According to an embodiment of the present invention, the symbol score 220 may be a designed a L symbol, and the designed a L symbol score is a connected score, that is, as shown in fig. 1, there is no protrusion in the whole designed a L symbol region, and at this time, the cross section of the symbol score 220 is as shown in fig. 3. the inventors found that if a small triangular included angle protrusion is formed in the a L symbol score region, the entrainment sticking is easily formed due to a small contact area with the tablet itself, and the probability of the sticking is significantly reduced by designing an included angle full cut, and further, as shown in fig. 3, the maximum width W1 of the cross section of the digital score 210 is also not particularly limited, and as needed, the maximum width W1 of the symbol score may be selected, for example, from 0.3 to 0.34mm, specifically too small, for example, from 0.3mm, 0.31mm, 0.32mm, 0.33mm, 0.34mm, and the maximum width W of the cross section of the symbol score 220 may be selected, as 0.3mm, 0.31mm, 0.32mm, 0mm, 0.33mm, 0.34mm, and as needed, and as shown in the maximum width W of the adhesive face may be selected, and as shown in fig. 3, and 3621 mm, the maximum R8 mm, the drawing, the maximum width W8 mm, the range of the adhesive may be easily adjusted, the adhesive may be changed from 0.8 mm, the range of the adhesive line 0.8 mm, the range of the adhesive line 8mm, the range of the.

Further, as shown in fig. 1, length L of a region where digital score 210 is located is not particularly limited in percentage of maximum cross-sectional diameter Φ of score portion 200 in the horizontal direction, and may be selected according to actual needs, for example, 56 to 60%, specifically, 56%, 57%, 58%, 59%, 60%, where maximum cross-sectional diameter Φ of score portion 200 is diameter of cylindrical portion (same below), the inventors found that the tablet surface is in a shallow arc shape, and points of the arc surface are subjected to different pressing forces, and adjust within this ratio range, force on the score is not affected, and beyond this range, force on the score is not uniformly applied, so as to cause sticking risk, and by adjusting W2 and L, probability of sticking is reduced, and by adjusting distance of central line a of a central line a of an excessively small region where digital score 210 is located in the horizontal direction, from central line b of maximum cross-sectional longitudinal axis of score portion 210, to central line b of maximum cross-sectional diameter of score portion 200, and by adding 0.3%, and by this invention, and adjusting force on the score portion, for example, by a certain number, a number, a number.

Further, as shown in fig. 1, length L of the area where the symbolic score 220 is located is not particularly limited in percentage of the maximum cross-sectional diameter of the score portion 200 in the horizontal direction, and may be, for example, not less than 31.8%, the inventors found that the tablet surface has a shallow arc shape, the points of the arc surface are subjected to different pressing forces, and the adjustment in the range of the ratio does not affect the force applied to the arc surface, the adjustment in the range of the ratio causes uneven stress on the symbolic score to cause the sticking risk, and the adjustment in the range of the ratio causes uneven stress on the symbolic score 200, and the adjustment in the range of the ratio causes uneven stress on the symbolic score 220, and the adjustment in the range of the ratio causes uneven stress on the top of the arc surface, and the arc surface has a width of the vertical line of the arc surface, and the point of the arc surface, and the arc surface is adjusted to be, and the ratio of the vertical line of the arc surface to the notch 200 is adjusted to be, and the arc surface is adjusted to have a smaller stress on the vertical line of the arc portion 200, and the arc portion may not subjected to the smaller, and the smaller number of the smaller than the smaller number of the smaller.

Further, as shown in fig. 1, the percentage of the width W4 of the area where the score 21 is located in the vertical direction to the maximum cross-sectional diameter of the score part 200 is not particularly limited, and can be selected by those skilled in the art according to actual needs, for example, it can be 66-68%, and specifically, it can be 66%, 66.5%, 67%, 67.5%, and 68%. The inventor finds that the surface of the tablet is in a shallow arc shape, the extrusion force on each point of the arc surface is different, the stress of the arc surface cannot be influenced by adjusting within the proportion range, and the notch is unevenly stressed by adjusting beyond the range to cause sticking risk.

The invention will now be described with reference to specific examples, which are intended to be illustrative only and not to be limiting in any way.
