Test tube support

Claim 2

A foldable test tube support formed from rectangular sheet material, said test tube support having a compartmentalized top, a bottom, a front wall, a doubled rear wall and a compartmentalized intermediate wall interposed between the top and the bottom, said sheet material having in series: a large front wall section adapted to form said front wall and having a plurality of windows: a narrow top section adapted to form said top and having a plurality of openings, the top section being separated from the front wall section by a first fold line; an outer rear wall section having the same size as the front wall section, the outer rear wall section being separated from the top section by a second fold line; a bottom section adapted to form said bottom and having the same size as the top section, the bottom section being separated from the outer rear wall section by a third fold line; a first wall section adapted to be bonded to said front wall section to secure the same, said first wall section being so narrow that said intermediate wall is located near but spaced from said bottom when the test tube support is formed, said first wall section being separated from the bottom section by a fourth fold line; an intermediate wall section adapted to form said intermediate wall, and having a plurality of openings corresponding in number and location to the openings of said top and the same size as the top section, the intermediate wall section being separated from the first wall section by a fifth fold line; and an inner rear wall section adapted to be bonded to said outer rear wall section, forming therewith said doubled rear wall when the test tube support is formed, the total size of the inner rear wall section and the first narrow wall section having substantially the same size as the front wall section, the inner rear wall section being separated from the intermediate wall section by a sixth fold line; said outer rear wall section has substantially at a center area thereof a rectangular first support wall section having a slit therein defined by a seventh fold line parallel to and adjacent to said second fold line, a first cut line provided in said third fold line and opposed second and third cut lines, and said inner rear wall section has substantially at a center area thereof a rectangular second support wall section defined by eighth fold line parallel to and adjacent to said sixth fold line, a fourth cut line opposite said eighth fold line and opposed fifth and sixth cut lines, said second support wall section being adapted to be lockingly fitted into said slit in said first support wall section to support the test tube support when it is constructed.

Claim 3

A foldable test tube support formed from a rectangular sheet material, said support having a compartmentalized top, a bottom, a front wall, a doubled rear wall and a comparTmentalized intermediate wall interposed between the top and the bottom, said sheet material having in series: a large front wall section adapted to form said front wall and having a plurality of windows; a narrow bottom section adapted to form said bottom, the bottom section being separated from the front wall section by a first fold line; an outer rear wall section having the same size as the front wall section, the outer rear wall section being separated from the bottom section by a second fold line; a top section adapted to form said top and having a plurality of openings and the same size as the bottom section, the top section being separated from the outer rear wall section by a third fold line; a first wall section adapted to be bonded to said front wall section to secure the same, said first wall section being so narrow that said intermediate wall is located near but spaced from said top when the test tube support is formed, said first wall section being separated from the top section by a fourth fold line; an intermediate wall section adapted to form said intermediate wall, and having a plurality of openings corresponding in number and location to the openings of said top section and the same size as the top section, the intermediate wall section being separated from the first wall section by a fifth fold line; and an inner rear wall section adapted to be bonded to said outer rear wall section, forming therewith said doubled rear wall when the test tube support is formed, the total size of the inner rear wall section and the first wall section having substantially the same size as the front wall section, the inner rear wall section being separated from the intermediate wall section by a sixth fold line; said outer rear wall section has substantially at a center area thereof a rectangular first support wall section having a slit therein defined by a seventh fold line parallel to and adjacent to said third fold line, a first cut line provided in said second fold line and opposed second and third cut lines, and said inner rear wall section has substantially at a center area thereof a rectangular second support wall section defined by an eighth fold line parallel to and spaced from said sixth fold line, a fourth cut line opposite said eighth fold line and near said sixth fold line, and opposed fifth and sixth cut lines, said second support wall section being adapted to be lockingly fitted into said slit in said first support wall section to support the test tube support when it is constructed.

Claim 4

A foldable test tube support formed from a rectangular sheet material, said support having a compartmentalized top, a bottom, a front wall, a doubled rear wall and a comparTmentalized intermediate wall interposed between the top and the bottom, said sheet material having in series: a large front wall section adapted to form said front wall and having a plurality of windows; a narrow bottom section adapted to form said bottom, the bottom section being separated from the front wall section by a first fold line; an outer rear wall section having the same size as the front wall section, the outer rear wall section being separated from the bottom section by a second fold line; a top section adapted to form said top and having a plurality of openings and the same size as the bottom section, the top section being separated from the outer rear wall section by a third fold line; a first wall section adapted to be bonded to said front wall section to secure the same, said first wall section being so narrow that said intermediate wall is located near but spaced from said top when the test tube support is formed, said first wall section being separated from the top section by a fourth fold line; an intermediate wall section adapted to form said intermediate wall, and having a plurality of openings corresponding in number and location to the openings of said top section and the same size as the top section, the intermediate wall section being separated from the first wall section by a fifth fold line; and an inner rear wall section adapted to be bonded to said outer rear wall section, forming therewith said doubled rear wall when the test tube support is formed, the total size of the inner rear wall section and the first wall section having substantially the same size as the front wall section, the inner rear wall section being separated from the intermediate wall section by a sixth fold line; said outer rear wall section has substantially at a center area thereof a rectangular first support wall section having a slit therein defined by a seventh fold line parallel to and adjacent to said third fold line, a first cut line provided in said second fold line and opposed second and third cut lines, and said inner rear wall section has substantially at a center area thereof a rectangular second support wall section defined by an eighth fold line parallel to and spaced from said sixth fold line, a fourth cut line opposite said eighth fold line and near said sixth fold line, and opposed fifth and sixth cut lines, said second support wall section being adapted to be lockingly fitted into said slit in said first support wall section to support the test tube support when it is constructed.
