Paper handle for packaging box {PAPER GRIP FOR PACKING BOX}

The present invention relates to a handle made of paper applied to boxes packaging beverage products, stick products, etc., and in particular, the handle is provided with reinforcing paper such as Korean paper to keep the contents of the packaging box. This is about a paper handle for a packaging box that can prevent the handle from breaking or falling off even when it is heavy.

In general, packaging boxes serve to prevent the products contained inside from being damaged during distribution and to facilitate distribution by packaging them in larger units.

Usually, packaging boxes are made using paper plates that are light and have a strong structure, and have a structure that allows opening on the top and bottom. After sealing the bottom, the product is loaded inside and the top is sealed to facilitate distribution. do.

Recently, paper board packaging boxes that can pack a large amount of individually packaged products, such as snack packaging boxes, powder pack packaging boxes, and stick coffee mix packaging boxes, have been mainly distributed. These packaging boxes have a cut on the front. It is equipped with a product outlet in the form of a dotted line and a handle made of synthetic resin on the top.

Most existing handles consist of a grip part that the user can hold with their hands and a base part that is joined to the side of the box to support the grip part, and the grip part is inserted into the catching hole of the base part using the locking pieces at both ends. assembled into a structure.

However, because these handles are made of synthetic resin, there is the inconvenience and inconvenience of having to remove the handle from the paper packaging box when discharging separately. Because of this inconvenience, most consumers leave the handle attached. There is a problem in that packaging boxes are thrown away as is, which not only wastes resources due to difficulties in recycling but also causes environmental pollution.

In recent packaging boxes, there is a trend to replace paper handles made of synthetic resin materials with handles made of paper materials. However, handles made of existing paper materials are not only expensive and complicated to manufacture, but also waste a lot of scrap, making them less economical as well. There are disadvantages in terms of manufacturability, and in particular, due to its weak strength, it is difficult to apply it to boxes for packaging heavy items, such as easily tearing or falling apart when the contents of the packaging box are heavy.

Therefore, the present invention was developed with this in mind, and the handle used to lift the packaging box is made of paper material, thereby eliminating the inconvenience of separating the handle and packaging box when discharging them, thereby enabling recycling. At the same time, it is effective in terms of preventing environmental pollution due to the exclusion of synthetic resin materials, simplifying the process required to complete a paper handle product from a single sheet of paper, and reducing waste of scrap. The overall size of the handle can be reduced, thereby improving manufacturability and economic efficiency. Above all, reinforcing paper made of Korean paper, etc. is provided on the back side of the paper disk on which the handle is formed. The purpose is to provide a paper handle for packaging boxes that can be usefully used as a handle for packaging boxes containing heavy glass bottle products, etc., by increasing the strength of the paper.

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

The paper handle for the packaging box is a first disk that is folded at both ends in the longitudinal direction by the first and second reinforcing band fold lines and has a reinforcing band attached to the bottom of the catching piece on the second disk. and a second disk having a handle formed with a folding connection part that is folded by the folding line of the folding connection unit at both ends in the longitudinal direction and a locking piece that hangs on the bottom of the first disk, and which are located on both sides in the width direction and at the same time, in the width direction. It has a pair of first-stage folded portions and a second-stage folded portion formed in a folded form, and includes reinforcing paper adhered to the rear surface of the second disk including the handle.

Accordingly, the paper handle for the packaging box has three layers with the first disk, the second disk, and the reinforcing paper overlapping side by side, and when the handle is pulled upward during use, the handle is pulled upward, and the folding joints on both sides are in a folded state. At the same time as connecting the handle and the second disk, the movement is restricted by the folding joint that moves and folds while the locking pieces on both sides are pulled, and in addition, the reinforcing band holds the locking piece of the handle, thereby maintaining the pull-out state of the handle and helping the user. The feature is that the packaging box can be lifted by holding the handle.

Here, a pair of first-stage folded portions and a second-stage folded portion located on one side of the width direction of the reinforcement paper and another pair of first-stage folded portions and a second-stage folded portion located on the other side of the width direction are symmetrical to each other based on the width direction. It can be formed in a form that continues side by side along the length direction, and in this case, the reinforcement paper can be made of a material such as Korean paper (Korean paper).

