Figure 12 is the embodiment that is used to implement the mould of manufacture method of the present invention.
Male contraception shown in Fig. 1 is with a tubulose bag or sheath 12, and it has opening end 14 and blind end 16.This bag is a smaller diameter portion 18 from opening end 14, is diameter major part 19 near the helical form elastic construction 20 of nearly blind end 18.
According to an aspect of the present invention, the membranous wall 22 of sheath 12 has elasticity, and condom is worn in user, like this, because its elasticity just can produce first elastic force.Elastic construction 20 can produce second elastic force of condom, can move on the position of stretching and shrinking freely.Elastic construction 20 is integrally formed with die wall 22, in first embodiment, is configured to have on the spiral helicine elastic construction room structure of being separated by groove 24, this room structure by membranous wall 22 radially outwardly, and around membranous wall, thereby forming another elastic force, this will mention hereinafter.
In addition, room structure 24 have one normally, position not stressed, that shrink vertically, as shown in Figure 1.When condom stretched vertically, this room structure made and arrives second position, promptly stretches extended position, as shown in Figure 3.At this moment, circling ring 20a, the 20b of spiral elasticity structure 20,20c are separated from one another, thus produce a kind of elasticity angular force make elastic construction 20 be returned to its normally, position not stressed, that axially shrink.Like this, in use, this condom for man just can be referred to as the condom of " activity ", and it can produce a kind of power of pacifying of (with respect to the condom length direction) vertically in the sexual intercourse process, bring pleasant sensation to men and women in the sexual intercourse process.
Another characteristics of this invention are exactly for people provide a kind of condom, and it is suitable for user wears, and can be so that the part of condom produces a kind of elastic force that condom depends on user body part situation that is independent of.
Therefore, embodiment as Figure 1-3 just can give and use both sides to bring pleasant sensation, because on this condom for man sheath, formed a kind of bottom structure, for example, room structure 24 can freely be located as spring, is returned to the punctured position when loosening from the position of the stretching, extension under the user active force.In addition, in the embodiment of Fig. 1-3, the condom that the elastic force of this room structure has caused a kind of " dual elasticity (spring on spring) ".One of elasticity comes from the elasticity of condom material; Two of elasticity comes from the elastic construction of the condom that the elasticity dual function by Elastic Structural Shape and condom material produced.Major diameter part 19 can make condom separate slightly with user, to avoid dual elastic force because of overlapping to such an extent that too tightly fettered.
Fig. 4 shows that condom for man 30 has a tubulose bag or sheath 32, and it has an opening end 34 and blind end 36.This bag is split into one section small diameter portion 38 from opening end 34, to forming one section major diameter part 39 near second elastic construction, 40 places.This elastic construction is by integrally formed a series of room structures 42 form in the condom for man bottom, this structure can in use be pulled to extended position by punctured position, at this moment, the integrally formed a series of room structures 42 that are arranged in condom 30 bottoms will produce one bounce, and room structure is retracted punctured position.In the embodiment of Fig. 4, this a series of room structure 42 has a trench portions, and formed first series along circumferentially spaced arch portion 42a-42b.This arch portion 42a-42b separates along circumferentially spaced arch portion 42c-42d vertically with second series, and the zone 44 and 46 of longitudinal subdivision is arranged between the above-mentioned arch portion.Zone 44 and 46 has a punctured position, and this moment can be with along circle.Circumferentially the arch portion 42a-42b that also arranges vertically at interval remains position not stressed at the beginning or that shrink in the bottom of condom for man 30, zone 44 and 46 also has one to stretch stressed position, at this moment, in use, be pulled away from arch portion 42c-42d along circumferentially spaced arch portion 42a-42b.Zone 44 and 46 can be independent of envoy's motion, arch portion is returned to their contraction state.The same with first embodiment, the membranous wall 32a of small diameter portion 32 and major diameter part 39 has elasticity, can make condom be attached at user, therefore, because its elasticity has just formed first elastic force.Elastic construction 40 provides second elastic force for condom, and it can be freely, be independent of any user action ground is returned to punctured position with condom by the extended position of locating because of the user action.Elastic construction 40 is integrally formed with membranous wall 32a, and the same with first embodiment, room structure 42 is axially spaced-apart along the circumferential direction around membranous wall by membranous wall 32a radially outwardly, thereby forms the additional elastic force of embodiment as Figure 1-3.Major diameter part 39 can be separated condom slightly with user, to avoid Double spring because of overlapping to such an extent that too tightly fettered.
With as Fig. 1-3 embodiment, the embodiment of Fig. 4-6 revolves structure 42 and membranous wall 32a once, and they are made by thin film, and the pleasant sensation in the use can be provided, enough intensity and impermeability are arranged simultaneously, can prevent to cause in use allowing the body fluid flow mistake because of slight crack or hole appear in membranous wall.Like this, membranous wall 32a and on room structure 42 just can prevent acquired immune deficiency syndrome (AIDS) or other sexually transmitted disease (STD).
