Description

  The present invention relates to a packaging case for packaging products and the like, which is assembled from a single plate such as corrugated paper.

  Conventionally, a packaging case formed from a single sheet punched from a base paper has been as shown in FIG. That is, in the development view of the packaging case in FIG. 17A, side plates 101a, 101b, and 101c are continuously provided on the four sides of the bottom plate 100. In the side plate connected to the bottom plate 100, for example, in FIG. 17, the joining pieces 102a are connected to both ends of the side plate 101a, and the joining pieces 102c are connected to both ends of the side plate 101c. And the accommodation space is formed by adhering the outer surface of 102c to the inner surface of the side plate 101b.

  The bottom plate 100 is formed in the same size as the bottom plate 100. The side plate 101 is sandwiched between any one of the four side plates 101 and the bottom plate 100, and the cover plate 103 is interposed via the folding line 103a. It is connected continuously. Furthermore, an insertion piece 104 is connected to the tip of the cover plate 103 via a fold line 103b. Then, in the perspective view after assembly of the packaging case shown in FIG. 17 (b), the folding plate 103a and 103b are folded so that the cover plate 103 is put on the formed box, and the insertion piece 104 is attached to the side plate 101a. It is inserted along the inner side and fixed to the box body on which the cover plate 103 is formed.

In the conventional packaging case configured as described above, a joining piece 102 for fixing the side plate 101 in a state of being bent perpendicularly to the bottom plate 100 at the time of assembling is necessary. When fixing to the side plate 101, it is necessary to use an adhesive or the like, so that the assembly work is complicated.

  Therefore, Patent Document 1 proposes a packaging case as shown in FIG. In FIG. 18, (a) shows an unfolded state, (b) shows a state during assembly, and (c) shows a state after assembly. A side plate 201 is connected to both long sides of the bottom plate 200, a cover plate 202 is connected to the side of one side plate 201, and an insertion piece 203 is connected to the side of the cover plate 202. It is connected continuously. Further, end plates 204 are continuously provided on both short sides of the bottom plate 200, and contact pieces 205 are continuously provided on an end portion of the end plate 204 facing the bottom plate 200. A substantially V-shaped fold line is provided between the side plate 201 and the end plate 204, with four corners of the bottom plate 200 as intersections, and a connecting piece 206 is formed by the fold line. .

  In assembling the packaging case configured in this way, first, the side plates 201 and the end plates 204 on both sides with respect to the bottom plate 200 are raised vertically upward, and at the same time, the connecting piece 206 is perpendicular to the end plate 204. The connecting piece 206 is bent along the side plate 201 and the contact piece 205 is bent horizontally. Next, the insertion piece 203 is bent perpendicularly to the lid plate 202 and is bent so that the lid plate 202 is horizontal, the insertion piece 203 is inserted along the inner surface of the side plate 201, and the lid plate 202 is fixed. . When the packaging case is assembled, a space S is formed between the connecting pieces 206 facing each other at both ends, and the space S and the connecting piece 206 have a cushioning action due to elasticity in the surface direction.

  However, in the packaging case described in Patent Document 1, since it is not necessary to use an adhesive or the like when assembling the packaging case, the assembling work of the packaging case is easy, and the work efficiency can be improved. Since the assembled packaging case has only one space for storing products and the like, there is a problem that a partition plate or the like must be separately provided to store a plurality of products and the like.

  Therefore, Patent Document 2 proposes a packaging case as shown in FIG. In FIG. 19, (a) shows an unfolded state, (b) shows a state during assembly, and (c) shows a state after assembly. As shown in FIG. 19 (a), side plates 301 are connected to both long sides of the bottom plate 300, and a cover plate 302 is connected to the outer sides of these side plates 301. On the outside of the cover plate 302, an intermediate partition piece 303 is connected.

  Further, end plates 304 are continuously provided on both short sides of the bottom plate 300, and a substantially V-shaped fold line between the side plate 301 and the end plate 304 with four corners of the bottom plate 300 as intersections. The trapezoidal auxiliary assisting piece 305 is formed by this folding line. Further, the above-described middle partition piece 303 and end plate 304 are provided with notches for fitting 303a and 304a, respectively.

