Description

  The present invention relates to a partition for storing a plurality of bottles in a cubic or rectangular parallelepiped packaging box in a state of being separated from each other, and a packaging box provided with the partition, and in particular, the packaging box has side and bottom surfaces. The present invention relates to a partition that can effectively prevent breakage of a bottle when dropped from a container, and a packaging box provided with this partition.

  In the field of pharmaceuticals and the like, in order to store a glass vial or the like in a packaging box in a state of being separated, an inner partition obtained by three-dimensionally folding paperboard punched into a predetermined shape is used. This inner partition plays a role of arranging a plurality of bottles in a separated state in the packaging box in a separated state and preventing breakage due to contact between the bottles during transportation. Furthermore, some conventional partitions have been designed to prevent damage to the bottles by absorbing the impact when the packaging box is accidentally dropped.

  For example, in Japanese Patent Application Laid-Open No. 11-35081 (Patent Document 1), by providing a buffer bottom plate on which the bottom of the bottle is placed below the upper partition plate and the lower partition plate that support the body of the bottle. Proposed a partition with a configuration in which a buffer space is formed between the buffer bottom plate and the bottom plate located at the bottom, and tongue pieces reaching the bottom plate are connected to the left and right sides of the upper partition plate located at the top. Has been.

  In such a partition of Patent Document 1, by forming a buffer space under the buffer bottom plate on which the bottom of the bottle is placed, the bottom of the bottle and the bottom of the packaging box are separated, and the packaging box is separated from the bottom. The impact of falling is prevented from acting directly on the bottle. In this case, the tongue piece reaching the bottom plate from the upper partition plate serves to maintain the buffer space against an impact at the time of dropping.

  Japanese Patent Laid-Open No. 7-300156 (Patent Document 2) proposes a partition having a configuration in which the buffer space is provided above and below the bottle storage unit. The inner partition is provided with a hollow cylindrical canopy portion (buffer space) above the bottle storage portion, and a protrusion is provided below the bottle storage portion to form a buffer space between the bottom of the packaging box. It has a configuration. In such a partition of Patent Document 2, the impact when the packaging box falls from the bottom surface is reduced in the upper and lower buffer spaces.

  Furthermore, Japanese Patent Laid-Open No. 2003-292031 (Patent Document 3) proposes a partition that separates the bottom of the bottle and the bottom of the packaging box with a simpler configuration than the above-described buffer space. This middle partition is provided with a vertical support plate standing between a horizontal top plate and a bottom plate forming the bottle storage, and an insertion hole for supporting the bottle body is formed on the top plate. In addition, the support plate is provided with a horseshoe-shaped hole located in the region of the insertion hole.

In such a partition of Patent Document 3, when the bottle is inserted into the insertion hole of the top plate, the bottom of the bottle is supported by the lower edge of the horseshoe-shaped hole. Thereby, the bottom of the bottle and the bottom surface of the packaging box are separated from each other, and even when the packaging box falls from the bottom surface, the impact does not directly act on the bottle.
Japanese Patent Laid-Open No. 11-35081 ([0019], FIGS. 6 and 7) Japanese Unexamined Patent Publication No. 7-300156 ([0021], FIGS. 1 and 5) JP 2003-292031 A ([0019], FIG. 1 and FIG. 2)

  However, all of the above-described conventional partitions are designed to alleviate the impact when the packaging box falls from the bottom surface by separating the bottom of the bottle and the bottom surface of the packaging box, and the packaging box falls from the side surface. In such a case, there is a problem that the bottle cannot be broken.

  In other words, when a packaging box placed on a placement surface such as a medicine shelf or a desk actually falls on the floor or the like, it must fall from the bottom surface of the packaging box that is in surface contact with the placement surface until just before dropping. In many cases, the orientation of the packaging box changes immediately before dropping, and the surfaces other than the bottom face fall downward. Contrary to this fact, the conventional partition has a configuration that focuses only on the case where the packaging box falls from the bottom surface, so that there is still a problem that the bottle is damaged by the fall of the packaging box. .

