Description

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

  The seedlings such as flowers and vegetables are grown to a predetermined size in a seedling pot having a bottom part and a side wall part and having an open upper end, and are then directly sold in stores. In this kind of seedling pot, there is a case where a thin plate-like member called a label displaying a bar code or the like on which various information is 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, as shown in FIG. 6, provides at least a pair of concave wall portions 102 that are recessed toward the inner space side and extend in the vertical direction on the side wall portion 101, thereby forming a pair of concave wall portions. 102, 102, the first slits 103a, 103a provided at the tops of each, and the concave wall portions 102, 102 paired with each other, provided in opposite areas (side parts) and extending in the up-down direction. A seedling pot 100 including a label holding unit 103 configured by second slits 103b and 103b connected to the first slits 103a and 103a is proposed (see Patent Document 1). As a result, the leg 110a of the label 110 is held along the second slits 103b and 103b from both sides, so that the label can be held in a stable state. Further, with such a seedling pot 100, it is not necessary to consider the above-mentioned problems that may occur when the label 110 is inserted into the cultivation soil, and the label mounting operation can be completed simply by inserting the label 110 into the label holding unit 103. Became.

Japanese Patent No. 4932894

  By the way, the seedling pot 100 in which the seedlings are grown is shipped in a state in which a plurality of seedling pots 100 are arranged in a vertical and horizontal direction in a frame-like case such as a basket tray. At this time, each seedling pot 100 is pressed by an operator or the like when arranged in the frame-shaped case or taken out, or pressed from the neighboring surrounding seedling pots 100 by an impact during transportation of the frame-shaped case. Or At that time, the side wall 101 of the seedling pot 100 may be deformed (curved) toward the internal space. When the side wall portion 101 of the seedling pot 100 is deformed to the inner space side, the paired concave wall portions 102 and 102 move away from each other, and the deformed side wall portion 101 presses the leg portion 110a of the label 110. . Therefore, there arises a problem that the holding of the leg portion 110a of the label 110 by the label holding portion 103 is released.

  The main object of the present invention is to provide a seedling pot capable of holding a mounted label with a high holding force by suppressing deformation of the side wall.

  A seedling pot according to the present invention made to achieve the above object comprises a bottom part and a side wall part extending from the outer periphery of the bottom part to an upper end opening edge, the side wall part being recessed toward the inner space side in the vertical direction, and It has at least a pair of concave wall portions extending to a position below the upper end opening edge, and a label holding portion for holding a leg portion of a thin plate-like label, and the label holding portion is a top portion of the pair of concave wall portions. A first slit extending in the circumferential direction of the side wall portion and a second slit provided in opposite sides of the paired concave wall portions extending in the vertical direction and having an upper end connected to one end of the first slit. It is a seedling pot constituted by a slit, and the upper end opening edge has a ridge extending from the side wall portion to the outer peripheral side, and the ridge has a circumferential length smaller than the circumferential length of the upper end opening edge. A first slit having a pair at both ends in the circumferential direction. Wherein the than the other end respectively positioned circumferentially outwardly.

  By configuring in this way, the collar portion that protrudes from the side wall portion to the outer peripheral side at the upper end opening edge extends outward in the circumferential direction from the region that holds the label leg portion by the label holding portion. Even if the side wall portion is pressed, the side wall portion in the area of the label holding portion can be prevented from being deformed to the inner space side of the seedling pot. Thereby, it is possible to prevent the holding of the label from coming off due to the spread of the label holding part by moving the paired concave wall parts in the direction away from each other, the pressing of the leg part of the label by the deformed side wall part, The holding power of the attached label can be increased.

  Moreover, it is preferable that a side wall part has a recessed part which is dented in the internal space side and extended in the circumferential direction above a recessed wall part, and an upper end connects with a collar part. As a result, when the operator lifts the seedling pot, the finger can be securely held without being dropped by placing the finger in the recess and hooking the finger on the tip of the buttocks. Therefore, even if it is a seedling pot in a state where a plurality of seedlings are stacked, the top seedling pot can be easily and reliably removed.

