Description

Technical Field

[0001] Reference to Related Applications This application claims priority to Chinese Patent Application No. CN202410467276.4 filed on April 18, 2024, and Chinese Patent Application No. CN202410729983.6 filed on June 6, 2024, and all the disclosed contents thereof are incorporated herein by reference.

[0002] This application relates to the technical field of underwear, and more specifically, to an adhesive brush with a replaceable adhesive body and a method of using the same.

Background Art

[0003] An adhesive brush is directly attached to the skin and is adhered to the skin during use. An adhesive layer is adhered to the inner surface of the adhesive brush. The adhesive layer is formed on the adhesive brush by manual adhesive brushing or transfer molding by hot melt. When the adhesive brush is used, the adhesive layer adheres to the skin, and when the adhesive brush is not used, the adhesive layer is covered with a release liner. If the adhesive brush is stored inappropriately after use, for example, if the release liner is not sufficiently adhered or the release liner is missing, impurities such as dust adhere to the adhesive layer, making it difficult to clean the adhesive layer and reducing the adhesive force. In addition, when the adhesive brush is used multiple times, the adhesive layer may become a breeding ground for bacteria that can have an adverse effect on human health.

[0004] To solve the above problem, existing technologies have produced products in which the adhesive bra and adhesive layer have a separate structure. That is, the adhesive bra and adhesive layer are independent products. During use, first the adhesive layer is attached to the adhesive bra, and then the adhesive layer of the combined adhesive bra and adhesive layer is attached to the skin. The inventor noticed the following: Since the adhesive bra is made of an elastic material and the adhesive layer is made of a colloidal material, both have a high degree of deformation. Therefore, it is difficult for a person to smoothly (also called flat) attach the adhesive layer to the adhesive bra during use, and as a result, the adhesive layer may wrinkle, fail to adhere completely to the skin, resulting in poor adhesion, an unpleasant user experience after adhesion to the skin, and poor comfort. [Overview of the Initiative] [Problems that the invention aims to solve]

[0013] In combination with the first embodiment, in possible embodiments, the adhesive bra with replaceable adhesive further comprises a pressure roller. The pressure roller is configured to roll and press the adhesive after the cup adhesive surface has adhered to the inner surface, or the pressure roller is configured to roll and press the molded cup after the inner surface has adhered to the cup adhesive surface.

[0014] In a second aspect, an embodiment of the present application provides a method for using an adhesive bra with replaceable adhesive. The method includes the following steps: Aligning the molded cup with the adhesive surface and adhering the outer surface to the adhesive surface; flattening the adhesive and adhering the cup's adhesive surface to the inner surface; removing the molded cup with the adhesive attached from the adhesive surface, adjusting the shape of the molded cup, and attaching the adhesive to the breast; and after the use of the adhesive bra with replaceable adhesive is complete, removing the molded cup and detaching the adhesive from the molded cup.

[0015] In a third aspect, an embodiment of the present application provides another method of using the adhesive bra with replaceable adhesive.

In this way, the adhesive body can be artificially and quickly and smoothly adhered to the inner surface, and wrinkles in the adhesive body can be prevented. Alternatively, the protective surface of the adhesive body can be adhered to the adhesive surface, and the adhesive body can be fixed and limited in position by the positioning body, preventing it from shifting or moving, and preventing wrinkles. In this way, the molded cup can be artificially and quickly and smoothly adhered to the cup adhesive surface. During use of the replaceable adhesive bra, the combination of the molded cup and adhesive body is removed from the adhesive surface, and the adhesive body is attached to the breast. Because the adhesive is wrinkle-free, it can be completely attached to the breast, ensuring adhesion and comfort during use.

[0017] In the adhesive bra with replaceable adhesive provided in this embodiment, the molded cup and adhesive can be reused multiple times, making them environmentally friendly and cost-effective. Furthermore, when not in use, the molded cup and adhesive are packaged separately, preventing bacterial growth and being more beneficial to human health.

[0018] This application provides a first method of using an adhesive bra with a replaceable adhesive. Compared to existing technologies, before using the adhesive bra with a replaceable adhesive, the outer surface of the molded cup is adhered to the adhesive surface, fixing the shape and position of the molded cup so that the inner surface can be flat or a fixed curved surface that protrudes slightly upward. Then, the adhesive surface of the cup can be quickly adhered to the inner surface. This simplifies the adhesion operation, saves time, and improves operational efficiency. It also prevents wrinkles in the adhesive, ensures adhesion during use, and improves comfort performance. At the same time, the adhesive can be replaced by the user, making it environmentally friendly and beneficial to human health.

