Description

The present invention relates to a reinforcing plate for a storage container used as a storage container for storing a long wound body, a storage container, and a storage container containing a wound body.

The storage container described above includes a container body having an open top surface and a lid that opens and closes the opening. The container body stores a long wound body such as a wrap film. The container body is provided with a peripheral wall erected on the bottom plate, and the opening of the container body is partitioned by the upper side of the peripheral wall. The peripheral wall of the container body includes a front plate and a rear plate that face each other. The lid body includes an upper lid plate rotatably connected to the upper side of the rear plate and a cover plate connected to the front side of the upper lid plate. The cover plate is bent from the front side of the upper lid plate toward the bottom plate, and covers the upper part of the front plate on the front side of the front plate (see, for example, Patent Documents 1 and 2).

The storage container is provided with a cutting blade for cutting a long object on the lower side of the cover plate. When cutting a long object pulled out from the storage container, the user of the storage container first opens the lid and pulls out the long object from the opening of the container body. Next, the lid body is closed, and the central portion of the cover plate is pressed against the front plate by the thumb of the hand holding the container body. As a result, the long object is sandwiched between the cover plate and the front plate, and the long object is positioned. Finally, the user of the storage container inserts a part of the cutting blade into the drawn long object and turns the container body in the circumferential direction of the winding body to cut the long object.

JP-A-2015-137103 Japanese Unexamined Patent Publication No. 2000-85761

On the other hand, the operation of pressing the lid plate against the front plate is performed every time a long object is cut, causing plastic deformation that dents the lid body and the front plate. The plastic deformation that occurs in the lid and the front plate causes the position of the long object sandwiched between the lid plate and the front plate to shift, which causes variations in the cutting shape and cutting force of the long object.

The storage container described in Patent Document 1 has a concave embossed embossed so that the outer surface of the upper lid plate is recessed in the central portion in the left-right direction of the upper lid plate, and the outer surface of the upper lid plate is raised. It is equipped with an embossed convex emboss. Although the concave embossing and the convex embossing suppress the bending of the upper lid plate by their cooperation, it cannot be said that the plastic deformation of the lid body and the front plate is suppressed, and there is still room for improvement.

In this respect, it can be said that adhering the reinforcing plate to the outer surface of the lid as in the storage container described in Patent Document 2 directly and effectively suppresses the plastic deformation that may occur in the lid and the front plate. .. However, the reinforcing plate adhered to the outer surface of the lid forms a step corresponding to the thickness of the reinforcing plate on the outer surface of the lid, which reduces the ease of handling of the storage container.

For example, in a situation where storage containers are traded, a plurality of storage containers are usually tightly stored in one packing box with the axial directions of the wound bodies aligned, and are transported or displayed at a store. .. At this time, if the storage container is pulled out of the packing box or inserted into the packing box, the reinforcing plate adhered to the outer surface of the lid interferes with the corners and reinforcing plates of other storage containers. , Prevents the insertion and removal of the storage container, and causes the reinforcing plate to come off.

An object of the present invention is to provide a reinforcing plate for a storage container, a storage container, and a storage box containing a wound body, which can suppress plastic deformation of the storage container while suppressing a decrease in ease of handling of the storage container. And.

The reinforcing plate for a storage container for solving the above problems is a reinforcing plate for a storage container used for a storage container for storing a long wound body, and the storage container is a front plate and a rear plate. A lid body provided with a left plate, a right plate, and a bottom plate and having an open upper surface facing the bottom plate, and a lid rotatably connected to the upper side of the rear plate to open and close the opening of the container body. The storage container reinforcing plate is provided on the outer surface of the lid, and the thickness of the storage container reinforcing plate at the outer peripheral portion is located inside the outer peripheral portion of the storage container reinforcing plate. It is thinner than the thickness on the flat part.

According to the above configuration, the step between the outer surface of the reinforcing plate for the storage container and the outer surface of the lid is reduced to the outer peripheral portion of the reinforcing plate for the storage container by the thickness of the outer peripheral portion of the reinforcing plate for the storage container. Is relaxed. Therefore, it is possible to suppress the plastic deformation of the storage container while suppressing the decrease in the ease of handling of the storage container.