  Furthermore, it is preferable that the collar portion projects to the same position as the region of the upper end opening edge excluding the collar portion. Thereby, since the position of the outer peripheral side end is the same as the area of the upper end opening edge excluding the eaves and the eaves part, when arranging a plurality of seedling pots in a frame-like case such as a basket tray, It can prevent that the outer peripheral side edge part of a heel part is caught on the upper edge opening edge of an adjacent nursery pot, the frame part around a frame-like case, etc. Also, in the production of seedling pots, the distance between adjacent seedling pots can be reduced, and each seedling pot can be separated by simply cutting at the position of the outer peripheral side edge of the upper end opening edge after molding. Can be efficiently produced.

  In addition, it is preferable that the paired concave wall portions merge below the lower end of the leg portion of the label held by the label holding portion. Thereby, the level | step-difference part extended to an up-down direction in the side wall part of a seedling pot can be decreased, and the deformation | transformation of the side wall part by the bending of a level | step-difference part can be suppressed. Moreover, a side wall part can be reinforced with the standing wall part of the lower end of the protrusion part formed between the concave wall part which makes a pair. Therefore, the expansion of the lower region of the side wall due to the soil contained in the seedling pot can be suppressed, and the bending (deformation) of the upper region of the side wall due to the reaction of the expansion can be suppressed. Moreover, the operator can hold the seedling pot securely by placing the finger in the region where the paired concave wall portions meet and hooking the finger on the wall portion standing upright at the lower end of the protruding portion. At this time, even if it is in the state where culture soil was stored in the seedling pot, since it can hold | maintain reliably, fall of the seedling pot in operation | work etc. can be prevented. Furthermore, since the operator can reduce the force to hold the seedling pot, that is, the force toward the inner space side of the seedling pot, the deformation of the side wall portion to the inner space side of the seedling pot when holding the seedling pot is further suppressed. it can.

  As described above, according to the seedling pot according to the present invention, it is possible to provide a seedling pot in which the deformation of the side wall portion is suppressed and the holding power of the attached label is high.

It is a perspective view which shows the state which mounted | wore the seedling pot concerning 1st Embodiment of this invention with the label. It is a top view of the seedling raising pot shown in FIG. It is a principal part enlarged view in the step before mounting | wearing a label with the seedling raising pot shown in FIG. It is a side view of the seedling pot shown in FIG. It is a side view which shows the state which piled up the seedling pot shown in FIG. 1 in multiple stages. It is a perspective view which shows the conventional seedling raising pot.

  Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS. FIG. 1 is a perspective view showing a state in which the label 2 is attached to the seedling pot 1 according to one 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 a bottom 10 and a side wall 11 extending from the outer periphery of the bottom 10 to the top opening edge 11a. A seedling and a soil not shown are accommodated in an internal space formed by the bottom 10 and the side wall 11. In the present embodiment, the bottom portion 10 has a substantially square shape with four corners formed in an arc shape, and the side wall portion 11 is formed in a rectangular tube shape with an upper end opened in a substantially square shape. The upper end opening edge 11a has a substantially square shape with four corners formed in an arc shape (indicated by an arc portion R). The seedling pot 1 is a so-called thermoformed product obtained by vacuum forming or blow forming a heat-softened resin sheet. As the resin sheet, for example, a sheet mainly composed of polypropylene (PP) and having a thickness dimension of about several hundred μm can be used.

  As shown in FIG. 2, a through hole 12 is provided in the center of the bottom portion 10 so as to open to the inside and outside of the seedling pot 1. The radially outer side of the through hole 12 extends in the radial direction (radial direction). A raised portion 13 is formed on the lower side of the bottom portion. In the present embodiment, raised portions 13 are provided at three locations in the circumferential direction so as to surround the through-hole 12. By providing the raised portion 13 in such a manner, the bottom portion 10 exhibits an uneven shape in the circumferential direction, and the strength of the bottom portion 10 is improved.

