Description

Buffer material for packaging {CUSHION FOR A PACKAGING BOX}

The present invention relates to the packaging of a box, and more specifically, a packing cushioning material that can accommodate a product compactly inside a packing box and protect it from external shocks, and can easily store the items attached to the product. It is about.

When loading a product in a packaging box, an empty space may be formed between the product and another product or between the product and the packaging box after loading the product. Such empty space may be generated by the shape of the package, and may be formed by the arrangement or size difference of the packages when storing two or more packages. As such, the products accommodated in the packaging box including the empty space may move freely in the box and may be damaged by a collision. When an external shock is transmitted, the shock is delivered to the product without buffering and the product is transported. Breakage or failure may occur. In addition, the box may be recessed or crushed by an external force such as a load, thereby making it difficult to store and load the box.

Accordingly, the packaging cushioning material is used to fill an empty space in a packaging box or to protect the box and the product contained in the box by interposing the products. As a conventional packaging cushioning material, styrofoam which is a foamable material is used.

1 is a perspective view for explaining a conventional packaging cushioning material.

Referring to FIG. 1, the conventional packaging cushioning material 10 is made of expandable polystyrene, and forms a groove accommodating one surface thereof corresponding to a package 20 such as a DVD player or a video player.

Each of the two shock absorbing materials 10 covers the package 20 at both ends, and the shock absorbing material 10 and the package 20 are stored together in a box.

However, the packaging cushioning material made of expandable polystyrene is not easily stored after opening the product, and most of it is disposed of as waste, and once molded, it is impossible to be recycled and is difficult to recycle. There is a risk of contamination.

Of course, in this regard, there may be a case of constructing a cushioning material for packaging using a corrugated cardboard, etc. Conventionally, a packaging cushioning material made of corrugated cardboard is simple in structure itself and thus has a weak supporting force. It is difficult to maintain the structure of the cushioning material. Therefore, at this time, a part of the packing cushion is crushed or the entire recessed, not only does not play a role of the packing buffer but also it is difficult to maintain the structure of the packing buffer itself. In addition, since the material is made of thin corrugated cardboard, and the structure is simple, a shock absorbing effect cannot be largely obtained, the packaged product is exposed to impact when a force is applied from the outside to transmit the impact to the inside. Therefore, the product may be damaged or broken by external shock, resulting in economic loss.

In order to overcome the above problems, an object of the present invention is to maintain a stable structure even when receiving an object having a large weight, and to be manufactured by bending one of the corrugated raw material (raw material), effectively to the external impact It is to provide a buffer for packaging that can be buffered.

In addition, another object of the present invention is to provide a packaging cushioning material that allows a user to easily store the product in a packaging buffer.

In addition, another object of the present invention is to provide a packaging cushioning material that can be easily put in and out of the packaging box by the user to receive the object in the packaging buffer.

In addition, another object of the present invention is to provide a cushioning material for packaging having a storage space that can contain the secondary substrate of the object.

The bottom plate forms a bottom plate of the packaging cushioning material and is formed in a rectangular shape. The first side plate is connected to one end of the bottom plate portion, and the first top plate is connected to the first side plate. The first intermediate side plate is connected to the first top plate. The intermediate bottom plate is connected to the first intermediate side plate and the second intermediate side plate, and the second side plate is connected in parallel with the first side plate at the other end of the bottom plate portion. And the second top plate is connected to the second side plate, the second intermediate side plate is connected to the second top plate. The first indentation portion and the first indentation side plate and the first indentation that is bent inwardly connected to the first top plate through the boundary between the first top plate and the first intermediate side plate, the first incision is formed vertically And a first indentation base plate connected to the first intermediate side plate at a cutout boundary and bent inward with the first indentation side plate. A second indentation side plate and a second indentation side plate which vertically pass through a boundary between a second top plate and a second intermediate side plate, and are bent inwardly connected to the second top plate at a boundary of the second incision; And a second indentation bottom plate connected to the second intermediate side plate at a boundary of a second incision and bent inward with the second indentation side plate. The first fixed indentation portion is formed such that the first fixed incision portion vertically passes through the boundary between the first intermediate side plate and the first indentation bottom plate, and is formed by indenting the first fixed incision portion inwardly. The second fixed indentation portion is formed such that the second fixed incision portion vertically passes through the boundary between the second intermediate side plate and the second indentation bottom plate, and is formed by indenting the second fixed incision portion inwardly. The fixed support portion is formed with an incision line having an L-shaped outline on the first side plate, the second side plate, or the bottom plate portion, and is bent to the rear surface of the first and second indents at the boundary line of the incision line to form the first or second indentation. Support wealth. The fixed support portion is fixed in contact with the first or second fixed indentation portion and supports the structure of the packaging cushioning material.

