Description

Insulated and cool packaging boxes that can be packaged without tape

[0001] The present invention relates to a packaging box for heat preservation and cold storage that can be packaged without tape, and more specifically, it comprises a side plate, a half upper plate, a lower plate, a side upper and lower folding support plate, and an upper and lower fitting assembly plate, so that the work of quickly sealing and packaging the opened upper and lower parts can be easily accomplished simply by assembling the upper and lower fitting assembly plates through the fitting assembly structure of the upper and lower fitting assembly plates without a separate taping work, and at the same time, when folding by the side assembly folding line of the side and upper and lower folding support plates, it has a support structure that forms a mountain shape with a flat damage prevention part of a certain length with respect to the tip end, and at the same time, an anti-lifting bending line that forms a 'U' shape with an angled corner is further formed from the central area of ​​the side assembly folding line on the side and upper and lower folding support plates, thereby preventing the free end of the support structure formed when folding by the side assembly folding line of the side and upper and lower folding support plates from being lifted, thereby preventing interference with the contents when packaging the contents with respect to the tip end, thereby preventing the contents from bursting or This relates to a packaging box for heat preservation and cooling that can be packaged without tape, which can stably prevent damage such as tearing, and can not only keep the contents warm or cold during packaging and transportation, but also prevent corrosion or deterioration.

[0002] Packaging boxes, which are generally manufactured to store or transport agricultural, marine, and livestock products that require heat and cold insulation, are mostly manufactured and used using various materials such as paper, cardboard, and Styrofoam.

[0003] When a packaging box like this is made of Styrofoam, it can protect the contents stored inside from external impacts as well as provide waterproofing, heat preservation, and cold preservation effects. However, since the molded box body is compressed to maintain a certain volume to contain the contents, there is a problem in that it costs a lot of money to store and transport.

[0004] On the other hand, packaging boxes made of paper and cardboard have the advantage of being easy to manufacture and can be stored in an unfolded and stacked state and then simply assembled for use, which greatly reduces logistics costs. However, because they are made of paper, they have poor waterproofing properties, and their heat and cold insulation effects do not meet expectations. At the same time, they have the problem of not being able to properly protect the contents stored inside from external impacts.

[0005] Moreover, packaging boxes made of paper and cardboard have a problem of gaps forming at the bottom or sides after assembly through folding, and thus a process of sealing the gaps through attachment or taping at the bottom or sides is essential. In addition, there is a problem of moisture inside the box leaking out through the gaps at the bottom or sides.

[0006] To improve the problems described above, a "packaging box with a sealed structure" was developed as shown in Patent Document 1 (Korean Patent No. 10-2182587, registered on November 18, 2020).

