Abstract

The sheet (10) for the container holding frame is divided into an outer frame part (11), a leg part (12) and a bottom part (13) by a plurality of dividing lines. The leg parts (12) extend along the four sides of the bottom part (13), one end of each leg part (12) in the length direction is connected with the outer frame part (11), and the other end of each leg part (12) in the length direction is connected with the bottom part (13). The dividing line is composed of an outer side line (12c) and an inner side line (12d) which are located on the two sides of the leg part (12), and a closed space completely surrounded by the dividing line does not exist on the sheet (10). When the bottom part (13) is pressed below the outer frame part (11), the container holding frame is deformed.

Description

Technical Field

[0001] The present invention relates to a sheet for a container holding frame which is transformed into a container holding frame and a container with a holding frame using the sheet for a container holding frame. Background Art

[0002] A container for storing food such as dishes and side dishes, which is formed by punching a film, paper, or the like, is known. As described in Patent Document 1, a holding frame for holding such a container is also known.

[0003] Here, the holding frame is produced by deforming a sheet of container holding frame having dividing lines. The container holding frame sheet is divided into an outer frame portion, a leg portion surrounded by the outer frame portion, and a bottom portion surrounded by the leg portion by a plurality of dividing lines.

[0004] Each of the legs extends along the outer periphery of the bottom portion, and one end in the length direction thereof is connected to the outer frame portion, and the other end in the length direction thereof is connected to the bottom portion.

[0005] Moreover, if the bottom of the horizontally supported sheet is pushed downward than the outer frame, each of the legs is bent downward at the boundary with the outer frame, thereby deforming three-dimensionally into a state in which multiple legs stand up from the bottom toward the outer frame located higher than the bottom.

[0006] The container is held in the storage space between the bottom portion and the leg portion formed in this way.

[0007] The container containing the food is packaged in a packaging bag or the like in the state of a container with a holding frame held by the holding frame and is sold.

[0008] Patent Document 1: Japanese Patent No. 4988387

[0009] However, in the existing sheet material for container holding frames, multiple dividing lines are connected, thereby forming a closed space surrounded by the dividing lines on the sheet material, so this part needs to be removed as an unnecessary part. Usually, this part is separated and removed in the dividing line formation process when the sheet material is manufactured, but occasionally this part may not be completely separated from the sheet material and remain. In addition, even if this part can be completely separated from the sheet material, the separated fragments may directly adhere to the sheet material as chips and remain. If such fragments remain when the sheet material is used, it will become a foreign matter, so it is not preferred. Especially when used for food storage purposes, bringing such fragments into the food packaging production line of the food structure becomes a problem in terms of hygiene, so it is necessary to prevent this phenomenon.

[0010] Therefore, as long as fragments are generated, the above situation cannot be completely prevented. Summary of the invention

[0011] Therefore, an object of the present invention is to prevent the generation of fragments separated from a sheet material for a container holding frame that is deformed into a container holding frame.

[0012] In order to solve the above-mentioned problems, the sheet material for container holding frame involved in the invention is composed of: a sheet body having multiple dividing lines or easily breaking lines, divided by the multiple dividing lines or easily breaking lines into an outer frame portion, a leg portion surrounded by the outer frame portion, and a bottom portion surrounded by the leg portion, each of the legs extends along the outer periphery of the bottom, and one end thereof in the length direction is connected to the outer frame portion, and the other end thereof in the length direction is connected to the bottom, if the bottom of the sheet body is pushed lower than the outer frame portion, each of the legs is bent downward at the boundary with the outer frame portion, thereby forming a storage space capable of holding a container between the bottom and the legs, and the dividing lines are configured so that there is no closed space on the sheet body that is completely surrounded by the dividing lines or easily breaking lines.

[0013] Here, the easy-to-break line refers to a line that breaks when the container holding frame sheet is deformed, and examples thereof include perforations and half-cut lines.

[0014] According to this structure, at least a part of any portion on the sheet body is connected to another portion and does not separate from the sheet body, so generation of fragments can be prevented.

[0015] Therefore, it is possible to prevent such fragments from remaining when the sheet is used. In particular, when used for food storage purposes, it is possible to prevent the fragments from mixing in as foreign matter.

