Definitions
- the present invention relates to closure members for containers, bottles and the like, and, more particularly, to closure members which are particularly well adapted for use on dispensing containers for medicinal agents.
- Present medical drugs have a predetermined therapeutic range in which the effects of taking the drug are beneficial. Under-utilization of a drug may endanger the user with the drug's side effects without reaching levels necessary for a therapeutic action. On the other hand, over-utilization may cause side effects or toxicity to a much greater extent than any possible benefit. Thus, it is critically important that a patient follows prescribed directions on medications; yet, frequently patients forget whether they have taken medication and either omit doses or repeat them.
- the reminder cap of the present invention affords improvements over closure members of the type known in the art.
- US-A-4011829 (which corresponds to DE-A-2543251) discloses a reminder closure member in which indicia means in the form of an indicia-bearing disc is located between inner and outer closure members to turn relative to each other at each container opening/closing operation.
- US-A-4220247 discloses five different embodiments of reminder closure member each of which has inner and outer housing portions that rotate together to unscrew the closure member from its container and which allow a degree of relative rotation between them when exceeding the fully closed position in the rescrewing of the closure member on the container.
- indicia on the inner housing and some reference means (e.g. a sight opening) in the outer housing it can be arranged that each closure member removal can be accompanied by a change in the referenced indicia mark.
- the indicia are fixedly marked on the indicia means constituted by the inner housing.
- a preferred embodiment of the present invention includes a plurality of indicia disposed upon an insertable disc removably mounted in a relatively stationary manner on the inner housing.
- indicia may be disposed upon an insertable indicia cylinder removably mounted in a relatively stationary manner to vertical cylindrical walls of an inner housing.
- the insertable indicia disc or cylinder may be held stationary by adhesive means, interlocking or keyed holes and protrusions, tongue and grooves or other similar means.
- the indicia may also be simply disposed upon paper or other thin material to be secured around or adhered to the inner housing by adhesive.
- the present invention can be readily adapted for use with dispensing containers of different sizes and shapes.
- Removable inner and outer housings and the indicia means can be modified to resemble the shape of the container opening to be sealed.
- the present invention also has application to ophthalmic drop dispensing bottles wherein the pointed projecting drop dispensing tips of the bottles make the use of closure members having substantially conical portions advantageous.
- a closure member according to the present invention can have a removable conical indicia means and an outer housing having an open top allowing the inner housing to project therethrough.
- a further embodiment of the present invention includes closure members having multiple openings disclosing different predetermined types of indicia. Each opening may represent a different dose schedule. Unwanted regimens may be covered by opaque tape. Such an embodiment permits the present invention to have a wide range of applications.
- the present invention affords a reminder cap closure member which may be latched to a container on which it is mounted to render it difficult for a young child to open while providing a closure member that can be readily opened and closed by the average adult.
- a closure member embodying the principles of the present invention is mounted on a container 12 in closing relation thereto.
- the closure member 11 is comprised of the following major elements; an outer housing 21 having an aperture 23 and abutment means 25 positioned inwardly of the inside corner thereof, an inner housing 41 having a projecting rim 44 thereon and groove means 42 therein, inner cap member 51 for securing the closure member 11 to the container 12, and removable indicia 62 adapted to be affixed in a relatively stationary manner to the inner housing 41.
- the closure member 11 may have any cross- sectional shape; however, a number of factors may influence the shape used. Closure members 11 having a cylindrical shape are well adapted for use on bottles and vials having threaded openings, as shown in Fig. 1. The cylindrical shape allows for the positioning of an aperture or apertures 23 upon the top planar surface of the outer housing 21 or about the vertical cylindrical wall, as shown in Fig. 11.
- the removable indicia member is comprised of a disc 62 secured to the inner housing 41 by suitable means, such as an adhesive.
- the disc 62 is held relatively stationary on the inner'housing 41 by a locking indentation 64 about the circumference of the disc 62, which cooperates with a protrusion 65 about the projecting rim 44 of the inner housing 41.
- Fig. 5 illustrates a disc 62 having an elongated slot 63 therein which would fit upon a complementary protrusion (not shown) on the upper surface 75 of the inner housing 41 to affix the disc 62 in a relatively stationary manner to the inner housing 41.
- FIG. 13 illustrates a disc 62 having a square-keyed opening 73 therein in its center which would fit upon a complementary protrusion (not shown) extending from the upper surface 75 of the inner housing 41 to affix the disc 62 in a relatively stationary manner to the inner housing 41, in accordance with the present invention.
