A wine bottle packaging box and a folding method thereof

Abstract

This invention belongs to the technical field of wine bottle packaging boxes, specifically relating to a wine bottle packaging box and its folding method. It includes a bottom plate, a top plate, and side panels connecting the bottom and top plates. A fixed support assembly is installed on the bottom plate, comprising several support plates, each with a placement groove. The first support plate is connected to the bottom plate. A slotted box is installed on the side panels. During the sealing process, the fixed support assembly is pulled up, causing the support plates to gradually unfold into a corrugated structure. The two ends of the placement groove are inclined and engage with the bottle wall. Because the fixed support assembly itself has a corrugated structure, it provides lateral support to the side panels. When the packaging box is subjected to lateral compression during transportation, the fixed support assembly effectively prevents the side panels from deforming under pressure, thus improving the strength of the packaging box.

Description

Technical Field

[0001] This invention belongs to the technical field of wine bottle packaging boxes, and specifically relates to a wine bottle packaging box and its folding method. Background Technology

[0002] Wine bottle packaging boxes are divided into paper boxes, leather boxes, metal boxes, and wooden boxes, among which paper wine bottle packaging boxes occupy a major position in wine box packaging materials due to their advantages such as being lightweight, having excellent printing and processing performance, and being easy to recycle.

[0003] Existing bottle packaging boxes can protect the bottle neck and bottom. After the bottle is placed in the box, the box can protect the bottle neck and bottom, preventing them from being bumped or damaged. For example, Chinese patent CN105966718B uses a base support and neck retainer to protect the bottle neck and bottom. However, the bottle wall is only protected by a single layer of sidewalls on the box. During transportation, if the bottle packaging box is hit from the side, the sidewalls are easily deformed, causing the bottle's sidewalls to break. In this process, the box cannot effectively protect the bottle's sidewalls. The above problems can be solved by inserting foam packaging between the bottle and the box. The foam packaging can fit the bottle and the box, thus protecting the side wall of the bottle. However, when removing the bottle from the box, the foam packaging has an uneven surface, resulting in a large friction between the foam packaging and the box. This makes it very difficult to remove the bottle and it is easy to drop it, causing the bottle to break. Therefore, inserting foam packaging is not convenient for practical use. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a wine bottle packaging box and its folding method, thereby solving the technical problems in the prior art.

[0005] The objective of this invention can be achieved through the following technical solution: a wine bottle packaging box, comprising a bottom plate, a top plate, and a side plate wall connecting the bottom plate and the top plate, wherein a fixed support assembly is installed on the bottom plate, the fixed support assembly comprising a plurality of support plates, the plurality of support plates being connected to each other, each of the plurality of support plates having a placement groove, the support plate at the first end being connected to the bottom plate, the support plate at the last end being installed with a fixed pressing plate, a plate groove box being installed on the side plate wall, the fixed pressing plate being inserted into the plate groove box, and the top plate pressing the fixed pressing plate and installing it with the side plate wall;

[0006] When packaging the wine bottle, several support plates are folded, then the wine bottle is passed through the placement slot and placed on the bottom plate. Then the fixed support assembly is pulled up, and the fixed pressing plate is inserted into the plate slot box. Next, the top plate is flipped over so that the top plate presses against the fixed pressing plate. Finally, the top plate is fixed to the side plate wall.

[0007] As a further optimization or improvement to this solution, an extension plate is provided between two adjacent support plates, and a gap is reserved between the extension plate and the side plate wall.

[0008] As a further optimization or improvement to this solution, the top plate includes a reinforcing plate, on which a protective sleeve is installed, and the protective sleeve covers the mouth of the wine bottle.

[0009] As a further optimization or improvement to this solution, the top plate also includes a pressure block, which presses and fixes the pressure plate.

[0010] As a further optimization or improvement of this solution, the plate slot box includes an installation slot with the opening facing upward. A fixed pressing plate is inserted into the installation slot. A hook groove is provided on the installation slot. A tear strip is provided on the fixed pressing plate and is located in the hook groove. An anti-counterfeiting component is installed on the top plate and is snapped into the bottom of the tear strip.

