Abstract
A reclosable attachment for containers for permitting the contents of the container to be discharged from the container includes a flange member, a cylindrical extension that extends from one side of the flange member, and a cylindrical stem that extends from the opposite side of the flange member. A cap is connected to the flange member and is adapted to be engaged and disengaged with the cylindrical extension in order to permit or prevent the discharge of the contents from the container. A feature is also provided on the reclosable attachment for preventing someone from unknowingly tampering with the container and for preventing the cap from being accidentally opened. Several spaced apart ledges which extend radially outwardly from the outer peripheral surface of the stem can also be provided for maintaining the position of the attachment relative to the container. Additionally, axially extending annular ridges can be formed on the side of the flange member that is adapted to be secured to the container for purposes of controlling the flow of the adhesive used to secure the attachment to the container.