[0019] This application provides a second method of using an adhesive bra with a replaceable adhesive.

Next, the inner surface of the molded cup can be quickly attached to the cup adhesive surface. This simplifies the adhesive operation, saves time during the adhesive operation, improves operational efficiency, ensures adhesiveness during use, and improves comfort performance. At the same time, the adhesive can be replaced by the user, making it environmentally friendly and beneficial to human health. [Brief explanation of the drawing]

Mode for Carrying Out the Invention

[0021] In order to more clearly illustrate the technical problems to be solved, the technical solutions, and the beneficial effects of the present application, the present application will be described in more detail below with reference to the drawings and embodiments. It should be noted that the specific embodiments described in this specification are only used to explain the present application and are not used to limit the present application.

[0022] Referring to FIGS. 1 to 4 together, an adhesive brush with a replaceable adhesive body provided in the present application will be described. The adhesive brush with a replaceable adhesive body includes a molded cup 1, an adhesive body 3, and a positioning body 2. The molded cup 1 is made of an elastic material and has an outer surface 11 and an inner surface 12 provided opposite to each other. The adhesive body 3 has a cup-adhesive surface 311 and a protective surface 341 provided opposite to each other, and the cup-adhesive surface 311 is adhered to the inner surface 12. The positioning body 2 has an adhesive surface 21, and the positioning body 2 is configured to fix the shape and limit the position of the molded cup 1 or the adhesive body 3. <000009​The outer surface 11 is adhered to the adhesive surface 21, fixing the shape and limiting the position of the molded cup 1, and the cup adhesive surface 311 is adhered to the inner surface 12. Alternatively, the protective surface 341 is adhered to the adhesive surface 21, fixing the shape and limiting the position of the adhesive body 3, and the inner surface 12 is adhered to the cup adhesive surface 311.

[0024] The molded cup 1 is generally a circular sheet-like structure, or a substantially circular sheet-like structure. After the molded cup 1 is manufactured and molded, the central part of the molded cup 1 protrudes relative to the outer edge. When molding or designing the molded cup 1, the outer surface 11 can be formed as a curved surface and the inner surface 12 can be formed as a flat surface.

[0025] During use of the molded cup 1, since the molded cup 1 is made of an elastic material (e.g., solid silica gel, liquid silica gel, or thermoplastic elastomer) and is flexible and deformable, the molded cup 1 can be deformed so that its inner surface 12 becomes a concave curved surface, and can conform to the structure of a human breast.

[0026] The mold cup 1 may be used individually, as shown in Figure 1, or in combination of two mold cups 1. As shown in Figure 4, when two mold cups 1 are used in combination, the two mold cups 1 are connected via an intermediate connecting sheet 13, and the intermediate connecting sheet 13 and the two mold cups 1 are molded together. Regardless of whether one mold cup 1 is used individually or two mold cups 1 are used in combination, the shape of each mold cup 1 is fixed by the positioning body 2, and each mold cup 1 is attached to the skin via the adhesive body 3.

[0027] The adhesive body 3 is mainly made of adhesive material, and the adhesive surface 311 of the cup of the adhesive body 3 is adhesive. The adhesive body 3 has a certain thickness because it needs to adhere to the skin of the breast. Also, to simplify the manufacturing process, the adhesive body 3 generally has a sheet-like structure, and the surface of the sheet-like structure is flat. The adhesive body 3 and the molded cup 1 are separate structures; that is, the adhesive body 3 and the molded cup 1 are manufactured and packaged independently. When the adhesive body 3 and the molded cup 1 are not in use, the adhesive body 3 and the molded cup 1 are kept separately. Before the adhesive body 3 and the molded cup 1 are used, the adhesive body 3 is adhered to the inner surface 12.

[0028] Since the mold cup 1 itself is flexible and deformable, and the adhesive body 3 is also deformable, when the adhesive body 3 is directly adhered to the inner surface 12, on the one hand, it is not easy for the inner surface 12 to make complete contact with the planar adhesive body 3, and many small gaps exist between them. On the other hand, because the mold cup 1 itself is flexible, when the adhesive body 3 is about to adhere, even if the mold cup 1 is placed on a flat table, a person must apply force to the mold cup 1, resulting in the mold cup 1 deforming and shifting position, making it difficult for the adhesive body 3 to perfectly conform to the mold cup 1, thus increasing the adhesion time and complexity of the adhesion operation. To prevent deformation of the mold cup 1 or the adhesive body 3, the positioning body 2 is configured to fix the shape of the mold cup 1 or the adhesive body 3 and to position it.

