Description

  The present invention relates to a packaging box for storing ampoules and the like that are easily broken, and more particularly, to a packaging box having a buffer structure capable of preventing damage and dissipation of ampoules due to external impact.

  Conventionally, when storing fragile contents such as ampoules in packaging paper boxes etc., cushioning materials such as foam members and air caps are filled in the gap between the paper box and contents to protect the contents from external impacts. It had been. In addition, the contents are stored in a molded product made of a cushioning material formed in accordance with the shape of the contents, and then stored in a paper box.

  In such a packaging method, it is necessary to prepare a cushioning material separately from the paper box, and the packaging process is complicated. Thus, in a paper box that is assembled by folding a single blank plate, a device is known in which a buffer portion is formed on the entire inner peripheral surface of the paper box (see, for example, Patent Document 1).

Utility Model Registration No. 2562648 (page 3, FIG. 2)

  In the buffer paper box of Patent Document 1, the end portion of the upper lid constituting the top surface of the paper box is extended to form a lid buffer plate that is narrower than the upper lid. And this cover part buffer plate is bent and the front-end | tip is affixed on the back side of an upper cover, The wide part except the outer peripheral part of an upper cover is made into the double structure. And this buffer paper box is provided with the inner side box which makes a side surface and a bottom face double structure. With such a configuration, when the upper lid is closed, the double-structure portion (lid buffer portion) of the upper lid is fitted and closed in the upper opening of the inner box. Thereby, a buffer space is formed on the entire circumferential surface of the storage space.

However, in the configuration of Patent Document 1, the entire top surface of the storage space is a double structure portion. And the cover part buffer plate which comprises the surface inside a box body of a double structure is connected with the upper cover only in the end position close | similar to the side surface of storage space. In other words, the member that holds the distance between the upper lid and the lid buffer plate is provided only at the end position of the storage space. In such a configuration, since a support member is not provided in the central portion of the lid buffering portion, bending easily occurs when pressed, and a sufficient buffering effect on the contents located in the central portion of the storage space There was a problem that could not be obtained.
Moreover, in the structure of patent document 1, since the inner side box and the outer side box were formed with the paper-made board | substrate punched out from the blank sheet of 1 sheet, there existed a problem that an assembly was complicated and manufacturing took time. .

  The present invention has been made in view of the above problems, and its purpose is to effectively prevent damage and dissipation due to external impact of contents such as ampoules stored in the storage space. An object of the present invention is to provide a packaging box having a buffer structure that can provide a sufficient buffering effect even in a part.

Another object of the present invention is to provide a packaging box that can simplify the manufacturing process by forming a box and a buffer structure by bending a single substrate.
Another object of the present invention is to provide a packaging box in which the contents can be easily taken out by enabling opening from the top side.

According to the packaging box of the first aspect, the subject is a substantially rectangular bottom surface and top surface, a side surface connecting the bottom surface and the top surface, and a buffer disposed along the top surface. A packaging box formed so that two or more identical articles can be stored in a horizontal arrangement between the buffer portion and the bottom surface, the buffer portion being a single buffer portion forming piece. The buffer portion forming piece is formed by bending and assembling the support portion, one end of which is connected to a predetermined position of the top surface and forms a support surface that is substantially perpendicular to the top surface, and the other end of the support piece An abutting piece having one end connected to the other side and the other end connected to the side surface and forming a contact surface positioned substantially parallel to the top surface and at a predetermined interval from the top surface, the abutting piece and the support piece is formed by consecutively provided through a line, said abutment surface, in a position which forms the bottom surface a predetermined distance Is constant in contact with all of the two or more identical articles, it said abutment surface is solved by the contact position between each of the two or more identical articles connected to the support surface.

And an upper lid plate 10, an inner lid portion 20 covered with the upper lid plate 10, and a lower box portion 30 that houses an ampoule and the like.
The top surface of the packaging box S is connected to the upper end of the side surface on the long side of the lower box 30 in the state before opening, as shown in FIG. 3A (cross-sectional view along A1-A1 in FIG. 1). The upper lid plate 10 is closed by overlapping and fixing on the middle lid portion 20 connected to the upper end of the other side surface.

