BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disposable paper pack mainly used for household vacuum cleaners.

[0002]

2. Description of the Related Art Conventionally, in household vacuum cleaners, disposable paper packs of a type that can be attached to and detached from the inside of an insertion port of a nozzle hose have been widely used. As one of the seed paper packs, a tubular body is formed from a relatively fine outer layer filter paper and a coarser inner layer filter paper, and a longitudinally opposed end of the tubular body is formed.
Folding by superimposing each of the edges twofold form, closed by bonding the folded portion to the surface of the cylindrical body while, tubular
Thereby to removably cleaner by bonding the mounting member made of cardboard the required site of Jo body, this member center portion has a structure in which a dust suction port. This paper pack has a double filter structure and is resistant to clogging and has excellent dust collection performance. In addition, the inner and outer layer filter papers are overlapped in advance and laminated as an intermittently laminated paper to make it as if one paper By processing these two filter papers at the same time as processing paper, a paper pack can be efficiently produced.

[0003]

In a paper pack having a double filter structure, if a bulky inner filter paper is used in place of the coarse inner filter paper, the path of the air passing through the filter is complicatedly bent, and By increasing the distance, a decrease in suction force can be suppressed even if the amount of collected dust increases, and the performance of the cleaner can be improved. As the bulky filter paper, for example, a nonwoven fabric having a thickness of 0.3 to 3 mm having an appropriate density can be used, and this thickness corresponds to about three to several tens times that of the conventional inner layer filter paper. Therefore, there is a problem in using this bulky filter paper as a laminate paper with the outer layer filter paper as in the past. For example, since such a laminated paper is bulky, it is not always easy to overlap and bend the longitudinally opposed edges of the tubular body . Also, when the widthwise opposing side edges of the laminated paper are overlapped and bonded to form a cylindrical body, the widthwise side edges of the bulky inner layer filter paper are bonded to the widthwise outer edges of the cylindrical body at the bonded portions.
It faces the parts, and decrease the suction force therefrom cause air leakage,
It may lead to spillage of garbage.

[0004] This invention is based on the formation of outer layer filter paper.
From the lengthwise inner dimension of the outer edge of the cylindrical outer bag
Also the length dimension of the tubular inner bag formed from inner layer filter paper
It is an object of the present invention to solve the above problem by reducing the size of the method .

[0005]

The gist of the present invention to solve the above problems is as follows.

[0006] This invention is directed to a vacuum cleaner paper pack comprising a relatively fine outer layer filter paper and a coarser inner layer filter paper, and having a dust suction port and means for attaching to the inside of the vacuum cleaner. I have.

[0007] This invention is, in the paper pack, the

DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of this invention will be described below with reference to the accompanying drawings.

FIG. 1 is a perspective view of a paper pack 1 according to the present invention, which is developed on a plane with its upper surface facing downward, and partially cut away. The paper pack 1 is a bag having a rectangular planar shape, and has an upper surface 2, a lower surface 3, a side edge 4 in the width direction , and an edge 5 in the length direction. A mounting plate 6 made of cardboard for the machine body (not shown) is adhered around the suction port 7. Side edges 4 have a 2 Article folds 9 by providing a folding 8 in the inward direction
Then, when a suction force acts, air and dust are taken in from the suction port 7, and the folds 9 expand. Cartons 1, and consists, as shown by the broken portion forms an outer layer filter paper 10A is formed from the outer bag 10 and the inner filter paper 11A that whole circumference is closed <br/> entire circumference of the closed inner bag 11 Metropolitan And the suction port 7
The two filter papers are joined together around.

FIG. 2 is a view taken along the line XX in FIG. The outer bag 10 is opposed to the outer layer filter paper 10A in the width direction.
The side edges are overlapped and airtightly adhered with an adhesive 15 to form a cylindrical body 10B except for the longitudinally opposed edges.
It has been done. Inner bag 11A is made of inner layer filter paper 11A.
By overlapping the width-direction facing side edges and bonding them with the adhesive 16, a tubular body 11 </ b> B that fits inside the outer bag 10 except for the length-direction facing edges is formed . However, in the unused paper pack 1 as shown in FIG. 1, the tubular body is folded inward from the side and flattened . The inner bag 11 and outer bag 10, are suitably adhered by adhesive 17 to contact surfaces of one another.

FIG. 3 is a view taken along the line YY of FIG.
The state where the lengthwise facing edges of the outer bag 10 and the inner bag 11 are closed is shown. Outer bag 10 is made of outer layer filter paper 10A.
After the upper and lower surfaces of the paper pack 1 are overlapped in a palm- shape manner, the lengthwise facing edge portion 14 is bent twice at the bending portions 25 and 26 with the lower surface 3 of the paper pack 1 inside, and then the bent portion is brought into contact with it. the portion of the outer layer filter paper 10A which are bonded by an adhesive 20. On the other hand, the inner bag 11 is located above and below the longitudinally facing edge 21 of the inner filter paper 11A.
The surfaces are overlapped in a jointed manner and adhered by an adhesive 22. Between the longitudinally opposed edges of the inner layer filter paper 11A
Dimensions, internal longitudinal pair of outer pouch 10 / cylindrical body 10B of
Adhesive length is smaller than the dimension between the opposite edges
The edge 21 in the vertical direction is located inside the bent portion 26 of the outer layer filter paper 10A, and the outer layer filter paper 1
With the bent part 25 of 0A , of course,
It is designed so that it will not be folded in . Folding of outer layer filter paper 10A not including inner layer filter paper 11A
The bending at the bent portions 25 and 26 is easy even when the inner layer filter paper 11A is bulky.

FIG. 4 shows the outer bag 10 and the inner bag 11 respectively.
3 shows a state in which the longitudinally facing edge portions 14 and 21 are closed in a manner different from that in FIG. In this figure, the outer bag 10 is closed as in FIG. 3, the length direction opposing edges of the inner bag 11
Is so as not to overlap with the folded portion of the longitudinal opposite end edge of the outer bag 10, further outer bag than in FIG 3
It is closed by a joining line 27 located near the center in the length direction of the cable 10 . For example, when the outer filter paper 10A is a heat-resistant natural fiber and the inner filter paper 11A is a heat-fusible synthetic fiber, the inner filter paper 11A is subjected to ultrasonic treatment via the outer filter paper 10A. In this case, it is preferable to remove the folded portion where the outer filter paper 10A is thickly overlapped and to perform ultrasonic treatment.

The filter paper in the present invention means a material such as papermaking, synthetic paper, woven fabric, nonwoven fabric, etc., which can be used as a filter. The bonding of these materials includes fusion by ultrasonic waves or the like in addition to adhesion with a conventional adhesive or pressure-sensitive adhesive, and the adhesion can be appropriately changed to fusion.

In the paper pack 1 configured as described above, the mounting plate 6 whose outer shape is adjusted according to the model of the vacuum cleaner is mounted on a predetermined mounting portion provided inside the nozzle hose insertion port of the cleaner body. The mounting plate 6 is detachable from the main body of the cleaner, and the paper pack 1 swollen by collecting dust is appropriately replaced with a new one.