- the inner housing 41 includes an upwardly projecting rim 44 which provides a circular space between the inner housing 41 and the outer housing 21 sufficient to provide space for the disc 62 to prevent the disc 62 from interfering with the relative rotation of the inner and outer housings 41 and 21, respectively, when the outer housing 21 rotates relative to the inner housing 41, 51 to reveal a new indicium in the aperture 23.
- Figure 3 shows the grooves 42 in the rim 44 as being substantially perpendicular recessed openings, these are desirably of a depressed ramp configuration (as shown in Figures 9 and 10 shortly to be discussed) or of a trapezoidal shape configuration (as shown in Figures 22 and 23 yet to be discussed).
- abutment means 25 includes at least one projection extending inwardly and downwardly from the corner of the outer housing 21 which engages in a respective one of the grooves 42 in a manner to stop rotation of the inner and outer housings relative to each other in one direction of rotation of the closure member 11 on the container 12, but yieldingly resists rotation of the inner and outer housings relative to each other in the opposite direction of rotation of the closure member on the container.
- the closure member 11 of the present invention is equipped with threads or other latching means 55 for securing to a container or bottle 12.
- the closure member 11 is mounted over an inner cap member 51 equipped with means for latching and securing to the container 12, such as threads 55.
- the inner cap member 51 is nested within the inner housing 41 of the closure member 11 and secured by a flange 45 extending around the bottom portion of the inner housing 41 and snugly fitting into an indentation 52 on the inner cap member.
- a plurality of spring fingers or elements 20 extend downwardly and rests upon the top planar surface 76 of the inner cap member 51.
- Projection means 53 extend upwardly from the top planar surface 76 of the inner cap member 51 and permit the spring fingers 20 to slideably deflect upwardly over the projection means 53 in one rotational direction, and prevent the spring fingers 20 from rotatably moving past the projection means 53 in the opposite direction when the spring fingers 20 and the projection means 53 become engaged.
- Downwardly projecting teeth 46 extend from the inner housing 41 and upwardly projecting grooves 54 extend from the inner cap member 51 in a complementary spaced manner.
- the teeth 46 and grooves 54 are prevented from meshing with each other by the upward force exerted upon the inner housing 41 by the spring fingers 20 engaging the top planar surface 76 of the inner cap member.
- Downward forces upon the outer housing 21 are transferred to the inner housing 41 by engagement of abutment means 25 with the grooves 42 in the upwardly-projecting rim 44 on the inner housing. This engagement compresses the spring fingers 20 and narrows the space between the inner cap member 51 and the inner housing 41 thereby resulting in the engagement of teeth 46 of the inner housing and grooves 54 of the inner cap member.
- the inner cap member can be rotated in unison with the inner and outer housings in the direction in which the spring fingers 20 would otherwise slideably deflect over the projection means 53.
- the spring fingers 20 again force the inner housing 41 upward, disengaging the teeth 46 from grooves 54.
- rotation of the outer housing 21 and the inner housing 41 is ineffective in rotating the inner cap member 51 in the untightening direction, unless the cap member has already been loosened because of prior engagement of the teeth 46 with the grooves 54.
- This construction is highly effective in preventing the accidental opening of a container by a young child.
- FIG. 7 Another embodiment of the present invention is illustrated in Figs. 6 and 7.
- the container 12 in Fig. 7 includes locking ribs 14 projecting outwardly about the upper/outer portions of the rim of the container 12.
- Each locking rib 14 includes a curved area 15 extending downwardly from the top of the locking rib 14 to a locking channel 18 extending upward perpendicularly to the rim of the container 12.
- the forward wall of the channel 18 affords a forward stop 16.
- the rear wall of the locking channel 18 affords a rear stop 17 projecting downwardly parallel to the forward stop 16 and below the curved area 15.
- the inner housing 41 of the closure member 11 has lugs 48 projecting inwardly around the lower rim of the inner housing 41 in a spaced manner corresponding to the spacings of the locking ribs 14 of the container 12 of Fig. 7.
- a circular resilient seal 28 has a flange 29 extending radially outward around the circumference beyond the inwardly projecting lugs 48 to retain the seal 28 within the cavity formed by the cylindrical wall 57 and horizontal wall 47 of the inner housing 41.
- a rim 30 extends downwardly from the flange 29 for nesting securely against the cylindrical inner wall of the container 12 illustrated in Fig. 7.
- the circular resilient seal 28 projects upwardly to rest against projection 20 extending downwardly from the bottom surface of the horizontal wall 47 of the inner housing 41.
- the container 12, illustrated in Fig. 7, can be forced upwardly into the cavity within the inner housing 41 such that the rim of the container 12 rests against the flange 29.
- the center area of the seal 28 forces the seal rim 30 against the inner walls of the container 12.
