Definitions
- the present invention relates to the field of closure for packaging, in particular resealable bags.
- the simplest profiles consist of a pair of profiles complementary: one male, the other female adapted to receive the profile aforementioned male.
- Document DE-2602323 is concerned with preventing the penetration of dust in a female profile. For this, it offers various solutions. First, it offers a link likely to break or a contact between two adjacent edges of concave structures defining the female profile (see figures 1 to 3, 8, 9). Then document DE-2602323 suggests adding flexible wings at the opening contour of the female profile, at the internal edge of the elements making up the profile female.
- the flexible wings in combination with the opening geometry defined in the elements composing the female profile, form a funnel for a product particulate so that the arrangement described in document DE-2602323 has limited efficacy.
- Document US-4020884 relates to a very different problem. In indeed, this document is concerned with prohibiting premature engagement of two closing profiles. For this, document US-4020884 proposes a bond liable to rupture between the internal edges of two elements forming closure profiles.
- the object of the present invention is to eliminate this drawback.
- a female type closure profile for resealable packaging characterized by the fact that it comprises on the top of the elements making up the profile female, flexible wings which prohibit or limit the penetration of particulate product in the female profile, while allowing the insertion of a complementary male profile in said female element, said wings flexible converge away from the support strip of said female profile and in direction of their free ends.
- These sections 10, 20 may have come from extrusion with a film forming the packaging, or even being integral with respective bands 11, 21 designed to be fixed by any appropriate means, for example by heat sealing, on such a film.
- the female profile 10 comprises two elements 12, 14 generally planar, mutually parallel and orthogonal to band 11, provided near their top and on their internal surface of respective projecting ribs 13, 15, converging in direction of the strip 11 and forming a concave opening contour for the female profile 10.
- This male profile 20 has a basic element 22 generally plane and orthogonal to band 21, which comprises at the level of its apex a symmetrical and tapered protuberance 23 adapted for penetrate the female element 10 and come into engagement with the ribs 13, 15.
- the profile female 10 is provided on the top of the elements 12, 14, with flexible wings 16, 18 which prohibit or limit the penetration of particulate product into the female profile 10, while allowing the insertion of the male profile complementary 20.
- These flexible wings 16, 18 are preferably come from extrusion with the female profile 10. However, as a variant, said flexible wings 16, 18 can be attached, for example heat-sealed, to the top elements 12, 14.
- the flexible wings 16, 18 are placed on the outside of the chamber internal of the female profile 10 opposite the opening contour thereof.
- the flexible wings 16, 18 are preferably symmetrical with respect to in the median plane of opening of the female profile 10. However, this condition is not always imperative.
- the flexible wings 16, 18 are tapered towards their end free.
- the flexible wings 16, 18 generally form in combination a convex dihedral particularly suitable for preventing the penetration of powder, by sliding of the pulverulent product on their external surface.
- the flexible wings 16, 18 at rest have an average inclination of the order of 20 ° relative to the support strip 10 and the interval between the free ends of the flexible wings 16, 18 is at most of the order of 0.2 mm.
- the invention is not limited to the geometry of the profiles illustrated in the appended figure.
- the invention can, for example, be applied to profiles comprising on the same strip, several complementary female profiles provided each of flexible wings 16, 18 or also to complementary profiles in manhole 10, 20, both formed of female type and each provided with wings flexible 16, 18.
