Description

[Detailed Description of the Invention] The present invention relates to a novel packing material used when packing objects into boxes.

A conventional example used for such a purpose is, for example, as seen in Japanese Patent Application Laid-open No. 48-32072, in which air chambers communicating with each other are integrally arranged in parallel vertically and horizontally to form a sheet having a constant area as a whole. Those that did were common.

However, although such a sheet-like material is convenient when covering one item by placing it on the entire inner surface of the box, it is useful when packing multiple items inside the box, or when placing an item inside a part of the box. When storing it, it is rather inconvenient because it is too bulky.

The purpose of this invention is to solve these problems, that is, it can wrap items in the minimum necessary compactness, eliminating bulk, thereby minimizing the increase in the overall weight of the package, and reducing transportation fees, etc. The aim is to provide a new packaging filler that can also contribute to savings.

The packing material of the present application, which was devised to achieve such a purpose, is a sealed bag that swells when filled with gas and is soaked when discharged, and is provided with a filling port and a discharge port. It can be freely connected to the filling and discharging ports of other airtight bags, and as shown in Figure 3, a large number of bags are joined together and inserted between the carton and the contents compartment in an immersed state, and then allowed to swell. This is used for purposes such as fixing the contents inside the carton to prevent damage to the contents.

In the illustrated embodiment, a thermoplastic soft synthetic resin sheet is high-frequency welded to form an airtight bag 1 that swells when filled with air and is soaked when discharged. A short tubular discharge port 3 is attached to each of the lower edges, and a female member 4 and a male member 5 are attached to the filling port 2 and discharge port 3 for joining with the filling port and discharge port of another airtight bag. .

In the figure, 6 indicates a lid plug, and 7 indicates a tail plug.

The present invention does not limit the material of the airtight bag, the structure of the joint between the filling port and the discharge port, etc. to those of the embodiments.

As described above, the present invention provides a filling port and a discharge port in a sealed bag that expands when filled with gas and is soaked by discharging gas, and connects these filling ports and discharge ports with the filling port and discharge port of another sealed bag. Since they can be assembled freely, the contents can be wrapped compactly by piecing together as many airtight bags as needed depending on the size of the contents and the placement location. This has the effect of reducing transportation charges for packaged items, and this effect is particularly noticeable when packing multiple items into a box or storing items in a portion of the box. It is.
