A packaging device including a container (10, 10') and a closure (12, 12'), the container (10, 10') comprising: a base; a body extending in a direction away from the base and establishing a longitudinal axis of the container; and, a neck finish (18, 18') extending in a direction away from the body, and including a spout, a radially outer surface having at least one closure engagement feature projecting away from the outer surface; and, a radially inner surface, the spout having an axial length that varies about a circumference of the neck finish (18, 18') and establishing an axial end surface of the neck finish (18, 18'), the axial end surface forming a plane disposed at a non-perpendicular angle (θ 1) with respect to the longitudinal axis, and the radially inner surface including a sealing surface (36, 36') located axially between the axial end surface and the body and disposed at an angle (θ 2, θ 3) with respect to the longitudinal axis, the closure (12, 12') comprising: an annular base wall disposed about the longitudinal axis and facing the axial end surface of the neck finish; a radially outer wall extending in a direction away from the base wall and facing the radially outer surface of the neck finish; a radially inner wall radially spaced from the radially outer wall and extending in a direction away from the base wall, the radially inner wall facing the radially inner surface of the neck finish; and, a transverse wall (46, 42') extending radially inwardly from the radially inner wall and axially spaced from the base wall, characterized in that the transverse wall defines a sealing surface (48, 48') configured to seal against the sealing surface of the container. the container (10, 10') comprising: a base;
