<p>PROBLEM TO BE SOLVED: To provide a container which is free from any deformation or cracks by the pressure from an upper part, easy in reducing the volume during the disposal, and easy in handling by forming a resin composition containing styrene resin and thermoplastic resin of specified wt.%, and forming the container having an opening part in which the thickness and the drawing ratio of a bottom part are specified and provided with the specified buckling strength. SOLUTION: A container having an opening part is preferably 1-50 kg in buckling strength, 0.1-3 mm in thickness of a bottom part, and 2 or under in drawing ratio (depth/width or diameter). A resin composition to obtain the container contains, by weight, 40-97% styrene resin, and 60-3% thermoplastic resin, i.e., a polyolefin resin of 100-300 deg.C in melting point. At least one kind of compatibilizer can be blended. The container can be obtained by a method to form a sheet obtained by the extrusion method through a circular die or an injection molding of the resin composition after pellets consisting of the resin composition are melted and kneaded by a regular extrusion machine.</p> |
