Description

Technical Field

[0001] The present invention relates to the technical field of ammunition packaging, and more particularly to an ammunition packaging box. Background Art

[0002] After the ammunition is produced and processed, it generally needs to be packaged before transportation. For cylindrical or conical ammunition, because the bottom end of the main body of the ammunition shell has a raised bottom edge, there will be a fixed gap between each ammunition and the main body of each ammunition when it is packed. Therefore, when packaging, the ammunition needs to be fixed with a paper box shell and an inner bracket. Usually, a solid paper partition of a specific thickness is used as a bracket to separate and fix it to prevent the ammunition from colliding with each other during transportation and causing damage. Severe collisions may even cause the ammunition to burn and explode.

[0003] The paper partition used as the inner bracket is a key component to form the internal isolation space of the packaging body. The paper partition needs to be slotted with a specific length and inserted into each other to form a grid for inserting cylindrical or conical ammunition. Since the paper partition is thick (usually 2mm), the cost is high, and the cardboard is hard, it can only be slotted with a milling cutter, but the milled slots have many burrs and flash, and the quality of the inner bracket of the paper partition is poor, resulting in poor processing technology and high processing costs. Therefore, the thickness of the paper partition limits the processing quality and production cost of the inner bracket.

[0004] In summary, how to effectively solve the problems of poor processing quality and high cost of the inner bracket of the ammunition packaging box is a problem that technical personnel in this field need to solve. Summary of the invention

DETAILED DESCRIPTION

[0036] The embodiment of the invention discloses an ammunition packaging box, which is used to improve the processing technology and support hardness of an inner bracket and significantly reduce the cost.

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] The ammunition packaging box provided by the present invention can be used to realize the packaging of ammunition. It includes an outer box and an inner bracket. The outer box is an outer packaging, which is usually in the shape of a cuboid or a cube. The inner bracket is placed in the outer box, and the outer box is divided into small spaces to accommodate ammunition. The materials of the outer box and the inner bracket include but are not limited to cardboard. Exemplarily, the outer box is a carton, such as a corrugated cardboard box, and the inner bracket is made of cardboard, such as corrugated cardboard. The ammunition packaging box is made of paper, which is lighter and more environmentally friendly. In the present application, the structure of the inner bracket is improved, and the folded transverse partition and longitudinal partition are used to replace the conventional thick cardboard, which is mainly described in the following embodiments.

[0039] In some embodiments, see Figure 1-Figure 2 The ammunition packaging box provided by the present invention includes an outer box 1 and an inner bracket 2. The inner bracket 2 is arranged in the outer box 1, and the inner bracket 2 includes a transverse partition 21 and a longitudinal partition 22. It is understandable that the transverse partition 21 and the longitudinal partition 22 are partitions extending in different directions when assembled, and the lengths of the two can be the same or different. The heights of the two can be the same or different. Among them, the transverse partition 21 includes a first transverse panel 211 and a second transverse panel 212 formed by bending, and the first transverse panel 211 and the second transverse panel 212 are respectively provided with a first slot 23, and the notches of each first slot 23 are located at the bending of the top of the first transverse panel 211 and the second transverse panel 212 and are connected. Different from the conventional flat plate structure, the transverse partition 21 in this embodiment is folded. It is understandable that the transverse partition 21 is an integrated structure, that is, the integrated plate is folded from the middle to the two ends facing each other, and the parts located on both sides of the bending are the first transverse panel 211 and the second transverse panel 212 respectively. Specifically, the length, width and height of the first transverse panel 211 and the second transverse panel 212 are equal. It should be noted that one end of the longitudinal partition 22 in the folded state is a bend, and the other end is an angle end, that is, the end of the first longitudinal panel 221 and the second longitudinal panel 222 that is opened under the action of its own tension. The notch of the first slot 23 is located at the bend and extends downward in the height direction. For example, the depth of the first slot 23 is half the height of the first transverse panel 211 or the second transverse panel 212.

