Description

[Technical Field]

[0001] The present invention relates to a jig for assembling a container with a holding frame, which comprises a plurality of containers and a holding frame for holding the containers. The present invention also relates to a method for assembling a container with a holding frame using the jig. Furthermore, the present invention relates to a method for assembling a holding frame unit using the jig. [Background technology]

[0002] BACKGROUND ART Containers for storing food such as prepared dishes and side dishes, which are made by press-molding a film, paper, or the like, and which have a bottom wall and a peripheral wall rising from the bottom wall, are known. Also, as disclosed in Patent Document 1, a holding frame for holding a plurality of containers of this type is known.

[0003] The frame is assembled by deforming a single sheet with cut lines cut into it. The sheet is divided by multiple cut lines into outer frame sections arranged side by side vertically and horizontally, a bottom section surrounded by each outer frame section, and legs connecting the outer frame sections to the bottom section. 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 holding frame sheet is pushed downward below the outer frame portion, each of the legs bends downward at the boundary with the outer frame portion, resulting in a three-dimensional deformation in which multiple legs stand up from the bottom located below toward the outer frame portion located above. The container is held in the storage space thus formed between the base and the legs. The containers containing the food are then packaged in a packaging bag or the like, with a plurality of the containers held in a frame, and are then sold. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Patent No. 4988387

[0006] However, such holder frame sheets have traditionally been assembled manually, which is extremely time-consuming and has a high risk of assembly defects. If an assembly defect occurs, the completed holder frame may not be able to hold the container, or the container may be held at an angle, causing it to fall off or break during transportation. Furthermore, it was time-consuming to place the containers into the storage spaces of the assembled holding frame.

[0007] On the other hand, it is possible to create a large-scale assembly device to automate the assembling of the sheet for the holding frame and the process of placing containers into the storage space of the assembled holding frame, but this would be costly due to the complex structure, and the device would not be easy to move. Summary of the Invention [Problem to be solved by the invention]

[0008] Therefore, the problem to be solved by this invention is to provide an assembly jig for a container with a holding frame that has a simple structure, is compact, and can be configured so that it is easy to carry and does not cause any problems, making it easy to assemble the sheet for the holding frame and insert the container into the storage space. [Means for solving the problem]

[0009] To solve the above-mentioned problems, the invention provides an assembly jig for a framed container, which comprises a base and a lid. The base has a cylindrical frame that opens at least upward and a partition that divides the interior space of the frame into small compartments in a lattice pattern, with the upper edge of the frame and the upper edge of the partition forming a coplanar support surface. The lid also has a cover plate and a plurality of punches that are provided on the underside of the cover plate in one-to-one correspondence with the small compartments of the base and that fit into each of the small compartments when the cover plate is placed on the base. The retaining frame sheet is made of a single sheet body with multiple score lines or easy break lines, and is divided by the multiple score lines or easy break lines into an outer frame portion, multiple parallel bottom portions surrounded by the outer frame portion, and legs connecting the outer frame portion to each bottom portion, and the legs extend along the outer periphery of each bottom portion, with one longitudinal end connected to the outer frame portion and the other longitudinal end connected to each bottom portion.The retaining frame sheet is placed on the base so that the outer frame portion is supported on the support surface and the bottom portion faces the opening of the small chamber, and a container is placed on the bottom and the lid is placed on top of it.The bottom of the retaining frame sheet together with the container is pushed into the small chamber with the pestle, thereby deforming each of the legs downward at the boundary with the outer frame portion, and the space between the bottom and the legs rising from the bottom toward the outer frame portion becomes a storage space in which the container is held, and it can be assembled into a container with a retaining frame.

[0010] In order to solve the above-mentioned problems, the assembly jig for a framed container according to the present invention is composed of a base and a lid. The base has a cylindrical frame that is open at least upward, with the internal space of the frame forming a small chamber and the upper edge of the frame forming a support surface. The lid has a lid plate and a punch portion attached to the underside of the lid plate that fits into the small chamber when the lid plate is placed on the base. The retaining frame sheet is made 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, a bottom portion surrounded by the outer frame portion, and legs connecting the outer frame portion and the bottom portion, and the legs extend 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.The retaining frame sheet is placed on the base so that the outer frame portion is supported on the support surface and the bottom faces the opening of the small chamber, and a container is placed on the bottom and the lid is placed on top of it.The bottom of the retaining frame sheet, together with the container, is pushed into the small chamber with the pestle, causing each of the legs to deform downward at the boundary with the outer frame portion, and the space between the bottom and the legs rising from the bottom toward the outer frame portion becomes a storage space in which the container is held, and it can be assembled into a container with a retaining frame.

