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 extends in an arc shape along an outer periphery of the bottom part in a round shape, whose one end in a longitudinal direction is connected to the outer frame part and whose other end in the longitudinal direction is connected to the bottom part. When the bottom part is pressed downward more than the outer frame part, the bottom part folds downward at a boundary between the leg part 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 and the leg part. In a case where the container has a general shape in which a bottom wall is round and a peripheral wall expands conically from the bottom wall, when the sheet is deformed into a container holding frame, the bottom part in the storage space has a shape following a shape of the bottom wall of the container and an outer periphery of the storage space constituted of the leg part has a shape following a shape of the peripheral wall of the container, which can further suppress the container from staggering in the storage space and from being detached out of the storage space.SELECTED DRAWING: Figure 3

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. [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, with one longitudinal end connected to the outer frame portion and the other longitudinal end connected to the bottom, and when the bottom of the 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 outer periphery of the bottom is configured to be approximately circular. 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] With this configuration, if a container with a typical shape in which the bottom wall is circular and the surrounding wall expands conically from there is used, the shape of the bottom of the storage space will follow the shape of the bottom wall of the container, thereby preventing the container 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. The bottom portion only needs to have a substantially circular outer periphery, and the overall shape may be, for example, a circular ring shape with an opening such as a round hole provided in the center of the bottom portion.

[0010] In the sheet for a container holding frame according to the present invention, it is preferable that each of the legs is curved in an arc so as to fit along the outer periphery of the bottom.

[0011] With this configuration, if a container with a typical shape in which the bottom wall is circular and the peripheral wall expands conically from there is used, when the container is deformed into a container holding frame, the shape of the outer periphery of the storage space will follow the shape of the peripheral wall of the container, further preventing the container 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.

[0012] In the container holding frame sheet of the invention, the multiple score lines or fragile 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 and an inner line that separates the inside of each leg from the bottom, and between adjacent pairs of side lines, one inner line is extended as is to become the other outer line, and it is preferable to adopt a configuration in which the multiple legs are arranged in a spiral pattern in parallel around the circumferential direction of the bottom.

[0013] With this configuration, the arc-shaped legs can be arranged closely together around the circumference of the circular bottom, allowing for a larger number of legs to be used, so that when the container is transformed into a container-holding frame, the containers in the storage space are closely surrounded by the many legs in the circumferential direction, improving the holding performance and further preventing the containers from shifting.

[0014] In the sheet for container holding frames of the invention, it is preferable that the legs are arranged at equal intervals around the periphery of the bottom, and when the sheet is deformed into a container holding frame, the boundary between the outer frame and the legs bends, and the fold line and the pair of side lines form a gear-shaped engaging portion on the inner circumference of the outer frame with which the upper edge of the container can mesh.

[0015] With this configuration, the upper edge engages with the engaging portion, positioning the container, further preventing it from shifting within the storage space.

[0016] In the sheet for container holding frames of the invention, it is preferable that multiple bottoms are formed in parallel and that the spiral curvature directions of the legs of adjacent bottoms are opposite to each other.

[0017] By configuring it in this way, when the sheet for the container holding frame is deformed to form a container with a holding frame and packaged in a packaging bag, the spiral directions on both sides can be aligned so as not to get caught on both ends of the opening of the packaging bag.

[0018] In the sheet for a container holding frame according to the present invention, it is preferable to adopt a configuration in which the number of legs arranged in parallel along the outer periphery of one bottom portion is five or more.

[0019] Conventional container holding frames such as that shown in Patent Document 1 have a maximum of about four legs, but with this configuration, the greater number of legs allows the container to be more tightly surrounded and held when assembled to the container holding frame, making it ideal for preventing the container from shifting or moving within the storage space.

[0020] In the container holding frame sheet according to the present invention, it is preferable to employ a configuration in which easy-fold lines are provided at the boundary between the bottom portion and the leg portions, and at the boundary between the outer frame portion and the leg portions. 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.

[0021] With this configuration, when the container-holding frame sheet is deformed, the boundary between the bottom and the legs, and the boundary between the outer frame and the legs, are neatly folded, preventing assembly defects and the like.

[0022] 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 circular, and that each of the legs extends along the inner periphery of the outer frame portion and the outer periphery of the bottom portion, with one longitudinal end connected to the inner periphery of the outer frame portion and the other longitudinal end connected to the outer periphery of the bottom portion.

[0023] With this configuration, it becomes easy to stably store typical containers that are circular in plan view in the storage space, and because the configuration is relatively simple, it becomes relatively easy to adjust the number and density of the legs as appropriate.

[0024] 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. [Effects of the Invention]

[0025] 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.

[0027] 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.

[0028] 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.

[0029] 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.

[0030] 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 approximately circular container-holding sections (two rows x three rows in the front, back, left, and right directions). Each container-holding section consists of six legs 12 and one base 13.

