Technical Field
This invention relates to a condom, and more
specifically, to a condom which can be fitted without the
fingers touching the penis or the condom body, to a condom
which is easy to fit and air does not enter when the condom
is to be fitted, and to a condom wherein air does not enter
or remain in a sperm retention part or the vicinity of the
glans part.
Background Art
According to the prior art, condoms are fitted by
breaking the seal of a package, removing the condom body and
fitting it on the penis with the fingers, but as the fingers
touch the penis and the condom body when it is fitted, there
is a problem as to hygiene and whether the condom fits
satisfactorily, and if any lubricating oil or powder is used,
it adheres to the fingers and must therefore be wiped off.
Further, as air enters the condom body, the air must be expelled
when it is fitted, which was a nuisance.
A method has been proposed wherein the condom body is
provided with a fitting tape having grip parts which is rolled
up together with the condom, and when the condom is to be fitted,
these grip parts are pulled, e.g., as disclosed in Japanese
Patent Publication Hei 2-33765, Japanese Patents Laid-Open
Hei 8-56978 and Japanese Utility and Design Patent 3029333.
However, the condom body cannot be fitted without removing
from its package, so it must again be touched with the fingers .
In another type of condom fitted without removing it
from its package with the fingers, and without touching the
penis or condom body with the fingers while it is still in
its package, a fitting tape is rolled up together with the
condom, an extension part is formed beyond this rolled part,
and the tip of this part is sealed to the rim of the package,
as disclosed in, e.g. , Japanese Patent Laid-Open Sho 63-195823,
Japanese Patent Publication Hei 3-505173, Japanese Patent
Publication Hei 10-510452 and Japanese Patent Laid-Open Hei
11-19110.
However, although these proposals (creative ideas)
describe how to fit the condom without touching it with the
fingers, it is difficult in practice to fit the condom without
touching it. Further, there are a large number of parts and
steps involved, the construction is complex and manufacture
is difficult. Stability and reliability of steps could not
be expected, no consideration was given to maintaining the
length of the extension part formed at the tip of the rolled
part at a predetermined length, and the condom body unrolled
when the package was opened. Due to these manufacturing
problems, the product was not commercialized.
If the extension part is short, the fitting tape is pulled
and the rolled part is also pulled out when the package is
opened, so the condom body is unrolled too much, and if it
is fitted in this state, air remains in the glans part. On
the other hand, if the extension part is long, although the
condom body does not unroll too much when the package is opened,
the fitting tape is pulled out too long after opening the package ,
and the condom body droops down when it is fitted. Hence,
it was not easy to fix it on the glans, the fitting stroke
was too long, and the user's thigh and hand interfered with
each other which made fitting difficult.
The problem common to all these ideas was that, as the
tip of the extension part and the rim of the package were sealed
simultaneously, the expected length of the extension part
easily tended to increase or decrease . Due to the construction
of the product, in the steps leading to the final step of the
packaging, this could not be resolved and manufacture of the
condom was therefore difficult. Moreover in these proposals ,
no consideration whatever was given to maintaining the length
of the extension part within a predetermined range , or to means
to achieving that end.
In these condom bodies, there is a sperm retention area
in the glans part. Air entered the sperm retention area when
the package was opened or the condom was fitted, and remained
after the condom was fitted.
There have been proposals for designs which expel the
air in the sperm retention part, but in practice, there was
still a risk that air would enter when the condom was fitted.
As there is a sperm retention area in the glans part,
a considerable amount of air is trapped when the package is
opened and the condom body is fitted, and it was difficult
to expel this air completely. Due to this accumulation of
air, the rubber film of the condom body does not fit closely
around the glans, various fatal problems tended to occur such
as loss of sexual sensation, a tendency to rupture of the condom
body or the condom body easily falling off the penis . To expel
the retained air, it was necessary to touch the condom body
or the penis with the fingers which gave rise to the above
problems or difficulties of usage.
To open the package, it must be split into two equal
parts, and as it is generally difficult to split it precisely
into two parts, the idea was conceived of providing a seam
approximately in the center of the front and rear surfaces.
However, it is difficult to make the starting and finishing
points of the seam coincide precisely on both the front and
rear surfaces during packaging and sealing.
