Description

DETAILED DESCRIPTION OF THE INVENTION

The invention relates to a dispensing container for a mixture having a high or low viscosity, for example a pasty or liquid mixture as defined in the preamble of claim 1.

From EP 0 755 721 A2 a proportional dispensing container is known in which the mixing ratio of two pasty or liquid fluid components can be continuously adjusted. A similar proportional dispensing container is a dispensing container for a sunscreen lotion, for example, in which two sunscreen lotions having sun protection factors of 1 and 25 are mixed and the sun protection factor can be continuously adjusted in the range of 1 to 25. Has been used as useful. This new proportional dispensing container allows the user to select the sun protection factor according to the degree of sun exposure and skin conditioning, without having to carry several lotion containers with different sun protection factors. It is very convenient in a good point.

According to the solution proposed in EP 0 755 721 A2, a proportional dispenser is associated with a replaceable cartridge containing a sunscreen lotion of a different type (eg having a sun protection factor of 1 or 25). Equipped with two pumps. These pumps are actuated by two eccentric levers mounted on the housing of the proportional dispenser and operatively connected to a pump head or nozzle head which is moved by the consumer. The adjustment of the sun protection factor is effected with the aid of a rotary knob mounted on the housing and acting via adjusting means, so that the relative position of the pump with respect to the fulcrum of the eccentric lever can be adjusted. This change in the distance of the eccentric lever from the fulcrum allows the stroke of each pump to be adjustable in the range between zero (no stroke) and the maximum stroke. This adjusting means operates here in such a way that the strokes of the two pumps can each be adjusted in opposite directions.

[0004] The above-described device is perceived to be disadvantageous in that its cost is high due to its complex structure and difficulty in manufacturing. Further, since the pump and the cartridge are sequentially arranged, the structure is longer than that of a conventional sunscreen lotion container.

[0005] DE 198 18 434.4 discloses a proportional dispensing container as shown in the accompanying FIG.

According to FIG. 2, this proportional dispensing container comprises a nozzle head 2 housed axially displaceable in a housing 4. An outlet nozzle 6 is formed in this nozzle head, and when the nozzle head 2 is moved in the direction F (arrow in FIG. 2), a high-viscosity or low-viscosity mixture is discharged through the nozzle. Here, the proportional dispensing container is intended, for example, to distribute and mix a sunscreen lotion, such that the mixing covers a range from a minimum sun protection factor of 1 to a maximum sun protection factor or 25. Done. To adjust the mixing, a rotary knob 8 operatively connected to the adjusting means is mounted on the housing 4. Inside the housing 4, two cartridges 10a and 10b having the same structure are accommodated as shown in FIG. One cartridge contains a sun protection factor of 1 sun protection lotion and the other cartridge contains a maximum configurable sun protection factor, for example 25 sun protection lotions.

The removal of the contents from these two cartridges takes place in the respective pumps 12 a
And 12b. The suction port 14 of the pump communicates with the outlet of the cartridge through which sunscreen lotion is drawn from the cartridge. The pump is a reciprocating pump whose pump plunger 16 is guided in a pump housing 18 and is axially displaceable. The pump plunger 16 is moved by respective eccentric levers 20 mounted on the pump housing 4 by rotary mounting means 22. The rotation of these two eccentric levers 20 for distributing the sunscreen lotion is effected by the nozzle head 2 which is displaceable in the F direction and which acts on the two pivot levers via a push button 24. The lower surface of the eccentric lever 20 in FIG. 2 contacts the pump head 26, which is connected to the pump plunger 16 via which the movement of the eccentric lever 20 is transmitted to the pump plunger 16. A pressure port 28 is formed within the pump head 26 of each pump 12 through which the sunscreen lotion carried by the pump 12 exits. This lotion leaving the pump 12 is conveyed to the mixing means through an elastic conduit not shown here, where the two components are mixed and guided to the nozzle head 2. In some cases, a separate mixing means, such as a mixing chamber, may be omitted and the pump 12 or its pressure port 28, respectively, may be connected directly to the nozzle head by a Y-shaped member or the like.

