Shipping container for rodents

A container for shipping medically useful rodents, said container comprising:

• a base having a boxlike shape defined by connecting side and end walls, a peripheral edge flange joining to upper ends of said walls with said edge flange having a horizontal leg connecting with a vertical leg having a set of spaced apart notches, and a set of openings formed in said walls,
• a lid formed with a set of openings and an edge channel defined by an inner rib and an outer flange formed with offset snaps spaced to align with said base edge flange notches and a pair of sealing beads on a top wall of said channel, said channel fitting snugly over said base edge flange and said sealing beads being in continuous contact with said base edge flange horizontal leg so that said lid edge channel forms an airtight fit with said base edge flange, and
• filter units disposed in said base and lid openings, said units defined in part by a support member having a raised edge with an outward facing channel having an inner rib spaced from an outer flange and a sealing bead on said outer flange so that said filter unit raised edges form air tight fits with edges of said base and lid openings,
• wherein movement of air into and out of said container is restricted to that through said filter units.

A rodent shipping container comprising:

• a base, said base having a bottom wall connecting with outwardly sloped sides and end walls, a peripheral edge flange joining upper ends of said side and end walls, a set of spaced apart notches formed in a vertical leg of said edge flange, and a set of openings in said side and end walls,
• a lateral partition, said partition located in an interior space of said base to divide said space into large compartments, said partition having spaced apart perforated end portions connection by a feeding bin with outer edges of said partition end portions releasably held by ribs on an inner side of each said base sidewall and said bottom wall,
• a lid, said lid having a middle cross piece having respective ends formed edge channels, said channel having an inner rib and an outer flange with an offset snap on a bottom end of said outer flange selectively secured in said aligning notches in said base edge flange to hold said cross piece to said base and form a sealed fit therewith, spaced apart outer sections integrally hinged to said cross piece with each outer section having a raised portion defined in part by top horizontal segment connecting spaced apart, sloped end walls and an edge channel to mate with said base edge flange, said outer section edge channels each having an inner rib and an outer flange with a set of spaced offset snaps on a bottom end of an outer flange to engage said respective aligning notches in said base edge flange to hold said lid outer sections to said base and form sealed fits therewith, a set of openings in said each said raised portion end walls, and ribs on an inner side of said lid cross piece to engage upper ends of sidewalls of said lateral partition feeding bin, and
• a filter unit releasably disposed one each in said base and lid openings, said filter unit including a support member having a raised edge fitting about a perforated backing plate with said raised edge having an outward facing channel defined by an outer flange and an inner rib fitting about an edge of said opening and forming sealed fit therewith and sets of spaced apart holding tabs on an inside of said raised edge positioned to align with slots in said backing plate, and a retainer having a perimeter edge segment fitting about an open structure, said retainer prepared to hold a piece of filter cloth on said support member backing plate with said retainer perimeter edge segment fitting under said support member raised edge holding tabs,
• wherein after completion of a shipment of said rodents, said lid may be disassembled from said base, said lateral partition removed from said base, said filter units removed from said lid and base and then disassembled to allow a thorough cleaning of said lid, base and filter unit components to inhibit cross-contamination of rodents in a next shipment.