It is therefore an object of this invention to provide
a condom wherein an extension part of predetermined length
is provided in a fitting tape which is rolled up together with
the condom body, i.e., beyond the rolled part. The tip of
the extension part is fixed to a predetermined position of
the packaging before the package rim is sealed in one piece
so that its length does not fluctuate in the packaging step.
The package material of the rim of the condom body is then
sealed. The condom body can suitably be fixed on the glans
without directly touching the penis or condom body, and without
unrolling the condom body more than necessary when the package
is opened. Hence the condom can be fitted without touching,
and furthermore, air does not enter between the glans and the
condom when the condom is fitted.
Disclosure of the Invention
According to this invention, when the condom body is
rolled up, a pair of fitting tapes are laterally disposed to
the left and right of the condom body. One end of these fitting
tapes is disposed in the vicinity of the opening of the condom,
the tapes are rolled up together with the condom body along
its opposite lateral surfaces,' and extension parts are
respectively provided in the vicinity of the glans beyond the
rolled part of the fitting tapes. After the tips of the
extension parts are sealed in one piece with the inner surface
of one of the upper package material and lower package material
of the package, the other package material is placed over the
condom body, and the rims of the package materials are sealed
at positions slightly removed from the rim of the condom so
as to enclose the condom body. In this way, the extension
parts can be maintained at a predetermined length in a step
wherein the rolled condom body is made into a sandwich shape
by the upper and lower package materials, or in an immediately
following step wherein the rim of the condom body is
thermocompression bonded.
The seal part between the extension part of the fitting
tape and the upper package material is set at about 2/3 of
the radius from approximately the outer circumference of the
condombody towards the center of the condom. Hence, the length
of the extension part is rationally determined within the
optimum range from the viewpoint of manufacturing technique,
and can be set to the most preferable length.
This resolves the defects inherent in having the
extension part of the fitting tape too short, and the
disadvantages and difficulties involved in having the
extension part too long. As a result, the condom can be
suitably fixed on the glans without directly touching the penis
or the condom body with the fingers, i.e., a "no touch" fitting
is possible.
It. is preferred that the glans part of the condom body
is fashioned in the shape of a close-cropped monk's head. As
there is no sperm retention area in the glans part, there is
no risk that air will enter the condom body when it is fitted,
and no concern that air will remain. Therefore, the condom
is free from the aforesaid problems and disadvantages
associated with entry of air.
According to this invention, before sealing the tip of
the fitting tape to the package rim in one piece, the extension
part is sealed to the upper package material or lower package
material of the package. Hence, the extension part need not
be eliminated, the shape of the extension part can be maintained,
and it can be firmly sealed to the package rim without the
tip (excess length) of the fitting tape biting. This also prevents rolling back of
excess condom body due to temporary interruptions in pulling the fitting tape, or
to sudden pulling under a load.
According to this invention, a notch for opening the package is provided
substantially in the center of the upper end, and plural rows of tear lines are
provided in the package opening direction substantially in the center of the upper
package material or lower package material, or in both, along the notch. As a
result, the roughness of the package rim disappears, opening the package is
easier, and as tear lines coincide with other parallel tear lines, even if the
positioning of a tear line is slightly to the left or right of the predetermined
position in the package forming step, smooth opening of the package is
enhanced.

Best Modes for carrying out the Invention
This invention will now be described in further detail
with reference to the drawings.
A condom according to this invention basically comprises
a condom body A, a pair of fitting tapes B to the left and
right, and a package C. Before a rim c of the package C is
sealed 9 by thermocompression bonding, the fitting tape B is
sealed 3 to the inner surface of an upper package material
1 or lower package material 2, and the rim c of the package
C is then sealed 9 so as to enclose the condom body A.
The condom body A of this invention is formed as an
ordinary thin film cylindrical envelope of latex rubber or
synthetic resin known in the art in this kind of technical
field. There is no restriction on its shape, i.e., there may
be a sperm retention area in a glans part a or it may be shaped
as a monk's head without a sperm retention part. The monk's
head shape is preferred to prevent entry or retention of air,
the tip is preferably formed in a flat, curved shape, and a
coil is formed in the opening. The coiled width (diameter)
is preferably the same as the standard width for products in
common use, or a larger diameter than the standard width for
products in common use. The pair of fitting tapes B on the
left and right are wound together along the opposite lateral
surfaces of the condom body A, and these tapes B are housed
in the package C such that they are somewhat coiled by winding.
