Device for shielding the male organ

A device for shielding the male organ includes a tube having a closed end and an open end which forms a cavity for receiving the male organ through the open end. The device further includes an impermeable membrane which is essentially cylindrical in shape having a proximal end and a distal end, wherein the distal end is circumferentially attached about the open end of the tube and wherein the proximal end has means for securing the membrane to the base of the male organ.

BACKGROUND OF THE INVENTION 
In order to gain satisfactory sexual activity, there are two main desires, 
stimulation of the sexual organs or at least of one partner's organ, and 
security against transmission of disease or when contraception is desired 
of sperm. 
The standard physical device to provide protection against disease 
conception or both is the male condom, a thin membrane which is rolled 
tightly over the male organ. Its major disadvantage is that it largely or 
entirely prevents friction for the male user, thereby reducing or 
eliminating the stimulation of sexual activity. The condom is also awkward 
in use, being difficult to place on the organ and subject to slipping off. 
Because condoms are unsatisfactory to male users, there is a reluctance to 
use them. Consequently, the rates of venereal and AIDS infection, and the 
rates of unwanted pregnancies, are increased. 
As a further disadvantage, condoms are a simple, uniform, and utilitarian 
device. Yet human sexual activities involve an extremely wide variety of 
personal situations for sex, of purposes and interests in sex, of degrees 
of concern about the risk of disease or conception, of types of sexual 
activity, for instance, heterosexual intercourse, manual play, oral 
stimulation, self-stimulation, etc., and of partners' ages and 
preferences. 
Efforts to improve the condom have mainly tried to make it become even more 
insignificant, especially with ever-thinner membranes. There have been 
some efforts to enlarge the tip of some condoms to provide some looseness 
and to alter the surfaces. But those have accomplished little so far, and 
they have raised the risks of the condom's falling off during use. 
"Sex toys," which can simulate some features of the male organ, often in 
exaggerated forms, include a variety of vibrators, with simple 
cylindrical, tapered or male-organ-simulating shapes to be inserted into 
the female. Such vibrators lack the enclosure for the actual male organ, 
the ability to insert the male's own organ fully into the female, and the 
mutual stimulating process. 
Another category is hollow fake male organs, often worn with harnesses. 
They are usually designed for penetration, often with an exaggerated 
exterior size. They are usually made of stiff materials. Particularly, 
they do not provide for a sliding and friction of the male organ inside 
the hollow simulated organ. Also, they are not lined or otherwise prepared 
for stimulation of either partner. Some versions of them are called 
Prosthetic Penis Aids (PPAs). They too are fixed over the male's organ, 
often with a harness, thereby preventing any sliding and stimulation for 
the male. 
Still another category is various pumps and related mechanical devices, 
which a male can use to cause friction or pulsing for his organ. But these 
pumps are large and unwieldy, with no possibility of being used for mutual 
intimate activity in the manner of the invention. 
Finally, there are "extenders" or "extensions," which fasten an elongated 
molded rubber tip of a simulated male organ onto the real organ, seeking 
to make it seem longer. One version even contains a vibrating device. 
These extenders are tightly rolled onto the male organ. There is no 
enclosure of the entire organ. There can be no sliding of the male organ 
inside the extension. There is no anchoring to the base of the real organ, 
and the extension does not provide for secure protection. 
Therefore, a need exists for an improved apparatus that causes sexual 
stimulation for both partners during sexual activity is securely anchored 
without preventing friction; comes in varied shapes, sizes, and surfaces, 
in order to fit human diversity in anatomical sizes and personal 
interests; and provides protection. 
SUMMARY OF THE INVENTION 
The present invention relates to a device that is a shield for the male 
organ. The device includes a tube having a closed end and an open end, 
which forms a cavity for received the male organ through the open end. The 
device further includes an impermeable membrane, which is essentially 
cylindrical in shape having a proximal end and a distal end, wherein it is 
circumferentially attached about the open end of the tube and wherein the 
proximal end has means for securing the membrane to the base of the male 
organ. 
