Description

Technical Field

[0001] The utility model relates to the technical field of frame paper, and particularly relates to a frame paper with a composite buffer structure. Background Art

[0002] The frame paper for cigarettes is an essential material for the hard boxes of tobacco packaging. The frame paper is the main material used to make the frame of the cigarette box, and it has more supporting force than ordinary paper to support the frame shape of the cigarette box. It is one of the special papers for cigarette packaging.

[0003] The existing frame paper is usually made of a single layer of white cardboard, which is difficult to ensure the structural strength. It is still easy to deform when受力, resulting in the cigarette sticks being squeezed and damaged. Moreover, the lid of the cigarette box is easy to warp and open, so that moisture is easily introduced into the box body of the cigarette box, causing the cigarettes to get damp and making it difficult to provide better protection for the cigarette sticks. How to invent a frame paper with a composite buffer structure to improve these problems has become an urgent problem for those skilled in the art. Summary of the Utility Model

[0004] In order to make up for the above deficiencies, the utility model provides a frame paper with a composite buffer structure, aiming to improve the problems that the frame paper is still easy to deform when受力, resulting in the cigarette sticks being squeezed and damaged, and it is easy to make moisture enter the box body of the cigarette box, causing the cigarettes to get damp and making it difficult to provide better protection for the cigarette sticks.

[0005] The utility model is realized as follows:

[0006] The utility model provides a frame paper with a composite buffer structure, including a box body and a lid. The box body is connected with a frame component, and the frame component includes a support layer. The support layer is connected with a moisture-proof layer and a protective layer. An absorbent layer is arranged on one side of the protective layer. Reinforcement bars are arranged inside the support layer, and a sealing strip is connected to the moisture-proof layer.

[0007] Preferably, one end of the box body is rotatably connected with the lid, and the inner wall of the box body is fixedly adhered to the moisture-proof layer by glue.

[0008] Preferably, the moisture-proof layer is fixedly connected to one side of the support layer, and the side of the moisture-proof layer away from the support layer is fixedly connected to the sealing strip.

[0009] Preferably, a plurality of reinforcement bars are arranged inside the support layer in an array distribution. Convex bars are fixedly connected to both sides of the support layer, and the support layer is integrally arranged in a "匚" shape.

[0010] Preferably, the side of the support layer away from the moisture-proof layer is fixedly connected to the protective layer, and the thickness of the protective layer is the same as that of the moisture-proof layer.

[0011] Preferably, the protective layer is fixedly connected to the absorbent layer on the side away from the support layer.

[0012] The beneficial effects of this utility model are:

[0013] The support layer provides a stable support frame for the cigarette box. The evenly distributed reinforcing strips inside enhance the overall strength of the support layer, making it less prone to deformation under stress and preventing the cigarettes from being squeezed and damaged. The raised strips on both sides of the support layer not only increase the structural stability of the support layer, but also play a certain role in buffering, reducing the impact of external impacts on the cigarette box. At the same time, when the lid is closed, one end of the raised strip will rub against the inner wall of the lid, increasing the firmness of the lid when closed. The protective layer protects the cigarettes and can effectively prevent external sharp objects from scratching or damaging them. The water-absorbing layer is used to absorb the trace amounts of moisture that enter the cigarette box, keeping the inside of the cigarette box dry and preventing the cigarettes from getting damp.

[0020] To make the purpose, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the scope of protection of the present utility model.

[0021] Example, referring to Figures 1-4 , a frame paper with a composite buffer structure, including a box body 1 and a box cover 3. The box body 1 is connected with a frame component 2. The frame component 2 includes a support layer 22. The support layer 22 is connected with a moisture-proof layer 21 and a protective layer 23. An absorbent layer 24 is provided on one side of the protective layer 23. Reinforcement bars 25 are provided inside the support layer 22. The moisture-proof layer 21 is connected with a sealing strip 4.

