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 buffers 10 covers the package 20 at both ends, and the buffer 10 and the package 20 are stored 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.

As described above, in the case of the conventional packaging cushioning material, synthetic resin, honeycomb, coro pad, corrugated cardboard, and the like are used as materials. Here, the synthetic resin has the advantage of easy packaging design, stability of quality, low cost and excellent buffering properties. However, there are disadvantages that harmful elements are generated during incineration, and they are not decomposed during landfill, polluting the environment, and recycling is difficult. In the case of honeycomb and coropad, the buffering property is relatively good, but there are disadvantages of low productivity and excessive logistics costs in the manufacturing process.

In addition, although there is a packaging cushioning material to be manufactured by bending the cardboard structurally, if the weight of the object is also a conventional packaging cushioning material is a large amount of impact delivered to the packaging cushioning material is large, the part of the packaging cushioning material is crushed or the entire recessed to serve as a packaging cushioning material. Not only that, but also it is difficult to maintain the structure of the packaging buffer itself. Therefore, external shocks can be transmitted to the product, resulting in economic losses.

Accordingly, one object of the present invention for solving the above-described problems of the present invention is to provide a buffer for packaging that provides a plurality of buffer space.

In addition, another object of the present invention is to provide a packaging shock absorber for structurally attaching a plurality of shock absorbing members to the portion where the load is concentrated.

In addition, another object of the present invention is to provide a packaging cushioning material for attaching a plurality of the buffer member in the direction of the bone with a large buffer effect.

In addition, another object of the present invention is to provide a packaging cushioning material having a stable structure by lowering the manufacturing cost by connecting without using an adhesive.

According to a preferred embodiment of the present invention for achieving the above object of the present invention, the packaging cushioning material includes a body and a buffer member.

The main body includes a rectangular bottom plate, a first side plate connected to an upper edge of the bottom plate and bent perpendicularly to the bottom plate, and a second side plate connected to a lower edge of the bottom plate and bent perpendicularly to the bottom plate. In the present invention, the direction of the bottom plate is set up, down, left, and right, but in another embodiment of the present invention, since the direction can be set by varying the criteria according to the intention of the designer, the present invention is not limited to the above direction. The buffer member is attached to both edges of the main body to reinforce the end of the main body. Accordingly, by separately attaching the cushioning member to the side of the main body, the packaging cushioning material can obtain a buffering effect against external load.

Conventional packaging cushioning material has a structure that cushions the external impact by rolling a plurality of layers of cardboard close to the vulnerable to impact. However, in the case of the packaging cushioning material of such a structure, but the corrugated cardboard has the effect of protecting the object by buffering the external shocks, the corrugated cardboard should be closely packed in multiple layers, and the adhesive process between the corrugated cardboard to be bonded using a process of manufacturing This is difficult. In addition, several layers of corrugated cardboard are not adequately buffered, resulting in an unnecessary overpacking effect. Therefore, the manufacturing cost of the packaging cushioning material becomes high.

However, the packaging shock absorbing material according to the present invention can obtain an increased shock absorbing effect because the shock absorbing member is mounted on the side of the main body for shock absorbing. Therefore, the structurally attached shock absorbing member buffers the external shock, so that a weak portion of the packing shock absorber may be reinforced, and thus the shock absorber may absorb and cushion a large amount of shock. At this time, since the buffer member forms a buffer space therein, a portion of the buffer member may collapse into the buffer space due to external shock, thereby absorbing a large amount of shock, and further enhancing the buffering effect of the packing buffer. At this time, since the impact amount is proportional to the weight, the packaging shock absorbing material according to the present invention having a large cushioning effect can be used in electronic products such as a DVD player.

In addition, according to another preferred embodiment of the present invention for achieving the above object of the present invention, the packaging cushioning material includes a body and a buffer member.

