Description

Technical Field

[0001] The utility model belongs to the field of underwear, and particularly relates to a breast sticker, in particular to a breast sticker with a non-integral paste layer. Background Art

[0002] A breast sticker generally includes a cup body, a paste layer and a protective layer. The paste layer has a certain adhesiveness and is adhered to the inner surface of the cup body. The protective layer is used to protect the paste layer and cover the paste layer to prevent the paste layer from sticking to impurities such as dust. In the prior art, the paste layer is generally directly formed into an integral structure by manual brushing of glue or hot melting and adhered to the inner surface of the cup body as a whole. The integral paste layer is the same as or substantially the same as the shape and size of the inner surface of the cup body, and substantially completely covers the entire inner surface of the cup body. When in use, the protective layer covering the paste layer needs to be torn off first, and the breast sticker is adhered to the user's chest by using the adhesiveness of the paste layer. The paste layer covers the chest and completely encloses or substantially encloses the covered area of the chest. In addition, the paste layer in the prior art is generally integral and has the same adhesiveness. Since the adhesiveness of the whole paste layer is the same, the adhesive force provided to the chest is also the same. Therefore, the breast stickers with this structure in the prior art generally have the following problems:

[0003] 1. Since the paste layer is adhered to the inner surface of the cup body as a whole in an integral structure, and the cup body is an uneven structure that is convex on the outside and concave on the inside in order to fit the chest, when the paste layer is adhered to the concave inner surface of the cup body in an integral form, the paste layer itself often has the problem of wrinkles. Since the paste layer itself has adhesiveness, the surfaces of the paste layer at the wrinkles are bonded to each other and are not easily separated. If the wrinkles are flattened or forcibly separated, the paste layer may be torn to form holes or be damaged locally, which will affect the service life of the paste layer and the breast sticker.

[0004] 2. Because of the wrinkles, the surface of the paste layer has protrusions, or tears, holes or local damage occur, and the user will feel a sense of foreign object pressing or other discomfort at the corresponding part of the chest when using the breast sticker.

[0005] 3. Since the paste layer is adhered to the cup body as a whole, the paste layer sometimes sticks to the female nipple and its surrounding sensitive parts. The skin of the nipple and its surrounding sensitive parts is easily injured when torn. If torn forcefully, it may even damage the skin of the nipple and its surrounding sensitive parts.

[0006] 4. 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 layer and accelerate the wear of the adhesive layer.

[0007] 5. When in use, 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 covered by the adhesive layer and is almost airtight to the outside world. The airtightness can easily lead to chest sweating.

[0008] 6. Since the adhesive layer has the same viscosity, it cannot adapt to and match the different adhesive force requirements of different users. For example, some users need the bra patch to provide appropriate lifting force or adhesive force for local differences in 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 anti-sagging effect. Utility Model Content

[0009] In order to solve the above technical problems, the utility model provides a breast patch, including a cup body and an adhesive layer, the cup body including an inner surface of the cup body concave inward, and the adhesive layer is adhered to the inner surface of the cup body; the adhesive layer includes at least two adhesive sheets, and adjacent two adhesive sheets are spaced apart to form a number of perspiration and ventilation channels, each adhesive sheet is adhered to the inner surface 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 for accommodating the nipple and its surrounding sensitive parts, one end of each perspiration and ventilation channel is connected to the nipple accommodating area, and the other end extends to the outer edge of the cup body and is connected to the outside of the cup body.

[0010] Furthermore, it also includes a protective layer that is detachably attached to the adhesive layer, and the shape and size of the protective layer are adapted to those of the adhesive layer.

[0011] Furthermore, the adhesive layer includes two adhesive sheets, which include a first adhesive sheet and a second adhesive sheet, which are respectively adhered to the left and right sides of the inner surface of the cup body; correspondingly, the protective layer includes two protective sheets, which include a first protective sheet and a second protective sheet, the first protective sheet is adapted to the first adhesive sheet and is detachably adhered to the first adhesive sheet, and the second protective sheet is adapted to the second adhesive sheet and is detachably adhered to the second adhesive sheet.

