DE10331703A1 - Device for portioned and residue less extraction of dispensable liquid material from container has in middle of base of container's sealing cap a guiding and delivery tube with piston at one end and connection to control element at other - Google Patents

Abstract

The device for the portioned and residue less extraction of dispensable liquid material from a container has in the middle of the base of the container's sealing cap (1) a guiding and delivery tube (3) with a withdrawal passage (2) and which is fluid tight but movable and failsafe. The cap end of the tube is formed as a piston (4), and the other outwards protruding end (7) is connected to a connecting element (10) which is a component part of a control element (8). Each movement of the control element effects a movement of the tube and therefore an axial movement of the piston in the direction of the base of the sealing cap. An independent claim is included for a method for the portioned extraction of dispensable material from the aforesaid device.

Description

Technical area:

The The invention relates to a metering and dispensing residue removal device to a portioned and complete removal also very differentiated Quantities of a liquid Donation good, as well as a method for its removal from a any compliant or non-compliant dispensing container according to claim 1 and claims 17 and 18.

State of the art:

Out the prior art are several dosing systems, for example Measuring cups, dosing pumps, etc., known for dosing household cleaners, Dishwashing liquid, All-purpose cleaners, medicine, etc. are used because their exact dosage on the one hand, as in medicine, it is not important for its effect on the other hand with other products by means of environmental protection laws is required so as not to unnecessarily burden the environment and subsequently Saves costs. Also a complete, as far as possible going emptying a container is only insufficiently guaranteed with these systems. In the current dosing systems is neither one, especially necessary for toxic substances, precise Dosage of a donated good nor its complete removal from one container For example, the measuring marks on a measuring cup are always guaranteed after its multiple application are often difficult to recognize since the measuring cup is contaminated with the donation over time. Furthermore, the user can easily with the often poisonous donation in touch come, for example, when dumping what to avoid right now is. Also still is after dosing systems and devices sought, on the one hand, in particular a duly accurate dosage of toxic and medicinal substances guarantee the desired effect of On the other hand, the best possible emptying should be ensured a container by means this possible be the more poisonous the donation, the more urgent this request, and not a fulfillment this one with additional financial charges (environmental protection laws).

For this Dosing pumps have been developed that consist of several parts, - up to 10 -, exist and expensive in their production and material are.

• – ihre Unzuverlässigkeit wenn die dosierte Menge nicht auf einmal entnommen wird,
• – kein Einsetzen bei Produkten die direkt vor der Dosierung geschüttelt werden müssen da nach einem Loslassen des Druckkopfes einer Dosierpumpe, ihr Messraum sich sofort mit dem Spendengut füllt und in ihm bis zur nächsten Dosierung verbleibt,
• – ihr hoher Preis.

Other disadvantages of these include:

• - their unreliability when the dosed quantity is not taken at once,
• - no insertion on products that need to be shaken just before dosing because after releasing the printhead of a dosing pump, its measuring space immediately fills with the donation and remains in it until the next dose,
• - her high price.

Farther is to be evaluated as a disadvantage that from such a metering pump only a given amount of a donation is to be found, what their application to a product of that once for example 5 ml and once 50 ml should be dosed, excluding none Users can expect that in this example 10 times that Dosing system actuated, these processes counts, and so dosed.

Another The disadvantage is that in case of premature termination of a dosing process, is the amount of a donated product dosed until then difficult, Immediately and precisely determined.

In contrast, lies The present invention is based on the object, such a precise metering device to propose, in the above-mentioned disadvantages partially or be completely fixed.

Further The object of the invention is by means of one and the same metering device also very different quantities of a donation good, and to dose in one operation. Further task of the present Invention is the user when removing the donation before direct Contact with the item to be donated, with proper use of the dosing system, to protect.

