Description

Technical Field

[0001] This patent belongs to the field of stationery technology, specifically relating to a pen packaging box. Background Technology

[0002] Pens are writing tools, including pencils, watercolor pens, markers, crayons, etc. For ease of use, they are generally designed as long, thin cylinders. For example, markers are typically used to quickly express design concepts and create design renderings. They come in single-tipped and double-tipped versions, and the ink is available in alcohol-based, oil-based, and water-based types. They can quickly express effects and are one of the most important drawing tools today. Markers come in a wide variety of colors, often exceeding a hundred, and are characterized by quick drawing, rich color palettes, and strong expressive power. Due to their structural design, markers are suitable for both drawing and writing. To accommodate the different color requirements in drawing and writing, they are usually housed in a box to hold a set of markers in different colors, making it easy to access and use different colors.

[0003] However, when multiple pens or different types of pens are sold together, they are usually accompanied by outer packaging. Most existing pen packaging boxes used to store pens are vertically oriented, bucket-like structures. When users are faced with a variety of pens of different types or colors, to prevent them from slipping out, the pen cases or holders are placed upright. Users often need to stand up or adjust their posture to clearly see the pen type or color markings. Furthermore, these bucket-shaped pen packaging boxes are prone to shaking, collisions, shifting positions, or tipping over during transportation and carrying. This bucket-shaped structure is inconvenient for showing users different pen types or colors for easy selection, and it also causes inconvenience when taking, storing, and carrying pens. Additionally, this bucket-shaped packaging box lacks stability and is easily tipped over by consumers. It is also prone to shaking when carrying or moving the packaging box, thus shortening the lifespan of the pens.

[0004] In addition, pen packaging boxes on the market are usually made of PP material with top and bottom lids. This simple structure, with the two lids connected by a hinge and molded as a single piece, can easily cause aesthetic fatigue among users, fail to fully showcase the brand image of the pen, and lack product innovation.

[0005] Therefore, it is necessary to design a highly innovative, uniquely shaped pen packaging box that allows users to easily identify the pen's logo color and pick up the pen, while also being easy to take, carry, and fully showcasing the brand image. Utility Model Content

[0006] The purpose of this patent is to obtain a highly innovative, uniquely designed pen packaging box that allows users to easily identify the type and color of the pen, while also being easy to handle, carry, and fully showcasing the brand image.

[0007] To solve the above technical problems: This patent provides a pen packaging box, which includes an inner shell and an outer shell. The top of the inner shell has a storage opening for storing pens. The outer shell is a frame structure for closing the storage opening. The inner shell and the outer shell are rotated and fixed by a rotating structure. The inner shell can rotate relative to the outer shell about the rotating structure as an axis, so that the pen packaging box can change between a closed state and an open state. When the pen packaging box is in the first use state, the outer shell closes the storage opening. When the pen packaging box is in the second use state, the inner shell and the outer shell are in an X shape to keep it upright and allow pens to be placed and removed.

[0008] Furthermore, the rotating structure is a latch, with first limiting holes symmetrically provided on both sides of the inner shell, a first protrusion extending inward on one side of the outer shell, and a second limiting hole on the other side of the outer shell; the latch passes through the second limiting hole and the first limiting hole in sequence to achieve an interference fit of the latch, so that the outer shell is sleeved on the outside of the inner shell, and the latch reciprocates around the second limiting hole and the first limiting hole as the axis.

[0009] The rotating structure is a latch, with first limiting holes symmetrically provided on both sides of the inner shell and second limiting holes symmetrically provided on both sides of the outer shell; the latch passes through the second limiting hole and the first limiting hole in sequence to achieve an interference fit, so that the outer shell is sleeved on the outside of the inner shell, and the latch reciprocates around the limiting hole as an axis.

[0010] Furthermore, the first boss is at least two-thirds circular or heart-shaped, and includes a recess and a guide portion; the guide portion is located at the bottom of the first boss and is a ramp, used to guide the inner shell during assembly.

[0011] Furthermore, the latch includes a cylindrical boss, and a through hole is provided on the upper part of the first boss, the through hole including a first through hole and a second through hole.

[0012] Furthermore, a cylindrical boss extends into the first through hole, the height of which is less than or equal to the thickness of the through hole, and is used to secure the latch to the outer casing.

[0013] Furthermore, the latch also includes a snap-fit ​​structure, which has a snap-fit ​​groove, a hook, and a U-shaped groove; the snap-fit ​​groove, hook, U-shaped groove, and cylindrical boss are all made of the same material and are integrally connected.

[0014] Furthermore, the snap-fit ​​groove and the limiting hole are on the same horizontal plane, and the width of the snap-fit ​​groove is greater than the sum of the thicknesses of the second through hole and the second limiting hole.

[0015] Furthermore, the hook is a protruding arc-shaped component on the snap-fit ​​structure, located on the side of the snap-fit ​​structure closer to the inner shell, so that the minimum outer diameter of the snap-fit ​​structure is greater than the minimum inner diameter of the second through hole and the second limiting hole.

[0016] Furthermore, the U-shaped groove is formed by material reduction to deform the snap-fit ​​structure so that the latch can be inserted into the second through hole and the second limiting hole, and the hook protrudes from the inside of the inner shell to prevent the inner shell from falling off the outer shell.

[0017] The rotating structure is a locking structure, with first limiting holes symmetrically provided on both sides of the inner shell and first protrusions symmetrically provided on both sides of the outer shell; the first protrusions pass through the first limiting holes to form a locking structure.

