Abstract: The device is for the use by a woman and has a flat shield portion and an extendible pouch 42 with an open end joined to the shield portion and a closed end spaced from the open end. The closed end has a retention device 41 therein for urging the closed end into an expanded position for retaining the pouch in place.

Description: This invention relates to prophylactic devices. More particularly, this invention relates to prophylactic devices which are highly effective in preventing the transmission of venereal diseases and AIDS. Even more particularly, this invention relates to prophylactic devices which may be used by a woman. With the widespread occurrence of venereal diseases and AIDS (Acquired Immune Deficiency Syndrome), there is an increasing need for an effective means of preventing the transmission of such diseases through sexual contact. Conventional means for preventing the transmission of such diseases include the use of condoms, diaphragms, gels, creams etc. However, such conventional means are not totally effective, even when they are used in combination with one another. There has not heretofore been provided an effective prophylactic device for a woman which prevents the transmission of diseases during sexual intercourse. A prior prophylactic device for use by a woman is known from US-A-4 004 591 which comprises two wings or flaps at an open end of a tubular member which has a closed end spaced from the open end. In use, the tubular member is suitably inserted in the vaginal canal. However retention of the tubular member within the vaginal canal relies merely on the natural curvature of the canal and, as an added precaution, the possible use of a lubricant on the interior of device so that, during coitus, there is no undue frictional engagement of the inner surface of the device by the exterior surface of the male organ. An object of the present invention is to provide a prophylactic device for use by a woman which will provide improved retention within the vaginal canal as well as shielding perineum regions to prevent the contact of bodily fluids with such regions. In accordance with the present invention there is provided a prophylactic device for use by a woman according to Claim 1. The retention device is advantageous as it will be gripped and retained in position by the muscles in the vagina of the female. The invention is described in more detail hereinafter with reference to the accompanying drawings, wherein like reference characters refer to the same parts throughout the several views and in which: Figure 1 is a front perspective view of one embodiment of prophylactic device of this invention; Figure 2 is a side elevational view of one embodiment of prophylactic device shown in Figure 1; Figure 3 illustrates the embodiment of prophylactic device of Figure 1 while being worn by a female person; Figure 4 is a perspective view of another embodiment of prophylactic device of the invention for use by a female person; Figure 5 is a perspective view of another embodiment of prophylactic device of the invention, Figure 6 is a partially cut away, perspective view of another embodiment of prophylactic device of the invention; Figure 6A is a cross-sectional view of a portion of the device of Figure 6; Figure 7 is a cross-sectional view of a portion of another embodiment of the invention; Figure 8 is a perspective view illustrating another embodiment of prophylactic device of this invention; Figure 9 is a side view of the device illustrated in Figure 8; Figure 10 is a perspective view of another embodiment of prophylactic device of this invention; Figure 11 is a perspective view of yet another embodiment of a device of this invention; Figure 12 is a front perspective view of a mold which is useful in the production of a device of this invention; Figures 13a and 13b illustrate a preferred manner of telescoping and rolling the pouch member of a device of this invention; Figure 13c shows a device of the invention in which the pouch member is rolled; Figure 14 is a perspective view of an anatomically configured embodiment of the invention illustrating an arrangement of supporting straps; Figure 15 is a fragmentary sectional view taken along the line 15-15 in Figure 14; Figure 15a is a view showing the prophylactic device of Figure 15 in a first extended position for piloting the pouch portion thereof into a body cavity of a female person; Figure 15b is a sectional view showing the pouch portion of the prophylactic device of Figure 16 in a fully extended position within the body cavity of a female person; Figure 15c is a sectional view showing the dimensional relationship of an anatomically configured prophylactic device with the pouch portion thereof extended and in spaced relationship to an erected penis within a vaginal canal to provide freedom of and lateral movement with respect to the inner walls of the extended pouch portion of such prophylactic device: Figure 15d is a fragmentary view of the pouch wall at the clitoral region of a vaginal canal; Figure 15e is a fragmentary view of a stroking roll in the pouch wall of Figure 15d; Figure 16 is a diagrammatic view of a further embodiment of an anatomically configured hermaphroditic prophylactic device on a