[0002] Fascia guns are precision small appliances, and their packaging must protect against drops, vibrations, and stacking. Currently, the industry commonly uses EPS (polystyrene foam) inserts, which have the advantages of low cost and good resilience. However, EPS is non-degradable, and its use is restricted by legislation in European and American markets, and exports face high environmental taxes.

[0003] Paper-plastic (molded pulp) is considered the best alternative to EPS due to its renewable, compostable, and fully recyclable properties. However, most existing paper-plastic packaging structures rely on adding reinforcing ribs to provide cushioning, which can only withstand partial external forces during transportation and handling, failing to fully protect the fascia gun product and potentially causing damage.

[0025] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0026] Please refer to Figures 1 to 3 A paper-plastic packaging structure for a fascia gun includes a paper-plastic outer shell 1, a first inner shell 2, and a second inner shell 3. The paper-plastic outer shell 1 has a first folding portion 11 and a second folding portion 12 that can be folded and connected. The first inner shell 2 is disposed inside the first folding portion 11 and has a first conforming portion 21, forming a first buffer cavity 111 between the first conforming portion 21 and the first folding portion 11. The second inner shell 3 is disposed inside the second folding portion 12 and has a second conforming portion 31, forming a second buffer cavity 121 between the second conforming portion 31 and the second folding portion 12. When the first folding portion 11 and the second folding portion 12 are folded together, the first conforming portion 21 and the second conforming portion 31 are combined with each other and used to fix the fascia gun.

[0027] As can be seen from the above description, the beneficial effects of this utility model are as follows: the paper-plastic outer shell 1 is folded by the first folding part 11 and the second folding part 12 which are foldable and connected. The first buffer cavity 111 formed between the first conforming part 21 of the first inner shell 2 and the first folding part 11, and the second buffer cavity 121 formed between the second conforming part 31 of the second inner shell 3 and the second folding part 12, together constitute a multi-level buffer space after folding. The first conforming part 21 and the second conforming part 31 are combined with each other to achieve full-circumference zero-gap fixation of the fascia gun, thereby replacing EPS and overcoming the shortcomings of the existing paper-plastic reinforcing rib structure that cannot completely protect the fascia gun in the event of drop or vibration.

[0028] Furthermore, the first folding portion 11 is provided with a snap-fit ​​protrusion 114, and the second folding portion 12 is provided with a snap-fit ​​groove 124 that engages with the snap-fit ​​protrusion 114; or, the second folding portion 12 is provided with a snap-fit ​​protrusion 114, and the first folding portion 11 is provided with a snap-fit ​​groove 124 that engages with the snap-fit ​​protrusion 114.

[0029] As described above, the snap-fit ​​engagement between the snap-fit ​​protrusion 114 and the snap-fit ​​groove 124 keeps the first fold 11 and the second fold 12 locked after folding, preventing the folds from opening due to vibration or drops during transportation, maintaining the integrity of the buffer cavity, and avoiding damage to the product due to loose packaging.

[0030] Furthermore, the number of the snap-fit ​​protrusions 114 is equal to the number of the snap-fit ​​grooves 124, and both are multiple.

[0031] As described above, the multiple snap-fit ​​protrusions 114 and multiple snap-fit ​​grooves 124 correspond one-to-one, which disperses the locking force, avoids stress concentration at a single point that could cause the paper and plastic to break, and improves the overall locking reliability.

[0032] Furthermore, the first folding portion 11 has a first gripping hole 112, and the second folding portion 12 has a second gripping hole 122 with the same shape as the first gripping hole 112. When the first folding portion 11 and the second folding portion 12 are folded together, the first gripping hole 112 and the second gripping hole 122 correspond to each other.

[0033] As described above, the first gripping hole 112 and the second gripping hole 122 are connected after folding to form a through gripping channel, which makes it easy to insert fingers to pick up the entire package at once and reduce the risk of falling due to unstable grip during handling.

[0034] Furthermore, both the first gripping hole 112 and the second gripping hole 122 are elongated.

[0035] As described above, the elongated first gripping hole 112 and second gripping hole 122 provide sufficient finger insertion length, reduce local pressure, prevent local tearing of paper and plastic during gripping, and ensure the integrity of the packaging during handling.

[0036] Furthermore, the outer side of the first folding portion 11 is provided with a first protruding ring 113 surrounding the first gripping hole 112, and / or the outer side of the second folding portion 12 is provided with a second protruding ring 123 surrounding the second gripping hole 122.

[0037] As described above, the first convex ring 113 surrounds the first gripping hole 112 and / or the second convex ring 123 surrounds the second gripping hole 122, increasing the wall thickness at the edge of the hole, reducing the concentration of gripping stress, and preventing cracking at the edge of the hole.

[0038] Furthermore, the inner and / or outer sides of the first folded portion 11 are provided with a first reinforcing rib.