[0018] The rotating structure is a locking structure, with fixed parts on both sides of the inner shell at the same horizontal line; and matching parts on both sides of the outer shell corresponding to the limiting holes. The inner shell is fixed inside the outer shell by the tight fit between the fixed parts and the matching parts, and the inner shell is rotated and limited by the locking structure.

[0019] Furthermore, the fixing part is a first protrusion extending outward; the matching part is a limiting hole that fits tightly with the first protrusion extending outward.

[0020] The fixing part is an outwardly extending protruding structure, which includes a cylindrical part and an arc-shaped part; the matching part is a hole-like structure, which includes a cylindrical hole and an arc-shaped hole.

[0021] Furthermore, the cylindrical part is tightly fitted into the cylindrical hole; the arc-shaped part is set in the arc-shaped hole, and the projected area of ​​the arc-shaped hole is 1.5 to 3.0 times the projected area of ​​the arc-shaped part, so that the arc-shaped part can rotate and be limited in the arc-shaped hole.

[0022] Furthermore, the height of the arc-shaped component is equal to the depth of the arc-shaped hole, and the arc-shaped component and the arc-shaped hole have the same shape, with both having rectangular cross-sections.

[0023] The arc-shaped component can be chosen at will. The height of the arc-shaped component is greater than the depth of the arc-shaped hole. The arc-shaped component and the arc-shaped hole have different shapes. The cross-section of the arc-shaped component is trapezoidal or hook-shaped, and the cross-section of the arc-shaped hole is rectangular. It is used to fix the arc-shaped component to the arc-shaped hole.

[0024] Furthermore, the fixing part also includes a limiting guide block, which is integrally connected with the arc-shaped part; the matching part also includes a gear structure that cooperates with the limiting guide block to adapt to different rotation angles of the inner shell and to limit the rotation.

[0025] Furthermore, the fixing part also includes at least one limiting protrusion, and the matching part includes at least three limiting grooves; the number of limiting protrusions is less than the number of limiting grooves, and the limiting protrusions can slide between different limiting grooves along the movement trajectory of the arc-shaped member to adapt to different rotation angles of the inner shell and perform limiting.

[0026] Alternatively, the fixing part may include at least three limiting grooves, and the matching part may include at least one limiting protrusion; the number of limiting protrusions is less than the number of limiting grooves, and the limiting protrusions can slide between different limiting grooves along the movement trajectory of the arc-shaped member to adapt to different rotation angles of the inner shell and perform limiting.

[0027] Furthermore, the inner shell can be rotated 30-60 degrees, 60-90 degrees, 90-120 degrees, 120-135 degrees, or 135-150 degrees by a rotating structure before being limited.

[0028] Furthermore, the outer shell is equipped with buckles and a back panel; the buckles and back panel are integrated with the outer shell.

[0029] Furthermore, the latch is located on the inner wall of the outer shell frame structure near the back plate; when the inner shell and outer shell rotate back to close from the open position, there is a damping feedback.

[0030] Furthermore, the pen packaging box also includes a mesh element, which is located inside the inner shell, in the middle of the pen barrel. The mesh element includes a mesh base and a groove.

[0031] Furthermore, the mesh matrix has multiple cavities for accommodating pens.

[0032] Furthermore, the grooves are symmetrically arranged on both sides of the grid base to accommodate the limiting structure.

[0033] Furthermore, the inner shell also includes at least two fixing protrusions and at least two limiting ribs.

[0034] Furthermore, the bottom end of the limiting rib is connected to the bottom of the inner shell, and the top end of the limiting rib is at the same height; the fixing protrusion is located on the same horizontal plane and is set above the limiting rib; the distance between the top end of the limiting rib and the fixing protrusion is equal to the thickness of the mesh component, so that the mesh component is fixed between the limiting rib and the fixing protrusion after being assembled into the inner shell.

[0035] Furthermore, the pen packaging box also includes a carrying strap, which is connected to one side of the pen packaging box via a first mounting part and a second mounting part, which are located on both sides of the shaft; when the carrying strap is in use, the carrying strap is arched in shape.

[0036] Furthermore, the carrying strap has mounting holes, through which it is fitted onto the second protrusion of the outer shell for carrying the pen packaging box.

[0037] Furthermore, the second boss has a T-shaped longitudinal section and includes a left boss and a right boss, which are symmetrically arranged on one side of the outer shell along the axial direction of the outer shell.

[0038] Furthermore, the carrying strap is also provided with through grooves, including a first through groove and a second through groove; the mounting holes include a first mounting hole, a second mounting hole, a third mounting hole and a fourth mounting hole.

[0039] Furthermore, the first through groove is located between the first mounting hole and the second mounting hole, and is used to connect the first mounting hole and the second mounting hole; the second through groove is located between the third mounting hole and the fourth mounting hole, and is used to connect the third mounting hole and the fourth mounting hole.

[0040] Furthermore, when the carrying strap is in a flat state, the second mounting hole is fitted onto the left boss, and the third mounting hole is fitted onto the right boss.

[0041] Furthermore, when the carrying strap is in use, the first mounting hole is fitted onto the left boss and the fourth mounting hole is fitted onto the right boss, for carrying the pen packaging box.

[0042] Furthermore, the handles can be made of soft materials such as leather, rubber, silicone, nylon, and canvas. This reduces hand pressure during extended carrying and provides a more comfortable feel.

