Patent Application
20110272297
The present invention generally relates to the field of packaging for pharmaceutical products such as pills, capsules, and the like and, more particularly, to packaging arrangements that facilitate the disposal of pharmaceutical product (e.g., to reduce the potential of illicit usage of unused pharmaceutical product).
Abuse, misuse, and overdose of pharmaceutical products (e.g., pain management drugs) are serious health concerns that affect many people on a daily basis all over the world. For instance, diversion and subsequent misuse or abuse may occur when a patient gets a prescription for a pharmaceutical product and does not use all of the pharmaceutical product for whatever reason (e.g., a doctor may prescribe a pharmaceutical product for a patient and advise the patient to take the pharmaceutical product on an “as needed” basis; a patient may be advised to use an entire prescribed amount of pharmaceutical product, but may unilaterally decide to discontinue use of the pharmaceutical product as one or more symptoms disappear). In any case, remaining pharmaceutical product may be ultimately acquired by an individual other than for whom the pharmaceutical product was originally prescribed (e.g., transferred by the original patient to another individual, such as family member or friend; stolen). While unused pharmaceutical product may be disposed of in the trash, this may not be viewed by some as a secure method of disposal.
In the case of transdermal analgesic patches, a used patch may still retain a significant amount of active ingredient in the patch. A used patch can be very dangerous and can even lead to death for people who have not been prescribed the patch. While some patch manufacturers recommend flushing used patches down the toilet, this practice has raised concerns about drug product entering the water supply. In some states, “take back” programs have been instituted, allowing users to request shipping materials in order to ship used or unused pharmaceutical product (e.g., patches, pills, capsules) to a certified disposal company. These programs are costly and require several actions by the patient at multiple times.
A first aspect of the present invention is embodied by a pharmaceutical product container (e.g., standard medication bottle, vessel, jar) that includes a cap (e.g., cover, lid), a container body, and a locking mechanism. The cap includes a cap body, and is movable relative to the container body between closed and open positions. The locking mechanism is disposable from an unlocked state to a locked state: 1) at least when the cap is in a closed position; 2) with the cap body remaining in a fixed position relative to the container body (i.e., the cap body need not be moved relative to the container body to activate the locking mechanism); and 3) by moving the locking mechanism relative to the cap body. The locking mechanism is unable to return from its locked state to its unlocked state at least when the cap is in its closed position. The cap may be repeatedly moved relative to the container body between its open and closed positions prior to the locking mechanism being disposed in its locked state.
A number of feature refinements and additional features are applicable to the first aspect of the present invention. These feature refinements and additional features may be used individually or in any combination. As such, each of the following features that will be discussed may be, but are not required to be, used with any other feature or combination of features of the first aspect of the present invention. If the cap is in the closed position and the lock is moved from its unlocked state to its locked state, the lock cannot be moved back to its unlocked state in the same general manner that it was moved into its locked stated. This may be viewed as “permanently” locking the pharmaceutical product container. Permanently locking the pharmaceutical product container at the completion of a medication regimen accommodates safer disposal of pharmaceutical product that remains within the pharmaceutical product container.
The locking mechanism may be part of the cap. In such a case, the “cap body” may be viewed as the remainder of the cap in relation to the locking mechanism. That is, the locking mechanism may be one part of the cap, and the cap body may be the remainder of the cap. In any case, the locking mechanism may be movable relative to the cap body to change from its unlocked state to its locked state. In one embodiment, a force that is external to the container (e.g., a manual force) is exerted on the locking mechanism to change the same from its unlocked state to its locked state.
The cap may be characterized as being detachably connectable to the container body (e.g., such that the cap may be repeatedly moved between its closed and open positions without damaging either the cap or the container body). When the cap is in its closed position, activation of the locking mechanism (by disposing the same in its locked state), may prevent the cap from being removed from the container body in its intended manner. That is, disposing the locking mechanism in the locked state (e.g., via a simple manual action) may attempt to permanently fix the cap to the container body such that a user may be unable to thereafter gain access to any pharmaceutical product within the enclosed space of the pharmaceutical product container. The locking mechanism may be actuated in any appropriate manner (e.g., mechanically, electronically) and may be associated with or located in any appropriate location (e.g., cap and/or container body). Numerous manners of permanently locking the cap to the container body to at least substantially limit access to pharmaceutical product within the container body exist.
In one arrangement, disposing the locking mechanism in the locked state provides a geometric interference between the cap and the container body that inhibits rotation of the cap relative to the container body in a direction and/or in an amount that would detach the cap from the container body (or otherwise allow the cap to be moved to its open position). In another variation of the geometric interference arrangement, the container body may include at least one locking segment (e.g., a single locking segment; a plurality of radially-spaced locking segments), and the cap may include a first locking tab (e.g., a rigid tab, a flexible or deflectable tab). The first locking tab may be disposable in an unlocking position where the first locking tab and the at least one locking segment are misaligned (an unlocked state for the locking mechanism), and a locking position where the first locking tab and the at least one locking segment are aligned (a locked state for the locking mechanism). The first locking tab may be closer to a central axis around which a sidewall of the container body is disposed when in the locking position versus the unlocking position. Here, having the first locking tab in the locking position inhibits rotation of the cap relative to the container body in a direction and/or in an amount that would detach the cap from the container body (or otherwise allow the cap to be moved to its open position). Stated otherwise, an end of the first locking tab may engage the locking segment when the first locking tab is disposed in the locking position and while attempting to rotate the cap relative to the container body in a direction that would detach the cap from the container body (or otherwise allow the cap to be moved to its open position). For instance, if a counterclockwise rotation of the cap relative to the container body would tend to detach the cap from the container body, the locking position of the locking tab may inhibit an amount of counterclockwise motion of the cap that would allow the same to be moved into its open position.
The geometric interference arrangement may also be designed such that the first locking tab is unable to return to the unlocking position from the locking position, at least if the cap is in its closed position when the locking mechanism is disposed in its locked state. For instance, the cap may further include a latch such that the first locking tab is disposed on a first side of the latch when the first locking tab is in the unlocking position, and such that the first locking tab is disposed on a second side of the latch when the first locking tab is in the locking position. In this regard, the first locking tab may be required to snap or otherwise deflect past the latch to move into the locking position. As a result, the first locking tab may be unable to return to the unlocking position from the locking position (e.g., the latch may block such a movement by the first locking tab). In one variation, the first locking tab may be aligned with an aperture of the cap such that the first locking tab may be directed through the aperture to move the first locking tab to the locking position.
In another arrangement, the locking mechanism in the locked state interacts with a seal disposed between the cap and the container body so as to incapacitate the seal or otherwise render the seal unusable in relation to allowing the cap to be moved to its open position. As a result, the cap may be limited from being pressed downwardly relative to the container body along a central axis of the container body an amount that would thereafter allow the cap to be rotated relative to the container body an amount such that the cap could be disposed in its open position (e.g., via being removed from the container body). Therefore, this incapacitation of the seal may be viewed as permanently locking the cap to the container body while in its closed position (e.g., by precluding the cap from being moved to its open position in the intended manner).
The locking mechanism may include an open space that is aligned with the above-noted seal. The open space may be accessible by the seal when the locking mechanism is in the unlocked state, and the open space may be inaccessible by the seal when the locking mechanism is in the locked state. For instance, the locking mechanism may be in the form of a movable plate, door, or slide, and the movable door may be movable between at least first and second door positions. In this regard, the door may be out of alignment with the open space in the first door position such that the open space is accessible by the seal, and may block access to the open space in the second door position such that the open space is inaccessible by the seal. Stated otherwise, the seal may be compressible by a first amount when the locking mechanism is in the unlocked state and by a second amount less than the first amount when the locking mechanism is in the locked state. A door lock may retain the door once moved into its second door position. Any appropriate door locking configuration may be utilized.
The above-noted movable door may be movable between the first and second door positions in a myriad of manners. In one variation, a sidewall of the container body is disposed about a central axis and the movable door moves along a movement axis that is generally perpendicular to the central axis. As another example, the movable door may rotate about a rotational axis that is generally collinear with the central axis. In either case, the movable door may include one of a notch and a projection, and the cap may include the other of the notch and the projection. In this situation, engagement of the notch with the projection may limit the movable door from moving from the second door position back to the first door position. In other words, this may aid in permanently locking the cap to the container body. Additionally, the movable door may include a first surface that is adapted to face away from an interior of the container body and a second surface that is adapted to face towards the interior of the container body, and the first surface may include a movement facilitation feature (e.g., tab, slot).
