A bag opener is presented as an accessory component for bag roll dispensers, which is suitable for multiple-ply bags (such as star sealed bags) that are dispensed from a continuous roll and allows bags to be dispensed to the user in a partially opened state.

Bag holder apparatus including a bag support platform, a rigid, upstanding back structure and a bag retainer structure fixedly attached to the back structure, the retainer structure including an elongated bar elevated relative to an upper end of the back structure and downwardly extending elongated bag engagement members spaced from the back structure.

A cassette for dispensing bags from an elongated tubing comprising an annular receptacle accommodating a length of tubing in an accumulated condition. An annular opening at an upper end of the annular receptacle is for dispensing the tubing. The annular receptacle defines a central opening through which a knotted end of the tubing passes to form a bag supported by the annular receptacle with disposable objects passing through the circular central opening to be received in the bag, and a clearance only at a bottom of the central opening.

The present disclosure relates, in general, to a bag retaining device for use with bags that hang on bars in order to keep them orderly, clean, and to help control the bag flow for the user. These bag retaining devices apply to all bags that hang on bars by using the bag's mounting holes and have a focus on bags that are very long and wide with folds that allow the bag to become smaller for storing the bag on bars until use. The bags can be very heavy and thick and be difficult to work with. This invention will allow bags that are used for trash to stay elevated and not make contact with dirty floors or surfaces while hanging on the bars, until the user is ready. The user will be able to load these large bags onto the bars and secure the bags until ready for use.
