     TECHNICAL FIELD 
     The invention relates generally to an actuator assembly for a dispenser and more particularly, to an dispenser actuator assembly having a base member configured to mount on a crushable glass ampoule assembly wherein an actuator assembly in the form of a first actuator arm and a second actuator arm are operably connected to the base member and dimensioned to crush the glass ampoule assembly. 
     BACKGROUND OF THE INVENTION 
     Dispensers such as glass ampoule assemblies are well known in the art and are often designed to be single-use disposable dispensers. A glass ampoule assembly typically includes a rupturable container such as a glass ampoule that contains a flowable material to be dispensed. The glass ampoule is contained in an outer container that may be made from a plastic material and having an open end and a closed end. The glass ampoule assembly may further include an applicator such as a swab that fits in the open end of the outer container. The applicator assists in dispensing the flowable material after the glass ampoule is ruptured, or crushed. The glass ampoule assembly may also include a cover member such as a cardboard sleeve that is used when initially storing and transporting the glass ampoule assembly wherein the applicator end of the glass ampoule assembly is inserted into the cardboard sleeve. An opposite end of the glass ampoule assembly may be inserted into the cardboard sleeve wherein the applicator extends out of the sleeve. A user may squeeze the cardboard sleeve via finger pressure to deflect the plastic outer container and crush the glass ampoule wherein the flowable material is dispensed from the applicator. Other glass ampoule assemblies may utilize a cap member that fits over the applicator rather than a cardboard sleeve. 
     Attempts have been made to design ampoule holders that assist in rupturing the ampoule. These designs, however, have been high in cost and cumbersome in design and operation. Furthermore, the glass ampoule is not crushed in an optimum location wherein dispensing of the flowable material becomes problematic because of obstruction from fractured pieces of the glass ampoule. 
     Additional problems have also been experienced with the glass ampoule assemblies. In some instances, users do not have sufficient finger strength to crush the glass ampoule. For example, users of advanced age oftentimes have arthritis and cannot crush the glass ampoule. In other instances, upon rupturing the glass ampoule, glass shards puncture through the outer container and injure the user. In still other instances, the glass ampoule is typically crushed at a central location of the glass ampoule. Rupturing the ampoule at the central location leaves a dome-shaped end portion of the glass ampoule intact. The dome-shaped end portion may end up positioned at the applicator wherein the flow of the flowable material is restricted from the dispenser. Furthermore, some actuator structures are integral with the overall dispenser assembly and do not provide an ability to be reused. 
     While glass ampoule assemblies and associated dispenser/ampoule holders/actuator assemblies according to the prior art provide a number of advantageous features, they nevertheless have certain limitations. The present invention seeks to overcome certain of these limitations and other drawbacks of the prior art, and to provide new features and new uses not heretofore available. A full discussion of the features and advantages of the present invention is deferred to the following detailed description, which proceeds with reference to the accompanying drawings.

In an exemplary embodiment, the first container  12  is made from a rigid frangible or crushable material such as glass. The first container  12  may be a traditional glass ampoule. Glass ampoules are known in the art and provide a hermetically-sealed chamber for containing the flowable material M. In one exemplary embodiment, a single glass ampoule  12  is used. It is understood that the dispenser  10  could be configured to use multiple glass ampoules  12  as described in greater detail below. 
       FIGS.  1 - 4    further show the second container  14 , or outer container  14 , which can be in the form of an applicator body. The second container  14  has an open first end  36  and a closed second end  38 , and an outer wall  40  therebetween. The outer wall  40  of the second container  14  defines a second chamber  42 . The second chamber  42  is cooperatively dimensioned and configured to receive at least a portion of the first container  12 , and typically the entire first container  12  is received in the second container  14 . Thus, in an exemplary embodiment, the second container  14  is generally cylindrical and receives the first container  12  in a generally snug-fit configuration. The second container  14  is made from a flexible resilient material such as plastic in an exemplary embodiment. The second container  14  may be transparent or translucent plastic wherein the flowable material M in the first container  12  can be visible through the second container  14  and also through the first container  12 . The second container  14  may also be made from opaque material when the flowable material M or other contents are light sensitive. 
       FIGS.  1 - 4    also show the applicator  16  or applicator assembly  16 . The applicator assembly  16  assists in dispensing the flowable material M from the dispenser  10  to a receiving surface. Any applicator assembly  16  that performs this function can be used in the dispenser  10 . Thus, the applicator assembly  16  can take various forms including a swab assembly, a dropper assembly, a roller ball or a brush assembly. The applicator assembly  16  can further be a sponge, foam applicator, fabric, gauze, pen-type applicator or flocked tip. The swab applicator may also take various forms such as being made from absorbent, porous material, and that relies on a wicking action to dispense the flowable material M. It is also understood that the applicator assembly  16  may have a filter member  44  operably associated therewith. The filter member  44  is structured to allow passage of the flowable material M through the filter member  44  while preventing passage of glass shards from the fractionated glass ampoule  12 . The filter member  44  may be positioned between the first end  22  of the first container  12  and the applicator assembly  16 . Further, the filter member  44  may be positioned between the glass ampoule  12  and a tip of the applicator assembly  16 . 
     In the exemplary embodiment of the applicator assembly  16  of  FIGS.  1 - 4   , the applicator assembly  16  has a hub  46  or base member  46  having a first end  48  and a second end  50 . It is understood that the base member  46  has an internal conduit that is in fluid communication with the second container  14  for the flowable material M to pass through the conduit and onto a receiving surface. The first end  48  is dimensioned to fit into the open first end of the second container  36 . The second end has a post  52  that receives a tip  54 . The tip  54  can be made from the various materials as described above wherein the flowable material M can be dispensed from the tip  54  and onto a receiving surface. In one exemplary embodiment, the tip  54  could be a flocked tip for enhanced dispensing of the flowable material M. 
     In another exemplary embodiment, the applicator assembly  16  could be in the form of a swab assembly. The swab assembly can be made from material that promotes dispensing of the flowable material M through the swab assembly and onto a receiving surface. The applicator assembly  16  can also include other types of tips capable of applying flowable material onto a receiving surface. 
     In another exemplary embodiment, the applicator assembly  16  can be in the form of a dropper assembly. The applicator assembly  16  has a base having a protrusion extending therefrom at one end. The base has a dropper tip member extending from an opposite end. The applicator assembly  16  has a central conduit extending therethrough from a distal end of the protrusion to a distal end of the dropper tip member. The protrusion has a generally annular configuration and is dimensioned to be received by the open first end  36  of the second container  14 . In an exemplary embodiment, the protrusion and the open first end  36  of the second container  14  are cooperatively dimensioned wherein the protrusion is received in the open first end  36  in an interference fit. As further described below, the applicator assembly  16  is configured to receive the flowable material M from the fractionated or crushed first container  12  and to dispense the flowable material M onto a receiving surface. 
     To fabricate the dispenser  10 , the first chamber  20  of the first container  12  is filled with a desired flowable material M. The open end of the first container  12  through which the flowable material passed to fill the first container  12  is sealed as is known in glass ampoule technology. A sealed glass ampoule  12  having the flowable material M therein is thereby provided. The filled first container  12  is then inserted through the open first end  36  and into the second chamber  42  of the second container  14 . Preferably, the first container  12  is positioned in its entirety within the second chamber  42  of the second container  14 . The filter member  44 , if utilized, is inserted into the open first end  36  of the second container  14  and adjacent the first end of the first container  12 . Once the first container  12  is positioned in the second container  14  as well as the filter member  44 , the applicator assembly  16  is connected to the second container  14 . Thus, the filter member  44  is positioned between the glass ampoule  12  and the applicator assembly  16 . As can be appreciated from  FIGS.  1 - 4   , the first end  48  of the applicator assembly  16  is inserted into the open first end  36  of the second container  14 . This connection may be in an interference fit, snap-fit or connected with adhesives as well. The tip  54  is secured to the post  52 . 
     The cover member  18  is designed to initially cover the applicator assembly  16  prior to activating the dispenser  10 . The cover member  18  is dimensioned to fit snugly over the applicator assembly  16 , cover the tip  54  and extend over a portion of the dispenser  10 . A distal end of the cover member  18  is a closed end. When preparing to activate the dispenser  10 , the cover member  18  is removed from the dispenser  10 . With the present invention as described in further detail below, the cover member  18  is not used during activation of the dispenser  10 . It is also understood that the dispenser  10  can incorporate an identifying label. 
     It is understood that the dispenser  10  utilizes the cover member  18  in a single-use type container as described above and shown in  FIGS.  1 - 4   . The dispenser  10  may also eliminate the cover member  18  and be packaged in other outer packaging such as blister packaging. 
