ABSTRACT:
A dispersing closure is provided for an opening in an squeeze-type container and includes a body defining a dispensing passage for communicating between the container interior and the container exterior through a container opening. A flexible, self-sealing valve is provided with a peripheral flange, and the valve is mounted in the body for opening in response to increased container pressure. The body is of unitary construction and is molded from thermoplastic material with an upstanding peripheral wall that is subsequently deformed over the valve flange to retain the valve in the body. A preferred process for making the closure includes the steps of molding a unitary closure body with a seat for the valve flange surrounded by a peripheral wall, disposing the valve flange on the seat, and then deforming an upper portion of the wall into a generally annular configuration extending radially inwardly to overlie the seat and clamp the valve flange between the seat and the deformed portion of the wall.
