Description

Technical Field

[0001] The utility model belongs to the technical field of condoms and relates to a condom with a one-piece structure, in particular to a condom with an extruded one-piece structure. Background Art

[0002] At present, polyurethane is the main material for making ultra-thin condoms. Polyurethane can be used to make condoms with a thickness of 0.01mm. Hyaluronic acid lubricant is more refreshing and comfortable than traditional silicone oil. Therefore, some companies have begun to produce condoms containing hyaluronic acid lubricant. However, after long-term storage, polyurethane and hyaluronic acid may react chemically, affecting the performance and comfort of the condom. Therefore, existing condoms containing hyaluronic acid lubricant are usually made of latex, but ultra-thin condoms cannot be made with latex. The thickness is 0.03mm, which is difficult to meet people's demand for ultra-thin condoms.

[0003] In addition, there are also some condoms in the prior art that package additives separately from condoms. For example, Chinese utility model patent CN204581652U discloses a condom with independently packaged additives, which includes an outer packaging bag body, a condom body and an additive. The accommodating space in the outer packaging bag body is sealed and compressed and divided into multiple closed cavities. The condom body is sealed in one of the cavities, and the additive is sealed in the remaining cavities. It can change the current situation of the single function of existing condoms and avoid the risk of damaging the material structure of the condom when the additive amount is insufficient. However, when mixing the additive with the condom, it is necessary to take out the condom and the additive separately, and there is a risk of contamination during the operation. Moreover, this operation is relatively complicated and inefficient. In the case of insufficient light, it is easy for the additive to spill and be unable to mix with the condom, which makes its hygiene level and convenience relatively poor, and it is not convenient for promotion and application.

[0004] Therefore, in view of the defects existing in the above-mentioned prior art, it is necessary to develop a new type of condom with an extruded one-piece structure. Utility Model Content

[0005] In order to overcome the defects of the prior art, the utility model proposes a condom with an extruded one-piece structure, which not only solves the problem of chemical reaction between the polyurethane condom and the hyaluronic acid lubricant, but also improves comfort and ease of use.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A condom with an extruded one-piece structure, comprising an outer shell and a coating covering the outer shell, wherein a first groove and a second groove spaced apart from each other are provided in the outer shell, and wherein the outer shell is made of polystyrene, a polyurethane condom with a thickness of 0.01 mm is provided in the first groove, a hyaluronic acid lubricant is provided in the second groove, the coating is adhered to the outer shell and the openings of the first groove and the second groove are sealed by a hot-pressing periphery around the first groove and the second groove, the coating is also hot-pressed together with the outer shell by a hot-pressing spacing edge located between the first groove and the second groove, the hot-pressing spacing edge is in a pointed shape and the width of the hot-pressing periphery is greater than the width of the hot-pressing spacing edge, so that when the second groove is squeezed, the hyaluronic acid lubricant can break through the hot-pressing spacing edge and flow into the first groove to mix with the polyurethane condom.

[0008] Preferably, the height of the second groove gradually increases from a side close to the first groove to a side far from the first groove.

[0009] Preferably, a prefabricated cutting line is provided at one end of the shell, so that the shell can be broken through the prefabricated cutting line, thereby facilitating the tearing of the coating from the shell.

[0010] Preferably, the middle of the bottom of the first groove protrudes toward the inside of the first groove to form a bulge, and the bulge can cooperate with the sperm storage sac of the polyurethane condom.

[0011] Preferably, the coating is a PET composite aluminum film or a PE composite film.

[0012] Compared with the prior art, the condom with an extruded one-piece structure of the utility model has one or more of the following beneficial technical effects:

[0013] 1. The polyurethane condom used in the utility model can be thinner than the condom made of latex material, and the hyaluronic acid used as the lubricant is more refreshing and comfortable than the traditional silicone oil lubricant, thereby improving the comfort of the user when using the condom.

[0014] 2. The utility model stores the hyaluronic acid lubricant and the polyurethane condom separately, and squeezes the hyaluronic acid lubricant evenly into the condom by extrusion, thereby solving the problem of chemical reaction between hyaluronic acid and polyurethane and ensuring the quality and performance of the condom.