[0013] Further, the adhesive layer includes four adhesive sheets, including a first adhesive sheet, a second adhesive sheet, a third adhesive sheet, and a fourth adhesive sheet. The first, second, third, and fourth adhesive sheets are respectively adhered to the left, upper, right, and lower sides of the inner surface of the cup body; correspondingly, the protective layer includes four protective sheets, including a first protective sheet, a second protective sheet, a third protective sheet, and a fourth protective sheet. The first protective sheet is adapted to the first adhesive sheet and detachably adhered to the first adhesive sheet, the second protective sheet is adapted to the second adhesive sheet and detachably adhered to the second adhesive sheet, the third protective sheet is adapted to the third adhesive sheet and detachably adhered to the third adhesive sheet, and the fourth protective sheet is adapted to the fourth adhesive sheet and detachably adhered to the fourth adhesive sheet.

[0014] Further, the sweat-venting and breathable channel includes a channel opening and a channel body. The width of the channel openings at both ends of the sweat-venting and breathable channel is greater than the width of the channel body; when in use, one channel opening of the sweat-venting and breathable channel faces upward, and the other channel opening faces downward.

[0015] Further, the adhesive layer is a double-sided adhesive structure with two layers. One layer is a cup body adhesive layer for adhering to the inner surface of the cup body, and the other layer is a skin-friendly adhesive layer for adhering to the protective layer. The cup body adhesive layer and the skin-friendly adhesive layer are adhered together to form an integral body; alternatively, the adhesive layer is a double-sided adhesive structure with three layers. One layer is a cup body adhesive layer for adhering to the cup body, the other layer is a skin-friendly adhesive layer for adhering to the protective layer, and there is also an intermediate layer between the two. The two sides of this intermediate layer are respectively adhered to the cup body adhesive layer and the skin-friendly adhesive layer to form an integral body.

[0016] Further, the outer edge of the adhesive layer is at a set distance from the outer edge of the cup body.

[0017] Further, the shape of the nipple accommodating area is oval. The major axis a of the oval nipple accommodating area is 7 cm, and the minor axis b is 4 cm.

[0018] Further, the length H of the cup body is 14.5 cm, and the width W of the cup body is 11 cm.

[0019] The breast patch of the present utility model has the following advantages or beneficial effects:

[0020] 1. In the breast patch of the present utility model, the adhesive layer is split into a non-integral structure including at least two adhesive sheets, which avoids or reduces the phenomenon that the adhesive layer of the integral structure is prone to wrinkles during use, thereby avoiding or reducing the phenomenon that the adhesive layer has holes or local damage due to wrinkles, thereby prolonging the service life of the adhesive layer, and further prolonging the service life of the cup.

[0021] 2. Because the appearance of wrinkles in the adhesive layer is avoided or reduced, the adhesive on the surface of the adhesive layer can be kept relatively flat and smooth during use, and the user will not have a foreign body pressing feeling or other discomfort caused by the protrusion at the wrinkled part during use.

[0022] 3. Since the adhesive layer is split into a non-integral structure including at least two adhesive sheets and is pasted on the cup body, and there is an appropriate distance between adjacent two adhesive sheets and a nipple accommodating area for accommodating the nipple is left, it is avoided that the adhesive layer adheres to the skin of the female nipple and its surrounding sensitive parts, that is, the probability of the adhesive layer damaging the skin of the nipple and its surrounding sensitive parts is avoided or reduced, and the use is safer.

[0023] 4. Since the adhesive layer is split into at least two adhesive sheets and is pasted on the cup body, and there is an appropriate distance between adjacent two adhesive sheets and a nipple accommodating area for accommodating the nipple and several sweat exhausting and breathable channels for sweating are formed, the sweat exhausting and breathable channels extend from the nipple accommodating area to the edge of the cup body to make the inside and outside of the cup body communicate with each other, and the sweat will drain out along the sweat exhausting and breathable channels after sweating; because there are sweat exhausting and breathable channels, the stimulation of the skin by sweat and the discomfort caused to the user are avoided or reduced. Due to the setting of the sweat exhausting and breathable channels and the nipple accommodating area, it is also convenient for the cup body to dry quickly after cleaning.

