Uppfinnare: S H Ericson Foreliggande uppfinning hdnfor sig till forslutningar for behallare samt till salt att framWalla dylika, sarskilt for vakuumtat forslutning av stora Oppningar i vaggarna till stone behallare, t. ex. stalfat. Med forbattringar i fraga om infodring eller belaggning av jarnfats insidor och i fraga wn behandling av de anmen eller material som skola inforas i dessa, ham det nu blivit mojligt att utnyttja behallare for forpackning av livsmedel, andra omtaliga varor, koncentrerade kemikalier osv. och fOrvara dem i &Ulna behallare under vakuum. Fat med dylika amnen, fyllda och forslutna under vakuum, kunna sedan bevaras i aratal utan att innehallet f8randras. Stora kvantiteter konserverade amnen kunna saledes hallas tillgangliga for anvandning vid behov. Inventor: S H Ericson The present invention relates to closures for containers as well as to salt to form such, especially for vacuum-sealed closures of large openings in the cradles of stone containers, e.g. stalfat. With improvements in the matter of lining or coating the insides of iron barrels and in the question of the treatment of the anmen or materials which are to be introduced into them, it has now become possible to use containers for packaging food, other notorious goods, concentrated chemicals, etc. and Store them in & Ulna containers under vacuum. Dishes with such substances, filled and sealed under vacuum, can then be preserved for years without changing the contents. Large quantities of preserved substances can thus be kept available for use when needed.

Det har emellertid uppstatt problem att anordna tillrackligt stora oppningar for att medgiva att fat, t. ex. sadana med en volym av upp till c :a 200 1, kunna fyllas snabbt och darefter effektivt f8rslutas pa sadant satt att vakuumet bibehalles efter fyllningen. Sadana problem lOsas genom fOrslutningen och forfarandet enligt uppfinningen. However, problems have arisen in arranging sufficiently large openings to allow barrels, e.g. such with a volume of up to about 200 l, can be filled quickly and then effectively sealed in such a way that the vacuum is maintained after filling. Such problems are solved by the closure and the method according to the invention.

Det ar foljaktligen ett andamal med uppfinningen att astadkomma forslutningar med avsevard storlek for forslutning av pa motsvarande salt dimensionerade oppningar i behallarens vaggar. Vidare avser uppfinningen att hstadkomma ldmpligt utformade Oppningar for dylika forslutningar, och att forsluta dylika oppningar for att sakerstalla att vakuum bibehalles i behallaren. Forslutningsanordningen enligt uppfinningen är av den typ som anges i ingressen till bifogade patentansprak 1. Kannetecknande for uppfinningen är att behallarva.ggens ringformiga vaggdelar omkring oppningen stracka sig i hub mig vinkel i forhallande till varandra och bilda en manna med uppatriktad fri kant i form av ett kort, sasom en stympad kon utformat parti, och att forslutningsorganet ãr utfort i form av ett forsankt lock med en kant, som är utformad som en neat oppen ringformig ranna med sidovaggar, som passa till behallarvaggdelarnas uppatriktade fria kant, och ha en fri andkant, vilken samverkar med behallarvaggrannans insida omkring Oppningen, samt att lockets kant liar en uppatriktad del, vilken samverkar med utsidan av behallarvaggens ranna mitt emot den fria kanten. Enligt en utforingsform astadkommes dylika fOrslutningar genom att de anbringas respektive genomforas fran behallarens utsida, sedan behallaren framstallts pa annat sail. De kunna ocksa anbringas respektive genomforas medan hela behallaren befinner sig under vakuum. Enligt ett annat utfarande kun_na forslutningarna vara tillräckligt stora for att i sig innefatta en ytterligare oppning samt forslutningsorgan for denna. Accordingly, it is an object of the invention to provide closures of considerable size for closing openings dimensioned on the corresponding salt in the walls of the container. Furthermore, the invention aims to provide simply designed openings for such closures, and to close such openings to ensure that vacuum is maintained in the container. The closure device according to the invention is of the type stated in the preamble of appended patent claim 1. A characteristic feature of the invention is that the annular cradle parts of the container wall extend around the opening at an angle in relation to each other and form a mandrel with an upwardly directed free edge in the form of a short, such as a truncated cone-shaped portion, and that the closure member is formed in the form of a recessed lid with an edge, which is designed as a neat open annular gutter with side cradles, which fit the raised free edge of the container cradle parts, and have a free breath edge, which cooperates with the inside of the container cradle neighbor around the opening, and that the edge of the lid has an upwardly directed part, which cooperates with the outside of the drain of the container cradle opposite the free edge. According to one embodiment, such closures are provided by being applied or made from the outside of the container, respectively, after the container has been manufactured on another sail. They can also be applied or passed through while the entire container is under vacuum. According to another method, the closures may be large enough to include in themselves an additional opening and closing means for this.

