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.
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.

The present invention discloses a dispenser actuator assembly that can be used in conjunction with a dispenser to activate the dispenser and dispense flowable material from the dispenser. The dispenser actuator assembly may also be referred to as an ampoule actuator assembly or a dispenser holder or ampoule holder. The dispenser can take various forms and in one particular application, the dispenser may take the form of a glass ampoule assembly. The dispenser in the form of the glass ampoule assembly will be described followed by describing the dispenser actuator assembly including the connection of the components and actuating the dispenser.
In the exemplary embodiment of the applicator assembly 16 of
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

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
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.

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'clock, 3 o'clock, 6 o'clock and 9 o'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.
As shown in
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.
As shown in
As shown in
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
As further shown in
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 132a,132b 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.
As can be further appreciated from
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 132a,132b. As the slots 118,120 separate the actuator arms 132a,132b from the base member 102, the actuator arms 132a,132b 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 132a,132b. It is further understood that the actuator arms 132a,132b themselves do not generally bend or flex as the arms 132a,132b are more rigid, but the arms 132a,132b 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.
As further can be appreciated from
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'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'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
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 132a,132b 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 132a,132b 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 150a,150b 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 132a and a second actuator arm 132b. 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 132a,132b 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 132a and the second actuator arm 132b are connected by a central hub member 180 or flex plate 180, or torsion plate 180. In particular, a proximal end 134a of the first actuator arm 132a is connected to a top portion or first end of the flex plate 180, and a proximal end 134b of the second actuator arm 132b 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 132a,132b and, as discussed, the first end, or upper end of the flex plate 180 is connected to the proximal end 134a of the first actuator arm 132a, and an opposite second end, or lower end of the flex plate 180 is connected to the proximal end 134b of the second actuator arm 132b. 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 132a,132b.
As can be further appreciated from
As previously discussed and as shown in
As further shown in
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 132a,132b do not pivot or flex towards one another at a specific point or location. The flex plate 180 flexes as shown in
Finally, the structural features of the flex plate 180 and actuator arms 132a,132b minimize unwanted lateral movement of the actuator arms 132a,132b. The actuator arms 132a,132b 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 132a,132b. Minimizing any lateral movement of the actuator arms 132a,132b is desirable as it can affect the proper crush of the glass ampoule 12 as the protrusion 150a,150b may slip to the side of the glass ampoule 12 preventing crushing. As shown in
As discussed, in an exemplary embodiment, the dispenser actuator assembly 100 is formed as a single unit in an injection molding process.
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.
It is understood that the dispenser actuator assembly 100 is formed in the mold cavity including the first actuator arm 132a and the second actuator arm 132b. As shown in
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.
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 132a,132b wherein the required finger pressure can be reduced.
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.
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.
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 132b 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 154b of the depending protrusion 150b, that defines a second inclined surface of the second actuator arm 132b. 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 132b and the second container 14 of the glass ampoule assembly 10. As further shown in
As can be appreciated from
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
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.
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.
It is understood that any reference to an element using designations such as “first” or “second” or the like does not limit the quantity or order of those elements, unless such limitation is explicitly stated. These designations are used to distinguish between elements or other references to an element. Accordingly, a reference to a first element or a second element does not mean that only two elements may be employed or that the first element must precede the second element in some manner. In addition, a set of elements may comprise one or more elements. In addition, references to “top” or “bottom” or “front” or “rear” are used to reference relative positions of elements and should be construed as a limiting positional requirement.
It is further understood that the present description includes several different embodiments with different features depending on the embodiment being described.
