    • A reclosable bag is filled through an opening (14) defined between a back side (8') of a folded closure strip (5) secured to an inner surface of the bag on one side (9) of the bag opening, and an inner surface of the other side (10) of the bag opening. The filled bag is sealed by joining the back side (8') of the closure strip to the opposing bag wall (10) at a point (8) outboard of the closure strip and bag opening. The bag is later opened by breaking through a frangible section (7) in a folded portion of the closure strip, between mating bands (46, 48) of hooks and loops. In some cases, an extension (92, 9a, 10a) of one side of the bag forms a handle (4) or a fitment; in particular, funnels (80) can be formed from integral extensions of the closure strip (5), integral extensions of the bag-making material, or from a discrete preform which is joined to the construction.

    • Touch fasteners useful for bags, packaging and other products as well as novel manufacturing of products incorporating such fasteners are described. A composite touch fastener has an elongated, sheet-form resin substrate, a fibrous loop strip (104) partially encapsulated in, or otherwise permanently attached to, resin of the substrate, and an array of loop-engageable fastener elements (106) integrally molded with resin of the substrate. The loop strip forms a discrete band of hook-engageable, free-standing loops along the length of the substrate and has a substantially constant fiber density across its width. The array of fastener elements is arranged in a discrete band of fastener elements extending longitudinally along the substrate. The fastener product is useful as a repeated use bag closure, with a pair of grooves and a graspable rib (132) integrally molded into the substrate between the fastener elements and loops. The center portion of the closure seals the bag until it is torn away to expose the mating bands of loops and fastener elements. Methods and apparatus are disclosed for continuously molding the resin of the substrate while permanently attaching preformed material, such as loop material staked in discrete regions, to resin of the substrate, and for forming discrete bags incorporating the bag closure. Methods of applying recloseable touch fasteners, e.g. hook and loop fasteners, to sheet or film include vertical form and fill and horizontal form and fill packaging and pouch making.
    • 描述了用于袋,包装和其他产品的触摸紧固件以及结合这种紧固件的产品的新颖制造。 复合接触紧固件具有细长的片状树脂基材,部分地封装在基材的树脂中或以其他方式永久固定在基材的树脂上的纤维环带(104)和一体的可环接的紧固件元件(106)阵列 与基材的树脂。 环带形成沿着衬底的长度的钩接合的独立环的离散带,并且在其宽度上具有基本上恒定的纤维密度。 紧固件元件的阵列布置在沿衬底纵向延伸的紧固元件的离散带中。 紧固件产品可用作重复使用的袋封闭物,其具有一对凹槽和在紧固件元件和环之间整体模制到基底中的可抓握肋(132)。 封闭件的中心部分密封袋,直到其被撕开以露出环和紧固件元件的配合带。 公开了用于连续模塑基材的树脂的方法和装置,同时将预先形成的材料(例如分散在不连续的区域中的环状材料)永久地附着到基材的树脂上,并且用于形成结合有袋封闭件的分立的袋。 应用可再密封触摸紧固件的方法,例如 钩和环紧固件,片材或薄膜包括垂直形式和填充和水平形式并填充包装和袋制造。
