The locking member is covered on the container mouth so as to hold the plug and the holder member is fitted to the outer peripheral sides of a plurality of locking pieces of the locking member. In each locking piece, an upper side part is connected to a lower side part through a thin-walled bending part. The upper side part is locked to the rubber plug from the lower side with the holder member on the outer peripheral side thereof. The lower side part is locked to the container mouth from the lower side by the holder member. Locking projected parts prevent the lower end of the holder member from coming out of the upper side part. |

| Claim: | 1. A container cap which is put on a mouth of a container to top a plug member fitted into the mouth, the cap comprises: a locking member which has a top plate with a rim and a plurality of locking pieces located around the rim; and a holder member which is mounted surrounding an outer periphery of the locking pieces, wherein each locking piece is extended downward from the rim and has a longitudinal extent; wherein each locking piece comprises an upper side part with an outer periphery and a lower side part with an outer periphery connected to the upper side part by a thin-walled bendable part located midway through the piece in a longitudinal direction thereof that functions as a hinge; wherein the upper side part is locked to said plug member to directly engage the plug member from below in a state where the holder member is mounted on the outer periphery of the upper side part thereof; wherein said lower side part is locked to a part of said mouth from below in a state where the holder member is mounted on the outer periphery of the lower side part thereof; wherein said holder member is movable upwards and downwards relative to the locking member; wherein at least one of said holder member and said locking member has a locking projected part which blocks upward movement of the lower edge of the holder member relative to the upper side part of the locking piece as the holder member is moved upwardly from the state wherein the holder member is mounted on the outer periphery of the lower side part, wherein each of the holder member and the locking piece has a locking projected part, the locking projected part of the holder member being formed on an inner periphery of a lower edge of the holder, the locking projected part of the locking piece being formed on the outer periphery of the upper side part; and a connecting part which connects an upper edge of the locking member and a lower edge of the holder and is severable by pushing down the holder member relative to the locking member, whereby with the container cap on the mouth of a container, the holder member can be pushed downwardly relative to the locking member to sever the lower edge of the holder member and allow the holder member to surround the locking pieces so that the upper and lower side parts are thereby maintained respectively against a part of the mouth and the plug from below each of the part of the mouth and the plug to secure the container cap to the container, whereupon upward movement of the holder member causes the locking projecting parts on the holder member and locking pieces to interact so that as the holder member is moved upwardly the locking pieces are repositioned initially causing the lower side parts to bend outwardly at the hinges to separate from below the part of the mouth and thereafter causing the upper side parts to bear against the plug and cause the upper side parts to draw the plug from the mouth as the holder member is moved further upwardly. |
| Claim: | 2. A container cap as set forth in claim 1 , wherein an external diameter of the lower side part of one of the locking pieces is larger than an external diameter of the upper side part of the one locking piece in a state where the holder member is mounted on an outer periphery of the one locking piece. |
| Claim: | 3. The container cap according to claim 1 wherein the thin-walled bendable part is locally thinner than the upper and lower side parts so that the lower side part bends relative to the upper side part at the bendable part that functions as a hinge. |
| Claim: | 4. The container cap according to claim 1 in combination with a container having a mouth and a plug member fitted into the mouth. |
| Claim: | 5. The container cap according to claim 4 wherein the container mouth has an upper edge surface and the plug member comprises a flange that contacts the upper edge surface and an airtight portion that depends from the flange and extends into the container mouth with the plug member fitted into the mouth. |
| Claim: | 6. The container cap according to claim 5 wherein the airtight portion extends a significant distance into the mouth to tightly fit into the mouth. |
| Claim: | 7. A container cap which is put on a mouth of a container to top a plug member fitted into the mouth, the cap comprises: a locking member which has a top plate with a rim and a plurality of locking pieces located around the rim; and a holder member which is mounted surrounding an outer periphery of the locking pieces, wherein each locking piece is extended downward from the rim and has a longitudinal extent; wherein each locking piece comprises an upper side part with an outer periphery and a lower side part with an outer periphery connected to the upper side part by a thin-walled bendable part located midway through the piece in a longitudinal direction thereof that functions as a hinge; wherein the upper side part is locked to said plug member to engage the plug member from below in a state where the holder member is mounted on the outer periphery of the upper side part thereof; wherein said lower side part is locked to a part of said mouth from below in a state where the holder member is mounted on the outer periphery of the lower side part thereof; wherein said holder member is movable upwards and downwards relative to the locking member; and wherein at least one of said holder member and said locking member has a locking projected part which blocks upward movement of the lower edge of the holder member relative to the upper side part of the locking piece as the holder member is moved upwardly from the state wherein the holder member is mounted on the outer periphery of the lower side part. |
| Claim: | 8. A container cap as set forth in claim 7 , wherein each of the holder member and the locking piece has a locking projected part, the locking projected part of the holder member being formed on an inner periphery of a lower edge of the holder, the locking projected part of the locking piece being formed on the outer periphery of the upper side part, and the cap further comprising a connecting part which connects an upper edge of the locking member and a lower edge of the holder and is severable by pushing down the holder member relative to the locking member, and the holder member, the locking member, and the connecting part being integrally molded. |
| Claim: | 9. A container cap as set forth in claim 7 , wherein each of the holder member and the locking piece has the locking projected part, the locking projected part of the holder member being formed on a lower edge of the holder member, the locking projected part of the locking piece being formed on the outer periphery of the upper side part. |
| Claim: | 10. A container cap as set forth in claim 7 , wherein the upper side part directly engages the plug member from below. |
| Claim: | 11. The container cap according to claim 7 wherein the holder member and locking member are configured so that as the holder member is moved upwardly from the state wherein the holder member is mounted on the outer periphery of the lower side part the holder member causes the locking member to draw the plug member from the mouth. |
| Claim: | 12. The container cap according to claim 7 wherein with the locking projected parts are engaged, the locking projected part on the holder acts against the locking projected part on the locking member to thereby cause the locking member to follow upward movement of the holder member. |
| Claim: | 13. The container cap according to claim 7 in combination with a container having a mouth and a plug member fitted into the mouth. |
| Claim: | 14. The container cap according to claim 13 wherein the holder member and locking member are configured so that as the holder member is moved upwardly from the state wherein the holder member is mounted on the outer periphery of the lower side part the holder member causes the locking member to draw the plug member from the mouth. |
| Claim: | 15. The container cap according to claim 7 wherein the holder member and locking member are configured so that as the holder member is moved upwardly relative to the locking member, the locking projected parts engage so that the locking member follows further upward movement of the holder member. |
| Claim: | 16. The container cap according to claim 15 wherein the locking projected part on the holder member is at a lower edge of the holder member and the locking projected parts engage with the lower edge of the holder member above the lower side part so that the lower side part can separate from the mouth. |
