Patent Application
20130102989
Virtually everyone consumes prescription pharmaceuticals at one time or another. A large number of prescription pharmaceuticals are for liquid medications, especially in the area of pediatrics. Pouring and measuring individual doses of liquid medications has long been a less than precise task prone to spilling or waste of the liquid medication or other messy interactions. As such, oral or needleless syringes have been developed to provide cleaner and more accurate means for measuring individual doses of liquid medication.
To provide for selective reception of needleless syringes in a substantially airtight manner, adapters are typically placed in medication containment vessels, such as bottles, to limit the size of an opening providing access to the liquid medication while still enabling a tip or nozzle of the needleless syringe to be connected in fluid communication with an interior of the bottle and the liquid medicine contained therein. Improvements in adapters are desired that both contribute to increased accuracy in measuring individual dosages of medicine, lessened amounts of wasted or inadvertently dispensed liquid medicine, and address other shortcoming of conventional bottle adapters.
One embodiment of the invention relates to a dispensing insert configured to friction fit within a neck of a bottle and to selectively receive an oral syringe. The dispensing insert includes a hollow cylinder, a top plate capping one end of the hollow cylinder, a raised deck extending substantially parallel to and spaced from the top plate, and an annular side wall extending from the top plate upwardly toward the raised deck. The raised deck has a smaller outer diameter than the top plate and defines an opening therethrough configured to provide access to contents of the pharmacy bottle through the dispensing insert. The annular sidewall substantially encompasses an outer perimeter of the raised deck. Other dispensing inserts, associated medicine dispensing containment systems, and associated methods are also described herein.
Embodiments of the invention will be described with respect to the figures, in which like reference numerals denote like elements, and in which:
In the following detailed description, reference is made to the accompanying drawings, which form a part hereof, and in which are shown by way of illustration specific embodiments in which the invention may be practiced. The following detailed description, therefore, is not to be taken in a limiting sense, and the scope of the present invention is defined by the appended claims.
Referring to
In one embodiment, body 20 includes a front panel 30, a rear panel 32, side panels 34, and a spine or bottom panel 36. Front panel 30 is positioned opposite rear panel 32, and one of side panels 34 extends between front panel 30 and rear panel 32 on either side of bottle 12 to define storage chamber 22 therebetween. Accordingly, body 20 is one example of means for containing liquid medicine 28. Bottom panel 36 extends between front panel 30, rear panel 32, and side panels 34 to enclose an end of bottle 12. In one embodiment, bottom panel 36 is substantially planar such that bottle 12 can be placed with bottom panel 36 on a support surface (not shown) such that bottle 12 is supported by and extends upwardly from bottom panel 36.
Neck 24 extends away from a portion of bottle 12 opposite bottle panel 36 to form an end of bottle 12 opposite bottom panel 36. In one embodiment, body 20 of bottle 12 defines shoulders 38 extending and tapering from front panel 30, rear panel 32, and side panels 34 to neck 24 opposite bottom panel 36. Neck 24 defines opening 26 opposite body 20 adjacent a topmost edge of neck 24, and opening 26 provides access to storage chamber 22 permitting liquid medicine 28 to be placed in and be removed from storage chamber 22 via opening 26. In one embodiment, neck 24 is threaded, e.g., double threaded, and defines opening 26 opposite body 20 providing access through neck 24 to storage chamber 22 such that threads 44 of neck 24 are configured to threadably receive an appropriate closure, such as a closure 126 (
In one embodiment, front panel 30 and rear panel 32 of body 20 each define a substantially planar outer surface 40 and 42, respectively, that are each substantially rectangularly shaped, thereby defining a generally flat, broad surface especially suited for reading information on portions of a label (not shown) applied thereto (e.g., a label similar to that described in U.S. Pat. No. 7,311,205, filed Jan. 25, 2005, and issued Dec. 25, 2007, which is incorporated herein by reference). For example, substantially planar surfaces 40 and 42 enable display of label information in a manner in which all of the information printed on a portion of a label applied to each of substantially planar surfaces 40 and 42 can be read generally without turning or rotating bottle 12.
In one example, the relatively broad nature of substantially planar surfaces 40 and 42 of front panel 30 and rear panel 32 of container 20 enable bottle 12 to be set down on its side onto a support surface without bottle 12 rolling along the support surface. In particular, the breadth and relative flatness of front panel 30 or rear panel 32 prevent rolling of bottle 12 when either one of front panel 30 or rear panel 32 are placed directly on the support surface.
