Description

  The present invention relates to a paper airplane formed of origami or drawing paper. More particularly, it relates to a paper airplane with plant seeds attached.

Conventionally, paper airplanes have been manufactured by folding origami such as Japanese paper, color foil, plastic film, or by cutting and pasting color drawing paper, work paper, cardboard paper, and the like.
However, when playing with these paper airplanes, if the paper airplanes land in remote areas such as forests or other people's gardens, they will not be able to be collected by the person who flew, and will be left as garbage. There was a problem.
Therefore, in the field of origami, which is a material for paper airplanes, origami made of a plastic film using a degradable plastic as a main raw material has been proposed (see, for example, Patent Document 1).
Since the origami shown in Patent Document 1 is made of a polylactic acid plastic film, it is hydrolyzed by temperature and humidity under certain conditions, and then is enzymatically decomposed by microorganisms and finally decomposed into carbon dioxide gas and water. In particular, under high temperature and high humidity as in the soil, the degradation of polylactic acid proceeds rapidly, so that origami can be decomposed into carbon dioxide gas and water within one week, and there is little possibility of adversely affecting the environment.
JP 2004-166828 A (Claim 1, Claim 2, Paragraphs [00015], [0016], [0017], [0018], FIG. 1)

However, when a paper airplane made using the origami disclosed in the above-mentioned conventional patent document 1 is skipped and the paper airplane lands in a place where a person cannot enter, such as a mountain forest, the biodegradability of the origami Thus, although the paper airplane is finally decomposed into carbon dioxide and water, it was not possible to germinate a new plant at the landed place and to make flowers bloom.
The object of the present invention is to form a biodegradable sheet, and attach plant seeds to the front of the trunk, so that it does not become garbage even if it is landed in an unrecoverable place after flying and left unattended. The object is to provide a seeded paper airplane that allows seeds to take root and bloom.
Another object of the present invention is to provide a seeded paper airplane that can optimize the flight balance by using plant seeds as a weight or part of a weight.

The invention according to claim 1, as shown in FIGS. 5-7, a body 51, and a main blade 52 and tail 53, and the body 51, the main blade 52 and tail 53 are biodegradable sheet 13 It is an improvement of the formed paper airplane.
The characteristic structure is that the body 51 includes a core paper 51a having a hole 51c formed in the front portion, and a pair of thin papers 51b bonded to both surfaces of the core paper 51a. The plant seed 15 is inserted into the hole 51c and sandwiched between the pair of thin papers 51b so that the plant seeds 15 are attached to the front of the trunk 51 .
In the seeded paper airplane according to claim 1, the plant seed 15 is attached to the front part of the fuselage 51 , so that it can be used as a weight, and the flight balance of the paper airplane 50 is optimized. be able to. The paper airplane 50 made of the biodegradable sheet 13 is hydrolyzed at a temperature and humidity satisfying certain conditions, and then is decomposed into carbon dioxide gas and water through an enzymatic decomposition by microorganisms to return to the natural environment circulation system. Only the plant seeds 15 attached to the paper airplane 50 are finally left, and some of them can be rooted in the soil and bloom with flowers.
Further, by inserting the plant seeds 15 into the holes 51c of the core paper 51a and sandwiching them between the pair of thin papers 51b, the plant seeds 15 can be attached to the body 51 without using the water-soluble seal 16. If the plant seed 15 is attached to the trunk 51 by the water-soluble seal 16, the attachment strength of the plant seed 15 to the trunk 51 can be further improved.

The invention according to claim 2 is the invention according to claim 1, seeds 15 further in plants, characterized in that mounted in the water seal 16 to the front of the fuselage 51.
In the seeded paper airplane according to the second aspect, the plant seeds 15 are pasted to the front of the fuselage 51 with the water-soluble seal 16, so that the paper airplane 50 left in a mountain forest or another person's garden is exposed to wind and rain. As a result, the water-soluble seal 16 is melted, and the plant seeds 15 can be detached from the paper airplane 50 and quickly fall to the ground or the like before the paper airplane 50 is naturally decomposed.

The invention according to claim 3, an invention according to claim 1 or 2, further to the weight of the seeds 15 the plant is, of the weight of the paper airplane excluding the seeds 15 of the plant 3 minutes at 1 or less It is characterized by being.
In the seeded paper airplane according to claim 3 , the plant seed 15 attached to the front of the trunk 51 is changed by changing the weight, size, number, or type of the plant seed 15 itself. The weight balance can be optimized by setting the weight of the paper airplane to 1/3 or less of the weight of the paper airplane itself. As a result, the flight distance of the seeded paper airplane 50 can be extended.

