DETAILED DESCRIPTION
[0033] The following is combined with Figure 1-6 This application is described in further detail.
[0034] Embodiment 1:
[0035] The present application embodiment discloses a tape joint of a protective film, referring to Figure 1 The invention comprises a base layer 1, which is made of PVC material. A first connecting component 2 is provided at one end of the base layer 1 in the length direction, and a second connecting component 3 is provided at the other end. The first connecting component 2 and the second connecting component 3 are located on the same surface of the base layer 1.
[0036] Reference Figure 1 The first connection component 2 includes a release film 21, a glue layer 22 and a sealing glue layer 23. The release film 21 is connected to the base layer 1; the glue layer 22 is made of PET material, and the glue layer 22 is connected to the surface of the release film 21 away from the base layer 1; the sealing glue layer 23 is a release paper layer, and the sealing glue layer 23 is connected to the surface of the glue layer 22 away from the base layer 1. Since the sealing glue layer 23 is a release paper layer, the sealing glue layer 23 is easy to tear off from the glue layer 22; since the release film 21 is provided, the glue layer 22 is easy to tear off from the base layer 1.
[0037] Reference Figure 1 The second connecting component 3 includes a second glue layer 31 and a second sealing glue layer 32. The second glue layer 31 is made of the same material as the first glue layer 22. The second glue layer 31 is connected to the base layer 1 and is located on the same surface of the base layer 1 as the first glue layer 22. The second sealing glue layer 32 is a release paper layer. The second sealing glue layer 32 is connected to the surface of the second glue layer 31 facing away from the base layer 1, so the second sealing glue layer 32 can be easily torn off from the second glue layer 31.
[0038] Reference Figure 2 and Figure 3When the user uses the protective film 5, the user first unfolds the protective film 5 from the paper tube 7, and then wraps the unfolded protective film 5 on the surface of the product. After wrapping, a dot-break dot-mark line 6 is found as a breaking line. The protective film 5 on one side of the breaking line close to the product is the protective film 5 wrapped on the surface of the product, and the other side is the protective film 5 wrapped on the paper tube 7; the user tears off the sealing glue layer 1 23 and the sealing glue layer 2 32 from the glue layer 1 22 and the glue layer 2 31 respectively, and then adheres the glue layer 1 22 to the position of the protective film 5 on the surface of the product close to the breaking line, and adheres the glue layer 2 31 to the position of the protective film 5 on the paper tube 7 close to the breaking line. At this time The base layer 1 is in a horizontal state, and the user keeps the position of the protective film 5 on the paper tube 7 unchanged, and at the same time pulls the protective film 5 on the product surface away from the paper tube 7, and the protective film 5 on the product surface will be separated from the protective film 5 on the paper tube 7 along the breaking line. At the same time, the protective film 5 on the product surface will tear the second adhesive layer 31 off the base layer 1, so that the second adhesive layer 31 is adhered to the breaking part of the protective film 5 on the product surface; in summary, when the protective film 5 on the product surface is separated from the protective film 5 on the paper tube 7, the gluing of the breaking part of the protective film 5 on the product surface can be completed at the same time, thereby facilitating the gluing of the protective film 5 on the product surface.
[0039] Reference Figure 2 and Figure 3 , since the sealing glue layer 1 23 is attached to the adhesive layer 1 22, and the sealing glue layer 2 32 is attached to the adhesive layer 2 31, it is inconvenient for the user to tear the sealing glue layer 1 23 and the sealing glue layer 2 32 off the adhesive layer 1 22 and the adhesive layer 2 31. In order to solve the above problem, a tearing strip 4 is integrally formed on the edge of the sealing glue layer 1 23 and the sealing glue layer 2 32. Since the tearing strip 4 is not connected to the adhesive layer 1 22 or the adhesive layer 2 31, the user can easily pinch the tearing strip 4, and then tear the sealing glue layer 1 23 and the sealing glue layer 2 32 off the adhesive layer 1 22 and the adhesive layer 2 31 by pulling the tearing strip 4, which is convenient and quick to operate.
[0040] Reference Figure 1 The tear strip 4 on the sealing layer 1 23 is located at the corner of the sealing layer 1 23 , and the tear strip 4 on the sealing layer 2 32 is located at the corner of the sealing layer 2 32 . The above arrangement can make it easier and more labor-saving for the user to tear off the sealing layer 1 23 and the sealing layer 2 32 .
[0041] Reference Figure 1 and Figure 3, the length of the adhesive layer 1 22 and the adhesive layer 2 31 along the width direction of the base layer 1 is smaller than the width of the base layer 1, and the adhesive layer 1 22 and the adhesive layer 2 31 are both located in the middle position of the width direction of the base layer 1. When the user respectively adheres the adhesive layer 1 22 and the adhesive layer 2 31 to the protective film 5 on the surface of the product and the protective film 5 on the paper tube 7, the user can pinch the base layer 1 on both sides of the adhesive layer 1 22 and the adhesive layer 2 31 along the width direction of the base layer 1 with fingers, thereby avoiding the contact between the user's fingers and the adhesive layer 1 22 and the adhesive layer 2 31, which can facilitate the user to adhere the adhesive layer 1 22 and the adhesive layer 2 31 to the protective film 5 on the surface of the product and the protective film 5 on the paper tube 7 respectively.
[0042] The implementation principle of the tape joint of a protective film in the embodiment of the present application is as follows: when in use, the user unfolds the protective film 5 from the paper tube 7, and wraps the unfolded protective film 5 on the surface of the product, and then selects a dot-break dot-mark line 6 as the breaking line, and the side of the breaking line close to the product is the protective film 5 on the surface of the product, and the other side is the protective film 5 on the paper tube 7; the user tears off the sealing glue layer 1 23 and the sealing glue layer 2 32 from the glue layer 1 22 and the glue layer 2 31, and then adheres the glue layer 1 22 to the protective film 5 on the surface of the product close to the breaking line, and adheres the glue layer 2 31 to the protective film 5 on the paper tube 7 close to the breaking line. The protective film 5 on the paper tube 7 is kept in the same position, and the protective film 5 on the product surface is pulled away from the paper tube 7. The protective film 5 on the product surface will be separated from the protective film 5 on the paper tube 7 along the breaking line, and the adhesive layer 22 will follow the protective film 5 on the product surface to separate from the base layer 1. In summary, while the protective film 5 on the product surface is separated from the protective film 5 on the paper tube 7, the breaking part of the protective film 5 on the product surface can be glued. Therefore, the present application has the effect of facilitating the user to glue the breaking part of the protective film 5 on the product surface.
[0043] Embodiment 2:
[0044] Reference Figure 4 The difference between this embodiment and the first embodiment is that the first connecting component 2 and the second connecting component 3 are respectively located on different surfaces of the base layer 1.
[0045] Reference Figure 5 and Figure 6When in use, the user adheres the adhesive layer 1 22 to the protective film 5 on the surface of the product near the breaking line, and adheres the adhesive layer 2 31 to the protective film 5 on the paper tube 7 near the breaking line. At this time, the base layer 1 is in a bent state, and then the user keeps the position of the protective film 5 on the paper tube 7 unchanged, and at the same time pulls the protective film 5 on the surface of the product away from the paper tube 7. The protective film 5 on the surface of the product will be separated from the protective film 5 on the paper tube 7 along the breaking line, and at the same time, the adhesive layer 1 22 will follow the protective film 5 on the surface of the product to separate from the base layer 1. Since the base layer 1 is in a bent state, the adhesive layer 1 22 will be easier to separate from the base layer 1, thereby making it more convenient to glue the broken part of the protective film 5 on the surface of the product.
[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