Ett lampligt satt att framstalla forslutningsanordningen enligt uppfinningen anges i bifogade patentansprak 3. An appropriate method of manufacturing the closure device according to the invention is stated in the appended patent claim 3.

En utfdringsform av fOrslutningsanordningen enligt uppfinningen skall nu beskrivas i exemplifierande syfte med hanyisning till bifogade ritning, ph vilken: fig. 1 am en planvy av oversidan eller gaveln av ett fat och visar forslutningsanordningen enligt uppfinningen anbragt pa denna gavel; fig. 2 är ett tvdrsnitt av fatoppningen med isarforda detaljer och visar forslutningsanordningen fardig att anbringas Over oppningen; fig. 3 am en sidovy, delvis i snitt och forstorad i forhallande till fig. 1, av forslutningsanordningen enligt uppfinningen anbragt ph sin plats Over Oppningen i en behallarvagg; fig. 4 dr ett vertikalsnitt Dupl. kl. 64 b: 22 2 av en behallarvagg med forslutningsanordningen anbragt i lage over oppningen i vaggen och visar forseglings- och infastningsmekanismen i lage for pfiverkan; samt fig. 5 fir en vy motsvarande fig. 4 och visar den fardiga fOrslutningen sedan f8rseglingen fullbordats. An embodiment of the closure device according to the invention will now be described by way of example with reference to the accompanying drawing, in which: Fig. 1 is a plan view of the top or end of a barrel and shows the closure device according to the invention mounted on this end; Fig. 2 is a cross-section of the barrel opening with ice-covered details and shows the closing device ready to be applied over the opening; Fig. 3 is a side view, partly in section and enlarged in relation to Fig. 1, of the closure device according to the invention arranged in its place Over the opening in a container cradle; Fig. 4 dr a vertical section Dupl. at 64 b: 22 2 of a container cradle with the closing device arranged in a layer over the opening in the cradle and showing the sealing and fastening mechanism in a layer for the pipe action; and Fig. 5 is a view corresponding to Fig. 4 showing the finished closure after the seal has been completed.

I fig. 1 visas oversidan eller ovre gaveln 1 av ett fat, forsedd med en 6ppning, som tillslutits med forslutningsoiganet 2 enligt upplinningen, vilket placeras mitt i fatgaveln. Just denna placering fir icke vasentlig, ty forslutningen kan placeras pa annat stalle pa gaveln eller oeksa pa flagon annan del av vaggen till behallare av samma eller avvikande typ. Vad som är viktigt är emellertid att forslutningsorganet och den av detta tillslutna oppningen har avsevard storlek i forhallande till storleken av behallarens gavel. Exempelvis kan en oppning med en diameter av 150 mm anvandas i en behallarsida eller -gavel med en diameter av c:a 600 mm. For speciella andamat kan forslutningsorganet 2 forses med en annan, mindre fOrslutning innanfor granserna till huvudforslutningens botten 3. Fig. 1 shows the upper side or upper end 1 of a barrel, provided with an opening, which is closed with the closing eye 2 according to the winding, which is placed in the middle of the barrel end. This particular placement is not essential, because the closure can be placed elsewhere on the gable or on the flake other part of the cradle to containers of the same or different type. What is important, however, is that the closing member and the opening closed by it have a considerable size in relation to the size of the end of the container. For example, an opening with a diameter of 150 mm can be used in a container side or end with a diameter of about 600 mm. For special purposes, the closure member 2 may be provided with another, smaller closure within the boundaries of the bottom 3 of the main closure.

Sasom framgar av fig. 2 är tillslutningsorganet 2 utfort som ett grunt, skalformat organ, vars botten 3 omgives av ett eylindriskt, uppsta.ende vaggparti 4, som fir ombockat eller falsat utat och neat yid 5 till ett vaggparti 6, vilket stracker sig parallellt med och ett styeke utanfor yaggpartiet 4, varvid en ranna 7 bildas mellan partierna. Vaggpartiet 6 fix yid sin underkant forsett med en utatriktad flans 8 for ett andamal, som framgar av det foljande. Tillslutningsorganet utfores normalt av jarnplat, som ãr nagot tunnare an den plat som anvandes for behallarvaggen men kan ocksa vara av lika tjockt material. As can be seen from Fig. 2, the closing member 2 is designed as a shallow, shell-shaped member, the bottom 3 of which is surrounded by a cylindrical, upright rocking portion 4, which is folded or folded outwards and neatly 5 to a rocking portion 6, which extends parallel with and a styeke outside the yagg portion 4, whereby a groove 7 is formed between the portions. The cradle portion 6 fix yid its lower edge provided with an outwardly directed flange 8 for a second dimension, which is apparent from the following. The closing member is normally made of iron plate, which is slightly thinner than the plate used for the container cradle but can also be of the same thickness of material.

