Description

Embodiments of the present invention relate to a pen case.

Conventionally, it is formed in the shape of a bag that can store stationery inside, and consists of a pen case that opens and closes with a fastener etc., and a lid and a container body, and a pen that engages the lid and the container body with a magnet member etc. Cases etc. are known. However, when it is opened and closed by a fastener, a magnet member, or the like, it may not be usable due to a defect in the fastener, the magnet member, or the like.

Therefore, a pen case has been devised that is equipped with a storage base cloth band to be stored in the case body and upper and lower edging tapes, and the storage base cloth band is stored in the case body by winding the edging tape all at once by the upper and lower winding mechanisms. ing. The take-up mechanism has, for example, a three-layer structure consisting of a cam, a rotor, and a spring.

However, in both the case of a pen case that opens and closes with a conventional fastener or magnet, and the case of a pen case that opens and closes with a take-up mechanism, the user cannot quickly open and close the pen case without operating it with both hands, for example, in a hurry. It is inconvenient when you want to put away the pen case and carry it. Further, in the case of the winding mechanism, there is a possibility that the structure becomes complicated, the manufacturing cost increases, and the failure easily occurs.

Hereinafter, the pen case according to the embodiment will be described with reference to the drawings.
First, the schematic configuration of the pen case 10 will be described with reference to FIG. As shown in FIG. 1, the pen case 10 is configured to have a plurality of accommodating portions 12 in a rectangular pen case main body 11. In the following description, the side of the pen case main body 11 having the accommodating portion 12 is referred to as the inner surface side of the pen case 10, and the side opposite to the accommodating portion 12 is referred to as the outer surface side of the pen case 10. Further, the vertical direction on the paper surface of FIG. 1 is the vertical direction of the pen case 10, and the left-right direction on the paper surface of FIG. 1 is the left-right direction, that is, the width direction of the pen case 10. Further, the direction penetrating the paper surface of FIG. 1, that is, the direction perpendicular to the vertical direction and the horizontal direction is defined as the thickness direction of the pen case 10.

In the case of the present embodiment, the vertical direction with respect to the pen case 10 coincides with the vertical direction of the pen case 10 when the pen case 10 is rolled into a tubular shape and placed upright on a desk or the like as shown in FIG. Further, the pen case 10 is configured as a whole in a rectangular shape long in the left-right direction on the paper surface of FIG. 1 in the unfolded state as shown in FIG. Therefore, in the following description, the vertical direction of the pen case 10 may be referred to as a lateral direction or a first direction, and the horizontal direction of the pen case 10 may be referred to as a longitudinal direction or a second direction.

As shown in FIGS. 1 and 2, the pen case 10 is mainly composed of the pen case main body 11. The pen case main body 11 is made of a flexible sheet-like member. The members constituting the pen case main body 11 include not only cloth materials, thinly processed fibers, and woven fabrics, but also knitted fabrics, laces, felts, non-woven fabrics, and leather. The fibers may be natural fibers, regenerated fibers, or synthetic fibers. The pen case main body 11 can be made of, for example, a chemical fiber such as nylon, a natural fiber such as cotton, or natural or synthetic leather. In this case, the pen case main body 11 is configured by stacking at least two sheet-like members of the inner sheet 111 and the outer sheet 112. The inner sheet 111 is a sheet-like member constituting the inner surface side of the pen case main body 11. The outer sheet 112 is a sheet-like member constituting the outer surface side of the pen case main body 11.

As shown in FIGS. 1 and 5 to 7, the pen case main body 11 has an accommodating portion 12, a flap portion 13, a lid portion 14, and a regulating portion 15. The accommodating portion 12 is provided at the lower end of the surface of the inner sheet 111 of the pen case main body 11. The accommodating portion 12 is formed in the shape of a pocket with an open upper part, and for example, a stationery 40 such as a pen can be stored in and out. The pen case main body 11 has a plurality of accommodating portions 12 provided along the width direction of the pen case main body 11 in this case. The object to be accommodated in the pen case 10 is not limited to stationery, but the case where the stationery 40 is accommodated will be described below as an example.

In the present embodiment, the accommodating portion 12 has a plurality of accommodating portions 121, in this case, five first accommodating portions 121 and one second accommodating portion 122. The first accommodating portion 121 is formed elongated in the vertical direction, and can accommodate one or a plurality of long stationery items such as pens inside each first accommodating portion 121. The vertical length dimension of the first accommodating portion 121 is, for example, a dimension capable of accommodating more than half of the stationery 40 in the length direction. The length dimension of each of the first accommodating portions 121 in the left-right direction may be the same, or some or all of them may be different from each other. It is a size that can be done.

