  • Publication number: 20220233034
    Abstract: The present disclosure relates to a continuous toilet seat cover sheet reel, an automatic toilet seat cover dispenser, and methods of using the automatic toilet seat cover dispenser. In certain embodiments, the automatic toilet seat cover dispenser includes: a dispenser sensing system for detecting a user's demand of a toilet seat cover sheet, a dispenser control system for moving one toilet seat cover sheet out at a time from a continuous toilet seat cover sheet reel, and a toilet seat cover dispensing system for delivering the toilet seat cover sheet to the user. When the user is in need of a toilet seat cover sheet, the user activates the dispenser sensing system, the dispenser control system moves one toilet seat cover sheet out at a time from the continuous toilet seat cover sheet reel, and the toilet seat cover dispensing system delivers the toilet seat cover sheet to the user.

  • Publication number: 20220125250
    Abstract: The present disclosure relates to continuous toilet seat cover reel having a predetermined number of toilet seat cover sheets. Each toilet seat cover sheet includes a seat cover portion and a splash prevention tongue. Seat cover portion includes a sheet separation marking line printed between two adjacent toilet seat cover sheets to indicate where toilet seat cover sheet is cut from the continuous toilet seat cover reel. Printed sheet separation marking line between two adjacent toilet seat cover sheets guides a user to cut the toilet seat cover sheet from the continuous toilet seat cover reel. Splash prevention tongue includes a predetermined number of attached segments and a predetermined number of detached segments along its outer edge to allow a user to separate partially the splash prevention tongue from the seat cover portion and allow the splash prevention tongue to hang into a toilet to prevent splash.

  • Publication number: 20210197515
    Abstract: The present disclosure relates to methods of using a machine for manufacturing continuous toilet seat cover reels. Methods include: loading a continuous paper roll onto a shaft in a first end of the machine; threading continuous paper on continuous paper roll through a continuous paper reel transmission mechanism, a printing wheel, a modular cutting mechanism, a counting wheel of the machine, onto a reel at a continuous toilet seat cover reel output device in a second end; perforating continuous paper roll to form sheet perforated tear lines, a splash prevention perforated tear line, one or more vertical splash prevention perforated tear lines and horizontal splash prevention perforated tear lines; counting the number of toilet seat cover sheets generated on the continuous toilet seat cover; and cutting the last sheet of toilet seat cover sheet from the continuous toilet seat cover to produce the continuous toilet seat cover reel.

  • Publication number: 20210197514
    Abstract: The present disclosure relates a machine for manufacturing continuous toilet seat cover reels. In certain embodiments, the machine includes: a continuous paper reel transmission mechanism, a modular cutting mechanism, and a counting wheel. The continuous paper reel transmission mechanism receives continuous paper from a continuous paper reel on a continuous paper reel rotating shaft. The modular cutting mechanism with a modular cutting wheel receives continuous paper reel from the continuous paper reel transmission mechanism and perforates the continuous paper reel using the modular cutting wheel to generate a continuous toilet seat cover. The counting wheel counts the number of toilet seat cover sheets on the continuous toilet seat cover generated. When the number of toilet seat cover sheets generated reaches a predetermined number, continuous toilet seat cover reel output device cuts last toilet seat cover sheet from the continuous toilet seat cover to produce the continuous toilet seat cover reel.
