Description

  The present invention relates to an improvement of a returnable box of a tissue paper carton that is generally used as a returnable box.

  Conventionally, a double-sided cardboard is used for a cardboard box for an exterior. There are AB flute, AC flute, AA flute, etc., but the cardboard box used multiple times like a returnable box also has a problem of the strength of the box, and the corrugated box with AB flute structure is often used. Used (see Non-Patent Document 1).

  In addition, when comparing the A flute and the B flute, the B flute has a higher surface strength, so the printability is high. When a box is made of corrugated cardboard of the AB flute, it is common to make the flute with the B flute on the outside. .

  An invention is disclosed in which the piles of the corrugated cardboard box are not collapsed by crushing the overlapping portions of the flaps of the folded corrugated cardboard box, thereby eliminating the irregularities on the corrugated cardboard surface in the folded state (patent) Reference 1).

  When the cardboard box is folded repeatedly after use, it is difficult to fold the folded cardboard box with the A flute that has been widely used inside and the B flute outside. There was a problem. In the collection part of the automated empty returnable box, there was a problem that the returnable box stood up and collapsed well, causing collapse of the cargo.

  In order to achieve the above object, the present inventors have devised a returnable box for a tissue paper carton in which an A flute is arranged outside and a B flute is arranged inside. The present invention provides the following tissue paper cartons.

  [1] A tissue comprising a double-sided cardboard having a first cardboard outside the box and a second cardboard formed with a flute having a height lower than the first cardboard inside the box. Paper carton return box.

  [2] Two sets of opposing wall surfaces connected to each other at a joint portion and provided with two opposing wall surfaces, and flaps at both ends of each of the wall surfaces, and a top surface and a bottom surface formed by the flaps The tissue paper carton return box according to [1], wherein the box is formed by the wall surface part.

  [3] The tissue paper cartons according to [1] or [2], wherein the wall portions are folded and folded so as to be used repeatedly.

  By using a double-sided cardboard with a flute corrugated cardboard with a high step height on the outside and a flute corrugated cardboard with a low step height on the inside, a returnable box can be used. A foldable returnable box is obtained.

  By using a BA flute cardboard box, the cardboard does not stand up after being folded, and even if the returnable boxes are folded and stacked, the cargo will not collapse.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. The present invention is not limited to the following embodiments, and changes, modifications, and improvements can be added without departing from the scope of the invention.

  FIG. 1 is a diagram showing a state in which a tissue paper carton return box 10 is made of double-sided corrugated cardboard of BA flute with A flute on the outside and B flute on the inside, and the inner flap 30 and the outer flap 31 are opened and folded. Because the B flute is inside, it is easy to fold.

  FIG. 2 is a development view of the returnable box 10 for the tissue paper carton. The first wall surface portion 21, the second wall surface portion 22, the third wall surface portion 23, and the fourth wall surface portion 24 are connected, and the fourth wall surface portion 24 includes a joint portion 25 for coupling with the first wall surface portion 21. . Upper and lower surfaces of the first wall surface portion 21 and the third wall surface portion 23 are provided with inner flaps 30 as constituent elements of the bottom surface and the top surface, and the bottom surface and the ceiling surface are disposed above and below the second wall surface portion 22 and the fourth wall surface portion 24. An outer flap 31 is provided as a component of the surface. The structure of the cardboard box is an A-type cardboard, and the first wall surface part 21 to the fourth wall surface part 24 form four sides of the cardboard box, and the inner flap 30 and the outer flap 31 form the bottom surface of the cardboard box and the ceiling. Form a surface.

  FIG. 3 (a) shows a view when the returnable box 10 for the tissue paper carton is used. The inner flap 30 and the outer flap 31 are opened, the tissue paper carton 35 which is a stored item is put into the return box 10 for the tissue paper carton, and the inner flap 30 and the outer flap 31 are closed. FIG. 3B shows a view in which the inner flap 30 and the outer flap 31 are closed. When the cardboard box is used as the passing box 10, the inner flap 30 and the outer flap 31 are not fixed by gluing or the like, and the bottom and top surfaces are bound not to be opened by a binding band or the like, and the outer flap 31 is fixed. To do. The size of the returnable box 10 is (465 × 335 × 180) mm, and the contents are 300 pieces of 35 g tissue paper carton, and the weight is about 10.5 kg. The weight of the return box 10 is 0.8 kg, and the total weight is about 11.3 kg. A returnable box 10 is used to carry the contents repeatedly.

  In FIG. 4, the figure which folded the returnable box 10 is shown. If the returnable box 10 is a BA flute double-sided cardboard box with the B flute on the inside, the returnable box 10 does not rise when folded, and it is neatly folded.

