Description

Technical Field

[0001] The utility model belongs to the technical field of underwear, and more specifically relates to a breast sticker with a replaceable rubber surface. Background Art

[0002] As a personal product, breast stickers are attached to the skin when used. There is an adhesive layer on the inner side of the breast sticker, which adheres to the skin when in use. When not in use, the adhesive layer is covered with a release paper layer. If the breast sticker is not properly stored after use, such as the release paper layer is not adhered properly or the release paper layer is lost, the adhesive layer will adhere to dust and other impurities, making it difficult to clean the adhesive layer and reducing its viscosity; in addition, if the breast sticker is used multiple times, the adhesive layer will breed bacteria, which is not good for human health.

[0003] In order to solve the above problems, the prior art has a separate structure of the chest patch and the adhesive layer, that is, the chest patch and the adhesive layer are independent products. When in use, the adhesive layer is first adhered to the chest patch, and then the adhesive layer is adhered to the skin as a combination. Since the chest patch is made of elastic material and the adhesive layer is made of colloid material, the deformation degree of both is very high, which makes it difficult to adhere the adhesive layer to the chest patch smoothly during use. The adhesive layer will have wrinkles and cannot be completely adhered to the skin, resulting in poor adhesion. After being attached to the skin, it will cause discomfort and poor comfort.

DETAILED DESCRIPTION

[0033] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0034] Please also read Figure 1 and Figure 2 The replaceable adhesive chest patch provided by the utility model is now described. The replaceable adhesive chest patch includes a mold cup 1, an adhesive body 3, a fitting device 2 and a fixing structure. The mold cup 1 is made of elastic material; the mold cup 1 has an outer decorative surface 11 and an inner veneer 12 arranged oppositely; the adhesive body 3 has a cup-fitting surface 311 and a protective surface 341 arranged oppositely; the cup-fitting surface 311 is bonded to the inner veneer 12; the fitting device 2 has a positioning surface 21; the fixing structure is detachably connected to the fitting device 2, the mold cup 1 and the adhesive body 3.

[0035] The outer facing surface 11 can be attached to the positioning surface 21, and the mold cup 1 is shaped and limited by a fixed structure; or the protective surface 341 can be attached to the positioning surface 21, and the adhesive body 3 is shaped and limited by a fixed structure.

[0036] The mold cup 1 is generally a circular sheet structure, or a sheet structure similar to a circular sheet structure. After the mold cup 1 is manufactured and formed, its middle part is convex relative to the peripheral edge part. When the mold cup 1 is formed or designed, the outer surface 11 of the mold cup 1 can be formed into a curved surface and the inner surface 12 is a flat surface.

[0037] When the mold cup 1 is in use, since the mold cup 1 is made of elastic material (such as solid silicone, liquid silicone or thermoplastic elastomer), it has its own softness and deformation ability. The mold cup 1 can be deformed to make the inner surface 12 a concave surface to adapt to the human breast structure.

[0038] It should be noted that the mold cup 1 can be used independently, such as Figure 1 As shown, two mold cups 1 can also be used in combination. If two mold cups 1 are used in combination, the two mold cups 1 are connected by an intermediate connecting piece, and the intermediate connecting piece is integrally formed with the two mold cups 1. Whether one mold cup 1 is used alone or two mold cups 1 are used in combination, each mold cup 1 is shaped by the fitting device 2, and each mold cup 1 is also attached to the skin by the adhesive 3.

[0039] The cup-adhering surface 311 of the viscose 3 is sticky, and the viscose 3 is mainly made of a colloid material. Since the viscose 3 is to be adhered to the breast skin, the viscose 3 has a certain thickness, and in order to simplify the manufacturing process, the viscose 3 is generally a sheet structure, and the sheet surface is flat. The viscose 3 and the mold cup 1 are split structures, that is, the viscose 3 and the mold cup 1 are independently manufactured and packaged. When not in use, the viscose 3 and the mold cup 1 are placed independently, and before use, the cup-adhering surface 311 of the viscose 3 is adhered to the inner surface 12.