The upper lid plate 10 is substantially rectangular, and is provided with an opening piece 11 that slightly protrudes at the center of the long side on the free end side. As shown in FIG. 1, the base end portion of the opening piece 11 is provided. The perforated cuts 12 (12a, 12b) that can be broken are formed obliquely from the center of both short sides. By pulling the opening piece 11 upward to break the perforation, the upper lid plate 10 is cut open as shown in FIGS. 2 and 3B (B1-B1 cross-sectional view in FIG. 2). The substantially trapezoidal extraction port provided in the inner lid part 20 can be exposed to the outside, and the packaging box S can be opened.
When configured to be able to be opened from the top as in the present example, the appearance and quantity of the ampoules stored can be confirmed from the take-out port at the same time as opening. In addition, in the opened state, the possibility of dropping the ampoule is low.

The inner lid portion 20 is configured to cover the top surface of the packaging box S except for a part thereof. 5 and 6 show a state during the assembly of the packaging box S. As shown in the figure, the inner lid portion 20 has a central portion on the long side on the free end side of the top surface. It is assembled so as to have a shape cut out in a substantially trapezoidal shape to the vicinity of the center. This notch serves as a takeout port for taking out an ampoule or the like. Further, as shown in FIG. 5, the inner lid portion 20 is configured to bend the upper side plates 23, 24 provided on both short sides to cover the short side surface of the lower box portion 30 from the outside. Yes.
As will be described later, by assembling the inner lid part 20, a part of the inner lid part 20 has a double structure, and a part of the top surface of the packaging box S has a buffering action.

  The lower box portion 30 is a box with a shallow bottom and a rectangular parallelepiped top surface, and the ampules 2 can be stored in a horizontal row in the inside. As shown in FIG. 7 (a), the ampule 2 is held on a tray-type rondolation 3 in which holding portions matching the outer shape of the ampule are formed at substantially equal intervals so that adjacent ampules do not contact each other. It can be stored in the state that has been done. Such a rotation 3 is widely used as a known buffer material.

(Configuration of box forming substrate)
The packaging box S of this example is formed by folding and assembling a box forming substrate 1 made of a single sheet formed by punching blank paper (blank sheet).
As shown in FIG. 4, the box forming substrate 1 is provided with an upper cover plate 10 on one end side, and on the long side of the upper cover plate 10, a lower plate 32, a bottom plate 31, and a lower plate 33 having substantially the same width. The inner lid plate 21 is connected in series in this order via a broken line.
On the short side of the bottom plate 31, lower plates 34 and 35 that are side surfaces on the short side of the packaging box S are extended. Further, flaps 41 and 42 are respectively extended on the short side of the lower plate 32 forming the long side of the packaging box S, and flaps 43 and 44 are respectively provided on the short side of the lower plate 33. It has been extended. The lower plate and the flap are each connected via a broken line.

On the inner lid plate 21, upper plates 23 and 24 are respectively extended via broken lines on the short side. A pair of cuts 22d and 22e is provided on one long side. By this cutting, a substantially trapezoidal buffer portion forming plate 22 is formed in a part of the inner lid plate 21.
The buffer portion forming plate 22 corresponds to the cut and raised piece of the present invention, and the inner lid plate 21 including the buffer portion forming plate 22 corresponds to the inner lid forming plate of the present invention.

The buffer portion forming plate 22 forms a buffer portion R as shown in FIG. 5 or the like on the back side of the top of the box body, that is, the bottom surface side of the inner lid plate 21, and its base portion is connected via a broken line A. Connected to the inner lid plate 21. The broken line A is provided at a position that is substantially parallel to the long side of the inner lid plate 21 and passes through the approximate center of the inner lid plate 21. Further, the tip of the buffer portion forming plate 22 is provided so as to partially protrude from the inner lid plate 21.
The buffer portion forming plate 22 is provided with a connection support portion 22b on the base side, and a substantially trapezoidal contact portion 22a is connected to the distal end side of the connection support portion 22b via a broken line B. A substantially rectangular fixed portion 22c is connected to the distal end side via a broken line C. The connection support portion 22 b is connected to the inner lid plate 21 via a fold line A that is substantially parallel to the fold line B.
The connection support portion 22b corresponds to the support piece of the present invention, and the contact portion 22a corresponds to the contact piece of the present invention.

