DETAILED DESCRIPTION OF THE INVENTION Referring to the accompanying drawings,
An embodiment of the present invention will be described. FIG. 1 is a sectional view showing a cut flower container according to an embodiment of the present invention.
As shown in the figure, this cut flower container 1 includes a container body 1
0 and an inner cylinder 20 housed in the container body 10.

The container body 10 has a substantially circular bottom 12 and an opening 14. The rising portion 12a from the peripheral edge of the bottom portion 12 serving as the ground contact surface to the cylindrical body portion 13 is shown in FIG.
As shown in, the cross section is formed into a curved surface having a substantially arc shape. The radius of cross-section arc of the rising portion 12a can be appropriately determined according to the size and shape of the container body 10, but is preferably 50 to 100 mm.
More preferably, it is 0 to 80 mm. As an example, when the outer diameter at the lower end of the body 13 is about 300 mm, the cross-sectional arc radius of the rising portion 12a is about 75 m.
to m.

The inner cylinder 20 is formed in a hollow cylindrical shape, and is tapered so as to taper from the upper end 20a to the lower end 20b, and in the vicinity of the lower end 20b, outward from the outer peripheral surface. An overhanging annular brim portion 22 is provided. The inner cylinder 20 includes a peripheral edge of the upper end 20 a and the opening portion 14.
Is liquid-tightly sealed between the bottom end 20b and the bottom 1
2, and a predetermined space (for example, about 75 mm) is provided between the lower end 20b and the bottom portion 12.

An annular gap 30 is formed between the outer peripheral surface of the inner cylinder 20 and the inner wall surface of the container body 10.
The gap 30 is provided in the inner cylinder 20 when the container body 10 falls down.
It has a size large enough to hold the water stored below the lower end 20b. For example, when the outer diameter of the body portion 13 is about 300 mm, the lower end 2 of the inner cylinder 20
The outer diameter of 0b is about 150 mm, and the minimum width of the gap 30 in the radial direction is about 150 mm. Further, the radial extension width of the collar portion 22 of the inner cylinder 20 may be appropriately determined in consideration of the radial minimum width of the gap 30 described above, and is, for example, about 5 to 10 mm.

When a cut flower container 1 having the above-mentioned structure is used to convey cut flowers, first, water is poured into the cut flower container 1 and the bottom 12 of the container body 10 and the lower end 2 of the inner cylinder 20.
The water surface W1 is maintained between 0b. Next, a bundle of cut flowers is inserted into the opening 14 of the container body 10, and the tip of the stem is immersed in the water in the container 1 for cut flowers. Since the upper end 20a of the inner cylinder 20 has a larger opening than the lower end 20b, the cut flowers can be easily accommodated. Then, by transporting the cut flowers in this state, it is possible to maintain good freshness. The cut flower container 1 can be used not only for transporting cut flowers but also for storing after transport.

As shown in FIG. 2 (a), when the cut flower container 1 is laid down during transportation, the stored water moves along the inner wall surface of the cut flower container 1, and the water surface is indicated by W2. It becomes a state. Further, when the container 1 for cut flowers is turned upside down as shown in FIG. 2B, the water surface becomes the state shown by W3. As described above, since the gap 30 between the container body 10 and the inner cylinder 20 is large enough to hold the water inside when the container 1 is tilted, the water surfaces W2 and W3 are
It is located below the lower end 20b opening of the inner cylinder 20. As a result, there is no possibility that the water inside will flow out through the inner cylinder 20, and the water can be reliably held in the cut flower container 1.

Further, the rising portion 12a of the container body 10
However, since the cut flower container 1 is formed into a curved surface having a substantially arcuate cross section, water inside the cut flower container 1 smoothly moves along the rising portion 12a without splashing. Thereby, the outflow of water through the inner cylinder 20 can be prevented more reliably. Furthermore, at the time of tipping, the upper end 2 along the inner cylinder 20 is circulated so as to circulate inside the gap 30.
Flow of water from 0a toward lower end 20b (direction of arrow A)
However, since it is directed downward by the flange portion 22 provided in the vicinity of the lower end 20b, the outflow of water can be more reliably prevented also by this.

Next, a method of manufacturing the cut flower container 1 will be described. As shown in FIG. 3, first, the bottomed tubular body 2 having a predetermined shape is manufactured by blow molding. That is, the parison extruded from the die is sandwiched between molds, and compressed air is blown into the parison to expand the parison and bring it into contact with the wall surface of the mold. After cooling, the bottomed cylindrical body 2 that is a molded product is taken out. The material for forming the parison is not particularly limited as long as it is a resin that can be blow-molded and has good bendability, and a polyester resin such as polyethylene terephthalate (PET) can be exemplified.

