发明名称 Display card with concave panel
摘要 A display support in which a back wall is provided with a pair of horizontal walls; and a front concave wall which is a smooth concave curve without any folds therein extending continuously in an arc from the outer edge of one horizontal wall to the outer edge of the other horizontal wall. A fold line in the back wall at a specific location which is substantially equal to the sum of the lengths of the two horizontal walls on the back wall minus the linear length of the front concave wall divided by two, a minimum of indenting of the back wall is obtained in order to obtain the smooth contour of the front concave wall. This fold line in the back wall may be provided adjacent the top horizontal wall or adjacent the bottom horizontal wall at the specific location with respect to the respective walls above noted.
