DETAILED DESCRIPTION OF THE INVENTION

[0013] In the present invention, the objective of providing a connecting box body for forming a box body unit by connecting two box bodies, in which the process of adhering the connecting part to the box body to be connected and the process of fixing the top cover in a closed state can be performed in a single operation, is achieved as follows.

[0014] A box body (connecting box body) 1 according to the present invention has a box body 3 and a protruding portion 110 protruding from the box body 3. The box body 1 is a connecting box body, and a box body unit U (see FIG. 7) is formed by connecting two box bodies 1 together.

[0015] The box 1 is formed entirely from a single sheet-like blank (specifically, a blank made of cardboard or other paper). In other words, the box 1 is a box made of paper such as cardboard (particularly, thin double-sided cardboard).

[0016] The box body 3 has a peripheral portion 5, a bottom portion 50 connected to the lower side of the peripheral portion 5, and a lid portion 100 and flap portions 106, 108 connected to the upper side of the peripheral portion 5.

[0017] Here, the peripheral surface portion 5 is generally sleeve-shaped and has a front surface portion 10, a right side surface portion 20 connected to the right side of the front surface portion 10 via fold line C4, a left side surface portion 30 connected to the left side of the front surface portion 10 via fold line C3, a back surface portion 40 connected to the rear side of the left side surface portion 30 via fold line C2, and an adhesive tab 45 connected to the right side of the back surface portion 40 via fold line C1. The adhesive tab 45 is adhered to the inner surface of the end region on the back side of the right side surface portion 20. The fold lines C1, C2, C3, and C4 are parallel to one another, and when the peripheral surface portion 5 is unfolded, the front surface portion 10 and the back surface portion 40 are parallel to one another, the right side surface portion 20 and the left side surface portion 30 are parallel to one another, and adjacent surfaces of the peripheral surface portion 5 form right angles to one another. The right side surface 20, the left side surface 30 and the back surface 40 are all rectangular, and the front surface 10 has a semicircular cutout 12 formed at the top end of the rectangular shape.

[0018] The bottom surface 50 is a so-called one-touch bottom, and has a first arm 60, a second arm 70, a third arm 80, and a fourth arm 90, and when the box body 3 is assembled, it has an approximately rectangular outer shape as shown in Figure 3.

[0019] Here, first arm 60 is connected to the lower side of left side surface 30 via a fold line and is formed in a generally trapezoidal shape that narrows toward the tip, with part of its upper surface forming part of the inner bottom surface of box main body 3. This first arm 60 is formed point-symmetrically with fourth arm 90 with respect to the center of bottom surface 50 when bottom surface 50 is assembled.

[0020] The second arm 70 is connected to the lower edge of the front face 10 via a fold line and is formed in a generally rectangular shape, with part of the upper surface of the second arm 70 forming part of the inner bottom surface of the box body 3. A fold line 70-1 (the fold line 70-1 has a mountain fold on the upper surface) is formed from a corner of the second arm 70 (the lower end of the boundary between the front face 10 and the right side face 20) diagonally relative to the edge that forms the boundary between the second arm 70 and the front face 10. The fold line 70-1 divides the second arm 70 into a main body 72 and a tip end 74. A notch 72a is formed on the tip of the main body 72 near the tip end 74 so as to engage with the other main body 82. The upper surface of the tip end 74 is bonded to the lower surface of the fourth arm 90.

[0021] The third arm 80 is connected to the lower edge of the rear portion 40 via a fold line and is formed point-symmetrically with the second arm 70 when the bottom portion 50 is assembled. That is, the third arm 80 is connected to the lower end of the rear portion 40 via a fold line and is formed in a substantially rectangular shape, with a portion of the upper surface of the third arm 80 forming a portion of the inner bottom surface of the box body 3. A fold line 80-1 (the fold line 80-1 has a mountain fold on the upper surface) is formed from a corner of the third arm 80 (the lower end of the boundary between the left side portion 30 and the rear portion 40) diagonally relative to the side that forms the boundary between the third arm 80 and the rear portion 40. The fold line 80-1 divides the third arm 80 into a main body portion 82 and a tip portion 84. A notch 82a is formed on the tip of the main body portion 82 toward the tip portion 84 so as to engage with the other main body portion 72. The upper surface of the tip portion 84 is bonded to the lower surface of the first piece portion 60 .

