Opfindelsen angår et apparat til adskilt optagelse af to materialer,og ved hjælp af hvilket de to materialer før deres anvendelse lader sig blande og derpå afgive, og af den i indledningen til patentkrav 1 angivne art.BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to an apparatus for separating two materials separately, by means of which the two materials can be mixed and then dispensed prior to their use, and of the kind specified in the preamble of claim 1.
5 Ved et kendt apparat af denne art (beskrivelsen til USA5 By a known apparatus of this kind (description to the United States
patent nr.3.153.531) er blandestemplet før apparatets anvendelse anbragt tilnærmelsesvis ved midten af den rørformede beholder og er overdækket med et folieark, der danner en membranlignende skillevæg, som opdeler beholderens indre i to 10 afdelinger til de to materialer. Et aftageligt udvendigt klem-mebånd indsnører den rørformede beholder lidt for at holde både folieskillevæggen og blandestemplet i disses udgangsstillinger. Den aksialt forskydelige betjeningsstang er med sin indre ende på udløselig måde sammenskruet med blandestemp-15 let og forløber ud gennem beholderens udleveringsåbning og tjener til at begynde med til at lukke denne.Patent No. 3,153,531), prior to use of the apparatus, the mixing piston is positioned approximately at the center of the tubular container and is covered with a film sheet forming a membrane-like partition dividing the interior of the container into two compartments for the two materials. A removable outer clamping band slightly inclines the tubular container to hold both the foil partition and the mixing piston in their initial positions. The axially displaceable operating rod is, with its inner end, releasably screwed together with the mixing plunger and extends through the dispensing opening of the container and serves initially to close it.
Efter fjernelse af det udvendige klemmebånd kan man bevæge blandestemplet frem og tilbage i den rørformede beholder ved hjælp af betjeningsstangen til sammenblanding af de to materia-20 ler, hvorved foliearket trykkes bort fra blandestemplets bevægelsesbane og mod indersiden af udpresningsstemplet, som lukker den anden ende af beholderen. Når blandingen af de to materialer er afsluttet, skrues betjeningsstangen ud af blandestemplet og trækkes ud gennem beholderens udleveringsåbning 25 for at frigive denne åbning til udpresning af de sammenblandede materialer. Før udpresningen imidlertid begynder, anbringes der en fordelerdyse eller et mundstykke ved udleveringsåbningen, hvorpå bagsiden af udpresningsstemplet påvirkes med trykluft for at presse de blandede materialer ud. Anvendelsen 30 af dette apparat kræver følgelig ikke alene en trykluftkilde, men også en fuldstændig fjernelse af betjeningsstangen fra beholderen samt en derpå følgende fastgørelse af et mundstykke til beholderens udleveringsåbning.After removing the outer clamping tape, the mixing piston can be moved back and forth in the tubular container by means of the operating rod for mixing the two materials, thereby pushing the sheet of film away from the movement of the mixing piston and towards the inside of the pressing piston which closes the other end of the container. When the mixing of the two materials is completed, the control rod is unscrewed from the mixing plunger and pulled out through the dispensing opening 25 of the container to release this opening to extrude the blended materials. However, before the pressing begins, a distributor nozzle or nozzle is placed at the dispensing opening, whereupon the back of the pressing piston is actuated with compressed air to extrude the mixed materials. Accordingly, the use of this apparatus requires not only a source of compressed air, but also a complete removal of the operating rod from the container and a subsequent attachment of a nozzle to the dispensing opening of the container.
Ved et lignende kendt apparat (beskrivelsen til USA patent 35 nr. 3.144.966) er den med blandestemplet sammenskruelige,aksialt forskydelige betjeningsstang hul for optagelse af et af de to materialer, der skal blandes. Med dette formål for øje er den hule betjeningsstang lukket ved den ene ende ved hjælp af 142696 2 et ved hjælp af en støder forskydeligt stempel og er lukket ved den anden ende ved hjælp af en oprivelig membran, som kan oprives ved hjælp af en på indersiden af udpresningsstemplet anbragt kegleformet spids. Også i dette tilfælde betjenes ud-5 presningsstemplet ved hjælp af trykluft, men forud herfor skal betjeningsstangen fjernes, og der skal ved udleveringsåbningen anbringes et mundstykke. Dette kendte apparat er derfor forbundet med de samme mangler som omtalt i det foregående.In a similarly known apparatus (US Patent Specification No. 3,144,966), the axially screwable axially displaceable control rod is hollow for receiving one of the two materials to be mixed. For this purpose, the hollow control rod is closed at one end by means of a piston displaceable piston and is closed at the other end by a peelable diaphragm which can be torn up by means of an inner surface. of cone-shaped plunger tip. In this case, too, the extruder piston is operated by compressed air, but before this the control rod must be removed and a nozzle must be placed at the dispensing opening. This known apparatus is therefore associated with the same shortcomings as mentioned above.