This object is achieved according to the invention in a metering and Spendengutreste-removal device of the type mentioned in that in the bottom of a cap or the like, an axially, reciprocally movable, provided with an emptying channel guide and dispensing tube is sealing, the inside of the cap end facing to a piston is the one during its displacement forms, with the inner wall of a container or a closure cap, a variable but dense measuring space in its volume, while its second, protruding from the cap end with one in any Position fixable control element is to be permanently connected such that each predetermined displacement of the control element, designed as two pairs of collapsible legs or as a rotatably mounted control ring or the like, a predetermined displacement of the piston he forces and that the lower edge of the piston in its initial position, in dep gigkeit of the viscosity of the donated goods, as far as must be removed from the upper edge of the measuring space that a gap "S" for filling the underlying measuring space with the donation arises and that from one and the same measuring space each different amounts of donated goods are precisely metered , wherein the beginning of a respective dosing, depending on the amount of dosed donation and the maximum volume of a measuring chamber begins either in the above-described starting position of a piston, or between any two markings of a cap takes place, especially if small amounts of the donated to are dosing and that even with a release of a maximum dosage of a donation from a dosing his measuring room does not necessarily have to be empty.

Everyone is according to the invention Position of a control element with respect to a cap, a certain, immutable Location of a piston assigned in the measuring room and thus with each change the position of the control element, the piston is accordingly relocated and released a defined amount of the donated goods, this being done by deliberately pushing apart two pairs of legs, in which the pressure is exerted on the middle joints and the protruding end is up to the mark or until it stops, or by turning a control ring as far as one Mark applied to it with the given mark at cap covers.

is the control element is designed as two pairs of legs or the like, are their upper joints with the cap firmly and permanently to connect while the outstanding end of a leadership and dispensing tubes, via a connecting element or directly, by means of lower joints with each under arranged Leg must remain permanently connected, or if the control element is designed as a control ring or the like, must be support by means of a thread or a guide pin and a channel respectively.

According to the invention is too guarantee that while the dosing a control element or the like with a its areas are firmly but movably supported on a cap while being another area the leadership and dispensing tube and thus the piston precisely directs and thus an exact dosage of the donated or his backsliding inside a container causes.

• – einer, mit einer Führungsöffnung in ihrem Boden versehener, zweckmäßig gestalteten Verschlusskappe an der mindestens ein Paar zusammenklappbarer Schenkel die im oberen Bereich mit der Verschlusskappe und im unteren Bereich mit einem Befestigungselement dauerhaft jedoch kippbeweglich verbunden sind, wobei zwischen beiden Schenkel auch ein kippbewegliches Mittelgelenk angeordnet werden muss und, dass die Form und der Beweglichkeitsbereich der Gelenke so gewählt und auf die Länge des Führungs- und Ausgaberöhrchens abgestimmt werden muss, dass in ihrer maximal zusammengeklappten Lage, zwischen einem Kolben und dem oberen Messraumrand der Verschlusskappe, ein ausreichend großer Spalt vorhanden ist, über den die Füllung des Messraumes mit einem Spendengut möglich ist und, dass auch bei maximal ausgestreckten Lage der Schekel eine maximale Menge des Spendensgutes aus einem Messraum dosierbar ist, und dass der Ausgangswinkel (α) zwischen den zusammenwirkenden Schenkel größer als 5 Grad sein muss und der Endwinkel (β) kleiner als 175 Grad sein muss, um eine einwandfreie Verlagerung der Schenkelpaare von einer Ausgangsposition in die Endposition und umgekehrt zu garantieren. Nach einem abgeschlossenen Dosiervorgang muss der Kolben in seine Ausgangsposition verlagert werden, wenn ein neuer Dosiervorgang erfolgen sollte, was beispielsweise mittels Aufsetzen einer Schutzkappe auf eine Verschlusskappe erfolgen kann;
• – einem Führungs- und Ausgaberöhrchen dessen rausragendes Ende mit einem Steuerungselement der als ein Steuerungsring gestaltet ist, dauerhaft verbunden ist und durch die Drehbewegung des Steuerungsringes der Kolben, wie oben beschrieben präzise steuerbar ist und eine gewünschte Menge des Spendenguts abgibt.

The invention has the advantage that in its simplest, most cost-effective embodiment, a metering system can be formed from only two elements, namely:

• - One, provided with a guide opening in its bottom, suitably designed cap on the at least one pair of collapsible legs which are permanently but tiltably connected in the upper part with a fastener and in the lower part with a fastener, wherein arranged between the two legs and a tiltable middle joint and that the shape and range of motion of the joints must be chosen and tuned to the length of the guide and dispensing tube such that there is a sufficiently large gap in their maximally collapsed position, between a piston and the upper edge of the measuring chamber , via which the filling of the measuring space with a donation is possible and that even with maximum stretched position of the shekel a maximum amount of the donated good from a measuring space can be dosed, and that the initial angle (α) between the cooperating legs greater must be at least 5 degrees and the final angle (β) must be less than 175 degrees to ensure proper shifting of the pairs of legs from a home position to the final position and vice versa. After a completed dosing the piston must be moved to its original position when a new dosing should take place, which can be done for example by placing a protective cap on a cap;
• A guide and dispensing tube whose protruding end is permanently connected to a control element designed as a control ring, and by the rotational movement of the control ring the piston is precisely controllable as described above and delivers a desired amount of the dispensing material.

