Abstract
Abstract Portable containers suitable for use as disposable contaminated material containers are provided. The containers include a top closure including first and second closure flaps whereby the first closure flap has a central opening for filling the box and a handle member for holding it. The handle member can be inserted into a corresponding aperture of the second closure flap which protects the handle from being contaminated during use. The design also includes using an interior space defined by an internal open-ended container wrapped in a preferred thermoplastic bag. This feature enables the container to resist leakage of contaminated materials and the risk of puncture of the container by sharp objects.