The adjustment of the mixing ratio is performed by adjusting the stroke of the pump plunger. The pump 12 is mounted rotatably, so that the lever length of the eccentric lever 20 acting on the pump 12 is adjustable. The length of this lever is determined by the distance between the rotary mounting means 22 and the position of engagement of the pump head 26 on the eccentric lever 20. The adjustment is effected by a cam disc 30 connected to the rotary knob 8, the cam guide of which guides the two cam follower pins of the guide bracket 32. The latter surrounds the two pumps 12a and 12b and ensures that they rotate simultaneously. Rotation of the pump 12 is enabled by a ball joint 34.

When operating the proportional removal container 1, the two filled cartridges are housed in the housing 4. The predetermined sun protection factor is adjusted by the consumer with the aid of the distribution knob 8 so that the cam disc 30 rotates and the guide bracket 32 is connected to the cam disc via cam follower pins which engage the cam guide. Displaces laterally (as viewed in FIG. 2) depending on the position. This movement of the guide bracket 32 is transmitted to the pumps 12a, 12b, the latter correspondingly rotating about its ball joint 34. In the position shown in FIG. 2, the two pumps are located at both ends of the pivot range, and the pump 12a is connected to its pump head and the rotary mounting means 22.
Is the maximum distance, while the axis of the other pump 12b is
Intersects with 2. In other words, when the two eccentric levers 20 operate, the pump 1
The pump plunger 16 of 2a is at maximum stroke (as seen in FIG. 2), but the pump plunger 16 of the second pump 12b does not move at all. Thus, the sunscreen lotion is pushed out of the cartridge 12a only, and the sun protection factor is adjusted to one or vice versa. By turning the rotary knob 8 in the opposite direction, the two pumps occupy their respective vertical positions, the effect lines of the two pump plungers 16 are at the same distance from the associated rotary mounting means 22 and both pumps The same stroke results. In this case, the mixing ratio is adjusted to 1: 1. When the rotary knob 8 is further rotated, the other extreme state is adjusted, in which only the components in the cartridge 10b are removed.

[0010] For further details of this proportional dispensing container, see DE 194 18 434.4. This disclosure is fully incorporated herein by reference.

[0011] Proportional discharge containers according to DE 194 18 434.4 have proven to be reliable under practical conditions. However, this dispensing container suffers from the disadvantage that the adjusting mechanism for adjusting the mixing ratio has a relatively complicated structure. Furthermore, the cost is high since both cartridges must be pivotally mounted on the ball joint.

[0012] In contrast, the invention is based on the object of providing a proportionally dispensing container having an adjusting mechanism for each pump which is structurally simple and safe to operate.

This object is achieved by the features of claim 1.

According to the present invention, there is provided a proportionally dispensing container for a mixture of high and low viscosity comprising a housing fitted with at least two adjustable pumps, preferably a reciprocating pump. Thus, the displacement of the pump is adjustable with the aid of adjusting means, whereby the respective components are carried from the cartridge to the mixing means connected to the nozzle outlet. According to the invention, each cartridge has a recess on the front side on the pump side, into which at least a part of the foot of the pump fits.

By providing a recess in the cartridge of the proportionally dispensing container and fitting the foot of the pump with the pump inlet therein, the cartridge and the pump substantially overlap in the axial direction, and the conventional device Although the structural length is greatly reduced compared to,
This does not limit the capacity of the cartridge. Preferably, a reciprocating pump is used. The structural space can be further reduced by mounting the pump in a housing receiving portion having a shape and dimensions adapted to the recess of the cartridge so that the front surface associated with that of the cartridge is in surface contact with the receiving portion of the housing. Can be.

Advantageously, the pump bearing is in the form of a ball joint. The cartridge can be emptied particularly easily if a suction opening is formed in the recess of the receiving part of the housing and opens to the cartridge outlet formed at the deepest point of the recess of the cartridge.

