First Exemplary Embodiment
FIG. 1 is an overall view of a packaging container according to a first exemplary embodiment of the present invention, illustrating a state in which components are taken out of the outer container.
FIGS. 2A and 2B illustrate the packaging container according to the first exemplary embodiment, FIG. 2A illustrating a plan view illustrating a state in which upper part of the outer container has been opened from a packaged state, and FIG. 2B illustrating a sectional view illustrating the packaged state.
Referring to FIGS. 1 to 2B, a packaging container 1 according to a first exemplary embodiment includes an outer box 2, which is an example of an outer container, having a rectangular-parallelepiped shape. The outer box 2 according to the first exemplary embodiment is made of corrugated fiberboard. However, the outer box 2 is not limited to a corrugated fiberboard box, and may be a container box of any known type, such as a plastic box. The outer box 2 has a bottom portion 2a; front, back, left, and right side portions 2b; and lid portions 2c that are integrally formed with upper ends of the side portions 2b. A containing space 3 is a space formed by being surrounded by the bottom portion 2a, the side portions 2b, and the lid portions 2c when the lid portions 2c are closed. The lid portions 2c are examples of a closing portion. When the lid portions 2c are open as illustrated in FIG. 2A, a passage opening 3a is formed at the top of the containing space 3.
A printer 4, which is an example of an object and an example of an image forming apparatus, is contained in the containing space 3 in the outer box 2. The printer 4 includes an apparatus body 4a, a sheet feed tray 4b, and an output tray 4c. The sheet feed tray 4b, which is an example of a containing section for containing a medium on which an image is to be recorded, is removably supported by a lower part of the apparatus body 4a. The output tray 4c, which is an example of an output section to which a medium on which an image has be recorded is output, is formed on an upper surface of the apparatus body 4a.
Referring to FIG. 2A, the printer 4 according to the first exemplary embodiment has a length La in the left-right direction that is larger than a length Lb in the front-back direction. That is, for the printer 4 and the outer box 2 that contains the printer 4, the left-right direction is the longitudinal direction and the front-back direction is the transversal direction.
FIG. 3 illustrates the packaging container according to the first exemplary embodiment in a state in which an upper cushioning member and an object have been taken out of the outer container that has been in the packaged state.
FIG. 4 illustrates a state after an object according to the first exemplary embodiment has been taken out of the outer container and before the object is taken out of a packaging bag.
Referring to FIGS. 1 to 4, the printer 4 is contained in the outer box 2 in a state in which the printer 4 is contained in a plastic bag 6, which is an example of a packaging bag. The plastic bag 6 according to the first exemplary embodiment includes a containing portion 7, an opening portion 8, and a pair of handle portions 9. The printer 4 is contained in the containing portion 7. The opening portion 8 allows the printer 4 to pass therethrough when the printer 4 is taken out of the containing portion 7.
The plastic bag 6 according to the first exemplary embodiment is made of polyethylene. However, the material of the plastic bag 6 is not limited thereto, and may be another known plastic. The thickness of the plastic bag 6 may be in the range of about 0.02 to 0.1 mm. In particular, if the weight of the printer 4 is about 5 kg, a polyethylene film having a thickness in the range of about 0.04 to 0.06 mm may be used. However, the plastic bag 6 may be made of any plastic material having any thickness as long as the plastic bag 6 has a strength with which the plastic bag 6 is prevented from being broken when the handle portions 9 are held while the printer 4 is contained in the plastic bag 6.
In the plastic bag 6 according to the first exemplary embodiment, each of the pair of handle portions 9 has a strip-like member. Ends of the strip-like member of each of the pair of handle portions 9 are connected to the containing portion 7 at two positions at the edge of the opening portion 8 that are separated from each other in the front-back direction. Therefore, each of the handle portions 9 has a loop-like shape, and a space 9a into which a user may insert his/her finger or arm is formed. In the first exemplary embodiment, the distance between the handle portions 9 in the left-right direction is larger than the distance between connection portions 9b at which the handle portions 9 are connected to the containing portion 7 in the front-back direction. That is, the pair of handle portions 9 according to the first exemplary embodiment are disposed on both sides in the longitudinal direction.
In the first exemplary embodiment, the handle portions 9 are integrally formed with the containing portion 7 in order to reduce production cost. Alternatively, strip-shaped handle portions that are independent members may be connected to the containing portion 7 by using adhesive, adhesive tape, or the like.