[0022] In addition, the fourth arm 90 is connected to the lower end of the right side portion 20 via a fold line and is formed into an approximately trapezoidal shape that becomes narrower as it approaches the tip, and part of its upper surface forms part of the inner bottom surface of the box main body 3.

[0023] In addition, since the length in the left-right direction of the box main body 3 is longer than the length in the front-to-back direction, the second arm 70 and the third arm 80 are connected to the front face 10 and the back face 40, but if the length in the left-to-right direction is shorter than the length in the front-to-back direction, the second arm 70 and the third arm 80 may be connected to the right side face 20 and the left side face 30.

[0024] The lid 100 has a lid main body 102 connected to the upper side of the back surface 40 via a fold line, and an insertion piece 104 connected to the tip of the lid main body 102 via a fold line. The lid 100 covers the upper opening of the peripheral surface 5, and the lid main body 102 mainly covers the upper opening of the peripheral surface 5.

[0025] In addition, the flap portion 106 is connected to the upper edge of the right side portion 20 via a fold line and has an approximately trapezoidal shape, and the flap portion 108 is connected to the upper edge of the left side portion 30 via a fold line and has an approximately trapezoidal shape.

[0026] The peripheral part 5 is spread to assemble the box body 3, and the flaps 106 and 108 are folded inward, and the insertion piece 104 is inserted into contact with the inside of the front part 10, thereby closing the lid part 100.

[0027] Next, the protrusion 110 is connected to the edge on the rear side of the right side surface portion 20 via a cut line K1. The protrusion 110 has a zipper portion 120 connected to the edge on the rear side of the right side surface portion 20 via the cut line K1, a side surface adhesive portion 130 connected to the zipper portion 120 via a cut line K2, and an upper surface adhesive portion 140 connected to the upper end (upper edge) of the side surface adhesive portion 130 via a fold line C6. A cut line K3 is formed along the fold line C6. In other words, the protrusion 110 is formed to protrude toward the rear side from the right side surface portion 20, which serves as a first side surface portion, which is one of the right side surface portion and the left side surface portion.

[0028] The zipper section 120 is a strip-shaped region sandwiched between cut lines K1 and K2, where cut line K1 is formed by arranging multiple linear cuts and multiple generally V-shaped cuts at the upper end parallel to fold line C4, and cut line K2 is formed by arranging multiple linear cuts and multiple generally inverted V-shaped cuts at the upper end at intervals from cut line K1, and cut line K2 meanders in a generally inverted S-shape. The zipper section 120 has a tab portion 122 which is the region between the linear cuts at cut line K1 and the linear cuts at cut line K2, and a zipper body 124 formed downward from tab portion 122 via fold line C5. The zipper portion 120 is designed so that by gripping the tab portion 122 with fingers and pulling it downward, the cut lines K1 and K2 are broken, and the zipper portion 120 can be removed.

[0029] The side adhesive portion 130 has a generally vertically elongated rectangular shape and has a straight side 130a parallel to the fold line C4, a straight side 130b extending from the lower side of the zipper portion 120 and forming a right angle with the side 130a, and a side along the fold line C6. The side adhesive portion 130 is separated from the zipper portion 120 by a cut line K2.

[0030] The top adhesive portion 140 has a substantially square shape, and the cut line K3 between it and the side adhesive portion 130 is formed by arranging a linear cut in a straight line along the boundary between the side adhesive portion 130 and the top adhesive portion 140, and the fold line C6 and the cut line K3 are formed on an extension of the top edge of the front portion 10 when the box 1 is in an unfolded state. In other words, when the lid portion 100 is closed, by folding the top adhesive portion 140 relative to the side adhesive portion 130 via the fold line C6 and the cut line K3, the top adhesive portion 140 comes into contact with the top surface of the lid main body 100 substantially parallel to the top surface of the lid main body 100.

