Description

This disclosure relates to a storage container for storing items such as merchandise.

Packaging containers suitable for displaying and selling cosmetics and other products are being used. Traditionally, product packaging containers were made of a backing with a transparent film or container attached to the product, but in recent years, due to concerns about marine pollution caused by microplastics, packaging that does not use plastic or other resins has become popular. For this reason, the style of storing products in paper packaging containers is becoming more common.

A type of paper product storage container that can be assembled into a box shape is used, but there is a problem in that it is time-consuming and requires a sealing operation of assembling the box, storing the product, and sealing it. Therefore, a product storage container has been proposed in which the product storage container is prepared in advance, and when the container is sealed, the container is raised from a folded state into a three-dimensional state and the product is inserted (for example, Patent Document 1). . An example of such a product storage container is shown in the developed view of FIG. 24 and the perspective view of FIG. 27. This product storage container 900 can store the product GD as shown in FIG. 29 by press-fitting the product GD through an insertion hole 903 formed at the bottom of the product storage container 900 as shown in FIG. Further, as shown in FIG. 30, this product storage container 900 is provided with a break section 945 for taking out on the back side, and as shown in FIG. 31, the product GD can be taken out from above by breaking the break section 945. There is.

This product storage container 900 has flaps 950 and 960 provided at the lower ends of two body plates 910 and 930, respectively, as shown in the developed view of FIG. 24, and two flaps 950 and 960 as shown in FIG. are joined to form the bottom. When the assembled product storage container 900 is in the folded state as shown in FIG. 26, the two flaps 950 and 960 at the lower end are each folded into a mountain shape and then folded back. In this product storage container, a pillow-shaped storage space is formed by expanding the center between two body plates 910 and 930, and a cylindrical product GD as shown in FIG. 28 is placed in this storage space. Store it. As shown in the sectional view of FIG. 29, the stored product GD is said to be prevented from falling out by supporting its lower surface with flaps 950 and 960. Specifically, a repulsive force acts on the flaps 950 and 960 folded back at the lower ends of the body plates 910 and 930 to return to their original positions, and as a result, the insertion hole 903 attempts to transform from the vertical position to the horizontal position in FIG. It is said that the product GD is deformed in a direction that blocks it and supports the lower surface of the product GD.

However, the inventor's tests have revealed that this type of product storage container has a problem in that the product GD is easily removed after it is inserted. As described above, this product storage container stores the product GD in a pillow-shaped storage space between two trunk panels 910 and 930 by expanding the center. When a product is stored in such a storage space, a fold FD1 is formed along the longitudinal direction of the trunk panels 910 and 930 as shown in FIG. 32. This fold FD1 is formed in a direction perpendicular to the fold line FD2 formed by folding the two flaps 950 and 960 in a mountain shape. When the fold FD1 is formed in this way, intersecting with the original fold line FD2, the repulsive force of the fold line FD2 to return to its original state is greatly reduced. As a result, it has been found that the flaps 950 and 960 do not close neatly after the product is pressed in as shown in FIG. 29, but remain open, causing a problem in which the product GD is easily removed. In particular, in a configuration in which the product GD is inserted from the bottom of the product storage container 900 as shown in FIG. 28, the insertion hole 903 is formed on the bottom side, so there is a risk that the product GD may fall out naturally due to its own weight.

FIG. 16 shows a perspective view taken along the line XVI-XVI in FIG. 15, respectively.

The product storage container 100 is a container that stores items GD such as goods inside, as shown in FIG. 2. The material is non-plastic and can be paper such as white cardboard, yellow cardboard, and chipboard. As shown in the development diagram of FIG. 1, the paper product storage container 100 is printed, punched, etc., to create the state shown in the development diagram, and then each part is folded and glued to assemble. The assembled product storage container 100 can be folded as shown in FIG. 10 to reduce the volume and make it easier to store and transport. On the other hand, when storing items GD such as goods, the bottom 1 is expanded as shown in FIG. 11 and FIG. 12, and the goods are stored as shown in FIG. 7. This product storage container 100 does not require the box-making process that was previously required, such as opening the lid before storing goods and closing the lid after storage. The stored items GD are removed from the side by breaking the second body panel 20 (details will be described later).

Examples of the stored items GD include bottles and tubes of cosmetics, medicines such as eye drops, foods, miscellaneous goods, and the like. When the product is stored in the product storage container 100, it can be made free-standing or can be hung from a hook or the like so that it can be easily displayed or sold. The examples shown in FIGS. 2 to 4 and 6 to 9 show a free-standing product storage container 100 that stores a cylindrical bottle.
(First body plate 10)

The product storage container 100 includes a first body plate 10, a second body plate 20, and a third body plate 30, as shown in the developed view of FIG. The first body plate 10 has a vertically long rectangular shape, and in the figure, the long side on the left side is the first side 11, the long side on the right side is the second side 12, the short side on the lower side is the first short side 13, and the short side on the top side is the first side 11. is called the second short side 14. A second body plate 20 and a third body plate 30 are connected to the left and right sides of the first body plate 10, respectively. In the example of FIG. 1, the second body plate 20 is provided on the first side 11 on the left side of the first body plate 10, and the third body plate 30 is provided on the second side 12 on the right side. These first side 11 and second side 12 are mountain-folded, and the third side 21 of the second body plate 20, which is opposite to the first side 11, and the second side 12 of the third body plate 30 are opposite. The fourth side 31 side is joined. For example, a synthetic adhesive, glue, or the like (hereinafter collectively referred to as an adhesive) is applied to the second body plate 20 to adhere the third body plate 30 to the second body plate 20 . As a result, the joint plate 30' in which the third body plate 30 is bonded to the second body plate 20 and the first body plate 10 are formed into a trunk shape or a cylindrical shape, and the second body plate 20 and the joint plate 30 are A pillow-shaped or pupil-shaped storage space SP is formed in the interior facing '.