The second intermediate side plate 136 is integrally connected with the second intermediate bottom plate 128b and adhered to the inner surface of the bottom plate. Therefore, a square tube-shaped structure having a part of the bottom plate 110, the second side plate 132, the second top plate 134, and the second middle side plate 136 as a side wall is formed. Therefore, the two tube-shaped cushioning material as a whole is located at a predetermined distance from each other.

In addition, the first indentation 140 includes an indent bottom plate 142 and an indentation side plate 144. The first indentation 140 forms a first cutout 140a vertically cut from the boundary of the first upper plate 124 and the first intermediate side plate 126 to form the first cutout 140a as a boundary. Bent towards. The first indentation bottom plate 110 is positioned in parallel with the bottom plate portion 110, and a portion of the first top plate 124 and an upper end portion of the first middle side plate 126 are bent inwardly, and the b-shaped shape when viewed in cross section.

The bottom plate 210 is made of corrugated cardboard, and the first side plate 222 and the second side plate 232 are connected to both sides of the bottom plate 210 via a bend line. The bottom plate 210 has a fold line 212 formed in parallel between the first middle side plate 226 and the second middle side plate 236.

The first side plate 222 is connected to one end of the bottom plate portion 210 via a bend line, and the first top plate 224 is connected to the first side plate 222 with a bend line to bend in parallel with the bottom plate portion 210. The first middle side plate 226 is connected to the first top plate 224 by a bent line, and is attached to an inner surface of the other transition base plate 210 to be a part of the bottom plate 210, the first side plate 222, A space is formed in which the first upper plate 224 and the first intermediate side plate 226 are outer walls. One edge of the middle bottom plate 228 is connected to the first middle side plate 226, and the other edge of the middle bottom plate 228 is connected to the second middle side plate 236. The middle bottom plate 228 is connected to the first middle bottom plate 228a and the second middle side plate 236 connected to the first middle side plate 226 based on the first fold line 216 formed on the bottom plate portion 210. Two intermediate bottom plates 228b. The first and second intermediate bottom plates 228a and 228b are separated from each other, adhered to and fixed to an inner surface of the bottom plate 210, and may be attached using various methods in other embodiments of the present invention. The second side plate 232 is connected to the other end of the bottom plate portion 210 via a bend line corresponding to the first side plate 222. The second top plate 234 is connected to the edge facing the bottom plate portion 210 of the edge of the second side plate 232 via a bend line and is formed parallel to the bottom plate portion 210. The second middle side plate 236 is bent vertically toward the bottom plate portion 210 by a bend line connected to a corner facing the second side plate 232 of the edge of the second top plate 234. Therefore, the edge contacting the bottom plate portion 210 is attached to the inner surface of the bottom plate portion 210, and is located side by side with the first intermediate side plate 226. The second side plate 232, the second top plate 234, and the second middle side plate 236 are based on the bottom plate portion 210 with the first side plate 222, the first top plate 224, and the first middle side plate 226. ) And corresponding to each other.

