Description

Brief indication: The dispensing of portions of liquid, in particular pasty substance.

According to a first aspect thereof, the present invention relates to a self-closing valve assembly according to the preamble of claim 1, and to a container with a pump provided with such a valve assembly.

DE 40 35 922 and US 5 819 990 disclose containers with an integral pump with which the substance can be pumped out of the storage chamber of the container and can be dispensed at a dispensing opening. With these known containers, a self-closing valve assembly is provided at the location of the dispensing opening.

When the pump is operated, the pressure of the substance causes the valve assembly to open, after which the valve assembly automatically closes.

The known containers are not entirely satisfactory. For example, a disadvantage is that the valve assemblies of these known holders 15 do not always exhibit the desired closing action. As a result, the known containers are for instance less or not suitable for dispensing highly oxidizing substances, such as, for example, hair dye. Furthermore, the known valve assemblies are difficult to manufacture if a good closing effect is to be achieved.

Another drawback concerns the construction of the known containers, which is relatively complex, which is disadvantageous in particular for disposable containers.

The first aspect of the invention aims to provide an improved self-closing valve assembly, as well as a container with pump provided with such a valve assembly. In particular, the first aspect of the invention provides for the use of such a container for dispensing hair dye.

The present invention achieves the above object by providing a self-closing valve assembly according to claim 1.

-2-

Preferably, the sealing surface of the stationary body is provided adjacent to the end face of the stationary body, such that the end face forms a continuous surface with the outer surface of the surrounding valve body.

This embodiment ensures that only the end face of the stationary body is exposed to the ambient air when the valve assembly is closed. If any residues of the substance that adhere to that end face harden, those cured residues hardly block the operation of the valve at a subsequent opening of the valve.

It is also achieved in this way that only a small residue adheres to the end face, in particular if the delivery is directed downwards.

In combination with the continuous surface, it is further preferred that the continuous surface forms an outwardly curved part of a sphere segment with a considerably larger radius than the diameter of the valve body. This embodiment ensures that only a small drop of substance remains at the center of the end face when the delivery is directed downwards.

In order to obtain a good closing action, it is preferably provided that the free end of the stationary body is cone-shaped, so that the sealing surface of the stationary body forms a ring segment of a conical surface, the inner circumference of the valve body having a corresponding conical surface .

Further advantageous embodiments of the valve assembly according to the first aspect of the invention are described in the claims and the description with reference to the drawing.

The self-closing valve assembly according to the invention can advantageously be used in a delivery pump for pumping a liquid, possibly pasty substance. In particular, the valve assembly is applicable to a pump with a housing which is attached or can be attached to a storage chamber 35 for a stock of the substance, which housing comprises a dispensing channel with at its extreme end a dispensing opening for dispensing the pumped substance, the pump at the '; 7 & 7 -3 dispensing opening is provided with the self-closing valve assembly. The valve assembly then prevents the dehydration, degradation or oxidation of the substance in the delivery channel.

The valve assembly according to the invention is also advantageously applicable to a dispensing container comprising a storage chamber for a stock of a substance, in particular a liquid, possibly pasty substance, as well as a dispensing pump for pumping the substance, preferably a dispensing pump as above described.

The second aspect of the invention relates to a device according to the preamble of claim 16 for dispensing metered portions of different substances, in particular hair dye. Such a device is known from DE 41 13 454.

The known device comprises a frame with a movable magazine therein, which is provided with a plurality of receiving locations, each of which is adapted to receive an exchangeable storage container, which has a storage chamber filled with a substance. In particular, the exchangeable storage containers are filled with hair dye for dyeing hair in a hair salon.

The known device is furthermore provided with drive means for moving the magazine, such that in each case one of the supply containers can be brought to a delivery location of the installation for dispensing substance into a collection container arranged at the delivery location.

This known device has a number of drawbacks that make the device unsuitable for large-scale application in hairdressing salons and the like.

