When the housing 2 is supplied to the engaging device 10, the supporting device 12 is in a closed form. When the support device 12 is in the closed configuration, the first support member 18, the second support member 19 and the third support member 44 are connected to the first engagement device 25, The relative arrangement of the device 35 and the third engagement device 45 is arranged so as to be identical to the rear panel 2PE, the left panel 2PC and the front panel 2PA of the housing 2 which is folded flat . When the housing 2 is supplied to the engaging device 10, the pin 27 provided on the first engaging device 25 is stuck on the upper face of the rear upper flap 2UC of the housing 2, The pin 27 provided on the fitting device 25 is engaged with the rear upper flap 2UC. The pin 27 provided on the second engaging device 35 is engaged with the left upper flap 2UB and the pin 27 provided on the third engaging device 45 27 are coupled to the front upper flap 2UA. After the pin 27 is inserted into the upper flap 2U the injector plate 8 is lowered from the feeding position to the initial position and the housing 2 is moved to the first engaging device 25 and the second engaging device 35 And the third engaging device 45, and is left in the engaging device 10.

In this embodiment, the distance (X in Fig. 9) between the folding line between the rear panel 2PE and the left rear panel 2PD and the point Q in the left-right direction when the supporting device 12 is in the closed configuration, And the distance (Y in Fig. 9) between the folding line between the rear panel 2PE and the left rear panel 2PD and the front-rear direction of the point Q is larger than the distance (Z in Fig. 10) of the left panel 2PC with respect to the left-right direction (Z in Fig. 10) of the left panel 2PE with respect to the left-right panel 2PE, the housing 2 has the first engaging device 25, the second engaging device 35, The second supporting member 19, and the third supporting member 44. The first supporting member 18, the second supporting member 19,

When the housing 2 is supplied to the engaging device 10, the supporting device 12 is displaced from the closed form to the open form. The rear upper flap 2UC is engaged with the first engagement device 25 while the upper left flap 2UB is engaged with the second engagement device 35 , And the front upper flap 2UA is engaged with the third engaging device 45. As shown in Fig. The folding line between the trunk portion 2P and the upper flap 2U is difficult to collapse so that the rear panel 2PE directly connected to the rear upper flap 2UC moves together with the first engaging device 25 The left panel 2PC directly connected to the left upper flap 2UB moves together with the second engagement device 35 and the front panel 2PA directly connected to the front upper flap 2UA 3 engage with the engagement device 45.

The distance between the folding line between the rear panel 2PE and the left rear panel 2PD in the left and right direction of the point Q and the distance between the folding line and the front and rear direction of the point Q Since the difference in distance between the left panel 2PC and the rear panel 2PE of the housing 2 in the opened state is the same as the distance in the left and right direction of the left panel 2PC with respect to the rear panel 2PE, 1 relative to the left-right direction of the second engagement device 35 with respect to the first engagement device 25 by opening the support member 18 and the second support member 19 at an angle of about 90 degrees, Becomes the same as the relative position with respect to the left-right direction of the left panel 2PC with respect to the rear panel 2PE of the housing 2 in the opened state. The left panel 2PC is connected to the rear panel 2PE by the left rear panel 2PD and the first engagement device 25 is fixed to the first support member 18. Therefore, Is pulled backward by the rear panel 2PE. Since the second engagement device 35 is slidably supported by the second support member 19 in the front and rear direction in the extending direction thereof, by the force from the rear panel 2PE caught by the left panel 2PC The second engaging device 35 moves along the second supporting member 19 and the relative position of the second engaging device 35 with respect to the first engaging device 25 in the front- Rear direction of the left panel 2PC relative to the rear panel 2PE of the housing 2 as shown in Fig. The relative position of the second engaging device 35 relative to the first engaging device 25 is such that the relative position of the second engaging device 35 with respect to the first engaging device 25 is substantially the same as the relative position of the second engaging device 35 with respect to the rear panel Becomes equal to the relative position of the left panel (2PC) with respect to the left panel (2PE). The rear panel 2PE and the left panel 2PC form an angle of approximately 90 degrees with respect to each other and the left rear panel 2PD forms an angle of approximately 90 degrees with respect to the rear panel 2PE and the left panel 2PC, As shown in Fig.

When the support device 12 is in the open configuration, the second support member 19 is opened to form an angle of about 90 degrees with respect to the first support member 18. [ The third engaging device main body 46 is connected to the distal end side of the second engaging device main body 36 through the connection port 47 so that the third supporting member 44 is rotated by the centrifugal force, (19). The third support member 44 is pushed forward, and the third frame 43 is moved forward. When the support device 12 is in the open configuration, the third support member 44 is disposed at a predetermined distance in front of the first support member 18. The third engaging device body 46 is disposed approximately parallel to the first engaging device body 26 and is disposed forward of the second engaging device body 36 to the second engaging device body 36 ) At an angle of about 90 degrees.

