DETAILED DESCRIPTION

(26) Referring to FIGS. 1A and 1B, respectively, isometric and exploded views of a first embodiment of a lockable programmable container 100 are shown. In some embodiments, the lockable programmable container 100 may include a first element 20, a plurality of rotatable rings 30, and a second element 40. Preferably, the first element 20 includes multiple portions, e.g., a retainer 21 and a cylindrical member 26. Advantageously, for this first embodiment, the multi-piece (i.e., two-piece) first element 20 may be structured and arranged to be used as the cap of the container 100. While any number of rotatable rings 30 may be used, two rings 30 are shown in the figures and are preferred. For the first embodiment, the rotatable rings 30 are operatively disposed on the cap portion of the container 100; for the second embodiment, discussed below, the rotatable rings 30 are operatively disposed on the canister portion of the container 100.

(27) As shown in FIG. 1B, the rotatable rings 30 are annular, having an inner surface 36 and an outer surface 37. In some implementations, a plurality of removable tabs 38 may be formed on the inner surface 36 of each ring 30, while an alphanumeric character 39 may be located on the outer surface 37 of each ring 30. The alphanumerical characters 39 enable the consumer, pharmacist, or authorized third party to create a multi-digit (e.g., a two-digit) combination code for the purpose of locking and selectively unlocking the container 100 (by re-entering the appropriate combination code). Preferably, the size and location of each alphanumerical character 39 on the outer surface 37 of the ring 30 corresponds to a discrete removable tab 38 formed on the inner surface 36 of the ring 30. The inner diameter of the ring 30 may be designed so that, once the rings 30 are placed on the cylindrical member 26, the rings 30, and especially the removable tabs 38 on the inner surface 36, will rotate smoothly about the circumference of the cylindrical member 26. Removal of the tabs 38 and creation of a combination code are discussed below.

(28) FIGS. 2-4B show an illustrative first element 20 that functions as the cap of a container 100 in accordance with the first embodiment of the present invention. According to the first embodiment, the first element 20 includes a retainer 21 and a cylindrical member 26. Preferably the height of the retainer 21 is the same, substantially the same, or less than the height of the cylindrical member 26. The retainer 21 may be manufactured (e.g., by extrusion, molding, 3D-printing, casting, and the like) from, for example, plastic, metal, composites, or other materials while the cylindrical member 26 may be manufactured (e.g., by extrusion, molding, 3D-printing, casting, of the like) from, for example, plastic, metal, composites, or other materials. In some implementations, the retainer 21 may be fixedly attached to the cylindrical member 26 adhesively, by ultrasonic welding, by solvent bonding, and the like.

(29) In some applications, the retainer 21 includes a fully closed first end 22 and an open second end 24 created by a (e.g., annular) sidewall 23 extending perpendicularly or substantially perpendicularly from the closed first end 22. Alignment indicia (e.g., an arrow, a line, a triangle, and the like) may be formed on the sidewall 23 and/or on the closed first end 22 for the purpose of aligning the first element 20 with the second element 40 to lock/unlock the canister 100. In some variations, a flange 25 may be formed on the sidewall 23 about the open second end 24. Advantageously, the flange 25 may be provided to retain the rotatable rings 30 on the cylindrical member 26.

(30) In some embodiments, the cylindrical member 26 includes an annular sidewall 28 having a first opening 27 (e.g., at a distal end thereof) and a second opening 29 (e.g., at an opposing, proximal end thereof). Advantageously, in some applications, the cylindrical member 26 may be configured to provide a uniform diameter between the openings 27, 29. For some applications, however, the annular sidewall may be slightly tapered towards the first opening 27. Because the diameter of the cylindrical member 26 is configured to be uniform (rather than to taper), the shrink rate of a flange during manufacture may become inconsequential.

(31) In some variations, a flange 31 may be formed on the sidewall 28 about OR PROXIMATE the second opening 29. Advantageously, the flange 31 may be provided to retain the rotatable rings 30 on the cylindrical member 26. In some embodiments, breaks 34 may be provided in the flange 25, so that the flange 25 is discontinuous. In some variations, the breaks 34 in the flange 25 are configured to be mateable with corresponding protrusions, projections, ribs 48, and the like formed in the second element 40.

(32) A first notch 32 and a second notch 33 may be formed in the sidewall 28 of the cylindrical member 26, such that the notches 32, 33 are configured to extend (e.g., in an axial or longitudinal direction) from the first opening 27 towards the second opening 29. Although FIG. 3 shows two first notches 32, 33, that is done for the purpose of illustration rather than limitation. More or fewer notches may be formed in the sidewall 28 of the cylindrical member 26. Moreover, although the first notch 32 and the second notch 33 shown in FIG. 3 appear to be diametrically opposed to one another about the sidewall 28 of the cylindrical member 26, that is also done for the purpose of illustration rather than limitation. The first notch 32 and the second notch 33 may be formed on the sidewall 28 of the cylindrical member 26 anywhere about the first opening 27.

(33) In some variations, the first notch 32 and second notch 33 are structured and arranged to be mateable with corresponding projections, protrusions, or the like formed on the inner surface of the sidewall 23 of the retainer 21 and may provide points for fixedly joining (e.g., adhesively, by ultrasonic welding, by solvent bonding, and the like) the retainer 21 and the cylindrical member 26.

