A fastener element for a slide fastener includes: a head portion forming at least one coupling protrusion, and at least one receiving area configured for receiving, in a closed condition of the slide fastener, a coupling protrusion of an adjacent fastener element. A first leg and a second leg extend from the head portion. Each leg forms a respective proximal portion where each leg joins the head portion, and a distal portion extending away from the proximal portion to a free end of the respective leg. A decoration bearing portion is formed with the second leg on an outer side thereof. A connecting portion is located on the distal portion of the second leg and integrally connects the decoration bearing portion to the second leg.

Systems and methods of indicating to a line worker when there is a defective zipper profile extruded onto a generally flat plastic web while moving in a feed direction in a re-sealable container production line. The system includes a sensor for detecting the defective zipper profile and a web distortion device that actuates in response to the sensor detecting the defect. The web distortion device keeps the web bunched together while it spools onto a roll support device located downstream thereby making it readily apparent to a line worker that the bunched segment contains the defective segment.

A method and apparatus for forming pouches and/or bags is disclosed. A seal and/or insert is crushed using a multiphase sealer or crusher.

A slider is provided with a tab insertion gap between an upper blade of a slider body and a free end portion of a cover body and an open and close member for opening and closing the tab insertion gap. The open and close member is disposed alongside a stop pawl body in the slider width direction, and is also disposed such that a rear end part of the open and close member can swing vertically between a passing position where a attaching shaft portion of a tab passes through and a blocking position where the passing of the attaching shaft portion of the tab is blocked. The open and close member is urged toward the blocking position. The slider can attach the tab afterward, has a stop mechanism, and can significantly reduce manufacturing costs.

A sealing tool includes an anvil and a horn, at least one of which includes a sealing surface having a gusset sealing section and a zipper sealing section, each configured differently than the other. The gusset sealing section includes a plurality of sealing beads including a gusset section barrier sealing bead having a first height and a protective sealing bead having a second height, the second height being smaller than the first height. The zipper sealing section includes a zipper section barrier sealing bead extending and a tapered section adjacent to the zipper section sealing bead, the tapered section tapering from a larger height adjacent to the zipper section sealing bead to a smaller height as a distance away from the zipper section sealing bead increases.

A luggage case including an injection molded luggage shell including a zipper assembly attached to the luggage case during the injection molding of each shell. The injection molded shell having a rim portion and having opposing inside and outside surfaces. An elongated zip member including a tape member having opposing first and second surfaces, and opposing inner and outer edges defining a width, with teeth positioned along the inner edge, and defining a length. One opposing surface of at least part of a first portion of the first tape member is in-mould-bonded to at least one opposing surface of the rim portion.

A waterproof fastener chain includes: a pair of fastener tapes made of polyester resin adjacent to each other at a given space between each side edge thereof, rows of elements respectively attached onto a main surface of the side edge of each of the fastener tapes, and waterproof coated films made of polyester resin respectively formed on a main surface of each of the fastener tapes. An outer surface of each of the waterproof coated films is flat at least at a position where a slider is to pass over, each of the waterproof coated films penetrates into irregularities on the main surface of each of the fastener tapes, a penetration depth of the waterproof coated films into a gap caused by the space of the pair of fastener tapes is not more than thickness of the fastener tapes.

An apparatus includes a first portion and a second portion. The first portion generally comprises a channel feature. The second portion generally comprises a rib feature. The rib feature is generally configured to fit within the channel feature.

A method for manufacturing a watertight zipper solves the problem of low watertight effect of the modern watertight zipper. The method includes producing a waterproof stringer tape and forming a waterproof layer by injection molding. The waterproof layer covers a lateral edge of the waterproof stringer tape and includes a plurality of recesses. The method for manufacturing the watertight zipper further includes forming an aperture in each of the plurality of recesses. The aperture extends through the waterproof layer and the waterproof stringer tape. The method for manufacturing the watertight zipper further includes forming a plurality of scoops in the plurality of recesses by injection molding.

A method and apparatus for forming pouches and/or bags is disclosed. A seal and/or insert is crushed using a multiphase sealer or crusher.