- the lugs slide downwardly over the curved area of the locking rib 14 and into the locking channel 18.
- the forward and rear stops 16 and 17 will prevent further movement of the lugs 48 of the inner housing 41 and will secure the closure member upon the container when the closure member 11 and the container 12 are no longer compressing.
- the lugs 48 are retained in the locking channel 18 by the upward force exerted on the inner housing 41 by the compressed seal 28 engaging projection 20.
- a removable indicia member in the form of a disc 62 is disposed upon the upper planar surface of the inner housing 41.
- a circular space is provided between the outer housing 21 and the inner housing 41 by a vertically projecting portion 44 which prevents the binding of the indicia member 62 when a downward force is exerted upon the outer housing 21 during an opening or closing operation.

Abstract
Description
- The present invention relates to closure members for containers, bottles and the like, and, more particularly, to closure members which are particularly well adapted for use on dispensing containers for medicinal agents.
- Present medical drugs have a predetermined therapeutic range in which the effects of taking the drug are beneficial. Under-utilization of a drug may endanger the user with the drug's side effects without reaching levels necessary for a therapeutic action. On the other hand, over-utilization may cause side effects or toxicity to a much greater extent than any possible benefit. Thus, it is critically important that a patient follows prescribed directions on medications; yet, frequently patients forget whether they have taken medication and either omit doses or repeat them.
- This problem is particularly severe for elderly patients who are generally beset with multiple ailments requiring numerous drugs and directions. The fading memory and confusion that come with age further compound the problem. Oftentimes, elderly patients could well lead independent self-sufficient lives but for their inability to follow a therapeutic regimen necessary to their health and well-being. Caps of the "reminder" type will be an important adjunct in drug therapy as the number of elderly people increases and new potent drugs are utilized.
- The reminder cap of the present invention affords improvements over closure members of the type known in the art.
- US-A-4011829 (which corresponds to DE-A-2543251) discloses a reminder closure member in which indicia means in the form of an indicia-bearing disc is located between inner and outer closure members to turn relative to each other at each container opening/closing operation.
- My earlier US-A-4220247 discloses five different embodiments of reminder closure member each of which has inner and outer housing portions that rotate together to unscrew the closure member from its container and which allow a degree of relative rotation between them when exceeding the fully closed position in the rescrewing of the closure member on the container. By locating indicia on the inner housing and some reference means (e.g. a sight opening) in the outer housing it can be arranged that each closure member removal can be accompanied by a change in the referenced indicia mark. In all the embodiments disclosed in US-A-4220247 the indicia are fixedly marked on the indicia means constituted by the inner housing.
- What constitutes the present invention is disclosed in the following claim 1 and is distinguished from the prior art (disclosed in US-A-4220247) by having the indicia means removably mounted on the inner housing in a relatively stationary manner.
- A preferred embodiment of the present invention includes a plurality of indicia disposed upon an insertable disc removably mounted in a relatively stationary manner on the inner housing.
- Alternatively, indicia may be disposed upon an insertable indicia cylinder removably mounted in a relatively stationary manner to vertical cylindrical walls of an inner housing. The insertable indicia disc or cylinder may be held stationary by adhesive means, interlocking or keyed holes and protrusions, tongue and grooves or other similar means. The indicia may also be simply disposed upon paper or other thin material to be secured around or adhered to the inner housing by adhesive.
- The present invention can be readily adapted for use with dispensing containers of different sizes and shapes. Removable inner and outer housings and the indicia means can be modified to resemble the shape of the container opening to be sealed. The present invention also has application to ophthalmic drop dispensing bottles wherein the pointed projecting drop dispensing tips of the bottles make the use of closure members having substantially conical portions advantageous. For these applications, a closure member according to the present invention can have a removable conical indicia means and an outer housing having an open top allowing the inner housing to project therethrough.
- A further embodiment of the present invention includes closure members having multiple openings disclosing different predetermined types of indicia. Each opening may represent a different dose schedule. Unwanted regimens may be covered by opaque tape. Such an embodiment permits the present invention to have a wide range of applications.
- The present invention affords a reminder cap closure member which may be latched to a container on which it is mounted to render it difficult for a young child to open while providing a closure member that can be readily opened and closed by the average adult.

