Description

Replaceable adhesive surface chest patch and use method

[0001] This patent 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 06, 2024. The disclosure of the prior applications is incorporated by reference in its entirety. TECHNICAL FIELD

[0002] The present application belongs to the technical field of underwear, more specifically, relates to a replaceable adhesive surface chest patch and use method. BACKGROUND

[0003] The chest patch is a close-fitting product that is attached to the skin during use. The inner side of the chest patch has an adhesive layer. The adhesive layer is formed on the chest patch by hand brushing or hot melt transfer. During use, the adhesive layer is attached to the skin; when not in use, the adhesive layer is covered with a release paper layer. If the chest patch is not properly stored after use, such as if the release paper layer is not properly attached or the release paper layer is lost, the adhesive layer will stick to dust and other impurities, making it difficult to clean the adhesive layer and reducing its adhesion. In addition, the adhesive layer can breed bacteria when the chest patch is used repeatedly, which is not good for human health.

[0004] To solve the above problems, in the prior art, there are products in which the chest patch and the adhesive layer are in a separate structure, i.e., the chest patch and the adhesive layer are independent products. During use, the adhesive layer is first attached to the chest patch, and then the adhesive layer is attached to the skin as a combination. The inventors have found that because the chest patch is made of an elastic material and the adhesive layer is made of a gel material, both have a high degree of deformation, making it difficult for humans to attach the adhesive layer evenly to the chest patch during use. The adhesive layer will wrinkle and cannot be completely attached to the skin, resulting in poor adhesion and discomfort when attached to the skin, with poor comfort. TECHNICAL PROBLEM

[0051] In order to make the technical problems, technical solutions and beneficial effects of the present application more clear, the present application will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.

[0052] Please refer to Figs. 1 to 4, the chest patch with replaceable adhesive surface according to the present application will be described. The chest patch with replaceable adhesive surface comprises a mold cup 1, an adhesive body 3 and a positioning body 2. The mold cup 1 is made of elastic material; the mold cup 1 has an outer surface 11 and an inner surface 12 arranged oppositely; the adhesive body 3 has a cup surface 311 and a protective surface 341 arranged oppositely; the cup surface 311 is adhered to the inner surface 12; the positioning body 2 has an adhesive surface 21, and the positioning body 2 is used for limiting the shape of the mold cup 1 or the adhesive body 3.

[0053] Among them, the outer surface 11 can be adhered to the adhesive surface 21 to limit the shape of the mold cup 1, and the cup surface 311 is adhered to the inner surface 12; or the protective surface 341 can be adhered to the adhesive surface 21 to limit the shape of the adhesive body 3, and the inner surface 12 is adhered to the cup surface 311.

[0054] The mold cup 1 is generally in a circular sheet structure or a sheet structure similar to a circle. The mold cup 1 is convex in the middle part relative to the outer peripheral edge part after being made into a shape, and the mold cup 1 can be formed into a shape in which the outer finish 11 is curved and the inner lining 12 is flat when being shaped or designed.

[0055] When the mold cup 1 is used, since the mold cup 1 is made of an elastic material (such as solid silicone, liquid silicone or thermoplastic elastomer), the mold cup 1 has softness and deformation ability, and the mold cup 1 can be deformed so that the inner lining 12 is a concave curved surface to adapt to the structure of the human breast.

[0056] It should be noted that the mold cup 1 can be used independently, as shown in FIG. 1, or two mold cups 1 can be used in combination. If two mold cups 1 are used in combination, the two mold cups 1 are connected through the middle connecting piece 13, as shown in FIG. 4, and the middle connecting piece 13 is integrally formed with the two mold cups 1. Whether one mold cup 1 is used alone or two mold cups 1 are used in combination, each mold cup 1 is shaped by the positioning body 2, and each mold cup 1 is also attached to the skin by the adhesive body 3.

[0057] The adhesive body 3 is mainly made of a gel material, and the cup-attached surface 311 of the adhesive body 3 has adhesion. Since the adhesive body 3 needs to be attached to the skin of the breast, the adhesive body 3 has a certain thickness, and in order to simplify the manufacturing process, the adhesive body 3 is generally in a sheet structure, and the surface of the sheet structure is a flat surface. The adhesive body 3 and the mold cup 1 are in a split structure, that is, the adhesive body 3 and the mold cup 1 are independently manufactured and independently packaged. When not in use, the adhesive body 3 and the mold cup 1 are placed separately, and before use, the adhesive body 3 is attached to the inner lining 12.