female person; Figure 17 is an enlarged fragmentary detail of a releasable fastener for securing a shield portion of the prophylactic devices of either Figure 14 or Figure 16 to garments or components thereof; Figure 18 is a diagrammatic view of dipping and tilting steps in a process of the present invention for manufacturing anatomically configured prophylactic devices; Figure 19 is a diagrammatic view showing a stripping step of such process steps of Figure 18; Figure 20 shows a rolling step wherein telescoped segments of the pouch are rolled into generally the same plane as that of the shield portion of such prophylactic device; and Figure 21 is a sectional view taken along the line 21-21 of Figure 25; Figure 21a is an enlarged sectional view of a segment of a partially detelescoped pouch; Figure 22 is a perspective view of a first fold step in packaging a prophylactic device formed by the steps of Figures 18 through 20; Figures 22a-22c are perspective view of an embodiment for folding the prophylactic device; Figure 23 is a rolling step for configuring the folded prophylactic device of Figure 22 in a tubular form for subsequent packaging; Figure 24 is an exploded view of a folded and rolled prophylactic device in an aligned, preassembled relationship with a tubular container for such prophylactic device; Figure 25 is a front elevational view of another embodiment of the prophylactic device; Figure 26 is an end elevational view of the embodiment of Figure 25; Figure 27 is a side elevational view of the Figure 25 embodiment; and Figure 28 is a perspective view of an inelastic plastic film embodiment of the present invention. Detailed Description of preferred embodiments of the Invention In Figures 1 and 2 there is illustrated one embodiment of a prophylactic device 10 which is in the form of a garment (i.e., a brief) which can be worn around the pelvic region. The garment includes an elongated hollow pouch 12 having a first end 14 which is closed and a second end 16 which is open. The pouch has a thin wall member which is flexible and elastic. Preferably the pouch is made of rubber which may be natural or synthetic. Other synthetic materials can also be used (e.g., polyurethane, polyvinylchloride, silicone elastomer, etc.). The thickness of the wall member is in the range of about 0.0127 to 2.54mm (0.0005 to 0.1 inch), and preferably in the range of about 0.254 to 0.127mm (0.001 to 0.005 inch). The second end of the pouch, i.e., the open end is attached to the garment in the manner shown in Figure 1 in a manner such that a portion of the garment forms a flange around the circumference of the opening in the pouch. Preferably the pouch is molded as an integral part of the garment. Alternatively, the pouch may be formed separately and then bonded to a corresponding opening in the garment. For example, the pouch may be permanently bonded to the garment or it may be detachably connected by means of adhesive, or with snaps, or with a fastener system of the type including an elongated bead or ridge on one component and an expandable receptive groove on the other component (e.g., such as is common with certain sandwich bags). As illustrated in Figures 1 and 2, the hollow pouch may be invertable. In these views the pouch is shown in dotted lines to illustrate the position of the pouch within the vagina of a female person wearing the garment. When putting on the garment, the pouch may be in the outward position illustrated in these figures. It is also easier to apply desired lubricants and a spermatocide (e.g., such as that commercially available under the Registered Trade Mark Nonoxonal 9) to either the interior or exterior of the pouch. Typically these materials are applied to both the interior and exterior surfaces of the pouch. Then the pouch is inverted and inserted into the vagina (as illustrated in Figure 3). The closed end 14 of the pouch includes a resilient member which is adapted to be gripped and retained in position by the vaginal muscles (i.e., the labia muscles). Thus, when the pouch in inserted into the vagina as illustrated in Figure 3, the labia muscles are capable of gripping and retaining the end 14 of the pouch in the position shown. The resilient member at the closed end of the pouch may be a resilient disc 50 (as illustrated in Figure 7) which is preferably flexible. The disc may be made of rubber of plastic. Preferably it is molded as an integral part of the pouch wall 52. Another embodiment of resilient member is illustrated in Figures 6 and 6A where it comprises a disc member 40 which includes a ring shaped spring or wire 41. The disc 40 may be deformed or folded to facilitate insertion into the vagina, and then the spring or wire 41 urges the disc member back to its original circular shape. The disc member 40 may be formed as an integral part of the wall member of the pouch 42 or it may be formed separately and then bonded to the wall member. Another embodiment of the prophylactic device 20 is illustrated in Figure 4. In this embodiment, the hollow pouch 22 has a closed end 23 and an open end 24. The open end of the pouch is attached to and surrounded by the continuous flange member 25, as illustrated. The flange extends outwardly at least 25.4mm (one inch), and