Child resistant cap with safety collar and enhancement

Abstract

A child resistant cap includes: (a) a main closure base; (b) an outer ring that functions as a safety collar; (c) a dispensing mechanism on the base; (d) an overcap. The base attaches to a top dispensing container and the horizontally rotatable ring is attached to the base. The overcap has protrusions and the ring has corresponding cut outs. Because the overcap and ring are frictionally engaged, when one rotates, the other rotates with it. They must be held separately and rotated relative to one another to effect proper alignment for overcap remove and container dispensing. In some embodiments, the base is eliminated and the ring is attached directly to a container rim.

DETAILED DESCRIPTION OF THE EMBODIMENTS

Referring now in detail to the drawings wherein like reference numerals designate corresponding parts throughout the several views, various embodiments of the present invention are shown.

FIG. 1 shows a front partially cut, partial view of a present invention dispenser device closure. Here, main closure base 1 is shown attached to container 51.

As in any present invention embodiment, the container may have any dispensable flowable material such as liquid, sprayable liquid, gel, foam or the like. The dispensing component of the container may generally be referred to as a nozzle and could be a spray nozzle that is push activated or otherwise activated, a push-pull dispenser, a screw cap or a tilt dispenser. The main container base may simply have an opening for the nozzle or include functional parts that may connect to or otherwise come and contact with a nozzle or nozzle activator.

Main closure base 1 is attached by known conventional means and may include crimping, heat sealing, force fitting, irreversible threading or any other known attachment means. Overcap 3 is shown in its cut view along with outer ring 5. Main closure base 1 includes base track 7. In this case, it is a horizontal, circular indentation, as shown. Alternatively, it could be an annular protrusion or bead. Outer ring 5 has a track catch 9 which, in this case, is a protrusion which fits into base track 7 and allows outer ring 5 to be freely horizontally rotated about main closure base 1. As an alternative, if base track 7 were a bead protrusion, then outer ring track catch 9 would be an indentation instead of a protrusion. In other words, it is not critical as to whether the base or the outer ring has the male or female portion of the track. In any event, by “track” is meant either an indentation or a protrusion so that a complementary component rides the track. This is similar to tracks for a subway which may be protruding from the ground such as in the underground section or indented into the roadway such as above ground tracking.

Also shown in FIG. 1 are opposing griping pads 51 and 53 for a user to grip overcap 3 for aligning the makes arrow on the outer ring 5 (not shown here) with arrow 33 show on the front of main closure base 1. This embodiment also has two speed bumps not shown in this cut FIG. 1, but illustrated in FIG. 5 below and in other embodiments discussed further below.

FIG. 2 shows a top view of outer ring 5. Referring both to FIGS. 1 and 2, outer ring 5 has a ledge 21 with cut outs 11 and 19. Extending downwardly from ledge 21 and elaborated more with respect to FIG. 4 below, are elevational sections that maintain some friction between overcap 3 and outer ring 5. Thus, when a user rotates outer ring 5 without touching overcap 3, overcap 3 will travel with outer ring 5, so as to maintain non-alignment and eliminate chance of alignment for removal of overcap 3 from outer ring 5.

FIG. 3 shows a bottom view of overcap 3. Referring now to FIGS. 1 and 3, overcap 3 has a top 17 and a side wall 15 which includes inwardly extending protrusions 13 and 25 at its bottom 16. These are of adequate geometry so as to be able to fit into and slide out of cutouts 11 and 19 of ledge 21 of outer ring 5. These protrusions 13 and 25 are opposite one another and of the same geometry but could be different in geometry or not directly opposite one another as discussed with respect to FIG. 5, below. This FIG. 3 embodiment also includes speed bumps (not shown) such as are shown and described in conjunction with FIG. 5.

Also shown in FIG. 1 is a front view of spray mechanism 23 that includes spray nozzle tip 27 and a spray depressor 29. This is connected to main closure base 1 and extends downwardly therethrough so as to extend into container 51 (not shown). While spray mechanism 23 is shown to be a spray nozzle which may rely upon pressurized contents and depression for release thereof, it could very well be a pump, or other known spray mechanisms such as an atomizer.

When overcap 3 is not atop the closure shown but is separate therefrom, in one embodiment, the protrusions 13 and 25 must be aligned with cut outs 11 and 19, inserted therein and then rotated to secure the overcap and render it child resistant. However, in an alternative and more preferred embodiment, ledge 21 and/or protrusions 13 and 25 have adequate flexibility so that overcap 3 may be pressed downwardly and, with the flexion of either the protrusion or the ledge 21, or both, overcap 3 will snap into place so that the protrusions 13 and 25 end up under ledge 21 in a secure, child resistant fashion. The flexibility will be minimal such that overcap 3 cannot then be removed, except by alignment of protrusions 13 and 25 with the cut outs 11 and 19.

