Description

Prefabricated packaging box {Prefabricated packaging box}

The present invention relates to a packaging box that is assembled in a folded manner by forming a fold line at the folded area of a single sheet of cardboard. More specifically, the present invention relates to a packaging box that transports small items of small volume and light weight or that contains fixing brackets for the contents for courier delivery. By preventing excessive movement in the unused state, work time is shortened when packaging the contents, and the assembled packaging box is sealed using a delivery invoice, eliminating the need for a separate sealing process. It relates to a prefabricated packaging box that provides great convenience to users by providing a stress that can withstand the compressive strength transmitted from the upper direction by the weight of the loaded product.

Most general packaging boxes have side wall plates of the same height on the front, back, left, and right sides, a bottom plate at the bottom of the side wall plate, and a cover that can be easily opened and closed at the top of the side wall plate. .

Additionally, there is a problem in that the joints for connecting and fixing the side wall plates of the packaging box must be glued together or fixed using fixing means such as staples.

In addition, the box shown in Figure 1 is widely used as a prefabricated packaging box used to store or deliver small items of small volume and light weight.

That is, the prefabricated packaging box as shown in FIG. 1 is made of a single cardboard material, has folding lines for folding at required areas, and has a plurality of assembly wings and assembly holes formed at areas requiring assembly.

In more detail, long holes 11a, 12a, and 13a for assembly are drilled in the left side plate 11, right side plate 12, and front side plate 13 of the bottom piece 10, respectively, and the left side plate 11 ), the left side piece (11b) and the reinforcing side piece (11c) extending from ) are formed integrally, and the central portion of the reinforcing side piece (11c) is accurately inserted into the long hole (11a) for assembly of the left side plate (11) to form the packaging box itself. Assembly wings 11d are protruding to strengthen the side wall plates.

Also, the right side plate 12 has the same configuration as that of the left side plate 11, and a right side piece 12b, a reinforcing side piece 12c, and an assembly wing 12d are protruded.

Meanwhile, the rear side plate 14, the cover plate 15, and the front reinforcement piece 16 are formed integrally with the upper part of the bottom piece 10, and the side joint pieces 13a are formed on both sides of the front side plate 13 ( 13b) are each extended, and side joints 14a and 14b are each extended on both sides of the rear side plate 14, and cover joints 15a and 15b are formed on both sides of the cover plate 15. These are each extended, and front joint pieces 16a and 16b are formed on both sides of the front reinforcement piece 16, and in the center of the front reinforcement piece 16, there is a long hole for assembling the front side plate 13 ( The assembly wing (16d) fitted into 13a) is protruding, so that the assembly wing (16d) of the front reinforcement piece (16) is inserted into the assembly long hole (13a) of the front side plate (13), thereby forming the assembly packaging box. Assembly is complete.

Since the packaging box for assembly of the above configuration is widely known and widely used, the assembly method will not be described in detail. However, during assembly, the side joints (13a) (13b) (14a) (14b), the left side plate (11) and In the process of assembling the right side plate 12, it is necessary to insert the assembly wings 11d and 12d protruding from the reinforcement side pieces 11c and 12c into the long holes 11a and 12a for assembly, respectively, so it is necessary to be skilled in the assembly work. Even so, it takes quite a bit of time, which ultimately causes labor costs to rise.

The above-mentioned assembly packaging box is made by inserting the contents of the storage or delivery item into the assembled box with the cover plate 15 opened, and then connecting the cover joints 15a and 15b of the cover plate 15. While inserting the front joint piece (16a) (16) of the front reinforcement piece (16) into the inner side of the box, the assembly wing (16d) of the front reinforcement piece (16) is inserted into the assembly long hole (13a) of the front side plate (13). If the courier is inserted from the outside using the pressure fitting method, the package can be sent. In this state, a third party can open the cover plate 15 and withdraw the contents, so in most cases, the assembly wing 16d The connecting portion of the assembly hole 13a is sealed with a sticker or the like to enable a third party to check whether the cover plate 15 has been opened.

The present invention is a small item with a small volume, for example, when packaging various types of contents such as smartphones, cases needed when using smartphones, stands, accessories used incidentally, stationery, cosmetics, etc., a separate fixing metal is used. By allowing small contents to be easily inserted and fixed in a stable state without the need for an assembled box, the assembled box containing the contents can be stored in a delivery vehicle even if the weight of other heavy delivery items is transferred from the top of the assembled box. There is enough stress to withstand the concentrated load due to its own weight, providing great convenience to workers and users.

The present invention to achieve the above object is to store the contents of a thin and light article in single or multiple prefabricated packaging boxes or to transport them by courier, by using the contents of the box as a separate cushioning material. Working time to pack the contents in a packaging box without wrapping them or filling the space formed between the contents and the inside of the box with a separate cushioning material to prevent the contents from flowing too much in the inner space of the box and without damaging the contents. In addition to shortening the packaging, the prefabricated box can sufficiently withstand the concentrated load of other heavy products placed on top, preventing the packaging box from being crushed or damaged.