[0015] 3. The shell of the utility model is made of polystyrene, which is a hard shell material and has a certain degree of deformability. It can provide better protection and more convenient extrusion, is not easily affected by the external environment, is convenient for users to use and carry in daily life, and its one-piece structure is easy to operate, does not require additional support or fixation, and can release the hyaluronic acid lubricant by simply squeezing it.

[0016] 4. The utility model can help users easily identify and correctly select the wearing direction of condoms, which not only improves the convenience of user experience, but also enhances the safety during use.

[0017] 5. The extruded one-piece structure of the utility model allows the condom to remain in a closed state and combined with the hyaluronic acid. During the mixing process, fusion can be achieved without removing any part, which reduces the risk of contamination during operation. Moreover, the one-piece structure makes the operation simple and efficient. Even in low light conditions, users can use it easily, which improves the hygiene level and convenience.

[0018] 6. The extrusion structure design of the utility model is combined with ergonomics, with the left side lower and the right side higher, which not only provides a larger cavity space to store hyaluronic acid lubricant, but also increases the pressure generated during extrusion to ensure the smooth release of hyaluronic acid lubricant.

[0019] 7. The first groove and the second groove of the utility model adopt different shapes. This differentiated structural design can prevent the user from making incorrect operations during the squeezing process.

[0020] 8. The pointed hot-pressed spacing edge of the utility model can ensure that the condom remains sealed when not in use. This design not only improves the sealing of the package, but also the pointed shape design makes it convenient for users to squeeze and open it, while also effectively preventing the backflow of hyaluronic acid. Such innovative packaging technology not only ensures the hygiene and safety of the product, but also improves the user's convenience in operation.

[0021] 9. The utility model has a prefabricated cutting line on the shell, and the covering film can be easily peeled off by simply breaking off a small part of the shell, ensuring that it can be easily opened without additional tools. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] In order to solve the problem of chemical reaction between traditionally stored hyaluronic acid lubricants and polyurethane condoms, the utility model provides a condom with an extruded one-piece structure, which not only solves the problem of chemical reaction between the polyurethane condom and the hyaluronic acid lubricant, but also improves comfort and ease of use.

[0028] like Figure 1-3 As shown, the extruded one-piece condom of the utility model comprises an outer shell 1 and a covering film 2 covering the outer shell 1 .

[0029] The housing 1 is provided with a first groove 3 and a second groove 4 spaced apart from each other. A polyurethane condom 6 with a thickness of 0.01 mm is provided in the first groove 3. A hyaluronic acid lubricant 7 is provided in the second groove 4. Therefore, the polyurethane condom 6 used in the utility model can be thinner than a condom made of latex material, with a thickness of only 0.01 mm; and the use of hyaluronic acid as a lubricant is more refreshing and comfortable than traditional silicone oil lubricants, which improves the comfort of users when using condoms.

[0030] In the present invention, the coating 2 may be a PET composite aluminum film or a PE composite film. In this way, the coating 2 may be adhered to the housing 1 and the openings of the first groove 3 and the second groove 4 may be sealed by the heat-pressed periphery 9 around the first groove 3 and the second groove 4, thereby preventing the hyaluronic acid lubricant 7 from flowing out around the first groove 3 and the second groove 4.

[0031] The coating 2 is also heat-pressed with the housing 1 via a heat-pressed spacing edge 10 between the first groove 3 and the second groove 4. Thus, the first groove 3 and the second groove 4 are spaced apart, so that the hyaluronic acid lubricant 7 in the second groove 4 cannot flow to the polyurethane condom 6 in the first groove 3 under normal circumstances.

[0032] The heat-pressed spacing edge 10 is in a pointed shape and the width of the heat-pressed periphery 9 is greater than the width of the heat-pressed spacing edge 10. Since the width of the heat-pressed periphery 9 is greater than the width of the heat-pressed spacing edge 10, when the second groove 4 is squeezed, the hyaluronic acid lubricant 7 can break through the heat-pressed spacing edge 10 and flow into the first groove 3 to mix with the polyurethane condom 6, but cannot break through the heat-pressed periphery 9, and thus cannot flow out around the first groove 3 and the second groove 4, ensuring that the polyurethane lubricant 7 does not flow out.

