Patent

CA 2433342

A method is provided for manufacturing an antiperspirant product (10) that includes an application surface (16) having two portions (18, 20) having different compositions, e.g., a product having two sections having the same composition but separated by a third section (for instance, a central stripe) having a different composition. In one embodiment the method is for manufacturing an antiperspirant or deodorant product within a container (14) having an application end and an opposite end (15), the product having an application surface adjacent the application end. The method includes (a) delivering a first fluid composition through the opposite end (15) of the container (14) to a mold cavity that is defined at least in part by the container, the mold cavity including a removable insert (28); (b) allowing the first composition to at least partially solidify; (c) removing the insert (28) from the mold cavity to provide a space, and (d) delivering a second fluid composition to the space that was occupied by the insert.

L'invention concerne un procédé de fabrication d'un produit anti-transpiration (10) qui comprend une surface d'application (16) possédant deux parties (18, 20) ayant des compositions différentes, p.ex., un produit possédant deux parties ayant la même composition mais séparées par une troisième partie (par exemple, une bande centrale) ayant des compositions différentes. Dans un mode de réalisation de ce procédé, on fabrique un produit anti-transpiration ou déodorant à l'intérieur d'un récipient (14) comportant une extrémité d'application et une extrémité opposée (15), le produit possédant une surface d'application adjacente à l'extrémité d'application. Le procédé consiste en ce qui suit (a) acheminer une première composition à travers l'extrémité opposée (15) du récipient (14) vers une cavité de moule définie au moins en partie par le récipient, ladite cavité de moule comprenant une insert amovible (28); (b) permettre à la première composition de se solidifier au moins partiellement; (c) retirer l'insert amovible (28) à partir de la cavité de moule pour créer un vide; et (d) acheminer une deuxième composition fluide dans le vide préalablement occupé par l'insert.
