JPH09140739A - Condom from which air is removed - Google Patents

Abstract

PROBLEM TO BE SOLVED: To eliminate the laboriousness in removing the air in the projecting part at the front end of a condom and the failure associated therewith at the time of mounting the condom. SOLUTION: This condom is subjected to air removal in such a manner that the projecting part at its front part is flattened. After the condom is mounted at the penis in the form of closing the straight mouth part 4 on the rear surface of the projecting part, the oblate-like thin-film small piece 3 which is easily dissolved by a secretion to open a hole is extended there. As a result, the laboriousness of removing the air by squeezing the projecting part at the front end with the fingertip at the time of mounting is eliminated. Even a person handicapped on this fingers of one hand is able to mount the condom with his fingers of another hand. The small piece closing the straight mouth part 4 at the rear surface of the projecting part is easily ruptured at its central part by the movement of lowering the cylindrical part of the main body curved to a ring form at the time of mounting. The small piece is otherwise easily dissolved by the initial secretion or ejaculated sperm to make the path to ejaculate the sperm into the projection part.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a condom in which a convex portion at the tip is vented.

[0002]

2. Description of the Related Art Conventionally, a condom provided with a convex portion for collecting semen at the tip is deflated when used.
I had to wear it.

[0003]

SUMMARY OF THE INVENTION The present invention is to eliminate the trouble of air bleeding at the tip projection when a condom is attached.

[0004]

[Means for Solving the Problem] The problem is solved by developing an air venting product having a convex tip.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION According to the present invention, a small piece such as an oblate shape, in which a tip-shaped convex portion is formed flat during the manufacturing process and a single letter-shaped mouth is formed on the back surface of the convex portion where air is evacuated so that a hole is easily melted by body fluid To prevent the bulge due to the invasion of air into the convex portion due to the spread of the mouth.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the accompanying drawings.
As shown in FIG. 1, a flat thin film piece 3 for obstructing the one-letter shaped mouth portion 4 is attached from the back surface of the tip convex portion 2 which is formed flat and deflated as shown in FIGS.

[0007]

As described above, the product of the present invention eliminates the need for air venting for squeezing the tip convex portion with a fingertip when mounting, so that even if one of the fingers cannot be used, It can be worn only with the fingers. The small piece that closes the one-letter mouth on the back of the convex part can easily tear at the center part due to the action of the body cylinder part that is a ring-shaped curl when mounting, or the initial secretion liquid Alternatively, it can be easily dissolved by ejaculate to form an injection passage into the convex portion.
