Emballasjeeske. Packaging box.
Den foreliggende oppfinnelse vedrbrer en rettvinklet paral-lellepidedisk emballasjeeske dannet dels av et emne i ett stykke av kartong eller liknende, som ved hjelp av bbyningslinjer er inndelt i fire på rekke liggende, iallfall parvis like store felter for dannelse av eskens sider og med disse fire felter sammenhengende sidefliker for dannelse av endelukkingsdeler for esken, samt dels av et i hjbrnene uoppslisset fdr, som loper så langt The present invention relates to a right-angled parallelepipedic packaging box formed partly from a blank in one piece of cardboard or the like, which is divided by means of folding lines into four consecutive, at least in pairs, equal-sized fields to form the sides of the box and with these four fields continuous side flaps to form end closing parts for the box, as well as part of an unslitted front in the corners, which runs as far
utenfor eskens sider at det ved hjelp av en belgliknende bretting kan forsegles ved eskens ende, idet fdret for nevnte belgliknende outside the sides of the box, that it can be sealed at the end of the box by means of a bellows-like folding, as the spring for said bellows-like
bretting er fastklebet ved tre innbyrdes sammenhengende sidefliker av hvilke den mellomste av sideflikene har en lengde som er lik bredden av eskens to motstående sider mellom hvilke fliken er anbrakt, mens den fjerde flik som er atskilt fra de bvrige fliker og fra firet, er innrettet til i eskens forseglede tilstand å danne et lokk (en bunn) for samme. folding is glued to three interconnected side flaps, of which the middle of the side flaps has a length equal to the width of the two opposite sides of the box between which the flap is placed, while the fourth flap, which is separated from the other flaps and from the four, is aligned to in the sealed state of the box to form a lid (a bottom) for the same.
Fra svensk patent nr. 153.526 er det kjent en emballasjeeske av ovenfor beskrevne utfbrelse. Fårmaterialet er ved den kjente utfbrelse forlenget et såpass stykke utenfor kartongemnet at det under eskens sammenbrettlng blir ombrettet 180° om den ene av flikenes ytterkant og deretter ved klemvirkning blir fastlåst mellom denne flik og en overlappende, bunndannende eller lokkdan-nende flik. Fårmaterialet blir fblgelig avtettet ved klemvirkning mellom de to nevnte fliker. From Swedish patent no. 153,526, a packaging box of the above-described embodiment is known. In the known design, the sheep material is extended so far beyond the cardboard blank that, during the folding of the box, it is folded 180° around the outer edge of one of the flaps and is then clamped between this flap and an overlapping, bottom-forming or lid-forming flap. The sheep material is presumably sealed by a clamping action between the two mentioned tabs.
Ifblge oppfinnelsen tar man sikte på en helt annen forseg-lingsteknikk, hvor man oppnår en sikker forsegling og et redusert materialforbruk i forhold til det kjente forslag, idet man anven-der en varmeforsegling av fdrmaterialet istedenfor forsegling ved klemvirkning. According to the invention, the aim is a completely different sealing technique, where a secure seal is achieved and a reduced material consumption compared to the known proposal, by using a heat seal of the outer material instead of a seal by clamping action.
Emballasjeesken ifblge oppfinnelsen er kjennetegnet ved at f6ret lbper like langt utenfor esken som den mellomste flik, mens de to ytre av de tre innbyrdes sammenhengende fliker i hele sin bredde har en mindre lengde enn den mellomste flik. The packaging box according to the invention is characterized by the fact that the liner extends as far outside the box as the middle flap, while the two outermost of the three interconnected flaps have a shorter length than the middle flap throughout their width.
Av de to pressbakker som skal frembringe varmeforseglingen griper bare den ene pressbakke inn med firet, mens den andre griper inn med den mellomste flikens ytre kantparti, idet den nevnte flik ved hjelp av sin elastisitet opptar ujevnheter i trykkfordelingen mellom pressbakkene. Ujevnheter i trykkfordelingen mellom pressbakkene er praktisk talt umulig å unngå, da de opptrer som folge av slitasje i pressbakkemekanismen under dennes anvendelse. For at firmateriale skal komme til anlegg mot firmateriale er det viktig at de små fliker som er forbundet med den mellomste flik har en lengde som er mindre enn den mellomste flikens lengde. Of the two pressing trays which are to produce the heat seal, only one pressing tray engages with the four, while the other engages with the outer edge of the middle tab, as the said tab absorbs unevenness in the pressure distribution between the pressing trays by means of its elasticity. Unevenness in the pressure distribution between the press jaws is practically impossible to avoid, as they occur as a result of wear and tear in the press jaw mechanism during its use. In order for fir material to come into contact with fir material, it is important that the small tabs that are connected to the middle tab have a length that is less than the length of the middle tab.