According to this invention, the coiled width (diameter)
of the condom body A is preferably effectively equal to that
of the standard diameter of products in common use, or a larger
diameter than the standard width for products in common use.
By making the width a large width of approximately 53-59 mm
(diameter approximately 34-38 mm) in comparison to the coiled
width of products in common use, which is approximately 51-52
mm (diameter approximately 32-33 mm), idle rotation of the
condom on the glans when the condom is fitted is prevented.
Hence, when the diameter of the condom body A is formed
larger than the standard diameter common products, the condom
can be fitted smoothly without idle rotation on the glans when
it is fitted as described hereabove, it fits easier on the
glans by making the glans part a flat, and fitting by the fitting
tapes B is made still easier.
The flat, curved shape of the tip refers to the relation
between the radius of the condom body A and the diameter of
the apex of the glans part a, where a flat shape resembling
that of a crushed hemisphere is preferable.
The fitting tapes B are tapes of suitable width
comprising any flexible, pliable material such as paper or
plastic which can be rolled together with the condom body along
the opposite lateral faces of the condom body A, e.g. , a pair
of low density left/right polyethylene tapes of width
approximately 10 mm. One end of each of the fitting tapes
B is situated in the vicinity of the opening of the condom
body A, and the other ends are situated to the left and right
along the outer surfaces of the condom so that they can be
extended towards the glans part of the condom, and rolled up
together with the condom body A. Extension parts 5 are formed
in the left and right fitting tapes B beyond a coiled part
4, i.e., in the vicinity of the glans part a, and the tips
of the split extension parts 5 are sealed 3 in one piece with
the inner surface of one of the upper package 1 or lower package
2 prior to sealing the rimc of the package C by thermocompression
bonding or the like.
The position of this seal part 3 may be situated more
towards the inside (Fig. 2) or outside (Fig. 6) than the outer
circumference of the rolled up condom body A, and although
it is not the only possible arrangement, the length of the
extension part 5 is determined by this seal 3.
After opening the package C, the condom body A is unrolled
and fitted by pulling package pieces C' to the left and right
of the part where the pair of left and right fitting tapes
B used in this invention are sealed (3), downwards. It is
therefore indispensable to form the extension parts 5 in a
predetermined length in the left and right fitting tapes B
so the condom body A does not roll out when the package is
opened, and the condom body A does not droop after the package
is opened. Therefore, the length of the extension parts 5
is set in a predetermined range, and they are provided equally
to the left and right on the front surface or the rolled rear
surface in the vicinity of the glans a. The sealing 3 of their
tips to the inner surface of one of the upper package 1 and
lower package 2 prevents recoiling of the condom body A
immediately after the package C is opened, avoids forming an
excess extension part in the fitting tapes B, and makes it
possible to fit the body A appropriately on the glans without
directly touching it with the fingers , i.e. , a "no touch" fitting
is possible.
The length of this extension part 5 is chosen within
a suitable range such that, after opening the package C, subject
to the condition that the condom body A has been fully exposed
from the split package pieces C', the condom body A does not
recoil. To prevent the fitting tape B from being excessively
drawn out after opening the package C, its length is a length
such that the tear ends of the package pieces C' are external
tangents to the condom body A when the condom body A is fitted
on the glans in intimate contact therewith, as shown in Fig.
14 and Fig. 15. Its minimum required length is given by the
following equations (1), (2) (Fig. 17).
When the seal part 3 is situated further inside than
the outer circumference of the condom body A, equation (1)
is used, and when it is situated further outside, equation
(2) is used.
E = r + πr + R- x .............(1)
E = r + πr + R +x .............(2)
where
R = radius of external diameter of condom body A
r = radius of rolled part of condom body A in which fitting
tape B is also rolled
x = distance from outer circumference of condom body A to seal
part 3
E = length of extension part 5
The above equations (1), (2) refer to the case where
the seal 3 is to the upper package material 1 in a center split,
and when the seal part 3 is sealed'to the lower package material
2 or when it is unequally divided to the left and right, the
length may also be calculated based on them.