The first side plate 222 and the second side plate 232 includes a fixed support portion 220 in which an L-shaped cut line 274a is formed and bent into the space. In addition, the first side plate 222 and the second side plate 232 is cut by the L-shaped cut line 274a, the first side plate 222, the second side plate 232 or the bottom plate portion 210 The incision is concave at the acute angle. Thus, the portions supporting the first intermediate side plate 226 and the second intermediate side plate 236 are in contact with the ends of the fixed support portion 274, while the other end is spaced apart from the bottom plate portion 210. Therefore, it is located in the direction obliquely downward from the end. Therefore, even if a vertical load acting up and down acts, the fixed support part 274 does not immediately absorb the shock and the end of the fixed support part 120 descends to the bottom plate part 110 to cushion the shock, thereby increasing the buffering effect. . In addition, the first middle side plate 226 and the second middle side plate 236 are formed with a U-shaped cut line 230a from the boundary between the first and second intermediate bottom plates 242 and 252 to be bent into the space and protrude inwardly. And protruding support 230. However, in another embodiment of the present invention, the protrusion support may be formed in various shapes according to the intention of the designer.

The first indent 240 includes a first cutout 240a that is vertically cut from the boundary of the first upper plate 224 and the first intermediate side plate 226. Accordingly, the first indentation side plate 244 bent inwardly with the first cutout 240a and the first middle side plate 226 connected with the first incision 240a to be connected to the first indentation sideplate 244. And a first indent bottom plate 242 bent inward. In the embodiment of the present invention is suitable for accommodating a DVD player and the length or width of the first cutout can be made differently depending on the object to be accommodated.

The second indentation 250 includes a second cutout 250a vertically cut from the boundary of the second upper plate 234 and the second intermediate side plate 236, and has the same structure as the first indentation 240. Is formed. Therefore, the second indentation side plate 254 and the second indentation bottom plate 252 are included, and are positioned to face each other with respect to the fold line 212 of the bottom plate portion 210.

The first fixed indentation 260a has a first fixed incision 262a which vertically passes through the boundary between the first intermediate side plate 226 and the first indentation bottom plate 242, and has a first fixed incision 262a. Incision along the indentation. In addition, the second fixed indentation part 260b is also cut through the boundary between the second intermediate side plate 236 and the second indentation bottom plate 252 vertically to form the second fixed incision part 262b, so that the first indentation part is formed. Inside the 240 and the second indentation 250 is partially indented once more. The first and second fixed indents 260a and 260b are partially indented to distribute the pressing force from the outside in the curved part, thereby more firmly supporting the structures of the first and second indents 240 and 250.

In addition, the fixed support 274 serves to fix the fixed support 274 because the L-shaped fixed support 274 is bent to contact one side of the first and second fixed indents 260a and 260b. do. Therefore, the fixed indentation 260 is fixed so that the fixed support 274 is not pushed from side to side by the vertical load acting up and down to support a larger vertical load. In the embodiment of the present invention, the number of the fixed indentation 260 is limited to three, but in other embodiments of the present invention, when the user wants to support a larger force, a larger number of fixed indentations may be formed. .

The support indentation 270 is cut in the vertical direction via the boundary of the first top plate 224 and the first indentation side plate 244 to be indented into the internal space. Similarly, the boundary between the second top plate 234 and the second indentation side plate 254 is vertically cut and formed into an internal space. The shape of the support indentation 270 is a U-shaped cut line 270a is formed in the boundary direction and is indented inward. Therefore, the support indentation 270 is formed to be staggered with the direction of the force when a force is applied from the outside to increase the buffer effect while maintaining the structure. In addition, the support indentation 270 may be cut from the first indentation side plate 244 to the part of the first side plate 222 through the first top plate 224 to be indented into the internal space to maintain the structure more securely. As such, in another embodiment of the present invention, various shapes of the support indentations may be formed according to the intention of the designer, and the number of the support indentations may also be variously manufactured.

