The present invention relates to a container container made of a sheet-like body.

Japanese Patent No. 3871692 JP 2007-62827 A

Conventionally, a paper container formed by folding and gluing a piece of paper has been widely used. And the paper box which can close an opening part by the said cover after opening by providing the cover integrally formed with the container main body is used as containers, such as a powder detergent.
As this container, in order to securely close the opening with the lid after opening, the lid is fixed in a state where the opening is closed after opening, as seen in Patent Document 1 and Patent Document 2 above. There has been proposed one having means to do this.

FIG. 10 shows the state of the container of Patent Document 1 before opening, FIG. 11 shows the state before opening, FIG. 12 shows the state where the bent piece 95 is bent after opening, and FIG. 12 shows the state where the opening of the opening container is closed. This is shown in FIG.
As can be seen from FIGS. 10 and 11, this container is superposed on the container main body 1 having an opening 83 on the upper surface, and the upper surface 31 and the front surface 41 of the container main body 1, and a part thereof is bonded. The covering portion 100 includes a remaining portion 21 that is bonded to the container main body portion 1 and a separation portion 11 that is separated from the remaining portion 21 to form an opening 83. The separation unit 11 includes a separation unit main body 103 and a bent piece 95 that are separated by a crease line 98. Before opening, as shown in FIG. 10, the bent piece 95 is stretched and integrated with the remaining portion 21. Reference numeral 107 denotes a locked portion bonded to the front surface 41 of the container body. This locked portion 107 is connected to the separation portion 11 before opening by a separation line appearing in a rectangle in the drawing.

As shown in FIG. 11, the separation part 11 is separated from the remaining part 21 leaving the base end, whereby the container is opened. The folded piece 95 is separated from the remaining portion 21 as a part of the separating portion 11 by opening.
As shown in FIG. 12, the bent piece 95 separated by opening is folded from the crease line 98 and overlapped with the separation portion main body 103. The bent piece 95 includes insertion portions 96 and 96 that protrude from the separation portion main body 103 in a state of being overlapped in this manner. The locked portion 107 is separated from the separation portion by the rectangular separation line when opened, and remains on the front surface 41 of the container body. As a result, the separation portion 11 is formed with a rectangular window portion 108 punched from the front surface to the back surface. Further, the tip of the folded piece 95 that is folded back serves as a locking portion 97.

The front face 41 and the remaining part 21 of the container main body constitute an inserted part, and when the container is closed after opening, as shown in FIG. Plugged in.
By inserting the insertion portions 96, 96 into the inserted portion, the locked portion 107 comes into contact and comes into contact with the locking portion 97 to prevent retreat. That is, the locking portion 97 is locked to the locked portion 107, and the insertion portions 96, 96 are prevented from coming out upward from the insertion portion.

As described above, in the container supplier, after the consumer separates from the separation part by opening as described above, the folding piece 95 is folded at the crease line 98, and the locking part becomes the locked part. The use of the container in a locked manner is intended.
However, for many consumers who purchased the products packed in the container, the trend at the time of using the products was examined. When the container was closed after opening the container, the folded piece 95 shown in FIG. 11 was not folded. It turned out that the insertion parts 96 and 96 are inserted and used for said insertion part in the state extended.
This is because it is troublesome to read the handling instructions attached to the container or to bend it one by one and place the locking portion at the correct position.

However, as described above, if the bent piece 95 is bent and the locking portion 97 is not disposed at the correct position locked to the locked portion 107, the insertion portions 96, 96 can be easily removed from the plugged portion. The separation part 11 covering the opening 83 opens upward. Moreover, the insertion parts 96 and 96 themselves also pass through the insertion part, and it is difficult to put them in the proper state.

In addition, in the above conventional container, as shown in FIG. 11, opening opens a window portion 108 penetrating the front and back, reducing the strength of the separating portion that functions as a lid after opening, and weakening the portion. Resulting in. Moreover, moisture permeates into the inside of the separation part from the cross section of the window part 108, and also in this respect, the strength of the paper is lowered and weakened.

