The present invention relates to fluid containers, particularly vials and cartridges for holding medicant and dispensing medicant via an injector, and related methods.
Some fluid containers that are configured to hold medicant have a removable cap (e.g., a plastic cap) that fixes to a lip of the respective vial (or cartridge). A cap remover with a chamber sized to receive vials (or cartridges) having the same size (e.g., a first size) can remove caps from the lips of such vials.
Some wearable medicant injectors include an injector chamber for receiving vials (or cartridges) having the same size (e.g., the first size), for example after removing the respective caps. The wearable medicant injectors can dispense metered fluid from the vial (or cartridge) in its chamber to a patient. Differently sized vials can have portions that are too big and/or too small to fit in the respective chambers of the cap removers and the wearable medicant injectors.
The present application provides for a shell that is configured to cover at least a portion of a medicant container for insertion into another device. When the shell covers the medicant container so as to define an assembled container structure, the assembled container structure may be configured to nest in a chamber, of an injector or a decapper, that the medicant container is undersized for. For example, the chamber may be configured to receive another medicant container that has a larger outer periphery than that of the medicant container covered by the shell. The assembled medicant container structure may have outer dimensions that substantially match the outer dimensions of the second medicant container. The medicant container may include a stopper that is configured to receive a needle to receive medicant from within the medicant container. The medicant container may be a vial, or a cartridge (e.g., that includes a movable plunger).
Unless otherwise specified herein, the terms “substantially equal” or “substantially match” refer to values that are the same as one another or within +/−5%, 4%, 3%, 2%, or 1% of one another.
Unless otherwise specified herein, the terms “substantially equal” or “substantially match” when used in relation to the medicant container or the assembled container structure include the respective medicant container or assembled container structure being configured to nest with a corresponding structure or configured to nest with a structure that a referenced component nests with. For example, the medicant container may be configured to nest within the shell and/or the assembled container structure may be configured to nest within the chamber, which another differently sized medicant container is configured to nest with. The assembled medicant structure being configured to nest may include at least one outer dimension of the assembled container structure having at least one outer dimension that more closely conforms to at least one corresponding inner dimension, of the respective component that the assembled container structure nests within, than the medicant container. For example, configured to nest may include at least one outer dimension of the medicant container and/or the assembled container structure being within 5%, 4%, 3%, 2%, or 1% of the at least one corresponding inner dimension of the respective component the medicant container or the assembled container structure nests within.
According to an embodiment of the present disclosure, a system comprises a device including a chamber configured to receive a first medicant container having a first size configured to nest in the chamber. The system further comprises a second medicant container having a second size that is smaller than the first size, such that the second medicant container is not configured to nest in the chamber. The system further comprises a shell configured to cover at least a portion of the second medicant container so as to define an assembled container structure that is configured to nest in the chamber.
According to another embodiment of the present disclosure, a kit comprises a first medicant container having a first size, the first medicant container containing a medication. The kit further comprises a second medicant container having a second size that is less than the first size, the second medicant container containing the medication. The kit further comprises a shell configured to receive the second medicant container so as to define an assembled container structure, whereby the shell covers at least a portion of the second medicant container. The assembled container structure has outer dimensions that are substantially equal to outer dimensions of the first medicant container structure.
According to another embodiment of the present disclosure, an assembled container structure comprises a medicant container defining a base, a side wall extending up from the base to a neck, and a medicant container interface end extending up from the neck. The medicant container contains a medication. The assembled container structure further comprises a shell configured to receive the medicant container so as to define the assembled container structure that is sized in cross-section greater than the medicant container. The shell has an internal support surface that supports the base of the medicant container, and the support surface is spaced from the base of the shell so as to define a gap therebetween. The shell extends to the neck of the vial and terminates at the neck, such that the medicant container interface end of the medicant container extends out from the shell.