preferably at least 76.2mm (three inches), around the open end of the pouch. The flange member in the devices of this invention may be both flexible and elastic, although neither or such features is required. For example, the flange may be flexible but nonelastic. It is also possible for the flange to be nonflexible (e.g. a plastic member). It is necessary for the flange to be liquid impermeable, however. In the embodiment shown in Figure 4, the flange member has a plurality of strap members 26 secured thereto. These strap members are connected at their opposite ends to band 26 which may be worn around the waist or around the pelvic region of the female person using this device. The flange member and the pouch prevent transmission of sperm and diseases from one person to the other. In Figure 5, there is illustrated another embodiment 30 of prophylactic device of the invention. The device comprises an elongated hollow pouch or sheath 33 which is closed at its outer end 32. The opposite end 34 is open and it is attached or secured to flange member 35. The flange member extends outwardly around the circumference of the opening in the pouch at least 25.4mm (one inch), and preferably at least 76.2mm (three inches). Strap members 36 are secured at one end to flange member 35 and are secured at the opposite end to band 37 which may be worn around the waist or around the pelvic region of the person using this device. The pouch and the flange member prevent the transmission of diseases from one person to the other. The pouch also prevents sperm from being transmitted. Of course, the device of figure 5 could instead be in the form of a brief to be worn by the person using it, if desired. In Figures 8 and 9 there is illustrated another embodiment of prophylactic device of the invention in which the pouch member is detachable. Thus, there is shown an elongated pouch member 60 having a closed end 61 and an open end 63. Surrounding open end 63 is a rim member 62 which is adapted to lay against flange 64 and may be detachably secured to flange 64 by means of adhesive, for example. Other useful means for securing rim 62 to flange 64 include snaps, buttons, adhesive tape, bead and groove fastener systems, hook and loop fastener systems, etc. In the arrangement of Figures 8 and 9, for example, the pouch member may be detached and discarded after use. The flange member 64 may be part of a garment (such as illustrated in Figures 1 and 2) or it may be the type shown in Figures 4 and 5. Figure 10 illustrates another embodiment of prophylactic device of this invention. In this embodiment, an elongated hollow pouch 70 has one closed end 71 and an open end 73. Flange member 74 surrounds the circumference of the open end 73, as illustrated. Strap members 74 are detachably secured to flange member by means of conventional snaps 76. Thus the pouch and flange may be detached and discarded after use. In yet another variation, the pouch member 70 may be used without strap members. For example, the flange 74 may be secured to the skin of the person wearing the device by means of adhesive or with adhesive tape, if desired. Figure 11 illustrates another embodiment of device 80 of the invention comprising strap or belt member 82, flange member 84, and elongated hollow pouch 85. The lower end of the pouch is open and the upper end is closed. The flange member extends from one side of the belt to the other, as illustrated. In the various embodiments of prophylactic devices of this invention, the sizes and thicknesses of the materials may vary. For example, the pouch member may have a length in the range of about 25.4 to 254mm (1 to 10 inches) (preferably about 10.1 to 152mm) (4 to 6 inches) and a diameter of about 25 to 101mm (1 to 4 inches). Although the pouch member may have a uniform diameter throughout its length, the diameter could vary if desired. The thickness of the wall material of the pouch member and the flange member may also vary. For example, it may be as thin as 0.0127mm (0.0005 inch) or as thick as 2.54mm (0.1 inch). Preferably it is in the range of about 0.254 to 0.127mm (0.001 to 0.005 inch). The pouch and the flange are preferably made of elastic, impermeable material such as natural rubber or synthetic rubber (e.g., silicone rubber). Useful materials also include nonelastic materials such as plastic (e.g., polyurethane, polyvinylchloride, etc.). The flange member extends outwardly around the open end of the pouch at least 25.4mm (one inch), preferably 76.2mm (three inches), and more preferably at least 127mm (five inches). If desired, the flange member may be thicker than the wall portion of the pouch. The closed end portion of the prophylactic devices is resilient as described above with respect to Figs 6, 6a and 7. It has been found that the pouch is held in position in the vagina by natural physiological force during and after intercourse. The thickness of the closed end portion may vary. Figure 12 is a perspective view of a preferred type of mold 100 which is useful in making devices of the invention which are in the form of a brief. The mold includes a general shape of a brief with an elongated protrusion 102 in the shape and size desired for the pouch member. The mold may be made of any