       FIGS.  5 - 8    disclose another exemplary embodiment of a glass ampoule assembly. The assembly has generally similar structures as the glass ampoule assembly  10  of  FIGS.  1 - 4    and like structures will be designated with identical reference numerals. As shown in  FIGS.  5 - 8   , the glass ampoule assembly  10  generally includes a first container  12 , a second container  14 , or outer container  14 , and an applicator assembly  16 . The elements are structured and connected as with the glass ampoule assembly of  FIGS.  1 - 4   . An alternative form of the cap member  18  is utilized in the embodiment of  FIGS.  5 - 8   . 
     If desired, the dispenser  10  may also utilize the cover member  18  in the form of a cardboard sleeve, as is known the art. The cover member is designed to initially cover the applicator assembly  16  prior to activating the dispenser  10 . The cover member  18  is dimensioned to fit snugly over the applicator assembly  16  and extend over a portion of the dispenser  10 . One end of the cover member  18  may be closed although it is understood that both ends of the cover member  18  could be open ends. When preparing to activate the dispenser  10 , the cover member  18  is removed from the dispenser  10 . In certain prior art applications, an end of the dispenser  10  opposite of the applicator assembly  16  is inserted into the cover member  18 . With the present invention as described in further detail below, the cover member  18  is not used during activation of the dispenser  10 . As discussed, the cover member  18  is a cardboard or paper-based material in an exemplary embodiment. It is also understood that the dispenser  10  can incorporate an identifying label. 
     As shown in  FIGS.  9 - 18   , the present invention utilizes a dispenser actuator assembly generally designated with the reference numeral  100 . The dispenser actuator assembly  100  may also be referred to as an ampoule actuator assembly  100  or dispenser/ampoule holder  100 . As explained in greater detail below, the dispenser actuator assembly  100  cooperates with the dispenser  10  to actuate the dispenser  10 . The structure of the dispenser actuator assembly  100  will first be described followed by a description of the cooperation and operation of the dispenser actuator assembly  100  with the dispenser  10 . 
     As further shown in  FIGS.  9 - 18   , the dispenser actuator assembly  100  generally includes a base member  102  and an actuator assembly  104 . The actuator assembly  104  is operably connected to the base member  102  as further described below. 
       FIGS.  9 - 16    show the base member  102  of the dispenser actuator assembly  100 . The base member  102  is generally a rounded member that fits around at least a portion of the glass ampoule assembly  10 . The base member  102  is further an annular member that in one exemplary embodiment is dimensioned to fit over the dispenser or glass ampoule assembly  10  as described in greater detail below. 
     The base member  102  generally includes an annular ring member  106  and a connector member  108 . The annular ring member  106  is a full ring member in an exemplary embodiment that defines an opening  110  therethrough to receive the dispenser as explained in greater detail below. Thus, in an exemplary embodiment, the annular ring member  106  is dimensioned to fit circumjacently around the glass ampoule assembly and, in particular, the second container  14 . It is understood that in other exemplary embodiments, the ring member  106  may not be a full ring member and have an interruption, slot or break in the member. The annular ring member  106  has an inner surface  112  that defines the opening  110 . The inner surface  112  has a plurality of ribs  114  extending radially inwardly into the opening  110 . In an exemplary embodiment, the ribs  114  extend axially or longitudinally along the inner surface  112  of the annular ring member  106 . Furthermore, four ribs  114  are utilized and are spaced circumferentially on the inner surface  112  at 12 o&#39;clock, 3 o&#39;clock, 6 o&#39;clock and 9 o&#39;clock positions. It is further understood that a single rib  114  could be employed or other numbers of ribs  114 , and further at other annular locations. The ribs  114  could also take the form of ribs extending circumferentially along the inner surface  112  of the annular ring member  106 . The ribs  114  assist in providing an interference fit with the second container  14  of the glass ampoule assembly  10  when the base member  102  is mounted on the second container  14 . The annular ring member  106  further has a flange  116  extending circumferentially around the ring member  106  at a proximate end of the ring member  106 . The flange  116  assists in adding rigidity and strength to the proximal end of the base member  102 . The added rigidity and strength provided by the flange  116  also helps when ejector pins push the base member  102  off of the mold member during the injection molding process. 
       FIGS.  9 - 16    further show the connector member  108  of the base member  102 . The connector member  108  generally connects to the actuator assembly  104 . The connector member  108  extends from a proximate end of the annular ring member  106  towards the actuator assembly  104 . The connector member  108  has a first slot  118  or upper slot  118  defined therein as well as a second slot  120  or lower slot  120  defined therein. As a result, the connector member  108  has a first segment  122  and a second segment  124  defined between the first slot  118  and the second slot  120 . The first segment  122  is positioned generally opposite to the second segment  124 . The first slot  118  and the second slot  120  extend partially circumferentially having respective ends that confront in spaced relation to define the first segment  122  and the second segment  124 . The first slot  118  and the second slot  120  are generally opposite to one another. As explained in greater detail below, the slots  118 , 120  assist in the flexing of the actuator assembly  104 , or pivoting movement of the actuator assembly  104 . The first segment  122  has a first end connected to the base member  102  and a second end connected to the actuator assembly  104 , or a flex plate of the actuator assembly to be described. The second segment  124  has a first end connected to the base member  102  and a second end connected to the actuator assembly  104 , or a flex plate of the actuator assembly to be described. The second segment  124  has a second raised tab  126  positioned on a central portion of the first segment  122  and that extends from the flange  116  towards the actuator assembly  104  (or to a flex plate as described in greater detail below). Similarly, the second segment  124  has a second raised tab  128  positioned on a central portion of the second segment  122  and that extends from the flange  116  to the actuator assembly  104 . The raised tabs  126 , 128  assist in providing rigidity for an enhanced connection between the base member  102  and the actuator assembly  104 . The rigidity provided by the raised tabs  126 , 128  further help when ejector pins engage the base member  102  proximate the raised tabs  126 , 128  to smoothly remove the assembly  100  from a mold member after formation in an injection molding process. 
     As shown in  FIGS.  9 - 16   , the base member  102  is formed as a full annular ring member in one exemplary embodiment. The base member  102  is designed to receive or hold the dispenser  10  or glass ampoule assembly  10 , and it is understood that the base member  102  may not have a full ring-shaped configuration. For example, the base member  102  can have certain segments eliminated and not utilized while still having a configuration to receive or hold the glass ampoule assembly  10 . The base member  102  could have a slot formed therein to define separate segments that may be resiliently flexible. 
     The base member  102  further defines the annular ring member  106  that defines the opening  110  for the glass ampoule assembly  10 . The inner surface  112  of the base member  102  is tapered such that the entry of the base member is slightly larger at one end. In a particular exemplary embodiment, the base member  102  tapers to a larger dimension towards the actuator assembly  104 . This provides for easier insertion of the glass ampoule assembly at that end. In one exemplary embodiment, there is a 2-degree taper of the inner surface  112 . In other exemplary embodiments, the taper could be 1-3 degrees. It is further understood that the taper can be in an opposite direction as well. The outer container  14  of the glass ampoule assembly  10  may have a rounded end that also assists insertion/mounting between the dispenser actuator assembly  100  and the glass ampoule assembly  10 . 
       FIGS.  9 - 16    further show the actuator assembly  104  of the dispenser actuator assembly  100 . In one exemplary embodiment, the actuator assembly  104  generally includes a first actuator arm  132   a  and a second actuator arm  132   b.  As explained in greater detail below, the first actuator arm  132   a  and the second actuator arm  132   b  are connected to the base member  102  via the connector member  108  and, in particular, the first segment  122  and the second segment  124  of the connector member  108 . It is understood that the first actuator arm  132   a  and the second actuator arm  132   b  are similar in structure and positioned generally symmetrically as described in greater detail below. The first actuator arm  132   a  and the second actuator arm  132   b  extend from the base  102  (or flex plate to be described) in generally opposed relation. It is also understood that description regarding the first actuator arm  132   a  will generally apply to the second actuator arm  132   b.  The structures of the first actuator arm  132   a  are referenced with an “a” designation while the structures of the second actuator arm  132   b  are referenced with a “b” designation. 