[0040] The longitudinal partition 22 includes a first longitudinal panel 221 and a second longitudinal panel 222 formed by bending, and the first longitudinal panel 221 and the second longitudinal panel 222 are respectively provided with a second slot 24, and the notches of each second slot 24 are respectively located at the angled ends of the first longitudinal panel 221 and the second longitudinal panel 222. Different from the conventional flat plate structure, the longitudinal partition 22 in this embodiment is also folded. It can be understood that the longitudinal partition 22 is an integrated structure, that is, the integrated plate is folded from the middle to the two ends opposite, and the parts located on both sides of the bend are the first longitudinal panel 221 and the second longitudinal panel 222. Specifically, the length, width and height of the first longitudinal panel 221 and the second longitudinal panel 222 are equal. It should be noted that one end of the longitudinal partition 22 in the folded state is the bend, and the other end opposite is the angled end, that is, the end of the first longitudinal panel 221 and the second longitudinal panel 222 opened under the action of their own tension. The slot of the second slot 24 is located at the angle end and extends upward in the height direction. For example, the depth of the second slot 24 is half the height of the first longitudinal panel 221 or the second longitudinal panel 222. The transverse partition 21 and the longitudinal partition 22 are clearly distinguished in the slot opening position. The transverse partition 21 is slotted at the bend, specifically at the center ridge position, and the longitudinal partition 22 is slotted at the bend angle position.

[0041] The transverse partition 21 and the longitudinal partition 22 are inserted into each other through the first slot 23 and the second slot 24, so as to divide the interior of the outer box 1 into a plurality of ammunition accommodating chambers 25 distributed in a grid shape. That is, the angled end of the transverse partition 21 is inserted into the second slot 24, and the bent end of the longitudinal partition 22 is inserted into the first slot 23, so as to stably connect the transverse partition 21 and the longitudinal partition 22. Exemplarily, the transverse partition 21 and the longitudinal partition 22 are inserted vertically at 90 degrees. After the ammunition 3 is loaded into the ammunition accommodating chamber 25 formed by the staggered transverse partition 21 and the longitudinal partition 22, it is naturally divided into independent ammunition 3 that meets the specific safety shot-to-shot isolation distance, and the main body of the ammunition 3 is protected by the staggered wall surface.

[0042] In the ammunition packaging box provided by the present invention, the inner bracket 2 is formed by inserting the transverse partition 21 and the longitudinal partition 22, and the transverse partition 21 and the longitudinal partition 22 divide the interior of the outer box 1 into a plurality of ammunition accommodating chambers 25 distributed in a grid shape. The ammunition 3 can be vertically loaded into the ammunition accommodating chambers 25 side by side according to the shot. Under the limitation of the outer box 1 body and the transverse partition 21 and the longitudinal partition 22, the ammunition 3 can be effectively limited and firmly supported, and the inner bracket 2 isolates the ammunition 3 from each other, thereby avoiding collision between the ammunition 3 and the damage caused thereby.

[0043] In addition, the transverse partition 21 and the longitudinal partition 22 are different from conventional thick flat plates, but are bent plates. The transverse partition 21 includes a first transverse panel 211 and a second transverse panel 212 formed by bending, and the longitudinal partition 22 includes a first longitudinal panel 221 and a second longitudinal panel 222 formed by bending. The rebound formed by the tension of the plate during the bending process combined with the limiting of the first slot 23 and the second slot boundary can form a stable support surface. The transverse partition 21 and the longitudinal partition 22 can be made of thinner plates, that is, for the same gap size between adjacent ammunition 3, the inner bracket 2 of the ammunition packaging box provided by the present application has a greatly reduced thickness of the plate relative to the straight plate in the prior art, which reduces the material cost on the one hand, and can be processed by folding in half after slotting with a die cutter, which significantly reduces the difficulty of the processing technology and makes the preparation more simple, so the overall preparation cost is significantly reduced.

[0044] In some embodiments, the length of the transverse partition 21 is greater than the length of the longitudinal partition 22, the length of the transverse partition 21 is equal to the inner length of the outer box 1, and the length of the longitudinal partition 22 is equal to the inner width of the outer box 1. That is, the transverse partition 21 is a short partition, the longitudinal partition 22 is a long partition, and the outer box 1 is a corresponding rectangular box. The two ends of the transverse partition 21 and the two ends of the longitudinal partition 22 can respectively abut against the inner wall of the outer box 1, so that the inner bracket 2 is more stable and reliable. The transverse partition 21 and the longitudinal partition 22 are specifically inserted vertically into each other to form a grid-shaped inner bracket 2.