The main body includes a rectangular bottom plate, a first side plate connected to an upper edge of the bottom plate and bent perpendicularly to the bottom plate, and a second side plate connected to a lower edge of the bottom plate and bent perpendicularly to the bottom plate. At this time, the material of the main body is made of corrugated cardboard, and the bottom plate, the first side plate and the second side plate has a bone direction toward the left and right of the bottom plate. In the present invention, the direction of the bottom plate is set up, down, left, and right, but in another embodiment, the present invention is not limited to the above direction because the direction may be set according to a designer's intention. And the material of the buffer member is similarly made of cardboard, and the buffer member includes a first buffer side plate, a buffer top plate, a second buffer side plate and a buffer bottom plate. The first buffer side plate is formed orthogonal to the first side plate and the second side plate to form one side wall of the body, and the buffer top plate is connected to the corners of the first buffer side plate and covers the tops of the first side plate and the second side plate. The second buffer side plate is connected to one edge of the buffer top plate and abuts the end of the body, and the buffer bottom plate is connected to one edge of the second buffer side plate and fixed to the lower portion of the first and second side plates. In addition, the buffer member has a bone direction perpendicular to the bone direction of the main body, thereby enhancing the cushioning property among the cardboard properties.

In the present invention, the bone direction refers to the direction of the flute (corrugated corrugated cardboard), and in the case of the packaging cushioning material according to the present embodiment, the main body and the cushioning member are attached with different bone directions, and are always applied to externally applied loads. It is attached to be in a vertical direction. Experimental data indicate that the basic physical properties are the highest when the bone direction is the same as the load. Therefore, the corrugated paper in the direction is easily crushed by the external impact or has the effect of supporting the structure, but the shock absorbing effect is lowered because the external shock is transmitted directly to the object. However, the corrugated paper in the direction perpendicular to the load has the lowest compressive strength, so that the corrugated paper is easily distorted by external impacts. However, since the external shock is absorbed by the corrugated cardboard itself, the cushioning effect is higher than that of the corrugated cardboard in parallel. Relatively high. As such, the packaging cushioning material according to the present invention has a valley in the direction perpendicular to the external load, and thus has a high effect of buffering the load, and thus can be used for a heavy object such as a DVD and an electronic device. Therefore, the packaging cushioning material according to the present embodiment may be used as a cushioning product in various fields.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, but the present invention is not limited or limited by the embodiments.

Example 1

Figure 2 is a perspective view for explaining a packaging cushioning material according to a first embodiment of the present invention, Figure 3 is an exploded view of the body of the packaging buffer according to the first embodiment, Figure 4 is a packaging buffer according to the first embodiment It is an expanded view of a buffer member.

2 to 4, the packaging cushioning material 100 includes a main body 110 and a buffer member 130. The packaging cushioning material 100 according to the present embodiment is designed to accommodate a DVD player as an object, but in another embodiment of the present invention, it can be applied to various products according to the designer's intention.

The main body 110 forms an accommodation space for accommodating a DVD player, and includes a bottom plate 112, a first side plate 114, a second side plate 116, a first reinforcement plate 118, and a second reinforcement plate ( 120). Since the bottom plate 112 has a length corresponding to the side of the DVD player, it is formed in a rectangular shape. However, in another embodiment of the present invention can be formed in the shape of various objects according to the intention of the designer. Accordingly, the bottom plate 112 forms four corners at the top, bottom, left, and right sides, and in this embodiment, the bottom plate 112 may be set to an upper edge, a lower edge, a left edge, and a right edge of the bottom plate 112 in correspondence to the top, bottom, left, and right sides of the drawing. In an embodiment, it may be set differently according to a designer's intention. The bottom plate 112 may have an incision line corresponding to the protruding shape to accommodate the protruding portion of the object. The bottom plate 112 is made of corrugated cardboard, and in the present invention, the body 110 and the shock absorbing member 130 may be manufactured using corrugated cardboard.