For the purposes of illustrating the system of the present application, there is shown in the drawings illustrative embodiments. It should be understood, however, that the application is not limited to the precise arrangements and instrumentalities shown. In the drawings:

For example, the chamber 36 may be configured to receive the first medicant container 34 having one of the above sizes such that the first medicant container 34 nests in the chamber 36 for injection by the injector 32. The chamber 36 may extend along a longitudinal axis A, that is perpendicular to both a lateral axis V and a transverse axis Z, each of which are perpendicular to one another.
For example, the injector 32 may include a housing 50 that defines a main cylindrical portion 52 that has an inner diameter DC (an example of a cross-sectional dimension) that is substantially equal to a corresponding portion of the first medicant container 34 such that the main cylindrical portion 52 abuts the first medicant container 34.
The injector 32 may include a mechanical interface 54 that is configured to receive a head 56 of the first medicant container 34. For example, the mechanical interface 54 may define cylindrical opening that is configured to hold the head 56. The mechanical interface 54 may be flexible (e.g., a flexible rubber gasket) such that the cylindrical opening is configured to widen to accommodate and secure the head 56.
The head 56 may include a lip 58, defined by a main body 60 of the first medicant container 34, and a head gasket 62. In some embodiments, the head includes a cover that is crimped over the head gasket and the lip to secure the head gasket to the lip while allowing insertion of a needle into the head gasket, as discussed below.
As discussed below in relation to decapping, in some embodiments, a cap attaches to the head to protect the head gasket prior to insertion into the injector. Such a cap can be removed to access the head gasket.
The injector 32 may include an inlet needle 70 (e.g., a cannulated inlet needle) fluidly connected to a pump 72 that is fluidly connected to the injection needle 38. A fluid line 74 may fluidly connect the inlet needle 70 to an inlet of the pump 72. The injection needle 38 may be fluidly connected directly to an outlet of the pump 72. In an embodiment, the injection needle is fluidly connected to an outlet of the pump.
The inlet needle 70 may be configured to be inserted into and through the head 56 into a chamber 73 of the first medicant container 34 to reach the medication held by the first medicant container 34 in the chamber 73. For example, the chamber 73 has a fixed volume for holding the medication.
During an injection, the pump 72 may suction medication from the inlet needle 70 via the fluid line 74, and output the medication to the injection needle 38 for injection into the patient. The pump 72 may be configured to inject a predetermined amount of medication, for example, based on a user's input. In an embodiment, the injector includes a third needle that is inserted into the head of the first medicant container and fluidly connected to atmosphere to equalize pressure within the first medicant container and atmosphere.
The main body 60 may define a neck 80, a base 82, a side wall 84, and a radially inwardly extending shoulder 86 that extends from the sidewall 84 to the neck 80. The neck 80 may extend between the head 56 and the radially inwardly extending shoulder 86 along the longitudinal axis A. For example, the sidewall 84 and the neck 80 may each define a respective cylindrical portion that extends along the longitudinal axis from respective ends of the radially inwardly extending shoulder 86.
The neck 80 may define a neck diameter DN (an example of a cross-sectional dimension). For example, the neck diameter DN may be any one of 13 millimeters (mm) or 20 mm. In some embodiments, the neck diameter DN is anyone of 10.5 mm, 16.5 mm, or 17.5 mm.
The head 56 may define a medicant container interface end that is configured to be received by the corresponding mechanical interface 54 of the injector 32. The head 56 (e.g., the medicant container interface) may define a head diameter DH (an example of a cross-sectional dimension) that is substantially equal to a diameter of the cylindrical opening of the mechanical interface 54. For example, the head diameter DH may be any one of 13 mm or 20 mm. In an embodiment, the diameter of the cylindrical opening is the same as the head diameter DH or within +/−5%, 4%, 3%, 2%, or 1% of the head diameter DH. In an embodiment, the head includes a cap (e.g., an aluminum cap) that defines a head diameter DH of anywhere from 13.3 mm to 13.5 mm or anywhere from 20.3 mm to 20.5 mm.
The side wall 84 may extend between the base 82 and the radially inwardly extending shoulder 86 along the longitudinal axis A. For example, the side wall 84 may define a cylindrical portion with a main body diameter DM that is substantially equal to the chamber diameter DC. The main body diameter DM may be any one of 16 mm, 22 mm, 24 mm, or 30 mm. The chamber diameter DC may be the same as the main body diameter DM or within +/−5%, 4%, 3%, 2%, or 1% of the main body diameter DM.
The entire first medicant container 34 may define a medicant container height HM that is substantially equal to a chamber height HC of the chamber 36. For example, the medicant container height HM may be any one of 35 mm, 40 mm, 45 mm, 55 mm, 60 mm, 65 mm, or 75 mm. The chamber height HC may be the same as the medicant container height or within +/−5%, 4%, 3%, 2%, or 1% of the medicant container height HM.