[0058] Since the mold cup 1 itself has softness and deformation ability, and the adhesive body 3 also has deformation ability, if the adhesive body 3 is directly attached to the inner lining 12, on the one hand, the inner lining 12 is not easy to completely contact with the flat structure of the adhesive body 3, and there will be many small gaps between the two; on the other hand, the mold cup 1 itself is soft, and when attaching the adhesive body 3, even if the mold cup 1 is placed on a flat table, human will inevitably exert force on the mold cup 1, causing the mold cup 1 to deform and misalign, making it difficult for the adhesive body 3 to completely correspond to the mold cup 1, and the attachment operation takes a long time and is complex. The positioning body 2 is used to shape and position the mold cup 1 or the adhesive body 3 to avoid deformation of the mold cup 1 or the adhesive body 3.

[0059] Specifically, the adhesion operation can be performed by positioning one of the two, i.e., the mold cup 1 or the adhesive body 3. For example, first, the mold cup 1 is aligned with the adhesion surface 21, and the outer decorative surface 11 is attached to the adhesion surface 21. The mold cup 1 is fixed and positioned and cannot be moved, and the inner attached surface 12 can remain flat or slightly convex. Then, the adhesive body 3 with a flat structure is adhered to the inner attached surface 12. Since the mold cup 1 is made of an elastic material (such as solid silicone, liquid silicone, or thermoplastic elastomer), it has a certain elasticity, so it can ensure that the outer decorative surface 11 is completely attached to the adhesion surface 21.

[0060] Compared with the adhesion of the unshaped surface to the flat surface, the flat cup-attached surface 311 is adhered to the shaped inner attached surface 12, which can ensure that the cup-attached surface 311 is completely adhered to the inner attached surface 12, and there is no gap between the two, and the adhesive body 3 will not wrinkle. Moreover, the positioning body 2 positions the mold cup 1, and even if force is applied to the mold cup 1 during the adhesion operation, the positioning body 2 can limit the deformation of the mold cup 1, so that the adhesive body 3 is quickly attached to the inner attached surface 12, simplifying the adhesion operation, saving adhesion operation time, and improving operation efficiency.

[0061] For another example, first, the adhesive body 3 is aligned with the adhesion surface 21, and the protective surface 341 is adhered to the adhesion surface 21. The adhesive body 3 is fixed and positioned and cannot be moved. Since the adhesive body 3 has a sheet structure, it can ensure that the cup-attached surface 311 remains flat, and then the outer decorative surface 11 of the mold cup 1 is adhered to the cup-attached surface 311.

[0062] It should be noted that the protective surface 341 has no adhesion, and after the adhesive body 3 is adhered to the positioning body 2, the protective surface 341 can be separated from the adhesion surface 21 by artificial operation. The adhesive body 3 also has a skin-attached surface 321 inside the protective surface 341, and the skin-attached surface 321 has adhesion. After the protective surface 341 is torn off, the skin-attached surface 321 can be attached to the breast.

[0063] Since the shape of the mold cup 1 is slightly larger than the shape of the adhesive body 3, in order to further facilitate user operation and use, it is preferred that the mold cup 1 is first fixed to the positioning body 2, and then the adhesive body 3 is adhered to the inner attached surface 12.

[0064] It should be noted that the positioning body 2, the mold cup 1, and the adhesive body 3 are of a split structure, that is, the positioning body 2, the mold cup 1, and the adhesive body 3 are independently manufactured and packaged. When not in use, the positioning body 2, the mold cup 1, and the adhesive body 3 are placed independently, and when in use, the mold cup 1 or the adhesive body 3 is attached to the adhesion surface 21. In addition, the positioning body 2, the adhesive body 3, and the mold cup 1 are sold at the same time.

[0065] The positioning body 2 can be made of hard material and has certain hardness, so as to support the mold cup 1 or the adhesive body 3 during the bonding operation and avoid deformation of the mold cup 1 or the adhesive body 3. The positioning body 2 is coated with a thin adhesive layer to form a bonding surface 21. The adhesive layer has adhesion and hardness and cannot be deformed at will. The adhesive layer can bond the elastic mold cup 1 and the non-adhesive protective surface 341. Under the action of external force caused by human tearing, the adhesive layer can also separate from the elastic mold cup 1 and the protective surface 341.

