    • A fastener includes first and second tracks. The first track includes a first profile, and the second track includes a second profile for interlocking with the first profile. The fastener extends between opposing ends. The first and second profiles at each of the opposing ends are sealed to each other using a laser. In one embodiment, the fastener is initially continuous and is subsequently divided into segments by simultaneously cutting and sealing the fastener at spaced target locations using the laser. The segments are associated with respective plastic bags. At each of the target locations, the laser directs a laser beam at the fastener such that the laser beam cuts through the first and second profiles and simultaneously seals the first and second profiles to each other on opposite sides of the cut. The seals on the opposite sides of the cut terminate respective ends of adjacent ones of the segments.
    • 紧固件包括第一和第二轨道。 第一轨道包括第一轮廓,并且第二轨道包括用于与第一轮廓互锁的第二轮廓。 紧固件在相对端之间延伸。 每个相对端的第一和第二轮廓都使用激光彼此密封。 在一个实施例中,紧固件最初是连续的,并且随后通过使用激光器在间隔开的目标位置处同时切割和密封紧固件而被分成段。 这些片段与相应的塑料袋相关联。 在每个目标位置处,激光器将激光束引导到紧固件处,使得激光束切割穿过第一和第二轮廓并且同时在切口的相对侧上彼此密封第一和第二轮廓。 切口相对两侧的密封件终止相邻部分的相应末端。

    • A plastic bag comprises first and second opposing panels, a reclosable zipper, and a slider. The first and second opposing panels are fixedly connected to each other along a pair of sides and a bottom bridging the pair of sides. The reclosable zipper extends along a mouth formed opposite the bottom. The zipper includes a first track with a first profile and a second track with a second profile. The first and second profiles are releasably engageable to each other. The slider is slidably mounted to the zipper for movement between a closed position and an open position. The first and second profiles are engaged to each other while the slider is in the closed position, and the first and second profiles are disengaged from each other in response to movement of the slider from the closed position to the open position. To prevent the slider from going past the ends of the zipper and to provide adequate end strength that resists stresses applied to the profiles during normal use of the bag, end terminations in the form of posts pass through the male and female tracks adjacent to the ends of the zipper. To retain the posts on the zipper, each of the posts includes enlarged heads at its opposing ends.
    • 塑料袋包括第一和第二相对面板,可再闭合拉链和滑块。 第一和第二相对面板沿着一对侧面和桥接该对侧面的底部彼此固定连接。 可重新闭合的拉链沿着与底部相对形成的口延伸。 拉链包括具有第一轮廓的第一轨道和具有第二轮廓的第二轨道。 第一和第二轮廓可释放地彼此接合。 滑块可滑动地安装到拉链上,用于在关闭位置和打开位置之间运动。 第一和第二轮廓在滑块处于关闭位置时彼此接合,并且响应于滑块从关闭位置移动到打开位置,第一和第二轮廓彼此脱离。 为了防止滑块经过拉链的端部并且提供足够的端部强度以抵抗在正常使用袋子期间施加到型材上的应力,柱的形式的端部端部穿过与端部相邻的阳和女性轨道 的拉链。 为了将柱保持在拉链上,每个柱在其相对端包括扩大的头部。

    • A plastic bag comprises opposing body panels fixedly connected to each other along a pair of sides and a bottom bridging the pair of sides. A reclosable zipper extending along a mouth portion formed opposite the sealed bottom of the plastic bag. The zipper is preferably free of graspable upper pull flanges in order to best accommodate a slider and inhibit operation of the zipper without the slider. The slider is mounted to the zipper for movement between a closed position and an open position. The zipper is closed while the slider is in the closed position. The zipper is opened in response to movement of the slider to the open position. To inhibit tampering with the contents of the bag, the bag includes a tamper-evident feature. In one set of embodiments, the tamper-evident feature initially maintains the slider in the closed position and allows the slider to move away from the closed position toward the open position in response to removing or breaking the tamper-evident feature. In another set of embodiments, the tamper-evident feature initially maintains a mouth portion of the plastic bag in a folded position and allows the mouth portion to be unfolded in response to removing or breaking the tamper-evident feature.
    • 塑料袋包括沿着一对侧面彼此固定连接的相对的主体面板和桥接该对侧面的底部。 沿着与塑料袋的密封底部相对形成的口部延伸的可再闭合的拉链。 拉链优选地没有可抓握的上拉法兰,以便最好地容纳滑块并且禁止拉链的操作而不用滑块。 滑块安装在拉链上,用于在关闭位置和打开位置之间移动。 当滑块处于关闭位置时,拉链关闭。 拉链响应于滑块移动到打开位置而打开。 为了防止篡改袋的内容物,袋子包括防窃启特征。 在一组实施例中,防窃启特征最初将滑块保持在关闭位置,并且允许滑块响应于去除或断开防窃启特征而从关闭位置移动到打开位置。 在另一组实施例中,防窃启特征最初将塑料袋的口部保持在折叠位置,并且允许口部分响应于去除或破坏防篡改特征而展开。
