  • the closure further comprises an outer sidewall 60 extending from a lower rim 62 and having respective inboard and outboard surfaces 64 and 66.
  • a top web 70 spans the inner sidewall to enclose the container when the closure is installed.
  • FIG. 10 shows the top web 70 as having a central portion 72 vertically recessed relative to an outer portion 74 and connected thereto via an angled circumferential wall 76.
  • FIG. 9 also shows a vertical/radial web 79 between the inner sidewall and the outer sidewall (see also, FIG. 8). In the exemplary embodiment of FIG. 8, these webs 79 are evenly circumferentially spaced with the exception of one missing web adjacent the latching feature 80.
  • FIG. 8 underside view shows a child-resistant latching feature 80 extending radially inward from the inboard surface 64 of the outer sidewall 60. In the exemplary embodiment, this is formed as an inward diversion of the outer sidewall 60 associated with a complementary recess 81 (FIG. 7) in the outboard surface 66 of the outer sidewall.
  • the complementary feature of the body is a lug 90 (FIG. 11).
  • the exemplary lug 90 extends upward from an upper surface of the shoulder 32 and radially outward from an outboard surface of a lower portion 33 of the neck below the external thread 35.
  • the exemplary feature 90 is formed as a protrusion associated with a complementary internal recess to maintain a generally constant wall thickness. This, for example, may be an artifact of injection blow molding or other blow molding process forming the features.
  • Each of the features 80 and 90 has a respective ramping surface 82, 92 and stop surface 84, 94.
  • the exemplary ramping surfaces are essentially vertical and of slightly off-circumferential orientation. In the exemplary embodiment, both are convex arcs.
  • the arcs are oriented so that during an installing rotation, the ramping surfaces contact each other as the feature 80 is rotated past the feature 90.
  • a ramping action radially outwardly deforms the outer sidewall 60 at the feature 80 locally.
  • the ramping surfaces will pass out of engagement (e.g., when respective apexes 86, 96 pass each other).
  • the outer sidewall will snap back radially to a relaxed condition.
  • an unscrewing rotation will tend to bring the stop surfaces 84 and 94 into contact with each other.
  • the stop surfaces are oriented generally vertically and slightly circumferentially off-radial (e.g., at least 10° or an exemplary 10° to 25° or 10° to 20° or about 15°) in a direction that resists their overriding each other in attempted unscrewing.
  • further unscrewing torque will tend to drive the outer sidewall locally inward to maintain engagement between the features 80 and 90 and prevent unscrewing rotation.
  • the user To facilitate unscrewing rotation, the user must locally outwardly deform the closure body outer sidewall 60 at the feature 80 so as to shift it sufficiently radially outward to override the feature 90.
  • This is done by the provision of a pair of finger actuatable tabs (radial outward projections) 120 and 122 (FIG. 7) on two opposite circumferential sides of the feature 80.
  • the tabs have circumferentially outboard surfaces 124 and 126.
  • the user may pinch the tabs by replacing a thumb on one of these surfaces and a forefinger on the other and squeezing those fingers toward each other.
  • FIG. 7 shows a radial web 83 protruding radially outward along an arc between the tabs.
  • the addition of the web increases required squeezing force to allow the outward shift of the feature 80.
  • This exemplary web extends outward across the recess 81.
  • An exemplary web protrudes by at least about 0.05 inch (e.g., 0.05 inch to 0.15 inch) along the intact portions of the sidewall (away from the recess 81). The amount of protrusion may circumferentially vary. As show, a much greater radial extent is shown at the recess 81.
  • the exemplary pressure relief features comprises a plurality of ramps 200 (four shown in FIG. 13) on the underside of the closure top web 70 at a radial position at least partially overlapping the rim of the container body.
  • the exemplary ramps 200 have a first surface 202 and a second surface 204 as well as an ID surface 206 and an OD surface 208.
  • the first surface 202 is at a pitch corresponding to the thread pitch. This allows the ramps to be released from a mold portion that molds the interior of the closure including the threads. The closure is simply unscrewed from this mold portion.
  • the container may be made using otherwise conventional or yet-developed materials and techniques.
  • Exemplary closure manufacture is by injection molding and body manufacture by blow molding.
  • Exemplary closure material is polypropylene.
  • Exemplary body material is high density polyethylene (HDPE).
  • One variation on conventional techniques involves using a thread of greater than standard depth DT (FIG. 10A) on both neck and closure.
  • the greater radial engagement between the two threads allows positive retention of the closure while allowing the closure to be light and inexpensive to manufacture.
  • Exemplary depth with an approximately 3 inch mouth diameter is in excess of 0.060 inch or in excess of 0.070 inch and up to about 0.100 inch or 0.09 inch with an example of 0.70 inch to 0.80 inch or 0.76 inch. This may be contrasted with a standard thread of 0.046 inch.
  • the extra depth is provided by making the angle of the non-bearing face of the thread closer to radial.
  • This depth is about 50% greater (e.g., at least 30% or 30% to 60% greater) than the SP - 400 Voluntary Standard SP400, International Society of Beverage Technologists drawing 1165379-1 1999/03/10, the disclosure of which is incorporated by reference herein as if set forth at length.
  • the use of "first”, “second”, and the like in the description and following claims is for differentiation within the claim only and does not necessarily indicate relative or absolute importance or temporal order. Similarly, the identification in a claim of one element as “first” (or the like) does not preclude such "first” element from identifying an element that is referred to as “second” (or the like) in another claim or in the description.
