Description

  The present invention relates to a seedling pot, and more particularly, to a seedling pot provided with a label holding portion that holds and holds a thin plate label.

  The seedlings such as flowers and vegetables are grown to a predetermined size in a seedling pot having an upper end opening integrally having a bottom part and a cylindrical part, and thereafter are directly sold in stores. In this kind of seedling pot, there may be a case where a plate-like member called a label displaying a bar code or the like on which various kinds of information are recorded in addition to a seedling variety name, a photograph, and a growing method may be attached. If such a label is attached, there is an advantage that the growth management of the seedling is simplified during the growth of the seedling, and the variety of the seedling can be accurately grasped at the time of over-the-counter sales. Thus, there is an advantage that the purchase motivation of the purchaser is increased and the labor required for the inventory management of the seller is reduced.

  In the past, the label was often inserted into the soil filled in the seedling pot, but this caused the label to collapse due to vibration during transportation, etc. There were various problems such as scratching. Therefore, there is a case where the label is fixed to the seedling pot using a stopper such as a staple, but there is a problem that a lot of labor is required for the label mounting operation. In order to solve these problems, the applicant of the present application can insert the label 30 into the upper end opening edge of the cylindrical portion 21 along the outer surface of the cylindrical portion 21 from above as shown in FIG. A seedling pot 20 provided with a slit 22 as a label holding portion that locks and holds the label 30 when inserted is proposed (see Patent Document 1). With such a seedling pot, it is not necessary to consider the above-mentioned problem that may occur when the label 30 is inserted into the soil, and the label mounting operation can be completed simply by inserting the label 30 into the slit 22.

Japanese Patent No. 3436738

  However, since the seedling pot 20 shown in FIG. 6 holds only one place in the longitudinal direction of the label 30, there is a problem that the posture of the label 30 is not stable. Further, since the label 30 is arranged along the outer wall surface of the cylindrical portion 21, the nursery pot 20 is stored in a frame-like case (also referred to as a basket tray) in which a pot storage portion is continuously provided in the vertical and horizontal directions. When the label mounting operation is performed in the state, a problem has been pointed out that the leg portion of the label 30 (portion inserted into the slit 22) is easily caught on the case, and the workability is poor.

  A main object of the present invention is to provide a seedling pot in which a label mounting operation can be easily performed and a holding power of a mounted label is high.

The seedling pot according to the present invention made to achieve the above-mentioned object is a thermoformed product of a heat-softened resin sheet, and is a seedling pot with an upper end opening integrally having a bottom part and a cylindrical part, and is a thin plate shape Provided with a label holding portion that locks and holds the leg portion of the label, the cylindrical portion is provided with at least a pair of concave wall portions that are recessed toward the inner space side and extend in the vertical direction, and the top portions of the paired concave wall portions A first slit extending in the circumferential direction of the cylindrical portion and a first slit extending in the vertical direction provided in opposing regions of the pair of concave wall portions, and having an upper end connected to one end of the first slit. The two slits constitute the label holding part , and the first and second slits are constituted by slits in which the leg parts are inserted with frictional resistance. When the leg parts are inserted into the first and second slits, Of the width direction both ends There characterized by exposed to the outside of the cylindrical portion.

  In the seedling pot according to the present invention, since the label holding part is provided in the concave wall part recessed toward the inner space side, and the first slit constituting the label holding part is provided in the top part of the concave wall part, The label can be accurately inserted into the label holding part simply by pushing the label downward along the inner wall surface of the part. In addition, since the label holding portion includes second slits that are provided in the paired concave wall portions and extend in the vertical direction, both ends of the label in the width direction are sandwiched between the second slits. As it is guided, it further proceeds gradually with only both ends in the width direction of the label exposed to the outside. Therefore, the situation where the whole leg portion of the label is exposed to the outside of the pot when the label is inserted as in the prior art is prevented. Therefore, even when the label is attached to the seedling pot stored in the frame-shaped case, the label is not caught on the frame-shaped case. Moreover, the seedling can be prevented from being damaged when the label is inserted.

  Furthermore, since the label holding part includes the second slit as described above as a constituent element, the contact part length of the label holding part with respect to the label can be increased as compared with the conventional configuration. Therefore, the label holding force increases as the contact portion length increases. Further, due to the structure of the seedling pot (label holding unit) according to the present invention, when the soil is filled in the pot, the holding power of the label is further enhanced by the soil pressure of the soil.

