2 Claims, 4 Drawing Figures WHHHHHWITW TEST TUBE SUPPORT This invention relates to a test tube support for use in storing or transporting glass tubes such as test tubes etc.

Conventionally, a test tube support has been manufactured from wood. Such test tube support is rigid in construction and durable. However, it is expensive and difficult to manufacture. Moreover, it is very inconvenient for storage or transportation.

It is accordingly an object of this invention to provide a test tube support formed by folding a sheet-like material such as a cardboard etc.

Another object of this invention is to provide a simple and inexpensive test tube support which is easy to manufacture and very convenient for storage or transportation.

The above-mentioned objects, as well as other objects, can be attained by a test tubesupport formed by folding a sheet-like material, such as a cardboard, bearing' a particular pattern.

The sheet-like material has a first section having a plurality of windows and constituting a relatively wide front wall; a second section having a plurality of openings and constituting a narrow upper compartmentalized wall, a third section having a corresponding number of openings aligned with said plurality of openings of said second section and constituting a lower compartmentalized wall; a fourth section having a first support wall with a slit and constituting the outer wall of a relatively wide rear panel; a fifth section having a second support wall with a projection and constituting the inner wall of the relatively wide rear panel; a sixth section constituting a narrow bottom; and a seventh section constituting a narrow wall. The first, second, third, fourth, fifth, sixth and seventh sections are defined by, and being foldable along, folding lines. The test tube support is formed by folding the sheet-like material along these folding lines, bonding said fifth section and said seventh section to said fourth section and the rear surface of said first section, respectively, and lockingly fitting the projection of said second support of said fifth section into the slit of said first support wall of said fourth section.

This invention will be further described by reference to the accompanying drawings, in which:

FIG. 1 is a plan view showing a sheet-like material from which a test tube support according to this invention is formed;

FIG. 2 shows a front perspective view of the test tube support formed from the sheet-like material of FIG. 1;

FIG. 3 is a plan view showing a sheet-like material from which another test tube support according to this invention is formed; and

FIG. 4 is a rear perspective view of the test tube support formed from the sheet-like material of FIG. 3.

FIG. 1 shows a sheet-like material, for example, a cardboard A, having a predetermined pattern from which a test tube support or stand is formed. The sheetlike material is rectangular in configuration. In the Figure, the opposite sides b, b of the rectangle are longer than the opposite sides a, a thereof. For example, the opposite sides a, a and b,b' are 230 mm and 308 mm, respectively.

A first folding line 1 is provided at a relatively wide interval of, for example, 86 mm from, and parallel to, the side a of the rectangle. A second folding line 2 is provided at a narrow interval of, for example, 17 mm from, and parallel to, the first folding line 1. A third folding line 3 is provided parallel to the second folding line and spaced a distance for example, 86 mm substantially equal to that of the first folding line. Fourth, fifth and sixth folding lines 4, 5 and 6 are provided parallelto the third line 3 and spaced a distance for example, 17 mm substantially equal to the distance between the first and second folding lines 1 and 2, from the third, fourth and fifth folding lines, respectively. Between the sixth folding line 6 and the side a is defined a relatively wide space 17 of, for example, 68

Between the side a and the first folding line 1, a plurality of rectangular apertures or windows 10, for example, five in number, are provided, for example, at equal intervals and each have opposite long side parallel to the sides b, b of the rectangle. The window 10 has opposite long sides of, for example 59 mm and opposite short sides of, for example, 34 mm. The distance between the long sides of the adjacent windows 10 is, for example, 10 mm and the distance between the side a and that short side of the window 10 which is closer to the side a is, for example, 17 mm. A section 9 defined between the side a and the folding line 9 constitutes the front wall of the test tube support. The number of windows 10, as well as the shape and size of the window 10, may be suitably selected. In this case, it will be necessary that, when the test tube support has been formed, test tubes etc. be clearly observed through the window 10.

At the middle portion of a wide section 11 between the second and third folding lines 2 and 3 is formed a first rectangular shaped support wall 15 defined by a seventh folding line 7 parallel to the third folding line 3, a corresponding line 12 cut on the third folding line 3 and opposite side lines 13 and 14 cut in a direction perpendicular to the third folding line 3. A slit l6 parallel to the side cut line 12 is formed in the support wall. The wide section 11 constitutes the outer wall of a rear panel of the test tube support. At the middle portion of a relatively wide section 17 defined between the sixth folding line 6 and the side a is formed a second support wall 21 defined by an eighth folding line 8 parallel to the side a, a corresponding line out in a direction parallel to the eighth folding line 8 and opposite side lines 19 and 20 cut in a direction perpendicular to the eighth folding line 8. The second support wall 21 has an earlike projection 22 adapted to be lockingly fitted into the slit 16 of the first support wall 15. The first and second support walls are both raised up in the same direction. In the Figure, the ear-like projection 22 of the second support wall 21 has a pair of recesses 23, 23 which facilitates a locking engagement with the slit 16 of the first support wall 15. The section 17 constitutes the inner wall of the rear panel of the test tube support.

