Description
BACKGROUND AND SU~ RY OF TEIE INVENTION
ICnown in the prior art is a package for a flowable product, namely United States Patent No~ 3,986,640, granted October 19, 1976 to Sanford Redmond. This patent teaches a lpackage for a flowable product wherein thê package includes a relatively stiff, but flexible material and a flexible material between which the flowable product to be packaged is contained and around which flowable product the materials are affixed to each other~ The relatively stiff, but flexible material is cut 'I through or partially through in an interrupted pattern and, when ;cut through, at least one side of the relatively stiff, but flexible material, at least in the area of the cut pattern, being ! covered with a sealant, which sealant preferably is a foil, the package, when bentl opening up along the cut patt.ern to dispense the flowable product from the package. The patent also discloses and teaches the flexible material which is used Eor making such a ~I package.
,~l One of the disadvantages of this package is the uncontrollable rate at which the flowable material is squeezed and discharged out of the package~ Due to its form of construction, ` there is no control to the flow from the package, and that it does lnot teach any specific type of packages, such as applicator packages for specific needs in the medical profession. Also, the package of ~.S.P. No. 3,986,640 does not teach the utilization of a multi-cavity reservoir for storage of the flowable product.
With such a multi-cavity applicator package, one can achieve a 'controllable flow of the product from the package during use.
Accordingly, although the prior art package noted herein functions ' in dispensing a flowable product from the package, it lacks the ,1 - 2 ,1 teaching of specific applicator packages which can be used in diverse app].ications. Thus, the packages of the present lnventi.on overcome the problems heretofore encountered with this prior art package and overcomes the disadvantages, and provides a number of applicator packages which have specific applications, particularly in the medical and veterinarian fields. other packages for use in still other fields are also disclosed in the instant application.
.Accordingly, one of the primary objects of the present invention is to provide an applicator package having distal ends comprising a foam applicator pad and having a backing member adjacent thereto: the backing member being formed of a relatively rigid, flat and stiff plastic sheet material having a vapor and gas barrier coating and a laminated deformable plastic coated foil material having at least one reservoir containing a flowable product, such as a liquid, being sealed to the flat and stiff sheet material for containing the contents of the reservoir therebetween; the flat and stiff sheet material having a centrally disposed linear weakened portion in the surface of the flat and stiff sheet material and the weakened portion being transversely disposed of the flat and stiff sheet material with the foam applicator pad secured to the outer surface of the flat and stiff sheet material and centrally disposed over the weakened portion;
the weakened portion rupturing upon forcing the distal ends of the applicator package towards each other and about the weakened portion, so as to compress the reservoir of the deformable plastic coated foil material hy crushing opposite sides of the reservoir against each other such that substantially all of the flowable product in the reservoir can be controllably released into the applicator pad for wiping applications upon pressure completely deforming and mg/J~ - 3 -1 .1Lt;~
collapsing the plastic coated foi.l material; and the foam applicator pad is a foam block having opposite slits partially throuyh the foam block so that when the distal ends are squee~ed together, the foam block assumes an inverted T-shape with a large wiping contact surface area.
The foregoing object and other objects of the present invention will become apparent upon reading the following specification and referring to the accompanying drawings, which form a material part of this disclosure.
The invention accordingly consists in the features of construction, combination of elements, and arrangements of parts, which will be exemplified in the preferred constructions hereinafter described, and of which the scope will be indicated by the claims.

BACKGROUND OF THE INVENTION
This invention generally relates to swab articles, such as swab packages, swab sticks or applicators, scrub brushes with a swabbing or wiping surface, and to other similar type packages adapted for use as bandaids, inhalants and the like, such as skin preping or pre-operative scrubs having cleansing agents, surgica]. scrubs, skin preps for cardiac electrodes and tincture or dye applicators, skin patch testing and through-the-skin dispensing of hormones or medic-aments including time release formulations (such as insulin time release compounds). The swab packages of the invention are basically of the rupturable type embodying a receptacle for fluids, such as ointments, powders, germicides, liquids, gels, pastes, etc. Also, the swab packages include an applicator pad or surface or other like structure, and may be, if desired, suitably packaged with an overwrap to provide sterility.
As best shown in figures 1-4, there is shown a swab package 10 embodying a receptacle or reservoir 12 and an externally mounted applicator 14, such as a gauze pad, plastic foam pad or synthetic cotton or fabric pad. The plastic foam material may comprise a urethane foam material or a natural latex foam. The construction of the receptacle or reservoir 12 is basically of the type disclosed in U.S.P. No. 3,986,640 as noted hereinbefore.
jrc:~ -Thus, for example, wi-th the present invention, the receptacle 12 may compriseon one side thereof a thin, relatively stiff laminate type of plastic sheet material 16, such as an extruded polystyrene, acrilonitride or copolymer with poly-styrene with or without special coatings, such as vapor or gas barriers or heat sealants or bonding coats. The material may be, if desired, initially treated by stretching so as to orient the structure for providing additional strength in one direction only, whereby the material is capable of splitting easily in a direction orthogonal thereto, provided a score line or other weakened area 18 is made a part of the receptacle 12. Such a score or cut line or weakened area 18 is provided on the side or surface 20 to which the applicator 14 is mounted or otherwise secured to the receptacle 12, by means such as adhesives, heat sealing, ultrasonic or electronic impulse bonding or other like securing means. Subsequent to the stretch-ing of the base material, the material is then further provided with any desired laminate coating, such as spraying, or adhering another sheet of material directly on the base material.
