QM a PATENTED DEC 2 6 i972 SHEET 3 0F 3 INVENTOR. Womafi M. BEFFT We TT RQ QQ TRAY PACKAGE FOR TUBES BACKGROUND OF THE INVENTION The present invention relates to a tray which may be readily molded in one piece from moldablematerial to support and retain against breakage fragile tubular articles such as glass culture tubes and test tubes during shipment. It is desirable that the interior portions of such tubes be kept clean during shipment; accordingly, the tray of the present invention is provided with plug means for preventing the entrance of dust or other contaminants into the tubes during shipment from the tubing manufacturer to the packager.

Accordingly, it is an object of the present invention to provide a tray package for shipping tubular articles.

It is another object of the present invention to provide a trayfor shipping tubular articles which is inexpensive, can be readily molded in one piece and is contoured to provide at least a partial seal to the open end of the tubular articles retained therein.

Finally, it is an object of the present invention to provide a tube tray in which the cover flap may be retained in a closed position through cooperation with the flap member when the flap member is in its sealing position closing the ends of the tubes.

Other objects and advantages of the present invention will become obvious from the following detailed description taken in conjunction with the annexed sheets of drawings on which: I

FIG. 1 is a perspective view showing the tray in a fully open position as it comes from a molding machine;

FIG. 2 is a view similar to FIG. 1, showing tubular articles positioned in the tray and the flap folded to a position at which the plugs extend within the open ends ofsuch tubular articles;

FIG. 3 is a view similar to those shown in FIGS. 1 and 2 showing the tray in a fully closed position;

FIG. 4 is a sectional view taken through line 4-4 of FIG. 1; and

FIG. 5 is a sectional view taken through line 55 of FIG. 3.

Referring now to the drawings, there is provided a tray generally designated by the numeral having a bottom portion 12 with a plurality of elongated ribs 13 extending upwardly therefrom. The ribs '13 are in spaced parallel relationship to one another and are contoured to define therebetween grooves 14 in which tubular articles 15 may rest. Typically, tubular articles 15 packaged in the tray 10 will have a closed end 150 and an open end 15b. If desired, the ribs 13 may have interruptions or notches 18 formed therein to permit the tubular articles to be easily removed with ones finger.

Extending upwardly from the bottom 12 are a pair of elongated opposed substantially parallel sides 20. The sides 20 are disposed substantially at right angles to the lines followed by the ribs 13.

Also extending upwardly from the bottom 12 and extending between the sides 20 are a pair of elongated opposed substantially parallel ends 22. The ends 22 are substantially parallel to the ribs 13.

Preferably, the ends 22 will be provided with notches 23 in line with the row of notches 18 to facilitate removal of the end ones of the tubular articles 15. Each of the sides 20 and ends 22 has a-short flange portion 24 extending outwardly therefrom. Thus, the flange 24 extends completely around the periphery.

Extending outwardly from the flange 24 at one of the sides 20 is a cover 26. The line of juncturebetween the cover 26 and the flange 24 is'formed with a score line 27 which functions as a hinge to permit the cover 26 to be readily folded from the open position of FIGS. 1 and 2 to the closed position of FIG. 3. The cover 26 has a plurality of ribs 28 which extend toward the interior of the tray when the cover 26 is in a closed position. The ribs serve to assist in retaining the tubular articles 15 in afixed position. I

Extending outwardly from the flange 24 at the side 20 opposite the cover 26 is a flap 30. The flap 30 has a plurality of raised portions or plugs 31 which extend toward the bottom of the tray when it is in the open position of FIG. 1. As may be seen from viewing FIGS. 1 and 2, the flap 30 is foldable from its fully open position to a position at which the plugs 31 extend toward the cover side (FIGS. 2, 3 and 5). Thus the plugs 31 extend toward the interior when the tray is in itsv closed position. Thus,-it may be seen that the flap 30 is rotatable through an arc of substantially 270. The plugs 31 are sized to snugly fit within the open end 15b of the tubular article 15.. As a result, dust and other contaminants are prevented, or at least retarded, from entering the tubular articles 15 during shipment.

The flap 30 is integrally formed with the flange 24 with a score line 32 forming the juncture between the flange 24 and the flap 30. The score line 32 is relatively shallow and functions as a hinge. Spaced from and parallel to the score line 32 is an elongated indentation 33 which also functions as a hinge but which, as may be seen from FIG. 4, is much deeper than the score line 32. As can be seen from FIGS. 2, 3 and 5, as the flap 30 is folded, the elongated indentation 33 functions as the primary hinge by virtue of its depth and relative weakness to resist deflection as compared with the hinge formed by the shallower score line 32. Upon such initial folding, the opposite sides of the indentation 33 are thus brought into interfacial contact and form a locking tab 34 (FIG. 5) which functions to hold the cover 26 in a closed position. Thus, the tray 10 is self closing when tubular articles 15 are contained therein and no external or auxiliary means are required to keep it closed.

The tray 10 may be formed of any preferred moldable material such as a conventional thermoplastic and, preferably, is formed from a sheet of foamed polystyrene. As may be appreciated from viewing FIG. 1, it may be readily vacuum formed by conventional forming techniques.

I claim:
