Description

Packaging box {PACKING BOX}

The present invention relates to a packaging box, and more particularly, to a packaging box, which has a structure in which protrusions and grooves are formed on upper and lower outer covers of a packaging box so as to correspond to each other and are coupled to each other, Taping work can be performed concurrently, and when the package is used for courier dispatch, etc., the upper coupling part can be sealed by attaching only a sticker such as an invoice.

The packaging box, which is mainly used frequently, is composed of a six-sided body, which is composed of a four-sided body portion and an upper-side lid lower-side lid portion which determine an inner space, and each portion is divided into an upper- The boundary between the cover surface and the body surface boundary, the lower cover surface and the body surface is formed in a straight line so as to be easily bent, and each cover surface is cut and divided into the same length between adjacent surfaces. Four sides are combined by the body coupling portion.

Packing boxes are unfolded on one side and two sides. In order to use this packing box, it is necessary to spread the contact area so that the boundary between the one and two sides and the boundary between the three sides and the four sides are covered by the incision And a lower inner lid having a shorter length on the lower side is folded inward by a folding line and the lower outer lid is folded by a folding line on the upper layer, And the lower side is sealed. The upper inner lid having a shorter length on the upper side is folded inward by a folding line and the upper outer lid is folded by a folding line on the upper layer, The front end of the lid facing each other is attached, and the upper side is sealed to complete the packaging.

A difficult process during this process is difficult in the process of bending the inner lid and then bending the outer lid to the upper lid and sealing it with the adhesive tape because of the problem that the abutting edge of the outer lid is not constantly abutted each time It is difficult to seal with the adhesive tape due to the unfolded state of the outer cover and the unfolded state of the outer cover. In addition, since the ends of the outer covers meet each other in a straight line, If you use a knife when opening the contents may cause damage to the problem.

In order to solve such a problem, Korean Patent Registration No. 10-1592826 discloses that a catching protrusion protruding from the outer edge of both outer wings and a catching recess corresponding thereto are formed, and are formed to be shorter than half of the widths of both outer wings It is caught between the leading edges of both sides. When the box is packed, both sides of the body are pushed inward. When the outer wings of both sides are folded, the tip of each end of the wing is brought into contact with each other, and the jaws and the catching grooves are engaged with each other. When both side surfaces of the body portion are restored, the outer wings of both sides are not opened upward due to the pulling force to the outside, and the engagement state is maintained so that both hands can be freely used without grasping the outer wings of both sides, Is an invention.

In the present invention, in order to engage the latching jaw and the latching groove, not only the process of pushing the both sides of the body part inward but also the basic problem is not solved.

And Korean Utility Model Registration No. 20-0381435 discloses that the package box structure is formed in a regular corrugated shape in which the free end edges of the outer cover are mutually engaged with each other. .

And the root cause of the reopening of the outer cover, which is a problem, can not be solved, and the necessity of improvement of the packaging box still remains as a homework.

Korean Patent Registration No. 10-1592826 Korea Utility Model Registration No. 20-0381435

It is an object of the present invention to overcome the above-described problems, and it is an object of the present invention to provide a packaging box which is made of the same material as that of the packaging box but does not open again when the outer cover is folded, In addition, it is possible not only to reduce the working time but also to function as a packaging box without using an adhesive tape, and to use the adhesive tape if necessary. In addition, in this case, the packaging box is more tightly bonded, To provide a box which can contribute to environmental protection by helping to reduce the cost by using less adhesive tape and also by recycling.

In order to accomplish the above object, the packaging box according to the present invention is a packaging box which is generally manufactured by using corrugated cardboard obtained by adhering a paperboard to the outside of a corrugated cardboard with wave-shaped corrugated do.

The difficulty that arises in the process of bending the inner lid mentioned above and folding the outer lid to the upper layer and sealing it with the adhesive tape is a problem that the outer lid is unfolded without being bent.

The reason is that the outer lid is bent on the inner lid, because each fold line is straight. As a result, when the inner lid is folded on the inner lid, the inner lid acts as a pushing force of the outer lid, so that the outer lid can not maintain the bending state and is unfolded again. In this state, it is difficult to attach the adhesive tape by itself. Further, since the tip of the outer lid is linear, the adhesive tape is attached in a state of being twisted and lifted. In addition, since the tip of the outer lid is linear, the cutter knife is mainly used in the process of opening the packing box. The blade is thin and can be deeply penetrated to the inside, which may damage the contents.

In order to solve this problem, in order to prevent the outer lid from being unfolded again, the outer lid is folded by the thickness of the inner lid so that the force of the inner lid does not extend beyond the outer lid, .

