Description

The invention relates to a dispenser for manually dispensing a mixture of at least two components. The dispenser comprises a delivery system designed for the simultaneous delivery of the at least two components and a housing into which at least two pressure vessels can be inserted, in each of which one of the components is under pressure.

Dispensers are known with which a substance can be dispensed by manual actuation of a delivery system, the substance being in a container under pressure. The substance is sprayed into the environment, in particular through a nozzle. This is the case, for example, with deodorants or room fragrances. Furthermore, dispensers for dispensing foams are known, as is the case with shower foams, for example.

However, users often want to put together a mixture of several substances individually in order to obtain a personalized product. This can be done, for example, by dispensing several substances from a respective donor, the substances then being mixed in the vicinity of the donors. However, a dispenser that can dispense several substances from the pressure containers inside would be more effective and simpler.

The object of the invention is therefore to provide a dispenser for the manually operated dispensing of a mixture of at least two components, with which several components can be dispensed simultaneously and in particular also in a simple and effective manner.

According to the invention, this object is achieved by a dispenser according to independent claim 1. Advantageous further developments of the donor result from subclaims 2-9. The object is also achieved by an associated dispenser-pressure container system according to claim 10 and a suitable pressure container according to claim 15.

It should be pointed out that the features listed individually in the claims can be combined with one another in any technically meaningful manner and show further refinements of the invention. The description additionally characterizes and specifies the invention, in particular in connection with the figures.

The dispenser according to the invention is used for the manual delivery of at least two components. The dispenser comprises a delivery system designed for the simultaneous delivery of the at least two components and a housing into which at least two pressure vessels can be inserted, in each of which one of the components is under pressure. The dispensing system has valve elements for gas-tight connection to a valve of each pressure vessel, and the dispensing system is designed to establish a conductive connection between this valve and a dispensing opening of the dispenser when a valve is connected to a valve element. This conductive connection is preferably designed to receive and guide solid, liquid or gaseous substances and can also be referred to as a fluid-conducting connection in the case of liquid and gaseous substances. The dispensing system also has a manually actuable trigger mechanism, which is designed to open and close the valves of the pressure vessels.

The valves of the pressure vessels can be male or female valves which are connected to and actuated by corresponding valve elements of the delivery system. In the case of a male valve, a pressure valve pin is preferably provided, which is received in a gas-tight manner by a valve receptacle of the delivery system. In the case of a female valve, however, the valve receives a valve element in a gas-tight manner.

The components to be dispensed can be the same type of substance or different types of substances that are mixed together. The dispenser according to the invention is preferably a hand-held device which can be used in particular in the fields of cosmetics, chemistry and medicine. With the device, at least two components or one or more substances can be mixed and applied or sprayed simultaneously in one operation. The handling is very intuitive and simple. The components / substances to be processed are located in exchangeable pressure vessels, which are also referred to as pressure cartridges. The device can accommodate several pressure vessels, the device being designed in particular to accommodate 2, 3, 4, 5 or more pressure vessels. In an embodiment in which the device is designed to use a plurality of pressure vessels, the device can also be operated with only one pressure vessel if required. The device is therefore designed in such a way that several pressure vessels do not necessarily have to be installed in order to be able to use it as a spraying device. It is also possible to use pressure vessels of different sizes. After they have been emptied, the pressure vessels can be removed from the dispenser and replaced with a new pressure vessel. The pressure vessels can also be exchanged for a newly desired mixture of substances.

The dispenser according to the invention therefore offers the advantage that different substances can be mixed or dispensed with it individually. The dispenser is very easy to use and pressure containers with substances can be exchanged flexibly. Since pressure vessels with appropriate valves are preferably self-closing, replacement is possible at any time. This means that even opened pressure vessels can be used repeatedly until they are completely empty.

