Description

Technical Field

[0001] This invention relates to the field of label manufacturing technology, and in particular to a printable wrap-around cigar traceability label. Background Technology

[0002] Most cigars currently use traditional paper labels, whole-box labels, or fully adhesive labels. Conventional labels lack a segmented structure, and the overall adhesive coverage makes them prone to sticking together, preventing them from being pre-printed with laser or inkjet printers. Furthermore, conventional labels lack localized, controllable adhesive, making it difficult to secure them after wrapping around a single cigar. Misalignment is common during application, and residual adhesive can easily contaminate the cigar wrapper.

[0003] Standard labels lack a standardized QR code area, making them unsuitable for the digital needs of individual cigar cylinder entry and exit, inventory counting, and traceability management. Standard label sizes do not match the cylindrical shape of individual cigar cylinders, resulting in poor adhesion when wrapped, inconvenient installation and removal, and the inability to be repeatedly and neatly bound.

[0004] Meanwhile, when regular labels enter the printing equipment, if there are cuts on the surface of the regular label, the regular label surface lacks a constraint mechanism to keep the cut edges coplanar. The cut edges are prone to detach from the two-dimensional plane and produce a raised structure. The cut edges are also prone to hooking onto the path of mechanical parts inside the printing equipment, causing the regular label to stop inside the printing equipment and cause paper jams.

[0005] When a standard label is wrapped around a single cigar shaft, the radial expansion of the cigar shaft generates outward tension. Due to the simple stress structure of the standard label, the joints are prone to vertical peeling stress, causing delamination. Furthermore, when the standard label is subjected to circumferential tensile stress generated by the outward expansion of the cigar shaft, this stress tends to concentrate at the right-angle intersections within the label, creating stress concentration points. This can cause the label fibers to break and tear, compromising the overall structural integrity of the label.

[0006] Therefore, this invention proposes a printable wrap-around cigar traceability label to address the shortcomings of existing technologies. Summary of the Invention

[0008] The purpose of this invention is to provide a printable wrap-around cigar traceability label, which solves the problem that conventional labels are prone to peeling and delamination when the single cigar expands due to the single stress structure after wrapping around a single cigar. It also solves the problem that tensile stress is concentrated at the right-angle intersection structure inside the conventional label, causing the conventional label fibers to break and tear.

[0009] To achieve the above objectives, the present invention provides the following technical solution:

[0010] This invention provides a printable wrap-around cigar traceability label, comprising a flexible paper label substrate, which is divided along its length into a left adhesive area and a right printing display area. An adhesive layer is laminated to the back of the left adhesive area, and a release protective layer is adhered to the outside of the adhesive layer.

[0011] The free edge of the left adhesive area tapers inward to form a gradually intersecting guide end. The two edges of the left adhesive area near the boundary with the right printing display area bulge outward to form lateral anti-retraction latching wings. An intersecting positioning bend line is provided at the boundary between the left adhesive area and the right printing display area, and a non-adhesive isolation strip is provided at the corresponding position of the intersecting positioning bend line on the self-adhesive layer. An I-shaped slit is formed throughout the right printing display area, consisting of a horizontal main slit and a vertical secondary slit intersecting perpendicularly.

[0012] After the lateral anti-reverse clamping wing bends inward and passes through the transverse main cut, it returns to a flat and unfolded state. The lateral anti-reverse clamping wing then gets stuck inside the vertical secondary cut, and the lateral anti-reverse clamping wing and the I-shaped cut form a one-way mechanical locking interference.

[0013] The printable wrap-around cigar traceability label includes stress-relief holes, which are formed at both ends of the vertical secondary cut. These stress-relief holes are circular through-holes with smooth, rounded edges. They connect to the apex of the vertical secondary cut, replacing the right-angle intersection of the apex with a rounded structure.

[0014] The stress-relieving crack-stopping hole receives the tensile stress transmitted to the end of the I-shaped cut. The arc structure disperses the tensile stress circumferentially along the edge of the stress-relieving crack-stopping hole, eliminating the stress concentration source at the apex of the vertical secondary cut end and preventing fiber breakage and tearing of the flexible paper label substrate along the apex of the vertical secondary cut end.

[0015] The printable wrap-around cigar traceability label includes micro-connecting points, which are collinearly spaced inside the main horizontal cut and the secondary vertical cut. These micro-connecting points do not completely sever the fibers of the flexible paper label substrate; instead, they connect the two edges of the main horizontal cut and the two edges of the secondary vertical cut.

[0016] The micro-connector possesses an initial shear resistance threshold, which is greater than the tangential frictional force applied to the right-side printing display area surface by the paper feed mechanism of the printing device. The micro-connector resists the pulling force of the tangential frictional force, maintaining the I-shaped slit in a closed plane state. The gradually interlacing guide end presses into the I-shaped slit, applying a vertical thrust exceeding the compressive fracture threshold of the micro-connector. Uncut fibers inside the micro-connector undergo shear fracture and separation, transforming the I-shaped slit into a through-open state.

[0017] A mechanical interference fit is established between the left bonding area and the right printing display area. The lateral anti-rejection latching wing has a total lateral width, and the main lateral cut has a lateral opening width. The total lateral width of the lateral anti-rejection latching wing is greater than the lateral opening width of the main lateral cut. Two vertical secondary cuts are located at both ends of the main lateral cut, with a maximum lateral spacing between their outer edges. The total lateral width of the lateral anti-rejection latching wing is less than the maximum lateral spacing between the two vertical secondary cuts.

