Therefore, the present invention was conceived in consideration of the above points, and recycled, such as to eliminate the hassle of separating the handle and the packaging box by making the handle used to lift the packaging box out of paper material. Effective from the side, it can prevent environmental pollution caused by the exclusion of the use of synthetic resin materials, simplify the process required to complete a paper handle product from a single sheet of paper, and reduce the waste of scrap. It is excellent in terms of manufacturability and economy, such as being able to reduce the overall size of the product, and in particular, it contains glass bottle products that weigh a lot by securing the support stiffness of the handle by adopting a folding connection connecting the handle side and the disc side. It is an object of the present invention to provide a paper handle and a manufacturing method for a packaging box that can be usefully used as a handle for an existing packaging box.

In order to achieve the above object, the method of manufacturing a paper handle for a packaging box provided by the present invention has the following characteristics.

The method for manufacturing the paper handle of the packaging box includes a first step of preparing a single paper disc having a reinforcing plate foldable by a reinforcing plate fold line at one end, and a fold line parallel to the length direction in the middle of the width of the paper disc. And a handle with a pull-out hole is formed through the first disc of one of the first discs partitioned by the fold line, and a handle having a catching piece at both ends of the second disc of the other is cut off using a cut line, and both sides of the catching piece And the second disk region are connected to each other by a folding connection formed parallel to each other in the lengthwise direction of the handle, and the folding connection part is folded from each side of each side to each other from the side by side to both ends of the width of the second disk, forming two rows. The second step of overlapping the second disc side by folding of the line, and after applying the adhesive on the inner side of the second disc or the first disc, the first disc and the second disc are double-folded inward using a fold line. A third step of folding and bonding; a fourth step of folding and bonding the reinforcing plate toward the outer side of the second disk using a reinforcing plate fold line after applying the adhesive to the inner surface of the reinforcing plate; and And a fifth step of attaching the first and second disks folded in three layers together with the reinforcing plate to the box upper plate of the packaging box after applying the adhesive to the outer surface.

Therefore, in the method of manufacturing the paper handle of the packaging box, when the handle is pulled upward when in use, the handle is pulled upward, and the folding connector on both sides is in a folded state, connecting the handle and the second disc, and simultaneously pulling the locking pieces on both sides. The user can hold the handle and lift the packaging box while being moved while being caught by the folded connector, and the user can hold the handle and lift the packaging box. There are features that can be used suitably for outgoing packaging boxes.

Particularly, in the second step, when forming a handle having a locking piece using a cut line, a cut line is formed by leaving a predetermined length of both ends in the length direction on the second disk, thereby forming a cut line around the end of the cut line. It may include a process of allowing the entire area of both ends of the non-existent second disk in the longitudinal direction to be formed as a locking piece as it is.

Here, the reinforcing plate is integrally formed in the shape of a square plate having a relatively small area compared to the paper original plate on one of the long sides of both sides of the paper original plate. It is cut and molded together, and the reinforcing plate may be integrally connected to the original paper plate by a folding line of the reinforcing plate forming a boundary with the original paper plate.

In a preferred embodiment, in the second step, when the handle is cut and formed using a cut line on the second disc, a reinforcing band is separated from the handle side and the folded connector side while being connected to the second disc side between the handle and the folded connector. The process of forming together, when forming the handle withdrawal hole through the first disk, the process of forming the finger-hanging holes through both sides of the handle withdrawal hole, and the process of forming the handle through cuts using a cut in the second disk. The process of forming through the finger hook holes in contact with one side of the cut line on both sides to be molded, and when the handle is cut into the second disk, a plurality of break lines that are parallel to the handle along the width direction and arranged at regular intervals along the length direction are formed. The forming process may include a process of forming a pair of bent pieces in which three sides are cut and one side is attached using a cut line on the reinforcing plate.

In addition, the present invention may include a paper handle of a packaging box manufactured by a method of manufacturing a paper handle of a packaging box including the first to fifth steps according to another embodiment above.

The paper handle and manufacturing method of the packaging box provided by the present invention has the following effects.

First, by connecting the handle side and the disc side of the paper handle to the folding connection part, and strengthening the support stiffness of the handle by using the support and locking force exerted by the folding connection part, it contains glass bottle products that weigh a lot. Even when used as a handle for a packaging box, there is an effect that paper handles can be widely applied to various types of packaging boxes, such as being able to completely eliminate the problem of the handle breaking or falling off.