In addition, the reinforcing band is formed integrally at both ends in the longitudinal direction of the first disk by the first reinforcing band fold line and the second reinforcing band fold line, which are parallel and form two rows along the width direction of the reinforcing plate, and the connecting pieces between them. You can.

In addition, the handle having the locking piece is made by cutting lines formed by leaving a certain length on both ends in the longitudinal direction of the second disk, so that the entire area of both longitudinal ends of the second disk without cutting lines remains the same. The feature is that it can be molded into a locking piece.

In a preferred embodiment, the handle may be formed with a plurality of bending lines that are parallel along the width direction of the handle and disposed at regular intervals along the length direction, and the first disk is cut on three sides by a cutting line and one side is cut. A pair of attached folds may be formed.

The paper handle for packaging boxes provided by the present invention has the following effects.

First, the strength of the paper handle is increased by providing a bent reinforcing paper made of Korean paper, etc. on the handle side of the paper handle, so that the packaging box contains heavy glass bottle products, etc. Even when used as a handle, the problem of the handle breaking or falling off can be completely eliminated, which has the effect of allowing the paper handle to be widely applied to various types of packaging boxes.

Second, by applying a reinforcing part to the bottom of the handle side of the paper handle that holds the handle being pulled upward and exerts an appropriate supporting force, the durability of the paper handle can be improved, including preventing the handle from breaking or falling off even when the product is heavy. There is an effect.

Third, the handle used in the packaging box is made of paper, the same material as the packaging box, and the handle made of paper is given an optimal cross-sectional structure to ensure its own strength, so that the handle and the packaging box are separated when the packaging box is separated and discharged. It can increase efficiency in terms of recycling, such as eliminating the inconvenience and inconvenience of having to separate the handles separately, and also has the effect of actively preventing environmental pollution due to the exclusion of the use of handles made of conventional synthetic resin materials. .

Fourth, the overall manufacturing process required to complete a paper handle product from a single sheet of paper can be simplified, and the end of the paper disk can be used as a locking piece instead of separately molding the shape of the handle's locking piece. Reducing the waste of scrap by reducing the molding process, reducing the overall size of the paper handle, reducing the waste of scrap, simplifying the structure of the production mold, reducing the process and reducing production costs, and It is possible to improve assembly, and thus has the effect of improving manufacturability and economic efficiency related to the production of paper handles.

Fifth, by reinforcing the bottom of the handle with Korean paper (Korean traditional paper), there is an effect of improving the functionality of the handle, including improving the overall strength of the paper handle and completely eliminating the problem of the handle coming off. By providing a bending piece that can create a space for fingers to enter, there is an effect of improving the convenience associated with using the handle, such as making it easier to grip the handle.

Sixth, when forming a handle using a cut line, the locking piece function is performed by using both ends of the original plate as is rather than forming a separate locking piece, which not only simplifies the manufacturing process and assembly process, but also reduces the generation of unnecessary scrap. In addition, when manufacturing and assembling using an automated process, it is possible to secure connectivity between processes, such as eliminating interference due to excess scrap adjacent to the holding piece as before. Therefore, the automated process for manufacturing paper handles and In this regard, there is an effect of improving manufacturability and productivity.

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

1 to 5 are perspective views showing a method of manufacturing a paper handle according to an embodiment of the present invention.

As shown in Figures 1 to 5, the paper handle manufacturing method manufactures a paper handle product using a single sheet of paper with a predetermined thickness and reinforcing paper made of Korean paper, etc., and requires minimal processing and simple operation. As a method of manufacturing paper handle products through a process, it is possible to improve manufacturability and improve economic efficiency by simplifying the process and reducing production costs. In particular, by strengthening the support rigidity of the handle, it is possible to remove the heavy weight without problems such as tearing or falling out. It has features that make it useful as a handle for packaging boxes.

First, as a first step, a step of preparing one paper original plate 10 and one reinforcing paper original plate 21 is performed.