Next, the cut flower container 1 is completed by bending the opening of the obtained bottomed tubular body 2 inward at the bending portion 2a as shown by the broken line in FIG. That is, in the bottomed tubular body 2, the portion bent inward corresponds to the inner cylinder 20, and the remaining portion corresponds to the container body 10. According to such a method of manufacturing the cut flower container 1,
Not only is the manufacturing easy and the cost can be reduced, but the container body 10 and the inner cylinder 20 are integrally formed.
There is no possibility that the water inside leaks out through the gap between the inner cylinder 20 and the inner cylinder 20. It should be noted that three or more supporting portions projecting inward from the inner peripheral surface of the container body 10 are formed so that the portion of the bottomed tubular body 2 that is bent inward abuts and is supported by the supporting portion. It may be configured, and is particularly effective when the bottomed tubular body 2 is thin.

The position at which the bottomed tubular body 2 is bent inward is
In this embodiment, the diameter is the largest, but it can be bent at any position above it.
As shown in FIG. 3, by forming the bottomed tubular body 2 so as to taper upward, the size of the opening 14 of the container body 10 can be changed according to the bending position, The usability can be improved according to the size and number of cut flowers. At the bending position of the bottomed tubular body 2,
It is preferable to partially form a thin portion such as forming a convex portion along the circumferential direction, so that bending can be facilitated. Further, a plurality of vertical grooves may be formed in the up-down direction of the bottomed tubular body 2 to facilitate cutting flowers in and out.

Although one embodiment of the present invention has been described in detail above, the specific aspect of the present invention is not limited to the above embodiment. For example, in the present embodiment, the entire inner cylinder 20 is tapered, but as shown in FIG. 4, only the upper portion of the inner cylinder 20 may be tapered. As described above, by forming at least the vicinity of the bent portion 2a of the bottomed tubular body 2 in a tapered shape, the bending work can be easily performed.

The method of manufacturing the cut flower container 1 is not limited to the above-described one. For example, as shown in FIG. 5, the container body 10 and the inner cylinder 20 are separately molded, and the container body 10 is formed.
The inner cylinder 20 may be inserted into the opening 14 and the space between the two may be sealed by heat fusion or the like.

Further, in the above embodiment, the container body 1
0 and the inner cylinder 20 may be formed of a film-shaped resin. This allows it to be easily folded when not in use and to be in a compact state. When the container 1 for cut flowers is formed from a film-shaped resin, as shown in FIG. 6, both side edges of the container body 10 are folded inward by, for example, about 3 cm to form the folded portions 18a, 1
It is preferable to form 8b. As a result, when water is poured into the container body 10, the folding parts 18a and 18b are expanded to form the thickness of the container body 10 and the sitting is improved. The container 1 for cut flowers can be formed, for example, by bonding two film-like resins by heat-sealing at the peripheral edge. The folding portions 18a and 18b are preferably formed at both side edges of the container body 10, but may be at the bottom of the container body 10.

Also, the shape of the container body 10 is not particularly limited, and for example, as shown in FIG. 7, the container body 10 may be composed of the housing portion 32 and the bottomed tubular portion 34. The casing 32 is formed in a rectangular cross section, has openings 141 and 142 on the upper surface and the lower surface, respectively, and has a bottomed cylindrical portion 34 extending downward from the peripheral edge of the opening 142 on the lower surface side. There is. The casing 32 has ribs 32 along the outer peripheral surface.
1 is formed and is reinforced so as not to be crushed when it falls. Further, the bottomed tubular portion 34 is reinforced by forming a plurality of vertical grooves (not shown) extending in the vertical direction at equal intervals. A scale (see FIG. 8) is provided on the outer peripheral surface of the bottomed tubular portion 34, which can be used as a standard so that the water level W of the injected water does not flow out at the time of tipping. The joint between the casing 32 and the bottomed tubular portion 34 is preferably formed in an arcuate cross section, so that the water stored in the bottomed tubular portion 34 is smoothly guided to the casing 32 when it falls. Therefore, it is possible to prevent outflow due to water scattering.

The inner cylinder 20 has an opening 1 on the upper surface side of the casing 32.
41 is provided so as to extend downward from the peripheral edge, and a gap 30 is formed between the inner cylinder 20 and the container body 10. The lower end position of the inner cylinder 20 is not particularly limited and is located inside the housing portion 32 in FIG. 7, but may be inside the bottomed cylinder portion 34. The bottomed cylinder portion 34 and the inner cylinder 20 have their axes aligned with each other and are formed so as to taper downward. The cut flower container 1 thus configured can be formed by blow molding using a polyolefin resin material such as polypropylene or polyethylene.

In this cut flower container 1, as shown in FIG. 8, in the state where a plurality of container bodies 10 are stacked, the bottomed cylindrical portion 34 of one container body 10 is connected to the opening 1 of another container body 10.
It is accommodated in the other container body 10 via 41. Accordingly, when a plurality of cut flower containers 1 are conveyed in an empty state, the cut flower containers 1 can be stacked and made compact, and the transportation cost can be reduced.