[0011] By configuring it in this way, assembly becomes much easier than assembling a container with a holding frame by hand, and assembly defects are less likely to occur. The assembly jig has a simple structure and can be configured compactly, so it can reduce costs compared to large-scale assembly equipment and is easy to carry. Furthermore, by using the jig according to the present invention, it is also possible to assemble the sheet for the holder frame into a container holder frame by itself, without placing the container on the sheet for the holder frame.

[0012] In the assembly jig for a framed container according to the present invention, it is preferable that the base further includes a guide plate that is connected to the outer surface of at least one of the four sides of the frame and is higher than the frame.

[0013] With this configuration, the holding frame sheet is positioned on the guide plate, making it easy to place the outer frame portion on the support surface and the bottom portion on the opening of the small room without any misalignment.

[0014] In the assembly jig for a container with a holding frame according to the invention, the guide plates can be provided on all four sides of the frame, and the guide plate provided on the front side can be lower than the guide plate provided on the back side.

[0015] The guide plates position the holding frame sheet from all four sides, further preventing misalignment. By making the height of the guide plate on the front lower than that of the guide plate on the back, the guide plate on the front does not get in the way when placing the holding frame sheet on the base from the front, allowing for smooth operation. The guide plate on the back is higher, so there is no risk of accidentally placing the holding frame sheet on top of it.

[0016] In the assembly jig for a framed container according to the present invention, the base preferably has a finger-insertion notch on the upper edge of the frame.

[0017] With this configuration, by placing the lid on the base and pushing the lid in, even if the base and the lid are in close contact after the assembly work is completed, the lid can be easily lifted from the base by inserting a finger into the cutout, thereby improving work efficiency.

[0018] In the assembly jig for a container with a retaining frame according to the invention, the notch is provided on the upper edge of at least the left and right side surfaces of the frame body, and the frame body further includes a guide plate that is connected to the outer surface of at least the left and right side surfaces of the four faces and is higher than the frame body, and the notch and the guide plate are arranged so as not to overlap each other.

[0019] With this configuration, the guide plate positions the holding frame sheet at least from the left and right, preventing misalignment, including in the left and right directions. Because the guide plate and the notch are positioned so that they do not overlap, the guide plate does not interfere with the operation of inserting a finger into the notch to lift the lid.

[0020] In the assembly jig for a container with a holding frame according to the invention, the guide plate can be divided into sections in front of and behind the notch, and the divided guide plate in front of the notch can be lower than the divided guide plate behind the notch.

[0021] This simple configuration prevents the guide plates from overlapping with the notches. Furthermore, because the divided guide plate in front of the notch is lower than the divided guide plate behind the notch, the left and right guide plates do not get in the way when placing the sheet for the holding frame on the base from the front, allowing for smooth operation. Because the divided guide plate behind the notch is higher, the sheet for the holding frame will not accidentally be placed on top of it.

[0022] In the assembling jig for a framed container according to the present invention, the frame body can be closed at the bottom, but it is preferable to adopt a configuration in which it is open not only at the top but also at the bottom.

[0023] With this configuration, when the lid is placed over the base and the pestle part is pushed into the small chamber, the air inside the small chamber escapes appropriately through the opening at the bottom, so air resistance is not large and the pushing operation can be carried out smoothly without requiring force.

[0024] In the assembling jig for a container with a holding frame according to the present invention, the punch portion of the lid may be prismatic, but is preferably cylindrical.

[0025] With this configuration, the pestle portion has a rounded peripheral surface, so it will not get caught on the holding frame sheet or base, allowing for smooth operation.

[0026] In the assembly jig for a framed container according to the present invention, it is preferable that the lid further has a handle connected to the top surface of the lid plate.