[0043] Compared to existing technologies, it has the following beneficial effects: (1) The pen packaging box provided by this patent is highly innovative and has a unique shape. When the pen packaging box is opened, it is X-shaped and can be placed on a table or other flat surface. It has high stability and makes it easy for users to identify pens.

[0044] (2) By setting an arc-shaped groove on the inner shell and combining it with the appropriate spacing between the internal mesh parts, a pen storage area is formed that makes it easy for fingers to reach in to pick up or put down the pen, which significantly improves the convenience of picking up and putting down the pen and the user experience.

[0045] (3) By setting a grid inside the inner shell corresponding to the middle section of the pen barrel, lateral support and constraint can be provided in the middle of the pen, thereby effectively limiting the movement of the pen in all directions inside the pen packaging box, preventing it from shaking, colliding with each other, shifting its position or tipping over during transportation and carrying, and ensuring that each pen can be firmly held in its predetermined position. At the same time, the grid can be flexibly configured and arranged according to different pen types or different specifications to meet the needs of various pen combinations.

[0046] (4) The flexible carrying strap makes it easy for users to carry. For direct-liquid ink pens, the strap is parallel to the pen's axis, ensuring the packaging remains horizontal during transport. This design addresses the physical limitation of direct-liquid ink pens, preventing ink backflow or leakage when the pen is placed vertically with the nib facing down, or ink backflow due to gravity when the nib is placed vertically with the nib facing up, which could affect ink flow after initial use or prolonged storage. For non-direct-liquid ink pens, the carrying strap can be perpendicular to the pen's axis. This unique packaging design also effectively showcases the brand image and stimulates consumer purchasing desire. Attached Figure Description

Unless otherwise specified, the experimental methods described in the various embodiments of this patent are conventional methods, and the materials used in the following embodiments, unless otherwise specified, are commercially available.

[0069] Example 1

[0070] like Figures 1-17The illustration shows a specific embodiment of this patent, providing a multifunctional pen packaging box, including a mesh component 100, an inner shell 200, an outer shell 300, a latch 400, and a carrying strap 500; the mesh component 100 is located inside the inner shell 200; the inner shell 200 is a box structure with an opening at the top, and includes limiting holes symmetrically arranged on both sides of the inner shell 200, including a first limiting hole 210a and a second limiting hole 210b; the outer shell 300 is a frame structure, and has a through hole, an inwardly extending first protrusion 310, and an outwardly extending... The second protrusion extends; the first protrusion 310 can pass through the first limiting hole 210a and is symmetrical with the through hole, so that the outer shell 300 is fitted on the outside of the inner shell 200; the latch 400 can undergo elastic deformation and pass through the through hole and the second limiting hole 210b in sequence, and the inner shell 200 can rotate 90 degrees with the latch 400 and the first protrusion 310 as limiting axes. At this time, the pen packaging box is in an X-shaped open state for storing or taking out the pen 1; the carrying strap 500 is provided with a mounting hole, and the carrying strap 500 is fitted on the second protrusion through the mounting hole for carrying the pen packaging box.

[0071] Specifically, the mesh component 100 includes a mesh base 110 and grooves 130, with the grooves 130 symmetrically arranged on both sides of the mesh base 110.

[0072] Specifically, the grid base 110 has multiple receiving cavities 120 inside. The receiving cavities 120 are of uniform size and the spacing between them is uniform, which is used to receive the pen 1 so that the pen 1 is neatly arranged.

[0073] In some other embodiments, the sizes of the receiving cavities 120 may vary, but the spacing between the receiving cavities 120 is uniform. The size of the receiving cavities 120 can be adjusted according to the user's needs for the purpose or size of the pen 1. Optionally, the receiving cavities 120 are all the same size, and the spacing between them is also uniform, but multiple rows of receiving cavities 120 are arranged in a staggered manner to fully display the color number or category of the pen 1 and to facilitate the removal and return of the pen 1. In other embodiments, the arrangement of the receiving cavities can also be flexibly configured according to different specifications of the product (such as 12-color, 24-color, 36-color, or 48-color pens), for example, 2×6, 12×2, 12×3, 12×4 layouts, to adapt to the combination needs of various pens.

[0074] Specifically, the inner shell 200 is a box-like structure with an opening at the top. The inner shell 200 is rectangular in shape, with an arc-shaped structure at the opening. There are 1-3 cm notches on both side walls of the inner shell 200 to allow users to easily insert their fingers into the pen storage area, significantly improving the convenience of retrieving and storing pens and enhancing the user experience. In some other embodiments, the inner shell 200 may also be square or have a regular curved structure.

[0075] Specifically, the inner shell 200 includes at least two fixing protrusions 220 and at least two limiting ribs 230 for controlling the insertion depth of the mesh element 100.

[0076] Specifically, the fixed protrusion 220 has a semi-circular arc structure, the limiting rib 230 has a strip structure, a hemispherical structure, and the top of the other limiting rib 230 has a flat structure.

[0077] Preferably, the inner shell 200 is provided with four fixing protrusions 220 and four limiting ribs 230. The bottom ends of the four limiting ribs 230 are vertically connected to the bottom of the inner shell 200, and the top ends of the four limiting ribs 230 are at the same height. The four fixing protrusions 220 are located on the same horizontal plane and are all vertically arranged above the four limiting ribs 230. The distance between the top ends of the four limiting ribs 230 and the four fixing protrusions 220 is equal to the thickness of the mesh member 100, so that the mesh member 100 can be fixed between the limiting ribs 230 and the fixing protrusions 220 after being assembled into the inner shell 200.