The present invention has for its object to propose various measures which eliminate one or more of the disadvantages of the known device, as will be explained in more detail below.

A disadvantage of the known device is that - despite the measures taken to remove the residues at the dispensing opening 35 - the hair dye in the dispensing channel can dry and cure. As a result, that delivery channel can be completely or partially blocked. The invention provides for this problem to be * ® * 5? 4 7 -4-release with a self-closing valve assembly according to the first aspect of the invention.

Another drawback of the known device resides in the use of storage containers which are arranged to be pressurized or to be delivered to release the hair dye. Namely, when composing a mixture of hair dye a relatively accurate control of the amount of each of the components of the mixture is required. A valve-controlled release under gas or air pressure from the supply chamber makes it difficult to dose, especially since, for example, the viscosity of the hair dye can have a major influence on the outflow with this delivery method. The known device therefore requires a costly accurate weighing device to determine what quantity has been dispensed into the collection container.

The invention has for its object to solve this problem by providing each storage container with an associated operable pump, which is integral with the storage container and is adapted to pump substance out of the storage chamber during operation and to deliver it via a delivery opening at the associated delivery opening, or by providing the magazine of the device at each receiving location with a controllable pump which can be connected to a storage container and which is adapted to pump substance out of the storage chamber upon delivery and to deliver it via a dispensing opening associated with the pump. Preferably, a pump is used that delivers a small amount of the substance at each operation, so that the number of pump operations is representative of the amount of hair dye dispensed.

Also, if essentially a dosage control is possible through the operation of a pump, it is preferred that the device is provided with volume detection means for detecting the volume of the substance present in each of the storage containers. For example, it may be provided that the circumferential wall of the storage container is translucent over at least a longitudinal strip thereof and that the volume detection means comprise an optical sensor which detects the position of the piston of the storage container through the transparent circumferential wall.

it ύ i j «· 4 / -5-

With the known device, all storage containers are identical and the storage containers can be placed at any location in the warehouse. Via optically or electrically readable coding means on the storage containers it is then recorded which storage container is placed at which place in the warehouse.

The invention provides a simpler and less susceptible to malfunctions, in which a storage container is provided on its outside with a key formation, that is to say a molded part with a key function, which key formation is representative of the substance with which the storage container is filled. The magazine is herein provided with a corresponding key formation at a recording location, possibly arranged in an exchangeable part, such that only a supply holder with the correct key formation can be placed at the relevant recording location in the magazine.

The known device is further hardly provided with measures that guarantee the safety of the operator. The invention provides in this field that the drive means of the magazine are inoperative if no collection container is present at the dispensing location. As a result, the delivery of hair dye can only take place if it is guaranteed that the delivered hair dye ends up in the collecting container. In particular because of its oxidizing character, it is undesirable that spilled hair dye must be removed by the hairdresser's salon.

The invention also provides a protection against getting caught in the moving parts of the device by hand or finger (s). This is achieved in that the device has a housing with an opening therein for arranging a collection container at the dispensing location, and in that the collection container has dimensions with respect to that opening such that access by hand or one or more fingers to the interior of the housing is impossible when the collecting container is arranged at the intended location.

Further inventive ideas as well as advantageous embodiments are described in the claims and the 'T7' 7 -6- following description with reference to the drawing. It shows:

FIG. 1 a longitudinal section of a telescopic pump component provided with a self-closing valve assembly according to the first aspect of the invention,

FIG. 2 a holder with integral pump provided with the telescopic pump part of figure 1,

FIG. 3 shows diagrammatically in front view a dispensing device for dispensing metered portions of different substances, in particular hair dye,

FIG. 4 shows the device of figure 3 in side view, and

FIG. 5 shows the device of figure 3 in top view.

Figure 1 shows a telescopic pump part 1, which is provided with a self-closing valve assembly 2.

