Description

  The present invention relates to a thin flexible resin seedling pot used for growing seedlings of plants such as vegetables and flowers.

  Conventionally, seedling pots made of soft synthetic resins such as polyethylene and polypropylene have been used to grow seedlings such as flowers and vegetables. The seedlings to be raised in this seedling pot are transported for each seedling pot and displayed and sold at the store. At the time of display and sale at a store, a display board on which information on seedlings such as the name of the seedling and the cultivation method is displayed is attached to the seedling pot for the consumer. The display board attached to the seedling pot is composed of a display part for displaying information about the seedlings and a leg part extending from the display part, and in many cases, the leg part of the display board is used for the cultivation soil stored in the seedling pot. It is plugged in directly.

  However, in the method of directly inserting the display board into the cultivation soil, the display board can be easily pulled out from the seedling pot. For example, the display board is pulled out due to impact during transportation or mischief of consumers. In particular, when the seedling is a young seedling, there is a problem that the display board cannot be correctly returned to the original seedling pot.

  Therefore, in order to solve the above-mentioned problems, Patent Literature 1 discloses a seedling pot provided with a heel part provided at the upper edge of the seedling pot and a hole for inserting a display plate into the heel part. Has been. According to this seedling pot, the display board is inserted into the hole provided in the buttock and attached to the seedling pot in a state of being engaged with the hole. Therefore, it is possible to make it difficult to pull out the display board from the seedling pot and to simplify the operation of attaching the display board.

Further, in Patent Document 2, the present inventors can insert and remove a hard thin plate-like display board from the upper side along the outer surface of the side wall portion into the upper end opening edge of the seedling pot, and this display board is inserted by a predetermined length. When it is inserted, it has been proposed to form a slit that is locked and held on the display board.
No. 7-46128 JP 2002-045046 A

  However, in the method described in Patent Document 1 described above, since the display board is supported only by the hole portion, the display board is likely to wobble and is attached to a certain seedling pot due to the influence of wind, impact during transportation, own weight, etc. There is a problem that the display board cannot be fixed in an almost upright state with respect to the seedling pot, for example, the display board is tilted to the right or the display board attached to another seedling pot is turned forward. .

  Further, in the method described in Patent Document 2, even if the lower end of the label is in contact with the outer surface of the side wall portion in a state where the seedling pot is stationary, the lower end of the display plate is moved to the side wall portion only by slightly shaking the seedling pot. In some cases, the upper part of the display board falls apart from the outer surface of the display. Such a seedling pot is, for example, slightly shaken when taken out from the frame-like case, and the lower end of the display board is separated from the outer surface of the side wall. When trying to return the seedling pot to the frame-shaped case in this state, the lower end of the display plate interferes with the partition of the frame-shaped case and other seedling pots (including seedlings and soil) accommodated in the frame-shaped case. At the time of over-the-counter sales, in order to determine the seedlings contained in the seedling pot, it is assumed that the seedling pot is taken out from the frame-shaped case, and the seedlings are observed at hand and then returned to the frame-shaped case. At this time, there is a concern that the seedling pot may not be stored in the frame-like case without knowing that the lower end of the display plate is separated from the outer surface of the side wall of the seedling pot, or that seedlings planted in other seedling pots may be damaged. Is done.

The inventors of the present invention have arrived at the present invention as a result of intensive studies to solve the above-mentioned problems. That is, claim 1 of the present invention is a flexible resin-made seedling pot having a bottomed upper end opening having a bottom part and a side wall part, which is a part of the side wall, and is predetermined between the upper edge part of the side wall. A plurality of concave wall portions that are recessed toward the inner space side with respect to the outer surface of the other side wall in the spaced portion, and upper ends that face the opening surfaces of the respective concave wall portions, are stored in the inner space. It has a slit to insert a display on which information related to the seedling stored in the seedling pot is displayed, and the lower part of the display plate inserted into the slit is separated from the outer surface of the side wall on the lower surface side of the upper end of the concave wall. It is the seedling pot characterized by providing the tongue piece which regulates.