In the reinforcing plate for a storage container, the surface shape of the outer peripheral portion may have an arc shape in a cross section along the thickness direction. According to this configuration, since the surface shape of the outer peripheral portion has an arc shape in the cross section, the interference in the storage container is suppressed more effectively than the configuration in which the surface shape of the outer peripheral portion has a stepped shape or the like. can do.

In the storage container reinforcing plate, the thickness of the edge of the storage container reinforcing plate may be 70% or less of the thickness of the flat portion inside the outer peripheral portion of the storage container reinforcing plate. According to this configuration, since the thickness of the edge of the reinforcing plate for the storage container is 70% or less of the inner thickness, interference in the storage container can be suppressed more effectively.

In the storage container, the reinforcing plate for the storage container may be a micro flute. According to this configuration, it is possible to reduce the thickness of the reinforcing plate for the storage container at the outer peripheral portion by punching the reinforcing plate for the storage container. Therefore, the thickness of the reinforcing plate for the storage container at the outer peripheral portion is realized. It also becomes easy to make it thinner.

In the storage container reinforcing plate, the edge of the storage container reinforcing plate has an arc shape protruding toward the left plate on the left side of the center in the left-right direction which is the axial direction of the winding body, and the winding It may have an arc shape protruding toward the right plate on the right side of the center in the left-right direction, which is the axial direction of the rotating body.

As described above, when the storage container is pulled out from the packing box or the storage container is inserted into the packing box, the outer surfaces of the storage containers tend to rub against each other along the axial direction. In this respect, the storage container reinforcing plate having the above-described configuration is provided with an arc shape protruding toward the left plate on the left side and an arc shape protruding toward the right plate on the right side. Therefore, even if the reinforcing plate for the storage container in the storage container that is inserted and removed along the axial direction comes into contact with the other storage container, the direction in which the other storage container can move relatively is the reinforcement for the storage container. Following the edge of the plate, it is deflected to the front side of the reinforcing plate for the storage container or the rear side of the reinforcing plate for the storage container. This reduces interference between the storage container reinforcing plate and other storage containers. As a result, it is possible to provide a more suitable configuration according to the situation in which the storage container is handled.

The storage container for solving the above-mentioned problems is a storage container for storing a long wound body, and includes a front plate, a rear plate, a left plate, a right plate, and a bottom plate, and the bottom plate and the bottom plate. A container body having an open upper surface and a lid body are provided, and the lid body is rotatably connected to the upper side of the rear plate and is connected to the front side of the upper lid plate. The upper lid plate includes a container lid plate that covers the front plate from the front side with the opening closed, and is bent at the front side of the upper lid plate to cover the outer surface of the upper lid plate and the outer surface of the cover plate. The reinforcing plate for the storage container may be provided on the surface.

According to this configuration, since the upper lid plate and the cover plate are provided with a common reinforcing plate, the plastic deformation of the lid body is further suppressed, and the storage container is easy to handle for each of the upper lid plate and the cover plate. Can be suppressed from decreasing.

The storage container containing the winding body for solving the above problems includes a winding body around which a long object is wound and the storage container. According to this storage container containing a wound body, it is possible to suppress the plastic deformation of the storage container while suppressing the decrease in the ease of handling of the storage container.

According to the reinforcing plate for the storage container, the storage container, and the storage container containing the wound body in the present invention, it is possible to suppress the plastic deformation of the lid while suppressing the decrease in the handleability of the storage container. ..

The lower half of the lid front plate 32 partitioned by the perforation line 32M is a cut piece 32K, which is separated from the container body 20 at the start of use of the wrap film 50. When the cut piece 32K is separated from the lid 30, the entire cutting edge of the cutting blade 35 (see FIG. 2) is exposed from the lower end side of the lid plate 32P. Then, the lid 30 rotates on the upper side of the rear plate 22, so that the opening 20T of the container body 20 is opened.