[0040] Since the mold cup 1 itself has softness and deformation ability, and the adhesive 3 also has deformation ability, if the adhesive 3 is directly bonded to the inner veneer 12, on the one hand, the inner veneer 12 is not easy to completely contact with the planar structure of the adhesive 3, and there will be many small gaps between the two. On the other hand, the mold cup 1 itself is soft. When bonding the adhesive 3, even if the mold cup 1 is placed on a flat table, human forces will inevitably be applied to the mold cup 1, causing the mold cup 1 to deform and misalign, making it difficult for the adhesive 3 to completely correspond to the mold cup 1, and the bonding operation time is long and the operation is complicated. The bonding device 2 is used to shape the mold cup 1 or the adhesive 3, and the fixed structure is used to position the mold cup 1 and the adhesive 3 to avoid deformation of the mold cup 1 or the adhesive 3.

[0041] Specifically, the bonding operation can be performed by positioning one of the mold cup 1 and the adhesive 3; for example, first align the mold cup 1 with the positioning surface 21, and attach the outer surface 11 to the positioning surface 21, and then use the fixing structure to fix the mold cup 1 on the bonding device 2, the mold cup 1 is fixed and limited, and cannot move, and the inner surface 12 can be kept as a plane or a slightly convex curved surface, and then the adhesive 3 with a planar structure is bonded to the inner surface 12. Since the mold cup 1 is made of elastic material (such as solid silicone, liquid silicone or thermoplastic elastomer), it has a certain viscosity, so it can ensure that the outer surface 11 is completely attached to the positioning surface 21.

[0042] Compared with the bonding of the unshaped surface to the plane, the bonding of the plane cup-attaching surface 311 to the shaped inner veneer 12 can ensure that the cup-attaching surface 311 is completely bonded to the inner veneer 12, there is no gap between the two, and the adhesive 3 will not have wrinkles. In addition, the fixed structure limits the mold cup 1. During the bonding operation, even if force is applied to the mold cup 1, the dual cooperation of the bonding device 2 and the fixed structure can also limit the deformation of the mold cup 1, so that the adhesive 3 can be quickly bonded to the inner veneer 12, simplifying the bonding operation, saving bonding operation time, and improving operation efficiency.

[0043] For example: first align the adhesive 3 with the positioning surface 21, attach the protective surface 341 to the positioning surface 21, and then use the fixing structure to fix the adhesive 3. The adhesive 3 is fixed and cannot move. Since the adhesive 3 is a sheet structure, it can ensure that the cup surface 311 remains flat, and then the outer decorative surface 11 of the mold cup 1 is bonded to the cup surface 311.

[0044] Since the shape of the mold cup 1 is slightly larger than that of the adhesive 3 and the mold cup 1 has a large deformation degree, in order to further facilitate user operation, it is preferred to first fix the mold cup 1 on the fitting device 2 and then adhere the adhesive 3 to the inner veneer 12.

[0045] The fixing structure can be an elastic pressing sheet. After the mold cup 1 / adhesive body 3 is attached to the positioning surface 21, the elastic pressing sheet is used to press the edge of the mold cup 1 / adhesive body 3 to achieve the purpose of fixation; the fixing structure can also be double-sided tape. After the mold cup 1 / adhesive body 3 is attached to the positioning surface 21, the double-sided tape is used to stick the edge of the mold cup 1 / adhesive body 3 to achieve the purpose of fixation; the fixing structure can also be a fixing pin 4. A positioning hole 22 is set on the bonding device 2. After the mold cup 1 / adhesive body 3 is attached to the positioning surface 21, the fixing pin 4 passes through the air hole on the mold cup 1 / adhesive body 3 and is inserted into the positioning hole 22, and the positioning is formed by plugging.

[0046] It should be noted that the laminating device 2, the mold cup 1, and the adhesive body 3 are split structures, that is, the laminating device 2, the mold cup 1, and the adhesive body 3 are independently manufactured and packaged. When not in use, the laminating device 2, the mold cup 1, and the adhesive body 3 are placed independently, and the mold cup 1 or the adhesive body 3 is attached to the positioning surface 21 before use. In addition, the laminating device 2, the adhesive body 3, and the mold cup 1 are sold at the same time. The fixing structure can be manufactured and packaged with the laminating device 2, or it can be manufactured and packaged independently.

