A V shaped spring can be provided to shape an end extension to form the open end of the condom (10). The retention sponge (28) can be sealed within the exteriorly accessible pocket by a removable cover that seals the sponge within the exteriorly accessible pocket while in its pre-deployment position. The locking and sealing member is removable from the telescoped pouch portion for deployment.

Description: FEMALE CONDOM FIELD OF THE INVENTION This invention relates to prophylactic devices and more particularly to female condoms having a pouch portion insertable into a deployed position. This application is a continuation-in-part of 08/853,030 filed May 8, 1997 that is a continuation-in-part of provisional application 60/035,546 filed December 31, 1996. BACKGROUND OF THE INVENTION With the widespread prevalence of venereal disease and the growing occurrence of AIDS (acquired immune deficiency syndrome), there is an increasing need for effective means to prevent the transmission of such diseases through sexual contact and resultant exchange of bodily fluids between a user and the user's partner. Heretofore, conventional means for preventing the transmission of such bodily fluids and exposure to such diseases because of bodily contact have included the use of condoms, jells, creams and the like. Additionally, there have been proposals to provide female prophylactic devices, which can be worn by a female prior to use and disposed of following use. While such conventional and proposed devices are suitable for their intended purpose, it has been found that they are not totally effective for various reasons. One example of a prior prophylactic device for use by females is that set forth in U.S. Pat. No. 3,536,066. The '066 patent shows a pant styled garment having a bellow configured pouch thereon which is located on the exterior of the pant. The bellows is preinsertable into the vaginal canal of a female prior to use. After the bellows is inserted, convolutions therein are extended to provide for extension of the bellows to accommodate an erected penis during use of the contraceptive device. The device requires preinsertion of a segment of the bellows and does not include means for piloting a large pouchlike member into a vaginal canal or means for holding such a member in place. Furthermore, the garment portions of the device are formed from rubber material which is configured to contact a large portion of the waist region of the user as well as the buttocks and hip regions of a user so as to cause possible irritation and discomfort when worn for substantial periods of time prior to use. U.S. Pat. Des. No. 254,809 to Meldahl discloses a device for use as a male contraceptive. While the contraceptive has a larger diameter than typical condoms, it does not include a portion thereon which will serve as the device to prevent the passage of bodily fluids between a user and a partner. There are not straps to hold the device in place. Swiss Patentschrift No. 117,234 (1925) discloses a female contraceptive device having a pouch that includes a generally circular collar on the other end thereof. There is no suggestion to provide a portion of the device that will cover and conform to the full perineum region of a user. Furthermore, there is no suggestion of how to hold the device in place during use. Furthermore, the outer lip or collar of the condom can enter the vagina during intercourse so as to cause undesirable exposure of the users to the other's bodily fluids. U.S. Pat. No. 4,735,621 likewise shows a thin walled, condomlike, tubular protective device for insertion into a vaginal canal. It includes a resilient ring on one end thereof to anchor the device in the vaginal canal. The retention ring of the '621 patent is an integral part of the condom which requires special manufacturing tooling. Furthermore, the retention ring is configured to have a diameter corresponding to that of the pouch and a cross-sectional diameter that is small compared to the diameter of the ring. As a consequence the ring requires careful placement within the vagina so as to assure that it will fit in an interference relationship therewith to prevent the pouch from being withdrawn during coitus. Furthermore, the '621 retention ring may be oriented in a direction that will produce undesirable contact with an erected penis, i.e., causing pain during intercourse. Furthermore, the outer ring goes into the vagina during intercourse causing undesirable exposure of the users to bodily fluids. Other female condoms have been proposed that include an internally located resilient insert element for holding the pouch portion of the female condom in place. One example is set forth in PCT International Publication No. W090/00038 wherein an insert can be directed into the closed end of the pouch portion of the female condom. In this application, the insert is an absorbent and flexible expanded plastic material that includes spermicides or antiviral agents. The female condom in this case requires the use of a special insert and an applicator for performing the deployment of the female condom into its deployed position within a user. Another example of a female condom having an interiorly located retainer element is set forth in U.S. Pat. No. 