The second accommodating portion 122 is formed in a horizontally long rectangular shape, and is provided at one end in the width direction of the pen case main body 11. In this case, the vertical length dimension of the second accommodating portion 122 is set shorter than the vertical length dimension of the first accommodating portion 121. Further, the length dimension of the second accommodating portion 122 in the left-right direction is set to be longer than the length dimension of the first accommodating portion 121 in the left-right direction. Therefore, the second accommodating portion 122 is configured to be easy to take out when accommodating a small stationery 40 such as an eraser or a clip. Further, as shown in FIG. 5, a plurality of long stationery 40s such as pens can be simultaneously accommodated in the second accommodating portion 122.

The flap portion 13 is formed in a rectangular shape, and as shown in FIGS. 5 to 7, the flap portion 13 is provided so as to hang downward from the upper end portion of the surface of the inner sheet 111 of the pen case main body 11. The flap portion 13 is movably configured with the upper end portion of the pen case main body 11 as a base end. That is, the flap portion 13 can be folded upward with the upper end of the pen case main body 11 as the base end. By operating the flap portion 13, the user can arrange the flap portion 13 on the back side of the stationery 40, that is, between the stationery 40 and the pen case main body 11, and the flap portion 13 can be arranged on the front side of the stationery 40, that is, on the front side of the stationery 40. The stationery 40 can also be placed on the opposite side of the pen case body 11. When the flap portion 13 is arranged on the front side of the stationery 40, the flap portion 13 covers the upper part of the stationery 40 housed in the storage part 12 and functions as a cover for preventing the stationery 40 from falling off from the storage part 12. Have.

The lid portion 14 is rotatably provided above the second accommodating portion 122 on the surface of the inner sheet 111, and opens and closes the opening above the second accommodating portion 122. The lid portion 14 has a function of suppressing a small stationery 40 such as an eraser housed in the second storage portion 122 from falling off from the second storage portion 122. Since the length dimension of the lid portion 14 in the left-right direction is set shorter than the length dimension of the second accommodating portion 122 in the left-right direction, the lid portion 14 is used by being inserted inside the second accommodating portion 122. You can also do it. Therefore, the lid portion 14 does not prevent the second accommodating portion 122 from accommodating the stationery 40 or the like, which is longer than the vertical length dimension of the second accommodating portion 122. The accommodating portion 12, the flap portion 13, and the lid portion 14 are each composed of a flexible sheet-like member. The members constituting the accommodating portion 12, the flap portion 13, and the lid portion 14 may be the same as the members constituting the pen case main body 11, or may be different members.

The restricting portion 15 is formed in a flexible strip shape, and is provided above the second accommodating portion 122 and the lid portion 14 on the surface of the inner sheet 111. Both ends of the regulating portion 15 in the left-right direction are fixed to the pen case main body 11. The portion other than the fixed left and right ends of the regulating portion 15, that is, the central portion in the left-right direction is not fixed to the pen case main body 11. Therefore, for example, as shown in FIG. 11, the restricting unit 15 can restrict the movement of the stationery 40 accommodated in the second accommodating unit 122 by being sandwiched between the clip portions of the stationery 40 such as a pen. That is, the regulating unit 15 has a function of suppressing the long stationery 40 from falling off from the second accommodating unit 122. Further, the stationery unit 40 such as a clip that is not accommodated in the second accommodating portion 122 may be hooked on the regulation unit 15 for use.

The pen case 10 includes a deforming member 20 formed in an elongated plate shape, as shown by a broken line in FIGS. 1, 2 and 4. In this case, the deforming member 20 has the left-right direction as the longitudinal direction and the vertical direction as the lateral direction. The deformable member 20 is made of a member that can be elastically deformed. In the present embodiment, the deforming member 20 is made of a thin metal plate such as stainless steel. In another embodiment, the deformable member 20 may be made of a synthetic resin or the like having strength and malleability. In this case, the deforming member 20 is provided sandwiched between the sheet-shaped member constituting the inner surface side of the pen case main body 11 and the sheet-shaped member constituting the outer surface side.