[0047] The laminating device 2 can be made of a hard material and has a certain hardness to support the mold cup 1 or the adhesive body 3 during the laminating operation to prevent the mold cup 1 / the adhesive body 3 from being deformed.

[0048] Compared with the prior art, the breast patch with replaceable adhesive surface provided by the utility model has a fitting device 2 that can shape and limit the mold cup 1 or the adhesive body 3. Before use, the outer facing surface 11 of the mold cup 1 can be attached to the positioning surface 21, and the mold cup 1 can be shaped and limited by a fixing structure, so that the mold cup 1 cannot be dislocated and moved, so that the adhesive body 3 can be quickly and evenly adhered to the inner facing surface 12 by humans, and wrinkles on the adhesive body 3 can be avoided; alternatively, the protective surface 341 of the adhesive body 3 can be attached to the positioning surface 21, and the adhesive body 3 can be shaped and limited by a fixing structure, so that the adhesive body 3 cannot be dislocated and moved, and wrinkles will not appear, so that the mold cup 1 can be quickly and evenly adhered to the cup surface 311 by humans; when in use, the fixing structure is first removed, and then the combination of the mold cup 1 and the adhesive body 3 is removed from the positioning surface 21, and the adhesive body 3 is attached to the breast; because the adhesive body 3 has no wrinkles, it can be completely attached to the breast, ensuring the adhesive viscosity and comfort of use.

[0049] In some embodiments, the above-mentioned fixing structure can be adopted as follows Figure 1 and Figure 2 The structure shown, see Figure 1 and Figure 2 The mold cup 1 is provided with a plurality of first air holes 13; the adhesive body 3 is provided with a plurality of second air holes 35; the positioning surface 21 is provided with a plurality of positioning holes 22; the fixing structure includes at least three fixing pins 4; wherein, when the outer surface 11 is attached to the positioning surface 21, each fixing pin 4 is correspondingly inserted into the first air hole 13 and the positioning hole 22 in sequence; when the protective surface 341 is attached to the positioning surface 21, each fixing pin 4 is correspondingly inserted into the second air hole 35 and the positioning hole 22 in sequence.

[0050] In order to make the combination of the mold cup 1 and the viscose body 3 breathable and improve the comfort of use, a plurality of first breathable holes 13 are provided on the mold cup 1, and a plurality of second breathable holes 35 are provided on the viscose body 3. The positions of the plurality of first breathable holes 13 correspond to the positions of the plurality of second breathable holes 35. Both the first breathable holes 13 and the second breathable holes 35 are used for ventilation to ensure the breathable performance of the chest patch.

[0051] The fixing structure includes at least three fixing pins 4. Preferably, the fixing structure includes three fixing pins 4. The three fixing pins 4 form a triangle to determine a plane to ensure that the mold cup 1 / adhesive body 3 attached to the positioning surface 21 is fixed.

[0052] In addition, after the mold cup 1 and the adhesive body 3 are bonded, the three fixing pins 4 can be removed first, and then the combination of the mold cup 1 and the adhesive body 3 can be removed from the bonding device 2, or the combination of the mold cup 1 and the adhesive body 3 can be removed first, and then the three fixing pins 4 can be pulled out. Since the fixing pins 4 are plug-in limiters, the installation and removal methods are simple, which simplifies the manual bonding operation.

[0053] The fixing structure in this embodiment uses the fixing pin 4, cleverly utilizes the air holes of the mold cup 1 and the adhesive 3, and combines with the positioning hole 22 of the bonding device 2 to achieve limited fixation through plug-in, which simplifies the fixing method and reduces the cost.

[0054] It should be noted that the number of positioning holes 22 on the bonding device 2 can be greater than the number of first air holes 13. When positioning the mold cup 1, only three first air holes 13 are required to correspond one-to-one with the three positioning holes 22; similarly, when positioning the adhesive 3, only three second air holes 35 are required to correspond one-to-one with the three positioning holes 22.

