NGWAFOR & PARTNERS SARL, The House of Gideon, Golf/Bastos Quarter, Opposite The American Embassy, Entrance-Saint John Paul II Boulevard, B.P. 8211, YAOUNDE (CM). (57) A filter plate subframe (1) for a filter plate frame assembly having a filter plate frame and a filter plate subframe slidably receivable therein. The subframe comprises separate periphery segments (2a, 3a, 4a, 5a, 6a) attached to each other so as to form a continuous, generally rectangular periphery region (la) with flank sides and end sides. The flank sides (2, 3) have a linear density lower than that of the end sides (4, 5), and the end sides (4, 5) have a bending stiffness higher than that of the end flank (2, 3), while either or both of the first end side (4) and the second end side (5) are provided with a reinforcement bar (4b, 5b) for increasing the bending stiffness said end sides (4, 5). A supporting surface is provided on a first planar side (lc) of periphery segments forming the flank sides (2, 3) the supporting surface. ________________________________________ (11) 21283 Consulter le mémoire (51) B65D 41/34 (2018.01) ; B65D 50/00 (2018.01) (21) 1202300171 - PCT/IB2021/059918 (22) 27/10/2021
