Description

Lukke for pakningsposer av kunststoff. Closure for plastic packing bags.

Oppfinnelsen vedrører et av kunststoff bestående lukke for pakningsposer med et strimmelformig lukkeorgan som danner en sløyfe som omslutter poseenden og hvis ender er løsbart forbundet med hverandre ved hjelp av et trykknappaktig forbindelsesmiddel. Oppfinnelsen består hovedsakelig i at lukkeorganet i den ene halvdel er forsynt med et ribbeformig fremspring og i den annen halvdel er forsynt med en overfor fremspringet beliggende sliss, i hvilken fremspringet ved lukking av lukket griper inn, idet poseenden gripes mellom slissen og ribben. The invention relates to a closure for packaging bags consisting of plastic with a strip-shaped closure member which forms a loop which encloses the bag end and whose ends are releasably connected to each other by means of a push button-like connection means. The invention mainly consists in that the closure member is provided in one half with a rib-shaped projection and in the other half is provided with a slot located opposite the projection, in which the projection engages when closing the closure, as the bag end is gripped between the slot and the rib.

Ved oppfinnelsen oppnås på en fordel-aktig måte et lukke for pakningsposer som er enkel i utførelse og billig i fremstilling, og som ikke vesentlig fordyrer den luft-tette pakning av vilkårlige gjenstander i fortrinnsvis gjennomsiktige kunststoff po-ser, samtidig som posen allikevel kan luk-kes pålitelig og luftett. The invention advantageously achieves a closure for packaging bags which is simple in design and cheap to manufacture, and which does not significantly increase the price of the airtight packaging of arbitrary items in preferably transparent plastic bags, while the bag can still be closed - is reliable and airtight.

To utførelsesformer for et lukke i henhold til oppfinnelsen er beskrevet i det føl-gende under henvisning til tegningen, hvor Two embodiments of a closure according to the invention are described in the following with reference to the drawing, where

Fig. 1 viser et lukke med klemsteg og trykk-knappforbindelse i snitt. Fig. 2 viser et perspektivriss av en ved hjelp av dette lukke lukket poseende. Fig. 3 viser nok en utførelsesform for et klemlukke i lengdesnitt. Fig. 4 viser et grunnriss til fig. 3. Fig. 5 viser en med lukke forsynt poseende i projeksjon på lukkestrimmelen. Fig. 6 viser anordningen i henhold til fig. 5 sett fra den annen side. Fig. 1 shows a closure with clamping step and push-button connection in section. Fig. 2 shows a perspective view of a closed bag end with the help of this. Fig. 3 shows yet another embodiment of a clamp closure in longitudinal section. Fig. 4 shows a ground plan of fig. 3. Fig. 5 shows a bag end fitted with a closure in projection onto the closure strip. Fig. 6 shows the device according to fig. 5 seen from the other side.

Det i fig. 1 og 2 viste poselukke består av et strimmelformig steg 19 som er halvert That in fig. The bag closure shown in 1 and 2 consists of a strip-shaped step 19 which is halved

ved et leddaktig utformet sted 20. Dette kan f. eks. bestå av et sted med liten tyk-kelse, mens den øvrige del av steget er for-holdsvis stivt. Eventuelt kunne de to steg-halvdeler også være forbundet med hverandre ved hjelp av et ledd. På den ene halvdel av steget 19 er der på en side anbrakt en ribbe 21 og i den annen halvdel er det anordnet en åpning 22, hvis indre vidde er noe større enn stegets 21 grunn-flate. På den ene ende av steget 19 er det anordnet en skive 23 med et ringspor. På den annen stegende er det anbrakt en ring 25, hvis indre vidde tilnærmelsesvis motsvarer den minste diameter av ringsporet 24 og som f. eks. på den overfor steget 19 liggende side kan være forsynt med en fremspringende tunge 26. Skiven 23, 24 danner sammen med ringen 25, 26 en trykknappaktig forbindelse og den sam-menbrettede ende av posen 3 blir som vist i fig. 15 lukket ved at de to halvdeler av steget 19 klappes sammen over poseenden, idet ribben 21 trenger inn i uttagningen 22 og poseenden i denne uttagning 22 hvelver seg ut mot en side. Ringen 25 skyves over skiven 23 og griper inn i ringsporet 24 så at de to halvdeler av steget 19 med den innklemte poseende holdes fast sammen ved hjelp av denne trykknappaktige forbindelse. at an articulated location 20. This can, e.g. consist of a place with little thickness, while the other part of the step is relatively rigid. Optionally, the two step halves could also be connected to each other by means of a link. On one half of the step 19, a rib 21 is placed on one side and an opening 22 is arranged in the other half, the inner width of which is somewhat larger than the base surface of the step 21. On one end of the step 19, a disc 23 with an annular groove is arranged. On the other rising end, a ring 25 is placed, the inner width of which approximately corresponds to the smallest diameter of the ring groove 24 and which, e.g. on the side opposite the step 19 can be provided with a protruding tongue 26. The disc 23, 24 forms together with the ring 25, 26 a push button-like connection and the folded end of the bag 3 becomes, as shown in fig. 15 closed by the two halves of the step 19 being folded together over the bag end, as the rib 21 penetrates into the recess 22 and the bag end in this recess 22 bulges out to one side. The ring 25 is pushed over the disk 23 and engages in the ring groove 24 so that the two halves of the step 19 with the pinched bag end are held firmly together by means of this push button-like connection.

Det i fig. 3—6 viste lukke består av en klemstrimmel 27 og en med denne i ett That in fig. The closure shown in 3-6 consists of a clamping strip 27 and one with this in one