5,325,871 that discloses the use of an insertable retention member that can be compressed during insertion and that will, following deployment of the female condom into its deployed position, serve both as a radially outwardly directed retention pressure device as well as a device for dispensing spermicides, fungicides or the like. While suitable for their intended purposes, such aforesaid devices have been found to lack an ease of application that will make the female condom acceptable and convenient to most users. A counterpart to PCT No. WO/00038 is United States Patent No. 5,193,555. As shown in Figure 1 this invention requires use of an insertion tool 15. Another female condom requiring an insertion tool is shown in United States Patent No. 5,146,930. In the '555 patent retention is provided by a multi-fingered insert with a central portion and a radially outwardly directed portion that springs out following tool insertion for holding the condom pouch in place. In the '930 patent retention is provided by a series of flexible protrusions that are on the outside of the pouch and that are inclined in a direction to prevent pull-out of the pouch. In both the '555 and '930 patent the pouch is connected to a shield that is arranged around the opening to the pouch and the pouch opening is located generally centrally of a thicker shield having an enlarged portion that holds the pouch opening centered while covering the entrance to the vagina. While such condoms provide protection and cover the perineum of a user they are difficult to insert into the user and are uncomfortable if kept in place during walking and the like since the outer thicker shield is continuously spread open to keep the pouch opening centered with respect to the shield surface. All of the above condoms reduce pleasure to one or both partners during intercourse. Accordingly, another feature of the present invention is to provide an easily inserted female condom that includes a pouch that has an extension thereon having the same wall thickness as the pouch and is configured to laterally collapse and expand freely to accommodate user movements. The arrangement does not require a separate thicker shield member arranged in a spread position to center the pouch opening with respect to the shield. In the embodiment of Figure 1, the shield portion is formed of the same wall thickness as that of the pouch and is arranged to easily collapse laterally. As a consequence, once inserted in place, the shield will, because of a thin wall having a thickness range of .02 mm to .06 mm, will enable the front and rear walls to easily move laterally to accommodate user movement. Still another problem with female condoms is the fact that they can interfere with pleasurable coitus. Thus, in accordance with another aspect of the invention sponge fillers are provided on the pouch on either side thereof closely adjacent the shield for filling any gaps between the vaginal wall and to form a tight opening for penal insertion in the vicinity of the clitoris for providing stimulation to both male and female users of the female condom. Still another problem with female condoms is that of accidental withdrawal and leakage from the female condom. Thus, in accordance with still another aspect of the present invention, a second premolded thin member is heat sealed to a shield on the open end of the female condom to provide a labyrinth seal against leakage from the interior of the female condom and to provide a directional guide into the interior of the female condom while providing an extension on the end of the female condom that will deploy automatically to prevent inadvertent withdrawal. SUMMARY OF THE PRESENT INVENTION In the present invention, a female condom has a pouch with a predeployment and a deployment position with respect to the inner and outer surface of a shield portion that enables the pouch of the female condom to be initially placed on a user such that the shield portion will cover the perineum region of the user. A retention sponge is located within an exteriorly accessible pocket of the pouch and the exteriorly accessible pocket and is held in place therein by member that is bonded to the inner surface of the pouch adjacent its closed end; the retention member holds the sponge in its predeployment position in a telescoped part of the pouch that is accessible from the exterior of the female condom to provide for insertion of the sponge and unfolding of the pouch into a fully interiorly located deployed position in which the sponge will force against the inner surface of the pouch adjacent its closed end to hold the closed end against the vagina walls and thus hold the pouch fully extended within the vagina in its deployed position. In another aspect of the invention, the shield is an extension on the open end of the pouch that is of the same wall thickness as the pouch and is open on at least part of its periphery to provide lateral flexibility that will adjustably conform the shape of the shield to the perineum attached to a V shaped rim with anterior, posterior angle and has the characteristics of a spring mechanism when the female condom is in its deployed position for providing greater comfort on the user during walking, sitting and other