In a preferred embodiment, a cartridge, such as a container for removing toothpaste, has an axially displaceable piston bottom that displaces the interior of the cartridge depending on the filling condition. The piston bottom has a projection that substantially fits into the aforementioned recess, so that when the piston bottom is in the end position, i.e. when the cartridge is completely empty, the piston bottom makes surface contact with said recess.

Here, it is particularly desirable that a vent is formed at the apex of the convex portion at the bottom of the piston, through which ventilation is performed when the cartridge is filled, so that the cartridge is completely filled.

In the proportional dispenser of the invention according to the first embodiment, the pump is moved via an eccentric lever, which is preferably pivoted with the aid of a nozzle head. In the prior art, the eccentric lever acts directly on the pump plunger, and depending on the relative position of the pump to the eccentric lever, a lateral force may be generated, causing the piston to tilt and become immobile. To eliminate this drawback, the pump
It has been proposed to apply an eccentric lever to the piston via a pump head, which is guided sliding in the housing, so that no lateral forces act on the piston.

This lateral force acting on the pump plunger can be further reduced if the radially concave end of the pump plunger fits into the drive part of the pump head. To prevent tilting of the pump head, the pump head has a spherical contact surface for an associated eccentric lever. To synchronize the two pumps, in this embodiment they are connected to each other by guide brackets. In another example, the pump housing may have a corresponding connecting member, so that a direct connection of the pump housing can be made without additional components.

If a guide bracket is used to connect the pump housings, the guide bracket preferably surrounds the two pump housings. The latter carry pegs that fit into corresponding receivers of the guide bracket.

The guide bracket, or alternatively the pump housing, comprises a cam follower pin which is guided in a cam guide of a cam disc which can be adjusted with the aid of a rotary knob on the housing of the proportional dispenser. . If the cam means is divided into two helical cam sections on which the guide bracket or the cam follower pins of the two pump housings are guided, the stroke of the pump is adjustable over a wide range.

In order to prevent malfunction of the proportional dispensing container, the end position can be adjusted with the aid of a rotary knob, in which axial displacement of the nozzle head is not possible.

In a particularly advantageous embodiment, the nozzle head acts on the two eccentric levers via a push button, wherein the push button is formed with mixing means, which is provided at the outlet of the pump head. And is open to the nozzle of the nozzle head. If a static mixer is used as the mixing means, the number of moving parts can be reduced.

If at least part of the cartridge is made of a transparent material and the housing of the proportional dispenser is provided with a window, the filling state of the proportional dispenser can be read in a simple manner.

The insertion of the cartridge into the proportional removal container is preferably performed with the aid of an operating part provided on the bottom lid of the cartridge. Since the shape and dimensions of the operating portion substantially match the shape of the convex portion at the bottom of the piston, there is no increase in the axial length, and comfortable operation is possible.

The connection of the two pump housings, the shape of the cartridge, the intermediate arrangement of the pump head between the eccentric lever and the pump plunger constitutes a separate invention, if taken on its own, to protect the rights. It should be pointed out here that it is possible to file another application. The present invention is not limited to the distribution of the paste-like substance, and a low-viscosity substance such as paint or liquid can be mixed. If desired, more than two pumps can be integrated into the housing to mix more than two components.

From the following description with reference to the drawings, further detailed configurations, embodiments and advantages will be apparent.

FIGS. 1 to 3 show an overall view of a first embodiment of a proportionally dispensing container 1. According to FIG. 1, this proportional dispensing container comprises a nozzle head 2 which is axially displaceably received inside a housing 4. The nozzle head 2 has an outlet nozzle 6 from which a mixture having a high viscosity or a low viscosity exits when the nozzle head 2 is operated in the direction F (arrow in FIG. 1). In this embodiment, a proportional dispenser 1 is provided for dispensing and mixing the sunscreen lotion, wherein the mixing is performed to cover a range from a minimum sun protection factor of 0 to a maximum of 25, for example. .

