Description:

BACKGROUND OF THE INVENTION

1. Field of Invention

The present invention relates to a packing cushion, and more particularly to a packing cushion with multilayer substrates.

2. Related Art

Generally, when wrapping an article, the article is put into a cardboard case directly. However, the cardboard case can only contain the article without the function of buffer protection and make the article easy to be shaken and damaged during transportation. So a buffering material will be used for packing to increase the buffer protection of the cardboard case. A common way is to stuff foam materials between the article and the cardboard case, and the soft of the foam material may protect the article with buffer protection. Even so, the foam material is expansive to raise the packing cost and fail to meet economical effects. Besides, the foam material is hard to be processed and easy to cause environmental problems. Moreover, although the foam material may attach to the surface of the article very closely, it is still lack of crash-proof effects and allows the article being crashed and damaged frequently.

Another common buffering material is the Styrofoam. The Styrofoam may be used to pack the article first and then put into the cardboard case to prevent the article from any impact during transportation. Although the Styrofoam may prevent the article from being shaken and damaged, it has fluffy volume occupying large space and is hard to be decomposed by the microorganism; the incineration process releases poison gas which is harmful to human body and causes serious environmental problems. As the environmental awareness has been increased broadly nowadays, the Styrofoam is no longer an ideal packing material. Furthermore, the articles with various sizes and shapes cannot share the same Styrofoam material. An extra Styrofoam with different dimensions means a waste of resources and a raise on the packing cost of the article.

Therefore, the issue about providing the article a satisfied buffer protection, preventing the article from being damaged by impacts or scratches during transportation, solving the environmental problems caused by the buffering materials in the prior art, and further reducing the packing cost, has become a significant subject desired to be improved by the inventor of the present invention and those skilled in the art.

SUMMARY OF THE INVENTION

The problems noted above are solved in large part by providing a packing cushion with multilayer substrates. In the present invention, the packing cushion packs an article, provides buffer protection and includes: at least one tube sheet that has plural air chambers to provide buffer protection after air-filling and expanding; and at least one slice body(s) that attaches closely to a side of the tube sheet to prevent the tube sheet from being poked through and broken.

According to the exemplary embodiment of the invention, when the tube sheet is expanded after filling air, the slice body(s) or the tube sheet may be used to pack the article and provide the article with buffer protection by the tube sheet. Therefore, being damaged or scratched during transportation may be avoided. Furthermore, the slice body(s) may prevent the tube sheet from being poked through and leaking air. Thereby the packing cost of the article may be reduced, meanwhile the environmental pollution problems caused by the buffering materials in the prior art may be solved.

Further scope of applicability of the present invention will become apparent from the detailed description given hereinafter. However, it should be understood that the detailed description and specific examples, while indicating preferred embodiments of the invention, are given by way of illustration only, since various changes and modifications within the spirit and scope of the invention will become apparent to those skilled in the art from this detailed description.

DETAILED DESCRIPTION OF THE INVENTION

Please refer to FIGS. 1A, 1B and 1C, which illustrate a first embodiment of the present invention. FIG. 1A is a plane diagram before filling air. FIG. 1B is a perspective diagram after filling air. FIG. 1C is a cross-sectional diagram after filling air.

A packing cushion with multilayer substrates 6 includes two outer films 2a and 2b, and the slice body(s) 15.

The outer films 2a and 2b are up-down stacked with each other.

Along the thermal-sealing lines 3a, 3b, 3c, 3d, tube sheet(s) 8 are formed by thermal-sealing. The tube sheet(s) 8 include air chamber(s) 11 and filling hole(s) 12. Several nodes 14a may be formed by further thermal-sealing the tube sheet(s) 8. The tube sheet(s) 8 may be bended along the nodes 14a.

The tube sheet(s) 8 may be laid in parallel, stacked in sequence or deposed vertically beside a side of the slice body(s) 15, and be fixed on the slice body(s) 15 through adhering means, or fixed on a side of the slice body(s) 15 through thermal sealing. The slice body(s) 15 may be adhered on the surface of the air chamber(s) 11 levelly. Furthermore, the air chamber(s) 11 may be bended along the nodes 14a to form stacked multiple layers and become plural stacked buffering tubes with a multilayer buffering function.

The aforesaid outer films 2a and 2b may be made of polyethylene (PE). The slice body(s) 15 may be made of soft material(s), such as Polyvinylchloride (PVC), Polypropylene (PP), Enhanced Polyethylene (EPE), Enhanced Polypropylene (EPP), cloth material, foam material, PE-based air bubble sheet, corrugated paper, paper material, or paper-like material.

The air entering the filling hole 12 fills and expands the tube sheet(s) 8. Then, the slice body(s) 15 may pack the article 20, and the tube sheet(s) 8 may provide the article 20 with buffer protection. Accordingly, any sharp angles of the article 20 may avoid poking through the tube sheet(s) 8 and leak air from the air chamber(s) 11. Eventually, the packing cost of the article may be reduced, and the environmental pollution problems caused by the buffering materials in the prior art may be solved. Furthermore, the user may directly use the tube sheet(s) 8 to pack the article 20 and provide buffer protection, then use the slice body(s) 15 to protect the tube sheet(s) 8 from being poked through and leaking air. The tube sheet(s) 8 may be used to completely pack the article 20, or only a portion of the article 20; two or more tube sheet(s) 8 may be used to pack the article 20 in different directions and stack with each other.

