Description

  The present invention relates to a packaging case that is formed by assembling sheet materials and can be stored in a state where a cylindrical article is held at a predetermined position.

Conventionally, various types of packaging cases in which sheet materials such as synthetic resin sheets are assembled are known.
A typical form of the packaging case is a box shape in which a sheet material is formed in a hollow rectangular parallelepiped shape.
However, when a cylindrical article is stored using the hollow rectangular parallelepiped packaging case, a holding member (core) for preventing the cylindrical article from moving is separately required.

  Moreover, as shown in FIGS. 15 and 16, as a packaging case for storing a cylindrical article, a cylindrical wall 40 having a front wall 20 and a rear wall 30 curved in an arc shape, and an upper opening of the cylindrical wall 40. And a pair of holding pieces that can be bent into the inside of the cylindrical wall 40 by punching out an in-plane center portion of the back wall 30. A packaging case 100 in which the portions 80 and 80 are formed to face each other is known. According to the packaging case 100, the cylindrical article A is sandwiched between the pair of holding piece parts 80, 80 facing each other inside the cylindrical wall 40, so that the cylindrical article is provided at a substantially central portion in the cylindrical wall 40. This can be stored with A held.

However, since the packaging case 100 is punched in the surface of the back wall 30 in order to form the holding piece portions 80, 80, the body portion of the cylindrical article A looks out from the punched portion 30a. Accordingly, there is a problem in that the cylindrical article A rotates because the body part of the article coming out of the portion 30a is likely to come into contact with foreign substances during the distribution of the packaging case 100.
When the article rotates in this way, the design display of the article that is aligned with the front of the packaging case (the surface that the consumer can see at the time of display) cannot be shown to the consumer, and improvements are required. .

  An object of the present invention is to provide a packaging case in which sheet materials are assembled, and capable of storing a cylindrical article in a predetermined position while preventing the cylindrical article from rotating.

  The packaging case of the present invention is formed by assembling sheet materials, and covers a cylindrical wall that houses a cylindrical article, an upper wall that closes an upper opening of the cylindrical wall, and a lower opening of the cylindrical wall. And a bottom wall on which the cylindrical article is placed, and the cylindrical wall is a front wall and a back surface of a circular arc surface or a polygonal surface that is connected to both sides of the front wall via a crease line. And the upper surface wall is formed in a substantially trapezoidal shape, and a hole having an edge close to the upper outer peripheral surface of the cylindrical article to be stored is formed in the surface of the upper surface wall. The urging piece for urging the cylindrical article toward the lower wall extends from a part of the edge of the hole in the center direction.

In the packaging case of the present invention, since the back wall is an arc surface or a polygonal surface, the cylindrical article is held at a predetermined position between the back wall and the front wall. Further, by storing the cylindrical article in the cylindrical wall so that the upper part of the cylindrical article is seen through the hole in the upper surface wall, the edge of the hole is close to the upper outer peripheral surface of the cylindrical article. Therefore, since the cylindrical article is held by the hole, it is possible to prevent the stored cylindrical article from being displaced in the width direction of the cylindrical wall.
Further, since the stored cylindrical article is urged toward the lower wall by the urging piece, the cylindrical article is sandwiched between the lower wall and the urging piece. Therefore, it is possible to prevent the stored cylindrical article from being displaced in the vertical direction, and it is also possible to prevent this from rotating.

  In a preferred packaging case of the present invention, the upper base of the substantially trapezoidal top wall is connected to the substantially central portion of the upper side of the back wall, and both the oblique sides of the top wall and the upper side of the back wall are both A first connecting piece and a second connecting piece are connected to each other via a crease line, the upper surface wall is bent at the upper bottom, and the first and second connection pieces are connected at the crease line. By bending each piece, the upper wall closes the upper opening of the cylindrical wall, and the back wall is reinforced by the first and second connecting pieces.

  The packaging case of the present invention can store the cylindrical article in a predetermined position because the cylindrical article is not easily displaced and rotated without using a separate holding member.

  Hereinafter, preferred embodiments of the present invention will be specifically described with reference to the drawings. In addition, there are cases where the first, second, etc. are added as the prefixes of the terms of each part, but the prefixes are added to distinguish the terms and do not mean the order or superiority of each part. . Moreover, in order to distinguish each wall which comprises a packaging case, it calls a front wall, a back wall, an upper surface wall, and a lower surface wall, but a front, a back surface, an upper surface, and a lower surface do not mean a specific direction.