The configuration of the deformable member 20 will be described with reference to FIGS. 8 to 10 in a state of being removed from the pen case 10. As shown in FIG. 8, the deformable member 20 is wound in a state of being extended in an elongated plate shape, that is, in a first state of being developed in a plate shape as a whole, and as shown in FIG. It is possible to stably take two states, that is, the second state wound in a cylindrical shape. The deformable member 20 has a so-called bistability structure. The deforming member 20 can switch between the first state and the second state by applying an external force. FIG. 9 shows an intermediate state which is a process of changing the deforming member 20 from the first state to the second state. Since this intermediate state is a physically unstable state, the deforming member 20 tends to be in either the first state or the second state.

As shown in FIG. 8, the deformable member 20 is curved in the lateral direction in the first state. In this case, the front side with respect to the paper surface of FIG. 8, that is, the inner surface side of the pen case 10 is a convex surface. That is, assuming that the inner surface side of the pen case 10 of the deforming member 20 is the first surface 21 and the outer surface side of the pen case 10 is the second surface 22, the first surface 21 forms a convex surface in the first state, and the second surface is formed. 22 forms a concave surface. This curvature stabilizes the first state of the deforming member 20.

When an external force having a component in the direction perpendicular to the first surface 21 or the second surface 22 is applied to the deforming member 20 in the first state, the deforming member 20 changes to the second state. That is, when an external force acts in the direction of reducing the curvature of the deformable member 20, the stability of the first state is lost, and the deformable member 20 contracts while rotating in the longitudinal direction and changes to the second state.

In the second state shown in FIG. 10, the first surface 21 and the second surface 22 of the deformable member 20 are not substantially curved in the lateral direction. In the second state, the deforming member 20 has a repulsive force that hinders the movement spreading outward in the radial direction, and functions as a spring. When a sufficient external force that pulls the end portion 23 of the deforming member 20 radially outward is applied to the deforming member 20 in the second state, the deforming member 20 overcomes the repulsive force of the spring and changes to the first state again. Can be done. When the deforming member 20 is extended by an external force for a certain length or more in the longitudinal direction and an external force that warps the deforming member 20 so as to make the first surface side convex is applied to the deforming member 20, the deforming member 20 is curved in the lateral direction. Is formed, and the deforming member 20 can take the first state.

As shown in FIGS. 1 and 2, the pen case main body 11 further includes a holding portion 16 and an operating portion 17. The holding portion 16 is formed in a horizontally long rectangular shape at the central portion of the pen case main body 11 in the vertical direction over the entire width in the horizontal direction of the pen case main body 11. The holding portion 16 has a function of holding the deforming member 20. That is, the deforming member 20 is held in the central portion of the pen case main body 11 in the vertical direction. In this case, the central portion of the pen case main body 11 is a concept including a range moved in the vertical direction by 5% from the center of the vertical length dimension of the pen case main body 11. In the present embodiment, the vertical center position of the pen case main body 11 and the vertical center position of the deformable member 20 coincide with each other. Further, the deforming member 20 is provided over the entire width of the pen case main body 11 in the left-right direction. In this case, "over the entire width" means that the length dimension of the deformable member 20 in the left-right direction, that is, the longitudinal direction is 90% or more of the length dimension in the left-right direction of the pen case main body 11.

When the pen case 10 is expanded, that is, the accommodating portion 12 is exposed to the outside as shown in FIGS. 1 and 2, the deformable member 20 held by the holding portion 16 takes the first state. ing. In this case, the holding portion 16 may be configured such that a band-shaped member is attached to the surface of the outer sheet 112 and the deformable member 20 is held between the band-shaped member and the outer sheet 112. The holding portion 16 and the outer sheet 112 may be sewn or may be adhered with an adhesive or the like. In another embodiment, the holding portion 16 is formed so that the deformable member 20 can be held inside by sewing a part of the inner sheet 111 and the outer sheet 112 in a bag shape or adhering them with an adhesive or the like. You may.

As shown in FIG. 1, the operation unit 17 is provided at a position overlapping both ends of the holding unit 16 in the left-right direction on the inner surface side of the pen case main body 11, that is, on the surface of the inner sheet 111. The operation unit 17 is arranged at a position where at least a part of the end portion 23 of the deforming member 20 overlaps with the thickness direction of the pen case main body 11. The operation unit 17 may be made of a sheet-like member thicker than the pen case main body 11. Further, the operation unit 17 may be composed of a sheet-like member having a friction coefficient larger than that of the pen case main body 11. In the present embodiment, the operation unit 17 is provided at both ends of the holding unit 16 in the left-right direction, but in another embodiment, the operation unit 17 may be provided at one end.

