As a result, as shown in FIG. 2, the container body 48 is a box body having a rectangular cross section that is separated by the front plate 20, the side plates 28, 45, the back plate 34, and the bottom plate 37.
Is molded.

Before the step of assembling this container body 48, by bending the back plate 29 and overlapping it on the back surface of the front plate 20,
The center lines C ₁ and C ₂ of the lengthwise method of the back plate 29 of the front plate 20 are aligned, so that the fold line 23 of the pushing piece 22 and the locking step portion 33 of the locking side 33 are at the same height position. Superimpose on. At this time,
The area excluding the pushing piece 22 and the locking piece 30 is appropriately attached by an adhesive.

Next, the container body 48 in which the back plate 29 is superposed on the back surface of the front plate 20 in this manner is conveyed to the filling operation step (A), and in the filling operation step (A), as shown in FIG. In the container body 48, three cylindrical articles 49 are filled in parallel with each other with their peripheral surfaces adjacent to each other. At this time, in the internal space of the container body 48, since there is no member that hinders the filling of the articles 49 and an integrated space is secured, the filling operation can be performed efficiently. .

When the filling operation step (A) is completed, the container body 48 filled with the three articles is transferred to the partition forming step (B) in which the partition forming device 52 is provided. The partition forming device 52 has an endless belt 50 to which a plurality of pressing members 51 are fixed, the pressing member 51 has a triangular pyramid shape, and has the same interval as the interval between the pushing pieces 22, 22. It is arranged. Therefore, when the container body 48 is transferred in accordance with the traveling speed of the endless belt 50, as shown in FIG. 4, the pushing member 51 pushes the pushing piece 22, and the pushing piece 22 is The connecting portion, which is a discontinuous portion of the temporarily fixed slit, breaks and is pressed inward of the container body 48.

From this, as shown in FIG.

While projecting and displacing inward, the engaging piece 30 on the back plate 29 side is pressed by the projecting displacement of the pushing piece 22. Therefore, the slit 31 is spread by the pushing piece 22, and the slit and the connecting slit are formed.
The locking piece 30 defined by 33a, 33b is separated into the respective separation pieces 30a, 30b by breaking the connecting portion of the temporary fixing, and then bent in the inward direction of the container body 48 from the fold line 32. The contact between the partition forming device 52 and the pressing member 51 is released. By a series of these pushing operations, the pushing piece 22 and the separating pieces 30a, 30b that have been pushed in once try to return to their original state due to the elasticity of the paperboard material that constitutes the container. 25 and the locking step 33 of the separation pieces 30a, 30b are engaged.

As described above, the center lines C ₁ and C of the front plate 20 and the rear plate 29 are
_{Since 2} is in the matched state, when the pushing piece 22 is bent at the fold line 23 located on the center line C ₁ , the bent pushing piece 22 and the center line C ₂ are positioned on the center line C _2. The height positions of the locking step portions 33 of the respective separating pieces 30a and 30b substantially match.

Therefore, when the pushing piece 22 is bent to a substantially horizontal state while expanding the separating pieces 30a and 30b, the pieces are elastically inverted and the locking steps provided on the separating pieces 30a and 30b. The portion 33 and the locking step portion 25 provided on the pushing piece 22 are engaged with each other, so that the pushing piece 22 and each of the separating pieces 30a, 30b maintain a state of protruding displacement in the container body 48. .

Further, as described above, since the tip portion 24 of the pushing piece 22 maintained in the protruding state is provided with the substantially triangular top portion 24, the cylindrical article to which the top portion 24 is adjacent is provided.
By being inserted between 49, the adjacent articles 39 are divided into individual articles, and an effect as a partition is produced.

Moreover, by making the shape of the top portion 24 into a shape corresponding to the dead space generated in the adjacent article 49, the housed article 49 can be restrained with high accuracy, and each of the pieces 22 and 30 functioning as a partition. Since the paperboard material is significantly reduced compared to the partitions 15 and 16 formed by separate members shown in FIGS. 8A and 8B, the material cost can be reduced.

After finishing the partition forming step (B) in this way,
In the next lid closing step, after folding the flaps 35, 46 and the lid body 38, the insertion piece 44 ... the divided pieces 43a, 43b, 43c near the tip end of the sticking cut piece 21.・ A series of work steps are completed by attaching to.