Rannans 7 botten fix under vulsten 5 utfylld av en packning 9, som foretradesvis utformats genom att en flytande mama hallts pa plats i rannan, varpa massan fatt stelna eller hardna. Harigenom sakerstalles att packningen kommer att befinna sig i fullstandigt ingrepp med rannans botten Over hela sitt tvarsnitt, och packningen bibringas en riktig form f6r det avsedda andamalet. The bottom of the gutter 7 is fixed under the bead 5 filled with a gasket 9, which is preferably formed by holding a liquid mama in place in the gutter, warping the mass to solidify or harden. This ensures that the gasket will be in complete engagement with the bottom of the gutter over its entire cross-section, and the gasket is given a proper shape for the intended purpose.

Fatgayeln 1 ãr forsedd med lamplig utbildning for effektiv samverkan med forslutningsorganet, sa att detta latt kan anbringas pa sin plats med mekaniska medel i en tat vakuumkammare och darefter samverkar med forslutningsorganet pa sadant salt att ett vakuumtatt forband med lang varaktighet astadkommes. Den del av behallarvaggen som stracker sig kring oppningen innefattar salunda ett forsta nedatriktat och Mat lutande, ringformigt parti 10, som straeker sig fram till ett bojningsstalle 11, varifran ett andra, ringformigt lutande parti 12 stracker sig uppat och Mat. Fran dettas inre ande är en cylindrisk krage eller stuts 13 dragen uppat for att inrama oppningen 14. The barrel 1 is provided with suitable training for effective co-operation with the sealing member, so that it can be easily applied in place by mechanical means in a tight vacuum chamber and then co-operates with the sealing member on such salt that a vacuum-tight bandage of long duration is achieved. The part of the container cradle which extends around the opening thus comprises a first downwardly directed and Mat inclined, annular portion 10, which extends to a bending stall 11, from which a second, annular inclined portion 12 extends upwards and Mat. From its inner spirit a cylindrical collar or stub 13 is pulled upwards to frame the opening 14.

Air fig. 4 framgar att tillslutningsorganet 2 forst lagges ned kring oppningen 14 med vaggpartierna 4 och 6 och vulstpartiet 5 i sjalva verket bildande en ranna, med vars hjalp forslutningsorganet hanges I oppningen. Den senare tillslutes av botten 3, och vaggpartierna 4 och 6 med det mellanliggande kragpartiet 13 passas samman i koncentriskt lage. Nar palorandet eller ansattningen fortskridit i onskad utstrackning, sh att packningen 9 komprimeras pa raft satt och bringas att flyta kring kragens 13 ovre aride 15 och en salter tatning bildats, hejdas fortsatt kompression genom att flansen 8 ingriper med det lutande partiets 12 utsida, varigenom packningen skyddas mot allt fOr kraftig kompression och forstoring. Air Fig. 4 shows that the closing member 2 is first laid down around the opening 14 with the cradle portions 4 and 6 and the bead portion 5 in fact forming a gutter, with the aid of which the closing member is hung in the opening. The latter is closed by the bottom 3, and the cradle portions 4 and 6 with the intermediate collar portion 13 are fitted together in a concentric position. When the coloring or application has progressed to the desired extent, so that the gasket 9 is compressed and made to float around the upper arid 15 of the collar 13 and a salt seal is formed, continued compression is stopped by the flange 8 engaging the outside of the inclined portion 12, whereby the gasket protected against everything from excessive compression and magnification.

