PATENTED SEP28 um 360K706 sum 2 or 3 TRAY FOR PACKAGING U-SIIAPED BULBS BACKGROUND OF THE INVENTION This invention relates to a tray for packaging products such as U-shaped fluorescent lamp bulbs. Such products which are of fragile nature and irregular shape are difficult to store and transport without damage and breakage of the product. For example when a plurality of such products are packaged atop each other the products must be isolated to prevent the fragile bulbs from smashing into each other when the package is jolted. More over frequent breakage is caused with conventional packaging arrangements by impact imparted to the outside of the shipping box or carton. A further consideration in packaging these fragile products is to accommodate the packaging tray for automatic loading without damage to the product.
SUMMARY OF THE INVENTION An object of this invention is to provide a packaging tray for fragile products such as U-shaped fluorescent lamp bulbs.
A further object is to provide such a tray which effectively isolates the bulbs from each other to eliminate the danger of the bulbs smashing into each other.
A still further object is to provide such a tray which readily absorbs any impact imparted to the outside of the shipping box during storage or handling.
In accordance with this invention a molded tray made for example from a pulp or foam plastic material includes a bottom wall having upwardly extending side walls which terminate in a peripheral rim. The tray includes at least one U- shaped pocket for receiving a portion of the U-shaped bulb. The legs of the pocket terminate at the rim of the tray while the bight terminates short of the rim. Upstanding crushing resistance members or ribs are on the bottom wall to define and isolate the pocket. A plurality of spaced resilient pads are in the pocket with the crushing resistance ribs extending above the bottom wall a greater amount than these resilient pads.
The pocket may include leg extensions adjacent the bight so that the intermediate bend of a bulb may be inserted in the bight of one tray and the legs thereof inserted in the leg extensions of a like coplanar tray. The bulbs may be stored and transported by inverting a pair of the trays so that each bulb is sandwiched between two pairs of trays with the bright portion of the bulb between one pair and the leg portions between the other pair of trays.
In an alternative packaging arrangement where less protection can be tolerated each bulb may be rested upon two trays as indicated above but with the upper trays being disposed in the normal fashion rather than being inverted. Thus the upper tray may also hold a further bulb.
Advantageously, the corners of the tray may be beveled to facilitate automatic loading.
BRIEF DESCRIPTION OF THE DRAWING Novel features and advantages of the present invention will become apparent to one skilled in the art from a reading of the followed detailed description in conjunction with the accompanying drawing wherein similar reference characters refer to similar parts and in which:
FIG. I is a plan view of a packaging tray in accordance with this invention with a pair of bulbs indicated therein in phantom;
FIG. 2-3 are side and end elevation views of the tray shown in FIG. 1;
FIGS. 45 are cross section views taken through FIG. 1 along the lines 4-4 and 5-5, respectively;
FIG. 6 is a cross-sectional plan view of a set of trays in one packaging arrangement;
FIG. 7 is a cross-sectional elevation view of the set of trays shown in FIG. 6;
FIG. 8 is a cross-sectional viewtaken through FIG. 7 along the line 8-8;
FIG. 9 is a plan view of a set of trays similar to FIG. 6 in accordance with a further packaging arrangement; and
FIG. 10 is a cross-sectional view in elevation of a still further packaging arrangement.
DETAILED DESCRIPTION OF THE INVENTION FIGS. 1-5 illustrate a packing tray 10 formed in accordance with this invention. As indicated therein tray 10 includes a bottom wall 12 having side walls 14 extending upwardly therefrom and terminating in peripheral rim 16. Tray 10 also includes a pair of U-shaped bulb receiving pockets or areas l8, 18. Each pocket 18 has a pair of parallel leg portions 20 joined together by bight portion 22. Leg portions 20 terminate at rim 16 while bight portion 22 terminates short of rim 16. Thus a U-shaped bulb 24 may be conveniently inserted in pocket 18 with the legs 26 of bulb 24 extending beyond the leg portions 20 of pocket 18.
