Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a thin and flexible resin-made seedling raising pot used for growing seedlings of plants such as vegetables and flowers.

[0002]

2. Description of the Related Art The seedling raising pot is a thin, flexible cup-shaped container which is mass-produced by blow molding from a resin material such as polypropylene or polyethylene. The seedling raising pot alone is flexible and easily deformed. Therefore, normally, the seedling raising pots are stored in the respective recesses of a rigid frame-shaped case having a plurality of recesses for individually accommodating the seedling raising pots, and soil or fertilizer is put in each seedling raising pot so that seedlings can grow. I have to. In addition, a plurality of seedling raising pots housed in a frame-shaped case are stored and transported together with the frame-shaped case so that seeds and seedlings grown in each seedling raising pot can be sold over the counter.

A plurality of seedling raising pots are integrally blow-molded in a vertical and horizontal arrangement, and are individually separated as necessary. The shapes of the blow-molded seedling raising pots are
A cup shape of a bottomed upper end opening having a circular bottom part and a side wall part of a cylindrical shape or a substantially rectangular tube extending from the peripheral edge of the bottom part is common, and the upper end opening edges of the side wall parts of the adjacent seedling pots are adjacent to each other. It is connected by hand for easy separation by hand. In the state of a composite seedling raising pot in which a plurality of seedling raising pots are integrally connected, a plurality of seedling raising pots are stored in respective recesses of the frame-like case, or a plurality of seedling raising pots individually separated from the composite seedling raising pot Stored in a frame-shaped case, it is used for seedling growth and over-the-counter sales.

[0004]

By the way, in order to clearly indicate the type of seedlings grown in the soil housed in the seedling raising pot, in general, the name and characteristics of seedlings, growing method, flowers when grown, etc. A thin hard resin plate label with pictures and photographs is inserted into the soil in the nursery pot. In some cases, a bar code that records the price of seeds and seedlings is clearly indicated on the label. Such labels make it convenient for the growers of seeds to manage the growth of seeds. Further, the label is necessary in order to prevent buyers of seeds and seeds from making mistakes in the types of seeds and seeds in the case of over-the-counter sales, and increases the purchaser's willingness to purchase. In addition, the bar code label facilitates price control of seeds sold at stores.

However, the soil of the nursery pot is soft, and the label inserted into this soil may be collapsed by external force such as wind, or it may be easily pulled out from the soil and left as it is by a buyer who wants to see the label well. Therefore, it was troublesome for over-the-counter sellers to manage the presence or absence of labels on seedling pots. In addition, the label is inserted between the inner surface of the side wall of the nursery pot and the soil so that the label does not damage the seedlings in the soil, but the label is inserted in the soil at any position. The seedlings may be damaged by.

[0006] From the above, some labels have been made to make it difficult to pull out from the soil by forming irregularities that bite into the soil in the label to be inserted into the soil of the nursery pot. However, even if the label is uneven, the soil of the seedling pot itself is soft, so there is almost no effect of preventing the label from being pulled out. It is also possible to attach a clip with a label with a clip to the opening edge of the thin flexible seedling pot so that the label does not easily come off in the seedling pot so that the label does not damage seedlings in the soil. It is done in the department. However, a label with a clip is expensive, and the work of attaching the label to the nursery pot with the clip is troublesome, which is not practical.

An object of the present invention is to provide a nursery pot of a flexible resin container, in which a label is easily attached without damaging seedlings in soil and is not easily removed, and which is particularly suitable for over-the-counter sales. To do.

[0008]

In order to achieve the above object, the present invention provides a flexible resin seedling pot having an upper end opening having a bottom portion and a cylindrical side wall portion. A hard thin plate-like label can be inserted and removed along the line, and when this label is inserted for a specified length, a slit is formed that holds the label and holds it, and the peripheral portion of the slit.
, Insert the bottom of the label inserted from above into the slit.
Form a guide groove to slide and guide, and
It is characterized in that a slit is formed in .

