       TECHNICAL FIELD 
       [0002]    The present invention relates to sexual stimulation devices, and more specifically to an erogenic stimulation device for men having a compact state for storage which expands to approximate a female pelvic region and buttocks when filled with warm water, the cooperation of warm water with interior and exterior elastomeric elements provides a more natural interior sensation, natural body temperature, and responsive dynamic motion. 
       BACKGROUND ART 
       [0003]    The disclosure of U.S. Provisional Application No. 61/529,906, filed Aug. 31, 2011, is hereby incorporated herein in its entirety by reference. 
         [0004]    Marital or sexual aids (commonly referred to as “sex toys”) have been known and used throughout the centuries by both men and women. Generally, sex toys for men are compact, relatively static, and merely provide an approximation of a vaginal tract and opening made of an elastomeric material, such as one of many types of rubber or similar material, sometimes with realistic external features, sometimes without. 
         [0005]    On drawback of these common devices is the attempt to approximate a correct feeling of tightness about the user&#39;s penis and develop friction between the simulated vaginal tract and the user&#39;s penis through a narrow vaginal tract and/or opening. However, a successful implementation of this approach requires custom sizing of the vaginal tract and/or opening to optimally suit the size of the individual user&#39;s penis. 
         [0006]    An undesirable attribute of these common devices the simulated vaginal tract is open at both ends, which when in use creates unnatural and distracting suction noises. In addition, it has been noted that these devices allow leakage of lubricant and/or seminal fluid through the open end. 
         [0007]    To provide physical stimulation, these devices are generally held in the user&#39;s hand(s) and moved back and forth along the length of the penis, or held stationary and the penis is moved in and out of the device, or a combination of both. The motions available to the user by these common devices are similar to those of manual self-stimulation. While there are some sex toys for men that provide an approximately life sized simulation of a woman&#39;s pelvic region, genitalia, and buttocks, these devices are relatively static, and are conspicuous when stored due to their size. 
         [0008]    Many of the know devices are unable to provide a natural body temperature thereby detracting from the experience. 
         [0009]    Thus, what is sought is an erogenic stimulation device for men, which overcomes one or more of the shortcomings and limitations, set forth above. 
       SUMMARY OF THE INVENTION 
       [0010]    What is disclosed is an erogenic stimulation device for men, which overcomes one or more of the shortcomings and limitations, set forth above. 
         [0011]    According to a preferred embodiment of the invention, an erogenic stimulation device for men has a compact state for inconspicuous storage when not in use and an enlarged state when filled with liquid such as warm water. The device includes an exterior element of an elastomeric material disposed about and containing an interior element of an elastomeric material. A cavity is defined between the elements which is associated with an opening of the exterior element. The interior element has an elongate overall shape and includes a first open end, a second open end, and a longitudinally extending passage extending therebetween. The first open end of the interior is disposed in the opening of the exterior element, and the second open end of the interior element is connected to and incorporated into the exterior element so as to be open and accessible through the exterior element to allow insertion of a penis into the passage. A closure element is closable about a portion of the exterior element adjacent to the opening and about the first open end of the interior element. The closure element sealably closes the opening to retain liquid in the cavity and hold the first open end in the closed opening. 
         [0012]    When a quantity of the liquid is retained in the cavity under pressure, the liquid exerts an external force against the interior element and an internal force against the exterior element, reducing the passage in size in at least one direction and expanding the exterior element from a compact state to an enlarged state. 
         [0013]    When the quantity of the liquid is removed from the cavity, the forces against the interior and exterior elements are removed, and the exterior element reduces in size from the enlarged state to the compact state. Also, when empty, the user may clean the device by running water through the passage between the first and second open ends. 
         [0014]    According to a preferred feature of the invention, the exterior element is cooperable with the quantity of the retained liquid to propagate forces imparted by a user against the exterior element of the cavity throughout the cavity, including against the interior element. 
         [0015]    According to a feature of the present invention, the exterior element enlarges to an approximate shape of a female pelvic region and buttocks. To create this shape, another preferred feature of the invention varies the thickness of walls of the exterior element to control the shape when enlarged, and yet another preferred feature provides a yoke of flexible ribs to create natural looking contours. 