In one embodiment of the invention, the dispensing system of the dispenser has means for guiding the pressure containers in the axial direction. In this way, the insertion of the pressure vessel in the desired position is facilitated. Such a targeted introduction is necessary so that the pressure vessel valves in a defined position lie, which enable the respective valve to be triggered by the delivery system. This is not necessary, for example, for dispensers with non-exchangeable pressure containers. The trigger mechanism and the delivery system are preferably designed to simultaneously open and close the valves of the pressure vessels. In this way, the substances can be released from the pressure containers in a particularly simple and effective manner.

Valve elements for receiving and triggering the pressure valve pins of the pressure vessels can be designed in various suitable ways. A vent receptacle is formed, for example, through an opening within a plate or another component. In particular, a valve element is formed by a tube. This allows a larger distance to be covered within the delivery system.

The connection between a valve element and a discharge opening can also be formed in various ways. For example, it is formed by a flexible hose and / or a flow channel within a rigid component. In one embodiment, the discharge opening is a nozzle opening of a nozzle element. In particular, this nozzle element is designed to be exchangeable. Depending on the needs of a dispenser, different types of nozzle elements can be used. For example, dispensing perfume or room spray requires a different nozzle element than dispensing foam.

The nozzle element is part of a nozzle head, which is preferably designed such that it is automatically aligned in a defined position when attached to the dispenser. This defined position means that a plurality of connections to a respective discharge opening are each aligned with a valve element in order to establish a conductive connection between the valve element and the discharge opening. This is necessary in order to engage the connection to a nozzle element with valve elements so that the function of the dispenser is ensured quickly and easily after the replacement of a nozzle head. This advantageously increases the variability of the dispenser according to the invention.

The discharge opening can be part of a nozzle element in which the components supplied from the pressure containers are mixed before they exit the nozzle element through one or more discharge openings. In this way, a mixing chamber can be implemented which can be used when the corresponding nozzle element is inserted or placed on.

The manually operated trigger mechanism actuates the valves of the pressure vessels for opening and closing in their longitudinal direction or at an angle to it. This is particularly the case with pressure valve pins. The trigger mechanism has spring means for supporting and / or resetting means for actuating the valves of the pressure vessels.

Furthermore, the manually actuable trigger mechanism has, for example, an actuating element which is movable transversely to the longitudinal direction of the valves of the pressure vessels, in particular at an angle of 90 ° to the longitudinal direction of the valves of the pressure vessels. The movement of this actuating element is deflected into a force with which the valves of the pressure vessels are actuated for opening and closing in their longitudinal direction or at an angle to it. For this purpose, the trigger mechanism has, for example, a lever mechanism or a mechanical gear for simultaneously actuating the valves of the pressure vessels. In particular, a wedge gear is used. In one embodiment of the invention, the trigger mechanism has a transmission plate which is pivotable about an axis and is designed to simultaneously actuate the valves of the pressure vessels.

In one embodiment of the invention, the dispensing system has at least one metering element for metering the flow from a valve element to a dispensing opening. In particular, a rotary wheel or a slide is used with which the cross section of a feed line can be varied. The mixture of several substances delivered by the donor can be further individualized.

The invention also includes a dispenser-pressure container system comprising a dispenser according to an embodiment of the invention and at least one pressure container in which a substance is accommodated under pressure. The pressure vessel is arranged in the housing and a valve of the pressure container is connected to a valve element of the dispenser. In particular, a pressure valve pin of a pressure container is received in a valve receptacle. In one embodiment of the invention, an outer contour is formed on the pressure container, via which the pressure container is guided in its longitudinal direction in the housing and / or the dispenser system. In this way, the required precise positioning of a pressure container in the housing of the dispenser is achieved. Coding of the dispenser to authorized pressure vessels can also be effected via this outer contour. This outer contour can be formed at various points on the pressure vessel. For example, it is formed on the body of the pressure container in which the substance is received under pressure. Alternatively or additionally, an outer contour can also be formed on a cap which covers the valve of a pressure container.