[0029] Specifically, the mold cup 1 and the adhesive body 3 can be positioned and then the adhesion operation can be performed. For example, first, the mold cup 1 and the adhesive surface 21 are aligned, and the outer surface 11 is adhered to the adhesive surface 21, thereby fixing and restricting the position of the mold cup 1 so that it cannot move. In this case, the inner surface 12 can be maintained as a flat surface or as a slightly protruding curved surface. Next, the adhesive body 3 with a flat structure is adhered to the inner surface 12. Since the mold cup 1 is made of an elastic material (e.g., solid silica gel, liquid silica gel, or thermoplastic elastomer) and has a certain degree of elasticity, it is possible to ensure that the outer surface 11 is completely adhered to the adhesive surface 21.

[0030] Compared to adhesion between a surface with an unfixed shape and a flat surface, when the flat cup adhesive surface 311 is adhered to the fixed-shape inner surface 12, the cup adhesive surface 311 adheres completely to the inner surface 12 without any gaps, ensuring that the adhesive body 3 does not wrinkle. Furthermore, since the positioning body 2 restricts the position of the molded cup 1, even if force is applied to the molded cup 1 during the adhesion operation, the positioning body 2 can limit the deformation of the molded cup 1. Therefore, the adhesive body 3 can be quickly adhered to the inner surface 12, simplifying the adhesion operation, saving time during the adhesion operation, and improving operational efficiency.

[0031] For example, first, the adhesive body 3 and the adhesive surface 21 are aligned, and the protective surface 341 is adhered to the adhesive surface 21. That is, the adhesive body 3 is fixed in place so that it cannot move, and its position is restricted. Because the adhesive body 3 has a sheet-like structure, it is possible to ensure that the cup adhesive surface 311 is kept flat. Next, the outer surface 11 of the molded cup 1 is adhered to the cup adhesive surface 311.

[0032] Furthermore, the protective surface 341 is not adhesive, and after the adhesive body 3 is attached to the positioning body 2, the protective surface 341 can be removed from the adhesive surface 21 by manual operation. The adhesive body 3 further has a skin attachment surface 321 below the protective surface 341. Since the skin attachment surface 321 is adhesive, after the protective surface 341 is peeled off, the skin attachment surface 321 can be attached to the breast.

[0033] Since the shape of the molded cup 1 is slightly larger than the shape of the adhesive body 3, it is preferable to first fix the molded cup 1 to the positioning body 2, and then adhere the adhesive body 3 to the inner surface 12, in order to facilitate user operation.

[0034] The positioning body 2, molded cup 1, and adhesive body 3 are separate components; that is, the positioning body 2, molded cup 1, and adhesive body 3 are manufactured and packaged independently. When the positioning body 2, molded cup 1, and adhesive body 3 are not used, they are placed separately. When the positioning body 2, molded cup 1, and adhesive body 3 are used, either the molded cup 1 or the adhesive body 3 is attached to the adhesive surface 21. The positioning body 2, adhesive body 3, and molded cup 1 are sold together.

[0035] During the adhesion process, the positioning body 2 may be made of a rigid material and must have a certain hardness in order to support the molded cup 1 or adhesive body 3 and prevent deformation of the molded cup 1 or adhesive body 3. To form the adhesive surface 21, an adhesive layer is applied to the positioning body 2, and the applied adhesive layer is very thin. The adhesive layer is adhesive and hard. Since the adhesive layer is applied to the positioning body 2 and does not deform arbitrarily, the molded cup 1 made of an elastic material can be adhered to it, or the non-adhesive protective surface 341 can be adhered to it. The molded cup 1 made of an elastic material can be separated from the adhesive layer by an external force such as being pulled off by a person, and the protective surface 341 can be separated from the adhesive layer.

[0036] As the positioning body 2, a fixed colloid with a fixed shape (for example, a thick double-sided adhesive tape) can be directly used, with one side of the adhesive colloid being the adhesive surface 21. The colloid may be attached to a flat table surface or a flat platform, and the mold cup 1 or adhesive body 3 is fixed in place by the adhesive method. Since the fixed colloid does not deform arbitrarily, the mold cup 1 made of an elastic material can be adhered to it, and the non-adhesive protective surface 341 can also be adhered to it. The mold cup 1 made of an elastic material can be separated from the colloid by an external force such as being pulled off by a person, and the protective surface 341 can be separated from the colloid.