       FIGS.  9 - 16    further show the first actuator arm  132   a.  The first actuator arm  132   a  has a proximal end  134   a,  a distal end  136   a  and an intermediate segment  138   a.  The proximal end  134   a  is angled to be generally parallel to the flange  116 . The proximal end  134   a  is connected to the first segment  122  of the connector member  108  and the second segment  124  of the connector member  108 . As shown further in  FIGS.  9  and  10   , the intermediate segment  138   a  defines a floor segment  140   a  and an outer peripheral flange  142   a.  The floor segment  140   a  is recessed with respect to the outer peripheral flange  142   a.  The intermediate segment  138   a  has a plurality of apertures  144   a  extending into the first actuator arm  132   a  proximate the proximal end  134   a.  In an exemplary embodiment, the apertures  144   a  do not extend entirely through the arm  132   a.  The apertures  144   a  assist in removing certain material in the formation of the assembly  100  to avoid having large block of material associated with the assembly  100  which is generally undesirable in an injection molding process used to form the assembly  100 . The apertures  144   a  further define additional walls to add further rigidity and strength to the assembly  100 . The floor segment  140   a  further has a finger pad  146   a  in the form of a plurality of raised ridges  148   a.  The recessed features of the floor and ridges with respect the flange provide for a tactile feel for the user for more proper finger/digit placement, as well as helping to maintain engagement of the fingers/digits with the actuator arms  132   a,   132   b.  It is understood that the structures of the first actuator arm  132   a  apply to the second actuator arm  132   b  with the “b” designations. 
     As shown in  FIGS.  9 - 22   , the first actuator arm  132   a  further has a depending protrusion  150   a  positioned on an underside of the first actuator arm  132   a.  The depending protrusion  150   a  has a first segment  152   a  and a second segment  154   a.  The first segment  152   a  defines a platform  156   a  proximate to the proximal end of the first actuator arm  132   a.  The second segment  154   a  extends from the first segment  152   a  at an interface edge  158   a.  The interface edge  158   a  may be considered as defining a lined projection to be described in greater detail below. The lined projection is useful in providing a concentrated force against the glass ampoule assembly  10  as described in greater detail below. The second segment  154   a  has a plurality of channels  160   a  defined therein wherein the second segment  154   a  defines a plurality of spaced walls  162   a.  In an exemplary embodiment, the second segment  154   a  has a pair of channels  160   a  that define three spaced walls  162   a.  The walls  162   a  add stiffness to the actuator arm  132   a.  The second segment  154  and the walls  162   a  are dimensioned such that they follow the extension of the first actuator arm  132   a.  The second segment  154   a  inclines upward towards the distal end  136   a  of the arm  132   a,  thus the second segment  154   a  defines an inclined surface. As explained in greater detail below, this configuration allows the second segment  154  to be generally parallel to a longitudinal axis of the glass ampoule assembly  10  when a user manipulates material from the assembly  10  by further squeezing the actuator arm  132   a.  With the walls  162   a  depending from an underside surface of the floor segment  140   a  of the actuator arm  132   a,  the actuator arm  132   a  is designed similar to an I-beam wherein the structure provides strength, rigidity and stiffness to the actuator arm  132   a.  The walls  162  depend from an underside surface of the actuator arm  132   a.  The top of the actuator arm  132   a  remote from the proximal end remains a solid structure without openings to provide tactile feel while the spaced walls  162   a  provide strength etc. to the actuator arm  132   a.    
     As shown in  FIG.  15   , a boss  164   a  is defined at a distal end of the second segment  154   a  of the depending protrusion  152   a.  In an exemplary embodiment, a boss  164   a  is defined at the distal end of each spaced wall  162   a.  The boss  164   a  is configured to be engaged by ejector pins in ejecting the molded part from a mold during an injection molding process used to form the dispenser actuator assembly  100  as described in greater detail below. As further shown in  FIGS.  15  and  16   , an indentation  166   a,  or indentation slot  166   a  is defined in the actuator arms  132   a  adjacent the bosses  164   a.  The indentation  166   a  is generally defined between an underside surface of the actuator arm  132   a  and the boss  164   a.  As described in greater detail below, during the injection molding process used to form the assembly  100 , fingers defined in the mold part extend into the mold cavity to define the indentations  166   a.  The fingers will maintain the actuator arms  132   a,   132   b  against an internal mold part until ejector pins can engage the bosses  164   a.  This minimizes the chance for the actuator arms  132   a,   132   b  to prematurely come off of the internal mold piece which could affect later operation of the assembly. The shape of the second segment  154   a  allows the second segment  154   a  to manipulate the glass ampoule assembly  10  to provide an enhanced pumping action to expel more fully the flowable material M from the glass ampoule assembly. As discussed, the above description of the structure of the first actuator arm  132   a  is applicable for the structure of the second actuator arm  132   b  and having “b” designations. 
     The dispenser actuator assembly  100  is used with a dispenser  10  such as the glass ampoule assembly  10  to crush the glass ampoule assembly  10  and dispense flowable material from the glass ampoule assembly  10 . As can be appreciated from  FIG.  8   , the glass ampoule assembly  10  is prepared such as by removing a cardboard sleeve if the sleeve is being used or removing the glass ampoule assembly  10  from any blister packaging. Alternatively, the glass ampoule assembly  10  may use the cover member  18  which is removed in preparation for dispensing flowable material from the glass ampoule assembly  10 . As can be appreciated from  FIGS.  29 - 34   , the glass ampoule assembly  10  is inserted into the base member  102 . The opening  110  defined by the base member  102  receives the glass ampoule assembly  10  wherein the base member  102  slides onto the second container  14 . Thus, the actuator assembly  100  is slidably movable along the second container  14 . In one exemplary embodiment, the base member  102  slides onto the second container  14  in a frictional interference fit. The ribs  114  assist in engaging the outer surface of the outer container  14  of the glass ampoule assembly  10  to achieve a snug interference fit. In one exemplary embodiment, the glass ampoule assembly  10  is inserted into a distal end of the base member  102  opposite the flange  116 . Even if the taper is such that the distal end of the base member  102  is more narrow, the outer container  14  of the glass ampoule assembly  10  has a rounded edge that assists in smooth insertion/mounting. It is also understood that the dispenser actuator assembly  10  could also be slid over the glass ampoule assembly  10  at the proximal end of the base member  102 . Regardless of the insertion, the actuator arms  132   a,   132   b  extend away from the applicator  16  of the ampoule assembly  10 . 
     As further shown in  FIGS.  29 - 30   , when the dispenser actuator assembly  100  is properly located on the glass ampoule assembly, the first depending protrusion  150   a  and the second depending protrusion  150   b  are positioned proximate the first interface area  28  of the glass ampoule  12 . In particular, the interface edge  158   a  of the first depending protrusion  150   a  and the interface edge  158   b  of the second depending protrusion  150   b  are positioned at the first interface area of the first container  12  of the glass ampoule assembly  10 . In addition, the first actuator arm  132   a  and the second actuator arm  132   b  extend towards the closed end  38  of the second container  14  of the glass ampoule assembly  10 . 
     It is understood that the one of the dispenser actuator assembly  100  and the glass ampoule assembly  10  could have a locating structure thereon to properly position the dispenser actuator assembly  100  on the glass ampoule assembly  10  so that the actuator arms  132   a,   132   b  are properly positioned to crush the glass ampoule  12 . The location structure can also take the form of a cooperative structure on one of or both of the dispenser actuator assembly  100  and the glass ampoule assembly  10 . For example, the second container  14  of the glass ampoule assembly  10  could have an annular, radially-inwardly formed indentation that the base member  102  is received therein to automatically locate the dispenser actuator assembly  100  on the proper location on the glass ampoule assembly  10 . Similarly, an outwardly extending protrusion could be located on the second container wherein the base member  102  slides over the protrusion until the actuator assembly  100  fits adjacent the protrusion to be properly located. Multiple protrusions could also be used such as outwardly extending spaced protrusions wherein the actuator assembly  100  fits within spaced protrusions to be properly located. 
       FIGS.  29  and  30    show the dispenser actuator assembly  100  positioned on and operably connected to the glass ampoule assembly  10 . The glass ampoule assembly  10  is now ready to be actuated. The first container  12 , or glass ampoule  12 , is in a position to be crushed wherein the flowable material M can be dispensed from the assembly  10 . As further shown in  FIG.  29   , the first depending protrusion  150   a  of the first actuator arm  132   a  and the second depending protrusion  150   b  of the second actuator arm  132   b  are spaced from the second container  14  and positioned over and proximate the first interface area  28 . Thus, a gap or space is initially maintained between the protrusions  130   a,   130   b  and the second container  14 . In such position as shown in  FIG.  29   , the actuator arms  132   a,   132   b  are in a first position, or first neutral position NP. 
