DK 169913 B1DK 169913 B1
Den foreliggende opfindelse angår en fremgangsmåde til fremstilling og pakning af levnedsmiddelprodukter og/-eller -præparater, hvilken fremgangsmåde især tager sigte på at kombinere en tillavet rets forskellige komponenter i en 5 enkelt pakning under sikring af lang holdbarhed ved omgivelsernes temperatur.The present invention relates to a process for the manufacture and packaging of food products and / or preparations, the method of which is particularly aimed at combining various components of a prepared dish into a single package, ensuring long shelf life at ambient temperature.
Opfindelsen angår også en pakning til sådanne levnedsmiddelprodukter og/eller -præparater, hvormed der sikres en lang holdbarhed.The invention also relates to a package for such food products and / or compositions, thereby ensuring a long shelf life.
10 For tiden er der i det væsentlige to måder at konser vere levnedsmiddelprodukter på: konserves i metaldåser og glasbeholdere har været kendt i en betragtelig tid. Disse pakninger påskønnes på grund af deres sikkerhedsmæssige aspekter og deres lange 15 holdbarhed (i en størrelsesorden på op til 3 år eller mere) uden særlige forholdsregler, og på grund af deres relativt lave pris. Produkternes organoleptiske egenskaber forringes imidlertid ofte ved sterilisationsbetingelserne. På den anden side er denne pakningsmetode meget påskønnet i hele 20 distributionsindustrien på grund af de logistiske faciliteter, den frembyder, da dåser eller beholdere kan placeres på hylder ved omgivelsernes temperatur uden nogen særlige forholdsregler.10 Presently, there are essentially two ways of preserving food products: canning in metal cans and glass containers has been known for a considerable time. These packages are appreciated because of their safety aspects and their long shelf life (up to 3 years or more) without special precautions, and because of their relatively low price. However, the organoleptic properties of the products are often impaired by the conditions of sterilization. On the other hand, this packing method is widely appreciated throughout the 20 distribution industry due to the logistical facilities it provides, since cans or containers can be placed on shelves at ambient temperature without any special precautions.
Dybfrosne produkter og retter har på den anden side 25 inden for de seneste år fået en stærkt øget betydning, hvilket gælder både konserveringen af levnedsmiddelprodukter i store portioner (grøntsager, kød osv.) og fremstillingen og pakningen af tillavede retter. Der er øget efterspørgsel efter denne sidstnævnte type produkt, da dybfrysning tillader 30 fremstillerne at anvende mange forskellige ,,madopskrifter,', hvilke nogle gange kunne være vanskelige og tidsforbrugende at anvende. En anden fordel ved denne metode er, at de forskellige komponenters organoleptiske egenskaber bibeholdes tilfredsstillende. På den anden side er begrænsninger med 35 hensyn til opbevaring og omkostninger i forbindelse hermed en signifikant faktor (frysere til store portioner, forbrugFrozen products and dishes, on the other hand, have gained a significant increase over the past few years, in terms of both the preservation of food products in large portions (vegetables, meat, etc.) and the manufacture and packaging of prepared dishes. There is an increased demand for this latter type of product, as deep freezing allows the 30 manufacturers to use many different "food recipes" which can sometimes be difficult and time consuming to use. Another advantage of this method is that the organoleptic properties of the various components are maintained satisfactorily. On the other hand, restrictions on storage and related costs are a significant factor (large portion freezers, consumption)

Endvidere kan de risici, der er forbundet med mulige fejl i frysekæden, ikke fuldstændig udeluk-5 kes.DK 169913 B1 2 of electrical energy), with the result that such products are expensive. The storage period is also shorter, on the order of one year only. Furthermore, the risks associated with possible errors in the freezing chain cannot be completely excluded.
Opfindelsen gør det muligt at kombinere fordelene ved begge de to metoder, der er omtalt ovenfor, samtidig med deres ulemper elimineres.The invention makes it possible to combine the advantages of both of the two methods discussed above while eliminating their disadvantages.
I FR patentskrift nr. 1.111.754 er der beskrevet en 10 stiv pakning, der indeslutter et antal bestanddele, der er pakket særskilt i fleksible indpakninger.FR Patent No. 1,111,754 discloses a rigid package which encloses a number of components packed separately in flexible packages.
