A container having a knit line. The container comprises a body defining a partially enclosed volume having an access opening defined by a neck, the neck defining a pocket. An insert is coupled to the neck. The insert comprises an outer wall configured to fit within the opening of the container and defining the periphery of the insert. The outer wall has an upper edge and a lower edge, with the upper edge including an annular lip extending radially outward to prevent the insert from being pushed too far into or through the neck. The tooth extends from the lip and is configured to insert into a notch defined by the neck of the container. An upstanding spout is located within the outer wall. A bottom wall connects the lower edge of the outer wall and the spout to form a channel between the outer wall and the spout. The lip includes a first portion having a first radius and a second portion having a second radius, wherein the first radius is larger than the second radius with the first portion forming a seal at the knit line of the container when the cover is threaded onto the neck.
