BACKGROU D OF THE ΪΝΥΕ ^' ΤϊΌΝ

Applicators consisting of a wooden, or plastic tube having a bud of cotton on one or both ends, arc widel used for numerous purposes, such as the topical application of substances to the hum n body. A demand exists for a product of this kind, which serves not only as an applicator, but also as a container for substances that are to be applied to the human body. To be practical, such a device would have to have a manually frangible portion that can readily be broken, while at the same lime being so constructed so as to prevent inadvertent fracture, An applicator of this nature would be useful for numerous purposes.

Prior dispensing applicators allow an excess amount of fluid to flow too quickly, and the fluid tends to pool on the surface. Depending upon the fluid being dispensed, such pooling can lead to patient discomfort, chemical bums, and even electrical shock if the dispensed fluid comes into contact with electrical leads attached to the patient's body.

Moreover, in prior art dispensing applicators, the dispensed fluid tends to accumulate at the rear-most portion of the absorbent member, which is closest to the fluid source, instead of preferably evenly spreading throughout the absorbent member. As the volume of the dis ensed fluid gradually increases at the rear portion of the absorbent member,, the fluid begins to uncontrollably drip, thus, causing substantial inconvenience to a user.

A need, therefore, exists for a dispensing applicator overcoming the above- identified drawbacks of the known related art, la particular, a further need exists for a hand-held dispensing applicator that .has a simple structure allowing the practitioner to deliver fluid to the surfaces to be treated in a controllable manner. Another need exists fo a dispensing applicator that has an easily aetuatable structure requiring minimal ipplication of manual force, Further, a need exists for a hand-held dispensing ipplieator thai has a structure minimizing uncontrollabl distribution of fluid,

SUMMARY OF THE INVENTION

In light of the foregoing, an embodiment of the present invention provides a land-held dispensing appiicator comprising a source of fluid, a frangible applicator tip ittached to the fluid source, and an absorbent member attached to the frangible spplieaior tip. When the frangible appiicator tip is broken, fluid flows from the source to the absorbent member, whereby the fluid is applied and spread on a surface. Preferably, the fluid is applied and spread on a surface in a controlled amount. Preferably _. , the fluid source is in the shape of a hollow tube container that is integrally formed, as a single piece,, from a relatively rigid synthetic resinous material, .Preferably, the frangible applicator tip comprises a support element permanently connected to the fluid source, a relatively rigid tongue element extending outwardly of the support element at an end of the container, and a frangible region therebetween. Extending through the support element is a fluid conduit that is open at the end attached to the fluid source and sealed by the tongue element at the end attached to the absorbent member. By deflecting the tongue element relative to the support element, with a force of substantially predetermined magnitude, the frangible region between the tongue and support elements will fracture , _: thereby permitting fluid to flow from the fluid source through the conduit, and into the attached absorbent member. Preferably, the tongue element comprises ribs for reinforcing the tongue element, to resist unintentional breaking of the frangible region. More preferably, the applicator tip comprises a semipermeable or non-permeable cover disposed around the frangible region to control ike speed and direction of th dispersio of the fluid in the absorbent member,

In another embodiment, the dispensing applicator comprises a mounting body which has a stem piece extending from a mounting body fo part, and a lower body part which carries at an underside of the latter, an absorbent applicator. An elongated fluid container having a first end that is attachable at a second opposite end thereof, and with a snap fit, in the stem piece. Optionally, threading of the first end of the fluid container may be used to secure to the stem piece. The container includes a frangible region remote from said .first end, and a rigid tongue element extends longitudinally from, the frangible region, a tip end of the tongue element defining the container's opposite second end.

A fracture anvil is preferably disposed in the stem piece. To fracture the container frangible region in order to release fluid therefrom and into the absorbent applicator, a relative movement: between the container, i.e., the tongue element thereof, and th fracture- anvil is effected. This is done with the tongue element in contact with she fracture anvil, The contact and relative movement produce the rupture of the frangible region, and, more specifically, at the joinder location of the tongue element and frangible region.

In one form, the fracture anvil is a cylindrical body having a cruciform passage extending therethrough ami which receives the flat blade-like tongue element. In a second form, the fracture anvil is a cylindrical body having a partial or one-half cruciform- passage extending therethrough and which receives the flat blade-like tongue element. By effecting a relative rotation betwee the fracture anvil and the container, the fracture of the frangible region results. Optionally, the cruciform passage may extend completely through the fracture anvil, or may only extend partially through the fracture anvil ,

In another form, the fracture anvil is a cylindrical body having a partial cruciform, partial semi-circular passage (e.g., see Figure 42A> extending therethrough and which receives the flat blade-like tongue element. By effecting a relative rotation between the fracture anvil and the container, the partial fracture of the frangible region results. Optionally, the partial cruciform., partial semi-circular passage may extend completely through the fracture anvil, or may only extend partially through the fracture anvil.

In still another form, the fracture anvil is a truncated cylinder received in the stem piece. B urging the container axiaily into the stem piece: and against an inclined end face of the fracture anvil, the tongue element is deflected laterally from its normal disposition to cause the rupture at the joinder location thereof with the remainder frangible- region. With the joinder structure ruptured, the fluid contents release from the container. Flow gutters or channels are defined in the fracture, anvil to insure: free contents flow- from the container past or through the fracture anvil to the absorbent applicator. The arrangement of the tongue element and its structure is designed such as to- allow retention of at least one ribbon residue material connecting the tongue element to the frangible region precluding passing of the tongue element into a contents flow channel wherein it could impede or block flow to the absorbent applicator.

