Description

Field of application and state of the art

The invention relates to a discharge device for a medium having a housing, an outlet opening for the medium and a pumping device for conveying the medium from a medium reservoir to the outlet opening, wherein the pumping device has at least one movable first pump member which promotes relative movement relative to the housing causes the medium from the medium reservoir to the outlet opening.

Generic discharge devices are well known from the prior art. They are used in particular for the discharge of pharmaceutical and cosmetic liquids. These are usually conveyed by operating an actuating handle of the discharge by a user using the pumping device.

Also known from the prior art so-called deodorant scooters, on whose outlet side a ball is mounted, which is rotated by rolling on the skin of a user. It carries a film of liquid from an interior of the deodorant roller to the outside, where it is released by rolling on the skin of the user.

One problem with many dispensing devices of the prior art is that they ensure reliable media discharge only in certain orientations.

Task and solution

The object of the invention is to develop a generic discharge device to the effect that this allows a particularly comfortable and reliable way of discharging a medium on a surface, in particular on a skin area of a user.

According to the invention, this is achieved by providing at least one roll-off member rotatably mounted about a roll-off axis of rotation on the housing of a discharge device which is at least partially freely accessible on an outer side of the housing and which is coupled to the pumping device via a coupling mechanism. a rotational movement of the unrolling element causes a movement of the first pumping member and thereby a medium delivery by means of the pumping device.

A generic discharge device is preferably designed as a mobile device to be guided with one hand. This is intended with the at least one rolling member against a medium to be provided with the surface, in particular a skin area pressed. Starting from this pressed-starting position, the discharge is moved while maintaining a sufficient pressure force transversely to the extension of the Abrollglieddrehachse on said surface or skin area, wherein it comes to unroll the Abrollgliedes on the surface. As a result, the pumping device is actuated, which conveys the medium from the medium reservoir to the outlet opening, so that this medium is then released on said surface. The dispensing device according to the invention is particularly advantageous for the elderly and for people with physical disabilities, as it allows the medium to be deployed on any part of the body and without restriction as to the orientation of the dispensing device.

The outlet opening is preferably slightly set back from the maximum radius of the unwinding member, preferably by 2 mm or less, in particular between 1 mm and 2 mm. This ensures that even in an overhead position the medium reaches the area to be provided with the medium. This distance of 1 mm to 2 mm is particularly advantageous in connection with a wide outlet opening, preferably with a width of at least 15 mm, since it allows a strip of defined thickness and width to be applied to the skin which does not subsequent manual distribution by the user requires more. This is very useful, for example, in the application of cold wax.

The rolling member is preferably formed as a wheel. However, it can also be designed as a rotatable about the Abrollglied rotation axis ball. The Abrollglied-axis of rotation is preferably aligned orthogonal to the main direction of extension of the discharge and / or defined by the discharge opening discharge.

The unwinding member may itself be arranged in the outlet opening, so that the medium is dispensed via the unrolling member. However, a design is preferred in which the outlet opening is formed separately from the unrolling element and in which, in particular, different perforations are provided in a housing wall for the unrolling member on the one hand and the outlet opening on the other hand. The outlet opening may have different shapes and thus be designed, for example, to dispense the medium in the form of a broad bar.

As a medium storage known for discharge devices usual designs come into question. This is how a media storage can be designed be that it has a constant volume, wherein in the course of the discharge of the medium to prevent a negative pressure in the medium reservoir air is sucked to replace the discharged medium in the medium storage. However, preference is given to a volume-variable medium reservoir, in particular a medium reservoir such as a tube or a bag with a shape-flexible wall which adapts to the decreasing volume of media, or a medium reservoir with a drag piston. Such designs with volume-variable medium reservoirs are advantageous because they do not absorb air over their entire life cycle and thus there is no danger that the pumping device sucks air instead of the medium in unfavorable orientation of the discharge.

