Description

Technical Field

[0001] The present invention relates to a tape core for a tape dispenser. Background Art

[0002] Conventionally, a tape core is known that is wound around a tape and attached to a tape dispenser for use (for example, see Patent Document 1).

[0003] Recently, there have been tapes with a variety of patterns, designs, colors, etc., such as masking tapes. In order to be able to quickly use a plurality of tapes with a variety of patterns, it is necessary to prepare a plurality of tape cores and individually wind each tape around the tape core.

[0004] Yet, like this, the number of the tape cores of the belt is excessively increased and becomes the state of being easily dispersed, so management may become very complicated. Particularly, if the tape core is a relatively small tape core, it may also be lost during carrying.

[0044] Below, refer to Figures 1 to 17 An embodiment of the present invention will be described.

[0045] This embodiment is applied to a tape dispenser D capable of holding a masking tape as the tape T.

[0046] The tape dispenser D includes: a tape dispenser main body A; a replacement part B that holds the tape T and is supported so as to be rotatable relative to the tape dispenser main body A; and a tape pusher C that is supported so as to be movable relative to the tape dispenser main body A, that is, to be able to linearly advance and retreat. The tape pusher C constitutes a tip portion separation unit that separates the tip end st of the tape T from the cutting portion 5.

[0047] The tape dispenser D of the present embodiment is a relatively small-sized tape dispenser with a front-to-back dimension of approximately 3 cm.

[0048] Hereinafter, each structure of the tape dispenser D will be described in detail.

[0049] <<With dispenser body A>>

[0050] The tape dispenser main body A comprises: left and right side walls 1, 2; a replacement support shaft 3 which is arranged between the left and right side walls 1, 2 and serves as a tape body support portion; a retaining portion 4 which is arranged between the left and right side walls 1, 2 and temporarily adheres and retains the tape T pulled out from the tape body R; and a cutting portion 5 which is arranged between the left and right side walls 1, 2 and has a knife 51 which cuts the tape T pulled out from the tape body R.

[0051] Left and right side walls 1 and 2

[0052] The left and right side walls 1 and 2 form a pair and have substantially the same shape. The left and right side walls 1 and 2 are each formed in a substantially horizontal egg shape with the vertical dimension gradually becoming shorter toward the front.

[0053] The left and right side walls 1 and 2 each have a partially arcuate rear edge e1 that forms a partial arc in side view; an upper straight edge e2 that continues from the rear partially arcuate edge e1 and extends forward to form the upper edge; a lower straight edge e3 that continues from the rear partially arcuate edge e1 and extends forward to form the lower edge; and a partially arcuate front edge e4 that connects the front ends of the upper straight edge e2 and the lower straight edge e3 in side view. Furthermore, in each of the left and right side walls 1 and 2, the upper straight edge e2 and the lower straight edge e3 are formed to gradually approach each other from the rear side toward the front side.

[0054] The left side wall 1, such as Figure 5 As shown, the outer surface is provided with a plurality of recesses 11, which serve as engaging portions and form connecting portions S capable of connecting to the belt core M. In this embodiment, the recesses 11 are provided at six locations. The six recesses 11 are positioned approximately equidistantly from the axis of the replacement support shaft 3, surrounding the axis. Adjacent recesses 11 are arranged at equal intervals within the six recesses 11.

[0055] A plurality of anti-slip protrusions 12 , namely two protrusions 12 are provided on the rear end edge of the left side wall 1 , each protruding from one side and the other side, and capable of being caught by the user's fingers.

[0056] On the inner surface of the left side wall 1, in order from back to front, the replacement part support shaft 3, the holding portion 4, and the cutting portion 5 are respectively provided protruding toward the right side wall 2. An annular recessed portion 13 is formed around the replacement part support shaft 3 on the inner surface side of the left side wall 1, for arranging the left side plate m3 of the tape core M.

[0057] Furthermore, the recessed portion 13 accommodates a convex portion 21 provided protruding from the side plate m2 on the right side when the tape core M is reversed left-right and mounted on the tape dispenser body A.

[0058] The right side wall 2, such as Figure 4 As shown, a plurality of protrusions 21 are provided on the outer side of the rear portion, forming a connecting portion S that can be connected to the belt core M. In this embodiment, the protrusions 21 are provided at two locations. The protrusions 21 in the two locations are provided at approximately equal distances from the axis of the replacement support shaft 3. The protrusions 21 in the two locations are symmetrically arranged around the axis of the replacement support shaft 3.