A further feature provides a snap fit cap fitted on an opposite contents filling end of the container opposite the tongue member end, and provided with a seal that excludes any possible and contaminating air presence in the contents at the container end. Optionally, the cap may be screwed on or permanently affixed with glue o some other adhesive. The above and other aspects, features and advantages of the present invention nil become apparent from the following description, read in conjunction with the aicompanying drawings, in which like reference .numerals designate: the same elements.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

As required, a detailed illustrative embodiment of the present invention is disclosed herein. However, techniques, systems, compositions and operating structures in accordance with the present invention may be embodied in a wide variety of sizes, shapes, forms and modes, some of which may be quite different from those in the disclosed, embodiment. Consequently, the specific structural, and functional, details disclosed herein, are merely representative, yet in that regard, they are deemed to afford the best embodiment for purposes of disclosure and to provide a basis for the claims herein which define the scope of the present, invention. Reference will now be made In detail to several embodiments of the invention tiat are illustrated in the accompanying drawings. Wherever possible, same or similar reference numerals are used in the drawings and the description to refer to the same or like parts or steps. The drawings are in simplified form and are not to precise scale, Far purposes of convenience and clarity only, directional terms, such as top, bottom, up, down, over, above, and. below may be used with respect t the drawings. These and similar directional terms should not be construed to limit the scope of the invention in aay manner. The words "connect," "couple," and similar terms with their inflectional .morphemes do not necessarily denote direct and immediate connections, but also include connections through mediate elements or devices.

Referri g now to the drawings, Figs, 1 and 2 in particular, illustrate a dispensing applicator according to the present invention generally indicated as reference numeral 1 , Dispensing applicator 1 comprises an absorbent, applicator member 8, a fluid source 1.6, and an applicator tip 15. Absorbent member 8 ma be of any suitable shape, such as cubic, cylindrical, conical, or wedge- like, and may comprise any suitable absorbent material, such as cotton or sponge, Fluid source 10, or handle, may have any suitable shape. As shown in Fig, 1 , fluid source 10 is preferably a hollow, generally cylindrical body. The end of fluid source body located adjacent to absorbent member 8 Is preferably sealed thereto at a joint or seam 30, such as by heat sealing, to enclose the fluid substance contained within fluid source body 10. Applicator tip 15 comprises an attachment member 1 7 and tongue member 1 8 joined thereto by a tapered frangible region or juncture 1 .

Tongue member 1 8 is preferably a fiat and broad shape that extends a distance into absorbent member 8, such that tongue member 18 is longer than it is wide (see Figs, 4A to 4D). It should be noted that the attachment member 1 ? is relatively thick adjacent the fluid source body 10, and tapers toward frangible juncture .19. Absorbent member 8 s preferably connected to attachment member 17 and/or fluid source body 10,

The manner of utilising dispensing applicator 1 will be self-evident, and simply involves holding the dispensing applicator 1 with the absorbent application member 8 against .an application surface. Dispensing applicator 1 is held such that tongue member 18 is at an acute angle (i.e., substantially parallel) to the application surface. Sufficient, downward pressure of tongue member 18 against the application .surface will deflect tongue member 18 from the central axis c (see Figs. 2, 4 A, 5 A) of the fluid source body 10. At a pre-detenni.ned amount of deflection, the frangible juncture 19 will fractu e or break proximate the intersection thereof but will not separate. Fracture of the frangible juncture 19 will desirably be achieved by the application of approximately 0.25 to 5 pound of force of tongue member 18 against the application surface and will cause opening for fluid flow proximate junctures or aperture 12 as will be discussed, more fully below.

Referring still to Fig. 1, a dip mold process may be used to make source body 10, applicator tip 15, or both, The dip molding process begins with preheating of a male mold made from a material having relativel high heat capacity and coefficient of thermal conductivity. This heated mold is then placed in a fluidi ed bed of meltable particulate resinous material for a time needed to provide a coating of a desired thickness. The mold with melted resinous material is then removed from the flnidized bed, heated a second time and cooled. Finally the tube component is stripped from the mold.

As noted above, it is important for the proper functioning of the applicator that the tube be fabricated from a material that is sufficiently rigid to enable manual fracture of the frangible end portion, if the material is too flexible, deflection of the stem will, not produce the desired result. On the other hand, if the material is excessively rigid and brittle, the possibility of an inadvertent fracture will exist, and compression of the bdy portion to promote flow would be precluded due to the likelihood of cracking:, or simply because excess force, is required. A variety of synthetic resinous -.materials may h utilized, the selection of which will be evident to those skilled in the art. The resin mxsi have a sufficiently low melt viscosity to permit coverage of -all mold surfaces, and it must produce a nonporous and pinhole-free structure. The polymer will normally be a thermoplastic, and exemplary materials include polypropylene, high density polyethylene, rigid polyvinyl chloride and nylon.

The tongue member of the applicator tip will preferably be elongated to facilitat attachment thereof to the absorbent member 8. However, it is not essential that the tongue member 1.8 be of any specific shape and, for example, may be rectangular o cylindrical. Regardless of the shape of tongue member 18, it is essential that suitable reinforcing ribs, as described hereinabove, be included to prevent, unintentional braking or separation of frangible portion 19. Moreover, the shape of tongue member 18 will dictate the shape of the orifice formed in applicator tip 15 where the tongue member 18 is fractured for fluid release. Accordingly, the flow rate and overall amount of fluid applied to an application surface by dispensing applicator 1 is a function of several factors,, including the. shape and strength of tongue member 1 8 (and the resulting orifice), the porosity of absorbent member 8, the density of the fluid, and the force employed by the user when breaking frangible portion 1 and pressing absorbent member 8 against the application, surface. Determining the optimal flow rate for a given application, is well within the ability of one skilled in the art and, therefore, will not be elaborated upon herein.

