Description

The The present invention relates to cosmetic or dermatological Preparations made with the aid of trailing piston dispensing systems can be applied without would significantly change the cosmetic properties of these preparations.

donor with slidable trailing pistons (which are also used as trailing piston dispensers be designated) and manually operated Conveyors with a variable volume delivery chamber are as storage containers known in a variety of application examples, e.g. B. for personal care, in medicine for the application of medication or also in the provision pasty Food in stores. That is also correspondingly varied Design of for the provision of very different pasty masses donors used, especially in relation to their immediate conveying and handling mechanism.

such Dispenser systems are a matter of course principally for the application of cosmetic or dermatological preparations suitable. Those described in a special embodiment in WO-03/004374-A1 Trailing piston dispensers with a self-closing opening are special therefore advantageous for Use cosmetics because there are no product residues after application leak from the dispenser opening and therefore an unaesthetic one Contamination of the dispenser is avoided. On the other hand, the cosmetic or dermatological formulations when they emerge from the dispenser due to the special design (sealing lip on opening) subjected to strong shear, which causes a significant loss of viscosity of the cosmetic preparation. In connection with the loss of viscosity usually changes also the sensory properties of the preparation. The cosmetic preparations feel for example, less sensory (watery, empty) or unfavorably thin or convey a lower care character. However subject to the changes The properties of the product fluctuate considerably from Z. B. the strength and the speed of operation of the dispenser by the user as well as the temperature and the initial viscosity of the preparation. this leads to that the Product properties by the manufacturer only to a limited extent so influenced can be that the Users actually using the desired or a reproducible, about the entire duration of use and the same for all users if possible product quality receives.

task The present invention was therefore the disadvantages of the prior art to avoid technology and especially cosmetic or dermatological Find preparations that are made before and after application With the help of trailing piston dispenser systems, the same cosmetic as possible Have properties. In particular, preparations should be found which are the basis for Forms of preparation with diverse Can serve applications and yourself about it with very good sensory properties, such as the spreadability on the skin or the ability to draw into the skin Skin.

It was surprising and for the skilled person does not foresee that the use of at least 0.01 wt .-% of one or more hydrocolloids in cosmetic or dermatological preparations to prevent loss of structure the preparations when removed from donor systems in which the Preparations are exposed to shear when removed would remedy the disadvantages of the prior art.

preferred Dispenser systems in the sense of the present invention are drag piston dispensers, for example the trailing piston dispenser described in WO-03/004374-A1.

In a particularly preferred embodiment According to the present invention, the dispenser system is designed that the Conveyor one to the container and the headpiece longitudinally relocatable impeller comprises which one in the production chamber sliding piston with a sponsorship is connected, which is a delivery channel peripherally surrounds one with the delivery chamber communicating conveyor channel inlet opening and has a delivery channel outlet opening, by a displacement movement of the conveying element relative to the headpiece can be brought into a position in which the delivery channel outlet opening closes the output channel opens.

In the preferred dispenser, the delivery chamber opens to the delivery channel via a delivery channel outlet opening, which is released via a longitudinal displacement of the delivery element relative to the head piece. This relative movement is preferably achieved in that the head piece is operated manually, ie slid in the axial direction towards the container. The passage of the pasty product from the delivery chamber to the product delivery opening at the end of the delivery channel is accordingly already released by a translatory movement of the head piece relative to the delivery element. A previous build-up of pressure in the delivery chamber, as was required in the generic state of the art to release the passage, is not necessary. The actuation forces for dispensing pasty products from the dispenser are correspondingly reduced.

at the preferred donor is subordinate to the delivery chamber a conveyor channel provided by a funding body is surrounded. At the end of this channel it will be from the production chamber depleted pasty Product through the delivery channel outlet opening in output the output channel. Only after delivery of the product from the Delivery channel outlet opening is this in the output channel.