[0011] As a further optimization or improvement of this solution, the anti-counterfeiting component includes a hook, and the top plate is connected to the hook via a connecting plate, with the hook hooking onto the bottom of the tear strip.

[0012] As a further optimization or improvement of this solution, two threading holes are respectively opened on the top plate and the side plate wall, and a ribbon is passed through the two threading holes to fix the top plate to the side plate wall.

[0013] A method for folding a wine bottle packaging box, the method being applied to the wine bottle packaging box as described above, the method comprising the following steps:

[0014] Step S1: Fold several support plates together, then fold the bottom plate so that the bottom plate is perpendicular to the side wall.

[0015] Step S2: Fold the side panel wall so that it wraps around the bottom plate. Then, place the bottle through the placement slot onto the bottom plate. Then, pull up the fixing support assembly. Several support plates gradually unfold, so that the support plates gradually form a corrugated plate structure. At this time, the two ends of the placement slot gradually tilt and engage with the bottle wall. Then, insert the fixing pressing plate at the end of the fixing support assembly into the plate slot box, and then fix the side panel wall onto the bottom plate.

[0016] Step S3: Flip the top plate, and the pressure block on the top plate presses against the fixed pressing plate. At this time, the fixed support assembly and the wine bottle on it are fixed inside the packaging box.

[0017] As a further optimization or improvement of this solution, step S2 specifically includes the following steps:

[0018] Step S21: Insert the fixing press plate into the mounting slot so that the tear strip on the fixing press plate is in the hook slot. Then flip the top plate. As the top plate rotates, the hook on the top plate hooks the bottom of the tear strip.

[0019] The beneficial effects of this invention are:

[0020] (1) During the packaging process of the present invention, the fixed support assembly is pulled up, and several support plates gradually unfold, making the support plates gradually form a corrugated structure. At this time, the two ends of the placement slot are inclined and engage with the bottle wall. Then, the fixed pressing plate at the tail end of the fixed support assembly is inserted into the slot box, and then the fixed pressing plate is fixed by the top plate. At this time, the fixed support assembly and the bottle on it are fixed inside the packaging box, effectively preventing the bottle from shaking inside the packaging box during transportation. Since the fixed support assembly itself has a corrugated structure, the fixed support assembly can provide lateral support force to the side plate wall. When the packaging box is subjected to lateral compression during transportation, the fixed support assembly can provide strong lateral support force to the side plate wall, effectively preventing the side plate wall from being deformed by pressure and improving the strength of the packaging box itself.

[0021] (2) When removing the bottle from the packaging box, the top panel is opened, and the fixing pressing plate is removed from the slotted box. Then, the fixing support assembly is pressed down, causing several support plates to fold together. When the two ends of the placement slot on the support plate disengage from the side wall of the bottle, the bottle can be directly removed. When the bottle needs to be placed back into the packaging box for storage, the bottle is placed directly through the placement slot onto the bottom plate. Then, the fixing support assembly is pulled up, causing the placement slot to lock the bottle wall. Next, the fixing pressing plate is inserted into the slotted box, thus securing the bottle in the packaging box for storage. This solution uses the push-pull method to adjust the tightness of the fixing support assembly on the bottle, ensuring that the bottle can be easily removed.

[0022] (3) During the packaging process, after the fixing pressing plate is inserted into the mounting slot, the state of the tear strip can be observed through the hook groove. The top plate is then flipped, causing the pressing block to press and limit the fixing pressing plate. The top plate continues to flip, causing the hook on the top plate to hook the bottom of the tear strip. If the packaging box is opened, the top plate flips and drives the hook to tear the tear strip. Therefore, before opening the box, the buyer can determine whether the packaging box has been opened by observing whether the tear strip has been torn. This invention can determine whether the packaging box has been opened by observing the state of the tear strip, thereby ensuring the anti-counterfeiting function of the wine bottle packaging box.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] See Figures 1-7 A wine bottle packaging box includes a bottom plate 1, a top plate 2, and a side plate wall 3 connecting the bottom plate 1 and the top plate 2. A fixed support assembly 4 is installed on the bottom plate 1. The fixed support assembly 4 includes a plurality of support plates 41, which are connected to each other. Each of the support plates 41 has a placement groove 42. The first end support plate 41 is connected to the bottom plate 1, and the last end support plate 41 is equipped with a fixed pressing plate 44. A plate groove box 5 is installed on the side plate wall 3. The fixed pressing plate 44 is inserted into the plate groove box 5. The top plate 2 presses down on the fixed pressing plate 44 and is installed with the side plate wall 3.