  The side wall portion 11 is composed of four side walls arranged so that the shape of the upper end opening edge 11a is substantially square, and each side wall portion 11 extends in the direction of gradually increasing the opening size of the side wall portion upward. Inclined. On the upper side of the four side walls constituting the side wall part 11, a concave wall part 14 is provided in a pair so as to be recessed in the inner space side and extend in the vertical direction to a position below the upper end opening edge 11a. It has been.

  A first slit 15 a extending along the upper end opening edge 11 a of the side wall portion 11 is provided in each of the top portions 14 a of the paired concave wall portions 14, 14. In addition, second slits 15b extending in the vertical direction are provided on opposite side portions 14b of the paired concave wall portions 14 and 14, respectively. The upper end of each second slit 15b is connected to one end (one end on the center side of the side wall) of each first slit 15a. The 1st slit 15a and the 2nd slit 15b are the cut | interruptions where the leg part 2b of the label 2 mentioned later is inserted with some frictional resistance. The first slit 15a and the second slit 15b constitute a label holding unit 15 that holds and holds the label 2.

  The label 2 is inserted into the label holding portion 15 of the seedling pot 1, thereby forming a pot structure (see FIG. 1) in which the label 2 is attached to the seedling pot 1. The label 2 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 2a disposed above the pot, and extends downward from the label body 2a. It has integrally the leg part 2b hold | maintained at the label holding | maintenance part 15 of the seedling raising pot 1. As shown in FIG. Although not shown, the label main body 2a displays a bar code or the like on which various management information is recorded in addition to the variety name, photograph, and growth method of the seedling stored in the internal space in the seedling pot 1. . The leg 2b has a wedge shape in which the width is gradually reduced downward.

  The dimensional relationship between the label holding part 15 provided in the side wall part 11 of the seedling pot 1 and the leg part 2b of the label held by the label holding part 15 is set as follows, for example. Referring to FIG. 3 in detail, the overall length W1 of the line segment connecting the other ends of the first slits 15a, 15a (relatively separated ends) is the maximum width of the leg 2b of the label 2 It is set smaller than the width dimension W3 of the part (upper end part) (W3> W1). Further, the distance W2 between the second slits 15b and 15b provided in the opposing side portions 14b and 14b of the paired concave wall portions 14 and 14 is smaller than the width dimension W3 of the maximum width portion of the leg portion 2b. It is set (W3> W2), and the relationship of W3> W2 continues for a predetermined dimension along the longitudinal direction of the leg 2b. Moreover, the relationship of W1> W2 is materialized from the formation aspect of the 1st slit 15a and the 2nd slit 15b which were mentioned above. From the above, in this embodiment, W3> W1> W2 is set.

  The upper end opening edge 11a at the upper end of the side wall 11 of the seedling pot 1 is provided with a ridge 16 formed to project from the side wall 11 to the outer peripheral side. In addition, a concave portion 17 is provided above the concave wall portion 14 so as to be recessed toward the inner space side and extend in the circumferential direction, and whose upper end is connected to the flange portion 16. The heel part 16 extends so as to be parallel (horizontal) to the opening surface at the upper end of the seedling pot 1. Further, the flange portion 16 protrudes to the same position as the region (arc portion R) of the upper end opening edge 11 a excluding the flange portion 16. About 0.5 mm-1.5 mm are preferable and the dimension of the width direction (thickness direction of the side wall part 11) of the collar part 16 is preferable, and about 1 mm is more preferable. In addition, the heel part 16 may be formed so as to be inclined and extend with respect to the opening surface at the upper end of the seedling pot 1.

  The flange portion 16 has a circumferential length smaller than the circumferential length of the upper end opening edge 11a, and both ends in the circumferential direction are paired with the other ends of the first slits 15a and 15a (a relatively separated side). Are formed so as to be located on the outer side in the circumferential direction from the end of Here, in the present embodiment, as shown in FIG. 2, the circumferential length W4 of the flange portion 16 is smaller than the length W5 of the upper end opening edge 11a of the side wall portion 11. In addition, the length W5 of the upper end opening edge 11a of the side wall part 11 is the length of the line segment which connects each middle point R1 of the adjacent circular arc part R.

