Abstract
Description
Technical Field
[0001] This invention relates to the field of family planning products, and in particular to an isolation condom that is easy to manufacture and use. Background Technology
[0002] Condoms, as a common physical barrier for contraception and disease prevention, play an important role in public health and personal health protection. Traditional condoms are typically made of latex or similar elastic materials, with a hollow sheath structure that is closed at one end and open at the other, relying on their elasticity to fit snugly against the wearer's skin to achieve isolation. With technological advancements, various improved condoms have emerged on the market, such as ultra-thin, textured, or lubricated types, aiming to improve comfort or functionality. However, the vast majority of existing condoms still have exposed areas during use, failing to achieve complete isolation, especially at the edges where the sheath contacts the body or at the opening, which can increase the risk of bodily fluid exchange and disease transmission.
[0003] Existing isolation condoms suffer from structural design deficiencies, making it difficult to balance production feasibility and ease of use. For example, some published patents propose structures with additional isolation layers, but due to design complexity, high manufacturing requirements, or difficulty in cost control, they have not yet achieved commercialization. Furthermore, existing isolation condoms often require complex operating procedures during use, differing significantly from the simple wearing method of regular condoms, resulting in low user acceptance and difficulty in replacing existing products. Problems with existing structures also include: insecure fixation between the isolation membrane and the condom body, easy displacement or slippage during wear, inability to release lubricant simultaneously during wear, and unsmooth release of the roll-up structure. These issues not only affect the effectiveness of use but also limit their market penetration.
[0004] Therefore, there is an urgent need in this field to develop a contraceptive with a reasonable structure, easy production and convenient use, which can achieve more comprehensive physical isolation while maintaining a similar user experience to traditional condoms, and solve the technical problems of existing contraceptive structures in terms of fixation, lubrication and release and smoothness of wearing. Summary of the Invention
[0005] The purpose of this invention is to provide an isolation condom that is easy to manufacture and use, so as to solve the problems existing in the prior art.
[0006] To achieve the above objectives, the present invention provides the following solution: This invention provides an easy-to-manufacture and easy-to-use isolation condom, comprising an elastic condom body, which is an elastic hollow sheath closed at one end and open at the other. An isolation membrane is located on the outer side of the elastic condom body, and the isolation membrane has perforations. The diameter of the perforations is less than or equal to the diameter of the elastic condom body, and the thickness of the perforation edge of the isolation membrane is greater than the thickness of the isolation membrane itself. This membrane serves as a release support for the elastic condom body's folding spiral. The elastic condom body passes through the perforations in the isolation membrane from its closed end. The release support partially or completely wraps around the folding spiral of the elastic condom body. There is low-friction contact between the release support and the elastic condom body and the folding spiral. In use, the release support is held and applied towards the open end of the elastic condom body, causing the release support to push the folding spiral of the elastic condom body to release, thus completing the wearing of the elastic condom body.
[0007] Preferably, the cross-section of the release support is U-shaped, L-shaped, O-shaped, or elliptical.
[0008] Preferably, the release support is integrated with or separately from the isolation membrane.
[0009] Preferably, the isolation membrane may have a hollow liquid storage level near the perforation, and the liquid storage level has a liquid release hole near the edge of the perforation. When in use, the release support opens the rolled-up condom body, which will generate pressure, and the lubricant and other liquids will be squeezed and released from the hollow liquid storage level of the isolation membrane through the liquid release hole at the edge of the perforation to the outer surface of the condom body.
[0010] Preferably, the release support and the isolation membrane are made of the same material or different materials.
[0011] Preferably, a strength ring with a thickness greater than that of the isolation membrane is provided on the outer side of the isolation membrane.
[0012] Preferably, the open end of the release support of the isolation membrane is provided with a sealing member that can be opened and closed, so as to more stably fix the elastic condom body roll spiral.
[0013] Preferably, the isolation membrane is provided with reinforcing ribs to facilitate gripping or opening the isolation membrane.
[0014] Preferably, the release support is one or more stacked.
[0015] Preferably, the release support of the isolation membrane is located on the thicker part of the upper side of the folded spiral of the elastic condom body.
[0016] The present invention achieves the following beneficial technical effects compared to the prior art: This invention provides an easy-to-manufacture and easy-to-use isolation condom, characterized by its simple structure, convenient production, and high compatibility with traditional condoms in terms of user experience. The isolation membrane with a release support, combined with a folding spiral, achieves simultaneous unfolding and isolation during wear, effectively avoiding the exposure risks associated with traditional condoms. The release support wraps around the elastic condom's folding spiral, providing stability and preventing displacement during use. The lubricant reservoir and release hole automatically release lubricant during wear, enhancing comfort. The overall structure balances isolation effectiveness with production cost and ease of use, demonstrating promising market prospects. Attached Figure Description

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0022] The purpose of this invention is to provide an isolation condom that is easy to manufacture and use. It aims to achieve more complete physical isolation by optimizing the connection structure and release mechanism between the isolation film and the condom body, while maintaining a user experience similar to that of traditional condoms.
