A splash-proof closure for use with liquid holding containers is a one-piece molded structure and includes a body portion with a cap portion, and a hinge integrally formed therebetween. The body portion includes a liquid outlet and a vertically, integrally formed, upwardly extending cap-stopping resilient post for preventing the cap portion from moving towards the liquid outlet during the dispensing mode. The cap portion includes a somewhat domed upper wall which acts as a cam for bending the cap-stopping post at a 45°angle to the body portion when the cap portion is closed, and a closing post integrally formed on the domed wall interior for sealing the liquid outlet when the cap portion is closed on the body portion. The liquid outlet, the cap-stopping post, the closing post and the hinge are all generally along the same line, perpendicular to the hinge axis.

A plastic closure, primarily useful in conjunction with viscous liquid holding containers, comprising: a body portion including a tubular skirt having a longitudinal axis, an open bottom and a closed upper wall, said skirt having an internal periphery and an external periphery, said upper wall having an external diameter and including a top surface and a bottom surface, and a dispensing aperture extending through said upper wall, said tubular skirt forming an annular shoulder at its upper end extending about said upper wall; a cap portion, integrally formed on said body portion, including a tubular wall having a central axis, an open bottom end and a closed domed upper wall having an apex, said tubular wall having an internal diameter slightly larger than the external diameter of said body portion upper wall to provide a tight mating fit therebetween, and the bottom end of said tubular wall being adapted to seat on said annular shoulder; a hinge, located in a plane perpendicular to said axes, for integrally joining said cap portion to said body portion, and including a thinned hinge line between said cap portion and said body portion, for allowing said cap portion to rotate thereabout close on said body portion; a cap-stopping resilient post, integrally formed on said skirt upper wall adjacent the peripheral edge of said upper wall and extending upwardly vertically and parallel to said longitudinal axis, for preventing the movement of said cap portion toward the dispensing aperture when the closure is uncapped; cam means, integrally formed as part of and defined by a portion of said domed upper wall lying between said hinge and said apex, for bending said cap-stopping post to an approximately 45°angle relative to said skirt upper wall when said cap portion is closed on said body portion and for stopping against said cap-stopping resilient post when the closure is uncapped, said cam means being in a plane located approximately 45°above said skirt upper wall when said cap portion is closed on said body portion; finger-tab means, integrally formed on said tubular wall located opposite said hinge to extend radially outwardly from said tubular wall in a plane perpendicular to said central axis, for providing a region to grasp said cap portion for movement on or off of said body portion; and closing post means, integrally formed on said domed upper wall in the region between said apex and said finger-tab means and extending vertically downwardly parallel to said axes, for reception within said dispensing aperture when the closure is capped; said closing post, the dispensing aperture, said cap-stopping resilient post, said cam means and said finger-tab means all lying along a line extending through and perpendicular to the axis of said hinge.