(34) In some implementations, an unlocking opening 35 may also be formed in the sidewall 28 of the cylindrical member 26. The unlocking opening 35 is structured and arranged to provide a window or channel in the cylindrical member 26 that is adapted to accommodate a plurality of projections 44, 45 formed on the second element 40. The interaction between the projections 44, 45 and the removable tabs 38 located on the inner surface 36 of the rotatable rings 30 may be used to securely lock the first element 20 and the second element 40. Preferably, the unlocking opening 35 is structured and arranged to extend (e.g., in a longitudinal or axial direction) from the second opening 29, through the flange 31, towards the first opening 27, terminating at a location close to, near, or proximate the first opening 27. More preferably, the unlocking opening 35 extends from the second opening 29, through the flange 31, to a location in the sidewall 28 that just permits the consumer, pharmacist, or other authorized third party to access (as is described in greater detail below) the corresponding tabs 38, so as to allow the consumer, pharmacist, or other authorized third party to remove the tabs 38 corresponding to the combination code from the inner surfaces 36 of the rotatable rings 30. As shown in FIG. 3B, the unlocking opening 35 may also be configured to be proximate one of the notches 32. However, this is done for the purpose of illustration only. Indeed, the unlocking opening 35 may be formed anywhere in the sidewall 28 of the cylindrical member 26.

(35) In some variations, the unlocking opening 35 may be structured and arranged so as to align with the alignment indicia disposed on the sidewall 23 or on the closed first end 22 of the retainer 21. The unlocking opening 35 may also be designed to provide a constant thickness (i.e., width) and a constant height (i.e., length).

(36) Referring to FIG. 5, an illustrative embodiment of a second element 40 for use with a first element 20 and rotatable rings 30 in connection with a locking container 100 is shown. Although the embodied second element 40 is shown as having a cylindrical shape, that is done for illustrative purposes only. In any of its various implementations, portions of the second element 40 may take on any practical structural or aesthetic shape. In some embodiments, the second element 40 includes an open first end 41, a sidewall 42, and a completely closed second end 43 to provide a hollow canister that provides a plenum 49 for storage of the contents of the container 100.

(37) In some applications, the sidewall 42 may include an upper (e.g., cylindrical) portion 42a and a lower portion 42b. Preferably, the outer diameter of the upper portion 42a of the sidewall 42 is designed to be slightly less than the inner diameter of the second opening 29 of the cylindrical member 26 of the first element 20, so that the second element 40, and more specifically, the upper portion 42a of the sidewall 42 of the second element 40 may slide or slip, without excessive frictional resistance, within the second opening 29 of the cylindrical member 26 of the first element 20. Although the lower portion 42b may also be cylindrical in shape, it does not have to be.

(38) In some variations, a plurality of projections 44, 45 may be formed on the upper portion 42a of the sidewall 42, so as to project therefrom. The number of projections 44, 45 may correspond to the number of rotatable rings 30; hence, for the two-ring container 100 shown in FIG. 1A, the total number of projections 44, 45 is two. In some embodiments, the projections 44, 45 are cubical or substantially cubical, C-shaped (as shown), I-shaped, or a combination thereof.

(39) Optionally, to prevent unauthorized personnel from looking between the first element 20 and the second element to observe when empty tab spaces on the rotatable rings 30 are aligned within the unlocking opening 35, a belled portion 46 may be formed to project out from the sidewall 42 of the second element 40, e.g., at a short distance below the final projection 45. The belled portion 46 may, in some variations, provide a delineation between the upper portion 42a and the lower portion 42b of the sidewall 42 of the second element 40. In some applications, a plurality of protrusions, projections, ribs 48, and the like may be formed within the belled portion 46 for the purpose of mating with corresponding breaks 34 in the flange 31 of the cylindrical member 26 of the first element 20.

(40) The belled portion 46 may serve as or provide a blocking function to prevent unauthorized personnel from looking between the first element 20 and the second element 40 to try to align the open or empty spaces, corresponding to where tabs 38 have been removed, on the inner surface 36 of the rotatable rings 30 within the unlocking opening 35. As an alternative to a belled portion, if the shape and size of the lower portion 42b of the sidewall 42 is much greater than that of the upper portion 42a, then the lower portion 42b may provide the blocking function to prevent unauthorized personnel from looking between the first element 20 and the second element 40 to try to align the open or empty spaces in the rotatable rings 30 within the unlocking opening 35. Alternatively, an additional projection (e.g., a blocker) may be formed on the upper portion 42a of the sidewall 42 of the second element 40.

(41) In normal operation, some portion of the projections 44, 45 formed on the upper portion 42a of the second element 40 may be provided to (e.g., structurally) engage (i.e., interfere with) tabs 38 disposed on the inner surface 36 of the rotatable rings 30 to securely lock the first element 20 to the second element 40 until the appropriate combination code has been dialed up (e.g., entered) on the rotatable rings 30. Once the appropriate combination code has been dialed up (e.g., entered) on the rotatable rings 30, the open or empty spaces provided by the tabs removed when establishing the combination code should be properly aligned within the unlocking opening 35, so that the cylindrical member 26 of the first element 20 may be removed from about the upper portion 42a of the sidewall 42 of the second element 40.

(42) In some implementations, alignment indicia 47 (e.g., an arrow, a triangle, a line, and the like) may also be formed on the lower portion 42b of the sidewall 42 of the second element 40 and/or on the belled portion 46. In some embodiments, the alignment indicia 47 aligns with and points towards the projections 44, 45 formed in the upper portion 42a of the second element 40. In some variations, once the upper portion 42a of the sidewall 42 of the second element 40 is inserted into the second opening 29 of the cylindrical member 26 of the first element 20, such that the projections 44, 45 and the unlocking opening 35 are aligned for either locking or unlocking the container 100, the alignment indicia formed on the closed first end 22 and/or formed on the sidewall 23 of the retainer 21 of the first element 20 and the alignment indicia 47 formed on the sidewall 42 and/or on the belled portion 46 of the second element 40 may themselves be aligned. Scrambling or rotating the rings 30 from this alignment position securely locks the container 100, preventing unauthorized personnel from accessing the contents of the container 100. In order to unlock the container 100 to access the contents, the consumer or authorized user may merely rotate the rings 30 to dial up (e.g., enter) the appropriate combination code between the alignment indicia formed on the retainer 21 of the first element 20 and alignment indicia 47 formed on the sidewall 42 and/or on the belled portion 46 of the second element 40.

