Description

Foldable paper packaging box {COLLAPSIBLE PAPER PACKING BOX}

The present invention relates to a foldable packaging box in a form in which an inner box and an outer box each made of paper are attached, and is handled or distributed in a folded state to be assembled by a user to complete the shape of the box.

Since it was invented for writing, paper has also been expanded for packaging purposes. Packaging using paper is divided into a method of directly wrapping paper around an object, a method of manufacturing it in a bag or envelope form so that the object can be put in and carrying it directly, and a method of manufacturing a box having the shape of a container.

Among them, there are various types of paper boxes, and there are also various production methods. As a kind of paper box, a box using light and durable cardboard was invented, and the cardboard box played an important role in the transportation field.

Another form of paper box, a set up box with a lid, was invented as a way to emphasize luxury while protecting fragile contents. On the other hand, since the setup box is handled and distributed as completed, it takes up a lot of space and has a high risk of being damaged during handling.

Collapsible or foldable boxes overcome the shortcomings of these setup boxes, reduce storage costs by taking up less space, and have a professional and mass-producible manufacturing process, yet users simply assemble the box to complete the box. It has the advantage of being able to do it. In addition to the above-mentioned corrugated cardboard box, there are manila boxes using thick paper (cardboard), and laminated boxes made by overlapping cardboard and cardboard.

On the other hand, there is also a box (also referred to as'savari box' in Korea) that emphasizes the luxury by wrapping the outer surface of the hardboard paper with adhesive to prevent the seam from being exposed. Among these boxes, there is also a form in which an inner box and an outer box each made of a hard wick and an outer sheet are attached, and various packaging effects can be given through printing, and since it enhances morphological aesthetics, it is often used as an expensive product box. However, manufacturing is complicated, it is difficult to fold due to the adhesive state of the hard wick and the outer paper, and even if folded, the hard wick and the outer paper are damaged, so that it is difficult to construct a folded box. In order to overcome this, some of the prior art alleviated the inhibition of the folding of the hard wick by cutting the part of the outer paper corresponding to the part where the hard wick is folded, and this was configured as a folding type.

Nevertheless, prior art forms the inner box of the combination of the hard wick and the outer paper in a folded type, and it is difficult to completely fold, so the volume increases, and as a result of excessive pressure applied to maintain the folded state and reduce the volume, pressure marks There is a problem that a factor that degrades the aesthetics is generated.

Hereinafter, with reference to the accompanying drawings, a folding type paper packaging box related to the present invention will be described in detail.

As shown in Figure 1, the folding-type paper packaging box 100 related to the present invention is a form in which an inner box 110 and an outer box 150 are combined. The upper surface of the inner box 110 is open, and the outer box 150 is configured to surround the inner box 110 to cover the upper surface of the inner box 110. After the folding-type paper packaging box 100 is manufactured as shown in FIG. 1, it can be handled and distributed in a completely folded state as shown in FIG. 2.

The inner box 110 has a bottom surface 111, a pair of first side surfaces 112 and 113 connected to the bottom surface 111, and a pair of first side surfaces 112 and 113, as long as it is orthogonal to the It has a pair of second sides 114, 115. The top surface opposite to the bottom surface 111 is open. In order for the first side (112, 113) and the second side (114, 115) to be folded from an erected state with respect to the bottom surface 111, the first side (112, 113) is mutually narrowed, and the second side (114) , 115) are mutually divided. A fold line 119 exists on the second side surfaces 114 and 115 so that they can be folded in a predetermined shape in the process of being folded in an erect state. The fold line 119 is formed in a diagonal direction on the edge side of the pair of second side surfaces 114 and 115, as shown in FIG. 2. The fold line 119 of the inner box 110 induces that the first side surfaces 112 and 113 are mutually narrowed, the pair of second side surfaces 114 and 115 are mutually widened, and the inner box 110 is folded flat. . These fold lines 119 are of the third hard wick fold line 129 (see FIG. 4) of the first hard wick 120 to be described later and the partial cut-out line 131 (see FIGS. 3 and 4) of the inner outer paper 130 Formed by combination.

