Sheet for container holding frame

Abstract

To provide a sheet for a container holding frame that is deformed into a container holding frame, which can easily prevent a container in a storage space from being positionally deviated and detached.SOLUTION: A sheet 10 for a container holding frame is comparted by a plurality of cut lines into an outer frame part 11, leg parts 12 and bottom parts 13. The leg part 12 extends along four sides of the bottom part 13, whose one end in a longitudinal direction is connected to the outer frame part 11 and whose other end in the longitudinal direction is connected to the bottom part 13. The bottom part 13 is constituted of a main body 13a of the bottom part and a flip-up piece 13b. When the bottom part 13 is pressed downward more than the outer frame part 11, the bottom part folds downward at a boundary between the leg part 12 and the outer frame part. This can deform the sheet into a container holding frame, so that a storage space that can hold a container is formed between the bottom part 13 and the leg part 12. Before and after the space is formed, only the flip-up piece 13b of the bottom part 13 is folded upward. Accordingly the flip-up piece 13b standing up from the main body 13a of the bottom part surrounds the container in the storage space, which can easily prevent the container from being positionally deviated and detached.SELECTED DRAWING: Figure 1

Description

[Technical Field]

[0001] The present invention relates to a sheet for a container-holding frame that can be transformed into a container-holding frame, and a framed container using the same. The present invention also relates to a method and an apparatus for manufacturing a container-holding frame using a sheet for a container-holding frame. [Background technology]

[0002] Containers made by pressing film, paper, etc. for storing food such as prepared dishes and side dishes are known, and holding frames for holding these types of containers are also known, as shown in Patent Document 1.

[0003] The frame is made by deforming a single sheet of sheet material with score lines cut into it. The sheet material is divided by the score lines into an outer frame, a leg portion surrounded by the outer frame, and a base portion surrounded by the leg portion. Each of the legs extends along the outer periphery of the bottom, and has one end in the longitudinal direction connected to the outer frame and the other end in the longitudinal direction connected to the bottom.

[0004] When the bottom of the horizontally supported seat is pushed below the outer frame, each leg bends downward at the boundary with the outer frame, causing the seat to be deformed three-dimensionally with multiple legs standing up from the bottom toward the outer frame, which is positioned higher than the bottom. The container is held in the storage space thus formed between the base and the legs. The container containing the food is then packaged in a packaging bag or the like while still held in the frame, and is then sold. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Patent No. 4988387 Summary of the Invention [Problem to be solved by the invention]

[0006] However, with conventional container holding frame sheets, depending on the shape and dimensions of the container, when the sheet is deformed or when it is transported after deformation, the container may become misaligned within the storage space or may fall out of the storage space. If the container becomes misaligned or detached in this way, it can cause problems in subsequent processes, such as filling the food with food or wrapping it in film or the like. On the other hand, if a separate jig or other device is required to prevent the container from shifting position or coming off, the structure becomes more complex and costs increase.

[0007] Therefore, an object of the present invention is to easily prevent displacement or detachment of containers within a storage space from occurring in a sheet for a container holding frame that is transformed into a container holding frame. [Means for solving the problem]

[0008] In order to solve the above-mentioned problems, the sheet for a container holding frame of the invention consists of a single sheet body with multiple score lines or easy-to-break lines, and is divided by the multiple score lines or easy-to-break lines into an outer frame portion, legs surrounded by the outer frame portion, and a single or multiple parallel bottom portions surrounded by the legs, each of the legs extending along the outer periphery of the bottom portion, with one longitudinal end connected to the outer frame portion and the other longitudinal end connected to the bottom portion, and when the bottom of the horizontally supported sheet body is pushed below the outer frame portion, each of the legs bends downward at the boundary with the outer frame portion, thereby forming a storage space between the bottom and the legs that can hold a container, and the bottom portion consists of a bottom main body and a flip-up piece attached to the outer edge of the bottom main body, and the flip-up piece can be flipped up from the outer edge of the bottom main body by bending only the flip-up piece upward when or after the bottom is pushed below the outer frame portion. The term "easy breaking line" used herein refers to a line that breaks when the container-holding frame sheet is deformed, and examples thereof include a perforation and a half cut.

