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

7 to 9 are perspective and cross-sectional views showing a paper handle according to an embodiment of the present invention

10 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 illustrating a method for manufacturing a paper handle according to an embodiment of the present invention.

As shown in FIGS. 1 to 6, the paper handle manufacturing method is to manufacture a paper handle product using a single sheet of paper disc having a predetermined thickness and to manufacture a paper handle product with a minimum process and a simple process. As a method, it is possible to improve manufacturability and economic efficiency through simplification of the process and reduction of production costs, etc., and in particular, it can be usefully used as a handle of a heavy packaging box without problems such as tearing or falling out by strengthening the support rigidity of the handle. There are features that make it possible.

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

The original paper plate 10 is a disk made of paper material that can be formed in various shapes such as square, rectangular, elliptical, circular, polygonal, etc. In the present invention, the original plate 10 made of a rectangular shape is applied.

The thicker the paper plate 10 for robustness, the better, but considering economic feasibility and moldability, it may be made of a thickness of about 0.1 to 1.5 mm, and from a practical point of view, a thickness of about 0.4 to 0.6 mm. It is preferable to apply a paper disc 10 made of.

At this time, at one end of the paper disc 10, for example, on either long side of both long sides, a reinforcing plate 28 having a rectangular plate shape having a relatively small area compared to the paper disc 10 is provided. It is integrally formed, and the reinforcement plate 28 can take a form integrally connected to the paper original plate 10 side by the reinforcement plate folding line 29 forming the boundary with the paper original plate 10.

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

And, when forming the reinforcing plate 28, reinforcing parts, that is, substantially "T" shaped reinforcing bands 19 are cut together at both ends in the longitudinal direction of the reinforcing plate 28, thereby forming the reinforcing plate 28 The reinforcing strip 19 is integrally formed at both ends of the.

Next, as a second step, a step of forming the handle take-out hole 13 and the handle 17 on the paper disc 10 is performed.

To this end, a folding line 11 parallel to the longitudinal direction is formed in the middle of the width of the original paper plate 10 .

That is, a linear folding line 11 parallel to the length L of the paper disc 10 is formed at a point where the width W of the rectangular paper disc 10 is divided in half.

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

The folding line 11 at this time can serve as a reference line when folding the original paper plate 10 into two layers in the third step to be described later.

By forming the folding line 11 in the middle of the width of the original paper plate 10 in this way, the original paper plate 10 is divided into two areas, that is, the first original plate 12 on one side and the second original plate 14 on the other side. .

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

Here, the handle take-out hole 13 may be formed in the form of a rectangular hole formed side by side along the length direction of the disc in the central region of the first disc 12 .

The width of the handle drawing-out hole 13 may be equal to or slightly larger than the width of the handle 17, and the length of the handle drawing-out hole 13 may be relatively shorter than the length of the handle 17. can

At this time, the second step may further include a process of forming a finger hook hole 23a for holding the handle 17 when the handle lead-out hole 13 is formed through the first disc 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 disc 12, the handle take-out holes 13 are formed on both sides of the handle take-out hole 13 at an intermediate position in the length of the handle take-out hole 13. A substantially trapezoidal finger hanging hole 23a through and through is formed together.

The finger hanging hole 23a formed in this way provides a space for the user's fingers to enter when holding the handle 17, and thus the user puts his or her finger through the finger hanging hole 23a and then inserts the handle 17. ) can be easily grasped on both sides of the width.

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

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

The handle 17 is a long rectangular paper strip, which is made by using a part of the paper disc 10 as it is, and has a shape corresponding to the outer shape of the handle 17 and a cutter (not shown) that moves up and down. 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, along the outer shape of the long strip-shaped handle part of a certain width excluding the engaging pieces 16 at both ends, along with the lengthwise direction of the handle The handle 17 can be separated from the second disk 14 side except for a part by two lines of parallel cut lines 15 and can be distinguished.

At this time, the formation position of the handle 17 is the formation position of the handle withdrawal hole 13 formed in the first disc 12 when the first disc 12 and the second disc 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 at this time, the locking pieces 16 are also made by using a part of the paper original plate 10 as it is.