The invention is designed to contain the enlarged male organ within an 
enclosed structure, which can also be soft-surfaced, freely-moving and 
stimulating. The male organ moves freely within this enclosure during 
manual sexual activity or intercourse. It also simultaneously provides the 
female partner with the experience of an inserted, moving, and stimulating 
male organ. It does this by the use of simple, normal sexual motions, 
rather than by artificial postures, mechanisms, or manipulation. The 
device therefore becomes integral to intimate, joint sexual activity, 
providing satisfaction to both partners during intercourse. It can also be 
used for manual stimulation of the male organ and for self-stimulation by 
the male.

DETAILED DESCRIPTION OF THE INVENTION 
The features and other details of the method and apparatus of the invention 
will now be more particularly described with reference to the accompanying 
drawings and pointed out in the claims. The same numeral present in 
different figures represents the same item. It will be understood that the 
particular embodiments of the invention are shown by way of illustration 
and not as limitations of the invention. The principal features of this 
invention can be employed in various embodiments without departing from 
the scope of the invention. 
The invention has a structure which has two main parts, an impermeable 
membrane portion that is relatively thin and flexible, and a closed-end 
tube or sleeve. The total length of the device, the membrane plus the 
tube, while extended is substantially greater than that of the extended 
male organ which it encloses, up to approximately twice the length or 
more. 
The membrane serves as a loose-fitting but tightly-anchored holder, which 
allows the tube to slide along and around the male organ. The membrane 
portion is thin, loose and impermeable. It has at least two embodiments, a 
connector and a larger, complete enclosure. 
In one embodiment, the membrane connects the tube to the base of the male 
user's organ. It is essentially cylindrical in shape, but it is highly 
flexible and large enough to let the male organ slip loosely within it 
and, possibly, to serve as a reservoir to hold excess air. The length of 
the membrane can vary from one or two inches up to nearly, but not equal 
to or longer than the length of the extended organ. In this embodiment, 
the membrane is prepared separately and is then joined by fusion or 
adhesion to the tube during formation. 
In another embodiment, an effective approach is to have a single large 
fabric closed-end tube serve as both the membrane and the core of the 
tube, as shown in FIG. 2. The tube is created by dipping the tube of the 
membrane into spongy material, such as polyurethane, which adheres to the 
membrane and hardens into the desired thickness and consistency. The 
ability of the device to be everted makes it possible to create the body 
and surfaces of the tube by successively dipping the inside, but everted, 
surface and then after turning the device back to its final position 
dipping the outside surface so as to obtain another substantial layer of 
material. In addition, the flange around the opening of the tube may be 
created by applying a thick adhering ring around the device before the 
outside surface is dipped. 
Alternatively, as shown in FIG. 3, the membrane may be part of a longer, 
looser, thin-walled, sleeve-like closed-end tube, which is large enough to 
surround and contain a wholly separate tube, rather than to connect with 
it. The membrane can then be physically separated from the tube, in 
storage and possibly use. However, the outside membrane can be fastened to 
the tube by applying an internal or external tape to the membrane. During 
the invention'use for intercourse, the membrane of the device is anchored 
to the base of the male organ by a narrow strip or strips of adhesive. 
Versions of the membrane may be made of any flexible, impermeable membrane 
or cloth-like material, such as a polymer or treated natural material. The 
membrane may instead be elastic, in some degree, if users desire and made 
from a material typically used for condoms. 
The tube is usually a moderately soft, lightweight and well-fitted 
container for the entire male organ. This portion is like a closed-end 
tube with relatively thick and soft sides and a rounded tip. This tube or 
sleeve is not elastic, though it is soft and usually easily bendable, and 
the thickness of its walls may vary from about 0.125 to 0.5 inches. 
Because it is not stretchable, this container needs to be reasonably well 
fitted in size to the specific user's extended organ. But the fit is 
loose, so as to permit free movement and friction. 
This fit makes it possible for the tube to serve its primary purpose to 
provide well-adjusted stimulation to the enclosed organ as it slides 
freely inside the tube. The tube is lined internally with one or more 
stimulating surfaces or attachments or both. Its external surface may be 
plain, provided with stimulating surface patterns or attachments or both, 
or shaped with anatomical features or a combination thereof. 
As a matter of length, the interior of the tube portion is a little longer 
than the length of the entire extended organ. The exterior of the tube may 
range from slightly longer to much longer than the extended male organ. 
