Description

The Invention relates on the one hand to a device for dispensing flowable substances, especially pasty Products. On the other hand, the invention relates to a method for Donations of flowable substances, in particular of pasty products, in which the flowable substances by means of a donor nozzle from a storage chamber of a storage container out can get into the environment according to the generic term of claim 15. Above In addition, the invention relates to a method for producing a device for dispensing free-flowing substances, especially pasty Products, with a dispensing nozzle, at which the donor nozzle composed of several components.

Generic devices for dispensing free-flowing substances are widely known from the prior art. They are in various embodiments specifically used on mobile storage containers, within which stores products to be dispensed and / or dosed can be. Such products can For example, soaps, creams, shaving creams, and the like. Thus, the generic dispensing devices in everyday life Use often referred to as soap, cream or shaving cream dispenser. Such dispenser devices can but also to the issue of more liquid Products, such as disinfecting liquids.

often For example, such a dispensing device can be integrated in a cap of a storage container be so that they securely attached by means of the cap to the storage container can be. The dispenser device can in this case with an outlet valve of the storage container communicate such that with a manual operation of a pusher the Dispenser the outlet valve of the storage container to be opened can, creating a flowable substance conveyed out of a storage chamber of the container and over a dispensing nozzle the donor device can be donated to the environment. The advancement the flowable substance For example, by means of suitable pressure medium within the Storage chamber done. When the pusher is relieved again, the exhaust valve closes of the storage container and the promotion the flowable substance ends. Building such dispenser devices is relatively easy.

Furthermore There are more expensive to be built dispensing devices, which for example a additional delivery chamber include downstream of an outlet valve of a storage chamber and a dispensing opening a donor nozzle upstream. By means of dispenser devices designed in this way manages to flowable substances, which already in the delivery chamber are about to protect against oxidation with air, if the Dispenser is not used for the time being.

For example, from the European patent specification EP 1 399 370 B1 Such a last-mentioned dispensing device is known. In this case, a dispensing head of the dispensing device has a head piece and a dispensing piston, which can be referred to as a pump piston, for example. Both the head piece and the dispensing piston are arranged relatively displaceable relative to a storage container, so that, for example, a pasty product can be conveyed out of the container. Here, the addressed dispensing piston is arranged relatively displaceable relative to the head piece.

In The dispenser head becomes a delivery chamber formed, which usually in a container facing End area is provided. This delivery chamber can via a Valve or a valve disc are separated from the container interior, wherein this valve opens, when the pressure inside the container exceeds the pressure in the delivery chamber or exceeds a predetermined minimum amount.

Of the Dispenser piston is in such devices usually as Hollow piston formed and mounted longitudinally displaceable in the dispenser head. The dispenser head usually has such dispenser devices an output channel. Cooperating make the dispenser head and the dispenser piston often a slide valve. This is common designed so that the dispenser piston facing away from the bottom of the container End is closed on the front side and on one of this frontal End adjacent section has radial outlet openings. The output channel of the head piece ends doing so in the radial direction in the displacement of the dispenser piston.

Of the Dispenser piston is opposite the head piece relatively displaceable, so that it towards the container bottom can be moved so that an end facing away from the container bottom a fluid connection between the piston interior and the output channel of the head piece interrupts. With a suitable relative displacement of the dispenser piston relative to the headpiece in the direction of the container bottom opposite direction, or, in other words, during a movement of the dispenser piston with respect to the head piece up, the dispenser piston Occupy positions in which the radial outlet openings of the dispenser head can communicate with the output channel, so that a fluid connection between the output channel and the interior the dispenser piston is given.

As From the foregoing, the structure of such embodiments of dispenser devices quite complex. In particular, they have to each other relatively movable components and / or component groups with a Plural are sealed to accurate seals, otherwise can not be permanently and reliably ensured that a Dispenser valve reliable seals. For example, when filling the dispenser too much air is trapped, partly by donning normal pressing donor not possible. There is then a risk that only or mostly only compressed air and relaxed again, but no cream or no pasty Product promoted becomes.

