The invention described in claim 4 is a storage container characterized in that the pouring member according to any one of claims 1 to 3 is attached to an end of a storage bag made of synthetic resin. .

The pouring member according to claim 1 is formed by fixing a plant-containing resin part and a non-plant-containing resin part, so that a part (the plant-derived material contained in the plant-containing resin part) is carbon. Because it has neutral properties (properties that do not affect the increase or decrease of CO ₂ in the atmosphere even when burned), the environmental impact when it is burned after disposal is extremely small. Moreover, it can be manufactured at low cost by using vegetable waste materials and the like.

In the pouring member according to claim 1 , the contained liquid and other substances do not come into contact with the plant-containing resin parts, so that the plant-containing resin parts do not rot or the plant-derived substances in the plant-containing resin parts do not come into contact with the plant-containing resin parts. There is no possibility that the components of the material will be mixed into the stored material.

The pouring member according to claim 3 exhibits excellent water resistance because external moisture does not come into contact with the plant-containing resin component even in a humid environment or an environment exposed to moisture such as a bathroom. In addition, the plant-containing resin parts do not rot or become moldy due to the influence of external moisture.

The pouring member according to claim 1 has a simple configuration that reliably avoids contact between the stored substance and the plant-containing resin parts, thereby preventing rotting of the plant-containing resin parts and preventing the presence of plant-containing resin parts in the plant-containing resin parts. It is possible to prevent components of plant-derived materials from being mixed into the storage material with extremely high precision.

It is an explanatory view (perspective view) showing a pouring member of a first embodiment. It is an explanatory view (vertical sectional view) showing the pouring member of the first embodiment (a shows the state with the lid attached, and b shows the state with the lid removed). . It is an explanatory view showing a storage container (standing pouch) of a first embodiment (a is a front view, b is a top view). It is an explanatory view (vertical sectional view) showing the pouring member of the second embodiment (a shows the state with the lid attached, and b shows the state with the lid removed). . It is an explanatory view (vertical sectional view) showing a pouring member of a third embodiment. It is an explanatory view (vertical sectional view) showing an example of a change of a pouring member.

The pouring member according to the present invention includes a plant-containing resin part formed of a synthetic resin to which particles of a plant-derived material are added (i.e., a plant-containing resin), and a synthetic resin part to which particles of a plant-derived material are not added (i.e., a plant-containing resin). That is, it is characterized in that a plant-free resin component formed from a plant-free resin is fixedly attached to the plant-free resin component. As synthetic resins used for plant-containing resins or non-plant-containing resins, polyester, polyamide, polyacrylic, polyolefin, etc. can be used, but among these synthetic resins, polyolefins are preferred because they are easier to manufacture. This is preferable because the environmental burden upon disposal is reduced. Such polyolefins include polypropylene, low density polyethylene such as LLDPE (linear low density polyethylene), medium density polyethylene, and high density polyethylene, used alone or in combination of two or more of them. be able to. In addition, when LLDPE is used as a synthetic resin for plant-based resins, the synthetic resin and particles of plant-derived material have good compatibility (compatibility), which prevents voids and cracks inside parts made of plant-based resins. This is preferable because it is extremely difficult to form.

In addition, as the particles of the plant-derived material to be included (filled) in the plant-containing resin, it is preferable to use particles of wood, bamboo, bamboo charcoal, cellulose made from food residue, or a mixture thereof that has been crushed into particles. Can be done. In addition, when using wood materials as plant-derived materials, coniferous trees such as cedar, cypress, pine, spruce, rosewood, quince, teak, mahogany, walnut, oak, beech, ash, etc. Hardwoods such as tung tree, cherry, lauan, and birch, or a mixture thereof can be suitably used. Among such plant-derived material particles, if cedar is ground into particles, the dispersibility of the plant-derived material particles in the synthetic resin will be extremely good, and it will be easier to disperse them uniformly. preferable.