The periphery 20 of the receptacle 12 is provided with a marginal seal such as a heat seal, to retain the fluid in said receptacle 12 from escaping therefrom until the receptacle 12 is fractured or ruptured, as will be further described herein in greater detail.
In figures 3-4, the package of figures 1 and 2 is shown initially partially opened b~ bending or folding opposite ends of the package 10, thereby weakening the pre-weakened area or zone 18 so as to finally rupture same. The fluid 22 is thus released to flow directly into the applicator 14, as shown by the arrowheads 24. In figure 4, the receptacle ]2is shown completely collapsed by being squeezed to release substantially all of the contents of the cavity containing said fluidso as to be wiped or applied on a surface 2~, such as a body.
~ ~ 4;~12 j The upper exposed surface 28 is preferably a thin-coated foil, a single plastic layer, such as polyetheylene or a laminate ;sheet material which is capable of being squeezed and compressed so as to meter out the contents of the reservoir and to progress-~ively expell the fluid contents of the receptacle 12 when thepackage 10 is squeezed between one's thumb and forefinger or against la surface, as best shown in figures 4, 6, 9, 11 and 15. The inside surface of the foil or other sheet material is generally coated or laminated with a polyethylene or polyester which provides the sealing surface and a surface which is chemically compatable for many fluids, such as inhalants, gels,ointments, liquids such as ~povidone iodine, (~libitane, Hibiclens - S-tuart Trust Ph~maceutical Co.
trademarks of a Co. in Wilmington, Delaware), chlorohexadine ~solutions, alcohol solutions, dyes, detergents, shampoos, or other Igermicidal composi-tions. In this connection, the packages of the ¦Ipresent invention are generally designed for medical or veterinar-ian use, since they are of the disposable -type after a single use or application. Other applicators, such as in the cosmetic industry ~where a liquid, gel or creams are used may be packaged and are considered within the scope of the present invention. For example, liquid make-up or make-up removers, hair coloring 'or dye' are all capable of being used with the applications of the present invention ~ sing an upper surface 28 made of a plastic or syn-thetic material, such as polyethylene which has some memory when squeezed, the release of finger pressure would ter.dto cause or generate a vacuum and some of the fluid deposited on a body surface 26 would be sucked back through the foam which might be desired when an excess of the medicament or dye has been applied on a body surface or other area.
In figures 5-9, there is shown alternate embodiments of ll f~
the invention. Figures 5 and 6 illustrate a device or swab package ~similar to that of figures l-A, but with a small split applicator pad 30 which forms a "butterfly" or inverted T with the larae limb lor top of the T forming the wiping applicator surface. The pad 30 is centrally disposed on the device and has a pair of slits 32, 34 which provides a much larger wiping surface of the head portion as compared to the head portion or wrap-around wiping surface of l~the device shown in figures 1-4. One of the advantages of this type lof construction is that it prevents a doctor's fingers with coming in contact with the body 26, should the fingers slip downward]y or forwardly. If they did, the fingers would simply contact the top r upper side of the wiping applicator surface. With this type of structure, a denser or stiffer urethane foam material havin~
,less pores per inch is preferred as the outwardly extending ends should stay in contact with the body or surface 26 and not flap loosely or curl when the applicator is vigorously wiped back and forth.
The modifications of figures 7-9 illustrate another ~Icentrally disposed applicator pad 40 suitably affixed to the lower 'Isurface of the receptacle 12. In this case, the pad 40 is of a generally small size so as to preclude or reduce the chances of ¦the fingers of a doctor from coming in contact with the foam or sponge-like applicator pad 40 and thereby contaminating same. The cut or score line 42 may be suitably formed as a single strike or line, double line or row. Also, -the line or cut may be straight or curved half moon or semi-lunar shaped or preferrably can form the shape of a Roman numerial I, as best shown in Figure 13. O-ther examples of the cut, score or weakened area are more particularly described in the aforesaid U.S. Patent No. 3,986,640.

, I I _ g 1, !
Figures 10 and 11 show a modifiecl swab applicator embodying a foam applicator tip 50 suitably affi.xed to the end 51 o:E a stem or hand]e 52 proxirnal to the cut or scored line 54 of the receptac]e 56. In such structure, it is preferable to use a stiffer material in lieu of the foil material. However, it is importan-t to note that the stiffer materia^l shou~.d be properly oriented so tha~ the score or cut line can be easily ruptured (oriented transverse to the stretched direction of -the material).
IlAlthough the fluid contents of the receptacle 56 will be expelled i' , .. .
at the proximal end of the foam pad 50, it will swish easily to the distal end of the pad as the fluid is further forced out of the receptacle 56. It should also be noted that the end of the stem or handle 52 may be affixed to an outside surface of the receptacle 56, in lieu of being internally disposed in the foam pad 50 as shown in figures 10 and 11.
l~l In figures 12-15, -the applicator pad 60 is internally ¦dlsposed within the cavity of the receptacle or reservoir. One of jthe advantages of this structure is that since the package forms : ¦lin effect a totally sealed construction, there is no chance of contamination of the applicator pad until rupture and actual use.
