Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a condom provided with a lubricant for protecting human skin.
[0002]
[Prior art]
At present, the mainstream lubricant used for condoms is silicone oil, which is applied to and adhered to condoms. However, since silicone oil is oily, when it adheres to the body, it must be washed off with a detergent or the like.
[0003]
As a solution to this problem, there is a condom lubricant described in JP-A-7-267849. In this technique, squalane is added to a lubricant.
However, in the condom lubricant containing squalane, the rubber films may adhere to each other due to insufficient penetration of the condom into the wound portion.
In addition, as the viscosity of the condom lubricant containing squalane increases, the slimy feeling of the solution can be increased. However, a stringing phenomenon occurs with this.
[0004]
[Problems to be solved by the invention]
The present invention has been made in such a situation.Even if it adheres to the body, it can be easily washed off with water, has excellent penetration into the winding portion and sliminess at the time of use, and uses a condom. To provide a moisturizing condom lubricant that imparts a moist feeling and a condom coated with the condom lubricant, so as to provide a natural feeling by further reducing discomfort caused by doing so. The purpose is.
Further, in the prior art, only oil-based or water-soluble lubricants are used, and additives that can be used are limited, and lubricants that have condom whitening prevention and lubricity at the time of application and condom wearing are used. Difficult to configure.
[0005]
[Means for Solving the Problems]
The present invention proposes the following means to solve the above problems.
As described in claim 1, the lubricant to be applied to the condom is composed of silicone oil, surfactant and water, wherein the silicone oil is 80 to 120 parts, the memphegole is 0.01 to 9 parts, and the purified water is 10 parts. To 50 parts.
[0006]
As described in claim 2, the portion of the condom to which the lubricant of claim 1 has been applied is applied to one or more of the inside, the tip, or the rear of the sac portion for condom semen. .
[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
As a result of many experiments, the present inventor has obtained a lubricant that does not impart greasyness to the skin, gives a moist feeling, and does not whiten rubber used in condoms and the like.
That is, a lubricant is obtained by mixing oil that prevents sticking and whitening of rubber and water that gives a moist feeling to the skin.
80 to 120 parts of silicone oil, 0.01 to 9 parts of memphegol, and 10 to 50 parts of purified water are mixed and emulsified by a mixer or a homogenizer. Thereby, a water-in-oil (W / O type) emulsion can be obtained.
[0008]
In such an emulsion, micelles containing water in oil are dispersed, so that the interaction between oil molecules is inhibited by the micelles. Thereby, even when an oil having a high viscosity is used, the viscosity as a lubricant can be reduced by emulsification, and the elongation of the lubricant is improved.
Further, since the lubricant contains water, it can contain a water-soluble component. Since the water-soluble component is isolated from the oil by the micelle, it can be easily mixed with the lubricant.
Since the lubricant of the present invention is composed of silicone oil, memphegole and purified water, it can be easily washed with water. It can also be removed without leaving a greasy feel by wiping it off with a towel or tissue.
[0009]
As the oil used for the lubricant, silicone oil can be used.
[0010]
As the oil component used for the lubricant to be applied to the condom, silicone oil can be used in consideration of the effect on rubber.
Lubricants using silicone oil as an oil component have stable properties with respect to rubber, prevent adhesion of condoms, and can maintain the properties of condoms for a long time. Further, by adding rosin, the viscosity of the lubricant can be adjusted.
[0011]
By blending and emulsifying purified water and memphegol with silicone oil, the properties of the lubricant itself are low in viscosity, giving a smooth feeling. Moreover, a good fit can be obtained when a condom is worn.
Since this lubricant keeps moisture in micelles formed in the oil, it dissolves in water at a high rate and can be easily washed away with water. Furthermore, when the skin comes into contact with the skin, not all of the contact surface is covered with oil, but moisture adheres to a part of the skin.
