However, in the above-mentioned packaging box, when the top lid is closed, there is a risk that the insertion flap may interfere with the upper end of the product, which makes it difficult to insert the insertion flap. In particular, when closing the top cover while mechanically bending the top cover flap and the insertion flap, there is a problem in that it is difficult to adjust the machine.

To solve this problem, it is possible to provide a clearance between the top lid of the packaging box and the product so that the insertion flap does not interfere with the product, but this increases the height of the packaging box and A problem arises in that the box becomes larger. To deal with this, it is possible to shorten the insertion flap and reduce the clearance, but if you do that, the contact area between the insertion flap and the box body will become smaller, and there is a risk that the top cover will open. . The present invention was made in order to solve the above problem, and an object of the present invention is to provide a package into which an insertion flap can be easily inserted.

A package according to the present invention includes a packaging box and at least one article accommodated in the packaging box, the packaging box having an upper opening and a lower opening, and capable of accommodating the article. The box body includes a main body, an upper lid part that opens and closes the upper opening, and a lower lid part that covers the lower opening, and the box main body has opposing first and second surfaces, an opposing third surface, and a lower lid that covers the lower opening. The upper opening of the box body is formed in a rectangular tube shape with a fourth surface, and the upper opening of the box body is connected to the upper end of the first surface, the second surface, the third surface, and the fourth surface. The upper lid part is formed into a rectangular shape by a first side, a second side, a third side, and a fourth side, and the upper lid part includes an upper lid flap that is bendably connected to the first side and closes the upper opening, and the upper lid flap. an insertion flap that is bendably connected to the tip of the flap and inserted into the upper opening so as to contact the second surface; and a pair of horizontal flaps that are bendably connected to each of the third and fourth sides. and a clearance of a first length in the height direction between the upper end of the article and the upper lid when the article is placed in the lower lid and housed in the packaging box. The insertion flap has at least one recessed portion, and a length of insertion into the upper opening where the recessed portion is formed is shorter than the first length.

According to this configuration, when an article is stored in the packaging box, a clearance of the first length is formed between the upper end of the article and the top lid, and the insertion flap inserted into the upper opening of the packaging box has a clearance of the first length. A recess is formed, and the insertion length of the part where the recess is formed into the upper opening is shorter than the first length. Therefore, when the insertion flap is inserted into the upper opening, the portion where the recess is formed does not come into contact with the article. Therefore, since interference between the insertion flap and the article can be reduced when inserting the insertion flap, the insertion flap can be easily inserted.

Moreover, since there is no need to make the height of the packaging box unnecessarily high in order to prevent interference between the insertion flap and the article, the packaging box can be made as small as possible.

The parts of the insertion flap other than where the recess is formed have a long insertion length into the upper opening, ensuring a contact area with the second surface, so it is difficult for the insertion flap to separate from the upper opening. can be suppressed.

When the insertion flap is inserted into the upper opening, the tip of the insertion flap is inserted while contacting the second surface, but at this time, the tip of the insertion flap and the second The length of contact with the surface can be shortened. That is, since the portion in which the recess is formed does not come into contact with the second surface, friction between the insertion flap and the second surface can be reduced. As a result, the insertion flap can be easily inserted.

In the package, one recess may be formed near the center of the insertion flap, and both sides of the recess on the insertion flap may form protrusions.

According to this configuration, since the recess is formed near the center of the insertion flap, interference between the article and the insertion flap near the center of the second side of the packaging box can be reduced. That is, since interference between the insertion flap and the article can be suppressed at a location where the article is most likely to be placed, the insertion flap can be more easily inserted.

In the package, the length of the recess in the direction of the first side is not particularly limited, but may be, for example, 50% or more of the length of the first side. Thereby, interference between the insertion flap and the article can be further reduced.

In the above-mentioned package, both edges of the recessed portion may be formed in a curved shape that is convex toward the upper lid flap.

Although the insertion flap does not interfere with the article at the location where the recess is formed, it may interfere with the article on both sides thereof. Therefore, by forming both edges of the recess into a curved shape that is convex toward the top lid flap side, both edges of the recess can be brought into smooth contact with the article while the insertion flap is being inserted. Therefore, even if the article and the insertion flap interfere, the insertion flap can be easily inserted.

In the package, when the article is placed in a position in contact with either the third surface or the fourth surface and the second surface, the article contacts the second surface. The article may be formed such that a gap is formed between the contact position and the one surface.

