Title
(EN) BAG PUNCTURING MEANS
(FR) DISPOSITIF DE PERÇAGE D'UN SAC
Abstract
(EN)
A bag puncturing means including a cutter support (23) and a cutter (4) and a compression spring (1) both connected to the cutter support (23) in a manner such that rotation of the cutter support (23) will result in rotation of the cutter (4), and both located in the bore (25) of the cutter support (23) and extending beyond a first end of the cutter support (23). The cutter support (23) is adapted to be connected by screw threading to a nozzle (19) of a container liner (18) thereby to first engage a leading end (5) of the spring (1) with a membrane (20) covering the bore of the nozzle (19), then compress the spring (1), then force the cutter (4) against the membrane (20) to puncture and partially cut a flap (28) from the membrane (20) and thereby release the spring (1) which will expand into the interior of the liner (18) to prevent the flap (28) from entering the bore of the nozzle (19).
(FR)
Le dispositif de perçage d'un sac comprend un porte-lame (23) et une lame (4) ainsi qu'un ressort de compression (1), ces derniers étant reliés au porte-lame (23) de sorte que la rotation du porte-lame (23) se traduise par la rotation de la lame (4), tous deux étant situés dans l'espace cylindrique (25) du porte-lame (23) et s'étendant au-delà d'une première extrémité du porte-lame (23). Ce porte-lame (23) est adapté pour être relié par vissage à un ajutage (19) d'une garniture (18) d'un récipient pour, premièrement, mettre en contact une extrémité d'attaque (5) du ressort (1) avec une membrane (20) recouvrant l'alésage de l'ajutage (19) puis, deuxièmement, comprimer le ressort (1) pour pousser la lame (4) contre la membrane (20) afin de percer et couper partiellement un rabat (28) de la membrane (20); ensuite, le ressort (1) libéré se détend à l'intérieur de la garniture (18) pour empêcher le rabat (28) de pénétrer dans l'alésage de l'ajutage (19).
