Description

Lukkeanordning for pose. Closing device for bag.

Nærværende oppfinnelse vedrører en lukkeanordning ved pose av termoplastisk materiale. Lukkeanordningen ifølge oppfinnelsen kommer til anvendelse for slike poser som er forsynt med en løpegang i hvilken er anbragt lukkesnorer, som ved å trekkes til, snurper sammen posens mun-ning, slik at denne lukkes. Slike poser har fått en utstrakt anvendelse for massear-tikler, som skal tas ut for bruk etter hvert, hvorved posen bør kunne lukkes mellom hver anvendelse. The present invention relates to a closure device for bags made of thermoplastic material. The closing device according to the invention is used for such bags which are provided with a running passage in which closing cords are placed, which, when pulled, close the mouth of the bag, so that it closes. Such bags have been widely used for bulk articles, which are to be taken out for use over time, whereby the bag should be able to be closed between each use.

Det er imidlertid en feil ved de tidligere kjente poser av denne type at de ikke kan lukkes hermetisk etter fylling og før de tas i bruk. Oppfinnelsen foreslår imidlertid en ombretning av slike posemunnin-ger som muliggjør at en praktisk løpe-gangsåpning ;kan bli bibeholdt, samtidig med at posen etter fylling kan lukkes hermetisk. However, there is a flaw in the previously known bags of this type that they cannot be closed hermetically after filling and before they are put into use. However, the invention proposes a re-alignment of such bag mouths which enables a practical running-through opening to be maintained, while at the same time that the bag can be hermetically closed after filling.

På tegningen er vist en pose ifølge oppfinnelsen, sett i plan i fig. 1. The drawing shows a bag according to the invention, seen in plan in fig. 1.

Fig. 2 viser rent skjematisk, hvorledes tidligere slike poser har vært anordnet, mens Fig. 2 shows purely schematically how previously such bags have been arranged, while

fig. 3 viser anordningen av en pose-munning ifølge oppfinnelsen, likeledes skjematisk. fig. 3 shows the arrangement of a bag mouth according to the invention, also schematically.

Posen ifølge eksemplet er fremstilt av en plastslange 1, som er lukket i den nedre ende, med en tversgående sveisesøm 10. I den øvre ende — munningsenden — er så posematerialet på kjent måte ombretttet slik at det dannes en løpegang. Ifølge oppfinnelsen er imidlertid som vist i fig. 1 og 3 ombretningen utført slik at materialet først brettes inn, forsynes med en sveise-søm 5, brettes så opp igjen ved 6, og ut gjennom munningsåpningen med et frem-springende parti 7. Dette parti 7 vil såle-des bestå av de mot hverandre liggende to flate partier av posen, og kan forsegles hermetisk ved en tversgående sveisesøm 8. The bag according to the example is made from a plastic tube 1, which is closed at the lower end, with a transverse welding seam 10. At the upper end — the mouth end — the bag material is then folded over in a known manner so that a runner is formed. According to the invention, however, as shown in fig. 1 and 3, the folding is carried out so that the material is first folded in, provided with a welding seam 5, then folded back up at 6, and out through the mouth opening with a projecting part 7. This part 7 will thus consist of the two flat parts of the bag lying next to each other, and can be hermetically sealed by a transverse welding seam 8.

Inne i løpegangene 2 kan trekksnorene 3 anbringes på vanlig måte og ved å trekke Inside the running passages 2, the pull cords 3 can be placed in the usual way and by pulling

i endene 4 vil posen snurpe seg sammen. Når en pose som den ifølge oppfinnelsen skal åpnes, rives først strimmelen 7 av etter svekningslinjen 9. Posen er derved åpen, men kan lukkes igjen ved hjelp av trekksnorene 3, 4. Denne sistnevnte luk-ning er imidlertid som det umiddelbart forståes ikke lenger hermetisk. at the ends 4 the bag will curl up. When a bag such as the one according to the invention is to be opened, the strip 7 is first torn off after the weakening line 9. The bag is thereby open, but can be closed again with the help of the drawstrings 3, 4. This latter closure, however, as is immediately understood, is no longer hermetically sealed .

I fig. 2 er som nevnt rent skjematisk antydet hvorledes slik poselukning har foregått tidligere. Posens 1' munningspar-tier 2' er ombrettet utover og er sammen-sveiset ved 5', slik at det fremkommer løpe-ganger for trekksnorene 3'. In fig. 2 is, as mentioned, purely schematically indicated how such bag closing has taken place in the past. The mouth parts 2' of the bag 1' are folded outwards and are welded together at 5', so that there are running passages for the pull cords 3'.
