  • a closure device that comprises interlocking fastening strips for closing the opening.
  • interlocking fastening strips are typically formed as elongated strips of semi-rigid, thermoplastic material and are provided as opposing pairs disposed along the opposite edges of the opening. Formed along the length of each strip are engagable closure profiles that are adapted to engage or mate with the corresponding profile formed on the opposing fastening strip. To allow for repeated access to the internal volume, the closure profiles are commonly configured to releasably and repeatedly engage each other.

  • the projecting female closure profile 132 includes first and second projections 162, 164 that are parallel to arid spaced-apart from each other a second distance.

[0026] On the male closure profile 130, sealant 136 is deposited into the three-sided gap or channel existing between the first and second projections 142, 144 and the base member 140.
  • Sealant 136 is likewise deposited on the female closure profile 132 into the gap created between the first projection 162 and the flange 174 and between the flange and the second projection 164.

Due to the semi-rigid characteristic of the fastening strip material, contact between the guide surfaces causes the male projections 142, 144 to flex inwardly and the female projections 162, 164 to flex outwardly. The barbs 146, 148 on the male projections 142, 144 and the barbs 166, 168 on the female projections 162, 164 can thereby slide past each other.
  • the resilient characteristic of the fastening strip material cause the male and female projections to flex back moving the barbs into an interlocking engagement with each other. Because of the semi-rigid and resilient characteristics of the fastening strip material, a sufficient, oppositely applied pulling force can disengage the male and female closure profiles.

  • the strips 422, 424 include profiled tracks 430 and 432 extending along the length thereof parallel to rib and groove elements 436 and 438.
  • the rib and groove elements 436, 438 have complementary cross-sectional shapes such that they are closed by pressing the bottom of the elements together first and then rolling the elements to a closed position toward the top thereof.
  • the rib element 436 is hook shaped and projects from the inner face of strip 422.
  • the complementary groove element 438 includes a lower hook shaped projection 440 and a relatively straight projection 442 which extend from the inner face of the second strip 424. Sealant 434 can be received and held in the groove element 438 as described above.

Abstract

L'invention concerne un élément de fermeture utilisé pour fermer une ouverture disposée le long de la paroi latérale souple d'un sachet de stockage, tel que ceux utilisés pour stocker des articles alimentaires. Les sachets de stockage de ce type fournissent un volume interne accessible via l'ouverture. Ledit élément de fermeture comprend une première bande de fixation et une seconde bande de fermeture par interverrouillage. Les première et seconde bandes de fixation comprennent un premier et un second profil de fermeture complémentaires pouvant coopérer. Pour fermer hermétiquement le volume interne, au moins une partie de la première ou de la seconde bande de fixation comprend un agent d'étanchéité. Cet agent peut être un fluide déplaçable, une substance du type fluide ou une substance du type cire, telle qu'une huile ou un gel. Lorsque les profils de fermeture coopèrent, l'agent d'étanchéité constitue une barrière d'étanchéité pour le volume interne.