Endvidere kendes der talrige apparater til sammenblanding 10 af to materialer og derpå følgende afgivelse af disse, og der skal i denne forbindelse henvises til beskrivelserne til USA patenterne nr. 3.188.056, 3.188.057, 3.197.067 og 3.376.999, som er forsynet med en beholder, der ved den ene ende har en udleveringsåbning og ved den anden ende har et manuelt bevæge-15 ligt udpresningsstempel. Til blanding og afgivelse af de blandede materialer kræves der imidlertid ved disse apparater en ommontering af betjeningsstangen, eller man benytter i disse tilfælde to forskellige betjeningselementer til blande- og udpresningsstemplerne. Disse kendte apparater er derfor omstænde-20 lige at betjene.Furthermore, numerous apparatus for mixing 10 materials and their subsequent release are known, and reference should be made in this connection to U.S. Patents Nos. 3,188,056, 3,188,057, 3,197,067, and 3,376,999, which are provided with a container having at one end a dispensing opening and at the other end having a manually movable extruder piston. However, for mixing and dispensing of the mixed materials, these devices require a reassembly of the control rod, or two different control elements are used for the mixing and pressing pistons in these cases. These known devices are therefore easy to operate.
Et yderligere kendt apparat (USA patentskrift nr.3.140.078) anvender til blanding og afgivelse et todeleligt stempel, som kan bevæges frem og tilbage inde i beholderen ved hjælp af en i beholderens bageste endeside forskydeligt lejret betje-25 ningsstang. Stemplets enkelte dele skal imidlertid til tilvejebringelse af afgivelsesoperationen drejes i forhold til hinanden for at opnå en lukket stempelendeflade, hvilket imidlertid forhindres af de blandede materialer, som ved den relative drejning forskyder sig mellem stempeldelene.A further known apparatus (US Patent No. 3,140,078) uses for mixing and dispensing a two-part piston which can be moved back and forth inside the container by means of a control rod which is displaceably displaced in the rear end side of the container. However, in order to provide the dispensing operation, the individual parts of the piston must be rotated relative to each other to obtain a closed piston end surface, which is prevented, however, by the mixed materials which, in the relative rotation, shift between the piston parts.
30 Ved et yderligere kendt apparat til adskilt optagelse af to materialer og derefter følgende blanding og afgivelse af disse anvendes der også kun et betjeningsstempel, der imidlertid kun ved hjælp af et enkelt slag tilvejebringer blandingen af materialerne og disses afgivelse, hvorved det i praksis 35 ikke er muligt at opnå en grundig blanding af de to materialer.30 In a further known apparatus for separating uptake of two materials and then mixing and dispensing them, only an actuating piston is used, which, however, only provides, by means of a single stroke, the mixing of the materials and their delivery, whereby in practice it does not is possible to obtain a thorough mixing of the two materials.
