Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a pack filter for a vacuum cleaner, and more particularly to a pack filter for a vacuum cleaner that can be used in any type of vacuum cleaner.

[Conventional technology]

Conventionally, disposable paper pack filters have often been used as dust collection filters for vacuum cleaners.

FIG. 4 is an external view of a conventional vacuum cleaner pack filter. This filter consists of a mouth core 1 and a pack filter body 2. The mouth core 1 is made of cardboard or the like, and is attached to the opening of the pack filter body 2, and connects the filter attachment part of the vacuum cleaner 3 and the pack filter body 2, as shown in FIG. However, the shape of the mouth core 1 differs depending on each manufacturer, and for example, mouth cores having the shapes shown in FIGS. 6 to 8 are used. Therefore, there is an inconvenience that the pack filters are not compatible and cannot be used with other vacuum cleaners.

Also, when using a mouth wick, there is a gap between the vacuum cleaner and the mouth wick,
There is a problem of dust leakage, and the cost of the pack filter itself increases due to the addition of a wick.

[Problem to be solved by the invention]

SUMMARY OF THE INVENTION An object of the present invention is to eliminate the problems of the prior art described above, to provide a pack filter for a vacuum cleaner that can be easily attached to and removed from any vacuum cleaner and that does not leak dust during use.

[Means to solve the problem]

The present invention relates to a pack filter for a vacuum cleaner comprising a bag-shaped filter having an opening and a double-sided adhesive sheet whose negative side is adhered around the opening.

〔Example〕

Hereinafter, the present invention will be explained in detail with reference to Examples.

FIG. 1 is a front view of a pack filter for a vacuum cleaner showing an embodiment of the present invention, and FIG. 2 is a sectional view taken along the line ■-■ in FIG. This pack filter consists of a bag-shaped filter 2 having an opening 5 and a double-sided adhesive sheet 4 connected to the periphery of the opening 5 on one side.

The bag-shaped filter used in the present invention is made of, for example, nonwoven fabric or paper, and the material thereof may be cellulose, synthetic fiber, glass fiber, or the like.

The opening provided in the bag-shaped filter refers to one hole provided in the bag-shaped filter, but the shape thereof may be a square, a triangle, or the like in addition to a circle.

The double-sided pressure-sensitive adhesive sheet used in the present invention is a pressure-sensitive adhesive sheet coated with a pressure-sensitive adhesive or an adhesive on both sides.

One side of the sheet is glued around the opening of the bag-shaped filter, and the other side coated with adhesive is glued to the filter attachment part of the vacuum cleaner when the filter is connected to the vacuum cleaner. .

Note that the adhesive on the side that connects to the area around the opening of the filter may be a sticky adhesive, but the adhesive on the side that attaches to the filter attachment part of the vacuum cleaner may be a so-called adhesive that can be removed and attached. Agents are preferred. The adhesive surface to the vacuum cleaner is preferably covered with a sheet or film that does not inhibit the adhesiveness of the adhesive sheet during use when not in use.

The adhesive sheet is preferably an elastic sheet made of rubber, urethane, or the like, but may also be a sheet made of thermoplastic resin or the like. The thickness of the sheet is 0.05
It is preferably at least u, more preferably at least 0.1.

If the thickness of the sheet is too thin, the strength of the sheet may be too low and it may break.

The size of the sheet is not particularly limited as long as it can be easily adhered when connecting the opening to the vacuum cleaner. For example, in the case of the circular opening shown in Figure 1, the width is 8~12C! L, vertical L! is preferably 8 to 12c11.

The adhesive used in the adhesive sheet is not particularly limited, and common adhesives such as synthetic rubber, urethane, and silicone adhesives used in general cellophane tapes can be used.

The adhesive strength of the adhesive should be such that it does not come off during use and can be easily removed after use, and specifically, it is preferably 1 to 4 kg/inch, and the adhesive strength is 1) cg/inch. If it is less than 4 kg/inch, the pack filter may come off during use, and if it exceeds 4 kg/inch, it may be difficult to remove or the pack filter may be torn. Note that the adhesive strength in this case is measured by a tensile strength test as shown in FIG. That is, a sheet 8 to which the pack filter material is adhered is adhered to a plastic plate 6, a spring balance 7 is attached to the tip of this sheet 8 (A), and the value of the spring balance when the sheet is peeled off (B) is calculated. It was measured.

Example 1 A double-sided adhesive sheet 4 (vertical 9
5III11, Yoko85kaku, sheet thickness 0.1 mm) was pasted on one side, and the other side of the adhesive sheet 4 was pasted on a commercially available vacuum cleaner and connected. The adhesive strength of the adhesive sheet at this time was 3.5 kg/inch. When this vacuum cleaner was used, there was no leakage of dust during use, and the filter was easy to remove after use.

〔Effect of the invention〕

According to the vacuum cleaner pack filter of the present invention, it is possible to eliminate the leakage of minute dust during use, and the filter can be easily attached and detached to any type of vacuum cleaner.