The the remaining output channel is in any case shorter than the usual one used donors. Accordingly, there is significantly less volume pasty Mass affected by possible oxidation processes. The remaining length of the Output channel can be particularly in those products that are against oxidation highly vulnerable are shortened be that the Output channel itself in extension the face of the head piece opens to the outside.

at an advantageous embodiment of the preferred donor the delivery channel outlet opening the peripheral surface of the funding body recessed and on the headpiece a the feed channel outlet opening in the starting position of the conveyor covering socket provided so that during a lifting movement of the head section for conveying out pasty Mass thereby a release of the delivery channel outlet opening shows that the delivery shaft is moved relative to the socket. This preferred embodiment is not only simple, but also allows an arrangement of the conveying channel outlet opening in in close proximity to the inlet opening of the Output channel for that to be funded Product.

With consideration for good axial guidance the conveyor relative to the headpiece is the aforementioned Socket preferably as a guide bush for the Conveyor formed and has at least one with the peripheral surface of the conveyor shaft interacting guide surface.

in the Terms of an inevitable Closure of the Delivery channel outlet opening at provision of the head piece according to a preferred development of the present invention proposed that at the headboard and the conveyor Driver means are provided through which the conveyor after manual operation when reset the headboard is taken to the starting position.

The aforementioned Driver means are preferably in a simple manner by a formed on the socket driver shoulder formed with a at the sponsorship molded driving ring cooperates. This takeaway wreath is preferably formed on the end of the conveyor shaft, so that the below of the driving ring recessed delivery channel outlet opening in the starting position by placing the driving ring on the walls of the headboard can be sealed.

at the aforementioned preferred embodiment can be that which is present in the output channel Volume can be further reduced in that the driver shoulder at the end at the socket and at the transition to the output channel and the driver rim in the front end area of the end-locked funding body is trained as this according to a preferred development of the present invention proposed becomes. In this preferred embodiment, it covers the ends the funding body arranged butt plate the delivery channel in the starting position the conveyor essentially flush and preferably has the driver rim.

According to one preferred development of the present invention takes place activity of the delivery piston preferably about the end faces the guide bush. In this preferred development, the delivery plunger protrudes the funding radial to form an annular contact surface for a printing surface, the at the end of the guide bush is formed and in the starting position with an axial distance to the contact surface arranged and by axially moving the head piece in Direction to the container to the contact surface can be created.

Also with a view to a simplification of construction, it is proposed according to a further preferred embodiment of the present invention to form the inner wall of the delivery chamber by an inner sleeve which is provided on the end face side of the container. Doing about the inner sleeve protrudes from the end of the container on the side facing the head piece. The inner sleeve is preferably integrally formed on the container in order to reduce the number of components.

to simple centering of the head piece during assembly of the dispenser and easy attachment of the head piece the container is according to one preferred development of the present invention proposed a head counterpart, the one pot-shaped to the aforementioned inner sleeve everted Holding cylinder and a concentric to the holding cylinder, the sliding displacement of the head piece leading guide cylinder having. The guide cylinder and / or the holding cylinder allow easy concentric alignment of the head part to the cylinder. Furthermore, the guide cylinder improves the leadership of the Lifting movement of the head piece when actuating of the donor.

at a further preferred embodiment of the preferred donor, where the conveyor chamber side End of the guide cylinder a delivery piston stop for the delivery piston trained, on the one hand, a relatively elongated guide for the delivery piston and on the other A stroke limitation of the delivery piston is provided in a simple manner. Such a stroke limitation lasts for example, the head part in the starting position firmly on the container, when the driver means are operatively connected.

Preferably the holding cylinder has a ring shoulder on the bottom, which a contact surface for a coil spring that trains the headpiece holds in the initial position under tension. This has the advantage that the outer peripheral surface of the Holding cylinder surrounds the coil spring on the inside and thus one Prevents the spring from buckling. The ring shoulder is preferred with this one Design placed on the front of the container and is thus particularly suitable, the head counterpart in the axial direction compared to the container set.

