Description

  The present invention relates to a buffer structure that can be multiplexed and combined, and in particular, a buffer that covers a protected product so as to create a role such as resistance to pressure and dropping and impact between the packaging box and the protected product. The present invention refers to a structure, and relates to a buffer structure that can be multiplexed and combined that can be applied to electric appliances, computers, various screens, electronic products, mechanical products, and fragile items.

  For transporting or transporting protected products such as electrical appliances, computers, various screens, electronic products, mechanical products, and fragile items, all of them have a buffering effect between the packaging box and the protected product. It is necessary to cover the outside of the protected product with a cushioning material. This achieves the effect of protecting these protected products during the transport or transport process.

The traditional cushioning material is a styrofoam, but it cannot protect the environment, has a large volume, and has a large volume, so it takes container space and increases transportation costs.
Furthermore, there is a drawback that the roles such as resistance to pressure and resistance to dropping and impact are all insufficient.

  As shown in FIG. 1, a conventional cushioning material 900 has a cushioning body 9 molded by paper pulp molding (pulp mold). The buffer body 9 is U-shaped and has a hollow body 91 that is also U-shaped and four arc-shaped side ends 92, and the hollow body 91 and the four arc-shaped side ends 92 Play a buffer role.

However, these conventional cushioning materials 900 have the following drawbacks.
(1) Roles such as resistance to pressure and resistance to dropping and impact are still insufficient.
(2) Since it is necessary to produce a dedicated mold and a dedicated cushioning material for various sizes of protected products, it is obvious that the manufacturing cost is high and resources are wasted.
(3) Since the cushioning material 900 is produced by paper pulp molding (pulp mold), there is a disadvantage that off-flavors are generated under high temperature and high humidity (sealed in a container and for shipping).
(4) It cannot be applied to maritime transportation because it cannot prevent humidity and cannot withstand high temperatures.
(5) There is a defect that the pressure strength is insufficient and the deposition height after packaging cannot be deposited even higher.

  Therefore, it is a problem to be solved by the present invention how to design the present invention that can improve the above-mentioned drawbacks of the conventional cushioning material.

  The purpose of the present invention is to create a role such as favorable pressure resistance between the packaging box and the protected product, resistance to dropping and impact, etc. due to special structural design and multi-layer design, high pressure strength, Achieves the effect of increasing the stacking height after packaging, and can be applied to protected products of various sizes by the stretchable structure design, reducing the cost and not wasting resources It is to provide a buffer structure that can be multiplexed and combined.

  The next object of the present invention is to have a role such as preferable resistance to pressure and resistance to dropping and impact, so that the thickness of the buffer structure does not need to be increased. It is an object of the present invention to provide a buffer structure that can be combined with each other and can be manufactured in the same mold, and can achieve the effect of lowering costs and not wasting resources.

  Another object of the present invention is to provide a buffer structure that can be combined with each other in such a manner that the applicability of these buffer structures can be broadened by fixing at least one stopper in the cover groove of the buffer structure. Is to provide.

  Another object of the present invention is that the paper material for producing the buffer structure is a base paper (also referred to as a processed base paper, such as a cardboard base paper), and is not a conventional paper pulp molding (pulp mold) method. Therefore, it has the effect of preventing off-flavors, preventing humidity, being resistant to high temperatures, and being applicable to shipping, and also has a small volume, does not take up container space, lowers transportation costs, and meets environmental protection requirements. It is another object of the present invention to provide a buffer structure that can be multiplexed and combined with the same effect.

  In order to achieve the above-described object, a buffer structure for multiplexing and combining provided by the present invention includes at least two main bodies and a pair of tip head portions. The two main bodies are made of paper, and each of the long bar-shaped and U-shaped main bodies has a hollow body formed in accordance with its outer shape. Extending through both ends of the main body, one of the main bodies is movably inserted into the hollow body of the other main body to form a telescopic rod, and the pair of tip head portions are also made of paper, The U-shaped tip head portion has a hollow body formed according to its outer shape, and each hollow body passes through both ends of each tip head portion, and the hollow body of each tip head portion. Inside, at least a reinforcing material made of paper material is accommodated, and each of the pair of tip head portions can be movably inserted into both ends of the telescopic rod in accordance with the hollow body of each main body.

  Therefore, a role such as favorable pressure resistance between the packaging box and the protected product, resistance to dropping and impact, and the like can be applied to protected products of various sizes due to the stretchable structure design. The pressure strength is high, the deposition height after packaging is increased, and the effect of reducing costs and not wasting resources can be achieved.