[0012]
As described above, the lubricant breaks micelles when it comes into contact with hydrophilic skin and adheres moisture to the skin, but when it comes into contact with hydrophobic rubber etc. Does not come into contact with rubber. Thereby, the whitening phenomenon of the rubber can be prevented.
By forming a lubricating oil by blending purified water and memphegol with silicone oil, the lubricating oil itself has a low viscosity and gives a dry feeling.
By using this lubricant for the condom, the condom can be mounted smoothly, the viscosity is improved after the condom is mounted, and a feeling of fit can be obtained. Further, since this lubricant has an affinity for rubber and has excellent permeability, it is excellent in penetrating into a condom in a rolled-up state, and does not whiten the condom. It gives the condoms a moist feeling and gives the condoms sliminess.
[0013]
In the lubricant, micelles containing water are formed by the oil, and the viscosity of the lubricant decreases. For this reason, the stickiness of the lubricant can be suppressed.
When the condom is attached and the lubricant comes into contact with the penis, water or micelles are adsorbed on the penis surface, and the viscosity of the lubricant increases.
[0014]
As another usage of the lubricant, it can be used as a lotion used during intercourse, and can be used for lubrication at the time of genital insertion. Further, since it is stable against rubber products, it can be used as a lubricant for mounting a wet suit and also as a lubricant for equipment having a rubber seal.
As a silicone oil, a lubricant used for conventional condoms, such as a lubricant for a syringe needle and a syringe, is used, so that safety to a living body can be ensured. For this reason, it can be used as a lubricant applied to the abdomen of the mother's body for echo imaging of the fetus, as a lubricant for inserting the gastroscope into the human body, and as a shaving lubricant.
[0015]
Next, as a surfactant used for the lubricant, memphegol can be used.
Since the surfactant is used as an emulsifier, it is selected according to the oil used. Further, by adjusting the content of memphegol , it is also possible to improve the wet permeability of oil.
[0016]
When used for lubrication of condoms, memphegole can be used. This is because menfegor has a spermicidal effect and can improve the contraceptive rate. In particular, the use of Memphegol can minimize the effects in the vagina.
At this time, by applying a lubricant to the inside of the semen reservoir at the tip of the condom, air can be prevented from entering the condom tip when the condom is attached. Further, a lubricant containing a spermicide is easily brought into contact with sperm ejected from the tip of the penis, so that the sperm mortality is improved and the contraceptive effect is improved.
When the lubricant is applied to the inside of the condom tip, the above effects can be obtained. When the lubricant is applied to the outside of the condom tip, the semen reservoir at the tip of the condom is outside the condom tip by the lubricant. It can be stuck to the side surface to prevent air from entering the semen reservoir during mounting. Further, after the condom is attached, it can be smoothly inserted into the vagina.
When a lubricant is applied to the rear part of the condom, the lubricant can be applied to the entire condom. After the condom is formed, a lubricant is applied or adhered to the rear part of the condom, and when the condom is rolled up, the lubricant adhering to the rear part of the condom is pushed out to the tip side and spreads over the entire condom.
[0017]
In addition, the lubricant using Memphegol can also be used as a lotion for sexual intercourse that is not intended for reproduction.
That is, a spermicide or a bactericide can be added to the lubricant. Many germicides have a surfactant effect, and can be effective as a spermicide or germicide while being added to a lubricant as a surfactant.
Therefore, catechin, sodium cetyl sulfate, undecylenic acid (undecylenate), undecylenic acid monoethanolamide, alkyltrimethylammonium chloride, distearyldimethylbenzylammonium chloride, stearyldimethylbenzylammonium chloride, stearyltrimethylammonium chloride, cetyltrimethylammonium chloride , Cetylpyridinium chloride, benzalkonium chloride, benzethonium chloride, lauryltrimethylammonium chloride, alkyldiaminoethylglycine hydrochloride, chlorhexidine hydrochloride, orthophenylphenol, chlorhexidine gluconate, cresol, chloramine T, chlorxylenol, chlorcresol, chlorphenesin, Salicylic acid (salicylate), alkylisoquinolinium bromide, Cetyltrimethylammonium bromide, domiphen bromide, thymol, thiram, dehydroacetic acid (dehydroacetate), triclosan, trichlorocarbanilide, parachlorophenol, halocarban, phenol, lauroyl sarcosine sodium, resorcin, dodecaethylene glycol monolaurate, One or more of laureth and methoxypropyloxyethylene glycol laurate can be added to the lubricant as a bactericidal or spermicidal agent. In this case, the sterilizing spermicide can also serve as the surfactant component in the lubricant.