A second aspect of the present invention is embodied by a pharmaceutical product container (e.g., standard medication bottle, vessel, jar) that includes a cap (e.g., cover, lid), a container body, and a locking mechanism. The cap includes first and second sides or ends (e.g., oppositely disposed surfaces or structures). The first side includes a first connector configuration for interfacing with the container body to allow the cap to be moved (e.g., repeatedly) between open and closed positions. The second side of the cap incorporates a second connector configuration for interfacing with the container body. The locking mechanism is disposable from an unlocked state to a locked state. In this regard, when the second side of the cap interfaces with the container body, the locking mechanism is disposed in its locked state and is unable to return from its locked state to its unlocked state at this time.
A number of feature refinements and additional features are applicable to the second aspect of the present invention. These feature refinements and additional features may be used individually or in any combination. As such, each of the following features that will be discussed may be, but are not required to be, used with any other feature or combination of features of the second aspect of the present invention.
The first connector configuration associated with the first side or end of the cap may be a threaded connection, a “press and twist” arrangement, etc., while the second connector configuration associated with the second side or end of the cap may include the locking mechanism. Here, attaching the cap to the container body using the second connector configuration disposes the locking mechanism in its locked state. In this regard, the cap may be considered a “flip and lock” type cap. For protection and concealment, any appropriate cover (e.g., lid, hatch) may be disposed over the locking mechanism such that removal of the cover from a cap body of the cap exposes the second connector configuration (e.g., the second connector configuration may be concealed from view until use of the same is desired, at which time the cover may be removed to expose the second connector configuration). However, the locking mechanism could remain in an exposed state until the cap is “flipped” to interface the second connector configuration with the container body.
The second connector configuration and/or locking mechanism may include any appropriate component or combination of components that are selectively operable to permanently lock the cap to the container body. As an example, the second connector configuration may be in the form of at least one flexible latch (e.g., a cantilever) that is operable to grip onto or otherwise attach or connect to a corresponding structure on the container body. In one variation, a plurality of flexible latches are located around a perimeter of the cap. Each flexible latch may include a camming section and a locking section (e.g., a free end of the flexible latch). For instance and when a sidewall of the container body is disposed about a central axis, each flexible latch may move at least generally away from the central axis when positioning the cap on the container body by a movement of the cap relative to the container body at least generally along the central axis (e.g., via the camming section engaging with a portion of the container body), and then may move at least generally toward the central axis to dispose the locking mechanism in the locked state (e.g., via the locking section engaging with a portion of the container body). As another example, the container body may include at least one catch such that a first segment of relative motion between the cap and the container body along the central axis causes the catch to engage an aligned flexible latch (e.g., the camming section of the flexible latch) and move the aligned flexible latch at least generally away from the central axis. Continued relative motion between the cap and the container body along the central axis may result in the flexible latch moving at least generally toward the central axis after clearing an aligned catch to dispose the locking mechanism in the locked state (e.g., via the locking section of the flexible latch engaging with the catch).
A first motion type may be used to interconnect the cap and container body using the first connector configuration on the first side or end of the cap (e.g., rotational). A second motion type may be used to interconnect the cap and container body using the second connector configuration on the second side or end of the cap (e.g., axial, for instance collinear or parallel with a long axis of the container body). In one embodiment, the first and second motion types are different from each other.
A third aspect of the present invention is embodied by a pharmaceutical product container (e.g., standard medication bottle, vessel, jar) that includes a cap (e.g., cover, lid), a container body, and a locking mechanism disposable from an unlocked state to a locked state. The cap is repeatedly movable relative to the container body between closed and open positions when the locking mechanism is in an unlocked state. The container body includes at least one locking segment (e.g., a single locking segment; a plurality of radially-spaced locking segments), and the cap includes a first locking tab (e.g., a rigid tab, a flexible or deflectable tab). The first locking tab may be disposable in an unlocking position where the first locking tab and the at least one locking segment are misaligned (an unlocked state for the noted locking mechanism), and a locking position where the first locking tab and the at least one locking segment are aligned (a locked state for the noted locking mechanism). The features pertaining to the locking segment and first locking tab, discussed above in relation to the first aspect, may be utilized by the above-noted combination that defines the third aspect. The locking mechanism, utilized by the above-noted combination that defines the third aspect, may be configured such that it is unable to return to its unlocked state after being disposed in its locked state (at least if the cap is in its closed position when the locking mechanism changes from its unlocked state to its locked state).
