

Any reduction in the volume of the cavity leads to an increase in pressure in the cavity and consequently to the fact that liquid is pumped out of the cavity at a sufficiently high pressure.

The liquid dispenser according to the invention has the advantage that it depends on the The material used and its wall thickness of the receiving space releases the openings of the valve elements when squeezed or changed in shape and thus enables the liquid to pass out of the cavity to the surface of the wall of the receiving body. In this way, depending on the design of the valve element, the receiving body itself can also be moistened, so that the hands pressing the receiving body are also moistened. Depending on which liquid is contained in the cavity, this liquid can then be used, namely only to moisten surfaces, in particular human skin, or else to provide skin areas with a disinfectant.

In particular, the hands can be provided with a disinfectant very easily and playfully. The liquid dispenser according to the invention also has the advantage that its surface itself is provided with the disinfectant or cleaning agent and the liquid dispenser is thus very clean or disinfected. Accordingly, the liquid dispenser can also be passed on to other people without hesitation, since they do not run the risk of being impaired by dirt or bacteria or viruses on the surface of the wall.

In one embodiment it is provided that the receiving body has exactly one valve element. This valve element serves to dispense the liquid as well as to feed the liquid into the receiving space. This valve element can be designed as a closure element that differs optically and / or haptically from the wall of the receiving space, with which an opening in the wall of the receiving space can be closed and opened in the event of a pressure difference and / or insertion of a cannula or a tip.

The liquid dispenser is set up for filling and thus also for refilling and thus represents a reusable, sustainable product.

In an alternative embodiment, a respective valve element is designed as a recess or an incision in the wall which forms the opening when the wall area having the valve element is stretched due to deformation. In the event of greater deformation, tensile stresses prevail in the wall, which lead to an expansion of the wall, so that a puncture made therein experiences an opening. An incision also creates an opening, in particular when the tensile stress acts with a component perpendicular to the direction of the cut.

Several punctures or incisions can be implemented in the receiving body, a combination of punctures or incisions not being excluded.

The direction of extension of the recess or incision from the outside of the receiving body to the inside of the receiving body can run at an angle, in particular at an acute angle or at right angles, to a radial relative to the center of gravity of the volume of the receiving body. This means that in this embodiment a relevant puncture or incision runs obliquely through the wall of the receiving body. This configuration largely prevents the liquid from splashing out of the receiving body inadvertently.

In a further advantageous embodiment of the liquid dispenser, it is provided that an anchoring part of a baffle element is passed through the valve element, in particular in the area that can form the opening due to the deformation, the baffle element having a baffle surface on the outside of the receiving body, which the area of the opening covers or covers, so that liquid emerging from the receiving body is diverted from the baffle.

This also prevents the liquid from splashing out of the receiving body. This ensures that the liquid that emerges remains essentially on the outer surface of the receiving body and can be applied from there to the object to be moistened or disinfected. In particular, the impact element with an anchoring part can be guided directly through the opening, or through a puncture or incision. Due to the easy deformability of the receiving body, despite the anchoring part being passed through the puncture or incision, the opening resulting from deformation or pressure increase can be sufficiently large that a sufficient volume of liquid emerges from the cavity of the receiving body.

In an advantageous embodiment it is provided that the impact element is connected directly to the anchoring part. To prevent the impact element from being unintentionally detached from the surface of the receiving body, in a further advantageous embodiment the impact element has at least one barb on its anchoring part which engages in the wall or engages behind or undercuts the wall in the cavity.

In this case, a respective anchoring part can simultaneously serve as a tool for producing a respective valve element in the production of the receiving body, in that the anchoring part is pressed or pushed into the closed surface of the receiving body and penetrates the wall of the receiving body in such a way that when the receiving body is deformed and / or the pressure in the receiving body is deformed, the opening is formed on or around the anchoring part.

However, an alternative embodiment is also not excluded, in which the impact element only comprises the impact surface which is materially connected to the surface of the receiving body. If necessary, this baffle surface can also have been produced as an integral part of the surface in the same manufacturing step as the entire receiving body, e.g. during injection molding.