With the other types of swab packages, an outer wrap is necessary to maintain the applicator pad from particulate matter and also to retain sterility of the overall package prior -to its use. However, as a practlcal matter, a plurality of non-overwrapped applicators may be conveniently dis~ensed~from a multiple dispenser box which initially may be suitably sealed and sterilized when initially packed at the factory. Of course, after the package is opened, sterility cannot be guaranteed for the rest of its contents.
Although not shown because the foam is compressed, it is ~extremely preferable for the sponge or foam area in the vicinity il "
Il .
~.*~
~of -the cut or score line -to have a -transverse protrusion, head or thickened por-tion facing said cu-t or score line. This thickened portion or protrusion 62 is shown protruding from the cut or score line 64. The top or upper surEace 66 of the receptacle 68 is ~,preferably provided with a depression forming a rib 70. This rib ~70 serves to assist in pushing or forcing said applicator pad 60 through said cut or score line 64, when the package is bent or folded during use.
1~ Figure 12 merely illustrates a cross type of cut or Iscore line, in l.ieu of a straight line or line.having the shape ¦of Roman numeral I, as shown in figures 13-15. Even with this type of slitting, the pad 60 protrudes from the package, but only in a limited circular area or zone which may be desirable for certain lapplications, in contrast to the larger transverse wiping surface ~formed when the alternate package constructions are bent or folded.
I A surgical dressing or "Band-Aid" type of applicator package is shown in figure 16. As shown therein, the dressing is generally in the form of a cotton or synthetic pad 70 afEixed to the receptacle or reservoir 72 and both elements are suitably secured to an outer adhesive type material 74 having one or more removable layers or coverings, such as siliconized papers. Prefer-ably, a pair of such pealable papers 76 and 78 is provi.ded to 79 and its protect the adhesive~-tape qualities and to maintain the integrity lof the overall package, particularly the cotton or synthetic pad 70. In use, the protective paper material may be removed firs-t ,and then the receptacle can be cracked or ruptured todispense the fluid into the dressing or pad 70 or the reverse procedure is also possible. The application of the dressing on a wound is akin to that of a "Band-Aid" or other like dressing with the addition of a self-contained medicament. This embodiment of the invention is alsc, I .
D ~
adapted for use as a skin patch tester or through-the-skin dispenser or infuser.
Another modified packaye is the inhalant 80 shown in figure 17. As shown -therein, -the cotton or cellulose, rayon or iurethane pad 82 is affixed to the receptacle 84 and when the l,receptacle 84 is bent or folded upon itself, the cut or score line 86 is ruptured causiny the fluid to escape into the pad 82. The indentation or depression 88 in the package is like the depression ~70 of the package shown in figure 14. Such a feature provides a jwedge for pressing against the cut or score line 86 so as to easily cause the rupture of same without und~e bending forces. In this construction, the pad 82 need not have a protective covering as it is merely used as a porous absorber for the inhalan-t material which ,lis released from the receptable 84 into the pad 82 upon squeezing ,Ithe package together about the score line 86, as best shown by ~the phantom lines of Figure 17.
Figure 18 shows a scrub brush 90 with brlstles and with la rupturable package disposed within a sponge 92 secured to the !~ base or well 94 on the back of the brush. The bristles 96 form part of the generally rigid and generally perforated backing ele-ment 98. This backing member 98 may have suitable sides to aid in retaining the sponge 92 which may be suitably secured, such as ¦by adhesives, to the backing member 98. The sponge 92 may be ~,lsuitably slit along a line 100 so as to accommodate a receptacle 102 containing a germicidal composition or other scrubbing or cleansing solution. The receptacle 102 i~ suitably weakened or scored at 104 so as to split in the central portion of the scrub brush or receptacle and release the composition or other cleansing solution into the sponge 92 when the brush is bent or folded about a weakened area or zone 106 on opposite longitudinal side walls 108 , ll Il of the backing member 98, as best shown in Figure 19. My U.S.
Patent No. 4,181,446, granted January 1, 1980 disclosed such as foldable brush which could be adapted to contain the recep-tacle 102. However, in such an arrangement, the width of the receptable would be wider as the slit would have to be oriented longitudinally instead of transversely. Note that the germ-icidal solution may comprise povidine iodine, chlorohexedine, hexochlorphene, alcohol, etc. and/or a detergent in the form of powder or crystals which when suitably melted provide a cleans-ing, scrubbing and disinfecting composition. Other solutions, such as merthiolate, zephrin chloride in a liquid or a gel may also be used.