The pump device is designed such that it sucks the medium from the medium reservoir by means of negative pressure or sets the medium in the medium reservoir under overpressure, so that a medium discharge is ensured reliably and independently of the orientation of the discharge. The pumping device may be designed such that it directly encompasses the medium reservoir. In such an embodiment, the medium reservoir is thus reduced in volume in the course of rolling the Abrollgliedes to promote the medium to the outlet. However, a design is preferred in which the pump device is designed separately and is arranged between the medium reservoir on the one hand and the outlet opening on the other hand.

The pump device has, with the first pump member, at least one pump member, which is designed to be movable relative to the housing. Preferably, this movable pump member directly limits a volume variable pumping chamber of the pumping device. Alternatively, it indirectly conveys the medium, it being possible for example to design it as a sliding shoe of a peristaltic pump.

In a first embodiment, the first pump member is rotatably mounted relative to the housing. This allows a comparatively simple embodiment of the coupling mechanism. Particularly simple is the design, when the pump member is formed coaxially with the at least one Abrollglied and is firmly connected thereto. A greater structural flexibility is achieved when the rotatable first pump member is rotatably mounted about an axis deviating from the Abrollglied axis of rotation, which may for example be arranged parallel to the Abrollglied axis of rotation.

Such a rotatably mounted first pump member may be formed, for example, as a screw conveyor or in particular as part of a peristaltic pump whose delivery hose is squeezed together by means of the first pump member to push the medium in the hose in the direction of the outlet opening.

As an alternative to a first pump member rotatably mounted relative to the housing, the first pump member may in particular also be designed to be translationally movable relative to the housing and / or to a second pump member of the pump apparatus. This allows the design of the pump device as a piston pump, wherein the first pump member in such a case is preferably fixedly connected to the piston of this piston pump or forms. An embodiment of the pumping device as a bellows pump can also be realized by a first pumping element that is movable in translation.

A variant of this provides, the pump device with the first and the second pump member together as a whole about a first pivot axis pivotally mounted on the housing, wherein the first pump member is mounted on a abrollgliedseitig stationary and eccentric to the Abrollglied axis of rotation pivot axis pivotally mounted on the rolling member. With such a configuration, the pump device, which is preferably designed as a piston pump, is thus pivotally mounted in its entirety in the housing. The first pumping member and the second pumping member form the cylinder and the piston of the pumping device. Due to the pivotable connection of the first pumping member eccentrically on the rolling member is then simultaneously effected during the rolling of the Abrollgliedes a pendulum movement of the pumping device in its entirety and a lifting movement of the first pumping member relative to the second pumping member.

However, a variant in which the first pumping member is guided in a translationally movable manner along a housing-fixed movement path relative to the housing is advantageous.

The coupling mechanism between the unwinding member and the first pumping member can be achieved in such a case, for example via a pivotally mounted on the first pumping member and pivotally eccentrically mounted on the unwinding connecting rod intermediate member. However, a design is advantageous in which the first pumping member is operatively connected to the unwinding member by means of a slotted guide, this slotted guide preferably comprising a guide track rotatable about a guide track rotation axis and surrounding this guide track rotation axis on the unwinding member or a rotary member operatively connected to the unwinding member, which is spaced from the guide track rotation axis varying, and wherein the slotted guide further comprises an extension includes, which is attached to the first pump member and engages in the guide track.

As a result, a comparatively simple construction with few components is possible. In particular, this structure can be designed simply, if the guide track of the slide guide is provided directly on the rolling member, so that the guide track rotates together with the rolling member to the Abrollglied rotation axis. The extension, which is attached to the pump member and therefore only linearly movable relative to the housing, is translationally displaced by the varying spacing of the guide track of the guide track rotation axis and thus causes the pumping operation of the pumping device.

A coupling mechanism with slide guide forces both the stroke and the return stroke movement of the first pump member, so that a return spring, in particular a metallic return spring, can be dispensed with.

In the simplest case, the guide track, which is subject to varying degrees of deviation from the guide track rotational axis, can have an eccentric circular shape with respect to the guide track. Advantageous may also be more complex designs, in which the distance of the guide track from the guide track rotational axis has a plurality of minima and maxima, in particular two or three minima and maxima, since this can cause a 360 ° rotational movement of the guide track two, three or more pump strokes causes a piston pump.