The present invention is intended to provide a container capable of reliably closing the opening after opening without making such a troublesome work for the consumer.
Moreover, this invention aims at provision of the container which can perform said closure reliably, without forming the penetration part which weakens intensity | strength in the isolation | separation part which functions as a lid | cover by opening.

The upper covering portion 11 is overlaid on the surface of the upper surface portion 31 and is bonded almost entirely or partially, and the front covering portion 21 is overlaid on the surface of the front surface portion 41 and is partially bonded. These adhesion points will be described later.

In the container of this example, a ruled line 52 that is a concave line is formed on the lower surface portion 51 and a part of the rear surface portion 61 as shown in FIG. When discarding the container, it is possible to fold the container in a compact manner by folding the portions 51 and 41 at the portion where the ruled line 52 is formed. The formation of the ruled line 52 is not essential and may be omitted. Further, the form of the ruled line 52 is not limited to that shown in the figure, and various forms such as a perforation are possible as long as the container can be easily folded.

Next, closing of the open end (FIGS. 2 and 3) by the flaps 71 to 78 will be described. Here, the open end on the left side of the container is between the upper surface portion 31 and the left upper surface flap 71, between the front surface portion 41 and the left front surface flap 73, between the lower surface portion 51 and the left lower surface flap 75, and the rear surface portion 61. And the crease line n existing between the left rear flap 77 and the left rear flap 77, respectively. Moreover, the opening end on the right side of the container is between the upper surface portion 31 and the right upper surface flap 72, between the front surface portion 41 and the right front surface flap 74, between the lower surface portion 51 and the right lower surface flap 76, and the rear surface portion 61. A crease line n existing between the right rear surface flap 78 and the right rear surface flap 78 is used as an edge. That is, each of the flaps 71 to 78 can be expressed as a sheet-like body provided on the edge of the opening end.

Here, the left lower surface flap 75 and the right lower surface flap 76 will be described. Since the left lower surface flap 75 is symmetrical with the right lower surface flap 76, the right lower surface flap 76 will be described as a representative. The right lower surface flap 76 is formed with a lower portion 76a that overlaps the right rear surface flap 78 and a higher portion 76b that is not. The low-order part 76a and the high-order part 76b are formed by pressing, and a detour part 76c that is a step exists between the low-order part 76a and the high-order part 76b.

As shown in FIG. 1 and the like, the bypass portion 76c is formed as a bent line segment, and is orthogonal to the crease line n (nc) between the lower surface portion 51 and the right lower surface flap 76. The first portion 76c1 that appears on the surface of the right lower surface flap 76 as a line segment, and the first portion 76c1 that is continuous with the first portion 76c1, appears on the surface of the right lower surface flap 76 as a line segment that is parallel to the crease line n (nc). The second portion 76c2 and the third portion 76c3 continuous to the second portion 76c2 and appearing on the surface of the right lower surface flap 76 as a line segment parallel to the first portion 76c1.

The left lower surface flap 75 and the right lower surface flap 76 are located at the lower part of the opening end on the side of the container as shown in FIG. A left upper surface flap 71 and a right upper surface flap 72 are provided. Since the left upper surface flap 71 is symmetrical with the right upper surface flap 72, the right upper surface flap 72 will be described as a representative.

The surface of the right upper surface flap 72 includes a low-order part 72a, a middle-order part 72b, and a high-order part 72c. The middle part 72b is lower than the high part 72c, and the low part 72a is lower than the middle part 72b. The low-order part 72a is formed by superimposing a right overlapping flap 72z on the surface, and the level difference from the middle-order part 72b is eliminated by the superposition. The surface of the right overlapping flap 72z and the surface of the middle portion 72b that are overlaid on the surface of the lower portion 72a are overlapped with the right rear surface flap 78, and the step with the higher portion 72c is eliminated by this overlapping. A first detour portion 72d forming a step is provided between the lower portion 72a and the middle portion 72b, and a second detour portion 72e forming a step is provided between the middle portion 72b and the high portion 72c. Yes.