FIG. 4 shows a front cut, partial view of overcap 3 and outer ring 5 from FIG. 1. Identical parts are identically numbered. Protrusions 43, e.g., downwardly extending bumps or triangular cross-sectioned extensions are located on the underside of ledge 21 and similar protrusions 41 are located on the topside of protrusion 13. These nest when overcap 3 is snapped onto outer ring 5 and enhance the friction between the overcap 3 and the outer ring 5. In fact, due to the friction between the overcap 3 and the outer ring 5, mentioned above, if either only the overcap 3 or only the outer ring 5 is rotated, the other will rotate with it and the non-alignment feature will be maintained. Thus, in preferred embodiments, a user can only remove overcap 3 by holding outer ring 5 with one hand and rotating overcap 3 with the other hand or vise versa so as to overcome the friction between the two and align the protrusions 13 and 25 with cut outs 11 and 19 for subsequent removal of the overcap 3 from the outer ring 5 to provide access to the spray mechanism 23.

FIG. 5 shows a top view of an outer ring 71 that may be used in an alternative embodiment closure of the present invention. Here, ledge 73 has cut outs 75 and 77 that are not directly opposite one another and are of different sizes. This further restricts the removal of an overcap therefrom because, when two cut outs are opposite one another, there would be two opportunities or positions upon a 360 degree rotation for removal of an overcap. However, with the arrangement shown in FIG. 5, only one unique position will allow for proper alignment and removal of an overcap. In addition to the foregoing, hidden track 81 has two vertical speed bumps 83 and 85. These are located on opposing sides of cut out 77, so as to inhibit accidental movement between the ring and the overcap to decrease accidental proper alignment and undesired opening of the overcap. A user must overcome the friction between the protrusions and the speed bumps to achieve proper alignment for overcap removal and subsequent container dispensing.

FIG. 6 shows a front, uncut view of the present invention overcap 3 shown in FIG. 1, including an alignment arrow 65. A user will hold the outer ring 5 in one hand, the overcap 3 in the other hand, rotate one relative to the other to overcome the friction between the ledge and the protrusions and when arriving at the speed bumps, overcome that frictional resistance, align the alignment arrow 65 with arrow 33 (FIG. 1), lift the overcap 3 off the ring 5 and activate spray depressor 29 as desired.

FIG. 7 shows front, partially cut view of an alternative embodiment present invention overcap 101 with sidewall 103, open bottom 105, with a measuring cup 111 with predetermined volume 115, with graduated dosage markers, such as marker 117 and with flat (e.g., printed), rather than indented, griping pads 107 and 109. Alignment arrow 119 is shown in front with the griping pads 107 and 109 on the sides. Alternatively, these griping pads 107 and 109 could be front and back positioned.

FIG. 8 shows a front, partially cut view of another embodiment of a present invention child resistant cap with an outer ring 201 that includes a built-in gel or foam activator 213 and and foam or gel dispensing nozzle 211, and an overcap 203 which includes a measuring cup 231. Outer ring 201 is directly attached to the rim of container 251 so that it is horizontally rotatable thereabout. Ring 201 includes an inside recess for attachment to the container rim, and an alignment arrow 205, as well as a track 207 with speed bumps 215 and 217. It has a ledge 209 with a plurality of cutouts, such as cut out 219. Ring 201 has overcap 203 attached to it and this overcap 203 has an open top 229 and sidewall 225, and includes protrusions, such as protrusion 227 frictionally engaged with and under ledge 209. In this embodiment, measuring cup 231 had a formed center 233 to fit above nozzle 211, as shown. The invention here functions in identical fashion as the embodiments described in the preceding Figures. However, because the ring 201 is directly attached to the container rim, a base piece has been eliminated. Further, nozzle 211 and nozzle activator 213 are integrally formed into the ring 201, eliminating another separate production piece. This is clear from its top view. FIG. 9 illustrates a top view of outer ring 201 shown in FIG. 8, showing both cut outs 219 and 249, and illustrating the position and tilt capability of the activator 213 (due to the cut portions in the top of ring plate 245).

