Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air cushioning material used to reduce the impact on an object to be secured at the time of packing and to fill a gap between an article and a container.

[0002]

2. Description of the Related Art The applicant of the present invention has developed an air cushioning material having a large number of individual airbags continuously inflated by blowing air.
120288, Japanese Patent Application No. 2-270115).

As shown in FIG. 4, the above-described air cushioning material has a large number of basically inflatable individual airbags (1) formed therethrough and penetrates each airbag (1). And a blowing tube (2) forming a common air blowing passage, the blowing tube (2) having at least one self-sealing valve (3) located in each airbag (1). Each airbag (1) has a blowing tube (2) penetrated into a flat bag-shaped member formed by laminating two heat-fusible films in a band shape and heat-sealing both side edges thereof. From above, the bag-shaped members are heat-sealed at predetermined intervals (in FIG. 4, (4) indicates a heat-sealed portion) to form individually partitioned airbags (1). You. When the bag-shaped member is heat-sealed, the bag-shaped member is heated and pressurized by interposing a non-fusible tape or powder on at least the inner peripheral surface of the blow-in tube (2). The upper film and the lower film, and the upper film and the lower film of the bag-like member and the blowing tube (2) are fused to each other, but the inner peripheral surfaces of the blowing tube (2) are not fused and leave an air passage. It is configured as follows.

When using the above-mentioned air cushioning material, it is wrapped around an object to be fixed, for example, a glass bottle or the like, or inserted into a gap between an article and a storage container. When air is blown by blowing means such as airbags, individual airbags (1)
The self-sealing type valve (3) is opened to blow air into each airbag (1) to inflate each airbag (1). When air blowing is stopped when each airbag (1) is inflated to a required limit, the self-sealing valve (3) is closed by air pressure in the airbag (1), and each airbag (1) is inflated. Maintain and act as a buffer or packing.

[0005]

By the way, once the air cushion (1) is inflated by blowing air into the air cushion (1), individual airbags (1) are required to reduce the volume.
Must be cut one by one with a knife (knife, scissors, etc.) to bleed the air. It is necessary to prepare the knife, and when the airbag (1) is torn with the knife, the knife touches a finger or a fixed object. Risk of damage.

[0006] Therefore, as a method of bleeding air without using a tool such as a blade, a tear portion such as a V notch is provided in a heat seal portion on both side edges of the airbag (1), and the tear portion is provided. There is a method of tearing the airbag (1) by using the airbag (1). In this method, a tear portion must be provided in all of the individual airbags (1) connected in series, and the individual airbags (1) must be separated. It must be torn one by one, and the air bleeding operation is very troublesome.

The present invention has been made in view of the above circumstances, and has as its object to provide an air cushioning material that can easily and quickly bleed air without using a tool.

[0008]

In order to achieve the above object, the present invention is to provide a large number of individual airbags which are inflated by blowing air, and the airbags are connected to the individual airbags in the direction in which the airbags are connected. In the air cushioning material having an opening band integrally attached along the line, the opening band is partially fused and attached to each airbag.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiments of the present invention shown in FIGS. 1 to 3 will be described below. 1 to 3, parts corresponding to those in FIG. 4 showing the prior art are denoted by the same reference numerals, and the description of the same items will be omitted.

FIG. 1 is a perspective view showing an air cushion according to an embodiment of the present invention, and FIG. 2 is a perspective view showing the air cushion according to the embodiment of the present invention when air is released.

As shown in FIGS. 1 and 2, the air cushioning material of the present invention has an opening band (5) for collectively bleeding the individual airbags (1). This opening band (5)
Is made of a heat-fusible film having a strength higher than that of the airbag (1) so as to withstand tearing of the airbag (1), and the individual airbags (1) are arranged along the direction in which the airbags (1) are connected. It is point-fused and individually attached to the individual airbags (1) in a state addressed to above (FIG. 1).
The hatched portions in (2) indicate the fusion point (6)). Attachment of the opening band (5) is performed by point fusion to the individual airbag (1) at the same time as the step of forming the individual airbag (1).

The use of the air cushioning material of the present invention is the same as in the conventional case. In other words, when air is blown from the end of the blowing tube (2) by blowing means such as an air compressor, after wrapped around a fixed object, for example, a glass bottle or the like, or inserted into the gap between the article and the storage container, The self-sealing valves (3) of the individual airbags (1) are opened to blow air into each airbag (1) and inflate each airbag (1). When air blowing is stopped when each airbag (1) is inflated to a required limit, the self-sealing valve (3) is closed by air pressure in the airbag (1), and each airbag (1) is inflated. maintain.

In the air cushioning material of the present invention, at the time of disposal after use, put a finger on the opening band (5) and pull the opening band (5) along the direction in which the airbag (1) is connected. Since the strength of the tear band (5) is higher than that of the air bag (1), the individual air bags (1) are successively torn sequentially at each fusion point (6) of the tear band (5), whereby The individual airbags (1) can be deflated all at once.

According to the air cushioning material of the present invention, the airbags (1) can be deflated all at once by simply putting a finger on the tear-off band (5) and pulling it, so that a tool (blade) is used. Since air can be easily and quickly vented without using tools, air can be vented without using tools, so that the risk of damaging fingers and objects by the tools can be prevented. Also, since the tear-off band (5) is partially fused and attached to each airbag (1), an adhesive is used when the tear-off band (5) is formed into each airbag (1). Can be attached to the individual airbags (1) without requiring any additional cost. Furthermore, since the tear band (5) is partially fused to the individual airbags (1), portions other than the fusion point (6) of the tear band (5) are released from the airbag (1). When pulling the tear-off band (5), it is easy to put a finger on the tear-off band (5), and it is possible to put a finger on any position of the tear-off band (5). The air can be vented even from the bag (1), and it is very convenient because it can be wrapped around the object to be secured by utilizing the gap between the airbag (1) and the opening band (5).

Incidentally, in the air cushioning material of the present invention, the airbag (1) can be easily torn by modifying the shape of the fusion point (6) of the opening band (5). Are shown in FIGS. 3 (a) to 3 (c). FIG.
The shape of the fusion point (6) of the tear band (5) shown in (c) is determined by the shape of the mold when the tear band (5) is spot welded to the airbag (1).

In the air cushioning material of the present invention, the opening band (5) may be thin or thread-like as long as it is strong enough to withstand the tearing of the airbag (1).

Furthermore, in the above-described embodiment, air is blown from the blowing tube (2) into the individual airbags (1) via the self-sealing valve (3) to inflate the airbags. Even if the air cushion material in which the individual airbags (1) are inflated in advance by heat sealing is used, the opening band (5) may be point-fused to the individual airbags (1).

[0018]

As described above, according to the present invention,
It is possible to provide an inexpensive air cushioning material that can easily and quickly release air with a safe operation without using a tool (blade). In addition, this air cushioning material can be used to place a finger on an arbitrary position of the opening band. Thus, air can be vented from any airbag, and it is very convenient because it can be wrapped around an object to be secured by utilizing the gap between the airbag and the opening band.
