  • Patent number: 6491432
    Abstract: A slider device is disclosed for use with a resealable package. The slider device includes structure for preventing or minimizing the likelihood that the slider device can be removed from the resealable package. In one embodiment, the slider device includes a top wall and first and second sidewalls depending from the top wall. The first sidewall has a barb member extending inwardly toward the first closure profile of the resealable closure mechanism. The barb member is constructed and arranged to engage the first closure profile in response to a pulling force on the slider device away from the resealable closure mechanism. In another embodiment, the first sidewall also includes a hook construction defining a flange to slidably cover a shoulder of the first closure profile. The hook construction and flange define an offset that is constructed and arranged to engage the shoulder of the first closure profile in response to a pulling force on the slider device away from the resealable closure mechanism.

  • Patent number: 6004032
    Abstract: Closure arrangements for use with flexible packages include a zipper-type closure, which, after initial sealing, if access is gained to a package interior, the arrangements provide evidence of that access. In certain embodiments, a closure with mating male and female profiles is used which, after initial sealing of the package, if access is desired to the package interior, one of the male or female profiles breaks, to prevent a resealing of the package. In other embodiments, after initial mating of the male and female closure profiles in order to seal the package, if access is desired to the package interior, the package walls are torn in order to gain access. In other embodiments, after initial sealing of the package by mating of the male and female profiles, if access is desired to the package interior, the male and female profiles are deformed, such that they no longer mate to provide a secure closure. Methods for using the arrangements herein are also provided.