As stated above, the porous member may be made of any suitable maierial(s), most notably open cell, soft, and pliant sponge-like foam, that may be, for example, a po!yurethane composition, The choice of material will depend largely upon the particular application and the characteristics of tongue member I S and the fluid held, in source body 10. In its normal ^' form, source body 10 will be of circular cross-section. However, tther shapes are also believed to. be feasible. The source body 10 may have a square, i angular, or rectangular cross-section, and the shape may indeed be asymmetrical in cross section and of dissimilar shapes at different points along its length, It will he appreciated therefore that, as used .herein the term "diameter" is to be construed in a broad sense, so as to be applicable to non-circular elements corresponding t those shew , and to refer to the maximum cross-sectional dimension of the element Although normally completely hollow, the source body 1 0 may include appropriate reinforcement elements, such as internal support, pillars, to provide adequate overall strength and rigidity, while permitting the source body 10 to have a thinner than would otherwise be possible. Likewise, source body .10 may include a solid portion, for example, to be gripped while breaking frangible portion 19, so that source body 10 will mi be prematurely compressed or squeezed, which might result in too much fluid ffowing. too quickly into absorbent member 8.

As shows in Figs. 3B and 30, breaking frangible juncture 19 will result in the formation of one or .more apertures 12 through which, fluid from source body 1 0 may flow into absorbent member S (not shown, but fluid flow is shown from apertures 1.2), such that tongue portion 1.8 may remain flexibly fixed to frangible juncture member 1 aad is preferably prohibited from separation, in other words, fracture of the region proximate apertures is required, but tongue portion 18 remains flexibly joined, along a binge line and is strengthened by rib members 31 , as will be discussed.

In its .most, preferable form, all portions of the source bod 10 will have a wai l thickness that is substantially uniform at a value of about.0.005 inch to about 0.025 inch (about 0.127 mm to about 0.635 mm), but may become thinner proximate regions 12 to urge ready fracture. The source body 10 is preferably made of polypropylene having a density of 0.897 g/cm ² and a flexural modulus of about 150 Kpsi (about 1035 MPa), as determined by ASTM method 790B. The source body 10 is preferably about 6 inches to tboui 10 inches in overall length,, and about 0.25 to about 1.0 inches in diameter, so as b be convenient to grasp and still contain sufficient fluid for a single application.

The applicator tip 15 is about 1 to 3 inches long, and abou 0,325 inches in Hameter. The frangible juncture .19 will, preferably have a thickness of about 0,0005 hch to about 0.002 inch (about 0.013 mm to about 0.050 .rnm)„ The one or more apertures 12, which axe -produced by the fractur of frangible juncture 19, bat not the separation of tongue member 18, may be of any suitable size, but preferably have a vidth and height that, is substantially correlated to the width and thickness of large ribs 31 , 32 (see Fig, 3).

Referring to Figs. 3 A and 3C, tongue member 18 preferably comprises a plurality of reinforcing ribs 31 , 32. Due to the reinforcing ribs and the resultant rigidity of tangue member 18, there will be reduced flex along the length of tongue IS, and an applied force on tongue member 18 will be effectively entirely transferred to and concentrated at frangible juncture 19 proximate apertures 12, The result will be the reliable fracturing of frangible juncture 19 proximate apertures 12, which fracturing results in the formation of one or more apertures 12. of suitable size on the same side as ike force application to permit, the fluid within the fluid source body 10 to be discharged therefrom and distributed across a predetermined area of absorbent application member 8 (Fig. 1), As noted above, it will generally be desirable for the material forming fluid source body 1 to be sufficiently thin to permit some compression of fluid source body 10, so as to enable discharge of a liquid therein at a faster rate than would otherwise occur, and/or to promote the flow of the fluid, especially if the fluid is relatively viscous. While in a first use apertures 12 .may only fracture along a portion of the aperture directing fluid flow along one side (the force application side) if force is directed in the opposite direction, apertures 12 will fracture along their remaining region, retaining tongue member 18 only by the flexible hinge between apertures 12 and strengthening ribs 31. Fig, 4A illustrates a first arrangement of ribs for a tongue 18a, As how., tongue 18a is rectilinear in. shape with a bottom edge 40a, a top edge 41 , and side edges 42a, 43a.

Figs. 5A and 5B illustrate a second dispensing applicator 100 according to the present invention. Dispensin applicator 100 comprises an applicator head 10S, a source of fluid, which is shown as a hollow, generally cylindrical body 1 10, and an applicator tip 1 15, which has an attachment member 117 and. tongue member 1 I S joined thereto by a tapered frangible juncture member 1 19 having fracture sites as noted above at 12 (see Fig. 3C). Fluid source bod 1 10 and. applicator tip 1 IS are respectively identical in form and function to fluid source body 10 and applicator tip 15 described hereinabove in reference to Figures 1 thro gh 4D. In addition, dispensing applicator member 100 is provided with an absorbent swab- member 201 , and an inwardly projecting ridge-shaped member 215 provided within body 1 10. A portion of body 1 10 is adapted to hold and/or support absorbent applicator .member 105. As shown, absorbent applicator member 105 is held and supported on a surface .106. Surface 106 is provided with at least one aperture 107, such that the fluid may flow from the interior of bod 1 10 into absorbent applicator member 105, as discussed in further detail herein below. Furthermore, a portion of body 1 10 is adapted to hold and/or support absorbent, swab member 2.10.

As shown, absorbent swab member 210 is held and supported on a surface 203 that is connected to- body 1 10 by a stock member 204, Absorbent $ a.b member 210 is preferably not in fluid communication w h the interior of body 1 1 . Outer surface 201 of absorbent applicator member 105 is oriented relative to body 200 such that, when absorbent applicator member 105 is substantially parallel to an application surface (i.e., i contact with the application surface), the jenttal axis c of body 1 10 forms an _. angle of about 45° with the: application surface, which angle provides a comfortable grip for the user and facilitates- the flow of fluid through the inierio of od 110 into absorbent application member 105. Similarly, absorbent applicator member 105 ^■ >f absorbent swab member 210 is oriented relative to body 200, such that, when absorbent swab member 21.0 is substantially parallel to an application surface (i.e., in contact with the application surface),, the central axis c of body 200 forms an angle of about 3 ^' 0° with the application surface, ¾'hich angle provides a comfortable grip for the user and allows the user to spread the applied fluid over a relatively large area with relatively less arm movement and/or extension.

