Description

The present invention relates to a packaging box with a window. The invention also relates to a template for making (assembling) a packaging box with a window.

Kagami rice cakes, toys, miscellaneous goods, and other products are sometimes displayed in stores in cardboard packaging boxes. A packaging box having a window covered with a transparent resin film on the top or front surface of the packaging box is used so that the products in the packaging box can be seen from the outside.

When disposing of the paper packaging box and the resin film separately, it is necessary to separate the resin film from the packaging box. Patent Literature 1 discloses that a pair of fracture lines are provided in a part of the periphery of a window hole formed in a front plate. By pressing between the pair of breaking lines, the peripheral portion of the resin film is peeled off from the peripheral portion of the window hole.

JP 2013-136394 A

Since the separation of the resin film from the packaging box is the step of discarding the packaging box, the inside of the packaging box is generally empty. When a hollow packaging box is pressed against a pair of tear line-provided surfaces, the packaging box tends to collapse before it tears along the tear lines. In that case, the resin film cannot be peeled off from the packaging box even if the space between the pair of breaking lines is pressed.

SUMMARY OF THE INVENTION An object of the present invention is to enable a resin film to be reliably and easily separated from a packaging box.

A packaging box with a window according to the present invention is a packaging box formed into a rectangular parallelepiped shape by folding a sheet of cardboard, and the side or rear part of the packaging box serves as an entrance and exit for stored items, and the entrance and exit is the bottom part. Or it is closed by a cover surface part that is continuous from the top part and is bent at a right angle, and a window is formed on the top part of the packaging box, on the front part, or from the top part to the front part, and a transparent resin film that closes the window The peripheral part is adhered to the top part, to the front part, or to the inside of the window frame peripheral part of the window formed on the top part and the front part, and the doorway is defined on the surface part where the window is formed. A broken line is formed extending in a direction connecting a corner of the rectangular edge portion and the window frame of the window.

By opening the lid surface portion, a doorway through which stored items are taken in and out is opened in the side surface portion or the rear surface portion. Since the packaging box is rectangular parallelepiped, the doorway is square. The edges of a rectangular doorway are defined by the edges of the top, bottom, front and rear (if the doorway is located on the side) or by the top, bottom and left and right sides (if the doorway is located on the rear) defined by the edge of the

According to this invention, a breaking line is formed on the surface portion on which the window is formed, and the breaking line extends in a direction connecting the corner of the rectangular edge defining the doorway and the window frame of the window. , the peripheral edge of the window frame (the peripheral edge of the surface on which the window is formed) of the window can be easily and reliably torn along the breaking line. When a tear along the fracture line is formed in the window frame periphery, the window frame periphery can be peeled up to separate the transparent resin film from the window frame periphery. Since the edge of the transparent resin film is exposed at the portion where the window frame peripheral edge and the transparent resin film are separated, the edge of the transparent resin film can be picked up by hand. By pinching the edge of the transparent resin film and tearing off the transparent resin film from the packaging box, the entire transparent resin film can be separated from the packaging box.

The break line may, for example, be the shortest distance from the corner of the rectangular edge defining the doorway to the window frame closest to the corner of said rectangular edge, or to the adjacent window frame. good. Moreover, the cuts forming the fracture line may be short or long, and short cuts and long cuts may be mixed. Moreover, the breaking line may be linear, or part or all of it may be arcuate. Arc-shaped break lines are employed, for example, when a break line is not formed on a specific pattern printed on a packaging box.

Preferably, a flap that can be bent at right angles is provided inside the lid surface. Since the flap can be grasped by hand, it is easy to break the peripheral edge of the window frame along the breaking line and separate it from the transparent resin film.

In one embodiment, the break line begins at the corner of the square edge and ends at the window frame. The edge of the window frame can be neatly torn along the breaking line.

In another embodiment, the break line begins at a point away from the corner of the square edge and ends at the window frame. By not forming the breaking lines near the corners of the square edges, it is possible to suppress the decrease in strength or the susceptibility to breakage of the packaging box.

