<p><P>PROBLEM TO BE SOLVED: To provide a multilayered resin-made container which is lightweight and has a thin thickness, has no restriction on components of an adhesive resin layer and a functional resin layer, causes no release by vibration and an impact, has favorable appearance, and has the enough strength of the container. <P>SOLUTION: As a favorable embodiment of the present invention, annular channels in the horizontal direction are formed on the peripheral wall of a body of the container, and intersecting channels intersecting these annular channels are also formed. The depth of the channel bottom of the annular channel is formed deeper than the depth of the channel bottom of the intersecting channel. The channel bottom of the annular channel at an intersecting region between the annular channel and the intersecting channel is formed convex outward, and the depth of the channel bottom at the intersecting region of the annular channel is made equal to the depth of the channel bottom of the intersecting channel. Thereby, as there exists no step at the intersecting region, there exists no stress concentration caused by vibration and an impact, and no release occurs at the intersecting region, and the multilayered resin-made container with favorable appearance and the enough strength of the container can be provided. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
