Description

[Technical Field]

[0001] This invention relates to a pen case with an inner case that makes it easy to see the contents stored inside from the outside. [Background technology]

[0002] As described in Patent Document 1, pen cases that use see-through materials to allow the inside to be seen have existed for some time. Patent Document 1 discloses that the inside can be seen by using a transparent body made of vinyl chloride.

[0003] Although it is possible to make the inside visible by using a material made of vinyl chloride, a pen case that allows for easier visibility is needed because many writing implements are often stored in layers. Moreover, since pen cases are often placed in the position on a desk farthest from the user, there is a need for a pen case that allows for even easier visibility.

[0004] Furthermore, in pen cases, writing implements often fall to the bottom of the storage space, and there is a demand for pen cases that are easy to use, such as ones that allow the contents stored in the storage space to be easily visible and are less likely to be damaged.

[0005] [Patent Document 1] Registered Utility Model Publication No. 3101278 Summary of the Invention [Problem to be solved by the invention]

[0006] Therefore, the purpose of this invention is to provide a pen case that allows high visibility of the inside and is also easy to use. [Means for solving the problem]

[0007] In order to solve the above problems, the present invention provides a pen case with an inner case having an opening and closing mechanism and an internal storage space, The pen case has a first window portion that can be seen through on the front portion, The inner case is capable of being housed in the housing space and is characterized by including an engaging member that maintains the inner case in an exposed engaged state in which a part of the inner case is exposed from within the housing space.

[0008] The pen case also has a partition that divides the storage space into a first storage space on the first window side and a second storage space that can accommodate an inner case made of a see-through material, The inner case preferably has an engaging member that engages with the partition.

[0009] The partition preferably has a second window portion through which the partition can be seen.

[0010] Preferably, the first window and the second window are made of a PVC material, and the inner case is made of a mesh fabric.

[0011] Moreover, it is preferable that the first window portion be fixed to a frame portion that surrounds the front portion. [Effects of the Invention]

[0012] According to the invention of claim 1, not only can the interior be seen, but by having an engaging member on the inner case inside the storage space, it is possible to open the pen case and keep the inner case exposed, so even if the pen case is filled with various items, the interior can be easily seen through the first window, and the contents inside the inner case can be seen. This makes it possible to provide a pen case with high interior visibility and ease of use.

[0013] According to the invention described in claim 2, the inner case is stored in the second storage space at the rear separated by the partition, and in the exposed engagement state, the engagement part engages with the partition, enabling stable engagement. Furthermore, since the inner case is made of a see-through material, writing implements and other items inside the inner case, which are partially exposed in the exposed engagement state, can be easily seen.

[0014] According to the invention described in claim 3, by forming a second window portion in the partition portion, it is possible to see not only the storage items stored in the first storage space but also the storage items stored in the second storage space, and it is also possible to easily see the writing instruments that have fallen below the inner case in the exposed engagement state.

[0015] According to the invention described in claim 4, the second window portion and the inner case are capable of coming into contact with each other, and if both were made of PVC resin they would come into close contact. However, by using different materials for the second window portion and the inner case, the resins do not come into close contact, and the inner case can be easily separated.

[0016] According to the invention described in claim 5, by having a frame around the periphery, the PVC resin can be used without being bent, preventing damage to the PVC resin and providing a pen case that is easy to use. [Brief explanation of the drawings]

[0018] An example of an embodiment of the present invention will be described with reference to the drawings. As shown in Figures 1-3, the pen case 1 of this embodiment is configured so that an inner case 30 can be stored inside while being engaged in a partially exposed state. In this description, the direction from the front portion 11 to the back portion 12 will be referred to as the front and rear, and the direction from one side portion 13 to the other side portion 13 will be referred to as the left and right.

[0019] As shown in Figures 1-5, the pen case 1 of this embodiment is made of a sewn soft material (polyester fabric) except for a window portion, which will be described later, and has a front portion 11, a back portion 12, side portions 13, a flat portion 14, and a bottom portion 15. It has an opening / closing mechanism 2 that runs from the bottom end of one side portion 13 through the flat portion 14 to the bottom end of the other side portion 13, and by opening and closing the opening / closing mechanism 2, it is possible to store writing implements and other items in the internal storage space 3. Note that the material of the pen case 1 of this embodiment is not limited to polyester fabric, and may also be nylon fabric or fiber such as cotton.