[0018] After the lateral anti-retraction clip wing penetrates the transverse main cut, it breaks free from the diameter restriction of the transverse main cut. The internal stress of the lateral anti-retraction clip wing is released and it returns to the unfolded state. The two ends of the lateral anti-retraction clip wing are respectively embedded into the corresponding vertical secondary cut and stress release crack arrest hole on one side, establishing a one-way mechanical locking state.

[0019] The adhesive-free insulating tape covers the bending area of ​​the interlacing positioning bend line. Positioned at the apex of the bend, the tape maintains a chemical adhesive-free distribution in this area. It provides an adhesive-free isolation space, preventing the adhesive layer from being squeezed inwards during stepped bending deformation when the left-side adhesive area extends through the I-beam cut, thus preventing the adhesive layer from overflowing due to compression. The interlacing positioning bend line is positioned by a unidirectional mechanical locking interference structure, aligning parallel to the I-beam cut, achieving self-centering parallel circumferential positioning for a single cigar shaft.

[0020] The release protective layer remains attached to the outside of the self-adhesive layer, and the release protective layer is bonded to the left adhesive area to form a composite structure layer. The left adhesive area, the self-adhesive layer and the release protective layer are superimposed to form a multi-layered structure, which increases the local cross-sectional thickness of the flexible paper label substrate.

[0021] The composite structural layer provides longitudinal compressive stiffness support parallel to the penetration direction. The longitudinal compressive stiffness support resists the bending moment generated by the penetration thrust, prevents buckling and folding deformation of the left bonding area when subjected to the penetration thrust, and maintains the straight penetration posture of the left bonding area.

[0022] The left bonding area tapers inward along its width from the edge furthest from the right printing display area, forming a gradient-interlacing guide end. The lateral dimension of this guide end decreases outward, reducing its width and guiding the left bonding area into the main lateral cut. The guide end is vertically aligned with the I-shaped cut from the inside of the right printing display area, allowing the left bonding area to pass through the main lateral cut and exit outward from the right printing display area. The front of the left bonding area is designated as a pre-printed area for a QR code, while the front of the right printing display area is designated as a text data printing area.

[0023] The back of the right-side printing display area is not covered by an adhesive layer, and both the back and front of the right-side printing display area have a flat structure. The surface of the flexible paper label substrate has an ink-absorbing coating, providing a surface for ink adhesion. Both the left and right edges of the flexible paper label substrate have rounded corners to prevent sharp edges from contacting the individual cigar stick.

[0024] Peel off the release liner to expose the adhesive layer on the back of the left adhesive area. Flatten and adhere the left adhesive area along the interlacing positioning bend line, then press the left adhesive area against the front of the right printed display area using the adhesive layer. The lateral anti-retraction latching wing and the I-beam cut create a one-way mechanical locking structure, which, together with the adhesive layer, establishes a double anchoring state after the flexible paper label substrate surrounds and covers the single cigar column.

[0025] The double anchoring eliminates the spatial freedom of relative displacement of the left adhesive area along the direction parallel or perpendicular to the surface of the flexible paper label substrate, forming a double-layer interlocking mechanical label sleeve structure on the outside of a single cigar column.

[0026] When a single cigar column expands radially, generating outward tension, this tension is transferred to the junction of the interlacing positioning bend and the I-shaped cut. The radial compressive force exerted by the outer wall of the single cigar column on the flexible paper label substrate is converted into circumferential tensile stress along the length of the flexible paper label substrate. The interlacing positioning bend, in conjunction with a unidirectional mechanical locking interference structure, converts the vertical peeling stress generated by the outward expansion of the single cigar column into shear stress parallel to the surface of the adhesive layer.

[0027] The spatial interference blocking surface formed by the lateral anti-retraction snap-fit ​​wing and the edge of the I-shaped cut intercepts circumferential tensile stress. The shear strength of the self-adhesive layer against shear stress is greater than its peel strength against peel stress. The mechanical blocking force provided by the spatial interference blocking surface, combined with the adhesive shear force provided by the self-adhesive layer, jointly offsets the circumferential tensile stress, preventing delamination between the left adhesive area and the right printed display area, establishing a stress orthogonal transformation closed loop, and maintaining the stability of the ring-shaped fixed label structure.

[0028] In summary, the present invention has at least one of the following beneficial technical effects:

[0029] 1. This invention utilizes a lateral anti-retraction snap-fit ​​wing formed by the outward protrusion of the left adhesive area edge. This lateral anti-retraction snap-fit ​​wing passes through the transverse main cut and engages with the vertical secondary cut, forming a one-way mechanical locking interference. This one-way mechanical locking interference, combined with the adhesive layer, establishes a double anchoring state. When a single cigar column undergoes radial expansion, generating outward tension, the interlaced positioning bending line, in conjunction with the one-way mechanical locking interference structure, converts the vertical peeling stress into shear stress parallel to the adhesive layer surface. The mechanical blocking force, combined with the adhesive shear force, counteracts the circumferential tensile stress, preventing peeling and delamination between the left adhesive area and the right printed display area, thus maintaining the stability of the ring-shaped fixed label structure.

[0030] 2. This invention utilizes micro-connection points distributed collinearly at intervals within the main horizontal cut and the secondary vertical cut. The initial shear resistance threshold of these micro-connection points is greater than the tangential frictional force applied to the right-side printing display area surface by the paper feeding mechanism of the printing equipment. These micro-connection points resist the pulling force of the tangential frictional force, maintaining the I-shaped cut in a closed plane state, preventing the edges of the I-shaped cut from detaching from the two-dimensional plane and creating a warped structure. This also blocks the path of the I-shaped cut edges connecting to the internal mechanical parts of the printing equipment, eliminating paper jams caused by the flexible paper label substrate stagnating inside the printing equipment, and ensuring smooth printing of text and images.

