Abstract
Description
1 DK 158089 B1 DK 158089 B
Den foreliggende opfindelse angår en aerosolembal1 age af den i krav l's indledning angivne art. En lignende énkammertrykem-ballage med to oven over hinanden stående, via et adaptersystem indbyrdes forbundne aerosoldåser fremgår af beskrivelsen 5 til DE-offentliggørelsesskrift 31 16 282.7 og EP-patentskrift nr. 63759.The present invention relates to an aerosol package of the kind set forth in claim 1. A similar one-chamber pressure package with two superposed superposed aerosol cans via an adapter system is disclosed in the specification 5 of DE Publication No. 31 16 282.7 and EP Patent No. 63759.
Det nedre kammer henholdsvis den nedre dåse optager f.eks. hy-drogenperoxid og drivgas, medens den øvre dåse, henholdsvis 10 det øvre kammer indeholder det pågældende aktive stof, f.eks.The lower chamber and the lower can, respectively, receive e.g. hydrogen peroxide and propellant, while the upper can or the upper chamber, respectively, contain the active substance concerned, e.g.
en alkalisk farvnings- eller affarvningsbasis og er trykfrit.an alkaline staining or decolorizing base and is pressure free.
Ved anvendelse trykkes det nedre kammer mod det øvre kammer. Derved når det nedre kammers indhold i det væsentlige ind i det øvre kammer. Blandingen ledes slutteligt ud via en ventil 15 anbragt ved det øvre kammers hoved.When used, the lower chamber is pressed against the upper chamber. Thereby, the contents of the lower chamber reach substantially into the upper chamber. The mixture is finally discharged via a valve 15 located at the head of the upper chamber.
Overfor bestemte substanser, f.eks. hydrogenperoxid (^C^) har alle hidtil benyttede indre beskyttelseslakker og andre kammerbekladninger vist sig at være ustabile ved langvarig 20 lagring. Man har derfor forsøgt fuldstændigt at forhindre korrosionen ved hjælp af et til aerosolemballagens krav tilpasset pressepakkesystem, dvs. ved at benytte en tokammer-tryk-emballage.For certain substances, e.g. hydrogen peroxide (3 ° C) has all hitherto used internal protective coatings and other chamber coatings found to be unstable in prolonged storage. An attempt has therefore been made to completely prevent the corrosion by means of a press package system adapted to the requirements of the aerosol packaging, ie. by using a two-chamber pressure package.
25 Sådanne tokammer- eller pressepaksystemer beskrives i "aerosol report", bind 20, nr. 5/81, 170-175, og bind 21 nr. 4/82, 172-182, og endvidere i "Seifen-01e-Fette-Wachse" 108. årgang nr. 13/1982, 399/400.Such two chamber or press pack systems are described in "Aerosol Report", Vol. 20, Nos. 5/81, 170-175, and Vol. 21 Nos. 4/82, 172-182, and also in "Seifen-01e-Fette-Wachse" "108th Annual No. 13/1982, 399/400.
30 En sådan fra DE offentliggørelsesskrift 26 59 522 kendt tokam- mer-trykemballage henholdsvis aerosoldåse har en normal 1" åbning for den tilhørende ventil og en ca. 3 mm bred bundåbning, der skal lukkes med en gummiprop. Det i den foreliggende forbindelse væsentlige kendetegn for tokammer-systemet er 35 en indre pose af polyethylen (PE-inderpose), der i ventilåb ningsområdet har en udadtil skørteformet rand, og som, når 230 Such two-chamber pressure packaging or aerosol can as known from DE Publication 26 59 522 has a normal 1 "opening for the associated valve and an approximately 3 mm wide bottom opening to be closed with a rubber stopper. The essential features of the present invention for the two-chamber system, an inner bag is made of polyethylene (PE inner bag) which has in the valve opening area an outwardly skirted rim and which, when 2

den er isat, hviler på dåsens omrullede rand. Den kendte in-derpose har indicerede knæksteder, der ved afgivning af produktet sikrer en styret sammenfoldning og dermed en fuldstændig tømning af posen. Endvidere indeholder venti 1 tallerkenen 5 en "Buna"-tætning. I det ideelle tilfælde klemmes inderposen ved påkrympet ventil mellem "Buna"-tætningen og dåsens omrullede rand.it is inserted, resting on the canned rolled rim. The known inner bag has indicated cracking points which, when delivering the product, ensure a controlled folding and thus a complete emptying of the bag. Furthermore, the venti 1 plate 5 contains a "Buna" seal. In the ideal case, the inner bag is squeezed by a crimped valve between the "Buna" seal and the canned rolled rim.
j0 Den kendte inderpose udfylder kun ca. 2/3 dele af dåsens volumen og indeholder alt det aktive stof. Dåsevolumenets resterende rum fyldes f.eks. ved hjælp af en injektionsnål gennem bundåbningen med drivgas. Sidstnævnte kommer også ved anvendelse ikke i berøring med det aktive stof og ødelægges efter 25 tømning sammen med dåsen.j0 The known inner bag fills only approx. 2/3 parts of the can volume and contains all the active substance. The remaining volume of the can volume is filled e.g. by means of an injection needle through the bottom opening with propellant gas. The latter also does not come into contact with the active substance when used and is destroyed after emptying with the can.
