Definitions

• the clockwise-disposed lug prevents over-tightening of the closure on the container neck finish and aligns the closure with the container body, while the counterclockwise-disposed lug resists unthreading of closure from the container neck finish when the tab on the closure skirt has been received between the lugs.
• the clockwise-disposed lug that prevents over-tightening of the closure on the container neck finish has a greater radial dimension than the counterclockwise- disposed lug, preferably by being radially thicker than the counterclockwise-disposed lug.
• FIG. 8 is a fragmentary plan view on an enlarged scale of the portion of FIG. 7 within the area 8;
• FIG. 10 is a top plan view of the closure in the package of FIGS. 1-6;
• Inner skirt or wall 46 extends from deck 38 within skirt 44, preferably concentrically with skirt 44.
• Inner wall 46 preferably is cylindrical and has one or more internal thread segments 48 for engagement with external thread segments 30 on container neck finish 28 to secure the closure to the container.
• At least one tab 50 (FIGS.4, 6 and 11) axially extends from inner wall 46, more preferably a pair of diametrically opposed tabs as illustrated. In assembly of closure 24 with container 22, tabs 50 are received, preferably by snap fit, between diametrically opposed pairs of external lugs 52, 53 on container neck finish 28.
• Lugs 52, 53 are contoured so that tabs 50 can ride over and snap between the lugs during application of the closure to the container neck finish, but resist removal of the closure from the container after such assembly as described hereinafter.
• an annular wall 54 extends from deck 38 within inner wall 46 and may be received in plug-sealing engagement with the open end of container neck finish 28.
• Lid 34 preferably includes a base wall 56 having a segmented peripheral skirt 58.
• lid base wall 56 is circular and skirt 58 is part- cylindrical in geometry.
• a pair of spaced walls 60, 62 preferably are disposed on lid base wall 56 within skirt 58 for sealing engagement with dispensing opening wall 42 on base 32, as shown in FIG. 1.
• a latch arm 82 may extend from the edge of 1 id 34 at a position spaced from hinge 36, most preferably diametrically opposite from hinge 36.
• Latch arm 82 is generally T-shaped (FIGS. 2 and 13), having a central leg 84 and a pair of laterally extending tabs 86, 88. Tabs 86, 88 preferably are adjacent to the free end of leg 84.
• Lid skirt 58 may be indented at 58a (FIGS. 10 and 11) to accommodate latch arm 82 within the periphery of skirt 58 (FIG.9).
• a pair of ribs 90 (FIG. 11) may extend along the inner surface of skirt portion 58a within latch arm 82 and onto the inside surface of lid base wall 56 to strengthen skirt portion 58a.