As illustrated in FIGS. 3 and 4, each of the handle portions 9 according to the first exemplary embodiment has a length with which the handle portion 9 is allowed to protrude away from the upper surface of the printer 4, which is a surface of the printer 4 adjacent to the passage opening 3a, toward the passage opening 3a when the plastic bag 6 containing the printer 4 is contained in the outer box 2 and the handle portion 9 is extended in an upward direction through the passage opening 3a.
Moreover, each of the handle portions 9 according to the first exemplary embodiment has a length L1 that is equal to or larger than half the length La of the printer 4 along the passage opening 3a, when the plastic bag 6 containing the printer 4 is contained in the outer box 2 and the handle portion 9 is extended in a horizontal direction along the passage opening 3a. That is, L1≧La/2, where L1 is the length of the handle portion 9 and La is the width of the printer 4 in the longitudinal direction. As illustrated in FIG. 2B, when the passage opening 3a of the outer box 2 is closed, the handle portions 9 according to the first exemplary embodiment are contained in the outer box 2 in a state in which the handle portions 9 extend in the horizontal direction along the passage opening 3a. As illustrated in FIG. 2A, each of the handle portions 9 on the left and right sides, which is configured such that L1≧La/2, are folded in such a way that ends of the handle portions 9 overlap in the up-down direction in a state in which the handle portions 9 extend in the horizontal direction.
As illustrated in FIG. 4, in the handle portions 9 according to the first exemplary embodiment, the positions of the connection portions 9b, at which the handle portions 9 and the containing portion 7 are connected each other, are located at positions separated away from the surface of the printer 4 adjacent to the passage opening 3a toward the passage opening 3a, when the plastic bag 6 containing the printer 4 is contained in the outer box 2 and the handle portions 9 are extended upward. That is, in the first exemplary embodiment, the size of the plastic bag 6 is determined so that corners 4d of the upper surface of the printer 4 are not exposed to the outside and covered with the plastic bag 6 when the printer 4 is contained in the plastic bag 6. Therefore, when the outer box 2 is closed as illustrated in FIG. 2B, the connection portions 9b of the plastic bag 6 according to the first exemplary embodiment are disposed further inward than the corners 4d of the outer ends of the printer 4.
Referring to FIGS. 2B, 3, and 4, when the handle portions 9 of the plastic bag 6 according to the first exemplary embodiment extend in the horizontal direction along the passage opening 3a, excess portions 7a of the containing portion 7 are disposed outside the connection portions 9b and portions 7b of the containing portion 7 extending along the outer surface of the printer 4. Therefore, as illustrated in FIG. 3, when the handle portions 9 are held together (by a single hand of a user, for example), the excess portions 7a of the containing portion 7 are folded into strip-like shapes so as to extend along extension lines of the handle portions 9 and along the outer surface of the printer 4.
Referring to FIGS. 1 to 2B, in the packaging container 1 according to the first exemplary embodiment, when the printer 4 contained in the plastic bag 6 is contained in the outer box 2, a cushioning member 11, which is an example of a cushioning member for absorbing an external force, is disposed between the plastic bag 6 and the outer box 2. The cushioning member 11 according to the first exemplary embodiment includes four lower cushions 12 and an upper cushion 13. The lower cushions 12 are disposed at four corners in a bottom part of the outer box 2. The upper cushion 13, which is an example of an inner packing member, is disposed on an upper part of the printer 4.
Referring to FIGS. 1 to 2B, the upper cushion 13 includes a frame portion 13a and cushioning bodies 13b. The frame portion 13a has a frame-like shape and extends around the outer periphery of the passage opening 3a. The cushioning bodies 13b are formed at four corners of a bottom surface of the frame portion 13a and have shapes that are vertically symmetric with the lower cushions 12. A bridge portion 13c, which is an example of a supporting portion, is formed in a central part of the frame portion 13a in the left-right direction. A pair of left and right opening portions 13d are formed between the bridge portion 13c and the frame portion 13a so as to extend through the upper cushion 13 in the up-down direction.
Referring to FIGS. 2A and 2B, in the packaging container 1 according to the first exemplary embodiment, when the lid portions 2c are closed, the left and right handle portions 9 are supported in such a way that the handle portions 9 pass through the left and right opening portions 13d of the upper cushion 13 and the lower surfaces of the handle portions 9 are supported by the bridge portion 13c.