  A plurality of pairs of concave wall portions may be provided along the circumferential direction of the cylindrical portion as well as a pair (two strips). If a plurality of pairs are provided, a plurality of label holding portions having the above-described configuration can be provided, and label mounting work Can be further simplified. Furthermore, since the concave wall portion is recessed toward the internal space side and extends in the vertical direction, it also functions as a reinforcing rib. Accordingly, if a plurality of pairs of concave wall portions are provided, the strength of the seedling pot (tubular portion) can be improved without providing additional reinforcing ribs. Further, if a plurality of pairs of concave wall portions are provided, there is an advantage that the root winding of the seedling is improved.

  It is desirable that the seedling pot has a structure that can be stacked (stacked) in multiple stages in order to narrow the storage space and improve the transport efficiency when no seedling is planted in the internal space. Such a configuration can be obtained by gradually increasing the opening size of the cylindrical portion upward.

  The said structure WHEREIN: A concave wall part can be provided so that the lower end may open to the outer bottom face of a bottom part. If it does in this way, the intensity | strength of a cylinder part can be raised more effectively compared with the case where the lower end of a concave wall part is provided in the range of a cylinder part. In addition, when the nursery pots are stacked, the concave wall portions can be smoothly fitted to each other, so that it is possible to smoothly stack the nursery pots and to separate the nursery pots from the stacked state. . Thereby, while raising work efficiency, while being able to make bulkiness at the time of stacking compact as much as possible, the situation where the unnatural deformation which leads to workability deterioration can be prevented in each seedling pot can be prevented. .

  As described above, with the seedling pot according to the present invention, it is possible to increase the holding power of the label after mounting while simply performing the label mounting operation. As a result, it is possible to effectively prevent the label from falling over or pulling out after the label is mounted, and the work burden on the seedling farmers and retail stores is reduced.

It is a perspective view of the pot structure formed by mounting a label on the seedling pot according to the embodiment of the present invention. It is a top view of the seedling raising pot shown in FIG. It is a principal part expansion perspective view in the step before mounting | wearing a seedling pot shown in FIG. 1 with a label. It is a side view of the pot structure shown in FIG. It is a figure which shows the state which accumulated the seedling pot shown in FIG. 1 in multiple stages. It is a side view including the partial cross section of the conventional seedling pot.

  Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS. 1 is a perspective view of a pot structure in which a label 10 is attached to a seedling pot 1 according to an embodiment of the present invention, and FIG. 2 is a plan view of the seedling pot 1 shown in FIG.

  As shown in FIGS. 1 and 2, the seedling pot 1 has a bottomed cylindrical shape (cup shape) having an upper end opening integrally including a bottom portion 3 and a cylindrical portion 2 extending upward from the periphery of the bottom portion 3, In an internal space defined by the bottom portion 3 and the cylindrical portion 2, seedlings and cultivated soil (not shown) are accommodated. In the present embodiment, the bottom portion 3 has a substantially square shape with four corners formed in an arc shape, and the tube portion 2 is formed in a rectangular tube shape having an upper end opened in a substantially square shape. The seedling pot 1 is a so-called thermoformed product obtained by vacuum molding or blow molding a heat-softened resin sheet. As the resin sheet, for example, one having polypropylene (PP) as a main component and a thickness of about several hundreds μm can be used.

  As shown in FIG. 2, a through hole 4 is provided at the center of the bottom portion 3 so as to open inside and outside the pot. The radially outer side of the through hole 4 extends in the radial direction (radial direction), and is on the inner space side. A raised part 5 is provided. In the present embodiment, raised portions 5 are provided at four locations in the circumferential direction so as to surround the through hole 4. By providing the raised portion 5 in such a manner, the bottom 3 exhibits an uneven shape in the circumferential direction, and the strength of the bottom 3 is improved. The bottom part 3 is displaced upward (inside the inner space) toward the center side (see FIG. 4), and when the seedling pot 1 is placed on a flat surface, the bottom part 3 is placed between the central part of the bottom part 3 and the flat surface. A gap is formed. Thereby, the drainage function through the through-hole 4 provided in the center of the bottom part 3 is ensured, and the root rot of the seedling is prevented. In addition, when performing what is called bottom surface water supply with respect to the seedling accommodated in the said seedling pot 1, the through-hole 4 functions as a water supply port.