[0066] The positioning body 2 can also be directly selected as a fixed adhesive body (such as double-sided adhesive tape with thickness) having a fixed shape. One side of the adhesive body has adhesion and is a bonding surface 21. The adhesive body can also be adhered to a flat table top or a flat platform to fix the mold cup 1 or the adhesive body 3 by means of adhesive. The fixed shape of the adhesive body cannot be deformed at will. The adhesive body can bond the elastic mold cup 1 and the non-adhesive protective surface 341. Under the action of external force caused by human tearing, the adhesive body can also separate from the elastic mold cup 1 and the protective surface 341.

[0067] Compared with the prior art, the positioning body 2 of the breast patch with replaceable adhesive surface provided in the application can fix and limit the mold cup 1 or the adhesive body 3. Before use, the outer decorative surface 11 of the mold cup 1 can be adhered to the bonding surface 21. The mold cup 1 is fixed and limited by the positioning body 2 and cannot be moved out of position. Therefore, the adhesive body 3 can be quickly and smoothly adhered to the inner adhesive surface 12 by human beings, so as to avoid wrinkles of the adhesive body 3. Alternatively, the protective surface 341 of the adhesive body 3 can be adhered to the bonding surface 21. The adhesive body 3 is fixed and limited by the positioning body 2 and cannot be moved out of position. Therefore, the mold cup 1 can be quickly and smoothly adhered to the cup surface 311 by human beings. During use, the combination of the mold cup 1 and the adhesive body 3 is removed from the bonding surface 21, and the adhesive body 3 is adhered to the breast. Since the adhesive body 3 has no wrinkles, the adhesive body 3 can be completely adhered to the breast, so as to ensure bonding viscosity and use comfort.

[0068] The mold cup 1 and the adhesive body 3 of the breast patch with replaceable adhesive surface provided in the embodiment can be repeatedly used for many times, are environmentally friendly and have low use cost. When not in use, the adhesive body 3, the mold cup 1 and the positioning body 2 are independently packaged, so as to not breed bacteria and be more beneficial to human health.

[0069] In some embodiments, the adhesive body 3 can have the structure shown in FIG. 5. As shown in FIG. 5, the adhesive body 3 includes an adhesive main body and a first release paper layer 34. One side of the adhesive main body is a cup surface 311, and the other side is a skin surface 321. One side of the first release paper layer 34 is adhered to the skin surface 321, and the other side is a protective surface 341.

[0070] The cup-adhering surface 311 and the skin-adhering surface 321 are both adhesive. The cup-adhering surface 311 is used to adhere to the inner-adhering surface 12, and the skin-adhering surface 321 is used to adhere to the breast. The first release paper layer 34 itself is not adhesive, but has a certain hardness to maintain a flat state. The first release paper layer 34 is covered on the skin-adhering surface 321 to protect the skin-adhering surface 321 and avoid the skin-adhering surface 321 from sticking impurities before adhering to the skin, which affects the adhesion and use comfort.

[0071] Before the adhesive body 3 is adhered, the first release paper layer 34 is adhered to the skin-adhering surface 321. The first release paper layer 34 itself has a certain hardness to maintain a flat state of the adhesive body 3 as a whole, thereby further ensuring that the adhesive body 3 is seamlessly adhered to the cup 1. After the combination of the adhesive body 3 and the cup 1 is removed from the positioning body 2, the first release paper layer 34 is torn off to expose the skin-adhering surface 321.

[0072] Since the adhesive body 3 and the cup 1 are independently manufactured and packaged, when not in use, the adhesive body 3 and the cup 1 are independently placed. In order to ensure the adhesion of the cup-adhering surface 311, a second release paper layer can be adhered to the cup-adhering surface 311.

[0073] In some embodiments, the above-mentioned adhesive body can adopt a structure as shown in FIG. 5. Referring to FIG. 5, the adhesive body includes a first adhesive layer 31, an intermediate elastic layer 33, and a second adhesive layer 32 which are sequentially adhered. An outer surface of the first adhesive layer 31 is a cup-adhering surface 311, and an outer surface of the second adhesive layer 32 is a skin-adhering surface 321.

