Definitions

  • the present disclosure relates to child-resistant packages, and more particularly to a package that is adapted to be opened in either of (at least) two child-resistant modes of operation.
  • US 2004/0222181A1 discloses a package having a child-resistant closure with internal lugs cooperating with external lugs on the container neck finish.
  • the closure is removable by laterally squeezing the closure skirt to ovalize the skirt and release the lugs.
  • US 4553678 discloses a package having a child-resistant closure with internal lugs that cooperate with external lugs on the container neck finish.
  • the closure is removable by axially pressing the closure against a spring disposed between the closure and the container neck finish to release the lugs and permit unthreading of the closure.
  • EP 1357049A2 (corresponding to US 6866164B2 ) discloses a child-resistant package that includes a lid hinged to a base and closeable over a dispensing opening in the base. There are opposed-motion child-resistant features that releasably couple the lid to the base.
  • the base is threadable onto a container neck finish, and there are engageable internal lugs on the closure skirt and external lugs on the container finish to prevent unthreading of the closure base.
  • the closure base can be ovalized so that the lugs move out of engagement and the closure can be unthreaded from the container neck finish.
  • a general object of the present disclosure is to provide a child-resistant package, and to provide a closure and a container for such a package, in which the package can be opened to dispense product in either of (at least) two child-resistant modes of operation.
  • the present disclosure embodies a number of aspects that can be implemented separately from or in combination with each other.
  • a dual-action child-resistant package in accordance with the present diclosure includes a container having a neck finish with an open mouth, at least one external thread segment, and at least one external lug spaced from the thread segment and having an angled cam surface facing axially toward the open mouth.
  • a closure has a peripheral skirt, at least one internal thread segment for engagement with the at least one external thread segment on container neck finish an internal angled cam surface on the skirt, at least one internal lug on the skirt for engagement with the at least one external lug on the neck finish, and a flexible resilient spring for engaging the neck finish and biasing the closure away from the neck finish. The closure is threaded onto the neck finish until the internal lug on the skirt moves over the external lug on the neck finish to resist unthreading of the closure from the neck finish.
  • the closure is removable from the neck finish by:(1) squeezing the skirt to ovalize the skirt such that the at least one internal lug on the skirt moves radially and wordly from the at least one external. lug on the neck finish whereupon the closure can be unthreaded from the neck finish, and (2) pushing the closure over the neck finish against the spring until the cam surface on the at least one external lug engages the internal angled cam surface on the skirt to ovalize the skirt until the at least one internal lug on the skirt moves radially outwardly from the at least one external lug on the neck finish whereupon the closure can be unthreaded from the neck finish.
  • the peripheral skirt of the closure preferably includes a first portion on which the at least one internal thread segment is disposed, and a second portion extending from the first portion on which the internal cam surface and the at least one internal lug are disposed.
  • FIGS. 1-11 illustrate a dual-action child-resistant package 20 in accordance with a first exemplary embodiment of the present disclosure.
  • Package 20 includes a child-resistant closure 22 threaded onto the neck finish 24 of a container 26.
  • Container neck finish 24 includes at least one external thread segment 28 for securement of closure 22 in a child-resistant mode of operation.
  • Thread segment is employed in its usual broad sense to include both single and multiple threads, and both interrupted and continuous threads.
  • Neck finish 24 also includes at least one external lug 30, preferably diametrically opposed external lugs 30 as best seen in FIGS. 3 and 9 .
  • Each external lug 30 has an angled cam surface 32 that faces axially toward or in the direction of the open end or mouth of neck finish 24.
  • Cam surfaces 32 preferably are flat, although conical, convex or concave cam surfaces could be employed.
  • Closure 22 includes a base wall 34 having a peripheral flexible resilient annular skirt 36.
  • Skirt 36 includes at least one internal thread segment 38 for engagement with external thread segment 28 on neck finish 24 to secure closure 22 to neck finish 24 in a dual-action child-resistant mode of operation.
  • Internal thread segment 38 is disposed on a first portion of skirt 36 adjacent to base wall 34.
  • a second portion of skirt 36 extending remotely of base wall 34 includes an angled internal cam surface 40.
  • Cam surface 40 preferably is conical, and most preferably extends entirely around skirt 36 except where interrupted by internal lugs as will be described.
  • Internal surface 40 preferably is formed on a portion 42 of skirt 36 that flares radially outwardly at the open edge of the skirt and terminates in a cylindrically extending portion 44.
  • At least one internal first lug is disposed on the lower portion of skirt 36, preferably a pair of diametrically opposed internal first lugs 46 as best seen in FIG. 3 .
  • Each internal first lug 46 preferable has an angled cam surface 48, by means of which lugs 46 ride over lugs 30, ovalizing flexible resilient skirt 36 until internal first lugs 46 snap behind external lugs 30.