In the example of Fig. 1, the first body panel 10 and the third body panel 30 have the same width, and the width of the second body panel 20 is shorter than the first body panel 10, for example half, and the second body panel 20 is used as a glue tab. This allows the entire surface of the third body panel 30 to be exposed, making the joint between the second body panel 20 and the third body panel 30 less noticeable and improving the appearance. However, the present invention is not limited to this configuration, and the widths of the second body panel and the third body panel can be designed as desired.
(Break line 40)

Further, the third body plate 30 is formed with a break line 40 that breaks when the stored item is taken out. The adhesive is applied only to the area to be broken so that the joining plate 30' can be broken by breaking at the breaking line 40. In the example of FIG. 1, two breaking lines 40 are formed diagonally from near the center of the right long side of the third body plate 30 toward the middle of the upper and lower short sides. Therefore, when applying the adhesive to the second body plate 20, the first torn piece 45 and the second torn piece 46 of a right triangle that are broken at the break line 40 in the area to be joined to the third body plate 30 are It is applied to the corresponding area. Thereby, by breaking at the break line 40, the connection between the second body plate 20 and the third body plate 30 is released, the storage space SP is exposed, and the stored items can be taken out. According to this configuration, there is no need to take out the stored items from the top 2 or the bottom 1, and in other words, these are closed after the stored items are stored, thereby preventing the stored items from falling out from the top or bottom. By specializing in the structure, it is possible to focus on stably holding stored items.

In the example of FIG. 1, the break line 40 is a first break line 41 formed diagonally from the center of the fourth side 31 on the right side of the third body plate 30 toward the center of the short side at the lower end, and a first break line 41 formed diagonally toward the center of the short side of the third body plate 30. It is composed of two second breaking lines 42 formed diagonally from the center of the fourth side 31 on the right side of the plate 30 toward the center of the short side at the upper end. In addition, at the center of the fourth side 31, a notch 44 is formed around the center of the fourth side 31 so that the center of the fourth side 31 has a dome shape, as a finger hook 43 for easy tearing. are doing. The first break line 41 and the second break line 42 are formed continuously from the edge of the dome-shaped finger rest 43 . Thereby, when breaking, it is possible to put a finger on the finger hook 43 and break continuously at once along the linear first breaking line 41 and second breaking line 42.

As described above, the adhesive that joins the second and third trunk panels 20 and 30 is applied not to the entire surface of the second trunk panel 20, but to the lower left and upper right areas of the third trunk panel 30 in the development view of Figure 1, which correspond to the first and second broken pieces 45 and 46 that are to be joined at the first and second break lines 41 and 42, respectively. This allows the second and third trunk panels 20 and 30 to be released from their connection by breaking the third trunk panel 30 along the break line 40. Furthermore, with fingers still placed on the finger loop 43, following the breaking of the first and second break lines 41 and 42, the third trunk panel 30 can be opened laterally to expose the internal storage space SP by breaking the third flap 33 at the fold line FF3 and the sixth flap 36 at the fold line FF6. If necessary, a break line or half-cut line may be added to facilitate breaking along the fold line FF3 of the third flap 33 and the fold line FF6 of the sixth flap 36.

As shown in FIG. 30, the product storage container 900 according to the comparative example described above is provided with a break section 945 for taking out on the back surface, and by breaking the break section 945 as shown in FIG. 31, the product can be removed from above. It is configured so that it can be taken out. This configuration has the problem that the breaking portion 945 is small, making it troublesome to break, and making it difficult to take out the product. On the other hand, in the product storage container 100 according to the present embodiment, the storage space SP can be largely exposed by breaking the third body plate 30, and there is an advantage that the stored items GD can be easily taken out.

In the example shown in the developed view of FIG. 1, the first breaking line 41 is extended obliquely from the middle of the fourth side 31 of the third body plate 30 toward the middle of the third flap bending line FF3 at the lower end. ing. However, the present invention does not limit the breaking line to such a pattern, and the side surface of the product storage container can be formed in any pattern that makes it easy to break. For example, while extending the first breaking line 41 obliquely from the middle of the fourth side 31 of the third body plate 30 toward the middle of the third flap folding line FF3, the tip thereof reaches the third flap folding line FF3. You can stop earlier. Alternatively, the first break line may also extend from the middle of the fourth side of the third body plate toward the bottom of the second side 12 instead of the third flap fold line. Alternatively, the first breaking line may not be straight, but may be extended halfway toward the middle of the third flap bending line at the lower end, and then bent toward the second side. Further, the second break line can also be formed symmetrically with respect to the horizontal line that bisects the longitudinal direction of the third body plate 30, similarly to the first break line described above. Alternatively, the second break line may be provided asymmetrically with respect to the first break line.
(Bottom 1)

Of the two end faces of the pillow-shaped storage space SP surrounded by the first body panel 10 and the connecting panel 30', the top side is called the top section 2 and the bottom side is called the bottom section 1. The bottom section 1 has an insertion hole 3 formed therein for inserting the item GD to be stored into the storage space SP, as shown in Figure 7. By changing the storage container from its folded state as shown in Figure 10 to its expanded state as shown in Figures 11 and 12, the insertion hole 3 is also expanded in the same way, making it possible to insert the item GD to be stored into the storage space SP from here.

The first body panel 10 has a first flap 50 connected to its lower part. The second body panel 20 has a second flap 22 connected to its lower part. The third body panel 30 has a third flap 33 connected to its lower part. The first flap 50, the second flap 22, and the third flap 33 are each mountain-folded between the lower ends of the first body panel 10, the second body panel 20, and the third body panel 30 to form the bottom 1. Here, the fold line where the first flap 50 is folded back at the first short side 13 at the lower end of the first body panel 10 is called the first flap fold line FF1, the fold line where the second flap 22 is folded back at the lower end of the second body panel 20 is called the second flap fold line FF2, and the fold line where the third flap 33 is folded back at the lower end of the third body panel 30 is called the third flap fold line FF3.
(Third flap 33)

The third flap 33 is provided at the lower end of the third body panel 30, offset toward the second side 12. Preferably, the third flap 33 is formed at approximately 1/2 or less of the width of the lower end of the third body panel 30. In other words, the length of the third flap fold line FF3 is approximately 1/2 or less of the horizontal width of the third body panel 30. More preferably, the third flap 33 is provided at the lower end of the third body panel 30, from the second side 12 to the center of the width of the lower end of the third body panel 30. In other words, the third flap 33 is provided in contact with the second side 12, which is the boundary between the first body panel 10 and the third body panel 30.