The relatively stiff or rigid sheet material having the weakened or scored zone is of a plastic, such as poly-styrene or a copolymer therof. In addition, a gas and/or a vapor barrier should be applied to the outer side of the receptacle to preclude water, vapor loss and entry of oxygen or evaporation of the receptacle's contents, such as alcohol. Such barriers may be coating or layers of materials, such as BA~TUFF (a trade-mark of ~merican Can Co.), SARAN (a Dow Chemical Co. trademark), Aclar, a fluorohalocarbon film, (a trademark of Allied Chemical, N.J), thin foil,etc. The score or cut pattern or patterns extend only partially through the material, and the use of a sealant or foil covering one or both outer faces of the sheet material may be used, if desired, where packaging requirements dictate such additional layers or coatings which serve other well known functions. For example, gas barriers, such as foil (aluminum preclude loss of product or active ingredients of the stored product. Also, they tend to keep water or the alcohol content of the product stable in order to have a normal or e~tended shelf life for the product. Other backing types of laminates embodying aluminum foil which may be employed with the invention comprise foil and pol~ethvlene- foil, polyester and polvethylere; o~ foil and a polyester.
jrc: ~-Polyester and s-tyrene sheets, however, do not exhibit ~as yood gas and water barrier characteristics. Better gas and Iwater barrier type packages are formed by butylated low density ,and high density polyetheylene~aminated to nylon,polyvinylidene chlorid~
(Saran), acrylic, polyester, and Aclar and other suitable coatings.
It should also be noted that the type of material used l~depends on the product to be packaged. For example, iodine attacks 'foil chemically changing it to aluminum iodide, which is a white ,Ipowder and the active iodine (free iodine) ls thus lost because it has an affinity for the foil, thereby weakening the iodine solution l(loss of the acti~e or free iodine). ~A polyester coating, however, l¦can be used to separate the iodine from the foil barrier. Bonding ¦lthe layer together, heat sealing the seams and containing the product over long periods of time involve a constant search for better and stronger combinations oE materials and coatings, so that a sound package is formed compl.etely free of fai].ure (leakage) ~or deterioration of shelf life where, say the active materials in the iodine solutions are dissipated gradually due to being .absorbed or reacted with the polyester or polyetheylene coatings.
Il In Figures 20-23, a further modificationSof the invention ¦are illustrated. As shown therein, a pair of reservoirs 100 and 102 having necked down portions 104 leading to a fanned out proximal portion 106. The function of the funneling or.necked down effect is to provide a controllable flow or to slow down the flow rate of .the fluid being forced out of the reservoirs 100 and 102. The fanned out portions 104 distribute the fluid more evenly over -the ~entire transverse length of the swab material 108. In this ~,embodiment, the swab material 108 is a urethane foam material shaped in the form of a half round adhered to each side of the weakened area 110. Although two reservoirs are shown, it is possible to provide a single reservoir with a pair of oppositely ,"
;
l 2 opposed sections joined together at a centrally disposed necked ~down portion having a further centrally disposed fanned out portion ,with the weakened area central to the fanned out area.
With a single reservoir, the fluid has a tendency to ~rush out into -the foam or sponge and through it at an almost uncontrolable rate, thereby not uniformly-wetting the entire sponge initially. Also, it passes through the sponge creatiny drips and spillage and generally messes up a neat and clean applicationof thefluid. Also, such a construction does not leave any further fluid in reserve Eor further use in scrubbing.
With a dual cavity unit, since the cavities are smaller lland contain less fluid than a single cavity with the same total j~volume, there is more surface tension and less chance for fluid ¦to spill out of the cavities during movement of the cavities in the web material which is being pulled through, filled and sealed on jthe same machine.
In addition, this structure makes the reservoir por-tion lmore rigid because there is more definition implied by the config-uration of a dual, or double necked down-fanned out reservoir.
The multiple compound shapes or ribbinc3 effect pressed into or ~vacuum formed in the foil laminate gives it superior strength which is not naturally inherent or formed in such materials.
Thus, the swab is stronger and will crack more easily when desired lland the limbs of the swab will meet in a better back-to-back ¦¦fashion and have less likelyhood of sizzoring since the structure lends itself to a more sharper and distinct action when the package is activated by bending together the opposite ends for opening ~the reservoir. Figure 23 shows an applicator package in a 'iperipherally-sealed paper wrapper 112 having a scored or weakened transverse perforated line 114 which permits the foam pad or applicator to burst through the wrapper upon activation and use of Il , 1. :
! the applicator package. This eliminates contamination of the foam pad in use. Of course, if desired, pealable end flaps 116 may be employed to conventionally open an end of the paper wrapper so as to provide access to the applicator.
~1 It should also be recognized that the package of Figures 20-22 can be used to dispense as epoxy cement. One of the two reservoirs can store any conventional filler or epoxy resin and the other reservoir can store the appropriate hardener or activator. Such a two-component epoxy system çan be designed with the necked portion 104 of each reservoir meeting adjacent each other at their ends in the centèr of the package below the split 110 whlch need not necessarily be transversely disposed across the entire width of the packageO Of coursel with such a ~l construction, there would be no need for the fanned-out portions i 106 as the meteriny of the epoxy would be just to a small spot or ,1l area where the split 110 would be provided in the immediate Il vicinity of the ends of the necked-down portions 104~
Il If a three or four cavity applicator system is deslred for use in dying applications or other uses, the package can simply be arranged to contain, for example, two reservoirs on one I¦ or both sides by simply dividing the reservoir (100 or 102 or ¦I both) in half with a separation or barrier wall disposed ¦I horizontally or longitudinally down the center`of the package.
jl This construction could then be used in any system where three or four reservoir cavities are required.
1 Although the present invention has been described in ¦ some detail by way of illustration and example for purposes of clarity of understanding, i~ will, of course, be understood that ¦I various changes and modifications may be made in the form, details, and arrangements of the parts without departing from the scope of the invention as set forth in the following claims.

