Description

Technical Field

[0001] The utility model belongs to the field of underwear, and in particular relates to a breast patch, in particular to a breast patch with N adhesive layers. Background Art

[0002] A breast patch, also called a nipple patch, generally comprises a cup body and an adhesive layer pasted on the inner surface of the cup body. The adhesive layer has a certain degree of stickiness. In order to prevent the adhesive layer from being contaminated by dust and other impurities, the breast patch is usually also provided with a protective layer covering and pasted on the adhesive layer. In the prior art, the adhesive layer is generally directly formed by hand-brushing glue or hot-melt method and pasted and covered on the inner surface of the cup body with a whole piece of structure. The shape and outer contour size of the whole piece of adhesive layer are the same or substantially the same as those of the inner surface of the cup body, and the whole inner surface of the cup body is completely or substantially covered. When in use, the protective layer must be torn off first, and the stickiness of the adhesive layer is used to stick the breast patch to the user's chest. The adhesive layer covers the chest and completely or substantially encloses the covered area of the chest. In addition, because the whole piece of adhesive layer in the prior art is a whole, the stickiness of the whole piece of adhesive layer is the same. Since the stickiness of the whole piece of adhesive layer is the same, the adhesive force it provides to the chest is also the same. Therefore, breast patches with this structure in the prior art generally have these problems:

[0003] Since the conventional breast patch has only one adhesive layer, and the adhesive layer can be used a limited number of times, when the adhesive layer reaches the upper limit or loses its stickiness, the entire breast patch cannot be used. However, the cup body of the breast patch can continue to be used multiple times, and the service life of the cup body is much longer than that of the adhesive layer. If the entire breast patch cannot be used any more, it will cause a waste of resources, and purchasing a new breast patch will result in a high cost for the user.

[0004] Since the adhesive layer is sticky and soft, even if the breast patch is equipped with multiple manually-adhesive adhesive layers as accessories for users to apply and replace by themselves, most users do not know how to apply the adhesive layer by themselves. Even if they know how to apply it by themselves, it is difficult to apply the entire adhesive layer straight and flat, and wrinkles are easily generated if it is not applied flat. Therefore, applying and replacing the adhesive layer by oneself is troublesome, inconvenient, time-consuming and labor-intensive.

[0005] Since the adhesive layer is a whole piece of structure and is pasted on the inner surface of the cup body as a whole, and since the cup body itself has an uneven structure with convex outside and concave inside in order to fit the breast, when the adhesive layer is pasted on the inner surface of the concave cup body as a whole piece, wrinkles often appear on the adhesive layer itself. The adhesive layer itself is sticky, and the surfaces of the adhesive layer at the wrinkles stick together and are not easy to separate. If you try to smooth out the wrinkles or forcibly separate them, the adhesive layer may be torn, holes may appear, or it may be partially damaged, thus affecting the service life of the adhesive layer and the breast patch.

[0006] Because the wrinkles cause the adhesive layer to have bulges, tears or partial damage on its surface, the user may feel a foreign object pressing against the corresponding part of the chest or other discomfort when using the chest patch.

[0007] Since the adhesive layer is a whole piece attached to the cup body, the adhesive layer may sometimes stick to the female nipple and the surrounding sensitive parts. The skin of the nipple and the surrounding sensitive parts is more easily injured when torn. If torn vigorously, it may even damage the skin of the nipple and the surrounding sensitive parts.

[0008] After the user sweats, the sweat will be trapped in the cup body defined by the entire adhesive layer and will not be easily discharged. Even if the adhesive layer is provided with ventilation holes, since the ventilation holes are generally small, wrinkles on the entire adhesive layer will squeeze or even flatten the ventilation holes, making it easy for the ventilation holes and the adhesive around them to stick together or block the ventilation holes, making it difficult for the sweat to be discharged. In addition to irritating the skin and causing discomfort to the user, the sweat that is difficult to discharge will also damage the adhesive of the adhesive layer and accelerate the wear of the adhesive layer.

[0009] When used, the adhesive layer of the breast patch is bonded to the user's chest, so that the user's chest is enclosed in the cup body wrapped by the adhesive layer and is almost airtight to the outside world. The airtightness can easily lead to chest sweating.

[0010] 8. Since the adhesive layer has the same viscosity, it cannot adapt to and match the different needs of different users. For example, some users need the bra patch to provide different and appropriate lifting force or adhesive force on the chest, some need the bra patch to have a better breast gathering effect after wearing, and some need the bra patch to have a good breast lifting or breast sagging prevention effect.

[0026] Furthermore, the chest patch also includes an Nth protective layer, and the Nth protective layer is detachably adhered to the Nth adhesive layer.

[0027] The chest patch of the present invention has the following advantages or beneficial effects:

[0028] 1. Since N layers of adhesive layers are provided on the inner surface of the cup body, when the first adhesive layer is used a certain number of times or loses its stickiness, the user can tear off this layer and continue to use the next adhesive layer, thereby continuing to use the breast patch until the last adhesive layer is used a certain number of times. This can save a lot of resources and has a low cost for users.

[0029] 2. Users do not need to replace the adhesive layer by themselves. Users only need to tear off the adhesive layer that has reached the upper limit of use to expose the next adhesive layer, and then they can continue to use the chest patch. It has a long service life, is easy to use, and saves time and effort.

[0030] 3. The bra patch of the present invention has an adhesive layer that is split into a non-integrated structure comprising at least two adhesive sheets, thereby avoiding or reducing the phenomenon that the adhesive layer of an integral structure is prone to wrinkling during use, thereby avoiding or reducing the phenomenon that the adhesive layer is torn or partially damaged due to wrinkles, thereby extending the service life of the adhesive layer and further extending the service life of the cup.

[0031] 4. Because wrinkles on the adhesive layer are avoided or reduced, the adhesive on the surface of the adhesive layer can remain relatively flat and smooth during use, and the user will not feel any foreign objects pressing against the surface or other discomfort caused by the bulges at the wrinkles when using it.

[0032] 5. Since the adhesive layer is split into a non-integrated structure including at least two adhesive sheets and pasted on the cup body, and the two adjacent adhesive sheets are spaced at an appropriate distance and a nipple accommodating area is reserved for accommodating the nipple, the adhesive layer is prevented from sticking to the skin of the female nipple and the surrounding sensitive parts, that is, the chance of the adhesive layer damaging the nipple and the surrounding sensitive parts of the skin is avoided or reduced, making it safer to use.

