preferably heavy cardboard. .Strip3l is folded. along transverse fold lines ,32 through 3 8 to provide sections 3la through 3|h. Sections 3112 and 3|c are equal in length and arranged parallel to tray bottom 2| (Fig. 2), being interconnected at i one end of the tray by a vertical wall formed by narrow section 3|b. Section am, as best seen in Fig. 2,.lies a ainst traybottomor base 2|, whereas, sectionftf'ljc'lis i'nfspaced relationjtothe tray bottom, being supported'at its innermost end by the vertical wall'formed by narrow s'ection.3|d. The next 'sectiontle, likewise lies against tray bottom 2|, and it "will be noted that section 3|a forms a limit, stop for'movement of section 3|e'to the left (Fig. 2) Sections3 If and My arejfolded about'line 31 to form an' inverted V, which is held in properly supported position by section 3|h, lyingagainst tra bottom 2| and abutting right end wall 2 2; and section 3|a, abutting left end wall 22 and limiting leftward movement of, section 3|e.,

Before strip 3| is folded as described, it is provided with cut-outs to receive syringe H1 and hold the same against movement within carton 20.1 A cut-out 40 in section 3|c is shaped'to receive plunger |3 and the inner end of barrel ll, having lateral extensions "4|, 4| receiving flange I4 and lateral extensions, 42 receiving flange- |6.'" The longitudinal spacing of e'xtensions H from extensions' 42 is greater than the spacing of flanges MandiG when plunger |3is fully pushed into barrel it. Consequently, when the flanges are engaged in their respective cut-out extensions, :theainner. end' of plunger I3 is maintained in spaced. relation to the bottom of barrel thus preventing accidental'contact of'these elements. r Cut-out 4|).is continued into a cut-out '43 extending the full depth of section. 3 Id, so that the outerendofisyringe l0 rests on folded under extension 3 a. This latter forms a reinforcing and cushioning layer ontray bottom 2| to protect the syringe against shock.

Identical and interconnected cut-outs .45, 45 are formed insections 3| f and 3|g, respectively, having are shaped outer ends conforming to the surface of barrel The inner, connected ends ofthe cut out have alateral dimension less than the outer. diameter of barrel so that the cutouts- 45, lelcokjn pl n someWhat like a dumbbell.

Cut- outs 45,46 do not extend the full, depth of sections 3 f, 3|g, so that barrel is supported in'sp'aced parallel relation to .tray

. when-sections ftf lf andg 3|gare folded-about The syringe may be readily engaged in the insert 30, as shown in Figs. 1 and 2, and the cutouts are so related to the end walls 22 of tray so that the outer end of plunger l3 and the nozzle l2 are held firmly in spaced relation to the end walls 22. While flange I6 rests on section 3 la, it is; protected as this section forms acushion on tray bottom 2|. The rest of the syringe is firmly held in spaced parallel relation to tray bottom 2| and to the upper edges of the tray side and end walls.

The insert is inexpensive, efficient, and easily used. The transversely extending trough formed by sections 3|d, 3|e and 3| allows the syringe to bereadily grasped for insertion or removal.

While a specific embodiment of the invention has been shown and described in detail to illustrate'the application of the invention principles thereto, it should be understood that the invention maybe otherwise embodied withoutdepartingfrom s'uchp'rinciples' 1' 'Whatis claimed is: i