According to the seedling pot according to claim 1, a pressing force sufficient to restrict the lower end of the display plate in which the information plate-related information display is inserted into the slit from the outer surface of the side wall portion. A tongue piece is provided for the display board. The tongue piece is disposed outside the display plate inserted into the slit on the lower surface side of the upper end of the concave wall, and presses the display plate from the outside toward the inside. Even if an external force is applied to the lower part of the display plate so as to be separated from the outer surface of the side wall portion of the seedling pot, the lower portion of the display plate automatically comes into contact with the outer surface of the side wall portion by the biasing force of the tongue piece when released from the pressure. Since the concave portion in which the slit is opened is a part of the side wall and is a portion depressed toward the storage space side from the outer surface of the other side wall, by using the concave wall portion as a mark, the position of the slit is It is grasped from the side wall side of the seedling pot. Moreover, although the thing until now was easy to fall down if soil was not put, since the thing of this invention is equipped with the slit in the upper part, even if it puts in a little soil, it is hard to fall down even if it does not put soil.

In the seedling pot according to claim 3, in the seedling pot described above, the slits have both ends thereof extended toward the outer edge of the upper end portion of the concave wall at a desired angle with respect to the inner edge of the upper end portion of the concave wall. A tongue line is formed by forming a polygonal line shape and pushing a portion surrounded by the slit downward.

The seedling pot according to claim 4 is the seedling pot according to claim 3, wherein the center portion of the slit is formed along the inner edge of the upper end portion of the concave wall.

The seedling pot according to claim 5 is the seedling pot according to claim 3, wherein both ends of the slit are inclined at an angle with respect to the inner edge of the upper end of the concave wall. The angle is preferably 50 to 60 degrees.

The seedling pot according to claim 6 is the seedling pot according to claims 1 to 5,
A rib for increasing the pressing force of the tongue piece against the display plate is provided at the base end portion of the tongue piece and / or in the vicinity thereof.

The seedling pot according to claim 7 is the seedling pot according to claims 1 to 6, wherein the relationship between the display plate and the slit is such that the total length of the slit is shorter than the outer width of the display plate, and the length of the central portion of the slit. Is shorter than the inner width of the wedge portion of the display board, the length between both ends of the slit is longer than the inner width of the wedge portion, and the length between both ends of the slit is equal to the upper end width of the display plate or It is a nursery pot that is short.

In the present invention, even if the lower part of the display board inserted into the slit is separated from the outer surface of the side wall part, the lower part of the display board is separated from the outer surface of the side wall part because it automatically contacts the side wall part by the biasing force of the tongue. Interference with other objects such as seedlings planted in a frame-like case or other seedling pots can be prevented. In addition, since the upper end of the recessed wall where the slit is opened is provided at a portion spaced a predetermined distance from the upper edge of the side wall, the portion at the predetermined distance is inserted into the slit. Since the display board has a guide, it is easy to insert and the display board is sandwiched between the inner surface of the side wall and the cultivated soil, so that the display board can be fixed in a substantially upright state with respect to the seedling pot.
Moreover, since a plurality of concave wall portions are provided, the stability of the seedling pot that does not contain soil can be improved.
The seedling pot with the concave wall upper end recessed in a V-shape in the direction perpendicular to the length direction and the slit positioned at the bottom of the recess is also suitable for inserting the display board with the soil filled. There is an effect that the display plate can be easily put into the slit.

Hereinafter, an embodiment of a seedling pot according to the present invention will be described with reference to the accompanying drawings. Note that the same or corresponding parts are denoted by the same reference symbols throughout the drawings.