Referring to FIGS. 2A and 2B, the thickness and the size of the cushioning member 11 according to the first exemplary embodiment are determined so that the width of a gap S1 between the inner surface of the outer box 2 and the outer surface of the printer 4 is 20 mm. The width of the gap S1 is not limited to 20 mm. The width of the gap S1 may be equal to or smaller than 30 mm, which is smaller than 40 mm used for existing packaging containers, or may be equal to or smaller than 10 mm depending on the processing accuracy of the cushioning member 11.
The cushioning member 11 according to the first exemplary embodiment may be made of any appropriate known material, such as styrofoam or corrugated fiberboard.
Functions of First Exemplary Embodiment
FIGS. 5A to 5C illustrate the function of the first exemplary embodiment, FIG. 5A illustrating a state in which an inner packing member is started to be taken out, FIG. 5B illustrating a state in which the inner packing member is being taken out, FIG. 5C illustrating a state in which the inner packing member has been taken out.
To take the printer 4 out of the packaging container 1 according to the first exemplary embodiment having the structure described above, the lid portions 2c of the outer box 2 are opened first and the packaging container 1 enters a state illustrated in FIG. 2A. The upper cushion 13, which is disposed nearer to the passage opening 3a than the printer 4, is taken out before the printer 4 is taken out. As illustrated in FIG. 5A, when the upper cushion 13 is started to be taken out, the handle portions 9, which are supported by the bridge portion 13c of the upper cushion 13, are lifted as the upper cushion 13 moves. After a state illustrated in FIG. 5B, when the upper cushion 13 has been taken out as illustrated in FIG. 5C, the handle portions 9 that have been lifted lean against each other. When an operator holds and lifts the two handle portions 9, the printer 4 is taken out of the outer box 2 together with the plastic bag 6. Then, the printer 4 is moved to an installation position while holding the handle portions 9. As illustrated in FIG. 4, the printer 4 is taken out of the plastic bag 6 through the opening portion 8, and the printer 4 is installed in place.
FIG. 6 illustrates a state in which an object is being taken out of an existing packaging container.
Referring to FIG. 6, with the existing structure described in Japanese Unexamined Patent Application Publication No. 2009-35269, it is necessary for a user to insert his/her hands 04 into a gap between the outer box 01 and the object 03 to take an object 03 out of the outer box 01 because the packaging bag 02 does not have handles. Therefore, the existing technology has a problem in that it is impossible for a user to insert his/her hands 04 if the gap between the outer box 01 and the object 03 is too narrow and a problem in that an accident that the object 03 is dropped and broken may occur if the user tries to forcibly take out the object 03. In order to allow a user to inert his/her hands 04 into the gap, the width of the gap between the outer box 01 and the object 03 has been generally set equal to or larger than about 40 mm with consideration of the thickness of a human hand. Therefore, in order to allow a user to insert his/her hands 04 into both sides as illustrated in FIG. 6, it is necessary that the size of the outer box 01 be larger than that of the object 03 by about 40 mm×2=80 mm, so that there has been a problem in that the size of the package box 01 is increased.
In contrast, with the first exemplary embodiment, the plastic bag 6, which is used to cover the outer surface of the printer 4 to protect the printer 4 from dust, has the handle portions 9, so that it is possible for a user to take the printer 4 out of the packaging container 1 by holding the handle portions 9 and lifting the plastic bag 6. Therefore, the gap S1 between the outer box 2 and the printer 4 may be narrower than that of existing packaging containers, so that it is possible to reduce the size of the outer box 2 as compared with those of existing packaging containers. By reducing the size of the outer box 2, it is possible to store a larger number of packaging containers in a warehouse, the area needed to store the packaging containers is reduced, and the cost of storing the packaging containers is reduced. Moreover, by reducing the size of the outer box 2, the material cost of the outer box 2 is reduced, and the volume of the outer box 2 discarded after installing the printer 4 is reduced, which leads to waste reduction
With the existing technology, when handling an object that is relatively large and heavy, such as the printer 4, it is necessary for an operator to lift the object with both hands to take the object out of the outer box 2. Therefore, if there is large friction between the printer 4 and the outer box 2 due to static electricity or the like, it is difficult for a single operator to hold the outer box 2 with his/her hands occupied. In such a case, two operators are necessary, so that the operability is impaired. If an operator crouches and lifts the object with both hands, the operator may suffer from back pain.
In contrast, with the first exemplary embodiment, it is possible for an operator to hold the two handle portions 9 with one hand and take out the printer 4 while holding the outer box 2 with the other hand, and thereby the operability is improved.