     As can be further appreciated from  FIGS.  29 - 30   , a user holds the dispenser actuator assembly  100  wherein a forefinger wraps around an underside of the base member  102  and engages the second actuator arm  132   b.  A thumb of the user engages the first actuator arm  132   a.  In particular, a user&#39;s forefinger and thumb engage the respective finger pads  146   a,   146   b  of the first actuator arm  132   a  and the second actuator arm  132   b.  The user squeezes the actuator assembly  100  thereby applying a compressive force F ( FIG.  30   ) to the first actuator arm  132   a  and the second actuator arm  132   b.  Thus, the actuator arms  132   a,   132   b  are pivotable about the base  102  from the first neutral position to a second position or an actuating position AP. In response to this compressive force, the depending protrusion  150   a  of the first actuator arm  132   a  is deflected towards and engages the second container  14  and the depending protrusion  150   b  of the second actuator arm  132   b  is deflected towards and engages the second container  14 . As the user continues to depress the first actuator arm  132   a  and the second actuator arm  132   b,  the depending protrusion  150   a  of the first actuator arm  132   a  deflects the second container  14  wherein the second container  14  engages the glass ampoule  12  at proximate a top or upper portion of the first interface area  28 , and the depending protrusion  150   b  of the second actuator arm  132   b  deflects the second container  14  wherein the second container  14  engages the glass ampoule  12  at proximate a bottom or lower portion of the first interface area  28  (e.g. opposite ends of the first interface area  28 ), wherein the glass ampoule  12  is crushed at the first interface area  28 . In particular, it is understood that the first interface area  28  is engaged by the protrusion interface edge  158   a,   158   b  (ridge) of the protrusions  150   a,   150   b  of the actuator arms  132   a,   132   b.  The protrusion interface edges  158   a,   158   b  assist in concentrating the force F onto the outer container  14  and glass ampoule  12 . 
     It is further understood that the first slot  118  or upper slot  118  and the second slot  120  or lower slot  120  assist on providing sufficient flexibility for the actuator arms  132   a,   132   b.  As the slots  118 , 120  separate the actuator arms  132   a,   132   b  from the base member  102 , the actuator arms  132   a,   132   b  can pivot independently from the base member  102 . This allows the base member  102  to continue to provide support for holding the glass ampoule assembly  10  independently of the pivoting of the actuator arms  132   a,   132   b.  It is further understood that the actuator arms  132   a,   132   b  themselves do not generally bend or flex as the arms  132   a,   132   b  are more rigid, but the arms  132   a,   132   b  flex or pivot. Upon crushing or rupture, the flowable material M passes from the glass ampoule  12  and into the applicator  16 . Because force F is applied to the glass ampoule  12  at the first interface area  28 , the domed portion of the glass ampoule  12  breaks into multiple pieces allowing enhanced flow of the flowable material M out of the glass ampoule  12  and into the second container  14  and to the applicator assembly  16 . It has been determined by the inventors that if the glass ampoule  12  is crushed at the interface area  28 , the domed-section will break into multiple pieces rather than remaining intact while breaking away from the intermediate section of the glass ampoule  12 . The flowable material M passes from the second container  14  and into the applicator assembly  16 .  FIGS.  31  and  32    disclose partial views of the actuation of the glass ampoule assembly  10  wherein the depending protrusions  150   a,   150   b  of the first and second actuator arms  132   a,   132   b  engage the second container  14  of the glass ampoule assembly  10 . 
     As further can be appreciated from  FIGS.  30  and  33   , the user can continue to squeeze the actuator assembly  100  wherein the user engages the first actuator arm  132   a  and the second actuator arm  132   b  thereby continuing to apply the compressive force F wherein the depending protrusions  150   a,   150   b  are further deflected towards and engage the second container  14 . As the user continues to depress first and second actuator arms  132   a,   132   b,  the respective second segments  154   a,   154   b  of the protrusions  150   a,   150   b  deflect the second container  14  wherein the second container  14  engages the glass ampoule  12  further along the glass ampoule  12 . In this configuration such as shown in  FIG.  33   , the respective segments  154   a,   154   b  are generally positioned parallel to one another. In certain embodiments, the glass ampoule  12  may be sized such that the respective second segments  154   a,   154   b  can be positioned at proximate the second interface area  30  wherein the glass ampoule  12  further ruptures. Upon this additional rupture, the flowable material M more easily passes from the glass ampoule  12  and into the second container  14  and into the applicator  16 . Because force F is applied to the glass ampoule  12  at the second interface area  30 , the domed portion of the glass ampoule  12  breaks into multiple pieces allowing enhanced flow of the flowable material M out of the glass ampoule  12  and into the second container  14  and to the applicator assembly  16 . It is further understood that the user can use the actuator arms  132   a,   132   b  and second segments  154   a,   154   b  to further deflect and manipulate the second container  14  and force the flowable material M through the applicator assembly  16  and, therefore, to enhance dispensing of the flowable material M from the glass ampoule assembly  10 . 
     It is understood that the applicator assembly  16  assists in minimizing the chance of glass shards from the ruptured glass ampoule  12  from passing out of the glass ampoule assembly  10 . In addition, the outer wall of the second container  14  prevents glass shards from cutting fingers of the user thereby protecting the user&#39;s fingers from injury by the fractionated glass shards of the glass ampoule  12  that remain in the second container  14 . Because a user engages the actuator assembly  100  to crush the glass ampoule assembly  10  rather than engaging the glass ampoule assembly  10  directly, the chance of cutting a user&#39;s fingers/thumb from glass shards is further minimized. It is understood that additional structures could be incorporated into the glass ampoule assembly  10  such as filter assemblies  44  to minimize the chance of glass shards from passing through the applicator assembly. As shown in  FIG.  34   , the flowable material M can be dispensed from the glass ampoule assembly  10  and onto a receiving surface. The receiving surface S can vary depending the particular type of flowable material M being dispensed. In one exemplary embodiment, the flowable material M may be a medicine that is dispensed onto a skin surface S of a patient. 
     As further appreciated from the figures, the user dispenses the flowable material M from the glass ampoule assembly  10  with the aid of the dispenser actuator assembly  10 . Once the flowable material M is emptied from the glass ampoule assembly  10 , the dispenser actuator assembly  100  can be removed from the glass ampoule assembly  10 . In this fashion, the dispenser actuator assembly  10  can be reused with multiple dispenser assemblies  10  or glass ampoule assemblies  10 . In this configuration, the dispenser actuator assembly  100  can be formed from a more robust and higher-cost material. In other configurations, the material used to form the dispenser actuator assembly  100  could be a lower cost material that is designed as a one-time use wherein the dispenser actuator assembly  100  is disposable. In such case, the location structured used to position the dispenser actuator assembly  100  on the glass ampoule assembly  10  could be structured to permanently attach the dispenser actuator assembly  100  to the glass ampoule assembly  10 . Once the flowable material M is fully dispensed from the glass ampoule assembly, the attached structures can be simply discarded together. 
     It is understood that the dispenser actuator assembly  100  can be formed in an injection molding process to form a unitary one-piece member. A wide variety of materials can be used to form the dispenser actuator assembly  100  wherein the actuator arms  132   a,   132   b  are resiliently pivotable to actuate the glass ampoule assembly and then be reused on additional glass ampoule assemblies. As discussed, it is understood that in an exemplary embodiment, the actuator arms  132   a,   132   b  are generally rigid and do not bend or flex themselves, but rather pivot about the connector members or in relation to the base member  102 . Similarly, the depending protrusions  150   a,   150   b  are rigid and do flex themselves. In an exemplary embodiment, the dispenser actuator assembly is made from one of the polyolefin family of resins. 
     As discussed herein, the dispenser actuator assembly  100  has been described herein as having a base member  102  and an actuator assembly  104  having a first actuator arm  132   a  and a second actuator arm  132   b.  A connector member  108  has been described that connects the base member  102  and the actuator assembly  104 . It is understood that the actuator arms  132   a,   132   b  pivot towards one another, and pivot with respect to the base member  102  and connector member  108 . It is understood that the assembly  100  could also be considered that the first actuator arm  132   a  and the second actuator arm  132   b  are connected by a central hub member  180  or flex plate  180 , or torsion plate  180 . In particular, a proximal end  134   a  of the first actuator arm  132   a  is connected to a top portion or first end of the flex plate  180 , and a proximal end  134   b  of the second actuator arm  132   b  is connected to a bottom portion or second end of the flex plate  180 . The first end of the flex plate  180  is generally opposite to the second end of the flex plate  180 . In one exemplary embodiment, the flex plate  180  is then considered to be part of the actuator assembly  104 . The flex plate  180  is generally connected between the actuator arms  132   a,   132   b  and, as discussed, the first end, or upper end of the flex plate  180  is connected to the proximal end  134   a  of the first actuator arm  132   a,  and an opposite second end, or lower end of the flex plate  180  is connected to the proximal end  134   b  of the second actuator arm  132   b.  In this configuration, the base member  102  is still operably connected to the actuator assembly  104  by the connector member  108 . The flex plate  180  serves as a transition structure from the base member  102  to the actuator arms  132   a,   132   b.    
