Description

  The present invention relates to a pot storage tray that is lightweight and difficult to bend and is extremely effective for growing seedlings.

  Generally, pots made of soft synthetic resin such as polyethylene or polypropylene are widely used for raising plant seedlings such as vegetables and flower buds. Not only cultivation of seedlings, but also transportation of each pot and display and sales at stores are efficient. In order to be able to do so, it is customary to store them in a predetermined storage container.

  As such a conventional storage container, the outer frame is divided into a plurality of partition portions by vertical ribs and horizontal ribs, and the corners of the partition portions are formed by notching the corner portions where each partition portion intersects, A structure in which a support leg inclined downward from a corner is suspended and a corner of the bottom frame is connected to a lower end of the support leg to continuously connect a seedling pot storage part has been proposed (Patent Document). 1).

  Further, the outer frame is partitioned by ribs to form a plurality of openings, and support legs extend downward from a peripheral edge different from the part where the openings intersect, and a bottom is formed at the lower end of the support legs. There is disclosed a frame provided with a vent hole for ventilation at a portion where the opening intersects (Patent Document 2), and a plurality of ribs having a groove portion are used to partition the outer frame. And a bottom frame connected to the lower end of a support leg extending from below the groove instead of the corner where the openings intersect is proposed (Patent Document 3: Japanese Patent Laid-Open No. Hei. ).

In addition, since the pot storage tray is bent and the whole does not warp, it has an excellent effect that it is not inferior to conventional thick pot storage trays in terms of repeated use and handling at work. Is obtained.

  In addition, since vent holes for ventilation are formed at the corners where the compartments intersect, sufficient ventilation can be ensured even if the branches and leaves of the plant are dense, which is extremely advantageous for the growth of seedlings.

  Next, according to the pot storage tray according to the invention of claim 2, since there is a misalignment prevention projection and a plurality of them can be stably stacked without lateral misalignment, it is a matter of course to reduce the storage and transport space. It can be carried out efficiently in a short time.

  In addition, since vent holes for ventilation are formed at the corners where the compartments intersect, sufficient ventilation can be ensured even if the branches and leaves of the plant are dense, which is extremely advantageous for the growth of seedlings.

  In the pot storage tray according to the invention of claim 1, further, a continuous or discontinuous displacement prevention projection surrounding the vent is formed on the surface side of the corner portion provided with the vent. It goes without saying that both the above-described effects obtained by the invention of claim 1 and the invention of claim 2 are added.

  According to the pot storage tray of the invention of claim 3, since it is configured to detachably attach a separate displacement prevention projection member to the vent, the substantially same effect as the invention of claim 2 is obtained. Play. Of course, the pot storage tray described in, for example, Patent Document 2 described above can be used.

  According to the pot storage tray according to the invention of claim 4, in addition to the function and effect of each pot storage tray according to claims 1 to 3, the upper part of the adjacent pot storage trays can be brought into contact with each other. The storage tray can be taken out efficiently in a short time.