According to this configuration, since the article is formed such that a gap is formed between the contact position where the article contacts the second surface and one surface, the protrusion is inserted into this gap. be able to. As a result, the article and the protrusion do not interfere with each other, or the interference can be reduced, making it easier to insert the insertion flap.

In the package, the planar shape of the upper end of the article can be circular or elliptical.

According to this configuration, since the planar shape of the upper end of the article is circular or elliptical, the shape of the edge of the article corresponding to the above-mentioned gap can be curved. Thereby, even if the protruding part touches the edge of the article, it can be inserted along the curve, so the insertion flap can be easily inserted.

In the package described above, the length of the protruding portion along the first side can be formed to be shorter than the length between the contact position and the one surface.

According to this configuration, the protrusion can be inserted into the gap without coming into contact with it. Therefore, the insertion flap can be inserted more easily.

According to the packaging box of the present invention, the insertion flap can be easily inserted into the upper opening of the box body.

Hereinafter, one embodiment of the package according to the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of the package. As shown in FIG. 1, this package includes two cylindrical products (articles) 1 and 2, and a packaging box 3 that accommodates these articles. Each member will be explained in detail below. Note that although the following description will be made based on the direction shown in FIG. 1, the package according to the present invention can be configured without being limited to this direction.

<1. Overview of packaging box>
FIG. 2 is a developed view of the packaging box. As shown in FIG. 1, the packaging box according to this embodiment is a vertically elongated rectangular parallelepiped, and includes a rectangular tube-shaped box body 4 in which products 1 and 2 are housed. A lower lid part 5 is formed by a so-called one-touch bottom at the lower opening of the box body 4, and an upper lid part 6 and a header part 7 are provided at the upper opening. First, a developed view of this packaging box will be described with reference to FIG. 2. In the following description, for convenience of explanation, the horizontal direction in FIG. 2 is sometimes referred to as the width direction, and the vertical direction is sometimes referred to as the vertical direction.

The packaging box according to this embodiment can be unfolded as shown in FIG. 2, and is made of a deformable thin plate-like material such as plastic or paper. The box body 4 of this packaging box has a rectangular first side part 41, a front part 42, a second side part 43, and a back part 44 connected in this order from right to left in FIG. ing. The connecting portions of these parts are bendable. Further, an adhesive margin portion 45 is bendably connected to the left side of the back surface portion 44, and the adhesive margin portion 45 is adhered to the rear surface of the first side surface portion 41 when the box main body 4 is assembled. In addition, in FIG. 2, the bending line is represented by a thin line.

The front section 42 is the surface facing the front of the packaging box, and displays, for example, the name of the product. On the other hand, the back part 44 is formed to have the same size as the front part 42, and is arranged at a position facing the front part 42 when the packaging box is assembled. Further, on the back portion 44, for example, how to use the product, ingredient list, company name, etc. are displayed. The first side surface portion 41 and the second side surface portion 43 are formed to have the same size, the first side surface portion 41 is disposed on the right side toward the front surface portion 42, and the second side surface portion 43 faces the first side surface portion 41. That is, on the left side when facing the front section 42. The upper opening 401 and lower opening 402 of the box body 4 are formed in a rectangular shape. In addition, the front part 42 can also be used as the back surface of the packaging box 3, and the back surface part 44 can be used as the front surface of the packaging box 3, and a display can be made accordingly.

Next, the header section 7 will be explained. As shown in FIG. 1, the header portion 7 protrudes upward from the upper end of the box body 4, and has a hanging hole 70 formed therein. A hanging rod of a display shelf is inserted into the hanging hole 70 to hang the package. The header section 7 includes a first header plate 71 and a second header plate 72 that are formed into plate shapes. The first header plate 71 projects upward from the upper edge of the back section 44 and is formed in a rectangular shape with the same width as the back section 44 . Further, the second header plate 72 is bendably connected to the upper edge of the first header plate 71, and is formed in a rectangular shape with the same width as the first header plate 71. However, the length of the second header plate 72 in the vertical direction is longer than that of the first header plate 71. Therefore, when the packaging box 3 is assembled, when the second header plate 72 is bent so as to overlap the first header plate 71, it is inserted into the inside of the box body 4 through the upper opening 401. There is. Further, through holes 711 and 721 are formed in the first header plate 71 and the second header plate 72, respectively, and when both the header plates 71 and 72 are overlapped, both the through holes 711 and 721 are aligned. Accordingly, the above-mentioned hanging hole 70 is formed.