[0020] The opening and closing mechanism 2 of this embodiment is a zipper with a slider, and has a tape portion and an element portion on the flat portion 14 and both side portions 13, 13. Note that the opening and closing mechanism 2 is not limited to a zipper, and may be a button or other mechanism.

[0021] In the pen case 1 of this embodiment, the ratio of the front-to-rear length of the flat surface 14 to the front-to-rear length of the bottom surface 15 is approximately 1:3, and the pen case 1 has a trapezoidal shape with a short upper side when viewed from the side (see FIG. 4(b)). When viewed from the side, the front surface 11 and the back surface 12 form inclined surfaces that slope inward from the bottom surface 15 toward the flat surface 14. Therefore, the storage space 3 is wider on the bottom surface 15 side than on the flat surface 14 side.

[0022] Although not shown, a polypropylene core material is inserted inside the bottom portion 15 to prevent the bottom portion 15 from deforming. Also, a cushioning material may be placed on the back portion 12. Furthermore, in this embodiment, both the front portion 11 and the back portion 12 are inclined trapezoidal shapes when viewed from the side, but it is also possible to have only the front portion 11 inclined and the back portion 12 standing at a substantially right angle from the bottom portion 15 as a right-angled trapezoid.

[0023] In this embodiment, the front portion 11 has a surrounding frame portion 11b that forms the outer edge of the front portion 11, and a first window portion 11a in the center. The first window portion 11a is made of transparent soft PVC resin, allowing the interior to be seen from the outside. The first window portion 11a is sewn to the surrounding frame portion 11b, and the frame portion 11b has a folding position that forms the boundary between the side portions 13, 13, the flat portion 14, and the bottom portion 15. This configuration prevents cracks and other problems that can occur when the PVC resin is folded and used continuously.

[0024] The pen case 1 of this embodiment has a first window portion 11a on the front portion 11, and the first window portion 11a is arranged on an inclined surface so that it has a trapezoidal shape when viewed from the side.Therefore, even when the user places the pen case at a distance from the desk, the state of the storage space 3 can be seen from an obliquely upward position, making it particularly easy to see the lower part of the storage space.

[0025] Next, we will explain the storage space 3 of the pen case 1 of this embodiment. The storage space 3 is made up of gusset sections 20, 20 arranged in positions close to the side sections 13, 13 on both sides, and a partition section 21 that spans between the gusset sections 20, 20 (see FIG. 5(b)).

[0026] The gusset portions 20, 20 are strip-shaped members sewn at the boundary between the side portion 13 and the back portion 12 and at the boundary between the side portion 13 and the front portion 11, and are not sewn between the flat portion 14 and the bottom portion 15, and are free from the bottom portion 15. By having the gusset portions 20, 20, a constant opening and closing width (front-to-back width) can be maintained even when the opening and closing mechanism 2 is fully open.

[0027] The partition 21 has one side connected to one gusset portion 20 and the other side connected to the other gusset portion 20, and separates the storage space 3 into front and rear. The partition 21 is also connected only to the gusset portions 20, 20 by sewing, but is not connected to the flat portion 14 and the bottom portion 15, and is particularly free from the bottom portion 15. The partition 21 has a second window portion 21a made of hard PVC resin, and the upper and lower sides form a frame portion 21b that appears to be bordered by a soft material (polyester fabric) (see Figures 1 and 3).

[0028] The storage space 3 separated by the partition 21 consists of a first storage space 3a on the side of the first window 11a between the front portion 11 and the partition 21, and a second storage space 3b between the partition 21 and the back portion 12. In this embodiment, the partition 21 is located slightly forward of the center position in the front-to-rear direction of the gusset portions 20, 20, so the second storage space 3b is larger than the first storage space 3a. In this embodiment, the inner case 30 is stored in the second storage space 3b.

[0029] As shown in Fig. 7, in a second embodiment, the divider 21 may be located in the center of the gusset portions 20, 20 in the front-to-rear direction, in which case the first storage space 3a and the second storage space 3b are substantially the same area. Furthermore, although the divider 21 in this embodiment is rectangular, the frame portion 21b below the divider 21 may be curved so as to be convex downward. Because the divider 21 is separated from the bottom surface portion 15, writing implements and the like may move from the first storage space 3a to the second storage space 3b, but by making the frame portion 21b below the divider 21 curved, such movement can be suppressed.

