However, once frictional engagement occurs between the interior surfaces 21 and the plunger 20 the locking flange 48 , the locking flange 48 will be at least partially biased inwardly towards the outer cylindrical wall 30 ′. This biased, frictional engagement may result in at least minimal embedding, scraping, penetrating, etc. of the outer free periphery 48 ′ into the interior surfaces 21 , as at 21 ′, of the plunger 20 as at least partially represented in FIGS. 6 and 7 .
- the plunger 20 will be maintained into a movement restricting engagement with the locking flange 48 of the locking structure 46 and/or the outer free peripheral end 48 ′.
- the plunger 20 will thereby be prevented from being returned to the operative or ready position as represented in FIGS. 2 and 4 .
- the provision of the locking device 10 and its interactive movement restricting engagement with the interior surfaces 21 of the plunger 20 will thereby render the dispenser assembly 12 , with which the locking device 10 is used, as a “single-use” dispenser, as set forth above.
- the locking device 10 includes the open interior of the body 10 and the direct communication of the open ends 32 and 34 therewith.
- the locking device 10 including the body 30 can be said to be operatively mounted in at least partially surrounding relation to the dispensing portion 16 of the dispenser assembly 12 as clearly represented throughout the Figures.
- the opened distal end 32 of the body 30 allows passage of the activating member 22 of the plunger 20 into activating or operative engagement with the dispensing portion 16 of the dispenser assembly 12 as clearly represented in FIGS. 5 through 7 . Therefore, the open interior of the body 30 of the locking device 10 can be said to be in receiving relation to the plunger 20 or at least the activating portion 22 thereof when the plunger 20 is forced into the dispensed position as clearly represented in FIG.
- the body 30 and the outer cylindrical wall 30 ′ can also be said to be in at least partially surrounding relation with both the dispensing portion 16 as well as the activating portion 22 of the plunger 20 .
Abstract
A locking device structured to maintain an activating plunger of a dispenser assembly in an inoperative position, subsequent to dispensing, so as to facilitate a single-use operation thereof and thereby preclude the potential confusion between a used and an unused single-use dispensing device. The locking device includes a body disposed in receiving relation to the plunger as it moves from an operative position to an inoperative position. A locking structure connected to the body is disposed to frictionally engage the plunger in movement restricting relation during its passage from the operative position to the inoperative position. Such frictional engagement is sufficient to restrict movement of the plunger back into the operative position once the material has been dispensed.
Description
- 1. Field of the Invention
- This invention is directed to a locking device structured for use in combination with a dispenser assembly and including the structural versatility enabling it to be an original part of the dispensing assembly when manufactured and assembled or as an add-on device. In either application, the locking device is structured to assume a movement restricting engagement with an activating plunger of the dispenser assembly thereby assuring that the dispenser assembly will be used and operated as a “single-use” device.
- 2. Description of the Related Art
- Dispenser assemblies structured to dispense medical or therapeutic compositions into the nasal passages of an individual are common and used extensively for the treatment of nasal and sinus conditions. One typical structure for this type of dispenser is known as a “squeeze” bottle, wherein resilient walls of the dispenser structure are manually compressed, resulting in a mixture of air and intended medication being directed from the discharge nozzle thereof. Typically, a dispenser of this type is intended for repeated use, thereby rendering it difficult to control the amount of composition delivered. In addition, there is a tendency, after discharge, to release the resilient walls of the squeeze type dispenser which in turn results in an inadvertent withdrawal of fluids from the nasal passage. Such fluids typically will accumulate on the exterior surface of the nozzle. As a result multiple users of the same dispenser assembly are in danger of infection by coming in contact with or inhaling the bodily fluids accumulated from the last user or previous users.
- In addition the operation and structure of many dispensers do not provide a meaningful control of the dose or amount of therapeutic composition being dispensed. As a result, the dose regimen for each dispenser cannot be controlled and may result in problems, disadvantages and harm to the user.