The paper original plate 10 is a paper material original plate that can be made of various shapes such as square, rectangular, oval, circular, and polygonal, and the reinforcing paper original plate 21 also has various shapes such as square, rectangular, oval, circular, and polygonal. As an original plate made of Korean paper that can be formed in a shape, the present invention uses a paper original plate 10 and a reinforcing paper original plate 21 in a rectangular shape.

The thicker the paper disk 10 is, the better for sturdiness, but since economic efficiency and formability must be considered, it can be made with a thickness of about 0.1 to 1.5 mm, and from a practical point of view, it can be made with a thickness of about 0.4 to 0.6 mm. It is desirable to apply a paper original plate 10 made of.

In addition, it is preferable to use Korean paper (Korean paper) as the reinforcing paper disk 21, which is tough, has a long lifespan, and is light and soft.

Here, it is preferable to use Korean paper having a weight of about 120g as the reinforcing paper disk 21.

In addition, in the first step, a process of making reinforcement paper 27 having a predetermined bent cross-section is performed by bending and molding the reinforcing paper disk 21.

For this purpose, a pair of first-stage folded portions 13 and second-stage folded portions 12, which are located on both sides of the reinforcing support disk 21 and are simultaneously folded in the width direction, are bent and formed to form an outer Create a reinforcing paper (27) having a first-stage folded portion (13) on the side and a second-stage folded portion (12) on the inside.

At this time, a pair of first-stage folded parts 13 and a second-stage folded part 12 located on one side of the reinforcement paper 27 in the width direction, and another pair of first-stage folded parts 13 located on the other side of the width direction of the reinforcing paper 27. And the two-stage folded portion 12 may be symmetrical to each other based on the width direction and continuously continuous in parallel along the longitudinal direction.

Here, the portion where the first-stage folded portion 13 is formed can form two layers with the reinforcing support disk 21, and the portion where the second-stage folded portion 12 is formed can be formed with the reinforcing disk 21 and the second-stage folded portion 12. Together, they can form three layers.

The reinforcing paper 27 made in this way is integrally adhered to one side of the paper disk 10, that is, the back side of the second disk 14, where the handle 17 is formed, with an adhesive.

In addition, the reinforcing paper 27 may have a size that can cover the entire back surface of the second disk 14, but since it is used for the purpose of substantially strengthening the handle portion, the handle 17 It is desirable to have an appropriate size that can cover to some extent.

Next, as a second step, a handle 17, a reinforcement band 19, etc. are formed on the paper original plate 10.

For this purpose, a fold line 11 is formed parallel to the longitudinal direction in the middle of the width of the paper original plate 10.

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

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

The fold line 11 at this time can serve as a reference line when folding the original paper plate 10 in two in the third step.

By forming the fold line 11 in the middle of the width of the paper original plate 10 in this way, the paper original plate 10 has two areas, that is, the first original plate 26 on one side and the reinforcement paper 27 on the other side are bonded. It is divided into a second disk (14).

In addition, a reinforcing band 19 is formed integrally with the first disk 26 on one side divided by the fold line 11.

For example, by cutting and forming reinforcement portions, that is, roughly “T” shaped reinforcement bands 19, on both longitudinal ends of the first disk 26 through press cutting, both ends of the first disk 26 The reinforcement band 19 can be formed as an integrated piece.

In addition, the second disk 14 on the other side divided by the fold line 11, that is, the reinforcing paper 27 is bonded to the second disk 14, which forms two layers, and has a handle having a locking piece 16. It forms (17).

The handle 17 is a rectangular long paper strip, which is made using a portion of the original paper plate 10, and has a shape corresponding to the outer shape of the handle 17 and a cutter (not shown) that moves up and down. The handle 17 can be formed using the cut line 15 formed by the operation of .

That is, it is made according to the outer shape of the handle 17, for example, the outer shape of the handle portion in the shape of a long strip of a certain width excluding the locking pieces 16 at both ends, and has a regular interval parallel along the length of the handle. The handle 17 can be separated and distinguished from the second disk 14 by the two parallel cutting lines 15, except for a portion.

