Abstract: The rolled material dispenser of the present invention enables the user to securely grip the rolled material dispenser and safely cut rolled material installed within. The rolled material dispenser provides beveled corners allowing for better gripping and usage for users with decreased hand strength and dexterity. The user inserts the rolled material of their choice into the dispenser. The user opens the lid of the rolled material dispenser, pulls a desired length of material from the roll installed inside the dispenser device, and then closes the lid. Closing the lid secures the rolled material and positions the cutting device to sever the desired length of material. The cutting device travels along the track of the lid. The user slides the cutting device across the rolled material positioned underneath the lid to cut a portion of material from the roll installed within the dispenser.

The carton blank is formed into an open ended tube and a plurality of these tubes, in flattened condition, are stacked with the cutting teeth uppermost in which position they are coated, such as by a roller coating.

Abstract: A dispenser carton for dispensing sheet material, e.g., household wrap type sheet material. A unique structure at one corner of the carton permits tearing off a length of the sheet material after that length has been withdrawn from a roll inside the carton. The carton corner is comprised of plural serrated cutting sections each of which is cut through at least one of the panels, and plural fold sections which cooperate to connect the carton's walls together at that corner, the serrated and fold sections alternating along the corner's length from one end to the other. The serrated sections are of a length and number to permit tearing of the sheet material to desired length on that carton corner, and the fold sections are of a length and number to provide structural rigidity to the carton at that corner during normal use of the tearing edge and carton so formed.

Abstract: A dispenser carton for dispensing sheet material, e.g., household wrap type sheet material. A unique cutting edge structure for the carton permits tearing off a length of sheet material withdrawn from a supply roll inside the carton, while simultaneously braking the sheet material remaining on the roll during the tearing step to prevent inadvertent withdrawal of additional sheet material. In preferred form, the cutting edge structure is comprised of an abrasive applied to the free edge of the carton's closure flap, the abrasive being on the inside face of that closure flap. After the desired sheet material length is withdrawn from the roll within the carton, the carton's cover is closed and the closure flap is manually pressured against the carton's front wall. In this attitude, the abrasive and the closure flap's leading edge cooperate to provide a cutting edge by which the free length of sheet material can be torn off the supply roll from one edge to the other.

Abstract: A machine is disclosed which is intended to apply a saw-toothed blade to containers (for example of cardboard) which hold a coil or roller of aluminum foil or plastics material film of the kind used, for example in the kitchen or household in general. The saw-toothed blade must slightly protrude from the bottom front edge of the container to enable the user to tear out the portion of foil or plastics sheet to be used from time to time. The machine comprises a station in which the saw strips are severed from a metal tape and are applied to the flattened container, the latter being conveyed to the station by a conveyor belt assembly. The machine is equipped with appropriate cam and lever controlling and synchronizing means to have all the operative steps performed in the correct sequential order: the machine is compact and easily inspectable by one operator and the feeding means are all located on the longitudinal central axis of the machine.
