A dynamic tactile micro-embossed tipping paper

Abstract

This invention specifically relates to a dynamically tactile micro-embossed tipping paper, comprising a base paper layer. The key feature is that a waterproof layer, a sponge layer, a breathable membrane, and a micro-embossed layer are sequentially layered and laminated on the base paper layer. The outer surface of the micro-embossed layer has evenly spaced intaglio grooves, which are tightly adhered to the sponge layer. The core of this invention is that when the lip is pressed, the compression deformation of the sponge layer directly forces the sidewalls of the intaglio grooves on the micro-embossed layer to rotate, thereby dynamically changing the width of the groove opening. This unique structural design creates an intelligent tactile sensation that changes with the pressure applied, significantly enhancing the richness and novelty of the tactile experience. Simultaneously, the intaglio grooves and their dynamic changes also enhance the breathability of the tipping paper, aiding in ventilation and reducing scorching, achieving a simultaneous improvement in tactile feel and user comfort.

Description

Technical Field

[0001] This utility model relates to the field of splicing paper technology, specifically a splicing paper with dynamic tactile micro-embossing. Background Technology

[0002] Tipping paper is the paper used to wrap around the filter rod and connect it to the cigarette pack. As an important component of the cigarette's appearance, tipping paper directly affects the consumer's overall perception of the cigarette and plays a crucial role in improving the cigarette's appearance quality. To enhance the appearance quality of cigarettes, printing processes such as hot stamping, transfer printing, and direct plating are generally used. However, these lack a three-dimensional and vivid visual effect. Therefore, embossing techniques have emerged to improve the quality and grade of the product packaging, giving the tipping paper a unique appearance and creating a new visual effect, while also increasing the product's added value.

[0003] In the prior art, Chinese patent application number 202320852405.2 describes a novel environmentally friendly refill paper with improved tactile feel. It includes a sponge strip and a deformable recessed layer assembly. A gap groove is provided between adjacent upper and lower sponge strips. Covering layers are provided on the upper and lower sides of each sponge strip. A cotton core is evenly spaced at each sponge strip. A deformable recessed layer assembly is provided between adjacent left and right cotton cores. The deformable recessed layer assembly includes several deformable composite components, each comprising an aluminum foil sheet and a fiber sheet. The aluminum foil sheet is sandwiched between two fiber sheets. A waterproof layer is provided on both the upper and lower surfaces of the refill paper. The deformable recessed layer assembly of this patent can be compressed from a three-dimensional supported state into a recessed state, making the cotton core of the sponge strip convex. However, the macroscopic deformation of the sponge is linear and smooth, deforming simultaneously with the acetate fiber rod inside the filter tip, and does not provide a direct and distinct tactile experience. Utility Model Content

[0004] The purpose of this invention is to provide a dynamic tactile micro-embossing splicing paper to solve the problems mentioned in the background art.

[0005] The technical solution of this utility model is: a micro-embossed tipping paper with dynamic tactile feedback, comprising a tipping paper base paper layer, wherein a waterproof layer, a sponge layer, a breathable membrane and a micro-embossing layer are sequentially stacked on the upper surface of the tipping paper base paper layer; wherein, the outer surface of the micro-embossing layer has equally spaced intaglio grooves, and the micro-embossing layer is attached to the sponge layer, so that the tactile feedback of the intaglio grooves can dynamically change with the deformation of the sponge layer.

[0006] Preferably, the sponge layer is pressed with corrugated grooves, which provide structural space for the compression deformation of the sponge layer.

[0007] Preferably, the intaglio grooves are evenly spaced around the circumference of the cigarette.

[0008] Preferably, the intaglio grooves are evenly spaced along the axial direction of the cigarette.

[0009] Preferably, the intaglio grooves are square and are uniformly distributed in a matrix on the surface of the microimprint layer.

[0010] Preferably, the surface of the corrugated groove is a smooth surface and is arranged around the circumference of the cigarette.