The top plate indentation 278 forms a top plate cutout 278a over the first side plate 222, the first top plate 224, and the first indentation side plate 244, and forms an interior space along the top plate cutout 278a. It is indented toward the inside. Thus, the indented first top plate 224 is positioned vertically like an H-shape between the first indentation side plate 244 and the first side plate 222. Therefore, when a force for pressing the packing buffer in the left and right occurs, the indented first top plate 224 supports the force in the internal space, it is possible to stably support the structure. In addition, the upper plate indentation 278 may have a restoring force that is slightly distorted by the force generated from the outside and then returns to its original state when the force is removed. Therefore, since the top plate indentation 278 is once more relieve the impact generated from the outside, the impact is not immediately transmitted to the product can be obtained an increased cushioning effect. In addition, the top plate indentation part 278 may be formed in the same manner in the second side plate 232, the second top plate 234, and the second indentation side plate 254.

The fixing piece 280 is spaced apart from the fixed indentation part 260 at a predetermined interval, and the first middle side plate 226 and the second middle side plate 236 are separated from the boundary between the first and second intermediate bottom plate portions 210. C-shaped incision line 280a is formed on the inner surface of the bottom face and protrudes toward the inner space at the ends of the first and second intermediate bottom plates 242 and 252 when indented along the first incision 240a. do. The fixed support 274 is positioned between the fixed piece 280 and the fixed indentation 260 to fix the left and right sides of the fixed support 274. Therefore, the fixed support 274 can effectively support the vertical load without moving from side to side.

The lower side reinforcing pieces 290 are formed at both sides of the first side plate 222 and at both sides of the second side plate 232. Therefore, the four lower side reinforcement pieces 290 have both sides of a rectangular tube shape having the bottom plate portion 210, the first side plate 222, the first top plate 224, and the first middle side plate 236 as outer walls, and The bottom plate 210, the second side plate 232, the second top plate 234, and the second intermediate side plate 236 are positioned at both sides of a square tube shape having outer walls. The first and second lower side reinforcement pieces 290 are connected to both ends of the first side plate 222 and both ends of the second side plate 232 through a bend line. Then, a portion of the bottom plate 210 is bent by being connected through a bent line to be integrally inscribed inside the first side plate 222, the second side plate 232, and the bottom plate 210. Therefore, the side of the packaging cushioning material is reinforced to prevent the structure from being crushed and to effectively buffer the force acting from the outside. The first inclined fold line 290a is formed at the same position as the boundary between the bottom plate portion 210 and the first side plate 222, and is located on the inner surfaces of the first and second lower side reinforcement pieces 290, so that the first side plate 222 and the inner surface of the bottom plate portion 210 may be in contact. And the second inclined fold line 290b is formed in the direction of about 45 degrees from the end of the first inclined fold line 290a toward the inside to fold the second inclined fold line 290b when folded to the inner surface of the bottom plate portion 210. Therefore, after being folded, it is unfolded when it comes into contact with the inner surfaces of the bottom plate part 210 and the first side plate 222. The first side plate 222, the bottom plate part 210 and the first and second lower side reinforcement pieces 290 At the same time the portion has a rhombus cut trim portion (T). Therefore, the trim part T forms the corner of the assembled packing cushion, and the outer edge of the packing cushioning material has the corner shape inclined by the trim part T. As shown in FIG. By the trim part (T), the cushioning material for packaging can be easily put into and out of the box. Even after the cushioning material is accommodated in the box, the outer corners of the packing cushioning material are partially spaced by the trim part (T). Is not passed directly to That is, the trim part T may further improve the buffering effect of the packaging cushioning material. However, in another embodiment of the present invention, the trim part T may not exist, and the shape of the trim part T may be variously manufactured according to the intention of the designer.

In addition, a portion of the upper side reinforcing piece 292 is connected to the first top plate 224 and the second top plate 234 via a bend line, and the other part of the first middle side plate 226 and the second middle side plate ( 236) and a bend line.