On the other hand, the width of the second body plate 20 is approximately 1/2 or less of that of the third body plate 30. Further, the upper end of the second flap 22 is formed to have the same width as the lower end of the second body plate 20. Further, the upper end of the first flap 50 is formed to have the same width as the lower end of the first body plate 10. With such a configuration, when the third body plate 30 and the second body plate 20 are joined to form the joint plate 30', the second flap 22 and the third flap 33 are adjacent to each other on the bottom part 1 without overlapping. , the bottom portion 1 can be formed in a position facing the first flap 50.
(first flap 50)

The first flap 50 includes a first flap body 53, a first folded piece 51, and a second folded piece 52. The first flap body 53 is connected to the left and right sides of the first folded piece 51 and the second folded piece 52. The first flap body 53 and the first folded piece 51, and the first flap body 53 and the second folded piece 52 are each folded in a valley. The first folded piece 51, which is folded in a valley from the first flap body 53, is attached to the second flap 22. The second folded piece 52, which is also folded in a valley from the first flap body 53, is attached to the third flap 33. As shown in Figs. 6 and 8, the bottom 1 forms an insertion hole 3 by expanding the product storage container 100. In order to form the insertion hole 3, the first flap body 53 is formed into an isosceles trapezoid shape with a wide gap between the first folded piece 51 and the second folded piece 52 in the development view of Fig. 1, and further with a chamfered lower end.
(Detent mechanism)

Further, the bottom portion 1 has a detent mechanism to prevent the stored object GD from jumping out from the insertion hole 3 when the stored object GD is stored in the insertion hole 3. The detent mechanism includes a second flap 22, a third flap 33, and a first flap 50. Specifically, the second flap 22 and the third flap 33 are provided by mountain folding along the second flap folding line FF2 and the third flap folding line FF3 at the lower ends of the second body plate 20 and the third body plate 30, respectively. Thus, the second flap 22 and the third flap 33 are separate members. These second flap 22 and third flap 33 are made to face the first flap 50 to form the bottom part 1. As a result, since the second flap 22 and the third flap 33 are separate members, they do not interact with each other, and the bounce becomes large, acting to deform the insertion hole 3 in the direction of closing it, and causing the object to be stored GD to be deformed. Prevent shedding.

For example, in the product storage container 900 according to the comparative example shown in the developed view of FIG. 24, the bottom part 1 is made up of two flaps 950 and 960 that are formed by folding the lower ends of the two body plates 910 and 930 into mountain folds along folding lines FD2. is formed. When a cylindrical product is stored in the product storage container 900 that forms the storage space SP between the two body plates 910 and 930, the two body plates 910 and 930 become pillowed as shown in FIG. The product storage container 900 swells into a shape, and the center portion is pushed up from the inner surface and pressure is applied, resulting in a state in which a crease FD1 is formed in the longitudinal direction of the product storage container 900.

Generally, in the flaps 950 and 960, which are obtained by folding the lower ends of the body plates 910 and 930, a repulsive force acts on the folded portions to return to the original state before folding. By utilizing this repulsive force, as shown in FIGS. 28 and 29, after the product is press-fitted into the storage space SP, the flaps 950 and 960 are biased in the direction of closing the insertion hole 903, and the product is inserted. This prevents it from falling through the hole 903.

However, according to the tests conducted by the inventor of the present application, in the pillow-shaped storage space SP as described above, the lower ends of the body plates 910 and 930 are expanded at the center by storing the product, and as a result, the product storage container 900 A crease FD1 is likely to form in the longitudinal direction. This fold line FD1 is perpendicular to the fold line FD2 where the lower ends of the body plates 910 and 930 are bent. When the folds intersect in this way, the repulsive force that causes the flaps 950, 960 bent at the fold line FD2 to return to their original state is significantly reduced. Note that even if the product storage container does not have a clear crease along its longitudinal direction, the repulsive force is similarly impaired even if it is in a curved state. In other words, as a result of the repulsive force being reduced, the flaps 950 and 960 do not close neatly after press-fitting the product and remain open, causing the problem that the product is likely to fall out, as shown in Figure 29. There was found. In particular, in the configuration in which the product is inserted from the bottom of the product storage container 900 as shown in FIG. 28, since the insertion hole 903 is formed on the bottom side, there is a problem in that the product tends to come out naturally due to gravity due to the structure. .

In contrast, in the product storage container 100 according to the present embodiment, the bottom 1 does not have two flaps facing each other as described above, but has three flaps, one of which is made of a separate material. With this configuration, even if the bottom 1 is expanded as shown in Figures 11 and 12 from the folded state of the product storage container 100 as shown in Figure 10, and a fold FD1 is formed or curved in the longitudinal direction of the joining plate 30' joining the second body panel 20 and the third body panel 30, the second flap 22 and the third flap 33 are divided into separate materials and the division position is the center part corresponding to the fold FD1, so that the flaps do not directly intersect with the second flap folding line FF2 and the third flap folding line FF3 at which the flaps are folded back, and thus damage to the repulsive force can be avoided. As a result, after the repulsive force of the second flap 22 and the third flap 33 is exerted to press the stored item GD into the storage space SP, the second flap 22 and the third flap 33 attempt to bend in a direction perpendicular to the joint plate 30' due to the repulsive force that causes them to return to their original state. In other words, the second flap 22 and the third flap 33 can be deformed in a direction that narrows the insertion hole 3 and act as a return stop mechanism, thereby stably holding the stored item GD in the storage space SP and improving reliability.
(First through hole 54)

In addition, the product storage container 100 shown in FIG. 1 has a detent mechanism added to the first flap 50 side as well. That is, the first flap main body 53 forms a first through-hole 54, and is provided with a first folding line 56, a second folding line 57, and a first intermediate folding line 55 extending from the first through-hole 54. . The first through hole 54 is formed at the center of the first flap 50 in the width direction. If the bending line has corners, it will cause tension and the repulsive force will be reduced; however, by forming a through hole, the corner can be eliminated and the tension can be reduced. Here, the first through hole 54 is semicircular and formed so that the diameter of the edge matches the second short side 14 .

