Opfindelsen angår en farvebeholder til skabelontrykkemaskiner, som har et efterløbsstempel og er forsynet med markeringslinier på sin kappeflade, hvilke markeringslinier er synlige gennem en viseråbning på skabelontrykkemaskinen pg tjener 5 til visning af indstillingen af farvetilføringsmekanismens . i ···;+> farveafgangsåbninger.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a color container for template printing machines having a post stamp and provided with marking lines on its casing surface, which marking lines are visible through a pointer opening on the template printing machine and serves to display the setting of the ink supply mechanism. in ···; +> color exit openings.

En farvetilførselsmekanisme til skabelontrykkemaskiner, i hvilken en sådan farvebeholder finder anvendelse, er beskrevet i DE-PS 1.044.830. Denne farvetilførselsmekanisme hår 10 perforerede farverør, der med henblik på indstilling å£ farve-fordelingen kan drejes imod hinanden, hvorved farveafgangs-åbningerne er indstillelige og det bliver muligt at indfarve skabelonen enten over dens fulde bredde eller i et bestént afsnit. Ved at farvebeholderen er forsynet med markeringsli-15 nier, som er synlige gennem en viseråbning i maskinens beklædning, og ved at farvebeholderen er således koblet til det drejelige farverør, at det følger dettes drejebevægeIse, kan indstillingen af farveafgangsåbningerne kontrolleres af maskinens operatør.A color delivery mechanism for template printing machines in which such a color container is used is described in DE-PS 1,044,830. This color supply mechanism has 10 perforated color tubes which, for the purpose of adjusting the color distribution, can be rotated against each other, whereby the color output openings are adjustable and it becomes possible to color the template either over its full width or in a fixed section. By providing the color container with marking lines visible through a pointer opening in the casing of the machine and by the color container being so coupled to the rotatable color tube as to follow its rotational movement, the setting of the color discharge openings can be controlled by the machine operator.

20 Ved disse beskrevne farvebeholdere udsuges farven ved hjælp af en farvepumpe i skabelontrykkemaskinen„ For at undgå en sugning af luft ind i farvetilførlngsmekanismen, er farvebeholderen forsynet med et imod beholderens indervæg under tætning anliggende efterløbsstempel. Det skal bemærkes, at dette 25 princip kun er sikret, når den fremstillingsteknisk betingede konicitet af beholderens indervæg er lille. Overskrider koni-citeten en bestemt størrelse klemmer efterløbsstemplet eller der opstår utætheder. Den nødvendige lille konicitet lader sig efter almindelig opfattelse kun tilvejebringe ved metal-30 beholdere.20 In these described color containers, the color is extracted by means of a color pump in the template printing machine "In order to avoid suction of air into the color supply mechanism, the color container is provided with a sealing post adjacent to the inner wall of the container. It should be noted that this principle is only ensured when the manufacturing-conditional conicity of the inner wall of the container is small. If the continuity exceeds a certain size, the trailing piston pinches or leaks occur. The small conicity required is generally available in metal containers only.

De bekendte af aluminium véd flydepresmetoden fremstillede farvebeholdere kan fremstilles med tilstrækkelig lille konicitet af indervæggen. De har dog den ulempe, at de er dyre at fremstille, og at væggen er ugennemsigtig, således at far-35 veforrådet kun vanskeligt lader sig kontrollere. Til kontrol 2 U 2229 må dej: på stempelenden indføres en stang, på hvilken farveforrådet, når stangen støder imod stemplet, kan aflæses.The well-known color containers made of aluminum by the float method can be manufactured with sufficiently small conicity of the inner wall. However, they have the disadvantage that they are expensive to manufacture and that the wall is opaque so that the paint supply is difficult to control. For control 2 U 2229 dough: a rod must be inserted on the piston end, on which the color supply, when the rod abuts against the piston, can be read.

Der kendes også medf.eks. tætningsmidler fyldte beholdere, som kan isættes i arbejdspistoler, og som er sprøjtestøbt 5 af plast. Disse beholdere har imidlertid et stempel, som forskydes ved hjælp af en stempelstang for at trykke tætningsmidlet ud af beholderen. Koniciteten af disse beholderes in-dervæg er så stor, at et skubbet stempels funktion ganske vist ikke forringes, men at de ikke er anvendelige for efterløbs-10 stempler.Also known are e.g. sealants filled containers which can be inserted into working guns and which are injection molded 5 of plastic. However, these containers have a piston which is displaced by means of a piston rod to push the sealant out of the container. The conicity of the inner wall of these containers is so great that the function of a pushed piston is not impaired, but that they are not applicable to post-pistons.

Opfindelsen har til formål at tilvejebringe en farvebeholder af den angivne art, ved hvilken ikke alene indstillingen af farveafgangsåbningerne, men også farveforrådet på enkel og hurtig måde kan kontrolleres, og hvor farvebeholderen kan 15 fremstilles enkelt og billigt.The invention has for its object to provide a color container of the specified kind, in which not only the setting of the color discharge openings but also the color supply can be controlled in a simple and rapid manner, and wherein the color container can be manufactured simply and cheaply.

