Embodiments of the invention relate generally to pharmaceutical packaging and, more particularly, relate to pharmaceutical packages having a twistable actuator for facilitating access to the medication within the package as well as related methods for accessing medications within a pharmaceutical package.
A variety of different pharmaceutical packages have been developed in order to store and control access to medication. For example, blister packaging has been developed in which one or more blisters are carried by a card with each blister housing a predefined quantity of medication, such as a pill, capsule or the like. In order to access the medication, a user may peel back a backing material so as to gain access to the interior of the blister and retrieve the medication. By storing the medication in one or more blisters carried by a card, a visible indication is provided to the user as to the amount of medication that remains available. In some instances, the predefined quantity of medication that is stored in a blister constitutes a unit dose, thereby facilitating administration of a proper dosage.
Pharmaceutical packaging must not only store and control access to medication, but at least some pharmaceutical packaging must also be child resistant in order to reduce the likelihood of inadvertent access of the medication by a child. As such, a pharmaceutical package that includes a card that carries one or more blisters for storing medication may also include a housing within which the card may be disposed. In this regard, the housing may be sized such that the card or at least that portion of the card that carries the blisters with medication therein may be slid into the housing and disposed therewithin such that the medication is not accessible while the card is disposed within the housing. In order to access the medication, the card may be slid or extended from the housing. In order to provide child resistance, the housing may therefore releasably secure the card therewithin such that the card cannot be freely slid or extended from the housing, such as by a child. Instead, the housing may be designed such that a user must squeeze or otherwise apply force to certain predetermined portions of the housing in order to release the card and to permit the card to be extended from the housing in order to access the medication. In one example, the opposite side edges of the housing must be squeezed toward one another in order to release the card.
While effective with respect to increasing the child resistance of the pharmaceutical package, these techniques which rely upon the application of force, such as a squeezing motion, to predefined portions of the housing in order to release the card from the housing, may be difficult not only for children, but also for other users, such as users having arthritis or other limitations upon the mobility of the user's fingers. Indeed, these pharmaceutical packages not only require the application of force, such as a squeezing motion, to predefined portions of the housing that may be spaced fairly widely from one another, such as approximately four inches apart from one another, but also require the user to pull or slide the card from the housing while continuing to apply the force to the predefined portions of the housing.
While the significant amount of coordinated mobility that is required to access the medication within such pharmaceutical packages is helpful in terms of increasing its child resistance, such requirements may also limit or otherwise make it difficult the access to the medication within such pharmaceutical packages by users having arthritis or otherwise having limited mobility with their hands. As such, it may be advantageous to provide an improved pharmaceutical package that continues to be child resistant, while also being more readily accessible to users including, for example, users having arthritis or other conditions that may limit the mobility of their hands.
A pharmaceutical package is therefore provided according to one embodiment of the present invention that is child resistant, but is easier to access for users having arthritis or otherwise having limited mobility in their fingers. In this regard, the pharmaceutical package of one embodiment may include a twistable actuator that may be twisted by a user in order to release a card carrying the medication from the housing. By relying upon a twistable actuator to release the card, a user having arthritis or otherwise having limited mobility in their fingers may more readily and naturally rotate the twistable actuator in order to release the card in comparison to prior pharmaceutical packages that require opposing or other predefined portions of the housing to be squeezed or that required force to otherwise be applied to certain predefined portions of the housing in order to release the card. As such, a pharmaceutical package according to one embodiment may provide for controlled access to the medication including, for example, controlled access by users having arthritis or otherwise having limited mobility in their fingers. A corresponding method of providing controlled access to the medication within a pharmaceutical package is also provided in accordance with another embodiment of the present invention.
A pharmaceutical package is provided according to one embodiment that includes a housing and a card carrying at least one medication that is slidably disposed at least partially within the housing such that the at least one medication carried by the card is positioned within the housing. For example, the card may include a plurality of blisters configured to store respective unit does medications. The pharmaceutical package of this embodiment also includes an engagement member configured to engage the card in an instance in which the card is disposed at least partially within the housing. For example, the card may define an opening and the engagement member may be configured to extend into the opening defined by the card in the instance in which the card is disposed at least partially within the housing. The pharmaceutical package of this embodiment also includes a twistable actuator configured to disengage the card and the engagement member in response to rotation of the twistable actuator relative to the housing. As noted above, the rotation of the twistable actuator may be more readily performed by a user having arthritis or otherwise having more limited mobility in their fingers.