With first exemplary embodiment, the handle portions 9 are lifted together with the upper cushion 13 when the upper cushion 13 is being removed. Therefore, as compared with a case where the handle portions 9 are not lifted, a user may easily insert his/her fingers into the spaces 9a of the handle portions 9. In particular, in first exemplary embodiment, a condition L1≧La/2 is satisfied, so that the ends of the handle portions 9 may easily contact each other and lean against each other. Therefore, as compared with a case where the length of the handle portions 9 are set such that L1<La/2, the handle portions 9 may easily lean against each other, and thereby a user may easily grasp the handle portions 9.
Even if the ends of the handle portions 9 slip over each other and the handle portions 9 fail to lean against each other, as long as the handle portions 9 have been lifted, the handle portions 9 tend to remain in a state in which the handle portions 9 are separated away from the upper surface of the printer 4, i.e., in a raised state, as compared with the case where the handle portions 9 are not lifted. Therefore, as compared with the case where the handle portions 9 are not lifted, a user may easily lift the two handle portions 9 in the raised state and hold the two handle portions 9 with a single hand.
Moreover, in the first exemplary embodiment, the handle portions 9 are lifted when the upper cushion 13 is being removed. Therefore, an operator may easily see the handle portions 9 that are being lifted, and thereby the operator may easily notice that the plastic bag 6 has the handle portions 9. If the handle portions 9 are not lifted, it is possible that the operator performs an operation without noticing the handle portions 9. In contrast, with first exemplary embodiment, the operator may easily notice the handle portions 9 and easily use the handle portions 9, and thereby the operability of the printer 4 is improved.
As illustrated in FIGS. 3 and 4, in the first exemplary embodiment, the size of the plastic bag 6 has a margin when the printer 4 is contained in the plastic bag 6, so that the containing portion 7 has the excess portions 7a when the handle portions 9 are held and lifted. The excess portions 7a of the containing portion 7 are disposed so as to overlap the outer sides of the portions 7b of the containing portion 7 extending along the outer surface of the printer 4. Therefore, the strength of the plastic bag 6 is increased because a force that is generated when the handle portions 9 are held and lifted is applied to both the excess portions 7a and the portions 7b extending along the outer surface. As a result, the plastic bag 6 is not easily broken when the handle portions 9 are held and lifted, and occurrence of an accident such that the plastic bag 6 is broken and the printer 4 is dropped and broken during operation is reduced.
In particular, in the first exemplary embodiment, as illustrated in FIG. 2B, when the printer 4 is contained in the outer box 2, the excess portions 7a have strip-like shapes and extend along the outer sides of the portions 7b extending along the outer surface of the printer 4. Therefore, when the handle portions 9 are lifted in this state, strip-shaped portions in which the excess portions 7a and the portions 7b extending along the outer surface of the printer 4 overlap are naturally and easily formed.
In the first exemplary embodiment, the two handle portions 9 are disposed so as to be separated from each other in the longitudinal direction. As compared with the case where the handle portions 9 are disposed on both sides in the transversal direction, the excess portions 7a are easily formed into large strips. Therefore, as compared with the case where the handle portions 9 are disposed on both sides in the transversal direction, the plastic bag 6 is not easily broken.
In the first exemplary embodiment, the connection portions 9b between the handle portions 9 and the containing portion 7 are disposed above the corners 4d of the printer 4, so that the corners 4d are not exposed to the outside when the printer 4 is contained in the plastic bag 6. Therefore, as compared with the case where the corners 4d of the printer 4 are exposed to the outside, the printer 4 is not easily dropped out of the containing portion 7.
Second Exemplary Embodiment
A second exemplary embodiment of the present invention will be described below. In the description of the second exemplary embodiment, the elements the same as those of the first exemplary embodiment will be denoted by the same numerals and detailed description of such elements will be omitted.
The second exemplary embodiment differs from the first exemplary embodiment in the following respects, but has the same structure as that of the first exemplary embodiment in other respects.
FIG. 7 is a plan view of a packaging container according to the second exemplary embodiment, corresponding to FIG. 2A of the first exemplary embodiment.
Referring to FIG. 7, in a packaging container 1 according to the second exemplary embodiment, two handle portions 9 are contained so as not to overlap and so as to be displaced from each other in the front-back direction.
