Description

Hand-operated dispenser for pasty to fluid masses and docking container therefor

The invention initially relates to a hand-operated dispenser for pasty to fluid masses with a pumping chamber and at least one outlet valve and a storage chamber with a follower piston, wherein the dispenser for the discharge of two different masses, a first mass and a second mass is designed.

From DE 10222356 Al a genus in accordance dispenser is known in which two different pasty masses are arranged one above the other in a container.

The invention has for its object to further develop a genus in accordance with modern donors vorsvorteilhaft.

This object is achieved first and foremost in a dispenser having the features of claim 1, wherein it is based on the fact that a movable separating body is arranged between the first and the second mass.

The separator prevents a possible reaction of the different masses in the container. The two different masses can be stored separately from each other until their output. They can, for example, before the issue, but possibly also after the issue, be associated with each other. In this case, it is initially even possible that the separating body is mounted movably or firmly. It is preferred that the separating body is movably mounted.

In a movably mounted or arranged separating body of this is shifted in the course of issuing the mass. For example, in the direction of the outlet opening. As a result of the displacement of the separating body, the pressure can be transmitted from the first mass to the second mass, thereby promoting the second mass, for example.

As an alternative or in addition to the previously described embodiment of a dispenser, the invention also proposes, for use-advantageous embodiment, that the second mass is introduced into the first mass after the outlet valve. The masses are therefore ultimately applied together to a surface for application, but the merger of the first and second mass happens only after the exhaust valve of the pumping chamber.

Because the second mass is introduced into the first mass only after the outlet valve of the pumping chamber, it is not necessary for the second mass to pass through the pumping chamber of the dispenser. This can, for example, the sensitivity of the mass with regard to mechanical deflection are taken into account. However, it is also possible if, for example, the masses react in a certain way with one another, thereby achieving that the reaction of the masses only occurs after the outlet valve of the pumping chamber. Accordingly, it is also not necessary, although possible, for the second mass to be arranged in the flow direction of the (first) mass in front of the pumping chamber. But it can also be promoted in the case of such an arrangement in front of the pumping chamber in as it were in the bypass to the pumping chamber.

In a further embodiment, which can be realized as an alternative or in combination with the first and / or second embodiment, the invention also proposes that the second mass be received in a second container which can be docked to the container for dispensing the second mass. By such a configuration, a dispenser may initially be optional for dispensing only one Mass or for the output of two masses are operated. Without that the actual body of the dispenser, which thus has the pantry and the pumping chamber to change, or that is something to introduce them. Furthermore, the first mass can also be brought into connection with different quantities of the second mass, namely through smaller or larger docking containers. In the course of the application of the first mass, the docking container can also be exchanged so that a first type of second mass is output together with the first mass over a first period of time and a second type of second mass is output together with the first mass over a second period of time becomes.

In the dispenser, for example, a basic mass is taken up, which can be mixed with different additional masses which are accommodated in the docking container.

The further explained features may be a development to one of the above-described embodiments, but in principle also independently of this each have meaning.

Thus, it is preferred that the outlet valve of the pumping chamber is arranged at the separation point between the two containers or chambers for the different masses. In the case of a dockable container, this can be easily removed or separated from the actual dispenser, without the second mass then uncontrollably exiting the dispenser.

The ratio of the two masses may be selected such that the second mass is provided in the docking container or the dispenser until the first mass has been emptied. Thus, a dispenser can be operated with one and the same docking container until the first mass has been emptied. As already mentioned in principle, but can also be provided that a donor with a Docking container is operated, which is intended only for a part of the first mass. However, it may remain on the dispenser after emptying, in which case the docking container is only penetrated by the first mass.

It is further preferred that the separating body is designed in the form of a follower piston. Only in this case, he is preferred atypically used insofar as the movement of the separating body or the follower piston is not carried out by negative pressure or suction, but by the pressure of the first mass on its side facing away from the dispenser outlet.

The separating body is also preferably adapted to the basic contour of the docking container, wherein the docking container in a preferred embodiment has a circular cross-section.

In further detail, the separating body is preferably displaceable relative to a dispensing tube. In this case, the dispensing tube can be arranged centrally in the docking container and thus penetrate the separating body. The separating body, for example in the mentioned shape of a piston, thus has a, for example, central, opening, which is penetrated by the dispensing tube. The dispensing tube forms a kind of separating body or piston guide tube.

The dispensing tube is also advantageous in that the first mass can pass through it and, because of an opening in the dispensing tube - first - before the outlet opening then the second mass is mixed with the first mass. Regardless of this specific embodiment, however, the measure of having the first and the second mass meeting each other immediately before the outlet opening is also of fundamental importance. As also basically mentioned above, it is preferred that the separating body is arranged only beyond the outlet valve, belonging to the pumping chamber of the dispenser, and viewed in the flow direction of the mass. In this case, moreover, it is preferred that the basic flow direction of the mass in the container, for example, docking container, for the second mass and the storage space for the first mass extend at an angle to one another. Further preferably, an axis extending in the longitudinal extent of the dispenser at an angle of 90 ° to the axis extending in the longitudinal axis of the chamber for the second mass or the docking container.