It also goes, for example, from the document DE 195 31 341 A1 an integrally formed closure device forth. This closure device has a cover and a body, which are connected to one another in a material-locking manner. In a closed state, the lid and the body form a frictional connection. To release the non-positive connection another part is to be transferred to a latching position, whereby an edge is released on the lid in order to apply sufficient force in the direction of the opening direction on the lid by means of a finger. The body can be placed on a container attachment by means of an opening.

It Object of the invention, generic dispensing devices, a Method for dispensing flowable substances and a method of manufacturing a device for dispensing flowable substances continue to develop so that they work more reliably and at the same time are easier to produce.

The Object of the present invention is of a device for donating of flowable substances, especially pasty Products with a device for dispensing the flowable substances and solved with a shutter, in which the output device has an output channel with a discharge opening which can be closed with the diaphragm, and in which urforms the output device and the diaphragm together and positive fit are made.

Favorable Way can by means of the provided aperture an output channel of the present dispenser device structurally simply tapered or preferably even be closed, thereby reducing the risk can be that a flowable substance already in the dispenser, at a provisional disuse the dispenser device, dries out and the function of the dispenser device This is possibly adversely affected.

When Dispenser devices come here, for example, any devices into consideration, by means of which flowable substances controlled a suitable storage container can be discharged into the environment, so that they meet needs and donated well from the donor device can. The dispenser devices can this ideally arranged directly on a storage container be in which a larger amount a flowable substance is stored. You can do this the dispenser devices a housing By means of which they in a known manner at one end of the storage container can be attached to which of the storage container a suitable discharge opening comprising a dispensing valve. This case can also be used as a cap of the storage container serve. The dispenser device is preferred by a user manually operable, for example, by actuating a device, such as a pusher, by means of which the dispensing valve of the storage container can be opened.

Of the Term "flowable substances" almost includes all products which have a certain viscosity, ie flowable properties, inherent, allowing them to pass easily through a dispensing nozzle of the dispenser stream can. As already described, such products can be used about pasty Act products that should be delivered about dosed. Especially can in this case any fluids, such as gels, soaps, creams, but also foamed or foaming products be used.

Furthermore can also more fluid Be donated media by means of the present dispenser.

With the term "institution to spend ", below also called "output device" for short, In the present case, all devices of the dispenser device are used detected, by means of which flowable substances from a storage container can be donated to the environment.

Of the Term "aperture" describes In this case, any structure by means of which a cross section of an output channel an output device of the present dispenser device at least can be reduced. Preferably, the output channel is by means of the aperture completely airtight or at least fluid-tight sealable. The aperture can be within be arranged of the channel. The aperture is structurally simpler be realized at the dispenser device, when they outside of the Output device and outside radially in front of an exit opening of the output channel can be arranged.

Thereby, in that the dispensing device and the diaphragm are produced together in original form are, can They advantageously in a single joint step are produced, whereby the dispenser device according to the invention very economical can be provided.

Preferably act the output device and the aperture in this case together, that they share a donor nozzle the Can form a dispenser device, which is connected to an input side to a dispensing valve of a storage container which are a flowable substance through the dispenser device and which the flowable substance at a dispensing opening can deliver into the environment, the discharge opening is closed with the panel. Therefore, the dispenser device can be advantageously developed, when the shutter and the dispenser together form a dispensing nozzle of the dispenser form.

A preferred embodiment provides that the output device and the aperture of a at least two-component material are made together. For example, the output device made of a first plastic and the bezel is made of another plastic, so that the two components have different material properties can. This alone can be a donor nozzle of a generic dispensing device be advantageously developed further, so that this combination of features already without the rest Features of the invention is advantageous.

It It is understood that the output device and the aperture by means of a whole series of manufacturing methods are generated together can. For example, you can they are poured or extruded together. A particularly preferred variant provides that the dispensing device and the aperture in a common injection molding process are made. This allows both components manufactured with a single manufacturing step even when they are movably connected should. In addition, they are characterized by an injection molding process manufactured components or groups of components almost always by their high dimensional accuracy from and the components or component groups are very economical and in high volumes manufacturable.