Det er formålet med den foreliggende opfindelse at forbedre et apparat af den i indledningen til patentkrav 1 angivne art på en sådan måde, at udpresningen kan tilvejebringes manuelt 142696 3 ved hjælp af den til blandingen anvendte betjeningsstang uden nogen ommontering af betjeningsstangen, og dette opnås ifølge opfindelsen ved hjælp af de i patentkrav l's kendetegnende del angivne foranstaltninger. Herved opnås det, at en ommonte-5 ring af betjeningsstangen er overflødig, således at blandingen af de to materialer og disses udpresning kan ske i løbet af forholdsvis kort tid. Ved anvendelse af apparatet udfører betjeningsstangen fire efter hinanden følgende funktioner. Først indskydes betjeningsstangen i beholderen for at oprive skil-10 levæggen. Derefter forbindes den indre ende af betjeningsstangen med blandestemplet, således at man kan trække blandestemplet tilbage for at føre den oprevne skillevæg bort fra blandestemplets bevægelsesbane og trykke den mod det tilbagetrukne udpresningsstempel. Derefter bevæges betjeningsstangen frem og tilbage 15 for ved hjælp af blandestemplet at blande de to materialer grundigt. Slutteligt trækkes betjeningsstangen tilbage, således at den oprevne skillevæg indklemmes mellem blandestemplet og udpresningsstemplet,og derpå forbindes den tilbagetrukne betjeningsstang med udpresningsstemplet ved hjælp af det bøsninge-20 formede forbindelseselement for udpresning af blandingen.It is the object of the present invention to improve an apparatus of the kind set forth in the preamble of claim 1 in such a way that the extruder can be provided manually by means of the control rod used for the mixture without any remounting of the control rod and this is achieved according to the invention. the invention by means of the features specified in the characterizing part of claim 1. Hereby it is achieved that a remounting of the control rod is superfluous, so that the mixing of the two materials and their extruding can take place in a relatively short time. When using the appliance, the control bar performs four consecutive functions. First, the control rod is inserted into the container to tear the dividing wall. Then, the inner end of the control rod is connected to the mixing plunger so that the mixing plunger can be retracted to guide the torn partition away from the movement path of the mixing plunger and press it against the retracted pressing plunger. Then the control rod is moved back and forth 15 to thoroughly mix the two materials by means of the mixing piston. Finally, the control rod is retracted so that the torn partition is squeezed between the mixing piston and the pressing plunger, and then the retracted control rod is connected to the pressing plunger by means of the bush-shaped connecting element for pressing the mixing.
Ved hjælp af den i patentkrav 2 angivne udførelsesform opnås det, at det aksialt forskydelige forbindelseselement kan sammenlåses med forbindelsesstangen på meget simpel måde, nemlig blot ved aksial forskydning af forbindelseselementet, 25 indtil fingeren indgriber i rillen.By the embodiment of claim 2, it is achieved that the axially displaceable connecting element can be interlocked with the connecting rod in a very simple way, namely simply by axially displacing the connecting element, until the finger engages the groove.
Opfindelsen skal herefter forklares nærmere under henvisning til tegningen, hvor fig. 1 viser et længdesnit gennem en udførelsesform for apparatet ifølge opfindelsen til belysning af en 30 udleveringspatron, som tjener som beholder for to adskilte materialer, fig. 2 et perspektivisk billede af et blandestempel til apparatet uden membranlignende skillevæg, fig. 3 et billede i lighed med fig. 2, men hvor en mem-35 branlignende skillevæg er svøbt over bagsiden af blandestemplet, fig. 4 et snit gennem den forreste del af patronen til belysning af en dyse, der samtidig virker som ventil for patronens udleveringsåbning, 4 162696 fig. 5 i forstørret målestok et perspektivisk billede af en fjernelig låseklemme, som kan anvendes til at holde dysen i dennes forreste lukkede stilling, indtil tidspunktet for patronens anvendelse, ^ fig. 6 en del af et længdesnit til belysning af, hvorledes blandestemplet kan trækkes tilbage til bevægelse af den sønderrevne membranlignende skillevæg ud af vejen mod et tilbagetrukket udpresningsstempel, fig. 7 et tilsvarende billede til belysning af, hvorledes 10 blandestemplet kan bevæges frem og tilbage til blanding af materialerne, fig. 8 et tilsvarende billede til belysning af blandestemplet trukket tilbage mod udpresningsstemplet, og som yderligere belyser en betjeningsstang forbundet 15 med udpresningsstemplet parat til en udleverings operation , og fig. 9 en del af et billede i lighed med fig. 4 til belysning af en ændring af dysen til udleveringspatronen.The invention will now be explained in more detail with reference to the drawing, in which fig. 1 is a longitudinal section through an embodiment of the apparatus according to the invention for illuminating a dispensing cartridge serving as a container for two separate materials; FIG. 2 is a perspective view of a mixing piston for the apparatus without membrane-like partitions; FIG. 3 is a view similar to FIG. 2, but where a membrane-like partition is wrapped over the back of the mixing piston; FIG. 4 is a section through the front part of the cartridge to illuminate a nozzle which simultaneously acts as a valve for the delivery port of the cartridge; FIG.

Tegningen viser den for tiden foretrukne udførelsesform for 2° apparatet ifølge opfindelsen i form af en udleveringspatron til éngangsbrug, der som helhed er betegnet med 10, og som er beregnet til at indeholde f.eks. et tætningsmateriale, som tilberedes til det tidspunkt, hvor det skal anvendes, ved at blande et basismateriale med en katalysator eller accelerator.The drawing shows the presently preferred embodiment of the 2 ° apparatus according to the invention in the form of a single use dispensing cartridge, which is generally designated 10, and which is intended to contain e.g. a sealing material which is prepared to the time of use by mixing a base material with a catalyst or accelerator.