[0016] In the sheet material for the container retaining frame involved in the invention, the following structure is preferably adopted: a plurality of dividing lines or easily breakable lines are composed of a plurality of side line pairs, and the side line pairs are composed of outer lines that divide the outer sides of each leg from the outer frame portion, and inner lines that divide the inner sides of each leg from the bottom portion; between adjacent side line pairs, the inner lines of one side line pair are connected to the outer lines of another side line pair, and the outer lines of one side line pair are separated from the inner lines of another side line pair.

[0017] According to this structure, it is easy to arrange the dividing line or the easy break line so that there is no closed space completely surrounded by the dividing line or the easy break line on the sheet body.

[0018] Therefore, generation of fragments separated from the sheet body can be easily prevented.

[0019] In addition, in the sheet material for the container retaining frame involved in the invention, the following structure is preferably adopted: the inner periphery of the outer frame portion and the outer periphery of the bottom are roughly square, each of the legs extends along the four sides of the inner periphery of the outer frame portion and along the four sides of the outer periphery of the bottom, and one end thereof in the length direction is respectively connected to the four corners of the inner periphery of the outer frame portion, and the other end thereof in the length direction is respectively connected to the four corners of the outer periphery of the bottom.

[0020] If constructed in this way, it is easy to stably store containers that are usually formed by stamping films, paper, etc. and are circular when viewed from above in the storage space. In addition, the structure is relatively simple, so it becomes relatively easy to configure the dividing lines, etc. so that there is no closed space on the sheet body that is completely surrounded by the dividing lines, etc.

[0021] In addition, in order to solve the above-mentioned problems, the container with a retaining frame involved in the invention is constructed to include: a container retaining frame, which is formed by deforming the above-mentioned container retaining frame sheet and can retain the container in a storage space between the bottom and the legs standing up from the bottom; and a container, which is retained in the storage space.

[0022] Since the container holding frame sheet or the like according to the present invention is configured as described above, it is possible to prevent the generation of fragments separated from the sheet body. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0045] for Figure 1A and Figure 1B The container holding frame sheet 10 of the embodiment shown is deformed to assemble the container holding frame 10 of the embodiment for holding the container 20 containing food or the like.

[0046] like Figure 1A As shown, the container holding frame sheet 10 of the embodiment is a sheet body and has a substantially square shape as a whole, and its four corners are rounded in an arc shape.

[0047] The container holding frame sheet 10 has a plurality of dividing lines and is divided into an outer frame portion 11 , a leg portion 12 , and a bottom portion 13 .

[0048] The material of the sheet body forming the container holding frame sheet 10 is not particularly limited, and examples thereof include paper, synthetic resin film, metal foil such as aluminum foil, or a composite thereof. Paper is preferred as an environmentally friendly material that is easily discarded or incinerated.

[0049] The size of the container holding frame sheet 10 is not particularly limited, and the size of the container 20 of a normal size that can hold food such as dishes, side dishes, frozen food, etc. as the contained object when it has been deformed into the container holding frame 10 can be exemplified as a side length of 100 mm to 150 mm. In addition, the contained object is not limited to food.

[0050] like Figure 1A As shown, the outer frame portion 11 is composed of a square ring-shaped frame body 11 a and a cross-shaped partition frame 11 b.

[0051] The portion surrounded by the frame body 11a of the container holding frame sheet 10 is divided into four parts by two rows each in front, back, left and right by the partition frames 11b, each forming a square container holding portion.

[0052] like Figure 1A As shown, holes 11c extending from the inner periphery to the outer periphery are formed at four corners of the frame body 11a of the outer frame 11. The ring of the outer frame 11 can be opened by breaking the holes 11c.

[0053] The partition frame 11b of the outer frame 11 has a cross-shaped hole 11d that crosses the outer frame 11 in the vertical and horizontal directions. The outer edge of the hole 11d of the outer frame 11 has a notch 11e that serves as a starting point for breaking the hole 11d.

[0054] By breaking the eyelets 11 c , the container holding portions can be individually separated.

[0055] When the container holding frame sheet 10 is deformed, the outer frame portion 11 serves as a frame that supports the container holding portion.

[0056] The outer dimensions of the outer frame 11 match the dimensions of the container holding frame sheet 10. The widths of the frame body 11a and the partition frame 11b of the outer frame 11 are not particularly limited, but may be 3 mm to 20 mm, more preferably 8 mm to 12 mm.

[0057] If the width is less than 3 mm, the strength of the outer frame 11 is insufficient and may break during deformation. If the width is greater than 20 mm, the overall size of the container holding frame sheet 10 will also increase, and the size of the packaging body after deformation may also increase accordingly.