The distance x from the outer circumference of the condom
body A to the seal part 3 is basically arbitrary, but if a
value of x is used where the following inequality (3) is
satisfied, the condom body A is exposed from the package C
and pulled out further, which is undesirable.

The length of the extension part 5 at this time is given
by the following equation (4):

The extension part 5 becomes longer the nearer the seal
part 3 approaches to the rim c of the package C outside the
outer circumference of the condom body A, and as excess slack
may be trapped in the seal (thermocompression bond) of the
rim, the distance x from the outer circumference of the condom
body A to this seal part 3 must be a suitable magnitude, and
preferably small.
The minimum length occurs when the seal part 3 is sealed
to the upper package material 1 at about 2/3 of a radius toward
the center (toward the inside) of the condom body A from the
outer circumference of the condom body A, and the length E
of the extension part 5 at this time satisfies the aforesaid
equation (1), which is most preferable.
It is practical to provide the extension part 5 larger
than E computed from the above equations (1) , (2) , but if it
is made too large, the condom body A is pulled out too far
from the; package pieces C' and droops after the package is
opened, which gives rise to the above problems . It is therefore
best not. to adhere strictly to the aforesaid equation, and
to allow a tolerance of several mm (e.g. , -3 mm to +5 mm) in
1/2 of the external radius R when the condom body A is rolled
up together with the fitting tape B.
By sealing the end of the extension part 5 determined
by the aforesaid method in one piece with the inner surface
of one of the upper package material 1 or lower package material
2, the extension part 5 can be maintained at a predetermined
length, entry of air to the glans part a due to the unrolling
of the condom body A immediately after the package C is opened
can be prevented, drooping of the condom body A due to excess
withdrawal of the fitting tape B can be avoided, and the body
A can be appropriately fitted on the glans . Further, the grip
hand and thigh of the user do not interfere with each other.
As described above, this extension part 5 is formed by
rolling up the fitting tape B together with the condom body
A, dividing the fitting tape B to the left and right for
predetermined lengths beyond the coiled part 4, i.e., on the
front surface in the vicinity of the glans or on the coiled
rear surface, and sealing 3 the ends of this divided material
to the inner surface of one of the upper package material 1
or lower package material 2 of the package C. This seal part
3 between the fitting tape B and package C is preferably formed
by adhesive or thermocompression bonding at a position removed
from the peripheral seal between one of the upper package
material 1 and lower package material 2 and the fitting tape
B, which is a position in the vicinity of the coiled part 4
of the condom body A, prior to sealing 9 the rim c of the upper
package material 1 and lower package material 2 . However an
extension part of predetermined length can still be maintained
even if the position of the seal part 3 is the rim c of the
package C as in Fig. 9, and it may also coincide with the position
of the seal part 9 of the rim c which is sealed later.
This is because if the seal 9 by thermocompression
bonding of the rim c of the upper package material 1 and lower
package material 2 , and the seal 3 by thermocompression bonding
with the fitting tape B, are formed in one operation
(simultaneously), the position of the fitting tape B tends
to shift, and there tends to be scatter in the length and
orientation of the extension part 5, which are not constant.
Therefore, the seal 3 between one of the upper package material
1 and lower package material 2 with the fitting tape B beyond
the extension part 5 is formed before the seal 9 of the rim
c between the upper package material 1 and the lower package
material 2. In this way, the length and orientation of the
extension part 5 of the fitting tape B are more precise, and
the extension part 5 can be tightened before fitting without
peeling off the seal 3 when the package is opened.
Due to this seal 3, the end of the fitting tape B can
be brought up to the seal 3, and an excess length 6 beyond
this may be left as it is or extended to the peripheral part
c of the package C, and sealed simultaneously when the seal
9 of the rim c of the package C is formed between the upper
and lower package materials 1,2. Thus, if the excess length
and end of the fitting tape B are gripped between the upper
package material 1 and lower package material 2 so that the
end of the fitting tape B is also firmly sealed in one piece
with the package materials 1, 2, a product can be obtained
which is temporarily sealed even if the seal 3 is peeled off
when the package is opened.
