Description

Technical Field

[0001] This utility model relates to the field of packaging technology, and in particular to a paper box component and an environmentally friendly paper box. Background Technology

[0002] In the current packaging industry, paper bags are a common form of packaging, widely used in shopping, gift packaging, and other scenarios. Traditional paper bags have a relatively simple function, primarily focusing on containing items, and are significantly inadequate in terms of product display and transportation protection. Ordinary paper bags typically only have a simple bag body and carrying straps, failing to meet the needs of merchants for multi-angle, clear display of goods, and making it difficult for consumers to intuitively understand the features and details of the products inside. Furthermore, during transportation, the lack of effective securing and protection measures makes the items inside easily damaged by shaking and collisions, especially fragile items, handicrafts, or precision instruments, where this risk is even more pronounced.

[0003] A search revealed Chinese Patent Publication No. CN221024760U, which discloses an environmentally friendly cardboard box. The box includes a main body with a cavity for holding items. A hook with a hole is provided on the main body. Both the main body and the hook are made of paper. This utility model also discloses a cardboard box assembly, including a sleeve and an environmentally friendly cardboard box. The sleeve has a cavity for holding the main body, which is fitted onto the outer periphery of the main body to close the cavity. The sleeve has a positioning through-hole corresponding to the hook, formed by one end of the cavity penetrating one end face of the sleeve. The sleeve also has an installation opening, formed by the other end of the cavity penetrating the other end face of the sleeve. This utility model is not only environmentally friendly but also helps reduce packaging costs.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: The devices lack a three-dimensional display structure design, failing to achieve multi-angle visual presentation of goods and thus failing to meet the product display needs of modern consumer scenarios. The lack of internal support and item securing devices makes items susceptible to damage from shaking during transportation; the paper sleeve's fit with the main body only provides simple sealing, lacking a dynamic cushioning protection mechanism. The packaging structure focuses on basic containment, lacking integrated practical functional modules such as handles and display windows, requiring additional accessories for carrying and display, increasing packaging complexity and cost. Utility Model Content

[0005] To overcome the technical defects of existing technologies, this utility model provides a paper box assembly and an environmentally friendly paper box.

[0006] The technical solution adopted by this utility model is: a paper box assembly and an environmentally friendly paper box, including a paper bag, wherein the side wall of the paper bag is provided with pre-pressed creases, a carrying strap is fixedly installed on the top opening edge of the paper bag, transparent sheets are fixedly connected to the inner walls of the left and right sides of the paper bag, and a display frame assembly is provided in the internal cavity of the paper bag.

[0007] A display frame assembly includes a first display frame and a second display frame, arranged in a staggered and symmetrical manner. Each display frame includes a slanted triangular paper holder, a hollow slot, a first locking block, and a second locking block. The slanted triangular paper holder is disposed within the inner cavity of a paper bag. A through hollow slot is formed in the center of the slanted triangular paper holder. A first locking block is fixedly connected to the left side of the slanted triangular paper holder, and a second locking block is fixedly connected to the right side of the slanted triangular paper holder. The facing surfaces of the first and second locking blocks each have mating slots. The staggered and symmetrical design of the display frame assembly improves structural stability and the versatility of the display.

[0008] Preferably, the display frame assembly further includes a main positioning frame, reinforcing ribs, and a crossbar. The main positioning frame is slidably fitted into the inner cavity of the paper bag. Several parallel reinforcing ribs are fixedly connected to the front sidewall of the main positioning frame, and the ends of the reinforcing ribs are all fixedly connected to a laterally extending crossbar. The reinforcing ribs and the crossbar together form a trapezoidal support frame. The design of the main positioning frame and reinforcing ribs further enhances the stability and load-bearing capacity of the display frame.

[0009] Preferably, the tilt direction of the slanted triangular paper holder in the first display frame is mirror-symmetrical to the tilt direction of the slanted triangular paper holder in the second display frame. This mirror-symmetrical slanted triangular paper holder design makes the display frame components more stable and facilitates the display of items.

[0010] Preferably, the transparent sheet is positioned to correspond to the inclined surface of the triangular paper holder, forming a display window. This correspondence between the transparent sheet and the triangular paper holder makes the display window clearer and facilitates observation of the displayed items.

[0011] Preferably, the sum of the thickness values ​​of the inclined triangular paper holders of the first display frame and the second display frame is equal to the thickness of the inner cavity of the paper bag. The thickness design of the inclined triangular paper holders ensures a perfect fit between the display frame assembly and the inner cavity of the paper bag, improving the overall structural stability.

[0012] Preferably, the bottom of the main positioning frame is provided with a sliding track structure that cooperates with the inner wall of the paper bag. The sliding track structure includes at least two sets of parallel guide ridges. The design of the sliding track structure makes the sliding of the main positioning frame in the inner cavity of the paper bag smoother, and facilitates the adjustment of the position of the display frame.

[0013] Preferably, the engaging surfaces of the first and second card blocks are provided with card slots, the depth of which is 2-5mm. This depth design of the card slots makes the engagement of the first and second card blocks more secure, improving the stability of the display frame assembly.

[0014] Preferably, the surface of the crossbar is covered with a cushioning layer made of foamed polyethylene material with a thickness of 1-3 mm. The cushioning layer design reduces friction between the crossbar and the inner wall of the paper bag, extending its service life.

