Field of the Invention The present invention relates to a frit composition for producing an ultraviolet-shielding colorless hollow container glass by a color feeder system when manufacturing a soda-lime glass bottle. That is, the present invention relates to a frit used when a container for protecting the contents from ultraviolet rays is produced by a color feeder method suitable for small lot production.

形等により適当な大きさのものにする。2. Description of the Related Art The galler feeder method is known as one of the continuous production methods for colored glass used in glass containers. In the forehearth of a glass melting furnace, a glass containing a high concentration of colored components is used. This is a method of producing colored glass by adding powder (called a frit for color feeder), particles, pulverized material or melted material to a molten base glass and uniformly mixing the frit with this. This frit is
Mix the raw materials of each component so that the specified glass composition is obtained.
It is heated and melted at a temperature of 50 to 1550 ° C., and made into a suitable size by water-brushing, crushing, molding and the like.
【０００３】従来、カラーフィーダー方式で紫外線を遮
断する無色中空容器硝子を得るフリットとして、紫外線
遮断成分としてＶ2Ｏ5を用いることは知られていた。Conventionally, it has been known to use V 2 O 5 as an ultraviolet ray blocking component as a frit for obtaining a colorless hollow container glass that blocks ultraviolet rays by a color feeder method.

フリットは使いずらいところがあった。However, when V 2 O 5 is used as an ultraviolet ray blocking component and the amount of V 2 O 5 is increased to obtain sufficient ultraviolet ray blocking, the V 2 O 5 has a coloring power. Since it is large, it is difficult to obtain colorless glass produced. Further, when V 2 O 5 is added, there is a drawback that bubbles are likely to be generated, and for this reason, it was difficult to use a frit using V 2 O 5 .

る。On the other hand, in the present invention, CeO 2 having a relatively small coloring power is used as a component for blocking ultraviolet rays, and a decoloring agent is added to this to carry out a decoloring treatment. By virtue of this, it relates to a glass composition of a frit that has a sufficient effect of blocking ultraviolet rays and can obtain a colorless glass. Moreover, this frit enables uniform mixing when added to the molten basic glass by the color feeder method. It has a glass composition that does not easily generate bubbles.

（高濃度着色硝子を希釈する）好ましくない。Function: SiO 2 is a glass network former and is contained in the range of 35-65%. SiO 2 is 3
If it is less than 5%, the water resistance of the glass deteriorates and the glass does not devitrify. If the SiO 2 content exceeds 65%, the solubility of the glass deteriorates and the specific gravity of the glass decreases, which is not preferable due to the nature of the frit (diluting highly concentrated colored glass).

量を減らすことが可能になる。The glass composition of the frit in the present invention contains CeO 2 in an amount of 2 to 30% in order to block ultraviolet rays. If the amount is 2% or less, ultraviolet rays are blocked when it is diluted with colorless glass. There is no effect of and is not practically useful. Also, if it exceeds 30%, it becomes difficult to vitrify,
Undissolved matter is generated and becomes a problem as a frit. N
Although d 2 O 3 is added to the frit of the present invention as a decolorizing agent, if the amount of Nd 2 O 3 is 0.1% or less, the effect for decoloring when diluted with colorless glass is weak. There is no practical use. If it exceeds 5%, purple is generated when it is diluted with colorless glass. TiO 2 itself has an effect of blocking ultraviolet rays, but when used in combination with CeO 2 , the expected effect comes out. Then, by using TiO 2 , it becomes possible to reduce the amount of CeO 2 additionally used.
