United States Patent 3,227,357 CONTAINERS FOR TV BULBS, TUBES AND THE LIKE Eugene J. Knapp, Corning, Lewis F. Reas, Big Flats, and Mitchell Sayers, Corning, N.Y., assignors to Corning Glass Works, Corning, N.Y., a corporation of New York Filed Apr. 30, 1964, Ser. No. 363,937 13 Claims. (Cl. 229-39) This invention relates to improvements in the art of containers, especially those suitable for packing and shipping TV bulbs, tubes and the like.

In the known art of packing a number of TV tubes in a single package, prior containers have been relatively complex in assembly and have been built from high cost materials due primarily to the protection requirements for relatively heavy and expensive television glassware and the strength requirements for rehandling and reshi pping the glassware during the processing.

Corrugated paperboard is known as an excellent material for glassware packaging not only because of its low cost but also its good cushioning qualities and the fact that it can be changed to accommodate new or revised ware configurations with relative ease in making the required tooling changes. Furthermore, corrugated paperboard can be readily obtained and is inexpensive to ship or store in the flat or knocked down state and can readily be printed upon.

Paperboard cartons for packing multiple television tubes are known in the art; however, these prior cartons are complicated, expensive and difficult to pack. They are made up of alarge number of different pieces of corrugated paperboard (e.g. 26 pieces for an 8 tube carton) and some of these many pieces are frequently ruined in storing or packing, making assembly and inventory most difiicult. Most of the individual pieces require folding, stapling, and have a complex interrelationship. Because of the foregoing, these individual pieces are often misassembled or left out resulting in a carton containing improperly braced and supported glassware. For different size cartons utilized for packing different numbers of tubes, improper pieces may be substituted at different times with similar results. It is therefore an object of this invention to provide a TV glassware carton made of a unique shape using significantly less material, which is easier to pack and repack due to its being a corrugated paperboard blank foldable to supply maximum support and bracing, and having a minimum number of pieces all supplied from the same blank, whereby assembling and handling are greatly simplified and material costs are drastically reduced.

Television glassware is presently packed in bulk cartons within economical shipping dimensions and then the packages of the glassware TV bulbs are shipped to tube manufacturers for finishing and the installation of cathode ray guns. The resulting finished TV tubes are then repacked in the same cartons and shipped to the television set makers where the tubes are assembled into cabinets to make finished television sets, and the packing material is discarded by the set manufacturer. It is a further object of this invention to provide a container for television tubes and the like which is adapted for use in the shipping of both glassware bulbs and the finished tubes to a television set maker, while at the same time being inexpensive enough to allow discarding of the material.

The foregoing and other objects, features and advantages of the invention will be apparent from the following more particular description of a preferred embodiment of the invention, as illustrated in the accompanying drawings.

FIG. 9 is a sectional view taken along line 99 of FIG. 8.

FIG. 10 is an end sectional view showing the carton with TV bulbs loaded therein for shipment to a TV tube manufacturer.

FIG. 11 is a further sectional view somewhat similar to FIG. 10 but showing a finished TV tube and the condition of the carton in shipping the finished tube to a TV set maker, in which certain filler pieces have been discarded.

Ingeneral, this invention provides a container for TV glassware formed from a single piece blank with the optional use of certain auxiliary filler pieces which may be struck from within rectangular confines of the original blank. The container is a rectangular parallelepiped with top and bottom flaps extended in a unique configuration to brace, support, protect and position the glass TV bulbs or tubes. Maximum strength is obtained from the position of the folds and therefore the positions of the supporting flaps. Overfolding top and bottom flaps of the containers completely close the carton to prevent entry of foreign objects, and these flaps further include interlocking tuck flaps to further contribute to overall strength and rigidity. The interrelated fiapsstiffen the structure and hold individual pieces of ware away from each other. Filler pieces necessary to build up extra thickness of corrugated board for cushioning are made as parts of the overall blank and are left attached to the carton blank until required for bulb packing and assembly, thereby eliminating any need for separate inventory of filler pieces. Because of its relatively large size and to facilitate fabrication, handling and assembly, a carton blank may be made from two identical blank halves which may be fastened together.

Referring now to the drawings for more detail of the structure, there is shown in FIG. 1 a completed and folded carton 12 for containing and protecting four TV bulbs or tubes. To illustrate the modular concept of this invention, four cartons 12 such as shown in FIG. 1 may be strapped by steel strapping 13 to a pallet 15 or the like for handling as a palletized load.

A blank 14 from which the corrugated container of this invention is formed is shown in detail in FIG. 3. The blank may be formed from two identical blank halves 16, 16' and these halves may be secured together at both ends by any suitable adhesive tape strips 20 and 22, such as cloth, paper, or reinforced materials. Since blank 16 is identical to blank 16', only blank 16 will be described in detail in the blank state and identical reference numerals primed will indicate the corresponding components, fold lines, etc., of blank half 16.