According to one a further, particularly preferred embodiment are the head counterpart and the head piece as prefabricated Dispenser component trained. Here are particularly preferred the headpiece and the head counterpart with their outer surface in each case Pot-shaped one above the other pushed, the head counterpart at least one stop to limit the axial displacement movement of the head piece relative to the head counterpart having. Located in the interior surrounded by the jacket surfaces in such an embodiment, preferably a reset element, for example the coil spring mentioned above, which the headpiece and the head counterpart spaced in the axial direction under pretension. The aforementioned Stop limits the axial displacement movement of the head piece, i. H. ensures after assembling the head piece and head counter piece Inclusion of the Pen for the cohesion of the two components that can be moved against each other. The dispenser component formed in this way can be different designed containers be put on what is an economical production of the donor for very different applications and container volumes allowed.

A particularly simple and durable connection between the prefabricated Dispenser component and the container is formed in that the Dispenser component with the container over at the Head counterpart and the front of the container trained locking means are locked.

Preferably in the preferred dispenser, the head piece is displaceable in length such that the head piece is by means of manual operation from the starting position first by a first axial distance to rest on the delivery piston with simultaneous exposure of the delivery duct outlet opening in the output channel can be brought into a central position and the head part thereafter with progressive axial displacement with entrainment of the delivery piston can be brought from the middle position into an output end position, in which the production chamber by moving the delivery piston has reached its smallest volume. In this preferred embodiment the delivery channel outlet opening and is exposed compressing the substance in the delivery channel as part of a rectified Movement of the head piece towards the container. This preferred embodiment allows a structurally simple solution of the preferred dispenser, in which the head piece directly on the delivery piston acts and this after exposure of the delivery channel outlet opening Promote pasty Crowd drives. This movement of the head piece usually takes place against the force of a biasing element, for example a spring, the one for that Take care that at a relief of the head piece this pushes away from the dispensing end position away from the container. at this movement, the axial distance a is first covered, d. H. the delivery channel outlet opening becomes closed again. With this closing movement there is a relative movement between the funding body and the output channel, where the volume of the output channel is enlarged at the inlet. As a result, the pasty mass located in the discharge channel withdrawn in the direction of the pumping chamber, ie from the product discharge opening of the Output channel removed in the header.

According to one a particularly preferred embodiment is located at this product delivery opening A sealing member. The closing part is preferably such that it is due to a pressure difference between the dispensing channel and the atmosphere for dispensing the pasty product. Will - as above mentioned - the pasty mass withdrawn in the dispensing channel away from the product dispensing opening, this results to a relative negative pressure in the output channel, which ensures that the closing part Product discharge opening seals particularly effectively.

in the With regard to one if possible good sealing it is preferable to close the product discharge opening to form a locking pin arranged in the discharge channel.

This closure Dorn is preferably in one piece molded on the headboard. The closure part, which is also ring-shaped, has one on the locking pin sealing lip that can be applied with an effective negative pressure closes the discharge channel effectively, but when the pasty product is being conveyed out releases a relatively large product delivery opening, through which the product is discharged with a relatively low pressure drop can.

Especially can be economically a closing part high effectiveness by means of two-component injection molding on the Shape the headboard as per one preferred development of the present invention proposed becomes. In this embodiment, the closing part is fixed to the head part connected. The closing part is preferably made of a soft elastic Plastic, particularly preferably made of a thermoplastic elastomer educated. It has been shown that in particular by a thermoplastic elastomer effectively seals the product discharge opening can be.

It has been shown that Material for the sealing part is particularly preferred for forming a functional surface on the frontal outer surface of the Headboard can be used. Such a functional surface can for example, a push-button surface that improves haptic properties, against which the user of the donor presses while using it. A such functional area is preferably through a coating at least on the outside of the headboard. The closing part and the cover are one piece molded, preferably by means of two-component injection molding the injection molding Manufacture of the headboard.

Further Details, advantages and features of the present invention will be apparent itself from the following description of an embodiment in connection with the drawing. In this show

1 a longitudinal sectional view of a first embodiment of a preferred dispenser;

2 a longitudinal sectional view of a second embodiment of a preferred dispenser.