Pocket 18 also includes parallel leg extensions 28 in line with leg portions 20. As shown in FIG. 6 extensions 28 of one tray thus receive the remote ends of the bulb which is held in another tray of identical construction but arranged in mirror relationship thereto. Accordingly, the same pocket 18 may receive either the bight or the remote ends of the leg of the U- shaped bulb.
As illustrated in FIG. 1 tray 10 is particularly designed to universally support either ends of two U-shaped glass fluorescent lamp bulbs lying side by side. As can readily be appreciated tray 10 may be easily adapted for holding only one bulb or may be adapted for holding more than two bulbs in accordance with the number of pockets 18 provided thereon.
In the arrangement shown in FIGS. 6-8 bight portions of two bulbs are placed in one tray 10 and another like tray is inverted over the same end of the bulbs in face-to-face relationship to the first tray thereby sandwiching the U-ends of the bulb between the two trays. The opposite or straight ends 26 of the bulbs are likewise sandwiched between two identical trays. The assembly of two bulbs and four trays is packed with other like assemblies into for example a cardboard box or carton 30 to completely enclose the assembly.
Preferably the sets of trays are dimensioned to abut against each other and completely enclose, isolate and cushion each tray. Under certain circumstances, however, where the bulbs are very long, the trays may be somewhat spaced from each other (as in FIGS. 6-7) thereby concentrating the protection at the extreme end portions and the bent portions of the bulbs.
Trays l0 advantageously function to suspend and isolate the fragile bulbs 24 away from the walls of box 30 so that the resilient fibrous pulp or foam plastic material will absorb any impact imparted to the outside of box 30 during shipping, storage or handling. Trays l0 likewise prevent the bulbs 24 from smashing into each other when the package is jolted. The corrugated wall structure of tray 10 which receives the outer ends 26 of bulbs 24 is designed to maximize the crushing resistance of the tray from an endwise direction equally protecting the pin ends 32 (FIG. 7) of the bulbs as well as the bent U- shaped ends.
The outer sidewalls 14 of tray 10 are similarly ribbed or corrugated to afford crushing resistance to the resilient pulp or foam material. The bulbs are additionally supported upon raised resilient pads 34 to space the bulbs from the bottom wall 12 of the tray 10. As best shown in FIG. 1 cushioning pads 34 are spaced in such a manner as to be disposed in the curved as well as the straight portions in the bulb receiving pocket 18. The rib structure 36 throughout the central portion of tray 10 serves to both locate and cushion the bulbs 24 laterally as well as to add strength and rigidity to the package. Additionally, strengthening ribs 38 are provided between the straight leg portions 20 and each bulb-receiving pocket 18.
As also shown in FIG. 1 the comers 40 of tray 10 are beveled to provide a lead-in, thus facilitating automatic loading of the tray assemblies into the cardboard boxes 30 by thrusting the entire assembly into box 30.
FIG. 9 shows an alternative packaging arrangement. As indicated therein bulbs 24, 24 are disposed in opposite orientation to each other. ln other words the bent or U-end of one bulb and the straight end of the other bulb 24 are in the same tray. This method of placement equalizes the height of each end of package since the U-bend tends to be warped out of the basic plane of the straight legs which creates a thicker package in the bent end particularly when packed in several layers into a shipping container.
FIG. 10 illustrates another packaging arrangement wherein a set of bulbs 24a are placed in a set of trays 10a with the adjacent tray 10b being in the normal rather than inverted position for holding the further bulb 24b Similarly any number of additional trays 10:: etc. and bulbs 24c etc. can be arranged therein with the topmost tray 10c being inverted to isolate the topmost bulb 24d (which rests in tray 10d from container 3% This arrangement is advantageous where slightly less protection can be tolerated thus permitting a larger number of bulbs to be packaged in container 30a Tray 10 thus effectively cushions and isolates fragile U- shaped articles from each other and from the shipping carton while providing the desired amount of reinforcement thereto. With the various packaging arrangements illustrated for example in H65. 7, 9 and 10, tray 10 can be utilized in conjunction with identical trays to satisfy the needs dictated by the type of protection desired for the packaging of specific fragile articles.
