<P>PROBLEM TO BE SOLVED: To provide a synthetic-resin delaminated bottle capable of maintaining a content in the same quality for a long period of time. <P>SOLUTION: The synthetic resin bottle includes an outer shell 1 having a cylindrical opening portion 1a and forming an appearance of the bottle, and an inner pouch 2 layered on the inside of the outer shell 1 for pouring out the content stored inside the inner pouch 2 via the opening portion 1a by squeezing the barrel portion of the outer shell 1 to reduce the volume. The inner pouch is formed so as to be separatable from the outer shell. In this case, a cap 3 for sealing the opening portion 1a by removably threadedly engaged with the outer wall of the opening portion of the outer shell 1 is provided at the bottle. The cap 3 includes a top wall 3a opposing to the opening portion 1a of the outer shell 1, and a circumference wall 3b connected to the top wall 3a, and surrounding the side wall of the opening portion 1a to form a storing space inside it. An annular strip 4 is provided at the inside lower end portion of the circumference wall, and is fixed on the circumference wall at one end. The annular strip 4 has a tapered cross-section to shut off the storing space M from outside by resiliently bringing a sealing wall, that extends toward the other surface to form a gap between the inner surface of the circumference wall, into abutment on the base portion of the side wall of the opening portion 1a. <P>COPYRIGHT: (C)2008,JPO&INPIT |