[0031] 1, 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 to serve as triggers for breaking the perforations 11d. By breaking the perforations 11d, the container holding parts can be separated into individual pieces.

[0032] 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. There are no particular limitations on the width of frame body 11a and partition frame 11b of outer frame portion 11, but the minimum width can be, for example, 3 mm to 20 mm, and more preferably, 8 mm to 12 mm. If the minimum 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 minimum width is more than 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.

[0033] As shown in FIGS. 1 and 2, the six legs 12 of each container holder are each shaped like an elongated arc, and are arranged adjacent to each other with their longitudinal directions aligned along 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 easy folding. This 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 an arc-shaped outer line 12c, which is a cut line, except for the above-mentioned connecting portions.

[0034] 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. However, the above dimensions may be appropriately set depending on the dimensions of the container 20 to be accommodated, and are not limited to the above-mentioned dimensional ranges.

[0035] As shown in FIGS. 1 and 2, bottom portion 13 of each container holder has a substantially circular shape, and is disposed adjacent to six leg portions 12 at equal intervals so that its outer periphery follows along the six leg portions 12. Of both ends of each leg portion 12, the end (inner end) opposite the side connected to the outer frame portion 11 is connected to the bottom portion 13. A crease 12b is formed at the boundary between the leg portion 12 and the bottom portion 13 as a line for easy folding. This crease 12b allows the leg portion 12 to be folded relative to the bottom portion 13. Each leg 12 and the bottom 13 are separated from each other by an arc-shaped inner line 12d, which is a cut line, except for the above-mentioned connecting portion.

[0036] When the container-holding frame sheet 10 is deformed, the bottom portion 13 supports the bottom of the container 20 . The dimensions of the bottom 13 are not particularly limited, but examples of dimensions suitable for adequately supporting the bottom of a container 20, such as a side dish cup, include a diameter of 20 mm to 80 mm, and more preferably 30 mm to 40 mm. If the diameter is less than 20 mm, it may be smaller than the bottom dimensions of a typical container 20 and may not be able to store the container 20, and if the diameter is more than 80 mm, it may be too large compared to the bottom dimensions of a typical container 20 and may cause the container 20 to shift or fall over within the storage space.

[0037] 1 and 2, the arc-shaped outer line 12c and inner line 12d located on both sides of each leg 12 form a pair of approximately parallel side lines. In each container holder, there are six pairs of side lines, one for each leg 12. Between two adjacent pairs of side lines, the outer line 12c of one pair of side lines is extended in an arc shape to become the inner line 12d of the other pair of side lines. The inner line 12d of one pair of side lines and the outer line 12c of the other pair of side lines are spaced apart and generally parallel to each other, with the outer line 12c of one pair of side lines and the inner line 12d of the other pair of side lines sandwiched between them, and are not connected to each other.

[0038] Thus, as shown in FIGS. 1 and 2, the cut lines are arranged in a spiral shape, with six pairs of side lines arranged in parallel along the outer periphery of the bottom portion 13. As shown in Figure 1, the spiral direction is opposite between two container holding sections that are aligned in the short side direction of the sheet 10 for a container-holding frame. Also, the spiral direction is opposite between two container holding sections and one container holding section among three container holding sections that are aligned in the long side direction of the sheet 10 for a container-holding frame.

[0039] The configuration of the sheet 10 for a container holding frame of this embodiment has been described above. Next, an example of a method of transforming the sheet 10 into a container holding frame 10 (assembly method) will be described with reference to FIGS.

[0040] For example, first, with outer frame portion 11 of container-holding frame sheet 10 supported horizontally, bottom portion 13 of the container-holding portion is pressed downward as shown in FIG. Then, as shown in the figure, the legs 12 of the container holder are linked to this and bend downward at the ruled line 12a at the boundary with the outer frame 11.

[0041] As the bottom 13 descends, the boundary line 12b between the bottom 13 and the leg 12 also bends to form a mountain fold when viewed from above. At this time, the bottom 13 rotates along the horizontal plane while descending. The lines 12a and 12b allow the folding operation at the boundaries between the legs 12 and the outer frame 11 or the bottom 13 to be carried out smoothly.

[0042] As shown in Fig. 3, a gear-shaped engaging portion is formed on the opening edge of the container holding portion (the inner periphery of the outer frame portion). In addition, the container 20 is held by the container holding frame 10 with each leg portion 12 rising obliquely from the bottom portion 13 toward the outer frame portion 11 and fitting along the side surface of the container 20. As a result, the gear-shaped engaging portion on the opening edge of the container holding portion (inner circumference of the outer frame portion) engages with the upper edge of the container 20, thereby positioning the container and stabilizing the storage state.However, even if the engagement between the engaging portion and the upper edge of the container 20 is incomplete, each leg 12 holds the container 20 in a state where it is obliquely aligned with the side of the container 20, so the storage state of the container 20 will still be maintained stably. Between the bottom 13 and the legs 12, a three-dimensional storage space is formed that opens onto the outer frame 11, and a container 20 filled with frozen food or the like is stored in this storage space, as shown by the arrow in Figure 3. In this way, the container holding frame 10 is completed as shown in FIGS. In this embodiment, six containers 20 are stored in six container holders.

