Description

The invention relates to a decanting device for decanting liquids, in particular liquid permanent waving agent, of the type specified in the preambles of the independent claims 1 and 2. Such a decanting device is already known from DE-GM 81 20414.

The transfer of liquids from a larger storage container into a smaller portion container is associated with increased difficulties in all those applications in which a loss of liquid which may occur during transfer is perceived as particularly troublesome, for example because of the contamination which occurs as a result, or if the transfer occurs when the transfer is free Contact with the air causes disadvantages, for example the escape of harmful vapors or unpleasant smells, or if there is a risk of an undesirable reaction of the liquid with the atmospheric oxygen.

Several of these points of view are to be taken into account when decanting liquid permanent waving agent, in the first place excessive contact with atmospheric oxygen must be avoided because the conventional permanent waving agents contain oxidizing constituents.

It is known, for example, when transferring liquid gas from a high-pressure storage container into lighters, to provide a filler cap designed as a valve at the bottom of the lighter and to place it directly on the removal cap of the storage container, which is also designed as a valve. As a result of the pressure exerted, the dispensing closure of the storage container opens and liquid gas under pressure can flow into the gas container of the lighter. This type of transfer requires a relatively high pressure in the reservoir, which in turn means that leakage losses during transfer are unavoidable. These leakage losses are largely insignificant in the example of filling gas lighters mentioned, because the escaping liquid gas evaporates immediately and has no unpleasant or harmful effects. However, this measure is not suitable for the transfer of liquid permanent wave or similar liquids due to the high overpressure required and possible leakage losses.

One possibility for transferring liquid permanent waving agent or the like is to provide the storage container with a tubular pouring spout which is inserted into a filling opening of the portion container. In this case, however, it is necessary to lift and topple the storage container with each refilling process, whereby there is not only the risk of liquid loss but also an undesired contact with the atmospheric oxygen.

It must be assumed that the transfer of liquid permanent waving agent requires that the transfer process be simplified in such a way that the user can carry it out with one hand, with the avoidance of liquid losses and the greatest possible restriction of the contact of the liquid with atmospheric oxygen dosing of the amount of liquid accommodated in the portion container is to be made possible in a simple manner so that the user can remove the amount of liquid provided for the respective application.

The decanting device known from DE-GM 81 20 414 for decanting liquids from a storage container provided with a dispensing closure into a portion container provided with a filling closure on the bottom has a frame in which a filling valve which can be connected to the filling closure of the portion container is arranged, which has a hollow filling pin which projects upwards and can be inserted into the filling closure of the portion container, and a stand connected to the frame. Here too, however, the liquid to be transferred from the storage container into the portion container is under high pressure, which is built up with the aid of a feed pump.

The object of the invention is to provide a decanting device of the type mentioned at the outset, with which decanting can be carried out quickly and easily using the hydrostatic pressure, liquid losses being completely avoided and contact of the liquid with atmospheric oxygen being largely ruled out. No handling of the storage container should be necessary during and between the individual refilling processes.

Solutions to the problem are given in the characterizing part of claims 1 and 2, respectively. Advantageous embodiments of the invention can be found in the subclaims.

One solution to the problem is that at least one movable, spring-loaded valve actuation part protrudes from a stand surface surrounding the filling pin for the portion container which can be vented through its discharge nozzle, the stand carries a removal connection part arranged laterally and above the filling valve, with which the removal closure of the storage container is directly detachably connected, and that the storage container has a closable ventilation opening on its wall opposite the removal closure.

Another solution to the problem is that at least one movable, spring-loaded valve actuation part protrudes from a stand surface surrounding the filler pin for the portion container which can be vented through its discharge nozzle, and the stand protrudes laterally and above the filling valve at a distance from the removal connection part to which the removal closure of the storage container is directly detachably connected, in the removal connection part of the stand next to a removal opening there is a ventilation connection which, when the storage container is fitted, has a ventilation pipe protruding upwards from the removal closure of the storage container in the interior of the container there is a tight connection, and that a ventilation valve is arranged in the standing area next to the filler pin, the valve actuating part of which projects upward above the standing area, and which can be connected to the ventilation connection in the removal connection part via a ventilation line.