l l
ICnown in the prior art is a package for a flowable product, namely United States Patent No~ 3,986,640, granted October 19, 1976 to Sanford Redmond. This patent teaches a lpackage for a flowable product wherein thê package includes a relatively stiff, but flexible material and a flexible material between which the flowable product to be packaged is contained and around which flowable product the materials are affixed to each other~ The relatively stiff, but flexible material is cut 'I through or partially through in an interrupted pattern and, when ;cut through, at least one side of the relatively stiff, but flexible material, at least in the area of the cut pattern, being ! covered with a sealant, which sealant preferably is a foil, the package, when bentl opening up along the cut patt.ern to dispense the flowable product from the package. The patent also discloses and teaches the flexible material which is used Eor making such a ~I package.
,~l One of the disadvantages of this package is the uncontrollable rate at which the flowable material is squeezed and discharged out of the package~ Due to its form of construction, ` there is no control to the flow from the package, and that it does lnot teach any specific type of packages, such as applicator packages for specific needs in the medical profession. Also, the package of ~.S.P. No. 3,986,640 does not teach the utilization of a multi-cavity reservoir for storage of the flowable product.
With such a multi-cavity applicator package, one can achieve a 'controllable flow of the product from the package during use.
Accordingly, although the prior art package noted herein functions ' in dispensing a flowable product from the package, it lacks the ,1 - 2 ,1 teaching of specific applicator packages which can be used in diverse app].ications. Thus, the packages of the present lnventi.on overcome the problems heretofore encountered with this prior art package and overcomes the disadvantages, and provides a number of applicator packages which have specific applications, particularly in the medical and veterinarian fields. other packages for use in still other fields are also disclosed in the instant application.
.Accordingly, one of the primary objects of the present invention is to provide an applicator package having distal ends comprising a foam applicator pad and having a backing member adjacent thereto: the backing member being formed of a relatively rigid, flat and stiff plastic sheet material having a vapor and gas barrier coating and a laminated deformable plastic coated foil material having at least one reservoir containing a flowable product, such as a liquid, being sealed to the flat and stiff sheet material for containing the contents of the reservoir therebetween; the flat and stiff sheet material having a centrally disposed linear weakened portion in the surface of the flat and stiff sheet material and the weakened portion being transversely disposed of the flat and stiff sheet material with the foam applicator pad secured to the outer surface of the flat and stiff sheet material and centrally disposed over the weakened portion;
the weakened portion rupturing upon forcing the distal ends of the applicator package towards each other and about the weakened portion, so as to compress the reservoir of the deformable plastic coated foil material hy crushing opposite sides of the reservoir against each other such that substantially all of the flowable product in the reservoir can be controllably released into the applicator pad for wiping applications upon pressure completely deforming and mg/J~ - 3 -1 .1Lt;~
collapsing the plastic coated foi.l material; and the foam applicator pad is a foam block having opposite slits partially throuyh the foam block so that when the distal ends are squee~ed together, the foam block assumes an inverted T-shape with a large wiping contact surface area.
The foregoing object and other objects of the present invention will become apparent upon reading the following specification and referring to the accompanying drawings, which form a material part of this disclosure.
The invention accordingly consists in the features of construction, combination of elements, and arrangements of parts, which will be exemplified in the preferred constructions hereinafter described, and of which the scope will be indicated by the claims.

BACKGROUND OF THE INVENTION
This invention generally relates to swab articles, such as swab packages, swab sticks or applicators, scrub brushes with a swabbing or wiping surface, and to other similar type packages adapted for use as bandaids, inhalants and the like, such as skin preping or pre-operative scrubs having cleansing agents, surgica]. scrubs, skin preps for cardiac electrodes and tincture or dye applicators, skin patch testing and through-the-skin dispensing of hormones or medic-aments including time release formulations (such as insulin time release compounds). The swab packages of the invention are basically of the rupturable type embodying a receptacle for fluids, such as ointments, powders, germicides, liquids, gels, pastes, etc. Also, the swab packages include an applicator pad or surface or other like structure, and may be, if desired, suitably packaged with an overwrap to provide sterility.
As best shown in figures 1-4, there is shown a swab package 10 embodying a receptacle or reservoir 12 and an externally mounted applicator 14, such as a gauze pad, plastic foam pad or synthetic cotton or fabric pad. The plastic foam material may comprise a urethane foam material or a natural latex foam. The construction of the receptacle or reservoir 12 is basically of the type disclosed in U.S.P. No. 3,986,640 as noted hereinbefore.
jrc:~ -Thus, for example, wi-th the present invention, the receptacle 12 may compriseon one side thereof a thin, relatively stiff laminate type of plastic sheet material 16, such as an extruded polystyrene, acrilonitride or copolymer with poly-styrene with or without special coatings, such as vapor or gas barriers or heat sealants or bonding coats. The material may be, if desired, initially treated by stretching so as to orient the structure for providing additional strength in one direction only, whereby the material is capable of splitting easily in a direction orthogonal thereto, provided a score line or other weakened area 18 is made a part of the receptacle 12. Such a score or cut line or weakened area 18 is provided on the side or surface 20 to which the applicator 14 is mounted or otherwise secured to the receptacle 12, by means such as adhesives, heat sealing, ultrasonic or electronic impulse bonding or other like securing means. Subsequent to the stretch-ing of the base material, the material is then further provided with any desired laminate coating, such as spraying, or adhering another sheet of material directly on the base material.