[0078] Optionally, the inner shell 200 is provided with two fixing protrusions 220 and two limiting ribs 230. The bottom ends of the two limiting ribs 230 are vertically connected to the bottom of the inner shell 200, and the top ends of the two limiting ribs 230 are at the same height and are asymmetrically arranged on different inner walls of the inner shell 200, for example, in the "first and third quadrants" of a "four-quadrant" arrangement. The two fixing protrusions 220 are located on the same horizontal plane and are asymmetrically arranged on different inner walls of the inner shell 200, for example, in the "second and fourth quadrants" of a "four-quadrant" arrangement. They are both vertically arranged above the two limiting ribs 230. This allows the mesh component 100 to be fixed between the limiting ribs 230 and the fixing protrusions 220 after being assembled into the inner shell 200.

[0079] Optionally, the inner shell 200 is provided with two fixing protrusions 220 and two limiting ribs 230. The bottom ends of the two limiting ribs 230 are inclinedly connected to the bottom of the inner shell 200, but the top ends of the two limiting ribs 230 are at the same height, and the two limiting ribs 230 are asymmetrically arranged on different inner walls of the inner shell 200. The two fixing protrusions 220 are located on the same horizontal plane and are complementary to the two limiting ribs 230. That is, the two fixing protrusions 220 are perpendicular to the bottom of the two limiting ribs 230, so that the mesh member 100 can be fixed between the limiting ribs 230 and the fixing protrusions 220 after being assembled into the inner shell 200.

[0080] More specifically, the mesh element 100 is disposed in the middle section of the pen barrel of the pen 1, providing lateral support and constraint in the middle of the pen 1, thereby effectively limiting the movement of the pen 1 in all directions inside the pen packaging box, preventing it from shaking, colliding with each other, shifting in position, or tipping over during transportation and carrying, and ensuring that each pen can be securely held in its predetermined position. In some other specific embodiments, the mesh element can also be disposed at the end near the inner shell 200 for retrieving the pen 1.

[0081] Specifically, the inner shell 200 has symmetrically provided limiting holes on both sides, including a first limiting hole 210a and a second limiting hole 210b.

[0082] Specifically, the shape of the limiting hole is irregular, and the irregular shape can be an incomplete circular structure; preferably, the shape of the limiting hole is a 7 / 8 circular structure or a 3 / 4 circular structure.

[0083] Specifically, the outer shell 300 is fitted over the inner shell 200, and the inner wall of the outer shell 300 is provided with an inwardly extending first protrusion 310. The first protrusion 310 has an irregular shape or a symmetrical structure with an arc. Preferably, the first protrusion 310 is a heart-shaped structure or a semi-circular structure. The minimum outer diameter of the first protrusion 310 is 0.3~0.5 mm, 0.5~0.7 mm, or 0.7~1.0 mm smaller than the minimum inner diameter of the first limiting hole 210a, so that the first protrusion 310 can be fitted over the outside of the first limiting hole 210a.

[0084] Specifically, the first boss 310 includes a recessed portion 311 and a guide portion 312. The guide portion 312 is located at the bottom of the first boss 310 and is a ramp. It can play a guiding role when the inner shell 200 is assembled, so that the inner shell 200 can be smoothly assembled onto the outer shell 300 through the first limiting hole 210a. The recessed portion 311 can limit the inner shell 200 after it rotates 90 degrees through the first limiting hole 210a.

[0085] Specifically, the outer casing 300 is provided with through holes, which are symmetrical to the position of the first boss 310. The through holes include a first through hole 330 and a second through hole 340.

[0086] Specifically, the latch 400 is on the same horizontal plane as the through hole, the limiting hole, and the first boss 310. Specifically, the latch 400 includes a cylindrical boss 410 and a snap-fit ​​structure 420.

[0087] Specifically, the height of the cylindrical boss 410 is equal to the thickness of the first through hole 330, so that the cylindrical boss 410 can extend into the first through hole 330. The cylindrical boss 410 is flush with the inner wall of the outer shell 300 and is used to fix the latch 400 to the outer shell 300.

[0088] Optionally, the height of the cylindrical boss 410 is less than the thickness of the first through hole 330, so that the cylindrical boss 410 is located inside the first through hole 330 and does not protrude from the inner wall of the outer shell 300.

[0089] Specifically, the cylindrical boss 410 is tightly fitted into the first through hole 330 corresponding to the outer shell 300. This prevents the main body parts of the snap-fit ​​structure 420 from becoming loose during the rotation of the inner shell 200 or after the rotation stops, and strengthens the stability of the latch 400.

[0090] Specifically, the snap-fit ​​structure 420 is an irregularly shaped structure or a symmetrical structure with an arc. Preferably, the snap-fit ​​structure 420 is a heart-shaped structure or a semi-circular structure; the height of the snap-fit ​​structure 420 is greater than the sum of the thicknesses of the second through hole 340 and the second limiting hole 210b, so that the snap-fit ​​structure 420 can pass through the through hole and the second limiting hole 210b in sequence and protrude from the inner wall of the inner shell 200.

[0091] Specifically, the snap-fit ​​structure 420 is interference-fitted with the second through hole 340 and the second limiting hole 210b.

