Abstract
Oppfinnelsen vedrører en fremgangsmåte ved emballering av produkter (8), særlig næringsmidler, som legges i en kasseformet beholder (1) og dekkes med et tett, svøplignende banemateriale (9), særlig en plastfolie. Banematerialet (9) forbindes med beholderen (1) slik at det vil danne et lokk på beholderen. Oppfinnelsen vedrører også en kasseformet beholder (1) og en fremgangsmåte ved pakking og frysing av produkter.The invention relates to a method of packaging products (8), in particular foodstuffs, which are placed in a box-shaped container (1) and covered with a dense, wrapping-like web material (9), in particular a plastic film. The web material (9) is connected to the container (1) so that it will form a lid on the container. The invention also relates to a box-shaped container (1) and a method of packaging and freezing products.
Description
Oppfinnelsen vedrører emballasje av gjenstander og spesielt matvarer som skal underkastes en avkjølingsprosess. The invention relates to the packaging of objects and in particular foodstuffs which are to be subjected to a cooling process.
Pelagiske fiskevarer, for eksempel makrell og sild, fryses ned til - 30°C for transport. Varene anordnes i 20 kg kasser med trau og lokk, og svøp anordnes på Pelagic fish products, such as mackerel and herring, are frozen to -30°C for transport. The goods are arranged in 20 kg boxes with troughs and lids, and wraps are arranged on them
toppen av varene. Nedfrysing av varene foregår etter at de er plassert i kassene, og prosessen tar opptil 24 timer. Ved plassering i kassene dannes det et luftrom mellom produktet og lokket. Dette luftrommet er isolerende og fører til økt innfrysningstid. En av grunnene til at prosessen tar så lang tid er at kassen er isolerende og derfor må man trenge gjennom isolasjonen for å nå varene. the top of the goods. Freezing the goods takes place after they have been placed in the boxes, and the process takes up to 24 hours. When placed in the boxes, an air space is formed between the product and the lid. This air space is insulating and leads to increased freezing time. One of the reasons why the process takes so long is that the box is insulating and therefore you have to penetrate the insulation to reach the goods.
EP 1174354 viser en beholder med en bunn, sidevegger og innoverrettede kanter som rager frem fra sideveggene. Hensikten med kantene er å utgjøre en hvileflate for en plastfolie som kan sveises fast til disse for å lukke beholderen. Ulempen med en slik beholder er at ved å lukke den ved hjelp av plastfolien tilveiebringer man et luftmellomrom over den innpakkede varen. Beholderen vil dessuten ikke virke tilfredsstillende ved nedfrysing idet kompresjon av luften i luftmellomrommet vil føre til spenninger i foliematerialet og muligens til brudd av dette. EP 1174354 shows a container with a bottom, side walls and inwardly directed edges projecting from the side walls. The purpose of the edges is to form a resting surface for a plastic foil that can be welded to these to close the container. The disadvantage of such a container is that by closing it using the plastic film, an air gap is created above the wrapped item. The container will also not work satisfactorily when frozen, as compression of the air in the air gap will lead to stresses in the foil material and possibly to its breakage.
US 4,308,985 viser en beholder med fire vegger og en bunn, hvor veggene har utoverettede sideklaffer som danner en anleggsflate for en plastfolie for lukking av beholderen.» Sideklaffene vist i denne publikasjonen har en fast stilling og kan ikke brettes innover eller utover. Størrelsen på plastfoliens frie flate er fast etter at den festes til sideklaffene, og beholderen har således de samme ulempene som beholderen beskrevet i EP 1174354. US 4,308,985 shows a container with four walls and a bottom, where the walls have outwardly aligned side flaps which form a contact surface for a plastic foil for closing the container." The side flaps shown in this publication have a fixed position and cannot be folded inwards or outwards. The size of the free surface of the plastic foil is fixed after it is attached to the side flaps, and the container thus has the same disadvantages as the container described in EP 1174354.