  Therefore, as a result of intensive studies by the present inventors, it has been found that in the conventional partition, the bottle is easily damaged when the packaging box falls from the side surface. When the inventor conducted a drop test using the conventional partition 100 shown in FIG. 5A, when a packaging box (not shown) using such a partition 100 falls from the side, As shown in FIG. 5B, the upper partition plate 110 and the lower partition plate 111 that support the bottle 3 and the placement plate 112 on which the bottle 3 is placed are greatly curved by an impact when it collides with the floor or the like. (The reference numerals 110a and 111a in the figure indicate the upper support hole and the lower support hole that support the bottle 3).

  In particular, the upper partition plate 110, the lower partition plate 111, and the placement plate 112 in the vicinity of the side surface of the packaging box are severely curved as indicated by the white arrows in FIG. In some cases, tearing and peeling occurred. As a result, the bottle 3 may fall off from one or both of the upper partition plate 110 and the lower partition plate 111, and may be damaged by impact when colliding against the floor or the collision between the bottles 3.

  In addition to this, in the conventional partition 100, the mounting plate 112 on which the bottom of the bottle 3 is placed is easy to bend. Therefore, when the packaging box falls from the bottom and collides with the floor or the like, There is also a problem that the mounting plate 112 is forcibly bent downward by the load and the buffer space S cannot be maintained. Even when a pair of tongue pieces as in Patent Document 1 are provided, the total load of the plurality of bottles 3 when the bottom surface of the packaging box collides with the floor or the like is supported by only the pair of tongue pieces. Can not.

  The present invention has been made in view of the above problems, and by suppressing the bending of the partition plate and the mounting plate, the holding performance of the bottle against the impact at the time of dropping is improved, and the packaging box drops from the side surface and the bottom surface. It is an object of the present invention to provide a partition that can effectively prevent the bottle from being broken, and a packaging box having the partition.

  In order to achieve the above object, the partition of the present invention is a partition for storing a plurality of bottles in a cubic or rectangular parallelepiped packaging box in a state of being separated from each other. The upper partition plate, the lower partition plate, the mounting plate, and the bottom plate, which are made of paperboard and have an outer shape corresponding to the planar shape of the packaging box, are juxtaposed in order from above at predetermined intervals, and The two opposing sides of the partition plate, the lower partition plate, the mounting plate, and the bottom plate are coupled or bonded to the front and rear plates in the vertical direction corresponding to the front and back surfaces of the packaging box, respectively, and the upper partition The plate and the lower partition plate are provided with a plurality of upper support holes and lower support holes for supporting the body of the bottle, and the buffer plate formed between the plate and the bottom plate is provided with the plate described above. And a vertical reinforcing plate for connecting the bottom plate and the bottom plate to each other.

  According to such a configuration, since the horizontal mounting plate is supported by the vertical reinforcing plate, it is possible to suppress the bending of the mounting plate even when the packaging box drops from the side surface and the bottom surface. Become. Thereby, at least downward position fluctuation of the bottle placed on the placement plate is reduced, and the bottle can be held on the upper partition plate and the lower partition plate against an impact at the time of dropping. As a result, it is possible to effectively prevent breakage due to dropout of the bottle. In addition, if the upper end of the bottle placed on the placement plate is configured to be pressed by, for example, a lid that forms the upper surface of the packaging box, the positional fluctuation of the bottle placed on the placement plate is also reduced. In this case, the bottle can be reliably prevented from falling off unless excessive bending, tearing, peeling, or the like occurs in the upper partition plate and the lower partition plate.

  In particular, the mounting plate connected to the bottom plate by the reinforcing plate has durability that does not easily bend against the impact even when the packaging box falls from the side surface, and can prevent breakage due to dropout of the bottle. It becomes possible. In addition, even if the packaging box falls from the bottom, the total load of multiple bottles can be supported by the mounting plate and the reinforcing plate to maintain the buffer space, so shock absorption when the packaging box falls from the bottom The performance greatly exceeds the conventional partition.

  Preferably, a configuration may be adopted in which a plurality of the reinforcing plates are erected in the buffer space. More preferably, at least one of the reinforcing plates extends substantially parallel to the front plate and the rear plate through substantially the center of the buffer space, or at least one of the reinforcing plates has the buffer space. It is set as the structure extended substantially in parallel with the side surface of the said packaging box through the approximate center.

