Description

[Detailed description of the device]

[0001]

[Industrial field of application] The present invention relates to a water supply core used for a plant cultivation container. More specifically, for potted plants, the soil in the pot and an external aquarium are connected to supply water from the outside of the pot bottom. The present invention relates to a columnar water wicking body having a function of supplying water to the soil in the wick.

2. Description of the Related Art In order to reduce the labor required for irrigation in pot cultivation of plants, many methods such as a lumbar irrigation method, a bottom water irrigation method, a tube irrigation method, and a bottom water supply method have been proposed and used. Among them, in the bottom surface water supply method, a method of using a water absorbing member such as a water absorbing string and sucking water into the soil in the pot to supply water by utilizing the capillarity has been proposed from an early stage.

For example, in Japanese Examined Patent Publication No. 38-5214, a sheet material having a capillarity is interposed between the soil in the pot and the wall of the pot, and the sheet material and the water in the water tank provided under the pot are placed. A method is disclosed in which water is supplied to the soil in the pot by communicating through a hole at the bottom of the pot.

In this method, a substance also having a capillarity is used as a connecting material, that is, a water absorbing body. That is, the water absorbent body is a string-like material having a high water absorbing property, and is generally flexible and has no so-called rigidity, and it takes much time to attach the water absorbent body to the bowl, and it is far less detachable.

It has been proposed to solve the drawbacks of the bottom surface water supply system using a string or the like, for example, a holder for a water suction body as shown in Japanese Patent No. 521862. This uses a holder that can be attached to and detached from the hole at the bottom of the pot, and while holding the water wicking body, attach and detach to the hole at the bottom of the pot to supply water to the soil in the pot. It is a thing. The method of using the holder of the water suction body is epoch-making in that the water suction body can be freely attached and detached, but on the other hand, a special constituent member called a holder is required, Further, it also has a defect that the shape of the hole at the bottom of the bowl has to be special.

[0006]

DISCLOSURE OF THE INVENTION The problem of the present invention is that the above-mentioned holder is not necessary, and a removable water which is directly pushed (inserted) into the soil in the pot through the hole at the bottom of the ordinary pot. It is to provide a wicking body.

DISCLOSURE OF THE INVENTION The present invention is a fiber bundle in which all the fibers are bundled in the vertical direction, in which a corrosion-resistant fiber having hydrophilicity and a heat-fusible fiber are mixed. , 30% or more of hydrophilic corrosion-resistant fibers and having an apparent specific gravity of 0.1 g / cm ³ or more, and mainly heat-bonding the heat-fusible fibers on the surface of the fiber bundle As a result, the problem of the conventional water supply core was solved by forming the columnar structure with a hardness that allows it to be inserted into the soil in the plant cultivation container.

Since the water core of the present invention is directly inserted into the soil and is used for a long period of time while always containing water in that state, sufficient corrosion resistance is required. Therefore, it suffices if it is composed of 100% corrosion resistant fibers, but if the mixing ratio of non-corrosion resistant fibers does not exceed 70%, that is, if the corrosion resistant fibers do not become lower than 30%, The point is also satisfactory.

Secondly, in the present invention, the apparent specific gravity is 0.1 g / c.
It is necessary to be m ³ or more, which is important as a requirement for controlling the water supply capacity to the soil in the plant cultivation container (pot), that is, the water absorption property. In other words, the columnar fiber aggregate having an apparent specific gravity of less than 0.1 g / cm ³ is unsatisfactory in terms of its ability to feed water into the soil in the pot, that is, its water uptake ability, and it is not suitable for the growth of potted plants. This is because it is insufficient as irrigation water.

Thirdly, the present invention requires that the surface of the columnar fiber assembly has a hardness that allows it to be pushed into the soil in the pot. The function of the columnar fiber assembly of the present invention is, in addition to the water wicking function, another important function is the attachment / detachment function by directly inserting and pulling out from the pot bottom hole into the soil in the pot. The surface hardness of the aggregate is
It is indispensable as a requirement to make full use of this function. In other words, the surface hardness of the columnar water core for plant cultivation containers of the present invention must be sufficient to withstand pushing into soil in the pot in order to exert the function of pushing into and removing it from the soil in the pot. The purpose of the present invention cannot be achieved. The hardness is not imparted to the surface of the columnar fiber assembly, and when it is soft, from the pot bottom hole,
Since it cannot be directly pushed into the soil in the pot, it is not suitable as the water core of the present invention.

The surface hardness can be improved by increasing the apparent specific gravity of the fiber accumulation, but in the present invention, the heat-meltable synthetic fiber is mixed in the accumulated fiber to form the columnar aggregate. This is a column in which the heat-melting synthetic fibers mainly mixed in the surface portion are heat-fusion bonded to increase the hardness of the column. The fiber accumulation state of the columnar fiber assembly of the present invention is not particularly limited as long as its apparent specific gravity and surface hardness are satisfied, but all fibers are arrayed and focused in the vertical direction. is there. In other words, in such a fiber accumulation state, even if the surface hardness is increased by a means of increasing the apparent specific gravity of the fiber accumulation, no difficulty occurs in the water wicking speed.

The present invention will be described in more detail with reference to the drawings. FIG. 1 is a partially cutaway perspective view of a columnar water supply core 1 for a scepter cultivation container according to the present invention, in which aggregate fibers 2 are all bundled in a state of being directed in a vertical direction A, and are put into soil in a pot. A cylindrical fiber assembly having a surface 3 having a hardness capable of being pushed is formed. In this case, it does not necessarily have to be cylindrical, and for example, elliptical column, square column,
It may be a pentagonal column or the like. FIG. 2 is a schematic cross-sectional view showing one embodiment in the case of using the columnar water supply core for a plant cultivation container of the present invention to supply water into soil in a pot. That is, the water 7 is sucked up and supplied by the columnar water core 1 for a plant cultivation container which is directly pushed into the soil 6 in the pot 5 through the pot bottom hole 4. The hardness of the columnar water core 1 for a plant cultivation container, that is, the surface 3 of the fiber assembly is important in terms of direct pushing into the soil 6 in the pot 5.

[Effects of the Invention] The water supply core of the present invention can be used for watering potted plants through the water supply core only by pushing (inserting) it into the soil through the hole at the bottom of the pot and putting the tip of the pot outside the water. It has an excellent function of being able to do, and is extremely effective in simplifying watering to potted plants.