The storage container with its removal closure is connected to the removal connection part. The flow connection between the removal connection part and the filling valve can be made in a simple manner through a line, for example a hose. The difference in height between the storage container and the filling valve ensures that the liquid at the filling valve is present with a relatively low overpressure which is sufficient for the refilling process. The liquid rises in the connected portion container from the filler cap attached to the bottom until the desired liquid level is reached in the portion container. The liquid comes into contact with the atmospheric oxygen as little as possible, especially since the liquid in the portion container slowly rises and the liquid level in the portion container remains smooth. Any free liquid jet with the resulting considerable increase in surface area is avoided.

The operation of the transfer device is relatively simple, since only a few steps are required during the transfer process. In particular, the filling valve does not need to be operated separately.

The filling valve opens automatically as soon as a portion container has been placed, the arrangement of the valve actuation parts in the base for the portion container ensures that the filling valve is only opened when the portion container is placed on the base and thus ensures that the Filling spigot was completely inserted into the filling cap of the portion container. In a corresponding manner, the filling valve closes as soon as the portion container is lifted off the standing surface, so that it is prevented that liquid can still escape from the filling pin after the portion container has been removed. This largely prevents contamination from escaping liquid.

In order to ensure a free flow of the liquid to be decanted, various measures are possible to ventilate the storage container when liquid is drawn off.

This ventilation is achieved in the simplest manner in that the storage container has a closable ventilation opening on its wall opposite the removal closure. Since the free surface of the liquid in the storage container is particularly large due to its size, and because the liquid remains in the storage container longer than the portion container, it is particularly important that the liquid level in the storage container is moved as little as possible. It is particularly important for this that the liquid is drawn off from the underside of the storage container.

In order not to leave the ventilation opening open for an unnecessarily long time, it is designed to be closable. However, the work required for opening and closing the ventilation opening can be avoided and the ventilation process can be limited to those periods in which ventilation is actually necessary, namely only during the transfer of liquid into the portion container by in the stand area next to the filling spigot Ventilation valve is attached, the valve actuating part protrudes above the standing surface and which can be connected to the ventilation connection in the extraction connection part via a ventilation line. The storage container is only ventilated when the portion container is attached.

According to one embodiment of the invention, the valve actuating part is connected to a valve closure body of the filling valve.

According to a particularly advantageous embodiment of the filling valve, it is provided that the valve actuating part and the valve closure body are connected to a lower, movable valve housing part supported on a spring, and that the lower, movable valve housing part is connected to an upper, frame-fixed, with the base and the filling pin Valve housing part is connected by a movable valve housing seal, which is preferably a bellows. This eliminates the need to seal lead-through points for moving components on the filling valve, which could lead to leaks after a long period of operation.

An embodiment of the subject matter of the invention has proven to be particularly advantageous in which the storage container is provided with lateral, undercut recesses into which projections mounted on the stand in the inserted state of the storage container engage in the manner of a bayonet catch. This ensures that the storage container is securely attached to the stand, so that even if it is handled improperly and even if the device falls over, liquid cannot escape.

In order to prevent the storage container from being closed necessarily before it is removed from the decanting device, which would lead to contamination and loss of liquid, it can be provided in a further advantageous embodiment of the inventive concept that the removal closure of the storage container is a removal valve and one Has valve screw cap, which carries an inwardly projecting valve seat lip, which in the closed state seals against a central valve seat cylinder which is rigidly connected to the storage container, and that the valve screw cap has longitudinal ribs running parallel to the outside, into which guide ribs of the removal connecting part also running parallel to the axis engage.

Since the valve screw cap is axially displaceable by the interlocking ribs, but is non-rotatably connected to the removal connection part of the stand, the rotation of the storage container, which is necessary for closing the bayonet lock, leads to the opening of the removal valve. In a corresponding manner, the removal valve is closed during the opposite rotary movement that is required to release the bayonet lock. This not only simplifies handling by automatically opening the storage container when it is attached to the stand and automatically closing it again when it is removed, but it also ensures that no liquid losses can occur when the storage container is put on or removed.

• Fig. 12 in a longitudinal section according to Fig. 11, the removal valve of the storage container in the closed state.

The decanting device shown in FIG. 1 has a frame or housing 1 consisting of two housing shells, the lower frame part 2 of which has a filling valve 4 within a raised edge 3. A bottle-shaped portion container 5, which consists of at least partially transparent plastic and carries a screw cap 6 with a tubular discharge nozzle 7, has in its bottom a filler cap 8, which is only indicated by dashed lines in FIG. 1 and which, when the portion container 5 is placed on the filler valve 4 is opened.

