CA 2223249

A cap (12) and tube (16) assembly comprising a tube (16) for containing a product and a cap (12) for closing an opening in the tube. The tube (16) has a nozzle (18) at one end with a diaphragm (28) puncturable to provide a discharge opening for dispensing of products. The cap (12) is engageable over the nozzle and has a means for puncturing (32) depending inwardly from the top of the cap and operable upon actuation of the cap (12) relative to the nozzle (18) to puncture the diaphragm (28). Ribs (50) on the interior of the cap snugly embrace the nozzle (18) during axial movement of the cap to ensure alignment of the piercing element (32) with the diaphragm (28) during the piercing operation.

Ensemble constitué par un bouchon (12) et par un tube (16), ledit tube (16) étant conçu pour contenir un produit et ledit bouchon (12) étant conçu pour fermer une ouverture dans le tube. Une extrémité du tube (16) possède un ajutage (18) comportant une membrane (28) pouvant être perforée, afin de créer une ouverture d'évacuation servant à distribuer les produits. Le bouchon (12) peut se placer au-dessus de l'ajutage et possède un moyen de perforation (32) s'étendant vers l'intérieur depuis le sommet du bouchon et servant à perforer la membrane (28), lorsqu'on actionne le bouchon (12) par rapport à l'ajutage (18). Des nervures (50) situées sur l'intérieur du bouchon enserrent l'ajutage (18) pendant le déplacement axial du bouchon, de manière à assurer l'alignement de l'élément de perforation (32) sur la membrane (28) pendant la perforation.