The pump part 1 is made of suitable plastic material and has a lower cylindrical ring wall 3 with an abutment edge 4 along the outer circumference. Integral with the ring wall 3 is a radial ring wall 5, which forms the transition to an upper cylindrical ring wall 6 of smaller diameter than the lower ring wall 3. At its free end, the upper ring wall 6 is provided with an inwardly protruding edge 7 which defines a circular opening in the pump part 1. The self-closing valve assembly 2 to be described is placed in this opening.

The valve assembly 2 comprises a central stationary body 9 with a free end bounded by a front surface 10 of the stationary body 9 and with a sealing surface 11 near the free end. The sealing surface 11 extends around the circumference of the stationary body 9 and here adjoins the end face 10. The free end of the stationary body 9 is here cone-shaped, so that the sealing surface 11 forms a ring segment of a conical surface.

The valve assembly 2 further comprises an elastic annular valve body 12, which extends around the stationary body 9 and has a sealing surface 13 at its inner circumference, which sealingly abuts the sealing surface 11 of the stationary body 9. The sealing surface 13 has the shape of a ring segment of a conical surface corresponding to the sealing surface 11.

The valve body 12 is fixed at its outer circumference to the pump part 1 in a manner to be described below.

The valve assembly 2 is such that the end face 10 forms a continuous, smooth surface with the outer surface of the surrounding valve body 12 and even with the outer surface of the edge 7.

In the embodiment shown, this continuous surface forms part of an outwardly curved bulb grain with a considerably larger radius than the diameter of the valve body 12.

The stationary body 9 is integral with an insert 15 which is clamped in the ring wall 6. Hereby the valve body 12 is provided on its outer circumference with a thick circumferential rib 16, which is enclosed between the insert 15 and the inwardly projecting edge 7.

The insert 15 is provided with a central axial passage channel 17, which is in line with the more or less pin-shaped body 9, which passage channel 17 connects to a plurality of passage channels 18 formed in the insert 15 from the other side. Transverse webs are then present between said channels 18, whereby the body 9 is integral with the insert 15. In this example, the insert 15 is also made of plastic.

On its end face facing away from the body 9, the insert 15 is provided with an annular groove 19.

The valve body 12 is preferably made of a suitable plastic material, for example based on silicone.

In the presence of sufficient pressure against the inner surface 20 of the valve body 12, that valve body 12 will deform and a gap will arise between the sealing surfaces 11, 13, so that the substance can be dispensed to the outside. When the pressure of the substance drops 35, the elasticity of the material of the valve body 12 causes the valve to close.

Figure 2 schematically shows in longitudinal section a holder 30 with an integral pump 31, which is provided with the telescopic pump part 1 of figure 1.

The pump part 1 is here telescopically guided in an outer ring wall 32 of the housing of the pump 31, which ring wall 32 has an inwardly projecting stop edge 33 near its free end. The edge 33, in conjunction with the edge 4, limits the extreme position of the pump part 1.

The holder 30 furthermore has a storage chamber 35 for the substance, in particular hair dye, which is bounded by a circumferential wall 36, a fixedly connected sealing wall 37 with an opening 38 therein, and opposite the fixed sealing wall 37 a sealing with respect to the circumferential wall 36 slidable piston 39.

The peripheral wall 36 and the fixed closing wall 37 are integral with the ring wall 32 made of a suitable plastic material in an injection molding process.

A suction valve 40 is accommodated in the opening 38, which valve 40 closes in a known manner in the direction of the storage chamber 35.

Between the telescopically movable pump part 1 and the fixed closing wall 37 an elastic bellows 41 is arranged, which bellows 41 forms an internally variable pumping chamber 42. This pump chamber 42 connects via the valve 40 to the storage chamber 35 and is in open connection with the passage channels 17, 18, which form the delivery channel of the pump 31.