This in 1 shown embodiment of a preferred dispenser has a container 1 , which is cup-shaped and on its underside with a base plate 2 which is connected to the container 1 is locked. The container faces on its other face 1 a top cover 10 on in the one container opening 11 is spared. This cover 10 is on the of the container 1 opposite side for receiving a dispenser head consisting of a head piece 3 , a head counterpart 4 and a pressure piston 5 educated. The dispenser also has one located above the cover 10 extending outer sleeve 12 of the container 1 pushed on cap 6 on. The container 1 , the bottom plate 2 , the head counterpart 4 as well as the pressure piston 5 are designed as rotationally symmetrical components and arranged concentrically to a central longitudinal axis X. Between the head piece 3 and the head counterpart 4 there is a schematically indicated coil spring 7 through which the headpiece 3 in the in 1 shown starting position opposite the head counterpart 4 is kept biased.

The headpiece 3 has a cylindrical outer jacket 30 on which radially inside immediately adjacent to the outer sleeve 12 of the container 1 and is arranged concentrically to this. The outer sleeve 12 of the container 1 dominates the container-side end of the outer jacket 30 in the axial direction. Accordingly, that appears in 1 shown embodiment of the dispenser even with the cap removed as a closed unit consisting of the container 1 and the headpiece 3 , As will be explained in more detail below, the head piece is 3 as well as the pressure piston 5 longitudinally displaceable relative to the container 1 held, the plunger 5 moreover, longitudinally displaceable relative to the head piece 3 is.

The cylindrical wall of the container 1 encloses an interior 10a for receiving the cosmetic or dermatological preparation in the sense of the present invention. In the container opening 11 extend star-shaped retaining webs 11a , On the the interior 10a opposite side of the cover 10 is concentric to the container opening 11 a cylindrical inner sleeve 13 arranged in the axial direction of the outer sleeve 12 is surmounted and the one funding chamber 100 surrounds. The inner wall of the inner sleeve 13 is smooth. The bottom of the production chamber 100 is through the cover 10 of the container 1 educated. The cover 10 has one in the delivery chamber 100 protruding ring wreath 15 on which the container opening 11 surrounds and between itself and the inner sleeve 13 an annular gap 16 forms.

The pressure piston 5 has an essentially cylindrical, internally hollow delivery shaft 50 on, at one end a delivery piston 51 is integrally formed. The delivery piston 51 towers above the funding body 50 radial and has upper and lower sealing lips on its outer peripheral surface 52 which the substantially ring-shaped delivery piston 51 protrude in the axial direction. On a sponsorship 50 facing the end forms the delivery piston 51 an annular contact surface.

The funding 50 has at one end one in the middle of the annular feed piston 51 recessed feed channel inlet opening 53 on. At the other end is the sponsorship 50 at the front through a butt plate 54 locked. The butt plate 54 covers a cylinder section 55 of the funding body 50 from the opposite shaft area 56 is enlarged in diameter. Between this shaft area 56 and the cylinder section 55 there is a driver rim that is inclined outwards 57 , Between the driving ring 57 and the butt plate 54 are on the outer peripheral surface of the cylinder portion 55 several delivery channel outlet openings 58 spread out. Between the delivery channel outlet openings 58 extend in the circumferential direction retaining webs, which the butt plate 54 wear. The feed channel inlet opening 53 communicates through one of the funding bodies 50 surrounding delivery channel 50a with the conveyor channel outlet openings 58 and forms a conveying passage for the pasty substance that is free of check valves.

The headpiece 3 has a cylindrical outer jacket 30 to which is concentrically an internally hollow guide bush 31 is arranged with an output channel 32 communicated. The front end of the guide bush 32 forms an end face printing surface 33 which in the axial direction from the outer jacket 30 is towered over. The guide bush 31 points adjacent to the front printing surface 33 a first bushing section which has a smaller inner diameter than the second bushing section lying behind in the conveying direction of the pasty substance. There is a driver shoulder between the first and the second bushing section 34 formed, which connects the two sections of different bushing diameters with one another via a slope. The second bushing section opens into an output channel that extends laterally from the central longitudinal axis X. 32 ,

The head piece points approximately at right angles to the central longitudinal axis X. 3 on ribs 36 trained spring contact surfaces 37 on. Ribs 36 extend approximately in a star shape from the socket 31 to the inner surface of the outer jacket 30 , Accordingly, between the inner surface of the outer shell 30 , the outer surface of the guide bush 31 and the spring contact surfaces 37 one to the bottom of the head piece 3 open annulus 38 educated.