Oppfinnelsen skal beskrives nærmere under henvisning til The invention shall be described in more detail with reference to
den medfølgende tegning, som viser en eksempelvis utfbrelsesform for emballasjeesken ifblge oppfinnelsen, hvor the accompanying drawing, which shows an exemplary embodiment of the packaging box according to the invention, where
Fig. 1 viser en del av eskeemnet utbrettet i planet. Fig. 1 shows part of the box blank unfolded in the plane.
Fig. 2 viser i perspektiv motsvarende del av emnet oppreist til en ennå ikke gjenlukket eske. Fig. 3 viser i perspektiv den oppreiste eske i forseglet tilstand.- Fig. 2 shows in perspective the corresponding part of the subject upright in a box that has not yet been resealed. Fig. 3 shows in perspective the upright box in a sealed state.-
Med henvisningstallet 1 betegnes eskeemnet som består av kartong eller liknende. Dette er ved hjelp av langsgående bbyningslinjer inndelt i fem felter 2-6. Feltene 2-5, som parvis er like store, er innrettet til å danne eskens sider, mens feltet 6 dannes av et klebefelt, som ved fremstillingen av esken er innrettet til å klebes fast til feltet 2. The reference number 1 denotes the box blank which consists of cardboard or similar. This is divided into five fields 2-6 by means of longitudinal building lines. The fields 2-5, which are of the same size in pairs, are designed to form the sides of the box, while the field 6 is formed by an adhesive field, which during the manufacture of the box is designed to be glued firmly to the field 2.
Sidefliker 7-10, som er innrettet til å danne eskens ende-lukking, henger sammen med feltene 2-5. Slike sidefliker 7-10 finnes fortrinnsvis på begge sider av feltene 2-5. Sideflikene 7-10 er avgrenset av feltene 2-5 ved hjelp av en bbyningslinje 11. Side flaps 7-10, which are arranged to form the end closure of the box, are connected to the panels 2-5. Such side tabs 7-10 are preferably found on both sides of fields 2-5. The side flaps 7-10 are delimited by the fields 2-5 with the help of a folding line 11.
Emnet 1 er utstyrt med et får 12,'som er beregnet å forsegles ved hjelp av varme og trykk eller bare ved hjelp av trykk og som helt dekker eskens innerside. Fåret 12 kan imidlertid også være anbrakt bare ved feltenes 2-5 ender. Fåret 12, som er uoppslisset i hjornene, loper så langt utenfor de sider av esken som danner feltene 2-5, at det ved hjelp av en belgliknende bretting kan forsegles ved eskens ender. Forut for nevnte belgliknende bretting er fåret 12 blitt fastklebet til de tre innbyrdes sammenhengende sidefliker 8, 9 og 10. Den fjerde sideflik 7, som er adskilt fra de bvrige fliker 8-10 og fåret 12, er innrettet til i eskens forseglete tilstand å danne et lokk henholdsvis en bunn for samme. The blank 1 is equipped with a flap 12, which is intended to be sealed by means of heat and pressure or only by means of pressure and which completely covers the inside of the box. However, the sheep 12 can also be placed only at the ends 2-5 of the fields. The fold 12, which is unslit in the corners, runs so far outside the sides of the box that form the fields 2-5, that it can be sealed at the ends of the box by means of a bellows-like folding. Prior to the aforementioned bellows-like folding, the flap 12 has been glued to the three interconnected side flaps 8, 9 and 10. The fourth side flap 7, which is separated from the other flaps 8-10 and the flap 12, is arranged to form in the box's sealed state a lid or a base for the same.
Ifblge oppfinnelsen har den mellomste flik 9 av de tre innbyrdes sammenhengende fliker. 8-10 en lengde, som iallfall stort sett er ]ik bredden for eskens to motstående sider 3 og 5 t mellom hvilke fliken 9 er plassert. Fåret loper dessuten like langt utenfor esken aom den mellomste flik 9> mens de to ytre fliker 8 og 10 av de tre innbyrdes sammenhengende fliker 8-10 har en mindre lengde enn den mellomste flik 9. According to the invention, the middle tab has 9 of the three interconnected tabs. 8-10 a length, which in any case is generally the width of the box's two opposite sides 3 and 5 t between which the tab 9 is placed. The sheep also runs as far outside the box as the middle flap 9>, while the two outer flaps 8 and 10 of the three interconnected flaps 8-10 have a shorter length than the middle flap 9.