[0035] When packaging the wine bottle, several support plates 41 are folded, then the wine bottle is passed through the placement slot 42 and placed on the base plate 1. Then the fixed support assembly 4 is pulled up, and the fixed pressing plate 44 is inserted into the plate slot box 5. Then the top plate 2 is flipped over so that the top plate 2 presses against the fixed pressing plate 44. Finally, the top plate 2 is fixed to the side plate wall 3.

[0036] It should be noted that, when folding this invention, several support plates 41 need to be folded first, such as... Figures 1-2 Next, fold the bottom plate 1 so that it is perpendicular to the side wall 3, as shown. Figures 2-3 Then fold the side panel 3 so that it covers the bottom plate 1. Next, place the bottle through the placement groove 42 onto the bottom plate 1. Then pull up the fixing support assembly 4 so that the placement groove 42 locks the bottle wall. Then insert the fixing pressing plate 44 into the plate groove box 5. Figure 5 Then fix the side panel 3 to the base plate 1, as follows: Figure 6 Finally, flip the top plate 2 so that it presses against the fixed pressing plate 44. At this time, the fixed support component 4 can fix the wine bottle in the packaging box to prevent the wine bottle from shaking in the packaging box during transportation and ensure the stability of the wine bottle.

[0037] It should be noted that the opening of the placement slot 42 is elliptical. During the process of pulling up the fixed support assembly 4, several support plates 41 gradually unfold, as... Figure 3 As shown, several support plates 41 are gradually made into a corrugated plate structure. At this time, the two ends of the placement groove 42 are gradually tilted and engaged with the bottle wall. Then, the fixing pressing plate 44 at the tail end of the fixing support component 4 is inserted into the plate groove box 5. Then, the fixing pressing plate 44 is fixed by the top plate 2. At this time, the fixing support component 4 and the bottle on it are fixed in the packaging box, effectively preventing the bottle from shaking in the packaging box during transportation. Because the fixed support component 4 has a corrugated structure, it can provide lateral support to the side wall 3. When the packaging box is subjected to lateral compression during transportation, the fixed support component 4 can provide strong lateral support to the side wall 3, effectively preventing the side wall 3 from being deformed by pressure and improving the strength of the packaging box itself. Compared with the existing technology of inserting foam packaging between the bottle and the packaging box, this invention improves the strength of the packaging box by supporting the side wall of the packaging box with the fixed support component 4, thereby achieving the purpose of protecting the bottle inside the packaging box. In contrast, the protection method of inserting foam packaging between the bottle and the packaging box can only protect the bottle inside the packaging box through the foam packaging, but cannot support the side wall of the packaging box. When subjected to lateral impact, the side wall of the packaging box in the above-mentioned existing technology cannot be effectively protected, which makes the packaging box easy to break, thus affecting the sales of the wine.

[0038] See Figure 7An extension plate 43 is provided between two adjacent support plates 41, and a gap is reserved between the extension plate 43 and the side plate wall 3.

[0039] It should be noted that an extension plate 43 is provided between the support plates 41. The extension plate 43 can increase the contact area between the fixed support component 4 and the side wall 3. When the packaging box is subjected to a lateral impact, more impact force can be transmitted to the fixed support component 4 through the extension plate 43, thereby effectively enhancing the support strength of the side wall 3.

[0040] It should be noted that when it is necessary to open the packaging box and take out the bottle, open the top panel 2, remove the fixing pressing plate 44 from the plate slot box 5, and then press down the fixing support assembly 4 to fold the support plates 41 together. When the two ends of the placement slot 42 on the support plate 41 are no longer in contact with the side wall of the bottle, the bottle can be taken out directly. The gap between the extension plate 43 and the side panel wall 3 provides folding space for the support plates 41. When it is necessary to put the bottle back into the packaging box for storage, simply place the bottle through the placement slot 42 onto the bottom plate 1, then pull up the fixing support assembly 4 to make the placement slot 42 lock the bottle wall, and then insert the fixing pressing plate 44 into the plate slot box 5. The bottle can then be fixed in the packaging box for storage by the fixing support assembly 4.