Preferably, when the starting point is set at a position away from the corner of the square edge, an auxiliary break line extending from the starting point into two so as to sandwich the corner of the square edge is attached to the window. is formed in the range between the corner of the square edge of the face on which the is formed and the start point. Auxiliary breaking lines can assist in tearing the peripheral edge of the window frame from the corner of the square edge to the starting point (a position away from the corner of the square edge).

The invention also provides a template for making a box with a window formed into a rectangular parallelepiped. The packaging box made by the paper pattern according to the present invention has an entrance and exit for stored items on the side or rear surface, and is closed by a cover surface that is continuous from the bottom or top surface and is bent at right angles. A window is formed on the front surface or from the top surface to the front surface, and the surface portion on which the window is formed extends in the direction connecting the corner of the rectangular edge defining the doorway and the window frame of the window. A line is formed.

Fig. 1 shows a sheet of pattern paper (blank) for making a packaging box for kagami-mochi, and Fig. 2 is a perspective view of the packaging box for kagami-mochi assembled using this pattern. FIG. 2 shows a packaging box for kagami-mochi in which a set of kagami-mochi is stored.

FIG. 1 shows a developed view of a packaging box, showing the outer surface of a single template (blank) 1A punched out of cardboard. Fold lines for mountain folds are indicated by one-dot chain lines, and fold lines for valley folds are indicated by two-dot chain lines.

In one paper pattern 1A for forming the packaging box 1B (see FIG. 2), the bottom part 14, the front part 11, the top part 12, the rear part 13 and the paste margin 13A are continuous in a horizontal row. On the bottom part 14 is one side part 15 (the right side when the packaging box is viewed from the front) (Since this side is the surface part that closes the entrance and exit of the stored items, this side part is hereinafter referred to as the "lid surface part 15". ) are formed continuously in a direction perpendicular to the horizontal row direction. A locking tongue piece 15A is continuously formed at the tip of the lid face portion 15. As shown in FIG. Further, substantially rectangular side inner flaps 17A and 17B continuously extending in the same direction as the lid surface portion 15 extend are formed on the front surface portion 11 and the rear surface portion 13, respectively.

The other side surface portion (the left side surface when the packaging box 1B is viewed from the front) extends continuously from the front surface portion 11, top surface portion 12, rear surface portion 13 and bottom surface portion 14 to the side opposite to the lid surface portion 15. It is formed by a side piece 16A, an upper side piece 16B, a side piece 16C and a lower side piece 16D. When the packaging box 1B is formed, these parts 16A to 16D partially overlap each other to close the left side of the packaging box 1B. The portions 16A and 16C are formed with arc-shaped side portions 18a and 18b that mesh when they overlap each other. Portions 16B and 16D are generally trapezoidal.

A window 20 is formed from the front surface portion 11 to the upper surface portion 12 . The window 20 is for allowing the kagami-mochi set stored in the packaging box 1B to be seen from the front and top (see-through window). is provided. The transparent resin film 21 has its peripheral portion adhered (glued) to the inside of the window frame peripheral portion of the window 20 opened in the front portion 11 and the upper portion 12 . In this embodiment, the window of the front face portion 11 is formed in a rectangular shape, and the window of the top face portion 12 has an outward arc shape at its tip (portion close to the rear face portion 13). The shape of the window 20 can be designed arbitrarily.

A breaking line (perforation, dotted line) 41 extending linearly in the direction connecting the boundary point a of the front surface portion 11, the bottom surface portion 14 and the lid surface portion 15 and the window frame angle h of the window 20 closest to the boundary point a, A window 20 is formed in the front part 11 which is opened. The breaking line 41 is formed by discontinuously connecting a plurality of cuts, and the shape of the cuts forming the breaking line 41 may be a short straight line or a small hole. Along the breaking line 41, the window frame peripheral portion of the front portion 11 is easily torn. In addition, the position of a, which is one end (start point) of the break line 41, does not necessarily have to strictly match the boundary points of the front surface portion 11, the bottom surface portion 14, and the lid surface portion 15, and even if there is a slight deviation, for example It may be the corner of the flap 17A that connects to the front portion 11.