  When configured in this way, a substantially trapezoidal notch opening is formed in the inner lid plate 21 by bending the buffer portion forming plate 22 toward the bottom surface at the position of the fold line A. This notch opening is used as a takeout port for taking out the article inside the lower box when opened.

  With the configuration of the box forming substrate 1 as described above, the lower box portion 30 is formed from the lower plate 32, the bottom plate 31, the lower plate 33, the lower plates 34 and 35, the flaps 41 and 42, and the flaps 43 and 44. That is, as shown in FIG. 5, the lower plates 32 to 35 are bent and raised around the bottom plate 31. And adjacent lower side plates can be fixed through the flaps 41-44, respectively. Further, the middle lid portion 20 is formed from the middle lid plate 21, the buffer portion forming plate 22, and the upper side plates 23 and 24. The inner lid portion 20 includes a buffer portion R formed inside the inner lid plate 21 by the buffer portion forming plate 22 as described below.

(Composition of buffer part and effect)
Next, with reference to FIG. 3 and FIG. 6, a buffer portion R that is a characteristic configuration of the packaging box S of the present example formed by assembling the box forming substrate 1 as described above will be described. The buffer portion R is a double structure portion provided on the back side of the top surface of the packaging box S by the inner lid plate 21 and the buffer portion forming plate 22 having the shape described above, and forms a buffer space R1 on the back side of the top surface. It is.

In order to form the buffer portion R including the buffer space R1, first, the fold lines A and B of the buffer portion forming plate 22 and the fold line D (see FIG. 4) of the inner lid plate 21 are formed on the packaging box as described above. While being folded to the inner side, that is, the side that is the back side of the top surface when assembled (direction of arrow a shown in FIG. 6), the fold line C is bent to the outside of the packaging box (direction of arrow b shown in FIG. 6). Then, the fixing portion 22 c is fixed to the lower plate 33. At this time, the polygonal lines A to D are each bent at a substantially right angle.
The box forming substrate 1 of this example is dimensioned so that the interval between the polygonal line A and the polygonal line D is substantially equal to the interval between the polygonal line C and the polygonal line B. The fixing portion 22c is fixed at a position where the fold line D and the fold line C are separated by a width dimension (dimension X shown in FIGS. 3B and 6) of the connection support portion 22b.

  When the buffer portion R is assembled in this way, the abutting portion 22a is moved from the inner lid plate 21 to the box as shown in the cross-sectional configuration of the packaging box S of this example shown in FIGS. The inner lid plate 21 is positioned substantially parallel to the inner lid plate 21 on the inner side (the back surface side), and has a buffer space R <b> 1 between the inner lid plate 21. One end of the contact portion 22a is supported by the inner lid plate 21 via the connection support portion 22b at the positions of the polygonal lines A and B (that is, near the center of the short side length of the top surface). The other end is supported by a lower plate 33 that forms the side surface of the packaging box S.

In addition, by bending the buffer portion forming plate 22, the inner lid plate 21 is formed with a notch portion formed in a substantially trapezoidal shape up to the vicinity of the center of the top surface, leaving both ends of the long side on the free end side. In this example, this notch is used as an outlet for taking out an ampoule or the like.
Since the box forming substrate 1 is configured to use the portion notched in the inner lid plate 21 so as to form an outlet for ampoules or the like in order to form the buffer portion R. A separate substrate is not required to form the portion R. Therefore, the manufacturing process is simplified, and it is possible to manufacture at a low cost, which is preferable.

