Description

Technical Field

[0001] This utility model relates to a paper box; in particular, it relates to an innovative paper box structure with a reinforced plastic ring frame. Background Technology

[0002] Packaging boxes are undoubtedly an important part of product marketing, especially for social groups that value "gift-giving," where packaging boxes play a crucial role in whether people will buy a product.

[0003] This utility model mainly discusses paper packaging boxes (i.e., cardboard boxes). Traditional paper packaging boxes are usually designed in square, rectangular, heart-shaped, or oval shapes. This is mainly because these simple geometric shapes are easy to manufacture, have low production costs, and are highly efficient. However, the disadvantage is that they sacrifice the potential advantages of brand visual recognition and consumer appeal. These simple geometric shapes not only restrict the designer's imagination but also directly affect the product's differentiation in the market. In a highly competitive environment, packaging that perfectly fits the product's shape and is even artistic in itself can often immediately catch the consumer's attention and convey a higher product value.

[0004] However, packaging boxes currently face significant challenges in shaping irregular contours, and even when they are managed to be formed, there is a challenge of insufficient structural strength. This makes it difficult for the industry to achieve more creative packaging designs that match the unique lines of the product. Utility Model Content

[0005] The main objective of this invention is to provide a paper box structure with a reinforced plastic ring frame.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: The paper box includes a box body and a lid, wherein the lid can fit and cover the box body. Both the box body and the lid include a base plate and a ring frame. The ring frame is vertically arranged around the periphery of the base plate, and the ring frame has a rolled end and a folded end along the vertical direction. The folded end extends inward to form an inner lining wall. The inner lining wall and the ring frame are in a surface-fitting relationship. An interlocking slot is provided between the end of the inner lining wall and the rolled end for the periphery of the base plate to be inserted, and it is fixed by adhesive. The ring frame must include at least one continuous curved profile section, which includes a plurality of continuously arranged concave edges and convex edges.

[0007] The main effect and advantage of this utility model is that it can provide users with a more diverse and richer paper box structure, allowing designers to unleash their imagination and thus greatly enhance the competitive advantage of paper box products in the market. Furthermore, the ring frame has the morphological features of rolled end, folded end and inner lining wall, which can greatly strengthen the structural support strength of the ring frame, so that the paper box has both aesthetic value and strength.

[0022] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 The diagram shows a preferred embodiment of the paper box structure with a reinforced plastic ring frame according to the present invention. However, these embodiments are for illustrative purposes only and are not limited to this structure in patent applications.

[0023] The paper box 100 includes a box body 10a and a cover 10b, wherein the cover 10b can fit and close to the box body 10a. Both the box body 10a and the cover 10b include a base plate 11 and a shaping frame 12. The shaping frame 12 is vertically arranged around the periphery of the base plate 11, and the shaping frame 12 has a rolled end 125 and a folded end 126 along the vertical direction. The folded end 126 extends inward to form an inner lining wall 127. The inner lining wall 127 and the shaping frame 12 are in a surface-fitting relationship. A slot 20 is provided between the end of the inner lining wall 127 and the rolled end 125 for embedding around the periphery of the base plate 11 and is fixed by an adhesive 30. The shaping frame 12 must include at least a continuously curved profile section 40, which includes a plurality of continuously arranged concave edges 41 and convex edges 42.

[0024] like Figure 2 , Figure 3 As shown, in this example, a reinforcing liner 50 is overlaid on the inner side of the substrate 11, and the periphery of the reinforcing liner 50 is perpendicular to the inner side of the inner liner wall 127. The main advantage of the reinforcing liner 50 shown in this example is that it reinforces the deficiencies of the substrate 11 and can cover the excess adhesive 30, thus achieving a neat finishing effect.

[0025] Among them, such as Figures 5 to 7 As shown, the irregularly shaped ring frame 12 forms a mimicry shape, thereby defining a body region a1, a head region a2, and multiple foot regions a3. Each of the aforementioned regions is defined by the orthogonal position of its longest axis L1 and shortest axis L2, which respectively defines a body center point c1, a head center point c2, and multiple foot center points c3. The body center point c1, the head center point c2, and the multiple foot center points c3 are staggered from each other. Furthermore, the body region a1, the head region a2, and the multiple foot regions a3 are all formed by continuous curved contour segments 40 to create the contour shape of the mimicry shape.

[0026] The mimicry includes mimicry of any one of the following: animals (such as...) Figures 5 to 9 As shown, this includes animals such as cows, sheep, horses, bears, and dogs; human figures; mythological figures (such as gods, Buddhas, and Nezha); mythical beasts (such as dragons, phoenixes, Vermilion Birds, Black Tortoises, Azure Dragons, White Tigers, turtles, and Qilin); anime characters (such as Mickey Mouse and Pikachu); and virtual characters or mascots.