Here, the number of slits formed in the upper opening edge of one seedling raising pot is either singular or plural, and one label is inserted into each slit. Since this label is inserted from the slit along the outer surface of the side wall of the nursery pot, it does not touch the soil in the nursery pot and does not damage the seedlings in the soil. Since the label is locked in the slit, it will not come off easily from the seedling raising pot. The label can be applied to existing products with unevenness that will get caught in the soil when it is inserted into the soil in the nursery pot, or existing products without the above unevenness, and the label of these existing products will be hooked specifically in the slit of the nursery pot. A dedicated product with such notches and protrusions and depressions is applied.

In the present invention, the cylindrical side wall portion is partially formed with a concave wall portion concaved toward the inner surface of the side wall portion and the upper end opening of the concave wall portion to form a part of the upper end opening edge of the side wall portion. It is possible to integrally form the top edge portion and form a slit in the top edge portion, or to integrally form an outwardly extending flange portion at the upper end opening edge of the tubular side wall portion, and the flange portion is formed. It is practically desirable to form a slit in the.

In order to facilitate the insertion of the label into the slit, it is effective to form a guide groove in the peripheral portion of the slit for guiding the lower end of the label inserted from above by sliding it toward the slit. .

The shape of the slit in the length direction may be a straight line shape or a curved line shape including a broken line, and such a slit shape is selected corresponding to the label shape.

Further, in the present invention, a plurality of flexible resin-made seedling pots having a bottom portion and a cylindrical side wall portion and having an upper end opening are aligned in the vertical and horizontal directions to partially integrate the upper end opening edges of adjacent seedling raising pots. In the combined seedling raising pot connected to, when the lower part of the hard thin plate-like label is inserted from the upper side along the outer surface of the side wall portion into the upper end opening edge of at least one of the plurality of seedling raising pots, the label withdrawing direction to this label It is characterized in that a slit for retaining the label is formed by being locked with respect to.

This composite seedling raising pot is suitable for growing seedlings and selling them over the counter in a state where a plurality of seedling raising pots are integrated. In this composite seedling raising pot, slits may be formed in all of a plurality of consecutive seedling raising pots, and the number, directionality, size, etc. of the slits formed in each of the plurality of seedling raising pots are not limited. .

The present invention also provides a composite seedling raising pot in which a plurality of flexible resin-made seedling raising pots having an upper end opening having a bottom portion and a cylindrical side wall portion are aligned and the upper end opening edges of adjacent seedling raising pots are integrally connected. From the upper side between the side wall parts of the seedling raising pots, which are connected by the opening edge extension portions, which are surrounded by the upper end opening edges of the three or more seedling raising pots and integrally connect the upper end opening edges to each other. It is characterized in that a hard thin plate-like label can be inserted and removed, and a slit is formed to hold and hold the label when the label is inserted by a predetermined length.

In this case, the combined seedling raising pot is also sold over the counter in a combined state in which three or more seedling raising pots are connected in series, and a label common to these three or more seedling raising pots is inserted into the slit of the opening edge extension. This eliminates the need to insert a label into each of the seedling raising pots. In the case where the combined seedling raising pot has opening edge extension portions at a plurality of locations and is used for over-the-counter sales, slits may be formed in at least one opening edge extension portion.

Combined nursery pot 1Wa described later
(See Figure 2).

In this seedling raising pot 1a, the upper end opening edge of the rectangular tubular side wall portion 3 is substantially square, and one linear slit S is formed in the central portion of one side thereof. For example, a concave wall portion 4 that is recessed toward the inner surface of the side wall portion 3 is integrally formed integrally with the side wall portion 3 at the center of one side of the substantially rectangular tubular side wall portion 3, and the upper end opening of the concave wall portion 4 is formed at the upper end opening. To form a part of the upper edge opening edge of the side wall portion 3 and integrally form the top edge portion 5, and the slit S is formed in the top edge portion 5.

In all the drawings including FIG. 1, the side wall portion of the seedling raising pot 1a is shown with a thickness of about 1 mm for convenience of drawing, but this thickness is about 0.2 mm,
Even if a plurality of nursery pots are stacked, they are not bulky. In addition, although the bottom of the seedling raising pot 1a is circular in all the drawings, a substantially rectangular shape is also possible, and it is usual that a drainage hole, unevenness for reinforcement and the like are formed on the bottom. Not shown.

