Description

The invention relates to a decanting device for decanting liquids, in particular liquid permanent .well means, from a storage container provided with a removal cap into a portion container provided on the bottom with a filling cap.

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 an undesirable reaction of the liquid with the atmospheric oxygen.

Several of these aspects must be taken into account when decanting liquid permanent wave agent, In the first place, excessive contact with atmospheric oxygen must be avoided because the conventional permanent waving agents contain oxidizing components.

It is known, for example, when decanting liquid gas from a high-pressure storage container into lighters, to provide a filling closure designed as a valve at the bottom of the lighter and to place it directly on the removal closure of the storage container also configured 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 storage container, which in turn means that leakage losses during transfer are inevitable. 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 decanting permanent permanent wave or similar liquids due to the high overpressure required and possible leakage losses.

One possibility for decanting liquid permanent wave 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 varieties, but there is also an undesirable contact with the atmospheric oxygen.

It must be assumed that the transfer of liquid permanent wave means there is a requirement to simplify the transfer process in such a way that the user can carry it out with one hand, while avoiding liquid losses and restricting the contact of the liquid with the atmospheric oxygen in particular 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 object of the invention is therefore to provide a decanting device of the type mentioned at the outset with which decanting can be carried out quickly and easily, liquid losses being avoided completely 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.

This object is achieved in that a filling valve which can be connected to the filling closure of the portion container is arranged in a lower part of the frame, and that a stand connected to the lower part of the frame carries a removal connection part which is arranged laterally and above the filling valve at a distance and can be connected to the removal closure of the storage container.

The storage container with its removal lock 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 is present at the filling valve 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.

In order to simplify the operation, the aim is to keep the operations required for the transfer process as small as possible, for example, this is desirable. to dispense with a separate actuation of the filling valve.

For this purpose, it is provided in a further development of the inventive concept that the filling valve has an upwardly projecting, hollow filling pin that can be inserted into the filling closure of the portion container, that at least one movable, spring-loaded, standing area for the portion container from a standing surface surrounding the filling pin Valve actuating part protrudes, and that the valve actuating part is connected to a valve closure body of the filling valve. The filling valve therefore 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 plug has been 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 spigot after the portion container has been removed. This largely prevents contamination from escaping liquid.

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, spring-supported valve housing component, 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.

One embodiment has proven to be particularly advantageous of the subject of the invention, in which the storage container is provided with lateral, undercut recesses into which projections attached to the stand in the inserted state of the storage container engage in the manner of a bayonet catch. A secure attachment of the storage container to the stand is thus achieved, so that leakage of liquid is ruled out even with very improper handling and even when the device falls over.

In order to prevent the storage container from being necessarily closed 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 has a valve screw cap, which carries an inwardly projecting valve seat lip which, in the closed state, lies sealingly against a central valve seat cylinder rigidly connected to the storage container, and that the valve screw cap has longitudinal ribs on its outside which are axially parallel and which also engage in axially parallel guide ribs of the removal connection part.

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, only the rotation of the storage container, which is necessary for closing the bayonet catch, leads to the opening of the removal valve. In a corresponding manner, the extraction valve is in the opposite rotary movement locked, which is required to release the bayonet lock. In this way, not only is simplification of handling achieved in that the storage container is automatically opened when it is attached to the stand and is automatically closed again when it is removed, but it is also ensured that no liquid losses can occur when the storage container is put on or removed.

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 because of 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 at the bottom of the storage container.

In order not to leave the ventilation opening open unnecessarily long, it is designed to be closable. However, the work required for the respective opening and closing of the ventilation opening can be avoided and the ventilation process can be carried out over those time periods limited, in which a ventilation is actually necessary, namely only during the transfer of liquid into the portion container, by installing a ventilation valve in the standing area next to the filling spigot, the valve actuating part of which protrudes upwards above the standing area and this via a ventilation line with the ventilation connection is connectable in the removal connector. The storage container is only ventilated when the portion container is attached.

Further advantageous refinements of the inventive concept are the subject of dependent claims.

• Fig. 13 in a longitudinal section according to Fig. 12, 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 has a screw cap 6 with a tubular outer nozzle 7, has in its bottom a filler cap 8, which is only indicated by dashed lines in FIG becomes.

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 detail in FIGS. 2-4, the filling valve 4 has a hollow filling pin 14 which projects upwards and 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 7, 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 projects 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, which are connected to a lower, movable valve housing part 18, protrude from the axis of the standing surface 15. 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 located 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 poppet-shaped valve seat 27 at the lower end of the filling pin 14. When the portion container 5 is placed on the base 15, as shown in FIG. 3, 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 lifted off the valve seat 27. The liquid located in the interior of the filling valve 4 and flowing through the hose line 13 rises into the portion container 5 up to the desired height, which can be determined by markings on the portion container 5. Once the one you want 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 embodiment shown in FIGS. 5 and 6, in which the same reference numerals are used for the same parts as in FIGS. 1-4, differs from the previously described embodiment in that the valve closure body 24 with 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 a double valve closure achieved, but it is also prevented that the liquid remaining in the filling pin 14 after the filling valve 4 closes can dry out.

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

5 and 6 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.

The storage container 12 shown in the example according to FIG. 1 has a sealing plug 31 in the original, closed state (Fig.la) within its removal closure attached to the bottom, which can be pressed into the interior of the container when the storage container 12 is placed through a projection 32 of the removal connection part 10. 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.

Another way of venting the reservoir 12 is shown in FIG. 8. A ball check valve 38, which forms a ventilation valve and allows the corresponding amount of air to penetrate when liquid is removed from the reservoir 12, is arranged in the removal connection part 10 in addition to a removal opening 37 connected to the hose line 13.

When the storage container 12 is designed according to FIG. 9, no closable ventilation opening or a ventilation valve 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. The film bag 39 coincides with the progressive removal of liquid. 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. 10-12, 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. 12). The storage container 12 (FIG. 10 a) has a ventilation pipe 43 which projects upwards from its removal closure and which, when the storage container 12 is in the attached state, is connected to the ventilation line 41 in a manner described in more detail later.

As shown in Fig. 11 in an enlarged representation in detail, a ventilation valve 44 is arranged in the base 15 of the removal connection part 4 next to the filler pin 14, the valve actuating part of which is a plunger 45, which at its lower end rests against an annular valve seat 46 from below Valve closing body 47 is connected and is provided at its upper end with spring arms 48 which extend in a star shape outwards and downwards. The part of the valve tappet 45 which projects 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 fully seated and thus the filling pin 14 is tightly connected to the filler cap 8 of the portion container 5.

12 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 53ades 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 and thus the ventilation valve 44 is opened, the space above the liquid level in the reservoir 12 is ventilated in this way via the ventilation line 41, so that liquid can flow into the portion container 5. The liquid flows thereby 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 protruding cylinder extension 56 is provided on the container cap 55 attached to the reservoir 12, which sealingly engages in an axially extending sealing groove 57 of the valve screw cap 50.

13 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. 10 to 12, the storage container 12 has lateral undercut recesses 58 (FIG. 10a) into which projections 59 attached to the stand 9 in the inserted state of the storage container 12 engage in the manner of a bayonet catch. The reservoir 12 must therefore be rotated after insertion to be connected to the stand 9. When the reservoir 12 is inserted, however, the longitudinal ribs 53 of the valve screw cap 50 also engage with the guide ribs 53a of the removal brought connecting 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. Only through this screwing movement does the valve seat lip 51 become disengaged 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 put on 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 locking 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.