[0041] Compared to existing packaging boxes, the process of picking up and taking out wine bottles is extremely difficult because the surface of the foam packaging has an uneven structure and there is a lot of friction between the foam packaging and the packaging box. Therefore, this solution uses the push-pull fixed support component 4 to adjust the tightness of the fixed support component 4 on the wine bottle, ensuring that the wine bottle can be easily taken out.

[0042] See Figures 3-6 The top plate 2 includes a reinforcing plate 21, on which a protective sleeve 22 is installed. The protective sleeve 22 fits over the bottle neck. It should be noted that during the sealing process of the packaging box, the top plate 2 is flipped over. At this time, the protective sleeve 22 on the top plate 2 fits over the bottle neck, thus protecting the bottle neck. Simultaneously, the protective sleeve 22 prevents the bottle from shaking inside the packaging box. The purpose of the reinforcing plate 21 is to increase the compressive strength of the protective sleeve 22, thereby protecting the bottle neck.

[0043] See Figures 7-8 The top plate 2 also includes an upper pressure block 23, which presses down on the fixed pressing plate 44. It should be noted that during the sealing process of the packaging box, the top plate 2 is flipped over. At this time, the pressure block 23 on the top plate 2 presses down on the fixed pressing plate 44, fixing the fixed pressing plate 44 to the side wall 3. At this time, the fixed support component 4 is fixed inside the packaging box, preventing the fixed support component 4 and the wine bottle fixed on the fixed support component 4 from shaking inside the packaging box during transportation.

[0044] See Figure 6 Two wire holes 6 are respectively opened on the top plate 2 and the side plate wall 3. A ribbon is passed through the two wire holes 6 to fix the top plate 2 to the side plate wall 3.

[0045] It should be noted that when sealing the packaging box, the present invention uses a ribbon to pass through the thread hole 6 on the top plate 2 and the thread hole 6 on the side plate wall 3 in sequence, so that the top plate 2 is connected to the side plate wall 3 by the ribbon, ensuring that the packaging box in this solution can be easily unsealed and reused without damaging the packaging box.

[0046] See Figures 6-8 The plate slot box 5 includes an installation slot 52 with the opening of the installation slot 52 facing upward. A fixed pressing plate 44 is inserted into the installation slot 52. A hook groove 51 is provided on the installation slot 52. A tear strip 45 is provided on the fixed pressing plate 44 and is located in the hook groove 51. An anti-counterfeiting component 8 is installed on the top plate 2 and is snapped into the bottom of the tear strip 45.

[0047] Specifically, the anti-counterfeiting component 8 includes a hook 82. The top plate 2 is connected to the hook 82 via a connecting plate 81, and the hook 82 hooks onto the bottom of the tear strip 45.

[0048] It should be noted that, since this solution uses ribbons to connect the top plate 2 to the side wall 3, the packaging box will not be damaged during the disassembly process. Therefore, this solution cannot observe whether the packaging box has been opened, nor can it guarantee that the buyer has purchased wine that has not been switched.

[0049] Based on the above problems, the present invention provides a tear strip 45 on the fixed pressing plate 44. After the fixed pressing plate 44 is inserted into the mounting groove 52, the state of the tear strip 45 can be observed through the hook groove 51. During the packaging box sealing process, the top plate 2 is flipped over, and the pressing block 23 presses the fixed pressing plate 44, so that the pressing block 23 limits the fixed pressing plate 44, which can ensure that the hook 82 can more easily hook the tear strip 45. As the top plate 2 continues to flip over, the hook 82 hooks the bottom of the tear strip 45. Finally, the top plate 2 is connected to the side plate wall 3 by a ribbon. If the packaging box is opened, the top plate 2 will flip and cause the hook 82 to tear the tear strip 45. Therefore, before opening the package, the buyer can judge whether the packaging box has been opened by observing whether the tear strip 45 has been torn. If the tear strip 45 on the packaging box has been torn before purchase, it proves that the packaging box can be opened by human intervention. Therefore, the buyer should pay attention when purchasing. Conversely, if the tear strip 45 on the packaging box has not been torn before purchase, it proves that the packaging box has not been opened by human intervention. Therefore, the buyer can purchase with confidence.

