Disclosure of Invention
However, the present inventors have conducted studies and, as a result, have found that the method for storing a phosphor described in patent document 1 has room for improvement in terms of the storage stability of the phosphor.
The present inventors have further studied and found that the storage stability of a phosphor can be improved by replacing the atmosphere in a bottle with an inert gas, which is in contact with the powdered phosphor, and by maintaining the inert gas atmosphere in a space between the bottle and an aluminum bag (bag made of an aluminum laminate film), which is not in contact with the phosphor, and completed the present invention.
According to the present invention, there is provided a packaging bag comprising: a phosphor in powder form, a bottle for containing the phosphor, and a bag made of an aluminum laminated film for containing the bottle,
the inside of the bottle and the inside of the bag are kept in an inert gas atmosphere.
Further, according to the present invention, there is provided a packaging box including: the packaging bag comprises a plurality of packaging bags and a buffer material arranged around the packaging bags.

Detailed Description
Hereinafter, embodiments of the present invention will be described with reference to the drawings. In all the drawings, the same components are denoted by the same reference numerals, and the description thereof is omitted as appropriate. The drawing is a schematic view, and does not match the actual size ratio.
In the present embodiment, the front, rear, left, right, and up and down directions are defined as shown in the drawings. However, this is defined in a simple manner for simply explaining the relative relationship of the constituent elements. Therefore, the direction of use and the production of the product of the present invention is not limited.
An outline of the packaging bag of the present embodiment will be described.
The packaging bag of the present embodiment includes a powdery phosphor, a bottle for storing the phosphor, and a bag made of an aluminum laminate film for storing the bottle. The inside of the bottle and the inside of a bag made of an aluminum laminated film (hereinafter referred to as "aluminum bag") in the packaging bag are kept in an inert gas atmosphere.
In the field of phosphor technology, as disclosed in patent document 1, a process of directly encapsulating a phosphor in powder form after production into an aluminum laminate bag is performed. That is, heretofore, attention has been paid to the atmosphere inside the pouch in contact with the powdery phosphor, but attention has not been paid to the atmosphere outside the pouch that is not in direct contact with the phosphor.
However, in recent years, the level of requirements for the properties of phosphors has increased, and high storage stability is required for powdered phosphors. For example, even when a powdery phosphor is exposed only to oxygen or the like, variation in emission characteristics may occur between lots. In addition, when damage is inflicted on the package during transportation, there is a possibility that the interior of the package is unintentionally exposed to the external environment.
In contrast, the present inventors have conducted studies and found that: by replacing the atmosphere in the bottle with the inert gas, which the powdered phosphor is in contact with, and maintaining the space between the bottle and the aluminum pouch (pouch made of aluminum laminate film), which the phosphor is not in contact with, in the inert gas atmosphere, the storage stability of the phosphor can be improved as compared with the aluminum laminate pouch method in which only the atmosphere with which the phosphor is in contact is replaced with the inert gas.
Further, for example, even when an aluminum bag (outer package) is broken, the fluorescent material is contained in the bottle (interior), and therefore is not exposed to the external environment. Therefore, the storage stability of the packaging bag during transportation is also improved.
The phosphor can be stored in the bottle after the aluminum bag is opened. Therefore, the packaging bag of the present embodiment has a structure that is excellent in storage easiness of the phosphor after opening.
Hereinafter, the detailed structure of the packaging bag of the present embodiment will be described with reference to fig. 1 to 3.
Fig. 1 is a schematic diagram showing an example of the structure of a packaging bag 100. Fig. 2 is a schematic diagram showing an example of the structure of the bag 30 constituting the packaging bag 100 of fig. 1, and fig. 3 is a schematic diagram showing an example of the structure of the bottle 20 housed in the bag 30 of fig. 1.
The packaging bag 100 of fig. 1 includes an aluminum bag (bag 30) and a bottle 20 for storing the phosphor 10. In the packaging bag 100, the space between the outside of the bottle 20 and the inside of the bag 30 and the space inside the bottle 20 are each kept in an inert gas atmosphere. The inert gas atmosphere means that the lower limit of the content of the inert gas is 90% or more, preferably 95% or more, and more preferably 98% or more, in terms of volume, of all the gases contained in the space. On the other hand, the upper limit of the content of the inert gas is not particularly limited, and the content of all gases contained in the space may be 100% or less in terms of volume.
The inert gas is not particularly limited as long as it is a gas that does not react with the phosphor, and examples thereof include nitrogen gas and argon gas. These may be used alone, or 2 or more of them may be used in combination.
The pouch 30 of fig. 2 is constructed of an aluminum laminated film. The aluminum laminated film may be a laminated film in which an aluminum layer and a resin layer are laminated. The bag 30 may contain other materials besides aluminum and resin in order to improve gas barrier properties and reduce water vapor transmission rate. The pouch 30 may have a composition formed of an aluminum laminated film.