The first fold line 56 extends from the first through opening 54 toward the first folded piece 51 side of the edge of the first flap body 53. In the example of FIG. 1, it extends diagonally downward to the left from the left side of the arc of the first through opening 54.

On the other hand, the second folding line 57 extends from the first through-hole 54 toward the second folding piece 52 side of the edge of the first flap body 53. In the example of FIG. 1, it extends diagonally downward to the right from the right side of the arc of the first through hole 54.

Furthermore, the first intermediate fold line 55 extends from the first through opening 54 toward the center of the edge of the first flap body 53. In the example of FIG. 1, it extends vertically from the apex of the arc of the first through opening 54. This first intermediate fold line 55 is provided between the first fold line 56 and the second fold line 57. Preferably, the first fold line 56 and the second fold line 57 are provided line-symmetrically with respect to the first intermediate fold line 55. Furthermore, the first fold line 56 and the second fold line 57 are mountain folds, while the first intermediate fold line 55 is a valley fold.

Further, the first flap main body 53 is cut out at the end edge of the first intermediate folding curve 55 extending from the first through-hole 54 so as to be recessed in a V-shape. In the example of FIG. 1, the lower end of the first flap 50 is recessed from the horizontal line into a chamfered isosceles trapezoid shape, and further protrudes in the shape of a chevron at the center, so that the top becomes the widthwise center of the first flap 50, Moreover, a first intermediate bending curve 55 is provided at the top of this. The shape of the first flap 50, including the first folding piece 51 and the second folding piece 52, is formed line-symmetrically about the first intermediate folding curve 55. Here, the left side of the first flap 50 with the first intermediate bending curve 55 as a border is called a first flap left region 50a, and the right side is called a first flap right region 50b. The first flap left region 50a and the first flap right region 50b are continuously formed as one sheet, but are bent along a first intermediate folding curve 55, and a crease is formed in advance. This first intermediate folding line 55 has a first through-hole 54 at its upper end, and is recessed in a V-shape at the top at its lower end, and is narrower at the top and bottom, so that the first intermediate folding line 55 is bent. The resistance force is weakened, making it easier to bend. In other words, although the first flap 50 itself is constructed as a single piece, it is structured such that the first flap left region 50a and the first flap right region 50b are separated by the first intermediate folding curve 55. . In such a first flap 50, since the interaction between the first flap left region 50a and the first flap right region 50b becomes difficult to reach, the first flap left region 50a and the first flap right region 50b each have a first flap In the state of folding back along the flap folding line FF1, it becomes easier to exert a repulsive force to return to the original state before folding. In other words, the repulsive force is inhibited by the interaction between the left and right sides when the fold line is perpendicular to the fold line and one flap continues integrally on the left and right sides along the fold line. On the other hand, by weakening the interaction between the left and right sides, it is possible to make it easier for the left and right sides to move independently, thereby suppressing the inhibitory effect.

When the stored item GD is stored through the insertion hole 3 of the product storage container 100 and the internal space is expanded into a pillow shape, the first intermediate folding curve 55 is valley-folded and the first mountain-folded first The folding line 56 and the second folding line 57 are moved closer to each other. In this state, even if a crease is formed along the longitudinal direction of the first body plate 10 as shown in FIGS. 11 and 12, the first intermediate fold line 55 bent in the opposite direction, As a result of dividing the first flap left region 50a and the first flap right region 50b by the curve 56 and the second folding curve 57, each of the first flap left region 50a and the first flap right region 50b tries to return to the state before folding. This makes it easier to exert repulsive force. As a result, on the first flap main body 53 side as well, it is possible to exert a detent mechanism that prevents the stored object GD from falling out of the storage space SP after being stored.

In addition, the angle between the first intermediate fold line 55 and the first fold line 56 is preferably equal to the angle between the first intermediate fold line 55 and the second fold line 57. More preferably, it is set to 20° or more. With this configuration, the adjacent fold lines, that is, the first intermediate fold line 55 and the first fold line 56, and the first intermediate fold line 55 and the second fold line 57, can be easily folded, and processing precision can be maintained.
(Heaven 2)

On the other hand, the top portion 2 is closed even when the product storage container 100 is expanded, thereby preventing foreign matter from entering the storage space SP and protecting the stored items GD.
(Header section 70)

Further, a header portion 70 may be provided on the top portion 2 side of the first body plate 10. In the example shown in the developed view of FIG. 1, the lower end of the first body plate 10 is aligned with the lower end of the second body plate 20 and the lower end of the third body plate 30. Further, the upper end of the second body plate 20 is aligned with the upper end of the third body plate 30. In other words, the second body plate 20 and the third body plate 30 have the same height. On the other hand, the upper end of the first body plate 10 is made to protrude more than the upper ends of the second body plate 20 and the third body plate 30. That is, the first body plate 10 is formed longer than the second body plate 20 and the third body plate 30 in the vertical direction. This first body plate 10 forms a header bending line HF1 between its upper end and the extension line of the upper ends of the second body plate 20 and the third body plate 30. By mountain-folding the header along the header folding line HF1 and valley-folding it along the fourth flap folding line FF4 at the upper end of the first body plate 10, the header is made to protrude beyond the joining plate 30' as shown in FIGS. 2 and 3. A section 70 is formed. By providing the header portion 70 in which the first body plate 10 protrudes beyond the joining plate 30' in this manner, a large area on the front side of the product storage container 100 can be secured. For example, the appearance can be improved by providing a large printed surface for product explanations on the front side of the product storage container 100. Further, on the back side of the header portion 70, the top portion 2 can be formed by the fourth flap 60, the fifth flap 25, and the sixth flap 36 as described above.