A fourth aspect of the present invention is embodied by a pharmaceutical product container (e.g., standard medication bottle, vessel, jar) that includes a cap (e.g., cover, lid), a container body, and a locking mechanism disposable from an unlocked state to a locked state. The cap is repeatedly movable relative to the container body between closed and open positions when the locking mechanism is in an unlocked state. The pharmaceutical product container further includes a seal between the cap and container body, and the locking mechanism interacts with this seal, at least when the locking mechanism is in its locked state, in a manner that the cap cannot thereafter be moved to an open position. The features pertaining to this seal and the locking mechanism, discussed above in relation to the first aspect, may be utilized by the above-noted combination that defines the fourth aspect. The locking mechanism, utilized by the above-noted combination that defines the fourth aspect, may be configured such that it is unable to return to its unlocked state after being disposed in its locked state (at least if the cap is in its closed position when the locking mechanism changes from its unlocked state to its locked state).
Any feature of any other various aspects of the present invention that is intended to be limited to a “singular” context or the like will be clearly set forth herein by terms such as “only,” “single,” “limited to,” or the like. Merely introducing a feature in accordance with commonly accepted antecedent basis practice does not limit the corresponding feature to the singular (e.g., indicating that a locking mechanism includes “a latch” alone does not mean that the locking mechanism includes only a single latch). Moreover, any failure to use phrases such as “at least one” also does not limit the corresponding feature to the singular (e.g., indicating that a locking mechanism includes “a latch” alone does not mean that the locking mechanism includes only a single latch). Use of the phrase “at least generally” or the like in relation to a particular feature encompasses the corresponding characteristic and insubstantial variations thereof (e.g., indicating that a container body is at least generally cylindrical encompasses the container body being cylindrical). Finally, a reference of a feature in conjunction with the phrase “in one embodiment” does not limit the use of the feature to a single embodiment.
Pharmaceutical product may be enclosed within the container body by having the cap it its closed position. A “pharmaceutical product” as used herein may generally define any material or substance used in the course of a medical treatment, medical diagnosis, therapy, or the provision of any other appropriate medical care. A given material need not contain an active drug compound or ingredient to be considered a “pharmaceutical product” for purposes of the present invention.
A pharmaceutical product within the container may be in any appropriate form, in any appropriate dose, and of any appropriate type. A pharmaceutical product encompasses both a single-dose configuration (e.g., a single pill) and a multiple dose configuration (e.g., a plurality of pills). Pharmaceutical product may be in any appropriate form such as (but not limited to) pills, tablets, chewables, capsules, powders, fluids (e.g., liquids, suspensions, emulsions), patches (e.g., transdermal patches), films (e.g., transmucosal or buccal), strips (e.g., transmucosal or buccal), or the like. Further, a “pharmaceutical product” may refer to or include any “drug” as defined in Title 21 of the United States Code, Section 321(g)(1).
All pharmaceutical product within the container may be of at least substantially common dose. Alternatively, some pharmaceutical product could be of one dose (e.g., a prescribed dose), while some pharmaceutical product could be of a different dose (e.g., in the form of a transdermal patch that has been used by a patient, such that at least part of its original dosage has already been transdermally administered to a patient). All pharmaceutical product within the container could be in a common first condition. For instance and in the case of transdermal patches, all transdermal patches within the container could be contained within individual primary packaging (e.g., within a sealed pouch, jacket, foil wrapping, or the like), or all transdermal patches within the container could be in an exposed state (e.g., where the individual transdermal patches have been removed from their associated primary packaging before being disposed within the container). Some pharmaceutical product within the container could be in a common first condition, such as contained within individual primary packaging (e.g., within a sealed pouch, jacket, foil wrapping, or the like), while some pharmaceutical product within the container could be in a common second condition (e.g., in an exposed state or where the individual transdermal patches have been removed from their associated primary packaging before being disposed within the container).