1A is a plan view showing an embodiment of a seedling pot according to the present invention, FIG. 1B is a longitudinal sectional view taken along line AA in FIG. 1A, and FIG. (B) It is a B section enlarged view of a figure. The seedling pot 1 is a space surrounded by a bottom 2, a side wall 3 standing upward from an edge of the bottom 2, and the side wall 3 and the bottom wall 2, and stores seedlings and culture soil. A space and an opening surface formed by the upper edge portion 5 of the side wall 3 are provided for putting seedlings and culture soil into the storage space. The seedling pot 1 is a flexible resin container having a bottomed top end opening having a substantially square bottom part 2 having four corners formed in a curved shape and a top end opening surface opened in a similar shape slightly larger than that, A concave wall portion that is recessed toward the inner space side from the outer surface of the other side wall is provided in each of the square side walls at a portion 6 spaced from the upper edge portion 5 of the side wall portion 3 by a predetermined distance. A slit into which a display board on which information on seedlings stored in a seedling pot stored in the internal space is displayed is inserted into the upper part (hereinafter referred to as the concave wall upper end part 4) facing the opening surface of the concave wall part. 4a is provided. The seedling pot 1 is made of a soft synthetic resin such as polyethylene PE or polypropylene PP, and is obtained by vacuum molding or blow molding a thin resin material having a thickness of about 0.4 mm mixed with a predetermined amount of polyethylene (PE), for example.

  The side wall 3 has a shape that gradually increases in diameter from the lower side wall 2 a at the peripheral edge of the bottom 2. The side wall 3 has a plurality of concave wall portions 3 a that are recessed toward the storage space from the outer surface of the other side wall 3 and extend in a band shape from a position having a predetermined distance 6 between the side wall 3 and the upper edge portion 5 of the side wall 3. Is formed. Further, the side wall 3 is provided with a plurality of ribs 3b extending in the vertical direction at a predetermined interval in the circumferential direction over the entire surface including the vicinity of the concave wall 3a.

The concave wall upper end portion 4 is formed in a substantially trapezoidal shape that closes the upper end portion of the concave wall portion 3a. The outside of the concave wall upper end 4 constitutes a trapezoidal lower base. The concave wall upper end 4 is supported by the upper end of the concave wall portion 3a on the inner end edge constituting the trapezoidal upper base and the oblique sides on both sides thereof, thereby forming the side wall portion 3 (concave wall portion 3a). ) Is regulated to a desired angle, and is maintained in a substantially horizontal direction. That is, in this embodiment, the concave wall portion 3 a becomes a reinforcing structure that regulates the inclination angle of the concave wall upper end portion 4 with respect to the side wall portion 3.

The concave wall upper end 4 includes a slit 4a cut into a fold line, a tongue piece 4b formed by being surrounded on three sides by the slit 4a, a pair of concave portions 4c provided near both ends of the slit 4a, A slope 4d provided at the center of the tongue piece 4b and inclined downward from the vicinity of the outer edge of the upper end 4 of the concave wall inward.
The slit 4 a is formed in a linear shape along the inner edge of the upper end 4 of the concave wall, and the slit 4 a is linear with a desired angle θ with respect to the inner edge of the upper end 4 of the concave wall. It is formed toward the outer edge of the part 4. The angle θ of the slit 4a is most preferably set within a range of 50 ° to 60 °.

  The tongue piece 4b is formed in the shape of a tongue on the radially inner side of the seedling pot 1 by forming the slit 4a as described above. As shown in FIGS. 2 to 4, when the display plate 10 is inserted into the slit 4 a, the tongue piece 4 b is pushed into the lower surface side of the concave wall upper end portion 4. The tongue piece 4b pushed into the lower surface side of the upper end portion 4 of the concave wall presses the display board 10 against the outer surface of the concave wall portion 3a by the elastic force to return to the original position, and leaves the concave wall portion 3a. regulate. In addition, it is preferable to provide a V-shaped fold at the end of the tongue piece 4b, because repulsion occurs when the display plate label is inserted, and the nursery pot becomes more difficult to fall.