Functions of Second Exemplary Embodiment
With the packaging container 1 according to the second exemplary embodiment having the structure described above, as with the first exemplary embodiment, a user may easily notice the presence of the handle portions 9 because the handle portions 9 are lifted when the upper cushion 13 is being removed. If the handle portions 9 lean against each other, the user may more easily grasp the handle portions 9 than in the case where the handle portions 9 do not lean against each other, and thereby the operability is improved. Even if the handle portions 9 do not lean against each other, the handle portions 9 tend to be raised above the upper surface of the printer 4. Therefore, a user may easily lift the handle portions 9 as compared with the case where the handle portions 9 are not raised, and thereby the operability is improved.
Third Exemplary Embodiment
A third exemplary embodiment of the present invention will be described below. In the description of the third exemplary embodiment, the elements the same as those of the first exemplary embodiment will be denoted by the same numerals and detailed description of such elements will be omitted.
The third exemplary embodiment differs from the first exemplary embodiment in the following respects, but has the same structure as that of the first exemplary embodiment in other respects.
FIGS. 8A and 8B illustrate a packaging container according to a third exemplary embodiment, FIG. 8A illustrating a plan view corresponding to FIG. 2A of the first exemplary embodiment, and FIG. 8B illustrating a sectional view corresponding to FIG. 2B of the first exemplary embodiment.
Referring to FIGS. 8A and 8B, in a packaging container 1 according to the third exemplary embodiment, the handle portions 9 of the plastic bag 6 pass through gaps between the outer surfaces of the cushioning bodies 13b of the upper cushion 13 and the side portions 2b of the outer box 2, and the handle portions 9 are disposed on the upper side of the upper cushion 13. That is, the handle portions 9 extend along the outer sides of the upper cushion 13, and the handle portions 9 are supported on the upper side the upper cushion 13. In the third exemplary embodiment, the upper cushion 13 does not have the bridge portion 13c.
Functions of Third Exemplary Embodiment
Also with the packaging container 1 according to the third exemplary embodiment having the structure described above, as with the first exemplary embodiment, a user may easily notice the presence of the handle portions 9 because the handle portions 9 are lifted when the upper cushion 13 is being removed. Also with the packaging container 1 according to the third exemplary embodiment, the handle portions 9 are easily raised above the upper surface of the object as compared with the case where the handle portions 9 are not lifted, and thereby the operability is improved.
Fourth Exemplary Embodiment
A fourth exemplary embodiment of the present invention will be described below. In the description of the fourth exemplary embodiment, the elements the same as those of the first exemplary embodiment will be denoted by the same numerals and detailed description of such elements will be omitted.
The fourth exemplary embodiment differs from the first exemplary embodiment in the following respects, but has the same structure as that of the first exemplary embodiment in other respects.
FIGS. 9A to 9C illustrate a packaging container according to a fourth exemplary embodiment, FIG. 9A illustrating a sectional view corresponding to FIG. 2B of the first exemplary embodiment, FIG. 9B corresponding to FIG. 5A of the first exemplary embodiment and illustrating a state in which an inner packing member is started to be taken out, and FIG. 9C corresponding to FIG. 5C of the first exemplary embodiment and illustrating a state in which the inner packing member has been taken out.
Referring to FIGS. 9A to 9C, in a packaging container 1 according to the fourth exemplary embodiment, the ends of the handle portions 9 of the plastic bag 6 are bonded to the lower surface of the bridge portion 13c of the upper cushion 13 via adhesive members 21. The material and amount of the adhesive members 21 are determined so that the adhesive members 21 may have a level of adhesion that allows the handle portions 9 to become detached from the adhesive members 21 and to drop off the upper cushion 13 when tension is applied to the handle portions 9 when the upper cushion 13 is being removed. That is, the handle portions 9 according to the fourth exemplary embodiment are removably supported by the upper cushion 13 via the adhesive members 21 that have a level of adhesion that allows the handle portions 9 to be removed from the adhesive members 21 when tension is applied to the handle portions 9.
Functions of Fourth Exemplary Embodiment
Also with the packaging container 1 according to the fourth exemplary embodiment having the structure described above, as with the first exemplary embodiment, a user may easily notice the presence of the handle portions 9, because the handle portions 9 are lifted as the upper cushion 13 moves when the upper cushion 13 is being removed as illustrated in FIGS. 9B and 9C. When the upper cushion 13 has been lifted and tension is applied to the handle portions 9, the handle portions 9 become detached from the adhesive members 21, and the ends of the handle portions 9 drop off the upper cushion 13. Then, as in the state illustrated in FIG. 5C, the handle portions 9 tend to lean against each other. Therefore, also with the fourth exemplary embodiment, as with the first exemplary embodiment, the handle portions 9 may be easily grasped and thereby the operability is improved.
