Abstract

A mattress package may include a plurality of core rolls, a covering roll, and a box containing the plurality of core rolls and the covering roll. The plurality of core rolls may be defined by a plurality of rolled up core segments. The covering roll may be defined by a rolled up cover material configured to cover a mattress core formed via assembling the plurality of core segments.

Claims (48)

1. A mattress package, comprising:

a plurality of core rolls defined by a plurality of rolled up core segments;

a covering roll defined by a rolled up cover material configured to cover a mattress core formed via assembling the plurality of core segments; and

a box containing the plurality of core rolls and the covering roll.

2. The mattress package according to claim 1 , wherein;

the plurality of core rolls and the covering roll are arrangeable in parallel in the box; and

the plurality of core rolls are substantially the same in length.

3. The mattress package according to claim 1 , wherein:

the plurality of core rolls each have a length; and

a sum of the lengths of the plurality of core rolls is equal to at least one of a length of the mattress core and a width of the mattress core.

4. The mattress package according to claim 1 , wherein a length of the covering roll is substantially the same as a length of each core roll of the plurality of core rolls.

5. The mattress package according to claim 1 , wherein the plurality of core rolls includes from two to six core rolls.

6. The mattress package according to claim 1 , wherein the box is a cardboard box.

7. The mattress package according to claim 1 , wherein each core segment of the plurality of core segments includes a plurality of core subsegments arranged in a row along an unrolling direction of the respective core segment.

8. The mattress package according to claim 7 , wherein the plurality of core subsegments are pieces in the form of spring cores.

9. The mattress package according to claim 7 , wherein the plurality of core subsegments are one of (i) the same in size and (ii) different in size.

10. The mattress package according to claim 9 , wherein:

each core subsegment of the plurality of core subsegments is selected from a first base module and a second base module;

the first base module and the second base modules are the same in length but different in width ranging from 50 cm to 100 cm; and

at least one of:

the plurality of core segments each include three base modules or less;

the plurality of core segments each include one first base module and one second base module;

the base modules of a core segment of the plurality of core segments are arranged in one of (i) a same sequence and (ii) a different sequence as the base modules of at least one other core segment of the plurality of core segments; and

the plurality of core segments includes a middle core segment, a first end core segment, and a second end core segment that define a middle section, a first end section, and a second end section of the mattress core, respectively, the base modules of the middle core segment arranged in a sequence different from the base modules of the first end core segment and the base modules of the second end core segment.

11. The mattress package according to claim 1 , wherein the cover material includes:

a mattress cover for wrapping around the mattress core; and

a functional pad for covering the mattress core.

12. The mattress package according to claim 11 , wherein the mattress cover includes a plurality of elastic strips for holding the mattress core at a plurality of corners of the mattress core.

13. A method for packaging a mattress, the mattress including (i) a plurality of core segments arranged side-by-side in one of a lengthwise direction and a widthwise direction of the mattress and (ii) a cover material provided for covering a mattress core formed via assembling the plurality of core segments, the method comprising:

rolling up the plurality of core segments respectively along the other-direction of the lengthwise direction and the widthwise directions to form a plurality of core rolls;

folding and rolling up the cover material into a covering roll; and

putting the plurality of core rolls and the covering roll into a box.

14. The method according to claim 13 , wherein the plurality of core rolls includes from two to six core rolls.

15. The method according to claim 14 , wherein the plurality of core segments includes a plurality of spring core segments.

16. The method according to claim 13 , further comprising compressing each core segment of the plurality of core segments in a thickness direction of the respective core segment before rolling up the respective core segment.

17. The method according to claim 16 , wherein;

the plurality of core segments each include a plurality of core subsegments; and

the method further comprises, before compressing a respective core segment of the plurality of core segments, packing the plurality of core subsegments of the respective core segment into a bag with the plurality of core subsegments arranged in a row along a rolling direction of the respective core segments.

18. The method according to claim 17 , wherein:

each core subsegment of the plurality of core subsegments is selected from a first base module and a second base module;

the first base module and the second base modules are the same in length but different in width ranging from 50 cm to 100 cm; and

at least one of:

the plurality of core segments each include three base modules or less;

the plurality of core segments each include one first base module and one second base module;

the method further comprises arranging the base modules of a core segment of the plurality of core segments in one of (i) a same sequence and (ii) a different sequence as the base modules of at least one other core segment of the plurality of core segments; and

the method further comprises arranging the base modules of a middle core segment of the plurality of core segments in a sequence different from the base modules of a first end core segment of the plurality of core segments and the base modules of a second end core segment of the plurality of core segments, and the middle core segment, the first end core segment, and the second end core segment define a middle section, a first end section, and a second end section of the mattress core, respectively.

19. The method according to claim 13 , wherein folding and rolling up the cover material includes folding the cover material into a substantially same size and shape as one core segment of the plurality of core segments and then rolling up the folded cover material along a same direction as the plurality of core segments.

20. The method according to claim 13 , wherein the box is a cardboard box.