Cut ends 29 and 30 may be provided adjacent to the cut lines 12 and 19, 20, respectively, so that the first and second support walls can be easily raised up from the plane of the cardboard when the test tube support is formed.

At a section defined between the two folding lines (in the FIGS. 1 and 2) which are located in the neighborhood of the seventh folding line 7 and on a side opposite to a side on which the cut line 12 is provided with the seventh folding line 7 as a reference, a plurality of openings 25, for example, 10 in number, equal in shape and size to each other are provided parallel to the side b of the rectangle. In the Figure, the opening 25 is rectangular in configuration. The rectangular shaped opening 25 has opposite long sides of, for example, 17 mm and opposite short sides of, for example, 16 mm. The long sides of the adjacent openings 25 are spaced, for example, 6 mm apart from each other. One side of the opposite short sides of the opening 10 is arcuate shaped. The shape of the opening 25 may be suitably selected. However, it is necessary that the opening 10 have such a size as to permit the test tube to be freely inserted and removed. At the section 26 defined between the folding lines and 6 are provided a plurality of openings 27 (in the Figure, in number) equal in size and shape to each other which are aligned with the plurality of openings 25, respectively. In the Figure, the opening 27 has a rectangular configuration having opposite long sides of, for example, 17 mm and opposite short sides of, for example, 16 mm. The size of the opening 27 may be suitably selected. However, it is necessary that the opening 27 have such a size as to permit the test tube to be freely inserted and removed. The sections 24 and 26 constitute the upper and lower compartmentalized walls, respectively, of the test tube support.

The test tube support is formed as follows.

The cardboard is folded in a direction along the first, second, third, fourth and fifth folding lines. Then, it is folded along the sixth folding line in a direction opposite to the direction in which it is folded along the above-mentioned folding lines. The section defined between the sixth folding line 6 and the side a is bonded to the section defined between the second and third folding lines 2 and 3, while the section defined between the side a and the first folding line 1 is bonded to the section defined between the fourth and fifth lines 4 and 5. The first and second support walls are respectively raised up and the ear-like portion of the second support wall is lockingly fitted into the'associated slit of the first support wall. The test tube support is so formed.

FIG, 2 is a perspective view showing the front of the test tube support so formed. As will be understood from the Figure the section 28 defined between the folding lines 3 and 4 constitutes the bottom of the test tube support.

FIG. 3 shows a second sheet-like material from which another test tube support according to this invention is formed. In the Figure, similar reference numerals are employed to designate lines or sections corresponding to those shown in FIG. ll. As will be evident from the Figure, the relative position of a folding line 7 and cut line 12' is reversed with respect to the relative position of the folding line 7 and cut line 12 shown in FIG. 1, while the relative position of a folding line 8' and cut line 18' is reversed with respect to the folding line 8 and cut line 18 shown in FIG. 1. FIG. 4 shows a perspective view showing the rear of a test tube support formed from the second sheet-like material. As will be easily understood from the Figure, a section 24 defined between first and second folding lines 1 and 2 constitutes the bottom of the test tube support; a section 28 defined between third and fourth folding lines, the upper compartmentalized wall of the test tube; and a section 26 defined between fifth and sixth folding lines 5, 6, the lower compartmentalized wall of the test tube.

As the sheet-like material, plastics may also be used in addition to a cardboard. In this case, each folding line may be formed by grooving.

Though the above-mentioned embodiments have been formed from the rectangular sheet-like material, this invention is not restricted thereto. For example, the rectangle may be modified by making one side positively or negatively arcuate or angular in configuration or making opposite sides selectively indented or notched.

As described above, the test tube support is easily formed from, for example, a cardboard stamped out to form a predetermined pattern. The test tube support according to this invention is inexpensive, light in weight and convenient for transportation. It is also convenient for storage since it is foldable.

Since the test tubes are supported by the upper and lower compartmentalized walls, there is no fear that any injury to the test tube will be caused during transportation. Furthermore, the kind, amount etc. of the content of the test tubes can be readily observed through the windows without the necessity of removing the test tube from the test tube stand.

The test tube support can be used as a package for test tubes or evacuated containers for blood collection by bringing the first and second support walls 15 and 21 into the initial position. In this case, the test tubes etc. can be safely transported without any injury. When the test tube support is used as a test tube stand, the support walls 15 and 21 need only to be raised up from the fourth and fifth sections for support. If the test tube support is soiled, it can be thrown away in view of its inexpensiveness.
