[0016] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. [Outline of the embodiment] The pen case (the present pen case) according to an embodiment of the present invention is a flat, box-shaped pen case having a bottom, a top, a front, side, a back, and a partition that divides the interior. It has a gusset that connects the top and the partition, and a connecting portion that connects the partition to the back end of the side. The back is connected to the bottom and top and also to the connecting portion. The gusset and connecting portion prevent the top from tipping toward the back when the top is open. When the top is closed, the gusset and connecting portion are stored inside. When closed, the pen case is thin and easy to carry. The tray-shaped storage compartment on the bottom has a large capacity, but pens do not easily overlap, making it easy to find the desired pen. When opened, the top remains tilted toward the back rather than vertical, preventing it from tipping over and allowing it to be placed stably. It can also be kept wide open, making it easy to take things in and out.

[0017] [Configuration of this pen case: Figures 1 to 8] The configuration of the pen case will be described with reference to Figures 1 to 8. Figure 1 is a perspective view of the pen case when closed, Figure 2 is a perspective view of the pen case when open, Figure 3 is a top view of the pen case, Figure 4 is a front view of the pen case, Figure 5 is a right side view of the pen case, Figure 6 is a left side view of the pen case, Figure 7 is a back view of the pen case, and Figure 8 is a bottom view of the pen case.

[0018] As shown in Figures 1 and 2, when closed, it is a flat, thin, notebook-style (box-shaped) pen case, and is equipped with a tray section 10, a lid section 20, and a partition section 30, with the tray section 10 and the lid section 20 connected by a zipper section 5 so that they can be opened and closed.

[0019] The tray section 10 is a storage section on the bottom side. The lid portion 20 is a portion that serves as a lid for covering the top of the tray portion 10 . In addition, the partition section 30 is provided inside the pen case as described below and divides the internal space, and is connected to the back section 3 and to the lid section 20 by a gusset section as described below.

[0020] Each part of this pen case will be explained. [Tray section 10] As shown in FIG. 2, the tray portion 10 has a flat box shape and includes a bottom portion 1, a side portion 2, and a back portion 3. As shown in FIG. 8, the bottom surface 1 is flat and has a substantially rectangular shape, with rounded corners on the front side.

[0021] One long side of the bottom surface portion 1 is connected to the back surface portion 3. In addition, the three sides of the bottom surface portion 1 that are not connected to the back surface portion 3 (one short side, the other long side, and the other short side) are connected to the side surface portion 2. In addition, a core material is provided inside the bottom surface portion 1. In this way, the bottom surface 1 of the present pen case has a flat structure equipped with a core material, and can maintain a stable posture so that it does not tip over to the rear side even when the lid 20 is opened.

[0022] As shown in FIGS. 4, 5 and 6, the side surface portion 2 includes a front side surface portion 2a, a right side surface portion 2b and a left side surface portion 2c, which are integrally formed to form the band-shaped side surface portion 2. The front side surface portion 2a corresponds to the front surface portion described in the claims, and the right side surface portion 2b and the left side surface portion 2c correspond to the side surfaces described in the claims. The side surface 2 of the pen case is rounded so that the corners on the front side are curved to match the shape of the bottom surface 1. The corners on the front side are the connection part between the front side surface 2a and the right side surface 2b, and the connection part between the front side surface 2a and the left side surface 2c.

[0023] As shown in FIGS. 1 and 2, three sides of the bottom surface portion 1, excluding the side connected to the back surface portion 3, are connected to the lower end of the side surface portion 2 by a piping-like edge portion 6a. One long side of the fastener part 5 is attached to the upper end of the side part 2 . The fastener 5 is a slide fastener equipped with a moving slider 51.

[0024] 7, the rear surface 3 has a rectangular shape similar to that of the front surface 2b shown in FIG. 4, but is not curved. One short side of the rear surface 3 is connected to the right surface 2b by an edge 6b, and the other short side is connected to the left surface 2c by an edge 6d. The length of the short sides of the side surface 2 and back surface 3 is set to, for example, about 3.5 cm so that the thickness (height) of the entire pen case is 4 cm or less. Furthermore, no core material is provided inside the back surface portion 3.

[0025] 2, one end of connecting portions 7a and 7b that connect the side surface portion 2 to the back surface portion 3 and the partition portion 30 is fixed to the short side of the side surface portion 2. The connecting portions 7a and 7b may be collectively referred to as the connecting portion 7. When the fastener 5 is fully opened, the back surface 3 opens flat to the same surface as the bottom surface 1. When the fastener part 5 is closed, the connecting parts 7a and 7b are folded and stored inside the pen case.

[0026] [Lid part 20] The lid portion 20 also has a top surface portion 4 that is flat. As shown in Fig. 3, the top surface portion 4 has a generally rectangular shape similar to the bottom surface portion 1, and the corners on the front side are rounded, which allows the slider 51 of the fastener portion 5 to move smoothly at the corners on the front side.

[0027] One long side of the top surface portion 4 is connected to the back surface portion 3, and the other long side of the fastener portion 5 is attached to three sides of the top surface portion 4 excluding the side connected to the back surface portion 3. The top surface portion 4 and the fastener portion 5 are connected by a piping-shaped edge portion 6c. The top surface portion 4 is provided with a core material inside, similar to the bottom surface portion 1.

[0028] As shown in Figures 1 and 2, the edge 6a of the tray portion 10, the edge 6b of the back portion 3, the edge 6c of the lid portion 20, and the edge 6d of the back portion 3 are formed continuously to form the edge 6. The edge 6 improves the design and also reinforces the connections of the various parts.

