[0035] In the following description, reference is made to the accompanying drawings which form a part thereof, and in which various embodiments are shown by way of illustration. It should be understood that other embodiments are contemplated and may be made without departing from the scope or spirit of the present disclosure. Therefore, the following detailed description should not be construed in a limiting sense.

[0036] In the following disclosure, the following definitions apply.

[0037] As used herein, all numbers should be considered to be modified by the term “about.” As used herein, “a,” “an,” “the,” “at least one,” and “one or more” are used interchangeably.

[0038] As used herein as a modifier of a property or attribute, unless otherwise specifically defined, the term "substantially" means that the property or attribute would be readily recognized by a skilled artisan but does not require absolute precision or a perfect match (e.g., within + / - 20% for a quantifiable property).

[0039] Unless specifically defined otherwise, the term "substantially" means a high degree of approximation (eg, within + / - 10% for a quantifiable property), but likewise does not require absolute precision or a perfect match.

[0040] Unless specifically defined otherwise, the term "about" means a close approximation (eg, within + / - 5% for a quantifiable property), but again does not require absolute precision or a perfect match.

[0041] As used herein, the terms "first" and "second" are used as identifiers. Therefore, such terms should not be interpreted as limiting the present disclosure. The terms "first" and "second" are interchangeable in embodiments of the present disclosure when used in conjunction with features or elements.

[0042] As used herein, “at least one of A and B” should be understood to mean “only A, only B, or both A and B”.

[0043] As used herein, the recitation of numerical ranges by endpoints includes all numbers subsumed within that range as well as the endpoints (eg, 1 to 5 includes 1, 1.5, 2, 2.75, 3, 3.80, 4, 5, etc.).

[0044] As used herein, the term "adhesive" generally refers to a polymer composition that can be used to adhere two adherends together. Examples of adhesives may include curable adhesives, heat activated adhesives, pressure sensitive adhesives, or combinations thereof.

[0045] As used herein, the term "layer" generally refers to a planar sheet of material, film, fabric, or covering formed using only one formulated composition or single substance.

[0046] According to aspects of the present disclosure, an article includes at least one substrate. The article also includes at least one adhesive member, the at least one adhesive member including a first major surface and a second major surface opposite to the first major surface. The first major surface is connected to the at least one substrate. The at least one adhesive member also includes an adhesive layer, the adhesive layer forming the second major surface of the at least one adhesive member. The adhesive layer includes an adhesive, the adhesive being configured to bond the at least one adhesive member to an outer surface. The at least one adhesive member also includes at least one slit, the at least one slit extending from the first major surface to the second major surface through the at least one adhesive member. The article also includes at least one tab, the at least one tab being connected to at least the adhesive layer of the at least one adhesive member and extending from the at least one adhesive member. The at least one tab is configured to receive a pulling force from a user. When a pulling force is applied to the at least one tab, the at least one adhesive member is at least partially separated adjacent to the at least one slit and peeled off from each of the at least one substrate and the outer surface.

[0047] In the article of the present disclosure, the at least one tab is connected to at least the adhesive layer of the at least one adhesive member. Thus, pulling the at least one tab may result in exerting a force on the at least one adhesive layer. The at least one tab may be accessible to a user of the article. Pulling the at least one tab may effect at least partial separation of the at least one adhesive member adjacent to the at least one slit, thereby peeling the at least one adhesive member from each of the at least one substrate and the outer surface. Thus, the user may be able to conveniently remove the article from the outer surface by pulling the at least one tab.

[0048] At least one adhesive member may include a bulk material that allows the at least one adhesive member to be pulled and at least partially separated adjacent to the at least one slit. In addition, the at least one slit may achieve a reduction in the force required to peel the at least one adhesive member (e.g., by necking) compared to conventional adhesive members that include a continuous piece of adhesive.

[0049] In addition, compared to conventional adhesive members including discontinuous slit patterns, at least one slit of the present disclosure may be continuous and may extend from at least one tab along the first major surface or the second major surface until the end of at least one adhesive member. In addition, conventional adhesive members (having perforations or holes) may be pulled as a single continuous body. However, at least one slit of the present disclosure may allow at least one adhesive member to be formed as a single elongated continuous block of material with a narrow cross-sectional area. When a pulling force is applied to at least one tab, this may achieve a smaller necked cross-sectional area for at least one adhesive member, thereby reducing the magnitude of the pulling force required to peel at least one adhesive member. Therefore, the effect of peeling at least one adhesive member on both at least one substrate and the outer surface may be minimized.

