Abstract

A foldable cushion bag includes a main body and a handling unit. The main body includes a bottom wall and a sleeve wall jointed to the bottom wall. The bottom wall and the sleeve wall form a first heat sealed joint therebetween and cooperatively define a space for receiving a bottle. Each of the bottom and sleeve walls includes a multilayered structure having an outermost protecting layer, a first adhesive layer, a heat sealing layer, a second adhesive layer and an innermost cushion layer in that order. The handling unit is connected to the sleeve wall and opposite to the bottom wall. The handling unit is formed with a gripping hole.

Claims

1. A foldable cushion bag, comprising:

a main body including a bottom wall and a sleeve wall that is jointed to said bottom wall, said bottom wall and said sleeve wall forming a first heat sealed joint therebetween and cooperatively defining a space for receiving a bottle, each of said bottom wall and said sleeve wall including a multilayered structure that has an outermost protecting layer, a first adhesive layer, a heat sealing layer, a second adhesive layer and an innermost cushion layer in that order, said innermost cushion layer being immediately proximate to said space; and

a handling unit connected to said sleeve wall of said main body and opposite to said bottom wall, said handling unit being formed with a gripping hole.

2. The foldable cushion bag as claimed in claim 1, wherein said first heat sealed joint is free of said second adhesive layer and said innermost cushion layer.

3. The foldable cushion bag as claimed in claim 1, wherein said sleeve wall is a multi-part wall and has at least two second heat sealed joints which are free of said second adhesive layer and said innermost cushion layer.

4. The foldable cushion bag as claimed in claim 1, wherein said outermost protecting layer is made from a flexible material selected from plastics, fabrics and paper, said heat sealing layer being made from polyolefin, said cushion layer being a foamed plastic.

5. The foldable cushion bag of claim 1, wherein said outermost protecting layer is a plastic film.

6. The foldable cushion bag of claim 1, wherein said outermost protecting layer is made from a plastic selected from the group consisting of polyethylene terephthalate, polyethylene, polypropylene, nylon and combinations thereof.

7. The foldable cushion bag of claim 4, wherein the polyolefin is selected from the group consisting of polyethylene, polypropylene and combinations thereof.

8. The foldable cushion bag of claim 4, wherein said foamed plastic is selected from the group consisting of polyethylene, polystyrene, ethylene-vinyl acetate copolymers, polypropylene, ethylene copolymers and combinations thereof.

9. The foldable cushion bag of claim 4, wherein said fabrics are selected from woven fabrics and nonwoven fabrics.

10. The foldable cushion bag of claim 3, wherein said sleeve wall includes a front wall portion, and a rear wall portion, each of said at least two second heat sealed joints being disposed between one of two opposite sides of said front wall portion and one of two opposite sides of said rear wall portion.

11. The foldable cushion bag of claim 10, wherein said first heat sealed joint is disposed at bottoms of said front and rear wall portions and at an outer periphery of said bottom wall.

12. The foldable cushion bag of claim 10, wherein said handling unit includes a pair of grip portions, each of which is formed as one piece with one of said front and rear wall portions oppositely of said bottom wall, and each of which has said gripping hole 311.

13. The foldable cushion bag of claim 3, wherein said sleeve wall includes a front wall portion, a rear wall portion, and two opposite side wall portions which interconnect said front and rear wall portions, said at least two second heat sealed joints including four heat sealed corner joints, each of which is disposed between one of two opposite sides of one of said front and rear wall portions and one of two opposite sides of one of said side wall portions, said first heat sealed joint being disposed at bottoms of said front, rear and side wall portions and at an outer periphery of said bottom wall.

14. The foldable cushion bag of claim 13, wherein said handling unit includes a pair of grip portions, each of which is formed as one piece with one of said front and rear portions of the sleeve wall oppositely of said bottom wall and has said gripping hole.

15. The foldable cushion bag of claim 13, wherein said handling unit includes a grip portion formed as one piece with one of said front and rear wall portions of the sleeve wall and formed with said gripping hole, and wherein the foldable cushion bag further comprises a closing panel projecting from a position between said grip hole of said handling portion and said one of said front and rear portions toward the other one of said front and rear wall portions, said closing panel extending over said side wall portions and beyond the other one of said front and rear wall portions and having one end abuttable with an outer surface of the other one of said front and rear portions.