  The details of the dimensional relationship between the collar 16 and the label holding unit 15 are set as follows. Referring to FIG. 3 in detail, the dimension W4 of the flange portion 16 in the length direction (the circumferential direction of the upper end opening edge 11a) is the other end (relatively spaced side) of the first slits 15a and 15a. It is set to be larger than the overall length W1 of the line segment connecting the end portions) (W4> W1). The length dimension W4 of the flange 16 is set larger than the width dimension W3 of the leg 2b of the label 2 so that the curved upper end opening edge 11a does not press the leg 2b of the label 2 ( W4> W3). Therefore, in the present embodiment, the setting is such that W5> W4> W3> W1> W2.

  The concave portion 17 provided above the pair of concave wall portions 14 and 14 is formed so as to have a circular arc at the boundary with the surrounding side wall portion 11. This corresponds to a dimension in the width direction of 16. Moreover, the side wall part 11 outside the both ends of the circumferential direction of the recessed part 17 comprises the circular-arc-shaped corner | angular part 18, and is extended from the upper end to the lower end of the seedling raising pot 1. FIG. The upper end of the corner portion 18 corresponds to the arc portion R described above, and a corner rib 19 is provided at the center in the circumferential direction of the corner portion 18 so as to protrude toward the inner space of the seedling pot 1 and extend in the vertical direction.

  Here, the paired concave wall portions 14 and 14 formed on the side wall portion 11 join below the lower end of the leg portion 2b of the label 2 held by the label holding portion 15 (see FIG. 1). (Indicated by the junction 20). The upper end of the protruding portion 21 extends so as to be connected to the concave portion 17 (see FIG. 4), and the lower end 21 a of the protruding portion 21 forms a wall portion that rises from the joining portion 20 toward the protruding portion 21.

  The outline | summary of the operation | work until it grows and ships a seedling using the seedling pot 1 which consists of the above structure is demonstrated. First, when growing seedlings in the seedling pot 1, for example, an operator takes out one seedling from the seedling pots 1 stacked as shown in FIG. 5 and stores them side by side in a frame-like case such as a basket tray. At this time, when taking out the seedling pot 1 positioned at the top of the stacked seedling pots 1, the operator can easily place the finger in the recess 17 and hook the finger on the outer peripheral end of the heel part 16. The seedling pot 1 can be taken out.

  Subsequently, in the internal space of each seedling pot 1 arranged in a frame-shaped case, the cultivated soil is accommodated, and seedlings to be grown, seedlings that have been separately germinated and grown, and the like are planted. At this time, since the side wall portion 11 of the seedling pot 1 forms a flat joining portion 20 because the paired concave wall portions 14 and 14 join together below, The deformation (bulging) of the side wall portion 11 due to the bending of the stepped portion of the portion 14 can be suppressed. Moreover, the side wall part 11 can be reinforced with the standing wall part of the lower end 21a of the protrusion part 21 formed between the concave wall parts 14 and 14 which make a pair.

  When the seedling grows in the seedling pot 1, the label 2 is attached to each seedling pot 1 as preparation for shipment. The label 2 is attached to the seedling pot 1 as follows. When the leg portion 2b of the label 2 is disposed between the pair of concave wall portions 14 and 14, and the label 2 is pushed downward by a predetermined amount in this state, both end portions in the width direction of the leg portion 2b become the concave wall portion 14, 14 is respectively inserted into the first slit 15a and the second slit 15b. As the label 2 is pushed downward, the leg 2b inserted into the second slit 15b is guided downward along the second slit 15b (while being sandwiched between the second slits 15b). When the downward pressing of the label 2 further proceeds, the concave wall portion 14 and the leg portion 2b are elastically deformed from each other from the relationship of W3> W1, and the upper end portion of the leg portion 2b becomes the first slit 15a. 15a, both ends in the width direction of the leg portion 2b are locked to the lower surface of the top portion 14a of the concave wall portions 14 and 14 (see FIG. 4). Thereby, the mounting operation of the label 2 to the label holding part 15 of the seedling pot 1 is completed.

