In general, there is a desire to place a plant in the surrounding environment, watch its growth, and keep calm and calm. on the other hand,
If there is anything that makes you think about plants in your desk work during your daily study or work, it will improve your work efficiency. Conventionally, as a simple plant cultivation method, in Japanese Utility Model Registration No. 3016542 and Japanese Utility Model Application Laid-Open No. 6-68402, a postcard-size seed-containing sheet containing plant seeds within the thickness of a paper sheet is grounded. It has been proposed to germinate by burying in the burial.

[0003]

However, the above-mentioned seed-enclosed paper sheet has to be buried by digging the ground with a scoop or the like. Was not. Moreover, since the thickness of the paper sheet was about 3 mm, the culture soil could not be included together with the seed, and the germination rate was particularly low when the paper sheet was buried outdoors.

The present invention has been made in view of the above-mentioned conventional problems, and has as its object the purpose of being able to use a writing instrument while feeling close to a plant, and to simply bury the trunk by piercing the trunk after use. An object of the present invention is to provide a pen-shaped plant cultivator capable of germinating and growing plant seeds by operation.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a preferred first embodiment of the present invention will be described with reference to the accompanying drawings. The pen-shaped plant incubator of the present invention is a device having a function as a writing instrument and capable of germinating a plant simply by penetrating and embedding it in soil when writing is completed. As shown in FIGS. 1 to 4, the pen-shaped plant incubator 10 of the present embodiment has a pencil shape having a body 12 and a writing part 14.

[0010] The body 12 has a hollow interior, and an accommodation chamber 16 for accommodating a plant seed s or a culture soil m in which the plant seed s is mixed is formed in the hollow. The body 12 of the present embodiment is an elongated hollow cylinder, and has a cylindrical hollow portion inside. The cylindrical hollow portion is used as the accommodation room 16 to accommodate the culture soil m in which the seeds s of the plant are mixed. A writing portion 14 is fixed to one end side (lower side in FIG. 1) of the hollow cylinder so as to form a single pencil, and the other end side (upper side in FIG. 1) is closed by a cap 18. The accommodation room 16 is hermetically sealed so that the seeds s and the culture soil m are accommodated while being shielded from the outside air.

The body 12 is made of paper having a certain thickness. This paper material is a soil-decomposable material that disappears with time in the ground. When the paper is put in the soil for a certain period of time, it absorbs the moisture in the soil and releases the bonding force of the internal tissues,
Dissolves and disappears. When the time has elapsed since the trunk 12 was buried in the ground, the wall of the trunk 12 disappeared and the culture soil m contained therein.
And the seed s becomes continuous with the surrounding soil.

The writing unit 14 of the present embodiment is a pencil whose core 20 and wooden shaft 22 are reduced by use of writing. The wooden shaft 22 has a solid cylindrical shape having substantially the same diameter as the outer diameter of the body 12. The upper end surface 22a is a circular flat surface having substantially the same diameter as the outer diameter of the donut-shaped lower end surface of the body portion 12. The upper end surface 22a is abutted to the lower end of the body 12 with the same outer diameter, and is adhesively fixed. The wooden shaft 22 is integrated into a single column that is continuous with the body 12 in the same axial direction.

A core 20 is embedded at the center of the wooden shaft 22 along the axial direction. The wick 20 is a cylindrical pencil wick thinner than the wooden shaft body, and the wooden shaft body 22 is embedded below the upper end surface 22a, which is abutted with the body 12, at a predetermined distance below. With the use of writing, the core and the wooden shaft are shaved and reduced, and when the core and the wooden shaft are shaved to the position shown by the dashed line in FIG. 2, the core 20 disappears. This signals the end of writing, and prevents the wooden shaft 22 from being scraped until the culture soil m spills out. Although the core 20 of this embodiment uses a normal carbon core, a color core kneaded with a pigment may be used.

On the outer peripheral surface near the joint where the writing part 14 is joined to the lower part of the body part 12 in a single columnar shape, a paper sleeve 24 is laid over the body part 12 and the writing part 14. It is wound around and adhered. By bonding the upper side of the sleeve 24 to the peripheral side of the lower end of the body 12 and the lower side to the peripheral side of the writing part 14, the fixed connection strength between the body 12 and the writing part 14 is increased. The paper material forming the sleeve 24 is also made of a soil-decomposable material. However, when used as a writing instrument, the material is adjusted so as not to dissolve by sweat or the like even if it is gripped for a long time.

A cap 18 closing the upper end of the body 12 opposite to the writing section 14 is made of a transparent synthetic resin. As shown in FIGS. 1 and 3, the cap 18 has a short quadrangular prism shape, and a hole 26 for fitting the upper end of the body 12 at a required depth is provided in the center of the lower surface of the square. The cap 18 is fitted to the upper end of the body portion 12 by using a weak adhesive together with the hole 26. The cap 18 having a rectangular shape in a plan view prevents the pen-shaped plant incubator 10 from rolling when placed on a desk.

Here, the operation of the present embodiment will be described with reference to FIGS. The writing section 14 of the pen-shaped plant incubator 10 having the initial shape in which the writing section 14 as shown in FIG.
The side is scraped in the same manner as a regular pencil, and the lead 20 is exposed and used as a writing implement. With the use of writing which is cut every time the lead 20 is worn, the number of pencils serving as the writing unit 14 decreases. As shown in FIG. 4, the use as a writing instrument is terminated when the core 20 is gone. The remaining pen-shaped plant breeding machine 10 can be easily stabbed in the ground with the sharp wooden shaft 22 down on the ground and tapping or stepping on the cap 18 side.

Next, the cap 18 is removed and water is applied in an amount necessary for germination of the plant. Then, the culture soil m and the surrounding soil contained in the body 12 contain sufficient moisture, and the body 12
Is dissolved from inside and outside. Plant seeds germinate,
By the time the root is set, the body 12 is sufficiently weakened and is torn by the force of the root. As the time elapses, the pen-shaped plant incubator 10 embedded in the ground is also decomposed by microorganisms in the ground and completely disappears.

In the present embodiment, the culture soil m in which the plant seeds s are mixed is accommodated in the accommodation room 16, but only the plant seeds s may be accommodated. Further, the sealing of the end portion of the body portion 12 other than the writing portion 14 side is not limited to the use of the cap, and the body portion 18 may be formed in a bottomed cylinder whose upper end is also covered with the same material as the side wall. Then, the sheet may be covered with easily tearable paper. Further, the material of the body 12 and the sleeve 24 is not limited to a paper material, but may be a biodegradable plastic, or may be a material obtained by binding starch extracted from potato, corn, or the like.
