(27) In short, a dispensing cap constructed in accordance with one or more aspects of the present invention provides a dispensing cap that is removably securable to a container. In one aspect, the dispensing cap is a two-piece cap, including an inner cover with a flip up lid and an outer ring. The combination and manipulation of the inner cover and the outer ring provide several child resistant features and restraints that prevent access to the contents of a container to which the dispensing cap is affixed. For example, the outer ring assembled to the inner cover is a child resistant feature when removing the dispensing cap from a container. In one embodiment, the inner cover is coaxially retained within the outer ring. The outer ring is rotatable around the inner cover between a locked position and an unlocked position. In the locked position, the lid is prevented from being flipped up. In one example, the outer ring and the inner cover will move together to screw off a container when downward pressure is applied to the outer ring and turned in a counterclockwise direction. This is one aspect rendering the removal of the dispensing cap child resistant. These and other features of a dispensing cap constructed in accordance with one or more aspects of the present invention will be described in more detail below.

(28) Referring now to FIGS. 1A-1C, there is shown various views of a dispensing cap 100 constructed in accordance with one or more aspect of the present invention. Dispensing cap 100 may be removably securable to a container 200, as illustrated in FIG. 2. Container 200 may be, for example, a conventional prescription vial for holding loose content such as pills. In one example, container 200 includes a bottom wall 210 that is substantially perpendicular to a longitudinal axis 202 and cylindrical sidewall 220 extending upwardly from bottom wall 210. Sidewall 220 terminates in an open end 230 and includes neck 240. Neck 240 may include an outer surface 242 having a plurality of threads 244 that mate with inner threads provided on dispensing cap 100 to screw dispensing cap 100 onto container 200. Instead of mating threads, alternative circumferential or annular locking elements such as, for example, locking projections, indentations, push and turn bodynet lugs or any other suitable type of external surface manifestations may be used to removeably retain or secure dispensing cap 100 to container 200. In other embodiments, dispensing cap 100 may be coupled to container 200 in any known and desired removable child resistant manner.

(29) In one embodiment, container 200 may include a safety seal covering the open end 230 after initial filling of container 200 from, for example, the factory. In one aspect, dispensing cap 100 may be sized to accommodate this safety seal under, for example, inner cover 300. The dispensing cap 100 could then be initially removed to break or remove the safety seal for future use.

(30) As illustrated in FIGS. 1A-1C, dispensing cap 100 includes a front portion 110, a back portion 120 diametrically opposed to front portion 110, and diametrically opposed side portions 130. Dispensing cap 100 also includes an inner cover 300 and an outer ring 400. Inner cover 300 is coaxially nested within outer ring 400. As described in more detail below, inner cover 300 and outer ring 400 may be manipulated relative to each other to be in a number of different configurations, including a locked position (see FIG. 1A), an unlocked position (see FIG. 1B) and an open position (see FIG. 1C).

(31) FIGS. 3A-3G illustrate one example of an inner cover 300 constructed in accordance with one or more aspects of the present invention. Inner cover 300 is a dispensing cover that is coupled to container 200 in any suitable manner. For example, inner cover 300 may be screwed to container 200 by mating threads 244, 329, respectively, formed on the outer surface 242 of neck 240 of container 200 and on inner surface 328 of sidewall 322 of inner cover 300 (see e.g. FIGS. 6A and 6B).

(32) In one embodiment, inner cover 300 includes a longitudinal axis 302, a front portion 304, a back portion 306 diametrically opposed to front portion 304, and diametrically opposed side portions 308. Inner cover 300 also includes a base 320 and a lid 370. Lid 370 may be pivotably coupled to base by, for example, a hinge 310. In one example, lid 370 may be a flip-top type of lid to allow dispensing of product out of open end 230 of container 200.

(33) Base 320 of inner cover 300 may include a sidewall 322 and a deck 342. Deck 342 extends radially inward from a top end 324 of sidewall 322 and transversely to longitudinal axis 302. Deck 342 may include a top surface 344 (see e.g. FIG. 3A), a bottom surface 364 (see e.g. FIG. 3G) and a dispensing opening 366 (see e.g. FIG. 3B). In one embodiment, a portion of bottom surface 364 of deck 342 may form a seal with open end 230 of container 200 when secured together.