As shown in FIG. 1 (A), the top edge portion 5 is a laterally trapezoidal resin thin plate extending inwardly from the center of one side of the substantially square upper end opening edge of the side wall portion 3, and the top edge portion 5 is a top edge portion. A slit S is formed in the shape of a single horizontal letter at the substantially central portion of 5. The slit S has one label 20 as shown by the chain line in FIGS. 1 (B) and 1 (C).
When it is removably inserted, the label 20 is retained and the label 20 is retained. Further, a guide groove 6 is formed in the slit peripheral portion on the upper surface of the top edge portion 5 so that the label 20 can be easily inserted into the slit S as needed, and the slit S is formed at the bottom of the guide groove 6. . The guide groove 6 is a groove having a V-shaped or U-shaped cross section that slides the lower end of the label 20 inserted into the slit S from directly above and guides it to the slit S.

The label 20 is a thin hard plate made of plastic or the like as shown in FIG. 5, and has a label body 20a in which the names, characteristics, photographs of the seedlings grown in the seedling raising pot 1a are specified, and a label body 20a. It has a wedge-shaped insertion portion 20b that integrally extends from. The slit S is a cut or the like into which the insertion portion 20b of the label 20 is inserted with some frictional resistance. The total length between both ends of the slit S corresponds to the width of the insertion portion 20b of the label 20,
The inserted label 20 is set so that it cannot be easily removed. Details of the dimensional relationship between the label 20 and the slit S will be described later with reference to FIG.

The seedling raising pot 1a shown in FIG. 1 is a single item.
A plurality of these are manufactured collectively in the state of the composite seedling raising pot 1Wa shown in the plan view and front view of FIGS. 2 (A) and 2 (B).
The combined seedling raising pot 1Wa shown in FIG. 2 is formed by arranging seedling raising pots 1a of the same shape in a plane of 4 rows and 6 columns, and the upper end opening edges of the side wall portions 3 of the adjacent seedling raising pots 1a can be easily hand-held. It is connected so that it can be cut.

FIG. 2 (A) shows a state in which a pair of adjacent seedling raising pots 1a are connected at a point P at the black circle shown in FIG. 2 (A). In such a 1-point connection type compound seedling raising pot 1Wa, when one seedling raising pot 1a is pulled with one hand in a state where soil is put in each seedling raising pot 1a, it can be easily torn from the adjacent seedling raising pots. To be separated.

Further, the composite nursery pot 1W shown in FIG.
In a, all of the 6 × 4 = 24 seedling-growing pots 1a have slits S. In the case of growing seedlings or selling them over the counter in the composite seedling raising pot 1Wa, for example, a frame-shaped case 30 of a hard resin molded product as shown in the plan view and the front view of FIGS.

The frame-shaped case 30 has a recess 31 for accommodating one seedling raising pot 1a in a horizontal and vertical array of 6 rows and 6 columns.
4 = 24 places. By storing each seedling raising pot 1a of the composite seedling raising pot 1Wa in the recess 31 of the frame-shaped case 30, the shape of the flexible seedling raising pot 1a is stabilized, and the soil 11 is put in each seedling raising pot 1a as shown in FIG. The seeds and seedlings are grown up and sold in stores in this state. Alternatively, each seedling raising pot 1a is separated from the combined seedling raising pot 1Wa and stored in the recess 31 of the frame-shaped case 30, and the soil 11 is put into each seedling raising pot 1a to grow seeds and seedlings. 1a is sold over the counter.

As shown in FIG. 4, a plurality of seedling raising pots 1a individually separated from the composite seedling raising pot 1Wa are stacked and stored or transported. The two seedling raising pots 1a are superposed on each other such that the inner surface of the concave wall portion 4 of the lower seedling raising pot 1a slides on the outer surface of the concave wall portion 4 of the upper seedling raising pot 1a to be superposed. In addition, each vertical wall of the concave wall portion 4 is tapered so that they can be easily polymerized.