In one embodiment of the invention, the valve of the pressure vessel is covered with a cap which has an opening and a seal which covers the opening. A valve element of the dispenser is guided through the seal while breaking through the seal, the valve element being connected to the valve of the pressure vessel. For example, a valve seat is guided through the seal and holds the pressure valve pin of a pressure vessel. The cap for covering a valve of a pressure container thus remains on the pressure container when it is introduced into the dispenser. This simplifies the handling of the dispenser, but also enables additional functions of the cap. For example, it can have the described outer contour, which can be used for guiding and / or firmly positioning the cap within the dispenser. A positive fit of the outer contour of the cap in a receptacle of the dispenser with a corresponding inner geometry also enables the dispenser to be encoded on authorized pressure containers with the required caps.

In one embodiment of the invention, the cap also has a guide receptacle in which a valve element of the dispenser is guided in a form-fitting manner. This guide receptacle ensures a secure connection of a valve element with a valve of a pressure vessel. Furthermore, it can also take up leadership can be used for coding the dispenser on authorized pressure vessels. The inner contour of an opening in a cap and the outer contour of a valve element for the opening of the seal can also be geometrically matched to one another in such a way that the valve element is guided in the opening. This can also be used for an improved positioning of the pressure container in relation to the valve element of the dispenser. However, it can also be used as a further possibility for coding on authorized pressure vessels. The invention also includes a pressure container for use in a dispenser-pressure container system according to an embodiment of the invention. The pressure vessel is characterized in that it has a valve which is covered with a cap which has an opening and a seal which covers the opening. Such a pressure vessel has the advantage that its valve is protected by the cap against unintentional triggering. For use of the pressure container in a dispenser according to the invention, however, the cap does not have to be removed, but can remain on the pressure container. For the connection of the valve with a valve element of the dispenser, the seal is broken by the valve element. The cap can then be used to implement the described guiding, positioning and coding functions. For this purpose, in one embodiment of the invention, a described guide receptacle is formed inside the cap, which leads into the opening in the cap.

The figures show examples of embodiments of a dispenser according to the invention with three pressure vessels, but a number of two or even more than three pressure vessels is also possible. The dispenser delivery system is then adapted to the number of pressure vessels.

The basic structure and the mode of operation of the dispenser according to the invention will first be described with reference to the Fig. 1 explained. In principle, the dispenser 10 has a nozzle head 40 and a housing 20. The housing 20 forms the lower part of the dispenser 20 and a plurality of interchangeable pressure vessels are accommodated in the housing 20. The pressure vessels are preferably introduced into the housing 20 via the underside thereof, so that the housing 20 has a removable housing base 30 on its underside. The nozzle head 40 forms the upper part of the dispenser 10. It has a trigger mechanism that can be actuated by an actuating element 50. A dispensing system of the dispenser 10 is controlled via the trigger mechanism in such a way that when the actuating element 50 is actuated, substances are released from several pressure containers at the same time. They are fed to a nozzle element 41 via a connection system. The nozzle element 41 has one or more nozzle openings through which the substances are released to the environment. This nozzle element can optionally be designed with a mixing chamber in which the substances released from the pressure containers are mixed before they emerge from the nozzle element. Dispenser and pressure vessel together form a dispenser-pressure vessel system

The dispenser 10 is preferably made of plastic. However, it can also be formed from another material, such as a metal such as aluminum. The dispenser 10 has, for example, a symmetrical, triangular cross section with rounded corners. Furthermore, in an exemplary embodiment, the dispenser 10 is max. 350mm high and has a housing circumference of max. 300mm. It is designed so that it can be held well with one hand and by legal and Left-handed can be operated. At the upper end of the device is the nozzle head 40 and the trigger mechanism with the delivery system. The lower part of the device, the housing chamber 20, is hollow and can accommodate several pressure vessels.

Fig. 2 shows a possible embodiment of the nozzle head 40 in a detailed view. In one embodiment, the nozzle head 40 contains 1 to max. 15 individual nozzles. The nozzle shape and nozzle opening differ according to the substance to be processed. State-of-the-art nozzles for substances of all physical states can be installed.