[0009] When configured in this manner, when or after the container holding frame sheet is deformed, the pop-up pieces standing up from the bottom surround the containers stored in the storage space, thereby preventing the containers from shifting within the storage space or falling out of the storage space. Therefore, no separate jig is required, the occurrence of defective products is prevented, and there is no disruption to the subsequent food filling process.

[0010] In the sheet for container holding frames of the invention, it is preferable that the lift-up piece is attached to a corner of the polygonal bottom body, and the other longitudinal end of the leg is connected to the lift-up piece.

[0011] With this configuration, the bottom body, the lift-up pieces, and the legs can be efficiently arranged within a limited space, making it possible to make the container holding frame sheet compact.

[0012] In the sheet for container holding frames of the invention, it is preferable to adopt a configuration in which a first easy-to-fold line is formed at the boundary between the bottom body and the lift-up piece, and a second easy-to-fold line is formed at the boundary between the lift-up piece and the leg portion. Here, the easy-to-fold line refers to a line along which the container-holding frame sheet is bent when it is deformed, and examples thereof include a ruled line, a perforation, and a half-cut.

[0013] With this configuration, the boundaries between the bottom body and the lift-up piece, and between the lift-up piece and the leg portion are neatly folded, preventing assembly defects and the like.

[0014] In the container holding frame sheet of the invention, the multiple score lines or easy-to-break lines consist of multiple pairs of side lines, each pair consisting of an outer line that separates the outside of each leg from the outer frame portion and an inner line that separates the inside of each leg from the bottom portion, and the first easy-to-fold line is formed across part of the bottom portion from one inner line between adjacent pairs of side lines to the other inner line, thereby separating the bottom body and the flip-up piece, and it is preferable to adopt a configuration in which the second easy-to-fold line is extended from the other inner line to the other outer line, thereby separating the flip-up piece and the leg portion.

[0015] With this configuration, the bottom body, the lift-up pieces, and the legs can be arranged more closely and compactly.

[0016] In addition, in the sheet for container holding frames according to the present invention, it is preferable that the lift-up piece has an approximately triangular shape with three sides defined by one inner line between the adjacent side line pairs, the other outer line, and the continuous first and second easy-to-fold lines.

[0017] By configuring it in this manner, the bottom body, the lift-up piece, and the legs can be arranged efficiently, making the sheet for the container holding frame compact, and the lift-up piece can be configured to be triangular in shape, which is sufficient to prevent the container from shifting or moving.

[0018] In addition, in the sheet for a container holding frame according to the present invention, it is preferable to employ a configuration in which a third easy-fold line is provided at the boundary between the outer frame portion and the leg portion.

[0019] With this configuration, the boundary between the outer frame and the legs is neatly folded, further preventing assembly defects.

[0020] Furthermore, in the sheet for container holding frames according to the invention, it is preferable that the inner periphery of the outer frame portion and the outer periphery of the bottom portion are approximately square, and that each of the legs extends along the four sides of the inner periphery of the outer frame portion and the four sides of the outer periphery of the bottom portion, with one longitudinal end connected to a flip-up piece provided at one of the four corners of the inner periphery of the outer frame portion and the other longitudinal end connected to a flip-up piece provided at one of the four corners of the outer periphery of the bottom portion.

[0021] In this way, by assembling a sheet for a container holding frame in which the bottom body, lift-up piece, and legs are compactly arranged, it becomes easy to stably store general containers that are circular in plan view, etc. in the storage space.

[0022] In addition, in order to solve the above-mentioned problems, the container with holding frame according to the invention is configured to include a container holding frame formed by deforming the above-mentioned sheet for container holding frames, which is capable of holding a container in a storage space between the bottom and legs rising from the bottom, and a container held in the storage space.