[0058] like Figure 1A As shown, the four legs 12 in each container holding portion are each in the shape of an elongated rectangle, and are adjacently arranged so that the longitudinal direction thereof extends along the four sides of the inner periphery of the outer frame portion 11 .

[0059] One end (outer end) of both ends of each leg 12 is connected to the outer frame 11. A fold line 12a is formed as an easy-bend fold line at the boundary between the leg 12 and the outer frame 11. The fold line 12a extends along the inner circumference of the outer frame 11. The leg 12 can be bent relative to the outer frame 11 through the fold line 12a.

[0060] In addition, each leg portion 12 and the outer frame portion 11 are separated by a linear outer line 12 c as a dividing line except for the above-mentioned connection portion.

[0061] The outer line 12c is curved in an arc shape at the boundary between the leg portion 12 and the outer frame portion 11. Thus, the leg portion 12 is widened near the boundary with the outer frame portion 11 and is reinforced.

[0062] When the container holding frame sheet 10 is deformed, the leg portions 12 support the outer periphery of the container 20 .

[0063] The size of the leg 12 is not particularly limited, and as a size suitable for properly supporting the outer periphery of a container 20 such as a side dish cup, a length of 20 mm to 80 mm, more preferably 40 mm to 50 mm, and a width of 2 mm to 15 mm, more preferably 5 mm to 7 mm can be exemplified.

[0064] If the length is less than 20 mm, the height of the container 20 when filled with food, etc. will exceed this height and overflow from the container holding frame 10, and the container 20 may not be fixed in the storage space of the container holding frame 10. If the length is greater than 80 mm, it becomes too large compared to the height of a normal container, and the container 20 may shift and move in the storage space.

[0065] In addition, if the width is less than 2 mm, the strength of the leg 12 is insufficient and it may break during deformation. If the width is greater than 15 mm, the leg 12 becomes too large. When it is bent at the boundary with the bottom 13 and the outer frame 11 described later during deformation, the strength of the leg 12 becomes too strong and it may be difficult to deform it. The overall size of the sheet 10 for the container holding frame also increases, and the size of the packaging body when it is packaged after deformation may also increase accordingly.

[0066] like Figure 1A As shown, the bottom portion 13 of each container holding portion has a substantially square shape, and is adjacently arranged such that the four sides of the outer circumference thereof are along the four leg portions 12 .

[0067] The end (inner end) of each leg 12 on the side opposite to the side connected to the outer frame 11 is connected to the bottom 13. A fold line 12b is formed as an easy-bend fold line at the boundary between the leg 12 and the bottom 13. The leg 12 can be folded relative to the bottom 13 through the fold line 12b.

[0068] In addition, each leg portion 12 and the bottom portion 13 are divided by a linear inner line 12 d as a dividing line except for the above-mentioned connection portion.

[0069] When the container holding frame sheet 10 is deformed, the bottom portion 13 supports the bottom of the container 20 .

[0070] The size of the bottom portion 13 is not particularly limited, but as a size suitable for appropriately supporting the bottom of the container 20 such as a side dish cup, a side length of 20 mm to 80 mm, more preferably 30 mm to 40 mm, can be exemplified.

[0071] If the length of the side is less than 20 mm, it is smaller than the size of the bottom of a normal container 20 and the container 20 may not be able to be accommodated. If the length of the side is greater than 80 mm, it becomes too large compared to the size of the bottom of a normal container 20 and the container 20 may shift, move or tip over in the storage space.

[0072] Here, if Figure 1A As shown, the outer line 12c and the inner line 12d located on both sides of each leg 12 form a pair of parallel side line pairs. In each container holding portion, there are four side line pairs corresponding to each leg 12. Adjacent side line pairs are substantially perpendicular to each other.

[0073] Between two adjacent side line pairs, the outer line 12c of one side line pair is connected to the inner line 12d of the other side line pair to form an L-shaped dividing line, but the inner line 12d of one side line pair and the outer line 12c of the other side line pair are separated and not connected with each other with the inner line 12d of the other side line pair sandwiched therebetween.

[0074] In this way, Figure 1A As shown, as for the dividing lines, four L-shaped dividing lines formed by connecting the outer line 12c and the inner line 12d are arranged in a so-called swastika shape in each container holding portion.