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

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

Here, the width of the locking piece 16 is relatively large compared to the width of the handle 17, and accordingly, when the handle 17 is pulled out, the handle 17 is attached to the handle in the packaging box 100. When exiting through the draw-out hole 101, the catching piece 16 cannot go out together and may become stuck.

In particular, in the second stage, in order to prevent complete separation of the handle 17 when cutting and forming the handle 17 using the cut line 15, there are a total of 4 pieces, 2 on each side, for connection to the second disk 14. A band-shaped folded connection portion 18 is formed.

For example, the integrated locking piece 16 and the handle 17 are cut away, leaving a folded connection portion 18 formed parallel to the length of the handle between both sides of the locking piece 16 and the second disk area. do.

That is, the cut line 15 to form the integrated locking piece 16 and the handle 17 does not continue, but the cut line 15 is cut at the area where the folding connection part 18 connects to the second disk side, thereby forming an integrated form. 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 disk 14 side, but are connected to the second disk 14 side using the folding connection portion 18, so that in the subsequent process (e.g., When performing the adhesive application process, double folding process, attaching process to the packaging box side, etc.), the second disk (17) is attached without changing its position, such as the handle 17 falling off or being crooked to the side. 14) It is possible to maintain the position of the bed, which ultimately provides benefits such as enabling subsequent processes to be carried out accurately and smoothly.

In addition, when forming the handle 17 using the cut line 15, both ends of the second disk 14 are used as is without cutting a cut line 15 in the second disk 14 and forming a separate locking piece. By creating the holding piece 16, it is possible to simplify the manufacturing process and assembly process, as well as reduce the generation of unnecessary scrap, and at the same time, when manufacturing and assembling using an automated process, excess scrap adjacent to the holding piece (the second part) is removed as before. Interference caused by (original scrap) can be excluded.

In addition, the folding connection portion 18 is a folding connection fold line 25a formed at the boundary portion with the second disk 14 side and the boundary portion with the locking piece 16 side when the handle 17 is pulled out. As it is folded by 25b)), it is located between the second disk 14 and the locking piece 16 and overlaps, and in this folded state, it exerts a supporting force and attaches the handle 17 side to the second disk 14. By doing so, the handle 17 can demonstrate further enhanced support rigidity, and as a result, the handle 17 is firmly supported on the second disk 14 via the folding connection portion 18, thereby supporting the load caused by the packaging product. Even in this case, solid support rigidity can be maintained.

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

In addition, in the second step, in order to fold the reinforcing band 19 integrally formed at both ends of the first disk 26, a certain distance is formed at the boundary between the reinforcing band 19 and the first disk 26. While maintaining the two rows of fold lines parallel to the width direction of the reinforcing band, that is, forming a first reinforcing band fold line (19a) and a second reinforcing band fold line (19b), these first reinforcing band fold lines (19a) and the second reinforcing band fold line (19a) are formed. 2. It includes the process of forming a connection band (20) made between the reinforcement band fold lines (19b).

Accordingly, when the locking piece 16 is pulled by pulling the handle 17 and the folding connection portion 18 is folded, the reinforcing band 19 attached to the locking piece 16 is also pulled. At this time, The first reinforcing band fold line (19a) and the second reinforcing band fold line (19b) are also folded together, and the portion between the first reinforcing band fold line (19a) and the second reinforcing band fold line (19b), that is, the connection band ( 20) is erected vertically and exerts a supporting force at the same time, and eventually the locking piece 16 is held on the side of the first disk 26 together with the reinforcing band 19, acting on the handle 17. Even when the locking piece 16 is pulled upward by a load, it is possible to effectively prevent the locking piece 16 from coming off or being torn.

In addition, in the second step, when the handle 17 is cut in the second disk 14 using the cut line 15, a finger hook hole 23 is formed in contact with one side of the cut line on both sides of the handle 17. Together, a penetrating forming process is carried out.

For example, when cutting the cut line 15 for forming the handle 17 in the central area of the second disk 12, the handle 17 is formed on both sides at a position in the middle of the length of the handle 17. A finger hook hole 23 of approximately trapezoidal shape, directly in contact with the area, is formed through the area.