[0030] Next, the inner case 30 will be described with reference to Figures 1-3 and Figure 6. The inner case 30 is a bag-shaped object made of mesh fabric, and the periphery of the upper opening 31 is bordered with a soft material (polyester fabric). The inner case 30 has a folded-over portion of the mesh fabric as the bottom, and the sides are internally bordered and sewn together, and the mesh fabric is used not only for the front portion 33 and back portion 34 but also for the bottom portion 35, making it possible to see inside.

[0031] The inner case 30 also has a pocket 36 made of separate mesh fabric sewn to the bottom and sides on the inside surface of the back portion 34. The pocket 36 is sewn along its upper edge 36a, which is located below the opening (upper edge) 31 of the inner case 30 (see FIG. 1).

[0032] The dimensions of the inner case 30 are such that the left-right length is shorter than the left-right length between the gusset portions 20, 20 on both sides of the storage space 3 of the pen case 1, the up-down length is approximately the same as the length from the inner surface of the bottom portion 15 to the upper edge of the partition portion 21, and the front-to-rear length is shorter than the front-to-rear length of the second storage space 3b. Therefore, the inner case 30 can be stored in the second storage space 3b.

[0033] The pen case 1 has a first window 11a in the front part 11, and also a second window 21a in the internal partition part 21. Therefore, when the inner case 30 is stored in the second storage space 3b, the user can visually check the first window 11a, the second window 21a, and the storage state inside the inner case 30 made of mesh fabric from the outside.

[0034] As shown in Fig. 6, the inner case 30 has an engaging body 40 disposed on the front face portion 33. The engaging body 40 in this embodiment is a vertically long, belt-like member sewn to the center of the front face portion 33. The engaging body 40 has a fixing portion 41, at least the edge of which is sewn to the front face portion 33 at the center in the up-down direction, an engaging portion 42 extending downward from a lower edge 41a of the fixing portion 41 with its lower end being a free end, and a gripping portion 43 extending upward from an upper edge 41b of the fixing portion 41 with its upper end being a free end.

[0035] The exposed engagement state in which the inner case 30 is engaged and held in an exposed state from the pen case 1 will now be described. First, from the stored state of the inner case 30 shown in Fig. 2(a), the opening / closing mechanism 2 of the pen case 1 is opened (Fig. 2(b)), and the inner case 30 stored in the second storage space 3b as shown in Fig. 1 is removed. At this time, removal is facilitated by pinching the grip portion 43 of the engagement body 40. Next, as shown in Fig. 3, the engagement portion 42 of the engagement body 40 is inserted into the center position of the partition portion 21, so that the inner case 30 can be held in a partially exposed state from the pen case 1.

[0036] In this way, the inner case 30 can be brought into the exposed engagement state shown in Fig. 3 by inserting and engaging the engagement portion 42 of the engagement body 40, which has a predetermined left-right width, into the partition 21. In this case, the center position of the upper edge of the partition 21 becomes the engaged portion that engages with the engagement body 40. However, the form of the engagement body is not limited to that of this embodiment, and other engagement forms such as buttons or hooks may also be used.

[0037] In this embodiment, the second window 21a is made of hard PVC resin. If the inner case 30 were also made of PVC resin, there is a risk that the inner case 30 and the second window 21a would stick together due to heat or other factors. However, by making the inner case 30 out of mesh fabric, this PVC resin sticking can be prevented, allowing for smooth storage and removal. Note that, as in this embodiment, it is preferable to make the first window 11a and the second window 21a out of PVC resin and the inner case 30 out of mesh fabric, but this is not necessarily a limitation. For example, the first window 11a and the second window 21a may be made of EVA resin, or the inner case may be made of a different material.

[0038] Furthermore, when the inner case 30 is in the exposed engagement state, the bottom surface 35 of the inner case 30 is located near the center of the partition portion 21 in the vertical direction, the upper edge 36a of the pocket 36 is located above the frame portion 11b of the front portion 11, and the opening 31 of the inner case 30 is also located at an even higher position.

[0039] Pen case 1 generally stores not only writing implements but also small items such as erasers, which can fall to the bottom. Because the lower edge of inner case 30 is made of a folded portion of mesh fabric, small items that have fallen near the lower edge can be easily seen. In addition, inner case 30 also has pocket 36 for storing small items with a bottom that is higher than bottom portion 35. For example, if sticky notes or the like are placed in pocket 36 so that they are partially exposed, when inner case 30 is in the exposed engagement state, items stored in first storage space 3a can be seen through first window 11a, items below inner case 30 can be seen through first window 11a and second window 21a, and items above inner case 30 can be seen from the exposed state.
