This invention relates generally to pharmaceutical dispensers and, more particularly, to a dispenser that stores and dispenses orally dissolvable strips.
For many years, most prescription and over-the-counter medications have been dispensed in pill or liquid form. Pill medication, of course, is typically dispensed in bottles although it may also be dispensed in foil packages. More recently, however, pharmaceuticals have been provided in the form of orally dissolvable strips. Each thin strip dissolves very quickly on a consumer's tongue and is then absorbed into the body.
Orally dissolvable strips have typically been dispensed as a stack of strips packaged in a box, each medicinal strip being sandwiched between thin strips of plastic so as to maintain purity and to keep the strips from sticking to one another. Although assumably effective for their intended use, the traditional packaging of orally dissolvable medicine strips requires a user first separate one strip from others in a stack, peel the plastic separator strips away from a respective medicine strip, and then to dispose of the separate films. Another disadvantage of dispensing pharmaceuticals, whether pills or orally dissolvable strips, is that a patient may require a multitude of different medicaments multiple times a day. Each time, many bottles or many strips must be opened or dispensed, requiring valuable time and introducing the potential for errors to be made.
Therefore, it would be desirable to have a dispenser for delivering orally dissolvable strips. Further, it would be desirable to have a dispenser that automatically separates a medicine strip from the plastic separator strips as the medicine strip is dispensed. In addition, it would be desirable to have a dispenser that collects the separator strips after they have been separated from the medicine strip and the medicine strip has been dispensed. Still further, it would be desirable to have a dispenser the enables multiple dispensers to be operatively connected in a manner enabling strips from multiple dispensers to be dispensed simultaneously and with the operation of only a single input element.
A dispenser for an orally dissolvable strip includes a pair of receiving spools for receiving respective layers of wrap material that sandwich the orally dissolvable strip. A rotatable knob is coupled to the spools for actuating the spools. A force transfer apparatus is configured to rotate the second spool when the first spool rotates. A housing contains the receiving spools, force transfer apparatus, orally dissolvable strip, and layers of wrap material, the housing having a slot sized for the dissolvable strip to pass through. A coupling element is connected to a housing side wall configured connect the housing laterally to another housing side wall. A channel extends between a knob input aperture and a housing rear plate output channel. A drive shaft is positioned in the channel and configured to extend from the output channel and operatively couple the rotatable knob with a rotatable knob of another dispenser.
Therefore, a general object of this invention is to provide a dispenser for selectively dispensing an orally dissolvable medicine strip.
Another object of this invention is to provide a dispenser, as aforesaid, that separates the medicine strip from the wrapping strips between which the medicine strip is sandwiched.
Still another object of this invention is to provide a dispenser, as aforesaid, that collects the wrapping strips for later disposal.
Yet another object of this invention is to provide a dispenser, as aforesaid, in which all components are held within a protective housing.
A further object of this invention is to provide a dispenser, as aforesaid, that is cost-effective and user-friendly.
A particular object of this invention is to provide a dispenser, as aforesaid, that may be coupled laterally to another dispenser in a side-by-side configuration;
Another particular object of this invention is to provide a dispenser, as aforesaid, having structures such that two or more dispensers may be coupled in a front to back configuration and actuated to dispense respective orally disposable strips upon actuation only of the first dispenser.
Other objects and advantages of the present invention will become apparent from the following description taken in connection with the accompanying drawings, wherein is set forth by way of illustration and example, embodiments of this invention.

A dispensing apparatus will now be described in detail with reference to
As shown in
As shown in
The dispenser 10 includes a housing 120 having opposed front 121a and rear 121b plates with opposed side walls 123 connecting the front 121a and rear 121b plates. As shown in the drawings, the side walls may include a rounded configuration; however, it is understood that the side walls may be substantially planar and in such case the housing 120 may also include opposed top and bottom walls. Together, the plates and walls of the housing 120 define an interior area configured to contain the receiving spools 110a, 110b, the orally dissolvable strip 10, the layers of wrap material 15a, 15b, and the force transfer apparatus 116. The housing 120 has a slot 122 sized for the orally dissolvable strip 10 to pass through (
First and second guide rollers 130a, 130b (
In use, the user opens the cap 125 (
As shown in
The dispenser may be discarded after the orally dissolvable strip 10 is entirely removed from the housing 120, or the housing 120 may be reusable. For example, a cassette holding the orally dissolvable strip 10, the layers of wrap material 15a, 15b, the first and second receiving spools 110a, 110b, and the first and second guide rollers 130a, 130b may be replaceable by opening the housing 120.
