JP3030936U - Dust bag for vacuum cleaner - Google Patents

Abstract

(57) [Summary] [Structure] A bag formed by joining a filter material such as paper and a transparent resin film into a tubular shape, and a suction port attached to the suction port of the bag-shaped body in which both end openings are joined. Use of dust collection bag of vacuum cleaner formed by supporting member [Effect] When the dust collection chamber cover of the vacuum cleaner is opened, the inside of the dust collection chamber can be seen, so the amount of dust can be seen at a glance. Further, by treating the filter material such as paper, welding can be performed and the process of manufacturing the bag-shaped body can be simplified.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a disposable dust bag for a vacuum cleaner.

[0002]

[Prior art]

 Conventional dust collection bags for vacuum cleaners are made by folding one sheet or two sheets of filter media such as paper into a tubular shape and adhering them, and then folding and adhering the openings at both ends of the tube to form a bag shape. ing.

[0003]

[Problems to be solved by the device]

 With a conventional dust bag for an electric vacuum cleaner, since the bag is a filter material such as paper, it is not known how much dust is contained in the electric vacuum cleaner.

In addition, in the step of forming the dust collecting bag into a bag shape, the filter material has to be repeatedly folded and adhered.

The present invention is intended to provide a dust bag for an electric vacuum cleaner that can solve these drawbacks.

[0006]

[Means for Solving the Problems]

 A sheet in which a filter material such as paper and a transparent resin film are joined is folded back into a tubular shape, and the openings at both ends are joined to form a bag-shaped dust collecting bag.

[0007] Furthermore, a filter material such as paper is treated so that it can be welded, and the openings are welded to form a bag.

[0008]

[Action]

 By attaching the dust bag of the present invention to an electric vacuum cleaner, the inside of the dust bag can be seen when the cover of the dust collecting chamber of the vacuum cleaner is opened, and the amount of dust can be seen at a glance.

Further, the process of forming the sheet into a bag can be simplified by joining the openings at both ends of the cylinder by welding.

[0010]

【Example】

 Example 1 is shown in FIGS.

A part of the filter material such as sheet-shaped paper (the position visible when the dust collecting chamber cover is opened when the dust collecting bag is formed into a bag) is replaced with a transparent resin film, and the overlapping portion is joined. 2 is folded and adhered to form a cylindrical shape as shown in FIG. 2, and openings at both ends are folded and adhered to form a dust collecting bag as shown in FIG.

Example 2 is shown in FIGS.

When formed into a bag shape, the opposite surface of the supporting member is formed of a filter material such as paper, the supporting member side and the bellows portion are formed of a transparent resin film, and the hatched portion of FIG. A dust bag is formed, and the area on the opposite side is larger than that on the support member side.

[0014]

[Effect of device]

 According to the structure of claim 1, when the dust collecting chamber cover of the electric vacuum cleaner is opened, the amount of dust in the dust collecting chamber can be known, and the replacement time of the dust collecting bag can be known.

According to the configuration of claim 2, the step of changing from the sheet shape to the bag shape can be simplified during the dust collecting bag manufacturing step.
