DETAILED DESCRIPTION OF THE INVENTION
[0041] Reference will now be made in detail to embodiments illustrated in the accompanying drawings. Wherever possible, the same reference numbers are used in the drawings and the description to refer to the same or like parts. In the drawings, the shape and thickness may be exaggerated for clarity and convenience. This description will be directed in particular to elements forming part of, or cooperating more directly with, methods and apparatus in accordance with the present disclosure. It is to be understood that elements not specifically shown or described may take various forms well known to those skilled in the art. Many alternatives and modifications will be apparent to those skilled in the art, once informed by the present disclosure.
[0042]
[0043] In the embodiment, the tearing portion 120 includes, but not limited to, polyethylene terephthalate (PET). The tearing portion 120 is preferably made of light-weight material with certain toughness and difficultly ruptured characteristics. In the embodiment, the tearing portion 120 is a film layer formed by extending the first protective layers 112 and 113 of the first connecting section 110. In the embodiment, the first connecting section 110 has a length of 10 mm. The first adhesive section 100 has a width of 15 mm that is connected to the first connecting section 110, but the present invention is not limited thereto. The areas and the lengths of the first connecting section 110 and the first adhesive section 100 are adaptable according to requirements. For example, the first connecting section 110 may have a length of 1˜50 mm. The first adhesive section 100 may have a width of 5˜30 mm that is connected to the first connecting section 110. The first adhesive section 100 may have an adhering length of 10˜300 mm. The tearing portion 120 may have a length of 10˜500 mm. The present invention is not limited to the foregoing length or width.
[0044] When the removable adhesive member of the present invention is applied to products, the removable adhesive member may adhere to the product in a larger range or a longer length. Besides, the removable adhesive member may adhere to the product along the same direction or different directions (e.g., horizontal direction or vertical direction). In order to remove the removable adhesive member merely with the tearing portion, multiple adhesive sections can be used and an extending portion is connected to the adhesive sections along the same direction or different directions. As a result, the adhering area and strength of the adhesive section can be reduced, such that it takes less time to remove the removable adhesive member.
[0045]
[0046] In detailed, the second adhesive section 140 of the embodiment is implemented with a double-sided tape. The two surfaces of the second adhesive section 140 adhere to objects. The second connecting section 130 includes a second adhesive layer 131 and two second protective layers 132 and 133. The first adhesive section 100 extends along the second direction (i.e., horizontal direction in the figure) to form the second adhesive layer 131. The second protective layers 132 and 133 are respectively laminated to two opposite surfaces of the second adhesive layer 131. The third connecting section 150 includes a third adhesive layer 151 and two third protective layers 152 and 153. The second adhesive section 140 extends along the second direction (i.e., horizontal direction in the figure) to form the third adhesive layer 151. The third protective layers 152 and 153 are respectively laminated to two opposite surfaces of the third adhesive layer 151. One side of the second connecting section 130 is connected to the first adhesive section 100, and another side of the second connecting section 130 is connected to one side of the extending section 160 toward the first direction. One side of the third connecting section 150 is connected to the second adhesive section 140, and another side of the third connecting section 150 is connected to another side of the extending section 160 toward the second direction. In the embodiment, the first direction and the second direction are the same directions.
[0047] In another embodiment, the first direction and the second direction may be different directions.
[0048] In the present invention, the extending section 160 may be a film layer formed by extending the second protective layers 132 and 133 or the third protective layers 152 and 153 or a wire fixed between the second connecting section 130 and the third connecting section 150. The wire may be, but not limited to, an iron wire or a cotton thread. Besides, the tearing portion 120 may be a double layered film (e.g., the first embodiment or the second embodiment). The tearing portion 120 may be implemented with various wires such as iron wires or cotton threads, but the present invention is not limited thereto. The tearing portion 120 is made of material having good toughness and anti-pulling and difficultly ruptured characteristics.
[0049]
[0050] In order to improve the anti-pulling strength, the tearing portion 120 and the first connecting section 110 are provided with a transitional portion therebetween.
[0051] When the tearing portion 120 is implemented with a wire, multiple adhesive sections of the removable adhesive member are connected through an extending portion along the same direction or different directions. Thus, the removable adhesive member may adhere to an object in a longer length or a larger range. Besides, the removable adhesive member may adhere to an object along the same direction or different directions. The removable adhesive member is removed merely with the tearing portion. As a result, the adhering area and strength of the adhesive section can be reduced, such that it takes less time to remove the removable adhesive member.
[0052]
[0053] As mentioned above, the tearing portion 120 of the present invention is not limited to a film layer or a wire. The tearing portion 120 is made of material having toughness and difficultly ruptured characteristics. The material of the tearing portion 120 depends on requirements of products. The tearing part 120 usually needs to be exposed outside the product in order to conveniently catch and tear off the tearing portion 120. Some products such as notebook computers need to hide the tearing portions. The wire is softer than the film layer and easily hidden in these products. Moreover, the wire is easily shaped and arranged. The wire is easily designed to have angles and able to bend. On the contrary, it is time-consuming to accurately design a film layer.
[0054] The removable adhesive member of the present invention can be further applied to a display device, such as the liquid crystal display device of a notebook computer or a tablet computer, a light emitting display device, or an organic light emitting display device. The removable adhesive member is especially used as a back adhesive on the back of the display device. Thus, the display device is assembled with a back cover through the removable adhesive member, such that they can be rapidly disassembled without causing damage to the products.
[0055]
[0056]
[0057]
[0058] In conclusion, the removable adhesive member of the present invention includes the tearing portion, the connecting section, and the adhesive section. The tearing portion is conveniently pulled by a user to remove the removable adhesive member. The tearing portion can reduce the difficulty and time in removing the adhesive member. Besides, the connecting section is firmly connected between the adhesive section and the tearing section, so as to avoid rupture during a removing process, thereby facilitating to proceed with a disassembling work. Additionally, the removable adhesive member of the present invention has multiple adhesive sections required for a longer adhering length, a larger adhering range, or a larger curved angle. The extending portion, connected between every two adhesive sections, reduces the area of the adhesive section and the difficulty in removing the removable adhesive member.
[0059] The removable adhesive member of the present invention is suitable for assembling the display device. The removable adhesive member is especially suitable for adhering to the back cover and the display module using the adhesive assembling method. The display module may be a liquid crystal display module or a touch display module. When the back cover and the display module are disassembled, the removable adhesive member is easily removed to facilitate to rapidly disassemble products without causing damage to the products.
[0060] The embodiments described above are only to exemplify the present invention but not to limit the scope of the present invention. Therefore, any equivalent modification or variation according to the shapes, structures, features, or spirit disclosed by the present invention is to be also included within the scope of the present invention.
