Description

Tropf- und Dosierflasche Ilüssigkeiten, die in kleinen Quantitäten dosiert werden1 kommen entweder in Flaschen mit angebauter, eingesetzter oder aufgeschraubter Tropfvorrichtung in den Handel, oder es werden normalen Flaschen Tropfpipetten oder lviessgläschen beigelegt. Pipetten und Nessgläser erlauben bei grösseren Flüssigkeitsquentitäten zwar eine einfachere Dosierung als die üblichen Tropfflaschen, sind jedoch bei kleinen Flüssigkeitsmengen umständlicher in der llandhabung, müssen evtl. nach Gebrauch gereinigt werden und bedingen in jedem Fall einen höheren Material- und Zeitaufwand. Drip and dosing bottle for liquids that come in small quantities be dosed1 come either in bottles with attached, inserted or screwed on Dropper in the trade, or normal bottles dropper pipettes or Glass vial enclosed. Pipettes and ness glasses allow for larger liquid quantities Although a simpler dosage than the usual dropper bottles, they are small Liquid quantities, which are more laborious in the oil handling, may have to be used after use be cleaned and in any case require more material and time.

Wünschenswert ist eine Flasche, die nicht nur als Vorratsgefäss dient, sondern je nach Wahl sowohl ein tropfenweises Entnehmen der Flüssigkeit als auch die sofortige Entnahme einer nach Kubikzentimeter bemessenen Flüssigkeitsmenge gestattet, d.h. die Vorzüge einer Tropfflasche mit denen einer Pipette und eines Elessgläschens vereinigt. Zweckmässig ist ferner, dass sie in gleicher Weise wie Flaschen mit angebauter Tropfvorrichtung aus einheitlichem Material besteht und möglichst in einem einzigen Fertigungsgang hergestellt werden kann.A bottle that not only serves as a storage vessel is desirable, but, depending on the choice, both a drop-by-drop removal of the liquid and allows the immediate withdrawal of a quantity of liquid measured in cubic centimeters, i.e. the advantages of a dropper bottle with those of a pipette and an Eless glass united. It is also useful that they are grown in the same way as bottles The drip device consists of a single material and, if possible, in a single one Production process can be produced.

Diese Forderungen werden erfüllt durch eine elastische Kunststoff-Flasche, mit der nach den beiliegenden Zeichnungen 1 und 2, die einen Längsschnitt in der Symmetrieebene wiedergeben, sowie nach Zeichnung 3 (Aufsicht von vorn) ein pipettenförmiger zylindrischer Ausguss (4) verbunden ist. Eine Kommunikation (5) zwischen Pipettenlumen (6) und Flascheninnern (7) bewirkt, dass sich bei leichtem Neigen (1) der Flasche die Pipette füllt und dass bei anschliessendem Waagerechthalten (2) der Flasche eine bestimmte Flüssigkeitsmenge, die nicht mehr über die Kommunikationsöffnung (5) ins Flascheninnere zurückfliessen kann, in der Pipette verbleibt.These requirements are met by an elastic plastic bottle, with the one according to the accompanying drawings 1 and 2, which is a longitudinal section in the Reproduce the plane of symmetry, as well as a pipette-shaped one according to drawing 3 (top view from the front) cylindrical spout (4) is connected. A communication (5) between pipette lumens (6) and the inside of the bottle (7) causes that when the bottle is tilted slightly (1) the pipette fills and that when you then hold the bottle horizontally (2) a certain amount of liquid that no longer passes through the communication port (5) can flow back into the inside of the bottle, remains in the pipette.