As for weight, the tube can be lightweight, as little as about a half ounce 
or possibly as much as three ounces. The actual weight depends on the 
specific variations in size, structure, composition, methods of 
production, and possible attachments. 
The tube can have many possible variations of sizes, length and 
circumference, thickness of walls, degrees of softness or firmness, 
interior and exterior shapes, surfaces and attachments, colors and other 
decorations. It may have the single membrane embedded within its 
thickness. 
The stimulating surfaces or attachments or both on the interior and 
exterior surfaces may be preinstalled on the device, or they may be 
applied to the device by the user at some time before the device is 
employed. 
The device may be used in its produced form, with complex shapes and 
stimulating attachments already included. Alternatively, before sexual 
activity, the user may prepare the inner or outer or both surfaces by 
applying specific stimulating features. 
The device can be provided in a small, flat stiff-paper envelope or packet, 
intended to be as small, portable, and convenient to open as possible. The 
device can be folded, with the tube usually folded once transversely 
across its middle. The packet can then usually be less than about four 
inches long, three inches wide, and 0.5 to 0.625 inches thick. The packet 
may also contain attachments for the device. Alternatively, the 
attachments may be obtained in a separate packet. 
Both parts of the device can easily be everted. That allows the user to 
adapt and prepare the inner surfaces. The possible attachments have a 
prestick surface so that they can be easily lifted from their holder and 
pressed onto the device in any desired pattern and frequency. The outside 
surface may also be similarly prepared. 
Once the device is prepared for use, and with lubricants inserted as 
desired, it is placed or draped gently over the extended male organ. It is 
not rolled tightly down, as with a condom. Excess air is gently expelled, 
by squeezing the device in a stripping motion from tip to base. The neck 
of the membrane is fastened around the male organ's base, using one or 
more narrow strips of adhesive on the inside or outside or both of the 
neck of the membrane. Note that the adhesive fastenings need not be used 
if the sexual activity is manual stimulation of the male organ. In fact, a 
simpler and cheaper manual-play version of the invention may be produced 
and used, with no adhesive properties. 
Whether it is fastened or not, the device is available for extended manual 
play, by being slid up and down the organ or with twisting strokes or 
both. 
For intercourse, the tube is slid down fully over the male organ, and then 
the device-covered organ is introduced into the female's vagina. The male 
is then free to adopt a piston-like motion within the tube providing 
stimulation to his organ. But the male can also provide stimulation to his 
partner by his actions. By withdrawing his organ out further, the male 
uses the anchored membrane of the device to pull the tube of the device 
partly or nearly entirely out of the female's vagina. Then by sliding his 
organ back into the tube and continuing the motion, the male causes the 
tube to slide fully back into the female. That causes the tube to 
stimulate the female partner as it slides in, as occurs during normal 
intercourse. 
In the process, the device provides both partners with the repetitive 
to-and-fro motion and friction that are characteristic of unencumbered 
sexual intercourse. In addition, the stimulation for both partners may be 
enhanced by the special surfaces or attachments or both that are on both 
the inner and outer surfaces of the device. Lubricants can also be freely 
used as preferred, both inside and outside the device. In fact, partners 
can usually experiment with interior and exterior lubricants, so as to 
obtain the best balance between them. That allows them to get the best 
combination of sliding motions of the device. 
The membrane is a thin, impermeable, flexible, but not necessarily elastic 
sleeve, either as a connector or an enclosing sleeve. It may be a polymer 
cloth or other fabric-like material, or it may be elastic, and large 
enough to be free-sliding along the male organ, or even very loosely 
draped, firmly anchored to the base of the male organ by a strip or strips 
of tape, and provided with a collar at the opening. 
The tube is a soft and lightweight closed-end tube, of spongy materials, 
usually capable of being everted, lined or able to be lined with 
stimulating surfaces and anatomically-simulating devices, on the inside 
and the outside surfaces, usually provided with a flange at its opening, 
and sized to fit specifically over the male user's organ in a gentle 
fashion so that stimulation is promoted by sliding. 
