A coinjection molded multi-layer container comprising: an inner layer comprising a first polymeric material and forming an inside surface of the container; an outer layer comprising the first polymeric material and forming an outside surface of the container; a barrier layer located between the inner layer and the outer layer and comprising a second polymeric material less permeable to gas than the first polymeric material, wherein the barrier layer is biased toward the inside surface or the outside surface such that the inner layer and the outer layer have different thicknesses; wherein the inner layer , the barrier layer , and the outer layer form a multi-layer wall structure defining a base of the container and a side wall of the container, the side wall of the container having a lower rim coupling the side wall of the container to a perimeter of the base of the container; an energy director ring protruding from the inside surface and extending circumferentially along the inside surface , the energy director ring configured to concentrate a welding force applied to the inside surface ; a filter comprising a base of the filter and a side wall of the filter, the side wall of the filter welded to the inside surface at a location of the energy director ring such that a gap exists between the base of the filter and the base of the container, the gap allowing the base of the container to be punctured when the container is in use without puncturing the filter ; and a circumferential weld formed along the inside surface at the location of the energy director ring as a result of welding the filter to the inside surface , the weld securing the filter to the inside surface . an inner layer comprising a first polymeric material and forming an inside surface of the container; an outer layer comprising the first polymeric material and forming an outside surface of the container; a barrier layer located between the inner layer and the outer layer and comprising a second polymeric material less permeable to gas than the first polymeric material, wherein the barrier layer is biased toward the inside surface or the outside surface such that the inner layer and the outer layer have different thicknesses; wherein the inner layer , the barrier layer , and the outer layer form a multi-layer wall structure defining a base of the container and a side wall of the container, the side wall of the container having a lower rim coupling the side wall of the container to a perimeter of the base of the container; an energy director ring protruding from the inside surface and extending circumferentially along the inside surface , the energy director ring configured to concentrate a welding force applied to the inside surface ; a filter comprising a base of the filter and a side wall of the filter, the side wall of the filter welded to the inside surface at a location of the energy director ring such that a gap exists between the base of the filter and the base of the container, the gap allowing the base of the container to be punctured when the container is in use without puncturing the filter ; and a circumferential weld formed along the inside surface at the location of the energy director ring as a result of welding the filter to the inside surface , the weld securing the filter to the inside surface . <EOS>