Each transdermal patch that may be used in conjunction with the present invention may include any appropriate pharmaceutical product. Examples of appropriate pharmaceutical products that may be included in such transdermal patches include (but are not limited to): U.S. Drug Enforcement Administration (DEA) scheduled (e.g., Schedule II) drugs such as fentanyl, lidocaine, tetracaine, prilocaine, thebaine, buprenorphine, sufentanil, alfentanil, codeine, dihydrocodeine, hydrocodone, hydromorphone, levorphanol, methadone, morphine, nalbuphine, noscapine, opium, oxycodone, and propoxyphene; non-steroidal anti-inflammatory drugs (NSAIDs) such as ketoprofen, diclofenac, flurbiprofen, and ibuprofen; steroids such as testosterone and estradiol; psychoactive drugs such as buspirone; vitamins such as vitamin B12; vasodilators such as nitroglycerin; vaccines; antiemetics; capsaicin; and nicotine. Further, any transdermal patches utilized with the present invention can function to provide drug delivery in any appropriate manner. For instance, such transdermal patches may include those functioning via a passive delivery mechanism (e.g., pharmaceutical product located within the adhesive of the patch, within a reservoir of the patch, within a semisolid matrix (e.g., a gel)) or via an active delivery mechanism (e.g., iontophoresis, sonophoresis, electroporation, microneedles, abrasion, needle-less injection, suction, stretching, magnetophoresis, radio frequency, lasers, photomechanical waves, temperature (e.g., heat-activation)).

Various embodiments of pharmaceutical product containers will be described in relation to the accompanying figures. A pharmaceutical product container with pharmaceutical product therein may be referred to as a “pharmaceutical product supply.” In any case, these pharmaceutical product containers are configured to store “pharmaceutical product” as described herein (e.g., in any appropriate form, in any appropriate dose, and of any appropriate type), and furthermore include one or more features to selectively “permanently lock” a pharmaceutical product container so as to limit a cap of the pharmaceutical product container from being removed from a container body of the pharmaceutical product container. As used throughout, the terms “permanent,” “limit,” “inhibit” or the like and variations thereof are used in the sense of at least substantially limiting or inhibiting access to an interior of the container body (and any pharmaceutical product inside the container body) in the manner traditionally used to gain access to the interior of such containers (e.g., pressing down on the cap and rotating the cap relative to the container body, depressing a tab and rotating the cap relative to the container body, flipping the cap upward relative to the container body). In this regard, the “permanent” locking arrangements and mechanisms discussed herein may not necessarily limit or inhibit access to the interior of the container body in the case of non-traditional access methods being used (e.g., via damaging one or more of the cap and container body). Additionally, “selectively” as used herein means that a user (e.g., patient) may voluntarily decide when to manually, permanently lock the container.
Each of the container body 14 and the cap 20 may be of any appropriate size, shape, configuration, and/or type, and furthermore may be formed from any appropriate material or combination of materials. Generally, the container body 14 includes an open end 16 through which pharmaceutical product 26 may be directed into and removed from an internal space 18 of the container body 14 when the cap 20 is in an open position (e.g. where the open end 16 of the container body 14 is exposed). When the cap 20 is in a closed position (as shown in
The container 100 generally may include a container body 104 and a cap 108, and pharmaceutical product 112 may be stored or received within the container body 104. At least in this regard, the container 100 may be similar to the pharmaceutical product container 12 of
The container 100 may also include a permanent locking mechanism 116 that can be selectively actuated or disposed by a user (e.g., patient) from an unlocked state to a locked state such that the locking mechanism 116 is unable to or is at least limited from being able to return to the unlocked state from the locked state; doing so permanently locks the container 100 (i.e., permanently affixes the cap 108 to the container body 104) to limit access to an interior of the container body 104 and any pharmaceutical product 112 thereinside. Stated otherwise, the permanent locking mechanism 116 may “override” the above-described common features that allow the cap 108 to be “detachably attached” to the container body 104 such that the common features are at least substantially inhibited from allowing the cap 108 to be moved into an open position in relation to the container body 104. As shown, the locking mechanism 116 may be contained within or at least associated with the cap 108 instead of the container body 104 to allow the same to be used with standard medication bottles while filling prescriptions, although the locking mechanism 116 could also be contained within or at least associated with the container body 104. The locking mechanism 116 may include one or more of a geometric interference locking arrangement 120 and a seal incapacitation locking arrangement 124. Each of these arrangements will be discussed in more detail below.