[0024] 5. Since the protective layer is adapted to the adhesive layer, the protective layer is also split into at least two protective sheets and pasted on the adhesive layer. The non-integral protective layer structure also makes the sweat exhausting and breathable channels and the nipple accommodating area not be covered when it covers the adhesive layer, which is more conducive to the air permeability inside and outside the cup body and is convenient for the cup body to dry quickly after cleaning. At the same time, the outer edge of the adhesive layer is at an appropriate distance from the outer edge of the cup body, and the protective layer completely covers the adhesive layer inside. The protective layer protects the adhesive on the adhesive layer from being soiled or damaged. The use of this protective layer also makes the viscosity on the surface of the adhesive layer more persistent, the number of uses more, and the service life longer.

[0025] 6. Since the adhesive layer is split into at least two adhesive sheets with an appropriate distance between adjacent adhesive sheets to form a sweat-venting channel, the inside of the breast patch is in communication and breathable with the outside of the breast patch, and it has good breathability.

[0026] 7. The widths of the channel openings at both ends of the sweat-venting channel are larger than the width of the channel body, which facilitates the ventilation between the inside and the outside of the breast patch and also facilitates the discharge of sweat.

[0027] 8. In the use state, one end of the sweat-venting channel has its channel opening facing upward and the other end has its channel opening facing downward, so that the sweat discharged by the user naturally flows downward for easy sweating.

[0028] 9. Since the adhesive layer can also be provided on the inner surface edge of the cup body and the adhesive layer is strip-shaped and extends along the inner surface edge of the cup body to form a nipple accommodating area and a sweat-venting channel, this adhesive layer is also not a whole-piece structure, and the breast patch using this adhesive layer also has good breathability.

[0029] 10. Since there are at least two adhesive areas within the cup body range and at least two of the adhesive areas have different adhesive strengths, it can adapt to and match the different adhesive force requirements of different users. The breast patch can give appropriate lifting force or adhesive force to different parts of the user's chest. After wearing the breast patch, it has a good effect of gathering the chest, and the breast patch also has a good effect of lifting the chest or preventing the chest from sagging.

[0061] In view of the above technical problems existing in the prior art, the present utility model provides a breast patch to solve the above technical problems. The technical solution of the breast patch will be elaborated in detail below in combination with the specific implementation manners.

[0062] I. The first embodiment of the present utility model

[0063] A breast patch of the first embodiment of the present utility model is as follows. For details, see the Figures 1 to 10 :

[0064] The breast patch of the first embodiment includes a pair of cup-shaped covers symmetrically arranged left and right and a connecting device 7 located in the middle of the pair of cup-shaped covers for connecting the pair of cup-shaped covers. Each cup-shaped cover includes a cup body 1, an adhesive layer 2 and a protective layer 3. For the convenience of description, Figure 2Taking the left cup as the orientation reference, the cup body 1 includes a cup outer surface 11 that bulges outward and a cup inner surface 12 that depresses inward. The adhesive layer 2 is pasted on the cup inner surface 12. The cup inner surface 12 itself has no adhesiveness and is made of existing soft and skin-friendly materials, such as cloth, silicone rubber material, etc. The adhesive layer 2 is split into at least two adhesive patches and consists of at least two separate adhesive patches. The adhesive layer 2 adopts a non-integral structure to distinguish it from the integral structure of the prior art. The adhesive layer 2 of this embodiment includes two adhesive patches. In the Figure 2 direction shown, it includes a first adhesive patch 21 and a second adhesive patch 22. The first adhesive patch 21 and the second adhesive patch 22 are respectively located on the left and right sides of the cup inner surface 12, and an appropriate distance is set between them to form a sweat-venting and breathable channel 4 for sweating and ventilation; a surrounding state is formed between the first adhesive patch 21 and the second adhesive patch 22 in the middle of the cup inner surface 12, and the middle of the surrounding 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 and the sweat-venting and breathable channel 4 are both interconnected. Since each adhesive patch is pasted on the cup inner surface 12, there is a sweat-venting and breathable channel 4 between adjacent two adhesive patches, making the distance between them appropriate, and there is also a nipple accommodating area 5 in the middle of the cup inner surface 12, making the distance between them appropriate. This non-integral adhesive layer is not easy to produce wrinkles during use compared with the integral adhesive layer. Since the cup inner surface 12 has no adhesiveness, when the breast sticker is attached to the user's chest, the cup inner surface 12 will not stick to the user's nipple and its surrounding sensitive parts. At the same time, since there is no adhesive layer 2 in the nipple accommodating area 5, it can be avoided that the adhesive layer 2 sticks to the user's nipple and its surrounding sensitive parts, that is, it can avoid or reduce the damage to the nipple and its surrounding sensitive parts when tearing off the adhesive layer 2, and the use is more comfortable and safe.