An important feature of the invention is that while pressing on the middle joints of the two, in the starting position leg pairs, their spreaders and thereby their associated piston together with the guide and dispensing tube, from its initial position in which he is a gap "S" forms, first displaced in the direction of the measuring space until this gap "S" is closed liquid-tight and at the same time a dense measuring space is formed, from which by further exertion of pressure on the middle joints of the legs, a further displacement of the piston in Direction of a cap bottom is carried out and a squeezing of the desired amount of a donation is forced, this process is abbruch at the latest after reaching a maximum angle between the legs, which must always be less than 180 degrees, ab, which can be realized for example by a limitation of legs or by a stop on the guide and Ausgaberöhrchen. According to the invention, the maximum spreading of the legs is to be limited to an angle (β) such that, in the event of a later pressure being exerted on the end face of the guide and dispensing tube, the leg pairs shift back into their starting position without problems, up to the angle (α). and thus the piston reaches its initial position in which it forms a gap "S" for filling the measuring space, wherein this end position of the guide and dispensing tube can be determined for example by means of a stop between the connecting element and the bottom of the closure cap.

Important in the invention is that the angle between two cooperating Legs of a pair, in their initial or final position always maximum be that big may be that their further stretching or merging effortlessly can if on the middle joints of the two thigh pairs or Front of the protruding end, a pressure is applied.

A inventive arrangement a piston at the, a measuring chamber facing the end of a guide and output tubes and its displacement type according to the invention has a very important advantage in that with its shift in the initial phase, in the direction of a measuring room, always a stepping out of the management and dispensing tube from the interior of a container is connected and thereby always a low negative pressure in his Inside is created by sucking in the air over the Emptying channel is always balanced and thus a premature Emergence of a donation from the dosing system according to the invention prevented as long as the measuring chamber with the piston is not liquid-tight is closed. From this time, in another step out of the management and dispensing tube from the measuring room, the donated goods in it will shrink by a measuring space volume Piston movement always to a greater degree be compacted, as the further outward leaping section of the guide and dispensing tube it can compensate and thus an overpressure is generated between the piston and the measuring chamber floor, the one desired The amount of the donated good can be squeezed out as long as the control elements move. Will the operation the control elements is interrupted, the Spendengutaustritt immediately or with a lesser delay as soon as the overpressure in the Measuring room is dismantled, interrupted.

Consequently is always in the initial phase of a metering process according to the invention guarantees that no unintentional, a metered amount falsifying Emergence of a donated property takes place and that only after one Sealing the measuring space only the desired amount of donated goods it comes out, as long as an overpressure is present in the measuring room. If a dosing process is interrupted prematurely, For example, on an outward end of a managerial and dispensing tube or on the circumference of a cap applied scale directly or indirectly, the amount of donated goods taken has been.

• – fängt ein Dosiervorgang in der Ausgangsposition eines Kolbens an, kann die dosierte Menge des Spendengutes direkt auf einer Skala abgelesen werden, in dem die Lage der Markierung am Steuerungselement mit der die abgegeben Menge bestimmender Markierung an Verschlusskappe oder am Führungs- und Ausgaberöhrchen verglichen werden;
• – wird als Anfang eines Dosiervorgangs, das Ende eines vorherigen Dosiervorganges festgelegt, muss bei der Bestimmung der dosierten Menge des Spendengutes diese von der gezeigten Menge subtrahiert werden, wobei bei derartigem Dosiervorgang ist darauf zu achten, welche Restmenge eines Spendengutes noch zur Verfügung steht, wenn man in einem Schritt dosieren will.

