Abstract
A container and closure package for dispensing a fluent product that includes an integrally molded plastic container and a one-piece molded plastic closure. The closure is secured to the container within a recess in the upper portion of the container so that the closure conforms to the outlines of the container body. The closure has a base with an annular wall and an interior bead that is received by snap fit over an exterior bead on an annular wall surrounding the outlet opening of the container. A pair of laterally opposed aprons depend from the closure base, and have interior beads that are received by snap fit over exterior beads on the container for enhanced retention of the closure on the container. Strengthening webs extend along the recessed portion of the container to the annular wall surrounding the container outlet opening to strengthen the container against buckling during application of the closure. Gussets extend from the closure aprons to the annular wall of the closure base for rigidifying the closure base.
