Patent

CA 2355652

A closure (30) for a container is designed to facilitate the mixing of a first material within the container with a second material within the closure at the point of use. The first and second materials are generally chemically reactive. The plastics material closure (30) has a base (32) and a lid (34). The base (32), which is circular, has an annular peripheral rim (36) defining an annular recess (38) by which the closure (30) may be clipped onto a container (10). Radially inwardly of the rim (36) is an upstanding peripheral wall (40) defining a chamber (42) for containing the second material. A plunger (44) is affixed to the base (32) centrally of a convex button (50). When mixing of the first and second materials is required, the container (10) is positioned so that the base (32) of the closure is uppermost, and the button (50) is pressed to move the plunger (44) to push the lid (34) out of the opening of the chamber (42).

Selon l'invention, une fermeture (30) pour contenant est conçue pour faciliter le mélange d'une première matière et d'une seconde matière à l'intérieur de la fermeture, au point d'utilisation. La première et la seconde matières sont, en général, chimiquement réactives. La fermeture en plastique (30) comprend une base (32) et un couvercle (34). La base (32), qui est circulaire, présente un bord périphérique annulaire (36) délimitant un évidement annulaire (39) par lequel la fermeture (30) peut être ajustée par pression sur le contenant (10). Une paroi périphérique verticale (40), qui s'étend radialement vers l'intérieur du bord (36), délimite une chambre (42) destinée à contenir la seconde matière. Un poussoir (44) est fixé à la base (32), au centre d'un bouton convexe (50). Au moment de mélanger la première et la seconde matières, le contenant (10) est disposé de sorte que la base (32) de la fermeture se place à la position la plus élevée, et le bouton (50) est pressé pour déplacer le poussoir (44) et l'amener à pousser le couvercle (34) hors de l'ouverture de la chambre (42).