Since, depending on the type of pumping device used, continuous delivery of the medium is not possible, for example because of the return stroke required for a piston pump, it may be advantageous to provide at least two pumping devices, wherein the at least one rolling-off element is coupled to the two pumping devices via the coupling mechanism that causes a rotational movement of the Abrollgliedes temporally staggered medium promotions through the pumping device. It is also possible for the pumping chamber of the pumping device to be followed by a homogenisation chamber which receives part of the medium, preferably 50%, of it during the pumping stroke of the pumping device and which discharges this stored medium through the outlet opening during the return stroke. Even so, a quasi-continuous promotion of the medium can be achieved.

The invention also relates to an attachment for use with a discharge device. The discharge device, for the use of which such an attachment is provided, comprises a housing, a medium reservoir, an outlet opening, a pumping device for conveying medium from the medium reservoir to the outlet opening and an actuating region movable in translation relative to the housing, by means of which the pumping device is actuated by translational displacement can.

The attachment according to the invention is designed such that it has a housing which is designed for releasable coupling to the housing of the discharge device. Furthermore, the article as well as the discharge device according to the invention described above, a rotatably mounted about an axis of rotation on the housing of the essay mounted rolling member, which is arranged at least partially freely accessible on an outer side of the housing of the essay. The attachment further has a translationally guided relative to the housing of the attachment movable actuating portion which is adapted to abut in a coupling state in which the attachment is coupled to the discharge device, on the actuating surface of the discharge device. In addition, a coupling mechanism is provided, which is coupled to the actuating portion and the rolling member, which causes a rotational movement of the rolling member a translational lifting movement of the actuating portion.

An inventive attachment works similar to the prescribed discharge device according to the invention. However, unlike the discharge device according to the invention, the attachment does not itself have a pumping device and a medium reservoir, but is instead designed to be placed on a discharge device known per se, which contains these components. The coupling mechanism is therefore not adapted to directly connect the rolling member with a part of the pumping device, but acts on the actuating portion, which in turn moves the pumping device of the coupled discharge and rests for this purpose, for example on an operating handle provided for manual operation of the discharge.

The attachment according to the invention can be used to easily modify conventional dispensing devices to dispense the medium stored in response to the unwinding of the unwinding member. The discharge devices used for this purpose can be used in a form suitable directly for manual discharge. However, it can also be provided that an applicator arranged on these discharge devices is removed before the attachment according to the invention can be coupled.

The housing of the attachment can preferably be attached to the housing of the discharge device by means of a connection that can be achieved without tools be connected, for example by a snap connection.

The essay can make do without its own outlet opening in a first embodiment. In such a case, the attachment is designed so that the outlet opening of the discharge, to which the attachment is intended coupled, even with attached attachment so exposed that the medium can be discharged directly through it. However, a design in which the attachment has a connecting channel which connects an outlet opening provided on the attachment with an inlet opening provided on the attachment is advantageous, wherein the inlet opening is arranged on the attachment in such a way that it is connected in the coupling state to the outlet opening of the discharge device.

Such a design may be advantageous because the attachment does not need recesses or the like to leave the discharge opening of the discharge device accessible. In addition, in many discharge devices, which are in principle suitable for use with the attachment, the outlet opening is displaced together with the actuating handle in the course of an actuation operation, so that without own outlet opening of the attachment a displacement of the outlet opening of the discharge relative to the attachment in the course of actuation would be expected. An outlet opening provided on the attachment also makes it possible to influence the discharge characteristics of the medium in a targeted manner through flow geometries assigned to the outlet opening.

Similar to the above-described discharge device according to the invention, it is considered advantageous if the coupling mechanism, which couples the roll-off member with the translationally movable operating portion, has a slotted guide. This preferably has about a guide track rotation axis rotatable and the guide track axis of rotation surrounding guide track on the rolling member itself or on a connected thereto rotary member, wherein the guide track is spaced from the guide track rotation axis varying. Furthermore, this link guide has an extension which is mounted in this case on the actuating portion and which engages in the guide track.

The mode of operation corresponds to the above-described mode of operation with regard to the discharge device according to the invention.