suitable material such as ceramic, glass, hard plastic, etc. The mold is dipped into the material to be used in making the device (e.g., natural rubber latex) and then removed. After the rubber cures or dries, the brief which is so formed can be removed from the mold. Leg openings are made in the sides of the brief. Figures 13a and 13b illustrate a preferred and convenient manner for telescoping and rolling the pouch member during manufacture and packaging (i.e., prior to sale). As illustrated, the pouch member 112 of the device 110 is partially inverted as the device is being removed from the protrusion portion 102 of the mold. When the pouch is approximately one-half inverted, it has the appearance shown in Figure 13a. Then the pouch member is rolled upon itself toward the flange member, as illustrated in Figure 13B until it is completely removed from the protrusion 102 of the mold. For example, brushes may be used to roll the pouch in this manner. Figure 13c illustrates the entire brief with the pouch member completely rolled. The brief may be worn in this form until the time of intercourse; then the pouch will easily unroll and extend into the vagina to the position illustrated by dotted line 112A. Another embodiment of the present invention is illustrated in Figures 25 through 27. They show an anatomically configured, hermaphroditic prophylactic device 120. The folded unit 120 includes a generally rectangularly configured shield portion 122 having a narrow central segment 124 and a pair of end wing segments 126, 128. The wing segments 126, 128 have a gradually tapering width which is bounded by a pair of segments 130, 132 of a continuously formed peripheral bead 134 which converge from a first end segment 133. A like pair of bead segments 136, 138 formed on the sides of the wing portion 126 converge from a second end segment 135 of the peripheral bead 134. Segments 136, 138 are joined to central bead segments 140, 142 that are located in spaced parallelism. They are joined respectively to the inwardly convergent bead segments 130, 132. The prophylactic device 120 further includes an integrally formed pouch 144 that is centered in the center region 124 of the shield portion 122. The pouch 54 has an entrance opening 145. The pouch portion includes an end closure 146 that is joined to a rolled ring 148 that is formed during a manufacturing process to be described. The rolled ring 148 and the end closure 146 are located on the inner surface 150 of the prophylactic device 120. More particularly, the inner surface 150 has a length from the extreme ends of the wing portions 126, 128 and a width at the center region 124 to anatomically fit the user to provide complete coverage of the perineum regions of a user to prevent bodily fluids from contacting such regions during use of the prophylactic device 120. As shown in Figure 26, the rolled ring 148 has a prepackaged position 148a, a piloting position 148b and a fully extended position 148c (Figure 15d). More specifically, in the illustrated arrangement, the shield portion 122 has a length L in the order of 22 cm. The maximum width WM of the wing portions 126, 128 is in the order of 12 cm and the center region 124 has a width W of 9.5 cm and a height H of 6 cm. The wall thicknesses of the shield portion 122 and of the pouch 144 can be selected from the ranges discussed with respect to the embodiment of Figures 1 and 2 and the other various embodiments. The aforesaid dimensions are configured to anatomically relate to the perineum region wherein the pouch 144 can be rolled from its stored position in close spaced parallelism with the plane of the shield 122 to an extended position within a body cavity of a user. One aspect of the present invention is that the rolled ring portion 148 is configured so that the pouch 144 will unroll to form a single wall piloting segment 152 shown in dotted line configuration in Figure 26 upon first entry into the body cavity. The piloting segment 152 will be carried by further entry into a body cavity by unrolling the rolled ring segment 148 from the shield portion 122 until the pouch 144 is fully disposed as depicted at 155 within the body cavity (Figure 15d). One use representation of the prophylactic device 122 of the embodiments 25 through 27 is somewhat diagrammatically illustrated in Figure 14. In this representation, the prophylactic device 120 is secured to a strap system 154 that includes an elastic waist segment 154a. The strap system 154 includes a pair of straps 156, 158. Each strap 156, 158 has fastener means 159 secured to corner segments 126a and 126b of the wing portion 126. The strap system 154 further includes a pair of front located long straps 160, 162 that are connected at one end to the waist segment 154a and at the opposite end thereof to corner segments 128a, 128b of the wing portion 128. As shown in Figure 15, the rolled ring 148 is located out of bodily contact with the user so as to permit comfortable wear of the prophylactic device 120 prior to use. Upon use, the inside and outside of the closure wall 146 can be suitably lubricated. Initial penetration into the body cavity represented by the anal passageway 166 causes the piloting segment 152 to separate from the rolled ring 