An important feature of the invention are the following two dosing possibilities of a donated good, regardless of whether its removal by means of spreadable leg pairs or by means of control ring takes place:

• - If a dosing starts in the initial position of a piston, the metered amount of the donated goods can be read directly on a scale in which the position of the mark on the control element with the dispensed amount determining mark on cap or on the guide and dispensing tube are compared;
• - Is set as the beginning of a dosing, the end of a previous dosing, must be subtracted from the amount shown in the determination of the metered amount of the donor, with such dosing is to pay attention to what residual amount of donated goods is still available, if you want to dose in one step.

According to the invention Cross section of an emptying channel always so on the viscosity of the metered Donate good adapt that on the one hand only a slight overpressure is built in the measuring room until its coming out, on the other hand must This cross section guarantee that after the overpressure is degraded in the measuring room, no further emergence of the donated goods takes place, which is an important feature of the invention.

Further important embodiment of the invention provides that a control element in the form of a separate, movable but fail-safe on the circumference a closure cap attached control ring is formed, wherein its displacement, for example by means of a threaded connection or a guide nose in a guide channel guided is, or the like, wherein the guide lug on a control ring and the guide channel can be attached to the circumference of a cap, or vice versa.

A dosing is carried out by an indirect transfer of a displacement of a control ring described above, the front part is permanently connected to the protruding end of a guide and dispensing tube permanently on the piston, wherein the axial displacements must always be the same or almost equal, and this as far as possible unyielding connection between the control element and guide and Ausgaberöhrchen and between leadership and Output tube and the piston is to realize, which is an important feature of the invention.

Becomes the control ring turned until the mark applied to it, For example, a notch, with a line of a scale the on the outside wall A cap is applied, one was covered with her defined amount of the donation good issued as soon as the emergence of the donated property stops.

Should a last drop of a donated item gets stuck at a delivery opening, This can be done by turning back of the control ring and a return displacement the piston from the outlet opening be sucked into the emptying channel or into the container interior, which is especially important when dosing toxic substances Invention is.

Also important feature of the invention is that a donation also directly can be mixed before its dosage, if it is made of substances which persists over time in a longer time container decrease.

Very important feature of this invention is that in each embodiment of the Invention is to pay attention that a particular situation change of a Control element, a predetermined displacement of a piston in the measuring room, where he is first with a donation to flood in a container with his head down and after about 2 seconds a control element can be moved, with its movement First, the piston seals the measuring chamber, and from about this time Catches the Dosage of a desired Portion of a donation from the measuring room, in which a control element the Piston in a for this portion intended position, whereby the removal, in dependence of the size of the measuring room, can always be from the initial position of the piston, or between two Markings are made, resulting from a sealed measuring space he follows. For example, a measurement room has a maximum volume of 50 ml and is divided into 5 areas of 10ml each. At a For example, 20 ml of donated goods were taken from the first withdrawal and the remaining 30 ml are still present in the measuring room. Should the next Take, for example, 20 ml, it can also be made from the existing Remainder of the measuring space content are taken in which a control element continue to move to the mark of the second area, wherein the donor material removal described varher is possible.

Consequently can with this device according to the invention donation collection takes place in two ways, provided that the measuring room is sufficiently large and the controls also in between in a precisely defined Position are displaced.

at a rotatably displaceable control element is inventively provided that this is rotated around a cap, or that this held and the cap and container is rotated in it.

Some alternative solutions the invention, in particular for dosing only a predetermined Spendengutmenge, are also particularly inexpensive to produce, in the example a cap including two leg pairs and the fastener with a dispensing and guide tube, as a unit while the dispensing and guide tube and piston as a second element is to produce. Also the assembly by means of Inserting the dispensing and guide tube together Piston in the cap opening and the fastener and its convenient connection, for example by means of an ultrasound machine, is also feasible with most existing assembly systems, whereby the Installation costs can be kept low.

In other solution variants according to the invention can use the protruding end of a guide and dispensing tube many existing, attached to him directly or on cap Cover elements are combined in the example by their displacement, turning or pulling off the dosing and Spendengutresten-removal device open.

There while a metering process, from the moment where the measuring chamber with the piston is sealed, above the piston, a vacuum forms its Size of the Size of the dosed quantity depending on the donation is should, according to the invention in general a measuring room does not exceed 20% of the net volume of a container, if it's a rigid container, for example, made of glass or metal.

is a container made of flexible plastic, the measuring space size can also be larger, which means each Try to set and is an important feature of the invention is to be considered.

Thus, a cost-effective, precisely dosing metering and Spendengutresten- Entnah me device can be realized, which can be realized by means of a one-time adaptation of the manufacturing molds and assembly equipment.