The periphery 20 of the receptacle 12 is provided with a marginal seal such as a heat seal, to retain the fluid in said receptacle 12 from escaping therefrom until the receptacle 12 is fractured or ruptured, as will be further described herein in greater detail.
In figures 3-4, the package of figures 1 and 2 is shown initially partially opened b~ bending or folding opposite ends of the package 10, thereby weakening the pre-weakened area or zone 18 so as to finally rupture same. The fluid 22 is thus released to flow directly into the applicator 14, as shown by the arrowheads 24. In figure 4, the receptacle ]2is shown completely collapsed by being squeezed to release substantially all of the contents of the cavity containing said fluidso as to be wiped or applied on a surface 2~, such as a body.
~ ~ 4;~12 j The upper exposed surface 28 is preferably a thin-coated foil, a single plastic layer, such as polyetheylene or a laminate ;sheet material which is capable of being squeezed and compressed so as to meter out the contents of the reservoir and to progress-~ively expell the fluid contents of the receptacle 12 when thepackage 10 is squeezed between one's thumb and forefinger or against la surface, as best shown in figures 4, 6, 9, 11 and 15. The inside surface of the foil or other sheet material is generally coated or laminated with a polyethylene or polyester which provides the sealing surface and a surface which is chemically compatable for many fluids, such as inhalants, gels,ointments, liquids such as ~povidone iodine, (~libitane, Hibiclens - S-tuart Trust Ph~maceutical Co.
trademarks of a Co. in Wilmington, Delaware), chlorohexadine ~solutions, alcohol solutions, dyes, detergents, shampoos, or other Igermicidal composi-tions. In this connection, the packages of the ¦Ipresent invention are generally designed for medical or veterinar-ian use, since they are of the disposable -type after a single use or application. Other applicators, such as in the cosmetic industry ~where a liquid, gel or creams are used may be packaged and are considered within the scope of the present invention. For example, liquid make-up or make-up removers, hair coloring 'or dye' are all capable of being used with the applications of the present invention ~ sing an upper surface 28 made of a plastic or syn-thetic material, such as polyethylene which has some memory when squeezed, the release of finger pressure would ter.dto cause or generate a vacuum and some of the fluid deposited on a body surface 26 would be sucked back through the foam which might be desired when an excess of the medicament or dye has been applied on a body surface or other area.
In figures 5-9, there is shown alternate embodiments of ll f~
the invention. Figures 5 and 6 illustrate a device or swab package ~similar to that of figures l-A, but with a small split applicator pad 30 which forms a "butterfly" or inverted T with the larae limb lor top of the T forming the wiping applicator surface. The pad 30 is centrally disposed on the device and has a pair of slits 32, 34 which provides a much larger wiping surface of the head portion as compared to the head portion or wrap-around wiping surface of l~the device shown in figures 1-4. One of the advantages of this type lof construction is that it prevents a doctor's fingers with coming in contact with the body 26, should the fingers slip downward]y or forwardly. If they did, the fingers would simply contact the top r upper side of the wiping applicator surface. With this type of structure, a denser or stiffer urethane foam material havin~
,less pores per inch is preferred as the outwardly extending ends should stay in contact with the body or surface 26 and not flap loosely or curl when the applicator is vigorously wiped back and forth.
The modifications of figures 7-9 illustrate another ~Icentrally disposed applicator pad 40 suitably affixed to the lower 'Isurface of the receptacle 12. In this case, the pad 40 is of a generally small size so as to preclude or reduce the chances of ¦the fingers of a doctor from coming in contact with the foam or sponge-like applicator pad 40 and thereby contaminating same. The cut or score line 42 may be suitably formed as a single strike or line, double line or row. Also, -the line or cut may be straight or curved half moon or semi-lunar shaped or preferrably can form the shape of a Roman numerial I, as best shown in Figure 13. O-ther examples of the cut, score or weakened area are more particularly described in the aforesaid U.S. Patent No. 3,986,640.
' ~
, I I _ g 1, !
Figures 10 and 11 show a modifiecl swab applicator embodying a foam applicator tip 50 suitably affi.xed to the end 51 o:E a stem or hand]e 52 proxirnal to the cut or scored line 54 of the receptac]e 56. In such structure, it is preferable to use a stiffer material in lieu of the foil material. However, it is importan-t to note that the stiffer materia^l shou~.d be properly oriented so tha~ the score or cut line can be easily ruptured (oriented transverse to the stretched direction of -the material).
IlAlthough the fluid contents of the receptacle 56 will be expelled i' , .. .
at the proximal end of the foam pad 50, it will swish easily to the distal end of the pad as the fluid is further forced out of the receptacle 56. It should also be noted that the end of the stem or handle 52 may be affixed to an outside surface of the receptacle 56, in lieu of being internally disposed in the foam pad 50 as shown in figures 10 and 11.
l~l In figures 12-15, -the applicator pad 60 is internally ¦dlsposed within the cavity of the receptacle or reservoir. One of jthe advantages of this structure is that since the package forms : ¦lin effect a totally sealed construction, there is no chance of contamination of the applicator pad until rupture and actual use.