Both the concave portion 4 c and the slope 4 d function as ribs that increase the pressing force of the tongue piece 4 b against the display plate 10.
The concave portion 4c has a shape in which the upper surface side of the concave wall upper end portion 4 is recessed concavely and protruded toward the temporary surface side, and is provided so as to face both end portions of the slit 4a. More specifically, the slit 4a is provided from the vicinity of the outer edge of the upper end portion 4 of the concave wall to the vicinity of the oblique side so as to cross the extended line at both ends of the slit 4a. When the concave portion 4c is provided in this way, when the tongue piece 4b is pushed to the lower surface side of the concave wall upper end portion 4 as shown in FIGS. 2 to 4, both end portions of the concave wall upper end portion 4 (of the tongue piece 4b). Deflection of the part located on both sides) is suppressed. The concave portion 4c effectively suppresses the bending of both end portions of the upper end portion 4 of the concave wall, thereby efficiently generating elasticity at the base end portion of the tongue piece 4b and increasing the pressing force of the tongue piece 4b against the display board 10.

In this embodiment, by arranging the outer edge of the slope 4d between the inner ends of the pair of recesses 4c so as to be continuous with the inner ends of the pair of recesses 4c, the recess 4c and the slope 4d The synergistic action is drawn out so that the pressing force of the tongue 4b against the display board 10 is further increased.
Alternatively, the angle of the slope 4d may be increased to lower the position of the slit 4a from the level of the outer end and inner end of the concave wall upper end 4. That is, it is preferable that the concave wall upper end portion 4 is recessed in a V shape in a direction perpendicular to the length direction, and the slit is positioned at the bottom of the recess. By adopting such a configuration of the concave upper end portion 4, even when the display board is inserted into the seedling pot containing the culture soil, the slit entrance is V-shaped when the display board is inserted. The plate can easily enter the slit 4a.

The slope 4d functions as a rib that increases the rigidity of the lower piece 4b. Specifically, an elastic force for pressing the display plate 10 is generated at the base end portion of the tongue piece 4b, while a reaction force of the display plate 10 acts on the distal end portion of the tongue piece 4b in a direction almost opposite to the elastic force. By providing a step over the entire length direction of the tongue piece 4b by the slope 4d, the rigidity of the tongue piece 4b with respect to the elastic force and the reaction force of the display plate is enhanced. Thereby, the elastic force generated at the base end portion of the tongue piece 4b and the vicinity thereof is transmitted to the tip end of the tongue piece 4b with almost no attenuation.
Further, the slope 4d, like the tongue piece 4b, is gradually narrowed toward the inside in the radial direction of the seedling pot 1, and the width of the leading edge of the slope 4d is made narrower than the central part of the slit 4a, thereby displaying It also functions as a guide for guiding the lower end of the plate 10 to the center of the slit 4a.

  FIG. 5 is a front view showing an example of the display board 10 inserted into the slit 4a. The display board 10 is a hard thin plate made of plastic or the like, and relates to the seedlings contained in the seedling pot 1 on the display board upper part 12 that protrudes upward from the slit 4a by inserting the V-shaped display board lower part 11 into the slit 4a. Information is specified. An intermediate portion 13 between the display plate lower portion 11 and the display plate upper portion 12 is a portion held by the slit 4a and is formed in a tapered shape. The lower surface of the display panel middle part 13 is narrower than the upper end of the display panel lower part 11. As a result, a wedge portion 14 is formed at the upper end of the lower portion 11 of the display plate to be engaged with the edge of the slit 4 a from the lower surface side of the upper end portion 4 of the concave wall.

