Large capacity pill bottle with improved child resistance

Large capacity pill bottle with improved child resistance description/claims

This continuation-in-part application claims priority from, and the benefit of U.S. patent application Ser. No. 11/693,452, filed Mar. 29, 2007, which itself claimed priority from U.S. Provisional Patent application Ser. No. 60/885,732, filed Jan. 19, 2007, and entitled Pill Bottle, the entirety of which application is incorporated by reference herein.

The present invention generally relates to bottles suitable for dispensing medications and, more particularly to a pill bottle that provides senior-friendly access while meeting the standards for child-resistant entry, and that also provides for improved compound stability during shipment, storage, and dispensing of the medication.

It is well known that medications, e.g., pills, tablets, and capsules must often be dispensed over a prescribed number of consecutive days. In addition, it is also known that such medication dispensers are required by law to be child-resistant while at the same time being relatively easily opened by an elderly or infirm person. Child-resistant containers are known, such as screw-top bottles and flip-top bottles with locking mechanisms. These prior art bottles are often difficult for the elderly to open due to their diminishing manual dexterity. A traditional “amber” bottle closed by a child resistant mechanism incorporated into its cap or top of the bottle has been developed for the dispensing of medication in pill form. These prior art pill bottles suffer from many problems.

A prior art amber bottle typically poses a nuisance for a user of limited dexterity. Often when using such prior art bottles, multiple pills will be handled and put back into the bottle because of difficulty in selecting one pill at a time. This inevitably leads to contamination of the remainder of the pills in the bottle from hand moisture or body oils, often leading to decreased effective shelf-life of the medication. Thus, these bottle often did not address completely or cure the issue of stability/integrity of the medication. Also, with a traditional amber bottle the user does not get any feedback as to whether or not a correct dose has been taken.

Blister packs, often referred to as “unit dosing” packages, are also well known as offering a solution to some of the foregoing problems. They are typically formed of polymers or other flexible materials with a plurality of depressions or blisters that each receive and dispense a pill or capsule. One side of a conventional blister pack is covered with a foil material to seal and secure the pill or capsule in place and so as to provide for compound stability during storage. When finger pressure is applied against a convex portion of the blister, the capsule breaks through the foil material thereby releasing it for consumption. The blister pack often ensured the stability of the medication by isolating and sealing the pill in a single compartment. Unfortunately, blister packs do not provide an adequate child-resistant dispenser. Also, the elderly user may have difficulty releasing the medication from the dispenser in the prescribed manner as a result of diminished finger strength or flexibility.

In U.S. Pat. No. 3,809,221, issued to Compere, a rupturable press-through blister type medicament or pill package is “childproofed” by securing a strong flexible polymeric backing sheet, such as polyethylene terephthalate, over the rupturable sheet. This backing sheet ensures that the pill cannot be forced through the package unless the backing sheet is first peeled off. Here again, the elderly user may have difficulty releasing the medication from the package in the prescribed manner as a result of diminished finger strength.

The present invention provides a senior-friendly, child-resistant pill bottle that includes a first annular wall disposed within an interior portion of the bottle. The first annular wall has an outer surface with a plurality of circumferentially spaced, vertically oriented protrusions that project radially outwardly from that surface. A second annular wall is disposed within the interior portion of the bottle in enclosing relation to the first annular wall. The outer and inner surface of the second annular wall undulate so as to define a series of troughs and ridges. Advantageously, an adjacent pair of the protrusions is located in spaced confronting relation to each of the troughs formed by the undulating surface of the second annular wall so as to define a plurality of pill wells. In this way, each pill may be arranged and oriented so as to be “on-end” or “on-edge” within the bottle.

In another embodiment, a pill bottle is provided that includes an annular wall disposed within an interior portion of the bottle that has an outer surface with a plurality of circumferentially spaced, vertically oriented ribs that project outwardly from the outer surface. An annular divider is disposed within an interior portion of the bottle in enclosing relation to the annular wall. The annular divider has an outer surface and an inner surface that undulate so as to define a series of troughs and ridges wherein an adjacent pair of the ribs is located in spaced confronting relation to each of the troughs so as to define a plurality of pill wells thereby allowing each pill to be stored resting upon a tip. A rotatable dial closure is disposed in overlying relation to the pill wells that defines a chimney through which successive ones of the pills are delivered upon incremental rotation of the dial closure. A removable closure is disposed in overlying relation to the rotatable dial closure.

In a further embodiment, a pill bottle is provided that includes a first annular wall disposed within an interior portion of the bottle that has an outer surface with a plurality of circumferentially spaced, vertically oriented ribs that project outwardly from the outer surface. A second annular wall is disposed within an interior portion of the bottle in enclosing relation to the first annular wall. The second annular wall has an outer surface and an inner surface that undulate so as to define series of troughs and ridges. An adjacent pair of the ribs is located in spaced confronting relation to each of the troughs so as to define a plurality of pill wells thereby allowing each pill to be stored resting upon a tip. A rotatable dial closure is disposed in overlying relation to the pill wells. The rotatable dial closure defines a chimney through which successive ones of the pills are delivered upon incremental rotation of the dial closure. The rotatable dial closure also includes a dosage-counter disk positioned on a dosage-counter snap tube so that it may be selectively and incrementally rotated when the dial closure is incrementally rotated so as to display an indicia within a counter window so that a patient may determine whether they have taken their medication on any given day.

In a yet further embodiment of the invention, a pill bottle is provided that includes a pill carriage with a first annular wall disposed within an interior portion of the pill carriage. The first annular wall includes an outer surface with a plurality of circumferentially spaced, vertically oriented ribs that project outwardly from the outer surface. A second annular wall is disposed within an interior portion of the pill carriage in enclosing relation to the first annular wall, and has a outer surface and an inner surface that undulate so as to define a series of troughs and ridges. An adjacent pair of the ribs is located in spaced confronting relation to each of the troughs so as to define a plurality of pill wells thereby allowing a pill to be stored within one of the pill wells resting upon at least one of a tip and an edge. An internal annular wall includes an outer surface with a plurality of circumferentially spaced, vertically oriented protrusions that project outwardly from the outer surface. A base cap is also provided that has a bottom wall with a peripheral edge and an annular wall projecting from the peripheral edge so as to define a receptacle space. In this way, the pill carriage is received within the receptacle space, with the plurality of pill wells being selectively accessible.

In another embodiment of the invention, a pill bottle is provided that includes a pill carriage with a first annular wall disposed within an interior portion of the pill carriage. The first annular wall includes an outer surface with a plurality of circumferentially spaced, vertically oriented ribs that project outwardly from the outer surface. A second annular wall is disposed within an interior portion of the pill carriage in enclosing relation to the first annular wall, and has a outer surface and an inner surface that undulate so as to define a series of troughs and ridges. An adjacent pair of the ribs is located in spaced confronting relation to each of the troughs so as to define a plurality of pill wells thereby allowing a pill to be stored within one of the pill wells resting upon at least one of a tip and an edge. An internal annular wall includes an outer surface with a plurality of circumferentially spaced, vertically oriented protrusions that project outwardly from the outer surface. A base cap is also provided that has a bottom wall with a peripheral edge and an annular wall projecting from the peripheral edge so as to define a receptacle space. In this way, the pill carriage is received within the receptacle space, with the plurality of pill wells being selectively accessible. A closure a cap is provided that is integrally connected to the pill carriage base with at least one living hinge.