Fifth Exemplary Embodiment
A fifth exemplary embodiment of the present invention will be described below. In the description of the fifth exemplary embodiment, the elements the same as those of the first exemplary embodiment will be denoted by the same numerals and detailed description of such elements will be omitted.
The fifth exemplary embodiment differs from the first exemplary embodiment in the following respects, but has the same structure as that of the first exemplary embodiment in other respects.
FIGS. 10A to 10C illustrate a packaging container according to a fifth exemplary embodiment, FIG. 10A illustrating a sectional view corresponding to FIG. 2B of the first exemplary embodiment, FIG. 10B corresponding to FIG. 5A of the first exemplary embodiment and illustrating a state in which lid portions are started to be opened, and FIG. 10C corresponding to FIG. 5C of the first exemplary embodiment and illustrating a state in which the lid portions have been opened.
Referring to FIGS. 10A to 10C, in a packaging container 1 according to the fifth exemplary embodiment, the cushioning member 11 is contained in the plastic bag 6. This is different from the first exemplary embodiment, in which the cushioning member 11 is mounted on the outside of the plastic bag 6. The handle portions 9 of the plastic bag 6 are removably supported by the inner surfaces of the lid portion 2c on the outer side via the adhesive members 21 as in the fourth exemplary embodiment. In the fifth exemplary embodiment, the handle portions 9 are attached to the lid portion 2c via the adhesive members 21 at positions separated by small distances from the center of the packaging container 1 in the front-back direction, because it is difficult to dispose the adhesive members 21 at the center, at which the lid portions 2c are connected to each other.
Functions of Fifth Exemplary Embodiment
With the packaging container 1 according to the fifth exemplary embodiment having the structure described above, the handle portions 9 are lifted and moved upward as the lid portion 2c moves when the lid portion 2c is being opened, and when the lid portion 2c has moved to the open position as illustrated in FIG. 10C, the handle portions 9 drop off the lid portion 2c. Therefore, also with the fifth exemplary embodiment, as with the first exemplary embodiment and other embodiments, a user may easily notice the presence of the handle portions 9 and easily grasp the handle portions 9, and thereby the operability is improved.
In the packaging container 1 according to the fifth exemplary embodiment, the cushioning member 11 is contained in the plastic bag 6, and when a user holds the handle portions 9 of the plastic bag 6 and lifts the plastic bag 6, the cushioning member 11 is taken out of the packaging container 1 together with the printer 4. When the user takes out the plastic bag 6 containing the printer 4 out of the outer box 2 and carries the plastic bag 6 to an installation position of the printer 4 by holding the handle portions 9, the plastic bag 6 may contact a desk, slip off a user's hand, or a shock may be applied to the plastic bag 6 if handled roughly. Even in such a case, breakage or the like of the printer 4 is reduced because the shock is absorbed by the cushioning member 11. In the fifth exemplary embodiment, the plastic bag 6 is in contact with the inner surface of the outer box 2. Therefore, it is expected that the friction is small as compared with the case where the cushioning member 11 is in contact with the inner surface of the outer box 2. That is, it is expected that the plastic bag 6 may be taken out more easily.
Modifications
The present invention is not limited to the exemplary embodiments described above, and may be modified in various ways within the scope of the present invention described in the claims. Modifications (H01) to (H014) of the exemplary embodiments of the present invention will be described below.
- (H01) In the exemplary embodiments described above, a printer, which is an example of an image forming apparatus, is used as an object. However, this is not limited thereto. The packaging container may be used to contain any goods including other image forming apparatuses such as a copier and a fax, consumables such as toner cartridges, and electronic appliances such as a personal computer and a liquid crystal display.
- (H02) In the exemplary embodiments described above, the number of handle portions 9 is two, because the plastic bag 6 may be handled easily in this case. However, this is not limited thereto. The number of handle portions may be three or more. For example, if an object has a large size, the handle portions 9 may be disposed at four positions in plan view. If the object has a triangular or pentagonal shape, the number of handle portions 9 may be three, five, or more. In such cases, the length of the handle portions 9 may be determined so that the three or more handle portions 9 may be held with a single hand. However, the length may be determined so that the handle portions 9 may be held with both hands or so that different numbers of handle portions 9 may be handled with the right hand and with the left hand.