         [0016]    According to yet another preferred feature of the invention, a detail portion comprising simulated female genitalia is disposed on the exterior element at the second open end of the interior element. To maintain a natural look, a flexible, inelastic cord may be disposed within the ribs adjacent to the detail portion configured to limit expansion of a region therearound. 
         [0017]    Advantages of the invention include the compact state of the device which is relatively small and inconspicuous to store when not in use, the natural feeling created by warm liquid exerting pressure, rather than tightness, on the user&#39;s penis, and elimination of the unnatural sucking noises and leakage of lubricant and/or seminal fluid during use. The forces exerted on the interior element during use provide a closer approximation of the natural pressures exerted on the penis by a woman&#39;s vagina during coitus. Warm water provides natural body temperature. Forces applied to the exterior element during use result in reactive forces imparted by movement of the liquid that provide dynamic responsive motion of the device, such as thrusting, rocking, swaying, and bouncing. The combination of natural interior pressure, natural body temperature, and responsive dynamic motion make the device feel alive and real when in use.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0028]    Turning now to the drawings wherein a preferred embodiment of the invention is shown, in  FIGS. 1 and 2 , a side perspective view of an erogenic stimulation device  10  for men for use in simulated coitus is shown in a compact state  12  and an enlarged state  14 , respectively. As seen in  FIG. 1 , device  10 , in compact state  12 , may resemble an irregular bottle shape including a bottle neck area  50 , although it is contemplated that the shape can vary according to different embodiments. Importantly, compact state  12  is relatively small and inconspicuous for ease of storage when device  10  is not in use. 
         [0029]    Turning also to  FIGS. 3 through 10 , device  10  includes an exterior element  20  of an elastomeric material disposed about and containing an interior element  40  of an elastomeric material. Preferable elastomeric materials include, but are not limited to, rubber, silicone rubber, other suitable elastomers, and the like. A cavity  24  associated with an opening  22  is defined between exterior element  20  and interior element  40 . Interior element  40  has an elongate overall shape and includes a first open end  28 , a second open end  30 , and a longitudinally extending passage  32  extending therebetween. First open end  28  is disposed in opening  22  of exterior element  20  and second open end  30  is connected to and incorporated into exterior element  20  so as to be open and accessible through exterior element  20  to allow insertion of a penis into passage  32 . 
         [0030]    A closure element, shown in  FIGS. 9 and 10  as a strap  70 , is closable about a portion of exterior element  20  adjacent to opening  22  and about first open end  28  of interior element  40  for sealably closing opening  22  for retaining the liquid in cavity  24  and holding first open end  28  of interior element  40  in the closed opening  22  ( FIG. 8 ). Strap  70  is illustrious of a range of closure elements that are sufficient for constricting bottle neck area  50  and sealably closing first open end  28  and opening  22 . 
         [0031]    According to a preferred aspect of the invention, retaining a quantity of liquid under pressure, preferably warm water, in cavity  24  exerts an external force, represented by arrows denoted A, against interior element  40  and an internal force, represented by arrows denoted B, against exterior element  20  ( FIG. 7 ). Comparison of  FIGS. 3 and 5  to  FIGS. 4 and 7 , respectively, show second open end  30  and passage  32  is reduced in size in at least one direction and exterior element  20  increases in size from compact state  12  to enlarged state  14 . 
         [0032]    This aspect of the invention is advantageous because it results in passage  32  simulating a more natural feeling vaginal tract. As explained above, prior art devices rely on narrow passages that fit tightly around the user&#39;s penis to approximate the vaginal tract. In other words, the user&#39;s penis displaces or stretches the elastic material of the prior art devices on insertion, and the elasticity of the material fighting that deformity causes constriction or tightness around the user&#39;s penis. The present invention, however, uses the resiliency of interior element  40 , in cooperation with the warm liquid under pressure, to create a custom fit to the user&#39;s penis. When entering passage  32 , the elasticity of interior element  40  allows the opening of passage  32 , rather than constrict around the penis, and the forces exerted by the liquid balance the elasticity to prevent interior element  40  from expanding any more than required by the user. As a result, the user feels the forces exerted by the water, which is a much more natural feeling than the constriction of the elastic material found in the prior art. 