In the package C, the condom body A which is rolled up
together with the pair of left and right fitting tapes B is
fixed to the upper package material 1 or lower package material
2. To maintain the extension part 5 of predetermined length
beyond the rolled part of the fitting tape B, after sealing
3 to the inner surface of one of the upper and lower package
materials , the other package material is placed over the condom
body A so that the condom body A is sandwiched, and then the
seal 9 is formed by thermocompression bonding, etc., of the
peripheral part c of the package materials slightly removed
from the condom body A so as to enclose the condom body A.
An opening notch 7 such as for example a V-shaped notch or
a straight indent is provided in the center part of the rim,
and plural rows of tear lines 8 for opening are formed
substantially in the center of one or both of the upper and
lower package materials.
The package materials 1, 2 comprise films or package
materials having thermocompression bonding properties known
in the art in this kind of technical field. For example, the
upper package material 1 comprises a transparent plastic film
and the lower package material 2 comprises an aluminum foil
package material wherein a sealant is laminated, but the
aluminum foil package material 1 may also be an aluminum foil
package material wherein a sealant is laminated. Too much
openingof thepackage can be prevented, and fitting is assisted,
by displaying the position on the upper package material 1
where the package is to be gripped (held) by both hands, and
the left and right thumbs are to be placed when the package
is opened, or by printing instructions to be used when the
package is opened. Regarding the position of the thumbs, the
tips of the left and right thumbs , or the left and right thumbs ,
are displayed substantially parallel so that the package C
is held by the left and right hands, the notch 7 is gradually
opened, and the thenars (or bases) of the left and right thumbs
come in contact before the package is torn open to the end.
The sealant of the upper and lower package materials
1, 2 and the fitting tape B is preferably comprised of a
polyolefine having good heat seal properties (polyethylene,
random polypropylene or EVA) , polyethylene beingparticularly
convenient.
The tear line 8 is generally straight like a "seam",
but rectilinearity may be conferred by providing a slanting,
thin part in the shape of the Japanese letter "ha" or an inverted
Japanese letter "ha" in the opening direction substantially
in the center of one or both of the package materials on the
front and rear surfaces by die pressing or embossing, as shown
in the drawings. This tear line, which is used for opening
the package, is a thin part which is formed in the shape of
the Japanese letter "ha" or an inverted Japanese letter "ha"
by applying a predetermined pressure from the front and rear/
surfaces of the package materials 1, 2 in the shape of the
Japanese letter "ha" or an inverted Japanese letter "ha", as
described above. By forming plural.(e.g. 2-7) rows of the
tear lines 8, the package can be opened efficiently without
any shift in the tear direction (opening direction) along the
notch 7 in the center part of the upper end of the package
C even if the starting and finishing points of this opening
tear line on the front and rear surfaces do not perfectly
coincide.
This tear line is not limited to the shape of the Japanese
letter "ha" or an inverted Japanese letter"ha". Rectilinearity
can be conferred in the way the package is opened and ease
of opening canbe enhancedby forming the tear line in a staggered
shape as a combination of slanting lines and a straight line,
such as for example in the shape of a letter "Y" or an inverted
letter "Y", or a shape wherein a slanting line is slightly
shifted up or down so that the extrapolation of one slanting
line intersects with the other slanting line.
Industrial Applicability
Next, the method of using the condom according to the
invention will be described.
As shown in Fig. 10, the package C is gripped with both
hands by placing the thumbs in the thumb grip positions
displayed on the front surface of the package C and placing
the four fingers of the left and right hands on the rear surface ,
the package is gradually torn open from the notch 7 to the
end along the tear line 8 with the little fingers of the left
and right hands still in place (Fig. 11) , the thenars (bases)
of the thumbs of both hands come in contact and the contact
parts are gradually separated (Fig. 12). The parts are
completely separated up to the end of the package C, the
separated package pieces C' are pulled apart while they are
still gripped and the extension parts 5 of the fitting tape
B are pulled out so that the condom body A does not roll back.
Opening is temporarily stopped in the state shown in Fig. 14,
the condom body A is placed in intimate contact with the glans
(Fig. 15) , and the package pieces c', which are split into
two, are pulled toward the base of the penis. The fitting
tape B and condom body A are then rolled back (Fig. 16) so
that it is completely fitted over the penis with the fitting
tape B peeled away from the condom body A.