In addition, it is preferred that the docking container for the second mass has its own inlet valve. Through this inlet valve, the first mass of the first container after penetrating the outlet valve of the dispenser - first - penetrate into the docking container. This again supports the previously mentioned advantageous clean separability of docking container and dispenser.

Preferably, the inlet and / or the outlet valve is designed as an elastic return valve. It is thus basically possible to use the same or the same intake valves or exhaust valves in the pumping chamber and the docking container. Both the inlet valve of the docking container and the outlet valve of the dispenser can be actuated by the pressure of the first mass. Only the restoring force of the valves formed of elastic material displaced by this decrease in pressure in its closed position.

In the case of the docking container this can be connected by a push-in connection with the first container. This is preferably designed so that it takes place in a direction transverse or perpendicular to the direction of enforcement of the first and second mass in the docking container. The up- putting or losing takes place as it were with a shearing movement, which also allows a favorable separation.

Deviating from this, it is also possible to provide a locking of the docking container with the dispenser. For example, via a releasable latch button. Regardless of the described designs, it is also possible to provide the docking container operationally non-detachable with the dispenser or even partially in one piece with the dispenser.

The invention further relates to a docking container for docking to a dispenser, in particular to a dispenser according to one of the above-described embodiments. Here, the docking container is characterized in that it contains a (second) pasty mass and has an inlet and an outlet opening.

In such a docking container, it proves to be advantageous that in any case the inlet opening valve is closed. Furthermore, it can also be provided that the outlet opening is sealed, for example, with a tamper-evident seal. The inlet valve ensures that no mass can escape from the docking container until a docking device is attached to a dispenser or when a docking device is removed from the docking station. Likewise, the inlet valve also prevents contaminants from entering the docking receptacle prior to use of the docking receptacle.

Advantageously, the docking container has a dispensing tube formed therein and extending to the outlet opening of the docking container. In addition, the docking container preferably contains a separating body which can be displaced in the direction of delivery. This can, as already mentioned in principle, be designed in the form of a follower piston. In this case, the follower piston is designed such that the docking container can be almost completely emptied by the second mass. The second mass is preferably introduced through openings in the strand of the first mass, which is pressed through the ex giblets issuing. This creates an output mass having circumferentially distributed stripes of the second mass. The number of strips of the second mass on the strand of the first mass depends on the number of openings in the dispenser tube.

The invention will be explained in more detail below with reference to the attached drawing, which represents only one embodiment. Show it:

Fig. 7 is a view corresponding to FIG. 6, but here the dispenser was actuated and Fig. 8 is a perspective view of a product produced from the dispenser strand, which consists of two different masses.

With reference to FIGS. 1 to 7, a possible embodiment of a dispenser 1 with a docking container 2 will be described. The dispenser 1 has a first container 3, which contains a first mass 4. The first container 3 forms for receiving the first mass 4 from a storage chamber, which is closed in a known manner by a follower piston 5. The follower piston 5 is associated with a fully filled dispenser 1 the end of the first container 3, which forms a footprint 6 for the dispenser 1. At the end of the storage chamber facing away from the base 6, the first container 3 forms a valve 7. The valve 7 is closed in the basic position of the dispenser 1. The valve 7 is surrounded by a wall 8 of the first container 3. Between the valve 7 and the wall 8, an annular space is formed. In the annular space between the valve 7 and the wall 8 projects a closure head 9 into it. The closure head 9 is adapted in the end region to the inner diameter of the wall 8. In the unactuated position, this area is covered by the wall 8 such that the closure head 9 can no longer be removed from the annular space. For this purpose, the wall 8 tapers at the free end and at the same time forms a stop for the closure head 9. The closure head 9 is received in such a way from the first container 3, so that the closure head 9 in the direction of the follower piston 5 (arrow direction x) can be actuated. The closure head 9 can be moved so far in the direction of arrow x until the free end abuts against the horizontally extending in the figures end portion of the storage chamber, in which the valve 7 is arranged (see in particular Fig. 7). From FIG. 3 it can be seen that the dispenser 1 has a substantially circular cross-section. Thus, the dispenser 1 has a substantially cylindrical basic contour. However, as can be seen in particular from FIGS. 4, 5, 6 and 7, the closure head 9, in the drawings on the right-hand side, has a step section 10. In the vertically running wall of the step portion 10, an output opening 11 for the first mass 4 is arranged, which is closed by an outlet valve 12. The outlet valve 12 is formed by a return valve and held by a recorded in the closure head 9 head inner part 13 in a known manner.

The head inner part 13 forms a delivery tube 14, which extends in the longitudinal direction of extension of the first container 3. The head inner part 13 is fixedly connected via a catch 15 with the closure head 9. For this purpose, an annular bead formed by the head inner part 13 engages in an annular groove which is shaped as it were, which is formed by the closure head 9.

