Description

  The present invention relates to a paper box suitable for storing relatively small articles such as food and toys.

A paper box is widely used as a package of articles, and among them, there is one that improves the ease of taking out the contents and the display effect by opening the upper surface widely. One example can be seen in Patent Document 1. The paper box disclosed in Patent Document 1 covers the upper surface with a double-spread left upper surface plate and a right upper surface plate so that the entire upper surface can be opened.
JP 2005-186882 A (page 8-9 [0030]-[0034], FIG. 3)

  In the paper box described in Patent Document 1, a locking opening is provided in the left upper plate, and the convex curved sides of the right upper plate are inserted into the locking opening and locked, thereby keeping both upper plates closed. However, with this method, there is a problem that dust or the like enters the inside of the paper box from the locking opening and that the design of the paper box is impaired due to the presence of the locking opening.

  The present invention has been made in view of the above points. The upper surface of the present invention can be greatly opened, and it is easy to maintain the lid once opened, and the presence of the lid maintenance means does not impair the design. The purpose is to provide a paper box.

To accomplish the above object, the double doors of the lid portion blank sheet on the upper surface of the box body formed by attaching Okoshihako and glue provided on the rear surface of both the lid portion, from the opposite side edges of the lid portion The folded flap forms a pocket into which the tip of the other lid portion can be inserted, and the pocket flap is formed with an embossing projecting toward the lid portion, and the lid inserted into the pocket. The tip of the part has an arc-shaped convex part, and the lid part is a paper box in which no emboss is formed .

According to the present invention, it is possible to open wide the upper surface by double doors of the lid portion, after it is convenient for or exhibiting or the content was taken out, pockets of the other lid portion formed on the back surface of one of the lid portion By inserting the tip, it is possible to provide a paper box that can maintain a closed state even after it is once opened. Unlike the opening, the pocket on the back of the lid does not allow dust or the like to enter the inside of the paper box, and does not impair the design of the paper box. In addition, even if the two lid portions are stacked so that either one is on top, the leading end of the lid portion can be inserted into the pocket, and insertion does not fail. In addition, since the pocket entrance is always opened by the embossing formed in the pocket flap, the lid portion can be smoothly received.

  Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 1 is a perspective view of a paper box in a closed state, FIG. 2 is a perspective view of a paper box in an open state, FIG. 3 is a sectional view of the paper box, and FIG. 4 is a development view of a blank sheet.

  The paper box 1 shown in FIG. 1 is formed by opening the blank sheet 10 shown in FIG. 4 and pasting a predetermined portion with hot air, hot melt adhesive, cold glue adhesive, or the like. The blank sheet 10 is formed by punching a printed paper sheet, whose material characteristics such as rigidity, water resistance, oil resistance, and water repellency are adjusted according to the article to be accommodated, into a predetermined shape, and inserting a fold line (represented by a dotted line). It consists of the following parts.

  First, there is a bottom portion 11. The bottom portion 11 has a rectangular shape, and a rectangular front side portion 12 and a rear side portion 13 are connected to both long sides. The front side portion 12 is the front surface of the paper box 1, and the rear side portion 13 is the back surface of the paper box 1. An inner side portion 15 is connected to the front side portion 12 through a narrow top surface portion 14, and a glue tab 16 is connected to the inner side portion 15. Similarly, an inner side portion 18 is connected to the rear side portion 13 through a narrow top surface portion 17, and a glue tab 19 is connected to the inner side portion 18. Further, side flaps 20L and 20R are connected to both short sides of the front side portion 12, and side flaps 21L and 21R are connected to both short sides of the rear side portion 13.

  A left side portion 22 and a right side portion 23 are connected to both short sides of the bottom portion 11. A left lid portion 24 is connected to the left side portion 22, and a right lid portion 25 is connected to the right side portion 23. Each of the left lid portion 24 and the right lid portion 25 has an arcuate convex portion at the tip (free end). Pocket flaps 26 and 27 are connected to both side edges of the left lid part 24 and the right lid part 25 (edges parallel to the long side of the bottom part 11).