Especially Against this background, the object of the invention of a Method for producing a device for dispensing flowable substances, in particular of pasty products, with a dispensing nozzle solved, at which the donor nozzle is composed of several components, and in which at least two Components of the dispensing nozzle in a common injection molding process be positively connected with each other in a single manufacturing step. For example, the output device and the aperture are called a component group with a first component and a second component injected together, wherein the first component relative to the second Component form-fitting fixed but movable.

Especially in injection molding you can make good use of that together with each other spraying materials during of curing faster or slower or stronger or shrink less. For example, the panel is injected from a first material, the stronger when solidifying can shrink as a second material in terms of the dispensing device, so that the aperture is particularly tight at the dispenser can be attached. In particular, this can be a good airtightness be created.

So an advantageous variant of the method also provides that one the plurality of components of the dispensing nozzle on another of the several Components of the dispensing nozzle is shrunk.

hereby can be a particularly intense positive connection between the Ensures components become. In this respect, it can be more advantageous in the case of the present dispenser device Way on additional Seals are dispensed with.

Become at least two of the plurality of components of the dispensing nozzle with each other connected by one of the components in or on another of the several components is injected, the components of the dispensing nozzle constructive simply synonymous insoluble be connected to each other.

Consequently can Components in particular the dispenser nozzle also captive to each other be attached when the output device and the diaphragm are insoluble with each other are connected.

It It is understood that the aperture relative to the output device or opposite the dispensing opening the output device in diverse Can be moved to the output channel or the output port partially or completely close to be able to. For example, the aperture at the output device by means of a sliding mechanism translationally displaced, or the output device is opposite the aperture shifted translationally.

Preferably, the output device is rotatably mounted on the aperture movable. The output direction can hereby rotate about one or be stored a plurality of axes of rotation on the panel, so that both components are structurally simple and very movable linked together. For example, one end of the dispensing device is cylindrical, wherein the longitudinal axis of such a cylinder can extend substantially transversely to the dispensing channel of the dispensing device. By means of the cylindrical shape, the output device can be pivotally mounted, for example, within a corresponding counter-structure on the panel.

Especially just can the output device and the diaphragm interact positively with each other be when the output device and the aperture by means of a Ball joints are connected together.

structural can be advantageous both components, ie output device and diaphragm, are designed, if the output device is a ball joint and the iris a Have socket. It is understood that the two components Alternatively, it can also be configured in reverse.

at such a ball joint is an end of the output device, for example as the aforementioned Joint ball formed. In the area of this joint ball, the Outlet channel out of the output device out, so that the discharge opening arranged in the sphere of the spherical surface is. Is the ball at least partially from the panel in Formed around the socket, the dispensing opening of the socket are either released or closed, depending on how the output device and the aperture to each other to be twisted.

includes the panel a means for stripping flowable substance in the area of the discharge opening the output channel, for example, a strand of flowable substance severed be as soon as about a pusher at the dispenser device is no longer actuated and a dispensing operation is ended. Preferably, the severing of the strand is involved a closure the dispensing opening through the aperture, so that the scraper constructive simply be built by means of the joint socket of the ball joint can.

insofar The object of the invention is also a method of donating of flowable substances, especially pasty Products, solved, in which the flowable substances by means of a dispensing nozzle from a storage chamber of a storage container out can get into the area where residues of flowable substances a donation at a dispensing opening an output device of the dispenser nozzle are stripped. According to the invention the dispensing device and a diaphragm produced by forming together and thereby positively connected with each other. Advantageously, an overhanging and / or supernatant Strand of flowable substances stripped from the dispenser when the shutter, for example Starting from a lateral area, pushed in front of the discharge opening becomes. This reduces the risk that such residues on the dispenser device remain at the end of a dispensing operation and dry can.

Become at the end of a dispensing scraping and / or closure means at a dispensing opening the output device moves past by the output device the donor nozzle and stripping and / or closing means of the dispensing nozzle against each other can be pivoted, on the one hand, the output device, in particular the above-described spherical surface, preferably residues on flowable substances be freed. On the other hand, the discharge opening structurally closed easily become. In the present case can the stripping and / or the closure means structurally easy with the aperture of the dispensing device can be realized and similar to the Joint socket of the ball joint described above with respect to the joint ball to be moved.