For easy handling of the dispensing device according to the invention or the article according to the invention, it is considered advantageous if two rolling elements rotatable about an identical rolling element rotation axis are provided, wherein the outlet opening of the discharge device or the attachment is arranged between the rolling elements. The use of two unwinding leads to increased stability and easier handling during use.

Furthermore, it is considered advantageous if a pressure-dependent opening outlet valve is provided in the region of the outlet opening of the discharge device or of the attachment in order to prevent the penetration of contaminants.

The at least one unwinding member is preferably designed as a massage roller with a plurality of protruding projections in the radial direction. With such a massage roller, a relaxing effect of the treated body part is achieved simultaneously with the discharge of medium. It is also advantageous if the at least one unwinding element is exchangeable without tools, so that the massaging effect can be selectively produced, adapted and avoided by changing the unwinding element.

The invention comprises, in addition to the discharge device according to the invention and the attachment according to the invention also a set of an attachment according to the invention and a known discharge with the above sub-components. In this case, the attachment is adapted to the discharge device, that the housing of the attachment to the housing of the discharge device can be coupled. In the coupled state that can be achieved thereby, the actuating portion of the attachment abuts against the actuating region of the discharge device.

In principle, a dispensing device according to the invention or a set with an attachment according to the invention can be used for a large number of liquid media. For example, use with food or glue is possible. However, use in particular with pharmaceutical or cosmetic products which are to be applied to the skin of a patient is regarded as intended use in particular. Accordingly, it is considered preferable if the discharge device according to the invention or the discharge device with the attachment according to the invention is filled with such a cosmetic or pharmaceutical liquid. As cosmetic fluids are especially nourishing cream, Cullulitecreme, sunscreen, body lotion, shower gel, self-tanner and cold wax dispenser for the depilation of body parts into consideration.

Detailed description of the embodiments

1 shows a discharge device according to the invention in an overall view.

This discharge device has a medium storage 10 to which an assembly 20 is coupled, which comprises in the manner explained below, the components for discharging the medium from the medium reservoir 10 required are. The assembly 20 has a housing, on whose front side an outlet opening 23 is intended for the medium. Both sides of the outlet opening 23 are in breakthroughs 21 of the housing rolling members 30 provided around a common axis of rotation 1 are rotatably mounted on the housing. In the manner explained below is a pumping device within the housing with the rolling members 30 operatively coupled such that rotation of the rolling members 30 around the unwinding member rotation axis 1 regardless of the orientation of the discharge device, a discharge of the medium through the outlet opening 23 through. To protect the discharge opening 23 when not in use is a flap 22 provided, which is mounted by means of a film hinge on the housing.

The illustrated dispensing device is provided for applying media to the skin of a user. It may be both cosmetic and pharmaceutical media. The discharge device is used with the flap open 22 with its top side pressed on the skin of the user and then in one of the arrows 2 clarified directions moved, in which case the rolling members 30 Roll on the skin of the user and thereby cause the discharge.

2 shows the assembly 20 and the media store 10 in an exploded view. The housing of the module 20 includes two housing components 24 . 26 by means of connecting means 25 be firmly connected with each other. The housing components define together 24 . 26 a recording room 27 in which the components described below are arranged.

This in the recording room 27 arranged components initially include the aforementioned rolling elements 30 , which by means of a shaft element 32 and a receiving bore 26a for the axle 32 on the upper housing component 26 are stored so that they pass through the openings 21 in the housing part 26 through to the outside for the intended use.

Furthermore, in the recording room 27 components 41 . 42 . 43 . 45 . 46 a pumping device 40 contained, the pump cylinder by a on the housing component 24 attached cylinder section 47 is formed. The components 41 . 42 . 43 form the piston of the pumping device 40 , The components 45 . 46 as well as the cylinder section 47 form the piston cylinder together with inlet valve.

The media store 10 is designed in two parts and has an inserted drag piston 12 ,

In composite form, the components in the 3 and 4 shown.