[0033] 6. The adhesive layer is split into at least two adhesive sheets that are attached to the cup body, with adjacent sheets spaced appropriately apart to form a nipple-receiving area for accommodating the nipple and several perspiration-wicking vents for perspiration. The perspiration-wicking vents extend from the nipple-receiving area to the edge of the cup body, connecting the interior of the cup body with the exterior. After perspiration, sweat is discharged through the perspiration-wicking vents. The perspiration-wicking vents prevent or minimize skin irritation and discomfort caused by sweat. The perspiration-wicking vents and nipple-receiving area also facilitate rapid drying of the cup body after cleaning.

[0034] 7. Because the protective layer is compatible with the adhesive layer, it is also split into at least two protective sheets affixed to the adhesive layer. The protective layer's non-monolithic structure also ensures that when it covers the adhesive layer, the perspiration ventilation channel and nipple receiving area are not covered, which facilitates ventilation inside and outside the cup body and facilitates rapid drying of the cup body after cleaning. At the same time, the outer edge of the adhesive layer is appropriately distanced from the outer edge of the cup body, and the protective layer completely covers the adhesive layer. The protective layer protects the adhesive layer from staining or damage, and the use of this protective layer also ensures that the adhesive surface is more durable, allowing for more uses and a longer lifespan.

[0035] 8. Since the adhesive layer is split into at least two adhesive sheets and the adjacent adhesive sheets are spaced at an appropriate distance to form a perspiration and ventilation channel, the inside of the chest patch is connected with the outside of the chest patch for ventilation, and the chest patch has good breathability.

[0036] 9. The width of the channel openings at both ends of the perspiration and ventilation channel is larger than the width of the channel body, which is convenient for ventilation between the inside and outside of the chest patch and also for the discharge of sweat.

[0037] 10. When in use, the perspiration and ventilation channel has one end opening facing upwards and the other end opening facing downwards, so that the sweat discharged by the user naturally flows downwards to facilitate perspiration.

[0038] 11. Since the adhesive layer can also be arranged on the edge of the inner surface of the cup body and the adhesive layer is in the shape of a long strip and extends along the edge of the inner surface of the cup body to form a nipple accommodating area and a perspiration and ventilation channel, this adhesive layer is not a whole piece structure, and the breast patch using this adhesive layer also has good breathability.

[0039] 12. Since N layers of adhesive layers are provided on the inner surface of the cup body, the thickness of the N layers of adhesive layers is N times thicker than that of a single layer of adhesive layer. The overall thickness of the nipple accommodating area and the perspiration and ventilation channel formed by the N layers of adhesive layers is thicker than that of the nipple accommodating area and the perspiration and ventilation channel formed by a single layer of adhesive layer, which makes the bra patch more breathable.

[0040] 13. Since there are at least two adhesive areas within the cup body and the adhesiveness of at least two of the adhesive areas is different, it can adapt to and match the different adhesive force requirements of different users. The breast patch can provide the user with appropriate lifting force or adhesive force based on the local differences in the chest. After wearing, the breast patch has a good effect of gathering the breasts, and it also has a good effect of lifting the breasts or preventing the breasts from sagging.

[0080] In view of the above technical problems existing in the prior art, the present invention provides a chest patch to solve the above technical problems. The technical solution of the chest patch is described in detail below in conjunction with specific implementation methods.

[0081] 1. First embodiment of the present utility model

[0082] A chest patch of the first embodiment of the utility model is as follows, see the attached drawings for details. Figures 1 to 12 :

[0083] The bra adhesive of the first embodiment comprises a pair of symmetrically arranged cups and a connecting device 7 located between the pair of cups for connecting the cups. Each cup comprises a cup body 1, N adhesive layers 2 and N protective layers 3, where N is an integer greater than or equal to 2. Figure 2 For reference, the left side of the cup is used for illustration. The cup body 1 includes an outwardly protruding cup body surface 11 and an inwardly recessed cup body surface 12. The cup body surface 12 itself is not sticky and is made of existing soft, skin-friendly materials, such as cloth, silicone rubber, etc.

[0084] The N layers of adhesive layer 2 include a first adhesive layer 2, a second adhesive layer 2, ..., an N-1th adhesive layer 2, and an N-layer adhesive layer 2. The N layers of protective layer 3 include a first protective layer 3, a second protective layer 3, ..., an N-2th protective layer 3, an N-1th protective layer 3, and an N-layer protective layer 3. The first layer of adhesive layer 2 is pasted on the inner surface 12 of the cup body, and the first layer of protective layer 3 is detachably pasted on the first layer of adhesive layer 2; the second layer of adhesive layer 2 is pasted on the first layer of protective layer 3, and the second layer of protective layer 3 is detachably pasted on the second layer of adhesive layer 2; and so on, until the N-1th protective layer 3 is detachably pasted on the N-1th adhesive layer 2, and the N-1th adhesive layer 2 is pasted on the N-1th protective layer 3. The N layers of adhesive layer 2 and the N-1th protective layer 3 are formed into a whole and pre-pasted on the inner surface 12 of the cup body. All N layers of adhesive layers 2 do not need to be pasted on the inner surface 12 of the cup body by the user. In order to protect the Nth adhesive layer 2 , an Nth protective layer 3 is further provided. The Nth protective layer 3 can also be detachably adhered to the Nth adhesive layer 2 .

[0085] Each of the N adhesive layers 2 is identical, and each adhesive layer 2 is split into at least two adhesive sheets, and is composed of at least two separate adhesive sheets. The adhesive layer 2 adopts a non-integrated structure to distinguish it from an integral structure. The adhesive layer 2 of this embodiment includes two adhesive sheets. Figure 4In the direction shown, it includes a first adhesive sheet 21 and a second adhesive sheet 22. The first adhesive sheet 21 and the second adhesive sheet 22 are respectively located on the left and right sides of the inner surface 12 of the cup body, and are spaced apart appropriately to form a perspiration and ventilation channel 4 for perspiration and ventilation. The first adhesive sheet 21 and the second adhesive sheet 22 form an enclosed state in the middle of the inner surface 12 of the cup body, and the center of the enclosed area is hollowed out to form a nipple receiving area 5 for accommodating the user's nipple and surrounding sensitive parts. The nipple receiving area 5 is interconnected with the perspiration and ventilation channel 4. Because each adhesive sheet is adhered to the inner surface 12 of the cup body, the perspiration and ventilation channel 4 is formed between adjacent adhesive sheets to ensure an appropriate distance between them, and the nipple receiving area 5 is also provided in the middle of the inner surface 12 of the cup body to ensure an appropriate distance between them. This non-integral adhesive layer is less likely to wrinkle during use than a single-piece adhesive layer. Since the inner surface 12 of the cup is not sticky, when the breast patch is attached to the wearer's chest, the inner surface 12 of the cup will not stick to the wearer's nipple and the surrounding sensitive parts. At the same time, since the nipple accommodating area 5 does not have an adhesive layer 2, the adhesive layer 2 can be prevented from sticking to the wearer's nipple and the surrounding sensitive parts, that is, damage to the nipple and the surrounding sensitive parts when tearing off the adhesive layer 2 can be avoided or reduced, making it more comfortable and safe to use.

