Abstract
Abstract A child resistant dispensing closure (10) characterized by a closure member (12) and a lid member (14) which is mounted on the closure member (12) for movement between closed and open positions. A peripheral edge of the lid member (14) abuts an annular shoulder (22) provided on the closure member (12) in the closed position, the point of abutment being concealed by an annular ring (24) provided on the closure member (12). In the closed position, thickened portions provided on the peripheral edge of the lid member (14) engage in recesses formed in the annular shoulder (22). The lid member (14) is adapted to be moved upwardly from the closed to an open position when a user applies with one hand a manual compressive force to a panel provided on the exterior skirt (18) of the closure member (12). This manual force results in deformation of the panel inwardly into a slot formed clearly through an enlarged portion of the shoulder (22). As a result, a slight separation occurs between the peripheral edge of the lid member (14) and the shoulder (22) so as to allow the user, with the other hand and while continuing to compress the panel, to engage the peripheral edge of the lid member (14) for moving the lid member (14) to the open position.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
274 words
A dispensing closure comprising a closure member (12) and a lid member (14), said closure member being adapted to be secured to a container, said closure member being defined by a top surface (20) and an exterior skirt (18), an interior skirt (26) depending from said top surface and being spaced inwardly of said exterior skirt, a dispensing opening (34) provided in said top surface, a shoulder (22) provided on said top surface, a slot (42) formed in a portion of said shoulder, said slot being located between said exterior and interior skirts, a panel member (48) provided on said exterior skirt at the location of said slot, said lid member being connected to said closure member for movement with respect to said closure member from a closed position wherein said lid member closes off said dispensing opening (34) and an open position wherein said dispensing opening is unobstructed, said lid member being defined by a substantially planar top (50) and a dependent skirt (54), said dependent skirt having a peripheral edge, said peripheral edge being adapted to abut said shoulder when said lid member is in said closed position, said lid member being capable of movement from said closed to said open position by a user applying a manual compressive force to said panel member, said panel member being adapted to deform inwardly into said slot in response to said force, said deformation producing a slight separation between said peripheral edge and said shoulder whereby said lid member may be engaged by the user while continuing to apply said manual force such that said lid member may be moved to the open position.
Claim 2
Dependent Claim
274 words
A dispensing closure comprising a closure member (12) and a lid member (14), said closure member being adapted to be secured to a container, said closure member being defined by a top surface (20) and an exterior skirt (18), an interior skirt (26) depending from said top surface and being spaced inwardly of said exterior skirt, a dispensing opening (34) provided in said top surface, a shoulder (22) provided on said top surface, a slot (42) formed in a portion of said shoulder, said slot being located between said exterior and interior skirts, a panel member (48) provided on said exterior skirt at the location of said slot, said lid member being connected to said closure member for movement with respect to said closure member from a closed position wherein said lid member closes off said dispensing opening (34) and an open position wherein said dispensing opening is unobstructed, said lid member being defined by a substantially planar top (50) and a dependent skirt (54), said dependent skirt having a peripheral edge, said peripheral edge being adapted to abut said shoulder when said lid member is in said closed position, said lid member being capable of movement from said closed to said open position by a user applying a manual compressive force to said panel member, said panel member being adapted to deform inwardly into said slot in response to said force, said deformation producing a slight separation between said peripheral edge and said shoulder whereby said lid member may be engaged by the user while continuing to apply said manual force such that said lid member may be moved to the open position.