The manner of utilizing dispensing applicator 100 involves holding the dispensing applicator 100 with the absorbent application member 105 against an application surface. Downward pressure of applicator 100 against the application surface will displace head. 108 upwardly and force ridge-shaped member 215 into contact with tongue member 1 1.8, Sufficient upward pressure of ridge-shaped member 215 against tongue member 118 will upwardly deflect the tongue member 1 18 from the central axis c of the fluid source bod 110» A a predetermined amount of deflection, the frangible juncture U9 will fracture or break at apertures 12 (see Fig. 3C), but not along the entire hinge region or at strengthening ribs (not shown) preventing unintended separation. Fracture of the frangible . juncture 1 19 will desirably be achieved by the application of approx matel 0,25 to 5 pounds of downward force of applicator 100 against the application surface. Breaking frangible juncture 1 19 will result fluid front Quid source body 1 10 flowing into head 108 via apertures 12 (not shown, but noted in Figs, 3A-3C), Comparable to breaking frangible- region 1 of applicator tip 15, as discussed herein above in reference to Figures 3 A to 3C, breaking frangible region 1 19 pf applicator tip 115 results in the formation of one or more apertures in applicator tip 1 15 through which fluid from source body 1 1 may. flow into head 108 without the- unintended separation of the tip member- 1 15. Thus, in general, applicator tip 15 is .comparable in .form and structure to applicator ti 1 15.

Absorbent swab member 210 may be- employed for a variety of purposes. Swab 0 may be used to spread fluid over the application surface- after the application neniber 10.5 initially applies the fluid. Using swab 210 in this way would be jarticulariy advantageous if the amoun of fluid that is desired to- cover a relatively large surface area has been inadvertently applied to a relatively small area, which may occur if application member 105 becomes over-saturated with fluid and can no longer effectively regulate the flow rate and amount of fluid being applied. Moreover, swab member 210 may be used t soak up fluid on the application surface, for example, when an excess of fluid has been applied or the fluid has been applied over the wrong area.

As stated above, absorbent swab member 210 Is preferably not in fluid communication with the interio of body 200. However, a possible use tor swab 210 is applying fluid t a second surface area that is separate and apart from, the surface area over which used absorbent application member 105. In the. critical interest of avoiding cross-contamination, it is desirable to use the application- member 1.05 over only a single contiguous surface area that should be relatively limited (e.g., the upper front of the torso, instead of the entire front of the torso). Accordingly, after an initial application, any additional fluid in a given dispensing applicator may go wastefully unutilized. Therefore, in another embodiment of absorbent applicator head 108, there is provided at least one aperture (not shown) in surface 203, such that fluid may flow from the interior of body 200 into absorbent swab member 210.

Head 108 may be detachable from fluid body 1 10. Fluid body 1 10 may contain an amount of fluid ^' that is greater than is necessary for a given application. Accordingly, after an initial application, any additional fluid in a given dispensing applicator may go wastefully unutilized. Therefore, in another embodiment of applicator 100, fluid body 1 10 is removably attached to head 108 so that head 108 may be disposed of separately from fluid body 1 10. If fluid body 1 10 contains residual fluid after an initial application, other absorbent head may be attached, to fluid body Ϊ 10, thereby allowing the residual fluid to be applied to another application surface.

Referring to Fig, 6, as stated above, it is desirous to avoid cross-contamination by using a given absorbent applicator over only a single contiguous, relatively limited, surface area, Yet, using a given absorbent application in such a manner will often result in an amount of .fluid therein being wasted, Accordingly, a dispensing applicator according to the present invention, generally indicated as reference numeral 300, may be provided with a relatively larger, multi-sided absorbent applicator member 308, such that different sides thereof may be used on different, surface areas.

Referring to Fig. 7, there is shown an applicator tip having a semi -permeable or non-permeable cover 400 substantially surrounding frangible juncture. 19. The purpose of cover 400 is to control the speed and direction of the dispersion of fluid in a surrounding absorbent member (not shown).

Preferably, a rearward edge 401 of cover 400 will be attached to applicator tip 15, More preferably, rearward edge 401 will be fully sealed, around applicator tip 1.5 without gaps or boles so that fluid may not. flow rearward under edge 40.1. If cover 400 is semi-permeable adjacent to rearward edge 401, fluid may flow rearward through cover 400 _. , but preferably will not flow rearward under edge 401 given the more preferable ftrii sealed attachment thereof to applicator tip I S. Is contrast, a forward or distal edge 402 of cover 400. is preferably free and unattached t applicator tip 15 so that, fluid may flow forward under cover 400 substantially without being impeded thereby.

Preferably, cover 400 is formed as a seamless,, unitary cylindrical sleeve (e.g., having a circular, square, or rectangular cross-section). Nonetheless, cover 400 may be of any suitable shape and construction. Depending upon its intended function, cover 400 may be semi-permeable or impermeable to fluid. Cover 400 may be made of various materials, including natural and/or synthetic rubbers, thermoplastics (e.g., polyethylene) , eellnlosio materials or similar fibers (i.e., natural polymeric fibers), and metallic materials. Cover 400 may be a contiguous sheet, a mesh, a felt, o another suitable form, with or without reinforcing .fibers and/or seams (i.e., "rip-stop" seams).

Preferably, cover 400 is pliable and flexible so that it does not impede deflection of tongue member 18. In other words, it is preferable thai cover 400 does not hinder die breaking of frangible juncture ί 9.

However, surrounding frangible juncture 19 with a cover 40 having suitable thickness and/or stiffness will provide a level of reinforcement that prevents inadvertent breaking of frangible juncture 19. Accordingly, by employing a suitable thick, and/or stiff cover 400, tongue member 18 may be provided without reinforcing ribs. Thus, employing cover 400 to reinforce frangible juncture 19 will advantageously simplify- production, of application tip 15, since tongue member 18 may be molded as a simple: flat, extension.

