Description

The invention relates to a dispenser with the preamble features of claim 1.

Such a donor is from the document US4993594 A known. Substances such as cosmetics, hair dyes but also adhesives or other chemicals are stored in vessels that are equipped with a dispensing device such. B. from the DE 692 08 264 in the form of a squeeze bottle with a disposable bag therein. These so-called donors allow the removal of a defined amount of the substance and at the same time prevent air from entering the containers. In addition, these dispensers make it possible to remove the substances without having to open screw caps or the like. A disadvantage of conventional dispensers that they usually have a pumping mechanism that outputs the substances from the (single) container on the dispenser, so that the construction cost is relatively high, especially for cosmetics or hair care products increasingly two-component dispenser are required.

In addition to the known dispensers, tubes or bottles are also used for the storage of the above substances, which have dosing heads or metering, from which the substance exits after direct pressurization of the container. A disadvantage of these vessels is that there is no complete emptying of the substance from the container, so residual amounts of the often expensive substances remain. In addition, air can enter the interior of the container via the discharge opening, which can lead to oxidation or spoilage of the substance. In order to address the latter problem and to prevent air from entering the substance-containing container, so-called "bag-in-bottle" or "bag-in-bag" packages are proposed. These comprise an outer container, for example a plastic bottle made of a relatively solid material or a tube, in which a second container filled with the substance, usually a blown bag, is arranged. Such dispensers are frequently used in pharmacy for aerosols and produced in the so-called coextrusion process. Between the outer vessel and the bag enclosed thereby, a gap is provided which is filled with air. When the outer packaging is pressurized, it is compressed and passes the pressure to the bag via the air present in the intermediate space. For this then exits the substance via a corresponding dispensing valve. In this case, air can flow in order to replace the extracted substance volume.

A disadvantage of the mentioned packaging is that the mostly coextruded inner container are not diffusion-tight and thus are not very suitable for a longer storage. In addition, only a single substance can be included in the appropriate packaging. If substances must be stored, which must be mixed only at or shortly after exiting, otherwise a premature reaction takes place, so far there is no solution. This is the case for example with multi-component adhesives or certain cleaning agents or cosmetics.

The object of the invention is therefore to provide a dispenser that is simple to set up and fillable and also allows the separate, long-term storage of two (or more) substances.

This object is achieved by a dispenser with the features of claim 1. Advantageous developments are the subject of the dependent claims.

The substance dispenser according to the invention is suitable for the storage and dispensing of chemicals, such as the components of multicomponent adhesives or of paints, but also for cosmetics or pasty or liquid substances. The dispenser comprises an outer shell with a deformable outer wall and an enclosed, likewise deformable container arrangement. The deformability of the outer wall is set such that it is deformable by simply applying pressure with one hand or several fingers, but it has such a strength that allows stable storage of the dispenser. When pressurizing the outer shell, which may also be done via appropriate terminals or Klammem, it is provided that the stored in the inner container assembly substances emerge from this. This is made possible by providing an air-filled gap between the outer wall and the container assembly and uniformly communicating the pressure exerted on the outer envelope to both (or more) containers of the container assembly. In order to ensure a filling of the gap after the issue of the stored substances, the outer shell has at least one inlet valve for compensation air. Through this compensation valve, a corresponding amount of air flows into the space between the deformable outer wall of the outer shell and the container assembly enclosed by it. The proposed dispenser for substances is characterized in that the container arrangement has at least two containers for the separate storage of liquid or pasty substances. This embodiment of the dispenser allows separate storage of substances in a single dispenser. For example, this dispenser allows a two- or multi-component adhesive to be stored in a single container, as well as the two-component adhesive Stocking of particularly sensitive cosmetics, such as hair dyes, which may only be mixed on leaving the storage container, for example, to develop their nourishing effect.

