Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, a packaging box containing a product is transported, and the packaging box is opened when the product is used. Usually, for this type of packaging box, it is common to open the top plate and then take out the product accommodated inside. Also, there is known a configuration in which a cuttable (breakable) opening piece is formed in a part of the top plate, and the contents accommodated inside are taken out through an opening having a shape corresponding to the cut opening piece.

[0005] However, when the product is, for example, a packaged product for distribution to employees, the product may remain. In this case, since the opened packaging box is placed as it is in a predetermined storage location, dust, dirt, etc. may enter through the opening during the next use, which is not hygienically preferable. Further, since the opening is formed in a partial area of the top panel, after a certain amount of the product has been taken out, a hand is inserted into the opening and pushed in up to near the bottom to take out the product. This operation requires labor for the person taking out the product, thus imposing a physical burden.

[0006] An object of the present invention is to solve such conventional problems, and to provide a packaging box that can reduce the physical burden when taking out a product from the packaging box and can surely suppress the intrusion of external dust, dirt, etc. even when it is once stored after being opened.

Mode for Carrying Out the Invention

[0010] The packaging box according to the embodiment of the present invention will be described below with reference to FIGS. 1 to 3. FIG. 1 is a developed view of the packaging box according to the embodiment. FIG. 2 is a view showing the appearance of the packaging box, where (a) is a view in a state where the take-out piece is closed, and (b) is a view in a state where the take-out piece is opened. FIG. 3 is a view for explaining the structure of the take-out piece of the packaging box according to the embodiment. In addition, in this specification, the meanings of "the same", "identical" and "equal" may include the range of errors generally acceptable in the technical field to which the present invention belongs.

[0011] As shown in FIG. 1, the packaging box 1 has a front panel 13, a first side panel 14, a bottom panel 15, and a second side panel 16 connected in this order. On the front panel 13, a substantially rectangular outer flap (outer lid piece) 13a is connected (extended) to the upper edge in a direction orthogonal to the connection direction, and a substantially rectangular outer flap 13b is connected to the lower edge in a direction orthogonal to the connection direction. On the bottom panel 15, a substantially rectangular outer flap 34a is connected to the upper edge in a direction orthogonal to the connection direction, and a substantially rectangular outer flap 34b is connected to the lower edge in a direction orthogonal to the connection direction. The outer flap 13a is separated from the front panel 13 by a front fold (crease) line 25a, and the outer flap 13b is separated from the front panel 13 by a front fold (crease) line 25b. The outer flap 34a is separated from the bottom panel 15 by a bottom fold (crease) line 35a, and the outer flap 34b is separated from the bottom panel 15 by a bottom fold (crease) line 35b. The region 13a1 (the region between the upper end portion of the outer flap 13a and the broken line portion below it) and the region 13b1 (the region between the lower end portion of the outer flap 13b and the broken line portion above it) are the ranges where tape is to be pasted at the end of assembly. As shown in the figure, a broken line may be printed in advance, or nothing may be displayed. The region 34a1 (the region between the upper end portion of the outer flap 34a and the broken line portion below it) and the region 34b1 (the region between the lower end portion of the outer flap 34b and the broken line portion above it) are the ranges where tape is to be pasted at the end of assembly. As shown in the figure, a broken line may be printed in advance, or nothing may be displayed. Note that the packaging box 1 houses, for example, but is not limited to, portable cooling packs, portable heat packs, etc.

[0012] On the first side panel 14, a substantially rectangular inner flap (inner lid piece) 24a is connected to the upper edge in a direction orthogonal to the connection direction, and a substantially rectangular inner flap 24b is connected to the lower edge in a direction orthogonal to the connection direction. On the second side panel 16, a substantially rectangular inner flap 44a is connected to the upper edge in a direction orthogonal to the connection direction, and a substantially rectangular inner flap 44b is connected to the lower edge in a direction orthogonal to the connection direction. The inner flap 24a is separated from the first side panel 14 by a side fold line 28a, and the inner flap 24b is separated from the first side panel 14 by a side fold line 28b. The inner flap 44a is separated from the second side panel 16 by a side fold line 38a, and the inner flap 44b is separated from the second side panel 16 by a side fold line 38b. Note that the area surrounded by the broken line 17a and the area surrounded by the broken line 17b are the areas where the tape is to be attached at the end of assembly. It may be printed with a broken line in advance as shown in the figure, or nothing may be shown. The area surrounded by the broken line 18a and the area surrounded by the broken line 18b are the areas where the tape is to be attached at the end of assembly. It may be printed with a broken line on the surface in advance as shown in the figure, or nothing may be shown.

[0013] Furthermore, an adhesive piece 19 extends along the side (edge) of the front panel 13 opposite to the back panel 15, and the adhesive piece 19 is adhered to the end of the second side panel 16 opposite to the back panel 15 during assembly. The lengths of the front panel 13 and the back panel 15 in the connection direction are substantially equal to each other, and the lengths of the first side panel 14 and the second side panel 16 in the connection direction are substantially equal to each other. The front panel 13, the first side panel 14, the back panel 15, the second side panel 16, and the adhesive piece 19 are each separated by fold lines (crease lines) 40, 41, 42, 43.

[0014] <Removable piece> In a part of the area of the front panel 13 and near the end on the bottom surface side, a take-out piece 20 composed of an opening piece 21 and a pressing piece 22 is formed. The take-out piece 20 is openable and closable to the front side and the back side with the fold line 25b as a rotation axis. The shape of the take-out piece 20 is such that the upper part in the center is arcuate on the outer periphery or semi-circular and substantially rectangular as a whole, but it is not limited to this if the upper part in the center is convex. The pressing piece 22 has a function of facilitating pressing when opening the packaging box 1 in the assembled state.