- A closure member embodying the principles of the present invention, generally designated by numeral 11, as best seen in Fig. 1, is mounted on a
container 12 in closing relation thereto. As shown in Figs. 2-4, the closure member 11 is comprised of the following major elements; anouter housing 21 having anaperture 23 and abutment means 25 positioned inwardly of the inside corner thereof, aninner housing 41 having a projectingrim 44 thereon and groove means 42 therein,inner cap member 51 for securing the closure member 11 to thecontainer 12, andremovable indicia 62 adapted to be affixed in a relatively stationary manner to theinner housing 41. - The closure member 11 may have any cross- sectional shape; however, a number of factors may influence the shape used. Closure members 11 having a cylindrical shape are well adapted for use on bottles and vials having threaded openings, as shown in Fig. 1. The cylindrical shape allows for the positioning of an aperture or
apertures 23 upon the top planar surface of theouter housing 21 or about the vertical cylindrical wall, as shown in Fig. 11. - In the closure member 11, as depicted in Figs. 1-4 the removable indicia member is comprised of a
disc 62 secured to theinner housing 41 by suitable means, such as an adhesive. As illustrated in Figs. 3 and 4, thedisc 62 is held relatively stationary on the inner'housing 41 by alocking indentation 64 about the circumference of thedisc 62, which cooperates with aprotrusion 65 about the projectingrim 44 of theinner housing 41. Additionally, Fig. 5 illustrates adisc 62 having anelongated slot 63 therein which would fit upon a complementary protrusion (not shown) on theupper surface 75 of theinner housing 41 to affix thedisc 62 in a relatively stationary manner to theinner housing 41. Fig. 13 illustrates adisc 62 having a square-keyed opening 73 therein in its center which would fit upon a complementary protrusion (not shown) extending from theupper surface 75 of theinner housing 41 to affix thedisc 62 in a relatively stationary manner to theinner housing 41, in accordance with the present invention. - In Figs. 2 and 3, the
inner housing 41 includes an upwardly projectingrim 44 which provides a circular space between theinner housing 41 and theouter housing 21 sufficient to provide space for thedisc 62 to prevent thedisc 62 from interfering with the relative rotation of the inner andouter housings outer housing 21 rotates relative to theinner housing aperture 23. Although Figure 3 shows thegrooves 42 in therim 44 as being substantially perpendicular recessed openings, these are desirably of a depressed ramp configuration (as shown in Figures 9 and 10 shortly to be discussed) or of a trapezoidal shape configuration (as shown in Figures 22 and 23 yet to be discussed). Additionally the abutment means 25 includes at least one projection extending inwardly and downwardly from the corner of theouter housing 21 which engages in a respective one of thegrooves 42 in a manner to stop rotation of the inner and outer housings relative to each other in one direction of rotation of the closure member 11 on thecontainer 12, but yieldingly resists rotation of the inner and outer housings relative to each other in the opposite direction of rotation of the closure member on the container. - The closure member 11 of the present invention is equipped with threads or other latching means 55 for securing to a container or
bottle 12. Referring to Fig. 2, the closure member 11 is mounted over aninner cap member 51 equipped with means for latching and securing to thecontainer 12, such asthreads 55. Theinner cap member 51 is nested within theinner housing 41 of the closure member 11 and secured by a flange 45 extending around the bottom portion of theinner housing 41 and snugly fitting into anindentation 52 on the inner cap member. - A plurality of spring fingers or
elements 20 extend downwardly and rests upon the topplanar surface 76 of theinner cap member 51. Projection means 53 extend upwardly from the topplanar surface 76 of theinner cap member 51 and permit thespring fingers 20 to slideably deflect upwardly over the projection means 53 in one rotational direction, and prevent thespring fingers 20 from rotatably moving past the projection means 53 in the opposite direction when thespring fingers 20 and the projection means 53 become engaged. - Downwardly projecting
teeth 46 extend from theinner housing 41 and upwardly projectinggrooves 54 extend from theinner cap member 51 in a complementary spaced manner. Theteeth 46 andgrooves 54 are prevented from meshing with each other by the upward force exerted upon theinner housing 41 by thespring fingers 20 engaging the topplanar surface 76 of the inner cap member. Downward forces upon theouter housing 21 are transferred to theinner housing 41 by engagement of abutment means 25 with thegrooves 42 in the upwardly-projectingrim 44 on the inner housing. This engagement compresses thespring fingers 20 and narrows the space between theinner cap member 51 and theinner housing 41 thereby resulting in the engagement ofteeth 46 of the inner housing andgrooves 54 of the inner cap member. When theteeth 46 andgrooves 54 are so engaged, and the abutment means 25 andgrooves 42 of the inner andouter housings spring fingers 20 would otherwise slideably deflect over the projection means 53. When the force upon theouter housing 21 is released, thespring fingers 20 again force theinner housing 41 upward, disengaging theteeth 46 fromgrooves 54. In this position, rotation of theouter housing 21 and theinner housing 41 is ineffective in rotating theinner cap member 51 in the untightening direction, unless the cap member has already been loosened because of prior engagement of theteeth 46 with thegrooves 54. This construction is highly effective in preventing the accidental opening of a container by a young child. - Another embodiment of the present invention is illustrated in Figs. 6 and 7. The
