    • The bag for receiving refuse may include a bag body, the bag body including an inside surface, an outside surface, and a rim defining a mouth. The bag may also include a first strip of material disposed on the inside surface of the bag body proximate the rim. The strip may include an inside surface, an outside surface that faces the inside surface of the body, a top edge, and a bottom edge. The bag may also include a front wall, a back wall, and a hem, the hem including a drawstring. The strip may include a printed design. The design could be letters, numbers, pictures, writing, or any other design. When the bag is inserted into a trash receptacle such that the rim of the bag is folded over the rim of the receptacle, the printed design is visible from outside the receptacle.
    • 用于接收垃圾的袋可以包括袋体,袋体包括内表面,外表面和限定嘴的边缘。 袋子还可以包括设置在靠近边缘的袋体的内表面上的第一条材料条。 带材可以包括内表面,面向主体内表面的外表面,上边缘和底边。 该袋还可以包括前壁,后壁和下摆,下摆包括束带。 该条带可以包括印刷设计。 设计可以是字母,数字,图片,书写或任何其他设计。 当将袋子插入垃圾容器中使得袋子的边缘折叠在容器的边缘上时,印刷设计从容器外部可见。

    • A flexible bag comprises flexible sheet material assembled to form a semi-enclosed container having an opening. The bag has a drawtape closure for sealing the opening. The sheet material of the drawtape closure exhibits elastic-like behavior along at least one axis. The sheet material of the drawtape closure comprises a first region and a second region. The first region and said second region are comprised of the same material composition and each has an untensioned projected pathlength. The first region undergoes a substantially molecular-level deformation and the second region initially undergoes a substantially geometric deformation when the sheet material is subjected to an applied elongation in a direction substantially parallel to an axis in response to an externally-applied force upon the sheet material of the drawtape closure.
    • 柔性袋包括组装成形成具有开口的半封闭容器的柔性片材。 该袋具有用于密封开口的抽屉盖。 拉伸盖的片材沿着至少一个轴线呈现弹性状态。 拉伸盖的片材包括第一区域和第二区域。 第一区域和第二区域由相同的材料组成构成,并且每个都具有未张紧的投影路径长度。 第一区域经历基本上分子水平的变形,并且当片材材料响应于对片材的外部施加的力而在基本上平行于轴线的方向上施加延伸时,第一区域经历基本上几何变形 的抽屉盖。

    • A plastic draw tape bag includes a non-destructive hem seal which runs along the width of the bag to secure the draw tape. The seal is created by bonding two layers of film by using an adhesive, a hot seal, or a coextruded film. When stressed by adequate forces, the seal will partially open without tearing the film. However, it will open only to the extent that the load exceeds the seal strength. Once the film absorbs the load and the stress is relieved, the seal will stop opening and the remaining portion of the seal will remain intact. Thus, the stress concentration is dissipated without tearing the film at or near the seal. As a result, the bag will fail only when the forces on the bag exceed the load bearing limit of the film.
    • 塑料拉带袋包括沿着袋的宽度延伸以固定拉带的无损折边密封件。 通过使用粘合剂,热密封或共挤出膜粘合两层膜来产生密封。 当受到足够的力量的压力时,密封将部分打开而不撕裂胶片。 但是,只有在负载超过密封强度的情况下才会打开。 一旦薄膜吸收负载并释放应力,密封件将停止打开,并且密封件的剩余部分将保持不变。 因此,应力集中不会在密封处或附近撕裂薄膜而消散。 因此,只有当袋上的力超过胶片的承载极限时,包才会失效。

    • A draw tape bag comprising: (a) two panels formed from a thermoplastic material, the sides of said panels being joined on three sides and open on the fourth side to form a top in said bag; (b) a hem portion of each panel being folded over adjacent said top to form a tubular hem; (c) draw tapes in each tubular hem secured at said sides of said panels, said draw tapes being characterized as a multilayer structure having at least two layers wherein one layer is sealable to a panel and is characterized as having sealability to the thermal plastic panels greater than at least one of other layers of the draw tape and also characterized as having strength less than said other layer of the draw tape; (d) a seal between each hem portion and the adjacent panel across the width of said bag below said draw tape; and (e) an opening in said hem portion for accessing said draw tape.