(43) Referring to FIGS. 6A and 6B, respectively, isometric and exploded views of a second embodiment of a locking programmable container 100′ are shown. In the second embodiment, the locking programmable container 100′ may include a first element 50, a plurality of rotatable rings 60, and a second element 70. Preferably, the first element 50 may include a cylindrical member 56 and a retainer 51. Advantageously, for this second embodiment, the multi-piece (i.e., two-piece) first element 50 may be structured and arranged to be used as the canister of the container 100′. While any number of rotatable rings 60 may be used, two rings 60 are shown in the figures and are preferred. In this variation, the rotatable rings 60 may be adapted for use on the canister portion of the container 100′.

(44) As shown in FIG. 6B, the rotatable rings 60 may be annular, having an inner surface 66 and an outer surface 67. In some implementations, a plurality of removable tabs 68 may be formed on the inner surface 66 of each ring 60, while an alphanumeric character 69 may be located on the outer surface 67 of each ring 60. The alphanumerical characters 69 enable the consumer, pharmacist, or authorized third party to create a multi-digit (e.g., a two-digit) combination code for the purpose of locking and selectively unlocking the container 100′ (by re-entering the appropriate combination code). Preferably, the size and location of each alphanumerical character 69 on the outer surface 67 of the ring 60 corresponds to the size and location of a discrete tab 68 formed on the inner surface 66 of the ring 60. The inner diameter of the ring 60 may be designed or selected so that, once the rings 60 are placed on the cylindrical member 56 of the first element 50, the rings 60, and especially the removable tabs 68 on the inner surface 66 of each ring 60, will rotate smoothly about the circumferential surface or periphery of the cylindrical member 56 of the first element 50.

(45) FIGS. 7 and 8 show, respectively, isometric and exploded views of an illustrative first element 50 that functions as the canister of a container 100′ in accordance with the second embodiment of the present invention. According to the second embodiment, the first element 50 may include a retainer 51 and a cylindrical member 56. The height of the retainer 51 may be the same, substantially the same, or greater than the height of the cylindrical member 56. The retainer 51 may be manufactured (e.g., by extrusion, molding, 3D-printing, casting, and the like) from, for example, plastic, metals, composites, and the like, while the cylindrical member 56 may be manufactured (e.g., by extrusion, molding, 3D-printing, casting, and the like) from, for example, plastic, metals, composites, and the like. In some implementations, the retainer 51 may be fixedly attached to the cylindrical member 56 adhesively, by ultrasonic welding, by solvent bonding, and the like. Optionally, a plurality of notches, such as the notches shown in connection with the cylindrical member 26 (e.g., shown in FIG. 3) may also be provided on the cylindrical member 56.

(46) In some applications, the retainer 51 may include a fully closed first end 52 and an open second end 54. A (e.g., annular) sidewall 53 may extend perpendicularly or substantially perpendicularly from the closed first end 52 towards the open second end 54. The hollow portion of the retainer 51 created by the sidewall 53 may provide a plenum 49′ for storage of the contents of the container 100′. Although the embodied retainer 51 is shown as having a cylindrical or substantially cylindrical shape, that is done for illustrative purposes only. In any of its various implementations, portions of the retainer 51 may take on any practical structural or aesthetic shape.

(47) In some implementations, a belled portion 62, having a projecting sidewall 63 that projects out and away from the sidewall 53 of the retainer 51, may be formed to project out from the sidewall 53 of the first element 50, e.g., at, close to, near, or proximate the open second end 54 of the retainer 51. The belled portion 62 may serve as or provide a blocking function to prevent unauthorized personnel from looking between the first element 50 and the second element 70 to try to align the open or empty spaces, corresponding to where tabs 38 have been removed, on the inner surface 66 of the rotatable rings 60 within the unlocking opening 55. As an alternative to a belled portion 62, if the shape and size of the sidewall 53 are large enough, the sidewall shape may serve as or provide the blocking function. Alignment indicia 64 (e.g., an arrow, a line, a triangle, and the like) may be formed on the sidewall 53 and/or on the belled portion 62 for the purpose of aligning the first element 50 with the second element 70 to lock and selectively unlock the container 100′.

(48) As shown in FIG. 6B, in some embodiments, the cylindrical member 56 may include an annular sidewall 58 having a first opening 57 (e.g., at a distal end thereof) and a second opening 59 (e.g., at an opposing, proximal end thereof). A flange 61 may be formed on the sidewall 58. In some variations, the flange 61 may be formed midway or approximately midway between the first opening 57 and the second opening 59. Advantageously, the flange 61 may be provided to retain the rotatable rings 60 on the cylindrical member 56 and to prevent the second element 70 from interfering with rotation of the rings 60. An unlocking opening 55 may be structured and arranged to bisect the cylindrical member 56, extending (e.g., in a longitudinal or axial direction) from the second opening 59, through the flange 61, to the first opening 57 of the cylindrical member 56. The width of the unlocking opening 55 may be designed or selected to be slightly larger than the circumferential dimension of projections 74, 75 formed on the second element 70 and used to lock the first element 50 and the second element 70, so that, when an appropriate combination code has been dialed up (e.g., entered) on the rotatable rings 60, the projections 74, 75 may slide unhindered into the unlocking opening 55 of the cylindrical member 56. The width of the unlocking opening 55 may have a constant dimension; alternatively, the width of the unlocking opening 55 may taper slightly towards the first opening 57.

