And a rectangular top portion 13 that closes the other open end of the portion 11.

  Note that the packaging box 10 may be provided with flaps and the like connected to the side walls as in the case of an existing cardboard box formed by folding and assembling a paper blank, and both ends of the cylindrical main body 11 are connected to the bottom 12 and the top. The structure is not limited as long as it can be blocked by the portion 13. As will be described later, by breaking the perforation that is a weak line provided in the cylindrical main body 11, the cylindrical main body 11 is divided into two parts except for one side wall, and the packaging box 10 is opened and accommodated. The toner cartridge 1 can be taken out.

  When the toner cartridge 1 is packed (accommodated) in the internal space, the packing box 10 is parallel to the rotation shaft 41 of the toner discharge screw 22 and is closest to the toner discharge portion 21b. A toner discharge side wall 10b (second side wall) that is orthogonal to the rotation axis of the toner discharge screw 22 and is closest to the toner discharge port 52 provided on the end side of the toner discharge unit 21b, and a toner discharge side wall 10a. And a side wall 10d (fourth side wall) facing the toner discharge side wall 10b.

  A perforation line 20a, a perforation line 20b, and a perforation line 20c, which are weak lines, are formed on the toner discharge portion side wall 10a, the toner discharge port side wall 10b, and the side wall 10c, respectively.

  The perforation 20a extends in the width direction from the side of the toner discharge portion side wall 10a that is connected to the side wall 10d and extends to the side of the toner discharge portion side wall 10a that is connected to the toner discharge port side wall 10b. It is formed linearly over the entire width of the side wall 10a. The perforation 20b is connected to the perforation 20a, extends in the width direction from the side of the toner discharge port side wall 10b that is connected to the toner discharge side wall 10a, and is connected to the side wall 10c of the toner discharge port side wall 10b.

The perforation 20c is continuous with the perforation 20b and extends in the width direction from a side portion of the side wall 10c that is connected to the toner discharge side wall 10b to a side portion of the side wall 10c that is connected to the side wall 10d over the entire width of the side wall 10c. It is formed in a straight line.

  Since the perforations 20a to 20c are all formed in a row, one perforation 20 extending from the toner discharge side wall 10a, the toner discharge port side wall 10b, and the side wall 10c is formed.

  On the inner wall surfaces (inner side of the packing box 10) of the toner discharge side wall 10a, the toner discharge side wall 10b, and the side wall 10c, one tear is formed along the perforation 20a, the perforation 20b, and the perforation 20c. The thread 14 is fixed.

  Of both ends of the tear yarn 14, the end on the side where the toner discharge side wall 10 a and the side wall 10 d are connected extends to the outside of the packaging box 10 through the side wall and extends to the outside. A handle 14a is provided at the end. The handle 14a is formed in an annular shape having a diameter that allows a human finger to enter.

  The user who wants to open the packaging box 10 puts his finger on the handle 14a and pulls it away from the packaging box 10 so that the tearing yarn 14 that is fixed cuts the perforations 20a to 20c sequentially, The toner discharge unit side wall 10a, the toner discharge port side wall 10b, and the side wall 10c are each divided into two parts, and the packaging box 10 is opened.

  FIG. 5 is a schematic diagram showing a state of cutting the toner discharge side wall 10a, and FIG. 6 is a schematic diagram showing a state of cutting the toner discharge side wall 10b. As shown in FIG. 5, when the user opens the packaging box 10, the user places the side wall 10 d on the desk 5 with the side wall 10 d down so that the side wall 10 d with no perforation is in contact with the upper surface of the desk 5. Put. In this state, since the toner discharge port side wall 10b is on the upper side, the toner discharge port 52 of the accommodated toner cartridge 1 is positioned on the upper side.

  While holding the packing box 10 with one hand, the tearing thread 14 is pulled away from the toner discharge side wall 10a with the other hand to cut the perforations 20a formed on the toner discharge side wall 10a. The toner in the toner discharge portion 21b is crushed by the irregular vibration generated when the toner discharge portion side wall 10a made of corrugated cardboard is torn by the tear yarn 14 and the weight of the toner itself. Then, it falls away from the toner discharge port 52 by its own weight.