To adjust the mixture, a rotary knob 8 operatively connected to the adjusting means described below.
Are attached to the housing 4. For ease of operation, the rotary knob comprises two gripping recesses 10a and 10b, between which a thin wall 12 is formed, which is designed for the consumer to pinch and turn. To facilitate the adjustment, a scale (not shown) is printed on the housing 4, and a desired sun protection factor can be selected by aligning the arrow on the thin wall 12 with a desired scale.

According to FIG. 2, two cartridges 14 a and 14 b are received in the interior of the housing 4, but since they have the same structure, henceforth only the reference 14
Will be shown. One cartridge 14 contains a sunscreen lotion with a sun protection factor of 0 (eg, body lotion without sun protection factor) and the other cartridge has a maximum adjustable sun protection factor, eg, 25. Contains sunscreen lotion.

To see the filling, the cartridge 14 described in more detail below is made of a transparent material and the housing is provided with a window 16 along the longitudinal axis of the cartridge,
The filling status can be checked at any time. A more detailed structure will be described below with reference to a sectional view.

FIG. 2 shows a cross section of the proportional take-out container 1 shown in FIG. According to this,
The removal from the two cartridges 14 is performed by respective pumps 18a and 18b having the same structure, but the following description will be limited to one pump. The suction port 20 of this pump communicates with the outlet 22 of the cartridge. The sunscreen lotion is sucked out of the cartridge 14 therethrough. Pump 1
8 is a reciprocating pump, the pump plunger 24 of which is a pump housing 26.
Are guided in such a way that they can be displaced in the axial direction. The pump plungers 24 are actuated by eccentric levers 28 each mounted on the pump housing 4 via rotary mounting means 30.

The two eccentric levers 28 for distributing the sunscreen lotion are pivoted by the nozzle head 2 displaceable in the F direction and acting on the two pivot levers via the push buttons 32. Engaging projections 34 are formed on mutually facing free end portions of the eccentric lever 28 and engage with the engaging recesses 36 of the push button 32 to positively connect the eccentric lever 28 and the push button 32. . 2 contacts a pump head 38 connected to the pump plunger 24, whereby the movement of the eccentric lever 28 is transmitted to the pump plunger 24. A pressure port 40 is formed inside the pump head 38 of each pump 18, through which the pump 1
The ingredients of the sunscreen lotion carried by 8 come out. This lotion coming out of the pump 18 is supplied to the mixing means 42 (by an elastic conduit not shown here).
3), where the two components are mixed and the nozzle head 2
It is led to.

By adjusting the stroke of the pump plunger, the mixing ratio is adjusted. In the illustrated embodiment, the pump 18 is pivotally mounted so that the lever length of the eccentric lever 28 acting on the pump 18 is adjusted. The lever length is determined by the distance between the rotary mounting means 30 and the position of the eccentric lever 28 where the pump head 38 is engaged. In the embodiment shown, this adjustment is made by a cam disk 44 connected to the rotary knob 8, the cam guide 46 of the cam disk guiding the two cam follower pins 48, 49 of the guide bracket 50. The guide bracket surrounds the two pumps 18a and 18b, thereby ensuring that they rotate simultaneously. The rotation of the pump 18 is enabled by a ball 52 guided in a joint socket 54 of the housing 4. The ball joint, including ball 52 and joint socket 54, allows for mounting and guiding of pump 18 with any desired degree of freedom with very little friction.

A more detailed technical configuration of the pump 18 will be described with reference to FIG. 4 showing an enlarged detailed view of the pump 18 a in FIG.