[0031] 3. This invention utilizes stress-relieving and crack-preventing holes, which are circular through-holes with smooth, rounded edges, to create a through-hole structure at both ends of the vertical secondary cut. These stress-relieving and crack-preventing holes replace the right-angle intersection structure at the apex of the vertical secondary cut with a rounded structure. The rounded structure disperses the tensile stress transmitted to the end of the I-shaped cut circumferentially along the edge of the stress-relieving and crack-preventing hole, eliminating the stress concentration source at the apex of the vertical secondary cut and preventing fiber breakage and tearing of the flexible paper label substrate along the apex of the vertical secondary cut, thus maintaining the overall structural integrity of the flexible paper label substrate.

[0036] The following is in conjunction with the appendix Figure 1 - Appendix Figure 3 The present invention will be further described in detail below.

[0037] See attached document Figures 1 to 3 This invention provides a printable wrap-around cigar traceability label. The printable wrap-around cigar traceability label provides a flexible paper label substrate 1. The flexible paper label substrate 1 is divided into a left adhesive area 2 and a right printing display area 3 along its length. A self-adhesive layer 4 is laminated on the back of the left adhesive area 2. A release protective layer 5 is attached and covered on the outside of the self-adhesive layer 4. The free edge of the left adhesive area 2 tapers inward to form a gradually interlacing guide end 6. The two edges of the left adhesive area 2 near the junction with the right printing display area 3 protrude outward to form lateral anti-retraction snap wings 7.

[0038] An interlacing positioning bending line 8 is set at the junction of the left adhesive area 2 and the right printing display area 3. An adhesive-free isolation strip 9 is set at the corresponding position of the non-adhesive layer 4 at the interlacing positioning bending line 8. The front of the left adhesive area 2 is set as a reserved printing area for QR codes.

[0039] The right-side printing display area 3 is set as a text data printing area on the front. The back of the right-side printing display area 3 is not glued. The right-side printing display area 3 has a through-cut I-shaped slit 10. The I-shaped slit 10 is formed by the perpendicular intersection of the horizontal main slit 11 and the vertical secondary slit 12. Micro-connection points 13 are distributed collinearly and at intervals inside the horizontal main slit 11 and the vertical secondary slit 12. Stress relief crack-stopping holes 14 are opened through both ends of the vertical secondary slit 12.

[0040] Micro-connection point 13 connects to the edge of the I-shaped cut 10, maintaining the right printing display area 3 in a closed plane state as it enters the paper feeding mechanism of the printing device, preventing the edge of the I-shaped cut 10 from lifting up and hooking into the internal structure of the printing device. The printing device prints the QR code in the reserved printing area and prints the text data in the text data printing area.

[0041] The flexible paper label substrate 1 is bent and wraps around the outer wall of a single cigar column. The release protective layer 5 remains attached to the outside of the self-adhesive layer 4. The release protective layer 5 and the flexible paper label substrate 1 are bonded together to form a composite structure layer. The composite structure layer provides longitudinal compressive stiffness support to prevent buckling deformation of the left adhesive area 2 under pressure. The gradually interlaced guide end 6 is stressed and breaks the micro-connection point 13, opening the I-shaped slit 10. The left adhesive area 2 passes through the transverse main slit 11. The lateral anti-retraction latching wing 7 bends inward and deforms after passing through the transverse main slit 11, then returns to a flat and unfolded state, locking into the vertical secondary slit 12 and the stress release crack-stopping hole 14. The lateral anti-retraction latching wing 7 and the I-shaped slit 10 form a one-way mechanical locking interference. The interlaced positioning bending line 8 is positioned by the one-way mechanical locking interference structure, parallel to the I-shaped slit 10, completing the self-centering parallel wrap around the single cigar column.

[0042] Peel off the release liner 5 to expose the adhesive layer 4. Smoothly flatten the left adhesive area 2 along the interlacing positioning bend line 8. The adhesive-free release strip 9 maintains the absence of chemical adhesive at the bend apex of the interlacing positioning bend line 8, preventing the adhesive from undergoing rheological changes due to compression when the left adhesive area 2 extends through the I-shaped cut 10 and experiences stepped bending deformation. Press and fix the adhesive layer 4 to the outer surface of the right-side printing display area 3.

[0043] The flexible paper label substrate 1 forms a double-layer interlocking mechanical sleeve label structure on the outside of a single cigar column. When the single cigar column expands radially, generating outward tension, the tension is transmitted to the junction of the interlocking positioning bending line 8 and the I-shaped cut 10. The interlocking positioning bending line 8, in conjunction with the unidirectional mechanical locking interference structure, converts the vertical peeling stress generated by the outward expansion of the single cigar column into shear stress parallel to the surface of the adhesive layer 4. The stress-relieving crack-preventing hole 14 disperses the concentrated tensile stress at the end of the I-shaped cut 10 into circumferential tensile stress distributed around the edge of the hole wall, preventing cracks from propagating inside the flexible paper label substrate 1 and maintaining the stability of the annular fixed sleeve label structure.

[0044] Printable wrap-around cigar traceability labels establish spatial relative position benchmarks and three-dimensional orientation references.