In the interior of the nozzle head 40 there are, for example, permanently installed, short supply channels from the metering valve (= for example pressure valve pin) of a respective pressure container to the nozzles. Each inlet channel is optionally adjustable to regulate the flow rate. In one embodiment, this is done by changing the channel cross section, for example by means of a rotary wheel and / or a slide. In the embodiment of the Fig. 2 For example, three rotary wheels 70, 71 and 72 are provided on the top of the nozzle head 40. The flow rate can be regulated in a respective inlet channel by operating these rotary wheels. Such rotary wheels and / or slides can, however, also be provided at other suitable positions on the nozzle head 40.

The nozzles are arranged in a special position and angle depending on the content and application. The nozzle head 40 tightly encloses the individual pressure vessel valves (= for example pressure valve pins) or the feed lines to these. In one embodiment, the nozzle head 40 can be replaced without tools by snapping in and out. Another embodiment provides that a tool is required for attaching the nozzle head. For example, nozzle heads with differently configured nozzles can be used on a dispenser. In addition, individual nozzles can be removed from the nozzle head if necessary and new ones inserted.

In front of the outlet openings of the nozzles of the nozzle head 40, a mixing chamber with or without special tools can optionally be attached by clipping, screwing or pushing. In order to promote the mixing of the substances in the mixing chamber, there are fine profiles and / or structures in the interior of the mixing chamber, against which the substances are pushed past or through (static mixer or flow mixer). The mixing chamber can be removed, cleaned and reused or disposed of after use. Fig. 2 shows several built-in nozzles or nozzle elements 41 'and 41 ", which can have different types of mixing chambers.

A valve on a pressure vessel is a male or a female valve. In particular, it is a male valve with a pressure valve pin, but the invention can also be modified for female valves if a valve element in the delivery system is adapted accordingly. The valves of the pressure vessels in the housing 20 are opened by pressing or / and tilting. In order to trigger this and to reduce the force required for this purpose, a movable lever 50 is attached to the nozzle head 40. By pulling the lever 50 towards the housing 20, the valves of the pressure vessels open and close. The lever 50 is formed, for example, by a protruding plate or tab. However, it can also be another type of actuating element, such as a pressure plate, a push button or a slide. The associated mechanism of the actuating element can be constructed differently. For example, a trigger plate lowers or moves within the nozzle head 40 and at the same time opens the valves of the pressure vessels used. Metal or plastic springs can be attached in the push or pull direction so that the effort is additionally reduced. The lever mechanism is designed so that less effort is required than that for the direct triggering of all valves. The inlet channels run either under or over the release plate.

Fig. 3 shows an embodiment of a trigger mechanism in a schematic interior view. The trigger mechanism is housed in a nozzle head housing 48. The lever 50 merges into a pressure plate 52 which passes through an opening protrudes into the nozzle head housing 48. This pressure plate 52 is pivotally mounted on the nozzle head housing 48 via a first pivot axis 53, so that actuation of the lever 50 causes the pressure plate 52 to pivot about the pivot axis 53. Another transmission plate 62 is also mounted on the nozzle head housing 48 via a second pivot axis 61. This transfer plate 62 lies partially above the pressure plate 52, so that the two plates 52, 62 partially overlap. A pivoting of the pressure plate 52 thus causes the transfer plate 62 to be raised in the overlap region, which in turn causes the transfer plate 62 to pivot about the pivot axis 61, as a result of which the opposite region is lowered. As a result, a further pressure plate 60 is pressed down, ie in the direction of the pressure vessels which are located below the nozzle head. Through the pressure plate 60, the valves (= for example pressure valve pins) of all pressure vessels can be operated simultaneously.

The pressure plate 60 is optionally pressed down with the support of the spring force of several spring means 63, 64 and 65. As soon as the lever 50 is released, the pressure plate 60 lifts again, whereby the valves (= e.g. pressure valve pins) of all pressure vessels close again. This lifting of the pressure plate 60 can also be supported by spring means, which then serve as a restoring means (not shown).