The geometric interference locking arrangement 120 may be any feature or combination of features operable to limit rotation of the cap 108 in relation to the container body 104 in a manner that would allow the cap 108 to be moved to an open position (e.g., in a direction and amount that would detach the cap 108 from the container body 104) to thus permanently affix the cap 108 to the container body 104. Some amount of relative movement between the cap 108 and container body 104 may be allowed—just not enough to allow the cap 108 to move to an open position. For instance, the geometric interference locking arrangement 120 may include one or more protrusions, latches, apertures, etc. that are operable to interact with one or more protrusions, latches, apertures, etc. on the container body 104. The seal incapacitation locking arrangement 124 may be used with caps 108 that include a compressible seal 109 that allows the cap 108 to be pressed downwardly before being rotated to be removed from the container body 104. In this regard, the seal incapacitation locking arrangement 124 may render the seal 109 at least substantially incompressible, or at least affects the compressibility of the seal 109 in a manner that precludes the cap 108 from being compressed relative to the container body 104 to a degree that would allow the cap 108 to be removed from the container body 104. That is, the cap 108 may be limited from being moved or pressed downwardly towards the container body 104, and may thus be permanently locked to the container body 104. It should be appreciated that the locking mechanism 116 may incorporate mechanical and/or electrical features (e.g., activation buttons, pre-set or programmable timers, wireless signals). In one embodiment, the locking mechanism 116 is manually activated, for instance by a user exerting a manual force to move the locking mechanism 116 from a position associated with an unlocked state, to a position associated with a locked state. While the various geometric interference locking arrangements and seal incapacitation locking arrangements will be described herein as being components of a cap, it should also be appreciated that the geometric interference locking arrangement and seal incapacitation locking arrangement could be considered a combination of components of the caps interacting with components of the container bodies.
In any event,
For instance, the cap 208 may be detachably connectable with the container body 204 when the first side 228 interfaces with the container body 204 (e.g., if the cap 208 was interfaced with the container body 204 in the orientation shown in
The cap 208 may include a cap body 248 and a removable cover 252 (shown in
Thereafter, continued movement of the cap 208 along the central axis 206 causes the flexible latch 256 to move at least generally away from the central axis 206 owing to the interaction of the camming section 264 with the catch 260. Stated otherwise, a first segment of relative motion between the cap 208 and the container body 204 causes the catch 260 to engage an aligned flexible latch 256 and move the flexible latch 256 at least generally away from the central axis 206. In any event, continued movement of the cap 208 along the central axis 206 results in the locking section 268 eventually clearing the aligned catch 260, which disposes the geometric interference locking arrangement 220 in the locked (i.e., permanently locked) state. That is, any attempt to pull the cap 208 away from the container body 204 (e.g., along the central axis 206) would result in the locking section 268 contacting the catch 260, thus inhibiting movement of the cap 208 to its open position.
Although not shown, the catch 260 may include an aperture or bore that is sized to snugly receive the locking section 268. Such an aperture or bore may serve to further reduce both movement of the cap 208 along the central axis 206 and rotational movement of the cap 208 about the central axis 206 in a manner that would allow the cap 208 to be moved into its open position. It should be appreciated that as the cap 208 was already pressed or moved downwardly along the central axis 206 for the locking section to clear the catch 260, the cap 208 may be at least generally inhibited from further movement downward along the central axis 206. This feature reduces the likelihood of disengagement of the flexible latch 256 from the catch 260 and thus removal of the cap 208 from the container body 204. In one arrangement, a plurality of flexible latches 256 may be disposed about a perimeter of the cavity 245 of the second side 232 of the cap 208, one or more of which may engage with one or more catches 260 disposed about a periphery of the container body 204. For instance, the plurality of flexible latches 256 may be appropriately formed or disposed on a ring (not shown), and the ring may be, for instance, press-fit into the cavity 245 on the cap 208.