(49) Alternatively, as shown in FIG. 6C, in some embodiments, the cylindrical member 56′ may include an annular sidewall 58 having a first opening 57 (e.g., at a distal end thereof) and a second opening 59 (e.g., at an opposing, proximal end thereof). A flange 61′ may be formed on the sidewall 58 at, near, or proximate the second opening 59 of the cylindrical member 56′. Advantageously, the flange 61′ may be provided to retain the rotatable rings 60 on the cylindrical member 56 and also to prevent the second element 70 from interfering with the rotation of the rings 60. An unlocking opening 55′ may be structured and arranged to extend (e.g., in a longitudinal or axial direction) from the second opening 59, through the flange 61′, to the first opening 57 of the cylindrical member 56′. The width of the unlocking opening 55′ may be designed or selected to be slightly larger than the circumferential dimension of projections 74, 75 formed on the second element 70 and used to lock the first element 50 and the second element 70, so that, when an appropriate combination code has been dialed up (e.g., entered) on the rotatable rings 60, the projections 74, 75 may slide unhindered into the unlocking opening 55′ of the cylindrical member 56′. The width of the unlocking opening 55′ may have a constant dimension; alternatively, the width of the unlocking opening 55′ may taper slightly towards the first opening 57. Although the unlocking opening 55′ may also be adapted to bisect the sidewall 58 of the cylindrical member 56′, as shown in FIG. 6C, the length of the unlocking opening 55′ may only extend up some portion of the height of the sidewall 58.

(50) Referring to FIG. 9, an illustrative embodiment of a second element 70 for use with a first element 50 and rotatable rings 60 in connection with a locking programmable container 100′ is shown. Although the embodied second element 70 is shown as having an annular shape, this is done for illustrative purposes only. Optionally, the second element 70 may have a belled or mushroom shape. The second element 70, which in the second embodiment may function as a cap to the canister of the container 100′ may take on any practical structural or aesthetic shape. Advantageously, the annular, belled, and mushroom shapes may serve a blocking function to prevent unauthorized personnel from observing the location where the tabs to the combination code have removed.

(51) In some embodiments, the second element 70 may include an open first end 71, a (e.g., cylindrical) sidewall 72, and a top portion 73 that includes a completely closed second end 76. Preferably, the outer diameter of the sidewall 72 may be designed to be slightly less than the inner diameter of the second opening 59 of the cylindrical member 56, 56′ of the first element 50, so that the second element 70 may slip or slide, without excessive frictional resistance, within the second opening 59 of the cylindrical member 56, 56′ of the first element 50.

(52) In some variations, a plurality of projections 74, 75 may be formed on the sidewall 72 of the second element 70. Preferably, the number of projections 74, 75 may correspond to the number of rotatable rings 60 retained on the cylindrical member 56, 56′; hence, for the two-ring container 100′ shown in FIGS. 6A and 6B, the total number of projections 74, 75 is two. In some embodiments, the projections 74, 75 may be cubical or substantially cubical in shape. In other embodiments, the projections 74, 75 may be C-shaped (as shown), I-shaped, or a combination thereof. Because the top portion 73 of the second element 70 is annular, belled, or mushroom-shaped, an additional (e.g., blocker) protrusion may not be not necessary, as the top portion 73 may be designed to extend sufficiently beyond the outer surface of the sidewall 72 to cover the second opening 59 and unlocking opening 55, 55′ of the cylindrical member 56, 56′ of the first element 50. An optional additional (e.g., blocker) protrusion, however, may be formed on the outer surface of the sidewall 72 for that purpose.

(53) A portion of the projections 74, 75 may be provided to (e.g., structurally) engage tabs 68 disposed on the inner surface 66 of the rotatable rings 60 to securely lock the first element 50 to the second element 70 until the appropriate combination code has been dialed up (e.g., entered) on the rotatable rings 60. Once the appropriate combination code has been dialed up (e.g., entered) on the rotatable rings 60, the open or empty spaces resulting after the corresponding tabs 68 were removed should be properly aligned at the unlocking opening 55, 55′, so that the cylindrical sidewall 72 and the second element 70 may be slidingly removed from within the second opening 59 of the cylindrical member 56, 56′ of the first element 50.

(54) Alignment indicia 77 (e.g., an arrow, a triangle, a line, and the like) may also be formed on the top portion 73 of the second element 40. In some variations, once the sidewall 72 of the second element 70 is (e.g., slidingly) inserted into the second opening 59 of the cylindrical member 56, 56′ of the first element 50, such that the projections 74, 75 and the unlocking opening 55, 55′ are aligned for either locking or unlocking the container 100′, the alignment indicia 78 on the sidewall 53 of the retainer 51 of the first element 50 and the alignment indicia 77 on the top portion 73 of the second element 70 may themselves be aligned. Scrambling or rotating the rings 60 from this alignment position should result in securely locking the container 100′, preventing unauthorized personnel from accessing the contents of the container 100′. In order to unlock the container 100′ to access the contents, the consumer, pharmacist, or authorized third party may merely rotate the rings 60 to dial up the appropriate combination code between the alignment indicia 77, 78 on the retainer 51 of the first element 50 and the top portion 73 of the second element 70.

(55) Referring to FIGS. 10A and 10B, isometric and exploded views of a third embodiment of a locking programmable container 100″, respectively, are shown. In some embodiments, the locking programmable container 100″ may include a first element 80, a plurality of rotatable rings 90, and a second element 110. While any number of rotatable rings 90 may be used, two rings 90 are shown in the figures and are preferred. In this variation, the rotatable rings 90 may be adapted for use on the canister portion of the container 100″.