From the other end of the lower frame part 2, a stand 9 protrudes upwards and carries a removal connection part 10 there, to which a removal closure 11 of a storage container 12 can be connected. The removal connection part 10 is connected to the filling valve 4 via a hose line 13.

As can be seen in FIGS. 2 to 4 in detail, the filling valve 4 has an upwardly projecting, hollow filling pin 14 which protrudes from an essentially horizontal standing surface 15 for the portion container 5. When the portion container 5 is put on, the filling pin 14 is inserted into the filling closure 8 of the portion container 5, which is provided with a central recess 16 and is made of elastic material, for example rubber. The part of the filler cap 8 which projects into the interior of the portion container 5 has two closure flaps 8a, 8b which can be moved laterally from a closed position (FIG. 2) against their own spring force into an open position (FIG. 3). In the position shown in FIG. 3, the filling pin 14 protrudes into the portion container 5, so that the bore of the filling pin 14 is connected to the interior of the portion container 5.

Three valve actuation parts 17 protrude from the base 15 and are connected to a lower, movable valve housing part 18. The lower valve housing part 18 is supported via a helical spring 19 on an insert 20 arranged in the lower housing part 2.

The filler pin 14 and the base 15 are connected to an upper, valve body part 21 fixed to the frame, preferably made in one piece. The two valve housing parts 18 and 21 are tightly connected by a bellows 22, but are movably connected. The hose line 13 opens into the space closed by the bellows 22 and lies between the two valve housing parts 18 and 21.

In a central bore 23 of the lower valve housing part 18, a valve closure body 24 is inserted, the hemispherical head 25 of which forms an arched sealing surface 26 on its outside, which is in engagement with a hollow conical valve seat 27 at the lower end of the filler pin 14. When the portion container 5 is placed on the base 15, as in FIG. 3 shown, the valve actuation parts 17 are pressed down; they take the lower valve housing part 18 and the valve closure body 24 with them, so that the head 25 is raised from the valve seat 27. The liquid located in the interior of the filling valve 5 and flowing through the hose 13 rises into the portion container 5 up to the desired height, which can be fixed on the portion container 5 by markings. As soon as the desired liquid level in the portion container 5 is reached, this is removed again and all parts return to the position shown in FIG. 2.

The exemplary embodiment shown in FIGS. 5 and 6, in which the same reference numerals as in FIGS. 1 to 4 are used for the same parts, differs from the previously described exemplary embodiment in that the valve closure body 24 has a pin projecting into the filler pin 14 28 is connected, which is connected at its upper end in the closed state with an annular sealing surface 29 of the filling pin 14. As a result, not only is double valve closure achieved, but it is also prevented that the liquid remaining in the filling pin 14 after the filling valve 4 has closed can dry out.

As in the previously described embodiment, the valve closure body 24 is inserted in the bore 23 of the lower valve housing part 18 in a sealing and axially non-displaceable manner.

5 and 6 also show that the two closure flaps 8a and 8b of the filler closure 8 are pressed into their closed position (FIG. 5) by a surrounding rubber ring 30.

In the original, closed state (FIG. 1a), the storage container 12 shown in the example according to FIG. 1 has a closure plug 31 within its removal closure attached to the bottom, which is pushed into the interior of the container by a projection 32 of the removal connection part 10 when the storage container 12 is placed on it can. The removal closure 11 has an external thread 33 which carries a screw cap 34 in the closed state (FIG. 1a). After the screw cap 34 has been removed, the thread 33 is screwed into a connection thread 35 on the removal connection part 10, the sealing plug 31 being pressed upwards. The reservoir 12 is then connected to the hose line 13.

In order to be able to ventilate the storage container 12 when removing liquid, a closable ventilation opening 36 is provided on its upper side.

FIG. 7 shows, in an enlarged partial section according to FIG. 6, parts of the filling valve 4 and the filling closure 8 of the portion container 5.

When the storage container 12 is designed according to FIG. 8, no closable ventilation opening is required. The liquid is contained in the storage container 12 in a foil bag 39 which is tightly connected to the removal closure 11. As the liquid withdrawal progresses, the film bag 39 coincides. Contact of the liquid contained in the film bag 39 with the surrounding air, which can flow into the storage container 12 through a small ventilation hole 40, is completely prevented.