(34) As illustrated in FIG. 3B, top surface 344 of deck 342 may include a recessed portion 346. In one example, recessed portion 346 may extend from front portion 304 to back portion 306. Deck recessed portion 346 is configured and sized to receive and accommodate lid 370 in a closed position in accordance with one or more aspects of the present invention.

(35) As illustrated in FIG. 3A, top surface 344 of deck 342 may also include two inner semi-circular surfaces 352 and two curved edge surfaces 356. Each inner semi-circular surface 352 may be disposed between a curved edge surface 356 and a flat side 347 of recessed portion 346. Flat sides 354 of two inner semi-circular surfaces 352 border a respective side 376 of lid 370 in a closed position (see e.g. FIG. 3C). Two curved edge surfaces 356 extend radially inwardly from the peripheral of deck 352 on side portions 308 of inner cover 300 and circumferentially from front portion 304 to back portion 306 alongside side portions 308. In one example, inner semi-circular surfaces 352 lie in a different plane transverse to longitudinal axis 302 than two curved edge surfaces 356.

(36) In one embodiment, a plurality of circumferentially spaced ratchet depressions 358 may be formed in curved edge surfaces 356. Each depression 358 may be formed by an inclined surface 360 and a stop surface 362 (see e.g. FIG. 3B). In one example illustrated in FIG. 3B, inclined surface 360 angles inward from curved edge surface 356 in a counterclockwise direction to create a ramp towards stop surface 362. Stop surface 362 extends perpendicularly inward from semi-circular edge surface 356 and substantially transverse to longitudinal axis 302.

(37) Sidewall 322 includes an inner surface 328 (see e.g. FIG. 3G) and an outer surface 332. Inner surface 328 of sidewall 322 may include threads 330 (see e.g FIG. 6A) for removably securing inner cover 300 to neck 240 of container 200 in, for example, a removable manner described in more detail below. As illustrated in FIG. 3D, outer surface 332 may include, for example, a plurality of vertical ribs 334 spaced circumferentially and equidistant from each other around at least a portion of outer surface 332 on opposing side portions 308. Gaps or spaces 336 are formed in between adjacent vertical ribs 334. In one embodiment illustrated in FIG. 3F, a slanted surface portion 338 may be formed in outer surface 332 of sidewall 322 in front portion 304. Slanted surface portion 338 creates an open pocket 340 when aligned with front tab 430 of outer ring 400, as described below, to permit radially inward flexing of front tab 430. In an alternative embodiment, gaps or spaces 336 formed in between adjacent vertical ribs 334 may provide enough room for inward flexing of front tab 430.

(38) As shown in FIG. 3B, lid 370 may be pivotally hinged to base 320 by hinge 310 at a hinge end 372 located proximal to an outer peripheral edge of deck 342 in back portion 306 for pivotal movement between a closed position closing or blocking dispensing opening 366 (see FIG. 3A) and an open position spaced from dispensing opening 366 (see FIG. 3B). Lid 370 may include a base wall 382 lying in a plane perpendicular or transverse to longitudinal axis 302 when closed. Base wall 382 is sized to fit into deck recessed portion 346 formed in top surface 344 of deck 342 in a closed position. In one example, base wall 382 of lid 370 may engage deck recessed portion 346 by, for example, an inference fit or in any other suitable snap-fit or friction manner.

(39) Base wall 382 of lid 370 includes hinge end 372 adjacent hinge 310 and free end 374 diametrically opposed to hinge 310. Base wall 382 may also include a first portion 388 extending from hinge end 372 adjacent hinge 310, a second portion 390 extending from free end 374, and a middle portion 396 extending between first portion 388 and section portion 390. In one example, first portion 388 and section portion 390 may lie in a different plane than middle portion 396. In this example, illustrated in FIG. 3B, deck recessed portion 346 may also include additional recesses 348, 350 formed on top surface 344 for accommodating first and second portions 388, 390 of lid 370 in a closed position. First and section portions 388, 390 of lid 370 are sized to correspond, cooperate and engage corresponding first and second recesses 348, 350, respectively, formed in top surface 344 of deck 342. When in a closed position, top surfaces of first and second portions 388, 390 may lie in the same plane or are flush with curved edge portions 356.

(40) As illustrated in FIG. 3D, second portion 390 of lid 370 may also include, for example, a finger tab portion 391 to aid a user in flipping up lid 370 from a closed position. Finger tab portion 391 may include an indented undersurface 392 having a thin portion 393 surrounded by two thicker portions 394.