In order to solve this problem, the protrusions and corresponding grooves are formed at the ends of the outer lid, respectively, so that the outer lid is fixed to the outer lid, So that the packaging box can not be broken.

In addition, such a structure maintains the combined state without sealing with the adhesive tape due to the combination of the projections and the grooves, and a function of preventing the cutter blade from damaging the contents when the packaging box is opened can be additionally provided.

As described above, the packaging box of the present invention solves the problem caused by the force to unfold the outer cover in the process of packaging, so that the packaging box can be packaged alone without any additional device or help. And it can function as a packing box without using adhesive tape. If you use adhesive tape when you use it as a packing box for delivery of courier, etc., the binding strength of the packing box is strengthened, And it is advantageous not only for convenience of operation and shortening of working time but also for economic effect and environmental protection by saving adhesive tape.

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

As shown in FIG. 1, the packaging box can be generally divided into a body 100, a lower lid 200 and an upper lid 300. The body 100 has a body surface 120 The lower lid part 200 formed on the lower side of the body part 120 includes a lower lid 1 260, a lower inner lid 1 220, The lid 2 280 and the lower inner lid 2 240 are formed in an extended sequence and are divided by a lower lid incision 221 cut between the lower side lids and the body side 120 and each lower side And a lower folding line 222 is formed at the boundary with the cover.

The upper lid 300 formed on the upper side of the body surface 120 includes an upper lid 1 360, an upper lid 1 320, an upper lid 2 380, an upper lid 2 340, And an upper curved line 322 is formed at the boundary between the body surface 120 and each upper lid. The upper lid 321 is formed by extending the upper side lid 321, . In this state, when the outer side of the body joint part 140 is joined to the inner side end of the body side 120, the manufacture of the packaging box is completed and the center part of the body side 120 is stored in a folded flat state.

The unfolded surface is deformed into a square pipe shape by the lower cover cutout portion 221 and the upper cover cutout portion 321 which are formed on the same line, When the lower inner lid 2 (240) facing the lid 220 is pressed inward, the upper lid 220 is bent by the lower folding line 222 to maintain the state. When the lower outer lid 2 280 facing the lower outer lid 260 is pressed inwards, the lower lid is bent by the lower curved line 222. At this time, the unfolding phenomenon occurs again. The lower adhesive tape 420 may be bent in an uncomfortable posture such as a hand or a tool that presses the lower outer cover 1 260 and the lower outer cover 2 280 in order to attach the lower adhesive tape 420, There is a difficulty to attach.

Next, the packaging box is turned upside down to hold the contents, and when the upper inner lid 2 (340) facing the upper inner lid 320 is pressed inward, it is bent by the upper folding line 322 to maintain the state. Then, when the upper outer lid 2 (380) facing the upper outer lid 1 (360) is pressed inwards, it is bent by the upper fold line 322. At this time, The upper adhesive tape 440 is held in an uncomfortable posture such as pressing or pressing with the knee to press the upper outer lid 1 360 and the upper outer lid 2 380 to attach the upper adhesive tape 440, There is a difficulty to attach. Fig. 3 shows the packaging state.

Another problem in the above operation is that the shape of the packaging box is not constant because the outer lid is easy to turn. In addition, we use mainly cutter knife to open the packing box, and the knife blade can be deeply inserted, which may damage the contents inside.

In view of the factors causing such a problem, the reason why the outer covers 260, 280, 360, and 380 are unfolded first is that the folding lines 222 and 322 are formed in a straight line. The reason why the packaging box is not constant is that the tips of the outer covers 260, 280, 360, and 380 are linear, which may cause damage to the contents by the cutter blade.

An embodiment for solving the above problem will be described with reference to an exploded view of a packaging box according to an embodiment of the present invention.

The improvement body section 500 can be divided into an improvement body section 500, an improvement lower cover section 600 and an improvement upper side cover section 700. The improvement body section 500 has a body joint section 140, And an improved lower lid 600 formed below the improved body surface 520 includes an improved lower lid 1 660, an improved lower inner lid 1 620, an improved lower outer lid 2 680, The inner lower lid 2 640 is formed in an extended sequence and the lower inner lid 1 660 and the lower inner lid 2 680 have a trapezoidal outer lower lid protrusion 624, And an improved lower outer cover groove 625 having a trapezoidal shape with a longer outer side is formed inwardly at the other ends of the improved lower lid 1 660 and the lower improved lid 2 680, Is divided by a lower lid cutout (221) cut between the lids and is provided with an improved body surface (520), an improved inner lid (620) A lower folding line 222 is formed on the boundary with the inner lid 2 640 in the same line and an improvement is made at the boundary between the body side surface 520 and the improvement lower outer lid 1 660 and the lower improvement inner lid 2 680 And the lower and upper curved lines 623 are formed in the same line below the lower curved line 222 by the thickness of the corrugated cardboard material.