The headboard 3 is to the container side of the outer jacket 30 open and formed above this end face essentially in the manner of a cap. On the front of the outer jacket 30 opposite top of the headboard 3 there is a product delivery opening 39 of the output channel 32 ,

The head counterpart 4 has essentially two concentric cylinder sections, namely an outer holding cylinder 41 and a smaller diameter guide cylinder 42 , The holding cylinder 41 towers over the guide cylinder 42 on the the container 1 facing side, whereas the guide cylinder 42 the holding cylinder 41 towered on the other side. On the the container 1 facing end of the holding cylinder 41 a radially inwardly extending annular web is provided, which is approximately centered on the outer surface of the guide cylinder 42 encounters.

The holding cylinder 41 has an outwardly projecting circumferential ring shoulder on its container-side end. The front side of the guide cylinder on the container side 42 forms a delivery piston stroke.

The delivery piston is in the assembled state 51 of the pressure piston 5 slidably in the inner sleeve 13 of the container 1 and thus covers the end of the delivery chamber 100 from. The head counterpart 4 is concentric with the inner sleeve 13 arranged and with its holding cylinder 41 pot-shaped over the inner sleeve 13 pushed. The ring shoulder of the head counterpart 4 is due to the container 1 abgewand end of the cover 10 on.

The ring shoulder of the head counterpart 4 is located approximately in the area of the front end of the inner sleeve 13 , The guide cylinder adjoining this radially inwards 42 surrounds the end of the guide bush 31 of the headboard 3 , Radially inside this guide bush 31 is the funding body 50 with its shaft area 56 smaller diameter. The delivery piston 51 of the pressure piston 5 is slidable on the inner wall of the inner sleeve 13 arranged. The ring-shaped contact surface of the delivery piston 51 is located on the end of the delivery piston stop of the guide cylinder 42 on. This will make the spring 7 on the headpiece 3 Exercised preload, which is maintained by the attachment of the driver shoulder 34 and carrier ring 57 the pressure piston 5 in a direction away from the container 1 biases.

Between the delivery chamber 100 and the interior 12 of the container 1 there is a container valve designed in a known manner 20 that with its sealing washer 21 against the ring wreath 15 the cover 10 fits and the interior 10a opposite the production chamber 100 seals.

in the the dispenser is in the starting position (0).

When using the dispenser, a user presses the headpiece 3 towards the container 1 , Due to the incompressibility of the in the delivery chamber 100 and the delivery channel 50a the pressure piston remains 5 in its position. The headpiece 3 moves relative to the plunger 5 towards the container 1 to. The form-fitting system between the driving ring 57 and the takeaway shoulder 34 is loosened until the butt plate 54 against the inner surface of the socket head 35 bumps or - depending on the design - the front pressure surface 33 at the end of the guide bush 31 on the annular contact surface 51a of the delivery piston 51 comes to the plant (middle position M). After this axial displacement by the displacement path a, the delivery duct outlet openings are located 53 in the output channel 32 free.

The headpiece 3 is in this as well as in any other axial relative movement between the head piece 3 and the head counterpart 4 or between the head piece 3 and the container 1 by creating the outer peripheral surface of the guide bush 31 on the inner peripheral surface of the guide cylinder 42 slidably guided. The relative movement between the head piece 3 and the pressure piston 5 over the contact of the peripheral surface of the second shaft section with the shaft region 56 guided.

With progressive pressure movement of the head piece 3 towards the container 1 becomes the pressure piston 5 taken. This reduces the volume of the delivery chamber 100 , so that it is in the conveying direction behind the container valve 30 pasty product located via the conveyor channel outlet opening 53 into the output channel 32 is delivered. The pasty product leaves the discharge channel via its product discharge opening 39 ,

At the end of this relative movement of the head piece 3 towards the container 1 butt the sealing lips on the container side 52 of the pressure piston 5 against the face of the ring gap 16 , In this final delivery position V the delivery chamber has 100 reaches its smallest volume.

