JP2001224618A - Infiltrating agent of water-soluble rolling part for condom and condom coated with the same - Google Patents

Abstract

PROBLEM TO BE SOLVED: To eliminate poor appearance of a condom as caused by the whitening thereof associated with the suction of water, inevitable degraded material quality and the like noted as failures frequently occurring in addition to failed unrolling on use in the conventional method using a water-soluble lubricating agent evidently attributed to its inferiority in infiltration into the rolling part of the condom which causes the rubber film thereof to stick together after the condom rolled up is coated therewith, though it has been employed as solution to silicon oil mainly used for a lubricant oil of the condom from those as suggested in various ways of use to overcome its shortcoming of its nature as oil which unavoidably makes it hard to clean once adhering to a human body or fabrics. SOLUTION: An aqueous solution in which either one or two or more of sodium lactate, trimethyl glycine, sodium dl-malate and monosaccharide is dissolved is used and the water content of the aqueous solution is held within a specified range.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water-soluble lubricant applied to a condom, and a condom coated with the water-soluble lubricant, and more particularly to a rolled-up condom having excellent penetration into a roll-up portion. The present invention relates to a water-soluble wound part penetrating agent which does not cause whitening of a condom and is easy to wash off.

[0002]

2. Description of the Related Art Conventionally, silicone oil has been mainly used as a condom lubricant, and if silicone oil is applied to a condom before winding it up, it becomes difficult to wind up the condom. For this reason, condoms are rolled up into a shape for packing and shipping, and then silicone oil is applied and adhered to the condom. However, since silicone oil is oily, it is not easy to wash it off when it adheres to the body or clothing.

[0003] As a solution, various water-soluble lubricants have been proposed. However, even if the conventional one is applied to a rolled-up condom, the rubber film sticks to each other because it does not easily penetrate into the condom rolled-up part, and cannot be rolled down during use. Problems such as deterioration or deterioration of physical properties often occurred.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of such circumstances, and can be easily washed off even if it adheres to the body or clothing. A water-soluble wound-up penetrant for condoms that is excellent and does not whiten the condom due to water absorption.
An object of the present invention is to provide a condom to which the wound portion penetrant has been applied.

[0005] The above object is achieved by a condom water-soluble wound part penetrating agent and a condom coated with a condom water-soluble wound part penetrating agent described in the claims. That is,

(1) A water-soluble condom-infiltrating portion penetrating agent for condoms which uses an aqueous solution which is excellent in infiltration of a condom in a rolled-up state into a wound portion and does not cause whitening of the condom. (2) An aqueous solution that excels in penetrating into the rolled-up part of the condom in a rolled-up state and does not cause the condom to whiten,
(1) The condom water-soluble wound portion penetrating agent according to (1), which is an aqueous solution in which one or more of sodium lactate, trimethylglycine, dl-sodium malate, and monosaccharides are dissolved. (3) A condom coated with the condom water-soluble wound part penetrating agent according to any one of (1) and (2).

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION As a result of repeated experiments based on many findings, the present inventor has found that a plurality of water-soluble winding portions having excellent suitability as a condom winding portion penetrant under the following mixing conditions. It was confirmed that an infiltrant was obtained.

[0008] (1) When an aqueous solution of sodium lactate is used alone, when the aqueous content of the aqueous solution is within a predetermined range, the aqueous solution exhibits excellent infiltration into the condom roll-up portion, and the If the amount is less than the predetermined range, sufficient penetration cannot be obtained,
Condom whitening occurred in a region beyond the predetermined range.

(2) When the aqueous solution of trimethylglycine is used alone, when the water content of the aqueous solution is within a predetermined range, the trimethylglycine exhibits excellent infiltration into the wound part of the condom, and the water content is reduced. Below the predetermined range, trimethylglycine did not dissolve in water, and condom whitening occurred in the region beyond the predetermined range.

(3) When an aqueous solution of dl-sodium malate is used alone, when the water content of the aqueous solution is within a predetermined range, the aqueous solution exhibits excellent infiltration into the wound portion of the condom, If the content is less than the predetermined range, d
Sodium l-malate did not dissolve in water, and whitening of the condom occurred in a region exceeding a predetermined range.

(4) When an aqueous solution of xylose, glucose, and fructose among monosaccharides is used alone, excellent infiltration into the condom rolled-up portion is obtained when the water content of the aqueous solution is within a predetermined range. When the water content was less than the predetermined range, the monosaccharide did not dissolve in water, and in the region exceeding the predetermined range, whitening of the condom occurred.

(5) When an aqueous solution obtained by mixing two or more aqueous solutions of sodium lactate, trimethylglycine, dl-sodium malate, and monosaccharide is used, a mixed solution of sodium lactate and trimethylglycine is used. When the water content is within a predetermined range, it exhibits excellent infiltration properties with respect to the condom winding portion, and may not be dissolved in water when the water content is less than the predetermined range,
Condom whitening occurs in a region beyond the predetermined range. In addition, when the water content of the other two or more kinds of mixed solutions is within a predetermined range, the condom rolled portion exhibits excellent infiltration properties, and when the water content is less than the predetermined range, it dissolves in water. The condom may be whitened in a region where the water content exceeds a predetermined range.

[0013]

As described above, according to the present invention, it is possible to eliminate the difficulty of the conventional oil-based lubricant such as silicone oil, which is difficult to wash off when it adheres to the body or clothing, and to easily remove it with water. The condom roll-up portion penetrates the condom roll-up portion that can be washed off and does not cause the problem of infiltration into the condom roll-up portion which the water-soluble lubricant proposed so far has and the condom whitening due to water absorption. And a condom to which the wound portion penetrating agent is applied can be obtained.
