Investigation completed 10/09/2017.The dhr for w1504055 was reviewed and no ncmr or other issue was found related to this complaint failure mode.The kit lot was assembled in august 2015.A two year look back from 06/22/2015 to 06/22/2017 for this reported failure and or related to "packaging" for this product family (crwbp) shows no new design or manufacturing trends have been identified.The returned product showed that the inner tray tyvek lid was incidentally sealed between the outer tray and outer tyvek lid causing the inner lid to partially adhere to the outer lid.The process of sealing the inner tray between the outer tray and lid causes the inner lid to be damaged when opening the outer tray/lid.The root cause for the packaging failure on the returned product was that the inner lid was sealed between the outer tray and lid during the sealing process.The inner tray is designed to fit into the outer tray and not come in contact with the outer tray seal, however, the inner lid has excess material that is capable of falling into the seal area of the outer tray and lid.The outer tray is designed to indicate a specific corner as being the location for opening tray, due to the tray being trimmed shorter on the corner allowing a small portion of lid to be exposed.The exposed outer lid design allows the user to easily grasp the lid to open the kit.After reviewing the sealing process, it was determined that by tucking the corner of the inner lid into the outer tray prior to sealing it is possible to effectively prevent reoccurrence of the inner lid being sealed between the outer lid and outer tray.The crwbp master specifications will be updated to require the operator to seal the product using this method for all future orders.
