Abstract
A screw-top closure cap having a collapsible spout nesting within a cap and with a portion of the spout seated coaxially within the container neck itself is disclosed. Both the spout and the cap incorporate child-resistant features to prevent unwanted removal of the closure and/or use of the spout.
Claims17
A screw top closure attachable to a container neck having cooperating screw-on features, the closure comprising:
- an closure body having an radial flange, defining a central aperture, and an annular skirt extending axially downward along an outer periphery of the radial flange;
- a collapsible spout having a first invertible cone section with a peripheral container plug seal sealingly engaging the radial flange, a second cone section defining a dispensing aperture along an inner facing, and at least one overcap engagement protrusion positioned on an outer facing of the first and/or second cone section(s) and wherein the first and second cone sections are contiguous so that, when the spout is collapsed, the second cone section nests within the first cone section so as to be at least partially coaxially nested within the annular skirt and, when the spout is extended, the second cone section extends axially above the first cone section;
- and
- an overcap attachable to the second cone section, the overcap having a top panel with an integral pull ring, a deformable skirt extending axially downward along an outer periphery of the top panel, and a child resistant protrusion positioned proximate to a terminal edge of the deformable skirt and wherein the child resistant protrusion engages the overcap engagement protrusion to selectively prevent removal of the overcap from the spout except when the deformable skirt is squeezed with sufficient force to disengage the child resistant and overcap protrusions;
- wherein the child resistant protrusion is a plurality of ratchet teeth formed along an outer facing of the deformable skirt;
- and
- wherein the overcap engagement protrusion includes cooperating ratchet teeth positioned to face inward so as to engage the child resistant protrusion.

- wherein the child resistant protrusion is a plurality of ratchet teeth formed along an outer facing of the deformable skirt;
- and
- wherein an annular overcap plug seal, formed at a transition point between the first and second cone sections, abuts the terminal edge of the deformable skirt.