[0065] In this embodiment, in the Figure 2 direction shown, the sweat-venting and breathable channel 4 includes a channel opening 401 and a channel main body 402. During use, preferably, one channel opening 401 at one end of the sweat-venting and breathable channel 4 faces upward, and the other channel opening 401 at the other end faces downward, so that the sweat discharged by the user can flow down naturally for easy sweating, and the widths of the channel openings 401 at both ends of the sweat-venting and breathable channel 4 are both greater than the width d of the channel main body 402 (as shown in Figure 8 ), which is also convenient for sweating and ventilation. The nipple accommodating area 5 is generally circular or oval. It can be understood that the shape of the nipple accommodating area 5 is not limited to this and can be set into other different shapes according to needs.

[0066] Such as Figure 9As shown, the adhesive layer 2 can adopt a flexible double-sided adhesive structure, which includes an intermediate layer 203, a cup adhesive layer 201 adhered to one side of the intermediate layer 203, and a skin-friendly adhesive layer 202 adhered to the other side of the intermediate layer 203. The intermediate layer 203 serves as a base material, having a certain softness, waterproofness, and breathability. The intermediate layer and the cup adhesive layer 201 and the skin-friendly adhesive layer 202 adhered to its two sides form an integral body and have an appropriate thickness. The intermediate layer 203 is an elastic film layer, and this elastic film layer can be selected from a TPU layer, a TPR layer (TPR rubber material), a PTE layer (PTE rubber material), and a silicone rubber film. Preferably, the elastic film layer is selected as the TPU layer, and TPU adhesives can bond a variety of materials. The cup adhesive layer 201 is used to adhere to the cup 1. Specifically, the cup adhesive layer 201 is adhered to the inner surface 12 of the cup and is not easily torn off. The cup adhesive layer 201 can adopt 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, or acrylic adhesive. The cup adhesive layer 201 has good adhesiveness and peel strength, so that it is not easily detached and displaced when adhered to the inner surface 12 of the cup. The skin-friendly adhesive layer 202 is adhered to the other side of the intermediate layer 203. The skin-friendly adhesive layer 202 is made of an environmentally friendly adhesive material and has a skin-friendly effect, and is used to adhere the breast pad to the user's skin. Preferably, the skin-friendly adhesive layer 202 can be made of a silicone gel material, such as platinum addition-cured silicone gel or condensation-cured silicone gel. The adhesiveness of the cup adhesive layer 201 is greater than that of the skin-friendly adhesive layer 202, so that the adhesion between the cup adhesive layer 201 and the inner surface 12 of the cup is greater than the adhesion between the skin-friendly adhesive layer 202 and the user's skin.

[0067] It can be understood that, as Figure 10 shown, another double-sided adhesive structure adopted by the adhesive layer 2 has only one cup adhesive layer 201 and one skin-friendly adhesive layer 202 adhered to each other, that is, this structure is a double-sided adhesive structure without the intermediate layer 203. Its cup adhesive layer 201 is directly adhered to the skin-friendly adhesive layer 202 to form an integral body and has an appropriate thickness. It uses the cup adhesive layer 201 to adhere to the cup 1, and it uses the skin-friendly adhesive layer 202 to detachably adhere to the protective layer 3.

[0068] The outer edge of the adhesive layer 2 is at a set distance d1 from the outer edge of the cup 1 (as Figure 8 shown), and the size of the adhesive layer 2 is slightly smaller than the size of the cup 1 to prevent the outer edge of the adhesive layer 2 from protruding beyond the outer edge of the cup 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, and sticking to dust and impurities will also dirty the adhesive layer and is not beautiful.