In one embodiment, the engagement member includes a pin. In this embodiment, the twistable actuator may be threadably connected to the pin such that rotation of the twistable actuator retracts the pin from the opening so as to permit the card to be slidably extended from the housing. The twistable actuator of this embodiment may also include a bias member for urging the pin to extend into the opening. In another embodiment, the twistable actuator includes an asymmetrical contact member that is configured to be rotated in response to rotation of the twistable actuator. In this regard, the asymmetrical contact member may be configured to be rotated from a first position in which the engagement member extends into the opening defined by the card to a second position in which the asymmetrical contact member causes the card to be deflected such that the engagement member no longer extends into the opening defined by the card, thereby permitting the card to be slidably extended from the housing. The engagement member of either embodiment may have a tapered surface for facilitating the slidable insertion of the card at least partially within the housing.
In accordance with another embodiment, a pharmaceutical package is provided that includes a housing and a card having a plurality of blisters configured to store respective unit dose medications. The card is slidably disposed at least partially within the housing such that the plurality of blisters carried by the card are positioned within the housing. The card of this embodiment also defines an opening. The pharmaceutical package of this embodiment also includes an engagement member configured to extend into the opening defined by the card in the instance in which the card is disposed at least partially within the housing. The pharmaceutical package also includes a twistable actuator configured to disengage the card and the engagement member in response to rotation of the twistable actuator relative to the housing.
In one embodiment, the engagement member includes a pin. In this embodiment, the twistable actuator may be threadably connected to the pin such that rotation of the twistable actuator retracts the pin from the opening so as to permit the card to be slidably extended from the housing. The twistable actuator of this embodiment may also include a bias member for urging the pin to extend into the opening. In another embodiment, the twistable actuator includes an asymmetrical contact member that is configured to be rotated in response to rotation of the twistable actuator. In this regard, the asymmetrical contact member may be configured to be rotated from a first position in which the engagement member extends into the opening defined by the card to a second position in which the asymmetrical contact member causes the card to be deflected such that the engagement member no longer extends into the opening defined by the card, thereby permitting the card to be slidably extended from the housing. The engagement member of either embodiment may have a tapered surface for facilitating the slidable insertion of the card at least partially within the housing.
In a further embodiment, a method for accessing a medication within a pharmaceutical package is provided. The method includes providing the pharmaceutical package having a housing, a card carrying at least one medication that is disposed at least partially within the housing, and an engagement member that engages the card in an instance in which the card is disposed at least partially within the housing. In one embodiment, the card may include a plurality of blisters configured to store respective unit dose medications. The method also includes rotating a twistable actuator relative to the housing so as to disengage the card and the engagement member and slidably extending the card from the housing so as to permit access to the at least one medication carried by the card.
In one embodiment, the provision of the pharmaceutical package includes providing the card that defines an opening and the engagement member that extends into the opening defined by the card in the instance in which the card is disposed at least partially within the housing. In this embodiment, the engagement member may include a pin and the twistable actuator may be threadably connected to the pin such that rotating the twistable actuator comprises retracting the pin from the opening in the card so as to permit the card to be slidably extended from the housing. The method of this embodiment may also include urging the pin to extend into the opening, such as in an instance in which the twistable actuator has not been rotated. In another embodiment, the twistable actuator includes an asymmetrical contact member. In this embodiment, the rotating of the twistable actuator includes rotating the asymmetrical contact member from the first position in which the engagement member extends into the opening defined by the card to a second position in which the asymmetrical contact member causes the card to be deflected such that the engagement member no longer extends into the opening defined by the card, thereby permitting the card to be slidably extended from the housing. In one embodiment in which the engagement member has a tapered surface, the method also includes inserting the card at least partially within the housing at the tapered surface of the engagement member serving to guide the engagement member into the opening defined by the card.
