Impervious Bag With Pervious Portion Patents (Class 55/364)
  • Patent number: 10301726
    Abstract: The present invention provides a gas generator and comprises an electrolytic cell, a condensate filter device, and an atomizing device. The electrolytic cell is for electrolyzing electrolyzed water to generate a gas with hydrogen. The condensate filter device includes a gas pathway, a filter, and an isolated component. The isolated component is used for limiting the movement of the filter inside the gas pathway. The gas generated from the electrolytic cell is condensed and filtered through the filter for generating a filtered gas with hydrogen. The atomizing device is used for generating an atomizing gas to be mixed with the filtered gas to generate a healthy gas. The present invention uses the condensate filter device to filter out the electrolyte from the filtered gas with hydrogen to be mixed with the atomizing gas for generating the healthy gas.

  • Patent number: 8266763
    Abstract: A leaf and lawn vacuum bagger has a housing that is attached to the exhaust outlet of a conventional leaf and lawn blower/vacuum or mulching device, and an air permeable bag releasably connected to the exhaust outlet has a fastener closure at a bottom end. A flexible sleeve is secured at one end to the housing and the air permeable bag is releasably connected at the opposed end for capturing the vacuumed yard debris. A closure member attached to the housing is selectively closed to allow exhaust gases from the lawn blower/vacuum or mulcher device to exit through the pores of the air permeable bag to the atmosphere, and leaves and yard debris exhausted through the blower/vacuum or mulcher falls down through the interior of said air permeable bag, through said sleeve, and are collected in the housing interior, and when opened, the collected leaves and yard debris falls through the housing and into the attached disposable bag, and the attached bag is then removed and replaced as needed.

  • Patent number: 6988293
    Abstract: A leaf collection system for lawn blower/vacuums is disclosed. The collection system includes a port coupling fitted to the exhaust port of a blower/vacuum, a dust cover, and a unique disposable collection bag. The disposable collection bag is constructed of an environmentally friendly, bio-degradeable plastic that will quickly decompose along with the organic leaves and lawn debris collected therein. Both sides of the collection bag has several rows of T-shaped slits and two rows of straight or I-shaped slits that allow air to escape from the bag but retain the leaves and lawn debris deposited therein. The collection bag is shaped to fit inside the dust cover that is fixed to the port coupling. The port coupling includes an elastic lock ring that secures the collection bag to the coupling. The dust cover envelops of the collection bag and shields the operator from the dust that passes through the collection bag.

  • Patent number: 3995414
    Abstract: A removable trash bag assembly for lawn mowers, wherein the bag is made of plastic and is hung from a frame attached to the mower. The bag is provided with hanging loops for easy mounting and removal with respect to the frame; and the mounting is arranged to flex the bag in tension to open slits provided in the side of the bag at its mouth due to the increasing weight of the trash as the bag progressively gets filled to exhaust the air when the primary vents in the mid-portion of the plastic are blocked. These slits also function to prevent bursting of a closed filled bag when it is dropped by providing vents at the top of the bag for any entrapped air. These slits are also functional to pass the folded open end portion of the bag therethrough to close the bag.