[0055] In order to facilitate the axial correspondence between the first air hole 13 / the second air hole 35 and the positioning hole 22, please refer to Figure 1 and Figure 2 On the basis of the above embodiment, the aperture of the positioning hole 22 is smaller than the aperture of the first air hole 13 and also smaller than the aperture of the second air hole 35; the fixing pin 4 includes a first pin body 41 and a second pin body 42 connected in sequence, the first pin body 41 is a conical cylindrical structure, and the second pin body 42 is adapted to the positioning hole 22. The second pin body 42 is connected to the small diameter end of the first pin body 41.

[0056] It should be noted that the depth of the positioning hole 22 is greater than the length of the second pin body 42, so as to facilitate the adjustment of the insertion depth of the fixing pin 4. In addition, the first pin body 41 is a conical cylindrical structure, and the outer diameter of the large diameter end is slightly larger than the outer diameter of the small diameter end; by adjusting the insertion depth of the positioning pin 4, the first pin body 41 can be adapted to the first air hole 13 or the second air hole 35.

[0057] Preferably, the first vent hole 13 is a conical hole, and the small-diameter end of the conical hole faces the outer surface 11, and the large-diameter end faces the inner surface 12, and the diameter of the large-diameter end is slightly larger than the diameter of the small-diameter end. The diameter of the second vent hole 35 is slightly larger than the diameter of the first vent hole 13.

[0058] The apertures of the first air holes 13 and the second air holes 35 are larger than the apertures of the positioning holes 22. When initially positioning the mold cup 1 / adhesive body 3, it is not necessary to make three of the first air holes 13 / second air holes 35 completely axially correspond to three of the positioning holes 22. It is sufficient as long as there are overlapping parts. The fixing pin 4 is then used for insertion. The position of the mold cup 1 / adhesive body 3 is fine-tuned using the fixing pin 4, which further simplifies the bonding operation.

[0059] Since the mold cup 1 and the adhesive body 3 are made separately and packaged independently, in order to ensure that the plurality of first air holes 13 correspond to the plurality of second air holes 35 after the mold cup 1 and the adhesive body 3 are bonded, based on the above embodiment, the height of the first pin body 41 is greater than the thickness of the mold cup 1 and the thickness of the adhesive body 3. Figure 3 shown.

[0060] After the outer facing surface 11 of the mold cup 1 is attached to the positioning surface 21, the second pin body 42 is passed through the first air hole 13 and the positioning hole 22 in sequence. Since the height of the first pin body 41 is greater than the thickness of the mold cup 1, the first pin body 41 will protrude from the mold cup 1. When the cup-attaching surface 311 of the adhesive body 3 is attached to the inner cladding surface 12, the second air hole 35 will also pass through the first pin body 41. Similarly, if the adhesive body 3 is attached first, the protective surface 341 is attached to the positioning surface 21, and the second pin body 42 is passed through the second air hole 35 and the positioning hole 22 in sequence, the first pin body 41 will protrude from the adhesive body 3. When the inner cladding surface 12 of the mold cup 1 is attached to the adhesive body 3 and the cup-attaching surface 311, the second air hole 35 will also pass through the first pin body 41. By fixing the pin 4, it can also be ensured that the first air hole 13 and the second air hole 35 are axially corresponding.

[0061] In some embodiments, the laminating device 2 may be used as follows: Figure 3 The structure shown, see Figure 3 The fitting device 2 has a volume cavity, the cavity structure of the volume cavity is adapted to the thickness of the outer shape of the mold cup 1, and the cavity wall of the volume cavity is the positioning surface 21.

[0062] The laminating device 2 can be made of a hard material with a certain hardness. The laminating device 2 can be regarded as a flat plate, one side of which is provided with a downwardly concave volume cavity, which is used to shape and limit the mold cup 1 / adhesive body 3, especially the mold cup 1. Since the cavity structure of the volume cavity is compatible with the outer structure of the mold cup 1, after the mold cup 1 is manually placed in the volume cavity, the volume cavity limits the state of the mold cup 1, and the inner veneer 12 can be kept flat, so as to facilitate the bonding of the planar structure of the adhesive body 3 and the inner veneer 12.