[0027] With this configuration, the lid can be easily handled and operated by gripping the handle, allowing for smoother operation.

[0028] In the assembly jig for a container with a holding frame according to the present invention, the cover plate and the pestle portion of the lid can be fixed inseparably or integrated, but it is preferable to adopt a configuration in which they are detachable.

[0029] With this configuration, if a particular punch part becomes worn or damaged during operation, only that punch part can be replaced instead of the entire lid, thereby reducing replacement costs.

[0030] In the assembly jig for a container with a holding frame according to the present invention, the lid and the base may be opaque, but it is preferable to adopt a configuration in which at least the lid plate of the lid and at least the frame and partition of the base are transparent.

[0031] With this configuration, the state of the holding frame can be visually checked through the cover plate, frame body, and partition during the assembling work of the holding frame, making it easy to make fine adjustments such as fine adjustments of the pushing force during the process to prevent assembly failure.

[0032] In the assembling jig for a framed container according to the present invention, it is preferable to employ a configuration consisting of only the lid and the base.

[0033] By using the minimum necessary configuration in this way, it can be made into an optimal assembly jig that is simple, compact, and easy to carry.

[0034] In addition, in order to solve the above-mentioned problems, the assembly method (manufacturing method) of the container with a retaining frame of the invention is configured to include the steps of preparing a sheet for the retaining frame, placing the sheet for the retaining frame on the base of the assembly jig for the container with a retaining frame of the invention so that the outer frame portion is supported on the support surface and the bottom faces the opening of the small chamber, placing the container on top so that it matches the bottom, and placing the lid on top so that the pestle portion matches the bottom, and using the pestle portion to push the bottom together with the container into the small chamber, thereby deforming each of the legs downward at the boundary with the outer frame portion, and assembling the container into a container with a retaining frame in which the container is held in the storage space between the bottom and the legs.

[0035] By configuring it in this way, assembly becomes much easier than assembling a container with a holding frame by hand, and assembly defects are less likely to occur.

[0036] In addition, in order to solve the above-mentioned problems, the assembly method (manufacturing method) of the holding frame of the invention is configured to include the steps of preparing a sheet for the holding frame, placing the sheet for the holding frame on the base of the assembly jig for a container with a holding frame of the invention so that the outer frame portion is supported on the support surface and the bottom portion faces the opening of the small chamber, and then, without placing a container on the bottom, placing the lid on top so that the pestle portion matches the bottom, and using the pestle portion to directly push the bottom portion into the small chamber, thereby deforming each of the legs downward at the boundary with the outer frame portion, and assembling it into a container holding frame in which a storage space is formed between the bottom and the legs.

[0037] By configuring it in this way, even when using an assembly jig for a container with a holding frame, it is possible to assemble the holding frame sheet alone into the holding frame without placing a container on the holding frame sheet. [Effects of the Invention]

[0038] The assembly jig for containers with holding frames according to the invention has been configured as described above, and the assembly method for containers with holding frames according to the invention has been configured as described above, so that the assembly jig has a simple structure and a compact configuration that does not cause problems with portability, making it possible to easily assemble the sheet for the holding frame and insert the container into the storage space.

[0040] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. The assembly jig 1 of the embodiment shown in Figures 1 to 3 is used to assemble the retaining frame sheet shown in Figure 4 together with a container into a container with a retaining frame shown in Figure 9 through the assembly method of the embodiment shown in Figures 5 to 8. The assembly jig 1 of the embodiment comprises a base 10 shown in FIG. 2 and a lid 20 shown in FIG.

[0041] As shown in FIGS. 1 and 2, the base 10 is made up of a frame 11, a partition 12, and a guide plate 13. The frame 11 has a rectangular cylindrical shape with four sides: a front surface 11a, a rear surface 11b, and left and right side surfaces 11c, and is open at both the top and bottom. Semicircular cutouts 11d are provided on the upper edges of the left and right side surfaces 11c of the frame 11. The cutouts 11d are large enough to fit a finger. The length of the frame 11 in the left-right direction is greater than the length in the front-rear direction, being approximately 1.5 times as long. The material of the frame 11 is not particularly limited, and examples include synthetic resin, metal, and wood, but acrylic is preferable because it has high transparency and strength. In this embodiment, the frame 11 is made of acrylic and is transparent.

