Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flower water retention bag for holding a water supply liquid supplied to a flower without leaking it, and a method for forming the same.

[0002]

2. Description of the Related Art A technique relating to this type of water retaining bag is disclosed in, for example, Japanese Patent Application Laid-Open No. 8-172910 and Japanese Patent Application Laid-Open No. 8-17291.
It is described in Japanese Patent Publication No. 1 and the like. The former technique is to fill a liquid in a flexible container made of thin rubber or the like, insert a stem of a plant into the container, and close the mouth of the container by its contracting force. In the latter technique, the liquid is contained in a container made of a material having a contracting force, and the mouth of the liquid is closed by a water-absorbing polymer. According to these conventional containers, the container gradually contracts as the cut flowers absorb water, and the contracting force makes it easier for the water to come into contact with the stems, and therefore it is considered that continuous water supply to the cut flowers is easy.

[0003]

However, since the former container has its mouth closed by the contracting force of its material, water is easily leaked when external pressure is applied to the container when inserting the stem. In addition, the latter container requires a carrier (sponge, etc.) to carry the water-absorbing polymer, which complicates bag-making work,
There is a problem that the powdery polymer has poor adhesion to the stem until the water is sufficiently supplied, and the stability of the stem is insufficient during that period.

Therefore, another container is disclosed in, for example, Japanese Patent Laid-Open No. 10-4787. This container has a shape-reinforcing reinforcement portion on its side and a through hole smaller than the stem diameter in the upper portion. Of these, the reinforcement part suppresses deformation of the container due to external pressure, and the through hole suppresses water leakage when inserting the stem by tightening around the stem like a check valve by the elastic force of the material of the container. . However, in this container, since it is necessary to provide a reinforcing portion by a resin molding method such as blow molding, the cost becomes high, and
If the stem has irregularities, there is another problem that the penetration hole expands and water leaks easily from there.

Therefore, an object of the present invention is to provide a water retaining bag for a flower and a method for forming the same, which can reliably seal the periphery of the stem regardless of the shape of the stem and prevent water leakage due to external pressure or the like.

[0006]

According to the present invention, a stalk of a flower is inserted into a bag body of a water retaining bag, and a filling material is filled around the stalk, and the mouth of the bag body is closed by the filling material. Solves the problem. Specifically, the bag body of the water-retaining bag is divided into upper and lower parts, and an upper pocket and a water storage part are formed respectively. A water supply liquid for flowers is stored in the water storage part, and the stem inserted into the bag body is immersed in the water supply liquid. An upper end of the upper pocket opens at the mouth of the bag body, and a bottom of the upper pocket is partially formed so as to pass through to the water storage portion.
The flower stem is inserted into the bag body through the opening at the upper end and the insertion hole at the bottom missing portion. By filling the filling material into the upper pocket in this state, the upper end opening and the insertion opening are closed around the stem. The filling material can fill the circumference of the stalk in the upper pocket, thus ensuring that the outer surface of the stalk is sealed even if it has aneurysms or spines.

Further, if the bag body is formed of the heat-welding film packaging material, the water storage portion and the upper pocket can be easily formed by the heat sealing. Therefore, the process of forming the water retaining bag is simple and easy, and the productivity is high.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an embodiment of a water retaining bag 1 for flowers. The water retaining bag 1 contains, for example, one cut flower F. There is no particular limitation on the type of cut flower F, and the water retention bag 1 can be molded in accordance with various types. The height of the cut flower F is approximately 50 cm to 6
Although it is preferably about 0 cm, an appropriate height can be set in consideration of the variety of cut flowers F and marketability, and the size of the water retention bag 1 is also determined accordingly.

As shown in FIG. 1, the water retaining bag 1 has a stem S.
A part of a certain length is inserted from the cut end of. Further, a water storage part 2 is formed in the lower part of the water retention bag 1, and a predetermined amount of water supply liquid W is stored in the water storage part 2. The stem S is inserted into the water storage section 2 and immersed in the water supply liquid W. As the water supply liquid W, a liquid such as tap water or a chemical liquid is appropriately selected.

