[0037] The utility model discloses an ammunition packaging box module to improve the wear resistance and waterproofness of ammunition packaging box.

[0038] The technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model and not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skilled in the art without creative work belong to the protection scope of the utility model.

[0039] In some embodiments, referring to Figures 1-2 The ammunition packaging box module provided by the utility model comprises packaging box units 1 and a second film layer 2. The packaging box units 1 are provided in plurality. It can be understood that the plurality in the application refers to two or more than two. The packaging box units 1 are stacked, that is, the packaging box units 1 are placed in turn in stack, and the stacking direction is not limited here, for example, the length direction, the height direction or the width direction of the packaging box unit 1. Each packaging box unit 1 comprises an ammunition packaging box 11 and a first film layer 12 covering the ammunition packaging box 11. The ammunition packaging box 11 is a main packaging structure for placing ammunition 3, and specifically comprises an outer box and an inner bracket arranged in the outer box. The specific structure of the ammunition packaging box 11 is not limited here. The single ammunition packaging box 11 is covered with the first film layer 12, that is, the single ammunition packaging box 11 is subjected to surface film coating treatment to form the first film layer 12 on the surface. The stacked plurality of packaging box units 1 is further covered with the second film layer 2, that is, the stacked plurality of packaging box units 1 is subjected to surface film coating treatment to form the second film layer 2 on the surface, and the material of the first film layer 12 is different from that of the second film layer 2.

[0040] The ammunition packaging box module provided by the utility model is characterized in that: firstly, the single-box ammunition packaging box 11 used for placing the ammunition 3 is coated with the first film layer 12 to form the packaging box monomer 1. The first film layer 12 is used to coat the ammunition packaging box 11 to improve the wear resistance of the ammunition packaging box 11, reduce the wear of the box corner, and improve the moisture-proof and dust-proof capacity of the ammunition 3. Then, the plurality of packaging box monomers 1 coated with the first film layer 12 are stacked, and the stacking direction can be along the length direction, the width direction or the height direction of the ammunition packaging box 11. The whole outer packaging box monomer 1 is coated with the second film layer 2 to form the ammunition packaging box module. The second film layer can enhance the whole packaging box monomer 1 to prevent wear and further improve the moisture-proof and dust-proof capacity. The first film layer 12 and the second film layer 2 are made of different materials, and the different properties of the two materials can facilitate the film coating and better prevent the ammunition 3 from being damaged by moisture and dust in the ammunition packaging box 11.

[0041] In some embodiments, the first film layer 12 is a polyvinyl chloride film (PVC film), and the second film layer 2 is a biaxially oriented polypropylene film (BOPP film). The PVC film can effectively protect the surface of the ammunition packaging box 11, prevent it from being affected by external environment such as moisture, grease and scratches, and help to improve the durability and service life of the ammunition packaging box 11. At the same time, the strength and stiffness of the coated ammunition packaging box 11 are improved, and it is not easy to be scratched, and it is more wear-resistant and corrosion-resistant. In addition, the PVC film also has good ultraviolet resistance and anti-aging performance. The BOPP film has good moisture-proof and waterproof performance, and has high tensile strength, impact strength, rigidity and toughness. In addition, it has good heat resistance and chemical stability, and has strong tensile strength and tear resistance. For the ammunition packaging box 11, due to the particularity of the products inside, there are special requirements for the film coating material, such as film coating temperature requirements. In this embodiment, the first film layer 12 is made of PVC film, and the second film layer 2 is made of BOPP film. The temperature required for film coating of the two can meet the storage temperature requirements of the ammunition 3, so that safe production can be realized. In addition, the PVC film as the film layer material of the single-box ammunition packaging box 11 can improve the strength and stiffness of the packaging box monomer 1, and facilitate the stacking of the plurality of packaging box monomers 1. The second film layer 2 is made of BOPP film, which has excellent barrier properties and heat sealing performance, so that the moisture-proof and waterproof performance of the whole ammunition packaging box module can be further improved.