At the stage of seedling growth and over-the-counter sales shown in FIG.
The label 20 is inserted into the seedling raising pot 1a as needed. When the inserting portion 20b of the label 20 is inserted into the slit S formed in the top edge portion 5 of the concave wall portion 4 of the seedling raising pot 1a, the inserting portion 20b extends along the outer surface of the concave wall portion 4 and the soil 11 in the seedling raising pot 1a The seeds and seedlings in the soil are not damaged by the label 20 because they do not enter into. Since the label 20 is inserted into the slit S while being guided by the guide groove 6, the inserting work of the label 20 can be easily and quickly performed with one hand by one-touch type. Also, as shown by the chain line in FIG.
When adjacent to another seedling raising pot 1a in a state, the label 20 inserted into the slit S of one seedling raising pot 1a is along the outer surface of the side wall portion 3 of the adjacent seedling raising pot 1a, so that the adjacent seedling raising seeds 1a There is no fear of being inserted into the pot 1a by mistake.

As shown in FIG. 5 (A), the nursery pot 1a
If the total length of the slit S is L, the maximum width of the wedge-shaped insertion portion 20b of the label 20 is set to be less than L. By inserting the insertion portion 20b into the slit S and frictionally engaging both ends of the slit S with part of both sides of the V-shape of the insertion portion 20, the total length L is set so that the label 20 is difficult to pull out from the slit S. It The locking force between the slit S and the label 20 in the label withdrawing direction is
It is doubled by forming the following notches 21 on both sides of the insertion portion 20b.

For example, a pair of lateral V-shaped notches 21 are formed at the same height on both sides of the V-shaped insertion portion 20b, and the lower sides of the pair of notches 21 are aligned horizontally, and the lower side and the insertion portion 20b are formed. The lateral V-shaped protrusion-shaped engaging portions 22 are formed on both sides. W1>L> W2, where W1 is the width between the tips of the pair of locking portions 22, and W2 is the width between the tips of the pair of notches 21.
Set to the dimensional relationship of.

When the insertion portion 20b of the label 20 is inserted into the slit S as shown in FIG. 5A, the pair of locking portions 22 of the insertion portion 20b first come into contact with both ends of the slit S,
When it is further inserted, the label 20 and the insertion portion 20b are elastically deformed to each other so that the locking portion 22 rides over both ends of the slit S, and both ends of the slit S are fitted into the notches 21 as shown in FIG. The upper edge of the stopper 22 has a slit S
It is locked to the lower surface of the top edge portion 6 formed with.

Therefore, when the label 20 is pulled out from the slit S, the upper end edge of the locking portion 22 is locked to the lower surface of the top edge portion 6 and cannot be easily pulled out. W1>L>
By appropriately setting the dimensional relationship of W2 based on the hardness of the material of the label 20 and the material of the seedling raising pot 1a, the label 20 can be easily inserted into the slit S manually, but the purchaser of the seedlings can easily do it by hand. You can make sure that you don't miss it.

The shape of the slit S in the length direction may be arbitrary, and a concrete example thereof is shown in FIGS. 6 (A) to 6 (D). Figure 6
The slit S1 of (A) has a linear shape, and the total length is L.
Each slit S2, S shown in (B) to (D) of FIG.
Reference numerals 3 and S4 are specific examples of a curved shape including a polygonal line shape, and the total length of each is L. The slit S2 of FIG. 6 (B) extends a linear slit S2 ″ of the same length at the angle θ in the same direction at both ends of the linear slit S2 ′. The slit S3 of FIG. 6 (C) is a V-shaped slit. Yes, the slit S4 in FIG. 3D is a circular arc slit.

In the case of the curved slits S2, S3 and S4 shown in FIGS. 6B to 6D, the tongue portion 5'inside the curved slit of the top edge portion 5 is easily deformed by inserting the label. As a result, the label insertion work becomes easier, and the label elastically deforms to fit the curve of the tip of the tongue portion 5'and the locking force with the label becomes stronger. Excel. Also, the curved slits S2, S3, S4
In the above, the tilt direction of the label inserted into this can be regulated. For example, the curved slit S2 in FIG. 6B regulates the tilt direction of the label 20 as shown in FIGS. 7 and 8.

