The closure includes (1) an attachment wall defining at least one thread for threadingly engaging the container wall thread, (2) an occlusion wall closing the attachment wall to occlude the container opening when the container is in the closed position, and (3) a continuously curving, peripheral, finger-engaging surface which defines (1) a plurality of circumferentially spaced protuberances, (2) a finger-receiving recess between adjacent protuberances, and (3) a finger-engaging rib projecting laterally from each of the protuberances.
Description
- Not applicable.
- Not applicable.
- Not applicable.
- This invention relates to a container closure which can be screwed on and off.
- A variety of packages that include closures or lids on containers have been developed for household products, personal care products, and other products. One type of package includes a container that is internally or externally threaded around the container mouth or opening and includes a closure with a stem or skirt having mating threads for threadingly engaging the container threads.
- It would be desirable to provide an improved closure for use with such packages.
- Additionally, it would be advantageous if such an improved closure could incorporate a structure which could be more easily grasped by the user's fingers for opening the container by unscrewing the closure or for closing the container by screwing the closure onto the container.
- It would be especially desirable to provide a closure gripping structure that would facilitate the rotation of a relatively small closure by enabling the user to generate sufficient torque for screwing and unscrewing the closure relative to the container. It would be particularly beneficial if the gripping structure would allow the user to generate sufficient torque to open a closure even when a tamper-evident, frangible connection is provided between the closure and container. It would also be especially desirable if such a gripping structure was comfortable for the user to grip.
- Preferably, such a structure should provide improved engagement with the user's fingers under wet conditions so as to minimize the tendency of the finger to slip off of the closure.
- Such an improved closure should preferably also facilitate the removal or installation of the closure by a child as well as by an elderly person having impaired manual dexterity or reduced strength.
- It would also be beneficial if such an improved closure could also accommodate, or actually contain, optional features which provide good sealing of the closure to the container and/or which provide initial, tamper-evident frangible connections between the closure and container.
- It would also be advantageous if such an improved closure could accommodate a variety of aesthetically pleasing designs adaptable for use with various containers.
- It would also be beneficial if such an improved closure could readily accommodate its manufacture from a variety of different materials.
- Further, it would be desirable if such an improved closure could be provided with a design that would accommodate efficient, high quality, large volume manufacturing techniques with a reduced product reject rate.
- Preferably, the improved closure should also accommodate high speed manufacturing techniques that produce closures having consistent operating characteristics unit-to-unit with high reliability.
- The present invention provides an improved closure which can accommodate designs having the above-discussed benefits and features.
- According to one aspect of the present invention, a closure is provided for an opening to a container that has a wall around the opening and at least one thread on the wall. The closure is especially suitable for use on a container that has a very small opening.
- The closure is adapted for movement between a closed position occluding the opening and an open position spaced from the opening. The closure includes an attachment wall defining at least one thread for threadingly engaging the container wall thread. The closure also includes an occlusion wall closing said attachment wall to occlude the container opening when the closure is in the closed position. The closure further includes a continuously curving, peripheral, finger-engaging surface which defines (1) a plurality of circumferentially spaced protuberances projecting laterally in relation to the attachment wall, (2) a finger-receiving recess between two adjacent protuberances, and (3) a finger-engaging rib projecting laterally from each of the protuberances. Each protuberance has a portion that is wider than the rib where the protuberance merges smoothly into the rib.
- The improved closure provides an improved peripheral surface region for being gripped by the user's fingers. The peripheral surface minimizes slippage between the user's fingers and the closure. The peripheral surface region can also be readily provided with a different color, as well as a different texture or material, than the rest of the closure.
- The improved closure can also be readily designed to provide a seal within the closure for sealing against the container at the container opening.
- The closure can also be initially connected to the container with a tamper-evident, frangible connection.
- Numerous other advantages and features of the present invention will become readily apparent from the following detailed description of the invention, from the claims, and from the accompanying drawings.
- In the accompanying drawings forming part of the specification, in which like numerals are employed to designate like parts throughout the same,

- FIG. 7 is a cross-sectional view taken generally along the plane7-7 in FIG. 6.
- While this invention is susceptible of embodiment in many different forms, this specification and the accompanying drawings disclose only some specific forms as examples of the invention. The invention is not intended to be limited to the embodiments so described, and the scope of the invention will be pointed out in the appended claims.
- For ease of description, the closure of this invention is described in a typical upright position, and terms such as upper, lower, horizontal, etc., are used with reference to this position. It will be understood, however, that the closure may be manufactured, stored, and used in orientations other than the one described.
