In this specification, the substantially trapezoidal shape includes a rectangular shape in which a pair of opposite sides (the opposite sides mean an upper base and a lower base) are parallel and the lower base is longer than the upper base. In the present specification, the upper base includes a slightly curved side in addition to a straight side.
Preferably, the upper wall 5 has an acute angle between the angle formed by one hypotenuse and the lower base and the angle formed by the other hypotenuse and the lower base (two inner angles formed on both sides of the lower base). It is formed in a trapezoid shape.
More preferably, the upper surface wall 5 is formed in an isosceles trapezoidal shape as shown in FIG.
In the present specification, the isosceles trapezoidal shape means a trapezoid in which the angle formed by one oblique side and the lower base and the angle formed by the other oblique side and the lower base are the same acute angles.
The acute angle is preferably 20 ° to 60 °, and more preferably 25 ° to 50 °.

The substantially trapezoidal upper surface wall 5 is arranged with its upper base facing the back wall 3 side and its lower base facing the front wall 2 side.
The top wall 5 are preferably disposed toward the upper base to the central portion in the rear wall 3. By this way the upper surface wall 5 is disposed, the rear wall 3 is a circular arc surface shape that bulges to the most outer central portion inside of that. Therefore, it is possible to hold the article 10 to the central portion in the rear wall 3.

Specifically, upper base of the top wall 5 is provided continuously in the central portion in the upper side of the back wall 3 through a fifth folding border 5a. The upper surface wall 5 can be fitted to or removed from the upper opening of the cylindrical wall 4 by bending the upper surface wall 5 at the fifth crease line 5a formed on the upper base.
In addition, a first flap piece 71 is connected to one oblique side of the upper surface wall 5 via a sixth crease line 6a. A second flap piece 72 is connected to the other oblique side of the top wall 5 via a seventh crease line 7a. The first flap piece 71 and the second flap piece 72 can be bent via the respective folding ruled lines 6 a and 7 a formed on the oblique sides of the upper surface wall 5. The first flap piece 71 and the second flap piece 72 are formed, for example, in a triangular shape (preferably an isosceles triangle shape such as a substantially right-angled isosceles triangle shape) with the hypotenuse of the top wall 5 as a base.

The first flap piece 71 and the second flap piece 72 are inserted into the inner surface side of the arc-shaped back wall 3 when the upper surface wall 5 is fitted into the upper opening of the cylindrical wall 4. The inserted first flap piece 71 and second flap piece 72 are partially in contact with the inner surface of the back wall 3.
The back wall 3 is reinforced from the inside by inserting the first flap piece 71 and the second flap piece 72 into the inner surface side of the back wall 3. Accordingly, the first flap piece 71 and the second flap piece 72 have a function of maintaining the arc surface shape of the back wall 3. The first flap piece 71 and the second flap piece 72 also have a function of closing the gap between the oblique side of the top wall 5 and the back wall 3.

As shown in FIG. 8, the third flap piece 73 of the present embodiment has a base portion 731 having a width substantially the same as the width of the lower bottom of the upper surface wall 5, and extends narrowly from the base portion 731 toward the distal end side. It is installed. Therefore, the edge of the third flap piece 73 is formed in a substantially arc shape in plan view. In addition, a hole 733 is punched and formed in the surface of the third flap piece 73.

The third flap piece 73 is inserted into the inner surface side of the front wall 2 when the upper surface wall 5 is fitted into the upper opening of the cylindrical wall 4. Since the third flap piece 73 is bent at the lower bottom of the top wall 5, the straight shape of the bottom floor of the top wall 5 is maintained (the rigidity of the bottom floor of the top wall 5 is increased).
Of the inserted third flap piece 73, the base portion 731 located in the vicinity of the eighth crease line 8 a is substantially parallel to the inner surface of the front wall 2 and is close to the inner surface of the front wall 2. Since the base portion 731 of the bent third flap piece 73 is inserted in parallel to the inner surface of the front wall 2, the flat surface shape of the front wall 2 can be maintained.