In order to facilitate the formation of the header portion 70, cutouts are formed on the left and right sides of the position where the header bending line HF1 is provided in the upper part of the first body plate 10. Thereby, the upper end of the first body plate 10 can be easily folded back. Here, in the exploded view of FIG. 1, the area above the header folding line HF1 and below the fourth flap folding line FF4 is the header back panel 72, and the area below the header folding line HF1 and overlapping with the header back panel 72 is shown below. , is called a header table panel 71. By overlapping the header back panel 72 on the back side of the header front panel 71, the header portion 70 can be constructed in a double structure and its strength can be increased.

The first body panel 10 has a fourth flap 60 connected to its upper part. The second body panel 20 has a fifth flap 25 connected to its upper part, and the third body panel 30 has a sixth flap 36 connected to its upper part. The fifth flap 25 and the sixth flap 36 are mountain-folded at the upper ends of the second body panel 20 and the third body panel 30, respectively, while the fourth flap 60, which has already been mountain-folded at the header fold line HF1 at the upper part of the first body panel 10, is valley-folded at its upper end to form the top section 2. Here, the fold line where the fourth flap 60 is folded back at the second short side 14 at the upper end of the first body panel 10 is called the fourth flap fold line FF4, the fold line where the fifth flap 25 is folded back at the upper end of the second body panel 20 is called the fifth flap 25 fold line FF5, and the fold line where the sixth flap 36 is folded back at the upper end of the third body panel 30 is called the sixth flap 36 fold line FF6. In the bottom part 1, the first flap fold line FF1, the second flap fold line FF2, and the third flap fold line FF3 are aligned in a straight line, but in the top part 2, the fifth flap 25 fold line FF5 and the sixth flap 36 fold line FF6 are aligned in a straight line, while the fourth flap fold line FF4 protrudes beyond the fifth flap 25 fold line FF5 and the sixth flap 36 fold line FF6.
(Sixth flap 36)

The sixth flap 36 is also provided unevenly distributed on the second side 12 side at the upper end of the third body plate 30. Preferably, the sixth flap 36 is formed to be approximately 1/2 or less of the width of the upper end of the third body plate 30. That is, the length of the sixth flap 36 bending line FF6 is about 1/2 or less of the width of the third body plate 30. In the example of FIG. 1, the third body plate 30 is formed in a rectangular shape with equal width, so the length of the sixth flap 36 folding line FF6 is equal to the third flap folding line FF3. More preferably, at the upper end of the third body plate 30, a sixth flap 36 is provided at a position from the second side 12 to the width center of the upper end of the third body plate 30. That is, the sixth flap 36 is provided in contact with the second side 12 that is the boundary between the first body plate 10 and the third body plate 30.

On the other hand, the lower end of the fifth flap 25 provided at the upper end of the second body plate 20 is formed to have the same width as the lower end of the second body plate 20. Further, the lower end of the fourth flap 60 is formed to have the same width as the upper end of the first body plate 10. With such a configuration, when the third body plate 30 and the second body plate 20 are joined to form the joint plate 30', the fifth flap 25 and the sixth flap 36 are adjacent to each other without overlapping on the top part 2. Thus, the top portion 2 can be formed in a position facing the fourth flap 60.
(Fourth flap 60)

Further, the fourth flap 60 includes a fourth flap main body 63, a third bent piece 61, and a fourth bent piece 62. The fourth flap main body 63 has a third bent piece 61 and a fourth bent piece 62 connected to each other on its left and right sides. The fourth flap main body 63 and the third folded piece 61, and the fourth flap main body 63 and the fourth folded piece 62 are each mountain-folded. The third bent piece 61 that is mountain-folded from the fourth flap main body 63 is attached to the fifth flap 25. Similarly, the fourth folded piece 62, which is mountain-folded from the fourth flap main body 63, is attached to the sixth flap 36. The top portion 2 is closed by expanding the product storage container 100, as shown in FIGS. 14 and 15.
(Closure mechanism)

Similar to the return prevention mechanism provided on the bottom 1, the storage space SP is provided with a closing mechanism that closes the top 2 to prevent foreign objects from entering the storage space SP when the stored object GD is stored in the storage space SP. The closing mechanism is composed of a fifth flap 25, a sixth flap 36, and a fourth flap 60. Specifically, the fifth flap 25 and the sixth flap 36 are mountain-folded at the folding line FF5 of the fifth flap 25 and the folding line FF6 of the sixth flap 36 at the upper ends of the second body panel 20 and the third body panel 30, respectively, so that the fifth flap 25 and the sixth flap 36 become separate members. The fifth flap 25 and the sixth flap 36 are opposed to the fourth flap 60 to form the top 2. As a result, since the fifth flap 25 and the sixth flap 36 are separate members, they do not interact with each other, but rather jump up more and act to deform in a direction to close the top, preventing the intrusion of foreign objects from the top.
(Second through hole 64)

In addition, the product storage container 100 in FIG. 1 also has a closing mechanism on the fourth flap 60 side. That is, the fourth flap body 63 forms a second through opening 64, and is provided with a third fold line 66, a fourth fold line 67, and a second intermediate fold line 65 extending from the second through opening 64. The second through opening 64 is formed in the center of the width direction of the fourth flap 60. The second through opening 64 may be formed in a semicircular shape, similar to the first through opening 54. In the example of the development view in FIG. 1, the second through opening 64 is an elongated hole and is used in combination with the fifth through opening 74 described later. That is, the second through opening 64 is formed so as to overlap with the fourth through opening 73 by overlapping the header back panel 72 on the back side of the header front panel 71.

The third fold line 66 extends from the second through opening 64 along the edge of the third folded piece 61 at the edge of the fourth flap body 63. In the example of FIG. 1, it extends diagonally upwards to the left from the left side of the arc of the second through opening 64.

On the other hand, the fourth fold line 67 extends from the second through opening 64 toward the fourth folded piece 62 side of the edge of the fourth flap body 63. In the example of FIG. 1, it extends diagonally upwards to the right from the right side of the arc of the second through opening 64.

The second intermediate fold line 65 extends from the second through opening 64 toward the center of the edge of the fourth flap body 63. In the example of FIG. 1, it extends vertically from the apex of the arc at the upper end of the second through opening 64. The second intermediate fold line 65 is provided between the third fold line 66 and the fourth fold line 67. Preferably, the third fold line 66 and the fourth fold line 67 are provided symmetrically with respect to the second intermediate fold line 65. The third fold line 66 and the fourth fold line 67 are mountain folds, while the second intermediate fold line 65 is a valley fold.

