[0003]

[Problems to be solved by the device]

 However, this product is bulky, requires a large area for storage, and is troublesome to carry.

In view of the above situation, it is an object of the present invention to provide a storage case capable of compactly storing a telescopic duct.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides a storage case for storing an expansion duct that can be expanded and contracted in a length direction by compressing the expansion duct in the length direction and storing the bottom surface of the storage case. A suction hole connected to the suction source is provided, and a blocking piece that is in contact with the side surface of the expansion duct to prevent the expansion duct from popping out is provided on the entrance side of the storage case. Therefore, insert one end of the expansion duct into the storage case, bring the end of the expansion duct into contact with the bottom surface, and connect the vacuum source to the suction hole with the other end of the expansion duct capped. If the expansion duct is pushed into the storage case while sucking the air in the expansion duct, the expansion duct of about 5 to 10 times the length can be easily stored in the storage case. Moreover, when the telescopic duct is taken out of the storage case, the telescopic duct does not pop out due to the blocking piece, and the required amount can be pulled out and used.

According to a second aspect of the present invention, in a storage case that stores a telescopic duct that can expand and contract in the length direction, a suction hole communicating with a suction source is provided in the storage case, and the storage case is provided. A blocking piece is provided on the entrance / exit side in contact with the side surface of the expansion / contraction duct to prevent the expansion / contraction duct from popping out. The blocking piece is a flap provided on the entrance / exit side of the storage case, It is characterized in that it is formed by inserting the insert piece into the notch hole provided on the side surface of the storage case. With such a configuration, the blocking piece can be formed by effectively utilizing the flap.

[Embodiment of the invention]

 Embodiments illustrating the present invention will be described. In the drawing, reference numeral 1 shows a storage case that stores a telescopic duct A which can be expanded and contracted in the length direction by compressing in the length direction, and the storage case 1 is formed in a rectangular shape by using corrugated cardboard, a resin plate, or a metal plate. Then, the bottom plate 1a of the storage case 1 is provided with a suction hole 3 connected to the suction source 2. The suction hole 3 was formed by making a diametrical cut in the bottom plate 1a. Reference numeral 4 denotes a blocking piece on the entrance / exit side of the storage case 1, which blocks the expansion duct A from jumping out of the storage case 1 when the expansion duct A is taken out by contacting the side surface of the expansion duct A. The piece 4 is formed by bending a flap 6 projecting toward the entrance / exit 5 side from both sides of the entrance / exit 5 in the storage case, and inserting a piece 6a provided at the tip of the flap 6 into a cut hole 7 provided on the side surface of the storage case 1, As shown in FIG. 2 and FIG. 4, the blocking piece 4 bulging inward was formed on both sides in the vicinity of the inlet / outlet 5 by inserting the blocking piece 4. Reference numeral 8 denotes a lid piece that closes the doorway 5.

In the illustrated example, the blocking pieces 4 and 4 are formed by using the flaps 6 and 6, but this may be formed by attaching another member to the entrance / exit side of the storage case 1.

As shown in FIG. 2, the expansion duct A is stored in the main storage case 1 by inserting a nozzle connected to the suction source 2 into the suction hole 3 and inserting the bottom plate of the storage case 1 into the storage case 1. The suction source 2 is operated in a state in which the telescopic duct A is inserted to the position where the tip of the telescopic duct A comes into contact with 1a, and the cap 9 is applied to the other end of the telescopic duct A. Then, since the inside of the expansion duct A has a negative pressure, the expansion duct A can be drawn into the storage case 1, and the expansion duct A is pushed in if necessary. At this time as well, since the inside of the expansion duct A is under negative pressure, it is easy to push.

When the expansion duct A has been stored in the storage case 1, the insertion pieces 6 a at the tips of the flaps 6, 6 are inserted into the cut holes 7, 7 provided on the side surface of the storage case 1 to prevent the blocking piece 4. Or the blocking piece 4 is formed at a construction site.

If the expansion duct A is taken out from the storage case 1 in this state, a necessary amount can be taken out without the expansion duct A protruding from the storage case 1.

By using this storage case 1, the expansion duct A having a length about 5 to 10 times the length of the storage case 1 could be stored.

[0013]

Advantageous Effects of Invention According to the first aspect of the invention, the end of the telescopic duct having one end inserted in the storage case is brought into contact with the bottom surface, and the other end of the telescopic duct is capped. By connecting the suction hole to a vacuum source and pushing the telescopic duct into the storage case while sucking the air in the telescopic duct, the telescoping duct about 5 to 8 times the length can be easily stored in the storage case. It can be stored inside and is easy to store and store. Moreover, when the expansion duct is taken out of the storage case, the blocking piece prevents the expansion duct from popping out and the necessary amount can be pulled out and used.

According to the second aspect of the invention, the blocking piece can be formed by effectively utilizing the flap, and the blocking piece can be easily manufactured.