The lid plate 32P has a plate shape extending from the front side of the upper lid plate 31 toward the bottom plate 25 with the lid body 30 closing the opening 20T, and covers the upper part of the front plate 21 from the front side of the front plate 21. .. The width of the cover plate 32P in the height direction is the smallest slightly closer to the center from the end in the left-right direction and the largest in the center in the left-right direction. In manufacturing the storage container 10, the cover plate 32P is bent with respect to the upper lid plate 31 along a ruled line L (see FIG. 3).

A cutting blade 35 is joined to the rear surface (inner surface) of the cover plate 32P. The cutting blade 35 has a saw blade shape having cutting edges arranged in the left-right direction. The cutting blade 35 is joined to the lid plate 32P so that a plurality of cutting edges project downward from the lid plate 32P in a state where the lid 30 closes the opening 20T. The method of bonding the cutting blade 35 to the lid plate 32P is performed by, for example, ultrasonic bonding with a sealant material or an adhesive layer interposed between the lid plate 32P and the cutting blade 35.

The material constituting the cutting blade 35 is not particularly limited, and is, for example, resin or metal. The cutting blade 35 contains, for example, a resin and an additive, and the rigidity of the cutting blade 35 and the adhesiveness of the cutting blade 35 to the lid plate 32P can be adjusted depending on the type of the additive and the amount of the additive added. Further, the sealant layer may be laminated on the resin layer of the blade material constituting the cutting blade 35.

The resin constituting the cutting blade 35 is, for example, a polyester resin such as polylactic acid, polyethylene, polypropylene, polystyrene, acetal resin, polyphenylene sulfide, PEEK (polyetheretherketone) resin, or PES (polyetheralphon) resin. The additive constituting the cutting blade 35 is, for example, a resin such as an olefin resin or an inorganic material such as barium sulfate, calcium carbonate, titanium oxide, silica or talc. As the resin constituting the sealant layer, for example, modified polyolefin in which a functional group is introduced into polyolefin to impart adhesiveness is used.

The lid right plate 33 includes two flaps 33F, 323 (see FIG. 2).
The lid left plate 34 includes two flaps 34F, 324 (see FIG. 2).
In the lid right plate 33 and the lid left plate 34, the flaps 33F and 34F form the outer surface of the lid body 30, and the flaps 323 and 324 form the inner surface of the lid body 30. The lid right plate 33 and the lid left plate 34 cover the upper part of the right plate 23 from the side of the right plate 23 with the lid body 30 closing the opening 20T, and the left plate from the side of the left plate 24. Cover the top of 24.

The flaps 323 and 324 are located with a gap between them and the upper lid plate 31, and stepped portions 33S and 34S are formed on the inner surfaces of the flaps 33F and 34F. When the lid body 30 closes the opening 20T, the lid locking pieces 3T and 4T described above fit into the stepped portions 33S and 34S, generate a clicking sound, and engage with the stepped portions 33S and 34S. The lid locking pieces 3T and 4T suppress the upper lid plate 31 from being lifted in the closed state through engagement with the stepped portions 33S and 34S.

When forming the lid 30, first, the flaps 323 and 324 are bent at the ruled line LT (see FIG. 3) with respect to the lid plate 32P. Next, the flaps 33F and 34F are bent at the ruled line LT (see FIG. 3) with respect to the upper lid plate 31. Finally, the space between the flap 33F and the flap 323 and the space between the flap 34F and the flap 324 are bonded with a glue such as hot melt.

[Reinforcing plate 41]
Returning to FIG. 1, the storage container 10 is provided with a reinforcing plate 41 on the outer surface of the lid 30.
The reinforcing plate 41 has an elliptical plate shape having a long axis extending along the axial direction A. That is, the edge of the reinforcing plate 41 has an arc shape protruding toward the right plate 23 on the right side of the center of the reinforcing plate 41 in the axial direction A. Further, the edge of the reinforcing plate 41 has an arc shape that protrudes toward the left plate 24 on the left side of the center of the reinforcing plate 41 in the axial direction A. The range in which the reinforcing plate 41 is located includes the center of the axial direction A on the outer surface of the upper lid plate 31 and the center of the axial direction A on the outer surface of the cover plate 32P.