Second, the handle used for the packaging box is made of paper, which is the same material as the packaging box, and the optimal cross-sectional structure is provided to the handle of the paper material to secure its own strength. It has the effect of improving the efficiency in terms of recycling, such as eliminating the hassle and inconvenience of separating the material separately, and also has the effect of actively preventing environmental pollution due to the exclusion of the use of the handle made of the conventional synthetic resin material. .

Third, it is possible to simplify the overall manufacturing process required to complete the paper handle product from a single sheet of paper, and the end of the original paper plate is used as a locking piece without separately forming the shape of the locking piece of the handle. It is possible to reduce the waste of scrap, such as reducing the molding process, while reducing the overall size of the paper handle, reducing the waste of scrap, and simplifying the structure of the manufacturing mold. It is possible to improve the assembling property, and thus, there is an effect of improving the manufacturability and economy related to the manufacture of the paper handle.

Fourth, by reinforcing the bottom side of the handle with a reinforcing plate, the overall strength of the paper handle can be improved, as well as the ability to completely eliminate the problem of the handle being separated, thereby enhancing the functionality of the handle. There is an effect of improving the convenience related to the use of the handle, such as the provision of a folding piece that can create a space for entering, so that the handle can be held more easily.

Fifth, when the handle is formed using a cut line, the locking piece function is performed using both ends of the original plate without forming a separate locking piece, thereby simplifying the manufacturing process and assembly process, as well as reducing unnecessary scrap. In addition, when manufacturing and assembling using an automated process, it is possible to secure linkage between processes, such as being able to exclude interference due to excess scrap adjacent to the jammed piece as before, and thus, the automated process for the production of paper handles and In connection there is an effect that can improve the manufacturability and productivity.

7 and 8 are perspective views showing a paper handle according to an embodiment of the present invention
9 is a perspective view showing a state of use of a paper handle according to an embodiment of the present invention

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 to 6 are perspective views showing a method of manufacturing a paper handle according to an embodiment of the present invention.

As shown in Figs. 1 to 6, the method of manufacturing the paper handle of the packaging box is to produce a paper handle product using a single original paper plate having a predetermined thickness, and a paper handle product with a minimum process and a simple process. As a method of manufacturing, it is possible to improve productivity and improve economic efficiency through process simplification and manufacturing cost reduction. In particular, the support stiffness of the handle is strengthened to make it useful as a handle for a packaging box that weighs a lot. There is this.

First, as a first step, a first step of preparing a single original sheet of paper 10 is performed.

The paper original plate 10 is a paper material that can be formed in various shapes such as square, rectangle, oval, circle, polygon, etc. In the present invention, a paper original plate 10 in a rectangular shape is applied.

This paper disc 10 is better if the thickness is thicker for solidity, but it can be made in a thickness of about 0.1 to 1.5 mm because economical aspects or formability aspects must be considered, and from a practical point of view, a thickness of about 0.4 to 0.6 mm It is preferable to apply the original paper plate 10 made of.

At this time, at one end of the original paper 10, for example, a reinforcing plate 28 in the shape of a square plate having a relatively small area compared to the original paper 10 is at one of the long sides of both sides. The reinforcing plate 28 is integrally formed, and the reinforcing plate 28 can take a form integrally connected to the paper original plate 10 by a reinforcing plate folding line 29 that forms a boundary with the paper original plate 10.

For example, when cutting the paper original plate 10 by a press or the like, the reinforcing plate 28 can also be cut and molded.

Next, as a second step, a step of forming a handle withdrawal hole 13, a handle 17, and the like in the paper original plate 10 is performed.

To this end, fold lines 11 parallel along the length direction are formed in the middle of the width of the original paper plate 10.

That is, at the point where the width W of the rectangular paper disk 10 is divided by 1/2, a straight fold line 11 parallel to the length L direction of the paper disk 10 is formed.

Here, the fold line 11 may be formed by a press process in a press facility.

In this case, the fold line 11 can serve as a reference line when the paper original plate 10 is folded in two layers in a third step to be described later.

By forming the fold line 11 in the middle of the width of the paper original plate 10, the paper original plate 10 is divided into two regions, namely, a first disk 12 on one side and a second disk 14 on the other side. .

In addition, a handle take-out hole 13 is formed through the first disk 12 on one side partitioned by the fold line 11.