1 to 5, reference numeral 1 denotes a packaging case formed by assembling sheet materials.
FIG. 6 is a development view of the sheet material forming the packaging case 1.
The packaging case 1 includes a cylindrical wall 4 having a front wall 2 and a back wall 3, an upper wall 5 that closes an upper opening of the cylindrical wall 4, and a lower wall 6 that blocks a lower opening of the cylindrical wall 4. Have.
The packaging case 1 can be self-supporting with the lower wall 6 down.

A cylindrical article 10 is accommodated in the cylindrical wall 4 of the packaging case 1 as illustrated. The accommodated cylindrical article 10 is placed on the lower surface wall 6 with its lower surface in contact with the lower surface wall 6 of the packaging case 1, and the upper surface thereof is biased by the urging piece 8. It is biased to the 6th side. Since the cylindrical article 10 is urged downward by the urging piece 8, the stored cylindrical article 10 is sandwiched between the lower wall 6 and the urging piece 8. Therefore, the stored cylindrical article 10 is not easily displaced in the vertical direction and is difficult to rotate within the cylindrical wall 4.
Since the cylindrical article 10 is urged by the urging piece 8, the distance between the urging piece 8 and the lower wall 6 (the vertical length between the urging piece 8 and the lower wall 6) is stored. It is shorter than the vertical length of the cylindrical article 10. However, if this interval is too short, the cylindrical article 10 may not be accommodated, so the interval is designed in an appropriate range.

  Since the cylindrical wall 4 is a cylindrical body having a flat front wall 2 and an arcuate or polygonal back wall 3, the cylindrical article 10 is accommodated in a substantially central portion in the width direction of the cylindrical wall 4. it can. Furthermore, since the cylindrical article 10 is held in the hole 7 formed in the surface of the upper surface wall 5, the cylindrical article 10 is not easily displaced. Thus, the cylindrical article 10 accommodated by the interaction between the shape of the cylindrical wall 4 and the hole 7 is held at the center in the width direction of the cylindrical wall 4 without causing a positional shift in the width direction. .

The sheet | seat material which forms the packaging case 1 is not specifically limited, A conventionally well-known sheet | seat can be used.
Examples of the sheet material include a synthetic resin sheet, a synthetic resin sheet having a metal vapor-deposited layer, cardboard, and a laminated sheet thereof.
Preferably, a sheet including a synthetic resin sheet is used as the sheet material, and more preferably, a synthetic resin sheet (including a resin sheet in which two or more synthetic resin sheets are laminated) is used. Examples of the material of the synthetic resin sheet include polyolefins such as polypropylene and polyethylene, polyesters such as polyethylene terephthalate, polystyrenes, and polyamides. In particular, since it is excellent in bending resistance (hinge characteristics), a polypropylene sheet or a resin sheet in which polypropylene sheets are laminated is preferable.

  Moreover, it is preferable to use the sheet | seat excellent in transparency as a sheet | seat material. The sheet having excellent transparency is preferably a sheet having a total light transmittance of 70% or more, more preferably 80% or more, and further preferably 90% or more. However, the total light transmittance refers to a value measured by a measuring method in accordance with JIS K7105 (plastic optical property test method).

The sheet material is preferably colorless, but may be colored as long as the transparency is not impaired.
The thickness of the sheet material is not particularly limited, but is preferably about 0.2 mm to 1.0 mm.
When a polypropylene sheet is used, the sheet material preferably has a thickness of 0.2 mm to 0.6 mm because it has appropriate rigidity.

A cylindrical article 10 is accommodated in the cylindrical wall 4. The cylindrical article 10 is an article whose outer peripheral surface has a cylindrical body. The cylindrical article 10 includes not only the outer shape obtained by cutting the cylindrical article 10 in the horizontal direction (a plane orthogonal to the axial direction of the cylinder) in a perfect circle but also the one having a slightly elliptical outer shape. This is because an article having an elliptical outer shape can rotate when stored in the case.
Further, the cylindrical article 10 is a straight barrel type cylindrical article having substantially no diameter difference, or a cylindrical article having a diameter difference in any part in the vertical direction (for example, a multistage type, a rocket type, or a saddle type). Cylindrical article) and the like.
As the article 10 having such a cylindrical body, cosmetics placed in a substantially cylindrical container (the substantially cylindrical shape includes an elliptical shape as described above), a confectionery packaged in a substantially cylindrical container , Spray cans, cylindrical batteries and the like.