For example, openings or receptacles (not shown) are formed in the pressure plate 60, into which pressure valve pins the pressure vessel is inserted from below. Starting from these pressure valve pins, there are feed lines to the nozzle element of the nozzle head. However, valve receptacles can also be formed on the underside of the pressure plate 60, in which pressure valve pins of the pressure vessel are accommodated. Furthermore, valve receptacles can also be formed which can be connected to female valves. In the case of a replaceable nozzle head, the dispenser and nozzle head are designed with guides in such a way that the valve elements on the nozzle head are positioned exactly without the need for complex adjustments so that they can interact with the valves of the pressure vessels.

The housing 20 can also be referred to as a housing chamber and is hollow. It holds one to n pressure vessels inside. The pressure vessels are pushed into the chamber with their valve (= pressure valve pin) in front and preferably snap slightly into the housing chamber. This can be done, for example, via its upper edge or other areas. This prevents the pressure vessels from accidentally falling out. The pressure vessels are, for example, longer than the housing chamber, so that they protrude from the bottom of the housing chamber and facilitate insertion or removal. For better handling, the housing optionally tapers at the transition to the nozzle head 40. The head part of the housing 20 accommodates the nozzle head 40. Fig. 4 shows the housing 20 without an inserted nozzle head.

Markings can be attached to the housing 20, which represent an important information and design element. The marking has in particular different colors, designs and optionally a corresponding label and identifies (in addition to the information on the pressure vessel) the content of a pressure vessel. E.g. If three pressure vessels are inserted in the device, three identification rings or stickers can be inserted. If rings are used, they are inserted, for example, via the housing 20 or between the base 30 and the housing chamber 20 and are clearly visible from all sides from the outside. In the case of stickers, they are simply attached to the device by pushing on, sliding on, adhesion or magnet.

In one embodiment, the underside of the dispenser 10 has a transparent recess or window opening in the floor through which the print cartridges are clearly visible from below. In the middle there is a button or rotary wheel, through which the housing base 30 is firmly connected / locked to the housing chamber 20 and also holds the inner pressure vessel (s) in position. Fig. 5 shows a housing base 30 with a grip element 31 in the form of a rotary wheel. The lock can be designed, for example, in the form of a bayonet lock or click / hook lock. The bottom 30 clicks slightly on the housing chamber 20 when closing. To prevent the floor from being opened accidentally and the If the pressure container could fall out, there is a slight resistance to overcome when locking and unlocking (engaging, disengaging).

Fig. 6 shows a further possible embodiment of a housing base 30 '. This housing base 30 'has a housing base body 32 with three side walls which are connected to one another via rounded edges. A floor surface is also provided, but in which three openings 33, 34 and 35 are formed. A star-shaped web 39 ′ is formed between these openings 33, 34, 35, in the center of which there is a centering pin 39. This centering pin 39 can be brought into engagement with a correspondingly shaped receptacle in the housing. Furthermore, a latching tab 36, 37 and 38 is formed at the ends of the star-shaped web 39 'in the region of the respective side walls, which projects above the respective side wall. Fig. 7 shows the housing base 30 'in a side view. A latching tab 36, 37, 38 has an outwardly facing latching lug, via which it can be latched with a corresponding structure within the housing 20. However, other types of latching elements can also be formed on such a latch.

For attaching the housing base 30 'to the underside of a housing of the dispenser, the housing base 30' is gripped by e.g. three fingers are pushed through the openings 33, 34, 35. The locking tabs 36, 37, 38 are pushed into the housing, being pushed slightly inwards until they can snap into receptacles in the housing. Through the openings 33, 34, 35, the bottom surfaces of the previously introduced pressure vessels can now be seen, these bottom surfaces preferably having markings so that it can be seen from the outside what type of pressure vessel is in use.