When delivering small contents of small volume and light weight by courier, there is a lot of space between the inner part of the delivery box and the contents, so a space is not created by wrapping the exterior of the contents with cushioning material or filling the inner space of the box with separate cushioning material. It is common to avoid this.

Accordingly, the present inventor proposes that when the contents for delivery are small in volume and light in weight, especially when the thickness of the contents is thin, or when the above-mentioned contents are multiple, etc., when folding a single sheet of cardboard to form a packaging box, the cover of the packaging box The position and shape of the upright piece, which is formed integrally with the piece, changes depending on the type and quantity of the contents and presses the top surface of the contents, thereby preventing the contents from flowing excessively, shortening the packaging time of the contents and requiring separate packaging. It has the effect of providing many economic benefits to users by eliminating the hassle of preparing and working with cushioning materials.

In addition, even if another heavy delivery box of the present invention is placed on top of the packaging box containing the contents and a concentrated load is transmitted, the exterior of the packaging box is not distorted or damaged, which may occur due to damage to the packaging box during delivery. Problems that arise can also be prevented in advance.

According to FIGS. 2 and 3, the second joint piece 112 and the second cover piece 160 extend integrally to the upper part of the bottom piece 110 formed as a single piece, and the first joint piece extends to the lower part of the bottom piece 110. The piece 111, the first cover piece 150, the first erection piece 151, and the second erection piece 152 are extended as one piece, and then the left side plate 120 and the right side plate of the bottom piece 110 are formed. Both side and side portions of (220) are extended as short as the length of both sides (h2), and at the center of the length of the bottom piece 110, they are extended as long as the center length (h3), so that the left side plate 120 and the right side plate 220 are The central portion is high and the side portions are low, forming a pentagon with slopes (131) (141) (231) (241).

And a left first reinforcement plate 130 and a left second reinforcement plate 140 extending in a direction perpendicular to the inclined surfaces 131 and 141 of the left side plate 120 are formed, and the inclined surface of the right side plate 220 ( 231) A right first reinforcing plate 230 and a right second reinforcing plate 240 extending in a direction perpendicular to (241) are formed.

In the above, the width (h4) of the left first reinforcement plate 130 and the right first reinforcement plate 230 is larger than the width (h5) of the left second reinforcement plate 140 and the right second reinforcement plate 240. It is desirable to form it because it is to facilitate work when assembling the present invention to use it as a delivery box.

That is, the process of assembling the present invention into a delivery box is described in detail as follows.

First, the side plates 120 and 220 on both sides of the bottom piece 110 are folded toward the bottom piece 110, and the first left side plates 131 and 231 extend on the inclined surfaces 131 and 231 of the both side side plates 120 and 220. The reinforcement plate 130 and the right first reinforcement plate 230 are folded inward, and then the first cover piece 150 is folded inward, and the left first reinforcement plate 130 and the right first reinforcement plate 230 are folded inward. It is formed extending from the end of the first cover piece 150 on the inner surface 132 (232) and folds the first erection piece 151 and the second erection piece 152 having inclined portions 157 and 158. bend it to do so.

In the above, the first erection piece (151) and the second erection piece (152) tend to return to their original positions due to their own elastic force, so the first and second erection pieces (151) (152) face upward. It is slightly erected, and at this time, when the left and right second reinforcement plates 140 and 240 extending on the inclined surfaces 141 and 241 of the left side plate 120 and the right side plate 220, respectively, are folded inward, The connection surfaces (142) (242) of the left and right second reinforcement plates (140) (240) are connected to the first and second erection pieces (151) (152), and the first and second erection pieces (151) (152) are connected to the first and second erection pieces (151) (152). ) is prevented from being erected toward the top.

In the above state, the second cover piece 160 is folded inward toward the bottom piece 110 and the left and right second reinforcing plates 140 and 240 are pressed while the assembly wings 161 of the second cover piece 160 are pressed. ) is inserted into the wing insertion hole 153 drilled between the first cover piece 150 and the central portion of the first and second stand pieces 151 and 152, the assembly of the box 100 is completed.

In addition, the cut portions 133 and 233 in the shape of cutting the corner portions where the inner surfaces 132 and 232 of the left and right first reinforcement plates 130 and 230 are located are used as the second reinforcement plates 133 and 233 during assembly of the present invention. It was revealed that this is to form a space so as not to impede the entry of the assembly wing 161 when the assembly wing 161 of the cover piece 160 is inserted into the wing insertion hole 153 of the first cover piece 150. put it

In addition, the reason for forming the notches 155 and 165 at the end corners of both sides of the first cover piece 150 and the second cover piece 160 is to place the contents to be packaged on the bottom piece 110. , set the left and right side plates 120 (200) upright in the upward direction, then fold the left and right first reinforcement plates (130) (230) inward, and first reinforce the left and right sides with the first cover piece (150). In the process of covering the upper surface of the plate (130) (230), the end corners of both sides of the first cover piece (150) protrude outside the left and right first reinforcing plates (130) (230), thereby damaging the appearance. This is to prevent the end corners of both sides of the second cover piece 160 from protruding outside the left and right second reinforcing plates 140 and 240 due to the cutout portion 165, thereby damaging the appearance. am.