[0042] 1 and 2, the partition 12 is configured by partition plates arranged vertically and horizontally, and divides the space inside the frame body 11 into a plurality of small rooms 12a. The partition 12 is fixed to the frame body 11 by an appropriate means such as adhesive. The small rooms 12a, which are open in the vertical direction, are approximately square in plan view, and although there is no particular limit to the number of rooms, in this embodiment, there are three rows in the left-right direction of the frame body 11 and two rows in the front-to-back direction, for a total of six rooms.

[0043] 1 and 2, the height of the partition 12 is the same as the height of the frame body 11, and the upper edge of the partition 12 and the upper edge of the frame body 11 are on the same plane, forming support surfaces 11e and 12b. The retaining frame sheet is placed on these support surfaces 11e and 12b. The material of the partition 12 is not particularly limited, and examples include synthetic resin, metal, and wood, but acrylic is preferable because it has high transparency and strength. In this embodiment, the partition 12 is made of acrylic and is transparent.

[0044] As shown in FIGS. 1 and 2, the guide plates 13 are fixed to the outer surfaces of the front surface 11a, rear surface 11b, and left and right side surfaces 11c of the frame body 11 by suitable means such as adhesive. The height of guide plate 13 is greater than the height of frame body 11. Therefore, a step is formed between support surfaces 11e, 12b and the upper edge of guide plate 13, and guide plate 13 guides the holding frame sheet placed on support surfaces 11e, 12b so that it does not shift back and forth or side to side. The guide plate 13 consists of a front guide 13a, a rear guide 13b, and left and right guides 13c, with the front guide 13a being lower than the rear guide 13b, so that the front guide 13a does not get in the way when attempting to place the holding frame sheet on the support surfaces 11e and 12b from the front side of the assembly jig.

[0045] 1 and 2, the left and right guides 13c are divided into front and rear sections by the cutouts 11d provided in the left and right side surfaces 11c of the frame body 11. This prevents the left and right guides 13c from overlapping the cutouts 11d and from getting in the way when inserting a finger into the cutouts 11d. The left and right guides 13c are divided into front and rear halves, with the front half having the same height as the front guide 13a and the rear half having the same height as the rear guide 13b. In other words, the front half is lower than the rear half. This prevents the front half of the left and right guides 13c from getting in the way when attempting to place the retaining frame sheet on the support surfaces 11e and 12b from the front side of the assembly jig. The material of the guide plate 13 is not particularly limited, and examples include synthetic resin, metal, and wood, but acrylic is preferable because it has high transparency and strength. In this embodiment, the guide plate 13 is made of acrylic and is transparent.

[0046] As shown in FIGS. 1 and 3, the lid 20 is made up of a lid plate 21, a pestle part 22, and a handle . The cover plate 21 is rectangular, and its length in the left-right and front-rear directions is approximately equal to that of the frame body 11, so that when the cover plate 21 is placed on the frame body 11, one side does not protrude beyond the other. The thickness of the cover plate 21 is not particularly limited, but in this embodiment, it is set to be approximately equal to the size of the step between the upper edge of the frame body 11 of the base 10 and the front half of the front guide 13a and the left and right guides 13c. As a result, when the cover plate 21 is placed on the frame body 11, the top surface of the cover plate 21 and the upper edges of the front half of the front guide 13a and the left and right guides 13c form the same plane. The material of the cover plate 21 is not particularly limited, and examples include synthetic resin, metal, and wood, but acrylic is preferable because it has high transparency and strength. In this embodiment, the cover plate 21 is made of acrylic and is transparent.

[0047] 1 and 3, the multiple punches 22 are cylindrical and are attached to the underside of the cover plate 21. The intervals between adjacent punches 22 are equal, and the number of punches 22 is not particularly limited, but in this embodiment, a total of six punches 22 are arranged side by side in three rows in the left-right direction and two rows in the front-rear direction of the cover plate 21. That is, there is a one-to-one correspondence between the punches 22 and the small chambers 12a of the base 10. When the lid 20 is placed on the base 10, each punch 22 is housed in its corresponding small chamber 12a of the base 10. The pestle portion 22 presses a portion of the container or holding frame sheet placed on the base 10 into the small chamber 12a when the lid 20 is placed on the base 10. As described above, the pestle portion 22 has a cylindrical shape, and therefore the outer surface is rounded so as not to damage the container or holding frame sheet.

