Abstract

A hinged instrument tray and disposable receptacle for contaminated waste. The tray is formed in two halves which are joined by a hinge so that the two halves of the tray can be opened and laid side-by-side thereby permitting access to the instruments contained within the tray. Contaminated materials or instruments can be collected in one or both halves of the tray so that when use of the instruments or materials is completed, the two tray halves can then be folded one on top of the other and the two tray halves can then be permanently locked together so as to enclose the contaminated instruments or materials therewithin, thereby forming a secure, tamper-proof disposable receptacle.