En av hensiktene med oppfinnelsen er å forenkle innpakningsprosessen for varene. En annen hensikt er å redusere innfrysningstiden. One of the purposes of the invention is to simplify the packaging process for the goods. Another purpose is to reduce the freezing time.
Hensiktene oppnås ved hjelp av en fremgangmåte ved emballering av produkter, særlig næringsmidler, som legges i en kasseformet beholder og dekkes med et tett, svøplignende banemateriale, særlig en plastfolie som forbindes med beholderen slik at det vil danne et lokk på beholderen. The purposes are achieved by means of a method of packaging products, in particular foodstuffs, which are placed in a box-shaped container and covered with a dense, blanket-like web material, in particular a plastic film which is connected to the container so that it will form a lid on the container.
Fremgangsmåten ifølge oppfinnelsen er kjennetegnet ved at banematerialet legges på og over beholderåpningen og forbindes slik tett med utoverbrettede sideklaffer på beholderens sidevegger at når sideklaffene brettes innover mot beholderens midte, vil banematerialet slakkes mot produktene i beholderen. Fordelen med dette er at man tillater utvidelse av produktene i beholderen uten å danne et unødvendig luftrom. The method according to the invention is characterized by the web material being placed on and over the container opening and connected so tightly with outwardly folded side flaps on the side walls of the container that when the side flaps are folded inwards towards the center of the container, the web material will relax against the products in the container. The advantage of this is that it allows expansion of the products in the container without creating an unnecessary air space.
I en utførelse av oppfinnelsen bringes i det minste en del av den mellom beholderen og det til beholderen festede banemateriale forhåndenværende luft til å strømme ut fra beholderen. På denne måten sikrer man tilveiebringelse av et mellomrom mellom beholderens øvre flate (dvs. en flate som omfatter beholderens utover rettede sideklaffer) og banematerialet. I en utførelse av denne fremgangsmåte suges luften ut med et rør som stikkes gjennom en beholdervegg. In one embodiment of the invention, at least part of the air present between the container and the web material attached to the container is caused to flow out of the container. In this way, provision of a space between the container's upper surface (ie a surface that includes the container's outwardly directed side flaps) and the web material is ensured. In one embodiment of this method, the air is sucked out with a tube that is inserted through a container wall.
I en utførelse av fremgangsmåten er den kasseformede beholder plastlaminert og det baneformede materiale er en plastfolie som kan sveises til plastlaminatet. In one embodiment of the method, the box-shaped container is plastic laminated and the web-shaped material is a plastic foil that can be welded to the plastic laminate.
Oppfinnelsen omfatter også en kasseformet beholder for opptak av produkter, særlig næringsmidler, karakterisert ved at det på toppen av beholderens sidevegger er anordnet utover og innover ombrettbare sideklaffer, at sideklaffene på to motliggende beholdersider i begge ender er forlenget ut over den tilordnede sidevegglengde. The invention also includes a box-shaped container for receiving products, in particular foodstuffs, characterized in that foldable side flaps are arranged on top of the container's side walls outwards and inwards, that the side flaps on two opposite sides of the container at both ends are extended beyond the assigned side wall length.
I en utførelse er beholderen en fra et plant, plastlaminert emne, særlig en fiberplate, med plastlaminatet på innsiden oppreisbar beholder med hjørneinnbrett. In one embodiment, the container is a container with a corner insert that can be erected from a flat, plastic-laminated blank, in particular a fibreboard, with the plastic laminate on the inside.