The water retaining bag 1 is made of, for example, a heat-welding film wrapping material, and a gas palm seal portion 4 is formed at the lower end portion thereof. The palm-sealing seal portion 4 is welded by heat-sealing opposing film packaging materials, and seals the lower end of the water retention bag 1 in this state. The above-mentioned water storage section 2 is formed in the lower portion of the sealed water retention bag 1. A similar gastric seal part 6 is formed at the mouth of the water retaining bag 1,
The mouth is not completely closed. Specifically, the gassho seal portion 6 is discontinuous at almost the center of the mouth, and is open at this discontinuous portion. The stem S is inserted into the water retention bag 1 through this opening.

An upper pocket 8 is formed in the upper portion of the water retaining bag 1, and the upper pocket 8 is a pair of seal lines 1.
It is formed by dividing the above-mentioned water storage section 2 by 0.
These sealing lines 10 are also formed by heat-sealing the overlapping film packaging materials with each other, and therefore, the water supply liquid W does not move from the water storage section 2 beyond the sealing lines 10.

Each of the pair of seal lines 10 is bent in a key shape and arranged symmetrically with respect to the center of the bag body.
The upper end of each seal line 10 is connected to the palm-sealing seal portion 6 and hangs down from the palm-sealing seal portion 6. The tips of the pair of seal wires 10 are opposed to each other with a predetermined gap. Between the tips, the overlapping film packaging materials are not welded to each other, so that the upper pocket 8 is partially missing due to its structure. As shown in FIG. 1, this bottom missing portion becomes the insertion port 12 of the stem S, and the stem S can be inserted into the water storage part 2 through the insertion port 12 from the upper end opening of the upper pocket 8.

As shown in detail in FIG. 2, the upper pocket 8 is filled with a caulking agent 14. The caulking agent 14 fills the inside of the upper pocket 8 and closes the upper end opening and the insertion opening 12 around the stem S.
Further, the caulking agent 14 is adapted to the inner surface of the film packaging material and firmly adheres to it, so that the caulking agent 14 is not easily peeled off. As a result, the water supply liquid W is sealed in the water reservoir 2 and does not leak from the water retention bag 1.

Further, even if the stem S has a bump or a barb, the caulking agent 14 is filled in the upper pocket 8 so as to fill up the circumference thereof, so that the water supply liquid W can be reliably sealed. it can. In particular, even if the stem S has a spine, the film packaging material is not pierced by the spine because the periphery thereof is covered with the caulking agent 14.

The caulking agent 14 is preferably of silicon type, and such caulking agent 14 can be fixed while the upper pocket 8 is filled with the elasticity while maintaining a certain degree of elasticity. However, the caulking agent 14 is not limited to the silicon-based one, and other appropriate materials can be used. The water retention bag 1 of one embodiment is formed by the following procedure, for example.

First, as shown in FIG. 3, a bag-like bag body 16 is formed from a film packaging material. As the film packaging material, it is preferable to use a heat-welding plastic film having a sealant layer, for example. In the case of a tubular film packaging material, the bag main body 16 is obtained by heat sealing the lower end opening of the film packaging material to form the above-mentioned gastric seal section 4. Also, if it is a plain film, it can be folded in two and sealed on both sides, or two laminated films can be sealed on three sides in the same manner as in the bag body 1
6 can be formed.

A pair of gas-sealing seal portions 6 are formed along the mouth of the bag body 16, and a pair of seal lines 10 are also formed. As a result, the upper portion and the lower portion of the bag body 16 are partitioned, and the upper pocket 8 is formed in the upper portion. At this time, the lower part of the bag body 16 becomes the water storage part 2. As described above, since the pair of gassho seal portions 6 are interrupted at approximately the center of the mouth, the upper end opening of the bag body 16, that is,
An inlet 18 for the water supply W and the caulking agent 14 is secured. On the other hand, the bottom of the upper pocket 8 is the above-mentioned insertion port 1
2 is partially out of reach.