[0007] The packaging box having the above-described sealed structure, as shown in Patent Document 1 (Korean Patent No. 10-2182587, registered on November 18, 2020), has four side plates (110) forming a perimeter in a development diagram forming a hexahedral box, and an adhesive portion (111) is protrudedly formed on one side thereof, and when the adhesive portion (111) is bonded and connected to form a hexahedral box among the side plates (110), the half upper and lower plates (120) (130) are formed to cover 1 / 2 of the upper and lower surfaces of the hexahedron when the side plates (110) are bonded and connected to the upper and lower sides of each of a pair of side plates (110) that are opposed to each other, and when the adhesive portion (111) is bonded and connected to form a hexahedral box among the side plates (110), the half upper and lower plates (120) (130) are connected to the upper and lower sides of each of the other pair of side plates (110) that are opposed to each other, and at the same time, The configuration is such that both sides are connected to the side ends of the half-upper and lower plates (120)(130), and a triangular side assembly folding line (220) is formed so that when folding inward from another pair of side plates (110) along this, the half-upper and lower plates (120)(130) are folded simultaneously, and the side upper and lower folding support plates (140)(150) that form a support structure for the upper and lower interiors together with the half-upper and lower plates (120)(130) are respectively connected, and a folding line (210) is formed at the mutually connected portion of the side plate (110), the half-upper and lower plates (120)(130), and the side upper and lower folding support plates (140)(150), and after the side plates (110) are joined and connected, when the upper and lower parts are packed and sealed, they are folded along the folding line (210) and the side assembly folding line (220). In a packaging box having a sealed structure in which the upper and lower folding support plates (140) (150) are folded at the same time as the half upper and lower plates (120) (130) are folded, the facing ends of the half upper and lower plates (120) (130) are brought into close contact so that the upper and lower parts opened by the joint connection of the side plates (110) are sealed, and then the facing and closely contacted ends of the half upper and lower plates (120) (130) are taped with tape (T) to complete the packaging and sealing work, the side upper,When bonding and connecting the adhesive portion (111) to form a hexahedral box among the side plates (110) for the lower folding support plate (140)(150), the upper and lower sides of the other pair of side plates (110) that are opposite each other are connected to each other, and at the same time, both sides can be connected to the side ends of the half-upper and lower plates (120)(130), so that the side ends of the half-upper and lower plates (120)(130) that are connected to the upper and lower sides of the side plate (110) that has the adhesive portion (111) among the side plates (110) are formed with the upper and lower adhesive portions (121)(131) protruding further in correspondence with the adhesive portion (111), while the upper and lower adhesive portions (121)(131) are formed on the side ends of the side upper and lower folding support plates (140)(150) when bonding and connecting the adhesive portion (111) to form a hexahedral box. When the upper and lower folding support plates (140) (150) are folded toward the inside from another pair of side plates (110) with respect to the upper and lower adhesive portions (121) (131) and the half upper and lower plates (120) (130) are folded simultaneously, the upper and lower folding support plates (140) (150) and the upper and lower adhesive portions (121) (131) are joined and connected to each other, so that smooth folding can be achieved for the portion where the two plates are overlapped, the line where the upper and lower adhesive portions (121) (131) of the adhesive portion (111) are connected is slitted by a certain width with an inclination corresponding to the side assembly folding line (220), thereby forming a folding slit (S), and when packaging and sealing the packaging box (10), the half upper and lower plates (120) (130) and On the surface located on the packaging space side of the upper and lower folding support plates (140)(150), aluminum-deposited PET, PP, OPP, CPP film and KLB raw paper or PET, PE, PP, OPP, CPP film are selected and attached integrally.

[0008] According to the conventional packaging box as described above, the upper and lower sides can be easily pushed inward, and the upper and lower sides can be sealed through a single fold, and then the packing and sealing can be completed by taping, thereby enabling rapid packing and sealing.

[0009] In addition, by selecting one of PET, PP, OPP, CPP film and KLB paper with aluminum deposited on the inner surface of the packaging box or PET, PE, PP, OPP, CPP film and attaching them together as one body, it is possible to prevent the contents from being spoiled or corroded as well as to keep the contents warm or cold during transportation of the contents.

[0010] However, the conventional packaging box as described above essentially requires the work of taping the opposing free ends of the upper and lower half plates by folding the side and upper and lower folding support plates, and accordingly, there was a problem in that the process of taping while maintaining the opposing free ends of the upper and lower half plates in a state of facing each other during the sealing work on the upper and lower parts was not easily performed.

[0011] In addition, when folding by the side assembly folding line of the side, upper and lower folding support plates, a phenomenon occurs in which the sharp tip that is folded into a triangular plate shape is lifted in the folding direction, and there is a problem in which the sharp tip is lifted in the folding direction, causing damage such as bursting or tearing of the contents due to interference between the contents and the tip when packaging the contents.

[0012] Therefore, it is possible to easily quickly seal and package the open upper and lower parts with only assembly without separate taping work, and at the same time, it prevents the sharp tip that is folded into a triangular plate shape when folded by the side assembly folding line of the side and upper and lower folding support plates from being lifted, thereby preventing interference between the tip and the contents during packaging, thereby stably preventing damage such as bursting or tearing of the contents, and research and development are required for a packaging box for heat preservation and cooling that can be packaged without tape so that the contents can be kept warm or cold during packaging and transport, as well as prevent corrosion or deterioration.

[0018] (Patent Document 5) Republic of Korea Public Utility Model No. 1999-000502, published on January 15, 1999.