[0039] As can be seen from the above description, the first reinforcing rib is provided on the inner and / or outer side of the first folding part 11 to improve the bending stiffness of the first folding part 11 itself, reduce deformation during folding or stacking, and prevent the buffer cavity from failing due to the deformation of the paper-plastic shell 1.

[0040] Furthermore, the inner and / or outer sides of the second folded portion 12 are provided with a second reinforcing rib.

[0041] As described above, the second reinforcing rib is provided on the inner and / or outer side of the second folding part 12 to improve the bending stiffness of the second folding part 12 itself, reduce deformation during folding or stacking, and prevent the buffer cavity from failing due to the deformation of the paper-plastic shell 1.

[0042] Furthermore, the first buffer cavity 111 and / or the second buffer cavity 121 have a buffer filling material.

[0043] As described above, the buffer filler is placed in the first buffer cavity 111 and / or the second buffer cavity 121, which increases the energy absorption path, makes up for the shortcomings of existing paper-plastic composites that rely solely on reinforcing ribs for cushioning, and improves the protection against drops and vibrations.

[0044] Furthermore, the first conforming portion 21 and / or the second conforming portion 31 have a varnish coating.

[0045] As described above, the varnish coating covers the surface of the first conformal part 21 and / or the second conformal part 31, reducing the coefficient of friction and blocking moisture, maintaining the dimensional stability of the conformal part and avoiding scratching the surface of the fascia gun, thus solving the problem of decreased cushioning performance of the reinforcing ribs after the paper-plastic softens due to moisture absorption.

[0046] Please refer to Figures 1 to 3Embodiment 1 of this utility model is: a paper-plastic packaging structure for a fascia gun. In situations where environmentally friendly single-material paper is needed to replace EPS for fascia gun packaging, the folded paper-plastic outer shell 1, combined with a double-buffered cavity and a conformal part, provides drop, vibration, and stacking protection for the fascia gun, and meets the requirements of flat storage and transportation. Specifically, the paper-plastic packaging structure for the fascia gun includes a paper-plastic outer shell 1, a first inner shell 2, and a second inner shell 3. The paper-plastic outer shell 1 has a first folding part 11 and a second folding part 12 that can be folded and connected. The first inner shell 2 is located inside the first folding part 11 and has a first conformal part 21, forming a first buffered cavity 111 between the first conformal part 21 and the first folding part 11. The second inner shell 3 is located inside the second folding part 12 and has a second conformal part 31, which is connected to the first inner shell 12. A second buffer cavity 121 is formed between the second folding portions 12. When the first folding portion 11 and the second folding portion 12 are folded together, the first conforming portion 21 and the second conforming portion 31 are combined with each other and used to fix the fascia gun. The paper-plastic shell 1 is folded by the first folding portion 11 and the second folding portion 12 that can be folded together. The first buffer cavity 111 formed between the first conforming portion 21 and the first folding portion 11 of the first inner shell 2 and the second buffer cavity 121 formed between the second conforming portion 31 and the second folding portion 12 of the second inner shell 3 together constitute a multi-level buffer space after folding. After the first conforming portion 21 and the second conforming portion 31 are combined with each other, the fascia gun is fixed with zero gap around the entire circumference, thereby replacing EPS and overcoming the shortcomings of the existing paper-plastic reinforcing rib structure that cannot completely protect the fascia gun in the event of drop or vibration.

[0047] It should be noted that the outer shell 1, the first inner shell 2, and the second inner shell 3 are all made of paper-plastic material. Paper-plastic material (molded pulp) is a rigid paper material obtained by making pulp from waste paper or virgin plant fibers, followed by vacuum filtration, hot pressing (or drying) and molding. It belongs to the category of "single paper base" and can be recycled and pulped together with ordinary cardboard boxes. It has the environmentally friendly attributes of being renewable, compostable, and fully recyclable. At the same time, different strengths can be obtained by adjusting the fiber ratio, wall thickness, and rib structure. It is often used to replace non-degradable foam inner supports such as EPS and EPE.

[0048] Specifically, the first conforming part 21 and the second conforming part 31 are conforming grooves whose shapes are adapted to the shape of the fascia gun body and the shape of the fascia gun accessories. The specific shape of the conforming groove can be set according to the shape of the fascia gun body and the shape of the fascia gun accessories, which will not be discussed in detail here.

[0049] In this embodiment, the first folding portion 11 is provided with a snap-fit ​​protrusion 114, and the second folding portion 12 is provided with a snap-fit ​​groove 124 that engages with the snap-fit ​​protrusion 114. It can be understood that the snap-fit ​​between the snap-fit ​​protrusion 114 and the snap-fit ​​groove 124 keeps the first folding portion 11 and the second folding portion 12 locked after folding, preventing the folding portion from opening due to vibration or drops during transportation, maintaining the integrity of the buffer cavity, and avoiding damage to the product due to loose packaging. Of course, in some other embodiments, a snap-fit ​​protrusion 114 may also be provided on the second folding portion 12, and the first... The folding part 11 is provided with a locking groove 124 that engages with the locking protrusion 114. Specifically, the position of the locking protrusion 114, the position of the locking groove 124, the number of locking grooves 124, and the number of locking protrusions 114 can be set according to actual application requirements. In this embodiment, the number of locking protrusions 114 is equal to the number of locking grooves 124, and both are multiple. Multiple locking protrusions 114 and multiple locking grooves 124 are matched one-to-one, so that the locking force is dispersed, avoiding single-point stress concentration that could cause paper-plastic breakage, and improving the overall locking reliability.