changes in user position. A still feature of the invention is to provide such a V shaped rim that has a flexible V member connected to the shield by rolling a portion of the shield around the V member. In another aspect of the present invention, a female condom has a pouch with a predeployment and a deployment position with respect to the inner and outer surface of a shield portion that enables the pouch of the female condom to be initially placed on a user such that the shield portion will cover the perineum region of the user. The pouch includes a dome shaped portion defining the closed end thereof. A retention sponge is located within the dome shaped portion; the dome shaped portion is joined to a telescoped segment of the pouch prior to deployment; the sponge in its predeployment position is accessible from the exterior of the female condom to provide for insertion of the sponge and unfolding of the telescoped segment of the pouch into a fully interiorly located deployed position in which the sponge is shaped by the dome shaped portion to force the closed end against the vagina walls and thus hold the pouch fully extended within the vagina in its deployed position. In accordance with another aspect of the present invention, the pouch of the female condom of the present invention includes a retention strap bonded to the inside surface of the pouch adjacent its closed end into which the sponge is located during initial assembly and thereafter located with respect to telescoped outer wall portions of the pouch that forms the exteriorly accessible pocket therein. The retention strap also covers the sponge so that the glans penis will not rub against the sponge in a manner that can cause irritation. In another aspect of the invention the retention sponge and telescoped pouch is covered by a locking and sealing member when the telescoped pouch is in its predeployment position. The locking and sealing member will prevent lubricant in the telescoped pouch from leaking out into the outer package and also keeping the lubricant in its original position during intercourse so that there will be enough lubricant for bother partners during intercourse. The locking and sealing member is configured to be easily removable from the exteriorly accessible pocket and the user thereafter is able to insert the pouch, along with the sponge, into a fully deployed position within the user in a manner that will prevent easy pull-out of the pouch from the deployed position. In one embodiment of the invention, the exteriorly accessible pocket is sealed by a locking and sealing member having a cover that is removably connected to the pouch. The cover can include a ring, patch or sleeve configuration or equivalents thereof as long as the exteriorly accessible pocket is completely closed by the locking and sealing member when in place on the pouch. In all embodiments of the type including a locking and sealing member, the locking and sealing member is located on the outer surface of the shield portion so as to be readily removable from the female condom when the shield portion is securely in place over the perineum. The telescoped outer wall portions of the pouch that form the exteriorly accessible pocket are positioned for insertion into a deployed position wherein the sponge is concurrently placed, with the closed end of the female condom, into a fully deployed position within the user such that it will be securely connected against pull-out during intercourse. Accordingly, one feature of the present invention is to provide a female condom having a pouch thereon with a rolled up predeployment position on the outer surface portion of a shield portion; the pouch also having a deployed position on the inner surface portion thereof; the pouch including telescoped outer wall portions in its predeployment position defining an exteriorly accessible pocket having a retention sponge therein. Another feature of the present invention is a locking and sealing member that covers the exteriorly accessible pocket for controlling fluid leakage into an outer package; the locking and sealing member including a segment connected to the pouch adjacent the open end thereof for locking the telescoped outer wall portions in a predeployment position and wherein the locking and sealing member is easily removable for enabling the pouch to be place in its deployed position. A further characterization of the invention is that the retention sponge is located within a telescoped pocket that is covered in part by a cover that is removably connected to the pouch of the female condom. Still another characterization of the present invention is that the locking and sealing member includes an opening therein through which the shield portion of the female condom extends outwardly from the pouch for clamping the shield portion prior to deployment. Still another object of the present invention is to provide a locking and sealing member cover in the form of a ring having an opening therein through which the shield portion extends into overlying relationship with the perineum of a user prior to deployment of the female condom into its deployed position. Still another object is to provide such a locking and sealing member in the form of a ring that includes first