    摘要： A carton includes a longitudinally extending sidewall portion which circumscribes and defines a carton cross-section interior and is provided with at least two tiers of integral support ledges which extend into the carton interior. Each support ledge is formed from a pair of slits in the sidewall which extend integrally from and between spot creases formed in the sidewall, and each support ledge has at least two interior spot creases positioned between the end spot creases. The carton may have a rectilinear cross-section and longitudinally extending corner edges formed by adjacent sidewalls, and the slits which form the support ledge may be offset with respect to the corner edge formed by the adjacent sidewalls from and between which the slits extend.

    摘要翻译： 纸箱包括纵向延伸的侧壁部分，其外接并限定纸板横截面内部，并且设置有延伸到纸板箱内部的至少两层一体的支撑凸缘。 每个支撑凸缘由侧壁中的一对狭缝形成，所述一对狭缝从形成在侧壁中的斑点之间和之间整体延伸，并且每个支撑凸缘具有位于端点折痕之间的至少两个内部斑点折痕。 纸箱可以具有由相邻侧壁形成的直线横截面和纵向延伸的角部边缘，并且形成支撑凸缘的狭缝可以相对于由狭缝延伸的相邻侧壁形成的角边缘偏移。