[0069] The protective layer 3 is detachably attached to the adhesive layer 2 to protect the adhesive layer 2. When the chest patch is in use, the protective layer 3 is removed from the adhesive layer 2, and the chest patch can be attached to the user's chest using the adhesive strength of the adhesive layer 2. When the chest patch is not in use, the protective layer 3 is attached to the adhesive layer 2. This protects the adhesive on the surface of the adhesive layer 2 from getting dirty or damaged. Furthermore, the protective layer 3 also makes the adhesive strength of the adhesive layer 2 more durable, allowing for more frequent uses and a longer lifespan. After use, the surface of the adhesive layer 2 can be cleaned, and the protective layer 3 is then attached to the adhesive layer 2 to protect it.

[0070] The protective layer 3 is a release layer, which can be made of release paper or release film. The base material of the release layer can be any one of PET, PE, OPP, PVC, PS, PP, PET-G, or a composite material containing one or two of these materials. The release layer can also be made of aluminum foil or paper pulp coating.

[0071] 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 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.

[0072] It is understandable that the structure of the protective layer is not limited to this, and there are other alternative embodiments (not shown in the figure). For example, the protective layer of the alternative embodiment is set as a protective layer 3X (not shown in the figure). The protective layer 3X is different from the protective layer 3 of the first embodiment. The protective layer 3X is a whole piece structure. The shape and size of the protective layer 3X are adapted to the cup body 1. The outer contour size of the protective layer 3X is the same as or slightly smaller than the outer contour size of the cup body 1, but the outer contour size of the protective layer 3X is greater than or equal to the outer contour size of the adhesive layer 2, so that the protective layer 3X can completely cover the adhesive layer 2 to protect the adhesive layer 2. Of course, the protective layer 3X also completely covers the sweat-wicking and breathable channel 4 and the nipple accommodating area 5.

[0073] Since the adhesive layer in the prior art is generally a single-piece and has the same viscosity, the adhesive layer 2 of this embodiment includes two adhesive sheets, and the viscosities of these two adhesive sheets can of course be the same. Considering the differences in the chest sizes and shapes of different users, in order to adapt to and match the different adhesive force requirements of different users, for example, some users hope to have a good chest gathering effect after wearing the breast patch, some need the breast patch to give appropriate lifting force or adhesive force to a local area of the chest, and some need the breast patch to have a good effect of lifting the chest or preventing the chest from sagging. Therefore, as Figure 17 shown, within the range of the cup body 1 of the present utility model, a non-adhesive area, a first adhesive area and a second adhesive area are further provided. The viscosities of the two adhesive areas of the first adhesive area and the second adhesive area are different. For example, if the viscosity of the first adhesive area is stronger, then the viscosity of the second adhesive area is weaker. At this time, the viscosity of the first adhesive area is stronger than that of the second adhesive area, and vice versa. If the viscosity of the first adhesive area is weaker, then the viscosity of the second adhesive area is stronger. At this time, the viscosity of the first adhesive area is weaker than that of the second adhesive area. The setting of different viscosities of the first adhesive area and the second adhesive area provides at least two choices of viscosities or two adhesive force requirements for users. As Figure 17 shown, the first adhesive area and the second adhesive area are provided on the adhesive sheet of the adhesive layer 2, specifically on the corresponding areas of the skin-adhering adhesive layer 202 of the adhesive sheet. When producing the breast patch, the viscosities of the corresponding areas of the skin-adhering adhesive layer 202 have been pre-adjusted as required in advance. Although one of the first adhesive area and the second adhesive area is an adhesive area with a weaker viscosity, the viscosity of the adhesive area with a weaker viscosity still meets the requirement of being able to be repeatedly adhered to the chest. The areas within the range of the nipple accommodating area 5 and the areas within the range of the sweat-permeable and breathable channel 4 are non-adhesive areas due to the inner surface 12 of the cup body itself. In this embodiment, since the adhesive layer 2 includes a first adhesive sheet 21 and a second adhesive sheet 22, when the first adhesive sheet 21 is set as the first adhesive area, then the second adhesive sheet 22 is set as the second adhesive area; or the first adhesive sheet 21 is set as the second adhesive area, then the second adhesive sheet 22 is set as the first adhesive area. By separately setting the first adhesive area and the second adhesive area with different viscosities in the range of the cup body 1 as required, since the adhesive force generated by the adhesive area with a stronger viscosity on the chest is different from the adhesive force generated by the adhesive area with a weaker viscosity on the chest, it can provide different and different-strength adhesive forces for different areas of the user's chest, so that the chest is under the action of different adhesive forces, making the breast patch of this embodiment give appropriate lifting force or adhesive force to different parts of the user's chest during use, and having a good chest gathering effect after wearing the breast patch, and the breast patch also has a good effect of lifting the chest or preventing the chest from sagging.

