Problems solved by technology

[0005] However, the above-mentioned three-dimensional cushioning material cannot absorb all the shocks caused by falling or the like only by the air passing through the bag when putting fragile objects to be protected such as bottles or relatively heavy objects to be protected such as electrical appliances into the space. Sometimes the capsule ruptures, or the air in the capsule moves, and the direct impact is transmitted to the object to be protected, which will damage the object to be protected

[0035] The material of the three-dimensional cushioning material 4 of the present invention adopts soft resin films such as polyethylene without air permeability, and adopts it to make the plane cushioning plate 1 at first. In this embodiment, two substantially rectangular polyethylene films having an upper short side 1a, a lower short side 1b, and a left long side 1c and a right long side 1d in a positional relationship orthogonal to each short side 1a, 1b are used. (same shape) (refer to figure 2 ). The films are laminated, and the films 11 are formed in multiple places by thermocompression bonding or the like on a part of the films, and a plurality of independent bladders 12 and air introduction passages 13 communicated with the bladders 12 are separated and formed, thereby forming such as figure 2 The plane buffer material 1 shown.

[0036] In this embodiment, two films are used to make the plane cushioning material 1 , but one film can be folded to make the same thing, ...

Abstract

A cubiform cushioning medium 4 comprises a planar cushioning medium 1 with a plurality of cells 12 formed by partially bonding non-breathable flexible resin sheets and the cells 12 which air is encapsulated thereinside, and the planar cushioning medium 1 is folded and bonded partially to complete an opening A to be protected for containing. The cubiform cushioning medium 4 thus has lateral cushioning faces 31, 34 disposed at the side of the opening 42 and an bottom cushioning portion 35 disposed at the bottom of the opening 42 by bending the planar cushioning medium 1 at the bottom end of the lateral cushioning mediums 31, 34 so that the end cushioning medium 35 is folded upward to the top of the lateral cushioning mediums 31, 34.

Description

technical field [0001] The present invention relates to a three-dimensional cushioning material for packaging to prevent damage to protected objects such as bottles and electric appliances. Background technique [0002] Conventionally, an air-filled cushioning material in which resin films are laminated to form an air-filled portion between the films has been widely used. This enables the object to be protected to be protected from external shocks by bringing the air filling portion into contact with part or all of the object to be protected. [0003] As an example of the above-mentioned air-filled cushioning material, it is proposed in Japanese Patent Office Publication No. 6-35973. It is formed by bonding air-tight plastic films to form air-filled bags, and making the plastic films that form the bags into envelopes, thereby forming a three-dimensional buffer with a space for containing objects to be protected inside. material. [0004] In addition, the bladders are conn...