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

Here, the width of the locking piece 16 is made relatively large compared to the width of the handle 17 and the width of the handle withdrawal hole 13, and accordingly, when the handle 17 is withdrawn, the handle 17 When the handle exits through the take-out hole 13, the locking piece 16 does not follow along and can be caught.

In particular, in the second step, when incising and molding the handle 17 using the cut line 15, in order to prevent complete separation of the handle 17, a total of 4 pieces, 2 on each side for connection with the second disc 14 side A belt-shaped folding connection portion 18 is formed.

For example, the integral hooking piece 16 and the handle 17 are incised while leaving the folding connecting portion 18 formed parallel to the length of the handle between both sides of the hooking piece 16 and the second disc region. do.

That is, the cutting line 15 for forming the integral hooking piece 16 and the handle 17 does not continue, and the cutting line 15 is cut at the portion where the folding connecting portion 18 connects to the second disk side, so that the integral type The hooking piece 16 and the handle 17 are cut and formed.

In this way, the hooking piece 16 and the handle 17 are not completely separated from the second disc 14 side and connected to the second disc 14 side using the folding connection part 18, so that the subsequent process (eg, When the process of applying adhesive, the process of folding in two layers, the process of attaching to the packaging box side, etc.) is performed, the second disc ( 14) The position of the phase can be adhered to, and in the end, benefits such as allowing the subsequent process to be performed accurately and smoothly can be obtained.

In addition, when the handle 17 is formed using the cut line 15, both ends of the second disc 14 are used as they are without forming a separate hooking piece by making a cut line 15 on the second disc 14. By making the hooking piece 16, it is possible to simplify the manufacturing process and assembly process, as well as reduce unnecessary scrap generation, and at the same time, when manufacturing and assembling using an automated process, as before, excess scrap adjacent to the hooking piece (second It is possible to exclude interference caused by disk scrap).

In addition, when the handle 17 is pulled out, the folding connecting portion 18 is formed at the boundary with the second disc 14 side and the boundary with the engaging piece 16 side, respectively. 25b)), it is located between the second disc 14 and the locking piece 16, overlaps, and exerts a supporting force in the folded state, so that the handle 17 side is attached to the second disc 14 side. By doing so, the handle 17 can exhibit enhanced support rigidity, and eventually, the handle 17 is firmly supported by the second disk 14 via the folding connection portion 18, thereby reducing the load caused by the packaged product. Even in the case of this action, it is possible to maintain a solid support rigidity.

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

In addition, in the second step, while maintaining a certain distance from each other at the boundary between the reinforcing strip 19 and the reinforcing plate 38 for folding of the reinforcing strip 19 integrally formed at both ends of the reinforcing plate 38 Two rows of folding lines parallel to each other along the reinforcing strip width direction, that is, the first reinforcement strip folding line 19a and the second reinforcement strip folding line 19b are formed, and at the same time, the first reinforcement strip folding line 19a and the second reinforcement band It includes the process of forming the connecting strip 31 made between the strip folding lines 19b.

Accordingly, when the folding connecting portion 18 is folded while the hooking piece 16 is pulled by the pull of the handle 17, the reinforcing strip 19 attached to the hooking piece 16 is also pulled together. As the first reinforcement strip folding line 19a and the second reinforcement strip folding line 19b are also folded together, the portion between the first reinforcement strip folding line 19a and the second reinforcement strip folding line 19b, that is, the connection strip ( 31) is erected vertically and exerts a holding force at the same time, and eventually the locking piece 16 is held on the side of the reinforcing plate 38 together with the reinforcing strip 19, and the load acting on the handle 17 Even when the hooking piece 16 is pulled upward by the hooking piece 16, it is possible to effectively prevent the problem of falling out or tearing while the hooking piece 16 is separated.

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

For example, when making a cut line 15 for forming the handle 17 in the central region of the second disk 12, the handle 17 is formed on both sides at the midpoint of the length of the handle 17 An approximately trapezoidal finger hanging hole 23b in contact with the area is formed through the same.

Here, the finger hanging hole 23b formed in the second disc 14 when the first disc 12 and the second disc 14 are folded in two with respect to the folding line 11 is the first disc ( The finger hanging holes 23a formed in 12) can be aligned at the same position.

The finger hook hole 23b formed in this way provides a space for the user's fingers to enter when holding the handle 17, and accordingly, the user puts his or her finger through the finger hook hole 23b and then inserts the handle 17. ) can be easily grasped on both sides of the width.