[0086] In this embodiment, Figure 2 In the direction shown, the perspiration ventilation channel 4 includes a channel opening 401 and a channel body 402. When in use, preferably, the channel opening 401 at one end of the perspiration ventilation channel 4 faces upward, and the channel opening 401 at the other end faces downward, so that the sweat discharged by the user flows naturally downward to facilitate perspiration, and the width of the channel openings 401 at both ends of the perspiration ventilation channel 4 is greater than the width d of the channel body 402 (as shown in FIG. Figure 8 The nipple receiving area 5 is generally circular or oval, and it is understandable that the shape of the nipple receiving area 5 is not limited thereto and can be set to other different shapes as needed.

[0087] like Figure 9As shown, the adhesive layer 2 can be constructed using a flexible double-sided adhesive tape structure, comprising an intermediate layer 203, a cup body adhesive layer 201 adhered to one side of the intermediate layer 203, and a skin-contacting adhesive layer 202 adhered to the other side of the intermediate layer 203. The intermediate layer 203 serves as a base material, exhibiting a certain degree of softness, water resistance, and breathability. It is integrally formed with the cup body adhesive layer 201 and the skin-contacting adhesive layer 202 adhered to its two sides and has an appropriate thickness. The intermediate layer 203 is an elastic film layer, which can be made of a TPU layer, a TPR layer (TPR adhesive), a PTE layer (PTE adhesive), or a silicone rubber film. Preferably, the elastic film layer is a TPU layer, as TPU adhesives can adhere to a variety of materials. The cup body adhesive layer 201 is used to adhere to the cup body 1. Specifically, the cup body adhesive layer 201 adheres to the inner surface 12 of the cup body and is not easily removed. The cup body adhesive layer 201 can be made of a pressure-sensitive adhesive layer, and the pressure-sensitive adhesive layer can be made of materials such as silicone pressure-sensitive adhesive, acrylic pressure-sensitive adhesive, hot-melt pressure-sensitive adhesive, and acrylic adhesive. The cup body adhesive layer 201 has good adhesion and peeling strength, so that it is not easy to fall off or shift when it is attached to the inner surface 12 of the cup body. The skin-contacting adhesive layer 202 is attached to the other side of the intermediate layer 203. The skin-contacting adhesive layer 202 is made of environmentally friendly adhesive material and has a skin-friendly effect. It is used to make the chest patch adhere to the user's skin. Preferably, the skin-contacting adhesive layer 202 can be made of silicone gel material, such as platinum addition silicone gel or condensation-curing silicone gel. The viscosity of the cup body adhesive layer 201 is greater than that of the skin-contacting adhesive layer 202, so that the adhesion between the cup body adhesive layer 201 and the inner surface 12 of the cup body is greater than the adhesion between the skin-contacting adhesive layer 202 and the user's skin.

[0088] Understandable, such as Figure 10 As shown, the adhesive layer 2 adopts another double-sided tape structure, which has only one cup body adhesive layer 201 and one skin-contacting adhesive layer 202 adhered to each other, that is, this structure is a double-sided tape structure with the middle layer 203 removed, and the cup body adhesive layer 201 is directly adhered to the skin-contacting adhesive layer 202 to form a whole and has an appropriate thickness. It is adhered to the cup body 1 by using the cup body adhesive layer 201, and is detachably adhered to the protective layer 3 by using the skin-contacting adhesive layer 202.

[0089] The outer edge of the adhesive layer 2 is at an appropriate distance d1 from the outer edge of the cup body 1. The size of the adhesive layer 2 is slightly smaller than that of the cup body 1 to prevent the outer edge of the adhesive layer 2 from extending out of the outer edge of the cup body 1. The purpose is to prevent the outer edge of the adhesive layer 2 from sticking to dust and impurities, which will affect its service life. Dust and impurities will also dirty the adhesive layer, which is not beautiful.

[0090] Each of the N protective layers 3 is identical, and each protective layer 3 can be detachably attached to a corresponding adhesive layer 2 to protect each adhesive layer 2 . The Nth protective layer 3 is pasted on the Nth adhesive layer 2 to protect the Nth adhesive layer 2. Each of the other N-1 protective layers 3 is not only used to protect its corresponding adhesive layer 2, but also used to carry the next adhesive layer 2. For example, the first protective layer 3 is not only used to protect the first adhesive layer 2, but also used to carry the second adhesive layer 2. At this time, one side of the first protective layer 3 is detachably pasted on the skin-contacting adhesive layer 202 of the first adhesive layer 2 to protect the first adhesive layer 2; and the other side of the first protective layer 3 is pasted on the skin-contacting adhesive layer 202 of the second adhesive layer 2 to carry the second adhesive layer 2. Since the viscosity of the cup body adhesive layer 201 is greater than the viscosity of the skin-contacting adhesive layer 202, the adhesion force between the second protective layer 3 and the second adhesive layer 2 is greater than the adhesion force between the second protective layer 2 and the first adhesive layer 2, and the adhesion between the second protective layer 3 and the second adhesive layer 2 is tighter and not easy to tear off. It should be noted that the adhesive force between the first adhesive layer 2 and the second protective layer 3 is greater than the adhesive force between the second adhesive layer 2 and the user's chest skin. This is so that when the second adhesive layer 2 is used, when the user removes the chest patch with the second adhesive layer 2, the second adhesive layer 2 and the first protective layer 3 remain adhered to the first adhesive layer 2 as a whole. That is, the second adhesive layer 2 is also indirectly adhered to the cup inner surface 12 through the first adhesive layer 2 and will not easily fall off the cup inner surface 12. By analogy, it can be seen that the adhesive force between the N-1th adhesive layer 2 and the N-1th protective layer 3 is greater than the adhesive force between the N-1th adhesive layer 2 and the user's chest skin. This ensures that when the user removes the chest patch with the N-1th adhesive layer 2, the N-1th adhesive layer 2 and the N-1th protective layer 3 remain adhered to the N-1th adhesive layer 2 as a whole. That is, the N-1th adhesive layer 2 is also indirectly adhered to the cup inner surface 12 through the N-1th adhesive layer 2 and will not easily fall off the cup inner surface 12.