[0037] Compared to existing technologies, in the replaceable adhesive bra provided in this application, the positioning body 2 can fix the shape and restrict the position of the molded cup 1 or the adhesive body 3. Before using the replaceable adhesive bra, the outer surface 11 of the molded cup 1 can be adhered to the adhesive surface 21, thereby fixing and restricting the position of the molded cup 1 by the positioning body 2, preventing it from shifting or moving. In this way, the adhesive body 3 can be artificially and quickly and smoothly adhered to the inner surface 12, preventing wrinkles from forming on the adhesive body 3. Alternatively, the protective surface 341 of the adhesive body 3 can be adhered to the adhesive surface 21, fixing and restricting the position of the adhesive body 3 by the positioning body 2, preventing it from shifting or moving, and preventing wrinkles. In this way, the molded cup 1 can be artificially and quickly and smoothly adhered to the cup adhesive surface 311. During use of the replaceable adhesive bra, the combination of the molded cup 1 and the adhesive body 3 is removed from the adhesive surface 21, and the adhesive body 3 is attached to the breast. Because the adhesive body 3 is wrinkle-free, it can be completely attached to the breast, ensuring adhesion and comfort during use.

[0038] In the adhesive bra with replaceable adhesive provided in this embodiment, the molded cup 1 and adhesive 3 can be reused multiple times, making them environmentally friendly and cost-effective. Furthermore, when not in use, the adhesive 3, molded cup 1, and positioning body 2 are packaged separately, preventing bacterial growth and being more beneficial to human health.

[0039] In some embodiments, the adhesive body 3 may have a structure as shown in Figure 5. Referring to Figure 5, the adhesive body 3 comprises an adhesive body and a first release liner 34. One surface of the adhesive body is a cup adhesive surface 311, and the other surface of the adhesive body is a skin adhesion surface 321. One surface of the first release liner 34 is adhered to the skin adhesion surface 321, and the other surface of the first release liner 34 is a protective surface 341.

[0040] Both the cup adhesive surface 311 and the skin contact surface 321 are adhesive. The cup adhesive surface 311 is used to adhere to the inner surface 12, and the skin contact surface 321 is used to adhere to the breast. The first release liner 34 itself is not adhesive, but it has hardness and can maintain a flat state. The first release liner 34 covers the skin contact surface 321 to protect it. This prevents impurities from adhering to the skin contact surface 321 before it adheres to the skin, ensuring adhesion and comfort during use.

[0041] Before the adhesive body 3 is adhered, the first release liner 34 is attached to the skin contact surface 321, and the hardness of the first release liner 34 itself helps to keep the entire adhesive body 3 flat, thereby further ensuring that the adhesive body 3 adheres to the mold cup 1 without any gaps. After removing the combination of the adhesive body 3 and the mold cup 1 from the positioning body 2, the first release liner 34 is peeled off so that the skin contact surface 321 is exposed.

[0042] Since the adhesive body 3 and the molded cup 1 are manufactured and packaged independently, they are stored separately when not in use. To ensure the tackiness of the cup adhesive surface 311, a second release liner can be attached to the cup adhesive surface 311.

[0043] In some embodiments, the adhesive body may have a structure as shown in Figure 5. Referring to Figure 5, the adhesive body comprises, in order, a first adhesive layer 31, an intermediate elastic layer 33, and a second adhesive layer 32, the outer surface of the first adhesive layer 31 being a cup adhesive surface 311, and the outer surface of the second adhesive layer 32 being a skin adhesion surface 321.

[0044] The first adhesive layer 31 is configured to adhere to the inner surface 12, and the second adhesive layer 32 is configured to adhere to the skin. Preferably, the first adhesive layer 31 is a pressure-sensitive adhesive layer, which has good adhesive performance and peel strength, making it suitable for adhering to the mold cup 1, and which is less likely to fall off or shift position after adhesion. The second adhesive layer 32 is a silicone gel layer, which is made of a silicone gel with relatively low peel strength, so does not cause pain to the user when peeled off. Multiple small pores can be provided in the silicone gel layer to improve moisture permeability and breathability and to make adhesion more comfortable.

[0045] The intermediate elastic layer 33 is used as a substrate to which the first adhesive layer 31 and the second adhesive layer 32 are applied, thereby making the adhesive body 3 easier to mold. Since the intermediate elastic layer 33 can also support the first adhesive layer 31 and the second adhesive layer 32 as a substrate, the entire adhesive body 3 can be peeled off from the mold cup 1, ensuring the reuse of the mold cup 1 and the adhesive body 3.

[0046] Furthermore, the intermediate elastic layer 33 must have waterproof and breathable properties and must not cause any damage to human skin.

