  • Patent number: 11305917
    Abstract: A bag including a childproof resealable closure system. The bag includes an opening extending from a first end to a second end configured with a closure system to seal the opening. The closure system includes a first elongate closure element and a second elongate closure element, coupled to opposing sidewalls of the bag and extending from the first end to the second end. The first and second elongate closure elements may be resealably interlocked to provide the seal. The first closure element may be coupled to its sidewall along its lower portion while leaving the upper portion of the closure element substantially disconnected. The second closure element may be coupled to its sidewall along its upper and lower portions. The second closure element may include a discreet partial gap along its length to facilitate the gripping and separating of the closure system, to render the resealable bag childproof.

  • Patent number: 11083251
    Abstract: A closure device for detachably connecting two parts to one another includes a first closure part which has at least two first magnetic sections which are spaced apart from one another and form an intermediate space between one another, and a second closure part which has at least one second magnetic section. The first closure part and the second closure part can be attached to one another along a closure direction in such a way that the closure device assumes a closed position in which the at least one second magnetic section is accommodated at least partially by the intermediate space. In the closed position, an attractive magnetic force, which is directed substantially perpendicular to the closure direction, thereby acts both between the at least one second magnetic section and each of the at least two first magnetic sections forming the intermediate space.

    Abstract: Since a rib having a thickness substantially equal to a thickness of each of first and second thick portions is provided in a cutting portion of a zipper tape, the first and second thick portions and the rib can be bonded to an inner surface when the zipper tape is bonded to a bag body. Accordingly, when tearing a packaging bag for opening, stress concentrates on a thin portion having a small tensile strength, so that the packaging bag can be cut at a single cutting position in the thin portion. Consequently, no cutting fragment is generated. Moreover, since a cutting line is positioned by the rib when tearing the packaging bag, the cutting line is not waved, so that the packaging bag can easily be torn with a linear cutting performance.

    Abstract: The disclosure pertains to a slider zipper which includes first and second zipper profiles, typically a hinged profile and an non-hinged profile, with first and second ears extending above the respective first and second zipper profiles. A slider rides above the zipper profiles and opens the zipper by separating the ears. Typically, the slider is configured to push the non-hinged zipper profile away from the hinged zipper profiles. Similarly, typically, the ear on the non-hinged zipper profile is stiffer than the ear on the hinged zipper profile.

  • Publication number: 20120151718
    Abstract: The invention provides a fastener stringer for a hidden slide fastener Each of the fastener tapes includes a main tape body, a folded tape portion which is folded into a U-shape, and an element attaching portion. The folded tape portion includes at least two multiple-weave portions in which warp yarn forms a multiple-weave structure, and a single-weave portion arranged at least at one location of an intermediate portion of the folded tape portion. According to this, it is possible to enhance rigidity of the folded tape portion in a lateral direction of a tape, and to prevent a position of the warp yarn from being misaligned at the multiple-weave portion. Therefore, hiding performance of the hidden slide fastener can be enhanced.

  • Patent number: 8196269
    Abstract: A closure mechanism for a reclosable pouch includes a female profile having first, second, and third legs extending from a base of a first closure element. A first sealing flange is attached to each of the first and second legs, with a slit disposed through the first sealing flange to define a first sealing flap that depends from the first leg and a second sealing flap that depends from the second leg. A second sealing flange is attached to each of the second and third legs, with a slit disposed through the second sealing flange to define a third sealing flap that depends from the second leg and a fourth sealing flap that depends from the third leg. A first male profile extends from a base of a second closure element. The first male profile engages a portion of the first and second sealing flaps to form a seal therebetween when the respective male and female profiles are occluded. A second male profile extends from the base of the second closure element.

  • Publication number: 20120027322
    Abstract: A closure mechanism includes a first elongate closure member that sealing engages with a second elongate closure member and a slider. The slider slides along the first and second elongate closure members to engage or separate the first and second elongate closure members. Further, the first elongate closure member includes a first series of regularly spaced features that interacts with the slider to produce a first feedback at a first frequency and the second elongate closure member includes a second series of regularly spaced features that interacts with the slider to produce a second feedback at a second frequency. The first feedback and the second feedback are produced simultaneously when the slider is slid along the first and second elongate closure members.

  • Patent number: 8096022
    Abstract: The present invention includes a reclosable bag having first and second walls and an open top defined by first and second elongate flexible fastener strips adjacent the top of the walls. One of the fastener strip has a profile portion forming a groove and had a profile portion forming a rib. A portion of the rib is received and retained in the groove when the bag top is closed. Each of the fastener strips has a base connected to the respective walls and each of the fastener strips further has an upper edge adjacent the upper edge. The bag has a slider mounted on the strips and movable in one direction longitudinally to progressively separate the rib from the groove to open the bag, and the slider is movable in the opposite direction to progressively return the rib to a retained condition in the groove so as to close the bag.