148 to form a piloted entrance and release of the pouch 144 into the anal canal 166. The pouch 144 is completely unrolled as shown in Figure 15b upon further penetration of the anal canal 166 so as to dispose the inner surface 150 of the prophylactic device 120 in full shielding relationship with the perineum 170 during use. The full shielding relationship extends side to side of the perineum region 170. In accordance with the present invention, the extent of the shielding by the anatomically configured prophylactic device 120 is selected to provide desired full coverage of a perineum region 170 of a user without contacting extensive portions of the exterior body surface of the user in a manner which could cause discomfort. Nevertheless, the extent of the anatomic dimensions of the shield portion 122 are able to cover the aforedescribed perineum region 170 to prevent the exchange of bodily fluids between the user of the prophylactic device and a person penetrating and extending the pouch 144 of the device, thereby to provide desired protection during use of the prophylactic device 120. A further feature of the present invention is that the strap system 154 is readily connected to and disconnected from a prophylactic device 120 prior to and following use so as to enable the prophylactic device 120 to be removed from the anal channel (or other body cavity) following use without an exchange of the bodily fluids to a person handling the pouch. More specifically, in order to assure such separation, the connections at each of the corner portions 122a, 122b, 128a, 128b is by use of a simple snap configuration including a male snap portion 172 that is secured to the end of the strap system 154 and a female snap portion 174 on a split segment 176 of each of the straps as shown on the strap 160 at the corner 128a in Figure 14. The arrangement enables the user to remove the strap system 154 and attached prophylactic device 120 from the user. The inside shielded portion of the surface 150 can then be grasped at the split strap segment 174 to unfasten the strap ends from the used prophylactic device 120. The system enables the prophylactic device 120 to be removed following use without unnecessary hand contact with bodily fluids on the outer surface 178 thereof. Most bodily fluids shielded by the prophylactic device 120 are concentrated within the interior cavity 180 of the extended pouch, which is shown at 182 in Figure 15b. The anatomically configured condom 120 shown in Figures 25 through 27 is shown on a female person in Figure 16. In this embodiment, the prophylactic device 120 is representatively shown as being connected to a bikini-like panty garment having an elastic waist portion 184 with a buttocks engaging back panel 186 and a shallow frontal segment 188. The back garment panel 186 is connected to the corner regions 128a, 128b of the wing segment 128 by male snap segments 190 on straps 192 to engage female snap components 194 secured to the corner of the rear panel 186 of the bikini-like garment. A like snap fastener assembly 196 connects the opposite corner of the rear panel 186 to the corner region 128a of the wing portion 128. The front segment 184a of the elastic waist carries a plurality of straps 198a, b, c, and d each having a male snap formed thereon which, as shown in Figure 16a includes a male fastener element 202 on the strap 198a which is pressed through the corner segment or an edge of the wing segment 126 to engage a female snap element 204 on the inner surface at the lower edge of the shallow frontal segment 188. The garment for carrying the prophylactic device 120 can also be in the form of a strap system as shown in Figure 14 in which case the small straps 156, 158 will be located on the front of a female and the back long straps 160, 162 will extend around the rear buttocks of a female user of the prophylactic device 120. In either case, the prophylactic device 120 is located so that the end closure 146 is disposed in covering relationship to the vulva 204 at the entrance to a vaginal canal 202 (Figure 15d). The inner surface 150 of the shield portion 122 is thus disposed in protective overlying juxtaposed relationship with the vulva 204 and also covers the perineum regions 208 of the user extending from the upper region of the pubic area to the perineum in the region of the anal orifice or canal of the female user. Thus, a substantial portion of the bodily surface of a female user is covered by the anatomically configured, hermaphroditic prophylactic device 120 without placing a substantial portion of an elastic or plastic like synthetic material against the outer surface of the user. Consequently, the device can be worn prior to use without discomfort. The initial position of the prophylactic device 120 is shown in Figure 15c at which point a portion of the exterior body surface of the female is covered by the contraceptive device 120 to protect against bodily fluid exchange during normal use. The prophylactic device 120 can be carried either on a strap system of the type shown in Figure 14 or on a bikini like garment. Prior to extension of the rolled pouch 144 the prophylactic device 120 is disposed in overlying relationship but out of engagement with the vulva 