[0050] In some examples, at least one adhesive member includes a plurality of slits that are substantially parallel to each other. This can divide the necking region of at least one adhesive member into a plurality of smaller necking regions with reduced cross-sectional areas, whereas conventional adhesive members include a single necking region, and the entire cross-sectional area of ​​at least one adhesive member orthogonal to the direction of the pulling force is activated or stretched at the same time. Therefore, at least one adhesive member of the present disclosure having a plurality of slits can further reduce the magnitude of the pulling force required to peel off at least one adhesive member.

[0051] In addition, when a pulling force is applied to at least one tab, a plurality of smaller necked regions with reduced cross-sectional areas created by the plurality of slits in at least one adhesive member may be activated or stretched individually, sequentially, or in parallel. In addition, at least one tab may include one or more tabs attached to each of the plurality of necked regions to assist in removing the at least one adhesive member. In some embodiments, the plurality of smaller necked regions with reduced cross-sectional areas may require a lower pulling force to remove the at least one adhesive member from each of a substrate and an outer surface.

[0052] It should be noted that the plurality of slits of the at least one adhesive member may not significantly reduce the adhesion of the at least one adhesive member to an external surface (such as the skin of a user), but facilitate the peeling of the at least one adhesive member from each of the at least one substrate and the external surface without any significant damage or residue. In addition, in the case where the external surface is the skin of the user, the at least one slit may allow moisture to be transmitted through the at least one adhesive member, thereby improving the permeability and breathability of the at least one adhesive member.

[0053] Now referring to the accompanying drawings, Figure 1A is a schematic top perspective view of an article 100. The article 100 is attached to an outer surface 102. Figure 1B is a schematic bottom perspective view of article 100 . Figure 2 is a schematic cross-sectional perspective view of article 100. Referring now to Figure 1A to Figure 2 , the article 100 includes at least one substrate 104. The article 100 also includes at least one adhesive member 110 (shown in Figure 1B and Figure 2 ). The article 100 is attached to the outer surface 102 via an adhesive member 110. The term "at least one substrate 104" is hereinafter interchangeably referred to as "substrate 104". The term "at least one adhesive member 110" is hereinafter interchangeably referred to as "adhesive member 110".

[0054] In some examples, at least one substrate 104 includes a main portion 108 coupled to at least one adhesive member 110. Figure 1A to Figure 2 In the illustrated example, the main portion 108 is rectangular (ie, polygonal). In some other examples, the main portion 108 may be circular, oval, or elliptical. It should be understood that the main portion 108 may be any shape and geometry, including irregular shapes, based on application requirements.

[0055] In some examples, the base 104 further includes one or more side portions 105 extending from the main portion 108. In some examples, the one or more side portions 105 at least partially surround the at least one adhesive member 110. Figure 1A to Figure 2In the illustrated example, the one or more side portions 105 include a plurality of side portions 105 spaced apart from each other. In some examples, the plurality of side portions 105 may prevent external agents such as dust from reaching the adhesive member 110 .

[0056] In some examples, at least one substrate 104 includes at least one cutout 118. Specifically, at least one cutout 118 includes a plurality of cutouts 118 separating the plurality of side portions 105 from each other. In some examples, each cutout 118 from the plurality of cutouts 118 is disposed between a corresponding adjacent pair of side portions 105 from the plurality of side portions 105.

[0057] In some examples, substrate 104 can be a backing for adhesive member 110. In some examples, substrate 104 can be part of a medical diagnostic device, and outer surface 102 can be the skin of a user. For example, a medical diagnostic device can be attached to the skin of a user via adhesive member 110. In some examples, a medical diagnostic device can include one or more sensors mounted thereon.

[0058] like Figure 1B 1C , at least one adhesive member 110 includes a first major surface 112 and a second major surface 114 opposite to the first major surface 112. The first major surface 112 is connected to at least one substrate 104. At least one adhesive member 110 also includes an adhesive layer 116 that forms the second major surface 114 of at least one adhesive member 110.

