The present invention relates to a condom, and more particularly, to a condom having antibacterial and anti-inflammatory activities.
A condom is a contraceptive device that can prevent unwanted pregnancy by preventing sperm from entering the vagina during sexual intercourse. A conventional common is made of a thin rubber material so that it may easily accommodate a male penis, and a lubricant is applied to the outer surface of the condom so that the condom can be easily inserted into a woman's vagina. However, the conventional condom does not have antibacterial and anti-inflammatory activities.
Meanwhile, in recent years, condoms having antibacterial and anti-inflammatory activities have been developed. For example, Korean Utility Model Registration No. 20-0207212 (published on Dec. 15, 2000) discloses a condom containing gold and silver. That is, the condom disclosed therein contains a silver foil or gold and silver together with a lubricant component on the inside or outside thereof so that it may have an effect of preventing bacterial infection as well as a cell regeneration effect or a disinfectant effect.
In addition, Korean Patent No. 10-0884241 (published on Feb. 17, 2009) discloses a condom coated with nano-silver powder which is a material having a strong antibacterial and disinfectant activities.
However, the above-described condoms having antibacterial activity are produced using gold or silver as an active material, and thus have a problem in that the production cost thereof increases.
Therefore, the present invention is intended to solve the above-described problem, and the problem to be solved by the present invention is to provide a condom which is produced at low cost and has antibacterial and anti-inflammatory activities.
A condom according to one embodiment of the present invention comprises: a condom body; and a lubricant layer formed on the outer surface of the condom body by applying a lubricant solution comprising a mixture of a lubricant and a composition for antibacterial and anti-inflammatory activities to the outer surface. The composition contains, as an active ingredient, a combination of four components consisting of a fisetin compound, a Rose damascene extract, a Paeonia suffruticosa Andr. extract, and a Scutellaria baicalensis extract.
The fisetin compound, a kind of flavonoid, may be a compound represented by a molecular formula of C15H10O6.
The fisetin compound may be a compound represented by the following formula:
The Rose damascene extract may be a substance obtained by extraction from Rose damascene which is a small shrub belonging to the family Rosaceae of the order Rosales of Dicotyledoneae; the Paeonia suffruticosa Andr. extract may be a substance obtained by extraction from Paeonia suffruticosa Andr. which is a plant belonging to the family Ranunculaceae of Dicotyledoneae; and the Scutellaria baicalensis extract may be a substance obtained by extraction from Scutellaria baicalensis which is a perennial plant belonging to the family Labiatae of the order Tubiflorae of Dicotyledoneae.
The composition may be produced by mixing the fisetin compound, the Rose damascene extract, the Paeonia suffruticosa Andr. extract and the Scutellaria baicalensis extract together at a weight ratio of 1:0.5 to 1.5:8 to 12:8 to 12.
The composition may be produced by mixing the fisetin compound, the Rose damascene extract, the Paeonia suffruticosa Andr. extract and the Scutellaria baicalensis extract together at a weight ratio of 1:1:10:10.
The lubricant solution may be prepared by mixing the lubricant with 0.001 to 10 wt % of the composition.
According to the condom of the present invention, as the lubricant solution applied to the outer surface of the condom body is produced by mixing the lubricant with the composition for antibacterial and anti-inflammatory activities, the condom may exhibit antibacterial and anti-inflammatory activities in a woman's vagina.
In addition, as the composition contains the extracts produced by extraction from natural plant materials, it is harmless to the human body and may have a function of effectively preventing infection by harmful microorganisms, and the condom may be produced at low cost compared to a conventional condom which is produced using gold or silver as a material.

Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings.
Referring to 1 and 2, a condom according to one embodiment of the present invention is a contraceptive device into which the male penis may be easily inserted and which may prevent unwanted pregnancy by preventing sperm from entering the female vagina during sexual intercourse. The condom may comprise a condom body 10 for accommodating a male penis, and a lubricant layer 20 formed on the outer surface of the condom body 10.