Continuing to refer to
In one embodiment, recess 48 is configured to selectively maintain an information card (not shown), such as a folded information card, and allow the information card to selectively slide into and out of recess 48 via the side opening at outer edge 56. To facilitate the maintenance of the information card in recess 48, in one example, a bottle label (not shown) is positioned to extend over and be adhered to substantially planar surface 42 around (e.g., on three sides of) recess in a manner remaining spaced from recess surface 57 as described in U.S. Pat. No. 7,311,205, which was incorporated by reference above. In such an embodiment, inner edge 54 of recess 48 is configured to prevent further sliding movement of an information card laterally inward into recess 48, and upper edge 50 and lower edge 52 of recess 48 define guides to help maintain lateral motion of the information card in and out of recess 48, and to maintain the information card within recess 48.
Substantially planar exterior surfaces 40 and 42 each curve outwardly (i.e., away from each other) at top portions 44 and 46, respectively, adjacent shoulders 38 in one embodiment. As such, an overall width of body 20 gradually increases beyond a largest width of each corresponding side panel 34. This increase in width is advantageous to allow for easy movement of medicine 28 toward neck 24 and opening 26, for example, for dispensing medicine 28 using needleless syringe 180 (
In one embodiment, front panel 30 and rear panel 32 are generally symmetric with each other regarding a size and general shape (e.g., substantially rectangularly shaped) and side panels 34 are generally symmetric with each other regarding a size and general shape (e.g., substantially rectangular or alternatively substantially trapezoidally shaped). In another embodiment, front panel 30 and rear panel 32 are generally asymmetric with each other regarding a size or a general shape and side panels 34 are generally asymmetric with each other regarding a size or a general shape.
In one embodiment, one or both of side panels 34 includes graduation demarcations 58. For example, graduation demarcations 58 extend up at least one of side panels 34 and are formed to outwardly protrude from the respective at least one of side panels 34 as indicated in
Turning back to a top portion of bottle 12, in one embodiment, shoulders 38, which extend inwardly from each of front panel 30, rear panel 32, and side panels 34 to a centrally located neck 24, taper inwardly to meet an exterior neck surface 80 of neck 24. Neck 24 extends upwardly from shoulder 38 to define opening 26 opposite shoulder 38 at a topmost edge of neck 24. Opening 26 provides access to storage chamber 22 through neck 24. Neck 24 additionally defines an interior neck surface 82, which is substantially smooth, in one embodiment. Where neck 24 is threaded to receive a closure, such as closure 126, threads 84 extend circumferentially around exterior neck surface 80. In one embodiment, two sets of opposing threads 84 are used to allow closure 126 to be tightly held over neck 24 without requiring excessive rotation of closure 126.
Interior surface 82 of neck 24 defines an inner shelf or inner ledge 86 near opening 18, according to one embodiment. Inner ledge 86 is formed by a thinning of the overall material thickness of neck 24 at inner ledge 86 and above (i.e., toward an opening 26 of bottle 12). As such, inner ledge 86 is annular and defines a topmost surface 88. Inner ledge 86 is configured to interface with dispensing insert 14 to provide for secure and accurate placement of dispensing insert 14 within neck 24 as will be further described below. Inner ledge 86 is one example of means for recessing dispensing insert 14 in neck 24.
In one embodiment, ledges or wings 90 extend radially outwardly from exterior neck surface 80 from positions vertically closer to shoulder 38 than opening 26. For example, each of two wings 90 extend from exterior neck surface 80 radially outwardly in a different direction toward a different one of side panels 34. Each wing 90 is fairly broad and flat in nature. In one embodiment, each wing 90 has a width measured from exterior neck surface 80 to an free end of each wing 90 of at least about 30% of, more preferably, at least about 40%, a outside diameter of neck 24. In one example, a width measured from an outermost edge of one of wings 90 to an outermost edge of the other of one of wings 90 is equal to at least about 75%, more preferably, at least about 85%, a width of the shoulder 38 or overall width of body 20 as a whole and/or at least about 130%, more preferably, at least about 140%, a width or outer diameter of neck 24.
In one example, each wing 90 includes a ramped protrusion 92 extending upwardly from a top surface of each wing 90. For instance, referring to
In one embodiment, dispensing insert 14 additionally includes a top panel or top plate 104, a raised deck 106, and a sidewall 108 such as an annular and tapered protrusion from top plate 104 to raised deck 106. Top plate 104 is substantially planar and positioned above and parallel to annular rims 102. However, top plate 104 is formed thicker or otherwise formed to be substantially more rigid than annular rims 102 such that top plate 104 generally does not readily bend due to interaction with interior surface 82 of neck 24. In one embodiment, an outer diameter of top plate 104 is sized substantially identically (in one example, slightly smaller than) a diameter of interior surface 82 of neck 24 just above inner ledge 86 and larger than a diameter of interior surface 82 of neck 24 below inner ledge 86.
