Definitions

  • a closure includes a cap member having a flexible sidewall adapted to engage a lip around the neck of a container.
  • An outer member surrounds the cap member and includes a side wall closely engaging the flexible side wall to limit the expansion thereof. Removal of the closure is facilitated by depressing the outer member toward the neck and simultaneously pressing against the outer side wall to pivot the closure away from the neck.
  • closure employs an arrangement requiring two simultaneous conflicting motions to facilitate removalof the closure.
  • An example of such closures ispresently used for some childrens aspirin containers, and employs a single cap member having a resilient insertinsidethe cap. This closure is adapted to only mate witha container having a specific latch-andcam lip on the neck, such that removal is caused by first.
  • Moller in US. Pat. No. 3,434,614, teaches a closure having a singlecap member with a resilienttop and a lipengagingrim around the periphery thereof. Removal of this closure is facilitated by simultaneously pressing in the resilient top and lifting the rim away from the lip.
  • the present invention comprises a closure adapted to be secured on the neck of a container of the type having a lip surrounding at least a portion of the periphery of the neck.
  • the closure comprises a cap member adapted to be fitted over the neck, and has a flexible side wall adapted to engage the lip. Means are included for limiting the expansion of the flexible side wall.
  • FIG. 1 is a cross sectional side view of a closure in accordance with the present invention.
  • FIGS. 2 and 3 are cross-sectional side views of the closure of FIG. 1, depicting the manner in which removal of the closure is facilitated.
  • FIG. 4 is a cross-sectional side view of a second embodiment of a closure in accordance with the present invention.
  • FIGS. 5 and 6 are perspective views, partially crosssectioned, of portions of the closure of FIG. 4.
  • FIG. 7 is a cross-sectional side view of a third embodiment of a closure in accordance with the present invention.
  • FIGS. 8 and 9 are perspective views, partially crosssectioned, of portions of the closureof FIG. 7.
  • the closure 10 includes a cap member 18 which'is adapted to fit over the neck 12.
  • the cap member'l8" has a flexible sidewall 20 which surrounds the neck'l2, and includes a rim 22 engaging the lip 16.
  • the cap member 18 and the flexible side wall'20' are integrally formed from a compliant "material having a highelasticity-factor. I
  • the expansion limiting means “comprises a noncompliant outer member 24h'avinga side wall'26' surrounding and closely engaging the flexible sidewall 20'of the cap member 18.
  • the outer member 24"and the associ ated side wall 26 are integrally formed'froma material' having a low elasticity factor, such as aluminum, for ex ample.
  • Resilient means such as a spring 30,'are inter posed between the cap member-l8 and the outer member-24.
  • the closure further comprises means for coupling the outer member 24 to the cap member 18 when the outer member is depressed in a direction toward the neck 12.
  • the coupling means contemplates an opening 32 in the outer member 24 which is substantially axial with the direction toward the neck 12.
  • the openin g2 is defined by an inner wall 33 with the spring 30 interposed between the inner wall and the outer side wall 26.
  • the cap member 18 includes a stem 34 extending away from the cap member axial with and into the opening 32.
  • the stem 34 preferably has a cross-sectional shape and dimension proximal to the cap member 18 corresponding to the shape and dimension of the opening 32, in order that the periphery of the opening engages the proximal portion of the stem when the outer member 24 is depressed toward the neck 12, as will be more fully described below.
  • the dimension of the portion of the stem 34 distal to the cap member 18 is smaller relative to the like dimension of the proximal portion.
  • the outer member 24 is initially pressed toward the neck 12 of the container 14, as shown by arrows 40. Due to this movement, the spring 30 is compressed against the cap member 18, relieving the bias of the spring and thereby causing the pressure of the rim 22 against the lip 16 to be relaxed. This relaxation of pressure is allowed by virtue of the downward movement of the crimp 28 away from the rim 22. Additionally, the periphery of the opening 32 in the outer member 24 engages the stem 34.
  • the second of the two conflicting motions is applied as follows. While the outer member 24 is maintained in this depressed position, the outer side wall 26 is pressed in a direction away from the neck 12 at a point distal from the lip 16 (note arrow 42).
  • the rim 22 is moved over the lip 16 in the vicinity below the pressure point on the outer side wall 26.
  • the closure 10 is then moved about a fulcrum 44 and away from the container 14.
  • the engagement of the periphery of the opening 32 to the stem 34 looks the outer and cap members 24, 18 together and assists in transferring the force from the sideward pressure against the outer side wall 26, into the movement of the rim 22 over the lip 16.
  • this closure arrangment referred to generally as 50, comprises a cap member 52 having a flexible side wall 54 surrounding the neck 12, and further including a rim 56 engaging the lip 16.
  • the closure 50 includes an outer member 58 having an outer side wall 60 surrounding and closely engaging a portion of the flexible side wall 54 of the cap member 52.
  • the outer member 58 includes a thickened portion 62 at the extremity of the outer side wall 60, serving a similar purpose as the crimp 28 of the closure 10 in FIG. 1.
  • the cap member 52 of closure 50 further includes a generally cone-shaped resilient member 64 extending into the space between the cap member and the outer member 58.
  • the outer extremity of the resilient member 64 is dimensioned such as to engage the outer side wall 60 when the outer member 58 is depressed toward the neck 12.
  • the cone-shaped resilient member 64 serves the function of the spring 30 and the closure 10 of FIG. 1, and also serves the function of the stem 34, in that engagement of the resilient member 64 with the outer side wall 60 assists in transferring the sideward force to movement of the rim 54 over the lip 16.
  • FIGS. 7 through 9 A third embodiment of the present invention is shown in FIGS. 7 through 9.
  • This embodiment comprises a closure, referred to generally as 70, having a cap member 72 similar to the cap 52 of FIGS. 4 and 5, and which includes a resilient cone-shaped member 74.
  • the cap member 72 includes an upwardly extending cylindrical stem 76 having supporting struts 78 disposed around the inner periphery thereof.
  • the closure further includes an outer member 80 having an outwardly beveled side wall 82 engaging the cap member 72 only at the rim 84 when the outer member is not depressed.
  • the outer member 80 includes an opening 86, the periphery of which is adapted to engage to cylindrical stem 76 of the cap member 72 when the outer member 80 is depressed toward the neck 12. The cylindrical stem 76 and the opening 86 thus assist removal of the closure 70 in a manner similar to the stem 34 and opening 32 of the closure 10 in FIG. 1.
  • a closure in accordance with the present invention has several advantages.
  • the requirement of two simultaneous conflicting motions necessary to remove the closure is relatively difficult, and is believed to meet the minimum requirements discussed above.
  • the closure is adapted for use with a variety of containers.
  • the closure is rugged and can be massproduced using low cost plastic extrusion and molding technology.
  • cap member adapted to fit over said neck and having a flexible side wall adapted to engage said lip;
  • a closure as recited in claim 1 wherein said expansion limiting means comprises an outer member having a side wall surrounding said flexible side wall of said cap member.