When the paper pattern 1A shown in FIG. 1 is folded along the folding lines and assembled, a rectangular parallelepiped packaging box 1B as shown in FIG. 2 is formed. The paste margin 13A of the rear surface portion 13 is glued to the inner surface of one side of the bottom surface portion 14. - 特許庁The left side portion is folded so that the portions 16A to 16D are inside, and the portions 16A and 16C are folded along preformed folding lines. The range of tip portions from the folding lines of the portions 16A and 16C overlaps the portions 16D and 16B, and this overlapping portion is glued. By unfolding the folded portions 16A and 16C along the folding lines, the left side portion is formed by the portions 16A to 16D. At this time, the arcuate sides 18a and 18b mesh with each other. The left side is of the so-called auto-bottom type, but it is not necessarily the auto-bottom type.

The right side of the packaging box 1B serves as the doorway for the kagami-mochi set. After the rice cake set 30 is stored in the packaging box 1B, the inner side flaps 17A and 17B are bent at right angles to cover the front and rear ends of the doorway. Finally, the locking tongue piece 15A of the lid surface portion 15 is bent at a substantially right angle, the lid surface portion 15 is bent at a right angle at the boundary with the bottom surface portion 14, and the locking tongue piece 15A is aligned along the inner surface of the upper surface portion 12 for packaging. Insert into box 1B. Assembly of the packaging box 1B is completed. The packaging box 1B containing the kagami-mochi set 30 is displayed in the store in this state.

Referring to FIG. 2, in the assembled state of the packaging box 1B, the break line 41 is a rectangular edge that defines the entrance and exit of the contents of the packaging box 1B (the rectangular area closed by the lid surface portion 15 in FIG. 2). It connects the corner a of the part and the window frame angle h of the window 20 . The breaking line 41 is formed in the surface portion on which the window 20 is formed among the plurality of surface portions provided in the packaging box 1B, and is formed in the front surface portion 11 and/or the upper surface portion 12 of the packaging box 1B. It is formed so as to extend from the corner of the edge toward the window frame of the window 20 . In the packaging box 1B, the break line 41 is the boundary point of the front surface portion 11, the bottom surface portion 14 and the lid surface portion 15, that is, the corner located in the lower left corner among the four corners of the rectangular edge when the doorway is viewed from the front. The shortest distance extends from a to the window frame corner h closest to corner a.

The customer sees the kagami-mochi set 30 (for example, kagami-mochi-shaped packs placed on three sides and various decorations attached) in the packaging box 1B through a window (see-through window) 20 covered with a transparent resin film 21. be able to. When taking out the rice cake set 30 from the packaging box 1B, the lid surface portion 15 of the packaging box 1B is opened.

3 to 6 show how to separate (separate) the transparent resin film 21 covering the window 20 from the packaging box 1B.

The front part 11 of the packaging box 1B is turned upward, the lid surface part 15 is held with the left hand, and the flap 17A or the front part 11 where the flap 17A is connected with the right hand (the window frame peripheral part of the front part 11 where the transparent resin film 21 is not adhered). (Fig. 3).

The flap 17A pinched with the right hand is turned over to the upper right (Fig. 4). As described above, the front part 11 with the window 20 has a breaking line 41 extending linearly in a direction connecting the corner a to the window frame angle h of the window 20. Therefore, the starting point is the corner a. , and the corner h as an end point, the edge of the window frame of the front part 11 can be easily torn along the breaking line 41 .

Flap 17A is flipped up (Fig. 5). The peripheral portion of the window frame of the front face portion 11 in the range continuous with the flap 17A is peeled off from the transparent resin film 21. As shown in FIG.

By peeling off the window frame peripheral portion of the front face portion 11, the edge portion of the transparent resin film 21 adhered to the window frame peripheral portion is exposed in an exposed state. By pinching the edge of the exposed transparent resin film 21 with the right hand and peeling it off from the packaging box 1B, the entire transparent resin film 21 is separated from the packaging box 1B (Fig. 6). The transparent film can be reliably and easily separated from the packaging box 1B.