In addition, the size of the particles of the plant-derived material mentioned above is not particularly limited, but if the maximum particle size is 10 to 500 μm, it will be easier to mix with the synthetic resin, and when molding parts made of plant-based resin. This is preferable because a plant-containing resin part having uniform physical properties without spots can be obtained, and the particle size is more preferably 20 to 100 μm, particularly preferably 40 to 60 μm. The maximum diameter of a particle can be obtained as a number average diameter by image analysis using a microscope, and is the average value of the diameters of 100 particles (if the particles are not circular, the diameter at which the particle diameter is the longest). can be adopted. Furthermore, it is preferable to use particles whose surfaces have been subjected to acetylation treatment (treatment with acetylene, etc.) as the particles of the plant-derived material, since the dispersibility in the synthetic resin will be even better. Furthermore, it is particularly preferable to use acicular particles as the plant-derived material particles because the plant-containing resin parts will have good strength.

Further, in the present invention, it is preferable that the particles of the plant-derived material are added in a proportion of 1 to 70% by mass based on the synthetic resin. If the amount of the plant-derived material particles added is less than 1% by mass, it is not preferable because the environmental burden when disposing of the molded plant-containing resin parts, pouring member, and storage container becomes large. On the other hand, if the amount of the plant-derived material particles added exceeds 70% by mass, it is not preferable because it becomes difficult to mix with the synthetic resin, making it difficult to mold, and making it difficult to express the inherent properties of the synthetic resin. The content of the particles of the plant-derived material is preferably 10% by mass or more and 60% by mass or less, particularly preferably 20% by mass or more and 50% by mass or less.

Furthermore, it is also possible to add a compatibilizer to the plant-containing resin together with the particles of the plant-derived material. As such compatibilizers, wax components, surfactants, acid-modified resin compositions, aliphatic ester compounds, polyhydric alcohol esters, fumaric acid, maleic acid, citric acid, stearic acid, polyalkylene glycols, etc. are preferably used. be able to. In addition, among these compatibilizing agents, it is more preferable to use acid-modified resin compositions, and it is particularly preferable to use acid-modified polyolefins (maleic acid-modified polyethylene, maleic acid-modified polypropylene, etc.). By adding such a compatibilizer, the dispersibility of the particles of the plant-derived material in the plant-containing resin becomes even better. Furthermore, when adding a compatibilizer, adjusting the amount of the compatibilizer to 0.1 to 30% by weight will improve the affinity between the synthetic resin and the particles of the plant-derived material, and This is preferable because voids and cracks are less likely to be formed inside the containing resin parts. In addition, it is also possible to add a fungicide to the plant-containing resin, if necessary.

Moreover, the pouring member according to the present invention has a welding part having a welding surface for welding to the storage bag, and a cylindrical spouting part for pouring out the stored items in the storage bag. The shape and structure thereof are not particularly limited, and may have various shapes and structures. In addition, the spouting member according to the present invention may be a two-piece type in which the main body (spout forming body) and the lid (cap) are molded separately, or the spouting member may be a two-piece type in which the main body (spout forming body) and the lid (cap) are molded separately. It may also be a one-piece type integrally molded with a hole in between.

On the other hand, storage containers obtained by mounting the pouring member according to the present invention include pouches (standing pouches), gusset bags with folds on the left and right sides and the bottom, and three-sided bags. In addition, the material for forming the bag body (storage bag) excluding the pouring member of the storage container is a base film such as polyester film, nylon film, polypropylene film, etc., laminated with a thermoadhesive film such as polyethylene film or polypropylene film. A laminated film or the like can be suitably used. Further, a laminate film having three or more layers in which a polyester film, a nylon film, etc. is sandwiched between such laminate films can also be suitably used.

Hereinafter, the pouring member and the storage container according to the present invention will be explained in detail with reference to examples, but the present invention is not limited to the embodiments of the examples, and the present invention is not limited to the aspects of the examples. , can be changed as appropriate.