- (H03) In the exemplary embodiments described above, the length L1 of the handle portion 9 satisfies L1≧La/2. However, this is not limited thereto. The length L1 may satisfy L1<La/2.
- (H04) In the exemplary embodiments described above, the positions of the connection portions 9b, at which the handle portions 9 are connected to the containing portion 7, are located above the corners 4d of the printer 4. However, this is not limited thereto. The connection portions 9b may be disposed below the corners.
- (H05) In the exemplary embodiments described above, the strength of the plastic bag 6 is increased by using the excess portions 7a. However, this is not limited thereto. For example, if the plastic bag 6 has a sufficient strength, the excess portions 7a may be disposed so as not to overlap the portions 7b extending along the outer surface.
- (H06) In the exemplary embodiments described above, the handle portions 9 are disposed on both sides in the longitudinal direction. However, this is not limited thereto. The handle portions 9 may be disposed on both sides in the transversal direction.
- (H07) In the third exemplary embodiment described above, the cushioning member 11 is (both the lower cushions 12 and the upper cushion 13 are) contained in the plastic bag 6. However, this is not limited thereto. For example, only the lower cushions 12 may be contained in the plastic bag 6, and the upper cushion 13 may be disposed outside the plastic bag 6 as in the first and second exemplary embodiments.
- (H08) In the exemplary embodiments described above, the structure of the cushioning member 11 is not limited to the examples described in the exemplary embodiments. In accordance with the shape of an object, any appropriate number of cushioning members having any appropriate shapes may be used. The upper cushion 13 is an integrated structure having the frame portion 13a. However, this is not limited thereto and may be modified in any appropriate way. For example, the upper cushion 13 may have a structure the same as those of the lower cushions 12 or a structure including a pair of right upper cushions connected to each other and a pair of left upper cushions connected to each other.
- (H09) In the exemplary embodiments described above, the shape, the position, and the number of the bridge portion 13c, which is an example of a supporting portion, are not limited to those described in the exemplary embodiments. As long as the bridge portion 13c is capable of supporting the handle portion 9, the bridge portion 13c may have any shape such as a protruding shape, a bar-like shape, or a hook-like shape. There may be two or more bridge portions 13c. The position of the bridge portion 13c may be changed in the left-right direction and in the front-back direction.
- (H010) In the exemplary embodiments described above, the upper cushion is used as an example of an inner packing member. However, this is not limited thereto. For example, the inner packing member may be a box or the like containing a manual or peripherals such as connection cables.
- (H011) In the fourth and fifth exemplary embodiments, the handle portions 9 are removably supported by the upper cushion 13 or the lid portions 2c via adhesive members. However, this is not limited thereto. Any structure that is capable of removably supporting the handle portions 9 may be used. For example, double-sided adhesive tape may be used. Alternatively, the handle portions 9 may be hooked to a hook-like member in such a way that the handle portions 9 may be unhooked when the upper cushion 13 or the like moves.
- (H012) In the fifth exemplary embodiment, the handle portions 9 are supported by the lid portion 2c on the outer side, which is an example of a closing portion. However, this is not limited thereto. The handle portions 9 may be supported by the lid portion 2c on the inner side. The first to third exemplary embodiments and the fourth and fifth exemplary embodiments may be used in combination, and the handle portions 9 may be removably supported by using adhesive members or the like in the configurations of the first to third exemplary embodiments.
- (H013) In the fourth and fifth exemplary embodiments, the handle portions 9 may be bonded to the upper cushion 13 or the like and the ends of the handle portions 9 may be joined to each other via an adhesive member, so that the handle portions 9 may easily lean against each other. Alternatively, in the first and second exemplary embodiments, the handle portions 9 may be bonded to each other via an adhesive member in such a way that the handle portions 9 are lifted in the joined state when the upper cushion 13 is being lifted, and when the upper cushion 13 is lifted further, the bridge portion 13c cuts the bonding to cause the handle portions 9 to easily lean against each other.
- (H014) In the fifth exemplary embodiment, the upper cushion 13 and the lower cushions 12 need not be contained in the plastic bag 6. In the first to fourth exemplary embodiments, the lower cushions 12 may be contained in the plastic bag 6, or the upper cushion 13 may be contained in the plastic bag 6 and the upper cushion 13 may be taken out first.