The operation of the pump with bellows 41 is known from the prior art and does not need to be further explained here. During operation it is sufficient to press on the ring wall 5 in order to release substance from the holder 30. When resetting the pump part 1, substance is sucked in from the storage chamber 35. The piston 39 then moves towards the fixed closing wall 37.

The presence of the valve stem assembly 2 at the extreme end of the delivery channel 17, 18 prevents the entry of air into that channel and thereby degradation, dehydration or oxidation of the substance. As mentioned, this is very advantageous with hair dye, for example.

The pump 31 has a simple construction, which makes it acceptable that the holder 30 is used as a disposable holder.

In a variant, it can be provided that the pump 31 is detachable from the part of the holder 30 with the storage chamber 30.

On the basis of Figures 3, 4 and 5, a dispensing device 100 for dispensing metered portions 10 of different substances, in particular hair dye, is explained below.

The device 100 shown is particularly intended to be placed in a hair salon.

The device 100 comprises a frame with a bottom plate 101, four posts 102 and a cross 103, which connects the upper ends of the posts 102. A vertical axis 104 is present between the bottom plate 101 and the center of the cross 103.

A rotatable magazine 110 with a lower circular carrier 111 and an upper carrier 112 is arranged around the shaft 104.

In both carriers 111, 112, two concentric ring arrangements are provided along the outer circumference for several receiving locations, each for receiving an exchangeable storage container 30 with integral pump 31. The receiving locations of the two ring arrangements are slightly offset relative to each other in the circumferential direction.

The holder 30 with pump 31 has been explained in detail above. Here, the holders 30 with the pump 31 protrude downwards into the magazine 110, such that the fixed part 30 of the holder 30 is held stationary with respect to the magazine 100 and the pump part 1 is movable up and down.

In order to be able to place and take out the holders 30, the housing of the device 100 (not shown) can be provided with an opening which can be closed by a cover or the like at the top.

The lower carrier 111 is provided around its periphery with a gear ring 115 which engages a gear wheel 116.

"k / - j 'A Λ -10-

The gear wheel 116 is provided on a shaft 118 driven by an electric motor 117, preferably a stepper motor.

The motor 117 is coupled to control means (not shown) such that in each case one of the supply containers 30 can be brought to a delivery location 120 of the device 100 for dispensing a portion of hair dye into a collection container 121 arranged at the delivery location.

Furthermore, in the center of the magazine 110 there are four receiving locations 119 for larger containers, for example with hydrogen peroxide.

The device 100 is provided with pump operating means 130 which are adapted to operate the pump 31 from a holder 30 positioned at the dispensing location by pressing the pump part 1 thereof upwards a desired number of times.

In this example, the pump operating means 130 comprise an arm 131 which is pivotally attached to the frame about a horizontal axis 132. The free and up and down movable end of the arm 131 extends below the dispensing location 120 of the holders 30 in the inner and outer ring of the magazine 110. At that end, the arm 131 is provided with an engaging member 133 with a central opening such that the ring wall 6 of the holder 30 can protrude into that opening while the engaging member 133 rests against the ring wall 5 of the pump part 1 in diametrically opposite positions.

When the engaging member 133 is pivoted upward, a portion of hair dye comes out of the dispensing opening in the collecting container 121, as is indicated in Figure 3.

Suitable hinge means can be provided for pivoting the arm 131, for example a stepper motor 30 with an eccentric cam, which engages the arm 131 at a distance from the pivot axis 132.

In a variant not shown, each pump 31 cannot be coupled integrally to the storage part of the container, but can be releasably coupled thereto. The stock part could then, for example, also be formed by a bag 35 or the like. The pumps 31 are then preferably releasably arranged in the magazine 110, so that the pumps 31 can be removed for cleaning and the like.

-11- I

The release of hair dye from the single operation of the pump 31 appears to be highly constant and hardly to vary under the influence of, for example, temperature changes.

Therefore, the number of times a pump 31 is operated is a good indication of the portion dispensed. The control means therefore preferably comprise counting means for counting the number of times that a pump 31 is operated.

