Abstract

(57) [Summary] [Purpose] After transplanting a plant transplanted into a seedling raising container into an open field and cultivating it, the container is not damaged when excavating the container from the soil and it can be pulled out without labor. And [Structure] A handle portion was integrally provided on the upper edge of a pot-shaped seedling-growing container having a molded nonwoven fabric strength of 20 kg / 5 cm, which was obtained by hot-press molding a needle-punched nonwoven fabric with an uneven mold.

Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a seedling raising container used for raising seedlings of vegetables, flowers, ornamental plants, trees and the like.

[0002]

[Prior Art]

 Conventionally, containers such as unglazed pots and plastic pots have been generally used as seedling raising containers, but the former are expensive, heavy and easily cracked. The latter is light, but has problems such as poor ventilation and water permeability.

For this reason, in recent years, in order to take advantage of the lightweight, porosity, and water permeability characteristics of the non-woven fabric, a non-woven fabric formed by sewing or thermocompression molding into a pot shape has been used.

[0004]

[Problems to be solved by the device]

 The porosity and air permeability of such a non-woven pot exerts an excellent effect on the growth of plants, but it is buried in soil for rearing, and after growth, it is pulled out from the soil and shipped. However, the resistance of the soil may cause the plants to fall out and damage the roots of the plants or damage the container, so remove the soil around the container and dig it out, or dig the whole with a scoop. It has to be raised and it takes time to dig out.

[0005]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention eliminates the soil around the upper part of the container at the time of shipping or transplanting by integrally providing the handle part on the upper edge of the nonwoven fabric seedling container, and Provide a nursery container that can be easily dug out without damaging the roots of the plant by pulling it out by hand.

The handle portion provided in the seedling raising container of the present invention is not limited to its shape and design, and it is preferable that at least one pair is provided on the diagonal line of the upper end edge in view of its workability and efficiency. It is also desirable to make the continuous part of the container body as wide as possible.

[0007] The strength of the molded seedling-growing container needs to be at least 20 kg / 5 cm or more when it is buried in the soil and needs to be pulled out without being broken at the handle part or the continuous part with the container when it is pulled out. I need.

The non-woven fabric used to mold the seedling raising container may be a composite of synthetic resin nets such as saran, vinyl chloride, polyethylene, polypropylene, polyamide, etc., meshes, etc., depending on the application, size, or required strength. It is possible to prevent damage to the container or handle when pulling it out of the soil by increasing the strength of the container as a whole by increasing the strength of only the upper edge and the handle of the container.

[0009]

[Action]

 When performing open-field cultivation of plants using the container for raising seedlings of the present invention, most of the container is embedded in soil to grow seedlings, flowers, etc. Instead, you only have to pull out the container handle, and the digging work is simple and easy, and no labor is required. Moreover, the plant with the container extracted is shipped or transplanted as it is.

[0010]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is an inclined view showing an example of the implementation of the present invention. As shown in the figure, the nonwoven fabrics constituting the nursery container 1 of the present invention are dry nonwoven fabrics, wet nonwoven fabrics, spunbonded nonwoven fabrics, melt blown nonwoven fabrics, It is selected and used from jet bond non-woven fabric, needle punched non-woven fabric, etc.

[0012] For example, a crossweb of a basis weight of 130 g / cm ² formed by using a mixed fiber of 70:30 of polyester fiber and polyester-based heat-bonded composite fiber (Melty 4080 manufactured by Unitika Ltd.), and needle punch of 150 P / cm ² The processed non-woven fabric was used.

This non-woven fabric is thermoformed by a concavo-convex mold at a mold temperature of 120 ° C., a compression pressure of 2.5 tons and a compression time of 23 seconds, and the strength of the non-woven fabric after molding is 22 kg / 5 cm in width. Was formed. A cut 3 which is horizontal in the circumferential direction and horizontal from the left and right is made in the required length in the upper edge 2 of the obtained seedling raising container, and it is raised upward from the left and right to form the handle 4 and the handle 4 is integrally provided. The seedling raising container 1 of the present invention was constructed.

In the above examples, only synthetic fibers (including heat-bonded composite fibers) were used as the non-woven fabric fibers, but natural fibers, semi-synthetic fibers, regenerated fibers, etc. may be mixed and used. Various fibers and fabrics having a basis weight can be used according to the type of the non-woven fabric to be used and are not limited to the examples.

FIG. 2 is a perspective view of another embodiment of the present invention. As shown in FIG. 2, the same needle-punched non-woven fabric 5 as shown in FIG. 1 is used as the base non-woven fabric, and one surface is made of polypropylene for reinforcement. The composite non-woven fabric fused with the mesh sheet 6 is thermoformed by an uneven mold to form a pot-shaped seedling raising container. The upper edge is cut off to form a pair of left and right ear-shaped handles 4 integrally. Then, the seedling raising container of the present invention was constructed. The synthetic resin mesh sheet for reinforcement may be provided above the middle of the container.

[0016]

[Effect of the device]

 By adopting the above-mentioned configuration, the present invention makes it possible to easily dig up by raising the seedling container, which is mostly embedded in soil for vegetation, by pulling it with the handle part, resulting in remarkable work efficiency. Improved and less labor. Moreover, even if there is a possibility that the strength of the non-woven fabric may decrease due to aging of the plant for a long period of time due to the combination with the synthetic resin net and mesh, there is no damage due to the decrease in strength, and the extraction work can be performed reliably. It is a device that has practical effects such as implementation.