[0023] With this configuration, the containers stored in the storage space of the container holding frame are surrounded by a pop-up piece that stands up from the bottom, preventing the containers from shifting within the storage space or falling out of the storage space.

[0024] In addition, in order to solve the above-mentioned problems, the manufacturing method of the container holding frame of the invention is configured to include a step of pushing both the bottom body and the flip-up piece of the bottom of the above-mentioned container holding frame sheet downward below the outer frame portion, and a step of pushing up only the flip-up piece of the bottom against the bottom body.

[0025] With this configuration, the sheet for the container holding frame can be easily assembled into a container holding frame that prevents the containers with the lift-up pieces from shifting when they are lifted up, simply by pushing in the bottom and pushing up the lift-up pieces.

[0026] In addition, in order to solve the above-mentioned problems, the container holding frame manufacturing apparatus of the invention is configured to include an outer frame support section that supports only the outer frame section of the above-mentioned container holding frame sheet, a push-down section that pushes down only the bottom section from the outer frame support section, and a base on which the bottom section pushed down by the push-down section comes into contact with the ground, and the base is provided with a protrusion for raising the pop-up piece of the bottom section.

[0027] When configured in this manner, by pressing the sheet for the container holding frame down to the base with the pressing-down portion, the lift-up piece is lifted up by the action of the protrusion provided on the base, making it possible to easily assemble it into a container holding frame that is less likely to cause the containers to slip out of place.

[0028] In the manufacturing device for container holding frames according to the present invention, the base may have a hole into which the bottom portion fits, and the protrusion may be provided on the edge of the hole.

[0029] When configured in this manner, the sheet for the container holding frame can be pushed down to the base and the bottom inserted into the hole, and the protrusions on the edge of the hole will automatically cause the lift-up piece to lift up, making it easier to assemble into a container holding frame. [Effects of the Invention]

[0030] Since the present invention is configured as described above, it is possible to prevent displacement and detachment of containers within the storage space of a container holding frame assembled from a sheet for a container holding frame with a simple structure.

[0032] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. The container holding frame sheet 10 of the embodiment shown in Figures 1 and 2 can be modified to assemble the container holding frame 10 of the embodiment for holding a container 20 containing food or the like.

[0033] As shown in FIGS. 1 and 2, the container holding frame sheet 10 of this embodiment is a sheet body that is generally rectangular overall, with its four corners rounded in an arc shape. The container-holding frame sheet 10 is divided into an outer frame portion 11, leg portions 12, and a bottom portion 13 by a plurality of cut lines. The material of the sheet body constituting the container holding frame sheet 10 is not particularly limited, but examples include paper, synthetic resin film, metal foil such as aluminum foil, or a composite of these, with paper being preferred as it is environmentally friendly and easy to dispose of or incinerate.

[0034] The dimensions of the sheet 10 for container-holding frames are not particularly limited, but an example would be a sheet with short sides of 100 mm to 150 mm and long sides of 150 mm to 250 mm that can hold containers 20 of general dimensions for storing food such as prepared meals, side dishes, and frozen foods when transformed into the container-holding frame 10. Note that the containers are not limited to food.

[0035] As shown in FIGS. 1 and 2, the outer frame portion 11 is made up of a rectangular ring-shaped frame main body 11a and a cross-shaped partition frame 11b. The area surrounded by the frame body 11a of the container-holding frame sheet 10 is divided by partition frames 11b into six square container-holding sections (two rows x three rows) in the front, back, left, and right directions. Each container-holding section consists of four legs 12 and one base 13.

[0036] 1 and 2, perforations 11c are formed in frame body 11a of outer frame portion 11 from the inner periphery to the outer periphery. By breaking perforations 11c, the ring of outer frame portion 11 can be opened. Furthermore, cross-shaped perforations 11d that cross the outer frame 11 in the up-down and left-right directions are formed in the partition frame 11b of the outer frame 11. At the outer edge of the outer frame 11 where the perforations 11d reach, notches 11e are formed that serve as triggers for breaking the perforations 11d. By breaking the perforations 11d, the container holding parts can be separated into individual pieces.

