Description

Denne oppfinnelse vedrører en beholder for lagring og transport av små gassmengder under lave overtrykk og bestående av folier som er gasstett forbundet med hinannen langs sine kanter . This invention relates to a container for storing and transporting small quantities of gas under low overpressure and consisting of foils which are gas-tightly connected to each other along their edges.

I mange tilfelle, f.eks. ved prøving av virkemåten av gassanalytiske apparater, demonstrasjon av virkemåten av gassformige medier ved undervisning eller for bekvem prøving av for-skjellige gassformige stoffer med hensyn til hvorvidt de egner seg for de forskjelligste naturvitenskapelige forsøk og målinger, trenges små mengder av en gass eller av en nøyaktig definert gassblanding. I forbindelse med lagring og transport av sådan- In many cases, e.g. when testing the functioning of gas analytical devices, demonstrating the functioning of gaseous media in teaching or for convenient testing of various gaseous substances with regard to whether they are suitable for the most diverse scientific experiments and measurements, small amounts of a gas or of a precisely defined gas mixture. In connection with the storage and transport of such

ne små gassmengder er det kjent å anvende beholdere av metall eller glass. Den slags beholdere er imidlertid Taeheftet med betydelige mangler når det gjelder lagring av små gassmengder. For small amounts of gas, it is known to use containers made of metal or glass. However, this kind of container is Taeheftet with significant shortcomings when it comes to storing small quantities of gas.

På den ene side er det ikke mulig å få tømt disse On the one hand, it is not possible to empty these

stive beholdere fullstendig uten ved anvendelse av særskilte innretninger, da der alltid blir tilbake i beholderen en gass-mengde som er analog med omgivelsens trykk. Av denne grunn er det bare mulig å oppnå en noenlunde økonomisk lagring under høyere overtrykk. I sådanne tilfelle må der imidlertid ved konstruksjonen av beholderne tas hensyn til de tilsvarende sik-kerhetsbestemmelser, hvilket, når det gjelder beholdernes di-mensjonering, fører til store omkostninger. Ennvidere er det for uttak av gassen nødvendig med trykkreduksjonsinnretninger som før uttaket først må evakueres eller spyles med den lagrede gass for unngåelse av forurensning av uttaksproduktet. Alt dette fører til betydelige anstrengelser og omkostninger ved fremstillingen og håndteringen og det nødvendige uttaksutstyr blir vesentlig kostbarere enn det lagrede medium selv. Ennvidere byr det på vanskeligheter å ta ut nøyaktig doserte, små rigid containers completely without the use of special devices, as there is always a quantity of gas left in the container that is analogous to the ambient pressure. For this reason, it is only possible to achieve a reasonably economical storage under higher overpressures. In such cases, however, the construction of the containers must take account of the corresponding safety provisions, which, when it comes to the dimensions of the containers, leads to large costs. Furthermore, for the withdrawal of the gas, pressure reduction devices are required which, before the withdrawal, must first be evacuated or flushed with the stored gas to avoid contamination of the withdrawal product. All this leads to considerable effort and costs in the production and handling, and the necessary extraction equipment becomes significantly more expensive than the stored medium itself. Furthermore, it presents difficulties in taking out accurately dosed, small

gassmengder av"disse beholdere. gas quantities of these containers.

Hensikten med oppfinnelsen er å skaffe en gasslag-ringsbeholder uten disse ulemper, dvs. en sådan hvis fremstil-lingsomkostninger er lave, ved hvilken gassuttaket også for den ukyndige kan skje på enklest mulig måte og hvis lagrede inn-hold kan forbrukes fullstendig. Denne oppgave løses ifølge oppfinnelsen 'ved at en liten del av folien sammenlignet med beholderens totale overflate, er forsterket ved hjelp av et høy-elastisk, gasstett materiale. På det sted hvor den høyelastiske folie befinner seg, kan man ved hjelp av en injeksjonssprøyte-spiss ta ut eh liten mengde gass. The purpose of the invention is to provide a gas storage container without these disadvantages, i.e. one whose manufacturing costs are low, in which the gas withdrawal can also take place in the simplest possible way for the uninitiated and whose stored contents can be completely consumed. According to the invention, this task is solved in that a small part of the foil, compared to the total surface of the container, is reinforced with the help of a highly elastic, gas-tight material. At the place where the highly elastic foil is located, a small amount of gas can be taken out with the help of an injection syringe tip.