Please refer to FIGS. 2A and 2B, which illustrate a second embodiment of the present invention; FIG. 2A is a plane diagram before filling air and FIG. 2B is a perspective diagram after filling air.

After two outer films 2a and 2b are up-down stacked, a tube sheet(s) 8 may be formed by thermal-sealing along the thermal-sealing lines 3a, 3b, 3c, 3d, 3e. Several air chambers 11 and a filling hole 12 may be formed through thermal-sealing the outer films 2a and 2b. Afterwards, plural nodes 14a may be formed on the air chamber(s) 11 by means of thermal-sealing to allow the air chamber(s) 11 bending along the nodes 14a.

Please refer to FIGS. 3A and 3B, which illustrate a third embodiment of the present invention; FIG. 3A is a plane diagram before filling air and FIG. 3B is a cross-sectional diagram after filling air.

A packing cushion with multilayer substrates 6 includes: two outer films 2a and 2b, two inner films 1a and 1b, a filling passage 9, plural air chambers 11, plural input passages 13 and plural slice bodies 15.

The two outer films 2a and 2b are up-down stacked.

The two inner films 1a and 1b are adhered with the outer films 2a or 2b. And between the inner films 1a and 1b, heat-resistant material 1c is applied to form a continuous check valve or a single filling check valve as a passage for air flow.

Tube sheet(s) 8 may be formed through thermal-sealing the thermal-sealing lines 3a, 3b, 3c, 3d, 3e; wherein the two outer films 2a and 2b and the two inner films 1a and 1b are thermal-sealed to form the filling passage 9 between the outer films 2a and 2b. The filling passage 9 passes through the thermal-sealing line 3e and has a filling hole 12 connecting with external air. Thermal-sealing the outer films 2a and 2b may also form the plural air chambers 11. Besides, thermal-sealing the air chamber(s) 11 may further generate plural nodes 14a to allow the air chamber(s) 11 bending along the nodes 14a.

Between the two inner films 1a and 1b, heat-resistant material 1c is applied in sequence. For example, print heat-resistant glue or ink by printing means. By means of thermal sealing, the two inner films 1a and 1b may the input passage 13 without attaching to each other.

The tube sheet(s) 8 may be laid in parallel, stacked in sequence or deposed vertically between the two slice bodies 15, and be fixed between the two slice bodies 15 by adhering or thermal sealing means. Furthermore, the air chamber(s) 11 may be bended along the nodes 14a to form stacked multiple layers and become plural stacked buffering tubes with multilayer buffering function. The tube sheet(s) 8 may be inserted between the two slice bodies 15 after bending along the nodes 14a.

The air entering the filling hole 12 fills and expands the tube sheet(s) 8. Then, pull the two inner films 1a and 1b outwards to open the input passage 13, thereby using the air in the filling passage 9 to fill and expand the air chamber(s) 11. When a continuous check valve is formed between the two inner films 1a and 1b, the air in the filling passage 9 may fill all the air chamber(s) 11 at the same time through the continuous check valve. The two inner films 1a and 1b may form a single filling check valve in-between to allow the air in the filling passage 9 to fill each of the air chambers 11. The air pressure at the curve portion of the input passage 13 is larger than the two lateral portions, so for the air to enter the filling passage 9 is easier than to leak out. When the internal pressure in the air chamber(s) 11 is increased, the curve portion of the input passage 13 will be pressed hardly to achieve an air locking effect. The internal pressure of the air in the air chamber(s) 11 also press the two inner films 1a and 1b to attach onto the outer film 2a or 2b closely, packing the input passage 13 and sealing the air chamber(s) 11 to form an airtight effect without leaking air.

The slice body(s) 15 may be bended to form a cube, cuboid, polyhedron, ring, circle, cylinder or camber body with a containing space for the tube sheet(s) 8; the tube sheet(s) 8 may be laid in parallel, stacked in sequence or deposed vertically in the containing space. In addition, the tube sheet(s) 8 may be fixed in the containing space by adhering or thermal-sealing means.

According to the structure disclosed in the present invention, the packing cushion with multilayer substrates 6 may further includes a outer box 30. The outer box 30 has a container space 32. After the tube sheet(s) 8 and the slice body(s) 15 pack and pack the article 20, the article 20 may be placed into the container space 32 of the outer box 30 for transportation.

Please refer to FIGS. 4A, 4B, 4C and 4D, showing the third embodiment of the present invention. FIG. 4A is an explanatory diagram (I) of the bending operation; FIG. 4B is an explanatory diagram (II) of the bending operation; FIG. 4C is an explanatory diagram (III) of the bending operation; and FIG. 4D is an explanatory diagram (IV) of the bending operation.