- Accordingly, single-dose administration devices are sometimes preferred for a variety of reasons including dose precision and prevention of transmission of infection/reduction of risk of contamination. More specifically, depending on the structural and/or operative features of the administration device, it may be obvious that the dose has been dispensed and that it no longer has any medication in it. However, for other designs it may be difficult or indeed impossible to know if the device has been used or not. Such situations may occur if the administration device does not preclude the operative positioning of an activating member such as, but not limited to, the withdrawal of an activating “plunger” or like component. As a result a discharge device may appear to be identical to a device which has not been discharged. Accordingly, in the latter scenario, a person may not recognize the medication dispenser has been used until after they try to use it. In the case of a medicine that is needed for emergency purposes, this could be extremely dangerous. Therefore, a mechanism that ensures a “used” single-use device could not be “reused” and would therefore not be confused with an “unused” single use device.
- Therefore, there is a need in the art relating to dispenser assemblies specifically including, but not limited to, nasal or other dispenser structures intended to deliver a therapeutic or medicinal composition, for an improved dispenser assembly. Such an improved dispenser structure should be operative to overcome problems and disadvantages of the type set forth above. Accordingly one proposed and improved dispenser assembly can be initially structured and/or subsequently modified to operate as a “single-use” dispenser. As such, the operative components of such an improved dispenser assembly would become inoperable at least to the extent of preventing its re-use thereby limiting the quantity of material that may be dispensed therefrom. As should be apparent, single-use dispensers overcome many of the problems of the type set forth above by allowing only a single dose to be dispensed. In addition due to the fact that a dispenser assembly cannot be re-used, the chances of infections being transferred from one individual to another is eliminated or significantly reduced.
- Moreover, a single-use structuring of a dispenser assembly may involve the inclusion of an improved locking device. Further, the structural and operative features of such an improved locking device facilitates its use as an original component of a dispenser assembly as manufactured and assembled (OEM) or alternatively serve as an “add-on” component to a dispenser assembly which has already been designed and manufactured. Structural and operative features of such a proposed and improved locking device would enable the normal operation of other components of the dispenser assembly such as, but not limited to, an activating plunger movable into a dispensed orientation to facilitate the dispensing of a single dose material from the dispenser assembly. However, the proposed and improved locking device would also serve to interact with the plunger assembly or other operative components of the dispenser assembly to prevent a re-use thereof and/or more than one, predetermined doses being dispensed therefrom.
- Finally an improved and proposed locking device of the type needed to overcome the problems and disadvantages as set forth above would be of simple structure and design and would significantly reduce the cost thereof thereby facilitating its use in a single-use dispenser assembly which may thereafter be discarded.
- The present invention is directed to a locking device which is structured to be used in combination with a dispenser assembly, either as part of its original manufactured components (OEM) or as an “add-on” included after the other components of the dispensed assembly have been designed and manufactured. In either application, the locking device of the present invention renders the dispenser assembly a “single-use” device by preventing or at least restricting an activating plunger of the dispenser assembly from being disposed back into an operative or “ready” position from an inoperative or dispensed position, once a single dispensing cycle has occurred.
- Accordingly, the dispenser assembly, as described and represented herein may be considered only representative of other dispenser assemblies having different structural and operative features. As such, the representative dispenser assembly referred to herein includes a housing, a dispensing portion, an activating plunger, and a supply of material and/or composition intended to be dispensed.
- More specifically, the locking device of the present invention comprises a body dimensioned and configured to be disposed on an interior of the housing of the dispensing assembly in an accessible, engaging relation to the plunger, as the plunger moves from the aforementioned operative or “ready” position into the inoperative or “dispensed” position. In at least one preferred embodiment, the body includes an open and/or hollow interior having oppositely disposed open ends. Further, the body includes a substantially cylindrically configured outer wall disposed in surrounding relation to the open interior and at least partially defining the boundaries thereof. The inner or proximal open end of the body includes a head portion extending transversely outward, about the periphery thereof and includes an outer exposed surface. Fixed positioning and secure mounting of the body within the interior of the housing of the dispenser assembly is facilitated through the provision of a connector disposed in securing position between the outer or exposed surface of the head of the body and correspondingly disposed interior surface portions of the housing dispenser. In at least one embodiment a connector may be at least partially formed of an adhesive material thereby serving to adhesively secure the body of the locking device in its intended position.