Both the detour portions 72d and 72e are formed as bent line segments, like the detour portion 76c of the right lower surface flap 76 described above, and a first portion orthogonal to the crease line n (na), and a first portion And a second portion that is parallel to the crease line n (nb) and a third portion that is continuous to the second portion and parallel to the crease line n (na).

Next, the left rear surface flap 77 and the right rear surface flap 78 superimposed on the left lower surface flap 75 and the right lower surface flap 76 will be described. Since the left rear surface flap 77 has a symmetrical relationship with the right rear surface flap 78, the right rear surface flap 78 will be described.
An edge of the right rear surface flap 78 facing the crease line n (nd) is an overlapping edge 78a. The overlapping side 78a is parallel to the crease line n (nd) and parallel to the crease line n (nd) and the first side 78a1 located relatively close to the crease line n. And is orthogonal to the third side 78a3 and the first side 78a1 and the third side 78a3 that are relatively far from the crease line n (nd), and A second side 78a2 connecting the side 78a1 and the third side 78a3 is provided. In this example, the corners of the right rear surface flap 78 are cut out by the first side 78a1 and the second side 78a2 of the overlapping side 78a.

The overlapping side 78 a is formed in the bypass portion 76 c formed in the right lower surface flap 76 and the right upper surface flap 72 when the right rear surface flap 78 is superimposed on the right lower surface flap 76 and the right upper surface flap 72. The second bypass portion 72e is matched with each other. Specifically, among the overlapping sides 78a, the first side 78a1 and the first portion 76c1 of the detour portion 76c similarly match the first side 78a1 and the first portion of the second detour portion 72e, and the overlapping side 78a. Among the second side 78a2 and the second portion 76c2 of the bypass portion 76c, the second side 78a2 and the second portion of the second bypass portion coincide with each other, and the third side 78a3 and the bypass portion of the overlapping side 78a. Similarly, the third portion 76c3 of 76c coincides with the third side 78a3 and the third portion of the second bypass portion 72e.
Note that the “match” may be one in which a gap is maintained between the overlapping side 78a, the detour portion 76c, and the second detour portion 72e, or may be in close contact with no gap. However, it is not preferable that the right rear surface wrap 78 ride on the upper portion 72c, 76b of the upper surface flap 72 or the right lower surface flap 76 beyond this closely contacted state, because there is a possibility of leakage of stored items.
The front edge of the right overlapping flap 72z also has a shape corresponding to the first bypass portion 72d of the right upper surface flap 72.

Here, what has been described above is shown together with FIGS. First, the sheet is fold-folded as described above at the first crease line m1, the second crease line m2, and the third crease line m3 in FIG. As a result, the state shown in FIG. 2 is obtained.
From the state shown in FIG. 2, the left and right upper surface flaps 71 and 72 are folded at the crease lines na and na, the left and right lower surface flaps 75 and 76 are folded at the crease lines nc and nc, and further overlapped at the crease lines ne and ne. The sheets are brought into the state shown in FIG. 3 by folding the mating flaps 72z and 72z.
From the state shown in FIG. 3, the covering portion 10b is folded toward the upper surface portion 31 at the fourth fold line m4. At this time, the overlapping flaps 72z and 72z are bonded to the lower portions of the left and right upper surface flaps 71 and 72, respectively. Then, by folding the left and right rear flaps 77 and 78 along the crease lines nd and nd, the overlapping flaps 72z and 72z bonded to the upper surface flaps 71 and 72 and the middle portion of the upper surface flaps 71 and 72 are moved to the left and right sides. The rear flaps 77 and 78 are overlapped and bonded.
After the left and right rear flaps 77 and 78 are overlapped and bonded, the left and right front flaps 73 and 74 are folded at the crease lines nb and nb so that the left and right front flaps 73 and 74 are connected to the left and right rear flaps 77 and 78. The upper surface flaps 71 and 72 on the front surface and the left and right upper flaps 71 and 72 are bonded to each other in a superimposed manner (see FIG. 4A). In the above description, only the left and right front flaps 73 and 74 are bonded, and the overlapping flaps 72z and 72z and the left and right rear flaps 77 and 78 are not glued.