Here, the handle take-out hole 13 may be formed in the shape of a rectangular hole formed parallel to the length direction of the first disk 12 in the central region of the first disk 12.

The width of the handle take-out hole 13 may be the same as or slightly larger than the width of the handle 17, and the length of the handle take-out hole 13 is relatively shorter than the length of the handle 17. I can.

In this case, the second step may further include forming a finger hook hole 23a for holding the handle 17 when the handle take-out hole 13 is formed through the first disk 12.

For example, when the handle take-out hole 13 in the form of a rectangular hole is formed in the central region of the first disk 12, the handle take-out hole 13 is located at the middle of the length of the handle take-out hole 13 on both sides thereof. The finger hook hole 23a having a substantially trapezoidal shape that communicates as it is is formed through together.

The finger-hanging hole (23a) formed in this way provides a space for the finger to enter when the user holds the handle (17). Accordingly, the user inserts a finger through the finger-hanging hole (23a) and then the handle (17). ), you can easily grab both sides of the width.

Here, the handle take-out hole 13 and the finger hook hole 23a may be formed by a punching process in a press facility.

In addition, a handle 17 having a locking piece 16 is formed on the other second disk 14 partitioned by the fold line 11.

The handle 17 is a long rectangular paper strip, made by using a part of the original paper plate 10 as it is, and has a shape corresponding to the outer shape of the handle 17 while operating vertically (not shown). It is possible to form the handle 17 using the cut line 15 formed by the operation of.

That is, the outer shape of the handle 17, for example, is made along the outer shape of the handle part in the shape of a long strip of a certain width excluding the locking pieces 16 at both ends, and at regular intervals parallel along the length direction of the handle. The handle 17 is separated from the side of the second disc 14 by excluding a part of the handle 17 by the two parallel cut lines 15 so that it can be distinguished.

At this time, the formation position of the handle 17 is the formation position of the handle take-out hole 13 formed in the first disk 12 when the first disk 12 and the second disk 14 are folded in two layers. Can be matched.

In addition, locking pieces 16 are integrally formed at both ends of the handle 17 in the longitudinal direction, and the locking pieces 16 at this time are also made by using a portion of the original paper plate 10 as it is.

For example, when forming the handle 17 having the locking piece 16 using the cut line 15, the cut line 15 is formed by leaving both ends of the second disk 14 in the longitudinal direction for a predetermined length. By doing so, the entire area of both ends in the longitudinal direction of the second disk on which the cut line 15 is not formed with the end of the cut line 15 as a boundary can be formed into the locking piece 16 as it is.

Here, the width of the locking piece 16 is made to be a relatively large width compared to the width of the handle 17, and accordingly, when the handle 17 is withdrawn, the handle 17 passes through the handle withdrawal hole 13 When exiting, the locking piece 16 can be caught without being able to follow along.

In particular, in the second step, when cutting the handle 17 using the cut line 15, in order to prevent complete separation of the handle 17, there are a total of 4 pieces each for connection with the second disc 14 side. To form a belt-shaped folding connection (18).

For example, the engaging piece 16 and the handle 17 of the integral type are cut-out while leaving the folding connecting portion 18 formed parallel to the handle lengthwise between both sides of the locking piece 16 and the second disk area. do.

In other words, the cut line 15 for forming the integral locking piece 16 and the handle 17 does not continue to be connected, and the cut line 15 is cut off at the portion where the folding connector 18 is connected to the second disc side. The locking piece 16 and the handle 17 are cut and formed.

In this way, the locking piece 16 and the handle 17 are not completely separated from the second disc 14 side, but are connected to the second disc 14 side by using the folding connection part 18, so that a subsequent process (for example, When performing the process of applying the adhesive, the process of folding it in two layers, the process of attaching it to the packaging box, etc.), the second disc (without any change in position such as the handle 17 is removed or the position is distorted to the side). 14) It is possible to stick to the position of the top, and in the end, it is possible to obtain advantages such as allowing the subsequent process to be performed accurately and smoothly.

In addition, when forming the handle 17 using the cut line 15, the cut line 15 is provided on the second disk 14 so that the both ends of the second disk 14 are used without forming a separate locking piece. By making the locking piece 16, it is possible to simplify the manufacturing process and assembly process, as well as reduce the occurrence of unnecessary scrap, and at the same time, when manufacturing and assembling using an automated process, excess scrap adjacent to the locking piece (second It is possible to exclude interference due to original scrap).