container 12 in Fig. 7 includes lockingribs 14 projecting outwardly about the upper/outer portions of the rim of thecontainer 12. Each lockingrib 14 includes a curved area 15 extending downwardly from the top of the lockingrib 14 to a locking channel 18 extending upward perpendicularly to the rim of thecontainer 12. The forward wall of the channel 18 affords a forward stop 16. The rear wall of the locking channel 18 affords a rear stop 17 projecting downwardly parallel to the forward stop 16 and below the curved area 15. - Referring now to Fig. 6, the
inner housing 41 of the closure member 11 haslugs 48 projecting inwardly around the lower rim of theinner housing 41 in a spaced manner corresponding to the spacings of the lockingribs 14 of thecontainer 12 of Fig. 7. A circular resilient seal 28 has a flange 29 extending radially outward around the circumference beyond the inwardly projectinglugs 48 to retain the seal 28 within the cavity formed by the cylindrical wall 57 and horizontal wall 47 of theinner housing 41. A rim 30 extends downwardly from the flange 29 for nesting securely against the cylindrical inner wall of thecontainer 12 illustrated in Fig. 7. The circular resilient seal 28 projects upwardly to rest againstprojection 20 extending downwardly from the bottom surface of the horizontal wall 47 of theinner housing 41. Thecontainer 12, illustrated in Fig. 7, can be forced upwardly into the cavity within theinner housing 41 such that the rim of thecontainer 12 rests against the flange 29. As the flange 29 is forced upward by thecontainer 12, the center area of the seal 28 forces the seal rim 30 against the inner walls of thecontainer 12. As the inner housing is rotated in a clockwise direction, the lugs slide downwardly over the curved area of the lockingrib 14 and into the locking channel 18. The forward and rear stops 16 and 17 will prevent further movement of thelugs 48 of theinner housing 41 and will secure the closure member upon the container when the closure member 11 and thecontainer 12 are no longer compressing. Thelugs 48 are retained in the locking channel 18 by the upward force exerted on theinner housing 41 by the compressed seal 28 engagingprojection 20. - A removable indicia member in the form of a
disc 62 is disposed upon the upper planar surface of theinner housing 41. A circular space is provided between theouter housing 21 and theinner housing 41 by a vertically projectingportion 44 which prevents the binding of theindicia member 62 when a downward force is exerted upon theouter housing 21 during an opening or closing operation. Anabutment rib 25 extends inwardly from the inner cylindrical wall of theouter housing 21 to engage with abutmemt grooves (not shown) disposed upon the outercylindrical wall 40 of theinner housing 41, as illustrated by theabutment grooves 42 in Fig. 12. However, it should be noted that it is within the scope of the present invention that theinner housing 41 may include aprojection portion 44 withgrooves 42 therein (as shown in Fig. 3), which cooperate with abutment means 25 extending inwardly and downwardly from the inside of the outer housing 21 (as shown in Fig. 2). Anaperture 23 is provided in the top surface of theouter housing 21 for viewing the indicia disposed upon thedisc 62. As the closure member 11 is pushed down and turned counter-clockwise to open, the abutment means of the inner andouter housings housings lugs 48 reach rear stop 17. Further rotation of theouter housing 21 causes the abutment means 25 thereon to yield permitting theouter housing 21 to rotate relative to theinner housing 21 and to reveal a new indicia in theaperture 23. It will be seen that this construction of the present invention is also highly effective in preventing a young child from accidentally opening the closure while still providing a novel closure member having reminder features therein. - As shown in Figs. 8-10, another embodiment of the present invention has particular application to ophthalmic drop dispensing bottles wherein the pointed projecting tip portion of the bottles make the use of closure members having conical proportions advantageous. Referring now to the exploded side view of the closure member 11 as shown in Fig. 9, the closure member 11 includes an