[0037] When the container-holding frame sheet 10 is deformed, the outer frame portion 11 becomes a framework that supports the container-holding portion. The outer dimensions of outer frame portion 11 correspond to the dimensions of container-holding frame sheet 10. The width of frame main body 11a and partition frame 11b of outer frame portion 11 is not particularly limited, but can be 3 mm to 20 mm, for example, and more preferably 8 mm to 12 mm. If the width is less than 3 mm, the strength of the outer frame portion 11 will be insufficient and there is a risk of it breaking when deformed, and if the width exceeds 20 mm, the overall dimensions of the container holding frame sheet 10 will also become larger, and there is a risk that the size of the package when packaged after deformation will also become larger accordingly.

[0038] As shown in FIGS. 1 and 2, the four legs 12 of each container holder are each formed into a long, narrow rectangle, and are arranged adjacent to each other with their longitudinal directions aligned along the four sides of the inner periphery of the outer frame 11. One end (outer end) of each leg 12 is connected to the outer frame 11. A crease 12a is formed at the boundary between the leg 12 and the outer frame 11 as a line for facilitating folding. The crease 12a extends along the inner periphery of the outer frame 11. The crease 12a allows the leg 12 to be folded relative to the outer frame 11. Furthermore, each leg portion 12 and the outer frame portion 11 are separated from each other by a linear outer line 12c, which is a cut line, except for the above-mentioned connecting portions. The outer line 12c is curved in an arc shape at the boundary between the leg portion 12 and the outer frame portion 11. This makes the leg portion 12 wider near the boundary with the outer frame portion 11, thereby reinforcing it.

[0039] When the container holding frame sheet 10 is deformed, the legs 12 support the outer periphery of the container 20 . The dimensions of the leg 12 are not particularly limited, but suitable dimensions for adequately supporting the outer periphery of a container 20, such as a side dish cup, include a length of 20 mm to 80 mm, more preferably a length of 40 mm to 50 mm, and a width of 2 mm to 15 mm, more preferably a width of 5 mm to 7 mm. If the length is less than 20 mm, the height of the container 20 when filled with food or the like will exceed this, causing it to protrude from the container holding frame 10 and potentially making it impossible to secure the container 20 within the storage space of the container holding frame 10. If the length exceeds 80 mm, the container 20 will be too tall compared to a typical container and may shift within the storage space. Furthermore, if the width is less than 2 mm, the leg portions 12 may not be strong enough and may break when deformed, and if the width exceeds 15 mm, the leg portions 12 may become too large, and when bending the boundary with the bottom portion 13 or outer frame portion 11 described below during deformation, the leg portions 12 may become too strong and may become difficult to deform, and the overall dimensions of the sheet 10 for the container holding frame may also become large, which may increase the size of the package when packaged after deformation.

[0040] As shown in FIGS. 1 and 2, the bottom 13 of each container holder is made up of a bottom body 13a and a flip-up piece 13b. The bottom body 13a has a generally square shape with the four corners cut out at an angle, and is disposed adjacent to the four legs 12 so that the four sides of the periphery thereof are aligned with the four legs 12, respectively. Lift-up pieces 13b, each shaped like an approximately right-angled isosceles triangle, are attached to the four corners of bottom body 13a so as to fill in the diagonally cut-out areas. That is, the oblique sides of lift-up pieces 13b are in contact with the oblique sides of the four corners of bottom body 13a. Lift-up pieces 13b are larger than the cut-out areas of the four corners of bottom body 13a and protrude beyond the four corners of bottom body 13a. At the boundaries between the bottom body 13a and the lift-up pieces 13b (the oblique sides of the lift-up pieces 13b and the oblique sides at the four corners of the bottom body 13a), creases 13c are formed as easy-to-fold lines. These creases 13c allow the lift-up pieces 13b to be bent relative to the bottom body 13a. Of both ends of each leg 12, the end (inner end) opposite to the side connected to the outer frame 11 is connected to the oblique side of the lift-up piece 13b of the bottom 13 that protrudes from the four corners of the bottom body 13a. In other words, the lift-up piece 13b is interposed between the bottom body 13a and the leg 12. A crease 12b is formed as an easy-to-fold line at the boundary between the leg portion 12 and the bottom portion 13. The crease 12b allows the leg portion 12 to be bent relative to the bottom portion 13. Each leg 12 and the bottom 13 are separated from each other by a straight inner line 12d, which is a cut line, except for the connecting portions. Here, the crease 13c is formed across the bottom 13 between adjacent leg portions 12, connecting the end edge of the inner line 12d of one leg portion 12 to the middle part of the inner line 12d of the other leg portion 12. Moreover, the crease 12b is formed by extending the crease 13c from the edge of the inner line 12d of one leg 12 to the outer line 12c of that leg 12. In other words, the crease 13c and the crease 12b are parallel to each other on a straight line.