[0050] Please see Figures 1-6 As shown, the present invention provides a folding method for a wine bottle packaging box. The method is applied to the wine bottle packaging box described in the above embodiments, and includes the following steps:

[0051] Step S1: Fold several support plates 41 together, then fold the bottom plate 1 so that the bottom plate 1 is perpendicular to the side wall 3.

[0052] Step S2: Fold the side panel wall 3 so that the side panel wall 3 wraps around the bottom plate 1. Then, place the wine bottle through the placement groove 42 onto the bottom plate 1. Then, pull up the fixing support component 4. Several support plates 41 gradually unfold, so that the several support plates 41 gradually form a corrugated plate structure. At this time, the two ends of the placement groove 42 gradually tilt and engage with the bottle wall. Then, insert the fixing pressing plate 44 at the tail end of the fixing support component 4 into the plate groove box 5. Then, fix the side panel wall 3 onto the bottom plate 1.

[0053] Step S3: Flip the top plate 2, and the pressure block 23 on the top plate 2 presses down on the fixed pressing plate 44. At this time, the fixed support assembly 4 and the wine bottle on it are fixed inside the packaging box.

[0054] like Figures 6-8 As shown, in a preferred embodiment of the present invention, step S2 specifically includes the following steps:

[0055] Step S21: Insert the fixing pressing plate 44 into the mounting groove 52 so that the tear strip 45 on the fixing pressing plate 44 is located in the hook groove 51. Then flip the top plate 2. As the top plate 2 rotates, the hook 82 on the top plate 2 hooks the bottom of the tear strip 45.

[0056] The implementation principle of this invention is as follows:

[0057] When folding, this invention requires first folding several support plates 41, such as... Figures 1-2 Next, fold the bottom plate 1 so that it is perpendicular to the side wall 3, as shown. Figures 2-3 Then fold the side panel 3 so that it covers the bottom plate 1. Next, place the wine bottle through the placement groove 42 onto the bottom plate 1. Then pull up the fixed support assembly 4, and several support plates 41 gradually unfold, as shown. Figure 3 As shown, several support plates 41 are gradually made into a corrugated structure. At this time, the two ends of the placement groove 42 are gradually tilted and engaged with the bottle wall. The fixing pressing plate 44 at the tail end of the fixing support component 4 is inserted into the installation groove 52. At this time, the state of the tear strip 45 can be observed through the hook groove 51. Then, the top plate 2 is flipped. At this time, the protective sleeve 22 on the top plate 2 is fitted onto the bottle mouth, thereby protecting the bottle mouth. Then, the pressing block 23 on the top plate 2 presses the fixing pressing plate 44. At this time, the fixing support component 4 can fix the bottle in the packaging box, preventing the bottle from shaking in the packaging box during transportation and ensuring the stability of the bottle. As the top plate 2 continues to flip, the hook 82 hooks the bottom of the tear strip 45. Finally, the top plate 2 is connected to the side plate wall 3 by the ribbon.

[0058] Before opening the packaging box, you need to check whether the tear strip 45 has been torn. If the tear strip 45 on the packaging box has been torn before purchase, it proves that the packaging box can be opened by human intervention, so buyers should pay attention when purchasing. Conversely, if the tear strip 45 on the packaging box has not been torn before purchase, it proves that the packaging box has not been opened by human intervention.

[0059] When it is necessary to unpack the box and remove the bottle, open the top panel 2, remove the fixing pressing plate 44 from the slot box 5, and then press down the fixing support assembly 4 to fold the support plates 41 together. When the two ends of the placement slot 42 on the support plate 41 are no longer in contact with the side wall of the bottle, the bottle can be taken out directly. The gap between the extension plate 43 and the side panel wall 3 provides folding space for the support plates 41. When it is necessary to put the bottle back into the box for storage, simply place the bottle through the placement slot 42 onto the bottom plate 1, then pull up the fixing support assembly 4 to make the placement slot 42 lock the bottle wall. Then insert the fixing pressing plate 44 into the slot box 5 to fix the bottle in place in the box for storage.

[0060] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