[0092] Specifically, the snap-fit ​​structure 420 is provided with at least one U-shaped groove 423; the U-shaped groove 423 is formed by subtractive processing of the snap-fit ​​structure 420. Preferably, the number of U-shaped grooves 423 is two.

[0093] Specifically, a snap-fit ​​groove 421 and a hook 422 are provided between the two U-shaped grooves 423. The material reduction design of the U-shaped grooves 423 enables the snap-fit ​​grooves 421 and hooks 422 to produce a certain elastic deformation.

[0094] Specifically, the snap-fit ​​groove 421, hook 422, U-shaped groove 423 and cylindrical boss 410 are made of the same material and are integrally connected.

[0095] Specifically, the snap-fit ​​groove 421 and the second limiting hole 210b are on the same horizontal plane. The width of the snap-fit ​​groove 421 is 0.3~0.5 mm, 0.5~0.7 mm or 0.7~1.0 mm greater than the sum of the thicknesses of the second through hole 340 and the second limiting hole 210b, so that the inner shell 200 can reciprocate with the groove 130 using the second limiting hole 210b.

[0096] Specifically, the hook 422 is a protruding arc-shaped component on the snap-fit ​​structure 420, located on the side of the snap-fit ​​structure 420 near the inner shell 200, so that the minimum outer diameter of the snap-fit ​​structure 420 is greater than the minimum inner diameter of the second through hole 340 and the second limiting hole 210b.

[0097] Specifically, when the latch 400 is in the state of being inserted into the second through hole 340 and the second limiting hole 210b, the snap-fit ​​structure 420 undergoes a first deformation, and the first deformation displacement changes from the first position to the second position.

[0098] Specifically, when the latch 400 is fully inserted into the second through hole 340 and the second limiting hole 210b, the locking structure 420 undergoes a second deformation, that is, the locking structure 420 returns to its original state, changing from the second position to the first position. The hook 422 on the locking structure 420 protrudes from the inner wall of the inner shell 200, preventing the inner shell 200 from falling off the outer shell 300. At this time, the latch 400 and the first boss 310 together act as a limiting axis, enabling the inner shell 200 to reciprocate.

[0099] Specifically, the inner shell 200 can rotate via a limiting shaft using the first limiting hole 210a and the second limiting hole 210b; the limiting angle of rotation is 30~60 degrees, 60~90 degrees, 90~120 degrees, 120~135 degrees or 135~150 degrees, at which time the pen packaging box is in an X-shaped open state, used for displaying, storing or taking out the pen.

[0100] Specifically, the outer casing 300 is also equipped with a buckle 370 and a back plate, which are integrated with the outer casing 300.

[0101] Specifically, the buckle 370 is located on the inner wall of the outer shell 300 frame structure near the back panel; when the inner shell 200 and the outer shell 300 rotate back to close from the open position, there is a damping feedback, allowing the user to fully feel that the pen packaging box is completely closed, preventing the pen packaging box from being easily opened and causing the pen 1 to fall out.

[0102] Specifically, the back panel includes a first baffle 350 and a second baffle 360. The first baffle 350 is positioned on the upper part of the outer shell 300 and engages with the snap fastener 370, allowing the inner shell 200 to rotate 30-60 degrees, 60-90 degrees, 90-120 degrees, 120-135 degrees, or 135-150 degrees away from the first baffle 350. The second baffle 360 ​​is positioned on the lower part of the outer shell 300 and fills the gap between the inner shell 200 and the outer shell 300, creating a more three-dimensional appearance.

[0103] Specifically, the outer casing 300 also has a second outwardly extending boss, the longitudinal section of which is T-shaped. Optionally, the lower part of the second boss is a cylinder and the upper part is a hemisphere.

[0104] Specifically, the second boss includes a left boss 320a and a right boss 320b, which are symmetrically arranged on both sides of the through hole along the axial direction of the outer shell 300.

[0105] Specifically, the carrying strap 500 is provided with mounting holes and through slots. The mounting holes include a first mounting hole 510a, a second mounting hole 510b, a third mounting hole 510c, and a fourth mounting hole 510d; the through slots include a first through slot 520a and a second through slot 520b.

[0106] Specifically, the first through groove 520a is located between the first mounting hole 510a and the second mounting hole 510b, and is used to connect the first mounting hole 510a and the second mounting hole 510b; the second through groove 520b is located between the third mounting hole 510c and the fourth mounting hole 510d, and is used to connect the third mounting hole 510c and the fourth mounting hole 510d.

[0107] Specifically, when the carrying strap 500 is in a flat state, the second mounting hole 510b is fitted onto the left boss 320a, and the third mounting hole 510c is fitted onto the right boss 320b; when the carrying strap 500 is in use, the carrying strap 500 moves along the first through groove 520a and the second through groove 520b toward the buckle 400. At this time, the carrying strap 500 is in an arch shape, the first mounting hole 510a is fitted onto the left boss 320a, and the fourth mounting hole 510d is fitted onto the right boss 320b, for carrying the pen packaging box.

[0108] More specifically, the carrying strap 500 is parallel to the pen barrel axis of pen 1, ensuring that the user keeps the pen packaging box horizontal during carrying. This design feature echoes the physical characteristic that direct-ink pens should not be placed vertically, effectively avoiding ink backflow and leakage that may occur when the pen tip is placed vertically with the tip down, or ink backflow due to gravity that may occur when the pen tip is placed vertically with the tip up, thus affecting the smoothness of ink flow after first use or long-term storage.

