Abstract

The utility model relates to the field of medicine, in particular to contraception means used for preventing pregnancy and for protecting against sexually transmitted diseases. In the condom, comprising an elastic sheath 1, one end 2 of which is closed and the other end 3 of which is open, and also an auxiliary element 5 for spreading the elastic sheath as the condom, which is rolled up together with the elastic sheath 1 in a torus shape, is being put on, the auxiliary element 5 is in the form of a ring of elastic material, wherein the elastic sheath 1 is rolled up around the above-mentioned ring, the ring has a gap, and the ring comprises an element of reduced strength. This makes it convenient to put on the condom with one hand and also prevents misalignments of the condom as the latter is being put on.

Description

Condom

The utility model relates to the field of medicine, in particular to contraceptives used to prevent pregnancy and protect against sexually transmitted diseases.

State of the art

A condom is known that contains tapes, an elastic shell in the form of a cylinder, one end of which is deaf, and the other is rolled into a torus shape together with tapes, the free ends of which are connected with the possibility of breakage; in order to increase the reliability of the full deployment of the elastic shell and ensure its sterility, a protective shell is placed on the outside, while the free ends of the tapes are connected to it, SU 1797882 A1.

Before unfolding the elastic sheath, take the ends of the tapes and pulling them, unfold the elastic sheath, while the protective sheath is disconnected from the unstable solitary tape and is removed from the external surface of the elastic sheath together with the tape with which it is firmly connected.

This condom has an unreasonably complex design; a protective sheath designed to ensure sterility of the elastic sheath appears superfluous because the condom always contains sterile packaging.

A condom is known containing an elastic shell, in the manufacture of which the elastic shell is folded together with two separate strips of strong and very thin material in the shape of a torus. The ends of the strips protrude outward after coagulation of the elastic sheath and can be provided with elements for gripping them by hands, DE 4231077 A1. When putting on a condom, you must evenly pull on both strips.

However, this is not easy to implement in practice, because with an uneven force applied to the strips, the elastic condom of the condom is skewed when put on and even premature stretching of the strip. In addition, putting on a condom should be done with two hands, since it is impossible to pull both strips evenly and without skew with one hand; putting a condom with two hands is extremely inconvenient, since in this process one hand is usually used to fix the position of the penis.

This technical solution was made as a prototype of this utility model.

Disclosure of utility model The objective of the utility model is to ensure the convenience of putting on a condom with one hand, and also to eliminate its distortions when donning. According to a utility model, in a condom containing an elastic sheath, one end of which is deaf and the other open, and also an auxiliary element for expanding the elastic sheath when putting on the condom, folded together with an elastic sheath in the shape of a torus, the auxiliary element is made in the form of an elastic ring material, the elastic shell being folded around said ring; the ring is made with a gap; the ring includes an element of reduced strength.

The applicant has not identified sources containing information about technical solutions identical to this utility model, which allows us to conclude that it meets the criterion of "Novelty" ("N"). Brief Description of the Drawings

In the future, the utility model is illustrated by a detailed description of examples of its implementation with reference to the drawings, which show:

in FIG. 1 - elastic shell introduced into the auxiliary element before folding it together with the ring into a shape in the form of a torus; lengthwise cut;

in FIG. 2 — an elastic shell rolled up together with a ring in the shape of a torus;

in FIG. 3 is a section A-A in FIG. 3;

in FIG. 4 - auxiliary element in the form of a continuous ring, top view; in FIG. 5 - a ring made in accordance with paragraph 2 of the utility model formula with a gap;

in FIG. 6 - a ring made in accordance with paragraph 3 of the formula of a utility model with an element of reduced strength;

in FIG. 7 - a condom in the process of putting it on;

in FIG. 8 - a condom after putting it on.

The best embodiment of the utility model The condom contains an elastic shell 1, one end 2 of which is deaf and represents a small reservoir, and the other end 3 is open. The condom contains an auxiliary element for expanding the elastic membrane 1 when putting the condom on the penis; the auxiliary element is made in the form of a ring 5 of elastic material, in particular latex. Ring 5 in the initial (factory) position is rolled together with an elastic shell in the shape of a torus (Fig. 2, 3). Ring 5 to simplify its removal after putting on the condom can be made with a gap 6 (Fig. 5) or include an element of reduced strength 7 (Fig. 6). When putting on a condom, the elastic sheath rolled up together with the ring is straightened on the penis 4 (Fig. 7), pressing with one hand on the part of the elastic sheath 1 rolled up in the shape of a torus along with the ring 5. Ring 5 increases the diameter of the folded part of the elastic sheath 1, which simplifies and make it more convenient and quick to put it on the penis 4; in addition, ring 5 evenly transfers the force around the circumference of the put on elastic shell 1, which prevents its distortions in the process of donning.

After putting the condom on, the elastic sheath 1 and the ring 5 come to the position of FIG. 8. Then the ring 5 is easily removed, moving from the open end from the shell 1 to its blind end 2.

When making the ring 5 with a gap or with an element of reduced strength, it is removed by applying a force perpendicular to the longitudinal axis of the elastic shell 1.

Thus, the implementation of the features of the utility model provides a technical result, consisting in providing the possibility of putting it on with one hand and thereby increasing the convenience of its use; in addition, distortions of the elastic membrane when using a condom are practically eliminated.

Industrial applicability

The utility model does not require a change in the design of commercially available condoms; the auxiliary element (ring) for expanding the elastic shell can be made of the same material as the shell itself. According to the applicant, these circumstances are responsible for compliance with the utility model criterion "Industrial Applicability ^{^»} ( «IA»).