[0074] The first adhesive layer 31 is used to adhere to the inner-adhering surface 12, and the second adhesive layer 32 is used to adhere to the skin. Preferably, the first adhesive layer 31 is a pressure-sensitive adhesive layer which has good adhesion and peeling strength, is suitable for adhering to the cup 1, and is not easy to fall off and displace after being adhered. The second adhesive layer 32 is a silicone gel layer which is made of silicone gel and has low peeling strength, so that it will not cause pain to the user when being torn off. A plurality of small holes can be provided on the silicone gel layer to improve the moisture permeability and air permeability, so that the adhesion is more comfortable.

[0075] The intermediate elastic layer 33 serves as a substrate for coating the first adhesive layer 31 and the second adhesive layer 32, so that the adhesive body 3 is more easily shaped. The intermediate elastic layer 33 also provides support for the first adhesive layer 31 and the second adhesive layer 32, so that the adhesive body 3 as a whole can be torn off from the cup 1, thereby ensuring that the cup 1 and the adhesive body 3 can be used again.

[0076] It should be noted that the intermediate elastic layer 33 needs to have waterproof and air permeable properties and should not cause any harm to the human skin.

[0077] Preferably, the intermediate elastic layer 33 is made of cloth or thin film material such as silicon rubber film or polyurethane film (PU film). The intermediate elastic layer 33 itself has elasticity, and the layered structure formed has contractility and extensibility, so that the entire adhesive body 3 has contractility and extensibility.

[0078] Specifically, before the adhesive body 3 is adhered to the cup 1, the adhesive body 3 is first flattened. Since the intermediate elastic layer 33 has extensibility, when the adhesive body 3 is manually flattened, the intermediate elastic layer 33 expands, causing the first adhesive layer 31 to also expand, so that the cup-facing surface 311 remains completely attached to the inner cup surface 12. After the adhesive body 3 is adhered, the combination of the cup 1 and the adhesive body 3 is removed from the adhesive surface 21, and the cup 1 is no longer limited in position and returns to the structure in the use state. At this time, the cup 1 also deforms the adhesive body 3. Since the intermediate elastic layer 33 has contractility and extensibility, after changing from a flat surface to a curved surface, the part coated with the first adhesive layer 31 can expand, and the part coated with the second adhesive layer 32 can contract, so that the first adhesive layer 31 expands and the second adhesive layer 32 contracts, causing the adhesive body 3 to adapt to the concave curved surface of the inner cup surface 12 in the use state, and the skin-facing surface 321 is wrinkle-free.

[0079] In some embodiments, after the cup-facing surface 311 is attached to the inner cup surface 12, the outer peripheral edge of the adhesive body 3 does not protrude beyond the outer peripheral edge of the cup 1.

[0080] In one embodiment, the outer peripheral edge of the adhesive body 3 coincides with the outer peripheral edge of the cup 1, so as to ensure that the back surface of the cup 1 can be completely attached to the breast, thereby ensuring the contact area between the cup 1 and the breast, so as to enhance the adhesion strength between the cup 1 and the breast; at the same time, the protection effect of the cup 1 on the breast is ensured, and the problem of exposure is avoided.

[0081] In another embodiment, the outer peripheral edge of the cup 1 protrudes beyond the outer peripheral edge of the adhesive body 3, that is, the adhesive body 3 does not completely cover the cup 1. In the above manner, while ensuring the positioning between the breast and the cup 1, the adhesion range between the cup 1 and the breast is reduced, the wearer's discomfort is avoided, and the wearing experience is optimized; in this case, as long as the size of the breast of the wearer corresponding to the cup 1 is suitable, the problem of exposure will not occur.

[0082] In some embodiments, the positioning body 2 can adopt the structure shown in FIGS. 1, 2 and 6. Referring to FIGS. 1, 2 and 6, the positioning body 2 is an attachment device having a volume cavity, the cavity structure of the volume cavity is adapted to the shape and thickness of the cup 1, and the cavity wall of the volume cavity is the adhesive surface 21.

