- a traditional wrapping material is generally provided with a soft inner pad, such as foam, on a peripheral side thereof for protecting articles to be wrapped so as to prevent the articles from being damaged or broken by external vibration .
- the soft inner pad is required to be attached to the wrapping material with additional processes to avoid moving or coming off from the wrapping material, but the additional processes of attaching the soft inner pad are not only cumbersome but also costly to assembly.
- an air inflatable structure is designed to resist impact, with air columns filled with air, and is capable of protecting articles from being vibrated. Due to the great utility, the inflatable air packing materials are to replace traditional wrapping materials by degrees, especially in the field of packing high-tech products, for example, such as mobile phones or display panels. Recently, air packing materials are also utilized to wrap fragile articles made of glass orporcelain, such as wine bottles, in a way that a bottle is surrounded by several air packing pads in a container. Specifically, a bottle is placed on an air packing pad and enveloped by separate air packing pads. Though the bottle can be protected by the air packing pads, the bottle is not well positioned because the air packing pads are separately placed.

- The present invention relates to a buffering sheath, and more particularly to an airtight sheath for packing and protecting bottles from being damaged by external impact.
- A traditional wrapping material is generally provided with a soft inner pad, such as foam, on a peripheral side thereof for protecting articles to be wrapped so as to prevent the articles from being damaged or broken by external vibration . However, the soft inner pad is required to be attached to the wrapping material with additional processes to avoid moving or coming off from the wrapping material, but the additional processes of attaching the soft inner pad are not only cumbersome but also costly to assembly.
- In view of the above-mentioned drawbacks, an air inflatable structure is designed to resist impact, with air columns filled with air, and is capable of protecting articles from being vibrated. Due to the great utility, the inflatable air packing materials are to replace traditional wrapping materials by degrees, especially in the field of packing high-tech products, for example, such as mobile phones or display panels. Recently, air packing materials are also utilized to wrap fragile articles made of glass orporcelain, such as wine bottles, in a way that a bottle is surrounded by several air packing pads in a container. Specifically, a bottle is placed on an air packing pad and enveloped by separate air packing pads. Though the bottle can be protected by the air packing pads, the bottle is not well positioned because the air packing pads are separately placed. In other words, separate pieces of packing pads are likely to move in the container whereby rendering the bottle fragile to impact. Besides, it is difficult to hold separately placed air packing pads together with the bottle, or to take out the bottle together with separate air packing pads from the container. As a result, traditional air packing pads fail to provide well protection for bottles while bottles are taken out of the container, or while bottles are loaded in the container.
- Consequently, it is imperative to improve an inflation structure to be capable of securely positioning fragile bottles and effectively protecting bottles from being impacted by external force.

- The airtight sheath for packing a bottle of claim 1, wherein the first buffering unit (11) is provided with multiple bending nodes (13) formed on at least several of the first air columns (11) corresponding in position to the shielding portions (44) of the cover, and the bending nodes (13) are arranged in parallel and in alignment with each other and heat-sealed to allow the first air columns (11) to be bendable with respect to the bending nodes.
- The airtight sheath for packing a bottle of claim 2, wherein the cover further comprises two protection units (45), which are heat-sealed to the connecting air columns in such a way that the connecting air columns (41) and the lid air column (42) are located between the two protection units (45), each of the protection units (45) comprises a plurality of divided air columns (451) and protection air columns (452) extending in the packing space (10), the divided air columns (451) extend and bend from the first air columns (11), each of the divided air columns (451) has a width smaller than that of each of the first air columns (11), and an interval heat-sealing line (453) is provided between and along either two of the adjacent divided air columns (451) for facilitating bending of the divided air columns (451).
- The airtight sheath for packing a bottle of claim 3, wherein two of the divided air columns (451) are defined as a set, which is in alignment with a corresponding one of the first air columns.
- The airtight sheath for packing a bottle of claim 1, wherein the bottom air columns (31) of the bottom unit integrally extend and bend from the first air columns (11) and the second air columns (21), and two recessed sealing lines (32) respectively formed at and bending inwardly from opposite end portions of the bottom unit (31) and connecting the distal heat-sealing sides (12) of the first buffering unit (1) so as to form two recessed portions between the bottom unit (3) and the first and second buffering units (1, 2).
- The airtight sheath for packing a bottle of claim 5, wherein each of the bottom air columns (31) has at least a sealing node (311) being heat-sealed, the sealing nodes (311) are arranged in alignment with each other, and the sealing nodes (311) and the recessed sealing lines (32) further enable the bottom air columns to bend toward the packing space (10) when being inflated, such that the bottom unit (3) functions as a reversed hammock-like cushioning structure for supporting the bottle (5).
- The airtight sheath for packing a bottle of claim 1, wherein the airtight sheath is capable of being connected with another airtight sheath in such a way that two adjacent distal heat-sealing sides (12) of the two airtight sheaths are heat-sealed, where the two adjacent distal heat-sealing sides (12) are further provided with a plurality of breakable sections (121) formed thereon and spaced apart from each other, so that the two airtight sheaths are separable by tearing the breakable sections (121).
- The airtight sheath for packing a bottle of claim 1, wherein the distal heat-sealing sides (12) respectively extend upward to a location lower than the cover (4), whereby forming gaps (120) between the distal heat-sealing sides (12) and a top of the airtight sheath (100), so as to allow the first or second buffering units (1, 2) to be bendable with respect to the gaps (120).
- The airtight sheath for packing a bottle of claim 1, wherein the second air columns (21) of the second buffering unit (2) extend upward to a height corresponding to the cover (4), and the two outer films (101, 102) extend upward of the second buffering unit (2) to form an inflation path (103) above the second air columns (21) for enabling air to flow over the inflation path (103) and inflate the airtight sheath (100).