Controlling a rate of dispensing fluid is critical because a) over saturation of the absorbent member reduces the collecting capability of this member, and b) back flow of the delivered fluid from the distal end towards the proximal ^' end of the absorbent member interferes with the physician's work. Accordingly, Fig. 8 illustrates a further embodiment of the invention directed to a dispensing applicator 350 which is configured ^' to prevent fluid from uncontrollably entering a attachment member 354 that is coupled to tip 15. At least one, but preferably a multiplicity of capillary vessels 352 is provided withi the attachment member. Being in fluid communication with a source body 360, vessels 352, by virtue of their cross-section, meter an amount of fluid penetrating into the absorbent member (not shown). Thus, a combination of the openings, which are formed as a result of breaking frangible region 19 and vessels 352, effectively limits oversaturation of the absorbent member.

Still another embodiment of a dispensing applicator 450 is illustrated in Fig. 9, As shown, applicator 450 does not have a frangible structure or region. Instead, an attachment member 452 is provided with at least one or more capillary vessels 454 oontfollably traversed by fluid from fluid source 464. Vessels 454 proj ct into an applicator tip 465 while penetrating a proximal end of an absorbent member 456. The cross-section of the vessels is selected to provide a metered, delivery of fluid.

However, absorbent member 456 can still accumulate an excessive amount of fluid, which will eventually result in a baekflow towards the proximal end of the absorbent member and subsequent voluntary evacuation of fluid via this end. To limit or minimize such a possibility, applicator 450 has flow limiting component or cover 458. Formed, within absorbent member 456 and. preferably, sealed to the proximal end thereof, cover 458 is able t collect fluid flowing towards the proximal end of absorbent member 4.56 and, thus, prevents uncontrollable evacuation of accumulated fluid.

As illustrated, cover 458 is provided with a body having a pair of concave sides 460 whose free or distal ends are spaced from one another at a distance that defines an open exit/entrance fo fluid. The bottom portions 464 of cover 458 extend complementary to converging flanks 466 of attachment member 452. Stability of an applicator tip 465 is added by providing the distal end of attachment member 452 with a rib 470. Note that cover 458 does not completely prevent backflo of fluid leaving a space within the absorbent member which is sufficient to amply, bat not excessively, wet the surfaces of this member.

A farther embodiment of dispensing applicator 479 is illustrated in Figs. 1 OA and l OB. Applicator 479 has a frangible region 1 structured substantially similar to the like configured regions which are discussed in detail above. To prevent uncontrollable evacuation of fluid via a proximal end 474 of an absorbent member 476, applicator 479 has a cover 472 functioning similarly to cover 458 of Figure 9. However, cover 472 is configured with a pair of rectilinear flanks 478 and a bottom portion 480 that extends parallel to a flat distal end of attachment member 17. Cover 472 may also be cone-like.

The applicator 479 is formed by inserting cover 472 into and .sealing it to the interior of absorbent member 476. The bottom portion 480 lies preferably flush with the proximal end of the absorbent member and is sealingly attached to frangible region 19.

Embodiments of a dispensing applicator 490 il lustrated in Figs. 1 1 A and 1 IB are conceptually close, to the embodiment illustrated in Figs. 5A and 5B and include a applicator head 492 which is formed with an absorbent member 494 and a swab member 496. The absorbent and swab members have a center axes A-A and B-B, respectively, which intersect one another forming an angle of about 80-1.00' ^'' .

The difference between the embodiment of Figs. 5 A and SB and the one in Figs. 1 1 A and 1 1 B includes utilization of one or more capillary vessels 498 provided instead of the frangible region. While, swab member 496 of Fig, 1 1 A is prevented from .fluid communication with an interior of a fluid source body, swab member 496 of Fig. l l B is traversed by a capillary tube 499 and has an inner surface 497 in fluid communication with the Interior via an opening 495, for the reasons explained above in reference to Figs, 5 A and 5B„ Another embodiment of the dispenser is depicted in Figs. 12-27, With reference to those Figures, dispensing applicator 60 comprises a mounting block 66 having: a base piece 61, a bottom side skirt part 62 to which, is affixed an absorbent sponge type applicator 63, and a stem piece 64 ups.tand.ing from base piece 61. An absorbent swab 65 is carried at. an adjacent side of the mounting block 66·, for which purpose the mounting block 66 includes a mounting bracket 67 (depicted to advantage in Fig.18) receptive of skirt piece 68 to which swab 65 is affixed.

Stem piece 64 is preferably a tubular component and its interior space is in communication with the interior space 69 of base piece 61 (see Fig. 21 ), the last mentioned spac outletiing to absorbent applicator 63 so tha a flow course in the mounting block 66 has inlet in the stem piece 64 and outlet at applicator 63. An elongated fluid container 70 is attachable to the mounting block, an end of the container being received i stem piece 64.

Referring in more detail to Figs. 12-17, container 70 which is of tubular configuration is capped at a first end as at 71. At a distal opposite end length, an attachment member 72 has a length portion, as at 73, received inside the container; and, the length portio is affixed to the container as, for example, b heat sealing. The length portion has a flange 80 thereon and a continuing length portion 73a constituting a frangible section, this section transitions into a tongue element, 74. The juncture of the tongue element 74 and the continuing length portion 73a defines a weakened joinder location at which the fracture and at least partial separation of the tongue element from the frangible section will occur, enabling otriletting of fluid from container 70.

Figs. 16 and 17 depict one embodiment of a fracture anvil 76, The fracture anvil has a cruciform passage 77 extending therethrough, as well as a number of fluid pass-through passages 78 for enabling .fluid released on fracture to flow toward absorbent applicator 63.

