说明书全文 | This is a continuation of Ser. No. 10/393,552, filed on Mar. 21, 2003 now U.S. Pat. No. 7,073,676, which is a continuation of Ser. No. 09/930,408, filed on Aug. 15, 2001 now abandoned, to which this application claims priority and which are hereby incorporated by reference in its entirety. This invention relates to containment bags used with large dumpster style disposal containers in the storage, transportation and disposal of wastes. In plant renovations or other type of construction or clean-up projects, wastes are generated and stored in large on-site dumpster—containers, such as rolloff containers, end dump containers, and gondola rail car containers. When hazardous materials (such as tank cleaning sludge, wet or dry waste materials, chemical plant by-products, rail wastes, high heat wastes), odorous materials, or fine particulate matter (for instance, incinerator ashes, powders, asbestos materials) are to be stored in an onsite dumpster container for later transportation and disposal, it is desirable to line the container to protect the container from exposure to the materials and to make later disposal easier. Currently, either large sheets of plastic are used to line the container or container bags are utilized. The existing container bags have openings that are closable using a series of ties or cords. Given the large size of the containers, closing the series of ties can be a time consuming chore. Further, the ties fail to make an effective seal. The invention consists of non-self supporting containment bag used in conjunction with a dumpster container. The bag has a zipper or other sealable means and a series of pick-up or attachment loops or handles may also be attached to the outer bag material. The bag may additionally have an internal lining. It is an object of the invention to provide a simple easily installable liner for a dumpster container that is sealable. It is another object to provide a liner for use in a dumpster container having attachment or pick-up handles. It is another object of the invention to provide a containment bag for use in a dumpster container having a secondary liner on the interior of the containment bag. Three existing dumpster type containers are shown in Shown in The bag should have an opening 2 that is sealingly closable. Bag opening 2 should be placed on the bag for ease of loading and storage of materials and, in some instances, for ease of removal of the stored materials. For instance, the bag shown in Also shown are support handles 5 in Additionally, the bag 1 may incorporate a separate inner liner 10 (not shown). Inner liners are useful when the stored materials are wet or liquids. Suitable material can be low-density polyethylene, with 6-10 mil thickness being preferred. One such liner is disclosed in U.S. Pat. No. 5,110,005, herein incorporated by reference. Inner liner may be sewn to the outer bag, or attached by other means, for instance heat-sealed to the outer bag. The container bag as shown is intended to be disposed with the stored wastes, and not intended to for re-use. Shown in It is intended that the following claims be interpreted as covering all such alterations and modifications as fall within the true spirit and scope of the invention. |