Oppfinnelsen omfatter også en fremgangsmåte ved pakking og frysing av produkter, særlig næringsmidler, i en kasse, hvor kassen reises opp fra et plant, plastlaminert emne, kassen fylles med produkter i ønsket mengde, et svøp anordnes på toppen av produktene, kassen lukkes og underkastes en avkjølingsprosess, karakterisert ved at det som kasse benyttes en beholder hvor sideveggene på toppen er forsynt med ombrettbare sideklaffer, disse sideklaffer brettes utover og det som svøp legges en plastfolie på og over kassen, hvilken plastfolie også dekker de utbrettede sideklaffer, plastfolien sveises til sideklaffenes ytre kantområder og sideklaffene brettes innover mot kassens midte, og luft bringes til å strømme ut fra mellom kassens indre og plastfolien. The invention also includes a method for packing and freezing products, especially foodstuffs, in a box, where the box is raised from a flat, plastic-laminated blank, the box is filled with products in the desired amount, a wrap is arranged on top of the products, the box is closed and subjected to a cooling process, characterized by the fact that a container is used as a box where the side walls at the top are provided with foldable side flaps, these side flaps are folded outwards and a plastic foil is placed on and over the box as a wrap, which plastic foil also covers the unfolded side flaps, the plastic foil is welded to the side flaps the outer edge areas and the side flaps are folded inwards towards the center of the box, and air is forced to flow out from between the inside of the box and the plastic foil.
En grunnleggende idé ved oppfinnelsen er at svøp og lokk kombineres, idet svøpet festes slik til kassen at det vil lukke denne. Ifølge den kjente teknikken ligger svøpet under produktet og brettes over dette etter nedfrysningen. A basic idea of the invention is that the wrap and lid are combined, as the wrap is attached to the box in such a way that it closes it. According to the known technique, the wrap lies under the product and is folded over this after freezing.
De innoverbrettede sideklaffene vil stive av kassen tilstrekkelig for lagring og transport. Sveiseforbindelsen vil være beskyttet på undersiden av klaffene. The folded-in side flaps will stiffen the case sufficiently for storage and transport. The welding connection will be protected on the underside of the flaps.
Beholderen ifølge oppfinnelsen trenger således ikke et separert lokk for avstiving/trygt lagring av produktene. The container according to the invention thus does not need a separate lid for stiffening/safe storage of the products.
En fordel ved oppfinnelsen er at nedfrysningstiden reduseres til omtrent 16 timer. Emballasjens lokk omfatter hovedsakelig et plastsjikt, og dette sjiktet utgjør en mye lavere isolasjon enn lokkene ved den kjente teknikken. An advantage of the invention is that the freezing time is reduced to approximately 16 hours. The lid of the packaging mainly comprises a plastic layer, and this layer constitutes a much lower insulation than the lids of the known technique.
Vi vil nå beskrive oppfinnelsen nærmere ved hjelp av de vedlagte figurene 1-11, hvor: We will now describe the invention in more detail using the attached figures 1-11, where:

Figur 1 viser et flatt emne for fremstilling av beholderen. Figuren viser beholderen 1 før den reises opp. Beholderen omfatter sidevegger 2 og 4 med sideklaffer 3 hhv. 5, bunn 6 og hjørneinnbrett 7.1 denne utførelsen er sideveggene 2 kortere enn sideveggene 4. Figure 1 shows a flat blank for manufacturing the container. The figure shows the container 1 before it is raised. The container includes side walls 2 and 4 with side flaps 3 respectively. 5, bottom 6 and corner inset 7.1 in this version, the side walls 2 are shorter than the side walls 4.
Figur 2 viser oppretting av beholderens 1 sidevegger 2 og 4. Figure 2 shows the construction of the side walls 2 and 4 of the container 1.
