Abstract
Abstract A nappy or diaper changing bag is made from a soft quilted plastic material and comprises two closable storage compartments connected at their undersides by a mat on which the baby being changed is placed. Foldable end flaps support the baby's head and legs, respectively. Nappies or diapers and ointments can be stored in the compartments and feeding bottles in wells provided in the end of one of the compartments. During transportation of the bag, the flaps are folded over the mat and one compartment is placed over the other compartment and held in place by fastenings. Handles attached to the lower part of the bag enable it to be carried.