[0027] like Figures 5 to 7 As shown, in this example, one side of the body region a1 also includes a relatively protruding tail region a4.

[0028] The overall outline of the ring frame can also be any of the following shapes: an island (such as...) Figure 1 , Figure 2 The shape shown is Taiwan-shaped, cloud-shaped, or heart-shaped (as shown). Figure 9 (As shown).

[0029] This utility model has a paper box structure with a reinforced plastic ring frame, and its manufacturing method includes: (a) Prepare a substrate 11, the substrate 11 having a shaped outline around its perimeter; (b) Prepare a ring frame 12, such as Figure 10 As shown, the ring frame 12 is unfolded into an elongated shape to define a long lateral X and a short lateral Y. The long lateral X forms a first end 121 and a second end 122 that are relatively far apart, and the short lateral Y includes a first side 123 and a second side 124. (c) Using a first die-cutting forming method 60, a folded-back end 126 is formed on the first side 123 of the ring frame 12, and the folded-back end 126 extends inward to form an inner lining wall 127, the inner lining wall 127 being in a planar abutment relationship with the ring frame 12; (e.g.) Figure 10 (As shown) (d) Using a second die-cutting forming means 70, a rolled end 125 is formed on the second side 124 of the ring frame 12, and a snap-fit ​​seam 20 is left between the end of the inner lining wall and the rolled end. (e) Fix the first end 121 and the second end 122 of the ring frame 12 together (e.g.) Figure 10 (as shown in the bottom diagram), so that the ring frame 12 changes from an expanded state to a closed ring state; (f) Using an internal and external mold shaping method 80 (such as...) Figure 11 As shown), to bend and shape the ring frame 12: an inner mold 81 and an outer mold 82 are set according to the shape contour of the periphery of the substrate 11. A molding gap 83 is reserved between the inner mold 81 and the outer mold 82. The width of the molding gap 83 is just enough for the ring frame 12 to be fitted in. Then, a pressure means 84 (such as...) is applied to the inner mold 81. Figure 11 The bottom image and Figure 12 (as shown in a) to shape the ring frame 12 into the molding gap 83; (g) With the inner mold 81 removed, an adhesive 30 is applied to the seam using an adhesive method 90; (e.g.) Figure 12 (as shown in b) (h) Place the substrate 11 into the ring frame 12 until the substrate 11 is embedded in the locking slot 20 of the ring frame 12 (e.g., Figure 12 (as shown in c), and can simultaneously adhere and fix the substrate 11 and the ring frame 12 by adhesive 30; and (i), such as Figure 13 As shown, the substrate 11 and the ring frame 12 that are glued and fixed are removed from the outer mold 82.

[0030] The term "die cutting" used above is a technical term referring to the processing technology of cutting materials into predetermined shapes, commonly known as "digging" in Taiwan. Simply put, it involves using a pre-made die to quickly and precisely press and cut paper (or other materials) into a preset shape, including folding, curling, half-cutting, or punching.

[0031] The inner mold 81 is a multi-point adjustable support mold / die, which includes a number of individually operable support units, array-type push rods, or expandable flexible units, thereby enabling it to perform pressurization and expand and compress towards the outer mold, so that the ring frame 12 is shaped in the molding gap 83.

[0032] The first end 121 of the ring frame 12 is defined by a gap 128 formed between the inner lining wall 127 and the ring frame 12, while the second end 122 forms a protruding insert 129 (e.g., Figure 10 As shown), the first end 121 and the second end 122 are fixed together by inserting the insert 129 into the gap 128.

[0033] Through the aforementioned structural composition and technical features, this utility model possesses a reinforced plastic ring frame cardboard box structure. Its practical application benefits primarily lie in providing users with a more diverse and richer cardboard box structure, allowing designers' imaginations to run wild and enabling the creation of various previously unseen contour forms, such as the various mimicry listed above (please refer to...). Figure 1 , Figures 5 to 9 This significantly enhances the competitive advantage of paper box products in the market, and its ring frame 12 has the morphological characteristics of a rolled end 125, a folded end 126, and an inner lining wall 127 (such as...). Figure 4 As shown), it can further enhance the structural support strength of the ring frame 12, so that the cardboard box has both aesthetic value and strength.

[0034] For example Figure 14 As shown, the base plate 11 of the box body 10a and the cover body 10b can also be provided with corresponding holes 13 for the carrying strap 14 to be threaded through, thereby providing the user with another way to carry the box.

[0035] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