Next, the upper lid part 6 will be explained with reference to FIG. 3 as well. FIG. 3 is a perspective view showing the top lid in an open state. The upper lid part 6 includes a rectangular upper lid flap 61 bendably connected to the upper edge (first side) of the front part 42, an insertion flap 62 bendably connected to the tip of this upper lid flap 61, and a first It is comprised of a first upper horizontal flap 63 and a second upper horizontal flap 64, which are bendably connected to the upper sides of the side surface portion 41 and the second side surface portion 43, respectively.

The top lid flap 61 is formed into a rectangular shape that is approximately the same size as the top opening 401 of the box body 4. As will be described later, in order to prevent the insertion flap 62 from coming off, it is preferable that the length in the front-rear direction (the length between the front part 42 and the back part 44) is slightly shorter than that of the upper opening 401. . Moreover, when the upper lid part 6 closes the upper opening 401 of the box main body 4, the insertion flap 62 is inserted into the upper opening 401 so as to overlap with the second header plate 72 described above.

As shown in FIG. 2, the insertion flap 62 is formed in a band shape extending in the width direction, and both sides of the upper end are formed in an arc shape. Further, a recess 65 extending in the width direction is formed at the center of the upper end. The recess 65 includes a bottom edge 651 that extends linearly in the width direction, and a pair of side edges 652 that extend upward from both ends of the bottom edge 651. The side edge portions 652 extend downward from both sides of the bottom edge portion 651 in a convex arc shape (formed in a curved concave shape), and are connected to the tip edge of the insertion flap 62 . Further, the connection portion between the side edge portion 652 and the tip edge of the insertion flap 62 is also formed in an arc shape. By forming such a recess 65, protrusions 653 are formed at both ends of the insertion flap 62 on both sides of the recess 65. Here, the width D1 of the recessed portion 65 indicates the distance between the upper ends of the side edge portions 652, and this width D1 is 50% to 50% of the width D2 of the base end portion of the insertion flap 62 (connection portion with the upper lid flap). It is preferably over 90%, more preferably 70% to 80%. This is because when the width D1 is 50% or more, the effect of reducing interference between the insertion flap 62 and the products 1 and 2 becomes greater, as will be described later, and when it is 90% or less, the insertion flap 62 This is because it can be prevented from easily separating from the upper opening 401.

Further, in the insertion flap 62, the insertion length of the portion where the recess 65 is formed is defined as H1. The insertion length H1 is the distance between the base end of the insertion flap 62 and the bottom edge 651 of the recess 65. Further, the distances between both ends 6511 and 6512 of the bottom edge portion 651 and both sides of the insertion flap are defined as K1 and K2. The distances K1 and K2 can also be defined as the width of the protrusion 653.

The first upper lateral flap 63 is bendably connected to the upper edge of the first side part 41, and the second upper lateral flap 64 is bendably connected to the upper edge of the second side part 43. These both lateral flaps 63, 64 are formed into rectangular shapes of the same size. The width of the first upper horizontal flap 63 is approximately the same as the upper side of the first side surface portion 41, and the length of the first upper side flap 63 protruding from the first side surface portion 41 is slightly shorter than half the width of the front portion 42. The same applies to the second upper horizontal flap 64.

Next, the lower lid part 5 will be explained. The lower lid portion 5 is formed with a so-called one-touch bottom. Specifically, as shown in FIG. 2, a first large flap 51 bendably connected to the lower edge of the front part 42, a second large flap 52 bendably connected to the lower edge of the back part 44, It is comprised of a first small flap 53 bendably connected to the lower edge of the first side part 41 and a second small flap 54 bendably connected to the lower edge of the second side part 43. Both large flaps 51, 52 are provided with rectangular flap bodies 511, 521, and one side (hereinafter referred to as the "bending side") 512, 522 of the flap bodies 511, 521 is provided with a triangular glue so that it can be folded. The margins 513 and 523 are connected. Each adhesive margin 513, 523 is adapted to be adhered to an adjacent small flap 53, 54. Further, recesses 514 and 524 are formed near the center of each flap body 511 and 521, and when these recesses 514 and 524 engage with each other, both flap bodies 511 and 521 are fixed to each other. It has become. On the other hand, both small flaps 53 and 54 are formed in a trapezoidal shape.