The cylindrical wall 4 is a cylindrical body having a front wall 2 that is a flat surface and a back wall 3 that is a circular arc surface. The upper part of the cylindrical wall 4 has an upper opening, and the lower part of the cylindrical wall 4 has a lower opening.
The front wall 2 is formed from a rectangular sheet piece having a predetermined width.
The width of the rectangular sheet piece forming the front wall 2 is not particularly limited, but is preferably formed to be about 1.5 to 3 times the diameter of the cylindrical article 10 to be stored, more preferably, It is formed about 1.8 times to 2.2 times.
For example, when the cylindrical article 10 having a diameter of about 30 mm is stored, the width of the front wall 2 is formed to be about 45 mm to 90 mm.
A header piece 74 is extended above the front wall 2. The header piece 74 is, for example, substantially the same width as the front wall 2 and is integrally extended from the upper side of the front wall 2. A suspension hole is formed in the center of the header piece 74 in the plane.

The back wall 3 is formed from a rectangular sheet piece that is wider than the width of the front wall 2.
Both sides of the back wall 3 are connected to both sides of the front wall 2 via a first crease line 1a and a second crease line 2a formed in a direction orthogonal to the width direction. The back wall 3 formed from a wide rectangular sheet piece having both sides connected to the front wall 2 is a circular arc surface bulging outward.
The width of the rectangular sheet piece forming the back wall 3 is preferably about 2 to 4 times the diameter of the cylindrical article 10 to be stored, and more preferably 2.2 to 3 times. Formed to a degree.

FIG. 6 is a development view of the sheet material 11 forming the packaging case 1.
Reference numeral 41 denotes a paste margin piece continuously provided on one side of the front wall 2. The tubular wall 4 is formed by bonding the adhesive margin piece 41 to the other side of the back wall 3.
Reference numerals 3a and 4a denote a third crease line and a fourth crease line formed in the vicinity of and parallel to the first crease line 1a and the second crease line 2a, respectively. When the cylindrical article 10 is not stored in the packaging case 1, the back wall 3 is flattened by bending the back wall 3 at the third and fourth crease lines 3a and 4a, so that the cylindrical wall 4 is flattened. Can be folded into a shape. However, the cylindrical article 10 can be stored at a predetermined position on the cylindrical wall 4 even if the third crease line 3a and the fourth crease line 4a are not formed.
In the case where the third crease line 3a and the fourth crease line 4a are formed, when the cylindrical article 10 is stored in the packaging case 1, the back wall 3 bends obtusely at the ruled lines 3a, 4a. The wall 3 becomes an arc surface having an obtuse angle portion at the crease lines 3a, 4a.
In addition, the code | symbol corresponding to each part of the packaging case 1 is attached | subjected to the sheet | seat material 11 of FIG.

In order to close the upper opening of the cylindrical wall 4, the upper surface wall 5 is fitted in the upper opening.
The top wall 5 is formed in a substantially trapezoidal shape in plan view.
In addition, in this specification, a planar view shape means the shape seen from the direction perpendicular | vertical with respect to a surface. Further, 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. Further, in the present specification, the upper base and the lower base include 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 trapezoidal 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 upper surface wall 5 is preferably disposed with its upper base facing the substantially central portion of the rear wall 3. By arranging the upper surface wall 5 in this way, the back wall 3 has an arcuate surface shape whose substantially central portion swells to the outermost side. Therefore, the cylindrical article 10 can be held at the substantially central portion in the width direction of the back wall 3.

Specifically, the upper bottom of the upper surface wall 5 is connected to the substantially central portion of the upper side of the back wall 3 via the fifth crease line 5a. By bending the upper surface wall 5 at the fifth crease line 5a formed along the upper base, the upper surface wall 5 is fitted into the upper opening of the cylindrical wall 4 and closes the upper opening.
A first connection piece 71 having a substantially triangular shape in plan view is connected between one oblique side of the top wall 5 and one side of the top side of the back wall 3 via a sixth crease line 6a and an eighth crease line 8a. It is installed. Similarly, between the other oblique side of the upper surface wall 5 and the other side of the upper side of the rear wall 3, a second connection piece 72 having a substantially triangular shape in plan view is connected via a seventh crease line 7a and a ninth crease line 9a. It is installed. The first connecting piece 71 and the second connecting piece 72 are formed by folding lines 6a and 7a formed along both oblique sides of the upper surface wall 5 and folded lines 8a formed along both sides of the upper side of the back wall 3. , 9a can be bent respectively.