[0031] Double-sided adhesive tape 150 is adhered to the regions of side surface adhesive portion 130 and top surface adhesive portion 140. In other words, double-sided adhesive tape 150 is provided on the inner surface of the attachment region, which is the region from side surface adhesive portion 130 to top surface adhesive portion 140 (the surface opposite to the surface on the same side as the outer surface of right side surface portion 20), and double-sided adhesive tape 150 is formed from a single double-sided adhesive tape from side surface adhesive portion 130 to top surface adhesive portion 140. Double-sided adhesive tape 150 has an adhesive portion 152 (see FIGS. 5 and 6 ) adhered to the inner surface of the attachment region and a release paper 154 covering the adhesive portion. By providing double-sided adhesive tape 150, when connecting two boxes 1, the adhesive portion 152 can be exposed by simply peeling off the release paper 154, making it easy to adhere side surface adhesive portion 130 and top surface adhesive portion 140.

[0032] The zipper portion 120, the side adhesive portion 130, and the top adhesive portion 140 of the protrusion 110 are formed on the same plane, and the protrusion 110 has a single plate-like shape as a whole. Furthermore, the protrusion 110 is formed on the same plane as the right side surface portion 20, and the protrusion 110 and the right side surface portion 20 together form a single plate-like shape as a whole.

[0033] That is, the protruding portion 110 is formed to protrude from the peripheral surface portion 5 of the box body 3 toward the rear side.

[0034] It should be noted that the folding lines C1 to C6 and other folding lines have folding lines provided on the inner surfaces.

[0035] A description will now be given of how to use the box body 1 configured as described above. Two boxes 1 can be connected to form one box body unit U.

[0036] That is, the release paper 154 of the double-sided adhesive tape 150 is peeled off for the two boxes 1, and the two boxes 1 are arranged with their back surfaces 40 facing each other as shown in Fig. 5. Thereafter, with the two back surfaces 40 facing each other and in contact with each other, the adhesive portion 152 of each box 1 is adhered to the outer surface of the left side surface 30 (that is, the left side surface 30 becomes the second side surface, which is the other of the right side surface and the left side surface) of the box 1 to be connected (or may be the object to be adhered), as shown in Fig. 6. That is, for the two boxes 1, each side surface adhesive portion 130 is adhered to the left side surface 30 of the box 1 to be connected.

[0037] Next, for each of the two box bodies 1, the top adhesive portion 140 is folded toward the side adhesive portion 130 via the fold line C6, and the top adhesive portion 140 is adhered to the lid body 102 of the box body 1 to be connected via the adhesive portion 152 provided on the back surface of the top adhesive portion 140, resulting in the state shown in Figure 7.

[0038] As a result, the two side adhesive parts 130 are adhered to the left side part 30, thereby connecting the two boxes 1, and the top adhesive part 140 is adhered to the lid main body 102, thereby fixing (i.e., locking) the lid part 100 in the closed state. By connecting the two boxes 1, a box unit U consisting of the two boxes 1 is formed.

[0039] As described above, when bonding the side adhesive portion 130 and the top adhesive portion 140, it is sufficient to press the side adhesive portion 130 from the outside to bond it to the left side surface portion 30, and then fold the top adhesive portion 140 and bond it to the lid main body 102, so that the side adhesive portion 130 and the top adhesive portion 140 can be bonded in a single operation. In other words, it is sufficient to press the side adhesive portion 130 upward from the lower end region with a finger, and then fold the top adhesive portion 140 with the finger that pressed it and press it against the lid main body 102, so that the step of bonding the side connection portion 130, which is a connection portion for bonding to the box body 1 to be connected, and the step of fixing the lid 100 in the closed state can be performed in a single operation.

