  Among the above-mentioned cartons, the type that opens a part of the top surface has the advantage that it can be opened widely and the contents can be easily taken out, but it keeps the opened state if the lid is not held by hand. It is not possible to take out the contents while it is placed on a table. And even if it is in the closed state, the knob is simply inserted into the slit of the side plate and stopped. Therefore, if it is dropped, there is a problem that the lid opens and the contents spill out. In addition, the zippered jagged edges remain in the opened portion, which causes a problem that it does not look good.

  The present invention has been made in view of such problems, and the purpose of the present invention is to maintain an opened state, and even if the lid is closed, the contents overflow. In addition, the object is to provide a carton that does not have the unpleasant appearance as in the case of using a zipper, and further has a playful feeling for opening and closing operations.

  In order to achieve the above object, the carton of the present invention is a carton produced by assembling a single blank, and the front panel and the back panel are connected to each other through a broken line before and after the bottom panel. The rear panel has an upper panel connected to the upper side of the rear panel via a fold line, and the front panel has a standing panel that can be bent back and forth with a narrow width through a breakable adhesive panel. A slide panel is connected to the tip of the standing panel via a fold line, and a breakable removal region is formed on the top panel to form an opening for exposing the standing panel in the center, and the tip The adhesive panel is provided with a through hole at a position where it overlaps with the knob area of the top panel, and the slide panel is folded inward with respect to the standing panel. In this state, the top portion of the top panel is bonded to the adhesive panel, and the body portion is formed by pasting the top panel to the back side of the slide panel through the hole in the adhesive panel. One of the body portions is closed, the contents are charged, and the other is closed.

  The carton having the above structure is formed by opening the opening for exposing the standing panel by breaking and removing the removal region in the center of the top panel, and then the gripping region on the top panel and the slide panel adhered thereto When the front panel side is picked and pulled, the front panel and the adhesive panel are broken and separated, and the slide panel can be pulled out from the separated gap. When the slide panel is pulled as it is, the standing panel is bent at the opening in the top panel and opened while rising, and the opened state is maintained after opening. Further, when the slide panel is pushed in, the upright panel can fall down and the opening can be closed.

  In the carton of the present invention, when the slide panel is pulled, the opening of the top panel is opened with the upright panel standing up, so the opened state can be maintained without having to hold the lid by hand after opening. Can be maintained. Also, if the slide panel is closed after opening, the opening will not open unless the slide panel is pulled, so that the contents will not overflow even if it is dropped. Moreover, since the opening means by a zipper like the past is not provided, it can prevent that the appearance by opening becomes worse. In addition, since the standing panel provided at the opening rises as the slide panel is opened by pulling out, it is possible to provide something that is playful when opening and closing.

  Next, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a perspective view showing an example of a carton according to the present invention, and FIG. 2 is a development view of a blank for assembling the carton shown in FIG.

  The blank of FIG. 2 is a single piece formed by punching paperboard for paper containers. As shown in the figure, the front panel 2 and the back panel 3 are connected to each other before and after the bottom panel 1 via folding lines. The upper surface panel 4 is connected to the upper side of the rear panel 3 via a fold line, and the front panel 2 is front and rear in a narrow width via an adhesive panel 5 that is short in the longitudinal direction and breakable. An upright panel 6 that can be bent is provided continuously, and a slide panel 7 is provided at the tip of the upright panel 6 via a broken line. The top panel 4 has a breakable removal region 4a that forms a rectangular opening for exposing the standing panel 5 at the center, and a semicircular knob region 4b that can be broken at the tip. The adhesive panel 5 is provided with a semicircular through hole 5a at a position overlapping the knob region 4b of the top panel 4.

  The adhesive panel 5 is connected to the front panel 2 by an arc-shaped cut line a that slightly protrudes toward the front panel in the middle, and a break line b on both sides thereof, and is located near the center of the cut line a. However, a part of the hole 5a is formed in a semicircular shape. Here, the combined length of the adhesive panel 5 and the upright panel 6 is substantially the same as that of the slide panel 7. When the slide panel 7 is folded back with respect to the upright panel 5, it overlaps or slightly protrudes from the cut line a. As described above, the tip of the slide panel 7 has an outwardly arcuate shape.

  Further, the boundary line c between the adhesive panel 5 and the standing panel 6 and the boundary line d between the standing panel 5 and the slide panel 7 are each formed of a lead ruled with a cut in the middle for easy folding. In the illustrated example, the standing panel 5 is formed with a cut line f projecting in a large semicircular shape toward the slide panel in the middle of the central bending line e.

  The rectangular removal region 4a at the center of the top panel 4 is partitioned by a cutting line g having a plurality of jumpers in the middle, and the semicircular picking region 4b at the tip has a plurality of jumpers in the middle. It is demarcated by a cut line h. Further, a pressing portion 4c is defined by a semicircular cut line i with a hook at the center of the removal region 4a on the back panel side.