Et af formålene med opfindelsen er at gøre fremstilling og pakning af levnedsmiddelprodukter og/eller -præparater mulig, hvorved komplette færdiglavede retter kan tilveje-15 bringes, og som har fremragende organoleptiske og gastronomiske egenskaber.One of the objects of the invention is to enable the preparation and packaging of food products and / or preparations, thereby providing complete ready-made dishes and having excellent organoleptic and gastronomic properties.
Med opfindelsen gøres også opbevaring af en sådan pakning ved omgivelsernes temperatur mulig.The invention also makes it possible to store such a package at ambient temperature.
Gennem opfindelsen tilvejebringes der en pakningsme-20 tode, hvor omkostningerne ved denne er sammenlignelige med omkostningerne ved dybfrosne produkter, og hvor opbevaringsomkostningerne er negligérbare.The invention provides a packaging method in which the cost thereof is comparable to the cost of frozen products and where the storage cost is negligible.
Med opfindelsen tilvejebringes der også en pakningsmetode, der giver en lang holdbarhedstid.The invention also provides a packing method which provides a long shelf life.
25 Opfindelsen angår således en fremgangsmåde til frem stilling og pakning af levnedsmiddelprodukter og/eller -præparater, ved hvilken forskellige levnedsmiddelprodukter og/eller -præparater pakkes i relativt impermeable fleksible indpakninger, og et antal fleksible indpakninger med 30 forskelligt indhold indesluttes i en stiv ydre pakning, og denne fremgangsmåde er ejendommelig ved, at man varmebehandler og/eller steriliserer, eventuelt under specifikke betingelser, i det mindste visse af næringsmiddelprodukterne i deres fleksible indpakninger, og at man genlukker den ydre 35 pakning indeholdende indpakningerne således, at den lukkes hermetisk og fri for praktisk taget ethvert spor af oxygen v, DK 169913 B1 3 i det indre deraf.The invention thus relates to a process for the manufacture and packaging of food products and / or preparations in which various food products and / or preparations are packaged in relatively impermeable flexible packages and a number of flexible packages of 30 different contents are enclosed in a rigid outer package. and this method is characterized by heat treating and / or sterilizing, optionally under specific conditions, at least some of the food products in their flexible packages, and closing the outer package containing the packages so that it can be hermetically and free. for practically any trace of oxygen v, in its interior.
Oxygen kan fjernes fra den ydre pakning ved at tilvejebringe et undertryk deri, når den lukkes, og/eller ved at indføre en neutral gas i denne pakning. Den ydre pakning 5 er foretrinsvis fremstillet i det væsentlige af metal.Oxygen can be removed from the outer gasket by providing a negative pressure therein when closed, and / or by introducing a neutral gas into this gasket. The outer gasket 5 is preferably made essentially of metal.
Opfindelsen angår også en pakning til levnedsmiddelprodukter og/eller -præparater, omfattende et antal relativt impermeable fleksible indpakninger indeholdende forskellige produkter samt en stiv ydre pakning, der indeslutter de 10 fleksible indpakninger, og denne pakning er ejendommelig ved, at i det mindste visse af de fleksible indpakninger indeholder levnedsmiddelprodukter, der er for-varmebehandlet og/eller steriliseret in situ, og at den ydre pakning er hermetisk lukket og fri for praktisk taget ethvert spor af 15 oxygen i det indre deraf.The invention also relates to a package for food products and / or compositions comprising a number of relatively impermeable flexible packages containing various products as well as a rigid outer package enclosing the 10 flexible packages, and this package is characterized in that at least some of the flexible packages contain food products that are pre-heat treated and / or sterilized in situ and that the outer package is hermetically sealed and free of practically any trace of oxygen in the interior thereof.
En af de vigtigste fordele ved den fremgangsmåde, der er defineret ovenfor, er det faktum, at de forskellige bestanddele nu kan steriliseres separat, og de kan derfor underkastes tids- og temperaturbetingelser, der er optimeret 20 for hvert levnedsmiddelprodukt eller -præparat. Dette gør det muligt at bibeholde alle levnedsmidlernes organoleptiske kvaliteter. Især undgås overopvarmning af visse levnedsmidler.One of the main advantages of the process defined above is the fact that the various components can now be sterilized separately and therefore subject to time and temperature conditions optimized for each food product or preparation. This enables the organoleptic qualities of all foods to be maintained. In particular, overheating of certain foods is avoided.