Da inderposen i tokammer-systernet er trykfri og ikke har nogen tætningsfunktion mod det ydre, stilles der ikke nogen særlige tæthedskrav til denne. Når en sådan inderpose isættes til 2q beklædning af det nedre kammer af den indledningsvist omtalte énkammer aerosolemballage, skal inderposen fuldstændigt udfylde det nedre kammer og foruden det nedre kammers aktive stof også indeholde drivgassen. Men når den kendte inderpose vedvarende står under højt tryk, er den sædvanlige tætning 25 af poseranden ved dåsevalseranden ikke altid tilstrækkelig ved prøvning af lagringsevnen. Den på dåsevalseranden liggende poserand kan nemlig, når ventilen sættes på, i det mindste delvis trykkes ind i det nedre kammer. Desuden kan poseranden ved stuk-ningen (tysk: Clinchvorgang) glide ud af tætningsområdet og 3Q i et ekstremt tilfælde ved stukningstangens spredning i det mindste delvis trækkes ind i dåsen. Derved fremkommer der utætheder i ventilområdet, som ikke kan godtages i forbindelse med en inderpose, der står under et højt indre tryk fra en drivgas.Since the inner bag of the two-chamber system is pressure-free and has no sealing function against the exterior, no special tightness requirements are made for it. When such an inner bag is inserted for 2q lining of the lower chamber of the initially mentioned single chamber aerosol packaging, the inner bag must completely fill the lower chamber and, in addition to the lower chamber's active substance, also contain the propellant gas. However, when the known inner bag is continuously under high pressure, the usual sealing 25 of the bag rim at the can roll rim is not always sufficient when testing the storage capacity. Namely, the bag edge lying on the can roll rim, when the valve is fitted, can at least partially be pushed into the lower chamber. In addition, the bag edge at the stitching (German: Clinchvorgang) can slip out of the sealing area and, in an extreme case, at the spreading of the stinging rod, at least partially be drawn into the can. This results in leaks in the valve area which cannot be accepted in connection with an inner bag which is under a high internal pressure from a propellant gas.
Det er den foreliggende opfindelses formål at videreudvikle og forbedre den indledningsvist nævnte étkammer-trykemballage på en sådan måde, at. den også i overtryksområdet og 35 3It is an object of the present invention to further develop and improve the one-chamber pressure package mentioned above in such a way that. it also in the overpressure area and 35 3

med kraftigt korroderende indhold opnår en tilstrækkelig lagerstabilitet.with strong corrosive content achieves sufficient storage stability.
Dette formål tilgodeses ifølge opfindelsen ved, at aerosol-5 emballagen med to over hinanden stående, via et adaptersystem indbyrdes forbundne aerosolkamre er udformet som nærmere angivet i den kendetegnende del af krav 1.This object is met in accordance with the invention in that the aerosol packaging having two superposed, interconnected aerosol chambers is configured as specified in the characterizing part of claim 1.
Opfindelsen består altså i det væsentlige i at anbringe den 10 fra tokammer-trykemballagen kendte inderpose i en étkammer-tryk- emballage og at muliggøre denne overføring ved, at selve inder-posen forsynes med en derpå formet tætningsring, der samtidig gør den ekstra brug af en "Bund1-tætning overflødig. En således udformet inderpose har forarbejdningsteknisk; den fordel, at 15 den plant og godt sikret kan lægges på kammer- henholdsvis dåseranden og ved påsætning af ventillåget skal presses ind i den tilhørende tætningsrille.The invention thus consists essentially of placing the inner bag known from the two-chamber pressure packaging in a one-chamber pressure packaging and enabling this transfer by providing the inner bag itself with a subsequently formed sealing ring, which at the same time makes the additional use of A "bottom1 seal is unnecessary. An inner bag thus designed has processing technique; the advantage that it can be laid flat and well secured on the chamber and can rim respectively and when the valve cover is inserted must be pressed into the corresponding sealing groove.