[0015] The beneficial effects of this utility model are as follows: By setting up a first display frame, a second display frame, and a slanted triangular paper holder as components of the display frame assembly, and through the structural cooperation between the slanted triangular paper holder and the hollow groove, the display frame assembly can form a three-dimensional display window through the inclined surface of the slanted triangular paper holder and the transparent sheet. This achieves the effect of multi-angle three-dimensional display of selected goods through a staggered and symmetrically arranged double display structure. This design, through the mirror-symmetrical inclined layout of the slanted triangular paper holder, combined with a sliding main positioning frame, realizes modular expansion of the display space, effectively improving the space utilization and visual appeal of the product display. By setting up a first locking block, a second locking block, and a buffer layer, and through the synergistic cooperation between the locking structure and the buffer layer, the display frame assembly can precisely limit the position of goods through the 2-5mm deep locking grooves. Simultaneously, the foamed polyethylene buffer layer provides shockproof protection for the carried items, thus achieving the effect of stable carrying and transportation of selected fragile items through a double protective structure. This design, through the combination of the sliding track structure of the main positioning frame and the trapezoidal support frame, not only ensures the dynamic adjustability of the display structure, but also enhances the overall load-bearing capacity through the combination of reinforcing ribs and crossbars, thus achieving an optimized balance between display function and practical performance.

[0022] The present invention will be further described below with reference to the accompanying drawings:

[0023] like Figures 1 to 5 As shown, this embodiment provides a paper box assembly and an environmentally friendly paper box, including a paper bag 1. The side wall of the paper bag 1 is provided with a pre-pressed crease 2. A carrying strap 3 is fixedly installed on the top opening edge of the paper bag 1. Transparent sheets 5 are fixedly connected to the inner walls of the left and right sides of the paper bag 1. A display frame assembly 4 is provided in the internal cavity of the paper bag 1.

[0024] The display frame assembly 4 includes a first display frame 41 and a second display frame 42, arranged in a staggered and symmetrical manner. Both the first and second display frames include a triangular paper holder 403, a hollow slot 405, a first locking block 406, and a second locking block 407. The triangular paper holder 403 is disposed within the inner cavity of the paper bag 1. A through hollow slot 405 is formed in the center of the triangular paper holder 403. The first locking block 406 is fixedly connected to the left side of the triangular paper holder 403, and the second locking block 407 is fixedly connected to the right side. Both the first and second locking blocks 406 have mating slots on their facing surfaces. The design of the display frame assembly 4 effectively separates and secures the displayed items inside the paper bag 1, preventing movement or damage during transportation. The hollow slot 405 of the triangular paper holder 403 not only reduces the overall weight but also facilitates air circulation, making it suitable for displaying items requiring ventilation. The matching slot design of the first card block 406 and the second card block 407 allows the display frame component 4 to be quickly assembled and disassembled, improving the flexibility of use.

[0025] The display frame assembly 4 also includes a main positioning frame 401, reinforcing ribs 402, and a crossbar 404. The main positioning frame 401 is slidably fitted into the inner cavity of the paper bag 1. Several parallel reinforcing ribs 402 are fixedly connected to the front side wall of the main positioning frame 401. The ends of the reinforcing ribs 402 are all fixedly connected to a laterally extending crossbar 404. The reinforcing ribs 402 and the crossbar 404 together form a trapezoidal support frame. The sliding design of the main positioning frame 401 allows the display frame assembly 4 to be adjusted as needed to accommodate display items of different sizes. The trapezoidal support frame formed by the reinforcing ribs 402 and the crossbar 404 enhances the structural strength of the display frame assembly 4, ensuring that it is not easily deformed or damaged when bearing heavy objects.

[0026] The tilt direction of the triangular paper holder 403 in the first display frame 41 is mirror-symmetrical to the tilt direction of the triangular paper holder 403 in the second display frame 42. This symmetrical arrangement is not only aesthetically pleasing, but also ensures that the display frame assembly 4 is subjected to uniform force when carrying items, thus improving overall stability.

[0027] The transparent sheet 5 is installed in a position corresponding to the inclined surface of the triangular paper holder 403, forming a display window for the items. The corresponding arrangement of the transparent sheet 5 and the triangular paper holder 403 allows the displayed items to be observed from multiple angles, enhancing the display effect and making it particularly suitable for retail and exhibition occasions.

[0028] The sum of the thickness values ​​of the triangular paper holder 403 of the first display frame 41 and the triangular paper holder 403 of the second display frame 42 equals the thickness of the inner cavity of the paper bag 1. This precise dimensional matching ensures the stable installation of the display frame assembly 4 inside the paper bag 1, preventing shaking or falling off due to size mismatch.

[0029] The bottom of the main positioning frame 401 is provided with a sliding track structure that cooperates with the inner wall of the paper bag 1. The sliding track structure includes at least two sets of parallel guide ridges. The design of the sliding track structure allows the main positioning frame 401 to slide smoothly inside the paper bag 1, making it convenient for users to adjust the position of the display frame component 4 as needed.

[0030] The first locking block 406 and the second locking block 407 have locking grooves on their locking surfaces, with a depth of 2-5mm. The depth design of the locking grooves ensures the stability of the first locking block 406 and the second locking block 407 when they are locked together, preventing the display frame component 4 from loosening or falling off due to poor locking.

[0031] The surface of the crossbar 404 is covered with a cushioning layer made of foamed polyethylene material with a thickness of 1-3mm. The cushioning layer not only increases the comfort of the crossbar 404, but also plays a role in anti-slip and shock absorption, making it particularly suitable for carrying fragile or valuable items.