As shown in FIG. 1 and the like, the pen case main body 11 has a folded region 18. The folded region 18 forms the upper half of the pen case body 11. The folded region 18 has the upper end portion of the holding portion 16 or the upper end portion thereof as the lower end, and the upper end portion of the pen case main body 11 as the upper end portion. Specifically, the folded region 18 has the upper end portion of the holding portion 16 as the lower end and the upper end portion of the pen case main body 11 as the upper end portion. That is, the flap portion 13 is fixed to the upper end of the folded region 18. The first accommodating portion 121, the second accommodating portion 122, the lid portion 14, the regulating portion 15, the holding portion 16, and the operating portion 17 are located in a portion other than the folded region 18 of the pen case main body 11.

The folded region 18 can be folded toward the outer surface side of the pen case main body 11 with the side portion in the longitudinal direction of the deforming member 20 as a fulcrum, that is, the base end of the folded member. In this case, the folded region 18 can be folded toward the outer surface side of the pen case main body 11 with the upper longitudinal side portion of the deforming member 20 as a fulcrum. In other words, the folded region 18 can be folded toward the outer surface side of the pen case main body 11 with the vicinity of the upper end of the holding portion 16, that is, the upper end of the deforming member 20 as the folded line L. The holding portion 16, the accommodating portion 12, and the operating portion 17 are located on the inner surface side of the pen case main body 11 in the folded state in which the folded region 18 is folded back. That is, the holding portion 16, each accommodating portion 12, and the operating portion 17 are located below the folding line L. In the folded state, the long stationery 40 accommodated in the accommodating portion 12 may have an upper portion protruding from the folded line L as shown in FIG.

Further, as shown in FIGS. 3 and 4, the pen case 10 includes a plurality of auxiliary members 30. The plurality of auxiliary members 30 are formed, for example, in the shape of an elongated rectangular thin plate, and are provided along each end of the pen case body 11 in the longitudinal direction. The shape of the auxiliary member 30 is not limited to a thin plate, and in another embodiment, the auxiliary member 30 may be, for example, a columnar or a prismatic shape.

The auxiliary member 30 has a rigidity higher than the rigidity of the pen case main body 11. Therefore, the auxiliary member 30 has a function of adding rigidity to both ends of the pen case 10 and suppressing the end of the pen case main body 11 from warping. That is, the auxiliary member 30 has a function of maintaining the shape of the end portion of the pen case main body 11.

In addition, the auxiliary member 30 has foldable flexibility and therefore does not prevent the user from folding back the folded area 18. The auxiliary member 30 can be made of a synthetic resin having rigidity such as polyethylene and flexibility to reversibly bend under an external force. Further, the thickness of the auxiliary member 30 is set to a thickness that suppresses the end of the pen case main body 11 from bending and does not prevent the user from folding back the folded region 18. In this case, the thickness of the auxiliary member 30 can be set in the range of, for example, 0.05 mm to 0.4 mm. In the present embodiment, the thickness of the auxiliary member 30 is set to 0.02 mm. Further, the width dimension of the auxiliary member 30, that is, the length dimension in the longitudinal direction of the pen case main body 11 can be set in the range of, for example, 5 mm to 1.5 mm. In the present embodiment, the width dimension of the auxiliary member 30 is set to 8 mm.

A plurality of auxiliary members 30 may be provided so as to overlap each other. In the present embodiment, the auxiliary members 30 are doubly overlapped with each other. The pen case 10 includes a first auxiliary member 31 as an auxiliary member 30, a second auxiliary member 32 and a third auxiliary member 33 provided on the outer surface side of the pen case main body 11 with respect to the first auxiliary member 31. To prepare for.

The first auxiliary member 31 is provided so as to straddle the folding line L. The first auxiliary member 31 is provided over the entire length of the pen case main body 11 in the lateral direction, that is, in this case, in the vertical direction. In this case, the total length in the vertical direction means that it is 90% or more of the length dimension in the vertical direction.