       FIG.  18    shows the flex plate  180  in greater detail. The flex plate  180  has a central portion  182  and a first side rail  184  and a second side rail  186 , generally opposite the first side rail  184 . The central portion  182  of the flex plate  180  has an opening  188  therethrough. The flex plate opening  188  is generally aligned with the opening  110  of the base member  102  as further described below. The flex plate opening  188  may be slightly larger than the opening  110  of the base member  102  or the same size. Thus, the flex plate opening has a diameter larger than a diameter of the opening of the base member  102 . The central portion  182  further has a first flexion segment  190  or upper flexion section  190 , and a second flexion segment  192  or lower flexion segment  192  as further described below. An upper portion of the first flexion segment  190  is adjacent the proximal end  134   a  of the first actuator arm  132   a  at a first connection line  194 , generally at the first end of the flex plate  180 . A bottom portion of the second flexion segment  192  is adjacent the proximal end  134   b  of the second actuator arm  132   b  at a second connection line  196 , generally at the second end of the flex plate  180 . As further shown in  FIG.  18   , the central portion  182  of the flex plate  180 , including the first flexion segment  190  and the second flexion segment  192 , have a lesser thickness than the thickness of the first side rail  184  and the second side rail  186 . As further shown in  FIGS.  29  and  33   , it is understood that the first flexion segment  190  is positioned generally between a midpoint of the vertical length of the flex plate  180  and the location where the first actuator arm  132   a  is connected to the flex plate  180 . Similarly, the second flexion segment  192  is positioned generally between a midpoint of the vertical length of the flex plate  180  and the location where the second actuator arm  132   b  is connected to the flex plate  180 . The flex plate  180  generally flexes or bends at positions between where the connector member  108  connects to the flex plate (the first segment  122  and the second segment  124 ) and where the actuator arms  132   a,   132   b  connect to the flex plate  180 . As discussed, the first slot  118  is defined between the first end of the flex plate  180  and the base  102 . The second slot  120  is defined between the second end of the flex plate  180  and the base  102 . 
     As can be further appreciated from  FIG.  18   , the flex plate  180  is connected to the first actuator arm  132   a  and the second actuator arm  132   b.  In this exemplary embodiment of the invention, the flex plate  180  and the first actuator arm  132   a  and the second actuator arm  132   b  define the actuator assembly  104 . The upper portion of the first flexion segment  190  and upper portions of the first and second side rails  184 , 186  are connected to the proximal end  134   a  of the first actuator arm  132   a  at the first connection line  194 . Similarly, the lower portion of the second flexion segment  192  and lower portions of the first and second side rails  184 , 186  are connected to the proximal end  134   b  of the second actuator arm  132   b.  As further shown in  FIG.  18   , the first segment  122  of the connector member  108  is connected to the central portion of the flex plate  180  and also to the base  102 . Thus, the first segment  122  has a first end connected to the base  102  and a second end connected to the flex plate  180 . The first raised tab  126  is connected to the first side rail  184  and also connected to the flange  116  of the base  102 . The second segment  124  of the connector member  108  is connected to the central portion of the flex plate  180  and also to the base  102 . Thus, the second segment  124  has a first end connected to the base  102  and a second end connected to the flex plate  180 . The second raised tab  128  is connected to the second side rail  186  and also to the flange  116  of the base  102 . With these connections, the flex plate opening  188  is generally aligned with the opening  110  of the base member  102 . Accordingly, the connector member  108  operably connects the base member  102  to the actuator assembly  104 . As discussed, the segments  122 , 124  of the connector member  108  are connected to the flex plate  180 . It is further understood that the flex plate  180  could have location structures thereon to properly position the dispenser actuator assembly  100  on the glass ampoule assembly  10 . It can further be appreciated from  FIGS.  18  and  31   , for example, that the flex plate  180  is dimensioned to extend beyond the outer periphery of the base member  102 . 
     As previously discussed and as shown in  FIGS.  17  and  29   , the dispenser actuator assembly  100  is mounted on the glass ampoule assembly  10  and in a position wherein the protrusions  150 , 152  can crush the glass ampoule  12 . This configuration may be considered the first position or neutral position. In this configuration, the flex plate  180  is unflexed and is generally in a planar configuration such as shown in  FIGS.  17  and  29   . Similar to the description above, a user engages the first actuator arm  132   a  and the second actuator arm  132   b  and applies a force F wherein the arms  132   a,   132   b  are forced towards one another. Thus, the arms  132   a,   132   b  move from the first neutral position to an actuating position AP. The flex plate  180  flexes generally at the first flexion segment  190  and the second flexion segment  192 . This flexion of the flex plate  180  is shown in  FIGS.  30 - 33   . The first flexion segment  190  and the second flexion segment  192  provides for flexion over a greater radius, which lessens the stress on the assembly  100 . If the actuator arms  132   a,   132   b  pivoted specifically at, for example, the first connection line  194  and the second connection line  196 , stresses are more locally focused at a smaller area, which is undesirable as it can promote plastic deformation of the material. The first flexion segment  190  and the second flexion segment  192  provide elastic deformation of the flex plate  180 , which allows the flex plate  180  to return to its first or neutral position NP. Thus, the flex plate  180  is resiliently deflectable.  FIG.  31    shows the flexion of the first flexion segment  190  and the second flexion segment  192  represented by the angular configuration “A” and which further provides for the majority of the flexing of the flex plate  180 . Additional arrows A in  FIG.  31    further show the flexion of the flex plate  180 . It is understood that the actuator arms  132   a,   132   b  are generally more rigid and do not pivot around the first connection line  194  and the second connection line  196 . The flexion is concentrated at the flex plate  180  as shown. 
     As further shown in  FIG.  33   , a user can continue to press the actuator arms  132   a,   132   b  to manipulate flowable material from the glass ampoule assembly  100  wherein the second segments  154   a,   154   b  of the actuator arms  132   a,   132   b  are configured to be generally parallel to one another to further deform the outer container  14  of the glass ampoule assembly  10 . Furthermore, the walls  162   a,   162   b  engage the outer container  14  and further manipulate the glass ampoule  12  wherein the walls  162   a,   162   b  are generally parallel to the longitudinal axis of the glass ampoule assembly  100 . It is further understood that the dispenser actuator assembly  10  can be slid along the outer container  14  to reposition the assembly  10  and further manipulate the outer container  14  with the second segments  154   a,   154   b  to expel flowable material M from the assembly  10 . 
     The base member  102  utilizing the slots  118 , 120  or the flex plate  180  and slots  118 , 120  provides structural and functional advantageous features. As discussed, the actuator arms  132   a,   132   b  do not pivot or flex towards one another at a specific point or location. The flex plate  180  flexes as shown in  FIGS.  30 - 33    and such flexing occurs over a greater distance, e.g., a more substantial distance associated with the flex plate  180 . In particular, much of the bending or flexing occurs at the first flexion segment  190  and the second flexion segment  192 . This distributes stresses associated with the flexing over a greater distance on the flex plate  180  as opposed to a flexing configuration at a point such as a living hinge. With flexing and distributed stresses over a greater distance, any breaking point is minimized wherein the material of the assembly  100  is not pushed past its elastic limits. This allows the actuator arms  132   a,   132   b  to return to the first or neutral position NP wherein the assembly  100  can be used with further glass ampoule assemblies  10 . If the flexing structure was a living hinge structure, force would be focused at a more localized point, which would promote a failure or breaking of the actuator arm  132   a,   132   b  from the base member  102 . This configuration further provides for substantially rigid actuator arms  132   a,   132   b  that have little flexing from the arms  132   a,   132   b  themselves. While the material of the actuator arms  132   a,   132   b  provide for minimal flexing, the flex plate  180  flexes to allow the substantially rigid actuator arms  132   a,   132   b  to pivot or move towards one another, which allows for the depending protrusions  150   a,   150   b  to provide a more direct, localized force to the glass ampoule assembly  10 . This configuration also provides for flexing/movement of the actuator arms  132   a,   132   b  independently of the support of the outer container  14  by the base member  102 . The base member  102  supports the outer container  14  of the glass ampoule assembly  10  as the outer container  14  is inserted through the base member  102 . With the slots  118 , 120  and the flex plate  180 , the actuator arms  132   a,   132   b  pivot via the flexing of the flex plate  180 , which is independent of the support the base member  102  provides to the outer container  14 . In other designs where wings or arms project directly from or an integral connection to a base, the base member can distort or deform in response to the movement of the arms  132   a,   132   b.  As a result, the support for the ampoule assembly  10  can be lessened, altered or otherwise adversely affected. With the present design, the support of the glass ampoule assembly  10  by the base member  102  is isolated from the actuator arms  132   a,   132   b  and not affected by the movement of the actuator arms  132   a,   132   b.    
