DIRECTIONAL DISPENSING VALVE

摘要

A flexible, pressure-openable dispensing valve (20, 20A, 20B, 20C, 20D, 20E, 20F, 20G) has a mounting base (32, 32A, 32B, 32C, 32D) and has an outwardly extending head having at least three peripheral walls (51, 52, 64; 5 IB, 52B, 64B; 51C, 52C, 64C; 5 ID, 52D, 64D) that each projects forwardly from the base (32, 32A, 32B, 32C, 32D). The head (30) also includes an end wall (68, 68B, 68C, 68E, 68F, 68G) that extends between, and connects, the outer margins of the peripheral walls (51, 52, 64; 5 IB, 52B, 64B; 51C, 52C, 64C; 5 ID, 52D, 64D). The end wall (68, 68B, 68C, 68E, 68F, 68G) has a dispensing orifice (70, 70A, 70B, 70C, 70E, 70F, 70G) surrounded by a spreading surface.