The enclosure 150 includes a support surface 151 to which the bottom surface 111 is attached, a cover surface 152 covering the upper portion of the inner box 110, and a side support surface overlapping the pair of second side surfaces 114 and 115 (153, 154) and, it may be formed in a shape having a wing surface 155 that again covers the side support surface 154 of the edge.

The outer box 150 or the inner box 110 has a pair of second side surfaces 114 and 115 that are erected in a state where the inner box 110 is folded with respect to the bottom surface 111, and then can be maintained in an erect state (that is, folded A double-sided tape 156 may be provided to attach the second side surfaces 114 and 115 to the enclosure 150 so as not to be arbitrarily folded by the line 119.

A magnet 157 may be provided in the inner box 110 or 150 so that the wing surface 155 at the end of the outer box 150 may maintain a closed state with respect to the inner box 110.

Hereinafter, a specific configuration and operation of the folded paper packaging box 100 related to the present invention will be described in detail through the manufacturing process of the box.

3 to 6 show a process of manufacturing the inner box 110 according to an embodiment related to the present invention, and FIGS. 7 to 8 show a process of manufacturing the case 150, and FIGS. 9 to 10 Shows the process of attaching the inner box 110 and the enclosure 150.

First, FIG. 3 is an exploded perspective view showing a state before the elements constituting the inner box 110 are adhered to each other, and FIG. 4 is an exploded perspective view showing a state viewed from above by inverting the arrangement state of FIG. 3, and FIG. 6 3 is a perspective view showing a state in which the first hard wick 120 and the inner outer surface 130 are bonded and assembled in the form of a box to form the inner box 110.

As shown in FIG. 3, the inner box 110 is in a form in which a thick first hard wick 120 and a thin inner outer box 130 surrounding the first hard wick 120 are laminated. The first hard wick 120 determines the shape and size of the inner box 110, and the inner outer surface 130 covers the surface of the first hard wick 120 to make the exterior look beautiful. The first hard wick 120 and the inner outer surface 130 are formed by cutting each paper as a material into an appropriate size.

The first hard wick 120 is a first hard wick to form the first hard wick bottom surface 121 and the first side surfaces 112 and 113 constituting the bottom surface 111 of FIGS. 1 and 2. On the first hard wick side (122, 123) to form a pair of the first hard wick side (122, 123) and the second side (114, 115) facing each other connected to the wick bottom surface 121 It has a pair of orthogonal second hard wick sides (124, 125). The inner outer cover 130 includes a first hard wick bottom surface 121, a portion corresponding to the first hard wick side surfaces 122 and 123 and the second hard wick side surfaces 124 and 125, and It has a margin so as to wrap around an edge portion of the wick 120. The width of this margin may vary from case to case.

The first hard wick 120 has several folds in the first hard wick 120 so that the thick first hard wick 120 is erected in a flat state to have the shape of the inner box 110 or completely folded so that parts thereof can be completely overlapped with each other. Is formed in advance. These fold lines may be formed in different cross-sectional shapes depending on the function, and each cutter may be used in the manufacturing line of the factory.

First, between the first hard wick bottom surface 121 and the first hard wick side (122, 123) so that the first hard wick side (122, 123) can be folded with respect to the first hard wick bottom surface (121). The first hard wick fold line 127 is formed. The first hard wick fold line 127 is formed so that the inner box 110 is erected at 90 degrees as shown in FIG. 6 and supports a folded state of 180 degrees as shown in FIG. 2.

Between the first hard wick bottom surface 121 and the second hard wick side (124, 125) so that the second hard wick side (124, 125) can be folded with respect to the first hard wick bottom surface (121) The wick fold line 128 is formed. The second hard wick fold line 128 is used to erect the inner box 110 at 90 degrees, as shown in FIG. 6, and returns to its original state when the inner box 110 of FIG. 2 is folded.