[0042] In some embodiments, the ammunition packaging box 11 is a cuboid, and a plurality of ammunition packaging boxes 11 are stacked along the length direction of the cuboid, or stacked along the height direction of the cuboid, or stacked along the width direction of the cuboid. In one example, the plurality of ammunition packaging boxes 11 are stacked along the length direction of the cuboid, and the second film layer 2 is coated outside the combination of the overall packaging box monomer 1 formed by the stacking. In another example, the plurality of ammunition packaging boxes 11 are stacked along the width direction of the cuboid, and the second film layer 2 is coated outside the combination of the overall packaging box monomer 1 formed by the stacking. In still another example, the plurality of ammunition packaging boxes 11 are stacked along the height direction of the cuboid, and the second film layer 2 is coated outside the combination of the overall packaging box monomer 1 formed by the stacking. The second film layer 2 is coated outside the plurality of packaging box monomers 1 stacked in the same direction, and the overall shape of the combination of the plurality of packaging box monomers 1 is regular, which facilitates the coating of the film. In other embodiments, the plurality of packaging box monomers 1 can also be stacked in at least two of the height direction, the length direction and the width direction, and then the second film layer 2 is coated.

[0043] In some embodiments, the first film layer 12 covers the outer surface of the ammunition packaging box 11. It can be understood that the coverage here means that the first film layer 12 completely covers the outside of the ammunition packaging box 11, that is, the ammunition packaging box 11 is completely enclosed in the first film layer 12, which improves the protection effect of the first film layer 12.

[0044] In some embodiments, the second film layer 2 covers the outer surface of the overall combination of the plurality of packaging box monomers 1. It can be understood that the coverage here means that the second film layer 2 completely covers the outside of the combination of the overall packaging box monomers 1 formed by the stacking, that is, the combination of the overall packaging box monomers 1 formed by the stacking is completely enclosed in the second film layer 2, which improves the protection effect of the second film layer 2.

[0045] In some embodiments, the thickness of the first film layer 12 is greater than the thickness of the second film layer 2. The first film layer 12 serves as the outer surface structure of the ammunition packaging box, and its thickness is relatively thick to provide more reliable protection. At the same time, the thickness of the second film layer 2 is relatively thin, which provides protection while reducing space occupation, which is beneficial to the overall size of the ammunition packaging box module to facilitate the transportation of the ammunition packaging box module.

[0046] In some embodiments, the thickness of the first film layer 12 ranges from 0.025±0.002mm, and the thickness of the second film layer 2 ranges from 0.022±0.002mm. By setting the thickness of the first film layer 12 and the second film layer 2 within the above range, reliable protection can be provided while meeting the molding requirements, that is, the first film layer 12 and the second film layer 2 can be molded outside the corresponding ammunition packaging box and the combination of the stacked packaging box monomers.

[0047] In some embodiments, the heat seal strength of the first film layer 12 is ≥ 0.6 N / 15㎜, and the heat seal strength of the second film layer 2 is ≥ 2.0 N / 15㎜. The first film layer 12 and the second film layer 2 are made of film layers meeting the above requirements, ensuring the reliability of the film.

[0048] In some embodiments, referring to Figure 3 and Figure 4 , the ammunition packaging box 11 includes an outer box 111 and an inner holder 112. The inner holder 112 is arranged in the outer box 111, and the inner holder 112 includes a transverse partition plate 1121 and a longitudinal partition plate 1122. It can be understood that the transverse partition plate 1121 and the longitudinal partition plate 1122 are partition plates with different extension directions during assembly, and the lengths of the two can be the same or different. The heights of the two can be the same or different. The transverse partition plate 1121 includes a first transverse panel 1121a and a second transverse panel 1121b formed by bending, and a first slot is formed on each of the first transverse panel 1121a and the second transverse panel 1121b. The slot of each first slot is located at the bending portion at the top end of the first transverse panel 1121a and the second transverse panel 1121b and is communicated. Unlike the conventional flat plate structure, the transverse partition plate 1121 in this embodiment is folded. It can be understood that the transverse partition plate 1121 is a one-piece structure, that is, the one-piece plate is folded from the middle to the two ends opposite to each other, and the portions on both sides of the bending portion are the first transverse panel 1121a and the second transverse panel 1121b, respectively. Specifically, the length, width and height of the first transverse panel 1121a and the second transverse panel 1121b are equal. It should be noted that one end of the longitudinal partition plate 1122 in the folded state is a bending portion, and the opposite end is an opening end, that is, an end opened by the first longitudinal panel 1122a and the second longitudinal panel 1122b under the action of their own tension. The slot of the first slot is located at the bending portion and extends downward along the height direction. Exemplarily, the depth of the first slot is half of the height of the first transverse panel 1121a or the second transverse panel 1121b.