Both the second auxiliary member 32 and the third auxiliary member 33 have a shorter length than the first auxiliary member 31, and both are provided without straddling the folding line L. The second auxiliary member 32 and the third auxiliary member 33 are located on opposite sides of the folding line L, and are arranged in the pen case main body 11 in the lateral direction, that is, in the vertical direction. That is, the second auxiliary member 32 and the third auxiliary member 33 are provided side by side in a straight line with the folded line L interposed therebetween. The second auxiliary member 32 is provided at a position overlapping the folded region 18 of the pen case main body 11. The third auxiliary member 33 is provided at a position overlapping with a portion other than the folded region 18 of the pen case main body 11. In other words, the second auxiliary member 32 is provided above the folding line L. Further, the third auxiliary member 33 is provided below the folding line L.

The sum of the vertical length dimensions of the second auxiliary member 32 and the third auxiliary member 33 substantially matches the vertical length dimension of the first auxiliary member 31. The second auxiliary member 32 is provided over the entire length of the folded-back region 18 in the vertical direction. The third auxiliary member 33 is provided over the entire length of the vertical length dimension of the portion of the pen case main body 11 other than the folded region 18. In this case, the term "over the entire length" means that it is 90% or more of the vertical length dimension of the folded region 18 or the vertical length dimension of the portion other than the folded region 18 of the pen case main body 11, respectively. means.

A gap S is formed between the second auxiliary member 32 and the third auxiliary member 33 provided on the outer surface side of the pen case main body 11. The gap S may be very small as long as the second auxiliary member 32 and the third auxiliary member 33 are discontinuous, that is, formed separately, and for example, the second auxiliary member 32 and the third auxiliary member 33 are in contact with each other. May be. The gap S between the second auxiliary member 32 and the third auxiliary member 33 can be set to, for example, 0.1 mm to 10 mm. For example, in this embodiment, the gap S is set to 1 mm.

As shown in FIGS. 3 and 4, the auxiliary member 30 is provided so as to be sandwiched between the inner sheet 111 and the outer sheet 112 of the pen case main body 11. Specifically, the first auxiliary member 31 is attached to the inner sheet 111. Further, the second auxiliary member 32 and the third auxiliary member 33 are attached to the outer sheet 112. In the present embodiment, the auxiliary member 30 is directly sewn to the pen case main body 11. In another embodiment, the auxiliary member 30 may be attached to the pen case main body 11 by, for example, an adhesive.

The auxiliary member 30 may integrally constitute the first auxiliary member 31, the second auxiliary member 32, and the third auxiliary member 33. That is, for the auxiliary member 30, for example, the portion other than the gap S has a thickness obtained by combining the first auxiliary member 31 and the second auxiliary member 32 or the third auxiliary member 33, and the gap S portion has the thickness of only the first auxiliary member 31. It can also be configured as.

Subsequently, the opening / closing mechanism of the pen case 10 will be described with reference to FIGS. 12 to 14. As shown in FIG. 12, when the pen case 10 is in the expanded state, that is, when the deforming member 20 is in the first state, the user can push the operation unit 17 in the direction perpendicular to the first surface 21. In this case, pushing in the vertical direction means that the external force applied by the user includes a vertical component. When an external force is applied to the end 23 of the deforming member 20 through the operating portion 17, the deforming member 20 changes to the second state. At that time, as shown in the intermediate state in FIG. 13, the pen case 10 is deformed by rolling inward the inner surface side of the pen case main body 11, that is, the side on which the accommodating portion 12 is arranged.

When the deforming member 20 is in the second state, as shown in FIG. 14, the pen case main body 11 has a cylindrical shape with the vertical direction as the axial direction. Then, the inner surface side of the pen case main body 11 including the accommodating portion 12 is caught inside and is not exposed to the outside. This tubular state is referred to as a closed state of the pen case 10. When the pen case 10 is in the closed state, the pen case 10 is held in the closed state without opening when there is no external force above a certain level due to the repulsive force of the spring of the deforming member 20. Further, in that case, the stationery 40 inside the accommodating portion 12 is held by the repulsive force of the spring of the deforming member 20.

When the pen case 10 is in the closed state, the user applies an external force sufficient to overcome the repulsive force of the spring of the deforming member 20 to the operation unit 17 or its vicinity in the radial outward direction, whereby the pen case 10 is again applied. Can be changed to the expanded state. At that time, the user can hold the left and right operating units 17 with both hands, for example, in a state where the pen case main body 11 is extended in the left-right direction to a certain length or more, that is, a deformable member 20 is extended in the longitudinal direction to a certain length or more. You may bend the pen case body 11 so that the inner surface side of the pen case body 11 is convex. By doing so, the user can stabilize the deforming member 20 in the first state and stably maintain the state in which the pen case 10 is deployed, that is, the state in which the pen case 10 is open.

