SYNTHETIC CLOSURE WITH MULTIPLE INTERNAL LAYERS, EACH LAYER HAVING A VARIABLE CROSS SECTION (VCS) ALONG THE CLOSURE LENGTH |
| 摘要 |
<p>A container closure includes an inner core having a non-cylindrical profile created by a variable longitudinal cross-sectional area. One or more outer layers concentrically surround the core and have a cross-sectional area inversely correlated to the inner core so that the overall container closure has an essentially cylindrical profile.</p> |
