Abstract
A spill-resistant spout and method of injection molding a spill-resistant spout. The spill-resistant spout includes a conduit portion having an exit aperture in fluid communication with a central channel; and a seal portion having a bottom surface, the seal portion secured to the conduit portion and in fluid communication with the central channel, the bottom surface comprising at least two intake apertures configured to receive foodstuffs from a container. The use of multiple intake apertures increases the surface tension on the foodstuffs attempting to pass through the intake apertures while maintaining or increasing the total flow volume of foodstuffs through the spill-resistant spout. Additionally, the barrier qualities of the spill-resistant spout can be enhanced by providing one or more discrete layers of thermoplastic material and one or more layers of barrier material within at least one portion of the spill-resistant spout.