As shown in FIG. 4, the housing 4 has an intermediate bottom 56 in which a bayonet-type receiving portion 58 for fixing the cartridge 14 is formed. In addition, the intermediate bottom 56 comprises a receptacle-shaped housing receiving portion 60 recessed toward the pump 18 in FIG. 4, in which the joint socket 54 is formed. Inside the recess of the receiving part 60 of the housing, a projection 62 projecting downward like a nozzle (as viewed in FIG. 4) is formed to provide a suction opening 64. Joint socket 54 surrounds ball 52, which has a central hole 66 extending therethrough. This center hole is open on the one hand to the suction opening 64 of the receiving part 60 of the housing and on the other hand to the suction port 20 of the pump 18. To secure the ball 52, the pump housing 26 has a projection which is inserted into the central hole 66 of the ball and is press-fitted or connected to the ball 52. In the area where the suction port 20 is open to the cylindrical space 68 of the pump housing 26, a suction valve 70 shown by a dotted line is formed, and the fluid flows from the cartridge 14 to the cylindrical space 68. It does not flow in the opposite direction. This suction valve 70 is preferably biased by a spring in the closing direction. The pump plunger 24 is in the form of a hollow piston and its guide collar 72 is
It is in contact with the inner peripheral wall of the housing 26. A projection with a step extends in the radial direction from the guide collar 72 and enters the receiving hole of the pump head 38. The hole covers the projection 74 in a bell shape. The upper surface of the protrusion 74 shown in FIG. 4 contacts the ring-shaped shoulder 76 of the pump head 40, and the axial displacement of the pump head 38 is transmitted to the pump plunger 24.

At the bottom of the bell-shaped pump head 38, a pressure port 40 extending obliquely downward as viewed in FIG. 4 is opened, and a pressure valve (not shown) is arranged therein, and the sunscreen lotion is provided with a cylindrical shape. The backflow is prevented from flowing into the space 68. At the end of the pump head 38 projecting from the pump housing 26, a spherically projecting contact surface 76 is provided, which defines a defined contact surface limit for the associated eccentric lever 28. The inclination of the pressure port 40 and the shape and dimensions of the eccentric lever 28 are determined by the pump 1
It is designed so that these components will not collide with each other over the entire range of eight revolutions. In addition, the pump head 38 comprises a guide projection (perpendicular to the plane of the drawing in FIG. 4) slidably received in a corresponding guide receiving part (not shown) of the pump housing 26, whereby the pump head 38 axial guides are possible. Thanks to the eccentric lever 28, a lateral force component always acts on the pump head 38, which lateral force component is received in the guide means of the pump housing 26, and substantially only the pump plunger 24 is in the axial direction. This has proven to be particularly advantageous because it is not subjected to force and therefore does not get stuck.

As described above, two pegs diametrically disposed perpendicular to the plane of the drawing and fitted in corresponding receiving portions of the guide bracket 50 are formed on the outer peripheral edge of the pump housing 26. Have been. This guide bracket is shown in FIG. According to this, the latter comprises a continuous peripheral rim 78 and the pump housing 2
A receiving portion 80 (shown by a dotted line) for a peg (not shown) in 6 is provided. Two wedge surfaces 82 and 84 (see FIG. 4) are formed on the small surface of this peripheral rim 78 and serve as stops for stopping the pump housing 26 at its end positions, defining a range of rotation. .

Furthermore, the peripheral rim 78 carries two cam follower pins 48, 49, whereby the guide bracket 50 is guided by the cam disc 44. This cam disk 44
Are shown in FIGS. 6 and 7. On the main surface of the cam disk shown in FIG. 6, two spiral cam guide portions 46, 47 are shown, on which cam follower pins 48, 49 are guided, respectively. The construction of the two-part cam guides 46 and 47 is necessary to maximize the width of the adjustable range of the pump stroke, with the smallest possible rotational range of the cam disc. The cam guide 46 is provided with a stop 82, which limits the pivot end position of the pump. The cam guide portions 46, 4 selected in FIG.
In the arrangement 7, only one of the cam follower pins 48, 49 is guided by the cam 46 or 47, respectively, in a certain rotation range. In principle, it is also possible to employ other dimensions, shapes or transfer means which allow for precise adjustment of the cam disc 44 with minimal action movement. As can be seen from FIG. 7, which shows a side view of the cam disk 44, the latter has, on the main surface opposite to the cam guides 46, 47, a center bearing pin 84 and a driver 86 arranged in a staggered manner with respect to the center bearing pin 84. , Whereby the cam disk 44 is connected to the rotary knob 8 and rotates with it as a unit. The cam disk 84 is mounted on the intermediate bottom 56 of the housing 4 by bearing pins 84.