and second ends that are joined together adjacent the outer surface of the shield portion and in proximity of the open end of the pouch of a female condom. Still another object of the present invention is to further seal a locking and sealing member having such an opening therein by the provision of foldable sides on the locking and sealing member that are positionable following insertion of the shield portion through the locking and sealing member to overlie the opening to prevent leaking therethrough into the interior of the locking and sealing member. Yet another characterization of the present invention is that it can include a strap portion across the width of the closed end of the pouch for insertion of a resilient retention sponge prior to forming telescoped outer wall portions on the pouch having an exteriorly accessible pocket that is sealed. Yet another characterization of the present invention is that it can include a strap portion formed as a closed pouch across the width of the closed end of the pouch for insertion of a resilient retention sponge prior to forming telescoped outer wall portions on the pouch having an exteriorly accessible pocket. Yet another characterization of the present invention is that it can include a strap portion formed as a pouch having laterally opened ends and extending across the width of the closed end of the pouch for insertion of a resilient retention sponge prior to forming telescoped outer wall portions on the pouch having an exteriorly accessible pocket. Still another feature of the present invention is the provision of sponge members therein serving as cavity fillers adj cent the shield portion of the female condom. Yet another feature of the present invention is the provision of an extendable shield on the entrance end of a female condom for protecting against leakage from the interior of a pouch and for protecting against inadvertent withdrawal during coitus. Yet another feature of the present invention is to incorporate a semi-hard piece of material in or over the pouch near the clitoris in deployment position for stimulation of the clitoris during intercourse.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS OF THE PRESENT INVENTION Referring now to Figure 1, a female condom 10 is shown in a predeployment position on a user. The female condom 10 has a pouch 12 with a closed end 14 and an open end 16. A tubular outer wall 17 joins the closed end 14 with the open end 16. A shield portion 18 has an inner surface 20 and an outer surface 22 and comprises a front panel 21 and a rear panel 23 for covering the perineum region of a user. The shield portion 18 is joined to string type waistband 24 that is made of a suitable resilient material and is configured to fit on the hips of a user. In accordance with one aspect of the present invention, the pouch 12 is preconfigured to have a rolled up predeployment position shown at 24 in Figures 1 and 3. The predeployment position locates the pouch on the outer surface 22 of the front panel 21 in a position that will enable the female condom to be easily positioned on the user by steps to be disclosed, while retaining the pouch portion in a location for easy deployment from a predeployment position into a deployed position within the vaginal tract of a user. More specifically, as shown in Figure 5, to accomplish this objective, the pouch 12 has a sponge retention strap 26 thereon connected across the width of the closed end 14 thereof. The strap 26 has a semicircular configuration and is two walled at 26a, 26b to form an umbrella like cover as shown in Figure 6 to enclose the outer surface of a resilient retention sponge 28 between the end 14 and the strap 26. The strap 26 thus covers the sponge 28 during use so that there is no direct contact between a penis and the sponge and will prevent lubrication in the pouch being absorbed by the sponge. In accordance with the present invention, the sponge member and pouch 12 are located in a predeployment position on the outer surface 22 of the front panel 21 of the shield portion 18 to be readily accessible to a user for deployment as will be described. In the predeployment position, the tubular outer wall 17 has a telescoped portion 30 formed by wall segments 32 and 34 of the pouch 12. The wall segment 32 extends from the closed end 14 and is connected to the wall segment 34 by a rolled segment 36. Together the telescoped portion 30 forms an exteriorly accessible pocket 38. Once formed to have the telescoped portion 30, the pouch 12 is sealed by a locking and sealing member 40 best shown in Figures 1 and 3. In this embodiment, the locking and sealing member 40 has a ring configuration with opposite ends 42, 44 thereon that are secured together. An opening 46 in the locking and sealing member 40 is arranged so that the front and rear panels 21, 23 are easily positioned on a user as shown in Figure 1. Further, the locking and sealing member 40 locates the sponge 28 in a sealed relationship on the front of the user in a predeployment position that is. easily accessible for positioning in a deployed location. More specifically, the inner surface 48 of the locking and sealing member 40 will cover and seal the exteriorly accessible pocket 38 as best shown in Figure 