- A presently preferred, first embodiment of a closure of the present invention is illustrated in FIGS. 1-5 and is designated generally therein by the
reference numeral 20. Theclosure 20 is adapted to be mounted on a container 22 (FIG. 5). Thecontainer 22 has a lower, body portion (not visible in FIG. 5) which may have any suitable configuration and has a generally annular, upper,neck portion 24 that defines (1) an upper end opening (2) an exterior, male thread orthreads 28, and (3) an optional retention bead orflange 29. Theflange 29 has an frustoconical, upper,peripheral edge 30 and has an annular,planar bottom surface 32. - The container body portion may have a different cross-sectional configuration than the
neck portion 24. The container body portion may have a cross section that is larger or smaller than theneck portion 24. The cross-sectional shape and size of the container body portion may also be generally the same as the cross-sectional shape and size, respectively, of theneck portion 24 so that theneck portion 24 and body portion are not distinguishable from each other except for thethread 28 on the neck portion (andoptional flange 29, if used). - The
container 22 may be a flexible container or may be a substantially rigid container. So long as thecontainer 22 has an opening and a thread form for receiving a closure in threaded engagement to occlude the opening, the detailed design and operation of thecontainer 22 form no part of the present invention. - As shown in FIG. 1, the
closure 20 includes anattachment wall 36 which defines at least one thread 40 (FIG. 4) for threadingly engaging a mating thread 28 (FIG. 5) on the wall of thecontainer 22. In the preferred embodiment illustrated in FIGS. 1-5, the closure includes a set of four lead high-pitch threads 40, and the container includes a set of four lead high-pitch threads 28. Multiple high-pitch threads require less rotation of the closure to install or remove it from the container while still creating a secure connection. A greater or lesser number of threads could be employed. - The
attachment wall 36 has a generally annular configuration, and the wall depends from a generally disk-like top end wall 42 (FIGS. 1 and 4) which may be characterized as “an occlusion wall” for closing the top of theattachment wall 36 to occlude the container opening when theclosure 20 is in the closed position on the container. - As can be seen in FIG. 4, an
annular plug seal 46 depends downwardly from the occlusion wall or endwall 42 within theattachment wall 36. Theplug seal 46 is adapted to be received in the container opening and create a sealing engagement with the container wall that defines the container opening. Other suitable seal structures could be employed, such as a crab's claw-type seal (not illustrated). In some applications, it may not be necessary to provide any particular type of fluid-tight seal per se. The use of a seal, or the particular seal structure per se, forms no part of the present invention. - An optional, frangible, tamper-evident structure50 (FIGS. 1 and 4) may be provided by on the bottom of the
closure 20. A particular type of tamper-evident structure is illustrated in FIGS. 1 and 4, but other types of tamper-evident structures may be employed. Alternatively, theclosure 20 need not have any type of tamper evident structure. The particular tamper-evident structure 50 illustrated in FIGS. 1 and 4 includes aretention ring 52 attached with unitary molded frangible bridges 54 (FIG. 4) to the bottom end of theclosure attachment wall 36. On the inside of theretention ring 52 are a plurality of circumferentially spaced-apartbead segments 56 which are adapted to project inwardly beneath the container neck flange bottom surface 32 (FIG. 5) when theclosure 20 is initially installed on thecontainer 22. As theclosure 20 is initially installed, typically by an automatic capping machine, thebead segments 56 ride down the container neck flangefrustoconical surface 30 and cause thering 52 to expand radially outwardly temporarily and elastically until thebead segments 56 are move downwardly far enough to clear the lower edge of theflange 29 and then snap radially inwardly beneath theflange surface 32. - To assist in initially installing the closure on the
container 22, thering 52 includes an upwardlyopen recess 60 having a leadingengagement wall 62. The bottom edge of theclosure attachment wall 36 includes a downwardly dependingdrive tab 64 having a leading drivingwall 66 for engaging the ringrecess engagement wall 62 during the threading-on process of installing theclosure 20 on thecontainer 22. Because of frictional resistance between thering bead segments 56 and theflange 30 during installation, there maybe a tendency for thefrangible bridges 54 to be subjected to stress as theclosure attachment wall 36 is rotated by the capping machine and as the torque is transmitted through thebridges 54 to thering 52. This could tend to cause undue deformation or failure of one or more of thefrangible bridges 54 if the rotational displacement between theclosure attachment 36 and thering 52 is excessive. Accordingly, the provision of thetab 64 within therecess 60 permits only a small amount of relative rotational displacement between the two portions of theclosure 20 before thetab driving wall 66 engages thering wall 62. At that point, thering 52 is driven directly by thetab 64 which can withstand the torque, thus limiting the relative rotational displacement between thering 52 andwall 36 to a small amount which is readily accommodated or tolerated by the frangible bridges without rupturing the frangible bridges 54. - When the
closure 20 is initially unscrewed from the container by the user for the first time, theretention ring 52 remains held below thecontainer flange 29 while theclosure attachment wall 36 moves upwardly so as to rupture thefrangible bridges 54 and separate completely from thering 52 which remains below thecontainer flange 29 to provide evidence that theclosure 20 has been unscrewed at least an amount sufficient to rupture thebridges 54. - A user can readily unscrew, or screw on, the
