  In recent years, with the heyday of Internet shopping, due to a logistics crisis due to a shortage of labor, home delivery charges have been raised one after another, and further downsizing of mattress packaging is required. Further, in the mattress package, there is a concern that the mattress may be restored when a hole is opened in the bag and the vacuum is broken.

  Therefore, in the present invention, as a means for solving the above problems, the roll-shaped mattress and a cardboard box in which the roll-shaped mattress is accommodated are formed. The roll-shaped mattress is composed of a pocket coil mattress, a bag, and a film. Is provided with a pocket coil assembly in which a plurality of coil springs are arranged in parallel, and the pocket coil assembly is continuously formed along the longitudinal direction of the pocket coil mattress by a belt-like sheet material having air permeability. A continuous pocket coil spring array formed in a row by accommodating one coil spring in one bag of a plurality of continuous cylindrical bags is arranged in a plurality of rows in the width direction of the pocket coil mattress. The pocket coil mattress is compressed and contained in the bag in a sealed manner In this state, the pocket coil mattress is folded in two vertically between the two innermost adjacent pocket coil spring rows in the width direction of the pocket coil mattress, and the folded pocket coil mattress is placed on the film. In a rolled state together with the film, and a roll structure in which only the film is wound a plurality of times on the outside of the roll-shaped pocket coil mattress from the end of the roll-shaped pocket coil mattress. A mattress packaging body is provided.

  Temporary pocket coil mattress (comprising a pocket coil assembly in which a plurality of coil springs are arranged in parallel, and the pocket coil assembly is continuously formed along the longitudinal direction of the pocket coil mattress by a belt-like sheet material having air permeability. A pocket coil mattress in which a row of continuous pocket coil springs arranged in a plurality of rows in the width direction of the pocket coil mattress is accommodated in one bag of a plurality of continuous cylindrical bags. If the roll mattress is wound as it is in a state of being compressed and accommodated in a sealed state, the length of the roll mattress in the axial direction is equal to or greater than the width of the original pocket coil mattress, and accordingly, the roll mattress along the axial direction of the roll mattress The length of one side of the cardboard box is also greater than the width of the original pocket coil mattress. On the other hand, according to the present invention, a pocket coil mattress (including a pocket coil assembly in which a plurality of coil springs are arranged in a parallel arrangement is formed. A plurality of continuous pocket coil spring rows formed in a row by accommodating one coil spring in a bag of a plurality of continuous cylindrical bags formed continuously along the direction in the width direction of the pocket coil mattress. The pocket coil mattresses arranged side by side are folded in two vertically between two adjacent innermost continuous pocket coil spring rows in the width direction of the pocket coil mattress in a state where the pocket coil mattress is compressed and accommodated in a bag. Since the folded pocket coil mattress is wound into a roll, the axial direction of the roll mattress Length will be less than the width of the original Pokettokoirumattoresu can also be less than the width of the original Pokettokoirumattoresu in with the length of one side of the cardboard box along the axial direction of the rolled mattress it.

  In addition, the folded pocket coil mattress is not rolled as it is, but is wound together with the film in a state of being placed on the film, and the rolled pocket coil mattress is wound. Since only the film from the end is wound a plurality of times outside the roll-shaped pocket coil mattress, the form of the roll-shaped mattress can be maintained even if a hole is opened in the bag and the vacuum is broken.

In a state of being compressed and accommodated in a bag, the pocket coil mattress is folded in two vertically between the two adjacent innermost continuous pocket coil spring rows in the width direction of the pocket coil mattress, and the folded pocket coil mattress is rolled. Is wound into a pocket, so that a pocket coil mattress (multiple coil The pocket coil assembly includes a plurality of continuous cylindrical bags formed continuously along the longitudinal direction of the pocket coil mattress by a belt-like sheet material having air permeability. A pocket coil mattress in which a row of continuous pocket coil springs arranged in a row by accommodating one coil spring in a bag is arranged in a plurality of rows in the width direction of the pocket coil mattress is compressed and accommodated in a bag. Compared to the case where the roll mattress is wound as it is in the state, the diameter of the roll mattress becomes longer, and accordingly, the length of the remaining two sides of the corrugated cardboard box orthogonal to the axial direction of the roll mattress is also increased. When the pocket coil mattress is wound on a roll with the film placed on the film, By applying tension to the film, the diameter of the roll mattress is shortened compared to the case where the folded pocket coil mattress is rolled up as it is, and accordingly the corrugated cardboard box perpendicular to the axial direction of the roll mattress The length of the remaining two sides can be shortened.

  Thus, a pocket coil mattress (including a pocket coil assembly in which a plurality of coil springs are arranged in a parallel arrangement is continuously formed along the longitudinal direction of the pocket coil mattress by a belt-like sheet material having air permeability. (Pocket coil mattress in which one coil spring is accommodated in one of a plurality of formed continuous cylindrical bags and a row of continuous pocket coil springs arranged in a row is arranged in a plurality of rows in the width direction of the pocket coil mattress) Is folded in two vertically from between two adjacent innermost continuous pocket coil spring rows in the width direction of the pocket coil mattress in a state in which the bag is hermetically compressed and accommodated in a bag. Corrugated board along the axial direction of the roll mattress by being rolled up The length, width, and width of the mattress package are not offset by the reduction in the length of one side of the box and the length of the remaining two sides of the corrugated box perpendicular to the axial direction of the roll mattress. The total of the three sides of the height can be reduced efficiently, that is, the mattress package can be made more compact and the postage (courier service fee) of the product (pocket coil mattress) can be reduced. Can be delivered to customers even cheaper.