[0059] Adhesive layer 116 includes an adhesive configured to bond at least one adhesive member 110 to outer surface 102 (shown in FIG. Figure 1A In some examples, the adhesive is a pressure sensitive adhesive or a stretch release adhesive. In some examples, the article 100 also includes a release liner 106 (shown in FIG. 1 ) releasably attached to the adhesive layer 116. Figure 2 In some examples, the release liner 106 is disposed between the adhesive layer 116 and the outer surface 102 (shown in Figure 1A The release liner 106 is removed before bonding. Figure 1A and Figure 1B Not shown.

[0060] At least one adhesive member 110 also includes at least one slit 120 extending through at least one adhesive member 110 from first major surface 112 to second major surface 114. Thus, at least one slit 120 is a through slit. In some examples, at least one slit 120 may also extend along first major surface 112 or second major surface 114. In some examples, at least one slit 120 may be arranged in a predetermined pattern along first major surface 112 and second major surface 114. The term "at least one slit 120" is hereinafter interchangeably referred to as "slit 120".

[0061] In some examples, the slits 120 can be produced by cutting through the adhesive member 110 by a variety of known methods. Specifically, the slits 120 can be produced by cutting through a continuous area of ​​the adhesive member 110 in a predetermined pattern, so that the predetermined pattern can impart specific mechanical properties to the adhesive member 110. Such mechanical properties can also be different in different directions. Alternatively, the adhesive member 110 can be directly dispensed from the robotic platform in a predetermined pattern (such as in the form of elongated portions). It should be understood that based on the application requirements, the adhesive member 110 can be formed in different shapes / geometries, and the slits 120 can be formed in different shapes / patterns.

[0062] like Figure 1A and Figure 1B As shown, the article 100 also includes at least one tab 130 connected to at least the adhesive layer 116 of the at least one adhesive member 110 and extending from the at least one adhesive member 110. In some examples, the at least one cutout 118 is configured to at least partially receive the at least one tab 130 through the at least one cutout. In some examples, the at least one tab 130 may be made of a material different from the material of the adhesive member 110. In some other examples, the at least one tab 130 may be made of the same material as the material of the adhesive member 110. The term "at least one tab 130" is interchangeably referred to as "tab 130" hereinafter.

[0063] In some examples, at least one tab 130 and at least one adhesive member 110 have the same layered construction. In other words, at least one tab 130 and at least one adhesive member 110 include the same layer (i.e., similar composition) having the same corresponding thickness. In some examples, at least one tab 130 includes an adhesive layer 131. In some examples, adhesive layer 131 includes a pressure-sensitive adhesive or a stretch-release adhesive. In some examples, adhesive layer 131 may include an adhesive similar to the adhesive of adhesive layer 116. Alternatively, in some other examples, at least one tab 130 may be non-adhesive.

[0064] At least one tab 130 is configured to receive a pulling force F from a user. When the pulling force F is applied to at least one tab 130, at least one adhesive member 110 is at least partially separated adjacent to at least one slit 120 and peeled off from each of at least one substrate 104 and outer surface 102. Thus, the user may be able to peel the substrate 104 from the outer surface 102 by pulling the tab 130.

[0065] In some examples, at least one tab 130 can be adhesive. For example, at least one tab 130 can be an extension of at least one adhesive member 110. In such cases, at least one tab 130 can be grasped and pulled by a user to stretch at least one adhesive member 110 to peel substrate 104 from outer surface 102. In some examples, at least one tab 130 can include those described in U.S. Pat. No. 9,587,146 (Sherman et al.) and U.S. Pat. No. 9,228,117 (Sherman et al.), the disclosures of which are incorporated by reference in their entireties.

[0066] Figure 3 is a schematic bottom view of the article 100. In some examples, the at least one adhesive member 110 further includes a first longitudinal edge 136 extending along the longitudinal axis L, a second longitudinal edge 138 on the opposite side of the first longitudinal edge 136 and extending at least partially along the longitudinal axis L, a first transverse edge 142 extending between the first longitudinal edge 136 and the second longitudinal edge 138 along a transverse axis T orthogonal to the longitudinal axis L, and a second transverse edge 144 on the opposite side of the first transverse edge 142 and extending between the first longitudinal edge 136 and the second longitudinal edge 138 along the transverse axis T.