In some embodiments, the shell 104 and a second shell may be provided as part of a kit. For example, the second shell may be similar to the shell 104, but with at least one different inner dimension or at least one different outer dimension. Both the shell 104 and the second shell may have outer dimensions greater than those defined by size 2R of ISO 8362-1. Both the shell 104 and the second shell may have inner dimensions that are less than those defined by size 30R of ISO 8362-1.
The second medicant container 102 may be substantially the same as the first medicant container 34, except a height and/or cross-sectional dimension may be less than that of the first medicant container 34. The second medicant container 102 may be undersized such that the second medicant container 102 could be subject to inadvertent movement relative to the injector 32 that could cause the second medicant container 102 to become displaced relative to the injection needle 38. For example, the second medicant container 102 may be configured such that the second medicant container 102 is not configured to nest in the chamber 36.
Referring in particular to
The head 110 may define a medicant container interface end that is configured to be received by the corresponding mechanical interface 54 of the injector 32. In another embodiment, the medicant container interface end is undersized for the mechanical interface 54.

For example, the head diameter DH may be any one of 13 mm or 20 mm. In an embodiment, the diameter of the cylindrical opening is the same as the head diameter DH or within +/−5%, 4%, 3%, 2%, or 1% of the head diameter DH. In some embodiments, the head diameter is less than the diameter of the cylindrical opening such that the head is too small to nest in the mechanical interface 54. In an embodiment, the head includes a cap (e.g., an aluminum cap) that defines a head diameter DH of anywhere from 13.3 mm to 13.5 mm or anywhere from 20.3 mm to 20.5 mm.

The chamber diameter DC may be at least one of 10%, 20%, 30%, 40%, 50%, 100%, 150%, 200%, or 300% greater than the main body diameter DM.
The entire second medicant container 102 may define a medicant container height HM that is less than the chamber height HC of the chamber 36. For example, the medicant container height HM may be any one of 35 mm, 40 mm, 45 mm, 55 mm, 60 mm, 65 mm, or 75 mm. The chamber height HC may be the same as the medicant container height or within +/−5%, 4%, 3%, 2%, or 1% of the medicant container height HM. The chamber height HC may be at least one of 10%, 20%, 30%, 40%, 50%, 100%, 150%, 200%, or 300% greater than the medicant container height HM. In an embodiment, the second medicant container includes a head gasket, and the medicant container height extends from a top of the head gasket to the bottom of the base of the second medicant container. For example,
In an embodiment, the head of the second medicant container includes a head gasket and a cover that secures the head gasket to a lip of the second medicant container. For example, the head of the second medicant container may be substantially identical to the head of the first medicant container. In some embodiments, the head of the second medicant container may be smaller than the head of the first medicant container.
The shell 104 may be configured to cover at least a portion of the second medicant container 102 so as to define the assembled container structure 100. A cross-sectional dimension and height of the assembled container structure may be greater than those of the second medicant container 102. For example, the assembled container structure 100 may define a main structure body diameter DA that is greater than the main body diameter DM of the second medicant container 102. The main structure body diameter DA may be at least one of 10%, 20%, 30%, 40%, 50%, 100%, 150%, 200%, or 300% greater than the main body diameter DM of the second medicant container 102.
For example, the main structure body diameter DA may be any one of 16 mm, 22 mm, 24 mm, or 30 mm. The main structure body diameter DA may be the same as the chamber diameter DC and the main body diameter DM of the first medicant container 34, or within +/−5%, 4%, 3%, 2%, or 1% of the chamber diameter DC and the main body diameter DM of the first medicant container 34.