  As described above, according to the present invention, since the seed of the plant is attached to the front part of the fuselage of the paper airplane, this seed can be used as a weight. At this time, the weight, size, number, or seed type of the plant seed can be changed to finely adjust the weight of the weight, and the flight balance of the paper airplane can be optimized. As a result, the flight distance of the paper airplane can be extended. Moreover, since the paper airplane was formed with the biodegradable sheet, it is decomposed into carbon dioxide gas and water through hydrolysis and the like after hydrolysis. As a result, the paper airplane can fly and land in a forest or another person's garden and cannot be recovered. Even if the paper airplane is left as it is, it does not become garbage and can be returned to the circulatory system of the natural environment. Furthermore, since only the seeds of plants remain after the paper airplane biodegrades, these seeds can take root in the soil and bloom flowers.

Next, the best mode for carrying out the present invention will be described with reference to the drawings.
< Reference form>
As shown in FIGS. 1 and 2, the paper airplane 10 includes a fuselage 11 and a triangular wing 12. The body 11 and the triangular wing 12 are formed by folding the biodegradable sheet 13.
As the biodegradable sheet, it is preferable to use a sheet that is substantially maintained in a folded state when folded and that quickly decomposes when left in a forest or the like. Specifically, biodegradable sheets include biomax (biodegradable plastic made of a polyester copolymer manufactured by DuPont), laceia (polylactic acid resin manufactured by Mitsui Chemicals), and MDP (wood manufactured by Mishima Paper Co., Ltd.). Water-soluble paper made of pulp with improved dispersibility) or so-called eco paper or Japanese paper made from sugar cane (bagasse). Moreover, it is preferable to use the sheet | seat which has not passed the chlorine bleaching process from a viewpoint of environmental pollution prevention.

  A plant seed 15 is attached to the front of the body 11. Here, the plant refers to flowering plants, foliage plants, and food among seed plants. Specific examples include potato wheel grass and cosmos. A weight portion 17 is formed at the front portion of the body 11 by folding the biodegradable sheet 13. That is, the seed 15 of the plant is configured to be enclosed in the weight part 17. Specifically, first, the biodegradable sheet 13 is folded several times to form a substantially home base shape as shown in FIG. Next, after seeds 15 of two plants are placed at the front portion of the body 11 of the sheet 13, these seeds 15 are fixed to the sheet 13 with water-soluble seals 16, respectively. Next, the part which becomes the front part of the trunk | drum 11 of the sheet | seat 13 is folded so that the said seed 15 may be wrapped. (FIG. 3B). Further, the desired paper airplane 10 is obtained by folding the sheet 13. The seed 15 together with the weight portion 17 serves as a weight for maintaining the flight balance of the paper airplane 10. In addition, about the joint line of the folding | folding of the sheet | seat 13, when folding the sheet | seat 13 along the target fold line, it is good to make a 0.5-2 mm gap between the sides combined with a fold line. If the sides of the broken line are aligned too closely, when the broken line becomes a valley fold, a part of it folds up, and the paper folds down and the performance of the paper airplane deteriorates. Further, it is preferable that the name of the seed 15 of the plant, for example, “arrow car grass” is displayed on the surface of the sheet 13 when the paper airplane 10 is produced by folding the sheet 13 (FIGS. 2 and 4). ).

The operation of the paper airplane configured as described above will be described.
First, since the plant seed 15 is attached to the front portion of the body 11 of the paper airplane 10, the seed 15 can be used together with the weight portion 17 as a weight. At this time, the weight of the plant seeds 15 can be finely adjusted by changing the weight, size, number, or seed type of the seeds 15 and the flight balance of the paper airplane can be optimized. it can. As a result, the flight distance of the paper airplane can be extended. Further, since the seed 15 is fixed to the sheet 13 with the water-soluble seal 16, the granular seed 15 can be attached to the sheet 13, and even if the fold of the sheet 13 is opened during the flight of the paper airplane 10, the seed 15 It does not fall from the paper airplane 10.