[0074] In this embodiment, preferably, as Figure 8As shown in the figure, 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. 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 sweat-venting channel 4 is 1 cm. More preferably, the shape of the nipple accommodating area 5 is oval, the major axis a of the oval nipple accommodating area 5 is 7 cm, and the minor axis b is 4 cm. Of course, the sizes of the breast patch and its various components and functional areas can be adjusted and adapted as needed, and are not limited to this.

[0075] II. The second embodiment of the present utility model

[0076] For the second embodiment of the present utility model, see Figures 11 to 13 , the second embodiment is basically the same as the first embodiment, and it also includes a cup body 1, an adhesive layer 2' and a protective layer 3'. The main difference is that the adhesive layer 2' includes three adhesive patches, which include a first adhesive patch 21', a second adhesive patch 22' and a third adhesive patch 23'. A sweat-venting channel 4' for sweating and ventilation is formed by setting a proper distance between the first adhesive patch 21' and the second adhesive patch 22'. A sweat-venting channel 4' for sweating and ventilation is also formed by setting a proper distance between the second adhesive patch 22' and the third adhesive patch 23'. A sweat-venting channel 4' for sweating and ventilation is also formed by setting a proper distance between the third adhesive patch 23' and the first adhesive patch 21'. In this embodiment, the first adhesive patch 21' is pasted on the left side of the inner surface 12 of the cup body, the second adhesive patch 22' is pasted on the upper right side of the inner surface 12 of the cup body, and the third adhesive patch 23' is pasted on the lower right side of the inner surface 12 of the cup body. Of course, the positions of the first adhesive patch 21', the second adhesive patch 22' and the third adhesive patch 23' are not limited to this, and they can be swapped according to needs and the shapes can be adaptively changed. For example, the first adhesive patch 21' can be set on the right side of the inner surface 12 of the cup body, the second adhesive patch 22' can be located on the upper left side of the inner surface 12 of the cup body, and the third adhesive patch 23' is located on the lower left side of the inner surface 12 of the cup body, and its shape can be adaptively changed.

[0077] The first adhesive patch 21', the second adhesive patch 22' and the third adhesive patch 23' form an enclosed state in the middle of the inner surface 12 of the cup body, and a nipple accommodating area 5' for accommodating the user's nipple and its surrounding sensitive parts is formed by hollowing out the middle of the enclosed area. The nipple accommodating area 5' is connected to each sweat-venting channel 4'.

[0078] The protective layer 3' in this embodiment is adapted to the shape and size of the adhesive layer 2', and it includes three protective sheets, namely 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 are 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 are 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 are pasted on the third adhesive sheet 23'.

[0079] In this embodiment, as Figure 18As shown, within the range of the cup body 1, a non-adhesive area, a first adhesive area, and a second adhesive area may also be provided as needed. Even a third adhesive area can be further set. The adhesions of the three adhesive areas, namely the first adhesive area, the second adhesive area, and the third adhesive area, are different from each other, and the adhesive strengths of the three adhesive areas are different. At this time, the setting of the third adhesive area is based on the selection of two different adhesive requirements of the first adhesive area and the second adhesive area, and a total of up to three adhesives or up to three choices of adhesive forces are provided for the user. The areas within the range of the nipple accommodating area 5' and the areas within the range of the sweat-permeable and breathable channel 4' are set as non-adhesive areas due to the inner surface 12 of the cup body itself. The strengths of the three adhesive areas are relative, depending on which two adhesive areas are compared. However, for the adhesive area with the weakest adhesion among the three adhesive areas, its adhesion still meets the requirement of being able to be pasted on the chest multiple times. Since the 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 adjusted adaptively among the three adhesive sheets, namely the first adhesive sheet 21', the second adhesive sheet 22', and the third adhesive sheet 23', as needed. Any one of the adhesive sheets can be set as the first adhesive area, the second adhesive area, or the third adhesive area as required, but at least two adhesive areas with different strengths are provided on the three adhesive sheets, or in other words, at least two adhesions with different strengths exist 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; and so on. Of course, the settings of the first adhesive area, the second adhesive area, and the third adhesive area are not limited to this, but at least two adhesive areas or at least two adhesions are provided on the three adhesive sheets, and at most three adhesive areas or at most three adhesions are set. When the three adhesive areas, namely the first adhesive area, the second adhesive area, and the third adhesive area, are simultaneously provided within the range of the cup body 1, 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 differentially setting the first adhesive area and the second adhesive area with different adhesive strengths as needed in different regions within the cup body 1, and even further setting the third adhesive area, since the adhesive force exerted on the chest by the adhesive area with stronger adhesion is different from that exerted on the chest by the adhesive area with weaker adhesion, it is possible to provide differentially strong and weak adhesive forces for different regions of the user's chest, so that different parts of the chest are under the action of different adhesive forces, enabling the chest patch in this embodiment to provide appropriate lifting or adhesive forces with local differences to the user's chest when in use. After wearing the chest patch, it 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.

