Patent ID: 8236398

Claim:
A cup-type polypropylene container obtained by compression-molding a polypropylene and having at least a body portion and a bottom portion, wherein the body portion has a thickness of not larger than 1.0 mm and a value K 1 in the body portion represented by the following formula, K 1 =P 1 /P 2 wherein P 1 and P 2 are, respectively, a peak intensity at a diffraction angle 2 θ=14.5° and a peak intensity at a diffraction angle 2 θ=17.2° in the peak intensity distribution in the x-direction of a Debye ring obtained by measuring the diffraction intensity while defining the circumferential direction of a test piece cut out from the body portion of the container to be x, the direction of height thereof to be y, and by causing x-ray to fall perpendicularly to the xy-plane of the test piece, lying in a range of 0.5 to 1.0 and a value K 2 represented by the following formula, K 2 =Hβ 1 /( Hβ 1 +Hα 1 +Hα 2 +Hα 3 ) wherein Hβ 1 , Hα 1 , Hα 2 and Hα 3 are values obtained by subtracting the diffraction intensity of an amorphous portion from a peak intensity at a diffraction angle 2 θ=16.3° , and from a peak intensity at a diffraction angle 2 θ=14.5° , and from a peak intensity at a diffraction angle of 17.2° and from a peak intensity at a diffraction angle of 18.8° in the peak intensity distribution in the x-direction of a Debye ring obtained by measuring the diffraction intensity while defining the circumferential direction of a test piece cut out from the body portion of the container to be x, the direction of height thereof to be y, and by causing x-ray to fall perpendicularly to the xy-plane of the test piece, which is larger than 0 in at least part of the body portion.