In this way, when the flaps 72, 74, 76, 78 are overlapped and the opening end is closed, the left and right lower surface flaps 75, 76 are not affected even if there is a slight shift in the overlap position of the flaps. And the second overlapping portion of the left and right upper and lower flaps 71 and 72 and the second side of the overlapping side of the left and right rear surface flaps 77 and 78, and the left and right overlapping flaps 71z and 72z. By the part conceived of the second side and the second part of the detour part, it is blocked and the content of the powder can be prevented from leaking outside.

Here, in the present invention, the bypass portion is formed in each of the flaps by pressing, and is due to the overlapping of the overlapping flaps 71z and 72z. It has the advantage that leakage of things can be prevented.

In this example, it is assumed that the first side 78a1, the second side 78a2, and the third side 78a3 are formed on the overlapping side 78a by cutting out the corner portion of the right rear side flap 78. The right lower surface flap 76 and the right upper surface flap 72 to be overlaid are formed with detour portions that coincide with the overlap side 78a. The shapes of the overlap sides 78a and the detour portions are the same as those in this example. It is not limited, and it may be anything that appears as a bent or curved line segment.
Other examples of the shape of the right rear flap 78 corner include a shape in which the corner is cut out in a circle, a shape in which a square cut is formed in the end, a shape in which a triangular cut is formed in the end, Examples thereof include a semicircular cut formed on the side, a straight side repeatedly formed, and a curved side repeatedly formed in a wavy line. The same applies to the left rear flap 77, the left upper flap 71 and the left lower flap 75.

Next, other parts of the container will be described. As shown in FIG. 1, a separation line (first separation line) for forming an opening is formed on the upper surface portion 31 and the front surface portion 41. The separation line may be any line that can be separated, such as an intermittent line such as a perforation line, or a cut line penetrating the front and back of the paper. In this example, a half cut is employed. More specifically, the first cut 81 and the second cut 82 are formed in parallel, the first cut 81 defines the periphery of the opening, and the second cut 82 is formed outside the first cut 81. Has been. The first cut 81 is formed at a depth from the inside of the container to the middle portion of the paper, and the second cut 82 is formed at a depth from the outside of the container to the middle portion of the paper. When the opening is opened, the first cut 81 and the second cut 82 are opened by being connected by delamination of the paper at an intermediate portion of the paper, and when opened, as shown in FIG. In addition, the delamination portion 83 is formed on the periphery of the opening. By adopting this half-cut, separation can be performed without providing portions penetrating the front and back of the paper of the container, so that both improved sealing and ease of opening can be achieved. In this example, the opening is formed in the upper surface portion 31 and the front surface portion 41 connected to the upper surface portion 31, but is not formed in the front surface portion 41 and is formed only in the upper surface portion 31. You may make it do.
As described above, the portions defined by the first cut 81 and the second cut 82 are the main body upper separation portion 84 formed on the upper surface portion 31 and the main body front separation portion 85 formed on the front surface portion 41. Are collectively referred to as a main body separation unit 86. The main body separating unit 86 opens and closes the opening.
In addition, although the 1st cut 81 and the 2nd cut 82 showed the thing of a straight line, when a person cuts a hand at the edge part of the 1st cut 81 by making not only this but the 1st cut 81 into a wavy line, I can reduce my fear. Thus, the specific shapes of the first cut 81 and the second cut 82 can be changed as appropriate.