(56) As shown in FIG. 10B, the rotatable rings 90 may be annular, having an inner surface 91 and an outer surface 92. In some implementations, a plurality of removable tabs 93 may be formed on the inner surface 91 of each ring 90, while an alphanumeric character 94 may be located on the outer surface 92 of each ring 90. The alphanumerical characters 94 enable the consumer, pharmacist, or authorized third party to create a multi-digit (e.g., a two-digit) combination code for the purpose of locking and selectively unlocking the container 100″ (by re-entering the appropriate combination code). Preferably, the size and location of each alphanumerical character 94 on the outer surface 92 of the ring correspond to the size and location of a discrete tab 93 formed on the inner surface 91 of the ring 90. The inner diameter of each ring 90 may be designed or selected so that, once the rings 90 are placed on an upper sidewall portion 114 of the canister portion 110, the rings 90, and especially the tabs 93 on the inner surface 91 of the rings 90, will rotate smoothly about the circumferential surface or periphery of the upper sidewall portion 114. In some applications, a plurality of protrusions 117 formed on and about the upper sidewall portion 114 of the canister element 110 may be used to retain the rings 90 on the upper sidewall portion 114. Alternatively, a flange may be formed on the upper sidewall portion 114 to retain the rings 90 thereon.

(57) FIGS. 11 and 12 show an illustrative cap element 80 that functions as the cap of a container 100″ in accordance with the third embodiment of the present invention. According to the embodiment, the cap element 80 may include a retainer 89 (FIG. 11) and a cylindrical member 81 (FIG. 12). Preferably the height of the retainer 89 may be configured to have the same, substantially the same, or less than the height of the cylindrical member 81. The retainer 89 may be manufactured (e.g., by extrusion, molding, 3D-printing, casting, and the like) from, for example, plastic, metals, composites, and the like, while the cylindrical member 81 may be manufactured (e.g., by extrusion, molding, 3D-printing, casting, and the like) from, for example, plastic, metals, composites, and the like. In some implementations, the retainer 89 may be fixedly attached to the cylindrical member 81 adhesively, by ultrasonic welding, by solvent bonding, and the like.

(58) In some applications, the retainer 89 may include a fully closed first end 95 and an open second end 96. A (e.g., annular) sidewall 97 may extend perpendicularly or substantially perpendicularly from the closed first end 95 to the open second end 96. Although the embodied retainer 89 is shown as having a cylindrical or substantially cylindrical shape, that is done for illustrative purposes only. In any of its various implementations, portions of the retainer 89 may take on any practical structural or aesthetic shape.

(59) Alignment indicia 98 (e.g., an arrow, a line, a triangle, and the like) may be formed on the sidewall 97 for the purpose of aligning the cap element 80 with the canister element 110 to lock and selectively unlock the container 100″. In some variations, a flange 99 may be formed on the sidewall 97 of the cap portion 89, e.g., at, near, close to, or proximate and/or about the open second end 96.

(60) As shown in FIG. 12, in some embodiments, the cylindrical member 81 of the cap element 80 may include an annular sidewall 84 having a first opening 83 (e.g., at a distal end thereof) and a second opening 82 (e.g., at an opposing, proximal end thereof. Multiple notches 87, 88 may be formed in the sidewall 84 at the first opening 83, for example, for the purpose of fixedly attaching the retainer 89 to the cylindrical member 81. Although FIG. 12 shows a first notch 87 and a second notch 88, that is done for the purpose of illustration rather than limitation. More or fewer notches may be formed in the sidewall 84 of the cylindrical member 81. Moreover, although the first notch 87 and the second notch 88 shown in FIG. 12 appear to be diametrically opposed to one another, that is also done for the purpose of illustration rather than limitation. The first 87 and the second notch 88 may be formed on the sidewall 84 anywhere about the first opening 83. In some variations, the first notch 87 and second notch 88 may be mateable with corresponding projections, protrusions, or the like formed on the inner surface of the sidewall 97 of the retainer 89 and may provide points of connection between the retainer 89 and the cylindrical member 81.

(61) In some variations, a plurality of projections 85, 86 may be formed on the sidewall 84 of the cylindrical member 81 of the cap element 80. In some embodiments, the projections 85, 86 may be cubical or substantially cubical in shape, C-shaped (as shown), I-shaped, or a combination thereof. Preferably, the number of projections 85, 86 may correspond to the number of rotatable rings 90 disposed or disposable on the canister element 110; hence, for the two-ring container 100″ shown in FIGS. 10A and 10B, the total number of projections 85, 86 is two. In some variations, however, an additional (e.g., blocker) protrusion may be formed on the sidewall 84 of the cylindrical member 81 to block the combination code from visual discovery. Because the retainer 89 of the cap element 80 includes a flange 99 that projects sufficiently from the sidewall 97, a blocker protrusion is not necessary, as the flange 99 may extend sufficiently beyond the outer peripheral surface of the sidewall 84 of the cylindrical member 81 to cover an unlocking opening 118 formed in the canister element 110.

(62) A portion of the projections 85, 86 may be provided to (e.g., structurally) engage tabs 93 located on the inner surface 91 of the rotatable rings 90 to securely lock the cap element 80 to the canister element 110 until the appropriate combination code has been dialed up (e.g., entered) on the rotatable rings 90. Once the appropriate combination code has been dialed up (e.g., entered) on the rotatable rings 90, the open or empty spaces provided after the corresponding tabs were removed should be properly aligned at the unlocking opening 118, so that the cylindrical member 81 of the cap element 80 may be slidingly removed from within the unlocking opening 118 of the canister element 110.