  On the other hand, the other portion 732 of the inserted third flap piece 73 (the other portion means a portion of the third flap piece 73 other than the base portion 731) is inside the hole 733 of the third flap piece 73. In a state where the article 10 is fitted, the article 10 is lowered from the front wall 2 side to the back wall 3 side and extends in an inclined manner. Since the end edge of the third flap piece 73 is formed in an arc shape, the end edge of the other portion 732 of the third flap piece 73 is in contact with or close to the inner surface of the back wall 3. Accordingly, the other portion 732 of the third flap piece 73 serves to maintain the arcuate surface shape of the back wall 3.

Furthermore, the central portion in the lower base of the upper wall 5, so as to protrude into the hole 733, the knob portion 79 is extended. The knob 79 is continuously provided via an eighth fold ruled line 8a formed on the lower bottom. The knob 79 and the third flap piece 73 can be bent independently of each other.
The knob 79 protrudes upward when the upper wall 5 is fitted into the upper opening of the cylindrical wall 4. As will be described later, the knob 79 is used when the top wall 5 is opened.

In addition, a pair of incision lines 51 for insertion are formed at predetermined intervals in a continuous portion (on the lower bottom) between the third flap piece 73 and the upper surface wall 5.
This engraving cut line 51 is a portion into which the engaging portion 84 of the header 8 is inserted.

Next, the cylindrical wall 4 is provided with a header 8 protruding upward. The header 8 is formed, for example, by folding back a header piece 81 connected to the upper side of the front wall 2.
Specifically, the header piece 81 has a width substantially the same as the width of the front wall 2 and extends integrally from the upper side of the front wall 2. A ninth crease line 9 a is formed in the center of the header piece 81 in parallel with the width direction of the front wall 2. The header piece 81 is partitioned into an upper region 82 and a lower region 83 having substantially the same size with respect to the ninth crease line 9a. Furthermore, a pair of engaging portions 84 project from the upper side of the header piece 81 (upper region 82) at a predetermined interval in the width direction. In addition, a suspension hole 85 is formed in the plane of the header piece 81 at a line symmetrical position with the ninth crease line 9a interposed therebetween.

  The header 8 that protrudes above the front wall 2 is formed by folding the header piece 81 along the ninth crease line 9 a and overlapping the upper region 82 and the lower region 83. By inserting the folded engaging portion 84 of the header piece 81 into the engaging cut line 51 of the upper surface wall 5 fitted in the upper opening of the cylindrical wall 4, it is possible to prevent the header piece 81 from opening and It is possible to prevent the wall 5 from being carelessly detached from the upper opening.

Further, in order to close the lower opening of the cylindrical wall 4, a lower surface wall 6 is fitted in the lower opening.
The lower wall 6 is formed in a substantially trapezoidal shape in plan view. The lower base of the substantially trapezoidal lower wall 6 is preferably formed to have a length substantially the same as the width of the front wall 2.
Preferably, the lower wall 6 is formed in a trapezoidal shape in which the angle formed by one oblique side and the lower base and the angle formed by the other oblique side and the lower base are both acute angles, and more preferably, the lower wall 6 It is formed in the shape of an isosceles trapezoid.
The acute angle is preferably 20 ° to 60 °, and more preferably 25 ° to 50 °.
In the present embodiment, the planar view shape of the lower surface wall 6 is formed to be substantially the same as the upper surface wall 5.

The substantially trapezoidal lower surface wall 6 is arranged with its upper base facing the back wall 3 side and its lower base facing the front wall 2 side.
Lower wall 6 preferably disposed toward the upper base to the central portion in the rear wall 3. By this way the lower wall 6 are arranged, rear wall 3, an arcuate surface shape swollen to the most outer central portion inside of that. Therefore, it is possible to hold the article 10 to the central portion in the rear wall 3.

