A blow molded plastics container includes an injection molded annular neck portion which is sealed by injection molding to an annular wall portion of an injection molded top end wall having a part-spherical center portion. The center portion has five circumferentially spaced and upwardly projecting annular lip seals, two of which surround openings within the top end wall. An injection molded rotatable closure snap-fits onto the neck portion and has a mating part-spherical center portion which engages the lip seals. The closure has one opening which is selectively and progressively alignable with the annular lip seals in response to indexing the closure in one direction. An integrally molded one-way latch extends between the center portions of the closure and top end wall and prevents reverse rotation of the closure except between a consumer open position and a sealed reclosable position.

[ The invention having thus been described, the following is claimed:] [1.] A portable container adapted to receive and retain a fluid and to provide for conveniently opening and closing said container, comprising a hollow body defining a chamber for receiving the fluid and including an upper annular neck portion defining an open top for said body, a cap member covering said open top and including a peripheral portion adjacent said neck portion, a fluid-tight connection between said neck portion of said body and said peripheral portion of said cap member, a rotary closure member supported for rotation relative to said cap member and said body, said cap member and said closure member each being formed of a plastics material, an opening within said cap member and an opening within said closure member, said openings being generally aligned at a rotary open position of said closure member to provide for the free flow of fluid from said chamber, said openings being out of alignment at a first rotary closed position of said closure member, an annular sealing member between said closure member and said cap member and surrounding said opening within said cap member, said sealing member forming a fluid-tight seal between said closure member and said cap member, stop members for limiting rotation of said closure member after rotating said closure member from said first closed position to said open position, said closure member being rotatable to a second closed position closing said opening within said cap member, and said stop members provide for reverse rotation of said closure member between said second closed position and said open position.
