PROBLEM TO BE SOLVED: To provide a dividable tablet equipped with no segmentation groove of a V-shaped cross section and having neither edge nor corner which form starting edge of tablet wear or tablet rim part lack.SOLUTION: About the X-axis and the Y-axis orthogonal to each other in the radial direction of a tablet body and the Z-axis in the direction increasing the thickness of the tablet body, an upper rim part (24) of the tablet body draws an inclination line gradually increasing in the Z-axis direction from a lower rim part (24L) where crossing with the X-axis to a higher rim part (24H) where crossing with the Y-axis, a pair of protruded parts (25, 25) forming a convex curved surface (28Y) protrudes in the Z-axis direction beyond the upper rim part (24) to form between protruded parts (25, 25) a valley (29) following the X-axis. An inclination peripheral surface (30) and a ridge line relevant part (31), surrounding the protruded parts (25, 25), are formed in the circumferential direction to be circular all over the whole perimeter of the tablet body (22) without intermittence, a lower inclined surface part (30L) of the inclination peripheral surface (30) is put between both the ends of the valley (29) and the lower rim part (24L) and the valley bottom part of the valley (29) is positioned at the upper side of the lower rim part (24L).COPYRIGHT: (C)2012,JPO&INPIT【課題】断面V形の割溝を設けておらず、錠剤の摩損や錠剤縁部の欠損の起端となるエッジや角部を全く有しない分割可能な錠剤を提供する。【解決手段】錠剤本体の径方向で相互に直交するX軸及びY軸と、錠剤本体の厚さを増す方向のZ軸に関して、錠剤本体の上縁部(24)がX軸に交差する低位縁部(24L)からY軸に交差する高位縁部(24H)に至り次第にZ軸方向に向けて上り傾斜ラインを描き、凸状曲面(28Y)を形成する一対の隆起部(25,25)が上縁部(24)よりもZ軸方向に突出し、隆起部(25,25)の間にX軸に沿う谷部(29)を形成する。隆起部(25,25)を囲む傾斜周面(30)と稜線相当部(31)が周方向に途切れることなく錠剤本体(22)の全周にわたり環状に周設され、斜周面(30)の低位斜面部(30L)を谷部(29)の両端と低位縁部(24L)の間に介在させ、谷部(29)の谷底部を低位縁部(24L)よりも上方に位置させている。【選択図】図1