  As described above, the number, position, and direction of the reinforcing plates in the present invention are not particularly limited. However, as the number of reinforcing plates increases, the number of steps for assembling the partition increases. Therefore, it is preferable that the reinforcing plates be provided in the most effective position and direction and have the minimum number for obtaining the required strength. . For example, in the case of a partition having a configuration in which a plurality of bottles are arranged in two rows along the longitudinal direction of a rectangular parallelepiped packaging box, at least one reinforcing portion is provided along the longitudinal center line of the buffer space. The configuration.

  Preferably, the reinforcing plate and the adhesive margin are cut and raised from the bottom plate, and the adhesive margin is adhered to the back surface of the mounting plate. According to such a configuration, the reinforcing plate can be easily formed simply by partially cutting and raising the bottom plate and bonding it to the mounting plate.

  Preferably, a vertical flap plate corresponding to a side surface of the packaging box is coupled to the other two sides of the upper partition plate facing each other, and in addition to the flap plate of the upper partition plate A vertical flap plate corresponding to the side surface of the packaging box may be coupled to the other two sides of the lower partition plate facing each other.

  According to such a configuration, the two sides of the upper partition plate located on the side surface side of the packaging box, or the two sides of the upper partition plate and the lower partition plate can be reinforced by the vertical flap plate, and the packaging Even when the box falls from the side surface and the bottom surface, it is possible to suppress the vertical bending of the upper partition plate and the lower partition plate. In particular, the upper partition plate and the lower partition plate are provided with durability that does not easily bend even when receiving an impact when the packaging box falls from the side surface, and the upper partition plate and the lower partition plate are prevented from being torn or peeled off. it can. And, even when the packaging box falls from the side and bottom, the bottle is reliably held even when the curbing of the mounting plate by the reinforcing plate and the curbing of the upper partition plate and the lower partition plate by the flap plate are combined. Thus, a partition that can effectively prevent breakage is realized.

  Preferably, the flap plate is extended to the position of the bottom plate. According to such a configuration, when the packaging box falls from the side surface, the flap plate exhibits the above-described reinforcing effect, and when the packaging box falls from the bottom surface, the flap plate reaching the bottom plate is subjected to an impact. The upper partition plate, the lower partition plate, and the mounting plate are prevented from bending.

  Preferably, both the upper support hole and the lower support hole have the same shape slightly larger than the outer shape of the bottle, and the upper support hole is made smaller than the lower support hole.

  With this configuration, it is possible to prevent the bottle from wobbling by making the upper support hole smaller than the lower support hole, and the small upper support hole serves as a guide for positioning the center of the bottle. Insertion into the support hole becomes extremely easy. As a result, both the prevention of bottle dropout and the boxing work efficiency can be improved.

  In order to achieve the above object, the packaging box of the present invention is configured to include the above-described partition of the present invention. According to such a configuration, in the same manner as described above, the curve of the partition plate and the mounting plate is suppressed to improve the holding performance of the bottle against impact, and in any case where the packaging box falls from the side surface and the bottom surface, It becomes possible to prevent damage effectively.

  According to the partition of the present invention and the packaging box provided with this partition, the holding performance of the bottle against the impact at the time of dropping is improved by suppressing the curvature of the partition plate and the mounting plate, Even when falling from the bottom, it is possible to effectively prevent the bottle from being damaged.

  Hereinafter, an embodiment of a packaging box having a partition according to the present invention will be described with reference to FIGS. FIG. 1 is a perspective view showing a packaging box having a partition according to an embodiment of the present invention. FIG. 2A is a cross-sectional view of the inner partition in the short direction, and FIG. 2B is a cross-sectional view taken along the line P-P in FIG. FIG. 3 is a development view of the above-mentioned partition.

<Overall structure>
First, the whole structure of the partition 1 of this embodiment is demonstrated. The substantially rectangular parallelepiped partition 1 shown in FIGS. 1 and 2 is assembled by folding a paperboard punched into the shape shown in FIG. The middle partition 1 is housed in the packaging box 2 and holds the ten bottles 3, 3, 3,.