[0018]
Various optional components such as a humectant, a humectant, a gelling agent, a neutralizing agent, a fragrance, and a coloring agent can be added to the water contained in the lubricant.
Since the lubricant of the present invention contains water, it can contain a humectant. Suitable humectants used herein include sorbitol, polyethylene glycol, butylene glycol, hexylene glycol, ethoxylated glucose derivatives, hexanetriol, glycerin, water-soluble polyglyceryl methacrylate lubricants and panthenol.
Further, since the lubricant is in an emulsified state, the lubricant has a white color, and the color is good when a colorant is mixed. Food colors such as red No. 106, blue No. 2 and yellow No. 5 can also be added. However, it is desirable to use a water-soluble coloring agent so that it can be easily washed off by washing with water or the like. By adding a fluorescent agent to the lubricant, it is possible to check the remaining lubricant by a black light or to enjoy light emission.
[0019]
Flavors can also be added to the lubricant, such as anise oil, orange oil, clove oil, citronella oil, jasmine oil, camphor oil, spearmint oil, geranium oil, turpentine oil, sandalwood oil, peppermint oil, bergamot oil Add one or more of boad rose oil, eucalyptus oil, lavender oil, lemongrass oil, lemon oil, rose oil, musk, civet, castor, ambergris, anethole, eugenol, geraniol, citroneole, and mentha oil. Can be.
By adding peppermint oil to the lubricant used for the condom, the condom can be given a clean feeling. Also, by adding rose oil, it is possible to promote the enhancement of emotions during sexual intercourse.
[0020]
A configuration for applying a lubricant to a condom will be described with reference to the drawings.
FIG. 1 is a side sectional view of a condom in a rolled-up state.
As a method of applying a lubricant to the condom, there is a method of immersing the condom in the lubricant or injecting the lubricant from a nozzle or the like.
When the condom is immersed in the lubricant, the condom is wound up. The condom is composed of a body, a tip and a semen reservoir.
The torso is configured in a tubular shape and covers the penis root. The tip is hemispherical and covers the glans of the penis. The semen reservoir is formed in a sac shape, is provided at the tip, and projects outside the condom.
[0021]
In the state in which the condom is wound up, as shown in FIG. 1, the condom has the body 2 and a part of the tip 3 wound up.
Then, the condom 1 is immersed in the lubricant in the wound state. For this reason, the lubricant 5 is applied to the semen reservoir 4 and also to the front and back of the tip 3. Since the body 2 of the condom 1 is in a rolled-up state, a large amount of lubricant does not adhere.
This is because the lubricant constituted as described above becomes an emulsion, so that the lubricant is thickened and the permeability decreases.
Since the lubricant 5 is applied to the semen reservoir 4 of the condom 1, when the condom 1 is mounted, the excess lubricant is discharged from the semen reservoir 4 together with air by crushing the semen reservoir 4. Thereby, air can be easily removed from the semen reservoir 4.
Since the lubricant 5 is applied to the distal end portion 3 of the condom 1, it is possible to smoothly attach the condom and insert the penis into the female genitalia.
Since the amount of the lubricant applied to the body 2 of the condom 1 can be reduced, the interposition of the lubricant between the penis root and the condom 1 can be prevented. Thereby, it is possible to prevent the condom 1 from falling off from the penis.
