Abstract
A safety dispensing closure and container package in which the closure is affixed to the container so that it cannot be removed, requiring dispensing through a dispensing orifice in the closure top and inhibiting refilling of the container. An internal bead on the closure skirt engages a groove in the container neck and the closure skirt extends into close proximity with a shoulder on the container neck to prevent attempts of prying removal. Tamper indication can also be provided by an integrally molded insert across the dispensing orifice which is removed by a pull tab.
Claims15
A safety dispensing closure and container package comprising, in combination:
- a container having a neck with a shoulder at the base of the neck and an annular groove above said shoulder;
- a closure including a base cap, a lid, and a spaced apart post and slot hinge connecting said lid to said base cap permitting separate molding of said base cap and lid and assembly together at said hinge;
- said base cap having a flat top with a dispensing orifice therethrough and an annular outer skirt extending from the periphery of said top, said outer skirt having an annular bead projecting inwardly therefrom for force-fitting, snap-on retention within said container neck groove, said skirt having a length that when said base cap is snapped onto said container neck, the bottom of said outer skirt will be in such close proximity to said shoulder so as to prevent the insertion of a tool in an attempt to remove said base cap from said container;
- said base cap having an inner skirt concentric with said outer skirt extending from said cap top for sealing engagement with said container neck;
- and said lid being movable about said hinge from a closed position covering said orifice to an open dispensing position.
A safety dispensing closure and container package comprising, in combination:
- a container having a neck with a shoulder at the base of the neck and an annular groove above said shoulder;
- a closure including a base cap, a lid, and a hinge connecting said lid to said base cap;
- said base cap having a flat top with a dispensing orifice therethrough and an annular outer skirt extending from the periphery of said top, said outer skirt having an annular bead projecting inwardly therefrom for force-fitting, snap-on retention within said container neck groove, said skirt having a length that when said base cap is snapped onto said container neck, the bottom of said outer skirt will be in such close proximity to said shoulder so as to prevent the insertion of a tool in an attempt to remove said base cap from said container, said outer cap skirt also having a reduced wall thickness from said annular bead to the bottom thereof whereby any attempt to remove said base cap from said container by prying between the bottom of said cap skirt and said container shoulder will distort the bottom of said cap skirt to provide evidence of tampering;
- a plurality of circumferentially spaced, longitudinally extending strengthening ribs projecting inwardly from said outer skirt located between said cap to and said annular bead;
- said base cap having an inner skirt concentric with said outer skirt extending from said cap top for sealing engagement with said container neck;
- and said lid being movable about said hinge from a closed position covering said orifice to an open dispensing position.
