The invention discloses a sponge sheet. A plurality of ribs (10) are formed at a predetermined pitch on a sponge sheet (1) formed by extrusion molding a rubber or a thermoplastic elastomer, and the plurality of ribs (10) protrude from one surface (1a) in the thickness direction and extend in a predetermined direction. When the height of the rib (10) is h, the pitch of the rib (10) is x, and the radius of the arc surface constituting the outer surface of the rib (10) is R, the height of the rib (10), the pitch of the rib (10), and the radius of the arc surface constituting the outer surface of the rib (10) are set so as to satisfy the relationship of 12.595 + (-9.5 * h) + (-38.1 * R) + (16.7 * x) > 0. Even if a plurality of sponge sheets are stored in a stacked manner, the sponge sheets are difficult to adhere to each other, so that the workability of taking a required number of sponge sheets from the uppermost surface is improved.
本发明公开了一种海绵片。在对橡胶或热塑性弹性体进行挤压成形而制成的海绵片(1)上以规定间距形成有多条肋条(10),多条肋条(10)从厚度方向上的一个面(1a)突出且沿规定方向延伸。在将肋条(10)的高度设为h、将肋条(10)的间距设为x、将构成肋条(10)的外表面的圆弧面的半径设为R时,肋条(10)的高度、肋条(10)的间距、构成肋条(10)的外表面的圆弧面的半径设定为满足12.595+(-9.5×h)+(-38.1×R)+(16.7×x)>0的关系。即使以堆叠的方式保管多张海绵片,海绵片彼此之间也难以粘连,从而提高从最上面拿取所需张数的海绵片时的作业性。