To release the housing base 30 'from the housing, three fingers are again pushed into the openings 33, 34, 35 in order to grip the star-shaped web 39'. The connection between the web 39 'and the locking tabs 36, 37, 38 is designed such that pulling on the web 39' in a direction away from the housing causes the locking tabs 36, 37, 38 to tilt in a direction away from the inside causes the housing, whereby the locking lugs of the locking tabs move radially inward. Thus, the latching tabs 36, 37, 38 can be pulled out of their receptacles in the housing by pulling the web, so that the housing base 30 'can be detached from the housing.

In an alternative embodiment, the receptacles for the locking lugs of the locking lugs 36, 37, 38 are accessible from the outside, so that the locking tabs can be pressed radially inwards to release them from the receptacles.

The pressure vessels used are preferably conventional pressure cartridges in the form of cans with a round cross section, as exemplified in the Figure 8B is shown. The pressure vessels have a max. Diameter from 20-100mm, in particular from about 30-40mm and a height of max. 50-300mm, especially about 150-200mm without valve. Fixed on the pressure vessel is a male valve that opens when pressed vertically and / or tilted horizontally and lets the contents flow out into the nozzle head 40 of the device. The valve is self-closing and tight when not operated.

The pressure vessels are preferably marked on the outside as well as on the floor according to their content. To protect the valve from accidental triggering and hygienic protection, a cap is placed over the valve. This cap can only cover the valve, as the embodiment of the Figure 8B provides. This cap 83 has a rectangular cross section. However, it can also be a larger cap with a different cross section, as is the case, for example, with the cap 82 with a round cross section Figure 8A the case is. In one embodiment of the invention, a cap is removed from a pressure container before it is placed in the dispenser housing. The cap then only serves to protect the pressure valve until the pressure container is introduced into the dispenser. In another embodiment of the invention, a cap remains on the pressure vessel when it is introduced into the housing. The cap can then be used in particular for guiding the pressure container in the housing. A defined positioning of the pressure vessel in an end position can also be achieved by the cap. For example, a receptacle can be formed within the dispenser in which a cap can be positively received. If you consider, for example the cap 83 with a rectangular cross-section, the pressure container can be positioned in a defined end position after the introduction so that the cap is received in a form-fitting manner in a receptacle with a rectangular inner contour.

In one embodiment of the invention, an opening is provided on the top of a cap 82, 83 which is covered with a seal. For example, the caps 82, 83 have a round seal 86, 87. Breakthrough and seal can be provided in particular if a cap remains on a pressure container when it is inserted into the dispenser. A valve receptacle for contacting the pressure valve pin of the pressure container sticks through the seal when the pressure container is inserted into the dispenser and receives the pressure valve pin inside the cap. The cap can have a guide receptacle in which the valve receptacle is guided in the longitudinal direction during this process. By means of a corresponding geometry of the valve seat and the guide seat, a form-fit seat can also be realized, which allows the valve seat to be inserted only in a certain radial position of the cap. A type of coding can also be implemented in this way to ensure that only authorized pressure vessels with a specific cap shape are used in the dispenser according to the invention.

Figure 9A shows a schematic section through a pressure vessel 80 with a pressure valve pin 84 and a cap 82, the components of the pressure vessel being shown in dashed lines. Figure 9B shows this pressure vessel 80 in a top view, a seal 86 also being shown in broken lines here. The cap 82 has an opening 88 on its upper side, which is provided with the seal 86 on the outside of the cap 82. A guide receptacle 89 opens into the opening 88 in the interior of the cap 82. The cap 82 covers the pressure valve pin 84 of the pressure vessel 80 and when the pressure vessel 80 is introduced into a dispenser, a valve receptacle 22 of the dispenser pushes through the seal 86. The valve receptacle 22 becomes guided through the guide receptacle 89 until it contacts the pressure valve pin 84 and receives it. The inner contour of the guide receptacle 89 has a hexagonal shape, for example. The outer contour of the valve receptacle 22 then preferably also has a hexagonal shape. In this way, the leadership 89 can also be used as a type of coding to ensure that only authorized pressure vessels with a specific cap shape are used in the dispenser according to the invention.

