Abstract
A plastic container and closure and method of making the same. The container can include a solid bottom end, an outer sidewall extending from the solid bottom end, and a neck portion extending from the outer sidewall to create an open end of the container. The neck portion may have a spout portion having an aperture formed therein. The spout portion can be inverted to form a flange receptacle. The closure can include a sealing portion which includes a first receptacle, a spring portion that includes a second receptacle, and a planar center area configured in the center of the closure and extending inward from the spring portion. The container may be filled with a product and the closure secured to the container, over the open end, to create a primary seal and a secondary seal. When the closure is secured to the container, the spring portion can exert a sealing pressure against the neck portion of the container to create the primary seal.
