JP5207044B2 - Fixing structure between outer case and partition - Google Patents

Description

  The present invention relates to a fixing structure between an outer case and a partition that is compatible with an automatic packaging line.

  There are many so-called assembly boxes in which the inner partition is fitted in the outer case, which are on the market and can be held in such a manner that, for example, glass vials, ampoules, bottles, etc. are inserted into each space portion of the inner partition. .

  Here, the relationship between the outer case and the inner partition is generally simply inserted without fixing the inner partition with respect to the outer case, and many adopt this form.

However, the above-described configuration has the following problems.
(1) On the automatic packaging line, the process of fitting the inner partition into the outer case and fixing it cannot be realized easily.
(2) Since the partition is detached from the outer case or protrudes from the outer case during packing work during delivery or vibration during transportation, customer complaints are likely to occur.
(3) Since distortion and misalignment in the automatic packaging line are likely to exist, the automatic packaging line is stopped and it is difficult to smoothly assemble the box.

Therefore, this type of industry is awaiting the development of a fixing structure between the outer case and the inner partition that does not move up and down and left and right with respect to the outer case on the automatic packaging line.

Further, the convex surface 70 can be fitted substantially in alignment with the concave portion 30, and in this fitted state, the insertion piece 71 is structured to be in contact with the root portion 31 a of the receiving piece 31.
(Regarding steps 1, 2, and 3 for fixing the partition 5 to the outer case 1)
"First step"
As shown in FIGS. 7A and 8A, the partition 5 is inserted from the bottom open portion of the outer case 1.
"Second step"
When the intermediate partition 5 is further pushed in from the state shown in FIGS. 7A and 8A, the insertion piece 71 is inserted into the receiving piece 31 as shown in FIGS. 7B and 8B. It will be inserted.
"Third step"

The tip of 71 comes into contact, and at the same time, the convex portion 70 fits into the concave portion 30.

As a result, the middle partition 5 becomes immovable with respect to the outer case 1 by fitting the convex portion 70 into the concave portion 30.
(About the process of locking and fixing the inner partition 5 in the outer case 1 in the automatic packaging line)
(1) The bottom surface of the outer case 1 is opened in such a manner that the bottom surface of the outer case 1 is transverse to the conveying direction of the packaging line, and the automatic packaging device for the partition 5 is inserted from the bottom surface opening portion. At this time, as a matter of course, the concave portion 30 and the receiving piece 31 and the convex portion 70 and the insertion piece 71 are made to coincide with each other on the upper side or the lower side. In the embodiment, it is assumed to be on the upper side.
(2) When the middle partition 5 is gradually inserted from the bottom side of the outer case 1, the convex portion 70 and the insertion piece 71 enter the outer case 1 as described above.
(3) When the insertion amount is further increased from the state of (2), the insertion piece 71 comes into contact with the root portion 31a of the receiving piece 31, and at the same time, both the convex portion 70 and the concave portion 30 The lowermost part (straight line part) and the sides in the vicinity thereof are surely brought into a locked state. In this state, the inner partition 5 is not moved in any direction with respect to the outer case 1, and neither moves when the outer case 1 is opened or closed.
(About excellent effects of this embodiment)
(1) From the above contents, it is clear that the process of fitting and fixing the inner partition in the outer case can be easily performed on the automatic packaging line.
(2) Even if there is vibration during packing or delivery during delivery, the insertion piece 71 comes into contact with the base portion 31a of the receiving piece 31, and at the same time, the lowest portions of both the convex portion 70 and the concave portion 30. (Straight part) and the side of the neighborhood etc. are surely locked, so the inner partition does not come off from the outer case or protrude from the outer case. It becomes difficult to come out.
(3) For the same reason as in (2) above, since distortion and misalignment in the automatic packaging line are unlikely to occur, the automatic packaging line is unlikely to stop and smooth box assembly work can be performed.
(Other)
The concave portion 30, the receiving piece 31 and the base portion 32 formed in the outer case 1, the protruding piece 51 formed in the inner partition 5, the partition piece 52, the crosspiece 53, the cutting line, and the like are not particularly limited to the above embodiment. When the intermediate partition 5 is inserted into the outer case 1, the insertion piece 71 comes into contact with the root portion 31a of the receiving piece 31, as shown in FIGS. 7 (c) and 8 (c). It is only necessary to have a structure in which both the lowermost portions of the convex portion 70 and the concave portion 30 and the sides in the vicinity thereof are in a locked state.

  It is preferable that the concave portion 30, the receiving piece 31, the root portion 32, and the like of the outer case 1 adopt the following configuration. A notch 31b is made in the central portion of the base portion 31a of the receiving piece 31, and two ruled lines 32 are provided below the recess 30. Further, the outer side plate 13 and the inner front plate 14 between the ruled lines 32 and 32 are provided. Are preferably bonded with glue (the bonding portion is indicated by reference numeral 36). With this configuration, the partition 5 can be more smoothly fixed to the outer case 1.

  Further, when a glass vial, an ampoule, a bottle, or the like closely packed in the space is inserted into the space partitioned by the middle partition 5, the receiving piece 31 is positioned so as to be pressed by the glass vial container. For example, the effect of (2) in the column (about the excellent effect of this embodiment) is further improved.

  Further, the protruding piece 51 protruding from the upper end of the outer frame portion 50 of the inner partition 5 is bent outward to form a convex portion 70 corresponding to the concave portion 30 and an insertion piece 71 corresponding to the receiving piece 31. It is possible to adopt other methods.

  And the outer case 2 and the partition 5 inserted in this are the top view rectangles, and the recessed part 30, the convex part 70, the receiving piece 31, and the insertion piece 71 are formed in the top view center of the side corresponding to a long side. It is preferable to have it. That is, with this configuration, the backlash of the partition 5 with respect to the outer case 1 is reduced.
