LARRY J. BUDD ill VIII] BY w L I L I' I I 22 F169 X X ATTORNEYS United States Patent Filed Get. 3, 1962, Ser. No. 2281174 11 Claims. (Cl. 229- 14) The present invention relates generally to a cushioning pad for insertion into a carton for end engagement with an article to be disposed in the carton. This invention further relates to a method for manufacturing the cushioning pad.

In an exemplary application of this invention, a television receiver including a cabinet and receiver apparatus therewithin, underlying the cabinet to support the cabinet bottom wall is spaced in relation to the container bottom as shown in the US. Patent N 0. 2,895,661. The cushioning pad is adapted to be disposed over the cabinet top and carries means depending therefrom for engaging upper portions of the front wall, rear walls and side walls of the cabinet to support the same in spaced relation to the vertical walls of the container and also to protect the edges of the cabinet at the inner sections of the top wall with the front wall, rear wall and side wall.

The cushioning pads herein disclosed are improvements upon the cushioning pad disclosed in my aforesaid patent whereby the instant cushioning pads can be more readily manufactured at a reduced cost. The instant cushioning pads are sturdier and stronger than the cushioning pad disclosed in my aforesaid patent according to important features of this invention. To attain this end, a paperboard plate is secured within a central pocket of the pad and which pad is peripherally defined by rectangularly arranged, reinforced cushioning tubes. The outer edges of the paperboard plate are engaged in edgewise reinforcing relation against the rectangularly arranged tubes for maintaining the tubes in an upright position relative to the central portion of the cushioning pad. In order to further reinforce the cushioning pad, side tubes are provided with inside side walls having notched areas which are engaged against inside and bottom side walls of the rear .tube and with bottom walls of the side tubes being secured in lapped engagement with a bottom wall of the rear tube.

There are two types of cushioning pads disclosed herein, one of which is particularly adapted for being mounted on a television apparatus and the other of which is suited for being mounted on a stereo cabinet. It will be appreciated that the television tube extends rearwardly of the television cabinet and this tube must be protected by the cushioning pad. Since a stereo cabinet does not have a television tube, the front and rear tubes on the pad may be manufactured identical to one another.

It is an important object of this invention to provide a new and improved cushioning pad which may be more easily manufactured at a reduced cost.

Still another object of this invention is to provide a new and improved cushioning pad which is sturdier than similar pads previously used.

Yet another object of this invention is to provide a new and improved method for manufacturing the cushioning pads described above.

A still further object of this invention is to provide a new and improved cushioning pad having a central plate with its peripheral edges butt engaged with the inside walls of the tubes disposed on one Side of the pad and further with the plate edges serving to hold the inside Walls in engagement with the reinforcing means disposed within the tubes.

Still another feature of this invention relates to a new and improved method of securing a paperboard plate with ice a cushioning pad to hold rectangularly arranged reinforcing tubes in upright position on the pad. Other objects and features of this invention will more fully become apparent in view of the following detailed description taken in conjunction with the accompanying drawings illustrating several embodiments and in which:

FIGURE 1 is a view illustrating a sheet or blank from which the cushioning pad is formed and with a paperboard plate being superimposed thereof for illustrating its relative position with respect to the sheet;

FIGURE 2 is a bottom view of a cushioning pad, in accordance with the principles of this invention;

FIGURE 3 is an end view of the cushioning pad shown in FIGURE 2;

FIGURE 9 is a bottom view of a modified type of cushioning pad; and

FIGURE 10 is a fragmentary end view of the pad as viewed on the line X-X looking in .the direction indicated by the arrows as shown in FIGURE 9.

In FIGURE 8 the reference numeral 7 indicates a paperboard carton 7 having a television receiver 8 mounted therein and with a cushioning pad or cushioned packing insert E mounted on top of the receiver 8 for protecting the receiver within the carton 7 during shipment. The cushioning pad 9 in FIGURE 8 and the cushioning pad 9' in FIGURE 9 and the methods of making the same embody the inventive concepts presented herein.

In general, each of the cushioning pads may be formal from relatively rig-id form-sustaining sheet material and preferably for an inexpensive expendable material such as paperboard, fiberboard or the like. The pads are formed by making bends at score lines which may be scored by marking the blank or preferably by actual indentation of the blank, especially when the blank is of paperboard or a like material, but it will be appreciated that marking or indentation is not necessarily required and the terms scoring and score line are therefore used in a figurative sense to indicate the position of the bends.