Det er nu også muligt på passende måde at sterilisere 25 visse "skrøbelige" levnedsmiddelprodukter, såsom fint kød og fisk, især fisk. Der er ikke længere nogen risiko for at disse produkter "desintegrerer" i løbet af sterilisationen, da pakningen i vakuum giver den ekstra kohæsion eller stivhed. Denne mekaniske støttende virkning, der hidrører fra 30 kombinationen af den fleksible indpakning og det anvendte vakuum, gør det muligt at bibeholde produktets originale udseende.It is now also possible to appropriately sterilize 25 certain "fragile" food products, such as fine meat and fish, especially fish. There is no longer any risk of these products "disintegrating" during sterilization, as the package in vacuum gives it extra cohesion or stiffness. This mechanical support effect resulting from the combination of the flexible package and the vacuum used makes it possible to maintain the original appearance of the product.
Da endvidere tilstedeværelsen af den ydre pakning benyttes til at eliminere risikoen for oxidation af produk-35 terne (dvs. hvis den ydre pakning i sig selv er evakueret eller fyldt med en neutral gas), kan de nævnte fleksible 4 DK 169913 B1 indpakninger fremstilles af et almindeligt billigt materiale, f.eks. en enkeltlaget film af almindeligt polypropylenplast-materiale. Den fleksible indpakning skal kun modstå varmebehandlings - sterilisationsbehandlingen (med andre ord, 5 den skal i det væsentlige kunne modstå en temperatur på ca.Furthermore, since the presence of the outer gasket is utilized to eliminate the risk of oxidation of the products (i.e. if the outer gasket itself is evacuated or filled with a neutral gas), the said flexible packages can be made of a common inexpensive material, e.g. a single-layer film of ordinary polypropylene plastic material. The flexible package should only withstand the heat treatment sterilization treatment (in other words, it should be able to withstand essentially a temperature of approx.
125eC), og have tilstrækkelig impermeabilitet således, at den kan beskytte levnedsmiddelprodukterne mod efterfølgende kontamination. Det faktum, at indpakningen er gennemsigtig, gør endvidere øjeblikkelig identifikation af de forskellige 10 komponenter mulig, uden at det er nødvendigt med nogen mærkning. Ikke desto mindre kan sammensatte filmmaterialer anvendes, især film, der indeholder flere lag materialer, herunder f.eks. et metallag (aluminium), der danner en supplerende oxygenbarriere.125 ° C) and have sufficient impermeability to protect food products from subsequent contamination. Furthermore, the fact that the packaging is transparent enables immediate identification of the various 10 components without the need for any labeling. Nevertheless, composite film materials may be used, especially films containing multiple layers of materials, including e.g. a metal layer (aluminum) forming an additional oxygen barrier.
15 Det skal til sidst bemærkes, at hvis den ydre pakning er af metal (der vil være den foretrukne løsning i størstedelen af tilfældene) , kan den have et enkelt design og udvise en mindre rafineret finish end former for metalpakninger, med hvilke levnedsmiddelprodukterne er i direkte kontakt. Den 20 indre lak er i almindelighed ikke længere nødvendig, og i nogle tilfælde kan tinbelægningen udelades. Som følge heraf reducerer kombinationen af fleksible indpakninger og den ydre pakning, enklere og mindre omkostningsfuldt, når det betragtes separat (enkeltlags indpakning af ordinært plastmate-25 riale på den ene side og metalpakning uden specielbehandling på den anden side) pakningsomkostningerne og gør slutproduktet konkurrencedygtigt ved sammenligning med et dybfrosset produkt. Som tidligere nævnt fås signifikante besparrelser på opbevaringsomkostningerne, da opbevaring ved omgivel-30 sernes temperatur og uden specielle forholdsregler er mulig, præcis som ved konventionelt konserverede-helkonservesproduk-ter.15 Finally, it should be noted that if the outer gasket is of metal (which will be the preferred solution in most cases), it may have a single design and exhibit a less refined finish than the forms of metal gaskets with which the food products are contained. direct contact. The 20 inner lacquers are generally no longer needed and in some cases the tin coating may be omitted. As a result, the combination of flexible packaging and the outer packaging, simpler and less costly when considered separately (single-layer packaging of ordinary plastic material on the one hand and metal packaging without special treatment on the other) reduces the packaging costs and makes the final product competitive at comparison with a frozen product. As mentioned earlier, significant savings are obtained on storage costs, since storage at ambient temperature and without special precautions is possible, just as with conventional canned whole preservatives.