Now becomes the headpiece 3 released by the user, so the coil spring presses 7 the headpiece 3 back in the opposite direction. The pressure piston initially remains here 5 in its final output position V. Only the headpiece 3 moves away from the container 1 until the driver shoulder 34 for attachment to the driving ring 57 comes.

With this axial displacement by the distance a, this becomes in the output channel 32 pasty product in the space formed between the butt plate 54 and the inside of the socket head 35 withdrawn. The pasty product then no longer lies directly at the product discharge opening at the end of this displacement movement 39 of the output channel 32 on, which prevents pasty product from the discharge channel at the end of the conveying process 32 drips or due to contamination in the area of the product discharge opening 39 is affected.

After the relocation by distance a and the creation of the driving ring 57 and driving shoulder 34 also becomes the pressure piston 5 as the headpiece moves 3 moved back to the starting position, which is achieved when the delivery piston stop against the annular contact surface of the delivery piston 51 is applied. With the relative movement of the pressure piston 5 away from the container 1 becomes a pasty product from the interior 10a of the container 1 through the container opening 11 into the delivery chamber 100 promoted. The one in the interior 10a the resulting negative vacuum leads to known way to a wake movement in the interior 12 trailing piston located 22 ,

In 2 a second embodiment of a preferred dispenser is shown.

In this exemplary embodiment, the same parts are identified with the same reference symbols as those previously discussed. The container 1 of in 7 The embodiment shown is essentially identical to the container described above, with an outer container wall that has an interior 10a surrounds in which a trailing piston 22 is arranged longitudinally displaceable and which of a base plate 2 is closed. In contrast to the previously described embodiment, the container has 1 a circumferential locking ring on its front cover 17 on. The head counterpart 4 is over the ring shoulder 44 extended radially outward and has a substantially parallel to the holding cylinder 51 extending cylindrical outer wall 46 whose diameter is larger than the diameter of the outer jacket 30 of the head piece 3 is. Between the outer wall 46 and the holding cylinder 41 is on the underside of the head counterpart 4 a recess 47 molded which with the locking ring 17 to form a snap connection between the head piece 4 and the container 1 interacts.

At the in 2 The embodiment shown is the head counterpart 4 together with the head piece 3 designed as a prefabricated dispenser component. That the container 1 away free end of the outer wall 46 of the head counterpart 4 is radial to the formation of a locking lug 46a bent inwards and protrudes in the axial direction of a ring bead 30a that is on the outside of the outer jacket 30 on the headpiece 3 is provided. This forms a stop through which the head counterpart 4 captive with the headpiece 3 connected is. This stop keeps the spring 7 applied spring forces. The the headpiece 3 and the head counterpart 4 comprehensive dispenser component can thus be mounted on the container before assembly 1 be pre-assembled. For this the spring 7 into the cavity between the head piece 3 and the head counterpart 4 used. The two components 3 . 4 are pushed into each other in the axial direction until the ring bead 30a at the inwardly bent end of the outer wall 46 slipped by.

At the in 2 shown embodiment has the pressure piston 5 a carrier wreath 57 on the one on the butt plate 54 is formed. The drive ring seals accordingly 57 at the in 2 shown starting position the output channel 32 from. The funding 50 has a shaft area 56 with a reduced diameter, the longitudinal extent of which corresponds to the axial distance a. Accordingly, the axial displaceability of the pressure piston 5 opposite the headboard 3 through the butt plate 54 on the one hand and the longitudinal extent of the shaft area 56 with a reduced diameter on the other hand.

At the in 2 shown embodiment compared to the aforementioned first embodiment, the further difference that in the output channel 32 a locking pin 32a is provided, which is in one piece on the head piece 3 is formed. Through the locking pin 32a becomes the product delivery opening 39 annular. The product delivery opening 39 is in the embodiment shown by an annular closing part 60 covered, which as a separate component made of a thermoplastic elastomer with the head piece 3 connected is. The closing part 60 lies in the in 7 Starting position on the outer peripheral surface and on parts of the end face, but in particular the peripheral surface of the locking pin 32a and thus seals the output channel 32 from. In one piece with the closing part 60 is a coating 61 , the same material as the closing part 60 is formed and which over a major part of the front cover of the head piece 3 extends. Through this coating 61 becomes a non-slip functional surface on the head piece 3 educated.