[0043] 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.

[0044] Here, the type of container 20 is not particularly limited, but Figures 3 to 5 show an example of a container 20 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 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.

[0045] In this way, the peripheral wall 22 of the container 20 has gear-like irregularities formed by the folds 22a, and therefore engages with the gear-shaped engaging portion of the container holding frame 10 described above. In this way, the container with the holding frame is constructed with enhanced integrity so that the container 20 will not fall out of the storage space of the container holding frame 10. Furthermore, as described above, even if the engagement between the engaging portions and the upper edge of the container 20 is incomplete, the container 20 is held in a state in which each leg 12 is obliquely aligned with the side surface of the container 20, so that the storage state of the container 20 is still maintained stably.

[0046] Furthermore, because the bottom 13 is generally circular, it is less likely to get caught on steps or gaps in the production line compared to a bottom with an angular shape, and because each leg 12 is arc-shaped, it is less likely to get caught on steps or gaps in the production line. Furthermore, by configuring the spiral curve of the legs 12 to be in opposite directions between adjacent bottoms, it is possible to align the spiral direction on both sides so that it does not go against the flow of the production line. As a result, it is possible to sufficiently prevent the framed container from getting caught on equipment in the production line, thereby preventing production line stoppages and malfunctions.

[0047] It is also possible to store the container 20 after the container holder is transformed into the container holding frame 10 without placing the container 20 on it. However, if this is done, depending on the characteristics of the material constituting the container holding frame 10, after it has been deformed and before the container 20 is stored, a repulsive force will act to return it to its original sheet shape, and the deformed state of the container holding frame 10 may not be maintained. Therefore, the following method can be exemplified as a method for maintaining the deformed state of the container-holding frame 10 before the containers 20 are stored. For example, when the container-holding frame 10 is deformed, the bottom 13 moves down and rotates along the horizontal plane as it deforms, but after the container-holding frame 10 is deformed to a deformed state in which the distance between the outer frame 11 and the bottom 13 is at its maximum (maximum deformed state), the bottom 13 can be forcibly rotated further in the same direction of rotation, thereby making it possible to maintain the deformed state of the container-holding frame 10. Specifically, when the bottom 13 is rotated in this manner, the bending angle at the boundary between the bottom 13 and the legs 12 becomes larger than the angle (approximately 90°) in the maximum deformation state, and as a result, the bending direction at the boundary between the bottom 13 and the legs 12 reverses and becomes the opposite direction from the maximum deformation state. In this state, the deformed state of the container-holding frame 10 can be maintained. Although the reason for this is unclear, it is presumed that as the bending direction of the legs 12 changes to the opposite direction, a stress acts on the legs 12 that counteracts the force that causes the legs 12 in the maximum deformation state to return to their pre-deformed sheet shape, thereby suppressing the return of the container-holding frame 10 to its original shape, allowing the deformed state to be maintained.

[0048] 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.

[0049] 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 a jig or the like. As an example, as partially shown in FIG. 6, there is an embodiment using a jig J in which the inside of a square cylindrical main body J1 is partitioned by a cross frame J2. In this case, as shown in Figure 6(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 the main body J1 and the partition frame 11b of the outer frame portion 11 at the upper end surface of the cross frame J2.

[0050] 6(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. 6(b), the pusher P is lowered from above toward the container holding portion on which the container 20 is placed, and the container 20 is pushed in together with the bottom 13 and the legs 12, thereby transforming the container 20 into the container holding frame 10. Note that the container 20 may be pushed in by hand without using the pusher P. In this case, 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 6(c), the pusher P is raised and retracted.

[0051] 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.

[0052] 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.

[0053] 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). Furthermore, the width of the legs 12 does not have to be constant, and they may taper toward the bottom 13 or toward the outer frame 11. The outer frame 11 may have an annular shape other than a rectangular ring, such as a circular ring or a square ring. The number of legs 12 may also be five, seven or more, instead of six as in the embodiment. It may also be five or less. 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.

[0054] The crease 12a at the boundary between the outer frame portion 11 and the leg portion 12, the crease 12b at the boundary between the leg portion 12 and the bottom portion 13, the perforation 11d in the outer frame portion 11, and the notch 11e may all be omitted. Figures 7 and 8 show a holding frame sheet in which the creases have been omitted. Also, in the embodiment, the crease 12a and the crease 12b are shown as examples of easy-to-fold lines, but the present invention is not limited to this, 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 perforation 11d, other easily breakable lines such as half cuts may be used. [Explanation of symbols]