(63) Referring to FIG. 13, an illustrative embodiment of a canister element 110 for use with the cap element 80 and rotatable rings 90 in connection with a locking programmable container 100″ is shown. In some embodiments, the canister element 110 may include an open first end 111, an upper sidewall portion 114, a lower sidewall portion 113, and a completely closed second end 112. The canister element 110, which in the third embodiment may function as a canister for the container 100″, may take on any practical structural or aesthetic shape. For example, as shown, in some applications, the canister element 110 may have a cylindrical or substantially cylindrical shape that, on the exterior surface of the sidewall 113, 114, is broken up by a projecting or belled portion 115. The projecting or belled portion 115 formed on the canister element 110 may serve as or provide a blocking function to prevent unauthorized personnel from visually aligning the open or empty spaces resulting from removed tabs at or within the unlocking opening 118 to unlock the lockable container 100″.

(64) In some implementations, the upper sidewall portion 114 may be designed to provide a surface having a constant circumferential dimension for holding the rotatable rings 90. In some variations, however, the circumferential dimension may taper slightly towards the first open end 111 of the canister element 110. In order to retain the rotatable rings 90 on the upper sidewall portion 114, a plurality of (e.g., four) protrusions 117 may be formed in the upper sidewall portion 114. In placing the rings 90 on the canister element 110, force applied to the inner surface 91 of the rings 90 may force the protrusions 117 to displace radially towards the plenum of the canister element 110. Once the ring 90 has passed over the protrusions 117, the protrusions 117 may return to their original locations. Preferably, the inner diameter of the upper sidewall portion 114 may be designed or selected to be slightly greater than the outer diameter of the second opening 82 of the cylindrical member 81 of the cap element 80, so that the cap element 80 may slide, without excessive frictional resistance, within the first opening 111 of the canister element 110.

(65) In order to set a combination code and, subsequently, to lock and selectively unlock the cap element 80 and the canister element 110, an unlocking opening 118 may be formed in the upper sidewall portion 114 of the canister element 110. Preferably, the unlocking opening 118 may be structured and arranged to extend (e.g., in a longitudinal or axial direction) from the first opening 111 towards the lower sidewall portion 113. More preferably, the unlocking opening 118 may be structured and arranged to extend from the first opening 111 to a location in the upper sidewall portion 114 that just permits the consumer, pharmacist, or other authorized third party to access (as is described in greater detail below) the corresponding tabs 93, so as to allow the consumer, pharmacist, or other authorized third party to remove the tabs 93 corresponding to the combination code from the inner surfaces 91 of the rotatable rings 90. The width of the unlocking opening 118 should be designed to be slightly larger than the circumferential dimension of the projections 85, 86 used to lock the cap element 80 and the canister element 110, so that, when an appropriate combination code has been dialed up (e.g., entered) on the rotatable rings 90, projections 85, 86 formed on the cap element 80 may slide unhindered into the first opening 111 of the canister element 110.

(66) Alignment indicia 116 (e.g., an arrow, a triangle, a line, and the like) may also be formed, for example, on the lower sidewall portion 113 and/or the belled portion 115 of the canister element 110, so as to align with the unlocking opening 118. In some variations, once the cylindrical member 81 of the cap element 80 is inserted into the first opening 111 of the canister element 110, such that the projections 85, 86 and the unlocking opening 118 are aligned for either locking or unlocking the container 100″, the alignment indicia 98 on the sidewall 97 of the retainer 89 of the cap element 80 and the alignment indicia 116 on the canister element 110 may themselves be aligned. Scrambling or rotating the rings 90 from this alignment position should result in securely locking the container 100″, preventing unauthorized personnel from accessing the contents of the container 100″. In order to unlock the container 100″ to access the contents, the consumer, pharmacist, or authorized third party may merely rotate the rings 90 to dial up the appropriate combination code between the alignment indicia 98 on the retainer 89 of the cap element 80 and the alignment indicia 116 on the canister element 110.

(67) Costs associated with the shipment of lightweight canisters and containers may far exceed the costs of manufacturing, increasing the total cost of the canisters and containers. Advantageously, as shown in FIGS. 18A and 18B, in some embodiments, multiple canisters 140a, 140b, 140c may be stacked, one inside the other, to minimize the overall volume to be shipped. In some variations, bottom portions of each of the canisters 140a, 140b, 140c may be tapered 120a, 120b, 120c, so that the tapered portion 120a of a first canister 140a is able to be slidingly inserted through a first opening 141b of a second canister 140b, while the tapered portion 120b of the second canister 140b is able to be slidingly inserted through a first opening 141c of a third canister 140c, and so forth. Although only three canisters 140a, 140b, 140c are shown in FIGS. 18A and 18B, this is done for the purpose of illustration rather than limitation. In some variations, the tapered portions 120a, 120b, 120c of the canisters 140a, 140b, 140c may be tapered at an angle less than about ten (10) degrees, e.g., between about five (5) degrees and about ten (10) degrees. In other variations, the tapered portions 120a, 120b, 120c of the canisters 140a, 140b, 140c may be tapered at an angle greater than about ten (10) degrees.

(68) Having described various embodiments of a locking programmable container, a method of establishing a combination code and of opening and/or securing a first element to a second element of a locking container will be described. In order to lock and unlock the container, a combination code must be dialed in (e.g., entered) on the rotatable rings, such that the alphanumerical characters, on the plurality of rings and that make up the combination code, are aligned within an alignment axis defined by alignment indicia formed on the first element and alignment indicia formed on the second element and, moreover, the alphanumerical characters are aligned with an unlocking opening formed, for example, in the cylindrical member of the first element.

(69) Recall that each ring may include a plurality of alphanumerical characters on its outer surface and a corresponding plurality of removable tabs on its inner surface. Thus, a discrete tab on the inner surface of the ring may correspond to a discrete alphanumerical character on the outer surface of the ring. The interaction between or engagement of the tabs on the inner surface of the rotatable rings, which are disposed on the first element, and a plurality of projections, which are disposed on the second element, provide the locking mechanism that secures the first element to the second element. In short, the rings, tabs, and projections, in combination, may create a programmable locking container that requires a combination code to secure and to selectively open the container. Advantageously, if R represents the number of rings and n represents the number of alphanumerical characters (and hence the number of tabs) on each ring, then the number of possible combination codes (C) for the locking container may be determined by the equation:
C=R.sup.n.