In order to increase their storage time, it is additionally proposed that the outlet region of the containers has an at least extensive diffusion seal, in particular made of metal, preferably one aluminum cap or sleeve, which only pierces the dispensing head, in particular with the tips provided, when the dispenser is in use. is opened. Thus, the total bag contents are protected from access of air, wherein the opening of the seal preferably takes place with the movement of the dispensing head from an initial or storage position into the use position by latching.

In a preferred embodiment it is provided that the substances stored in the containers have the same or similar viscosities. Depending on the design of the corresponding mixing device, which may additionally be provided on the dispenser, there is thus the possibility that the discharged quantity remains largely the same. If only a small amount of a second substance, for example a hardener, is to be dispensed to a large amount of a first substance, this can be adjusted by different cross sections of the dispensing openings. By this donor thus the cumbersome storage of the substances to be mixed in separate containers is avoided. In addition, it can be ensured by the dispenser that consistently constant mixing ratios of the substances are dispensed from the dispenser. In addition to the arrangement of two containers, it is also possible to arrange more than two containers, for example, for a three-component adhesive in the dispenser.

As low is considered when the outer shell are formed of a thermoplastic material. In particular, the use of PE (polyethylene), PP (polypropylene) or PET (polyethylene terephthalate) is suitable. The (inner) containers are preferably formed from metal foil or a laminated multilayer film (so-called barrier film), wherein the containers produced with sealing seams can be produced particularly favorably and diffusion-tight. Depending on the reactivity of the stored substances, a metal coating of the plastic material may additionally be provided. Also under Frischhaltegesichtspunkte offers an appropriate coating, as this coating also an antibacterial effect can be achieved.

Advantageously, the shape of the container as a cost-effective foil bag with two, three or even four sealing seams per container bag. The two (or more) bags in be summarized a multi-chamber bag, for example, via adjacent sealing seams. As a result, a separate storage of the substances is also possible, the handling of the container assembly, for example, when inserted into the outer shell by hand or machine, however, much easier. The dispenser (with inserted and filled bags) is operated as follows. The relatively flexible outer wall of the outer shell is compressed by hand or a clamp. This creates inside the dispenser, an overpressure of, for example, 0.5 bar, which acts directly on the bag arranged there, and indeed completely uniform. Because of the air-filled intermediate space surrounding the containers, a uniform admission of both bags takes place, so that with the same outlet cross-section, an output of the same quantity of substance or of a plurality of substances takes place, which is independent of the force of the pressurization on the outer casing.

A preferred embodiment provides that the dispenser is designed as a disposable container. Such a dispenser is disposed of after the complete removal of the substance stored therein. The containers and the outer wall can be connected in at least one area, in particular pressure-tight via corresponding sealing lips. For connection, of course, a subsequent welding of the container and the outer wall can be done. This prevents that after partial emptying of the container collapse these in the housing and no longer allow complete removal of the substances from the containers. Due to the connection between the container and the outer wall, at least in a partial area, they remain erected up to complete emptying in the dispenser. This is also achieved if in each container a tube is welded, the free end also serves to connect to the common dispensing head, and liquids may have a check or fill valve.

For simplified removal and need-based mixing of the substances, it is considered favorable if an applicator connected to the outer shell is provided. The containers are connected to the applicator via channels or lines. The applicator can, for example, have two juxtaposed dispensing openings or correspondingly two or more concentrically arranged annular gaps, from which the substances are discharged separately and do not mix until they emerge from the applicator.

A further advantage is that the dispenser can be designed as a reusable container, so has interchangeable or refillable container in its interior. In order to be able to remove the emptied containers or to be able to carry out a refilling here, the dispenser has a removable dispensing head. This is designed in particular as a screw or plug-in closure or connected to the outer shell via a corresponding snap connection. In addition to a removable closure or dispensing head there is also the possibility that the outer shell, for example in the bottom area, has a flap or lid and thus allows access to the containers arranged in the interior. The closure provided on the dispenser is also advantageously designed as an applicator and thus offers the above advantages.