In these figures, the medium storage 10 shown in dashed lines. It can be seen that this is the drag piston 12 which is in the direction of the arrow 3 is upwardly displaceable. The area 14 above the tow piston 12 is filled with the medium to be discharged. In the course of sucking the medium through the pumping device 40 will the amount of media in the range 14 reduced, so that due to the tightness of this area against incoming air of the drag piston 12 in the direction of the arrow 3 moves upwards.

From the 3 is the piston of the pumping device 40 in the composite form. The component 41 is hollow cylindrical and has at its lower and at its upper end support areas 41b . 41c on, in hollow cylindrical areas of the housing components 24 . 26 along the pumping direction 4 are displaceable. In the hollow cylindrical component 41 is from below the trained as a piston core component 42 plugged in and locked, with the rest area 42a is formed in a manner not shown so that despite the inserted piston core 42 Medium in the hollow cylindrical component 41 can flow in.

On the piston core 42 is the piston cuff made of an elastic material 43 deferred to the composite from the piston core 42 and the component 41 is slidable to a limited extent to form an outlet valve on the outside is the piston sleeve 43 sealing on the inner wall of the cylinder portion 47 and limits a cylindrical pumping chamber 44 up.

A homogenization chamber 49 gets through the top end 41b and the outlet opening 23 limited. The purpose of this homogenization chamber is described below with reference to 5a to 5d still explained.

The lower end of the pumping device 40 is through an inlet opening 48 formed during a discharge of the valve ball 45 which is closed by an elastically deflectable arm of the in the lower end of the cylinder portion 47 pressed-in component 46 is pressed into its closed position.

On the hollow cylindrical component 41 are in the 2 well-visible extensions 41a intended. These extensions 41a stand out as in 4 represented, each in a guide track 30a the rolling elements 30 into it. How out 2 Obviously, these guide tracks surround 30a the Abrollglied rotation axis 1 the rolling elements 30 in non-constant distance. This leads to the fact that only together with the component 41 in pumping direction 4 translationally movable extensions 41a in the course of a rotary movement of the rolling members 30 alternately moved up and down. Together with the extensions 41a it will also be the entire piston 41 . 42 . 43 placed in a lifting movement and thus causes a discharge of the medium. This is based on the 5a to 5d explained in detail.

The 5a shows an initial state in which the piston 41 . 42 . 43 is in its upper end position, since the extensions 41a at that time in the part of the guide lane 30a engage, the Abrollglied rotation axis 1 is closest. Assuming that the pumping chamber 44 at this time already filled with medium, leads to a continued movement of the Abrollgliedes 30 in the clockwise direction, indicated by arrow 5 , to that the piston 41 . 42 . 43 in the direction of the arrow 4a is pressed down. Due to the valve ball pressed into the valve seat 45 can the medium from the pumping chamber 44 do not escape down. Instead, it comes to a forced due to the incompressibility of the liquid medium displacement of the piston seal 43 opposite the other piston components 41 . 42 , This creates a flow path between the piston core 42 and the piston cuff 43 opened and that in the course of the reduction of the pumping chamber 44 Pressurized medium may be along the arrow 6 at the piston core 42 passing in the configured as a hollow body component 41 inflow and by its connection to the outlet opening 23 be discharged through it. However, only a part of the medium is discharged because the homogenization chamber 49 at the same time due to the displacement of the component 41 undergoes an increase in volume down and therefore part of the through the pump 40 funded medium caches.

The continued movement of the unwinding member 30 clockwise also causes the continued discharge of the medium until the piston 41 . 42 . 43 has reached its lower limit position, in 5c is shown.

A starting from this continued movement of the Abrollgliedes 30 in the clockwise direction leads to a reversal of direction and a lifting of the piston 41 . 42 . 43 in the direction of the arrow 4b , Because the frictional forces between the piston sleeve 43 and the wall of the cylinder section 47 are larger than between the piston sleeve 43 and the other piston components 41 . 42 , the piston cuff shifts 43 in the course of this return stroke again towards the components 41 . 42 down and seals it with the 42b marked point with the piston core 42 so that during the return stroke no air through the outlet opening 23 through into the pumping chamber 44 can get. As a result, a negative pressure forms in the pumping chamber during the return stroke 44 that lifting the valve ball 45 from its valve seat and then a suction of medium from the area 14 of the media storage 10 into the pumping chamber 44 along the arrow 7 causes. This suction of the medium is over, as soon as the upper limit of the 5a was achieved. Once this is the case, the inlet valve closes again by turning the ball 45 is pressed back into its valve seat. Continued movement of the unwinding member 30 clockwise thus leads to a renewed discharge of the medium from the pumping chamber 44 ,