[0022] Furthermore; one end of the box body 1 is rotatably connected to the box cover 3. The inner wall of the box body 1 and the moisture-proof layer 21 are fixedly adhered by glue; the moisture-proof layer 21 is fixedly connected to one side of the support layer 22. The side of the moisture-proof layer 21 away from the support layer 22 is fixedly connected to the sealing strip 4; a number of reinforcement bars 25 distributed in an array are provided inside the support layer 22. Protruding strips 5 are fixedly connected to both sides of the support layer 22. The support layer 22 is integrally arranged in a "C" shape; the side of the support layer 22 away from the moisture-proof layer 21 is fixedly connected to the protective layer 23. The thickness of the protective layer 23 is the same as the thickness of the moisture-proof layer 21; the side of the protective layer 23 away from the support layer 22 is fixedly connected to the absorbent layer 24.

[0023] It should be noted that: The moisture-proof layer 21 is the key part of the frame paper for moisture-proof. It is fixedly adhered to the inner wall of the box body 1 by glue to form a tightly fitting moisture-proof barrier. It uses moisture-proof materials with high barrier properties, such as special paper or plastic film coated with a moisture-proof coating. The moisture-proof coating is generally silicone, nano-silica, etc. These materials can effectively block external moisture from entering the cigarette case. The sealing strip 4 connected to the moisture-proof layer 21 further enhances the moisture-proof effect. It cooperates with the box cover 3 to fill the gap between the box cover 3 and the box body 1, preventing moisture from invading. The sealing strip 4 can be made of materials with good sealing performance such as rubber or silicone, and at the same time increases the firmness after the box cover 3 is closed, avoiding it from being opened. In addition, a special coating can be applied to the surface of the frame paper of some high-grade cigarette cases, such as an aluminized coating, which can enhance the barrier performance of the frame paper, block oxygen, moisture, and light, better protect the cigarettes, and extend the shelf life; or use an anti-counterfeiting coating, through special printing processes or adding anti-counterfeiting materials, such as fluorescent powder, color-changing ink, etc., to play an anti-counterfeiting role;

[0024] The support layer 22 is the structural foundation of the frame paper. It is arranged in a "匚" shape to provide a stable support frame for the cigarette case. The reinforcing strips 25 evenly distributed inside it enhance the overall strength of the support layer 22, making it not easily deformed when stressed and avoiding damage to the cigarette sticks due to extrusion. The support layer 22 is usually made of high-strength cardboard or fiberboard. The reinforcing strips 25 can be made of materials with high fiber content and good toughness, such as glass fiber, carbon fiber, etc. These materials can significantly improve the compressive and bending resistance of the support layer 22. The convex strips 5 on both sides of the support layer 22 not only increase the structural stability of the support layer 22 but also play a buffering role to a certain extent, reducing the impact of external forces on the cigarette case. At the same time, during the process of closing the lid 3, one end of the convex strip 5 will come into frictional contact with the inner wall of the lid 3, increasing the firmness when the lid 3 is closed;

[0025] The protective layer 23 is located on the side of the support layer 22 away from the moisture-proof layer 21 and is closely connected to the support layer 22. Its thickness is the same as that of the moisture-proof layer 21, serving to protect the cigarette sticks. It is made of materials with tough texture and good abrasion resistance, such as special paper or thin plastic sheets, which can effectively prevent scratches or damage to the cigarette sticks caused by external sharp objects. The water-absorbing layer 24 is arranged on one side of the protective layer 23 to absorb the trace moisture entering the cigarette case and maintain a dry environment inside the cigarette case. The water-absorbing layer 24 can be made of materials with strong water absorption, such as water-absorbing resin, high-water-absorbing fiber paper, etc., to ensure that the cigarettes do not get damp and deteriorate.

[0026] It should be noted that the specific model specifications need to be selected and determined according to the actual specifications of the device, etc. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated in detail.

[0027] The above is only the preferred implementation mode of the present invention and is not used to limit the present invention. For those skilled in the art, various changes and modifications can be made to the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
