A locking system for releasably holding open the opening of a plastic film bag, composed generally of a first locking element extending from the external surface of the plastic film bag adjacent the opening thereof and a second locking element extending from a shape defining structure. The first locking element lockably mates with the second locking element in a male-female fashion either by pressing them mutually together or by sliding one into the other. The shape defining structure may be a ring member of a sidewall of a trash receptacle or of a removable lid therefor, or some other structure, such as a free standing ring member which may or may not be of circular shape. The first and second locking elements may be configured in a number of different forms in order to accomplish the aforesaid mutual interlocking function. For example, a T-shaped tongue element extending from the exterior sidewall of the plastic film bag and a female groove having opposing bosses separated by a slot provided on the shape defining structure, wherein the T-shaped tongue element is slid into or out of the female groove in order to selectively hold open the plastic film bag. As another example, the first and second elements may be in the form of a bulbous male rib and female socket arrangement, wherein alignment guides may be optionally provided to assist aligning of the first and second elements.

A locking system for selectively holding open a bag, comprising: a substantially inflexible ring member formed in a shape of a substantially flat cylinder having a radially interior surface and a radially exterior surface, said radially interior surface defining a ring periphery; means for supporting said ring member; a bag having a predetermined flexibility, said bag having an exterior surface and an opening; a first locking element extending from said radially interior surface of said ring member; and a substantially flexible second locking element extending radially outward directly from said exterior surface of the bag adjacent said opening thereof; wherein said substantially flexible second locking element is pressed radially outward against said first locking element in order to mutually interlock said bag to said, substantially inflexible ring member; whereby said first locking element and said second locking element are each structured to releasably mutually interlock so that a user may selectively mutually interlock and mutually unlock said first and second locking members, wherein when said first and second locking members are mutually interlocked the exterior surface of said bag is disposed in substantial abutment with said ring member adjacent to an inner surface of said ring periphery until said first and second locking members are selectively mutually separated.