[0049] The longitudinal partition plate 1122 comprises a first longitudinal panel 1122a and a second longitudinal panel 1122b formed by bending, and the first longitudinal panel 1122a and the second longitudinal panel 1122b are respectively provided with a second slot, and the slot opening of each second slot is located at the opening end of the first longitudinal panel 1122a and the second longitudinal panel 1122b. Unlike the conventional flat plate structure, the longitudinal partition plate 1122 in this embodiment is also folded. It can be understood that the longitudinal partition plate 1122 is a one-piece structure, that is, the one-piece plate is folded in the middle to the opposite ends, and the parts located on both sides of the bending part are the first longitudinal panel 1122a and the second longitudinal panel 1122b. Specifically, the length, width and height of the first longitudinal panel 1122a and the second longitudinal panel 1122b are equal. It should be noted that the one end of the folded longitudinal partition plate 1122 is the bending part, and the opposite end is the opening end, that is, the end of the first longitudinal panel 1122a and the second longitudinal panel 1122b opened under the action of its own tension. The slot opening of the second slot is located at the opening end and extends upward along the height direction. For example, the depth of the second slot is half the height of the first longitudinal panel 1122a or the second longitudinal panel 1122b. The transverse partition plate 1121 and the longitudinal partition plate 1122 are obviously distinguished at the slot opening part, the transverse partition plate 1121 is at the bending part, and specifically the slot opening is at the center ridge line position, and the longitudinal partition plate 1122 is at the bending opening position.

[0050] The transverse partition plate 1121 and the longitudinal partition plate 1122 are inserted through the first slot and the second slot to divide the inside of the outer box 111 into a plurality of ammunition accommodating cavities 1123 distributed in a grid shape. That is, the opening end of the transverse partition plate 1121 is inserted into the second slot, and the bending end of the longitudinal partition plate 1122 is inserted into the first slot, so that the transverse partition plate 1121 and the longitudinal partition plate 1122 are stably connected. For example, the transverse partition plate 1121 and the longitudinal partition plate 1122 are perpendicularly inserted at 90 degrees. After the ammunition 3 is loaded into the ammunition accommodating cavities 1123 formed by the transverse partition plate 1121 and the longitudinal partition plate 1122, the ammunition 3 is naturally separated into independent ammunition 3 that meets the specific safe firing and firing isolation distance, and the main body part of the ammunition 3 is protected by the interleaved wall surface.

[0051] The inner holder 112 is formed by inserting the transverse partition plate 1121 and the longitudinal partition plate 1122, and the transverse partition plate 1121 and the longitudinal partition plate 1122 divide the inside of the outer box 111 into a plurality of ammunition accommodating cavities 1123 distributed in a grid shape. The ammunition 3 can be loaded vertically side by side into the ammunition accommodating cavities 1123, and under the limitation of the outer box 111 body and the transverse partition plate 1121 and the longitudinal partition plate 1122, the ammunition 3 can be effectively limited and stably supported, and the inner holder 112 isolates each ammunition 3, avoiding mutual collision between the ammunition 3 and damage caused thereby.

[0052] In addition, the transverse partition plate 1121 and the longitudinal partition plate 1122 are not conventional thick flat plates, but are bent plates. The transverse partition plate 1121 comprises a first transverse face plate 1121a and a second transverse face plate 1121b which are bent, and the longitudinal partition plate 1122 comprises a first longitudinal face plate 1122a and a second longitudinal face plate 1122b which are bent. The rebound caused by the tension of the plate during the bending process combines the limiting of the boundaries of the first slot and the second notch, and can form a stable support surface. In addition, the transverse partition plate 1121 and the longitudinal partition plate 1122 can be made of a plate with a relatively small thickness. For the same gap size between adjacent ammunitions 3, the inner holder 112 of the ammunition packaging box 11 provided by the present application has a greatly reduced plate thickness compared with the straight plate in the prior art. On the one hand, the material cost is reduced, and on the other hand, the processing difficulty is significantly reduced by the way of folding after slotting by a die cutting knife, and the preparation is more convenient. Therefore, the overall preparation cost is significantly reduced.