[0047] Preferably, the intermediate elastic layer 33 is made of cloth or a film material such as a silicone rubber film or a polyurethane (PU) film. Because the intermediate elastic layer 33 itself is elastic and the formed laminated structure is shrinkable and stretchable, the entire adhesive body 3 is shrinkable and stretchable.

[0048] Specifically, before adhering the adhesive body 3 to the molded cup 1, the adhesive body 3 is first flattened. Because the intermediate elastic layer 33 is stretchable, when the adhesive body 3 is artificially flattened, the intermediate elastic layer 33 stretches, and the first adhesive layer 31 also stretches. In this way, the cup adhesive surface 311 can be completely attached to the inner surface 12. After the adhesive body 3 is attached, the combination of the molded cup 1 and the adhesive body 3 is removed from the adhesive surface 21, the molded cup 1 is no longer restricted in position, and the molded cup 1 is restored to its structure in use. In this case, the molded cup 1 deforms the adhesive body 3. Because the intermediate elastic layer 33 is shrinkable and stretchable, after the intermediate elastic layer 33 changes from a flat surface to a curved surface, the portion of the intermediate elastic layer 33 to which the first adhesive layer 31 is applied can stretch, and the portion of the intermediate elastic layer 33 to which the second adhesive layer 32 is applied can contract. Thus, the first adhesive layer 31 stretches and the second adhesive layer 32 contracts. Therefore, the adhesive body 3 can conform to the concave curved surface of the inner surface 12 during use of the mold cup 1, and there are no wrinkles on the skin contact surface 321.

[0049] In some embodiments, after the cup adhesive surface 311 is adhered to the inner surface 12, the outer edge of the adhesive body 3 does not extend beyond the outer edge of the molded cup 1.

[0050] In one embodiment, the outer edge of the adhesive body 3 overlaps with the outer edge of the molded cup 1, ensuring that the back surface of the molded cup 1 is completely adhered to the breast, thereby securing the contact area between the molded cup 1 and the breast, and improving the adhesive strength between the molded cup 1 and the breast. At the same time, the protective effect of the molded cup 1 on the breast is ensured, preventing breast exposure.

[0051] In another embodiment, the outer edge of the molded cup 1 extends beyond the outer edge of the adhesive 3; in other words, the adhesive 3 does not completely cover the molded cup 1. This ensures the positioning of the breast and the molded cup 1 while reducing the area of ​​adhesion between the molded cup 1 and the breast, avoiding discomfort for the wearer and optimizing the wearing experience. In this case, breast exposure can also be avoided, as long as the wearer's breasts fit the size of the molded cup 1.

[0052] In some embodiments, the positioning body 2 may have a structure as shown in Figures 1, 2, and 6. Referring to Figures 1, 2, and 6, the positioning body 2 is an adhesion device, the adhesion device has a cavity, the cavity structure of the cavity conforms to the shape and thickness of the mold cup 1, and the cavity wall of the cavity is an adhesive surface 21.

[0053] The adhesion device may be made of a hard material and have a certain hardness. The adhesion device can be considered as a flat plate, and one side of the flat plate is provided with a downwardly recessed cavity. The cavity is used to fix the shape and position of the mold cup 1 or the adhesive 3, and is particularly used to fix the shape and position of the mold cup 1. Because the cavity structure of the cavity conforms to the external shape of the mold cup 1, after the mold cup 1 is artificially placed inside the cavity, the cavity can restrict the state of the mold cup 1, the inner surface 12 can be kept flat, and adhesion between the planar adhesive 3 and the inner surface 12 can be facilitated.

[0054] Specifically, the molded cup 1 has an uneven thickness structure. Preferably, in order to conform to the shape of the breast, the thickness of the molded cup 1 gradually decreases from the center point towards the outer edge. That is, the thickness is greatest at the center point of the molded cup 1, and the thickness is smallest at the outer edge of the molded cup 1.

[0055] After the molded cup 1 is manufactured and molded, the central part of the molded cup 1 protrudes relative to the outer edge. Furthermore, when molding or designing the molded cup 1, the outer surface 11 can be formed as a curved surface and the inner surface 12 as a flat surface. Since the molded cup 1 is manufactured from an elastic material (e.g., solid silica gel, liquid silica gel, or thermoplastic elastomer), it is flexible and deformable, and can be deformed during use. Therefore, the inner surface 12 can be made into a concave curved surface to conform to the shape of a human breast.