  Subsequently, the tear yarn 14 is further pulled in a direction away from the toner discharge port side wall 10b, and the perforation 20b formed on the toner discharge port side wall 10b is cut.

  The toner in the toner discharge portion 21b is further crushed by the irregular vibration generated when the toner discharge side wall 10b made of corrugated cardboard is torn and the own weight of the toner itself. Drop away from the discharge port 52. Finally, the tear yarn 14 is further pulled in the same manner as heretofore to cut the perforation 20c formed on the side wall 10c. Also at this time, the toner in the toner discharge portion 21b is further crushed by the irregular vibration caused by tearing and the weight of the toner itself, and the crushed toner falls away from the toner discharge port 52 by its own weight.

  By pulling the tear yarn 14, all the perforations 20a to 20c are cut, and the three side walls of the toner discharge portion side wall 10a, the toner discharge port side wall 10b, and the side wall 10c are each divided into two portions. Thereafter, when the bottom portion 12 or the top portion 13 is turned down and placed on the top surface of the desk 5, the divided one side portion is grasped by hand and the side wall 10d is bent outward, the entire toner cartridge 1 is exposed. Therefore, the toner cartridge 1 housed in the other divided part can be taken out.

  The above-described opening procedure is an example, and other procedures may be used. For example, the packaging box 10 is placed on the desk 5 with the toner discharge side wall 10a facing up, and the tear yarn 14 is pulled with the other hand while the toner discharge side wall 10a is pressed from above with one hand. As a result, the perforation 20a of the toner discharge portion side wall 10a is cut. The toner in the toner discharge portion 21b is crushed by the irregular vibration generated when the toner discharge portion side wall 10a made of corrugated cardboard is torn by the tearing yarn 14 and the weight of the toner itself. It falls toward the accommodating part 21a.

  Next, the attitude of the packaging box 10 is changed, the packaging box 10 is placed on the desk 5 with the toner discharge port side wall 10b facing up, and the toner discharge port side wall 10b is pressed from above with one hand. By pulling the tear yarn 14 with the other hand, the perforation 20b of the toner discharge port side wall 10b is cut. The toner near the toner discharge port 52 is crushed by the irregular vibration generated when the toner discharge port side wall 10b made of corrugated cardboard is torn by the tearing yarn 14, and the weight of the toner itself. The toner drops in a direction away from the toner discharge port 52.

  Further, by pulling the tearing thread 14, the perforation 20c of the side wall 10c is cut, the one side part divided is grasped by hand, the side wall 10d is bent outwardly, and the other side part is stored. Take out the toner cartridge 1.

  As described above, the packing box 10 according to the present invention has the toner pressed by the toner discharge portion 21b of the toner cartridge 1 due to the irregular vibration continuously generated when the weakening line formed on the side wall is cut. Can be crushed. Therefore, the user only needs to perform the essential operation of opening the packing box 10 and can easily crush the toner in the toner cartridge 1.

(Second Embodiment)
The present invention breaks the toner in the toner cartridge 1 by cutting the weakening lines provided on the toner discharge side wall 10a, the toner discharge port side wall 10b, and the side wall 10c when the packaging box 10 is opened. Therefore, the present invention is not limited to the combination of the perforation and the tearing thread as described above, and can be opened without using the tearing thread by forming a plurality of perforations on each side wall.

  FIG. 7 is a perspective view showing an appearance of the packaging box 10 according to the second embodiment of the present invention. In the second embodiment, instead of one perforation and one tearing thread, two parallel perforations extending from the toner discharge side wall 10a, the toner discharge port side wall 10b, and the side wall 10c are opened. This is the same as the first embodiment except that it is formed as a weak line. Since the configuration other than the two parallel perforations is the same as that of the first embodiment, the same reference numerals are assigned and description thereof is omitted.

  Two parallel perforations 30 extending between the toner discharge side wall 10a, the toner discharge side wall 10b, and the side wall 10c are formed on the toner discharge side wall 10a, the toner discharge side wall 10b, and the side wall 10c, respectively. The eye 30a, the perforation 30b, and the perforation 30c are connected.

