[0024] The technical scheme in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.
[0025] Referring to Figure 1 - Figure 3 A protection film structure for cigarette mouthpiece packaging, which comprises a protection film body 1, one side of the protection film body 1 is fixedly connected with a first edge 2, the other side of the protection film body 1 is fixedly connected with a second edge 3, the surface of the second edge 3 is provided with a first rough part 5 in the middle, the surface of the first edge 2 is provided with a plurality of second rough parts 6, the plurality of second rough parts 6 are evenly distributed at equal intervals, the second rough part 6 in the middle of the first edge 2 is spaced apart from the second rough parts 6 on both sides by 2 mm, the common length of the protection film body 1 and the first edge 2 is 22 mm, and the length of the first edge 2 and the second edge 3 is 10 mm.
[0026] According to the fact that the circumference of the mainstream cigarette filter 7 on the market is between 20-24 mm, by presetting the common length of the protection film body 1 and the first edge 2 as 22 mm and the length of the second edge 3 and the first edge 2 as 10 mm, it can be ensured that the entire protection film has an overlapping area of 8-12 mm after covering the cigarette filter 7, the plurality of second rough parts 6 arranged at equal intervals make the first rough part 5 and the second rough part 6 in the middle rub and contact when the circumference of the filter is 22 mm, at this time, it is the initial state, when the circumference of the filter is 20 mm or 24 mm, the first rough part 5 and the second rough parts 6 on both sides rub and contact, at this time, it is the extreme state, and when the circumference of the filter is any value between 22-24 mm, there is the second rough part 6 corresponding to the first rough part 5 to rub and contact, so the situation that the rough surface and the smooth surface contact does not occur, the inevitability of rubbing and contacting is ensured, and then the firmness of the protection film adhesion is ensured.
[0027] Specifically, the second edge 3 is fixedly connected with an extension strip 4, the extension strip 4 is a low surface energy material, the extension strip 4 can be polyethylene film, polypropylene film or polytetrafluoroethylene film, etc., when the overlapping area of the first edge 2 and the second edge 3 is adhered by heat shrink technology, since the extension strip 4 is an extension of the second edge 3 itself, beyond the heat shrink range, the extension strip 4 will not be adhered to the surface of the protective film body 1 or the first edge 2, and the low surface of the extension strip 4 reduces the adsorption force of the protective film body 1 or the first edge 2 to the extension strip 4, realizes the easy tearing of the protective film, facilitates the separation of the protective film and the filter tip, and provides a convenient use experience for the user.
[0028] More specifically, the first edge 2 and the second edge 3 are adhered by heat shrink technology, which is suitable for mainstream protective film packaging machines and improves packaging efficiency.
[0029] Meanwhile, it should be noted that the width of the protective film body 1, the first edge 2, the second edge 3 and the extension strip 4 is 28mm, the length of the mainstream cigarette filter tip 7 on the market is 25-30mm, and the preset 28mm makes the entire protective film applicable to all mainstream cigarettes on the market.
[0030] The working principle of the utility model is as follows: taking the first edge 2 as an endpoint, then winding the protective film body 1 on the cigarette filter tip 7, after winding a turn, the second edge 3 will cover the first edge 2, and according to the different circumferences of the cigarette filter tip 7, the first rough part 5 will be attached to the corresponding second rough part 6, at this time, the first edge 2 and the second edge 3 are adhered by heat shrink technology, at this time, the tiny convex particles on the first rough part 5 will be nested with the tiny grooves on the second rough part 6, and the firmness of the adhesion is strengthened, that is, the packaging of the entire protective film structure is completed, and due to the low surface energy characteristics of the extension strip 4, the entire protective film has easy tearing, providing a convenient use experience for the user.
[0031] Referring to Figure 1 , the protective film body 1, the first edge 2, the second edge 3 and the extension strip 4 are sleeved on the cigarette filter tip 7, the circumference of the cigarette filter tip 7 is 22mm, it can be seen that the first edge 2 and the second edge 3 completely overlap, and the extension strip 4 ensures the easy tearing of the entire protective film.
[0032] Meanwhile, it should be noted that the first rough part 5 is a tiny convex particle, and the second rough part 6 is a tiny groove, when the first rough part 5 and the second rough part 6 are in frictional contact, on the microscopic level, the tiny convex particles and the tiny grooves are nested with each other, compared with the contact between the smooth film and the rough surface, the frictional contact mode makes the actual contact area larger, and the adhesion is more firm.
[0033] The basic principle, main features and advantages of the present application are shown and described above. Those skilled in the art should understand that the present application is not limited by the above examples, and the above examples and descriptions in the specification are only to illustrate the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the claimed present application.