<2. Products>
Next, products 1 and 2 will be explained with reference to FIGS. 4 to 6. FIG. 4 is a longitudinal cross-sectional view of the packaging box in which the product is stored, FIG. 5 is a view of the inner wall surface of the back plate viewed from the front, and FIG. 6 is a cross-sectional view of FIG. 1. The products 1 and 2 according to this embodiment are formed into a cylindrical shape, as shown in FIG. Here, for convenience of explanation, the product placed on the left side will be referred to as a first product 1, and the product placed on the right side will be referred to as a second product 2. First, as shown in FIG. 4, when both products 1 and 2 are housed in the packaging box 3, the bottom surfaces of both products 1 and 2 are placed on the lower lid part. At this time, a gap having a length H2 (first length) in the vertical direction is formed between the upper ends of both products 1 and 2 and the upper lid part 6. This length H2 is longer than the insertion length H1 of the insertion flap 62 where the recess 65 is formed. Since the heights of the products 1 and 2 and the packaging box 3 are defined in this way, the recess 65 does not interfere with the upper ends of the products 1 and 2, as shown in FIGS. 4 and 5. There is. Further, as shown in FIG. 4, the lower end of the bent second header plate 72 extends to approximately the same position as the bottom edge 651 of the recess 65, so that the second header plate 72 also extends to the product 1, It is designed not to interfere with the upper end of 2.

As shown in FIG. 6, the total length of the outer diameters of the two products 1 and 2 is smaller than the width of the packaging box 3. Therefore, the products 1 and 2 are movable in the width direction within the packaging box 3. However, since the length of the packaging box 3 in the front-rear direction (distance between the front part 42 and the back part 44) is approximately the same as the outer diameter of the products 1 and 2, 2 is restricted from moving back and forth.

Further, since the first product 1 is formed to have a circular cross section, when it comes into contact with the back surface portion 44 and the second side surface portion 43, there is a gap in the width direction between the contact point E with the back surface portion 44 and the second side surface portion 43. A triangular gap C1 in a plan view having a length S1 is formed. Similarly, since the second product 2 is also formed to have a circular cross section, when it comes into contact with the back surface portion 44 and the first side surface portion 41, there is a gap between the contact point F with the back surface portion 44 and the first side surface portion 41 in the width direction. A triangular gap C21 having a length S2 in plan view is formed. The widths S1 and S2 of these gaps C1 and C2 are wider than the widths K1 and K2 of the protrusions of the insertion flap mentioned above. Therefore, when the insertion flap 62 is inserted into the upper opening 401, the protrusion 653 is inserted without interfering with the side surfaces of the products 1 and 2.

<3. Assembling the packaging box>
Next, assembly of the packaging box configured as described above will be explained with reference to FIGS. 7 and 8. FIG. 7 is a sectional view of the packaging box containing the product, and FIG. 8 is a perspective view showing the state in which the top lid is closed. In addition, in FIG. 8, the first upper horizontal flap 63 and the second upper horizontal flap 64 are omitted. First, the box body 4 is assembled from the unfolded state as shown in FIG. Specifically, the connecting portions of each portion 41 to 45 are bent and the margin portion 45 is adhered to the inner wall surface of the first side portion 41 to form a rectangular tube shape. At this time, the second header plate 72 is also bent and inserted into the box body 4 through the upper opening 401.

Next, the lower lid part 5 that closes the lower opening 402 of the box body 4 is assembled. First, while bending the bent side 512 of the first large flap 51, a glue margin 513 is glued to the adjacent first small flap 53. At this time, the bent side 512 of the first large flap 51 and the oblique side of the first small flap 31 are made to match. Similarly, while bending the bent side 522 of the second large flap 52, a glue margin 523 is glued to the second small flap 54 adjacent thereto. At this time, the bent side 522 of the second large flap 52 and the oblique side of the second small flap 54 are made to match. In this state, when all the flaps are moved so that they are located on the same plane, the recess 514 of the first large flap 51 and the recess 524 of the second large flap 52 engage, and a rectangular shape that closes the lower opening 102 is formed. A lower lid portion 5 is formed.

Following this, the first and second products 1 and 2 are accommodated into the internal space of the box body 4 through the upper opening 101 of the box body 4. Next, the upper lid part 6 that closes the upper opening 401 of the box body 4 is assembled. First, after bending both upper side flaps 63 and 64, the top lid flap 61 and insertion flap 62 are bent. Then, as shown in FIGS. 7 and 8, the top cover flap 61 is bent while the tip of the insertion flap 62 is aligned with the header part 7, and the insertion flap 62 is inserted into the upper opening 401. At this time, the insertion flap 62 is inserted with only the protruding portion 653 in contact with the header portion 7 . In this way, the upper opening 401 is closed by the upper lid flap 61, and the assembly of the packaging box 3 is completed.