As shown in FIG. 1, as shown in FIG. 1, the separation line 91 is also formed on the covering portion 10 b that is overlapped and bonded to the surfaces of the upper surface portion 31 and the front surface portion 41. The separation line 91 is configured by the second separation lines p2 and p2, the third separation lines p3 and p3, and the fourth separation lines p4 and p4 described above. As shown in FIG. 4 (A), the separation line 91 corresponds to the separation line (the first cut 81 and the second cut 82) of the container main body when the covering portion 10b is overlaid on the surface side of the container main body. It is formed so as to be located slightly outside, and an intermittent line such as a perforation is suitable, but may be changed as appropriate under the condition that it can be separated. By this separation line 91, the covering portion 10 b (the upper covering portion 11 and the front covering portion 21) is partitioned into a remaining portion 92 and a separating portion 93. As described above, the upper covering portion 11 is partitioned into the upper covering remaining portion 12 and the upper covering separating portion 13, and the front covering portion 21 is separated from the previous remaining covering portion 22 and the previous covering separating portion 23 at the second separation line p2. The top coating remaining portion 12 and the front coating remaining portion 22 are further continuous with the top coating separating portion 13 and the front coating separating portion 23 via the fifth fold line m5.

Accordingly, the lid 100 (FIG. 4A) for opening and closing the opening is formed by the separation line (first cut 81 and second cut 82) and the separation line 91 of the container main body. Become. The lid body 100 is obtained by bonding the main body separating portion 86 and the separating portion 93, and the base end thereof has a fourth fold line m4 between the rear surface portion 61 and the covering portion 10b (upper covering portion 11). As the fold line for the hinge, the container is rotatably connected to the container. The hinge crease line is a crease line between the upper surface and the rear surface in the case of the entire container. However, the present invention is not limited to this, and the hinge crease line may be provided at another position. The lid body 100 corresponds to the lid piece of claim 2.

As described above, the first fold line m1 to the third fold line m3 are folded from the state of FIG. 1 to obtain the state of FIG. Then, from the state shown in FIG. 2, as shown in FIG. 3, at the sixth crease line m6 and the seventh fold line m7, the back portion constituting piece 22b and the guide portion constituting piece 95 are pressed on the back side. It folds so that it may overlap with the back of part 22a and narrow part 97. At this time, the guide part constituting piece 95 is glued to the back surface of the narrow part 97. However, the insertion parts 96, 96 are not bonded to either. Further, the base portion constituting piece 22b may be glued to the holding piece constituting piece portion 22a, avoiding the insertion portions 96, 96, or may be simply folded and not glued.
The guide portion constituting piece 95 provided at the distal end of the separation portion 93 via the sixth fold line m6 is such that the back surface of the guide portion constituting piece 95 is different from the back surface of the narrow portion 97 as described above at the time of manufacturing the container. The guide part constituting piece 95 and the narrow part 97 are integrated with each other, and this state is maintained even after opening (the opening operation and use after opening will be described later).
As described above, since the left and right widths of the guide part constituting piece 95 are formed larger than the narrow part 97 of the separating part 93 to be overlapped, the insertion parts 96, 96 are folded in a folded state. , Protrudes from the narrow part 97 to the left and right. In this example, the insertion parts 96 are formed symmetrically on the left and right ends of the guide part constituting piece 95, respectively.
The insertion portions 96 and 96 that protrude to the left and right from the narrow portion 97 are overlapped with the holding piece constituting portions 22a and 22a together with the base portion constituting pieces 22b and 22b. As described above, the inserting portions 96 and 96 are overlapped. Is not bonded to the holding piece constituent portions 22a, 22a.

