Abstract: Two types of disposable pans made from a paper sheet material by press means are disclosed, particularly designed to prevent its paper configuration from easily deforming and/or to prevent its bottom portion from easy burning or scorching. The one type includes at least two parts, a bowl-like concave part having a bottom portion and an opening divergent part extended upwards from said concave parts. This type necessitates a specific supporting means when used with a cooking oven. The another type additionally includes a flange part interposed between said two parts and can be used without any supporting means. In order to prevent the paper configuration from easy deforming, a plurality of folds are provided on the opening divergent part to have the overlapped width small, and/or a synthetic resin is laminated on said paper sheet material.