Not only does the device provide for active and repetitive stimulation for 
both partners. It also permits a wide diversity of variations in size, 
shape and stimulating methods, which provide sensations in excess of what 
unprotected sex would create. The female may perceive a larger or 
anatomically different male organ, thanks to the size and shape of the 
tube. The male may perceive a tighter or differently textured vagina, from 
the shape and lining of the inside of the tube. Alternatively, the inner 
and outer conditions of the device may be varied in other ways. Therefore, 
both partners are able to vary their sexual experience, by using different 
versions of the device. 
Moreover, both partners participate and remain in control during the mutual 
sexual activity. The male manages the depth, rate and frequency of his 
insertions and withdrawals. The female also participates by her pelvic 
motions, as in normal unfettered intercourse. Alternatively, during 
foreplay, she can accomplish extensive manual stimulation of the male 
organ using the device, if she wishes to have a shorter interval of 
intercourse activity. 
The invention also insulates the two partners from disease and conception. 
But that is only a secondary result of the device. The invention is 
designed to be integral to the partners' joint sexual activity, under a 
wide variety of conditions. It is to be candidly and skillfully used for 
stimulation, but with much the same motions that are used during normal 
intercourse. Alternatively, it can be used effectively for manual 
stimulation of the male organ. It is not intended to be so thin, plain and 
insignificant that it is not noticed, as compared with a standard condom. 
The device is designed to allow the male organ to move freely and 
vigorously inside them. Friction for the enclosed male organ is provided 
by means of interior surfaces and shapes that can be specifically arranged 
by the user in any desired degree and patterns. The elements to be added 
may simulate inner conditions of a female's sexually active parts. 
Some versions may have anatomically appropriate folds and sliding surfaces 
on the inside of the device. There may be pads, transverse or 
longitudinal, on either the interior or exterior or both. The linings may 
also include patches, rings or lines of hair-like strands. Such strands 
may be short, medium or long up to about one and half inches or even 
longer, and of varying degrees of coarseness and curliness. The linings 
and attachments may also be applied to the exterior surface either of the 
tube or of the membrane. These specially prepared shapes and surfaces may 
vary by locations in the devices, in order to provide the variety of 
sensations and stimulations that are experienced during intercourse, oral 
activity, or manual activity. 
The walls of the tube are thick enough to have structure, body and possibly 
details of shape. Although a standard version may have walls of 
approximately 0.25 to 0.375 inches, the thickness may be less or greater, 
either throughout the tube or merely at specific parts of the device, 
depending on the preferences of the partners. 
The tube may usually may be made of flexible materials such as one or more 
layers or areas of spongy substances, such as lightweight rubber, 
polymers, or similar materials, etc. That consistency provides for a 
preferred degree of softness or stiffness, and the ability to evert the 
tube for preparing both surfaces. The surfaces may be relatively porous or 
smooth, silky or roughened. 
The substances themselves provide an impermeable barrier. Alternatively, a 
barrier membrane may be imbedded in the soft, spongy wall, both for 
impermeability and for extra strength against tearing. 
The device may either be preshaped and prelined, or instead provided in a 
plain shape that can be altered by the user. The total length of the 
device may vary, up to or exceeding twice the length of the extended male 
organ. The tube has an interior space longer than the user's extended 
organ, to allow for free movement. The circumference, thickness and degree 
of firmness may also vary, depending on the users' preferences. 
The device need not be symmetrical or uniform, either externally or 
internally. For example, there may be preinstalled pads or other forms of 
stimulation along one side of the inner surface, but not extending all the 
way around the inner surface. Either in production or in final adjustments 
by the user, the special stimulating surfaces or attachments or both can 
be placed in any parts of the interior, in patches, rings, lines, spirals, 
or other forms. Alternatively, there may be a vibrating ability which is 
placed along one side of the device, or at the tip or both. 
In addition, by production or users' preparation, the device may have an 
external shape which provides to the female partner the experience of a 
larger or differently shaped male organ. Alternatively, the device may 
emphasize only thickness or only length. Also, the device may have unusual 
external shapes, such as a large corona or other ridges, to fit the 
possible interests and preferences of the partner. 
The invention is of light weight, in order not to interfere with the 
desired activity and perceptions. This lightness is obtained by the use of 
foamy or spongy materials, composed of various alternative polymers, to 
form the body of the tube. For instance, a polyurethane is suitable. Also, 
the membrane is comprised of cloth-like or elastic materials, which are 
also very light in weight. Any stimulating attachments and adhesive 
attaching strips are also of minimal weight. 