[0019] In order to solve the above problems, the present invention provides a packaging box for heat preservation and cold storage that can be packaged without tape, which includes a side plate, a half-upper and lower plate, a side upper and lower folding support plate, and an upper and lower fitting assembly plate, so that the work of quickly sealing and packaging the opened upper and lower parts can be easily accomplished simply by assembling the upper and lower fitting assembly plates through the fitting assembly structure of the upper and lower fitting assembly plates without a separate taping work.

[0020] Another object of the technology according to the present invention is to have a support structure that forms a mountain shape with a flat damage prevention portion of a certain length at the tip end when folded by the side assembly folding line of the side and upper and lower folding support plates, and at the same time, an anti-lifting bending line that forms a 'U' shape with sharp corners is further formed from the central area of ​​the side assembly folding line on the side and upper and lower folding support plates, thereby preventing the free end of the support structure formed when folded by the side assembly folding line of the side and upper and lower folding support plates from being lifted, thereby preventing interference with the contents when packaging the contents with respect to the tip end, unlike the prior art, and stably preventing damage such as bursting or tearing of the contents, and not only keeping the contents warm or cold, but also preventing corrosion or deterioration of the contents when packaging and transporting the contents.

[0021] Another object of the technology according to the present invention is to manufacture a packaging box including a side plate, a half-upper and lower plate, a side upper and lower folding support plate, and an upper and lower fitting assembly plate using corrugated cardboard, and to manufacture the box using corrugated cardboard so that the direction in which the mountain and valley repeats correspond to the up-down direction of the side plate, thereby minimizing the tension restoring force that tries to return to the original state when the valley part is folded when folding along the folding line, and to make folding and fitting assembly easier.

[0022] In order to achieve the above-mentioned object, the present invention is as follows. That is, the present invention provides a heat-insulating and cold-insulating packaging box that can be packaged without a tape, which can be quickly sealed and packaged for an open top and bottom by simply assembling a hexahedral fitting structure without a separate taping operation, the heat-insulating and cold-insulating packaging box comprising: a development drawing forming a hexahedral box, wherein: a side plate provided in the form of four plates to form a perimeter of the hexahedron and having an adhesive portion protruding on one side thereof; a half upper and lower plate that are connected to the upper and lower sides of each of a pair of side plates that face each other when the adhesive portions are bonded and connected to form a hexahedral box among the side plates so as to cover half of the upper and lower surfaces of the hexahedron when the side plates are bonded and connected; When bonding and connecting the adhesive portion to form a hexahedral box among the above side plates, the upper and lower sides of another pair of mutually opposing side plates are respectively connected, and at the same time, both sides are connected to the side ends of the half-upper and lower plates, so that a mountain-shaped side assembly folding line is formed, and when folding inward from another pair of side plates along this, the half-upper and lower plates are folded simultaneously, and the side upper and lower folding support plates form a support structure for the inside of the upper and lower sides together with the half-upper and lower plates; a folding line formed at the mutually connecting portion of the side plates, the half-upper and lower plates, and the side upper and lower folding support plates; And, in order to enable sealing through assembly with a fitting structure without tape when packaging and sealing the upper and lower parts while the side plates are connected and joined, it is formed by extending a certain length from one of the facing half upper and lower plates, and is composed of an upper and lower fitting assembly plate that is fitted into a gap formed by the other facing half upper and lower plate and the side upper and lower folding support plate.

[0023] At this time, it is preferable that the upper and lower fitting assembly plates are further formed with a fitting guide bend line at a certain distance from the extended end of the half upper and lower plates toward the half upper and lower plates so that the upper and lower fitting assembly plates can be easily fitted into the gap formed by the other facing side upper and lower folding support plates and the half upper and lower plates.

[0024] Furthermore, it is preferable that the upper and lower fitting assembly plates are further formed with slanted fitting guide portions facing each other on both sides of the extended ends in the width direction of the upper and lower fitting assembly plates so that they can be easily guided into the gap formed by the other one of the upper and lower folding support plates and the half upper and lower plates on both sides of the free ends, and have a narrow width from the fitting guide bend line toward the extended ends.

[0025] In addition, it is preferable that the side assembly folding line be formed in a mountain shape with a flat breakage prevention portion of a certain length at the center of the upper end of the side upper and lower folding support plates.

