Document Type and Number:
Japanese Patent JP3899441
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To manufacture a double-chamber tube at a low cost by utilizing an existent mold by providing a protrusion which makes an external tube and a mouth of an internal tube fit in a mouth of the external tube and a helically fitting part which helically fits in the internal tube, and connecting them by an adapter whose inside is partitioned into two paths.
SOLUTION: An adapter 3 which connects an exterior tube 1 and an internal tube 2 comprises a cylindrical part 4 and a helically fitting part 9. An engaging protrusion 8 formed on the top end outer periphery of the cylindrical part 4 engages with a roof face of a mouth 1a of the external tube 1, so that the adapter 3 and the external tube 1 are securely fitted in. The inside of the cylindrical part 4 is partitioned by a partition wall 7 and a content 12 housed in the external tube 1 is extracted to the outside through a lateral hole 11 via a path 5. On the other hand, a male screw 2a of the internal tube 2 is helically fitted in a female screw 9a formed in the inside of the helically fitting part 9, so that the internal tube 2 is connected to the adapter 3 and a content 13 in the internal tube 2 is extracted to the outside through a path 6.