- In addition, the body includes a locking structure formed thereon. In at least one preferred embodiment the cylindrical outer wall of the body includes a locking flange connected to the exterior outer wall and extending outwardly therefrom preferably, but not necessarily at an upwardly directed angular orientation. The dimension and configuration of the locking flange will be such as to purposefully interfere with passage and movement of the plunger by sliding but frictionally engaging corresponding portions of the activating plunger as it is selectively forced from the operative, ready position into the inoperative, dispensed position. Once disposed in the dispensed or inoperative position, the frictional engagement between the locking flange of the locking structure and corresponding surface portions of the activating plunger will define a movement restricting engagement therebetween. As a result, activating plunger will be prevented from moving back into the operative or ready-to-use position after a single dispensing cycle of the dispenser assembly has occurred. As should be evident, maintaining the activating plunger in the inoperative or dispensed position prevents its re-use.
- Other structural and operative features of the locking device of the present invention may include the locking flange of the locking structure being at least partially flexible, being formed of a relatively flexible material and/or having at least a minimal amount of flexibility due to its interconnection with the outer wall of the body. As such passage of the activating plunger into the dispensed or inoperative position will force corresponding interior surfaces of the activating plunger into a sliding, frictional engagement with the outwardly extending locking flange of the locking structure. When such engagement occurs, the locking flange may be flexed inwardly towards the outer wall of the body to which it is attached.
- As a result the frictional engagement between the locking flange and the corresponding surface of the plunger will be enhanced and maintained in that the flexible characteristics of the locking flange will tend to bias it outwardly into the aforementioned frictional, movement restricting engagement. As a result, the movement of the plunger back into the operative or ready position will be restricted or prevented, thereby making the dispenser assembly a “single-use” device. As set forth above, the locking device demonstrates sufficient structural versatility to be considered an original component of the dispenser assembly as it is manufactured and assembled. In contrast, the locking structure may be an add-on device so as to assure that the dispenser assembly operates as a single use dispenser.
- Moreover, the dispenser assembly itself may be structured to dispense a variety of different materials and/or be specifically customized or structured as to serve as a single purpose dispenser such as nasal dispenser. In such a latter application, the dispensing portion of the dispenser assembly may be at least partially dimensioned or configured to facilitate specified dispensing procedures, such as including a dispensing nozzle. In addition, the locking device of the present invention is operatively structured with both the dispensing portion of the dispenser assembly as well as the plunger so as to not interfere with movement or positioning of the plunger into operative relation with the dispensing portion and supply of material to be dispensed. Therefore, the open interior configuration of the body as well as the oppositely disposed open ends thereof are disposed and dimensioned to facilitate the normal or intended operation of the plunger as it interacts with the dispensing portion of the dispenser assembly when the plunger is forced from the ready or operative position to the dispensed or inoperative position. However, the aforementioned locking structure at least partially defined by the locking flange will prevent return movement of the plunger from the inoperative, dispensed position back into the operative, ready position.
- These and other objects, features and advantages of the present invention will become clearer when the drawings as well as the detailed description are taken into consideration.
- For a fuller understanding of the nature of the present invention, reference should be had to the following detailed description taken in connection with the accompanying drawings in which:

FIG. 6 is an interior sectional view of the embodiment ofFIGS. 1-5 in a non-operative position upon completion of the dispensing of the material from the dispensing assembly. -
FIG. 7 is a detailed view of the indicated portion ofFIG. 6 . - Like reference numerals refer to like parts throughout the several views of the drawings.