In addition, in the second step, when the handle 17 is incised on the second disc 14, a plurality of fold lines arranged at regular intervals along the handle width direction and at regular intervals along the handle width direction on the handle 17 ( 24) can be carried out.

In this way, as a plurality of fold lines 24 are formed at regular intervals on the handle 17, the handle 17 drawn outward is naturally bent in an arc shape or an arch shape by the fold line 24 When holding the handle 17, the user can comfortably hold the handle 17 without any discomfort.

In this way, the forming of the hooking piece 16 and the handle 17, the folding connecting portion 18, the reinforcing strip 19, the finger hanging hole 23b, and the folding line 24 on the second disk 14 is press Through the cutting process, punching process, press process, etc. in the facility, it can be simultaneously molded by one press operation, and at the same time, the handle withdrawal hole 13 on the first disc 12, the finger hole 23a The molding of can also be simultaneously molded by a punching process in a press facility or the like.

That is, the folding line 11 formed on the first disc 12 and the second disc 14, as well as the holding piece 16 and the handle 17, the folding connection part 18 and the folding connection

part folding line

25a , 25b), reinforcing strip 19,

finger hanging holes

23a, 23b, fold line 24, and handle lead-out hole 13 can be formed simultaneously by the one-time press process of the press equipment, so that the process The number can be greatly reduced, and since scrap can be eliminated by using the original plate material as it is as a handle, etc., it is possible to improve manufacturability and economic feasibility, such as easy manufacturing 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 to the reinforcing plate 28 using a cutting line may be performed.

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

When the both sides of the handle 17 are pressed with fingers to hold the handle 17, the bent piece 30 is bent inward (inside the box), and eventually the bent piece 30 at this time is bent inward. Since the fingers can be deeply inserted into both sides of the handle 17 by using the space, the handle 17 can be easily gripped.

Of course, even in the case of the bending piece 30, the holding piece 16 and the handle 17 on the second disk 14, the folding connection part 18 and the folding connection

part folding line

25a, 25b, reinforcing strip 19 , When forming the finger hanging hole 23b and the fold line 24, it can be simultaneously formed by one press operation through a cutting line cutting process, a punching process, a press process, etc. in a press facility, and at the same time, the first Forming of the handle take-out hole 13 and the finger hanging hole 23a on the disk 12 may also be simultaneously formed 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, the adhesive 20 is applied to the inner surface of the second disc 14 or the first disc 12, preferably the inner surface of the second disc 14, and then the fold line 11 Using the step of folding and bonding the first disc 12 and the second disc 14 in two layers to the inside where each disc is in contact with each other.

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

Next, as a fourth step, after applying the adhesive to the inner surface of the reinforcing plate 28, the reinforcing plate 28 is folded toward the outer surface of the second original plate 14 using the reinforcing plate folding line 29. Adhesion steps are performed.

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

At this time, the length of the reinforcing plate 28 may be made of a length approximately 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 hooking piece 16 of 17) is also hooked on the longitudinal end of the reinforcing plate 28, it is possible to secure a solid hooking state of the hooking piece 16, and eventually the handle 17 slips outward. It is possible to completely rule out the problem of deviation.

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

In addition, when the reinforcing plate 28 is folded and adhered, at the same time, after applying the adhesive to the inner surface of the reinforcing strip 19 integrally formed at the end of the reinforcing plate 28, the reinforcement applied with the adhesive in this way A process of bonding the strip 19 to the hooking piece 16 at the end of the handle 17 is performed.

At this time, since adhesive is not applied to the connection strip 31, which is a portion between the first and second reinforcement

strip folding lines

19a and 19b, the reinforcing plate 28 and the reinforcing strip 19 ) is adhered to the second disk 14 and the hooking piece 16, and the connecting strip 31 between the first reinforcing strip folding line 19a and the second reinforcing strip folding line 19b is in a floating state. And, later, the floating connection band 31 is folded and erected so that the handle 17 can be held.

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

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

When the three-ply first disc 12, the second disc 14, and the reinforcing plate 28 are attached to the back side of the box top plate 22 of the packing box 21, the hole of the box top plate 22 Through this, the handle 17 can be exposed upward.