The neck diameter DN defined by the neck 114 may define the neck diameter of the assembled container structure 100. In some other embodiments, the shell defines the neck diameter of the assembled container structure (e.g., as discussed below with reference to
Referring now to
The at least one inner dimension of the shell 104 may define a portion of a receptacle 142 that is sized receive the medicant container 102, where the container has the at least one an outer dimension that corresponds to the second size defined by the standard. For example, the at least one inner dimension of the receptacle 142 of the shell 104 may be a body diameter, a neck diameter, a head diameter, and/or a length that corresponds with a respective body diameter, neck diameter, head diameter, and/or a length of the medicant container 102. Thus, the shell can be an adapter that is configured to adapt the second medicant container 102 having the second size to the chamber 36 of a device (e.g., the injector 32) having the first size.
For example, the shell 104 may include a pair of interlocking bodies 140 that when interlocked together define receptacle 142 that is configured to hold the second medicant container 102 relative to the shell 104. The interlocking bodies 140 may be interlocked together by moving the interlocking bodies 140 together along the illustrated dashed lines extending between the interlocking bodies 140. The assembled container structure 100 is defined by the second medicant container 102 and the shell 104 when the receptacle 142 holds the second medicant container 102. In some other embodiments, the shell locks onto the medicant container in another suitable manner. For example, as discussed below with reference to
The receptacle may define a diameter that is identical to the main body diameter DM of the second medicant container 102. In an embodiment, the diameter defined by the receptacle is within +/−5%, 4%, 3%, 2%, or 1% of the main body diameter DM of the second medicant container 102.
Each of the interlocking bodies 140 may be identical to one another. For example, each interlocking body 140 may define a portion 144 of an internal support surface (an example of a floor) that is configured to support the base 116 of the second medicant container 104. Each portion 144 of the internal support surface may be defined by a respective radially extending wall portion 148 of each interlocking body 140. In some other embodiments, the interlocking bodies are not identical to one another. For example, only one of the interlocking bodies may define the entire internal support surface.
The interlocking bodies may together define a sidewall 149 of the shell 104, which may define a sidewall of the assembled container structure 100. Each interlocking body 140 may define a window 151 in the sidewall 149 such that the user can see the second medicant container 102 through the window 151. For example, each window 151 is a radially extending through hole in the sidewall 149. In some embodiments, the sidewall includes at least a portion that is transparent or translucent such that the user can see the second medicant container through the transparent or translucent portion. In some embodiments, the sidewall has a translucent portion that is colored or tinted such that the user is unable to determine the color of the second medicant container or the medicant through the translucent portion.
In some embodiments, the shell does not include a window (e.g., as illustrated in
The shell 104 may include at least one fastener or coupler that fastens or locks the bodies 140 to one another. For example, as shown in
In some other embodiments, the interlocking bodies may be fastened or locked together in another suitable manner. For example, the shell may include a bolt or other fastener that is configured to couple adjacent bodies 140 to one another. Alternatively, the shell may include a toothed member on one of the bodies 140 that is configured to be received by an opening of the other one of the bodies 140.

The base may define a cavity 150 that extends longitudinally toward the inner support surface. In some embodiments, the base does not define the cavity.
Each interlocking body 140 may extend longitudinally to the neck 114 and terminate at the neck 114, such that the medicant container interface end of the second medicant container 104 extends out from the shell 104. For example, the interlocking bodies 140 may together define a radially inwardly extending rim 152 that is configured to abut the shoulder 120. The radially inwardly extending rim 152 may abut a portion of the neck 114.
The radially inwardly extending rim 152 may be longitudinally offset from the internal support surface of the shell 104 such that the second medicant container 102 is held therebetween. For example, each portion 144 of the internal support surface may abut the base 116 of the second medicant container 102 and the radially inwardly extending rim 152 may abut the shoulder 120 of the second medicant container 102.
Turning to
Injecting medicant from the assembled container structure 100 may be substantially the same as with the first medicant container 34. For example, during an injection, the pump 72 may suction medication from the inlet needle 70 in the second medicant container 102 via the fluid line 74, and output the medication to the injection needle 38 for injection into the patient. The pump 72 may be configured to inject a predetermined amount of medication, for example, based on the user's input. In an embodiment, the injector includes a third needle that is inserted into the head of the second medicant container and fluidly connected to atmosphere to equalize pressure within the first medicant container and atmosphere.

