Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dust bag used for collecting dust in a vacuum cleaner.

[0002]

2. Description of the Related Art Conventionally, as a dust bag for a vacuum cleaner, a peripheral edge of an opening portion of a filter bag is adhered to a peripheral edge of the opening portion of a mounting board made of cardboard having an opening portion, and electric power is passed through the mounting plate. 2. Description of the Related Art A device that can be connected to and attached to a suction hole of a vacuum cleaner is widely known. This dust bag is set in the dust collection chamber of the vacuum cleaner, and plays a role of capturing and collecting dust sucked into the filter bag from the suction hole of the vacuum cleaner when the pressure in the dust collection chamber is negative. It is.

[0003] The size of the mounting plate, the position and shape of the mounting notch (reverse insertion preventing concave portion and positioning slit, etc.) formed on the mounting plate differ from manufacturer to manufacturer. Has become. From this, a discontinuous cut is formed on the mounting plate to adjust the size according to the specifications of each manufacturer and to form a cutout for mounting, etc. There is known a common type dust bag in which the bag can be used for vacuum cleaners of different manufacturers (Japanese Utility Model Publication No. 6-37808).

[0004]

However, the conventional dust bag is thick and durable so that the close contact with the suction hole of the vacuum cleaner can be reliably maintained at the time of suction, regardless of whether the dust bag is of a common type or not. Although it is provided with a suitable mounting plate, it is disposable including this part, and there is a problem that there is much waste in material.

[0005] Further, in the conventional common type dust bag, when cutting along the discontinuous cut, the discontinuous portion of the cut cut remains as a protrusion, and the protrusion is accurately placed in the suction hole of the vacuum cleaner. A problem is that such a connection is hindered and a gap is easily formed between the mounting plate and the suction hole. When this gap is generated, a part of the sucked dust leaks into the dust collection chamber of the vacuum cleaner, causing dirt in the dust collection chamber and clogging of the filter on the front surface of the suction device. The fact that the mounting plate is thick and durable as described above promotes the generation of the protrusions, and also makes it difficult to cut out necessary parts.

In addition, the conventional common type dust bag has a problem in that it is necessary to confirm which part is to be cut off each time the dust bag is replaced, and the replacement operation is troublesome. In particular, since the replacement of the dust bag is not done so frequently, it is easy to forget the cutout point, and when installing a new dustbag after discarding the used dustbag, the cutout point may not be known I do.

[0007] The present invention has been made in view of the above-mentioned conventional problems, and has as its first object to reduce waste of material in a disposable part. Further, the present invention provides a dust bag that can be easily attached to vacuum cleaners of many manufacturers without performing a partial cutting operation of a mounting plate according to the specifications of the vacuum cleaner manufacturer. This is the second purpose.

[0008]