[0045] In some embodiments, the outer box 1 is provided with a plurality of transverse partitions 21 and a plurality of longitudinal partitions 22, and each transverse partition 21 and longitudinal partition 22 is crisscrossed and inserted through the corresponding first slots 23 and second slots 24 to form an ammunition accommodating chamber 25 with a square cross section. Exemplarily, the transverse partition 21 is provided with a plurality of first slots 23, which are respectively inserted into the corresponding longitudinal partitions 22; the longitudinal partition 22 is also provided with a plurality of second slots 24, which are respectively inserted into the corresponding transverse partitions 21, and each transverse partition 21 and each longitudinal partition 22 are mutually limited to form a stable inner bracket 2 structure. And through the cooperation of the plurality of transverse partitions 21 and the plurality of longitudinal partitions 22, the ammunition accommodating chambers 25 formed are distributed in a grid shape, and the number of ammunition accommodating chambers 25 is large, so the number of 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, so the ammunition accommodating chamber 25 with a square cross section is divided by the cooperation of multiple transverse partitions 21 and multiple longitudinal partitions 22, so that the four side walls of the ammunition accommodating chamber 25 can be respectively contacted and positioned with the outer peripheral surface of the ammunition 3, so that the ammunition 3 is placed therein more stably and reliably, and the shaking and collision of the ammunition 3 are avoided. Exemplarily, the widths of the ammunition accommodating chambers 25 corresponding to the same cross section are equal, that is, the sizes of the ammunition accommodating chambers 25 are the same, so as to facilitate the assembly of ammunition 3 of the same specification.

[0046] In some embodiments, see Figure 3, the spacing between two adjacent longitudinal partitions 22 decreases from one end of the notch of the first slot 23 to the middle; the spacing between two adjacent transverse partitions 21 decreases from one end of the notch of the first slot 23 to the middle. It can be understood that the middle of the ammunition accommodating chamber 25 refers to its middle part except for the two ends, and is not limited to the center of the two ends. As set above, the upper part of the cross section of the grid space formed by the transverse partition 21 and the longitudinal partition 22 is a trapezoidal shape with a larger upper part and a smaller lower part. Specifically, the upper part of the ammunition accommodating chamber 25 is a hexahedral space with a larger upper part and a smaller lower part, which ensures that the posture of the cylindrical or conical ammunition 3 is stable when it is lowered, that is, the posture of the ammunition 3 is stable and the introduction is smooth when it is loaded into the ammunition accommodating chamber 25 from top to bottom. Specifically, when placing, the ammunition 3 is inserted into the ammunition accommodating chamber 25 from one end of the notch of the first slot 23 with the bottom edge vertically facing upward. As required, the distance between two adjacent longitudinal partitions 22 may be set to decrease from one end of the notch of the first slot 23 to the middle, or the distance between two adjacent longitudinal partitions 22 may be set to decrease from one end of the notch of the first slot 23 to the middle.

[0047] In some embodiments, see Figure 4, the wall surface of the first slot 23 abuts against the first longitudinal panel 221 and the second longitudinal panel 222, so that the top of the first longitudinal panel 221 and the second longitudinal panel 222 is at a first preset angle α, and the bottom is at a second preset angle β. The first longitudinal panel 221 and the second longitudinal panel 222 are formed by folding a plate, and are formed by folding a cardboard, so during the bending process of the first longitudinal panel 221 and the second longitudinal panel 222, due to the rebound formed by the tension of the plate itself, it opens from one end of the bend to the other end in a natural state, and the bending end is the top end, and the angle end is the bottom end, that is, the top ends of the first longitudinal panel 221 and the second longitudinal panel 222 are connected, and the bottom ends are opened at a larger angle. In this embodiment, since the transverse partition 21 and the longitudinal partition 22 are inserted into each other through the first slot 23 and the second slot 24, the first slot 23 can limit the first longitudinal panel 221 and the second longitudinal panel 222 to prevent the angle from being too large. The tension rebound of the plate and the boundary limit of the first slot 23 are used to make the longitudinal partition 22 meet the specific isolation thickness that the original inner bracket 2 needs to reserve. Specifically, the first longitudinal panel 221 and the second longitudinal panel 222 are respectively against the wall surface of the first slot 23, so compared with the natural state, the opening angle of the top of the first longitudinal panel 221 and the second longitudinal panel 222 is reduced to the first preset opening angle α, and the bottom of the first longitudinal panel 221 and the second longitudinal panel 222 is limited from the open state to the retracted state and presents the second preset opening angle β, that is, the first longitudinal panel 221 and the second longitudinal panel 222 are inwardly retracted at both ends and slightly opened in the middle. The self-tension of the first longitudinal panel 221 and the second longitudinal panel 222, combined with the limitation of the first slot 23, can naturally fill the notch boundary to form a triangular stable support surface. On the one hand, it can effectively separate the cylindrical or conical ammunition 3 and can play a better role in buffering and shock absorbing the ammunition 3; on the other hand, the first preset opening angle α makes the distance between the two adjacent longitudinal partitions 22 decrease from one end of the notch of the first slot 23 to the middle, so as to facilitate the insertion of the ammunition 3; on the other hand, for the same gap size between adjacent ammunition 3, the thickness of the plate required for the transverse partition 21 and the longitudinal partition 22 is greatly reduced.