[0059] On the inner surface of the side wall 2 on the right side, there are arranged in sequence from back to front: a cylindrical support shaft supporting member 22, which is inserted into the hollow part 31 of the replacement part support shaft 3 erected on the side wall 1 on the left side; a plate-shaped retaining part supporting member 23, which is inserted into the hollow part 41 of the retaining part 4 erected on the side wall 1 on the left side; and an interlocking recess not shown in the figure, which can be engaged with the interlocking protrusion 52 at the top end of the cutting part 5 erected on the side wall 1 on the left side.

[0060] When installing the replacement part B on the tape dispenser main body A, first, separate the left side wall 1 and the right side wall 2, and insert the replacement part support shaft 3 provided on the left side wall 1 into the shaft hole m11 of the replacement part B. Next, dock the left and right side walls 1 and 2 with each other, and engage the support shaft support member 22, the retaining portion support member 23, and the not-shown interlocking recess provided on the right side wall 2 with the hollow portion 31 of the replacement part support shaft 3, the hollow portion 41 of the retaining portion 4, and the interlocking protrusion 52 provided on the left side wall 1. The replacement part B is maintained in a state that can be used for the tape dispenser main body A. On the other hand, if the left and right side walls 1 and 2 are separated from each other, the replacement part B can be removed or replaced with another replacement part B.

[0061] <Replacement support shaft 3>

[0062] The replacement support shaft 3 extends in the left-right direction and has a cylindrical shape. The replacement support shaft 3 has a support shaft support member 22 erected on the right side wall 2 inserted into a hollow portion 31 inside.

[0063] The replacement support shaft 3 can rotatably support the replacement B that holds the belt body R formed by winding the belt T into a roll. Specifically, the replacement support shaft 3 is inserted into the shaft hole m11 formed in the cylindrical portion m1 of the replacement B and extending in the left-right direction.

[0064] <Holding unit 4>

[0065] The holding portion 4 extends in the left-right direction and is disposed forward of the replacement support shaft 3. The holding portion 4 is in the shape of a square cylinder, and a holding portion support member 23 erected on the right side wall 2 is inserted into the hollow portion 41 inside.

[0066] The retaining portion 4 has a tape adhesive portion 42 on its upper end surface to which a portion of the tape T pulled from the tape body R can be temporarily adhered. The tape adhesive portion 42 is formed of an inclined surface that gradually descends from the rear side toward the front side when viewed from the side. In addition, the tip of the blade 51 in the cutting portion 5 is located on an imaginary extension line of the tape adhesive portion 42.

[0067] The front surface of the retaining portion 4 is an upright surface. The back surface of the retaining portion 4 is a curved surface with the middle portion in the vertical direction recessed forward relative to the upper and lower ends so as not to interfere with the replacement part B supported by the replacement part support shaft 3. The lower surface of the retaining portion 4 is an inclined surface that gradually descends from the front toward the rear.

[0068] <Cutting section 5>

[0069] The cutting portion 5 extends in the left-right direction and has a knife 51 at its upper end for cutting the tape T pulled out of the tape body R. The cutting portion 5 is positioned forward of the retaining portion 4. The cutting portion 5 is in the shape of an upright plate. A fitting protrusion 52 is provided at the extended end of the cutting portion 5 extending from the left side wall 1 and is fitted into a fitting recess (not shown) formed in the right side wall 2.

[0070] On the back of the cutting portion 5, upper and lower locking recesses 53 and 54 are formed in a mountain shape at two locations. The upper and lower locking recesses 53 and 54 cooperate with the elastic engaging portion 62 with the pushing portion C to form the resistance portion U described below.

[0071] <<Replacement Part B>>

[0072] The replacement member B is composed of a tape core M and a tape body R in which a tape T is wound around the tape core M in a roll shape.

[0073] The tape core M holds the tape body R formed into a roll shape by winding the tape T. The tape core M is attached to the tape dispenser main body A for use.

[0074] The belt core M includes: a cylindrical portion m1, which is arranged in the center and extends in the left-right direction; left and right paired side plates m3, m2, which are arranged at the left and right end portions of the cylindrical portion m1; and a connecting portion S, which is arranged on the left and right side plates m3, m2 and can be connected to other belt cores M of the same shape.

[0075] As will be described in detail later, the tape core M of the present embodiment is configured to be connectable to another tape core M having the same shape via a connecting portion S.