Ifblge en utfbrelsesform er de to ytre fliker 8 og 10 hovedsakelig halvparten så lange som den mellomste flik 9 og utstyrt med brettingslinjer 13, som loper utad fra de indre hjbrner og fortrinnsvis er utstyrt med utstansninger, og som loper sammen med flikenes 8 og 10 ytre kant. Brettingslinjene 13 danner omtrent M-50 vinkel med bbyningslinjen 11,idet avvikelser fra h^° avhenger av materialets tykkelse. According to one embodiment, the two outer flaps 8 and 10 are mainly half as long as the middle flap 9 and equipped with folding lines 13, which run outwards from the inner corners and are preferably equipped with punches, and which run together with the outer sides of the flaps 8 and 10 edge. The folding lines 13 form an approximately M-50 angle with the folding line 11, as deviations from h^° depend on the thickness of the material.
Ved den viste utfbrelsesform er de to ytre fliker 8 og 10 ved den ytre kant utstyrt med en smal tunge 1<*>+, som loper fra midten og henad til flikenes 8 og 10 ene kant og som er avgrenset fra flikene 8 og 10 ved hjelp av en brettingslinje 15 som fortrinnsvis er utstyrt med utstansninger og som av hensyn til materialets tykkelse divergerer endel i forhold til bbyningslinjen 11. Tungene 1<*>+, som har sin'ene kant 16 anbrakt langs sidenes 3 og 5 midtlinje bidrar effektivt til å danne den belgliknende bretting av fåret 12. In the embodiment shown, the two outer flaps 8 and 10 at the outer edge are equipped with a narrow tongue 1<*>+, which runs from the center and upwards to one edge of the flaps 8 and 10 and which is delimited from the flaps 8 and 10 by by means of a folding line 15 which is preferably equipped with punches and which due to the thickness of the material diverges slightly in relation to the folding line 11. The tongues 1<*>+, which have sin'ene edge 16 placed along the center line of the sides 3 and 5 contribute effectively to to form the bellows-like folding of the sheep 12.
Den smale tunge 1M- loper fortrinnsvis henad til den av de The narrow tongue 1M preferably runs close to the one of them
to ytre flikers 8 og 10 kanter, som er vendt mot fliken 7, som the edges of two outer tabs 8 and 10, which face the tab 7, which
loper like langt fra eskens sider som tungene 11*. Fliken 7 har fortrinnsvis en lengde som er tre fjerdedeler av midtflikens 9 run as far from the sides of the box as the tongues 11*. The tab 7 preferably has a length that is three quarters of the middle tab's 9
lengde. length.
Det er vist eskeemnet i rbrformet tilstand i fig. 2 og The box blank is shown in a tubular state in fig. 2 and
f6ret 12 er nå fastklebet til de tre innbyrdes sammenhengende fliker 8,9,10, men derimot ikke til fliken 7. Avlukkingen av eskeenden innledes ved at sideflikenes 8,10 stbrste triangelfelt som fremkommer mellom brettelinjene 13, 11 ombbyes innad i rbr- The frame 12 is now glued to the three interconnected flaps 8,9,10, but not to the flap 7.

Sideflikenes 8, 10 minste triangelfelter blir herunder brettet 180° om linjene 13, slik at de danner anlegg mot det tilhbrende stbrste triangelfelt, mens tungene J\ h tilsvarende blir brettet 180° om linjen 15 i motsatt retning og slik at de anbringes på toppen av sideflikene 8, 10 og under midtfliken 9 som blir brettet 90° om linjen 11. Ved den tvangsmessige sammenbretting av flikene 8-10 brettes fåret 12 til- folded around the corresponding fold lines. The smallest triangular panels of the side flaps 8, 10 are then folded 180° around the lines 13, so that they form contact with the corresponding triangular panel, while the tongues J\h are accordingly folded 180° around the line 15 in the opposite direction and so that they are placed on top of the side flaps 8, 10 and below the middle flap 9, which is folded 90° around the line 11. When the flaps 8-10 are forcibly folded, the fold 12 is folded to