[0041] When the container-holding frame sheet 10 is deformed, the bottom body 13 a of the bottom 13 supports the bottom of the container 20 . The dimensions of the corner-missing square bottom body 13a are not particularly limited, but an example of a suitable dimension for supporting the bottom of a container 20 such as a side dish cup without any excess or deficiency is one side (assuming the corners are not missing) of 20 mm to 80 mm, more preferably 30 mm to 40 mm. If the length of one side is less than 20 mm, it may be smaller than the bottom dimension of a typical container 20 and may not be able to store the container 20, and if the length of one side is more than 80 mm, it may be too large compared to the bottom dimension of a typical container 20 and the container 20 may shift or fall over within the storage space. The dimensions of the spring-up piece 13b are not particularly limited, but the oblique side may be, for example, 10 mm to 40 mm, more preferably 20 mm to 30 mm. If the length of the oblique side is less than 10 mm, the height when flipped up is small and there is a risk that the container 20 will not be held in place and will not shift, and if the length of the oblique side is more than 40 mm, there is a risk that the sheet 10 for the container holding frame will become too large.

[0042] 1 and 2, outer line 12c and inner line 12d located on both sides of each leg 12 form a pair of parallel side lines. In each container holder, there are four pairs of side lines corresponding to each leg 12. Adjacent pairs of side lines are substantially perpendicular to each other. Between two adjacent pairs of side lines, the outer line 12c of one pair of side lines is connected to the inner line 12d of the other pair of side lines to form an L-shaped break line, but the inner line 12d of one pair of side lines and the outer line 12c of the other pair of side lines are separated by the flip-up piece 13b and the inner line 12d of the other pair of side lines, and do not communicate with each other. Thus, as shown in Figures 1 and 2, in each container holding section, four L-shaped cut lines, with outer line 12c and inner line 12d connected, are arranged spaced apart, sort of like a swastika.

[0043] The configuration of the sheet 10 for a container holding frame of this embodiment has been described above. Next, a method for manufacturing the container holding frame 10 according to this embodiment will be described with reference to FIGS.

[0044] For example, first, as shown in FIGS. 3 and 4, with outer frame portion 11 of container-holding frame sheet 10 supported horizontally, bottom portion 13 of the container-holding portion is pressed downward. Then, in conjunction with this, the legs 12 of the container holding part bend downward at the ruled line 12a at the boundary with the outer frame part 11.

[0045] As the bottom 13 descends, the boundary lines 12b between the bottom 13 and the legs 12 also bend to form mountain folds when viewed from above. At this time, the bottom 13 rotates along the horizontal plane so that the positions of its four corners are misaligned with the positions of the four corners of the inner periphery of the outer frame 11. The lines 12a and 12b allow smooth folding at the boundaries between the legs 12 and the outer frame 11 or the bottom 13. In this embodiment, the lines 12a and 12b are formed in a concave shape when viewed from the top side of the container holding frame sheet 10 shown in FIG.