FIG. 7A shows a state in which the soil 11 is put in the seedling raising pot 1a and the seedlings 12 are grown. The seedling raising pot 1a is of a label post-insert type in which the label 20 is inserted on the rear side of the seedling 12, and the slit S2 in this case has a broken line slit S2 ″ facing outward as shown in FIG. When the label 20 is inserted into S2, the label 20 is tilted so that the lower end of the label 20 comes into contact with the inner surface of the concave wall portion 4 by the action of the tongue piece portion 5'outside the slit S2. Body 20a is seedling 1
The label body 20a is easily seen when the seedling 12 is visually observed from the left side direction (the direction of the broken line arrow) in FIG. The angle θ between the straight line slit S2 ′ and the broken line slit S2 ″ in the slit S2 that regulates the label inclination is appropriately about 135 °.

The seedling raising pot 1a shown in FIG.
0 is a label front insertion type which is inserted in the front side of the seedling 12, and the slit S2 in this case has a broken line slit S2 ″ facing inward as shown in FIG. 8 (B).
When the label 20 is inserted into the label 2, the label
Leans. Due to the inclination of the label 20, the label body 20a is inclined to the front side and the rear side of the seedling 12, so that the label body 20a can be easily seen when visually observing the seedling 12 and the like from the right side of FIG. 8A.

Next, the seedling raising pot 1b of the embodiment shown in FIGS. 9 (A) and (B) and FIG. 10 will be described. This seedling raising pot 1b has two levels of height from the seedling raising pot 1b of the label 20 to be inserted. I am able to change to. As shown in FIG. 10, concave step portions 4 and 4 are formed at two positions of the upper end opening edge of the rectangular tubular side wall portion 3 of the seedling raising pot 1b, and the respective top edge portions 5 and 5 have different total lengths L1. , L2 slits S ′, S ″ are formed. Labels 20 are provided as shown in FIG. 9 corresponding to the slits S ′, S ″ of different lengths.
A pair of notches 23, 25 are formed at different heights on the upper and lower sides of the V-shaped both sides of the insertion portion 20b, and a pair of locking portions 24, 26 are formed at the lower side of the notches 23, 25. .

As shown in FIG. 9 (A), the inserting portion 20b of the label 20 is inserted into the slit S'of the seedling raising pot 1b having the longer total length L1 and the upper stage locking dimensioned corresponding to the total length L1. The portion 26 is locked to both ends of the slit S ′ to determine the height H1 of the label body 20a protruding from the pot 1b. Further, as shown in FIG. 9 (B), the insertion portion 20b of the label 20 is connected to the entire length L of the seedling raising pot 1b.
2 is inserted into the longer slit S ″, and the lower locking portions 24 dimensioned to correspond to the short overall length L2 are locked to both ends of the slit S ″ to project from the seedling raising pot 1b of the label body 20a. Determine the height H2 to do. The difference between the different heights H1 and H2 is the difference between the upper and lower locking portions 2 of the label 20.
It corresponds to the steps of 4, 26.

In the seedling raising pot of Fig. 10, there is the convenience that the label height can be selected in two stages by forming two slits S ', S "having different lengths. May be performed by forming two slits having different lengths on the top edge portion 5 of the concave wall portion 4 formed at one location on the side wall portion 3 of the seedling raising pot 1b.
When the concave wall portions 4 are provided at a plurality of positions of the cylindrical side wall portion 3 to form a plurality of label mounting slits as in the seedling raising pot 1b shown in Fig. 1, the larger the number of concave wall portions, the less the soil that can be stored. Therefore, it is suitable to have two concave wall portions.

The combined seedling raising pot 1Wb of the embodiment shown in FIG. 11 is a combination of 24 seedling raising pots 1a and 1c of two types in a 4 × 6 vertical and horizontal arrangement. One kind of seedling raising pot 1a is a seedling raising pot similar to that shown in FIG. 1 and has one slit S, and the other kind of seedling raising pot 1c is a so-called conventional product without slits. The former seedling raising pots 1a are arranged at an arbitrary number smaller than 24, for example, 6 at 6 places where the odd-numbered rows and the odd-numbered columns intersect, and the latter seedling-growing pots 1c are placed at the remaining 18 points in the vertical and horizontal directions.

