A two-piece cap for a water bottle comprises a main cap which has an annular top disk formed with a depending central well having three levels, each of a slightly smaller diameter. The main cap skirt which depends from the periphery of the top disk has an upper cylindrical portion formed with a truncated internal screw thread which merges into a horizontal bead extending about 180.degree. around the interior of the cap and terminates in a reverse thread portion which extends upward to merge with the leading edge of the truncated screw thread. A first vertical score line extends from the bottom edge of lower skirt portion to the upper edge of the slanted portion. A second vertical score line, spaced a short distance from the first vertical score line, extends from the bottom edge of the lower skirt portion to the top disk. A plug having a closed bottom and a smooth exterior fits into the bottom of the well. The plug has an upper taper to assist in inserting the plug into the bottom of the well followed by three levels, each of slightly larger diameter to seal the central well. An external bead limits inward movement of the plug into the well. An internal bead in the upper end of the plug seats in a groove adjacent the upper end of a water dispenser tube.

[ What is claimed is:] [1.] A non-spill cap for a bottleneck used on a water dispenser of the type having a dispenser probe, said non-spill cap comprising a main cap having an annular top, a skirt depending from the periphery of said top, means on said skirt for engagement with the bottleneck, and a well formed in the center of said top, said well having a lower edge, a land having a first diameter formed on the interior of said well immediately above said lower edge, said well above said land being of larger diameter than said first diameter,and a hollow plug detachably received in said well, said plug having a plug skirt having an interior and an exterior, a closed end for said plug skirt, an external bead on said plug skirt dimensioned to engage said lower edge of said well to limit movement of said plug into said well, an internal bead on an end of said plug skirt dimensioned to removably lock into a groove formed around the exterior of the probe, said plug skirt exterior having a maximum second diameter adjacent said external bead, said second diameter being sufficiently greater than said first diameter so that said plug remains in said well solely by friction between said well and said plug at said first and second diameters until the probe is inserted into said well, contacts said plug and detachably locks onto said plug by said internal bead fitting into the groove in the probe, and is subsequently forced from said well by further movement of said probe into said well,said plug skirt exterior having no groove into which said land may be seated.