[0076] <Cylindrical part m1>

[0077] The cylindrical portion m1 is cylindrical and extends horizontally. Specifically, the cylindrical portion m1 has an axial hole m11 for inserting the replacement support shaft 3. The tape core M is supported rotatably relative to the tape dispenser body A by inserting the replacement support shaft 3 provided on the tape dispenser body A through the axial hole m11 of the cylindrical portion m1.

[0078] <Left and right side panels m3, m2>

[0079] The left and right side plates m3 and m2 each have a substantially annular shape in a side view, extending in a flange shape from the end edge of the cylindrical portion m1.

[0080] <Connection S>

[0081] The connecting portion S provided on the tape core M is used to connect to other tape cores M having the same structure. In this embodiment, since the connecting portion S is provided on the left and right side plates m3 and m2 of the tape core M, other tape cores M having the same structure can be connected to the tape core M on the left and right sides.

[0082] In other words, if a plurality of replacement parts B are prepared in which the tape T is wound around the tape core M, the plurality of replacement parts B can be sequentially connected in a row in the lateral direction by the connecting portion S.

[0083] The connecting portion S is provided on each of the left and right side panels m3 and m2. More specifically, the connecting portion S is composed of a protrusion r1 provided on the right side panel m2, which is one side panel, and an engaging hole r2 provided on the left side panel m3, which is the other side panel, and which serves as an engaging portion and can be engaged with the protrusion r1.

[0084] The protrusion r1 of the right side plate m2 provided in the tape core M fits into the engagement hole r2 provided in the left side plate m3 of another tape core M having the same structure, thereby connecting the two tape cores M and M to each other.

[0085] The engagement hole r2 of the left side plate m3 of the tape core M is fitted onto the protrusion r1 of the right side plate m2 of another tape core M having the same structure, thereby connecting the two tape cores M and M to each other.

[0086] First, the convex portion r1 provided on the right side plate m2 will be described.

[0087] The protrusion r1 is cylindrical. It protrudes outward from the outer surface of the right side panel m2. The protrusion r1 is provided in two locations, namely, multiple locations. The two protrusions r1 are positioned approximately equidistant from the axis of the cylindrical portion m1. The two protrusions r1 are positioned approximately symmetrically around the axis of the cylindrical portion m1.

[0088] Next, the engagement hole r2 provided in the left side plate m3 will be described.

[0089] The engaging holes r2 are circular holes sized to fit over the cylindrical protrusion r1. They are through-holes extending horizontally. Multiple engaging holes r2 are provided at six locations. These six engaging holes r2 surround the axis of the cylindrical portion m1 and are positioned approximately equidistant from the axis. The six engaging holes r2 are spaced evenly apart.

[0090] In this embodiment, the number of engaging holes r2 provided on the left side plate m3 is set to be greater than the number of protrusions r1 provided on the right side plate m2. This arrangement of the protrusions r1 and engaging holes r2 of the tape core M facilitates the operation of connecting the protrusions r1 of the tape core M to the engaging holes r2 of another tape core M.

[0091] That is, the user can operate in such a way that the protrusions r1 at two locations engage with any of the engaging holes r2 at six locations, thereby connecting the belt core M with other belt cores M by easily docking the protrusions r1 and the engaging holes r2 (dock them with a rough feeling).

[0092] Furthermore, by making the number of projections r1 smaller than the number of engagement holes r2, the number of projections r1 that tend to be conspicuous in shape and detract from the design can be reduced, thereby contributing to ensuring a suitable appearance of the entire tape core M.

[0093] Furthermore, since mold adjustment for forming the projections r1 requires relatively much man-hours, making the number of projections r1 smaller than the number of engagement holes r2 contributes to a reduction in the man-hours required for mold adjustment.

[0094] In addition, if Figures 12-14 As shown, the connection portion S of the tape core M is configured to be connectable to the connection portions S (recess 11 or convex 21) of the left and right side walls 1 and 2 provided on the outer side of the tape dispenser D, namely, in the tape dispenser body A.

[0095] Moreover, if Figures 15-17 As shown, the connecting portion S (convex portion r1) of the tape core M is configured to be connectable to the connecting portion S (engaging hole k1) of the rotating plate K directly connected to the operating handle J provided on the tape rewinder E. A more specific structure of the tape rewinder E will be described in detail later.