[0045] The flexible paper label substrate 1 is laid flat. The direction parallel to the longest side of the flexible paper label substrate 1 is defined as the length direction, and the direction perpendicular to the length direction and parallel to the paper surface is defined as the width direction. Left and right sides are defined at both ends along the length direction. The left side corresponds to the left adhesive area 2, and the right side corresponds to the right printing display area 3. Geometric dimensions parallel to the length direction are defined as longitudinal dimensions, and geometric dimensions parallel to the width direction are defined as transverse dimensions. The transverse main cut 11 extends parallel to the width direction, and the vertical secondary cut 12 extends parallel to the length direction.

[0046] Along a direction perpendicular to the plane of the flexible paper label substrate 1, the surface used for printing graphic information is defined as the front side, and the surface opposite the front side and away from the printed graphic information is defined as the back side. The front side has a reserved printing area for a QR code and a text data printing area. The back side has an adhesive layer 4.

[0047] Along the width direction, the direction of movement toward the central axis of symmetry of the flexible paper label substrate 1 is defined as inward, and the direction of movement away from the central axis of symmetry of the flexible paper label substrate 1 is defined as outward. The free end edge of the left adhesive area 2 contracts inward to form a gradually interlacing guide end 6, reducing the lateral interlacing width and guiding the left adhesive area 2 into the lateral main cut 11. The two sides of the left adhesive area 2 near the interlacing positioning bending line 8 protrude outward to form lateral anti-reverse locking wings 7, increasing the lateral interference width and establishing a unidirectional locking structure after interlacing.

[0048] The flexible paper label substrate 1 is bent and wraps around the outer wall of a single cigar column to form a ring structure. After the ring structure is established, the spatial direction facing and adhering to the outer wall of the single cigar column is defined as the inner side, and the spatial direction facing away from the outer wall of the single cigar column and towards the environment is defined as the outer side. The left adhesive area 2 is vertically inserted into the transverse main cut 11 from the inner side of the right printing display area 3, and then extends outward from the outer side of the right printing display area 3. The left adhesive area 2, through the inner-to-outer insertion action, changes the overlapping position relationship of the two ends of the flexible paper label substrate 1, establishing a multi-layered spatial interlocking state.

[0049] See attached document Figures 1 to 3 A printable wrap-around cigar traceability label is provided using a flexible paper label substrate 1. The flexible paper label substrate 1 has a long, strip-shaped structure. The overall length of the flexible paper label substrate 1 is set between 80mm and 120mm, and the overall width is set between 20mm and 30mm. The flexible paper label substrate 1 is made of high-white writing paper or coated paper. The weight of the flexible paper label substrate 1 is set between 60g and 100g. An ink-absorbing coating is applied to the surface of the flexible paper label substrate 1. This ink-absorbing coating provides a surface for ink adhesion, meeting the needs of inkjet and laser printing equipment for graphic printing. The left and right edges of the flexible paper label substrate 1 are rounded. The rounded corners prevent sharp edges from contacting the individual cigar shaft, preventing scratches on the surface of the individual cigar shaft during wrapping operations.

[0050] The flexible paper label substrate 1 is divided along its length into a left bonding area 2 and a right printing display area 3. The length of the left bonding area 2 is set to be between 10mm and 20mm, and its width is set to be between 15mm and 25mm. A 2mm gap is left between the left edge of the left bonding area 2 and the leftmost outer edge of the flexible paper label substrate 1. The right edge of the left bonding area 2 connects to the left edge of the right printing display area 3. The right printing display area 3 occupies the remaining length of the flexible paper label substrate 1. The right printing display area 3 provides a flat surface to prevent jamming of the printing equipment's paper feed mechanism.

[0051] See attached document Figures 1 to 3 A self-adhesive layer 4 is provided on the back of the left adhesive area 2. A release protective layer 5 is attached to the side of the self-adhesive layer 4 away from the left adhesive area 2. The release protective layer 5 covers the surface of the self-adhesive layer 4, isolating it from contact with the external environment. The edge of the left adhesive area 2 away from the right printing display area 3 tapers inward along its width, forming a gradient interlacing guide end 6. The lateral dimension of the gradient interlacing guide end 6 decreases outward, reducing the width of the interlacing end and guiding the left adhesive area 2 through the lateral main cut 11.

[0052] The left bonding area 2, near the junction with the right printing display area 3, has its two edges protruding outwards along its width, forming lateral anti-retraction latching wings 7. The lateral dimension of the lateral anti-retraction latching wings 7 is larger than the lateral dimension of the regular area of ​​the left bonding area 2. The lateral anti-retraction latching wings 7 provide a spatial interference blocking surface, preventing the left bonding area 2 from retracting along the insertion path from the lateral main cut 11. At the junction of the left bonding area 2 and the right printing display area 3, an interlacing positioning bending line 8 is formed through a die-cutting and creasing process.

[0053] The interlacing positioning bend line 8 extends in a straight line along the width direction. The adhesive layer 4 is left open along the extension direction of the interlacing positioning bend line 8, forming a non-adhesive release strip 9. The width of the non-adhesive release strip 9 is set to be between 1 mm and 2 mm. The non-adhesive release strip 9 covers the bending area of ​​the interlacing positioning bend line 8. The non-adhesive release strip 9 maintains a non-adhesive distribution at the bend apex of the interlacing positioning bend line 8, preventing the adhesive in the left adhesive area 2 from being squeezed out during the bending operation along the interlacing positioning bend line 8, which could cause the adhesive to overflow due to rheological changes.

[0054] See attached document Figures 1 to 3 The right-side printing display area 3 has no adhesive layer 4 covering its back, and both the back and front of the right-side printing display area 3 are flat. An I-shaped slit 10 runs through the interior of the right-side printing display area 3. The I-shaped slit 10 consists of a horizontal main slit 11 and two vertical secondary slits 12. The horizontal main slit 11 extends along the width direction. The two vertical secondary slits 12 extend parallel along the length direction. The two ends of the horizontal main slit 11 are perpendicularly connected to the center points of the two vertical secondary slits 12.