As compensation for the amount of substance removed, air flows into the space between the outer wall and the container at the dispenser. In order to allow rapid refilling of the intermediate space with outside air, the inlet valve is designed as a valve arranged in the outer wall or in the closure. In particular, the arrangement of a so-called ball or needle valve offers itself here as a valve. This is opened by the pressure prevailing in the container after the substance removal negative pressure or preferably by gravity by the dispenser is placed against the preferred overhead position in the use position upright again. The valve can here with the shaping of the dispensing head with or be formed, in particular in the manner of a cage for guiding a (small) ball. This design is of independent, inventive importance, as this several functions are achieved. Thus, such a ball or needle valve in the upright position of the dispenser and thus open position allows long-term storage without large pressure fluctuations (eg by temperature changes) and thus also the transport by aircraft. When filling the containers, compressed air can be applied to the equalizing valve in order to compress the foil bags flat before filling with the substance, ie to deaerate them. In the use position (overhead position), the gravity-actuated ball together with a sealing seat allows a secure seal and thus easy pressurization.

In addition, the bottom portion of the outer wall may have a rounded shape so that the dispenser is stored "overhead" standing or lying, preventing "leakage". Thus, the dispenser can not be placed "overhead" with the hinged lid open, which also prevents an unintentional "leakage". As a vent valve here is a so-called. Ball valve on.

a modified embodiment, similar to the representation in Fig. 7 ,

Fig. 1 shows an embodiment of the dispenser 10 according to the invention, which in the embodiment comprises two containers 11a, b. The containers 11a, b are arranged in an outer shell 13 of the dispenser 10, which is formed from a deformable material, for example made of PE, PP or PET. The outer wall 12 of the outer shell 13 is made easily deformable, in particular in oval shape, to be well grasped by the human hand. Since the dispenser 10 (in storage) is a stand-up container, as here in FIG Fig. 1 shown, the deformability of the outer wall 12 is selected so that this outer shell 13 still allows a stable installation of the dispenser 10. The arranged in the interior of the outer shell 13 container 11a, b are also formed of a deformable material, wherein the material thickness, however, may be very low, in particular in the manner of a film. Between the containers 11a, b and the outer wall 12 of the outer shell 13 there is an intermediate space 14 which is filled with outside air via a compensating valve 23 described below (cf. Fig. 1 , the right section illustration). The dispenser 10 also has a screw cap 10 'which supports the dispenser 10 (here with an applicator 24, cf. Fig. 6 ) and the vent hole of the balance valve 23 dustproof covers to prevent contamination during prolonged storage.

In the left-hand sectional view (centrally through the narrow side of the dispenser), the filled containers 11a and 11b can be seen, which connect with their dispensing openings 18a and b and filling valves 19 (in particular in the case of liquids) to the dispensing head 15. The dispenser 10 shown here is a disposable container, wherein the containers 11a, b are not interchangeable. To attach the lid 10 'is here Thread 16 provided (see. Fig. 2 ). The dispensing openings 18a, b for the stored substances are embodied in the form of a spout in the exemplary embodiment and permit separate dispensing of the substance stored in the containers 11a, b, so that mixing can take place only subsequently or at the outlet from the applicator 24. If the outer shell 13 and the dispensing head 15 are designed as reusable containers, after removal of the dispensing head 15 from the outer shell 13 (see latching connection 15a / 13a in the Fig. 2 and 3 ) the containers 11a, b are removed and replaced by "new" containers 11a, 11b. The dispensing head 15 or applicator 24 (cf. Fig. 6 ) has at the bottom of spike-like projections 20 which are inserted over the filling valves 19 and press them with locking of the patch on the outer shell 13 dispensing head 15 in the open position.

The compensation valve 23 shown in the right-hand sectional view is designed in the embodiment as a ball valve and allowed in the position in Fig. 1 the access of air, but prevents in the overhead-use position (see. Fig. 5 ) their exit. In addition to a version as a gravity-operated ball valve, as in Fig. 1 and 5 illustrated, it is also possible to perform the balance valve 23 as a needle valve.