The finger holder hole 23 formed in this way provides a space for the user's finger to enter when holding the handle 17. Accordingly, the user inserts his finger through the finger holder hole 23 and then holds the handle 17. ), allowing you to easily grab both sides of the width.

In addition, in the second step, when the handle 17 is cut into the second disk 14, the handle 17 is provided with a plurality of bending lines that are aligned along the width direction of the handle and at regular intervals along the length of the handle. The process of forming 24) can be carried out.

In this way, a plurality of bending lines 24 are formed on the handle 17 at regular intervals, so that the handle 17 that is drawn outward is naturally bent into an arc or arch shape by the bending lines 24. Therefore, when the user holds the handle 17, he or she can comfortably hold the handle 17 without any discomfort.

Of course, the locking piece 16 and the handle 17 formed on the second disk 14, the folding connection portion 18 and the folding connection line (25a, 25b), the reinforcing band 19, and the finger hook hole 23 ), bending lines 24, etc. can also be formed on the reinforcing paper 27, which is integrally attached to the second disk 14.

In this way, the locking piece 16, the handle 17, the folding connection 18, the reinforcing band 19, the finger hook hole 23, and the bending line 24 on the second disk 14 are formed using a press. It can be formed simultaneously through a single press operation through the cutting process, punching process, and press process in the facility.

That is, the fold line 11 formed on the second disk 14, as well as the locking piece 16 and the handle 17, the folding connection portion 18 and the folding connection fold lines 25a and 25b, and the reinforcing band ( 19), the finger hook hole (23) and the bend line (24) can be formed at the same time through a single press process of the press equipment, so the number of processes can be significantly shortened, and the original plate material can be used as a handle, etc. Scrap can be eliminated by using it, making it easier to manufacture and lowering costs, thereby improving manufacturability and economic efficiency.

In addition, in the second step, a process of forming a pair of folded pieces 22 in which three sides are cut and one side is attached to the first disk 26 using a cutting line can be performed.

For example, through a single press operation using a cutting process in a press facility, the bent piece 22 can be formed with three sides completely cut and one side attached to the first disk 26. There will be.

This bending piece (22) is bent inward (into the box) when you press both sides of the handle (17) with your fingers to hold the handle (17). Eventually, the bending piece (22) at this time is bent inward, creating a Since the fingers can be inserted deeply into both sides of the handle 17 using the space, the handle 17 can be easily gripped.

Of course, in the case of the bending piece 22, the locking piece 16 and the handle 17 on the second disk 14, the folding connection portion 18, the folding connection fold lines 25a and 25b, and the reinforcing band 19 , When forming the finger hook hole 23 and the bend line 24, they can be formed simultaneously through a single press operation through a cut line cutting process, a punching process, a press process, etc. in a press facility.

Next, as a third step, the first disk 26 and the second disk 14 are folded in two.

For example, adhesive is applied to the inner surface of the second disk 14 or the first disk 26, preferably the inner side of the second disk 14, and then used the fold line 11. A step of folding and adhering the first disk 26 and the second disk 14 in two is performed on the inside where each disk faces each other.

At this time, the adhesive can be a known hot melt adhesive, and can be applied over an appropriate area on the empty inner area of the second disk 14 (an area where a handle, etc. is not formed).

In this state, the first disk 26, the second disk 14, and the reinforcement paper 27 between them are folded in three layers, and the length of the first disk 26 (e.g., the length excluding the reinforcement bands on both sides) ) may have a length approximately similar to the length of the handle 17 excluding the locking pieces 16 at both ends. Accordingly, when the handle 17 is pulled for use, the locking piece 16 of the handle 17 is Since it is also caught at the longitudinal end of the first disk 26, it is possible to secure a solid locking state of the locking piece 16, and ultimately the problem of the handle 17 falling outward and being separated can be completely eliminated. There will be.

In addition, when folding and adhering the first disk 26, adhesive is applied to the inner surface of the reinforcement band 19 integrally formed at the end of the first disk 26, and then the adhesive is applied. The process of adhering the band 19 to the locking piece 16 at the end of the handle 17 is performed.