The Dispenser device can be further simplified structurally, if the panel or the dispenser comprises a cap of the dispenser. For example, the aperture and the cap in a common Spritzgießverfahrensschritt produced. Here you can the panel and the cap molded in one piece from an identical material so that making the dispenser device very easy can be held. This also applies if, alternatively, the output device and the cap in one piece are.

is the aperture on the cap of the dispenser device movable, preferably linearly movable, stored, the aperture can during a pivoting movement Present dispensing device at least partially a compensatory movement carry out, which reduces actuation forces on the pusher can be.

It will be understood that the aperture may be provided with one or more apertures through which flowable substances may pass when an aperture of the aperture is brought into registry with the dispensing aperture of the dispensing channel. For example, in order to rotate a joint ball of a ball joint within the socket only relatively slightly, to close about the discharge opening of the dispenser or open to can, provides a further advantageous embodiment, that the aperture is at least provided with an aperture. The aperture can in this case extend the output channel and provide at the end of a first cross-sectional enlargement, so that the flowable substances can already relax at the aperture. In this respect, the flowable substances can be provided very voluminous shortly after leaving the output channel.

The Aperture can cost in the area of an aperture with special material properties are fitted when the aperture a diaphragm region having an aperture, wherein the Aperture and the aperture area made of different materials are made. For example, a visor body is off a relatively ductile plastic made to work with the dispenser good seal, where sprayed against the aperture area of a harder plastic is to achieve good strength values. In particular, by a separate aperture area the dispenser nozzle versatile at its nozzle outlet or at the discharge opening the output device are designed.

The Dispenser device can be structurally further simplified if the output device means for actuating a dispensing valve of a storage container having. For example, the Means for actuating by means of a pusher be realized, which is provided at the output device, wherein the dispenser with a suitable receptacle on the dispensing valve is arranged. Will the pusher now manually operated, the dispenser can directly on the dispensing valve work it open will, and that flowable substance from the storage container can be introduced into the dispenser. Preferably are the means to operate and the dispenser of a single molded component, thereby further simplifying the construction of the dispenser device can.

The Output device can be particularly reliable with a relative communicate stiffly formed dispensing valve of a storage container, especially if there is a pusher on it to operate the dispensing device is provided when the output device an elastic receptacle for receiving a dispensing valve of a storage container has. For example, this can significantly improve the sealing effect between receiving the dispenser and the dispensing valve of the storage container be achieved. Preferably, the elastic receptacle is made a material which is softer than the material of the output device. Of the softer material of elastic absorption can also be in or be sprayed to the output device.

At This point should be noted that all features disclosed in the application documents individually or in combination mutually generic from the Prior art known dispenser advantageous develop further.

Further Advantages, objects and characteristics of the present invention explained with reference to the following description attached drawing in which exemplary dispensing devices for flowable substances with a dispensing nozzle and components the Spendervor direction thereof are shown. Components of the dispenser device, which in the figures at least substantially with respect to their Match function, can in this case be marked with the same reference numerals, these Components are not quantified and explained in all figures have to.

It shows:

1 schematically a sectional view of a first dispensing device with a dispensing nozzle for guiding a flowable substance in an unactuated position;

2 schematically another sectional view of the first dispensing device in an actuated position;

3 schematically a sectional view of another dispensing device with an elastic receiving device for a dispensing valve of a storage container; and

4 schematically a detailed view of a panel of an alternative dispenser device.

The in the 1 shown dispenser 1 for dispensing free-flowing substances 2 which are in a storage chamber 3 a storage container 4 are stored at an upper end 5 of the storage container 4 attached and there with a dispensing valve 6 the storage chamber 3 operatively connected.

The dispenser device 1 includes a cap in this embodiment 7 into which a dispensing nozzle 8th the dispenser device 1 is integrated. The donor nozzle 8th consists in the present embodiment of an output device 9 and a panel 10 so far the donor nozzle is 8th very simple. The cap 7 ensures a secure hold of the dispenser device 1 at the storage container 4 and is integral with the panel 10 formed, whereby the structure of the dispenser vorvor direction 1 is simplified.