[0091] When using the chest patch for the first time, the Nth protective layer 3 is removed from the Nth adhesive layer 2. The chest patch can then be attached to the user's chest using the adhesive properties of the Nth adhesive layer 2. When the chest patch is not in use, the Nth protective layer 3 is applied to the Nth adhesive layer 2. This protects the adhesive on the surface of the Nth adhesive layer 2 from soiling or damage. The use of the protective layer 3 also ensures that the adhesive properties of the adhesive layer 2 remain longer, allowing for more frequent uses and a longer lifespan. After use, the adhesive layer 2 can be cleaned before the protective layer 3 is applied to protect it. When the adhesive layer 2 (Nth) reaches its maximum usage limit or loses its adhesiveness, the user can remove the Nth adhesive layer 2 and continue using the adjacent adhesive layer 2 (N-1th adhesive layer) until the first adhesive layer 2 reaches its maximum usage limit. Since the N-1th protective layer 3 carries the Nth adhesive layer 2 and is firmly adhered to the Nth adhesive layer 2 and is not easy to tear off, if you want to tear off the Nth adhesive layer 2, you can directly tear off the N-1th protective layer 3 and then tear off the Nth adhesive layer 2.

[0092] Because the breast patch of this embodiment has N adhesive layers 2 on the inner surface 12 of the cup body, its theoretical use frequency is N times that of a breast patch with only one adhesive layer 2. This saves a significant amount of resources and reduces user costs. Furthermore, compared to conventional breast patches with only one adhesive layer that can be self-applied and replaced, the user of this embodiment does not need to apply or replace the adhesive layer themselves. The user simply tears off the adhesive layer that has reached its maximum number of uses, revealing the next adhesive layer. The user can then continue using the breast patch by leveraging the adhesive properties of the next adhesive layer. This eliminates the difficulty of aligning the adhesive layer on the inner surface of the cup body when applying or replacing it, and eliminates the problem of wrinkles in the adhesive layer caused by misalignment. This embodiment eliminates the need for the user to apply or replace the adhesive layer themselves, making it convenient to use and saving time and effort.

[0093] The protective layer 3 of this embodiment is adapted to the shape and size of the adhesive layer 2 and is a thin sheet structure with appropriate thickness and flexibility. The protective layer 3 can be made of a release film. The outer edge of the protective layer 3 is an appropriate distance d2 from the outer edge of the cup body 1. The size of the protective layer 3 is the same as or slightly smaller than the size of the cup body 1. The size of the protective layer 3 is greater than or equal to the size of the adhesive layer 2 so that the protective layer 3 can completely cover the adhesive layer 2 to protect the adhesive layer 2. The protective layer 3 includes two protective sheets, including a first protective sheet 31 and a second protective sheet 32. The shape and size of the first protective sheet 31 are adapted to the shape and size of the first adhesive sheet 21 and are adhered to the first adhesive sheet 21; the shape and size of the second protective sheet 32 are adapted to the shape and size of the second adhesive sheet 22 and are adhered to the second adhesive sheet 22.

[0094] like Figure 12 As shown, since the first adhesive sheet 21 or the second adhesive sheet 22 of the adhesive layer 2 has been split into two pieces compared to the single piece adhesive sheet of the prior art, and is also provided with a perspiration ventilation channel and a nipple receiving area, the probability of wrinkling during use has been greatly reduced. However, considering that the first adhesive sheet 21 or the second adhesive sheet 22 itself has a curved portion, a longer portion, or a wider portion, and the inner surface 12 of the cup body is a concave surface, to further prevent or reduce wrinkling in the curved portion or wider portion of the first adhesive sheet 21 or the second adhesive sheet 22 during use, a plurality of anti-wrinkle notches 29 are provided in the curved portion or wider portion of the first adhesive sheet 21 or the second adhesive sheet 22. In this way, the probability of wrinkling in the adhesive layer 2, especially in the curved portion or wider portion, during use is further reduced. Preferably, the anti-wrinkle notches 29 are V-shaped, U-shaped, or arc-shaped. As can be understood, since each protective layer 3 is adapted to the shape and size of each adhesive layer 2, specifically, the first protective sheet 31 and the second protective sheet 32 are adapted to the shape and size of the first adhesive sheet 21 and the second adhesive sheet 22, respectively, a plurality of anti-wrinkle notches 39 are correspondingly formed at the curved or wider portions of the first protective sheet 31 and the second protective sheet 32, corresponding to the positions of the first adhesive sheet 21 and the second adhesive sheet 22. Preferably, the anti-wrinkle notches 39 are similar to the anti-wrinkle notches, and are also V-shaped, U-shaped, or arc-shaped.

[0095] like Figure 12 As shown, since each adhesive layer 2 itself is sticky, in order to facilitate the user to tear off the adhesive layer 2 smoothly after the adhesive layer 2 has been used for a maximum number of times or has lost its stickiness, a tearing auxiliary portion 9 can be pre-fixed at the upper edge of each adhesive layer and / or each protective layer. When in use, the user can easily tear off the adhesive layer 2 and / or protective layer 3 to be torn off by using the tearing auxiliary portion 9.

[0096] Because the adhesive layer in the prior art is generally a whole piece with the same viscosity, the adhesive layer 2 of this embodiment includes two adhesive sheets, and the viscosity of these two adhesive sheets can of course be the same. Considering the differences in breast size and shape of different users, in order to adapt to and match the different adhesive force requirements of different users, some users hope that the breast patch will have a better breast gathering effect after wearing it, some need the breast patch to give a suitable lifting force or adhesive force to the local breast, and some need the breast patch to have a good effect of lifting the breast or preventing the breast from sagging. For this reason, Figure 11As shown, the cup body 1 of the present invention is further provided with a non-sticky area, a first sticky area and a second sticky area. The stickiness of the first sticky area and the second sticky area is different in strength. For example, if the stickiness of the first sticky area is stronger, the stickiness of the second sticky area is weaker. In this case, the stickiness of the first sticky area is stronger than that of the second sticky area. Vice versa, if the stickiness of the first sticky area is weaker, the stickiness of the second sticky area is stronger. In this case, the stickiness of the first sticky area is weaker than that of the second sticky area. The setting of different stickiness strengths of the first sticky area and the second sticky area provides users with at least two choices of stickiness or two types of adhesive strength. Figure 17 As shown, the first and second adhesive areas are located on the adhesive sheet of the adhesive layer 2, specifically corresponding areas on the skin-contacting adhesive layer 202 of the adhesive sheet. The adhesive strength of the corresponding areas of the skin-contacting adhesive layer 202 is pre-adjusted and adjusted as needed during the production of the breast patch. Although one of the first and second adhesive areas is a less adhesive area, the less adhesive area still has sufficient adhesion to allow for multiple breast applications. The areas within the nipple receiving area 5 and the areas within the perspiration-wicking and ventilation channels 4 are non-adhesive, as the inner surface 12 of the cup body itself is non-adhesive. In this embodiment, because each adhesive layer 2 includes a first adhesive sheet 21 and a second adhesive sheet 22, when the first adhesive sheet 21 is configured as the first adhesive area, the second adhesive sheet 22 is configured as the second adhesive area; alternatively, when the first adhesive sheet 21 is configured as the second adhesive area, the second adhesive sheet 22 is configured as the first adhesive area. By setting the first adhesive area and the second adhesive area with different adhesive strengths in different areas within the range of the cup body 1 as needed, since the adhesive force exerted on the chest by the adhesive area with stronger adhesiveness is different from the adhesive force exerted on the chest by the adhesive area with weaker adhesiveness, differentiated and different adhesive forces can be provided for different areas of the user's chest, so that the chest is under the action of different adhesive forces, so that the chest patch of this embodiment can give the user's chest a suitable lifting force or adhesive force that is locally different when used. After wearing, the chest patch has a good effect of gathering the chest, and the chest patch also has a good effect of lifting the chest or preventing the chest from sagging.

