Description

[Detailed description of the invention] The present invention relates to a cushioning material used for packaging electrical products such as televisions and other products, and the invention combines a cushioning material made of synthetic resin foam and a fixing device with a hooking mechanism for corrugated cardboard. It was devised to provide a product that has a general structure and can be easily packed in combination with a corrugated cardboard frame, and that can be conveniently implemented.

Next, an embodiment of the present invention will be described with reference to the drawings. 1 is a cushioning body made of a synthetic resin foam such as polystyrene foam, ethylene-styrene copolymer foam, polypropylene foam, or rigid polyurethane foam; It is formed into a thick plate shape corresponding to the bottom surface, top surface, or one side surface when the packaging material is packaged, and a receiving recess 2 into which a part of the material to be packaged fits is formed on the side that supports the material to be packaged. There is.

Reference numeral 3 denotes a fixture equipped with a latching mechanism 4 that can be latched to the cardboard and can freely lock the latched state, and is attached by being partially embedded in a predetermined position on the circumferential side of the buffer body 1. It is.

In the case of the figure, the fixture 3 consists of a latching mechanism 4 and a plate-shaped support part 5 formed in an L shape. , the L-shaped half portion 5b on the side of the latching mechanism 4 is made to protrude upwardly from the circumferential side toward the side having the support recess 2.

The part of the fixture 3 that is embedded in the buffer body 1, that is, the L-shaped half part 5 in the figure.
For a, the tip is folded back as shown in the figure, or this part is formed into a wave shape, or one or both of the upper and lower surfaces is provided with a hook-shaped turn, a collar or other protrusion, or the tip side is made thick or thick. It is provided with a means for preventing removal by forming it in a wide shape or the like.

Furthermore, when in use, the L-shaped half part 5a on the implantation side and the latching mechanism 4 are
Since the load will be concentrated on the bent part of the side L-shaped half part 5b, as shown in FIGS. 4 and 5, a U-shaped reinforcing piece 5C is integrally formed in the bent part and implanted. The side L-shaped half part 5a is extended from the center part of the reinforcing piece 5C, and the collar part 1a is formed on the circumferential side of the buffer body 1.
The bent portion can also be reinforced by embedding the reinforcing portion 5C so as to sandwich it between the reinforcing portions 5C.

In order to embed a part of the fixture 3 in the buffer body 1, when molding the buffer body 1, so-called insert molding is used, in which a separately formed fixture 3 is inserted into a mold before molding. Can be done.

Furthermore, the latching mechanism 4 in the illustrated embodiment includes latching pieces 8a and 8b connected to the upper and lower parts of the frame 7 through hinges, which can be fitted into the latching holes 6 of the corrugated board.
A collar 9 is formed on the outer periphery of the corrugated board, and by pressing one of the locking pieces 8a from the outside, the other locking piece 8b is attached.
The corrugated board can be clamped and latched between the collar 9 and the latching pieces 8a and 8b, and the latching state can be locked.

In addition to the fixing device 3 equipped with the latching mechanism 4 as described above, the fixing device 3 may be of the hinge joint type, bush joint type, rotary lock type, or other type that can be latched to corrugated cardboard and can be freely locked in the latched state. This can be implemented if a locking mechanism is provided, and of course, a means for preventing removal is provided at the part embedded in the buffer body 1.

Further, this fixture may be made of a synthetic resin having appropriate elasticity, or may be made of metal.

The cushioning material of the present invention constructed as described above is used in combination with a corrugated cardboard body frame 10 with openings on the top and bottom or both sides.For example, as shown in FIG. With the rising part of the fixture 3 protruding from the side surface tilted outward, the opening of the corrugated cardboard body frame 10 is fitted to the outside of the buffer body 1, and the fixture 3 is rotated to the outside of the body frame 10. As shown in FIG. 7, the latching mechanism 4 is latched into the latching hole 6 provided in the trunk frame 10, and the cushioning material and the trunk frame 10 are connected and fixed.

By forming a notch 11 as shown in the figure at a position corresponding to the fixture 3 at the opening end of the trunk frame 10, the lower surface of the buffer body 1 and the opening end surface of the trunk frame 10 are flush with each other, resulting in a good appearance.

In addition, when the rising part of the fixture 3 is in contact with the buffer body 1, as shown in FIG. Just fix it.

Further, when the fixture 3 is provided with a locking mechanism having a structure different from that described above, the cushioning material and the body frame 10 may be connected and fixed in a locking state according to the structure.

As described above, the present invention partially embeds a fixture equipped with a latching mechanism that can be latched onto cardboard and can freely lock the latched state at the required locations of a cushioning body made of synthetic resin foam. Since the shock absorber and fixing device are integrally constructed, it can be combined with a corrugated cardboard frame that is open at the top and bottom to serve as the bottom and lid of the package as shown in Figure 9. The bottom and top can be used as cushioning material,
In addition, if the item to be packaged is horizontally long, it can be used in combination with a corrugated cardboard frame with openings on both sides as shown in Figure 10. This allows for simple packaging without the need for.

Moreover, the cushioning material and the corrugated cardboard trunk frame can be easily and securely connected and fixed using a fixing device that is integrally attached to the cushioning body, and packing and unpacking operations are also extremely easy.

In particular, in the case of the present invention, since the part of the fixing device embedded in the buffer body is provided with means for preventing removal by means of folds, protrusions, etc., the fixing device is a buffer made of synthetic resin foam. Although it is made of non-foamed synthetic resin or metal, which is different from the body, it is strong and has excellent integration with the cushioning body, and there is no risk of it coming off even if a small amount of force is applied. Sufficiently withstands its use,
Coupled with the fact that the fixture is equipped with a latching mechanism that can be freely connected and fixed to the cardboard, it is possible to maintain an extremely stable packaging state in simple packaging as described above, without the need for tightening means such as bands. Combined with the cushioning properties unique to the synthetic resin foam of the cushioning body, it is possible to sufficiently protect the packaged product.

Therefore, the present invention is extremely suitable as a cushioning material that doubles as a lid or eave in simple packaging for domestic shipment of electrical products.