[0109] More specifically, the handle 500 can be made of soft materials such as leather, rubber, silicone, nylon, and canvas. This reduces hand pressure during long-term carrying and provides a more comfortable feel.

[0110] Example 2

[0111] like Figures 18-20As shown, this is the second specific embodiment of the present patent. Compared with embodiment 1, the difference lies in the different assembly methods of the outer shell 300a and the inner shell 200a in this embodiment. That is, both sides of the outer shell 300a and the inner shell 200a are fitted with an interference fit of the locking buckle 400a.

[0112] Specifically, the outer shell 300a has a first through hole 330a and a second through hole 340a symmetrically arranged on both sides, and the latches 400a are symmetrically arranged on both sides of the outer shell 300a so that the inner shell 200a is fixed inside the outer shell 300a.

[0113] Example 3

[0114] like Figures 21-22 As shown, this is the third specific embodiment of the present patent. Compared with embodiment 1, the difference lies in the different assembly methods of the outer shell 300b and the inner shell 200b in this embodiment. That is, the outer shell 300b and the inner shell 200b are not fixed by the latch 400b. The inner wall of the outer shell 300b is symmetrically provided with an inwardly extending first protrusion 310a, so that the inner shell 200b is smoothly assembled onto the first protrusion 310a on the outer shell 300b through the first limiting hole 1210a and rotated for limiting.

[0115] Specifically, the outer shell 300b is fitted over the inner shell 200b. The first protrusion 310a has an irregular shape or a symmetrical structure with an arc. Preferably, the first protrusion 310a is a heart-shaped structure or a semi-circular structure. The minimum outer diameter of the first protrusion 310a is 0.3~0.5 mm, 0.5~0.7 mm, or 0.7~1.0 mm smaller than the minimum inner diameter of the first limiting hole 1210a, so that the first protrusion 310a can be fitted over the outer side of the first limiting hole 1210a. This allows the first protrusion 310a and the first limiting hole 1210a to form a rotating structure, and the inner shell 200b can rotate 30~135 degrees relative to the outer shell 300b about the rotating structure before being limited.

[0116] Example 4

[0117] like Figures 23-25 As shown, this is the fourth specific embodiment of the present patent. Compared with embodiment 3, the difference lies in the different assembly methods of the outer shell 300c and the inner shell 200c. Specifically, the outer wall of the inner shell 200c is symmetrically provided with an outwardly extending first fixing part 240a, and the two sides of the outer shell 300c are symmetrically provided with first matching parts 380a, so that the inner shell 200c is smoothly assembled onto the first matching part 380a on the outer shell 300c through the first fixing part 240a and rotated and limited.

[0118] Specifically, the outer shell 300c is fitted over the inner shell 200c. The first fixing part 240a has an irregular shape or a symmetrical structure with an arc. Preferably, the first fixing part 240a is a heart-shaped structure or at least a semi-circular structure. The minimum outer diameter of the first fixing part 240a is 0.3~0.5 mm, 0.5~0.7 mm or 0.7~1.0 mm smaller than the minimum inner diameter of the first matching part 380a, so that the first matching part 380a can be fitted over the outside of the first fixing part 240a.

[0119] Specifically, the first mating part 380a is at least two-thirds circular in structure, and the first fixing part 240a is tightly fitted into the first mating part 380a. The projected area of ​​the first mating part 380a is larger than the projected area of ​​the first fixing part 240a, so that the inner shell 200c is smoothly assembled onto the first mating part 380a of the outer shell 300c through the first fixing part 240a. The inner shell 200c can be limited after rotating 30 to 135 degrees through the first fixing part 240a.

[0120] Example 5

[0121] like Figures 26-28 As shown, this is the fifth specific embodiment of the present patent. Compared with embodiment 4, the difference lies in the different assembly methods of the outer shell 300d and the inner shell 200d in this embodiment. Specifically, the outer wall of the inner shell 200d is symmetrically provided with an outwardly extending second fixing part 240b, and the two sides of the outer shell 300d are symmetrically provided with second matching parts 380b, so that the inner shell 200d is smoothly assembled onto the second matching part 380b on the outer shell 300d through the second fixing part 240b and rotated and limited.

[0122] Specifically, the second fixing part 240b includes a first cylindrical member 240b1 and a first arc-shaped member 240b2, with the first cylindrical member 240b1 located at the center of the first arc-shaped member 240b2.

[0123] Specifically, the second mating part 380b includes a first cylindrical hole 380b1 and a first arc-shaped hole 380b2, and the second mating part 380b is an integrally connected design; the first cylindrical hole 380b1 is located at the center of the first arc-shaped hole 380b2.

[0124] More specifically, the height of the second fixing part 240b is the same as the depth of the second matching part 380b. The first cylindrical member 240b1 is assembled onto the first cylindrical hole 380b1, and the first arc-shaped member 240b2 is assembled onto the first arc-shaped hole 380b2. The projected area of ​​the first arc-shaped hole 380b2 is twice the projected area of ​​the first arc-shaped member 240b2, allowing the first arc-shaped member 240b2 to rotate 90 degrees within the first arc-shaped hole 380b2 and be limited. In some other embodiments, the projected area of ​​the first arc-shaped hole 380b2 can also be 1.5 to 3.0 times the projected area of ​​the first arc-shaped member 240b2, allowing the first arc-shaped member 240b2 to rotate 30 to 135 degrees within the first arc-shaped hole 380b2 and be limited.

[0125] Example 6

[0126] like Figures 29-30 As shown, this is the sixth specific embodiment of the present patent. Compared with embodiment 5, the difference lies in the different assembly methods of the outer shell 300e and the inner shell 200e. Specifically, the outer wall of the inner shell 200e is symmetrically provided with an outwardly extending third fixing part 240c, and the outer shell 300e is symmetrically provided with a third matching part 380c on both sides. Then, the inner shell 200e is fixed inside the outer shell 300e by the locking buckle 400b passing through the third matching part 380c on the outer shell 300e and the third fixing part 240c on the inner shell 200e in sequence, and the rotation is limited by the cooperation of the third fixing part 240c and the third matching part 380c.

[0127] Specifically, the third fixing part 240c is arc-shaped, and the third matching part 380c includes a second cylindrical hole 380c1 and a second arc-shaped hole 380c2. The height of the third fixing part 240c is the same as the depth of the third matching part 380c, so that the third fixing part 240c is assembled onto the second arc-shaped hole 380c2. The projected area of ​​the second arc-shaped hole 380c2 is twice the projected area of ​​the third fixing part 240c, so that the third fixing part 240c can rotate 90 degrees within the second arc-shaped hole 380c2 and be limited.

[0128] More specifically, the latch 400a is fitted onto the second cylindrical hole 380c1 via an interference fit to secure the inner shell 200e and the outer shell 300e. In some embodiments, the latch 400b can have the same structure as the latch 400 in Embodiment 1, simply scaled down proportionally to ensure it can fit onto the second cylindrical hole 380c1. In other embodiments, the latch 400b has a symmetrical structure, with a groove inside for an interference fit to secure the inner shell 200e and the outer shell 300e.

[0129] In some other specific embodiments, the projected area of ​​the second arc-shaped hole 380c2 can also be 1.5 to 3.0 times the projected area of ​​the third fixing part 240c, so that the third fixing part 240c can rotate 30 to 135 degrees within the second arc-shaped hole 380c2 and be limited.

[0130] Example 7

[0131] like Figure 31 As shown, this is the seventh specific embodiment of the present patent. Compared with embodiment 5, the difference lies in the assembly method of the outer shell 300f and the inner shell 200f in this embodiment. That is, the outer wall of the inner shell 200f is symmetrically provided with an outwardly extending fourth fixing part 240d, and the outer shell 300f is symmetrically provided with a fourth matching part 380d on both sides, so that the inner shell 200f is smoothly assembled to the fourth matching part 380d on the outer shell 300f through the fourth fixing part 240d and rotated and limited.

[0132] Specifically, the fourth fixing part 240d includes a second cylindrical member 240d1 and a second arc-shaped member 240d2; the second arc-shaped member 240d2 is an outwardly extending trapezoidal structure symmetrical about the second cylindrical member 240d1. Specifically, the fourth matching part 380d includes a third cylindrical hole 380d1 and a third arc-shaped hole 380d2, and the fourth matching part 380d is an integrally formed design; the third cylindrical hole 380d1 is located at the center of the third arc-shaped hole 380d2.

[0133] More specifically, the height of the fourth fixing part 240d is the same as the depth of the fourth matching part 380d, the second cylindrical part 240d1 is assembled onto the third cylindrical hole 380d1, and the second arc-shaped part 240d2 is assembled onto the third arc-shaped hole 380d2 and protrudes from the third arc-shaped hole 380d2, so that the outwardly extending trapezoidal structure is fixed on the outside of the outer shell 300f.

[0134] More specifically, the projected area of ​​the third arc-shaped hole 380d2 is twice the projected area of ​​the second arc-shaped member 240d2, so that the second arc-shaped member 240d2 can rotate 90 degrees within the third arc-shaped hole 380d2 and be limited.

[0135] In some other embodiments, the projected area of ​​the third arc-shaped hole 380d2 can be 1.5 to 3.0 times the projected area of ​​the second arc-shaped member 240d2, allowing the second arc-shaped member 240d2 to rotate 30 to 135 degrees within the third arc-shaped hole 380d2 and be limited in position. In other embodiments, the height of the second arc-shaped member 240d2 can be the same as the depth of the third arc-shaped hole 380d2.

[0136] Example 8

[0137] like Figure 32 The image shows the eighth specific embodiment of this patent. Compared with embodiment 7, the difference is that the carrying strap 500a in this embodiment is located on the short side of the outer shell 300g. It is suitable for non-direct-liquid pen products such as pencils, avoiding ink backflow and leakage that may occur when the pen tip is placed vertically with the tip facing down, or ink backflow due to gravity that may occur when the pen tip is placed vertically with the tip facing up, thus affecting the smoothness of ink flow after first use or long-term storage.

[0138] Example 9

[0139] like Figures 33-34 As shown, this is the ninth specific embodiment of the present patent. Compared with embodiment 8, the difference lies in the different assembly methods of the outer shell 300h and the inner shell 200h in this embodiment. Specifically, the outer wall of the inner shell 200h is symmetrically provided with an outwardly extending fifth fixing part 240e, and the outer shell 300h is symmetrically provided with a fifth matching part 380e on both sides. This allows the inner shell 200h to be assembled to the fifth matching part 380e on the outer shell 300h through the fifth fixing part 240e, and to be rotated and limited by the engagement between the fifth fixing part 240e and the fifth matching part 380e.

[0140] Specifically, the fifth fixing part 240e includes a third cylindrical member 240e1, at least one third arc-shaped member 240e2, and at least one arc-shaped guide block 240e3; wherein the arc-shaped guide block 240e3 and the third arc-shaped member 240e2 are integrally connected to form a cylindrical gear.

[0141] Specifically, the fifth matching part 380e includes a fourth cylindrical hole 380e1, a gear structure 380e2 and a fourth arc-shaped hole 380e3. The fourth cylindrical hole 380e1 is located at the center of the gear structure 380e2, and the height of the third arc-shaped member 240e2 is greater than the depth of the fourth arc-shaped hole 380e3.

[0142] More specifically, the third cylindrical component 240e1 is assembled onto the fourth cylindrical hole 380e1, and the cylindrical gear is assembled into the fourth arc-shaped hole 380e3 and abuts against the gear structure 380e2. The projected area of ​​the fourth arc-shaped hole 380e3 is more than twice the projected area of ​​the cylindrical gear, allowing the cylindrical gear to rotate and be limited within the fourth arc-shaped hole 380e3 along the gear structure 380e2, with a limiting angle of 15~135 degrees.

[0143] In some other embodiments, the projected area of ​​the fourth arc-shaped hole 380e3 can be 1.5 to 3.0 times the projected area of ​​the cylindrical gear. In other embodiments, the height of the third arc-shaped member 240e2 can be the same as the depth of the fourth arc-shaped hole 380e3.

[0144] Example 10

[0145] like Figures 35-36 As shown, this is the tenth specific embodiment of the present patent. Compared with embodiment 9, the difference lies in the different assembly methods of the outer shell 300i and the inner shell 200i. Specifically, the outer wall of the inner shell 200i is symmetrically provided with an outwardly extending sixth fixing part 240f, and the outer shell 300i is symmetrically provided with a sixth matching part 380f on both sides. This allows the inner shell 200i to be assembled to the sixth matching part 380f on the outer shell 300i through the sixth fixing part 240f, and to be rotated and limited by the engagement between the sixth fixing part 240f and the sixth matching part 380f.

[0146] Specifically, the sixth fixing part 240f includes a fourth cylindrical member 240f1, a fourth arc-shaped member 240f2, and at least one limiting protrusion 240f3; the fourth arc-shaped member 240f2 and the limiting protrusion 240f3 are both centered on the fourth cylindrical member 240f1.

[0147] Specifically, the sixth matching part 380f includes a fifth cylindrical hole 380f1, a fifth arc-shaped hole 380f2, and at least three limiting grooves 380f3.

[0148] More specifically, the fourth cylindrical component 240f1 is assembled onto the fifth cylindrical hole 380f1, and the fourth arc-shaped component 240f2 is located on the fifth arc-shaped hole 380f2. The projected area of ​​the fifth arc-shaped hole 380f2 is more than twice the projected area of ​​the fourth arc-shaped component 240f2, so that the fourth arc-shaped component 240f2 can rotate within the fifth arc-shaped hole 380f2.

[0149] More specifically, the number of limiting protrusions 240f3 is less than the number of limiting grooves 380f3, so that when the four arc-shaped parts 240f2 rotate in the fifth arc-shaped hole 380f2, the inner shell can be freely limited by 15 to 135 degrees through the cooperation of the limiting protrusions 240f3 and the limiting grooves 380f3.

[0150] In another specific embodiment, the limiting protrusion 240f3 on the sixth fixing part 240f can be set as a groove, and the limiting groove 380f3 on the sixth matching part 380f can be set as a protrusion, so that when the four arc-shaped parts 240f2 rotate in the fifth arc-shaped hole 380f2, the inner shell can be freely limited by 15 to 135 degrees through the cooperation of the protrusion and the groove.

[0151] Therefore, it can be concluded that the pen packaging box provided by this patent has the following advantages over the prior art: (1) The pen packaging box provided by this patent is highly innovative and has a unique shape. When the pen packaging box is opened, it is X-shaped and can be placed on a table or other flat surface. It has high stability and makes it easy for users to identify pens.

[0152] (2) By leaving gaps on both sides of the inner shell and combining them with the appropriate spacing between the internal mesh components, a pen storage area is formed that makes it easy for fingers to reach in to pick up or put down the pen, which significantly improves the convenience of picking up and putting down the pen and the user experience.

[0153] (3) By setting a grid inside the inner shell corresponding to the middle section of the pen barrel, lateral support and constraint can be provided in the middle of the pen, thereby effectively limiting the movement of the pen in all directions inside the pen packaging box, preventing it from shaking, colliding with each other, shifting its position or tipping over during transportation and carrying, and ensuring that each pen can be firmly held in its predetermined position. At the same time, the grid can be flexibly configured and arranged according to different pen types or different specifications to meet the needs of various pen combinations.

[0154] (4) The flexible carrying strap makes it easy for users to carry. For direct-liquid ink pens, the strap is parallel to the pen's axis, ensuring the packaging remains horizontal during transport. This design addresses the physical limitation of direct-liquid ink pens, preventing ink backflow or leakage when the pen is placed vertically with the nib facing down, or ink backflow due to gravity when the nib is placed vertically with the nib facing up, which could affect ink flow after initial use or prolonged storage. For non-direct-liquid ink pens, the carrying strap can be perpendicular to the pen's axis. This unique packaging design also effectively showcases the brand image and stimulates consumer purchasing desire.