[0075] Therefore, there is no closed space completely surrounded by the dividing lines connected in series in the container holding frame sheet 10. Therefore, the existence of fragments generated from the container holding frame sheet 10 due to the existence of such a closed space is avoided.

[0076] Therefore, it is suppressed that the fragments remain in the punching process of the container holding frame sheet 10 or the deformation process described later, or that the fragments are mixed as foreign matter in the packaging process.

[0077] Here, if Figure 1A As shown, in this embodiment, the fold line 12b of the boundary between the leg 12 and the bottom 13 is formed obliquely to cross the corner of the bottom 13 from the end of the inner line 12d of one of the two adjacent side line pairs to the middle of the inner line 12d of the other side line pair.

[0078] The structure of the container holding frame sheet 10 of the embodiment is as described above. Figure 2A to Figure 3 , an example of a deformation method (assembly method) of the container holding frame 10 is described.

[0079] For example, first, Figure 2A and Figure 2B As shown, in a state where the outer frame portion 11 of the container holding frame sheet 10 is supported in a horizontal state, the bottom portion 13 of the container holding portion is pressed downward.

[0080] Then, the leg portion 12 of the container holding portion is interlocked with the outer frame portion 11 and is bent downward at the fold line 12 a at the boundary with the outer frame portion 11 .

[0081] As the bottom 13 descends, the fold line 12b at the boundary between the bottom 13 and the leg 12 also bends in a mountain fold when viewed from above. At this time, the bottom 13 rotates along the horizontal plane so that its four corners are offset from the four corners of the inner circumference of the outer frame 11.

[0082] The folding lines 12a and 12b allow the leg 12 to be folded smoothly at the boundaries between the outer frame 11 and the bottom 13. Figure 2A The container holding frame sheet 10 shown is formed into a concave shape when viewed from the upper surface side. Thus, the folds at these boundaries can be regularly controlled. However, it is not excluded to form a convex shape. In addition, the fold lines 12a and 12b are not necessarily required, and it is also possible to form only one of them or neither of them.

[0083] Furthermore, since the positions of the bends are limited to the positions where the fold lines 12a and 12b are formed, the bend positions and heights are consistent between the leg portions 12, thereby suppressing the occurrence of defective products.

[0084] In this way, the container holding frame 10 is completed. In the present embodiment, the bottom portion 13 of the container holding frame 10 is lifted up from the lower end of the leg portion 12 according to the position and direction of the fold line 12 b.

[0085] Here, as described above, the outer line 12c is curved in an arc shape at the boundary between the leg 12 and the outer frame 11, so the grounding part at the lower end of the leg 12 is round. Therefore, even when a load is applied, buckling can be prevented, and unlike the case where the grounding part is sharp, fingers will not be pricked.

[0086] The bottom portion 13 is raised, thereby preventing dirt and the like from being attached to the back surface of the bottom portion 13 .

[0087] A three-dimensional storage space is formed between the bottom 13 and the legs 12 and is opened on the outer frame 11. Figure 3 As shown, the storage space stores a container 20 filled with frozen food or the like.

[0088] In the embodiment, four containers 20 are stored in four container holding portions.

[0089] In this state, the product is packaged in a packaging bag, a packaging box, etc. and sold.

[0090] After a consumer who has purchased the product unpacks the package, he or she can break the holes 11 d formed in the partition frame 11 b of the outer frame 11 to take out a required amount of the containers 20 stored in the container holding portion.

[0091] Furthermore, when it is desired to separate the container 20 from the container holding frame 10 , the eyelet 11 c formed in the frame body 11 a of the outer frame 11 is broken, so that the wheel of the outer frame 11 can be opened and taken out.

[0092] Here, the type of container 20 is not particularly limited. Figure 2A and Figure 3 In the embodiment, a container 20 called a side dish cup or the like is exemplified by stamping a sheet body such as paper, a synthetic resin film, a metal foil such as an aluminum foil, or a composite thereof.

[0093] The container 20 has a bottom wall 21 which is substantially circular in a plan view, and a peripheral wall 22 which extends and rises from the bottom wall 21. The peripheral wall 22 has folds 22a formed by press forming. The container 20 is opened upward and can be filled with products or the like through the opening.

[0094] Thus, the peripheral wall 22 of the container 20 is formed with projections and depressions like gears due to the folds 22 a , and thus engages with the leg portions 12 of the container holding frame 10 and the opening edge of the outer frame portion 11 .