I verkligheten, under driftsfOrhallanden i vakuumkammaren, Hiles tillslutningsorganet 2 i lage ovanfor fatets gavel, tills fatet fyllts, och fores sedan till sateslage i oppningen 14 med hjalp av en mekanism som stukar forslutningen pa plats. Fasthallningen sker med hjalp av ett magnetelement 16, som ãr anbragt i en urtagning, vilken stacker sig upp i stukningsverktygets manoverspindel 17. Detta stukningsverktyg, av vilket endast vasentliga sardrag beskrivas har, Or forsett med ett flertal sasom segment utbildade expansions-backer 19, vilka uppbaras av utat glidbara organ 20, som rora sig 1 en urtagning 22 i ett mothallsorgan 23. Nar baekarna 19 intaga sitt aterforda eller indragna lage bilda deras sammansatta mantelytor en hel cirkel. Backarna 19 ha radiellt utatriktade, avrundade utsprangspartier 21 utformade att ingripa med nedre delen av forslutningsorganets sidovagg 4 vid en sadan punkt att denna del pressas utat mot undersidan av det parti 12 som ()Inger behallarvaggens krage. Ovanfor sina utskjutande partier 21 aro backarna 19 urtagna radiellt Mat, sa att ett lutande parti 24 bildas. Oversta delen av detta parti 24 in-griper natt och jamt med oversta delen av vaggen 4, innanfor vulsten 5, nfir verktyget befinner sig i sitt vilolage, sasom framgar av fig. 4. Harigenom Mlles organet 2 centrerat och fardigt att anbringas Over oppningen. Nar forslutningsorganet 2 val satts pa sin plats i oppningen, drages spindeln 17 uppat med sin koniska utsida 25 glidande mot de koniska ytpartierna 26 av backorganen 19 och dessas barelement 20. Harigenom expandera backorganen 19 radiellt utat for att fasta f8r slutningsorganet pa sin plats. 3 Det massiva mothallet 23 ãr f6rsett med en ringformigt arbetsyta 27, som omger det med 8ppningsbildningen hopsatta f5rslutningsorganet. Mothallet ligger nara intill vaggpartiet 6, sa att dessas ytor 24 i och med att backarna 19 expandera utat bocka ovre delen av forslutningsorganets vaggpartier 4 och 6 med den mellan dessa imieslutna kragen 13 utat till det i fig. 3 och 5 visade laget. Pa samma gang pressa utsprangen 21 nedre delen av vaggen 4 utat under det oppningen bildande partiet 12 onupp mat detta, sasom synes vid 28. Forslutningsorganet bringas salunda till tatt ingrepp med godset i behallarvaggen pa bade insidan och utsidan am detta gods, med flansen 8 och partiet 28 ingripanda mot partiets 12 motsatta sidor. Packningen 9 Mlles i ett intimt tatande lage, sâ att en effektiv och varaktig vakuumforslutning sakerstalles. In fact, during operating conditions in the vacuum chamber, the closure member 2 hiles in a position above the end of the drum, until the drum is filled, and is then moved to a set position in the opening 14 by means of a mechanism which locks the closure in place. The clamping is effected by means of a magnetic element 16, which is arranged in a recess, which protrudes into the operating spindle 17 of the upsetting tool. This upsetting tool, of which only essential features are described, is provided with a plurality of expansion jaws 19 formed as segments, which supported by outwardly slidable members 20, which move in a recess 22 in an abutment member 23. When the cups 19 assume their recessed or retracted layer, their composite circumferential surfaces form a full circle. The jaws 19 have radially outwardly directed, rounded projections 21 designed to engage with the lower part of the side cradle 4 of the closing member at such a point that this part is pressed outwards towards the underside of the portion 12 which () inserts the collar of the container cradle. Above its projecting portions 21, the jaws 19 are recessed radially Mat, so that an inclined portion 24 is formed. The upper part of this portion 24 engages at night and jamt with the upper part of the cradle 4, inside the bead 5, when the tool is in its resting position, as shown in Fig. 4. Hereby the Mlles member 2 is centered and ready to be placed over the opening. When the closure member 2 is selectively placed in place in the opening, the spindle 17 is pulled upwards with its conical outside 25 sliding against the conical surface portions 26 of the jaw members 19 and their bar members 20. Thereby the jaw members 19 expand radially outwardly to secure the closure member in place. The solid abutment 23 is provided with an annular working surface 27, which surrounds the closing member assembled with the opening formation. The abutment lies close to the cradle portion 6, so that their surfaces 24 as the jaws 19 expand outwardly bend the upper part of the cradle portions 4 and 6 of the closure member with the collar 13 between them closed outwardly to the layer shown in Figs. 3 and 5. At the same time, the projections 21 press the lower part of the cradle 4 outwards under the opening-forming portion 12 to open it, as can be seen at 28. The closing means is thus brought into engagement with the goods in the container cradle on both the inside and outside of this goods, with the flange 8 and the party 28 intervenes against the opposite sides of the party 12. The gasket 9 is milled in an intimate sealing layer, so that an efficient and lasting vacuum seal is ensured.

Ehuru en f. n. foredragen utforingsform av uppfinningen visats och beskrivits ovan, ãr det givetvis underforstatt att detta endast skett i illustrativt och icke begransande syfte. Although a presently preferred embodiment of the invention has been shown and described above, it is to be understood that this has been done for illustrative and non-limiting purposes only.