Incidentally, when taking out the article 49 contained in the container body 48, by pulling one of the insertion pieces 44, which is a free end, the tip ends of the divided pieces 43a, 43b, 43c are fixed together with the adhesive cut piece 21. Separated from the face plate 20. If the divided pieces 43a, 43b, 43c are separated from the other divided pieces 43a, 43b, 43c through the cutting line 42, the divided pieces 43a, 43b, 43c are opened and the articles 4 one by one.
9 can be taken out.

Further, when any one of the divided pieces 43a, 43b, 43c is opened to take out the article 49 in this way, the adhesive cut-out piece 21
Will be removed at the same time.
Among them, it is possible to determine, in appearance, which article 49 contained in which part has been taken out, and the insertion pieces 44a, 44b, in the opening formed by removing the adhesive cut piece 21. By inserting 44c, the lid can be closed again after the lid is opened.

In the present embodiment, as shown in FIG. 4, the separating pieces 30a, 30b projecting and displaced in the container body 48 are spread toward the bottom from the top, so that the partition forming step ( In the case of performing the filling step (A) after performing B), the separation pieces 30a, 30 protruding and displaced in the divergent shape at the end
b functions as a guide, and it is possible to smoothly perform the filling operation of the article 49.

FIG. 6 shows another embodiment of the present invention, in which the back plate 29 is extended to one end of the other side plate 49, so that when the container body 48 is formed, The other structure is the same as that of the above-mentioned embodiment except that it is superposed on the back surface side of the front plate 20 and the side glue margin 26 on the short side of the front plate 20 is omitted.

In this embodiment, since the back plate 29 is bent from the side portion of the front plate 20 so as to be overlapped and adhered, before the lid 38 is closed, the front plate 20 and the back plate 29 are It is possible to visually recognize the doubled state. On the other hand, in the above-described first embodiment, since the back plate 29 is bent from the upper part of the front plate 20, the back plate 29 and the front plate 20 are duplicated in appearance. You cannot see it. However, in the first embodiment, since the push-in piece 22 and the locking piece are not aligned because they are connected to each other through the broken line, and the broken line serves as an opening edge, the appearance is excellent.

Further, in each of the above-described embodiments, the push-in piece 22 and the locking piece 30 are provided as a pair, and a type that accommodates three articles 49 is shown. It is possible to increase and decrease freely in the horizontal direction and / or the vertical direction according to the height. Therefore, even if the number of articles to be accommodated is increased or decreased, it is not necessary to make a significant design change to the container for accommodating them, and the number of the pieces 22 and 30 may be increased or decreased in the horizontal or vertical direction. Therefore, it is possible to easily deal with the change in the number and height of the articles to be stored.

Further, in each of the above-described embodiments, the pushing pieces 22, 53 are provided only on the front plate 20, but the rear plate 34
Similarly, if the pushing piece is provided and the back plate 29 on which the locking piece 30 is formed is arranged, each article 49 can be placed on the front plate.
The 20 side and the back plate 34 side can be restrained, and the partitioning performance for the accommodated articles can be further enhanced.

[Effects of the Invention] As described above, the present invention is provided with a pushing piece on the front plate of a box body having a rectangular parallelepiped shape and accommodating a plurality of cylindrical articles in a parallel state with their peripheral surfaces adjacent to each other. When the piece is pressed from the outside, the piece is projected and displaced into a dead space generated between the peripheral surfaces of the article so that the piece functions as a partition. Therefore, before performing the pressing, by performing the filling work of the article into the container, it is possible to smoothly perform the filling work of the plurality of cylindrical articles without being obstructed by the pushing piece, It is possible to improve the work efficiency of.

Further, since the pushing piece protruding and displaced into the container by the pressing is made to engage with the locking piece of the back plate superposed on the back surface of the front plate, the pushing state of the pushing piece into the container is It can be reliably maintained and function properly as a partition plate. Therefore, in consideration of workability at the time of filling the articles, unlike the conventional case in which the partition plate is disposed in the container after the articles are filled, the work after filling the articles is not difficult,
