  • Gate well 204 is illustrated surrounding the gate 202 and raised portion 206 is illustrated surrounding the gate well 204.
  • the raised portion 206 extends above the highest portion of the gate 202.
  • the gate 202 may be protected from receiving a load from objects, such as a container 100, being placed on the lid 200.
  • stacking guide 208 may be positioned at a periphery of the raised portion 206. However, the positioning of stacking guide 208 may be determined based on the size of the base 102 of the corresponding container 100.
  • a stacking guide aids in guiding the base 102 to the center of the lid 200 and aids in maintaining the base 102 on the lid 200.
  • the stacking guide protrudes upwardly from the periphery of the raised portion 206 and includes a downwardly slanted surface facing the center of the lid 200 that further aids in guiding the base 102 of the container 100 to the appropriate position on the lid 200.

  • the inner skirt 214 may include an inner skirt protrusion 218.
  • the inner skirt protrusion 218 forms an interference fit with the inner surface of the sidewall 104 of the container 100. Because the inner skirt protrusion 218 interferes with the inner surface of the sidewall 104, a contact force may be applied between the inner skirt protrusion 218 and the inner surface of the sidewall 104. This contact force minimizes or prevents liquid from leaking when the container 100 is on its side or upside down.
  • the inner skirt protrusion 218 may extend around the entire lid or a portion thereof. Also, the inner skirt protrusion 218 may extend around the entire lid to form a complete loop such that a starting and ending point of the loop are the same or to form an incomplete loop such that a starting and ending point of the loop are different. In one embodiment of the incomplete loop, the inner skirt protrusion 218 may have a generally helical shape.
  • the inner skirt protrusion 218 may be an angled protrusion. As illustrated in FIG. 7, the inner skirt protrusion 218 includes a first surface 218a extending upwardly and towards the center of lid 200 and a second surface 218b below the first surface 218a that extends downwardly and towards the center of lid 200.
  • the first and second surfaces may have an angle a with respect to one another of between 60 degrees and 170 degrees. In another aspect the first and second surfaces may have an angle a with respect to one another of between 90 degrees and 160 degrees. In another aspect the first and second surfaces may an angle a with respect to one another of between 120 degrees and 150 degrees.
  • the angle ⁇ of the first surface 218a with respect to the inner surface of the inner skirt 214 may be less than the angle ⁇ of the second surface 218b with respect to the inner surface of the inner skirt 214 .
  • the slope of the second surface 218b may be greater than the slope of the first surface 218a, which is believed to provide a better seal.
  • the outer skirt 216 may include at least one protruding ridge 220. As illustrated in FIG. 4, each protruding ridge 220 may be a unitary bulk protruding ridge.
  • the protruding ridge 220 may include an upper surface 220a that extends generally horizontally outward or extends upward or downward while extending outward.
  • the protruding ridge 220 may be positioned under the bead 108, thereby holding the lid 200 to the container 100.
  • the protruding ridge 220 may also include a lower surface 220b that tapers towards the inner surface of the outer skirt. As such, as the lid 200 is being placed on the container 100, the lower surface 220b guides the container into a gap between the protruding ridge 220 and the inner skirt 214.
  • the protruding ridge 220 may be positioned substantially opposite of the inner skirt protrusion 218. As illustrated, the upper surface 220a of the protruding ridge 220 may be elevated slightly above an upper portion of the second surface 218b of the inner skirt protrusion 218. In another embodiment, the protruding ridge 220 may be positioned a little higher or a little lower. In one example, the upper surface 220a of the protruding ridge 220 may be positioned below an upper portion of the second surface 218b of the inner skirt protrusion 218, or below a lower portion of the second surface 218b of the inner skirt protrusion 218.