In particular, the folding connection part 18 is a folding connection part folding line 31a, which is formed at a boundary part between the second disk 14 side and a boundary part with the locking piece 16 side when the handle 17 is withdrawn. 31b)) while being positioned between the second disc 14 and the locking piece 16 and overlapping, and exerting a supporting force in this folded state, attaching the handle 17 side to the second disc 14 side By doing so, the handle 17 is able to exhibit more reinforced support stiffness, and in the end, the handle 17 is firmly supported by the second disc 14 through the folding connection 18 and the load caused by the packaged product. Even in the case of this action, it is possible to maintain solid support stiffness.

This folding connector 18 can also be formed together when forming the handle 17 and the locking piece 16 with the cut line 15.

In addition, in the second step, when the handle 17 is cut and formed by using the cut line 15 on the second disk 14 and at the same time, the locking piece 16 and the folded connector 18 are made naturally, the handle Arranged side by side between (17) and the folding connection (18), one side is connected to the second disk (14) side, while the other side is separated from the locking piece (16) side and the handle (17) side and the folding connection ( 18) It includes a process of forming the side and the separated reinforcement strip (19) together.

Unlike the folding connector 18 that is folded by the pulling of the handle 17, the reinforcing strip 19 maintains the unfolded state when the handle 17 is pulled and at the same time on the bottom surface of the first disc 12 While being closely supported, the holding force is exerted, and as a result, even when the locking piece 16 is pulled upward by the load acting on the handle 17, it is possible to effectively prevent the locking piece 16 from being detached and falling out.

Further, in the second step, when the handle 17 is cut by using the cut line 15 on the second disk 14, the finger hook hole 23b in contact with one side of the cut line on both sides of the handle 17 is formed. The process of forming through together is carried out.

For example, when making a cut 15 for forming the handle 17 in the central region of the second disc 12, the handle 17 is formed on both sides of the handle 17 at an intermediate length of the handle 17 A substantially trapezoidal finger-hanging hole 23b in contact with the region is formed through together.

Here, when the first disk 12 and the second disk 14 are folded in two folds based on the fold line 11, the finger hook hole 23b formed in the second disk 14 is the first disk ( The finger hook holes 23a formed in 12) can be matched to each other at the same position.

The finger-hanging hole (23b) formed in this way provides a space for the finger to enter when the user holds the handle (17), and accordingly, the user inserts a finger through the finger-hanging hole (23b) and then the handle (17). ), you can easily grab both sides of the width.

In addition, in the second step, when the handle 17 is cut and formed on the second disk 14, a plurality of break lines are parallel to the handle 17 along the width direction of the handle and are arranged at regular intervals along the length direction of the handle ( 24) can be carried out.

In this way, a plurality of break lines 24 are formed on the handle 17 at regular intervals, so that the handle 17 drawn outward is naturally bent in an arc shape or an arch shape by the break line 24. Therefore, when the user grips the handle 17, it is possible to comfortably hold the handle 17 without any discomfort.

In this way, the locking piece 16 and the handle 17 on the second disk 14, the folding connector 18, the reinforcing strip 19, the finger hook hole 23b, and the break line 24 are formed by pressing Through the cutting process, punching process, press process, etc. in the facility, it can be formed at the same time by one press operation, and at the same time, the handle take-out hole 13 on the first disk 12 and the finger hook hole 23a The molding of can also be simultaneously molded by a punching process in a press facility.

That is, the folding line 11 formed on the first disk 12 and the second disk 14, as well as the locking piece 16 and the handle 17, the folding connection part 18, and the folding connection part folding line 25a ,25b), reinforcement strip 19, finger hook holes 23a, 23b, break line 24, and handle take-out hole 13 can be simultaneously molded by one press process of the press facility, The number can be drastically reduced, and since scrap can be removed by using the original plate material as a handle, etc., manufacturing efficiency and economy can be improved, such as making it easier to manufacture and lowering costs.

In addition, in the second step, a process of forming a pair of bent pieces 30 in which three sides are cut and one side is attached using a cut line on the reinforcing plate 28 may be performed.

For example, through one press operation using a cut line cutting process in a press facility, it is possible to form a bent piece 30 in the form of which three sides are completely cut and one side is attached to the side of the reinforcing plate 28. do.