Teeth 448 may be spaced radially equidistant or disposed at intervals in the circumferential direction around and extend axially along bottom surface 446. Each tooth 448 includes an inclined surface 450 and a stop surface 452. In one example, inclined surfaces 450 angle axially towards bottom surface 446 in a counterclockwise direction to create a ramp. Stop surface 452 extends perpendicularly outward from bottom surface 446 and substantially transverse to longitudinal axis 402. A slot or space 454 may be formed by bottom surface 446 between a stop surface 452 of one tooth 448 and an inclined surface 450 of an adjacent tooth 448. During rotation of outer ring 400 relative to inner cover 300, ratchet teeth 448 are sized and configured to interact with depressions 358 formed in semi-circular edge surfaces 356 on top surface 344 of deck 342 of inner cover 300 in accordance with one or more aspects of the present invention, as will be explained in more detail below.

(51) The number, configuration and design of the plurality of teeth 448 and the plurality of depressions 358 may be varied to accommodate the various loads or forces that may be needed or desired therethrough during opening of dispensing cap. Further, the number of teeth and/or the height and length of inclined surface of each tooth and the number of depressions and the depth and length of inclined surface of each depression may be “tuned” or vary greatly depending on the particular load or force desired for a particular application (e.g. desired torque for teeth to overcome or pass over depressions in a particular direction).

(52) In assembling dispensing cap 100, inner cover 300 is inserted telescopically into outer ring 400. As illustrated in FIGS. 6A-6B, inner cover 300 completely passes over bead or rib 416 on inner surface 414 of base wall 410 of outer ring 400, while permitting some longitudinal (up and down) movement of inner cover 300 within outer ring 400. Once assembled, outer ring 400 is configured to rotate or spin freely around inner cover 300 when no downward pressure is applied to peripheral skirt 440 by a user. Vertical ribs 334 on outer surface 332 of base sidewall 322 of inner cover 300 separate outer surface 332 from directly contacting inner surface 414 of base wall 410 of outer ring 400. After assembly, inner cover 300 is also configured to move longitudinal (e.g. up and down) relative to longitudinal axis 402 relative to outer ring 400 between bead 416 on inner surface 414 of base wall 410 and engagement with ratchet teeth 448 formed on bottom surface 446 of peripheral skirt 440.

(53) In one example, to secure inner cover 300 to container 200, threads 330 on sidewall 322 of inner cover 300 are received and engage threads 244 formed on outer surface 242 of neck 240 of container 200, as illustrated, for example, in FIGS. 6A and 6B. Once secured to container 200, dispensing cap 100 is effectively non-removable unless certain steps are taken by a user. In other words, dispensing cap 100 is not intended to be removed or opened by a user under normal operation of simple rotation of dispensing cap 100 in a counterclockwise direction.

(54) In operation, dispensing cap 100 may be used as a child resistant dispensing cap to, for example, deter or prevent young children from accessing the contents of the container to which dispensing cap 100 is attached. Inner cover 300 and outer ring 400 of dispensing cap 100 may be manipulated relative to each in several different configurations, including a locked position (see FIG. 1A), an unlocked position (see FIG. 1B) and an open position (see FIG. 1C).

(55) In a locked position, illustrated in FIGS. 1A, and 5A, front portion 404 of outer ring 400 is not aligned with front portion 304 of inner cover 300. In other words, second portion 390, including finger tab portion 391, of lid 370 is not aligned within first opening 422 to permit lid 370 to flip up. In a locked position, outer ring 400 is rotated so that at least part of first and second portions 388, 390 of lid 370 of inner cover 300 are covered by at least a part of peripheral skirt 440 of outer ring 400. In this configuration, finger tab portion 391 of second portion 390 of lid 370 passes below bottom surface 446 of peripheral skirt 440 and is inaccessible by a user.

(56) In an unlocked position, illustrated in FIGS. 1B and 5B, front portion 404 of outer ring 400 aligns with front portion 304 of inner cover 300. Outer ring 400 is rotated so that first and second portion 388, 390 of lid 370 of inner cover 300 are completely exposed within second and first opening 424, 422, respectively, formed in outer ring 400. In this configuration, no part of top surface 395 of second portion 390 or finger lid portion 391 of lid 370 is covered by peripheral skirt 440. In an unlocked position, front tab 430 aligns with front portion 304 or slanted surface portion 338 formed in base sidewall 322 of inner cover 300. In this configuration, tab 430 may flex radially inward towards slanted surface portion 338 and into open pocket 340.