The dimensions of the slit 4a will be described in relation to the display board 10. When the outer width of the wedge portion 14 and _{W 1,} as shown in FIG. 3, the overall length of the slit 4a _(L 1 + 2L ₂₎ is slightly shorter than the W1. When the inner width of the wedge portion 14 and W _2, the length L ₁ of the central portion of the slit 4a _(the width of the end portion of Shitahen 4b) is slightly shorter than the W _2, between the two ends mutually slit 4a the length L _{3 (the} width of the base end portion of Shitahen 4b) is longer than W _2. Note that the length L ₃ between both ends of the slit 4 a is shorter than the upper end width W ₃ of the display panel 13.

Since the outer width W1 of the wedge portion 14 is longer than the entire length of the slit 4a, the display plate 10 has the side edge of the lower portion of the display plate 11 side of the slit 4a before the wedge portion 14 is inserted into the slit 4a. Abut against the edge. For this reason, as shown in FIG. 3, the display board 10 is deformed into a curved shape in which both sides in the width direction are along the both ends of the slit 4a and the vicinity of the center line protrudes slightly inward in the radial direction of the seedling pot 1. At the same time, the concave portion 3a is inserted inward and / or the base end portion of the tongue piece 4b is bent outward and the wedge portion 14 is inserted. When the wedge part 14 gets over the slit 4a, the bending of the display panel 10 is slightly eliminated, and the wedge part 14 can be locked to the edge of the slit 4a from the lower surface side of the concave wall upper end part 4. Since the width of the panel intermediate portion 13 is wider than the length L ₁ of the central portion of the slit 4a, the display panel 10, deflection is held in the slit 4a in a state of being slightly curved be solved somewhat.

In the seedling pot 1, the display board 10 inserted into the slit 4 a is pressed against the outer surface of the concave wall portion 3 a by the tongue piece 4 b. Since the center portion of the slit 4a is formed along the inner edge of the upper end portion 4 of the concave wall, the lower portion 11 of the display plate can be pressed along the outer surface of the concave portion 3a and the small size of the upper end portion 4 of the concave wall can be reduced. The tongue piece 4b having a desired size can be formed while achieving the desired size. When the tongue piece 4 b is pushed into the lower surface side of the concave wall upper end portion 4, both side edges of the tongue piece 4 b come into strong contact with both end portions of the display plate 10 slightly bent outward from the concave wall upper end portion 4. Since the display panel 10 is bent slightly toward the outside of the concave wall upper end 4, the display panel 10 is pressed against the outer surface of the recess 3 a without being bent at the pressing portion even when pressed by the tongue piece 4 b. In addition, since the tongue piece 4b reinforces both side edge portions that serve as a pressing portion of the display board 10 by the slope 4d, the elastic force enhanced by the cooperative action of the recess 4c and the slope 4d is efficiently applied to the display board 10. Can be loaded.

On the other hand, the angle θ of the slit 4a can be set as appropriate within a range of 0 ° <θ ≦ 90 °. However, the closer the angle θ is to 90 °, the larger the curvature of the display plate 10 when the slit 4a is inserted. Therefore, it becomes difficult to insert the display board 10 into the slit 4a. Moreover, after inserting in the slit 4a, the appearance of the display board 10 falls and it becomes difficult to see the information regarding the seedlings specified on the display board 10. Conversely, the closer the angle θ is to 0 °, the smaller the curvature of the display board 10 inserted into the slit 4a and the shorter the tongue piece 4b, so that the pressing force of the tongue piece 4b against the display board 10 is reduced. Becomes difficult to act. From such a viewpoint, the angle θ of the slit 4a is most preferably set within a range of 50 ° to 60 °.

Furthermore, in the said embodiment, although the bottom part 2 is substantially square-shaped and the upper-end opening part is mentioned and demonstrated the raising seed pot 1 as an example, the bottom part 2 is shapes other than this, for example, substantially circular shape, for example. The present invention can be applied to a seedling pot having various shapes such as a seedling pot or a seedling pot having a substantially circular upper end opening.
Further, an opening may be provided in the bottom 2 in order to discharge water to the outside or to guide the roots of the seedlings extending toward the bottom 2 along the concave wall.
