A MASKING PACKAGE

摘要

A masking package is provided to mask medical or hypodermic syringes or vials for syringes. This sort of masking package may be used in blind drug trials where the participant must not be able to identify the drug being used. The masking package is comprised of an opaque housing (102, 104) and an adaptor element (122) for fixing the syringe or vial into the housing (120. 104). The housing has two portions (102, 104) which can move relative to each other.
