1. Field of the Invention
The present general inventive concept relates to a package unit for packing a developing agent container storing a developing agent for an image forming apparatus. More particularly, the present general inventive concept relates to a package unit usable with a developing agent container capable of preventing a developing agent stored in a developing agent storing portion of the developing agent container from leaning to one side thereof and cohering, a packing receptacle, and a method of packing a developing agent container in the packing receptacle.
2. Description of the Related Art
An image forming apparatus of an electrostatic latent image type, such as a laser printer, a facsimile machine, a composite apparatus, and the like, has been widely used not only in companies requiring a lot of printing work but also in homes due to high speed and high quality printing, and a relatively low price thereof.
The image forming apparatus of an electrostatic latent image type uses an exposure unit, such as an LSU, LED, etc., to scan a light beam onto a photosensitive medium, thereby forming electrostatic latent images thereon. Developing agent, such as toner, etc., is supplied to the photosensitive medium by a supplying member and a developing member, thereby developing the electrostatic latent images. The developed images are transferred onto a printing medium, and then fused thereon. After that, the printing medium having the fused image thereon is discharged. During this process, at least one member of the module referred to as a developing cartridge including the photosensitive medium, the developing member, the supplying member, and a developing agent storing portion, etc. may have a shorter lifespan compared to the rest of the image forming apparatus. Therefore, when one member of the developing cartridge becomes worn and useless, it needs to be replaced.
Accordingly, the developing cartridge is manufactured and sold separately from the rest of the image forming apparatus. Therefore, a user buys a new developing cartridge and can easily replace the worn developing cartridge with the new one.
The conventional packing receptacle 1 generally has no problem containing the developing cartridge 2.
However, when the packing receptacle 1 is carried so that the developing cartridge 2 is set vertically, i.e., the direction of its longitudinal axis is vertically aligned, a problem can arise (as illustrated at
The conventional packing receptacle 1 may have an inner packing and the outer packing box 6 enclosing it. The outer packing box 6 generally has a hexahedron shape. Therefore, when the packing receptacle 1 packed with the developing cartridge 2 is carried, one of six side surfaces of the outer packing box 6 becomes a bottom surface thereof. Therefore, the developing cartridge 2 in the packing receptacle 1 assumes six postures as any one of the six side surfaces of the outer packing box 6 is the bottom surface thereof. In two postures among the six postures thereof, the developing cartridge 2 is set in the longitudinal axial direction during distribution. In this case, the above-described problem may arise.
When the user mounts the developing cartridge 2 to the image forming apparatus, and turns on the image forming apparatus, a supplying member mixes or agitates the developing agent to supply the developing agent in the developing cartridge 2. If the developing agent has become overly cohesive, the supplying member needs a force larger than the cohesive force of the developing agent to supply the developing agent. Therefore, the supplying member is overloaded so that a driving motor, disposed in the main body of the image forming apparatus, to supply a driving force to the supplying member, cannot rotate.
No special measures have yet been taken to deal with the above described problems during distribution. Alternatively, a relatively large torque motor has been used to address the problem. However, this causes manufacturing costs to increase and compactness of the image forming apparatus to be lost.
The present general inventive concept provides a developing agent container package unit to prevent a developing agent stored in a developing agent container from being cohesive during distribution, a packing receptacle for a developing agent container, and a method of packing a developing agent container.

The developing agent container 110 may be a container to store a developing agent. Alternatively, the developing agent container 110 may include not only the container to store the developing agent but also at least one element of a printing unit, including a photosensitive medium 116 on which an electrostatic latent image is formed, a developing member 112 to supply the developing agent to the photosensitive medium 116, a supplying member 113 to supply the developing agent to the developing member 112, an agitator 114 to agitate or supply the developing agent to the supplying member 113 or the developing member 112, a charging member (not illustrated) to charge the photosensitive medium 116, a cleaning member (not illustrated) to clean the photosensitive medium 116, etc., according to the structure thereof. Hereinafter, the developing agent container 110 can be referred to as a developing cartridge having all or some of the members as described above.