Dette formål tilgodeses ved, at farvebeholderen er fremstillet af plast, og at mindst én markeringslinie har gennemsigtige områder på en sådan måde, at farveforrådet, dvs. stillingen af efterløbsstemplet, kan iagttages gennem viseråbnin-20 gen i skabelontrykkemaskinen foruden farveafgangsåbningernes indstilling.This object is met by the fact that the color container is made of plastic and that at least one marking line has transparent areas in such a way that the color supply, ie. The position of the post-stamp can be observed through the display aperture of the template printing machine in addition to the setting of the color discharge openings.

En særlig billig måde til at fremstille markeringslinierne med gennemsigtige områder er angivet i den kendetegnende del af krav 2, medens det i den kendetegnende del af krav 3 anfør-25 te sikrer, at der i viseråbningen klart fremtræder en far-veskillelinie mellem trykfarven, stemplet og det tomme rum bag ved stemplet.A particularly inexpensive way of producing the marking lines with transparent areas is indicated in the characterizing part of claim 2, while it is stated in the characterizing part of claim 3 that a color separating line between the ink, stamped and and the empty space behind the piston.

Ved at farvebeholderen ifølge det i den kendetegnende del af krav 4 anførte ved sin mod bunden vendende ende har en 30 ringnot, får man en til fremstilling af farvebeholderen ifølge opfindelsen særlig egnet form, idet man ved fremstillingen i ringnoten kan indføre en tang, der trækker farvebeholderen ud af sprøjteværktøjet således, at man på enkel måde 3 142229 får fremstillet en beholder med en lille konicitet for den indre væg, hvilket sikrer en dadelfri funktion for efterløbs-stemplet. Uden denne enkle og billige mulighed til fremstilling af beholderen ville man ikke kunne sikre, at efterløbs-5 stemplet fulgte trykfarven umiddelbart under dennes udtømning, hvilket ville forringe muligheden for på enkel og hurtig måde at kontrollere farveforrådet.In that the color container according to the characterizing part of claim 4, at its end facing the bottom, has a ring groove, one obtains a particularly suitable shape for the manufacture of the color container according to the invention, since in the manufacture of the ring groove one can introduce a pliers which pull the color container out of the spraying tool so that a container with a small conicity for the inner wall is produced in a simple manner, which ensures a smooth operation for the post-stamp. Without this simple and inexpensive option for manufacturing the container, it would not be possible to ensure that the aftermarket stamp followed the ink immediately during its discharge, which would impair the ability to control the ink supply in a simple and quick manner.

De ved opfindelsen opnåelige fordele består især deri, at ved siden af indstillingen af farveafgangsåbningerne også det i 10 farvebeholderen værende farveforråd kan kontrolleres enkelt og hurtigt, og at en af plast fremstillet farvebeholder er billigere end en aluminiumsbeholder.The advantages of the invention in particular consist in the fact that, in addition to the setting of the color discharge openings, the color supply in the color container can be controlled simply and quickly, and that a color-made plastic container is cheaper than an aluminum container.

Et udførelseseksempel for opfindelsen er vist på tegningen og beskrives nærmere nedenfor. På tegningen viser 15 fig. 1 en farvebeholder ifølge opfindelsen set fra siden og fig. 2 et snit igennem beholderen ifølge fig. 1.An embodiment of the invention is shown in the drawing and is described in more detail below. In the drawing, FIG. 1 is a side view of a color container according to the invention; and FIG. 2 is a section through the container of FIG. First

På tegningen er med 1 betegnet en af plast, fortrinsvis af polyethylen eller polypropylen, sprøjtestøbt farvebeholder ifølge opfindelsen, som på sin kappeflade har påtrykt mar-20 keringslinier 2 og 3, som tjener til at vise den øjeblikkelige indstilling for farveudtrædningsåbningerne for den på tegningen ikke viste farvetilføringsindretning for en skabelontrykkemaskine. De retlinet forløbende markeringslinier 2 har to gennemsigtige områder 4, i hvilke et efterløbsstempel 5 25 samt farveforrådet kan iagttages. Herved opnås, at i d6**1 på tegningen ikke viste viseråbning i skabelontrykkemaskinen er såvel indstillingen af farveudtrædningsåbningen som farveforrådet samtidig kontrollerbart med et enkelt blik.In the drawing, 1 is designated a plastic, preferably of polyethylene or polypropylene, injection molded paint container according to the invention, which has printed on its casing marking lines 2 and 3, which serve to show the instantaneous color exit apertures for the one in the drawing. illustrated a color printing device for a template printing machine. The rectilinear gradient marking lines 2 have two transparent areas 4 in which a postmark 5 and the color stock can be observed. Hereby it is achieved that in d6 ** 1 in the drawing, the display opening shown in the template printing machine, both the setting of the color exit opening and the color supply are simultaneously controllable with a single glance.

Efterløbsstemplet 5, der til bedre synlighed kan være farvet, 30 ligger tætnende an imod beholderens indervæg 6.The aftermarking piston 5, which may be colored for better visibility, 30 seals sealingly against the inner wall 6 of the container.