3. The rolled segment 36 is folded upon itself and the locking and sealing member 40 will control leakage of fluid that might be present within the sponge member 28 prior to deployment. As shown in Figures 14A-14D, the embodiment of the invention shown in Figures 1-4, the female condom 10 is gently unfolded from a package and hands of the user are placed in the waistband 24 so that it can be expanded while the palms of the hands face inwardly. This stretches the waistband 24 so that it is easy to step into the female condom (Figure 14B). In this embodiment, the locking and sealing member 40 is positioned at a point where it can be removed easily at a notch 42a therein that captures both sides of the front panel 21 where it exits the opening 46. The locking and sealing member 40 is thus easily torn from the female condom such that the exteriorly accessible pocket 38 of the telescope portion 26 is open (Figure 14C). Thereafter, the pouch 12 can be inserted into a deployed position (Figure 14D) along with sponge 28 deeply into the user so that the sponge 28, when expanded, will prevent pullout of the pouch during intercourse. While a split ring member 40 is shown, a continuous ring with an opening 46 also would serve as a locking and sealing member. In the embodiments of Figures 8 and 9, a locking and sealing member 48 includes a cover 50 that overlies the folded, rolled segment 36 of the pouch 12, as best shown in Figure 9. The cover 50 has a patch configuration and includes a suitable adhesive 52 on the interior surface thereof that will hold the rolled segment 36 closed when the female condom is in its deployed position. The cover 50 is locked in place by a string 53 that ties around the front panel 21 and is easily removed for providing access to the exteriorly accessible pocket 30. Thereafter, the female condom of this embodiment is deployed in the same fashion as set forth above. In a still further embodiment of the invention shown in Figures 10 and 11, a locking and sealing member 54 includes a cover 55 formed as a sock that fits over the rolled segment 36. In this embodiment, the cover 55 has a press fit sealing relationship with the pouch or it can include adhesive segments 56 thereon for securing the cover 55 in a sealed relationship with respect to the pouch when in its predeployment position. If desired, tie strings 58 are secured to cover 55 to lock the cover 55 in place on the shield. In still another embodiment of the present invention shown in Figures 12 and 13, if desired, the opening 46 provided in the embodiment of Figures 3 and 4 can be further sealed by providing a locking and sealing member 60 having foldable sides 62, 64 thereon that are on either side of an interior panel 66 having an opening 46' formed therein corresponding to the opening 46 in the embodiment of Figures 1-4. In this embodiment, after the shield portion has been pulled through the locking and sealing member 60, the foldable edges 62, 64 are folded over into an overlapping relationship shown in Figure 13 at broken line 66 that will cover the opening 46' to prevent leakage of fluid from the sponge when in its predeployment position. In the embodiment of the invention shown in Figures 15 and 16, a female condom 70 is illustrated that includes a pouch 72 with an extension 74, having the same wall thickness as the pouch, e.g., for most materials in the range of .02 mm to .06 mm. The front extension 74 extensions has a triangular configuration of inverted isosceles shape with an apex 74a and a pair of wing segments 74b, 74c conformed to the general shape of the pelvic bone region and having a surface area that will cover the perineum of a user. The front extension 74 has the same wall thickness as pouch 72 throughout the planar extent of the surface area thereof for allowing unrestricted lateral contraction and expansion to accommodate body movement of the user. The extension 74 defines an opening 75 to the pouch interior and the opening 75 extends from the apex 74a of the inverted isosceles shape to the pair of wing segments 74b, 74c. The retention sponge in this embodiment is shaped as a half moon sponge 76 connected by a strap 77 to the tip of a closed end 78 of the pouch 72. In this embodiment, the strap 76 is formed as a ring 80 having open sides 80a, 80b through which side portions 76a, 76b of the half moon shaped sponge extend. Antibiotics or spermicides can be added if desired. The half moon and ring type connection is applicable for use in the previously described embodiments, with it being understood that in such case the sponge would replace that shown in the first embodiment and the ring would replace the sponge retention pocket. The half moon shaped sponge 76 and ring connector 77 are shown in Figure 21 prior to being placed in a telescoped predeployment position. The sponge 76 is shown in perspective in Figure 22 as constituting one half of a circular disc that has a base 76c; side surfaces 76d and 76e; and a curved top 76f that has the side portions 76a, 76b at opposite ends thereof. As in the prior embodiments, prior to deployment, the pouch 72 is telescoped as shown at 82 in Figure 18. In the predeployment position, the pouch 72 is located in front of the user and is held in place by two front