Detailed Implementation

[0035] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0036] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] Reference manual attached Figure 1 , attached Figure 1 This is a schematic diagram of the assembly of the tear-off cigarette box packaging film provided in the embodiments of this application. Figure 2 This is a top view of the tear-off cigarette box packaging film and the cigarette box assembly provided in the embodiment of this application. A tear-off cigarette box packaging film is used to wrap the surface of the cigarette box 1, including: a front film 2 and a rear film 3 that are alternately covered on the side of the cigarette box.

[0038] The front film 2 is provided with a first tear line 21 that is horizontally positioned relative to the cigarette box 1. The front film 2 can be separated vertically by peeling off the first tear line 21. One end of the first tear line 21 is located on one side edge of the front film 2, and the other end of the first tear line 21 extends out to the outside of the other side edge of the front film 2 through the first pull head 22.

[0039] The rear film 3 is provided with a second tear line 31 that is horizontally positioned relative to the cigarette box 1. The rear film 3 can be separated vertically by peeling off the second tear line 31. One end of the second tear line 31 is located on one side edge of the rear film 3, and the other end of the second tear line 31 extends out to the outside of the other side edge of the rear film 3 through the second pull head 32.

[0040] The arrangement of the first tear line 21 and the second tear line 31 can refer to the conventional gold tear line arrangement of cigarette boxes in the prior art, ensuring that they have toughness and good adhesion. The pull head of the tear line extends to the outside of the packaging film for easy gripping and tearing to remove the packaging film.

[0041] The packaging film of this application works well when used in some special-shaped cigarette boxes, such as cigarette boxes with smoke outlets at both the top and bottom, and drawer-style cigarette boxes with transparent top and bottom. The placement of two tear lines, tailored to the specific type of cigarette box, simplifies the removal of the packaging film, greatly improving convenience and user experience.

[0042] Furthermore, the front film 2 includes a first plane 23 and a first bending surface 24 and a second bending surface 25 folded and disposed on both sides of the first plane 23; the rear film 3 includes a second plane 33 and a third bending surface 34 and a fourth bending surface 35 folded and disposed on both sides of the second plane 33.

[0043] The first plane 23 is attached to the front of the cigarette box, and the second plane 33 is attached to the back of the cigarette box; the inner side of the first bent surface 24 is attached to the first side wall of the cigarette box, and the third bent surface 34 covers the outer side of the first bent surface 24; the inner side of the fourth bent surface 35 is attached to the second side wall of the cigarette box, and the second bent surface 25 covers the outer side of the fourth bent surface 35.

[0044] Furthermore, the first tear line 21 extends from the edge of the first bending surface 24 across the first plane 23 to the outer edge of the second bending surface 25 and extends out of the first pull head 22;

[0045] The second tear line 31 extends from the edge of the fourth bending surface 35 across the second plane 33 to the outer edge of the third bending surface 34 and extends out of the second pull head 32;

[0046] The horizontal plane where the first tear line 21 is located is higher than the horizontal plane where the second tear line 31 is located. This achieves the effect of the front film 2 separating from the upper part of the cigarette box 1, and the rear film 3 separating from the lower part of the cigarette box 1. This facilitates adaptation to various special-shaped cigarette box packaging on the market.

[0047] Furthermore, the bending lines at the folds of the first plane 23, the first bending surface 24, and the second bending surface 25 are respectively attached to the vertical edges on both sides of the front of the cigarette box 1.

[0048] The bending lines at the folds of the second plane 33, the third bending surface 34, and the fourth bending surface 35 correspond and are attached to the vertical edges on both sides of the back of the cigarette box 1. This ensures that the front film 2 and the back film 3 maintain an alternating overlap, and that the lines are aligned to center the packaging film and the cigarette box 1. This standardizes the cigarette box packaging and facilitates mass production.

[0049] Furthermore, the top and bottom of the aforementioned front film 2 are each provided with a fifth folded surface, and the top and bottom of the aforementioned rear film 3 are each provided with a sixth folded surface; the aforementioned fifth folded surfaces and the aforementioned sixth folded surfaces cooperate to seal the top and bottom of the aforementioned cigarette box 1. The aforementioned fifth folded surface includes the top folded surface and the bottom folded surface of the front film 2, and the sixth folded surface includes the top folded surface and the bottom folded surface of the rear film 3. The two planes cooperate to seal both ends of the cigarette box 1, and make the front film 2 and the rear film 3 completely form a complete packaging film.

