摘要:
The proposal is for a writing device (10) comprising a reservoir (11) with an aperture (12) in which the writing fluid (13) is freely held and an at least partially capillary feed line (14) for the writing fluid (13) which connects the reservoir (11) to the writing head to feed writing fluid (13) and a capillary store connected to the feed line (14). The feed line (14) fills the aperture (12) and is in direct contact with the capillarity store (16), whereby the capillary of the capillarity store (16) is on average lower than that of the feed line (14), at least in the aperture (12) of the reservoir (11).

Solids which are soluble in a common solvent or solvent mixture, possibly containing a common high-boiling substance, of common marker liquids for writing instruments with a common capillary feeder opening, with a melting point 30° C and a molecular weight 1000 daltons, and which, when they are the sole ingredient in the solvent or solvent mixture, crystallize on the feeder opening, forming outwardly growing crystallites, can be used as antiblocking additives for such marker liquids in a proportion of at least 1 % in weight, relative to the final composition of the marker liquid, for protective and anti-evaporating closure of the capillary feeder opening when it is unprotected and not in use.
摘要:
The invention relates to a device for controlling the fluid supply of a consumer element, comprising a fluid reservoir (14), a fluid supply line (18, 20, 36, 24) leading from the fluid reservoir to the consumer element and a valve in the fluid supply line. The valve element (22) of said valve independently opens the valve opening (20) whenever downstream from the valve the consumer element has used a preset quantity of fluid. Said device is characterized in that the valve is a capillary valve and contains a capillary space (36) positioned downstream from the valve opening and connected to the fluid supply line, said capillary space being partly delimited by the valve element. Said valve element closes the valve opening by the capillary force generated by the fluid in the capillary space when said capillary space is filled with a predefined volume of fluid.

The proposal is for a device (10) for filling writing, drawing, printing and painting instruments or writing fluid reservoirs (writing instruments) (11) with writing, drawing, printing or painting fluid (writing fluid) (13), comprising a container (14) with an aperture to hold the writing fluid (13), the interior (15) of which communicates with the atmosphere (19) and a capillary fluid transport connection (16) through which the writing fluid is conveyed from the inside of the container to the writing instrument. A device (17) to take the writing instrument (11) is sealed in the container aperture and one end of the capillary fluid transport connection (16) opens into the instrument (17) and contacts a writing point (12) or an aperture in the writing instrument (11). The connection to the atmosphere (19) is provided via a line (18) passing through at least one chamber (23; 183).
摘要:
Il est proposé un dispositif (10) de remplissage d'instruments à écrire, dessiner, imprimer ou peindre ou bien de réservoirs de liquide d'écriture (instruments à écrire) (11) avec des liquides pour écrire, dessiner, imprimer ou peindre (liquides pour écrire) (13), comprenant un réservoir (14) équipé d'une ouverture pour recevoir le liquide pour écrire (13) dont la partie interne du réservoir (15) est reliée à l'atmosphère (19), de même qu'une jonction capillaire de transport du liquide (16), par laquelle le transport du liquide pour écrire s'effectue depuis l'intérieur du réservoir vers l'instrument à écrire. Un mécanisme (17) recevant l'instrument à écrire (11) est introduit de manière étanche dans l'ouverture du réservoir et l'un des côtés de la jonction capillaire de transport du liquide (16) débouche dans le mécanisme (17) et arrive au contact d'une pointe à écrire (12) ou de l'ouverture de l'instrument à écrire introduit (11). La communication avec l'atmosphère (19) s'effectue par une conduite (18) qui traverse au moins une chambre (23; 183).
摘要:
Il est proposé un instrument d'écriture (10) comprenant un réservoir (11) présentant une ouverture (12), dans lequel le liquide d'écriture (13) est contenu librement, un conduit d'alimentation au moins partiellement capillaire (14) pour le liquide d'écriture (13), reliant le réservoir (11) à la pointe d'écriture, ainsi qu'un réservoir capillaire associé au conduit d'alimentation (14). Le conduit d'alimentation (14) occupe la totalité de l'ouverture (12) et est directement en contact avec le réservoir capillaire (16), la capillarité de ce dernier étant en moyenne plus faible que la capillarité en moyenne du conduit d'alimentation (14), au moins dans l'ouverture (12) du réservoir (11).