The first side plate 114 is connected to the upper edge of the body 110 via a bend line, and is bent perpendicularly to the bottom plate 112 to form one side wall. The second side plate 116 is connected to the lower edge of the main body 110 via a bend line to be bent perpendicularly to the bottom plate 112 to form sidewalls corresponding to the first side plate 114. Accordingly, the bottom plate 112, the first side plate 114, and the second side plate 116 provide an accommodation space for accommodating one side of the object, and accommodate the object in the accommodation space to protect the object from external impact. Can be. The first side plate 114 is connected to the edge facing the upper edge of the bottom plate 112 by the first reinforcement plate 118 and the bend line, and the first reinforcement plate 118 is the first auxiliary to the other edge The reinforcing plate 118a is connected to the bend line. In this case, the first reinforcement plate 118 and the first auxiliary reinforcement plate 118a are formed in the same size, and the height is relatively larger than that of the first side plate 114. In addition, like the first reinforcement plate 118, the second reinforcement plate 120 is connected to the second auxiliary reinforcement plate 120a through a bend line, and the second auxiliary reinforcement plate 120a has the same size. The height of the second side plate 116 is greater than that of the second side plate 116. Accordingly, the first reinforcement plate 118 and the second reinforcement plate 120 are bent in directions opposite to the direction in which the first side plate 114 and the second side plate 116 are bent, respectively, and the first auxiliary reinforcement plate 118a. ) And the second auxiliary reinforcing plate (120a) is bent in a direction in contact with the inner surface of the first reinforcing plate 118 and the second reinforcing plate (120), respectively. The main body 110 bent in this way is a bottom plate to accommodate the side of the object by the height difference between the first reinforcement plate 118 and the second reinforcement plate 120 and the first side plate 114 and the second side plate 116. A buffer space is formed at the bottom of 112. Therefore, since the external shock is not directly transmitted to the object by the buffer space, the shock absorbing effect can be enhanced.

The buffer member 130 is attached to both sides of the main body 110. The buffer member 130 includes a first buffer side plate 132, a buffer upper plate 134, a second buffer side plate 136, and a buffer bottom plate 138. Since the first buffer side plate 132 is symmetrically formed with respect to the bend line, the first buffer side plate 132 is doubled when folded along the bend line. This is because the first buffer side plate 132 is in close contact with the side of the object and directly transmits an external shock to the object, and thus it is necessary to have a multi-structure in order to effectively buffer the object. However, in another embodiment of the present invention may have a structure of two or more layers according to the intention of the designer. The inner surface of the first shock absorbing side plate 132 is provided with a binding slit groove 142 cut in correspondence to the binding inserting piece 144, and is inserted in a direction perpendicular to the first side plate 114 and the second side plate 116. The first cutout 148 is formed to be cut in correspondence with the first side plate 114 and the second side plate 116. In addition, the first side plate 114 and the second side plate 116 correspondingly have a second cutout 122 formed therein so that the first cutout 148 and the second cutout 122 are coupled to each other to cushion the member. 130 is stably fixed to the side of the body (110). The side support 146 is connected to one corner of the first buffer side plate 132 via a bend line. The side support 146 serves to partially fill the buffer space formed inside the first buffer member 130 when the first buffer member 130 is attached to the main body 110. Therefore, since the structure of the 1st buffer side plate 132 is prevented from collapsing easily by an external shock, the structure can be maintained even in several drop tests.

The buffer top plate 134 is connected to one edge of the first buffer side plate 132 and covers the upper portions of the first side plate 114 and the second side plate 116. At this time, the buffer upper plate 134 covers the upper portion from the second cutout 122 to the ends of the first side plate 114 and the second side plate 116. The second buffer side plate 136 is connected to one edge of the buffer upper plate 134 and is in close contact with end edges of the first side plate 114 and the second side plate 116. In addition, a buffer bottom plate 138 is connected to one corner of the second buffer side plate 136 via a bend line, and a bottom plate inserting portion 140 is connected to one corner of the buffer bottom plate via a bend line. The bottom plate inserter 140 is inserted into the bottom plate slit groove 124 formed under the first side plate 114 and the second side plate 116 to fix the lower end of the buffer member 130 to the main body 110. Thus, the shock absorbing member 130 has a structure that completely surrounds the side of the main body 110, thereby cushioning the external shock and maintaining a stable structure. Therefore, the packaging cushioning material according to the present embodiment prevents the structure from collapsing due to an external impact to concentrate the force on the collapsed portion of the packaging cushioning material. And 10 impact tests and free fall tests performed on 6 sides. Dotted lines and dashed-dotted lines in FIGS. 3 and 4 indicate opposite directions in which the lines are bent.

Figure 5 is a partial perspective view for explaining that the shock absorbing member of the packing cushioning material according to the first embodiment of the present invention, Figure 6 is a partial perspective view for explaining the inside of the shock absorbing member of the packing cushioning material according to the first embodiment to be.