In one embodiment, raised deck 106, which is substantially planar, is spaced above, extends substantially parallel to, and is coaxially positioned relative to top plate 104. In one example, raised deck 106 extends above top plate 104 a distance more than about twice, in one embodiment, a distance more than three times, a thickness of top plate 104. Raised deck 106 is shaped similarly to (e.g., circular), but has an outer diameter sized smaller than (e.g., less than about 60% of the diameter of, and in one embodiment, less than about 50% the diameter of) top plate 104. Sidewall 108 extends from an internal position of top plate 104 (i.e., a position spaced radially inwardly from an outer or peripheral edge of top plate 104) to an outer periphery of raised deck 106, for example, in a manner tapering inwardly to raised deck 106. In one example, top plate 104 is open inside sidewall 108. Sidewall 108 extends upwardly beyond raised deck 106, to define a rim 112 around raised deck 106 according to one embodiment, thereby defining a depressed top area 114 above raised deck 106 and inside and below a top edge of rim 112.
An aperture or opening 116 is defined through raised deck 106 to provide access to storage chamber 22 of bottle 12 through dispensing insert 14. In one example, a skirt 118 extends from opening 116 downwardly at least partially through a center of dispensing insert 14 (see, e.g., the cross section of
When a pharmacist or other suitable individual is filling a prescription for liquid medicine 28 that will utilize needleless syringe 180 (
In pushing dispensing insert 14 into neck 24, annular rims 102 bend slightly upwardly as they tightly interface with and slide along interior surface 82 of neck 24. In this manner, each annular rim 102 tightly presses against interior surface 82 of neck 24 forming a seal to substantially prevent any flow of liquid medicine along interior surface 82 of neck 24 toward opening 26. As such, the plurality of annular rims 102 provides multiple seals or barriers substantially stopping medicine 28 from inadvertently leaking out of bottle 12 around dispensing insert 14 and substantially decreasing air entering bottle 12 around dispensing insert 14 during dispensing of medicine 28 from bottle 12. In one embodiment, where annular rims 102 are not included, cylindrical body 100 bows outwardly to tightly interface with interior surface 82 of neck to provide at least one barrier for medicine 28 to escape through neck 24 around edges of dispensing insert 14, as will be apparent to one of skill in the art upon reading this application.
Once bottle 12 and dispensing insert 14 are coupled to one another, rim 112 is positioned to be substantially at the same level or on the same plane as or lower than a topmost edge of neck 24. In this manner, voids 120 are defined between interior surface 82 of neck 24 and sidewall 108 as best shown in
In one embodiment, in preparing an associated prescription, the pharmacist or other suitable individual also places a ring 128 around neck 24. In one embodiment, a plurality of rings 128 each having substantially identical structure, but a different coloring, external surface ornamentation, or other external visual differentiator are available to the pharmacist or other suitable individual preparing a prescription. During prescription preparation, one of the rings 128 is chosen having an external visual differentiator that is assigned to the patient receiving the prescription (either at the time the prescription is filled or prior). In one embodiment, the different ones of rings 128, for example, rings 128 that are each substantially identical other than coloring, surface ornamentation, etc. are configured to visually associate each corresponding bottle assembly with a family or household member. More particularly, in one example, each family member or household member is assigned a color or surface ornamentation associated with one of rings 128. Each time the respective family or household member has a prescription filled, one of rings 128 with the same colored or surface ornamentation is used on a corresponding one of bottles 12 readily visually associating each of the bottles 12 with the appropriate family or household member. In view of the above, any of rings 128 with associated color and/or surface ornamentation are means for visually associating the bottle with a patient who was prescribed a corresponding medication in comparison to other members of the family or household of the patient.
In one embodiment, each ring 128 is formed of substantially rigid, yet slightly flexible material, such as a non-elastomeric plastic or similar material, and is configured to fit around neck 24 of container 20, more specifically, to rest above shoulder 38 and sit just below wings 90 (see
In one example, closure 126 additionally includes an inner protruding ring 146 and an outer protruding ring 148 both protruding downwardly from interior surface 138 of top panel 130 inside inner skirt 132. Inner protruding ring 146 and outer protruding ring 148 are configured to interface with dispensing insert 14 to assist in housing and dispensing liquid medications 28 in a liquid-tight manner as further described below.