Further, the fourth flap main body 63 is cut out at the end edge of the second intermediate folding curve 65 extending from the second through-hole 64 so as to be recessed in a V-shape. In the example of FIG. 1, the upper end of the fourth flap 60 has a third bent piece 61 and a fourth bent piece 62 provided on the left and right sides thereof projecting in a mountain shape, and the third bent piece 61 and the fourth bent piece The middle of the folded piece 62 is recessed in the shape of an inverted isosceles trapezoid, and the center thereof is further recessed in a V-shape, so that the top becomes the center in the width direction of the fourth flap 60, and a second intermediate fold curve is formed at the top. The upper ends of 65 are aligned. The shape of the fourth flap 60, including the third folding piece 61 and the fourth folding piece 62, is formed line-symmetrically about the second intermediate folding curve 65. Here, the left side of the fourth flap 60 with the second intermediate bending curve 65 as a border is called a fourth flap left region 60a, and the right side is called a fourth flap right region 60b. The fourth flap left region 60a and the fourth flap right region 60b are continuously formed as one sheet, but are bent along a second intermediate folding curve 65, and a crease is formed in advance. This second intermediate folding curve 65 has a second through hole 64 at the lower end, and a V-shaped recess at the top of the upper end, and is narrowed at the top and bottom, so that the second intermediate folding curve 65 is bent. The resistance force is weakened, making it easier to bend. In other words, although the fourth flap 60 itself is configured as a single piece, it is configured such that the fourth flap left region 60a and the fourth flap right region 60b are separated by the second intermediate folding curve 65. . In such a fourth flap 60, since the interaction between the fourth flap left region 60a and the fourth flap right region 60b becomes difficult to reach, the fourth flap left region 60a and the fourth flap right region 60b each have a fourth flap In the state of folding back along the flap folding line FF4, it becomes easier to exert a repulsive force to return to the original state before folding. As mentioned above, the repulsive force is inhibited by the interaction between the left and right sides when the fold line is perpendicular to the fold line and one flap is integrally continuous on the left and right sides along the fold line. By weakening the interaction between the left and right sides, it is possible to make it easier for the left and right sides to move independently, thereby suppressing the inhibitory effect.

The angle between the second intermediate fold line 65 and the third fold line 66 is preferably equal to the angle between the second intermediate fold line 65 and the fourth fold line 67. More preferably, it is 20° or more. This configuration makes it easier to fold the adjacent fold lines, the second intermediate fold line 65 and the third fold line 66, and the second intermediate fold line 65 and the fourth fold line 67, and maintains processing precision.

Furthermore, it is preferable to make the angle between the first intermediate fold line and the first fold line 56 larger than the angle between the second intermediate fold line 65 and the third fold line 66. By doing so, the bottom 1 side can be expanded more to make it easier to store items, and even after storage, the bottom 1 side can be expanded more than the top 2 side, making the bottom 1 side wider as shown in Figure 4 and making the product storage container closer to a triangular shape in side view, making it easier to stand stably.

In this way, by providing flaps on both the top 2 and bottom 1 and configuring each side to be closed, the storage space SP can be expanded not only on the bottom 1 but also on the top 2 side as well, which has the advantage of making it easier to store stored items GD, compared to a configuration in which flaps are provided only on the bottom. In particular, in the product storage container 100 of the comparative example shown in Figure 27, etc., flaps are provided only on the bottom surface and the top is glued together, so the top is not pillow-shaped but has a distorted shape. In contrast, in the product storage container 100 of this embodiment, both the top and bottom are pillow-shaped, improving the appearance.

On the other hand, from the viewpoint of making the product storage container 100 independent, it is preferable to expand the bottom 1 side more than the top 2 side. As a result, as shown in FIG. 4, the bottom 1 can be made wider to approximate a triangular shape and the center of gravity can be stabilized. Therefore, in a state in which the stored object GD is stored through the insertion hole 3, the third folding piece 61 and the fourth folding piece 62 are bent toward the back side of the end surface of the top portion 2. Further, as the thickness of the stored item increases, the angle between the third folding piece 61 and the fourth folding piece 62 and the end surface of the top part 2 becomes shallower. With such a configuration, even if the stored item is thin, it can be absorbed and stably held by varying the inclination angle of the top portion 2. Further, the angles between the third folding piece 61 and the fourth folding piece 62 and the end surface of the top portion 2 may be adjusted depending on the thickness of the item to be stored.
(Pinch mechanism)

Further, a pinching mechanism may be configured to stably hold the stored object GD in the storage space SP. As a pinching mechanism, the product storage container 100 according to the first embodiment has a lower pinching space 76 formed in the bottom portion 1, as shown in FIG. Specifically, the second flap 22 forms a second flap stepped portion 22a on the side facing the third flap 33 in the storage space SP. Further, the third flap 33 forms a third flap stepped portion 33a on the side facing the second flap 22 in the storage space SP. A lower sandwiching space 76 is formed between the second flap stepped portion 22a and the third flap stepped portion 33a, in which the lower end of the stored object GD is sandwiched from both sides. The lower sandwiching space 76 is designed according to the size of the lower end of the stored object GD. That is, by sandwiching the lower end of the stored object GD from the left and right between the second flap step portion 22a and the third flap step portion 33a, it is possible to stably hold the object GD. In particular, when a cylindrical stored object GD is stored in a storage space SP having a pillow-shaped cross section, spaces are formed on the left and right sides of the stored object GD, making it easy to shift left and right, making the position unstable. Therefore, by using the second flap 22 and the third flap 33 and sandwiching the left and right sides of the stored object GD between the second flap stepped portion 22a and the third flap stepped portion 33a, it is possible to stably hold the stored object GD. Benefits can be obtained.

The second flap step portion 22a and the third flap step portion 33a are formed by cutting out the edges of the second flap 22 and the third flap 33, as shown in the developed view of FIG. The second flap step portion 22a and the third flap step portion 33a are formed line-symmetrically with respect to the first body plate 10.