[0011] This utility model provides an improved version of a splicing paper with dynamic tactile micro-imprinting, which has the following improvements and advantages compared with the prior art: Firstly, this invention transforms the vertical compression deformation of the sponge layer into a structural deformation of the micro-imprint groove through physical coupling. When the lips press, the deformation of the sponge layer forces the sidewalls of the groove to rotate slightly, resulting in a controllable expansion or contraction of the groove width. This real-time, dynamic change in groove width allows the lip skin to experience continuously changing contact stress and friction coefficient, creating an actively adaptive and dynamically responsive intelligent tactile sensation that completely surpasses the single tactile experience of traditional static textures. Secondly, the intaglio groove structure of this invention itself constitutes a microscopic ventilation channel. The dynamic variation in its width further optimizes this function: during smoking, the presence of the groove increases the turbulent mixing effect between the smoke and the outside air, effectively diluting the mainstream smoke and reducing the amount of tar and nicotine inhaled per unit time. Simultaneously, the enhanced airflow also brings a better cooling effect, reducing the irritation of the oral cavity caused by hot smoke, thus improving the user experience from both health and sensory comfort perspectives.

[0013] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0014] This utility model provides an improved version of a micro-embossed splicing paper with dynamic tactile feedback. The technical solution of this utility model is as follows: like Figures 1-2 As shown, a type of micro-embossed tipping paper with dynamic tactile feedback is provided. Structurally, the tipping paper uses a base paper layer 1 as a base support. On its upper surface, a waterproof layer 7, a sponge layer 4, a breathable membrane 6, and a micro-embossed layer 2 are sequentially stacked. The micro-embossed layer 2 is constructed as equally spaced intaglio grooves 3. When the sponge layer 4 is compressed in the thickness direction, its deformation directly and without buffering acts on the micro-embossed layer 2 above, forcing the flexible intaglio grooves 3 to undergo elastic changes in their geometric shape, thereby achieving a dynamic tactile response.

[0015] Furthermore, corrugated grooves 5 are pre-pressed onto the body structure of the sponge layer 4. These recessed groove structures form regular weak points inside the sponge layer. Their core structural function is that when the sponge layer 4 is subjected to vertical pressure, its material preferentially bends and fills the cavities of these corrugated grooves 5 in a regular manner. This structure guides the potentially disordered, isotropic compression deformation into a directional, predictable, and regular deformation distributed along the grooves, thus providing a stable and consistent direction for the deformation of the upper micro-imprint layer 2.

[0016] The macroscopic distribution structure of the intaglio groove 3 is a continuous annular groove surrounding the circumference of the cigarette. This annular structural layout ensures that the user's lips have a continuous and consistent tactile experience when in contact with the tipping paper at any circumferential angle, thus providing a uniform and dynamic tactile feel.

[0017] The macroscopic distribution structure of the intaglio groove 3 is as follows: parallel straight grooves extending along the axial direction of the cigarette. This groove structure allows the user's lips to feel the directional guiding friction and its dynamic changes provided by the continuous groove edges as the user moves along the axial direction of the cigarette.

[0018] The micro-geometry of the intaglio groove 3 is as follows: square pits. These square pits are uniformly arranged in a horizontal and vertical matrix structure on the surface of the microimprint layer 2. Each square pit has four mutually perpendicular sidewalls. This structure allows the sidewalls of each pit to generate coordinated and symmetrical rotation and displacement under stress and deformation, thereby producing a unique grid-like dynamic tactile feel brought about by the change of dense dots.

[0019] Furthermore, the corrugated groove 5 is characterized by its smooth surface. This low-friction inner surface structure ensures that the movement resistance of the sponge layer within the groove wall is minimized during compression deformation, allowing deformation energy to be used to drive overall structural changes with almost no loss. Simultaneously, these corrugated grooves 5 also form a wave-shaped annular structure surrounding the cigarette, together with the functional layer above, creating a concentric circular deformation control system that works synergistically from the inside out.

[0020] Working principle: When pressure is applied to the lip of the packaging paper, the pressure is transmitted through the micro-imprint layer to the underlying sponge layer, causing it to undergo synergistic deformation of vertical compression and lateral expansion. This deformation is strongly coupled to the micro-imprint layer through the intermediate breathable membrane, forcing the sidewalls of the intaglio printing groove to undergo minute elastic rotation. This rotation directly causes a dynamic change in the geometric width of the groove opening, thereby altering the contact area and frictional stress with the lip skin in real time, producing a unique and perceptible dynamic tactile sensation.

[0021] At the same time, the intaglio groove itself, as a micro ventilation channel, also regulates the local airflow to a certain extent through dynamic changes in its width, which works in synergy with the smoking process and plays an auxiliary role in ventilation and tar reduction.

[0022] The foregoing description enables those skilled in the art to implement or use this invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this invention. Therefore, this invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