At this time, since adhesive is not applied to the connecting band 20, which is the portion between the first reinforcing band fold line 19a and the second reinforcing band fold line 19b, the first disk 26 and the reinforcing band ( Only 19) is adhered to the second disk 14 and the locking piece 16, and the connecting band 20 between the first reinforcing band fold line 19a and the second reinforcing band fold line 19b is in a floating state. , and later, the floating connecting band (20) is folded and erected to hold the handle (17).

Next, as a fourth step, the first disk 26 and the second disk 14, which are folded three times together with the reinforcement paper 27, are attached to the box top 102 of the packaging box 100. .

For this purpose, an adhesive such as hot melt is applied to the surface of the second disk 14, for example, excluding the handle portion and the catching portion, and the surface of the second disk 14 to which the adhesive is applied is wrapped. It is attached to the back side (inner side) of the box top 102 of the box 100.

When the second disk 14 including the reinforcing paper 27 and the first disk 26 is attached to the back of the box top 102 of the packaging box 100, through the hole in the box top 102 The handle 17 can be exposed upward.

Here, by applying the method of attaching the three-layer first disk 26, the second disk 14, and the reinforcement paper 27 to the back of the box top 102 of the packaging box 100, the packaging box It is very efficient in linking the process of attaching a paper handle during production to the packaging box production process.

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

6 to 8 are perspective and cross-sectional views showing a paper handle according to an embodiment of the present invention.

As shown in Figures 6 to 8, the paper handle is made of a three-layer laminated structure of a first disk 26, a second disk 14, and reinforcing paper 27, and the first disk 26 ) On the upper side of the handle (17) is a two-layer structure with reinforcing paper (27) attached. In fact, the handle (17) with a four-layer structure is exposed due to the two-stage folded portion (12), and the handle (17) ) The locking pieces 16 formed on both sides of the first disk 26 form two layers with the reinforcing bands 19.

Here, in the case of the reinforcing paper 27 attached to the back of the handle 17, the two-stage folded portions 12 on both sides of the reinforcing paper 19 are attached to the rear of the handle 17 to match the width of the handle. , it is possible to secure appropriate strength of the handle 17.

In addition, both locking pieces 16 of the handle 17 are attached to the second disk 14 by four folding joints 18 and are attached to the first disk 26 through the reinforcing band 19. connected to the side.

Accordingly, when the handle 17 is pulled upward, the locking pieces 16 on both sides are also pulled, and at this time, the folded connection portion 18 is folded by the folded connecting portion fold lines 25a and 25b and the second disk 14 ) and the locking piece 16, and the locking piece 16, which has been interfered with by the folded connection part 18, is fixed without being pulled upward any further, while the locking piece 16 is When pulled, the reinforcing band (19) that is integrally attached with it is also pulled together, and at the same time, the first reinforcing band fold line (19a) and the second reinforcing band fold line (19b) are folded, and eventually the handle (17) Since the reinforcing band 19 and the connecting band 20, which exert a supporting force, hold the locking piece 16 from the bottom, the handle 17 has the locking structure of the locking piece 16 on both sides and the reinforcing band ( 19) and the support structure of the connecting band 20 allows it to function as a handle while maintaining the pulled upward state.

That is, the paper handle includes reinforcing paper 27 attached to the back of the second disk 12, a folding connection portion 18 that is folded by folding connection fold lines 25a and 25b at both ends, and a handle drawing hole 13. A second disk (14) having a handle (17) with a hook (16) formed on the bottom of the plate, and a first reinforcing band fold line (19a) and a second reinforcing band fold line (19b) at both ends. The first disk 26, which has a reinforcing band 19 attached to the bottom of the locking piece 16 as it is folded, is sequentially overlapped from top to bottom to form a three-layer structure.