When assembling the packaging case configured as described above, when the side plates 301 on both sides are bent upward with respect to the bottom plate 300 as shown in FIG. The sandwiched end plate 304 naturally stands up. In this state, after placing a product or the like accommodated in the packaging case on the bottom plate 300, the lid plate 302 and the intermediate partitioning piece 303 connected to the side plate 301 are bent inward, and each fitting notch By fitting 303a and 304a, a packaging case having a partition as shown in FIG. 19C can be assembled easily and quickly.

When the fold line between the side partition plate 16 and the first support plate 17 is bent in the direction of arrow E in FIG. 7, as shown in FIG. 12A, the holding opening 21 and the bent holding piece 22 come to face each other. After this state, the bent holding piece 22 is bent into the holding opening 21.

  At this time, as described above, the length of the bending holding piece 22 in the Y-axis direction is longer than the portion of the insertion portion 21a formed shortest in the Y-axis direction at any position. Since the holding piece 22 comes into contact with the protruding portion 21c, as shown in FIG. 12B, the bent holding piece 22 and the protruding portion 21c are temporarily elastically deformed, but the bent holding piece 22 is completely fixed. When fitted to 21b, the protruding portion 21c returns to its original position due to its own elasticity, so that the protruding portion 21c protrudes onto the bent holding piece 22 as shown in FIG. Thus, the bent holding piece 22 is prevented from returning to the original position.

  And as shown in FIG.12 (c), when the bending holding piece 22 is fitted by the fixing | fixed part 21b, as mentioned above, the length of the Y axis direction of the bending holding piece 22 will approach a front-end | tip. Accordingly, the length in the Y-axis direction is gradually increased, and the fold line between the side partition plate 16 and the first support plate 17 is bent in the direction opposite to the arrow E in FIG. Then, since both ends in the Y-axis direction of the bending holding piece 22 interfere with both ends in the Y-axis direction of the fixed portion 21b, the folding line between the side partition plate 16 and the first support plate 17 is bent. Will be held.

  After the folding line between the side partition plate 16 and the first support plate 17 is bent, the side plates 3 and 4 and the both end plates 5 on both sides are lifted upward with respect to the bottom plate 2 as shown in FIG. Stand up vertically. At the same time, the connecting pieces 6 and 7 are bent to the outside of the end plate 5, the connecting piece 6 is placed along the inner surface of the side plate 3, and the connecting piece 7 is placed along the inner surface of the side plate 4. Next, the side partition plate 16 and the first support plate 17 are folded as shown by an arrow F in FIG. At this time, since the folding of the fold line between the side partition plate 16 and the first support plate 17 is held by the bending holding piece 22 as described above, the side partition plate 16 or the like is folded. Work can be done easily.

  Further, at this time, by fitting the fitting notch 5a formed on the end plate 5 and the fitting notch 16a formed on the side partition plate 16, the side partition plate 16 becomes the end as shown in FIG. The box is maintained by being fixed to the plate 5. Then, as shown in FIG. 9, the inside of the box formed as described above is partitioned laterally by the side partition plate 16 and surrounded by the side plate 3, the end plate 5, and the side partition plate 16. A first storage space S1 and a second storage space S2 surrounded by the side plate 4, the end plate 5 and the side partition plate 16 are formed.

  Furthermore, when the side partition plate 16 and the first support plate 17 are folded, as shown in FIG. 13, the support provided at both ends of the side partition plate 16 and the first support plate 17 in the Y-axis direction. The pieces 16b and 17a are bent inward of the box by contacting the both end plates 5, and as shown in FIG. 9, when the box is formed, the bottom plate in the first storage space S1 is automatically formed. 2 are arranged in a standing state at both ends in the Y-axis direction.

