Container with crush resistant spout and method of manufacturing the same
Various embodiments are directed to a container spout secured relative to a hollow container body. The container spout includes a cap region configured to accept a container cap (e.g., a snap-on cap), and a support region positioned between the cap region and the hollow container body. The support region comprises one or more bumper rolls positioned around an exterior of the support region and one or more support protrusions extending between a bottom edge of the cap region and a bottom edge of the support region, wherein each of the one or more support protrusions defines a substantially horizontal convex curvature having a radius smaller than a radius of the container spout. The support protrusions are aligned with corners of the container, and thereby transfer axial crushing forces applied to the container spout onto the container corners to increase the axial crush resistance of the container.