Within the output device 9 On the one hand there is an output channel 11 in the area of the aperture 10 a dispensing opening 12 having.

On the side of the dispensing valve 6 has the output device 9 about a recording 13 into which the dispensing valve 6 can be plugged in, so that the output device 9 safe to operate with the dispensing valve 6 Can interact. The recording 13 is by means of a riser 14 spatially with the output channel 11 connected.

In the area of the dispensing opening 12 is the output device 9 with a joint ball 15 equipped with the ball joint 15 the output device 9 unsolvable in a joint socket 16 the aperture 10 is arranged. As a result, the two components output device 9 and aperture 10 the donor nozzle 8th by means of a ball joint 17 rotatably mounted to each other. In particular, the output device 9 at the aperture 10 rotatably movably mounted, as will be explained below.

The output device 9 and the aperture 10 are made of two different plastics, so that the dispenser nozzle 8th is made in the whole of a two-component material. Preferably, elastomers are used, so that the output device 9 and the aperture 10 can seal each other well. The output device 9 and the aperture 10 are manufactured together with an injection molding in a single process step, so that they are very simple and also very precisely designed.

It is particularly advantageous that the plastic of the panel 10 when curing can shrink more than the plastic of the output device 9 , This allows the socket 16 the aperture 10 the joint ball 15 the output device 9 particularly tightly enclosing, causing the output device 9 positive, thus very intimate and sealing with the panel 10 connected is.

As shown by the 1 is the dispenser device 1 in an unactuated position 18 , in which no flowable substances 2 via the dispensing valve 6 from the storage chamber 3 into the donor nozzle 8th arrives.

To the dispenser device 1 to press, must be present on a pusher 19 a suitable large actuation force 20 be applied, which causes the donor nozzle 8th on the storage container 4 can move. The pusher 19 can be provided in the present case with a soft-touch coating, so that a good feel can be created. By the load of the pusher 19 becomes the delivery valve 6 opened and the flowable substances 2 get into the channels 14 and 11 the donor nozzle 8th , When operating the dispenser device 1 In addition, the joint ball rotates 15 inside the socket 16 according to the direction of rotation 21 , wherein the discharge opening 12 of the output channel 11 with a shutter 22 is brought to cover (see 2 ), which in turn causes the flowable substances 2 passing through the dispensing nozzle 8th through, at the aperture 22 in the nearby areas 23 arrive and be available for actual use.

In the presentation of the 2 is the donor device 1 in an actuated position 24 shown in which flowable substances 2 from the dispensing nozzle 8th out in the area 23 can be donated. Will the pusher 19 however relieved again, the dispenser moves 9 opposite to the direction of rotation 21 , Here, the aperture shift 22 and the dispensing opening 12 opposite each other, reducing the aperture 10 the delivery opening 12 closes again. Advantageously, the aperture shears 10 in this return movement supernatants 2 from the surface of the joint ball 15 leaving residues of the flowable substances 2 from the dispenser 1 ideally completely removed. Thus, by means of the aperture 10 Advantageously here unspecified figured stripping and / or closure means are created.

As in the presentation of 2 Further, the compound is dispensing valve 6 and recording 13 relatively strong bent when the pusher 19 is fully activated. Although the output device 9 and therefore the recording 13 be made relatively soft by means of an elastomer, it is further advantageous if in the region of the dispensing valve 6 a particularly elastic recording 13 by means of a very soft material 25 is created (see 3 ). By means of the particularly elastic absorption 13 is also the tightness between the output device 9 and the dispensing valve 6 improved.

Regarding the detail view 30 ( 4 ) one recognizes particularly well, like the joint ball 15 the output device 9 in the socket 16 the aperture 10 rotatably mounted. To a shutter area 31 around the aperture 22 to be able to equip it with special features, is the aperture area 31 according to the detailed view 30 with another material 32 in the aperture 10 injected. This allows a variety of advantageous geometries with respect to the aperture 22 achieve.