The reinforcing plate 41 is composed of, for example, a single sheet of paper such as coated cardboard or a sheet of interleaving paper between coated cardboard and flute. The paper material constituting the reinforcing plate 41 is, for example, a micro flute such as an E flute, an F flute, or a G flute. From the viewpoint that the thickness of the reinforcing plate 41 can be reduced, the paper material constituting the reinforcing plate 41 is preferably a G flute. The rigidity of the paper material constituting the reinforcing plate 41 is preferably higher than that of the paper material constituting the lid 30 from the viewpoint of increasing the rigidity of the upper lid plate 31 and the lid plate 32P, but the lid 30 is configured. It may be lower than the paper material to be used.

The bottom surface (back surface) of the reinforcing plate 41 is adhered to the outer surface of the lid 30 by a glue such as hot melt. The reinforcing plate 41 is bent in an L shape at a portion facing the upper side of the front plate 21. The reinforcing plate 41 straddles the outer surface of the cover plate 32P and the outer surface of the upper lid plate 31, and is adhered to the cover plate 32P and the upper lid plate 31. The bottom surface of the reinforcing plate 41 is a portion not provided with a liquid-repellent coating or the like in order to increase the adhesive strength with the outer surface of the lid 30, like the adhesive surfaces of the flaps 33F, 323, 34F, and 324. .. The reinforcing plate 41 is preferably formed so as to be bent in an L shape at a portion facing the upper side of the front plate 21, but is preferably the outer surface of the cover plate 32P or the outer surface of the upper lid plate 31. The form may be provided on only one of the surfaces.

Further, when the reinforcing plate 41 is adhered across the upper lid plate 31 and the cover plate 32P, a fold ruled line may be provided on the reinforcing plate 41. By making the corrugated shape of the microflute core parallel to the fold ruled line, it is possible to easily bend the reinforcing plate 41 with a smaller bending force.

Further, the reinforcing plate 41 may be adhered so as to include the center of the lid 30 in the axial direction A. According to this, the portion particularly easily plastically deformed by the cutting operation of the wrap film 50 can be reinforced by the reinforcing plate 41.

In the manufacture of the storage container 10, the reinforcing plate 41 is adhered to the lid 30 in a bent state, for example. According to this manufacturing method, the strain at the bent portion of the lid 30 is reduced by the storage container 10 as compared with the method in which the reinforcing plate 41 is adhered to the intermediate body described above and the reinforcing plate 41 is bent together with the formation of the lid 30. Can be reduced with. An example in which the long axis of the reinforcing plate 41 faces the upper side of the front plate 21 will be described, but it may be on the outer surface of the upper lid plate 31 or on the outer surface of the cover plate 32P. There may be.

The outer surface of the reinforcing plate 41 is, for example, printed continuously with the printing applied to the outer surface of the lid 30. As a result, the printing applied to the outer surface of the reinforcing plate 41 and the printing applied to the outer surface of the lid 30 are visually recognized as one piece of printing, and the lid 30 and the reinforcing plate 41 The design of the lid is improved.

As shown in FIG. 4, the reinforcing plate 41 includes an outer peripheral portion 41E.
The outer peripheral portion 41E of the reinforcing plate 41 is a portion of the reinforcing plate 41 whose thickness is gradually changed, and includes the entire edge of the reinforcing plate 41. The thickness of the outer peripheral portion 41E is the thinnest at the edge of the reinforcing plate 41. The thickness of the outer peripheral portion 41E changes so as to be thinner toward the edge of the reinforcing plate 41, for example. The width of the outer peripheral portion 41E of the reinforcing plate 41 is, for example, 0.2 mm or more and 5 mm or less, preferably 0.4 mm or more and 3 mm or less, and more preferably 0.6 mm or more and 2 mm or less. When the outer peripheral portion 41E has a width of 0.2 mm or more, interference in the storage container 10 can be effectively suppressed, and when it is 5 mm or less, the workability of the outer peripheral portion 41E can be facilitated.

The surface shape of the outer peripheral portion 41E of the reinforcing plate 41 has an arc shape in a cross section along the thickness direction of the reinforcing plate 41. The arc shape in the cross section of the surface shape of the outer peripheral portion 41E is a shape that becomes convex toward the outside in the axial direction A. That is, the decrease in thickness at the outer peripheral portion 41E changes so that, for example, the portion closer to the edge of the reinforcing plate 41 becomes larger.