     Finally, the structural features of the flex plate  180  and actuator arms  132   a,   132   b  minimize unwanted lateral movement of the actuator arms  132   a,   132   b.  The actuator arms  132   a,   132   b  are connected laterally across the entire lateral dimension of the flex plate  180 , e.g., the first and second connection lines  194 , 196 , which connection generally resists lateral movement of the actuator arms  132   a,   132   b.  Minimizing any lateral movement of the actuator arms  132   a,   132   b  is desirable as it can affect the proper crush of the glass ampoule  12  as the protrusion  150   a,   150   b  may slip to the side of the glass ampoule  12  preventing crushing. As shown in  FIG.  13   , the base member  12  supports the glass ampoule assembly  10  across a lateral distance “a” that may generally correspond to a diameter of the glass ampoule assembly  10 , e.g. a diameter dimension. The actuator arms  132   a,   132   b  are connected along connection lines  194 , 196  across a lateral dimension “b” that is greater than the diameter dimension “a.” Thus, the lateral dimension of the flex plate  180  extends beyond the diameter of the glass ampoule assembly  10 . With a greater dimension “b”, the actuator arms  132   a,   132   b  move towards the glass ampoule assembly in a generally perpendicular or normal direction to the elongated longitudinal axis L ( FIG.  33   ) of the glass ampoule assembly  10 . These structural and functional features of the dispenser actuator assembly  100  provide benefits over prior assemblies. 
     As discussed, in an exemplary embodiment, the dispenser actuator assembly  100  is formed as a single unit in an injection molding process.  FIGS.  19 - 28 B  disclose multiple mold members used to injection mold the dispenser actuator assembly  100 .  FIGS.  19 - 23    disclose a core mold member  200  used in making the dispenser actuator assembly  100 .  FIGS.  24 - 25    show an upper mold member  202  and a lower mold member  204 . The core mold member  200 , the upper mold member  202  and the lower mold member  204  are positioned in adjacent spaced relation to cooperate to define and form a mold cavity  206  ( FIG.  24 A ) to receive the injected molded material. It is understood that additional mold members can be used as well as other structures and mechanisms such as gates known in the art of injection molding. 
       FIGS.  19 - 22    show the core mold member  200 . The core mold member  200  has a central post  208  extending from a main body  210  having inclined surfaces  212  each having slotted indentations  214 . The central post  208  helps form the base member  102  and the slotted indentations  186  help form portions of the actuator assembly  104 . The central post  208  has channels  209  therein corresponding to the longitudinal ribs  114  on the base  102 . It is understood that the central post  208  may be designed to be screwed into the main body  210  or otherwise removably attached to the main body  210 . In such design, the central post  208  can comprise multiple types of central posts  208  each having channels  209  of different depths. In such case, the longitudinal ribs  114  can be made of varying sizes to accommodate differently-sized glass ampoule assemblies  10 . The main body  210  has certain openings or conduits through the body  210  used to assist in ejecting the form part at the end of the injection molding process. As shown in  FIG.  23   , the main body  210  has pair of finger projections  216   a,   216   b  that extend toward the central post  208 . 
       FIGS.  24 - 25    further show the upper mold member  202  and the lower mold member  204 . The mold members  202 , 204  are positioned adjacent and in spaced relation to the core mold member  200  to define the mold cavity  206 . It is understood that the mold members  200 - 204  cooperate to correspond to surfaces of the dispenser actuator assembly  100 . For example, the core mold member  200  and portions of the upper mold member  202  and the lower mold member  204  cooperate to define the first and second actuator arms  132   a,   132   b.  The finger projections  216   a,   216   b  on the core mold member  200  extend into the mold cavity  206 . 
     As discussed, the mold members  200 , 202 , 204  cooperate with a gate that receives a source of injection molded material and delivers the material into the mold cavity  206 .  FIG.  24 B  schematically shows molded material MM in the process of being injected into the mold cavity  206 . It is understood that the molded material MM is injected into the entire mold cavity  206  to form the dispenser actuator assembly  100 . It is understood that the molded material MM cools and hardens in the mold cavity  206  wherein the dispenser actuator assembly  100  is formed. Once formed and properly cooled, the dispenser actuator assembly  100  can be removed from the mold. 
     It is understood that the dispenser actuator assembly  100  is formed in the mold cavity including the first actuator arm  132   a  and the second actuator arm  132   b.  As shown in  FIG.  25   , the upper mold member  202  and the lower mold member  204  are spaced away from the core mold member  200 . It is desirable for the actuator arms  132   a,   132   b  to maintain contact with the core mold member  200  until the assembly  100  can be ejected from the core mold member  200 . With such movement of the mold members  202 , 204 , the actuator arms could “stick” to the mold members  202 , 204  where the actuator arms  132   a,   132   b  will pivot upwards following movement of the mold members  202 , 204 . This premature flexing of the actuator arms  132   a,   132   b  will have a detrimental effect on operation of the actuator arms in actuating a dispenser  10 .  FIGS.  26 - 27 B  show the dispenser actuator assembly  100  still on the core mold member  200  after removal of the upper mold member  202  and the lower mold member  204  (The mold members  202 , 204  are not shown for clarity.). As previously discussed, the finger projections  216   a,   216   b  extend into the mold cavity  206 . The finger projections  216   a,   216   b  are positioned above the bosses  164   a,   164   b  and, therefore, keep the actuator arms against the core mold member  200 . The finger projections  216   a,   216   b  are positioned between the bosses  164   a,   164   b  and the underside surface of the actuator arms  132   a,   132   b.  As can be appreciated from  FIGS.  28 A and  28 B , ejector pins are inserted through passageways in the core mold member  200  to engage the bosses  164   a,   164   b  and eject the assembly  100  from the core mold member  200 . As shown in  FIG.  28 B , the finger projections  216   a,   216   b  are removed from the respective indentations  166   a,   166   b  of the assembly  100 . Once removed, it is understood that the indentation slots  166   a,   166   b  are revealed. The dispenser actuator assembly  100  is then properly formed and ready for further processing and use. 
     It is understood that additional features can be incorporated into the molding process. The gates for injecting molded material MM into the mold cavity  206  can be varied to achieve desired characteristics in the assembly. In a further exemplary embodiment, a multi-shot molding process could be utilized. For example, a two-shot molding process could be utilized wherein the flex plate structure is molded from a more flexible material while other structures of the assembly  100  such as the base member  102  and the actuator assembly  104  are formed from a more rigid material. 
     The dispenser actuator assembly  100  can be formed in the injection molding process from a variety of different injected molded materials. Selection of the material will depend on the desired operational characteristics of the assembly  100  such as the amount of rupturing force to be generated. The assembly  100  could be formed from polyolefin family of resins. The material could be polyethylene or polypropylene and a combination thereof. The material could also be nylon. Because of the structural features described above, it is possible to use more rigid/brittle materials as well as materials having a higher flexural modulus. The material could also be amorphous polymers including acrylic, acrylonitrile butadiene styrene, or polycarbonate. The material for the assembly  100  could further be a polyvinylidene fluoride (PVDF) material. With the broader selection of materials possible, the assembly  100  can also be used in a broader range of applications requiring rupturing of different types of containers. The dispenser actuator assembly  100  could also be made of materials for specialty application such as materials that are capable of being autoclavable. 
     It is understood that the dispenser actuator assembly  100  can have certain modified structures to enhance the operability of the assembly  100 . 
       FIGS.  35 - 36    disclose another alternative embodiment of the dispenser actuator assembly  100  according to an exemplary embodiment of the invention. The structure of the dispenser actuator assembly  100  of  FIGS.  35 - 36    is similar to the structure of the dispenser actuator assembly  100  of  FIGS.  9 - 19   . The description of  FIGS.  9 - 19    is applicable to the dispenser actuator assembly  100  of  FIGS.  35 - 36    regarding structure and operation. Certain differences are discussed herein. In this embodiment, the apertures  144  extend completely through the actuator arms  132   a,   132   b.  Thus, the apertures  144  extend through the first segments  152   a,   152   b  of the protrusions  150   a,   150   b.  In addition, the ridges  148   a,   148   b  of the finger pads  146   a,   146   b  have different segments. For example, one segment of the ridges  148   a,   148   b  on the intermediate segment  138   a,   138   b  of the actuator arms  132   a,   132   b  are generally transverse to other ridges  148   a,   148   b  on the actuator arms  132   a,   132   b.  In addition, the depending protrusions  150   a,   150   b  also have a different configuration. The second segment  154   a,   154   b  of the protrusion  150  tapers towards a minimal dimension generally at an intermediate portion on an underside of the actuator arm  132   a,   132   b.  An additional boss  164  ( FIG.  36   ) is also included at an intermediate portion of the second segment  152   a,   152   b  of the depending protrusion  150   a,   150   b.  The description of  FIGS.  9 - 19    is applicable to the dispenser actuator assembly  100  of  FIGS.  35 - 36    regarding structure and operation. 