The fifth fold line m5 is mountain-folded, and as shown in FIG. 4A, the front covering portion 21 is disposed on the front surface portion 41 of the container body. As described above, when the state shown in FIG. 3 is changed to the state shown in FIG. 4A, the surfaces of the base portion constituting pieces 22b and 22b are glued to the surface of the front face portion 41 of the container body. However, the surface of the base component piece 95 is not bonded to the surface of the front surface portion 41 of the container body.

Further, in the above, the main body upper separation portion 84 and the upper coating separation portion 13 are overlapped and bonded, but the portion between the second cut 82 and the separation line 91 is not bonded. Further, the main body front separation portion 85 and the front covering separation portion 23 are overlapped and bonded, but the portion between the second cut 82 and the separation line 91 is not bonded. Further, the remaining portion 92 (the upper covering remaining portion 12 and the pre-covering remaining portion 22) is bonded to the container main body portion, that is, the upper surface portion 31 and the front surface portion 41. The front cover separation part 23 is bonded to the front body separation part 85, but is not bonded to the front surface part 41 other than the front body separation part 85.

In the container of this embodiment configured as described above, each crease line is folded and each part is glued as necessary, whereby the container shown in FIG. 4A is completed.

Next, opening of this container is demonstrated.
When opening the container, a finger is inserted from the lower end (tip 97a) of the narrow portion 97 shown in FIG. The guide portion constituting piece 95 is pulled up to the front and upper side.
At this time, the guide portion constituting piece 95 is separated from the base portion constituting piece 22b at the fourth separation line p4, and the narrow portion 97 is separated from the holding piece constituting portion 22a at the third separation line p3. As a result, the guide portion constituting piece 95 and the narrow portion 97 rise from the lower side to the front side with the eighth fold line m8 as the center. If the guide portion constituting piece 95 and the narrow portion 97 are continuously pulled up as they are, the front covering separating portion 23 is separated from the holding piece constituting portion 22a by the third separating line p3, and the upper covering separating portion 13 is further separated from the second separating line. At p2, it is separated from the top coating remaining part 12. That is, by the above pulling operation, as shown in FIG. 5, the separation portion 93 and the main body separation portion 86 bonded thereto are opened along the second separation line p <b> 2, the first cut 81, and the second cut 82. It is. Thereby, the lid body 100 is formed, and the lid body 100 rotates around the fourth crease line m4 that is a fold line for hinges to open and close. The lid body 100 includes an upper surface lid portion to which the main body upper separation portion 84 and the upper coating separation portion 13 are bonded, and a front lid portion to which the main body front separation portion 85 and the front coating separation portion 23 are bonded. It becomes.

As described above, the guide part constituting piece 95 is separated from the base part constituting piece 22b at the fourth separation line p4 by the above-described opening and becomes the guide part 95. It can be said that the guide portion 95 integrally formed on the back surface of the narrow portion 97 is a portion that protrudes rearward from the back surface of the narrow portion 97. Further, the base portion constituting piece 22b becomes the base portion 22b by the guide portion constituting piece 95 being cut off as described above, and the locked portion constituting piece 98 becomes the locked portion 98. Further, the pre-cover separation part 23 is separated from the holding piece component 22a by the third separation line p3, whereby the holding piece component 22a becomes the holding piece 22a.
The upper ends of the insertion portions 96, 96 constitute locking portions 96a, 96a, and the lower end of the locking portion 98 of the base portion 22b bonded to the front surface portion 41 of the container body is engaged. It constitutes a stop (locked end).