  As described above, in this example, the buffer portion R is raised three-dimensionally in the center of the top surface by a simple manufacturing process in which the sheet-forming box-forming substrate 1 is formed with cuts and bent and assembled. Can do. That is, by such a simple manufacturing process, the double structure including the two surfaces of the inner lid plate 21 and the contact portion 22a, the buffer space R1 between these two surfaces, and the side surface portion of the buffer space R1 are enclosed. A buffer portion R having a connection support portion 22b and a lower plate 33 that support the contact portion 22a so as to maintain a distance between the two surfaces is formed. As described below, the buffer portion R of the simple configuration and the manufacturing process exhibits an advantageous buffering effect as compared with the buffer structure of the conventional example, so that the ampoule and the like housed therein can be stably Can be held in.

  The applicant of the present application, as in this example, has a double-structured buffer portion that supports an object that is in contact with the contact surface by spanning the contact surface between the support portion and the support portion. It was noted that the part of the surface away from the support part is unstable in structure and more easily bent by impact than the part supported by the support part, and a sufficient buffering effect cannot be obtained. For example, as shown in FIG. 14 (a), in a buffer paper box in which the lid portion is entirely double-structured and the support portion is provided only on the outer periphery of the double-structure portion, similar to the above-described conventional buffer structure. In the central part of the box, the article is supported at a position that is easy to bend away from the support part. Therefore, at the time of impact, as shown in FIG. 14B, there is a possibility that problems such as breakage may occur due to bending of the contact portion. Moreover, as shown in FIG.14 (c), there exists a possibility of rattling in a paper box and being damaged.

  On the other hand, the applicant of the present invention is able to obtain a sufficient cushioning effect in a packaging box for storing a plurality of fragile contents such as ampoules side by side, and can be manufactured easily and at a low cost. As a result of various studies on the configuration, as shown in FIGS. 3A and 3B, the double structure portion and the article housed in the packaging box are brought into contact with each other so that the article is supported at the position where the article is supported. The idea was to provide a support to support the heavy structure. By setting the position in this manner, the article is abutted and supported by a portion that is difficult to bend due to the impact, so that the impact is buffered and the article is supported stably without rattling, that is, sufficient cushioning. I came up with the idea that it would be effective.

  Based on such considerations, the buffer portion R of the present example passes through the connection support portion 22b that supports one end of the contact portion 22a through the vicinity of the center of the short side length of the top surface and is parallel to the long side direction. Arranged. That is, as shown in FIG. 7B, the position of the connection support portion 22b crosses the vicinity of the center in the length direction of each of the ampules 2 that are stored in a line in the inner space of the packaging box S. The position was set. Further, the length of the connection support portion 22b is set so that both ends N and M reach the centers of the ampoules 2a and 2b located at both ends. In FIG.7 (b), the site | part in which the buffer part R is provided, ie, the site | part made into the double structure, is shown with the oblique line.

With such a configuration, the buffer portion R of this example has one end of the contact portion 22a (see FIG. 3) in contact with the vicinity of the center of all the ampoules 2 that are housed, and is connected at this contact position. It is supported by the support portion 22b. Thereby, even if an impact is applied from the outside, the impact is buffered by the elastic force of the connection support portion 22b made of paper material in the vicinity of the center of the ampoule 2, and the contact portion 22a does not bend. In this way, if the buffer portion is provided at the center of the top surface where the ampoule 2 and the contact portion 22a are in contact, the ampoule 2 can be supported near the center without rattling by the contact portion 22a. it can.
Thus, with the configuration of this example, it is possible to reliably obtain a buffering effect and reliably prevent the article from being damaged. In addition, since a sufficient buffering effect is exhibited even for heavy contents such as ampules of liquid injection preparations, damage and the like are reliably prevented.

  In the buffer portion R of this example, the other end portion of the contact portion 22a is supported by the lower plate 33 (see FIG. 3), and is also supported by the connection support portion 22b in the vicinity of this end portion. Like the end portion, the impact is buffered and the contact portion 22a does not bend. In this example, all the ampoules are arranged so that the lower plate 33 side is on the ampoule bottom side, and the ampoule 2 has substantially the same diameter at the center portion and the bottom portion. All the ampoules 2 are brought into contact with each other at the end on the lower plate 33 side. Therefore, the bottoms of all the ampoules 2 are supported without rattling by the contact portion 22a. In this way, if all ampoules are supported without rattling at the center and the bottom, the shock-absorbing effect is greatly improved compared to the conventional double-structure shock-absorbing structure. Etc. are reliably prevented.