[0053] In some embodiments, the length of the transverse partition plate 1121 is greater than the length of the longitudinal partition plate 1122, the length of the transverse partition plate 1121 is equal to the inner length of the outer box 111, and the length of the longitudinal partition plate 1122 is equal to the inner width of the outer box 111. That is, the transverse partition plate 1121 is a short partition plate, the longitudinal partition plate 1122 is a long partition plate, and the outer box 111 is a cuboid box. The two ends of the transverse partition plate 1121 and the two ends of the longitudinal partition plate 1122 can be respectively abutted with the inner wall of the outer box 111, so that the inner holder 112 is more stable and reliable. The transverse partition plate 1121 and the longitudinal partition plate 1122 are specifically vertically inserted with each other to form a grid-shaped inner holder 112.

[0054] In some embodiments, the outer box 111 is provided with a plurality of transverse partitions 1121 and a plurality of longitudinal partitions 1122, each of the transverse partitions 1121 and the longitudinal partitions 1122 is distributed transversely and is inserted into the corresponding first slot and the second slot to form a square cross-section ammunition accommodating cavity 1123. For example, the transverse partitions 1121 are provided with a plurality of first slots and are respectively inserted into the corresponding longitudinal partitions 1122; the longitudinal partitions 1122 are also provided with a plurality of second slots and are respectively inserted into the corresponding transverse partitions 1121, each of the transverse partitions 1121 and the longitudinal partitions 1122 is limited to form a stable inner holder 112 structure. And through the cooperation of the plurality of transverse partitions 1121 and the plurality of longitudinal partitions 1122, the ammunition accommodating cavities 1123 are distributed in a grid shape, the number of the ammunition accommodating cavities 1123 is large, so that the number of the ammunition 3 that can be accommodated is large, which is convenient for packaging. In addition, the shape of the ammunition 3 is usually cylindrical or conical, therefore, through the cooperation of the plurality of transverse partitions 1121 and the plurality of longitudinal partitions 1122, the square cross-section ammunition accommodating cavities 1123 are divided to make the four side walls of the ammunition accommodating cavities 1123 respectively contact and position the outer circumferential surface of the ammunition 3, so that the ammunition 3 is more stable and reliable when placed in the ammunition accommodating cavities 1123, and the shaking and collision of the ammunition 3 are avoided. For example, the width of each of the ammunition accommodating cavities 1123 corresponding to the same section is equal, that is, the size of each of the ammunition accommodating cavities 1123 is the same, so as to facilitate the assembly of the same specification ammunition 3.

[0055] In some embodiments, the distance between the two adjacent longitudinal partitions 1122 decreases from one end of the slot to the middle of the first slot; the distance between the two adjacent transverse partitions 1121 decreases from one end of the slot to the middle of the first slot. It can be understood that the middle of the ammunition accommodating cavity 1123 refers to the middle part except the two ends, and is not limited to the center of the two ends. As described above, the upper part of the grid space cross-section formed by the transverse partitions 1121 and the longitudinal partitions 1122 is in the shape of a trapezoid, specifically, the upper part of the ammunition accommodating cavity 1123 is in the shape of a hexahedron, which ensures the stable posture of the cylindrical or conical ammunition 3 when entering, that is, the posture of the ammunition 3 when entering the ammunition accommodating cavity 1123 from top to bottom is stable and smooth. Specifically, the ammunition 3 is inserted into the ammunition accommodating cavity 1123 in a state that the bottom edge of the ammunition 3 is vertically upward. According to the needs, the distance between the two adjacent longitudinal partitions 1122 can also decrease from one end of the slot to the middle of the first slot, or the distance between the two adjacent longitudinal partitions 1122 can decrease from one end of the slot to the middle of the first slot.

