Claim 8

A cover member according to claim 3 wherein said detent member protrusions are formed as parallel transverse ribs.

Claim 9

Biological secimen processing container apparatus according to claim 1 wherein one of said detent members is formed as a tab extending from one edge of and generally coplanar with said top wall, there being a tongue depending from said tab and formed with a plurality of protrusions spaced therealong.

Claim 10

Biological specimen processing container apparatus according to claim 1 wherein said protrusions are formed as parallel ribs.

Claim 11

Bilogical specimen processing container apparatus according to claim 7 wherein said protrusions are formed as parallel ribs extending transversely across said tongue.

Claim 12

A biological specimen processing apparatus of adjustable size comprising in combination an open-topped, rectangular box-like base member having a perforated bottom wall and an open-bottomed rectangular box-like cover member having a perforated top wall, two opposing parallel longitudinal sidewalls and two opposing parallel transverse endwalls, wherein the open-topped rectangular box-like base member having a perforated bottom wall has two opposing parallel longitudinal sidewalls and two opposing parallel transverse endwalls extending upward from said bottom wall, said base member also having a slanted wall with an exterior surface capable of being easily written upon extending downwardly and outwardly from the upper surface of one of the transverse endwalls, the two longitudinal sidewalls extending beyond said transverse endwall to join said slanted wall to form a transverse chamber between said transverse endwall, said slanted wall and said extensions of said longitudinal sidewalls, said base member also having a transverse slot located along the junction between the slanted wall and the upper surface of the transverse endwall, said transverse slot providing upper access to said transverse chamber, said base member further having an outwardly projecting ridge along the outer surface of the other transverse endwall and communication with the upper surface of said endwall, and wherein the open-bottomed rectangular box-like cover member having a perforated top wall has first and second detent members formed at opposite ends thereof, said detent members being of generally L-shaped cross-section which project outwardly and thence downwardly from adjacent said top wall, said detent members each being formed with at least one protrusion thereon, the cover member of said apparatus being removably attached to said base member with the first detent member of said cover member being inserted through the transverse slot of said base member and with the second detent member of said cover member being placed over the outwardly projecting ridge of said base member, said cover member telescopically fitting within said base member, said cover member being supported in several positions with respect to said base member, in each of such positions an edge of the transverse slot of the base member is abutting a protrusion of the first detent member of the cover member and the projecting ridge of the base member is correspondingly abutting a protrusion of the second detent member of the cover member.

Claim 13

A biological specimen processing apparatus of adjustable size comprising in combination an open-topped, rectangular box-like base member having a perforated bottom wall and an open-bottomed rectangular box-like cover member having a perforated top wall, two opposing parallel longitudinal sidewalls and two opposing parallel transverse endwalls, wherein the open-topped rectangular box-like base member having a perforated bottom wall has two opposing parallel longitudinal sidewalls and two opposing parallel transverse endwalls extending upward from said bottom wall, said base member also having a slanted wall with an exterior surface capable of being easily written upon extending downwardly and outwardly from the upper surface of one of the transverse endwalls, the two longitudinal sidewalls extending beyond said transverse endwall to join said slanted wall to form a transverse chamber between said transverse endwall, said slanted wall and said extensions of said longitudinal sidewalls, said base member also having a transverse slot located along the junction between the slanted wall and the upper surface of the transverse endwall, said transverse slot providing upper access to said transverse chamber, said base member further having an outwardly projecting ridge along the outer surface of the other transverse endwall and communication with the upper surface of said endwall, and wherein the open-bottomed rectangular box-like cover member having a perforated top wall has first and second detent members formed at opposite ends thereof, said detent members being of generally L-shaped cross-section which project outwardly and thence downwardly from adjacent said top wall, said detent members each being formed with at least one protrusion thereon, the cover member of said apparatus being removably attached to said base member with the first detent member of said cover member being inserted through the transverse slot of said base member and with the second detent member of said cover member being placed over the outwardly projecting ridge of said base member, said cover member telescopically fitting within said base member, said cover member being supported in several positions with respect to said base member, in each of such positions an edge of the transverse slot of the base member is abutting a protrusion of the first detent member of the cover member and the projecting ridge of the base member is correspondingly abutting a protrusion of the second detent member of the cover member.