The combined seedling raising pot 1Wb shown in FIG. 11 is housed in the frame-shaped case 30 shown in FIG. 24, and soil is put in each seedling raising pot 1a, 1c for over-the-counter sale. In this case, seedlings of the same kind are grown in all the seedling raising pots 1a and 1c, and the label 20 is inserted only in the seedling raising pot 1a having the slit S. Therefore, the number of labels required for one composite nursery pot 1Wb is small, and the seedlings of the unlabeled nursery pot 1c are easy to see.

The composite seedling raising pot 1Wc of the embodiment shown in FIGS. 12A and 12B is the composite seedling raising pot 1W shown in FIG.
This corresponds to a group of b divided into 4 groups of 2 rows and 2 columns. In this seedling raising pot 1Wc, one seedling raising pot 1a with slits and the remaining three seedling raising pots 1c without slits are connected in series. All four seedlings are of the same type, and only one seedling is grown. The label 20 is inserted and sold over the counter.

In addition, the 12 seedling pots 1a ″ on the right side are of the label pre-insertion type (type of FIG. 8). In this case, the 12 seedling pots 1a ′ on the left side are suitable for seeding seedlings suitable for the post-labeling type. Done, 12 seedling pots on the right 1
In "a", seedlings suitable for the label front-mounting type are grown and sold over the counter in the state of the composite seedling raising pot 1Wd.

The seedling raising pot 1d of the embodiment shown in FIG. 14 is a round pot in which a substantially cylindrical side wall portion 3 extends around the periphery of a circular bottom portion 2. The side wall portion is similar to the square seedling raising pot shown in FIG. Three
A slit S is provided in the top edge portion 5 of the concave side wall 4 formed in a part of. It is desirable that the round seedling pot 1d is used by being housed in a case (not shown) that holds the cylindrical side wall portion 3 in a cylindrical shape so as not to be greatly deformed. The basic structure of the round seedling raising pot 1d is the same as that of the seedling raising pot of FIG. 1, and the usage example is also the same as that of the seedling raising pot of FIG.

The seedling raising pot 1e of the embodiment shown in FIG. 15 is obtained by partially changing the shape of the top edge portion 5 of the seedling raising pot 1d shown in the plan view of FIG. 14 (A). That is, FIG.
The cylindrical side wall portion 3 of the round-shaped seedling pot 1d of (A) is in a state where the portion where the concave wall portion 4 and the top edge portion 5 are present is reinforced by the top edge portion 5, and the cylindrical side wall portion 3 The top edge portion 5 of the upper end opening edge is less likely to be deformed than others, and when the upper end opening edge of the side wall portion 3 is deformed indefinitely, the top edge portion 5 is deformed so that its upper surface is twisted. It may be difficult to insert the label into the slit S of the top edge portion 5. The round seedling pot 1e shown in FIG. 15 is partially modified in anticipation of the deformation of the cylindrical side wall portion 3.

In the round seedling pot 1e of FIG. 15, the outer edge 5e of the top edge portion 5 forming a part of the upper end opening edge of the cylindrical side wall portion 3 is a straight line. In addition, this outer edge 5e

According to the present invention, the label inserted in the upper opening edge of the nursery pot of the flexible resin container or the slit formed in the opening edge extension between the nursery pots is the soil in the nursery pot. Since it is inserted along the outer surface of the side wall of the nursery pot without being inserted into the seedling, there is no concern that the seedlings in the soil will be damaged by inserting the label. In addition, since the labels inserted in the slits are locked at both ends of the slits and cannot be easily removed, the trouble of falling the labels attached to the seedling raising pot and the trouble of pulling out the labels due to the carelessness of the seed and seed purchaser are reduced. In particular, label management for seedling pots sold over-the-counter and for compound seedling pots in which multiple seedling pots are connected becomes easier, and the value added is high for sellers of seeds, and the label is easy for buyers of seeds to see. It is possible to provide a seedling raising pot in which the seeds and seedlings are of the same type and a combined seedling raising pot.
