  The above-described double-structured packaging container is designed to pull out the inner box and take out the contents. Therefore, when the whole is made into a slender shape, for example, granular confectionery is arranged in a row, It is convenient that you can take it out one by one. However, when the inside box is pulled out and tilted to take out the contents, the contents come out one after another so as to flow, and it is difficult to reliably take out the contents one by one.

  The present invention has been made in view of the above problems, and the object of the present invention is to provide a cylindrical sleeve having open front and rear ends and a tray-like medium that is slidably inserted into the sleeve. An object of the present invention is to provide a packaging container having a double structure composed of a box and capable of reliably taking out the contents one by one.

A packaging container according to the present invention is a double-structured packaging container comprising a cylindrical sleeve open at both front and rear ends and a tray-like inner box that is slidably inserted into the sleeve. The front part is provided with a rotating part that bends downward at the fold line provided on the bottom plate, and the rotating part is provided with a blocking plate that extends rearward on the bottom plate beyond the fold line. When the tip of the blocking plate protrudes rearward and the protruding portion is not attached to the bottom plate, when the rotating part of the inner box is pulled forward from the sleeve and bent downward at the folding line The tip of the blocking plate rises simultaneously with the bending of the rotating part .

  According to the present invention, the rotating portion of the inner box is pulled forward from the sleeve, and is bent downward at the folding line to take out the contents. The rotating portion is bent while one content is placed, and is rotated. The blocking plate rises simultaneously with the bending of the portion, and the rising blocking plate acts to prevent the remaining contents from flowing out.

In such a packaging container, it is preferable that a stopper mechanism is provided for locking the inner box when the middle box is pulled out from the sleeve to the fold line . For example, a stopper mechanism may be formed by a protrusion provided at the rear portion of the inner box and a locking portion provided on the inner surface of the sleeve. With this configuration, only the rotating portion of the inner box can be pulled forward from the sleeve.

  According to the packaging container of the present invention, the stored granular contents can be reliably taken out one by one.

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

  FIG. 1 is a perspective view showing a packaging container according to an embodiment of the present invention in a separated state. As shown in the figure, this packaging container has a double structure comprising a cylindrical sleeve 10 having both front and rear openings and a tray-like inner box 20 slidably inserted into the sleeve 20.

  FIG. 2 is a development view of a blank for assembling the sleeve 10. This blank is obtained by punching a paperboard into the shape shown in the drawing, and five elongated panels, that is, a bottom outer panel 11, a side panel 12, a top panel 13, a side panel 14, and a bottom inner panel 15 are folded lines a, b, It has a shape that is successively arranged via c and d. The upper part of the figure is the front side, and a notch 15a constituting a locking part for hooking a protrusion (described later) provided on the rear part of the inner box 20 is provided on the rear part of the bottom inner panel 15.

  The procedure for assembling the blank of the sleeve 10 is as follows. First, after turning over so that the back surface faces upward, the bottom inner panel 15 is folded at the fold line d with respect to the side panel 14, and an adhesive is applied to the surface of the bottom inner panel 15. Next, the side panel 12 is valley-folded with respect to the top panel 13 along the fold line b, and the back surface of the bottom outer panel 11 is adhered to the surface of the bottom inner panel 15 to form a sack pasting state. Thereafter, the sleeve 10 is formed in a rectangular tube shape from the sack pasting state, thereby forming a sleeve 10 having both front and rear ends opened as shown in FIG.

  FIG. 3 is a development view of a blank for assembling the inner box 20. This blank is also obtained by punching a paperboard into the shape shown in the figure. The upper portion of the figure is the front side, and an elongated bottom plate 21 having substantially the same length as the sleeve 10 is arranged in the center. 22 is connected through the broken lines a and b.

  A bent portion 21a is defined at the front portion of the bottom plate 21 via a fold line c, and each side plate 22 is provided with a V-shaped notch 23 having both ends of the fold line c of the bottom plate 21 as top portions. Thus, a small side plate 22a is partitioned at the front portion of each side plate 22 in a separated state.

  A front plate 24, an upper plate 25, an intermediate plate 26, and a blocking plate 27 are sequentially arranged in front of the bent portion 21a of the bottom plate 21 via folding lines d, e, f, and g. Further, a flap 28 is connected to each side plate 22 in front of the small side plate 22a via a fold line h, and a folding piece 29 is connected to each side via a fold line i. Here, the width of the front plate 24 is set to be slightly larger than the width of the bottom plate 21.