Next, a case where the lid 100 is closed and the opening is closed will be described.
As shown in FIG. 6 and FIG. 7 (A), the tip of the narrow portion 97 is directed downward and lowered between the left and right pressing portions 22a, 22a. At this time, the insertion portions 96 and 96 temporarily run over the locked portion 98 of the base portions 22b and 22b, and the surface (front surface) of the locked portion 98 of the base portion 22b and the pressing pieces 22a and 22a. It is inserted between the back side (rear side). When the narrow portion 97 is further lowered along the back surface (front surface) of the locked portion 98 of the base portion 22b, the insertion portions 96 and 96 get over the locked portion 98 of the base portion 22b. The plugs 96, 96 are inserted between the front surface portion 41 of the container body and the back surface (rear surface) of the pressing piece 22a . The reason why the plug 96 moves to the rear B is that the insertion portion 96 is urged toward the rear B by the elasticity of the pressing piece 22a. When the narrow portion 97 is further lowered, the insertion portions 96 and 96 come into contact with the fold line (the seventh fold line m7) connecting the base portion 22b and the pressing piece 22a, and the width is further narrowed. The part 97 cannot be lowered. In this way, as shown in FIG. 7B, the narrow portion 97 is disposed between the pressing pieces 22a and 22a in the front view of the container. In the state where the narrow portion 97 is positioned in this manner, the insertion portion 96 is sandwiched between the back surface of the pressing piece 22a and the front surface portion 41 of the container as shown in FIG. 4B. In this state, the upper ends 96a and 96a of the insertion portions 96 and 96 that are the locking portions abut on the lower ends 22c and 22c of the locked portion 98 of the base portion 22a that is the locked portion. That is, the locking portion is locked to the locked portion, and the narrow portion 97 cannot be retracted upward. In this way, the guide portion 95 is arranged in the same manner as before opening (when it is the guide portion constituting piece 95) shown in FIG. It contacts the front surface of the main body (front surface 41 surface).
In this example, the insertion portion 96 is provided on both the left and right sides of the guide portion 95, and the inserted portion is also provided on the left and right sides accordingly, but the insertion portion 96 and the inserted portion are either left or right. You may make it provide only in either.

As described above, when the locking part is locked to the locked part, even if the container is lifted by mistake by holding only the separation part 93, the separation part 93 is locked to the container body part. Therefore, the possibility of spilling stored items such as powder detergent can be reduced.

Further, in the above, the narrow portion 97 is positioned in front of the front surface portion 41 of the container by the thickness of the guide portion 95. Moreover, the insertion part is housed in the position shown in FIG. 4B, and the pressing piece 22a overlapped with the base part 22b is positioned forward of the front part 41 of the container by the thickness of the base part 22b. Since each of these parts is formed of a single sheet, the above-mentioned thicknesses are all the same, and the left and right holding pieces 22a are as shown in FIG. 7B and the surface of the holding piece 22a. , 22a sandwiched between the surfaces of the narrow portions 97 in the front-rear direction is almost the same surface and looks good, and it is also possible to print patterns and explanations straddling both.

When the lid closed by the above operation after opening is opened again, the same operation as that at the time of opening is performed, that is, by picking the narrow portion 97 and rotating the tip about the eighth fold line m8. The insertion portion 96 may be pulled out upward from the pressing piece 22a while expanding the pressing piece 22a forward against the elasticity of the pressing piece 22a.

In the example described above, the lid body 100 is provided over the two surfaces of the container (on the upper surface and the front surface). However, the lid body 100 may be provided only on one surface of the container.
Although not shown, for example, the opening may be provided only on the upper surface (or front surface), and the lid 100 may be provided only on the upper surface (or front surface) correspondingly.
In this case, in the covering portion, the pre-covering portion is not necessary, but a portion corresponding to the pre-covering separation portion 23 is provided in the sheet. By providing such a separation portion and providing the fifth fold line m5, the lid can bend and stretch at the fifth fold line m5, and the insertion portion can be smoothly inserted into the insertion portion. It is because it can be performed.
In this case, the lid body 100 may be cut off in the vertical direction with respect to the hinge crease line, or may be cut off in an oblique direction.
Furthermore, in the example described above, the covering portion 10b is superimposed on the upper surface portion 31, but the upper surface portion 31 is omitted and the upper surface of the container is covered only with the upper covering portion 11. It may be configured.