With the other types of swab packages, an outer wrap is necessary to maintain the applicator pad from particulate matter and also to retain sterility of the overall package prior -to its use. However, as a practlcal matter, a plurality of non-overwrapped applicators may be conveniently dis~ensed~from a multiple dispenser box which initially may be suitably sealed and sterilized when initially packed at the factory. Of course, after the package is opened, sterility cannot be guaranteed for the rest of its contents.
Although not shown because the foam is compressed, it is ~extremely preferable for the sponge or foam area in the vicinity il "
Il .
~.*~
~of -the cut or score line -to have a -transverse protrusion, head or thickened por-tion facing said cu-t or score line. This thickened portion or protrusion 62 is shown protruding from the cut or score line 64. The top or upper surEace 66 of the receptacle 68 is ~,preferably provided with a depression forming a rib 70. This rib ~70 serves to assist in pushing or forcing said applicator pad 60 through said cut or score line 64, when the package is bent or folded during use.
1~ Figure 12 merely illustrates a cross type of cut or Iscore line, in l.ieu of a straight line or line.having the shape ¦of Roman numeral I, as shown in figures 13-15. Even with this type of slitting, the pad 60 protrudes from the package, but only in a limited circular area or zone which may be desirable for certain lapplications, in contrast to the larger transverse wiping surface ~formed when the alternate package constructions are bent or folded.
I A surgical dressing or "Band-Aid" type of applicator package is shown in figure 16. As shown therein, the dressing is generally in the form of a cotton or synthetic pad 70 afEixed to the receptacle or reservoir 72 and both elements are suitably secured to an outer adhesive type material 74 having one or more removable layers or coverings, such as siliconized papers. Prefer-ably, a pair of such pealable papers 76 and 78 is provi.ded to 79 and its protect the adhesive~-tape qualities and to maintain the integrity lof the overall package, particularly the cotton or synthetic pad 70. In use, the protective paper material may be removed firs-t ,and then the receptacle can be cracked or ruptured todispense the fluid into the dressing or pad 70 or the reverse procedure is also possible. The application of the dressing on a wound is akin to that of a "Band-Aid" or other like dressing with the addition of a self-contained medicament. This embodiment of the invention is alsc, I .
D ~
adapted for use as a skin patch tester or through-the-skin dispenser or infuser.
Another modified packaye is the inhalant 80 shown in figure 17. As shown -therein, -the cotton or cellulose, rayon or iurethane pad 82 is affixed to the receptacle 84 and when the l,receptacle 84 is bent or folded upon itself, the cut or score line 86 is ruptured causiny the fluid to escape into the pad 82. The indentation or depression 88 in the package is like the depression ~70 of the package shown in figure 14. Such a feature provides a jwedge for pressing against the cut or score line 86 so as to easily cause the rupture of same without und~e bending forces. In this construction, the pad 82 need not have a protective covering as it is merely used as a porous absorber for the inhalan-t material which ,lis released from the receptable 84 into the pad 82 upon squeezing ,Ithe package together about the score line 86, as best shown by ~the phantom lines of Figure 17.
Figure 18 shows a scrub brush 90 with brlstles and with la rupturable package disposed within a sponge 92 secured to the !~ base or well 94 on the back of the brush. The bristles 96 form part of the generally rigid and generally perforated backing ele-ment 98. This backing member 98 may have suitable sides to aid in retaining the sponge 92 which may be suitably secured, such as ¦by adhesives, to the backing member 98. The sponge 92 may be ~,lsuitably slit along a line 100 so as to accommodate a receptacle 102 containing a germicidal composition or other scrubbing or cleansing solution. The receptacle 102 i~ suitably weakened or scored at 104 so as to split in the central portion of the scrub brush or receptacle and release the composition or other cleansing solution into the sponge 92 when the brush is bent or folded about a weakened area or zone 106 on opposite longitudinal side walls 108 , ll Il of the backing member 98, as best shown in Figure 19. My U.S.
Patent No. 4,181,446, granted January 1, 1980 disclosed such as foldable brush which could be adapted to contain the recep-tacle 102. However, in such an arrangement, the width of the receptable would be wider as the slit would have to be oriented longitudinally instead of transversely. Note that the germ-icidal solution may comprise povidine iodine, chlorohexedine, hexochlorphene, alcohol, etc. and/or a detergent in the form of powder or crystals which when suitably melted provide a cleans-ing, scrubbing and disinfecting composition. Other solutions, such as merthiolate, zephrin chloride in a liquid or a gel may also be used.