  FIG. 5A is an enlarged view of the fold portion when the cardboard box of AB flute is folded, and FIG. 5B is an enlarged view of the fold portion of the cardboard box of BA flute. In the AB flute cardboard box, the A flute is on the inside and the B flute is on the outside, so the cardboard easily rises in the folded part, whereas in the BA flute cardboard box, the B flute is on the inside and the A flute is Because it is on the outside, the cardboard is unlikely to rise at the folded portion. That is, when the returnable box 10 for the tissue paper carton of the present invention is used, when the returnable box 10 is folded after use, it is neatly folded and the cardboard rises and does not become bulky. Moreover, since the returnable box 10 is not bulky even in an automated system, the work can be smoothly performed without causing collapse.

  The double-faced cardboard structure of the A flute has a step height of 4.5 to 4.8 mm and a standard number of ridges per 30 cm of 34 ± 2. A flute cardboard is superior in cushioning and has a stronger compressive strength than the B flute, so 90% of the exterior cardboard boxes are made of A flute cardboard.

  The double-faced cardboard structure of the B flute has a step height of 2.5 to 2.8 mm and a standard number of ridges per 30 cm of 50 ± 2. B flute corrugated cardboard is suitable for packaging hard bottles, cans, etc., because the flat pressure is strong.

  The double-sided corrugated cardboard of the AB flute has a structure in which the double-sided cardboard of the A flute and the double-faced cardboard of the B flute are bonded together. When used as an exterior corrugated cardboard, the B flute side has a strong flat pressure and is suitable for printing. Therefore, a cardboard box is often made with the B flute side outside and the A flute side inside. Although the explanation is given in the corrugated boxes of A flute and B flute, the tissue paper carton return box 10 of the present invention is not limited to the double-sided corrugated cardboard box of BA flute. If the double-sided cardboard box has the first corrugated cardboard outside and the flute lower corrugated cardboard inside the cardboard box, the cardboard box can be easily folded after use, and the object of the present invention is achieved.

  A flute with a step height of 4.5 to 4.8 mm and a standard number of ridges per 30 cm of 34 ± 2, and a standard height of steps of 2.5 to 2.8 mm and a standard number of ridges per 30 cm A double-sided corrugated cardboard is produced from a B flute having an A of 50 ± 2, and a corrugated cardboard box is produced such that the A flute is on the outside and the B flute is on the inside. In this case, the height of the step is low and the surface having a large number of ridges is on the inner side, and it becomes easier to bend when folding the cardboard.

  The types of corrugated board are A flute, B flute, C flute (height of step: 3.5 to 3.8 mm, standard number of ridges: 40 ± 2), E flute (height of step: 1 .20mm, standard number of peaks: 93), F flute (step height: 0.75mm, standard number of peaks: 125), G flute (step height: 0.55mm, standard number of peaks: 167), etc. The flute cardboard to be used may be appropriately selected according to the purpose of use.

  A combination of A flute and B flute is usually used for cardboard boxes that are used many times like the returnable box 10, and the A flute is suitable for printing because the surface of the corrugated cardboard is clean and suitable for printing. It was common to use the B flute on the inside and the B flute on the outside.

  This time, we showed a cardboard box with the A flute on the outside and the B flute on the inside as the returnable box 10, but even if it is not the returnable box 10, if you need a cardboard box that folds neatly after using the cardboard box, A corrugated cardboard having a high step height and a small number of standard ridges may be the outside, and a corrugated cardboard having a low step height and a large number of standard ridges may be the inside. For example, in order to make a double-sided corrugated cardboard of E flute and F flute and make it easy to fold, the E flute should be on the inside and the F flute on the outside.

  By setting the A flute on the outside and the B flute on the inside, the cardboard can be easily creased. When the returnable box 10 is made with this cardboard box, the first use is started when collecting the empty returnable box 10 after use. The problem of collapse of goods due to being easily folded and bulky is eliminated.

  When the collection of the empty returnable box 10 is automated, the conventional returnable box has a problem that the cardboard box rises up without being neatly folded, becomes bulky, and collapses. By using the returnable box 10 of the carton, the empty returnable box 10 is neatly folded and flattened, so that it is not bulky and is smoothly recovered on the recovery conveyance line.

  Since the empty returnable box 10 can be collected in a flat shape, it is possible to make the conveyance line of the automation equipment compact, not only improving the recovery efficiency of the returnable box 10 after use, but also the smoothness of the automation line. Work is possible and work efficiency can be improved. Further, the operation efficiency of the recovery device can be improved from 50-60% to 80-90%.

  After the return box 10 is used, the outer flap 31 and the inner flap 30 on the bottom surface and the top surface are opened, formed into a cylindrical shape, folded, and reused as the return box 10.

  The number of repeated use of the returnable box 10 of the present invention is improved to about 20 to 30 times compared to the conventional 15 times, and there is no weakening of the corrugated cardboard by having the A flute on the outside and the B flute on the inside.

  By using the tissue paper carton return box 10 of the present invention, the corrugated cardboard, which was previously bulky when the empty return box 10 was folded, can be folded up neatly without being bulky. In the process of automatically collecting, folding, and stacking the returnable box 10, the collapse of the returnable box 10 is prevented and the automation system can be smoothly operated.