Foliene består hensiktsmessig av en kombinasjon av plast- og metallskikt som er fast forbundet med hverandre over hele sin overflate. . Ved hjelp av dette trekk blir beholderens nødvendige grunnelastisitet og dens vekt ikke lenger påvirket på uheldig måte ved tømmingen, men samtidig er beholderens stabilitet så stor at det uten videre er mulig, å sende .den til forbrukeren . både pr. jernbane og pr. post og i.en, lett pakning uten at det byr på noen fare eller komplikasjoner. The foils conveniently consist of a combination of plastic and metal layers which are firmly connected to each other over their entire surface. . With the help of this feature, the necessary basic elasticity of the container and its weight are no longer adversely affected during emptying, but at the same time the stability of the container is so great that it is easily possible to send it to the consumer. both per rail and per post and i.en, light packaging without any danger or complications.

Et utførelseséksempel på oppfinnelsen ér illustrert på tegningen, hvis fig. 1 viser en beholder i tom tilstand, fig. 2 viser et tverrsnitt av en fylt beholder etter linjen II - II på fig. 1, og fig.,3 viser.tilslutningsdelen på en fylt beholder An embodiment of the invention is illustrated in the drawing, if fig. 1 shows a container in an empty state, fig. 2 shows a cross-section of a filled container along the line II - II in fig. 1, and fig. 3 shows the connection part of a filled container

vist dreiet 90° pm lengdeaksen i forhold til fig. 1. shown turned 90° around the longitudinal axis in relation to fig. 1.

Fig. 1 viser et spesielt utførelseseksempel på en beholder ifølge oppfinnelsen i tom tilstand. Folien 1 er langs en sammenhengende linje som forløper langs de ytre kanter 2, sveiset gasstett sammen med en geometrisk analog folie 1' (se Fig. 1 shows a particular design example of a container according to the invention in an empty state. The foil 1 is along a continuous line that runs along the outer edges 2, gas-tight welded together with a geometrically analogous foil 1' (see

fig. 2). De enkelte folier er således formet at de i sammén-sveiset tilstand som en helhet danner både lagringsrommet og en tilkoblingsdel 3. Sistnevnte sveises sammen langs linjen 12 etter at beholderen er fylt. Folien 1 er på et sted av sin overflate forsterket ved hjelp av en liten sirkulær plate 4 som består av et høyelastisk materiale, f.eks. silikongummi som er klebet gasstett fast til folien 1. På dette sted kan man ved hjelp av en injeksjonssprøyte ta ut små, nøyaktig doserte mengder av den lagrede gass. Når injeksjonssprøytens nål trekkes fig. 2). The individual foils are shaped in such a way that in the welded state they as a whole form both the storage space and a connecting part 3. The latter is welded together along the line 12 after the container has been filled. The foil 1 is reinforced in one place on its surface by means of a small circular plate 4 which consists of a highly elastic material, e.g. silicone rubber that is gas-tightly glued to the foil 1. At this point, small, precisely dosed amounts of the stored gas can be taken out with the help of an injection syringe. When the needle of the injection syringe is withdrawn

ut, vil beholderen automatisk bli lukket på innstikningsstedet som følge av elastisiteten av platen.4, således at der.ikke kan unnvike ytterligerei gass fra beholderen. out, the container will automatically be closed at the point of insertion as a result of the elasticity of the plate 4, so that no further gas can escape from the container.