[0048] 1, the punch part 22 has a threaded hole 22a on its top surface that extends in the axial direction of the cylinder, and is detachably attached to the cover plate 21 by being screwed with a knob bolt 22b that passes through the cover plate 21. Therefore, if the punch part 22 becomes worn or damaged, the knob bolt 22b can be rotated to loosen the connection, and the punch part 22 can be removed from the cover plate 21 and replaced with a new punch part 22. The material of the punch part 22 is not particularly limited, and examples include synthetic resin, metal, and wood, but it is preferably made of a relatively soft and slippery synthetic resin so as not to damage the retaining frame sheet. In this embodiment, the punch part 22 is made of monomer cast nylon, which is a material different from acrylic, and is opaque. The dimensions of the pestle portion 22 are not particularly limited, but in this embodiment, its outer diameter is approximately half the length of the small chamber 12a in the front-to-back and left-to-right directions, and its axial length is approximately half the length of the small chamber 12a in the up-to-down direction.

[0049] As shown in FIGS. 1 and 3, the handle 23 has a horizontal U-shape, and both ends thereof are fixed to the upper surface of the cover plate 21 by appropriate means such as bolts. The lid 20 can be easily operated by gripping the handle 23. The material of the handle 23 is not particularly limited, and examples include synthetic resin, metal, and wood, but a relatively hard synthetic resin is preferable for its high strength. In this embodiment, the handle 23 is made of monomer cast nylon, which is a material different from acrylic, and is opaque.

[0050] There are no limitations on the type of holder frame sheet, but an example is shown in Figure 4. In Figure 4, holder frame sheet 30 is a sheet body that is approximately square overall, with its four corners rounded in an arc shape. The holding frame sheet 30 is divided into an outer frame portion 31, leg portions 32, and a bottom portion 33 by making a plurality of cut lines.

[0051] As shown in FIG. 4, the outer frame portion 31 is made up of a square annular frame main body 31a and a cross-shaped partition frame 31b. The area surrounded by frame body 31a of holder frame sheet 30 is divided by partition frames 31b into six square container holders, three in the front-to-back direction and two in the left-to-right direction. Each container holder consists of four legs 32 and one base 33.

[0052] 4, perforations 31c extending from the inner periphery to the outer periphery are formed at the four corners of the frame body 31a of the outer frame portion 31. By breaking these perforations 31c, the ring of the outer frame portion 31 can be opened. Furthermore, cross-shaped perforations 31d that cross the outer frame 31 in the up-down and left-right directions are formed in the partition frame 31b of the outer frame 31. At the outer edge of the outer frame 31 where the perforations 31d reach, notches 31e are formed that serve as triggers for breaking the perforations 31d. By breaking the perforations 31d, the container holding parts can be separated into individual pieces. When the holding frame sheet 30 is deformed, the outer frame portion 31 becomes a framework that supports the container holding portion.

[0053] As shown in FIG. 4, the four legs 32 of each container holder are each formed into a long, narrow rectangle, and are arranged adjacent to each other so that their longitudinal directions run along the four sides of the inner periphery of the outer frame 31. Of both ends of each leg portion 32, one end (outer end) is connected to the outer frame portion 31. A crease 32a is formed at the boundary between the leg portion 32 and the outer frame portion 31 as a line for facilitating folding. The crease 32a extends along the inner periphery of the outer frame portion 31. The crease 32a allows the leg portion 32 to be folded relative to the outer frame portion 31. Furthermore, each leg portion 32 and the outer frame portion 31 are separated from each other by a linear outer line 32c, which is a cut line, except for the above-mentioned connecting portions. The outer line 32c is curved in an arc shape at the boundary between the leg portion 32 and the outer frame portion 31. This widens the leg portion 32 near the boundary with the outer frame portion 31, thereby reinforcing it. When the retaining frame sheet 30 is deformed, the legs 32 support the outer periphery of the container 40 .