[0063] Specifically, the mold cup 1 is a structure of unequal thickness. Preferably, in order to adapt to the shape of the breast, the thickness of the mold cup 1 decreases from the center point to the peripheral edge, that is, the thickness at the center point of the mold cup 1 is the largest, and the thickness at the peripheral edge is the smallest.

[0064] After the mold cup 1 is manufactured and formed, the middle part thereof is convex relative to the peripheral edge part, and during the molding or designing of the mold cup 1, the outer facing surface 11 can be formed into a curved surface, and the inner veneer 12 can be formed into a flat shape. The mold cup 1 is made of elastic material (such as solid silicone, liquid silicone or thermoplastic elastomer), so the mold cup 1 itself has softness and deformation ability. When in use, it can be deformed so that the inner veneer 12 is a concave curved surface to adapt to the shape of the breast.

[0065] Designing the mold cup 1 to have an unequal thickness structure can reduce the deformation of the outer facing surface 11. Moreover, since the cavity structure of the volume cavity is adapted to the thickness of the outer shape of the mold cup 1, after the mold cup 1 is limited in the volume cavity, the inner veneer 12 can be flat, and the outer facing surface 11 can still be a curved surface, so as to facilitate the next step of bonding the adhesive 3.

[0066] In addition, since the cavity structure of the volume cavity is adapted to the thickness of the outer shape of the mold cup 1, that is, the heights at various points of the volume cavity are also not equal, the cavity wall of the volume cavity, i.e., the positioning surface 21, is an arc surface. The arc surface structure has more limiting directions than the plane structure. When bonding the adhesive 3, the mold cup 1 can be limited in multiple directions.

[0067] Since the fitting device 2 only has a volume cavity, its structure is simple, easy to manufacture, and has a low manufacturing cost. Compared with the method of manually brushing glue on the mold cup 1 or hot-melt forming the adhesive body 3, the replaceable adhesive breast patch provided in this embodiment can be reused multiple times, has a lower use cost, and when not in use, the adhesive body 3 is independently packaged, will not breed bacteria, and is more beneficial to human health.

[0068] In addition to limiting the mold cup 1, the volume cavity can also limit the viscose 3. Since the viscose 3 is a planar equal-thickness structure, after the viscose 3 is bonded to the volume cavity, a curved equal-thickness structure will be formed, and the curved surface shape of the cup surface 311 is compatible with the curved surface shape of the positioning surface 21, that is, it can be compatible with the curved surface shape of the outer decorative surface 11, thereby facilitating the bonding of the mold cup 1 to the viscose 3.

[0069] In some embodiments, the above-mentioned replaceable rubber chest patch can also be used as follows Figure 1 and Figure 2 The structure shown, see Figure 1 and Figure 2 The replaceable adhesive chest patch also includes a pressure roller 5; after the cup surface 311 is adhered to the inner surface 12, the pressure roller 5 is used to roll the adhesive 3; or after the inner surface 12 is adhered to the cup surface 311, the pressure roller 5 is used to roll the mold cup 1.

[0070] After the adhesive 3 is manually bonded to the mold cup 1 , a pressure roller 5 can be manually used to roll on the protective surface 341 / the outer surface 11 to squeeze out small bubbles between the adhesive 3 and the mold cup 1 , thereby further improving the bonding degree between the adhesive 3 and the mold cup 1 .

[0071] The pressure roller 5 can be packaged together with the laminating device 2 or separately. The pressure roller 5 is sold together with the laminating device 2, the adhesive 3 and the mold cup 1.

[0072] In some embodiments, the viscose 3 may be formed as follows: Figure 4 The structure shown, see Figure 4The adhesive body 3 includes an adhesive body and a first release paper layer 34. One side of the adhesive body is a cup-adhering surface 311, and the other side is a skin-adhering surface 321; one side of the first release paper layer 34 is adhered to the skin-adhering surface 321, and the other side is a protective surface 341.