       FIGS.  37 - 38    disclose another alternative embodiment of the dispenser actuator assembly  100  according to an exemplary embodiment of the invention. The structure of the dispenser actuator assembly  100  of  FIGS.  37 - 38    is similar to the structure of the dispenser actuator assembly  100  of  FIGS.  9 - 19   . Similar to the embodiment of  FIGS.  35 - 36   , the apertures  144  extend completely through the actuator arms  132   a,   132   b.  The depending protrusions  150   a,   150   b  are rigid and have a similar configuration to the previous embodiments and also have a thinner dimension at the second segments  154   a,   154   b.  The description of  FIGS.  9 - 19    is applicable to the dispenser actuator assembly  100  of  FIGS.  37 - 38    regarding structure and operation. 
       FIGS.  39 - 40    show a plurality of dispenser actuator assemblies  100 . It is shown that the length of the first and second actuator arms  132   a,   132   b  can vary such as for adjusting the moment arms and desired forces required to deflect the arms  132   a,   132   b.  Also, the actuator arms  132   a,   132   b  could have a change in angle formed at an intermediate portion of the arms  132   a,   132   b.  It is understood that such angle could vary as desired. Other structures of the dispenser actuator assembly  100  in  FIGS.  39 - 40    are similar to the dispenser actuator assembly  100  of  FIGS.  9 - 19   . The description of  FIGS.  9 - 19    is applicable to the dispenser actuator assembly  100  of  FIGS.  39 - 40    regarding structure and operation. 
     Prior to the invention, a user typically must squeeze, via finger pressure, the outer container  14  of the glass ampoule assembly  10  to crush the glass ampoule  12 . The squeezing thumb/fingers provides a force to deform the outer container  14  and crush the glass ampoule  12 . The required finger pressure could be considered significant for certain users having limited strength in their respective digits. The dispenser actuator assembly  100  provides mechanical advantage from the actuator arms  132   a,   132   b  wherein the required finger pressure can be reduced.  FIG.  41    shows graphically, the reduction in finger pressure required to crush the glass ampoule. The upper line represents the finger pressure required to crush the glass ampoule assembly  10  when a user directly squeezes, via finger pressure, the outer container  14  of the glass ampoule assembly  10 . The required pressure is typically approximately 15-20 psi. The lower line represents the finger pressure required to crush the glass ampoule assembly  10  when the dispenser actuator assembly  100  is used. As can be seen, the finger pressure required is typically less than 5 psi and could be approximately 3-4 psi. A significant reduction in required psi is achieved with the dispenser actuator assembly  100 . A lower, more constant and predictable breakage force is also achieved. It is understood that the dispenser actuator assembly  100  could include alternative features to provide further reduction is required psi as desired. It is understood that the angle that the actuator arms  132   a,   132   b  extend from the base member  102  or flex plate  180  can vary and set at a greater angle that would allow more force to be generated. This can lead to a more difficult grip for certain users and, therefore, a sufficient angle is determined to provide the necessary rupturing force with an ergonomically-friendly grip of a user. 
     It is understood that the dispenser actuator assembly  100  and the glass ampoule assembly  10  may be distributed or sold as a kit, e.g., together as a single unit package.  FIG.  42    shows a representative package assembly  220 , which may be a blister package  220 . The blister package  220  containing the dispenser  10  and actuator assembly  100  may be referred to as a dispenser and actuator assembly package assembly. The dispenser actuator assembly  100  is mounted on the glass ampoule assembly  10  generally proximate a central intermediate segment of the outer container  14  of the glass ampoule assembly  10  to form a tandem unit. The package assembly  200  is provided having a bottom member  222  or blister layer  222 . The blister layer  222  has a blister recess  224  dimensioned to receive the tandem unit. The recess  224  has a first recess section  226  and a second recess section  228 . The first recess section  226  has a greater longitudinal dimension than a lateral dimension to receive and accommodate the glass ampoule assembly  10 . The second recess section  228  is generally rectangular and intersects the first recess section  226  at generally a central portion of the first recess section  226 . The second recess section  228  defines an outer wall  229 . The second recess section  228  is generally dimensioned to receive the dispenser actuator assembly  100  mounted on the glass ampoule assembly  10 . When the tandem unit is placed in the recess  224 , package spaces PS are defined between the actuator arms  132   a,   132   b  and the glass ampoule assembly  10 . The bottom member  222  can be formed from materials that resist inadvertent forces being placed onto the actuator arms of the dispenser actuator assembly inside the package. The blister layer  222  can be made from a variety of different materials. In one exemplary embodiment, the blister layer  222  is made of a thermoplastic material, such as polyvinyl chloride or polyolefin. Still other materials are possible and the blister layer  222  can also be laminated with other layers such as a tear resistant layer. 
     As discussed, the package assembly  220  may be considered a blister package wherein a cover member  230  or film member  230  is adhered over the blister layer  222  to seal the tandem unit in the package assembly  200  until ready to be used. The cover member  230  can also be made from a variety of materials including a paper material, a thermoplastic film layer or a foil layer or still other materials. The foil member could be an aluminum foil. The cover member  230  could also be formed from a laminate material of a paper and a metal foil layer. The foil layer could also be coated with a film of a thermoplastic material such as polyethylene, polystyrene or the like. The cover member  230  is secured to the blister layer  222  by sealing through the application of heat and pressure. Other sealing techniques between the cover member  230  and the blister layer  222  can also be utilized. In one exemplary embodiment, the cover member  230  is releasably secured or releasably sealed to the blister layer  222 . The cover member  230  may define a pull tab for a user to pull the cover member  230  from the blister layer  222 . In other exemplary embodiments, the cover member  230  can be punctured or torn to gain access to the dispenser and actuator assembly tandem unit. The tandem unit in the package assembly  220  can then be further packaged, boxed, shipped or otherwise transported in preparation for use. 
       FIGS.  43 A-C  show additional features associated with the package assembly  220 .  FIG.  43 A  shows the package assembly  220  containing the tandem unit of the dispenser actuator assembly  100  mounted on the glass ampoule assembly  10 . The tandem unit is positioned in the blister recess  224 . As further shown in  FIG.  43 A , wedge members  232 , or first and second blocking members  232 , can be utilized between the glass ampoule assembly  10  and the actuator arms  132   a,   132   b  of the dispenser actuator assembly  100 . The blocking member  232 , or wedge member  232 , generally has a right-triangle-type shape having an angled surface  234  and a primary linear surface  236 , as well as a secondary linear surface  238 . A right angle is defined between the linear surfaces  236 , 238 . In this exemplary embodiment, two wedge members  232  are utilized, e.g. a first blocking member  232  and a second blocking member  232 . As further shown in  FIG.  43 A , a first blocking member  232  is positioned in the package space PS or recess space PS in the second recess section  228  generally between the first actuator arm  132   a  and the second container  14  of the glass ampoule assembly  10 . In particular, the first angled surface  234  of the first blocking member  232  is positioned in confronting relation to the second segment  154   a  of the depending protrusion  150   a.  The second segment  154   a  of the first depending protrusion  150  defines an inclined surface as shown in  FIG.  43 A . In an exemplary embodiment, the respective surfaces of the angled surface  234  of the blocking member  232  and depending protrusion  150  engage one another. It is understood that a small gap could be present if desired. The primary linear surface  236  engages the outer surface of the second container  14  of the glass ampoule assembly  10 , e.g. the straight cylindrical surface of the second container  14 . The secondary linear surface  238  engages a rear wall portion of the second recess section  228 . Thus, the first blocking member  232  is confined or wedged between the first actuator arm  132   a  and the second container  14  of the glass ampoule assembly  10 . 
     Similarly, a second blocking member  232  is positioned in the package space PS or recess space PS in the second recess section  228  generally between the second actuator arm  132   b  and the second container  14  of the glass ampoule assembly  10  (e.g., generally opposed to the first blocking member  232 ). In particular, the second angled surface  234  of the second blocking member  232  is positioned in confronting relation to the second segment  154   b  of the depending protrusion  150   b,  that defines a second inclined surface of the second actuator arm  132   b.  In an exemplary embodiment, the respective surfaces of the second angled surface  234  and depending protrusion  150  engage one another. It is understood that a small gap could be present if desired. The primary linear surface  236  of the second blocking member  232  engages the outer surface of the second container  14  of the glass ampoule assembly  10 , e.g. the straight cylindrical surface of the second container  14 . The secondary linear surface  238  engages a rear wall portion of the second recess section  228 . Thus, the second wedge member  232  is confined or wedged between the second actuator arm  132   b  and the second container  14  of the glass ampoule assembly  10 . As further shown in  FIG.  43 A , the respective distal ends  136   a,   136   b  of the first and second actuator arms  132   a,   132   b  confront and engage outer walls  229  of the second recess section  228  of the blister recess  224 . 