An image forming apparatus (not shown except for the developing agent container 110) of an electrostatic latent image type uses an exposure unit (not shown), such as an LSU, LED, etc., to scan a light beam onto the photosensitive medium 116, thereby forming electrostatic latent images thereon. After the electrostatic latent images are formed, the supplying member 113 and developing member 112 supply the developing agent 115 such as toner to the photosensitive medium 116 to develop the electrostatic latent images. The developed images are transferred onto a printing medium and then fused thereon. The printing medium having images fused thereon is discharged outside. It should be noted that while the developing agent 115 is indicated to the exterior of the developing agent container 110 in
When the developing agent container 110 is a container to store the developing agent, the developing agent container 110 may have a length L in a longitudinal direction and a width W shorter than the length L. When the developing agent container 110 is a container combined with at least one element of a printing unit, the developing agent container 110 may have a length L and a width W. The length L may be parallel to a rotation axis of the element of the printing unit. According to the present embodiment, the length L of the developing agent container 110 is inclined with respect to a side of the package unit and/or a supporting member disposed between the package unit and the developing agent container 110.
The members of the developing agent container 110 may be formed substantially in a roller shape as illustrated in
When the developing agent container 110 is packed in the packing case 150 so that the direction of the longitudinal axis A thereof is aligned parallel to the axis B of
In this case, the minimized vertical component of gravitational force applied to the developing agent 115 of the developing agent container 110 may be represented using Formula 1.
F1=W sin θ(Kgf) <Formula 1>
Here, F1 is the force applied to the developing agent 115, W is the weight of the developing agent 115 in the gravitational direction F, and θ is an angle between the longitudinal axis A of the developing agent container 110 and the side surface 151 of the packing case 150. In this embodiment, θ is in a range of 0°<θ<90°.
As a result, when the developing agent container 110 is inclined at 45° with respect to the side surface 151 of the packing case 10, the vertical component of gravitational force, F1, applied to the developing agent 115 can be calculated as below.
In other words, F1=W sin 45°=0.707 W (Kgf). Therefore, the force F1 applied to the developing agent 115 of the developing agent container 110 packed in the developing agent container package unit 10 according to an exemplary embodiment of the present general inventive concept is smaller than the magnitude of the total gravitational force, that is, F1=W (Kgf) applied to the developing agent 115 of the developing agent container 110 packed by the conventional packing method (illustrated in
Hereinafter, the developing agent container package unit 10 according to exemplary embodiments of the present general inventive concept will be explained.
The packing case 150 receives the supporting member 100 to support the developing agent container 110. The packing case 150 may be formed substantially in a hexahedron shape so that a plurality of the developing agent container package units 10 can be easily piled up during distribution. In this exemplary embodiment, the developing cartridge, including the developing agent storing portion 111 storing the developing agent 115, the photosensitive medium 116, the developing member 112, and the supplying member 113, etc., may be used as the developing agent container 110 to contain the developing agent 115 therein.
The supporting member 100 is received in the packing case 150 and supports the developing agent container 110 to be inclined at a predetermined angle with respect to one side surface 151 of the packing case 150. As arrows illustrate in
The supporting member 100 may have portions to form at least one opening 130 around the receiving portion 120. At least one opening 130 may be used as a handle for easily carrying the supporting member 100 having the developing agent container 110 received thereon. Since the supporting member 100 may be easily molded, causing the weight of the supporting member 100 to be reduced over that of solid configurations, this embodiment has a decreased manufacturing cost. Also, the opening 130 can function as an air hole so that the supporting member 100 effectively absorbs impact. Furthermore, the supporting member 100 may have a grip portion 122 extending from the receiving portion 120 so that the supporting member 100, having the developing agent container 110 received within, can be easily taken out from the packing case 150.