Ud fra et sikkerhedshensyn opstår hovedproblemet ved dybfrosne produkter (risiko for tilfældig momentan optøning) 35 ikke. Endvidere kontaminerer en mulig nedbrydning af de produkter, der er indeholdt i én af de fleksible indpaknin- Λ Φ DK 169913 B1 5 ger, ikke nødvendigvis de andre.For safety reasons, the main problem with frozen products (risk of accidental thawing) 35 does not arise. Furthermore, a possible degradation of the products contained in one of the flexible packages does not necessarily contaminate the others.
Ved hjælp af eksempler vil de forskellige trin i fremgangsmåden ifølge den foreliggende opfindelse nu blive beskrevet. Det formodes med hensyn til dette eksempel, at 5 den ydre metalpakning til slut skal indeholde fleksible indpakninger, der hhv. indeholder kød, grøntsager og en sauce. Fremstillingen af grøntsagerne vil fortrinsvis omfatte de følgende operationer: - Grøntsagerne blancheres først, hvilket vil sige, at 10 de i få minutter nedsænkes i kogende vand.By way of example, the various steps of the process of the present invention will now be described. With regard to this example, it is believed that the outer metal gasket should eventually contain flexible packages which, respectively. contains meat, vegetables and a sauce. The preparation of the vegetables will preferably comprise the following operations: - The vegetables are first blanched, which means that they are immersed in boiling water for a few minutes.
- Portioner af grøntsagerne anbringes herefter i transparente fleksible polypropylenindpakninger i form af poser.- Portions of the vegetables are then placed in transparent flexible polypropylene wrappers in the form of bags.
- Poserne varmforsegles herefter under vakuum.- The bags are then heat sealed under vacuum.
15 - Poserne steriliseres herefter ved 120°C i ca. 15 minutter.15 - The bags are then sterilized at 120 ° C for approx. 15 minutes.
- Poserne afkøles herefter under kontrollerede betingelser.- The bags are then cooled under controlled conditions.
Det skal bemærkes, at opfindelsen bl.a. gør det muligt 20 at optimere sterilisations- og afkølingsoperationerne afhængigt af produktet i poserne.It should be noted that the invention includes enables 20 to optimize the sterilization and cooling operations depending on the product in the bags.
Parallelt med dette udføres lignende operationer, der underkastes forskellige opskrifter, der er egnede ved andre levnedsmiddelprodukter, hvorved tilvejebringes andre 25 poser, der indeholder henholdsvis vakuumpakket kød og sauce, eller mere generelt alle de nødvendige komponenter til en given færdiglavet ret.Parallel to this, similar operations are performed which are subjected to different recipes suitable for other food products, thereby providing other 25 bags containing vacuum-packed meat and sauce, or more generally all the necessary components for a given ready-made dish.
De forskellige poser transporteres herefter til en ydre pakningsstation, hvor metaldåseanordningerne fyldes 30 med et forudbestemt antal forskellige poser, hvorefter de lukkes hermetisk (f.eks. ved hjælp af konventionel krympning) under vakuum eller i en neutral atmosfære af nitrogen og/-eller carbondioxid.The various bags are then transported to an outer packing station where the metal box devices are filled with a predetermined number of different bags and then hermetically closed (e.g. by conventional shrinkage) under vacuum or in a neutral atmosphere of nitrogen and / or carbon dioxide. .
De forskellige operationsfaser, der netop er blevet 35 beskrevet, er kendt af fagfolk, hvilket er grunden til, at de ikke er blevet beskrevet yderligere i detaljer, og hvorfor DK 169913 B1 6 t J1' de automatiske installationer til udførelse heraf ikke er beskrevet. Det skal endvidere bemærkes, at vakuumpakning i plastposer gør disse indpakkede produkter egnede til sterilisation ved hjælp af mikrobølger. Den nødvendige temperatur 5 i levnedsmidlets centrum kan nås meget hurtigt ved hjælp af denne metode. Sterilisationstiden reduceres derfor til få minutter, uden at levnedsmidlernes yderside får en for kraftig varmebehandling.The various phases of operation just described are known to those skilled in the art, which is why they have not been described in further detail and why the automatic installations for carrying them out are not described. Furthermore, it should be noted that vacuum packaging in plastic bags makes these packaged products suitable for microwave sterilization. The required temperature 5 in the center of the food can be reached very quickly by this method. Therefore, the sterilization time is reduced to a few minutes without the outside of the food being subjected to excessive heat treatment.