The bag 5 is made of an airtight synthetic resin bag made of polyethylene film or the like. The film 6 is made of a strip-shaped synthetic resin film made of a polyethylene film or the like, and has a width that is approximately half the width of the pocket coil mattress 4.

  And the roll-shaped mattress 2 is formed in the following procedures.

  First, as shown in FIG. 9A, the pocket coil mattress 4 is put in the bag 5.

  Next, as shown in FIG. 9 (b), the pocket coil mattress 4 placed in the bag 5 was pushed into the bag 5 from above by using the presser plate at the lower end of the plunger of the press machine. The pocket coil mattress 4 is compressed together with the bag 5 in the thickness direction, and air (the air inside the bag 5 and the air contained in the pocket coil mattress 4) is forcibly discharged from the inside of the bag 5, and this compression is performed. It seals by welding the opening part 5a of the bag 5 in the state. Then, the bag 5 is sealed, and the internal pocket coil mattress 4 is not restored while maintaining the compressed state in the thickness direction.

  Next, as shown in FIG. 9 (c), the pocket coil mattress 4 compressed and accommodated in the bag 5 in a sealed manner is connected to the two innermost adjacent continuous pocket coil spring rows 23a and 23b in the width direction. It is folded vertically along the longitudinal direction of the pocket coil mattress 4 from the middle, and is placed on the film 6 in this folded state.

  Next, as shown in FIG. 9 (d), the pocket coil mattress 4 placed in a folded state on the film 6 is rolled together with the film 6. When the pocket coil mattress 4 placed in a folded state on the film 6 is rolled together with the film 6, the outer periphery of the winding shaft of the winder (corrugated cardboard formed by previously rounding the cardboard) The film 6 alone is wound a plurality of times, and then the pocket coil mattress 4 is wound into a roll together with the film 6 while applying tension to the film 6. When the winding of the pocket coil mattress 4 is finished, the film 6 is wound around the outer side a plurality of times, and then the film 6 is cut in the width direction to form the roll-shaped mattress 2.

  Finally, as shown in FIG. 9 (e), the single-sided adhesive tape 7 is spirally wound around the outer periphery of the roll-shaped mattress 2 so that the end of winding of the film 6 is fixed to the underlying film 6 so as not to be loosened. Then, after the roll mattress 2 is maintained and not released, the roll mattress 2 is pulled out from the winding shaft of the winder together with the corrugated cardboard cylinder, and then the roll mattress 2 is removed. The cardboard tube is pulled out to form the roll mattress 2.

  The roll-shaped mattress 2 formed in this way is put in a cardboard box 3 to form the mattress packing body 1 shown in FIGS.

  As is apparent from the above, the mattress packing body 1 according to the present embodiment includes a roll mattress 2 and a cardboard box 3 in which the roll mattress 2 is accommodated. The roll mattress 2 includes a pocket coil mattress 4 and a bag. 5 and film 6, and the pocket coil mattress 4 includes a pocket coil assembly 21 in which a plurality of coil springs 20 are arranged in a parallel arrangement. The pocket coil assembly 21 is formed of a breathable belt-like sheet material. A continuous pocket coil spring array 23 formed in a row by accommodating one coil spring 20 in one bag of a plurality of continuous cylindrical bags 22 formed continuously along the longitudinal direction of the pocket coil mattress 4 and arranged in a plurality of rows in the width direction. In a state where the loess 4 is compressed and accommodated in the bag 5, the pocket 4 is folded in two vertically between the two adjacent innermost continuous pocket coil spring rows 23 a and 23 b in the width direction of the pocket coil mattress 4. The folded pocket coil mattress 2 is placed on the film 6 and rolled together with the film 6, and only the film 6 is rolled from the end of the roll of the pocket coil mattress 4. This has a roll structure that is wound a plurality of times on the outside of the pocket coil mattress 4.

  Then, if the pocket coil mattress 4 is wound in the form of a roll while being compressed and accommodated in the bag 5, the length of the roll mattress 2 in the axial direction is equal to or greater than the width of the original pocket coil mattress 4. Accordingly, the length A of one side of the cardboard box 3 along the axial direction of the roll-shaped mattress 2 is also equal to or larger than the width a of the original pocket coil mattress 4. On the other hand, according to the mattress packing body 1 of the present embodiment, the two adjacent rows in the innermost side in the width direction of the pocket coil mattress 4 in a state where the pocket coil mattress 4 is compressed and accommodated in the bag 5 in a sealed manner. The pocket coil mattress 2 is folded in two vertically from between the pocket coil spring rows 23a and 23b, and the folded pocket coil mattress 2 is wound into a roll shape. Therefore, the axial length of the roll mattress 2 is the original pocket coil mattress 6 Accordingly, the length A of one side of the cardboard box 6 along the axial direction of the roll mattress 2 can be made substantially half of the width of the original pocket coil mattress 4.