[0095] In this way, the container with a holding frame is constituted, and its integrity is improved to prevent the container 20 from falling out of the storage space of the container holding frame 10.

[0096] The embodiments disclosed this time are illustrative in all aspects and are not restrictive.

[0097] The scope of the present invention is indicated by the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims.

[0098] For example, the method of transforming the container holding frame sheet 10 into the container holding frame 10 is not limited to manual work as in the embodiment, and automation can be attempted using a jig or the like.

[0099] As one example, Figure 4A and Figure 4B As shown, there can be mentioned a mode in which a jig J is used in which the interior of a prismatic main body J1 is partitioned by a cross frame J2 and a guide G is attached. The bottom of the main body J1 is closed.

[0100] In this case, the container holding frame sheet 10 placed on the fixture J is first positioned by the guide G, the frame body 11a of the outer frame portion 11 of the container holding frame sheet 10 is supported approximately horizontally by the upper end surface of the body J1, and the partition frame 11b of the outer frame portion 11 is supported approximately horizontally by the upper end surface of the cross frame J2.

[0101] Further from this state, Figure 5A and Figure 5B As shown, the container 20 is placed on each container holding portion.

[0102] Then, if Figure 6A to Figure 6C As shown, the pusher P is lowered from above toward the container holding portion on which the container 20 is placed, and the bottom 13 and the legs 12 are pushed together with the container 20 to transform them into the container holding frame 10. Alternatively, the pusher P may be not used but pushed by hand.

[0103] In this case, the deformation from the container holding frame sheet 10 to the container holding frame 10 and the installation of the container 20 in the storage space are performed simultaneously.

[0104] Of course, the same process may be performed without placing the container 20 on the container holding portion, and the container 20 may be placed after the container holding frame 10 is transformed into the container holding frame 10 .

[0105] Furthermore, after placing the container 20 filled with frozen food or the like on the container holding portion, the bottom 13 can be lowered together with the food and the container 20 using the pusher P in the same manner.

[0106] In this case, the amount of descent of the pusher P becomes smaller than that in a state where nothing is placed on the container holding portion but only the container 20 is placed.

[0107] Alternatively, a hole can be opened in the closed bottom of the clamp J, and a shaft with a suction cup installed on the upper end can be inserted into the hole in a liftable manner. After the suction cup is adsorbed on the bottom 13, the shaft is lowered, thereby stretching the bottom 13 downward and deforming it into a container holding frame 10.

[0108] The position and direction of the fold line 12 b at the boundary between the bottom 13 and the leg 12 are not limited to the embodiment. For example, the fold line 12 b may be formed in a direction orthogonal to the longitudinal direction of the leg 12 .

[0109] In addition, for example, Figure 7 As shown, the fold line 12b can also be formed to cross the inside of the leg 12 from the end of the inner line 12d to the middle of the outer line 12c of each side line pair. In addition, although not shown, it can also be formed obliquely to pass through the entire inside of the leg 12 from the end of the inner line 12d to the uppermost end of the outer line 12c.

[0110] Therefore, if Figures 8A to 10C As shown, similar to the embodiment, if the bottom 13 is pushed downward using a pusher P, the fold line 12b is bent in a valley shape when viewed from above, and in the completed container holding frame 10, the bottom 13 and the lower end of the leg 12 are located in the same plane.

[0111] Thus, when the deformation process is automated and the container holding frame 10 is conveyed by a conveyor or the like, the legs 12 do not protrude downward from the bottom 13, thereby preventing the legs 12 from being caught in the seams of the conveyor or the like.

[0112] Furthermore, when the leg 12 is formed obliquely to pass through the entire interior of the leg 12 from the end of the inner line 12d to the uppermost end of the outer line 12c, the leg 12 itself is obliquely bent at the fold line 12b, so that the strength of the leg 12 is improved.

[0113] In this way, if a fold line 12b is formed inside each side line pair from the end of the inner line 12d to the middle of the outer line 12c, the protrusion of the leg 12 below the bottom 13 becomes smaller. On the contrary, if a fold line 12b is formed from the end of the inner line 12d of one of two adjacent side line pairs to the middle of the inner line 12d of the other side line pair as in the embodiment, the protrusion of the leg 12 below the bottom 13 becomes larger.

