Description

Cushioning material for packaging box with shape maintaining function}

The present invention relates to a shock absorbing material for a packaging box having a shape-keeping function, and more particularly, to provide a shape-maintaining elastic buffer means and an elastic buffer guide means in the case body to be supported by the mounting of the object by the weight of the object The shape of the main body is prevented from being deformed, and the object moves along the object when the object is moved, so that the support can be stably supported and the shock absorbing material for the packaging box having a shape maintaining function that can block the transmission of external shocks. It is about.

In general, products that are sensitive to external shocks, such as fruits or glassware, are stored in boxes and delivered. At this time, the conventional box used is rectangular and is formed such that the inner space has only one space. Therefore, in order for each item to be stored, it is essential to wrap it with a styrofoam or other cushioning material which can mitigate the shock to prevent damage caused by shock or vibration during transportation.

Therefore, in order to avoid direct contact with external shocks, the packaging of glass products or fruits uses buffers using styrofoam, air caps, and papers on the exterior of the product. It is not fully protected from external shock. In addition, in the prior art, additional costs are incurred by materials entering the buffer packaging material, processing techniques, and work processes required therein, and a customer receiving the corresponding box has a problem in that a large amount of garbage is generated because the buffer material is peeled off and used.

In order to solve this problem, a shock absorber has been developed that can be transported and stored in a state in which the object is not in contact with the box and the cushioning material, which is embedded in the packaging box. However, the shock absorbing material is mounted on both ends of the object to be locked, but there is a problem in that both side walls of the shock absorbing material are deformed inward due to the weight of the object, thereby causing the problem that the object is rubbed or pressed against the bottom of the shock absorbing material.

The foregoing invention refers to the background of the art to which the present invention pertains, and does not mean the prior art.

A support frame 51, a lower support frame 52 made of a synthetic resin or metal material that is fitted and wrapped around the case body 20 so as to be disposed below the upper support frame 51, and the lower support Elastic coil springs 53 having a lower end fusion-fixed to the upper part of the frame 52 and an upper end fusion-fixed to the lower part of the upper support frame 51, and a curved elastic support installed on the upper support frame 51. Consists of a unit 54, it is possible to prevent the shape of the case body 20 is deformed by the upper support frame 51 and the lower support frame 52, the elastic coil spring 53 is The upper support frame 51 and the lower edge And connecting the frame 52 is supported by the upper support frame 51, it becomes possible to buffer an external impact due to the elastic supporting unit 54 will be described later, it is possible to support the object (100).

At this time, the upper support frame 51 is formed integrally by connecting the side support bar 511 and the side support bar 511 disposed on the outer surface of the side panels 23 of the case body and the It consists of a connection support bar 512 disposed on the front panel and the rear panel 22, the connection support bar 512 surrounds the slit hole 41 formed in the front panel and the rear panel 22. Reinforcing parts of the bent frame structure is opened while being arranged is further formed, the lower portion of the reinforcing portion is the elastic support unit 54 is disposed, the object that is disposed outside through the engaging hole (42) 100).

The elastic support unit 54 is formed of a curved panel made of a synthetic resin material having elasticity, and fused and fixed to the reinforcing portion as shown in the drawing, together with the elastic coil spring 53 to the outside from the casing body The object 100 to be exposed is supported by elasticity and buffers an external shock from being transmitted to the object 100.

The front panel and the rear panel 22 are pulled into the casing body and tilted by the weight of the case 100 by the case body and the lower case, thereby deforming the object 100 and the casing body. It can be prevented from being pressed against the floor.

The case main body 20 further supports the mounted object 100 and guides the moving object 100 when the object 100 is moved to prevent separation from the case main body 20. Prepared.

The elastic buffer sliding guide means 60 is inserted into the coupling holes 61 and the case body 20 of the through structure is formed while maintaining a predetermined interval on the outer surface of the case body 20, the coupling Inner support frame 62 made of synthetic resin or metal material having integrally formed connecting bars 621 on the outer surface so as to be fused and connected to lower support frame 52 through the ball, and fixing bars of the inner support frame 62. The support bar 63 made of a synthetic resin material or a metal material is connected to the inner surface of the fixing bar is fixed to the end of the fusion or screw fastening, maintaining a predetermined interval inside the inner support frame 62, The lower end portion is fused and fixed to the upper portion of the support bar 63, and the support coil springs 64 supporting the object 100 by elasticity and the support coil springs 64 connect the support coil springs. At the top of the 64 Is fused and fixed to the curved shock buffer cap 65, the guide rollers 66 are formed to be exposed to the outside on the inner surface of the impact buffer cap 65 and the guide rollers 66 It is fitted to the shock buffer cap 65 to be guided, the curved support transfer cap 67 for supporting the object 100 mounted on the case body 20, and the upper end of the impact buffer cap 65 A stopper 68 having a stopper portion 681 formed to prevent the support transfer cap 67 from being separated from the impact buffer cap 65, and a buffer space formed in the support bar 63; 69).

At this time, it is preferable to further form a curved guide guide groove so that a portion of the guide roller 66 is guided by the bottom of the support transfer cap (67).

In addition, the upper surface of the support transfer cap 67, it is preferable to further adhere the elastic pads formed with friction protrusions made of a synthetic resin material having an elasticity on the upper surface to support the object 100 by elasticity.

The buffer space 69 can cushion the noise or the impact, and reduce the weight of the support bar 63.

The support transfer cap 67 is moved by the guide roller 66 to support the object 100 by the elasticity of the support coil spring 64, so that the object 100 during the transfer of the mounting portion ( 40 is prevented from being separated, it is possible to prevent the object 100 is moved to collide or rub against the bottom or inner surface of the casing body.