Specifically, the lower bottom of the lower wall 6 is connected to the lower side of the front wall 2 via a tenth crease line 10a. The lower wall 6 can be fitted to or removed from the lower opening of the cylindrical wall 4 by bending the lower wall 6 at the tenth crease line 10a formed on the lower bottom.
Further, a fourth flap piece 74 is connected to one oblique side of the lower wall 6 via an eleventh crease line 11a. A fifth flap piece 75 is connected to the other oblique side of the lower wall 6 via a twelfth crease line 12a. The fourth flap piece 74 and the fifth flap piece 75 can be bent via the respective folding ruled lines 11 a and 12 a formed on the oblique sides of the lower surface wall 6. For example, the fourth flap piece 74 and the fifth flap piece 75 are formed in a triangular shape (preferably an isosceles triangle shape such as a substantially right-angled isosceles triangle shape) with the hypotenuse of the lower surface wall 6 as a base.

The fourth flap piece 74 and the fifth flap piece 75 are inserted into the inner surface side of the arc-shaped back wall 3 when the lower surface wall 6 is fitted into the lower opening of the cylindrical wall 4. The inserted fourth flap piece 74 and fifth flap piece 75 are partially in contact with the inner surface of the back wall 3.
The back wall 3 is reinforced from the inside by inserting the fourth flap piece 74 and the fifth flap piece 75 into the inner surface side of the back wall 3. Accordingly, the fourth flap piece 74 and the fifth flap piece 75 have a function of maintaining the arc surface shape of the back wall 3. Further, the fourth flap piece 74 and the fifth flap piece 75 also have a function of closing the gap between the oblique side of the lower surface wall 6 and the back wall 3.

Furthermore, in order to seal the fitted lower wall 6 downwardly opening, the central portion in the lower side of the rear wall 3, stopping piece 9 is provided continuously via a thirteenth folding border 13a. The stopper piece 9 can be bent at a thirteenth fold ruled line 13 a formed on the lower side of the back wall 3. Further, a fourteenth crease line 14a is formed in the surface of the stopper piece 9 in parallel with the thirteenth crease line 13a. The stopper piece 9 is divided into an upper region 91 and a lower region 92 with reference to the fourteenth crease line 14a.
The stopper piece 9 is formed, for example, in a substantially rectangular shape in plan view. But the stop piece 9 is not limited to this shape, You may form in another shape.

  The stopper piece 9 is folded back at the fourteenth crease line 14a, and the upper region 91 and the lower region 92 are overlapped. By bonding the lower region 92 to the outer surface of the lower wall 6, the lower wall 6 is sealed by the stopper piece 9. Therefore, even if the article 10 is stored in the cylindrical wall 4, there is no possibility that the lower wall 6 is detached from the cylindrical wall 4.

  As shown in FIG. 3, the stopper piece 9 is preferably bonded to the outer surface of the lower wall 6 so that both corners 93, 93 of the stopper piece 9 slightly protrude from both oblique sides of the lower wall 6. Since the corner portion 93 of the stopper piece 9 projects in this way, the end edge of the corner portion 93 contacts the inner surface of the back wall 3, so that the arc surface shape of the back wall 3 can be maintained.

The front wall 2, the back wall 3, the top wall 5, the bottom wall 6 and / or the header 8 may be subjected to desired printing as necessary.
In the case where the packaging case 1 is formed using the transparent sheet material 11, it is possible to see through the front wall 2 the printed display applied to the back wall 3 by performing desired printing on the back wall 3. Thus, if the front wall 2 is made transparent and printing is performed on the back wall 3 that is a circular arc surface, the printed display of the back wall 3 seen through the front wall 2 can be seen three-dimensionally.

Next, the assembly procedure of the packaging case 1 will be described.
By bonding the adhesive margin piece 41 to the other side of the back wall 3 while bending the sheet material 11 cut into a shape as shown in the developed view at the first to fourth crease lines 1a, 2a, 3a, 4a The cylindrical wall 4 is formed.
Next, the fourth flap piece 74 and the fifth flap piece 75 are bent inward at the eleventh crease line 11a and the twelfth crease line 12a, and the lower wall 6 is bent inward at the tenth crease line 10a. The lower wall 6 is fitted into the lower opening of the cylindrical wall 4 while the 74 and the fifth flap pieces 75 are inserted into the cylindrical wall 4. The inserted fourth flap piece 74 and fifth flap piece 75 are urged toward the inner surface side of the back wall 3 by bending repulsion and partially contact the inner surface of the back wall 3.

