An apparatus and method for securely holding a trash or garbage bag is provided. Said device comprises a base support frame, a rectangular shaped frame, and rotatable connecting means for connecting the two. The method comprises inserting the frame into the open end of a trash bag and rotating the rectangular shaped frame so as to securely hold the trash bag.

A bag holder for use with a flexible bag is disclosed. The bag holder has a lower support member, an upper support and a plurality of resiliently flexible struts. The top end portion of each strut is connected to the upper support member and is pivotal in a plane tangential to the upper support member. The bottom end portion of each strut is connected to the lower support member and is pivotal in a plane tangential to the lower support member. The bag holder has an operative position where the upper support member is vertically spaced from the lower support member and a stored position where the lower support member, the upper support member and the plurality of struts are generally in the same plane. The bag holder is moved from the operative position to the stored position by twisting the upper support member relative to the lower support member and pushing the upper support member into generally the same plane as the lower support member. The bag holder also includes a kit or disassembled form.

A hinge assembly enables the setting of elements attached to the hinge assembly to any angle within the range of motion of the hinge assembly without the use of other mechanisms or parts.

A bag holder for suspending a bag thereat with an opening portion of the bag directed upward, comprising a pair of arm members respectively provided with holding members for engaging and holding an opening edge portion of the bag, a pair of crossing means that intersect with each other being extended downward from end portions of the arm members and making the pair of arm members freely open/close around a fulcrum portion, and a pair of grounding members being extended from lower ends of the pair of crossing members as to oppose the pair of arm members. Attaching/detaching of the bag can be easily performed since the bag might simply be hung against or detached from a pair of holding means. Further, since bags can be held in a suspend manner, the external appearance thereof can be made attractive and cleaning of the floor can be easily performed.
