Test tube holder

Claim 2

A test tube holder comprising, a U-shaped base member fabricated of a molded polymeric material and having a horizontal bottom wall and a pair of upstanding sidewalls formed integrally of said bottom wall, a multileveled, C-shaped tube-retaining support member fabricated of a molded polymeric material and having one vertical wall and a pair of horizontal walls, a plurality of axially aligned apertures in said support member horizontal walls, track means recessed within said sidewalls of said base member and serving to slidably support the lower horizontal wall of said support member, and means associated with said base member sidewalls and operatively associated with both said bottom wall and said vertical wall to releasably retain said support member in a desired assembled relationship with said base member.

Claim 3

The invention as set forth in claim 1 wherein said base member is color coded.

Claim 4

The invention as set forth in claim 1 wherein a portion of said apertures in both levels are circular in shape, axially aligned and extend vertically through both levels of said multileveled tube retaining support member, and a portion of said apertures are circular in shape and extend vertically through only one level of said multileveled tube-retaining support member.

Claim 5

The invention as set forth in claim 3 wherein the portion of said apertures which extend vertically through only one level of said multileveled tube-retaining support member are of a larger diameter than the portion of said apertures extending vertically through both levels of said multileveled tube-retaining support member.

Claim 6

The invention as set forth in claim 3 wherein yet another portion of said apertures extend angularly through one level of said multileveled tube-retaining support member.

Claim 7

The invention as set forth in claim 1 wherein said multileveled tube-retaininG support member is stepped and includes in addition to said apertures a plurality of slots in the bottom level of said support member which extend inwardly from one longitudinal edge thereof adjacent said angularly extending apertures.

Claim 8

The invention as set forth in claim 1, wherein said upwardly displaceable wall is a reciprocably displaceable gate member which fits into sliding engagement within a pair of protrusions.

Claim 9

The invention as set forth in claim 2 wherein a ledge is circumferentially disposed about the outer edge of said upstanding walls and oriented to receive said cover member.

Claim 10

The invention as set forth in claim 2 wherein said track means comprises a pair of grooves disposed longitudinally of the upstanding sidewalls.

Claim 11

A test tube holder comprising, a U-shaped base member having a horizontal bottom wall and a pair of upstanding sidewalls affixed to said bottom wall, wherein at least one of said walls displaces upwardly allowing the egress of a multileveled tube-retaining support member, a multileveled, C-shaped tube-retaining support member having one vertical wall and a pair of horizontal walls, a plurality of axially aligned apertures in said support member horizontal walls, track means in said base member sidewalls, slidably supporting at least one of said support member horizontal walls, means associated with said base member sidewalls to releasably retain said support member in a desired assembled relationship with said base member, and a cover member disposed atop the upstanding sidewalls of said base member to cover the tubes contained in said support member.

Claim 12

A test tube holder comprising, a U-shaped base member having a horizontal bottom wall and a pair of upstanding sidewalls affixed to said bottom wall, wherein at least one of said walls displaces upwardly allowing the egress of a multileveled tube-retaining support member, a multileveled, C-shaped tube-retaining support member having one vertical wall and a pair of horizontal walls, a plurality of axially aligned apertures in said support member horizontal walls, track means in said base member sidewalls, slidably supporting at least one of said support member horizontal walls, means associated with said base member sidewalls to releasably retain said support member in a desired assembled relationship with said base member, and a cover member disposed atop the upstanding sidewalls of said base member to cover the tubes contained in said support member.