The first connecting piece 71 and the second connecting piece 72 are generated between both the oblique sides of the upper surface wall 5 and the upper side of the back wall 3 when the upper surface wall 5 is fitted into the upper opening of the cylindrical wall 4. It is a piece that closes the gap and presses the inner surface of the back wall 3 outward.
Specifically, when the upper surface wall 5 is bent at the upper bottom, the first connection piece 71 and the second connection piece 72 are substantially the same as the outer surface of the upper surface wall 5 in the sixth crease line 6a and the seventh crease line 7a. Bends at right angles. When the first connecting piece 71 and the second connecting piece 72 are bent at a substantially right angle with respect to the outer surface of the upper surface wall 5, the inner surface of the back wall 3 is outside by the first connecting piece 71 and the second connecting piece 72. Has been pushed out. The back wall 3 is reinforced by the first connecting piece 71 and the second connecting piece 72, and the shape of the back wall 3 (in this embodiment, the arc surface of the back wall 3) is maintained.

On the other hand, a flap piece 73 is connected to the lower bottom of the top wall 5 via a tenth crease line 10a. The flap piece 73 can be bent via a tenth crease line 10a formed along the lower base.
The width of the flap piece 73 is preferably formed to be substantially the same as the width of the front wall 2.
The flap piece 73 is bent at about 90 degrees with respect to the inner surface of the upper surface wall 5 at the tenth crease line 10 a when the upper surface wall 5 is fitted into the upper opening of the cylindrical wall 4. The folded flap piece 73 is inserted along the inner surface of the front wall 2 inside the cylindrical wall 4.
Since the flap piece 73 is bent at the lower bottom of the upper surface wall 5 in this way, the straight shape of the lower bottom of the upper surface wall 5 is maintained (because the rigidity of the lower bottom of the upper surface wall 5 is increased), The flat surface shape of the front wall 2 is maintained.

Further, in the surface of the upper surface wall 5, a hole portion 7 having an edge close to the upper outer peripheral surface of the cylindrical article 10 to be accommodated, and a part of the edge of the hole portion 7 extends in the center direction of the hole portion 7. The urging piece portion 8 is formed.
For example, as shown in FIG. 6, the hole 7 and the urging piece 8 can be formed simultaneously by forming a cut line 9 made of an end line in the surface of the upper surface wall 5. In the case of the system in which the cut 9 is formed in the surface of the upper surface wall 5, an area extracted upward along the cut 9 (area surrounded by the cut formed by the end line) becomes the urging piece 8, and the area The opening portion that is generated after extracting the holes becomes the hole portion 7.

Specifically, the hole portion 7 is a portion opened in the surface of the upper surface wall 5 such that the upper portion of the cylindrical article 10 is seen from the hole portion 7 to the outside of the outer surface of the upper surface wall 5. It is. In order to easily understand the portion where the upper part of the cylindrical article 10 is peeped out from the hole portion 7, in FIG.
The edge of the hole portion 7 is formed so as to be close to the outer peripheral surface of the upper portion of the cylindrical article 10 that is seen through the hole portion 7. Note that “close” means that a part or all of the edge of the hole 7 is located in the vicinity of the upper outer peripheral surface of the cylindrical article 10, or a part or all of the edge of the hole 7 is of the cylindrical article 10. The case of contacting the upper outer peripheral surface is included.

When the upper part of the cylindrical article 10 is looked out (projects) from the hole part in the state of being close to the edge of the hole part 7, the cylindrical article 10 housed inside the cylindrical wall 4 is moved in the width direction. Misalignment can be prevented. Since it is possible to more reliably prevent the cylindrical article 10 from being displaced in the width direction of the cylindrical wall 4, the edge shape of the hole 7 is preferably substantially arcuate in plan view, and in particular, the cylindrical article 10. More preferably, it is formed in an arc shape that is substantially the same as the curvature of the upper outer peripheral surface.
Furthermore, since the cylindrical article 10 can be held at the center in the width direction of the cylindrical wall 4, the hole 7 is preferably formed at the center in the width direction of the upper surface wall 5.