Idet der henvises til tegningen beskrives nogle ek-10 sempler på pakninger til levnedsmiddelprodukter og/eller -præparater ifølge den foreliggende opfindelse. På tegningen viser fig. 1 en skematisk fremstilling af en pakning til levnedsmiddelprodukter og/eller -præparater, hvilke kan kom-15 bineres således, at der tilvejebringes en færdiglavet ret med en minimal tilberedningstid, fig. 2 viser en alternativ version af denne pakning, fig. 3 viser en detaljeret oversigt over en anden variant i stor skala, og 20 fig. 4 viser en detaljeret anskueliggørelse af en anden mulig variant.Referring to the drawing, some examples of food product packaging packages and / or compositions of the present invention are described. In the drawing, FIG. 1 is a schematic representation of a package for food products and / or preparations which can be combined to provide a ready-made dish with a minimum cooking time; FIG. Figure 2 shows an alternative version of this package; 3 shows a detailed overview of another variant on a large scale, and FIG. 4 shows a detailed illustration of another possible variant.
Pakningen i fig. 1 omfatter et antal fleksible indpakninger 12, 13, 14 i form af gennemsigtige poser af plastmateriale, og en enkelt hermetisk lukket stiv ydre pakning 25 16, der indeslutter disse fleksible indpakninger. Sidstnævnte er forseglet under vakuum, og er blevet steriliseret som beskrevet ovenfor. I dette eksempel kan en indpakning 12 f.eks. indeholde kød eller fisk, en indpakning 13 kan indeholde grøntsager, og en indpakning 14 kan indeholde en sauce, 30 hvor alle disse komponenter udvælges således, at de udgør en særlig færdiglavet ret. De fleksible indpakninger 12, 13 og 14 er relativt impermeable på den måde, at de mindst gør det muligt at opretholde levnedsmidlernes steriliserede tilstand og undgå rekontamination. På den anden side udgør 35 det anvendte plastmateriale (typisk polypropylenfilm) ikke nødvendigvis en absolut oxygenbarriere. Dette er grunden DK 169913 B1 7 til, at det mellemliggende rum 17 i den ydre pakning også sættes under undertryk eller fyldes med en neutral gas, når låget 19 krympes på.The gasket of FIG. 1 comprises a plurality of flexible packages 12, 13, 14 in the form of transparent plastic material bags, and a single hermetically sealed rigid outer package 25 16 enclosing these flexible packages. The latter is sealed under vacuum and has been sterilized as described above. In this example, a wrapper 12 can e.g. contain meat or fish, a wrapper 13 may contain vegetables, and a wrapper 14 may contain a sauce 30 wherein all of these components are selected so that they constitute a specially cooked dish. The flexible packages 12, 13 and 14 are relatively impermeable in that they at least make it possible to maintain the sterilized state of the foodstuffs and avoid recontamination. On the other hand, the plastic material used (typically polypropylene film) does not necessarily constitute an absolute oxygen barrier. This is the reason why the intermediate compartment 17 in the outer gasket is also pressurized or filled with a neutral gas when the lid 19 is shrunk.
I eksemplet i fig. 1 er den ydre pakning en metal-5 dåse af en type, der konventionelt anvendes i konservesindustrien, dvs. med en cylindrisk rørformet dåsekrop, en bund og et låg, hvor bunden og låget fastgøres ved hjælp af krympning, hvorved dåsen lukkes hermetisk. Som tidligere nævnt er det kun nødvendigt, at dåsen forsegles på gastæt 10 måde for at opretholde undertrykket eller den neutrale gasatmosfære. Det er ikke nødvendigt, at den ydre pakning er tinbelagt eller lakeret indvendig eller overtrukket på nogen måde.In the example of FIG. 1, the outer package is a metal can of a type conventionally used in the canning industry, ie. with a cylindrical tubular can body, a bottom and a lid, the bottom and lid being secured by shrinkage, thereby hermetically sealing the can. As mentioned earlier, it is only necessary that the can be sealed in a gas-tight manner in order to maintain the vacuum or the neutral gas atmosphere. It is not necessary that the outer gasket be tin-coated or lacquered inside or coated in any way.