[0083] The fitting device can be made of hard material and has certain hardness. The fitting device can be regarded as a flat panel, one side of the flat panel is provided with a downward recessed volume cavity, the volume cavity is used for shaping and limiting the mold cup 1 or the adhesive body 3, especially for shaping and limiting the mold cup 1. Since the cavity structure of the volume cavity is matched with the shape structure of the mold cup 1, after the mold cup 1 is placed in the volume cavity by human, the volume cavity limits the state of the mold cup 1, so that the inner lining surface 12 can be kept as a plane, thereby facilitating the adhesion of the adhesive body 3 with the flat structure and the inner lining surface 12.

[0084] Specifically, the mold cup 1 has a non-uniform thickness structure. Preferably, in order to adapt to the shape of the breast, the thickness of the mold cup 1 decreases from the center point to the outer peripheral edge, that is, the thickness of the center point of the mold cup 1 is the largest, and the thickness of the outer peripheral edge is the smallest.

[0085] The mold cup 1 is convex at the middle part relative to the outer peripheral edge part after being made and shaped, and the mold cup 1 can be shaped to have a curved outer surface 11 and a flat inner lining surface 12 during shaping or design, and the mold cup 1 is made of elastic material (such as solid silicone, liquid silicone or thermoplastic elastomer), so that the mold cup 1 itself has softness and deformation ability, and can be deformed during use, so that the inner lining surface 12 is concave curved, so as to adapt to the shape of the breast.

[0086] The design of the mold cup 1 as a non-uniform thickness structure can slow down the deformation of the outer surface 11, and since the cavity structure of the volume cavity is matched with the shape and thickness of the mold cup 1, the inner lining surface 12 can be flat after the mold cup 1 is limited in the volume cavity, and the outer surface 11 is still curved, as shown in FIG. 6, thereby facilitating the next step of adhesion of the adhesive body 3.

[0087] In addition, since the cavity structure of the volume cavity is matched with the shape and thickness of the mold cup 1, that is, the height of each point of the volume cavity is also not equal, the cavity wall of the volume cavity, that is, the adhesion surface 21 is an arc surface, and the adhesion surface 21 has more limiting directions relative to the flat structure, and can limit the mold cup 1 in multiple directions during adhesion of the adhesive body 3.

[0088] Since the positioning body 2 only has the volume cavity, the structure is simple, easy to manufacture, and low in manufacturing cost. Compared with the way of manually brushing glue or using hot melt forming adhesive body 3 on the mold cup 1, the replaceable adhesive surface breast patch provided in the embodiment can be used repeatedly, has lower use cost, and when not in use, the adhesive body 3 is independently packaged, does not breed bacteria, and is more beneficial to human health.

[0089] The volume cavity can define the adhesive body 3 in addition to defining the mold cup 1. Since the adhesive body 3 is a planar and equal-thickness structure, after the adhesive body 3 is bonded to the volume cavity, a curved and equal-thickness structure is formed, and the curved shape of the cup-adhering surface 311 is adapted to the curved shape of the bonding surface 21, that is, to the curved shape of the outer decorative surface 11, thereby facilitating bonding of the mold cup 1 to the adhesive body 3.

[0090] In another embodiment, the positioning body 2 is a fitting device without a volume cavity, and the fitting device is a planar plate. A glue layer is coated on the surface of the fitting device to form the bonding surface 21. The bonding surface 21 is flush with the outer surface of the fitting device, that is, the outer surface of the fitting device can form the bonding surface 21.

[0091] In some embodiments, the mold cup 1, the adhesive body 3, and the positioning body 2 can also adopt the structure shown in FIG. 3. Referring to FIG. 3, the mold cup 1 is provided with first air holes 14, and the adhesive body 3 is provided with second air holes 35. The bonding surface 21 is provided with positioning columns 211, which are inserted into the first air holes 14 and the second air holes 35 for limiting.

[0092] It should be noted that the mold cup 1 is provided with a plurality of first air holes 14, and the adhesive body 3 is provided with a plurality of second air holes 35. During the design and manufacture of the mold cup 1 and the adhesive body 3, the positions of the plurality of first air holes 14 correspond to the positions of the plurality of second air holes 35 one by one. The first air holes 14 and the second air holes 35 are both used for air permeability to ensure the air permeability of the breast patch.

