JP2001269296A - Dust collecting bag of vacuum cleaner - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a dust collecting bag for a longitudinal vacuum cleaner or the like that doesn't easily get swollen and ruptured while sucking dusts from an upper lateral inlet. SOLUTION: A dust collecting bag whose upper square surface is sealed with an adhesive or the like and the other edge is folded and sealed with an adhesive or the like includes a suction inlet provided with the lateral surface adjacent the upper surface of a bag-shaped body and a ground paper to be integrally attached with the vacuum cleaner with an adhesive, etc., so that a fully swollen bag-shaped body adjacent the ground paper doesn't cause a strong force that may hit the wall of the vacuum cleaner when or after it sucks the dusts.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a used dust collecting bag used in an electric vacuum cleaner, especially a vertical vacuum cleaner.

[0002]

2. Description of the Related Art FIG. 5 shows a dust-collecting bag for a vacuum cleaner disclosed in, for example, Japanese Utility Model Laid-Open No. 1-112543. In a vertical vacuum cleaner that sucks dust together with air from the horizontal direction near the upper end of a vertically long dust collection chamber, as shown in FIG. 5, a cylindrical end having a turn-back 21 on both sides is sealed, and the other end having a suction port is a vacuum cleaner. It is glued together with a mount to be mounted on the wrapper and sealed to form a bag.

[0003]

In the above dust collecting bag, even if the bag is swollen at the suction port position, it does not reach the dust collecting chamber wall. When the vacuum cleaner is operated with a large amount of garbage sucked in near the suction port and the vacuum cleaner is activated, the bag expands due to a pressure difference between the inside and outside of the bag. Since the end of the bag is adhered together with the mount, the bag is not peeled off from the mount, but the bag may be torn.

[0004]

The present invention is configured as follows. (1) The rectangular part folded in the shape of FIG. 2 is sealed by bonding or the like, the other end is folded back and sealed by bonding or the like, and a suction port is provided near the square side end surface to form a bag-like body, and a vacuum cleaner having the same suction port In this case, a backing made of cardboard or the like to be mounted on the base is integrated by bonding or the like so that the suction ports are aligned.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS First Embodiment FIGS. 1 to 3 show a first embodiment. FIG. 1 is a perspective view of the dust bag. The square at the upper end seals the overlapping portion 10 of FIG. 2 by bonding or the like. A sheet may be affixed to increase the sealing. The other end is sealed by folding and bonding. A suction port 12 is provided near the square end face to form a bag 13. Reference numeral 14 denotes a mount made of cardboard or the like to be attached to the vacuum cleaner. The backing sheet 14 also has a suction port,
Are integrated by bonding or the like at a position where the suction port 12 of the base paper 14 and the suction port of the mount 14 coincide with each other. FIG. 3 shows the shape of the dust bag just attached to the vacuum cleaner. When the vacuum cleaner is operated in this state, the bag-like body 13 easily expands greatly. Among them, the part near the mount is the largest and bulges and hits the dust collection chamber wall.

[0006]

According to the present invention, in a vacuum cleaner having a vertically long dust collecting chamber and having a suction port in the horizontal direction near the upper end, the upper end is sealed with a square flat surface by bonding or the like, and the lower end is sealed by folding back and bonding. When a dust bag is attached to a bag made of paper or other material that has a suction port on the side, and a cardboard made of cardboard or the like is attached to the vacuum cleaner by gluing, etc., the dust is collected when the vacuum cleaner is activated. The bag opens and swells. At that time, the area near the mount is blistered most, and the bag-like body hits the wall of the dust collection chamber. With a dust bag with such a structure, even after a considerable amount of dust is sucked in, the dust bag always hits the wall of the dust collection chamber at the position of the suction port. There is no problem that the bag-like body is torn or the backing and the bag come off.

2. Description of the Related Art FIG . 4 shows a dust bag for a vacuum cleaner disclosed in, for example, Japanese Utility Model Laid-Open Publication No. 1-112543. In a vertical vacuum cleaner that sucks dust together with air from the horizontal direction near the upper end of a vertically long dust collection chamber, as shown in FIG. 4 , a cylindrical end having a turn-back 21 on both sides is sealed, and the other end having a suction port is a vacuum cleaner. It is glued together with a mount to be mounted on the wrapper and sealed to form a bag.