In a special embodiment, the liquid dispenser is designed in such a way that the wall area having the valve element has essentially the same surface structure as the remaining surface of the receiving body.

This means that the valve element or a relevant opening is made in a smooth surface of the receiving body if this is also otherwise made with a smooth surface.

The valve element or the opening formed thereby are therefore also not spaced apart from the remaining surface of the receiving body.

The liquid dispenser according to the invention is relatively easy to deform. In particular, it is provided that the receiving body is designed in such a way that it can be deformed manually with a degree of deformation p, where: p> 0.2 and p <-0.2.

This means that the receiving body changes at least one dimension by a maximum of 20% when a squeezing grip force of 10 N is applied manually to the receiving body.

The receiving body is essentially elastically deformable. However, the invention also includes an embodiment in which the deformation can be carried out essentially plastically.

In particular, the receiving body can be made of a flexible, deformable plastic or a rubber. The thinner the wall thickness of the wall, the easier the deformability of the receiving body. The volume of the receiving body preferably does not exceed 250 cm ³ .

In particular, it is provided that the receiving body essentially has the shape of a sphere. The spherical shape has the advantage that such a receiving body has a maximum volume with a minimal surface area, so that any change in shape automatically leads to a volume minimization and consequently to an increase in pressure and tensile load on the wall of the receiving body, so that with a corresponding distribution of the valve elements at least one opening of a valve element is realized will.

In an alternative embodiment, the receiving body can also have a barrel shape or the shape of a cylinder, with such rotationally symmetrical shapes having the advantage that rolling movements can be performed with the receiving body on the surface to be cleaned or disinfected.

Furthermore, the liquid dispenser is advantageously designed if the receiving body has a plurality of valve elements distributed over its entire surface, in particular evenly distributed.

In a ready-to-use embodiment, a liquid is already received in the receiving body for moistening, disinfecting and / or cleaning. The liquid is a liquid that can be used for different purposes. The liquid can have a different viscosity. It can simply be a humidifying agent, but also a disinfectant and / or cleaning agent.

In a further advantageous embodiment of the liquid dispenser, a porous mass, such as a sponge, which can be soaked with the liquid, is received in the cavity of the receiving body. This serves to ensure that, in the event of a deformation of the receiving body, the liquid received in the porous mass can only flow out of the valve elements at a relatively low speed, thus preventing a large amount of splashing out.

Alternatively or in addition, a support structure can also be introduced into the cavity of the receiving body, the maximum radial extension of which is less than that of the cavity in the unloaded state and / or which has a higher compressive strength than the wall of the receiving body, so that when an from the outside on the Receiving body acting compressive force of the receiving body is only deformed as far as the support structure allows. This embodiment is also intended to prevent the liquid from splashing out far, since, due to the support structure, deformation of the receiving body can only occur to a limited extent.

Another aspect of the present invention is the use of the invention Liquid dispenser for applying a liquid to a surface, in particular for applying a liquid to the human skin by manually changing the shape of the receiving body or increasing the pressure in the receiving body.

In addition, the receiving body of the liquid dispenser can have a first magnetic element.

The liquid dispenser can furthermore have a holding device with a second magnetic element, the two magnetic elements being designed and arranged in such a way that the force of attraction between the magnetic elements when the receptacle is positioned on the holding device is greater than the gravitational force of the receptacle filled with liquid . At least one of the two magnetic elements can only be a magnetizable body that is attracted by an active magnetic element.

Due to the design with the magnetic elements, the receiving body can be attached to the holding device.

In particular, the holding device thus forms a hanging device that a person can hang around his neck, so that the liquid dispenser can be worn in front of the person's chest or stomach, like a chain pendant, in the attached state.

In an advantageous embodiment it is provided that the first magnetic element is fixed in relation to the receiving body. In particular, if the first magnetic element and the valve element are arranged at radially opposite positions of the receiving body, this configuration has the advantage of easy localization of the valve element when the liquid dispenser is arranged by means of the first magnetic element.