In Fig. 2 the dispensing head 15 is shown in several views, as well as in two sections along the cutting lines AA (broadside) and BB (narrow side) shown above. In the left, bottom section of Fig. 2 are in the discharge openings 18a, b in contrast to the upper left sectional view in FIG Fig. 1 No filling valves are provided, since these are not absolutely necessary for the pasty substances, but for liquids. In addition, a circumferential sealing lip 15b can be seen, which with the upper edge 13b (see. Fig. 3 ) of the outer shell 13 cooperates closely and thus the entire container (except for the balance valve) designed pressure-tight. If the dispenser 10 is designed as a disposable container, instead of a thread 16 'and a permanent welding of the dispensing head 15 can be performed with the outer shell 13. In addition, there is also the possibility that the inner container 11a, b used in the outer shell 13 and the outer shell 13 is then welded. The two (or more) containers 11a, b may also be connected to the outer wall 12 in the one-way embodiment. Likewise, these can via the tube 17 leading to the discharge openings 18a, b (see. Fig. 4 ) be coupled together. These tubes 17 with openings 17 'stabilize the made of a thin-walled material such. B. foil formed container 11 a, b and prevent their collapse in advanced emptying. In the exemplary embodiment, the dispensing of the substances stored in the containers 11a, b takes place via an applicator 24 arranged centrally on the upper side of the dispenser 10.

This in Fig. 6 shown applicator 24 has two channels 28 for the separate supply of stored in the containers 11 a, b substances, wherein the output takes place at an annular gap 27 which is interrupted by a connecting web 25. This embodiment ensures a separate supply of the substances to the applicator 24 or up to its upper side with a curved applicator surface 29. Such an applicator 24 is in the DE 20 2011 002 558 U1 explained in more detail.

As already described, is located between the outer wall 12 of the dispenser 10 and the containers 11 a, b, a gap 14 which is filled with air. This space 14 ensures the uniform distribution of the force exerted on the outer wall 12 pressure, which is necessary for the removal of the substances from the containers 11 a, b. After removal of a certain amount of a substance (in the use or overhead position after Fig. 5 ) flows through the compensation valve 23 outside air into the gap 14 and on the one hand, that in the next removal of substance again a uniform pressure distribution is ensured and on the other hand, that the outer wall 12 of the dispenser 10 is returned to its original position. The raised donor 10 (as in Fig. 1 ) thus always has sufficient stability and a filled appearance.

In Fig. 4 Fig. 1 shows a preferred embodiment of the container (empty or empty) 11a, b in the manner of a foil bag which is welded to sealing seams 11c. These can have any shapes. It is also possible to combine two containers 11a, b via continuous sealing seams 11c into a two-chamber bag, which is then inserted into the outer casing 13. The outer wall 12 ultimately determines the appearance of the dispenser 10 and thus contributes to its distinctness.

In addition to the arrangement shown here of two containers 11a, b with the same volume, there is also the possibility that the containers 11a, b have different volumes. In addition, the dispensing head 15 or applicator 24 can have correspondingly diameter-reduced dispensing openings 18a, b, so that a uniform amount of substances is always dispensed when the dispenser is uniformly pressurized. In this embodiment of the dispenser 10, for example, the addition of a smaller amount of a substance to a large amount of other substances can then take place. This is useful, for example, when the dispenser 10 is used for multi-component adhesives that require only a small amount of admixing of a hardener. In addition to the use of adhesives, it is of course also possible to use the dispenser 10 for cosmetics, in which case a connection of the substances to form, for example, a care substance takes place only when it leaves the dispenser 10. about the embodiment of the applicator 24, as this in Fig. 6 is shown, then a lapse of the emerging from the dispenser 10 cosmetic substances when applied, for example, on the skin or on the lips done.

