Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a disposable paper bag for use in a vacuum cleaner, in which the opening paper is folded in half to close the intake hole.

A paper bag whose opening is folded in half to close the intake hole may have the disadvantage that if the bag is full of dust, the dust in the paper bag will be pushed out when the opening is folded, staining hands.

The present invention aims to provide an effective and inexpensive opening structure to overcome this drawback. Another object of the present invention is to achieve the above object and at the same time to provide a check valve to prevent dust adhering to the extension hose from spilling out from inside the paper bag when the extension hose of the vacuum cleaner is attached and detached from the main body. The purpose is to provide a structure for the mouthpiece that can perform both functions at the same time.

Examples will be described below with reference to the attached drawings. 1st
In the figure, 1 is a filter paper that serves both as a filter and a dust collection container, and a cover 2 made of rectangular cardboard is attached to the - side. A suction hole 3 is formed in the center of the slip 2, and a fold 4 is perforated at a position dividing the suction hole 3 into two.

A cutout portion 5 and a cutout portion 6 are formed at an end portion of the cover sheet 2 at a position symmetrical to the fold line 4. and filter paper 1
Between the opening paper 2 and the opening paper 2, two pieces of interleaving paper 7 folded in half as shown in FIG.
Gluing is done at the hatched areas in FIGS. 1 and 2 with a spacing of 100 mm.

Next, we will discuss how to use this paper bag.

FIG. 3 shows the configuration of a vacuum cleaner using a paper bag according to this embodiment. It is movably attached and engages with the main body 8 by means of a buckle 13.

A pair of upper and lower inner lids 14.15 are rotatably disposed in the opening, and a part of the inner lid 14.15 has a holding portion (not shown) that holds the opening 2 of the paper bag. is formed. When attaching the paper bag to the main body 8, fold the filter paper 1 to make it compact and easy to handle by hand.
'9M14.1tscr) Dust collection box 1 of main body 8 through
6, and the opening paper is brought into contact with the holding portion of the inner lid 14, 15 to support the paper bag. Then, the front cover 11 is closed and the opening paper 2 is clamped, and the suction hose 17 shown in FIG.
A front cover 11 is attached to the paper bag, and an electric blower 9 blows in dust to collect it inside the paper bag. At this time, the filter paper 1 is spread into the dust collection box 16 by the suction force of the electric blower 9. As shown in FIGS. 4 and 5, the suction hose 17 is inserted into the middle of the paper bag, and the paper 7 is pressed and bent inward so that it is in close contact with the periphery of the suction hose 17. . When the suction hose 17 is pulled out from the main body, the interleaving paper 7 returns to its original state, and the suction hole 3 is closed leaving a slight gap to prevent dust from leaking. Further, when the suction hose 17 is removed from the main body, the dust that adheres to the suction hose 17 and spills outside can be scraped off with the interleaving paper 7 and collected in the paper bag, thereby preventing the main body of the vacuum cleaner from getting dirty.

When the paper bag is full of dust and it is time to discard it, as shown in FIG. 3, squeeze both ends of the opening paper 2 and hold it folded in half at the crease 4, and pull out the filter paper 1. At this time, the inner lids 14 and 15 are pushed by the filter paper 1 and rotated, so that the paper bag can be taken out without resistance. And this inner lid 14
．． Since the area of the opening sheet 2 can be made smaller than the area of the opening by an area of 15, the opening sheet 2 can be sufficiently folded with one hand.

When folding the cap 2, in the conventional cap structure, the filter paper 1 is pulled by the adhesive portion with the cap 2 and its volume is reduced around the intake hole 3, as shown in FIG. This has the disadvantage that the dust inside the paper bag is pushed out and makes your hands dirty. However, in this embodiment, as shown in FIG. 7, even if the opening paper 2 is folded, the two folded sheets 7 open at right angles, so the filter paper 1
The volume of the paper bag hardly changes, the dust in the paper bag is not pushed out, and the force required to bend it is also small. Therefore, it is easy to operate and does not get your hands dirty. The paper bag pulled out from the main body can be fixed closed by pressing the cutout 6 into the cutout 5 of the opening paper 2, so even if it is thrown into an indoor trash can etc. and disposed of, the impact of dropping will prevent the paper bag from being damaged. There is no chance of dust rising up again and blowing out of the intake vents.

As described above, the present invention reduces the force required when folding the opening paper 2 in half by providing the interleaving paper 7, and in particular prevents dust from blowing out from inside the paper bag, improving operability and cleanliness. It is possible to improve the Furthermore, since the interleaving paper 7 can also function as a check valve, it is particularly effective as a means for achieving many purposes at low cost.