The localization can be assisted in that an area of the arrangement of the valve element has a different color than the area of the arrangement of the first magnetic element. For example, a ball-shaped liquid dispenser can have two differently colored ball halves. Due to the differently colored halves of the ball, it is very easy for a user to locate the side in which the valve element is arranged and in which the first magnetic element is arranged.

In particular, the first magnetic element can be fixed on the inside of the wall of the receiving body. Further possibilities for the arrangement of the first magnetic element are embedding in the wall of the receiving space, or also an arrangement on the outside of the wall, here possibly covered with a further layer of material.

In an alternative embodiment it is provided that the first magnetic element is arranged essentially freely movable in the cavity of the receiving body. Because of this, when an attractive force from the second magnetic element is active, the first magnetic element can automatically apply itself to a position on the inner wall of the cavity which is closest to the second magnetic element.

The advantage here is that no exact manual positioning is necessary in order to enable the magnetic fixation of the receiving body on the holding device.

In particular, the first magnetic element can have a spherical shape so that it can roll along the inside of the cavity and can correspondingly more easily position itself automatically.

The flow of the first magnetic element is only hindered to a small extent by the liquid. If necessary, a valve section protruding inwards prevents the first magnetic element from being positioned directly on the valve opening.

Another aspect of the present invention is an injection device for injecting a liquid into an object with a cavity, in particular into a liquid dispenser according to the invention. The injection device comprises a container for receiving the liquid and an injection unit for transferring the liquid into the object, the injection unit having a cannula for insertion into a valve element of the object which is complementary with regard to the cross section of the cannula. Furthermore, the injection device comprises a conduit element which is fluidically coupled to the cannula and which protrudes into the liquid when the container is at least partially filled with liquid or can be displaced at least so far with manual force application of the injection unit that after the cannula has been inserted into the object and a Pressure difference between the cavity of the object and the ambient pressure Liquid can flow from the container via the line element and the cannula into the cavity of the object.

In an advantageous embodiment it is provided that the injection device has a cover through which the injection unit passes.

In particular, the injection unit protrudes vertically from the cover.

In this case, the lid with the container can be essentially airtight, or alternatively, it can not be airtight.

In the case of an airtight seal between the lid and the container, the gas pressure in the object is increased if there is a fluidic connection between the interior of the object and the injection unit and a reduction in the volume of the interior of the object, e.g. by compressing the object. The injection device causes a corresponding gas flow through the injection unit and the liquid into the container, so that the pressure in the container is higher than the ambient pressure. During subsequent expansion of the object, if the object is still fluidically connected to the injection device, liquid flows from the container into the object due to the overpressure in the container.

In a further alternative embodiment, the container itself is deformable in such a way that when the interior of the object is connected to the injection unit and the volume of the interior of the object is reduced, e.g. by compressing the object and increasing the gas pressure in the object accordingly, the container volume is increased. Due to the elastic restoring forces of the container, it can deform back to its normal size and shape when the object is no longer compressed. A flow of liquid from the container into the receiving space is implemented accordingly.

The cannula does not necessarily have to have a pointed end area in order to be able to penetrate a tissue. However, a tapering in the end area is advantageous in order to be able to introduce it more easily into a valve in the object.

In the case of a non-airtight seal between the lid and the container, when the volume of the object is reduced and the object is subsequently expanded when the object is fluidically connected to the injection device, a negative pressure is generated in the object, so that the prevailing ambient pressure transfers the liquid from the container into the object lets flow.

The container can in particular have the shape of a pot, through the lid of which the injection unit extends upwards. The lid is advantageously removable or open for the purpose of refilling the container.

In addition, the invention provides a system for moistening, disinfecting and / or cleaning surfaces, which comprises a liquid dispenser according to the invention and an injection device according to the invention, with which a liquid for disinfection and / or cleaning through a valve element into the cavity of the receiving body of the Liquid dispenser can be injected.

In the embodiment with an extra valve element, this is clearly visible from the outside, so that it is possible for a user to insert the injection device into the valve element in a simple manner.