The structure neck diameter DAN may be at least one of 5%, 20%, 30%, 40%, 50%, 100%, 150%, 200%, or 300% greater than the neck diameter DN of the second medicant container 302.
For example, the structure neck diameter DAN may be any one of 13 mm or 20 mm. The structure neck diameter DAN may be the same as a corresponding portion of an interface in the chamber 36 and/or the neck diameter of the first medicant container 34, or within +/−5%, 4%, 3%, 2%, or 1% of the diameter of the corresponding portion of the interface and the neck diameter of the first medicant container 34.
The assembled container structure 300 may define a main structure body diameter DA that is greater than the main body diameter DM of the second medicant container 302. The main structure body diameter DA may be at least one of 10%, 20%, 30%, 40%, 50%, 100%, 150%, 200%, or 300% greater than the main body diameter DM of the second medicant container 302.
For example, the main structure body diameter DA may be any one of 16 mm, 22 mm, 24 mm, or 30 mm. The main structure body diameter DA may be the same as the chamber diameter DC and the main body diameter DM of the first medicant container 34, or within +/−5%, 4%, 3%, 2%, or 1% of the chamber diameter DC and the main body diameter DM of the first medicant container 34.
The structure height HA may be at least one of 10%, 20%, 30%, 40%, 50%, 100%, 150%, 200%, or 300% greater than the medicant container height HM of the second medicant container 102.
The structure height HA may be any one of 35 mm, 40 mm, 45 mm, 55 mm, 60 mm, 65 mm, or 75 mm. The structure height HA may be at least one of 10%, 20%, 30%, 40%, 50%, 100%, 150%, 200%, or 300% greater than the chamber height HC, such that the assembled container structure 300 extends outside of the chamber 36. The container structure 300 having such a height that it extends outside of the chamber 36 during use may provide for tamper resistance, as it may be more difficult for a user to inadvertently touch the plunger 250. In another embodiment, the structure height HA is substantially the same as the medicant container height HM of the first medicant container 34 or the chamber height HC.
The head may include the head gasket 324 and a crimp 256 that is configured to secure the head gasket 324 to the lip 324. For example, the crimp 256 may have a cylindrical sidewalls that are configured to deform radially inwardly to attach to the bottom side of the lip 324. The crim 324 may include a central hole at the top to provide access, for example, for the inlet needle 70 to pierce the head gasket 324 to reach the medication inside the variable volume chamber 252.
The shell 304 may not define an internal support surface longitudinally between the bottom of the shell 304 and the cartridge body 312. For example, the sidewall 349 may define an interior cylindrical hole that extends from the base of the bottom end of the shell to the radially inwardly extending rim 352. Providing a hole between the plunger 250 and atmosphere can prevent a vacuum from forming in a space defined by the plunger 250 and the shell 304, for example, when the plunger 250 moves longitudinally toward the head 310.
The hole may provide sufficient space for a user's finger to actuate the plunger 250. In an embodiment an actuator (e.g., an electromechanical actuator) is provided to press the bottom of the plunger to move the plunger and thereby dispense medication.
Injecting medicant from the assembled container structure 300 may be substantially the same as with the first medicant container 34. For example, during the injection, the pump 72 may suction medication from the inlet needle 70 in the second medicant container 302 via the fluid line 74, and output the medication to the injection needle 38 for injection into the patient. As the plunger 250 moves during dispensing of the medication to equalize pressure within the variable volume chamber 252 and atmosphere, pressure within the shell 304 below the plunger 250 may equalize with atmosphere through the bottom hole in the shell 304.

The assembled container structure 300′ includes a second medicant container 302′ and a shell 304′. The shell 304′ may include a wall 254′ and a structure head wall 260 that extends longitudinally from the wall 254′ and may define an outer dimension that is intermediate an outer dimension defined by the wall 254′ and an outermost dimension defined by the shell 304′.
The structure head wall 260 may be radially outward of a lip 322′ of the second medicant container 302′ and extend circumferentially around the lip 322′. For example, the structure head wall 260 may radially abut a head 310′ of the second medicant container 302′. The head 310′ may include a crimp 325′, and a cylindrical sidewall of the crimp 325′ may radially abut the structure head wall 260 such that the second medicant container 302′ is secured from radial movement relative to the shell 304′.
The top end of the assembly container structure 300′ may define a medicant container interface that is configured to be received by the corresponding mechanical interface 54 of the injector 32. For example, the head 310′ and the structure head wall 260 may together define the medicant container interface that is configured to be received by the mechanical interface of the injector 32.
For example, the structure head wall 260 may define a structure head diameter DAH that is substantially equal to a diameter of the cylindrical opening of the mechanical interface 54. For example, the structure head diameter DAH may be any one of 7.5 mm, 13 mm, or 20 mm. In an embodiment, the structure head diameter DAH is anywhere from 7.8 mm to 8.0 mm, anywhere from 13.3 mm to 13.5 mm, or anywhere from 20.3 mm to 20.5 mm. In an embodiment, the diameter of the cylindrical opening is the same as the structure head diameter DAH or within +/−5%, 4%, 3%, 2%, or 1% of the structure head diameter DAH.
The structure head diameter DAH may be the same as the head diameter DH of the first medicant container 34 or within +/−5%, 4%, 3%, 2%, or 1% of the head diameter DH of the first medicant container 34.
The head 310′ may define a medicant container interface end that is undersized for the mechanical interface 54. The structure head diameter DAH of the second medicant container 302′ may be at least one of 10%, 20%, 30%, 40%, 50%, 100%, 150%, 200%, or 300% greater than the head diameter DH of the second medicant container 302′.