[0067] In some examples, the at least one slit 120 includes a plurality of slits 120 that are spaced apart from each other relative to the transverse axis T and extend at least partially along the longitudinal axis L. In some examples, the plurality of slits 120 includes a set of first slits 122 and a set of second slits 124 that alternate with the set of first slits 122. In some examples, each first slit 122 from the set of first slits 122 extends partially from the first transverse edge 142 toward the second transverse edge 144, such that each first slit 122 is spaced apart from the second transverse edge 144. In some examples, each second slit 124 from the set of second slits 124 extends partially from the second transverse edge 144 toward the first transverse edge 142, such that each second slit 124 is spaced apart from the first transverse edge 142. It should be understood that the set of first slits 122 and the set of second slits 124 may include any number of first slits 122 and second slits 124, respectively.

[0068] In some examples, at least one adhesive member 110 includes a plurality of elongated portions 146 extending at least partially along the longitudinal axis L between the first lateral edge 142 and the second lateral edge 144. In some examples, adjacent elongated portions 146 from the plurality of elongated portions 146 are at least partially separated from each other by a corresponding first slit 122 from the set of first slits 122 or a corresponding second slit 124 from the set of second slits 124. In some examples, adjacent elongated portions 146 are connected to each other at the first lateral edge 142 or the second lateral edge 144, such that the plurality of elongated portions 146 together form a serpentine pattern 140. Thus, the set of first slits 122 and the set of second slits 124 can allow the at least one adhesive member 110 to be formed as a single elongated, continuous block of material having a narrow cross-sectional area.

[0069] In some examples, the plurality of elongated portions 146 include an end elongated portion 148 disposed at the second longitudinal edge 138. In some examples, the set of first slits 122 includes an end first slit 126 disposed proximate the second longitudinal edge 138 and at least partially separating the end elongated portion 148 from adjacent elongated portions 146.

[0070] In some examples, the end elongated portion 148 includes a first elongated portion 150 connected to the adjacent elongated portion 146 and extending along the longitudinal axis L, a second elongated portion 152 extending from the first elongated portion 150 and inclined obliquely relative to the first elongated portion, and a third elongated portion 154 extending from the second elongated portion 152 along the longitudinal axis L.

[0071] In some examples, the end first slit 126 includes a first slit portion 156 extending from the first lateral edge 142 along the longitudinal axis L, a second slit portion 158 extending from the first slit portion 156 and inclined obliquely relative to the first slit portion, and a third slit portion 160 extending from the second slit portion 158 partially along the longitudinal axis L toward the second lateral edge 144.

[0072] In some examples, at least one tab 130 is connected to the end elongated portion 148 and is disposed adjacent to the end first slit 126. Specifically, at least one tab 130 extends from the third elongated portion 154. In some examples, at least one tab 130 includes a curved portion 132 extending from at least one adhesive member 110, and a disc-shaped portion 134 connected to the curved portion 132 at a distal side of the at least one adhesive member 110.

[0073] The tab 130 is configured to receive a pulling force F from a user. When the pulling force F is applied on the tab 130 by the user, the adhesive member 110 is at least partially separated adjacent to the plurality of slits 120 and peeled from each of the substrate 104 and the outer surface 102 (shown in FIG. 1 ), for example, by necking. In other words, when the pulling force F is applied, the serpentine pattern 140 of the at least one adhesive member 110 spreads along the plurality of slits 120 (e.g., like a ribbon) and peels from each of the substrate 104 and the outer surface 102 (shown in FIG. 1 ). Since the at least one adhesive member 110 of the present disclosure is formed as a single elongated continuous block of material having a narrow cross-sectional area orthogonal to the direction of the pulling force F, the magnitude of the pulling force F required to peel the at least one adhesive member 110 can be reduced compared to conventional adhesive members (having perforations or holes) that are pulled as a single continuous body.

[0074] In some examples, when a pulling force F is applied by a user to tab 130, adhesive member 110 may slide out of at least one cutout 118, thereby peeling substrate 104 from outer surface 102 (shown in FIG. 1 ). Alternatively, when a pulling force F is applied by a user to tab 130, adhesive member 110 may slide out under one or more side portions 105, thereby peeling substrate 104 from outer surface 102 (shown in FIG. 1 ).