[0096] <<With push-out section C>>

[0097] The tape pusher C is supported so as to be movable forward and backward relative to the tape dispenser body A. The tape pusher C is configured to be movable relative to the tape dispenser body A by a user's operation and to push out the tape T in a direction intersecting the direction in which the tape T extends.

[0098] The tape pusher C includes an upper portion 6 having a pusher head 61 formed at its upper end for contact with the adhesive surface nm of the tape T and extending in the vertical direction; and a lower portion 7 extending obliquely downward and rearward from the lower end of the upper portion 6. The tape pusher C, formed by the upper portion 6 and the lower portion 7, forms a "く" shape in a side view.

[0099] <Part 6>

[0100] The upper portion 6 is generally plate-shaped, extending horizontally and vertically. It includes an ejector head 61, located at its upper end and capable of contacting the tape T, and an elastic engaging portion 62, which is cantilevered, with its lower end free, to the right of the vertically intermediate portion when viewed from the front. The elastic engaging portion 62 has a locking protrusion 62a at its lower tip, which is capable of locking with the upper and lower locking recesses 53 and 54 in the cutting portion 5. The upper portion 6 is located within a vertically extending gap sk formed between the cutting portion 5 and the retaining portion 4, and is guided by this gap sk to allow for vertical movement.

[0101] The push-out head 61 has a forward-projecting movement restriction portion 61a formed below the upper end. When the tape push-out portion C is in the retracted position (Q), the movement restriction portion 61a engages with the upper portion of the cutting portion 5 to restrict movement of the tape push-out portion C below the retracted position (Q).

[0102] The elastic engaging portion 62 constitutes a resistance portion U that prevents the tape pusher C from moving to the push-out position (P) or the retreat position (Q) until a predetermined pressing force is applied. In other words, the elastic engaging portion 62 selectively engages with either the upper locking recess 53 or the lower locking recess 54 provided on the cutting portion 5, thereby controlling the tape pusher C to be locked in the push-out position (P) or the retreat position (Q).

[0103] More specifically, when the tape pusher C is in the push-out position (P), the elastic locking projection 62a of the elastic locking portion 62 elastically engages with the upper locking recess 53 in the cutting portion 5, thereby maintaining the tape pusher C in the push-out position (P). Furthermore, when the tape pusher C is in the retracted position (Q), the elastic locking projection 62a of the elastic locking portion 62 engages with the lower locking recess 54 in the cutting portion 5, thereby maintaining the tape pusher C in the retracted position (Q).

[0104] <Part 7>

[0105] The lower portion 7 is in the shape of a plate that integrally extends obliquely downward and rearward from the lower end portion of the upper portion 6 .

[0106] The lower portion 7 of the tape pusher C has a pressed portion 71 located below the retaining portion 4 in the tape dispenser body A and capable of receiving an upward pressing operation by the user. Specifically, when the pressed portion 71 of the tape pusher C located in the retracted position (Q) is pressed upward by the user's finger, the tape pusher C overcomes the resistance generated by the resistance portion U and moves to the pusher position (P).

[0107] During this process, the tape pushing portion C pushes the tape T pulled out from the tape body R upward from the bottom. When the tape pushing portion C reaches the pushing position (P), the top end st of the tape T is removed from the cutting portion 5 to the extent that the user's fingertips can enter, making it easy for the user to pinch the top end st of the tape T with their fingers.

[0108] The tape pusher C is configured to be movable between a push-out position (P) located on the belt track kd between the tape body R and the cutting portion 5 and a retracted position (Q) retracted from the belt track kd.

[0109] In this embodiment, the tape pusher C is provided between the cutting portion 5 and the holding portion 4. In other words, the tape pusher C is held by the cutting portion 5 and the holding portion 4 in cooperation with each other so as to be movable up and down.

[0110] While moving from the retreat position (Q) to the push-out position (P), the tape push-out portion C can come into contact with the lower surface of the tape T, that is, the adhesive surface nm side, and push the tape T upward.

[0111] Furthermore, in this embodiment, the tape pusher C, located at the push-out position (P), is configured to automatically move toward the retracted position (Q) in response to the user's operation to cut the tape T. Specifically, when the user grasps the tip end st of the tape T and pulls the tape T outward, i.e., forward, by a certain length, and then lowers the tape T while tightening it to allow the knife 51 to cut it, the tape pusher C is pushed down by the tape T and can move toward the retracted position (Q).