One Another very important feature of the invention provides that a dosing invention and donation debris removal devices also the dosage of one Undetermined amount of donated goods can be done when the piston the measuring room is not yet sealed, but this with a donation already flooded was, this process is feasible only from a resilient container, because they have to be compressed to build up pressure.

In another embodiment The invention provides that, if desired, from the measuring room emerging section of the leadership and dispensing tube protected by a bellows from direct contact with the hands, which is especially important when dosing very toxic substances is and is also an important part of the invention.

the Protection of the invention are also subject to designs in which no bellows as protection, and in which and outlet tubes Also, a scale can be applied permanently, which is then visible is and on its slow emergence from the bottom of the cap Also a relatively accurate information about the metered amount of a Donate good can give.

Also important in the invention is that in the calculation of each metered amount of donation (V) must be from the entire volume of the measuring space always the volume of the adequate Section of a management and dispensing tube withdrawn become.

Also a very important feature of the invention is that virtually all Remains of a donation can be removed from a container, if this directed with his Entnahmevor direction long enough down remains and when the piston is in its home position, so that the gap "S" is sufficiently large to let the donation residues into the measuring room and that while the The edge of the piston far enough from the turn of the container is removed so as not to stop the donation.

Based the accompanying drawings, which do not limit this invention, but the principle of operation of the particularly preferred embodiments more specifically, the main features of the invention become more specific described.

Ways to carry out the invention, wherein in the description the same or corresponding parts are designated by identical reference numerals:
1 shows a longitudinal section of a container ( 23 ) with a dosing and Spendengutreste- removal device according to the invention for a complete removal of liquid Donate, in their working position and starting position, wherein the control element in this example of two pairs movably arranged leg ( 8th ), which are in their initial position at the angle (α), which is between the planes in which the joints ( 24 . 21 . 25 ), and these are the upper legs ( 8th ) each by means of an upper joint ( 24 ) on a cap ( 14 ) permanently but movably fixed and by means of a respective lower joint ( 25 ) with an outstanding end ( 7 ) also fixed permanently and movably. Between both thighs ( 8th ) of a pair is in each case a middle joint ( 21 ) and by a selective pressure on this, in the direction of the arrow, its downward extension and at the same time the movement of the protruding end of a guide and dispensing tube ( 7 ) also down, forcing the movement of the piston ( 4 ) in the direction of the measuring space ( 6 ) So also down, and the emergence of a corresponding section of the guide and Ausgaberöhrchen ( 3 ) from the measuring room ( 6 ), as a result, which causes a generation of a low vacuum during this displacement process and thus premature leakage of the donor material from the measuring space ( 6 ) prevents, as always small portions of air are sucked. Reaches the piston ( 4 ) the position ( 20 ), the measuring room ( 6 ) sealed with him and in its further movement in the direction of the Messraumbodens the measuring chamber volume is reduced much faster than the emerging portion of the guide and dispensing tube ( 3 ) can make up for it, which results from a difference in diameter between the piston (diameter "D") and the guide and dispensing tube (diameter "d"), since the movement sections of the two are each the same size. The position shown here, for example, the inlet opening of the discharge channel ( 2 ) allows virtually a complete removal of the measuring space content, which is always an important feature of the invention. In this example, the inner wall of a container ( 5 ), the side wall of the measuring space ( 6 ), whereby it must be calibrated accordingly, in order to ensure a correspondingly tight connection with the sealing lip ( 19 ) of the piston ( 4 ), but this is not absolutely necessary, since according to the invention the inner wall ( 5 ) of the measuring room ( 4 ) also from the beginning an integral part of the cap ( 14 ), which, however, the cost of these correspondingly more expensive. Is the piston ( 4 ) as shown here in its initial position, must be between the lower edge of the piston ( 11 ) and the upper edge of the measuring space ( 12 ), in at least one place a sufficiently large, on the viscosity of the donated good tuned gap (S) be present, which allows a quick filling of the measuring space - in about 2-3 seconds, when the container ( 23 ) with removal device is directed with his neck down. It is also important that the seal between the cap ( 14 ) and the guide and withdrawal tube ( 3 ) is to be made so that on the one hand their axial, sufficient and easy movement in the cap ( 14 ), on the other hand a predetermined density of this connection is guaranteed. For example, if the item being donated is very poisonous or aggressive, the density may be further enhanced by placing it around the guide and withdrawal tube ( 3 ) a liquid-tight bellows ( 13 ) arranged and with a, in this case, airtight mounted fastener ( 10 ) is permanently connected. The bellows ( 13 ) and the connecting element ( 10 ) should be designed in this case so that the possibly intervening therefrom donation good in a compression of the bellows ( 13 ), back into the measuring room ( 6 ). The illustrated embodiment of the invention is not optimally structured in all areas, such as the seal between the cap ( 14 ) and the container neck, but the functional principle according to the invention is clearly recognizable here.