[0026] In addition, it is preferable to further form an anti-lifting bending line that extends horizontally in the upper and lower central area of ​​the side assembly cutting line and then extends upward from both ends to the upper end of the upper and lower side folding support plates to form a 'U' shape with sharp corners.

[0027] And, for the upper and lower folding support plates, when bonding and connecting the adhesive portions to form a hexahedral box among the side plates, it is preferable that the upper and lower adhesive portions are formed to protrude further in correspondence with the adhesive portions on the side ends of the half upper and lower plates connected to the upper and lower sides of the side plates on which the adhesive portions are provided so that both sides can be connected to the side ends of the half upper and lower plates, while the upper and lower adhesive portions are bonded and connected to the side ends of the upper and lower folding support plates when bonding and connecting the adhesive portions to form a hexahedral box.

[0028] Furthermore, when the upper and lower folding support plates are folded toward the inside from another pair of side plates for the upper and lower adhesive portions and the half upper and lower plates are folded simultaneously, it is preferable that a certain area be cut at the portion where the adhesive portion and the upper and lower adhesive portions are connected so that smooth folding can be achieved for the portion where the upper and lower folding support plates and the upper and lower adhesive portions are overlapped as two plates, and that the upper and lower adhesive portions are formed with a folding guide slope corresponding to the slope of the side assembly folding line on the upper and lower folding support plates to be joined at the cut-processed end adjacent to the adhesive portions.

[0029] The effects of the thermal insulation and cooling packaging box capable of packaging without tape according to the present invention are as follows.

[0030] First, by including a side plate, a half-upper and lower plate, a side upper and lower folding support plate, and an upper and lower fitting assembly plate, the upper and lower fitting assembly plate's fitting assembly structure without separate taping work allows for a quick sealing and packaging operation for the open upper and lower parts simply by assembling.

[0031] Second, when folded along the side assembly folding line of the side and upper and lower folding support plates, a support structure having a mountain shape with a flat, breakage-preventing portion of a certain length is formed relative to the tip, and at the same time, a lifting-prevention bending line having a sharp 'U' shape is further formed from the central area of ​​the side assembly folding line on the side and upper and lower folding support plates, thereby preventing the free end of the support structure formed when folded along the side assembly folding line of the side and upper and lower folding support plates from being lifted, thereby preventing interference with the contents during packaging of the contents at the tip, unlike in the past, and stably preventing damage such as bursting or tearing of the contents, and when packaging and transporting the contents, it is possible to not only keep the contents warm or cold, but also prevent corrosion or deterioration.

[0032] Third, the packaging box including the side plate, the half-upper and lower plates, the side upper and lower folding support plates, and the upper and lower fitting assembly plates is manufactured from corrugated cardboard, and the direction in which the mountain and valley repeats is aligned with the up-down direction of the side plate, thereby minimizing the tension restoring force that tries to return to the original state when the valley part is folded when folding along the folding line, and making folding and fitting assembly easier.

[0035] Figures 3 to 8 are assembly use state examples showing the assembly process for sealing packaging of a heat-insulating and cold-insulating packaging box that can be packaged without tape according to the present invention, step by step.

[0036] Hereinafter, with reference to the attached drawings, a preferred embodiment of a packaging box for heat preservation and cooling that can be packaged without tape according to the present invention will be described in detail.

[0037] Figure 1 is a development diagram showing a packaging box for heat preservation and cooling that can be packaged without tape according to the present invention.

[0038] Fig. 2 is a perspective view showing a packaging box for insulation and cooling that can be packaged without tape according to the present invention, and showing a structure in which side plates are bonded and connected before assembly for packaging.

[0039] Figures 3 to 8 are assembly use state examples showing the assembly process for sealing packaging of a heat-insulating and cold-insulating packaging box that can be packaged without tape according to the present invention, step by step.

[0040] As shown in FIGS. 1 to 8, a heat-insulating and cold-insulating packaging box (100) capable of being packaged without tape according to a preferred embodiment of the present invention is a box that is manufactured from a single piece of cardboard and can be quickly sealed and packaged for the open top and bottom by simply assembling it through a hexahedral fitting structure without a separate taping operation after bonding and connecting the adhesive portion (111) of the side wall (110).

[0041] A packaging box (100) for insulation and cooling that can be packaged without tape according to a preferred embodiment of the present invention can be broadly classified to include a side plate (110), a half upper and lower plate (120)(130), a side upper and lower folding support plate (140)(150), a folding line (210), and an upper and lower fitting assembly plate (120')(130').

[0042] Specifically, the side plate (110) is a development diagram forming a hexahedral box, and is provided in the form of four plates to form the perimeter of the hexahedron, with an adhesive portion (111) protrudingly formed on one side thereof.

[0043] And the above half-upper and lower plates (120) (130) are connected to the upper and lower sides of each of a pair of side plates (110) that are opposed to each other when bonding and connecting the adhesive portion (111) to form a hexahedral box among the side plates (110), so that they are formed to cover 1 / 2 of the upper and lower surfaces of the hexahedron when bonding and connecting the side plates (110).

[0044] In addition, the upper and lower folding support plates (140)(150) are configured such that when the adhesive portion (111) is bonded to form a hexahedral box among the side plates (110), they are connected to the upper and lower sides of another pair of side plates (110) facing each other, and at the same time, both sides are connected to the side ends of the upper and lower half plates (120)(130).

[0045] These upper and lower folding support plates (140)(150) are formed with a mountain-shaped side assembly folding line (220), and when folded inward from another pair of side plates (110) along this line, the upper and lower plates (120)(130) are folded simultaneously, thereby forming a support structure for the upper and lower interiors together with the upper and lower plates (120)(130).

[0046] In addition, the above folding line (210) is formed at the interconnected portion of the side plate (110), the half upper and lower plates (120) (130), and the side upper and lower folding support plates (140) (150).

[0047] And the upper and lower fitting assembly plates (120') (130') are assembled in a fitting structure without tape during packaging and sealing of the upper and lower parts while the side plates (110) are connected and joined, so that they can be sealed.

[0048] The upper and lower fitting assembly plates (120') (130') as described above are formed by extending a certain length from one of the facing upper and lower half plates (120) (130) and are fitted into a gap formed by the side upper and lower folding support plates (140) (150) and the other facing one of the upper and lower half plates (120) (130).

[0049] In other words, the upper and lower fitting assembly plates (120') (130') formed by extending a certain length from one of the half upper and lower plates (120) (130) facing each other are folded along the folding line (210) and the side assembly folding line (220) after the side plates (110) are joined and connected, and the upper and lower folding support plates (140) (150) are folded while the half upper and lower plates (120) (130) are folded, and in the process of the facing ends of the half upper and lower plates (120) (130) being brought into close contact, the other of the side upper and lower folding support plates (140) (150) and the half upper and lower plates (120) (130) It is assembled by fitting into the gap formed by the half-upper and lower plates (120)(130).

[0050] In addition, it is important to make it easy to assemble the upper and lower fitting assembly plates (120')(130') as described above by fitting them into the gap formed by the upper and lower folding support plates (140)(150) and the other facing one of the half upper and lower plates (120)(130).

[0051] To this end, it is preferable that the upper and lower fitting assembly plates (120') (130') further have a fitting guide bend line (121') (131') formed at a position a certain distance away from the extended end of the half upper and lower plates (120) (130) toward the half upper and lower plates (120) (130).

[0052] It is also important that the upper and lower fitting assembly plates (120')(130') as described above are particularly easy to fit together in two stages with the fitting guide bend line (121')(131') in the gap formed by the other facing side upper and lower folding support plates (140)(150) and the half upper and lower plates (120)(130).

[0053] Accordingly, an auxiliary fitting guide bending line (122') (132') can be further formed at a certain distance from the connecting end, which is the end that is extended from the half upper and lower plates (120) (130) of the upper and lower fitting assembly plates (120') (130').

[0054] In addition, it is important that the upper and lower fitting assembly plates (120') (130') can be easily guided into the gap formed by the upper and lower folding support plates (140) (150) and the other half upper and lower plates (120) (130) on both sides of the free end.