[0093] Since the mold cup 1 and the adhesive body 3 are separately manufactured and independently packaged, in order to ensure that the plurality of first air holes 14 correspond to the plurality of second air holes 35 one by one after the mold cup 1 is bonded to the adhesive body 3, the positioning columns 211 are further provided on the bonding surface 21. When the outer decorative surface 11 of the mold cup 1 is adhered to the bonding surface 21, the first air holes 14 also pass through the positioning columns 211, and when the cup-adhering surface 311 of the adhesive body 3 is adhered to the inner-adhering surface 12, the second air holes 35 also pass through the positioning columns 211. Similarly, if the adhesive body 3 is adhered first, the second air holes 35 pass through the positioning columns 211, and then the first air holes 14 pass through the positioning columns 211. Through the positioning columns 211, the axial correspondence between the first air holes 14 and the second air holes 35 is ensured.

[0094] It should be noted that the number of the first air holes 14 is greater than the number of the positioning columns 211, and preferably, the number of the positioning columns 211 is three. Although only three first air holes 14 and three second air holes 35 are shown in FIG. 3, the number is not limited to three.

[0095] In some embodiments, the chest patch with replaceable adhesive surface can also adopt the structure shown in Figure 1. Referring to Figure 1, the chest patch with replaceable adhesive surface further comprises a pressure roller 4. After the cup surface 311 is adhered to the inner surface 12, the pressure roller 4 is used to roll the adhesive body 3; or after the inner surface 12 is adhered to the cup surface 311, the pressure roller 4 is used to roll the mold cup 1.

[0096] After the adhesive body 3 is manually adhered to the mold cup 1, the pressure roller 4 can be used to roll on the protective surface 341 or the outer surface 11 to squeeze out small bubbles between the adhesive body 3 and the mold cup 1, further improving the adhesion between the adhesive body 3 and the mold cup 1.

[0097] The pressure roller 4 can be packaged together with the positioning body 2 or separately packaged. The pressure roller 4 is sold together with the positioning body 2, the adhesive body 3 and the mold cup 1.

[0098] Based on the same inventive concept, the application also provides a method for using the chest patch with replaceable adhesive surface. The method comprises the following steps:

[0099] S1: aligning the mold cup 1 with the adhesive surface 21, and adhering the outer surface 11 to the adhesive surface 21;

[0100] S2: flattening the adhesive body 3, and adhering the cup surface 311 to the inner surface 12;

[0101] S3: taking the mold cup 1 with the adhesive body 3 from the adhesive surface 21, adjusting the shape of the mold cup 1, and adhering the adhesive body 3 to the breast;

[0102] S4: after use, taking off the mold cup 1, and tearing off the adhesive body 3 from the mold cup 1.

When not in use, the positioning body 2, the mold cup 1 and the adhesive body 3 are independently placed, and when in use, the mold cup 1 is adhered to the adhesive surface 21. In addition, the positioning body 2, the adhesive body 3 and the mold cup 1 are sold together. One mold cup 1 can be attached to multiple adhesive bodies 3, and when the viscosity of the adhesive body 3 decreases, a new adhesive body 3 can be replaced.

[0104] Since the mold cup 1 itself has softness and deformation ability, if the adhesive body 3 is directly adhered to the inner surface 12, on the one hand, the inner surface 12 is not easy to fully contact with the adhesive body 3 of planar structure, and there are many small gaps between them; on the other hand, the mold cup 1 itself is soft, and when adhering the adhesive body 3, force will be inevitably applied to the mold cup 1, causing the mold cup 1 to deform, so that the adhesive body 3 is difficult to fully correspond to the mold cup 1, the adhesion operation takes a long time, and the operation is complex. The positioning body 2 is used to shape and position the mold cup 1 to avoid deformation of the mold cup 1.

[0105] Specifically, in step S1, the mold cup 1 is aligned with the adhesive surface 21, and the outer decorative surface 11 is attached to the adhesive surface 21, and the inner adhesive surface 12 can be kept flat or slightly convex to the adhesive surface 21.

[0106] In step S2, the adhesive body 3 is attached to the shaped inner adhesive surface 12 relative to the unshaped surface being attached to the flat surface, which can ensure that the cup-attached surface 311 is completely attached to the inner adhesive surface 12 without any gap therebetween, and the adhesive body 3 will not wrinkle. Moreover, in step S2, even if force is applied to the mold cup 1, the positioning body 2 can limit the deformation of the mold cup 1, so that the adhesive body 3 is quickly attached to the inner adhesive surface 12.