     As can be appreciated from  FIG.  43 A , in this configuration, the first blocking member  232  and the second blocking member  232  prevent movement of the actuator arms  132   a,   132   b  towards one another to prevent premature crushing of the glass ampoule  12  of the glass ampoule assembly  10 . Even if a small gap is provided between the actuator arms  132   a,   132   b  and the angled surfaces  234  of the blocking members, the gap is controlled such that the actuator arms  132   a,   132   b  cannot move enough to crush the glass ampoule  12 . Thus, in this configuration, the package assembly  220  can be further packaged, shipped and transported wherein any jostling of the package will not allow for inadvertent or premature actuation of the glass ampoule assembly  10 . 
       FIG.  43 B  shows an alternative embodiment of the package assembly  220 . In this embodiment, the first blocking member  232  and the second blocking member  232  are integrally formed in the blister layer  222  of the package assembly  220 . In an exemplary embodiment, the blocking members  232  can be pressed to be integrally formed such as in the shape of the blocking member  232  shown in  FIG.  43 A . Other processes can be used to form the integral blocking members  232  such as blow molding or the like. Thus, the integral blocking member  232  formed in the blister layer  222  can have the angled surface  234 , primary linear surface  236  and the second linear surface  238 . The integral blocking members  232  are positioned between the actuator arms  132   a,   132   b  and the glass ampoule assembly  10  as described above. As can be appreciated from  FIG.  43 B , in this configuration, the blocking members  232  prevent movement of the actuator arms  132   a,   132   b  towards one another to prevent premature crushing of the glass ampoule  12  of the glass ampoule assembly  10 . Thus, in this configuration, the package assembly  220  can be further packaged, shipped and transported wherein any jostling of the package will not allow for inadvertent or premature actuator of the glass ampoule assembly  10 . It is appreciated that the integral blocking members  232  in  FIG.  43 B  would look the same as in  FIG.  43 A . 
       FIG.  43 C  shows a further alternative embodiment of the package assembly  200 . The blister layer  222  further has integral blocking members  232  formed therein. In this configuration, the blocking members  232  are generally round or circular members, e.g. having a circular cross-section. Similar to the other embodiments, the blocking members  232  are formed and dimensioned to be positioned between the actuator arms  132   a,   132   b  and the second container  14  of the glass ampoule assembly  10 . As can be appreciated from  FIG.  43 C , in this configuration, the blocking members  232  prevent movement of the actuator arms  132   a,   132   b  towards one another to prevent premature crushing of the glass ampoule  12  of the glass ampoule assembly  10 . Thus, in this configuration, the package assembly  220  can be further packaged, shipped and transported wherein any jostling of the package will not allow for inadvertent or premature actuator of the glass ampoule assembly  10 . 
     The kit described above may include the dispenser  10 , the dispenser actuator assembly  100  and the package assembly  220  including any desired blocking members  232 . It is understood that the kit could include different combinations of such elements or additional elements. For example, the kit could contain multiple applicator assemblies  16  to be used for dispensing flowable materials in different applications. The applicator assembly  16  may also be provided having different tips  54  for different applications. 
     As discussed above, the dispenser actuator assembly  100  can be utilized to actuate a glass ampoule assembly such as shown in  FIGS.  1 - 4   . The dispenser actuator assembly  100  can also be used with other types of glass ampoule assemblies such as the assembly  10  shown in  FIGS.  5 - 8   .  FIGS.  44 - 45    show the dispenser actuator assembly  100  mounted on the glass ampoule assembly of  FIGS.  5 - 8   , and in the first neutral position NP. It is understood that the cardboard sleeve  18  is not utilized in this connection where the cardboard sleeve  18  has been previously removed. The glass ampoule assembly  10  is actuated similar as described above and shown in  FIG.  45   . A user engages the first actuator arm  132   a  and the second actuator arm  132   b  and applies a force F wherein the arms  132   a,   132   b  move towards one another from the neutral position NP to the actuating position AP and wherein the second container  14  is deformed and the glass ampoule  12  is crushed. Flowable material M is then dispensed from the glass ampoule assembly  10  as described above. 
     As described above, the dispenser actuator assembly  100  can be used with a dispenser  10  such as a glass ampoule assembly  10 . It is understood that the dispenser actuator assembly  100  can also be used with other types of dispensers  10  that utilize a rupturable feature in order to dispense flowable materials M from the dispenser  10 .  FIG.  46 - 48    show another dispenser  10  in the form of a plastic ampoule assembly  60 . The plastic ampoule assembly has an outer wall  62  and a fracturable membrane  64  defining a chamber  66  for containing a flowable material M. The membrane  64  has a weld seam  68  formed during an injection molding process wherein a first segment of injected molding material abuts a second segment of injected molding material to form the weld seam  68  such as disclosed in U.S. Pat. No. 6,641,319, which patent is expressly incorporated herein. The membrane  64  having the weld seam  68  could also be formed in a conical shape such as disclosed in U.S. Pat. No. 10,392,163, which patent is expressly incorporated herein. It is understood that the plastic ampoule  60  can also utilized an applicator  16  for dispensing the flowable material M.  FIG.  47    discloses the dispenser actuator assembly  100  mounted on the plastic ampoule assembly  60 . The dispenser actuator assembly  100  and actuator arms  132   a,   132   b  are in the first neutral position NP. It is understood the mounting is such that the interface areas  158   a,   158   b  are positioned proximate the fracturable membrane  64 . Similar to the operation described above, after the dispenser actuator assembly  100  is mounted on the plastic ampoule  60 , a user applies a compressive force F to the actuator arms  132   a,   132   b  wherein the protrusions  150   a,   150   b  at the interface areas  158   a,   158   b  engage and deflect the outer wall  62  of the plastic ampoule  60  thereby applying the force proximate the membrane  64  wherein the weld seam  68  is fractured. Thus, the actuator arms  132   a,   132   b  move the from the neutral position NP to the actuating position AP. Upon fracturing of the weld seam  68 , the flowable material M can pass through the membrane  64  and into the applicator  16  to be dispensed from the plastic ampoule  60 . It is understood that the protrusions  150   a,   150   b  are positioned proximate the membrane  64  to apply the force F to the membrane  64  to fracture the weld seam  68 . 
       FIGS.  49 - 52    disclose use of the dispenser actuator assembly  100  in use with another alternative embodiment of a glass ampoule assembly  10 . The structure of the glass ampoule assembly  10  is generally similar in structure to the glass ampoule assembly  100  of  FIGS.  1 - 4   . The glass ampoule assembly  10  in  FIGS.  49 - 52    utilizes multiple glass ampoules  12  in a tandem unit for a two-part flowable material configuration. Thus, the second container  14  contains a rear glass ampoule  12  and a front glass ampoule  12 . The rear glass ampoule  12  contains a first flowable material Ml. The front glass ampoule  12  contains a second flowable material M 2 .

     The dispenser actuator assembly  100  provides several benefits. The actuator assembly provides mechanical advantage for a user to crush, rupture or fracture the dispenser. The actuator arms can vary in length and resiliency to provide a desired mechanical force in rupturing the dispenser. Because the dispenser actuator assembly allows for a user to apply an increased force than from finger pressure alone, the assembly can be used to rupture more robustly designed dispensers. Such dispensers may be designed to crush under an increased force to minimize the chances of inadvertent rupture. In addition, the dispenser actuator assembly is designed to crush the glass ampoule at the optimal location at the interface area proximate the domed-portion of the glass ampoule to enhance the rupturing of the glass ampoule. Furthermore, as the user engages the actuator arms of the assembly rather than directly engaging the outer container of the dispenser, the chances that glass shards from the crushed glass ampoule can injure the fingers or hand of the user is minimized. The dispenser actuator assembly can also be adjustably mounted along a length of the glass ampoule assembly. For example, the dispenser actuator assembly can be slid along a length of the outer container of the glass ampoule assembly to a desired location. This helps in further manipulating flowable material from the glass ampoule assembly. In addition, the dispenser actuator assembly  100  can be removable attached to the dispenser. Once the dispenser is crushed and the flowable material is dispensed from the dispenser, the dispenser actuator assembly can be removed from the dispenser and used to crush multiple other dispensers. It is understood as well that the dispenser actuator assembly  100  could be manufactured as a single-use assembly that is discarded. It is further understood that the assembly  100  can be positionally adjusted on the glass ampoule assembly  10  to manipulate flowable material as desired or break the glass ampoule at a particular location. It is further understood that the flex plate structure provides several benefits as discussed above including flexing across a greater distance on the plate as well as providing for movement of the actuator arms independently of the support of the glass ampoule assembly by the base member.