[0056] By designing the mold cup 1 with an uneven thickness, the degree of deformation of the outer surface 11 can be reduced. Furthermore, since the cavity structure of the cavity is suited to the shape and thickness of the mold cup 1, after the mold cup 1 is positioned within the cavity, the inner surface 12 may be flat, and the outer surface 11 may still be curved, as shown in Figure 6. This facilitates the adhesion operation of the adhesive body 3 in the next step.

[0057] Furthermore, the cavity structure of the cavity is adapted to the shape and thickness of the mold cup 1, so the depth of each point in the cavity is not equal. The cavity wall of the cavity, i.e., the adhesive surface 21, is an arcuate surface. Compared to a planar structure, the arcuate surface structure has many positional restricting directions, so when the adhesive body 3 is attached, the mold cup 1 can be restricted in multiple directions.

[0058] Because the positioning body 2 has only a cavity, it has a simple structure, is easy to manufacture, and has low manufacturing costs. Compared to the method in which the adhesive body 3 is formed on the mold cup 1 by manual adhesive brushing or hot melt, the replaceable adhesive brush provided in this embodiment can be used repeatedly and has lower usage costs. In addition, when the replaceable adhesive brush is not used, the adhesive body 3 is packaged separately, so bacteria do not grow and it is more beneficial to human health.

[0059] In addition to being used to restrict the position of the molded cup 1, the cavity can also be used to restrict the position of the adhesive body 3. Since the adhesive body 3 has a planar structure of uniform thickness, after the adhesive body 3 adheres to the cavity, it becomes a curved structure of uniform thickness, and the curved shape of the cup adhesive surface 311 conforms to the curved shape of the adhesive surface 21, that is, it can conform to the curved shape of the outer surface 11, thereby making it easier for the molded cup 1 to adhere to the adhesive body 3.

[0060] In another embodiment, the positioning body 2 is an adhesion device, the adhesion device has no cavity, and the adhesion device is a flat plate. An adhesive layer is applied directly to the surface of the adhesion device to form an adhesive surface 21. The adhesive surface 21 is coplanar with the outer surface of the adhesion device; in other words, the outer surface of the adhesion device can form an adhesive surface 21.

[0061] In some embodiments, the molded cup 1, adhesive body 3, and positioning body 2 may have the structure shown in Figure 3. Referring to Figure 3, the molded cup 1 is provided with a first breathable hole 14, and the adhesive body 3 is provided with a second breathable hole 35. A positioning post 211 is provided on the adhesive surface 21. For positional constraint, the positioning post 211 is inserted into the first breathable hole 14 and the second breathable hole 35.

[0062] The molded cup 1 is provided with a plurality of first ventilation holes 14, and the adhesive body 3 is provided with a plurality of second ventilation holes 35. During the design and manufacturing stages of the molded cup 1 and the adhesive body 3, the positions of the plurality of first ventilation holes 14 correspond one-to-one with the positions of the plurality of second ventilation holes 35. Both the first ventilation holes 14 and the second ventilation holes 35 are used for ventilation, ensuring the breathability of the adhesive bra.

[0063] Since the molded cup 1 and the adhesive body 3 are manufactured separately and packaged independently, positioning posts 211 are further provided on the adhesive surface 21 to ensure that the multiple first ventilation holes 14 and the multiple second ventilation holes 35 correspond one-to-one after the molded cup 1 and the adhesive body 3 are adhered together. When the outer surface 11 of the molded cup 1 is adhered to the adhesive surface 21, the positioning posts 211 penetrate the first ventilation holes 14, and when the cup adhesive surface 311 of the adhesive body 3 is adhered to the inner surface 12, the positioning posts 211 further penetrate the second ventilation holes 35. Similarly, if the adhesive body 3 is adhered first, the positioning posts 211 penetrate the second ventilation holes 35 and then the first ventilation holes 14. By providing the positioning posts 211, it is possible to ensure that the first ventilation holes 14s and the second ventilation holes 35 correspond axially.

[0064] The number of first ventilation holes 14 is greater than the number of positioning posts 211. Preferably, there are three positioning posts 211. Although only three first ventilation holes 14 and three second ventilation holes 35 are shown in Figure 3, the number is not limited to three.

[0065] In some embodiments, the adhesive bra with replaceable adhesive may have a structure as shown in Figure 1. Referring to Figure 1, the adhesive bra with replaceable adhesive further comprises a pressure roller 4. The pressure roller 4 is configured to roll and press the adhesive 3 after the cup adhesive surface 311 has adhered to the inner surface 12, or the pressure roller 4 is configured to roll and press the molded cup 1 after the inner surface 12 has adhered to the cup adhesive surface 311.