  As shown in FIG. 6, the buffer structure 100 further includes a stopper 3 made of at least a paper material (for example, cardboard paper), and the stopper 3 is fixed in the concave groove 15 of the one main body 1. That is, the buffer structure 100 fixed to the cover groove 16 (as shown in FIG. 6) of the buffer structure 100 is formed by being movably inserted between the three main bodies 1. As shown in FIG. 7, the stopper 3 can be applied to a protected product 500 that needs to accommodate a small accessory (not shown) at the same time, that is, an upper stage having a larger space between a pair of buffer structures 100. Covers the protected product 500, and the protected product 500 is stopped by the stopper 3 and is not easily loosened. The lower part of the smaller space between the pair of cushioning structures 100 is divided into left and right parts of the protected product 500. As shown in the figure, the protected product 500 is a notebook, and the two small accessories are a power line and a transformer of the notebook, respectively. 100 has the effect of wider applicability due to the stopper 3 (applicable to protected products having various different sizes and different small accessory parts), and thus accommodates the small accessory parts simultaneously. Kill as to become. Alternatively, when the length of the protected product 500 is shorter than any one of the main bodies 1 (not shown), the stopper 3 is provided in the concave groove 15 of the single main body 1 so that the protected product 500 is difficult to loosen. It may be fixed.

  As shown in FIG. 8, at least one stopper 3 can be fixed also in the cover groove 16 of the buffer structure 100. As shown in the figure, two stoppers 3 are fixed, and the buffer structure 100 is divided into three stages. The step having the larger space covers the protected product 500, and the other steps having the smaller space can accommodate four small accessory parts.

  As shown in FIG. 9, when the weight of the protected product 500 is heavy, the tip head portion 2 is provided at one end of the buffer structure 100 in order to avoid damage to the bottom of the heavy protected product 500 due to gravity. However, the other end does not have a tip head portion, and a long bar-shaped stopper 3 is fixed in the cover groove 16 adjacent to the other end, and the heavy product to be protected 500 is placed underneath.

  The stopper 3 may be configured in any manner, and the embodiment shown in the figure includes a pair of U-shaped materials 31 and 32 both made of paper, and the pair of U-shaped materials 31, 32 forms a rectangular body facing each other, and each of the U-shaped members 31 and 32 is provided with a pressure-resistant pattern (not shown).

  The characteristics of the buffer structure that can be combined and combined according to the present invention is that a special U-shaped and pressure-resistant pattern 14, 24, etc. is added, and a multilayer design is further added between the packaging box and the protected product. It has a good pressure resistance, resistance to drop and impact, etc., achieves the effect of high pressure strength and higher deposition height after packaging, and the multi-layer design here Is a place where the two main bodies 1 overlap each other (as in c of FIG. 4), a reinforcing material 25 provided in each tip head portion 2, or a reinforcing material provided in each main body 1 ( In addition, it can be applied to protected products 500 of various sizes due to the stretchable structural design of the plurality of main bodies 1 that are inserted through each other, thereby reducing costs and resources. The effect which is not wasted can be achieved. Since the buffer structure 100 has a role such as a preferable pressure resistance and resistance to dropping and impact, it is not necessary to increase the thickness of the buffer structure 100, and the main body 1, the tip head portion 2 and the stopper are not required. All three can be manufactured with the same mold, and can achieve the effect of lowering costs and not wasting resources. Furthermore, by fixing at least one stopper 3 in the covering groove 16 of the buffer structure 100, the applicability of these buffer structures 100 (applied to protected products having various different sizes and different small accessory parts, respectively) Can be made wider, and thus various small accessories can be accommodated simultaneously. By fixing the long bar-shaped stopper 3 to one end of the cover groove 16 of the buffer structure 100, gravity from the heavy protected product 500 (the direction of gravity is parallel to the longitudinal direction of the long bar-shaped stopper 3). In addition, for example, a larger external force (external force direction is parallel to the longitudinal direction of the long bar-shaped stopper 3) such as vibration, impact, or rocking can be supported. It is possible to support directional gravity or external force, which is advantageous for protecting heavy products to be protected, and thus the volume of a plurality of packaging boxes can be increased. The paper material for producing the buffer structure 100 is a base paper (also referred to as a base paper or a processed base paper, for example, a cardboard base paper), and is not a conventional paper pulp molding (pulp mold) method. It has such effects as prevention, high temperature resistance, and application to marine transportation, and further has an effect that the volume is small, container space is not required, transportation cost is reduced, and environmental protection requirements are met. The main body 1 and the front head portion 2 have the hollow bodies 10 and 20, respectively, so that they have an allowable margin for vibration and swinging. In other words, external force is applied to the outer wall of either the main body 1 or the front head portion 2. In this case, only the outer wall is affected by the external force due to the presence of the hollow bodies 10 and 20, but the inner wall is not affected. Therefore, the protected product 500 that is in contact with only the inner wall is free from vibration and oscillation due to the external force. Thus, the protected product 500 is not worn by friction.

  The above-described configuration is merely a preferred embodiment of the present invention and does not limit the features of the present invention. Any expert having ordinary knowledge in the field can appropriately It goes without saying that transformations and modifications can be carried out, but those implementations should be delivered within the scope of the claimed invention.