In manufacturing the reinforcing plate 41, the reinforcing plate 41 is punched out from the paper material by using, for example, a die-cutting machine for manufacturing the reinforcing plate 41. At this time, the blade edge shape of the blade such as the Thomson blade mounted on the die cutting machine has a shape that follows the surface shape of the outer peripheral portion 41E. Then, the outer peripheral portion 41E of the reinforcing plate 41 punched from the paper material is punched into a shape that follows the shape of the cutting edge of the die cutting machine, and has a thickness T4E thinner than the flat portion at the edge.

The entire area inside the outer peripheral portion 41E of the reinforcing plate 41 is the inner peripheral portion of the reinforcing plate 41.
The inner peripheral portion of the reinforcing plate 41 includes a flat portion in the reinforcing plate 41. All of the inner peripheral portions of the reinforcing plate 41 may be flat portions, or may be provided with convex embossing and flat portions protruding from the flat portions. The flat portion is a portion of the reinforcing plate 41 having the thickness of the paper material itself constituting the reinforcing plate 41.

The thickness T4E at the edge of the outer peripheral portion 41E is thinner than the thickness T4B at the flat portion of the inner peripheral portion. The thickness T4E at the edge of the outer peripheral portion 41E is, for example, 70% or less, preferably 60% or less, and more preferably 50% or less of the thickness T4B at the flat portion.

The thickness T4E at the edge of the outer peripheral portion 41E is, for example, 0.2 mm or more and 1.0 mm or less. When the thickness T4E at the edge of the outer peripheral portion 41E is 1.0 mm or less, the formation of a step between the outer surface of the reinforcing plate 41 and the outer surface of the lid 30 can be easily suppressed by the edge of the outer peripheral portion 41E.

The thickness T4B at the flat portion is, for example, 0.35 mm or more and 1.5 mm or less. When the thickness T4B at the flat portion is 0.35 mm or more, the plastic deformation of the lid 30 can be easily suppressed by the reinforcing plate 41. When the thickness T4B of the flat portion is 1.5 mm or less, it is easy to form the outer peripheral portion 41E for suppressing the step between the outer surface of the reinforcing plate 41 and the outer surface of the lid 30.

The bottom surface of the reinforcing plate 41 and the portion of the outer surface of the lid 30 to which the reinforcing plate 41 is attached are different from the periphery of the portion, in order to increase the adhesive strength between the reinforcing plate 41 and the lid 30. , Water-repellent coat, UV varnish coat, etc. are not applied.

The thickness T3 of the upper lid plate 31 is, for example, 0.35 mm or more and 0.7 mm or less. When the thickness T3 of the upper lid plate 31 is 0.35 mm or more, it is easy to suppress the plastic deformation of the upper lid plate 31. When the thickness T3 of the upper lid plate 31 is 0.7 mm or less, it is easy to reduce the weight of the storage container 10.
The relationship between the thickness T4E, the thickness T4B, and the thickness T3 of the upper lid plate 31 satisfies the following conditions 1 and 2 as an example.
(Condition 1) Thickness T4E <Thickness T4B
(Condition 2) Thickness T4E <Thickness T3

[Action]
When using the wrap film 50, the user of the storage container containing the wound body holds, for example, the storage container 10 in which the lid 30 is opened with his left hand and the tip of the wrap film 50 with his right hand. Next, the wrap film 50 is pulled out from between the cover plate 32P and the front plate 21. Subsequently, the lid 30 is rotated with the thumb of the left hand so that the lid 30 is closed, and the storage container 10 is rotated about the central axis along the axial direction A while pressing the central portion of the lid plate 32P with the thumb of the left hand. .. As a result, the tooth tips of the cutting blade 35 are inserted into the wrap film 50, and the wrap film 50 is cut.

At this time, the operation of pressing the central portion of the cover plate 32P against the front plate 21 is performed every time the wrap film 50 is cut, and the lid 30 and the front plate 21 are plastically deformed. The plastic deformation that occurs in the lid 30 and the front plate 21 causes the position of the wrap film 50 sandwiched between the lid plate 32P and the front plate 21 to shift, which causes variations in the cutting shape and cutting force of the wrap film 50. Will be.