The Figures 10 and 11 show a further embodiment of a cap 82 with a specific outer contour. The cap 82 essentially has three side surfaces, into each of which a groove 130, 131, 132 is made. The cross section of these grooves 130, 131, 132 changes in the longitudinal direction of the cap 82. In particular, the cross section tapers in the direction of the opening of the cap 82, ie in the direction of the pressure vessel. This tapering can take place continuously and / or batchwise. When a pressure vessel with such a cap 82 is introduced into the dispenser, these grooves 130, 131, 132 can serve as a guide within a housing. A pin or web, for example, is then provided on the inside of the housing and is guided in a respective groove. The outer contour of the cap 82 can thus be used for an improved positioning of the pressure container within the dispenser.

An opening is provided on the top of the cap 82, which opening is covered with a seal 86. The breakthrough and the seal have a triangular shape. The seal 86 also forms a depression in the form of a funnel. This funnel shape can also be used for an improved positioning of the pressure container within the dispenser. When the dispenser is started up, the seal is broken by a valve element of the dispenser.

The outer contour of a valve element for the breakthrough of the seal and the inner contour of the breakthrough can be coordinated with one another, as a result of which the valve element is guided in the breakthrough.

The dispenser according to the invention can be used to process substances with different physical states that are located in the pressure containers that can be used. Possible substances (components) include: deodorant, room spray, perfume, skin care foam, gels, lotions, other foams, etc. Depending on the substance to be processed, the dispenser 10 becomes vertical (usually for spraying) with a nozzle head 40 applied upwards or nozzle head 40 horizontally or downwards (usually for gels, lotions, foams, etc.).

The handling of the dispenser 10 is described below. To insert a pressure vessel 80, the housing base 30 is unlocked and removed from the housing 20. Depending on the embodiment, a cap is removed from the valve of the pressure vessel or remains on it. The pressure vessel 80 is inserted with the valve first into the housing 20, e.g. until you feel it snap into place. The housing base 30 is reattached to the housing 20 and optionally locked by actuating the rotary wheel 31. To remove a pressure container, the dispenser is opened on the lower side as described and the relevant pressure cartridge is pulled out of the housing. This may take place against a slight resistance if a locking has to be overcome.

The Figures 12 to 27 show a further possible embodiment of a dispenser 10 according to the invention. The dispenser 10 has a housing 20 in which three pressure vessels can be accommodated, the section in FIG Fig. 12 shows two pressure vessels 80 and 81. The housing 20 can be closed on its underside with a housing base 30, which can be done by latching with several latches. The housing 20 forms the lower part of the dispenser 10 with the pressure containers 80, 81, while an upper housing part 29 comprises a delivery system 11. An intermediate frame 21 is located between this upper housing part 29 and the lower housing part 20. This intermediate frame 21 is clipped with openings in the lower housing part 20 via a plurality of unlocking pawls 25.

The delivery system 11 has a valve element in the form of a tubular valve receptacle 22, 23 for each pressure container 80, 81, which leads from the upper housing part 29 through the intermediate frame 21 to the pressure valve pins 84, 85 of the pressure container 80, 81. The pressure valve pins 84, 85 are received in the valve receptacles 22, 23. From the valve receptacles 22, 23 there is a connection to a nozzle element which, for example, in the Fig. 13 X is shown enlarged in a detailed view. This connection can be realized by hoses and / or channels in a rigid component. The flow through them is via dosing needles Adjustable feed lines, whereby in the Fig. 12 for example, a metering needle 73 is shown.

A nozzle element 41 can be designed in various ways with a plurality of nozzle openings and in particular with or without a mixing chamber. In the embodiment of the Fig. 13 a mixing chamber 47 is provided in a nozzle element 41. Flow channels open into the mixing chamber 47, of which the Fig. 13 two flow channels 92 and 93 are shown. A substance is fed to each of these flow channels 92, 93 via a hose 90, 91, which exits under pressure from one of the pressure vessels. The mixing chamber 47 with a central nozzle opening 44 for the exit of a substance mixture is formed in a nozzle insert 42. Fig. 14 schematically shows a section YY through the nozzle element, the various inlet openings of the flow channels 92, 93, 94 and the mixing chamber 47 being shown.