  • Each internal first lug 46 preferably has an associated adjacent internal second lug 50 spaced from lug 46 so that external lugs 30 can be received between lugs 46,50. Lugs 50 prevent additional or over-threading of the closure onto the neck finish.
  • a flexible resilient spring 52 is carried by closure 22 for engaging neck finish 24 and biasing closure 22 away from the neck finish. In the illustrated embodiment of FIGS.
  • spring 52 comprises a segmented annular conical spring having angularly spaced segments 54.
  • a liner disk 56 ( FIG. 2 ) preferably is captured between spring 52 and the open end of neck finish 24. Liner disk 56 can be induction or conduction sealed to neck finish 24 after package 20 has been filled with product and closure 22 applied to the neck finish.
  • spring 52 could be a continuous annular spring that engages the neck finish both to seal the package and to bias closure 22 away from neck finish 24.
  • Spring segments 54 preferably extend downwardly and inwardly from closure base wall 34, as best seen in FIG. 11 .
  • spring segments 54 (or a continuous annular spring) could extend from the inside surface of skirt 36 adjacent to base wall 34.
  • Skirt 36 preferably includes a pair of diametrically opposed external finger pads 58 ( FIGS. 1 and 3 ) at 90° spacing from internal lugs 46.
  • closure 22 is removable in either of two child-resistant modes of operation.
  • a first child-resistant squeeze-and-turn mode of operation illustrated in FIGS. 4-5
  • flexible resilient skirt 36 is squeezed at finger pads 58 to ovalize the skirt and thereby move internal lugs 46 radially outwardly with respect to external lugs 30.
  • FIGS. 6-7 The second child-resistant push-and turn mode of operation is illustrated in FIGS. 6-7 .
  • Closure 22 is pushed downwardly against the force of spring 52. During such downward motion of the closure, internal cam surface 40 on closure skirt 36 engages external cam surfaces 32 on external lugs 30 to spread and ovalize the closure skirt. When the closure skirt is sufficiently ovalized, the closure can be unthreaded from the container neck finish.
  • FIG. 8 illustrates package 20 in a non-child-resistant mode of operation in which closure 22 is inverted and received by press fit, snap fit or threaded fit onto the open end of neck finish 24. Examples of such inverted non-child-resistant operation are illustrated in US patent documents 2004/0173561 and 2004/0178165 .
  • FIGS. 12-14 illustrate a dual-action child-resistant package 60 in accordance with another exemplary embodiment of the present disclosure.
  • Package 60 includes a closure 62 secured to the neck finish 64 of a container 66.
  • Neck finish 64 has one or more external thread segments 28 that are engaged by one or more internal thread segments 38 on the flexible resilient peripheral annular skirt 68 of closure 62.
  • Closure 62 includes a base 70 of which skirt 68 is a part.
  • Base 70 also includes a base wall 72 that covers the open mouth of neck finish 64, and a dispensing opening 74 in base wall 72.
  • a lid 76 is coupled to base 70 by a hinge 79 ( FIG. 14 ) so that lid 76 can be pivoted between the closed position illustrated in FIG.
  • Hinge 79 can be of any suitable type.
  • At least one internal lug 78 ( FIG. 13 ) is carried by skirt 68.
  • Skirt 68 preferably has a pair of diametrically opposed internal lugs 78 as shown in FIG. 13 .
  • Skirt 68 also preferably has diametrically opposed external finger pads 58 at 90° spacing to internal lugs 78.
  • Internal lugs 78 engage a pair of diametrically opposed external lugs 80 on container neck finish 64.
  • Closure lid 76 in the closed position, preferably is coupled to closure base 70 by a child-resistant latch mechanism 82.
  • Latch mechanism 82 can be of any suitable type, with the type illustrated in U.S. patent document 2005/0023285 being preferred.
  • closure 62 As closure 62 is threaded onto container neck finish 64, internal lugs 78 on closure skirt 68 engage and ride over external lugs 80 on neck finish 64 until lugs 78 snap behind lugs 80 in the child-resistant position of FIG. 13 .
  • the entire closure 62 can be removed from container neck finish 64 in a squeeze-and-turn first child-resistant mode of operation, in which finger pads 58 are squeezed to ovalize skirt 68 until lugs 78 clear lugs 80, at which point closure 62 can be unthreaded from the container neck finish.
  • the package alternatively can be opened in a second child-resistant mode of operation by releasing latch 82 and pivoting lid 76 away from base 70 to enable product be dispensed through opening 74.
  • the disclosure can as readily be implemented in conjunction with a dual-wall or multiple-wall closure, in which the thread segments are disposed on an inner wall for securing the closure to a container neck finish and, the child-resistance mechanisms are disposed on intermediate and/or outer walls spaced from the inner wall.
  • the exemplary closures are comprised of one-piece plastic shells.
  • additional components can be included, such as sealing liners or discs. The disclosure is intended to embrace these and all other modifications and variations as fall within the scope of the appended claims .
