Technical Field

[0001] This utility model relates to the field of paper box technology, specifically a new type of reinforced paper packaging box. Background Technology

[0002] In the packaging industry, paper packaging boxes are widely used due to their biodegradability, low cost, and ease of processing. However, traditional paper packaging boxes are insufficient in terms of compression resistance and sealing, especially during logistics and transportation, where they are easily squeezed, leading to deformation or even damage, affecting the safety of the contents. Furthermore, traditional paper packaging boxes are relatively monotonous in appearance, lacking aesthetics and personalization, making it difficult to meet the market's demand for high-quality packaging.

[0003] To address these issues, a series of reinforced paper packaging boxes have emerged on the market. However, these products often focus only on improving compression resistance, neglecting the decorative and convenient aspects of packaging. Therefore, developing a new type of reinforced paper packaging box that possesses both excellent compression resistance and good decorative effects, along with convenient sealing functionality, is particularly important.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This utility model proposes a novel reinforced paper packaging box. By incorporating "L"-shaped plastic corner plates at the external corners of the carton, it effectively enhances the carton's compression resistance when stacked. The plastic corner plates not only distribute the stacking load but also increase friction with the carton and decorative paper sleeve through rubber pads within the notches, further improving the carton's stability. This design allows the carton to better resist compression and deformation during logistics transportation, protecting the contents. The decorative paper sleeve not only enhances the carton's aesthetics but also provides consumers with personalized options while providing protection for the carton. The decorative paper sleeve can be customized according to different market demands and consumer preferences, meeting diverse packaging needs. Simultaneously, the annular gap between the decorative paper sleeve and the carton adds a sense of layering to the packaging, enhancing the overall visual effect. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Please see Figures 1 to 5 This utility model provides a technical solution: a novel reinforced paper packaging box, including a carton 1. The top and bottom of the carton 1 are integrally formed with an inner sealing plate 2 and an outer sealing plate 3. There are two inner sealing plates 2, which are symmetrically distributed about the opening of the carton 1. There are two outer sealing plates 3 in each group, and the inner sealing plates 2 and outer sealing plates 3 are distributed alternately. The outer sealing plates 3 cover one side of the inner sealing plates 2. A decorative paper sleeve 5 is fitted on the outside of the carton 1. A plastic corner plate 4 is fixed to the inner wall of the decorative paper sleeve 5. The plastic corner plate 4 is fitted at the external corner of the carton 1. Adhesive tape 8 is glued to the surface of the outer sealing plate 3. Both ends of the adhesive tape 8 are glued to the outer wall of the decorative paper sleeve 5. The decorative paper sleeve 5 not only serves a decorative function, but also provides protection for the carton 1.

[0021] The decorative paper sleeve 5 is placed on the outside of the cardboard box 1. At this time, the plastic corner plate 4 is sandwiched between the cardboard box 1 and the decorative paper sleeve 5. When multiple cardboard boxes 1 are stacked, the plastic corner plate 4 improves the compression resistance of the cardboard box 1. That is, the load of the two stacked cardboard boxes 1 is concentrated on the plastic corner plate 4. After folding the inner sealing plate 2 at the bottom of the cardboard box 1 inward, the two outer sealing plates 3 at the bottom of the cardboard box 1 are also folded inward. Then, the two outer sealing plates 3 at the bottom of the cardboard box 1 are glued together with tape 8. Then, the items are put into the cardboard box 1 from the top opening of the cardboard box 1.

[0022] The height of the decorative paper sleeve 5 is equal to the height of the cardboard box 1. An annular gap is left between the decorative paper sleeve 5 and the cardboard box 1. The plastic corner plate 4 has an "L" shaped plate structure. The height of the plastic corner plate 4 is equal to the height of the decorative paper sleeve 5. There are four plastic corner plates 4, which are distributed at the four external corners of the cardboard box 1. A notch 6 is opened on the side of the plastic corner plate 4 near the cardboard box 1. A rubber gasket 7 is fixed on the surface of the notch 6. The thickness of the rubber gasket 7 is greater than the depth of the notch 6. There are two tapes 8. The two tapes 8 are connected to the two sets of outer sealing plates 3 respectively. Tape 9 is glued to the surface of the decorative paper sleeve 5. Tape 9 wraps around the two sets of outer sealing plates 3 and is glued to the outer sealing plates 3. There are two tapes 9. The two tapes 9 are distributed in parallel and are distributed in a cross pattern with tape 8.

[0023] After the contents of the cardboard box 1 are filled, fold the two inner sealing panels 2 at the top of the cardboard box 1 inward, then fold the two outer sealing panels 3 at the top of the cardboard box 1 inward. Then, attach tape 8 to the two outer sealing panels 3 at the top of the cardboard box 1, and attach both ends of tape 8 to the side panels on both sides of the cardboard box 1. Finally, attach tape 9 to the decorative paper sleeve 5 and wrap tape 9 around the decorative paper sleeve 5 and the outer sealing panels 3 to reinforce the connection between the two outer sealing panels 3 and seal the opening of the cardboard box 1.

[0024] The process for using the new reinforced paper packaging box is as follows:

[0025] Gently slip the decorative paper sleeve 5 onto the outside of the carton 1, ensuring that the decorative paper sleeve 5 matches the shape of the carton 1. During the slip-on process, confirm that the plastic corner plates 4 are correctly clamped at the external corners between the carton 1 and the decorative paper sleeve 5 to enhance the carton's compression resistance. Fold the two inner sealing panels 2 at the bottom of the carton 1 inwards so that they are flush with the bottom of the carton. Then, fold the two outer sealing panels 3 at the bottom of the carton 1 inwards as well, covering the inner sealing panels 2. Use two pieces of tape 8 to glue the edges of the two outer sealing panels 3 together, ensuring a secure bottom seal. Now that the bottom of the carton 1 is closed, you can put the items to be packaged into the top opening of the carton 1. When placing the items, be careful to avoid excessive compression or damage to the carton structure. After the items have been loaded, fold the two inner sealing panels 2 at the top of the carton 1 inwards. Then, fold the two outer sealing panels 3 at the top of the carton 1 inwards as well, covering the inner sealing panels 2. Using tape 8, glue the edges of the two outer sealing panels 3 together, ensuring that both ends of tape 8 are glued to the side panels on both sides of the carton 1 to enhance the sealing effect. Finally, using two pieces of tape 9, wrap them around the decorative paper sleeve 5 and the two outer sealing panels 3 at the top of the carton 1. Attach tape 9 to the decorative paper sleeve 5, ensuring it adheres tightly to the outer sealing panels 3 to further reinforce the carton's sealing structure. Tape 9 should be distributed crosswise with tape 8 to create additional fixing points and improve the overall stability of the carton.
