example 1
[0037]FIG. 1 are developed views of constituent members of a packing device for an article to be delivered by home delivery service according to the present invention. The packing device for an article to be delivered by home delivery service in this example is formed by combining and laminating a mat 1 and an outer layer sheet 2 integrally. A valve 6 is attached to the mat 1 as shown in FIG. 1(a). The mat 1 is formed by filling cushioning bodies 4 in an airtight bag formed by overlapping a front surface sheet 1a and a rear surface sheet 1b that are airtight and rectangular and sealing the peripheral edges thereof, and the valve 6 is for evacuating air from the inside of the mat 1 or taking the outside air into the inside of the mat, and is attached to a part of the mat 1.
[0038]In this example, the outer layer sheet 2 is merely a cover covering a surface of the mat 1 as shown in FIG. 1(b), and in a part of the sheet surface, a small hole H which the valve 6 attached to the mat faces...
example 2
[0060]In this example, as shown in FIG. 11, the sheet surface of the mat 1 is bonded (heat-welded) in a range of a fixed area, and on a specific portion of the mat 1, a non-cushioning portion 40 with no cushioning bodies filled is locally formed. In order to obtain the cushioning effect uniformly on the entire surface of the mat 1, it is necessary to fill the cushioning bodies 4 uniformly in the mat 1, however, in the case where beads are used as the cushioning bodies 4, if beads are filled uniformly in the mat, filling of beads may be biased, and the thickness of the mat may partially become excessively thick.
[0061]In order to eliminate these problems, it is effective that the non-cushioning portion 40 without cushioning bodies are formed by properly heat-welding the front surface sheet and the rear surface sheet of the mat 1. The non-cushioning portion 40 is formed by bonding upper and lower sheet surfaces of the mat of a specific portion the periphery of which is supported by the...
example 3
[0068]In the packing device for an article to be delivered by home delivery service according to the present invention, without limiting to the configuration in which the mat is laminated on the outer layer sheet, it is also possible that, when an airtight sheet is used as an outer layer sheet, as shown in FIG. 14, the outer layer sheet 32 is spread and an airtight sheet as an inner layer sheet 41 is stuck on the rear surface of the outer layer sheet 32, and between the outer layer sheet 32 and the inner layer sheet 41, cushioning bodies 34 are filled and the peripheral edges are sealed, and accordingly, the outer layer sheet 32 and the mat 31 can be configured integrally.
[0069]In this example, the outer layer sheet 32 is longer than the inner layer sheet 41, and the inner layer sheet 41 and the outer layer sheet 32 are overlapped up and down by fitting their one ends together, and the overlapping section of the sheets becomes an article packing region Wa, and the entire periphery o...
