The present invention relates to a device for closing bags or the like, including two complementary profile members (A, B), characterized in that each of the two complementary profile members includes at least two profiled attachment elements (112, 114, 116, 118) for which form a multiple closure, in that said profiled elements for attachment have flattened portions (300) distributed over the length thereof, and in that said profiled attachment elements are supported by at least one respective support mat (102, 104) on which said profiled attachment elements are integrally formed, wherein the support mat is to be attached onto a support wall (500) and has a width (14) that is greater than the total width (13) of the profiled attachment elements.

A storage bag comprising first and second zipper profiles provided adjacent to an opening to the interior of the bag. The first and second zipper profiles are provided with opposing closure elements that respectively interlock with each other. The storage bag further includes first and second isolation sections between the first and second zipper profiles to prevent the opening of the first zipper profile from impacting the opening of the second zipper profile by a slider.

A fastening system includes two elongated profile parts, one of which includes a guiding surface or ramp for positioning it with respect to the other profile part, for releasably fastening a carrier to a holder. Deformations of a rib of one profile or a clamping hole of the other profile are adapted to position the one profile in substantially clamped state in the other profile in the longitudinal direction.

A hinged slider for a closure assembly of a bag includes a top wall and a pair of legs extending from the top wall. A first leg and a second leg of the pair each includes a top end attached to the top wall and a bottom end opposing the top end. A pair of wings is hingedly attached to the pair of legs. A first wing and a second wing of the pair is each hingedly attached to the bottom end of the first leg and second leg, respectively. The first wing and the second wing hinge upwardly in order (a) to engage the first wing to one of (i) the first leg and (ii) the second wing, (b) to engage the second wing to one of (i) the second leg and (ii) the first wing, and (c) to install the slider onto the closure assembly.

A surface bonding fastener for opening and closing an opening of a package comprises a first base sheet having a first surface; a second base sheet having a second surface facing the first surface; first and second blocking sheets secured to the first and second surfaces at first and second fixing ends; and plurality of first and second fastening units on first and second free ends opposite to the first and second fixing ends. The first and second fixing ends are closer to the opening of the package than the first and second free ends that are between the first and second base sheets. The first and second fastening units are arranged at intervals in a longitudinal direction and staggered in a transverse direction perpendicular to the longitudinal direction. The first and second fastening units are configured to be fastened with each other for closing the opening of the package.

A method for vacuum bag sealing a composite part including: using a composite bagging sheet including a first sealing surface and a first interlocking strip coupled to the first sealing surface of the composite bagging sheet; joining the first interlocking strip with a second interlocking strip coupled to a second sealing surface; and forming a sealed vacuum bag around an uncured composite part positioned between the first sealing surface and the second sealing surface.

The disclosure pertains to powder-resistant profiles for zippers or reclosures, such as may be used for reclosable packages. A first profile includes a first upper interlocking profile and a first lower interlocking profile, The second profile includes a second upper interlocking profile and a second lower interlocking profile. The first upper and lower interlocking profiles may include male elements while the second upper and lower interlocking profiles may include complementary female elements. A first central area is termed between the first upper and lower interlocking profiles and a second central area is formed between the second upper and lower interlocking profiles. The first and second central areas include respective first and second series of apertures through the male elements to allow powder otherwise trapped between the first and second profiles to escape or exit therethrough.

The present invention relates to a closure device for bags or the like comprising two complementary profiled elements (110, 210), characterized in that it involves sequential squeezing (300), of the two engaged profiled elements (110, 210), in a direction perpendicular to the support webs (100, 200).

The present invention relates to a device for closing pouches or the like comprising a series of complementary parallel profiles (110a-110e, 210a-210e), said profiles being carried by respective supporting sheets (100, 200), characterised in that said device has sequential alterations (300) in at least one profile (110, 210) along a direction perpendicular to the supporting sheets (100, 200).

A hinged slider for a closure assembly of a bag includes a top wall and a pair of legs extending from the top wall. A first leg and a second leg of the pair each includes a top end attached to the top wall and a bottom end opposing the top end. A pair of wings is hingedly attached to the pair of legs. A first wing and a second wing of the pair is each hingedly attached to the bottom end of the first leg and second leg, respectively. The first wing and the second wing hinge upwardly in order (a) to engage the first wing to one of (i) the first leg and (ii) the second wing, (b) to engage the second wing to one of (i) the second leg and (ii) the first wing, and (c) to install the slider onto the closure assembly.
