  Embodiments will be described below with reference to the accompanying drawings.

(First embodiment)
FIG. 1 is a perspective view of a pen case 10 according to the present embodiment.

  As shown in FIG. 1, a pen case 10 according to this embodiment includes a cylindrical main body 1 and a lid 2 that closes an opening at the upper end of the main body 1, and a writing instrument is provided in the main body 1. It is the structure which accommodates.

  The main body 1 and the lid portion 2 are formed of a flexible elastomer having elasticity, and are easily deformed when an external force is applied, and are restored to the original shape when the force is removed. As the elastomer, for example, a silicone resin can be used. Moreover, if the thickness of the main body 1 and the lid portion 2 is, for example, 1 mm to 4 mm, elasticity suitable for the pen case 10 is obtained.

  The main body 1 includes a narrowed portion 12 and a bottom portion 13 of a cylindrical portion 11 that are integrally connected. Among these, the cylindrical part 11 occupies most of the main body 1 and extends downward in a cylindrical shape with a constant outer diameter. From the lower end part of the cylindrical part 11, the narrowing part 12 formed so that an outer diameter becomes small is extended as it goes below. Further, a bottom portion 13 constituting the bottom of the main body 1 extends from the lower end of the narrowed portion 12. The bottom portion of the bottom portion 13 is formed by a flat surface, and can be placed with the main body 1 standing on a desk or the like.

  The writing instrument housed in the main body 1 is supported from below by the bottom 13 when installed vertically.

  In the form of FIG. 1, the height from the bottom surface of the bottom portion 13 to the upper end portion of the cylindrical portion 11 is set to about 15 cm, which is the length of a general writing instrument such as a pen or pencil. The stored writing instrument is in a state of being hidden inside the main body 1.

  The lid portion 2 is attached to the upper end of the cylindrical portion 11 of the main body 1 via a flexible connecting portion 16. The connecting portion 16 is made of, for example, cloth and is stitched to the main body 1 and the lid portion 2 made of elastomer.

  The width of the connection portion 16 is preferably 20 mm or less. When the width of the connection portion 16 is wider than this, the lid portion 2 is gradually closed by the elastic restoring force of the connection portion 16 after the lid portion 2 is opened, and finally the lid portion. 2 closes. Therefore, if the width of the connecting portion 16 is too wide, it is necessary to hold the lid portion 2 by hand when putting in and out the writing instrument, and the usability is deteriorated.

  Further, from the viewpoint of preventing the above problems, the elastic restoring force of the connection portion 16 may be weakened by using a soft cloth for the connection portion 16.

  A wire fastener 15 is sewn to the lower end of the lid portion 2 other than the connection portion 16 and the upper end of the main body 1.

  By closing the wire fastener 15, the pen case 10 is sealed and the housed writing instrument can be carried.

  In the present embodiment, the lid portion 2 includes a side wall 2a having a height of about 2 to 3 cm (reference numeral E in FIG. 2) and a flat surface 2b at the upper end. For this reason, in addition to the height D of the main body 1 (about 15 cm), the overall height of the pen case 10 is about 1 cm which is the width of the wire fastener 15 and the height E (2 to 3 cm) of the lid 2. It becomes about 18-19cm added. As a result, writing instruments and rulers that are longer than usual can be accommodated with a margin.

  2 is a cross-sectional view of the pen case 10 of FIG. 1, and FIG. 3 is a cross-sectional view of the pen case 10 of FIG.

  As shown in FIG. 2, the pen case 10 of the present embodiment is formed to be thinner than other portions between the narrowed portion 12 and the tubular portion 11 so as to be easily deformed and to bend easily. One folding hinge 12a is formed.

  In addition, a second bent hinge 12b is formed between the bottom portion 13 and the narrowed portion 12 so as to be thinner than other portions and easily bent.

  The first bent hinge 12a formed between the tubular portion 11 and the narrowed portion 12 has a groove shape cut from the outside of the tubular portion 11 and the narrowed portion 12, as shown in the enlarged sectional view in the drawing. Is formed. When a force for pressing the restricting portion 12 upward is applied to the first bending hinge 12a, the restricting portion 12 is deformed so as to be bent in the direction indicated by the arrow A in the drawing.

  The second bent hinge 12 b formed between the narrowed portion 12 and the bottom portion 13 is formed in a groove shape cut from the inside of the main body 1. When a force in a direction of pressing the bottom portion 13 upward is applied to the second bending hinge 12b, the second bending hinge 12b is deformed in the direction indicated by B in the drawing.

  In the pen case 10 of the present embodiment, the first bent hinge 12a and the second bent hinge 12b are bent so that the portions of the narrowed portion 12 and the bottom portion 13 are accommodated inside the cylindrical portion 11. Transforms into

  That is, in the state of FIG. 1, when the cylindrical part 11 is held by hand and the bottom part 13 is pressed against a desk or the like, the first folding hinge 12a and the second folding hinge 12b are bent as shown in FIG. .

  As a result, as shown in FIG. 3, the narrowed portion 12 is folded back inside the tubular portion 11, and the bottom portion 13 is deformed to be accommodated inside the tubular portion 11.

  In the process of deforming from the shape of FIG. 2 to the shape of FIG. 3, a slight force is required because the diaphragm 12 bends, but after the deformation to the shape of FIG. The shape is maintained.

  At this time, the position of the bottom surface of the bottom portion 13 is substantially the same height as the first bent hinge 12 a at the bottom of the cylindrical portion 11 and becomes a part of the bottom of the main body 1. As a result, when the pen case 10 is erected, the pen case 10 is grounded to a desk or the like with a large area on the bottom surface, so that the pen case 10 can be stably made to stand by itself.

  FIG. 4 is a perspective view showing a state in which the pen case of FIG. 1 is deformed.

  By performing the above-described deformation as shown in FIG. 3, the position of the bottom surface of the bottom portion 13 moves to the upper end side of the main body 1, and the writing instrument 99 accommodated in the main body 1 is lifted by the bottom portion 13. Thereby, as shown in FIG. 4, the upper part of the writing instrument 99 protrudes from the upper end of the main body 1, and the writing instrument 99 can be easily taken out when the pen case 10 is used upright.

  The height at which the writing instrument 99 is lifted by the bottom 13 is substantially equal to the height C in FIG. This height can be set to, for example, 20 mm to 40 mm, which is the distance from the pen tip of the writing instrument 99 to the grip.

  If the height C is set to be larger than the above range, when the pen case 10 is deformed, the narrowing portion 12 is not smoothly folded back inside the cylindrical portion 11, and can be easily deformed. It becomes impossible.

  When returning from the configuration of FIG. 4 to the configuration of FIG. 1, the bottom portion 13 of the pen case 10 may be pinched by hand and pulled out from the tubular portion 11.

  As described above, the pen case 10 according to the present embodiment can be transformed into a pen stand by simply holding the cylindrical portion 11 of the main body 1 with one hand and pressing the bottom portion 13 against a desk or the like. Thereby, it can deform | transform easily from the form suitable for carrying the writing instrument 99 to the form which holds the writing instrument 99 upright.

  The pen case 10 according to the present embodiment is suitable for a user who works in a place where there are many opportunities to move frequently, such as a free address office where employees do not have individual desks.