[0033] Therefore, the utility model stores the hyaluronic acid lubricant 7 and the polyurethane condom 6 separately, and squeezes the hyaluronic acid lubricant 7 into the polyurethane condom 6 evenly by extrusion, thereby solving the problem of chemical reaction between hyaluronic acid and polyurethane, and ensuring the quality and performance of the condom. In addition, the extrusion-type one-piece structure of the utility model allows the polyurethane condom 6 to be combined with the hyaluronic acid lubricant 7 while maintaining a closed state, and the fusion can be achieved without taking out any part during the mixing process, thereby reducing the risk of contamination during the operation, and the one-piece structure makes the operation simple and efficient, and the user can easily use it even in low light conditions, thereby improving the hygiene level and convenience.

[0034] Moreover, since the hot-pressed spacing edge 10 is in a pointed shape, during squeezing, the hyaluronic acid lubricant 7 can only flow into the first groove 3 through the pointed portion protruding toward the first groove 7, so that after the hyaluronic acid lubricant 7 breaks through the hot-pressed spacing edge 10 and flows into the first groove 3, it cannot flow back into the second groove 4. Therefore, the hot-pressed spacing edge 10 in the pointed shape of the utility model can ensure that the condom remains sealed when not in use. This design not only improves the sealing of the package, but also the pointed shape design is convenient for users to squeeze and open, and effectively prevents the backflow of the hyaluronic acid lubricant. Such innovative packaging technology not only ensures the hygienic safety of the product, but also improves the user's operating convenience.

[0035] In the present invention, the shell 1 is made of polystyrene, which is a hard shell material and has a certain degree of deformability. Therefore, the shell 1 can provide better protection and more convenient squeezing, is not easily affected by the external environment, is convenient for users to use and carry in daily life, and its one-piece structure is easy to operate, does not require additional support or fixation, and can release the hyaluronic acid lubricant by simply squeezing it.

[0036] In addition, in the present utility model, if Figure 1 As shown in FIG. 1 , the height of the second groove 4 gradually increases from the side close to the first groove 3 to the side away from the first groove 3. Figure 1 and 2 As shown in , just squeeze along the arrow direction. Therefore, the extrusion structure design of the utility model combines ergonomics, with the left side lower and the right side higher, which not only provides a larger cavity space to store the hyaluronic acid lubricant 7, but also increases the pressure generated during squeezing, ensuring that the hyaluronic acid lubricant 7 can flow smoothly to the polyurethane condom 6.

[0037] Moreover, if Figure 3 As shown, the middle of the bottom of the first groove 3 protrudes toward the inside of the first groove 3 to form a protrusion 8. The protrusion 8 can cooperate with the sperm storage sac of the polyurethane condom 6, that is, the sperm storage sac of the polyurethane condom 6 can be sleeved on the protrusion 8. Therefore, the utility model can help users easily identify and correctly select the wearing direction of the polyurethane condom 6, which not only improves the convenience of user experience, but also enhances the safety during use. In addition, the first groove 3 and the second groove 4 of the utility model adopt different shapes. This differentiated structural design can prevent incorrect operation during the user's squeezing process, that is, the first groove 3 will not be mistakenly squeezed as the second groove 4 storing the hyaluronic acid lubricant 7.

[0038] Finally, in the present invention, a prefabricated cutting line 5 is provided at one end of the shell 1, so that the shell 1 can be broken by the prefabricated cutting line 5, thereby facilitating the removal of the cover 2 from the shell 1. Therefore, the present invention provides a prefabricated cutting line on the shell, and the cover can be easily uncovered by simply breaking off a small portion of the shell, ensuring that it can be easily opened without the need for additional tools.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Those skilled in the art can modify or replace the technical solution of the utility model according to the idea of ​​the utility model without departing from the essence and scope of the technical solution of the utility model.
