A stiffener apparatus, including first and second stiffener body sections, each section forming an open, geometric structure, with U-shaped channels facilitating mechanically mating the two sections, i.e. a quasi-congruent, multi-planar surface, snap-ring construction, that effects reliable compression of flexible material disposed between two mating sections. The stiffener sections are sized for fitting an opening of a flexible trash bag. An integral clamping mechanism securely latches the stiffener sections together and facilitates separating the sections. Mating channels compress the outer edges of the trash bag's opening material, greatly improving the compression fit keeping the trash bag open, especially in heavily loaded trash bag conditions. Each stiffener section, has a scooping ramp edge member for channeling material into the trash bag. One stiffener section has at least one handle with a notch for hanging the apparatus. The apparatus has means for attaching an optional hinged cover.

1. A stiffener apparatus comprising: clamping means having a first and a second stiffener section for securing a flexible sheet material when said flexible sheet material is disposed therebetween, said first stiffener section having latching means, said latching means being removably attachable to said second stiffener section, said latching means further including lever means for engaging and disengaging said latching means; and at least one handle provided on said second stiffener section for manipulating said stiffener apparatus, said at least one handle having at least one notch for hanging said stiffener apparatus, said notch disposed so that said stiffener apparatus hangs essentially level and vertical, said first stiffener section also including a plurality of slots, said slots being located adjacent opposite ends of said lever means to provide flexibility to said latching means for engaging and disengaging said latching means. 2. A stiffener apparatus as described in claim 1, wherein: said stiffening apparatus is geometrically shaped, having a substantially U-shaped cross section, and having a side member formed as a scooping ramp edge. 3. A stiffener apparatus as described in claim 1, further comprising: covering means attached to said first stiffener section. 4. A stiffener apparatus as described in claim 3, wherein: said stiffening apparatus is geometrically shaped, having a substantially U-shaped cross section, and having a side member formed as a scooping ramp edge. 5. A stiffener apparatus comprising: clamping means for securing a flexible sheet material when said flexible sheet material is disposed between a first and a second stiffener section, said first stiffener section having latching means, said latching means being removably attachable to said second stiffener section, said latching means further including lever means for engaging and disengaging said latching means, said first stiffener section having a plurality of slots adjacent opposite ends of said lever means to provide flexibility to said latching means for engaging and disengaging of said latching means; and covering means attached to said first stiffener section. 6. A stiffener apparatus as described in claim 5 further comprising: at least one handle provided on said second stiffener section for manipulating said stiffener apparatus, said at least one handle having at least one notch for hanging said stiffener apparatus, said notch disposed so that said stiffener apparatus hangs essentially level and vertical. 7. A stiffener apparatus as described in claim 6, wherein: said stiffening apparatus is geometrically shaped, having a substantially U-shaped cross section, and having a side member formed as a scooping ramp edge. 8. A method for stiffening an opening of a flexible bag comprising: a) separating a first stiffener section and a second stiffener section of a stiffener apparatus, said first stiffener section having latching means, said latching means further having lever means for engaging and disengaging said latching means, said first stiffener section having a plurality of slots adjacent opposite ends of said lever means, for facilitating engaging and disengaging said latching means whereby said separating is caused by lifting and rotating said lever from the slots and disengaging said lever from said latching means; b) placing said opening of said bag between said first and said second stiffener sections; c) clamping together said first and second stiffener sections, thereby stiffening said opening of said flexible bag; and d) removably latching said first stiffener section to said second stiffener section.