[0022]
The configuration of a condom coated with a lubricant will be described with reference to the drawings.
Lubricants, as described above, 80 to 120 parts of the silicone oil, 0.01 to 9 parts Menfegoru, purified water 10 to 50 parts added, is made by adding a small amount of a preservative such as this. For this reason, the lubricant contains many oily components, and becomes a water-in-oil (W / O type) emulsion by ordinary stirring or the like. That is, the oil component is interposed between the micelles containing the water-soluble component.
For this reason, when the oil component is excessive with respect to the micelle, a part of the oil component may be separated from the lubricant.
[0023]
When a lubricant is applied to the rolled-up condom 1 by immersion or injection, the lubricant hardly adheres to the body 2. However, the body 2 can be protected by the oil component separated from the lubricant.
By using a highly permeable oil component, the oil component can be diffused and the surface of the body 2 can be covered with the oil component. That is, the entire condom 1 can be coated with the oil component coating.
[0024]
FIG. 2 is a partially cutaway side view of the condom, and FIG. 3 is a partially cutaway side view of the tip.
As shown in FIGS. 2 and 3, the lubricant 5 diffuses throughout the inner surface 6 and the outer surface 7 of the condom 1. The condom 1 is covered with the silicone oil coating 8.
Thereby, the condom can be prevented from being oxidized and adhered, and can be easily unwound. However, the lubricant 5 (micelle containing a water-soluble substance) remains in the distal end portion 3 of the condom 1 or the semen reservoir 4, and can ensure lubrication when the penis is inserted.
As described above, in a state where the condom 1 is rolled up, a lubricant is applied to the distal end portion 3 or the semen reservoir 4 to ensure the lubrication of the condom 1 distal end portion 3 and the inner side surface 6 and the outer side surface of the entire condom 1. 7 can be protected.
As the oil component, silicone oil conventionally used for protecting condoms can be used. The silicone oil makes it possible to form a lubricant that can be easily removed from the body while maintaining the conventional antioxidant effect and antiadhesive effect.
[0025]
Further, a jelly agent can be mixed with the lubricant. The jelly may be used conventionally known water, gelatin, sugars and glycerin, the jelly agent disclosed in Japanese Patent Publication No. Sho 41-22237.
As a method of mixing the jelly agent with the lubricant, there are a method of mixing the jelly agent with the lubricant and a method of mixing the jelly agent mixed with the silicone oil with the lubricant.
As a method of mixing the jelly agent with the lubricant, the jelly agent is added to the lubricant and mixed with a mixer. In this case, the jelly agent can be uniformly or non-uniformly dispersed in the lubricant. When uniformly mixed, it is possible to exert the effect of the jelly agent over the entire portion to which the lubricant is applied. In the case of non-uniform mixing, only a few particles of the jelly agent need to be in the area where the effect of the jelly agent is required.Since the jelly agent is not evenly dispersed, the lubricant is not easily affected by the jelly agent, Easy to maintain.
[0026]
As a method of mixing the jelly agent mixed with the silicone oil into the lubricant, the jelly agent is added to the silicone oil and uniformly mixed with a mixer. In this process, the jelly agent is coated on the silicone oil. In a lubricant, micelles are coated with silicone oil, and even when a jelly agent in a similar state is added, the silicone oil intervenes between the micelles and the jelly agent. Therefore, the effects of the lubricant and the jelly agent are maintained.
[0027]
【Example】
The present inventor has repeated experiments based on a number of findings, and as a result, a lubricant that has excellent penetration into a condom rolled-up portion, and does not cause whitening of a condom, under the following conditions, as appropriate, It was confirmed that a plurality of condom lubricants having excellent infiltration into the wound portion of the condom, wettability and sliminess were obtained by mixing or dissolving them.
Silicone oil is used as the oil component of the lubricant, menfegor is used as the surfactant, and purified water is used. In addition, a small amount of additives such as a preservative, a pH adjuster or a thickener are added.