[0055] Micro-connection points 13 are collinearly spaced within the main transverse cut 11 and the two vertical secondary cuts 12. These micro-connection points 13 do not completely sever the fibers of the flexible paper label substrate 1. They connect the edges of the main transverse cut 11 to the edges of the two vertical secondary cuts 12. The connecting force of the micro-connection points 13 maintains the I-shaped cut 10 in a closed plane state. This closed plane state keeps the surface of the right-side printing display area 3 flat and continuous, preventing edge lifting due to cutting separation and avoiding paper jams when the right-side printing display area 3 passes through the paper feeding mechanism of the printing equipment.

[0056] Stress-relieving and crack-preventing holes 14 are provided at both ends of the two vertical secondary cuts 12. There are a total of four ends to the two vertical secondary cuts 12, with four stress-relieving and crack-preventing holes 14 corresponding to each end. The stress-relieving and crack-preventing holes 14 are circular through-holes with smooth, rounded edges. The stress-relieving and crack-preventing holes 14 connect to the apex of the vertical secondary cuts 12. The stress-relieving and crack-preventing holes 14 replace the right-angle intersection structure of the apex of the vertical secondary cuts 12 with a rounded structure. The stress-relieving and crack-preventing holes 14 receive the tensile stress transmitted to the end of the I-shaped cut 10. The rounded structure disperses the tensile stress circumferentially along the edge of the stress-relieving and crack-preventing holes 14, eliminating the stress concentration source at the apex of the vertical secondary cuts 12 and preventing fiber breakage and tearing of the flexible paper label substrate 1 along the apex of the vertical secondary cuts 12.

[0057] See attached document Figures 1 to 3 A mechanical interference fit is established between the left bonding area 2 and the right printing display area 3. The lateral anti-recoil latching wing 7 has a total lateral width dimension. The lateral main cut 11 has a lateral opening width dimension. The total lateral width dimension of the lateral anti-recoil latching wing 7 is greater than the lateral opening width dimension of the lateral main cut 11. The dimensional difference forces the lateral anti-recoil latching wing 7 to bend inward at both ends when it passes through the lateral main cut 11. Two vertical secondary cuts 12 are distributed at both ends of the lateral main cut 11, and the outer edges of the two vertical secondary cuts 12 have the maximum lateral spacing dimension.

[0058] The total lateral width of the lateral anti-recoil latching wing 7 is less than the maximum lateral spacing between the two vertical secondary cuts 12. After penetrating the main lateral cut 11, the lateral anti-recoil latching wing 7 is released from the diameter limitation of the main lateral cut 11. The internal stress of the lateral anti-recoil latching wing 7 is released, and the lateral anti-recoil latching wing 7 returns to its unfolded state. The two ends of the lateral anti-recoil latching wing 7 are respectively embedded in the corresponding vertical secondary cut 12 and stress relief crack-stopping hole 14. The total lateral width of the lateral anti-recoil latching wing 7 is greater than the lateral opening width of the main lateral cut 11. The lateral anti-recoil latching wing 7 forms a blocking surface to prevent the left bonding area 2 from exiting the main lateral cut 11 along the original insertion path, establishing a one-way mechanical locking state.

[0059] See attached document Figures 1 to 3 Uncut fibers are partially preserved inside the transverse main incision 11 and the two vertical secondary incisions 12 to form micro-connection points 13. The width of the micro-connection points 13 along the incision extension direction is set to be in the range of 0.3 mm to 0.5 mm. The structural parameters of the micro-connection points 13 are established to determine the shear resistance and compressive fracture threshold.

[0060] When the paper feeding mechanism of the printing device contacts the surface of the right printing display area 3, the paper feeding mechanism generates a tangential frictional force parallel to the surface of the flexible paper label substrate 1. The shear resistance of the micro-connection point 13 is greater than the tangential frictional force. The micro-connection point 13 resists the pulling force of the tangential frictional force, maintains the two-dimensional planar state of the right printing display area 3, and prevents the edge of the transverse main cut 11 and the edges of the two vertical secondary cuts 12 from detaching from the two-dimensional plane and curling up.

[0061] When the gradient-interlacing guide end 6 is perpendicularly attached to and presses against the I-shaped cut 10, the gradient-interlacing guide end 6 applies a pushing force perpendicular to the surface of the flexible paper label substrate 1. The compressive fracture threshold of the micro-connection point 13 is less than the pushing force. When the pushing force overcomes the compressive fracture threshold, the uncut fibers inside the micro-connection point 13 undergo shear fracture separation. The fracture of the micro-connection point 13 releases the closure constraint between the edge of the transverse main cut 11 and the edges of the two vertical secondary cuts 12. The I-shaped cut 10 transforms into a through-open state, providing an interlacing channel for the left adhesive area 2.

[0062] See attached document Figures 1 to 3 The flexible paper label substrate 1 is fed into the paper feeding mechanism of the printing equipment. The rollers of the paper feeding mechanism contact the surface of the right-side printing display area 3, generating tangential friction. The micro-connection point 13 withstands the tangential friction pull, maintaining the coplanarity of the edge of the transverse main cut 11 and the edges of the two vertical secondary cuts 12. This coplanarity maintains the flatness and continuity of the right-side printing display area 3 surface, preventing the edges of the transverse main cut 11 and the two vertical secondary cuts 12 from detaching from the two-dimensional plane and creating a warped structure. The flat, continuity-free surface blocks the path of the right-side printing display area 3 to the internal mechanical parts of the printing equipment, eliminating paper jams caused by the flexible paper label substrate 1 stagnating inside the printing equipment. The print head of the printing equipment moves above the reserved printing area for the QR code on the front of the left adhesive area 2 and sprays ink to form a QR code pattern. The print head of the printing equipment moves above the text data printing area on the front of the right-side printing display area 3 and sprays ink to form text data.