By requiring a user to rotate a twistable actuator in order to release the card from the housing so as to access the medication carried by the card, a user having arthritis or otherwise having somewhat limited mobility in their fingers may more readily provide the required rotation and access the medication than pharmaceutical packages that rely upon the application of force, such as by a squeezing motion, applied to opposite edges or to other predefined portions of a housing. Thus a pharmaceutical package in accordance with embodiments of the present invention may be more user-friendly for users having arthritis or otherwise having somewhat limited mobility in their fingers, while still providing child resistance.
Having thus described embodiments of the invention in general terms, reference will now be made to the accompanying drawings, which are not necessarily drawn to scale, and wherein:
The present invention now will be described more fully hereinafter with reference to the accompanying drawings, in which some, but not all embodiments of the inventions are shown. Indeed, these inventions may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements. Like numbers refer to like elements throughout.
Referring to
As shown in more detail in the side view of
The pharmaceutical package 10 may include a variety of cards 16 that carry medication. In one embodiment, however, the card 16 is a blister card that includes a plurality of blisters 18 configured to store respective medications, such as pills, capsules or the like. For example, each blister 18 may store a unit dose of the medication to facilitate the administration of a proper dosage. Once the card 16 is extended from the housing 12, a user may access the medication within a blister 18 by pealing back the backing material that otherwise covers the blister and then extracting the medication from the blister.
The pharmaceutical package 10 also includes an engagement member configured to engage the card 16 in an instance in which the card is disposed at least partially within the housing 12. In the embodiment of
As shown in
In the embodiment illustrated in
Once the card 16 has been extended, the twistable actuator 26 may be released so as to return to its initial position, such as indicated by the alignment of the reference marks 32 on a surface of the housing 12. The twistable actuator 26 of one embodiment includes a bias member 30, such as a spring, disposed between the knob of the twistable actuator and the pin 22. For example, the rear portion of the pin 22 may define an internal opening within which a spring may be seated. Upon release of the twistable actuator 26 and the return of the twistable actuator to its initial position, the bias member 30 may exert a force upon the pin 22 so as to cause the pin to be at least partially de-threaded from the internally threaded portion 28 of the twistable actuator and to resume its rest position in which the pin extends further from the twistable actuator, as shown in
The pin 22 may include a tapered distal end 24 to facilitate the insertion of the card 16 at least partially within the housing 12. In this regard, the distal end of the pin 22 may have a tapered surface 24 that is oriented so as to face the open end 14 of the housing 12. As such, the insertion of the card 16 within the housing 12, such as following a user's access of a unit dose medication, will cause one end of the card to contact the tapered surface 24. As a result of the tapered surface 24, the card 16 will be deflected and will move somewhat beyond the pin 22. Once fully inserted, the opening defined by the card 16 will be aligned with the pin 22 such that the pin extends through the opening and again retains the card within the housing 12.
As described above, the pharmaceutical package 10 of this embodiment permits a user to extend the card 16 from the housing 12 and to access the medication by rotating the twistable actuator 26 and pulling the card at least partially from the housing. These motions may be more readily performed by users, including users having arthritis or otherwise having somewhat limited mobility in their fingers, in comparison to other pharmaceutical packages that may require force to be applied to predefined portions of the package, such as by means of a squeezing motion, in order to release the card. Thus, the pharmaceutical package 10 of this embodiment facilitates the controlled access to the medication by users having limited mobility while still providing child resistance.
The pharmaceutical package 10 may be embodied in various manners and, in one embodiment, may include other types of twistable actuators and engagement members. As shown in
Since the asymmetric contact member 46 is configured to rotate with the knob of the twistable actuator 44, rotation of the twistable actuator similarly causes rotation of the asymmetric contact member. By rotating the asymmetric contact member 46 such that the long dimension 48 is now oriented so as to be perpendicular to the card 16 and the short dimension 50 is oriented so as to be parallel to the card as shown in
As shown in
This process of securing the card 16 within the housing 12, controllably releasing the card in order to extend the card from the housing and access the medication and then reinserting and re-engaging the card within the housing can be repeated a number of times in order to access different medications carried by the card over the course of time. In each instance, the requirement that the twistable actuator 26, 44 be rotated and the card 16 be pulled from the housing 12 provides child resistance, while permitting a user having arthritis or otherwise having limited mobility in their fingers to more readily access the medication otherwise stored within the housing.