When pressing the in 2 donors shown run the above in particular with reference to the 1 explained processes. However, there is the difference here compared to the aforementioned embodiment that when resetting pressure pistons 5 and headpiece 3 the output channel is sealed from the environment. With a relative movement of the pressure piston 5 relative to the headpiece 3 towards the container 1 too, that will be in the output channel 32 located product - as already mentioned before - against the conveying direction back into the interior of the head piece 3 drawn. At the in 2 illustrated embodiment causes the resulting pressure gradient between the atmosphere and the output channel 32 a completely sealing contact of the closing part 60 on the surfaces of the locking pin 32a , Accordingly remains in the output channel 32 adjacent pasty product almost unaffected by any oxidation processes. The butt plate also seals 54 the conveyor channel 50a towards the output channel 32 from, so that in particular an impairment in the delivery channel 50a pasty product through possibly in the output channel 32 penetrating air is avoided in any case.

The two exemplary embodiments described above together have the advantage that the feed channel openings 58 only after a relative movement between the headboard 3 and the pressure piston 5 in the output channel 32 exposed. For conveying the pasty product from the delivery chamber towards the product discharge opening 32a it is not necessary that the internal pressure initially built up in the delivery chamber 100 is used to open a check valve located behind in the conveying direction. Accordingly, the pasty product can be removed with less effort. Furthermore, both of the above-mentioned exemplary embodiments offer the advantage that the pasty product against the conveying direction after the head piece has been actuated in the dispensing channel 32 withdrawn, the in 2 The embodiment shown has the permitted advantage that the sealing part of the closing part 60 on the locking pin 32a the pasty product contained in the dispenser is reliably protected against impairment, for example by oxygen in the air.

• (Al _m Si ^{2 -} _m O ₅ ( ^{2 + m} ) ^- ) for aluminosilicates.
• m is a number greater than Zero and less than 2.

If there are no pure silicates but aluminum silicates, one has to take into account the fact that every Si ⁴⁺ group replaced by Al ³⁺ needs a further simply charged cation for charge neutralization changed.

The charge balance is preferably balanced by H ⁺ , alkali or alkaline earth metal ions. Aluminum as a counter ion is also known and advantageous. In contrast to aluminum silicates, these compounds are called aluminum silicates. "Aluminum aluminosilicates" in which aluminum is present both in the silicate network and as a counter ion are also known and may be advantageous for the present invention.

The preparations according to the present invention can also advantageously contain surfactants ten, especially if they are in the form of foaming surfactant preparations.

surfactants are amphiphilic substances, the organic, non-polar substances in water to be able to solve. You worry due to their specific molecular structure with at least one hydrophilic and a hydrophobic part of the molecule, for a reduction of the surface tension of water, wetting the skin, facilitating dirt removal and solution, a gentle rinse and - depending on your needs - for foam regulation.

The hydrophilic parts of a surfactant molecule are mostly polar functional groups, for example -COO‾, -OSO ₃ ^2– , -OSO ₃ ‾, while the hydrophobic parts generally represent non-polar hydrocarbon radicals. Surfactants are generally classified according to the type and charge of the hydrophilic part of the molecule. There are four groups:

• - anionic surfactants,
• - cationic surfactants,
• - amphoteric Surfactants and
• - non-ionic Surfactants.

anionic As functional groups, surfactants generally have carboxylate, Sulfate or sulfonate groups. In aqueous solution they form in acid or neutral environment negatively charged organic ions. cationic Surfactants are almost exclusive characterized by the presence of a quaternary ammonium group. Form in aqueous solution they are positively charged organic in an acidic or neutral environment Ions. Amphoteric surfactants contain both anionic and cationic Groups and behave accordingly in aqueous solution depending on the pH value like anionic or cationic surfactants. They have one in a strongly acidic environment positive and in the alkaline environment a negative charge. In neutral In contrast, the pH range is zwitterionic, as in the following example should clarify:
