Description

Technical Field

[0001] The present invention relates to the technical field of logistics packaging, and in particular to an integrated packaging box capable of automatically filling gas and a manufacturing method thereof. Background Art

[0002] The common packaging methods for preventing damage to items during express delivery are: wrapping multiple layers of bubble pads or foam on the surface of the items, or filling the gaps in the packaging box with cushioning materials. They are not designed for a certain type of items. They are only placed in the corresponding gaps after the items are placed. The size of the cushioning materials is not compatible with the size of the box, so it is difficult to have a better fit with the items, such as some fresh and food items. The invention patent with application publication number CN110893926A discloses a packaging method for special-shaped products, which mainly includes the following steps: according to the outer dimensions of the product to be packaged, determine the size of the carton set on the periphery of the product to be packaged, open the carton and lay a plastic bag film on the bottom of the carton; place the polyurethane foam material on the plastic bag film, and wrap the polyurethane foam material with the plastic bag film on all sides; place the product to be packaged on the plastic bag film at the bottom of the carton, and the polyurethane foam material can be foamed and formed according to the bottom structure of the product to be packaged to form bottom foam; similar to the above process, top foam can be formed. Using polyurethane foam material can indeed play a cushioning role for items, but this method is cumbersome to operate and inefficient: the plastic bag film needs to be cut to the appropriate size, and the amount of polyurethane foam material used each time also depends on experience. After spraying the polyurethane foam material on the plastic bag film, it is necessary to quickly fold the four sides to wrap the polyurethane foam material. Although this method improves the fit with the product, the hygiene cannot be guaranteed, so it is not suitable for fresh food and food items. Summary of the invention

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0030] The packaging box involved in the present invention comprises a box body 11 and swing covers 12 on the top thereof located at four sides. The box body 11 itself is a prior art, and a common packaging box is made of corrugated paper.

[0031] like Figure 1-Figure 5 As shown, a method for manufacturing an integrated packaging box that is automatically filled with gas includes the following steps:

[0032] S1. Turn on the first switch 51. The first gas generator 21 can quickly fill the gas into the first plastic bag film 31. The first plastic bag film 31 can be quickly spread out at the bottom of the box body 11 due to the influence of the gas pressure.

[0033] The gas generator can generate gas by chemical reaction, for example, hydrogen peroxide and manganese dioxide can generate oxygen, potassium permanganate and hydrogen peroxide can generate carbon dioxide, and sodium bicarbonate and hydrochloric acid can generate carbon dioxide. The gas generator can also use existing carbon dioxide small steel cylinders, such as the products of Zhongshan Jinshunyi Hardware Manufacturing Co., Ltd. The carbon dioxide small steel cylinder is filled with liquid carbon dioxide and can be made into different specifications, from a few grams to dozens of grams. In this embodiment, only the amount required to fill the plastic bag film is small, and generally 2 grams can fill most conventional-sized cartons.

[0034] S2, placing the items to be packaged on the first plastic bag film 31, partially deforming the first plastic bag film 31 to wrap the bottom of the items. The first plastic bag film 31 is made of food-grade PE film, and the items to be packaged can be fresh food, but it is not limited to this.

[0035] S3. Turn on the second switch 52, and the second gas generator 22 can quickly fill the gas into the second plastic bag film 32. The second plastic bag film 32 is spread on the top of the box body 11 and is above the article.

[0036] S4, closing the flap 12 of the packaging box. During the closing process, a partial area of ​​the second plastic bag film 32 is deformed by applying pressure to wrap the upper part of the article.

[0037] The plastic bag film is made into a closed structure, leaving an air inlet hole, which is connected to the gas generator through the corresponding material pipe. When the first plastic film is not unfolded, its width is slightly smaller than the width of the carton. After unfolding, it is basically consistent with the length and width of the carton and is in a filled state. In steps S1 and S3, the operator manually rotates the corresponding switch to open the corresponding gas generator's nozzle.

[0038] The above is the core concept of the present invention. The packaging box structure for implementing the above method is not unique. The following example illustrates a feasible packaging box structure that can quickly prepare a cushion and wrap the upper and lower sides of the items to be packaged to achieve the effect of compressive resistance and shock absorption.

[0039] Embodiment 1:

[0040] like Figure 1-Figure 5 As shown, an integrated packaging box for automatic gas filling includes a rectangular box body 11 and swing covers 12 on the top and four sides. The box body 11 itself is a prior art, and common packaging boxes are made of corrugated paper. For ease of description, the side walls of the box body are defined as a left box board 13, a bottom box board 15, and a rear box board 14.

[0041] The first gas generator 21, the first plastic bag film 31, the second gas generator 22, and the second plastic bag film 32 are arranged on the inner side of the left box board 13 of the box body 11. The first gas generator 21 is located above the first plastic bag film 31, and the second gas generator 22 is located below the second plastic bag film 32. In later use, the first plastic bag film 31 corresponds to the bottom of the item to be packaged; the second plastic bag film 32 corresponds to the upper part of the item to be packaged, so the first plastic bag film 31 and the second plastic bag film 32 are arranged at intervals from top to bottom.

[0042] In this embodiment, the first gas generator 21, the first plastic bag film 31, the second gas generator 22, and the second plastic bag film 32 are all arranged on the side wall of the same side, and the side wall is defined as the left box board 13. In other embodiments, the first gas generator 21 and the first plastic bag film 31 can also be arranged on the left box board 13 of the box body 11, and the second gas generator 22 and the second plastic bag film 32 can be arranged on the right box board of the box body 11.

[0043] The first gas generator 21 and the second gas generator 22 are both small carbon dioxide cylinders, the end surface of the jet end of the small carbon dioxide cylinder is provided with a pierceable surface, and the jet end is provided with an external thread section. The small carbon dioxide cylinder is an existing structural form.

[0044] The jet end of the first gas generator 21 is provided with a first switch 51, and the first plastic bag film 31 is connected to the first air pipe 41. After the first switch 51 is turned on, the first plastic bag film 31 is connected to the jet end through the first air pipe 41, that is, the small carbon dioxide cylinder can release gas into the first plastic bag film 31. The jet end of the second gas generator 22 is provided with a second switch 52, and the second plastic bag film 32 is connected to the second air pipe 42. After the second switch 52 is turned on, the second plastic bag film 32 is connected to the jet end through the second air pipe 42, that is, another small carbon dioxide cylinder can release gas into the first plastic bag film 31.

[0045] The first switch 51 and the second switch 52 are rotating parts, both of which include a rotating part 513, a first connecting part 511, and a second connecting part 512. The first connecting part 511 is connected to the second connecting part 512 and is integrally formed with the rotating part 513. The first connecting part 511 is threadedly connected to the corresponding jet end, that is, connected to the external thread section of the jet end. When installed, a part is pre-connected, that is, not screwed to the bottom. The first connecting part 511 is provided with an internal thread section 5111 for connecting to the external thread section. The first connecting part 511 is provided with a puncture needle 515 on the inner side of the internal thread section. When the rotating part 513 rotates, it can be used to puncture the puncturable surface of the end of the carbon dioxide small cylinder, thereby quickly releasing carbon dioxide gas. The puncture needle 515 adopts a conical tip structure. The fixed seat 514 where the puncture needle 515 is located is provided with a vent hole 5141, and carbon dioxide gas can enter the first air pipe 41 or the second air pipe 42 from the vent hole 5141. The fixed seat is integrally formed with the rotating part. One or two ventilation holes 5141 may be provided. In other embodiments, the needle may be directly designed as a hollow structure with ventilation holes provided on the surface.

[0046] The rear box plate 14 of the box body 11 is provided with a through hole 141, and the rotating part 513 of the rotating member extends from the through hole 141, so that the user can rotate it manually from the outside of the box body when in use. When in use, the first switch 51 and the second switch 52 are continuously screwed, so that the puncture needle moves toward the end of the carbon dioxide cylinder and gradually contacts the puncturable surface thereof, and finally causes the carbon dioxide cylinder to release gas.

[0047] The main body of the gas generator is cylindrical, and the following design is made for easy fixation. A support plate 6 is provided inside the left box plate 13, and the support plate 6 is bonded to the left box plate 13. An arc-shaped support groove is provided on the upper side of the support plate 6 along its length direction for the gas generator to be placed, and the two are also bonded. One end of the support plate 6 has an upwardly folded limit plate, which serves as a limit part 61, and is used to limit the tail of the gas generator, because when the gas generator is opened, force is applied from its front side.

[0048] In other embodiments, a rectangular carbon dioxide cylinder can also be customized. Since its side surface is flat, it is convenient for bonding and fixing. In this case, the support plate 6 can be omitted.

[0049] The first plastic bag film 31 and the second plastic bag film 32 are both in a folded state when not filled. The plastic bag film can be folded into a long strip by folding multiple sections in sequence, and can be temporarily fixed to the inner wall of the box body 11 with tape in the folded state. In fact, the first plastic bag film 31 and the second plastic bag film 32 are in a naturally deflated state without being deliberately folded and placed in the box body, which does not affect the final inflation use.

[0050] In other embodiments, a gas generator, i.e., a small carbon dioxide cylinder, may also be used, and a switch may be used, wherein the gas outlet of the switch is connected to the first gas pipe and the second gas pipe at the same time, and when the small carbon dioxide cylinder is turned on by the switch, the remaining gas released is simultaneously filled into the first plastic bag film and the second plastic bag film.

[0051] Embodiment 2:

[0052] like Figure 6-Figure 7 As shown, the main difference from Example 1 lies in the structure of the first and second gas generators and the principle of generating gas, as well as the structure of the first switch and the second switch; the first and second gas generators generate gas by chemical reaction, and the opening method of the switch is also similar to Example 1 outside the box. Take the first gas generator 21 and the first switch 51 on the lower side as an example, the structure and position of the first plastic bag film remain unchanged; the second gas generator, the second plastic bag film, and the second switch have the same structure and principle, which will not be repeated.

[0053] The first gas generator 21 is a rectangular container as a whole, and one side wall thereof is fixed to the inner side of the left box plate 13. One end of the gas outlet of the first gas generator 21 is close to the rear box plate 14 of the box body, and the rear box plate 14 is provided with a through hole 141. A part of the first switch 51 connected to the first gas generator 21 can pass through the through hole 141.

[0054] The first gas generator 21 includes a first cavity 212 and a second cavity 213. The second cavity 213 is located in the first cavity 212. The first cavity 212 is used to contain a first reaction substance, which is a powdered substance. The first cavity 212 is a rectangular box structure, and an exhaust pipe 214 is provided at one end, and the exhaust pipe 214 is connected to the inside of the first cavity.

[0055] The second cavity 213 is used to hold the second reaction substance, which can react chemically with the first reaction substance to produce gas, and the second reaction substance is a liquid substance. The second cavity 213 adopts a semi-cylindrical structure, with a sealing edge on the upper side, and is embedded in the installation opening of the first cavity 212. The first cavity 212 and the second cavity 213 can be fixed by gluing and sealed at the same time. The first cavity 212 and the second cavity 213 are both made of existing plastic materials, which are low-cost and easy to manufacture.

[0056] The two ends of the second cavity 213 have different diameters, one end is large and the other end is small, the large end faces the side of the first switch, and the large end uses tin foil sealing paper as a sealing material, so that it can be opened by using the first switch; other embodiments can also use existing plastic sealing films. Since one end of the second cavity 213 is high and the other end is low, after one end is opened, the second reaction substance can flow out directly and fall into the first cavity 212, thereby mixing and reacting with the first reaction substance.

[0057] The type of the second reactant corresponds to that of the first reactant. If the first reactant is manganese dioxide, then the second reactant is hydrogen peroxide, i.e., hydrogen peroxide, and the reaction between the two can produce oxygen; if the first reactant is sodium bicarbonate, then the second reactant is hydrochloric acid, and the reaction between the two can produce carbon dioxide.

[0058] The first switch 51 is a rotating part, including a rotating portion 513 and a first connecting portion 511. The first connecting portion 511 is threadedly connected to the exhaust pipe 214. A needle is provided at the end of the first connecting portion 511. The needle is a conical portion 5112, which can be used to pierce the tin foil sealing paper on one side of the second cavity 213 when the rotating portion rotates to allow the liquid substance therein to flow out.

[0059] A pipe joint 215 is vertically provided on the exhaust pipe 214, which is connected to the first air pipe. The first air pipe is made of a hose and can be made together with a plastic bag film as a component. Then, during assembly, the first air pipe is connected to the pipe joint on the exhaust pipe. The first connecting portion 511 of the first switch 51 is a diameter-reducing section, the threaded section is a large diameter section, and the small diameter section 5113 is near the end of the needle, so that there is a gap between the small diameter section 5113 and the inner hole of the exhaust pipe 214, which can be connected to the pipe joint. When the first reactant and the second reactant undergo a chemical reaction to produce gas, the gas is as follows. Figure 6 As shown by the middle arrow, the gas passes through the gap between the first connection portion of the first switch and the exhaust pipe, enters the pipe joint, and then enters the first plastic bag film through the first air pipe to achieve the purpose of gas filling. In order to make the liquid substance in the second cavity 213 flow out more smoothly, when the first switch is turned and gas is found to be generated, it can also be turned in the opposite direction to make it exit a little.

[0060] The method for making an integrated packaging box that automatically fills gas of the present invention is designed with a special gas generator that matches the size of the box, and a plastic bag film, which are prefabricated in the box; when it is used for packaging in the later stage, the gas generator can be easily activated, and the gas is quickly filled into the plastic bag film to form a cushion, which is very convenient to use, has few operating steps, saves time, and does not rely on experience (the size of the plastic bag film is adapted to the box, and the gas generator is disposable). The gas generator and the plastic bag film are provided in two groups, upper and lower, to wrap the upper and lower sides of the items respectively, to improve the pressure resistance and shock absorption in logistics transportation. This packaging box is not only suitable for companies, but also for families. You can buy cartons of the required size in advance for use, which is very convenient to use.