(Modification Example 1: Modification of position and shape of buffer part)
The position and shape of the buffer portion R of the present invention can be variously modified in addition to the above embodiments. FIGS. 8B to 8G show the position and shape of the buffer portion R provided in the packaging box of the first modification. Moreover, Fig.8 (a) is the position and shape of the buffer part R in the packaging box S of the said Example. In FIG. 8, similarly to FIG. 7B, a portion where the buffer portion R is provided, that is, a portion having a double structure is indicated by hatching.
The packaging box S1 shown in FIG. 8 (b) has a rectangular shape instead of the buffer portion forming plate 22 having a trapezoidal shape. In this example, the connection support portion 122b has a width that reaches a little outside the center of the ampules 2a and 2b accommodated at both ends of the box, and the ampules including the ampules at both ends are more reliably contacted and supported. ing. Further, in the packaging box S <b> 2 shown in FIG. 8C, both ends of the connection support portion 222 b have a length that reaches both side surfaces on the short side of the lower box portion 30. Moreover, the connection support part 322b of the packaging box S3 of the modification shown in FIG. 8D is a combination of the modifications shown in FIGS. 8B and 8C.

In the packaging box S4 shown in FIG. 8 (e), the connection support portion 422b is provided at a position slightly closer to the neck side of the ampoule 2 rather than the center of the short side length of the top surface. Further, in the packaging box S5 shown in FIG. 8 (f), the connection support portion 522b is provided obliquely with respect to each side of the top surface. And as for the packaging box S6 shown in FIG.8 (g), the center part of the connection support part 622b is provided in the approximate center of the short side length of a top | upper surface, and a level | step difference is formed between a center part and both ends, Both end portions are provided at positions slightly close to the bottom side of the ampoule 2.
In each of these modified examples, a support portion for supporting the double structure is provided at a position where the double structure portion and the article stored in the packaging box are brought into contact with each other to support the article. ing. Accordingly, the article is abutted and supported by a portion that is difficult to be bent by an impact, the impact is buffered, and the article is stably supported without rattling, and a sufficient buffering effect is obtained.

(Modification 2: Modification of the position of the opening surface)
In each of the above embodiments, the packaging box is formed on the premise that the packaging is opened from the top surface, but the present invention can also be applied to the packaging box opened from the side. FIGS. 9 and 10 are explanatory diagrams showing the configurations of the packaging boxes S7 and S8 of the second modification.
As shown in FIG. 9A, the packaging box S7 of this example is formed by bending and assembling a blank plate that is continuously provided via a folding line in the order of a top plate 710, a side plate 733, a bottom plate 731, and a side plate 732. ing. Further, a contact portion 722a is provided substantially parallel to the top plate 710, and a buffer space R1 is formed inside the box of the top plate 710. One end of the contact portion 722a is connected to the side plate 733, and the other end is connected to the connection support portion 722b. The connection support portion 722 b is provided so as to be substantially perpendicular to the top surface plate 710 at a substantially central portion of the top surface plate 710. The other end of the connection support portion 722 b is connected to the tip of a connection plate 736 that is connected to the tip of the side plate 732 and extends to the approximate center of the top plate 710.

Moreover, the packaging box S8 of this example includes a top plate 810, a side plate 833, a bottom plate 831, and a side plate 832 as shown in FIG. This packaging box S8 is for packaging in that the contact portion 822a extends from the upper end of the side plate 833 instead of the side plate 832 and that the top plate 810 is provided with a flap 833a that covers the side plate 833. Although different from the box S7, the buffer space R1 having a double structure is formed by the contact portion 822a and the connection support portion 822b as in the above embodiments.
And in the packaging boxes S7 and S8 of this example, as shown in FIG.9 (b) and FIG.10 (b), the opening part provided in the side surface is opened, and the ampoule 2 is taken out from the side surface. As described above, the buffer structure having the support surface and the contact surface of the present invention can be applied to a packaging box that is not a top-opening type as in this example. And like each said Example, sufficient buffering effect with respect to the impact from the outside is acquired, and damage and dissipation of an internal article can be prevented effectively.