The above-described work may be performed after the bag body 16 is formed, or the joint seal portion 6 and the seal line 10 may be formed at the same time when the bag body 16 is molded. Next, as shown in FIG.
The stem S is inserted through 8 and the insertion port 12, and a predetermined amount of the water supply liquid W is injected into the water reservoir 2. Here, either the insertion of the stem S and the injection of the water supply liquid W may be performed first, or both may be performed simultaneously.

Then, the caulking agent 1 is introduced through the inlet 18.
4 is filled and the upper pocket 8 is filled with the water retaining bag 1 of FIG. According to the water retention bag 1 of one embodiment, since the caulking agent 14 is filled so as to cover the periphery of the stalk S in the upper pocket 8, the water supply liquid W is supplied even if the stalk S has a bump or a barb. It can be surely sealed. Further, since the stem S does not come into direct contact with the film packaging material, the film packaging material is protected and its damage can be reliably prevented.

Further, since the caulking agent 14 retains elasticity to some extent even if it is fixed, even if the cut flower F is transported while being contained in the water retention bag 1, the shaking and impact in the transportation process are alleviated. The cut flower F can be protected.
Further, since the caulking agent 14 is filled in the upper pocket 8 without any gap, the water reservoir 2 can be hermetically and watertightly sealed, and invasion of various fungi from the outside can be firmly prevented. For this reason, the incidence of germs in the water retention bag 1 is extremely low, the quality of the cut flowers F is maintained for a long period of time, and the water retention bag 1 can ensure the shelf life of the cut flowers F together with its water retention ability.

If a heat-welding film packaging material is used for the water retaining bag 1, the bag body 16 and the upper pocket 8 can be easily formed. Further, in the process of forming the water retention bag 1, the bag body 16 is formed, and the palm seal portion 6 and the seal line 1 are formed.
When 0 is formed at the same time, the molding time can be shortened and the productivity of the water retention bag 1 is improved. The water retention bag of each of the above-mentioned embodiments and the water retention bag obtained by the molding method thereof are
Regardless of the outer shape of the stalk, the water supply liquid can be surely sealed by closely contacting the outer surface of the stalk. Further, even when external pressure is applied to the water retaining bag, the mouth portion is not expanded by the liquid pressure, and the water supply liquid does not leak undesirably. Therefore, the water supply liquid can be retained for a long period of time in the process of shipping and distribution from the place where the flowers are produced to the market, and the shelf life of cut flowers can be guaranteed. In addition, the flowers can be easily handled even when they are stored in the water-retaining bag, and the transportability of cut flowers and the marketability can be greatly improved.

The present invention is not limited to the above embodiment,
It can be implemented in various modes. For example, the bag body may be made of a transparent or semi-transparent film, or the window may be provided in the bag body so that the remaining amount of the water supply liquid can be visually confirmed. You may attach information, an identification mark, etc. The size of the upper pocket 8 and the sizes of the insertion port 12 and the injection port 18 are not particularly limited, and these sizes can be appropriately set according to the standard of the flower arrangement. Further, the film packaging material may be heat-sealed by a heater block in the process of forming the seal-sealing portion, the seal line, or the like, or impulse sealing or ultrasonic sealing may be used.

Besides, the filling material to be filled in the upper pocket 8 is not limited to the caulking agent 14 of the embodiment, and can be appropriately changed according to the material of the packaging material and the physical properties of the flower.

[0024]

EFFECTS OF THE INVENTION The water retaining bag for flowers of the present invention reliably seals the water supply liquid, and makes it possible to guarantee the long-term shelf life of the flowers of each variety. Further, since the flower is protected by the filler, the flower is not damaged in the transportation process or the bag body is not damaged, and the reliability and the commercial value of the water retention bag can be greatly improved.

In particular, when the heat-welding film packaging material is heat-sealed, the water-retaining bag can be easily formed, resulting in an inexpensive and high-quality water-retaining bag. In addition, the molding method of the present invention has high productivity and can be easily adapted to automation.
