  • the present invention relates to the technology for detecting when an object has been shaken or subjected to an impact, and more particularly to a device that can be provided on the outside of a package or container to enable the buyer to identify whether or not the goods within the package/container have been subjected to shaking or an impact, without opening the package/container.
  • the shipped goods are very susceptible to being impacted and shaken during transit. Since the goods are packaged in an envelope or inside a container, such as a box, and are typically not opened until the deliverer has departed, the buyer or recipient (hereafter just "recipient") of the package is not able to know, at the time of delivery, if the goods have been damaged. If the recipient subsequently opens the package and finds out that the goods have been damaged, it is inconvenient for the recipient to return the goods. The return process prolongs the time it takes for a recipient to ultimately receive and enjoy the ordered goods.