The clamping mechanism may be provided in the top part 2 instead of or in addition to the bottom part 1. The product storage container 100 according to the first embodiment also forms an upper clamping space 77 in the top part 2 as shown in FIG. 16. Specifically, the fifth flap 25 forms a fifth flap step part 25a on the side facing the sixth flap 36 in the storage space SP. The sixth flap 36 also forms a sixth flap step part 36a on the side facing the fifth flap 25 in the storage space SP. Between the fifth flap step part 25a and the sixth flap step part 36a, an upper clamping space 77 is formed that clamps the upper end of the stored item GD from both sides. With this configuration, when the stored item GD is stored in the pillow-shaped storage space SP, the fifth flap step part 25a and the sixth flap step part 36a clamp the upper end of the stored item GD, so that the stored item GD can be stably held. The fifth flap step 25a and the sixth flap step 36a are also formed by cutting out the edges of the fifth flap 25 and the sixth flap 36, as shown in the development view of Figure 1. These fifth flap step 25a and sixth flap step 36a are also formed symmetrically with respect to the first body panel 10.

By providing the pinching mechanism in the bottom part 1 and the top part 2 in this way, the stored object GD can be held in the storage space SP more stably. Note that the pinching mechanism between the bottom portion 1 and the top portion 2 may be formed in the same shape or may be formed in different shapes. Each pinching mechanism is designed according to the shape of the object to be stored GD, etc. In the example shown in the developed view of FIG. 1, the shapes of the second flap 22 and third flap 33 of the bottom part 1 and the fifth flap 25 and sixth flap 36 of the top part 2 are made different.
(joint surface)

As described above, the fourth flap 60 is partially attached to the fifth flap 25 and the sixth flap 36 to form the top portion 2. Here, by increasing the area of the third folded piece 61 attached to the fifth flap 25 and the fourth folded piece 62 attached to the sixth flap 36 of the fourth flap 60, the fourth flap By increasing the applied area of the adhesive for joining 60 to the fifth flap 25 and the sixth flap 36, more stable joining can be achieved.

For this reason, the fourth flap 60 has a third boundary line 68 between the fourth flap main body 63 and the third folded piece 61 not formed in a straight line, but formed with a first cut 68a curved toward the first body panel 10. Similarly, a fourth boundary line 69 between the fourth flap main body 63 and the fourth folded piece 62 not formed in a straight line, but formed with a second cut 69a curved toward the first body panel 10. The back side of the first cut 68a is a first joining surface 68b for joining the third folded piece 61 to the fifth flap 25, and the back side of the second cut 69a is a second joining surface 69b for joining the fourth folded piece 62 to the sixth flap 36. In this way, by widening the areas of the first joining surface 68b and the second joining surface 69b, the area of the margin for applying adhesive is secured, and strength can be maintained while the third boundary line 68 and the fourth boundary line 69 are formed at acute angles.
(Fracture Area)

The bottom 1 also has a judgment area to balance ease of storing the item GD and maintaining the strength of the bottom 1 when it is molded. The larger the insertion hole 3 formed in the bottom 1, the easier it is to insert the item GD and the larger the item GD that can be stored. On the other hand, if the insertion hole 3 is made larger, the first flap 50 that constitutes the bottom 1 becomes relatively small, making molding errors more likely to occur and making it difficult to mold with sufficient strength. Thus, when forming the insertion hole 3 in the bottom 1, there is a tradeoff between ease of storing the item GD and maintaining the strength of the bottom 1 when it is molded, making it difficult to balance these two.

On the other hand, in the product storage container 100 according to the first embodiment, the break area is provided so that the insertion hole 3 is formed small during molding, but the insertion hole 3 is enlarged when the stored object GD is inserted. Specifically, as shown in FIGS. 1, 6, etc., the first flap 50 forms a first through slit 58a at a first boundary line 58 with the first bent piece 51. Further, a first breakage region 58b is formed between the first through slit 58a and the edge of the first flap 50. The first breakage region 58b is preferably made to be easily broken by providing a half cut or adding a perforation line.

On the other hand, the first flap 50 forms a second through slit 59a at the second boundary line 59 with the second folded piece 52. A second break region 59b is also formed between the second through slit 59a and the edge of the first flap 50. As with the first break region 58b, the second break region 59b is also preferably made easier to break by providing a half cut or adding a cut line.

The first breaking area 58b and the second breaking area 59b are configured to break when the stored item GD is inserted from the bottom 1. With such a configuration, when manufacturing the product storage container 100, the first flap 50, the first folding piece 51, and the second folding piece 52 are separated by the first breaking area 58b and the second breaking area 59b. While exhibiting connection strength, the first breaking region 58b and the second breaking region 59b can be broken by press-fitting when storing the stored object GD. This makes it possible to reduce the size of the insertion hole 3 and exhibit strength, while also storing a larger object GD.
(Opening window 75)

Furthermore, the first body panel 10 may have an opening window 75 formed in the middle thereof, through which part of the stored item GD is exposed when the item GD is stored therein. This allows a product storage container 100 to be realized in which part of the stored item GD is exposed through the opening window 75, making the stored item GD visible from the outside, as shown in FIG.
[Embodiment 2]

The opening window 75 may have any shape such as a vertical track shape, a rectangular shape, a polygonal shape such as a trapezoid shape, a diamond shape, an ellipse shape, a star shape, a heart shape, or the like. In the case of a polygonal shape, it is preferable to chamfer the corners. A product storage container 200 according to the second embodiment shown in FIG. 17 has a vertically long inverted isosceles trapezoid shape with a chamfered opening window 75B. In this figure, members similar to those in the first embodiment described above are given the same reference numerals and detailed explanations are omitted.
[Embodiment 3]

The formation of the opening window 75 is optional, and the first body panel 10 may be configured without an opening window. Such an example is shown in the development diagram of FIG. 18 as a product storage container 300 according to embodiment 3. In this diagram, the same components as those in embodiment 1 described above are given the same reference numerals, and detailed explanations are omitted as appropriate. In the product storage container 300 according to embodiment 3, the first body panel 10 is a uniform flat plate.

