Seal testing device and method

摘要

A device for testing the integrity and strength of a seal. The device includes a first enclosure member adapted to receive a pre-sealed package formed of two films joined together to form a continuous seal, the two films extending outwardly of the seal to define a marginal edge portion of the package. A second enclosure member adapted to cooperate with the first enclosure member upon demand is also provided to seal the marginal edge portion in spaced relation to the continuous seal of the pre-sealed package. The device also includes a fluid injection member adapted to cooperate with the first and second enclosure members by injecting a fluid between the two films after the marginal edge portion of the pre-sealed package has been sealed. An opening located outwardly of the continuous seal of the pre-sealed package and inwardly of the seal created by the first and second enclosure members is provided through which the fluid may be injected between the two films of the package. Additionally, the device includes a sensor located in proximity to the pre-sealed package to sense any passage of the fluid through the continuous seal into the pre-sealed package.