[0112] A resistance portion U is provided between the tape pusher C located at the push-out position (P) and the tape dispenser body A. Therefore, when the resistance portion U is subjected to a predetermined downward pressing force accompanying the aforementioned cutting operation (operation for lowering the tape T) performed by the user, the tape pusher C can overcome the resistance generated by the resistance portion U and move toward the retracted position (Q).

[0113] <<With rewinder E>>

[0114] A tape rewinder E having a structure capable of connecting the tape core M constituting the replacement B via a connecting portion S will be described.

[0115] like Figures 15-17 As shown, the tape rewinder E can rewind the tape TL pulled from the finished tape body L onto the tape core M. The tape rewinder E rotatably holds the finished tape body L, formed by winding the tape TL into a roll. Furthermore, the tape rewinder E is provided with an operating handle J that is rotated by the user. A rotating plate K is provided at the base of the operating handle J, which is rotatable integrally with the operating handle J. The tape rewinder E can also attach the tape core M of the tape dispenser D to the rotating plate K.

[0116] That is, the tape rewinder E can rewind the tape TL pulled out from the manufactured tape body L onto the tape core M connected to the rotating plate K by rotating the operating handle J. After pulling the tape TL out of the manufactured tape body L, the tape rewinder E rewinds the tape TL onto the cylindrical portion m1 of the tape core M, thereby separating a portion of the tape TL from the manufactured tape body L toward the tape core M.

[0117] The belt rewinder E comprises: a base body F, which can adopt a holding posture (a) for holding the belt core M in a non-detachable manner and a loadable posture (b) for loading and unloading the belt core M relative to the rotating plate K; a belt body holding portion G, which can support the prepared belt body L so as to be rotatable relative to the base body F; an operating handle J, which is supported so as to be rotatable relative to the base body F; a rotating plate K, which rotates integrally with the operating handle J and is provided with a connecting portion S to which the belt core M can be connected; and a belt core M, which is configured to be loadable and unloadable relative to the rotating plate K.

[0118] The rotating plate K has engaging holes k1, which serve as connecting portions, at positions corresponding to the two protrusions r1 provided on the belt core M. These two protrusions r1 can be externally engaged. With the base F in the detachable position (b), the belt core M is attached to the rotating plate K via the connecting portions. Afterwards, the second base member f2, which is in the deployed position (d), is changed to the use position (c). Thus, the base F in the retaining position (a) can retain the belt core M so that it can rotate integrally with the operating handle J.

[0119] The base F comprises: a first base member f1 having a rising wall f11 on one side; a second base member f2 having a rising wall f21 on the other side and being configured to be able to adopt a usage posture (c) in which the rising wall f21 on the other side is roughly parallel to the first base member f1 and a deployment posture (d) in which the rising wall f21 on the other side is roughly parallel to a loading surface such as a top plate; and a locking mechanism N, which can lock the second member in the usage posture (c).

[0120] As described above, the tape core M according to this embodiment is wound around the tape T and attached to the tape dispenser D for use. Furthermore, the tape core M can be connected to other tape cores M having the same shape via the connecting portion S. Therefore, it is possible to provide a tape core M configured so that the plurality of tape cores M are less likely to become dispersed.

[0121] That is, even if a plurality of tape cores M are prepared and each tape T is independently wound around the tape cores M, the tape cores M can be connected to each other using the connecting portion S for tape T having a variety of patterns, designs, colors, etc.

[0122] Therefore, even if the number of tape cores M holding the tape T increases, management is less likely to become complicated. In other words, the user can quickly select the tape T he wants to use from the connected plurality of tape cores M and insert it into the tape dispenser D for use.

[0123] Furthermore, as in the present embodiment, even with a relatively small tape core M, it is preferably suppressed from being lost while being carried.

[0124] In addition, by connecting a plurality of tape cores M, it is possible to gather tapes T with a variety of patterns, designs, colors, etc. into a regularly arranged state. Figure 14 As shown in the example of , even when not in use, it can function as a decoration that easily stays in the viewer's sight and is easy to feel beautiful.

[0125] The belt core M includes a pair of left and right side plates m3 and m2 , and the connecting portion S is provided on each of the side plates m3 and m2 .

[0126] Therefore, it is possible to connect not only another tape core M having the same shape to the left side plate 3 m of the tape core M but also another tape core M having the same shape to the right side plate m2 .