The user can operate the operation unit 17 even in the folded state shown in FIG. When an external force is applied to the operation unit 17 in the folded state in the direction perpendicular to the first surface 21 of the deforming member 20, the pen case 10 has a tubular shape with the folded region 18 folded as shown in FIG. transform. In this case, the long stationery 40 accommodated in the accommodating portion 12 may protrude from the folded line L, that is, the upper end of the cylindrical shape. The cylindrical radius of the folded state shown in FIG. 15 is larger by the thickness of the folded area 18 than the closed state when the folded area 18 shown in FIG. 14 is not folded. Further, the vertical length dimension of the tubular shape in the folded state shown in FIG. 15 is only the vertical length dimension of the folded area 18 as compared with the closed state when the folded area 18 shown in FIG. 14 is not folded. It gets smaller. Therefore, when the pen case 10 is closed in the folded state, it becomes easy to stand on its own even when it is erected in the vertical direction, and it can be used as a pen stand.

According to the present embodiment described above, the pen case 10 includes a pen case main body 11 and a deformable member 20. The deformable member 20 is provided on the pen case main body 11, and is wound in a columnar shape with the plate-shaped longitudinal direction as the circumferential direction and the first state developed in the shape of a long plate by receiving an external force. It is configured so that it can be switched between the second state and the second state. The pen case main body 11 is deployed in a flat plate shape when the deforming member 20 is in the first state. Further, when the deforming member 20 receives an external force while the deforming member 20 is in the first state, the pen case main body 11 is automatically deformed into a cylindrical shape by the deforming member 20 in the second state.

According to this, in the state where the pen case main body 11 is unfolded in a flat plate shape, that is, the pen case 10 is unfolded, the user closes the pen case 10 by a simple operation of pushing the deforming member 20. can do. That is, according to this, the user can fold and roll the pen case 10 into a cylindrical shape with a simple operation. Further, the pen case 10 does not require a cam or a rotor and has a simple structure. Therefore, it is possible to provide a pen case that can be quickly opened and closed with a simple structure.

Further, the pen case main body 11 is formed in a long shape in one direction in the unfolded state. The deforming member 20 is provided at a position that passes through the center of the pen case main body 11 in the lateral direction and overlaps with the center line of the pen case main body 11 along the longitudinal direction.

According to this, the pen case 10 is automatically deformed into a cylindrical shape by providing the deforming member 20 at the center of the pen case main body 11 in the lateral direction without providing the upper and lower members for winding. It is possible. Therefore, it is possible to provide the pen case 10 which is automatically wound into a tubular state with a simple configuration.

Further, the pen case main body 11 includes an operation unit 17 provided at a position overlapping with the end portion 23 in the longitudinal direction of the deformable member 20. The operation unit 17 is configured to be distinguishable from parts other than the operation unit 17 in the pen case main body 11.

According to this, since the operation unit 17 is located at a position overlapping the end portion 23 of the deformable member 20, that is, at the end portion in the left-right direction of the pen case main body 11, it is easy for the user to access and the operability is improved. In addition, there is little possibility that the fingers are pinched or caught in the process of closing the pen case 10. Furthermore, since the operation unit 17 is configured to be distinguishable from the parts other than the operation unit 17 of the pen case main body 11, the visibility is further improved for the user and the operability is improved.

Furthermore, the pen case main body 11 is provided on the inner surface side along the longitudinal direction of the deformable member 20, and includes a plurality of accommodating portions 12 capable of accommodating the stationery 40 inside. The operation unit 17 is provided on the outside of the accommodating unit 12 in the longitudinal direction of the pen case main body 11.

According to this, a plurality of accommodating portions 12 are provided along the longitudinal direction of the deforming member 20, that is, the rotation direction when the pen case main body 11 changes from a flat plate shape to a cylindrical shape. That is, the longitudinal direction of the long stationery 40 accommodated in the accommodating portion 12 is directed in the lateral direction of the deforming member 20, that is, in the direction parallel to the axial direction of rotation. Therefore, when the pen case 10 is closed to form a cylinder or from a cylinder to a flat plate, the stationery 40 accommodated in the accommodating portion 12 is less likely to be caught, and a smooth opening / closing operation can be performed. Further, since the operation unit 17 is provided outside the accommodating unit 12, it is easy for the user to access and the operability is improved, and when the user accommodates the stationery 40 in the accommodating unit 12, the operation unit is erroneously operated. Never push 17. Further, if the accommodating unit 12 and the operating unit 17 are overlapped with each other, if the stationery 40 is housed in the accommodating unit 12 overlapping with the operating unit 17, it becomes difficult for the user to operate the operating unit 17. On the other hand, in the present embodiment, since the accommodating unit 12 and the operating unit 17 do not overlap each other, the stationery 40 accommodated in the accommodating unit 12 does not easily hinder the user's operation.