On the other hand, the stopper piece 9 is folded back at the fourteenth crease line 14a, and the stopper piece 9 is bent at the thirteenth crease line 13a, and an adhesive is applied to the lower region 92 of the stopper piece 9, and this is adhered to the lower surface wall 6.
In this way, as shown in FIG. 9, a packaging case 1 is obtained in which the lower opening of the cylindrical wall 4 is closed by the lower wall 6 and the upper opening of the cylindrical wall 4 is opened. The article 10 is inserted into the cylindrical wall 4 from the upper opening.

Next, as shown in FIGS. 9 and 10, the first flap piece 71, the second flap piece 72, and the third flap piece 73 are placed inside the sixth fold ruled line 6 a, the seventh fold ruled line 7 a, and the eighth fold ruled line 8 a. The upper surface wall 5 is bent inward at the fifth crease line 5a, and the upper surface wall 5 is inserted while inserting the first flap piece 71, the second flap piece 72 and the third flap piece 73 into the cylindrical wall 4. It fits in the upper opening of the cylindrical wall 4. When inserting the third flap piece 73, the third flap piece 73 is inclined so that the article 10 fits in the hole 733 of the third flap piece 73, and the third flap piece 73 is placed on the back side (rear wall of the article 10). (3 side).
The inserted first flap piece 71 and second flap piece 72 are urged toward the inner surface side of the back wall 3 by bending repulsion and partially contact the inner surface of the back wall 3. Further, the base portion 731 of the inserted third flap piece 73 is close to the inner surface of the front wall 2, while the other portion 732 of the third flap piece 73 is lowered from the front wall 2 side to the back wall 3 side. It extends in an inclined shape, and its edge touches or is close to the inner surface of the back wall 3.
In addition, when fitting the upper surface wall 5, the knob | pick part 79 is not inserted in the inside of the cylindrical wall 4, but is made to protrude outside.

Next, other embodiment of the packaging case 1 of this invention is shown.
Hereinafter, although other embodiment is described, about the structure and effect similar to the said embodiment, the description is abbreviate | omitted and a term and a figure number may be used.
In the above embodiment, the lower wall 6 is sealed by bonding the bent stopper piece 9, but the stopper piece 9 may not be used. For example, the lower surface wall 6 may be sealed by applying an adhesive tape (or an adhesive label) across the outer surface of the lower surface wall 6 and the outer surface of the cylindrical wall 4.

  Moreover, in the said embodiment, although the lower bottom of the lower surface wall 6 is connected with the lower side of the front wall 2, for example, the lower bottom of the lower surface wall 6 is not connected with the front wall 2, The upper bottom of the wall 6 may be connected to the lower side of the back wall 3. When the upper bottom of the lower wall 6 is connected to the rear wall 3, a stopper piece as shown in the above embodiment is provided on the lower side of the front wall 2, or by attaching an adhesive tape or the like, the lower wall 6 can be sealed. Moreover, the lower surface wall 6 can also be sealed by providing the flap piece inserted in the inner surface side of the front wall 2 in the lower bottom of a lower surface wall.

  Furthermore, in the said embodiment, although the hole part 733 is formed in the surface of the 3rd flap piece 73 and the knob | pick part 79 protrudes in this hole part 733, the 3rd flap piece 73 is, for example, As shown in the development view of FIG. 13, it may extend from the entire bottom bottom of the top wall 5. As shown in FIG. 14, the third flap piece 73 is inserted into the cylindrical wall 4 so that the entire third flap piece 73 is parallel to and in contact with the inner surface of the front wall 2. As described above, the third flap piece 73 extends over the entire bottom of the top wall 5, so that the rigidity of the bottom of the top wall 5 is extremely high, and the flat surface shape of the front wall 2 can be further maintained.