[0040] Next, to separate the box body unit U, which is made up of two connected box bodies 1, into two, the zipper portions 120 of each box body 1 are removed. That is, by grasping the tab portions 122 with fingers and pulling downward, the cutting lines K1 and K2 are broken and the zipper portions 120 are removed, as shown in FIG. 8. To separate the box body unit U, both zipper portions 120 are removed. As a result, the box body 2 can be separated into two box bodies 2, as shown in FIG. 9. This box body 2 is composed of a box main body 3 and a side adhesive portion 130 and a top adhesive portion 140 that are adhered to the box main body 3. Note that in the box body 2, the side adhesive portion 130 and the top adhesive portion 140 of the box body 1 that was the object of connection remain adhered.

[0041] As described above, even when the zipper portion 120 is removed and the box body 2 is separated into two, the top adhesive portion 140 connected to the side adhesive portion 130 is adhered to the lid body 102, so that the lid portion 100 of the box body 2 can be kept fixed in the closed state.

[0042] Furthermore, in each box body 2, to open the lid portion 100, the cut line K3 between the side adhesive portion 130 and the top adhesive portion 140 is broken, thereby releasing the closed state of the lid portion 100, and the lid portion 100 can be opened.

[0043] In the above description, the protrusion 110 is described as protruding from the right end of the box body 3 toward the rear side, but it may also be configured to protrude from the left end of the box body 3 toward the rear side. That is, as shown in FIG. 10 , a box 1′ may be configured to be symmetrical to the box body 1, and the protrusion 110 may be configured to be connected to the left side surface 30. That is, the protrusion 110 is formed to protrude toward the rear side from the left side surface 30, which serves as a first side surface that is one of the right side surface and the left side surface. In that case, the glue tab 45 is connected to the left edge of the rear surface 40 via the fold line C1 and is adhered to the inner surface of the end region on the rear side of the left side surface 30. In the case of this box body 1', to connect two box bodies 1', with the back portions 40 in contact with each other, the side connection portion 130 is adhered to the outer surface of the right side 20 (i.e., the right side portion 20 becomes the second side portion, which is the other of the right side portion and the left side portion) of the box body 1' to be connected, and the top adhesive portion 140 is adhered to the lid body 102.

[0044] In the above description, the cover 100 is connected to the upper edge of the rear surface 40, but it may be connected to the upper edge of the front surface 10. In this case, the semicircular cutout 12 is not formed at the upper end of the front surface 10, but is formed at the upper end of the rear surface 40.

[0045] Furthermore, the lid portion 100 may be connected to the upper edge of the first side surface portion, rather than to the upper edge of the back surface portion 40 or the upper edge of the front surface portion. That is, in the case of the box body 1, the lid portion 100 is connected to the upper edge of the right side surface portion 20, which serves as the first side surface portion, and in the case of the box body 1', the lid portion 100 is connected to the left side surface portion 30, which serves as the first side surface portion. In this case, when the two boxes 1, 1' are connected and the upper surface adhesive portion 140 is adhered to the lid portion 100, the upper surface adhesive portion 140 is adhered to the region of the tip side of the lid portion 100. In this case, the semicircular cutout portion 12 is formed at the upper end of the second side surface portion (the upper end of the left side surface portion 30 in the case of the box body 1, and the upper end of the right side surface portion 20 in the case of the box body 1').

[0046] Furthermore, although the folding line C6 is provided between the side surface adhesive portion 130 and the top surface adhesive portion 140, the folding line C6 may be omitted. In other words, since the cutting line K3 is provided between the side surface adhesive portion 130 and the top surface adhesive portion 140, even if the folding line C6 is not provided, when the top surface adhesive portion 140 is to be bent relative to the side surface adhesive portion 130, the extension of the cutting line K3 becomes the folding line, and the folding can be performed.

[0047] Furthermore, although the double-sided adhesive tape 150 is provided on the side surface adhesive portion 130 and the top surface adhesive portion 140, adhesive means other than double-sided adhesive tape may be used. In other words, the boxes 1, 1' may be configured without the double-sided adhesive tape 150, and when adhering them to the box bodies 1, 1' to be connected, adhesive means may be provided on the side surface adhesive portion 130 and the top surface adhesive portion 140 (for example, adhesive may be applied) before they are attached to the box bodies 1, 1' to be connected.