[0097] In this embodiment, it is more preferred that Figure 8As shown, the length H of the cup body 1 is 14.5 cm, the width W of the cup body 1 is 11 cm, the distance d1 between the outer edge of the adhesive layer 2 and the outer edge of the cup body 1 is 0.25 cm, and correspondingly, the distance d2 between the outer edge of the protective layer 3 and the outer edge of the cup body 1 is greater than or equal to 0 and less than or equal to 0.25 cm, and the width d of the channel body of the perspiration and ventilation channel 4 is 1 cm. Preferably, the shape of the nipple accommodating area 5 is elliptical, and the major axis a of the elliptical nipple accommodating area 5 is 7 cm and the minor axis b is 4 cm. Of course, the size of the breast patch and its various components and functional areas can be adjusted and adapted as needed, and are not limited to this. For ease of explanation, N in this embodiment is 2, and two layers of adhesive layers 2 and two layers of protective layers 3 are provided on the cup body 1. Preferably, N can be an integer between 3 and 10.

[0098] 2. Second embodiment of the present utility model

[0099] The second embodiment of the utility model, see Figures 13 to 15 The second embodiment is substantially the same as the first embodiment, and also includes a cup body 1, N adhesive layers 2', and N protective layers 3'. The main difference is that each adhesive layer 2' includes three adhesive sheets, including a first adhesive sheet 21', a second adhesive sheet 22', and a third adhesive sheet 23'. A perspiration-permeable channel 4' for perspiration and ventilation is formed between the first adhesive sheet 21' and the second adhesive sheet 22' at an appropriate distance. A perspiration-permeable channel 4' for perspiration and ventilation is also formed between the second adhesive sheet 22' and the third adhesive sheet 23' at an appropriate distance. A perspiration-permeable channel 4' for perspiration and ventilation is also formed between the third adhesive sheet 23' and the third adhesive sheet 21' at an appropriate distance. In this embodiment, the first adhesive sheet 21' is adhered to the left side of the cup body inner surface 12, the second adhesive sheet 22' is adhered to the upper right side of the cup body inner surface 12, and the third adhesive sheet 23' is adhered to the lower right side of the cup body inner surface 12. Of course, the positions of the first adhesive sheet 21', the second adhesive sheet 22' and the third adhesive sheet 23' are not limited to this. Their positions can be swapped and their shapes can be adaptively changed as needed. For example, the first adhesive sheet 21' can be set on the right side of the inner surface 12 of the cup body, the second adhesive sheet 22' can be located on the upper left side of the inner surface 12 of the cup body, and the third adhesive sheet 23' can be located on the lower left side of the inner surface 12 of the cup body, and their shapes can be adaptively changed.

[0100] The first adhesive sheet 21', the second adhesive sheet 22' and the third adhesive sheet 23' are enclosed in the middle of the inner surface 12 of the cup body, and the middle of the enclosed area is hollowed out to form a nipple accommodating area 5' for accommodating the user's nipple and its surrounding sensitive parts. The nipple accommodating area 5' is connected to each perspiration and ventilation channel 4'.

[0101] In this embodiment, each protective layer 3' is adapted to the shape and size of each adhesive layer 2', and it includes three protective sheets, including a first protective sheet 31', a second protective sheet 32' and a third protective sheet 33'. Specifically, the shape and size of the first protective sheet 31' are adapted to the shape and size of the first adhesive sheet 21' and is pasted on the first adhesive sheet 21'; the shape and size of the second protective sheet 32' are adapted to the shape and size of the second adhesive sheet 22' and is pasted on the second adhesive sheet 22'; the shape and size of the third protective sheet 33' are adapted to the shape and size of the third adhesive sheet 23' and is pasted on the third adhesive sheet 23'.

[0102] In this embodiment, Figure 19As shown, the cup body 1 may be provided with a non-sticky area, a first sticky area, and a second sticky area as needed, and may even further be provided with a third sticky area. The stickiness of the first sticky area, the second sticky area, and the third sticky area are different, and the stickiness of the three sticky areas is different. At this time, the setting of the third sticky area is based on the two different sticky requirements of the first sticky area and the second sticky area, and provides the user with a total of up to three stickiness or three adhesive strength requirements. The area within the nipple accommodating area 5' and the area within the perspiration and ventilation channel 4' are set as non-sticky areas because the inner surface 12 of the cup body itself is non-sticky. The strength of the three sticky areas is relative, depending on which two sticky areas are compared, but the stickiness of the sticky area with the weakest stickiness among the three sticky areas still meets the requirements of multiple sticking to the chest. Since each adhesive layer 2' of this embodiment includes a first adhesive sheet 21', a second adhesive sheet 22' and a third adhesive sheet 23', the settings of the first adhesive area, the second adhesive area and the third adhesive area can be adaptively adjusted between the three adhesive sheets 21', the second adhesive sheet 22' and the third adhesive sheet 23' as needed. Any adhesive sheet can be set as the first adhesive area, the second adhesive area or the third adhesive area as needed, but at least two adhesive areas with different strengths are provided on the three adhesive sheets, or in other words, there are at least two adhesive properties with different strengths on the three adhesive sheets. For example, the first adhesive sheet 21' is set as the second adhesive area, the second adhesive sheet 22' is set as the first adhesive area, and the third adhesive sheet 23' is set as the first adhesive area or the third adhesive area; or the first adhesive sheet 21' is set as the second adhesive area, the second adhesive sheet 22' is set as the third adhesive area, and the third adhesive sheet 23' is set as the first adhesive area; or the first adhesive sheet 21' is set as the second adhesive area, the second adhesive sheet 22' is set as the third adhesive area, and the third adhesive sheet 23' is set as the first adhesive area; etc. Of course, the arrangement of the first adhesive area, the second adhesive area, and the third adhesive area is not limited to this, but the three adhesive sheets can be provided with at least two adhesive areas or at least two types of adhesiveness, and at most three adhesive areas or at most three types of adhesiveness. When the cup body 1 is provided with the first adhesive area, the second adhesive area and the third adhesive area, the first adhesive sheet 21', the second adhesive sheet 22' and the third adhesive sheet 23' are respectively set as the first adhesive area, the second adhesive area and the third adhesive area.By setting the first adhesive area and the second adhesive area with different adhesive strengths in the range of the cup body 1 as needed, and even further setting a third adhesive area, since the adhesive force exerted on the chest by the adhesive area with stronger adhesiveness is different from the adhesive force exerted on the chest by the adhesive area with weaker adhesiveness, differentiated and different adhesive forces can be provided for different areas of the user's chest, so that the chest is under the action of different adhesive forces, so that the chest patch of this embodiment can give the user's chest a suitable lifting force or adhesive force that is locally different when used. After wearing, the chest patch has a good effect of gathering the chest, and the chest patch also has a good effect of lifting the chest or preventing the chest from sagging.