According to Fig. 5 The dispenser 10 also has an applicator 24, to which the compensating valve 23 adjoins on the right. This prevents in the overhead position with the downwardly falling sealing ball 23a against a sealing seat, the escape of air from the gap 14 of the dispenser 10, so that the containers 11a, b are pressed together with manual pressurization of the outer wall 12 and the substances are dispensed. After twisting from the overhead position (with the sealing ball 23a falling back within the cage 23b by gravity, see position in FIG Fig.1 On the other hand, an inflow of air through the equalizing valve 23 can take place. In the execution after Fig. 5 In addition, a modified form of the cover 10 "is shown, namely with a sleeve-like extension, which can be cleaned after use by the Aufsteckkappe (see. DE 20 2008 015 776 the applicant).

In addition to the configuration of the applicator 24 with a defined diameter of the dispensing openings 18a, b, the use of an adjustable system is conceivable in which the cross-section or the size of the dispensing openings 18a, b is variable depending on the amount to be dispensed. The dispenser 10 according to the invention thus represents a cost-effective alternative to dispensers 10 with pumping devices, and due to the air-filled gap 14 allows a relatively accurate dosage or a precisely adjustable mixing ratio of the substances delivered due to the absolutely identical pressure conditions, which are arranged on those in the dispenser 10 Container 11a, b act as they are in the same pressure chamber or outer shell 13.

In particular, the equalizing valve 23 (especially together with the filling valves 19 in the containers 11a, b) enables effective filling of the containers 11a, b. Thus, a compressed air connection can be applied to the equalizing valve 23, so that the intermediate space 14 of the preassembled dispenser 10 can be pressurized with air pressure. Since the outer shell 13 and the dispensing head 15 are sealed, for example, via the sealing lip 15b and the adjacent sealing edge 13b, the air pressure acts on the inserted container 11a, b and pushes them flat together (thus almost vacuum). Then, on the openings 18a, b (see in particular Fig. 2 , Medium perspective view) a (commercial) filling head for both substances are placed so that these components can be filled with virtually no air in the container 11 a, b. This is particularly important for the later, uniform delivery from the dispenser 10, but also for materials sensitive to oxidation. After removing the filling head, the filling valves close 19 (or pasty substances by itself) the discharge openings 18a, 18b, until the use or the placement of an applicator with opening on the mandrel-like extensions 20th

Fig. 7 shows a further embodiment of the dispenser 10 according to the invention, which comprises two containers 11a, b as a container assembly 11 in the embodiment. The containers 11a, b are arranged with their upper region (outlet region 13c) within an outer shell 13 of the dispenser 10, which is formed of a relatively stable plastic material, for example made of PE or PP. As in the following Fig. 1 to 6 , wherein like reference numerals are used for similar components, the downwardly adjoining outer wall 12 against the more stable outer shell 13 is made easier deformable to be well grasped and squeezed by the human hand. The deformability of the outer wall 12 is chosen so that it allows a stable installation of the dispenser 10, if not, as here, a curved bottom 10 "is provided., The arranged in the interior of the outer wall 12 container 11a, b are also formed of a deformable material, but the material thickness can be very small, in particular in the manner of a film between the containers 11a, b and the outer wall 12 is again the intermediate space 14 which is filled via the above described compensation valve 23 with outside air is (see in Fig. 1 , left sectional view). The dispenser 10 also has a lid 10 '(see also FIG Fig. 9 , in the open state), the dust-tight covering the dispenser 10 and the vent hole of the compensation valve 23 to prevent contamination during long storage.