[0075] In some examples, adhesive member 110 may include a bulk material that allows adhesive member 110 and adhesive layer 116 to receive a pulling force through tab 130 without breaking. In other words, adhesive member 110 is strong enough to withstand the pulling force applied to adhesive member 110. For example, a suitable material that provides structural strength to adhesive member 110 may be selected for adhesive member 110 based on chemical properties or inherent material properties. It should be understood that any suitable material that provides sufficient strength to adhesive member 110 may be used for adhesive member 110.

[0076] Figure 4 is a schematic bottom view of at least one adhesive member 110. Figure 4 In the illustrated example, each of the end first slit 126 and the end elongated portion 148 extends along the longitudinal axis L. In some examples, at least one tab 130 includes a linear portion 128 extending from at least one adhesive member 110, and a disc-shaped portion 134 connected to the linear portion 128 at a distal side of the at least one adhesive member 110.

[0077] Figure 5A FIG. 1 is a schematic bottom view of a portion of adhesive member 110 and tab 130. Figure 5A In the illustrated example, a single slit 120 is shown for illustration purposes. Figure 5B 1 is a schematic bottom view of the portion of adhesive member 110 and tab 130, wherein a pulling force F is applied to tab 130. In some examples, slit 120 extends along a slit axis S, and the pulling force F is applied along a pulling direction P. Figure 5B In the illustrated example, the pulling direction P is substantially parallel to the slit axis S of the slit 120 .

[0078] Reference now Figure 5A and Figure 5B In some examples, adhesive member 110 is removed from substrate 104 (shown in FIG. 1 ) by necking in response to application of a pulling force F on tab 130. Figures 1A to 3 ) and the outer surface 102 (shown in Figure 1A Specifically, the adhesive member 110 is necked down in response to the pulling force F applied on the tab 130 before being completely peeled off to form a necked area N, as indicated by the peeled area R. Therefore, the adhesive member 110 may be first stretched to be narrowed before the adhesive member 110 is completely peeled off.

[0079] The adhesive member 110 of the present disclosure includes at least one slit 120 extending from at least one tab 130 to or near an end 111 of the at least one adhesive member 110. In addition, compared to conventional adhesive members that include a single necked region and in which the entire cross-sectional area of ​​the adhesive member orthogonal to the direction of the pulling force is activated or stretched at the same time, the at least one slit 120 enables the at least one adhesive member 110 to be peeled off by forming a plurality of smaller necked regions N. Therefore, the magnitude of the pulling force F required to peel off the adhesive member 110 can be significantly lower than in the case where the adhesive member includes a block material that is continuous or has discontinuous slits, thereby causing less damage to the bonded surface.

[0080] In some examples, the amount of pulling force F required to peel adhesive member 110 may depend on the width of adhesive member 110. Therefore, reducing the width of adhesive member 110 may reduce the pulling force F required to peel adhesive member 110. In addition, the amount of pulling force F required to peel adhesive member 110 may increase as the width of adhesive member 110 increases. Therefore, if a wider adhesive member 110 can be provided, multiple slits 120 can be used to allow multiple necked areas to be created, thereby reducing the amount of pulling force F required to peel adhesive member 110.

[0081] Fig. 6A is a schematic bottom view of an adhesive member 110 and a tab 130 according to another embodiment of the present disclosure. Figure 6B1 is a schematic bottom view of a portion of the adhesive member 110 and the tab 130, wherein a pulling force F is applied to the tab 130. Specifically, a pulling direction P of the pulling force F is inclined toward the slit axis S of the slit 120.

[0082] Reference now Fig. 6A and Figure 6B , when the pulling direction P of the pulling force F is inclined toward the slit axis S of the slit 120, the magnitude of the pulling force F required to peel off the adhesive member 110 is still lower than when the adhesive member 110 includes a continuous piece of adhesive. In some examples, the adhesive member 110 is removed from the substrate 104 (shown in FIG. 1 ) by necking in response to the application of the pulling force F on the tab 130. Figures 1A to 3 ) and the outer surface 102 (shown in Figure 1A Specifically, adhesive member 110 necks downward in response to application of pulling force F on tab 130 before being completely peeled off to form necked region N, as indicated by peeled region R. The reduction in the magnitude of pulling force F can also be attributed to the presence of slit 120, resulting in less damage to the bonded surfaces.