Above the delivery location 120 of the holders 30 in the inner and outer ring arrangement, there is in each case a sensor 140 for detecting the volume of the hair dye present in each of the holders 30.

The sensors 140 are each adapted to detect the position of the piston 39 of the holder 30. The sensors 140 may, for example, be of the type with optical triangulation or ultrasonic.

In a variant, the circumferential wall 38 of the holder 30 is translucent at least over a longitudinal strip thereof and the volume detection means comprise an optical sensor which detect the position of the piston 39 through the translucent circumferential wall.

In a variant, the bellows 41 are missing from the holders 30 and the pump part 1 is then no longer a pump part, but fixed and integral with the wall 32. The device 100 can be provided above the delivery location with a pressure means to lower the piston 39 downwards. to deliver hair dye. The pressure medium can be mechanical but can also work with gas or air pressure.

In another variant, not shown, each holder 30 is provided on its outside with a key formation, which key formation is representative of the hair dye with which the supply container is filled. Furthermore, at a recording location, the magazine 110 is provided with corresponding key formation, optionally arranged in an exchangeable part, such that only a holder 30 with the correct key formation can be placed at the relevant recording location.

Preferably, it is provided here that each container 30 is provided with the relevant key formation when filling the storage chamber 35, for example by arranging an annular body provided with the key formation around the circumference of the storage container.

The device 100 is preferably used in combination with separate collection containers 121, wherein detection means are then provided for detecting the presence of a collection container 121 at the dispensing location 120.

By applying such a detection it can be achieved, for example, that the drive motor 117 of the magazine 110, and possibly also the pump operating means, is ineffective if no collection container 121 is present at the dispensing location.

Hereby is prevented that hair dye can be delivered, which then contaminates the device 100.

The housing of the device 100 has an opening on the side, which makes it possible to set up a collecting container 121 at the dispensing location 120. It is preferred here that the collecting container 121 has such dimensions with respect to that opening that access by hand or one or more fingers 20 to the interior of the housing is impossible.

The detection of the collecting container 121 can be effected, for example, in that each collecting container 121 is provided with a key formation, for example a protruding lip, and the device 100 is provided with a corresponding key formation, for example a mortise slot for the lip, wherein the device 100 is further provided of detection means that detect whether the key formation of the collection container corresponds to the key formation of the device.

In a variant (not shown), stirring means are provided for stirring / mixing the portions of hair dye dispensed in the collecting container 121. A possible embodiment can be that the stirring means comprise one or more stirring members, which are provided at each collection container 121, and the device is provided with drive means for driving the stirring members.

The device 100 is preferably provided with an electronic memory, in which several recipes for mixture to be produced from the substances to be manufactured can be stored. The device 100 can then be provided with a keyboard or other input means with which the desired recipe is selected.

Preferably, the control means of the device 100 is further provided with a portable control unit, and wherein wireless transmission means are provided for data transfer between the portable control unit and the control means accommodated in the device. The hairdresser can then stay with the customer to choose the desired recipe and only needs to take the collecting container 121 out of the device 100 after the mixture has been made.

In an advantageous embodiment the portable control unit is provided with read-out means for reading information stored on a loose carrier to be offered to the control device. For example, each customer has a magnetic or chip card in which, for example, the (last used) recipe for that customer is recorded.

To ensure that the hairdresser can make a certain hair dye if desired, it can be provided that an additional magazine is present, for example a special cupboard, for storing storage containers 30, wherein the additional warehouse is provided with storage control means for storing keep track of the stock of stock holders in the warehouse. The stock control means are preferably adapted to automatically forward an order from stock holders to a supplier.

It will be clear that the described holder 30 and device 100 are very suitable for use in a hair salon 30 in making hair dye mixtures. Instead of hair dye it is of course also possible to envisage applications with other substances, such as cosmetics, cream soap, etc.
