    摘要： A dispenser for a coreless roll product having a pair of depressions defined in the ends of the coreless roll. The dispenser includes: a frame; mounting device for permitting the frame to be mounted to a stationary surface such as a wall; and a coreless roll securing device for securing a coreless roll product for rotation within the frame. The coreless roll securing device includes a pair of cooperating plungers. Each plunger includes: (1) a base, the base being fixed to the frame; (2) a distal end, the distal end having a radius of curvature; and (3) a central shaft, the central shaft connecting the base and the distal end and providing sufficient length so the plunger has a length at least as great as its widest dimension so the plunger is adapted to penetrate a depression defined at an end of a coreless roll product, so radial displacement of the coreless roll with respect to said frame is prevented during use. Also a method for installing a coreless roll of a product.

    摘要： An adapter for converting a core roll product dispenser into a dispenser for a coreless roll product having a pair of depressions defined in the ends of the coreless roll. The adapter includes: (1) a housing defining a central cavity and an opening at an end of the central cavity; (2) a retractable plunger having a distal end, a central shaft, and a base, the retractable plunger being configured so the base and a first portion of the central shaft is retained in the housing and the distal end and a second portion of the central shaft extend through the opening at an end of the central cavity so the plunger is adapted to penetrate a depression defined at an end of a coreless roll product; (3) a resilient element in communication with the plunger that can apply a force against the plunger so the plunger is adapted to retract into the central cavity when a greater opposing force is applied against its distal end during loading and extend when the greater opposing force is removed; and (4) an element that may be used to secure the adapter to a core roll product dispenser. The adapters may be part of a dispenser for a coreless roll product having a pair of depressions defined in the ends of the coreless roll.

    摘要： A system for dispensing coreless rolls of product. The system includes: (1) a rotary dispenser including a frame, a mounting mechanism and a pair of cooperating plungers, each plunger including: a base, the base being fixed to the frame; a distal end, the distal end having a radius of curvature; and a central shaft, the central shaft connecting the base and the distal end and providing sufficient length so the plunger has a length at least as great as its widest dimension so the plunger is adapted to penetrate a mounting hole defined at an end of a careless roll product, and (2) a coreless roll of product that is self-supporting in the rotary dispenser, the careless roll including: a rolled web of product that is wound substantially throughout its diameter about a winding axis into a cylinder having first and second flat ends; and at least one flat end defining a mounting hole at substantially the center of the winding axis of the coreless roll, the mounting hole having a depth and having sides generally perpendicular to the end of the roll, the sides being separated by a distance that is less than the depth of the hole. The mounting hole of the coreless roll is adapted to receive a plunger from a rotary dispenser such that radial displacement of the careless roll with respect to the frame is prevented during use.