When the both sides of the handle 17 are pressed with a finger in order to hold the handle 17, the bent piece 30 is bent inside (in the box), and eventually the bent piece 30 is formed while being bent inward. Since the fingers can be inserted deeply to both sides of the handle 17 using the space, the handle 17 can be easily gripped.

Of course, even in the case of the bent piece 30, the locking piece 16 and the handle 17 on the second disc 14, the fold connection part 18 and the fold connection part fold lines 25a, 25b, and the reinforcing band 19 , When forming the finger hook hole 23b, the break line 24, it can be simultaneously formed by one press operation through a cut line cutting process, a punching process, a press process, etc. in a press facility. The handle take-out hole 13 and the finger hook hole 23a on the disk 12 may be formed at the same time by a punching process in a press facility.

Next, as a third step, a step of folding the first disc 12 and the second disc 14 in two layers is performed.

For example, an adhesive 20 is applied to the inner side of the second disc 14 or the first disc 12, preferably the inner side of the second disc 14, and then the fold line 11 The first and second discs 12 and 14 are folded in two layers and adhered to each other inwardly facing each other by using.

At this time, the adhesive 20 may be a known hot melt adhesive or the like, and may be applied over an appropriate area to an inner blank area (an area where a handle or the like is not formed) of the second original plate 14.

Next, as a fourth step, after applying the adhesive to the inner side of the reinforcing plate 28, folding the reinforcing plate 28 toward the outer side of the second disc 14 using the reinforcing plate fold line 29 Perform the bonding step.

That is, in a state in which the first and second disks 12 and 14 are folded in two layers, the reinforcing plate 28 is bent downward of the second disk 14 and then the second disk 14 is covered. By folding and bonding, a paper handle made of three layers of the first disk 12, the second disk 14, and the reinforcing plate 28 is made.

At this time, the length of the reinforcing plate 28 may be substantially similar to the length of the handle 17 excluding the locking pieces 16 at both ends, and accordingly, when the handle 17 is pulled for use, the handle ( Since the locking piece 16 of 17) is also hung at the longitudinal end of the reinforcing plate 28, it is possible to secure a firm locking state of the locking piece 16, and eventually the handle 17 is pulled outward. It is possible to completely eliminate the problem of deviation.

In addition to the role of the reinforcing plate 28 holding the locking piece 16 of the handle 17, the reinforcing plate 28 serves to reinforce the overall strength of the paper handle by being stacked in three layers together with the first and second discs 12 and 14. You can also do it.

Next, as a fifth step, a step of attaching the first disc 12 and the second disc 14 folded in three layers together with the reinforcing plate 28 to the box top plate 22 of the packaging box 21 is carried out. .

To this end, after applying an adhesive 20 such as a hot melt on the outer surface of the first disk 12 of the first disk 12 and the second disk 14 and the reinforcing plate 28 folded in three layers, As shown in FIG. 2, the outer surface of the first disk 12, that is, the upper surface of the first disk 12 to which the adhesive 20 is applied, is placed on the back surface of the box top plate 22 of the packaging box 21 ( On the inner side).

When the three layers of the first disk 12, the second disk 14, and the reinforcing plate 28 are attached to the rear surface of the box top plate 22 of the packaging box 21, the hole of the box top plate 22 is closed. Through this, the handle 17 can be exposed upward.

Here, by applying a method of attaching the three layers of the first disk 12, the second disk 14, and the reinforcing plate 28 to the back surface of the box top plate 22 of the packaging box 21, It is very efficient in linking the process of attaching the paper handle to the manufacturing process of the packaging box.

In other words, the packaging box manufacturing process and the paper handle attachment process can be implemented as a series of linked automated processes.

7 and 8 are perspective views showing a paper handle according to an embodiment of the present invention.

As shown in Figs. 7 and 8, the paper handle may be made of a type without a reinforcing strip and a type with a reinforcing strip.

As an example, the paper handle is made of a three-ply stacked structure of one first disc 12, a second disc 14, and a reinforcing plate 28, and the upper side of the first disc 12 is a handle 17 is exposed, and the locking pieces 16 formed on both sides of the handle 17 come into contact with the second disc 14 side at the bottom of the first disc 12.

In addition, both locking pieces 16 of the handle 17 are attached to the first disk 12 side by four fold connection portions 18.