The degree of stiffness, softness and flexibility of both portions of the 
device may vary. The degree of softness may be affected by the nature of 
the materials or by the thickness of the walls or by both. Some users may 
prefer relatively stiff versions, while others favor soft and pliable 
ones. 
An important part of the invention is the very secure anchoring of the 
device by adhesion at the base of the male organ. That is what permits a 
pulling out and plunging in of the tube, so that the female partner 
experiences friction along with the male partner. The device usually is 
attached by a narrow adhesive strip at the base of the male organ See U.S. 
Pat. application Ser. No. 08/259,602, filed Jun. 14, 1994. The teachings 
of which are incorporated herein by reference. One such strip may be 
preapplied to the inside of the neck of the device. Other strips may be 
applied separately to the base of the male organ, a double-sided adhesive 
band, which then sticks to the preapplied inner strip, or may be wrapped 
around the neck of the device on the outside or both. 
Alternative methods for fastening may be also used, such as using 
Velcro.TM. brand hook and pile fasteners in place of the external strip or 
tabs. Also, some versions of the device may be designed to be used while 
they are placed over the male organ but are not actually anchored to the 
male. An important type of such unattached use would be in order to 
facilitate manual sex activity or masturbation. 
The device must deal with the problem of air. During use, excess air inside 
the invention may cause bulging of the device. Alternatively, it may 
escape, causing unexpected and awkward noises and possibly loosening the 
adhesive attachment. If the tube is quite soft, entrapped air is a minor 
problem. Air may be eliminated from inside the device before it is 
attached. The user merely squeezes out the air after the organ is inserted 
fully into the tube. The reciprocal motion of the male organ then creates 
no internal air displacement and flow. When the male organ is withdrawn 
from the tube, the walls of the tube are collapsed together, because they 
are so soft. Reinsertion of the male organ then enlarges the tube without 
the occurrence of any air flows. 
Alternatively, the tube may be somewhat stiffer, enough so that it retains 
its structural shape and does not collapse during the withdrawal of the 
male organ. Then air must somehow flow into the tube, if the male organ is 
to slide out of it during the withdrawal phase, otherwise, the male organ 
cannot slide and it experience no friction inside the device. 
For air to flow, the tube must have some kind of channel or groove in the 
internal shape of the tube. That requires a proper design of the tube, 
which may involve one or more grooves. The grooves could be provided by 
placing the interior of the tube over a suitable molding device. Such 
grooves can of course be consistent with a stimulating internal surface. 
The out-flowing air from the tube during insertion of the organ is 
contained in the loose volume of the membrane. That loose portion would 
bulge significantly during this phase, but that need not interfere with 
the functioning of the device. The bulging simply occurs outside the 
female's body, and no pressure need occur which might force air noisily 
through the adhesive attachment. In fact, the extra pressure of the air 
bulge around the male pubic area, and around the female's vulva, may 
provide for added stimulation. 
Color and decoration can be an integral element of the invention. Unlike 
the condom, which is minimal and of essentially one color, tan rubber, the 
invention is designed to be noticed, adapted and used. Also the nature of 
the invention permits and encourages the use of interesting colors and 
decorations, for those users who do not wish the invention to mimic flesh 
tones. The use of colors and decorations can introduce elements of style 
and humor, which support and encourage a good experience of sex activity. 
The use of color ranges from restrained and tasteful up to bright and 
entertaining. Color might not seem to be a distinctive feature, but it can 
be. The invention provides a new and more open form of protecting sexual 
activity, and the use of color and decorations can be integral to the 
style, humor and variety of this distinctive experience. 
The membranous cloth for embodiments can be produced by impermeable polymer 
cloth production methods, as are known in the art, which create tubular 
sleeves with one or two open ends. The inner and outer surfaces may be 
selected with specific properties of smoothness, roughness, etc. 
The drawings represent only a few examples among the diversity of possible 
shapes, surfaces, thicknesses, degrees of softness, degrees of 
flexibility, stimulating surfaces, attachments and other possible 
mechanisms, colors and decorations, and methods of attachment. Other 
variations are possible. 
