[0028] In addition, the terms "first", "second", and "third" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first", "second", and "third" may explicitly or implicitly include at least one of the features. In the description of the present utility model, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.
[0029] The utility model provides a protective film that is released through a connection point, which includes a protective film coil, which includes a plurality of punching areas connected in sequence, a plurality of intermittently arranged punching holes are opened on the protective film coil on each of the punching areas, and an easily torn connection point is retained between two adjacent punching holes, and the plurality of intermittently arranged punching holes are sequentially enclosed to form a protective film body.
[0030] Its structure has only one layer of protective film coil, and the protective film coil at the punching hole is punched out. When punching, the punching hole is used to punch out the shape of the protective film body, and several connection points that are easy to tear off are reserved between adjacent punching holes. When in use, the protective film body is torn off through the connection points. At this time, the connection points are broken, and the protective film body is separated from the protective film coil, thereby obtaining a complete protective film body. It saves the material of the light release film, greatly reduces the material cost, and avoids the waste of film materials. It is very environmentally friendly and improves the competitiveness of the product.
[0031] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings. The present invention is described in detail below in conjunction with the accompanying drawings and embodiments, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limitations on the present invention.
[0032] Example 1
[0033] See also Figures 1 to 2 , a protective film that is released through a connection point 2 provided by the utility model, comprising a protective film coil 100, the protective film coil 100 comprising a plurality of punching areas connected in sequence, a plurality of intermittently arranged punching holes 1 are opened on the protective film coil 100 on each punching area, and an easily torn connection point 2 is reserved between two adjacent punching holes 1, and a plurality of intermittently arranged punching holes 1 are sequentially enclosed to form a protective film body 3. Its structure has only one layer of protective film coil 100, and the protective film coil 100 at the punching hole 1 is punched out. When punching, the shape of the protective film body 3 is punched out by the punching hole 1, and a plurality of easily torn connection points 2 are reserved between adjacent punching holes 1. When in use, the protective film body 3 is torn off through the connection point 2, at which time the connection point 2 is broken, and the protective film body 3 is separated from the protective film coil 100, thereby obtaining a complete protective film body 3. It saves the material of the light release film, greatly reduces the material cost, and avoids the waste of film material, which is very environmentally friendly and improves the competitiveness of the product.
[0034] Furthermore, the size, position, number and shape of the connection point 2 can be adjusted and optimized according to actual needs.
[0035] Furthermore, the front side of the protective film body 3 is a weakly adhesive side, and the back side of the protective film body 3 is a non-adhesive side. The protective film roll 100 is in a roll form, and the weakly adhesive side is attached to the non-adhesive side.
[0036] Furthermore, the connection point 2 is in an X-shape to facilitate release.
[0037] Further, a film tearing handle 4 is provided on the protective film body 3 to facilitate subsequent film tearing. Further, the film tearing handle 4 is colored to facilitate identification.
[0038] Furthermore, the film tearing handle 4 is red in color for easy identification.
[0039] Example 2
[0040] See also Figures 3 to 5 As a further optimization scheme of Example 1, in this embodiment, a "concave" shaped through hole 5 is opened on the protective film body 3, and the residual material of the "concave" shaped through hole 5 forms a film tearing handle 4, so there is no need to add a film tearing handle 4 on the periphery of the protective film body 3. Therefore, the film tearing handle 4 will not be unable to be placed due to the limitation of the peripheral space, avoiding the situation where tweezers need to be used to lift the film when the peripheral space is limited, thereby saving labor costs; and the material of the peripheral film tearing handle 4 can be omitted, which can greatly reduce the material cost.
[0041] Furthermore, the waste material 6 of the “concave”-shaped through hole 5 remains on the protective film body 3. Before the protective film body 3 is torn off, the waste material 6 is still connected to the protective film body 3, which can effectively prevent dust or other particles from entering the product surface. Since the waste material 6 is still connected to the protective film body 3, it is difficult to tear off the film tearing handle 4 at this time, so an adhesive area 7 can be set on the upper surface of the waste material 6, preferably glue, but not limited to this. When tearing off the upper protective film body 3, the waste material 6 can be torn off with the help of glue first, and then the protective film body 3 can be torn off with the film tearing handle 4.
[0042] Furthermore, a concave through hole 5 is provided at the edge of the protective film body 3 , so that the protective film body 3 is easier to tear off, and the tearing handle 4 is prevented from being damaged due to high tearing difficulty.
[0043] Furthermore, each corner of the "concave"-shaped through hole 5 is provided with a rounded corner, so that the stress during film tearing is not concentrated at the corner, thereby avoiding the film tearing handle 4 from being torn due to stress concentration, and further improving the working efficiency.
[0044] Furthermore, the radius of the rounded corner is 1 mm.
[0045] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection, an electrical connection, or communication with each other; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0046] Obviously, the embodiments described above are only some embodiments of the present application, rather than all embodiments. The preferred embodiments of the present application are given in the accompanying drawings, but they do not limit the patent scope of the present application. The present application can be implemented in many different forms. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present application more thorough and comprehensive.