Moreover, in the said embodiment, although the upper surface wall 5 has the upper base of the upper surface wall 5 connected with the upper side of the back surface wall 3, it is not limited to this, The upper base and both oblique sides of the upper surface wall 5 are the back wall. 3, and the bottom of the top wall 5 may be connected to the top wall 2.
Furthermore, in another embodiment, as shown in FIG. 15, the upper bottom and both oblique sides of the top wall 5 are connected to the upper side of the back wall 3, and the third flap piece 73 is connected to the bottom of the top wall 5. It may be provided. Specifically, upper base of the top wall 5 is provided continuously in the central portion in the upper side of the back wall 3 through a fifth folding border 5a. The upper base is a slightly curved side (substantially straight side). Further, both oblique sides of the upper surface wall 5 are connected to the upper side of the rear wall 3 via the 15th crease lines 15a and 15a. Further, a pair of sixteenth crease lines 16 a, 16 a extending from both ends of the upper bottom of the top wall 5 to both sides of the back wall 3 are formed in the upper surface of the back wall 3. The sixteenth crease lines 16a and 16a are formed such that the angle formed by the sixteenth crease line 16a and the fifteenth crease line 15a is an acute angle (for example, 20 degrees to 40 degrees). Accordingly, the upper portion of the back wall 3 has the folded portions 31, 31 that are triangular in plan view and are partitioned by the fifteenth crease line 15a and the sixteenth crease line 16a. Further, similarly to the above embodiment, the third flap piece 73 having the hole portion 733 is connected to the lower bottom of the top wall 5 via the eighth crease line 8a, and protrudes into the hole portion 733. As shown, a knob 79 is extended.

As shown in FIG. 16, the packaging case 1 of the other embodiment bends the upper surface wall 5 at the fifth crease line 5 a and the fifteenth crease line 15 a, and the triangular folding portions 31, 31 are formed on the back wall 3. The folded portion 31 is folded at the 16th crease line 16a so as to contact the inner surface. The palm-folding means that the folding portion 31 (upper portion of the back wall 3) folded at the 16th fold ruled line 16a is folded so as to face the back wall 3.
At the same time, the upper surface wall 5 is fitted into the upper opening of the cylindrical wall 4 while the third flap piece 73 is inserted into the cylindrical wall 4 as in the above embodiment. Similarly to the above embodiment, the third flap piece 73 is inserted so that the article 10 fits in the hole portion 733, and the knob 79 is not inserted into the cylindrical wall 4 but protrudes outward. .
Thus, the packaging case 1 in which the upper opening of the cylindrical wall 4 is blocked by the upper surface wall 5 can be configured. The packaging case 1 can be lifted by holding the knob 79 to remove the top wall 5 and open the upper opening.
The packaging case 1 according to the other embodiment can easily close the upper opening of the cylindrical wall 4 with the upper surface wall 5. Furthermore, since the packaging case 1 has the upper bottom and both oblique sides of the upper surface wall 5 connected to the upper side of the back wall 3, the arcuate surface shape of the back wall 3 can be maintained well. In addition, in the packaging case 1, the folding portion 31 connected to the top wall 3 is folded at the 16th fold line 16a, and the folding portion 31 is in contact with (or close to) the inner surface of the back wall 5. Therefore, it becomes difficult for the upper surface wall 5 to come off carelessly.

Furthermore, in the said embodiment, although the back wall 3 is made into the circular arc surface substantially, the back wall 3 may be made into the polygonal surface. The polygonal surface has a shape in which an obtuse angle portion (the obtuse angle portion is preferably 120 degrees or more and less than 180 degrees) is formed on a part of the arc surface. Even with the polygonal back wall 3, the article can be held at a predetermined position on the cylindrical wall 4.
The polygonal surface back wall 3 can be formed by forming one or a plurality of crease lines extending in the vertical direction in the surface of the back wall 3. For example, a crease line (in this case, two crease lines extending in the vertical direction in the plane of the back wall 3 so as to connect both ends of the upper bottom of the upper surface wall 5 and both ends of the upper bottom of the lower surface wall 6. ), The back wall 3 may be a polygonal surface. Further, for example, the back wall 3 may be a polygonal surface by forming three or more crease lines extending in the vertical direction at predetermined intervals in the surface of the back wall 3.
