Description

The present invention relates to an assembly container suitable as a plant cultivation tank, an aquarium, or the like.

Conventionally, equipment for hydroponically cultivating vegetables such as lettuce has been proposed in a plant factory. For example, an LED (Light Emitting Diode) lighting device is installed in a closed space such as a building, and while artificially controlling the cultivation environment such as temperature, humidity, and lighting conditions, an environment suitable for growing plants is constructed and quality is achieved. Facilities for growing good vegetables are provided.

As an example of this type of plant cultivation system, a lettuce cultivation system equipped with a cultivation tank, a water supply tank, a fertilizer tank, a CO ₂ tank, a light source, an air conditioner, a fan, a CO ₂ sensor, and various sensors is known (Patent Document). 1).

In the lettuce cultivation system described in Patent Document 1, a water tank made of a resin molded body is applied as a cultivation tank. However, when the size of the cultivation tank used in the plant factory is large, it becomes difficult to transport and install the cultivation tank. In addition, plant factories differ in production scale, installation environment, etc., and the size of cultivation tanks also varies. Therefore, it is necessary to prepare cultivation tanks of different sizes according to the scale of the plant factory.

Therefore, a plant cultivation tank that can be divided into a plurality of units and whose size can be freely adjusted has been studied (see Patent Document 2). The size of the plant cultivation tank described in Patent Document 2 can be freely adjusted by providing one or a plurality of connecting units between the two end units.

However, when a connection unit is provided, the distribution of the supplied water, nutrient solution, etc. tends to be delayed in this part, and the water, nutrient solution, etc. can be evenly distributed to the entire plant in the cultivation tank. There is a problem that it is difficult. In addition, there is a problem that the supplied water, nutrient solution, etc. leak from the connecting unit portion. In order to avoid these problems, generally, the inner surface of the cultivation tank is covered with a waterproof sheet (see Patent Document 3).

By providing a margin in the separation distance D, for example, the inner member 100B that is bent and supported by the protrusion member 101C can be fixed by a fixing member 105 such as a clip as shown in FIG. 4B.

In a cross-sectional view of the outer member 100A (main body member 101) in the thickness direction, it is preferable that the tip (top) of the protrusion 101C is rounded. As a result, the inner member 100B attached to the protrusion 101C reduces the pressure received from the tip of the protrusion 101C, and has the effect of preventing the inner member 100B from being damaged.

By installing a support member M such as Styrofoam so as to bridge from the region R1 inside the protrusion 101C on one side 1β to the region R2 inside the protrusion 102C on one side 2β, plants and the like to be cultivated there can be grown. Can be placed. At this time, the protrusions 101C and 102C play a role of controlling the displacement of the installed support member M.

One surface 1γ and 2γ located on the outer side of the three surfaces support the ends of the one surface 1β and 2β located between them, respectively, so that the main body is subjected to an outward load when the bent portions 101B and 102B are loaded. Deformation of the members 101 and 102 can be suppressed.

The length L of the protruding portion 101C in the protruding direction is preferably 10 mm or more and 50 mm or less, and more preferably 20 mm or more and 40 mm or less. If the length L is less than 10 mm, when the inner member 100B is attached, the folded-back portion of the inner member 100B becomes short and cannot be sufficiently fixed to the protrusion 101C. Further, in this case, the support member M cannot be installed. Further, if the length L exceeds 50 mm, the distance from the assembly container directly above the assembly container becomes narrow when the assembly containers are stacked and installed.