When the second opposite end of the container 70 is inserted into the stem piece 64, the tongue element is aligned such that it will enter and locate in the cross passage part 77a of cruciform passage 77, the fracture anvil having been, inserted in the bore 72 of the stem piece. The second opposite end of the container 70 is snap fit connected to the stem piec 64. The arrangement is such thai with flange 80 received in annular interna! groove or slot 154 in the stem piece (see Fig. 21 ), the tongue element 74 is properly positioned in cross passage part 77a for effecting fracture.

External dimensioning of the annular flange 80 and internal groove 1 54 is such that the containe 70 can be rotated relative to the fracture anvil whil the fracture anvil is held. This approximately ninety degree rotation of the container i s effective to twist the tongue element 74 at the weakened joinder location with length portion 73a, fracturing it and effecting at least partial separation from length portion 73a. With this fracture, fluid releases from the container into the mounting block through course. Figs 21 , 22 and Figs. 23, 24 show, respectively, pre and post-fracture orientations of length portion 73a.

^' .Pig, 25 shows how fluid outlets the container in streams from apertures S3 at the fracture site of tongue element 74 and length portion 73a, the apertures 83 being shown in Fig, 1.5 as well. Fig. 26 shows the pattern of fluid flow to and distributed throughout the absorbent applicator 63, which distribution is promoted by the passages 8.4 formed in the applicator 63,

Fig. 27 illustrates the orientation of the dispenser 60 when, e.g., it is desired to swab a large patient area, spreading out the quantity of fluid applied to the patient with ¾hsorbent swab 65.

Fig. 28 depicts an embodiment of dispensing applicator 60-2, which is identical with the Fig. 13 applicator 60 except wherein fracture anvil 76- 1 is embodied as a truncated cylinder. The anvil 76-1 shown in more detail in Figs, 32 and 35 is provided with a flat inclined top face 132, and with a flat chord face 1.77 a the cylindrical periphery thereof and extending between top face 132 and a bottom face 1 79, With the anvil 76-1 received In stem piece 64 as shown in Figs. 35-37, flat, chord face 177 is disposed spaced from the cylindrical inner surface of the stem piece 64 and therewith defines a flow channel along which fluid contents of container 70 can flow from interior space 99 of the stem piece 64 to the interior space 69 of base piece 61. Referring to Figs. 35-37, explanation of fracturing for fluid flow (but not. separation) of the frangible weakened joint at which the tongue elemen 74 is connected to the frangible length part 73a is now given. The circular inner surface of the stem piece 64 is shouldered or provided with a stop as at 13 to hold the fracture anvil 76-1 (Fig, 32) i stopped position so it cannot move lower in the stem piece passage. When the applicator is to be used, a fluid container 70 will be inserted into the stem piece 64, tongue element 74 first. The ti end of the to gue element 74 will i course of insertion travel strike against the inclined top face 132 of the fracture, anvil 76-1 in consequence of which the tongue clement 64 will be laterally displaced from the full line position thereof in Fig. 35 to the position as shown in Figs 36 and 37. That displacement effects rupture (but not separation) of the tongue element at its joinder location with the frangible region and container fluid, contents are released through orifices 83 (Fig. 15) into the stem piece interior space. It is specifically noted, that in Fig. 31 the separation is shown only tor purposes of visualizing the openings accessed by fracture of the frangible regions, and it. will he recognized that, the inner joining region of tongue membe 74 remains firmly and securely attached to head member 80, and is merely displaced allowing a fluid-flow access, to the openings, noted. Thus, Fig, 31 ts for illustrative purposes only and does not reflect a separation.

Additional fracture anvil embodiments are shown in Figs. 33 and 34. In these embodiments, the truncated cylinder anvils 76-2 and 76-3 unlike fracture anvil 76-1 , retain their outer surface cylindrical envelopes. Like fracture anvil 76-1, these anvils- each have an inclined flat top- face 132 and a flat bottom face 179, To provide flow from the Inclined top face to the flat bottom face side of the fracture anvils, gutter-like flow channels 133 are formed in the cylindrical peripher of each anvil, these flow channels 133 extending from the inclined top face 132 to the flat bottom face 179. Fracture anvil 76-2 has one flow channel or relatively large cross section area, whereas, fracture anvil 76-3 has plural, i, e,, three flow channels each of smaller cross section area but in total about the same as the cross section area o fracture anvil 76-2, The flow channels 133 juxtapose with the inner encircling periphery of the stem piec and provide ample artery volume to insure proper fluid flow to the absorbent applicator 63 An important consideration in the dispensing applicator is (a) complete filling of •eMtainer 70 during .manufacture to ensure maximum supply and (b) avoidance of contamination of the fluid contents in the container 70 both as to at Initial filling of disinfectant and medicaments therein and as to post filling handling and storage until Bjed to use. It will be recognized by those of skill in the art, that achieving (a) will eliminate air pockets prior to use that will impact contamination in (b), in this .regard aid with continuing reference to Figs. 29 and 30, the container 70 of dispensing applicator 60-2 is provided at its first or filling end with a capping assembly 2.40 (as slown) that includes a closure cap 2.4 ! having a central, disc part 243 and an axiaiiy directed peripheral skirt 242 encircling the oute surface of the container 70 at its first end. The first end tip part of container 70 has a radially inwardl directed annular fbnge 244 defining a central opening 245 (See Fig. 30) in the container ti end. A boss 2 projects axial! y from the inner fac of central disc part 243 and with the cap in place on the container first end, the boss 248 ^' will locate a distance through central opening 245 upon assembly. The capping assembly also includes a, e.g., foil material gasket 2.50 constructed from a suitable material which is used to intervene the inner side of the closure cap 241 and the first end face, i.e.. the annular flange 244 outer face of the container 70.

