Abstract
A package having child-resistant and non-child-resistant modes of operation includes a plastic container having a cylindrical finish and at least one external thread on the finish spaced from the open end of the finish. An external circumferentially extending first engagement element is provided on the finish between the external thread and the open end of the finish, and has an outside diameter that is less than that of the external thread. A manually deflectable release element is externally cantilevered from the finish on a side of the thread remote from the open end. A plastic closure has a base wall and a peripheral skirt with at least one internal thread for engagement with the at least one external thread on the finish in a child-resistant mode of operation. There is at least one locking lug on the skirt for releasable engagement with the release element on the container in the child-resistant mode of operation. An annular wall extends from the base wall in a direction opposite from the skirt. A second engagement element is disposed on the inner surface of the annular wall for engagement with the first engagement element on the container finish in an inverted non-child-resistant mode of operation of the closure. In disclosed embodiments of the invention, the engagement elements may comprise circumferential beads or circumferential threads on the container finish and the annular wall of the closure.
Description
- The present invention relates to child-resistant closure and container packages, such as medicinal packages for example, to closures and containers for such packages, and to methods of making such packages.
- Reference is made to U.S. applications (Dockets 17794, 17795, 17926, 17953 and 17956) assigned to the assignee of the present application.
- U.S. Pat. Nos. 5,899,348, 6,039,195 and 6,327,770 disclose closure and container packages that are particularly well suited for prescription applications. The container includes a sidewall with an externally threaded finish and a deflectable release element cantilevered from the finish on a side of the threads remote from the open mouth of the container. The closure includes a base wall with an internally threaded peripheral skirt having locking lugs at the edge of the skirt remote from the base wall. These locking lugs on the skirt cooperate with a locking lug on the deflectable release element of the container to secure the closure to the container in a child-resistant mode of operation. To release the closure, the release element is deflected downwardly toward the container sidewall to move the locking lug on the release element out of engagement with the locking lugs on the closure skirt. A dome extends from the inner periphery of the base wall and has an external thread that is adapted to be received within the open mouth of the container in an inverted non-child-resistant mode of operation of the closure. Although the packages disclosed in the noted patents have enjoyed substantial commercial acceptance and success, improvements remain desirable. In particular, it is desirable to provide a package of this general type in which material and part costs are reduced, and in which the overall height of the package presents a lower profile for handling and storage.
- The present invention embodies a number of aspects that can be implemented separately from or, more preferably, in combination with each other.
- A package having child-resistant and non-child-resistant modes of operation in accordance with one aspect of the present invention includes a plastic container having a cylindrical finish and at least one external thread on the finish spaced from the open end of the finish. An external circumferentially extending first engagement element is provided on the finish between the external thread and the open end of the finish, and has an outside diameter that is less than that of the external thread. A manually deflectable release element is externally cantilevered from the finish on a side of the thread remote from the open end. A plastic closure has a base wall and a peripheral skirt with at least one internal thread for engagement with the at least one external thread on the finish in a child-resistant mode of operation. There is at least one locking lug on the skirt for releasable engagement with the release element on the container in the child-resistant mode of operation. An annular wall extends from the base wall in a direction opposite from the skirt. A second engagement element is disposed on the inner surface of the annular wall for engagement with the first engagement element on the container finish in an inverted non-child-resistant mode of operation of the closure. In disclosed embodiments of the invention, the engagement elements may comprise circumferential beads or circumferential threads on the container finish and the annular wall of the closure.
