A closure system including a cap and a spout, where the cap and/or spout contain at least one discrete layer of barrier material. In one example, the spout includes a conduit and a seal member, the conduit being arranged about an imaginary axis and the seal member having one or more surfaces configured to be secured to a container. The cap includes an inner circumferential surface, the inner circumferential surface arranged to encompass the conduit. The cap also includes a first discrete layer of thermoplastic resin and a first discrete layer of barrier material and the seal member includes a second discrete layer of thermoplastic resin and a second discrete layer of barrier material.

Closure system with barrier layer

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.

Multi-aperture spill-resistant spout

A container and method of manufacture of a container made of a single material is provided. The container includes a base having a base perimeter with a surface, and a wall having an upper edge and a lower edge, the upper edge comprising two upper edge portions, wherein the lower edge is affixed about the entire perimeter surface, and the first upper edge portion is affixed to the second upper edge portion, thereby forming a space to hold foodstuffs. The base stock material is cut and formed into a base with the base perimeter. A seal is applied between the lower edge of the wall and the surface of the base perimeter. Another seal is applied to two vertical end portions of the wall, forming a cup-like container with an internal space. A final seal is applied between two portions of the upper edge of the wall completing the container.
