[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a flowerpot made of synthetic resin.

[0002]

[Prior art]

 2. Description of the Related Art Conventionally, there is a flowerpot made of synthetic resin such as polypropylene as a flowerpot.

[0003]

[Problems to be solved by the device]

 However, synthetic resin flower pots are actually lighter than pottery flower pots, and also have the problem that they do not look heavy or look good. Although it is possible to increase the overall weight of a synthetic resin flower pot by forming the upper edge and the lower end to be thick, in such a case, the plant pot lacks stability.

Further, the synthetic resin flower pot has a problem that the growth of the plant is inferior to the pottery flower pot because the flower pot is generally inferior in air permeability. The present invention has been made in view of such circumstances, and an object thereof is to provide a flowerpot made of a synthetic resin and having a feeling of weight and a high quality. Another object of the present invention is to provide a flowerpot which is made of synthetic resin and has excellent air permeability.

[0005]

[Means for Solving the Problems]

 The flowerpot of the present invention is made of a resin composition in which 50 to 80% by weight of a thermoplastic resin, 20 to 50% by weight of granular silica sand of 20 to 30 mesh, and 3 to 5% by weight of rubber are uniformly mixed. And are characterized. It is preferable to use coated sand as the silica sand.

Further, the flowerpot of the present invention is characterized in that a large number of holes having a diameter of 0.5 to 2 mm are formed in the side peripheral wall.

[0007]

[Action]

 Since the flowerpot of the present invention is made of a resin composition in which silica sand is mixed, the flowerpot is actually heavier than the conventional synthetic resin flowerpot, and also looks and feels heavy. Therefore, even if a large number of holes are formed in the side wall of the flowerpot of the present invention, the flowerpot has a stable feeling and can be provided with air permeability.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows an embodiment of the flower pot of the present invention, which is integrally molded with a resin composition in which a synthetic resin, silica sand, and synthetic rubber are mixed. The shape of the flower pot is not limited to that shown in FIG.

The synthetic resin is not particularly limited, and polyolefins such as polypropylene, polyethylene, and polystyrene, thermoplastic resins such as (meth) acrylic resin, and thermosetting resins such as phenol resin and melamine resin are used. it can. Of these, polypropylene is particularly preferably used from the viewpoints of price and moldability. As the silica sand, in order to disperse the silica sand uniformly in the resin composition and from the viewpoint of moldability, a granular sand of about 20 to 30 mesh is used. By including 20 to 50% by weight of silica sand, the specific gravity of the resin composition can be increased, and an appearance weight feeling can be obtained as a flowerpot after molding.

The type of silica sand that satisfies the above requirements is not particularly limited, but it is preferable to use coated sand for casting. Here, the coated sand for casting is silica sand mixed with about 3 to 5% by weight of a synthetic resin binder, and the synthetic resin is coated on the surface of the silica sand. Since the coated sand for castings has a uniform particle size, it is easy to mix and disperse uniformly when it is mixed with the resin, and the resin composition has good fluidity even during molding and good workability. It is preferable not only because it simply contributes to the increase in the specific gravity of the resin composition, but also from the viewpoint of the plant pot forming step. However, since the coated sand for casting is expensive, it causes an increase in the price of the flower pot. Therefore, it is preferable to use the used coated sand. Even the used coated sand has the same workability and fluidity as before use due to the uniform particle size and the absence of impurities, and after use. It is preferable because it can be obtained at a low price.

The rubber is added to prevent the impact resistance from being lowered due to the inclusion of silica sand. The type of rubber used in the present invention is not particularly limited, and natural rubber as well as synthetic rubber such as butadiene rubber and isoprene rubber can be used. The rubber is contained in the resin composition in an amount of 3 to 4% by weight. In addition, the resin composition used in the present invention may appropriately contain additives such as a coloring agent and an oxidizing agent, if necessary. In particular, the fluidity can be improved by adding an oxidizing agent.

[0012] Synthetic resin, silica sand and synthetic rubber are uniformly mixed using an appropriate mixer to prepare a pellet containing K-sand, and the pellet is molded into a suitable shape by injection molding or the like. Mold the flowerpot. Since the flowerpot thus created is made of resin containing silica sand over the entire flowerpot, it is actually heavier than the conventional synthetic resin flowerpot of the same size and shape, and is also visually pleasing. You can feel the weight.

Further, in the flower pot of the present invention, as shown in FIG. 2, a large number of holes 2, 2 ... It is possible to solve the problem of air permeability which is a drawback of the pot. If the hole has a diameter of about 0.5 to 2 mm, the soil will not flow out of the flower pot and air permeability can be imparted. Further, water can be prevented from flowing out by making the hole 2 small. The holes 2 may be arranged at random or may be aligned, but from the viewpoint of stability as a flower pot, it is preferable that the holes 2 are uniformly formed over the entire peripheral wall 1. It should be noted that even in a conventional resin flower pot, it is possible to provide air permeability by similarly forming a large number of holes in the side peripheral wall, but it is lighter than before and feels heavy in appearance. Conventional resin flower pots that do not exist are not only lighter in weight, but also look and feel lighter, and lack the stability as a flower pot. Breathability is not practical.

[0014]

[Effect of device]

 Since the flower pot of the present invention is made of a resin composition containing 20 to 30 mesh granular silica sand, it has a weighty and high-grade appearance. In addition, the flowerpot of the present invention has a weighty appearance, and is heavier than a flowerpot of the same size and the same size that is actually made of synthetic resin alone, so many small holes should be formed in the side wall. Therefore, it is possible to impart air permeability to the resin-made flower pot.