25 Et sådant tætningsmiddel fås i handelen under varemærket Thiokol. Det vil naturligvis forstås, at patronen kan anvendes til blanding af andre materialer til andre formål.25 Such a sealant is commercially available under the trademark Thiokol. Of course, it will be appreciated that the cartridge can be used for mixing other materials for other purposes.
Hoveddelene af patronen omfatter: en tyndvægget cylindrisk beholder 12, der hensigtsmæssigt er fremstillet af et passende 20 formstof, f.eks. polyethylen, hvilken beholder er åben ved den ene ende og ved den anden ende er udformet med en hals, som danner en forreste udleveringsåbning 42, et bevægeligt udpresningsstempel 15 til ekstrudering af patronens indhold ud gennem udleveringsåbningen, en passende dyse 16, gennem hvilken blandin-25 g en skal udleveres, et blandestempel 18 til blanding af de to materialer umiddelbart forud for udleveringsoperstionen, en gennembrydelig membranlignende skillevæg 20, som er bægerformet til omslutning af blandestemplet 18 for at tjene som en skillevæg til deling af patronen i en første forreste afdeling 22 til 142696 5 optagelse af et af materialerne, f.eks. et basismateriale, og en bageste afdeling 24 til optagelse af et andet materiale, f.eks. en katalysator eller accelerator til basismateriale, samt en betjeningsstang 26, som er beregnet til at tjene til 5 gennembrydning af den gennembrydelige membran 20, til bevægelse af blandestemplet 18 frem og tilbage til blanding af de to materialer, samt til påvirkning af udpresningsstemplet 15 til ekstrudering af blandingen ud* gennem dysen 16.The main parts of the cartridge include: a thin-walled cylindrical container 12 conveniently made of a suitable resin, e.g. polyethylene, which is open at one end and formed at the other end with a neck forming a front dispensing opening 42, a movable extruder 15 for extruding the contents of the cartridge out through the dispensing opening, a suitable nozzle 16 through which 25 g of a shell, a mixing plunger 18 for mixing the two materials immediately prior to the dispensing operation, is provided, a permeable membrane-like partition 20 which is cup-shaped to enclose the mixing plunger 18 to serve as a partition for dividing the cartridge into a first front section 22 for recording one of the materials, e.g. a base material, and a rear section 24 for receiving another material, e.g. a base material catalyst or accelerator, and a control rod 26 intended to serve to pierce the permeable membrane 20, to move the mixing piston 18 back and forth to mix the two materials, and to actuate the extrusion piston 15 for extrusion of the mixture out * through the nozzle 16.
Bagenden af beholderen 12 er forsynet med en ring 28, hvori 10 der findes en aksial åbning 30, hvis kant går klar af betjeningsstangen 26, og formålet med denne ring er at forstærke bagkanten af beholderen og at tjene som stop til forhindring af utilsigtet udtrækning af udpresningsstemplet 15. Betjeningsstangen 26, som er udformet med et håndtag 32, befinder sig 15 til at begynde med i en tilbagetrukket stilling, således som vist i fig. 1 under forsendelse og håndtering af patronen forud for tidspunktet, hvor indholdet skal anvendes. Som vist i fig. 1 omgiver et i længderetningen opslidset kartonrør 34 hensigtsmæssigt betjeningsstangen 26 til at begynde med, og 20 den ene ende af dette opslidsede rør hviler mod udpresningsstemplet 15, og den anden ende hviler mod håndtaget 32 for at forhindre en for tidlig og utilsigtet fremføring af betjeningshåndtaget. Et sådant kartonrør kan let fjernes til anvendelsestidspunktet.The rear end of the container 12 is provided with a ring 28, wherein 10 is provided with an axial opening 30, the edge of which is clear from the operating rod 26, and the purpose of this ring is to reinforce the trailing edge of the container and to serve as a stop to prevent accidental pull-out. the pressing plunger 15. The operating rod 26, which is formed with a handle 32, is initially 15 in a retracted position, as shown in FIG. 1 during shipping and handling of the cartridge prior to the time when the contents are to be used. As shown in FIG. 1, a longitudinally slit cardboard tube 34 conveniently surrounds the operating rod 26 initially, and 20 one end of this slotted tube rests on the pressing piston 15 and the other end rests on the handle 32 to prevent premature and unintended advancement of the operating handle. Such a cardboard tube can easily be removed at the time of use.