The blank half 16 includes a relatively large rectangular side panel 24 separated by a fold line 25 from an end panel 26. Foldable from the end panel 26 are top and bottom flaps 28 and 30 respectively, defined by fold lines 27 and 29, respectively. Adjacent the long sides of panel 24 are panels 32 and 34 separated from panel 24 by fold lines 31 and 33. Support flaps 36 and 38 extend outwardly from panels 32 and 34, and are foldable therefrom along fold lines and 37. Flap 36 includes a pair of fold lines 39 and 41 and a notch at its outer end. The outer edge of flap 38 includes a similar U-shaped notch 42 adapted to mate with notch 40 and a single fold line 43.

Adjacent to flaps 36 and 38 and foldable from panels 32 and 34 are further support flaps 44 and 46. These flaps also include U-shaped notches 50 and 52 in their outer edges. Flap 44 is foldable along fold lines 45, 47 and 49, which are identical to fold lines in flap 46.

Adjacent flaps 44 and 46 are another set of ware supporting flaps 52 and 54, flap 52 being foldable along fold line 51 and including further fold lines 53 and 55; while top flap 54 is foldable along fold line 57 and includes a further fold line 59. The outer edges of these flaps include U-shaped notches 56 and 58, respectively.

End fiap 60 is foldable from panel 32 along fold line 61 and includes further fold lines 63 and 65, top end flap 62 is identical and has similar fold lines. The flaps 60 and 62 further include U-shaped notches 64 and 66, respectively. It it noted that the bottom support flaps 36, 44, 52 and 60 include a pair of further U-shaped registry depressions 67 and 69 adjacent and on boths sides of U-shaped notches 40, 50, 56 and 64 therein.

The outer bottom flap 30 includes infolding tuck flaps 68 and 70 while the outer top flap 28 includes similar infolding tuck and interlocking flaps 72 and 74.

Interlocking and support flaps 76, 78, 80, 82, 84 and 86 are folded from fold lines 75, 77, 79, 81, 83 and 85, respectively, to provide support as will be explained.

As can be seen from the blank shown in FIG. 3, further components can be struck from the same generally rectangular piece of cardboard, these components are known as filler pieces and in the embodiment illustrated are filler pieces 88, 90, 92, 94, 96, 98, 100 and 102. Different shaped filler pieces may be used for different configuration of the TV tubes, as they change the ditferent filler pieces would be used differently.

The filler panels 88, 90, 92, 94, 96, 98, 100, 102 illustrated are specifically for a 23" 92 LW bulb pack and could be eliminated or altered for other types of tubes. The filler pieces are cut and creased to be made into the innerpacking filler pieces during final assembly of the pack. The filler pieces are secured to the rest of the blank during fabrication and fiat blank shipment by nicks or interrupted cuts. Therefore, the original rectagnular blank is shipped complete as illustrated in phantom lines of FIG. 3. The pieces are then torn from the rest of the blank during set-up or assembly of the pack, thus re ducing the possibility of lost or mislaid components.

The carton in its erected position is best described by describing the assembly or set-up operations and the loading of the TV bulbs and tubes into the carton.

The carton is first squared up in a somewhat conventional manner. Referring to FIG. 4, panels 24 and 26 are folded at right angles to one another as illustrated by panels 24 and 26. Similarly, panel 32 is folded at right angles to panel 24. Bottom flap panel 30 is then folded at right angles to end panel 26 as shown in FIG. 4, and when panel 26 is folded at right angles to flap 24, the bottom flaps 30 and 30 will underlie flaps 32, 32' and provide the outside bottom of the carton. Fold lines 35, 35, 45, 51, 51, 61 and 61 are folded as shown in FIG. 4 so that their corresponding panels extend generally upwardly. The tuck flaps 68, 68 and 70, 70 on panels 30 and 30' are folded into the space below the 4 base of flaps 44, 44' and then the bottom panels 30 and 30 are taped in place.

The next step is folding the additional fold lines 39, 39, 41, 41, 47, 47, 53, 53, 55, 55, 63, 63' 65 and 65. Matching panels 36-60, 44-52, 52-44, and 60-36' are aligned face to face as shown in FIG. 5 with the edge notches 67, 67, 69, 69', assisting in exact alignment. The panels are then secured together by any suitable means such as foldably locking cleaned out material, or stapling them together with staples 18.