straps 84, 86 and a rear strap 88 all joined at their distal ends by a waist band 90. Reinforcing strips 90a and 90b can be provided at the points of connection of straps to the extension 74. All the prior embodiments have a locking and sealing member that will locate the sponge in a sealed relationship to the user in predeployment position. The locking and sealing mechanism will stop the spread of lubricant and keep the sponge in position, in a telescoped pouch. If desired, the condom shown in the embodiments can be placed in a lubricated or spemicide containing package for providing desired lubrication when in use. Referring now more specifically to the embodiment in Figures 18-20, the straps are omitted and a condom 84 when deployed is configured so that in itself will provide a self supporting adaptive configuration for covering the perineum without hindering lateral shifting movements of a user that will close and open the entrance to a pouch 86. More particularly, in this embodiment only a front extension 91 is provided. As in the embodiment of Figures 15-16, in this embodiment the front extension 91 has a triangular configuration of inverted isosceles shape with an apex 93 and a pair of wing segments 92, 94 conformed to the general shape of the pelvis region and having a surface area that will cover the perineum of a user. The front extension 91 has the same wall thickness as pouch 84 throughout the planar extent of the surface area thereof for allowing unrestricted lateral contraction and expansion to accommodate body movement of the user. Suitable wall thicknesses for most materials is in the range of .02 mm to .06 mm. The front extension defines an entrance 95 to the pouch formed between the two wing segments 92, 94. The wing segments 92, 94 are joined at the apex 93 and have free edges 92a, 94a thereon that are at a point spaced from the apex 93. Thus, when deployed the wing segments 92, 94 are integral extensions of the wall of the pouch 72 and define the entrance opening 95 to the pouch 72 that extends all the way to the apex 93 for ease of entry and for imparting unrestricted lateral movement to accommodate user movement. The entrance opening 95, itself is open at the top at a location that will be above the entrance to the pouch. The use of integrally formed single wall thickness extensions on the pouch with free edges provides lateral freedom as in the case of the first embodiment in which the frontal shield is a single wall extension of the pouch. A feature of the condom is the provision of a V-shaped spring member 100 that partially surrounds the wing portions 92, 94. In the broad aspect of the invention, the spring member is selected with an angle from anterior to posterior and side to side of user in order to conform to the perineal area of the user, in different positions, like walking, standing, sitting, prone position, etc. More specifically, the V shaped spring member 100 includes an apex 102 that is located at the apex 93. Spaced outwardly diverging spring segments 104, 106 are joined at the apex 102. They each have a distal end 104a, 106a that extends to the wing edges 94a, 96a. The spring segments 104, 106 are lightly biased apart from one another to spread the wing portions 94, 96 to cover the perineum when the pouch 72 is in its deployed position. Since the wings are open at the edges 94a, 96a they will readily move laterally so that the spring segments can be moved toward one another if the user were to be seated following deployment of the condom. Such unrestricted configuration also enables the spring segments 104, 106 to be moved with respect to the apex 102 during use such that the distal ends 104a, 106a can almost close as shown in broken outline in Figure 20 or can be fully separated to the width of the extended edges 94a, 96a as shown in solid line in Figure 21. Such lateral contraction and extension provides adjustment of the shape of the extension 91 to the user during a wide range of movements, e.g., walking, sitting, stretching so that deployment of the condom will not be an undesirable distraction. Additionally, as best shown in the side elevational view of Figure 19, the spring segments 104, 106 each are bowed outwardly from the user such that inward pulling action will be absorbed by flattening of the spring segments 104, 106 as shown in dotted line at 108 in Figure 19. Such action provides improved conformation to the perineum of a user since the spring segments 104, 106 are able to flex into the adjacent shape of a user in the vicinity of the pelvic bone while remaining free to laterally shift toward and apart from one another about the apex 102 that serves as a pivot point for lateral movement of the distal ends of the spring segments 104, 106. The V-shaped spring design of Figures 18-20 will not contain a locking and sealing member because this design is packaged without any rolling. Also, in this design, the pouch will be telescoped. The telescope will contain a pocket in the front and a pocket in the back. Lubrication will be instilled in the pockets. In still another embodiment of the invention shown in Figure 23, a female condom 110 is shown having a pouch 112 with an entrance 114 and a closed end 116. In this embodiment the entrance has a double