Fortrinsvis vælges .tætningsringens aksiale tykkelse og radiale 20 bredde stor i forhold til posens vægtykkelser. Til en tætnings ring med en diameter på størrelsesmæssigt 1 mm kommer en bredde af størrelsesmæssigt 3 mm på tale. Selve posen skal bestå af et materiale, der er lagerstabilt over for det aktive stof, der skal fyldes i, også ved langvarig lagring og under 25 stort tryk. Som posemateriale til at lagre fortyndede hydro- genperoxidopløsninger egner sig elastomere af arten polychlo-rophen, polybutadien, chlorbutyl, ethyl/propylterpolymere, fluor-/chlorelastomere, polypropylen, polyethylen.Preferably, the axial thickness and radial width of the sealing ring are chosen relative to the wall thicknesses of the bag. To a sealing ring with a diameter of about 1 mm, a width of about 3 mm is spoken. The bag itself must consist of a material that is stock stable against the active substance to be loaded, also for prolonged storage and under 25 large pressures. As bag material for storing dilute hydrogen peroxide solutions, elastomers of the type polychlorophen, polybutadiene, chlorobutyl, ethyl / propylterene polymers, fluorine / chloro elastomers, polypropylene, polyethylene are suitable.
30 Opfindelsen forklares herefter nærmere under henvisning til tegningen. På denne viser fig. 1 en inderpose, og 35 fig. 2 et længdesnit gennem en aerosolemballage.The invention will now be explained in more detail with reference to the drawing. In this, FIG. 1 is an inner bag, and FIG. 2 is a longitudinal section through an aerosol package.

Fig. 1 viser inderposen 1.FIG. 1 shows the inner bag 1.
Det væsentlige ved denne er den omløbende om poseåbningen 2 ved poseranden udformede tætningsring 3. Denne træder i 5 stedet for en ved pressepaksystemet benyttet udadtil skørte- formet rand. Ved brug anbringes inderposen 1 i det til optagelse af drivgassen og en del af det aktive stof tilvejebragte nedre kammer af aerosolemballagen. Et udførelseseksempel er vist skematisk i fig. 2.Essential to this is the circumferential sealing ring 3 formed around the bag opening 2 at the bag edge, which replaces 5 with an outer skirt-shaped rim used by the press packing system. In use, the inner bag 1 is placed in the lower chamber of the aerosol package for receiving the propellant gas and part of the active substance. An exemplary embodiment is shown schematically in FIG. 2nd

Aerosolemballagen vist i fig. 2 består af en beholder 5, der er sammensat af en øvre part 6 og en nedre part 7, og en kappe 8. I beholderen er der indsat et øvre kammer 9 og et nedre kammer 10. Det øvre kammer 9 har en topventil 11 og en bund-15 ventil 12. Det nedre kammer 10, der almindeligvis forelig ger som en kendt aerosoldåse, har en topventil 13, der funktionsmæssigt korresponderer med det øvre kammer 9's bundventil, som en moder-datterventil af kendt art.The aerosol packaging shown in FIG. 2 consists of a container 5 which is composed of an upper part 6 and a lower part 7, and a jacket 8. An upper chamber 9 and a lower chamber 10 are inserted in the container. The upper chamber 9 has a top valve 11 and a bottom 15 valve 12. The lower chamber 10, which is generally known as a known aerosol can, has a top valve 13 which corresponds functionally with the bottom chamber of the upper chamber 9 as a mother-daughter valve of a known kind.
20 Det i det foreliggende tilfælde væsentlige er det nedre kammer 10's foring med inderposen 1 og indklemningen af den ved poseranden påformede tætningsring 3 mellem det nedre kammer 10's dåsevalse-rand 14 og den til det nedre kammer 10's topventil 13 hørende tætningsrille 15.The essential in the present case is the lining of the lower chamber 10 with the inner bag 1 and the clamping of the sealing ring 3 formed at the bag edge between the canister roller 14 of the lower chamber 10 and the sealing groove 15 of the lower chamber 10.
25 løvrigt anbringes de to produktkamre 9 og 10 fortrinsvis oven over hinanden på en sådan måde, at skaftet af det øvre kammer 9's bundventil 12 sidder centralt over det nedre kammer 10's topventil 13. Ved en mekanisk forskydning af kamrene 9 og 30 10 i forhold til hinanden, f.eks. ved at trykke på en ydre bøjle eller ved hjælp af et bajonetsystem, men også ved hjælp af en skrueforbindelse eller en fortanding, kan det øvre kammer 9 trykkes mod det nedre kammer 10 (eller omvendt). Ved hjælp af den deraf følgende relative bevægelse åbnes moder-dat-35 ter-ventilanordningen 12, 13 og dermed forbindelseskanalen 16 mellem kamrene 9 og 10.25, the two product chambers 9 and 10 are preferably arranged one above the other in such a way that the shaft of the bottom valve 12 of the upper chamber 9 sits centrally over the top valve 13 of the lower chamber 10 in a mechanical displacement of the chambers 9 and 30 10 relative to each other, e.g. By pressing an outer bracket or by means of a bayonet system, but also by means of a screw connection or a tooth, the upper chamber 9 can be pressed against the lower chamber 10 (or vice versa). With the resultant relative movement, the mother-daughter valve assembly 12, 13 and thus the connecting channel 16 between the chambers 9 and 10 are opened.
Det øvre produktkammer 9 kan være udstyret med et eller toThe upper product chamber 9 may be equipped with one or two