- As represented in the accompanying drawings, the present invention is directed to a locking device generally indicated as 10 structured to be used in combination with a dispenser assembly of the type represented in
FIG. 2 and generally represented as 12. It is emphasized that thedispenser assembly 12 is represented in example form only in that structural features of a different dispenser assembly (not shown) may vary from thedispenser assembly 12 and still be operative when used in combination with the lockingdevice 10. - Accordingly the
dispenser assembly 12 includes ahousing 14 and a dispensing portion generally indicated as 16 connected thereto or otherwise associated therewith. The dispensingportion 16 is operatively associated with a material or composition (not shown) intended to be dispensed. Thedispenser assembly 12 also includes adelivery portion 18 which may be in the form of a nozzle or like structure such as, but not limited to, the type intended to deliver medicinal or therapeutic material to nasal passages of an individual. The delivery portion ornozzle 18 may be appropriately shaped for at least minimal insertion into the nostril and/or nasal passages of the individuals, but is not limited to such a use or application. Additional operative features of thedispenser assembly 12 include a plunger generally indicated as 20, which serves to engage and activate the dispensingportion 16 as it moves from an operative or “ready” position ofFIG. 2 into a “dispensed” or inoperative position as represented inFIG. 6 . - Dependent upon the specific cooperative structuring of the various components of the
dispenser assembly 12, the plunger in the embodiment represented inFIG. 2 has an activatingmember 22 disposable into activating and/or operative engagement with a portion of a dispensingassembly 16 so as to cause the dispensing of the intended material from the dispensingportion 16 and delivery portion ornozzle 18. Accordingly, the activating member orportion 22 moves with theplunger 20 as it is forced within the interior of thebody 14, such that the activating member orportion 22 engages the dispensingportion 16 in an intended manner. Therefore and as indicated above, in the operative or ready position ofFIG. 2 the plunger extends outwardly from thebody 14 in a “non-activating” engagement or relation to the dispensingportion 16. In contrast, the activatingmember 22 associated with theplunger 20 moves into activating engagement with the dispensingportion 16 as theplunger 20 progressively passes through the interior of thehousing 14 in the manner represented inFIGS. 5 and 6 . - With primary reference to
FIG. 1 , the lockingdevice 10 includes abody 30 preferably comprising a substantially cylindrical outer wall configuration and an open interior including oppositely disposed open ends 32 and 34. Thebody 30 also includes a head portion generally indicated as 36 comprising a connectingflange 38 having an outer exposedsurface 38′ which is dimensioned and configured to facilitate secure connection or mounting of thelocking device 10 within the interior of thehousing 14 of thedispenser assembly 12. As represented, the connectingflange 38 extends transversely outward from thebody 30 in at least partially surrounding relation to theopen end 34 and/or the periphery thereof. - As further represented in
FIG. 1 , a connector generally indicated as 40 is dimensioned and configured to be at least partially mounted on theouter surface 38′ of the connectingflange 38. When so positioned, the connectingflange 38 serves to interconnect thebody 30 to correspondingly disposed interior portions, as at 42, of thehousing 14. In more specific terms, at least one embodiment of theconnector 40 may include a substantially annular configuration at least partially corresponding to the annular configuration of the connectingflange 38 and outer exposedsurface 38′. Further, theconnector 40 may be at least partially formed from an adhesive material or have adhesive characteristics sufficient to adhesively interconnect the mountingflange 38 and accordingly the remainder of thebody 30 to interior surface portions or othercorresponding portions 42 within thehousing 14. - Therefore, it is emphasized that the locking
device 10 may be operatively mounted and/or connected within the interior of thehousing 14 and as such may be an original component of thedispenser assembly 12 as it is initially manufactured, produced and/or assembled. In contrast, the structural versatility of thelocking device 10 enables it to be added to adispenser assembly 12, of the type represented inFIG. 2 , as an “add-on” component. In either application, the lockingdevice 10 is structured to facilitate the original manufacture or the conversion of adispenser assembly 12 to a “single-use” dispenser. In doing so, many of the disadvantages and problems recognized in the structural and operative features of known devices of this type are overcome. As set forth herein such problems include, but are not limited to, the monitoring or regulating of the individual dose of material being dispensed from thedispenser assembly 12. - Accordingly, the structural and operative features of the
