The durability of the inside coating to the deformation processing in the post-processing of the inside-coated metal container having corrosion-resistivity is improved to reduce minor cracks and peelings as far as possible. In an inside-coated metal container 10 in which a high-degree of deformation processing is applied to the vicinity of an opening of one end after coating the inner surface, the coating films formed by the coating have the first layer 12 with high deformation processing durability laid on an area where the high-degree deformation processing is applied and the second layer 13 with high corrosion resistivity laid on the entire inner surface including the first layer of the metal container. The first layer 12 is made of phenolic epoxy resin coatings containing little phenol component and no pigment, and the second layer 13 is made of phenolic epoxy resin coatings containing much phenolic component and pigment.

What is claimed is: 1. An inside-coated metal container, comprising: a cylindrically-shaped metal container body 11 including a cylindrical body member 14 having a top end and a bottom end, a bottom member 15 connected to the bottom end, a shoulder member 16 having a truncated cone shape connected
What is claimed is: 1. An inside-coated metal container, comprising: a cylindrically-shaped metal container body 11 including a cylindrical body member 14 having a top end and a bottom end, a bottom member 15 connected to the bottom end, a shoulder member 16 having a truncated cone shape connected to the top end, a cylindrical neck member 17 connected to a top of the shoulder member, a curling part 18 winding outward connected to a top of the neck member, and a thread part 17a formed around the neck part, the cylindrically-shaped metal container body is a mono-block container processed by an impact processing, a drawing, or a drawing-ironing; and a coating film including a first layer 12 composed of an phenolic epoxy resin type coating compound having high durability to deformation processing applied to an inner surface of an upper part of cylindrical body member, an inner surface of the shoulder member, and an inner surface of the neck member; and a second layer composed of an phenolic epoxy resin type coating compound having high corrosion resistance applied entirely to an inner surface of the cylindrically-shaped metal container body including the first layer, wherein the first layer is composed of an phenolic epoxy resin type coating compound containing 10 to 30 wt % of a phenol component and the second layer is composed of an phenolic epoxy resin type coating compound containing 20 to 50 wt % of a phenol component; and the amount of the phenol component contained in the first layer is 1 to 10 wt % less than that contained in the second layer. 2. An inside-coated metal container according to claim 1, wherein the coating film further includes a third layer 39 composed of an phenolic epoxy resin type coating compound having high durability to deformation processing of the first layer is applied to an area of the first layer on the second layer. 3. An inside-coated metal container, comprising: a cylindrically-shaped metal container body 11 including a cylindrical body member 14 having a top end and a bottom end, a bottom member 15 connected to the bottom end, a shoulder member 16 having a truncated cone shape connected to the top end, a cylindrical neck member 17 connected to a top of the shoulder member, a curling part 18 winding outward connected to a top of the neck member, and a thread part 17a formed around the neck part, the cylindrically-shaped metal container body is a mono-block container processed by an impact processing, a drawing, or a drawing-ironing; and a coating film including a first layer 12 composed of an phenolic epoxy resin type coating compound having high durability to deformation processing applied to an inner surface of an upper part of cylindrical body member, an inner surface of the shoulder member, and an inner surface of the neck member; and a second layer composed of an phenolic epoxy resin type coating compound having high corrosion resistance applied to a rest of an inner surface of the cylindrically-shaped metal container body, wherein a bottom of the first layer and a top of the second layer are overlapped, wherein the first layer is composed of an phenolic epoxy resin type coating compound containing 10 to 30 wt % of a phenol component and the second layer is composed of an phenolic epoxy resin type coating compound containing 20 to 50 wt % of a phenol component; and the amount of the phenol component contained in the first layer is 1 to 10 wt % less than that contained in the second layer. 4. An inside-coated metal container according to claim 1 or 3, wherein a reduced diameter cylindrical part is formed between the shoulder member and the neck member. 5. An inside-coated metal container according to claim 1 or 3, wherein a third layer composed of Ultra Violet ink is applied to a whole or apart of an inner surface of the a cylindrically-shaped metal container body. 6. An inside-coated metal container according to claim 1 or 3, wherein a third layer composed of hot-melt agent is applied to a whole or a part of an inner surface of the a cylindrically-shaped metal container body. 7. An inside-coated metal container according to claim 1 or 3, wherein the second layer is composed of an phenolic epoxy resin type coating compound containing a pigment and the first layer is composed of an phenolic epoxy resin type coating compound containing no or smaller amount of the pigment than the amount of pigment contained in the second layer. 8. An inside-coated metal container according to claim 1 or 3, wherein the first layer is composed of an phenolic epoxy resin type coating compound using a high-molecular weight epoxy resin and the second layer is composed of an phenolic epoxy resin type coating compound using a low-molecular weight epoxy resin. 9. An inside-coated metal container according to claim 1 or 3, wherein the first layer is composed of a water-based epoxy acrylate resin type coating compound using a high-molecular weight epoxy resin and the second layer is composed of an phenolic epoxy resin type coating compound using a low-molecular weight epoxy resin.