[0056] In some embodiments, the wall surface of the first slot abuts against the first longitudinal panel 1122a and the second longitudinal panel 1122b, so that the top end of the first longitudinal panel 1122a and the second longitudinal panel 1122b has a first preset opening angle, and the bottom end has a second preset opening angle. The first longitudinal panel 1122a and the second longitudinal panel 1122b are formed by folding the panel, for example, by folding paper, so that in the folding process, the first longitudinal panel 1122a and the second longitudinal panel 1122b naturally open from the folded end to the other end due to the springback of the panel itself in the tension state. The folded end is the top end, and the opening angle end is the bottom end. That is, the top end of the first longitudinal panel 1122a and the second longitudinal panel 1122b is connected, and the bottom end has a larger opening angle. In this embodiment, since the transverse partition plate 1121 and the longitudinal partition plate 1122 are inserted through the first slot and the second slot, the first slot can limit the first longitudinal panel 1122a and the second longitudinal panel 1122b to prevent the opening angle from being too large. The panel tension springback and the first slot boundary limiting are used to make the longitudinal partition plate 1122 meet the specific isolation thickness required by the original inner holder 112. Specifically, the first longitudinal panel 1122a and the second longitudinal panel 1122b respectively abut against the wall surface of the first slot, so that compared with the natural state, the opening angle of the top end of the first longitudinal panel 1122a and the second longitudinal panel 1122b is reduced to the first preset opening angle, and the bottom end of the first longitudinal panel 1122a and the second longitudinal panel 1122b is limited from the open state to the inward state and has the second preset opening angle. That is, the first longitudinal panel 1122a and the second longitudinal panel 1122b have a state of inwardly closing at both ends and slightly opening in the middle. The first longitudinal panel 1122a and the second longitudinal panel 1122b naturally fill the slot boundary by using their own tension, combined with the limiting of the first slot, to form a triangular stable support surface. On the one hand, it can effectively separate each ammunition 3 in a columnar or conical shape, and can better buffer and absorb the ammunition 3; on the other hand, the first preset opening angle makes the distance between the adjacent two longitudinal partition plates 1122 decrease from one end of the slot of the first slot to the middle, thereby facilitating the insertion of the ammunition 3; on the other hand, for the same gap size between adjacent ammunition 3, the thickness of the panel required by the transverse partition plate 1121 and the longitudinal partition plate 1122 is greatly reduced.

[0057] Exemplarily, the height of the transverse partition plate 1121 and the longitudinal partition plate 1122 is the same, the depth of the first slot is half of the height of the transverse partition plate 1121, the depth of the second slot is half of the height of the longitudinal partition plate 1122, the wall surface of the first slot is in abutment with the first longitudinal panel 1122a and the second longitudinal panel 1122b, so that the top end of the first longitudinal panel 1122a and the second longitudinal panel 1122b is in a first preset opening angle, and the bottom end is in a second preset opening angle, and the range of the first preset opening angle is 0.1-10 degrees, preferably 0.5-5 degrees, and the range of the second preset opening angle is 0.1-10 degrees, preferably 0.5-5 degrees, and the transverse partition plate 1121 and the longitudinal partition plate 1122 are both paper plates. As arranged above, the transverse partition plate 1121 and the longitudinal partition plate 1122 can rebound well, thereby providing good buffering and shock absorption effect, and the overall structure is stable and reliable.

[0058] In some embodiments, the wall surface of the second slot is in abutment with the first transverse panel 1121a and the second transverse panel 1121b, so that the top end of the first transverse panel 1121a and the second transverse panel 1121b is in a first preset opening angle, and the bottom end is in a second preset opening angle. Its effect is similar to the above-mentioned embodiments, which will not be described here.