The free end of the dispensing tube 14 is spaced from the valve 7 so that the head inner part 13 can be displaced in the direction of the arrow x, as previously mentioned, and the free end is surrounded by an upper end of a bellows 16. The lower end of the bellows 16 surrounds the seat of the valve 7. From the bellows 16, the pumping chamber 17 is formed. The bellows 16 acts on the closure head 9 against the arrow direction x and thus displaces the closure head 9 back to the starting position after an actuation.

As can be seen in particular from FIG. 3, the closure head 9 forms laterally of the step section 10, grooves 18 extending in the longitudinal direction of the container 1. In the grooves 18, a protruding edge portion 19 of the second dockable container 20 can be inserted. As can be seen, for example, from FIGS. 1 and 2, the edge area 19 of the Dockbehältnisses 20 beyond the closure head 9 and thus forms a handle portion 21. The edge region 19 with the grip portion 21 has a substantially rectangular base surface in the direction of view of FIG. In contrast, essentially the docking container 20 is cylindrical. The docking container 20 is to be understood as a separate container, which contains a second mass 22 and can be brought into contact with the dispenser 1.

The docking receptacle 20 forms at its end assigned to the edge region 19 an inlet opening 23 which is closed by an inlet valve 24 in the form of a return valve. The inlet valve 24 is received by a receiving part 25, which is arranged in the docking container 20. The receiving part 25 forms distributed on the circumference a plurality of through openings 33, through which the first mass 4, which has already passed the inlet valve 24, can be promoted. At its other end, the docking receptacle 20 forms an outlet opening 26, which is formed by a dispensing tube 27. The dispensing tube 27 is arranged centrally in the docking container 20 and is surrounded at the end, in the direction of the inlet opening 23, by a separating body T in the form of a follower piston 28. The separator T or the follower piston 28 limits the pantry in the docking container 20 for the second mass 22. By the separator T, the first mass 4 as long as spatially separated from the second mass 22, until this is just before the issue of the two masses 4, 22 be associated. The dispensing tube 27 is stabilized on the inner wall of the docking container 20 by webs 29. This may be, for example, three webs 29, which are arranged in an equal angular relationship to each other around the dispensing tube 27 (see Figure 2). Furthermore, the dispensing tube 27 forms slot-like openings 30 at the end in the direction of the dispensing opening 26. This may be, for example, three apertures 30, which, like the webs 29, also behave at an equal angle. are offset from each other, however, the openings 30 have an angular offset to the webs 29. Thus, the openings 30 and the webs 29 do not overlap. Through the openings 30, the second mass 22 can enter the dispensing tube 27.

The following mode of action of the dispenser 1 occurs in conjunction with the docking container 20:

As can be seen from FIG. 4, the dispenser 1 can be brought into contact with the docking container 20. For this purpose, the docking container 20 is inserted in the direction of arrow x with its edge region 19 in the grooves 18. The dispenser 1 can be operated both with and without docking container 20. However, should the dispenser 1 be operated without docking container 20, then the dispenser 1 will only serve to dispense a mass 4. However, in conjunction with the docking container 20, the dispenser 1 may be used to dispense another mass 22 in conjunction with the first mass 4 become.

Starting from FIGS. 1-6, the dispenser 1 is in the unactuated position. If the closure head 9 is now actuated in the direction of the arrow x, the first mass 4 located in the pumping chamber 17 is pumped through the dispensing tube 14 past the outlet valve 12 through the dispensing opening 11. From there, the first mass 4 arrives at an upstream docking container 20 through the inlet opening 23 past the inlet valve 24 into the docking container 20. A portion of the first mass 4 engages the separating body T in the form of the follower piston 28 and another part of the first Mass 4 is pumped through the dispensing tube 27. The exhaust valve 12 and the intake valve 24 are actuated by the first mass 4. Likewise, the first mass 4 is acted upon by the operation of the dispenser 1 against the follower piston 28 and displaces this in the direction of the discharge opening 24. Thus, the second mass 22 through the openings 30 in the Ausgaberöhr- 27 pumped. From the dispensing opening 26, a mass strand consisting of two masses 4, 22 can be conveyed which, for example, is formed in such a way as is illustrated graphically in FIG. Through the openings 30 small strands 31 are applied from the second mass 22 to a main strand 32 of the first mass 4. The number of small strands 31 on the main strand 32 depends on the number of openings 30.

After the loading of the closure head 9 in the direction of arrow x this is shifted back by the elastic bellows 16 back into the starting position (see Figures 1 - 6). By the displacement of the closure head 9 opposite to the arrow x, the valve 7 opens and the first mass 4 again fills the pumping chamber 17. Along with the penetration of the first mass 4 in the pumping chamber 17, the follower piston 5 also moves in a known manner against the direction of the arrow x.

All disclosed features are essential to the invention. The disclosure of the associated / attached priority documents (copy of the prior application) is hereby also incorporated in full in the disclosure of the application, also for the purpose of including features of these documents in claims of the present application.