204 and other portions of the female person using the prophylactic device. The end closure 146, however, is positioned for ready disposition of the piloting segment 152 of the pouch 144 into the vaginal cavity 202 when a penis is inserted thereagainst to extend the pouch freely into the vaginal cavity 202. The length of the pouch 144 is greater than that of an erected penis and will have a dimension which is great enough to extend the pouch to form a loose fitting cover of the walls of the vaginal cavity 202 as shown in Figure 15C in diagrammatic form. One feature of the present invention is that a forwardly located wall segment 146a of the extended pouch is located in overlying relationship to the clitoral region of a female user. Stroking movement of the penis within the vaginal canal will occur without undue contact between the glans region of the penis and the walls of the extended pouch 155. The wall segment 146a is joined to the flat shield portion 122 at an exterior anchor point 122a thereof. The exterior anchor point 122a and the wall segment 146a are operative during insertion and withdrawal of a penis from the interior of the extensible pouch to produce a rolling of the wall section 146a for pleasurably stimulating the clitoral region during intercourse. Consequently, the prophylactic device 120 will not interfere with pleasurable use thereof during coitus. In accordance with other aspects of the present invention, the prophylactic device 120 of the present invention is formed by a process as set forth in Figures 18 through 20. The process includes a mold 220 having a flat surface 222 thereon of a planar extent corresponding to that of the planar extent of the shield portion 122 bounded by the bead 134. The bead 134 is initially disposed at a bead support ridge 126 around the periphery of the flat surface 122. The flat surface 222 has a protuberance 224 extending outwardly. The protuberance 224 has an outer surface 226 thereon dimensioned to correspond to that of the inside surface of the extended pouch 155. In practicing the invention, the mold 220 is connected to suitable carriage means for movement into an open ended container 228 that has a body of synthetic or latex material 230 therein of a composition as discussed in the earlier embodiments, which can be deposited on the surfaces 222, 226 to form a resultant thin layer deposit thereon. The deposit can be formed by a single or double dip process which includes directing the mold 220 along a path 232 into the body of material 230 to form a layer of material on the surface 226. When the mold 220 is located in the dotted line position shown in Figure 18, it can be tilted about an arc 235 so as to deposit a thin layer of material across the surface 222. The resultant deposited material is shown in Figure 19. The deposited material is stripped from the mold 222 by relative movement between the formed shield portion 122 and the flat surface 222 of the mold 220 whereby the shield portion 122 assumes the dotted line position shown by reference numeral 236 in Figure 19. This causes the pouch portion of the prophylactic device to be telescoped upon itself to form a double wall telescoped segment 238. The double walled telescope segment 238 is then engaged by suitable means such as rollers 240 to roll the telescoped double wall portion 238 upon itself from a return bend portion 242. The resultant rolled ring 148 has an outer wall segment 148d which will unroll as the ring 148 assumes its piloting position 148b. It has an inner wall segment 148e which will unroll after the pilot portion 152 is positioned. This rolled ring 148, as previously discussed, disposes the end closure 146 of the prophylactic device in close spaced parallelism with the bead 134 which has latex formed therearound to form the perimeter of the prophylactic device 120. The rolling of the ring 148 will remove the prophylactic device 120 from the form 220. The removed prophylactic device 120 can then be readily manipulated for various forms of storage. For example, in Figures 22 through 24, the prophylactic device 120 removed from the mold 220 can be folded end to end and then rolled from a joined end portion 240 to form a tubular configuration shown at 250 in Figure 24. The tubular configuration is readily insertable into the interior of an elongated container 260 which is representatively shown as having a cap closure 262. In this arrangement, each of the individual prophylactic devices 120 are packaged separately from the garment or strap systems for connecting the prophylactic device 120. As previously discussed, the prophylactic device is anatomically configured to extend over the perineum regions of the user to shield such regions from bodily fluids during use. The prophylactic device 120, as stripped from the mold 220, is also readily foldable as shown in Figure 25 to form a first joined end region 256 which can be folded on itself to form a second folded end region 258 that can be made even more compact by folding back upon itself to form a third fold region 260 thereby to define an eight layered compact condom package 262 that is readily adapted for packaging in compact, flat container configurations representatively shown at 264 in Figure 22c.