[0048] Exemplarily, the height of the transverse partition 21 and the longitudinal partition 22 is the same, and the depth of the first slot 23 is half of the height of the transverse partition 21, and the depth of the second slot 24 is half of the height of the longitudinal partition 22. The wall of the first slot 23 abuts against the first longitudinal panel 221 and the second longitudinal panel 222, so that the top of the first longitudinal panel 221 and the second longitudinal panel 222 presents a first preset angle α, and the bottom presents a second preset angle β, and the first preset angle α ranges from 0.1 to 10 degrees, preferably 0.5 to 5 degrees, and the second preset angle β ranges from 0.1 to 10 degrees, preferably 0.5 to 5 degrees, and the transverse partition 21 and the longitudinal partition 22 are both cardboard. As set above, the transverse partition 21 and the longitudinal partition 22 can rebound well, thereby providing a good buffering and shock absorbing effect, and the overall structure is stable and reliable.

[0049] In some embodiments, the wall surface of the second slot 24 abuts against the first horizontal panel 211 and the second horizontal panel 212, so that the top ends of the first horizontal panel 211 and the second horizontal panel 212 are at a first preset angle α, and the bottom ends are at a second preset angle β. Its function is similar to that of the above embodiment, and will not be repeated here.

[0050] In some embodiments, there is a first gap 26 between the first horizontal panel 211 and the second horizontal panel 212, and the maximum width of the first gap 26 is 2 to 4 times the thickness of the first horizontal panel 211. It is understandable that the sizes of the first gap 26 corresponding to different positions between the first horizontal panel 211 and the second horizontal panel 212 may be different. For example, if the top ends of the first horizontal panel 211 and the second horizontal panel 212 are at a first preset angle α, and the bottom ends are at a second preset angle β, then the maximum gap between the first horizontal panel 211 and the second horizontal panel 212 is 2 to 4 times the thickness of the first horizontal panel 211, and illustratively, it 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, and 4.0 times the thickness of the first horizontal panel 211. There is a first gap 26 between the first horizontal panel 211 and the second horizontal panel 212, and the first gap 26 is within the above range, which can effectively separate the cylindrical or conical ammunition 3 and play a more effective role in buffering and shock absorbing the ammunition 3; at the same time, for the same gap size between adjacent ammunition 3, the thickness of the plate required for the transverse partition 21 is greatly reduced. For example, if the gap size between adjacent ammunition 3 is 2mm, the thickness of the transverse partition 21 needs to be 2mm. In this embodiment, there is a 1.0mm gap between the first horizontal panel 211 and the second horizontal panel 212, and only a plate with a thickness of 0.5mm is needed to form the transverse partition 21 by folding, that is, the transverse partition 21 and the longitudinal partition 22 are made of 1 / 4 thickness cardboard of the original specific thickness cardboard, and then folded in half after die cutting. The processing technology is simple and the cardboard cost is significantly reduced.

[0051] In some embodiments, there is a second gap 27 between the first longitudinal panel 221 and the second longitudinal panel 222, and the maximum width of the second gap 27 is 2 to 4 times the thickness of the first longitudinal panel 221. It is understandable that the sizes of the first gap 26 corresponding to different positions between the first longitudinal panel 221 and the second longitudinal panel 222 may be different. For example, if the top ends of the first longitudinal panel 221 and the second longitudinal panel 222 are at a first preset angle α, and the bottom ends are at a second preset angle β, then the maximum gap between the first longitudinal panel 221 and the second longitudinal panel 222 is 2 to 4 times the thickness of the first longitudinal panel 221, and illustratively, it 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, and 4.0 times the thickness of the first longitudinal panel 221. There is a first gap 26 between the first longitudinal panel 221 and the second longitudinal panel 222, and the first gap 26 is within the above range, which can effectively separate the cylindrical or conical ammunition 3 and play a more effective role in buffering and shock absorbing the ammunition 3; at the same time, for the same gap size between adjacent ammunition 3, the thickness of the plate required for the longitudinal partition 22 is greatly reduced. For example, if the gap size between adjacent ammunition 3 is 2mm, the thickness of the longitudinal partition 22 needs to be 2mm. In this embodiment, there is a 1.0mm gap between the first longitudinal panel 221 and the second longitudinal panel 222, and only a plate with a thickness of 0.5mm is needed to form the longitudinal partition 22 by folding.