The flaps 68-68' and 70-70 will cause the lower end of panels 6060 and 44-44 to be generally perpendicular to panel 32, see FIGS. 4, 5, 6 and 7. Meanwhile the corresponding matching panels 36-36 and 52-52 will lie at an obtuse angle to panel 32. The alternate protruding flaps allow the glassware to be supported in staggered relation and prevent adjacent pieces of glassware from touching.

The interlocking side tabs 76, 78, 80, folded from fold l liges 75, 77, 79, support their opposing counterparts 76',

The filler pieces 98, 98 are then folded into a square section and placed in opposite corners between the panel 62 and panel 24 as shown in FIGS. 6 and 7. The score lines allow panels 98, 98 to be so folded.

It is noted that all flaps constituting the top of the glassware support and bracing, namely flaps 38, 38, 46, 46, 54, 54, 62 and 62 are folded back out of the way to facilitate the remaining assembly and loading of the TV glassware. FIG. 5 shows the assembly at this stage.

The special filler pieces illustrated in FIG. 3 are for packing 23 92 LW TV bulbs, and when the bulb is shipped from the glass manufacturer to the tube manufacturer for the insertion of the cathode ray gum, etc., the filler pieces are utilized in the following described manner.

It has already been noted above that filler pieces 98, 98' are folded and placed in opposite corners as shown particularly in FIG. 8. Filler pieces 88, 88 and 100, 100' are placed on the bottom panel 32, 32 adjacent panels 36 36, 52, 52. To provide a cushioning effect for the glassware, these panels may be folded as shown in FIGS. 7, 9 and 10, or may be used in single thickness as desired. Filler pieces 90, 90, 92 and 92 are placed in the large notches at the outer end of the panels 36, 44, 52 and 60, and are braced by the tongues on filler pieces 88, 88, and 100, as shown for example in FIG. 7.

The four TV bulbs to be placed in the carton may then be loaded in the carton in a staggered manner as shown in FIG. 8. The notches in the flaps which have been stapled together brace and support the neck of the bulbs while the face of each bulb rests on the cushioning filler pieces, as shown in FIGS. 9 and 10. In other words, supporting flaps 36, 60, 44, 52, 52, 44, 60, 36 hold the yoke sections of the TV bulbs firmly and they support the bulb on the edge of the face by filler pieces while the panels 36, 36, 52, 52, lying at obtuse angles will rigidly support the back of the bulb, see FIGS. 9 and 10. Corner pads 96, 96' are then folded and inserted in opposite corners between the carton and the tube face sides as shown in FIG. 8. Pieces 102, 102, 92 and 92 are used as pads for steel strapping to secure four of these cartons to the wooden pallets as shown in FIG. 2.

The next step in assembly with the ware loaded in the open top carton is the folding of notched flaps 38, 38, 46, 46, 54, 54, 62, 62 into position so these flaps lie between the glass tube faces in the same manner as the bottom panels. The outer ends of flaps 46, 54', and 62, 38 are inserted over the glass neck outside the outer end of stapled flaps 44-52 and 60-36' as shown for example in FIGS. 10 and 11. The alternate flaps 38, 62 and 54-46 are also folded over the funnels and tucked to the outside of their corresponding previously stapled flaps 36-60, 52-44. When all the flaps are in place, the outer top flaps 28, 28 are folded down with the tabs 72, 72, 74, 74, folded and inserted next to the lower end of flaps 46, 46', 62 and 62 similar to that arrangement for the bottom of the carton.

The outer top flaps 28, 28 are then squared up and taped in a closed position by tape 104, like the bottom flaps. See FIGS. 1 and 2. FIG. 2 shows two such loaded cartons stacked on each wooden pallet with two more on top, and with the pieces 92, 92, 102 and 102 used as corner pads for the strapping. This provides a pallet pack for sixteen TV bulbs or tubes. Rail car and truck dimensions dictate pallet sizes for economical shipping.

When it is desired to remove the glass TV bulbs, at the gun manufacturers plant, unpacking is accomplished by cutting the steel strapping 13 and the top tape 104, then opening the top flaps 28, 28, and pulling up on the flaps 38, 38, 46, 46', 54, 54, 62, 62 to expose the ware for removal from the carton.

After the tube manufacturer has inserted the ray gun and otherwise manufactured the glassware into a completed TV tube he may use the same carton for repacking the tubes without the use of filler pieces 98, 98', 100, 100, 88, 88', 90, 90 and 94, 94' due to the size change caused by the addition of laminated cap 106 to the tube. Corner pads 96, 96' and the four strap pads 92, 92', 102, 102' are reused in the repa-cking of the completed bulb as shown in FIG. 11.

While the invention has been particularly shown and described with reference to preferred embodiments thereof, it will be understood by those skilled in the art that the foregoing and other changes in form and details may be made therein without departing from the spirit and scope of the invention.