[0054] As shown in FIG. 4, the bottom 33 of each container holder is substantially square, and the four sides of the periphery are arranged adjacent to the four legs 32 so as to be aligned along the four legs 32, respectively. Of both ends of each leg portion 32, the end (inner end) opposite the side connected to the outer frame portion 31 is connected to the bottom portion 33. A crease 32b is formed at the boundary between the leg portion 32 and the bottom portion 33 as a line for easy folding. This crease 32b allows the leg portion 32 to be folded relative to the bottom portion 33. Each leg 32 and the bottom 33 are separated from each other by a straight inner line 32d, which is a cut line, except for the connecting portions. When the retaining frame sheet 30 is deformed, the bottom portion 33 supports the bottom of the container 40 .

[0055] As shown in Figure 4, the outer line 32c and the inner line 32d located on both sides of each leg 32 form a pair of parallel side lines. In each container holder, there are four pairs of side lines, one for each leg 32. Adjacent pairs of side lines are substantially perpendicular to each other. Between two adjacent pairs of lateral lines, the outer line 32c of one pair of lateral lines is connected to the inner line 32d of the other pair of lateral lines to form an L-shaped break line, but the inner line 32d of one pair of lateral lines and the outer line 32c of the other pair of lateral lines are separated by the inner line 32d of the other pair of lateral lines and do not communicate with each other. Thus, as shown in FIG. 4, in each container holding portion, four L-shaped cut lines, each connecting outer line 32c and inner line 32d, are arranged spaced apart, sort of like a swastika. The boundary line 32b between the leg 32 and the bottom 33 is formed diagonally across the corner of the bottom 33 from the end of the inner line 32d of one pair of adjacent side lines to the middle of the inner line 32d of the other pair of side lines.

[0056] The type of container 40 is not particularly limited, but Figures 6 and 7 show an example of a container 40 called 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 40 has a bottom wall 41 that is substantially circular in plan view and a peripheral wall 42 that extends up from the bottom wall 41, with pleats 42a formed on the peripheral wall 42 due to press molding. The container 40 opens upward, and can be filled with products or the like through the opening.

[0057] In this way, the circumferential wall 42 of the container 40 has gear-like irregularities formed by the folds 42a, and therefore engages with the leg parts 32 of the container holding frame and the opening edge of the outer frame part 31. In this way, the integrity of the container 40 is improved so that it does not fall out of the storage space of the container holding frame.

[0058] The configuration of the assembly jig 1 of the embodiment and the configurations of the retaining frame sheet 30 and container 40 assembled using the jig are as described above. Next, with reference to Figures 5 to 9, we will explain the method of assembling the retaining frame-equipped container of the embodiment.

[0059] First, as shown in Figure 5, the horizontally supported retaining frame sheet 30 is placed on the base 10 of the assembly jig 1. The retaining frame sheet 30 is positioned by the guide plate 13 so that its outer frame portion 31 is supported by the support surfaces 11e and 12b and its bottom portion 33 faces the upper opening of each small chamber 12a.

[0060] Next, as shown in FIG. 6, the containers 40 are placed on the bottom portions 33 of the holding frame sheets 30, respectively. When the container 40 is placed, its bottom wall 41 is in contact with and supported by the bottom portion 33.

[0061] Once the container 40 has been placed, as shown in Figures 7 and 8, the lid 20 is placed on the base 10, and the bottom 33 of the retaining frame sheet 30, together with the bottom wall 41 of the container 40, is pushed toward the small chamber 12a below using the pestle portion 22 of the lid 20. Then, in conjunction with this, the legs 32 bend downward at the ruled lines 32a that are the boundaries with the outer frame 31.

[0062] As the bottom 33 descends, the boundary lines 32b between the bottom 33 and the legs 32 also bend to form mountain folds when viewed from above. At this time, the bottom 33 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 31. The container 40 descends together with the bottom 33 and is stored in the storage space defined by the bottom 33 and the legs 32 rising from the bottom 33. Here, as shown in Figures 8(b) and 8(c), the container 40 is first pushed open so that the peripheral wall 42 collapses, and then rises to its original state due to its restoring elasticity, and the upper edge of the peripheral wall 42 engages with the outer frame portion 31, thereby fixing it to the container holding frame.