outer housing 21 and aninner housing 41 having an open bottom equipped with threads (not shown) for sealably mounting the closure member ontothreads 13 conveniently positioned near the top of thecontainer 12, as is known in the art. An indicia disc or means 62, conforming to the dimensions of theinner housing 41, is removably mounted thereto and secured by either adhesive means (not shown) or by aligning thedisc 62, having a cut-out recess 64 therein, with aprojection 65 extending upwardly from theinner housing 41. Such alignment secures the indicia disc to theinner housing 41. However, it is within the scope of the embodiments described in this specification, that a plurality ofindicia 68 best shown in Fig. 12, may be disposed upon the upper surfaces of theinner housing 41 in a spaced manner. As shown in Fig. 9, an outwardly projectingridge 43 extends around the lower base of theinner housing 41. Theouter housing 21 is rotatably mounted to theinner housing 41 and is secured in place by a retaininggroove 39 extending around the base of the inner wall of theouter housing 21 for receiving the outwardly projectingridge 43 of theinner housing 41. - Abutment means 25 are disposed upon the vertical cylindrical wall of the
outer housing 21. Referring now to Fig. 10, the abutment means of theinner housing 41 includestriangular grooves 42 having one wall 42a which is substantially perpendicular to the circumference of the housing and a secondinclined wall 42b. Abutment means are also disposed on the vertical cylindrical wall of theouter housing 21. The abutment means includes a wedge-shapedrib 25 pojecting inwardly from the inner cylindrical wall of theouter housing 21. As can best be seen in Fig. 10, the wedge-shapedrib 25 has oneface 25a substantially perpendicular to the circumference of the housing and an inclined face 25b extending from the housing which complements the shape of the abutment means disposed on theinner housing 41. The abutment means on the inner and outer housings, 21 and 41, are positioned to mutually engage during the relative rotation of the inner and outer housings, in a manner effective to stop the relative rotation of the inner and outer housings in one direction and yieldingly resist the relative rotation of the inner and outer housing in the opposite direction. - An
aperture 23 extends through the conical portion 24 of theouter housing 21.Indicia 68 are disposed on the indicia disc or means 62 in a spaced manner corresponding to the spacings of the abutment members such that at least one of the indicia is visible through the aperture when the abutment members are engaged. When the closure member 11 is rotatably mounted to thecontainer 12, the wedge-shapedrib 25 on theouter housing 21 engages a predeterminedtriangular groove 42 in theinner housing 41 to indicate the desired indicia and that the closure member 11 is secured to thecontainer 12. - A further embodiment of the present invention is illustrated in Figs. 11-13. The closure member 11 illustrated in Fig. 11 has a similar construction to that already described previously but for the plurality of
apertures 23a, 23b disposed upon the top of the outer housing and apertures 23c and 23d disposed along the cylindrical wall of theouter housing 21.Explanatory indicia 31 are disposed upon the surface of theouter housing 21 about the apertures 23a through 23d. The different indicia disposed upon the outer housing and their respective apertures represent different regimens or schedules. At the time of dispensing, unwanted schedules or regimens may be blocked out by masking theindicia 31 andapertures 23 with opaque tape or the like. - Referring now to Fig. 12, the
inner housing 41 of the closure member 11 is shown having a removable indicia member in the form of adisc 62 disposed upon the upper surface of theinner housing 41. An upwardly projectingrim 44 prevents the rotation of the inner andouter housings disc 62. Abutment means in the form ofdepressed grooves 42 are disposed in a spaced vertical manner along the cylindrical wall of theinner housing 41 for engaging abutment means or a wedge-shaped rib, shown as 25 in Fig. 13, on the inner surfaces of the cylindrical wall of theouter housing 21. A plurality ofindicia members 68 are disposed upon the surfaces of thecylindrical wall 40 of theinner housing 41. An outwardly projectingridge 43 extends around the bottom of the cylindrical wall of theinner housing 41 to engage thebottom portion 22 of theouter housing 21 to rotatably secure theinner housing 41 within theouter housing 21 and to permit the indexing of the indicia past the apertures 23a and 23d, as desired, when the member 11 has been threaded onto a closure (not shown) bythreads 55. Again, it should be pointed out that it is within the scope of the present embodiment that theinner housing 41 and the projectingrim 44 may include grooves on the top thereof which cooperate with abutment means 25 extending inwardly and downwardly from the outer housing, as shown in Figs. 2 and 3. - A further embodiment of the present invention is illustrated in Figs. 14-17 wherein the closure member 11 is comprised of an
outer housing 21, aninner housing 41 and aninner cap member 51. Theinner housing 41 is shown having a removable indicia member in the form of adisc 62 disposed upon the upper surface of theinner housing 41. An upwardly projectingrim 44 prevents the rotation of the inner andouter housings disc 62. Although not shown, thedisc 62 includes anopening 64 therein which cooperates with aprojection 65 to prevent movement of the disc with respect to theinner housing 41. Although not shown in the drawings, abutment means in the form ofdepressed grooves 42 are disposed and spaced in a vertical manner along the cylindrical wall of theinner housing 41 for engaging a wedge-shaped abutment means, similar toelement 25 in Fig. 10, on the inner surfaces of the cylindrical wall of theouter housing 21. Additionally, theouter housing 21 includes anopening 23 therein which cooperates with theindicia disc 62 to reveal indicia thereon. When theinner housing 41 is nested within theouter housing 21, an outwardly projectingridge 43 extends around the bottom of the cylindrical wall of theinner housing 41 to engage thebottom portion 22 of theouter housing 21 to rotatably secure the inner housing within the outer housing and to facilitate indexing of the indicia past theaperture 23 when the closure member 11 is threaded onto a closure (not shown) bythreads 55. - A plurality of