The improved upper side lid 700 formed on the upper side of the improved body surface 520 includes an improved upper side lid 1 760, an improved upper side lid 1 720, an improved upper side lid 2 780, An inner upper lid 2 740 is formed in an extended sequence and an improved upper lid protrusion 724 having a trapezoidal outer shape is formed at the tips of the outer upper lid 1 760 and the outer upper lid 2 780 And an improved upper side cover groove 725 having a trapezoidal shape with a longer outer side is formed inward at the other end of the improvement upper side lid 760 and the upper side of the improvement upper side lid 2 780, And an upper fold line 322 is formed at the boundary between the improved body surface 520 and the inner upper lid 1 720 and the inner upper lid 2 740, Is formed on the same line, and the improvement upper outer side 1 (760) and the improvement upper side lid 2 (780) are formed at the boundary between the body side surface 520 and the improvement upper side lid 1 On curve 723 by a cardboard material thickness than the upper curved section 322 it is formed in the same line.

In this state, when the outside of the body joint part 140 is joined to the inner front end of the improvement body surface 520, the improvement packaging box is completed as shown in FIG. 5 and the middle part of the improved body surface 520 is stored in a folded flat state .

In order to use the improvement packing box, when the flat facing surface is opened, the unfolded surface is deformed into a square pipe shape by the lower cover cutout portion 221 and the upper cover cutout portion 321 formed on the same line, When the inner lower lid 2 (640) facing the inner lid 1 (620) is pressed inward, the upper lid (620) is folded by the lower curved line (222) Then, when the improvement lower outer cover 2 (680) facing the lower inner cover 1 (660) is pressed inward, the lower inner cover 1 (660) is bent by the lower inner cover curved line 623, Since the lower outer lid 2 680 is bent upward by the thickness of the inner lid 620, 640, the pushing force is not generated by the inner lid 620, 640 and the bending state is maintained. The lower inner cover lid 660 and the lower inner lid protrusion 624 formed in the lower inner cover lid 680 are pressed into the outer lid groove 625 to be joined and held together And it is not necessary to perform the function of the packaging box without attaching the lower adhesive tape 420. After the contents are contained in the packaging box, the upper side inner folding lid 2 (740) facing the inner side lid 1 (720) is bent inward by pressing the upper side folding line 322, . The improvement upper outer lid 760 is then folded by the upper outer folding fold line 623 when it is pressed inwards to face the improvement upper outer lid 760. At this time, Since the upper outer lid 2 780 is bent upward by the thickness of the inner lid 720, 740, the pushing force is not generated by the inner lid 720, 740, The remedial upper lid 760 and the remedial upper lid protrusions 724 formed on the remedial upper lid 2 780 are pressed into the remedial outer lid grooves 725 to be engaged with each other to maintain the state So that there is no shortage in function of the packaging box without attaching the upper adhesive tape 440. This state is shown in Fig.

As a result, the shape of the packaging box has a constant shape, and since the shape of the tips of the improved outer covers 660, 680, 760, and 780 is not linear, the problem that the contents are damaged by the cutter blade may be a complement .

FIG. 7 is a state in which the lower adhesive tape 420 and the upper adhesive tape 440 are added to the lower side of the improvement packaging box, if necessary, to prevent the contents from being lost.

8 shows a case where the lower adhesive tape 420 is affixed to the lower side of the improvement packaging box to prevent the contents from being lost, and the upper side adhesive tape 440 is not attached to the upper side, and the courier invoice 460 ), It is possible to fulfill its function only by sticking of stickers, etc. Also, it can function as an industrial packaging wrap, which has a weak adhesive force to the packaging box due to its weaker adhesive force than the adhesive tape by another means. Not only will it help to open the package, but it can also be a great help in separating and recycling.

9 is a developed view of another packing box according to the embodiment of the present invention. FIG. 9 is a developed view of the improved inner cover 620, 640, 720, 780 formed by extending the height of the improved outer cover 1 (720) The lower inner cover 3 (820) and the lower inner improve cover (840) are formed so as to be in contact with each other when the inner upper lid 3 (920) and the inner lid 4 (940) to be. This improves the ease of stacking of several items as the floor of the other packing box becomes flat, and it is not only necessary to insert the interlayer cardboard but also to prevent the floor from sagging. The upper side has the same advantage, and the function to protect from the cutter blade can also be enhanced.