[0059] In some embodiments, the first transverse panel 1121a and the second transverse panel 1121b have a first gap therebetween, and the maximum width of the first gap is 2-4 times the thickness of the first transverse panel 1121a. It can be understood that the size of the first gap corresponding to different positions between the first transverse panel 1121a and the second transverse panel 1121b can be different. For example, the top end of the first transverse panel 1121a and the second transverse panel 1121b has a first preset opening angle, and the bottom end has a second preset opening angle. The maximum gap between the first transverse panel 1121a and the second transverse panel 1121b is 2-4 times the thickness of the first transverse panel 1121a. For example, the maximum gap is 2.0 times, 2.2 times, 2.4 times, 2.6 times, 2.8 times, 3.0 times, 3.2 times, 3.4 times, 3.6 times, 3.8 times, or 4.0 times the thickness of the first transverse panel 1121a. The first gap between the first transverse panel 1121a and the second transverse panel 1121b is in the above range, which can effectively separate the cylindrical or conical ammunition 3, and can better buffer and absorb the ammunition 3. At the same time, for the same gap size between adjacent ammunition 3, the thickness of the transverse partition plate 1121 required is greatly reduced. For example, the gap size between adjacent ammunition 3 is 2 mm, and the thickness of the transverse partition plate 1121 required is 2 mm. In this embodiment, the first transverse panel 1121a and the second transverse panel 1121b have a 1.0 mm gap, and only a 0.5 mm thick plate is needed to form the transverse partition plate 1121 by folding. In this embodiment, the transverse partition plate 1121 and the longitudinal partition plate 1122 are cut and grooved by a 1 / 4 thickness of the original specific thickness of the paperboard, and then folded, which is simple in processing technology and significantly reduces the cost of paperboard.

[0060] In some embodiments, the first longitudinal panel 1122a and the second longitudinal panel 1122b have a second gap therebetween, and the maximum width of the second gap is 2-4 times the thickness of the first longitudinal panel 1122a. It can be understood that the size of the first gap corresponding to different positions between the first longitudinal panel 1122a and the second longitudinal panel 1122b can be different. For example, the top end of the first longitudinal panel 1122a and the second longitudinal panel 1122b has a first preset opening angle, and the bottom end has a second preset opening angle. The maximum gap between the first longitudinal panel 1122a and the second longitudinal panel 1122b is 2-4 times the thickness of the first longitudinal panel 1122a. For example, the maximum gap is 2.0 times, 2.2 times, 2.4 times, 2.6 times, 2.8 times, 3.0 times, 3.2 times, 3.4 times, 3.6 times, 3.8 times, or 4.0 times the thickness of the first longitudinal panel 1122a. The first gap between the first longitudinal panel 1122a and the second longitudinal panel 1122b is in the above range, which can effectively separate the cylindrical or conical ammunition 3 and better buffer the ammunition 3. At the same time, for the same gap size between adjacent ammunition 3, the thickness of the longitudinal partition plate 1122 required by the plate is greatly reduced. For example, the gap size between adjacent ammunition 3 is 2 mm, and the thickness of the longitudinal partition plate 1122 required is 2 mm. In this embodiment, the first longitudinal panel 1122a and the second longitudinal panel 1122b have a gap of 1.0 mm, and only a plate with a thickness of 0.5 mm is needed to form the longitudinal partition plate 1122 by folding.

[0061] In some embodiments, the outer box 111 includes a box body 1111 and a box cover 1112 arranged on the box body 1111. The top end of the box body 1111 has an opening, and the box cover 1112 is used to open or close the opening. The inner holder 112 is arranged in the box body 1111, and the first slot is located at one end of the second slot facing the opening. The outer box 111 adopts the design of the box body 1111 and the box cover 1112, which facilitates the placement of the inner holder 112 in the outer box 111 and the placement of the ammunition 3 in the outer box 111, and is convenient for packaging. For example, the box cover 1112 is connected to the opening end of the box body 1111 and can be folded relative to the box body 1111 to open or close the opening. When the opening is closed, the inside is completely closed to the ammunition 3, the transverse partition plate 1121, and the longitudinal partition plate 1122. The outer box 111 can be a paper box, which can be cut and shaped from a paperboard and then folded into the outer box 111.

[0062] In some embodiments, the opening end of the transverse partition 1121 is parallel to and abuts the inner bottom surface of the outer box 111. After the transverse partition 1121 and the longitudinal partition 1122 are inserted, the transverse partition 1121 is placed at the lower end as a support for the longitudinal partition 1122, and the longitudinal partition 1122 is placed at the upper end as a supported part, i.e., the longitudinal partition 1122 presses the transverse partition 1121. That is, the bending portions of the transverse partition 1121 and the longitudinal partition 1122 are both directed to the opening of the box body 1111, the first transverse panel 1121a and the second transverse panel 1121b of the bending portion are connected, and the first longitudinal panel 1122a and the second longitudinal panel 1122b are connected, so that the structure is regular and the ammunition 3 can be easily inserted into the ammunition accommodating cavity 1123 from one end of the bending portion.