a-5b and 6a-6b illustrate partial perspective and sectional views of a pharmaceutical product container 300 incorporating a geometric interference locking arrangement 320 according to another embodiment. Similar reference numerals will be used when possible which may imply that the referenced component includes some or all of the features of the earlier used reference numeral. With initial reference to
The geometric interference locking arrangement 320 may include at least one first locking tab 356 (e.g., a deflectable tab) on the cap body 348 that is disposable in at least unlocking and locking positions. For instance, the unlocking position may be when the first locking tab 356 and at least one of the locking segments 360 are misaligned (see
Of course, the first locking tab 356 could be oriented or disposed on the cap body 348 so as to protrude in an opposite direction in the case where rotating the cap 308 in a clockwise direction relative to the container body 304 would tend to detach the cap 308 from the container body 304. In some arrangements, a second or additional locking tabs 356 could be provided at various radial positions in the cap body 348, all of which may protrude in the same direction or some of which may protrude in one direction and some of which may protrude in other directions. In some arrangements, the locking tabs 356 may be arranged or designed so as to protrude upwardly so that when pressed inwardly so as to at least generally align with a corresponding locking segment 360 on the container body 304, an attempt to move the cap 308 away from the container body 304 along the central axis 306 would result in the locking tabs 356 engaging the corresponding locking segment 360 and thus disallowing removal of the cap 308.
To move the first locking tab 356 from the unlocking position to the locking position, the first locking tab 356 may be pressed inwardly towards the central axis 306 of the container body 304 in any appropriate manner (e.g., using a fingernail or a key) such that the first locking tab 356 is closer to the central axis 306 in the locking position than in the unlocking position. For example, the first locking tab 356 may be disposed within or aligned with an aperture 357 in the cap body 348 such that the first locking tab 356 may be directed through the aperture 357 to move the first locking tab 356 to the locking position.
Additionally, the geometric interference locking arrangement 320 may be designed such that the first locking tab 356 is unable to return to the unlocking position from the locking position. For instance, the cap body 348 may include a latch 358 (e.g., tab, catch, protrusion), which may be disposed in or aligned with the aperture 357 and which may be operable to limit or block the first locking tab 356 from returning to the unlocking position from the locking position (shown in
a-7b and 8a-8b illustrate partial perspective and sectional views of a pharmaceutical product container 400 incorporating a seal incapacitation locking arrangement 424 according to another embodiment. Similar reference numerals will be used when possible which may imply that the referenced component includes some or all of the features of the earlier used reference numeral. With initial reference to
As the name suggests, the seal incapacitation locking arrangement 424 is adapted to interact with and incapacitate the seal 409 to permanently lock the container 400 (i.e., limit the cap 408 from being removed from the container body 404). With particular reference to
When the seal incapacitation locking arrangement 424 is in a locked state, the seal 409 may be unable to access the open space 472, and thus the seal 409 may not be able to be compressed to a degree that allows the cap 408 to be removed from container body 404. In this regard, the container 400 may be permanently locked because the cap 408 may not be able to be moved downwardly along the central axis 406. In one arrangement, the seal incapacitation locking arrangement 424 may include a moveable door, slide, or plate 476 disposed within or associated with the cap 408 that may be operable to enter the open space 472. That is, the movable door 476 may be able to transition between at least a first door position where the movable door 476 is out of alignment with the open space 472 and the seal 409 is compressible by the cap body 448 by a first amount (as in
The movable door 476 need not be a single piece of generally constant thickness as shown in
Further, and even though the movable door 476 may already be wedged between the cap body 448 and the seal 409 and thus be resistant to movement back to the first door position (e.g., as shown in
Any appropriate movement facilitation feature may be disposed and/or formed on the movable door 476 to aid a user in moving the door into the second door position. For instance, the movable door may include a tab 488 protruding therefrom which may be gripped or pressed by a user to slide or otherwise move the movable door 476. The tab 488 may be disposed on a first surface that faces away from an interior of the container body 404 which may face away from a second surface that faces towards the interior of the container body 404.
Additionally, while the movable door 476 is shown as being movable along a movement axis 492 that is generally perpendicular to the central axis 406, other arrangements are also envisioned. For example and with reference now to
In this embodiment, the movable door 476′ may be rotated (e.g., via a coin or the like being inserted into the slot 488′) either clockwise or counterclockwise from a first door position to a second door position. In the first door position (
It should be appreciated that any features of any of the embodiments and arrangements may be used in conjunction with any of the other embodiments. As merely one example, a container having a container body and a cap may include both a geometric interference locking arrangement 220 of