Note that the above-mentioned pinching mechanism is also not essential, and may be provided only on either the top or the bottom, or both may be omitted. In the example of FIG. 18, a lower sandwiching space is formed only at the bottom, and an upper sandwiching space is not provided at the top.
(Guide panel 75b)
[Embodiment 4]

The opening window 75 may also have guide panels formed on the left and right sides. Such an example is shown in the development diagram of FIG. 19 as a product storage container 400 according to embodiment 4. In this diagram, the same components as those in embodiment 1 above are given the same reference numerals and detailed descriptions are omitted as appropriate. The product storage container 400 according to embodiment 4 has a vertically long opening window 75D with a semicircular upper portion and a flat lower portion formed near the center of the first body panel 10, and guide panels 75b extending from the left and right sides of the inner shape of the opening window 75D toward the center from the middle to the bottom of the opening window 75D. Each guide panel 75b abuts at the center of the first body panel 10. This opening window 75D is formed by forming a sixth through hole 75Da in the middle of the first body panel 10, forming a seventh through hole 75Db spaced below it, forming a cut line 75Dc from the center of the width of the sixth through hole 75Da to the center of the width of the seventh through hole 75Db, and further forming folding lines 75Dd from the lower right and lower left of the sixth through hole 75Da to the upper right and upper left of the seventh through hole 75Db.

As shown in Fig. 20, the product storage container 400 according to the fourth embodiment is separated into left and right guide panels 75b at the cut line 75Dc before inserting the stored item GD, and is folded in a double-door shape at the left and right folding lines 75Dd to guide the left and right sides of the opening window 75D. In this state, the stored item GD is inserted into the storage space SP from the insertion hole 3, and is inserted into the guide space guided on both sides by the guide panels 75b. In this state, the stored item GD is pressed on the left and right sides by the guide panels 75b and stably held.
(Hanging hole)

Further, a hanging hole for hanging the product storage container 100 may be provided in the header portion 70. In the example shown in the exploded view of FIG. 1, the first body plate 10 forms the fourth through hole 73 at a position spaced downward from the header bending line HF1. Further, a fifth through hole 74 is formed at a position spaced upward from the header bending line HF1. The fourth through hole 73 is formed in the header front panel 71. Further, the fifth through hole 74 is formed in the header back panel 72. By folding back the upper part of the first body plate 10 along the header bending line and stacking the header back panel 72 on the back side of the header front panel 71, the fourth through hole 73 and the fifth through hole 74 are overlapped, and the through hole A hanging hole is formed. By hanging this hanging hole from a hook or the like, it becomes possible to hang and display the product storage container 100. In particular, since the header section 70 has a double structure in which the header front panel 71 and the header back panel 72 are stacked, the hanging holes are also double, and the strength during hanging can be improved.

Furthermore, it is preferable that the fifth through-hole 74 is formed into an elongated hole, and a portion thereof is shared with the second through-hole 64 . Thereby, the hanging hole and the closing mechanism hole can be made common, and the configuration can be simplified.

Note that it is not necessarily necessary to provide a hanging hole in the header portion 70. For example, in the product storage container 400 according to the fourth embodiment described above, an example is shown in which the header portion 70 is not provided with a hanging hole.
[Embodiment 5]

Furthermore, it is not necessarily necessary to provide the header portion 70 of the product storage container. For example, a product storage container 500 according to the fifth embodiment shown in the plan view of FIG. 21 does not have a header portion. In this configuration, the heights of the first body plate 10E, the second body plate 20E, and the third body plate 30E are equal. Further, at the bottom 1E, the first flap folding line FF1, the second flap folding line FF2, and the third flap folding line FF3 are aligned in a straight line, and at the top 2E, the fifth flap 25 folding line FF5, the fourth flap folding line FF4, The sixth flap 36 bending line FF6 is aligned in a straight line.
[Embodiment 6]

As described above, in the configuration in which flaps are provided on both the top 2 and the bottom 1 to close each side, the insertion hole 3 can be provided not only in the bottom 1 but also in the top 2. Such an example is shown in the developed view of FIG. 22 as a product storage container 600 according to the sixth embodiment. In this figure as well, members similar to those in the first embodiment and the like described above are given the same reference numerals and detailed explanations are omitted as appropriate.

The product storage container 600 according to the sixth embodiment has a second insertion hole 3' formed in the top portion 2F. For this reason, the fourth flap body 63F is formed in an inverted isosceles trapezoid shape with a wide gap between the third folded piece 61F and the fourth folded piece 62F and a chamfered upper end. The fourth flap 60F may be formed in the same shape as the first flap 50, or may be formed in a different shape. By forming the second insertion hole 3' in the top portion 2F, the stored item can be inserted not only through the insertion hole 3 in the bottom portion 1 but also through the top portion 2F, increasing the degree of freedom for box making machines, automatic filling machines, and the like.
[Embodiment 7]

Further, it is not necessarily necessary to provide a break area in the insertion hole, and the break area may be omitted. Such an example is shown in the developed view of FIG. 23 as a product storage container 700 according to the seventh embodiment. In this figure as well, members similar to those in the first embodiment and the like described above are given the same reference numerals and detailed explanations are omitted as appropriate.

In the product storage container 700 according to the seventh embodiment, the first flap 50G at the bottom 1G forms a first boundary line 58G between the first flap body 53G and the first bent piece 51G without forming a first through slit, It is a valley fold line. Similarly, the second boundary line 59 between the first flap main body 53G and the second bent piece 52G is also formed as a valley fold line without forming a second through slit. Furthermore, in the top portion 2G, the fourth flap main body 63G does not form a through slit at the third boundary line 68G with the third bent piece 61G and the fourth boundary line 69G with the fourth bent piece 62G. It is a valley fold line. Thereby, it becomes possible to insert objects of specified sizes into the insertion hole 3G and the second insertion hole 3'G, respectively.

Furthermore, the product storage container may have an insertion hole not provided at the bottom but only at the top.

The product storage container of the present invention can be ideally used as packaging for cosmetics, clothing, food, etc.