  The perforation 30a is composed of two parallel perforations, and extends in the width direction from the side of the toner discharge portion side wall 10a connected to the side wall 10d and extends in the width direction of the toner discharge portion side wall 10a. Is formed linearly over the entire width of the toner discharge side wall 10a up to the side connected to the toner discharge side. The perforation 30b is composed of two parallel perforations. Each perforation is connected to each perforation of the perforation 30a. From the side of the toner discharge port side wall 10b connected to the toner discharge unit side wall 10a. The toner discharge port side wall 10b extends in the width direction and is linearly formed over the entire width of the toner discharge port side wall 10b up to a side portion connected to the side wall 10c. The perforation 30c is composed of two parallel perforations, each perforation is connected to each perforation of the perforation 30b, and extends in the width direction from the side of the side wall 10c that is connected to the toner discharge side wall 10b. The side wall 10c is linearly formed over the entire width of the side wall 10c up to the side connected to the side wall 10d.

  A perforation 30 consisting of two parallel perforations is similar to a so-called zipper for opening a paper carton or the like. The interval between the two parallel perforations may be selected according to various conditions such as the size of each side wall and the force required for cutting, so that appropriate vibration can be applied to the toner cartridge 1 during cutting. It is preferable to select.

  Of the both ends of the perforation 30, for example, at the end on the side where the toner discharge portion side wall 10a and the side wall 10d are connected, a zipper sandwiched between two perforations so that the user can easily pinch with a finger You may make it the state which cut off the corner | angular part of an edge part, or bend | folded a little zipper edge part outward, and the edge part floated.

  Similarly to the first embodiment, the packaging box 10 of the second embodiment is also placed on a desk or the like, holding the packaging box 10 with one hand, pinching the end of the zipper part with the other hand, and from the side wall By pulling in the separating direction, the two perforations are cut simultaneously, and the zipper portion sandwiched between the two perforations is separated from the side wall. By cutting the entire perforation 30, the three side walls of the toner discharge portion side wall 10a, the toner discharge port side wall 10b, and the side wall 10c are each divided into two parts. Thereafter, when the bottom portion 12 or the top portion 13 is placed on a desk with the bottom portion 12 or the top portion 13 down, the divided one side portion is grasped by hand and the side wall 10d is bent outward, the entire toner cartridge 1 is exposed. Therefore, it is possible to take out the toner cartridge 1 housed in the other divided part.

  When the perforation 30 is cut, irregular vibrations are continuously generated and vibrations are applied to the toner cartridge 1, so that the user only needs to perform the essential work of opening the packaging box 10, The toner in the toner cartridge 1 can be easily crushed.

(Third embodiment)
FIG. 8 is a perspective view showing an appearance of the packaging box 10 according to the third embodiment of the present invention. In the third embodiment, a chain perforation in which circular perforations are arranged in a straight line instead of one perforation, one tear thread, and two parallel perforations is weakened for opening. Except for being formed as a line, it is the same as the first embodiment and the second embodiment. Since the configuration other than the chain perforations is the same as that of the first embodiment and the second embodiment, the same reference numerals are given and description thereof is omitted.

  The chain perforations 40 extending between the toner discharge side wall 10a, the toner discharge port side wall 10b, and the side wall 10c are formed on the toner discharge side wall 10a, the toner discharge port side wall 10b, and the side wall 10c, respectively. 40a, a chain perforation 40b, and a chain perforation 40c are connected.

  The chain perforation 40a is formed by arranging a plurality of circular perforations in a straight line, and extends in the width direction from the side of the toner discharge portion side wall 10a that is connected to the side wall 10d. It is formed over the entire width of the toner discharge side wall 10a up to the side connected to the toner discharge side wall 10b. The chain perforation 40b is formed by arranging a plurality of circular perforations in a straight line, is continuous with the chain perforation 40a, and has a width from a side of the toner discharge port side wall 10b that is connected to the toner discharge unit side wall 10a. The toner discharge port side wall 10b is formed over the entire width of the toner discharge port side wall 10b up to the side of the toner discharge port side wall 10b connected to the side wall 10c. The chain perforation 40c has a plurality of circular perforations arranged in a straight line, is continuous with the chain perforation 40b, and extends in the width direction from the side of the side wall 10c that is connected to the toner discharge port side wall 10b. The side wall 10c is formed over the entire width of the side wall 10c up to the side connected to the side wall 10d.