For fylling av gassen henholdsvis for uttak av større mengder, anvendes tilkoblingsdelen 3 som for gassuttak skjæres over innenfor linjen 12 og åpningen derpå skyves inn på et rør som står i forbindelse med et apparat. Fullstendig tømming av beholderen oppnås ved at den rulles .eller trykkes sammen for hånd. Som følge av det lave overtrykk på mindre enn 1 atm. overtrykk er det unødvendig å foreta en mellomkobling av et kostbart . trykkréduksjonsapparat. For filling the gas or for withdrawing larger quantities, the connection part 3 is used, which for gas withdrawal is cut across within the line 12 and the opening is then pushed into a pipe which is connected to an apparatus. Complete emptying of the container is achieved by rolling it or pressing it together by hand. As a result of the low overpressure of less than 1 atm. overpressure, it is unnecessary to make an intermediate connection of an expensive . pressure reduction device.

Ved en diameter av beholderen på: 10 til 30 cm er beholderens 1 totale . flengde i normale tilfelle ikke mer enn 50 til 80 cm. Tilkoblingsdelens 3 diameter kan varieres alt etter behovet, men vil i alminnelighet ligge.mellom.1 og 2 cm. With a container diameter of: 10 to 30 cm, the container's 1 total . length in normal cases no more than 50 to 80 cm. The diameter of the connection part 3 can be varied according to need, but will generally be between 1 and 2 cm.

Når beholderen forsynes med et håndtak 5 som er fes-tet til beholdermantelen, kan den på fordelaktig måte henges påå på en vegg, f.eks. i et laboratorium. Fig. 2 viser et tverrsnitt-av en fylt beholder. Foliene består av en kombinasjon av plastskikt 6, 8, 10 og metallskikt 7, 9 som er fast forbundet med hverandre. Sådanne for gassfylling egnede, valgte kombinasjoner bevirker at beholderen blir helt gasstett og er samtidig ikke utsatt for korrosjon som følge av gassinnholdet. Samtidig har beholderen tilstrekkelig stabilitet for transport og en tilstrekkelig elastisitet og de-formerbarhet for tømming. Fig. 3 viser tilkoblingsdelen 3 ved en fylt beholder som en gang har vært åpnet og igjen lukket av forbrukeren. Tilkoblingsdelen er brettet 90° om sin lengdeakse. Gasstett-heten oppnås i dette tilfelle ved en enkel bretting eller opp-rulling av tilkoblingsdelens 3 fri ende i retning mot dens annen ende. Deretter kan lukkingen sikres ved hjelp av et eller annet hjelpemiddel, såsom et klebeband eller et kontorklammer e.l. When the container is provided with a handle 5 which is attached to the container jacket, it can advantageously be hung on a wall, e.g. in a laboratory. Fig. 2 shows a cross-section of a filled container. The foils consist of a combination of plastic layers 6, 8, 10 and metal layers 7, 9 which are firmly connected to each other. Such combinations, suitable for gas filling, ensure that the container becomes completely gas-tight and at the same time is not exposed to corrosion as a result of the gas content. At the same time, the container has sufficient stability for transport and sufficient elasticity and deformability for emptying. Fig. 3 shows the connection part 3 of a filled container which has been opened once and then closed again by the consumer. The connection part is folded 90° around its longitudinal axis. The gas density is achieved in this case by simply folding or rolling up the free end of the connecting part 3 in the direction towards its other end. The closure can then be secured using some aid, such as an adhesive tape or a paper clip etc.

Med en på denne måte konstruert lagringsbeholder som har lav vekt og dessuten er enkel og billig, kan behovet for With a storage container constructed in this way, which has a low weight and is also simple and cheap, the need for

små gassmengder eller gassblandinger i vitenskapelige labora-torier og skoler tilfredsstilles på enkel måte. Beholderen kan small amounts of gas or gas mixtures in scientific laboratories and schools are satisfied in a simple way. The container can

sendes pr. jernbane eller post, idet den er pakket i en ytre beholder, f.eks. i en hulsylindrisk papprull. sent per rail or post, as it is packed in an outer container, e.g. in a hollow cylindrical cardboard roll.

Beholderen ifølge oppfinnelsen er enkel og lett å bruke, således at også den ukyndige er i stand til å arbeide med den uten at der oppstår noen fare. The container according to the invention is simple and easy to use, so that even the unskilled person is able to work with it without any danger arising.