In the exemplary embodiment according to FIGS. 9 to 11, in addition to the hose line 13 intended for the liquid, a ventilation line 41 is provided which leads from the filling valve 4 to the removal connection part 10. The ventilation line 41 is connected to a hollow needle 42 at the bottom of the removal connection part 10 (FIG. 11). The storage container 12 (FIG. 9) has a ventilation pipe 43 which projects upward from its removal closure and which, when the storage container 12 is in the connected state, is connected to the ventilation line 41 in a manner described in more detail later.

As shown in FIG. 10 in an enlarged representation in detail, a ventilation valve 44 is arranged in the standing area 15 of the removal connection part 4 next to the filler pin 14, the valve actuating part of which is a tappet 45, which at its lower end rests with an annular valve seat 46 from below from below Valve closing body 47 is connected and at its upper end is provided with spring arms 48 which extend in a star shape outwards and downwards. The part of the valve tappet 45 protruding beyond the standing surface 15 is actuated from the bottom of the portion container 5 placed on it, so that the ventilation line 41 is only opened when the portion container 5 is placed completely on and thus the filling pin 14 is also tightly connected to the filler cap 8 of the portion container 5 is.

11 shows in detail the structure of the removal closure of the storage container 12. The removal closure here is a removal valve 49 which has a valve screw cap 50 which carries an inwardly projecting valve seat lip 51. In the closed state, the valve seat lip 51 lies sealingly against a central valve seat cylinder 52 rigidly connected to the reservoir 12. The valve screw cap 50 has on its outside axially parallel longitudinal ribs 53, in which likewise axially parallel guide ribs 53a of the removal connection part 10 engage, which in the exemplary embodiment shown are designed as webs between slots of the removal connection part 10.

The valve seat cylinder 52 is connected to the ventilation tube 43 and is closed at its lower end with a membrane 54, which is perforated when the storage container 12 is placed through the hollow needle 42, in order to establish a connection between the hollow needle 42 connected to the ventilation line 41 and the ventilation tube 43 . As soon as a portion container 5 is placed on and thus the ventilation valve 44 is opened, the space above the liquid level in the reservoir 12 is opened this way ventilated via the ventilation line 41 so that liquid can flow into the portion container 5. The liquid flows from the reservoir 12 down through the gap released between the valve seat lip 51 and the valve seat cylinder 52 into the removal opening 37, to which the line 13 is connected.

In order to produce a sealing closure between the valve screw cap 50 and a container cap 55, an axially projecting cylinder extension 56 is provided on the container cap 55 attached to the storage container 12 and engages sealingly in an axially extending sealing groove 57 of the valve screw cap 50.

FIG. 12 shows the closed position, in which the valve seat lip 51 bears sealingly at the lower end on the outside of the valve seat cylinder 52. When the valve screw cap 50 is screwed down, the annular gap for the removal of the liquid between the valve seat lip 51 and the valve seat cylinder 52 is released.

In the exemplary embodiment according to FIGS. 9 to 11, the storage container 12 has lateral undercut recesses 58 (FIG. 9) into which projections 59 which are attached to the stand 9 in the inserted state of the storage container 12 engage in the manner of a bayonet catch. The storage container 12 must therefore be rotated after insertion in order to be connected to the stand 9. When the storage container 12 is inserted, however, the longitudinal ribs 53 of the valve screw cap 50 are also brought into engagement with the guide ribs 53a of the removal connection part 10. When the reservoir 12 is then rotated to engage the bayonet catch parts 58, 59 and thus establish a firm connection between the reservoir 12 and the stand 9, the valve screw cap 50 is rotated relative to the reservoir 12 and thereby screwed down. It is only through this screwing movement that the valve seat lip 51 disengages from the valve seat cylinder 52 and releases the removal gap so that liquid can escape from the reservoir 12 into the line 13. This prevents any loss of liquid when the container is placed and when it starts to be removed.

In a corresponding manner, however, any loss of liquid is also prevented at the end of the removal because the reservoir 12 must necessarily be rotated before being removed from the stand 9 in order to disengage the bayonet fitting parts 58, 59. During this rotary movement, the valve screw cap 50 is turned upwards into its closed position, so that it is ensured that the valve seat lip 51 and the valve seat cylinder 52 are in sealing engagement before the reservoir 12 can be removed.

When the storage container 12 is removed, the hollow needle 42 is pulled out of the membrane 54, the opening of which closes tightly again.