I eksemplet vist i fig. 2 er udformningen anderledes 15 på den måde, at de fleksible indpakninger 12, 13 og 14 i dette tilfælde er anbragt i en "baljeformig" ydre pakning 16a, der er lukket ved hjælp af et låg 19a. Baljen 16a er stiv og er fremstillet af metal. Låget 19a kan også være et plademetallåg, der er falset til kanten af en åbning i 20 baljen. Det kan ligeledes som vist her være et relativt fleksibelt eller såkaldt "afskrælleligt" låg, der er fastgjort til en flad kant 21 på denne balje, hvilken løber rundt om åbningen på baljen, ved hjælp af varmforsegling eller en hvilken som helst anden kendt forseglet lukningsme-25 tode. Denne udførelse gør det muligt at åbne den ydre pakning uden at anvende nogen som helst form for værktøj. Det fleksible låg vil antage en svag konkav form på grund af vakuumpakningen, hvilken tilvejebringer en yderligere måde at kontrollere produktets tilstand på, når det købes.In the example shown in FIG. 2, the design is different 15 in that the flexible packages 12, 13 and 14 are in this case arranged in a "tubular" outer package 16a, which is closed by a lid 19a. The tub 16a is rigid and is made of metal. The lid 19a may also be a sheet metal lid folded to the edge of an opening in the tub. Also, as shown herein, it may be a relatively flexible or so-called "peelable" lid attached to a flat edge 21 of this tub, which runs around the opening of the tub, by means of heat sealing or any other known sealed closure means. -25 tode. This embodiment allows the outer gasket to be opened without the use of any tools. The flexible lid will assume a slightly concave shape due to the vacuum gasket, which provides a further way to check the condition of the product when purchased.
30 Den ydre pakning kan selvfølgelig lige såvel fyldes med en neutral gas for at beskytte levnedsmidlet mod langtidsoxidation.Of course, the outer gasket can also be filled with a neutral gas to protect the food from long-term oxidation.
I eksemplet i fig. 3 er baljen 16b i det væsentlige den samme som i fig. 2, men låget 19b er af stift metal, og 35 det er forsynet med en tætning 22, der hviler på den flade kant 21. I dette tilfælde holdes låget i det væsentlige ved DK 169913 Bl s hjælp af undertrykket i den ydre pakning, hvor dette låg holdes mod denne kant ved hjælp af dets tætningsmateriale.In the example of FIG. 3, the tub 16b is substantially the same as in FIG. 2, but the lid 19b is of rigid metal, and 35 is provided with a seal 22 which rests on the flat edge 21. In this case, the lid is held substantially by DK 169913 B1's aid of the negative pressure in the outer gasket, where this lid is held against this edge by its sealing material.
Dette tilvejebringer igen en passende måde at undersøge, om vakuet er blevet brudt under opbevaringen ved købstidspunk-5 tet. Pakningen kan let åbnes ved at gennembore låget. Der kan også tilvejebringes måder at ophæve vakuet på, f.eks. en selv-adhæsiv eller varmforseglet lap 22, der dækker over et hul 23 i den ydre pakning, hvor dette arrangement tilvejebringes f.eks. på selve låget.This, in turn, provides a convenient way of examining whether the vacuum has been broken during storage at the time of purchase. The gasket can easily be opened by piercing the lid. Ways may also be provided to cancel the vacuum, e.g. a self-adhesive or heat-sealed patch 22 covering a hole 23 in the outer package, where this arrangement is provided e.g. on the lid itself.
10 I eksemplet i fig. 4 er plademetal låget 19c bundet til en dåsekrop 16c ved enkel "pårulning" ved 25 på de kanter, der skal forbindes, hvorved man undgår fuldstændig falsning som i anordningen i fig. 1. I dette tifælde består låget (eller kanten af dåsekroppen) fordelagtigt af en ela-15 stomer materialepakning 26, der adhæsivt er bundet til låget nær dets kant.10 In the example of FIG. 4, the sheet metal lid 19c is bonded to a can body 16c by simple "rolling" at 25 on the edges to be joined, thereby avoiding complete folding as in the device of FIG. 1. In this case, the lid (or edge of the can body) advantageously consists of an elastomeric material gasket 26 which is adhesively bonded to the lid near its edge.