As the aluminum layer of the aluminum laminated film, for example, aluminum foil or aluminum vapor deposition layer can be used. As the aluminum material, Al-Mn type, Al-Mg type, and Al-Fe type aluminum alloys other than pure aluminum can be used.
Examples of the resin layer of the aluminum laminated film include resin films such as Nylon (NY), Polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), polyvinyl chloride (PVC), polyvinylidene chloride (PVDC), and chlorinated polyethylene resin (SPE). This can improve the gas barrier property of the bag 30. These may be used alone, or 2 or more of them may be used in combination. A resin layer having excellent heat fusion properties is preferably provided as a heat-seal layer in the innermost layer of the bag 30.
The pouch 30 may be laminated with a plurality of aluminum layers and resin layers. The pouch 30 may be formed by laminating 1 or 2 or more resin layers on both surfaces of an aluminum layer. The number of layers of the bag 30 may be, for example, 3 to 10 layers.
The aluminum layer and the resin layer may be bonded to each other by a known method, and for example, bonding may be performed by using a hot press or an adhesive. As the adhesive, a heat-curable adhesive or an ultraviolet-curable adhesive can be used.
The thickness of the bag 30 is not particularly limited, but is 50 to 300. mu.m, more preferably 80 to 250 μm, and still more preferably 100 to 200. mu.m. By being equal to or higher than the lower limit value, the mechanical strength and gas barrier property of the bag 30 can be improved. By being equal to or less than the above upper limit, the upper end side of the bag 30 can be easily bent at the time of packaging, and the handling property of the bag 30 can be improved.
According to JIS Z0222: 1959 (temperature 40 deg.C, relative humidity 90%) and the water vapor transmission rate of the bag 30 is, for example, 0.01g/m2Day-1.0 g/m2Day, more preferably 0.05g/m2Day-0.5 g/m2Day, more preferably 0.08g/m2Day-0.3 g/m2Day. When the amount is within such a range, the storage stability of the phosphor 10 can be improved.
According to JIS K7126-1: the oxygen permeability of the bag 30 measured at 2006 (temperature 23 ℃ C., relative humidity 0%) is, for example, 0.1cm3/(m2·24h·atm)～10.0cm3/(m224 h. atm), preferably 0.3cm3/(m2·24h·atm)～5.0cm3/(m224 h. atm), more preferably 0.8cm3/(m2·24h·atm)～3.0cm3/(m224 h. atm). When the amount is within such a range, the storage stability of the phosphor 10 can be improved.
As the form of the bag 30, for example, a self-supporting bag, a two-side seal, a three-side seal, a four-side seal, or the like can be used. Among them, a self-supporting bag can be used from the viewpoint of the storage property and the preservation property of the bottle 20.
The bag 30 of fig. 2 shows an example of a stand-up bag with a zipper 32.
The pouch 30 is formed by laminating a front material and a back material, each of which is formed of an aluminum laminated film. The face material and back material are heat sealed to the sides at the ends and a bottom heat seal is made at the lower portion between the face material and back material to form a boat shaped bottom 36 in a bottom gusset pocket. The bottom 36 is not particularly limited as long as it is a shape that allows the bag 30 to stand by itself.
The bag 30 may be sealed at least partially by heat sealing. For example, the upper portion (mouth portion) between the front material and the back material may be unsealed before the bottle 20 is stored, and the bottle 20 may be stored in the bag 30 and then sealed by heat sealing. Therefore, the bottle-holding property and the sealing property of the bag 30 can be improved.
The bag 30 of fig. 2 is provided with a zipper 32 capable of resealing the bag 30 at the innermost layer of the mouth portion. After the bag 30 is opened, the mouth of the bag 30 can be opened by the zipper 32. This facilitates storage and removal of the bottle 20 in the bag 30 after opening.
The bag 30 may also be provided with a notch (notch) at the side end between the upper end 34 and the zipper 32 for tearing off the upper end 34.
In addition, a tear line for tearing off a part of the bag 30 may be provided on the surface of the bag 30. The tear line is disposed between the upper end 34 and the zipper 32 and is physically removed from the bag 30 by pulling. Thus, the bottle 20 can be taken out from the bottom of the bag 30 formed by removing a part thereof in a state where the upper end portion 34 is heat-sealed.
The size of the bag 30 may be appropriately selected corresponding to the size of the received bottle 20. For example, the zipper down length may be adjusted based on bottle height. In addition, the width of the bag and the length of the bottom width can be adjusted according to the width of the bottle.
Note that a label for displaying various information may be provided on the surface of the bag 30. The label may be printed directly on the surface of the bag 30 or may be adhered as a printed matter.