In the right-hand sectional view (centrally through the here cylindrically shaped dispenser 10), the filled containers 11a and 11b can be seen, which merge with their discharge openings 18a, b and the discharge area 13c to a dispensing head 15. The dispensing openings 18a, b for the stored substances are formed like a spout in the embodiment and allow separate output of the stored in the containers 11a, b substance, so that a mixture can be done later in or on exit from the dispensing head 15. If the outer casing 13 and the dispensing head 15 are designed as reusable containers, the containers 11a, b can be removed from the outer casing 13 (see detent connections 15a / 13a) after removal of the dispensing head 15 and replaced by "new" containers 11a, 11b. The dispensing head 15 has at its lower portion notches 15a, which in a corresponding upper groove 13a (see also Fig. 8 ) engage the outer shell 13. In this case, a second, lower groove 13a is provided at a distance from the outlet region 13c. Compared with the position shown here, the dispensing head 15 can be pressed even further down, so that the notches then engages in the second, lower groove 13 a (see. Fig. 9 and also Fig. 11 ), whereby tips 16a described below punctures a diffusion seal 17a.

The in the left sectional view of Fig. 7 shown balancing valve 23 is executed in the embodiment as a ball valve and allowed in the position in Fig. 7 the access of air, but prevents in the overhead-use position (see. Fig. 9 ) their exit. In addition to a version as gravitation-actuated ball valve, as shown here, it is also possible to carry out the compensation valve 23 as a needle valve. An extension of the compensating valve 23 is, similar to the outlet region 13c designed as a "turret", which can serve as a filling valve 19 during filling (see. Fig. 10 ).

In Fig. 8 , Top perspective view is shown in the dispensing head 15 inserted from below Umgriffsülse 16 shown in its interior (see. Fig. 7 and 9 ) has two tips 16 a, which serve to pierce or open the diffusion seal 17 when the dispensing head 15 from the position in Fig. 7 (Latches 15a in the upper position) is pushed further down and then locked there in the lower of the grooves 13a.

In the middle perspective view of Fig. 8 the cap-like outer shell 13 is shown as a lower part of the dispensing head 15 from below. Here, the boundaries for the discharge openings 18a, b can be seen, as well as the mitangegossene cage 23b of the compensation valve 23 and a sealing lip 13b for tight connection with the outer wall 12 (see. Fig. 7 ). In the lower perspective view of Fig. 8 For example, the nozzle-shaped discharge openings 18a, b, which essentially form the discharge area 13c, and the above-mentioned filling valve 19 can be seen. The tubes 17 leading to the discharge openings 18a, b are preferably coupled to one another. These tubes 17 with openings 17 'stabilize the made of a thin-walled material such. B. foil formed container 11 a, b and prevent their collapse in advanced emptying. An additional diffusion seal 17a, in particular made of metal, is now fitted over these spouts of the discharge openings 18a, b (cf. Fig. 10 ), or sealed with a multi-layered film or vapor, so as to prevent oxygen from entering the substance for a long time. In the exemplary embodiment, the dispensing of the substances stored in the containers 11a, b is then effected via a central outlet 18c arranged on the upper side of the dispenser 10 (cf. Fig. 9 ).

As already described, is located between the outer wall 12 of the dispenser 10 and the containers 11 a, b, a gap 14 which is filled with air. This space 14 ensures the uniform distribution of the force exerted on the outer wall 12 pressure, which is necessary for the removal of the substances from the containers 11 a, b. After taking a determined amount of a substance (in the use or overhead position after Fig. 9 ) flows through the balance valve 23 outside air into the gap 14 and causes on the one hand that in the next removal of substance again a uniform pressure distribution is ensured and on the other hand, that the outer wall 12 of the dispenser 10 is returned to its original position.

In addition to the arrangement shown here of two containers 11a, b with the same volume, there is also the possibility that the containers 11a, b have different volumes. In addition, the dispensing head 15 may have correspondingly diameter-reduced dispensing openings 18a, b, so that a uniform amount of substances is dispensed with uniform pressurization of the dispenser 10. In this embodiment of the dispenser 10, for example, the addition of a smaller amount of a substance to a large amount of other substances can then take place. This is useful, for example, when the dispenser 10 is used for multi-component adhesives that require only a small amount of admixing of a hardener. In addition to the use of adhesives, it is of course also possible to use the dispenser 10 for cosmetics, in which case a connection of the substances to form, for example, a care substance takes place only when it leaves the dispenser 10. An applicator can then be used to spread the exiting from the dispenser 10 cosmetic substances during application, for example on the skin or on the lips done.