The cushioning pad 9 is formed by cutting, scoring and folding a cushioning pad blank or sheet 10 in the manner hereafter described. The blank 10 includes a central pad portion or area 11 having four blank or

sheet margins

12, 13, 14 and 15. The sheet margin 12 is scored along score lines 16, 1'7 and 18 to provide flaps or

sections

19, 20 and 21. The flap 17 is provided with a notch area 22 having a configuration approximating the peripheral dimension of the rear tubular disclosure hereafter described. The

sections

19, 20 and 21 are folded at the

score lines

16, 17 and 18 about a reinforcing insert 23 to form a reinforced side tube or tubular enclosure 24. The packing may be comprised of any suitable material such as layers of corrugated paper with the corrugations eXtend ing transversely of the tube 24. Other suitable types of reinforcing inserts may be used, if desired.

The margin 13 is scored with score lines being indicated 39. A reinforcing insert 31 which is substantially identical to the insert 23 is adapted to be disposed interiorly within reinforced rear tube or tubular enclosure 32 upon folding the

tube sections

28, 29 and 30 at the

score lines

25, 26 and 27 about the insert 31.

The margin 14 is scored as indicated by

score lines

34, 35 and 36 to form

tube sections

37, 38 and 39. The tube section 39 is provided with a notch area 40 of the same type as the notch area 22 for snug engagement with tube flaps or

sections

29 and 30 on the tube 24. The margin 14 is adapted to be folded along the score lines to turn the

tube sections

37, 38 and 39 about a reinforcing insert 41 to form a reinforced side tube or tubular enclosure 42.

The fourth margin 15 is provided with a T-shaped notch area 44 providing a pair of pad blanks with the first pad blank being scored as indicated by

score lines

45, 46 and 47 to form

pad sections

48, 49 and 50. These pad sections are folded about a reinforcing insert or filler 51 to form a reinforced front tube 52. The other pad blank is scored along

score lines

54, 55 and 56 to form

pad sections

57, 58 and 59. These pad sections are folded about a reinforcing insert 60 to form a reinforced front tube 61.

As the reinforced

tubes

24, 32, 42, 52 and 61 are formed, the reinforcing inserts are preferably glued by a suitable glue such as a vegetable base glue with the sur rounding flaps as well as the central pad portion or area 11 for holding the tubes in a plane generally normal to the plane of the central pad portion 11. In order to further rigidify the

tubes

24, 32 and 42, the tube flaps or

sections

20 and 38 on the

side tubes

24 and 42 are glued to the flap or section 29 on the rear tube 32. Still further, in order to rigidify the juncture between the

tube

24 and 52 and the juncture between the

tubes

52 and 61, the flaps or

sections

21 and 50 are glued together and the flaps or

sections

39 and 59 are glued together as shown in FIGURE 3.

In view of the foregoing it will be appreciated how the cushioning pad 9 can be formed from a reduced amount of material and yet be of a very rigid construction. In order to further rigidify the pad 9, and according to still further important features of this invention, a paperboard reinforcing plate 63 is pressed against the central pad portion or area 11 and preferably secured thereto by means of glue or the like in such manner that its

marginal edges

64, 65, 66 and 67 are engaged with the inner side walls defined by the flaps or sections 21, 3t), and 39 as well as against the

tubes

52 and 61. The plate 63 is cut to a dimension which corresponds precisely to the dimension of the top of the television receiver 8. By securing the plate 63 with the pad 9 in the manner described, the

tubes

24, 32, 42, 52 and 61 are all reinforced as a result of the engagement of the marginal edges of the plate 63 therewith. The marginal edge 67 engages with end edges of the

tubes

52 and 61 rather than with the side walls of the tubes and it will be appreciated that such engagement serves to rigidify the pad 9 to better enable the pad to resist forces tending to displace the tubes with respect to the central pad portion or area 11.

Shown in FIGURES 9 and is the modified cushioning pad 9. This pad 9 is identical to the pad 9 except that the

tubes

52 and 61 found on the pad 9 are replaced by a reinforced side tube or tubular enclosure 32" which is identical to reinforced side tube or tubular enclosure 32'. The tube 32' is identical to the tube 32 previously described in connection with the pad 9. In order to further rigidify the pad 9, opposite ends of side tubes 20' and 42 are notched as indicated at 22-22 and 4040' to enable the tube side walls to be fitted about rear and 'front tubes 32' and 32" for reinforced engagement therewith. It will thus be appreciated that the opposite ends of the

tubes

20 and 42 are engaged in fitted relation in glued assembly with rear and front tubes 32' and 32" in contrast to the pad 9 where the

tubes

20 and 42 were only notched at one end for engagement with the rear tube 32.

The pad 9 is adapted for use with a conventional cabinet whereas the pad 9 is adapted for assembly with a television receiver cabinet 9. In this regard, the

tubes

52 and 58 are adapted to extend rearwardly of the television receiver cabinet 8 to protect the television tube which extends rearwardly behind the television receiver cabinet on most conventional types of television receiver sets.

It will be understood that modifications and variations may be effected without departing from the scope of the novel concepts of the present invention.