[0127] The connecting portion S includes a protrusion r1 provided on the right side plate m2 as one side plate, and an engaging hole r2 as an engaging portion provided on the left side plate m3 as the other side plate and capable of being engaged with the protrusion r1 .

[0128] Therefore, by fitting the convex portion r1 of the tape core M into the engaging hole r2 of another tape core M, or fitting the engaging hole r2 of the tape core M into the convex portion r1 of another tape core M, the two tape cores M can be appropriately connected to each other.

[0129] The number of engagement holes r2 as engagement portions provided on the left side plate m3 as the other side plate is set to be greater than the number of projections r1 provided on the right side plate m2 as one side plate.

[0130] Therefore, the operation for connecting the protrusion r1 of the tape core M to the engagement hole r2 of another tape core M can be performed relatively easily.

[0131] In this embodiment, the user can operate so that the two protrusions r1 fit into any of the six engaging holes r2. Therefore, the user can connect the tape core M to another tape core M by easily aligning the protrusions r1 with the engaging holes r2 (approximately aligning them).

[0132] Furthermore, by making the number of projections r1 smaller than the number of engagement holes r2, the number of projections r1 that tend to be conspicuous in shape and may impair the appearance can be reduced, thereby contributing to ensuring a suitable appearance of the tape core M as a whole.

[0133] Furthermore, during the manufacturing process of the tape core M, mold adjustment for forming the projections r1 requires considerable man-hours. Therefore, reducing the number of projections r1 relative to the number of engagement holes r2 contributes to a reduction in the man-hours required for mold adjustment.

[0134] The connecting portion S is configured to be connectable also to the outer surfaces of the left and right side walls 1 and 2 , which are outer portions of the tape dispenser D.

[0135] Therefore, it is possible to connect a tape core M that is not built into the tape dispenser D to one or both of the left and right side walls 1 and 2. Therefore, the user can select a tape core M wound with the tape T that he wants to use from the plurality of tape cores M connected to the tape dispenser D, and quickly install it in the tape dispenser D for use.

[0136] Furthermore, since the unused tape cores M can be connected to the tape dispenser D directly or indirectly via the tape cores M, not only can the tape cores M be appropriately prevented from being scattered, but also the tape cores M can be appropriately prevented from being lost.

[0137] The connecting portion S of the tape core M is configured to be connectable to a rotating plate K directly connected to an operating handle J provided on the tape rewinder E. The tape rewinder E can rewind the tape LT, which has been pulled out from a finished tape body L wound into a roll, onto the tape core M connected to the rotating plate K by rotating the operating handle J.

[0138] Therefore, the tape core M can be stably attached to the tape rewinder E via the connecting portion S for use. In other words, the tape core M is a member that can be used to rewind the tape TL in order to subdivide the tape LT from the manufactured tape body L. For example, by preparing a plurality of tape cores M, sequentially attaching each tape core M to the rotating plate K, and operating the tape rewinder E, the tape TL formed into the manufactured tape body L can be subdivided into a plurality of tape cores M. Since the tape core M is connected to the rotating plate K via the connecting portion S, the tape TL subdivided from the manufactured tape body L can be appropriately wound around the tape cores M.

[0139] In addition, the present invention is not limited to the embodiments described in detail above.

[0140] The type of tape can be applied to various types and is not limited to masking tape.

[0141] The tape dispenser having a built-in tape core is not limited to the tape dispenser shown in the above embodiment.

[0142] The specific form of the connecting portion is not limited to the form consisting of the protrusion and the engaging hole as described above. For example, the connecting portion can be a connecting portion that can connect the belt core to another belt core of the same shape via a magnet, or a connecting portion that can be connected via a surface fastener (velcro).

[0143] The left and right side panels are not necessarily formed in an annular shape (ring shape), and may be polygonal side panels, elliptical side panels, or asymmetrical side panels.

[0144] The engaging portion that can be engaged with the convex portion may be a concave portion limited to the engaging hole.

[0145] In the above embodiment, the number of engaging portions provided on the other side panel is set to be greater than the number of protrusions provided on one side panel, but the present invention is not limited to this configuration. For example, the number of engaging portions and protrusions may be set to be the same. Alternatively, for example, the number of engaging portions provided on the other side panel may be set to be less than the number of protrusions provided on one side panel.

[0146] Furthermore, the specific configuration of each component is not limited to the above-described embodiment, and various modifications are possible without departing from the spirit of the present invention.