Further, the pen case main body 11 is a folded region 18 that is a region that does not overlap with the deforming member 20 and can be folded toward the outer surface side of the pen case main body 11 with a folding line L overlapping the side portion in the longitudinal direction of the deforming member 20 as a fulcrum. Further has.

According to this, the pen case main body 11 can be partially folded back to the outer surface side, so that it becomes compact and saves space when it is spread on a desk and used. Further, the folding line L, which is a fulcrum when the folding region 18 is folded back to the outer surface side, coincides with the side portion in the longitudinal direction of the deforming member 20. Therefore, the user can easily visually recognize the folding line L. Furthermore, since the pen case main body 11 and the deforming member 20 are made of different members, the folded line L can be easily recognized. That is, since the deformable member 20 is harder than the pen case main body 11 made of the sheet-shaped member, the folded line L is easy for the user to recognize as a response.

Furthermore, since the folded region 18 is a region that does not overlap with the deformed member 20, the deformed member 20 is on the inner surface side of the pen case main body 11, that is, on the front side of the paper surface in FIG. 11 with respect to the folded region 18 in the folded state. Located in. That is, the directions in which the first surface 21 of the deforming member 20 faces are the same in the state where the folded area 18 is not folded and the state where the folded area 18 is folded. Therefore, the rotation direction of the second state of the deforming member 20 does not change between the state in which the folded region 18 is not folded and the state in which the folded region 18 is folded. That is, even in the folded state, the deforming member 20 is in the second state so that the pen case 10 has a tubular shape with the inner surface side of the pen case main body 11, that is, the side provided with the accommodating portion 12 inside. Therefore, as shown in FIG. 15, if the pen case 10 is closed in a folded state to form a cylinder, the pen case 10 can stand independently in the vertical direction and can be used as a pen stand, further saving space.

If the accommodating portion 12 is provided in the folded-back region 18, the vertical direction of the accommodating portion 12 is inverted in the folded-back state, so that the opening of the accommodating portion 12 is located below. Therefore, the stationery 40 is likely to fall off from the accommodating portion 12, especially when it is used as a pen stand in a closed state.

On the other hand, each accommodating portion 12 is provided in a region of the pen case main body 11 different from the folded region 18. According to this, the accommodating portion 12 is located on the inner surface side of the pen case 10 even in the folded state. Therefore, in the folded state and the pen case main body 11 in the unfolded state, that is, in the flat state, all the accommodating portions 12 are on the inner surface side, so that the user's listability and usability are improved. Further, since the vertical direction of each accommodating portion 12 is not inverted even when the folded region 18 is folded back, the opening of the accommodating portion 12 is located upward, and the pen case main body 11 is used as a pen stand in a closed state. Even in this case, the stationery 40 is difficult to fall off.

Here, since the pen case main body 11 is made of a flexible sheet-like member, there is a possibility that the end portion in the left-right direction may be bent or bent. Then, when the left-right end portion of the pen case main body 11 is bent or bent, the deformation of the deforming member 20 is hindered by the bent or bent end portion of the pen case main body 11. As a result, it becomes difficult for the pen case main body 11 to switch from, for example, the state of being unfolded in the flat plate shape shown in FIG. 12 to the state of being wound in the shape of a cylinder shown in FIG.

On the other hand, the pen case 10 further includes an auxiliary member 30. The auxiliary member 30 is provided at each end of the pen case main body 11 in the longitudinal direction along the side of the pen case main body 11 in the lateral direction. Further, the auxiliary member 30 has flexibility that allows it to be bent, and has a rigidity higher than the rigidity of the pen case main body 11.

According to this, rigidity is added to the pen case main body 11 by providing auxiliary members 30 at the left and right end portions of the pen case main body 11 which is easily bent. Therefore, it is possible to prevent the left and right ends of the pen case main body 11 from being bent or warped. Further, since the auxiliary member 30 has flexibility that allows it to be bent, it is less likely to interfere with the user when folding back the folded region 18 of the pen case main body 11.