[0080] Parts associated with the aforementioned differences can be adjusted adaptively according to the need for adaptability. For those that do not require adaptive adjustment, or other parts not described, they are the same as those in the first embodiment and will not be elaborated further.

[0081] III. The third embodiment of the present utility model

[0082] For the third embodiment of the present utility model, see Figures 14 to Figure 16 The third embodiment is basically the same as the first embodiment. It also includes a cup body 1, an adhesive layer 2", and a protective layer 3". The main difference is that the adhesive layer 2" includes four adhesive patches, namely the first adhesive patch 21", the second adhesive patch 22", the third adhesive patch 23", and the fourth adhesive patch 24". A sweat ventilation channel 4" for sweating and ventilation is formed by setting an appropriate distance between the first adhesive patch 21" and the second adhesive patch 22". A sweat ventilation channel 4" for sweating and ventilation is also formed by setting an appropriate distance between the second adhesive patch 22" and the third adhesive patch 23". A sweat ventilation channel 4" for sweating and ventilation is also formed by setting an appropriate distance between the third adhesive patch 23" and the fourth adhesive patch 24". A sweat ventilation channel 4" for sweating and ventilation is also formed by setting an appropriate distance between the fourth adhesive patch 24" and the first adhesive patch 21". In this embodiment, the first adhesive patch 21" is adhered to the left side of the inner surface 12 of the cup body, the second adhesive patch 22" is adhered to the upper side of the inner surface 12 of the cup body, the third adhesive patch 23" is adhered to the right side of the inner surface 12 of the cup body, and the fourth adhesive patch 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 patch 21", the second adhesive patch 22", the third adhesive patch 23", and the fourth adhesive patch 24" are not limited to this, and they can be swapped positions according to needs and their shapes can be adjusted adaptively.

[0083] The first adhesive patch 21", the second adhesive patch 22", the third adhesive patch 2�", and the fourth adhesive patch 24" form an enclosed state in the middle of the inner surface 12 of the cup body, and a nipple accommodation area 5" for accommodating the user's nipple and its surrounding sensitive parts is formed by hollowing out the middle of the enclosed area. The nipple accommodation area 5" is connected to each sweat ventilation channel 4".

[0084] The protective layer 3” of this embodiment is adapted to the shape and size of the adhesive layer 2”. It includes four protective sheets, namely 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 are 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 are 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 are 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 are pasted on the fourth adhesive sheet 24”.