[0063] See attached document Figures 1 to 3The flexible paper label substrate 1 bends, forming a wraparound shape around the outer wall of the single cigar column, with a pre-reserved operating gap between the left adhesive area 2 and the right printing display area 3. The release protective layer 5 remains attached to the outside of the self-adhesive layer 4. The release protective layer 5 and the left adhesive area 2 are bonded together to form a composite structural layer. The composite structural layer increases the cross-sectional thickness, providing longitudinal compressive stiffness support parallel to the insertion direction. The longitudinal compressive stiffness support resists the bending moment generated by the insertion thrust, preventing the left adhesive area 2 from buckling and folding deformation when subjected to the insertion thrust, maintaining the straight insertion posture of the left adhesive area 2, and solving the problem of single-layer paper collapsing under pressure and being unable to insert through narrow gaps.

[0064] The gradient-interlacing guide end 6 is vertically aligned with the I-shaped cut 10 from the inside of the right-side printing display area 3. The gradient-interlacing guide end 6 presses into the I-shaped cut 10, applying a vertical thrust to the micro-connection point 13. The vertical thrust exceeds the pressure fracture threshold of the uncut fibers remaining inside the micro-connection point 13, causing shear fracture separation. The fracture of the micro-connection point 13 releases the closure constraint between the edge of the transverse main cut 11 and the edges of the two vertical secondary cuts 12. The I-shaped cut 10 transforms into a through-open state. The gradient-interlacing guide end 6 guides the left-side bonding area 2 through the transverse main cut 11. The left-side bonding area 2 then extends outward from the right-side printing display area 3.

[0065] See attached document Figures 1 to 3 Pull the left bonding area 2 along the direction away from the right printing display area 3. The lateral anti-retraction latching wing 7 is blocked by the lateral opening width of the transverse main cut 11. The two ends of the lateral anti-retraction latching wing 7 are compressed and deformed inward. The lateral anti-retraction latching wing 7 enters and passes through the transverse main cut 11 in the inward bending deformation state. After the lateral anti-retraction latching wing 7 passes through the transverse main cut 11, the lateral anti-retraction latching wing 7 is released from the area limited by the lateral opening width of the transverse main cut 11. The bending stress inside the lateral anti-retraction latching wing 7 is released. The lateral anti-retraction latching wing 7 returns to its flat and unfolded state. The two ends of the lateral anti-retraction latching wing 7 respectively lock into the interior of the corresponding vertical secondary cut 12 and the stress release crack prevention hole 14. The outer edge contour of the lateral anti-retraction latching wing 7 and the edge contour of the I-shaped cut 10 form a spatial interference shield. The spatial interference shield establishes a one-way mechanical locking structure. A one-way mechanical locking structure blocks the movement trajectory of the left adhesive area 2, which exits in the opposite direction along the insertion path from the transverse main cut 11. The interlacing positioning bending line 8 is positioned by the one-way mechanical locking structure. The interlacing positioning bending line 8 is aligned parallel to the I-shaped cut 10. The two ends of the flexible paper label substrate 1 are self-centering and parallelly wrapped around the outer wall of the single cigar column. The self-centering parallel wrapping position prevents misalignment and oblique pulling when the flexible paper label substrate 1 wraps around the single cigar column. The two ends of the flexible paper label substrate 1 are tightened to eliminate spatial operation gaps, completing a tight wrap around the outer wall of the single cigar column.

[0066] See attached document Figures 1 to 3 Peel off the release liner 5 to expose the adhesive layer 4 on the back of the left adhesive area 2. The left adhesive area 2 is flattened and adhered along the interlacing positioning bend line 8. The adhesive-free isolation strip 9 is positioned at the bend apex of the interlacing positioning bend line 8. The adhesive-free isolation strip 9 maintains that there is no adhesive layer 4 distributed in the bend apex area of ​​the interlacing positioning bend line 8. The adhesive-free isolation strip 9 provides an adhesive-free isolation space to prevent the adhesive layer 4 from being squeezed inward when the left adhesive area 2 passes through the I-shaped cut 10 and undergoes a stepped bending deformation, thus preventing the adhesive layer 4 from overflowing due to compression.

[0067] The left adhesive area 2 is pressed and adhered to the front of the right printing display area 3 by the self-adhesive layer 4. The self-adhesive layer 4 bonds and fixes the left adhesive area 2 to the outer surface of the right printing display area 3. The lateral anti-retraction snap-fit ​​wing 7 and the I-shaped cut 10 together establish a one-way mechanical locking structure, which, together with the adhesive layer 4, establishes a double anchoring state after the flexible paper label substrate 1 surrounds and covers the single cigar column. The double anchoring state eliminates the spatial degree of freedom of the left adhesive area 2 to relative displacement along the direction parallel or perpendicular to the surface of the flexible paper label substrate 1.