The condom body 10 may comprise: a body portion 12 into which a male penis is inserted and accommodated; a front end protrusion 14 protruding from the center of the front end of the body portion 12; and a side protrusion 16 formed along the edge of the rear end of the body portion 12. The condom body 10 may be made of an elastic rubber material, for example, natural rubber latex.
The lubricant layer 20 may comprise a lubricant solution existing in, for example, a liquid or gel state. In this case, the lubricant solution may be applied to the outer surface of the condom body 10 to form the lubricant layer 20. When the lubricant layer 20 is formed on the outer surface of the condom body 10 as described above, the condom body 10 into which a male penis has been inserted may be easily inserted into a female vagina.
In addition, the lubricating layer 20 may also be formed on the inner surface of the condom body 10. That is, the lubricant solution may also be applied to the inner surface of the condom body 10. When the lubricant layer 20 is also formed on the inner surface of the condom body 10 as described above, a male penis may be easily inserted into the condom body 10.
Meanwhile, a certain amount of the lubricant solution may exist in the inner space formed in the side projection 16. In this case, when the condom body 10 into which a male penis has been inserted is inserted into and moves forward and backward in a female vagina, the lubricant solution present in the inner space of the side protrusion 16 may be discharged to the outer surface of the condom body 10 by pressure and impact.
In this embodiment, the lubricant solution forming the lubricant layer 20 may be a mixture of a lubricant present in a solid or gel state and the composition for antibacterial and anti-inflammatory activities.
In this embodiment, the composition contained in the lubricant solution may contain, as an active ingredient, a combination of four components consisting of a fisetin compound, a Rose damascene extract, a Paeonia suffruticosa Andr. extract, and a Scutellaria baicalensis extract.
The fisetin compound, a kind of flavonoid, may have a molecular formula of C15H10O6, may be represented by the following Formula 1, and can be found mainly in the heartwoods of Anacardiaceae plants in nature.
The Rose damascene extract may be a substance obtained by extraction from Rose damascene which is a small shrub belonging to the family Rosaceae of the order Rosales of Dicotyledoneae; the Paeonia suffruticosa Andr. extract may be a substance obtained by extraction from Paeonia suffruticosa Andr. which is a plant belonging to the family Ranunculaceae of Dicotyledoneae; and the Scutellaria baicalensis extract may be a substance obtained by extraction from Scutellaria baicalensis which is a perennial plant belonging to the family Labiatae of the order Tubiflorae of Dicotyledoneae.
The composition may be produced by mixing the fisetin compound, the Rose damascene extract, the Paeonia suffruticosa Andr. extract and the Scutellaria baicalensis extract together at a weight ratio of 1:0.5 to 1.5:8 to 12:8 to 12 as determined by checkerboard assay. More specifically, the composition contained in the lubricant solution may be produced by mixing the fisetin compound, the Rose damascene extract, the Paeonia suffruticosa Andr. extract and the Scutellaria baicalensis extract together at a weight ratio of 1:1:10:10.
Meanwhile, the composition may have very excellent antibacterial activity. For example, the composition may have excellent antifungal activity against fungi of the genus Candida, more specifically, Candida albicans. In addition, the composition may have excellent antibacterial activity against gram-negative strains of the genus Escherichia, more specifically Escherichia coli, and gram-positive strains of the genus Staphylococcus, more specifically, Staphylococcus aureus.
In addition, as the composition contains the extracts produced by extraction from natural plant materials, it is harmless to the human body and may have a function of effectively preventing infection by harmful microorganisms.
In this embodiment, the lubricant solution may be prepared by mixing the lubricant with 0.001 to 10 wt % of the composition.
As described above, as the lubricant solution which is applied to the outer surface of the condom body 10 is produced by mixing the lubricant with the composition for antibacterial and anti-inflammatory activities, the condom may exhibit antibacterial and anti-inflammatory activities in a woman's vagina.
In addition, as the composition contains the extracts produced by extraction from natural plant materials, it is harmless to the human body and may have a function of effectively preventing infection by harmful microorganisms, and the condom may be produced at low cost compared to a conventional condom which is produced using gold or silver as a material.