  The part surrounded by one circular perforation is cut by the user holding the finger with a finger or the like, and the circular pushing piece is separated from the side wall. If all the circular perforations of the chain perforation 40a are formed so as to be adjacent to each other, all the pushing pieces are separated, so that the toner discharge portion side wall 10a is divided into two parts. Similarly, if all the circular perforations of the chain perforation 40b and the chain perforation 40c are formed adjacent to each other, all the pushing pieces are separated, so that the toner discharge port side wall 10b and Each side wall 10c is divided into two parts.

  The pushing pieces separated from the side wall become unnecessary paper scraps, but if the separated pushing pieces are connected to each other, they are easily discarded. It is preferable that the portion where the adjacent circular perforations are in contact with each other is a portion where a part of the perforations is not formed because the pushed pieces are separated from the side wall in a connected state.

  The circular perforation may be a perfect circle or an ellipse. The diameter of the circle or the lengths of the major and minor axes may be selected according to various conditions such as the size of each side wall and the force required for pushing, and appropriate vibration is imparted to the toner cartridge 1 during pushing. It is preferable to select such that it is possible.

  The packaging box 10 of the third embodiment is placed on a desk or the like and opened as in the first and second embodiments, but each circular perforation of the chain perforation 40 is cut. In order to apply a pushing force, the side perforated with a chain perforation to be used for cutting is placed on the desk, and it is easy to apply a force to push from the top to the bottom. Perforations can be cut.

  For example, the packing box 10 is placed on the desk 5 with the toner discharge portion side wall 10a facing up, and the circular perforations are cut by pushing in the portions surrounded by the circular perforations of the chain perforations 40a from above. The pushing piece is separated from the side wall. This is continued until all the circular perforations of the chain perforations 40a are cut. Since vibration is generated when one circular perforation is cut, intermittent vibration is generated by cutting all the circular perforations of the chain perforation 40a. Due to the intermittent vibration and the weight of the toner itself, the toner in the toner discharge portion 21b is crushed and the crushed toner falls toward the storage portion 21a.

  Next, the posture of the packaging box 10 is changed, and the packaging box 10 is placed on the desk 5 with the toner discharge port side wall 10b facing up, and the portion surrounded by each circular perforation of the chain perforation 40b is placed on the top. Is pushed into the circular perforation, and the pushing piece is separated from the side wall. This is continued until all the circular perforations of the chain perforations 40b are cut. Since vibration is generated when one circular perforation is cut, intermittent vibration is generated by cutting all the circular perforations of the chain perforation 40b. Due to the intermittent vibration and the weight of the toner itself, the toner near the toner discharge port 52 is crushed, and the crushed toner falls in a direction away from the toner discharge port 52.

  Further, the posture of the packaging box 10 is changed, the packaging box 10 is placed on the desk 5 with the side wall 10c facing up, and the circular perforation of the chain perforation 40c is pushed in from above, thereby circular The perforation is cut and the pushing piece is separated from the side wall. This is continued until all the circular perforations of the chain perforations 40c are cut. Since vibration is generated when one circular perforation is cut, intermittent vibration is generated by cutting all the circular perforations of the chain perforation 40c. The toner is further crushed by the intermittent vibration and the weight of the toner itself.

  When the chain perforations 40 are cut, vibrations are intermittently generated and vibrations are applied to the toner cartridge 1, so that the user only needs to perform the essential work of opening the packing box 10 and the toner. The toner in the cartridge 1 can be easily crushed.

  By making the size of each circular perforation of the chain perforation 40 the same, the magnitude of each vibration generated intermittently can be made substantially the same. Moreover, the magnitude | size of each vibration produced intermittently can also be varied by varying the magnitude | size of each circular perforation of the chain | strand-shaped perforation 40. FIG.

  In each of the above embodiments, the packaging box 10 is preferably made of cardboard, but is not limited to cardboard, and may be made of cardboard or other thick paper.
