The invention relates to a multitier packaging box assembly designed specifically for storage and transportation of products in a manner to allow excess moisture to escape so as to maintain quality of the stored products. Further, a unique locking mechanism keeps the box intact while serving the food wherein all the tiers can be accessed simultaneously. The multitier box/container assembly is provided with multitier ventilation to allow excess moisture or condensation to escape from each tier via the cut out/channel provided at the base of each upper tier, to allow the steam to traverse from inside the box to outside the box thereby minimizing condensation and spoiling the intended quality of the food. The intended path of such ventilation includes form bottom tier to the upper tier through the cut outs provided at the bottom of the upper tier to outside.