  In addition, side inner panels 8 are connected to the left and right sides of the bottom panel 1 via fold lines, respectively, and side side outer panels 9 are connected to the left and right sides of the upper surface outer panel 4 via fold lines, respectively. Folding flaps 10 are continuously provided via folding lines, and folding flaps 11 are provided on the left and right sides of the back panel 3 via folding lines. Further, guide pieces 12 having convex portions 12a on the upright panel 6 side are provided on the left and right sides of the slide panel 7 through fold lines, respectively.

  The side outer panels 9 on the left and right sides of the top panel 4 are substantially the same as the height of the box (the height of the back panel 3), but the side inner panels 8 on the left and right sides of the bottom panel 1 are bent inside. Therefore, it is slightly lower than the height of the box, and an arcuate cutout 8a is formed on the side of the front panel.

  In order to assemble the above blank, first, the sack is applied. Specifically, in a state where the slide panel 7 is folded inward with respect to the standing panel 6, the front panel side is folded back with respect to the bottom panel 1, and then the top panel 4 is folded back with respect to the back panel 3 to form an adhesive panel. 5, the top end portion of the upper panel 4 is bonded together, and the knob region 4 b of the upper panel 4 is bonded to the back side of the slide panel 7 through the through hole 5 a of the adhesive panel 5.

  Then, in the filling step, the sack-attached blank is raised in a square tube shape, one of the body portions is closed, the contents are charged, and the other is closed, thereby assembling the carton shown in FIG. The closing order is the same for both. That is, the folding flaps 10 and 11 are first folded, and then the side inner panel 8 is folded so as to cover the folding flaps 10 and 11. Next, the side outer panel 9 is bent from above the guide piece 12 so that the guide piece 12 is bent, and the tip of the bent side outer panel 9 is bonded to the side inner panel 8. At this time, a part of the folded flap 10 is exposed at the arc-shaped notch 8a. The side outer panel 9 is bonded to the exposed portion with the adhesive G. Thereby, the front panel 2 is fixed to the side surface of the carton via the folding flap 10. Moreover, by assembling in this way, the front end edge of the slide panel 7 is slightly protruded from the middle gap between the front panel 2 and the adhesive panel 5.

  In order to open the carton of FIG. 1, first, the removal region 4a at the center of the upper panel 4 is broken and removed, thereby forming an opening for exposing the upright panel 6 as shown in FIG. . That is, the pressing part 4c of the removal area 4a is pushed and broken with a fingertip, and the removal area 4b is broken and removed by using this as a cut.

  Subsequently, when the picking region 4b in the top panel 4 and the front panel side of the slide panel 7 adhered thereto are picked and pulled, the front panel 2 and the adhesive panel 5 are broken and separated, and the separated gap Thus, the slide panel 7 can be pulled out. At this time, since the leading edge of the slide panel 7 protrudes from the middle gap between the front panel 2 and the adhesive panel 5, it can be grasped and gripped with a fingertip. When the slide panel 7 is pulled as it is, as shown in FIG. 4, the upright panel 6 is bent at the opening of the upper panel 4 and is opened while being raised, and the opened state is maintained after opening. Moreover, when the slide panel 7 is pushed in from the unsealed state of FIG. 4, the upright panel 6 falls down and the opening can be closed as before.

  In the above carton, since the guide piece 12 is provided on the slide panel 7 and the convex portion 12a is provided on the guide piece 12, when the slide panel 7 is pulled, the convex portion 12a is formed between the folded flap 10 and the side outer panel 9. The process proceeds to the position of the adhesive G, but cannot be pulled out any further. Further, since the front panel 2 is bonded to the side surface outer panel 9 at the notch 8a of the side surface inner panel 8, the box shape does not collapse even if the front panel 2 and the adhesive panel 5 are cut at the time of opening. . Further, when the slide panel 7 is pushed in, it can be smoothly slid to the closed position by the guide pieces 12 on both sides.

  Thus, when the carton of FIG. 1 is opened by pulling the slide panel 7, the opened state is maintained even if it is left as it is. Further, when the slide panel 7 is closed after opening, the opening is not opened unless the slide panel 7 is pulled, so that the contents do not overflow even if the slide panel 7 is dropped.

  The embodiment of the present invention has been described in detail above. However, the carton according to the present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention. It is natural that there is.

It is a perspective view which shows an example of the carton concerning this invention. It is an expanded view of the blank which assembles the carton shown in FIG. It is a perspective view which shows the state which formed the opening in the upper surface panel in order to open the carton shown in FIG. It is a perspective view shown in the state which opened the carton shown in FIG.