<4. Features>
According to this embodiment, the following effects can be obtained.
(1) When the products 1 and 2 are stored in the packaging box, a clearance of length H2 is formed between the upper ends of the products 1 and 2 and the upper lid part 6, and the upper opening 401 of the packaging box 3 is A recess 65 is formed in the insertion flap 62 to be inserted, and the length H1 of the insertion into the upper opening 401 where the recess 65 is formed is shorter than H2. Therefore, when the insertion flap 62 is inserted into the upper opening 401, the portion where the recess 65 is formed does not come into contact with the products 1 and 2. Therefore, when inserting the insertion flap 62, interference between the insertion flap 62 and the products 1 and 2 can be reduced, so that the insertion flap 62 can be easily inserted.

(2) Since there is no need to unnecessarily increase the height of the packaging box 3 in order to prevent interference between the insertion flap 62 and the products 1 and 2, the packaging box 3 can be made as small as possible.

(3) In the insertion flap 62, a portion other than the concave portion 65, that is, the protruding portion 653 has a long insertion length into the upper opening 401, and has a contact area with the header portion 7 and the back portion 44. Since this is ensured, it is possible to suppress the insertion flap 62 from coming off from the upper opening 401. Note that the insertion length of the protrusion 653 is preferably about 15 to 20 mm, for example.

(4) When the insertion flap 62 is inserted into the upper opening 401, the tip of the insertion flap 62 is inserted while contacting the header part 7. The length of contact between the tip of the flap 62 and the header portion 7 can be shortened. That is, as shown in FIG. 8, the part of the insertion flap 62 where the recess 65 is formed does not contact the header part 7, and only the protruding part 653 contacts the header part 7. Friction with the header portion 7 can be reduced. As a result, the insertion flap 62 can be easily inserted.

(5) In this embodiment, as shown in FIG. is also large, so that the protruding portion 653 does not come into contact with the products 1 and 2 when the insertion flap 62 is inserted. Therefore, the insertion flap 62 can be easily inserted. Note that since the upper ends of the products 1 and 2 are circular, the edges of the products 1 and 2 forming the gaps C1 and C2 are formed in an arc shape, as shown in FIG. Therefore, even if the protruding part 653 interferes with the products 1 and 2, the protruding part 653 is inserted along the arcuate edge, so it can be inserted smoothly. In particular, since the side edge of the protrusion 653, that is, the side edge 652 of the recess 65, is formed in an arcuate shape convex toward the upper lid flap 61 side (formed in a curved concave shape), This allows for smoother insertion.

<5. Modified example>
Although one embodiment of the present invention has been described above, the present invention is not limited to this, and various changes can be made without departing from the spirit thereof. Note that the following modifications can be combined as appropriate.

(1) The shapes of the products 1 and 2 are not particularly limited, and in addition to the cylindrical shape as in the above embodiment, as shown in FIG. ), rhombus (c), ellipse (d), and various other shapes. However, as shown in FIGS. 9(b) to 8(d), if the shape forms a gap between the side parts 41, 43 and the products 1, 2, the protruding part 653 is likely to be inserted. Preferably, as shown in FIG. 9(d), it is even more preferable that the outer edges of the products 1 and 2 are curved, since interference with the protrusion 653 can be alleviated.

Further, the number of products housed in the packaging box 3 is not particularly limited, and may be one, or three or more. Furthermore, the shapes of the plurality of products may not be the same. Further, as shown in FIG. 6, the products 1 and 2 may be arranged so as to be movable in the width direction, or the size of the packaging box 3 in the width direction may be adjusted so that they cannot be moved in the width direction. You can also do it. In this way, the size of the packaging box 3 in the width direction and the front-back direction can be adjusted as appropriate.

(2) The shape of the recessed portion 65 of the insertion flap 62 is not particularly limited, and may be formed in any direction in the width direction of the insertion flap 62 so as to reduce interference with the products 1 and 2. However, it is preferable to form it near the center of the insertion flap 62 in the width direction. Further, the number of recesses 65 is not particularly limited, and a plurality of recesses 65 may be formed.

(3) The form of the lower lid part 5 is not particularly limited, as long as it can close the lower opening 402. Therefore, for example, it can be configured similarly to the upper lid part 6.

(4) The header portion 7 is not necessarily required, and may be provided as appropriate.
