Description

  The present invention relates to a foldable garbage bag stand, and more particularly to a foldable garbage bag stand that can be folded and stored when not in use or transported.

  Generally, polyethylene or vinyl garbage bags are housed inside a garbage container in a plan view, circular or square shape, and the upper edge of the opening of the bag is folded back to the outside of the garbage container. In addition, it is inconvenient to move and transport, especially when it is large outdoors, and when the upper edge of the opening of the bag is not fixed, it will be blown off by strong winds and dust inside will be scattered around. There is.

Many proposals have been made to lock the garbage bags and the like on a stand. For example, there are No. 7-8308, No. 2-79215, No. 61-113702, and No. 7-8308 is inconvenient to store when not in use because it cannot be folded. Since the utility model 2-79215 uses a pair of left and right legs standing like a folding screen, it is not suitable for outdoor installation because it is easy to tip over with a little wind. Since Sho 61-113702 is used by inserting the upper peripheral edge of the garbage bag opened into the hooking protrusion provided on the upper edge, there is a risk of injuring the finger with the hooking protrusion when the garbage bag is attached or detached.