spring fingers 20 extend downwardly from the inside of theinner housing 41 and rest upon the topplanar surface 76 of theinner cap member 51. Abutment means 46. (Fig. 16) extend downwardly from the inside corner of the inner housing and are engageable with complementary grooves 54 (Fig. 23) located in therim 56 of theinner cap member 51. Preferably, the abutment means 46 andgrooves 54 are of a trapezoidal shaped configuration, as shown in Figs. 22 and 23. - The abutment means 46 and
grooves 54 are only partially meshed with each other when theouter housing 21 is in the outward "at rest" position because of the outward force exerted upon theouter housing 21 by thespring fingers 20 engaging the topplanar surface 76 of thecap member 51. Importantly, the abutment means 46 andgrooves 54 of the inner housing and inner cap member, respectively, are normally only partially engaged and the inner cap can be rotated in unison with the outer housing in the direction in which the inner cap is tightened upon the container. A downward force upon theouter housing 21 is transferred to theinner cap member 51 by compressing thespring fingers 20 and narrowing the space between theinner cap member 51 andouter housing 21 thereby fully engaging the abutment means 46 of the housing andgrooves 54 of the inner cap member, a position as shown in Fig. 23. When the force upon theouter housing 21 is released, thespring fingers 20 again force theouter housing 21 upward, partially disengaging the abutment means 46 fromgrooves 54, the position as shown in Fig. 22. In this relaxed position, rotation of theouter housing 21 with respect to theinner housing 41 is effective in tightening theinner cap member 51 onto the closure. - This results because the projection end 46d is engaged with groove side 54b, as shown in Fig. 22. However, if it is desired to unscrew the closure member 11 from the container, when the cap member is in a fully tight condition, the rotation of the
outer housing 21 in the untightening direction results in the abutment means 46 deflecting past thegroove 54 such that such rotation of the outer housing is ineffective in removing theinner cap member 51 from the closure. - Thus, the closure member Will close to a fully tight condition about the closure but will not open from its fully tight condition unless the outer housing is downwardly forced against the inner cap member to fully engage the abutment means 46 with the
grooves 54, a position as shown in Fig. 23. When the inner cap member has been released from its fully tight condition even the partial engagement of the abutment means 46 with thegrooves 54 which arises when the outer housing is in the relaxed position, is sufficient to rotate the inner cap member and remove the same from the closure. This results because the corner 54a of the groove 54 (Fig. 23) is rounded to permit partial engagement with the end surface 46a of the abutment means 46 (Fig. 22) to permit theouter housing 21 to rotate the inner cap member when the inner cap member is in the untight condition about the container. Such a construction is highly effective in preventing the accidental opening of the container by a young child and provides the valuable child-proof function for a closure member in accordance with the present invention. - The combination of elements shown in Figs. 15 and 16 describe a structure which provides for the reminder function of the closure member 11, and Figs. 16 and 17, together with the abutment means 46 and the
grooves 54, describe a structure which provides the child-proof function for the closure member 11. - Still another embodiment of the present invention is illustrated in Figs. 18-21 wherein the closure member 11 is comprised of an
outer housing 21, aninner housing 41 and aninner cap member 51. Theouter housing 21 includes arecess 59 therein which is adapted to receive a removable indicia member in the form of adisc 62. Ashoulder 61 on theinner housing 41 prevents the rotation of the inner andouter housings disc 62. Although not shown, thedisc 62 includes anopening 64 therein which cooperates withprojection 65 to prevent movement of the disc with respect to theinner housing 41. Theouter housing 21 includes anopening 23 therein which cooperates with theindicia disc 62 to reveal indicia thereon. When theinner housing 41 is nested within theouter housing 21, an outwardly projectingridge 43 extends around the bottom of the cylindrical wall of theinner housing 41 to engage thebottom portion 22 of theouter housing 21 to rotatably secure the inner housing within the outer housing and to facilitate indexing of the indicia past theaperture 23 when the closure member 11 is threaded onto a closure (not shown), bythreads 55. - A plurality of
