Description

[Detailed description of the invention] This invention is a flexible container used as a fuel or other liquid container in aircraft, vehicles, ships, etc., which can be attached and detached for use while being fixed in a designated place. The present invention relates to a flexible container having flexible fixing means.

Conventionally, this type of flexible container has a tab 14 and a retaining ring 15, as shown in FIG. As shown in FIG. 12, the insertion fitting 20 on the container 19 side is provided so as to fit into the hole 18 made on the fixed side 11, as shown in FIG.

This is done by passing the cord 17 alternately through the grommet 12 of the tab 14 attached to the flexible container 13 and the retaining ring 15 attached to the fixed side 16, and finally passing the cord 17 through the retaining ring 15.
7, the flexible container 13 is joined, and the flexible container 19 is fixed by strongly pushing the insertion fitting 20 attached to the flexible container 19 into the hole 18 of the fixed side 11. .

However, the metal fittings 14 and 20 increase the weight, and it is difficult to attach and detach the container in a narrow space, and a flexible container has the disadvantage that it is difficult to maintain its own shape.

If the flexible container cannot maintain its shape, the space where the flexible container is installed is often narrow when refilling after consuming the contents, such as fuel, and the flexible container deflated due to the consumption of the contents may get caught in the surrounding area. It may not return to its original shape, making it impossible to refill it with the required amount of contents.

The present invention solves the conventional drawbacks, and aims to provide a flexible container that is easy to attach and detach even in a narrow space, is lightweight, and has a fixing means that can reliably maintain its own shape. .

That is, the present invention relates to a flexible container that is used as a fuel or other liquid container in aircraft, vehicles, ships, etc. by being fixed at a predetermined location, and a pair of velvet fasteners attached to the fixed side. Another piece of velvet fastener is attached to the periphery opposite to the button, and by connecting this velvet fastener on the container side to the matching velvet fastener on the fixed side, a fixing means is provided in which the self-shape is supported from the surroundings. A flexible container is provided.

Hereinafter, the present invention will be described in detail with reference to the drawings.

FIG. 1 is a perspective view showing an embodiment of the present invention, in which a velvet fastener piece 2 is attached to the periphery of a flexible container 10.

The velvet fastener 2 attached to the periphery of the container 10 is located opposite to a pair of velvet fasteners (not shown) attached to the stationary side,
In addition, by connecting the velvet fastener 2 of the container 1 to the velvet fastener on the fixed side, the shape of the container 1 can be constantly supported from the surroundings.

Further, 3 is a cap provided around the opening 4 for injecting or dispensing liquid into the container 1.

FIG. 2 is an enlarged cross-sectional view of the attachment portion of the velvet fastener 2, which is firmly attached to the flexible container 1 with adhesive, sewing, or the like.

The flexible container 1 is made of a rubber or synthetic resin sheet, rubberized cloth, etc., and when sewing a velvet zipper with a sewing machine, the flexible container 1 is made of a relatively strong material such as a rubberized cloth. Preferably, it is made of material or provided with reinforcing strips along the seams.

When a flexible container is constructed in this way, it can be fixed with one touch by attaching the other velvet fastener to the fixed side and pressing the button.

After the flexible container is fixed, the shape of the flexible container is supported from the surrounding area by the fixed side, so even if the contents such as fuel are consumed, the flexible container will not deflate and will be secure. can be refilled with the required amount of contents.

Particularly, in the present invention, a velvet fastener is used as a fixing means, and since the velvet fastener is joined with almost no play, it is possible to ensure that the flexible container maintains its own shape.

Alternatively, the flexible container can be connected to the fixed bell vent fastener simply by injecting liquid into the flexible container and expanding it.

Fig. 3 shows the flexible container according to the present invention being used as an aircraft fuel container, in which the flexible container 1 has its own shape supported from the periphery by velvet fasteners 2 attached to its periphery. It is fixed to the fuselage 5 in this state.

FIG. 4 is an enlarged sectional view of the joint between the container 1 and the fuselage 5, and shows the velvet fastener 2 attached to the flexible container 1.
and the velvet fastener attached to the fuselage 5 are joined together with almost no play.

Generally, aircraft fuel containers are installed in extremely narrow spaces such as wings, but the container according to the present invention is extremely easy to install and remove, so it can be easily installed even in such places.

Furthermore, by attaching a velvet fastener to the periphery of the flexible container, it is possible to support the container from the periphery and maintain its shape even in flexible locations.

Reference numeral 3 denotes a mouthpiece that forms an opening 4 for injecting and dispensing fuel.

The flexible container according to the present invention can also be used by joining containers together.

Figures 5 and 6 show an embodiment of the present invention in which flexible containers are joined together, where 1 and 1' are the flexible containers, 6 is the flange of the reinforcing panel, and T is the panel body. show.

Figure 7 shows the case where a reinforcing panel is used for the above joining.
Figure 8 shows a cross section of the joint when no reinforcing panel is used, and shows the velvet fastener 2 attached to the flexible container 1 and the velvet fastener 2 attached to the other flexible container 1' or the panel main body T side. The fasteners are joined together as a pair to form a button, and the facing joints of the flexible containers 1 and 1' prevent the flexible containers 1 and 1' from rubbing against each other due to rocking, and also prevent both The bridging strap 8 and the velvet fastener attached to the inside of the flange 6 of the reinforcing panel act as a strength member to prevent the flexible containers 1, 1' from coming apart.

Also in this case, although not shown, velvet fasteners are provided around the periphery of the flexible containers 1 and 1' so that the self-shape of the flexible containers 1 and 1' can be supported from the periphery. Trigram.

At this time, the panel main body 7 serves to assist in maintaining the shape of the flexible container 1.degree. 1'.

This allows one flexible container to function as a flexible container with two or more functions.

Next, the advantages of the present invention will be listed.

1. It is extremely lightweight because it uses velvet fasteners for connection.

2. Connection can be made by simply pressing a portion of the velvet fastener from inside the flexible container or from the fixed side, so it can be easily installed even in narrow spaces.

3. Since the velvet fastener is attached around the flexible container and the velvet fastener is joined with almost no play, the flexible container can reliably maintain its own shape.

4. By connecting a plurality of flexible containers each having a pair of velvet fasteners attached to the connecting portion, there is an advantage that the container can be handled as a single flexible container or vice versa.

5. By connecting a reinforcing panel to a flexible container with a velvet fastener, it is possible to reinforce the single or entire surface of the container, and it also has great benefits such as being able to help maintain its own shape. It is.
