Abstract

A suspension box member for use as a base or platform of a shipping container is disclosed. The suspension box is made of fiberboard or other material which deflects to absorb shock and other forces which would otherwise be transmitted directly to the item being shipped. The suspension box is of relatively simple design, thus making it easily adaptable for use with various types of covers for the shipping container. Such covers may be in the form of a box with an open bottom, a slotted telescope cover for rectangular items or various form-fit covers, the latter being particularly suitable for upholstered chairs.

Claims

1. A shipping container for articles of furniture and the like, comprising

a. an integral hollow suspension box base unit for supporting the article, said suspension box base unit consisting of horizontal rectangular top and bottom walls and four vertical side walls, said top and bottom walls being spaced to define an open unobstructed chamber extending between said four vertical side walls;

b. a cover consisting of horizontal top and vertical side walls, said cover being open at its bottom thereby to permit said cover to be fitted downwardly over the article to a closed position in which the cover top wall is spaced from the top wall of said suspension box base unit, thereby to enclose the article of furniture, and the lower edge portions of said cover are adjacent the outer surface of the vertical side walls of said base unit; and

c. means connecting the lower edge portions of said cover with the vertical side walls of said base unit;

d. at least the top wall of said base unit being imperforate and formed of a material which deflects under load, thereby to cushion the article against shock forces applied to said container.

2. A shipping container as defined in claim 1, wherein said base unit is formed of fiberboard.

3. A shipping container as defined in claim 1, wherein said base unit is formed of a side-opening container in which two of the side walls are formed by flaps attached to the remaining side walls and the top and bottom walls.

4. The shipping container of claim 3 wherein the length of each of the flaps is equal to the height of the vertical side walls.

5. The shipping container of claim 3 wherein the length of each of the flaps is equal to one-half the height of the vertical side walls.

6. The shipping container of claim 3 wherein the length of each of the flaps is greater than one-half the height of the vertical side walls but less than the height of the vertical side walls.

7. The shipping container of claim 4 wherein a tape joint is provided both in the top wall and in the flaps attached to the top wall.

8. The shipping container of claim 4 wherein a stitched or glued joint is provided both in the top wall and in the flaps attached to the top wall, and with an overlap being provided in the portions of the top wall and flaps being joined.

9. The container of claim 1, wherein the cover is in the form of a box having one open end which fits over the base unit.

10. The container of claim 1, wherein the cover is in the form of an open tube having four side walls and wherein two base units are employed, one at each end of the cover.

11. The container of claim 1, wherein there is included within the base unit a compartment for carrying a component being shipped.

12. The container of claim 1, wherein the item of furniture is attached to the base unit by a shrink-wrap material.

13. The container of claim 1, wherein the cover is in the form of an L-shaped box having an open end which fits over the base unit.

14. The container of claim 13 wherein the cover is formed of first and second blank portions, the first blank portion having score lines which define a back wall and two L-shaped side walls, and wherein the first blank portion is provided with flaps which, when folded inwardly, extend completely around the inner periphery of the upper edge of the first blank portion in the assembled configuration, the second blank portion being provided with three score lines in parallel relationship, the middle score line of which has a reverse score, the second blank portion being folded on the three score lines to define the top wall and upper and lower front walls of the cover, and with the side walls of the first blank portion being connected to the lower front wall of the second blank portion by a pair of tape joints.

15. The container of claim 13 wherein the cover is formed of first and second blank portions, the first blank portion having score lines which define a back wall, two L-shaped side walls and a front wall, and wherein the first blank portion is provided with flaps which, when folded inwardly in the assembled configuration, extend around the inner periphery of the first blank portion immediately adjacent the upper edges of the front wall and that segment of each L-shaped side wall which is of the same height as the front wall, the second blank portion being provided with score lines which define a back wall, two side walls and a front wall, together with flaps attached to the upper and lower edges of each of said four walls of the second blank portion, the flaps attached to the upper edges of each of said four walls folding together in overlapping relationship to define a top wall, the flaps attached to the lower edges of the back wall and side walls of the second blank portion extending downwardly for attachment along the sides and back wall of the first blank portion, and the flap attached to the lower edge of the front wall of the second blank portion extending horizontally outward so that its outer edge is in sealing engagement with the outer edge of the flap attached to the upper edge of the front wall of the first blank portion, with the result that the container is completely sealed.

16. The container of claim 15 wherein tab means is employed to connect the opposite ends of each blank portion.

17. The container of claim 13 wherein the cover is formed of a blank having score lines which define a back wall, two L-shaped side walls and a front wall, a flap attached to the upper edge of the back wall to define a top wall for the higher segment of the L-shaped configuration, inwardly folded flaps attached to the upper edges of the side walls to extend along the entire inner periphery of the side walls in the assembled configuration, the flaps attached to the horizontal edge of the higher and lower segments of the side walls being of a length at least equal to one-half the width of the front and back walls, the flap attached to the back wall being provided with a flap which folds downwardly to overlap the flap attached to the vertical edge of the higher segment of the L-shaped configuration, and a flap attached to the upper edge of the front wall, said front wall flap having a reverse score line and being of a size sufficient to cover the top portion of the lower segment of the L-shaped configuration and the front portion of the higher segment of the L-shaped configuration, so that the outer edge of the front wall flap is in sealing engagement with the outer edge of the flap attached to the upper edge of the back wall.

18. The container of claim 17 wherein tab means is employed to connect the opposite ends of the blank.

19. The container of claim 13 wherein the cover is formed of first and second blank portions, the first blank portion having score lines which define a back wall, two L-shaped side walls and a front wall, and wherein the first blank portion is provided with flaps which, when folded inwardly, extend completely around the inner periphery of the upper edge of the first blank portion in the assembled configuration, the second blank portion being provided with a score line and a reverse score line which define a one-piece top wall for the L-shaped cover.

20. The container of claim 19 wherein tab means is employed to connect the opposite ends of the first blank portion.

21. The container of claim 1, wherein said cover is connected to fully cover the sides of the base unit.

22. The container of claim 1, wherein said cover is connected to only partially cover the sides of the base unit.