[0103] The parts associated with the aforementioned differences may be adaptively adjusted according to adaptability requirements. Parts that do not require adaptive adjustment or other undescribed parts are the same as those in the first embodiment and will not be described in detail.

[0104] 3. The third embodiment of the present utility model

[0105] The third embodiment of the present utility model is shown in Figures 16 to Figure 18 The third embodiment is basically the same as the first embodiment, and also includes a cup body 1, N layers of adhesive layers 2" and N layers of protective layers 3". The main difference is that each adhesive layer 2" includes four adhesive sheets, including a first adhesive sheet 21", a second adhesive sheet 22", a third adhesive sheet 23" and a fourth adhesive sheet 24". The first adhesive sheet 21" and the second adhesive sheet 22" are spaced apart at an appropriate distance to form a perspiration and ventilation channel 4". The second adhesive sheet 22 and the third adhesive sheet 23 are spaced apart at an appropriate distance to form a perspiration and ventilation channel 4". The third adhesive sheet 23" and the fourth adhesive sheet 24" are spaced apart at an appropriate distance to form a perspiration and ventilation channel 4". The sweat-wicking and ventilation channels 4" for perspiration and ventilation are formed, and the fourth adhesive sheet 24" is spaced appropriately from the first adhesive sheet 21" to form a sweat-wicking and ventilation channel 4". In this embodiment, the first adhesive sheet 21" is adhered to the left side of the inner surface 12 of the cup body, the second adhesive sheet 22" is adhered to the upper side of the inner surface 12 of the cup body, the third adhesive sheet 23" is adhered to the right side of the inner surface 12 of the cup body, and the fourth adhesive sheet 24" is adhered to the lower side of the inner surface 12 of the cup body. Of course, the positions and shapes of the first adhesive sheet 21", the second adhesive sheet 22", the third adhesive sheet 23" and the fourth adhesive sheet 24" are not limited to this, and their positions can be swapped and their shapes can be adaptively adjusted as needed.

[0106] The first adhesive sheet 21", the second adhesive sheet 22", the third adhesive sheet 23" and the fourth adhesive sheet 24" are located in the middle of the inner surface 12 of the cup body to form an enclosed state, and the middle of the enclosed area is hollowed out to form a nipple accommodating area 5" for accommodating the user's nipple and its surrounding sensitive parts. The nipple accommodating area 5" is connected to each perspiration and ventilation channel 4".

[0107] Each protective layer 3" in this embodiment is adapted to the shape and size of each adhesive layer 2", and it includes four protective sheets, including a first protective sheet 31", a second protective sheet 32", a third protective sheet 33" and a fourth protective sheet 34". Specifically, the shape and size of the first protective sheet 31" are adapted to the shape and size of the first adhesive sheet 21" and is pasted on the first adhesive sheet 21"; the shape and size of the second protective sheet 32" are adapted to the shape and size of the second adhesive sheet 22" and is pasted on the second adhesive sheet 22"; the shape and size of the third protective sheet 33" are adapted to the shape and size of the third adhesive sheet 23" and is pasted on the third adhesive sheet 23'; the shape and size of the fourth protective sheet 34" are adapted to the shape and size of the fourth adhesive sheet 24" and is pasted on the fourth adhesive sheet 24".

[0108] In this embodiment, Figure 20As shown, the cup body 1 may be provided with a non-adhesive area, a first adhesive area, a second adhesive area, and even a third adhesive area as needed. The first, second, and third adhesive areas are described in detail in the second embodiment and will not be repeated here. The area within the nipple accommodating area 5" and the area within the perspiration and ventilation channel 4" are non-adhesive areas because the cup inner surface 12 itself is non-adhesive. Since the adhesive layer 2" of this embodiment includes a first adhesive sheet 21", a second adhesive sheet 22", a third adhesive sheet 23" and a fourth adhesive sheet 24", the setting areas of the first adhesive area, the second adhesive area and the third adhesive area can be adaptively adjusted and set between the first adhesive sheet 21", the second adhesive sheet 22", the third adhesive sheet 23" and the fourth adhesive sheet 24" as needed. Any adhesive sheet can be set as the first adhesive area, the second adhesive area or the third adhesive area as needed. For example, the first adhesive sheet 21" is set as the second adhesive area, the second adhesive sheet 22" is set as the first adhesive area, the third adhesive sheet 23" is set as the first adhesive area or the third adhesive area, and the fourth adhesive sheet 24" is set as the second adhesive area or the third adhesive area; or, the first adhesive sheet 21" is set as the third adhesive area, the second adhesive sheet 22" is set as the second adhesive area, the third adhesive sheet 23" is set as the first adhesive area, and the fourth adhesive sheet 24" is set as the second adhesive area. or, the first adhesive sheet 21 "is set as the first adhesive area, the second adhesive sheet 22 "is set as the first adhesive area, the third adhesive sheet 23 "is set as the third adhesive area or the second adhesive area, the fourth adhesive sheet 24 " Set as a third adhesive area or a second adhesive area; and so on. Of course, the arrangement of the first adhesive area, the second adhesive area, and the third adhesive area is not limited to this, but the four adhesive sheets can be provided with at least two adhesive areas or at least two types of adhesive, and up to three adhesive areas or up to three types of adhesive. By setting the first adhesive area and the second adhesive area, or even further providing a third adhesive area, with different adhesive strengths as needed in different regions within the cup body 1, the adhesive force exerted on the chest by the stronger adhesive area is different from the adhesive force exerted on the chest by the weaker adhesive area. This can provide differentiated and different adhesive forces to different areas of the user's chest, thereby subjecting the chest to different adhesive forces. When used, the bra patch of this embodiment provides the user with locally differentiated and appropriate lifting or adhesive forces on the chest. When worn, the bra patch has the good effect of gathering the breasts together, and also has the good effect of lifting the breasts or preventing breast sagging.