         [0033]    As an additional advantage, closing first open end  28  of interior element  40  after the air is evacuated from passage  32  prevents the unnatural sucking noises and leakage of lubricant and/or seminal fluid through first open end  28  which is common in prior art devices. 
         [0034]    According to another preferred aspect of the invention, removal of the quantity of the liquid from cavity  24  removes the external force against interior element  40  and the internal force against exterior element  20  reducing exterior element  20  in size from enlarged state  14  to compact state  12  for convenient and inconspicuous storage. Also, when empty, the user may clean device  10  by running water through passage  32  between first and second open ends  28 ,  30 . When in compact state  12 , interior element  40  tends to return to its cylindrical shape allowing passage  32  to air dry after cleaning. 
         [0035]    According to yet another preferred aspect of the invention, exterior element  20  is cooperable with the quantity of the retained liquid to propagate forces imparted by a user against exterior element  20  of cavity  24  throughout cavity  24 , including against interior element  40 . 
         [0036]    This aspect of the invention is advantageous because as forces exerted on cavity  24  are propagated by the liquid, the user feels the motion of the liquid exerting a responsive pressure against his penis in passage  32 , which provides a closer approximation of the natural pressures exerted on the penis by a woman&#39;s vagina during coitus. Forces applied to the exterior element during use result in reactive forces imparted by movement of the liquid that provide dynamic responsive motion of device  10 , such as thrusting, rocking, swaying, and bouncing. The combination of natural interior pressure, natural body temperature, and responsive dynamic motion make the device feel alive and real when in use. 
         [0037]    According to a preferred feature of the invention, in enlarged state  14 , exterior element  20  approximates a shape of a female pelvic region and buttocks. To create this shape, another preferred feature of the invention varies the thickness of walls of exterior element  20  to control the shape when enlarged, and yet another preferred feature provides a yoke of flexible ribs  90  to create natural looking contours. Ribs  90  are made of a material less elastic than the material of exterior element  20  and are disposed within exterior element  20  to control expansion thereof when in enlarged state  14 . Preferably ribs  90  are fused to exterior element  20  and are configured to contour the shape of exterior element  20  to simulate the pelvic region and buttocks. 
         [0038]    According to yet another preferred feature of the invention, a detail portion  80  comprising simulated female genitalia is disposed on exterior element  20  at second open end  30  of interior element  40 . To maintain the integrity of detail portion  80  when device  10  is in enlarged state  14 , a flexible, inelastic cord  88  disposed within ribs  90  adjacent to detail portion  80  is configured to limit expansion of a region therearound. 
         [0039]    According to yet another preferred aspect of device  10 , opening  22  of exterior element  20  is sufficiently larger than first open end  28  for passage of a liquid into and out of cavity  24 . This aspect, as seen in  FIGS. 6 and 8 , facilitates filling cavity  24  with liquid, preferably water, without filling first open end  28 . A water faucet can be placed in opening  22  between interior element  40  and exterior element  20  for ease of filling. In addition, the thickness of the material of interior element  40  around first open end  28  provides a plug  26  to aid in sealing opening  22 . Plug  26  is created by reducing the inside dimension of interior element  40 , thereby thickening the wall of interior element  40  at first open end  28  as interior element  40  passes through bottle neck area  50 . 
         [0040]      FIGS. 9 and 10  are top and bottom views, respectively, of device  10  in enlarged state  14  illustrating the contours of the pelvic region and buttocks formed by cooperation of exterior element  20  and ribs  90 . 
         [0041]    In light of all the foregoing, it should thus be apparent to those skilled in the art that there has been shown and described a compact expandable erogenic stimulation device for men. However, it should also be apparent that, within the principles and scope of the invention, many changes are possible and contemplated, including in the details, materials, and arrangements of parts which have been described and illustrated to explain the nature of the invention. Thus, while the foregoing description and discussion addresses certain preferred embodiments or elements of the invention, it should further be understood that concepts of the invention, as based upon the foregoing description and discussion, may be readily incorporated into or employed in other embodiments and constructions without departing from the scope of the invention. Accordingly, the following claims are intended to protect the invention broadly as well as in the specific form shown, and all changes, modifications, variations, and other uses and applications which do not depart from the spirit and scope of the invention are deemed to be covered by the invention, which is limited only by the claims which follow.