The 2 essentially shows one of the 1 known in accordance with the invention dosing and Spendengutreste-removal device shown in its piston ( 4 ) in the final position, after a completed dosing process by a previously applied permanent pressure on the middle joints ( 21 ) have the piston ( 4 ), the guiding and dispensing tube ( 3 ) and the thighs ( 8th ) each reaches its end position, wherein the legs ( 8th ) to each other at an angle (β), which must always be less than 180 degrees, in order to ensure a smooth return displacement of the piston ( 4 ) and the guide and dispenser tube ( 3 ) to guarantee. By the displacement of the piston ( 4 ) in the end point shown here, a maximum amount was taken from the donation, taking care that the cross section of the discharge channel ( 2 ) is to be adapted at least at one point to the viscosity of the donated good that after canceling a dosing process in any position of a control element ( 8th or 9 ), the emergence of the donation, after the pressure reduction in the measuring room ( 6 ), stop immediately. According to the invention, the emptying channel ( 2 ) have an arbitrary course and a cross section that is the same or different everywhere, whereby its inlet opening is always to be placed in such a way that the emptying chamber is emptied, in particular in its final phase. The material, especially plastic, must be chosen so that the joints ( 21 . 24 . 25 ) at least as often fulfill their task perfectly, how many portions of the donated goods in the container ( 23 ) are located. After aligning the container with the cap ( 14 ) upwards, is in the final position in the measuring room ( 6 ) located piston ( 4 ) by applying pressure to the connecting element ( 10 ) and / or on the outwardly projecting end of the guide and dispensing tube ( 7 ), for example by means of a finger or a cap in the direction of arrow, in its initial position in which he with the upper edge of a measuring space ( 12 ) forms a gap (S) to relocate. The outlet opening ( 18 ) remain at least partially free to the air inflow into the measuring space ( 6 ). The bellows shown here ( 13 ) is not absolutely necessary in every version, especially not if no poisonous and / or aggressive donation is to be dosed. Is at For example, dishwashing detergent, fabric softener, a cough syrup or the like dosed with it, is recommended on this bellows ( 13 ), whereby the outward from the bottom of a cap ( 1 ) protruding end of a guide and dispensing tube ( 7 ) becomes visible and thus, according to the invention, a scale can be applied to it which, when the limb pairs are moved slowly ( 8th ) can be considered relatively accurately, since the leg pairs ( 8th ) spread only over part of the circumference, which is clearly evident in the 6 can be seen. Thus, even a smaller portion than the maximum can be selectively metered. Although this embodiment is not illustrated here, it is subject to the protection of this invention.