5 and 6, the first buffer side plate 132 is positioned at a position corresponding to the second cutout 122 of the first side plate 114 and the second side plate 116. After placing it, insert it face down. The first buffer side plate 132 is orthogonally fixed to the ends of the first side plate 114 and the second side plate 116 at predetermined intervals. In this case, the predetermined interval may be set in consideration of the weight of the object. After the first buffer side plate 132 is inserted into the first side plate 114 and the second side plate 116, the side support 146 connected to the first buffer side plate 132 via a bend line is 자 -shaped. Bend into a shape to fill the buffer space of the buffer member. At this time, the side support 146 has a bone direction parallel to the force acting from the outside, so that the structure of the buffer member 130 is supported so as not to collapse.

Then, when the buffer upper plate 134 connected to the other end of the first buffer side plate 132 is bent in a direction covering the first side plate 114 and the second side plate 116 (ⓐ), the buffer member 130 is While covering along the side of the main body 110 can be maintained without a stable adhesive structure. Therefore, the attachment of the buffer member 130 is structurally solved without using an adhesive to reduce the manufacturing cost.

FIG. 7 is a front view illustrating a buffer space of the packing buffer according to the first embodiment of the present invention, and FIG. 8 is a cross-sectional view in one direction for describing the buffer space of the packing buffer according to the first embodiment, and FIG. 9. Is a cross-sectional view in two directions for explaining the buffer space of the packaging cushioning material according to the first embodiment.

Referring to FIG. 7, since the buffer members 130 attached to both sides of the main body 110 are formed to have the same length, two buffer spaces are formed between the main body 110 having a short left and right length and the packing box. (A, Y). In addition, the four corners of the buffer member 130 is formed with an inclined surface to provide a buffer space in the corner of the packaging box (C). Therefore, the packaging box primarily buffers the load (arrow) acting from the outside, the buffer spaces (A, B, C) secondaryly buffer the load, and the packaging buffer again buffers the load, thus providing a buffering effect. Is maximized.

Referring to FIG. 8, since the first reinforcing plate 118 and the second reinforcing plate 120 are in close contact with the packing box, a predetermined buffer space is formed in the bottom plate 112 and the packing box (D). The buffer space (D) can also increase the buffering effect by absorbing external forces in the buffer space when an external force is applied.

Referring to FIG. 9, a buffer space is similarly provided inside the buffer member 130 (E, F). The internal spaces E and F buffer external forces (arrows). Further, the second buffer side plate 136 and the buffer bottom plate 138 are connected to each other by the inclined surface 138a, and the buffer space is formed at the corner of the packing box by the inclined surface 138a (Ｇ). . Therefore, even if a large shock occurs in the object accommodated in the packaging cushioning material absorbs and absorbs some of the force by the plurality of buffering spaces provided in the packaging buffer and the packaging box, the object can be stably protected.

The cushioning material for packaging according to the present embodiment partially covers the side of the main body 110 and is structurally attached to the cushioning member 130 to increase the buffering effect and thus accommodate a large weight object. In addition, since the adhesive is not used when the packaging cushioning material is manufactured, the manufacturing cost can be lowered, and the advantages of corrugated cardboard can be obtained, such as folding and storing or less storage space of empty boxes, and reducing environmental pollution.

Example 2

FIG. 10 is a perspective view of a packing buffer according to a second embodiment of the present invention, and FIG. 11 is a partial perspective view for explaining a bone direction of the packing buffer according to the second embodiment.

10 and 11, the packaging shock absorbing material 200 includes a main body 210 and a shock absorbing member 230.

The main body 210 includes a bottom plate 212, a first side plate 214, a second side plate 216, a first reinforcement plate 218, and a second reinforcement plate 220. The bottom plate 212 may be formed in the shape of the side of the object, and an incision line corresponding to the protruding shape may be formed to accommodate the protruding portion of the object. The bottom plate 212 is made of corrugated cardboard, and in the present invention, the body 210 and the shock absorbing member 230 may be manufactured using corrugated cardboard. Since the bottom plate 212 has a valley direction toward the left and right edges, the bottom plate 212 is easily bent by an external force acting perpendicular to the bottom plate 212. Therefore, the cardboard absorbs most of the impact acting perpendicular to the bottom plate 212 to protect the object, the shock acting toward the upper and lower edges of the bottom plate 212 serves to support the structure of the packaging cushioning material.