Further, the casing 32 is, as shown in FIG.
A protrusion 32a is formed on the upper surface and an engagement recess 32b is formed on the lower surface. Then, as shown in FIG. 8, in a state where a plurality of container bodies 10 are stacked, the protrusion 32a of one container body 10 fits into the engaging recess 32b of the other container body 10. Accordingly, when a plurality of cut flower containers 1 are stacked, the cut flower containers 1 can be positioned and prevented from rotating, so that the cut flower containers 1 can be neatly stacked and the state after stacking can be made more compact.

By forming the protrusion 32a to be hollow, for example, the drain 32 can be formed at the position by cutting off the protrusion 32a with a cutter after use.
Thereby, the water poured into the cut flower container 1 can be easily drained from the drain port.

It is also possible to provide a plurality of protrusions 32a and engaging recesses 32b at corresponding positions in a stacked state. Further, the engaging recess 32b may be formed on the upper surface side of the housing 32, and the protrusion 32a may be formed on the lower surface side.

Further, as shown in FIG. 9, instead of providing the protrusion 32a, a drainage port 36 is formed in the casing 32,
The drainage port 36 may be liquid-tightly sealed by the sealing member 38. In this case, the tip of the sealing member 38 is attached to the housing 3
By projecting from 2, the engaging recess 32b can be fitted, and the sealing member 38 can function in the same manner as the protrusion 32a. As the sealing member 38, screws, stoppers,
A cap etc. can be illustrated.

In the various cut flower containers 1 described above, the lower end of the inner cylinder 20 may be covered with a resin film. It is preferable that the resin film has a material and a thickness that allow the holes of the cut flowers to be easily drilled and that is resistant to tearing from the holes. For example, a resin film having a thickness of about 10 to 100 μm and made of a polyethylene film which is the same material as the cut flower container 1 can be used. According to the cut flower container 1 provided with such a resin film, it is possible to maintain the closed state at the lower end of the inner cylinder 20 by inserting the cut flower while making a hole in the resin film at the tip of the cut flower. Water can be more reliably prevented from flowing out of the container. In addition, in this structure, it is preferable to form a water inlet (also a drain) in the container body 10.

[0034]

As is apparent from the above description, according to the cut flower container of the present invention, a container body having a bottom and an open upper portion, and an inner cylinder extending inward from the upper portion of the container body are provided. The inner cylinder has an upper end that opens toward the bottom of the container body and a lower end that communicates with the outside of the container body, with a gap between the outer peripheral surface of the inner cylinder and the inner wall surface of the container. Therefore, even if the container falls down, the water inside can be held in the gap, and the water can be prevented from flowing out of the container regardless of the size of the opening of the container body.

Further, the rising part from the peripheral edge of the bottom of the container body is formed into a curved surface having a substantially arcuate cross section, and a brim portion protruding outward from the outer peripheral surface near the opening at the lower end of the inner cylinder is formed. As a result, the above-mentioned outflow of water can be prevented more reliably.

Further, by folding the opening of the bottomed tubular body inward to integrally form the container body and the inner cylinder, not only the production can be facilitated and the cost can be reduced, but also the container body and There is no risk of water leaking out between the inner cylinder.

Further, by forming the container body and the inner cylinder from a film-shaped resin, it is possible to make the apparatus compact when not in use. Furthermore, by forming folding parts on both side edges of the container body. It is possible to obtain the stability of the posture in the use state.

Further, in a cut flower container having a container body and an inner cylinder, the container body extends downward from an opening peripheral edge of the lower surface and a housing portion having openings on the upper and lower surfaces. A bottomed cylindrical portion, the inner cylinder is formed so as to taper downward from the opening peripheral edge of the upper surface, and a gap is formed between the inner cylinder and the inner wall surface of the container body. With the container bodies stacked,
One of the container bodies is configured such that the bottomed tubular portion is accommodated through the top opening formed in the casing portion of the other container body, whereby a large number of cut flower containers are compact. It can be stacked on top of each other and the transportation cost can be reduced.

In addition, in the case where a plurality of the container main bodies are stacked, a protrusion is formed on one of the upper surface and the lower surface of the casing and an engaging recess is formed on the other, and the projection of one of the container main bodies is formed. The part is configured to fit into the engagement recess of the other container body, and by cutting off the protrusion,
By forming the drainage port in the casing, not only can the cut flower containers be organized and stacked more compactly, but also drainage after use can be easily performed.

Alternatively, the housing portion has a drain port formed on one of the upper surface and the lower surface and an engaging recess formed on the other side, and the drain port can be liquid-tightly sealed by a sealing member. In a state where a plurality of the container bodies are stacked, the sealing member attached to the drain port of one of the container bodies is configured to fit into the engaging recess of the other container body. According to the above, not only can the cut flower containers be organized and stacked more compactly, but also drainage after use can be easily performed.

Further, by covering the lower end of the inner cylinder with the resin film, it becomes possible to more reliably prevent the outflow of water.