As explained earlier, the two pivoting levers 28 are actuated via push buttons 32 which are moved by the nozzle head 2. In the representation according to FIGS. 2 and 3, the nozzle head 2 is in its end position, that is, in the position pushed into the housing 4. This end position is delimited by a stop shoulder which in operation acts as a stop for the nozzle head 2. The guidance of the nozzle head 2 is performed with the aid of a guide collar 90 of the housing 4. The push button 32 is seen from its small surface in FIG. 2, in a side view in FIG. 3, in a top view in FIG. 8, and in a bottom view in FIG. 9 (in relation to FIG. 3). Indicated by According to this, the push button 32 has a central guide sleeve 92 into which the guide pin 94 of the nozzle head 2 is fitted.

According to FIGS. 8 and 9, the components 92 and 94 are formed to have a rectangular cross section. The guide sleeve 92 carries a movable member 96 extending downward in a mushroom shape surrounding the eccentric lever 28 and the engagement recess 36. Referring to FIGS. 8, 9 and 3, beside the guide sleeve 92, two components 98 and 100 of the mixing means 42 are formed, which are resilient conduits for the pumps 18a or 1a.
8b, respectively. According to FIGS. 8 and 9, these two components 98, 100 are connected to a common mixing conduit 102, which opens into a horizontally extending mixing passage 106. Here, the static mixer 104 is arranged as an insert. This static mixer 104 has the configuration shown in FIG.
Are shown separately. According to this, the latter is composed of a plurality of helical portions 105a, 105b, 105c... Sequentially arranged in the axial direction, whereby the two components entering the mixing passage 102 are mixed well. The supply pressure of the pumps 18a and 18b must be sufficient to move the components through the static mixer 104.

The outlet from the mixing passage 102 is connected to the nozzle outlet 6. The two cartridges 14a and 14b are housed in the lower part of the housing 4 and are inserted into the intermediate bottom 56 of the housing 4 by means of a bayonet joint. As can be seen particularly from FIGS. 2 and 3, the pump-side surface of each cartridge 14 is provided with a recess 108, the shape and dimensions of which are adapted to substantially fit into the receiving portion 60 of the bell-shaped housing. When the cartridge 14 is inserted, the recess 108 is inserted into the receiving portion 6 of the housing.
It extends substantially parallel to or in contact with a portion of the cartridge 0, thereby also centering the cartridge 14.

An outlet 22 of the cartridge is formed in the recess of the recess 108, and the outlet 22
10 if closed by other closing means and the cartridge 14 is inserted,
The housing is pierced by a projection 62 of a receiving portion 60. Inside the cartridge, an axially displaceable piston bottom 111 is received, and its bottom surface is configured to form a convex 112. The shape and dimensions of the piston 111 are the shape of the concave 108 and the shape of the receiving portion 60 of the housing. It corresponds to the dimensions. A vent 114 is provided at the top of the protrusion 114.
Is formed, and is closed to the surrounding environment when the cartridge 14 is in the filled state. This vent 114 is opened during filling to ensure that no air is trapped in the cartridge and complete filling. Due to the vacuum created in the cartridge 14 with the aid of the pump 18, the bottom 111 of the piston, depending on the filling state shown in FIG. 3, rises up to its final position shown on the right side of FIG. Moves, where the recess 108 of the cartridge 14 fits into the protrusion 112 of the bottom 111 of the piston. Because of the surface contact, the cartridge 14 can be completely emptied. Since this state is known through the window 16, the cartridge 14 can be replaced in a timely manner.

In order to avoid breakage of the bottom 111 of the piston, the lower end of the cartridge 14 is closed by a lid 116 of the cartridge, as shown in FIG. Surrounds. Cartridge 1
If the cartridge lid 116 is provided with a retractable operating portion 118 that can be gripped by the consumer to secure the 4, i.e., to insert it into the bayonet receptacle 58, screw the cartridge 14 into place. Becomes easier. If the lid 116 of the cartridge is sealed, the vent hole 114 need not be closed.