  Further, the folded pocket coil mattress 4 is not wound in a roll shape as it is, but is wound in a roll shape together with the film 6 while being placed on the film 6, and the roll-shaped pocket coil. Since only the film 6 is wound outside the roll-shaped pocket coil mattress 4 a plurality of times from the end of winding of the mattress 4, even if the hole is opened in the bag 5 and the vacuum is broken, the form of the roll-shaped mattress 2 Can be maintained.

  Then, the pocket coil mattress 4 is folded in two vertically between the two adjacent innermost continuous pocket coil spring rows 23a and 23b in the width direction of the pocket coil mattress 4 in a state where the pocket coil mattress 4 is compressed and accommodated in the bag 5. When the pocket coil mattress 4 folded in half is wound into a roll shape, the pocket coil mattress 4 is rolled in a roll shape as it is in a state of being compressed and accommodated in a bag 5 in a sealed manner. As the diameter of the mattress 2 becomes longer, the lengths B and C of the remaining two sides of the cardboard box 3 perpendicular to the axial direction of the roll mattress 2 become longer. When the film 6 is wound into a roll with the film 6 placed on the film, a tension is applied to the film 6 to Compared with the case where the folded pocket coil mattress 4 is wound in the form of a roll as it is, the diameter of the roll mattress 2 is shortened, and accordingly, the length of the remaining two sides of the corrugated cardboard box 3 perpendicular to the axial direction of the roll mattress 2 B and C can also be shortened.

  As a result, the pocket coil mattress 4 is compressed and accommodated in the bag 5 in a hermetically sealed manner, and the pocket coil mattress 4 in the widthwise direction of the pocket coil mattress 4 is inserted vertically between the two adjacent continuous pocket coil spring rows 23a and 23b. When the folded pocket coil mattress 4 is wound into a roll shape, the length A of one side of the cardboard box 3 along the axial direction of the roll mattress 2 is shortened, and the roll mattress 2 The length, width, and height of the mattress package 1 are efficiently reduced without canceling out the lengths B and C of the remaining two sides of the corrugated cardboard box 3 that are orthogonal to the axial direction. In other words, the mattress package 1 can be made more compact and the shipping cost of the product (pocket coil mattress 4) (courier service charge) Becomes cheaper, it is possible to deliver even more cheaper your products.

  Specifically, for example, a pocket coil having S (single) size of about 97 cm wide × 195 cm long × 15 cm to 20 cm thick and 465 coil springs 20 arranged in parallel (15 columns × 31 rows). In the case of the pocket coil mattress 4 provided with the aggregate 21, when the mattress package 1 is used, the length A of one side of the cardboard box 3 along the axial direction of the roll mattress 2 is 57 cm (the length of the roll mattress 2 in the axial direction). 65cm), the length of the remaining two sides of the corrugated cardboard box 3 perpendicular to the axial direction of the roll mattress 2 is 40cm (the diameter of the roll mattress 2 is 38cm), and the three sides of the length, width and height A total packing size of about 137 cm can be realized.

  A pocket having a pocket coil assembly 21 of 589 coil springs 20 arranged in a parallel arrangement (19 columns × 31 rows) in an SD (semi-double) size of 120 cm wide × 195 cm long × 15 cm to 20 cm thick. In the case of the coil mattress 4 (the illustrated example), when the mattress package 1 is used, the length A of one side of the cardboard box 3 along the axial direction of the roll mattress 2 is 67 cm (the axial length of the roll mattress 2). 65cm), the length of the remaining two sides of the corrugated cardboard box 3 perpendicular to the axial direction of the roll mattress 2 is 40cm (the diameter of the roll mattress 2 is 38cm), and the three sides of the length, width and height A total package size of about 147 cm can be realized.

  Furthermore, a pocket provided with a pocket coil assembly 21 having a D (double) size of 140 cm wide × 195 cm long × 15 cm to 20 cm thick and 682 coil springs 20 arranged in a parallel arrangement (22 columns × 31 rows). In the case of the coil mattress 4 (the illustrated example), when the mattress package 1 is used, the length A of one side of the cardboard box 3 along the axial direction of the roll mattress 2 is 77 cm (the axial length of the roll mattress 2). 70cm), the length of the remaining two sides of the corrugated cardboard box 3 orthogonal to the axial direction of the roll mattress 2 is 40cm (the diameter of the roll mattress 2 is 38cm), and the three sides of the length, width and height A total package size of about 157 cm can be realized.

  In this way, the pocket coil mattress 4 in which a plurality of coil springs 20 are arranged in parallel is compressed in the thickness direction, and vertically between the innermost adjacent two consecutive pocket coil spring rows 23a and 23b. Folding in half and then winding the film 6 together with the film 6 in a roll shape, the packing size of SD and D sizes is 160 cm or less in total on three sides. The postage (courier service fee) of the mattress 4) is reduced, and the product can be delivered to the customer at a lower price.