[0029] [Partition 30] The partition section 30 divides the interior of the pen case, and is a roughly rectangular shape that is slightly smaller than the top surface section 4, with rounded corners at the top. One long side of the partition section 30 is connected to the back surface section 3, and both short sides are fixed to the inside of the top surface section 4 by the gusset sections 31.

[0030] The gusset portion 31 is rectangular in shape with two oblique sides, an upper side (top side), and a lower side (bottom side), with one oblique side (long side) connected to the inside of the top surface portion 4 and the other oblique side connected to the short side of the partition portion 30. As a result, the space surrounded by the top surface 4, the partition 30, and the gusset 31 forms a pocket 33, which can store small items. By making the shape of the gusset 31 a square with a bottom side rather than a triangle, the pocket 33 has depth and a larger capacity, making it easier to store small items with a three-dimensional shape.

[0031] Furthermore, since the gusset portion 31 is formed up to a portion close to the upper edge of the partition portion 30, small items in the pocket 33 can be prevented from falling out from the side. When the fastener portion 5 is closed, the gusset portion 31 is folded inward and stored inside the main body.

[0032] Furthermore, a mesh pocket 34 is provided on the side of the partition 30 facing the bottom surface 1. The mesh pocket 34 allows the contents to be seen, making it convenient for storing thin and small items. That is, this pen case has three storage sections: the tray section 10, the pocket 33, and the mesh pocket .

[0033] [Configuration of the connecting part: Figure 9] Next, the configuration of the connecting portion 7 of the pen case will be explained using Figure 9. Figure 9 is an explanatory diagram showing the configuration of the connecting portion of the pen case. Figure 9 shows the left side of the pen case in an open state, and the connecting portion 7b is outlined in white to make it easier to understand. As shown in FIG. 9, the connecting portion 7b connects the side surface portion 2 and the partition portion 30, and is connected to the short side of the side surface portion 2, the back surface portion 3, and the partition portion 30.

[0034] In the example of Figure 9, the right side of connecting portion 7b is connected to one of the short sides of side portion 2, and the bottom side of connecting portion 7b is connected to about 2 / 3 of the short side of back portion 3, closer to side portion 2. The left side of the connecting portion 7b is fixed to the rear side of the partition portion 30 (the surface facing the top surface portion 4, inside the pocket 33), and the top side is open. Although not shown, the connecting portion 7a on the right side surface has the same configuration.

[0035] One oblique side of the gusset portion 31 is connected to the inside of the top surface portion 4, and the other oblique side is connected to the short side on the back side of the partition portion 30. Furthermore, the lower side of the gusset portion 31 is connected to the 1 / 3 portion of the short side of the back portion 3 that is not connected to the connecting portion 7b.

[0036] Also, as shown in Figure 9, on the left side surface, the end of one long side of the fastener portion 5 is fixed to the end of the side portion 2 closer to the back surface, and the end of the other long side of the fastener portion 5 is fixed to the lower end of the top portion 4. On the other hand, on the right side, one long side of the zipper part 5 protrudes from the end near the back of the side part 2, and the other long side is attached and connected so as to protrude from the lower end of the upper part, and has a play (room) part that is not fixed to the main body, allowing the zipper part 5 to be opened wide enough.

[0037] [Cover 20 open: Figure 2] Next, the state in which the lid 20 of the pen case is open will be described with reference to FIG. When the fastener 5 of this pen case is fully opened and the lid 20 is opened, the lid 20 remains tilted toward the rear side rather than vertically as shown in FIG. 2 and stands upright. This is because the length of the connecting portions 7a, 7b connecting the partition portion 30 and the side portion 2, and the angle formed by the two oblique sides in the gusset portion 31 connecting the partition portion 30 and the top portion 4 (the angle formed by the intersection of the extension lines of the two oblique sides, and the degree to which the two oblique sides are open) are adjusted so that the lid portion 20 remains at that angle.

[0038] In this pen case, the lid portion 20 remains in an inclined position even when there are no pens or the like in the tray portion 10, but by placing pens or the like in the tray portion 10, the position becomes even more stable. As a result, when closed, the pen case has a thin box shape, making it easy to carry, and when the fastener section 5 is fully opened, the lid section 20 can be held in an open position toward the back rather than vertically, allowing the pen case to maintain a stable position on a desk, making it easy to see the contents of the tray section 10 and pockets, and making it easy to take pens and small items in and out.

[0039] [Effects of the embodiment] According to the embodiment of the present invention, the pen case is a flat box-shaped pen case, and includes a bottom portion 1, a top portion 4, a front side portion 2a, a right side portion 2b, a left side portion 2c, a back portion 3, and a partition portion 30 that separates the interior. A gusset portion 31 connects the top portion 4 and the partition portion 30, and a connecting portion 7 connects the partition portion 30 to the rear end of the side portion 2. The back portion 3 is connected to the bottom portion 1 and the top portion 4, and also to the connecting portion 7. The gusset portion 31 and the connecting portion 7 are connected to each other when the top portion 4 is open. When the top part 4 is closed, the gusset part 31 and the connecting part 7 are stored inside, and when the top part 4 is closed, it is thin and easy to carry, the tray-like storage part on the bottom side has a large capacity, and the pens do not easily pile up, making it easy to find the desired pen, and when the top part 4 is opened, it can be placed stably in a state where it is tilted towards the back rather than vertical, and it can be kept in a wide open state, making it easy to take things in and out.

[0040] In addition, with this pen case, the tray portion 10 is flat and plate-shaped, so it can store a large number of pens and other items, and the contents are less likely to overlap, making it easier to find the desired pen.Furthermore, the lid portion 20 is provided with two pockets, so small items can be stored in a categorized manner.