Fig, 30 depicts the manner of container filling. A filling line 252 (show as a tube) i the sterile filling operation environment delivers disinfectant, or medicament fluid as discussed herein of any suitable kind through central opening 245 into the container until there is overflow of fluid at which point the .filling is terminated. Gasket 250 is then set on top of the outer face of flange 244, the gasket being o larger area expanse than flange 244 and makes liquid contact for sealing purposes. Further, gasket 250 is selected from materials which are liquid proof, stretchahle or deformabl.e to a certain degree so. that when closure cap 241 is fitted over the first end of the container sandwiched between the closure cap inner face and the outer face of flange 244, an air tight joint seal of the container is effected without, a bubble, since the gasket material will conform to the sandwiching structure m intimate contact therewith. Fig. 29 illustrates this clearly and employs a formed main tube body 70 having only smaller opening 245. it is also to be noted from Fig. 29 that fluid fills the first end of the container 70 and is in air excluding contact with the gasket, and the apparent fluid gap in Fig, 29 is employed only to show depth of the fluid and no the existence of an unfilled portion of the tube. This arrangement assures absence of any possible contaminants-containing air within the container. It is preferred thai the closure cap 241 on.ee in place be not removable from the container. This can be effected by sonic welding or other attachment means of the closure cap t the container and optionally of the foil closure itself. If it is thought expedient for any reason, the ca can be removably snap fitted to the container. For example, an annular groove in one of the structure inner skirt surface and outer surface of the container, and an annular bead on the other of said surfaces will allow removal the closure cap but only with, deliberately Intended such action.

Referring now additionally to Figs. 38-40, an alternative construction is provided at a dispenser system 500 containing a head member 501 secured to a dispensing fluid container 502 and surrounded by a foam dispersing member 503 constructed in a manner previously discussed. As earlier noted, flow shields and flow control devices may be particularly useful in preventing unintended, fluid release, fluid spill back during application (from buildup within foam dispersing member 503) etc.

Similarly, a flexible ti or tongue member 505 is joined with, reinforcing members 508 (shown in the first figure) joined to fracture member 506 on head member 501 so that the fracture about the stressed areas earlier noted (see for example Fig, 3C at 12, the discussion of Fig. A and the related discussions of flexible fracture upon movement of the tongue member while retaining and preventing separation of the tongue -member) is directionall.y out the only side that fractures - that facing the application surface as seen by flows in Fig. 39, As a consequence, fluid flows 510 from the fracture or opening site ma approach an application surface 51 1 upon actuation. Wlv&i is additionally appreciated here, is thai, dual surfaces of foam member 503 is mbstantially beneficial for the reasons noted above.

A flexible plastic card 525 is flexibly retained and fixed in foam applicator head 503 proximate fracture member 506 as shown. Card 525 is formed of a thin, flexible and fluid resistant (impermeable or semi-permeable) material (like a playing card), and includes preferably a plurality of peripheral protuberances or indentations 526 that engage the foam or sponge bead to prevent lateral or longitudinal shifting relative to the fracture location for reasons, that will be discussed. As will be appreciated, the protuberances 526, spikes, detents or other structures or chemical, means (such a glue about the perimeter) may be employed to minimize or prohibit shifting of card shield 525 during manufacture or use applications.

Card 525 includes a bounded opening o slot 528 that is approximately 0,25 laches to approximately 0.75 inches in height and sufficiently wide to span the full 'width of tongue member 505 and the connection: with fracture member 506 so as to position itself as shown generally in Fig. 39.

As an adaptive embodiment the fluid exiting slot on the inferior side of the sponge extends almost the full width of card 525 for a speedy delivery of fluid while protecting the superior side of the sponge from unintended fluid dispersal or pooling. As noted earlier, during surgical preparation a sterile prep item may not be used again on the same patient followin an initial removal as a consequence, the present embodiment minimizes loss or waste by preserving, a second foam side or superior foam side for second use by the same applicator. As a consequence, as noted in Fig, 39 fluid flow Is to the inferior portion of the sponge and. directly applies to the contact surface and flows between the contact surface 51 1 and the surface of card 525 for distribution without penetrating card 525 to translate to the superior portion of the sponge. This action, retains the superior side of the sponge in a substantially or completely dry condition for later sterile use (which may be achieved by .merely flipping the applicator over to the superior side and proceeding as discussed above and demonstrated in the figures.

Another alternative embodiment of the dispensing applicator in accordance with the present invention is depicted in Figs. 41-44. With reference thereto, Figs. 41.A-C show different views of the alternative embodiment of a mounting block for a fluid dispensing applicator according t the invention which receives an absorbent applicator ¾ a block bottom side. In particular, as shown, the dispensing applicator comprises a isolating block 550 having a base piece 552, a bottom side skirt part to which is affixed an absorbent sponge type applicator (see Fig. 43), and a stem piece 554 upstanding from base piece 552.. An absorbent swab may optionally be carried at an adjacent side of the mounting block 550 (see Figs. 5Α-Β·, 11A-B and 12-13), for which purpose the mounting block 550 includes a counting bracket, (e.g.. similar to that shown in Fig.18) receptive of a skirt piece to which th absorbent swab is affixed.. Optionally-, mounting block 550 ma include projections 558 to- aid in rotating mounting block 550 about the axis of stem piece 554 as indicated by arrow 556 to cause fracture of tongue 505 and. fracture member 506 (see Fig. 40) while tongue 505 (see Fig. 40) is positioned within fracture anvil 560 (see Fig, 41 C).

Stem piece 554 is preferably a tubular component and its interior space is in communication with the interior space of base piece 552 (see Fig. IB), the last mentioned, space ouiletting to absorbent applicator 548 so that flow course in the mounting block 550 has inlet in the stem piece 554 and outlet at applicator 548. An elongated fluid container 574 (see Fig. 43) is attachable to the mounting block 550, an end of the container being received in stem piece 554,

Referring in more detail to Figs. 41A-C and 43-44. container 574 which is of tubular configuration is capped at a first end as at 576. At a distal opposite end length, an attachment, member 568 has a length portion received inside the -container 574, and the length portion being affixed to the container as, for example, by heat sealing or snap fit. The length portion optionally has a flange 572 thereon and a continuing length portion constituting a frangible section, this section transitions into a tongue element 570, The - juncture of the tongue element 570 and the continuing lengt portion defines a weakened, joinder location at whic the fracture and at least partial separation of the tongue element 5?0 from the frangible section will occur, enabling ontletth of fluid from container 574.

