Abstract

The ink cartridge for use in ink jet printers utilises a flexible container that is emptied by application of air pressure. The ink container is in the form of a flexible bay (1) that is supported within a rigid housing (3) and is sealed from the atmosphere. A flexible pressure ball (5) is mounted in the end of the housing and has a volume of approximately one half that of the free space in the housing. When pressure is applied, the ink is expelled from a nozzle in the end of the housing.

Description

Vorrichtung zur Entnahme von Tinte aus Patro-Device for removing ink from cartridge

nen für Tintenstrahlschreiber Die Erfindung betrifft eine Vorrichtung zur Entnahme von Tinte aus Patronen für Tintenstrahlschreiber mit Hilfe von Druck, wobei der eigentliche Tintenbehälter aus nachgiebig-elastischem Material sich in einer Hülse (Patrone) aus starrem Material befindet.Inkjet Pens The invention relates to an apparatus for removing ink from cartridges for inkjet pens with the help of pressure, wherein the actual ink container made of resilient material is in a sleeve (cartridge) made of rigid material.

Solche Tintenpatronen wurden bisher mit Hilfe eines Druckschiebers entleert, indem der in der Patronenhülse entstandene Überdruck den flexiblen Innenbehälter im Ausmaß seiner Entleerung in sich zusammenfallen ließ.Such ink cartridges were previously with the help of a pressure slide emptied by the overpressure created in the cartridge case pushing the flexible inner container collapsed to the extent of its emptying.

Diese Handhabung ist umständlich und unzuverlässig hinsichtlich der Druckdosierung. Der Erfindung liegt die Aufgabe zugrunde, eine einfache und auch für geringe Druckunterschiede präzise Ausführung zu finden.This handling is cumbersome and unreliable in terms of Pressure dosing. The invention is based on the object of a simple and also to find precise execution for small pressure differences.

Die Lösung dieser Aufgabe besteht darin, daß am rückwärtigen Ende der starren Patronenhülse eine Öffnung angeordnet ist, die von einem Mundstück eines Druckballes verschlossen wird, dessen Volumen etwa die Hälfte des Freiraumes der Patronenhülse (Volumen der Hülse abzüglich Volumen des gefüllten Tintenbehälters) entspricht.The solution to this problem is that at the rear end the rigid cartridge case has an opening arranged from a mouthpiece of a Pressure ball is closed, the volume of which is about half the free space of the Cartridge case (volume of the case minus the volume of the filled Ink tank) is equivalent to.

Mit Hilfe genau dosierbarem Druckes kann im Innern der Patronenhülse der Druck kurzzeitig oder anhaltend so erhöht werden, daß der Innenbehälter im Ausmaß seiner Entleerung in sich zusammenfällt und somit ein ständig gleichmäßiger Tintenfluß zur Schreibspitze stattfindet.With the help of precisely metered pressure, inside the cartridge case the pressure can be increased briefly or continuously so that the inner container to the extent its emptying collapses and thus a steady flow of ink takes place at the writing tip.

Die Erfindung kann in zwei verschiedenen Ausführungsformen verwirklicht werden, die an Hand der anliegenden Skizze näher erläutert sind.The invention can be implemented in two different embodiments which are explained in more detail on the basis of the attached sketch.

Figur 1 zeigt einen Tintenbehälter (1) aus nachgiebig-elastischem Material, der in einer starren Hülse (3) eingebaut ist, wobei sich zwischen der Innenseite der Hülse (3) und der Außenseite des Behälters (1) ein Freiraum ergibt, in dem sich Druckunterschiede auswirken können. Die starre Hülse (3) ist rückseitig mit einer Öffnung (4) versehen, die durch das Mundstück eines Druckballes (5) verschlossen ist, dessen Volumen etwa der Hälfte des Freiraumes (2) entsprechen soll. Bei Ausübung eines Druckes (P) auf den Druckball (5) wird der Druck im Freiraum (2) derart erhöht, daß der nachgiebig-elastische Tintenbehälter (1) im Ausmaß seiner Entleerung in sich zusammenfällt.Figure 1 shows an ink container (1) made of resilient elastic Material that is built into a rigid sleeve (3), with between the Inside of the sleeve (3) and the outside of the container (1) results in a free space, in which pressure differences can affect. The rigid sleeve (3) is on the back provided with an opening (4) which is closed by the mouthpiece of a pressure ball (5) is, the volume of which should correspond to about half of the free space (2). When exercising a pressure (P) on the pressure ball (5), the pressure in the free space (2) is increased in such a way that that the resilient elastic ink container (1) to the extent of its emptying in collapses.

In Figur 2 ist die gleiche Vorrichtung zur Entnahme von Tinten aus Patronen für Tintenstrahlschreiber mit Hilfe von Druck dargestellt, diesmal jedoch mit einem verlängerten Mundstück für den Druckball (5) wobei dieser mit dem verlängerten Mundstück einmalig im Gerät selbst eingebaut ist und nicht mit jeder Patrone neu einzusetzen ist.In Figure 2 is the same device for removing inks from Cartridges for inkjet pens shown with the help of pressure, but this time with an extended mouthpiece for the pressure ball (5) with this with the extended The mouthpiece is installed once in the device itself and is not new with each cartridge is to be used.