  A rear plate 30 and a folding plate 31 are successively connected to the rear portion of the bottom plate 21 via folding lines j and k, and a flap 32 is connected to the rear portion of each side plate 22 via folding lines l and m, respectively. Has been. A cut 30a having a shape slightly protruding toward the bottom plate 21 is provided at the center of the broken line j.

  The procedure for assembling the blank of the inner box 20 is as follows. First, after being reversed so that the back surface faces upward, an adhesive is applied to the rear side of the back surface of the blocking plate 27 and the back surface of the bent portion 21a on the front side, and on the back side, the adhesive is applied to the back surface of the folded plate 31. Apply.

  On the front side, each flap 28 is valley-folded with respect to the small side plate 22a at the folding line h, each folding piece 29 is valley-folded with respect to the small side plate 22a at the folding line i, and each small side plate 22a is bent. 21a is folded at fold lines a and b. Next, the blocking plate 27 is valley-folded with respect to the middle plate 26 at the folding line g, the middle plate 26 is folded with respect to the upper plate 25 at the folding line f, and the upper plate 25 is folded with respect to the front plate 24 at the folding line e. Fold the valley. Then, with the blocking plate 27, the middle plate 26, and the upper plate 25 folded as described above, the front plate 24 is valley-folded with respect to the bent portion 21a along the fold line d, and the blocking plate 27 is adhered to the bent portion 21a. . In this case, the front end portion of the blocking plate 27 protrudes from the bent portion 21a by a predetermined length. When the front part is assembled in this way, as shown in FIG. 1, the leading end portion of the blocking plate 27 protrudes backward from the folding line c, and the protruding portion is not attached to the bottom plate 21. Therefore, the front portion of the inner box 20 is provided with a rotating portion A that is bent downward at a folding line c provided on the bottom plate 21, and the rotating portion A is prevented from extending backward on the bottom plate 21 beyond the folding line c. A plate 27 will be provided.

  On the other hand, on the rear side, each flap 32 is valley-folded with respect to the side plate 22 at the folding lines 1 and m, and each side plate 22 is valley-folded with respect to the bottom plate 21 at the folding lines a and b. Subsequently, the rear plate 30 is folded at the fold line j with respect to the bottom plate 21, and the folded plate 31 is folded to the inner side at the fold line k with respect to the rear plate 30, and is attached to the pair of flaps 32. When the rear part is assembled in this manner, the protrusion 30b formed by the cut 30a protrudes on the lower side of the rear plate 30.

  Here, the sizes of the sleeve 10 and the inner box 20 are set so that there is no extra gap between them and the inner box 20 can be smoothly slid relative to the sleeve 10.

  After assembling the sleeve 10 and the inner box 20 as described above, a plurality of granular confectionery items are stored in the inner box 20, and the inner box 20 is inserted into the sleeve 10. After enclosing, the entire outer periphery is packaged with a film to form a sales form.

  When a consumer who has purchased a product at the store takes out the contents, the inner box 20 can be pulled out of the sleeve 10 by peeling the film and then pulling the fingers on both sides of the front plate 24. Then, as shown in FIG. 4, after the bottom plate 21 is pulled out to the fold line c, the rotating portion A is bent downward at the fold line c to take out the contents. While being bent, the blocking plate 27 rises simultaneously with the bending of the rotating portion A, and the rising blocking plate 27 prevents the contents remaining in the inner box 20 from flowing out. In particular, when square contents such as a rectangular parallelepiped are closely lined up, it is easy to take out by folding that the first one is difficult to take out.

  For easy understanding, FIG. 5 shows a state in which the contents N appear one by one. Further, as shown in FIG. 5, the contents N may be easily taken out by making the tip of the top panel 13 into an R shape.

  The inner box 20 is provided with a protrusion 30b at its rear part, and the sleeve 10 is provided with a locking part by a notch 15a on the inner surface thereof, so that the rotating portion A of the inner box 20 is moved forward from the sleeve 10. When it is pulled out, the protrusion 30b is caught by the locking portion and stopped when it is pulled to the broken line c. Therefore, it is possible to reliably take out the contents one by one without pulling out the inner box 20 from the sleeve 10 and spilling the contents. Note that this stopper mechanism is an example. When such a stopper mechanism is necessary, the inner box 20 is locked at a predetermined position when the rotating portion A of the inner box 20 is pulled forward from the sleeve 10. It may be formed as appropriate.