In this respect, the reinforcing plate 41 adhered to the lid 30 increases the rigidity of the portion of the lid 30 where the pressing force can act, such as the central portion in the axial direction A of the lid 30. The plastic deformation that may occur in the lid 30 and the front plate 21 is suppressed.

Here, in the configuration in which the reinforcing plate 41 is provided while the reinforcing plate 41 is provided as a mere flat plate, the reinforcing plate 41 adhered to the cover plate 32P and the upper lid plate 31 has a step corresponding to the thickness T4B of the reinforcing plate 41. Is formed on the outer surface of the lid 30, which reduces the ease of handling of the storage container 10.

For example, the plurality of storage containers 10 are densely stored in one packing box with their respective axial directions A aligned, and are transported or displayed at a store. At this time, when the storage container 10 is taken out of the packing box or inserted into the packing box, the reinforcing plate 41 adhered to the outer surface of the lid 30 becomes a corner portion of another storage container 10 or the reinforcing plate 41. It interferes with such a thing, hinders the insertion and removal of the storage container 10, and causes the reinforcing plate 41 to peel off.

In this respect, the step between the outer surface of the reinforcing plate 41 and the outer surface of the lid 30 is relaxed by the outer peripheral portion 41E of the reinforcing plate 41 by the amount that the outer peripheral portion 41E of the reinforcing plate 41 is thinner. That is, the interference at the portion of the reinforcing plate 41 that begins to interfere with other structures is alleviated. As a result, since the interference in the storage container 10 when it is inserted and removed from the packing box is reduced, it is possible to suppress the plastic deformation of the storage container 10 while suppressing the decrease in the ease of handling of the storage container 10.

As described above, according to the above embodiment, the following effects can be obtained.
(1) Since the interference in the storage container 10 when the storage container 10 is inserted and removed from the packing box is reduced by the outer peripheral portion 41E of the reinforcing plate 41, the ease of handling of the storage container 10 due to the addition of the reinforcing plate 41 It is possible to suppress the plastic deformation of the storage container 10 due to the cutting operation of the wrap film 50 while suppressing the decrease in the amount.

In addition, during the cutting operation of the wrap film 50, the reinforcing plate 41 suppresses the elastic deformation of the lid 30 itself, so that the cutting operation of the wrap film 50 can be stabilized and the shape of the cut end of the wrap film 50 can be stabilized. Is also possible.

(2) When the surface shape of the outer peripheral portion 41E has an arc shape in a cross section along the thickness direction, the storage container is more effective than the configuration in which the surface shape of the outer peripheral portion 41E has a stepped shape or the like. Interference at 10 can be suppressed.

(3) When the edge thickness T4E of the reinforcing plate 41 is 70% or less of the thickness of the flat portion inside the outer peripheral portion 41E of the reinforcing plate 41, the edge thickness T4E is the thickness T4B of the flat portion. It is possible to more effectively suppress the interference in the storage container 10 as compared with the configuration equivalent to the above.

(4) When the reinforcing plate 41 is a micro flute, it is possible to reduce the thickness of the reinforcing plate 41 at the outer peripheral portion 41E by punching the reinforcing plate 41 or the like. Therefore, it is easy to reduce the thickness of the reinforcing plate 41 at the outer peripheral portion 41E.

(5) When the upper lid plate 31 and the cover plate 32P are provided with a common reinforcing plate 41, plastic deformation in the lid 30 is further suppressed, and the upper lid plate 31 and the cover plate 32P are each provided. It is possible to prevent the storage container 10 from being easily handled. Therefore, it is possible to provide a more suitable configuration according to the situation in which the storage container containing the wound body is handled.

(6) Since the edge of the reinforcing plate 41 has an elliptical shape, even if the reinforcing plate 41 of the storage container 10 inserted and removed along the axial direction A comes into contact with another storage container 10, the storage container 10 moves. The direction of movement follows the edge of the reinforcing plate 41 and is deflected to the front or the rear of the reinforcing plate 41. As a result, the interference between the reinforcing plate 41 and the other storage container 10 is reduced. As a result, it is possible to provide a more suitable configuration according to the situation in which the storage container containing the wound body is handled.