[0046] Simultaneously with or before or after the bottom 13 is pushed downward, only the spring-up piece 13b of the bottom 13 is pushed up against the bottom body 13a. As a result, the crease 13c is bent in a valley fold when viewed from above, and the spring-up piece 13b is spring-up (stands up) relative to the bottom body 13a.

[0047] In this way, the container holding frame 10 as shown in FIGS. 5 and 6 is completed. Between the bottom 13 and the legs 12, a three-dimensional storage space is formed that opens onto the outer frame 11, and in this storage space, as shown in the figure, a container 20 filled with frozen food or the like is stored. In this embodiment, six containers 20 are stored in six container holders. The bottom wall 21 of the container 20 rests on the bottom body 13a, and the container 20 is surrounded by the lift-up pieces 13b that stand up from all sides of the bottom body 13a, thereby preventing it from shifting or moving. Furthermore, when assembled to the container holding frame, the lift-up pieces stand up adjacent to the corners of the bottom body, making it less likely for the corners to get caught on steps or gaps on the production line, thereby reducing line stoppages and breakdowns.

[0048] In this state, the product is packaged in a packaging bag or box and then sold. A consumer who purchases this product can unwrap the package and then tear the perforations 11d formed in the partition frame 11b of the outer frame portion 11 to remove the required amount of containers 20 stored in the container holding portion. Furthermore, when it is desired to separate the container 20 from the container holding frame 10, the ring of the outer frame portion 11 can be opened and the container can be removed by breaking the perforation 11c formed in the frame body 11a of the outer frame portion 11.

[0049] The type of container 20 is not particularly limited here, but the illustration shows a container 20 such as a side dish cup, which is made by pressing a sheet of paper, synthetic resin film, metal foil such as aluminum foil, or a composite of these. This container 20 has a bottom wall 21 that is substantially circular in plan view and a peripheral wall 22 that extends up from the bottom wall 21, with pleats 22a formed on the peripheral wall 22 due to press molding. The container 20 opens upward, and can be filled with products or the like through the opening.

[0050] In this way, the folds 22a of the peripheral wall 22 of the container 20 form gear-like irregularities, so that the peripheral wall 22 engages with the leg portions 12 of the container holding frame 10 and the opening edge of the outer frame portion 11. In this way, the integrity of the container 20 is improved so that the container 20 does not fall out of the storage space of the container holding frame 10, and a container with a holding frame is constructed.

[0051] The embodiments disclosed herein are illustrative in all respects and are not restrictive. The scope of the present invention is defined by the claims, and includes all modifications within the meaning and scope of the claims.

[0052] For example, the method of transforming the sheet 10 for container-holding frames into the container-holding frames 10 is not limited to manual work as in the embodiment, but can also be automated using the manufacturing apparatus of the embodiment. One example is a jig J, as shown in Figure 7, in which the interior of a square cylindrical main body J1 is partitioned by a cross frame J2. A base B faces the bottom opening of the main body J1. A circular hole H is formed in the base B, and a protrusion L is formed on the edge of the hole. In this case, as shown in Figure 7(a), the container holding frame sheet 10 placed on the jig J is supported almost horizontally with the frame main body 11a of the outer frame portion 11 of the container holding frame sheet 10 at the upper end surface of its main body J1 and the partition frame 11b of the outer frame portion 11 at the upper end surface of its cross frame J2.

[0053] 7(a), the container 20 is placed on each container holder. In this figure, the container 20 is adsorbed by the adsorption mechanism S attached to the pusher P, and the pusher P is lowered to place the container. 7(b), the pusher P is lowered from above toward the container holding portion on which the container 20 is placed, pushing in the bottom portion 13 and legs 12 together with the container 20. The bottom portion 13 then fits into the hole H in the base B. At this time, the protrusion L on the edge of the hole H pushes up only the lift-up piece 13b of the bottom portion 13, causing it to stand up relative to the bottom body 13a. In this way, the container is transformed into the container holding frame 10. It is also possible to push in by hand without using the pusher P. The sheet 10 for container holding frames is transformed into the container holding frame 10, and the containers 20 are set in the storage space at the same time. After that, as shown in Figure 7(c), the pusher P is raised and retracted.

