    Various protective members are attached to the pre-use cartridge in consideration of safety during transportation. For example, in the case of a developing cartridge, a blocking member is attached to the developer discharge port and the exposed portion of the developing roller in order to prevent the developer from flowing out. For this reason, when exchanging the cartridge, it is necessary to perform setup work such as work for removing the blocking member, and work for attaching an adapter for coupling with the machine body after removal.

    Since these operations are performed with the cartridge lying on the floor surface, the developer is often spilled and the floor surface may be soiled. There is also a problem that dust on the floor surface adheres to the cartridge. For this reason, it is desirable to set up a work mat and then perform setup work on it, but it is necessary to consider the loss of work time, securing an appropriate location, etc., and maintenance personnel always carry the work mat. There are inconveniences that must be made.

    In order to eliminate the inconvenience, it is conceivable to flatten the packaging box after taking out the pre-use cartridge and place it on the floor.

    However, it is necessary to squeeze the packing box as shown in Patent Document 1 flatly or to develop it into a single sheet, and it is also necessary to temporarily place the cartridge on the floor surface during the work. There is a problem of taking a large work place.

    Accordingly, an object of the present invention is to devise the shape of the cutting and opening portion provided in the packaging box so that it can be used as a work mat for setup.

In order to solve the above-mentioned problems, the present invention provides a paper cartridge packaging box provided with a cutting and opening portion at a predetermined position, wherein the cutting and opening portion is arranged around the entire circumference of the box body in the vicinity of one end surface of the box. A cylinder cutting opening part provided over the other side of the box from the cutting start end perpendicular to the cylinder cutting opening part to the other side surface opposite to the one side surface, and in the vicinity of the other side surface of the other side surface A side cut opening portion provided in a range to reach the cutting end of the first and a development cutting opening portion that is orthogonal to the side cutting opening portion at the cutting end and reaches the front and rear folds of the other side surface. .

  In the case of illustration, the developing unit 55 is shown (see FIG. 4) as the cartsage packed by the packing box A (see FIG. 3) assembled as described above.

  The developing unit 55 is provided with a developer discharge port at one end and a developing roller on a side surface. Since the developer is sealed in the developing unit, a discharge port closing member 56 and a roller closing member (not shown) are provided to prevent the developer from leaking from the discharge port and the developing roller during transportation. Installed.

  The developing unit 55 is packed with a cover film 58 (see FIG. 4), and packed in the packing box A with cushioning materials 59 and 60 interposed at both ends thereof (see FIG. 3).

  A method for setting up the developing unit 55 packed as described above is as follows.

  First, as shown in FIG. 4, the lower end surface 11 of the packaging box A is erected on the floor surface F so that the discharge port closing member 56 side becomes the upper end surface 26 side of the packaging box A, or the operator Hold with your hand and stand upright.

  Then, the body part zipper 45 is pulled by pinching the knob 46 (see FIG. 3) (see the two-dot chain line in FIG. 3), and the upper overlap front surface 23, the right side surface 15 and the upper overlap rear surface 24 are unsealed. Further, the knob 40 (see FIG. 1) that appears by the opening is pinched and the trunk zipper 42 is pulled to open the lower overlap front surface 18, the left side surface 14, and the lower overlap front surface 19. Thereby, the upper end part 61 of a box is cut off and the box-shaped work mat B which is an incomplete box is formed (refer FIG. 4). The upper end portion of the developing unit 55 is exposed from the upper end of the box-shaped work mat B.

  When the upper end of the developing unit 55 is exposed, the cover film 58 is removed, the discharge port closing member 56 is removed, the seal applied to the discharged discharge port is removed, and the adapter 62 (see FIG. 5) is attached to the discharge port. To do. During this time, the developer discharge port is always maintained in the upward state, so there is no possibility that the internal developer leaks out. Even if it leaks out, the developer falls into the box-shaped work mat B, so that the surrounding floor surface is not soiled.

  Since the adapter 62 is closed until it is attached to the machine body, there is no possibility that the developer leaks after the adapter 62 is attached.

  Next, the upper work 61 is cut and removed as described above, and the box-shaped work mat B is laid down on the floor surface with the left side 14 facing upward (see FIG. 5).

  Thereafter, the cutting start end 51 that appears on the cut surface of the lower stacking drum cutting opening 39 is pinched, the side zipper 49 is pulled in the direction of arrow (see the two-dot chain line in FIG. 3), and the cutting end of the right side surface 15 on the opposite side Cut and open up to 52 (see FIG. 6).

  Then, the operator puts both hands on the groove portion after the side zipper 49 is removed, and opens the left side surface 14 to the left and right to unfold the box-shaped work mat B as shown by the arrow b in FIG. 5 (see FIG. 6). ). By the pushing-opening force, the perforations 54 on both sides are cut from the cutting end 52 formed on the right side surface 15 side to the folds 21 and 22, respectively.

  Thus, in a state where the developing unit 55 is laid down on the right side surface 15, the lower rear surface 19 (then) is surrounded on the left side of the developing unit 55 by a standing wall of a little less than half of the lower end surface 11 and a little less than half of the left side surface 14. The rear surface 24 is superimposed on the lower surface.) Is developed. Further, on the right side, a lower overlap front surface 18 (upper overlap front surface 23 overlaps the lower surface) surrounded by standing walls of the remaining half of the lower end surface 11 and the remaining half of the left side surface 14 is developed. By this development, a sheet-like work mat C is formed.

  A setup operation for removing the roller closing member (not shown) is performed on the sheet-like work mat C by replacing the developing unit 55 with an appropriate posture. Even if the developer leaks during this work, it can be received on the work mat C, so that the floor surface is not soiled. In particular, since there are standing walls formed by the lower end surface 11 and the left side surface 14 at the developed portions on both the left and right side portions, it is possible to prevent the developer from scattering to the outside at the standing wall portions.

In addition, in order to relieve stress such as bending and twisting applied to the cartridge that is the package,
After packing in the above-mentioned packing box A, it may be further stored in an outer box via a cushioning material to form double packing.

  Moreover, each part of the said cylinder cutting | disconnection opening parts 39 and 43, the side surface cutting | disconnection opening part 47, and the expansion | deployment cutting | disconnection opening part 53 may be comprised by sticking a cut tape on the back surface of a corrugated cardboard material.