4, when the second hard wick side (124, 125) is converted to a folded state, the second hard wick side (124, 125) is partially folded so that it is symmetrical to the second hard wick side (124, 125). A pair of third hard core fold lines 129 are formed. This third hard wick fold line 129 is not utilized in the state erected as the inner box 110 as shown in FIG. 6, but the first side surfaces 112 and 113 are narrowed and the second side surfaces 114 and 115 as shown in FIG. ) Becomes the primary element of the fold line 119 to open. At this time, the inner outer surface 130 is in a state that the entire surface is attached to the first hard wick 120 by an adhesive, so that the first hard wick 120 prevents folding along the third hard wick fold line 129 can do. To this end, as shown in Figs. 3 and 4, the inner outer surface 130 has the second hard wick side (124, 125) in a position corresponding to the third hard wick fold line 129 is erected to the folded state. The partial perforation line 131 is formed so that it can be torn apart and open. The partial perforation line 131 refers to that the blade is partially formed along the line direction, and is formed to have only a minimum number of connection portions so that the shape is constant when torn off.

As shown in the enlarged portions of FIG. 3, the first and second hard interlining fold lines 127 and the second hard interlining fold lines 128 include cutout-type grooves in which paper is cut to a predetermined depth along the line and removed. have. Specifically, the first hard core fold line 127 has a'W'-shaped cross section, and the second hard core fold line 128 has a'V'-shaped cross section. The'W' shape of the first hard wick fold line 127 means that there are a plurality of cut grooves, and when the first side surfaces 112 and 113 are folded 180 degrees as shown in FIG. 2, the first hard wick fold line ( 127) Minimizes folding is prevented by interference and friction of remaining parts of itself. Accordingly, the problem of erecting the first side surfaces 112 and 113 in the folded state is also solved, and the space may be reduced when the box is stacked and stored, and excessive force may be minimized for complete folding. On the other hand, the second hard wick fold line 128 may have a groove of a'V'-shaped cross section having one groove so as to be erected as shown in FIG. 6 or suitable for deformation to a degree to be in an original state as shown in FIG. 2.

5 is a cross-sectional view showing a specific shape and modified examples of the first hard wick fold line 127 of FIG. 3. As described above, the first hard wick fold line 127 may have a cut-out groove having a'W'-shaped cross section. In this case, as shown in FIG. 5(a), the depths of the two grooves 127a and 127b may be the same. Unlike this, as shown in FIG. 5(b), one of the two grooves 127a' may be formed deeply with respect to the other one 127b'. When it is converted to a folded state due to the difference in depth, folding is naturally induced to the thinner side of the remaining part of the two grooves, and the angle of the edge according to the folding is'correct' (meaning that it is not round or blunt). ). In this case, the deep groove 127b' is biased toward the bottom surface 121 of the first hard wick so that the angle between the bottom surface and the side surface can be more accurately implemented.

Referring to FIG. 4, the third hard core fold line 129 is formed by half-cutting a predetermined depth along the line direction. Here,'half-cutting' means that the blade is used, but only partially (only a certain depth) without cutting out by the blade. The third hard wick fold line 129 does not cause the second hard wick sides 124 and 125 to be folded for an erect state as shown in FIG. 6, but when folded as in FIG. 2, the inner outer surface 130 The partial perforation line 131 is easily torn off, and the rigidity of the second side surfaces 114 and 115 is retained in order to be erected as a box as shown in FIG. 1.

7 to 8 describe a process of manufacturing the enclosure 150 through.

As shown in FIG. 7, the enclosure 150 is also formed in a form in which thick paper and thin paper are laminated. Specifically, the enclosure 150 is a second hard wick 160, a second hard wick 160, a second hard wick 160 that surrounds the outside of the second hard wick 160 and has a margin of the outer case 170 and the outer case 170 It may have an enclosure to 180 covering the inner side of the wick 160.