Therefore, when the handle 17 is pulled upward during use, the handle 17 is pulled upward, and the folding connection portions 18 on both sides are in a folded state, connecting the handle 17 and the second disk 14 and simultaneously connecting the handle 17 and the second disk 14. The movement is restricted by the folding connection portion 18, which is folded while moving while the locking piece 16 is pulled, and in addition, the reinforcing band 19 connected to the first disk 26 by the connecting band 20 is By holding the locking piece 16 of the handle 17 so that it is no longer pulled upward, the drawn-out state of the handle 17 is maintained and the user can hold the handle 17 and lift the packaging box.

In particular, in the case of the handle 17, appropriate self-strength can be secured by the reinforcing paper 27 attached to the rear side, that is, the reinforcing paper 27 including the two-stage folded portion 12, and thus Even when the weight of the packaging box is applied to the handle 17, problems such as the handle 17 breaking or falling off can be completely eliminated.

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

As shown in Figure 9, on the back side of the box top 102 of the packaging box 100, there is a paper handle ( When 105) is attached, the handle 17 is exposed through the handle withdrawal hole 101 of the packaging box 100.

In this state, when the box cover 103 of the packaging box 100 is closed, the handle 17 is exposed through the handle withdrawal hole 101 in the box top 102 and the hole in the box cover 103. appears, and then the box locking piece 104 is fastened to the box cover 103 to completely close the packaging box 100.

Meanwhile, when the user pulls the handle 17 to lift the packaging box 100, the folding connection portion 18 connecting the handle 17 and the locking piece 16 side to the disk side is bent and folded. Then, the locking pieces 16 on both sides slide inward towards the direction where the handle 17 is pulled.

When the locking piece (16), which was sliding in this way, is no longer dragged by the folded joint (18) and is caught, the handle (17) is no longer pulled out, and at this time, the handle (17) has a gentle arc. It forms an arch shape and is pulled out to an appropriate length, and the user can conveniently carry the packaging box 100 by holding the handle 17 protruding upward.

At the same time, when the locking piece 16 is pulled, the reinforcing band 19 is also folded by the first reinforcing band fold line 19a and the second reinforcing band folding line 19b and is pulled together with the locking piece 16. In this pulled state, the reinforcing band 19 is no longer pulled by the connecting band 20 and can be held on, so the handle 17 is no longer pulled out and can firmly maintain the pulled out state. .

At this time, even when a load is applied to the handle 17, the locking piece 16 of the handle 17 is integral with the handle 17 as well as the supporting force exerted by the folding connection portion 18 and the reinforcing band 19. It is possible to maintain a firm fixation state due to the self-strength of the attached reinforcing paper 27 made of Korean paper, and as a result, the handle 17 is also stably supported, even when the packaging box 100 weighs a lot. You can safely carry the packaging box 100 without worrying about the handle 17 breaking.

As such, the present invention provides a new manufacturing method that manufactures handles used in packaging boxes from paper materials, uses a single paper original plate, and completes paper handle products with minimal processes (cutting, bending, gluing, etc.). By doing so, disposal is easy as there is no need to separate the handle when discharging separately, and environmental pollution can be prevented by eliminating conventional synthetic resin handles. In addition, one sheet of paper disk can be folded or cut in batches. It can be manufactured using only a process, so it has excellent advantages in terms of manufacturability as well as economic efficiency.

In addition, in the present invention, the supporting rigidity of the handle is secured by adopting a folding connection connecting the handle side and the disk side as well as a reinforcing band and a connecting band connecting the handle side and the first disk side, so that heavy glass bottle products, etc. It can be useful as a handle for various types of packaging boxes.

In addition, in the present invention, when forming a handle using a cut line, the locking piece function is performed by using both ends of the original plate instead of forming a separate locking piece, which not only simplifies the manufacturing process and assembly process, but also reduces the generation of unnecessary scrap. At the same time, when manufacturing and assembling using an automated process, interference due to extra scrap adjacent to the stopping piece can be excluded as before, and linkage between processes can be secured. Manufacturability and productivity related to the automated process. can be improved.

In particular, in the present invention, reinforcing paper is attached to the back of the handle at the part where the two-stage fold is located to enable the handle to demonstrate appropriate strength, thereby preventing the handle from breaking or falling off even when the weight of the packaging box is applied to the handle. The problem can be completely ruled out.
