Molded lid assembly with primary and secondary latching features

A lid for removable closure over a frusto-conically shaped container having a bottom including an annular seating portion, a sidewall extending upwardly therefrom to a top portion including a rim structure having an upwardly disposed rim bead, an outwardly disposed side surface portion of given diameter and an outwardly accessible engaging region below said rim bead having an upper contact surface, comprising:

• a discoidal lid top portion formed of resilient plastic material extensible across said container top portion to an outer periphery locatable adjacent said rim structure;
• a skirt assembly integrally formed with said lid top portion and extending downwardly from said periphery to a lower edge locatable below said engaging region upper contact surface;
• a parting groove extending continuously about said skirt assembly to define upper and lower skirt portions;
• hand graspable means coupled with said lower skirt portion for effecting the removal of said lower skirt portion while maintaining said skirt upper portion intact with said lid top portion;
• a primary latching assembly integrally formed with said skirt assembly and including;
• a plurality of discrete lid lock pocket assemblies formed integrally with said skirt assembly and defining a lock chamber intermediate the inwardly disposed side of said skirt assembly and said container sidewall top portion;
• an interference lug coupled with said skirt lower portion at narrow fold regions at a said lid lock pocket assembly for pivotal movement about said fold region into said lock chamber and into a securing orientation deriving abuttable contact with said engaging region upper contact surface to effect substantially rigid restraint in compression between said fold region and said upper contact surface at said abuttable contact, and resiliently deformable toward the inside surface of said skirt assembly when said skirt assembly is being positioned over said container rim structure,
• each said interference lug being removable from said skirt assembly with removal of said skirt lower position;
• a secondary latching assembly including:
• a lid rim disposed at the said lid top portion outer periphery and having a bead conforming interior surface nestable in seating adjacency with said upwardly disposed container rim bead;
• and
• a detent defining ridge formed integrally with the interior surface of said skirt assembly upper portion at a location for snap-on engagement with said rim structure upper contact surface.

A lid for removable closure over a container having a bottom and sidewall extending upwardly therefrom to a top portion including a rim structure having an upwardly disposed rim bead, an outwardly disposed side surface portion and an inwardly extending engaging region formed inwardly of and below said rim bead and having an upper contact surface, comprising:

• a lid top portion formed of resilient plastic material extensible across said container top portion to an outer periphery locatable adjacent said rim structure;
• a skirt assembly integrally formed with said lid top portion and extending downwardly from said periphery to a lower edge locatable below said engaging region upper contact surface;
• a parting groove extending continuously about said skirt assembly to define upper and lower skirt portions;
• hand graspable means coupled with said lower skirt portion for effecting the removal of said lower skirt portion while maintaining said skirt upper portion intact with said lid top portion;
• a primary latching assembly integrally formed with said skirt assembly and including:
• a plurality of discrete, spaced interference lugs formed with and extending from said skirt lower portion for resilient movement into a securing orientation deriving abuttable contact with said engaging region upper contact surface to effect substantially rigid restraint in compression between said lower skirt portion and said upper contact surface at said abuttable contact, and resiliently deformable toward the inside surface of said skirt assembly when said skirt assembly is being positioned over said container rim structure,
• each said interference lug being removable from said skirt assembly with said skirt lower portion;
• a secondary latching assembly including:
• a lid rim disposed at the said lid top portion outer periphery and having a bead conforming interior surface nestable in seating adjacency with said upwardly disposed contaier rim bead, and
• a detent defining ridge formed integrally with the interior surface of said skirt assembly upper portion at a location for snap-on engagement with said rim structure upper contact surface.