Each of the second hard wick 160, the outer case 170, and the outer case 180 may be manufactured through a simple process by cutting one sheet of paper into an appropriate size. This feature can increase mass production and reduce manufacturing cost compared to manufacturing the second hard wick 160 by arranging the second hard wick 160 into several divided pieces and attaching the outer case and the outer case.

In response to the support surface 151, the cover surface 152, the side support surfaces 153 and 154 and the wing surface 155 constituting the enclosure 150 of FIG. 1, the second hard wick 160 is also a wick bottom A surface 161, a wick cover surface 162, a wick support surface 163 and 164, and a wick wing surface 165 may be provided. At this time, an enclosure wick fold line 167 is formed to divide the sides and allow mutual folding. Referring to FIG. 7, the enclosure wick fold line 167 includes a conout-type groove having a'V'-shaped cross section. The outer box wick fold line 167 does not have a rapid folding angle like the first hard wick fold line 127 of the inner box 110, but contributes to implementing an accurate angle as an important element constituting the appearance of the box.

When the inner box 110 and the outer box 150 are manufactured in this way, they are aligned for attachment as shown in FIG. 9 in the next process. Before alignment or after attachment, the folded first side (112, 113) of the inner box (110) is erected on the side support surfaces (153, 154) of the enclosure (150), and the first side (112, 113) is erected easily. Double-sided tape 156 may be pre-attached so that it can be maintained.

After attaching the bottom surface 111 of the inner box 110 to be aligned with the support surface 151 of the outer box 150, it is used as a box or made into a folded state as shown in FIG. 11. That is, as shown in FIGS. 10 and 11, the first side (112, 113) of the inner box 110 is narrowed by the first hard wick fold line 127, and the second side (114, 115) is the second hard wick. It is opened by the fold line 128, and in this process, the partial perforation line 131 is torn off, and the second side surfaces 114 and 115 are partially (triangled) folded along the third hard wick fold line 129. . The first hard wick fold line 127 and the second hard wick fold line 128 are located inside the inner box 110, and in any case erected or folded, the cutout portion is not exposed, thereby improving the appearance.

As shown in FIG. 11, in a state where the inner box 110 is folded, the consumer (a store that sells goods, etc.) raises the inner box 110 and simply restores it to the shape of a box, and then puts the object and covers the outer box 150. The folding-type paper packaging box 100 as in the present invention can be restored to the appearance of a high-quality box by simply erecting it if necessary, while being handled in a folded state, so that the customer does not need an additional space for furnishing the assembled boxes.

3 to 6 show that both the first hard wick fold line 127 and the second hard wick fold line 128 having cutout grooves are the first side surfaces 112 and 113 and the second side surfaces 114 and 115. ) Is erected with respect to the bottom surface 111 or the first hard wick side (122, 123) and the second hard wick side (124, 125) are erected with respect to the first hard wick bottom surface 121 When, this is the case where it is located inside the box.

In contrast, FIGS. 13 to 14 are diagrams showing a process of manufacturing the inner box 210 according to another embodiment related to the present invention. In the inner box 210 of the present example, a first hard wick fold line 227 having a cut-out groove exists outside the inner box 210 when the inner box 210 is erected. The cut-out type groove is formed in the first hard wick fold line 227, and the second hard wick fold line 228 is formed by half-cut cutting. As in the previous embodiment, the third hard wick fold line 229 is formed by half-cut cutting, and a partial cut line 231 is formed at the corresponding position of the inner box outer sheet 230.

The cut-out type groove having a'V'-shaped cross section of the first hard wick fold line 227 is the inner outer box 230 that is wrapped around the first hard wick 220 and the first hard wick fold line 227 In the process of folding 180 degrees, it is compressed by the area around the second hard wick fold line 228 to prevent complete folding or to minimize excessive pressure for folding.