Outer skirt 134 extends downwardly from the outermost perimeter of top panel 130, in one example, with a slight outward flare. A bottom-most edge of outer skirt 134 has an outer perimeter, at least along front and back portions, which is configured to extend substantially coterminous with an outer perimeter of ring 128, according to one embodiment. Outer skirt 134 includes an outer surface 150, an inner surface 152 opposite outer surface 150, and a bottom edge 153 (
Outer skirt 134, in one embodiment, includes opposing grip sections 156 on opposite sides of outer skirt 134 coupled to a remainder of outer skirt 134 on each side by a transitional section 157, which is substantially thinner than a remainder of outer skirt 134. The thin transitional section 157 permits deflection of opposing grip sections 156 relative to the rest of outer skirt 134 when external force (i.e., pinching by a user) squeezes the opposing grip sections 156 toward one another. In one embodiment, grip sections 156 are configured with various features facilitating a user in gripping and squeezing the appropriate portions of closure 126. In one example, closure 126 additionally includes raised indicia 158 protruding slightly upwardly from exterior surface 136 of top panel 130 and providing instructions to a user for interacting with closure 126. For example, raised indicia 158 may include text and graphic indications instructing a user to squeeze grip sections 156 and turn closure 126 to remove closure 126 from the respective bottle 12 to open bottle 12 and access its contents.
In one example, closure 126 includes additional features positioned between inner skirt 132 and outer skirt 134 to establish closure 126 as being child-resistant. In one embodiment, the additional features of closure 126 include ramp protrusion 160 and stops 162. One of ramp protrusions 160 is positioned to extend into void 154 from inner surface 152 of outer skirt 134 and extends downwardly below bottom edge 190 of inner surface 152. Ramped protrusions 160 are angled and configured to interface with ramped protrusion 92 of bottle such that each ramped protrusion 160 easily slides over and past a corresponding ramped protrusion 92 of bottle 12 when closure 126 is turned clockwise due to the angles of ramped protrusions 92 and 160. The same angles of ramped protrusions 92 and 160 make it substantially difficult, i.e., near impossible for a child, to turn closure 126 counterclockwise to move ramped protrusions 160 back over and past ramped protrusion 92 to remove closure 126 from bottle 12.
One of stops 162 is positioned to extend inwardly from inner surface 152 of outer skirt 134, more specifically, grip sections 156 of outer skirt 134, spaced just slightly from trailing end of each ramped protrusion 160. Each stop 162 is configured to interface with one of ramped protrusions 92 of bottle 12 to prevent over-rotation or tightening of closure 26 relative to neck 24 of bottle 12 and extends below a bottom edge of inner skirt 132.
When properly fitted on bottle 12, as described above, closure 126 also interfaces with interior surface 82 of neck 24 and dispensing insert 14 to seal off opening 26 during storage or non-use. More specifically, referring to
At 206, liquid medicine 28 is poured or otherwise dispensed into bottle 12. Subsequently, at 208, dispensing insert 14 is substantially coaxially aligned with opening 26 in neck 24 and is inserted and pushed down into neck 24 until a bottom surface of top plate 104 of dispensing insert 14 interfaces with top surface 88 of inner ledge 86 of neck 24 as shown in
At 210, closure 126 is secured to bottle 12 in a manner interacting with both bottle 12 and dispensing insert 14 to effectively seal opening 26. In one example threads 144 of closure 126 are spun around threads 84 of neck 24 to secure closure 126 to neck 124. When fully closed and properly positioned, inner protruding ring 146 of closure 126 directly interfaces with opening 26 and/or skirt 118 to provide a first barrier to inadvertent escape of liquid medicine 28 from bottle 12, rim 112 around raised deck 106 of dispensing insert 14 interfaces with top panel 130 of closure 126 to form a second barrier to inadvertent escape of liquid medicine 28 from bottle 12, and outer protruding ring 148 interfaces with both interior surface 82 of neck 24 and top surface of top plate 104 of dispensing insert 14 to form a third barrier to inadvertent escape of liquid medicine 28. The above-described barriers also decrease the amount of air or other contaminants entering bottle 12 from the environment, thereby increasing the viable lifespan of liquid medicine 28 contained therein. Once closure 126 is secured at 210, bottle 12 with liquid medicine 28 is presented or delivered to the patient for use.
At 226, bottle 12 and needleless syringe 180 are collectively inverted as illustrated in