Next, the urging piece 8 is a piece that urges the cylindrical article 10 peeking upward from the hole 7 toward the lower wall 6 side.
Further, since the urging piece 8 extends in the center direction of the hole portion 7, the urging piece portion 8 is positioned on the upper surface side of the cylindrical article 10 seen through the hole portion 7. Since the biasing piece portion 8 is positioned on the upper surface side of the cylindrical article 10 as described above, a portion where the cylindrical article 10 is exposed from the outer surface of the upper surface wall 5 (exposed portion of the cylindrical article 10) can be reduced. . In particular, it is preferable that the edge of the urging piece 8 is formed in an arc shape substantially the same as the edge of the upper surface of the cylindrical article 10 or an arc shape larger than the edge of the upper surface. By being formed in this way, the upper surface of the cylindrical article 10 peeking out from the hole 7 can be reliably covered with the urging piece 8, so that the exposed portion of the cylindrical article 10 can be made smaller. By reducing the exposed portion, it is possible to reliably prevent foreign matter from contacting the cylindrical article 10 and rotating the article 10 during distribution of the packaging case 1 in which the cylindrical article 10 is stored.

Further, since it has a larger urging force and is positioned substantially parallel to the upper surface of the stored cylindrical article 10, the surface of the urging piece 8 extends parallel to the surface of the upper surface wall 5. It is preferable that
The urging piece 8 may be in contact with the entire upper surface of the cylindrical article 10 to be stored, or may be in contact with a part of the upper surface of the cylindrical article 10 to be stored (the edge of the upper surface). May be. This is because the cylindrical article 10 to be stored can be urged downward by the urging piece 8 in any case.

The hole 7 and the biasing piece 8 can be formed, for example, by forming a slit 9 having a substantially semicircular arc shape in plan view. In the present embodiment, by cutting the upper surface wall 5 so as to bulge in an arc shape from the two starting points (both ends of the cut consisting of end lines) on the lower surface side of the upper surface wall 5 to the upper bottom side of the upper surface wall 5. The substantially semicircular arc-shaped cut 9 is formed. Thus, by forming both ends of the cut 9 on the lower bottom side of the upper surface wall 5 and forming the cut 9, when the upper surface wall 5 is fitted into the upper opening of the cylindrical wall 4, the cylindrical article 10 It is easy to introduce the upper part into the hole 7.
However, the substantially semicircular arc-shaped cut line 9 may be formed with its both ends positioned on the upper bottom side of the top wall 5 opposite to the formation position by 180 degrees. In this way, by forming both ends of the cut 9 on the upper bottom side of the upper surface wall 5 and forming the cut 9, the upper part of the cylindrical article 10 peeking out from the hole 7 is placed on the front wall 2 (header piece 74). ) Face to the side. For this reason, the exposed part of the cylindrical article 10 peeking out from the hole 7 hardly comes into contact with foreign matter.

Next, in order to close the lower opening of the cylindrical wall 4, the lower surface wall 6 is fitted in the lower opening.
A cylindrical article 10 is placed on the inner surface of the lower wall 6. In order to prevent the lower surface wall 6 from bulging downward by the cylindrical article 10 urged downward by the urging piece portion 8, the lower surface wall 6 is formed at a central portion in a direction orthogonal to the width direction. It is bent in a mountain shape. Since the lower surface wall 6 having a mountain shape in cross section is not easily deformed by a load, the cylindrical article 10 can be sandwiched between the lower surface wall 6 and the biasing piece portion 8 without being displaced in the vertical direction.
The bottom wall 6 fitted into the lower opening of the cylindrical wall 4 has a mountain shape in cross-sectional view as described above, but the shape when viewed from below is substantially trapezoidal (FIG. 4). reference). In the present embodiment, the shape of the lower surface wall 6 (the shape when viewed from below) is formed in substantially the same shape as the planar view shape of 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 with its lower base facing the front wall 2 side. Similarly to the upper surface wall 5, the lower surface wall 6 is preferably arranged with its upper base facing the substantially central portion of the back wall 3. By arranging the lower surface wall 6 in this way, the back wall 3 has an arcuate surface shape whose substantially central portion swells to the outermost side. Therefore, the cylindrical article 10 can be held at the substantially central portion in the width direction of the back wall 3.

Specifically, the lower surface wall 6 is connected to the first piece 75 connected to the lower side of the front wall 2 via a twelfth crease line 12a and to the first piece 75 via an eleventh crease line 11a. The second piece 76 and the third piece 77 having a substantially trapezoidal shape in a plan view connected to the substantially central portion of the lower side of the back wall 5 through the thirteenth crease line 13a.
By bonding the third piece 77 to the second piece 76 and bending the first piece 75 and the third piece 77 in a mountain shape at the eleventh crease line 11a, the lower wall 6 is formed in the lower opening of the cylindrical wall 4. Is formed.