To pack the article 20 more completely, the slice body(s) 15 may be cut into any proper shape or size. Or, the slice body(s) 15 may be bended for attaching onto the article 20 more smoothly. For example, bend the slice body(s) 15 as a camber body and allow the slice body(s) 15 attaching onto the surface of the article 20 completely; or bend the slice body(s) 15 as a cylinder and allow the article 20 being contained in the central space of the cylinder. Eventually, the air chamber(s) 11 may provide the article 20 a buffer protection. If the contained article 20 has a sharp angle, the slice body(s) 15 may prevent the air chamber(s) 11 from being poked through and leaking. The slice body(s) 15 may also be bended to include at least one right angle with its two perpendicular portions adhering onto the air chamber(s) 11. The air chamber(s) 11 may be bended along the nodes 14a to attach closely onto the slice body(s) 15. The slice body(s) 15 may be made of Enhanced Polyethylene (EPE), Enhanced Polypropylene (EPP) or PE-based air bubble sheet, to provide the article 20 with a secondary buffering function and strengthen the effects of absorbing vibration and buffering.

Please refer to FIGS. 4E and 4F, showing still the third embodiment of the present invention. FIG. 4E is an explanatory diagram (I) that shows the bending operation to form a bag body, and FIG. 4F is an explanatory diagram (II), showing the bending operation to form the bag body.

The tube sheet(s) 8 may be bended along the nodes 14a and thermal-sealed the two lateral sides of the tube sheet(s) 8 to form a bag body, thereby containing the article 20 into the bag body for providing the article 20 with a buffering function. The slice body(s) 15 may be located at the inner and/or outer surface of the bag body to prevent the tube sheet(s) 8 from being poked through and leaking air.

Please refer to FIGS. 5A, 5B, 5C and 6D, which show a fourth embodiment of the present invention. FIG. 5A is an explanatory diagram (I) after filling air; FIG. 5B is an explanatory diagram (II) after filling air; FIG. 5C is an explanatory diagram (III) after filling air; and FIG. 5D is an explanatory diagram (IV) after filling air.

The aforesaid slice body(s) 15 may be bended as a box body 16. The box body 16 includes a filling space 160 for containing the tube sheet(s) 8. The tube sheet(s) 8 may be laid in parallel, stacked in sequence or deposed vertically inside the filling space 160 to fix onto the box body 16 or inside the filling space 160 through adhering or thermal-sealing means.

Please refer to FIGS. 6A˜6H, which also show the fourth embodiment of the present invention. FIG. 6A is an explanatory diagram (I) of the bending operation; FIG. 6B is an explanatory diagram (II) of the bending operation; FIG. 6C is an explanatory diagram (III) of the bending operation; FIG. 6D is an explanatory diagram (IV) of the bending operation; FIG. 6E is an explanatory diagram (V) of the bending operation; FIG. 6F is an explanatory diagram (VI) of the bending operation; FIG. 6G is an explanatory diagram (VII) of the bending operation; FIG. 6H is a plane diagram for FIG. 6G before filling air.

To pack the article 20 more completely, a box body 16 with various shapes and sizes may be used such as an italic box body 16 with an arc surface, U-shaped or cylinder box body 16. Furthermore, place at least one tube sheet(s) 8 inside the filling space 160 of the box body 16 to carry or hold the article 20 with different shapes and sizes.

The box body 16 also has a holding space 162 to hold one angle of the article 20 and prevent the article 20 from damages or scratches during transportation. Furthermore, the box body 16 may be a rectangular case body to contain the article 20 with the central space inside the box body 16. Then the box body 16 with the contained article 20 may be placed into an outer box 30 to form a box-in-box structure and strengthen the protection effects of absorbing vibration and buffering.

Furthermore, the tube sheet(s) 8 includes an unfillable area 14b located at the middle air chamber(s) 11. Therefore, after the tube sheet(s) 8 are bended along the nodes 14a and the unfillable area 14b, the tube sheet(s) 8 will be able to provide a buffer protection at the two perpendicular portions and the lateral portion of the article 20 (or the three adjacent perpendicular portions of the article 20). Consequently, a single tube sheet 8 may provide a buffering function in multiple directions to enhance the effects of the tube sheet 8 for absorbing vibration and buffering.

Please refer to FIGS. 7A and 7B, showing a fifth embodiment of the present invention. FIG. 7A is an explanatory diagram (I) for actual implementation, and FIG. 7B is an explanatory diagram (II) for actual implementation.

When the slice body(s) 15 is bended as a case body 18, the tube sheet(s) 8 may be attached closely to the inner or outer surface of the case body 18 and the article 20 may be contained in a carry space 181 of the case body 18. Furthermore, the tube sheet(s) 8 may be fixed on the case body 18 through adhering or thermal-sealing means. And when the tube sheet(s) 8 are attached to the outer surface of the case body 18, the packing cushion with multilayer substrates 6 may be placed into the outer box 30 for absorbing vibration and buffering protection. Meanwhile, prevent the tube sheet(s) 8 from being poked through and leaking air.

The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