In this exemplary embodiment, the supporting member 100 includes the lower supporting member 102 supporting a bottom surface of the developing agent container 110 and an upper supporting member 101 supporting a top surface of the developing agent container 110, so can be divided into two parts.
After the developing agent container 110 is received in the receiving portions 120 of the upper and lower supporting members 101 and 102, the supporting member 100 is inserted into the packing case 150 so that the process of packing the developing agent container 110 is completed to form the developing agent container package unit 10.
Therefore the developing agent container package unit 20 may be used not only when the developing agent container 110 is independently sold as expendable but also when the developing agent container 110 is packed and sold together with the image forming apparatus such as a printer, a facsimile machine, a composite machine, etc.
Hereinafter, a packing receptacle for the developing agent container 110 according to an exemplary embodiment of the present general inventive concept will be explained. The packing receptacle for the developing agent container 110 according to an exemplary embodiment of the present general inventive concept may include the packing case 150, 350 or 450 and the supporting member 100, 200, 300 or 400 except for the developing agent container 110 of the developing agent container package units 10, 20, 30 or 40 as described above. As described above, the supporting member 100, 200, 300, or 400 has the receiving portion 120, 220 or 320 to receive the developing agent container 110 and portions to form at least one groove 330 or opening 130 or 230 formed around the receiving portion 120, 220, or 320, so as to support the developing agent container 110 to be inclined with respect to one side surface of the packing case 150, 350 or 450 or the supporting member 200.
Hereinafter, the packing method for the developing agent container 110 according to an exemplary embodiment of the present general inventive concept will be explained with respect to
For packing the developing agent container 110, the packing receptacle is prepared (step 10). The packing receptacle in which the developing agent container 110 is packed may be substantially the same as the packing receptacle described above.
The developing agent container 110 is received inside the packing receptacle, so the developing agent container 110 is inclined with respect to one side surface of the packing receptacle (step 20). The developing agent container 110 may be inclinedly received in the packing receptacle using one of various methods as described above. At this time, the developing agent container 110 may be received in the packing receptacle so that the longitudinal axis direction A of the developing agent container 110, that is, the lengthwise direction of the developing agent storing portion 111 is inclined with respect to one side surface of the packing receptacle.
With the developing agent container package unit, the packing receptacle, and the packing method cooperatively acting according to an exemplary embodiment of the present general inventive concept, the developing agent container 110 is prevented from being set vertical to the ground during distribution. As a result, the cohesion of the developing agent 115 in the longitudinal axis direction A is decreased compared to the conventional developing agent container package unit. Therefore, after mounting the developing agent container 110 to the main body of the image forming apparatus, the user turns it on so that the supplying member 113 mixes or agitates the developing agent 115. At this time, because the developing agent 115 has a weak cohesive force, the force applied to the supplying member 113 is not large. Therefore, the supplying member 113 is not overloaded so that the driving motor (not illustrated) disposed in the main body (not illustrated) can rotate.
In other words, even when the conventional developing agent container 110, motor, and main body are used without additional device or cost, the problem caused by the cohesion of the developing agent 115 can be solved.
Also, the packing receptacle according to an exemplary embodiment of the present general inventive concept can maximally absorb vibration and impact from outside so that vibration and impact transmitted to the developing agent container 110 is minimized.
Furthermore, the supporting member may have portions to form at least one opening around the receiving portion. At least one opening may be used as a handle when the user carries the supporting member having the developing agent container 110 received thereon. Also, the opening may cause the supporting member to be easily molded, weight of the supporting member to be reduced and the manufacturing cost of the supporting member to be decreased. Also, the opening can function as an air hole so that the supporting member effectively absorbs impact. Furthermore, the supporting member may have the grip portion extending from the supporting member beside the supporting member so that the supporting member having the developing agent container received thereon can be easily taken out from the packing case.
Although a few embodiments of the present general inventive concept have been illustrated and described, it will be appreciated by those skilled in the art that changes may be made in these embodiments without departing from the principles and spirit of the general inventive concept, the scope of which is defined in the appended claims and their equivalents.