The third engaging device main body 46 is connected to the distal end of the second engaging device main body 36 through a connection port 47 and the third engaging device main body 46 is connected to the third supporting member 44 As shown in Fig. Therefore, the third support member 44 also moves leftward as the second engaging device main body 36 moves. The third support member 44 moves to the left along the third frame 43 until it comes into contact with the opening stopper member 48. [ The distance between the left panel 2PC engaged with the second engaging device 35 and the left end of the left end of the front panel 2PA engaged with the third engaging device 45, The position of the opening stopper member 48 is determined so as to be equal to the distance in the left-right direction of the left panel 2PC with respect to the rear panel 2PE of the housing 2 in the opened state. Since the rotation angle of the connection port 47 with respect to the second engaging device main body 36 is regulated by the connection port stopper member 47S in this embodiment, the movement of the third engaging device 45 to the right Is regulated. The relative position of the third engaging device 45 with respect to the left and right direction relative to the first engaging device 25 is determined by the relative position of the third engaging device 45 with respect to the first engaging device 25 in the opened state of the housing 2 Is equal to the relative position in the lateral direction of the front panel 2PA relative to the rear panel 2PE.

The relative position of the third engagement device 45 with respect to the first engagement device 25 with respect to the left and right direction is determined by the relative position of the third engagement device 45 with respect to the left and right direction of the front panel 2PA with respect to the rear panel 2PE of the housing 2, As shown in FIG. Therefore, the left end of the front panel 2PA is located on a straight line extending back and forth beyond the left end of the rear panel 2PE. On the other hand, the front panel 2PA is connected to the left front panel 2PB, and the left front panel 2PB is connected to the left panel 2PC. Therefore, the left end of the front panel 2PA is centered on the front end of the left panel 2PC by the left panel 2PC, and the circumferential surface with the radius of the left front panel 2PB shown in Fig. . Therefore, the left end of the front panel 2PA moves to the intersection position of the straight line and the circle (R in Fig. 10). Further, since the third engaging device body 46 is displaced with its rearwardly facing surface, the front panel 2PA is arranged substantially parallel to the rear panel 2PE. Therefore, the relative position of the third engagement device 45 with respect to the first engagement device 25 is the same as the relative position of the front panel 2PA with respect to the rear panel 2PE of the housing 2 in the opened state It becomes. The rear panel 2PE and the front panel 2PA are positioned parallel to each other and the front panel 2PA is disposed at an angle of approximately 90 degrees with respect to the left panel 2PC when the support device 12 is in the open state . At the same time, the left front panel 2PB is disposed obliquely with respect to the front panel 2PA and the left panel 2PC. The distance between the rear panel 2PE and the front panel 2PA is larger than the width of the left rear panel 2PD and the width of the left panel 2PC and the width of the left front panel 2PB when the support device 12 is in the open form. The first supporting member 18 and the third supporting member 44 are disposed at positions that are smaller than the sum of the widths of the first supporting member 18 and the third supporting member 44. [

A second opening stopper member 99 is provided on the rail of the first frame 41 and the relative position of the third engaging device 45 with respect to the first engaging device 25 in the front- The forward movement of the third frame 43 may be restricted so as to be the same as the relative position of the front panel 2PA relative to the rear panel 2PE of the housing 2.

Since the left rear panel 2PD is inclined with respect to the rear panel 2PE and the left panel 2PC and the left front panel 2PB is inclined with respect to the front panel 2PA and the left panel 2PC, Is twist-deformed and the folding line between the right panel 2PG and the right front panel 2PH and the folding line between the right panel 2PG and the right rear panel 2PF are bent. By folding these folding lines, the trunk portion 2P is deformed into an octagonal shape. The upper flap 2U and the lower flap 2L are arranged so as to extend upward and downward, respectively, according to the arrangement of the panels directly connected to each other, and the enclosure is in the opened state.

When the housing 2 is delivered to the folding device 50, the supporting device 12 is displaced in a closed form and the first, second and third supporting members 18,19 and 44 And returned to the initial position. Since the housing 2 and the second engaging device 35 are out of engagement with each other when the housing 2 is delivered to the bending device 50, 35 are returned to the initial position with respect to the second support member 19, and the loading device 10 returns to the initial state.
