Abstract

PROBLEM TO BE SOLVED: To provide a flowerpot having reduced water-permeability but good air-permeability, and a comparatively light weight, and capable of making the flowerpot from a paper waste and a plastic waste. SOLUTION: This flowerpot is characterized in that the flowerpot has a first water-absorbing paper layer part for forming the inner surface, a second water-absorbing paper layer part for forming the outer surface, and a water- absorbing mixed layer part arranged between the first and the second water- absorbing paper layer parts, and including a pulverized product of the plastic waste, a pulverized product of the paper waste and a water-absorbing resin, and the side part and the bottom part are composed of the plate member integrally formed by joining the first and the second water-absorbing layer parts and the water-absorbing mixed layer part. As a result, the number for watering can be reduced because, even when the water in the flowerpot is reduced by evaporation or the like, the water is supplemented by the water absorbed and held by the highly water-absorbing resin in the wall body of the flowerpot, and the root rot of a plant is prevented by air, especially oxygen having penetrated the wall body and invaded into the flowerpot because the outer face is formed out of the water-impermeable and air-permeable film.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flowerpot, and more particularly, to a flowerpot.
The present invention relates to a flowerpot made of paper having water absorbency and / or water retention, paper waste material water absorbent resin and plastic waste material.

[0002]

2. Description of the Related Art Flower pots are used for growing and commercializing plants, and are made of unglazed, pottery and plastic materials. When a plant is grown using a flower pot, an appropriate amount of potting soil is put in the flower pot, the plant to be planted is planted in the soil, and the plant is grown by giving appropriate sunlight, temperature and humidity. The potting soil used for the flowerpots has good drainage, water retention and air permeability, and can hold the given fertilizer well, and is preferably clean.

[0003]

However, unglazed flower pots tend to lose water in the soil because the walls are highly permeable, and if the water is not watered relatively frequently, the flower pots in the flower pots cannot be planted. Since water withering occurs, it is not possible to leave the machine for a relatively long time, which is a problem. In addition, unglazed and pottery pots are relatively heavy and, moreover, are liable to be broken by impacts such as dropping. On the other hand, plastic flower pots are light and relatively flexible, so that they are less likely to be damaged by impacts such as dropping, and are convenient for transportation. However, because it is made of plastic, the wall does not have air permeability like pottery, and accordingly, water does not leak out from the wall of the pot, and the water holding is better than unglazed flower pots However, since water in the soil remains in the flower pot for a relatively long time and tends to rot, the plant is likely to cause root rot in the flower pot, which is a problem. An object of the present invention is to solve the problems of watering and transporting conventional flowerpots made of plastic, pottery and unglazed.

In the present invention, in order to produce a water-retaining flowerpot at low cost, the content of the plastic waste material used in the water-absorbing mixed layer portion is larger than the content of the paper waste material. can do. In the present invention, the upper water-absorbing paper layer portion, the lower water-absorbing paper layer portion, and the plastic absorbent provided between the upper and lower paper layer portions, the water-absorbing material containing the paper waste material and the water-absorbing resin The mixed layer portion is pressure-molded into an embossed and bendable plate member. It is preferable to use a foldable plate member because the assembly of the flower pot becomes easy.
In the present invention, an intermediate water-absorbing paper layer can be provided between the inner and outer water-absorbing paper layers. When the water-absorbing paper layer has three layers as described above, the inner first water-absorbing mixed layer can be formed between the inner first water-absorbing paper layer and the intermediate water-absorbing paper layer.

In the present invention, the flowerpot is provided with a first water-absorbent paper layer on the inside and a second water-absorbent paper layer on the outside. In the present invention, it is preferable to use a water-permeable thin layer to which an insect repellent is applied, since the pests can be controlled during use. Further, in the present invention, when the biodegradable plastic material waste material is used for the water-impermeable thin layer portion and the water-permeable thin layer portion of the biodegradable plastic material, and the water-absorbing mixed layer portion, the biodegradable plastic material is buried in the ground for each flower pot. It is preferable because it can be buried in vegetation soil and disposed of. In the present invention, the inner first water-absorbing paper layer, the outer second water-absorbing paper layer, and the intermediate third water-absorbing paper layer are formed of tissue paper such as absorbent paper, water-absorbent paper or crepe paper. Is preferable because good water absorption can be ensured. In the present invention,
As the water-absorbing paper, a composite paper produced by dispersing pulp and chemical fibers in a liquid and making paper can be used. For example, a composite paper having water absorbency or water permeability, which is obtained by laminating chemical fiber paper such as polypropylene chemical fiber paper to thin paper, can be used.