[0085] In this embodiment, as Figure 19As shown, within the range of the cup body 1, a non-sticky area, a first sticky area, and a second sticky area can also be provided as needed. Even a third sticky area can be further provided. For the description of the three sticky areas, namely the first sticky area, the second sticky area, and the third sticky area, please refer to the second embodiment and will not be elaborated here. The areas within the range of the nipple accommodation area 5" and the areas within the range of the sweat-venting and breathable channels 4" are non-sticky due to the inner surface 12 of the cup body itself and are set as non-sticky areas. 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 sticky area, the second sticky area, and the third sticky area can be adjusted adaptively among the four adhesive sheets, namely the first adhesive sheet 21", the second adhesive sheet 22", the third adhesive sheet 23", and the fourth adhesive sheet 24", as needed. Any one of the adhesive sheets can be set as the first sticky area, the second sticky area, or the third sticky area as required. For example, the first adhesive sheet 21" is set as the second sticky area, the second adhesive sheet 22" is set as the first sticky area, the third adhesive sheet 23" is set as the first sticky area or the third sticky area, and the fourth adhesive sheet 24" is set as the second sticky area or the third sticky area; or, the first adhesive sheet 21" is set as the third sticky area, the second adhesive sheet 22" is set as the second sticky area, the third adhesive sheet 23" is set as the first sticky area, and the fourth adhesive sheet 24" is set as the first sticky area; or, the first adhesive sheet 21" is set as the first sticky area, the second adhesive sheet 22 is set as the first sticky area, the third adhesive sheet 23" is set as the third sticky area or the second sticky area, and the fourth adhesive sheet 24" is set as the third sticky area or the second sticky area; and so on. Of course, the setting methods of the first sticky area, the second sticky area, and the third sticky area are not limited to this, but at least two sticky areas or at least two types of adhesiveness can be set for the four adhesive sheets, and at most three sticky areas or at most three types of adhesiveness can be set. By differentially setting the first sticky area and the second sticky area with different adhesive strengths as needed in different areas within the range of the cup body 1, and even further setting the third sticky area, since the adhesive force exerted on the chest by the sticky area with stronger adhesiveness is different from that exerted on the chest by the sticky area with weaker adhesiveness, it can provide differentially and strength-differentiated adhesive forces for different areas of the user's chest, so that different areas of the chest are under different adhesive forces, enabling the chest patch of this embodiment to provide appropriate lifting or adhesive forces with local differences to the user's chest during use. After wearing the chest patch, it 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.

[0086] Understandably, as another alternative in this embodiment, regardless of the number of manufacturing process steps, since the adhesive layer 2” includes four adhesive patches, within the range of the cup body 1, 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 as needed. The adhesiveness of the first adhesive area, the second adhesive area, the third adhesive area, and the fourth adhesive area is different, with different strengths. Each adhesive patch 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 required. However, the four adhesive patches are set with at least two adhesive areas or at least have two types of adhesiveness, and at most four adhesive areas or at most have four types of adhesiveness. That is, a total of up to four types of adhesiveness or up to four types of adhesive forces are provided for the user to choose from. The user can select and match adhesive patches with two types of adhesiveness, three types of adhesiveness, or even four types of adhesiveness on the four adhesive patches of a breast patch to adapt to and match the different adhesive force requirements of different users. When the four adhesive areas, namely the first adhesive area, the second adhesive area, the third adhesive area, and the fourth adhesive area, are simultaneously provided within the range of the cup body 1, 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 strengths of the four adhesive areas are relative, depending on which two adhesive areas are compared. However, for the weakest adhesive area among the four adhesive areas, its adhesiveness still meets the requirement of being able to be used for multiple pastes on the chest.

[0087] Regarding the part associated with the aforementioned differences, adaptability adjustments can be made according to the needs of adaptability. For those that do not require adaptability adjustments, or other parts not described, they are the same as those in the second embodiment and will not be elaborated further.

The protective layer 3D is pasted on the adhesive layer 2D. The shape of the protective layer 3D is adapted to the shape of the adhesive layer 2D. The adhesive layer 2D and the protective layer 3D are integrated and provided at the outer edge position of the outer surface of the cup body 12.

[0090] In this embodiment, the shape of the adhesive layer 2D is strip-shaped, and the shape of the protective layer 3D is strip-shaped. The outer edge of the protective layer 3D is at an appropriate distance d2 from the outer edge of the cup body 1. The size of the protective layer 3D is slightly larger than or equal to the size of the adhesive layer 2D so that the protective layer 3D can completely cover the adhesive layer 2D to protect the adhesive layer 2D. The protective layer 3D is a thin sheet-like structure with an appropriate thickness and flexibility.

[0091] The adhesive layer 2D extends along the outer edge of the inner surface of the cup body and encloses a nipple accommodating area 5D for accommodating the user's nipple and its surrounding sensitive parts. An opening is left at one end of the enclosed area to form a sweat-venting channel 4D. One end of the sweat-venting channel 4D is connected to the nipple accommodating area 5D, 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 air permeability. The adhesive layer 2D and the protective layer 3D both have appropriate widths and lengths.