wing configuration on the material that extends from the pouch and has the same frontal appearance as the material forming the entrance to the condom shown in Figures 15-19. In this embodiment the V-shaped spring 102 is omitted and it is replaced by a preformed layer cover 120 with a shape conformed to the double wing surface 118. The preformed layer can be formed of a suitable thermoplastic material that can be vacuum formed or otherwise molded into a shape that will include an inner surface 122 that generally conforms to the perineum of a user at the pelvis bone and that will flex to conform thereto. Additionally, the cover 120 forms a two layer entrance having a space 124 therebetween that defines a labyrinth seal for preventing leakage from interiorly of the pouch to the exterior of the two layer entrance. A further feature is that the cover 120 includes an opening 126 generally aligned with the interior of the pouch and adapted to form a pilot opening for directing an erect penis through the two layer entrance into the interior of the pouch. The cover 120 further will be freely moveable outwardly of the wing surface 118 material to provide an extension on the end of the pouch to prevent inadvertent withdrawal during coitus. The cover 120 is shown in solid line two layer piloting configuration in Figure 23 and is shown in an extension position at dotted line position 120a in Figure 23. A retention sponge 128 is provided that can have either the open, ring type connection strap or can have a closed pocket type strap for holding it on the inside end surface of the pouch 112. In the embodiment of the invention shown in Figures 25-27 a pair of additional sponge like members cavity filler members 130 and 132 are connected to a pouch 133 spaced from an entrance extension 134 like those previously described. Each of the filler members 130, 132 is made of sponge like material as in the previous sponge elements. They are each located in pockets 135 formed on the outside of the pouch 133 on either side thereof. The retention sponge on the closed end of the pouch can be eliminated. The cavity filler members have a thickness at their center of about one to one and one-half cm. They taper in the direction of the closed end to about a thickness of one- half cm. The members 130, 132 are provided to fill the inside of vaginal cavity that has been extended because of childbirth or the like. The members 130, 132 are located so as to fill the anterior one-third of the vagina cavity and cause tightness around the glans penis. Consequently, the female condom is configured to provide sexual stimulation concurrently to both female and male members. In the embodiment shown in Figure 28, an elevated, semi-hard patch 100 is incorporated on the pouch 99 near the open end, at the upper surface thereof, in order to cause stimulation of the clitoris during intercourse. In the embodiment shown in Figure 29, the outer most portion of the open end of the pouch near the rim 102 is provided with two adhesive bands 103, 104 to be applied to the abdomen after deployment of the condom to prevent drooping of the rim. In the embodiment of the invention shown in Figures 30-36, a female condom 140 is illustrated that includes a pouch 142 with an entrance extension 144, having the same wall thickness as the pouch, e.g., for most materials in the range of .02 mm to .06 mm. The entrance extension 144 has a triangular configuration of inverted isosceles shape with an apex 144a and a pair of wing segments 144b, 144c conformed to the general shape of the pelvic bone region and having a surface area that will cover the perineum of a user. The entrance extension 144 has the same wall thickness as pouch 142 throughout the planar extent of the surface area thereof for allowing unrestricted lateral contraction and expansion to accommodate body movement of the user. The extension 144 defines an opening 145 to the pouch interior and the opening 145 extends from the apex 144a of the inverted isosceles shape to the pair of wing segments 144b, 144c. In this embodiment the pouch 142 includes a dome shaped portion 146 defining the closed end of the pouch and provided to shape a retention sponge 148. The retention sponge 148 in this embodiment is shaped as a cylindrical member having a diameter greater than that of the dome shaped portion 146 such that the dome shaped portion 146 will shape the sponge 148 to have a curved form for ease of insertion as will be discussed. The curved form is defined by the end surface 150 of the pouch as best shown in Figures 32 and 34. The retention sponge 148 is shown in perspective in Figure 31 as constituting a circular disc that has a base surface 148a; a top surface 148b and a peripheral surface 148c. While a cylindrical shape is shown, other shapes such as spheres; half spheres or shapes of other geometry can be used so long as they will be conformed to form a radially outwardly directed projection in the pouch from a pouch segment 143 formed of a lesser diameter between the dome shaped portion 146 and the entrance extension 144. The retention sponge 148 and dome shaped portion 146 are shown in Figures 33, 34 and 36 in a telescoped predeployment position. As in the prior embodiments, prior to deployment, the