Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a condom lubricant, and more particularly to a condom lubricant to which a fragrance component that makes rubber odor less sensitive is added, and a condom coated with the lubricant.

[0002]

2. Description of the Related Art Conventionally, in a condom made of latex rubber, the condom is molded, rolled up, and enclosed in a package together with a lubricant. Silicone oil is often used as a lubricant for the condom. As described above, a condom produced using latex rubber naturally produces rubber odor, but many users find this rubber odor unpleasant. Further, the rubber odor of a condom tends to become stronger with the lapse of time. For this reason, it is usually necessary to impart a strong fragrance even when adding a fragrance for the purpose of masking. However, especially in Japan, there is a general tendency to dislike the strong scent of condoms, and there is a strong tendency not to like them. From this point as well, it is desired to develop a technique for hiding the rubber odor of a condom, that is, effectively masking the rubber odor.

Among conventional condoms, for example, as in Japanese Patent Application No. 2001-220198, by adding tea polyphenol extracted from a plant to an aqueous lubricant, a bactericidal effect and a deodorizing effect associated with sterilization are exhibited. was there. However, since the deodorizing effect of this condom is associated with the bactericidal effect, the effect of masking the rubber odor of the condom was not so great.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional circumstances, and its object is to effectively prevent the rubber odor of a condom enclosed in a package together with a lubricant for a long period of time. A masking condom lubricant and a condom coated with this lubricant. At this time, generally-known masking is to conceal a specific odor by the odor of a fragrance, but in the case of the present invention, the condom lubricant and the condom using the lubricant are excessively contaminated. An object is to effectively reduce a specific rubber odor with a weakest fragrance (a small amount of fragrance) without causing a strong odor to be felt.

[0005]

In order to solve the above problems, the lubricant for a condom of the present invention comprises vanillin of 1 to 1000 ppm as a perfume ingredient added to a lubricant of a condom, for example, a silicone-based lubricant. , Or sandalwood oil (sandalwood) 100 to 2000 ppm, citronellol 100 to 1000 ppm, phenylethyl alcohol 10 to 1000 ppm, or cyclopentadecanolide 1 to 10 ppm. The fragrance component added to the lubricant masks the rubber odor of the condom and reduces the rubber odor strength to below a certain level. Moreover, the above-mentioned fragrance | flavor components are used 1 type or multiple types mixed. The attenuating property for weakening the rubber odor of a condom is expressed as the addition rate, which is the amount of the fragrance component necessary to reduce the rubber odor strength to a certain level or less.
The condoms according to claims 2 and 3 will be described together in the section of the embodiment of the invention.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to the drawings. 1 to 1 show a condom embodying the present invention. The condom a has a semen reservoir 2 protruding from the tip of the condom body 1, and the condom body a ′.
A mouthpiece 1 is formed at the opening edge on the base end side of the. For the condom a, the mouthpiece 3 is rolled up to be housed in the package b (FIG. 2), and the lubricant c added with the fragrance is dropped on the condom a (FIG. 3). Enclose inside. In this way, the condom a enclosed in the package b is in a state in which the dripped lubricant c permeates the entire surface and is applied. Note that the lubricant c attached to the condom a may be dropped before the condom a is rolled up.

As described above, the lubricant for a condom of the present invention has an effect of masking the rubber smell of the condom. However, it is not only to use a fragrance to eliminate the rubber odor of a condom, but not to feel a strong fragrance (without using a large amount of fragrance), a natural rubber latex with a weak fragrance (a small amount of fragrance). The purpose is to conceal the rubber odor of a condom made and effectively reduce it. The test results of the masking effect according to the present invention are shown in the following tables (1 type of fragrance) (2 types of fragrance mixed).

The evaluation of the masking effect is based on a sensory evaluation by a perfumer and the odor intensity scale of rubber odor is (0: odorless, 1: very weak, 2: weak, 3: normal, 4: strong, 5 :
From the above-mentioned purposes, the addition rate at which the rubber odor intensity is 2 or less and the odor intensity of the fragrance is 3 and preferably 2 or less is determined as the optimum addition rate.
A specific test method uses a silicone-based lubricant. Individual fragrances were added to this lubricant, and 100 mg of this lubricant was added to each product and the package was enclosed. And
A week later, the package was torn, the condom was rolled up and placed in a bottle, which the perfumer evaluated. The suitable amount of the lubricant to be applied (applied amount) per product to be enclosed in the package is about 100 mg, but the amount may be changed arbitrarily.

<Sensory evaluation by perfumer> ◎ ...
・ Rubber odor and fragrance are 2 or less. ○: rubber odor 2 or less, fragrance 3. △: rubber 3, flavor 3. ×: At least one of rubber odor and fragrance is 4 or more.
Blank is not added. In addition, the addition rate to the products in the table below is 10 lubricants for one product (condom).
It represents the concentration of each fragrance component with respect to the lubricant when 0 mg was added. Tables 1 to 1 show the cases where the flavors were added one by one. Tables 2 to 3 show the results when two kinds of fragrances were added.

[Table 2]

As a consideration based on the results of the sensory evaluation as described above, Tables 1 to 3 show. That is, vanillin, phenylethyl alcohol, cyclopentadecanolide, sandalwood oil, citronellol and above 5
In the case of various types of fragrances, any fragrance has the effect of concealing a specific rubber odor with the weakest fragrance and attenuating it, without making the fragrance feel a strong fragrance. As shown in Table 1 to, for these fragrances, the concentration showing a sufficient masking effect is 1 ppm or more for vanillin, 100 ppm or more for sandalwood oil, and 100 p for citronellol.
pm or more, phenylethyl alcohol was 10 ppm or more, and cyclopentadecanolide was 1 ppm or more. Also,
Concentrations of these fragrances that do not make you feel an excessively strong odor are vanillin 1000ppm or less, sandalwood oil 2000ppm or less, and citronellol 1000p.
pm or less, phenylethyl alcohol was 1000 ppm or less, and cyclopentadecanolide was 10 ppm or less. And among these fragrances, especially 1 of vanillin