[0015] An arc-shaped first breaking line (perforation) 32 is formed from the edge of the front panel 13 toward the central part side, and second breaking lines 31a and 31b are formed from both ends of the first breaking line 32 toward the edge of the front panel 13 respectively (see FIGS. 2(a) and 3). The second breaking line 31a is formed so as to move away from the first breaking line 32 toward the left in the horizontal direction in the front view, and then approaches the bottom surface part vertically before reaching the folding line 43. The second breaking line 31b is formed so as to move away from the first breaking line 32 toward the right in the horizontal direction in the front view, and then approaches the bottom surface part vertically before reaching the folding line 43. A folding line (crease line) 25b is formed to connect (join) the bottom surface side end of the second breaking line 31a and the bottom surface side end of the second breaking line 31b.

[0016] Breaking lines 31a, 31b, and 32 for opening are formed so that the bottom surface side ends of the second breaking line 31a and the second breaking line 31b overlap with both ends of the fold line 25b. The first breaking line 32 is composed of a first cut part 32a and a first connecting part 32b, the second breaking line 31a is composed of a second cut part 31a1 and a second connecting part 31a2, and the second breaking line 31b is composed of a second cut part 31b1 and a second connecting part 31b2.

[0017] The length of the first cut portion 32a is longer than the length of the second cut portion 31a1. The length of the first cut portion 32a is longer than the length of the second cut portion 31b1. The length of the first cut portion 32a is longer than the length of the first connecting portion 32b. The length of the second cut portion 31a1 is the same as the length of the second connecting portion 31a2, and the length of the second cut portion 31b1 is the same as the length of the second connecting portion 31b2.

[0018] <Usage Example> The area surrounded by the first broken line 32 is the pressing area, and the area surrounded by the second broken lines 31a, 31b and the folding line 25b is the storage item extraction area. In the assembled state, when the pressing area is pressed from the front to the back, the pressing piece 22 is pushed in. When the pressing area is further pressed from the front to the back, the opening piece 21 connected to the pressing piece 22 is also pushed in, and the extraction piece 20 is separated from the front panel 13 along the first broken line 32 and the second broken lines 31a, 31b, thereby opening that area and revealing the opening (extraction opening) 23 (see Fig. 2(b)).

[0019] <Modification Example 1> The first broken line 32 and the second broken lines 31a, 31b may be in a zigzag shape (not shown). Although the embodiment has been described with a hexahedral packaging box, it may be a polyhedron (for example, an octahedron, etc.) as long as it has an extraction piece with the above structure on the bottom side of at least one surface.

[0020] <Effects of the Embodiment> (1) A packaging box 1 having a side surface composed of a front panel 13, a back panel 15, a first side panel 14, and a second side panel 16. Near the end portion on the bottom side of the front panel 13, an opening 23 is formed, and the opening 23 is made openable and closable by an extraction piece (opening and closing body) 20. According to the configuration of the above-described packaging box 1, since the opening 23 that functions as an extraction port is located at the bottom, the storage item accommodated in the packaging box 1 can be easily taken out. Since it is at the bottom, if the storage item is flat like a pack shape, it will always be placed in front of the opening 23 after being taken out, so it can always be easily taken out. (2) From the edge (crease line 25b) of the front panel 13, which is one side, an arc-shaped first break line 32 is formed toward the central part side, and two second break lines 31a and 31b are formed from both ends of the first break line 32 toward the edge of the front panel 13 respectively. It has a crease line 25b that connects one end of one second break line 31a and one end of the other second break line 31b. The area surrounded by the first break line 32 is defined as the pressing area, and the area surrounded by the two second break lines 31a and 31b and the crease line 25b is defined as the container extraction area. Therefore, it can be easily broken by pressing on the pressing area and the container extraction area, making it easier to open. Also, when fitting the opening piece 20 composed of the pressing piece 22 and the extraction piece 21 back into the opening 23 after extraction, it is easier to close the opening 23. Also, during use and storage, the opening 23 can be closed (see Fig. 2(a)), so it is possible to prevent dust, dirt, etc. from the outside from entering the inside of the box. (3) The first break line 32 consists of a first cut portion 32a and a first connecting portion 32b, and the second break lines 31a and 31b each consist of a second cut portion 31a1, 31b1 and a second connecting portion 31a2, 31b2. The length of the first cut portion 32a is longer than the lengths of the second cut portions 31a1 and 31b1. Therefore, at the time of breaking, the pressing area is easier to break than the container extraction area, making it easier to open. Also, when moving the assembled storage box with the container inside by a truck or the like and transporting it to a predetermined place after movement, since the break lines in the extraction area are made thick, it is difficult to break and the risk of the container flowing out of the box can be avoided. (4) Since the length of the first cut portion 32a is longer than the length of the first connecting portion 32b, the pressing area is easier to break than the container extraction area, making it easier to open. (5) Since the length of the second cut portion and the length of the second connecting portion are the same, the pressing area is easier to break than the container extraction area, making it easier to open. (6) Since the first broken line 32 and the second broken lines 31a and 31b are zigzag-shaped, the frictional force due to the zigzag shape increases, making it easier to close the opening when returning the extraction piece 20 composed of the pressing piece 22 and the opening piece 21 after extraction (see Fig. 2(a)).

[0021] Note that the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the gist of the present invention.