[0068] See attached document Figures 1 to 3 The flexible paper label substrate 1, limited by its single-layer paper material, is prone to buckling and folding deformation when subjected to insertion thrust. A self-adhesive layer 4 and a release liner 5 are laminated on the back of the left adhesive area 2, forming a multi-layered structure. This multi-layered structure increases the local cross-sectional thickness of the flexible paper label substrate 1. This increased thickness provides longitudinal compressive stiffness parallel to the insertion direction. This longitudinal compressive stiffness resists the bending moment generated when the gradually changing insertion guide end 6 presses against the I-shaped cut 10, preventing buckling and folding deformation of the left adhesive area 2 during insertion, maintaining its straight insertion posture, and solving the problem of single-layer paper material collapsing under pressure and failing to complete the insertion action.

[0069] A I-shaped slit 10 is made on the surface of the right-side printing display area 3. The edges of the I-shaped slit 10 disrupt the continuous flatness of the surface of the right-side printing display area 3, and the edges of the I-shaped slit 10 are prone to curling and lifting when subjected to external friction. Micro-connection points 13 are set inside the I-shaped slit 10. The micro-connection points 13 connect the two sides of the I-shaped slit 10. The micro-connection points 13 have an initial shear resistance threshold. The initial shear resistance threshold is greater than the tangential friction force applied to the surface of the right-side printing display area 3 by the paper feeding mechanism of the printing equipment. The micro-connection points 13 resist the pulling of the tangential friction force and maintain the coplanarity of the two sides of the I-shaped slit 10. The coplanar state prevents the edges of the I-shaped slit 10 from detaching from the two-dimensional plane and forming a lifting structure, blocks the path of the edges of the I-shaped slit 10 to the internal mechanical parts of the printing equipment, and eliminates the failure of the flexible paper label substrate 1 to be obstructed in the operation of the printing equipment.

[0070] See attached document Figures 1 to 3 When a single cigar column undergoes radial expansion, the outer wall of the cigar column applies a radial compressive force outward to the flexible paper label substrate 1. This radial compressive force is converted into circumferential tensile stress along the length of the flexible paper label substrate 1. This circumferential tensile stress drives the left adhesive area 2 and the right printed display area 3 to move away from each other. The left adhesive area 2 passes through the I-shaped slit 10 and flattens outward along the interlacing positioning bending line 8. The left adhesive area 2 is bonded and fixed to the front of the right printed display area 3 by the self-adhesive layer 4, forming an interlaced flat load-bearing structure. When the circumferential tensile stress acts on the interlaced flat load-bearing structure, the spatial interference blocking surface formed by the lateral anti-retraction snap wing 7 and the edge of the I-shaped slit 10 intercepts the circumferential tensile stress. The spatial interference blocking surface converts the peeling stress of tearing the self-adhesive layer 4 along the normal direction on the flexible paper label substrate 1 into shear stress parallel to the surface of the self-adhesive layer 4. The shear strength of the self-adhesive layer 4 against shear stress is greater than its peel strength against peel stress. Shear stress is evenly distributed along the tangent of the adhesive surface of the self-adhesive layer 4, preventing stress concentration at the local edges of the intersecting positioning bending line 8. The mechanical blocking force provided by the spatial interference blocking surface, combined with the adhesive shear force provided by the self-adhesive layer 4, jointly counteracts the circumferential tensile stress, preventing peeling and delamination between the left adhesive area 2 and the right printing display area 3, establishing a stress orthogonal transformation closed loop, and maintaining the locked and stable state of the flexible paper label substrate 1 surrounding the single cigar column.

[0071] See attached document Figures 1 to 3 After the left bonding area 2 is inserted into the I-shaped cut 10 to establish a one-way mechanical locking state, the single cigar column undergoes radial expansion, generating circumferential tensile stress. The circumferential tensile stress drives the lateral anti-reverse locking wing 7 to press against the edges of the two vertical sub-cuts 12. The circumferential tensile stress is transmitted along the length of the vertical sub-cuts 12 to the apex of the end of the vertical sub-cuts 12.

[0072] Four stress-relief crack-preventing holes 14 are drilled through the four apex positions of the two vertical secondary cuts 12. The stress-relief crack-preventing holes 14 are circular through-holes with smooth, rounded edges. The stress-relief crack-preventing holes 14 replace the right-angle shear structure at the apex of the vertical secondary cuts 12. The smooth, rounded edges increase the local radius of curvature. When circumferential tensile stress is transmitted to the stress-relief crack-preventing holes 14, the smooth, rounded edges convert the circumferential tensile stress into dispersed stress along the tangent direction of the hole wall. The dispersed stress is evenly distributed circumferentially along the smooth, rounded edges. The smooth, rounded edges eliminate stress concentration points at the right-angle shear structure. The stress-relief crack-preventing holes 14 terminate the separation trajectory of the fibers at the edge of the I-shaped cut 10 under pressure tearing, preventing through-cut fracture of the flexible paper label substrate 1 along the outer edge of the vertical secondary cuts 12.

[0073] Working principle:

[0074] The printable wrap-around cigar traceability label is fed into the paper feed mechanism of the printing equipment in a flat, unfolded state. At this time, the I-shaped slit 10 that runs through the right-side printing display area 3 is formed by the perpendicular intersection of a horizontal main slit 11 and a vertical secondary slit 12. Micro-connection points 13 are distributed collinearly and at intervals inside the horizontal main slit 11 and the vertical secondary slit 12. The initial shear resistance threshold of the micro-connection points 13 is greater than the tangential friction force applied to the surface of the right-side printing display area 3 by the paper feed mechanism of the printing equipment. The micro-connection points 13 resist the pulling force of the tangential friction force, keeping the edges of the I-shaped slit 10 coplanar. This ensures that the right-side printing display area 3 is in a closed plane state, preventing the edges of the I-shaped slit 10 from detaching from the two-dimensional plane and forming a warped structure, blocking the path of the edges of the I-shaped slit 10 to the internal mechanical parts of the printing equipment, and eliminating the paper jam fault of the flexible paper label substrate 1 stuck inside the printing equipment. Subsequently, the printing equipment prints a QR code in the reserved printing area for the QR code on the front of the left adhesive area 2, and prints text data in the text data printing area on the front of the right-side printing display area 3.