Next, the procedure for assembling the packaging case 1 and storing the cylindrical article 10 in the packaging case 1 will be described.
The adhesive margin piece 41 is bonded to the other side of the back wall 3 while the sheet material 11 cut into a shape as shown in FIG. 6 is bent at the first to fourth crease lines 1a, 2a, 3a, 4a. At the same time, the first piece 75 and the third piece 77 are folded inward at the twelfth crease line 12a and the thirteenth crease line 13a, respectively, and the second piece 76 is folded on the outer surface of the second piece 76 at the eleventh crease line 11a. The third piece 77 is bonded. In this way, the cylindrical wall 4 whose lower opening is closed by the lower wall 6 and whose upper opening is open can be obtained.

The cylindrical article 10 is inserted into the cylindrical wall 4 from the upper opening thereof in alignment with the substantially central portion in the width direction of the cylindrical wall 4.
Next, the top wall 5, the first connecting piece 71, and the second connecting piece 72 are simultaneously bent inward at the fifth to ninth crease lines 5 a, 6 a, 7 a, 8 a, 9 a. At this time, the upper surface wall 5 is bent so that the upper surface of the cylindrical article 10 coincides with the hole 7 (region surrounded by the cut 9) formed in the upper surface wall 5.
When the upper surface wall 5 is bent in this manner, as shown in FIG. 1, the urging piece 8 is slightly pushed upward by the upper surface of the cylindrical article 10 (the cylindrical article 10 is pushed downward by the urging piece 8. When the upper part of the cylindrical article 10 is looked out of the hole part 7 slightly, the edge of the hole part 7 comes close to the upper outer peripheral surface of the cylindrical article 10. Further, the first connecting piece 71 and the second connecting piece 72 are bent at a substantially right angle with respect to the outer surface of the back wall 3 at the sixth fold line 6a and the seventh fold line 7a, thereby reinforcing the back wall 3.
Then, by folding the flap piece 73 at the tenth crease line 10a and inserting it into the cylindrical wall 4, a packaging case 1 (article packaging body) containing the cylindrical article 10 as shown in FIG. 1 is obtained. can get.

The article packaging body (the packaging case 1 in which the cylindrical article 10 is accommodated) can be suspended and displayed by, for example, passing a suspension hole of the header piece 74 of the packaging case 1 through a hanger rod. When suspending, it is preferable to display so that the front wall 2 of the packaging case 1 can be seen by the consumer.
Moreover, the said article packaging body can also stand on the display shelf with the lower surface wall 6 of the packaging case 1 downward, and can display (self-standing display). In the packaging case 1, the front wall 2 constituting the cylindrical wall 4 is a flat surface, and therefore, a plurality of article packaging bodies can be independently displayed with the front wall 2 facing the front side. In this way, the product packaging body is self-standing by facing the front wall 2 to the front side, thereby giving an orderly image to the consumer, and from the front wall 2 side of the packaging case 1 to the consumer, the cylindrical article. 10 can be shown well.

Moreover, since the back wall 3 which comprises the cylindrical wall 4 is the circular arc surface, the cylindrical article 10 accommodated in the inside of the cylindrical wall 4 is the front wall 2 and the circular wall rear wall 3 in the packaging case 1. It is hold | maintained between the approximate center part. Furthermore, since the edge of the hole is close to the upper outer peripheral surface of the cylindrical article 10, the stored cylindrical article 10 can be prevented from being displaced in the width direction of the cylindrical wall 4.
Further, since the stored cylindrical article 10 is sandwiched between the urging piece 8 and the lower wall 6, the cylindrical article 10 is not easily displaced in the vertical direction and is difficult to rotate.
For this reason, the packaging case 1 can hold the cylindrical article 10 at a predetermined position of the cylindrical wall 4 (substantially central portion of the back wall 3) without using a separate holding member. It is possible to prevent the cylindrical article 10 from being misaligned during the distribution.
Furthermore, since the upper surface wall 5 and the lower surface wall 6 are formed in a substantially trapezoidal shape, the packaging case 1 can maintain the arc surface shape of the back wall 3.

