Background of the Invention
1. Field of the Invention
The present invention relates to a trash liner which is used in a trash container, the trash liner having tie strips which are used both to secure the top of the liner to the top of the trash container, and to tightly close the liner when it is full and ready to be removed from the container.
2. Description of the Prior Art
Plastic bags have been used for decades to dispose of trash in a sanitary manner, and to prevent trash containers from becoming soiled and contaminated by trash. They are used in a variety of applications, and come in different sizes and colors. There are specialized bags for carrying, covering, and containing all sorts of waste. Some may be tightly closed, but few can be secured to containers without premature collapsing. The present invention is the combination of a trash container with a bag, preferably made of plastic, for lining the trash container, having a single tie strip, also preferably made of plastic, passing through a single tubular channel at the top of the bag. The tie strip is used both to secure the top of the bag to the top of a trash container, and to tightly close the bag when it is full and ready to be removed from the trash container.

Detailed Description of the Preferred Embodiment
The present invention is a combination of a trash liner and a trash container, and a method of waste disposal using them. The trash container is preferably cylindrical or frustoconical, with a hollow interior and a circular top opening with a rim. The trash liner has tie strips which are used both to secure the top of the trash liner to the top of the container, and to tightly close the trash liner when it is full and ready to be removed from the container.
FIG. 1 is a right side perspective view of the preferred embodiment of the trash liner 10, showing the main body of the bag 12 and the opening of the bag 14. Along the greater part of the edge of the opening of the bag is a tubular channel 16. On one side of the opening there is an U-shaped notch 18. A tie strip 20 is inserted within the tubular channel. Opposite ends 22 and 24 of the tie strip extend from openings in the tubular channel at opposite sides of the U-shaped notch.
FIG. 2 is a front perspective view of the preferred embodiment of the trash liner 10. The width of the notch 18, between the two openings of the tubular channel 16, is preferably no greater than five, ten or twenty percent of the length of the edge of the opening 14 of the bag 12.
FIG. 3 is an front elevational view of the invention, showing the trash liner attached to the trash container A having a top opening with rim B. The edge of the opening 14 of the bag is placed outside the trash container's rim, while most of the bag's main body 12 is inside the container. When the liner is placed on the container, air inside the container is vented through the notch 18, so that the main body can lie flat against the interior surface of the container, and the container can be filled to its maximum capacity. (The portion of the liner that is inside the container is not shown in FIG. 3.) Opposite ends 22 and 24 of the tie band 20 are tied together to securely retain the liner on the container. When the container has been filled with trash or other contents, the contents can be securely removed from the container, by untying the ends of the tie strip, removing the edge of the opening of the bag from the rim of the trash container, closing the opening of the bag, and again tying the ends of the tying member to secure closure of the bag. The ends of the tie strip may then be used to lift the bag out of the container.
The bag should be made of a flexible material and should not have perforations, so that small particles may be retained within the bag. It is preferable that the material be impervious to water or other liquids that may be placed within the bag.
A cord or other flexible tying member may be substituted for the tie strip. The flexible tying member should be made of heavy gauge plastic or other material strong enough to support the weight of the bag. The tying member must be longer than the tubular channel, so that its ends will extend outside the channel's openings.
In the preferred embodiment both the bag and the tie strip are made of plastic. The plastic may be formed from polyethylene, vinyl-acetate copolymers, or other suitable polymers. The tie strip may be elastic, but it is preferable that it not be elastic, so that it will be easier to carry a filled bag by grasping the ends of the tie strip. The tubular channel may be formed by bending over the edge of the bag against its outside surface, and attaching the edge and outside surface by heat sealing or other suitable means.
Although primarily intended as a means and method of disposing of refuse, the invention may also be used for other purposes. It is to be understood that the present invention is not limited to the sole embodiment described above, but encompasses any and all embodiments within the scope of the following claims.
