AI Technical Summary
Cigarette boxes are prone to getting wet in humid environments, causing cigarettes to bend and the box to collapse. Existing frame paper lacks waterproofing capabilities.
Design a moisture-proof cigarette frame paper, including a moisture-absorbing strip and a snap-fit part. It is connected to the inside of the cigarette box through a snap-fit ear to ensure the friction between the moisture-absorbing strip and the box lid, preventing water from seeping in, and the snap-fit part prevents water from being squeezed out.
It effectively prevents water from entering through the gaps in the cigarette box, keeps the cigarettes dry and maintains the shape of the cigarette box, and avoids improper sealing and water squeezing out again.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of frame paper technology, specifically to a moisture-proof cigarette frame paper. Background Technology
[0002] The cigarette pack frame is an essential material for hard-pack tobacco products, serving to support the packaging. It's typically glued to the inner wall of the cigarette pack. However, because there's a gap between the lid and the pack body, water can easily seep into the pack when handled with wet hands or placed on a damp surface. This water then seeps through the gap between the frame and the pack, wetting the cigarettes inside. Furthermore, since the inner side of the pack isn't waterproof, absorbing water can cause the pack to collapse and the cigarettes to bend. Utility Model Content
[0003] To address the aforementioned technical problems, this utility model provides a moisture-proof cigarette frame paper. Technical solution
[0004] A moisture-proof cigarette frame paper is inserted inside the opening of a cigarette box. The cigarette frame paper includes a frame paper body one and a frame paper body two. The frame paper body one includes a front end and two outer portions one symmetrically arranged on both sides of the front end. The frame paper body two includes a rear end and two outer portions two symmetrically arranged on both sides of the rear end. The front end and the rear end are opposite each other, and the two outer portions two are respectively attached to the inner surfaces of the two outer portions one. There is a gap between the rear end face of the outer portion one and the outer surface of the rear end, and a vertical moisture-absorbing cotton strip one is provided in the gap. A moisture-absorbing cotton strip two is provided on the outer surface of the junction of the frame paper body one and the opening of the cigarette box.
[0005] Furthermore, the second outer part is provided with an outwardly protruding plug ear, which is inserted into the plug hole on the first outer part.
[0006] Furthermore, the top of the front end is provided with a recessed notch, and the bottom of the front end is provided with a convex protrusion.
[0007] Furthermore, the first absorbent cotton strip is sandwiched between the second frame paper body and the cigarette box body; the second absorbent cotton strip is attached to the top of the cigarette box body or sandwiched between the first frame paper body and the cigarette box body.
[0008] In one embodiment of this utility model, after the lid of the cigarette box is closed, there is friction between it and the first and second absorbent cotton strips.
[0009] As another embodiment of this utility model, the outer surface of the frame paper body one is also provided with a snap-fit part that protrudes outward. The outer edge of the snap-fit part extends beyond the outer surfaces of the first and second absorbent cotton strips. After the lid of the cigarette box is closed, there is friction between it and the snap-fit part.
[0010] Preferably, there are three snap-fit parts, which are respectively disposed on the front end and the two outer parts.
[0011] Furthermore, the outermost part one and the outermost part two are bonded together with glue, and the rear end and the front end are bonded to the cigarette box body with glue.
[0012] Beneficial effects:
[0013] This invention provides a moisture-proof cigarette holder frame with two absorbent strips. These prevent water from entering the cigarette box through the gap between the box body and the lid, thus avoiding moisture on the cigarettes or the inner surface of the box, which could affect the quality of the cigarettes and the shape of the box. Because the absorbent strip is positioned at the corner of the frame near the hinge of the lid, the frame at that corner is offset inwards from the lid. Unlike existing frame frames, this avoids the possibility of the frame folding outwards at the corner, preventing the lid from closing properly. Additionally, a locking mechanism prevents water from being squeezed out after the cigarette box and lid are closed, thus preventing the absorbed water from being expelled.

[0016] The present invention will now be described in detail with reference to the accompanying drawings.
[0017] As attached Figure 1 To be continued Figure 5 . Specific implementation examples:
[0019] A moisture-proof cigarette frame paper is inserted inside the opening of a cigarette box body 1. The cigarette frame paper includes a frame paper body 1 2 and a frame paper body 2 3. The frame paper body 1 2 includes a front end 21 and two outer parts 22 symmetrically arranged on both sides of the front end 21. The frame paper body 2 3 includes a rear end 31 and two outer parts 32 symmetrically arranged on both sides of the rear end 31. The front end 21 and the rear end 31 are opposite each other, and the two outer parts 32 are respectively attached to the inner surfaces of the two outer parts 22. There is a gap between the rear end face of the outer part 22 and the outer surface of the rear end 31. A vertical moisture-absorbing cotton strip 4 is provided in the gap. A moisture-absorbing cotton strip 5 is provided on the outer surface at the junction of the frame paper body 1 2 and the opening of the cigarette box body 1.
[0020] The outer part 2 32 is provided with an outwardly protruding insertion ear 33, which is inserted into the insertion hole 23 on the outer part 1 22. The insertion ear 33 is formed by a portion of the outer part 2 32 being cut outward and protruding outward. The specific cut shape can be C-shaped or arc-shaped, keeping a portion connected to the outer part 2 32.
[0021] The top of the front end 21 is provided with a recessed notch 6, which makes it easy to take out cigarettes. The bottom of the front end 21 is provided with a protruding part 7, which extends into the inside of the box body 1, and can prevent the front end face of the box body 1 from being deformed due to inward force.
[0022] Moisture-absorbing swab 4 is sandwiched between the frame paper body 2 3 and the cigarette box body 1; moisture-absorbing swab 5 is attached to the top of the cigarette box body 1 or sandwiched between the frame paper body 2 and the cigarette box body 1. Since moisture-absorbing swab 4 and moisture-absorbing swab 5 protrude from the outside of the frame paper body 2, there will be friction between the lid of the cigarette box body 1 (not shown in the figure) and moisture-absorbing swab 4 and moisture-absorbing swab 5 after it is closed. This friction can prevent the lid from opening automatically after it is closed.
[0023] However, when the lid is closed, it will also squeeze the absorbent cotton strips 4 and 5, which will cause the absorbed water to be squeezed out, thus making the cigarette wet. To address this, the outer surface of the frame paper body 2 is also provided with an outwardly protruding latching part 8. The outer edge of the latching part 8 extends beyond the outer surface of the absorbent cotton strips 4 and 5. When the lid of the cigarette box 1 is closed, there is friction between it and the latching part 8, which can prevent the water absorbed by the absorbent cotton strips 4 and 5 from being squeezed out.
[0024] Preferably, there are three snap-fit parts 8, which are respectively disposed on the front end 21 and the two outer parts 22. The snap-fit parts 8 are formed by cutting the frame paper body 2 and folding it outwards. The shape of the cut can be C-shaped or arc-shaped, keeping a part of it connected to the frame paper body 2, and the direction is upward when folded.
[0025] The outer part 1 22 and the outer part 2 32 are glued together, and the rear end 31 and the front end 21 are glued to the cigarette box body 1.
[0026] Although the present invention has been disclosed above with reference to preferred embodiments, these are not intended to limit the present invention. Anyone skilled in the art can make various changes or modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope of protection of the claims of this application.