The relatively stiff or rigid sheet material having the weakened or scored zone is of a plastic, such as poly-styrene or a copolymer therof. In addition, a gas and/or a vapor barrier should be applied to the outer side of the receptacle to preclude water, vapor loss and entry of oxygen or evaporation of the receptacle's contents, such as alcohol. Such barriers may be coating or layers of materials, such as BA~TUFF (a trade-mark of ~merican Can Co.), SARAN (a Dow Chemical Co. trademark), Aclar, a fluorohalocarbon film, (a trademark of Allied Chemical, N.J), thin foil,etc. The score or cut pattern or patterns extend only partially through the material, and the use of a sealant or foil covering one or both outer faces of the sheet material may be used, if desired, where packaging requirements dictate such additional layers or coatings which serve other well known functions. For example, gas barriers, such as foil (aluminum preclude loss of product or active ingredients of the stored product. Also, they tend to keep water or the alcohol content of the product stable in order to have a normal or e~tended shelf life for the product. Other backing types of laminates embodying aluminum foil which may be employed with the invention comprise foil and pol~ethvlene- foil, polyester and polvethylere; o~ foil and a polyester.
jrc: ~-Polyester and s-tyrene sheets, however, do not exhibit ~as yood gas and water barrier characteristics. Better gas and Iwater barrier type packages are formed by butylated low density ,and high density polyetheylene~aminated to nylon,polyvinylidene chlorid~
(Saran), acrylic, polyester, and Aclar and other suitable coatings.
It should also be noted that the type of material used l~depends on the product to be packaged. For example, iodine attacks 'foil chemically changing it to aluminum iodide, which is a white ,Ipowder and the active iodine (free iodine) ls thus lost because it has an affinity for the foil, thereby weakening the iodine solution l(loss of the acti~e or free iodine). ~A polyester coating, however, l¦can be used to separate the iodine from the foil barrier. Bonding ¦lthe layer together, heat sealing the seams and containing the product over long periods of time involve a constant search for better and stronger combinations oE materials and coatings, so that a sound package is formed compl.etely free of fai].ure (leakage) ~or deterioration of shelf life where, say the active materials in the iodine solutions are dissipated gradually due to being .absorbed or reacted with the polyester or polyetheylene coatings.
Il In Figures 20-23, a further modificationSof the invention ¦are illustrated. As shown therein, a pair of reservoirs 100 and 102 having necked down portions 104 leading to a fanned out proximal portion 106. The function of the funneling or.necked down effect is to provide a controllable flow or to slow down the flow rate of .the fluid being forced out of the reservoirs 100 and 102. The fanned out portions 104 distribute the fluid more evenly over -the ~entire transverse length of the swab material 108. In this ~,embodiment, the swab material 108 is a urethane foam material shaped in the form of a half round adhered to each side of the weakened area 110. Although two reservoirs are shown, it is possible to provide a single reservoir with a pair of oppositely ,"
;
l 2 opposed sections joined together at a centrally disposed necked ~down portion having a further centrally disposed fanned out portion ,with the weakened area central to the fanned out area.
With a single reservoir, the fluid has a tendency to ~rush out into -the foam or sponge and through it at an almost uncontrolable rate, thereby not uniformly-wetting the entire sponge initially. Also, it passes through the sponge creatiny drips and spillage and generally messes up a neat and clean applicationof thefluid. Also, such a construction does not leave any further fluid in reserve Eor further use in scrubbing.
With a dual cavity unit, since the cavities are smaller lland contain less fluid than a single cavity with the same total j~volume, there is more surface tension and less chance for fluid ¦to spill out of the cavities during movement of the cavities in the web material which is being pulled through, filled and sealed on jthe same machine.
In addition, this structure makes the reservoir por-tion lmore rigid because there is more definition implied by the config-uration of a dual, or double necked down-fanned out reservoir.
The multiple compound shapes or ribbinc3 effect pressed into or ~vacuum formed in the foil laminate gives it superior strength which is not naturally inherent or formed in such materials.
Thus, the swab is stronger and will crack more easily when desired lland the limbs of the swab will meet in a better back-to-back ¦¦fashion and have less likelyhood of sizzoring since the structure lends itself to a more sharper and distinct action when the package is activated by bending together the opposite ends for opening ~the reservoir. Figure 23 shows an applicator package in a 'iperipherally-sealed paper wrapper 112 having a scored or weakened transverse perforated line 114 which permits the foam pad or applicator to burst through the wrapper upon activation and use of Il , 1. :
! the applicator package. This eliminates contamination of the foam pad in use. Of course, if desired, pealable end flaps 116 may be employed to conventionally open an end of the paper wrapper so as to provide access to the applicator.
~1 It should also be recognized that the package of Figures 20-22 can be used to dispense as epoxy cement. One of the two reservoirs can store any conventional filler or epoxy resin and the other reservoir can store the appropriate hardener or activator. Such a two-component epoxy system çan be designed with the necked portion 104 of each reservoir meeting adjacent each other at their ends in the centèr of the package below the split 110 whlch need not necessarily be transversely disposed across the entire width of the packageO Of coursel with such a ~l construction, there would be no need for the fanned-out portions i 106 as the meteriny of the epoxy would be just to a small spot or ,1l area where the split 110 would be provided in the immediate Il vicinity of the ends of the necked-down portions 104~
Il If a three or four cavity applicator system is deslred for use in dying applications or other uses, the package can simply be arranged to contain, for example, two reservoirs on one I¦ or both sides by simply dividing the reservoir (100 or 102 or ¦I both) in half with a separation or barrier wall disposed ¦I horizontally or longitudinally down the center`of the package.
jl This construction could then be used in any system where three or four reservoir cavities are required.
1 Although the present invention has been described in ¦ some detail by way of illustration and example for purposes of clarity of understanding, i~ will, of course, be understood that ¦I various changes and modifications may be made in the form, details, and arrangements of the parts without departing from the scope of the invention as set forth in the following claims.