The decapper 502 includes a decapping chamber 504 that may be configured to receive the assembled container structure 100 such that the decapper 502 is configured to remove a cap 506 from the assembled container structure 100. For example, the decapper 502 may be configured to remove the cap 506 from the head 110 of the second medicant container 102.
The decapping chamber 504 may define a decapper interface that is configured to receive a corresponding interface of the assembled container structure 100. For example, the assembled container structure 100 may include a radially inwardly extending shoulder 518 that defines an outwardly facing frusto-conically shaped surface and the decapper interface may define an inwardly facing frusto-conically shaped surface 520. When the outwardly facing frusto-conically shaped surface of the radially inwardly extending shoulder 518 abuts the inwardly facing frusto-conically shaped surface 520, the cap 506 may be disposed in a position such that the decapper 502 is configured to remove the cap 506.
The decapper 502 may include a housing 528, a movable member 530 that is movable relative to the housing 528, a handle 532 pivotable relative to the housing 528, and a linkage 534 pinned to the handle 532 and the movable member 530. The movable member 530 and linkage 534 are configured such that depression of the handle from an initial position in

The head 110 may define a decapper interface that is undersized such that, for example, the decapper 502 would not be configured to remove the cap 506 from the head 110 when only the second medicant container 102 is disposed in the decapping chamber 504. For example, when only the second medicant container 102 is disposed within the decapping chamber 504, the cap 506 may be disposed too low for the decapper 502 to remove the cap 506. The ramped surface 536 may thus be too high to remove the cap 506, when only the second medicant container 102 is disposed in the decapping chamber 504.
In some embodiments, any of the other assembled container structures are configured to nest in the chamber of the decapper such that the decapper is configured to remove a cap from the assembled container structure. The first medicant container 34 (shown in

The decapping system 500′ (an example of a system) may include a plurality of decapping chambers 504′ that are each configured to selectively receive the first medicant container 34 or the assembled container structure 100 to remove a corresponding cap 506′ from each of a plurality of first medicant containers 34 and assembled container structures 100. For example, the decapping chambers 504′ may be moveable in directed D1 relative to a platform 540. In some embodiments, the decapping chambers 504′ may be fixed relative to the platform, which may be a conveyor that is configured to move the decapping chambers 504′ in a first direction D1.
The decapping system 500′ may include opposing rail members 542 that each define a respective fixed member 530′ (e.g., as illustrated in
For example, the ramped surfaces 536′ may be formed by separate rail members 542 (e.g., one rail member 542 is disposed in front of the page when viewing
The head 110 may define a decapper interface that is undersized such that, for example, the decapper 502′ would not be configured to remove a cap 506 from the head 110 when only the second medicant container 102 is disposed in the decapping chamber 504. For example, when only the second medicant container 102 is disposed within one of the decapping chambers 504′, the corresponding cap 506 may be disposed too low for the decapper 502′ to remove the cap 506. The ramped surface 536′ may thus be too high to remove the cap 506, when only the second medicant container 102 is disposed in the decapping chamber 504′.
In some embodiments, any of the other assembled container structures are configured to nest in the chamber of the decapper such that the decapper is configured to remove a cap from the assembled container structure.
Each rail member 542 may include a protrusion 544 that is configured to abut the radially inwardly extending shoulders 86 and 518 of the first medicant containers 34 and the assembled container structures 100. For example, as the first medicant containers 34 and the assembled container structures 100 move in the first direction Di such that the ramped surfaces 536′ urge each cap 506 upwards, each protrusion 544 may abut the radially inwardly extending shoulders 86 and 518 of the corresponding first medicant containers 34 and assembled container structures 100. The protrusions 544 abutting the radially inwardly extending shoulders 86 and 518 of the corresponding first medicant containers 34 and assembled container structures 100 may prevent the corresponding first medicant containers 34 and assembled container structures 100 from moving upward with the corresponding caps 506 as the caps 506 are being removed.
The protrusions 544 may be configured to allow the first medicant containers 34 and assembled container structures 100 to move along the protrusions 544 in the first direction D1. For example, the protrusions 544 may be configured to not abut any part of the first medicant containers 34 and assembled container structures 100, unless the first medicant containers 34 and assembled container structures 100 are moved upward from the platform 540 (e.g., as the corresponding cap 506 is being removed).