The above embodiment can also be modified and implemented as follows.
[Reinforcing plate 41]
As shown in FIG. 5, the arc shape of the surface shape in the cross section of the outer peripheral portion 41E can be changed to a shape that is convex toward the inside in the axial direction A. That is, the decrease in thickness at the outer peripheral portion 41E may change so that, for example, the portion closer to the edge of the reinforcing plate 41 becomes smaller. Even with this surface shape, for example, the cutting edge shape of the blade mounted on the die cutting machine can be manufactured by having a shape that follows the surface shape of the outer peripheral portion 41E, and the thickness T4E thinner than the flat portion can be obtained. Will have on the edge.

-The reinforcing plate 41 may have a circular shape or a polygonal plate shape having a triangle shape or more, or may have an amorphous plate shape other than an elliptical plate shape or a polygonal plate shape. Even when the reinforcing plate 41 has a polygonal plate shape or an amorphous plate shape, it is possible to obtain the effects according to the above (1) to (5). Further, when the reinforcing plate 41 has an amorphous plate shape, it is possible to set the shape according to the printing applied to the outer surface of the storage container 10 and the arrangement of other functional parts, so that the storage container can be set. It is also possible to enhance the design and functionality of the outer surface of 10.

The reinforcing plate 41 is not limited to a position including the center of the lid 30 in the axial direction A, and may be arranged at a position other than the center of the lid 30 in the axial direction A. Further, the position of the reinforcing plate 41 is relatively aligned with the portion where the pressing force can be applied, such as a position where the reinforcing plate 41 can face the gap of the front plate flap 21F or a position where the reinforcing plate 41 can face the temporary fixing portion 21S. It may be arranged as follows. Further, since the four corners of the upper lid plate 31 are highly rigid portions connected to the two plates other than the upper lid plate 31, the reinforcing plate 41 is upper from the viewpoint of increasing the rigidity of the lid 30. It is preferably located at other than the four corners of the lid plate 31.

-Furthermore, the number of reinforcing plates 41 is not limited to one, and may be two or more. For example, the reinforcing plates 41 may be arranged along the axial direction A, or may be arranged separately on the cover plate 32P and the upper lid plate 31.

If the number of reinforcing plates 41 is two or more, even if the pressing force is repeatedly applied to the center of the lid 30 in the axial direction A, the pressing force is applied to other than the center of the lid 30 in the axial direction A. Since it is possible to suppress the plastic deformation of the lid 30 even when it is repeatedly applied, it is also possible to cope with the diversification of the portion where the pressing force is repeatedly applied.

-The part of the reinforcing plate 41 that can be bent can be changed to a ruled line that is recessed toward the inside of the storage container 10. At this time, it is preferable that the ruled line L, which is the boundary between the upper lid plate 31 and the cover plate 32P, is also a ruled line recessed toward the inside of the storage container 10. In this configuration, the ruled line of the reinforcing plate 41 and the ruled line of the lid 30 are recessed in the same direction, so that the adhesive strength between the ruled line of the reinforcing plate 41 and the ruled line of the lid 30 is increased. Is also possible.
The reinforcing plate 41 may be made of a material other than paper, such as resin or metal.

[Other]
-The height at the front end of the lid 30 and the height at the rear end of the lid 30 are preferably equal to each other from the viewpoint of enhancing the stability when the storage containers 10 are stacked in multiple stages. That is, since the thickness of the reinforcing plate 41 is an element that can determine the height at the front end of the lid 30, the thickness T4B is the height at the front end of the lid 30 and the height at the rear end of the lid 30. It is preferable that the heights are set to be equal to each other.

-The shape of the cutting blade is not limited to a gentle V-shape extending in the left-right direction, but can be changed to, for example, a straight line extending in the left-right direction. Further, the cutting blade is not limited to the full width extending in the left-right direction, and may have a shape having a cutting blade at a part such as an end portion or a central portion in the left-right direction.
-Long items can be changed to aluminum foil or cooking sheets.