[0055] To this end, it is more preferable that the insertion guide portions (123') (133') are formed so as to have a narrow width from the insertion guide bend line (121') (131') toward the extension end, facing each other on both sides in the width direction of the extension end of the upper and lower insertion assembly plates (120') (130').

[0056] Meanwhile, in the tape-free heat-insulating and cold-insulating packaging box (100) according to the present invention having the configuration described above, it is preferable that the side assembly folding line (220) be formed in a mountain shape having a flat damage prevention portion (141) (151) of a certain length at the upper center of the side upper and lower folding support plates (140) (150).

[0057] In other words, as described above, the side assembly folding line (220) is formed to have a mountain shape with a flat damage prevention portion (141)(151) of a certain length at the upper center of the side upper and lower folding support plates (140)(150), so that the half upper and lower plates (120)(130) are folded simultaneously toward the inside from another pair of side plates (110) with respect to the side upper and lower folding support plates (140)(150), and when forming a support structure for the inside of the upper and lower sides together with the half upper and lower plates (120)(130), the tip of the support structure can be blunt.

[0058] In addition, an anti-lifting bending line (221) may be further formed by extending horizontally in the upper and lower central area of ​​the side assembly cutting line (220) and then extending upward from both ends to the upper ends of the upper and lower folding support plates (140) (150) to form a 'U' shape with sharp corners.

[0059] That is, when an anti-lifting bending line (221) is further formed that extends horizontally in the vertical central area of ​​the side assembly cutting line (220) as described above and then extends upward from both ends to the upper ends of the upper and lower folding support plates (140)(150) to form a 'U' shape with sharp corners, the phenomenon of the free end of the support structure being lifted can be prevented when the half upper and lower plates (120)(130) are folded simultaneously from another pair of side plates (110) toward the inside with respect to the side upper and lower folding support plates (140)(150) to form a support structure for the inside of the upper and lower sides together with the half upper and lower plates (120)(130).

[0060] According to the present invention, a heat-insulating and cold-insulating packaging box (100) that can be packaged without tape and has a configuration as described above, when bonding and connecting the adhesive portion (111) to the side plates (110) to form a hexahedral box with respect to the upper and lower folding support plates (140) (150), it is important that the upper and lower sides of a pair of mutually opposing side plates (110) are connected to each other, and at the same time, both sides can be connected to the side ends of the half upper and lower plates (120) (130).

[0061] Accordingly, upper and lower adhesive portions (121) (131) can be formed to protrude further on the side ends of the half upper and lower plates (120) (130) connected to the upper and lower sides of the side plate (110) having the adhesive portion (111) among the side plates (110) to correspond to the adhesive portion (111).

[0062] At this time, it is preferable that the upper and lower adhesive parts (121)(131) are connected to the side ends of the upper and lower folding support plates (140)(150) when connecting the adhesive part (111) to form a hexahedral box.

[0063] Moreover, when the upper and lower folding support plates (140) (150) are folded toward the inside from another pair of side plates (110) for the upper and lower adhesive portions (121) (131) and the half upper and lower plates (120) (130) are folded simultaneously, it is important to ensure that the upper and lower folding support plates (140) (150) and the upper and lower adhesive portions (121) (131) are connected and joined so that smooth folding can be achieved for the portion where the two plates overlap.

[0064] Therefore, a certain area is cut at the part where the above-mentioned adhesive portion (111) and the upper and lower adhesive portions (121)(131) are connected, and in particular, it is more preferable that the upper and lower adhesive portions (121)(131) are formed with a folding guide slope (S) inclined to correspond to the slope of the side assembly folding line (220) on the upper and lower folding support plates (140)(150) to be joined to the cut end adjacent to the adhesive portion (111).

[0065] In addition, in the present invention, a packaging box (100) for insulation and cooling that can be packaged without tape, having a configuration as described above, it is preferable that, when packaging and sealing the packaging box (100), the side plate (110), the half upper and lower plates (120) (130), and the upper and lower side folding support plates (140 (150)) are positioned on the packaging space side, one of aluminum-deposited PET, PP, OPP, CPP film and KLB base paper, or PET, PE, PP, OPP, CPP film is selected and attached integrally.