When the handle 17 is pulled upward in this state, the locking pieces 16 on both sides are also pulled, and the folding connection 18 at this time is folded by the folding connection line 25a, 25b, and the first disk 12 ) And the locking piece (16), and the locking piece (16), which has been interfered with by the folding connector (18) that is folded in this way, is not pulled anymore and is fixed, so that the handle (17) is It is possible to perform the role of a handle while maintaining the pulled up state by the locking structure of (16).

As another example, the paper handle is made of a three-ply stacked structure of the first disc 12, the second disc 14, and the reinforcing plate 28, and the upper side of the first disc 12 is a handle ( 17) is exposed, and the locking pieces 16 formed on both sides of the handle 17 are in contact with the second disk 14 side at the bottom of the first disk 12 on the same line.

In addition, both locking pieces 16 of the handle 17 are attached to the first disk 12 side by four folding connecting portions 18, and between the folding connecting portions 18 and the locking pieces 16 In the second disc 14 side reinforcing bands 19 connected to one side are arranged side by side.

When the handle 17 is pulled upward in this state, the locking pieces 16 on both sides are also pulled, and the folding connection 18 at this time is folded by the folding connection line 25a, 25b, and the first disk 12 ) And the locking piece (16), and the locking piece (16), which has been interfered with by the folding connector (18) that is folded in this way, is not pulled anymore and is fixed, so that the handle (17) is It is possible to perform the role of a handle while maintaining the pulled up state by the locking structure of (16).

At this time, between the folded connection part 18 and the locking piece 16, the reinforcing strip 19 is in a straightened state and is in close contact with the bottom surface of the first disc 12 to exert a supporting force, and accordingly, the locking piece 16 ) And the upward pulling force acting on the fold connection part 18 can be offset to some extent by the support force exerted by the reinforcing strip 19, so that the locking piece 16 and the fold connection part 18 While being prevented from falling out, the handle 17 is able to maintain a more rigid fixed state.

9 is a perspective view showing a state of use of a paper handle according to an embodiment of the present invention.

As shown in Fig. 9, when the first disk 12 and the second disk 14 and the reinforcing plate 28 are attached to the box top plate 22 of the packaging box 21 in three layers, the first The handle 17 is exposed through the handle withdrawal hole 13 of the disk 12.

In this state, when the box cover 26 of the packaging box 21 is closed, the handle 17 is exposed and visible through a hole portion in the box top plate 22 and a hole portion in the box cover 26, Subsequently, the box locking piece 27 is fastened to the box cover 26 to completely close the packaging box 21.

On the other hand, when the user pulls the handle 17 to lift the packaging box 21, the folding connector 18 connecting the handle 17 and the locking piece 16 side and the disc side is bent and folded. At the same time, the locking pieces 16 of both sides slide inward toward the pull of the handle.

When the locking piece 16 that was moving in this way is no longer pulled by the folded connector 18, the handle 17 is no longer withdrawn, and the handle 17 at this time is a gentle arc. It forms a (弧) shape and is withdrawn to an appropriate length, and the user can conveniently carry the packing box 21 by holding the handle 17 protruding upward.

At this time, even when a load is applied to the handle 17, the locking piece 16 of the handle 17 is able to maintain a solid fixed state by the support force exerted by the folding connection part 18 and the reinforcing strip 19. In the end, since the handle 17 is also stably supported, it is possible to safely carry the packaging box 21 even when the packaging box 21 weighs a lot.

As described above, in the present invention, the handle used in the packaging box is made of a paper material, and a new manufacturing method is provided in which a paper handle product is completed with only a minimum number of processes (cutting, bending, bonding, etc.) along with using one original paper As a result, there is no need to separate the handle during separate discharge, so it is easy to process, and the handle of synthetic resins as in the past can be eliminated to prevent environmental pollution, and one original paper sheet can be folded or cut out at once. Since it can be manufactured only by the process of ``, it has excellent advantages in terms of manufacturing efficiency as well as economic efficiency.

In particular, in the present invention, by adopting a folding connection connecting the handle side and the disc side to secure the support stiffness of the handle, it can be usefully used as a handle of various types of packaging boxes containing glass bottle products that weigh a lot, In addition, when the handle is formed using a cut line, it is possible to simplify the manufacturing process and assembly process as well as reduce the occurrence of unnecessary scrap by using the both ends of the original plate to perform the locking piece function without forming a separate locking piece. When manufacturing and assembling using an automated process, it is possible to improve the productivity and productivity related to the automated process, such as securing linkage between processes, such as being able to exclude interference due to excess scrap adjacent to the jammed piece as before. have.
