Abstract: This portable device is for holding and supporting a flexible waste collection bag in an open condition. The device has a frame consisting of two parallel side bars having a handle at one end and the free ends of the side bars are mounted to a lower supporting platform bar. A slider bar is slidably mounted on the side bars and located between the handle and the lower supporting platform bar. Both the slider bar and the supporting platform bar have a horizontal U-shaped channel. A flexible waste collection bag can be mounted to the device by wrapping two opposite sides of the lip portion of the bag on two securement bars and inserting the wrapped securement bars into the U-shaped channels in the slider bar and the supporting platform bar to secure the bag to the device. The slider is pushed upwards to maintain the bag in an open condition. Bags of a variety of different sizes may be mounted to the device by adjusting the position of the slider bar.
