Abstract: A high voltage electrical packaging box structure includes a case member having an opening portion, and a cover member which is detachably attached to the case member so as to cover the opening portion of the case member. The case member is installed so that a plane of the opening portion is inclined with respect to a horizontal plane. In the high voltage electrical packaging box structure, a pawl member is provided on one of the case member and the cover member, and a receiving member, which engages with the pawl member, is provided on the other one of the case member and the cover member.
Abstract: A separator for an alkaline storage battery includes a plurality of polyolefin resins. The polyolefin resins include a first polyolefin resin that is sulfonated, and a second polyolefin resin that is sulfonated. The degree of sulfonation of the first polyolefin resin is different from that of the second polyolefin resin. Thus, a novel separator having high liquid retention properties and high air permeability, and an alkaline storage battery using the same can be obtained.