[0050] For the best option, please refer to the following: Figure 1 and Figure 2 The first folding portion 11 has a first gripping hole 112, and the second folding portion 12 has a second gripping hole 122 with the same shape as the first gripping hole 112. When the first folding portion 11 and the second folding portion 12 are folded together, the first gripping hole 112 and the second gripping hole 122 correspond to each other. The first gripping hole 112 and the second gripping hole 122 are connected after folding to form a through gripping channel, which facilitates the insertion of fingers to lift the entire package at once and reduces the risk of falling due to unstable grip during handling. Specifically, in this embodiment, the shape of the first gripping hole 112 and the shape of the second gripping hole 122 are both elongated. The elongated shape of the first gripping hole 112 and the second gripping hole 122 provides sufficient finger insertion length, reduces local pressure, avoids local tearing of paper and plastic during gripping, and ensures the integrity of the package during handling.

[0051] In addition, in some other embodiments, the shape of the first gripping hole 112 and the shape of the second gripping hole 122 can also be rectangular, circular, elliptical, trapezoidal, etc., which can be set according to the actual application requirements, and will not be described in detail here.

[0052] Optionally, the outer side of the first folding portion 11 is provided with a first protruding ring 113 surrounding the first gripping hole 112, and / or the outer side of the second folding portion 12 is provided with a second protruding ring 123 surrounding the second gripping hole 122. This increases the wall thickness of the gripping hole edge, reduces gripping stress concentration, and prevents the hole edge from cracking.

[0053] In some other embodiments, a first reinforcing rib is provided on the inner and / or outer sides of the first folding portion 11. The first reinforcing rib, located on the inner and / or outer sides of the first folding portion 11, increases the bending stiffness of the first folding portion 11 itself, reduces deformation during folding or stacking, and prevents the buffer cavity from failing due to deformation of the paper-plastic outer shell 1. Furthermore, a second reinforcing rib can also be provided on the inner and / or outer sides of the second folding portion 12. This increases the bending stiffness of the second folding portion 12 itself, reduces deformation during folding or stacking, and prevents the buffer cavity from failing due to deformation of the paper-plastic outer shell 1.

[0054] Optionally, the first buffer cavity 111 and / or the second buffer cavity 121 may have a buffer filler. The buffer filler, placed within the first buffer cavity 111 and / or the second buffer cavity 121, increases the energy absorption path, compensates for the shortcomings of existing paper-plastic composites that rely solely on reinforcing ribs for cushioning, and improves protection against drops and vibrations. Specifically, the buffer filler may be made of compostable pulp or honeycomb paper of the same material as the paper-plastic composite, filled simultaneously during molding or fixed online by spraying adhesive, forming a paper-based buffer layer integral with the cavity wall. This maintains the recyclability of the single paper base while increasing the energy absorption path and improving drop cushioning performance.

[0055] Preferably, the first conformal portion 21 and / or the second conformal portion 31 have a varnish coating. The varnish coating covers the surface of the first conformal portion 21 and / or the second conformal portion 31, reducing the coefficient of friction and blocking moisture, maintaining the dimensional stability of the conformal portion and preventing scratches on the fascia gun surface, thus solving the problem of decreased cushioning performance of the reinforcing ribs after the paper-plastic softens due to moisture absorption. Specifically, the varnish coating uses water-based transparent ink, which forms a continuous film of 0.8–1.2 μm after the first conformal portion 21 and / or the second conformal portion 31 is formed by online spraying or roller coating. After curing, it reduces the surface coefficient of friction and blocks moisture, maintains the dimensional stability of the conformal portion and prevents scratches on the fascia gun shell. At the same time, the coating and the paper-plastic are both fiber substrates, and they are dispersed together with the shell during recycling and pulping, without damaging the single paper base properties.

[0056] In summary, the paper-plastic packaging structure of the fascia gun provided by this utility model has the characteristics of good cushioning performance. The paper-plastic shell is folded by a first folding part and a second folding part that can be folded and connected. The first buffer cavity formed between the first conforming part and the first folding part of the first inner shell and the second buffer cavity formed between the second conforming part and the second folding part of the second inner shell together constitute a multi-level buffer space after folding. The first conforming part and the second conforming part are combined to achieve full-circumference zero-gap fixation of the fascia gun, thereby replacing EPS and overcoming the shortcomings of the existing paper-plastic reinforcing rib structure that cannot completely protect the fascia gun in the event of drop or vibration.

[0057] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