25 Udleveringsåbningen, som er forsynet med dysen 16, kan nor malt være lukket på enhver passende måde. I denne særlige udførelsesform for apparatet ifølge opfindelsen virker dysen 16 som et ventilorgan, der er bevægeligt mellem den i fig. 1 viste lukkede stilling og en tilbagetrukket stilling, som er vist med 30 punkterede linier i fig. 4. Dysen 16 kan være indrettet til forbindelse med en bøjelig udleveringsslange eller -rør (ikke vist) og kan med dette formål for øje være forsynet med en række bagud hældende, skarpe ribber 35, der tjener som kanter til indgreb med den bøjelige slanges inderside.The dispensing aperture provided with the nozzle 16 can normally be closed in any suitable manner. In this particular embodiment of the apparatus according to the invention, the nozzle 16 acts as a valve member movable between the one shown in FIG. 1 and a retracted position shown by 30 dashed lines in FIG. 4. The nozzle 16 may be arranged for connection to a flexible delivery hose or tube (not shown) and may for this purpose be provided with a series of backwardly sloping sharp ribs 35 which serve as edges for engagement with the inside of the flexible hose. .
35 Dysen 16 er lukket ved sin inderende ved hjælp af en tværgå ende væg 36 og er yderligere forsynet med en radial flange 38 ved sin bagende, hvilken flange normalt hviler mod bagenden af udleveringsåbningen, således som vist i fig. 1. Dysen 16 er 6 142696 yderligere forsynet med radiale porte 40, som normalt er lukket af indersiden 42 af udleveringsåbningen. En væsentlig del af dysen 16 rager ud foran udleveringsåbningen, og denne forreste del er udformet med et bagud vendende, rundgående bryst 44, 5 der tjener som stop ved anlæg mod kanten af udleveringsåbningen i dysens tilbagetrukne, åbne stilling. I den tilbagetrukne, åbne stilling af dysen kan patronens indhold strømme frit gennem de radiale porte 40 ind i og gennem dysen.The nozzle 16 is closed at its inner end by a transverse end wall 36 and is further provided with a radial flange 38 at its rear end, which flange normally rests against the rear end of the dispensing opening, as shown in FIG. 1. The nozzle 16 is further provided with radial ports 40, which are normally closed by the inside 42 of the dispensing opening. A substantial portion of the nozzle 16 protrudes in front of the dispensing opening, and this front portion is formed with a rearwardly facing, rounded chest 44, 5 which serves as a stop when abutting against the edge of the dispensing opening in the retracted open position of the nozzle. In the retracted, open position of the nozzle, the contents of the cartridge can flow freely through the radial ports 40 into and through the nozzle.
Som vist i fig. 1 er dysen 16 låset i sin forreste lukkede 10 stilling ved hjælp af en låseklemme 45, når patronen håndteres og opbevares samt forsendes forud for anvendelsen, og denne låseklemme er indskudt mellem brystet 44 på dysen og den forreste kant af udleveringsåbningen. Således som det tydeligt fremgår af fig. 5, har låseklemmen 45 en krum hoveddel 46, der er dimen-15 sioneret således, at den strækker sig mere end halvvejs rundt om dysen 16. Låseklemmen er fremstillet af et tilstrækkeligt elastisk formstofmateriale til eftergivende at gribe omkring dysen på aftagelig måde, og klemmen er udformet med en med ribber forsynet flig 48, der tjener som et passende håndgreb ved 20 klemmens fjernelse.As shown in FIG. 1, the nozzle 16 is locked in its front closed position by a locking clamp 45 when the cartridge is handled and stored and shipped prior to use, and this locking clip is inserted between the chest 44 of the nozzle and the leading edge of the dispensing opening. As can be seen clearly in FIG. 5, the locking clamp 45 has a curved body 46 dimensioned such that it extends more than halfway around the nozzle 16. The locking clamp is made of a sufficiently resilient plastic material to resiliently engage the nozzle in a removable manner and the clamp is formed with a ribbed tab 48 which serves as a suitable handle on the removal of the clamp.
