An airtight closure mechanism for a reclosable pouch includes first and second complementary closure elements, the first closure element comprising a first interlocking profile and the second closure element comprising a complementary second interlocking profile. First and second sealing sections are disposed on respective complementary sides of the first and second interlocking profiles. The first sealing section includes a first protuberance having a first distal surface, a second protuberance having a second distal surface, and a sealing flange attached to and extending between the first and second distal surfaces of the first and second protuberances, respectively. The second sealing section includes a sealing member disposed on a base of the second closure element. The sealing member is located a distance from the second interlocking profile that places a distal surface thereof between the first and second protuberances when the first and second interlocking profiles are occluded. Additionally, when the first and second interlocking profiles are occluded, the distal surface urges against the sealing flange to form an airtight seal therebetween.

Mécanisme de fermeture étanche pour sac refermable comprenant un premier et un second éléments de fermeture complémentaires, le premier élément comportant un premier élément profilé imbriqué et le second élément de fermeture comportant un second élément profilé imbriqué complémentaire. La première et la seconde sections d'étanchéité sons disposées sur les côtés complémentaires respectifs des deux premiers éléments profilés imbriqués. La première section d'étanchéité comprend une première protubérance comportant une première surface distale, une seconde protubérance comportant également une seconde surface distale, ainsi qu'une bride de fermeture fixée entre les deux surfaces distales des deux protubérances et se prolongeant entre les deux surfaces respectives susmentionnées. La deuxième section d'étanchéité comprend un élément d'étanchéité disposé sur une base du second élément de fermeture. L'élément d'étanchéité se trouve à une distance du second élément profilé imbriqué, ce qui place la distance distale dudit élément entre les deux premières protubérances lorsque les deux premiers éléments profilés imbriqués sont raccordés. De plus, lorsque les deux premiers éléments profilés imbriqués sont raccordés, la surface distale entre en contact avec la bride de fermeture, ce qui forme un sceau étanche à l'air entre ces deux éléments.