[0050] A packaging method, applied to any of the tear-off cigarette box packaging films described above, comprising:

[0051] Step 1: Attach the inner side of the front film 2 away from the first pull tab 22 to one side wall of the cigarette box 1, and attach the inner side of the rear film 3 away from the second pull tab 32 to the other side wall of the cigarette box 1.

[0052] Step 2: Obtain the horizontal position of the first tear line 21 on the front film 2, and ensure that the horizontal position of the second tear line 31 on the rear film 3 is lower than the first tear line 21.

[0053] Step 3: The front film 2 is provided with the side of the first zipper 22 covering the side outer wall of the rear film 3 away from the second zipper 32, and the rear film 3 is provided with the side of the second zipper 32 covering the side outer wall of the front film 2 away from the first zipper 22.

[0054] Step 4: Attach the main plane of the front film 2 to the front of the cigarette box 1, and attach the main plane of the rear film 3 to the back of the cigarette box 1.

[0055] Step 5: Seal the top of the front membrane 2 with the top of the rear membrane 3, and seal the bottom of the front membrane 2 with the bottom of the rear membrane 3.

[0056] For step two, obtaining the horizontal position of the first tear line 21 on the front film 2 and ensuring that the horizontal position of the second tear line 31 on the rear film 3 is lower than the first tear line 21, specifically, the setting positions of the first tear line 21 and the second tear line 31 are changed according to the specific type of cigarette box 1.

[0057] Furthermore, the step of the front film 2 having the side of the first zipper 22 covering the side outer wall of the rear film 3 away from the second zipper 32, and the rear film 3 having the side of the second zipper 32 covering the side outer wall of the front film 2 away from the first zipper 22, includes: the front film 2 and the rear film 3 being heat-shrinked together by a soldering iron.

[0058] In practice, when heating and shrinking, the soldering iron should be kept in the temperature range of 110°C to 125°C to ensure that the front and back films adhere well together.

[0059] Furthermore, the steps of sealing the top of the front film 2 with the top of the rear film 3 and sealing the bottom of the front film 2 with the bottom of the rear film 3 include: sealing the top and bottom of the front film 2 and the rear film 3 by heat shrink molding with an electric soldering iron or by pressing with a sheet.

[0060] In practical use, the above-mentioned compression molding process requires folding one side first, pressing it down with a compression plate, then folding the other side over and pressing it down by hand, while simultaneously heating with a soldering iron to shrink and seal the film. The specific operation method can be found in existing technology and will not be repeated here.

[0061] Further, refer to the attached instruction manual. Figure 3 , Figure 3 This is a schematic diagram of the die-cutting production of the tear-off cigarette box packaging film provided in this application embodiment. Before the steps of attaching the inner wall of the front film 2 away from the first pull head 22 to one side wall of the cigarette box 1, and attaching the inner wall of the rear film 3 away from the second pull head 32 to the other side wall of the cigarette box 1, the process further includes: die-cutting the ends of the first tear line 21 and the ends of the second tear line 31 using a semi-circular arc die-cutting blade. In actual production, continuous die-cutting is performed using a mature die-cutting method. Figure 3 The die-cut notch 27 is processed so that it corresponds exactly to the protruding position of the first pull head 22, thereby improving efficiency.

[0062] It is foreseeable that the post-production film 3 can refer to the continuous die-cutting method of the pre-production film 2, which will not be elaborated further in this article.

[0063] Furthermore, after sealing the top of the front film 2 with the top of the rear film 3 and sealing the bottom of the front film 2 with the bottom of the rear film 3, the process further includes: inspecting the adhesion toughness of the first tear line 21 and the second tear line 31. This ensures product quality and guarantees a high yield rate.

[0064] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0065] The foregoing has provided a detailed description of the tear-off cigarette box packaging film and its packaging method provided in this application. Specific examples have been used to illustrate the principles and implementation methods of this application. The descriptions of the above embodiments are merely for the purpose of helping to understand the method and core ideas of this application. It should be noted that those skilled in the art can make various improvements and modifications to this application without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this application.