[0054] Of course, the same process may be carried out without placing the container 20 on the container holder, and after the container holder is transformed into the container holding frame 10, the container 20 may be set. Furthermore, after a container 20 filled with frozen food or the like is placed on the container holding portion, the bottom portion 13 can be lowered together with the food and container 20 using the pusher P in the same manner. In this case, the amount of descent of the pusher P is smaller than when nothing is placed on the container holding section or when only the container 20 is placed on it.

[0055] Alternatively, a shaft with a suction cup attached to its upper end can be raised and lowered through an opening in the bottom of jig J, and the suction cup can be attached to bottom portion 13, and then the shaft can be lowered to pull bottom portion 13 downward and deform it into container-holding frame 10. An opening can also be provided in bottom 13, and the suction cup can be attached directly to bottom wall 21 of container 20.

[0056] The shapes of outer frame 11, legs 12, bottom 13, and container holders, and the numbers of legs 12, bottom 13, and container holders are not limited to those in the embodiment. For example, as mentioned above, the bottom 13 may be provided with an opening (hole). The base 13 can also be a polygon other than a square (for example, a triangle, pentagon, or hexagon), and the number of legs 12 can be the same as the number along each side of the polygon's periphery (for example, three if the base is a triangle, five if it is a pentagon, or six if it is a hexagon). The shape of the lift-up pieces 13b is not limited to that of the embodiment, and may be a triangle or polygon other than a right-angled isosceles triangle, or may be an arc shape such as a semicircle. The position of the lift-up pieces 13b is not limited to that of the embodiment, and the legs 12 and the lift-up pieces 13b may be independently connected to the bottom body 13a, rather than being interposed between the bottom body 13a and the legs 12. The number of lift-up pieces 13b is not limited to that of the embodiment, and may be provided in pairs facing each other with the bottom body 13a in between. Furthermore, the folding of lift-up pieces 13b may be performed before or after bottom 13 is pushed downward below outer frame 11. Furthermore, container holding frame sheet 10 may be deformed and used without folding lift-up pieces 13b. This allows folding of lift-up pieces 13b at any timing on a wide variety of production lines, and allows for the selection of whether or not folding is necessary. The width of the legs 12 does not have to be constant, and they may be tapered toward the bottom 13, tapered toward the outer frame 11, or have a wavy outer edge. The outer frame 11 may be an annular shape other than a rectangular ring, such as a circular ring or a square ring. In the embodiment, six container holders are provided in two rows and three columns in the front-to-back and left-to-right directions, but it is also possible to provide three rows each in the front-to-back and left-to-right directions, or to arrange the container holders in the same number in the front-to-back and left-to-right directions.It is also possible to use only one container holder.

[0057] It is also possible to omit any of the following: crease 12a at the boundary between outer frame 11 and leg 12, crease 12b at the boundary between leg 12 and bottom 13, crease 13c at the boundary between bottom body 13a and flip-up piece 13b, perforations 11c and 11d, and notch 11e in outer frame 11. In addition, although crease 12a, crease 12b, and crease 13c are shown as examples of easy-to-fold lines in the embodiment, the invention is not limited to these, and other easy-to-fold lines such as half cuts or perforations may also be used. Instead of the outer line 12c and inner line 12d as the cut lines in the embodiment, easy-to-break lines such as half cuts or perforations may be used, which are broken when the container holding frame sheet 10 is deformed. It is preferable that the easy-to-fold line and the easy-to-break line are of different types, such as one being a half-cut and the other being a perforation, since this makes them easy to distinguish. Moreover, instead of the perforations 11c and 11d, other easily breakable lines such as half cuts may be used. The protrusions L in the manufacturing device may be provided on a flat surface instead of on the edge of the hole. [Explanation of symbols]
