A tamper evident flip top pouring closure is designed for use with a corresponding container. A tamper evident flip top pouring closure and container in combination has a closure with a screw thread thereon together with interlocking means and a container with the corresponding screw thread and corresponding interlocking means. The interlocking means prevents the removal of the closure from the container once the closure is installed on the container. The interlocking means on the closure are a series of tabs that are connected to the closure and extend inward at an angle. The interlocking means on the closure are two sets of saw-teeth having a gentle slope on one side and a steep slope on another side. The closure is then installed on the container and cannot be removed because the tabs abutt a steep slope of the saw-teeth and will not override the saw-teeth in a reverse direction.

Bouchon verseur inviolable à charnière, associé à un contenant pour lequel il est conçu. Cet ensemble est constitué des éléments suivants : un bouchon avec filetage et dispositif de verrouillage, et un contenant dont le filetage et le dispositif de verrouillage correspondent à ceux du bouchon. Le dispositif de verrouillage, destiné à prévenir le retrait du bouchon une fois celui-ci installé sur le contenant, est constitué d'une série de languettes reliées au bouchon et se prolongeant angulairement vers l'intérieur, ce dispositif de verrouillage du bouchon étant formé de deux séries de dents de scie, à faible pente d'un côté et à forte pente de l'autre. Le bouchon, lorsqu'il est mis en place, ne peut être retiré du contenant, car les languettes, qui s'appuient sur une forte pente des dents de scie, ne peuvent recouvrir les dents de scie de l'autre côté.