[0023] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0024] Example 1: Please see Figures 1 to 4 This invention provides an easy-to-manufacture and easy-to-use isolation condom. Its core lies in the integrated design of the isolation membrane and its release support structure, which simplifies the production process and optimizes the wearing process. The condom mainly includes an elastic condom body 1 (i.e., a hollow sheath) and an outer isolation membrane 2. The elastic condom body 1 is made of latex, polyurethane, or similar elastic materials, and has a traditional sheath shape with one end closed and the other open. During production, the open end is folded into a spiral 4 for easy unfolding.
[0025] The release liner 2 is made of a flexible thin film material and covers the outside of the elastic condom body 1. Its core structure is a centrally located perforation 21. The diameter of the perforation 21 is smaller than or equal to the diameter of the elastic condom body 1 to ensure that the release liner can effectively cover and isolate the outer surface of the condom. The key improvement of this invention is that the thickness of the release liner 2 is intentionally increased in the edge region of the perforation 21, forming a thickened structure with a specific shape surrounding the perforation. This structure is defined as the release support 3. In other words, the release support 3 is not an independent component, but is formed by thickening the release liner 2 material in a specific area. This greatly simplifies the number of parts and assembly steps, meeting the principle of "easy to manufacture".
[0026] The release support 3 is designed to partially or completely enclose the coiled spiral 4 of the elastic condom body 1. Specifically, the portion of the release support 3 located on the upper side of the coiled spiral 4 is its thickest part, and its cross-sectional shape can be designed as U-shaped, L-shaped, O-shaped, or elliptical according to manufacturing processes and functional requirements. For example, a U-shaped cross-section can better encircle the coiled spiral from both sides, an L-shaped cross-section may be more convenient for applying force from one side, while an O-shaped or elliptical shape can provide a more uniform circumferential enveloping force. The inner surface of the release support 3 has a low-friction contact with the outer surfaces of the elastic condom body 1 and the coiled spiral 4, which can be achieved by using a low-friction coefficient material or by applying a lubricating coating (such as silicone oil) to the contact surface, ensuring a smooth pushing process.
[0027] In use, users do not need to distinguish between parts like when operating complex instruments. They simply need to hold the release liner 2 and its integrally formed release support 3, just like holding the edge of a regular condom package, and then smoothly apply a push towards the opening of the elastic condom body 1. At this time, the release support 3, as the force transmission medium, will stably resist and push the folding spiral 4 with its thicker part, allowing it to gradually and smoothly unfold and release until the elastic condom body 1 is fully put on. This process can be completed with one hand, and the operation is highly similar to the traditional method of tearing open the packaging and squeezing out the condom, achieving the goal of "easy to use".
[0028] To further enhance structural stability and ease of grip, this invention provides several preferred solutions. The release support 3 and the release membrane 2 are preferably integrally injection molded or hot-pressed from the same material, which ensures structural strength and reduces production costs. Of course, when different performance requirements are needed (e.g., the release support requires higher stiffness), they can also be manufactured independently from different materials and then combined. A strength ring with a thickness greater than the main film can be provided around the periphery of the release membrane 2. This strength ring increases the overall stiffness of the release membrane, preventing wrinkles during gripping and pushing, and making force more concentrated and effective. Furthermore, radial or grid-like reinforcing ribs 5 can be provided on the surface of the release membrane 2. These reinforcing ribs 5 further enhance the overall strength of the membrane and provide users with a better grip and anti-slip effect.
[0029] To improve the wearing experience, in a preferred embodiment of the present invention, a hollow liquid reservoir is provided on the isolation membrane 2 near the perforation 21. This reservoir is pre-filled with a liquid such as lubricant, disinfectant, or health supplement. Tiny liquid release holes are provided at the edge of the reservoir near the perforation 21. The working principle is as follows: when the release support 3 is pushed by force to unfold the folding spiral 4, it will compress the liquid reservoir area enclosed within it. This compression forces the liquid in the reservoir to be squeezed out through the liquid release holes and directly applied to the outer surface of the unfolding elastic condom body 1, achieving simultaneous lubrication and wearing, thus improving the convenience and comfort of use.
[0030] To ensure the stability of the coiled spiral 4 during storage and transportation, the present invention can also provide an openable and closable sealing component at the open end of the release support 3. This component can be a simple hook and loop fastener, Velcro, or tearable connection point. After production and packaging, the sealing component is in the closed state, locking the coiled spiral 4 within the release support 3; in use, the user only needs to apply slight force to open the component, allowing the release process to proceed. This is particularly suitable for products requiring long-term storage or transportation.
[0031] Those skilled in the art will understand that the structure of the aforementioned release support 3 can be a continuous whole, or it can be composed of multiple independent thickened sections (i.e., multiple release supports) stacked or arranged side by side along the circumferential distribution of the perforation. Using a structure with multiple independent release supports can more flexibly adapt to sleeves of different sizes and reduce the requirements for mold precision during production.
[0032] In summary, this invention, through the synergistic effect of the isolation membrane, release support, and folding spiral, achieves more comprehensive physical isolation and a more convenient wearing experience while maintaining traditional condom usage habits.
[0033] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0034] It should be noted that the components mentioned in the above embodiments are all general standard parts or components known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.
[0035] This invention has illustrated its principles and implementation methods using specific examples. The descriptions of these embodiments are merely illustrative of the method and its core ideas; furthermore, those skilled in the art will recognize that modifications may be made to the specific implementation methods and application scope based on the principles of this invention. Therefore, the content of this specification should not be construed as limiting the invention.