The thickness of the second cover piece 160 is provided on both sides of the wing insertion hole 153 of the above-described first cover piece 150 to facilitate the insertion of the wings 161 for assembly of the second cover piece 160. A bending line 156 is formed that maintains a constant width (t) corresponding to .

Meanwhile, the inside of the box 100 assembled on one or both sides of the first and second joint pieces 111 and 112 formed between the bottom piece 110 and the first and second cover pieces 150 and 160. In order to easily remove the contents, it is desirable to form a perforation line 171 so that the user can easily tear the protruding piece 170 on either side of the first and second joint pieces 111 and 112. something to do.

Therefore, in the present invention, the protruding piece 170 is integrally protruded on one side of the second joint piece 112 located between the bottom piece 110 and the second cover piece 160, and the bottom piece 110 and , the fold line formed between the second cover pieces 160 is shown as an example in which a cut line 171 is formed that can be easily torn.

Most of the prefabricated packaging boxes of the present invention described above are small in volume and light in weight, and are used when sending small contents by courier. The small contents include smartphones, cases, stands, accessories and stationery necessary for use of smartphones, Examples include cosmetics, etc. In the conventional case, in order to send the above-mentioned contents by courier, the exterior of the contents is wrapped with a cushioning material to prevent the contents from flowing inside the box, or the contents are placed in the space between the inside of the box. This is to solve the problem of taking a lot of time during packaging work by adopting a method of eliminating space by filling the area with cushioning material.

In particular, in the present invention, in a box assembled according to the type of contents, the first erection piece 151 and the second erection piece 152 of the first cover piece 150 change their positions and shapes depending on the type of contents, thereby increasing the contents. This has the effect of pressing or supporting the upper surface of the contents to prevent them from flowing, so there is no need to surround the contents with separate cushioning material or fill the inner space of the box with separate cushioning material when putting the contents for delivery into the prefabricated box of the present invention. This is explained in detail according to the type of content.

The embodiment of FIG. 8A is a case of a thin content 301. In this case, the upper surface of the content 301 is connected to the ends of the first erection piece 151 and the second erection piece 152 of the first cover piece 150. Since the unit is pressed in an upright state, the contents are prevented from flowing excessively inside the box, thereby preventing the contents from being damaged during storage or transportation.

In the above-described embodiment, in order to increase the effect depending on the pressing state of the first and second erection pieces (151) (152), a support hole ( 157) [see FIG. 7a] or a support groove 158 [see FIG. 7b] may be formed, and if necessary, a bent extension 159 may be formed at the ends of the first and second erection pieces 151 and 152. ) [see FIGS. 7C and 7D] can also be formed to achieve the effect of increasing the pressing area of the contents.

The embodiment of Figure 8b is a case of packaging slightly thick contents 302. In this case, the first and second upright pieces 151 and 152 are not upright and are bent toward the inside of the first cover piece 150. It comes into contact with the upper surface of the contents 302.

Therefore, the upper surface of the contents 302 continues to be in contact with the end portions of the first and second erection pieces 151 and 152, and the first and second erection pieces 151 and 152 are placed on the upper surface of the contents due to their own elastic force. Since is slightly pressed, even in this case, it is possible to prevent the contents 302 in the assembled box 100 from flowing.

When the delivery invoice 400 on which the sender and recipient are displayed is attached to the inner part where the first cover piece 150 and the second cover piece 160 are connected to the box 100 assembled through the above process, The delivery invoice 400 also serves to seal the joints of the assembled box 100.

The embodiment of FIGS. 8C and 8D shows a case where another delivery box is placed on the upper surface of the assembled box 100 of the present invention containing the contents 301 and 302. In this case, the other delivery box is the assembled box. It is expected that the uppermost part of 100, that is, the joint between the first cover piece 150 and the second cover piece 16, will be pressed.

In the above case, the first and second erection pieces (151) and (152) of the first cover piece (150) are erected or bent at the bottom of the joint where the assembled box (100) is subjected to a concentrated load [see FIG. 8a]. Since the contents are pressed in the assembled state (see Figure 8b), even if another heavy delivery box is placed on the joint of the assembled box 100 of the present invention and a concentrated load is transmitted, it can sufficiently withstand the concentrated load. The box itself will not be crushed or damaged.

Although embodiments of the present invention have been described above with reference to the attached drawings, those skilled in the art will understand that the present invention can be implemented in other specific forms without changing the technical idea or essential features. .
