FIG. 1 , acontainer assembly 10 according to a first preferred embodiment of the invention includes aclosure 12 and acontainer 14, which is best shown inFIG. 4 . As is shown inFIG. 4 ,container 14 includes amain body portion 16, an upstanding generallycylindrical finish portion 18 having at least oneexternal thread 20 thereon and an outwardly extendingannular transfer ring 22 that is positioned adjacent to thefinish portion 18. Although the term transfer ring is generally used specific to plastic containers that are formed from a preform by blowmolding, such as those that are generally fabricated from polyethylene terephthalate, it is to be understood that the term transfer ring as it is being used herein could refer to any structure that is functionally equivalent to the transfer rings described herein with respect to the invention as it is disclosed, including structure on containers that are not formed by using a preform. - Referring again to
FIG. 4 ,transfer ring 22 includes a slightly taperedupper surface 24, a taperedlower surface 26 and anouter surface 28 that forms the outer periphery of thetransfer ring 22. Aradiused transition surface 30 connects the slightly taperedupper surface 24 and theouter surface 28, for reasons that will be described in greater detail below. According to one particularly advantageous feature of this embodiment of the invention, a pair of generally longitudinally extending notches, only one of which is shown inFIG. 4 , are defined in thetransfer ring 22. Eachnotch 32 includes a firstside stop surface 34, a secondside stop surface 36 and abottom surface 38 that defines the bottom of thenotch 32. The first and secondside stop surfaces cylindrical finish portion 18. - Referring again to
FIG. 1 ,closure 12 preferably includes amain body portion 40 that is constructed and arranged to be screwed onto the threadedfinish portion 18 of thecontainer 14.Main body portion 40 includes a top portion ordeck 42 in which a dispensingorifice 44 is defined within a dispensingspout 46 for dispensing a substance from thecontainer 14 when thedispensing closure 12 is in the open position shown inFIG. 1 .Main body portion 40 further includes a downwardly dependingskirt portion 48, and alid member 50 having an integralinternal seal member 54.Lid member 50 is hingedly mounted to themain body portion 40 by ahinge member 52 for movement between a first closed position wherein theinternal plug 54 covers the dispensingorifice 44 and an open position wherein the dispensingorifice 44 is uncovered by theinternal plug 54 and thelid member 50. - In the illustrated embodiment,
closure 12 further has tamperevident locking structure 56, which includes a removable tamperevident band 58 that is frangibly mounted to themain body portion 40 by a number of integrally molded frangible bridges.Lid member 50 includes a pair of locking teeth 61 that engage the removable tamperevident band 58 when the closure is closed during the manufacturing process. In order to remove the tamper-evident band 58 to open theclosure 12, a consumer will grasp apull tab 60 in order to tear the removable tamperevident band 58 away from themain body portion 40 by fracturing the frangible bridges. - Referring now to
FIG. 2 , it will be seen that the downwardly dependingskirt portion 48 has aninner surface 62 on which at least one raisedinternal thread 64 is defined. According to one particularly advantageous feature of the invention,retention structure 66 is provided on theclosure 12 that will engage with thecontainer 14 in such a manner as to frustrate efforts that may be made by the consumer or by potential wrongdoers to remove theclosure 12 from thecontainer 14. In this first embodiment of the invention,retention structure 66 is embodied as a pair of inwardly extendingprojections 68, each of which is unitary with theinner surface 62 of theskirt portion 48 of themain body portion 40 of theclosure 12. Each inwardly extendingprojection 68 is oriented substantially as to be generally parallel with a longitudinal axis of the substantiallycylindrical skirt portion 48 of theclosure 12, and includes first and secondlateral engagement surfaces 70 and a taperedlower end 72. Taperedlower end 72 is preferably given a convex radius, but it could alternatively be configured as a linear taper.FIG. 3 provides an alternative view of the underside of theclosure 12 and illustrates the second inwardly extendingprojection 68. The two inwardly extendingprojection 68 are preferably diametrically opposed from each other, corresponding to the diametrical opposition of thenotches 32 that are defined in thetransfer ring 22 of thecontainer 14. - When the
closure 12 is being screwed on to thecontainer 14 during the packaging process, the inwardly extendingprojections 68 will as theclosure 12 is nearly fully screwed on to thecontainer 14 begin to contact theupper surface 24 of thetransfer ring 22, with the taperedlower end 72 of the inwardly extendingprojections 68 camming against theupper surface 24 and eventually theradiused transition surface 30 of thetransfer ring 22. This will cause a temporary distortion of the generally cylindrical shape of theskirt portion 48 as the inwardly extendingprojections 68 ride on the outside of thetransfer ring 22. At the point at which theclosure 12 is fully screwed onto thecontainer 14, the inwardly extendingprojections 68 will become seated within thenotches 32 that are defined within thetransfer ring 22. When this happens,skirt portion 48 will reassume its cylindrical shape, with the elasticity of theskirt portion 48 biasing the inwardly extendingprojections 68 to remain seated within thenotches 32. If an effort is made by the consumer or a potential wrongdoer to unscrew theclosure 12 from thecontainer 14, thelateral engagement surface 70 of the inwardly extendingprojections 68 will engage thesecond side surface 36 of thenotch 32, thereby impeding or preventing unscrewing of theclosure 12 from thecontainer 14. - A
container assembly 78 that is constructed according to a second embodiment of the invention is depicted inFIGS. 5-7 . Acontainer 74 according to the second embodiment of the invention is identical to the container described above with reference to the first embodiment of the invention, except that thetransfer ring 76 has no notch or other irregularity defined therein. Referring toFIG. 6 , aclosure 79 according to the second embodiment of the invention is identical to the closure described above with reference to the first embodiment except with regard to the retention structure for engaging with the container in such a manner to frustrate efforts that may be made to unscrew the closure from the container. - Closure 79 includes retention structure 80 that is constructed and arranged to engage the
lower surface 26 or the underside of thetransfer ring 76. In the illustrated embodiment, retention structure 80 is embodied as a plurality oflug members 82, each of which extends inwardly from theinner surface 62 of the downwardly dependingskirt portion 48 of theclosure 79. Thelug members 82 are constructed and arranged to slip over the generallyannular transfer ring 76 when theclosure 79 is being screwed onto to thecontainer 74 at the packaging facility. In the illustrated embodiment, a plurality oflug members 82 are utilized. It should be understood, however, that fewer or more lug members could be used according to the invention, including one lid member that would effectively be an annular ring about the inner periphery of theskirt portion 48 of theclosure 79. - It is to be understood, however, that even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