When operating the proportional dispensing container 1, the two filled cartridges are housed inside the housing 4 so that the bottom 111 of the piston occupies the lower position shown in FIG. When the consumer rotates the cam disc 44 with the help of the distribution knob 8, the cam follower pins 48, 49 engaged with the cam guide 46 cause the guide bracket 50 to move laterally (depending on the position of the cam disc 44). (See Figure 2)
And adjust the sun protection factor to a predetermined value. Guide bracket 5
This action movement of zero is transmitted to the pumps 18a and 18b, the latter correspondingly pivoting around the respective ball joints 52, 54. In the position shown in FIG. 2, the two pumps are located at the ends of the pivot range, the pump head of the pump 18b is at a maximum distance from the rotary mounting means 30, and the axis of the other pump 18a is the rotary mounting means. Crosses 30. In other words, when the two eccentric levers 28 operate,
The pump plunger 24 of the pump 18b moves at the maximum stroke (as viewed in FIG. 2) and the pump plunger 24 of the second pump 18a does not make any stroke. Therefore, the sunscreen lotion is removed from the cartridge 10b only, and the sun protection factor is adjusted to zero or, conversely, to its maximum value. Rotation knob 18
Are rotated in reverse, the two pumps occupy their respective vertical positions (FIG. 2) and the effect lines of both pump plungers 24 are associated with their respective rotary mounting means 30.
And both pumps move on the same stroke. In this case, the mixing ratio is 1: 1
Is set. When the rotary knob 8 is further rotated, the adjustment is at the other extreme,
There, only the components in the cartridge 14a are taken out.

The components coming out of the pressure port 40 of the pump head 38 by the operation of the nozzle head 2 are supplied to the mixing means 42 through the components 98 and 100, and
Within, which results in a formulation with the highest fineness. Then, the mixture is discharged through the horizontal hole 106 and the nozzle outlet 6. When the nozzle head is released, it returns to the home position by a spring effect and the piston 24
The springs return to their respective upper end positions by the biasing of a spring or other appropriate reset mechanism. The proportional dispenser can now correspond to the next dispensing stroke at any time.

[0048] The cartridges 14a and 14b are configured to be refillable, and they are recycled in the form of deposit cartridges. This can significantly reduce packaging costs as compared to conventional sunscreen lotion containers configured as disposable packages. The proportionally dispensing container of the invention with such a pump mechanism remains at the consumer's disposal. This recycling should be understood as an option, and of course, the cartridge 14 can be used as a one-time use product. In order to increase the safety of operation, the pump mechanism can occupy the locked position by turning the rotary knob 8 to an end position where the nozzle head 2 cannot operate.

In the embodiment described above, the two pumps 18 a and 18 b are connected by the guide bracket 50. FIG. 11 shows a simplified embodiment in which the two pump housings 26 have engagement sections 120 and 122, whereby
The pump housings 26 are positively connected to each other. Engagement section 1
As the 22 bearing pins 124 are guided in the receiving holes 126 of the arcuate engagement section 120, both engagement sections 120 and 122 allow the two pump housings 26 to rotate relative to each other. In this case, the cam follower pins 48, 49, etc. must be formed directly on the pump housing 26.

In an example in which the above-described embodiment is modified, it is possible to use a linear drive unit having a gear transmission mechanism and other guide members instead of the cam disk 44. The proportional dispensing container 1 is substantially manufactured by injection molding and is intended to completely recycle the product. To facilitate reading of the filling state, the cartridge 1
Numeral 4 is made of a transparent material such as PMMA, and the bottom of the piston is colored so that the filling state can be read at a glance.

In the above example, the two components were mixed together. Of course, the principles of the present invention are also applicable to mixing more components, where one pump mechanism is associated with each component. This proportional dispensing container can be used to mix paint, mix adhesive,
Alternatively, it can be used for other substances such as a mixture of cosmetics.

In summary, a proportionally dispensing container for mixing a plurality of components in each cartridge has been described. One pump is associated with each cartridge, and the feet of the pump fit into the recesses of the cartridge to minimize the axial length of the proportionally dispensing container.
