Definitions

  • the present invention relates to, an airtight sheath according to the preamble of claim 1, and more particularly to an airtight sheath for packing and protecting bottles from being damaged by external impact.
  • a buffering sheath is known from US 2004/0163991 A1 and TW 200 946 410 A .
  • 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 or porcelain, 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.
  • an objective of the present invention is to provide an airtight sheath for packing a bottle which is capable of being buffered against external impact.
  • Another objective of the present invention is to provide an airtight sheath capable of protecting a neck portion of a bottle.