[0066] Furthermore, the packaging box (100) for insulation and cooling that can be packaged without tape according to the present invention having the configuration as described above can be cured by applying a certain thickness of an anti-rust agent, a water- and oil-resistant eco-friendly coating agent, or paraffin to the surface located on the packaging space side of the side plate (110), the half upper and lower plates (120) (130), and the side upper and lower folding support plates (140) (150) during the packaging and sealing operation of the packaging box (100).

[0067] In addition, the heat-insulating and cold-insulating packaging box (100) according to the present invention, which can be packaged without tape and has a configuration as described above, is preferably manufactured from a paper-based board or corrugated cardboard, and of course, can be manufactured from various types such as a plastic-based board or a non-woven fabric having strength.

[0068] For example, in the case where a packaging box (100) for insulation and cooling that can be packaged without tape according to the present invention is manufactured from corrugated cardboard, it is more preferable to manufacture the packaging box (100) including a side plate (110), half upper and lower plates (120)(130), upper and lower side folding support plates (140)(150), and upper and lower fitting assembly plates (120')(130') from corrugated cardboard, and to manufacture it from corrugated cardboard so that the direction in which the mountains and valleys are repeated matches the up-down direction of the side plate (110).

[0069] That is, when manufacturing a packaging box (100) including a side plate (110), half upper and lower plates (120) (130), upper and lower side folding support plates (140) (150), and upper and lower fitting assembly plates (120') (130') as described above, by manufacturing the box with cardboard so that the direction in which the mountains and valleys are repeated corresponds to the up-down direction of the side plate (110), the tension restoring force that causes the valley portion to fold and return to its original state when folded when folded along the folding line (210) is minimized, thereby making folding and fitting assembly easier.

[0070] In addition, the heat and cold insulation packaging box (100) according to the present invention, which is configured as described above and can be packaged without tape, is configured so that when the adhesive portion (111) protrudingly formed on one side of the side plate (110) is bonded to form a hexahedral box, the upper and lower half plates (120) (130) and the free ends of the upper and lower side folding support plates (140) (150) that extend upward and downward in the packaging space formed by the side plate (110) can be at the same height.

[0071] For this purpose, it is preferable that the length from the folded end of the upper and lower half plates (120)(130) to the free end and the length from the folded end of the upper and lower side folding support plates (140)(150) to the free end be provided as the same length.

[0072] According to the present invention, a packaging box for heat preservation and cooling that can be packaged without tape, having a configuration as described above, comprises a side plate, a half upper plate, a lower plate, a side upper plate, a lower folding support plate, and an upper and lower fitting assembly plate, so that the work of quickly sealing and packaging the opened upper and lower parts can be easily accomplished simply by assembling the upper and lower fitting assembly plates through the fitting assembly structure without a separate taping work.

[0073] In addition, when folded along the side assembly folding line of the side and upper and lower folding support plates, a support structure having a mountain shape with a flat damage prevention portion of a certain length is formed relative to the tip, and at the same time, a lifting prevention bending line having a 'U' shape with sharp corners is further formed from the central area of ​​the side assembly folding line on the side and upper and lower folding support plates, thereby preventing the free end of the support structure formed when folded along the side assembly folding line of the side and upper and lower folding support plates from being lifted, thereby preventing interference with the contents during packaging of the contents at the tip, unlike in the past, and stably preventing damage such as bursting or tearing of the contents, and when packaging and transporting the contents, it is possible to not only keep the contents warm or cold, but also prevent corrosion or deterioration.

[0074] Furthermore, the packaging box including the side plate, the half-upper and lower plates, the side upper and lower folding support plates, and the upper and lower fitting assembly plates is manufactured from corrugated cardboard, and the direction in which the mountain and valley repeats is aligned with the up-down direction of the side plate, thereby minimizing the tension restoring force that tries to return to the original state when the valley part is folded when folding along the folding line, thereby making folding and fitting assembly easier.

[0075] Although specific embodiments of the present invention have been described in detail above, the present invention is not limited thereto, and various modifications can be made by a person having ordinary skill in the art to which the present invention pertains, and such modifications are included within the scope of the present invention.
