A blank () comprising a row of body panels (P-P), and a row of end closure panels (P-P) extending substantially parallelly to the row of body panels (P-P), whereof each end closure panel (P-P) has an edge (E-E), and whereof each of the second (P) and fourth (P) end closure panels has oblique lines of weakness (S, S, S, S) which divide its panel into a central sub-panel (P, P) adjacent the corresponding second or fourth body panel (P, P) and two end sub-panels (P, P, P, P) adjacent the corresponding edges (E, E), wherein the end sub-panels (P, P, P, P) bulge away from its corresponding edge (E, E). A container formed from the sheet material blank and a method of forming the container is also described. The method involves the use of a mandrel cap including a bearing surface () and a bridging surface portion () substantially flush with said bearing surface (), and extending between recessed surface portions () at respective opposite sides of said bridging surface portion ().

Container, blank, mandrel and method of forming the container

A dosing apparatus 1 includes a material flow control arrangement 2 including vertical ducting 4 having co-axial therewith a vertically reciprocatory rod 5 mounting at its ends inlet and outlet valve closure plugs 6a and 6b. The upper and lower end zones of the ducting 4 define respective circular-cylindrical inlet and outlet 13a and 13b bounded by respective circular-cylindrical valve seats 14a and 14b in which the plugs 6a and 6b are sliding fits. Mounted on at least one horizontal extension piece 4d of the ducting 4 is at least one dosing pump 16. When the outlet 13b is closed by the plug 6b, the cross-section of the inlet 13a is unobstructed; similarly, when the inlet 13a is closed by the plug 6a, the cross-section of the outlet 13b is unobstructed. Furthermore, in an intermediate position of the rod 5, the cross-sections of both the inlet 13a and the outlet 13b are unobstructed, so that passage of a cleaning fluid through the ducting 4 is facilitated.