FIG. 10 shows front, cut view of an alternative embodiment present invention overcap 301 with sidewall 307 and top 303. On the inside of sidewall 307 is one of a plurality of protrusions, protrusion 309. Also included is a vertical friction pad 311. There may be a plurality of such friction pads and these further reduce accidental slippage and alignment between the overcap and the ring (not shown) as the friction pad presses against the horizontal outside of the ring ledge or other external surface.

Although particular embodiments of the invention have been described in detail herein with reference to the accompanying drawings, it is to be understood that the invention is not limited to those particular embodiments, and that various changes and modifications may be effected therein by one skilled in the art without departing from the scope or spirit of the invention as defined in the appended claims. For example, components may reverse the male and female aspects without exceeding the scope of the invention. The overcap may snap into the inside of a ring instead of on its outside with the track of the ring being on an inside surface instead of an outside surface. Also, for example, the protrusions and cut outs could be reversed and located on the ring and overcap, respectively.

The child resistant cap with safety collar and enhancement of claim 1 wherein at least one of said ledge and said at least two protrusions two are flexible so as to permit insertion of said overcap onto said outer ring without alignment of said at least two protrusions and said at last two cut outs, and are upwardly inflexible so as to prevent removal of said overcap from said outer ring, except when said at least two protrusions and said at least two cut outs are in proper alignment.

10. The child resistant cap with safety collar and enhancement of claim 1 wherein said overcap further includes a plurality of vertical friction pads located on its inside and positioned to be adjacent the outside of said ledge when on said outer ring.

11. A child resistant cap with safety collar and enhancement for direct attachment to a container having a rim of greater diameter than its neck, which comprises:

a) an outer ring having a circular inside wall with a horizontal track thereon for attachment to the rim of a container having a rim of greater diameter than its adjacent neck, said container having a top dispenser, so as to connect said outer ring to said rim so as to be horizontally and freely rotatable thereabout, said outer ring also having a top with an outwardly biased ledge for retaining an overcap, and having at least two cut outs on said ledge to permit an overcap to be inserted onto and removed from said outer ring, and having at least two speed bumps located below said outwardly biased ledge adapted to reduce for horizontal movement of an overcap until minor frictional engagement is surpassed by minimal force;

b) an overcap having a circular bottom adapted to be inserted into said outer ring and over said container, said bottom having at least two protrusions thereon which have geometries of adequate size to freely move through said at least one of said at least two cut outs of said ledge of said outer ring and when said overcap is so inserted and rotated, of adequate size and geometry to prevent removal of said overcap from said outer ring, except when said at least two protrusions and said at least two cut outs are in proper alignment, said overcap having at least two opposing griping pads located on its exterior; and,

 further wherein said outer ring ledge has an underside and said at least two protrusions of said overcap have tops wherein the underside of said ledge and the top side of said at least two protrusions are in frictional contact with one another when said overcap is inserted into said outer ring such that when one of said outer ring and said overcap are rotated, the other of said outer ring and said overcap rotates therewith, and wherein said frictional contact may be overcome manually by holding one of said outer ring and said overcap and rotating the other of said outer ring and said overcap.

12. The child resistant cap with safety collar and enhancement of claim 11 wherein said main closure base has means for attachment to a container.

13. The child resistant cap with safety collar and enhancement of claim 12 wherein said means for attachment is threading.

14. The child resistant cap with safety collar and enhancement of claim 11 wherein said at least two speed bumps are two speed bumps, having each speed bump on opposing sides of one of said at least two cut outs.

15. The child resistant cap with safety collar and enhancement of claim 11 wherein said cut outs are directly opposite one another.

16. The child resistant cap with safety collar and enhancement of claim 11 wherein said overcap includes a measuring cup at its top.

17. The child resistant cap with safety collar and enhancement of claim 11 wherein said there are at least three cut outs and a corresponding number of protrusions, said cut outs and protrusions being evenly spaced from one another.

18. The child resistant cap with safety collar and enhancement of claim 11 wherein said underside of said ledge and said top of said at least one protrusions have non-smooth topographies to enhance said frictional contact.

19. The child resistant cap with safety collar and enhancement of claim 11 wherein at least one of said ledge and said at least two protrusions two are flexible so as to permit insertion of said overcap onto said outer ring without alignment of said at least two protrusions and said at last two cut outs, and are upwardly inflexible so as to prevent removal of said overcap from said outer ring, except when said at least two protrusions and said at least two cut outs are in proper alignment.

20. The child resistant cap with safety collar and enhancement of claim 11 wherein said overcap further includes a plurality of vertical friction pads located on its inside and positioned to be adjacent the outside of said ledge when on said outer ring.
