United States Patent ,SHIPPING CONTAINER AChester E. Plevyak, Plainfield, NJ., assignor to Westinghouse Electric Corporation, East Pittsburgh, Pa., a corporation `of Pennsylvania Filed `May 6, 1957, Ser. No. 657,354

4 Claims. '(Cl.12291'4l) invention relates to containers ,for holding fragile articles, whereby they may be shipped without danger of lbreakage or other damage thereto.

viding a carton and insert cushion member therefor, each formed from a unitary piece of material.

It is still another object of the invention to simplify lthe design of shipping containers for fragile articles by eliminating some of the cardboards previously used, while 4at the ysame time-ensuring proper clearance for the article to be shipped. Thisresults in a saving of material, savings in space necessary to stock the parts, and an increase `in the speed of packaging. Also, the design provides better protection for the article to be shipped.

*These and other objects of the invention are effected by my invention, as will -be apparent from the following description taken in accordance with the accompanying ydrawing throughout which like reference characters 1indicate like parts, and in which:

tainer and cushion member showing the manner in which `they cooperate with eachother in assembled form.

Referring to Figs. l and `2, the container is shown in the formof a carton 10. The carton iis made of conventional single wall corrugated cardboard and is formed by creasing and cutting a single sheet of the cardboard as shown in Fig. 2. The finished carton comprises Vside walls 11 and 12,

end walls

13 and 14, a top wall 15, and a bottom wall 15 comprising flaps 16a-16d. The top wall 15 includes an inner Wall member 17 and an outer wall member 18 folded in reverse directions across the top of the carton.

The `inner top wall member 17 is comprised of an inner ap member 19 and an outer flap member 20. One side of the inner wall member 17 is movably secured to the .sidewall 12. The inner flap member 19 is folded 'under the flap member 2@ so that the other `side of the Wall member 17 lies closely adjacent to the side wall 12 and the wall section 17 forms a double thickness of the cardboard material.

One side "of the outer top wall member 18 is movably The wall member 18 is folded over the inner Wall section 17 so that the top wall 15 comprises three thicknesses of cardboard material.

2,941,709 Patented June 2l, 1960 ICC The

end walls

13 and 14 are provided with

top flaps

21 and 22, respectviely. One side of the top flap 21 is movably secured to the end vwall 13 and one side of 4'the top flap 22 is similarly secured to the end wall 14. The

top flaps

21 and 22 are provided with outer, inner and

intermediate ap portions

23, 24 and 25, respectively.

The cartion is formed from a single blank of corrugated cardboard material and cut to the blank form shown in Fig. 2. The side walls 11 and 12 and the

end Walls

13 and 14 are formed by folding the blank on the longitudinal parallel fold lines 26 the top wall by folding 'the blank on the fold lines 27, and the lbottom wall by folding the blank on the fold lines 24S. The inner top wall member .17 is bendable on the fold line 29, While

top flaps

21 and 22 are bendable on 'the 'fold lines 30., 31 and 32.

Referring to Figs. 3 and 4, the insert `cushion member- 35. is also made of conventional double wall corrugated cardboard and is formed from a single sheet vof the cardboard shown in Fig. 4. The central portion vof the material is bent to .form an open ended channel member 36 having a pair of spaced apart

side portions

37 and 38 and a bottom portion 39 which is of a predetertermined depth with relation to the Vcarton 10 and which is lbent along its upper edges 40 to form top pieces' 41 which extend substantially at right angles to the 'sides of the channel.

-The top pieces 41 extend outwardly a predetermined distance and are bent along their outer edges '42 vto eX- tend downwardly to form cushion side faces 43 which Aare of greater depth than the depth of the channel member 36, and are bent inwardly along their lower edges 44 to form the bottoms 45 of the cushion member. 'The bottoms 45 extend vinwardly substantially the same 'distance as the width of the top pieces 41 and are bent upwardly along their inner edges`46 to form upwardly lextending portions 47 which extend along the outer faces of the

side portions

37 and 38 ofthe channel member '36 into contact with the bottoms of the top pieces 41.

The side portion 37 is provided with a pair of spaced

slots

49 and 50 which extend substantially Vfrom the edges 40 of the cushion Amember 35 to the bottom portion 39. The side portion 38 is alsoprovided with a'pair 'of

similar slots

51 and 52. The slot 49 is oppositelydi'sposed and in alignment with the slot 51, while the slot 50 similarly located .in relation to the slot 52. The upwardly extending portions 47 are also provided with slots53, 54, 55` and 56 in alignment with the slots 49, Si), 51 AAand 52, respectively. 'Ihe toppieces 41 are provided with Aopenings :57, 5S, 59 and 60 'in longitudinal alignment with the slots 49, 5i?, 51 and 52, respectively.

The cushion member 35 is formed from a single block of corrugated 'cardboard material and cut to the blank form shown in Fig. 4. The channel member 36 is formed by folding the blank on the longitudinal parallel fold lines 61, the top pieces 41 are formed by folding the blank 'on the

fold lines

40 and 42, and the bottoms 45 are formed by folding the blank on `the

fold lines

44 and 46.

In use, the container is assembled by setting 'up the carton 1() as shown in Fig. l, setting up the cushion member 35 'as shown in Fig. 3, and then inserting the Vcushion member into the carton as shown in Fig. 5. The article to be shipped in. the container is inserted 'into the cushion vmember 35 between the

side portions

37 and 38 land contacting the bottom portion 39. The top flap 21 of the carton is then folded inwardly and downwardly through the openings 57 and 59 'in the top piece 41 of the cushion member kand into 'the spaces provided Vby the slots `49, 51, 53 land `55. The other top `flap y'22 into the spaces provided by the

slots

50, 52, 54 and 56. The top flaps Z1 and 22 in their assembled position will have their portion 24 superposed on the top pieces 41 of the cushion member 35, while their portions 2,3 and 25 will extend at substantially right angles thereto toward the bottom portion 39 of the cushion member and serve as partitioning` means within the container. The distance between the

slots

49 and 50 and between the

slots

51 and 52 is equal to substantially the length of the article to be shipped in the container. The inner ilap member 19 of the inner top Wall member 17 is lthen folded under the outer ap member 20 and the outer top wall member 18 is superposed on the inner top Wall member and secured to the carton.

While I have shown my invention in a preferred form it will be obvious to those skilled in the art that it is not so limited but is susceptible of various modications without departing from the spirit and scope thereof.
