1. A container for enabling fluid flow, wherein the container comprises a flexible bag with at least a first and a second film sealed to one another, the container further comprising:
an inlet port;
an outlet port; and
a fluid conduit to put the inlet port in fluid communication with the outlet port, the fluid conduit comprising
one or more deflection sections,
a connection section located upstream from at least one of the one or more deflection sections, and
a successive connection section located downstream from the at least one or more deflection sections,
wherein the fluid conduit has a maximum width in a direction of the fluid flow through the fluid conduit,
wherein at least one of the one or more deflection sections further comprises an entry section and an exit section, each respective exit section being arranged downstream, in the direction of the fluid flow, from each respective entry section,
wherein the entry section includes an inner edge having a nonlinear shape with a concave curve trend in a first portion and a convex curve trend in a second portion and an outer edge having a linear shape, wherein the outer edge contacts and continues straight from an outer edge of the connection section,
wherein a width of the fluid conduit decreases along the direction of the fluid flow through the entry section over a first distance, from the maximum width to a narrower width, wherein a decrease through the entry section is non-uniform along the direction of the fluid flow through the entry section,
wherein the exit section includes an inner edge having a linear shape corresponding to a line segment positioned at an angle with respect to an outer edge of the exit section, wherein the outer edge of the exit section contacts and continues straight from an outer edge of the successive connection section, and
wherein the width of the fluid conduit increases along the direction of the fluid flow through the exit section over a second distance, from the narrower width to the maximum width.