Wird die Entfernung der Kommunikation von der Pipettenspitze bzw. das Lumen der Pipette so bemessen, dass bei waagerechter Haltung 1 ccm in der Pipette verbleiben, und wird die Pipette graduiert, so kann ein beliebiger Bruchteil von x dadurch entnoen werden, dass durch leichten Druck auf die Flaschenwand der in der Pij>ette befindliche Flüssigkeitsnieniskus entsprechend herabgedrückt wird. Zweckmässigerweise wird die Pipettenspitze so eng gehalten, Iass ein Abtropfen erst durch Druck auf die ilaschenwand erfoll. Eine Xerschlusskappe (8) sichert eventuell einen guten Verschluss der Pipettenspitze nach Gebrauch.If the distance of the communication from the pipette tip or dimension the lumen of the pipette so that 1 ccm in the pipette when positioned horizontally and if the pipette is graduated, any fraction of x can be denoned by the fact that by applying light pressure on the bottle wall the fluid streak located in the pij> ette is correspondingly pressed down will. The pipette tip is expediently held so tightly that it drips off only fulfilled by applying pressure to the wall of the flap. A locking cap (8) may secure a good closure of the pipette tip after use.

Bei Flaschen gemäss vorstehender Beschreibung, die jedoch aus starrem lwandmaterial, z.B. Glas, bestehen, kann der zur Entleerung erforderliche Luftdruck durch einen mit dem Flascheninnern in der bindung stehenden, ausserhalb der Flasche angebrachten elastischen Ballon erzeugt werden. So ist es beispielsweise möglich, nach Zeichnung (9) ein elastisches, ballonartig erweitertes Pipettenansatzstück der oben geschilderten Formgebung auf eine elastische oder starre grössere Vorratsflasche (leu) so aufzubringen, z.B. durch Schraubgewinde, dass nach automatischer Füllung der Pipette durch Druck auf die Wandung bei (11) eine Entleerung der Pipette erfolgen kann.For bottles as described above, but made of rigid wall material, e.g. glass, the air pressure required for emptying can be used by one outside the bottle that is bound to the inside of the bottle attached elastic balloon can be generated. For example, it is possible according to drawing (9) an elastic, balloon-like expanded pipette attachment piece the shape described above on an elastic or rigid larger storage bottle (leu) to be applied, e.g. by screw thread, that after automatic filling The pipette can be emptied by pressing the wall at (11) can.

Patentanspruch: 1. Flasche aus elastischem Material mit organisch verbundenem pipettenförmigen Ausguss, die mittels Druck auf die Flaschenwand die wiederholte Entnahme einer bestimmten, dem Fassungsvermögen der Pipette entsprechenden Flüssigkeitsmenge oder eines Teiles dieser Menge dadurch gestattet, dass die Kommunikationsöffnung zwischen Flascheninnern und Pipettenlumen so angebracht ist, dass durch Neigen und anschliessendes Waagerechthalten der Flasche eine automatische Füllung der Pipette erfolgt.Claim: 1. Bottle made of elastic material with organic connected pipette-shaped spout, which by means of pressure on the bottle wall the repeated removal of a certain volume corresponding to the capacity of the pipette Liquid amount or a part of this amount thereby allowed that the communication opening is attached between the inside of the bottle and the pipette lumen in such a way that by tilting and then hold the bottle horizontally and automatically fill the pipette he follows.

Claims (1)

2. Flasche nach Anspruch 1, dadurch gekennzeichnet, dass die Pipette nicht mit der Flasche organisch verbunden ist, sondern mittels eines Schraub- oder Schnappverschlusses so angebracht wird, dass nach erfolgter Verbindung die automatische Füllung in der unter 1 beschriebenen Weise erfolgen kann.2. Bottle according to claim 1, characterized in that the pipette is not organically connected to the bottle, but by means of a screw or Snap lock is attached in such a way that the automatic Filling can be done in the manner described under 1. 3. Flasche nach anspruch 1 aus starrem w-ndmaterial, bei der der zur Entleerung der Pipette erforderliche Luftdruck durch einen auf das Flascheninnere einwirkenden elastischen Ballon erzeungt wird. L e e r s e i t e3. Bottle according to claim 1 made of rigid wall material, in which the for Emptying the pipette by applying the required air pressure to the inside of the bottle acting elastic balloon is generated.