Another embodiment of a dispenser 200 is shown in
As shown in
The alternative embodiment of the dispenser 200 may further include a spacer plate 240 having a configuration that enables multiple dispensers to be coupled together in a front-to-back configuration for simultaneous operation. As shown particularly in
In some embodiments (not shown), it is contemplated that the rear plate 230 of the housing 120 may also be configured in a manner consistent with that of the spacer plate 240 and, therefore, serve unitarily as both the rear plate 230 of the housing 120 as first described in this specification and as the spacer plate 240.
A transfer drive shaft 250 extends through the channel 224 and associated input 222 and output 232 apertures. The transfer drive shaft 250 is operatively connected to the rotatable knob 114 of a dispenser 200 and is rotated when the knob 114 is rotated. The transfer drive shaft 250 includes a length such that it may extend outwardly from the output aperture 232 of one housing 120, through the spacer plate aperture 241, and into the input aperture 222 of another dispenser housing 120 such that the transfer drive shaft 250 is in operative engagement with the rotatable knob 114 of the another housing 120. Stated another way, the transfer drive shaft 250 of a “first” dispenser may extend away therefrom into operative engagement with a “second” dispenser. Accordingly, an operation of the rotatable knob 114 of the first dispenser causes a simultaneous and equal rotation of the rotatable knob 114 of the second or “another” dispenser.
In the embodiment described immediately above, the transfer drive shaft 250 that connects the rotatable transfer knob of two dispensers causes rotation thereof to rotate at the same speed, i.e. the same amount of rotation. From a practical viewpoint, rotation of the rotatable knob 114 of a first dispenser causes the same amount of a dissolvable strip 10 to be dispensed through the housing slot 122 of the first and second dispensers to which the transfer drive shaft 250 is interconnected as described above. However, the dispenser 200 according to the alternative embodiment disclosed herein may further include a gear modification assembly 260 that is operatively connected or coupled to the distal end 252 of the transfer drive shaft 250 and is also operatively connected or coupled to the input end 254 of the transfer drive shaft of another transfer drive shaft of another dispenser. In other words, the gear modification assembly 260 is situated between the end of a transfer drive shaft 250 extending outwardly from one dispenser and its engagement with the input aperture 222 and channel 224 of another or “second” dispenser.
The gear modification assembly 260 includes components and configuration that causes the transfer drive shaft 250 of “another” or “second” dispenser to rotate at a speed different than that of the transfer drive shaft 250 of the initial, first, or original dispenser 200. The gear modification assembly 260 may be configured such that a transfer drive shaft 250 of the so-called “another” or second dispenser to rotate more slowly or more quickly. From a practical viewpoint, the subsequent dispenser may dispense more or less of the dissolvable strip 10 than that dispensed by the first dispenser 200 as a result of the configuration of the gear modification assembly 260. As shown in
More particularly the gear modification assembly 260 may include an input drive cam 262 coupled to the distal end 252 of the transfer drive shaft 250, the cam 262 then being operatively coupled to an intermittent motion gear 264 (
The dispenser 200 according to the alternative embodiment of the present invention may also include a cutting member 212 to aid a user in tearing or severing a desired amount of the dissolvable strip 10. More particularly, the cutting member 212 may be positioned on an exterior of the housing 120 immediately adjacent the housing slot 122 (
In use, the normal function of the dispenser 200 is as first described above so as to dispense orally dissolvable strips, such as for dispensing pharmaceutical substances. The embodiment immediately described above, provides a unique structure for not only coupling two or more dispensers together in a lateral or side-by-side configuration, but to coupling two or more dispensers together in a front-to-back configuration and with a structure that allows multiple dispensers to be actuated together with a single operation of the rotatable knob 114 of the front-most dispenser. The transfer drive shaft 250 coupled to the rotatable knob 114 extends through the output aperture 232 of the dispenser housing 120 and through the spacer plate aperture 241 and into engagement with the input aperture 222 and rotatable knob 114 of another or second dispenser. It is understood that this configuration may be repeated with multiple dispensers being coupled together. A rotation of the rotatable knob 114 actuates the spools contained in the housing 120 to dispense a medicine strip 10 as described above. The rotation of the rotatable knob 114 also causes the transfer drive shaft 250 to rotate/actuate a coupled next dispenser(s). Accordingly, dissolvable strips from all of the coupled dispensers are dispensed simultaneously without individual operation of each separate dispenser. In embodiments including a gear modification assembly 260, the dispensers coupled to the first/front dispenser may dispense more or less dissolvable strips, depending on the configuration.
Accordingly, it can be seen that embodiment of the invention described immediately above provides a convenience never before known or disclosed regarding dispensers of orally dissolvable medicine strips or any other type of dispensers. In this way, a patient is able to manage the dispensing of multiple types and quantities of medicine with a single rotation of a front-most dispenser.
It is understood that while certain forms of this invention have been illustrated and described, it is not limited thereto except insofar as such limitations are included in the following claims and allowable functional equivalents thereof.