[0073] Both the cup-adhering surface 311 and the skin-adhering surface 321 are sticky. The cup-adhering surface 311 is used to be attached to the inner surface 12, and the skin-adhering surface 321 is used to be attached to the breast. The first release paper layer 34 itself is not sticky, but the first release paper layer 34 itself has hardness and can maintain a flat state. The first release paper layer 34 covers the skin-adhering surface 321 to protect the skin-adhering surface 321 and prevent the skin-adhering surface 321 from being attached to impurities before being attached to the skin, thereby affecting the stickiness and comfort of use.

[0074] Before the adhesive body 3 is attached, the first release paper layer 34 is attached to the skin-contacting surface 321. The hardness of the first release paper layer 34 can keep the adhesive body 3 in a flat state as a whole, thereby further ensuring that the adhesive body 3 and the mold cup 1 are adhered to each other without gaps. After the combination of the adhesive body 3 and the mold cup 1 is removed from the laminating device 2, the first release paper layer 34 is torn off to expose the skin-contacting surface 321.

[0075] Since the adhesive body 3 and the mold cup 1 are independently manufactured and packaged, when not in use, the adhesive body 3 and the mold cup 1 are placed independently. In order to ensure the viscosity of the cup surface 311, a second release paper layer can be adhered to the cup surface 311.

[0076] In some embodiments, the adhesive body may be Figure 4 The structure shown, see Figure 4 The adhesive body includes a first adhesive layer 31 , a middle elastic layer 33 and a second adhesive layer 32 which are bonded in sequence; the outer surface of the first adhesive layer 31 is a cup-adhering surface 311 ; the outer surface of the second adhesive layer 32 is a skin-adhering surface 321 .

[0077] The first adhesive layer 31 is used to adhere to the inner veneer 12, and the second adhesive layer 32 is used to adhere to the skin. Preferably, the first adhesive layer 31 is a pressure-sensitive adhesive layer, which has good adhesion and peeling strength, is suitable for bonding to the mold cup 1, and is not easy to fall off or move after bonding. The silicone gel layer is made of silicone gel, has a low peeling strength, and will not cause pain to the user when it is torn off. A number of small holes can be set on the silicone gel layer to improve the moisture permeability and air permeability, making the application more comfortable.

[0078] The middle elastic layer 33 is used as a base material for coating the first adhesive layer 31 and the second adhesive layer 32, making it easier to shape the adhesive body 3. The middle elastic layer 33, as a base material, can also provide support for the first adhesive layer 31 and the second adhesive layer 32, so that the adhesive body 3 can be torn off the mold cup 1 as a whole, so as to ensure that the mold cup 1 and the adhesive body 3 can be reused.

[0079] It should be noted that the middle elastic layer 33 needs to have waterproof and breathable properties and should not cause any harm to human skin.

[0080] Preferably, the middle elastic layer 33 is made of cloth, or made of thin film materials such as silicone film, PU film, etc. The middle elastic layer 33 itself is elastic, and the layered structure formed has contraction and expansion properties, so that the entire viscose body 3 has contraction and expansion properties.

[0081] Specifically, before adhering the viscose 3 to the mold cup 1, the viscose 3 is first leveled. Since the middle elastic layer 33 is expandable, when the viscose 3 is manually leveled, the middle elastic layer 33 expands, which can also expand the first adhesive layer 31, so that the cup-attaching surface 311 remains completely in contact with the inner veneer 12; after the viscose 3 is adhered, the combination of the mold cup 1 and the viscose 3 is removed from the positioning surface 21, and the mold cup 1 is no longer limited and the structure of the use state is restored. At this time, the mold cup 1 also deforms the viscose 3. Since the middle elastic layer 33 is shrinkable and expandable, after changing from a flat surface to a curved surface, the part coated with the first adhesive layer 31 can expand, and the part coated with the second adhesive layer 32 can shrink, thereby expanding the first adhesive layer 31 and shrinking the second adhesive layer 32, so that the viscose 3 adapts to the concave curved surface structure of the inner veneer 12 when in use, and the skin-contacting surface 321 has no wrinkles.

[0082] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