Figur 3 viser beholderen 1 med oppreiste sidevegger 2 og 4 og sideklaffer 3 hhv. 5. Sideklaffene vil brettes ned senere i prosessen. Figur 4 viser beholderen 1 med utover brettede sidekanter 3 og 5.1 denne stilling danner sidekantene anlegg for banemateriale. Den oppreiste emballasjen 1 fylles med produkt 8 før påsveising av film 9. Figur 5 illustrerer anbringelse av et banemateriale 9 på beholderen. Banematerialet 9 er for eksempel PE/PET-film og emballasjen er for eksempel en fiberemballasje med PE/PET-laminat. Pilene A viser retningen for anbringelse av banematerialet 9. Figur 6 illustrerer forsegling av emballasjen ved hjelp av banematerialet 9. Sidekantene 3 og 5 er fortsatt brettet utover. Fiberemballasjen 1 er utformet med sideklaffer 3, 5 på både kortsidene 2 og langsidene 4. Disse sideklaffene 3, 5 kan brettes minimum 90 grader begge veier etter oppreising av trauet. Sidekantene har flere funksjoner. Etter oppreising av trauet, blir sideklaffene 3, 5 brettet 90 grader vendt utover fra emballasjens midtpunkt. Dette for at plastfilm 9 skal kunne sveises fast til sideklaffene 3, 5 gjennom bruk av varmeelementer. Forseglingen av film 9 mot fiberemballasje 1 med plastlaminat gjøres ved at plastlaminat og film 9 smelter sammen i kontaktpunktet ved den oppvarmede stålrammen i forseglingsmaskinen. Figur 7 illustrerer innover bretting av sidekantene 3 og 5. Etter påsveising av film, brettes sideklaffene 3, 5 180 grader innover mot emballasjens 1 midtpunkt. Dette medfører at arealet som plastfilmen skal dekke på innsiden av emballasjen reduseres. Effekten av dette medfører at headspace.mellom produkt 8 pakket i emballasjen 1 og sideklaffene 3, 5 plassert på toppen av emballasjen reduseres/elimineres som følge av at det oppstår et overskudd av plastmateriale og dermed kan plastfilmen 9 legges ned mot produktet 8 når produktets høyde er lavere enn emballasjens høyde. Figure 3 shows the container 1 with upright side walls 2 and 4 and side flaps 3 respectively. 5. The side flaps will be folded down later in the process. Figure 4 shows the container 1 with side edges 3 and 5 folded outwards. In this position, the side edges form a facility for track material. The upright packaging 1 is filled with product 8 before welding on film 9. Figure 5 illustrates placement of a web material 9 on the container. The web material 9 is, for example, PE/PET film and the packaging is, for example, a fiber packaging with PE/PET laminate. The arrows A show the direction for placing the web material 9. Figure 6 illustrates sealing of the packaging with the help of the web material 9. The side edges 3 and 5 are still folded outwards. The fiber packaging 1 is designed with side flaps 3, 5 on both the short sides 2 and the long sides 4. These side flaps 3, 5 can be folded at least 90 degrees both ways after erecting the trough. The side edges have several functions. After erecting the trough, the side flaps 3, 5 are folded 90 degrees and turned outwards from the center of the packaging. This is so that plastic film 9 can be welded to the side flaps 3, 5 through the use of heating elements. The sealing of film 9 against fiber packaging 1 with plastic laminate is done by the plastic laminate and film 9 fusing together at the contact point at the heated steel frame in the sealing machine. Figure 7 illustrates inward folding of the side edges 3 and 5. After welding on the film, the side flaps 3, 5 are folded 180 degrees inward towards the center of the packaging 1. This means that the area that the plastic film must cover on the inside of the packaging is reduced. The effect of this is that the headspace between the product 8 packed in the packaging 1 and the side flaps 3, 5 placed on top of the packaging is reduced/eliminated as a result of an excess of plastic material occurring and thus the plastic film 9 can be laid down against the product 8 when the product's height is lower than the height of the packaging.
Figur 8 illustrerer bretting av endende til sidekantene. Figure 8 illustrates folding of the ends to the side edges.
Figur 9 illustrerer utsuging av luft fra emballasjen. Utsugingen utføres for eksempel ved hjelp av en kanyle 9. Ved å trekke luft ut av emballasjen etter forsegling, oppstår en ytterligere reduksjon av headspace ved at man forsikrer seg at plastfilmen 9 trekkes ned mot produktets 8 overflate. Samtidig reduseres størrelsen av eventuelle luftlommer som har oppstått mellom produkt og plastfilm på produktets overflate som en direkte følge av at luft trekkes ut av emballasjen etter forsegling. Figure 9 illustrates extraction of air from the packaging. The extraction is carried out, for example, using a needle 9. By drawing air out of the packaging after sealing, a further reduction of headspace occurs by ensuring that the plastic film 9 is drawn down towards the product 8 surface. At the same time, the size of any air pockets that have arisen between the product and the plastic film on the product's surface is reduced as a direct result of air being extracted from the packaging after sealing.