Som det tydeligt fremgår af fig. 2, har blandestemplet 18 en midterste navdel 50, en cylindrisk omkredsdel 52 samt to åbninger 54 i to af sine kvadranter, og den resterende halvdel af blandestemplet er lukket. Blandestemplet 18 er beregnet til 25 udløselig forbindelse med betjeningsstangen 26, og med dette formål for øje kan navdelen 50 være forsynet med et indvendigt gevind 56 til sammenskruning med et udvendigt gevind 58 på betjeningsstangens forende.As can be seen clearly in FIG. 2, the mixing piston 18 has a middle hub portion 50, a cylindrical circumferential portion 52, and two openings 54 in two of its quadrants, and the remaining half of the mixing piston is closed. The mixing piston 18 is intended for releasable connection with the actuating rod 26, and for this purpose the hub portion 50 may be provided with an internal thread 56 for screwing in with an external thread 58 on the front end of the actuating rod.
Ved den viste udførelsesform for apparatet ifølge opfindel-30 sen er den deformerbare eller sønderrivelige membran 20, der udgøres af et cirkulært ark af aluminiumfolie, svøbt over bagsiden af blandestemplet 18. Metalfolien dækker således bagsiden af blandestemplet og er forsynet med en cylindrisk omkredsflange eller kantdel 60, som tæt omslutter den cylindriske 35 omkredsdel 52 af blandestemplet. Blandestemplet 18 tjener således til at begynde med som organ i indgreb med folien 20 til at understøtte folien og at samvirke med den omgivende beholder 12 til gribning af foliens omkredsflange 60 på tæt måde.In the illustrated embodiment of the apparatus according to the invention, the deformable or tear diaphragm 20, which is formed of a circular sheet of aluminum foil, is wrapped over the back of the mixing piston 18. The metal foil thus covers the back of the mixing piston and is provided with a cylindrical circumferential flange or edge part. 60, which closely surrounds the cylindrical circumference portion 52 of the mixing piston. Thus, initially, the mixing piston 18 serves as a means for engaging the foil 20 to support the foil and to cooperate with the surrounding container 12 for gripping the circumferential flange 60 of the foil in a tight manner.
Det påtænkes at anbringe passende organer til ubevægelig- 7 142696 gørelse af det med skillevæg forsynede blandestempel 18 til at begynde med i en mellemstilling, i hvilken det opdeler beholderen i den tidligere omtalte forreste og bageste afdeling, henholdsvis 22 og 24 til adskilt opbevaring af de to materialer. Sådanne 5 organer til ubevægeliggørelse af blandestemplet kan omfatte organer, som omslutter den elastiske beholder 12, og som indsmører denne, således at denne klemmer omkredsflangen 60 af folien mod omkredsfladen af beholderen. Enhver passende form for omsluttende organ kan anvendes til dette formål. Ved den 10 viste udførelsesform for apparatet ifølge opfindelsen er et passende stykke klæbebånd 62 viklet omkring beholderen 12 med tilstrækkelig stramhed til fastklemning af blandestemplet 18 i dennes stilling med omkredsflangen 60 af folien 20 grebet på tæt måde.It is contemplated to provide suitable means for moving the partitioned mixing piston 18 initially to an intermediate position in which it divides the container into the aforementioned front and rear compartments 22 and 24 respectively for separate storage of the two materials. Such means for moving the mixing piston to move can comprise means which enclose the resilient container 12 and which lubricate it so that it clamps the circumferential flange 60 of the foil against the circumferential surface of the container. Any suitable type of enclosing means may be used for this purpose. In the embodiment of the apparatus according to the invention shown, a suitable piece of adhesive tape 62 is wound around the container 12 with sufficient tightness to clamp the mixing piston 18 in its position with the circumferential flange 60 of the foil 20 tightly gripped.
15 Med betjeningsstangen 26 normalt tilbagetrukket og sikret ved hjælp af det opslidsede kartonrør 34, som vist i fig. 1, og med klæbebåndet 62, som ubevægeliggør blandestempiet i en mellemstilling, kan det opslidsede kartonrør 34 fjernes til tidspunktet for anvendelsen for at tillade betjeningsstangen at 20 blive skudt frem med det dobbelte formål for øje at sønderrive membranen 20 og tilvejebringe indgreb med blandestemplet 18. Hensigtsmæssigt er membranens gennemtrængning lettet ved at forsyne forenden af betjeningsstangen med en skarp spids 64. Den spidse ende af betjeningsstangen skydes gennem membranen til 25 sønderrivning af denne, og betjeningsstangen skydes derefter yderligere frem og drejes for at blive skruet ind i blandestemplet 18's navdel 50.With the operating rod 26 normally retracted and secured by the slotted cardboard tube 34, as shown in FIG. 1, and with the adhesive tape 62 which moves the mixing piston in an intermediate position, the slotted cardboard tube 34 can be removed to the point of use to allow the operating rod 20 to be pushed forward for the dual purpose of tearing the diaphragm 20 and engaging the mixing piston 18. Conveniently, the penetration of the diaphragm is facilitated by providing the front end of the control rod with a sharp tip 64. The pointed end of the control rod is slid through the diaphragm to tear it, and the control rod is then further advanced and rotated to be screwed into the hub portion 50 of the mixing rod 18.