According to Fig. 9 In the overhead position, the downward falling sealing ball 23a against a sealing seat prevents the escape of air from the gap 14 of the dispenser 10, so that the containers 11a, b are pressed together with manual pressure of the outer wall 12 and the substances are discharged. After twisting from the overhead position (with the sealing ball 23a falling back within the cage 23b by gravity, see position in FIG Fig. 7 On the other hand, an inflow of air through the equalizing valve 23 can take place. The dispenser 10 is preferably stored lying after use (with opening of the diffusion seal 17).

In addition, the equalizing valve 23, together with the filling valve 19 in the containers 11a, b, enables the containers 11a, b to be filled effectively, as in FIG Fig. 10 is indicated. Thus, via the filling valve 19 to the compensation valve 23, a compressed air connection can be applied, so that the intermediate space 14 of the preassembled dispenser 10 can be acted upon with air pressure. Thus, the air pressure on the used, still empty container 11a, b acts and pushes them together flat (thus almost vacuum). Then, a (commercial) filling head for both substances can be placed on the adjacent openings 18a, b, so that these components are filled into the containers 11a, b practically without air can. This is particularly important for the later, uniform delivery from the dispenser 10, but also for the storage of oxidation-sensitive materials. After removal of the filling head nor the diffusion seals 17a, in particular in the form of aluminum caps on the nozzle-shaped discharge openings 18a, 18b placed, as well as the dispensing head 15, initially similar to the position as in Fig. 7 , wherein the diffusion seals 17a are not pierced yet. For use, the dispensing head 15 is then further pushed so that the detents 15a engage in the lower groove 13a here and the diffusion seal 17a is pierced by the tips 16a. Thus, the tips 16 a act similar to the extensions 20 in Fig. 6 , Furthermore, in each case a locking ball 21 is preferably inserted into the respective discharge opening 18 a, b, which also without spring action (see. Compression spring in Fig. 1 ) can seal the container assembly 11, as explained below.

In Fig. 11 is a modified version in a similar representation as in Fig. 7 shown. Therefore, the same reference numerals apply to similar components in a corresponding manner as the above description. In the illustration on the right here, an aluminum cap is shown as diffusion seal 17a only above the right discharge opening 18a for clarification with thicker line width. In reality, the diffusion seals 17a may be very thin, e.g. B. as a coating or vapor deposition (with SiO _x ). It is sufficient that the substance-carrying, central outlet region 13c is coated, but also the entire cap-shaped outer casing 13 may be vapor-deposited. As a result, the outer shell 13 can be injection-molded with inexpensive plastics.

As mentioned above, within the discharge openings 18a, 18b, in a particularly preferred embodiment, a respective blocking ball 21 made of metal or glass is used (cf. Fig. 10 in the starting position), which are pushed down to the use of the dispenser 10 through the here spike-shaped tips 16a down, so is opened together with the diffusion seal 17a by the dispensing head 15 is pressed (from the left position) down (in here right end position) and then locked in the lower groove 13a. In Fig. 11 In the left-hand illustration, an intermediate position is shown which corresponds to the respective blocking ball 21 after being filled with respect to the starting position Fig. 10 is pressed by the known filling head into a central constriction. As a result, the container contents are securely sealed for a long storage. Above and below this constriction small radial webs 21 'in the discharge port 18a, b are formed, so that the respective filling in the upper position of the locking ball 21 (see. Fig. 10 ) can be done quickly and unhindered and then the locking ball 21 is pressed into the middle position at the bottleneck to seal the container 11 a, b safely. For later use of the dispenser 10 then dispensing head 15 is further pressed down ( Fig. 11 , right-hand illustration), so that the tips 16a (or similar extensions 20) not only the Pierce diffusion seal, but also move the locking balls 21 from the middle constriction (sealing position) down in the extended area, so that the respective substance can flow well.