pouch 142 is telescoped as shown at 152 in Figure 36. In the predeployment position, the pouch 142 is located in front of the user and is held so that the surface 150 is ready for insertion into the vagina. Thus, the condom 140 like in the embodiment of Figures 16-18 will provide a self supporting adaptive configuration for covering the perineum without hindering lateral shifting movements of a user that will close and open the entrance to pouch 142. More particularly, in this embodiment front extension 144 has a triangular configuration formed by a shaped hollow member 154 so that the extension 144 will conform to the general shape of the pelvis region and having a surface area that will cover the perineum of a user. The hollow member 154 is a plastic straw shaped to have wing segments 156, 158 joined at an apex 160. The wing segments 156, 158 have free ends 156a, 158a thereon that are spaced from the apex 160. The hollow member is formed as a V-shape to spread the extension 144 defining the opening 145 to the pouch interior and the opening 145 extends from the apex 144a of the inverted isosceles shape to the pair of wing segments 144b, 144c. In one aspect of the invention the marginal edge 144d of the extension 144 is rolled around the hollow member 154 as best seen in Figure 35 to form a connection 162 therebetween. If desired further adherence of the extension 144 to the hollow member 154 can be provided by a suitable layer of adhesive material. The hollow member has spring action due to the fact that it is shaped from a suitable plastic material having an elasticity at the apex 160 and in an angle from anterior to posterior and side to side of user in order to conform to the perineal area of the user, in different positions, like walking, standing, sitting, prone position, etc. More specifically, the segments 156, 158 are lightly biased apart from one another to spread the wing segments 144b, 144c to cover the perineum when the pouch 72 is in its deployed position. Since the wings are open at an edge 144d between free ends 156a, 158a they will readily move laterally so that the spring segments can be moved toward one another if the user were to be seated following deployment of the condom. Such unrestricted configuration enables the segments 156, 158 to be moved with respect to the apex 160 during use such that the ends 156a, 168a can almost close or can be fully separated to full width as shown in Figures 33 and 34. Such lateral contraction and extension provides adjustment of the shape of the extension 144 to the user during a wide range of movements, e.g., walking, sitting, stretching so that deployment of the condom will not be an undesirable distraction. If desired, as in the previous embodiment of Figure 19 the hollow member 154 can have its segments 156, 158 bowed outwardly from the user such that inward pulling action will be absorbed by flattening as in the previously described embodiment. Such action provides improved conformation to the perineum of a user since the spring segments 156, 158 are able to flex into the adjacent shape of a user in the vicinity of the pelvic bone while remaining free to laterally shift toward and apart from one another about the apex 160 that serves as a pivot point for lateral movement of the distal ends of the spring segments 156, 158. The V-shaped spring design of Figures 30-36 contains no locking and sealing member because this design is packaged without any rolling. Also, in this design, the pouch will be telescoped at 163 as shown in Figure 36. The telescope will contain a pocket 164 in the front and a pocket 165 in the back. Lubrication can be provided in the pockets. The condom can be employed either by the fingers or by use of an applicator that is shown in broken line at 166 in Figure 36. As in the prior embodiments, antibiotics or spermicides can be added if desired. If desired, the condom shown in the embodiments can be placed in a lubricated or spemicide containing package for providing desired lubrication when in use. In the present invention, the female condom can be formed of material preferably made of elastic impermeable substances such as natural rubber (e.g., latex), synthetic rubber (e.g., silicone rubber), or polyurethane. Other useful materials include non-elastic substances such as various thermoplastic materials including polyethylene. The retention sponge shown in the various embodiments of the invention can be formed of a resilient, porous material such as natural sponge material or a suitable, soft, porous sponge-like natural or synthetic material having voids. Suitable materials include natural sponge material; soft rubber open lattice material; polyurethane foam of the open cell blown type and the like that can be compressed into a compact shape and that are resiliently expandable into a retention position when deployed. The voids can be impregnated with lubricant, spermicides, fungicides, bactericides or antiviral agents that can be slowly released therefrom to protect a user as desired. While the best mode for carrying out the invention has herein been described in detail, those familiar with the art to which this invention relates will recognize various alternative designs and embodiments for practicing the invention.