[0114] That is, the fold line 12b is formed from the end of the inner line 12d to the outer line 12c. Fig.11 When the fold line 12b is formed at position A, the protrusion of the leg 12 below the bottom 13 becomes larger. When the fold line 12b is formed at position C, the protrusion of the leg 12 below the bottom 13 becomes smaller. When the fold line 12b is formed at position B, the protrusion is in the middle.

[0115] By making the direction and position of the fold line 12 b different in this way, the relative height relationship between the bottom portion 13 and the outer frame portion 11 and the leg portion 12 can be appropriately adjusted according to the application and the like.

[0116] The shapes of the outer frame portion 11 , the legs 12 , the bottom portion 13 , and the container holding portion, and the numbers of the legs 12 , the bottom portion 13 , and the container holding portion are not limited to those in the embodiment.

[0117] For example, Fig.12 As shown, an opening (hole) 13a can also be provided at the bottom 13. When the jig J is used as described above, when a hole is opened at the closed bottom of the jig J, a shaft with a suction cup attached to the upper end is inserted into the hole so as to be able to be raised and lowered, and the suction cup is adsorbed to the bottom 13, and then the shaft is lowered, so that the bottom 13 is stretched downward, and the bottom 13 can be deformed into the container holding frame 10 and the container holding frame 10 can be set on the jig J. However, when an opening is formed at the bottom 13 of the sheet 10 for the container holding frame, the shaft can be continuously raised and lowered even after the container holding frame 10 is set on the jig J. Therefore, the container 20 can be set on the container holding frame 10 using such an adsorption mechanism by passing through the opening 13a formed at the bottom 13 of the container holding frame 10, and then the suction cup of the shaft is adsorbed to the bottom of the container 20, and then the shaft is lowered. In addition, by forming the opening 13a at the bottom 13, when removing the container 20 from the container holding frame 10, the bottom of the container 20 can be directly pressed with fingers, so that the detachability of the container 20 is also improved. Furthermore, compared with the fragments that were a problem in the prior art, the size of the opening 13 a is larger, so it is easy to separate and remove when manufacturing the container holding frame sheet, so there is no problem even if such an opening is formed in the bottom 13 .

[0118] Alternatively, the bottom 13 may be a polygon other than a square (e.g., a triangle, a pentagon, or a hexagon), and the legs 12 may be the same number of sides as the outer edges of the polygon (e.g., three sides for a triangle, five sides for a pentagon, or six sides for a hexagon).

[0119] The width of the leg 12 may not be constant, but may taper toward the bottom 13 or toward the outer frame 11, or may have a corrugated outer edge. The outer frame 11 may be in a ring shape other than a square ring, such as a circular ring or a rectangular ring.

[0120] In the embodiment, the container holding portion is set to 2 rows in front, back, left, and right, totaling four, but it can also be set to 3 rows in front, back, left, and right, or the number of rows can be different in the front-back direction and the left-right direction, such as 1 row in front, back, and left, right, etc. In addition, it is also possible to set the container holding portion to only one. In addition, if the shape of the container holding portion is a hexagon, it can also be arranged at a position along each side of the outer periphery of the polygon almost without gaps in a so-called honeycomb structure. Therefore, its configuration is not limited.

[0121] The arrangement of the dividing lines such as the outer line 12c and the inner line 12d is not limited to the embodiment, as long as the arrangement is such that there is no closed space surrounded by the dividing lines on the container holding frame sheet 10. Thus, the generation of fragments such as punching waste can be prevented. In addition, the dividing line can also be an easy-to-break line such as a perforation or a half-cut line, or a combination thereof.

[0122] The fold line 12 a at the boundary between the outer frame 11 and the leg 12 , the fold line 12 b at the boundary between the leg and the bottom 13 , the holes 11 c , 11 d , and the notch 11 e of the outer frame 11 may also be omitted.

[0123] In the embodiment, the fold lines 12a and 12b are exemplified as the easy-bend fold lines, but the present invention is not limited thereto, and other easy-bend fold lines such as half-cut lines and eyelets may be used.

[0124] The outer line 12c and the inner line 12d as the dividing lines of the embodiment may be replaced with easy-to-break lines such as half-cut lines and perforations to break the container holding frame sheet 10 when it is deformed.

[0125] The easy bending line and the easy breaking line are preferably different types of lines because they can be easily distinguished. For example, one is a half-cut line and the other is an eyelet.

[0126] In addition, other easy-to-break lines such as half-cut lines may be used instead of the eyelets 11c and 11d.