Fig. 15 shows a second embodiment of a nozzle element 41 'without a mixing chamber with a plurality of nozzle inserts 42, 43, each having a nozzle opening 44, 45. Each flow channel 92, 93 leads to a respective nozzle opening 44, 45. In this embodiment, the substances emerge separately from the nozzle element 41 '.

An actuating element 50 in the form of an actuating plate is attached to the upper housing part 29. The actuating plate 50 is actuated by pressure and cooperates with a pressure element 51, which transmits the force of the actuating plate 50 to a wedge gear. The force of the actuating plate 50 is deflected by the wedge gear in the direction of the pressure vessels 80, 81. For this purpose, a wedge presser 28 and a displaceable wedge slide 28 'are provided, the wedge surfaces of which can slide against one another. When actuating the actuating element 50 in the direction of the arrow, the wedge slide 28 'is pushed to the right by the pressure element 51. This takes place against the spring force of restoring means 24 in the form of springs. As a result, the wedge presser 28 is pressed in the direction of the valve receptacles 22, 23, as a result of which these are pressed onto the pressure valve pins 84, 85. Here, a valve piston is used, which is based on the Fig. 27 is described in more detail.

Fig. 16 shows a side view of a dispenser without lower housing part with pressure containers 80 and 81, which have different sizes. Also shown are a metering needle 73 for flow regulation and a further locking lug 12 for locking the intermediate frame 21 to the upper housing part 29. Fig. 17 shows such a dispenser with attached lower housing part 20, which is latched to the intermediate frame 21 via unlocking pawls 25. This locking can be released by pressing the unlocking pawls 25. Fig. 18 shows a front view of the dispenser with a view of a nozzle element 41 with a plurality of nozzle openings 44, 45, and 46, during Fig. 19 a rear view with two locking lugs 12, 13 and two unlocking pawls 25, 26 shows.

Fig. 20 shows a side view of a lower housing part 20 with a receptacle 27 for an unlocking pawl on the intermediate frame. Fig. 21 shows a top view of a dispenser when manually operated by two fingers. Fig. 22 shows the course of several cuts by a donor, which are explained below. Fig. 23 shows a section FF through a dispenser, based on which the pressure transmission between the wedge gear and the valve seats 22, 23 is explained. The wedge presser 28 presses via a hemisphere onto a valve piston 100, on which a valve seat 22 is formed. The valve piston 100 is received in a valve piston holder 115 and is movably mounted in the longitudinal direction of the valve receptacle 22. If the valve piston 100 moves in the direction of a pressure container 81, this takes place against the spring force of a compression spring 110 which surrounds the valve piston 100. The compression spring 110 is supported on the pressure piston holder 115. A snap ring 120 is also provided. If the pressure of the wedge depressor 28 decreases, the compression spring 110 presses the valve piston 100 back into its original position.

The Figures 24 a) to e) show the sections AA, DD, BB, EE and CC by a donor according to Fig. 22 . Fig. 25 shows in views a) to d) several views of an intermediate frame 21 with a plurality of unlocking pawls 25, 26 which are latched to the lower housing part. The upper part of the housing locks over several locking lugs 12.

Fig. 26 shows different views a) to d) of a wedge presser 28. The wedge presser 28 is formed by a plate, three hemispheres 102 being attached to one side of the plate. On the opposite side of the plate, three wedge elements 104 are formed which interact with wedge elements on the wedge slide 28 '. Fig. 27 shows various views a) to d) of a valve piston 100. A depression 101 is formed on the upper side of the valve piston 100 and serves as a receptacle for a hemisphere on a wedge presser 28. A bore 103 for receiving a metering needle is formed on one side of the valve piston. On the opposite side there is a channel 105, which serves to discharge a substance from the valve receptacle 22.