Although the surface which appears in FIG. 1 was demonstrated as the surface of a sheet | seat, this surface is formed as a decorative surface. On the other hand, since the back side of the sheet is not a decorative surface, it looks bad and it is desirable to suppress the exposure. However, as shown to FIG. 7 (A), the base part 22b orient | assigns the back surface side of a sheet | seat to the front surface of a container. Therefore, in the state shown in FIG. 1, the widths of the front and rear f and b of the base portion constituting piece 22b are the same as or smaller than the front and rear widths of the portion of the front covering remaining portion 22a extending in the lateral direction toward the narrow portion 97. As shown in FIG. 7C, most of the pedestal portion 22b can be concealed in the pressing piece 22a in the front view of the container after the container is formed.

For example, as shown in FIG. 8, the width of the front and rear f and b of the base portion constituting piece 22b is the width of the front covering remaining portion 22a before and after the laterally extending portion 23d extending in the lateral direction toward the narrow portion 97. The base 22b can be hidden behind the pressing piece 22a after forming the container. In addition to the above, in the embodiment shown in FIG. 8, the positions of the upper and lower portions of the left and right lower surface flaps 75 and 76 are opposite to those of the seat shown in FIG. Forms such as the first to third sides provided on the edge pieces of 78 are formed on the edges of the front flaps 73 and 74 instead of the rear flaps 77 and 78, and the front flaps 73 and 74 are formed on the lower surface. The configuration other than facing the lower portions of the flaps 75 and 76 and the ruled line 52 provided on the rear surface portion 61 in the sheet of FIG. 1 is provided on the front surface portion 41 are shown in FIG. This is the same as the embodiment.

If the proportion of the front covering portion on the front surface of the container body is large, the design of the design or the like on the front surface of the container becomes difficult to see due to the step between the surface of the front covering portion 21 and the front surface portion 41 of the container. Is preferably printed on the rear side of the container.
However, during use, consumers often see the front of the container body from the rear, etc., so they want to print a large trademark or other pattern that occupies most of the surface on the front of the container body. .
Therefore, the widths of the upper and lower U and S of the pressing piece 22a (the widths of the front and rear f and b of the pressing piece constituting portion 22a) are not fixed, but as shown in FIG. The separation line p3 is curved so as to be convex upward and downward, and a neck portion 22e having a smaller vertical width t2 than the distal end side is formed on the pressing piece 22a. The vertical width t1 can be made relatively large, and the overall vertical width t of the pressing piece 22a can be kept small. Along with this, the upper and lower widths of the narrow portion 97 can be formed small.
In this way, by suppressing the proportion of the front clothing portion, it is possible to print a trademark or other pattern on the surface of the front surface portion 41 of the container.

In the example shown in FIGS. 7A to 7D, the base portion 22 b is provided at two places on the left and right sides of the narrow portion 97, and as a result, includes two locked portions 98.
In addition, as shown in FIG. 9, the left and right locked portion constituting pieces 98, 98 located in front of the guide portion constituting piece 95 are integrally formed, that is, the locked portion constituting piece 98 is It can also be carried out by being formed in a continuous manner along the entire front end of the guide part constituting piece 95. In this case, although not shown, the locked portion 98 formed by assembling the container provides a locked portion corresponding to all of the upper end 96a of the guide portion 95, and the entire upper end 96a of the guide portion 95 It becomes the latching | locking part (locking end) latched by the to-be-latched part.

Finally, in relation to the display of the container, the surface on which the design such as the design of the container is applied will be summarized. In the container formed of the sheet-like body shown in FIG. 1, it is preferable to print a main design of the container such as a character or a trademark on the surface with the front surface portion 41 as the front surface. Further, in the container shown in FIGS. 8 and 9, it is preferable to print a main design of the container such as a character or a trademark on the surface with the rear surface portion 61 as the front surface. This is because by printing on the front surface of each of the embodiments, the design can be printed neatly on a surface with few undulations.