Insofar as the valve element is only designed as an incision, the receiving body can have at least one optically perceptible marking on its outside, which indicates to a user where a valve element is located, through which the liquid can be injected into the receiving body.

Another aspect of the present invention is a method for filling a liquid for moistening, disinfecting and / or cleaning into the cavity of the receiving body of the liquid dispenser according to the invention, in which the liquid is injected through a valve element into the cavity of the receiving body.

This filling can also take place through a relevant valve element or the opening formed or capable of being formed there if a baffle element or its anchoring part is inserted in the valve element.

In this case, the valve element has a double function, namely to allow the liquid to be let out and to be filled in.

the 1 and 2 each show a liquid dispenser 1 in different embodiments.

Both liquid dispensers 1 comprise a receiving body designed here in each case as a ball 10 through a wall 11 an inner cavity 12th limited.

In the cavity 12th is a liquid 40 , that is, a liquid that can be used to moisten surfaces, such as human skin, or to clean or disinfect the surface.

In a respective receiving body 10 or its wall 11 are several valve elements 20th integrated. It can be seen that these valve elements 20th in relatively high numbers evenly distributed through the wall 11 lead through.

The in 1 illustrated embodiment valve elements 20th on that as elongated incisions 22nd are trained.

In the 2 The illustrated embodiment shows valve elements 20th that appear as punctiform punctures 21 are executed.

In both in the 1 and 2 liquid dispensers shown 1 is each a first magnetic element 50 in receiving body 10 arranged.

3 and 4th each show a liquid dispenser with an apparent wall thickness of the wall 11 .

In 3 is the action of the first magnetic element 50 shown. A device according to the invention for moistening, disinfecting and / or cleaning surfaces here comprises a holding device 60 which in turn have a second magnetic element 61 includes, of which here in 3 only the south pole is shown. If the distance between the first magnetic element is sufficiently short 50 and the second magnetic element 61 these magnetic elements attract 50 , 61 to each other so that through the first magnetic element 50 also the wall 11 of the receiving body 10 against the holding device 60 is pressed. With a sufficiently strong force of attraction, the entire receiving body, even with a liquid filling, can thus be attached to the holding device 60 fix and from this the entire weight of the filled receiving body 10 take up.

3 shows an embodiment of the liquid dispenser according to the invention 1 , in which the valve elements 20th as relatively short cuts 22nd are executed. It can also be seen here that the through a valve element 20th developable opening at an angle 23 in relation to a radial extending from the center of the receiving body 10 runs radially, is aligned. This essentially serves to prevent the liquid from splashing out unhindered if the receiving body is squeezed 10 to avoid.

the 4th and 5 show the liquid dispenser 1 in a supplemented embodiment. How out 4th As can be seen, includes the liquid dispenser 1 several, through valve elements 20th or impact elements passed through their openings 30th . A respective impact element 30th includes an anchoring part 31 through the wall 11 of the receiving body 10 leads through. The impact element comprises on the outside of the receiving body 30th a baffle 33 that ensures that one out of the valve element in question 20th or its opening, leaking liquid 40 does not splash out unhindered, but first against the impact surface 33 meets and thus back onto the surface of the wall 11 is steered so that the receiving body 10 self-moistened.

To prevent a pressure increase in the cavity 12th the anchoring part 31 from the valve element 20th slips out, includes the anchoring part 31 on its the cavity 12th facing side at least one barb 32 .

5 shows one such with impact elements 30th provided embodiment in view from the outside, it can be seen that the baffles 33 relatively close to the wall 11 of the receiving body 10 are located, so that a total of essentially a spherical shape is retained.

the 6-8 show a further embodiment of a liquid dispenser according to the invention 1 . In the embodiment shown here, the liquid dispenser is 1 also executed in a ball shape. In contrast to the ones in the 1-5 However, the illustrated embodiments here include the liquid dispenser 1 just a valve element 20th . This valve element 20th is as a breakthrough in the wall 11 of the liquid dispenser 1 educated. It comprises a closure element 25th , which occurs when an injection element is passed through the valve element 20th can open, as well as when the pressure in the cavity increases 12th .