Referring now to Fig. 42A, shown is a perspective view of an alternate embodiment of a fracture anvil for being removably inserted in an applicator mounting block part of the applicator head, the fracture anvil having a partial cruciform, partial semi-circular passage for reception of the fluid source containe tongue element, the fracture anvil being employed to effect partial fracture of the frangible region-tongue element joinder on a relative rotatable movement between said container and said fracture anvil. Fig. 42B shows a cross-section view of the fracture anvil taken on the line 42B-42B of Fig. 42A,

Turning to Figs. 42A-B, depicted is yet another embodiment of a fracture anvil 560 for use with, the dispensing applicator according to the invention. The fracture anvil 560 shown has a partial erueifoi¾¾, partial ^' semi-circular passage 562 extending therethrough, as well as a number of -fluid pass-through passages far enablin fluid released on fracture to flow toward absorbent applicator 548.

When the second opposite end of the container 574 is inserted into the stem piece 554. the tongue element 570 is aligned such that- it will enter and locate in the vertical cross passage part of partial cruciform, partial semi -circular passage 562, the fracture anvil 560 having been inserted in the bore of the stem piece 554. The second opposite end of the container 574 is snap fit connected to the stem piece 554. The arrangement is such tha with flange 572 received in annular internal groove in the: stem piece (see e.g., Fig. .21 ), the tongue element 570 is properly positioned in the vertical cross passage part for effecting fracture.

External dimensioning of the annular flange and. internal groove is such that, the container 574 can be rotated relative to the fracture anvil 560 while the fracture anvil 560 is held in position. This approximately forty-five degree rotation of the container 574 is effective to twist pari, of the tongue dement 570 at the weakened joinder loc ti n _s fiaeturing a portion of it and effecting at least partial separation from attachment member 568. With this fracture, fluid releases from the container 574 into the mounting block 550 through course.

Referring next to Fig. 43, shown is an exploded left front side perspective view of still another embodiment of a dispensing applicator accordin to the invention wherein a fluid containing source 574 is reeeivably attachable to an applicator, mounting body stem piece 554 in sna fit connection therewith, initiation of fluid flow is then effectuated with a relative rotative movement, as indicated by arrow 556, between the fluid source container 574 and a fracture anvil (see Fig, 44} in the stem piece 554 of mounting block 550. The first end 576 of container 574 has a central opening. A capping assembly is releasably attached to the opening at end 576. The capping assembly also includes a, e.g., foil material gasket 582 constructed from a suit ble, material which is used to intervene the inner side of the closure cap 584 and the annula flange 578 which has a bore 580 therethrough. Gasket 582 is set on top of the outer face of liange 578, the gasket preferably being of larger area expanse than flange 578 and males liquid contact or sealing purposes, Further, gasket 582 is selected from materials which are liquid proof, stretchafcle or deformahle to a certain degree so that when, closure cap 514 is fitted over the first end of the containe sandwiched between he closure cap inne face and the outer face of flange 578, an air tight joint seal of the container is effected without a bubble, since the gasket material will conform to the sandwiching structure in intimate contact therewith.

As seen in Fig. 44, depicted is a cross-section view taken on the line 44-44 in FIG. 43 showing relative position of the tongue member 563 within the partial cruciform, partial semi-circular passage of the fracture anvil, Additionally, the fracture anvil has a number of fluid pass-through passages 561 for enabling fluid released on fracture to flow toward absorbent applicator 548, Referring next to Fig. 45, shown is an exploded left front side perspective view still another embodiment of a dispensing applicator wherein a fluid containing source 574 is reeeivably attachable to an applicator mounting body 588 in snap fit connection tkrewith, initiation, of fluid flow being effected with a relative rotative movement 556 feiweeri th fluid source container 574 and a fracture anvil 560 (see Fig. 46) in the nountmg. body 588, and further showing a dye packet assembly 591 having top and ottom dlffusers 596 each preferably with a spiral-like pathway 595 leading to openings 5 ^: )2 (for passage of the fluid) and a dye tablet 594.

While the present invention is primarily directed to a dispensing applicator for the application of liquids to the surface of the head, limbs, and/or body for medical purposes (i.e., pre-surgical disinfection), dispensing applicators according to the present invention may be used in a wide variety of purposes and environments. For example, a dispensing applicator according to the present invention can be used for application of !uhricant(s) or adhesive(s). The range of sizes can also vary widely, as long as the several wall thicknesses are controlled appropriately to afford the desired functional, characteristics discussed herein. It should also be appreciated by those of skill in the art that the fluid reservoirs, in selected embodiments, are flexibly bounded and allow an operator to control volumetric application based on the amoun of pressure applied, to the exterior of the reservoir. As a consequence of this design, it should also he recognized by those of skill in the art, that an operator releasing a compressed ©servolrs, .ma partially suction released fluid back into the reservoir and minimize fooling.

In the- claims, means- or s ep-j ln -funetion clauses are intended to cover the structures described or suggested herein as performing the recited function and not only structural equivalents but also- equivalent structures. Thus, for example,, although a mil, a. screw, and a bolt may not be structural equivalents in that a nail, relies on friction between a wooden part and a cylindrical surface, a screw's helical surface positively ©gages the wooden, part, and a bolt's head and nut compress opposite sides of a wooden part, in the environment of fastening wooden parts, a nail, a screw, and a bolt, nay be readily understood fey those skilled in the art as- equivalent .structures.

It will be understood that the present invention may he embodied in other specific forms without departing from the spirit or central characteristics thereof. The present examples and embodiments, therefore, are to be considered in all respects as iiastrative. and not restrictive, and the invention is not to be limited to the details given hirein.