(70) Thus, for two rings (i.e., n=2) and ten alphanumerical characters (i.e., R=10) per ring, there would be 100 possible combination codes (C). Increasing the number of rings (R) and/or increasing the number of alphanumerical characters (n) provide a greater number of possible combination codes.

(71) Once the tabs corresponding to the digits of the combination code have been removed from the inner surfaces of each rotatable ring, the void, empty space, or opening left in place of the removed tab is not able to interact with the projections. As a result, when the alphanumerical characters corresponding to the tab openings are aligned between the alignment indicia on the first element and the alignment indicia on the second element, the void or empty tab openings is no longer present to obstruct movement of the projections as the second element is slidingly removed from inside of the cylindrical member of the first element.

(72) The selective removal of tabs and the creation of a combination code can be performed at the time of manufacture (e.g., by the manufacturer) or, alternatively, the combination code may be created by the consumer, the pharmacist, or some other authorized third party. The creation process requires, first, determining what the combination code will be and then, with the first element removed from the second element, dialing in (i.e., entering) the appropriate combination code of the rings, such that the combination code is aligned with the alignment indicia on the retainer of the first element.

(73) Aligning the combination code within the alignment position defined by the alignment indicia on the retainer of the first element and the alignment indicia on the second element ensures that the corresponding tabs for the combination code are aligned and exposed within the unlocking opening on the cylindrical member of the first element. The exposed tabs may then be removed, e.g., using a sharp instrument (e.g., a penknife, a safety razor blade, an X-ACTO® knife, nail clippers, and the like).

(74) Alternatively, the consumer, pharmacist, authorized third party, and the like may use an encoder 200 to set the combination code for a locking container 100. Referring to FIGS. 14 and 15, an illustrative first embodiment of an encoding device or encoder 200 for programming a combination code in the rotatable rings disposed on the first element of a locking container is shown. In some embodiments, the encoder 200 may include a base portion 210 and a plunger portion 220. In some implementations, the base portion 210 of the encoder 200 may be configured to include a base element 201 (e.g., to provide support and stability) to which a post portion 202 is fixedly attached (e.g., via unitary construction). In some variations, the post portion 202 may be structured and arranged to be a hollow cylinder having a first, closed end at a proximal end thereof (e.g., at the base element 201) and a second, open end 207 at a distal end thereof. In some variations, the post portion 202 may include a plurality of concentric, coaxial hollow cylinders. The second, open end 207, as well as the inner plenum of the hollow cylinder, may be designed and dimensioned to accommodate a biasing element 219 (e.g., a spring) within the inner plenum of the hollow post portion 202.

(75) A pair of retaining projections 203 may be formed on the sidewall of the post portion 202. Preferably, the retaining projections 203 may be configured to be diametrically opposed to one another on the sidewall of the post portion 202. Furthermore, on the sidewall of the post portion 202, for example, equidistant from the retaining projections 203, an upper projection 205 and a lower projection 204 may be formed. In some applications, the upper projection 205 may be structured and arranged to fixedly retain a cutting element 206 for cutting the removable tabs 38. Preferably, the width dimension of the upper projection 205 is designed to pass through the unlocking opening 35 in the cylindrical member 26 of the first element 20 without significant frictional resistance.

(76) To cover the cutting element 206 (e.g., to prevent injury from an otherwise exposed cutting element 206), a cantilevered element 208 may be provided. In some implementations, the cantilevered element 208 may be rotatably attached to the base element 201 near, close to, or proximate where the lower projection 204 joins the base element 201, such that the cantilevered element 208 may flex out and away from the upper projection 205 and the cutting element 206 during the encoding process. In some variations, alignment indicia 209 may be formed at a distal end of the cantilevered element 208 for use in aligning the first element 20 and, more particularly, the unlocking opening 35 on the encoder 200.

(77) In some embodiments, the plunger portion 220 may be configured as a hollow cylinder that includes an open first end 211, a partially closed second end 213, and a sidewall 212 disposed therebetween. Preferably, the inner diameter of the open first end 211 may be designed or selected to be slightly greater than the outer diameter of the post portion 202 of the base portion 210, so that the inner surface of the plunger portion 220 may translate over the outer surface of the post portion 210 without excessive frictional resistance. Optionally, an opening 214 may be formed in the partially closed second end 213. Advantageously, the optional opening 214 promotes a constant wall thickness during plastic injection molding and, also, enables users to view the biasing element 219 disposed within the post portion 202 of the base portion 210 and the plunger portion 220.

(78) To accommodate the upper projection 205 and the lower projection 204, a longitudinal opening 218 may be configured or formed in the sidewall 212 of the plunger portion 220. A plurality (e.g., a pair) of longitudinal openings 215 for receiving the retaining projections 203 on the post portion 202 may also be provided or formed in the plunger portion 220. The openings 215 may be structured and arranged to cooperate with the pair of retaining projections 203 to slidingly connect the plunger portion 210 to the post portion 202 of the base portion 210. Preferably, the openings 215 may be configured to be diametrically opposed to one another on the sidewall 212 of the plunger portion 220. More preferably, the openings 215 may be designed or dimensioned to accommodate the necessary translation of the plunger portion 220 during the encoding process to produce the combination code on the rings 30.

(79) In some applications, in order to properly position the first element 20 on the encoder 200 and/or to properly maintain the position of first element 20 during the encoding process, a plurality of (e.g., longitudinal or axial) ribs 216 may be provided about the sidewall 212 of the plunger portion 220. Advantageously, in some embodiments, the locations of the ribs 216 may be structured and arranged on the sidewall 212 so that the ribs 216 may be mateable with corresponding breaks 34 in the flange 31 of the cylindrical member 26 of the first element 20. Mating of the ribs 216 and the breaks 34 in the flange 31 may minimize the rotation of the first element 20 during the encoding process.