In the 3 is a container in longitudinal section ( 23 ) with a further embodiment of a metering and Spendengutreste- removal device according to the invention for a complete removal of liquid donation in its initial position, in which case as a control element a separately producible control ring ( 9 ), which in an area with the cap ( 14 ) is positioned by means of a threaded connection and in its front region with the protruding end ( 7 ) of a guide and suction tube ( 3 ) permanently and firmly connected. The control ring ( 9 ) can be molded as a full cap or as a cap with recesses. By the combination of a movable attachment by means of a threaded connection and a fixed connection with the protruding end of a guide and dispensing tube ( 3 ) and thus with the piston ( 4 ) can by a rotational movement of the control ring ( 9 ), The piston ( 4 ) are accurately and specifically, axially and shifted back and forth. Will he be in his starting position in the 3 is shown displaced, a gap (S) for filling the measuring space ( 6 ), what happens when the container ( 23 ) is directed with removal device down. According to the invention, the control ring ( 9 ) at its upper area a permanent mark ( 15 ), while the cap ( 14 ) at its periphery a, in particular spirally extending, permanent scale ( 16 ), wherein its direction and pitch must correspond to the pitch and direction of the thread in approximately, wherein the smaller the thread of the threaded connection the more accurate the dosage of the donor good. This scale ( 16 ) is to be provided with numbers at predetermined intervals in such a way that a user can immediately notice over which volume the marking on the control ring ( 15 ) located. As a further, important embodiment of the invention is a guide of a control ring ( 9 ) by means of a permanently attached to him guide nose in a guide channel on the circumference of a cap ( 14 ) is to install. If this arrangement is reversed, that is, the guide channel in the control ring ( 9 ) and the guide lug on the circumference of the cap ( 14 ), the guide nose must be approximately at the level of its bottom ( 1 ) lie around the entire height of the control ring ( 9 ) make sense to use. As one of many possible limitations of the movement of a piston ( 4 ) here is a stop ( 17 ), which can be attached continuously or only in one place. The attack ( 17 ) must always be located below an inlet opening of an emptying channel ( 2 ). If the course of the evacuation channel ( 2 ) as in the 1 and 2 shown, no stop is designed here ( 17 ), because by adjusting the active length (L) of the guide and dispensing tube ( 3 ) between the lower edge of a piston ( 11 ) and the connecting element ( 10 ) to the active height (H) of the control ring ( 9 ), it is always possible to jump out of the control ring ( 9 ) to prevent its guidance in its final position when the height (H) is not much smaller than the length (L). According to the invention, it is recommended that these (H and L) are approximately the same size. An important feature of this invention is that this principle described above also in another inventive embodiment of the invention, in which the leadership of the piston by means of a guide nose and a guide channel in the control element and on the cylindrical surface of a cap ( 14 ) are mounted, or vice versa, unein restricted used. Of course, in this embodiment, for example, a piston ( 4 ) together with guide and dispenser tubes ( 3 ) from the 2 are known, with a control ring schematically shown here ( 9 ) and is also content of this invention. Since most cost-effective embodiments of the invention are important for product manufacturers, the formation of the measuring space ( 6 ) from a calibrated inner wall of a container ( 5 ), but what the inner wall as a, for example, plastic and in the same passage as the cap ( 14 ) producible element includes this invention.

4 shows one from the 3 known metering and dispensing residue removal device according to the invention in its final position and after completion of dosing, wherein the end position of the piston ( 4 ) in the measuring room ( 6 ) by means of a stopper proposed in this embodiment ( 17 ) is fixable. The during the dosing, by means of a rotary movement of the control ring ( 9 ), dispensed dosage amount of the donation (V) is pictorially represented as a ring whose height is the distance between the lower edge of the piston shown in broken line ( 11 ' ) and the lower edge of the solid-line piston ( 11 ). The length of a guide and dispensing tube ( 3 ) and the position of the connecting element ( 10 ) at her must be so chosen be that even when dosing a maximum amount of donated, the control ring ( 9 ) still a sufficient guide on a cap ( 14 ), which protects it from falling out, regardless of whether the connection between them by means of a thread or by means of a guide nose and a guide channel has been realized and is also an important feature of the invention.

In the 5 is a side view on one of the 4 known dosing and Spendengutreste- removal device, with the difference that the piston ( 4 ) has not yet reached its final position, which is clearly evident from the fact that the control ring ( 9 ) of the dosing system indicates the quantity dispensed by 10 ml, while in its further rotation the 15 ml mark on the scale can be reached. If a 5 ml portion is removed from this dosing system according to the invention, a piston ( 4 ) by turning back the control ring ( 9 ) are displaced to its original position and starting from this position, are rotated to the mark 5 ml, or it can from the mark ( 16 ) - 10 ml - go out and by turning the control ring ( 9 ) until the mark ( 15 ) reaches the mark - 15 ml - also the 5 ml portion can be removed, which is an important feature of the invention.

The 6 shows one of many possible embodiments of a one-piece cap ( 14 ) In a plan view from above, the constituent part of a metering and Spendengutreste- removal device according to the invention from the 2 is known. Here it is clear that the thighs ( 8th ) are to be produced in particular as straight running elements whose width, depending on the material and the maximum forces to be transmitted by means of this and the width of the joints ( 21 . 24 . 25 ) are always designed so that they survive unscathed at least the predetermined number of buckling and Spreitz movements, which can be determined by means of experiments.