  The procedure for using the blank sheet 10 as the paper box 1 is as follows. First, in the left lid portion 24 and the right lid portion 25, the pocket flaps 26 and 27 are folded toward the back side of the lid portion from both side edges of the lid portion. In FIG. 4, the pocket flaps 26 and 27 after folding are indicated by two-dot chain lines. The left lid portion 24 and the pocket flap 26 are pasted, and the right lid portion 25 and the pocket flap 27 are pasted. Due to the formation of the pocket portion, the glued portion is partial. That is, in the pocket flap 26, the region on the right side of the boundary line 28 indicated by the alternate long and two short dashes line is an object to be glued, and in the pocket flap 27, the region on the left side of the boundary line 29 indicated by the two-dot chain line is Become. The portion that is not glued becomes a pocket 30 in the left lid portion 24 and a pocket 31 in the right lid portion 25 (see FIG. 3).

  After forming the pockets 30 and 31 as described above, the front side portion 12 and the rear side portion 13 are raised. That is, the fold line between the bottom portion 11 and the front side portion 12, the fold line between the front side portion 12 and the top surface portion 14, and the fold line between the top surface portion 14 and the inner side portion 15 are folded inwardly. After the folding line between the portion 15 and the glue tab 16 is folded outward and the glue tab 16 is glued to the bottom portion 11, the wall portion having a thickness corresponding to the width of the top surface portion 14 becomes the bottom portion 11. Stand up on the top. Similarly, a wall portion including the rear side portion 13, the top surface portion 17, the inner side portion 18, and the glue tab 19 is raised on the bottom 11.

  After raising the front side portion 12 and the rear side portion 13 as described above, the side flaps 20L, 20R, 21L, and 21R are bent inward. If the left side part 22 and the right side part 23 are bent to the outside, the outer surfaces of the side flaps 20L and 21L and the inner surface of the left side part 22, the outer surfaces of the side flaps 20R and 21R, and the inner surface of the right side part 23 are respectively attached The main body of the paper box 1 whose upper surface is opened is completed.

  The article of contents is put into the main body of the completed paper box 1, and the upper surface opening is closed by the left lid portion 24 and the right lid portion 25. When the left lid portion 24 and the right lid portion 25 are in the closed state, the arcuate convex portions at the ends overlap each other. When overlapping occurs, the arc-shaped convex portion of the lid portion on the lower side is inserted into the pocket of the lid portion on the upper side, and the closed state is maintained. FIG. 3 shows a state in which the arc-shaped convex portion of the right lid portion 25 is inserted into the pocket 30 of the left lid portion 24.

  When the arc-shaped convex portion of the left lid portion 34 or the right lid portion 25 is inserted into the other party's pocket, it is easy to work if the pocket entrance is open. Therefore, the following is recommended. That is, embosses that are convex toward the lid portion are formed on the pocket flaps 26 and 27. The place is the place near the entrance among the pockets 30 and 31. In this way, the entrances of the pockets 30 and 31 are always open, and the arc-shaped convex portion of the lid portion can be smoothly received.

  In the state where the article is put in as described above and the left and right lid portions 24 and 25 are closed, the paper box 1 is further packaged with a synthetic resin film or the like to obtain a finished form as a product.

  If the packaging of the paper box 1 is removed, the inside of the paper box 1 can be exposed by double-opening the left lid part 24 and the right lid part 25. Since the upper surface of the paper box 1 is greatly opened, it is easy to take out articles and it is easy to see the inside even if it is displayed as it is. Further, since the left and right lid portions 24 and 25 have a double structure by folding the pocket flaps 26 and 27, the rigidity is increased and the opening and closing is easy. In addition, when opening the left lid portion 24, the folded portion of the pocket flap 26 is opened, and when opening the right lid portion 25, the folded portion of the pocket flap 27 is opened with a finger, and the touch is good. There is little risk of cutting the skin of the finger at the edge of the lid.

  If the double door opening of the left lid portion 24 and the right lid portion 25 is closed, the paper box 1 can be placed in the closed state again. At this time, no matter which of the left lid portion 24 and the right lid portion 25 are stacked, the tip of one lid portion is inserted into the pocket of the other lid portion, and the insertion does not fail. .

  Although one embodiment of the present invention has been described above, various modifications can be made without departing from the spirit of the present invention.

  The present invention is widely applicable to paper boxes for relatively small articles.