[0107] In addition, in step S2, after the adhesive body 3 is manually attached to the inner adhesive surface 12, small bubbles between the adhesive body 3 and the mold cup 1 can be squeezed out by pressing the adhesive body 3 or using a pressure roller 4 to roll and squeeze the adhesive body 3.

[0108] The use method of the replaceable adhesive surface breast patch provided by the present application, compared with the prior art, first attaches the outer decorative surface 11 of the mold cup 1 to the adhesive surface 21 before use, the mold cup 1 is shaped and limited, the inner adhesive surface 12 can be kept flat or slightly convex to the adhesive surface 21, then the cup-attached surface 311 of the adhesive body 3 can be quickly attached to the inner adhesive surface 12, which simplifies the attachment operation, saves the attachment operation time, improves the operation efficiency, avoids the wrinkle of the adhesive body 3, ensures the use viscosity, improves the comfort performance, and the user can replace the adhesive body 3, which is environmentally friendly and beneficial to human health.

[0109] It should be noted that the positioning body 2 only has the adhesive surface 21, which has a simple structure, is easy to manufacture, and has low manufacturing cost. Compared with the way of manually brushing glue or using hot melt forming adhesive body 3 on the mold cup 1, the use method of the replaceable adhesive surface breast patch provided by the present embodiment can repeatedly use the mold cup 1 and the adhesive body 3, which has lower use cost, and when not in use, the adhesive body 3 is independently packaged, which will not breed bacteria and is more beneficial to human health.

[0110] In some embodiments, the adhesive body 3 includes a glue body and a first release paper layer 34. One side of the glue body is the cup-attached surface 311, and the other side is the skin-attached surface 321; one side of the first release paper layer 34 is attached to the skin-attached surface 321, and the other side is the protective surface 341. The first release paper layer 34 has a flat structure.

[0111] Specifically, step S3 includes: taking the mold cup 1 with the adhesive body 3 attached thereon from the adhesive surface 21, tearing the first release paper layer 34 from the skin-attached surface 321, adjusting the shape of the mold cup 1, and attaching the skin-attached surface 321 to the breast.

[0112] The first release paper layer 34 has a hardness and can maintain a flat state. Before step S1, the first release paper layer 34 is attached to the skin-facing surface 321, and the hardness of the first release paper layer 34 can make the adhesive body 3 maintain a flat state as a whole, and the adhesive body 3 can be further attached to the mold cup 1 without gaps on the adhesive surface 21 in step S2. After the adhesive body 3 is attached, the first release paper layer 34 is torn off.

[0113] In some embodiments, before step S1 and / or after step S4, the mold cup 1 is cleaned to keep the mold cup 1 clean, facilitate reuse, and remove residual adhesive on the inner adhesive surface 12.

[0114] If the mold cup 1 is cleaned before step S1, the mold cup 1 needs to be dried before step S1 continues.

[0115] Based on the same inventive concept, the embodiment also provides another use method of the replaceable adhesive surface breast patch. The adhesive body 3 includes an adhesive main body and a first release paper layer 34. One side of the adhesive main body is the cup-facing surface 311, and the other side is the skin-facing surface 321. One side of the first release paper layer 34 is attached to the skin-facing surface 321, and the other side is the protective surface 341.

[0116] The use method includes the following steps:

[0117] S1: align the adhesive body 3 with the adhesive surface 21, and attach the protective surface 341 to the adhesive surface 21;

[0118] S2: flatten the mold cup 1, and attach the inner adhesive surface 12 to the cup-facing surface 311;

[0120] S4: after use, remove the mold cup 1, and tear the adhesive body 3 from the mold cup 1.

[0121] The adhesive body 3 is mainly made of adhesive material, and the cup-facing surface 311 of the adhesive body 3 has adhesion. Since the adhesive body 3 needs to be attached to the skin of the breast, the adhesive body 3 has a certain thickness, and in order to simplify the manufacturing process, the adhesive body 3 is generally in a sheet structure, and the surface of the sheet structure is a plane.

[0122] It should be noted that the protective surface 341 has no adhesion, and after the adhesive body 3 is attached to the positioning body 2, the protective surface 341 can be separated from the adhesive surface 21 through manual operation. The adhesive body 3 has the skin-facing surface 321 inside the protective surface 341, the skin-facing surface 321 has adhesion, and after the protective surface 341 is torn off, the skin-facing surface 321 can be attached to the breast.