[0083] Figure 7 FIG. 1 is a schematic bottom view of a portion of an adhesive member 110 according to another embodiment of the present disclosure. Figure 7 In the illustrated example, a single slit 120 is shown for illustrative purposes. In addition, the pulling direction P of the pulling force F is inclined toward the slit axis S of the slit 120 .

[0084] In some examples, adhesive member 110 is rolled from substrate 104 (shown in FIG. Figures 1A to 3 ) and the outer surface 102 (shown in Figure 1A In some examples, when the pulling direction P of the pulling force F is not aligned with the slit axis S of the slit 120, it is possible that the adhesive member 110 is rolled on itself and peeled off from the substrate 104 (shown in FIG. 1 ) before the adhesive member 110 is subjected to sufficient force to cause necking. Figures 1A to 3 ) and the outer surface 102 (shown in Figure 1A This peeling mechanism may depend on the bond strength to the bonded surface and the function of the elastic modulus of the adhesive member 110. The magnitude of the pulling force F required to peel the adhesive member 110 having the slits 120 is still lower than the case where the adhesive member 110 includes a continuous piece of adhesive.

[0087] In some examples, core layer 162 includes foam. However, it should be understood that any other suitable material may be selected for core layer 162. In some examples, core layer 162 may include a film layer. In such cases, the film layer may match the necking behavior of adhesive member 110, or may withstand the force in pulling direction P (shown in FIG. FIG. 5A to FIG. 7 ), while not restricting the necking behavior of the adhesive member 110.

[0088] In some examples, core layer 162 can increase the structural strength of adhesive member 110, allowing adhesive member 110 to withstand the pulling force applied to adhesive member 110 so as to separate adhesive member 110 from substrate 104 (shown in FIG.

Reference will be made to Figures 1A to 17 The method 700 is described with reference to the articles 100 , 400 , 500 , 600 .

[0129] Reference now Figures 1A to 18 At step 702, method 700 includes adhesively bonding at least one adhesive member 110, 210, 310, 410, 510, 610 to outer surface 102. Referring now to Figures 1A to 18 At step 704, method 700 also includes applying a pulling force F to at least one tab 130, 230, 330, 430, 530, 630 to cause at least a partial separation of at least one adhesive member 110, 210, 310, 410, 510, 610 adjacent to at least one slit 120, 220, 320, 420, 520, thereby peeling at least one adhesive member 110, 210, 310, 410, 510, 610 from each of at least one substrate 104, 404, 504, 604 and the outer surface 102.

[0130] In some examples, at least one adhesive member 110 , 210 , 310 , 410 , 510 , 610 is peeled from each of at least one substrate 104 , 404 , 504 , 604 and outer surface 102 by at least one of necking and rolling.

[0131] In some examples, at least one adhesive member 610 includes a plurality of adhesive members 610 connected to each other. In some examples, applying a pulling force F to at least one tab 630 connected to one of the plurality of adhesive members 610 causes the plurality of adhesive members 610 to be successively peeled off from each of the at least one substrate 604 and the outer surface 102.

[0132] In some examples, at least one slit 420, 520 has a spiral shape, such that at least one adhesive member 410, 510 includes a spiral coil 406, 506 corresponding to the spiral shape of at least one slit 420, 520. In some examples, when the pulling force F is applied, the spiral coil 406, 506 of the at least one adhesive member 410, 510 unwinds along the spiral shape of the at least one slit 420, 520.

[0133] In some examples, at least one slit 120 has a plurality of slits 120 spaced apart from each other and forming a serpentine pattern 140 of at least one adhesive member 110. In some examples, when a pulling force F is applied, serpentine pattern 140 of at least one adhesive member 110 expands along the plurality of slits 120.

[0134] In some examples, method 700 also includes removing release liner 106 from at least one adhesive member 110 , 210 , 310 , 410 , 510 , 610 prior to bonding at least one adhesive member 110 , 210 , 310 , 410 , 510 , 610 to outer surface 102 .