(Modification 3: Modification of the number of stacked articles)
In each of the above embodiments, the ampules 2 are accommodated in a horizontal row inside, but the present invention can be applied to a packaging box in which the ampules 2 are stacked and accommodated. FIG. 11 is an explanatory diagram showing the configuration of the packaging box S9 of the third modification.
As shown in FIG. 11A, the packaging box S9 of this example includes an upper lid plate 910, a side plate 932, a bottom plate 931, a side plate 933, an inner lid plate 921, a connection support portion 922b, and an abutting portion 922a in this order. It is formed by bending and assembling a blank plate provided continuously through a broken line. That is, this packaging box S9 is a top surface opening type like the first embodiment and the modified example 1, and the buffer space R1 is provided in the inner lid portion. In addition, FIG.11 (b) is C1-C1 sectional drawing of Fig.11 (a).

  In this example, ampules 2 are stacked and accommodated in four layers inside the box via a londlation 3. The number of layers may be two or three, or five or more. In this example, in order to further improve the buffering effect, a double structure portion is also provided on the bottom surface side. That is, the contact portion 931a is provided on the box inner side of the bottom plate 931. In this example, the double structure portion on the bottom surface side is formed so as to have a double structure over the entire bottom surface. However, as with the top surface side, a support portion (supporting portion 931a that supports the contact portion 931a at the substantially central portion of the bottom surface) A configuration similar to that of the connection support portion 922b may be provided. Thus, the buffering effect can be improved by providing the buffer structure also on the bottom surface side, and the stacked ampules can be stably indicated.

表１に、アンプル破損数及びアンプル破損が認められた試験体（包装用箱）の数を示す。従来品の包装用箱に相当する試験体（Ｃ−１０）では、破損が１００管中５管（１０箱中５箱）発生しているのに対し、本発明相当品（Ｂ−１０）では、１０ｍＬアンプルの破損は全く発生しなかった。このように、本発明相当品（Ｂ−１０）の方が、従来品（Ｃ−１０）に比べて内容物の破損が少なく、落下時の耐衝撃性が高いという結果が得られた。
なお、アンプルの破損部位は、ほとんどがアンプルの首の部分（調剤時に折る部分）であった。 (3) Results

Table 1 shows the number of ampoules damaged and the number of specimens (packaging boxes) in which ampoule damage was observed. In the specimen (C-10) corresponding to the conventional packaging box, breakage occurred in 5 out of 100 tubes (5 out of 10), whereas in the product equivalent to the present invention (B-10). No damage to the 10 mL ampoule occurred. Thus, the results of the present invention equivalent product (B-10) were less damaged than the conventional product (C-10), and the impact resistance when dropped was high.
In addition, the damaged part of the ampoule was mostly the neck part of the ampoule (the part that folds during dispensing).

Moreover, according to the consideration based on the said experimental result, the packaging box of this invention has the following effects.
Even in the configuration of the conventional product (C-10), it is expected that the impact is less likely to be transmitted to the ampoule by increasing the gap dimension of the buffer portion R (dimension Z2 in FIG. 12D). That is, if the gap size is large, the deflection generated on the outer surface of the buffer portion due to an external impact is less likely to be transmitted to the inner surface of the buffer portion than when the gap size is small. Therefore, it is considered that the shock is hardly transmitted and the buffering effect is enhanced.
On the other hand, when the gap dimension is increased, the outer dimension in the thickness direction of the packaging box is increased, and the volume of the packaging box is increased. Therefore, a large space is required during storage and transportation, and costs during storage and transportation increase. Further, since the area of the box forming substrate is increased, there is a problem that the material cost is increased.
Thus, the packaging box provided with the buffer portion R of the present invention is provided with the buffer portion R not on the entire top surface but on a part of the top surface, so that the gap size of the buffer portion R is kept small, i.e., the packaging. While suppressing the occupied volume of the box, there is an effect that an effective buffering effect can be obtained.