The resulting pulp-rich classified product can be used.

In the present invention, when a defective sanitary material such as a defective paper diaper, a milk pad, a hip pad or a sanitary napkin is used as the paper waste material of the water-absorbing mixed layer portion,
Since it contains a plastic material, paper powder, and a water-absorbent resin, the amount of pulverized plastic waste material and superabsorbent resin added during the production of a flowerpot can be reduced, and the mixing operation can be simplified, which is preferable. As described above, cutting waste generated during the production of sanitary materials, and waste materials such as so-called dust collection loss in which dust generated during cutting is collected contain paper powder of plastic material and pulp material powder. It can be used as a mixture of pulverized plastic waste material and pulverized paper waste material. Since the cutting waste or dust collection loss generated during the production of these sanitary materials has a small content of the water-absorbent resin or the superabsorbent resin, it is necessary to add and mix the water-absorbent resin or the superabsorbent resin.

In the present invention, the board member forming the flower pot has a water-absorbing paper layer portion formed of thin paper such as water-absorbing paper on each of the inner side and the outer side. Thin paper such as water-absorbing paper is, for example, tissue paper having a basis weight of 12.5 g / m ² , and can be disposed on the inner side and the outer side, respectively. In the present invention, the water permeability means a property that allows water to permeate. For example, a certain amount (25 ml) of water is reduced to 2 in 20 seconds or less.
It is determined by the time (seconds) required for the entire amount of water to permeate when injected into a cm circle. A shorter permeation time is more excellent in water permeability than a longer one. In the present invention, printing can be performed on the inner surface and / or outer surface of the water-absorbing paper or plastic film, and the name, display, advertisement, and / or usage method can be displayed. When a pH check ink is used as the printing ink, the wetness and dryness of the soil can be displayed from the place where the color of the ink becomes lighter as the ink dries, and the pH indicator is used as a pH indicator.
By selecting the discoloration range of the indicator that matches the pH range of the plant grown in the flower pot, it is possible to check whether the pH of the soil is the pH of the soil suitable for the plant to be grown. In addition, since the pH value of the soil can be displayed, the management of growing trees is facilitated. For most plants, the optimal pH range for nutrient absorption is 6.0-7.0, so the pH indicator or pH-mix indicator has a discoloration range of 6.0 on the acidic side and a neutral range of 7.0. Is preferred. An example of such an indicator is bromothymol blue.

In the present invention, a highly water-absorbing resin is blended in the water-absorbing mixed layer in order to maintain the water retention in the flowerpot. The superabsorbent resin used in the present invention is preferably a resin that can retain its shape even when it absorbs water about 30 to 100 times its own weight with water. Examples of such superabsorbent resins include saponified copolymers of vinyl esters and ethylenically unsaturated carboxylic acids or derivatives thereof, graft polymers of starch and acrylic acid, crosslinked products of polyacrylic acid, and vinyl alcohol. And acrylic acid, a partially hydrolyzed product of polyacrylonitrile, a crosslinked product of carboxymethylcellulose, a crosslinked product of polyethylene glycol, a chitosan salt or a gel of pullulan. These are used alone or in combination of two or more of them in the water-absorbing mixed layer portion. In the present invention, it is preferable to use a so-called superabsorbent resin having high water absorbability as the water absorbent resin to be contained in the water absorbent mixed layer portion, since the amount of use can be reduced.

In the present invention, the term water-absorbent resin also means a water-absorbent resin having a lower water-absorbing ability than a higher-water-based resin, in addition to a higher-water-based resin. In the present invention, when a crushed material of only waste paper diaper waste material including plastic waste material, pulp waste material and water absorbent resin waste material is used in the water-absorbing mixed layer portion of the flower pot, the superabsorbent resin is contained in the flower pots 14 to 28. % By weight, and high water retention can be maintained. In the present invention, as the superabsorbent resin, for example, a superabsorbent resin-containing material recovered from waste paper diapers can be used. Such a recovered regenerated superabsorbent resin has a water absorption capacity of 10 to 30 g / g with water, which is poor in water absorption performance.