(57) In an opened position, illustrated in FIG. 1C, lid 370 of inner cover 300 is pivoted upward to expose at least a portion of dispensing opening 366 formed in deck 342. To pivot lid 370 of inner cover 300 upward, a user presses finger depression 432 on outer surface 431 of front tab 430. When pressed by a user, front tab 430 flexes or pivots radially inward into open pocket 340 and towards slanted surface portion 338 of outer surface 332 of base sidewall 322 of inner cover 300. As front tab 430 flexes radially inward, indented underside 392 of finger tab portion 391 of second portion 390 of lid 370 is exposed and accessible by a user. When exposed, a user can apply upward pressure on indented underside 392 of finger tab portion 391 of lid 370 to break the interference fit of lid 370 within recessed portion(s) 346 (including recesses 348 and 350) in deck 342 and flip up lid 370 to an opened position, allowing access to the contents of container 200.

(58) Dispensing cap 100 constructed in accordance with one or more aspects of the present invention includes additional child resistant feature after dispensing cap 100 is secured to container 200. In this aspect, dispensing cap 100 cannot simply be removed from dispensing cap 100 by counterclockwise rotation. Simple counter-clockwise rotation of outer ring 400 will result in outer ring 400 freely rotating around inner cover 300 without turning or rotation of inner cover 300 relative to neck 240 of container 200. In order to remove dispensing cap 100 from a container 200, a user must apply downward pressure or push down on top surface 442 of peripheral skirt 440 of outer ring 400 in order to engage ratchet teeth 448 projecting from bottom surface 446 of peripheral skirt 440 of outer ring 400 with ratchet depressions 358 formed in curved edge surfaces 356 on top surface 344 of deck 342 of base 320 of inner cover 300. A counterclockwise torque applied to outer ring 400 while pushing down on peripheral skirt 440 will result in stop surfaces 452 of ratchet teeth 448 contacting or digging into stop surfaces 362 of ratchet depressions 358.

(59) In contrast, clockwise torque to outer ring 400 allows ratchet teeth 448 to easily push past or over ratchet depressions 358, resulting in free rotation. In one example, a “clicking” sound may be heard each time ratchet teeth 448 passes over ratchet depressions 358. Alternative child resistant structures and configurations known in the art may be used in place of the ratchet teeth 448 and ratchet depressions 358 discussed above to removably secure a cap to a container.

(60) Other attempts at manufacturing dispensing caps claiming to be child resistant and dispensing require very complex and expensive molds to produce. In contrast, a dispensing cap constructed in accordance with one or more aspects of the present invention was designed to be molded using basic molds that does not require the use of any cam action, multipiece cavities or cores, or collapsible cores required during the molding process. As a result, the investment cost for molds to produce a dispensing cap constructed in accordance with one or more aspect of the present invention is reduced, while maintaining a lower production cost.

(61) While the invention has been described in detail in connection with only a limited number of embodiments, it should be readily understood that the invention is not limited to such disclosed embodiments. Rather, the invention can be modified to incorporate any number of variations, alterations, substitutions or equivalent arrangements no heretofore described, but which are commensurate with the spirt and scope of the invention. For example, vertical spaced ribs could project from inner surface of base wall of outer ring 400 instead. Or, first end of lid may hinge at a location closer to dispensing opening rather than at a peripheral edge of deck. Or, lid may pivot open by using a flexible strap affixed to deck instead of a hinge. Additional, while various embodiments of the invention have been described, it is to be understood that aspects of the disclosure may include only some of the described embodiments. Accordingly, the invention is not to be seen as limited by the foregoing descriptions, but is only limited by the scope of the appended claims.

(62) This written description uses examples to disclose certain aspects of the invention, including the best mode, and also to enable any person skilled in the art to practice the invention, including making and using any devices or systems and performing any incorporated methods. The patentable scope of the invention is defined by the claims, and may include other examples that occur to those skilled in the art. Such other examples are intended to be within the scope of the claims if they have structural elements that do not differ from the literal language of the claims, or if they include equivalent structural elements with insubstantial differences from the literal language of the claims.