During the return stroke, ie when passing from the state of the 5c until the state of 5a , no medium from the pumping chamber 44 issued. However, in this phase, the component 41 displaced upward, causing a reduction in volume in the homogenization chamber 49 comes. This is the in this homogenization chamber 49 previously cached medium partially discharged. Thus, by the staggered volume reductions in the pumping chamber 44 and the homogenization chamber 49 ensures a largely continuous medium discharge.

The dispensing device shown, the application of pharmaceutical or cosmetic liquids on the skin of a user is very easy, since the user must carry the discharge only under slight contact pressure on the skin. This causes a pumping operation of the pumping device 40 , As the media storage 10 with a tow piston 12 is formed and thus always medium at the inlet 48 the pumping device 40 is present, it is also not to be feared that of the pumping device 40 only air is sucked in. It therefore does not depend on the correct orientation of the discharge when the medium.

The 6a and 6b show an alternative design. In this alternative design, there is a conventional discharge device 150 Application, which is an essay according to the invention 120 is supplemented.

The conventional discharge device 150 has a media storage 152 on. Furthermore, it comprises an internal and not shown pumping device. It has an operating area 154 with an outlet pipe 156 , The pumping device, not shown, can be actuated by this operating range 154 together with the outlet pipe 156 in the direction of the arrow 4a is pressed down.

This known per se discharge is around the essay 120 added. The essay 120 with two housing parts 124 . 126 is by means of a snap device 124a in a corresponding groove 158 the discharge device 150 snapped. The coupled state is in the 6b shown.

In this coupled state is sitting as a hollow body formed actuating portion 141 of the essay 120 on the operating area 154 the discharge device 150 and thereby includes its outlet pipe 156 ,

The operating section 141 is similar to the piston component 41 the embodiment of the 1 to 5 , In the same way as described there he has extensions 141 on that in a guide groove 130a two rolling members 130 of the essay 120 intervention. A rolling of the rolling members 130 about the Abrollglied axis of rotation 1 thus also leads to the essay 120 the embodiment of the 6a and 6b to a translational vertical displacement of the component 141 , Wherein, in the coupled state of the operating portion 154 as well as the outlet pipe 156 the discharge device 150 in a lifting movement in the direction of the arrow 4 be offset, which leads to a discharge process. That through the outlet pipe 156 thereby discharged medium penetrates at the lower end 141b in the hollow cylindrical component 142 and leaves this at the top 141c Then to the outlet opening 123 to be discharged.

The design of the 6a and 6b makes it possible to achieve the above-described advantageous Austragart also with conventional discharge devices, without having to be specially adapted for this purpose. You only need to have one option, the essay 120 to dock.

7 shows an assembly 220 , the alternative to the module 20 of the 1 to 5 Can be used. These are characterized by the fact that instead of the piston pump device 40 a hose pumping device 240 is used. This hose pumping device 240 has a pump wheel 241 on, around it a pump hose 244 which is an inlet 248 the hose pumping device 240 with an outlet opening 223 combines. On the pump wheel 241 opposite side is the pump hose 244 on a circular support surface 245 at.

The pump wheel 241 has axially on both sides two rolling members 230 on that with the pump wheel 241 are rotatably connected.

If these rolling members 230 in the manner described above, for example, rolling over on a skin area, the impeller rotates at the same time 241 with the same rotational speed. By outside extensions 242 to impeller 241 is the tube 244 by squeezing into individual chambers 244a . 244b divided, their content through the extensions 242 in the direction of the outlet opening 223 is pressed.

This design of the conveyor assembly 220 with a hose pump 240 allows a particularly simple and inexpensive construction of a discharge device according to the invention and an attachment according to the invention.