Next, other embodiment of the packaging case 1 of this invention is shown.
Hereinafter, other embodiments will be described, but the description of the same configurations and effects as those of the above embodiments may be omitted, and terms and drawing numbers may be used (for example, in the drawings, the same as the above embodiments). The reference numeral is given to the member or part, and the description of the member or part is omitted in the specification).
In the above embodiment, the cut line 9 has an arcuate line shape, but may have an angular line shape or the like.
The cut is not limited to a linear shape, and may be a cut formed by punching the surface of the upper surface wall 5 into a predetermined shape (for example, a crescent-shaped punch).
As shown in FIG. 7, for example, the upper surface wall 5 having a notch 9 punched out in a crescent shape has a hole 7 through which the upper part of the cylindrical article 10 looks out, and the cylindrical article 10 downward. And an urging piece 8 for urging the lens.

In the above embodiment, the lower wall 6 is formed in an upward mountain shape, but the lower wall 6 may be formed so as not to swell downward when the cylindrical article 10 is pushed down.
For example, as shown in FIGS. 8 and 9, the lower surface wall 6 may be composed of a fourth piece 78 that is inclined upward and a fifth piece 79 provided below the fourth piece 78. Good. The fifth piece 79 is folded at the center thereof, and has an action of urging the fourth piece 78 upward. Similarly to the above embodiment, the lower surface wall 6 having the upwardly inclined fourth piece 78 biased upward is not easily deformed by a load. Therefore, a cylindrical shape is formed between the lower surface wall 6 and the biasing piece portion 8. The article 10 can be held without being displaced in the vertical direction.

  In the above embodiment, the lower surface wall 6 is formed by bonding the first piece 75 (and the second piece 76) connected to the front wall 2 and the third piece 77 connected to the back wall 3. However, similarly to the upper surface wall 5, the lower surface wall 6 is connected to the lower side of the front wall 2 or the lower side of the rear wall 3, and the lower surface wall 6 is fitted into the lower opening of the cylindrical wall 4. But you can.

In the said embodiment, although the front wall 2 is made into the flat surface, the front wall 2 is not restricted flat. In the packaging case 1 of the present invention, the back wall 3 has an arcuate surface (or polygonal surface), so that the cylindrical article 10 is placed in a predetermined position of the cylindrical wall 4 according to this shape (for example, the width of the cylindrical wall 4). It can be stored and held in the direction center.
For example, FIGS. 10 to 13 show a packaging case 1 in which the front wall 2 is formed in a non-flat shape.
The lower part of the front wall 2 of the packaging case 1 is an arc surface or a trapezoidal side surface, and is gradually flattened from the lower part toward the upper part.
In addition, the expanded view of the sheet | seat material which forms this packaging case 1 is shown in FIG.

The packaging case 1 shown in FIGS. 10-13 has the lower surface wall 6 bent in the shape of a mountain like the packaging case 1 shown in FIG. 1, but when the lower surface wall 6 is viewed from below, the shape is as follows. It is a horizontally long hexagonal shape.
As shown in FIG. 14, the lower wall 6 has a substantially trapezoidal first piece 75 provided continuously with the lower side of the front wall 2 and a substantially trapezoidal third piece provided continuously with the lower side of the back wall 5. 77. The second piece 76 connected to the first piece 75 is bonded to the third piece 77, and the first piece 75 and the third piece 77 are bent into a mountain shape at the eleventh crease line 11a, thereby laterally. The bottom wall 6 having a mountain shape when viewed from the side and a horizontally long hexagonal shape when viewed from below can be formed.
The edge of the free end of the bottom hexagonal bottom wall 6 is in strong contact with the inside of the front wall 2 and the back wall 3. For this reason, the strength of the lower surface wall 6 is increased, and even when the packaging case 1 is transported in a state where the cylindrical article 10 is stored in the cylindrical wall 4, the lower surface wall 6 does not come off.

  In the said embodiment, although the flap piece 73 formed in the upper surface wall 5 is inserted in the inside of the cylindrical wall 4 and along the inner surface of the front wall 2, as shown in FIG.8 and FIG.9, for example. In addition, the flap piece 73 may be attached along the header piece 74 that protrudes from the front wall 2 outside the cylindrical wall 4.

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.

  The packaging case of the present invention stores, for example, articles having a substantially cylindrical outer peripheral shape (for example, cosmetics put in a substantially cylindrical container, confectionery packed in a substantially cylindrical container, spray cans, etc.). Can be used for