[0066] After manually attaching the adhesive 3 to the mold cup 1, the protective surface 341 or outer surface 11 can be manually rolled and pressed using the pressure roller 4. This pushes out small air bubbles between the adhesive 3 and the mold cup 1, further improving the adhesion between the adhesive 3 and the mold cup 1.

[0067] The pressure roller 4 and the positioning body 2 may be packaged together or separately. The pressure roller 4 may be sold together with the positioning body 2, the adhesive body 3, and the mold cup 1.

[0068] Based on the same inventive concept, embodiments of this application further provide a method for using an adhesive bra in which the adhesive body is replaceable. This method includes the following steps:

[0069] S1: Align the mold cup 1 with the adhesive surface 21 and adhere the outer surface 11 to the adhesive surface 21.

[0070] S2: Flatten the adhesive body 3 and adhere the cup adhesive surface 311 to the inner surface 12.

[0071] S3: Remove the mold cup 1 to which the adhesive body 3 is attached from the adhesive surface 21, adjust the shape of the mold cup 1, and attach the adhesive body 3 to the breast.

[0072] S4: After use of the adhesive bra with replaceable adhesive, remove mold cup 1 and remove adhesive 3 from mold cup 1.

[0073] The positioning body 2, mold cup 1, and adhesive body 3 are separate components; that is, they are manufactured and packaged independently. When the positioning body 2, mold cup 1, and adhesive body 3 are not used, they are stored separately. When used, the mold cup 1 is attached to the adhesive surface 21. The positioning body 2, adhesive body 3, and mold cup 1 are sold together. Multiple adhesive bodies 3 can be attached to a single mold cup 1. When the viscosity of the adhesive body 3 decreases, it can be replaced with a new adhesive body 3.

[0074] Because the mold cup 1 itself is flexible and deformable, when the adhesive 3 is directly adhered to the inner surface 12, on the one hand, it is not easy for the inner surface 12 to make complete contact with the planar adhesive 3, and many small gaps exist between them. On the other hand, because the mold cup 1 itself is flexible, force must be applied to the mold cup 1 when the adhesive 3 is about to adhere to it, resulting in the mold cup 1 deforming, making it difficult for the adhesive 3 to fully conform to the mold cup 1, thus increasing the adhesion time and complexity of the adhesion operation. To prevent deformation of the mold cup 1, the positioning body 2 is configured to fix the shape of the mold cup 1 and position it.

[0075] Specifically, in step S1, by aligning the mold cup 1 and the adhesive surface 21 and adhering the outer surface 11 to the adhesive surface 21, the inner surface 12 can be maintained as a flat surface or as a curved surface that slightly protrudes from the adhesive surface 21.

[0076] In step S2, compared to adhesion between a surface with an unfixed shape and a flat surface, when the flat adhesive body 3 is adhered to the inner surface 12 with a fixed shape, the cup adhesive surface 311 adheres completely to the inner surface 12 without any gaps, ensuring that the adhesive body 3 does not wrinkle. Furthermore, in step S2, even if force is applied to the molded cup 1, the positioning body 2 can limit the deformation of the molded cup 1. Therefore, the adhesive body 3 can be quickly adhered to the inner surface 12.

[0077] Furthermore, in step S2, after manually adhering the adhesive body 3 to the inner surface 12, small air bubbles between the adhesive body 3 and the mold cup 1 can be pushed out by pressing the adhesive body 3 or rolling and pressing the adhesive body 3 with the pressure roller 4.

[0078] This application provides a method for using an adhesive bra with a replaceable adhesive. Compared to existing technologies, before using the adhesive bra with a replaceable adhesive, the outer surface 11 of the molded cup 1 is adhered to the adhesive surface 21, fixing the shape and limiting the position of the molded cup 1, so that the inner surface 12 can be flat or a fixed curved surface that protrudes slightly toward the adhesive surface 21. Next, the cup adhesive surface 311 of the adhesive 3 can be quickly adhered to the inner surface 12. This simplifies the adhesion operation, saves time, and improves operational efficiency. It also prevents wrinkles in the adhesive 3, ensures adhesion during use, and improves comfort performance. At the same time, the adhesive 3 can be replaced by the user, making it environmentally friendly and beneficial to human health.

[0079] Furthermore, since the positioning body 2 has only an adhesive surface 21, its structure is simple, manufacturing is easy, and manufacturing costs are low. Compared to the method in which the adhesive body 3 is formed on the mold cup 1 by manual adhesive brushing or hot melt, the method of using the replaceable adhesive brush provided in this embodiment allows the mold cup 1 and adhesive body 3 to be reused multiple times, resulting in lower usage costs. In addition, if the replaceable adhesive brush is not used, the adhesive body 3 is packaged separately, preventing bacterial growth and being more beneficial to human health.