[0075] After the graphic information is printed, the flexible paper label substrate 1 is bent and wraps around the outer wall of the single cigar column. During this process, the release protective layer 5 remains attached to the outside of the self-adhesive layer 4, and the release protective layer 5 is bonded to the left adhesive area 2 to form a composite structure layer. The multi-layered structure increases the local cross-sectional thickness of the flexible paper label substrate 1, and the composite structure layer provides longitudinal compressive stiffness support parallel to the penetration direction. The longitudinal compressive stiffness support resists the bending moment generated by the penetration thrust, preventing the left adhesive area 2 from buckling and folding deformation when subjected to the penetration thrust. The gradually tapered penetration guide end 6, formed by the inward contraction of the free edge of the left adhesive area 2, is vertically aligned with the I-shaped cut 10 from the inside of the right printing display area 3. The gradually tapered penetration guide end 6 is pressed into the I-shaped cut 10, applying a vertical thrust exceeding the compressive fracture threshold of the micro-connection point 13, and the micro-connection point 13 is broken by the force. The uncut fibers inside the micro-connection point 13 undergo shearing and separation, releasing the closure constraint. The I-shaped cut 10 is transformed into a through-open state, and the gradually interlacing guide end 6 guides the left bonding area 2 to pass through the transverse main cut 11 and out to the outside of the right printing display area 3.

[0076] Pulling the left bonding area 2 away from the right printing display area 3 causes the two edges of the left bonding area 2 near the junction with the right printing display area 3 to bulge outward, forming lateral anti-retraction latching wings 7. Since the total lateral width of the lateral anti-retraction latching wings 7 is greater than the lateral opening width of the lateral main cut 11, the lateral anti-retraction latching wings 7 are compressed and bend inward, penetrating and passing through the lateral main cut 11. After penetrating, they are released from their restraints, internal stress is released, and the lateral anti-retraction latching wings 7 return to their flat, unfolded state. Both ends are respectively inserted into the corresponding vertical secondary cut 12 and the stress-relieving crack-stopping hole 14. The outer edge contour of the lateral anti-retraction latching wings 7 and the edge contour of the I-shaped cut 10 form a spatial interference shield, creating a unidirectional mechanical locking interference between the lateral anti-retraction latching wings 7 and the I-shaped cut 10. The structure blocks the left adhesive area 2 from exiting the transverse main cut 11 along the insertion path. At the same time, the interlacing positioning bending line 8 set at the junction of the left adhesive area 2 and the right printing display area 3 is restricted and positioned by the one-way mechanical locking interference structure, and is aligned with the I-shaped cut 10 in parallel. The two ends of the flexible paper label substrate 1 are tightened, completing the self-centering parallel circumferential positioning for a single cigar column.

[0077] After establishing a self-centering parallel circumferential positioning, the release liner 5 is peeled off to expose the adhesive layer 4 on the back of the left adhesive area 2. The left adhesive area 2 is smoothly flattened and adhered along the interlacing positioning bend line 8. Because the adhesive layer 4 has an adhesive-free isolation strip 9 at the corresponding position of the interlacing positioning bend line 8, and the adhesive-free isolation strip 9 is located at the bend apex of the interlacing positioning bend line 8, the area is kept free of chemical adhesives. This provides an adhesive-free isolation space, preventing the left adhesive area 2 from being squeezed inwards when it undergoes a stepped bending deformation through the I-shaped cut 10, and preventing the adhesive layer 4 from overflowing due to compression. Subsequently, the left adhesive area 2 is pressed and fixed to the outer surface of the right printing display area 3 by the adhesive layer 4. The unidirectional mechanical locking structure established by the lateral anti-retraction latching wing 7 and the I-shaped cut 10, together with the adhesive structure established by the self-adhesive layer 4, jointly establish the double anchoring state of the flexible paper label substrate 1 after surrounding and covering the single cigar column, forming a double-layer interlocking mechanical labeling structure on the outside of the single cigar column.

[0078] When a single cigar column expands radially, generating outward tension, the radial compressive force is converted into circumferential tensile stress along the length of the flexible paper label substrate 1. This tension is transmitted to the junction of the interlacing positioning bending line 8 and the I-shaped cut 10. The interlacing positioning bending line 8, in conjunction with a unidirectional mechanical locking interference structure, converts the vertical peeling stress generated by the outward expansion of the single cigar column into shear stress parallel to the surface of the adhesive layer 4. The shear strength of the adhesive layer 4 against shear stress is greater than its peel strength against peeling stress, thus preventing delamination between the left adhesive area 2 and the right printed display area 3. Simultaneously, stress-relieving and crack-preventing holes 14 are provided at both ends of the vertical secondary cut 12. These holes are circular through-holes with smooth, rounded edges. When the circumferential tensile stress is transmitted to the ends, the stress-relieving and crack-preventing holes 14 disperse the concentrated tensile stress at the ends of the I-shaped cut 10 into circumferential tensile stress distributed around the edge of the hole wall. The smooth, rounded edges eliminate stress concentration points at right-angle shear structures, prevent cracks from spreading within the flexible paper label substrate 1, and maintain the stability of the ring-shaped fixed label structure.