(80) Having described a first embodiment of an encoding device 200, a process for encoding the rings 30 of the canister 100 using the encoding device 200 will now be described. In a first step, encoding the rings 30 disposed on the first element 20 includes dialing up (e.g., entering) the combination code on the alphanumerical characters 39 on the rings 30 disposed on the first element 20. Preferably, the desired combination code is aligned with alignment indicia formed on the first element 20. In a next step, the first element 20 with the desired combination code may be placed over and on the plunger portion 220. Advantageously, the ribs 216 on the plunger portion 220 and the breaks 34 in the flange 31 of the cylindrical member 26 of the first element 20 may facilitate placing and properly aligning the first element 20 on the plunger portion 220. In a next step, the user should ensure that the desired combination code is now properly aligned between the alignment indicia on the retainer 21 of the first element 20 and the alignment indicia 209 on the cantilevered element 208.

(81) Once the user is comfortable with the combination code and its proper alignment on the encoding device 200, the user may apply an axial force to the closed end 22 of the retainer 21 of the first element 20 (e.g., by using the palm of the user's hand), compressing the biasing element 219 and driving the first element 20 and the plunger portion 220 downwards towards the base element 201. In some applications, as the first element 20 is driven downwards, the rings 30 may cause or force the cantilevered element 208 to flex out and away from the cutting element 206, while the upper projection 205 and the cutting element 206 slide into the unlocking opening 35 in the cylindrical member 26 of the first element 20, removing the tabs 38 associated with the alphanumerical characters 39 of the desired combination code.

(82) Once the encoding is completed, the user may remove the load or force applied to the closed end 22 of the retainer 21 of the first element 20, allowing the biasing element 219 to return the plunger portion 220 to its initial (e.g., at rest) position. The first element 20 may then be removed from the plunger portion 220 and inspected to ensure that the tabs 38 associated with the combination code were completed removed from the inner surface 36 of the rings 30. The user may then want to ensure that the locking feature and the combination code work by, first, scrambling the rotating rings 30 and by, then, dialing up (i.e., entering) the appropriate combination code on the rings 30. Once the appropriate combination code is dialed up (e.g., entered), the user may again visually inspect the inner surfaces 36 of the rings 30 through the second opening 29 and the unlocking opening 35 in the cylindrical member 26 of the first element 20 to ensure that the void or empty space left by the removed tabs 38 appears within the unlocking opening 35. The verification process may also be repeated after the first element 20 and second element 40 have been joined and the rings 30 scrambled again.

(83) Referring to FIGS. 16 and 17, a second embodiment of an encoding device or encoder 200′ is shown. In some embodiments, the encoder 200′ may be structured and arranged as a hollow or substantially hollow cylinder having a sidewall 202′ and at least one open end 207′. The opposing end may be opened or closed or a combination of the two. In some applications, a cutting device 210′ may be formed at, near, close to, or proximate an opening 225 in the sidewall 202′ of the encoder 200′. In some variations, the cutting device 210′ may include an upper projection 205′, a lower projection 204′, and a cantilevered element 208′, which may be configured to operate as previously described in connection with the first embodied encoder 200. A cutting element 206′ may be fixedly attached to the upper projection 205′.

(84) Having described a second embodiment of an encoding device 200′, a process for encoding the rings of the container 100 using the encoding device 200′ will now be described. In a first step, encoding the rings 30 disposed on the first element 20 includes dialing up (e.g., entering) the combination code on alphanumerical characters 39 on the rings 30 disposed on the first element 20. Preferably, the desired combination code may be aligned with alignment indicia formed on the first element 20. In a next step, the first element 20 with the desired combination code may be placed over the open end 207′ about the sidewall 202′ of the encoder 200′. In a next step, the user should ensure that the desired combination code is now properly aligned between the alignment indicia on the retainer 21 of the first element 20 and the cantilevered element 208′.

(85) Once the user is comfortable with the combination code and its proper alignment on the encoding device 200′, the user may apply an axial force to the closed end 22 of the retainer 21 of the first element 20 (e.g., by using the palm of the user's hand), driving the first element 20 downwards. In some applications, as the first element 20 is driven downwards, the rings 30 may force or cause the cantilevered element 208′ to flex out and away from the cutting element 206′, while the upper projection 205′ and the cutting element 206′ slide into the unlocking opening 35 in the cylindrical member 26 of the first element 20, removing the tabs 38 associated with alphanumerical characters 39 of the desired combination code.

(86) Once the encoding is completed, the user may remove the first element 20 from the encoder 200′ and inspect it to ensure that the tabs 38 were completed removed from the inner surface 36 of the rings 30. The user may then want to ensure that the locking feature and the combination code work by, first, scrambling the rotating rings 30 and by, then, dialing up (i.e., entering) the appropriate combination code on the rings 30. Once the appropriate combination code is dialed up (e.g., entered), the user may again visually inspect the inner surfaces 36 of the rings 30 through the second opening 29 and the unlocking opening 35 in the cylindrical member 26 of the first element 20 to ensure that the void or empty space left by the removed tabs 38 appears within the unlocking opening 35. The verification process may also be repeated after the first element 20 and second element 40 have be joined and the rings 30 scrambled again.

(87) The invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The foregoing embodiments, therefore, are to be considered in all respects illustrative rather than limiting the invention described herein. Scope of the invention is thus indicated by the appended claims, rather than by the foregoing description, and all changes that come within the meaning and range of equivalency of the claims are intended to be embraced therein.