As shown in Figure 4, room structure 42 have one normally, not stressed, along a position that axle shrinks.When condom 30 stretches vertically, room structure obtains second and stretches stressed position, as shown in Figure 6, at this moment, arch portion 42a-42b separates with 42c-42d, zone 44,46 is drawn back, thus produce one elastic construction 40 can be returned to normally, not stressed, along the elasticity angular force of axle punctured position.Therefore, in use, this condom for man can be called as the condom of " activity ", and it can produce a kind of power of pacifying (with respect to the condom length direction) vertically in the sexual intercourse process, be independent of user along any action on the axle punctured position direction, bring pleasant sensation to men and women.Like this, the embodiment of Fig. 4-6 just can provide a kind of two-way pleasant sensation, because formed a kind of bottom structure on this condom for man sheath, for example, room structure 42 can freely be located as spring with zone 44,46, is returned to the punctured position when loosening from the position of the stretching, extension under the user active force.And, as embodiment at Fig. 1-3, among the embodiment in Fig. 4-6, the elastic force of this room structure 42 and zone has caused the condom of a kind of " dual elasticity ", one of elastic force comes from the elasticity of condom material, and two of elastic force comes from the elastic construction of the condom that is produced by the shape of elastic construction and condom.
Fig. 7-9 shows that condom for man 50 has a tubulose bag or sheath 52, and it has an opening end 54 and a blind end 56.This bag forms one section small diameter portion 58 from opening end 54, and forms one section major diameter part 59 near nearly second blind end 56 place are sine-shaped, sinusoidal elastic construction 60.
According to an aspect of the present invention, the membranous wall 62 with fixed diameter has elasticity, because its elasticity can produce first elastic force, can make condom press close to user.Elastic construction 60 can produce second elastic force, and it can be independent of the action of user, freely in extended position that is reached by the user action and the motion on the punctured position.Elastic construction 60 is integrally formed with membranous wall 62, the same with first embodiment, its shape makes room structure 64-68 be groove 64a-64b, each groove is the sine curve shape on the condom top, and can be stretched to and stretch stressed position, at this moment, this sine curve shape shape can produce active force, makes it be returned to not stressed punctured position.This room structure 64-68 is by membranous wall 62 radial outward, and around membranous wall, thereby forming another elastic force, this will mention hereinafter.
Membranous wall 62 and room structure 64-68 are made by thin film, can improve the pleasant sensation in the use, and enough intensity and impermeability are arranged simultaneously, can prevent to cause in use allowing the body fluid flow mistake because of slight crack or hole appear in membranous wall.Like this, membranous wall 62 and on room structure 64-68 just can prevent acquired immune deficiency syndrome (AIDS) or other sexually transmitted disease (STD)s.Major diameter part 59 can make condom separate slightly with user, to avoid dual elastic force because of overlapping to such an extent that too tightly fettered.
In addition, elastic construction 64-68 have one normally, not stressed, along the position that axle shrinks, as shown in Figure 7.When condom was axially drawn back, room structure just obtained the second position, and it is stressed, stretching, extension, as shown in Figure 9.At this moment, the shape as the ring 64-68 of sine curve shape of elastic construction 60 makes that the distance of the crest of this sine curve shape and trough is bigger, thus can produce one can make elastic construction 60 be returned to it normally, not stressed, along the elasticity angular force of the position that axle shrinks.Like this, in use, this condom for man can be called as " activity " condom, and it can produce a kind of (with respect to condom length direction) vertically freely and pacify power in the sexual intercourse process, bring pleasant sensation for the men and women in the sexual intercourse.This be because this room structure that is the sine curve shape at them when the direction of punctured position is returned to its punctured position by relieving vertically, can and masculinity and femininity produce relative motion.Another characteristics of this invention are, the condom of designing very and body and can in use produce the location, make the part of condom produce and are independent of the elasticity that user is worn situation.
Therefore, embodiment shown in Fig. 7-9 can provide a kind of two-way pleasant sensation by the polycrystalline substance of condom for man, for example, room structure 64 can be independent of the action of user, is returned to punctured position as spring by the extended position that reaches because of the user action.And, in the embodiment shown in Fig. 7-9, the condom that the elastic force of room structure has caused a kind of " dual elasticity ", one of elasticity comes from the elasticity of condom material; Two of elasticity comes from the elastic construction of the condom that the elasticity dual function by Elastic Structural Shape and condom material produced.
In the embodiment of Figure 10, condom for man 70 has certain shape and room structure, can form a series of along circumferentially spaced arch portion, they and other one axially separate along circumferentially spaced arch portion, like this, the longitudinal separation band just has the position of a contraction to keep the primary importance along circumferentially spaced arch portion, also have one simultaneously and stretch stressed position, when this position, if in use be elongated, just have strand active force and these arch portion are returned to their punctured position along circumferentially spaced arch portion.But in this embodiment, circumferentially spaced arch portion forms arcual room structure of embodiment or groove 72-78 as described above, (being half circumference in this embodiment), but it should be noted that we are also considering the less arc of radian.Each semicircle is the relative both sides at the condom circumference of being crisscross arranged.With previous embodiments, the condom sheath has a small diameter portion 77 and major diameter part 79.
In the embodiment of Figure 11, condom for man 80 has along circumferentially spaced arch portion, they are along a plurality of diverse location interlaced arrangement of the whole length direction of condom arch section 82,84,86 in the circumference both sides, have a small diameter portion 88 and major diameter part 89 at different condom sheaths.