Further, the auxiliary member 30 is provided at each end of the pen case main body 11 in the longitudinal direction along the side of the pen case main body 11 in the lateral direction. The auxiliary member 30 has flexibility that allows it to be bent, and has a higher rigidity than the pen case main body 11. The auxiliary member 30 includes a first auxiliary member 31, a second auxiliary member 32, and a third auxiliary member 33. The first auxiliary member 31 is provided so as to straddle the folding line L. The second auxiliary member 32 and the 33rd are both provided without straddling the folding line L. The third auxiliary member 33 is provided on the opposite side of the second auxiliary member 32 with respect to the folding line L.

According to this, since a part of the auxiliary member 30, that is, the first auxiliary member 31, is provided so as to straddle the folded line L, the folded area 18 is bent at the folded line L when it is used without folding. It can be suppressed. On the other hand, since a part of the auxiliary member 30, that is, the second auxiliary member 32 and the third auxiliary member 33 are provided without straddling the folded line L, the user is less likely to have resistance when the folded area 18 is folded back. .. Since the auxiliary member 30 is formed in a thin plate shape, it does not easily affect the appearance of the pen case 10, and it does not easily become a resistance when the user folds the folded area 18.

Further, the second auxiliary member 32 and the third auxiliary member 33 are arranged in a straight line. That is, the second auxiliary member 32 and the third auxiliary member 33 are arranged in a straight line in the lateral direction of the pen case main body 11 in this case in the vertical direction with the folding line L interposed therebetween.

According to this, as compared with the case where the second auxiliary member 32 and the third auxiliary member 33 are arranged separately rather than on a straight line, the portion overlapping the arranged portion of the auxiliary member 30 of the pen case main body 11 is a straight line. It can be limited to a shape. Therefore, the influence on the appearance of the pen case 10 can be further suppressed.

Further, the first auxiliary member 31, the second auxiliary member 32, and the third auxiliary member 33 are arranged so as to be overlapped with each other. The first auxiliary member 31 is provided on the inner surface side of the pen case main body 11 with respect to the second auxiliary member 32 and the third auxiliary member 33. That is, the first auxiliary member 31 is provided on the inner sheet 111 side, and the second auxiliary member 32 and the third auxiliary member 33 are provided on the outer sheet 112 side.

According to this, since the auxiliary member 30 is provided in duplicate, more bending rigidity can be added as compared with the case where the same member is used without overlapping, and the left and right ends of the pen case main body 11 can be added. It is possible to further prevent the portion from being bent or warped. Further, when the folded region 18 is folded, the radius of curvature becomes smaller on the outer surface side than on the inner surface side of the pen case main body 11. Therefore, a larger bending stress is generated at the portion of the folding line L on the outer surface side than on the inner surface side of the pen case main body 11. In the present embodiment, the first auxiliary member 31 provided across the folding line L is provided on the inner surface side of the pen case main body 11, and the second auxiliary member 32 and the third auxiliary member 32 provided on the outer surface side of the pen case main body 11. None of the auxiliary members 33 straddle the folding line L. Therefore, it is less likely to be an obstacle when the user wraps the folded area 18.

Further, the first auxiliary member 31 is provided over the entire length of each end portion in the longitudinal direction, in this case, the left-right direction of the pen case main body 11. According to this, at each end of the pen case main body 11 in the left-right direction, the first auxiliary member 31 extends straight from the upper end to the lower end, and warping is suppressed.

In the above embodiment, the pen case main body 11 is formed in a rectangular shape with the longitudinal direction as the left-right direction, but is formed in a square shape in which the length dimension in the left-right direction and the length dimension in the vertical direction are substantially equal to each other. May be. Further, the pen case main body 11 may be formed in a rectangular shape whose longitudinal direction is the vertical direction. That is, the longitudinal direction of the pen case main body 11 and the longitudinal direction of the deforming member 20 do not necessarily have to match. Even in that case, the above-mentioned effect is achieved.

Further, in the above embodiment, one deformable member 20 is provided on the pen case main body 11, but the number of the deformable members 20 may be two or more. In that case, the force of the spring generated when the deforming member 20 is in the second state becomes stronger than in the case of one. Therefore, even if the size of the pen case body 11 is large or the stationery 40 housed in the pen case body 11 is thick or heavy, the pen case body 11 can be smoothly deformed into a tubular shape. After being deformed into a tubular shape, the stationery 40 can be reliably held.