Nu kan klæbebåndet 62 fjernes for frigivelse af blandestemplet, og derefter kan betjeningsstangen trækkes tilbage til 30 forskydning af den sønderrevne membran bagud mod udpresningsstemplet 15, således som vist i fig. 6. Denne tilbagetrækning af blandestemplet er gjort mulig i kraft af, at materialet i afdelingen 24 nu har frihed til at strømme gennem membranens sønderrevne åbning og gennem blandestemplets to åbninger 54.Now the adhesive tape 62 can be removed for release of the mixing piston, and then the operating rod can be retracted for displacement of the tear-torn diaphragm backward against the extruder piston 15, as shown in FIG. 6. This withdrawal of the mixing piston is made possible by the fact that the material in the compartment 24 now has the freedom to flow through the tear-opening of the membrane and through the two openings 54 of the mixing piston.
35 Når folien 20 er trukket helt tilbage mod udpresningsstemp let 15, kan blandestemplet bevæges fremefter til udrykning af dette fra folien, og derefter kan blandestemplet bevæges frem og tilbage ved hjælp af betjeningsstangel) således som antydet i fig. 7 til blanding af de to materialer. Hvis folien 142696 8 skulle have tendens til at klæbe fast til blandestemplet, vil folien til sidst blive udrykket ved en af blandestemplets tilbagegående bevægelser.When the foil 20 is fully retracted towards the pressing plunger 15, the mixing piston can be moved forward to extend it from the foil, and then the mixing piston can be moved back and forth by means of the operating rod) as indicated in FIG. 7 for mixing the two materials. If the foil 142696 8 tends to adhere to the mixing plunger, the foil will eventually be elongated by one of the reciprocating movements of the mixing plunger.
Skønt betjeningsstangen 26 til at begynde med er forskyde-5 ligt anbragt i udpresningsstemplet 15 for udøvelse af blandeope-rationen, kan betjeningsstangen dog derefter forbindes arbejdsmæssigt med udpresningsstemplet for bevægelse af dette fremefter til ekstrudering af blandingen ud gennem dysen 16. For tilvejebringelse af denne sluttelige forbindelse mellem betjeningsstan-10 gen 26 og udpresningsstemplet er forenden af betjeningsstangen forsynet med en radial flange 65, og betjeningsstangen er yderligere udformet med en rundgående rille 66 til samvirkning med et bøsningeformet forbindelseselement 68, der til at begynde med er trukket tilbage til udpresningsstangens yderende, 15 således som vist i fig. 1. Forbindelseselementet 68 kan være fremstillet af et passende elastisk formstof og er udformet med en indadvendende radial flange 70 ved sin forende til indgreb med den rundgående rille 66. Således som vist i fig. 1 er forenden af forbindelseselementet 68 udformet med en række slidser, 20 som danner elastiske låsefingre 72.However, although initially the actuating rod 26 is slidably disposed in the extruder piston 15 for performing the mixing operation, the actuating rod may then be operatively connected to the extruder piston for moving it forward to extrude the mixture out through the nozzle 16. To provide this final connecting the actuating rod 26 to the extruder piston, the front end of the actuating rod is provided with a radial flange 65, and the actuating rod is further provided with a circular groove 66 for cooperating with a sleeve connecting member 68 which is initially retracted to the outer end of the extruder rod; 15 as shown in FIG. 1. The connecting member 68 may be made of a suitable resilient plastic and is formed with an inwardly extending radial flange 70 at its front end for engagement with the circular groove 66. As shown in FIG. 1, the front end of the connecting member 68 is formed with a series of slots 20 forming elastic locking fingers 72.