The lid surface portion 15 may be continuous with the top surface portion 12 instead of the bottom surface portion 14 . Also, the doorway of the rice cake set 30 may be formed on the rear surface instead of the right side surface of the packaging box 1B.

FIG. 7 shows a paper pattern 1C of a modified packaging box. It is different from the packaging box template 1A shown in FIG. 1 in that the length of each of the plurality of cuts forming the breaking line 42 is long. The length of the cut that constitutes the breaking line can be arbitrarily designed.

FIG. 8 shows a template 1D of a packaging box of still another modification. It is different from the packaging box template 1A shown in FIG. 1 in that the end point of the breaking line 43 is not at the window frame corner of the window 20, but at a point k on the window frame side slightly off the window frame corner. A point k where the end point of the breaking line 43 is located is provided on the side of the window frame along the direction in which the flap 17A is turned up (see FIGS. 4 and 5). Thus, the end point of the break line does not necessarily have to be at the window frame angle h of window 20 .

FIG. 9 shows a template 1E of a packaging box of still another modification. In the packaging box template 1A shown in FIG. 1, the breaking line 44 extends in the direction connecting the corner a and the window frame corner h of the window 20 closest to the corner a, but the starting point is the position b slightly away from the corner a. Points are different. By not forming the breaking line 44 in the immediate vicinity of the corner a, which is the corner of the packaging box, it is possible to suppress the decrease in the strength of the packaging box or the susceptibility to breakage of the packaging box.

FIG. 10 shows a paper pattern 1F of a packaging box of still another modification. The packaging box pattern 1E shown in FIG. and the starting point b. The tearing of the window frame perimeter between the corner a and the starting point b can be assisted by the auxiliary tearing line 45a.

FIG. 11 shows a paper pattern 1G for a packaging box of still another modification. The breaking line 43 shown in FIG. 8 is combined with the breaking line 44 shown in FIG. at position k above.

FIG. 12 shows a template 1H for a packaging box of still another modification. It is different from the packaging box template 1A shown in FIG. 1 in that the breaking line 47 is not straight but is formed to connect the corners a and h in an arc. The direction in which the arcuate breaking line 47 protrudes is preferably along the direction in which the flap 17A is turned over (see FIGS. 4 and 5). For example, it is possible not to form the breaking line 47 on a specific pattern printed on the packaging box.

FIG. 13 shows a template 1I for a packaging box of still another modification. A breaking line 48 is formed in the front face portion 11 by combining the straight breaking line described with reference to FIG. 1 and the arc-shaped breaking line described with reference to FIG.

FIG. 14 shows a paper pattern 1J for a packaging box of still another modification. The breaking line 48 shown in FIG. 13 has a straight line near the corner a and an arc near the window frame angle h, whereas the breaking line 49 provided in the pattern paper 1J in FIG. is linear in the vicinity of . 14 also shows that the end point of the break line 49 is at position k on the side of the window frame of the window 20, and that the break line 49 consists of both short and long cuts. The break line 49 shown is different from the break line 48 shown in FIG.

FIG. 15 shows a paper pattern 1K for a packaging box of still another modification. Unlike the templates 1A, 1C to 1J described above, the window 20A is formed only in the upper surface portion 12 and not formed in the front surface portion 11. As shown in FIG. A window 20A of the upper surface portion 12 is closed from the inside with a transparent resin film 21A.

The boundary point c of the front part 11, the top part 12 and the flap 17A is the upper left corner of the square edge defining the square doorway when assembled into a packaging box as shown in FIG. A straight breaking line 41A is formed in the top portion 12 where the window 20 is opened from the corner c to the window frame corner j of the window 20A near the corner c. The edge of the transparent resin film 21A can be exposed by tearing the edge of the window frame of the upper surface portion 12 along the breaking line 41A and turning the edge of the window frame of the upper surface portion 12 over.

It goes without saying that the window may be formed only in the front part 11. As for the packaging box in which the window is formed only in the front part 11, the transparent resin film can be easily separated from the packaging box by forming a breaking line in the same manner as in any one of FIGS. 1 to 14.
