Description

Varmforseglbar beholder.Heat sealable container.

Oppfinnelsens gjenstand er en varmforseglbar beholder, hvis forseglingssøm har en lukket kontur med utbuktning. The object of the invention is a heat-sealable container, the sealing seam of which has a closed contour with a bulge.

Ved de kjente ved hjelp av forseglingssøm lukkede beholdere av forseglbart kunststoff eller av et med forseglbart kunststoff kasjert metall er sømmens kontur utformet fullstendig kontinuerlig, dvs.- den er sirkelformet ved sylindriske beholdere og firkantet med avrundede hjørner ved kvadratisk eller firkantet beholder. Størrelsen av den kraft som er nødvendig til oppriv-ning av en forseglingssøm er proporsjonal med sømstrekningen, hvor kraften må angripe. Denne sømstrekning er ved de kjente sømkonstruksjoner ved frøste riving - riving betyr å opprive sømmen såvidt at det er dannet en forbindelse mellom beholderens ytre og indre rom - spesiell stor og blir stadig større medøkende radius av konturen. Kraften til riving av sømmen kan derfor utgjøre mange ganger det som ennå er nødvendig til ppp-riving av den revede søm. In the case of the known containers made of sealable plastic or of a metal lined with sealable plastic closed by means of a sealing seam, the contour of the seam is designed completely continuously, i.e. it is circular in the case of cylindrical containers and square with rounded corners in the case of square or rectangular containers. The magnitude of the force required to tear a sealing seam is proportional to the seam length, where the force must attack. In the case of the known seam constructions, this seam stretch is at first tearing - tearing means tearing up the seam to the extent that a connection has been formed between the outer and inner space of the container - particularly large and becomes increasingly larger with the increasing radius of the contour. The force for tearing the seam can therefore amount to many times what is still necessary for ppp tearing of the torn seam.

Det besto følgelig den oppgave å tilveiebringe en varmforseglbar beholder, hvor kraften til riving av forseglings-sømmen størrelsesmessig ikke er større enn den kraft som må an-bringes til oppriving av sømmen etter foretatt riving. The task was therefore to provide a heat-sealable container, where the force for tearing the sealing seam is not greater in terms of size than the force that must be applied to tear the seam after tearing.

Oppgaven løses ved en varmforseglbar beholder, hvis forseglingssøm har en lukket kontur, og hvis lokk en rivlask, idet beholderen erkarakterisert vedat forseglingssømmen på et sted har en utbulning som dannes av to rette sømavsnitt, idet de to sømavsnitt danner en vinkel på 6 0° til 12 0°. The task is solved by a heat-sealable container, whose sealing seam has a closed contour, and whose lid has a tear flap, the container being characterized in that the sealing seam in one place has a bulge formed by two straight seam sections, the two seam sections forming an angle of 60° to 12 0°.

Spesielt fordelaktig er en vinkel på 90°, hvis topp viser i retning mot rivlasken. Particularly advantageous is an angle of 90°, the top of which points in the direction of the grater.

Ved utbuktning ifølge oppfinnelsen av forseglings-. sømmen .innledes kreftene til riving av sømmen over toppen av utbulningen i sømmen og oppnår i det videre forløp av åpningen bare størrelsesorden av de krefter som er nødvendig til oppriving av den fullstendig revne søm. When bulging according to the invention of sealing-. the seam .the forces for tearing the seam begin over the top of the bulge in the seam and in the further course of the opening only achieve the order of magnitude of the forces necessary to tear the completely torn seam.

Oppfinnelsen skal forklares nærmere i det følgende under henvisning til tegningen, hvor The invention will be explained in more detail below with reference to the drawing, where

fig. 1 viser et oppriss av beholderen,fig. 1 shows an elevation of the container,

fig. 2 viser, et sideoppriss av beholderen med delvis opprevet lokk. fig. 2 shows a side elevation of the container with a partially torn lid.

Beholderen 1 med utkragende kant 2 er forseglet med et lokk 3 som har en riylask 4. Beholder og lokk består enten av varmforseglbart materiale eller er kasjert med et slikt når beholder og/eller lokk består av metall. Forseglingssømmen 5er utstyrt med en utbulning som dannes av de rette sømavsnitt 6 og 6a. Toppen 7 av utbulningen viser i retning av rivlasken 4. The container 1 with cantilevered edge 2 is sealed with a lid 3 which has a zipper 4. The container and lid either consist of heat-sealable material or are lined with such when the container and/or lid consist of metal. The sealing seam 5 is equipped with a bulge formed by the straight seam sections 6 and 6a. The top 7 of the bulge points in the direction of the riving blade 4.