- The invention, together with additional objects, features, advantages and aspects thereof, will be best understood from the following description, the appended claims and the accompanying drawings in which:
- FIG. 1 is an elevational view of a closure and container package in a child-resistant mode of operation in accordance with one exemplary but presently preferred embodiment of the invention;
- FIG. 2 is a fragmentary sectional view of the package illustrated in FIG. 1;
- FIG. 3 is a fragmentary sectional view on an enlarged scale of the portion of FIG. 2 within the
area 3; - FIG. 4 is a fragmentary sectional view of the package in FIG. 1 in a non-child-resistant mode of operation;
- FIG. 5 is a fragmentary sectional view on an enlarged scale of the portion of FIG. 4 within the
area 5; - FIG. 6 is a fragmentary elevational view of the container in the package of FIGS. 1-4;
- FIG. 7 is a fragmentary top plan view of the container in FIG. 6;
- FIG. 8 is a partially sectioned elevational view of the closure in the package of FIGS. 1-4;
- FIG. 9 is a fragmentary sectional views on an enlarged scale of the portion of FIG. 8 within the area9;
- FIG. 10 is a fragmentary sectional view of a package in accordance with a second exemplary but presently preferred embodiment of the invention in a child-resistant mode of operation;
- FIG. 11 is fragmentary sectional view of the package in FIG. 10 in a non-child-resistant mode of operation;
- FIG. 12 is a fragmentary elevational view of the container in the package of FIGS. 10-11; and
- FIG. 13 is a fragmentary sectional view of the closure in the package of FIGS. 10-11.
- FIGS. 1-4 illustrate a closure and
container package 20 in accordance with one exemplary but presently preferred embodiment of the invention as including acontainer 22 and aclosure 24.Container 22 preferably is of one-piece molded construction of suitable plastic such as polypropylene. Likewise,closure 24 preferably is of one-piece molded plastic construction of suitable resin material such as polypropylene. However, description of closure andcontainer package 20 as comprising a one-piece container and a one-piece closure does not preclude inclusion of other elements in the package, such as a sealing liner secured over the container mouth that must be removed to dispense product from the container, devices to hold down pelletized products such as vitamin tablets within the container, etc. The package can be employed for dispensing prescriptions, medicinal products such as vitamins or aspirin, etc. -
Container 22 includes abody 26 from which afinish 28 integrally extends.Finish 28 includes a first portion 30 (FIGS. 2 and 6) adjacent to and surrounding the mouth at the open end of the finish, and asecond portion 32 contiguous withportion 30 and spaced from the open end of the container. The outside diameter d1 (FIG. 6) ofcontainer portion 30 is less than the outside diameter d2 ofcontainer portion 32. At least oneexternal thread 34 is disposed aroundcontainer finish portion 32. Anexternal bead 36 is disposed aroundcontainer portion 30 at or adjacent to the open end of the container finish, and is thus disposed betweenexternal threads 34 and the open end of the container finish.External bead 36 preferably has an outside diameter equal to the outside diameter d2 offinish portion 32.Bead 36 may be disposed at the open end of the container as illustrated in the drawings, or spaced axially from the open end of the container. (Directional words such as “upper” and “lower” are employed by way of description and not limitation with respect to the upright orientation of the container and package illustrated in the drawings. Directional words such as “radial” and “axial” are employed by way of description and not limitation with respect to the central axis of the container finish or the closure as appropriate.) Arelease element 38 is flexibly and resiliently cantilevered radially outwardly from the lower end ofcontainer finish 28. A locking lug 40 (FIGS. 6 and 7) is carried byrelease element 38.Release element 38 andlocking lug 40 preferably are as disclosed in above-noted U.S. Pat. Nos. 5,899,348,6,039,195 and 6,327,770. The release element and locking lug alternatively but less preferably may be as disclosed in U.S. Pat. No. 5,711,442. The disclosures of these patents are incorporated herein by reference. - Closure24 includes a