First, silicone oil, water and oil are stirred by a stirrer to form an emulsion. As a result, oil micelles are formed in the silicone oil, and water is present in the micelles.
Add an additive such as a preservative to a solution having a silicone oil content of 100 parts, a memphegol content of 2 to 9 parts, and a purified water content of 10 to 50 parts, and emulsify the mixture with a mixer or a homogenizer. Obtained.
The properties of the obtained lubricant were such that it had a high rate of dissolving in water, had a soft feel, and could easily be removed without any discomfort when attached to the human body.
Further, a preservative, a pH adjuster, and a fragrance may be added to the above lubricant. Depending on the type of pH adjuster or surfactant, the lubricant can be made weakly acidic to further suppress the effect on the skin. Also, by making it acidic, it activates the self-purifying action in the vagina.
When the silicone oil content is in the range of 80 to 120 parts, the memphegol content is in the range of 0.01 to 9 parts, and the purified water content is in the range of 10 to 50 parts, a lubricant close to the above properties can be obtained. In addition, the content of memphegol can be reduced by mixing other surfactants such as alkyl polyoxyethylene ether.
[0028]
The lubricant of the above embodiment is used for a condom.
An example in which a lubricant is used for a condom will be described below.
The lubricant of the above embodiment is attached to the inside of the condom, silicone oil is attached to the outside, and jelly agent is attached to the inside of the semen reservoir.
The condom thus configured can be stored for a long period of time, has no uncomfortable feeling when worn, and can easily wash away the lubricant adhering to the penis with water even after removal. Even when ejaculation is performed in a condom, the lubricant contains surfactant and water, so the lubricant and sperm are easily mixed, and the surfactant contained in the lubricant quickly stops sperm function. Can be Thereby, the effect of contraception can be improved.
[0029]
Next, an example of a method of applying a lubricant to a condom will be described.
The condom that has been rolled up is immersed in a liquid obtained by mixing a lubricant with a jelly agent, so that the mixed liquid is applied to the glans of the condom.
As a result, only the lubricant is separated and exudes from the admixture, and is diffused to the entire inner and outer surfaces of the condom with the jelly remaining. By spreading the lubricant throughout the condom, it is possible to prevent the wound portion of the condom from being stuck and prevent the condom from deteriorating.
[0030]
After winding up the condom, a lubricant is attached to the tip of the condom or the inside of the capsule (semen reservoir). As a result, the lubricant seeps out and diffuses over the entire inner and outer surfaces of the condom. By spreading the lubricant throughout the condom, it is possible to prevent the wound portion of the condom from being stuck and prevent the condom from deteriorating. Further, depending on the ratio of the oil component such as silicone oil in the lubricant, a part of the oil component such as silicone oil of the lubricant can be diffused, and the entire condom can be covered with the oil component such as silicone oil.
Further, after the condom is wound up, it is immersed in silicone oil, and thereafter, a lubricant is attached to the tip of the condom or the inside of the capsule (semen reservoir). Alternatively, after forming the condom, silicone oil is applied, rolled up, and a lubricant is adhered to the tip of the condom or the inside of the capsule (semen reservoir). Also in these methods, it is possible to prevent the wound portion of the condom from being stuck and prevent the condom from deteriorating.
[0031]
【The invention's effect】
As described in detail in the embodiments and examples of the present invention, it is safe for the skin, has a high rate of dissolving in water, has a soft touch, and does not give a feeling of discomfort when attached to the skin. A lubricant which can be easily wiped off from the lubricant can be constituted.
[0032]
In addition, by using a lubricant for the condom, the lubricating property and the moisture retention of the condom and the feeling of touch can be improved, and the condom can be prevented from whitening.
A lubricant can be used as a penetrating agent having an excellent penetrability into the rolled-up portion of the condom, as a lubricating agent that gives a slimy feeling when used. Even if attached to the body, it can be easily washed off with water.