Efter at blandingsoperationen er udført på den i fig. 7 antydede måde, kan betjeningsstangen trækkes tilbage til indeslutning af den sønderrevne folie 20 mød udpresningsstemplet 15 og til anbringelse af betjeningsstangens flange 65 i anlæg mod 25 forsiden af udpresningsstemplet. I denne stilling af betjeningsstangen i forhold til udpresningsstemplet er den rundgående rille 66 blottet bagved en navdel 74 på udpresningsstemplet for at tillade, at forbindelseselementet 68 skydes frem til indgreb med den rundgående rille. Med forbindelseselementets inderflange 30 74 anbragt i rillen, således som vist i fig. 9, er udpresnings stemplet 15 fastlåset mellem forbindelseselementet og betjeningsstangens forreste flange 65, og udpresningsstemplet kan skydes manuelt frem ved hjælp af betjeningsstangen til ekstrudering af blandingen fra patronen.After the mixing operation is performed on the one shown in FIG. 7, the actuating rod may be retracted to enclose the tear-off foil 20 meeting the extruder piston 15 and to affix the actuating rod flange 65 to abut the front face of the extruder piston. In this position of the actuating rod relative to the extruder piston, the circular groove 66 is devoid of a hub portion 74 of the extruder piston to allow the connecting member 68 to slide forward into engagement with the circular groove. With the inner flange 30 74 of the connecting element placed in the groove, as shown in FIG. 9, the squeeze plunger 15 is locked between the connecting member and the front flange 65 of the control rod, and the squeeze plunger can be manually pushed forward by the control rod for extrusion of the mixture from the cartridge.
35 Det er vigtigt at bemærke, at blandestemplet 18 under ekstru- deringsoperationen samvirker med udpresningsstemplet 15 til effektiv indeslutning af den sønderrevne folie og til at forhindre, at den sønderrevne folie når frem til dysen 16, hvor den ville kunne forhindre udleveringsoperationen.It is important to note that during extrusion operation, the mixing piston 18 cooperates with the extruding piston 15 to effectively enclose the torn tear film and prevent the tear tipped film from reaching the nozzle 16 where it could prevent the dispensing operation.

Den måde, på hvilken opfindelsen tjener sft formål, vil let forstås af den foregående beskrivelse. Under blandeopera-tionen er dysen 16 fastholdt i sin normale, forreste lukkede stilling ved hjælp af låseklemmen 45, således som vist i 5 fig. 1. Efter blandeoperationen, og efter at udpresningsstemplet er blevet sammenkoblet med betjeningsstangen 26 ved hjælp af forbindelseselementet 68, kan låseklemmen 45 fjernes for at tillade manuel tilbagetrækning af udleveringsdy^en 16 til dennes åbne stilling, således at patronens indhold kan ekstrude-10 res ud gennem dysen ved manuel fremskydning af udpresningsstemp let.The manner in which the invention serves a purpose will be readily understood by the foregoing description. During the mixing operation, the nozzle 16 is held in its normal forward closed position by the locking clamp 45, as shown in FIG. 1. After the mixing operation, and after the extruder piston has been coupled to the actuating rod 26 by the connecting member 68, the locking clamp 45 can be removed to allow manual retraction of the dispensing die 16 to its open position so that the contents of the cartridge can be extruded. through the nozzle by manually pushing the extruder punch lightly.
Til nogle anvendelser af apparatet ifølge opfindelsen kan det være ønskeligt at anvende organer til udløselig fastholdelse af udleveringsdysen 16 i denne tilbagetrukne åbne stilling.For some uses of the apparatus of the invention, it may be desirable to use means for releasably retaining the dispensing nozzle 16 in this retracted open position.
15 F.eks. kan en sådan foranstaltning være ønskelig, hvis den blanding, der skal udleveres, er meget sejg og har tendens til at skyde dysen fremefter under ekstruderingen af blandingen. Fig. 9 viser, hvorledes en dyse 16 kan være forsynet med et udvendigt gevind 75 til samvirkning med et indvendigt gevind 76 20 i udleveringsåbningen. Når det ønskes at åbne dysen, drejes denne simpelthen manuelt, hvorved den trækkes tilbage til sin åbne stilling ved hjælp af skruevirkningen,og denne åbne stilling er vist i fig. 8.For example, such a measure may be desirable if the mixture to be dispensed is very tough and tends to push the nozzle forward during extrusion of the mixture. FIG. 9 shows how a nozzle 16 can be provided with an external thread 75 for cooperation with an internal thread 76 20 in the dispensing opening. When it is desired to open the nozzle, it is simply turned manually, thereby withdrawing it to its open position by means of the screw action, and this open position is shown in FIG. 8th