spring fingers 20 extend downwardly from the inside of theinner housing 41 and rest upon the topplanar surface 76 of theinner cap member 51. Abutment means 25, 46 (Fig. 19 and 20) extend downwardly from the inside corner of both the outer and inner housings and are engageable with complementary grooves 54 (Fig. 23) located in therim 56 of both theinner housing 41 and theinner cap member 51. The downwardly projecting abutment means 46 and thegrooves 54 are positioned in a complementary spaced manner, such that the abutment means 46 andgrooves 54 only partially mesh with each other when the outer housing is in an outward relaxed position. In this relaxed position, rotation of theouter housing 21 andinner housing 41 is ineffective to untighten theinner cap member 51 when the inner cap member is in the tight position. A downward force upon theouter housing 21 pushes downwardly theinner housing 41 and compresses thespring fingers 20 and narrows the space between theinner housing 41 and theinner cap member 51 thereby fully engaging the abutment means 46 of the inner housing with thegrooves 54 of the inner cap member, a position as shown in Fig. 23. When the abutment means 25, 46 andgrooves 54 of the outer housing, the inner housing and the inner cap member are so engaged, the inner cap member may be untightened and rotated in unison with the outer housings. When the force upon the outer housing is released, thespring fingers 20 again force theinner housing 41 upward partially disengaging the abutment means 46 from thegrooves 54. In this relaxed position, further rotation of theouter housing 21 with respect to theinner housing 41 is effective in rotating theinner cap member 51 because the inner cap member is loosely affixed to the closure. The elements shown in combination with respect to Figs. 19 and 20 illustrate a structure which provides for the reminder function of the closure member 11 and the elements shown in Figs. 20 and 21, together with the abutment means 46 and thegrooves 54, provide the child-proof function for the closure member 11. Preferably, the abutment means 46 andgrooves 54 are of a trapezoidal shape configuration, as shown in Figs. 22 and 23, which provide the unique child-proof function of the closure member 11. - As is well understood from the above disclosure, the closure member 11 includes an
inner housing 41 having abutment members thereon comprised of grooves in either the projectingrim 44 of the inner housing or positioned substantially lengthwise upon the outer horizontal wall surface thereof. As previously mentioned, these grooves, although shown in Figs. 3 to be substantially perpendicular recessed openings may be of a depressed ramp configuration, as shown in Figs. 9 and 10, or of a trapezoidal shape configuration, as shown in Figs. 22 and 23. Additionally, the abutment means 25 preferably incIudes a projection or projections extending either inwardly from the inner cylindrical wall of theouter housing 21 or inwardly and downwardly from the upper wall or corner of theouter housing 21 which engage thegrooves 42 in therim 44, a castle-like structure, or grooves in the side-wall to permit the outer housing to rotate relative to the inner housing to reveal indicia in theaperture 23 of theouter housing 21. - Also, a closure member in accordance with the present invention may be constructed to either include an inner cap member to provide child- proofing features, or include only an inner and outer housing member, as shown in Figs. 8-10 and 11-13, wherein the inner cap member includes
threads 55 thereon which permit attachment of the closure member 11 to thecontainer 12. - It will be readily seen that in any of the above- described embodiments a removable indicia means such as a disc may be mounted in a relatively fixed, stationary manner on the inner housing. Thus any set of desired indicia may be inserted without changing the fundamental structure of the cap. Thus, one molded structure can be custom adapted to any schedule at a minimum cost. At the time the medication is placed in the bottle by a manufacturer, a pharmacist, or even a patient, a disc or other insertable and removable indicia means with the appropriate schedule for that medication may be inserted.
- As shown in my previous US-A-4,220,247, the abutment means including grooves and ribs may be positioned on either the inner or outer housings. It is only sufficient that the grooves and ribs eliminate play between the inner and outer housings when the abutment means are engaged, yet permit the inner and outer housings to yieldingly rotate relative to each other in one direction and are effective to stop the relative rotation of the inner and outer housings in the opposite direction, while predeterminedly controlling the positioning of the indicia disc mounted in the inner housing with respect to the opening in the outer housing to convey information to the patient and user.
- It is also within the scope of the present invention to include an outer housing structure having an indicator viewing station or means which cooperates with the indicia means on the inner housing to indicate the desired indicia. For example, the outer housing may be composed of a transparent plastic material and include arrow means thereon which indicate the desired indicia. Also, it is within the scope of the present invention that the length, of the side wall of the outer housing may be less than the length of the side wall of the inner housing such that the indicia on the inner housing may be exposed to cooperate with indicator viewing means on the side wall of the outer housing.