locking device 10 which enables the operation and use of adispenser assembly 12 as a “single-use” dispenser includes the provision of a locking structure generally indicated as 46. More specifically, the lockingstructure 46 preferably comprises a lockingstructure 46 in the form of lockingflange 48. The locking structure and lockingflange 48 is connected exteriorly of thebody 30 to the outercylindrical wall 30′ preferably, but not necessarily, adjacent or contiguous to acorresponding end 32. In addition, the lockingflange 48, due at least in part to the material from which it is formed or alternatively due to its connection to thebody 30, is at least partially flexible and/or demonstrates flexible characteristics. Moreover, the maintenance of theplunger 20 in the non-operative and/or dispensed position renders the dispenser assembly 12 a single-use device. This is accomplished by the lockingflange 48 frictionally engaging and possibly at least minimally penetrating corresponding interior surfaces as at 21′ as clearly represented inFIGS. 6 and 7 . - Therefore, as the
plunger 20 is pushed inwardly into the interior of thehousing 14, the activatingmember 22 will operatively engage the dispensingportion 16 causing the dispensing of the intended material from the delivery portion ornozzle 18, as intended. However, the forced inward travel of theplunger 20 will also result in theinterior surface portions 21 passing into sliding, frictional engagement with the lockingflange 48 defining the lockingstructure 46. Therefore, as represented inFIGS. 6 and 7 , at least the outer free end orperiphery 48′ of the lockingflange 48 will slidingly engage the correspondingly disposedinterior surfaces 21 of theplunger 20 resulting in a frictional engagement therebetween. Further, when such frictional engagement occurs the lockingflange 48 may be forced or “biased” inwardly towards the outercylindrical wall 30′. Due to the flexible characteristics of the lockingflange 48 as well as the material from which it is formed, the lockingflange 48 will be normally biased outwardly into the orientation or position represented inFIG. 2 , when the lockingflange 48 is not engaged by theplunger 20, as at plunger portion orsurface 21. However, once frictional engagement occurs between theinterior surfaces 21 and theplunger 20 the lockingflange 48, the lockingflange 48 will be at least partially biased inwardly towards the outercylindrical wall 30′. This biased, frictional engagement may result in at least minimal embedding, scraping, penetrating, etc. of the outerfree periphery 48′ into the interior surfaces 21, as at 21′, of theplunger 20 as at least partially represented inFIGS. 6 and 7 . - As a result the
plunger 20 will be maintained into a movement restricting engagement with the lockingflange 48 of the lockingstructure 46 and/or the outer freeperipheral end 48′. Theplunger 20 will thereby be prevented from being returned to the operative or ready position as represented inFIGS. 2 and 4 . The provision of thelocking device 10 and its interactive movement restricting engagement with theinterior surfaces 21 of theplunger 20 will thereby render thedispenser assembly 12, with which thelocking device 10 is used, as a “single-use” dispenser, as set forth above. - Further structural features of the
locking device 10 include the open interior of thebody 10 and the direct communication of the open ends 32 and 34 therewith. As a result, the lockingdevice 10, including thebody 30 can be said to be operatively mounted in at least partially surrounding relation to the dispensingportion 16 of thedispenser assembly 12 as clearly represented throughout the Figures. Further the openeddistal end 32 of thebody 30 allows passage of the activatingmember 22 of theplunger 20 into activating or operative engagement with the dispensingportion 16 of thedispenser assembly 12 as clearly represented inFIGS. 5 through 7 . Therefore, the open interior of thebody 30 of thelocking device 10 can be said to be in receiving relation to theplunger 20 or at least the activatingportion 22 thereof when theplunger 20 is forced into the dispensed position as clearly represented inFIG. 6 . When the activatingportion 22 of theplunger 20 is in the aforementioned dispensed position thebody 30 and the outercylindrical wall 30′ can also be said to be in at least partially surrounding relation with both the dispensingportion 16 as well as the activatingportion 22 of theplunger 20. - Since many modifications, variations and changes in detail can be made to the described preferred embodiment of the invention, it is intended that all matters in the foregoing description and shown in the accompanying drawings be interpreted as illustrative and not in a limiting sense. Thus, the scope of the invention should be determined by the appended claims and their legal equivalents.
- Now that the invention has been described,