An example of the bottle 20 of fig. 3 is made of plastic, and includes: a body 22 for housing the fluorescent material 10, an intermediate cap 26 attachable to the mouth portion 24 of the body 22, and a cap 28 attachable to the mouth portion 24 in a state where the intermediate cap 26 is attached to the mouth portion 24. The intermediate lid 26 can suppress the fluorescent material 10 from contacting and adhering to the lid portion 28. This can prevent the fluorescent material 10 from scattering when the lid 28 is opened and closed.
The body 22 of the bottle 20 may have any shape as long as it can be placed on the floor. The bottom of the main body 22 of the bottle 20 sealed in the packing bag 100 is kept in the state of being held at the bottom 36 of the bag 30. When the packaging bag 100 is stored in the packaging box in a state in which the bag 30 is self-standing, the bottle 20 can also be maintained in a self-standing state.
The inert gas atmosphere is maintained between the outer surface of the bottle 20 sealed in the package 100 and the innermost layer of the pouch 30. In addition, in the interior of the main body 22 of the bottle 20, a portion not filled with the phosphor 10 is kept in an inert gas atmosphere.
The phosphor 10 is not particularly limited as long as it is in a solid state, but a powdery phosphor 10 may be used. The phosphor 10 in the powder state is not dispersed in the solvent or the resin.
The average particle diameter (d50) of the powdery phosphor 10 is not particularly limited, and may be, for example, 1 to 100 μm or 3 to 50 μm.
The average particle size is a particle size D50 in which the cumulative passage (cumulative passage fraction) from the small particle size side is 50% in the volume-based particle size distribution measured by the laser diffraction scattering particle size distribution measurement method.
The phosphor 10 is not particularly limited, and various phosphors such as a phosphor emitting green light, a phosphor emitting blue light, a phosphor emitting yellow light, and a phosphor emitting red light can be used. Specifically, known phosphors such as inorganic phosphors, organic phosphors, fluorescent pigments, fluorescent dyes, and the like can be cited.
More specifically, the phosphor of the phosphor 10 may include a phosphor selected from the group consisting of oxide phosphors (including garnet phosphors such as YAG phosphors, silicate phosphors), oxynitride phosphors (including sialon phosphors such as α -sialon phosphors and β -sialon phosphors), and nitride phosphors (including CASN phosphors, SCASN phosphors, and La phosphors)3Si6N11: ce phosphor and SrLiAl3N4: eu phosphor, etc.), sulfide phosphor, fluoride phosphor (including KSF phosphor, etc.), chloride phosphor, halide phosphor (including halophosphoric acid chloride phosphor, etc.), and aluminate phosphor.
Among them, the phosphor 10 preferably contains at least one selected from the group consisting of an α -type sialon phosphor, a β -type sialon phosphor, a SCASN phosphor and a KSF phosphor in view of the effect of obtaining the stability of the phosphor.
Hereinafter, a method for manufacturing the packaging bag 100 of the present embodiment will be described.
The following method for manufacturing the packaging bag 100 is an example, and various other steps may be adopted.
A bottle 20 for storing weighed amounts of the fluorescent substances 10 and an aluminum bag (bag 30) corresponding to the bottle 20 were prepared.
The bottle 20 and the bag 30 are disposed in the side box in an open state. The atmosphere in the side tank is replaced with an inert gas. In the side box, an intermediate lid 26 and a lid 28 are attached to the main body 22, and the fluorescent material 10 is sealed inside the bottle 20. The bottle 20 is placed into the bag 30. The air in the bag 30 is vented and the zipper 32 is closed. The bag 30 is removed from the side box and its upper end 34 is heat sealed. Thereby, the packaging bag 100 of fig. 1 is obtained.
The following describes the package case 200 according to the present embodiment with reference to fig. 4.
Fig. 4 is a schematic diagram showing an example of the structure of the packaging box 200.
The package 200 of fig. 4 is constructed from a carton, plastic box, or the like 210.
The packing box 200 includes a plurality of packing bags 100 and a cushioning material 220 provided around at least a part of the packing bags 100 in a box 210. The packaging bag 100 can be stored in a state of standing by itself in the packaging box 200. The cushioning material 220 may be disposed between the bottom of the packaging bag 100 and the inner surface of the bottom of the box 210, or may be disposed between the packaging bags 100. The buffer material 220 may be a known buffer material. By transporting the packaging box 200 including a plurality of packaging bags 100, the transport efficiency of the packaging bags 100 can be improved.
The packing box 200 may have a partition for dividing the storage space. The packaging bag 100 can be disposed in each of the divided housing spaces. This can suppress breakage of the packaging bags 100 due to contact with each other.
In the package case 200, the packaging bag 100 can be stored in a state where the upper end portion 34 of the bag 30 is folded back. This can suppress breakage of the mouth of the bag 30.
While the embodiments of the present invention have been described above, these are merely illustrative of the present invention, and various configurations other than the above-described configurations may be adopted.
The packaging bag 100 may include one or more members other than the bottle 20 and the bag 30 as long as the effect of the present invention is not impaired. Examples of the other member include a desiccant.