[0135] In the articles 100, 400, 500, 600 of the present disclosure, at least one tab 130, 230, 330, 430, 530, 630 is connected to at least the adhesive layer 116, 216, 316, 416, 516, 616 of at least one adhesive member 110, 210, 310, 410, 510, 610. The at least one tab 130, 230, 330, 430, 530, 630 may be accessible to a user of the article 100, 400, 500, 600. Pulling the at least one tab 130, 230, 330, 430, 530, 630 may cause at least a portion of the at least one adhesive member 110, 210, 310, 410, 510, 610 adjacent to the at least one slit 120, 220, 320, 420, 520 to separate, thereby peeling the at least one adhesive member 110, 210, 310, 410, 510, 610 from each of the at least one substrate 104, 404, 504, 604 and the outer surface 102. Thus, the user may be able to easily remove the article 100, 400, 500, 600 from the outer surface 102.

[0136] At least one adhesive member 110, 210, 310, 410, 510, 610 may include a bulk material that allows at least one adhesive member 110, 210, 310, 410, 510, 610 to at least partially separate adjacent at least one slit 120, 220, 320, 420, 520 when at least one tab 130, 230, 330, 430, 530, 630 is pulled. In addition, at least one slit 120, 220, 320, 420, 520 may achieve a reduction in the force required to peel off at least one adhesive member 110, 210, 310, 410, 510, 610 (e.g., by necking) compared to conventional adhesive members that include a continuous piece of adhesive.

[0137] The at least one slit 120, 220, 320, 420, 520 of the present disclosure may be continuous and may extend from the at least one tab 130, 230, 330, 430, 530, 630 along the first major surface 112 or the second major surface 114 to the end of the at least one adhesive member 110, 210, 310, 410, 510, 610. Thus, the at least one slit 120, 220, 320, 420, 520 may allow the at least one adhesive member 110, 210, 310, 410, 510, 610 to be formed as a single elongated continuous block of material having a narrow cross-sectional area. This can achieve a smaller necked cross-sectional area for at least one adhesive member 110, 210, 310, 410, 510, 610 when a pulling force F is applied to at least one tab 130, 230, 330, 430, 530, 630, thereby reducing the magnitude of the pulling force F required to peel off at least one adhesive member 110, 210, 310, 410, 510, 610. Thus, the effect of peeling off at least one adhesive member 110, 210, 310, 410, 510, 610 on both at least one substrate 104, 404, 504, 604 and outer surface 102 can be minimized.

[0138] In some examples, at least one slit 120, 220, 320, 420, 520 includes a plurality of slits 220, 320 that are substantially parallel to each other. This can divide the necking region of at least one adhesive member 210, 310 into a plurality of smaller necking regions with reduced cross-sectional areas. Therefore, at least one adhesive member 210, 310 of the present disclosure can further reduce the magnitude of the pulling force F required to peel at least one adhesive member 210, 310.

[0139] In some examples, when a pulling force F is applied to at least one tab 230, 330, a plurality of smaller necked regions with reduced cross-sectional areas created in at least one adhesive member 210, 310 by the plurality of slits 220, 320 may be activated or stretched individually, sequentially, or in parallel. Additionally, in some examples, at least one tab 230, 330 may include one or more tabs attached to each of the plurality of adhesive regions 256 to assist in removing at least one adhesive member 210, 310. In some examples, the plurality of smaller necked regions with reduced cross-sectional areas may require a lower pulling force F to remove at least one adhesive member 110, 210, 310, 410, 510, 610 from each of at least one substrate 104, 404, 504, 604 and the outer surface 102.

[0140] It should be noted that the at least one slit 120, 220, 320, 420, 520 of at least one adhesive member 110, 210, 310, 410, 510, 610 may not significantly reduce the adhesion of the at least one adhesive member 110, 210, 310, 410, 510, 610 to the external surface 102 (such as the skin of a user), but facilitates the peeling of the at least one adhesive member 110, 210, 310, 410, 510, 610 from each of the at least one substrate 104, 404, 504, 604 and the external surface 102 without any significant damage or residue. In addition, when the outer surface 102 is the user's skin, the at least one slit 120, 220, 320, 420, 520 can allow moisture to be transmitted through the at least one adhesive member 110, 210, 310, 410, 510, 610, thereby improving the permeability and breathability of the at least one adhesive member 110, 210, 310, 410, 510, 610.