  When the label 2 is attached to each seedling pot 1, the seedling pot 1 is transferred to a shipping frame-like case as necessary. In this case, the seedling pot 1 is heavy because the culture soil is accommodated and the seedlings are growing, but the operator places a finger on the junction 20 of the side wall 11 of the seedling pot that has been taken out. By hooking a finger on the lower end 21a of the protrusion 21, the seedling pot 1 can be reliably held without dropping. At this time, the force for holding the seedling pot 1 can be reduced, and the side wall 11 can be further suppressed from being deformed to the inner space side of the seedling pot 1.

  In this way, the seedling pots 1 arranged in the frame-like case are shipped and arranged and sold at the store. Here, when the nursery pot 1 is transported at the time of shipment, even if a pressing force is applied from the surrounding nursery pot 1 or the frame portion of the frame-like case due to vibration or impact, the upper edge of the side wall 11 is opened. Deformation of the side wall portion 11 in the region of the label holding portion 15 can be suppressed by the flange portion 16 formed in 11a. At this time, the pressing force received by the seedling pot 1 can be absorbed by the deformation of the corner portion 18 which is a region where the heel portion 16 is not formed. Moreover, since the confluence | merging part 20 is formed in the side wall part 11 below the concave wall parts 14 and 14 which make a pair, expansion (deformation) of the lower part of the seedling pot 1 can be suppressed, and by reaction of expansion The curvature of the upper region of the side wall portion 11 can be prevented, and the appearance of the seedling pot 1 can be maintained well.

  As explained above, the seedling pot 1 according to the present invention has the first slit 15a and the second slit 15b of the label holding part 15, so that the label 2 is simply pushed forward. The two leg portions 2b can be accurately inserted into the label holding portion 15, and both end portions in the width direction of the leg portions 2b of the label 2 can be sandwiched and guided. As a result, the length of the contact area between the label 2 and the label holding portion 15 can be increased to increase the holding force. Moreover, the deformation | transformation in the area | region of the side wall part 11 of the seedling raising pot 1, especially the label holding | maintenance part 15 can be suppressed by the collar part 16 formed in the upper end opening edge 11a. As a result, the holding of the label 2 is released due to the expansion of the label holding part 15 due to the deformation of the side wall part 11 toward the inner space side of the seedling pot 1, the pressing of the leg part 2b of the label 2 by the deformed side wall part 11 or the like. Can be prevented, and the holding power of the attached label 2 can be increased.

  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 10 has a circular shape, the side wall portion 11 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 15a and 15a constituting the label holding unit 15 are formed in a straight line. However, the first slit 15a can be formed in a broken line shape or an arc shape.

  Further, in the seedling pot 1, a second heel part narrower than the heel part 16 may be formed at the upper end opening edge 11 a (arc part R) excluding the heel part 16. Thereby, the deformation | transformation of the whole seedling pot 1 can be suppressed, and a shape can be stabilized.

  In addition, although the label holding part 15 and the collar part 16 showed the example formed in the upper part side of the four side walls of the side wall part 11, it does not restrict to this. When the square tube-shaped seedling pot 1 is used, the label holding part 15 and the heel part 16 may be formed on at least one side. For example, when forming on two sides, it may be formed on each of the opposing sides or on each of the adjacent sides. In any case, both ends in the circumferential direction of the flange portion 16 are positioned on the outer side in the circumferential direction from the other ends (end portions on the relatively separated side) of the first slits 15a and 15a of the label holding portion 15. By forming the flange portion 16, deformation of the side wall portion 11 can be suppressed, and the label 2 can be reliably held by the label holding portion 15.

    While the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the present invention. 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.