  In FIG. 1 and FIG. 2 (a), (b), the middle partition 1 is the rectangular upper partition plate 10, the lower partition plate 11, the mounting plate 12, and the bottom plate 13 corresponding to the planar shape of the packaging box 2. It has a configuration in which predetermined intervals are provided in parallel from the top. Two long sides of the upper partition plate 10, the lower partition plate 11, the placement plate 12 and the bottom plate 13 that face each other are respectively connected to the front plate 14 and the rear plate 15 corresponding to the front surface 21 and the rear surface 22 of the packaging box 2. Coupled or bonded.

  The upper partition plate 10 is provided with upper support holes 10a, 10a, 10a... In 2 rows and 5 columns on the basis of the longitudinal direction thereof, and the lower partition plate 11 has a lower concentricity with each upper support hole 10a. Support holes 11a, 11a, 11a... Are drilled. When the bottle 3 is inserted into the pair of upper and lower upper support holes 10a and the lower support hole 11a, the bottom of the bottle 3 is placed on the placement plate 12, and the body portion of the bottle 3 is placed at the upper support hole 10a and It is supported at the edge of the lower support hole 11a.

<< Reinforcement plate >>
2A and 2B, a buffer space S is formed between the placement plate 12 on which the bottle 3 is placed and the bottom plate 13. The partition 1 of this embodiment has a configuration in which a vertical reinforcing plate 16 is erected along the longitudinal center line of the buffer space S. As shown in FIG. 3, the reinforcing plate 16 is obtained by raising a paperboard by inserting a substantially U-shaped cut C at the center of the bottom plate 13. The reinforcing plate 16 connects the mounting plate 12 and the bottom plate 13 to each other by adhering the adhesive margin A4 coupled thereto to the back surface of the mounting plate 12.

  When the bottom plate 13 is a quadrangle, the length of the reinforcing plate 16 can be set to about 2/3 of the side of the bottom plate 13 parallel to the length. For example, when the reinforcing plate 16 is provided in the longitudinal direction of the rectangular bottom plate 13 as in the present embodiment, the length of the reinforcing plate 16 is about 2/3 of the long side of the bottom plate 13. Further, unlike the present embodiment, when the reinforcing plate 16 is provided in the short direction of the rectangular bottom plate 13, the length of the reinforcing plate 16 is about 2/3 of the short side of the bottom plate 13. The total length of the plurality of reinforcing plates 16 provided in the same direction may be about 2/3 of the length of the side of the bottom plate 13 parallel to these.

  Since the horizontal mounting plate 12 is supported by the vertical reinforcing plate 16, even when the packaging box 2 falls from the side surfaces 23 and 24 and the bottom surface, the bending of the mounting plate 12 can be suppressed. It becomes possible. Thereby, the downward position fluctuation of the bottle 3 placed on the placement plate 12 is reduced, and the bottle 3 can be held by the upper partition plate 10 and the lower partition plate 11 against an impact at the time of dropping. it can.

  In particular, the mounting plate 12 connected to the bottom plate 13 by the reinforcing plate 16 has durability that does not easily bend against the impact even when the packaging box 2 falls from the side surface, and is damaged by dropping off the bottle 3. Can be prevented. Even when the packaging box 2 falls from the bottom surface, the total load of the plurality of bottles 3 can be supported by the placement plate 12 and the reinforcing plate 16 so that the buffer space S can be maintained. The shock absorption performance when dropped is also good.

<< Flap board >>
In FIG. 1 and FIG. 2B, longitudinal flap plates 17 and 18 corresponding to both side surfaces 23 and 24 of the packaging box 2 are coupled to the short sides of the upper partition plate 10 facing each other. . These flap plates 17 and 18 reinforce each short side of the upper partition plate 10, and each short side can be easily formed by coupling the vertical flap plates 17 and 18 to the respective short sides in the horizontal direction. Durability not to be bent. The flap plates 17 and 18 can suppress excessive bending of the upper partition plate 10 (see reference numeral 110 in FIG. 5B) when the packaging box 2 falls from the side surface 23 or 24.

  In the present embodiment, the flap plates 17 and 18 have a length that reaches the bottom plate 13 as shown in FIG. Thereby, when the packaging box 2 falls from the bottom surface, the flap plates 17 and 18 reaching the bottom surface plate 13 suppress the bending of the upper partition plate 10, the lower partition plate 11, and the mounting plate 12 against an impact. .