[0080] In some embodiments, the adhesive body 3 comprises an adhesive body and a first release liner 34. One surface of the adhesive body is a cup adhesive surface 311, and the other surface of the adhesive body is a skin adhesion surface 321. One surface of the first release liner 34 is adhered to the skin adhesion surface 321, and the other surface of the first release liner 34 is a protective surface 341. The first release liner 34 has a planar structure.

[0081] Specifically, step S3 includes the following: removing the mold cup 1 to which the adhesive body 3 is attached from the adhesive surface 21, peeling the first release liner 34 from the skin contact surface 321, adjusting the shape of the mold cup 1, and attaching the skin contact surface 321 to the breast.

[0082] The first release liner 34 itself has hardness and can maintain a flat state. Before step S1, the first release liner 34 is attached to the skin contact surface 321, and the hardness of the first release liner 34 itself allows the entire adhesive body 3 to be maintained in a flat state. In step S2, it is further ensured that the adhesive body 3 adheres to the mold cup 1 on the adhesive surface 21 without any gaps. After the adhesive body 3 is attached, the first release liner 34 is peeled off.

[0083] In some embodiments, before step S1 and / or after step S4, the method further includes: washing the mold cup 1 to keep it clean and ready for convenient reuse, and removing any residual colloid adhering to the inner surface 12.

[0084] If mold cup 1 is washed before step S1, the washed mold cup 1 must be dried before proceeding to step S1.

[0085] Based on the same inventive concept, this embodiment further provides another way of using an adhesive bra with a replaceable adhesive body. The adhesive body 3 comprises an adhesive body and a first release liner 34. One surface of the adhesive body is the cup adhesive surface 311, and the other surface of the adhesive body is the skin adhesion surface 321. One surface of the first release liner 34 is adhered to the skin adhesion surface 321, and the other surface of the first release liner 34 is the protective surface 341. This method of use includes the following steps.

[0086] S1: Align the adhesive body 3 and the adhesive surface 21, and adhere the protective surface 341 to the adhesive surface 21.

[0087] S2: Flatten the mold cup 1 and adhere the inner surface 12 to the cup adhesive surface 311.

[0088] S3: Remove the combination of the molded cup 1 and the adhesive body 3 from the adhesive surface 21, peel off the first release liner 34 from the skin contact surface 321, adjust the shape of the molded cup 1, and attach the skin contact surface 321 to the breast.

[0089] S4: After use of the adhesive bra with replaceable adhesive, remove mold cup 1 and remove adhesive 3 from mold cup 1.

[0090] The adhesive body 3 is mainly made of adhesive material, and the cup adhesive surface 311 of the adhesive body 3 is adhesive. The adhesive body 3 has a certain thickness because it needs to adhere to the skin of the breast. Also, to simplify the manufacturing process, the adhesive body 3 generally has a sheet-like structure, and the surface of the sheet-like structure is flat.

[0091] Furthermore, the protective surface 341 is not adhesive, and after the adhesive body 3 is attached to the positioning body 2, the protective surface 341 can be removed from the adhesive surface 21 by manual operation. The adhesive body 3 further has a skin-attachment surface 321 below the protective surface 341. Since the skin-attachment surface 321 is adhesive, after the protective surface 341 is peeled off, the skin-attachment surface 321 can be attached to the breast.

[0092] This application provides a method for using an adhesive bra with a replaceable adhesive body. Compared to existing technologies, before using the adhesive bra with a replaceable adhesive body, the protective surface 341 of the adhesive body 3 is attached to the adhesive surface 21, fixing and positioning the adhesive body 3, so that the cup adhesive surface 311 becomes flat and does not shift or wrinkle. Next, the inner surface 12 of the molded cup 1 can be quickly attached to the cup adhesive surface 311. This simplifies the adhesive operation, saves time during the adhesive operation, improves operational efficiency, ensures adhesiveness during use, and improves comfort performance. At the same time, the adhesive body 3 can be replaced by the user, making it environmentally friendly and beneficial to human health.

[0093] In some embodiments, before step S1 and / or after step S4, the method further includes: washing the mold cup 1 to keep it clean and ready for convenient reuse, and removing any residual colloid adhering to the inner surface 12.

[0094] If mold cup 1 is washed before step S1, the washed mold cup 1 must be dried before proceeding to step S1.

[0095] The foregoing describes only preferred embodiments of this application and is not intended to limit it. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the scope of protection of this application.