  Further, since the paper airplane 10 is formed by the biodegradable sheet 13, the paper airplane 10 is hydrolyzed at a constant temperature and humidity, and then decomposed into carbon dioxide and water through enzymatic decomposition by microorganisms. As a result, the paper airplane 10 can be skipped and landed in a forest or other person's garden and cannot be recovered. Even if the paper airplane 10 is left as it is, it does not become garbage and can be returned to the circulatory system of the natural environment. Furthermore, since only the seed 15 of the plant remains after the paper airplane 10 is biodegraded, several percent of the seed 15 is rooted in the soil, so that the leaves and flowers grow in the vicinity where the paper airplane 10 has landed. It can bloom and bear fruit. Further, by limiting the plant seeds 15 to be attached to the paper airplane 10 to the same native species as the vegetation of the nearby mountain forest where the paper airplane 10 is flying, the balance of the ecosystem is not lost. Further, when the paper airplane 10 has landed in another person's garden, the owner of this garden sees the characters “Yowah Grass” displayed on the surface of the paper airplane 10, and the weight portion 17 of the paper airplane 10 is shown in FIG. As shown, by filling the soil 18 in the garden, the probability that the seed 15 will take root is further increased.

In the form of the above Symbol reference, but to display the name of the plant on the surface of the paper airplane, may display a sentence such as "with seeds, by returns to the soil."
<Embodiment of the present invention >
5-7 show an embodiment of implementation of the present invention.
In the present embodiment, the seeded paper airplane 50 includes a fuselage 51, a main wing 52, and a tail wing 53. The body 51, the main wing 52, and the tail wing 53 are all formed of a biodegradable sheet. As shown in FIG. 5, the body 51 is formed in the same shape as the core paper 51a by a pair of core paper 51a having a hole 51c formed in the front portion and a sheet that does not have the hole 51c and is thinner than the core paper 51a. It consists of a pair of thin paper 51b. As shown in FIG. 6, the core paper 51 a has a straight back side to which the main wing 52 and the tail wing 53 are attached. The front surface of the core paper 51a is formed in an arc shape, and the hole 51c is formed so as to be substantially located at the center of the arc of the front end surface of the core paper 51a.
The diameter of the hole 51c and the depth of the hole 51c when the facing surfaces of the pair of core papers 51a are bonded with glue or the like are 2-3 mm larger than the diameter of the plant seed 15 accommodated in the hole 51c, respectively. It is formed. Thereby, the attachment operation | work of the seed 15 to the core paper 51a can be performed smoothly.

Subsequently, the thin paper 51b is stuck on both surfaces of the core paper 51a to which the plant seeds 15 are attached using glue or the like. As a result, the hole 51c to which the seed 15 is attached is closed and the seed 15 is sandwiched between the pair of thin papers 51b, so that the seed 15 is not detached from the paper airplane 50. In this way, the body 51 is formed. In addition, a substantially triangular projection 51 a extending downward is provided at the front portion of the body 51. The front part of the fuselage 51 including the projections 51 a becomes the weight part 57, and the seed 15 becomes a weight for maintaining the flight balance of the paper airplane 50 together with the weight part 57.
Next, the main wing 52 is attached to the center in the longitudinal direction on the back side of the fuselage 51. The main wing 52 is integrally formed so that a substantially semi-elliptical portion is line-symmetric about the fuselage 51. The main wing 52 is bonded to the approximate center of the back side of the fuselage 51 with glue or the like. Lifting force is obtained by the main wing 52, and a paper airplane can be blown. Subsequently, a tail 53, in this case, a horizontal tail 53 is attached to the rear end of the trunk 51 on the back side. The horizontal tail 53 is formed smaller than the main wing 52, and is adhered to the body 51 with glue or the like in the same manner as the main wing 52. Furthermore, it is preferable to display the name of the seed 15 of the plant, for example, the letters “Yowah Grass” on the surface of the main wing 52 (FIGS. 6 and 7).

In the paper airplane 50 configured as described above, the weight of the weight can be finely adjusted by changing the number and size of the seeds 15 of the plant. As a result, the flight balance of the paper airplane 50 can be optimized, and the flight distance of the paper airplane 50 can be extended. Further, since the thickness of the core paper 51a and the diameter of the hole 51c can be changed according to the number and size of the seeds 15 to be accommodated, a spherical three-dimensional seed 15 can also be attached.
Further, when the paper airplane 50 has landed in another person's garden, the owner of the garden sees the characters “Yowah Grass” displayed on the main wing 52 of the paper airplane 50, and the weight portion 57 of the paper airplane 50 is shown in FIG. As shown in FIG. 5, by burying in the soil 58 of the garden, the probability that the plant seeds 15 are rooted in the soil 58 is further increased.
In the embodiment of the above Symbol present invention has been to display the name of the plant to the wing, may display a sentence such as "with seeds, by returns to the soil."
Furthermore, although the paper airplane which attaches a plant seed to a sheet | seat was described in the said reference form and embodiment of this invention , you may produce a paper airplane using the Japanese paper which extracted the plant seed beforehand.