[0109] It can be understood that as another alternative to this embodiment, without considering the number of manufacturing process steps, since the adhesive layer 2" includes four adhesive sheets, at least two of the four adhesive areas, namely the first adhesive area, the second adhesive area, the third adhesive area and the fourth adhesive area, can be provided within the cup body 1 as needed. The viscosity of the first adhesive area, the second adhesive area, the third adhesive area and the fourth adhesive area are different, and their viscosity strengths are different. Each adhesive sheet can be set as any one of the first adhesive area, the second adhesive area, the third adhesive area and the fourth adhesive area as needed, but the four adhesive sheets are provided with at least two adhesive areas or at least two types of viscosity, and at most four adhesive areas or at most four types of viscosity, which means that the user is provided with the most There are four types of viscosity or up to four types of adhesive strength to choose from. Users can choose to match two, three or even four types of viscosity on the four adhesive sheets of a chest patch to adapt to and match the different adhesive strength requirements of different users. When the cup body 1 is provided with four adhesive areas, namely the first adhesive area, the second adhesive area, the third adhesive area and the fourth adhesive area, the first adhesive layer, the second adhesive layer, the third adhesive layer and the fourth adhesive layer are respectively set as the first adhesive area, the second adhesive area, the third adhesive area and the fourth adhesive area. The strength of the four adhesive areas is relative, depending on which two adhesive areas are compared. However, the adhesive area with the weakest viscosity among the four adhesive areas still has the viscosity that meets the requirements for multiple adhesion to the chest.

[0110] The parts associated with the aforementioned differences may be adaptively adjusted according to adaptability requirements. Parts that do not require adaptive adjustment or other undescribed parts are the same as those in the second embodiment and will not be described in detail.

[0111] 4. Fourth embodiment of the present utility model

[0112] The fourth embodiment of the present utility model, see Figures 21 to 24 The fourth embodiment also includes a pair of symmetrically arranged cups and a connecting device 7 located between the pair of cups for connecting the cups. Each cup also includes a cup body 1. The inner surface 12 of the cup body 1 is also provided with N adhesive layers 2A and N protective layers 3A. The N adhesive layers 2A and N protective layers 3A are integrally formed and disposed at the outer edge of the inner surface 12 of the cup body. Each adhesive layer 2A is identical, and each protective layer 3A is identical, with the shape of the protective layer 3A matching that of the adhesive layer 2A. For ease of illustration, N in this embodiment is 3, and the cup body 1 is provided with three adhesive layers 2A and three protective layers 3A.

[0113] In this embodiment, each adhesive layer 2A is in the form of an elongated strip. Because each protective layer 3A matches the shape and size of each adhesive layer 2A, each protective layer 3A is in the form of an elongated strip and is adhered to the adhesive layer 2A. The outer edge of the protective layer 3A is a suitable distance d2 from the outer edge of the cup body 1. The size of the protective layer 3A can be slightly larger than or equal to the size of the adhesive layer 2A so that the protective layer 3A completely covers the adhesive layer 2A to protect it. In this embodiment, the size of the protective layer 3A is equal to that of the adhesive layer 2A and is a thin sheet structure with appropriate thickness and flexibility.

[0114] Each adhesive layer 2A and each protective layer 3A extends along the outer edge of the inner surface of the cup body and encloses a nipple accommodating area 5A for accommodating the user's nipple and the sensitive parts around it, and an opening is left at one end of the enclosed area to form a sweat-wicking and breathable channel 4A, one end of the sweat-wicking and breathable channel 4A is connected to the nipple accommodating area 5A and the other end extends to the outer edge of the cup body 1 and is connected to the outside of the cup body 1; N layers of adhesive layers 2A and N layers of protective layers 3A form a whole, N layers of adhesive layers 2A and N layers of protective layers 3A extend along the outer edge of the inner surface of the cup body and enclose a nipple accommodating area 5A for accommodating the user's nipple and the sensitive parts around it, and an opening is left at one end of the enclosed area to form a sweat-wicking and breathable channel 4A, one end of the sweat-wicking and breathable channel 4A is connected to the nipple accommodating area 5A and the other end extends to the outer edge of the cup body 1 and is connected to the outside of the cup body 1; so that the cup body 1 has good breathability. The overall shape of the N-layer adhesive layer 2A and the N-layer protective layer 3A is also long strips, and both the N-layer adhesive layer 2A and the N-layer protective layer 3A have appropriate width and length.

[0115] like Figure 24 As shown, because the adhesive layer 2A is an elongated strip with an appropriate length and width, it has become a non-integral elongated strip structure compared to the conventional single-piece adhesive sheet. Furthermore, the adhesive layer 2A also encloses the perspiration-wicking and ventilation channels 4A and the nipple-receiving area 5A, significantly reducing the likelihood of wrinkles during use. To prevent or further reduce wrinkles in the adhesive layer, particularly at the curved or wider portions of the adhesive layer, several anti-wrinkle notches 29 are pre-defined at the curved or wider portions of the adhesive layer 2A. This significantly reduces the likelihood of wrinkles in the adhesive layer, particularly at the curved portions, during use. Preferably, the anti-wrinkle notches 29 are V-shaped, U-shaped, or arc-shaped. As will be appreciated, since each protective layer 3A matches the shape and size of each adhesive layer 2A, several anti-wrinkle notches 39 are also defined at the curved or wider portions of the protective layer 3A, corresponding to the locations of the adhesive layer 2A. Preferably, the anti-wrinkle notch 39 is the same as the anti-wrinkle notch, and its shape is also V-shaped, U-shaped or arc-shaped.

[0116] like Figure 24 As shown, since the adhesive layer 2A itself is sticky, in order to facilitate the user to tear off the adhesive layer 2A smoothly after the adhesive layer 2A has been used for a maximum number of times or has lost its stickiness, a tearing auxiliary portion 9 can be pre-set at the upper edge of the protective layer 3A. When in use, the user can use the tearing auxiliary portion 9 to easily tear off the protective layer 3A to be torn off, and by the way, tear off the adhesive layer 2A stuck on the protective layer 3A.

[0117] In this embodiment, Figure 22 As shown, each adhesive layer 2A and each protective layer 3A have the same shape, which is U-shaped. The width d3 of the adhesive layer 2A is 2.75 cm, the distance d1 between the outer edge of the adhesive layer 2A and the outer edge of the cup body 1 is 0.25 cm, and the distance d2 between the outer edge of the protective layer 3A and the outer edge of the cup body 1 is 0.25 cm.