  The cylinder part 2 is composed of four side walls arranged such that the shape of the upper end opening is substantially square, and each side wall is inclined in the direction of gradually increasing the opening dimension of the cylinder part 2 upward. Yes. On the four side walls constituting the cylindrical portion 2, two concave wall portions 6 that are recessed toward the internal space side and extend in the vertical direction are provided in pairs. The lower end of each concave wall portion 6 is open to the outer bottom surface of the bottom portion 3.

  A first slit 7 a extending along the opening edge of the cylindrical portion 2 is provided in each of the top portions 6 a of the paired concave wall portions 6 and 6. Moreover, the 2nd slit 7b extended in an up-down direction is each provided in the area | region (surface) which opposes the concave wall parts 6 and 6 which make a pair. The upper end portion of each second slit 7b is connected to one end portion (one end portion on the center side of the side wall) of each first slit 7a. The first and second slits 7a and 7b are cuts into which legs 10b of a label 10 described later are inserted with a slight frictional resistance. The first and second slits 7a and 7b constitute a label holding unit 7 that holds and holds the label 10.

  A label 10 is inserted into the label holding portion 7 of the seedling pot 1, thereby forming a pot structure in which the label 10 is attached to the seedling pot 1 (see FIG. 1). The label 10 is a thin plate-like member formed of a relatively hard thin resin plate, and after mounting on the seedling pot 1, the label body 10a disposed above the pot, and extends downward from the label body 10a. It has integrally with the leg part 10b hold | maintained at the label holding | maintenance part 7 of the seedling pot 1. FIG. Although not shown in the figure, the label main body 10a displays a bar code or the like on which various management information is recorded in addition to the name of the seedling stored in the interior space of the seedling pot 1, a photograph, and a growing method. The leg portion 10b has a wedge shape in which the width dimension is gradually reduced downward.

  The dimensional relationship between the label holding part 7 provided in the seedling pot 1 and the leg part 10b of the label 10 held by the label holding part 7 is set as follows, for example. Referring to FIG. 3 in detail, the overall length W1 of the line segment connecting the ends of the first slits 7a, 7a that are relatively spaced apart is the width of the maximum width portion (upper end portion) of the leg portion 10b. It is set smaller than the dimension W3 (W3> W1). Further, the separation distance W2 between the second slits 7b and 7b provided in the opposing regions (surfaces) of the paired concave wall portions 6 and 6 is smaller than the width dimension W3 of the maximum width portion of the leg portion 10b. It is set (W3> W2), and the relationship of W3> W2 continues for a predetermined dimension along the longitudinal direction of the leg 10b. Moreover, the relationship of W1> W2 is materialized from the formation aspect of both slits 7a and 7b mentioned above. From the above, in this embodiment, W3> W1> W2 is set.

  The label 10 is attached to the seedling pot 1 having the above-described configuration as follows. When the leg portion 10b of the label 10 is disposed between the pair of concave wall portions 6 and 6, and the label 10 is pushed downward by a predetermined amount in this state, both end portions in the width direction of the leg portion 10b become the concave wall portions 6 and 6 respectively. Are respectively inserted into the first and second slits 7a and 7b. As the label 10 is pushed downward, the leg 10b inserted into the second slit 7b is guided downward along the second slit 7b (in a state of being sandwiched by the second slit 7b). When the pressing of the label 10 further proceeds further, the concave wall portion 6 and the leg portion 10b are elastically deformed from each other, and the upper end portion of the label leg portion 10b is the first slit due to the relationship of W3> W1. 7a and 7a are overcome, and both end portions of the label leg portion 10b are engaged with the lower surface of the top portion 6a of the concave wall portions 6 and 6 (see FIG. 4). Thereby, the mounting operation of the label 10 to the label holding part 7 of the seedling pot 1 is completed.