[0052] In some embodiments, the outer box 1 includes a box body 11 and a box cover 12 disposed on the box body 11, the top of the box body 11 has an opening 111, the box cover 12 is used to open or close the opening 111, the inner bracket 2 is disposed in the box body 11, and the first slot 23 is located at one end of the second slot 24 facing the opening 111. The outer box 1 adopts the design of the box body 11 and the box cover 12, which is convenient for placing the inner bracket 2 in the outer box 1, and also convenient for placing the ammunition 3 in the outer box 1, and is convenient for packaging. Exemplarily, the box cover 12 is connected to the opening 111 end of the shell box body 11, and can be folded relative to the box body 11 to open or close the opening 111. When the opening 111 is closed, the ammunition 3, the transverse partition 21 and the longitudinal partition 22 are completely enclosed inside. The outer box 1 can be specifically a paper box, which can be cut and formed by cardboard and then folded into the outer box 1.

[0053] In some embodiments, the angled end of the transverse partition 21 is parallel to and abuts against the inner bottom surface of the outer box 1. After the transverse partition 21 and the longitudinal partition 22 are inserted, the transverse partition 21 is used as a base to support the longitudinal partition 22 placed at the lower end, and the longitudinal partition 22 is placed at the upper end as a supported member, that is, the longitudinal partition 22 presses the transverse partition 21. That is, the bending parts of the transverse partition 21 and the longitudinal partition 22 are both facing the opening 111 of the box body 11, the first transverse panel 211 and the second transverse panel 212 are connected at the bending part, and the first longitudinal panel 221 and the second longitudinal panel 222 are connected, so the structure is regular, which facilitates the insertion of the ammunition 3 from one end of the bending part into the ammunition accommodating cavity 25.

[0054] In some embodiments, the central ridge line of the bend of the longitudinal partition 22 is parallel to the top surface of the outer box 1 and is arranged at intervals. The depth of the box body 11 is specifically the same as the height of the ammunition 3, so that the bottom surface of the box body 11 and the top surface after the opening 111 is closed can respectively abut against the two ends of the ammunition 3 to limit the position and prevent the ammunition 3 from shaking. After the ammunition 3 is loaded into the ammunition accommodating cavity 25 formed by the staggered transverse partition 21 and the longitudinal partition 22, the bottom edge of the ammunition 3 is separated. The height of the longitudinal partition 22 is less than the depth of the box body 11, that is, the longitudinal partition 22 can separate the ammunition 3 on the one hand to prevent them from colliding, and at the same time, the bottom edge of the ammunition 3 can be exposed, which is convenient for observing the insertion status of the ammunition 3.

[0055] In some embodiments, the first transverse panel 211 and the second transverse panel 212 are used to be tangent to the outer peripheral surface of the main body of the ammunition 3; the first longitudinal panel 221 and the second longitudinal panel 222 are used to be tangent to the outer peripheral surface. Exemplarily, the loading direction of the cylindrical or conical ammunition 3 is that the height direction of the ammunition 3 is perpendicular to the interlaced grid space surface of the transverse partition 21 and the longitudinal partition 22, and the arc cylindrical surface of the cylindrical or conical ammunition 3 is tangent to the transverse partition 21 and the longitudinal partition 22. That is, the transverse partition 21 and the longitudinal partition 22 are tangent to the outer peripheral surface of the main body of the ammunition 3, on the one hand, they can play a supporting and limiting role for the ammunition 3 to prevent it from shaking, and at the same time play a buffering and shock absorbing role to prevent the ammunition 3 from overturning and being damaged during transportation. On the other hand, the contact surface generated by the tangency is small, even if the ammunition 3 shakes relative to the transverse partition 21 or the longitudinal partition 22, the friction generated by the two is small, so the corresponding friction wear or friction heat is small, avoiding the adverse effects of friction on the ammunition 3.