<< About the dimensions of each part >>
As shown in FIG. 2 (a), the inner diameter L1 of the upper support hole 10a and the inner diameter L2 of the lower support hole 11a described above are both the diameters of the barrel portion of the bottle 3 in order to allow the bottle 3 to be inserted. The outer dimensions are slightly larger than L3. Based on this assumption, the present embodiment is configured such that the inner diameter L1 of the upper support hole 10a is smaller than the inner diameter L2 of the lower support hole 11a.

  By making the upper support hole 10a smaller than the lower support hole 11a, the clearance on the upper side of the body portion of the bottle 3 becomes minute, and the wobbling of the bottle 3 is effectively prevented. Further, the small upper support hole 10a serves as a guide for positioning the center of the bottle 3, and the insertion into the large lower support hole 11a becomes extremely easy.

  Furthermore, in order to prevent the bottle 3 from falling off, the height L4 from the bottom plate 13 shown in FIG. 2 to the upper end of the bottle 3 placed on the placement plate 12 is set to the height of the packaging box 2 shown in FIG. Is substantially the same as the length L5 (L5≈L4), or the height difference between L5 and L4 is smaller than the height difference L6 between the lower partition plate 11 and the bottom plate 13 shown in FIG. 2 (L5-L4 <L6). Like that. When L5≈L4, the upper end of the bottle 3 stored in the packaging box 2 is pressed by the lid 25 or the lid flaps 26, 27 of the packaging box 2, and the bottle 3 is prevented from falling off. On the other hand, when L5−L4 <L6, a space narrower than L6 is formed between the upper end of the bottle 3 accommodated in the packaging box 2 and the lid 25 or the lid flaps 26 and 27 of the packaging box 2. However, it is possible to prevent the bottle 3 from falling off.

  As described above, the downward position fluctuation of the bottle 3 is reduced by the mounting plate 12 supported by the reinforcing plate 16. In addition to this, since the position variation of the bottle 3 upward is reduced by the lid 25 or the lid flaps 26 and 27 of the packaging box 2, even when receiving an impact at the time of dropping, the upper partition plate 10 and the lower partition It is possible to reliably prevent the bottle 3 from dropping from the plate 11.

<Configuration and assembly procedure of the unfolded partition>
Next, the configuration of the unfolded state of the partition 1 according to the present embodiment and the assembly procedure will be described with reference to FIGS.

  First, the configuration of the developed state of the partition 1 will be described with reference to FIG. In the same figure, the middle partition 1 has a configuration in which a flat paperboard is punched into a predetermined shape shown in FIG. 3, and a fold line (see a dotted line in the figure) serving as a boundary between each part and a notch C are provided. ing.

  In the figure, the part defined by the folding lines on the four sides is the upper partition plate 10, and the upper support holes 10 a described above are perforated in 2 rows and 5 columns. Hereinafter, the configuration of the developed state of the middle partition 1 will be described with the upper partition plate 10 as the center.

  On the long side on the right side of the upper partition plate 10 in the figure, an allowance A1, a placement plate 12, an allowance A2, a lower divider plate 11, and an allowance A3 are coupled in this order with a bend line as a boundary. . The lower partition plate 11 is provided with the lower support holes 11a described above in 2 rows and 5 columns.

  Further, a front plate 14, a bottom plate 13, and a rear plate 15 are coupled to the long side on the left side of the upper partition plate 10 in this order with a fold line as a boundary. At the center of the bottom plate 13, a reinforcing plate 16 and an adhesive margin A4 are coupled by a substantially U-shaped notch C and two folding lines. On the other hand, on the upper and lower short sides of the upper partition plate 10, a pair of trapezoidal flap plates 17 and 18 are coupled with a folding line as a boundary.

  The assembly procedure of the partition 1 in the unfolded state as described above will be described with reference to FIGS. In these drawings, first, the adhesive margin A1 located on the right side of the upper partition plate 10 is bent 90 ° downward. Next, the mounting plate 12 adjacent to the adhesive margin A1 is bent 90 ° in the horizontal direction. Next, the margin A2 adjacent to the mounting plate 12 is bent 90 ° upward. Next, the lower partition plate 11 adjacent to the margin A2 is bent 90 ° in the horizontal direction. Next, the adhesive margin A3 adjacent to the lower partition plate 11 is bent 90 ° upward and bonded to the inner surface of the adhesive margin A1. Thereby, the upper partition plate 10, the lower partition plate 11, and the mounting plate 12 are arranged in order from the top, and the state in which the long side on each right side is coupled or bonded to the vertical glue margin A1 is assembled.