The closure element 25th can be from the wall 11 be designed, namely as a simple slot.

In an alternative embodiment, the closure element is 25th an element that stands out from the wall 11 differs, especially as an extra in the wall 11 integrated element.

In this embodiment, too, it is provided that in the liquid dispenser 1 or in its cavity 12th a first magnetic element 50 is arranged, here on a defined option, radially to the valve element 20th opposite. With this first magnetic element 50 can the liquid dispenser 1 be fixed or hung in the manner already described.

From the 6-8 it can also be seen that the valve element 20th has a substantially funnel-shaped inlet to facilitate the introduction of an injection element.

The one in the 6-8 The liquid dispenser shown is therefore particularly suitable for having an injection device 80 like them in the 9-11 is shown to cooperate.

The injection device 80 includes a container 81 , in its interior 83 the liquid 40 is recordable or recorded. The interior 83 the injection device 80 is up through a lid 82 closed. The lid 82 can be compared to the container 81 Be arranged in an airtight manner, or else air-permeable.

Through the lid 82 an injection unit leads through it 90 that are in the interior 83 with a conduit element 92 leads, the end of which is at least normal level of the container 81 with liquid 40 in the liquid 40 is located. This is achieved by adding a spacing 93 between the conduit element and the bottom of the container 81 is very low.

Above the lid 82 is one of the injection unit 90 included cannula 91 . This cannula 91 is fluidic with the line element 92 tied together.

1 0 shows a plan view of the injection device 80 . 11 shows a perspective view of the detection device 80 , here without liquid.

Will the cannula 91 through the valve element 20th of the liquid dispenser 1 pushed, there is a fluidic coupling of the cavity 12th of the liquid dispenser 1 with the liquid 40 in the container 81 the injection device.

When creating a negative pressure in the liquid dispenser 1 , such as after the liquid dispenser has been crushed 1 and subsequent expansion of the liquid dispenser 1 , becomes liquid 40 from the container 81 through the injection device 80 the liquid dispenser 1 fed. This sets a gas permeability of the container 81 , if necessary between container 81 and lid 82 , in advance.

Alternatively, you can also squeeze the liquid dispenser 1 Air from the cavity 12th of the liquid dispenser 1 via the injection device 80 in the interior 83 of the container 81 be guided so that in the interior 83 the gas pressure increases. The increased gas pressure then takes care of the subsequent expansion of the liquid dispenser 1 to that in turn Liquid 40 from the container 81 via the injection device 80 into the liquid dispenser 1 is pressed.

However, this implies that the container is airtight 81 or an airtight connection between the container 81 and lid 82 in advance.

Overall, the injection device 80 in a simple and uncomplicated way to the liquid dispenser 1 the required liquid 40 respectively.

12th shows a system according to the invention for humidifying, disinfecting and / or cleaning surfaces in a perspective view in the view from the side, 13th shows the system according to the invention for humidifying, disinfecting and / or cleaning surfaces in a view from the side, and 14th shows: the system according to the invention for moistening, disinfecting and / or cleaning surfaces in a view from above.

It can be seen that the injection device 80 with the liquid dispenser 1 are brought into a fixed mechanical operative connection, so that the liquid dispenser 1 or its receiving body 10 above the lid 82 the injection device 80 for the purpose of absorbing liquid from the container 81 is located. the 15th and 16 show the system according to the invention for moistening, disinfecting and / or cleaning surfaces in a side sectional view or in a perspective sectional view.

Here it can be clearly seen that the cannula 91 the injection unit 90 the injection device 80 through the valve element 20th and thus through the wall 11 of the receiving body 10 of the liquid dispenser 1 into the cavity 12th of the liquid dispenser 1 extends. Liquid can be drawn from the container accordingly in the manner described 81 via the injection unit 90 the cavity 12th of the liquid dispenser 1 are fed. After this filling process has been carried out, the liquid dispenser 1 simply from the cannula 91 be withdrawn, the valve element 20th of the liquid dispenser which closes 1 automatically and an unwanted leakage of the in the liquid dispenser 1 ingested liquids.