base wall 42 and aperipheral skirt 44 with one or moreinternal threads 46. Aflange 48 extends radially outwardly from the lower edge ofskirt 44 remote frombase wall 42 in the preferred embodiments of the invention, and anouter skirt 50 extends from the outer peripheral edge offlange 48.Skirts locking lug 52 is disposed on the internal surface ofskirt 50. Anannular wall 54 extends axially frombase wall 42 in a direction opposite fromskirt 44. In the preferred embodiments of the invention,annular wall 54 is disposed radially inwardly fromskirt 44 and is coaxial withskirt 44. Acircumferential bead 56 extends radially inwardly from the inner surface ofannular wall 54 at a position spaced frombase wall 42. Aseal rib 58 is disposed on the undersurface ofbase wall 42 radially inwardly of and concentrically withskirt 44. In the preferred embodiments of the closure illustrated in the drawings,base wall 42 is of flat planar annular construction, having concentric inner and outer peripheral edges. Internally threadedskirt 44 extends from the outer peripheral edge ofbase wall 42. A projection or plug 60 preferably extends from the inner peripheral edge ofbase wall 42 in a direction opposite fromskirt 44, and is disposed radially inwardly fromannular wall 54.Projection 60 has a flat upper wall on which printing may be molded or otherwise provided to advise a user how to open the package in the child-resistant mode of operation, or that the package is non-child-resistant in the non-child-resistant mode of operation (FIG. 2) of the closure (FIG. 4).Projection 60 preferably is cylindrical, and may be solid or, more preferably, hollow as shown in the drawing. - In the child-resistant mode of operation illustrated in FIGS. 1-3,
closure skirt 44 is threaded overexternal threads 34 oncontainer finish portion 32 until one of the internal locking lugs 52 onclosure 24 rides over lockinglug 40 onrelease element 38. Abutment of the locking lugs prevents counterclockwise rotation of the closure with respect to the finish, and thus prevents removal of the closure from the container in the child-resistant mode of operation.Seal bead 58 on the underside ofbase wall 42 is in engagement with and compressed by the axial end ofcontainer finish 28, as best seen in FIGS. 2 and 3, to seal the package. To remove the closure in the child-resistant mode of operation,release element 38 is pushed downwardly away from the closure skirt. Lockinglug 40 onrelease element 38 is thus moved downwardly with the release element out of locking engagement withlug 52 onclosure 24, so that the closure can now be rotated counterclockwise and unthreaded from the container finish. The reduced diameter ofcontainer finish portion 30 andbead 36 with respect tocontainer finish portion 32 andexternal threads 34permit closure skirt 44 readily to be received over the open end of the container finish. - To
use closure 24 in a non-child-resistant mode of operation, such as for elderly persons with impaired manual dexterity for whom child-resistance is not needed, the closure is inverted to the orientation of FIG. 4. The closure is then pressed downwardly onto the finish of the container so thatclosure bead 56 onannular wall 54resiliently cams wall 54 radially outwardly untilbead 56 is received by snap fit overbead 36 at the end ofcontainer finish portion 30.Bead 56 preferably is rounded or has axially facing slope cam surfaces to assist securement of the closure to the container in a non-child-resistant mode of operation, and to assist removal of the closure. Inward disposition ofannular wall 54 with respect to the outer peripheral edge ofclosure base wall 42 andskirt 44 provide flexibility to the annular wall for resilient receipt by snap fit over the end of the container finish.Beads closure base wall 42. Such abutting engagement cooperates with the engaged beads to seal the package in the non-child-resistant mode of operation. - FIGS. 10-13 illustrate a closure and
container package 70, including acontainer 72 and aclosure 74, in accordance with a second exemplary but presently preferred embodiment of the invention. Reference numerals in FIGS. 10-13 that are identical to those employed in connection with FIGS. 1-9 indicate identical or related components. The discussion of the embodiment of FIGS. 10-13 will concentrate on the differences between this embodiment and that of FIGS. 1-9 already discussed in detail. The primary difference betweenpackage 70 in FIGS. 10-13 andpackage 20 in FIGS. 1-9 is that the closure threadably engages the container finish in the non-child-resistant mode of operation in FIG. 11, as distinguished from the snap-bead engagement in FIG. 4. That is, one or more external threads 76 (FIG. 12) extend circumferentially aroundupper finish portion 30. Thesethreads 76 have an outside diameter that is substantially equal to the outside diameter d2 ofcontainer finish portion 32, so thatclosure skirt 44 is freely receivable over the container finish in the child-resistant mode of operation (FIG. 10). Likewise, one or more internal threads 78 (FIGS. 10 and 13) extend around the internal surface of closureannular wall 54. In the non-child-resistant mode of operation (FIG. 11),annular wall 54 is received overupper finish portion 30 andthreads closure base wall 42. - There have thus been disclosed a closure and container package, a closure, a container, and a method of making a closure and container package that fully satisfy all of the objects and aims previously set forth. The invention has been disclosed in conjunction with two exemplary but presently preferred embodiments thereof, and a number of modifications and variations have been described. Other modifications and variations will readily suggest themselves to persons of ordinary skill in the art. The invention is intended to embrace all such modifications and variations as fall within the spirit and broad scope of the appended claims.