[0118] The parts associated with the aforementioned differences may be adaptively adjusted according to adaptability requirements. Parts that do not require adaptive adjustment or other undescribed parts are the same as those in the first embodiment and will not be described in detail.

[0119] V. Fifth embodiment of the utility model

[0120] The fifth embodiment of the utility model, see Figure 25 The fifth embodiment is basically the same as the fourth embodiment. The fifth embodiment also includes a pair of cups symmetrically arranged on the left and right and a connecting device 7 located in the middle of the pair of cups for connecting the pair of cups. Each cup also includes a cup body 1. The inner surface 12 of the cup body 1 is also provided with N layers of adhesive layers 2B and N layers of protective layers 3B. The N layers of adhesive layers 2B and the N layers of protective layers 3B are integrated and arranged at the outer edge of the inner surface 12 of the cup body. Each layer of adhesive layer 2B is the same, each layer of protective layer 3B is the same, and the shape of each layer of protective layer 3B is adapted to the shape of each layer of adhesive layer 2B. Each layer of adhesive layer 2B in this embodiment includes two adhesive sheets, such as Figure 25 As shown, each adhesive layer 2B includes a first adhesive sheet 21B and a second adhesive sheet 22B. The first adhesive sheet 21B and the second adhesive sheet 22B are located on the upper and lower sides of the inner surface 12 of the cup body, respectively, and are spaced appropriately apart to form a perspiration and ventilation channel 4B for perspiration and ventilation. The first adhesive sheet 21B and the second adhesive sheet 22B form a closed area in the middle of the inner surface 12 of the cup body, and the center of the closed area is hollowed out to form a nipple receiving area 5B for accommodating the user's nipple and surrounding sensitive areas. The nipple receiving area 5B is interconnected with the perspiration and ventilation channel 4B. The adhesive layer 2B and the protective layer 3B are both elongated in shape, and both the adhesive layer 2A and the protective layer 3A have appropriate width and length.

[0121] In this embodiment, each protective layer 3B matches the shape and size of each adhesive layer 2B. Each protective layer 3 comprises two protective sheets: a first protective sheet 31B and a second protective sheet 32B. The shape and size of the first protective sheet 31B matches the shape and size of the first adhesive sheet 21B and is affixed to the first adhesive sheet 21B; the shape and size of the second protective sheet 32B matches the shape and size of the second adhesive sheet 22B and is affixed to the second adhesive sheet 22B. The outer edge of the protective layer 3B is a suitable distance d2 from the outer edge of the cup body 1. The size of the protective layer 3B is greater than or equal to the size of the adhesive layer 2B, allowing the protective layer 3B to completely cover the adhesive layer 2B to protect it. The protective layer 3B is a thin sheet structure with appropriate thickness and flexibility.

[0122] Because the adhesive layer 2B is elongated and has an appropriate length and width, it has become a non-integral elongated structure, unlike the single-piece adhesive sheet of the prior art. In other words, because the first adhesive sheet 21B or the second adhesive sheet 22B of the adhesive layer 2B has been split into two separate adhesive sheets, and the adhesive layer 2B also encloses the perspiration-wicking and ventilation channels 4B and the nipple-accommodating area 5B, to prevent or further reduce wrinkles in the adhesive layer, particularly at the curved or wider portions of the adhesive layer, during use, a plurality of wrinkle-preventing notches 29 are pre-defined in the curved or wider portions of the adhesive layer 2B. This significantly reduces the likelihood of wrinkles in the adhesive layer, particularly at the curved portions, during use. Preferably, the wrinkle-preventing notches 29 are V-shaped, U-shaped, or arc-shaped. As will be appreciated, since each protective layer 3B is adapted to the shape and size of each adhesive layer 2B, a plurality of wrinkle-preventing notches 39 are correspondingly provided at the curved or wider portions of the protective layer 3B corresponding to the adhesive layer 2B. Preferably, the wrinkle-preventing notches 39 are similar to the wrinkle-preventing notches, and are also V-shaped, U-shaped, or arc-shaped.

[0123] Since the adhesive layer 2B itself is sticky, in order to facilitate the user to tear off the adhesive layer 2B smoothly after the adhesive layer 2B has been used a maximum number of times or has lost its stickiness, a tearing-off auxiliary portion 9 can be pre-set at the upper edge of the protective layer 3B. During use, the user can use the tearing-off auxiliary portion 9 to easily tear off the protective layer 3B to be torn off, and by the way, tear off the adhesive layer 2B stuck on the protective layer 3B.

[0124] Since each adhesive layer 2B includes a first adhesive sheet 21B and a second adhesive sheet 22B, it is understandable that the first adhesive sheet 21B and the second adhesive sheet 22B can be respectively configured as a first adhesive area and a second adhesive area, and the first adhesive area and the second adhesive area have different adhesive strengths. For details, please refer to the first embodiment and will not be repeated here. By setting the first adhesive area and the second adhesive area with different adhesive strengths in different regions as needed within the cup body 1, since the adhesive force exerted on the chest by the stronger adhesive area is different from the adhesive force exerted on the chest by the weaker adhesive area, it is possible to provide differentiated and different adhesive forces to different areas of the user's chest, so that the chest is subjected to different adhesive forces. When used, the bra patch of this embodiment provides the user's chest with a suitable lifting force or adhesive force that is differentiated by the local difference. After being worn, the bra patch has a good effect of gathering the breasts, and also has a good effect of lifting the breasts or preventing breast sagging.

[0125] Since each adhesive layer 2B includes a first adhesive sheet 21B and a second adhesive sheet 22B, it can be understood that as another implementation of this embodiment, the first adhesive sheet 21B and the second adhesive sheet 22B can also be located on the left and right sides of the inner surface 12 of the cup body, respectively. At this time, it is basically the same as the first embodiment and can be adjusted to suit the needs of suitability. Please refer to the first embodiment for details and will not be repeated here.

[0126] In this embodiment, preferably, each adhesive layer 2B and each protective layer 3B have the same shape, which is U-shaped. The width d3 of the adhesive layer 2B is 2.75 cm, the distance d1 between the outer edge of the adhesive layer 2B and the outer edge of the cup body 1 is 0.25 cm, and the distance d2 between the outer edge of the protective layer 3B and the outer edge of the cup body 1 is 0.25 cm.

[0127] The parts associated with the aforementioned differences can be adaptively adjusted according to adaptability requirements. Parts that do not require adaptive adjustment or other undescribed parts are the same as the first and fourth embodiments and will not be described in detail.