  Next, the front plate 14 located on the left side of the upper partition plate 10 is bent downward by 90 ° and bonded to the outer surface of the adhesive margin A2. Here, the reinforcing plate 16 and the adhesive margin A4 are raised from the bottom plate 13 adjacent to the front plate 14. That is, the reinforcing plate 16 is bent 90 ° toward the inner surface of the bottom plate 13, and the adhesive margin A 4 is bent 90 ° with respect to the bottom plate 13. Next, the bottom plate 13 is bent 90 ° in the horizontal direction, and the adhesive margin A4 is bonded to the back surface of the mounting plate 12. Thereafter, the rear plate 15 adjacent to the bottom plate 13 is bent upward by 90 ° and adhered to the outer surface of the adhesive margin A1. Thereby, the partition 1 in the state shown in FIGS. 1 and 2 is assembled. Finally, when the flap plates 17 and 18 coupled to the short sides of the upper partition plate 10 are bent 90 ° downward, the assembly of the middle partition 1 is completed.

<Effect>
According to the partition 1 of the present embodiment as described above, the center of the horizontal mounting plate 12 is supported by the vertical reinforcing plate 16, so that the packaging box 2 that houses the partition 1 is a side surface. Even when it falls from 23 and 24 and a bottom face, it becomes possible to suppress the curvature of the mounting board 12. FIG. That is, the vertical reinforcing plate 16 reduces the downward position fluctuation of the bottle 3 placed on the placement plate 12, and resists the impact at the time of dropping the bottle 3 to the upper partition plate 10 and the lower partition. It can be held on the plate 11. As a result, it is possible to effectively prevent breakage due to the dropout of the bottle 3.

  Further, since the upper end of the bottle 3 placed on the placing plate 12 is pressed by the lid 25 that closes the upper surface of the packaging box 2, the positional fluctuation of the bottle 3 placed on the placing plate 12 is also reduced. As long as the upper partition plate 10 and the lower partition plate 11 are not excessively curved, torn or peeled off, the bottle 3 can be reliably prevented from falling off.

  In particular, the mounting plate 12 connected to the bottom plate 13 by the reinforcing plate 16 has durability that does not easily bend against the impact even when the packaging box 2 falls from the side surface, and is damaged by dropping off the bottle 3. Can be prevented. Even when the packaging box 2 falls from the bottom surface, the total load of the plurality of bottles 3 can be supported by the placement plate 12 and the reinforcing plate 16 so that the buffer space S can be maintained. The impact absorption performance when dropped is much higher than the conventional partition.

  Furthermore, the two sides of the upper partition plate 10 positioned on the side surfaces 23 and 24 of the packaging box 2 can be reinforced by the vertical flap plates 17 and 18, and the packaging box 2 falls from the side surfaces 23 and 24 and the bottom surface. Even in this case, it is possible to suppress the vertical bending of the upper partition plate 10 and the lower partition plate 11. In particular, even when the packaging box 2 receives an impact when it falls from the side surfaces 23 and 24, the upper partition plate 10 is provided with durability that does not easily bend, and the upper partition plate 10 can be prevented from being torn or peeled off. Even when the curbing of the mounting plate 12 by the reinforcing plate 16 and the curbing of the upper partition plate 10 by the flap plates 17 and 18 are combined, the packaging box 2 falls from the side surfaces 23 and 24 and the bottom surface. It becomes possible to hold the bottle 3 reliably and prevent breakage effectively.

  In addition, the wobbling of the bottle 3 can be prevented by making the diameter L1 of the upper support hole 10a smaller than the diameter of the lower support hole 11a. At the same time, the small upper support hole 10a serves as a guide for positioning the center of the bottle 3, and the insertion into the large lower support hole 11a becomes extremely easy. As a result, it is possible to improve both the prevention of the dropout of the bottle 3 and the boxing work efficiency.

<Example>
Hereinafter, the Example of the packaging box provided with the partition based on this embodiment is described. This example proves the durability against the falling of the partition and the packaging box of this embodiment.