  As described above, in the seedling pot 1 according to the present invention, the label holding portion 7 is provided on the concave wall portion 6 that is recessed toward the inner space side, and the label holding portion 7 is provided on the top portion 6 a of the concave wall portion 6. Since the first slit 7a is provided, the leg portion 10b of the label 10 is simply moved downward along the inner wall surface of the cylindrical portion 2 of the seedling pot 1 by moving the leg portion 10b of the label 10 to the label holding portion 7 (first It can be accurately inserted into the slit 7a). Further, since the label holding portion 7 includes second slits 7b and 7b which are provided in the paired concave wall portions 6 and 6 and extend in the vertical direction, the label 10 is inserted at both ends in the width direction. The part gradually advances in a state where the part is intruded into the second slits 7b and 7b (a sandwiched state). Further, when the label 10 is inserted, only the widthwise ends of the leg portion 10b of the label 10 are exposed to the outside, and the entire leg portion 10b is not exposed to the outside. Thereby, even if it is a case where the label 10 is mounted | worn with respect to the seedling pot 1 accommodated in the frame-shaped case, the leg part 10b of the label 10 becomes difficult to catch on a frame-shaped case. Moreover, even if it is a case where the label 10 is inserted in the state where the seedling is stored in the seedling pot 1, there is no possibility that the leg portion 10b of the label 10 damages the seedling.

  Further, since the label holding portion 7 includes the second slit 7b extending in the vertical direction as a constituent element, the contact portion length of the label holding portion 7 with respect to the leg portion 10b of the label 10 can be made longer than in the conventional configuration. . Therefore, the label holding force increases as the contact portion length increases. In particular, because of the configuration of the seedling pot 1 according to the present invention, when the cultivation space is filled with the soil, the leg portion 10b of the label 10 is pressed against the inner wall surface side of the cylindrical portion 2 by the cultivation, so that the label holding power is further increased. . From the above, the seedling pot 1 according to the present invention can increase the holding power of the label 10 after mounting while performing the label mounting operation easily. As a result, it is possible to effectively prevent the label 10 from falling or the label 10 from being pulled out after the label is mounted, thereby reducing the work burden on the seedling farmers and retail stores.

  Moreover, since the recessed wall part 6 is dented in the internal space side and extends in the up-down direction, it also has a function as a reinforcing rib. In the present embodiment, a pair of concave wall portions 6, 6 are provided on the four side walls constituting the cylindrical portion 2, and each concave wall portion 6 has its lower end opened in the outer bottom surface of the bottom portion 3 in the vertical direction. Therefore, the strength of the seedling pot 1 (cylinder part 2) can be effectively increased without providing additional reinforcing ribs. In the present embodiment, since the corner ribs 8 extending in the vertical direction are provided at the four corners of the cylindrical portion 2, the strength of the cylindrical portion 2 can be further improved.

  Moreover, if a pair of concave wall parts 6 and 6 are each provided in the four side walls which comprise the cylinder part 2 like this embodiment, the advantage that the sleeping of a seedling becomes favorable is also acquired.

  Moreover, since each side wall which comprises the cylinder part 2 inclines in the direction which gradually enlarges the opening dimension of the cylinder part 2 toward upper direction, the seedling raising pot 1 which concerns on this embodiment is shown in FIG. Can be stacked (stacked) in multiple stages. Furthermore, since the concave wall part 6 provided in the side wall of the cylinder part 2 has the lower end opened to the outer bottom face of the bottom part 3, the concave wall parts 6 can be smoothly fitted and separated. Therefore, the situation where the presence of the concave wall 6 becomes an obstacle for smoothly stacking the seedling pot 1 and separating the seedling pot 1 from the stacked state, and increases the bulkiness during stacking and individual seedling pots 1. It is possible to avoid a situation in which unnatural deformation occurs.

  Note that the shape of the seedling pot 1 to which the present invention can be applied is not limited to that described above. For example, even if the bottom portion 3 has a circular shape, the cylindrical portion 2 has a cylindrical shape. However, the same applies. In addition, the material for forming the seedling pot 1 is not limited to the above, and for example, such a seedling pot 1 such as a resin sheet mainly composed of polyethylene (PE) or a resin sheet mixed with a biodegradable resin. It is also possible to select other resin sheets that are suitably used when molding the resin.

  In the above description, the first slits 7a and 7a constituting the label holding unit 7 are formed in a straight line. However, the first slit 7a can be formed in a broken line shape or an arc shape.

  Although the present invention has been described above, the present invention is not limited to the above-described embodiments, and can of course be implemented in various forms without departing from the gist of the present invention. It is. The scope of the present invention is defined by the terms of the claims, and includes the equivalent meanings recited in the claims and all modifications within the scope.