closure 20 by using a novel gripping structure 70 (FIG. 4). The grippingstructure 70 includes a continuously curving, peripheral, finger-engaging surface 72 (FIG. 1). The finger-engagingsurface 72 includes a plurality of circumferentially spaced protuberances 74 (FIG. 2). Theprotuberances 74 project laterally in relation to theattachment wall 36. A finger-receiving recess 76 (FIG. 2) is defined between each pair of twoadjacent protuberances 74. Therecesses 76 are adapted to receive a finger or thumb of the user's hand when theclosure 20 is grasped or gripped by the user for rotating theclosure 20 during the process of screwing the closure onto the container or unscrewing the closure from the container. - In the preferred embodiment illustrated in FIGS. 1-5, there are four
protuberances 74, and there are finger-receivingrecesses 76. - The peripheral, finger-engaging
surface 72 also includes a finger-engaging rib 80 (FIG. 2) projecting laterally from each of theprotuberances 74. Eachprotuberance 74 has a portion that is wider than therib 80 projecting therefrom. Eachprotuberance 74 has a reduced width at therib 80 where theprotuberance 74 merges smoothly into therib 80. - In the preferred embodiment illustrated in FIG. 2, each
rib 80 has a convex distal end, and eachprotuberance 74 has a convex portion from which arib 80 projects. Further, in the preferred embodiment, each finger-receivingrecess 76 is defined by generally concave portion of the finger-engagingsurface 72 which smoothly merges with the convex portions of theprotuberances 74 on either side of therecess 76. - As can be seen in FIG. 2, each of the two sides of each
rib 80 projects from one of theprotuberances 74 at a location on the side of the one protuberance that can be defined by an imaginary line that is parallel to the closure rotational axis X (FIG. 1) and that is located on an inflection point of the continuously curving, peripheral finger-engagingsurface 72. - Each
rib 80 is adapted to be engaged by a portion of the user's finger or thumb when the user grasps theclosure 20. - In the preferred embodiment illustrated in FIGS. 1-5, the
protuberances 74 extend from, and surround, an upper portion of theattachment wall 36. Further, eachprotuberance 74 defines aninternal passage 84 having an open top and an open bottom. Thepassages 84 are optional, and may be provided for reducing the amount of material required, for aesthetic reasons, or for other reasons. - The
closure 20 may be made from any suitable material. In the preferred embodiment illustrated in FIGS. 1-5, theclosure 20 is molded from a suitable thermoplastic material, such as polypropylene. To aid in extracting theclosure 20 from the mold components (not illustrated), the bottom end of theclosure attachment wall 36 maybe provided with unthreading apertures 88 (FIG. 3) for receiving a tool (not illustrated) to unscrew the moldedclosure 20 from the mold assembly. - In the preferred embodiment illustrated in FIGS. 1-5, the
attachment wall thread 40 is an internal, female thread. However, if theclosure 20 is intended to be received on a container having an internally threaded opening, then the closure threads would be designed to have an external, male thread form on the exterior surface of the attachment wall 36 (not illustrated). - FIGS. 6 and 7 illustrate a second embodiment of a
closure 20A in accordance with the teachings of the present invention. The second embodiment of theclosure 20A provides different aesthetic design features, but retains the inventive, functional features that are in the first embodiment of theclosure 20 illustrated in FIGS. 1-5 and described above. - In the alternate embodiment of the
closure 20A illustrated in FIGS. 6 and 7, theclosure 20A includes a continuously curving, peripheral, finger-engagingsurface 72A which is identical to the finger-engagingsurface 72 described above with reference to the first embodiment illustrated in FIGS. 1-5. However, theclosure 20A does not have any internal passages like thepassages 84 in thefirst embodiment closure 20 illustrated in FIG. 1. Rather, theclosure 20A includes acentral occlusion wall 42A which extends radially outwardly and merges with a solid, non-apertured portion of the surrounding gripping structure. - The other features of the alternate embodiment of the
closure 20A are identical to the analogous features in the first embodiment of theclosure 20. - If desired, in either the first embodiment of the
closure 20 or the second embodiment of theclosure 20A, the gripping structure may extend further downwardly toward the bottom of the closure. Alternatively, the gripping structure may have a shorter overall vertical thickness or height than what it is illustrated. - The novel gripping structure is easy to grip, and is especially suitable for use with relatively small closures which might be otherwise hard to grip and rotate for unscrewing from a container or screwing back onto a container.
- The gripping structure provides a smooth surface which is comfortable to the user's hand. The protuberances and ribs are especially helpful for accommodating the elderly or children by providing a longer lever arm to generate the torque needed to unscrew the closure or to screw the closure onto the container. Sufficient torque can be generated, even by a child or by an adult with an impaired gripping function, to break a tamper-evident structure.
- The combination of the finger-receiving recesses, protuberances, and ribs defined by the finger-engaging surface on the periphery of the closure accommodates the gripping of the closure with a thumb and one finger, or two fingers, or three fingers in a convenient configuration which is comfortable and which provides an effective grip for a applying sufficient torque to the closure to screw it on or off.
- The novel features of the present closure invention readily accommodate manufacture of the closure, especially by molding from thermoplastic materials.
- It will also be appreciated, in other alternate embodiments (not illustrated), the number of protuberances (e.g.,
protuberances 74 in FIG. 2) and the number of finger-engaging recesses (e.g., recesses 76 in FIG. 2) maybe increased beyond four or reduced below four.