The first side plate 214 is connected to the upper edge of the body 210 via a bend line, is bent perpendicularly to the bottom plate 212 to form one side wall, the second side plate 216 is the body 210 It is connected to the lower edge of the bent line through the bend perpendicular to the bottom plate 212, and forms a side wall corresponding to the first side plate (214) (ⓑ). The first reinforcing plate 218 is connected to the corner of the first side plate 214 facing the upper edge of the bottom plate 212 by a bend line, and the second side plate 216 is formed at the lower edge of the bottom plate 212. 2 is connected by the reinforcing plate 220 and the bending line. The first side plate 214 and the second side plate 216 have a valley direction toward left and right edges and are bent perpendicular to the bottom plate 212. Accordingly, the first and second side plates 214 and 216 are formed in a valley direction perpendicular to the direction of the pressure applied from the outside to absorb the pressure to increase the buffering effect.

The buffer member 230 is attached to both sides of the main body 210 and includes a first buffer side plate 232, a buffer top plate 234, a second buffer side plate 236, and a buffer bottom plate 238. The first buffer side plate 232 is formed in two layers, and is inserted into the first and second side plates 214 and 216 so as to be orthogonally spaced apart from each other by a predetermined interval. In this case, a first cutout 248 is formed to be cut in correspondence with the first side plate 214 and the second side plate 216 to be inserted in a direction orthogonal to the first side plate 214 and the second side plate 216. do. In addition, the first buffer side plate 232 has a valley direction toward a direction perpendicular to the valley direction of the main body 210. Therefore, the first buffer side plate 232 serves to buffer the external pressure, the body 210 serves to support the structure against the external pressure at the side. As a result, it is difficult to maintain the structure because the strength drops sharply when subjected to multiple impacts by the characteristics of the corrugated cardboard, and to maintain the structure, all of the shortcomings of the shock absorbing effect is reduced since the external shock is directly transmitted to the object. Therefore, since the structure of the 1st buffer side plate 232 is prevented from collapsing easily by an external shock, the structure can be maintained even in several drop tests. In addition, since the buffer top plate 234, the second buffer side plate 236 and the buffer bottom plate 238 are substantially the same as the first embodiment, and the functions and effects of the components are substantially the same in the description of the present embodiment, Reference may be made to the description and drawings of the previous embodiment, and repeated content may be omitted.

12 is a side view for explaining a buffer member according to a second embodiment of the present invention.

Referring to FIG. 12, the bone height of the buffer member 230 may be higher than the bone height of the main body 210. The goal height of the cardboard means the distance between the lowest position and the highest position in the wave of the goal (ⓒ). Therefore, the higher the height of the bone to form a relatively more buffer space between the bones, the higher the height of the corrugated cardboard can have a relatively high buffering effect against external pressure. The reason why the buffer member 230 uses the corrugated cardboard having a relatively higher bone height than the main body 210 in the present embodiment is that the contact area with the object to be accommodated is relatively narrower in the buffer member 230 than the main body 210. This is because the area for absorbing the force of N is also relatively narrowed, so that the force is concentrated more in that part. As such, in another embodiment of the present invention, it can be designed to use a corrugated cardboard having a high bone height in the portion where the force is concentrated according to the intention of the designer.

Therefore, the cushioning material for packaging according to the present embodiment is designed in the direction of the bone perpendicular to the external pressure, using a corrugated cardboard with a high bone height in the portion where the pressure is concentrated to maximize the buffering effect to accommodate a large weight object Suitable. In addition, the structure of the packaging cushioning material can be maintained without collapse even in the multiple impact, it is economical to lower the manufacturing cost by structurally attaching without using an adhesive.

Can be.

The first reinforcement plate 318 is connected to one edge of the first side plate 314, and at the end of the first reinforcement plate 318, a first protrusion 318a protruding toward the bottom of the bottom plate 310 is predetermined. The two are spaced apart. However, in another embodiment of the present invention, the number of protrusions may be variously set according to the intention of the designer. In addition, a first adhesive piece 318b adhered to the lower part of the first reinforcing plate 318 between the first protrusions 318a is connected to the first reinforcing plate 318 via a bend line.
