Device for controlling the outward movement of the cutting blade of a drum in a wiping material dispenser

A dispensing apparatus comprising a casing with cover, said casing including arms supporting a reel of wiping material in an upper part, and including, in a lower part, a drum rotatably mounted between first and second flanges, said drum having a cutting blade fixed to a cutting blade holder which pivots relative to the drum during a cutting sequence, said reel bearing on said drum or being suspended above said first flange, said first flange having a first central ring, formed on an inner side of said first flange allowing for passage of a locking axis of said drum, said first ring having an external profile comprising a first fixed set of protuberances, a lever associated and pivoting with the cutting blade holder, and comprising a second set of protuberances, said external profile constitutes a guide path for said lever, interaction between said first and second sets of protuberances permits said outward pivotal movement of said cutting blade to perform said cutting sequence during rotation of said drum resulting from pulling of said wiping material by a user,

• wherein said first flange is provided with a second projecting ring and a third ring both fixedly formed on said inner side of said first flange facing said drum and being applied against a facing edge of said drum,
• wherein a lateral edge of an end flange of said drum has a projecting bar for pivotably receiving the cutting blade holder, said bar having a cutout for receiving a locking member formed on said lever,
• wherein said third ring interacts with said locking member at one stage of operating during the rotation of said drum, said third ring has a non-circular profile with an eccentric offset part, and said third ring has a rectilinear flat extending at an angle of the order of approximately 25° to 35° for pushing said locking member.