First, regarding the “side collision of the bottle”, in the test body according to the present embodiment, the bottle from the inner partition is not dropped, and the pressure-sensitive paper indentation (coloring of the portion receiving the pressure) due to the bottle collision is generated. There wasn't. On the other hand, in the test body according to the prior art, the bottle was dropped from the inner partition, and the impression of the pressure sensitive paper due to the collision of the dropped bottle was recognized. Next, regarding the “breakage of the bottle”, no breakage of the bottle was observed in both the present embodiment and the test body according to the prior art. Finally, with respect to the “partition state”, the test piece according to the present embodiment hardly deformed the partition. On the other hand, in the test body of the prior art, as shown in FIG. 5 (b), the inner partition was greatly curved, and it was torn at the end surrounded by the dotted line in the figure, and peeling was recognized.

<< Weight test >>
The mounting plate of each partition (see “Structure of partition” in FIG. 6) used for the side drop test was tested for strength against load. The weight test conditions are as shown in FIG. At the speed of 100 mm / min, the piston-type pressurizing part of “Shimadzu small desktop testing machine EZ Test-100N (T-001)” is the middle part of the short side of the mounting plate of the partition (see FIG. 2B) (See the portion surrounded by the dotted line), and a test was made to determine how much the mounting plate of the partition was subjected to bending.

  The weight test results are shown in the tables and graphs of FIGS. According to the above weight test, the partition mounting plate according to the present embodiment is curved by receiving a load of 0.84 to 0.96 kgf, whereas the partition mounting plate according to the related art is 0. It was found to bend under a load of .39 to 0.44 kgf. As a result, it is recognized that the partition mounting plate according to the present embodiment has a strength with respect to a weight that is about twice that of the prior art.

In addition, the inner partition of this invention and the packaging box provided with this inner partition are not limited to embodiment mentioned above. For example, the number, position, and direction of the reinforcing plates in the partition of the present invention are not particularly limited, and in FIG. 3, a plurality of reinforcing plates 16 may be formed in the longitudinal direction of the bottom plate 13. Alternatively, as shown in FIG. 4, a plurality of reinforcing plates 16 may be formed in the short direction of the bottom plate 13.

  In the above-described embodiment, the flap plates 17 and 18 are coupled to only the short sides of the upper partition plate 10 (see FIG. 3). However, as shown in FIG. The flap plates 17 and 18 may be coupled to the short side, and the lower partition plate 11 may have durability that does not easily curve.

  Furthermore, in this embodiment described above, as shown in FIG. 2A, the diameter L1 of the upper support hole 10a is made smaller than the diameter L2 of the lower support hole 11a, thereby preventing the bottle 3 from falling off and boxing. Although the efficiency has been improved, the diameter L2 of the lower support hole 11a can be made smaller than the diameter L1 of the upper support hole 10a to make it difficult for the bottom of the bottle 3 to fall out of the lower support hole 11a.

  In addition to this, for example, on the inner side of the lid 25 of the packaging box 2 shown in FIG. 1, the reinforcing plate 16 similar to the partition 1, the buffer space S, and the contact plate (on the mounting plate 12) in contact with the upper end of the bottle 3. If the cushioning means comprising the equivalent) is provided, it is possible to prevent the bottle 3 from being damaged when the packaging box 2 is dropped from the lid 25 side (the upper surface of the packaging box 2). In addition, about the fall from the front surface 21 and the back surface 22 side of the packaging box 2, the upper partition plate 10, the lower partition plate 11, the mounting plate 12, and the bottom plate 13 connected to this in the partition 1 become vertical. Therefore, the bottle 3 is not damaged when the packaging box 2 is dropped from the front surface 21 and the rear surface 22 side.

  In addition, in the above-described embodiment, the upper support holes 10a and the lower support holes 11a are formed in 2 rows and 5 columns in the upper partition plate 10 and the lower partition plate 11, but the arrangement of the upper support holes 10a and the lower support holes 11a is as follows. It is not particularly limited. If the upper support hole 10a and the lower support hole 11a correspond to each other in the vertical direction, the number of rows can be increased or decreased as compared with the present embodiment, or the arrangement other than the rows can be changed.