Luft kan trekkes ut av emballasjen ved hjelp av en kanyle. Forsegling av emballasjen etter at kanylen er trekt ut av emballasjens side, gjøres ved at hullet tapes etter luftuttrekk og uttrekk av kanylen. Air can be extracted from the packaging using a needle. Sealing of the packaging after the needle has been pulled out of the side of the packaging is done by taping the hole after air extraction and withdrawal of the needle.
En alternativ metode for å redusere luftmengden i emballasjen etter forsegling, er å presse et stempel med et redusert areal i forhold til emballasjen indre areal (lengde x bredde) ned mot plastfilmen og produkt. Stemplet vil fysisk presse plastfilmen ned mot produktets overflate, for derigjennom å sørge for at headspace mellom produkt og plastfilm reduseres/elimineres. An alternative method to reduce the amount of air in the packaging after sealing is to press a stamp with a reduced area in relation to the packaging's internal area (length x width) down against the plastic film and product. The stamp will physically press the plastic film down against the product's surface, thereby ensuring that the headspace between the product and the plastic film is reduced/eliminated.
Emballasjen har selv etter forsegling mulighet for å slippe ut luft i hjørnene på emballasjens fire hjørner i området mellom sidekantene og sideklaffene. Figur 10 viser påføring av forsegling etter utsuging av luft. Tape 11 føres på åpningen etter kanylen 9 for å tette denne. Figur 11 viser beholderen 1 med banemateriale 9 etter vakuumering. Mellomrommet mellom banematerialets 9 overflatene og sidekantene 3 og 5 er gitt henvisningstall 12. Even after sealing, the packaging has the possibility of releasing air in the corners of the packaging's four corners in the area between the side edges and the side flaps. Figure 10 shows application of seal after extraction of air. Tape 11 is placed on the opening after the cannula 9 to seal it. Figure 11 shows the container 1 with web material 9 after vacuuming. The space between the surfaces of the track material 9 and the side edges 3 and 5 is given the reference number 12.
Fiberemballasjen 1 er konstruert slik at den er vanntett. Dette gjøres ved å benytte plastlaminat i fibermaterialet. Plastlaminatet er plassert ytterst i fibermaterialet, slik at plastlaminatet er kontaktmaterialet mot næringsmidlet. Fiberemballasjen har en vanntett konstruksjon ved at hele arket er uten utstansing i form av slisser. Bruk av riller for å brette opp hjørner og sidekantene medfører at piano emne kan reises opp til et trau, uten fare for vanngjennomtrenging gjennom emballasjekonstruksjonen. The fiber packaging 1 is constructed so that it is waterproof. This is done by using plastic laminate in the fiber material. The plastic laminate is placed at the outermost part of the fiber material, so that the plastic laminate is the contact material with the food. The fiber packaging has a waterproof construction in that the entire sheet is without punching out in the form of slits. The use of grooves to fold up the corners and the side edges means that the piano blank can be lifted up into a trough, without the risk of water penetration through the packaging construction.
Sideklaffene har en positiv effekt på emballasjens fysiske styrke, ved at sideklaffene når vendt 90 grader innover mot emballasjens midtpunkt, reduserer emballasjens mulighet for utbuling langs sidekantene. Sideklaffene vil etter å ha blitt vendt innover 90 grader, beskytte forseglingen mellom plastfilm og plastlaminat i fiberemballasjen mot uønsket avriving som en følge av at denne forseglingen blir liggende skjult under sideklaffene. The side flaps have a positive effect on the packaging's physical strength, in that the side flaps when turned 90 degrees inwards towards the center of the packaging, reduce the possibility of the packaging bulging along the side edges. The side flaps, after being turned inwards by 90 degrees, will protect the seal between plastic film and plastic laminate in the fiber packaging against unwanted tearing as a result of this seal being hidden under the side flaps.
