Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dust bag, and more particularly to a dust bag for an electric vacuum cleaner.

[0002]

2. Description of the Related Art Conventionally, the structure is as shown in Japanese Patent Publication No. 3-10326.

A description will be given below with reference to FIG. Dust bag 1
Is connected to one side of a core 4 provided with a dust suction port 3 communicating with the inside of the paper bag 2 and is provided with a lid 6 having a cut groove 5 at the tip thereof, and the core 4 and the lid 6 are provided. A folding line 7 is provided between and, and when the dust bag 1 is filled with dust and the dust is discarded, the lid body 6 is folded along the folding line 7 toward the dust suction port 3 side to open the dust suction port 3. The dust in the cover dust bag 1 is prevented from spilling.

[0004]

However, in the structure of the above-mentioned conventional example, when the dust is thrown out, the dust collecting bag is taken out, the lid body 6 is folded to prevent dust, and the dust suction port 3 of the core 4 is covered. It is unsanitary because it takes time to set the body 6 and dust spills when the lid 6 is folded. Furthermore, the lid 6
Since it is formed so as to protrude from the mouth core 4, the mouth core 4 becomes large, and accordingly, the dust collection chamber must be made large, and therefore the electric vacuum cleaner body becomes large and the cost is increased. Further, in recent years, the disposal of household electric appliances and the like has been highlighted, and the main body of the electric vacuum cleaner has become large, which has been a heavy burden when the main body of the electric vacuum cleaner is disposable. Further, since the lid 6 is formed at one end of the mouth core 4, the cost of the mouth core 4 is high, and the burden is very heavy in a disposable paper bag, which causes various problems.

The present invention solves the above problems,
An object of the present invention is to provide a dust bag for an electric vacuum cleaner that is hygienic and can be used more easily.

[0006]

In order to achieve the above object, a dust bag of an electric vacuum cleaner according to the present invention is made of a filter material such as air-permeable paper and has a bag-like body for collecting dust. It has a dust suction port communicating with the bag-shaped body, is attached to the outer wall of the bag-shaped body, and is composed of a core having an opening connected to the dust suction port of the bag-shaped body, and this core has the above-mentioned It has a lid partly formed integrally with the mouth core when forming the opening.

Further, a partial recess or projection is formed on the lid. Further, it has a fixing means for fixing the lid body to the mouth core in a state of being bent toward the mouth core side.

Further, the lid body is formed by step-cutting so as to project outward from the opening of the mouth core.

Furthermore, the vacuum cleaner provided with the device for mounting the dust collecting bag of the vacuum cleaner according to the present invention has a lid body and a mouth when the lid body is bent in the mouth core side and installed in the dust collection chamber. A restricting body composed of a rod or a plate positioned between the core and the core is arranged above the intake port in the dust collecting chamber.

[0010]

According to this structure, the lid body having substantially the same shape as the opening of the core that communicates with the dust suction port of the bag-shaped body is partially formed integrally with the core, which has been a waste material in the past. A lid can be formed by using a member, and a lid is not required for other parts of the core, the core can be made smaller, and the cost can be reduced.
Also, since the lid is bent from the core when the dust bag is installed in the dust chamber, it is possible to save the labor of bending the lid when disposing of the dust, which improves usability and covers the opening of the core with the lid. Sometimes dust is not spilled and it is hygienic.

Further, by forming a concave portion or a convex portion in a part of the lid body, it can be used as a finger hook when the lid body is taken out from the opening of the mouth and bent, and the lid body is easily opened for use. It is possible to improve the sex.

Further, by providing a fixing means for fixing the lid body to the mouth core in a folded state, the folded mouth core is prevented from being lowered when the dust bag is mounted in the dust collecting chamber, and the dust collecting bag is collected. It improves the attachability of the dust bag.

Further, since the lid body is formed so as to be stepped out so as to be located outside the opening of the mouth core, the lid body can be easily opened by the step, and the shape and the opening of the lid body can be easily opened. Since the shapes of (1) and (2) are almost the same, the opening can be closed almost completely and dust can be prevented from leaking.

Furthermore, when the dust collecting bag is mounted in the dust collecting chamber, a regulating body made of a rod or a plate is arranged between the lid and the mouth core above the intake port in the dust collecting chamber, so that the dust collecting bag is provided. If the core is pulled upward when the is taken out from the dust collecting chamber, the lid is pressed by the regulation body to close the opening of the core.
Therefore, when the dust collecting bag is taken out of the dust collecting chamber, the lid automatically covers the opening so that the lid can be saved and the lid can be closed without soiling the hand, which is hygienic.