FIG. 1 shows an embodiment of the device as it is removed from its 
container and is held ready to be prepared for use. Notice in FIG. 1 that 
the device is not rolled up before use, in contrast to standard condoms. 
The membrane is loose and flexible, and it has a collar extending outward 
from the neck opening. The collar is used to grasp the device gently 
during insertion of any lubricant and then to place the device over the 
male organ. 
FIG. 1 depicts device 1 with membrane 2 and tube 3. There is a collar 4 at 
the opening 5 of membrane 2. Membrane 2 is large enough to slide or drape 
easily over the extended male organ 8. Tube 3 has a neck opening 6 with a 
flange 7. Tube 3 is shown in a plain version, with unshaped walls 9 that 
are soft on both the interior 11 and exterior 12 surfaces. Membrane 2 is a 
thin, loose, impermeable, non-elastic, membrane 13. 
A narrow strip of adhesive 14 is preapplied to the inside of the neck 5 of 
membrane 2, and that adhesive 14 is covered by removable paper strip 15. 
There is also a preattached, covered adhesive tape 16 around the outside 
of the neck 5, in this version. 
Tube 3 has moderate flange 7 at its opening 6, so that the male's body 17 
can press the tube forward into the female's vagina 18. The inner 11 and 
outer 12 surfaces of tube 3 have the softness and consistency of skin, and 
they are also ready to have specific stimulating surfaces and attachments 
19 applied securely to them if the partners wish. 
FIG. 2 shows an other embodiment, in a cross-sectional view of device 1, 
with a single membrane used for membrane 2 and the core of tube 3. 
FIG. 3 shows another embodiment of the invention. The tube is enclosed in 
the large, long enclosing sleeve. The sleeve has the same adhesive 
elements at its neck as the embodiment in FIG. 1. The sleeve can also be 
prepared with the same external stimulating attachments that, in as the 
embodiment in FIG. 1, are on the outside of the tube. Tube 3 is enclosed 
in sleeve 30. The sleeve 30 can also be prepared with the same external 
stimulating attachments 19 that, in Version 1, go on the outside 12 of 
tube 3. Moreover, the enclosing sleeve 30 can be attached by the user to 
tube 3 with adhesive from the kit, if that is wished in order to provide 
for greater control or security. 
In FIG. 4, device 1 is being placed over the male organ 8 by either partner 
or both. 
In FIG. 5, device 1 is being fastened to the base of organ 8. The covering 
tape inside the neck is removed, the remaining air been squeezed from 
inside the device, and the neck of the device is firmly squeezed around 
the base of the organ. The preinstalled outside tape is then exposed and 
wrapped tightly around the neck 5 of membrane, giving a double layer of 
attachment. The device is ready for use in manual stimulation or 
intercourse. 
The organ, covered by the device, is inserted in the partner's vagina. The 
membrane of the device is compressed accordion-like between the male's and 
female's bodies. Alternatively, it might bulge slightly with air from 
inside the tube. The organ is then withdrawn far enough to pull the tube 
of the invention nearly out of the vagina. The device can now be 
reinserted by a forward movement of the male organ 8. 
FIG. 6 shows a version of the invention 1 whose tube 3 has an anatomically 
shaped form 9, in this embodiment, somewhat exaggerated and fanciful. 
Alternatively, a simple tube 3 could be modified by the user by applying 
attachments 19, in order to give a complex, unusual shape 9. 
FIGS. 7A, 7B, 7C and 7D show cross-sectional views of an alternative tube 
3, which have various thicknesses, shapes and attachments 19. In FIG. 7A, 
there are longitudinal pads, including one with attached hairs. FIG. 7B 
involves a ring of attached hairs. In FIG. 7C, several soft irregular 
lip-like attachments have been applied. In the longitudinal 
cross-sectional views of FIG. 7D, there are pads near the opening, plus a 
strip of soft, lip-like protrusions. 
Equivalents 
Those skilled in the art will recognize, or be able to ascertain using no 
more than routine experimentation, many equivalents to the specific 
embodiments of the invention described specifically herein. Such 
equivalents are intended to be encompassed in the scope of the claims.
