Abstract: A flexible container (10) is disclosed. The flexible container (10) includes four panels (18, 20, 22, 24), each panel comprising a flexible multilayer film. Each flexible multilayer film is composed of a polymeric material. The four panels form (i) a body, (ii) a neck, and (iii) a handle. The handle (12) has an upper handle portion (12a) and a pair of spaced-apart legs (13, 15). The legs extend from the upper handle portion to the body on opposing sides of the neck. The flexible container includes a fitment (70) sealed to the neck. The flexible container includes a dispensing pump (100) attached to the fitment. The flexible container can provide a metered dose from a dispensing pump and the dispensing pump can also function as a handle to hand-carry the flexible container.