  And after forming a box, the base plate 18 is bent in the direction shown by the arrow G in FIG. At this time, the folding line between the base plate 18 and the second support plate 19 is bent so that the second support plate 19 stands vertically downward with respect to the base plate 18, and is provided on the second support plate 19. The support plate fixing piece 19 a thus formed is inserted into the slit 2 a formed in the bottom plate 2. As a result, the base plate 18 is supported by the first support plate 17 and the second support plate 19 to form a bottom buffer portion.

  In addition, since the lower end part of the first support plate 17 is continuous with the side partition plate 16, the first support plate 17 is fixed by the side partition plate 16. Since the folding of the folding line is held by the bending holding piece 22, the first support plate 17 is prevented from being tilted with respect to the bottom plate 2. Further, since the lower end portion of the second support plate 19 is fixed by the engagement between the support plate fixing piece 19a and the slit 2a, the second support plate 19 is prevented from being tilted with respect to the bottom plate 2. Yes.

  Here, the both ends of the base plate 18 in the X-axis direction are supported by the first support plate 17 and the second support plate 19, and further, both ends in the Y-axis direction are supported by the support pieces 16 b and 17 a. Therefore, the pedestal plate 18 is less likely to be crushed at the time of a drop impact or the like than when the pedestal plate 18 is supported only by the first support plate 17 and the second support plate 19, and the stored product etc. A moderate buffering property can be maintained.

  As shown in FIGS. 14 and 15, when the base plate 18 is bent, the positioning pieces 24a and 24b connected to the base plate 18 pass through the insertion openings 23a and 23b, respectively. Then, it automatically protrudes into the second storage space S2. Thereby, even if the length in the longitudinal direction of a product or the like stored in the second storage space S2 is shorter than the first storage space S1, the positioning pieces 24a and 24b allow the product to be stored in the second storage space S2. Since shakiness of stored products and the like is suppressed, there is no need to separately provide a fixing member.

  Then, as shown in FIG. 16, a storage item 25 such as a product is stored in the second storage space S <b> 2, and when the storage item 25 has a protruding portion 25 a, the flaps 20 a and 20 b are opened. 14 is bent into contact with both ends in the Y-axis direction of the protruding portion 25a of the stored item 25, and rattling of the stored item 25 can be more effectively suppressed.

  Further, for example, as shown in FIG. 16, when the protruding portion 25 a is not located at the center in the Y-axis direction of the stored item 25, that is, when the stored item 25 is asymmetric in the Y-axis direction, the stored item 25 is When rotated 180 °, the protruding portion 25a interferes with the flap 20a as shown by the dotted line, and the flap 20a cannot be bent. Therefore, it is possible to limit the storage direction of the storage item 25 by adjusting the positions of the positioning piece 24 and the flap 20.

  After the product or the like is stored in the first storage space S1 and the second storage space S2, the cover plate 8 is bent in the direction shown by the arrow H as shown in FIG. The opening case 14 is inserted along the inner surface of the side plate 4, and the lid plate fixing piece 15 is inserted into the slit 9 a provided in the insertion piece 9 inserted into the opening portion 14 from the outer surface side, thereby packaging case. Is completed. Here, as shown in FIG. 11, both end portions of the side plates 3, 4, the connecting pieces 6, 7, the lid plate 8, and the side partition plate 16 protrude at both end portions of the assembled packaging case. These projecting parts have a buffering action against the impact in the end face direction.

  The present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention. For example, in the first embodiment, the side partition plate 11 and the vertical partition Although all the spaces partitioned by the partition plate 12 are used as product storage spaces, these can also be used as buffer spaces without storing products or the like. Further, the side partition plate 11 and the vertical partition plate 12 can be freely changed in position, size, and number, and can be appropriately changed according to the size and number of products to be accommodated. In the second embodiment, the number and shape of the positioning pieces 24 and the insertion openings 23 can be changed as appropriate.

  INDUSTRIAL APPLICABILITY The present invention can provide a packaging case with improved assembling workability and packing workability when used for a packaging case assembled from a single sheet of cardboard paper, etc. Since the positioning piece and the buffer portion having the function of the buffer material are integrally formed on the main body, the number of components is reduced, which contributes to the cost reduction.