[0063] From this point, when the lid 20 is raised as shown in FIG. 9, the container with the holding frame is completed, and it can be removed from the assembly jig 1 as shown in FIG. By using the assembly jig 1, assembly becomes much easier than when assembling a container with a holding frame by hand, and assembly defects are less likely to occur. The assembly jig 1 consists of only a base 10 and a lid 20, and has a simple structure and is compact, so it can be manufactured at a lower cost than large-scale assembly equipment and is easy to carry.

[0064] The container 40 is filled with food in advance, or the food is filled after the container with the holding frame is completed, and the container is then packaged in a packaging bag or box in that state and then offered for sale. A consumer who purchases this product can unwrap the packaging and then tear the perforation 31d formed in the partition frame 31b of the outer frame portion 31 to remove the required amount of containers 40 stored in the container holding portion. Furthermore, when it is desired to separate the container 40 from the container holding frame, the ring of the outer frame portion 31 can be opened and the container can be removed by breaking the perforation 31c formed in the frame body 31a of the outer frame portion 31.

[0065] 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.

[0066] The assembly jig 1 of the embodiment is configured to assemble a sheet for a holding frame that forms a storage space of 3 rows x 2 rows when assembled, with the small chambers 12a and pestle portions 22 arranged in parallel in 3 rows x 2 rows, but the number of parallel rows is not limited to this. Also, the partition 12 may be eliminated, and the internal space of the frame 11 may be made into a single small room, in which case the punch portion 22 of the lid 20 may also be made correspondingly single. In this case, only the upper edge of the frame 11 forms the support surface 11e. In this case, the holding frame sheet also has a single bottom 33 and a single storage space formed by the bottom 33 and legs 32 after assembly. Furthermore, although the small compartments separated by the partition 12 are rectangular, they are not limited to rectangular shapes and can also be other shapes (for example, polygons such as triangles and pentagons, circles, ellipses, etc.) depending on the shape of the outer frame portion of the holding frame sheet. Furthermore, the assembly jig 1 of the embodiment has a simple structure and is made up of only the base 10 and the lid 20, but other components may also be added.

[0067] In the assembling method of the embodiment, the holder frame sheet 30 is assembled together with the container 40, but it is also possible to assemble the holder frame sheet 30 alone. That is, the method for assembling the holding frame of the embodiment using the assembly jig 1 of the embodiment omits the step of placing the container 40 on the bottom 33 of the holding frame sheet 30 from the steps of the method for assembling a container with a holding frame of the embodiment described above. Then, in a subsequent step, the bottom 33 of the holding frame sheet 30 is pressed directly toward the small chamber 12a below by the pestle portion 22 of the lid 20, without going through the bottom wall 41 of the container 40. As a result, a storage space is formed between the bottom 33 and the legs 32 rising from the bottom 33, and the container holding frame is assembled. When the holding frame sheet 30 is assembled alone, it becomes possible to store food and other contents directly or individually packaged food and other contents in the storage space of the assembled holding frame sheet 30. In addition, the contents are not limited to food and can include a variety of items.

[0068] The shape of the retaining frame sheet assembled by the assembly jig 1 of the embodiment is not limited to that shown in the embodiment. The retaining frame sheet is made of a single sheet body with multiple score lines or easy break lines, and is divided by the multiple score lines or easy break lines into an outer frame, a bottom surrounded by the outer frame, and legs connecting the outer frame and the bottom, and the legs extend along the periphery of the bottom, with one longitudinal end connected to the outer frame and the other longitudinal end connected to the bottom, and the number of legs, the shape of the bottom, the number of parallel container storage sections, etc. are not limited to the embodiments. For example, it is possible to have two legs, a circular bottom, or two rows of parallel container storage sections. In addition, although in the embodiment, each of the legs is bent downward at the boundary with the outer frame, it is also possible to deform the legs without bending them. For example, it is possible to deform each of the legs downward by curving them without bending them to form a storage space. Similarly, in the embodiment, each of the legs is bent relative to the bottom, but it is also possible to deform the legs without bending them. For example, it is possible to deform each of the legs relative to the bottom by curving them without bending them to form a storage space. [Explanation of symbols]
